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," above, "" upper, "" above, "" higher, "and" side (e.g., as in "sidewall") to describe one component's relationship to another (other) component as shown 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.

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 100, a deadbolt assembly 200, and a pawl assembly 300.

The lock body 100 may be formed as a housing portion of the lock system of the present disclosure, which may include, for example, a back plate, a cover, etc., and accordingly, the latch bolt assembly 200 and pawl assembly 300, etc., may be mounted to the back plate and/or cover. The mounting manner of these components may be implemented in a manner known in the art, and this disclosure will not be repeated here.

In some embodiments of the present disclosure, the bolt assembly 200 is rotatably disposed to the lock body 100, and the bolt assembly 200 may be positioned in a full lock position, a half lock position, and an unlocked position, in other words, the bolt assembly 200 is capable of moving to one of the full lock position, the half lock position, and the unlocked position when the bolt assembly 200 is driven to rotate.

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 the shackle to rotate clockwise in the state shown in fig. 5, and the tongue component 200 can rotate from the unlocked position shown in fig. 1 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.

In addition, the latch bolt assembly 200 of the present disclosure is able to detect its position by a micro switch.

The unlocking process will be described below in connection with the sequence of fig. 1 to 5.

During unlocking, the bolt assembly 200 may be rotated in a counter-clockwise direction from the fully locked position shown in fig. 1 by a return force (which may be provided by a bolt assembly return spring, such as a coil spring) whereby the bolt assembly 200 may be rotated from the fully locked position shown in fig. 1 to the semi-locked position shown in fig. 3, and further, when the pawl assembly 300 does not limit the position of the bolt assembly 200, the bolt assembly 200 may 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 tongue component according to one embodiment of the present disclosure. Fig. 8 is a schematic view of another angle of fig. 7.

As shown in fig. 1 to 8, in the present disclosure, the latch bolt assembly 200 includes a U-shaped groove 210, the U-shaped groove 210 of the latch bolt assembly 200 is used to cooperate with a latch or the like provided on a vehicle body to implement a locking function, and in some embodiments of the present disclosure, the latch can be stably held in the U-shaped groove 210 when the latch bolt assembly 200 is in a fully locked position, the latch can still be positioned in the U-shaped groove 210 when the latch bolt assembly 200 is in a half-locked position, and the latch can be released by the latch bolt assembly 200 when the latch bolt assembly 200 is in an unlocked position, and the latch can be released from the U-shaped groove 210 of the latch bolt assembly 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, and more specifically, the latch bolt first feature 201 is located on a first side (lower side in FIG. 7) of the U-shaped slot 210, and correspondingly, the latch bolt 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 according to one embodiment of the present disclosure. Fig. 10 is a schematic view of the structure of fig. 9 at another angle.

In the present disclosure, as shown in fig. 1-5 and 9 and 10, pawl member 300 is rotatably disposed in lock body 100, pawl member 300 being capable of being in a first position, a second position and a third position, wherein pawl member 300 is capable of engaging first feature 201 of the locking bolt and maintaining locking bolt member 200 in the fully locked position when pawl member 300 is in the first position, pawl member 300 is capable of engaging second feature 202 of the locking bolt to maintain locking bolt member 200 in the semi-locked position when pawl member 300 is in the second position, and locking bolt member 200 is capable of being in the unlocked position when pawl member 300 is in the third position. In this 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 and second positions are the same position. During movement from the first position to the second position, the pawl member 300 can be rotated counterclockwise and release the tongue member 200, and then rotated clockwise and moved to the second position to retain the tongue member 200 in the second position in the orientation shown in fig. 1.

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 200 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 shown in fig. 1 with the pawl member 300 in a first position, wherein when the pawl member 300 is operated by an electric or manual actuator out of the first position, the pawl member 300 rotates in a counter-clockwise direction as shown in fig. 1, wherein in one case the pawl member 300 can be stopped directly in the second position, and in another case the pawl member 300 rotates in a clockwise direction after rotating in the counter-clockwise direction and rotates to the second position. Accordingly, when the pawl member 300 is in the second position, the tongue member 200 is able to rotate to the half-lock position under the force of the return 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 begins to move from the unlocked position, in turn, to the semi-locked position, the fully-locked position, during the movement of the bolt assembly 200, which may be driven by components such as the shackle described above, for example, to rotate clockwise, as viewed in fig. 5, and during the locking of the locking system, the pawl assembly 300 begins to move from the third position, in turn, to the second position, the first position (for example, to rotate clockwise, as viewed in fig. 5), under the force of the reset force.

