[0044] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0045] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0046] The terms "comprises", "includes" or any other variants thereof in the specification and claims of this application are intended to cover non-exclusive inclusion, so that a process, method, article or terminal device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or terminal device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or terminal device including the element.

[0047] The following describes in detail a vehicle lock mechanism, a vehicle door lock, a vehicle door and a vehicle provided by the present application by listing specific embodiments.

[0048] Reference Figures 1 to 4 An embodiment of the present application provides a vehicle lock mechanism, including a first driving member, a transmission mechanism and a suction mechanism; the transmission mechanism is connected to the first driving member, and the transmission mechanism is suitable for interrupting the suction action of the suction mechanism under the drive of the first driving member.

[0049] Specifically, the first driving member, the transmission mechanism and the suction mechanism are all installed in the shell 5. The shell 5 is the shell of the door lock, which can be made of metal, alloy, hard plastic, composite material, etc., and has good strength and rigidity, and has certain processability. The shell 5 supports and protects the first driving member, transmission mechanism and suction mechanism inside it. The shell 5 can be provided with multiple partitions, reinforcing ribs, etc. to divide the inside of the shell 5 into multiple cavities, which is more convenient for pre-positioning and installation of the first driving member, transmission mechanism and suction mechanism. Specifically, the structural shape of the shell 5 needs to be compatible with the layout position of the first driving member, transmission mechanism and suction mechanism inside it, and this embodiment does not limit this.

[0050] Figure 1 is a front view of a door lock in a semi-locked state in an embodiment of the present application, Figure 2 is a rear view of a door lock in a semi-locked state according to an embodiment of the present application, referring to Figure 1and Figure 2 As shown, when the passenger lightly closes the door, the door lock is usually in a semi-locked state. In the semi-locked state, part of the lock tongue 4 is accommodated at the edge of the tongue groove, and is not completely accommodated in the tongue groove. In this state, the lock tongue 4 is easily forcibly attracted by the attraction mechanism, causing the door lock to become fully locked. Figure 3 is a front view of a vehicle door lock in a fully locked state according to an embodiment of the present application, Figure 4 is a rear view of a door lock in a fully locked state according to an embodiment of the present application, referring to Figure 3 and Figure 4 As shown, in the fully locked state, the lock tongue 4 extends into the tongue groove, and the entire or nearly entire lock tongue 4 is completely contained in the tongue groove. In this state, the door cannot be opened quickly. If a passenger forgets to bring items and wants to open the door temporarily, he needs to unlock the door lock again, which causes temporary inconvenience to the passenger when trying to open the door, affecting the passenger's riding experience.

[0051] The vehicle lock mechanism provided in the embodiment of the present application includes a first driving member and a transmission mechanism, and the transmission mechanism is connected to the first driving member. The first driving member can be an additional component provided in the vehicle door lock, and is mainly used to provide driving force for the transmission mechanism so that the transmission mechanism can perform an interruption action. The first driving member is electrically connected to the control system of the vehicle, and the first driving member can be controlled by the control system to perform an action. Exemplarily, if a passenger forgets to bring an item and wants to temporarily open the door, a door opening action is generated on the door. The door opening action can be triggered by the passenger pulling the door handle, pushing the door handle or touching the door handle, or can be triggered by the passenger inputting a voice command, a gesture command, etc. The control system triggers the first driving member to perform an action according to the door opening action, so that the transmission mechanism interrupts the suction action of the suction mechanism, that is, interrupts the process in which the lock tongue 4 of the door lock is forcibly sucked by the suction mechanism, so as to facilitate the passenger to easily open the door.

[0052] Optionally, in some embodiments of the present application, the first driving member includes a driving arm, which is connected to a transmission mechanism; the driving arm can swing and push the transmission mechanism to move during the swinging process, and the transmission mechanism is suitable for pushing the suction mechanism during the movement to interrupt the suction action. The driving arm can be a slat-like structure, and the first driving member includes a power mechanism in addition to the driving arm. In some embodiments, the power mechanism can be a motor, and in other embodiments, the power mechanism can be a control system of the vehicle. The driving arm is connected to the power mechanism, and the power mechanism provides power to the driving arm to make the driving arm swing. The driving arm can push the transmission mechanism to move during the swinging process, and the transmission mechanism pushes the suction mechanism during the movement, hindering the normal suction action, thereby interrupting the suction action.

