Detailed Description

The present disclosure is described in further detail below with reference to the drawings and the embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant content and not limiting of the present disclosure. It should be further noted that, for convenience of description, only a portion relevant to the present disclosure is shown in the drawings.

In addition, embodiments of the present disclosure and features of the embodiments may be combined with each other without conflict. The technical aspects of the present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Unless otherwise indicated, the exemplary implementations/embodiments shown are to be understood as providing exemplary features of various details of some ways in which the technical concepts of the present disclosure may be practiced. Thus, unless otherwise indicated, features of the various implementations/embodiments may be additionally combined, separated, interchanged, and/or rearranged without departing from the technical concepts of the present disclosure.

The use of cross-hatching and/or shading in the drawings is typically used to clarify the boundaries between adjacent components. As such, the presence or absence of cross-hatching or shading does not convey or represent any preference or requirement for a particular material, material property, dimension, proportion, commonality between illustrated components, and/or any other characteristic, attribute, property, etc. of a component, unless indicated. In addition, in the drawings, the size and relative sizes of elements may be exaggerated for clarity and/or descriptive purposes. While the exemplary embodiments may be variously implemented, the specific process sequences may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in reverse order from that described. Moreover, like reference numerals designate like parts.

When an element is referred to as being "on" or "over", "connected to" or "coupled to" another element, it can be directly on, connected or coupled to the other element or intervening elements may be present. However, when an element is referred to as being "directly on," "directly connected to," or "directly coupled to" another element, there are no intervening elements present. For this reason, the term "connected" may refer to physical connections, electrical connections, and the like, with or without intermediate components.

For descriptive purposes, the present disclosure may use spatially relative terms such as "under … …," under … …, "" under … …, "" lower, "" above … …, "" upper, "" above … …, "" upper "and" side (e.g., as in "sidewall") to describe one component's relationship to another (other) component as illustrated in the figures. In addition to the orientations depicted in the drawings, the spatially relative terms are intended to encompass different orientations of the device in use, operation, and/or manufacture. For example, if the device in the figures is turned over, elements described as "under" or "beneath" other elements or features would then be oriented "over" the other elements or features. Thus, the exemplary term "below … …" may encompass both an orientation of "above" and "below". Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. Furthermore, when the terms "comprises" and/or "comprising," and variations thereof, are used in the present specification, the presence of stated features, integers, steps, operations, elements, components, and/or groups thereof is described, but the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof is not precluded. It is also noted that, as used herein, the terms "substantially," "about," and other similar terms are used as approximation terms and not as degree terms, and as such, are used to explain the inherent deviations of measured, calculated, and/or provided values that would be recognized by one of ordinary skill in the art.

Fig. 2 is a schematic view of another angle of fig. 1. Fig. 3 is a schematic structural view of a lock system (with the tongue component in the half-lock position) according to one embodiment of the present disclosure. Fig. 4 is a schematic view of another angle of fig. 3.

As shown in fig. 1-6, the lock system of the present disclosure can be applied to a hood or door of a motor vehicle, thereby enabling the hood or door of the motor vehicle to be locked to a vehicle body. For example, the vehicle body may be provided with a catch, which the lock system is able to hold in order to effect the locking of the vehicle, and vice versa, when the lock system releases the catch, the unlocking of the hood or door of the vehicle can be effected.

In this disclosure, the lock system includes a lock body, a deadbolt assembly 200, and a pawl assembly 300.

The lock body may be formed as a housing portion of the lock system of the present disclosure, which may include, for example, a back plate (or referred to as a bottom plate), a cover body, or the like, and the bottom plate in chinese patent No. CN217950058U may be employed as the lock body of the present disclosure. Accordingly, the components of the latch bolt assembly 200 and the pawl assembly 300 may be mounted on the base plate and/or the cover, and the mounting manner of these components may be implemented in a manner known in the art, which is not described in detail herein.

In some embodiments of the present disclosure, the latch bolt assembly 200 is rotatably disposed to the lock body, and the latch bolt assembly 200 may be in a full lock position, a half lock position, an unlocked position; in other words, when the tongue component 200 is driven to rotate, the tongue component 200 is able to move to one of the full, half, and unlocked positions.

