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.

Fig. 1 is a schematic structural view of a lock system according to one embodiment of the present disclosure. Fig. 2 is another angular structural schematic diagram of a lock system according to one embodiment of the present disclosure.

As shown in fig. 1 and 2, the present disclosure provides a lock system, and in particular a dual pull release lock system, which may be, for example, a dual pull release lock system for a front cover.

In the present disclosure, the lock system includes a lock body 100, a latch bolt 200, a pawl 300, an electric unlocking part 400, a manual unlocking part 500, an emergency unlocking part 600, and the like.

The lock body 100 may be formed as a housing part of the lock system of the present disclosure, for example, it may include a back plate, a cover body, and other structures, and accordingly, components such as the lock tongue 200, the pawl 300, the electric unlocking part 400, the manual unlocking part 500, and the emergency unlocking part 600 may be mounted on the back plate and/or the cover body, and the mounting manner of these components may be implemented in a manner of the prior art, which is not repeated herein.

The locking bolt 200 is rotatably provided to the lock body 100 and has a full lock position, a half lock position, and an unlock position, in other words, when the locking bolt 200 is rotated in a first direction, it can be moved from the full lock position to the half lock position and then further moved to the unlock position, thereby unlocking the lock system, and on the other hand, when the locking bolt 200 is rotated in a second direction, it can be moved from the unlock position to the half lock position and then further moved to the full lock position, thereby locking the lock device. In a specific embodiment, as shown in fig. 3, the first direction may be a clockwise direction and the second direction may be a counterclockwise direction. More specifically, the bolt 200 of the lock device shown in fig. 3 is in the full lock position.

In one embodiment, the lock body 100 has a notch formed therein and the locking bolt 200 has a recess formed therein. In actual use, the lock body 100 can be secured to one of the vehicle body or the hatch, and correspondingly, the striker can be secured to the other of the vehicle body or the hatch. At this time, the striker is held between the latch bolt 200 and the lock body 100 by the cooperation of the latch bolt 200 and the lock body 100, thereby achieving the locking of the front cover.

The pawl 300 is rotatably disposed on the lock body 100 and has a first position, a second position, and a third position, wherein the pawl 300 is capable of restricting the locking bolt 200 to a fully locked position when the pawl 300 is in the first position, the pawl 300 is capable of restricting the locking bolt 200 to a half-locked position when the pawl 300 is in the second position, and releasing the locking bolt 200 and causing the locking bolt 200 to be in an unlocked position when the pawl 300 is in the third position.

Taking fig. 3 as an example, when the pawl 300 rotates clockwise, it can gradually move away from the latch bolt 200 and release the latch bolt 200. In other words, when the pawl 300 rotates clockwise, it can move from the first position to the second position, and further, to the third position. Conversely, as the pawl 300 moves in a counter-clockwise direction, it can progressively approach the locking bolt 200 and hold the locking bolt in a half-lock position or in a full-lock position. In the present disclosure, the clockwise movement of the pawl 300 can be driven to rotate by the electric unlocking part 400, the manual unlocking part 500, and the emergency unlocking part 600 described below, and the counterclockwise movement of the pawl 300 can be achieved by the restoring force of the restoring torsion spring. The present disclosure will not be repeated with respect to the installation manner of the reset torsion spring.

The electric unlocking part 400 is rotatably provided to the lock body 100, and the electric unlocking part 400 can be driven to rotate by an electric unlocking device, and the pawl 300 is driven to rotate by the rotation of the electric unlocking part 400.

The lock system of the present disclosure may further include an actuator (not shown in the drawings), and it should be understood by those skilled in the art that the actuator may have two bowden cables, one bowden cable is connected to the electric unlocking portion 400, and the other bowden cable is directly or indirectly connected to the locking bolt 200, so that when the motor of the actuator rotates in one direction, the electric unlocking portion 400 can be driven to act, thereby implementing the unlocking operation of the lock device, and correspondingly, when the motor rotates in the other direction, the locking bolt 200 can be driven to rotate, thereby implementing the locking operation.

That is, in the present disclosure, locking and unlocking of the lock system can be achieved by one actuator.

Specifically, taking fig. 3 as an example, when the electric unlocking part 400 is pulled to the left, the electric unlocking part 400 moves counterclockwise, and at this time, the electric unlocking part 400 can move from the initial position to the intermediate position, and further can move to the final position.

