It should also be noted that, for ease of description, only the parts related to the present disclosure are shown in the accompanying drawings.

It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in the present disclosure can be combined with each other. The technical solution of the present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

Unless otherwise specified, the exemplary embodiments/embodiments shown will be understood as providing exemplary features of various details of some ways in which the technical concept of the present disclosure can be implemented in practice. Therefore, unless otherwise specified, the features of the various embodiments/embodiments can be combined, separated, interchanged and/or rearranged without departing from the technical concept of the present disclosure.

The use of cross-hatching and/or shading in the accompanying drawings is generally used to make the boundaries between adjacent components clear. As such, unless otherwise specified, the presence or absence of cross-hatching or shading does not convey or indicate any preference or requirement for the specific materials, material properties, dimensions, proportions, commonalities between the components shown, and/or any other characteristics, attributes, properties, etc. of the components. In addition, in the accompanying drawings, the sizes and relative sizes of the components may be exaggerated for clarity and/or descriptive purposes. When the exemplary embodiments can be implemented differently, the specific process sequence can be performed in a different order than described. For example, two successively described processes can be performed substantially simultaneously or in an order opposite to the described order. In addition, the same figure numbers represent the same components.

When a component is referred to as being "on" or "over," "connected to," or "coupled to" another component, the component may be directly on, directly connected to, or directly coupled to the other component, or intervening components may be present. However, when a component is referred to as being "directly on," "directly connected to," or "directly coupled to" another component, there are no intervening components. For this purpose, the term "connected" may refer to a physical connection, an electrical connection, etc., with or without intervening components.

For descriptive purposes, the present disclosure may use spatially relative terms such as "under," "beneath," "under," "down," "over," "upper," "above," "higher," and "side (e.g., as in "sidewall")," to describe the relationship of one component to another (other) component as shown in the accompanying drawings. The spatially relative terms are intended to encompass different orientations of the device in use, operation, and/or manufacture in addition to the orientation depicted in the accompanying drawings. For example, if the device in the accompanying drawings is turned over, components described as "under" or "beneath" other components or features would subsequently be positioned "over" the other components or features. Thus, the exemplary term "under" can encompass both the "over" and "under" orientations. Furthermore, the device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations), and the spatially relative descriptors used herein should be interpreted accordingly.

The terms used here are for the purpose of describing specific embodiments, and are not intended to be restrictive. As used here, unless the context clearly indicates otherwise, the singular forms "one (kind, person)" and "said (the)" are also intended to include plural forms. In addition, when the terms "comprise" and/or "include" and their variations are used in this specification, it is explained that there are stated features, integral bodies, steps, operations, parts, assemblies and/or their groups, but it is not excluded that there are or add one or more other features, integral bodies, steps, operations, parts, assemblies and/or their groups. It should also be noted that, as used here, the terms "substantially", "approximately" and other similar terms are used as approximate terms and not as degree terms, so that they are used to explain the inherent deviations of the measured values, calculated values and/or the values provided that will be recognized by those of ordinary skill in the art.

FIG. 1 is a schematic diagram of the structure of a lock system according to an embodiment of the present disclosure (the lock tongue component is in the fully locked position). FIG. 2 is a schematic diagram of FIG. 1 from another angle. FIG. 3 is a schematic diagram of the structure of a lock system according to an embodiment of the present disclosure (the lock tongue component is in the half-locked position). FIG. 4 is a schematic diagram of the structure of FIG. 3 from another angle. FIG. 5 is a schematic diagram of the structure of a lock system according to an embodiment of the present disclosure (the lock tongue component is in the unlocked position). FIG. 6 is a schematic diagram of the structure of FIG. 5 from another angle.

As shown in Figures 1 to 6, the lock system of the present disclosure can be applied to the hood or door of a motor vehicle, so as to lock the hood or door of the motor vehicle to the vehicle body. For example, a lock buckle can be provided on the vehicle body, and the lock system can hold the lock buckle to achieve locking of the motor vehicle. In the opposite process, when the lock system releases the lock buckle, the hood or door of the motor vehicle can be unlocked.

In the present disclosure, the lock system includes a lock body 100 , a bolt component 200 , a pawl component 300 and other components.

The lock body 100 can be formed as the housing part of the lock system of the present disclosure, for example, it can include structures such as a back plate and a cover body, and accordingly, components such as a lock tongue component 200 and a pawl component 300 can be installed on the back plate and/or the cover body. The installation method of these components can be implemented in the prior art, and the present disclosure will not repeat them one by one.

In some embodiments of the present disclosure, the lock tongue component 200 is rotatably disposed on the lock body 100, and the lock tongue component 200 can be located in a fully locked position, a half-locked position, and an unlocked position; in other words, when the lock tongue component 200 is driven to rotate, the lock tongue component 200 can move to one of the fully locked position, the half-locked position, and the unlocked position.

More specifically, during the locking process of the lock system, in the initial state (the lock system is in the unlocked state), the lock tongue component 200 is in the unlocked position. At this time, the lock tongue component 200 can be pushed by the lock buckle, thereby rotating clockwise in the state shown in Figure 5. The lock tongue component 200 can be rotated from the unlocked position shown in Figure 1 to the semi-locked position shown in Figure 3.

In some embodiments of the present disclosure, the lock tongue component 200 may also be connected to a structure such as a pull wire of an electric drive mechanism, so as to be driven by the electric drive mechanism to rotate, thereby, the lock system of the present disclosure can achieve electric locking.

As shown in FIG. 3 , when the lock tongue component 200 in the semi-locked position is driven by the lock buckle to continue to rotate in the clockwise direction, the lock tongue component 200 will rotate from the semi-locked position to the fully locked position, thereby completing the locking process of the lock system of the present disclosure.

In addition, the locking tongue component 200 of the present disclosure can detect its position through a micro switch.

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

During the unlocking process, the lock tongue component 200 can be rotated counterclockwise from the fully locked position shown in Figure 1 under the action of the reset force (the reset force can be provided by the lock tongue component reset spring, such as a coil spring), thereby, the lock tongue component 200 can be rotated from the fully locked position shown in Figure 1 to the semi-locked position shown in Figure 3; further, when the pawl component 300 does not limit the position of the lock tongue component 200, the lock tongue component 200 can be rotated from the semi-locked position shown in Figure 3 to the unlocked position shown in Figure 5, completing the unlocking process.

Fig. 7 is a schematic structural diagram of a locking tongue component according to an embodiment of the present disclosure. Fig. 8 is a schematic structural diagram of Fig. 7 from another angle.

