Since the driving portion 211 is at least partially disposed in the escape recess 221, when the first turntable 21 is reset, the driving portion 211 does not contact the first stopper 222, so that the second turntable 22 is not caused to move in the reverse direction, and further, the door is locked and then unlocked.

Preferably, as shown in fig. 5-12, a second output 26 is also provided on the second turntable 22.

The relief recess 221 is located between the turntable first output 25 and the turntable second output 26.

A third push-pull wire 6 for connection to the in-door lock switch 7 is connected to the second output 26 of the rotary disk.

The second output 26 of the rotary disk is connected to the in-door lock switch 7 via a third push-pull wire 6.

By disposing the driving portion 211 at least partially in the escape recess 221, the normal unlocking and locking operation of the door lock 100 by the in-door lock switch 7 is not affected.

The driving member 3 is provided with a reset torsion spring or an expansion spring, which can drive the hinge or the movable pin to reset, and after the vehicle door is locked, the first turntable 21 is driven by the first push-pull wire 4 to reset to the initial position along with the reset of the hinge or the movable pin in the driving member 3. As shown in fig. 6, the driving section 21 includes a driving main body 212 connected to the first rotary table and a driving lever 213 connected to the driving main body 212. The driving lever 213 is connected to the driving body 212 in an L-shape. The driving lever 213 extends into the escape recess 221.

The driving body 212 and the driving rod 213 are integrally formed into an L-shaped structure, and the driving rod 213 extends towards the inside of the avoidance concave 221, so that the processing and the assembly are convenient.

The reset first turntable 21 or the first turntable 21 in the initial state has the driving lever 213 positioned in the escape recess 221, and the driving lever 213 is interposed between the first stopper 212 and the second stopper 213. At this time, the driving rod 213 does not affect the motion of the second turntable 22, the door lock switch 7 can be opened and closed, and the third push-pull wire 6 drives the second turntable 22 to rotate independently, so as to drive the second push-pull wire 5 to move, and further drive the lock swing arm 1 to rotate, so that the door lock is unlocked and locked, and the driving part 211 does not affect the independent motion of the door lock 100 by the door lock switch 7.

When the door is impacted, the drive member 3 is triggered. The output end of the driving member 3 drives the first push-pull wire 4 to move. The first push-pull wire 4 drives the first turntable 21 to rotate around the turntable rotation shaft 23, and the driving part 211 moves toward the second stopping part 223 in the escape recess 221 until contacting the second stopping part 223. Then, under the action of the driving part 211, the second turntable 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 door lock 100 to lock and lock the door. In the process, the second turntable 22 drives the door inner locking switch 7 to be closed through the third push-pull wire 6 while the door lock 100 is locked, so that secondary injury is effectively avoided, and the safety of vehicle driving is improved.

The above technical schemes can be combined according to the need to achieve the best technical effect.

The foregoing is only illustrative of the principles and preferred embodiments of the present invention. It should be noted that several other variants are possible to those skilled in the art on the basis of the principle of the invention and should also be considered as the scope of protection of the present invention.
