[0002] Some vehicle door locks currently feature an electric snap-in function. When the door is closed, the snap-in assembly drives the lock tongue to the first locking position, automatically locking the door. While these locks offer increased functionality and comfort compared to conventional door locks, they also present the risk of pinching hands or clothing. Therefore, an emergency release assembly is required. This assembly is manually operated to push the snap-in assembly away from the lock tongue, mechanically interrupting the automatic snap-in process. This allows the door to be quickly opened in an emergency, eliminating the danger.

[0072] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0073] Reference below Figures 1-19 A vehicle door lock according to an embodiment of the present invention is described.

[0074] The vehicle door lock 100 according to the embodiment of the present invention includes: a mounting bracket 10 , a bolt assembly 20 , a suction assembly 30 and an emergency release assembly 40 .

[0075] For example, the mounting bracket 10 includes a mounting plate 11 and a mounting shell 12 , and the mounting shell 12 and the mounting plate 11 are arranged along a third direction (eg, direction e3 in the drawings) and are cooperatively connected.

[0076] For example, the e3 direction may be an up-down direction.

[0077] The locking tongue assembly 20 is mounted on the mounting bracket 10 and includes a movable locking tongue 21. The locking tongue 21 is configured to engage with a locking ring on the vehicle body. For example, the mounting bracket 10 is mounted on the vehicle door, the locking tongue 21 is mounted on the mounting bracket 10, and the locking ring is mounted on the vehicle body. When the vehicle door is closed, the locking tongue 21 engages with the locking ring.

[0078] The suction assembly 30 is mounted on the mounting bracket 10 and includes a movable suction mechanism 31. The suction mechanism 31 includes a suction push arm 32 that can be separated from or abutted against the lock tongue 21. The suction push arm 32 is used to push the lock tongue 21 to a first locked position. For example, when the vehicle door needs to be suctioned, the suction push arm 32 abuts against the lock tongue 21, pushing the lock tongue 21 to the locked position, achieving the effect of automatically suctioning and closing the door. When the vehicle door does not need to be suctioned, the suction push arm 32 is separated from the lock tongue 21 to prevent the suction push arm 32 from interfering with the movement of the lock tongue 21.

[0079] For example, the lock tongue 21 is provided with an engaging protrusion 213 , and the engaging assembly 30 abuts against the engaging protrusion 213 , thereby pushing the lock tongue 21 to move to reach the locked position.

[0080] The emergency release assembly 40 is provided on the mounting bracket 10 and includes a movable emergency release push arm 41. The emergency release push arm 41 abuts against the suction push arm 32 to push the suction push arm 32 to move, so that the suction push arm 32 is separated from the lock tongue 21. By making the emergency release assembly 40 include a movable emergency release push arm 41, and making the emergency release push arm 41 able to push the suction push arm 32 to move, so that the suction mechanism 31 is separated from the lock tongue 21, the emergency release push arm 41 can interrupt the automatic suction process through mechanical pushing in an emergency situation, so that the car door can be opened smoothly and avoid danger. In addition, by providing the emergency release push arm 41 to directly abut against and push the suction push arm 32, the number of transmission components in the car door lock 100 can be reduced, the structure is simple, and the risk of jamming and failure can be reduced.

[0081] The movement of the emergency disengagement push arm 41 pushes the engagement push arm 32 to move so that the engagement mechanism 31 is separated from the lock tongue 21 , which is achieved by manually pushing the emergency disengagement push arm 41 .

[0082] For example, when the suction component 30 fails or an emergency occurs, the emergency disengagement push arm 41 moves and abuts against the suction push arm 32. At this time, the emergency disengagement push arm 41 can push the suction push arm 32 to move away from the lock tongue 21, so that the suction push arm 32 is separated from the lock tongue 21. The suction push arm 32 no longer interferes with the movement of the lock tongue 21. The lock tongue 21 can be unlocked by the mechanical structure and move freely, so that the lock tongue 21 is separated from the lock ring, and the car door can be opened freely.

[0083] According to the vehicle door lock 100 of the embodiment of the present invention, by providing an emergency disengagement component 40, the emergency disengagement component 40 can push the suction mechanism 31 to move to separate from the lock tongue 21, and the automatic suction process can be interrupted by mechanical push, so that the vehicle door can be quickly opened in an emergency, thereby realizing the emergency disengagement function; and the emergency disengagement push arm 41 of the emergency disengagement component 40 is in direct contact with the suction push arm 32 of the suction mechanism 31 to directly push the suction push arm 32 to move, thereby separating the suction mechanism 31 from the lock tongue 21, which can simplify the transmission path and transmission relationship between the emergency disengagement component 40 and the suction component 30, so that the vehicle door can be opened smoothly, is less likely to get stuck and fail, and can improve the reliability of the emergency disengagement function; and, the vehicle door lock 100 has fewer transmission components and a simpler structure.

