Abstract

A vehicle body structure includes a load transmission member, a first engagement portion, and a second engagement portion. The load transmission member is disposed at a position overlapping with the power unit in a vehicle front view. The first engagement portion is provided between the load transmission member and the power unit. The second engagement portion is provided between the suspension member and the power unit.

First claim

What is claimed is:

1. A vehicle body structure, comprising:
a suspension member that is attached to a left and right pair of side members that are provided extending along a vehicle front-rear direction;
a power unit that is attached to the suspension member;
a battery unit that is disposed at a position overlapping with the power unit in a vehicle front view, and that is provided spaced apart from the power unit at an inner side in the vehicle front-rear direction with respect to the power unit;
a load transmission member that is disposed at a position overlapping with the power unit in a vehicle front view, and that is provided spaced apart from the power unit at an outer side in the vehicle front-rear direction with respect to the power unit;
a first engagement portion that is provided between the load transmission member and the power unit, and that is configured to transmit collision load to the power unit when input with collision load from the load transmission member substantially toward the vehicle front-rear direction inner side; and
a second engagement portion that is provided between the suspension member and the power unit, and that is configured to transmit collision load to the suspension member when input with collision load from the power unit substantially toward the vehicle front-rear direction inner side.

2. The vehicle body structure of claim 1 , wherein the first engagement portion and the second engagement portion are normally disposed spaced apart from the power unit.

3. The vehicle body structure of claim 1 , wherein:
the load transmission member is provided extending outward substantially in the vehicle front-rear direction from a floor cross-member, the floor cross-member coupling the left and right pair of side members together substantially in a vehicle width direction and facing the power unit; and
the first engagement portion is provided at a position at which the floor cross-member and the power unit face each other.

4. The vehicle body structure of claim 3 , wherein:
a bumper reinforcement that extends substantially along the vehicle width direction is provided at a vehicle front-rear direction outer end of the load transmission member; and
the power unit, the floor cross-member, the load transmission member, and the bumper reinforcement are disposed at positions that overlap in a vehicle front view.

5. The vehicle body structure of claim 3 , wherein:
the first engagement portion is provided at one of the floor cross-member or the power unit, and is configured projecting substantially along the vehicle front-rear direction toward the other of the floor cross-member or the power unit; and
a recess is formed in the other of the floor cross-member or the power unit at a location facing the first engagement portion such that the first engagement portion is insertable into the recess.

6. The vehicle body structure of claim 3 , wherein:
the second engagement portion is provided at one of the suspension member or the power unit, and is configured projecting substantially along the vehicle front-rear direction toward the other of the suspension member or the power unit; and
a recess is formed in the other of the suspension member or the power unit at a location facing the second engagement portion such that the second engagement portion is insertable into the recess.

7. The vehicle body structure of claim 1 , wherein the first engagement portion is configured to be displaced in substantially the vehicle front-rear direction so as to engage with the power unit when input with collision load from the load transmission member substantially toward the vehicle front-rear direction inner side.

8. The vehicle body structure of claim 1 , wherein the second engagement portion is configured to be displaced in substantially the vehicle front-rear direction so as to engage with the suspension member when input with collision load from the power unit substantially toward the vehicle front-rear direction inner side.

9. The vehicle body structure of claim 1 , wherein:
the suspension member includes a left and right pair of side rails extending along the vehicle front-rear direction, a front cross-member that couples the side rails together and that supports a vehicle front-rear direction inner side of the power unit, and a rear cross-member that couples the side rails together and that supports a vehicle front-rear direction outer side of the power unit;
the load transmission member is provided extending outward in the vehicle front-rear direction from the rear cross-member; and
the first engagement portion is provided at a position at which the rear cross-member and the power unit face each other.
