Abstract: A battery assembly locking device and an automated guided vehicle comprising the battery assembly locking device. The battery assembly locking device comprises: a battery assembly (1); locking hooks (12), which are installed on the battery assembly (1); a locking member (22), which is installed on a vehicle body (3) of an automated guided vehicle; and unlocking members (13), which are installed on the battery assembly (1), wherein the battery assembly (1) is locked on the locking member (22) by means of the locking hooks (12), and is locked on the vehicle body (3) of the automated guided vehicle; and the locking hooks (12) push the locking member (22) by means of the unlocking members (13), and are unlocked from the locking member (22). By using the cooperation of the locking hooks (12) and the locking member (22) and the cooperation of the unlocking members (13) and the locking member (22), the battery assembly (1) may be locked on the vehicle body (3) of the automated guided vehicle, or the locking hooks (12) may be unlocked from the locking member (22) so that the battery assembly (1) and the vehicle body (3) of the automated guided vehicle are unlocked, thus facilitating the unlocking and disassembly of batteries, which is suitable for automated battery replacement of large batches of batteries.