As shown in Figures 1 to 8, in the present disclosure, the lock tongue component 200 includes a U-shaped groove 210. The U-shaped groove 210 of the lock tongue component 200 is used to cooperate with components such as a lock buckle configured on the vehicle body to realize the locking function. In some embodiments of the present disclosure, when the lock tongue component 200 is in the fully locked position, the lock buckle can be stably maintained in the U-shaped groove 210; when the lock tongue component 200 is in the half-locked position, the lock buckle is still in the U-shaped groove 210; when the lock tongue component 200 is in the unlocked position, the lock buckle can be released by the lock tongue component 200, and the lock buckle can be disengaged from the U-shaped groove 210 of the lock tongue component 200.

In some preferred embodiments of the present disclosure, the lock tongue component 200 includes a lock tongue first feature 201 and a lock tongue second feature 202, and the lock tongue first feature 201 and the lock tongue second feature 202 are respectively located on both sides of the U-shaped groove 210; more specifically, the lock tongue first feature 201 is located on the first side (the lower side in FIG. 7 ) of the U-shaped groove 210, and correspondingly, the lock tongue second feature 202 is located on the second side (the upper side in FIG. 7 ) of the U-shaped groove 210. More preferably, the lock tongue first feature 201 and the lock tongue second feature 202 are both located near the opening of the U-shaped groove 210.

Fig. 9 is a schematic structural diagram of a pawl component according to an embodiment of the present disclosure. Fig. 10 is a schematic structural diagram of Fig. 9 from another angle.

In the present disclosure, as shown in FIGS. 1 to 5 and FIGS. 9 and 10, the pawl component 300 is rotatably disposed on the lock body 100, and the pawl component 300 can be in a first position, a second position, and a third position, wherein when the pawl component 300 is in the first position, the pawl component 300 can cooperate with the first feature 201 of the lock tongue and keep the lock tongue component 200 in a fully locked position; when the pawl component 300 is in the second position, the pawl component 300 can cooperate with the second feature 202 of the lock tongue and keep the lock tongue component 200 in a half-locked position; when the pawl component 300 is in the third position, the lock tongue component 200 can be in an unlocked position. In the present disclosure, the first position and the second position can 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 the movement from the first position to the second position, in the direction shown in FIG. 1 , the pawl component 300 may first rotate counterclockwise and release the bolt component 200 , and then rotate clockwise and move to the second position to keep the bolt component 200 at the second position.

In other words, in the present disclosure, through the structural design of the lock tongue component 200 (the first feature of the lock tongue and the second feature of the lock tongue are respectively located on both sides of the U-shaped groove), the size of the lock tongue 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 when it is in a fully locked state is improved.

Specifically, when the lock system of the present invention is in a fully locked state (as shown in FIG. 1 ), the force on the lock tongue component 200 is a simply supported beam structure, and compared with the cantilever beam structure of the conventional lock tongue component 200 in the fully locked position, the strength of the lock tongue component 200 is greatly improved, and accordingly, the lock tongue component 200 of the present invention will not be easily damaged by external forces. Moreover, under the premise of meeting the design requirements, since the force on the lock tongue component 200 of the present invention is a simply supported beam structure, its size can be reduced.

As shown in FIG. 1 , in the present disclosure, when the lock tongue component 200 is in the fully locked position, the lock tongue first feature 201 and the pawl component 300 are both located on the first side (lower side) of the U-shaped groove 210, and components such as a lock catch (not shown) are located between the rotation axis of the pawl component 300 and the rotation axis of the lock tongue component 200. Thus, the first arm of the lock tongue component 200 (the lower part of the U-shaped groove 210 in FIG. 1 , i.e., the right arm) and the pawl component 300 form a simply supported beam structure.

In some embodiments of the present disclosure, the contact surface between the pawl component 300 and the first feature 201 of the lock tongue (located on the first arm of the lock tongue component) is formed into a substantially flat surface (see FIG. 1 ), and accordingly, the first feature 201 of the lock tongue is also formed into a substantially flat surface (see FIG. 1 ). Preferably, a stop surface 205 is formed on the first arm of the lock tongue component 200, and when the lock tongue component 200 is in the fully locked position, the stop surface 205 can limit the further rotation of the pawl component 300, thereby preventing the pawl component 300 from being separated from the first position.

In the present disclosure, the pawl component 300 can be driven to rotate. In the state shown in FIG. 1 of the lock system, the pawl component 300 is in the first position; when the pawl component 300 is operated by an electric actuator or a manual actuator to disengage from the first position, the pawl component 300 will rotate in the counterclockwise direction shown in FIG. 1. In one case, the pawl component 300 can directly stop at the second position; in another case, after rotating in the counterclockwise direction, the pawl component 300 will rotate in the clockwise direction and rotate to the second position. Accordingly, when the pawl component 300 is in the second position, the lock tongue component 200 can rotate to the semi-locked position under the action of the reset force.

When the pawl component 300 is further driven in the second position, the pawl component 300 is disengaged from the second position, that is, it can rotate counterclockwise as shown in Figure 3 and rotate to the third position. Accordingly, when the pawl component 300 is in the third position, the bolt component 200 can rotate to the unlocking position under the action of the reset force, and the lock system is in the unlocking state.

During the locking process of the lock system, the pawl component 300 can be driven by a reset force such as provided by a pawl component reset spring (such as a coil spring) to disengage from the third position and move to the second position and the first position. Referring to FIG5 , the pawl component 300 can rotate clockwise under the action of the reset force (the lock tongue component 200 must first be disengaged from the unlocked position, as described below). During the locking process of the lock system, the lock tongue component 200 starts to move from the unlocked position and moves to the half-locked position and the fully locked position in sequence. During the movement of the lock tongue component 200, it can be driven by components such as the lock buckle described above to rotate clockwise, for example, starting from FIG5 . During the locking process of the lock system, the pawl component 300, under the action of the reset force, starts to move from the third position and moves to the second position and the first position in sequence (for example, rotating clockwise starting from FIG5 ).

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

When the lock system is in the fully locked state (see FIG. 1 ), the stop surface 205 of the bolt member 200 can limit the pawl member 300 in the first position from further resetting and prevent the pawl member 300 and the bolt member 200 from separating.

In a preferred embodiment of the present disclosure, the lock system of the present disclosure further includes a locking device 400 and an operating component 500, wherein the locking device 400 is rotatably disposed on the lock body 100 and is used to keep the pawl component 300 at the first position or the second position; the operating component 500 is rotatably disposed on the lock body 100 and is used to drive the locking device 400 to move. Preferably, the operating component 500 and the locking device 400 have the same rotation axis, and on the other hand, the rotation axis of the operating component 500 and the locking device 400 may also be different.

