Description

Technical Field

[0001] This invention relates to the field of vehicle manufacturing technology, and more particularly to a door lock assembly and a vehicle having the door lock assembly. Background Technology

[0002] Currently, the drive components of the central control unit of car door locks in automotive manufacturers often adopt the form of actuating components or transmission rods. Their internal working principle is as follows: a drive motor drives a mating worm gear to rotate, which in turn rotates the driven worm wheel. The worm wheel further transmits power to a mating worm wheel assembly, which then transmits power sequentially to the first actuating component and the second actuating component. The actuating component contacts a pawl, which controls the opening and closing of the door lock. This type of drive device transmits power in multiple stages, resulting in a large number of transmission components, occupying a large volume within the door lock cavity, increasing the failure rate of the door lock transmission chain, and taking up a large area of ​​the door lock cavity. This is not conducive to the arrangement of other transmission components and improving space utilization. Furthermore, the components have a single function, only able to transmit a single action purpose sequentially downwards through cooperation with the worm wheel drive component, unable to achieve the cooperative action of a single component with multiple components, and the complex design of the cooperation makes it more difficult, hindering the automated production of the components. Therefore, there is room for improvement. Summary of the Invention

Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0044] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0045] Unless otherwise specified, the front-back direction in this application refers to the longitudinal direction of the vehicle, i.e., the X direction; the left-right direction refers to the lateral direction of the vehicle, i.e., the Y direction; and the up-down direction refers to the vertical direction of the vehicle, i.e., the Z direction.

[0046] The following is for reference. Figures 1-9 The door lock assembly 100 according to an embodiment of the present invention is configured such that, when the central locking system is in the unlocked state, the door can be unlocked by pulling the drive rocker arm 2 outward through the pawl assembly. When the central locking system is in the locked state, the door cannot be unlocked by pulling outward, thus ensuring the safety of unlocking the door. In addition, the door lock assembly 100 has a small number of structural components, a short transmission chain, and high unlocking efficiency.

[0047] like Figures 1-9 As shown, a door lock assembly 100 according to an embodiment of the present invention includes: a drive rocker arm 2 and a central control mechanism 5.

[0048] The drive rocker arm 2 is rotatably mounted on the door lock housing 1. That is, the drive rocker arm 2 is mounted on the door lock housing 1 and can rotate relative to the door lock housing 1. For example, if there is a mounting post 11 on the door lock housing 1, the drive rocker arm 2 is correspondingly provided with a mounting hole. The drive rocker arm 2 is mounted on the mounting post 11 through the mounting hole, and the drive rocker arm 2 can rotate around the mounting post 11. It should be noted that the drive rocker arm 2 is the actuator for unlocking the car door. By driving the drive rocker arm 2 to rotate relative to the door lock housing 1, the car door can be unlocked. The drive rocker arm 2 includes a first pushing part 21. The first pushing part 21 is used to cooperate with other structures to push the drive rocker arm 2 to rotate.

[0049] The central control mechanism 5 includes a pawl assembly, which has an engaged state and an unengaged state. When the pawl assembly is in the unengaged state, it is adapted to push the first push part 21 to drive the rocker arm 2 to move and unlock the door. In other words, when the pawl assembly is in the unengaged state, the first push part 21 can be pushed by the pawl assembly to make the rocker arm 2 rotate relative to the door lock housing 1, thereby unlocking the door.

[0050] Specifically, the pawl assembly is movably mounted on the door lock housing 1, and the pawl assembly has two extreme positions. In the two extreme positions, the pawl assembly is in the locked state and the unlocked state, respectively. When the pawl assembly is in the unlocked state, the pawl assembly pushes the first push part 21 to drive the rocker arm 2 to rotate, thereby unlocking the door. The unlocking method of the pawl assembly is door opening unlocking from the outside.

[0051] Furthermore, when the pawl assembly is in the locked state, it cannot drive the rocker arm 2 to rotate, meaning the door cannot be unlocked via the pawl assembly. This renders the locked unlocking ineffective and prevents the door from being pulled outwards for unlocking. Therefore, depending on whether the central control mechanism 5 is locked or unlocked, the door unlocking status can be flexibly controlled, making door unlocking safer and more reliable. Moreover, the entire door unlocking transmission chain is short, the unlocking efficiency is high, the applicability is stronger, and the structure is simple, compact, and has low development costs.

