The invention discloses a lock shaft assembly, a locking assembly, a battery pack assembly and an electric vehicle. The lock shaft assembly comprises a mounting seat and a lock shaft, the mounting seat is connected to one end of the lock shaft, the lock shaft is mounted on the battery pack through the mounting seat, and the distances from points on the outer edge of the mounting seat to the center of the mounting seat are not completely equal in the circumferential direction of the mounting seat. The locking assembly comprises a locking mechanism and a lock shaft assembly, and the locking mechanism is used for locking and fixing the lock shaft. The battery pack assembly comprises a battery pack and a lock shaft assembly. The electric automobile comprises the battery assembly and the locking mechanism. The cross section of the mounting seat is non-circular, so that the mounting seat can be conveniently connected with the battery pack through connecting pieces such as thicker bolts or screws by increasing the size of the cross section of the mounting seat, the torque of the lock shaft assembly after the lock shaft assembly is mounted on the battery pack can be improved, and the service life of the lock shaft assembly is prolonged. And thus, the mounting reliability between the lock shaft assembly and the battery pack can be improved.

    本发明公开了一种锁轴组件、锁止组件、电池包组件及电动汽车。锁轴组件包括安装座和锁轴,安装座连接于锁轴的一端,锁轴通过安装座安装于电池包上,沿安装座的周向方向,安装座的外边缘上的各点至安装座的中心的距离不完全相等。锁止组件包括锁止机构和锁轴组件,锁止机构用于对锁轴进行锁止固定。电池包组件包括电池包和锁轴组件。电动汽车包括电池包括组件和锁止机构。安装座的横截面为非圆形的,可以较为方便地通过增大安装座的截面尺寸,从而可以通过更粗的螺栓或螺钉连接等连接件实现安装座与电池包连接,从而能够提高锁轴组件安装到电池包上后会的扭矩,进而能够提高锁轴组件与电池包之间的安装可靠性。
