The invention provides a vehicle battery pack tray, a battery pack and a vehicle, the vehicle battery pack tray comprises a side wall, a bottom wall and a flange outer edge, the bottom side of the side wall surrounds the periphery of the bottom wall to form a loading space of the vehicle battery pack tray, the flange outer edge surrounds the periphery of the top side of the side wall, and the side wall, the bottom wall and the flange outer edge are made of steel plates through hot forming and stamping. A triangular face is arranged at the junction position between the corner of the side wall and the bottom wall, and when the draft angle of the side wall is 8 degrees, the draft angle of the triangular face ranges from 35 degrees to 40 degrees. When the draft angle of the side wall is 12 degrees, the draft angle of the triangular face ranges from 30 degrees to 40 degrees. The battery pack tray for the vehicle can solve the problem of contradictory relation between the forming performance and the effective volume of a traditional steel battery pack tray, it is guaranteed that the steel battery pack tray has the high effective volume, and meanwhile the good forming performance of the steel battery pack tray in the stamping process is guaranteed.

    本发明提供一种车用电池包托盘、电池包以及车辆,车用电池包托盘包括侧壁、底壁及法兰外缘,侧壁底侧围合于底壁周边以形成车用电池包托盘的装载空间,法兰外缘围合于侧壁顶侧外周,侧壁、底壁及法兰外缘采用钢板热成型冲压制成,侧壁转角与底壁之间交界位置设有三角面,当侧壁拔模角为8°时,三角面拔模角范围为35°至40°;当侧壁拔模角为12°时,三角面拔模角范围为30°至40°。该车用电池包托盘能解决传统钢制电池包托盘成形性能与有效容积之间的矛盾关系问题,既保证了钢制电池包托盘具有很高的有效容积,同时又确保了其在冲压过程中良好的成形性能。