The present disclosure has redesigned the matching method and matching structure of the locking device 400 and the operating component 500, forming an important inventive content of the present disclosure, and configured the two to have the same rotation axis, in other words, to have the same rotation shaft, thereby facilitating the arrangement of the locking device 400 and the operating component 500 of the present disclosure, reducing the volume of the lock system of the present disclosure, so that the lock system of the present disclosure can be conveniently arranged on different vehicles, thereby improving the scope of use of the lock system of the present disclosure.

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

Fig. 11 is a schematic diagram of the structure of the operating component according to an embodiment of the present disclosure. Fig. 12 is a schematic diagram of the structure of Fig. 11 from another angle. Fig. 13 is a schematic diagram of the structure of the locking device according to an embodiment of the present disclosure. Fig. 14 is a schematic diagram of the structure of Fig. 13 from another angle.

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

1, the first end of the locking device 400 holds the first end of the pawl member 300 in a position engaged with the first feature 201 of the locking tongue. At this time, the pawl member 300 is in the first position and the locking device 400 is in the first locking position.

1 and 3 as well as 11 to 14 , when the operating component 500 is applied with external force and rotated counterclockwise (for example, the operating component 500 is applied with external force such as by an electric actuator via the first feature 501 of the operating portion), the operating component 500 rotates in a direction to release the lock of the pawl component 300 by the locking device 400, and drives the locking device 400 to rotate in a direction to release the lock of the pawl component 300 (counterclockwise in the figure), and the locking device 400 will leave the first locking position.

In a preferred embodiment of the present disclosure, a second operating feature 502 is provided on the operating part 500, and the second operating feature 502 is located on the first side (the left side in FIG. 1 ) of the locking device 400. When the operating part 500 rotates counterclockwise (refer to FIG. 1 ), the locking device 400 (via the second end of the locking device 400) is driven to rotate counterclockwise via the second operating feature 502, and the locking device 400 releases the pawl part 300.

When the pawl component 300 is driven to rotate counterclockwise, it can move from the first position shown in Figure 1 to the second position shown in Figure 3. In a preferred embodiment, the pawl component 300 can be driven and rotated by the operating component 500, that is, when the operating component 500 drives the locking device 400 to rotate and releases the pawl component 300, the operating component 500 cooperates with the pawl component 300 to drive the pawl component 300 to rotate.

In one embodiment, when the first position and the second position of the pawl component 300 are the same position, the unlocking process of the locking device may not pass through the second position, that is, the operating component 500 can directly drive the pawl component 300 to the third position, and accordingly, the locking device can also be directly rotated from the fully locked position to the open position.

Correspondingly, when the operating component 500 rotates counterclockwise and then clockwise, the operating component 500 can release the pawl component 300. Correspondingly, when the lock tongue component 200 leaves the fully locked position, the pawl component 300 will be tightly attached to the lock tongue component 200 under the action of the reset force, and then move to the second position shown in Figure 3, thereby keeping the lock tongue component 200 in the semi-locked position.

When the lock system is in the semi-locked state shown in Figure 3, when the operating component 500 is driven again and rotated counterclockwise again, it can drive the pawl component 300 to move from the second position shown in Figure 3 to the third position shown in Figure 5, and the lock tongue component 200 moves to the unlocked position shown in Figure 5 under the action of the reset force, thereby realizing the 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 third feature 503 of the operating portion, so that the pawl member 300 leaves the first position.

In a preferred embodiment of the present disclosure, the operating part 500 is provided with a fourth operating feature 504. When the lock system is in a semi-locked state (the bolt member 200 is in a 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, so that the pawl member 300 is stably held in the second position. The fourth operating feature 504 holds the second arm of the bolt member 200 (blocking the bolt member 200 from continuing to rotate clockwise, as shown in FIG. 3), so that the bolt member 200 is stably held in the semi-locked position. Accordingly, the third bolt feature 203 (located at the end of the second arm of the bolt member 200, and arranged away from the second bolt feature 202) cooperates with the fourth operating feature 504, so that the bolt member 200 is held in the semi-locked position by the fourth operating feature 504 and the first end of the pawl member 300.

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

When the lock system is in the semi-locked state shown in Figure 3, when the first feature 501 of the operating part is driven, the operating part 500 rotates counterclockwise, the fourth feature 504 of the operating part will release the hold on the third feature 203 of the lock tongue, and due to being driven by the second feature 502 of the operating part, the locking device 400 follows the operating part 500 to rotate counterclockwise, and the first end of the locking device 400 will release the hold on the first end of the pawl part 300. The pawl part 300 moves to the third position under the drive of the third feature 503 of the operating part, and releases the hold on the lock tongue part 200. The lock tongue part 200 moves to the unlocked position under the action of the reset force, thereby realizing the unlocking of the lock system, and the lock system reaches the unlocked state, as shown in Figure 5.

During the unlocking process of the lock system, when the pawl component 300 is located in the second position (refer to Figure 3), if the force applied to the first feature 501 of the operating part disappears at this time, the operating part 500 will have a tendency to rotate clockwise under the action of the operating part reset spring (not shown, such as a coil spring), and the fourth feature 504 of the operating part will abut against the third feature 203 of the lock tongue, thereby jointly with the first end of the pawl component 300 to keep the lock tongue component 200 in the semi-locked position. At this time, the first end of the locking device 400 and the third feature 503 of the operating part jointly keep the pawl component 300 in the second position.

In the state shown in FIG. 3 (the lock system is in a semi-locked state), when the operating component 500 is subjected to an external force and rotated counterclockwise, the second feature 502 of the operating part drives the locking device 400 (drives the second end of the locking device 400), the locking device 400 rotates counterclockwise, and the locking device 400 will leave the second locking position (the position of the locking device in FIG. 3), the pawl component 300 is released, and the pawl component 300 is driven by the third feature 503 of the operating part and rotates counterclockwise, moving from the second position to the third position. Under the action of the reset force, the bolt component 200 moves from the semi-locked position to the unlocked position, and the lock system moves from the state shown in FIG. 3 to the state shown in FIG. 5, the bolt component 200 is in the unlocked position, and the lock catch in the U-shaped groove 210 will be released.

5 and 7 , in some embodiments of the present disclosure, the third feature 203 of the lock tongue and the second feature 202 of the lock tongue are both located at the end of the second arm of the lock tongue component 200, and when the pawl component 300 cooperates with (is in contact with) the third feature 203 of the lock tongue, the lock tongue component 200 remains in the unlocked position.

In a preferred embodiment of the present disclosure, referring to FIGS. 1 to 5 of the present disclosure, the operating portion first feature 501 described above in the present disclosure is configured on the operating portion third feature 503 described above in the present disclosure.

