The present application discloses a reliable locking member, a battery pack assembly, and an electric vehicle. The locking member is mounted on a battery pack and used for locking the battery pack on an electric vehicle. The locking member comprises a pin shaft and a shaft sleeve. The shaft sleeve is rotatably fitted over the outer side of the pin shaft, and a lubricating space is formed between the pin shaft and the shaft sleeve. The lubricating space is formed between the pin shaft and the shaft sleeve, and when the battery pack shakes, relative rotation is generated between the shaft sleeve and the pin shaft, the contact area between the shaft sleeve and the pin shaft is reduced by the lubricating space, and thus the friction between the shaft sleeve and the pin shaft is reduced, thereby avoiding the situation that the service life is affected due to wear between the shaft sleeve and the pin shaft due to direct friction between the shaft sleeve and the pin shaft, prolonging the service life of the shaft sl
