For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

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

[0052] like Figure 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 and 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, the ratchet 9 is used to lock with the lock ring 200 of the vehicle door, 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, 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, the suction actuator arm 42 has a suction position and an ice-breaking position, the suction position is a position where 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 where 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 unlock from the fully locked position through the ice-breaking assembly.

[0054] Moreover, the position rod 3 is suitable for pressing against the suction actuator arm 42; the drive motor 14 is suitable for driving the position rod 3 to press against the suction actuator arm 42 to drive the suction actuator 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 actuator arm 42, and the drive motor 14 is suitable for pushing the suction actuator arm 42 to drive the ratchet 9 to move from the semi-locked position to the fully locked position when the suction actuator arm 42 is in the suction position, and driving the suction actuator arm 42 to drive the ratchet 9 to move from the fully locked position to the unlocked position when the suction actuator arm 42 is in the ice-breaking position.

[0055] In practice, the ratchet 9 and the pawl 10 can be selectively locked or unlocked, the ratchet 9 is rotatably connected to the mounting shell 1 via the ratchet pin 93, and the pawl 10 is rotatably connected to the mounting shell 1 via the pawl pin 104, thereby the ratchet 9 and the pawl 10 can be unlocked or locked by rotating the ratchet 9 or rotating the pawl 10, and a spring can be provided between the pawl 10 and the mounting shell 1 to facilitate the reset 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 9, and the ratchet 9 and the pawl 10 are locked and limited, so that the lock ring 200 cannot move along the ratchet 9, and the vehicle door is locked at this time.

[0056] Furthermore, initially, the ratchet 9 of the door lock assembly 100 is in an open state. When the vehicle door is locked, the matching positions of the ratchet 9 and the pawl 10 include the full locking position and the semi-locking position of the ratchet 9 and the pawl 10. If the vehicle door is gently pushed, the lock ring 200 fixed on the vehicle body hits the ratchet 9 installed on the door lock assembly 100, pushing the ratchet 9 to the semi-locking position. At this time, the vehicle door is not fully locked and there is a risk, so the vehicle door needs to be fully locked to improve the reliability of the door locking.

[0057] Specifically, the mounting shell 1 is used as a part of the door lock assembly 100 to support and install the internal structural parts of the door lock assembly 100, as well as to protect the structural parts of the door lock assembly 100. The drive motor 14 is installed in the mounting shell 1, and the drive motor 14 transmits power to the suction component 4; the suction component 4 includes a suction actuator arm 42, and the suction actuator arm 42 is rotatably connected to the mounting shell 1 through the suction arm pin 411, wherein the drive motor 14 can directly transmit power to the suction actuator arm 42 or indirectly transmit power, and the drive motor 14 drives the suction actuator when rotating. The arm 42 rotates so that the suction actuator arm 42 can move to the suction position. The suction position refers to the suction actuator arm 42 cooperating with the ratchet 9 and being able to transmit the power of the suction actuator arm 42 to the ratchet 9 so that the ratchet 9 moves from the semi-locked position to the fully locked position. That is, after the suction actuator arm 42 cooperates with the ratchet 9, the suction actuator arm 42 drives the ratchet 9 to rotate, and while rotating the ratchet 9 to cooperate with the pawl 10, it can also convert the initial locking cooperation between the ratchet 9 and the locking ring 200 into a more reliable locking cooperation, that is, the ratchet 9 is changed from the semi-locked position to the fully locked position.

[0058] Among them, in the semi-locked position, the reliability of the cooperation between the ratchet 9 and the lock ring 200 is poor, and there may be a risk of the door opening during the driving of the vehicle; and by making the suction actuator arm 42 drive the ratchet 9 to rotate so that the ratchet 9 and the pawl 10 cooperate at the same time and the ratchet 9 and the lock ring 200 form a more reliable cooperation. The more reliable cooperation can be understood as the state where the ratchet 9 and the lock ring 200 cooperate, and the ratchet 9 and the pawl 10 cooperate, the lock ring 200 is located in the ratchet 9 and is not easy to fall out of the ratchet 9. At this time, the risk of the lock ring 200 and the ratchet 9 separating during the driving of the vehicle can be reduced, thereby reducing the risk of the door opening. That is, at this time, the cooperation position of the ratchet 9 and the pawl 10 is the full locking position.