In some embodiments of the present disclosure, the third feature 503 of the operating part is in the form of an operating handle, and the first feature 501 of the operating part is in the form of a through hole. Inspired by the technical solution of the present disclosure, adjustments made by those skilled in the art to the structure or shape of the third feature 503 of the operating part and the first feature 501 of the operating part all fall within the protection scope of the present disclosure.

In a preferred embodiment of the present disclosure, the line between the third feature 503 of the operating portion and the fourth feature 504 of the operating portion passes through the rotation axis (rotation axis, i.e., the third axis) of the operating component 500, or is adjacent to the rotation axis of the operating component 500. With reference to FIGS. 1 to 5 , the rotation axis of the operating component 500 is located or approximately located between the third feature 503 of the operating portion and the fourth feature 504 of the operating portion.

In the present disclosure, when the pawl component 300 leaves the first position or the second position, it can leave the movement path range of the lock tongue component, so that the lock tongue component can rotate in the unlocking direction.

The locking process of the lock system of the present disclosure is described below with reference to FIGS. 1 to 5 .

During the locking process of the lock system, the lock tongue component 200 is driven by components such as a lock buckle, and moves from the unlocked position to the semi-locked position and the fully locked position. When the pawl component 300 is out of contact with the end of the second arm of the lock tongue component 200, the pawl component 300 can move from the third position (the position of the pawl component 300 in Figure 5) to the second position and the first position under the action of the reset force (the pawl component reset spring); the locking device 400 rotates clockwise under the action of the reset force (for example, the locking device reset spring, which can be a coil spring), that is, rotates in the direction of locking the pawl component 300. When the locking device 400 moves to the second locked position, the first end of the locking device 400 locks the pawl component 300 in the second position, as shown in Figure 3. During the process of the lock system moving from the unlocked state to the semi-locked state, the operating component 500 rotates clockwise under the action of the reset force (for example, provided by the operating component reset spring), and the fourth feature 504 of the operating part will abut against the third feature 203 of the lock tongue.

In some embodiments of the present disclosure, at least part of the outer surface of the third arm (preferably, the third arm is formed by the transverse extension of the second arm) of the bolt member 200 is formed as a guide surface 204. When the bolt member 200 moves from the unlocked position to the semi-locked position, the fourth feature 504 of the operating portion moves in a manner of being close to the guide surface 204 of the bolt member 200. More preferably, the guide surface is configured so that when the pawl member 300 is located at the second position, the locking device 400 moves to the second position.

In a preferred embodiment, the locking device 400 can rotate relative to the operating member 500, and the locking device 400 can be in close contact with the second feature 502 of the operating portion under the action of the reset force provided by the reset spring, etc.; during the locking process, the lock tongue member 200 can drive the pawl member 300 to leave the third position and further rotate clockwise, at which time, the pawl member 300 can push the locking device 400 to rotate counterclockwise and generate relative movement with the operating member 500, and at this time, the locking device 400 will not move to the second locking position. Then, when the lock tongue member 200 moves to the semi-locked position, the pawl member 300 rotates counterclockwise under the action of the reset force and moves to the second position, and accordingly, the locking device 400 can rotate clockwise under the action of the reset force and move to a position in close contact with the second feature 502 of the operating portion, and at this time, the locking device 400 is in the second locking position.

In the present disclosure, the locking device 400 can also rotate clockwise together with the operating component 500, and the locking device 400 can keep the pawl component 300 in the second position, and accordingly, the locking tongue component 200 is kept in the semi-locked position, as shown in FIG. 3 .

Furthermore, taking the state shown in FIG3 as a starting point, during the locking process of the lock system, the lock tongue component 200 is further driven by, for example, a lock buckle. During the process of the lock tongue component 200 moving from the semi-locked position to the fully locked position, the lock tongue component 200 first directly drives the operating component 500 (the lock tongue component 200 drives the operating component 500 via the fourth feature 504 of the operating part) to rotate counterclockwise, and the second feature 502 of the operating part drives the second end of the locking device 400, so that the locking device 400 and the operating component 500 rotate counterclockwise synchronously, and the locking device 400 disengages from the second locking position, releasing the lock on the pawl component 300, and the pawl component 300 is driven by the third feature 503 of the operating part to rotate counterclockwise, and the first end of the pawl component 300 disengages from the second feature 202 of the lock tongue, so that the lock tongue component 200 can continue to move toward the fully locked position under the drive of the lock buckle and other components.

After the end of the first arm of the locking tongue component 200 is out of contact with the side of the first end of the pawl component 300, the pawl component 300 continues to rotate clockwise under the action of the reset force (which can be provided by the pawl component reset spring) and moves to the first position, as shown in FIG1. During this process, the operating component 500 and the locking device 400 rotate clockwise under the action of the reset force they are respectively subjected to, and the locking device 400 moves to the first locking position (the position shown in FIG1), locking the pawl component 300 in the first position. At this time, the fourth feature 504 of the operating part moves to a position opposite to the U-shaped groove 210. Preferably, at this time, the fourth feature 504 of the operating part is located at the opening of the U-shaped groove 210, as shown in FIG1.

In the present disclosure, when the lock tongue component 200 moves from the semi-locked position to the fully locked position, the pawl component 300 first moves in the direction away from the first position (rotates counterclockwise), and then moves in the direction close to the first position (rotates clockwise), so that the lock tongue component 200 is first released from the semi-locked position and then locked again in the fully locked position.

FIG. 15 is a schematic diagram of the internal structure of a lock system according to an embodiment of the present disclosure.

As shown in FIG. 15 , the operating component 500 of the present disclosure can be driven to rotate by the unlocking motor 101, thereby realizing the unlocking of the lock system. Specifically, the unlocking motor 101 can be arranged on the lock body 100, and can be in transmission connection with the unlocking gear 102. In a specific embodiment, the unlocking gear 102 is rotatably arranged 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 component 500, thereby enabling the lock system of the present disclosure to be conveniently arranged in the door and other components of a motor vehicle.

In a preferred embodiment, the output shaft of the unlocking motor 101 is formed as a worm, and the worm can mesh with the teeth on the outer periphery of the unlocking gear 102. In this case, the unlocking gear 102 can also be called an unlocking worm wheel. In the present disclosure, the worm can be a three-head worm, so that the worm and the unlocking gear 102 will not be self-locking. That is to say, 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 of the unlocking gear 102 in the axial direction, and the cam surface of the cam 102A is the outer peripheral surface of the cam 102A. When the unlocking gear 102 is driven to rotate, the outer peripheral surface of the cam 102A can drive the unlocking rod 103 to rotate, and the unlocking rod 103 is in contact with the operating component 500 to unlock the lock system.

