Description

Technical Field

[0001] The present disclosure relates to the technical field of vehicle doors, and in particular to a lock assembly mechanism, a vehicle door and a vehicle. Background Art

[0002] In addition to using traditional manual handles to open the doors of motor vehicles, they can also be equipped with an electronic control operating system independent of the manual operation structure, so that the doors can be opened freely by the manual handle and the electronic control system respectively. However, it is necessary to ensure that the door can still be opened by the handle when the electronic control system structure is damaged or the door lock motor fails.

[0003] In actual use, when the electric control component fails after the door is opened, the electric opening arm loses the reset power and remains in the current fault position. At this time, the electric opening arm will interfere with the movement of the unlocking clutch connection (door insurance) used to control the door lock switch between the unlocking position and the locking position. The operation of closing the door also requires the intervention of the internal door lock structure. Specifically, before the door is closed, the lock must be returned to the locked state so that the door lock can be locked and the door can be closed normally.

[0004] In the related art, after the vehicle door is opened and the electric opening arm is stuck, the movement of the locking member from the locked position to the unlocked position will be interfered by the electric opening arm, so that the locking member abuts against the electric opening arm and cannot reach the unlocked position. When a manual handle is used to control the vehicle door lock to open, the locking member abuts against the electric opening arm and rotates along the electric opening arm. When it turns to the side of the electric opening arm, the toggle plate pulls the locking member to reach the maximum unlocked position and is stuck to the side of the electric opening arm. At this time, the front and rear door lock opening plates cannot be reset to the initial position, resulting in the vehicle door being unable to close normally. Therefore, it is necessary to perform the locking stroke of the locking device as described above each time before closing the vehicle door. The operation is complicated and cumbersome, and it is relatively inconvenient to use. There is still a safety hazard that the vehicle door cannot be effectively closed after the vehicle starts.

DETAILED DESCRIPTION

[0036] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0037] The terms "first", "second", etc. used in the present disclosure are to distinguish one element from another element, and do not have order or importance. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0038] Before describing the structure of the embodiment of the present disclosure, it should be first explained that, for the convenience of description, the embodiment of the present disclosure defines the door lock as a primary lock and a secondary lock, wherein the primary lock controls the opening or closing action of the door, including the electric drive component and the manual drive component in the first drive member described below, which can independently control the primary lock respectively to realize two switch lock modes of electric control and manual control; the secondary lock can control the safety state of the door lock, and can control the locking component to move between the locked position and the unlocked position through the locking unit to open or close the safety state of the door lock. In the locked position, the locking component locks the door. At this time, the primary lock cannot be opened without first opening the locking unit. The locking unit and the locking component are both commonly used components in the field, and the present disclosure does not limit their specific structures.

[0039] The present disclosure provides a lock assembly mechanism, such as Figure 2 and Figure 3 As shown, the lock assembly mechanism includes a lock seat 10, a locking member 20 and a first driving member.

[0040] The lock seat 10 can move in a preset direction to open the primary lock of the door or allow the primary lock of the door to be closed. The preset direction can be a direction of rotational movement or a direction of linear movement. The following only takes rotational movement as an example for illustrative description. Figure 2In the embodiment, the lock seat 10 rotates counterclockwise around the operating axis L1 to open the primary lock, and rotates clockwise to allow the primary lock to be closed. In this case, the "preset direction" refers to the direction of the circumferential movement of the lock seat 10 when it rotates. For details, please refer to Figure 2 The linkage between the lock seat 10 and the primary lock of the vehicle can adopt the common forms in the art, and no specific restrictions are made here. For example, the primary lock can be a latch-type lock, and a multi-link assembly can be designed between the lock seat 10 and the lock.

[0041] The locking member 20 is movably connected to the lock base 10. Figure 2 The locking member 20 has an unlocking position P1 and a locking position P2, wherein the locking member 20 is in the unlocking position P1 when it is relatively far from the operating axis L1, and is in the locking position P2 when it is close to the operating axis L1. The relevant structure and principle of the locking member 20 locking the vehicle are not described here, and it can be a component of the locking unit 50 commonly used in the art.

