Description

  The present invention relates to a support structure for fixing an electronic device in a vehicle interior and an electronic device using the same.

  Some in-vehicle devices that are installed in the vehicle are pre-installed in the corresponding part of the dash panel at the time of factory shipment, etc., but in the case of aftermarket products for optional equipment, the assembly part is secured in the dash panel. Most things you cannot do. For this reason, many of such in-vehicle devices are often arranged on the dashboard for convenience of operation by the driver. For example, an in-vehicle device having a display panel such as a navigation device obtains not only a driver's operability but also a forward visibility, so a position that does not hinder driving is selected on the upper surface of the dashboard. Furthermore, for example, in an in-vehicle device provided with a display device, there is a demand for adjusting the orientation so that the driver can easily see the display screen. For this reason, the vehicle-mounted device may be installed on a dashboard or the like via a vehicle-mounted device support that can change the posture of the vehicle-mounted device.

  As this type of vehicle equipment support, for example, there is a technique disclosed in Patent Document 1. The invention disclosed in Patent Document 1 includes a pedestal [21] to be attached to a dashboard, an attachment member [22] to be rotatably attached to the upper surface of the pedestal [21], and an in-vehicle device, and the pedestal. [21] and an operation screw [23] and a set screw [24] for fixing the mounting member [22], and the pedestal [21] is a hemispherical surface portion [21] provided on the upper surface of the flat substrate portion [21a]. 21b] is provided with an opening [21c]. The attachment member is provided with a through hole [22f] at the apex portion of the spherical receiving portion [22b] having an inner shape coinciding with the hemispherical portion on the lower surface of the strip [22a]. The operation screw is provided with a male screw portion [23b] on the lower surface of the operation handle portion [23a]. The set screw is provided with a female screw part [24c] that matches the male screw part on a shaft part [24b] provided on the upper surface of the base part [24a] that matches the inner peripheral surface of the hemispherical part. By taking such a configuration, it is possible to fix the vehicle-mounted device in an arbitrary posture, and it is possible to reduce the size with a simple configuration. In addition, the code | symbol in said parenthesis is a code | symbol used in patent document 1. FIG.

JP 2009-166756 A

  However, when the mounting screw portion is arranged on the pedestal side as in Patent Document 1, the following problems occur. That is, since an operation screw and a set screw for fixing them are arranged between the pedestal and the mounting member for mounting the in-vehicle device, at least the operating screw is provided between the pedestal and the mounting member. Space is vacant, and the installation position of in-vehicle equipment becomes high. For example, a relatively flat device such as the in-vehicle device disclosed in Patent Document 1 is not so affected even if such a configuration is adopted. For example, a simple portable car navigation system called a PND (Personal Navigation Device) is used. In-vehicle devices with a relatively large display screen, such as devices, portable TVs, DVD players and other portable devices, and alarm devices that provide useful information for driving such as surrounding objects and traffic accidents If the installation position becomes high, there is a risk that it may be in the way of securing the forward field of view when performing normal driving. In particular, since the display screen has recently become larger in this type of in-vehicle device, such a problem may occur significantly in the future. Therefore, when various electronic devices are mounted on a dashboard or the like, there is a problem that the installation height is to be kept low.

  In order to solve the above-described problem, a fixture for on-vehicle equipment according to the present invention includes (1) a board portion that is fixed to a mounting surface of a vehicle, and a hemispherical portion that swells upward provided on the upper surface of the board portion. A pedestal having an opening at the apex portion of the hemispherical portion, and a spherical receiving portion having an inner shape matching the outer shape of the hemispherical portion on the bottom surface, and a screw portion at the apex portion of the spherical receiving portion And a case main body movably attached to the upper surface of the pedestal portion. The case body is a holding unit for attaching the electronic device itself or the electronic device, and the hemispherical portion is placed on the lower surface side of the hemispherical portion with the spherical receiving portion covered on the hemispherical portion. A fastener having a base portion having an outer peripheral surface coinciding with the inner peripheral surface and a shaft portion protruding upward on the upper surface of the base portion is mounted, and the spherical surface receiving portion penetrates the shaft portion through the opening. The hemispherical portion is sandwiched and fixed between the fastener and the spherical receiving portion with a desired force by facing the screw portion provided on the screw portion and connecting with a set screw fastened to the screw portion.

