The invention provides a locking piece, a locking assembly, a locking device and a battery pack bracket, the locking piece is installed on a battery pack and used for locking the battery pack on an electric vehicle, the locking piece comprises a locking body, a fixing piece and a limiting piece, the fixing piece is arranged at the end of the locking body in a sleeving mode and is in threaded connection with the locking body, and the fixing piece is provided with a limiting matching part; the limiting piece penetrates through the locking body in the radial direction of the locking body and is used for being matched with the limiting matching part to prevent the fixing piece from rotating. The limiting piece arranged in the radial direction is matched with the limiting matching part of the fixing piece so as to avoid loosening and falling caused by rotation of the fixing piece, the stability of the locking piece when the battery pack is locked to the electric vehicle can be improved, and the fixing piece can be prevented from loosening due to bumping of the electric vehicle through matching of the limiting piece and the limiting matching part; the limiting piece is arranged in the radial direction of the locking body so that the axial limiting capacity of the locking body can be improved, the limiting piece is not prone to failure when subjected to axial impact force, and the locking effect of the locking piece is improved.

    本发明提供一种锁止件、锁止组件、锁止装置和电池包托架,锁止件安装于电池包并用于将电池包锁止于电动车辆,锁止件包括锁止本体、固定件和限位件,固定件套设于锁止本体的端部并与锁止本体螺纹连接,固定件设有限位匹配部;限位件沿锁止本体的径向穿过锁止本体并用于与限位匹配部配合以防止固定件转动。径向设置的限位件与固定件的限位匹配部相配合以避免固定件转动而导致松动、掉落,也就有利于提高锁止件将电池包锁止于电动车辆时的稳定性,限位件和限位匹配部的配合能够避免固定件因电动车辆的颠簸而松动;限位件沿锁止本体的径向设置能够提高其轴向的限位能力,当受到轴向的冲击力时限位件不容易失效,提高了锁止件的锁止效果。