[0052] According to the embodiments of the present invention, the door lock assembly 100 is configured with the cooperation between the central control mechanism 5 and the drive rocker arm 2, which enables the drive rocker arm 2 to be effectively unlocked when the central control is in the unlocked state. The door lock assembly 100 has fewer structural components, a shorter transmission chain, and higher efficiency, thereby improving the reliability and durability of the door lock assembly 100. It also occupies less space, is lightweight, and has stronger applicability.

[0053] In some embodiments, the door lock assembly 100 further includes a central rocker arm 3 and a child lock mechanism 4. The drive rocker arm 2 further includes a second pusher 22. The child lock mechanism 4 has a child lock closed state and a child lock open state. The central rocker arm 3 is adapted to push the second pusher 22 to drive the drive rocker arm 2 to move in order to unlock the door when the child lock mechanism 4 is in the child lock closed state. That is, when the child lock mechanism 4 is in the child lock closed state, the central rocker arm 3 can push the second pusher 22 to make the drive rocker arm 2 rotate relative to the door lock housing 1, thereby unlocking the door.

[0054] Specifically, the first pushing part 21 and the second pushing part 22 are spaced apart. The second pushing part 22 is used to cooperate with other structures to drive the drive rocker arm 2 to rotate. The central rocker arm 3 and the child lock mechanism 4 are both movably mounted on the door lock housing 1. The child lock mechanism 4 has two extreme positions. In the two extreme positions, the child lock mechanism 4 is in the child lock closed state and the child lock open state, respectively. When the child lock mechanism 4 is in the child lock closed state, the central rocker arm 3 pushes the second pushing part 22 to drive the drive rocker arm 2 to rotate, thereby unlocking the car door. The unlocking method of the central rocker arm 3 is the inward door unlocking.

[0055] Furthermore, when the child lock mechanism 4 is in the unlocked state, the central rocker arm 3 cannot drive the drive rocker arm 2 to rotate, meaning the door cannot be unlocked via the central rocker arm 3, rendering the safety unlocking ineffective and preventing the door from being unlocked by pulling inward. Therefore, depending on whether the child lock mechanism 4 is in the unlocked or locked state, the unlocking status of the door can be flexibly controlled, making door unlocking safer and more reliable. Moreover, the entire door unlocking transmission chain is short, the unlocking efficiency is high, the applicability is stronger, and the structure is simple, compact, and has low development costs.

[0056] Furthermore, the central rocker arm 3 and the child lock mechanism 4 are located on the right side of the central control mechanism 5. Thus, in the overall structure of the door lock assembly 100, the left side of the door lock assembly 100 is used to realize the door opening and unlocking from the outside, and the right side of the door lock assembly 100 is used to realize the door opening and unlocking from the inside. Its structural arrangement is clear and reasonable.

[0057] Therefore, in this embodiment, the door is unlocked by driving the rocker arm 2 through the central rocker arm 3 and the pawl assembly. The door can be unlocked selectively during unlocking. Multiple functions are achieved with one part, reducing the number of parts, reducing the size of the door lock, simplifying the cooperation between transmission components, reducing costs, and enhancing the competitiveness of the product itself.

[0058] In some embodiments, the first pushing part 21 and the second pushing part 22 are located on both sides of the drive rocker arm 2; and / or, the first pushing part 21 and the second pushing part 22 are circumferentially spaced apart along the rotation axis of the drive rocker arm 2.

[0059] Specifically, such as Figure 4As shown, the first pushing part 21 and the second pushing part 22 are spaced apart and distributed on both sides of the drive rocker arm 2. That is, the first pushing part 21 is located on the left side of the drive rocker arm 2 and is close to the pawl assembly, while the second pushing part 22 is located on the right side of the drive rocker arm 2 and is close to the child lock mechanism 4 and the central rocker arm 3. This arrangement facilitates the pawl assembly to push the first pushing part 21 and the central rocker arm 3 to push the second pushing part 22.

[0060] Meanwhile, depending on the positional relationship between different structures, the first pushing part 21 and the second pushing part 22 can be circumferentially distributed along the rotation axis of the drive rocker arm 2 to cooperate well with the pawl assembly and the central rocker arm 3. Thus, through the above two methods, the first pushing part 21 and the second pushing part 22 can be flexibly set to correspond to two different door opening methods.