[0059] In addition, the position rod 3 of the embodiment of the present invention is poweredly connected to the drive motor 14, and the drive 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; and the drive motor 14 changes the position of the position rod 3 when driving the position rod 3 to move, and the position rod 3 can selectively press against the suction execution arm 42, thereby continuing to drive the position of the suction execution arm 42 to change through the movement of the position rod 3, that is, driving the suction execution arm 42 to switch from the suction position to the ice-breaking position, when the suction execution arm 42 reaches the ice-breaking position from the suction position, the suction execution arm 42 separates from the ratchet 9, and the suction execution arm 42 contacts the ice-breaking assembly, so that the ice-breaking assembly is poweredly connected to the ratchet 9, and at the same time, the position rod 3 drives the pawl 10 to disengage from the ratchet 9 to realize the function of electric unlocking, and the ice-breaking assembly can drive the ratchet 9 to move from the fully locked position to the unlocked 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 the temperature drop. When the suction actuator arm 42 is in the ice-breaking position, that is, the suction actuator arm 42 can transfer power to the ratchet 9 through the ice-breaking assembly to drive the ratchet 9 to move from the fully locked position to the unlocked position. The unlocking at this time refers to the position where the ratchet 9 is disengaged from the pawl 10 and the lock ring 200 is easy to disengage from the ratchet 9.

[0061] Then, the ice-breaking operation can be realized through the suction actuator arm 42, and the door lock assembly 100 can be changed from a semi-locked position to a fully locked position, and the change from the fully locked position to the unlocked position during ice breaking can be realized by the same drive motor 14. For example, the drive motor 14 drives the suction actuator arm 42 to drive the suction actuator arm 42 to move to the suction position, or the drive motor 14 drives the position rod 3 to drive the suction actuator arm 42 to move to the ice-breaking position through the position rod 3. That is, the drive motor 14 selectively transmits power to the position rod 3, or directly transmits power to the suction actuator arm 42, to realize different functions of the same drive motor 14, and integrates the automatic suction, ice-breaking and electric unlocking functions, thereby reducing the overall volume and thus reducing the weight of the vehicle door.

[0062] It should be further explained that the pawl 10 is provided with a first locking portion 101, the ratchet 9 is provided with a locking groove 92 for cooperating with the locking 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 9 rotates to the point where the second locking portion 922 cooperates with the first locking portion 101, the locking ring 200 is located in the locking groove 92 and the ratchet 9 and the pawl 10 are in a fully locked position, and when the ratchet 9 rotates to the point where the third locking portion 921 cooperates with the first locking portion 101, the locking ring 200 is located in the locking groove 92 and the ratchet 9 and the pawl 10 are in a semi-locked position.

[0063] In practice, refer to Figure 8 As shown, the ratchet 9 is provided with a locking groove 92, and the locking groove 92 is provided with an opening. The caliber of the locking groove 92 on the side close to the opening is larger than the caliber away from the opening, and when the ratchet 9 and the pawl 10 are in the fully locked position, the locking ring 200 is located at the bottom of the locking groove 92 of the ratchet 9 and is pressed against the bottom of the locking groove 92. At this time, the ratchet 9 and the pawl 10 are limited, and the caliber of the bottom of the locking groove 92 is small, so the locking ring 200 can be reliably locked and limited.