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 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 includes a locking device 400 rotatably provided to the lock body 100 and for maintaining the pawl member 300 in the first position or the second position, and an operating member 500 rotatably provided to the lock body 100 for driving the locking device 400 to move. Preferably, the operating member 500 has the same rotational axis as the locking device 400, on the other hand, the rotational axes of the operating member 500 and the locking device 400 may also be different.

The present disclosure redesigns the mating manner and 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 enabling the locking system of the present disclosure to be conveniently arranged on different 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 fig. 11 at another angle. 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 fig. 13 at another angle.

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 the drawing), the locking device 400 will leave the first lock position.

In a preferred embodiment of the present disclosure, an operating portion second feature 502 is provided on the operating member 500, 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 a second end of the locking device 400) via the operating portion second feature 502, 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 is capable of being driven and rotated by the operating member 500, i.e. the operating member 500 cooperates with the pawl member 300 to drive the pawl member 300 in rotation after the operating member 500 has driven the locking means 400 in rotation and released the pawl member 300.

In one embodiment, when the first and second positions of the pawl member 300 are the same, the unlocking process of the lock device may not be via the second position, i.e. the operating member 500 may be able to directly drive the pawl member 300 to the third position, and accordingly the lock device may also be able to rotate directly from the fully locked 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 latch member 200 is moved out of the fully latched position, the pawl member 300 is forced against the latch member 200 by the restoring force and then moves to the second position shown in fig. 3, thereby holding the latch 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.

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.

In the present disclosure, the pawl member 300 is capable of exiting the range of motion path of the deadbolt member after it exits the first position or exits the second position, thereby enabling the deadbolt member to rotate in the unlocking direction.

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

During locking of the lock system, the bolt member 200 is actuated by a member such as a shackle, from an unlocked position to a semi-locked position, a fully locked position, when the pawl member 300 is out of contact with the end of the second arm of the bolt member 200, the pawl member 300 is able to move from a third position (the position in which the pawl member 300 is located in fig. 5) to a second position, a first position, under the influence of a return force (the pawl member return spring), the lock device 400 is rotated clockwise, i.e. in the direction of locking the pawl member 300, under the influence of a return force (e.g. the lock device return spring, which may be a coil spring), and when the lock device 400 is moved to the second locked position, the first end of the lock 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 operator member 500 is rotated clockwise under the influence of the return force (e.g. provided by the operator return spring), the operator fourth feature 504 will abut the 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 position when the pawl member 300 is in the second position.

In a preferred embodiment, the locking means 400 is rotatable relative to the operating member 500 and the locking means 400 is capable of abutting the operating portion second feature 502 under the force of a return spring or the like, and during locking the tongue member 200 is capable of driving the pawl member 300 out of the third position and further clockwise, at which time the pawl member 300 is capable of pushing the locking means 400 to rotate counter-clockwise and to move relative to the operating member 500, whereby the locking means 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 action of the restoring force and moves to the second position, and accordingly, the locking device 400 rotates clockwise under the action of the restoring force and moves to the position in close contact with the second feature 502 of the operating portion, and the locking device 400 is located at 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.

As shown in fig. 15, the operating member 500 of the present disclosure can be driven to rotate by the unlocking motor 101, and thus unlocking of the lock system is achieved. Specifically, the unlocking motor 101 can be provided to the lock body 100 and can be in driving connection with the unlocking gear 102. In a specific embodiment, the unlocking gear 102 is rotatably disposed on the lock body 100 and has an a-th axis, preferably the a-th axis of the unlocking gear 102 can be perpendicular or substantially perpendicular to the third axis of the operating member 500, thereby enabling the lock system of the present disclosure to be conveniently disposed within a door or the like of a motor vehicle.

