Abstract
Description
Technical Field
[0001] This invention relates to the field of vehicle manufacturing technology, and in particular to a door lock assembly and a vehicle having the door lock assembly. Background Technology
[0002] As the market share of electric vehicles increases year by year, more and more families are choosing to travel by car. During vehicle operation, if young passengers, such as children, accidentally open the car door, traffic accidents can easily occur. To protect the safety of young passengers, the current practice is to incorporate child lock devices into the door lock assembly to prevent accidental opening of the vehicle doors.
[0003] Existing child locks typically operate via manual levers or electronic methods. Manual levers can only be operated near the rear door, which is inconvenient and has poor sealing. They usually require multiple parts to operate, resulting in a complex structure, long transmission chain, low transmission efficiency, and a tendency to be forgotten. Furthermore, the child lock opening and closing slots need to be incorporated into the door structure, which detracts from the vehicle's aesthetics and negatively impacts the passenger experience. Electronic child locks, on the other hand, typically use an electrical signal to drive a motor, which in turn drives a worm gear, which in turn drives a rack and pinion rod to activate the locking mechanism inside the door lock. However, electronic child locks have longer and larger transmission rods, occupying considerable space in the door and hindering diverse layout options, lightweight design, and improved space utilization. They also significantly impact the overall spatial layout and design of the door, indicating room for improvement. Summary of the Invention

[0046] The following is for reference. Figures 1-10 The door lock assembly 100 according to an embodiment of the present invention has a short transmission distance and small size, which can improve the space utilization rate inside the door lock housing 1, reduce vehicle weight, reduce installation costs, and improve safety.
[0047] like Figures 1-10 As shown, the door lock assembly 100 according to an embodiment of the present invention includes: a drive rocker arm 2, a swing arm 3, and a child lock mechanism 4.
[0048] The drive rocker arm 2 and the swing arm 3 are coaxially arranged and rotatably mounted on the door lock housing 1. The swing arm 3 is provided with a first movable groove 31. The child lock mechanism 4 includes a drive structure 41 and a clutch linkage 42. The clutch linkage 42 is provided with a first pulling part 421. The first pulling part 421 is movably engaged with the first movable groove 31 so that the swing arm 3 selectively pushes the drive rocker arm 2 to unlock the car door when the first pulling part 421 is in different positions within the first movable groove 31.
[0049] Among them, vehicle door locks are an important part of ensuring vehicle safety. The structure and principle of vehicle door locks directly affect the ease of use and safety of the vehicle. The vehicle door lock controls the rotation of the rocker arm 2 by pulling the inner opening cable 9 to open the door. In order to prevent accidental activation of the door lock or accidental opening of the door by young passengers such as children, a child lock mechanism 4 can be set during use, thereby improving the safety of use.
[0050] Specifically, the door lock assembly 100 is provided with a door lock housing 1. The door lock housing 1 has multiple mounting posts 10 inside, which are spaced apart and can be used to install the components required for the operation of the door lock assembly 100. The door lock housing 1 can provide waterproof and dustproof protection for the internal components, and the door lock assembly 100 can be installed with the vehicle door through the door lock housing 1. The door lock assembly 100 is provided with a drive rocker arm 2 and a swing arm 3. The drive rocker arm 2 and the swing arm 3 are installed inside the door lock housing 1 through the same mounting post 10. The drive rocker arm 2 can rotate relative to the door lock housing 1, and the swing arm 3 can also rotate relative to the door lock housing 1. The swing arm 3 is provided with a first movable groove 31, which can be provided with an elongated hole and is arranged along the length direction of the swing arm 3.
[0051] Furthermore, the door lock assembly 100 is provided with a child lock mechanism 4, which can be used to lock or unlock the door to ensure the safety of the vehicle while it is in motion. The child lock mechanism 4 is provided with a drive structure 41 and a clutch linkage 42. The drive structure 41 is located inside the door lock housing 1 and is connected to the clutch linkage 42, providing the necessary power for the clutch linkage 42 to move. The clutch linkage 42 is a rod-shaped structure and is provided with a first pulling part 421. The first pulling part 421 can be a movable slider or a movable shaft, etc., and can be placed in a first movable groove 31, thereby movably cooperating with the first movable groove 31, so that the first pulling part 421 can be located in different positions within the first movable groove 31.
