The invention provides a locking device, a power battery bin and an electric automobile, the locking device comprises a base, a left locking buckle and a right locking buckle, the left locking buckle and the right locking buckle are rotationally arranged on the base, and a locking groove used for limiting a to-be-locked piece is formed in the opposite side faces of the left locking buckle and the right locking buckle; the end, far away from a rotating shaft, of the left locking buckle is hinged to a left driving rod, and the left driving rod is in threaded connection with a left sliding seat slidably arranged on the base; the end, far away from the rotating shaft, of the right locking buckle is hinged to a right driving rod, and the right driving rod is in threaded connection with a right sliding base slidably arranged on the base. According to the locking device, rapid and convenient opening and closing operation can be achieved by controlling the opening angle of the left locking buckle and the right locking buckle; synchronous control over the rotating process of the left locking buckle and the rotating process of the right locking buckle can be achieved, and automatic control can be conveniently achieved through a control system. When the power is removed, the left locking buckle and the right locking buckle can still be kept in the locking state through friction self-locking, and it is guaranteed that the locking mechanism works reliably.

    本发明提供一种锁紧装置、动力电池仓与电动汽车,其中,锁紧装置包括底座和在底座上转动设置的左锁紧扣与右锁紧扣,左锁紧扣与右锁紧扣相对的侧面形成用于限位待锁紧件的锁紧槽;左锁紧扣在距离其转轴的远端与左驱动杆铰接,左驱动杆与底座上滑动设置的左滑座螺纹连接;右锁紧扣在距离其转轴的远端与右驱动杆铰接,右驱动杆与底座上滑动设置的右滑座螺纹连接。该锁紧装置可以通过控制左锁紧扣与右锁紧扣的张开角度实现快速便捷的开合作业;可以实现对左锁紧扣与右锁紧扣的转动过程的同步控制,方便经控制系统实现自动控制。卸去动力,通过摩擦自锁仍能使左锁紧扣与右锁紧扣在锁止状态下保持,保证锁止机构工作可靠。