In a preferred embodiment, the output shaft of the unlocking motor 101 is formed as a worm capable of meshing with teeth of the outer periphery of the unlocking gear 102, in which case the unlocking gear 102 may also be referred to as an unlocking worm wheel. In the present disclosure, the worm may be a triple worm, so that the worm and the unlocking gear 102 are not self-locked, that is, in the worm-and-worm gear transmission structure of the present disclosure, the unlocking gear 102 can be driven to rotate by the rotation of the worm, and conversely, when the unlocking gear 102 is driven to rotate, the worm can also be driven to rotate.

A cam 102A is formed at one end face in the axial direction of the unlocking gear 102, and a cam surface of the cam 102A is an outer peripheral surface of the cam 102A. When the unlocking gear 102 is driven to rotate, the outer circumferential surface of the cam 102A can drive the unlocking lever 103 to rotate, and unlocking of the lock system is achieved by contact of the unlocking lever 103 with the operating member 500.

In a specific embodiment, the unlocking lever 103 is rotatably provided to the lock body 100, and the unlocking lever 103 has a B-th axis, and the a-th axis is provided in parallel with the B-th axis and spaced apart by a certain distance.

In the present disclosure, the unlocking lever 103 may include an unlocking lever first feature 103A, wherein the unlocking lever first feature 103A may be formed as one arm portion of the unlocking lever 103, whereby the unlocking lever 103 can be applied with an unlocking moment by the cam 102A when the unlocking lever first feature 103A is in contact with a surface of the cam 102A and driven by the cam 102A.

Further, the unlocking lever portion 103 further includes an unlocking lever second feature 103B, and preferably, the unlocking lever second feature 103B is also formed as one arm portion of the unlocking lever portion 103, and the unlocking lever second feature 103B is capable of contacting the operating member 500 and driving the operating member 500 to rotate in the unlocking direction.

The lock system of the present disclosure can also be unlocked manually, specifically, the lock system of the present disclosure further includes an inwardly opened pull rod portion 104 rotatably disposed in the lock body 100, and accordingly the inwardly opened pull rod portion 104 has a C-th axis, wherein the C-th axis, the a-th axis and the B-th axis are all disposed in parallel and spaced apart by a preset distance.

More specifically, the inside open lever portion 104 has an inside open lever first feature 104A, the inside open lever first feature 104A can be formed as one arm portion of the inside open lever portion 104, whereby an inside open pull wire can be provided on the inside open lever first feature 104A, and the inside open lever portion 104 can be caused to rotate when an external force is applied to the inside open lever portion through the inside open pull wire. For example, the inside open lever portion 104 can rotate clockwise in the direction shown in fig. 4 when the lock system is opened. In addition, when the external force applied by the inside open stay lock is removed, the inside open stay portion 104 can be rotated counterclockwise by the restoring force of a restoring element such as a coil spring and held at a preset initial position.

The inside pull rod portion 104 further includes an inside pull rod second feature 104B, the inside pull rod second feature 104B also being formed as an arm of the inside pull rod portion 104, whereby the inside pull rod portion 104 is enabled to drive the unlocking lever portion 103 to rotate by the cooperation of the inside pull rod second feature 104B with the unlocking lever portion 103. More preferably, the unlocking lever portion 103 comprises an unlocking lever third feature 103C, and accordingly, the inside release lever second feature 104B is capable of mating with the unlocking lever third feature 103C.

In one embodiment, as shown in fig. 15, when the unlocking gear 102 rotates clockwise, the unlocking lever 103 can be driven to rotate counterclockwise and the operating member 500 can be driven to rotate in the unlocking direction, and when the inside opening lever 104 rotates clockwise, the unlocking lever 103 can also be driven to rotate counterclockwise and the lock system can be unlocked.

As shown in fig. 15 and 16, the lock system of the present disclosure further includes a super lock push rod portion 105 for pushing the unlocking lever portion 103 to rotate to a preset position where when the inside open lever portion 104 is driven and rotated, it cannot drive the unlocking lever portion 103 to rotate, i.e., the inside open lever portion 104 is not engaged with the unlocking lever portion 103.

Specifically, in the orientation shown in fig. 15, the super lock plunger 105 can be driven and moved to the left and can be in the position shown in fig. 16, and the super lock plunger 105 can engage the unlocking lever second feature 103B and push the unlocking lever portion 103 to rotate clockwise, at which time the unlocking lever third feature 103C will disengage from the envelope of the movement of the inside opening lever second feature 104B, and accordingly, even if the inside opening lever portion 104 is pulled, it will not drive the unlocking lever portion 103 to rotate, and accordingly the lock system will not be unlocked.

