Background technique

The electric suction function is a very convenient and practical function that often appears in high-end models. However, with the development of technology and the progress of the times, it is currently showing a trend of popularization on low-end platforms. Most of the traditional self-priming back door locks are driven by large motors, or split or integrated. The main problems are high cost, large volume, and heavy weight; In the transmission mode, the open output position and the pull-in output position are set on the transmission parts of the same level, so that the output torque and speed are fixed. The electric suction lock has different requirements for torque and speed in the different actions of opening and closing; when the door is opened, it needs to respond quickly, but the torque does not need to be too large; when the door is closed and closed, Then the speed can be slowed down, but the intensity should be greater.

In view of the above, what the present application intends to provide is an electric opening and closing actuator mechanism for different requirements in the process of opening and closing the car door.
