a central lock

Abstract

The invention discloses a central control lock, comprising a central control lock body composed of a door lock switch, a door lock actuator and a door lock controller. The outer side of the door lock actuator is fixedly connected to the interior of the door lock switch through a drive rod , the right side of the door lock actuator is fixedly connected with an electromagnetic telescopic rod through a sliding rod, the door lock switch, door lock actuator and door lock controller are all located inside the door, and the door lock actuator includes a sealing shell The invention relates to the technical field of central control locks. The central control lock can effectively solve the problem in the prior art that the traditional door lock actuator, such as the DC motor type, is connected by gears, lacks a buffer structure, has a large impact force at the moment of startup, and has a short service life of the motor ; Electromagnetic type has large power consumption, large iron core mass and impact sound when the armature moves; permanent magnet motor type has complex structure, large power consumption and easy damage.

Description

technical field [0001] The invention relates to the technical field of central control locks, in particular to a central control lock. Background technique [0002] The full name of central control lock is central control door lock, which is a kind of auto parts. At present, there are many kinds of central control locks used in automobiles, but its basic components mainly include door lock switch, door lock actuator and door lock controller. Door lock switch: Most of the central control negative switches are composed of a main switch and a sub-switch. The main switch is installed on the door next to the driver. Installed on each other car door, can control a car door independently. Door lock actuator: The central lock actuator is used to execute the driver's instruction to lock or open the door lock. The door lock actuator has three driving modes: electromagnetic type, DC motor type and permanent magnet motor type. Its structure is to execute the action of locking or open...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the above-mentioned shortcomings existing in the prior art, the present invention provides a central control lock, which can effectively solve the problems in the prior art that the traditional door lock actuator, such as the DC motor type, is connected by gears and lacks a buffer structure. In an instant, the impact force is large, and the service life of the motor is short; the electromagnetic type consumes a large amount of power, the iron core has a large mass, and there is an impact sound when the armature moves; the permanent magnet motor type has a complex structure, large power consumption, and is easily damaged. question
