A dust cover 8 made of corrugated cylindrical elastic rubber is also arranged at the front part of the shell 1.

The main operation mode of the automobile door lock executing device is as follows.

1. Automatic execution of

When the slide bar is required to extend, the ECU controls the motor 32 to supply power, the motor 32 rotates to drive the threaded rod 31 to rotate, the end part of the D-shaped shaft and the inner wall of the D-shaped sleeve hole generate extrusion force, and the slide bar 2 is pushed out forwards. As the second pressure-bearing end face 23 moves forward to contact the second travel switch 7, the second travel switch 7 is triggered, and the generated electric signal is fed back to the ECU to stop supplying power to the motor 32.

When the sliding rod is required to be retracted, the ECU controls the motor 32 to supply power, the motor 32 rotates reversely to drive the threaded rod 31 to rotate reversely, and the sliding rod 2 is retracted backwards under the thrust action of the elastic resetting piece 5. As the first pressure-receiving end face 22 moves rearward to contact the first travel switch 6, the first travel switch 6 is triggered, and the generated electric signal is fed back to the ECU to stop the power supply to the motor 32.

2. Manually execute

When the sliding rod 2 needs to extend, one second shifting end 412 is indirectly or directly shifted to the side rear direction, so that the corresponding first shifting end 411 swings forwards, and the first bearing end face 22 is extruded to enable the sliding rod 2 to move forwards. The torque protector 33 moves forward along with it during this process.

When the sliding rod 2 is required to be retracted, and the second shifting end 412 is released, the sliding rod 2 is retracted backwards under the thrust of the elastic restoring piece 5, and the shifting rod 41 is stopped after rotating to the limit position under the action of the restoring torsion spring.

Example 2

A door lock assembly, as shown in fig. 1 to 10, includes an automobile door lock actuator of embodiment 1, and further includes a locking assembly; the automobile door lock executing device is arranged in the automobile door body; the locking assembly comprises a swing rod 91, a pull rod 92, a pair of buckling claws 93 and a buckle plate 94 which are arranged in the door body of the vehicle door; the middle part of the swing rod 91 is hinged in the door body, and two ends of the swing rod are provided with waist-shaped holes; the front end of the sliding rod 2 is in pin joint with one waist-shaped hole of the swing rod 91; the pull rod 92 is slidably arranged in the door body, one end of the pull rod 92 is connected with the other waist-shaped Kong Xiaojie of the swing rod 91 in a pin joint manner, a pair of buckling claws 93 are connected with the other end of the pull rod 92 in a pin joint manner, and torsion springs for enabling the buckling claws 93 to open are arranged between the buckling claws 93; a horn mouth inner cavity for accommodating the buckling claw 93 is formed in the door body; a buckle plate 94 is fixed on the vehicle body, and the buckle plate 94 is provided with a buckle hole 941 for buckling the buckle claw 93.

The main operation of the door lock assembly is as follows.

The main operation of the actuator is described with reference to embodiment 1, wherein the second shifting end 412 is shifted indirectly. Specifically, when the door outer handle is pulled, the door outer handle drives the outer second pulling end 412 to move in the lateral rear direction, and when the door inner handle is pulled, the door inner handle drives the inner second pulling end 412 to move in the lateral rear direction.

When the slide bar 2 stretches out, the swing rod 91 drives the pull rod 92 to move towards the direction close to the pinch plate 94, the buckling claw 93 moves towards the outside of the bell mouth cavity, the buckling claw 93 opens under the action of the torsion spring and is separated from the buckling hole 941, and unlocking is completed.

When the slide bar 2 is retracted, the swing rod 91 drives the pull rod 92 to move in a direction away from the buckle plate 94, the buckling claw 93 moves towards the inside of the bell mouth cavity, and the buckling claw 93 buckles into the buckling hole 941 under the extrusion action of the bell mouth cavity, so that locking is realized.
