Abstract

The utility model relates to a central-control door lock for automobiles, which has the advantage of stable and safe work. The central-control door lock for automobiles comprises a control part and a mechanical part, which are connected into integration, wherein, the mechanical part comprises a lock core linking board. The door lock is also provided with a position sensor which is respectively provided with probe points corresponding to the unblocking position and the locking position of the lock core linking board and is electrically connected with a control system of the automobiles. When an automobile door is opened, a false alarm can not occur, and an antitheft alarm system of the automobiles can be turned on only after the automobile door is locked. The central-control door lock which adopts the structure has the advantages of compact structure, reliable performance, and long service life.

Description

Central control car door lock

Technical field

The utility model relates to a kind of central control car door lock.

Background technology

Existing central control car door lock generally comprises control section and mechanical part, and wherein mechanical part adopts the revotating card plank frame usually, has full lock, half lock, unlatching, safe locking and anti-error lock function; Its control section is used to refer to rotation clamp full lock, half lock and opening.This central control car door lock only has centralized Control door lock insurance, and the function of indication opening/closing door of vehicle situation and door lock safety position, does not realize being controlled by door lock the function of guard against theft and alarm system and do not have to link to each other with the control system of automobile.This moment, the guard against theft and alarm system of automobile was only controlled separately by remote controller---and open guard against theft and alarm system in the back of locking a door, and before opening the door, close guard against theft and alarm system.But when opening car door false alarm can take place sometimes by the guard against theft and alarm system that remote controller is controlled separately, work is unstable, even because guard against theft and alarm system also can be opened, be unfavorable for that the car owner in time finds the not lock state of car door, brings potential safety hazard because of carelessness easily simultaneously when the car non-locking door.

The utility model content

The purpose of this utility model is to provide at the above-mentioned shortcoming of existing central control car door lock the central control car door lock of a kind of working stability, safety, and false alarm and guard against theft and alarm system that only can opening automobile at car door locking rear can not take place when opening car door for it.

For this reason, central control car door lock of the present utility model, comprise the control section that is connected as a single entity, mechanical part, described mechanical part comprises lock core interlock plate, it is characterized in that: this door lock also is equipped with position sensor, the unlocked position and the lock position of the corresponding described lock core interlock of this position sensor plate are provided with sensing point respectively, and are electrically connected with automotive control system.

Because lock core interlock plate links to each other with door lock core, can control the release and the locking of car door door lock, when the car door door lock is in release or lockup state, be lock core interlock plate when being positioned at unlocked position or lock position, position sensor sends the different signals of telecommunication to automotive control system respectively, and the control guard against theft and alarm system disconnects or connects, thereby be implemented in when opening car door, because of lock core interlock plate is positioned at unlocked position, make guard against theft and alarm system disconnect, and effectively avoid the generation of false alarm; And when the locking car door,, make guard against theft and alarm system connect because of lock core interlock plate is positioned at the lock position, and could open guard against theft and alarm system this moment, bring potential safety hazard thereby avoid the car owner to forget the locking car door because of carelessness.Adopt centrally controrlled locking system compact conformation, dependable performance, the long service life of this structure, experiment showed, that its life-span can reach more than 100,000 times.
