[0051] Reference below Figures 1-23 The door lock assembly 100 according to an embodiment of the present invention is described, which realizes automatic engagement, ice breaking and electric unlocking through a drive motor 14, integrates the automatic engagement and ice breaking functions, reduces the overall volume, and thus reduces the weight of the vehicle door.

[0052] like Figures 1-23 As shown, a door lock assembly 100 according to an embodiment of the present invention includes: a mounting shell 1 , a locking assembly, a suction assembly 4 , an ice-breaking assembly, and a position rod 3 .

[0053] Among them, the mounting shell 1 is provided with a driving motor 14; the locking assembly includes a ratchet 9 and a pawl 10, which are rotatably mounted on the mounting shell 1 respectively, and the ratchet 9 is used to lock with the lock ring 200 of the vehicle door, and the pawl 10 is used to selectively lock the ratchet 9, and the ratchet 9 has a semi-locked position and a fully locked position for locking with the pawl 10; the suction assembly 4 includes a suction actuator arm 42, and the suction actuator arm 42 can be selectively connected to the ice-breaking assembly by power. The suction actuator arm 42 can be movably mounted on the mounting shell 1, and the suction actuator arm 42 has a suction position and an ice-breaking position. The suction position is a position in which the suction actuator arm 42 is powered by the ratchet 9 and can drive the ratchet 9 from the semi-locked position to the fully locked position. The ice-breaking position is a position in which the suction actuator arm 42 is disengaged from the ratchet 9 and is powered by the ice-breaking assembly, and the ratchet 9 and the pawl 10 are driven to be unlocked from the fully locked position through the ice-breaking assembly.

[0054] Moreover, the position rod 3 is suitable for pressing against the suction execution arm 42; the drive motor 14 is suitable for driving the position rod 3 to press against the suction execution arm 42 to drive the suction execution arm 42 to switch from the suction position to the ice-breaking position, and the position rod 3 is suitable for driving the pawl 10 to disengage from the ratchet 9 while moving to press against the suction execution arm 42. The drive motor 14 is suitable for pushing the suction execution arm 42 to drive the ratchet 9 from the semi-locked position to the fully locked position when the suction execution arm 42 is in the suction position, and driving the suction execution arm 42 to drive the ratchet 9 from the fully locked position to the unlocked position when the suction execution arm 42 is in the ice-breaking position.

[0055] In practice, the ratchet wheel 9 and the pawl 10 can be selectively locked or unlocked, the ratchet wheel 9 is rotatably connected to the mounting shell 1 through the ratchet wheel pin 93, and the pawl 10 is rotatably connected to the mounting shell 1 through the pawl pin 104, so that the ratchet wheel 9 and the pawl 10 can be unlocked or locked by rotating the ratchet wheel 9 or the pawl 10, and a spring can be arranged between the pawl 10 and the mounting shell 1 to facilitate the resetting of the pawl 10 after rotation; wherein the lock ring 200 is mounted on the vehicle body, and the door lock assembly 100 is mounted on the vehicle door, when the door is closed, the lock ring 200 cooperates with the ratchet wheel 9, and the ratchet wheel 9 and the pawl 10 are locked and limited, so that the lock ring 200 cannot move along the ratchet wheel 9, and the vehicle door is locked at this time.

[0056] Further, initially, the ratchet wheel 9 of the door lock assembly 100 is in an open state, and when the vehicle door is locked, the cooperation position of the ratchet wheel 9 and the pawl 10 includes a full locking position and a half locking position of the ratchet wheel 9 and the pawl 10; when the door is slightly pushed, the lock ring 200 fixed on the vehicle body hits the ratchet wheel 9 mounted on the door lock assembly 100, and pushes the ratchet wheel 9 to the half locking position, at this time, the vehicle door is not completely locked and there is a risk, so it is necessary to completely lock the vehicle door to improve the reliability of the vehicle door lock.

[0057] Specifically, the mounting shell 1 is part of the door lock assembly 100, used to support and install the structural parts inside the door lock assembly 100, and protect the structural parts of the door lock assembly 100, the driving motor 14 is installed in the mounting shell 1, and the driving motor 14 and the suction assembly 4 are power transmission; the suction assembly 4 includes a suction execution arm 42, which is rotatably connected to the mounting shell 1 through a suction arm pin 411, wherein the driving motor 14 can directly or indirectly power transmission with the suction execution arm 42, the driving motor 14 drives the suction execution arm 42 to rotate when rotating, so that the suction execution arm 42 can move to the suction position, the suction position refers to the cooperation of the suction execution arm 42 and the ratchet wheel 9, and the power transmission from the suction execution arm 42 to the ratchet wheel 9, so that the ratchet wheel 9 moves from the half locking position to the full locking position, that is, after the cooperation of the suction execution arm 42 and the ratchet wheel 9, the suction execution arm 42 drives the ratchet wheel 9 to rotate, and makes the ratchet wheel 9 rotate to cooperate with the pawl 10, and also changes the preliminary locking cooperation between the ratchet wheel 9 and the lock ring 200 to more reliable locking cooperation, that is, changes the ratchet wheel 9 from the half locking position to the full locking position.