[0053] Further, in some embodiments of the present application, the driving arm can reuse the unlocking arm 11 in the door lock, which is part of the unlocking mechanism in the door lock. The unlocking mechanism is mainly used to drive the lock tongue 4 out of the tongue groove, thereby unlocking the door lock. Figure 5 and Figure 6 As shown, the unlocking mechanism also includes an electric opening rocker arm 12 and a locking arm 13. The electric opening rocker arm 12 is connected to the door handle through some structures on the door lock (not shown in the figure). The passenger's door opening action can trigger the electric opening rocker arm 12 to move. At the same time, the electric opening rocker arm 12 is also electrically connected to the vehicle's control system. After receiving the passenger's door opening action, the control system generates an electrical signal, which triggers the electric opening rocker arm 12 to move. The electric opening rocker arm 12 and the unlocking arm 11 are in two perpendicular planes and are connected to each other. The other end of the unlocking arm 11 is connected to the locking arm 13. The end of the unlocking arm 11 extends to form a first limit plate 111 with a bending structure, and the end of the locking arm 13 extends to form a second limit plate 131 with a bending structure. The first limit plate 111 and the second limit plate 131 abut against each other, so that when the unlocking arm 11 moves, it can drive the locking arm 13 to move synchronously. Specifically, refer to Figure 6 As shown, when the electric opening rocker arm 12 rotates clockwise, it drives the unlocking arm 11 to swing counterclockwise, and the unlocking arm 11 drives the locking arm 13 to swing counterclockwise through the first limiting plate 111, so that the locking arm 13 moves away from the lock tongue 4 and breaks away from the obstruction to the lock tongue 4, thereby making the lock tongue 4 break away from the tongue groove, thereby unlocking the vehicle door lock.

[0054] In this embodiment, the driving arm reuses the unlocking arm 11. When the passenger performs the unlocking action and causes the unlocking arm 11 to swing, it can push the transmission mechanism to move. During the movement, the transmission mechanism pushes the suction mechanism to interrupt the suction action.

[0055] Optionally, refer to Figure 5 and Figure 6 In some embodiments of the present application, the transmission mechanism includes a connecting rod 21 and a first rocker arm 22; one end of the connecting rod 21 is fixedly connected to the driving arm, and the other end of the connecting rod 21 is fixedly connected to the first rocker arm 22; the connecting rod 21 is suitable for following the movement of the driving arm, and pushing the first rocker arm 22 to rotate during the movement, and the first rocker arm 22 pushes the suction mechanism to interrupt the suction action.

[0056] Specifically, refer to Figure 6 As shown, the transmission mechanism includes a connecting rod 21 and a first rocker arm 22. One end of the connecting rod 21 is fixedly connected to the driving arm, and the other end of the connecting rod 21 is fixedly connected to the first rocker arm 22. This embodiment is exemplified by taking the driving arm as the unlocking arm 11. Figure 7 and Figure 8As shown, the end of the connecting rod 21 close to the unlocking arm 11 is provided with a first connecting hole 211a, and the first connecting hole 211a is used to pass the first connecting member 211 to achieve a fixed connection between the connecting rod 21 and the unlocking arm 11. The first connecting member 211 can be any type of rivet, bolt, screw, pin, etc., as long as it can ensure a reliable connection between the connecting rod 21 and the unlocking arm 11. Correspondingly, the end of the connecting rod 21 close to the first rocker arm 22 is provided with a second connecting hole, and the second connecting hole is used to pass the fastener to achieve a fixed connection between the connecting rod 21 and the first rocker arm 22. Fixing member 212 Fixing member 212 refers to Figure 6 As shown, during the unlocking action performed by the driving member, the unlocking arm 11 rotates counterclockwise, the unlocking arm 11 drives the connecting rod 21 to move to the left, the connecting rod 21 pushes the first rocker arm 22 to rotate clockwise, and the first rocker arm 22 pushes the suction mechanism during the clockwise rotation to interrupt the suction action.

[0057] Therefore, the vehicle lock mechanism in this embodiment can interrupt the pull-in action through the setting of the connecting rod 21 and the first rocker arm 22, reducing the delay of mechanical movement. At the moment of pull-in, the unlocking arm 11 can respond immediately, improving the execution speed of the unlocking action, so that the passenger can hardly feel the pause in the unlocking process. At the same time, this design avoids complex multi-stage transmission and reduces the complexity of the interruption structure, thereby helping to reduce the risk of failure of the vehicle lock mechanism and improve working reliability.