[0061] In some embodiments, the first pushing part 21 and the second pushing part 22 are both configured as pressing protrusions and extend protruding from both sides of the drive rocker arm 2 in a direction away from each other.

[0062] Specifically, such as Figure 4 As shown, both the first pushing part 21 and the second pushing part 22 are constructed as pressing protrusions. The two pressing protrusions extend outward in a direction away from each other. The first pushing part 21 extends outward to the left, and the second pushing part 22 extends outward to the right. The structures of the two pressing protrusions can be set differently. In actual design, the structure of the second pushing part 22 is sharper than that of the first pushing part 21, which is used to match different thrusts to drive the first pushing part 21 and the second pushing part 22. The protruding parts of the two pressing protrusions and the connection with the drive rocker arm 2 are all formed with arc transitions, which ensures the structural strength of the pressing protrusions, improves the reusability of the drive rocker arm 2, and the structure of the pressing protrusions is smoother, so that it will not scratch people during installation.

[0063] In some embodiments, the door lock assembly 100 further includes a central control worm gear 55, which is connected to the electric drive structure 6. The central control worm gear 55 is rotatably mounted on the door lock housing 1. The drive rocker arm 2 is also provided with a third push part 24. The central control worm gear 55 is used to push the drive rocker arm 2 to move at the third push part 24 to unlock the door. That is, the electric drive structure 6 drives the central control worm gear 55 to push the third push part 24 to push the drive rocker arm 2 to rotate, thereby realizing the electric unlocking of the door.

[0064] Specifically, the door lock housing 1 is provided with a mounting post 11. The central control worm gear 55, the central rocker arm 3, and the drive rocker arm 2 can be jointly mounted on the same mounting post 11 of the door lock housing 1. The central control worm gear 55, the central rocker arm 3, and the drive rocker arm 2 are all rotatable relative to the door lock housing 1. The central control worm gear 55 is located below the drive rocker arm 2, and the central control worm gear 55 is poweredly connected to the electric drive structure 6. For example... Figure 1 As shown, the electric drive structure 6 includes a drive motor 61 and a worm gear 62. The drive motor 61 and the worm gear 62 are connected by a power source, and the worm gear 62 meshes with the central control worm wheel 55 for transmission. In this way, the drive motor 61 transmits the driving force to the central control worm wheel 55 through the worm gear 62 to drive the central control worm wheel 55 to rotate.

[0065] Furthermore, the drive rocker arm 2 is provided with a third pusher 24, which is used to cooperate with the central control worm gear 55 to realize the rotation of the drive rocker arm 2. Thus, after receiving the electric unlocking signal, the drive motor 61 drives the worm 62 to rotate, which in turn drives the central control worm gear 55 to rotate. The central control worm gear 55 pushes the third pusher 24 to move, which can drive the drive rocker arm 2 to rotate, so as to realize the electric unlocking of the car door.

[0066] In some embodiments, the third pusher 24 is located between the first pusher 21 and the second pusher 22, and is spaced apart from the rotation axis of the drive rocker arm 2.

[0067] Specifically, the third pushing part 24, the first pushing part 21, and the second pushing part 22 are all spaced apart, and the third pushing part 24 is located between the first pushing part 21 and the second pushing part 22. The third pushing part 24 cooperates with the central control worm gear 55, and the third pushing part 24 can be positioned close to the first pushing part 21. The third pushing part 24 is spaced apart from the rotation axis of the drive rocker arm 2, and the third pushing part 24 is located on the rotation trajectory of the drive rocker arm 2. This facilitates the third pushing part 24 to push the central control worm gear 55 to rotate around its own rotation axis, so as to realize the electric unlocking of the car door.

[0068] Therefore, a first pushing part 21, a second pushing part 22, and a third pushing part 24 are provided on the drive rocker arm 2, integrating the three pushing structures into the drive rocker arm 2. That is, the three pushing parts 21, 22, and 24 are pushed by the pawl assembly, the central rocker arm 3, and the central control worm gear 55 respectively to drive the drive rocker arm 2 to rotate, which can realize the door unlocking from the outside, unlocking from the inside, and unlocking by electricity respectively, and the three do not interfere with each other. This improves the integrated setting of the door lock assembly 100, thereby reducing the number of parts for door unlocking and reducing manufacturing costs.

