DETAILED DESCRIPTION

[0026] To make the purpose, technical solutions and effects of the present application more clear and explicit, the technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0027] In view of the problem in the related art that the automatic lock body with the top and bottom hooks needs a motor to provide output force, and when the motor fails, it is difficult to use mechanical unlocking, the present application provides a lock body clutch disengagement structure and an intelligent lock. In the lock body clutch disengagement structure, the dial assembly is connected with the clutch assembly in cooperation, and the dial assembly can be driven by the rotation of the lock cylinder. The movement of the clutch assembly drives the movement of the output assembly, so that the output assembly and the motor assembly are disconnected. Therefore, when the drive motor fails, mechanical unlocking is not necessary to drive the motor to generate additional force, and the mechanical and motor drives do not interfere with each other, achieving the purpose of reducing the difficulty of mechanical unlocking, and improving the convenience of mechanical unlocking when the motor is not working. Thus, the technical problem in the related art that the automatic lock body with the top and bottom hooks needs a motor to provide output force, and when the motor fails, it is difficult to use mechanical unlocking is solved.

[0028] At present, the full-automatic lock body basically provides power on the panel by an external motor. The drive motor is arranged inside the lock body (shell), which can make the output force more efficient, but also requires a large output force to complete mechanical unlocking, resulting in difficulty in mechanical unlocking. The present application sets a suitable lock body clutch disengagement structure, so that the motor drive and the mechanical drive exist at the same time, and the motor and the mechanical drive do not interfere with each other, ensuring convenience and reliability at the same time.
