An operating method of an electric actuator for a car door lock

Abstract

The invention discloses an automobile door lock electric actuator comprising a box body, as well as a motor, a worm, a first transmission gear and a second transmission gear which are mounted in the box body, wherein a power output shaft of the motor is connected with the worm, the worm is meshed with the first transmission gear, the first transmission gear is meshed with the second transmission gear, a wiring terminal is further arranged on the box body, a conducting wire is led out of the wiring terminal, one end of the conducting wire is electrically connected with an external power supply, and the other end of the conducting wire is electrically connected with the motor. An internal circuit of the automobile door lock electric actuator adopts the conducting wire for connection; compared with the prior art, the wire can be arranged arbitrarily and not constrained by space, the production process steps are simultaneously reduced, the possible short-circuit phenomena caused by poor package and incomplete die cutting during the production process can be reduced, an the stability in product quality is improved.

Description

technical field [0001] The invention relates to an automobile door lock assembly, in particular to an operation method of an electric actuator for the automobile door lock. Background technique [0002] At present, when the existing electric actuators for automobile door locks are working, the external power supply is connected to the actuator interface, and the internal transmission of the actuator is connected to the motor or the micro switch. Then perform plastic wrapping, stamping after plastic wrapping, and cut off the connection between the copper sheets. Because the gap between the copper sheets is small and the plate is relatively thin, it is easy to deform during the production process, and plastic wrapping will occur during the plastic wrapping process. The part is in place or a short circuit is formed between the copper sheet and the copper sheet, and it is easy to produce an uncut phenomenon when it is finally cut off, forming a short circuit and causing the elec...