[0058] The half-locking position is that the cooperation between the ratchet wheel 9 and the lock ring 200 is not reliable, and the door of the vehicle may be opened during driving; by rotating the suction execution arm 42 to drive the ratchet wheel 9 to cooperate with the pawl 10, and the ratchet wheel 9 and the lock ring 200 form a more reliable cooperation, that is, the ratchet wheel 9 cooperates with the lock ring 200, and the ratchet wheel 9 cooperates with the pawl 10, the lock ring 200 is located in the ratchet wheel 9 and is not easy to be separated from the ratchet wheel 9, at this time, the risk of the door being opened due to the separation of the lock ring 200 and the ratchet wheel 9 during driving of the vehicle can be reduced, that is, the cooperation position of the ratchet wheel 9 and the pawl 10 is a full-locking position.

[0059] In addition, the position rod 3 of the embodiment of the present application is power-connected to the driving motor 14, the driving motor 14 transmits power to the position rod 3 and drives the position rod 3 to move, so that the position rod 13 drives the suction execution arm 42 to move, or directly transmits power to the suction execution arm 42 to change the position of the suction execution arm 42; when driving the position rod 3 to move, the driving motor 14 changes the position of the position rod 3, and the position rod 3 can selectively abut against the suction execution arm 42, so that the movement of the position rod 3 continues to drive the position of the suction execution arm 42 to change, that is, the suction execution arm 42 is driven from the suction position to the ice-breaking position, when the suction execution arm 42 moves from the suction position to the ice-breaking position, the suction execution arm 42 is separated from the ratchet wheel 9, the suction execution arm 42 is in contact with the ice-breaking assembly, the ice-breaking assembly is power-connected to the ratchet wheel 9, and the function of the position rod 3 driving the pawl 10 to be separated from the ratchet wheel 9 to realize electric unlocking is realized, and the ice-breaking assembly can drive the ratchet wheel 9 to move from the full-locking position to the unlocking position.

[0060] That is, when the door lock assembly 100 needs to be unlocked, the door lock assembly 100 may be frozen and difficult to open due to the influence of temperature reduction, when the suction execution arm 42 is in the ice-breaking position, that is, the suction execution arm 42 can transmit power to the ratchet wheel 9 through the ice-breaking assembly to drive the ratchet wheel 9 to move from the full-locking position to the unlocking position, at this time, the unlocking means that the ratchet wheel 9 is separated from the pawl 10, and the lock ring 200 is separated from the ratchet wheel 9.

[0061] So, the same driving motor 14 can be used to realize the ice breaking operation and the change of the door lock assembly 100 from the half-locking position to the full-locking position, and the change from the full-locking position to the unlocking position during the ice breaking operation, i.e., the driving motor 14 drives the suction execution arm 42 to move to the suction position, or the driving motor 14 drives the position rod 3 to move the suction execution arm 42 to the ice breaking position, i.e., the driving motor 14 selectively powers the position rod 3 or directly powers the suction execution arm 42, realizes different functions of the same driving motor 14, integrates the automatic suction, ice breaking and electric unlocking functions, reduces the overall volume, and thus reduces the weight of the vehicle door.

[0062] Further, the pawl 10 is provided with a first locking portion 101, the ratchet wheel 9 is provided with a locking groove 92 for cooperating with the lock ring 200, one side of the locking groove 92 is provided with a second locking portion 922 and the other side is provided with a third locking portion 921; when the ratchet wheel 9 is rotated to the second locking portion 922 cooperating with the first locking portion 101, the lock ring 200 is located in the locking groove 92 and the ratchet wheel 9 and the pawl 10 are in the full-locking position, and when the ratchet wheel 9 is rotated to the third locking portion 921 cooperating with the first locking portion 101, the lock ring 200 is located in the locking groove 92 and the ratchet wheel 9 and the pawl 10 are in the half-locking position.

[0063] In practice, as shown in Figure 8 , the ratchet wheel 9 is provided with a locking groove 92, the locking groove 92 is provided with an opening, the diameter of the side of the locking groove 92 close to the opening is larger than the diameter of the side far from the opening, and when the ratchet wheel 9 and the pawl 10 are in the full-locking position, the lock ring 200 is located at the groove bottom of the locking groove 92 of the ratchet wheel 9 and is pressed against the groove bottom of the locking groove 92, at this time, the ratchet wheel 9 and the pawl 10 are limited, the diameter of the groove bottom of the locking groove 92 is smaller, so that the lock ring 200 can be reliably locked and limited.