[0084] According to some embodiments of the present invention, referring to Figure 7-12 The emergency disengagement push arm 41 has an emergency disengagement guide surface 46, which is used to abut or separate from the suction push arm 32. The motion trajectory formed in the process of the suction push arm 32 pushing the lock tongue 21 to the first locking position is the suction motion trajectory. At least a portion of the emergency disengagement guide surface 46 extends along the extension direction of the suction motion trajectory. By making at least a portion of the emergency disengagement guide surface 46 extend along the extension direction of the suction motion trajectory, it can be ensured that during the emergency disengagement process, no matter where the suction push arm 32 is located on the suction motion trajectory, the emergency disengagement push arm 41 can push the suction push arm 32 to move after pushing the same distance, so that the suction push arm 32 is separated from the lock tongue 21, so that the emergency disengagement push arm 41 can more fully and accurately push the suction push arm 32 to move, and the normal operation of the emergency disengagement assembly 40 can be fully guaranteed in an emergency situation.

[0085] According to some embodiments of the present invention, referring to Figure 7-12 The emergency disengagement push arm 41 has an emergency disengagement guide surface 46, which is used to abut or separate from the suction push arm 32. The projection of the emergency disengagement guide surface 46 on the reference surface is a first projection. The reference surface is perpendicular to the rotation axis of the suction push arm 32. The motion trajectory formed in the process of the suction push arm 32 pushing the lock tongue 21 to the first locking position is the suction motion trajectory. At least a portion of the first projection is the same as at least a portion of the suction motion trajectory. By making at least a portion of the first projection and at least a portion of the suction motion trajectory have the same shape, it can be ensured that during the emergency disengagement process, no matter where the suction push arm 32 is located on the suction motion trajectory, the emergency disengagement push arm 41 can push the suction push arm 32 to move after pushing the same distance, so that the suction push arm 32 is separated from the lock tongue 21, so that the emergency disengagement push arm 41 can more fully and accurately push the suction push arm 32 to move, and the normal operation of the emergency disengagement assembly 40 can be fully guaranteed in an emergency situation.

[0086] For example, the rotation axis of the suction push arm 32 extends along the third direction.

[0087] According to some embodiments of the present invention, referring to Figure 3-Figure 7 The emergency release assembly 40 includes an emergency release reset member 51, which is used to drive the emergency release push arm 41 to reset and separate from the suction push arm 32. By using the emergency release reset member 51 to drive the emergency release push arm 41 to reset, the emergency release push arm 41 can be returned to its original position and separated from the suction push arm 32 under the action of the emergency release reset member 51 when no force is applied, thereby preventing the emergency release push arm 41 from continuously abutting against the suction push arm 32, thereby preventing the suction function of the suction assembly 30 from failing.

[0088] According to some embodiments of the present invention, referring to Figures 9-12 The emergency release push arm 41 is movable along a first direction (e.g., direction e1 in the accompanying drawings) between a first position 411 and a second position 412 to abut or separate from the suction push arm 32. In the first position 411, the emergency release push arm 41 is separated from the suction push arm 32. When an emergency or malfunction occurs, the emergency release push arm 41 moves along the first direction from the first position 411 to the second position 412. The emergency release push arm 41 abuts against the suction push arm 32, causing the suction push arm 32 to disengage from the lock tongue 21. The lock tongue 21 no longer interferes with movement. The lock tongue 21 can be mechanically unlocked and freely move, separating the lock tongue 21 from the lock ring, allowing the vehicle door to be opened freely. When no force is applied to the emergency release push arm 41, the emergency release push arm 41 moves from the second position 412 to the first position 411, separating from the suction push arm 32. The emergency release push arm 41 no longer abuts against or interferes with movement of the suction push arm 32.

[0089] According to some embodiments of the present invention, referring to Figure 3-Figure 6 The emergency release push arm 41 includes a push arm main section 42 and a contact section 43. The push arm main section 42 extends in a long strip shape in a first direction. The contact section 43 is connected to one side of the push arm main section 42 along the first direction and extends in a second direction (e.g., direction e2 in the accompanying drawings). The contact section 43 abuts or separates from the suction push arm 32. At least a portion of the position-limiting pressing portion 62 contacts the push arm main section 42, and at least a portion of the position-limiting pressing portion 62 contacts the contact section 43. By ensuring that at least a portion of the position-limiting pressing portion 62 contacts the push arm main section 42 and at least a portion of the position-limiting pressing portion 62 contacts the contact section 43, the position-limiting pressing portion 62 can fully limit the position of both the push arm main section 42 and the contact section 43, thereby more effectively preventing the emergency release push arm 41 from moving and displacing, resulting in failure of the emergency release function. Furthermore, the warping deformation of the emergency release push arm 41 during operation can be more effectively reduced.

[0090] For example, the limiting pressing portion 62 includes a first pressing portion 63 , and the first pressing portion 63 contacts the push arm main section 42 .