  The case body corresponds to the cradle body 11 in the embodiment, but may be an electronic device itself. A mounting part (fastening part of the set screw and screw part) such as a ball joint consisting of a hemispherical part and a spherical receiving part is placed inside the case body, and a fastener and set screw are attached from below the base part. Since the set screw can be tightened or loosened, the distance between the bottom surface of the case main body and the base plate portion of the pedestal portion can be narrowed, and the bottom surface position of the case main body can be lowered. As a result, the installation position of the case main body or the electronic device attached to the case main body can be lowered, and front visibility is improved.

  (2) A fixing sheet for detachably fixing to the mounting surface is provided on the lower surface of the substrate portion, and a hole portion is provided in the fixing sheet, and the screw of the set screw is provided through the hole portion. The head should be exposed. In this way, even after the case body (electronic device) is attached to the mounting surface of the vehicle such as the dashboard, the screw head is exposed through the hole when it is removed from the mounting surface. By moving the relative positional relationship between the case main body and the pedestal portion and tightening the set screw at a desired position, the posture of the case main body with respect to the pedestal portion and thus the mounting surface of the vehicle can be easily changed. The fixing sheet may be a hook-and-loop fastener, for example.

  (3) The case body includes a bottom case in which the spherical surface receiving portion is formed and a case portion (in the embodiment, the front case 20 and the rear case 21) that covers the top of the bottom case. A circuit board may be disposed on the upper surface side, and the circuit board may have a shape that avoids the spherical receiving portion. The internal space on the bottom surface side of the case body becomes a dead space with the spherical receiving portion entering, but since the circuit board can be arranged on the bottom surface side so as not to interfere with the spherical receiving portion, the space can be effectively used.

  (4) The circuit board may be provided with a power connector, and the power connector is exposed on the side surface of the case body. The power connector can be equipped with a connection cable that connects to a vehicle-side battery such as a vehicle cigar socket. As a result, power can be supplied from the vehicle side, and power can be supplied from the electronic circuit / device provided on the circuit board or other case body.

  (5) The case portion is configured to have a substantially L-shaped cross section, and a main board is mounted in a standing space of the case section, and the main board and the circuit board are connected by a flexible cable. Good. A board | substrate can be efficiently arrange | positioned in the space in a case main body.

  (6) A microwave receiver may be provided in the space portion in parallel with the main board. A function of receiving microwaves can be efficiently incorporated into the case body. The case main body can constitute a part of the in-vehicle device (electronic device). In particular, when the electronic device is detachable from the case body and can be removed from the case body and carried, information useful for detecting microwaves and driving in areas with frequent traffic accidents, etc. A part of the in-vehicle device that provides Such information is necessary when driving, but is an unnecessary function when it is removed from the case body, taken out of the vehicle and carried. In view of this, by incorporating, in the case body, a component that realizes a function that is effective only when the vehicle is mounted, among the functions that constitute the electronic device, the electronic device can be reduced in size and weight when it is carried. The signal received by the microwave receiver uses a control unit such as a microcomputer in the electronic device attached to the case main body, so that the case main body becomes a part of the on-board electronic device, and the electronic device including the case main body As a result, the components can be effectively arranged, and the overall size can be reduced.

  (7) An electronic apparatus according to the present invention includes the support structure according to any one of (1) to (6).

  When installing various electronic devices on a dashboard or the like, the installation height can be kept low.

1 is an overall perspective view showing a preferred embodiment of the present invention. FIG. It is the perspective view seen from the bottom. It is a side view. It is a bottom view. It is a perspective view which shows the state which removed the front case and the rear case, and some components of the cradle main body. It is a side view which shows the state which removed the front case and the rear case, and some components of the cradle main body.