In other words, the electric unlocking part 400 may include an initial position, a middle position, and an end position. When the electric unlocking part 400 is positioned at the initial position, it can be in contact with the pawl 300 positioned at the first position or has a preset interval, accordingly, when the electric unlocking part 400 is driven, it can drive the pawl 300 to move from the first position to the second position, and when the electric unlocking part 400 is driven, it can drive the pawl 300 to move from the second position to the third position, at this time, the electric unlocking part 400 has a certain idle stroke, that is, when the electric unlocking part 400 is driven, in the stroke from the initial position to the intermediate position, and is not in contact with the pawl 300, and then, the electric unlocking part 400 drives the pawl 300 to move from the second position to the third position in the stroke from the intermediate position to the end position.

Similarly, the manual unlocking part 500 is rotatably provided to the lock body 100, and the manual unlocking part 500 can be manually driven to rotate, wherein the electric unlocking part 400 is driven to rotate by the manual unlocking part 500 when the manual unlocking part 500 is driven to rotate, and in a preferred embodiment, the manual unlocking part 500 and the electric unlocking part 400 have the same rotation axis, for example, the electric unlocking part 400 and the manual unlocking part 500 may be hinged to the lock body 100 through the same hinge shaft.

In the present disclosure, a protruding portion may be disposed at one side of the electric unlocking portion 400, and the manual unlocking portion 500 may be engaged with the protruding portion when driven to rotate, so that the electric unlocking portion 400 may be driven to rotate together. Accordingly, when the electric unlocking part 400 is driven to rotate, the protruding part of the electric unlocking part 400 can be separated from the manual unlocking part 500, thereby enabling the electric unlocking part 400 to rotate alone without driving the manual unlocking part 500 to rotate. Accordingly, when the manual unlocking portion 500 is not rotated, the emergency unlocking portion 600 mounted on the manual unlocking portion 500 does not operate.

Similarly, the manual unlocking part 500 also includes an initial position, a middle position, and a final position, and more preferably, the initial position, the middle position, and the final position of the manual unlocking part 500 are at the same or substantially the same position as the initial position, the middle position, and the final position of the electric unlocking part 400. When the manual unlocking part 500 is driven to rotate, it can move from an initial position to an intermediate position or from the initial position to an end position.

In addition, the electric unlocking part 400 can realize reverse rotation by the restoring force provided by the torsion spring, namely, the electric unlocking part 400 can move from the final position to the initial position or from the middle position to the initial position by the restoring force provided by the torsion spring. On the other hand, when the electric unlocking part 400 is not driven and the manual unlocking part 500 is driven to unlock, the restoring force provided by the torsion spring can cause the manual unlocking part 500 and the electric unlocking part 400 to rotate in opposite directions together, that is, to move from the end position to the initial position together or from the intermediate position to the initial position together.

In a preferred embodiment, as shown in fig. 2, the electric unlocking portion 400 is provided with a limit post 401, the lock body 100 is provided with a limit groove 101, when the electric unlocking portion 400 rotates, the limit post 401 can slide in the limit groove 101, accordingly, one end position of the limit groove 101 corresponds to the initial position of the electric unlocking portion 400, and the other end position of the limit groove 101 corresponds to the final position of the electric unlocking portion 400.

As shown in fig. 4, the electric unlocking unit 400 can be restricted to the neutral position by the clutch actuator 700. In the present disclosure, one end of the clutch actuator 700 is hinged to the lock body 100, the other end of the clutch actuator 700 is formed as a hook portion, and the clutch actuator 700 can be driven by the latch bolt 200, when the latch bolt is located at the full-lock position, the other end of the clutch actuator 700 is located at the highest position, and after the electric unlocking portion 400 is driven and leaves the initial position, the limit post 401 of the electric unlocking portion 400 can slide into the hook portion of the clutch actuator 700, and at this time, the electric unlocking portion 400 can be limited by the clutch actuator 700 and is located at the intermediate position.

When the electric unlocking part 400 is located at the middle position, the pawl 300 can be driven from the first position to the second position, and the lock tongue 200 rotates and moves from the full locking position to the half locking position. Accordingly, the clutch actuator 700 will be separated from the latch bolt 200, a predetermined interval exists between the clutch actuator 700 and the latch bolt 200, and the clutch actuator 700 will be allowed to rotate counterclockwise (as illustrated in fig. 4).