[0091] For example, the contact segment 43 includes a pressing protrusion 49 , and the position-limiting pressing portion 62 includes a second pressing portion 64 . The second pressing portion 64 contacts the pressing protrusion 49 to limit the position of the contact segment 43 .

[0092] According to some embodiments of the present invention, referring to Figure 7 The emergency disengagement push arm 41 has an emergency disengagement guide surface 46, which is used to abut or separate from the suction push arm 32. The emergency disengagement push arm 41 is provided with an auxiliary protrusion 47, which has an auxiliary guide surface 48. The auxiliary guide surface 48 is located on one side of the emergency disengagement guide surface 46 along the second direction, where the second direction intersects the first direction. By providing the emergency disengagement push arm 41 with the auxiliary protrusion 47 and the auxiliary guide surface 48, the emergency disengagement push arm 41 can more fully abut against the suction push arm 32.

[0093] According to some embodiments of the present invention, referring to Figures 9-12 By making the movement of the emergency disengagement push arm 41 a linear motion, it is possible to ensure that during the emergency disengagement process, no matter where the suction push arm 32 is located on the suction motion trajectory, the emergency disengagement push arm 41 can push the suction push arm 32 to move after moving along the linear motion, so that the suction push arm 32 is separated from the lock tongue 21, so that the emergency disengagement push arm 41 can more fully and accurately push the suction push arm 32 to move, and the normal operation of the emergency disengagement assembly 40 can be fully guaranteed in an emergency situation.

[0094] According to some embodiments of the present invention, referring to Figure 3-Figure 6 The emergency release assembly 40 includes a central rotating arm 52, which is rotatably connected to the mounting bracket 10. One end of the emergency release push arm 41 is connected to the central rotating arm 52, and the other end of the emergency release push arm 41 abuts or separates from the suction push arm 32. The central rotating arm 52 is used to drive the emergency release push arm 41 to move between the first position and the second position 412. By making the emergency release assembly 40 include the central rotating arm 52 and making the central rotating arm 52 rotatably connected to the mounting bracket 10, and one end of the emergency release push arm 41 is connected to the central rotating arm 52, the central rotating arm 52 can drive the emergency release push arm 41 to move in the first direction during rotation, converting the sliding movement of the emergency release push arm 41 into rotational movement, making it easier to connect to the rotation handle and improving ease of use.

[0095] According to some embodiments of the present invention, referring to Figure 9The emergency disengagement push arm 41 is provided with a guide hole 44, and the intermediate transfer arm 52 is provided with a guide post 53. The guide post 53 is inserted into the guide hole 44 and is movable relative to the guide hole 44 in a second direction (e.g., direction e2 in the accompanying drawings). The second direction, the first direction, and the direction of the rotation axis of the intermediate transfer arm 52 intersect with each other. During the rotation of the intermediate transfer arm 52, the guide post 53 is displaced in both the first and second directions. By inserting the guide post 53 into the guide hole 44 and being movable relative to the guide hole 44 in the second direction, the movement of the guide post 53 relative to the guide hole 44 in the second direction can compensate for the displacement of the guide post 53 in the second direction during the rotation of the intermediate transfer arm 52. The emergency disengagement push arm 41 can be moved only in the first direction and fixed in the second direction, so that the emergency disengagement push arm 41 can more stably push the suction push arm 32 to move, and the normal operation of the emergency disengagement assembly 40 can be fully guaranteed in an emergency.

[0096] For example, the rotation axis of the middle rotating arm 52 may extend along a third direction (eg, direction e3 in the drawings).

[0097] According to some embodiments of the present invention, the guide post 53 is a cylinder, and the length of the guide hole 44 in the second direction is greater than the diameter of the guide post 53. By making the guide post 53 a cylinder, interference between the guide post 53 and the side wall of the guide hole 44 during the rotation of the intermediate arm 52 can be avoided, resulting in the intermediate arm 52 not rotating properly. In an emergency, the normal operation of the emergency release assembly 40 can be fully guaranteed. By making the length of the guide hole 44 in the second direction greater than the diameter of the guide post 53, the guide post 53 can be more fully moved relative to the guide hole 44 in the second direction, compensating for the displacement of the guide post 53 in the second direction during the rotation of the intermediate arm 52. The emergency release push arm 41 can be moved only in the first direction and fixed in the second direction, so that the emergency release push arm 41 can more stably push the suction push arm 32 to move. In an emergency, the normal operation of the emergency release assembly 40 can be more fully guaranteed.

