[0053] The present disclosure will be further described in detail below in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant content and do not limit the present disclosure. Additionally, it should be noted that for the sake of convenience of description, only the parts related to the present disclosure are shown in the drawings.

[0054] It should be noted that, without conflict, the embodiments in the present disclosure and the features in the embodiments can be combined with each other. The technical solutions of the present disclosure will be described in detail below with reference to the accompanying drawings and embodiments.

[0055] Unless otherwise specified, the illustrated exemplary embodiments will be understood to provide exemplary features of various details of some ways in which the technical concept of the present disclosure can be implemented in practice. Thus, unless otherwise specified, the features of the various embodiments can be additionally combined, separated, interchanged, and / or rearranged without departing from the technical concept of the present disclosure.

[0056] In the drawings, the use of cross-hatching and / or shading is generally used to make the boundaries between adjacent components clear. Thus, unless stated otherwise, the presence or absence of cross-hatching or shading does not convey or imply any preference or requirement regarding the specific materials, material properties, dimensions, proportions, commonalities between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. Additionally, in the drawings, for clarity and / or descriptive purposes, the dimensions and relative dimensions of components may be exaggerated. When the exemplary embodiments can be implemented differently, the specific process orders may be performed in an order different from that described. For example, two consecutively described processes may be performed substantially simultaneously or in an order opposite to that described. Further, the same reference numerals denote the same components.

[0057] When a component is referred to as being "on" or "above" another component, "connected to" or "coupled to" another component, the component can be directly on, directly connected to, or directly coupled to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to" or "directly coupled to" another component, there are no intermediate components. For this reason, the term "connected" can refer to a physical connection, an electrical connection, etc., and can have or not have intermediate components.

[0058] For descriptive purposes, the present disclosure may use spatial relative terms such as "under", "below", "beneath", "down", "above", "on", "over", "upper", and "side (e.g., as in "sidewall")" to describe the relationship of one component to another (other) component as shown in the drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as "under" or "beneath" another component or feature will then be positioned "above" the other component or feature. Thus, the exemplary term "under" can encompass both "above" and "below" orientations. Further, the device may be otherwise positioned (e.g., rotated 90 degrees or at other orientations), and accordingly, the spatial relative descriptors used herein are to be interpreted.

[0059] The terms used herein are for the purpose of describing particular embodiments and are not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms "a", "an", and "the" are also intended to include the plural forms. Additionally, when the terms "comprising" and / or "including" and their variants are used in this specification, it is stated that there are the stated features, integers, steps, operations, components, assemblies, and / or groups thereof, but it does not preclude the presence or addition of one or more other features, integers, steps, operations, components, assemblies, and / or groups thereof. It should also be noted that, as used herein, the terms "substantially", "about", and other similar terms are used as approximate terms and not as terms of degree, so they are used to explain the inherent deviations of measured values, calculated values, and / or provided values that would be recognized by a person of ordinary skill in the art.

[0060] Figure 1 is a schematic structural view of a lock system according to an embodiment of the present disclosure. Figure 2 is a schematic structural view of another angle of the lock system according to an embodiment of the present disclosure.

[0061] As Figure 1 and Figure 2 shown, the present disclosure provides a lock system, particularly a double-pull release lock system, for example, it can be a double-pull release lock system for the front cover in a [specific context].

[0062] In the present disclosure, the lock system includes components such as a lock body 100, a locking tongue 200, a pawl 300, an electric unlocking part 400, a manual unlocking part 500, and an emergency unlocking part 600.

[0063] 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. Correspondingly, components such as the locking tongue 200, the pawl 300, the electric unlocking part 400, the manual unlocking part 500, and the emergency unlocking part 600 can be installed on the back plate and / or the cover body. Regarding the installation methods of these components, the methods in the prior art can be used to implement them, and the present disclosure will not elaborate one by one.

[0064] Figure 3 is a schematic internal structural view of a lock system according to an embodiment of the present disclosure.