[0042] The first driving member may include an electric driving member 30 and a manual driving member, which can respectively drive the locking member 20 located at the unlocking position P1 to move along a preset direction to drive the lock seat 10 to rotate and release the primary lock of the vehicle door.

[0043] Among them, the electric drive component 30 may include a main body and a protrusion 31 connected to the main body. The electric drive component 30 can move along a preset direction under the drive of the power component 60. The main body may be provided with an air avoidance area 301, and the air avoidance area 301 can be configured so that when the output of the power component 60 used to drive the electric drive component 30 fails, the locking component 20 can fall into the air avoidance area 301 and be upper-limited in the preset direction by the protrusion 31. The air avoidance area 301 can be designed so that the locking component 20 reaches the unlocking position P1 after falling into it. At the same time, the manual drive component can drive the locking component 20 to move in the preset direction and drive the lock seat 10 to move to release the vehicle door.

[0044] Through the above technical solution, the main body of the electric drive 30 is provided with an air-avoiding area 301. When the output of the power component 60 fails, the electric drive 30 is stuck in the current rotation position where the door can be opened and cannot be rotated. The lock 20 used to push the lock seat 10 to move can fall into the air-avoiding area 301 by switching the unlocking position once, so that the manual drive can replace the electric drive 30 to push the lock 20 in the air-avoiding area 301 along the preset direction, so that the movement of the lock seat 10 is not restricted and the door can be opened and closed freely. At the same time, the convex part 31 of the electric drive 30 can limit the maximum rotation displacement of the lock 20 in the preset direction to prevent the lock 20 from leaving the air-avoiding area 301 and being stuck on the side of the convex part 31, causing the lock seat 10 to be unable to be effectively reset, avoiding the need to switch the unlocking position of the lock 20 every time the door is opened and closed, thereby simplifying repetitive operations, being convenient to use, and effectively solving the safety hazard that the door cannot be effectively closed after the vehicle starts.

[0045] For ease of understanding, the detailed process of opening and closing the door will be described below. The power component 60 may include a motor and a transmission component (such as a cable) connected between the motor and the electric drive component 30. Figure 2 and Figure 3 As shown, in the current state, when the vehicle door is opened using the electric drive 30, the motor of the power component 60 can drive the pull wire to pull the electric drive 30 to rotate counterclockwise around the operating axis L1. When the electric drive 30 rotates counterclockwise, the convex part 31 abuts against the side of the locking member 20. When the motor continues to drive, the electric drive 30 continues to push the locking member 20. Under the action of the thrust, the locking member 20 drives the lock seat 10 to rotate counterclockwise around the operating axis L1 in a preset direction, and opens the first-level lock of the vehicle door after rotating to a certain angle, thereby realizing the opening of the vehicle door.

[0046] Similarly, after the vehicle door is opened, the motor can reverse and drive the electric drive component 30 to move in the opposite direction, or the motor loses control of the electric drive component 30, and the electric drive component 30 is driven by other structures of the power component 60 to move in the opposite direction, and the protrusion 31 and the locking component 20 are gradually separated and contacted and abutted. The locking component 20 loses the pushing force of the protrusion 31, and the lock seat 10 can be driven by the torsion spring structure or other structures provided on the operating shaft L1 to rotate clockwise in a preset direction to release the state in which the first-level lock of the vehicle door is continuously opened. At this time, the vehicle door can be closed freely.

[0047] When the power component 60 fails (e.g., the motor fails, the cable is stuck, etc.), the electric drive component 30 is stuck at the current rotation position of the door opening and cannot be rotated. Figure 2 , the locking member 20 at the unlocking position P1 is kept in contact with the protruding member 31 in the preset direction. At this time, since the clockwise rotation (i.e., movement toward the locking direction) of the lock seat 10 is blocked by the stationary electric drive member 30 (specifically the protruding member 31), the primary lock of the door is always kept in the open state, and the door cannot be closed normally. In order to close the door normally, the locking member 20 needs to be moved to the locking position P2 so that the abutment relationship between the lock seat 10 and the protruding member 31 in the preset direction is released. In this way, the lock seat 10 can rotate clockwise in the preset direction, the primary lock is released from the continuously open state, and the door can be closed normally. Then, the door opening and closing action is switched from the electronic control system to manual operation, and the door can be opened normally by the manual drive member.

