  • Patent number: 11255108
    Abstract: An adaptive electric dual-controlled intelligent lock includes a mechanical clutching structure and an intelligent electronic control structure. The mechanical clutching structure includes a lock head, a lock cylinder and a lock tongue, wherein: the lock cylinder includes movable buckles, springs and a bearing. After being inserted into the keyhole of the lock head and then into the locked groove, a key is turned, the movable buckles move in an elastic range of the springs and drive the lock tongue connected with the bearing to swing, thereby realizing a mechanical unlocking process. The intelligent electronic control structure includes a PCB (printed circuit board), a motor and a shifting lever, wherein: a wireless control module is connected with an external mobile intelligent device; after the motor is started, the shifting lever pushes the movable buckles, so that the bearing drives the lock tongue to swing, thereby achieving an intelligent unlocking process.