[0052] The drive structure 41 is connected to the clutch linkage 42 to provide driving force to the clutch linkage 42. Under the action of the drive structure 41, the first pulling part 421 of the clutch linkage 42 can move to different positions in the first movable groove 31, and the first pulling part 421 selectively pushes the drive rocker arm 2 to unlock the door. That is, the first pulling part 421 can move to a set position in the first movable groove 31, thereby enabling the first pulling part 421 to push the drive rocker arm 2 to unlock the door.
[0053] The first pulling part 421 can move within the first movable slot 31 to the child lock unlocking position, thereby allowing the first pulling part 421 to push the drive rocker arm 2 to unlock the door. The remaining positions of the first pulling part 421 within the first movable slot 31 can be configured as child lock deactivated positions. In other words, the first pulling part 421 has both child lock unlocking and child lock deactivated positions within the first movable slot 31. When the first pulling part 421 is in the child lock unlocking position, the rotation of the rocker arm 3 has no effect on the drive rocker arm 2, thus ensuring the door remains closed and preventing accidental opening of the door while the vehicle is in motion, improving safety. When the first pulling part 421 is in the child lock deactivated position, the rocker arm 3 rotates, and the rocker arm 3 can drive the first pulling part 421 to rotate. This, in turn, allows the clutch linkage 42 to push the drive rocker arm 2 to rotate, enabling the drive rocker arm 2 to unlock the door and open it, making operation convenient.
[0054] According to an embodiment of the present invention, the door lock assembly 100 drives the first pulling part 421 of the clutch linkage 42 through the drive structure 41, thereby causing the first pulling part 421 to selectively push the drive rocker arm 2 to unlock the door. It has a short transmission distance and small size, which can improve the space utilization rate inside the door lock housing 1 and the vehicle weight reduction, reduce the installation cost, and ensure the safety of the vehicle during driving. It has better performance and wider applicability.
[0055] In some embodiments, the drive structure 41 includes a drive member 411, a drive worm 412, and a transmission worm wheel 413. The transmission worm wheel 413 is rotatably mounted on the door lock housing 1. The drive worm 412 is connected to the output end of the drive member 411. The drive worm 412 meshes with the transmission worm wheel 413 for transmission. The transmission worm wheel 413 is adapted to push the clutch linkage 42 to drive the first pulling part 421 to move in the first movable groove 31 when rotating.
[0056] Specifically, such as Figures 1-2 As shown, the door lock assembly 100 is provided with a drive structure 41, which can drive the clutch linkage 42 to move relative to the door lock housing 1. The drive structure 41 is provided with a drive component 411, which can be a drive motor, etc. The drive component 411 is provided with an output shaft, which can output power. The output end of the drive component 411 is provided with a drive worm gear 412, which is connected to the output shaft of the drive component 411, so that the power output by the output shaft can be transmitted to the drive worm gear 412. The drive structure 41 is also provided with a transmission worm wheel 413, which is rotatably mounted in the door lock housing 1 through a mounting shaft. The drive worm gear 412 meshes with the transmission worm wheel 413, and the power transmitted to the drive worm gear 412 can then be transmitted to the transmission worm wheel 413. The transmission worm wheel 413 is connected to the clutch linkage 42.
[0057] When the drive unit 411 is running, it can drive the drive worm gear 412 to rotate, which in turn drives the transmission worm wheel 413 to rotate. The transmission worm wheel 413 is connected to the clutch linkage 42, which in turn drives the clutch linkage 42 to move. This allows the first pulling part 421 of the clutch linkage 42 to move within the first movable groove 31, thereby allowing the first pulling part 421 to switch between the child lock open position and the child lock closed position within the first movable groove 31, so that the car door can be locked and unlocked, improving safety.
[0058] In some embodiments, the transmission worm gear 413 is provided with a push port 414, and the clutch linkage 42 is provided with a push protrusion 422 spaced apart from the first pulling part 421. The push protrusion 422 extends into the push port 414. The push port 414 extends circumferentially along the transmission worm gear 413 and has a first push surface 4141 and a second push surface 4142 that are circumferentially opposite to each other along the transmission worm gear 413. The first push surface 4141 and the second push surface 4142 are used to push the push protrusion 422 to drive the clutch linkage 42 to move.
