In the installation process, the installation direction is adjusted according to actual needs.

When the door lock is used, one end of the rocker arm is connected with the door lock, when the door needs to be opened, a signal is sent to the transmission motor, the transmission motor drives the worm to rotate, the worm drives the worm wheel to rotate, the worm wheel drives the output gear to rotate, the output gear drives the planetary gear to rotate, the planetary gear drives the planetary carrier to rotate, the planetary carrier drives the transmission gear to rotate, the transmission gear drives the sector gear to rotate, the sector gear drives the rocker arm to swing, and the rocker arm swings to control the door lock to be opened or closed.

Because the transmission torsion spring is fixedly connected with the turbine, synchronous motion can be realized. Therefore, in the process that the worm wheel drives the output gear to rotate, the auxiliary torsion spring can do circumferential sliding in the sliding groove, but a sliding starting torque exists, when the transmission motor is electrified and unlocked, the worm wheel drives the transmission torsion spring to rotate, the transmission torsion spring contracts under the action of the auxiliary torsion spring, and the inner ring can be attached to the gear seat 27. At this time, when the transmission torsion spring provides a sufficient force, the auxiliary torsion spring starts to slide, and at the same time, the output gear 32 is driven to rotate by the friction force. Therefore, the torque of the worm gear structure is transmitted to the planetary gear set, and the subsequent movement is realized.

When the transmission motor stops to be electrified, the transmission torsion spring can be separated from the gear seat 27 under the action of self resilience force, the worm gear assembly and the planetary gear assembly are separated, no torque is transmitted, and the rocker arm 4 can realize self-resetting under the action force of the reset torsion spring 5.

After the vehicle door is opened, the gears and the rocker arms are reset and restored to the initial state under the resilience action of the transmission torsion spring, the auxiliary torsion spring and the rocker arm reset torsion spring.

The invention can also be used in cooperation with a rope in the using process, and the door lock is controlled to be opened or closed by pulling the rope.

The existing door lock basically has an automatic reset mechanism, and when a rocker arm is reset, the door lock automatically completes a lock-falling state.

The number of the planetary gears is four, and the output gear is arranged between the planetary gears.

The above is only a specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the inventive work should be included in the scope of the present invention.