[0058] Optionally, refer to Figure 6 In some embodiments of the present application, the transmission mechanism also includes a fixing member 212 and a torsion spring 25; the fixing member 212 is arranged at one end of the connecting rod 21 close to the first rocker arm 22, and part of the torsion spring 25 is wound around the fixing member 212, and the two ends of the torsion spring 25 are respectively fixedly connected to the first rocker arm 22; the first rocker arm 22 pushes the suction mechanism through the torsion spring 25.

[0059] Specifically, refer to Figure 7 As shown, a through hole 212a is provided at one end of the connecting rod 21 close to the first rocker arm 22, and the through hole 212a is used to pass the fixing member 212 to fix the fixing member 212 on the connecting rod 21. The torsion spring 25 is a cylindrical coil spring that bears torque, which will undergo elastic deformation under the action of load and can return to its original state when the load disappears. The torsion spring 25 is wound around the fixing member 212, and the two ends of the torsion spring 25 extend along the extension direction of the first rocker arm 22 and are fixedly connected to the first rocker arm 22. The connection between the torsion spring 25 and the first rocker arm 22 can be achieved by various methods such as limited clamping, adhesive connection, etc., which are not limited in this embodiment.

[0060] In this embodiment, the first rocker arm 22 drives the suction mechanism to move through the torsion spring 25. The length and winding method of the torsion spring 25 can be set according to the position of the suction mechanism, and its adjustment method is more flexible. In this way, the first rocker arm 22 drives the suction mechanism to be converted into the torsion spring 25 driving the suction mechanism. Since the first rocker arm 22 and the suction mechanism are usually rigid components, this is equivalent to converting the contact between the two rigid components into the contact between an elastic component and a rigid component, which helps to reduce the design requirements and difficulty of the first rocker arm 22. In addition, the torsion spring 25 can also absorb the error in the driving process of the first rocker arm 22 to a certain extent, which helps to contact the suction mechanism smoothly. At the same time, the torsion spring 25 can play a certain buffering role when contacting the suction mechanism, which helps to reduce the probability of damage to the suction mechanism, thereby playing a certain protective role for the suction mechanism.

[0061] Reference Figure 6 and Figure 8 As shown, in some embodiments of the present application, two clamping portions 221 are provided on the first rocker arm 22, and the two clamping portions 221 are arranged at intervals along the extension direction of the first rocker arm 22. One end of the torsion spring 25 is clamped in one clamping portion 221, and the other end of the torsion spring 25 bypasses the fixing member 212 and is clamped in the other clamping portion 221, thereby making the fixing method of the torsion spring 25 simple and reliable.

[0062] Optionally, refer to Figure 4 In some embodiments of the present application, a relief portion 222 is provided on the side of the first rocker arm 22 facing away from the connecting rod 21, and a partial positive projection of the torsion spring 25 on the first rocker arm 22 is located in the relief portion 222, and the relief portion 222 is suitable for providing a relief space for the contact between the torsion spring 25 and the suction mechanism.

[0063] Specifically, the side of the first rocker arm 22 away from the connecting rod 21 can be reduced in size to form an avoidance portion 222. The positive projection of the torsion spring 25 on the first rocker arm 22 refers to the projection of the torsion spring 25 on the first rocker arm 22 in a direction perpendicular to the first rocker arm 22. Part of the positive projection of the torsion spring 25 is located in the avoidance portion 222, so that the avoidance portion 222 can provide an avoidance space when the torsion spring 25 contacts the suction mechanism, preventing the first rocker arm 22 from interfering with the suction mechanism or other components around the suction mechanism, thereby ensuring that the torsion spring 25 is in full contact with the suction mechanism, so that the torsion spring 25 can stably push the suction mechanism. Among them, the edge of the avoidance portion 222 can be set to an arc structure to adapt to the shape and structure of the suction mechanism to achieve a better avoidance effect.

[0064] Optionally, Figure 7 is a schematic diagram of a connecting rod 21 in an embodiment of the present application, referring to Figure 7In some embodiments of the present application, the connecting rod 21 is provided with a bending portion 210, which is bent along a side away from the lock tongue 4. The bending portion 210 is suitable for providing an avoidance space for the connecting rod 21 to avoid interference with the lock tongue 4 or other locking components during the movement of the connecting rod 21, thereby affecting its normal movement and hindering the interruption function.