[0065] The bolt 200 is rotatably disposed on the lock body 100 and has a fully locked position, a semi-locked position, and an unlocked position; in other words, when the bolt 200 rotates in the first direction, it can move from the fully locked position to the semi-locked position and then further to the unlocked position, thereby realizing the unlocking of the lock system; on the other hand, when the bolt 200 rotates in the second direction, it can move from the unlocked position to the semi-locked position and then further to the fully locked position, thereby realizing the locking of the lock device. In a specific embodiment, as Figure 3 shown, the first direction may be the clockwise direction, and the second direction may be the counterclockwise direction. More specifically, Figure 3 the bolt 200 of the lock device shown is in the fully locked position.

[0066] In one embodiment, a notch is formed on the lock body 100, and a recess is formed on the bolt 200. In actual use, the lock body 100 can be fixed to one of the vehicle body or the hatch cover, and correspondingly, the striker can be fixed to the other of the vehicle body or the hatch cover. At this time, the striker can be held between the bolt 200 and the lock body 100 through the cooperation of the bolt 200 and the lock body 100, thereby realizing the locking of the front cover.

[0067] Figure 4 is a partial structural schematic diagram of a lock system according to an embodiment of the present disclosure.

[0068] The pawl 300 is rotatably disposed on the lock body 100 and has a first position, a second position, and a third position. Among them, when the pawl 300 is in the first position, the pawl 300 can limit the bolt 200 in the fully locked position; when the pawl 300 is in the second position, the pawl 300 can limit the bolt 200 in the semi-locked position; when the pawl 300 is in the third position, the bolt 200 is released and the bolt 200 is in the unlocked position.

[0069] Taking Figure 3 as an example, when the pawl 300 rotates clockwise, it can gradually move away from the bolt 200 and release the 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. In the reverse process, when the pawl 300 rotates counterclockwise, it can gradually approach the bolt 200 and hold the bolt in the semi-locked position or the fully locked position. In the present disclosure, the clockwise movement of the pawl 300 can be driven by the following electric unlocking part 400, manual unlocking part 500, and emergency unlocking part 600 to rotate, and the counterclockwise movement of the pawl 300 can be realized by the restoring force of the return torsion spring. Regarding the installation method of this return torsion spring, the present disclosure will not be elaborated one by one.

[0070] The electric unlocking part 400 is rotatably arranged on the lock body 100, and the electric unlocking part 400 can be driven to rotate by an electric unlocking device; and by the rotation of the electric unlocking part 400, the pawl 300 is driven to rotate.

[0071] The lock system of the present disclosure may further include an actuator (not shown in the figure). Those skilled in the art should know that the actuator may have two Bowden cables. One Bowden cable is connected to the electric unlocking part 400, and the other Bowden cable is directly or indirectly connected to the lock tongue 200. Thus, when the motor of the actuator rotates in one direction, the electric unlocking part 400 can be driven to act, so as to realize the unlocking operation of the lock device. Correspondingly, when the motor rotates in the other direction, the lock tongue 200 can be driven to rotate, so as to realize the locking operation.

[0072] That is to say, in the present disclosure, the locking and unlocking of the lock system can be realized by one actuator.

[0073] Specifically, taking Figure 3 as an example, when the electric unlocking part 400 is pulled to the left, the electric unlocking part 400 will generate a counterclockwise movement. At this time, the electric unlocking part 400 can move from the initial position to the intermediate position, and further can move to the end position.

[0074] In other words, the electric unlocking part 400 may include an initial position, an intermediate position and an end position. When the electric unlocking part 400 is located at the initial position, it can contact the pawl 300 located at the first position or have a preset interval. Correspondingly, when the electric unlocking part 400 is driven to move from the initial position to the intermediate position, it can drive the pawl 300 to move from the first position to the second position; moreover, when the electric unlocking part 400 is driven to move from the initial position to the end position, it can drive the pawl 300 to move from the second position to the third position. At this time, the electric unlocking part 400 will have a dead stroke. That is to say, when the electric unlocking part 400 is driven to move from the initial position to the end position, during the stroke of the electric unlocking part 400 from the initial position to the intermediate position, it does not contact the pawl 300. Then, during the stroke of the electric unlocking part 400 from the intermediate position to the end position, the pawl 300 is driven to move from the second position to the third position.