[0064] Further, one side of the locking groove 92 is provided with a second locking portion 922 and the other side is provided with a third locking portion 921, wherein the second locking portion 922 is located at the edge of the ratchet wheel 9 and is configured as a cooperating tooth bent away from the side of the locking groove 92, and the pawl 10 is provided with a first locking portion 101, the first locking portion 101 can be a meshing surface, and the third locking portion 921 is configured as a cooperating surface located at the end of the locking groove 92, when the ratchet wheel 9 is driven by the suction execution arm 42 and moves to the full-locking position from the half-locking position, as shown in Figure 17 and 18 , the ratchet wheel 9 is in the half-locking position relative to the pawl 10, Figure 17 , and Figure 18 is the ratchet wheel 9 relative to the pawl 10 in the full-locking position, that is, from Figures 17 to 18The meshing surface cooperation between the third locking portion 921 and the pawl 10 is switched to the meshing surface cooperation between the second locking portion 922 and the pawl 10. At this time, Figures 17 to 18 That is, the counterclockwise rotation of the ratchet 9 locks the ratchet 9 and the pawl 10 , and the locking ring 200 is located at the bottom of the locking groove 92 , thereby improving the reliability of the cooperation between the ratchet 9 and the locking ring 200 .

[0065] Embodiments of the present invention Figure 17 and Figure 18 for Figure 1 The rear view, such as Figure 5 As shown, the mounting shell 1 includes a first sub-shell 11 and a second sub-shell 12. The first sub-shell 11 and the second sub-shell 12 are provided with an angle. The second sub-shell 12 is along Figure 1 The rear side of the second sub-shell 12 is connected to the ratchet 9 and the pawl 10. The ratchet 9 is rotatably connected to the second sub-shell 12 by the ratchet pin 93, and is suitable for rotating under the push of the suction execution arm 42 to change the matching relationship with the pawl 10, thereby switching from a semi-locked position to a fully locked position. In addition, referring to Figure 2 As shown, the rear side of the second sub-shell 12 is connected to the third sub-shell 13, and the third sub-shell 13 also has an angle with the first sub-shell 11. The third sub-shell 13 can provide a connection position for other structures, such as a connection position for the suction actuator arm 42.

[0066] In some embodiments, the ratchet 9 is provided with a driving arm 91, and the suction execution arm 42 and the driving arm 91 are selectively powered and suitable for driving the driving arm 91 to rotate in a first direction so that the ratchet 9 rotates in the first direction and moves from a semi-locked position to a fully locked position.

[0067] Reference Figure 8 、 Figure 17 and Figure 18 As shown, the driving arm 91 is located on the side of the ratchet 9 away from the locking groove 92. When the suction execution arm 42 is driven and rotated, the suction execution arm 42 can press against the driving arm 91, so that the ratchet 9 moves along the Figure 17 The first direction is counterclockwise, that is, Figure 1 The counterclockwise direction of the middle back view is equivalent to the clockwise direction of the front view. The ratchet 9 can change from the third locking portion 921 cooperating with the first locking portion 101 of the pawl 10 to the second locking portion 922 cooperating with the first locking portion 101 of the pawl 10. Therefore, by setting the driving arm 91, it is easy to realize the rotation of the suction execution arm 42 to drive the ratchet 9. That is, the transition from the semi-locked position to the fully locked position is the process of the ratchet 9 passing through the driving arm 91. Figures 17 to 18 status, Figure 17 That is, the lock ring 200 is located in the lock groove 92 but is not clamped to the bottom of the lock groove 92, resulting in a poor locking effect. That is, the lock ring 200 may be separated from the lock groove 92 and cause the door to open; andFigure 18 When the lock ring 200 is fully inserted into the locking groove 92, the lock ring 200 is in contact with the bottom of the locking groove 92 and is not easy to be removed from the locking groove 92.

[0068] Further, the suction execution arm 42 comprises an engaging portion 422. When the suction execution arm 42 cooperates with the driving arm 91, the engaging portion 422 of the suction execution arm 42 cooperates with the driving arm 91 of the ratchet wheel 9, thereby improving the reliability of cooperation between the ratchet wheel 9 and the suction execution arm 42, and facilitating the rotation of the driving arm 91 by the suction execution arm 42, thereby driving the ratchet wheel 9 to rotate, and facilitating the switching of the ratchet wheel 9 from the half-locking position to the full-locking position.

[0069] In some embodiments, the door lock assembly 100 further comprises an unlocking assembly, the position rod 3 is connected with the unlocking assembly, and the driving motor 14 is adapted to drive the unlocking assembly to drive the ratchet wheel 9 to be unlocked by the pawl 10 through the position rod 3.

