AI Technical Summary

Technical Problem

The user does not carry the mechanical key with him or places the mechanical key in a spare place that is inconvenient to retrieve, resulting in the problem of being unable to perform emergency unlocking.

Method used

An emergency unlocking structure is provided, including a limit plate, a lock core, a retaining ring, an unlocking structure, a rotating lock shell structure, a clutch pin and a driving member. The controller is controlled by a backup circuit, so that the driving member drives the push plate to make the first end of the clutch pin enter the limit hole for engagement. The rotating lock shell structure and the unlocking structure rotate together through the cooperation of the clutch pin to achieve emergency unlocking.

Benefits of technology

In the event of an electronic failure in the lock and the absence of a mechanical key, smooth emergency unlocking is achieved. It has a simple structure and is easy to use, which improves the user experience and ensures the safety and stability of unlocking.

Abstract

The present invention relates to the technical field of smart locks, and discloses an emergency unlocking structure and a smart lock. The emergency unlocking structure includes: a limit plate, which is provided with an installation position; a lock core, which is arranged in the installation position, and a first groove is formed on the outer wall of the lock core, and the lock core is coaxially sleeved with a retaining ring having a clutch column, and the clutch column is arranged corresponding to the first groove; an unlocking structure, which is coaxially sleeved on the lock core, and the unlocking structure is provided with a second groove corresponding to the clutch column; a rotating lock shell structure, which is coaxially sleeved on the lock core and is located in the installation position and is provided with a clutch pin, the clutch pin has a first end and a second end, and the first end is arranged corresponding to the limit hole; the retaining ring is suitable for abutting with the rotating lock shell structure; a driving member, which is power-connected with a push plate, and the push plate is arranged corresponding to the second end; a controller, which is electrically connected to the driving member; the present invention uses the controller to enable the driving member to drive the push plate so that the first end of the clutch pin enters the limit hole for cooperation, and the rotating lock shell structure is driven by external force to rotate and drive the unlocking structure to rotate together, thereby completing the emergency unlocking.