[0059] Specifically, such as Figures 4-9As shown, the drive structure 41 is provided with a transmission worm gear 413, which can drive the clutch linkage 42 to move, so that the first pulling part 421 of the clutch linkage 42 can switch between the child lock open position and the child lock closed position in the first movable groove 31. The clutch linkage 42 is also provided with a pushing protrusion 422, which can be configured as a pushing shaft, etc. The pushing protrusion 422 and the first pulling part 421 are spaced apart and placed on the clutch linkage 42, and the pushing protrusion 422 and the first pulling part 421 are respectively provided on both sides of the clutch linkage 42. The transmission worm gear 413 is provided with a pushing port 414, and the pushing protrusion 422 can extend into the pushing port 414. That is, when the transmission worm gear 413 rotates, the inner wall of the pushing port 414 can apply a force to the pushing protrusion 422, thereby causing the pushing protrusion 422 to drive the clutch linkage 42 to move.
[0060] Furthermore, the push port 414 is located at the edge of the transmission worm gear 413 and extends circumferentially along the transmission worm gear 413. The end of the push port 414 facing away from the rotation axis of the transmission worm gear 413 is open, and the push protrusion 422 can be placed inside the push port 414 through the open port, and as... Figure 8 As shown, the push port 414 has a first push surface 4141 and a second push surface 4142 that are circumferentially distributed opposite each other along the transmission worm gear 413. When the transmission worm gear 413 rotates, the first push surface 4141 and the second push surface 4142 can apply a pushing force and a pulling force to the push protrusion 422 respectively, so that the push protrusion 422 can drive the clutch linkage 42 to move, thereby allowing the first pulling part 421 of the clutch linkage 42 to switch between the child lock open position and the child lock closed position in the first movable groove 31. The structure is simple, the installation cost is low, and the safety of use is improved.
[0061] In some embodiments, the first pulling part 421 and the pushing protrusion 422 are respectively provided at both ends of the clutch linkage 42, and / or, the axis of the transmission worm gear 413 is perpendicular to the axis of the drive worm 412, and the axis of the transmission worm gear 413 is parallel and spaced apart from the axis of the rocker arm 3. That is, the first pulling part 421 and the pushing protrusion 422 are respectively provided at both ends of the clutch linkage 42, and the axis of the transmission worm gear 413 is perpendicular to the axis of the drive worm 412, and the axis of the transmission worm gear 413 is parallel and spaced apart from the axis of the rocker arm 3. Alternatively, only the first pulling part 421 and the pushing protrusion 422 may be provided at both ends of the clutch linkage 42, and only the axis of the transmission worm gear 413 may be perpendicular to the axis of the drive worm 412, and the axis of the transmission worm gear 413 may be parallel and spaced apart from the axis of the rocker arm 3.
[0062] Specifically, such as Figures 8-9As shown, the clutch linkage 42 is provided with a first pulling part 421 and a pushing protrusion 422, and the first pulling part 421 and the pushing protrusion 422 are respectively provided at both ends of the clutch linkage 42. The first pulling part 421 can be placed in the first movable groove 31 of the rocker arm 3, and the pushing protrusion 422 can be placed in the pushing port 414 of the transmission worm gear 413. By providing the first pulling part 421 and the pushing protrusion 422 at both ends of the clutch linkage 42, the rocker arm 3 and the transmission worm gear 413 can be separated, avoiding mutual interference when the rocker arm 3 and the transmission worm gear 413 rotate, and ensuring the reliability of the operation of each component.