[0065] Optionally, in some embodiments of the present application, the vehicle lock mechanism further includes a second driving member, and the second driving member is suitable for driving the lock tongue 4 to move when the lock tongue 4 cannot be separated from the locking position, so as to make the lock tongue 4 separate from the locking position. For example, if the vehicle is in a low temperature environment for a long time, the lock tongue 4 may be frozen with the sheet metal inside the vehicle. In this case, even if the locking arm 13 is separated from the obstruction to the lock tongue 4, the lock tongue 4 cannot smoothly separate from the locking position, wherein the locking position includes the position where the lock tongue 4 is completely accommodated in the tongue groove and is frozen with the sheet metal inside the vehicle and cannot be unlocked, and also includes the position where the lock tongue 4 is partially accommodated in the tongue groove and is frozen with the sheet metal inside the vehicle and cannot be unlocked, and also includes the position where the lock tongue 4 is not accommodated in the tongue groove but is frozen with the sheet metal inside the vehicle and cannot be unlocked, so that the lock tongue 4 cannot smoothly separate from the locking position, which means that the door lock cannot be unlocked. At this time, the second driving member can drive the lock tongue 4 to move, so that the lock tongue 4 can smoothly separate from the locking position, thereby unlocking the door lock. Therefore, in this embodiment, by providing the second driving member, the vehicle lock mechanism can have the ice-breaking function of the vehicle door lock in addition to the interruption and attraction function.

[0066] Optionally, refer to Figure 5 and Figure 6 In some embodiments of the present application, the second driving member includes a second rocker arm 23, which is hinged to the first rocker arm 22; the second rocker arm 23 is suitable for contacting the suction mechanism during the process of the first rocker arm 22 pushing the suction mechanism. Specifically, the second rocker arm 23 is hinged to the first rocker arm 22, and the first rocker arm 22 can rotate relative to the second rocker arm 23. In combination with the above embodiments, refer to Figure 6 As shown, when the first rocker arm 22 rotates clockwise, the first rocker arm 22 can push the suction mechanism to contact the second rocker arm 23. Figure 5 1 is a front view of the contact between the suction mechanism and the second rocker arm 23 in one embodiment of the present application. Figure 6 It is a rear view of the suction mechanism in one embodiment of the present application in contact with the second rocker arm 23.

[0067] Optionally, in some embodiments of the present application, the suction mechanism includes an actuator 31, a third rocker arm 32 and a fourth rocker arm 33; one end of the third rocker arm 32 is fixedly connected to the actuator 31, and the other end of the third rocker arm 32 is hinged to the fourth rocker arm 33; the first rocker arm 22 is suitable for pushing the fourth rocker arm 33 to interrupt the suction action, and the second rocker arm 23 is suitable for contacting the fourth rocker arm 33 during the movement of the fourth rocker arm 33.

[0068] Specifically, the actuator 31 is electrically connected to the vehicle control system, and its movement is controlled by the mechanical logic preset by the vehicle. One end of the third rocker arm 32 is fixedly connected to the actuator 31, and the fixed connection can be achieved by fastener assembly connection, limit clamping, etc. The other end of the third rocker arm 32 is hinged to the fourth rocker arm 33, and the third rocker arm 32 and the fourth rocker arm 33 can rotate relative to each other. The actuator 31 can drive the third rocker arm 32 to move, and the third rocker arm 32 drives the fourth rocker arm 33 to move, so as to realize the suction action of the suction mechanism.

[0069] In addition, the suction mechanism also includes a first reset member 321 and a second reset member 331. One end of the first reset member 321 is connected to the housing 5, and the other end is connected to the third rocker arm 32. The first reset member 321 can perform a reset operation on the third rocker arm 32, so that after the force of the actuator 31 is removed, the third rocker arm 32 can return to its initial position. One end of the second reset member 331 is connected to the housing 5, and the other end is connected to the fourth rocker arm 33. The second reset member 331 can perform a reset operation on the fourth rocker arm 33, so that after the force of the actuator 31 is removed, the fourth rocker arm 33 can return to its initial position. Among them, the first reset member 321 and the second reset member 331 can be torsion springs, etc., with a simple structure, easy installation and layout, and reliable reset effect.