More specifically, in an initial state (lock system in an unlocked state) during a locking process of the lock system, the tongue component 200 is in an unlocked position, at which time the tongue component 200 can be pushed by a shackle (not shown) to rotate clockwise in the state shown in fig. 5, and the tongue component 200 can rotate from the unlocked position shown in fig. 5 to the half-locked position shown in fig. 3.

In some embodiments of the present disclosure, the latch bolt assembly 200 may also be coupled to a structure such as a pull wire of an electric drive mechanism to be driven by the electric drive mechanism to rotate, thereby enabling the lock system of the present disclosure to be electrically locked.

As shown in fig. 3, when the latch bolt assembly 200 in the half-lock position is driven by the shackle to continue to rotate in a clockwise direction, the latch bolt assembly 200 will rotate from the half-lock position to the full-lock position, thereby completing the locking process of the locking system of the present disclosure.

The unlocking process of the lock system of the present disclosure will be described below in conjunction with fig. 1 to 5.

During unlocking, the latch bolt assembly 200 may be rotated in a counter-clockwise direction from the fully latched position shown in fig. 1 by a return force (which may be provided by a latch bolt assembly return spring, such as a coil spring), whereby the latch bolt assembly 200 is capable of rotating from the fully latched position shown in fig. 1 to the semi-latched position shown in fig. 3; further, in the event that the pawl assembly 300 does not limit the position of the tongue assembly 200, the tongue assembly 200 can be rotated from the semi-locked position shown in fig. 3 to the unlocked position shown in fig. 5, completing the unlocking process.

Fig. 7 is a schematic structural view of a latch bolt assembly 200 according to one embodiment of the present disclosure. Fig. 8 is a schematic view of the structure of another angle (back view of fig. 7) of fig. 7.

As shown in fig. 1 to 8, in the present disclosure, the tongue part 200 includes a U-shaped groove 210, and the U-shaped groove 210 of the tongue part 200 is used to cooperate with a shackle or the like provided on a vehicle body to perform a locking function, and in some embodiments of the present disclosure, the shackle can be stably held in the U-shaped groove 210 when the tongue part 200 is in the full locking position; when the tongue component 200 is in the semi-locked position, the shackle is still located within the U-shaped slot 210; when the tongue portion 200 is in the unlocked position (as shown in fig. 5), the shackle can be released by the tongue portion 200 and the shackle can be removed from the U-shaped slot 210 of the tongue portion 200.

In some preferred embodiments of the present disclosure, the latch bolt assembly 200 includes a latch bolt first feature 201 and a latch bolt second feature 202, the latch bolt first feature 201 and the latch bolt second feature 202 being located on either side of the U-shaped slot 210, respectively; more specifically, the tongue first feature 201 is located on a first side (lower side in fig. 7) of the U-shaped slot 210, and correspondingly, the tongue second feature 202 is located on a second side (upper side in fig. 7) of the U-shaped slot 210. More preferably, both the tongue first feature 201 and the tongue second feature 202 are located near the opening of the U-shaped slot 210.

Fig. 9 is a schematic structural view of a pawl member 300 according to one embodiment of the present disclosure. Fig. 10 is a schematic view of the structure of another angle (back view) of fig. 9.

In the present disclosure, as shown in fig. 1-5 and 9 and 10, the pawl member 300 is rotatably disposed to the lock body, the pawl member 300 being capable of being in a first position, a second position and a third position, wherein when the pawl member 300 is in the first position, the pawl member 300 is capable of engaging the deadbolt first feature 201 and retaining the deadbolt member 200 in the fully-latched position; when the pawl member 300 is in the second position, the pawl member 300 can cooperate with the tongue second feature 202 to retain the tongue member 200 in the half-lock position; when the pawl assembly 300 is in the third position, the tongue assembly 200 can be in the unlocked position. In the present disclosure, the first position and the second position may be the same position or different positions. In a preferred embodiment of the present disclosure, the first position and the second position are the same position. During movement from the first position to the second position (movement to the second position), the pawl member 300 can be rotated counterclockwise and release the tongue member 200, and then rotated clockwise and move to the second position in the direction shown in fig. 1, holding the tongue member 200 in the semi-locked position (as shown in fig. 3).