[0048] refer to Figure 5 The position state between the electric drive member 30 and the locking member 20 is shown when the power member 60 fails. However, it should be noted that Figure 5There is a locking member 20 in both the unlocking position P1 and the locking position P2, which is to indicate the two states of the locking member 20, rather than the presence of two locking members 20 in this structure. As described above, after the power component 60 fails, the electric drive member 30 basically remains in the position where the failure occurs. By moving the locking member 20 to the locking position P2, the lock seat 10 can be reset, allowing the door to be closed. At this time, when the locking member 20 is moved to the unlocking position P1 again, the locking member 20 can fall into the air avoidance area 301 of the electric drive member 30, and can be pushed by the manual drive member to move in the air avoidance area 301 in a preset direction, so that the door can be opened freely. After the door is opened, the locking member 20 is not subject to resistance in the air avoidance area 301, and the lock seat 10 can freely rotate and reset, so that the door can be opened and closed freely. At the same time, the side of the protrusion 31 located in the air-avoiding area 301 can limit the maximum rotation displacement of the locking member 20, prevent the locking member 20 from being separated from the air-avoiding area 301, and thus prevent the locking member 20 from being stuck on one side of the electric drive member 30 again, and there is no need to repeatedly switch the unlocking position of the locking member 20 during each opening and closing process of the door, thereby simplifying repetitive operations. In addition, when the position where the electric drive member 30 is stuck is close to the limit position of the primary lock opening, if the locking member 20 is blocked by the protrusion 31 and the lock seat 10 cannot be reset, it is easy to create an illusion that the door has been closed when closing the door, and the vehicle is easy to open automatically after it starts running, which brings safety hazards to the driver and passengers. The protrusion 31 can effectively solve this problem by limiting the locking member 20 in the air-avoiding area 301, ensuring the effective closing of the door.

[0049] In order to better understand the above scheme, we will continue to combine Figure 1 Describe the relevant structures and their motion forms in the related technology. Figure 1The lock assembly mechanism includes an electric opening arm 1 and a driving component composed of a first toggle plate 2, a second toggle plate 3 and a torsion spring 4, wherein the electric opening arm 1 is equivalent to the electric driving component 30 of the embodiment of the present disclosure, and the first toggle plate 2, the second toggle plate 3 and the torsion spring 4 as a whole are equivalent to the locking unit 50 in the embodiment of the present disclosure (i.e., used to switch the unlocking position of the locking component 20). After the electric opening arm 1 rotates and the electric control fails, the same movement process described above will be faced (i.e., the locking member 20 first moves to the locking position P2, and then the lock seat 10 rotates clockwise), but the locking member 20 will stop on the stopper 5 of the electric opening arm 1 during the movement from the locking position P2 to the unlocking position P1. At this time, when the lock seat 10 is driven by the manual operating mechanism to perform the door opening operation, it rotates counterclockwise until the locking member 20 is separated from or nearly separated from the stopper 5. Since the first toggle plate 2 and the second toggle plate 3 are connected by the torsion spring 4, the force of the torsion spring 4 can make the locking member 20 slide along the side of the stopper 5 of the electric opening arm 1 under the pull of the first toggle plate 2 and the second toggle plate 3 and reach the unlocking position P1. When closing the door again, it is necessary to perform the process of driving the locking member 20 to the locking position P2 through the locking unit 50 again, which is cumbersome and inconvenient in actual use. If the driver forgets this step, it is easy to cause a safety hazard that the door cannot be effectively closed after the vehicle starts.