[0063] Furthermore, the drive structure 41 is equipped with a transmission worm gear 413 and a drive worm 412. The drive worm 412 is connected to the drive component 411. The transmission worm gear 413 and the drive worm 412 mesh and transmit power. The axis of the transmission worm gear 413 is perpendicular to the axis of the drive worm 412, so that the power transmitted to the drive worm 412 can change its transmission direction when it is transmitted to the transmission worm gear 413. This improves the utilization rate of the internal space of the door lock housing 1, enhances vehicle lightweighting, and the transmission worm gear 413... The axis is parallel and spaced apart from the axis of the rocker arm 3, which can avoid mutual interference between the rocker arm 3 and the transmission worm gear 413 when they rotate, and ensure the reliability of the operation of each component. At the same time, the clutch linkage 42 is also provided with a first elastic element 425, which can be set as a spring. One end of the first elastic element 425 is connected to the clutch linkage 42, and the other end is connected to the door lock housing 1. It can apply force to the clutch linkage 42, thereby ensuring the movement path of the clutch linkage 42 and improving the reliability of the clutch linkage 42.
[0064] In some embodiments, the clutch linkage 42 has a push protrusion 423 at one end where the first pull portion 421 is provided, and the drive rocker arm 2 has a pressing protrusion 21 protruding toward the clutch linkage 42. The clutch linkage 42 is adapted to move to a position where the push protrusion 423 and the pressing protrusion 21 are facing each other or offset along the rotation direction of the drive rocker arm 2. When the push protrusion 423 and the pressing protrusion 21 are facing each other along the rotation direction of the drive rocker arm 2, the push protrusion 423 is adapted to push the pressing protrusion 21 to drive the drive rocker arm 2 to unlock the door.
[0065] Specifically, such as Figures 4-5 As shown, the clutch linkage 42 has a pushing protrusion 423 at one end where the first pulling part 421 is provided. The pushing protrusion 423 protrudes toward the end of the clutch linkage 42 away from the transmission worm gear 413, and the drive rocker arm 2 is provided with a pressing protrusion 21, which protrudes toward the clutch linkage 42.
[0066] Furthermore, the clutch linkage 42 is adapted to move to a position where the pushing convex surface 423 and the pressing convex part 21 are misaligned along the rotation direction of the drive rocker arm 2, such as... Figure 9As shown, when the first pulling part 421 of the clutch linkage 42 driven by the transmission worm gear 413 is located in the child lock position in the first movable groove 31, the rocker arm 3 can drive the clutch linkage 42 to rotate when it rotates. At this time, the movement trajectory of the pushing convex surface 423 of the clutch linkage 42 is misaligned with the pressing convex part 21, so that the rocker arm 2 remains stationary when the rocker arm 3 rotates, thereby locking the door.
[0067] Furthermore, the clutch linkage 42 is adapted to move to a position where the pushing convex surface 423 and the pressing convex part 21 are directly opposite each other along the rotation direction of the drive rocker arm 2, such as... Figures 4-5 As shown, the pushing convex surface 423 can push the pressing convex part 21 to drive the rocker arm 2 to unlock the car door. That is, when the transmission worm gear 413 drives the first pulling part 421 of the clutch linkage 42 to be in the child lock position in the first movable groove 31, the rocker arm 3 can rotate to drive the clutch linkage 42 to rotate. At this time, the movement trajectory of the pushing convex surface 423 of the clutch linkage 42 intersects with the pressing convex part 21, so that the pushing convex surface 423 can press against the pressing convex part 21 during the movement. In turn, when the rocker arm 3 rotates, the pushing convex surface 423 can drive the rocker arm 2 to rotate to open the car door. This can reduce the number of parts and save the internal space of the door lock housing 1.
[0068] The rocker arm 3 is also coaxially provided with a second elastic element 32, which can be a spring. The second elastic element 32 can provide elastic force to the rocker arm 3, so that the rocker arm 3 can be reset after it moves. The drive rocker arm 2 is also coaxially provided with a third elastic element 23, which can be a spring. The third elastic element 23 can provide elastic force to the drive rocker arm 2, so that the drive rocker arm 2 can be reset after it moves, thus ensuring the reliability of the operation of each component.
[0069] In some embodiments, the transmission worm gear 413 is configured to drive the first pulling part 421 from the child lock open position to the child lock closed position when rotating about a first direction, and is also configured to drive the first pulling part 421 from the child lock closed position to the child lock open position when rotating about a second direction.
