To protect a high-voltage device from contact with a low-voltage device when an obstacle collides from behind a vehicle in the electric vehicle which is mounted with the high-voltage device and the low-voltage device at the rear of the vehicle.SOLUTION: In a vehicle rear structure disclosed in the present specification, a low-voltage device is located on a vehicle rear side of a high-voltage device at the same height as the high-voltage device. In addition, a cross member passes between the high-voltage device and the low-voltage device. When an obstacle collides from behind the vehicle, a collision load pushes the low-voltage device forward. However, the high-voltage device is protected by the cross member and can be prevented from contact with auxiliary devices.SELECTED DRAWING: Figure 3

    【課題】車両の後部に高電圧デバイスと低電圧デバイスを搭載する電気自動車において、車両の後方から障害物が衝突した場合、高電圧デバイスを低電圧デバイスとの接触から保護する。【解決手段】本明細書が開示する車両後部構造では、低電圧デバイスは、高電圧デバイスと同じ高さで高電圧デバイスの車両後方側に配置される。さらに、高電圧デバイスと低電圧デバイスの間にクロスメンバが通っている。車両後方から障害物が衝突した場合、衝突荷重によって低電圧デバイスは前方へ押し出される。しかし、高電圧デバイスはクロスメンバに保護され、補助デバイスとの接触を避けられる。【選択図】図3