Then, when the electric unlocking part 400 is reset from the intermediate position to the initial position, the limit post 401 of the electric unlocking part 400 is disengaged from the hook-shaped part, the clutch actuator 700 rotates counterclockwise under the action of the reset force provided by the torsion spring, and accordingly, the other end (i.e., the end having the hook-shaped part) of the clutch actuator 700 is lowered to the preset position, and when the electric unlocking part 400 is driven to rotate again, it is not engaged with the electric unlocking part 400, the electric unlocking part 400 is allowed to move directly from the initial position to the final position, and the pawl 300 is pushed to move to the third position, thereby unlocking the lock system.

That is, the lock system of the present disclosure is a double pull release lock system, in which only the electric unlocking part 400 is allowed to move from the initial position to the intermediate position due to the restriction of the clutch actuator 700 at the time of the first pulling operation, at this time, the electric unlocking part 400 is reset to the initial position, and then, the electric unlocking part 400 is moved from the initial position to the end position at the time of the second pulling operation, thereby achieving unlocking of the lock system.

Similarly, the movement processes of operating the manual unlocking part 500 and operating the electric unlocking part 400 are detailed, and will not be described in detail in this disclosure.

The emergency unlocking section will be described below as an important part of the present disclosure.

As shown in fig. 5, the emergency unlocking portion 600 is rotatably provided to the manual unlocking portion 500, wherein the emergency unlocking portion 600 is configured to drive the pawl 300 from the second position to the third position.

In other words, in the present disclosure, the emergency unlocking portion 600 is only used to drive the pawl 300 from the second position to the third position, and is not capable of driving the pawl 300 from the first position to the second position.

That is, when the pawl 300 is located at the first position and the electric unlocking part 400 and/or the manual unlocking part 500 are rotated, the emergency unlocking part 600 does not interfere with the pawl 300. In a specific embodiment, the second extension 602 of the emergency unlocking unit 600 can contact with the surface of the pawl 300 and can slide relatively, and at this time, as shown in fig. 7, even if the pawl 300 moves clockwise, the second extension 602 does not engage with the pawl 300, and accordingly, the second extension 602 can slide along the upper end surface of the pawl 300.

In a preferred embodiment, the emergency unlocking part 600 includes a retracted position and an extended position, the emergency unlocking part 600 being located at the retracted position when the manual unlocking part 500 is located at the initial position, and the emergency unlocking part 600 being moved from the retracted position to the extended position when the manual unlocking part 500 is driven to rotate and is moved away from the initial position. More specifically, when the manual unlocking portion 500 moves to the intermediate position, the emergency unlocking portion 600 is located at the extended position.

When the emergency unlocking part 600 is located at the retracted position and the electric unlocking part 400 is driven to rotate, the emergency unlocking part 600 does not interfere with the pawl 300. In other words, when the electric unlocking part 400 is driven at this time, it moves independently, and at this time, the manual unlocking part 500 does not act, and accordingly, the emergency unlocking part 600 does not interfere with the pawl 300.

As shown in fig. 6, the locking bolt 200 of the lock system is in the fully locked position and the pawl 300 is in the first position. When the manual unlocking unit 500 is driven, the lock system is in the state shown in fig. 7.

As shown in fig. 7, at this time, the manual unlocking part 500 and the electric unlocking part 400 are rotated together, and the pawl 300 is moved by the interference of the electric unlocking part 400 and the pawl 300, and then the lock system is in the state shown in fig. 8.

As shown in fig. 8, the electric unlocking part 400 can drive the pawl 300 to move from the first position to the second position.

It will be appreciated by those skilled in the art that when the electric unlocking part 400 is driven, the manual unlocking part 500 does not rotate, and accordingly, the electric unlocking part 400 independently drives the pawl 300 from the first position to the second position.

After the state shown in fig. 8, the electric unlocking part 400 and the manual unlocking part 500 are reset to the state shown in fig. 9.

When the manual unlocking part 500 is driven for the second time, as shown in fig. 9, since the pawl 300 is at the second position, the emergency unlocking part 600 can interfere with the pawl 300, and the pawl 300 is driven to act by the emergency unlocking part 600, accordingly, the pawl 300 can be driven from the second position to the third position, the movement process is as shown in fig. 10 and 11, and in fig. 11, the pawl 300 is at the third position, and the lock system is unlocked.