[0064] Furthermore, a second locking portion 922 is provided on one side of the lock slot 92 and a third locking portion 921 is provided on the other side, wherein the second locking portion 922 is located at the edge of the ratchet 9 and is configured as a mating tooth bent away from one side of the lock slot 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 mating surface located at the end of the lock slot 92. When the ratchet 9 is driven by the suction actuator arm 42 from the semi-locked position and moves to the fully locked position, as shown in FIG. Fig.17 and 18 As shown, Fig.17 The ratchet wheel 9 is in a semi-locked position relative to the pawl 10. Fig.18 The ratchet wheel 9 is in the fully locked position relative to the pawl 10, that is, Figure 17 to Figure 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, Figure 17 to Figure 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 Fig.17 and Fig.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. 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 through 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, so that it can be switched from the semi-locked position to the 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 providing 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 , Fig.17 and Fig.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 Fig.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 actuator arm 42 to drive the ratchet 9. That is, the half-locked position to the full-locked position is the ratchet 9 through Figure 17 to Figure 18 status, Fig.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; and Fig.18 In the embodiment of the present invention, the lock ring 200 is completely inserted into the lock groove 92 and contacts the bottom of the lock groove 92 and is not easily separated from the lock groove 92 .

[0068] Furthermore, the suction actuator arm 42 includes an engaging portion 422. When the suction actuator arm 42 cooperates with the driving arm 91, the engaging portion 422 of the suction actuator arm 42 cooperates with the driving arm 91 of the ratchet 9, thereby improving the reliability of the cooperation between the ratchet 9 and the suction actuator arm 42, and making it easier for the suction actuator arm 42 to drive the driving arm 91 to rotate when it rotates, thereby driving the ratchet 9 to rotate, and facilitating the switching of the ratchet 9 from a semi-locked position to a fully locked position.

[0069] In some embodiments, the door lock assembly 100 further includes: an unlocking component, the position rod 3 is connected to the unlocking component, and the driving motor 14 is suitable for pushing the unlocking component through the position rod 3 to drive the pawl 10 to unlock the ratchet 9.

[0070] Specifically, the drive motor 14 can independently drive the suction actuator arm 42 to rotate, thereby driving the suction actuator arm 42 to drive the position of the ratchet 9 to change. At this time, there is no power transmission between the suction actuator arm 42 and the position rod 3, and the unlocking assembly connected to the position rod 3 does not move. During electric unlocking, the drive motor 14 can drive the position rod 3 to move, and the movement of the position rod 3 drives the unlocking assembly to change. The position change of the unlocking assembly will drive the pawl 10 to move and disengage from the ratchet 9. At this time, the ratchet 9 and the pawl 10 are unlocked.

[0071] Therefore, through the setting of the position rod 3, the suction actuator arm 42 can be selectively moved to the suction position and the ice-breaking position. When the suction actuator arm 42 moves to the ice-breaking position, the position rod 3 drives the unlocking assembly to unlock. At this time, the pawl 10 will not limit the ratchet 9. Then, when the ratchet 9 cannot be rotated out, the suction actuator arm 42 can be moved to the ice-breaking position to drive the ratchet 9 to rotate out and unlock. That is to say, when the suction actuator arm 42 moves to the ice-breaking position, the position rod 3 can drive the pawl 10 to disengage from the ratchet 9 through the unlocking assembly. When the door lock assembly 100 is operated to break ice, the premise is that after the pawl 10 is disengaged from the ratchet 9, ice breaking is required only when the ratchet 9 cannot be rotated out due to environmental influences. Then, driving the position rod 3 by the drive motor 14 can not only realize the disengagement of the pawl 10 and the ratchet 9, but also realize that the position rod 3 drives the suction actuator arm 42 to the ice-breaking position, which is convenient to operate and saves time.

[0072] In some embodiments, the unlocking assembly includes an electric unlocking rocker arm 7 and an unlocking rocker arm 2; one end of the position rod 3 is connected to the unlocking rocker arm 2 and the other end is connected to the electric unlocking rocker arm 7, the unlocking rocker arm 2 is rotatably connected to the mounting shell 1, and the unlocking rocker arm 2 is power-connected to the pawl 10, the electric unlocking rocker arm 7 is power-connected to the drive motor 14, and the drive motor 14 is suitable for driving the electric unlocking rocker arm 7 to move along the first side when rotating, so that the electric unlocking rocker arm 7 drives the position rod 3 to move along the first side, and the position rod 3 drives the unlocking rocker arm 2 to rotate, thereby driving the pawl 10 and the ratchet 9 to unlock.

