Abstract

Some vehicles are equipped with an onboard battery. The onboard battery includes a holding frame having a frame-shaped part, a housing case that is held by the holding frame, being inserted into the frame-shaped part, and battery modules housed in the housing case. For such a vehicle with the onboard battery, the vehicle body structure includes a displacement restricting part and a disposition depression. The displacement restricting part restricts an upward displacement of the onboard battery in a collision from behind is formed at a position facing a front end portion of the holding frame. The disposition depression is formed in a floor panel and the onboard battery is disposed to be at least partly inserted into the disposition depression.

Claims

1. A vehicle body structure for a vehicle equipped with an onboard battery, the onboard battery including a holding frame having a frame-shaped part, a housing case that is held by the holding frame, for insertion into the frame-shaped part, and battery modules housed in the housing case, the structure comprising:

a displacement restricting part that restricts an upward displacement of the onboard battery in a collision from behind is formed at a position that faces a front end portion of the holding frame; and

a disposition depression that is formed in a floor panel and into which the onboard battery is disposed to be at least partly inserted.

2. The vehicle body structure according to claim 1, wherein

the displacement restricting part is formed on a seat hinge bracket that supports a turning shaft of rear seats.

3. The vehicle body structure according to claim 1, wherein

a seat hinge bracket is fixed to a cross-member with the floor panel located between the seat hinge bracket and the cross-member, wherein the seat hinge bracket supports a turning shaft of rear seats.

4. The vehicle body structure according to claim 2, wherein

the seat hinge bracket is fixed to a cross-member with the floor panel located between the seat hinge bracket and the cross-member.

5. The vehicle body structure according to claim 1, wherein

an upper end portion of the displacement restricting part is provided with a projecting part for a restriction that projects rearward.

6. The vehicle body structure according to claim 2, wherein

an upper end portion of the displacement restricting part is provided with a projecting part for a restriction that projects rearward.

7. The vehicle body structure according to claim 3, wherein

an upper end portion of the displacement restricting part is provided with a projecting part for a restriction that projects rearward.

8. The vehicle body structure according to claim 4, wherein

an upper end portion of the displacement restricting part is provided with a projecting part for a restriction that projects rearward.

9. The vehicle body structure according to claim 1, wherein

a reinforcing member is mounted on an inner surface of a front end portion of the housing case, and

a lower end portion of the displacement restricting part is located at a same height as a height of the reinforcing member.

10. The vehicle body structure according to claim 2, wherein

a reinforcing member is mounted on an inner surface of a front end portion of the housing case, and
