When the door is rotated to the closed position, the suction component is controlled to push the lock tongue component, causing the lock tongue component to continue to rotate to the fully closed state, making the door more reliably locked in the closed position and allowing it to be closed more gently, improving comfort.

[0003] In the related art, in order to guide the movement path of the suction component, a sliding groove structure is usually provided on the mounting bracket to form a guide structure to guide the suction component. Specifically, the end of the suction push arm of the suction component is accommodated in the above-mentioned sliding groove structure, and the suction push arm moves along the extension path of the sliding groove. However, in the process of guiding the suction push arm of the suction component by using the sliding groove guide structure, the suction process is unstable, resulting in inadequate suction execution.

[0077] 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.

[0078] Reference below Figures 1-15 A vehicle door lock 100 , a vehicle door, and a vehicle according to an embodiment of the present invention are described.

[0079] The vehicle door lock 100 according to the first embodiment of the present invention includes: a mounting bracket 10 , a lock tongue assembly 20 , and a suction assembly 30 .

[0080] The mounting bracket 10 is provided with a guide surface 131 that guides the suction assembly 30 along a predetermined path. For example, the mounting bracket 10 includes a mounting plate 11 and a mounting shell 12. The mounting plate 11 and the mounting shell 12 are spaced apart and fixedly connected along a third direction (e.g., direction e3 in the drawings).

[0081] For example, the third direction may be an up-down direction.

[0082] The locking tongue assembly 20 is mounted on the mounting bracket 10 and includes a movable locking tongue 21 for engaging with a locking ring on the vehicle body. For example, the locking tongue 21 is rotatable and includes a locking tongue body 210 and an engaging protrusion 213 disposed on the outer peripheral wall of the locking tongue body 210. The engaging push arm 32 of the engaging assembly 30 engages with or separates from the engaging protrusion 213 in the rotational direction of the locking tongue 21.

[0083] The suction assembly 30 is mounted on the mounting bracket 10 and includes a suction mechanism 31. The suction mechanism 31 includes a suction push arm 32 that selectively separates from or abuts the lock tongue 21. The suction push arm 32 contacts and moves along the guide surface 131. In the related art, a chute structure is used to guide the suction mechanism 31. Because the chute structure rigidly limits both sides of the suction mechanism, if the chute structure is deformed or foreign matter is present, the suction mechanism is easily stuck, resulting in suction failure. By providing a guide surface 131 on the mounting bracket 10, and making the suction push arm 32 contact the guide surface 131 and move along the guide surface 131, the guide surface 131 can guide the suction push arm 32 to move along the set path. Compared with the method of using a slide groove guide, the guide surface 131 rigidly limits one side of the suction structure, so that the suction push arm 32 can be stably sucked and reset along the set path, reducing the probability of inadequate suction, such as reducing or avoiding the probability of inadequate suction caused by the suction push arm 32 getting stuck; and, it can avoid providing a slide groove on the mounting bracket 10 to reduce the structural strength of the mounting bracket 10, so that the stability of the mounting bracket 10 is higher.

[0084] When the vehicle door changes from the open state to the semi-locked state, the vehicle door needs to be sucked in, and the suction push arm 32 moves along the guide surface 131 until the suction push arm 32 abuts against the lock tongue 21, pushing the lock tongue 21 to move to reach the first locking position, thereby achieving the effect of automatic suction and closing the door; after the vehicle door enters the fully locked state, it is no longer necessary to suck in the vehicle door, and the suction push arm 32 is separated from the lock tongue 21, and the suction push arm 32 is reset along the guide surface 131 to prevent the suction push arm 32 from interfering with the movement of the lock tongue 21.

[0085] According to the vehicle door lock 100 of the embodiment of the present invention, by providing a guide surface 131 on the mounting bracket 10, and making the suction push arm 32 contact the guide surface 131 and move along the guide surface 131, the guide surface 131 can guide the suction push arm 32 to move along the set path. Compared with the method of using a slide groove guide, the suction push arm 32 can be stably attracted and reset along the set path, reducing the probability of inadequate suction, such as reducing or avoiding the probability of inadequate suction caused by the suction push arm 32 getting stuck; and, it can avoid providing a slide groove on the mounting bracket 10 to reduce the structural strength of the mounting bracket 10, so that the stability of the mounting bracket 10 is higher.

