AI Technical Summary

Technical Problem

When the main lock tongue and the auxiliary lock tongue fail to completely align with the door frame holes during the closing process of the existing smart lock, the motor starts and the lock is easily damaged or stuck.

Method used

The anti-stuck smart lock body is controlled by electronic components. By adding a secondary inclined tongue and a two-way sensing inclined tongue to jointly sense the door closing action, the motor is started only after the signal is accurately reported. An inner sliding tongue and a buffer spring are provided to alleviate the failure of the door closing sensor. The inner sliding tongue slides with the lock tongue to avoid rigid contact. A pressure sensor is used to monitor the contact between the lock tongue and the door frame. An induction hinge plate and hinge slot are provided to monitor the door opening and closing action in real time.

Benefits of technology

It effectively prevents the lock from being damaged or stuck due to improper operation, reduces the risk of damage to the lock and door frame, and realizes real-time monitoring of door opening and closing actions and fault alarm.

Abstract

The present invention discloses an anti-stuck smart lock body based on electronic component control, which relates to the technical field of smart locks. The present invention includes an automatic lock body, on one side of which a plurality of main lock tongues and a secondary lock tongue are slidably mounted, an induction seat is fixedly mounted inside the automatic lock body, one side of the induction seat extends to the outside of the automatic lock body, and the secondary lock tongue and the induction seat are both provided with an outer slide groove on one side of the automatic lock body, and a two-way induction latch and a secondary latch tongue are slidably mounted inside the two outer slide grooves. By adding a secondary latch tongue, the present invention ensures that when closing the door, the switch motor is controlled to start only after the two-way induction latch tongue and the secondary latch tongue shrink and report the door closing signal and pop out into the lock hole again, so that the main lock tongue and the secondary latch tongue will only be pushed out after the door is correctly closed, effectively preventing the main lock tongue and the secondary latch tongue from pressing against the door frame, causing damage to the lock, or the lock from getting stuck under improper operation.
