Fingerprint coded lock body

Abstract

The invention discloses a fingerprint coded lock body, belongs to the field of locks, and solves the problem that the lock cannot keep the normal work of a coded lock when the motor is damaged due toonly one motor in the prior art. The technical scheme is characterized by comprising a shell body and a main sliding plate which is arranged inside the shell body in a sliding manner in the width direction of the shell body, wherein lock bolts which can extend out of the shell body is arranged on the main sliding plate; a first elastic piece which drives the lock bolts to slide out of the shell body is arranged on the shell body; a pull plate which slides synchronously with the main slide plate is connected to the main sliding plate; through grooves are formed in the pull plate in the width direction of the shell body, sliding blocks are arranged in the through grooves in a sliding manner; motors for driving the sliding blocks to slide back and forth are arranged in the shell body; at least two groups of the motors, the sliding blocks and the through grooves are formed. During normal operation, one group of the motors works normally, and the rest motors are in standby state, when one group of motors are damaged, the motors in standby state are started, and the pull plate can still be pulled to drive the lock bolt to retreat, so that the normal use of the coded lock is ensured.

Description

technical field [0001] The invention relates to a lock, in particular to a fingerprint combination lock body. Background technique [0002] With the popularization of technology and the development of smart home, more and more people begin to choose fingerprint locks. Fingerprint locks are a kind of smart locks, which are the perfect crystallization of computer information technology, electronic technology, mechanical technology and modern hardware technology. It is convenient, fast and accurate. [0003] The utility model patent with the notification number CN207392935U provides a combination lock body. There is no keyhole on the surface of the lock body, which gets rid of the dependence on traditional keys, improves the security of the lock itself and broadens the application range of the lock. [0004] The combination lock body in the prior art mainly uses the motor as the power output. Although the transmission structure is different, the power source is a motor. Throug...

AI Technical Summary

Problems solved by technology

[0004] The combination lock body in the prior art mainly uses the motor as the power output. Although the transmission structure is different, the power source is a motor. Through the rotation of the motor shaft and the action of the relevant transmission structure, the sliding of the dead bolt is finally realized. It is the connection device between electronics and machinery in the combination lock, and the center of power conversion, which plays an important role in linking the past and the future. If the motor stops working or is blocked, the lock will automatically open or cannot be locked, which is not very safe.