[0070] Specifically, the driving motor 14 can drive the suction execution arm 42 to rotate, thereby driving the suction execution arm 42 to drive the position of the ratchet wheel 9 to change. At this time, there is no power transmission between the suction execution arm 42 and the position rod 3, and the unlocking assembly connected with the position rod 3 also does not move. When the electric unlocking is performed, the driving motor 14 can drive the position rod 3 to move, thereby driving the unlocking assembly to change through the movement of the position rod 3. The position change of the unlocking assembly drives the pawl 10 to move and be separated from the ratchet wheel 9. At this time, the ratchet wheel 9 and the pawl 10 are unlocked.

[0071] Therefore, through the setting of the position rod 3, the suction execution arm 42 can be selectively moved to the suction position and the ice-breaking position. When the suction execution arm 42 moves to the ice-breaking position, the pawl 10 is driven to be separated from the ratchet wheel 9 by the unlocking assembly through the position rod 3. When the ice-breaking operation of the door lock assembly 100 is performed, the pawl 10 is separated from the ratchet wheel 9. The ice-breaking operation is mainly due to the influence of the environment, and the ratchet wheel 9 cannot be rotated out. Therefore, the driving motor 14 drives the position rod 3 to achieve the separation of the pawl 10 from the ratchet wheel 9, and the position rod 3 drives the suction execution arm 42 to move to the ice-breaking position, which is convenient and time-saving.

[0072] In some embodiments, the unlocking assembly comprises an electric unlocking rocker 7 and an unlocking rocker 2; one end of the position rod 3 is connected with the unlocking rocker 2 and the other end is connected with the electric unlocking rocker 7, the unlocking rocker 2 is rotationally connected to the mounting shell 1, and the unlocking rocker 2 is power-connected with the pawl 10, the electric unlocking rocker 7 is power-connected with the driving motor 14, the driving motor 14 is adapted to rotate to drive the electric unlocking rocker 7 to move along the first side, so that the electric unlocking rocker 7 drives the position rod 3 to move along the first side, and the position rod 3 drives the unlocking rocker 2 to rotate to drive the pawl 10 to unlock the ratchet wheel 9.

[0073] As shown in Figure 1 , the driving motor 14 and the position rod 3 are power-transmitted, and the specific power transmission mode can be set according to the direction in which the position rod 3 needs to move, for example, when the driving motor 14 rotates, power can be transmitted to the electric unlocking rocker 7, and the electric unlocking rocker 7 moves towards the right side of Figure 1 , at this time, the first side is the right side, the electric unlocking rocker 7 and the position rod 3 are power-connected, and the electric unlocking rocker 7 drives the position rod 3 to move towards the right side of Figure 1 ; the position rod 3 is provided with a position rod hole 33, the position rod 3 is hingedly connected with the unlocking rocker 2 at the position rod hole 33 through a position rod pin 31, the unlocking rocker 2 is rotationally connected to the mounting shell 1 through a rocker connecting pin 21, the position rod 3 drives the unlocking rocker 2 to rotate during the movement of the position rod 3 towards the right side, the unlocking rocker 2 rotates, the position changes, and the pawl 10 can be driven to rotate, at this time, the pawl 10 can be rotated to be disengaged from the ratchet wheel 9.

[0074] Specifically, as shown in Figure 10 , the pawl 10 is provided with a connecting port 102, the pawl 10 is sleeved on a pawl pin 104 at the connecting port 102, and the pawl 10 is rotatable relative to the pawl pin 104, the pawl pin 104 is fixedly connected to the mounting shell 1, and the pawl 10 is further provided with a pressing portion 103, when the unlocking rocker 2 rotates, the pressing portion 103 of the pawl 10 can be pressed, so that the pawl 10 can rotate relative to the pawl pin 104, that is, from the perspective of Figure 22 , the pawl 10 rotates clockwise to be disengaged from the ratchet wheel 9, as shown in Figure 20 , the transverse arrow represents the movement direction of the position rod 3, the clockwise arrow of the unlocking rocker 2 represents the rotation direction of the unlocking rocker 2, Figure 20 is the position of the position rod 3 after movement, that is, in the perspective of Figure 1 , the pawl 10 needs to rotate counterclockwise, the unlocking rocker 2 rotates clockwise, and the unlocking rocker 2 comprises a rocker driving portion 22, the rocker driving portion 22 presses the pressing portion 103 of the pawl 10 to make the pawl 10 rotate along Figure 1clockwise rotation of the position lever 3, the blocking portion 35 of the position lever 3 is in contact with the driving portion 421 of the suction execution arm 42, so that the suction execution arm 42 rotates counterclockwise along the view angle of 1, changes the matching position of the suction execution arm 42 and the ratchet wheel 9, and makes the suction execution arm 42 be in the ice breaking position to drive the ratchet wheel 9 to be unlocked through the ice breaking assembly. The blocking portion 35 of the position lever 3 is configured as an arc surface, and the driving portion 421 of the suction execution arm 42 is configured as a cylindrical pin or other structures that can be in contact with the blocking portion 35 and can drive the suction execution arm 42 to rotate under the driving of the position lever 3.