[0073] like Figure 1 In the embodiment, the driving motor 14 and the position rod 3 are configured to transmit power. The specific power transmission mode can be configured in combination with the direction in which the position rod 3 needs to move. For example, when the driving motor 14 rotates, the power can be transmitted to the electric unlocking rocker arm 7, and the electric unlocking rocker arm 7 moves toward Figure 1 When the right side moves, the first side is the right side, the electric unlocking rocker arm 7 and the position rod 3 are connected by power, and the electric unlocking rocker arm 7 drives the position rod 3 toward Figure 1 The position rod 3 is provided with a position rod hole 33, and the position rod 3 is hinged to the unlocking rocker arm 2 by the position rod pin 31 at the position rod hole 33. The unlocking rocker arm 2 is rotatably connected to the mounting shell 1 by the rocker arm connecting pin 21. When the position rod 3 moves toward the right side, the unlocking rocker arm 2 is driven to rotate. When the unlocking rocker arm 2 rotates, the position changes, which can drive the pawl 10 to rotate. At this time, the pawl 10 can be rotated to disengage from the ratchet 9.

[0074] Specifically, refer to Fig.10 As shown, the pawl 10 is provided with a connection port 102, and the pawl 10 is sleeved on the pawl pin 104 at the connection port 102, and the pawl 10 is rotatable relative to the pawl pin 104, and the pawl pin 104 is fixedly connected to the mounting shell 1, and the pawl 10 is also provided with a pressing portion 103. When the unlocking rocker arm 2 rotates, the pressing portion 103 of the pawl 10 can be pressed to allow the pawl 10 to rotate relative to the pawl pin 104, that is, Fig. 22 The pawl 10 rotates clockwise until it is disengaged from the ratchet wheel 9 and unlocked. Fig. 20 As shown, the horizontal arrow represents the movement direction of the position lever 3, and the clockwise arrow of the unlocking rocker arm 2 represents the rotation direction of the unlocking rocker arm 2. Fig. 20 is the position of the position rod 3 after movement, that is, Figure 1 From the perspective of the present invention, the pawl 10 needs to rotate counterclockwise, and the unlocking rocker arm 2 rotates clockwise. The unlocking rocker arm 2 includes a rocker arm driving part 22, and the rocker arm driving part 22 presses the pressing part 103 of the pawl 10 to make the pawl 10 rotate along Figure 1The pawl 10 is rotated counterclockwise to disengage the ratchet wheel 9, that is, it is in the state of electric unlocking. The electric unlocking, the suction unlocking and the ice breaking are all realized by the drive motor 14, which has a high degree of integration, reduces the volume of the door lock assembly 100, saves the number of drive motors 14, and also reduces the installation requirements for the vehicle door.

[0075] In some embodiments, a resisting portion 35 is provided on the outer side of the position rod 3, and the suction execution arm 42 is provided with a driving portion 421 cooperating with the resisting portion 35. When the position rod 3 is adapted to move along the first side, the resisting portion 35 presses the driving portion 421 to move the suction execution arm 42 to the ice-breaking position.

[0076] In practice, when the door lock assembly 100 is frozen due to low ambient temperature during electric unlocking, when the position rod 3 moves toward the right, the resisting portion 35 of the position rod 3 contacts the driving portion 421 of the suction actuator arm 42, so that the suction actuator arm 42 rotates counterclockwise along the viewing angle 1, changing the matching position of the suction actuator arm 42 and the ratchet 9, so that the suction actuator arm 42 is in the ice-breaking position and drives the ratchet 9 to unlock through the ice-breaking assembly. The resisting portion 35 of the position rod 3 is constructed as an arc surface, and the driving portion 421 of the suction actuator arm 42 is constructed as a cylindrical pin, or other structure that can contact the resisting portion 35 and drive the suction actuator arm 42 to rotate under the drive of the position rod 3.