In other words, in the present disclosure, through the structural design of the latch bolt component 200 (the latch bolt first feature and the latch bolt second feature are located at two sides of the U-shaped groove respectively), the size of the latch bolt component 200 and the size of the lock system of the present disclosure can be greatly reduced, and at the same time, the strength of the lock system in the fully locked state is improved.

Specifically, when the lock system of the present disclosure is in the fully locked state (as shown in fig. 1), the stress of the latch bolt assembly 200 is a simple beam structure, and compared to the cantilever beam structure stress of the conventional latch bolt assembly in the fully locked position, the strength of the latch bolt assembly 200 is greatly improved, and accordingly, the latch bolt assembly 200 of the present disclosure is not easily damaged by external forces. Moreover, the size of the tongue component 200 of the present disclosure is reduced because it is stressed in a simply supported beam configuration, while meeting design requirements.

As shown in fig. 1, in the present disclosure, when the latch bolt assembly 200 is in the fully latched position, the first latch bolt feature 201 and pawl assembly 300 are both located on a first side (underside) of the U-shaped slot 210, and such that a component (not shown), such as a shackle, is located between the axis of rotation of the pawl assembly 300 and the axis of rotation of the latch bolt assembly 200, whereby the first arm (the lower portion of the U-shaped slot 210 in fig. 1, the right arm) of the latch bolt assembly 200 forms a corbel structure with the pawl assembly 300.

In some embodiments of the present disclosure, the pawl member 300 is formed substantially planar with the latch bolt first feature 201 (located on the first arm of the latch bolt member) (see fig. 1), and accordingly, the latch bolt first feature 201 is also formed substantially planar (see fig. 1). Preferably, the first arm of the latch bolt assembly 200 has a stop surface 205 formed thereon, the stop surface 205 being capable of limiting further rotation of the pawl assembly 300 when the latch bolt assembly 200 is in the fully latched position, preventing the pawl assembly 300 from being disengaged from the first position.

In the present disclosure, the pawl member 300 can be driven to rotate. The lock system is in the state shown in fig. 1, with the pawl member 300 in the first position; when the pawl member 300 is operated by the electric or manual actuator from the first position, the pawl member 300 will rotate in a counter-clockwise direction as viewed in fig. 1, in which case the pawl member 300 can be stopped directly in the second position; in another case, the pawl member 300 rotates in a clockwise direction and rotates to the second position after rotating in a counterclockwise direction. Accordingly, when the pawl member 300 is in the second position, the tongue member 200 can be rotated to the half-lock position by the restoring force.

When the pawl member 300 is further driven in the second position, the pawl member 300 is disengaged from the second position, i.e., is able to rotate in a counterclockwise direction as viewed in fig. 3, and rotated to the third position. Accordingly, when the pawl assembly 300 is in the third position, the tongue assembly 200 can be rotated to the unlocked position by the return force and the lock system is in the unlocked state.

During the locking process of the locking system, pawl member 300 is capable of being urged out of the third position and toward the second, first position by a return force such as provided by a pawl member return spring (e.g., a coil spring), and pawl member 300 is rotatable clockwise (requiring latch member 200 to be initially disengaged from the unlatched position, as described in greater detail below) by the return force of fig. 5. During the locking of the locking system, the bolt assembly 200 is actuated from the unlocked position to the semi-locked position, in turn, to the fully-locked position, and during actuation of the bolt assembly 200, it may be actuated by a member such as the shackle described above, for example, to rotate clockwise from fig. 5, and during the locking of the locking system, the pawl assembly 300 is actuated from the third position to the second, first position, in turn, by the reset force of the pawl assembly 300.

In the present disclosure, during locking of the lock system, the pawl member 300 is capable of clockwise movement under the force of the return force and, correspondingly, counter-clockwise movement under the actuation of the tongue member 200 such that the pawl member 300 is capable of moving to one of the third position, the second position and the first position.

In the fully locked condition of the lock system (see fig. 1), the stop surface 205 of the tongue member 200 limits further resetting of the pawl member 300 in the first position and prevents disengagement of the pawl member 300 from the tongue member 200.

