Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a mounting structure for electrical components for a vehicle, and more particularly to a support structure for electrical components installed in a vehicle such as an automobile.

[Conventional technology]

Recently, for vehicles such as automobiles, for example,
Various electrical components such as those described in Publication No. 194 began to be installed. Particularly, in the engine room, electrical components such as a main fuse box connected to a large number of harnesses are arranged near the engine. Such electrical components are often supported on the vehicle body side by fixed support members such as brackets.

[Problem to be solved by the invention]

Electrical components have complex internal structures and large currents flow through them, so care must be taken to ensure that they are sufficiently protected against external shocks and that the harnesses connected to them do not break or short-circuit. need to be done. However, as mentioned above, if electrical components are fixedly supported on the vehicle body, in the event of a collision, the electrical components may be damaged by the impact, or may be crushed by colliding with surrounding equipment or the vehicle body, causing the harness to collapse. There is a concern that this could lead to a short circuit. Therefore, it is desirable that electrical components be supported so as to be protected from unexpected troubles such as collisions.

[Means to solve the problem]

The present invention provides a vehicle electrical component mounting structure that supports electrical components on the vehicle body by connecting a first bracket to which the electrical components are attached and fixed to the vehicle body and a second bracket fixed to the vehicle body. Therefore, in order to solve the above problem,
While the front part of the first bracket is fixed to the vehicle body, a connecting part is provided at the rear part of the first bracket and the second bracket to connect the two brackets so that they can slide approximately back and forth.

[For production]

At the time of a collision, the first bracket moves toward the rear from the vehicle body・)f
! When the impact load is applied, the slidable connection part slides rearward with respect to the second bracket, and the first
The impact on the electrical equipment fixed to the bracket is alleviated, and damage to the electrical equipment and the harness connected to it is prevented.

[Effects of the Invention] In the vehicle electrical component mounting structure of the present invention, the front part of the first bracket to which the electrical component is attached is fixed to the vehicle body, while the rear part of the first bracket and the second bracket are fixed to the vehicle body. To,
A connecting part is provided to connect the two so that they can slide approximately back and forth.
This can reduce the impact on electrical components in the event of a collision, and can prevent damage to electrical components and the harnesses connected to them.

〔Example〕

The present invention will be described in detail below based on examples thereof.

The vehicle electrical component mounting structure shown in this embodiment is designed to prevent damage to the main fuse box and harness, which are electrical components installed in the engine room.

As shown in FIG. 3, the main fuse box I is arranged at a slightly forward position in the engine room 2, and a number of harnesses 3 are connected to it.

The engine 4 is located near the main fuse box 1.
, an air cleaner 5, etc. are arranged. In addition, in the figure, 6
is a shell upper that constitutes the front wall of the engine room 2.

As shown in FIG. 1, the main fuse box 1 has its lower portion fixed to a first bracket 7, and the front portion of the first bracket 7 is fixedly supported on the vehicle body side. on the other hand,
The rear part of the first bracket 7 overlaps the upper part of the second bracket 8 which is fixedly supported on the vehicle body side, and a connecting part 9 is formed so that the two can slide approximately in the longitudinal direction. The two brackets 7.8 are connected by the brackets 7.8.

To explain the above configuration in detail, mounting portions 1, a, and lb protruding from the lower part of the main fuse box l in the front-rear direction are fixed to the mounting flanges 7a and 7b of the first bracket 7 by fastening bolts. The front part of the first bracket 7 is fixed to a support member 10 which is fixed to the shroud upper 6 (see FIG. 3) on the vehicle body side and extends rearward by fastening bolts and nuts. On the other hand, the lower part of the second bracket 8 is fixed to the battery tray 11 fixedly supported on the vehicle body side, and the upper part is fixed to the bracket 13 fixed to the air cleaner 5 (see Fig. 3) by tightening bolts and nuts. has been done.

The slidable connection 9 provided on both brackets 7.8 is formed as follows. That is, as shown in FIG. 2, the rear lower part of the first bracket 7 has an elongated bolt insertion hole 14 that opens forward, and the upper part of the second bracket 8 has an elongated bolt insertion hole 14 that opens rearward. Insertion holes 15 are respectively formed. On the other hand, a bolt 16 is fixed through the second bracket 8 so as to correspond to the rear end position of the bolt insertion hole 14 of the first bracket 7.
A bolt 17 is passed through and fixed to the first bracket 7 so as to correspond to the bolt insertion hole 15 .

Then, both brackets 7.8 are overlapped, and bolts 16.17 inserted into these bolt insertion holes 14, 15 are fastened with nuts, thereby connecting the first bracket 7 and the second bracket 8. It looks like this.

In the vehicle electrical components configured as described above (=j structure, when a large impact external force is applied from the front, such as when a vehicle collides, electrical components are removed from the shell upper 6 via the support member 10 1 bracket 7 is subjected to a large impact load toward the rear, but bolt insertion hole 14 and bolt 1
7 move rearward with respect to the bolt 16 and the bolt insertion hole 15, respectively, and the impact is alleviated. Therefore, damage to the main fuse box 1 fixed to the first bracket 7 due to impact is avoided.

In addition, if the shroud upper 6 is significantly deformed rearward, the bolts 1 in the slidable connecting portion 9
6.17 is removed from the bolt insertion hole 14.15, and the first bracket 7 is separated from the second bracket 8. At this time, the main fuse box 1 together with the first bracket 7 is resiliently supported by the support member IO fixedly supported by the shroud upper 6, and will not fall off. and,
This prevents the main fuse box 1 from being crushed due to strong pressure from the engine 4, air cleaner 5, etc. disposed around it, and prevents the harness 3 from breaking.

By protecting the main fuse box 1 and the harness 3 from damage in this manner, short circuits can be prevented.