[0069] In some embodiments, the third pushing part 24 is configured as a pushing groove, which is an arc-shaped groove and extends circumferentially along the rotation axis of the driving rocker arm 2.

[0070] Specifically, the third pushing part 24 is constructed as a pushing groove, which is distributed along the movement trajectory of the drive rocker arm 2 and penetrates through the thickness of the drive rocker arm 2, such as... Figure 4As shown, the shape of the push slide can be set as an arc-shaped groove, and the push slide extends circumferentially along the rotation axis of the drive rocker arm 2 to form an arc-shaped push slide. The four corners of the push slide are provided with rounded transitions, which makes the push slide structure smoother. The rounded corner size is small and does not affect the cooperation between the push slide and other structures. Thus, the arc-shaped push slide is conducive to the cooperation between the push slide and the central control worm gear 55.

[0071] It should be noted that the push slide can also be constructed in other shapes such as elongated strips, which can facilitate the cooperation between the central control worm gear 55 and the push slide after rotation.

[0072] The central control worm gear 55 is provided with a drive protrusion 551. The drive protrusion 551 extends into the push slide groove and is adapted to press against the inner end face of the push slide groove to drive the drive rocker arm 2 to rotate. In other words, by the drive protrusion 551 pressing against the push slide groove to drive the drive rocker arm 2 to rotate, the central control worm gear 55 drives the drive rocker arm 2 to rotate.

[0073] Specifically, the drive protrusion 551 protrudes from the surface of the central control worm gear 55. The drive protrusion 551 is spaced apart from the rotation axis of the central control worm gear 55 and is correspondingly set with the push groove. The width of the push groove is greater than the size of the drive protrusion 551, and the shape of the drive protrusion 551 is matched with the size of the push groove. Figure 2 and Figure 9 As shown, the driving protrusion 551 can be constructed as a block, and the four corners of the driving protrusion 551 are all rounded to make the structure of the driving protrusion 551 smoother.

[0074] When the door is electrically unlocked, the central control worm gear 55 rotates, the drive protrusion 551 rotates with the central control worm gear 55, and the drive protrusion 551 extends into the push slide groove. The drive protrusion 551 presses against the inner end face of the push slide groove and pushes the push slide groove to rotate, so that the drive protrusion 551 pushes the drive rocker arm 2 to rotate, thereby realizing the door is electrically unlocked.

[0075] In some embodiments, the door lock assembly 100 further includes a worm gear reset member 56. The central control worm gear 55 is adapted to drive the protrusion 551 to press against and push one inner end face of the push groove when rotating in a first direction. The worm gear reset member 56 is used to apply an elastic force rotating in a second direction to the central control worm gear 55 so that the drive protrusion 551 presses against the other inner end face of the push groove. That is, the central control worm gear 55 can be reset by the elastic force of the worm gear reset member 56 on the central control worm gear 55.

[0076] Specifically, the worm gear reset component 56 can be coaxially mounted with the central control worm gear 55. The worm gear reset component 56 can be a central control spring, and the first direction can be counterclockwise, and the second direction can be clockwise. When the drive switch is unlocked, the central control worm gear 55 rotates counterclockwise, and the drive protrusion 551 rotates counterclockwise with the central control worm gear 55. The drive protrusion 551 extends into the push groove and presses against and pushes the inner right end face of the groove, so that the drive protrusion 551 pushes the drive rocker arm 2 to rotate. At this time, the worm gear reset component 56 is in a compressed state. At the same time, the worm gear reset component 56 applies an elastic force in the clockwise direction to the central control worm gear 55, so that the central control worm gear 55 reverses and drives the drive protrusion 551 to abut against the inner left end face of the push groove, thereby realizing the reset of the central control worm gear 55.

[0077] In some embodiments, the child lock mechanism 4 includes a drive worm gear 41 and a clutch linkage 42. The clutch linkage 42 is movably connected to the central rocker arm 3. The drive worm gear 41 is used to drive the clutch linkage 42 to move between the child lock closed state and the child lock open state. The central rocker arm 3 is adapted to push the clutch linkage 42 to drive the drive rocker arm 2 to unlock the car door when the clutch linkage 42 is in the child lock closed state.

