Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for supporting an in-vehicle device such as a vehicle radio on the vehicle body side, and more particularly to a device for mitigating a shock applied to the in-vehicle device in the event of a vehicle collision or the like.

[0002]

[Prior art]

 In a conventional vehicle, as shown in FIGS. 5 and 6, a center panel 3, a heater control 4, a center outlet 5, etc. are attached to a center console section 2 of an instrument panel 1, and a vehicle body Since the deck cross pipe 6 and the center reinforce 7, which are the connecting members with the center panel 3 and the like, are positioned relatively high in rigidity, the heavy radio 8 to be combined with the center panel 3 has both sides. When it is connected to the vehicle body side bracket 10 via the fixed bracket 9 or when the radio is attached to the vehicle body side via a bracket as in Japanese Utility Model Laid-Open No. 62-131947, When an occupant collides with the radio 8 due to inertia due to the collision, a large impact is applied to the radio 8 and the radio 8 is damaged. There is a problem.

Therefore, since the fixing bracket 9 is inserted and the screws 11 are screwed into both sides of the radio 8, the screw hole 12 formed in the fixing bracket 9 is extended to the front of the vehicle, or a normal screw hole is formed. When the large diameter portion 13 is continuously formed in front of the radio 8, and a large impact is applied to the radio 8 in the front direction, the screw 11 is displaced forward along the screw hole 12 together with the radio 8 or the screw 11 is large. The impact is mitigated by falling into the diameter portion 13. However, since the direction of the impact applied to the radio 8 is not always constant, the screw hole 12 and the large diameter portion 13 are not always fixed. The presence of the slab does not always ensure that the shock can be alleviated, and the connection between the fixing bracket 9 and the screw 8 may be loosened due to changes over time.

DISCLOSURE OF THE INVENTION The present invention is to provide a support device for an in-vehicle device that has a simple structure to reliably absorb an impact applied to the in-vehicle device and prevent the damage or the like. is there.

[0005]

[Means for Solving the Problems]

 Therefore, the supporting device for an in-vehicle device according to the present invention has a fixed bracket connected to the vehicle body side and arranged along the in-vehicle device, a hole formed in the fixed bracket, and a screw hole filled in the hole. The formed energy absorbing material and a screw that is inserted into the above-mentioned hole of the energy absorbing material and screwed into the in-vehicle device are provided, and the fixing bracket is configured to be fixed to the in-vehicle device by the screw. There is.

[0006]

[Action]

 In other words, the screw is inserted into the screw hole of the energy absorbing material and screwed into the in-vehicle device, and the energy absorbing material is arranged around the screw, so that impact is applied to the in-vehicle device from various directions. However, since the energy absorbing material absorbs the kinetic energy of the vehicle-mounted device via the vehicle that displaces together with the vehicle-mounted device in the direction of the impact, the shock received by the vehicle-mounted device can always be reliably mitigated.

[0007]

【Example】

 Hereinafter, embodiments of the present invention will be specifically described. 1 to 3, fixed brackets 21 are arranged along both sides of a radio 20 installed in a center console of a vehicle, and ribs 22 of the fixed bracket 21 bent in the vehicle width direction are attached to a vehicle body side bracket or the like. On the other hand, the fixing bracket 21 has a plurality of relatively large holes 23 formed therein, and each hole 23 is filled with an energy absorbing material 24. The fixing brackets 21 are fixed to the side surfaces of the radio 20 by inserting the screws 26 into the screw holes 25 formed in each of the Nos. 4 and screwing into the side surfaces of the radio 20, and the energy absorbing material 24 also serving as a spacer. Is a honeycomb structure made of resin or aluminum, a soft body that is deformed by a large impact, or a rubber-like elastic body. Going on.

Therefore, no matter which direction the impact is applied to the radio 20, the energy absorbing material 24 is made plastic by the screw 26 that is inserted through the screw hole 25 and is displaced together with the radio 20 in the impact direction. As the kinetic energy of the radio 20 is appropriately absorbed by the deformation or elastic deformation and its destruction, internal friction, elastic displacement, etc., as shown in the impact characteristic diagram of FIG. The impact force received by the radio 20 changes in a curve Y with respect to the curve X of the impact force received by the radio 20, and the impact can be easily mitigated. It is possible to reliably prevent damage and the like.

Further, since the screw 26 is inserted into the screw hole 25 of the energy absorbing material 24 filled in the hole portion 23 of the fixed bracket 21, the possibility that the connection between the energy absorbing material 24 and the screw 26 is loosened is small. The radio 20 can be supported at the proper position for a long period of time, and the hole 23 of the fixed bracket 21 is simply filled with the energy absorbing material 24. Therefore, no extra cost is required.

If necessary, a hard collar through which the screw is inserted may be pre-fitted in the screw hole of the energy absorbing material to secure the tightening force of the screw. It goes without saying that the same can be done when supporting devices such as a small television set installed near the center console of the vehicle in addition to the on-vehicle radio.

[0011]

[Effect of device]

 In the supporting device for an on-vehicle device according to the present invention, even if a shock is applied to the on-vehicle device from various directions, the motion of the on-vehicle device is moved by the energy absorbing material via the screw that is displaced together with the on-vehicle device in the impact direction. Since energy is absorbed, it is possible to always reliably mitigate the shock received by the in-vehicle device and easily prevent damage, etc., and suppress loosening of the connection between the fixing bracket and the screw. It can support in-vehicle equipment stably over a long period of time, and its extremely simple structure makes it practically convenient.
