[0002] At present, the opening method of the side door lock of an automobile on the market is realized by manually operating the inner and outer door handles, that is, the door opening action is realized by manual operation; when the side door lock is closed, after the ratchet rotates to a certain angle, the pawl will catch the ratchet due to the action of the spring to achieve the locking function. This process depends on the closing force of the occupant. If the force is not enough, the door cannot be completely locked, and the occupant needs to close the door again until the door is completely locked. The traditional door lock has a single function and cannot meet the market demand under the current background of continuous intelligentization. Therefore, at present, automobile door locks with self-suction functions are more and more popular among manufacturers and users.

[0003] For the self-suction and self-unlocking of an automobile, the realization of its self-suction function depends on the control of the self-suction cable by the driver. During the self-opening process, due to freezing reasons, the ratchet of the lock body often cannot rotate in place. At this time, a corresponding ice-breaking cable needs to be set on the driver, and the ice-breaking cable is used to pull the ratchet to open the door. Therefore, it is necessary to propose a driver that cooperates with self-suction and self-unlocking and has the control functions of self-suction cable and ice-breaking cable.

[0020] The present utility model will be further described in detail below in conjunction with the drawings and embodiments, but it shall not be used as a basis for any limitation of the utility model.

[0021] Refer to the attached Figure 1 As shown, a driver for self - suction and self - unlocking of an automobile includes a housing 1, a follower rocker arm 2, a motor 3, a first gear 4, a second gear 5, a third gear 6, a cover plate 7, a self - suction wire 8 and an ice - breaking wire 9. The housing 1 and the cover plate 7 are connected by snap - fitting, and the follower rocker arm 2, the motor 3, the first gear 4, the second gear 5 and the third gear 6 are installed inside. The self - suction wire 8 and the ice - breaking wire 9 pass through the holes on the side of the housing 1. The self - suction wire 8 is connected to the third gear 6, and the ice - breaking wire 9 is connected to the follower rocker arm 2.

[0022] The following combines the attached Figure 2 , 3 The schematic diagram of the assembly process sequence to describe in detail the connection relationship and positional relationship of the above - mentioned components in the present utility model.

[0023] As Figure 2 shown, during the installation process of Process 1, the first gear 4, the follower rocker arm 2, the ice - breaking wire 9 and the motor 3 are installed in the housing 1.

[0024] Specifically, the first gear 4 is rotatably installed in the housing 1. The follower rocker arm 2 is fan - shaped and is installed in the housing 1 with its center of the circle as the rotation center. There is a connection hole on the follower rocker arm 2 for connecting with the connector at the end of the ice - breaking wire 9. During the reverse ( Figure 2 counter - clockwise direction in Figure 2 ) rotation process of the follower rocker arm 2, it drives to tighten the ice - breaking wire 9, and the other end of the ice - breaking wire 9 pulls the ratchet in the self - suction and self - unlocking device to achieve ice - breaking and unlocking of the door lock. On the housing 1, there is a limit block 101, and the limit block 101 is located on the forward (

[0025] clockwise direction in Figure 3 ) rotation path of the follower rocker arm 2 to limit the forward rotation amplitude of the follower rocker arm 2. The motor 3 is connected with a worm 301, and the motor 3 is fixed in the motor fixing groove in the housing 1.

[0026] Specifically, the second gear 5 is rotatably installed between the worm and the first gear 4. The second gear 5 is a double gear with unequal diameters and is simultaneously meshed with the worm and the first gear 4. The motor 3 drives the second gear 5 through the worm 301, and the second gear 5 drives the first gear 4 to rotate; the third gear 6 is coaxially installed with the follower rocker 2. One end face of the third gear 6 with a gear ring is provided with a stop surface 602, and the surface of the follower rocker 2 is provided with an axially protruding stop block 201. The stop surface 602 and the stop block 201 are in mating contact, which can realize the driving rotation of the third gear 6 on the follower rocker 2 during the ice-breaking process, and the follower rocker 2 is not affected by the third gear 6 during the self-priming process; the first gear 4 is a double gear with unequal diameters. While the first gear 4 is meshed with the second gear 5, it is also meshed with the third gear 6, thereby driving the third gear 6 to rotate; an arc-shaped chute 601 is provided on the other end face of the third gear 6 relative to the stop surface, and the connecting end of the self-priming cable 8 is slidably connected in the arc-shaped chute 601; when the third gear 6 rotates forward ( Figure 3 in the clockwise direction in Figure 3 ), the connecting end of the self-priming cable 8 is located at one end of the arc-shaped chute 601, the self-priming cable 8 is tightened, and the ratchet of the self-priming self-unlocking lock connected to the other end of the self-priming cable 8 is pulled, locking the car door lock, realizing the self-priming locking of the car door. At this time, the stop surface on the third gear 6 is far from the stop block 201 of the follower rocker 2, so the follower rocker 2 will not rotate and remains stationary; when the third gear 6 rotates reversely ( Figure 3 in the counterclockwise direction in Figure 3 ), the arc-shaped chute 601 slides relative to the connecting end of the self-priming cable 8, the self-priming cable 8 will not be pulled, and the stop surface 602 on the third gear 6 acts on the stop block 201 of the follower rocker 2, driving the follower rocker 2 to rotate reversely ( Figure 2 、in the counterclockwise direction in Figure 2 and 3 ), thereby tightening the ice-breaking cable 9.

[0027] The working processes of the self-priming function and the ice-breaking function of the driver described in the present invention will be described below.

[0028] The realization process of the self-priming function: The motor 3 drives the worm 301, drives the second gear 5 to rotate, drives the third gear 6 to rotate forward ( Figure 3 in the clockwise direction in Figure 3 ) through the first gear 4, tightens the self-priming cable 8, and the other end of the self-priming cable 8 pulls the ratchet in the car lock, realizing the self-priming locking of the ratchet on the car door lock; then the motor 3 reverses to the initial state.

[0029] The realization process of the ice-breaking function: The motor 3 rotates reversely, and through the transmission of the worm 301, the second gear 5, and the first gear 4, drives the third gear 6 to rotate reversely ( Figure 3 ​Rotating counterclockwise (in the counterclockwise direction in the figure), the third gear 6 pushes the follower rocker arm 2 to rotate synchronously, thereby tightening the ice-breaking wire 9. The other end of the ice-breaking wire 9 pulls the frozen ratchet wheel so that the ratchet wheel can work properly.