[0086] According to some embodiments of the present invention, referring to Figure 2 The projection of the guide surface 131 on the reference surface is a suction motion trajectory, at least a portion of the suction motion trajectory is a curve, and the reference surface is a plane perpendicular to the guide surface 131. By making at least a portion of the suction motion trajectory a curve, the suction push arm 32 can sufficiently and stably push the lock tongue 21 to move during the process of the suction push arm 32 moving along the guide surface 131, thereby preventing the suction push arm 32 from losing contact with the lock tongue 21 and causing the suction function of the vehicle door lock 100 to fail.

[0087] According to some embodiments of the present invention, referring to Figure 2 The suction motion trajectory has at least one center of curvature, and the center of curvature of the suction motion trajectory is located on the side of the suction motion trajectory close to the lock tongue 21. By locating the center of curvature of the suction motion trajectory on the side of the suction motion trajectory close to the lock tongue 21, the suction push arm 32 can be made to rotate around the rotation axis of the lock tongue 21 during the movement of the guide surface 131 at the position where the suction push arm 32 contacts the lock tongue 21. This ensures that the suction push arm 32 always contacts the lock tongue 21 during the process of pushing the lock tongue 21 to move. The suction push arm 32 can fully and stably push the lock tongue 21 to move, thereby preventing the suction push arm 32 and the lock tongue 21 from losing contact, thereby preventing the suction function of the vehicle door lock 100 from failing.

[0088] According to some embodiments of the present invention, in the extension direction of the suction motion trajectory, the suction motion trajectory includes a plurality of motion trajectory segments connected in sequence, and at least two of the trajectory segments have different centers of curvature. By making the suction motion trajectory include a plurality of motion trajectory segments connected in sequence, and making at least two of the trajectory segments have different centers of curvature, the suction push arm 32 can always be in contact with the lock tongue 21 during the process of pushing the lock tongue 21 to move, so that the suction push arm 32 can more fully and stably push the lock tongue 21 to move, and avoid the suction push arm 32 and the lock tongue 21 from losing contact, which would cause the suction function of the vehicle door lock 100 to fail.

[0089] According to some embodiments of the present invention, referring to Figure 3 , the guide surface 131 is located on a side of the suction push arm 32 adjacent to the lock tongue 21. By making the guide surface 131 located on a side of the suction push arm 32 adjacent to the lock tongue 21, the guide surface 131 can be made easier to prepare, and the structure of the guide surface 131 is better arranged.

[0090] According to some embodiments of the present invention, referring to Figure 3 and Figure 13 The suction push arm 32 includes a suction push arm plate 33 and a matching column 34. The matching column 34 is fixed to the suction push arm plate 33. The suction push arm plate 33 abuts or separates from the lock tongue 21. The matching column 34 contacts the guide surface 131 and moves along the guide surface 131. By making the matching column 34 contact and move along the guide surface 131, it is possible to avoid wear of the suction push arm plate 33 during the sliding process along the guide surface 131, which may cause a reduction in the precision of the suction push arm plate 33. The lock tongue 21 can be fully and accurately pushed to move during the suction process. In addition, it is also convenient to spatially arrange the guide surface 131 and the lock tongue 21. For example, the guide surface 131 and the lock tongue 21 are spaced apart in a third direction (for example, the direction e3 in the accompanying drawings). The matching column 34 extends along the third direction. In this way, the suction push arm plate 33 can abut and contact with the lock tongue 21, and the matching column 34 can cooperate and contact with the guide surface 131, avoiding interference between the lock tongue 21 and the guide surface 131 during movement.

[0091] According to some embodiments of the present invention, referring to Figure 3 , the guide surface 131 is located on a side of the matching column 34 adjacent to the lock tongue 21. By making the guide surface 131 located on a side of the matching column 34 adjacent to the lock tongue 21, the guide surface 131 can be made to play a guiding role better.

[0092] According to some embodiments of the present invention, referring to Figure 13The suction component 30 includes a suction elastic auxiliary member 39, which has an elastic force on the suction push arm 32 toward the guide surface 131. By making the suction elastic auxiliary member 39 have an elastic force on the suction push arm 32 toward the guide surface 131, the suction elastic auxiliary member 39 can push the suction push arm 32, so that the suction push arm 32 continues to keep in contact with the guide surface 131, ensuring that the suction push arm 32 moves along the path guided by the guide surface 131. In addition, the suction component 30 can be subject to the joint constraint of the elastic auxiliary member and the guide surface 131, with one side of the suction component 30 subject to elastic constraint and the other side subject to rigid constraint. Compared with the related art that uses a slide groove as a guide to have a rigid constraint on both sides of the suction component 30, it can more fully avoid the suction component 30 getting stuck in the suction path and causing suction failure.