[0098] According to some embodiments of the present invention, referring to Figure 1The emergency release assembly 40 includes: a central rotating arm shaft 50 and an emergency release reset member 51. The central rotating arm shaft 50 is fixed to the mounting bracket 10. The central rotating arm 52 rotates around the central rotating arm shaft 50. The emergency release reset member 51 is sleeved on the outer peripheral side of the central rotating arm shaft 50 and is used to drive the central rotating arm 52 to reset, so that the emergency release push arm 41 is reset to the first position 411. The two ends of the emergency release reset member 51 are respectively connected to the central rotating arm 52 and the mounting bracket 10. One end of the emergency release reset member 51 abuts or is connected to the central rotating arm 52, and the other end of the emergency release reset member 51 abuts or is connected to the mounting bracket 10. By sleeved the emergency disengagement reset member 51 on the outer peripheral side of the intermediate transfer arm shaft 50 and used to drive the intermediate transfer arm 52 to reset, when the intermediate transfer arm 52 is not subjected to the force, the intermediate transfer arm 52 resets and rotates under the action of the emergency disengagement reset member 51, and the emergency disengagement push arm 41 moves from the second position 412 to the first position 411, separating from the suction push arm 32, and the emergency disengagement push arm 41 no longer abuts against and interferes with the movement of the suction push arm 32.

[0099] For example, the force of the emergency disengagement reset member 51 can drive the middle transfer arm 52 to rotate counterclockwise, causing the guide column 53 to move along the second direction relative to the guide hole 44 toward the middle transfer arm shaft 50, pulling the emergency disengagement push arm 41 to move along the first direction toward the guide column 53, and the emergency disengagement push arm 41 disengages from the abutment with the suction push arm 32.

[0100] According to some embodiments of the present invention, the emergency disengagement assembly 40 includes an emergency disengagement rocker arm 54, which is rotatably provided on the mounting bracket 10, and the emergency disengagement rocker arm 54 abuts against the intermediate arm 52 to push the intermediate arm 52 to rotate. In the event of an emergency or a malfunction, the user can shake the emergency disengagement rocker arm 54 to rotate the emergency disengagement rocker arm 54, and the emergency disengagement rocker arm 54 abuts against the intermediate arm 52 and pushes the intermediate arm 52 to rotate, and the intermediate arm 52 drives the emergency disengagement push arm 41 to move along the first direction to the second position 412, and the emergency disengagement push arm 41 abuts against the suction push arm 32 and pushes the suction push arm 32 to rotate, and the suction push arm 32 is separated from the lock tongue 21, so that the lock tongue 21 can be unlocked by the mechanical structure and move freely, so that the lock tongue 21 is separated from the lock ring, and the car door can be opened freely.

[0101] For example, an emergency release rocker is provided on the inside of the vehicle door, and the emergency release rocker is connected to the emergency release rocker arm 54 to drive the emergency release rocker arm 54 to rotate; for another example, an emergency release rocker is provided on the outside of the vehicle door, and the emergency release rocker is connected to the emergency release rocker arm 54 to drive the emergency release rocker arm 54 to rotate; for another example, emergency release rockers are provided on both the inside and outside of the vehicle door, and the emergency release rockers on the inside and outside of the vehicle door can be connected to the emergency release rocker arm 54 to drive the emergency release rocker arm 54 to rotate.

[0102] According to some embodiments of the present invention, referring to Figure 3 The mounting bracket 10 is provided with a guide groove 14, in which at least a portion of the emergency release push arm 41 is received. The guide groove 14 is used to guide the movement of the emergency release push arm 41. By partially receiving the emergency release push arm 41 in the guide groove 14, the emergency release push arm 41 can slide along the guide direction of the guide groove 14, thereby preventing the emergency release push arm 41 from shifting and causing the emergency release function to fail.

[0103] For example, the push arm body section 42 of the emergency release push arm 41 is accommodated in the guide groove 14 .

[0104] For example, the mounting bracket 10 includes a mounting plate 11 and a mounting shell 12, which are arranged along a third direction and are matingly connected to the mounting plate 11. The mounting shell 12 is provided with a plurality of mounting protrusions 15 and mounting baffles 16, which together define a guide slot 14.

[0105] According to some embodiments of the present invention, referring to Figure 3-Figure 6 The door lock 100 further includes a limiting pressure plate 60 connected to the mounting bracket 10. At least a portion of the limiting pressure plate 60 is located on the side of the emergency release push arm 41 away from the mounting bracket 10 to limit the position of the emergency release push arm 41. By including the limiting pressure plate 60 in the door lock 100, and at least a portion of the limiting pressure plate 60 being located on the side of the emergency release push arm 41 away from the mounting bracket 10, the limiting pressure plate 60 and the mounting bracket 10 can cooperate to limit the position of the emergency release push arm 41 in the third direction, thereby preventing the emergency release push arm 41 from moving and causing the emergency release function to fail. In addition, the warping deformation of the emergency release push arm 41 during operation can be reduced.