[0070] Specifically, the driving component 411 can drive the driving worm 412 to rotate, which in turn drives the transmission worm wheel 413 to rotate. When the power output direction of the driving component 411 is different, the rotation direction of the transmission worm wheel 413 is also different, allowing the transmission worm wheel 413 to rotate around a first direction and a second direction respectively. The transmission worm wheel 413 is provided with a push port 414, and the push protrusion 422 of the clutch linkage 42 is placed in the push port 414. Figure 8As shown, the push port 414 is provided with a first push surface 4141 and a second push surface 4142. When the transmission worm gear 413 rotates around the first direction, the first push surface 4141 can push the first pulling part 421 from the child lock position of the first movable groove 31 to the child lock position. When the transmission worm gear 413 rotates around the second direction, the second push surface 4142 can pull the first pulling part 421 from the child lock position of the first movable groove 31 to the child lock position, ensuring safety during use.
[0071] In this embodiment, one of the first direction and the second direction can be set to a clockwise direction and the other can be set to a counterclockwise direction. That is, the first direction can be set to a clockwise direction and the second direction can be set to a counterclockwise direction, or the first direction can be set to a counterclockwise direction and the second direction can be set to a clockwise direction. In this embodiment, the first direction always refers to the clockwise direction and the second direction always refers to the counterclockwise direction.
[0072] In some embodiments, the door lock assembly 100 further includes a transmission structure 5, a pawl slider 6, and a pawl 7. The pawl 7 is rotatably mounted on the door lock housing 1, and the pawl slider 6 is slidably mounted on the pawl 7. The pawl 7 is adapted to drive the pawl slider 6 to push the drive rocker arm 2 to unlock the door. The transmission structure 5 is movably mounted on the door lock housing 1. The transmission worm gear 413 is configured to drive the transmission structure 5 to move when rotating about a second direction, so as to drive the pawl slider 6 to move relative to the pawl 7 and make the movement trajectory of the pawl slider 6 offset from that of the drive rocker arm 2.
[0073] Specifically, the door lock assembly 100 also includes a transmission structure 5, a pawl slider 6, and a pawl 7. The transmission structure 5 is installed inside the door lock housing 1 and is movable relative to the door lock housing 1. The pawl 7 is installed inside the door lock housing 1 via a mounting shaft and is rotatable relative to the door lock housing 1. The pawl slider 6 is installed on the pawl 7 and is slidable relative to the pawl 7. Figure 6 As shown, the pawl slider 6 is provided with a fourth pushing surface 61. When the child lock is in the open position, when the pawl 7 rotates in the first direction, it can drive the pawl slider 6 to rotate in the first direction as well. The fourth pushing surface 61 can press against the drive rocker arm 2, thereby driving the drive rocker arm 2 to rotate in the second direction, thereby opening the car door and realizing the outward opening of the car door.
[0074] Furthermore, when the transmission worm gear 413 rotates around the second direction, the clutch linkage 42 can be switched to the child lock position. During the rotation of the transmission worm gear 413, the transmission structure 5 can be driven to move. The transmission structure 5 can drive the pawl slider 6 to move relative to the pawl 7. When the pawl 7 rotates along the first direction, it drives the moved pawl slider 6 to rotate together. At this time, the movement trajectory of the pawl slider 6 is offset from that of the drive rocker arm 2, that is, the movement of the pawl slider 6 will not affect the drive rocker arm 2, that is, the door is locked, ensuring safety in use.
[0075] The ratchet 7 is provided with a limiting groove 72, and the ratchet slider 6 is provided with a limiting block on the side facing the ratchet 7. The limiting block can be placed in the limiting groove 72, so that when the ratchet slider 6 moves relative to the ratchet 7, it can move along a predetermined route to ensure operational reliability. At the same time, the ratchet 7 is also provided with a sixth elastic element 71, which can be set as a spring. The sixth elastic element 71 can provide elastic force to the ratchet 7, so that the ratchet 7 can be reset after action. The ratchet slider 6 is also provided with a fifth elastic element 62, which can be set as a spring. The ratchet slider 6 is provided with a limiting post 63. The fifth elastic element 62 is sleeved on the limiting post 63 and one end is connected to the limiting plate 64 provided on the ratchet slider 6, and the other end is connected to the mounting post 10. The fifth elastic element 62 can provide elastic force to the ratchet slider 6, so that the ratchet slider 6 can be reset after action, ensuring the operational reliability of each component.