[0050] Compared with the above-mentioned related technologies, the embodiment of the present disclosure, by setting an avoidance area 301 on the first driving component, can start the locking unit 50 only once after the electronic control fails to move the locking member 20 to the locking position P2, so that the lock seat 10 is reset, and the locking member 20 can operate normally between the locking position P2 and the unlocking position P1. There is no need to start the locking unit 50 every time the first-level lock of the door is closed, which simplifies repetitive operations, is easy to use, and effectively solves the safety hazard of the door failing to be effectively closed after the vehicle starts.

[0051] According to some embodiments, reference Figure 2 and Figure 3 The main body may include an operating member 32 and a pushing member 33 connected to the operating member 32. The protruding member 31 may be located at an end of the pushing member 33 away from the operating member 32. The protruding member 31, the operating member 32 and the pushing member 33 together form a clearance area 301. In this embodiment, the operating member 32 is used to connect the pushing member 33, the power component 60 and the operating shaft L1. The pushing member 33 can drive the protruding member 31 to push the locking member 20 to move along a preset direction. The clearance area 301 formed by the protruding member 31, the operating member 32 and the pushing member 33 can provide sufficient movement space for the locking member 20 after the output of the power component 60 fails, so as to ensure the free rotation of the lock seat 10, thereby ensuring the free opening and closing of the door.

[0052] For example, the protrusion 31 can be integrally formed with the pushing member 33 to facilitate assembly processing of the electric drive member 30. The integral molding setting can also increase the connection strength between the protrusion 31 and the pushing member 33, reduce wear and tear, and thus extend the service life of the electric drive member 30.

[0053] In some embodiments, reference Figure 3 The electric drive member 30 may include a first elastic member 34 , and the pushing member 33 may be elastically connected to the operating member 32 via the first elastic member 34 , so that the locking member 20 can reach the unlocking position P1 after pushing the operating member 32 .

[0054] In the above embodiment, the output failure of the power component 60 may occur at any time, and the electric drive member 30 may also be stuck at any rotation position. When the electric drive member 30 is stuck and the locking member 20 falls into the air avoidance area 301, if the push member 33 prevents the locking member 20 from reaching the unlocking position P1, the first elastic member 34 can allow the locking member 20 to push the push member 33 and continue to move until it reaches the unlocking position P1, thereby ensuring the normal use of the secondary door lock. At the same time, when the locking member 20 moves to the locking position P2, the locking member 20 and the push member 33 are separated from the abutment state, and the first elastic member 34 can reset the push member 33 and maintain it in the reset position through elastic potential energy, that is, the push member 33 can automatically reset, and it always has a tendency to return to its initial state. In this way, it can be ensured that when the electric control system returns to normal, the push member 33 can re-abut and push the locking member 20 when the operating member 32 rotates, thereby driving the lock seat 10 to rotate in a preset direction to unlock the primary door lock.

[0055] According to some embodiments, reference Figure 3 The pusher 33 can be rotatably connected to the operating member 32 via the first pin shaft 35, that is, the pusher 33 is rotatably connected to the operating member 32. When the electric control fails or the motor fails, the electric drive member 30 pushes the locking member 20 to rotate to a certain angle along the preset direction and then gets stuck. The locking member 20 falls into the air avoidance area 301. At this time, the pusher 33 blocks part of the path of the locking member 20 sliding to the unlocking position P1. The locking member 20 can drive the pusher 33 to rotate around the first pin shaft 35 to expose the blocked part of the path, so that the locking member 20 can reach the unlocking position P1, ensuring the normal use of the secondary lock function.

[0056] In some embodiments, the operating member 32 may be provided with a protrusion 321, such as Figure 3As shown, one end of the first elastic member 34 can be connected to the boss 321, and the other end can be connected to the push member 33, and is located at the opposite end of the convex member 31 compared to the first pin 35, so that the convex member 31 and the boss 321 are relatively arranged with the first pin 35 as the center, forming a lever structure, so that the push member 33 can rotate around the first pin 35 under the push of the locking member 20, and can rotate and reset around the first pin 35 under the elastic potential energy of the first elastic member 34 when the locking member 20 and the push member 33 are out of contact. Among them, the first elastic member 34 can be a torsion spring sleeved on the boss 321, with a simple structure, good fixing effect, and stable torsion.

