Description

Technical Field

[0001] This disclosure relates to a locking system and a motor vehicle, which can be applied to the cover or door of a motor vehicle, and belongs to the field of motor vehicle door lock technology. Background Technology

[0002] The biggest challenge facing electrically operated door locks is balancing the reliability of locking with the real-time speed of unlocking.

[0003] Chinese utility model patent CN217950058U discloses a locking device that significantly improves the reliability of the locking device by adding a locking mechanism. It also allows the engagement surfaces of the latch and pawl to be offset in the unlocking direction, enabling the electric release device to still achieve electric unlocking even under high sealing reaction forces.

[0004] However, this locking device places the two locking positions on one side of the U-shaped groove of the locking tongue component, which makes the locking tongue component too large and its strength is also challenged. In addition, the first operating component of the locking device is set separately from the locking component and has different rotation centers, requiring a large accommodation space.

[0005] Meanwhile, the locking device and operating component in the prior art have different axes of rotation. When the operating component drives both the locking device and the pawl component at the same time, the arrangement is difficult, which makes it impossible to further reduce the size of the lock body.

[0044] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0045] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0046] Unless otherwise stated, the exemplary implementations / embodiments shown are to be understood as providing exemplary features of various details that provide ways in which the technical concepts of this disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.

[0047] The use of crosshairs and / or shading in the accompanying drawings is generally used to clarify the boundaries between adjacent components. Thus, unless otherwise stated, the presence or absence of crosshairs or shading does not convey or indicate any preference or requirement for the specific material, material properties, dimensions, proportions, commonalities between the illustrated components, or any other characteristics, properties, etc., of the components. Furthermore, in the accompanying drawings, the dimensions and relative dimensions of components may be exaggerated for clarity and / or descriptive purposes. When exemplary embodiments can be implemented differently, a specific process sequence may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in the reverse order of their description. Furthermore, the same reference numerals denote the same components.

[0048] When a component is referred to as being "on" or "above" another component, "connected to," or "joined to" another component, the component may be directly on, directly connected to, or directly joined to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to," or "directly joined to" another component, there are no intermediate components. Therefore, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have intermediate components.

[0049] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” another component or feature would subsequently be positioned “above” said other component or feature. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0050] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, parts, components, and / or groups thereof. It should also be noted that, as used herein, the terms “substantially,” “about,” and other similar terms are used as approximate terms rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values ​​that would be recognized by one of ordinary skill in the art.

Figure 3 This is a schematic diagram of a locking system according to one embodiment of the present disclosure (the latch component is in the half-lock position). Figure 4 yes Figure 3 A structural diagram from another angle. Figure 5 This is a schematic diagram of a locking system according to one embodiment of the present disclosure (the latch component is in the unlocked position). Figure 6 yes Figure 5 A structural diagram from another angle.

[0052] like Figures 1 to 6 As shown, the locking system disclosed herein can be applied to the cover or door of a motor vehicle, thereby locking the cover or door of the motor vehicle to the vehicle body. For example, a latch can be provided on the vehicle body, and the locking system can hold the latch to lock the motor vehicle. Conversely, when the locking system releases the latch, it can unlock the cover or door of the motor vehicle.

[0053] In this disclosure, the locking system includes components such as a lock body, a bolt component 200, and a pawl component 300.

[0054] The lock body can be formed as the housing part of the lock system of this disclosure. For example, it may include a back plate (or base plate), a cover, and other structures. For example, the base plate in Chinese Utility Model Patent CN217950058U can be used as the lock body of this disclosure. Accordingly, components such as the bolt member 200 and the pawl member 300 can be installed on the base plate and / or the cover. The installation method of these components can be implemented using methods in the prior art, which will not be described in detail in this disclosure.

[0055] In some embodiments of this disclosure, the latch component 200 is rotatably disposed on the lock body, and the latch component 200 can be located in a fully locked position, a half-locked position, or an unlocked position; in other words, when the latch component 200 is driven to rotate, the latch component 200 can move to one of the fully locked position, the half-locked position, and the unlocked position.