[0076] In some embodiments, the transmission structure 5 includes a rotating rocker arm 51 and a locking link 52. The rotating rocker arm 51 is rotatably mounted on the door lock housing 1, and the locking link 52 is movable relative to the door lock housing 1 and rotatably connected to the rotating rocker arm 51. The transmission worm gear 413 is adapted to drive the rotating rocker arm 51 to rotate so as to push the locking link 52 to move and thereby drive the pawl slider 6 to move.
[0077] Specifically, the transmission structure 5 is provided with a rotating rocker arm 51 and a locking link 52. Both the rotating rocker arm 51 and the locking link 52 are located inside the door lock housing 1. The rotating rocker arm 51 is rotatably mounted on the door lock housing 1 via a mounting shaft, and the locking link 52 is movable relative to the door lock housing 1. The locking link 52 is provided with a rotating hole 521, and the rotating rocker arm 51 is provided with a rotating shaft 512. The rotating shaft 512 can be placed in the rotating hole 521, so that the locking link 52 and the rotating rocker arm 51 are rotatably connected. Figures 1-2 As shown, the locking link 52 is provided with a locking boss 522, and the rotating rocker arm 51 forms a third pushing surface 511. When the transmission worm gear 413 rotates in the second direction, it can press against the third pushing surface 511, thereby pushing the rotating rocker arm 51 to rotate in the second direction. This allows the rotating rocker arm 51 to drive the locking link 52 to move. During the movement, the locking boss 522 of the locking link 52 can press against the pawl slider 6, allowing the pawl slider 6 to move relative to the pawl 7, so that the movement trajectory of the pawl slider 6 is offset from that of the driving rocker arm 2, thereby locking the door.
[0078] The rotating rocker arm 51 is provided with a fourth elastic element 513, which can be a spring. One end of the fourth elastic element 513 is connected to the rotating rocker arm 51, and the other end is connected to the door lock housing 1. The fourth elastic element 513 can provide elastic force to the rotating rocker arm 51, so that after the rotating rocker arm 51 rotates a certain angle in the second direction under the action of the transmission worm gear 413, it can continue to rotate under the elastic force of the fourth elastic element 513. This allows the rotating rocker arm 51 to run to a predetermined position and remain fixed under the action of the elastic force of the fourth elastic element 513, ensuring the reliability of the operation of each component.
[0079] In some embodiments, the door lock assembly 100 further includes a centering elastic element 415, which is coaxially disposed with the transmission worm gear 413 and is used to apply an elastic force toward centering rotation to the transmission worm gear 413.
[0080] Specifically, such as Figure 1 As shown, the door lock assembly 100 is also provided with a center position elastic element 415. The center position elastic element 415 can be set as a spring, and the center position elastic element 415 is coaxially arranged with the transmission worm gear 413. The transmission worm gear 413 is set with a center position. When the transmission worm gear 413 is in the center position, the center position elastic element 415 is in the normal state. When the transmission worm gear 413 rotates in the first direction or the second direction, the center position elastic element 415 is compressed. At this time, the center position elastic element 415 can apply an elastic force to the transmission worm gear 413 towards the center position. The transmission worm gear 413 can return to the center position under the action of the elastic force, thereby ensuring the running stability of the transmission worm gear 413. Here, the center position refers to the initial position of the transmission worm gear 413 when it moves.
[0081] In some embodiments, the drive worm 412 and the clutch link 42 are located on both sides of the rotation axis of the transmission worm wheel 413, and the drive worm 412 and the clutch link 42 are distributed relative to each other along the radial direction of the transmission worm wheel 413.
[0082] Specifically, the drive worm 412 meshes with the transmission worm wheel 413, allowing the drive worm 412 to drive the transmission worm wheel 413 to rotate. The transmission worm wheel 413 is connected to the clutch linkage 42, allowing the clutch linkage 42 to move during the rotation of the transmission worm wheel 413. The drive worm 412 and the clutch linkage 42 are respectively located on both sides of the rotation axis of the transmission worm wheel 413. The drive worm 412 and the clutch linkage 42 are radially opposite to each other along the transmission worm wheel 413, that is, the clutch linkage 42 and the drive worm 412 are spaced apart. This avoids mutual interference between the clutch linkage 42 and the drive worm 412 during operation, ensuring the reliability of the operation of each component. It also makes full use of the space on both sides of the transmission worm wheel 413, improving the utilization rate of the internal space of the door lock housing 1.