In a preferred embodiment of the present disclosure, the lock system of the present disclosure further comprises a locking device 400 and an operating member 500, wherein the locking device 400 is rotatably provided to the lock body and is used to hold the pawl member 300 in the first position or the second position; the operation member 500 is rotatably provided to the lock body for driving the locking device 400 to move. Preferably, the operating member 500 has the same axis of rotation as the locking device 400.

The present disclosure redesigns the mating manner and the mating structure of the locking device 400 and the operating member 500, which forms an important summary of the present disclosure, configures both to have the same rotation axis, in other words, the same rotation axis, and thereby facilitates the arrangement of the locking device 400 and the operating member 500 of the present disclosure, reduces the volume of the locking system of the present disclosure, thereby being capable of conveniently applying the locking system of the present disclosure to different types of vehicles, and increases the range of use of the locking system of the present disclosure.

In the preferred embodiment of the present disclosure, the operating member 500 is formed with a receiving area, and the locking device 400 is located within the receiving area of the operating member 500 during the operation, and by this structural design, the locking device 400 can be prevented from being touched by members other than the operating member 500 and the pawl member 300.

Fig. 11 is a schematic structural view of an operating member according to one embodiment of the present disclosure. Fig. 12 is a schematic view of the structure of another angle (back view) of fig. 11. Fig. 13 is a schematic structural view of a locking device according to one embodiment of the present disclosure. Fig. 14 is a schematic view of the structure of another angle (back view) of fig. 13.

The unlocking process of the lock system of the present disclosure is explained again below with reference to fig. 1 to 5.

In the fully locked condition of fig. 1, the first end of the locking device 400 maintains the first end of the pawl member 300 in engagement with the tongue first feature 201 when the pawl member 300 is in the first position and the locking device 400 is in the first locked position.

Referring to fig. 1 and 3 and fig. 11 to 14, when the operating member 500 is applied with an external force and rotated counterclockwise (e.g., the operating member 500 is applied with an external force such as by an electric actuator via the operating portion first feature 501), the operating member 500 rotates in a direction to unlock the pawl member 300 by the locking device 400 and drives the locking device 400 to rotate in a direction to unlock the pawl member 300 (counterclockwise in fig. 1), the locking device 400 will leave the first lock position.

In a preferred embodiment of the present disclosure, the operating member 500 is provided with an operating portion second feature 502, the operating portion second feature 502 being located on a first side (left side in fig. 1) of the locking device 400, and when the operating member 500 is rotated counterclockwise (refer to fig. 1), the locking device 400 is driven to rotate counterclockwise via the operating portion second feature 502 (the locking device 400 is driven via a second end of the locking device 400), and the locking device 400 releases the pawl member 300.

When the pawl member 300 is driven to rotate counterclockwise, it can move from the first position shown in FIG. 1 to the second position shown in FIG. 3. In a preferred embodiment, the pawl member 300 can be driven and rotated by the operating member 500, in other words, after the operating member 500 drives the locking means 400 to rotate and releases the pawl member 300, the operating member 500 cooperates with the pawl member 300 to drive the pawl member 300 to rotate.

In one embodiment, when the first and second positions of the pawl member 300 are the same, the unlocking process of the lock system may not be via the second position, i.e., the operating member 500 may be capable of directly driving the pawl member 300 to the third position, and accordingly, the tongue member 200 (or the lock system) may also be capable of rotating directly from the fully latched position to the open position.

Accordingly, when the operating member 500 is rotated counterclockwise and clockwise, the operating member 500 can release the pawl member 300, and accordingly, when the tongue member 200 is moved out of the fully latched position, the pawl member 300 moves against the tongue member 200 to the second position shown in fig. 3 under the force of the restoring force, thereby maintaining the tongue member 200 in the half-latched position.

In the semi-locked state of fig. 3, when the operating member 500 is driven again and rotated counterclockwise again, it can drive the pawl member 300 to move from the second position of fig. 3 to the third position of fig. 5, and the tongue member 200 is operated to the unlocked position of fig. 5 by the restoring force, thereby effecting unlocking of the lock system, and the lock system reaches the unlocked state.

In a preferred embodiment of the present disclosure, the operating member 500 drives the pawl member 300 to rotate counterclockwise via the operating portion third feature 503 such that the pawl member 300 moves away from the first position or away from the second position.