[0077] Therefore, by setting the resisting part 35 and the driving part 421 of the suction execution arm 42, the position change of the position rod 3 not only drives the unlocking assembly to drive the pawl 10 to unlock, but also drives the suction execution arm 42 to be in the ice-breaking position, which is easy to operate.

[0078] In some embodiments, the ice-breaking component is an ice-breaking rocker arm 6, which is suitable for being power-connected to a driving arm 91. When the pawl 10 is unlocked from the ratchet 9, the suction actuator arm 42 drives the driving arm 91 to rotate in the second direction through the ice-breaking rocker arm 6, so that the ratchet 9 rotates in the second direction and is unlocked from the pawl 10.

[0079] Reference Fig. 9 As shown, the ice-breaking rocker arm 6 includes a first rod segment 61 and a second rod segment 62 that are bent and connected. The ice-breaking rocker arm 6 is rotatably 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, and a matching groove 621 is provided on the top of the first rod segment 61. When the suction execution arm 42 is in the ice-breaking position, the driving portion 421 of the suction execution arm 42 cooperates 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 selectively contacts the driving arm 91. When the suction execution arm 42 contacts the ice-breaking rocker arm 6 and drives the ice-breaking rocker arm 6 to move, refer to Fig. 22 As shown, the suction actuator arm 42 presses the ice-breaking rocker arm 6, so that the ice-breaking rocker arm 6 moves along Fig. 22 The counterclockwise rotation of Fig. 22 The arrow in the figure shows the rotation direction of the ice-breaking rocker arm 6. When the ice-breaking rocker arm 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 toward the unlocking direction.

[0080] When the above-mentioned suction actuator arm 42 switches the ratchet 9 from the semi-locked position to the fully locked position, the suction actuator arm 42 directly presses against the first driving surface 911 of the driving arm 91, that is, the rotation direction of the ratchet 9 directly driven by the suction actuator arm 42 is opposite to the rotation direction of the ratchet 9 driven by the suction actuator arm 42 through the icebreaking rocker arm 6.

[0081] Therefore, by setting the icebreaking rocker arm 6, the suction actuator arm 42 can selectively drive the ratchet 9 through the icebreaking rocker arm 6, or the suction actuator arm 42 can directly drive the ratchet 9. By driving the ratchet 9 to rotate in different ways, the ratchet 9 can be switched from a semi-locked position to a fully locked position, or the ratchet 9 can be switched from a fully locked position to an unlocked position. The same drive motor 14 is always used to transmit power to the suction actuator arm 42 to drive the ratchet 9 to rotate in different ways.

[0082] In some embodiments, the position rod 3 is rotatably connected to the snow-carrying rod 8, the mounting shell 1 is provided with an engaging structure 111, and the snow-carrying 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-carrying rod 8 to move and enables the first clamping portion 82 to engage with the engaging structure 111, so that the position of the position rod 3 remains fixed.

[0083] Reference Figure 4 As shown, the lower side of the position rod 3 is rotatably connected to the snow carrying rod 8 through the snow carrying pin 81. Figure 1 When the position rod 3 moves toward the right side, it can drive the snow-carrying rod 8 to move toward the right side at the same time. When the position rod 3 moves to the right side, it can drive the first clamping portion 82 of the snow-carrying rod 8 to be clamped in the position of the meshing structure 111 of the mounting shell 1. The meshing structure 111 of the mounting shell 1 is provided with locking teeth 1111. The first clamping portion 82 of the snow-carrying rod 8 can be constructed as an L-shaped clamping structure. The L-shaped clamping structure is clamped in the position of the locking teeth 1111, so that when the position rod 3 moves to the state of disengaging the pawl 10 from the ratchet 9, the position rod 3 can be temporarily maintained in the position after the movement, thereby keeping the pawl 10 and the ratchet 9 disengaged. When the ratchet 9 is rotated, the door can be smoothly unlocked and opened.