[0093] According to some embodiments of the present invention, referring to Figure 13 The suction elastic auxiliary member 39 is also used to drive the suction push arm 32 to reset when the suction push arm 32 is separated from the lock tongue 21. By making the suction elastic auxiliary member 39 drive the suction push arm 32 to reset when the suction push arm 32 is separated from the lock tongue 21, the suction push arm 32 is kept in contact with the guide surface 131, ensuring that the suction push arm 32 moves along the path guided by the guide surface 131, making the reset process of the suction push arm 32 more stable and not prone to getting stuck; and also preventing the suction push arm 32 from interfering with the movement of the lock tongue 21.

[0094] According to some embodiments of the present invention, referring to Figure 5-Figure 7The suction mechanism 31 includes a suction rocker arm 35, the suction assembly 30 includes an actuator assembly 80, the suction rocker arm 35 is rotatably connected to the mounting bracket 10, the actuator assembly 80 is connected to the suction rocker arm 35 to drive the suction rocker arm 35 to rotate, the actuator assembly 80 is connected to the suction rocker arm 35 to drive the suction rocker arm 35 to rotate, the suction push arm 32 is movably connected to the suction rocker arm 35, one end of the suction elastic auxiliary part 39 is abutted or connected to the suction push arm 32, and the other end of the suction elastic auxiliary part 39 is abutted or connected to the mounting bracket 10 or the suction rocker arm 35. By making the suction rocker arm 35 rotatably connected to the mounting bracket 10, the suction mechanism 31 can be fixed on the mounting bracket 10, preventing the suction component 30 from moving and causing the suction effect to fail; by making the suction rocker arm 35 rotatably connected to the mounting bracket 10 and the suction push arm 32 rotatably connected to the suction rocker arm 35, the movement of the suction push arm 32 in the suction mechanism 31 can be made more flexible, and the suction mechanism 31 can more stably push the lock tongue 21 to move to the first locking position. By making one end of the suction elastic auxiliary member 39 abut or connect to the suction push arm 32, and the other end of the suction elastic auxiliary member 39 abut or connect to the mounting bracket 10 or the suction rocker arm 35, 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 elastic auxiliary member 39, preventing the suction component 30 from continuously pushing and abutting the lock tongue 21 and causing the lock tongue 21 to become stuck.

[0095] For example, refer to Figure 16 The actuator assembly 80 includes an actuator body 82, an actuator mounting plate 81, a buffer block 83, and a shock-absorbing pad 84. The actuator body 82 is mounted on the actuator mounting plate 81 via the buffer block 83. The buffer block 83 is a conical structure made of rubber. The buffer block 83 is mounted on the actuator mounting plate 81 via a first annular clamping structure at its lower portion, thereby providing a buffering and shock-absorbing function. The actuator mounting plate 81 is a special-shaped structural plate suitable for mounting and fixing the actuator assembly 80 on the vehicle door, which can more effectively reduce the impact of bumps and vibrations generated during the movement of the vehicle on the actuator assembly 80. The lower surface of the actuator mounting plate 81 is provided with mounting feet 85 for mounting the shock-absorbing pad 84, further providing a shock-absorbing function.

[0096] For example, refer to Figure 15 and Figure 16The actuator body 82 is the power source for realizing the suction function. The actuator body 82 includes a drive unit 821, a suction cable 822, an actuator buckle 823, a rubber sleeve 824 and a connector 825. Among them, the drive unit 821 has a built-in motor and provides the power required to realize the suction function. The suction cable 822 is a steel wire cable structure, which can realize power transmission. The connector 825 is Z-shaped, and the suction cable 822 and the connector 825 are assembled and connected by die-casting. The actuator buckle 823 is fixed on the suction cable 822, and the rubber sleeve 824 is respectively connected to the actuator buckle 823 and the connector 825 through the joints at both ends. An actuator hook 192 is provided on the mounting bracket 10, and the actuator buckle 823 is connected to the actuator hook 192. Actuator assembly 80 connects to suction assembly 30 using connector 825, which passes through the actuator mounting hole on suction assembly 30. This simple connection structure reduces installation difficulty; connector 825 also prevents actuator assembly 80 from falling off and causing functional failure. Furthermore, mounting plate 11 is designed with a first U-shaped mounting clip into which the actuator assembly 80's mounting clip snaps into place.

