Abstract

The invention discloses an electric actuator of a car door lock, and the electric actuator comprises a shell and a motor arranged in the shell, wherein the output shaft of the motor is connected with a worm gear; the worm gear and a transmission gear on the lower end of the worm gear are meshed; the central shaft hole of the transmission gear is fixedly connected with a screw; the transmission gear is sleeved on the screw; and threads on the screw are meshed with the internal threads of a transmission shaft. The screw of the electric actuator of the car door lock is connected with the transmission shaft by the threads. The transmission shaft is pushed and pulled by changing the current direction of the motor. The electric actuator of the car door lock has the advantages of simple structure, convenience in installation, low noise and good generality.

Description

technical field [0001] The invention relates to an electric actuator, in particular to an electric actuator for an automobile door lock. Background technique [0002] With the improvement of automobile comfort requirements, the opening of door locks is carried out by electric actuators, which are also called electric actuators; it is a driving device that can provide linear or rotary motion. Work under the action of some kind of control signal. The advantages of electric actuators are convenient energy access, fast signal transmission speed, long transmission distance, convenient centralized control, high sensitivity and precision, convenient cooperation with electric regulating instruments, simple installation and wiring, but the existing actuators can only perform A single push forward or pull back performs the function of opening the lock. An electric lock actuator capable of performing forward or reverse became a requirement. Contents of the invention [0003] The p...
