The invention provides a locking assembly, a locking device and an electric vehicle, the locking assembly is installed on a girder of the electric vehicle, the locking assembly is used for being matched with a locking piece of a battery pack to lock or unlock the battery pack, the locking assembly comprises a locking mechanism and a positioning piece, the positioning piece is connected with the locking mechanism, and the locking mechanism is connected with the positioning piece. The positioning piece protrudes out of the locking mechanism in the direction close to the girder and is used for being connected with the girder in a matched mode. Positioning and fixing are carried out through the positioning piece and the modulus hole of the girder, the installation hole formed in the locking mechanism can be conveniently aligned with the modulus hole, and large installation deviation can be avoided; the connection between the positioning piece and the crossbeam can prevent the crossbeam and the locking mechanism from generating relative motion due to vibration of the electric vehicle in the driving process, the stability and reliability of the connection between the locking mechanism and the crossbeam are improved, the positioning piece can bear a certain tangential force, the tangential force borne by a bolt for connecting the locking mechanism and the crossbeam is reduced, and the service life of the locking mechanism is prolonged. Therefore, the bolt can be prevented from being cut off due to tangential force.
本发明提供一种锁止组件、锁止装置及电动车辆,其中锁止组件,安装在电动车辆的大梁上,锁止组件用于与电池包的锁止件配合以对电池包进行锁止或解锁,锁止组件包括锁止机构和定位件,定位件与锁止机构连接,且向靠近大梁的方向突出于锁止机构,定位件用于与大梁配合连接。通过定位件和大梁的模数孔进行定位和固定,方便了锁止机构上开设的安装孔与数模孔对齐,可以避免出现较大的安装偏差;定位件与大梁连接可以防止电动车辆在行驶过程中的震动使得大梁与锁止机构产生相对运动,提高了锁止机构和大梁连接的稳定性和可靠性,并且定位件可以承载一定的切向力,降低了连接锁止机构和大梁的螺栓所受的切向力,从而可以防止螺栓因切向力被剪断。