In a preferred embodiment of the present disclosure, the operating member 500 is provided with an operating portion fourth feature 504, such that when the lock system is in the semi-locked state (the latch member 200 is in the semi-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 such that the pawl member 300 is held stably in the second position, and the operating portion fourth feature 504 holds the second arm of the latch member 200 (blocks continued clockwise rotation of the latch member 200, as viewed in fig. 3), such that the latch member 200 is held stably in the semi-locked position. Accordingly, the deadbolt third feature 203 (located at the end of the second arm of the deadbolt assembly 200, disposed away from the deadbolt second feature 202) mates with the operator fourth feature 504 such that the deadbolt assembly 200 is held in the semi-locked position by the operator fourth feature 504 and the first end of the pawl assembly 300.

In some embodiments of the present disclosure, the U-shaped slot 210 described above is formed between the first and second arms of the tongue component 200.

In the semi-locked state of the lock system shown in fig. 3, when the operating portion first feature 501 is actuated such that the operating portion 500 rotates counterclockwise, the operating portion fourth feature 504 will release the retention of the third feature 203 of the locking bolt, the first end of the locking device 400 will release the retention of the first end of the pawl member 300 due to the operating portion second feature 502 being actuated counterclockwise, the pawl member 300 moves toward the third position due to the actuating portion third feature 503, the retention of the locking bolt member 200 is released, the locking bolt member 200 moves toward the unlocked position due to the restoring force, thereby unlocking the lock system, and the lock system reaches the unlocked state as shown in fig. 5.

During unlocking of the lock system, when the pawl member 300 is in the second position (see fig. 3), if the force applied to the operating portion first feature 501 at this time is lost, the operating portion 500 will have a tendency to rotate clockwise under the influence of the operating portion return spring (not shown, e.g., a coil spring), and the operating portion fourth feature 504 will abut the deadbolt third feature 203 to thereby hold the deadbolt member 200 in the semi-latched position in conjunction with the first end of the pawl member 300, at which point the first end of the locking device 400 cooperates with the operating portion third feature 503 to hold the pawl member 300 in the second position.

In the state shown in fig. 3 (the lock system is in the half-lock state), when the operating member 500 is applied with an external force and rotated counterclockwise, the operating portion second feature 502 drives the lock device 400 (drives the second end portion of the lock device 400), the lock device 400 rotates counterclockwise, the lock device 400 will leave the second lock position (the position in which the lock device is located in fig. 3), the pawl member 300 is released, the pawl member 300 is driven by the operating portion third feature 503 and rotates counterclockwise, and the second position moves toward the third position. The latch bolt assembly 200 is moved from the half-lock position to the unlock position by the restoring force, the lock system is moved from the state shown in fig. 3 to the state shown in fig. 5, the latch bolt assembly 200 is in the unlock position, and the shackle in the U-shaped slot 210 is released.

Referring to fig. 5 and 7, in some embodiments of the present disclosure, both the latch third feature 203 and the latch second feature 202 are located at the end of the second arm of the latch bolt assembly 200, and the latch bolt assembly 200 remains in the unlocked position when the pawl assembly 300 is engaged (in contact) with the latch third feature 203.

In a preferred embodiment of the present disclosure, the operating portion first feature 501 described hereinabove of the present disclosure is disposed on the operating portion third feature 503 described hereinabove of the present disclosure, with reference to fig. 1 to 5 of the present disclosure.

In some embodiments of the present disclosure, the third operating portion feature 503 is in the form of an operating handle, the first operating portion feature 501 is in the form of a through hole, and the adjustment of the structure or the shape of the third operating portion feature 503 and the first operating portion feature 501 by those skilled in the art in light of the technical solution of the present disclosure falls within the protection scope of the present disclosure.

In a preferred embodiment of the present disclosure, the line between the operating portion third feature 503 and the operating portion fourth feature 504 passes through the rotational axis (rotational axis, i.e., third axis) of the operating member 500, or is adjacent to the rotational axis of the operating member 500. Referring to fig. 1-5, the rotational axis of the operational component 500 is located or approximately located between the operational portion third feature 503 and the operational portion fourth feature 504.

The locking process of the lock system of the present disclosure is described below in connection with fig. 1-5.

