Embodiment Construction

[0040] pass below Figures 1 to 7 A specific embodiment of the present invention will be introduced.

[0041] Such as Figures 1 to 3 As shown, the two-way action mute electric door lock actuator of the present invention consists of a motor 3, a motor cover 1, and a small compound gear 6, a middle compound gear 7, a large compound gear 9, Composite gear rotating pin 8 and output arm 10 are formed. The large compound gear 9 includes an upper gear 9b and two lower shift forks 9a1, 9a2; the output arm 10 slides along its length direction, and the output arm 10 is provided with at least one for the lower shift fork to rotate and move. The card slot 10a, the outer circle of the lower shift fork is tangent to the card slot 10a; the large compound gear 9 rotates around the compound gear rotation pin 8 on the housing 11; the motor 3 is gear-connected to the large The upper gear 9b of the compound gear 9.

[0042] The small compound gear 6 includes an upper gear 6a and a lower gear...

Abstract

The invention discloses a bidirectional-movement mute electric door lock actuator which comprises a motor, a big compound gear, a compound gear rotary pin and an output arm, wherein the big compound gear, the compound gear rotary pin and the output arm are arranged in the shell and cover plate; the big compound gear comprises an upper layer gear and two lower layer shifting yokes; the output arm slides in the length direction; the output arm is provided with at least one clamping groove which is used for supporting the lower layer shifting yokes to rotate and toggle; the outer circuit of eachlower layer shifting yoke is tangent to the clamping groove; the big compound gear rotates around the compound gear rotary pin on the shell; and the gear of the motor is connected with the upper layer gear of the big compound gear in a transmission mode. The electric actuator of the invention realizes clockwise and anticlockwise rotations, achieves the goals of locking safety and unlocking safety, and does not need to return to the neutral position, thereby avoiding strange sound; and the mechanism is safe and reliable, and can realize reliable service performance in the life cycle of the automobile.

Description

technical field [0001] The invention relates to an actuator for electronically controlled door locks for vehicles, in particular to a two-way action silent electric door lock actuator which can realize electric arming and unlocking, and does not need to return to center after arming and unlocking. Background technique [0002] The electric door lock actuator is used in conjunction with the door lock, and its operation is to realize the electric locking / unlocking action of the door lock. With the continuous improvement of automobile technology, the quality and life of the mechanism are no longer the focus of many competitors, but more and more attention is paid to ergonomics such as operating sound and operating force. The same is true for the door lock, so that the door lock is required to have a low sound when it is in motion, so as to meet people's requirements for comfort. However, the original electric actuator needs to be returned to the center in order to realize the ...