[0056] More specifically, during the locking process of the lock system, in the initial state (when the lock system is in the unlocked state), the bolt member 200 is in the unlocked position. At this time, the bolt member 200 can be pushed by the latch (not shown), thereby... Figure 5 When rotated clockwise in the shown state, the latch component 200 can be moved from... Figure 5 The unlock position shown is rotated to Figure 3 The half-lock position is shown.

[0057] In some embodiments of this disclosure, the latch component 200 may also be connected to a structure such as a pull cable of an electric drive mechanism, thereby being driven by the electric drive mechanism to rotate. Thus, the lock system of this disclosure can achieve electric locking.

[0058] like Figure 3 As shown, when the latch component 200, which is in the half-lock position, continues to rotate clockwise driven by the latch, the latch component 200 will rotate from the half-lock position to the fully locked position, thereby completing the locking process of the lock system of this disclosure.

[0059] The following will combine Figures 1 to 5 This describes the unlocking process of the lock system disclosed herein.

[0060] During the unlocking process, the latch component 200 can be released by a return force (which can be provided by a return spring in the latch component, such as a coil spring). Figure 1 The fully locked position shown is rotated counterclockwise, thereby allowing the bolt component 200 to rotate from... Figure 1 The fully locked position shown is rotated to Figure 3 The semi-locked position is shown; furthermore, when the pawl member 300 does not restrict the position of the latch member 200, the latch member 200 can move from... Figure 3 The half-lock position shown is rotated to Figure 5 Follow the unlock position shown to complete the unlocking process.

[0061] Figure 7 This is a schematic diagram of the structure of a latch component 200 according to one embodiment of the present disclosure. Figure 8 yes Figure 7 Another angle ( Figure 7 (Structural diagram from the rear view).

[0062] like Figures 1 to 8As shown, in this disclosure, the latch component 200 includes a U-shaped groove 210. The U-shaped groove 210 of the latch component 200 is used to cooperate with components such as a latch mounted on the vehicle body to achieve a locking function. In some embodiments of this disclosure, when the latch component 200 is in the fully locked position, the latch can be stably held within the U-shaped groove 210; when the latch component 200 is in the half-locked position, the latch is still located within the U-shaped groove 210; when the latch component 200 is in the unlocked position (e.g., ...), ... Figure 5 As shown), the latch can be released by the latch component 200, and the latch can disengage from the U-shaped groove 210 of the latch component 200.

[0063] In some preferred embodiments of this disclosure, the latch component 200 includes a first latch feature 201 and a second latch feature 202, which are respectively located on both sides of the U-shaped groove 210; more specifically, the first latch feature 201 is located on the first side of the U-shaped groove 210. Figure 7 (lower side of the middle), correspondingly, the second feature 202 of the locking tongue is located on the second side of the U-shaped groove 210 ( Figure 7 (upper side of the middle). More preferably, both the first feature 201 and the second feature 202 of the latch are located near the opening of the U-shaped groove 210.

[0064] Figure 9 This is a schematic diagram of the structure of a pawl component 300 according to one embodiment of the present disclosure. Figure 10 yes Figure 9 A structural diagram from another angle (rear view).

[0065] In this disclosure, such as Figures 1 to 5 as well as Figure 9 and Figure 10 As shown, the pawl component 300 is rotatably disposed on the lock body. The pawl component 300 can be in a first position, a second position, and a third position. When the pawl component 300 is in the first position, it engages with the first feature 201 of the latch, holding the latch component 200 in the fully locked position. When the pawl component 300 is in the second position, it engages with the second feature 202 of the latch, holding the latch component 200 in the partially locked position. When the pawl component 300 is in the third position, the latch component 200 is in the unlocked position. In this disclosure, the first position and the second position can be the same position or different positions. In a preferred embodiment of this disclosure, the first position and the second position are the same position. During the movement from the first position to the second position (movement to the second position), ... Figure 1 In the direction shown, the pawl component 300 can first rotate counterclockwise to release the locking tongue component 200, and then rotate clockwise to move to the second position, holding the locking tongue component 200 in the half-locked position (e.g., Figure 3(As shown).

[0066] In other words, through the structural design of the latch component 200 (the first feature of the latch and the second feature of the latch are located on both sides of the U-shaped groove), the size of the latch component 200 and the size of the lock system can be significantly reduced, while the strength of the lock system in the fully locked state is improved.