[0075] In some embodiments, the outer side of the position lever 3 is provided with a blocking portion 35, the suction execution arm 42 is provided with a driving portion 421 matched with the blocking portion 35, and the position lever 3 is adapted to move along the first side, the blocking portion 35 presses against the driving portion 421 to make the suction execution arm 42 move to the ice breaking position.

[0076] In practice, when the electric unlocking is performed, the door lock assembly 100 is frozen due to the low ambient temperature, the position lever 3 moves towards the right side, the blocking portion 35 of the position lever 3 is in contact with the driving portion 421 of the suction execution arm 42, so that the suction execution arm 42 rotates counterclockwise along the view angle of 1, changes the matching position of the suction execution arm 42 and the ratchet wheel 9, and makes the suction execution arm 42 be in the ice breaking position to drive the ratchet wheel 9 to be unlocked through the ice breaking assembly. The blocking portion 35 of the position lever 3 is configured as an arc surface, and the driving portion 421 of the suction execution arm 42 is configured as a cylindrical pin or other structures that can be in contact with the blocking portion 35 and can drive the suction execution arm 42 to rotate under the driving of the position lever 3.

[0077] Therefore, by setting the blocking portion 35 and the driving portion 421 of the suction execution arm 42, the position change of the position lever 3 not only drives the unlocking assembly to move to drive the pawl 10 to be unlocked, but also drives the suction execution arm 42 to be in the ice breaking position, which is convenient to operate.

[0078] In some embodiments, the ice breaking assembly is an ice breaking rocker arm 6, the ice breaking rocker arm 6 is adapted to be in power connection with the driving arm 91, when the pawl 10 is unlocked with the ratchet wheel 9, and the suction execution arm 42 drives the driving arm 91 to rotate along the second direction through the ice breaking rocker arm 6, so that the ratchet wheel 9 rotates along the second direction and is unlocked with the pawl 10.

[0079] Referring to Figure 9 As shown in the figure, the ice breaking rocker arm 6 includes a first rod segment 61 and a second rod segment 62 connected by bending, and the ice breaking rocker arm 6 is rotationally connected to the mounting shell 1 through an ice breaking mounting pin 63, wherein the first rod segment 61 and the second rod segment 62 can be integrally formed, the top of the first rod segment 61 is provided with a matching groove 621, when the suction execution arm 42 is in the ice breaking position, the driving portion 421 of the suction execution arm 42 is matched with the matching groove 621 and drives the ice breaking rocker arm 6 to move, and the second rod segment 62 of the ice breaking rocker arm 6 is selectively in contact with the driving arm 91, when the suction execution arm 42 is in contact with the ice breaking rocker arm 6 and drives the ice breaking rocker arm 6 to move, referring to Figure 22 As shown in the figure, the suction execution arm 42 presses the ice breaking rocker arm 6, so that the ice breaking rocker arm 6 rotates counterclockwise along the view angle of Figure 22 ,Figure 22 The arrow in the figure shows the rotation direction of the icebreaking rocker 6. When the icebreaking rocker 6 rotates counterclockwise, it will contact the second driving surface 912 of the driving arm 91 of the ratchet 9 and push the driving arm 91 to rotate clockwise. At this time, the second direction is the clockwise rotation direction, that is, the ratchet 9 rotates clockwise to the unlocking direction.

[0080] When the above-mentioned suction execution arm 42 switches the ratchet 9 from the half-locking position to the full-locking position, the suction execution arm 42 directly abuts against the first driving surface 911 of the driving arm 91, that is, the suction execution arm 42 directly drives the rotation direction of the ratchet 9, and the rotation direction of the suction execution arm 42 driving the ratchet 9 through the icebreaking rocker 6 is opposite.

[0081] Therefore, by arranging the icebreaking rocker 6, the suction execution arm 42 can selectively drive the ratchet 9 through the icebreaking rocker 6 or directly drive the ratchet 9. By driving the ratchet 9 to rotate in different ways, the ratchet 9 can be switched from the half-locking position to the full-locking position or from the full-locking position to the unlocking position. The same driving motor 14 can always transmit power to the suction execution arm 42 to drive the ratchet 9 to rotate in different ways.

[0082] In some embodiments, the position rod 3 is rotationally connected with a snow load rod 8, the mounting shell 1 is provided with a meshing structure 111, and the snow load rod 8 is provided with a first clamping portion 82. When the position rod 3 moves along the first side, the position rod 3 drives the snow load rod 8 to move and makes the first clamping portion 82 mesh with the meshing structure 111, so that the position of the position rod 3 is kept fixed.

