Fingerprint lock assembly of smart home security door

Abstract

The invention discloses a fingerprint lock assembly for an anti-theft door of a smart home. The identification glass sheet is for fingers to touch, and the identification glass sheet cooperates with a fingerprint reader to analyze and identify fingerprints by a fingerprint identification circuit. It also includes an outer pull handle and a fixed handle. The inner side of the fixed handle is fixed to the outer side of the anti-theft door when installed, and the opening at the outer end of the fixed handle is sealed by a positioning plate; the inner side of the connection part is fixed with one end of the cable of the cable assembly, and the other end of the cable is installed with the anti-theft door. The deadbolt is fixed, and one end of the jacket of the cable assembly is fixed to the inner surface of the positioning plate, and the other end of the jacket is fixed to the security door; the right side of the cable assembly is provided with an extension spring, and one end of the extension spring is connected to the inner surface of the connecting part. Fixed, the other end of the extension spring is fixed to the connecting edge of the U-shaped positioning piece. In this case, the setting of the identification glass is adjusted from a fixed type to a movable type, and from an inclined exposed type to a vertically built-in type, so as to avoid the defect that the traditional structure is easy to deposit dust.

Description

technical field [0001] The invention belongs to the field of smart home, in particular to a fingerprint lock assembly for an anti-theft door of smart home. Background technique [0002] The anti-theft door is an important facility in the home field, and it realizes anti-theft through locks. With the promotion of the concept of smart home, a fingerprint lock has appeared on the market. This fingerprint lock is located on the outer side of the anti-theft door. The distance of the fingerprint reader is calibrated at the factory. When opening the door, people's fingers directly touch the identification glass, and the fingerprint recognition circuit in the fingerprint lock recognizes the fingerprint; after the fingerprint recognition circuit recognizes the fingerprint, the fingerprint lock is unlocked, and the person turns the door handle downward by hand to open the door. In addition, for the failure of the fingerprint lock, a password identification and key identification sys...

AI Technical Summary

Problems solved by technology

[0004] 1. Since the identification glass of the fingerprint lock is inclined upward and is set toward the outside of the door, this setting method has several serious problems as follows: a. The important identification glass is exposed, which is easy to be artificially or other factors. damage, or water reaches the fingerprint identification circuit after passing through the identification glass, thereby losing the fingerprint identification circuit and causing the fingerprint lock system to fail; Reduce the success rate of fingerprint identification; moreover, people's fingers have sweat, etc., if there is too much contact, sweat will inevitably remain on the identification glass, which will further reduce the success rate of fingerprint identification; in order to avoid dust and sweat residue, people often need to use a rag Actively wipe the identification glass, but this requires an additional operation process, which is time-consuming and laborious

[0005] 2. Due to the serious defect of the above-mentioned article 1, it is currently necessary to set up a password identification and key identification system as a backup, which not only increases the complexity and volume of the lock, but also increases the manufacturing cost, which is not conducive to market promotion

[0006] 3. When unlocking the lock, first touch the identification glass with your finger, and then unlock the lock after passing the fingerprint identification, and then turn the handle to finally open the door. Two separate steps are required, and it is inconvenient to open the door
