Self-priming control method for a door lock of a motor vehicle, characterized in that it uses a self-priming and icebreaking mechanism according to any one of claims 1 to 3, comprising the following steps: the actuator pulls the self-priming rocker arm subassembly to rotate through the stay wire, the self-priming rocker arm subassembly drives the self-priming linkage arm to rotate, and a drag hook on the self-priming linkage arm pulls a protrusion on the ratchet wheel subassembly, so that the ratchet wheel subassembly slides along the pawl subassembly and pushes the pawl subassembly to rotate until the ratchet wheel subassembly moves to a full locking position, and the pawl subassembly resets and is meshed with the ratchet wheel subassembly to complete self-priming action.
5. The self-closing control method of an automobile door lock according to claim 4, wherein the self-closing linkage arm is rotated, and the first pin on the self-closing linkage arm is abutted against the guide rail on the locking bracket under the action of the return spring of the self-closing linkage arm.
6. The self-closing control method of an automobile door lock according to claim 4, wherein after the self-closing operation is completed, a reset operation is performed by the actuator, the self-sucking rocker arm sub-assembly is reset under the action of the self-sucking rocker arm return spring, and the self-sucking connecting arm is pushed to rotate around the self-sucking rocker arm shaft, and simultaneously, the self-sucking connecting arm returns to the initial position along the set route.
7. An ice breaking control method of an automobile door lock, characterized in that the method adopts the self-priming and ice breaking mechanism as claimed in any one of claims 1 to 3, and comprises the following steps: firstly, when the door lock is subjected to electric release operation, the electric release transmission mechanism pushes the sliding block to slide, the sliding block pushes the pawl sub-assembly to be separated from the ratchet wheel sub-assembly through the pawl linkage arm, and on the other hand, the sliding block adjusts the pushing arm to a track for realizing ice breaking action through the transmission of the self-suction release rocker arm and the orbital transfer rocker arm;
secondly, when the vehicle BCM judges that the vehicle door is frozen, the sliding block does not execute reset action, the actuator pulls the self-priming rocker arm sub-assembly to rotate through the pull wire, the self-priming rocker arm sub-assembly drives the pushing arm to rotate around the pushing arm shaft, meanwhile, the pushing arm moves along the sliding groove of the track-changing rocker arm through the bulge of the pushing arm, and pushes the ratchet wheel sub-assembly to rotate around the ratchet wheel linkage shaft, so that the ratchet wheel is pushed to a half locking position from a full locking position, and ice breaking action is completed.
8. The method for controlling the ice breaking of the automobile door lock according to claim 7, wherein after the ice breaking action is completed, the electric release transmission mechanism drives the sliding block to reset, and the pawl linkage arm drives the pawl subassembly to return to the full-open position of the door lock; the self-priming release rocker rotates to an initial position under the action of a self-priming release rocker return spring, and a second pin shaft on the self-priming release rocker toggles the orbit transfer rocker to rotate; the actuator releases the stay wire, the self-priming rocker arm subassembly rotates to the initial position under the action of the self-priming rocker arm return spring, and drives the self-priming connecting arm to rotate to the initial position, and after the self-priming rocker arm subassembly returns to the initial position, the ice breaking reset action is completed.