[0067] Specifically, when the locking system of this disclosure is in a fully locked state (e.g.) Figure 1 As shown in the diagram, the latch component 200 is a simply supported beam structure, which significantly increases the strength of the latch component 200 compared to the cantilever beam structure of a traditional latch component in the fully locked position. Consequently, the latch component 200 of this disclosure is not easily damaged by external forces. Moreover, while meeting design requirements, the size of the latch component 200 can be reduced due to its simply supported beam structure.

[0068] like Figure 1 As shown in this disclosure, when the latch component 200 is in the fully locked position, both the first feature 201 of the latch and the pawl component 300 are located on the first side (lower side) of the U-shaped groove 210, such that components such as the latch (not shown) are located between the rotation axis of the pawl component 300 and the rotation axis of the latch component 200. Thus, the first arm of the latch component 200 ( Figure 1 The lower part of the U-shaped groove 210 (i.e., the right arm) forms a simply supported beam structure with the pawl component 300.

[0069] In some embodiments of this disclosure, the contact surface between the pawl member 300 and the first feature 201 of the latch (located on the first arm of the latch member) is formed as a generally planar surface (see reference). Figure 1 Correspondingly, the first feature 201 of the latch is also formed in a generally planar shape (see reference). Figure 1 Preferably, a stop surface 205 is formed on the first arm of the latch member 200. When the latch member 200 is in the fully locked position, the stop surface 205 can restrict further rotation of the pawl member 300 and prevent the pawl member 300 from disengaging from the first position.

[0070] In this disclosure, the pawl component 300 can be driven to rotate. The locking system is... Figure 1 As shown, the pawl component 300 is in the first position; when the pawl component 300 is disengaged from the first position by an electric actuator or a manual actuator, the pawl component 300 will move along... Figure 1The counterclockwise rotation shown can, in one case, cause the pawl component 300 to stop directly at the second position; in another case, after rotating counterclockwise, the pawl component 300 will rotate clockwise and reach the second position. Accordingly, when the pawl component 300 is in the second position, the locking tongue component 200 can rotate to the half-lock position under the action of the reset force.

[0071] When the pawl component 300 is further driven in the second position, the pawl component 300 disengages from the second position, i.e., it can move along... Figure 3 The pawl component 300 rotates counterclockwise as shown and reaches the third position. Correspondingly, when the pawl component 300 is in the third position, the bolt component 200 can rotate to the unlocked position under the action of the reset force, and the lock system is in the unlocked state.

[0072] During the locking process of the locking system, the pawl component 300 can be driven by a restoring force, such as a pawl component return spring (e.g., a coil spring), to disengage from the third position and move to the second and first positions. (Refer to...) Figure 5 The pawl component 300 can rotate clockwise under the action of the reset force (the bolt component 200 must first disengage from the unlocked position, as detailed below). During the locking process of the lock system, the bolt component 200 starts from the unlocked position and moves sequentially to the half-locked position and the fully locked position. During the movement of the bolt component 200, it can be driven by components such as the latch described above, for example by... Figure 5 The clockwise rotation begins during the locking process of the lock system. Under the action of the reset force, the pawl component 300 starts to move from the third position and then moves to the second and first positions in sequence.

[0073] In this disclosure, during the locking process of the lock system, the pawl component 300 can move clockwise under the action of the reset force, and correspondingly, it can also move counterclockwise under the drive of the bolt component 200, so that the pawl component 300 can move to one of the third position, the second position and the first position.

[0074] When the locking system is in the fully locked state (refer to) Figure 1 The stop surface 205 of the latch member 200 can restrict the pawl member 300 in the first position from further resetting and can prevent the pawl member 300 and the latch member 200 from disengaging.

[0075] In a preferred embodiment of this disclosure, the lock system further includes a locking device 400 and an operating component 500. The locking device 400 is rotatably disposed on the lock body and is used to hold the pawl component 300 in a first position or a second position. The operating component 500 is rotatably disposed on the lock body and is used to drive the locking device 400 to move. Preferably, the operating component 500 and the locking device 400 have the same axis of rotation.