[0083] In some embodiments, the door lock assembly 100 further includes a central control worm gear 8, which is connected to a central control drive component 83. The central control worm gear 8 is rotatably mounted on the door lock housing 1 and is used to push the drive rocker arm 2 to move so as to unlock the door.
[0084] Specifically, the door lock assembly 100 is equipped with a central control worm gear 8, which is rotatably mounted inside the door lock housing 1 via a mounting shaft. The central control worm gear 8 is coaxially arranged with the rocker arm 3 and the drive rocker arm 2. The central control worm gear 8 is equipped with a worm gear slider 81, and the drive rocker arm 2 is equipped with a second movable groove 22. The worm gear slider 81 can be placed in the second movable groove 22. When the central control worm gear 8 rotates, the worm gear slider 81 can press against the inner wall of the second movable groove 22, thereby pushing the drive rocker arm 2 to rotate. Figure 10 As shown, the central control worm gear 8 is connected to the central control drive component 83. The central control drive component 83 can drive the central control worm gear 8 to rotate. When the central control drive component 83 drives the central control worm gear 8 to rotate in the second direction, the worm gear slider 81 can push the drive rocker arm 2 to rotate in the second direction together, thereby unlocking the door. That is, when the clutch linkage 42 is in the child lock position and the locking boss 522 presses against the pawl slider 6, the door can be unlocked through the central control worm gear 8. The central control worm gear 8 is provided with a seventh elastic element 82, which can be set as a spring. The seventh elastic element 82 can provide elastic force to the central control worm gear 8, so that the central control worm gear 8 can be reset after action, ensuring operational reliability.
[0085] In some embodiments, the rocker arm 3 is connected to an inner opening pull cable 9, and / or the clutch linkage 42 is provided with a first weight reduction hole 424, that is, the rocker arm 3 is connected to an inner opening pull cable 9 and the clutch linkage 42 is provided with a first weight reduction hole 424, or only the rocker arm 3 is connected to an inner opening pull cable 9, or only the clutch linkage 42 is provided with a first weight reduction hole 424.
[0086] Specifically, in this embodiment, the rocker arm 3 is connected to an inwardly opening pull cable 9, and the clutch linkage 42 is provided with a first weight-reducing hole 424, such as... Figure 10 As shown, the rocker arm 3 is connected to an inward-opening cable 9. The rocker arm 3 is provided with a pull groove 33, and the inward-opening cable 9 is provided with a second pull part. The second pull part can be placed in the pull groove 33. When the car door is opened from the inside, the inward-opening cable 9 can drive the rocker arm 3 to rotate in the second direction. At this time, if the first pull part 421 of the clutch linkage 42 is located in the child lock position of the first movable groove 31, pushing the convex surface 423 can drive the rocker arm 2 to rotate, thereby opening the car door. Figures 2-3 As shown, the clutch link 42 is provided with a first weight reduction hole 424. Multiple first weight reduction holes 424 are provided and spaced apart on one side of the clutch link 42. This reduces the material required for manufacturing the clutch link 42 and improves vehicle lightweighting. Additionally, as... Figure 2As shown, the locking link 52 is provided with a second weight reduction hole 523. Multiple second weight reduction holes 523 are provided and distributed at intervals on one side of the locking link 52. This can reduce the material required for manufacturing the clutch link 42 and improve the vehicle's lightweight design.
[0087] The present invention also proposes a vehicle.

[0089] According to an embodiment of the present invention, the vehicle is provided with a door lock assembly 100, and the door lock assembly 100 drives the first pulling part 421 of the clutch linkage 42 through the drive structure 41, thereby causing the first pulling part 421 to selectively push the drive rocker arm 2 to unlock the door. Its transmission distance is short and its size is small, thereby improving the space utilization rate inside the door lock housing 1 and the vehicle's lightweight design, reducing the installation cost, and ensuring the safety of the vehicle during driving. It has better performance and a wider range of applications.
