Abstract

PURPOSE:To perform sufficient absorption of collision energy by a rigidity maintaining member even when on-vehicle equipment is mounted by a method wherein a position where a first mounting member is mounted on the rigidity maintaining member is at least one spot in the vehicle advancing direction of the rigidity maintaining member. CONSTITUTION:In on-vehicle equipment mounting structure, in securing of a junction box 30, the fixing spot in a vehicle advancing direction of frame side members 12R and 12L is set as one spot. Thus, when a vehicle collides, the junction box 30 does not prevent squeeze of frame side members 12R and 12L. Thus, collision energy is sufficiently absorbed by the frame members 12R and 12L. Besides, since the junction box 30 is supported by frame side members 12R and 12L, stable mounting structure is provided.

2. Description of the Related Art Conventionally, a vehicle is provided with a rigidity maintaining member such as a frame or a side member on both sides of the vehicle to prevent bending and twisting in the front-rear direction and to absorb collision energy when the vehicle collides. It is provided in. In addition to the above-mentioned purpose, this rigidity maintaining member is also used as a supporting member when mounting various devices mounted on a vehicle.

As a structure in which a vehicle-mounted device is attached to the rigidity maintaining member, a structure for fixing a battery of an electric vehicle has been proposed (for example, Japanese Utility Model Laid-Open No. 57-13943).
1). This structure, as shown in FIG. 8A and FIG. 8B of the CC cross-sectional view, includes two support members 120 and 122 that are hung on frames 110R and 110L provided on both sides of the vehicle. A fixing member 124 for pressing and fixing the battery 130 from above is provided to fix the battery 130.

In addition to this, as shown in FIG. 8C and FIG. 8D of the sectional view taken along the line D-D, two support members 220 which are hung on side members 210R and 210L provided on both sides of the vehicle are provided. , 222 and the supporting members 220, 22

[0005]

However, the following problems occur in these structures in which the vehicle-mounted devices are mounted. In these structures, two supporting members are bridged over the rigidity maintaining members provided on both sides of the vehicle so that the vehicle-mounted device is fixed. It acts as a resistance against crushing in the vehicle traveling direction. Therefore, it becomes difficult for the rigidity maintaining member to which the two support members are attached to be crushed, and the rigidity maintaining member cannot sufficiently absorb the collision energy. This reduces the effect of the rigidity maintaining member for its original purpose.

The vehicle-mounted device mounting structure of the present invention has the following structure for the purpose of solving such problems and allowing the rigidity maintaining member to sufficiently absorb the collision energy even when the vehicle-mounted device is mounted.

[0007]

A second mounting member for mounting the vehicle-mounted device on a vehicle member other than the rigidity maintaining member, and a mounting position of the first mounting member to the rigidity maintaining member is at least a vehicle traveling direction of the rigidity maintaining member. The gist is a structure in which the vehicle-mounted device is attached as one location.

Here, in the vehicle-mounted device mounting structure, the first mounting member is bridged between the rigidity maintaining members, and the second mounting member is placed in a position parallel or twisted with the first mounting member. It is also possible to provide a structure in which the vehicle-mounted device is installed and attached. Further, in the vehicle-mounted device mounting structure, the second mounting member may be a member corresponding to a radiator support member of a vehicle including a radiator.

[0009]

In the vehicle-mounted device mounting structure of the present invention configured as described above, the mounting position of the first mounting member to the rigidity maintaining member is set to at least one position in the vehicle traveling direction of the rigidity maintaining member. By adopting the structure in which the onboard equipment is attached, the onboard equipment is preferably attached, and when the vehicle collides, the onboard equipment does not prevent the rigidity maintaining member from being crushed. As a result, the rigidity maintaining member can sufficiently absorb the collision energy.

Here, in the vehicle-mounted device mounting structure, the first mounting member is bridged between the rigidity maintaining members, and the second mounting member is mounted.
The mounting member is mounted in a position parallel or twisted with the first mounting member to mount the vehicle-mounted device, thereby facilitating the mounting of the vehicle-mounted device. Further, in the vehicle-mounted device mounting structure, the second mounting member is also used as a member corresponding to a radiator support member of a vehicle including a radiator, which contributes to reduction of the vehicle.