[0084] In some embodiments, the door lock assembly 100 also includes a signal rod 5, 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 power-connected to the ratchet 9, and 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 meshing 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 shell 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, and 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 when rotating. Fig.21 As shown in the figure, 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 meshing structure 111 of the mounting shell 1, and 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 meshing 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 aforementioned position rod 3 moves along the Figure 1 After moving toward the right side, the pawl 10 is driven to be disengaged from the ratchet wheel 9, and when the position lever 3 is reset, the pawl 10 is reset.

[0086] That is to say, by setting the signal rod 5, the signal rod 5 can be associated with the rotation of the ratchet 9, 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 is dynamically connected to a 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 actuator arm 42 are linked. For example, the suction rocker arm 41 and the suction actuator arm 42 are rotatably connected, but a pre-tightening 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 actuator arm 42 can be driven to rotate, or the suction rocker arm 41 and the suction actuator 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 Fig.15 As shown, if the suction rocker arm 41 is along Figure 1 Rotating clockwise can drive the suction actuator arm 42 along Figure 1 The viewing angle rotates clockwise, that is, the suction actuator arm 42 moves along Fig.15 If the drive motor 14 rotates counterclockwise, the suction actuator arm 42 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 suction actuator arm 42 moves along Fig.19 The initial state starts to rotate clockwise, and rotates clockwise to Fig. 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, firstly, the power transmission between the suction rocker arm 41 and the drive motor 14 is facilitated, and 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 worm wheel 152, a second worm 153, a second worm wheel 154 and an output gear 155. The drive motor 14 is connected to the first worm wheel 152 through the first worm 151, the first worm wheel 152 is selectively connected to the position rod 3, the first worm wheel 152 is connected to the second worm wheel 154 through the second worm 153, and a non-full circle gear 154 is provided on the side of the second worm wheel 154 close to the output gear 155. The non-full circle gear 1541 is selectively connected to the output gear 155, and the output gear 155 is connected to the engaging rocker arm 41.

[0092] In practice, the output shaft of the driving motor 14 is connected to the first worm 151, which meshes with the outer side of the primary worm wheel 152 to achieve power transmission, and the secondary worm wheel 154 is vertically connected to the second worm 153, which meshes with the outer side of the secondary worm wheel 154, and the secondary worm wheel 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 Fig.16 and Figure 1 As shown, the direction of the arrow indicates the direction of rotation. Fig.16The primary worm gear 152 rotates counterclockwise from the perspective, and the primary worm gear 152 is fixedly connected to the second worm 153, so that the second worm 153 rotates counterclockwise, and the shape structure of the meshing teeth 1542 between the second worm 153 and the secondary worm gear 154 is set to make the secondary worm gear 154 rotate counterclockwise, and the non-full circle gear 1541 at the rear side of the secondary 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, and the output gear 155 rotates clockwise, driving the suction rocker arm 41 to rotate along Figure 1 and Fig.16 The viewing angle rotates clockwise, that is, along Fig.15 The viewing angle is rotated counterclockwise, so that the suction rocker arm 41 contacts the driving arm 91, thereby driving the pawl 10 from the semi-locked position to the fully locked position.