In other words, the super lock plunger 105 of the present disclosure can prevent the lock system from being opened by the inside open lever 104, i.e., when the super lock plunger 105 is in an operating state, the lock system cannot be opened by the inside open lever 104, thereby making the lock system safer.

On the other hand, when the super lock plunger 105 rotates after pushing the unlocking lever 103, the super lock plunger 105 can be restricted in position, so that the unlocking lever 103 cannot be driven to rotate, that is, at this time, even if power is supplied to the unlocking motor 101, the unlocking motor 101 cannot push the unlocking lever 103 to rotate, and accordingly unlocking cannot be achieved. That is, at this time, the lock system can be opened only by releasing the restriction of the super lock plunger 105 to the unlocking lever 103. On the other hand, when the unlocking motor 101 is energized and drives the unlocking lever 103 to rotate, the unlocking lever 103 can push the super lock plunger 105 to move, at which time the super lock plunger 105 can move rightward, and accordingly the super lock plunger 105 can only realize a function of preventing manual unlocking, which cannot prevent electric unlocking. In other words, the electric unlocking function of the lock system is always active regardless of the position of the super lock plunger 105.

As shown in fig. 17, the lock system further includes a super lock pushrod motor 121 and a super lock pushrod gear 122, wherein the super lock pushrod motor 121 can be energized and rotated, and an output shaft of the super lock pushrod motor 121 is provided with a worm, or the output shaft of the super lock pushrod motor 121 is formed as a worm, which can be engaged with teeth of an outer periphery of the super lock pushrod gear 122, and at this time, the super lock pushrod gear 122 may also be referred to as a super lock pushrod worm wheel. In the present disclosure, the worm may be a single-head worm or a multi-head worm, which will not be described in detail herein.

As shown in fig. 18, the super lock push rod gear 122 is formed as a sector gear, and accordingly, the super lock push rod gear 122 has a first end portion and a second end portion in a circumferential direction, wherein an outer extension portion 122A is provided at the first end portion in the circumferential direction of the super lock push rod gear 122, an elongated hole is provided in the outer extension portion 122A, and a length direction of the elongated hole, that is, a radial direction of the super lock push rod gear 122, wherein one end of the super lock push rod portion 105 is configured to cooperate with the unlocking lever portion 103, and the other end of the super lock push rod portion 105 includes a cylindrical portion slidably disposed in the elongated groove, whereby when the super lock push rod gear 122 rotates, a left-right movement of the super lock push rod portion 105 can be achieved.

In the disclosure, a first elongated slot is provided in the middle of the super lock push rod 105, the length direction of the first elongated slot of the super lock push rod 105 is the length direction of the super lock push rod 105, a first guide post may be provided on the lock body 100 and may move in the first elongated slot, a second elongated slot is also provided at the other end of the super lock push rod 105, the length directions of the first elongated slot and the second elongated slot are parallel, a second guide post may be provided on the lock body 100 and may move in the second elongated slot, and by means of the cooperation of the first guide post and the first elongated slot and the cooperation of the second guide post and the second elongated slot, the super lock push rod 105 may translate along a preset direction.

At this time, when the super lock pushrod motor 121 rotates in the forward or reverse direction, the super lock pushrod portion 105 can be driven to move leftward or rightward. On the other hand, the worm of the present disclosure and the super lock push rod gear 122 are not self-locked, that is, in the present disclosure, when the super lock push rod motor 121 rotates, the super lock push rod gear 122 can be driven to rotate, and in the reverse working process, when the super lock push rod gear 122 is driven to rotate, the worm can be driven to rotate.

In the present disclosure, a limiting portion 122B is further formed on an axial surface of the first end of the super lock push rod gear 122, and the limiting portion 122B can be matched with a limiting structure provided on the lock body 100 to limit a rotation angle of the super lock push rod gear 122, so as to prevent the super lock push rod gear 122 from being separated from the worm in a transmission connection relationship.

Referring again to fig. 16, the lock system of the present disclosure further includes a cylinder rod portion 123, the cylinder rod portion 123 having a D-th axis, wherein the D-th axis can be disposed in parallel with the first axis, thereby enabling the cylinder rod portion 123 to rotate when a user unlocks by a key or the like.