  FIG. 1 is a perspective view showing a preferred embodiment of a vehicle-mounted device fixture according to the present invention, FIG. 2 is an exploded perspective view thereof, and FIG. 3 is a perspective view as viewed from the bottom side (in the dashboard). It is the figure which removed the hook-and-loop fastener to attach. The electronic devices to be held here are, for example, portable car navigation devices (PNDs) that can be carried, microwaves emitted from vehicle speed measuring devices, radio waves assigned to car locator systems, speed control communication radios, and the like. A radio signal notification device that receives radio waves in a specific frequency band such as when a target radio wave is received and notifies the user by displaying sound, light, etc., and is present around it based on current location information detected by a GPS receiver, etc. Drives that report traffic safety information, landmarks, and various information useful for driving, such as pre-recorded information on targets to be detected, accident-prone areas, traffic control information, etc. There are information reporting devices. And these various apparatuses are comprised also as a single apparatus which implement | achieves each function, and are comprised also as an apparatus incorporating a some function. Furthermore, in this embodiment, since it can remove and carry with a fixing tool, the function useful at the time of carrying outside a vehicle can also be provided. And the support structure (support tool) of this embodiment is the cradle 10 which hold | maintains this kind of electronic device so that attachment or detachment is possible, and fixes it on the dashboard of a vehicle.

  The cradle 10 instructs the cradle body 11 in an arbitrary posture at a predetermined position (dashboard or the like) in a vehicle interior, and a cradle body 11 that holds an electronic device body that is a substantially rectangular case (not shown). And a pedestal portion 12. In the present embodiment, the cradle body 11 is rotated with respect to the pedestal portion 12 within a predetermined angle range so that an arbitrary posture can be taken. The specific configuration is as follows.

  The pedestal portion 12 has a structure in which a hemispherical portion 12b that swells upward is provided in the center of the upper surface of a flat planar substantially rectangular substrate portion 12a. An opening 12c, which is a relatively large through hole, is formed in the center of the hemispherical portion 12b. A planar square-shaped recess 12d is formed on the lower surface of the substrate portion 12a. Moreover, the board | substrate part 12a is substantially rectangular shape substantially the same as the dimension shape of the recessed part 12d, and forms in the circular arc shape with a large curvature radius which swelled only one side a little outside. This radius of curvature is set to a value longer than the distance from the center to the apex of the recess 12d.

  A detachable fixing sheet such as a hook-and-loop fastener 14 is attached to the recess 12d. That is, the male or female hook-and-loop fastener 14 is bonded to the recess 12d, and the female or male hook-and-loop fastener paired with the male or female hook-and-loop fastener 14 is attached to a desired position such as a dashboard. Thereby, the base part 12 can be detachably fixed with respect to the dashboard on which the surface fastener is attached. Moreover, in this embodiment, in order to use an adhesive member efficiently, the shape of an adhesive member is made into the rectangular shape (In the embodiment, it may be square, but a rectangle may be sufficient.). That is, the adhesive member is usually formed by cutting out a desired size from a sheet having a larger size and shape, and when the shape of the adhesive member is made circular, a portion to be wasted from the sheet is generated. . Therefore, in this embodiment, the shape of the adhesive member is rectangular. In addition, the fixing sheet for fixing the base part 12 on a dashboard is not restricted to a hook-and-loop fastener, A gel-like adhesive sheet etc. may be sufficient.

  On the other hand, the cradle body 11 has a configuration in which a receiving portion 11b protruding forward is disposed at the lower end of an upright flat rectangular body portion 11a. As shown in FIG. It becomes a letter shape. In the center of the upper surface of the receiving portion 11b, a connector 15 is provided in an exposed state. The case of the cradle body 11 includes a front case 20 having a substantially L-shaped cross section, a rectangular rear case, and a bottom case 22 that closes below the front case 20 and the rear case 21. Composed by matching.