In a specific embodiment, the unlocking lever 103 is rotatably disposed on the lock body 100, and the unlocking lever 103 has a B-th axis, and the A-th axis is disposed parallel to the B-th axis and spaced a certain distance apart.

In the present disclosure, the unlocking rod portion 103 may include an unlocking rod first feature 103A, wherein the unlocking rod first feature 103A may be formed as an arm portion of the unlocking rod portion 103, so that when the unlocking rod first feature 103A contacts the surface of the cam 102A and is driven by the cam 102A, the unlocking rod portion 103 can be applied an unlocking torque by the cam 102A.

Moreover, the unlocking lever portion 103 also includes an unlocking lever second feature 103B. Preferably, the unlocking lever second feature 103B is also formed as an arm portion of the unlocking lever portion 103, and the unlocking lever second feature 103B can contact the operating part 500 and drive the operating part 500 to rotate in the unlocking direction.

The lock system of the present invention can also be manually unlocked. Specifically, the lock system of the present invention also includes an inner opening rod portion 104, which is rotatably arranged on the lock body 100, and correspondingly, the inner opening rod portion 104 has a C-th axis, wherein the C-th axis, the A-th axis and the B-th axis are all arranged in parallel and spaced apart by a preset distance.

More specifically, the inner opening rod portion 104 has an inner opening rod first feature 104A, and the inner opening rod first feature 104A can be formed as an arm portion of the inner opening rod portion 104, so that an inner opening wire can be set on the inner opening rod first feature 104A, and when an external force is applied to the inner opening rod portion through the inner opening wire, the inner opening rod portion 104 can be rotated. For example, when the lock system is opened, the inner opening rod portion 104 can rotate clockwise in the direction shown in FIG. 4. In addition, when the external force applied by the inner opening wire lock is removed, the inner opening rod portion 104 can rotate counterclockwise under the action of the restoring force of a reset element such as a coil spring, and be maintained at a preset initial position.

The inner opening tie rod portion 104 further includes an inner opening tie rod second feature 104B, and the inner opening tie rod second feature 104B is also formed as an arm portion of the inner opening tie rod portion 104, so that the inner opening tie rod portion 104 can drive the unlocking rod portion 103 to rotate through the cooperation of the inner opening tie rod second feature 104B and the unlocking rod portion 103. More preferably, the unlocking rod portion 103 includes an unlocking rod third feature 103C, and accordingly, the inner opening tie rod second feature 104B can cooperate with the unlocking rod third feature 103C.

In one embodiment, as shown in FIG. 15 , when the unlocking gear 102 rotates clockwise, it can drive the unlocking rod 103 to rotate counterclockwise and drive the operating component 500 to rotate in the unlocking direction; and, when the inner opening pull rod 104 rotates clockwise, it can also drive the unlocking rod 103 to rotate counterclockwise and unlock the lock system.

FIG. 16 is another schematic diagram of the internal structure of a lock system according to an embodiment of the present disclosure.

As shown in Figures 15 and 16, the lock system of the present invention also includes a super lock push rod portion 105, which is used to push the unlocking rod portion 103 to rotate to a preset position. At this position, when the inner opening pull rod portion 104 is driven and rotated, it cannot drive the unlocking rod portion 103 to rotate, that is, the inner opening pull rod portion 104 does not cooperate with the unlocking rod portion 103.

Specifically, in the direction shown in Figure 15, the super lock push rod portion 105 can be driven and moved to the left, and can be in the position shown in Figure 16, and the super lock push rod portion 105 can cooperate with the second feature 103B of the unlocking rod, and push the unlocking rod portion 103 to rotate clockwise. At this time, the third feature 103C of the unlocking rod will be disengaged from the motion envelope surface of the second feature 104B of the inner opening pull rod. Accordingly, even if the inner opening pull rod portion 104 is pulled, it will not drive the unlocking rod portion 103 to rotate, and accordingly the lock system will not be unlocked.

In other words, the super lock push rod portion 105 of the present invention can prevent the lock system from being opened by the inner opening pull rod portion 104, that is, when the super lock push rod portion 105 is in working state, the lock system cannot be opened by the inner opening pull rod portion 104, thereby making the lock system safer.

On the other hand, when the super lock push rod 105 pushes the unlocking rod 103 to rotate, the super lock push rod 105 can be limited to a position, so that the unlocking rod 103 cannot be driven to rotate, that is, at this time, even if the unlocking motor 101 is powered, the unlocking motor 101 cannot push the unlocking rod 103 to rotate, and correspondingly, unlocking cannot be achieved. In other words, at this time, only by first removing the restriction of the super lock push rod 105 to the unlocking rod 103, the lock system can be opened. On the other hand, when the unlocking motor 101 is powered on and drives the unlocking rod 103 to rotate, the unlocking rod 103 can push the super lock push rod 105 to move, and at this time, the super lock push rod 105 can move to the right, and correspondingly, the super lock push rod 105 can only realize the function of preventing manual unlocking, and it cannot prevent electric unlocking. In other words, no matter where the super lock push rod 105 is, the electric unlocking function of the lock system is always effective.

FIG. 17 is another schematic diagram of the internal structure of a lock system according to an embodiment of the present disclosure.

As shown in Figure 17, the lock system also includes a super lock push rod motor 121 and a super lock push rod gear 122, wherein the super lock push rod motor 121 can be powered on and rotated, and a worm is provided on the output shaft of the super lock push rod motor 121, or in other words, the output shaft of the super lock push rod motor 121 is formed as a worm, and the worm can mesh with the teeth of the outer periphery of the super lock push rod gear 122, and now the super lock push rod gear 122 can also be referred to as a super lock push rod worm gear. In the present disclosure, the worm can adopt a single-head worm or a multi-head worm, which will not be repeated one by one.

FIG. 18 is a schematic structural diagram of a super lock push rod gear according to an embodiment of the present disclosure.

As shown in Figure 18, the super lock push rod gear 122 is formed as a fan-shaped gear, and accordingly, the super lock push rod gear 122 has a first end and a second end in the circumferential direction, wherein an outer extension portion 122A is provided at the first end in the circumferential direction of the super lock push rod gear 122, and a long strip hole is opened on the outer extension portion 122A, and the length direction of the long strip hole is the radial direction of the super lock push rod gear 122, wherein one end of the super lock push rod portion 105 is used to cooperate with the unlocking rod portion 103, and the other end of the super lock push rod portion 105 includes a columnar portion, which is slidably arranged in the long strip groove, so that when the super lock push rod gear 122 rotates, the super lock push rod portion 105 can be moved left and right.