[0078] In other words, during the relative movement of the clutch linkage 42 and the central rocker arm 3, the clutch linkage 42 and the drive rocker arm 2 have a child lock closed state and a child lock open state. When the clutch linkage 42 and the drive rocker arm 2 are in the child lock closed state, the central rocker arm 3 pushes the clutch linkage 42 to push the drive rocker arm 2 to rotate relative to the door lock housing 1, thereby unlocking the door.

[0079] Specifically, the drive worm gear 41 is located on the right side of the central rocker arm 3. A mounting post 11 is provided on the door lock housing 1. The drive worm gear 41 is provided with a mounting hole. The drive worm gear 41 can be rotatably mounted on the mounting post 11 through the mounting hole. The drive worm gear 41 is connected to the clutch linkage 42. The drive worm gear 41 is provided with a push port 411. The clutch linkage 42 is provided with a push protrusion 422. The push port 411 extends circumferentially along the drive worm gear 41. The push protrusion 422 extends into the push port 411. When the drive worm gear 41 rotates, the push port 411 presses against the push protrusion 422 to drive the clutch linkage 42 to move.

[0080] Therefore, when the drive worm gear 41 rotates, it can drive the clutch linkage 42 to move closer to or further away from the drive rocker arm 2. The clutch linkage 42 has two extreme positions. When the clutch linkage 42 moves to the right extreme position, it separates from the drive rocker arm 2, which is the child lock open state. When the clutch linkage 42 moves to the left extreme position, it contacts the drive rocker arm 2, which is the child lock closed state. Figure 7 This is a rear view of the child lock position. The rotation of the central rocker arm 3 drives the clutch linkage 42 to push the second push part 22 of the drive rocker arm 2 to rotate, thereby unlocking the car door.

[0081] And, when the child lock is in the unlocked state, such as Figure 8 The image shows the back view with the child lock engaged. The rotation of the central rocker arm 3 causes the clutch linkage 42 to fail to drive the drive rocker arm 2 to rotate, meaning the door cannot be unlocked via the central rocker arm 3. This renders the child lock unengaging ineffective and prevents the door from being unlocked by pulling it inward. Therefore, the door unlocking can be flexibly controlled based on the child lock mechanism 4's open state, making door unlocking safer and more reliable.

[0082] Furthermore, the clutch linkage 42 is also equipped with a switching spring 424, which is used to send the clutch linkage 42 to a predetermined position. That is, when the drive worm gear 41 drives the clutch linkage 42 to move, the switching spring 424 is responsible for pushing the clutch linkage 42 to the corresponding position, so as to realize the pressing cooperation between the clutch linkage 42 and the drive rocker arm 2, and the pressing is reliable and stable.

[0083] It should be noted that the driving worm gear 41 can be constructed as a sector-shaped worm gear, such as... Figure 1 As shown, the sector worm gear also meshes with the worm 62 for transmission, and the input end of the worm 62 is also connected to the drive motor 61. Thus, the forward and reverse rotation of the drive motor 61 can drive the sector worm gear to rotate in both directions, thereby realizing the opening and closing of the child lock mechanism 4.

[0084] In some embodiments, the central rocker arm 3 is provided with a first movable groove 31, and the clutch lever is provided with a first movable part 421. The first movable part 421 extends into the first movable groove 31 and is slidably engaged with the central rocker arm 3. The drive worm gear 41 is used to drive the clutch linkage 42 to drive the first movable part 421 to slide in the first movable groove 31. That is, by driving the clutch linkage 42 to move through the drive worm gear 41, the relative position of the first movable part 421 and the first movable groove 31 can be automatically switched, thereby switching the open state of the child lock mechanism 4.

