The invention belongs to the technical field of electric vehicles, and discloses an electric vehicle battery pack quick-changing device and an electric vehicle. The electric vehicle battery pack quick-changing device comprises a vehicle body assembly; the battery assembly is arranged at the bottom of the vehicle body assembly, the battery assembly comprises a plurality of fixing sleeves, and sleeve holes are formed in the fixing sleeves; and the connecting assembly comprises a connecting sleeve, a locking pin and a locking piece, when the locking pin and the locking piece are mutually fixed, the fixing sleeve can freely move relative to the connecting sleeve in the vertical direction, the battery assembly and the vehicle body assembly are unlocked, and the battery assembly automatically falls off from the vehicle body assembly. The battery assembly has the advantages that the battery assembly is located at the bottom of the vehicle body assembly, when unlocking is needed, the elastic unit releases elastic potential energy and then moves upwards to enable the locking piece to move into the connecting sleeve, the battery assembly can automatically fall down and break away from the vehicle body assembly, a battery assembly containing space extending upwards does not need to be arranged in the vehicle body assembly, and the occupied space of the battery assembly is reduced.

    本发明属于电动汽车技术领域,公开了一种电动汽车电池包快换装置及电动汽车,电动汽车电池包快换装置包括车身总成;电池总成,设置在车身总成的底部,电池总成包括若干个固定套,固定套设有套孔;以及连接总成,包括连接套、锁止销以及锁止件,当锁止销和锁止件相互固定时,固定套可沿竖直方向相对连接套自由运动,电池总成和车身总成解锁,电池总成从车身总成上自动脱落。有益效果:电池总成位于车身总成底部,需要解锁时,弹性单元释放弹性势能后向上运动使锁止件向连接套内运动,电池总成能够自动下落,脱离车身总成,车身总成内部无需设置向上延伸的电池总成收纳空间,减小了电池总成的占用空间。