Referring again to the structure shown in fig. 6, in the present disclosure, the lock body 100 is provided with a first limiting portion 102, and the emergency unlocking portion 600 is limited to the retracted position by the contact of the emergency unlocking portion 600 with the first limiting portion 102.

Also, the emergency unlocking part 600 is rotatably connected to the manual unlocking part 500 by a pin shaft, on which a coil spring is wound, and the emergency unlocking part 600 is moved from a retracted position to an extended position by a restoring force provided by the coil spring.

The manual unlocking portion 500 is provided with a second limiting portion 501, and the emergency unlocking portion 600 is limited to an extended position by the second limiting portion 501.

Structurally, as shown in fig. 5 and 6, the emergency unlocking portion 600 includes a first extension member 601 and a second extension member 602 connected to each other, wherein the first extension member 601 is capable of interfering with the second limiting portion 501, and the second extension member 602 is capable of interfering with the pawl 300, and at this time, a connection portion between the first extension member 601 and the second extension member 602 is hinged to the manual unlocking portion 500.

More preferably, as shown in fig. 10 and 11, the pawl 300 is provided with a groove portion, and one end of the second extension member 602 can abut against a sidewall of the groove portion to drive the pawl 300 to rotate.

The second extension member 602 includes a guiding surface 603, where the guiding surface 603 may cooperate with the first limiting portion 102, and when the manual unlocking portion 500 leaves the preset angle at the initial position, the first limiting portion 102 is in sliding contact with the guiding surface 603, so that the emergency unlocking portion 600 may rotate, and has a movement trend from the retracted position to the working position, so that by setting the guiding surface 603, a movement track of the emergency unlocking portion 600 may be accurately controlled, so that a function of the emergency unlocking portion 600 meets a design requirement.

In a preferred embodiment, the emergency release portion 600 is positioned at the extended position within a predetermined angle before the manual release portion 500 is moved to the intermediate position, thereby enabling the emergency release portion 600 to be conveniently engaged with the pawl 300.

In the present disclosure, the bolt 200 may be driven to a half-lock position or a full-lock position by an actuator, at which time the lock system of the present disclosure may further include a lifter 800 and a spring connecting the lifter 800 and the lock body 100. The structures such as the lifting member 800 and the spring may be implemented by using schemes in the prior art, and this disclosure will not be repeated.

Overall, the lock system of the present disclosure can achieve an unlocking function even if the electric unlocking function fails when in use. Specifically, when the electric unlocking function is normal, the actuator can be controlled to pull the electric unlocking portion to rotate, and when the electric unlocking portion rotates for the first time, it can be moved from the initial position to the intermediate position, and held at the intermediate position (at this time, the pawl will be pushed from the first position to the second position). The actuator can be controlled to pull the electric unlocking part to rotate again, and when the electric unlocking part rotates for the second time, the actuator can directly move from the initial position to the final position and push the pawl to the third position from the second position, so that unlocking of the lock system is realized.

If the electric unlocking function fails during execution, for example when the electric unlocking part is held in the intermediate position, the actuator fails, and the electric unlocking part will be in the intermediate position and cannot be reset, the pawl is also driven to the second position. At this time, the manual unlocking portion is manually driven to rotate and is separated from the initial position. When the manual unlocking part moves from the initial position to the intermediate position (the manual unlocking part cannot pass through the intermediate position because the electric unlocking part is at the intermediate position), the pawl is pushed to move from the second position to the third position, and unlocking of the lock system is realized.

In addition, when the electric unlocking function is completely disabled, unlocking can be achieved through the manual unlocking part, specifically, when the manual unlocking part is driven to rotate for the first time, the manual unlocking part can move from an initial position to an intermediate position, the manual unlocking part can drive the electric unlocking part to rotate, the pawl is driven to move from a first position to a second position through rotation of the electric unlocking part, then the manual unlocking part and the electric unlocking part are restored to the initial position, then the manual unlocking part is driven again, after the manual unlocking part leaves the initial position, the emergency unlocking part moves from a retracted position to an extended position and is matched with the pawl, and when the manual unlocking part moves from the initial position to the intermediate position, the pawl is driven to move from the second position to a third position, and unlocking of the locking system is achieved. That is, when the lock is unlocked by the manual unlocking portion, the second driving of the manual unlocking portion does not require the manual unlocking portion to be driven to the end position, and thus the unlocking of the lock system can be completed.
