[0054] When the driving rocker arm 3 drives the locking structure 5 and the lock tongue 2 to unlock, the rocker arm 3 can be driven to drive the snow-loading rod 7 to move, so that the snow-loading rod 7 can be moved to abut against the suction structure 6, and then the suction structure 6 can move together with the driving rocker arm 3 to drive the snow-loading rod 7. When the suction structure 6 moves to abut against the ice-breaking rocker arm 4, the ice-breaking rocker arm 4 can be driven to rotate, and then the ice-breaking rocker arm 4 can be rotated to abut against the lock tongue 2. Under the drive of the suction structure 6, the ice-breaking rocker arm 4 can drive the lock tongue 2 to rotate around the second direction, and then the unlocking assistance for the lock tongue 2 can be achieved to open the car door. The short transmission chain can improve the stability of the door lock assembly 100, and then improve the safety of the door lock assembly 100 when in use.

[0055] When the locking cam 72 is in the unlocking state, the locking cam 73 is in the unlocking state, and the locking cam 73 is in the unlocking state, so that the locking cam 73 is locked and the locking cam 73 is locked.

[0056] Among them, one of the first direction and the second direction can be set to the clockwise direction, and the other can be set to the counterclockwise direction, that is, the first direction can be set to the clockwise direction and the second direction can be set to the counterclockwise direction, or the first direction can be set to the counterclockwise direction and the second direction can be set to the clockwise direction. In this embodiment, the first direction refers to the clockwise direction, and the second direction refers to the counterclockwise direction. The special case refers to the sudden power failure after the suction structure 6 pushes the lock tongue 2 to rotate around the first direction, resulting in the suction structure 6 being unable to completely reset, and then causing the snow load rod 7 to contact the suction structure 6 prematurely under the action of the driving rocker arm 3, so that the suction structure 6 drives the ice-breaking rocker arm 4 to contact the lock tongue 2 when the car door is not unlocked, causing a closed loop condition, resulting in the lock tongue 2 being stuck.

[0057] According to the door lock assembly 100 of the embodiment of the utility model, the snow-carrying rod 7 is provided with a pushing slider 72, and the pushing slider 72 is retractable relative to the rod body 71 of the snow-carrying rod 7, so that the length of the snow-carrying rod 7 can be changed. Therefore, when the snow-carrying rod 7 contacts the suction structure 6 too early under special circumstances, the pushing slider 72 can be retracted relative to the rod body 71, thereby avoiding the situation where the lock tongue 2 is stuck, thereby improving the reliability and safety of the snow-carrying rod 7, achieving better use effect and wider application range.

[0058] In some embodiments, the rod body 71 has an installation cavity 712, which is provided with an active opening 713 open toward the suction structure 6, and the push slider 72 is suitable for extending from the active opening 713 to abut against the suction structure 6 or retracting from the active opening 713 into the installation cavity 712.

[0059] Specifically, Figure 3-Figure 5 As shown, the snow load rod 7 is provided with a rod body 71 and a pushing slider 72, and the rod body 71 is provided with a mounting cavity 712, and the mounting cavity 712 is provided with a movable opening 713, and the movable opening 713 is openly arranged toward the suction structure 6, and part of the pushing slider 72 can be arranged in the mounting cavity 712, and part can be extended to the outside of the rod body 71 through the movable opening 713, and the part of the pushing slider 72 extending out of the movable opening 713 can be pressed against the suction structure 6, and after the pushing slider 72 is acted upon by an external force, it can also be retracted into the mounting cavity 712 through the movable opening 713.

[0060] When the snow-carrying rod 7 moves toward the suction structure 6, the pushing slider 72 outside the installation cavity 712 can be pressed against the suction structure 6, thereby pushing the suction structure 6 to move; and when the suction structure 6 is stuck due to special circumstances, the suction structure 6 can act on the pushing slider 72, so that the pushing slider 72 shrinks into the installation cavity 712 to change the length of the snow-carrying rod 7, thereby avoiding the situation where the locking tongue 2 is stuck, etc., thereby improving the reliability and safety of the snow-carrying rod 7.

[0061] The rod body 71 is provided with reinforcing ribs 715 and a plurality of weight-reducing holes 714 , which can improve the lightweight of the vehicle and the structural strength of the rod body 71 , thereby extending the service life of the snow-carrying rod 7 .

[0062] In some embodiments, an elastic member 73 is disposed in the installation cavity 712 . The elastic member 73 is connected between the pushing slider 72 and the rod body 71 and is used to apply an elastic force extending from the movable opening 713 to the pushing slider 72 .