During locking of the locking system, the bolt assembly 200 is actuated by a member such as a shackle, from an unlocked position to a semi-locked position, a fully locked position, and when the pawl assembly 300 is out of contact with the end of the second arm of the bolt assembly 200, the pawl assembly 300 can be moved from a third position (the position in which the pawl assembly 300 is shown in fig. 5) to a second position, a first position, under the influence of a return force (the pawl assembly return spring); the locking device 400 rotates clockwise, i.e. in the direction of the locking pawl member 300, under the influence of a return force (e.g. a locking device return spring, which may be a coil spring), and when the locking device 400 is moved to the second locking position, the first end of the locking device 400 locks the pawl member 300 in the second position, as shown in fig. 3, and during movement of the lock system from the unlocked state to the semi-locked state, the operating member 500 rotates clockwise under the influence of a return force (e.g. provided by an operating member return spring), and the operating member fourth feature 504 will abut against the locking bolt third feature 203.

In some embodiments of the present disclosure, at least a portion of the outer surface of a third arm of the latch bolt assembly 200 (preferably, the third arm is formed by a lateral extension of the second arm) forms a guide surface 204, and the operator fourth feature 504 moves against the guide surface 204 of the latch bolt assembly 200 during actuation of the latch bolt assembly 200 from the unlatched position to the semi-latched position. More preferably, the guide surface is configured to move the locking device 400 to the second locking position after the pawl member 300 is in the second position.

In a preferred embodiment, the locking device 400 is rotatable relative to the operating member 500, and the locking device 400 may be urged against the operating portion second feature 502 by a return force provided by a return spring or the like; during the locking process, the tongue member 200 can drive the pawl member 300 out of the third position and further rotate clockwise, at which time the pawl member 300 can urge the lock mechanism 400 to rotate counterclockwise and move relative to the operating member 500, at which time the lock mechanism 400 does not move to the second locking position. Then, when the latch bolt assembly 200 moves to the half-lock position, the pawl assembly 300 rotates counterclockwise under the force of the restoring force and moves to the second position, and accordingly, the locking device 400 rotates clockwise under the force of the restoring force and moves to the position where it is in close contact with the second feature 502 of the operating portion, and the locking device 400 is in the second locking position.

In the present disclosure, the locking device 400 is also capable of rotating clockwise with the operating member 500, and the locking device 400 is capable of holding the pawl member 300 in the second position and, correspondingly, the tongue member 200 is held in the semi-locked position, as shown in fig. 3.

Further, starting from the state shown in fig. 3, during the locking of the lock system, the bolt assembly 200 is further driven by, for example, a shackle, and during the movement of the bolt assembly 200 from the half-lock position to the full-lock position, the bolt assembly 200 first directly drives the operating member 500 (the bolt assembly 200 drives the operating member 500 via the operating member fourth feature 504) to rotate counterclockwise, the operating member second feature 502 drives the second end of the locking device 400, so that the locking device 400 rotates counterclockwise in synchronization with the operating member 500, the locking device 400 disengages from the second locking position, the pawl assembly 300 is unlocked, the pawl assembly 300 is driven by the operating member third feature 503 to rotate counterclockwise, and the first end of the pawl assembly 300 disengages from the bolt second feature 202, so that the bolt assembly 200 can continue to move to the full-lock position under the driving of the components such as the shackle.

After the end of the first arm of the latch bolt assembly 200 is out of contact with the first end side of the pawl assembly 300, the pawl assembly 300 continues to rotate clockwise under a return force (which may be provided by a pawl assembly return spring) and moves to a first position, as shown in fig. 1, during which the operating member 500 and the locking device 400 rotate clockwise under the respective return force, the locking device 400 moving to a first locking position (the position shown in fig. 1) locking the pawl assembly 300 in the first position, at which point the operating member fourth feature 504 moves to a position facing the U-shaped slot 210, preferably at which point the operating member fourth feature 504 is located at the opening of the U-shaped slot 210, as shown in fig. 1.

In the present disclosure, during movement of the latch bolt assembly 200 from the half-lock position to the full-lock position, the pawl assembly 300 moves away from the first position (counter-clockwise rotation) and then moves toward the first position (clockwise rotation), such that the latch bolt assembly 200 is released from the half-lock position and locked again in the full-lock position.