[0106] For example, refer to Figure 7 and Figure 18 The mounting bracket 10 includes a mounting plate 11 and a mounting shell 12. The mounting shell 12 is arranged along the third direction and is matingly connected to the mounting plate 11. The mounting shell 12 is provided with a plurality of mounting protrusions 15. Correspondingly, the position-limiting pressure plate 60 is provided with a plurality of mounting openings 61. The mounting protrusions 15 are received in the mounting openings 61, thereby securing the position-limiting pressure plate 60 to the mounting shell 12.

[0107] For example, refer to Figure 6 An avoidance recess 45 is provided on the emergency disengagement push arm 41. The avoidance recess 45 is used to avoid part of the structure of the limit pressure plate 60 to avoid interference between the emergency disengagement push arm 41 and the limit pressure plate 60 during movement.

[0108] According to some embodiments of the present invention, referring to Figure 2-Figure 8The limiting pressure plate 60 includes a limiting pressing portion 62, which contacts the emergency release push arm 41 to limit the position of the emergency release push arm 41. By making the limiting pressure plate 60 include multiple limiting pressing portions 62 arranged at intervals, the limiting pressing portions 62 can abut against the emergency release push arm 41 along the third direction, preventing the emergency release push arm 41 from moving relative to the limiting pressure plate 60 in the third direction. This can further effectively prevent the emergency release push arm 41 from moving and displacing, thereby preventing the emergency release function from failing. In addition, the warping deformation of the emergency release push arm 41 during operation can be further reduced.

[0109] According to some embodiments of the present invention, referring to Figure 2-Figure 6 The emergency release push arm 41 includes a push arm main section 42 and a contact section 43. The contact section 43 is connected to the push arm main section 42. The contact section 43 abuts or separates from the pull-in push arm 32. At least a portion of the position-limiting and pressing portion 62 contacts the push arm main section 42, and at least a portion of the position-limiting and pressing portion 62 contacts the contact section 43. By ensuring that at least a portion of the position-limiting and pressing portion 62 contacts the push arm main section 42 and at least a portion of the position-limiting and pressing portion 62 contacts the contact section 43, the position-limiting and pressing portion 62 can fully limit the position of both the push arm main section 42 and the contact section 43, thereby more effectively preventing the emergency release push arm 41 from shifting and causing the emergency release function to fail. Furthermore, the warping and deformation of the emergency release push arm 41 during operation can be more effectively reduced.

[0110] For example, the limiting pressing portion 62 includes a first pressing portion 63 , and the first pressing portion 63 contacts the push arm main section 42 .

[0111] For example, the contact segment 43 includes a pressing protrusion 49 , and the position-limiting pressing portion 62 includes a second pressing portion 64 . The second pressing portion 64 contacts the pressing protrusion 49 to limit the position of the contact segment 43 .

[0112] According to some embodiments of the present invention, referring to Figure 15 The suction mechanism 31 includes a suction rocker arm 35, and the suction assembly 30 includes an actuator assembly 80. The suction rocker arm 35 is rotatably connected to the mounting bracket 10. The suction push arm 32 is rotatably connected to the suction rocker arm 35. The actuator assembly 80 is connected to the suction rocker arm 35 to drive the suction rocker arm 35 to rotate. By making the suction mechanism 31 include a rotatable suction rocker arm 35 and making the suction push arm 32 rotatably connected to the suction rocker arm 35, the suction mechanism 31 can be simplified and can achieve that the suction mechanism 31 can more stably push the lock tongue 21 to move to the first locking position.

[0113] According to some embodiments of the present invention, referring to Figure 14 and Figure 15The suction mechanism 31 includes a suction rocker arm 35, which is rotatably connected to the mounting bracket 10, an actuator assembly 80 is connected to the suction rocker arm 35 to drive the suction rocker arm 35 to rotate, and a suction push arm 32 is rotatably connected to the suction rocker arm 35. By rotatably connecting the suction rocker arm 35 to the mounting bracket 10, the suction mechanism 31 can be fixed on the mounting bracket 10 to prevent the suction assembly 30 from moving and causing the suction function to fail; by rotatably connecting the suction rocker arm 35 to the mounting bracket 10 and the suction push arm 32 to the suction rocker arm 35, the movement of the suction push arm 32 in the suction mechanism 31 can be made more flexible. When the emergency disengagement push arm 41 abuts and pushes the suction push arm 32 to move, the suction push arm 32 can rotate relative to the suction rocker arm 35 to disengage from the lock tongue 21.

[0114] According to some embodiments of the present invention, referring to Figure 15 The suction assembly 30 includes a suction rocker arm reset member 37, which is used to drive the suction rocker arm 35 to reset. One end of the suction rocker arm reset member 37 abuts or is connected to the suction rocker arm 35, and the other end of the suction rocker arm reset member 37 abuts or is connected to the mounting bracket 10. By making the suction assembly 30 include the suction rocker arm reset member 37, the suction rocker arm reset member 37 is sleeved on the outer peripheral side of the suction rocker arm rotating shaft 36 and is used to drive the suction rocker arm 35 to reset, the suction rocker arm 35 can automatically rotate under the elastic action of the suction rocker arm reset member 37 when not driven by the driving mechanism, driving the suction push arm 32 away from the lock tongue 21, and preventing the suction assembly 30 from continuously pushing and abutting the lock tongue 21, causing the lock tongue 21 to become stuck.