[0085] Specifically, the clutch linkage 42 is located below the central rocker arm 3 and is slidably connected to the central rocker arm 3. In the front view, the rotation axis of the central rocker arm 3 is located on the left, and the first movable groove 31 of the central rocker arm 3 is located on the right. For example... Figure 7 and Figure 8 As shown, the first movable groove 31 can be constructed as a movable slide, the extension direction of which is the same as the movement trajectory of the clutch linkage 42, and the end of the clutch linkage 42 is provided with a first movable part 421, such as... Figure 3 As shown, the first movable part 421 can be constructed as a fixed column, which protrudes upwards. When the clutch linkage 42 is installed with the central rocker arm 3, the fixed column extends into the movable slide groove and slides. The other end of the clutch linkage 42 is connected to the drive worm gear 41. The drive worm gear 41 drives the fixed column to move along the movable slide groove in a direction away from the central rocker arm 3. At this time, as shown... Figure 8As shown, the child lock mechanism 4 is in the unlocked state. Conversely, the drive worm gear 41 can drive the fixed column to move along the movable slide groove towards the center rocker arm 3. At this time, as... Figure 7 As shown, the child lock mechanism 4 is in the child lock closed state.

[0086] The drive worm gear 41 is also equipped with a coaxially distributed drive spring 412, which applies an elastic force to the drive worm gear 41. That is, after the electric drive structure 6 drives the drive worm gear 41 to rotate, the drive spring 412 simultaneously applies an elastic force towards the drive worm gear 41, causing the drive worm gear 41 to rotate in the opposite direction and return to the neutral position. This reduces the need for the drive motor 61 in the child lock mechanism 4 to rotate and drive the drive worm gear 41 to reset, thus reducing the cost of the door lock assembly 100. Furthermore, the central rocker arm 3 is also equipped with a coaxially distributed first reset spring 33 for resetting after the central rocker arm 3 has moved, and the drive rocker arm 2 is equipped with a coaxially distributed second reset spring 23 for resetting after the drive rocker arm 2 has moved.

[0087] In some embodiments, the central rocker arm 3 is connected to an inner opening pull cable 32 for pulling the central rocker arm 3 to rotate. Specifically, the inner opening pull cable 32 is located at one end of the central rocker arm 3 and at the end opposite to the rotation axis of the central rocker arm 3, which facilitates the inner opening pull cable 32 to pull the central rocker arm 3 to rotate around its own rotation axis. Thus, when the child lock is engaged, pulling the inner opening pull cable 32 drives the central rocker arm 3 to rotate, thereby driving the push convex surface 423 of the clutch linkage 42 to push the drive rocker arm 2 to rotate, thus realizing the inner opening and unlocking of the car door.

[0088] Therefore, by driving the rocker arm 2 to unlock via the central rocker arm 3 and the pawl 51, and by driving the rocker arm 2 to unlock via the central control worm gear 55, three door unlocking methods can be achieved, allowing for flexible selection of door unlocking and improving the security of vehicle unlocking.

[0089] In some embodiments, the pawl assembly includes a pawl 51 and a pawl slider 52. The pawl 51 is rotatably mounted on the door lock housing 1, and the pawl slider 52 is movably mounted on the pawl 51 and rotates with the pawl 51. The pawl slider 52 is adapted to push the first pusher 21 when the lock is released, and the rotation trajectory of the pawl slider 52 about the rotation axis of the pawl 51 when the lock is engaged is offset from that of the first pusher 21.

[0090] In other words, when the door is unlocked, the pawl slider 52 rotates with the pawl 51 to push the first pusher 21, thereby unlocking the door. When the door is engaged, the trajectory of the pawl slider 52 rotating around the pawl 51 is offset from the first pusher 21, and the door cannot be unlocked. Thus, the door can be unlocked by switching between the pawl slider 52 and the first pusher 21.

[0091] Specifically, both the pawl 51 and the pawl slider 52 are movably mounted on the door lock housing 1. In the actual design, the pawl 51 has a mounting hole, through which it is mounted on the mounting post 11 of the door lock housing 1. The pawl 51 can rotate around the mounting post 11. The pawl slider 52 is movably connected to the upper side of the pawl 51, and the rotation of the pawl 51 can drive the pawl slider 52 to rotate. Thus, when the lock is released, if... Figure 6 As shown, after the pawl 51 rotates, it drives the pawl slider 52 to rotate. The pawl slider 52 pushes the first push part 21 to rotate, thereby driving the drive rocker arm 2 to rotate and unlock the car door.

[0092] And, when in an insured state, such as Figure 5 As shown, because the rotation trajectory of the pawl slider 52 is misaligned with that of the first pusher 21, the rotation of the pawl 51 drives the pawl slider 52 to rotate but cannot drive the rocker arm 2 to rotate. Therefore, the door cannot be unlocked by the pawl 51, and the locking mechanism is ineffective.

