Abstract

A vehicle rear-side structure is configured to ease an impact applied onto a battery pack of a vehicle upon an occurrence of a collision. The vehicle rear-side structure includes side frames and a rear-end-collision impact reducer. The side frames extend in a front-rear direction of the vehicle and are disposed at positions at which the side frames sandwich the battery pack therebetween in a widthwise direction of the vehicle. The rear-end-collision impact reducer is disposed between and above the side frames at a rear side of the battery pack. The rear-end-collision impact reducer is configured to allow air, which is to be sent to a battery stack included in the battery pack, to flow through the rear-end-collision impact reducer.

Claims (45)

1. A vehicle rear-side structure configured to ease an impact applied onto a battery pack of a vehicle upon an occurrence of a collision, the vehicle rear-side structure comprising:

side frames; and

a rear-end-collision impact reducer,

wherein the side frames extend in a front-rear direction of the vehicle and are disposed at positions at which the side frames sandwich the battery pack therebetween in a widthwise direction of the vehicle,

wherein the rear-end-collision impact reducer is disposed between and above the side frames at a rear side of the battery pack, and

wherein the rear-end-collision impact reducer is configured to allow air, which is to be sent to a battery stack included in the battery pack, to flow through the rear-end-collision impact reducer.

2. The vehicle rear-side structure according to claim 1 , wherein the rear-end-collision impact reducer has a tilt surface that is tilted upward toward a front side of the vehicle.

3. The vehicle rear-side structure according to claim 1 , wherein both sides of the rear-end-collision impact reducer are bonded to the side frames.

4. The vehicle rear-side structure according to claim 2 , wherein both sides of the rear-end-collision impact reducer are bonded to the side frames.

5. The vehicle rear-side structure according to claim 1 , wherein an upper end of the rear-end-collision impact reducer is located at a higher position than an upper end of the battery stack.

6. The vehicle rear-side structure according to claim 2 , wherein an upper end of the rear-end-collision impact reducer is located at a higher position than an upper end of the battery stack.

7. The vehicle rear-side structure according to claim 3 , wherein an upper end of the rear-end-collision impact reducer is located at a higher position than an upper end of the battery stack.

8. The vehicle rear-side structure according to claim 4 , wherein an upper end of the rear-end-collision impact reducer is located at a higher position than an upper end of the battery stack.

9. The vehicle rear-side structure according to claim 1 , further comprising;