Specifically, the plug stem portion 123 of the present disclosure includes a plug stem first feature 123A, the plug stem first feature 123A being formed as one arm portion of the plug stem portion 123, and accordingly, the plug stem first feature 123A being capable of being coupled to and driven to rotate by a wire or the like.

Further, the lock cylinder lever portion 123 further includes a lock cylinder lever second feature 123B, such that the lock cylinder lever second feature 123B is formed as an arm of the lock cylinder lever portion 123 and the lock cylinder lever second feature 123B is located in a region between the first end and the second end of the super lock push rod gear 122 so that when the lock cylinder lever portion 123 is driven to rotate, it can push the super lock push rod gear 122 to rotate.

Specifically, in the orientation shown in FIG. 16, when the lock cylinder lever portion 123 is operated to rotate counterclockwise, the lock cylinder lever second feature 123B can drive the second end of the super lock plunger gear 122 and enable the super lock plunger gear 122 to rotate clockwise, and further, when the super lock plunger gear 122 rotates clockwise, can drive the super lock plunger portion 105 to move rightward, thereby releasing the unlocking lever portion 103, whereby the lock system is in an openable state, and accordingly, the lock system can be unlocked by the outside-open lever portion 133 described below, and of course, the creep system can also be unlocked by the inside-open lever portion 104 described above.

Fig. 19 is a schematic view of another angle of fig. 16. Fig. 20 is a schematic structural view of a lock system according to one embodiment of the present disclosure.

As shown in fig. 16 and 19, the lock system of the present disclosure further includes an emergency unlocking portion 131, the emergency unlocking portion 131 having an E-th axis, that is, the emergency unlocking portion 131 can be configured to rotate relative to the lock body 100, and in a preferred embodiment, the E-th axis can be parallel to the first axis.

In other words, the second end of the arcuate slot 131A is closer to the other end of the flared transition stem 132 than the first end of the arcuate slot 131A.

The cylindrical portion 132A is provided with a spring receiving portion 132B, and the spring receiving portion 132B may be formed with a groove, in which one end of a spring (e.g., a coil spring) may be received, and the other end of the spring may be disposed at the emergency unlocking portion 131, so that the cylindrical portion 132A may be held at the first end of the circular arc-shaped groove 131A by a restoring force provided by the spring.

In addition, the out-opening transition lever portion 132 further includes an out-opening transition lever first feature 132C, the out-opening transition lever first feature 132C may be formed as a limit structure, and accordingly, the super lock plunger portion 105 includes a protrusion feature, which can limit the position of the out-opening transition lever portion 132 when the super lock plunger portion 105 is in the working position, and prevent the out-opening pull lever portion 133 from driving the operation member 500 to rotate through the out-opening transition lever portion 132.

Meanwhile, the outside-open lever portion 133 is formed with a notch, at least part of the other end of the outside-open transition lever portion 132 is located in the notch of the outside-open lever portion 133, and the other end of the outside-open transition lever portion 132 is slidable in the notch. In other words, the travel of the flared transition bar 132 is within the depth of the slot, and no matter where the flared transition bar 132 is located, the other end thereof will not disengage from the slot.

In the state shown in fig. 16, the other end of the outside-open transition lever portion 132 is located in the notch of the outside-open lever portion 133 and does not engage with the end of the operating member 500, and at this time, when the inside of the outside-open lever portion 133 is driven to rotate clockwise, it does not drive the operating member 500 to rotate, and accordingly, the lock system is not unlocked.

When the emergency unlocking part 131 is driven to rotate clockwise, the outward opening transition rod part 132 can be pulled to move rightward, so that the other end of the outward opening transition rod part 132 slides in the notch and approaches the bottom wall of the notch, the other end of the outward opening transition rod part 132 can be matched with the end of the operating member 500, at this time, when the outward opening transition rod part 133 is driven to rotate clockwise, the outward opening transition rod part 132 can drive the operating member 500 to rotate, and accordingly, the lock system can be unlocked.

In the present disclosure, the lock system further comprises an intermediate transition lever portion 134, the intermediate transition lever portion 134 having a G-th axis, that is, the intermediate transition lever portion 134 being rotatable relative to the lock body 100, wherein the G-th axis is parallel to the first axis.

