The first rotary disk 21 is provided with a driving portion 211 which can contact with the second stopper 223 and push the second rotary disk 22 to rotate.

The second rotary disc 22 is further provided with a second rotary disc output end 26, and the second rotary disc output end 26 is connected with the in-door locking switch 7 through the third push-pull wire 6.

When the door is hit, the driving member 3 is triggered. The output end of the driving component 3 drives the first push-pull wire 4 to move. The first push-pull wire 4 drives the first rotating disc 21 to rotate around the rotating disc rotating shaft 23, and the driving portion 211 moves towards the second stopping portion 223 side in the avoiding concave portion 221 until contacting with the second stopping portion 223. Then, under the action of the driving part 211, the second rotary disc 22 starts to rotate and drives the second push-pull wire 5 to move, and finally drives the lock swing arm 1 to rotate, so as to trigger the vehicle door lock 100 to lock and lock the vehicle door. In the process, when the vehicle door lock 100 is locked, the second rotary disc 22 drives the locking switch 7 in the vehicle door to be closed through the third push-pull wire 6, so that secondary damage is effectively avoided, and the safety of vehicle driving is improved.

According to the needs, the above technical schemes can be combined to achieve the best technical effect.

The foregoing is considered as illustrative only of the principles and preferred embodiments of the invention. It should be noted that, for those skilled in the art, on the basis of the principle of the present invention, several other modifications can be made, and the protection scope of the present invention should be considered.