[0093] In some embodiments, the pawl slider 52 is slidably mounted on the pawl 51. The pawl slider 52 is provided with a first pushing surface 524. The pawl slider 52 is adapted to slide relative to the pawl so that the first pushing surface 524 presses against the first pushing part 21 or is offset from the first pushing part 21. Thus, when the pawl slider 52 slides back and forth relative to the pawl 51, the first pushing surface 524 can be switched to press against or be offset from the first pushing part 21 to switch the state of the central control mechanism 5.

[0094] Specifically, in actual design, such as Figure 5 As shown, a sliding groove 521 can be provided on the pawl slider 52. The fixing post 11 on the door lock housing 1 passes through the pawl 51 and the sliding groove 521, and the pawl 51 is slidably connected to the pawl through the sliding groove 521. The pawl slider 52 is provided with a first pushing surface 524, which is located close to the first pushing part 21. When the pawl assembly switches between the locked and unlocked states, it is achieved by the sliding of the pawl slider 52 relative to the pawl. The pawl 51 is the fixed end, and the pawl slider 52 slides relative to the pawl 51, and slides in the direction close to the first pushing part 21. When the first pushing surface 524 contacts and presses against the first pushing part 21, it is in the unlocked state. When it slides away from the first pushing part 21, the first pushing surface 524 is misaligned with the first pushing part 21, and it is in the locked state.

[0095] Therefore, by using the two relative positions of the first pushing surface 524 and the first pushing part 21, the door can be selectively unlocked, which helps to improve the reliability of door unlocking.

[0096] The pawl assembly also includes a pawl spring 54, which is mounted on the pawl slider 52. One end of the pawl spring 54 abuts against the pawl slider 52, and the other end presses against the door lock housing 1. The pawl spring 54 is used to apply an elastic force to the pawl slider 52 to move from the locked position to the unlocked position. The structure is simple and easy to switch.

[0097] In addition, the pawl 51 is also equipped with a third return spring 513 coaxially distributed, which is used to reset the pawl 51 after it is activated, so as to realize the reset after the door is pulled outward to unlock.

[0098] In some embodiments, the central control mechanism 5 further includes a locking link 531, which is movably mounted on the door lock housing 1. The locking link 531 is adapted to push the pawl slider 52 to move relative to the pawl 51 when moving relative to the door lock housing 1, so as to switch to the locked state. Thus, by moving the locking link 531, the pawl slider 52 can be pushed to the locked state, thereby realizing the switching of locking and unlocking of the central control mechanism 5.

[0099] Specifically, the locking link 531 is movably mounted on the door lock housing 1, and the locking link 531 can move left and right relative to the door lock housing 1, such as... Figure 3 As shown, a pushing boss 5311 is provided on the locking link 531 near the pawl slider 52. The locking link 531 has two extreme positions relative to the door lock housing 1. When the locking link 531 is at the right extreme position, the pawl slider 52 moves relative to the pawl 51 until the pawl slider 52 contacts the first pushing part 21 of the drive rocker arm 2. Figure 6 As shown, this is the unlocked state. When the locking linkage 531 moves from the right limit position to the left limit position, the push boss 5311 pushes the pawl slider 52, causing the pawl slider 52 to move relative to the pawl 51 until it is misaligned with the first push part 21 of the drive rocker arm 2, as shown. Figure 5 As shown, this is the in-safe state.

[0100] Therefore, by pushing the pawl slider 52 through the locking linkage 531, the central control mechanism 5 can be freely switched between unlocking and locking, thus making door unlocking ineffective when the lock is engaged.

[0101] The present invention also proposes a vehicle.

[0102] According to the vehicle of the present invention, a door lock assembly 100 of any of the above embodiments is provided. The cooperation between the central control mechanism 5, the drive rocker arm 2, the center rocker arm 3 and the child lock mechanism 4 can effectively unlock the drive rocker arm 2 when the central control is in the unlocked state and when the child lock is in the closed state. The door lock assembly 100 has fewer structural components, a shorter transmission chain and higher efficiency, thereby improving the reliability and durability of the door lock assembly 100. It also occupies less space, is lightweight and compact, and has stronger applicability.