The intermediate transition lever portion 134 is configured to drive the emergency unlocking portion 131 to rotate, specifically, the intermediate transition lever portion 134 includes an intermediate transition lever first feature 134A, the intermediate transition lever first feature 134A may be formed as one wall portion of the intermediate transition lever portion 134, and a chute 134B having an opening is formed on the intermediate transition lever first feature 134A, an extending direction of the chute 134B is toward a G-th axis of the intermediate transition lever portion 134, that is, the chute 134B extends in a radial direction of the intermediate transition lever portion 134, an outer circumferential surface of the emergency unlocking portion 131 is provided with a slide post 131B, and the slide post 131B is slidably disposed in the chute 134B, whereby when the intermediate transition lever portion 134 is driven to rotate, it can drive the emergency unlocking portion 131 to rotate.

In the present disclosure, the intermediate transition rod portion 134 includes an intermediate notch 134C, the intermediate notch 134C including a first sidewall and a second sidewall along a circumferential direction of the intermediate transition rod portion 134, wherein the plug pull rod portion 123 includes a plug pull rod third feature 123C, the plug pull rod third feature 123C is formed as one wall portion of the plug pull rod portion 123, and the plug pull rod third feature 123C is located in the intermediate notch 134C, and is capable of contacting the first sidewall or the second sidewall when the plug pull rod portion 123 rotates, thereby pushing the intermediate transition rod portion 134 to rotate in different directions.

Specifically, taking the direction shown in fig. 16 as an example, when the lock cylinder lever portion 123 is operated to rotate counterclockwise, the lock cylinder lever third feature 123C can contact the first sidewall of the intermediate transition lever portion 134 and drive the intermediate transition lever portion 134 to rotate clockwise, and then the intermediate transition lever portion 134 will drive the emergency release portion 131 to rotate counterclockwise, thereby causing movement of the out-opening transition lever portion 132, at which time the lock system can be opened by the out-opening lever portion 133.

In the present disclosure, the lock cylinder lever portion 123 can be rotated clockwise by a reset element such as a torsion spring, and accordingly, it can drive the emergency unlocking portion 131 to rotate clockwise. The emergency unlocking portion 131 may be rotated counterclockwise by a return member such as a torsion spring.

Fig. 24 is a schematic structural view of an emergency unlocking portion of the lock system according to one embodiment of the present disclosure. Fig. 25 is a schematic structural view of a safety link portion of a lock system according to one embodiment of the present disclosure.

As shown in fig. 24 and 25, the lock system of the present disclosure further includes a safety link portion 141, and the safety link portion 141 is used to drive the emergency unlocking portion 131 to rotate. Specifically, in the present disclosure, the safety link portion 141 can be guided by the lock body 100 and moved in a preset direction, for example, and when the safety link portion 141 moves, it can push the emergency unlocking portion 131 to rotate.

Specifically, as shown in fig. 24, the emergency unlocking portion 131 includes a slide block 131C, the slide block 131C being capable of protruding upward from a plane in which the emergency unlocking portion 131 is located, and the slide block 131C having a lower portion in a cylindrical shape and an upper portion in a hemispherical shape, and enabling an axis of the slide block 131C to be parallel to a rotation axis of the emergency unlocking portion 131. In a preferred embodiment, the face of the slider 131C adjacent to the safety link portion 141 may be a plane.

An accommodating groove 141A is formed at one end of the safety link part 141, and the sliding block 131C is slidable within the accommodating groove 141A, so that when the safety link part 141 moves in a direction perpendicular to the rotation axis of the emergency unlocking part 131, it can apply a pushing force to the sliding block 131C, thereby rotating the emergency unlocking part 131.

Also, by providing the receiving groove 141A, the slide block 131C can be positioned at different positions of the receiving groove 141A when the emergency unlocking portion 131 is rotated, whereby the slide block 131C does not interfere with the safety link portion 141.

In one embodiment, the safety link portion 141 can be driven in rotation by a driving pawl portion 142. Specifically, the unlocking gear 102 is formed with a driving block 102B, and the driving block 102B is located at the other end of the unlocking gear 102 and is spaced apart from the rotation axis of the unlocking gear 102. In other words, the driving block 102B and the cam 102A are located at both ends of the unlocking gear 102 in the axial direction, respectively.

