Therefore, the display device 25 is arranged on the vehicle front side as compared with the conventional arrangement position indicated by the phantom line in FIG.

  Further, the display device 25 and the instrument panel 21 are joined on the device joint portion 37 side of the device bracket 33, and the instrument panel 21 is joined to the panel joint portion 38 of the device bracket 33. Here, the weak body portion 41 is not provided between the supported portion 39 and the panel joint portion 38. The front end side of the instrument panel 21 is joined to the vehicle body. Therefore, even if the weak body part 41 is provided, the instrument panel 21 and the display device 25 are stably supported.

Next, in such a support structure for a display device, an operation when a mass load M collides from the outside of the vehicle near the front end of the front window 13 and a downward load F is applied as shown in FIG. 2 will be described.
First, when a downward load F is applied, the rear end side of the engine hood 11 and the cowl 12 and the front end side of the front window 13 are deformed downward, and accordingly, the front side of the instrument panel 21 is deformed downward.
In this display device support structure, since the display device 25 is disposed on the front side of the vehicle, a downward load is applied to the front side of the instrument panel 21 and a downward load is applied to the display device 25. .

  Then, the load is applied to the weak body portion 36 of the device bracket 33, the weak body portion 36 starts to deform, the bent portions 35a and 35b are deformed, and the interval adjusting portion 36 is deformed. As a result, the device joint 37 is displaced downward, and the front side of the instrument panel 21 and the display device 25 are displaced downward. At this time, the upper plate 22 of the instrument panel 21 comes into contact with a hollow member 18 such as a duct of an air conditioner. However, since the hollow member 18 is a thin member, it is easily deformed with the displacement of the instrument panel 21. Thereby, the downward load F is absorbed by deformation of each member near the front end of the front window 13 and deformation of the support structure of the display device 25.

According to the support structure of the display device 25 as described above, when a downward load is applied to the display device 25, the weak body portion 36 is deformed and the display device 25 can be easily displaced downward. Even if a certain display device 25 is arranged close to the front end side of the front window 13, when a downward load is applied to the front side of the instrument panel 21 and the display device 25 is deformed downward, the display device 25 can also be displaced downward. Therefore, it is possible to absorb the downward load by deforming each part near the front end of the front window 13. For example, the HIC value can be reduced.
Further, the display device 25 can be mounted on the front side of the vehicle, the feeling of pressure on the occupant can be reduced, and the arrangement position of the display device 25 can be freely set, so that the instrument panel is designed. The degree of freedom is also improved.

In the support structure of the display device 25, the instrument panel 21 is joined to the device bracket 33. Therefore, the instrument panel 21 can be stably held, and the relative position between the instrument panel 21 and the display device 25 varies. The appearance quality can be improved by preventing the vibration and vibration.
In particular, the device bracket 33 includes a device joint portion 37 on one end side from the supported portion 39 and a panel joint portion 38 on the other end side, and the instrument panel 21 is joined to the cowl 12 on the front end side to form a rear shape portion. 23, the instrument panel 21 can be stably supported even if the device bracket 33 is provided with the weak body portion 41.

  Moreover, since the instrument panel 21 is joined to the equipment joint portion side of the weak body portion 36 of the equipment bracket 33, when the weak body portion 36 is deformed by receiving a downward load, the display device 25 and the instrument panel 21 are Similarly, it can be displaced downward. Therefore, the display device 25 and the instrument panel 21 can be smoothly deformed to absorb the impact without interfering with each other.

In this display device support structure, since the weak portion 36 is provided with the bent portion 35 that crosses the device bracket 33, the deformation position in the weak portion 36 can be specified as the bent portion 35, and a desired displacement amount can be easily set. Can do. Further, since only a specific position is weakened, it is not necessary to excessively reduce the rigidity of the device bracket 33, and sufficient support strength of the display device 25 and the instrument panel 21 can be ensured.
In particular, the weak body portion 36 is provided with a plurality of bent portions 35 that cross the device bracket 33, and the plurality of bent portions 35a and 35b are bent in directions opposite to each other, so that the weak body portion 36 can be deformed without difficulty. In addition, since the space adjusting portion 36 is provided between the bent portions 35a and 35b, the device joint portion 37 is made larger than the supported portion 39 by the length of the space adjusting portion 36, that is, the distance between the adjacent bent portions 35. Can be displaced.

  Further, in this display device support structure, since the device joint portion 37 is arranged in front of the supported portion 39, the position where the device joint portion 37 and the supported portion 39 are displaced forward and backward without overlapping vertically. It becomes. Therefore, when a downward load F is applied to the device joint portion 37, the weak body portion 36 can be easily deformed, and the device joint portion 37 is reliably displaced downward.

  Further, since the support bracket 31 is fixed to the instrument panel reinforcement 15 installed between the front lower pillars, the instrument panel 21 and the display device 25 can be supported sufficiently stably, and the display device 25 can be instrument panel reinforcement. Since the display device 25 is disposed in front of the display device 15, it is possible to arrange the display device 25 significantly in front of the conventional device.

The above-described embodiment can be appropriately changed within the scope of the present invention.
For example, in the above description, the support structure of the display device has been described as being deformed when a downward load F is applied. However, in the vicinity of the front end of the front window of the vehicle, for example, a cowl as described in Patent Documents 1 to 3 described above. Naturally, it is also possible to provide other shock absorbing structures on the 12 and the instrument panel 21. If it is a support structure for a display device as described above, even if it is provided in combination with another shock absorbing structure, the shock absorbing action of the other shock absorbing structure is not hindered.

  In the above-described embodiment, an example of the shape of the device bracket 33 has been described. However, as the device bracket 33, various shapes can be adopted as long as the shape includes the supported portion 39, the device joint portion 37, and the weak body portion 36. it can. For example, as shown in FIG. 4, a plate-like or rod-like material is bent at a plurality of bent portions 35, and a narrow portion 43 is provided on the bent portions 35 a and 35 b constituting the weak body portion 36 to reduce the thickness. May be used.

  In the above embodiment, the support bracket 31 has high rigidity and has been described as an example of not deforming when a downward load F is applied. However, the instrument panel 21 and the display device 25 are sufficiently connected during normal use. If the support bracket 31 can be stably supported, the support bracket 31 can also be formed to have a rigidity that can be deformed when the load F is applied. Thereby, the instrument panel 21 and the display apparatus 25 can be displaced more greatly, and the structure which can absorb a shock more largely is obtained.

In the above embodiment, the support bracket 31 is fixed to the instrument panel reinforcement 15 of the vehicle body, but may be fixed to other parts of the vehicle body.
In the above description, the support bracket 31 and the device bracket 33 are provided separately, but the support bracket 31 and the device bracket 33 may be configured integrally. For example, the supported portion 39 may be joined to the support bracket 31.