  Then, a spherical receiving portion 22a having an inner shape that substantially matches the outer shape of the hemispherical portion 12b is formed on the bottom case 22. Thereby, when the bottom case 22 (spherical surface receiving portion 22a) is arranged so as to cover the pedestal portion 12 (hemispherical surface portion 12b), the outer peripheral surface of the hemispherical surface portion 12b and the inner peripheral surface of the spherical surface receiving portion 22a are aligned. Both can move in an arbitrary direction along the spherical surface in contact. Therefore, assuming that the pedestal portion 12 is fixed in a horizontally placed state, the bottom case 22 and thus the cradle body 11 can be rotated 360 degrees in the horizontal plane around the apex of the hemispherical portion 12b, and in any direction The vehicle-mounted device attached to the cradle body 11 can be in a desired posture by appropriately combining the rotation and the inclination. That is, the vehicle-mounted device can be leveled or tilted by a predetermined angle in the vertical and horizontal directions. As a result, for example, even when the dashboard is tilted not horizontally in the left-right direction or the front-rear direction, the notification function such as the display screen of the in-vehicle device can be easily directed toward the driver. . From these things, it can apply suitably as a support for vehicle equipment which has a display device especially.

  The bottom case 22 (cradle body 11) and the pedestal 12 are fixed by attaching the fastener 17 from the lower surface of the hemispherical portion 12b with the spherical receiving portion 22a covered on the hemispherical portion 12b. 17 and the spherical receiving portion 22a are connected by a set screw 16, and the hemispherical portion 12b is sandwiched between the fastener 17 and the spherical receiving portion 22a with a desired force. A specific structure for performing such processing is as follows.

  First, the spherical receiving portion 22a provided in the bottom case 22 is integrally formed with a cylindrical neck portion 22b protruding upward at the apex portion of the upper surface thereof. The dimensional shape of the inner peripheral surface of the neck 22b is such that the upper part has a small diameter and a female screw part is formed on the inner peripheral surface, and the lower part has a large diameter (relative to the upper part). The flat surface is provided with a non-rotating portion.

  The fastener 17 has a base portion 17a having an outer peripheral surface coinciding with the inner peripheral surface of the hemispherical surface portion 12b of the pedestal portion 12, and a shaft portion 17b provided so as to protrude upward at the apex of the upper surface of the base portion 17a. . The shaft portion 17b is provided with two parallel detent portions 17c in parallel at predetermined positions above the outer peripheral surface thereof. Further, the fastener 17 is provided with a through-hole penetrating vertically at the center line thereof. The shaft portion 17b can be inserted into the through hole of the neck portion 22b of the spherical surface receiving portion 22a. In the inserted state, the anti-rotation portion 17c provided on the shaft portion 17b and a portion below the through hole of the neck portion 22b are provided. The rotation prevention part provided in the internal peripheral surface contacts, and the relative rotational movement of the bottom case 22 (neck part 22b) and the fastener 17 is suppressed. However, it can move in the axial direction (vertical direction). Furthermore, since the inner diameter dimension of the opening portion 21c of the pedestal portion 21 is set sufficiently larger than the outer dimension of the shaft portion 17b, the shaft portion 17b can move in the opening portion 21c. That is, in a state where the base portion 17a of the fastener 17 is in contact with the inner peripheral surface of the hemispherical portion 12b of the pedestal portion 12, the fastener 17 can be moved along the inner peripheral surface.

  Moreover, the set screw 16 is inserted into the through hole provided in the fastener 17 from below. Then, the male screw portion 16 a at the tip of the set screw 16 protrudes further upward from the upper end of the shaft 17 b of the fastener 17 and is formed on the inner peripheral surface of the upper portion of the neck portion 22 b provided on the bottom case 22. Conclude. By tightening firmly, the set screw 16 and thus the fastener 17 can be moved upward, and the distance between the upper surface of the base portion 17a of the fastener 17 and the inner peripheral surface of the spherical surface receiving portion 22a of the bottom case 22 can be reduced. . Thereby, the hemispherical surface portion 12b of the pedestal portion 12 disposed between them is sandwiched between the fastener 17 and the spherical surface receiving portion 22a with a desired pressure, and the relative movement between the pedestal portion 12 and the bottom case 22 is performed. Suppressed and fixed. On the other hand, when the set screw 16 is loosened, the tightening force with respect to the hemispherical portion 12b is weakened, and the space between the spherical receiving portions 22a can be moved along the upper surface of the hemispherical portion 12b.