[0093] When the actuator arm 42 needs to be attracted and moved to the ice-breaking position, as shown in FIG. Fig. 20 As shown, it is electric unlocking at this time, 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 also drives the electric unlocking rocker arm 7 to move toward the right while rotating clockwise. The shear head shown at the electric unlocking rocker arm 7 is in the direction of movement toward the right. When the electric unlocking rocker arm 7 moves toward the right, it drives the position rod 3 to move toward the right, that is, drives the pawl 10 and the ratchet 9 to unlock, and at the same time, 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, combined with Fig. 20 and Figure 4 As shown, Figure 4 The electric unlocking rocker arm 7 is provided with a limiting portion 73, and the bent end portion 34 of the position rod 3 is provided with a limiting surface 341, the limiting surface 341 is pressed against the limiting portion 73, so that the clockwise rotation of the first-stage worm gear 152 drives the electric unlocking rocker arm 7 to move toward the right side, and the electric unlocking rocker arm 7 is rotatably connected to the bent end portion 34 of the position rod 3 through the electric unlocking rocker arm pin 71, and a pre-tightening spring is arranged between the electric unlocking rocker arm 7 and the position rod 3, so that the electric unlocking rocker arm 7 can drive the position rod 3 to move, similar to the state in which the bent end portion 34 and the electric unlocking rocker arm 7 are hinged, that is, the clockwise rotation of the first-stage worm gear 152 can drive the electric unlocking rocker arm 7 to move, but because the limiting portion 73 of the electric unlocking rocker arm 7 cooperates with the limiting surface 341 of the bent end portion 34 of the position rod 3, the electric unlocking rocker arm 7 can only rotate toward one side relative to the bent end portion 34, that is, the electric unlocking rocker arm 7 can rotate relative to the bent end portion 34 along Fig. 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] Combination Fig.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 side, but the first-stage worm gear 152 transmits power to the suction actuator arm 42, so that the suction actuator arm 42 moves to the suction position.

[0096] Therefore, by providing a protruding structure 1521 on the primary worm gear 152, and keeping the electric unlocking rocker arm 7 and the position rod 3 in active connection or selectively limited, power can be transmitted, and the rotation direction of the electric unlocking rocker arm 7 is limited, that is, the primary worm gear 152 is controlled to rotate in different directions, so as to control the suction actuator arm 42 to be in the suction position or in the ice-breaking position. When in the suction 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 ice-breaking, that is, in the direction of unlocking. This can be achieved by a drive motor 14.

[0097] Reference Fig.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 a local meshing tooth 1542. When the non-full circle gear 1541 rotates to mesh with the output gear 155, it can drive the output gear 155 to rotate. When the meshing tooth 1542 of the non-full circle gear 1541 rotates 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 suction actuator arm 42 to move to the suction position, the meshing tooth 1542 of the non-full circle gear 1541 cooperates with the output gear 155. When the suction actuator arm 42 needs to be driven to move to the ice-breaking position through the position rod 3, the meshing tooth 1542 of the corresponding non-full circle gear 1541 is disengaged from the output gear 155. At this time, the position of the suction actuator arm 42 is controlled by the position rod 3.

[0098] Furthermore, during the design, a movable groove 32 is provided in the middle of the position rod 3, the output rotating shaft 1551 passes through the movable groove 32 and is connected to the mounting shell 1, the connecting portion 1552 of the output gear 155 is sleeved on the output rotating shaft 1551 and is dynamically connected to the suction rocker arm 41, that is, when the output gear 155 rotates, the connecting portion 1552 rotates to drive the suction rocker arm 41 to rotate, and transmits the power of the output gear 155 to the suction rocker arm 41. Since a movable groove 32 is provided in the middle of the position rod 3 and the movable groove 32 extends along the length direction of the position rod 3, the rotation of the output gear 155 and the movement of the position rod 3 can be performed independently.

[0099] In some embodiments, the door lock assembly 100 also includes a second elastic member, which is connected between the suction rocker arm 41 and the mounting shell 1, and is suitable for driving the suction rocker arm 41 to reset and thereby driving the suction actuator arm 42 to reset when the non-full circle 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 meshing portion 422 of the output gear 155 and the non-full circle gear 1541 is limited. When the output gear 155 is disengaged from the non-full circle gear 1541, the second elastic member can drive the suction rocker arm 41 to return to the initial position, thereby restoring the suction actuator arm 42 to the initial position. The second elastic member is a spring, that is, the suction actuator arm 42 is moved from Figure 18 to Figure 19 Switching, the suction execution arm 42 is reset to prepare for the next operation.

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