[0083] Referring to Figure 4 , the lower side of the position rod 3 is rotationally connected with the snow load rod 8 through a snow load pin 81. When the position rod 3 moves towards the right side along the direction of Figure 1 , it can drive the snow load rod 8 to move towards the right side at the same time. When the position rod 3 moves to the position, the first clamping portion 82 of the snow load rod 8 can be clamped at the position of the meshing structure 111 of the mounting shell 1. The meshing structure 111 of the mounting shell 1 is provided with a locking tooth 1111, and the first clamping portion 82 of the snow load rod 8 can be configured as an L-shaped clamping structure. The L-shaped clamping structure is clamped at the position of the locking tooth 1111, so that when the position rod 3 moves to the state that the pawl 10 is separated from the ratchet 9, the position rod 3 can be temporarily kept at the position after moving, so that the pawl 10 is kept separated from the ratchet 9. When the ratchet 9 is rotated, the door can be smoothly unlocked.

[0084] In some embodiments, the door lock assembly 100 also includes a signal rod 5, and a first elastic member is connected between the position rod 3 and the mounting shell 1. The signal rod 5 is rotationally connected to the mounting shell 1 and is powered by the ratchet 9. When the ratchet 9 and the pawl 10 are unlocked and the ratchet 9 is rotated out, the signal rod 5 drives the snow load rod 8 to unlock the engaging structure 111, and the position rod 3 is reset under the action of the first elastic member.

[0085] In practice, the signal rod 5 is rotatably connected to the mounting housing 1, and the signal rod 5 is dynamically connected to the ratchet 9. For example, the signal rod 5 is provided with a plug-in portion 52, and the ratchet 9 is provided with a connecting groove 94. The plug-in portion 52 of the signal rod 5 is connected to the connecting groove 94 of the ratchet 9. When the ratchet 9 and the pawl 10 are unlocked and rotated out, the rotation of the ratchet 9 can drive the signal rod 5 to rotate. The snow-carrying rod 8 and the position rod 3 are rotatably connected. Then, when the signal rod 5 rotates, the unlocking driving surface 51 of the signal rod 5 contacts the unlocking portion 83 of the snow-carrying rod 8, and drives the snow-carrying rod 8 to rotate during the rotation. Figure 21 As shown, the direction of the arrow is the rotation direction of the signal rod 5. When the snow load rod 8 rotates, it can be disengaged from the engaging structure 111 of the mounting shell 1. A first elastic member is provided between the position rod 3 and the mounting shell 1. The first elastic member is a spring. When the snow load rod 8 is disengaged from the engaging structure 111 of the mounting shell 1, the position rod 3 moves toward the reset direction under the action of the first elastic member. That is, the position rod 3 moves along the Figure 1 After moving toward the right, the pawl 10 is driven to disengage from the ratchet wheel 9 , and when the position lever 3 is reset, the pawl 10 is reset.

[0086] That is to say, the signal rod 5 can be associated with the rotation of the ratchet 9 through the setting of the signal rod 5, and the signal rod 5 is driven to rotate according to the rotation of the ratchet 9. The rotation of the signal rod 5 will cause the snow load rod 8 to be unlocked, so that the position rod 3 drives the pawl 10 to reset, which is convenient for controlling the position relationship between the ratchet 9 and the pawl 10 to achieve smooth rotation of the ratchet 9.

[0087] In some embodiments, the suction component 4 also includes a suction rocker arm 41, which is rotatably connected to the mounting shell 1, and the suction rocker arm 41 is dynamically connected to the suction actuator arm 42. The driving motor 14 is dynamically connected to the suction rocker arm 41 and drives the suction rocker arm 41 to rotate, so that the suction rocker arm 41 drives the suction actuator arm 42 to rotate to the suction position.

[0088] Specifically, the suction rocker arm 41 is rotatably connected to the mounting shell 1 through the suction arm pin 411, and the suction rocker arm 41 and the suction execution arm 42 are linked. For example, the suction rocker arm 41 and the suction execution arm 42 can be rotatably connected, but a pre-tightened spring is connected between the suction rocker arm 41 and the suction rocker arm 41, so that when the suction rocker arm 41 rotates, the suction execution arm 42 can be driven to rotate, or the suction rocker arm 41 and the suction execution arm 42 can be hinged.

[0089] After the driving motor 14 outputs power to the suction rocker arm 41, the initial state of the suction actuator arm 42 is Figure 15 As shown, if the rocker arm 41 is attracted along Figure 1 Rotate clockwise to drive the actuator arm 42 along Figure 1 The viewing angle rotates clockwise, that is, the suction actuator arm 42 moves along Figure 15 If the actuator arm 42 rotates counterclockwise, it can contact the driving arm 91 of the ratchet 9 and drive the ratchet 9 to rotate from the semi-locked position to the fully locked position. Figure 1 When rotating counterclockwise, the corresponding suction actuator arm 42 also moves along Figure 1 Rotate counterclockwise, that is, the actuator arm 42 is attracted along Figure 19 The initial state starts to rotate clockwise, and rotates clockwise until Figure 22 The suction actuator arm 42 contacts and cooperates with the matching groove 621 of the ice-breaking rocker arm 6. At this time, the suction actuator arm 42 is located in the ice-breaking position, so that the ice-breaking rocker arm 6 drives the ratchet 9 to unlock.