[0097] According to some embodiments of the present invention, referring to Figure 13 The suction assembly 30 includes a suction push arm shaft 38, which is fixed to the suction rocker arm 35. The suction push arm 32 is rotatably connected to the suction push arm shaft 38. The suction elastic auxiliary member 39 is a torsion spring and is sleeved on the outer circumference of the suction push arm shaft 38. The rotatable connection between the suction push arm 32 and the suction rocker arm 35 makes the movement of the suction push arm 32 in the suction mechanism 31 more flexible and enables the suction mechanism 31 to more stably push the lock tongue 21 to move to the first locking position. By making the suction elastic auxiliary part 39 a torsion spring and being sleeved on the outer peripheral side of the suction push arm shaft 38, 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 elastic auxiliary part 39, thereby preventing the suction component 30 from continuously pushing and abutting the lock tongue 21 and causing the lock tongue 21 to be stuck; and it can be more convenient to fix the suction elastic auxiliary part 39 to prevent the suction elastic auxiliary part 39 from falling off.

[0098] For example, the suction assembly includes a suction rocker arm shaft 36 , which is fixed to the mounting bracket 10 , and the suction rocker arm 35 is rotatably connected to the suction rocker arm shaft 36 .

[0099] According to some embodiments of the present invention, referring to Figure 8 and Figure 13, the other end of the suction elastic auxiliary member 39 abuts or is connected to the suction rocker arm rotating shaft 36. By making the other end of the suction elastic auxiliary member 39 abut or is connected to the suction rocker arm rotating shaft 36, it is convenient to install and fix the other end of the suction elastic auxiliary member 39.

[0100] According to some embodiments of the present invention, referring to Figure 8 and Figure 13 The 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 abuts or separates from the lock tongue 21. The matching post 34 contacts and moves along the guide surface 131. One end of the suction elastic auxiliary member 39 abuts or is connected to the matching post 34. By making the matching post 34 contact and move along the guide surface 131, it is possible to prevent the suction push arm plate 33 from wearing during the sliding process along the guide surface 131, thereby preventing the suction push arm plate 33 from being reduced in precision. This ensures that the suction push arm plate 33 has sufficient precision when abutting or separating from the lock tongue 21, and accurately pushes the lock tongue 21 to move during the suction process. Furthermore, the spatial arrangement of the guide surface 131 and the lock tongue 21 can be facilitated. For example, the guide surface 131 and the lock tongue 21 are spaced apart in the third direction, and the mating post 34 extends along the third direction. This allows the suction push arm plate 33 to abut against the lock tongue 21, and the mating post 34 to abut against the guide surface 131, thereby preventing the lock tongue 21 from interfering with the guide surface 131 during movement. By abutting or connecting one end of the suction elastic auxiliary member 39 with the mating post 34, the mating post 34 is subjected to the elastic force of the suction elastic auxiliary member 39, thereby driving the suction push arm plate 33 to move, facilitating the installation and fixation of the suction elastic auxiliary member 39.

[0101] According to some embodiments of the present invention, referring to Figure 3 and Figure 13 The suction assembly 30 includes a suction rocker arm shaft 36 and a suction rocker arm reset member 37. 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 used to drive the suction rocker arm 35 to reset to its initial position. The suction rocker arm reset member 37 is a torsion spring and is sleeved on the outer peripheral side of the suction rocker arm shaft 36. 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. The suction assembly 30 includes a suction rocker arm reset member 37, which 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 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, thereby preventing the suction assembly 30 from continuously pushing and abutting the lock tongue 21 and causing the lock tongue 21 to be stuck.

[0102] According to some embodiments of the present invention, referring to Figure 2 and Figure 3 One end of the suction rocker arm reset member 37 is clamped to the edge of the suction rocker arm 35 through a first clamping structure. For example, a first clamping structure is formed at one end of the suction rocker arm reset member 37, and the first clamping structure is a clamping groove. The suction rocker arm reset member 37 is clamped to the edge of the suction rocker arm 35 through the first clamping structure. By forming a first clamping structure at one end of the suction rocker arm reset member 37 and clamping the first clamping structure to the edge of the suction rocker arm 35 through the first clamping structure, the connection between the suction rocker arm reset member 37 and the edge of the suction rocker arm 35 can be made more complete, thereby preventing the suction rocker arm reset member 37 from falling off the suction rocker arm 35 and causing the reset effect to fail. For example, one end of the suction rocker arm reset member 37 is formed in a "U" shape, so that the first clamping structure can be formed at one end of the suction rocker arm reset member 37.

[0103] According to some embodiments of the present invention, referring to Figure 2-Figure 8 The other end of the pull-in rocker arm reset member 37 is engaged with the mounting bracket 10 via a second engaging structure. By engaging the other end of the pull-in rocker arm reset member 37 with the mounting bracket 10 via the second engaging structure, the connection between the pull-in rocker arm reset member 37 and the mounting bracket 10 can be more complete, preventing the pull-in rocker arm reset member 37 from falling off the mounting bracket 10 and causing the reset effect to fail.