[0070] Optionally, in some embodiments of the present application, the suction mechanism includes a limiting column 330, the limiting column 330 is provided on the fourth rocker arm 33, and the second rocker arm 23 is suitable for contacting the limiting column 330. Figure 6 As shown, a limiting groove is provided on the second rocker arm 23, and the limiting groove is suitable for clamping the limiting column 330. When the first rocker arm 22 rotates clockwise, it will push the fourth rocker arm 33 to move, so that the limiting column 330 on the fourth rocker arm 33 is clamped in the limiting groove on the second rocker arm 23, thereby helping to effectively contact the second rocker arm 23 with the suction mechanism, and the limiting column 330 and the limiting groove are simple and easy to process, which helps to reduce the design difficulty of the vehicle lock mechanism.

[0071] In summary, the specific process of the suction mechanism performing the suction action in the embodiment of the present application is as follows: Figure 1 As shown, the locking arm 13 stops the lock tongue 4 in the half-locked position. At this time, the actuator 31 is driven to move rightward, driving the third rocker arm 32 to overcome the force of the first reset member 321 and rotate in the clockwise direction. The fourth rocker arm 33 is hinged to the third rocker arm 32, so that the fourth rocker arm 33 will move leftward accordingly. At the same time, the fourth rocker arm 33 rotates counterclockwise under the action of the second reset member 331 until it contacts the lock tongue 4, and overcomes the reaction force of the door seal to drive the lock tongue 4 to rotate counterclockwise to the full-locked position. The state of the lock tongue 4 in the full-locked position is shown in FIG. Figure 3 As shown, the door lock is switched from a half-locked state to a fully locked state, thereby locking the door.

[0072] The specific process of the transmission mechanism interrupting the pull-in action in the embodiment of the present application is as follows: Figure 6 As shown, the locking arm 13 stops the lock tongue 4 in the semi-locked position. If the passenger wants to open the door temporarily, the electric opening rocker arm 12 is triggered to rotate clockwise, and the electric opening rocker arm 12 drives the unlocking arm 11 to rotate counterclockwise. The unlocking arm 11 rotates counterclockwise to drive the connecting rod 21 to move left, and the connecting rod 21 drives the first rocker arm 22 to rotate clockwise. The torsion spring 25 rotates clockwise relative to the fixing member 212, and the torsion spring 25 contacts the limit column 330 on the fourth rocker arm 33, pushing the limit column 330 to move, so that the suction action is interrupted. The door lock can be directly and quickly switched from the semi-locked state to the unlocked state to achieve the unlocking of the door.

[0073] Optionally, refer to Fig. 9 and Fig.10 In some embodiments of the present application, the second driving member further includes a crimping plate 26, which is fixedly connected to the second rocker arm 23; the crimping plate 26 acts on the lock tongue 4 to disengage the lock tongue 4 from the locked position.

[0074] Specifically, the door lock can be unlocked when the lock tongue 4 is out of the locked position. Fig. 9 is a rear view of a door lock in the embodiment of the present application before the ice breaking state, referring to Fig. 9 As shown, in cold weather, the electric opening rocker arm 12 is driven to rotate clockwise, and the electric opening rocker arm 12 drives the unlocking arm 11 to rotate counterclockwise, and the unlocking arm 11 drives the locking arm 13 to rotate counterclockwise, so that the locking arm 13 rotates to a position that is disengaged from the lock tongue 4. At this time, since the lock tongue 4 is frozen to the sheet metal inside the vehicle and cannot be released to unlock, it is necessary to execute the ice-breaking function to enable the lock tongue 4 to smoothly disengage from the locked position to achieve unlocking.

[0075] The specific process of the second driving member performing the ice-breaking action in the embodiment of the present application is as follows: Figure 6 As shown, the unlocking arm 11 rotates counterclockwise to drive the connecting rod 21 to move leftward, the connecting rod 21 drives the first rocker arm 22 to rotate clockwise, the torsion spring 25 rotates clockwise relative to the fixing member 212, the torsion spring 25 contacts the limit post 330 on the fourth rocker arm 33, pushes the limit post 330 to be stuck in the limit groove of the second rocker arm 23, and makes the fourth rocker arm 33 rotate counterclockwise to the ice-breaking state. It can be seen that the first part of the ice-breaking action is almost the same as the process of interrupting the pull-in action, and refer to Fig. 9As shown, at this time, the actuator 31 is driven to move leftward, driving the third rocker arm 32 to rotate counterclockwise, the third rocker arm 32 drives the fourth rocker arm 33 to rotate counterclockwise, and the fourth rocker arm 33 pushes the second rocker arm 23 to rotate clockwise. During the clockwise rotation of the second rocker arm 23, the pressing plate 26 is driven to contact the lock tongue 4. The second rocker arm 23 continues to rotate clockwise, so that the pressing plate 26 pushes the lock tongue 4, and then the lock tongue 4 overcomes the ice sealing force and rotates counterclockwise (unlocking direction), thereby realizing the ice breaking function. Fig.10 This is a rear view of a door lock in an ice-breaking state in an embodiment of the present application.