[0090] Therefore, by setting the suction rocker arm 41, the power transmission between the suction rocker arm 41 and the drive motor 14 is facilitated. At the same time, the suction rocker arm 41 can control the position change of the suction execution arm 42, and the state of the suction execution arm 42 can be switched in time.

[0091] In some embodiments, the door lock assembly 100 also includes a drive component 15, which includes a first worm 151, a first-stage worm gear 152, a second worm 153, a second-stage worm gear 154 and an output gear 155. The drive motor 14 is power-connected to the first-stage worm gear 152 through the first worm 151, the first-stage worm gear 152 is selectively power-connected to the position rod 3, the first-stage worm gear 152 is power-connected to the second-stage worm gear 154 through the second worm 153, and a non-full-circle gear 154 is provided on the side of the second-stage worm gear 154 close to the output gear 155. The non-full-circle gear 1541 is selectively power-connected to the output gear 155, and the output gear 155 is power-connected to the engaging rocker arm 41.

[0092] In practice, the output shaft of the driving motor 14 is connected to a first worm 151, which meshes with the outer side of the primary worm gear 152 and realizes power transmission. The secondary worm gear 154 is vertically connected to a second worm 153, which meshes with the outer side of the secondary worm gear 154, and the secondary worm gear 154 meshes with the output gear 155. First, when the ratchet 9 needs to be driven from the semi-locked position to the fully locked position, combined with Figure 16 and Figure 1 As shown, the direction of the arrow indicates the direction of rotation. Figure 16The first-stage worm gear 152 rotates counterclockwise, the first-stage worm gear 152 is fixedly connected with the second worm 153, so that the second worm 153 rotates counterclockwise, the second worm 153 and the meshing teeth 1542 of the second-stage worm gear 154 are arranged in a shape structure, so that the second-stage worm gear 154 rotates counterclockwise, the non-integer gear 1541 at the rear side of the second-stage worm gear 154 drives the output gear 155 to rotate clockwise, the specific design can be determined according to the shape of the meshing teeth 1542 of each gear, the output gear 155 rotates clockwise, drives the suction rocker arm 41 to rotate clockwise along the view angle of Figure 1 and Figure 16 , that is, the view angle of Figure 15 counterclockwise, so that the suction rocker arm 41 contacts the driving arm 91, thereby driving the pawl 10 from the half-locking position to the full-locking position.

[0093] When it is needed to move the suction execution arm 42 to the ice-breaking position, as shown in Figure 20 , at this time, the electric unlocking is performed, the driving motor 14 controls the first-stage worm gear 152 to rotate clockwise, and the first-stage worm gear 152 is provided with a protruding structure 1521, the protruding structure 1521 drives the electric unlocking rocker arm 7 to move towards the right side while rotating clockwise, the cutting head shown at the electric unlocking rocker arm 7 is the direction of movement towards the right side, when the electric unlocking rocker arm 7 moves towards the right side, the position rod 3 is driven to move towards the right side, that is, the pawl 10 is unlocked from the ratchet wheel 9, and the movement of the position rod 3 drives the driving part 421 of the suction execution arm 42, so that the suction execution arm 42 moves to the ice-breaking position.

[0094] It should be noted that, as shown in Figure 20 and Figure 4 , in Figure 4 , the electric unlocking rocker arm 7 is provided with a limiting part 73, and the bent end part 34 of the position rod 3 is provided with a limiting surface 341, the limiting surface 341 abuts against the limiting part 73, so that the clockwise rotation of the first-stage worm gear 152 drives the electric unlocking rocker arm 7 to move towards the right side, the electric unlocking rocker arm 7 is rotatably connected to the bent end part 34 of the position rod 3 through the electric unlocking rocker pin 71, a pre-tightening spring is arranged between the electric unlocking rocker arm 7 and the position rod 3, the electric unlocking rocker arm 7 can drive the position rod 3 to move, similar to the state that the bent end part 34 is hinged to the electric unlocking rocker arm 7, that is, the clockwise rotation of the first-stage worm gear 152 can drive the electric unlocking rocker arm 7 to move, but due to the cooperation between the limiting part 73 of the electric unlocking rocker arm 7 and the limiting surface 341 of the bent end part 34 of the position rod 3, the electric unlocking rocker arm 7 can only rotate towards one side relative to the bent end part 34, that is, the electric unlocking rocker arm 7 can rotate along Figure 20The visible angle rotates clockwise, but after the limiting portion 73 cooperates with the limiting surface 341 of the bent end portion 34 of the position rod 3, the electric unlocking rocker arm 7 cannot rotate counterclockwise relative to the bent end portion 34, and needs to move together with the position rod 3. Then, when the first-stage worm gear 152 rotates clockwise, the protruding structure 1521 of the first-stage worm gear 152 contacts the unlocking drive surface 72 of the electric unlocking rocker arm 7, and the electric unlocking rocker arm 7 can move the position rod 3 toward the right when the first-stage worm gear 152 rotates one circle clockwise, and the clockwise rotation of the first-stage worm gear 152 corresponds to electric unlocking, that is, the suction execution arm 42 is in the ice-breaking position.

