[Problems to be solved by the device]

 However, in such a conventional structure, the battery bracket 12 integrally formed at the end of the battery tray 11 overlaps the front side member 7 within the range of the lap margin A. There is. Therefore, in the energy absorption process due to the crushing of the front side member 7 at the time of frontal collision, in the region of the lap margin A, the same action as the partial increase of the plate thickness of the front side member 7 is exerted. As a result, at the time when the battery bracket 12 forming the closed cross section 13 is crushed due to a frontal collision and the crushing of the lap margin A region is started next time, the energy absorption characteristics due to the crushing deformation change significantly. However, it was not possible to obtain a certain collapse-energy absorption characteristic.

The present invention has been made in view of the above conventional problems, and a battery tray support structure capable of mounting a large battery without affecting the crush-energy absorption characteristics of the front side member. It is intended to provide.

[0008]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, in the present invention, a hood ridge panel forming a side wall of an engine room is provided with a substantially horizontal shelf portion and a vertical wall hanging down from one side edge of the shelf portion. A front side member extending in the front-rear direction of the vehicle body is joined to the vertical wall, and a battery tray fixed to the shelf and extending at an end thereof onto the front side member is provided. In the battery tray support structure, the lower end of the tray is fixed to the front side member and is supported by a battery bracket standing upright. In the battery tray support structure, the battery bracket is provided with a space between the pair of leg pieces and the pair of leg pieces. It is formed into a bifurcated shape, and the lower end portion of the leg piece is fixed to the front side member.

[0009]

[Action]

 In the above structure, the battery tray has a sufficient area by extending from the ledge portion of the hood ridge panel, so that a large battery can be mounted. Further, the extended end of the battery tray is stably supported by the battery bracket having a pair of leg pieces, so that the large battery placed on the battery tray is securely supported.

On the other hand, at the time of a frontal collision, the front side member receives a load from the front side and is crushed and deformed, so that energy is absorbed. At this time, since the battery bracket has a bifurcated shape having a space between the pair of leg pieces, as the front side member is crushed and deformed, both leg pieces are close to each other while disappearing the space. Deform. Therefore, the influence of the rigidity of the battery bracket on the crush deformation of the front side member is small.

[0011]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. That is, as shown in FIG. 1, the engine room 1 provided in the front part of the vehicle body has the side wall formed by the hood ridge panel 2. The hood ridge panel 2 is provided with a substantially horizontal shelf 4 in front of the strut tower 3 provided at the rear end. An inner vertical wall 5 is vertically provided at one side edge of the shelf 4, and an outer vertical wall 6 is vertically formed at the other side edge.

A front side member 7 extending in the vehicle body front-rear direction is joined to the lower end of the inner vertical wall 5. The front side member 7 extends to the front end portion of the hood ridge panel 2, and has a vertical surface 8 and upper and lower horizontal surfaces 9 and 9 integrally provided at both end edges of the vertical surface 8. It has a substantially U-shaped cross section.

A battery tray 21 is fixed onto the shelf 4, and one end of the battery tray 21 extends to above the front side member 7. A battery 14 is placed on the battery tray 21, and both ends of a stay 15 provided laterally on the battery 14 are fixed to both sides of the battery tray 21 via bolts 16 and 16. ing.

On the other hand, the battery bracket 22 has a front leg piece 23 and a rear leg piece 24 as shown in FIG. 2, and also has a space 25 cut out in a substantially triangular shape between the two leg pieces 23, 24. It is formed in a bifurcated shape. The upper ends of the two leg pieces 23, 24 are integrated with each other to form a flange 26 that is bent in a substantially horizontal direction. The battery bracket 22 is fixed to the lower surface of the extending end portion of the battery tray 21 by a flange 26, and is fixed to the vertical surface of the front side member 7 at the lower end portions of the leg pieces 23 and 24. ing.

In the present embodiment having the above-described configuration, the battery tray 21 has a sufficient area by extending from the shelf 4 of the hood ridge panel 2, so that even a large battery 14 can be hindered. Can be placed without. Further, the extended end portion of the battery tray 21 is stably supported by the battery bracket 22 having the pair of leg pieces 23 and 24, so that the battery tray 21 has a large area and the large battery 14 is placed thereon. Even so, the bearing can be reliably supported against its weight.

On the other hand, at the time of a frontal collision, the front side member 7 receives a load from the front and is crushed and deformed rearward, so that energy is absorbed. At this time, since the battery bracket 22 has a bifurcated shape having the space 25 between the front leg piece 23 and the rear leg piece 24, both the leg pieces 23, 24 are deformed as the front side member 7 is crushed rearward and deformed. Deforms while disappearing the space 25 while approaching [FIG. 3 (a) → (b)]. Therefore, the rigidity of the battery bracket 22 has little influence on the crush deformation of the front side member 7, so that a constant crush-energy absorption characteristic is maintained in the energy absorption process due to the crush of the front side member 7 at the time of a frontal collision. Obtainable.

[0017]

[Effect of device]

 As described above, according to the present invention, the end portion of the battery tray extending from the shelf portion of the hood ridge panel onto the front side member is formed into a bifurcated shape having a pair of leg pieces and a space between the pair of leg pieces. The lower end portion of the leg piece is supported by the battery bracket fixed to the front side member. Therefore, when the front side member collapses and deforms at the time of a frontal collision, both leg pieces deform while approaching while disappearing the space, and the rigidity of the battery bracket has little effect on the collapse deformation of the front side member. Can be something. Therefore, in the energy absorption process due to the collapse of the front side member during a frontal collision, it is possible to place a large battery by extending the end of the battery tray from the shelf while obtaining a certain collapse-energy absorption characteristic. In addition, the large battery can be supported stably.