[0115] For example, the attraction rocker arm shaft 36 may extend along the third direction.

[0116] According to some embodiments of the present invention, referring to Figure 15 The suction assembly 30 includes a suction push arm reset member 39, which is used to drive the suction push arm 32 to reset. One end of the suction push arm reset member 39 abuts or is connected to the suction push arm 32, and the other end of the suction push arm reset member 39 abuts or is connected to the mounting bracket 10 or the suction rocker arm 35. By having the suction push arm reset member 39 sleeved on the outer peripheral side of the suction push arm rotating shaft 38 and used to drive the suction push arm 32 to reset, when the suction rocker arm 35 is not driven by the driving mechanism and is reset, the suction push arm 32 can be moved away from the lock tongue 21 under the action of the suction push arm reset member 39, thereby preventing the suction assembly 30 from continuously pushing and abutting the lock tongue 21, causing the lock tongue 21 to become stuck.

[0117] For example, the suction push arm shaft 38 may extend along the third direction.

[0118] According to some embodiments of the present invention, referring to Figure 9The suction push arm 32 includes a suction push arm plate 33 and a matching post 34. The matching post 34 is fixed to the suction push arm plate 33. The suction push arm plate 33 is rotatably connected to the suction rocker arm 35. The suction push arm plate 33 is used to abut or separate from the lock tongue 21, and the emergency release push arm 41 abuts or separates from the matching post 34. By making the emergency release push arm 41 abut or separate from the matching post 34, it is possible to prevent the impact of the emergency release push arm 41 on the suction push arm plate 33 from causing wear. This ensures that the suction push arm plate 33 has sufficient accuracy when abutting or separating from the lock tongue 21, and accurately pushes the lock tongue 21 to move during the suction process.

[0119] According to some embodiments of the present invention, referring to Figure 18 The mounting bracket 10 is provided with a guide structure 13, and the matching column 34 cooperates with the guide structure 13 to guide the movement of the suction push arm 32. By providing the guide structure 13 on the mounting bracket 10 and making the matching column 34 cooperate with the guide structure 13, the guide structure 13 can guide the suction push arm 32 to move along the suction movement trajectory, so that the suction push arm 32 can more accurately push the lock tongue 21 to close and lock the vehicle door during the suction process.

[0120] According to some embodiments of the present invention, referring to Figure 15 The suction assembly 30 includes: a suction rocker arm shaft 36, a suction push arm shaft 38, a suction rocker arm reset member 37 and a suction push arm reset member 39. The suction rocker arm shaft 36 is fixed to the mounting bracket 10. The suction rocker arm 35 is rotatably connected to the suction rocker arm shaft 36. The suction rocker arm reset member 37 is sleeved on the outer peripheral side of the suction rocker arm shaft 36 and is used to drive the suction rocker arm 35 to reset. The two ends of the suction rocker arm reset member 37 are respectively connected to the mounting bracket 10 and the suction rocker arm 35. The suction push arm shaft 38 is fixed to the suction rocker arm 35. The suction push arm reset member 39 is sleeved on the outer peripheral side of the suction push arm shaft 38 and is used to drive the suction push arm 32 to reset. The two ends of the suction push arm reset member 39 are respectively connected to the suction rocker arm shaft 36 and the suction push arm 32. By making the suction assembly 30 include a suction rocker arm reset member 37, the suction rocker arm reset member 37 is mounted on the outer peripheral side of the suction rocker arm shaft 36 and is used to drive the suction rocker arm 35 to reset, the suction rocker arm 35 can be automatically rotated under the elastic action of the suction rocker arm reset member 37 when not driven by the driving mechanism, driving the suction push arm 32 away from the lock tongue 21, thereby preventing the suction assembly 30 from continuously pushing and abutting the lock tongue 21 and causing the lock tongue 21 to become stuck. By making the suction push arm reset member 39 be mounted on the outer peripheral side of the suction push arm shaft 38 and is used to drive the suction push arm 32 to reset, when the suction rocker arm 35 is not driven by the driving mechanism and is reset, the suction push arm 32 can be moved away from the lock tongue 21 under the action of the suction push arm reset member 39, thereby preventing the suction assembly 30 from continuously pushing and abutting the lock tongue 21 and causing the lock tongue 21 to become stuck.