[0095] Combine Figure 16 and Figure 4 As shown, when the first-stage worm gear 152 rotates counterclockwise, since a spring is provided between the electric unlocking rocker arm 7 and the bent end 34 of the position rod 3, and the electric unlocking rocker arm 7 can rotate clockwise relative to the bent end 34, the first-stage worm gear 152 rotates counterclockwise, and the protruding structure 1521 presses the electric unlocking rocker arm 7, and the electric unlocking rocker arm 7 will rotate clockwise relative to the bent end 34. Then, the electric unlocking rocker arm 7 will not drive the position rod 3 to move toward the right, but the first-stage worm gear 152 transmits power to the suction execution arm 42, causing the suction execution arm 42 to move to the suction position.

[0096] Therefore, by providing a protruding structure 1521 on the first-stage worm gear 152, and keeping the electric unlocking rocker arm 7 in active connection with the position rod 3 or selectively limiting, power transmission can be performed, and the rotation direction of the electric unlocking rocker arm 7 is limited, that is, the first-stage worm gear 152 is controlled to rotate in different directions, thereby controlling the attraction execution arm 42 to be in the attraction position or the ice-breaking position. When in the attraction position, the ratchet 9 is controlled to move from the semi-locked position to the fully locked position. When in the ice-breaking position, the ratchet 9 is controlled to move in the direction of breaking ice, that is, in the direction of unlocking. This can be achieved by a drive motor 14.

[0097] Reference Figure 13 As shown, a non-full circle gear 1541 is provided on one side of the secondary worm gear 154, and the non-full circle gear 1541 is provided with local meshing teeth 1542. When the non-full circle gear 1541 rotates to engage with the output gear 155, it can drive the output gear 155 to rotate. When the meshing teeth 1542 of the non-full circle gear 1541 rotate to disengage from the output gear 155, the rotation of the secondary worm gear 154 will not drive the rotation of the output gear 155. That is to say, when the output gear 155 is required to drive the attraction execution arm 42 to move to the attraction position, the meshing teeth 1542 of the non-full circle gear 1541 cooperate with the output gear 155. When the attraction execution arm 42 needs to be driven to the ice-breaking position through the position rod 3, the corresponding meshing teeth 1542 of the non-full circle gear 1541 are disengaged from the output gear 155. At this time, the position of the attraction execution arm 42 is controlled by the position rod 3.

[0098] Further, in the design, a movable slot 32 is arranged in the middle of the position lever 3, the output rotating shaft 1551 is connected to the mounting shell 1 through the movable slot 32, the connecting part 1552 of the output gear 155 is sleeved on the output rotating shaft 1551 and is in power connection with the suction rocker arm 41, that is, when the output gear 155 rotates, the connecting part 1552 rotates to drive the suction rocker arm 41 to rotate, and the power of the output gear 155 is transmitted to the suction rocker arm 41. Since the movable slot 32 is arranged in the middle of the position lever 3 and extends along the length direction of the position lever 3, the rotation of the output gear 155 and the movement of the position lever 3 can be independently performed.

[0099] In some embodiments, the door lock assembly 100 further comprises a second elastic member connected between the suction rocker arm 41 and the mounting shell 1 and adapted to drive the suction rocker arm 41 to reset so as to drive the suction execution arm 42 to reset when the non-integral gear 1541 is disengaged from the secondary worm gear 154.

[0100] Specifically, after the secondary worm gear 154 rotates one circle and stops, the circumferential engagement part 422 of the output gear 155 and the non-integral gear 1541 is limited, when the output gear 155 is disengaged from the non-integral gear 1541, the second elastic member can drive the suction rocker arm 41 to return to the initial position, so as to make the suction execution arm 42 return to the initial position, the second elastic member is a spring, that is, the suction execution arm 42 is driven to return to the initial position by the spring. Figures 18 to 19 Switching, the suction execution arm 42 resets to prepare for the next operation.

[0101] The embodiment of the present application also discloses a vehicle comprising the above-mentioned door lock assembly 100, which realizes automatic suction, ice breaking and electric unlocking through a driving motor 14, integrates the functions of automatic suction and ice breaking, reduces the overall volume, thereby reducing the weight of the vehicle door and improving the user experience of the vehicle.
