Description

Lock body structure with automatic locking function

Technical Field

The utility model belongs to the technical field of intelligent door locks, and relates to a lock body structure with an automatic locking function.

Background

The full-automatic intelligent door lock is a type of intelligent door lock which appears in recent years, adopts a motor as a power source, and realizes door opening and closing operation by driving a lock body to rotate through the motor. The door lock is driven by no manpower to open and close, so that the door lock can realize noninductive door entering and exiting experience, has good customer experience, and is favored by more and more customers.

The intelligent door lock is generally realized by combining two sets of systems of a control system and an actuating mechanism, wherein the control system is a core control mechanism of the door lock, and the intelligent door lock performs identity recognition on a user through sensors such as fingerprint, face recognition, a password keyboard, an IC card reader and the like so as to determine whether the door lock has door opening permission or not. The control mechanism with the door opening authority drives the executing mechanism to execute the door opening operation. The full-automatic intelligent door lock is characterized in that an executing mechanism has a full-automatic function, and the door lock is opened and closed by being driven by a motor.

The actuating mechanism of the full-automatic intelligent door lock can realize the automatic opening and closing driving of the door lock driving, but when the door lock is unlocked and when the door lock is locked, a control instruction sent by a control system is needed. The unlocking control instruction sent by the current control system is a control instruction sent by the user after the identity information of the user is obtained through the peripheral sensor and checked to be legal. However, when the lock is closed, the sensor needs to acquire a sensing signal before a locking control command can be sent.

The acquisition and judgment of the locking signal are industrial problems at present, and most control system manufacturers realize the automatic door closing of the door lock through a latch bolt mechanical mechanism in order to reduce the cost, the latch bolt of the door lock is not extended after the door is closed by the method, the safety is poor, and whether the latch bolt is locked in place or not is judged successfully or not, so that a great number of potential safety hazards are caused, and many complaints of the existing door lock are caused by the fact that the door lock is opened automatically due to the fact that the door lock is not locked reliably. Therefore, it is necessary to develop a lock body structure having an automatic locking function to realize judgment of the state of the lock tongue, thereby reliably confirming whether the door lock is closed.