In the present disclosure, a first elongated groove is provided in the middle part of the super lock push rod part 105, and the length direction of the first elongated groove of the super lock push rod part 105 is the length direction of the super lock push rod part 105, and a first guide column can be provided on the lock body 100, and the first guide column can move in the first elongated groove; in addition, a second elongated groove is also provided at the other end of the super lock push rod part 105, and the length directions of the first elongated groove and the second elongated groove are parallel, and a second guide column can be provided on the lock body 100, and the second guide column can move in the second elongated groove; thereby, through the cooperation of the first guide column and the first elongated groove, and through the cooperation of the second guide column and the second elongated groove, the super lock push rod part 105 can be translated along a preset direction.

At this time, when the super lock push rod motor 121 rotates in the forward or reverse direction, the super lock push rod portion 105 can be driven to move left or right. On the other hand, the worm of the present disclosure and the super lock push rod gear 122 will not self-lock, 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 opposite working process, when the super lock push rod gear 122 is driven to rotate, it can also drive the worm to rotate.

In the present disclosure, a limiting portion 122B is also formed on an axial surface of the first end of the super lock push rod gear 122. The limiting portion 122B can cooperate with a limiting structure provided on the lock body 100 to limit the rotation angle of the super lock push rod gear 122 and prevent the super lock push rod gear 122 from being disconnected from the transmission connection relationship with the worm gear.

Referring again to FIG. 16 , the lock system of the present disclosure further includes a lock core rod portion 123 , wherein the lock core rod portion 123 has a D-th axis, wherein the D-th axis can be arranged parallel to the first axis, thereby enabling the lock core rod portion 123 to rotate when the user unlocks the lock by means of a key or other components.

Specifically, the lock core rod portion 123 of the present disclosure includes a lock core rod first feature 123A, which is formed as an arm portion of the lock core rod portion 123. Accordingly, the lock core rod first feature 123A can be connected to components such as pull wires and driven to rotate by components such as pull wires.

Moreover, the lock core pull rod portion 123 also includes a lock core pull rod second feature 123B, and the lock core pull rod second feature 123B is formed as an arm portion of the lock core pull rod portion 123, and the lock core pull rod second feature 123B is located in the area between the first end and the second end of the super lock push rod gear 122, so that when the lock core pull rod portion 123 is driven to rotate, it can push the super lock push rod gear 122 to rotate.

Specifically, in the direction shown in Figure 16, when the lock core pull rod portion 123 is operated to rotate counterclockwise, the lock core pull rod second feature 123B can drive the second end of the super lock push rod gear 122 and enable the super lock push rod gear 122 to rotate clockwise; further, when the super lock push rod gear 122 rotates clockwise, it can drive the super lock push rod portion 105 to move to the right, thereby releasing the unlocking rod portion 103, whereby the lock system is in a state that can be opened, and accordingly, the lock system can be unlocked by the external opening pull rod portion 133 described below; of course, at this time, the system can also be unlocked by the above-mentioned internal opening pull rod portion 104.

Fig. 19 is a schematic structural diagram from another angle of Fig. 16. Fig. 20 is a schematic structural diagram of a lock system according to an embodiment of the present disclosure.

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

At least a portion of the emergency unlocking portion 131 can pass through the through hole of the lock body 100 , and the emergency unlocking portion 131 can be driven to rotate by a screwdriver or other components.

In a specific embodiment, the emergency unlocking portion 131 is formed as a substantially fan-shaped component, and a circular arc groove 131A is formed on the emergency unlocking portion 131 , and the center of the circular arc groove 131A is located on the E-axis.

FIG. 21 is a schematic structural diagram of an outwardly opening transition rod according to an embodiment of the present disclosure.

As shown in FIG. 21 , the lock system of the present disclosure further includes an outward-opening transition rod 132, one end of which is provided with a cylindrical portion 132A, and the cylindrical portion 132A can be slidably and rotatably provided in the arc-shaped groove 131A, and the arc-shaped groove 131A includes a first end and a second end, wherein the first end of the arc-shaped groove 131A is an end away from the other end of the outward-opening transition rod 132, and correspondingly, the second end of the arc-shaped groove 131A is an end close to the other end of the outward-opening transition rod 132. In other words, compared with the first end of the arc-shaped groove 131A, the second end of the arc-shaped groove 131A is closer to the other end of the outward-opening transition rod 132.

The cylindrical portion 132A is provided with a spring accommodating portion 132B, and a groove may be formed on the spring accommodating portion 132B. In this case, one end of a spring (e.g., a coil spring) may be accommodated in the groove, and the other end of the spring may be arranged on the emergency unlocking portion 131, so that the cylindrical portion 132A may be maintained at the first end of the arc-shaped groove 131A through the reset force provided by the spring.

In addition, the outward-opening transition rod portion 132 also includes an outward-opening transition rod first feature 132C, and the outward-opening transition rod first feature 132C can be formed as a limiting structure. Accordingly, the super lock push rod portion 105 includes a protruding feature. When the super lock push rod portion 105 is in the working position, it can limit the position of the outward-opening transition rod portion 132 and make it impossible for the outward-opening pull rod portion 133 to drive the operating component 500 to rotate through the outward-opening transition rod portion 132.

FIG. 23 is another schematic diagram of the internal structure of a lock system according to an embodiment of the present disclosure.

In one embodiment of the present disclosure, as shown in FIG. 23 , the operating component 500 has an end portion along the circumferential direction, and the other end of the outward-opening transition rod portion 132 can selectively cooperate with the operating component 500 through the rotation of the emergency unlocking portion 131 .

In addition, as shown in FIG. 23 , the lock system of the present disclosure further includes an outward opening rod portion 133, wherein the outward opening rod portion 133 has a first axis F, that is, the outward opening rod portion 133 can be driven to rotate. In a specific embodiment, the outward opening rod portion 133 can be driven by an outer door handle of the vehicle to achieve rotation. In a preferred embodiment, the first axis F is the same as (coincides with) the third axis.

At the same time, the outer opening tie rod portion 133 is formed with a notch, and at least part of the other end of the outer opening transition rod portion 132 is located in the notch of the outer opening tie rod portion 133, and the other end of the outer opening transition rod portion 132 can slide in the notch. In other words, the running stroke of the outer opening transition rod portion 132 is within the depth range of the notch, and no matter where the outer opening transition rod portion 132 is located, its other end will not be separated from the notch.

In the state shown in Figure 16, the other end of the outward-opening transition rod portion 132 is located in the groove of the outward-opening pull rod portion 133 and does not cooperate with the end of the operating component 500. At this time, when the outward-opening pull rod portion 133 is driven to rotate clockwise, it will not drive the operating component 500 to rotate, and accordingly, the locking system will not be unlocked.