[0076] This disclosure redesigns the cooperation method and structure of the locking device 400 and the operating component 500, forming an important aspect of the invention. The two are configured to have the same axis of rotation, which facilitates the arrangement of the locking device 400 and the operating component 500, reduces the size of the locking system, and allows the locking system to be easily applied to different types of vehicles, thus expanding the scope of application of the locking system.

[0077] In a preferred embodiment of this disclosure, the operating component 500 has a receiving area, and the locking device 400 is located within the receiving area of ​​the operating component 500 during operation. This structural design can prevent the locking device 400 from being touched by components other than the operating component 500 and the pawl component 300.

[0078] Figure 11 This is a schematic diagram of the structure of an operating component according to one embodiment of the present disclosure. Figure 12 yes Figure 11 A structural diagram from another angle (rear view). Figure 13 This is a schematic diagram of a locking device according to one embodiment of the present disclosure. Figure 14 yes Figure 13 A structural diagram from another angle (rear view).

[0079] The following text combines Figures 1 to 5 The unlocking process of the lock system disclosed herein shall be explained again.

[0080] Locking system in Figure 1 In the fully locked state shown, the first end of the locking device 400 holds the first end of the pawl component 300 in a position engaged with the first feature 201 of the locking tongue. At this time, the pawl component 300 is in the first position, and the locking device 400 is in the first locked position.

[0081] refer to Figure 1 and Figure 3 as well as Figures 11 to 14When the operating member 500 is subjected to an external force and rotates counterclockwise (for example, when the operating member 500 is subjected to an external force via the first feature 501 of the operating part, such as an electric actuator), the operating member 500 rotates in the direction in which the locking device 400 unlocks the pawl member 300, and drives the locking device 400 to rotate in the direction in which the locking on the pawl member 300 is released. Figure 1 (In the counterclockwise direction), the locking device 400 will leave the first locking position.

[0082] In a preferred embodiment of this disclosure, an operation portion second feature 502 is provided on the operation member 500, and the operation portion second feature 502 is located on the first side of the locking device 400. Figure 1 (Left side of the image) When the operating part 500 rotates counterclockwise (refer to the left side of the image), Figure 1 The locking device 400 is driven to rotate counterclockwise via the second feature 502 of the operating part (the locking device 400 is driven to rotate counterclockwise via the second end of the locking device 400), and the locking device 400 releases the pawl member 300.

[0083] When the pawl component 300 is driven to rotate counterclockwise, it can move from... Figure 1 The first position shown moves to Figure 3 The second position is shown. In a preferred embodiment, the pawl component 300 can be driven and rotated by the operating component 500. In other words, after the operating component 500 drives the locking device 400 to rotate and releases the pawl component 300, the operating component 500 cooperates with the pawl component 300 to drive the pawl component 300 to rotate.

[0084] In one embodiment, when the first and second positions of the pawl component 300 are the same, the unlocking process of the lock system can be bypassed by the second position. That is, the operating component 500 can directly drive the pawl component 300 to the third position. Correspondingly, the latch component 200 (or the lock system) can also be directly rotated from the fully locked position to the open position.

[0085] Correspondingly, when the operating component 500 rotates counterclockwise and then clockwise, it can release the pawl component 300. Correspondingly, when the latch component 200 leaves the fully locked position, the pawl component 300, under the action of the restoring force, will move tightly against the latch component 200 until... Figure 3 The second position is shown, thereby holding the latch component 200 in the half-lock position.

[0086] Locking system in Figure 3 In the partially locked state shown, when the operating component 500 is driven again and rotated counterclockwise again, it can drive the pawl component 300 from... Figure 3 The second position shown moves to Figure 5In the third position shown, the locking tongue component 200 moves to the position indicated by the reset force. Figure 5 The unlock position shown indicates that the lock system has been unlocked, and the lock system has reached the unlocked state.

[0087] In a preferred embodiment of this disclosure, the operating component 500 drives the pawl component 300 to rotate counterclockwise via the third feature 503 of the operating part, causing the pawl component 300 to leave the first position or the second position.