[0104] According to some embodiments of the present invention, referring to Figure 2-Figure 8 The second engaging structure includes a latching hole 17 and a hook 371. The mounting bracket 10 is provided with the latching hole 17, and the other end of the suction rocker arm reset member 37 is formed with a hook 371. The hook 371 engages with the latching hole 17 and hooks onto a portion of the mounting bracket 10. By providing the mounting bracket 10 with the latching hole 17 and forming the hook 371 on the other end of the suction rocker arm reset member 37, and engaging the hook 371 with the latching hole 17 and hooking onto a portion of the mounting bracket 10, the connection between the suction rocker arm reset member 37 and the mounting bracket 10 can be more fully achieved, preventing the suction rocker arm reset member 37 from falling off the mounting bracket 10 and causing the reset effect to fail. For example, the other end of the suction rocker arm reset member 37 can be formed into a "double L-shape" with two consecutive bends, so that the hook 371 is formed on the other end of the suction rocker arm reset member 37.

[0105] According to some embodiments of the present invention, referring to Figure 5 and Figure 6The suction rocker arm 35 is rotatable between an initial position and a suction position. During the movement of the suction rocker arm 35 from the initial position to the suction position, the lock tongue 21 is pushed to the first locking position. For example, the actuator assembly 80 is used to drive the suction rocker arm 35 from the initial position to the suction position to push the lock tongue 21 to the first locking position. The vehicle door lock 100 includes a rocker arm limiting structure. When the suction rocker arm 35 is in the initial position, the rocker arm limiting structure is used to limit the suction rocker arm 35. For example, a rocker arm limiting member 121 is provided on the mounting bracket 10. When the suction rocker arm 35 is in the initial position, the rocker arm limiting member 121 cooperates with the suction rocker arm 35 to limit the suction rocker arm 35. By using the actuator assembly 80 to drive the suction rocker arm 35 from the initial position to the suction position, the suction rocker arm 35 can drive the suction push arm 32 to push the lock tongue 21 to the first locking position during the automatic suction process, thereby achieving the effect of automatic suction. By providing a rocker arm limiter 121 on the mounting bracket 10, and when the suction rocker arm 35 is in the initial position, the rocker arm limiter 121 cooperates with the suction rocker arm 35, so that the rocker arm limiter 121 can limit the movement of the suction rocker arm 35 in the direction from the suction position to the initial position, thereby avoiding excessive movement of the suction rocker arm 35 in the direction of the initial position and causing interference with other components.

[0106] For example, the mounting bracket 10 includes a mounting plate 11 and a mounting shell 12 , and the mounting plate 11 and the mounting shell 12 are arranged at intervals along the third direction.

[0107] During the movement of the pull-in rocker arm 35 from the initial position to the pull-in position, the pull-in rocker arm 35 is driven by the actuator assembly 80 and continues to move until the pull-in push arm 32 abuts against the lock tongue 21 and pushes the lock tongue 21 to the first locking position, at which point the pull-in rocker arm 35 reaches the pull-in position and stops moving. During the movement of the pull-in rocker arm 35 from the pull-in position to the initial position, the pull-in rocker arm 35 moves under the action of the pull-in rocker arm reset member 37 until the rocker arm stop member 121 engages with the pull-in rocker arm 35, at which point the pull-in rocker arm 35 reaches the initial position and stops moving.

[0108] According to some embodiments of the present invention, referring to Figure 5 and Figure 6The rocker arm limiting structure includes a rocker arm limiting member 121 and a matching portion 351. When the suction rocker arm 35 is in the initial position, one of the rocker arm limiting member 121 and the matching portion 351 is disposed on the mounting bracket, and the other of the rocker arm limiting member 121 and the matching portion 351 is disposed on the suction rocker arm 35. When the suction rocker arm 35 is in the initial position, by disposing one of the rocker arm limiting member 121 and the matching portion 351 on the mounting bracket and the other of the rocker arm limiting member 121 and the matching portion 351 on the suction rocker arm 35, the rocker arm limiting member 121 can more fully limit the suction rocker arm 35, thereby preventing the suction rocker arm 35 from moving in the initial position and interfering with other components. In addition, the suction rocker arm 35 can be prevented from over-resetting.