That is, the driving pawl 142 can be driven and rotated by the unlocking gear 102, and accordingly, the driving pawl 142 has an H-th axis that can be disposed in parallel with the rotation axis (i.e., a-th axis) of the unlocking gear 102.

In the present disclosure, the unlocking gear 102 has a first rotational direction and a second rotational direction, wherein the first rotational direction is opposite to the second rotational direction. In the present disclosure, in the direction shown in fig. 15, the first rotation direction is clockwise, and accordingly, when the unlocking gear 102 rotates in the clockwise direction, it can drive the unlocking lever 103 to rotate counterclockwise, and unlocking of the lock system is achieved.

Accordingly, in the direction shown in fig. 15, when the unlocking gear 102 rotates in the second direction, that is, the unlocking gear 102 is rotated counterclockwise. In the direction shown in fig. 27, the unlocking gear 102 rotates clockwise.

At this time, the driving jaw portion 142 includes a first driving piece 142A and a second driving piece 142B, the first driving piece 142A and the second driving piece 142B form a working space in which the driving block 102B of the unlocking gear 102 can be located, and selectively contact with the first driving piece 142A or the second driving piece 142B to drive the driving jaw portion 142 to rotate.

Specifically, as shown in fig. 27, when the unlocking gear 102 rotates clockwise, the driving block 102B can be engaged with the first driving piece 142A and apply a pushing force to the first driving piece 142A, thereby causing the driving pawl to rotate counterclockwise. In contrast, in operation, when the unlocking gear 102 is driven to rotate counterclockwise in the direction shown in fig. 27, i.e., in the first rotation direction, the driving block 102B can engage with the second driving piece 142B and apply a force to the second driving piece 142B, thereby rotating the driving pawl clockwise.

As shown in fig. 28, the other end of the safety link portion 141 is formed with a guide groove 141B, and in the present disclosure, the length direction of the guide groove 141B may be perpendicular to the movement direction of the safety link portion 141, or, in other words, the length direction of the guide groove 141B may be perpendicular to the length direction of the safety link portion 141. At this time, a cylindrical protrusion 142C is formed on the driving jaw 142, and the cylindrical protrusion 142C is slidably received in the guide groove 141B of the safety link portion 141, so that the safety link portion 141 can be driven to translate when the driving jaw 142 rotates.

Specifically, in the direction shown in fig. 27, when the driving claw portion 142 rotates counterclockwise, the safety link portion 141 can be driven to move leftward, and on the other hand, when the driving claw portion 142 rotates clockwise, it can drive the safety link portion 141 to move rightward. Further, when the safety link portion 141 is operated, the emergency unlocking portion 131 can be driven to rotate, and the driving process of the safety link portion 141 to the emergency unlocking portion 131 is described in detail above, which is not described in detail herein.

In a preferred embodiment, the first and second driving members 142A and 142B may have substantially the same structure, and hooks are formed at both ends of the first and second driving members 142A and 142B, and thus the size of the opening of the working space is smaller than the size of the inside of the working space, so that the driving pawl 142 can have a larger movement stroke when the unlocking gear 102 drives the driving pawl 142 to operate.

In the present disclosure, as shown in fig. 28, the safety link portion 141 further includes a safety link first feature 141C, which may be formed in a cylindrical shape, and the inside open lever portion 104 further includes an inside open lever third feature 104C, which may be formed as one wall portion of the inside open lever portion 104, and through which the inside open lever third feature 104C can push the safety link portion 141 to move, thereby enabling the outside open lever portion 133 to be used at the time of unlocking.

Referring again to fig. 26 and 27, the lock system of the present disclosure further includes a stopper 143, and the stopper 143 is guided by the lock body 100 and moves in a preset direction. In a preferred embodiment, the limiting member 143 can be driven by the driving pawl 142 and moved in a predetermined direction. Specifically, the driving pawl 142 includes a fork 142D, the fork 142D being capable of engaging with the stopper 143 and pushing the stopper 143 to a position where at least a portion of the stopper 143 interferes with the unlocking gear 102, and thereby being capable of being used to restrict rotation of the unlocking gear 102. For example, the limiting member 143 can cooperate with the cam 102A of the unlocking gear 102, whereby excessive movement of the unlocking gear in the second rotational direction can be blocked by the limiting member 143, i.e., the unlocking gear 102 cannot be rotated one revolution in the second rotational direction by the limiting member 143.