[0063] Specifically, Figure 3-Figure 5As shown, the rod body 71 is provided with a mounting cavity 712, part of the pushing slider 72 can be set in the mounting cavity 712, and part can extend out of the rod body 71 through the movable opening 713, and an elastic member 73 is provided in the mounting cavity 712, the position of the elastic member 73 in the mounting cavity 712 is relatively fixed, and the elastic member 73 is connected to the part of the pushing slider 72 placed in the mounting cavity 712, that is, the elastic member 73 is connected between the pushing slider 72 and the rod body 71, so that the elastic member 73 can apply an elastic force extending from the movable opening 713 to the pushing slider 72.

[0064] Furthermore, the portion of the pushing slider 72 extending out of the movable opening 713 can be pressed against the suction structure 6, so that the suction structure 6 has a reaction force on the pushing slider 72. When the reaction force of the suction structure 6 on the pushing slider 72 is smaller than the elastic force applied by the elastic member 73 to the pushing slider 72, the pushing slider 72 can push the suction structure 6 to move. When the reaction force of the suction structure 6 on the pushing slider 72 is greater than the elastic force applied by the elastic member 73 to the pushing slider 72, the pushing slider 72 can be retracted from the movable opening 713 to the installation cavity 712, thereby ensuring the overall operational reliability.

[0065] In some embodiments, the elastic member 73 is configured as a torsion spring, a mounting post 74 is disposed in the mounting cavity 712 , the torsion spring is sleeved on the mounting post 74 , and one end of the torsion spring presses against the inner wall of the mounting cavity 712 and the other end presses against the pushing slider 72 .

[0066] Specifically, Figure 3-Figure 5 As shown, an elastic member 73 is provided in the installation cavity 712, and the elastic member 73 can apply an elastic force extending from the movable opening 713 to the pushing slider 72, so that the pushing slider 72 can be pressed against the suction structure 6, and the elastic member 73 can be set as a torsion spring, which can reduce the installation cost. An installation column 74 is provided in the installation cavity 712, and the torsion spring can be sleeved on the installation column 74, thereby fixing the position of the torsion spring in the installation cavity 712.

[0067] Furthermore, the torsion spring is provided with two end portions, one end of which presses against the inner wall of the installation cavity 712, and the other end presses against the pushing slider 72, so that the inner wall of the installation cavity 712 and the pushing slider 72 can squeeze the torsion spring, and the torsion spring is deformed by the force, thereby generating an elastic force, and the elastic force can act on the pushing slider 72, so that the pushing slider 72 extends out from the movable opening 713, and when the reaction force applied by the suction structure 6 to the pushing slider 72 is greater than the elastic force generated by the torsion spring, the torsion spring continues to deform, and the pushing slider 72 shrinks into the installation cavity 712. The torsion spring has a simple structure and can ensure the overall operational reliability.

[0068] In some embodiments, the suction structure 6 has an initial position, and the snow-loading rod 7 is suitable for pushing the suction structure 6 to resist the ice-breaking rocker arm 4 when the suction structure 6 is in the initial position, and the snow-loading rod 7 is suitable for pressing the suction structure 6 by pushing the slider 72 when the suction structure 6 is not reset to the initial position.

[0069] Specifically, the suction structure 6 is provided with an initial position, and the suction structure 6 can move from the initial position to contact with the lock tongue 2, and then push the lock tongue 2 to rotate around the first direction. At this time, the vehicle door can be locked, and the snow load rod 7 can push the suction structure 6 to resist the ice-breaking rocker arm 4 when the suction structure 6 is in the initial position. At this time, the suction structure 6 can rotate relative to the lock body mounting plate 1 under the action of external force, and the pushing slider 72 of the snow load rod 7 extends to the outside of the rod body 71 under the elastic force of the elastic member 73, and then can be pressed against the suction structure 6, so that the pushing slider 72 can push the suction structure 6 to resist the ice-breaking rocker arm 4, and then the ice-breaking rocker arm 4 can push the lock tongue 2 that is unlocked from the locking structure 5 to rotate along the second direction, and then the unlocking assistance for the lock tongue 2 can be achieved to open the vehicle door.

[0070] Furthermore, when the suction structure 6 is in a special situation and the suction structure 6 is not reset to the initial position, the snow-carrying rod 7 can be pressed against the suction structure 6 by the pushing slider 72, so that the suction structure 6 can apply a reaction force to the pushing slider 72, and the reaction force is greater than the elastic force applied by the elastic member 73 to the pushing slider 72, thereby causing the pushing slider 72 to shrink into the mounting cavity 712 of the rod body 71 to change the length of the snow-carrying rod 7, thereby avoiding the situation where the lock tongue 2 is stuck, and improving the reliability and safety of the snow-carrying rod 7.