[0121] For example, the mounting bracket 10 is provided with a guide structure 13, one side of the mating column 34 is mated with the guide structure 13, and the suction push arm reset member 39 is sleeved on the outer circumference of the suction push arm shaft 38 and is used to drive the suction push arm 32 to reset. The two ends of the suction push arm reset member 39 are respectively connected to the suction rocker arm shaft 36 and the suction push arm 32. The suction push arm 32 can be pressed against the guide structure 13 under the elastic action of the suction push arm reset member 39, so that the suction push arm 32 can move along the path guided by the guide structure 13, so that the suction push arm 32 can more accurately push the lock tongue 21 to close and lock the vehicle door during the suction process.

[0122] For example, the door lock 100 further includes a limiting pressure plate 60, which is fixedly connected to the mounting plate 11. The pull-in rocker arm reset member 37 has a U-shaped end and an L-shaped end. The U-shaped end of the pull-in rocker arm reset member 37 is sleeved around the pull-in rocker arm 35, while the L-shaped end is fixed to the limiting pressure plate 60. When the pull-in rocker arm 35 is not driven by the drive mechanism, the pull-in rocker arm reset member 37 drives the pull-in rocker arm 35 to rotate clockwise about the pull-in rocker arm rotation axis 36, thereby resetting the pull-in rocker arm 35.

[0123] For example, one end of the suction push arm reset member 39 abuts against the suction rocker arm shaft 36, and the other end abuts against the matching column 34. The suction push arm reset member 39 drives the suction push arm 32 to rotate counterclockwise around the suction push arm shaft 38, so that the matching column 34 abuts against the guide structure 13.

[0124] According to some embodiments of the present invention, the lock tongue 21 is rotatably connected to the mounting bracket 10, and the lock tongue assembly 20 includes a lock tongue reset member 23. One end of the lock tongue reset member 23 abuts or is connected to the lock tongue 21, and the other end of the lock tongue reset member 23 abuts or is connected to the mounting bracket 10. The lock tongue reset member 23 is used to drive the lock tongue 21 to reset. By having the lock tongue assembly 20 include the lock tongue reset member 23, and the lock tongue reset member 23 is used to drive the lock tongue 21 to reset, the vehicle door can be opened and the lock tongue 21 can be rotated and reset without being constrained, thereby facilitating the engagement of the lock tongue 21 with the lock ring.

[0125] For example, the lock tongue assembly 20 includes a lock tongue shaft 22 and a lock tongue reset member 23. The lock tongue shaft 22 is fixed to the mounting bracket 10. The lock tongue 21 is rotatably connected to the lock tongue shaft 22. The lock tongue shaft 22 can extend along the third direction.

[0126] For example, the mounting bracket 10 includes a mounting plate 11 and a mounting shell 12, with the mounting shell 12 and the mounting plate 11 arranged along a third direction and matingly connected. A bolt reset member 23 has one end connected to the bolt 21 and the other end connected to the mounting plate 11. When the bolt assembly 20 is free of restraining forces, the elastic force of the bolt reset member 23 drives the bolt assembly 20 to rotate clockwise, facilitating mating of the bolt 21 with the lock ring.

[0127] According to some embodiments of the present invention, referring to Figure 13 and Figure 17 The lock tongue 21 has a release position, a second locking position, and a first locking position. The lock tongue 21 is driven as the vehicle door moves, so that the lock tongue 21 moves from the release position to the second locking position. The suction mechanism 31 is used to drive the lock tongue 21 from the second locking position to the first locking position. By using the lock ring to drive the lock tongue 21 from the release position to the second locking position, and the suction mechanism 31 to drive the lock tongue 21 from the second locking position to the first locking position, when the vehicle door is closed and the lock tongue 21 is in the second locking position, the suction assembly 30 automatically drives the lock tongue 21 from the second locking position to the first locking position, and closes the vehicle door by suction, avoiding the door being easily damaged due to the need to force the door to be closed, thereby improving comfort.

[0128] According to some embodiments of the present invention, a vehicle door lock includes a locking arm assembly 70, which is mounted on a mounting bracket 10 and includes a rotatable locking arm 71. The locking arm 71 is used to limit the position of the lock tongue 21. By limiting the position of the lock tongue 21 by the locking arm assembly 71, the lock tongue 21 can be prevented from slipping from a first locked position to a second locked position or a released position, thereby preventing the door from opening abnormally, and ensuring stable door closure.

[0129] According to some embodiments of the present invention, referring to Figure 13 and Figure 17 The lock tongue 21 has a second abutting surface 24 and a first abutting surface 25, and the locking arm 71 has a locking surface 72. In the released position, the lock tongue 21 is adapted to release the lock ring. In the second locked position, the lock tongue 21 is adapted to cooperate with the lock ring, and the second abutting surface 24 abuts the locking surface 72. In the first locked position, the lock tongue 21 is adapted to cooperate with the lock ring, and the first abutting surface 25 abuts the locking surface 72. By making the second abutting surface 24 abut the locking surface 72 when the lock tongue 21 is in the second locked position, it is possible to prevent the lock tongue 21 from sliding from the second locked position to the released position, causing the door to fail to close. By making the first abutting surface 25 abut the locking surface 72 when the lock tongue 21 is in the first locked position, it is possible to prevent the lock tongue 21 from sliding from the first locked position to the second locked position or the released position, causing the door to open abnormally, and ensure stable door closing.