In the lock system disclosed by the invention, the half-locking pawl is not needed for limiting the lock tongue part, so that the structure of the lock system is simplified, and the cost of the lock system is reduced. And the reliability of the lock system of the present invention is better.

The lock system of the present disclosure further comprises a child protection link portion 151, the child protection link portion 151 being provided to be rotatable with respect to the lock body and having an operating position and a non-operating position, wherein when the child protection link portion 151 is located at the operating position, it is capable of preventing the unlocking lever portion 131 from rotating in the unlocking direction, and correspondingly when the child protection link portion 151 is located at the non-operating position, it is capable of allowing the unlocking lever portion 131 to rotate in the unlocking direction, at which time the system is capable of being unlocked.

More specifically, as shown in fig. 25, the child protection link portion 151 includes a limiting member 151A, the limiting member 151A may be formed in a cylindrical shape, and the unlocking lever portion 103 further includes an unlocking lever fourth feature 103D, and when the child protection link portion 151 is in the operating position, the limiting member 151A can block the unlocking lever fourth feature 103D, thereby preventing the unlocking lever portion 103 from rotating in the unlocking direction.

Fig. 30 is a schematic structural view of a safety link portion of a lock system according to another embodiment of the present disclosure. Fig. 31 is a schematic view of another angular configuration of a safety link portion of a lock system according to another embodiment of the present disclosure. Fig. 32 is a part view of a safety link portion of a lock system according to another embodiment of the present disclosure.

The present disclosure also provides another implementation of the safety link portion 141, specifically as shown in figure 32,

The safety link portion 141 further includes a safety link first feature 141C, wherein the safety link first feature 141C may be located at the other end of the safety link portion 141, the safety link first feature 141C may be formed in a cylindrical shape, and the inside open lever portion 104 further includes an inside open lever third feature 104C, the inside open lever third feature 104C may be formed as one wall portion of the inside open lever portion 104, and the safety link portion 141 may be pushed to move by the inside open lever third feature 104C, thereby enabling the outside open lever portion 133 to be used at the time of unlocking.

Unlike the above-described implementation, in the present implementation, the safety link portion 141 is not driven by the driving claw portion 142, that is, the lock system of the present implementation does not include the driving claw portion 142, and accordingly, the unlocking gear 102 does not include the driving block 102B or the like.

A rack structure 141D is formed on a surface of the middle portion of the safety link portion 141 near the unlocking gear 102, so that the safety link portion 141 is driven to be movable by engagement of the rack structure with teeth on the circumferential surface of the unlocking gear 102. Specifically, the safety link part 141 of the present disclosure includes a plurality of pillar structures thereon, and the safety link part 141 can move in a preset direction by the cooperation of the pillar structures with the guide grooves provided to the lock body, and when the unlocking gear 102 rotates, it can drive the safety link part 141 to reciprocate.

Specifically, when the unlocking gear 102 rotates in the first rotation direction (unlocking direction), the unlocking gear 102 rotates clockwise in the direction shown in fig. 30, and accordingly, the safety link portion 141 is driven and moves leftwards, at this time, the emergency unlocking portion 131 rotates and pushes the out-opening transition lever portion 132 to the rest position, at which time the lock device cannot be unlocked by the out-opening lever portion 133, but can be unlocked only by using the in-opening unlocking lever or the unlocking gear 102.

On the other hand, when the unlocking gear 102 rotates in the second rotation direction, i.e., counterclockwise as shown in fig. 30, and the safety link portion 141 is moved rightward, at this time, the emergency unlocking portion 131 rotates and pushes the out-opening transition lever portion 132 to the working position, at which time the lock device can be unlocked by the out-opening lever portion 133, thereby enabling a keyless entry or the like of the vehicle. That is, when the lock system of the present disclosure is used, the lock can be unlocked by the key through the lock cylinder pull rod portion, or by triggering a trigger switch and other structures provided on the vehicle door, so that the unlocking motor is electrified, and then the outward opening transition rod portion 132 is pushed to the working position.