[0057] For example, refer to Figure 3 , the operating member 32 may be provided with a limiting hole 322, and the pushing member 33 may have a stopper 331 extending into the limiting hole 322, and the limiting hole 322 may limit the stopper 331 within a preset travel range. In this embodiment, the limiting hole 322 on the operating member 32 may be used to limit the rotation amount of the pushing member 33, the stopper 331 of the pushing member 33 extends into the limiting hole 322, and the rotation travel of the stopper 331 is the rotation travel of the pushing member 33, so as to avoid the pushing member 33 from rotating too much to cause damage to the first elastic member 34 or elastic failure, and even to cause the locking member 20 at the unlocking position P1 to be out of engagement, etc.

[0058] According to some embodiments, reference Figure 2 and Figure 3 The lock base 10 may also have a locking position P2. The lock base 10 has a first elongated hole 11 for the locking member 20 to slide between the unlocking position P1 and the locking position P2. The sliding of the locking member 20 in the first elongated hole 11 always has a tendency to slide to one end, that is, before sliding to a certain position, the locking member 20 may always tend to slide to one of the unlocking position P1 and the locking position P2, and after sliding through the position, it always tends to slide to the other of the unlocking position P1 and the locking position P2, so as to ensure that the locking member 20 will not stop at a non-end position of the first elongated hole 11, causing damage to or failure of the use function of the secondary door lock.

[0059] In some embodiments, reference Figure 4 The lock assembly mechanism may further include a second driving member 40, which is used to drive the locking member 20 to move between its unlocking position P1 and locking position P2. In this embodiment, the second driving member 40 can be used to toggle the locking member 20 to switch between the unlocking position P1 and the locking position P2, and the second driving member 40 always has a tendency to toggle the locking member 20 to one of the unlocking position P1 and the locking position P2, so as to avoid the locking member 20 stopping somewhere between the unlocking position P1 and the locking position P2, which affects the normal use of the secondary door lock.

[0060] For example, refer to Figure 4 , the second driving member 40 may include a toggle plate 41, a second pin 42 and a second elongated hole 43. The toggle plate 41 may include a second pin 42 for rotatably connecting with the locking unit 50 and a second elongated hole 43 for the locking member 20 to slide in a preset direction. Here, the second elongated hole 43 slides substantially in a preset direction. In this embodiment, the toggle plate 41 rotates under the drive of the locking unit 50 through the second pin 42, and pushes the locking member 20 to slide in the second elongated hole 43 during the rotation process. At the same time, the toggle plate 41 is provided with a second elongated hole 43 at one end connected to the locking member 20, so that when the locking member 20 is pushed by the electric drive member 30 and moves in a preset direction, it can slide in the second elongated hole 43 to meet the rotation action of the locking member 20 and the lock seat 10.

[0061] It should be noted that the locking member 20 can pass through the first elongated hole 11 and the second elongated hole 43 in sequence, so that the movement trajectory of the locking member 20 can generally include three parts: a first part that can be pushed by the electric driver 30, a second part that slides in the first elongated hole 11, and a third part that slides in the second elongated hole 43. The above three parts can combine the electric driver 30, the lock seat 10 and the second drive member 40, thereby simplifying the transmission structure.

[0062] For example, refer to Figure 4 The toggle plate 41 may be an integrated structure to ensure that the second driving member 40 has good structural strength in the process of transmitting the driving force of the locking unit 50, is not prone to breakage or falling off, and ensures the stability of the rotating structure.