[0130] For example, the lock tongue 21 has a lock ring abutting surface 214 . When the vehicle door is closed, the lock ring contacts the lock ring abutting surface 214 of the lock tongue 21 and pushes the lock tongue 21 to move.

[0131] When the door is opened and closed, the lock tongue 21 is first in the released position. The lock ring penetrates the lock tongue 21 and drives the lock tongue 21 to rotate until the locking surface 72 of the locking arm 71 abuts the second abutting surface 24. At this time, the lock tongue 21 is in the second locked position. The suction assembly 30 automatically drives the lock tongue 21 to continue moving until the first abutting surface 25 abuts the locking surface 72. At this time, the lock tongue 21 is in the first locked position and the door is closed stably.

[0132] According to some embodiments of the present invention, referring to Figure 12 The locking arm assembly 70 includes a locking arm reset member 74. One end of the locking arm reset member 74 abuts or is connected to the locking arm 71, and the other end of the locking arm reset member 74 abuts or is connected to the mounting bracket 10. The locking arm reset member 74 is used to bring the locking arm 71 into contact with the lock tongue 21 to limit the position of the lock tongue 21. By including the locking arm reset member 74 in the locking arm assembly 70, the locking arm reset member 74 can drive the locking arm 71 to rotate, causing the locking surface 72 to abut and engage with the lock tongue 21 when the lock tongue 21 is in the second locking position or the first locking position. This prevents the locking surface 72 from being disengaged from the lock tongue 21 due to the rotation of the locking arm 71, thereby ensuring stable and reliable closing of the vehicle door.

[0133] According to some embodiments of the present invention, referring to Figure 12 The locking arm assembly 70 includes a locking arm shaft 73 and a locking arm reset member 74. The locking arm shaft 73 is fixed to the mounting bracket 10. The locking arm 71 is rotatably connected to the locking arm shaft 73. The locking arm reset member 74 is sleeved on the outer circumference of the locking arm shaft 73 and is used to drive the locking arm 71 to reset. The two ends of the locking arm reset member 74 are respectively connected to the locking arm 71 and the mounting bracket 10. By making the locking arm assembly 70 include the locking arm reset member 74, which is sleeved on the outer circumference of the locking arm shaft 73 and is used to drive the locking arm 71 to reset, the locking arm reset member 74 can drive the locking arm 71 to rotate, so that the locking surface 72 and the lock tongue 21 are abutted and engaged when the lock tongue 21 is in the second locking position or the first locking position, thereby preventing the locking surface 72 and the lock tongue 21 from being disengaged due to the rotation of the locking arm 71, thereby ensuring stable and reliable closing of the vehicle door.

[0134] For example, the locking arm shaft 73 may extend along the third direction.

[0135] Reference Figure 13 and Figure 14When the vehicle door is in the process of being opened and closed, the lock tongue 21 is first located in the released position, and the lock ring invades the lock tongue 21 from the lock ring abutment surface 214 of the lock tongue 21 and drives the lock tongue 21 to rotate counterclockwise around the lock tongue rotation axis 22. During this process, the locking arm reset member 74 drives the locking arm 71 to rotate counterclockwise around the locking arm rotation axis 73, so that the locking arm 71 continues to abut against the lock tongue 21 until the locking surface 72 of the locking arm 71 abuts against the second abutment surface 24. At this time, the lock tongue 21 is in the second locked position.

[0136] When the lock tongue 21 is in the second locking position, the actuator assembly 80 drives the suction rocker arm 35 to rotate clockwise around the suction rocker arm shaft 36, and the suction rocker arm 35 drives the suction push arm 32 to move. The suction push arm 32 rotates counterclockwise around the suction push arm shaft 38 under the action of the suction push arm reset member 39 and makes the matching column 34 abut against the guide structure 13, and the suction push arm plate 33 moves along the guided path, and the suction push arm plate 33 abuts against the suction protrusion 213 of the lock tongue 21, and the suction push arm plate 33 drives the lock tongue 21 to move counterclockwise until the first abutting surface 25 of the lock tongue 21 abuts against the locking surface 72. At this time, the lock tongue 21 is in the first locking position and the car door is closed stably.

[0137] When the lock tongue 21 rotates from the second locking position to the first locking position, if an emergency occurs, the user can shake the emergency release rocker inside or outside the vehicle to drive the emergency release rocker arm 54, causing the emergency release rocker arm 54 to rotate. The emergency release rocker arm 54 abuts against the intermediate transfer arm 52 and pushes the intermediate transfer arm 52 to rotate.