[0109] According to some embodiments of the present invention, referring to Figure 2 and Figure 3 The mounting bracket 10 includes a first stopper 18 and a second stopper 19. These are located on opposite sides of the suction mechanism 31 in the width direction of the guide surface 131 to limit the position of the suction mechanism 31. By locating the positioning boss and the second stopper 19 on opposite sides of the suction mechanism 31 to limit the position of the suction mechanism 31, the mounting bracket 10 can more effectively limit the suction mechanism, thereby improving the precision of the suction mechanism. For example, the first stopper 18 is located on opposite sides of the rotation axis of the suction rocker arm 35.

[0110] For example, the mounting bracket 10 includes a mounting plate 11 and a mounting shell 12 arranged at intervals along the third direction, a first limiting portion 18 is provided on the mounting plate 11, and a second limiting portion 19 is provided on the mounting shell 12. The first limiting portion 18 and the second limiting portion 19 are located on opposite sides of the suction mechanism 31 along the third direction to limit the suction mechanism 31.

[0111] According to some embodiments of the present invention, the second limiting portion 19 is a limiting plate provided with reinforcing ribs 191. By providing the second limiting portion 19 with reinforcing ribs 191, the structural strength of the second limiting portion 19 can be improved and deformation of the second limiting portion 19 can be reduced.

[0112] According to some embodiments of the present invention, referring to Figure 10-12 The vehicle door lock 100 further includes a connector 90, which is mounted on the mounting bracket 10 and is provided with a first locking position sensor 91. The first locking position sensor 91 is used to detect whether the lock tongue 21 is in the first locking position. By making the vehicle door lock 100 further include a connector 90, which is mounted on the mounting bracket 10 and is provided with the first locking position sensor 91, the first locking position sensor 91 can detect whether the lock tongue 21 is in the first locking position, thereby achieving automatic monitoring.

[0113] For example, when the lock tongue 21 is in the first locking position, the first locking position sensor 91 detects that the lock tongue 21 is in the first locking position and transmits a signal to the vehicle sensor. The vehicle sensor controls the movement of the actuator assembly 80, and the actuator assembly 80 drives the suction assembly 30 to move so that the suction push arm 32 is separated from the lock tongue 21, thereby preventing the suction push arm 32 from interfering with the movement of the lock tongue 21 during the subsequent opening of the car door.

[0114] For example, the connector 90 includes an interface 96 , and the connector 90 is connected to the vehicle master controller via the interface 96 so as to transmit the signal received by the connector 90 to the vehicle master controller.

[0115] According to some embodiments of the present invention, referring to Figure 10-12 The lock tongue 21 includes a lock tongue body 210 and a first detection structure 211 provided on the lock tongue body 210. When the lock tongue 21 is in the first locking position, the positional relationship between the first detection structure 211 and the first locking position sensor 91 changes, thereby triggering the first locking position sensor 91 to generate a first locking position signal. For example, when the lock tongue 21 is in the first locking position, the first detection structure 211 and the first locking position sensor 91 change from contact to separation, thereby triggering the first locking position sensor 91. By including the first detection structure 211 in the lock tongue 21, when the lock tongue 21 rotates to the first locking position, the first detection structure 211 and the first locking position sensor 91 change from contact to separation, thereby triggering the first locking position sensor 91, thereby achieving an automatic monitoring effect.

[0116] For example, the first detection structure 211 is located on one side of the lock tongue body 210 in the third direction and is distributed along the circumference of the lock tongue body 210 .

[0117] According to some embodiments of the present invention, the first detection structure 211 is a raised structure arranged on the lock tongue body 210, and there is a first position relationship and a second position relationship between the first detection structure 211 and the first locking position sensor 91; in the first position relationship, the first detection structure 211 is in contact with the first locking position sensor 91, and in the second position relationship, the first detection structure 211 is separated from the first locking position sensor 91.

[0118] For example, when the lock tongue 21 is in the first locking position, the first detection structure 211 and the first locking position sensor 91 change from contact to separation and trigger the first locking position sensor 91. The first locking position sensor 91 detects that the lock tongue 21 is in the first locking position and transmits the signal to the vehicle sensor. The vehicle sensor controls the movement of the actuator assembly 80. The actuator assembly 80 drives the suction assembly 30 to move so that the suction push arm 32 is separated from the lock tongue 21, thereby preventing the suction push arm 32 from interfering with the movement of the lock tongue 21 during the subsequent opening of the car door.

[0119] For example, the first lock position sensor 91 is a micro switch.