[0076] Optionally, refer to Figure 5 In some embodiments of the present application, the second driving member further includes a reset member 27, which is connected to the second rocker arm 23 or the crimping plate 26, and is suitable for pulling the second rocker arm 23 and the crimping plate 26 to reset. Specifically, when the force of the actuator 31 is removed, the driving force of the fourth rocker arm 33 on the second rocker arm 23 disappears, and the reset member 27 can pull the second rocker arm 23 and the crimping plate 26 back to their initial positions. The reset member 27 can be a torsion spring. Figure 5 In the shown manner, the second rocker arm 23 and the crimping plate 26 are fixedly connected together by fasteners such as rivets and pins, and the reset member 27 is sleeved on the fastener. One end of the reset member 27 is fixedly connected to the fastener, and the other end is fixedly connected to the second rocker arm 23 or the crimping plate 26. Since the second rocker arm 23 and the crimping plate 26 are in a fixedly connected state, the movement of the reset member 27 can realize the reset of the second rocker arm 23 and the crimping plate 26 at the same time.

[0077] Optionally, refer to Fig. 9 and Fig.10 In some embodiments of the present application, the crimping plate 26 and the second rocker arm 23 can be processed into an integral part through an integrated molding process to ensure the connection reliability between the crimping plate 26 and the second rocker arm 23, which also helps to simplify the structure of the transmission mechanism and reduce the difficulty of processing. Alternatively, the crimping plate 26 is a bent plate, which has a certain deformation ability and can reduce the contact rigidity between the crimping plate 26 and the lock tongue 4 to a certain extent, avoiding damage to the surface of the lock tongue 4. Of course, the bent plate and the second rocker arm 23 can also be processed into an integral part to further enhance the advantages of the transmission mechanism.

[0078] Optionally, refer to Fig. 9 and Fig.10In some embodiments of the present application, a crimping column 41 is provided on the lock tongue 4, and the crimping plate 26 acts on the outer peripheral surface of the crimping column 41 to disengage the lock tongue 4 from the locked position. Among them, the outer peripheral surface of the crimping column 41 refers to the surface arranged axially around the crimping column 41. The crimping column 41 can be cylindrical, square column or other prismatic structures. The crimping column 41 can be a rivet, a pin or other structure on the lock tongue 4. The specific type is not limited in this embodiment. In this embodiment, the contact between the crimping plate 26 and the crimping column 41 is used to break the ice of the lock tongue 4. The crimping plate 26 and the lock tongue 4 can be allowed to be in different planes, and the crimping plate 26 can be prevented from causing damage to the surface of the lock tongue 4, which helps to reduce the design difficulty of the crimping plate 26.

[0079] Optionally, in some embodiments of the present application, the crimping plate 26 is provided with an arc-shaped groove, which is suitable for accommodating part of the crimping column 41, wherein the shape and size of the arc-shaped groove are adapted to the shape and size of the crimping column 41, so that part of the crimping column 41 can be embedded in the arc-shaped groove, which helps to prevent the crimping column 41 from detaching from the crimping plate 26 during the crimping process, thereby improving the reliability of the crimping effect.

[0080] The embodiment of the present application also provides a vehicle door lock, which adopts an electric door lock. The locking or unlocking of the electric door lock can be controlled by the vehicle's control system. The vehicle door lock includes a vehicle lock mechanism as in any of the aforementioned embodiments. If a passenger forgets to bring an item and wants to temporarily open the door, the first driving member in the vehicle lock mechanism can drive the transmission mechanism to move, so that the transmission mechanism interrupts the suction action of the suction mechanism, so that the passenger can easily pull the door to open the door, effectively improving the smoothness, convenience and timeliness of unlocking the door lock.

[0081] An embodiment of the present application also provides a vehicle door, which includes a door lock as described in the aforementioned embodiment. The door lock is unlocked smoothly, which helps to improve the smoothness and convenience of passengers when opening the door, so that passengers can intuitively feel the timeliness of the door lock response, thereby improving the passenger's riding experience.