When the emergency unlocking portion 131 is driven to rotate clockwise, it can pull the outward-opening transition rod portion 132 to move to the right, so that the other end of the outward-opening transition rod portion 132 slides in the slot and approaches the bottom wall of the slot, the other end of the outward-opening transition rod portion 132 can cooperate with the end of the operating component 500. At this time, when the outward-opening pull rod portion 133 is driven to rotate clockwise, it can drive the operating component 500 to rotate, and accordingly, the lock system can be unlocked.

In the present disclosure, the lock system further includes an intermediate transition rod 134, and the intermediate transition rod 134 has a Gth axis, that is, the intermediate transition rod 134 can rotate relative to the lock body 100, wherein the Gth axis can be parallel to the first axis.

The intermediate transition rod portion 134 is used to drive the emergency unlocking portion 131 to rotate. Specifically, the intermediate transition rod portion 134 includes an intermediate transition rod first feature 134A, and the intermediate transition rod first feature 134A can be formed as a wall portion of the intermediate transition rod portion 134, and a slide groove 134B with an opening is formed on the intermediate transition rod first feature 134A, and the extension direction of the slide groove 134B is toward the Gth axis of the intermediate transition rod portion 134, that is, the slide groove 134B extends along the radial direction of the intermediate transition rod portion 134, and the outer peripheral surface of the emergency unlocking portion 131 is provided with a slide column 131B, and the slide column 131B can be slidably arranged in the slide groove 134B, thereby, when the intermediate transition rod 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 groove 134C, and the intermediate groove 134C includes a first side wall and a second side wall along the circumference of the intermediate transition rod portion 134, wherein the lock core pull rod portion 123 includes a lock core pull rod third feature 123C, and the lock core pull rod third feature 123C is formed as a wall portion of the lock core pull rod portion 123, and the lock core pull rod third feature 123C is located in the intermediate groove 134C, when the lock core pull rod portion 123 rotates, it can contact the above-mentioned first side wall or the second side wall, thereby pushing the intermediate transition rod portion 134 to rotate in different directions.

Specifically, taking the direction shown in Figure 16 as an example, when the lock core pull rod portion 123 is operated to rotate counterclockwise, the third feature 123C of the lock core pull rod can contact the first side wall of the intermediate transition rod portion 134 and drive the intermediate transition rod portion 134 to rotate clockwise, and then the intermediate transition rod portion 134 will drive the emergency unlocking portion 131 to rotate counterclockwise, thereby causing the outward opening transition rod portion 132 to move, and at this time the lock system can be opened by the outward opening pull rod portion 133.

In the present disclosure, the lock core pull rod 123 can rotate clockwise under the action of a reset element such as a torsion spring, and accordingly, it can drive the emergency unlocking portion 131 to rotate clockwise. Moreover, the emergency unlocking portion 131 can also rotate counterclockwise under the action of a reset element such as a torsion spring.

Fig. 24 is a schematic diagram of the structure of an emergency unlocking part of a lock system according to an embodiment of the present disclosure. Fig. 25 is a schematic diagram of the structure of a safety link part of a lock system according to an embodiment of the present disclosure.

As shown in Figures 24 and 25, the lock system of the present disclosure further includes a safety link portion 141, which 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, for example, the lock body 100 and move along a preset direction, and when the safety link portion 141 moves, it can push the emergency unlocking portion 131 to rotate.

Specifically, as shown in FIG24 , the emergency unlocking portion 131 includes a sliding block 131C, which can protrude upward from the plane where the emergency unlocking portion 131 is located, and the lower portion of the sliding block 131C is cylindrical, and the upper portion is a hemispherical body, and the axis of the sliding block 131C can be parallel to the rotation axis of the emergency unlocking portion 131. In a preferred embodiment, the surface of the sliding block 131C close to the safety link portion 141 can be a plane.

One end of the safety link portion 141 is formed with a receiving groove 141A, and the sliding block 131C can slide in the receiving groove 141A, so that when the safety link portion 141 moves in a direction perpendicular to the rotation axis of the emergency unlocking portion 131, it can apply a thrust to the sliding block 131C, thereby causing the emergency unlocking portion 131 to rotate.

Furthermore, by providing the accommodating groove 141A, when the emergency unlocking portion 131 rotates, the sliding block 131C can be located at different positions of the accommodating groove 141A, so that the sliding block 131C will not interfere with the safety link portion 141 .

In one embodiment, the safety link portion 141 can be driven to rotate by the driving claw portion 142. Specifically, a driving block 102B is formed on the unlocking gear 102, 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 respectively located at two ends of the unlocking gear 102 in the axial direction.

That is, the driving claw portion 142 can be driven and rotated by the unlocking gear 102 , and accordingly, the driving claw portion 142 has an Hth axis, which can be arranged in parallel with the rotation axis (ie, the Ath axis) of the unlocking gear 102 .

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

Correspondingly, in the direction shown in Figure 15, when the unlocking gear 102 rotates in the second direction, the unlocking gear 102 rotates counterclockwise. In the direction shown in Figure 27, the unlocking gear 102 rotates clockwise.

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

Specifically, as shown in FIG27, when the unlocking gear 102 rotates clockwise, the driving block 102B can cooperate with the first driving member 142A and apply a thrust to the first driving member 142A, thereby causing the driving claw to rotate counterclockwise. In the opposite working process, when the unlocking gear 102 is driven to rotate counterclockwise in the direction shown in FIG27, that is, rotate along the first rotation direction, the driving block 102B can cooperate with the second driving member 142B and apply a force to the second driving member 142B, thereby causing the driving claw to rotate clockwise.

As shown in FIG28 , a guide groove 141B is formed at the other end of the safety link portion 141. In the present disclosure, the length direction of the guide groove 141B can be perpendicular to the movement direction of the safety link portion 141, or in other words, the length direction of the guide groove 141B can be perpendicular to the length direction of the safety link portion 141. At this time, a cylindrical protrusion 142C is formed on the driving claw portion 142, and the cylindrical protrusion 142C can slide in the guide groove 141B of the safety link portion 141, so that when the driving claw portion 142 rotates, the safety link portion 141 can be driven to translate.

Specifically, in the direction shown in FIG. 27 , when the driving claw 142 rotates counterclockwise, it can drive the safety link 141 to move to the left; on the other hand, when the driving claw 142 rotates clockwise, it can drive the safety link 141 to move to the right. Further, when the safety link 141 moves, it can drive the emergency unlocking part 131 to rotate. The driving process of the safety link 141 on the emergency unlocking part 131 has been described in detail above, and will not be repeated here.