[0063] According to some embodiments, the second driving member 40 may include a first toggle sub-plate connected to the locking unit 50, and a second toggle sub-plate rotatably connected to the first toggle sub-plate via a second elastic member. Figure 4 The toggle plate 41 in the embodiment is split into two parts connected by a second elastic member, that is, similar to Figure 1The scheme of connecting the first toggle plate 2 and the second toggle plate 3 through the torsion spring 4 in the embodiment can also achieve the effect of the above-mentioned toggle plate 41 by adaptively arranging the setting positions of the components. In this embodiment, the locking member 20 can be slidably connected to the second toggle sub-plate, wherein, in at least a part of the travel of the locking member 20 moving from the locking position P2 to the unlocking position P1, the second elastic member has a tendency to drive the locking member 20 to the unlocking position P1. In this embodiment, the locking unit 50 transmits power to the locking member 20 through the first toggle sub-plate and the second toggle sub-plate in sequence, and the first toggle sub-plate is connected to the second toggle sub-plate through the second elastic member, and can drive the locking member 20 to move from the locking position P2 to the unlocking position P1 at least part of the travel through the elastic potential energy, and maintain the movement tendency toward the unlocking position P1, so as to prevent the locking member 20 from failing to reach the unlocking position P1 and stopping at a certain position in the travel, thereby affecting the use function of the secondary door lock.

[0064] In some embodiments, reference Figure 4 , the locking unit 50 may include a locker 501, a driving part 502 and a toggle spring 503. The toggle spring 503 may be connected between the locker 501 and the driving part 502, so that the driving part 502 may have a tendency to move toward the first working position when it is located between the first working position and the intermediate position, and has a tendency to move toward the second working position when it is located between the second working position and the intermediate position, wherein the intermediate position is located between the first working position and the second working position, and wherein when the driving part 502 is located at the first working position, the locking member is located at the locking position P2, and when the driving part 502 is located at the second working position, the locking member 20 is located at the unlocking position P1, so that the locking member 20 has a tendency to move toward one of the unlocking position P1 and the locking position P2.

[0065] For example, refer to Figure 4 The second pin shaft 42 is rotatably and slidably connected to the mounting hole 51 on the locking unit 50, so that the toggle plate 41 can rotate around the second pin shaft 42 while sliding along the extension direction of the mounting hole 51, thereby ensuring that there is sufficient toggle space for the locking member 20 to move between the unlocking position P1 and the locking position P2, with a high degree of freedom.

[0066] In some embodiments, the second pin 42 can be disposed at one end of the toggle plate 41, and the second elongated hole 43 can be disposed at the other end of the toggle plate 41. Figure 4As shown, the toggle plate 41 plays a role in transmitting driving force between the locking unit 50 and the locking piece 20. Therefore, the second pin shaft 42 for connecting with the locking unit 50 and the second long hole 43 for connecting with the locking piece 20 are respectively arranged on both sides of the toggle plate 41 to satisfy the driving effect of the locking unit 50 on the locking piece 20. The arrangement is relatively reasonable and can reasonably utilize the plate body length of the toggle plate 41. The rotation radius is large and the torque is large, thereby improving the driving effect of the locking unit 50 on the locking piece 20.

[0067] To better explain the operating principle of the lock assembly mechanism provided by the embodiment of the present disclosure, Figures 2 to 5 The various structures and their connection and coordination relationships of a specific example are described as follows:

[0068] First, the first-level lock of the vehicle door must be unlocked when the second-level lock safety is released. The locking member 20 slides in the first elongated hole 11 of the lock seat 10 to switch between the locked position P2 and the unlocked position P1, so that the second-level lock of the vehicle door can be activated or released. At the same time, a pull-wire structure (not shown in the figure) for controlling the opening of the front and rear door locks (i.e., the first-level lock) is also provided on the other side of the lock seat 10 that is symmetrically arranged relative to the rotation center of the first elongated hole 11. When the side of the lock seat 10 with the first elongated hole 11 rotates in a preset direction, the lock seat 10 plate rotates as a whole and controls the opening of the first-level lock of the vehicle door through the front and rear door lock pull-wire structures, thereby completing the opening action of the vehicle door.