[0088] In a preferred embodiment of this disclosure, the operating member 500 is provided with an operating part fourth feature 504. When the locking system is in a half-locked state (the latch member 200 is in the half-locked position, and the pawl member 300 is in the second position), the first end of the pawl member 300 is held by the first end of the locking device 400, so that the pawl member 300 is stably held in the second position. The operating part fourth feature 504 holds the second arm of the latch member 200 (preventing the latch member 200 from continuing to rotate clockwise, such as...). Figure 3 As shown), the latch member 200 is stably held in the semi-locked position. Correspondingly, the third feature 203 of the latch (located at the end of the second arm of the latch member 200 and disposed opposite to the second feature 202 of the latch) cooperates with the fourth feature 504 of the operating part, so that the latch member 200 is held in the semi-locked position by the fourth feature 504 of the operating part and the first end of the pawl member 300.

[0089] In some embodiments of this disclosure, a U-shaped groove 210 as described above is formed between the first and second arms of the latch member 200.

[0090] Locking system in Figure 3 In the partially locked state shown, when the first feature 501 of the operating part is driven, causing the operating component 500 to rotate counterclockwise, the fourth feature 504 of the operating part will release its hold on the third feature 203 of the latch. Driven by the second feature 502 of the operating part, the locking device 400 rotates counterclockwise along with the operating component 500. The first end of the locking device 400 will release its hold on the first end of the pawl component 300. Driven by the third feature 503 of the operating part, the pawl component 300 moves to the third position, releasing its hold on the latch component 200. Under the action of the reset force, the latch component 200 moves to the unlocked position, thereby unlocking the lock system. The lock system reaches the unlocked state, as shown below. Figure 5 As shown.

[0091] During the unlocking process of the lock system, when the pawl component 300 is in the second position (refer to...) Figure 3If the force applied to the first feature 501 of the operating part disappears at this time, the operating part 500 will tend to rotate clockwise under the action of the operating part return spring (not shown, for example, a coil spring), and the fourth feature 504 of the operating part will abut against the third feature 203 of the locking tongue, thereby jointly holding the locking tongue part 200 in the half-lock position with the first end of the pawl part 300. At this time, the first end of the locking device 400 and the third feature 503 of the operating part together hold the pawl part 300 in the second position.

[0092] exist Figure 3 In the state shown (the locking system is in a half-locked state), when the operating part 500 is subjected to external force and rotated counterclockwise, the second feature 502 of the operating part drives the locking device 400 (drives the second end of the locking device 400), the locking device 400 rotates counterclockwise, and the locking device 400 will leave the second locked position. Figure 3 (Regarding the position of the locking device), the pawl component 300 is released, and the pawl component 300 is driven by the third feature 503 of the operating part to rotate counterclockwise, moving from the second position to the third position. Under the action of the reset force, the latch component 200 moves from the half-locked position to the unlocked position, and the locking system changes from... Figure 3 The state action shown Figure 5 In the state shown, the latch component 200 is in the unlocked position, and the latch in the U-shaped groove 210 will be released.

[0093] refer to Figure 5 and Figure 7 In some embodiments of this disclosure, the third feature 203 and the second feature 202 of the latch are both located at the end of the second arm of the latch component 200. When the pawl component 300 engages with the third feature 203 of the latch (when in contact), the latch component 200 remains in the unlocked position.

[0094] In a preferred embodiment of this disclosure, reference is made to the appendix of this disclosure. Figures 1 to 5 The first feature 501 of the operating unit described above in this disclosure is disposed on the third feature 503 of the operating unit described above in this disclosure.

[0095] In some embodiments of this disclosure, the third feature 503 of the operating part is in the form of an operating handle, and the first feature 501 of the operating part is in the form of a through hole. Any adjustments made by those skilled in the art to the structure or shape of the third feature 503 and the first feature 501 of the operating part under the guidance of the technical solutions of this disclosure fall within the protection scope of this disclosure.

[0096] In a preferred embodiment of this disclosure, the line connecting the third feature 503 and the fourth feature 504 of the operating part passes through the rotation axis (rotation axis, i.e., the third axis) of the operating member 500, or is adjacent to the rotation axis of the operating member 500. (See reference...) Figures 1 to 5 The rotation axis of the operating component 500 is located or approximately located between the third feature 503 and the fourth feature 504 of the operating section.

[0097] The following text combines Figures 1 to 5 To illustrate the locking process of the locking system disclosed herein.

