The invention discloses a quick-change battery pack and an electric automobile comprising the quick-change battery pack, the quick-change battery pack is detachably arranged on a girder of the electric automobile, the quick-change battery pack comprises a power battery and a plurality of lock connecting structures, and the lock connecting structures are evenly distributed on the periphery and/or the middle area of the power battery. The lock connecting structures extend upwards in the vertical direction, rotate by a certain angle under the action of external force and then are connected to the locking mechanism of the girder in a locked mode. The electric automobile comprises a girder and the quick-change battery pack, and the quick-change battery pack is detachably mounted on the girder. Loads are evenly distributed at all positions of the quick-change battery pack, deformation of the battery pack is effectively avoided, and the stability and anti-seismic performance of the quick-change battery pack are greatly improved. And meanwhile, the lock connecting structure moves upwards in the vertical direction and is connected to the locking mechanism in a locking manner, so that the quick disassembly or connection of the quick-change battery pack is realized.

    本发明公开了一种快换电池包及包含其的电动汽车,所述快换电池包可拆卸地设置在电动汽车的大梁上,所述快换电池包包括动力电池和若干个锁连接结构,若干个所述锁连接结构均分布于所述动力电池的周部和/或中间区域,若干个所述锁连接结构均沿竖直方向向上延伸,所述锁连接结构在外力的作用下旋转一定角度后锁止连接于所述大梁的锁止机构上。所述电动汽车包括大梁和如上所述的快换电池包,所述快换电池包可拆卸安装于所述大梁。使得载荷均匀分布在快换电池包的各处,有效避免了电池包变形,大大提高快换电池包的稳定性和抗震性能。同时,锁连接结构沿竖直方向向上移动并锁止连接于锁止机构上,实现快换电池包的快速拆卸或连接。