[0120] According to some embodiments of the present invention, referring to Figures 4-10 The lock tongue 21 has a release position, a second locking position, and a first locking position. When the door is closed, the lock ring contacts the lock tongue 21. The lock tongue 21 moves with the vehicle door and squeezes the lock ring. The lock ring exerts a reaction force on the lock tongue 21, thereby driving the lock tongue 21 to move 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. The mounting bracket 10 is provided with a second locking position sensor 92. The second locking position sensor 92 is used to detect whether the lock tongue 21 is in the second locking position. By providing the second locking position sensor 92 on the mounting bracket 10, when the vehicle door is closed and the lock tongue 21 is in the second locking position, the second locking position sensor 92 detects that the lock tongue 21 is in the second locking position, facilitating the subsequent driving of the suction assembly 30 to automatically drive the lock tongue 21 from the second locking position to the first locking position, closing the vehicle door, avoiding the door being easily damaged due to the need to force the door to close, and improving comfort.

[0121] When the lock tongue 21 is in the second locking position, the second detection structure 75 of the locking arm 71 contacts and triggers the second locking position sensor 92, and the actuator assembly 80 drives the suction rocker arm 35 to rotate, and the suction rocker arm 35 drives the suction push arm 32 to move along the path guided by the guide surface 131, 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.

[0122] When the lock tongue 21 is in the first locking position, the first detection structure 211 and the first locking position sensor 91 change from contact to separation and trigger the first locking position sensor 91. The actuator assembly 80 drives the suction rocker arm 35 to rotate in the opposite direction, and the suction push arm 32 separates from the lock tongue 21.

[0123] According to some embodiments of the present invention, referring to Figure 10-12 The second locking position sensor 92 is connected to a signal line 93, with at least a portion of the signal line 93 routed along the edge of the mounting bracket 10. Routing at least a portion of the signal line 93 along the edge of the mounting bracket 10 prevents interference between the signal line 93 and other components. By providing the second locking position sensor 92 on the mounting bracket 10 and connecting it with the signal line 93, the placement of the second locking position sensor 92 can be more flexible, preventing interference between the second locking position sensor 92 and other components.

[0124] According to some embodiments of the present invention, referring to Figure 10-12 The mounting bracket 10 is provided with a first routing structure 111. The second locking position sensor 92 is connected to a signal line 93, and the signal line 93 is routed along the first routing structure 111 on the mounting bracket 10. By providing the first routing structure 111 on the mounting bracket 10 and routing the signal line 93 along the first routing structure 111 on the mounting bracket 10, the first routing structure 111 can limit the position of the signal line 93, prevent the signal line 93 from interfering with other components, and guide the signal line 93 to the position where it is connected.

[0125] For example, the first routing structure 111 includes a plurality of first routing buckles 112 arranged at intervals.

[0126] For example, a plurality of first routing buckles 112 are disposed along the edge of the mounting bracket 10 .

[0127] According to some embodiments of the present invention, referring to Figure 10-12 The vehicle door lock 100 also includes a connector 90 mounted on a mounting bracket 10. A second lock position sensor 92 is connected to a signal line 93, which is connected to the connector 90. By mounting the connector 90 on the mounting bracket 10, the position of the connector 90 is fixed, preventing movement and interference with other components. By connecting the second lock position sensor 92 to the signal line 93 and connecting the signal line 93 to the connector 90, the second lock position sensor 92 is electrically connected to the connector 90, transmitting the signal detected by the half-lock sensor to the connector 90.

[0128] In the related art, the second locking position sensor 92 is integrated into the connector 90, which may interfere with other components and impose significant placement limitations. By connecting the second locking position sensor 92 with a signal line 93, which is connected to the connector 90, the second locking position sensor 92 can be placed on other components, such as the mounting bracket 10, thereby alleviating placement limitations of the second locking position sensor 92.

[0129] According to some embodiments of the present invention, referring to Figure 10-12 The connector 90 is provided with a wiring seat 95, and the signal line 93 is connected to the wiring seat 95. By providing the wiring seat 95 on the connector 90 and connecting the signal line 93 to the wiring seat 95, the signal line 93 can be more easily connected and fixed.

[0130] According to some embodiments of the present invention, referring to Figure 10-12The connector 90 is provided with a second routing structure 94, and the signal line 93 is routed along the second routing structure 94 on the connector 90. By providing the second routing structure 94 on the connector 90, the signal line 93 is routed along the second routing structure 94 on the connector 90. The second routing structure 94 can guide the signal line 93 to the wiring base 95, facilitating the connection between the signal line 93 and the wiring base 95. In addition, the second routing structure 94 can limit the signal line 93 to prevent the signal line 93 from interfering with other components.

[0131] For example, the second routing structure 94 includes a plurality of second routing buckles 941 that are spaced apart.

[0132] For example, a plurality of second routing buckles 941 are arranged along the edge of the connector 90 .