  Further, since the set screw 16 is not exposed to the outside, the set screw 16 can be constituted by a metal cutting part. In the structure of Patent Document 1, it is necessary to use a composite part of a resin and a screw. However, compared with that, the configuration can be simplified and the cost can be reduced.

  And in this embodiment, the hole part 14a is formed in the center site | part of the hook_and_loop | surface fastener 14. FIG. The size of the hole is set to a size that allows the set screw 16 to be adjusted (forward / reverse rotation). By forming the hole portion 14a in this way, as shown in FIG. 5, even if the hook-and-loop fastener 14 is affixed in the recess 12d on the bottom surface of the pedestal portion 12, the set screw 16 is inserted from the hole portion 14a. Exposed. Therefore, for example, even if the hook-and-loop fastener 14 is joined to another hook-and-loop fastener already pasted on the dashboard, and the cradle body 11 is fixed on the dashboard in a predetermined posture, the hook-and-loop fastener 14 is fixed. Since the set screw 16 (screw head) is exposed by peeling it off the hook-and-loop fastener on the dashboard, the set screw 12 is loosened with a screwdriver or other tools to move the base portion 12 and the bottom case 22 relative to each other. It is possible to achieve a desired posture, and then tighten the set screw to suppress the relative movement, thereby maintaining the desired posture. Therefore, the posture can be easily changed / adjusted even after installation. Furthermore, if appropriate tightening strength (semi-fixed state) can be adjusted by moving the cradle body 11 up and down, left and right without tearing off the pair of hook-and-loop fasteners to expose the set screw, and fixing at that position. You can also.

  The hook-and-loop fastener to be attached on the dashboard may be a rectangular sheet without providing a hole or the like, or a hole may be provided in the same manner as the hook-and-loop fastener 14. However, if holes are also provided in the hook-and-loop fasteners to be mounted on the dashboard, the holes are marks so that the hook-and-loop fasteners can be easily aligned. Therefore, it is possible to suppress problems such as the mutual position when pasting is shifted, the peripheral portion of the surface fastener is exposed, and dust adheres.

  With this configuration, the spherical receiving portion 22a provided on the bottom case 22 is present in the internal space of the cradle body 11, and a female screw portion is provided on the neck portion 22b provided on the upper end of the spherical receiving portion 22a. Since the screw portion is fastened to the male screw portion 16a of the set screw 16 and fixed from the lower surface side of the pedestal portion 12 (semispherical surface portion 12b), as apparent from FIG. The distance between the lower surface of the cradle main body 11 and the upper surface of the pedestal portion 12 can be reduced as compared with the conventional ones such as Patent Document 1 and the like. The display position can be set to a low position. Therefore, it is easy for the user to see and does not interfere with the forward view during driving. Furthermore, since the adjustment screw for tightening or loosening the screw is not exposed to the outside as in Patent Document 1, the appearance is clear. Since the spherical surface portion is attached to the cradle body side, one part can be reduced as compared with the one in Patent Document 1.

  When the mounting screw portion is arranged on the side of the pedestal portion as in Patent Document 1, it is necessary to arrange the cradle main body at a position above the adjustment screw in order to avoid the adjustment screw, or to cut out the rear side of the cradle main body. Furthermore, if the mounting screw part is placed on the lower side of the main body of the electronic device (the part that is not hidden by the main body when viewed from the front), the thickness of this part will increase and the position of the display part of the electronic device main body will also be higher. However, this structure does not cause such a problem.

  That is, a ball joint mounting screw portion (a female screw portion of the neck portion 22b and a fastening portion of the 16 male screw portions 16a) of the ball joint composed of the hemispherical surface portion 12b and the spherical surface receiving portion 22a is disposed inside the cradle body 11 side, Since the mounting screw portion is arranged behind the electronic device main body to be attached to the cradle main body 11 (the portion hidden by the electronic device main body when viewed from the front), the thickness of the cradle in the state viewed from the front (the electronic device) The width of the cradle coming out at the bottom of the main body or the overall height of the cradle can be reduced.