[0069] When the door is unlocked, the electric drive member 30 is first driven by the power component 60 to rotate, and the pushing member 33 and the protruding member 31 provided on the operating member 32 gradually abut against the side of the locking member 20 located in the unlocking position P1. Under the continuous driving of the power component 60, the pushing member 33 continuously pushes the locking member 20 to drive the lock seat 10 to rotate counterclockwise around the operating axis L1 in a preset direction. At the same time, the plate body of the lock seat 10 drives the door lock cable structure to control the opening of the first-level lock of the door. After the door is opened, the motor structure included in the power component 60 is reversed to make the operating member 32 connected to the motor structure by the cable rotate clockwise around the operating axis L1 under the opposite driving force. The operating member 32 drives the pushing member 33 to rotate in the opposite direction. The locking member 20 loses the driving force, and the lock seat 10 rotates clockwise and resets in the preset direction through the torsion spring structure or other reset force structure provided on the operating axis L1. At this point, the door is electrically opened.

[0070] If the power component 60 fails during the electric door opening process, resulting in the failure of the electric control of the electric opening system, the operating member 32 and the pusher 33 keep pushing the locking member 20 and are stuck and immobilized at a certain rotation angle, and the lock seat 10 cannot be normally reset in the state of rotating in the preset direction due to the continuous pushing action of the pusher 33, so that the front and rear door lock cables set on the plate body of the lock seat 10 continue to perform the door opening action, and the door cannot be normally closed. To solve this problem, it is necessary to start the locking unit 50 to rotate in the locking direction. The locking unit 50 drives the second driving member 40 to rotate through the second pin 42. When the toggle plate 41 rotates, it can push the locking member 20 located in the second long hole 43 to slide in the first long hole 11 of the lock seat 10 and move from the unlocking position P1 to the locking position P2, so that the locking member 20 is out of the contact state with the pusher 33, and the lock seat 10 can be rotated and reset in the preset direction, thereby releasing the continuous door opening action of the front and rear door lock cables, and the door can be normally closed at this time.

[0071] Thereafter, if the vehicle door is to be opened, due to a failure of the electric opening system, the vehicle door can be opened by a manual handle structure arranged in parallel with the electric opening system. The specific operation is as follows: start the locking unit 50, and move the locking member 20 from the locking position P2 to the unlocking position P1 through the second driving member 40 to release the secondary lock insurance. Then, the manual handle structure can pass through the electric driving member 30 to push the lock seat 10 plate to rotate in a preset direction, and the front and rear door lock cables located on the lock seat 10 plate control the opening of the vehicle door primary lock. It should be emphasized that since the electric drive member 30 is still stuck in a rotation position at a certain angle, the locking member 20 will fall into the air avoidance area 301 when moving from the locking position P2 to the unlocking position P1. When the driving force of the locking unit 50 is much greater than the torque of the first elastic member 34 connected to the push member 33, the locking member 20 is pulled by the toggle plate 41 to push the push member 33 in the movement direction of the locking member 20 in the first long hole 11. Although the push member 33 blocks part of the sliding path of the locking member 20, it does not hinder the sliding movement of the locking member 20. The locking member 20 can normally reach the unlocking position P1 to release the safety of the secondary lock of the car door, and the manual handle structure can normally open the primary lock of the car door to open the car door.

[0072] At the same time, although the electric opening system fails, the locking member 20 can still operate normally in the first long hole 11, and does not affect the rotation of the lock seat 10 in the preset direction. Therefore, after the vehicle door is opened, there is no need to start the locking unit 50 once before each door closing operation to push the locking member 20 back to the locking position P2 to allow the lock seat 10 to rotate and reset. The failure of the electric control does not affect the normal use of the manual handle, which simplifies unnecessary repetitive operations, is more convenient to use, and can effectively solve the safety hazard of the door failing to be effectively closed after the vehicle starts.

[0073] In a second aspect of an embodiment of the present disclosure, a vehicle door is provided, comprising a lock assembly mechanism described in the first aspect of the above embodiment, and thus has all the beneficial effects of the lock assembly mechanism described in the above embodiment, which will not be elaborated herein.

[0074] In the third aspect of the embodiment of the present disclosure, a vehicle is also provided, including a vehicle door described in the second aspect of the embodiment of the present disclosure, so it has all the beneficial effects of the vehicle door described in the above embodiments, and no further details will be given here.