[0133] According to some embodiments of the present invention, referring to Figures 4-10 The vehicle door lock 100 includes a locking arm assembly 70, which is mounted on the 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 including the locking arm 71 in the locking arm assembly 70, the locking arm 71 can limit the position of the lock tongue 21 when the lock tongue 21 is in the fully locked or second locked position, preventing the lock tongue 21 from slipping from the first locked position to the second locked position or from slipping from the second locked position to the released position, thereby preventing the vehicle door from opening abnormally and ensuring stable closing of the vehicle door.

[0134] According to some embodiments of the present invention, referring to Figure 10-12 The locking arm 71 includes a locking arm 71 body and a second detection structure 75 provided on the locking arm 71 body. When the lock tongue 21 is in the second locking position, the positional relationship between the second detection structure 75 and the second locking position sensor 92 changes, triggering the second locking position sensor 92. For example, when the lock tongue 21 is in the second locking position, the second detection structure 75 contacts the second locking position sensor 92 and triggers the second locking position sensor 92. By including the second detection structure 75 in the locking arm 71 and contacting the second locking position sensor 92 when the lock tongue 21 is in the second locking position, the second locking position sensor 92 can promptly detect that the lock tongue 21 is in the second locking position.

[0135] For example, the second lock position sensor 92 is a micro switch.

[0136] According to some embodiments of the present invention, the second detection structure 75 is a raised structure provided on the locking arm body 710. The second detection structure 75 and the second locking position sensor 92 have a third positional relationship and a fourth positional relationship. In the third positional relationship, the second detection structure 75 is in contact with the second locking position sensor 92, and in the fourth positional relationship, the second detection structure 75 is separated from the second locking position sensor 92. When the lock tongue 21 is in the second locking position, the second detection structure 75 and the second locking position sensor 92 change from contact to separation, triggering the second locking position sensor 92. The actuator assembly 80 drives the engaging rocker arm 35 to rotate, and the engaging push arm 32 pushes the lock tongue 21 to move.

[0137] According to some embodiments of the present invention, referring to Figures 4-10 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 releases the lock ring. In the second locked position, the lock ring cooperates with the lock tongue 21, and the second abutting surface 24 abuts the locking surface 72. In the first locked position, the lock ring cooperates with the lock tongue 21, and the first abutting surface 25 abuts the locking surface 72. By ensuring that the second abutting surface 24 abuts the locking surface 72 when the lock tongue 21 is in the second locked position, the locking arm 71 can more fully limit the lock tongue 21, preventing the lock tongue 21 from slipping from the second locked position to the released position, which could cause the vehicle door to open abnormally, and ensuring stable door closure. By ensuring that the first abutting surface 25 abuts the locking surface 72 when the lock tongue 21 is in the first locked position, the locking arm 71 can more fully limit the lock tongue 21, preventing the lock tongue 21 from slipping from the first locked position to the released position, which could cause the vehicle door to open abnormally, and ensuring stable door closure.

[0138] 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.

[0139] For example, the locking arm 71 body has a locking surface 72 .

[0140] According to some embodiments of the present invention, referring to Figures 4-10 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, thereby preventing 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.

[0141] According to some embodiments of the present invention, referring to Figures 4-10 The lock tongue 21 is rotatably connected to the mounting bracket 10. 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 making the lock tongue assembly 20 include the lock tongue reset member 23, the lock tongue reset member 23 is used to drive the lock tongue 21 to reset, so that 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.

[0142] When the vehicle door is in the process of moving from opening to closing, the lock tongue 21 is first 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.

[0143] When the lock tongue 21 is in the second locking position, the second detection structure 75 of the locking arm 71 contacts the second locking position sensor 92 and triggers the second locking position sensor 92, and 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 elastic auxiliary part 39 and makes the matching column 34 abut against the guide surface 131, 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.

[0144] The first detection structure 211 contacts and triggers the first locking position sensor 91, causing the actuator assembly 80 to drive the pull-in rocker arm 35 to rotate in the opposite direction. Under the action of the pull-in rocker arm reset member 37, the pull-in rocker arm 35 rotates counterclockwise around the pull-in rocker arm 35, driving the pull-in push arm 32 to move. Under the action of the pull-in elastic auxiliary member 39, the pull-in push arm 32 abuts against the guide surface 131 and resets along the guide surface 131, separating the pull-in push arm 32 from the lock tongue 21. The pull-in rocker arm 35 continues to rotate until the rocker arm limit member 121 is accommodated in the mating portion 351 of the pull-in rocker arm 35, at which point the pull-in rocker arm 35 stops rotating.