  In addition, the cradle of the present embodiment is mounted with not only a function of holding an electronic device but also an electronic circuit / component for realizing the function of the electronic device. That is, a portable electronic device such as a navigation device functions as a normal car navigation system when it is mounted on a cradle 10 and mounted on a vehicle, and functions as a handy navigation system when it is removed from the cradle 10 and carried around the town. To do. On the other hand, it detects the microwave emitted from the vehicle speed measurement device, detects the radio wave used in the car locator system, etc., and the situation before and after the traffic accident like a drive camera. The recording function is unnecessary when the cradle 10 is removed and carried. Therefore, in the present embodiment, the electronic circuit / components used only for such unnecessary functions are mounted in the cradle body 11 so that the portable electronic device can be reduced in size and weight.

  Specifically, in this embodiment, a device related to a microwave receiver that receives microwaves is mounted on the cradle body 11. In addition, a power supply circuit is provided in the cradle body 11 so that an electronic device attached to the cradle body 11 can be charged. The connection board 24 including the connector 15 is disposed in the bottom case 22.

  At this time, the connection board 24 is provided with a concave cutout 24a cut out toward the center on one side thereof. The concave notch 24a has a shape that avoids the spherical receiving portion 12b. Accordingly, the connection substrate 24 is arranged in parallel along the bottom case 22 and does not interfere with the spherical surface receiving portion 22a, and therefore can be disposed at a position lower than the upper surface of the spherical surface receiving portion 22a. The area of the connection substrate 24 can be secured while reducing the thickness, and the dead space can be effectively used.

  The connection board 24 includes a connector 15 for connecting to the electronic device main body and a power connector 26. The power connector 26 is a connector for connecting the other end of the power cable, one end of which is connected to the cigar socket of the vehicle. The electric power supplied from the cigar socket via the power connector 26 is supplied to the electronic device main body via the circuit / connector 15 in the connection board 24. When the circuit in the electronic device main body is attached to the cradle main body 11 and operates as an on-vehicle device, the circuit operates upon receiving such power supply and charges a built-in rechargeable battery. When the battery is removed from the cradle body 11, the rechargeable battery operates as a power source.

  The main board 25 and the microwave receiving circuit board 27 are arranged upright along the rear case 21, and both the boards 25 and 27 are parallel to each other and arranged at an angle of 90 degrees with respect to the connection board 24. . Both the boards 25 and 27 or one of the boards and the connection board 24 are connected by a flexible cable 28. In the present embodiment, the flexible cable 28 is connected to the main board 25. 6 and 7 are drawn with illustration of the main board 25 omitted, the tip of the connector 28 appears to float in the air. It is connected to a connector provided on the (back side). When the flexible cable 28 is connected to one of the boards (in this embodiment, “main board 25”), the boards 25 and 27 are directly connected to each other by connection terminal pins, connection connectors, and the like. Since both the boards 25 and 27 are parallel and close to each other, they can be connected with such a simple connection structure. The microwave receiver circuit board 27 is provided with a microwave receiver (antenna) unit 29.

  When the microwave is received by the microwave receiver unit 29 / microwave receiving circuit board 27, the received signal is sent via the connection board 24 to the electronic device main body connected to the cradle main body 11, where a predetermined signal is sent. This process is performed, and an alarm accompanying microwave reception is performed. Although the microwave receiver unit 29 is used, other devices that receive radio waves and radio waves may be mounted.

  As described above, in this embodiment, the cradle serving as a support is configured to constitute a part of the in-vehicle device (electronic device). However, the present invention is not limited to this, and simply functions as a support. It may be a thing with only. On the contrary, the structure of the support of the present invention may be incorporated in the electronic device itself. That is, a spherical receiving portion 22a (neck portion 22b) that is recessed inward may be provided on the bottom surface of the electronic device.

  Moreover, when fixing an apparatus (support tool) using fixing members, such as the hook_and_loop | surface fastener 14 provided with the hole 14a like the embodiment mentioned above, it is constrained by the above-mentioned embodiment as a mechanism which adjusts the attitude | position of an apparatus.