[0098] During the locking process of the lock system, the bolt component 200 is driven by components such as the latch, moving from the unlocked position to the half-locked position and then to the fully locked position. When the pawl component 300 disengages from the end of the second arm of the bolt component 200, the pawl component 300, under the action of the return force (pawl component return spring), moves from the third position (…). Figure 5 The pawl component 300 moves from its initial position to the second position and then to the first position. Under the action of a restoring force (e.g., a locking device return spring, which could be a coil spring), the locking device 400 rotates clockwise, i.e., towards locking the pawl component 300. When the locking device 400 moves to the second locking position, the first end of the locking device 400 locks the pawl component 300 in the second position. Figure 3 As shown, during the process of the lock system moving from the unlocked state to the half-locked state, the operating part 500 rotates clockwise under the action of the reset force (for example, provided by the operating part reset spring), and the fourth feature 504 of the operating part abuts against the third feature 203 of the latch.

[0099] In some embodiments of this disclosure, at least a portion of the outer surface of the third arm of the latch member 200 (preferably, the third arm is formed by a lateral extension of the second arm) is formed as a guide surface 204. During the movement of the latch member 200 from the unlocked position to the semi-locked position, the fourth feature 504 of the operating part moves in close contact with the guide surface 204 of the latch member 200. More preferably, the guide surface is configured such that after the pawl member 300 is in the second position, the locking device 400 moves to the second locked position.

[0100] In a preferred embodiment, the locking device 400 is rotatable relative to the operating member 500, and under the action of a reset force provided by a return spring or the like, the locking device 400 is pressed against the second feature 502 of the operating part. During the locking process, the latch member 200 can drive the pawl member 300 away from the third position and rotate clockwise further. At this time, the pawl member 300 can push the locking device 400 to rotate counterclockwise and generate relative movement with the operating member 500. At this time, the locking device 400 will not move to the second locking position. Then, when the latch member 200 moves to the half-lock position, the pawl member 300 rotates counterclockwise under the action of the reset force and moves to the second position. Correspondingly, the locking device 400 can rotate clockwise under the action of the reset force and move to the position pressed against the second feature 502 of the operating part. At this time, the locking device 400 is in the second locking position.

[0101] In this disclosure, the locking device 400 can also rotate clockwise together with the operating member 500. The locking device 400 can hold the pawl member 300 in the second position, and correspondingly, the latch member 200 is held in the half-locked position, such as... Figure 3 As shown.

[0102] Furthermore, with Figure 3 Starting from the state shown, during the locking process of the lock system, the latch component 200 is further driven by components such as the latch. As the latch component 200 moves from the half-lock position to the fully locked position, the latch component 200 first directly drives the operating component 500 (the latch component 200 drives the operating component 500 via the fourth feature 504 of the operating part) to rotate counterclockwise. The second feature 502 of the operating part drives the second end of the locking device 400, so that the locking device 400 and the operating component 500 rotate counterclockwise synchronously. The locking device 400 disengages from the second locking position, releasing the lock on the pawl component 300. The pawl component 300 is driven by the third feature 503 of the operating part to rotate counterclockwise. The first end of the pawl component 300 disengages from the second feature 202 of the latch, so that the latch component 200 can continue to move towards the fully locked position under the drive of components such as the latch.

[0103] After the end of the first arm of the latch member 200 disengages from the first end side of the pawl member 300, the pawl member 300 continues to rotate clockwise under the action of the reset force (which can be provided by the pawl member reset spring) and moves to the first position, such as... Figure 1 As shown, during this process, the operating component 500 and the locking device 400 rotate clockwise under the action of their respective reset forces, and the locking device 400 moves to the first locking position. Figure 1(as shown in the image) locks the pawl component 300 in the first position. At this time, the fourth feature 504 of the operating part moves to the position directly opposite the U-shaped groove 210. Preferably, at this time, the fourth feature 504 of the operating part is located at the opening of the U-shaped groove 210, as shown in the image. Figure 1 As shown.

[0104] In this disclosure, during the process of the locking tongue component 200 moving from the half-lock position to the fully locked position, the pawl component 300 first moves away from the first position (rotates counterclockwise), and then moves towards the first position (rotates clockwise), so that the locking tongue component 200 is first released from the half-lock position and then locked again in the fully locked position.
