A double lock cylinder door lock

Abstract

The technical problem to be solved by the present invention is to provide a double lock cylinder door lock, which includes a mechanical lock body and an electronically controlled lock body arranged on the door frame. The electronically controlled lock body is connected with an electronically controlled lock body drive module, and the double lock cylinder door lock also includes a fingerprint detection module, a fingerprint cabin, a switch inside the electronically controlled lock body, a control circuit unit, a data storage module, and a key input module , display module. The double lock cylinder door lock can effectively avoid the safety hazard brought by the single protection of the mechanical lock cylinder, and at the same time avoid the long-term exposure of the fingerprint recognition module to be contaminated by impurities to ensure the stability of use and prevent the fingerprint recognition module from being maliciously damaged. In addition, if the fingerprint If the control system is damaged, the user can also use the emergency mechanism to use the set verified mobile terminal to disable the electronic system of the door control system. Only the mechanical lock cylinder is used to ensure emergency use, which is convenient for users in emergency.

Description

Technical field [0001] The invention relates to a door lock device, in particular to a double lock core door lock. Background technique [0002] At present, there is an embedded fingerprint door lock with a patent number of 201320171073.8. The fingerprint door lock is equipped with a fingerprint compartment to protect the fingerprint detector from contamination or impact damage. However, it uses an external switch to protect the fingerprint detector. The fingerprint compartment can also be opened from the outside without the authorization of the owner. If it is a thief or a child playing, it may easily damage the fingerprint detection device and cause damage to the door lock. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a double-cylinder door lock. The double-cylinder door lock has the double protection effect brought by the fingerprint and mechanical double protection system in the prior art, and prevents the fingerpr...