In a preferred embodiment, the first driving member 142A and the second driving member 142B can have substantially the same structure, and hooks are formed at the ends of the first driving member 142A and the second driving member 142B, thereby making the size of the opening of the working space smaller than the internal size of the working space, so that when the unlocking gear 102 drives the driving claw portion 142 to move, the driving claw portion 142 can have a larger movement stroke.

In the present disclosure, as shown in Figure 28, the safety link portion 141 also includes a safety link first feature 141C, and the safety link first feature 141C can be formed into a cylindrical shape. Moreover, the inner opening pull rod portion 104 also includes an inner opening pull rod third feature 104C, and the inner opening pull rod third feature 104C can be formed as a wall portion of the inner opening pull rod portion 104, and the safety link portion 141 can be pushed to move through the inner opening pull rod third feature 104C, thereby enabling the outer opening pull rod portion 133 to be used when unlocking.

Referring again to FIG. 26 and FIG. 27 , the lock system of the present disclosure further includes a stopper 143, which can be guided by the lock body 100 and move in a preset direction. In a preferred embodiment, the stopper 143 can be driven by the driving claw 142 and move in a preset direction. Specifically, the driving claw 142 includes a shift fork 142D, which can cooperate with the stopper 143 and push the stopper 143 to a position where at least part of the stopper 143 interferes with the unlocking gear 102, and thus can be used to limit the rotation of the unlocking gear 102. For example, the stopper 143 can cooperate with the cam 102A of the unlocking gear 102, thereby blocking the excessive movement of the unlocking gear in the second rotation direction through the stopper 143, that is, through the stopper 143, the unlocking gear 102 cannot rotate one circle in the second rotation direction.

In the lock system disclosed in the present invention, the half-locking pawl is not required to limit the lock tongue component, which simplifies the structure of the lock system and reduces the cost of the lock system. In addition, the lock system of the present invention has better reliability.

The lock system of the present invention also includes a child safety link portion 151, which is configured to be rotatable relative to the lock body and has a working position and a non-working position, wherein when the child safety link portion 151 is located in the working position, it can prevent the unlocking rod portion 131 from rotating in the unlocking direction, and correspondingly, when the child safety link portion 151 is located in the non-working position, it can allow the unlocking rod portion 131 to rotate in the unlocking direction, at which time the system can be unlocked.

More specifically, as shown in Figure 25, the child safety link portion 151 includes a limiting component 151A, and the limiting component 151A can be formed into a cylindrical shape, and the unlocking rod portion 103 also includes a fourth feature 103D of the unlocking rod; when the child safety link portion 151 is in the working position, the limiting component 151A can block the fourth feature 103D of the unlocking rod, thereby preventing the unlocking rod portion 103 from rotating in the unlocking direction.

Figure 30 is a schematic diagram of the structure of the safety link portion of the lock system according to another embodiment of the present disclosure. Figure 31 is a schematic diagram of the structure of the safety link portion of the lock system according to another embodiment of the present disclosure at another angle. Figure 32 is a parts diagram of the safety link portion of the lock system according to another embodiment of the present disclosure.

The present disclosure also provides another implementation form of the safety link portion 141. Specifically, as shown in FIG. 32,

One end of the safety link portion 141 is formed with a receiving groove 141A, and the sliding block 131C can slide in the receiving groove 141A, so that when the safety link portion 141 moves in a direction perpendicular to the rotation axis of the emergency unlocking portion 131, it can apply a thrust to the sliding block 131C, thereby causing the emergency unlocking portion 131 to rotate.

Furthermore, by providing the accommodating groove 141A, when the emergency unlocking portion 131 rotates, the sliding block 131C can be located at different positions of the accommodating groove 141A, so that the sliding block 131C will not interfere with the safety link portion 141 .

The safety link portion 141 also includes a safety link first feature 141C, wherein the safety link first feature 141C can be located at the other end of the safety link portion 141, and the safety link first feature 141C can be formed into a cylindrical shape, and the inner opening pull rod portion 104 also includes an inner opening pull rod third feature 104C, and the inner opening pull rod third feature 104C can be formed as a wall portion of the inner opening pull rod portion 104, and the safety link portion 141 can be pushed to move through the inner opening pull rod third feature 104C, thereby enabling the outer opening pull rod portion 133 to be used when unlocking.

Different from the above-mentioned implementation, in this implementation, the safety link portion 141 is not driven by the driving claw portion 142, that is, the lock system of this implementation does not include the driving claw portion 142, and accordingly, the unlocking gear 102 does not include components such as the driving block 102B.

A rack structure 141D is formed on the surface of the middle part of the safety link part 141 close to the unlocking gear 102, so that the safety link part 141 is driven to move through the meshing of the rack structure with the teeth on the peripheral surface of the unlocking gear 102. Specifically, the safety link part 141 of the present disclosure includes a plurality of columnar structures, and the safety link part 141 can move in a preset direction through the cooperation of the columnar structures with the guide grooves provided on 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 along the first rotation direction (unlocking direction), in the direction shown in Figure 30, the unlocking gear 102 will rotate clockwise, and accordingly, the safety link portion 141 will be driven and move to the left. At this time, the emergency unlocking portion 131 will rotate and push the outward transition rod portion 132 to the non-working position. At this time, the locking device cannot be unlocked by the outward pull rod portion 133, and can only be unlocked using the inward unlocking pull rod or the unlocking gear 102.

On the other hand, when the unlocking gear 102 rotates in the second rotation direction, that is, the counterclockwise direction shown in FIG. 30, and the safety link portion 141 moves to the right, the emergency unlocking portion 131 rotates and pushes the outer transition rod portion 132 to the working position. At this time, the lock device can be unlocked by the outer pull rod portion 133, thereby realizing the keyless entry and other functions of the vehicle. That is to say, when the lock system of the present disclosure is in use, it can be unlocked by the lock core pull rod portion with a key, or by triggering a trigger switch or other structure set on the door to energize the unlocking motor, and then push the outer transition rod portion 132 to the working position.

In one embodiment of the present disclosure, a part can be maintained at a preset position or reset to a preset position by a structure such as a return spring or a damper. These structures can be implemented using structures in the prior art and will not be described in detail in the present disclosure.

In the present disclosure, the lock body 100 may include a mounting base plate. In actual use, the lock system may be installed on a vehicle by mounting the mounting base plate on the vehicle. Preferably, the unlocking motor 101 is arranged on a wall perpendicular to the mounting base plate, and the super lock push rod motor 121 is arranged on the mounting base plate or on a surface parallel to the mounting base plate. Accordingly, the connector 600 is arranged at a position above the lock tongue component 200 and is arranged perpendicular to the mounting base plate, so that the distance between the connector 600 and the two motors can be minimized, saving the size of the circuit.