[0075] Similarly, the manual unlocking part 500 is rotatably arranged on the lock body 100, and the manual unlocking part 500 can be manually driven to rotate. When the manual unlocking part 500 is driven to rotate, the electric unlocking part 400 is driven by the manual unlocking part 500 to rotate. 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 can be hinged to the lock body 100 through the same hinge shaft.

[0076] In the present disclosure, a protrusion can be provided on one side of the electric unlocking part 400. When the manual unlocking part 500 is driven to rotate, it can cooperate with the protrusion, so as to drive the electric unlocking part 400 to rotate together. Correspondingly, when the electric unlocking part 400 is driven to rotate, the protrusion of the electric unlocking part 400 can be separated from the manual unlocking part 500, so that the electric unlocking part 400 can rotate independently without driving the manual unlocking part 500 to rotate. Correspondingly, when the manual unlocking part 500 does not rotate, the emergency unlocking part 600 installed on the manual unlocking part 500 will not act.

[0077] Similarly, the manual unlocking part 500 also includes an initial position, an intermediate position and an end position. More preferably, the initial position, the intermediate position and the end position of the manual unlocking part 500 are in the same or approximately the same position as the initial position, the intermediate position and the end position of the electric unlocking part 400. When the manual unlocking part 500 is driven to rotate, it can move from the initial position to the intermediate position, or from the initial position to the end position.

[0078] In addition, the electric unlocking part 400 can realize reverse rotation through the restoring force provided by the torsion spring, that is, the restoring force provided by the torsion spring can make the electric unlocking part 400 move from the end position to the initial position, or from the intermediate position to the initial position. 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 make the manual unlocking part 500 and the electric unlocking part 400 rotate in reverse together, that is, move from the end position to the initial position together, or from the intermediate position to the initial position.

[0079] In a preferred embodiment, as Figure 2As shown, a limit post 401 is provided on the electric unlocking part 400, and a limit groove 101 is formed on the lock body 100. When the electric unlocking part 400 rotates, the limit post 401 can slide in the limit groove 101. Correspondingly, one end position of the limit groove 101 corresponds to the initial position of the electric unlocking part 400, and the other end position of the limit groove 101 corresponds to the end position of the electric unlocking part 400.

[0080] As Figure 4 shown, the electric unlocking part 400 can be restricted to an intermediate position by the clutch actuator 700. In the present disclosure, one end of the clutch actuator 700 is hinged to the lock body 100, and the other end is formed into a hook part. Moreover, the clutch actuator 700 can be driven by the lock tongue 200. When the lock tongue is in the fully locked position, the other end of the clutch actuator 700 is at the highest position. At this time, after the electric unlocking part 400 is driven and leaves the initial position, the limit post 401 of the electric unlocking part 400 can slide into the hook part of the clutch actuator 700. At this time, the electric unlocking part 400 can be restricted in position by the clutch actuator 700 and is in the intermediate position.

[0081] When the electric unlocking part 400 is in the intermediate position, the pawl 300 can be driven from the first position to the second position. At this time, the lock tongue 200 will rotate and move from the fully locked position to the half-locked position. Correspondingly, the clutch actuator 700 will be separated from the lock tongue 200, and there is a preset interval between the clutch actuator 700 and the lock tongue 200. The clutch actuator 700 will be allowed to rotate counterclockwise (taking Figure 4 as an example).

[0082] 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 will disengage from the hook part. Under the action of the restoring force provided by the torsion spring, the clutch actuator 700 rotates counterclockwise. Correspondingly, the other end of the clutch actuator 700 (i.e., the end with the hook part) will drop to a preset position. At this position, when the electric unlocking part 400 is driven to rotate again, it will not cooperate with the electric unlocking part 400, and the electric unlocking part 400 will be allowed to directly move from the initial position to the end position and push the pawl 300 to the third position to realize the unlocking of the lock system.

[0083] That is to say, the lock system of the present disclosure is a double-pull release lock system. During the first pulling operation, due to the restriction of the clutch actuator 700, only the electric unlocking part 400 is allowed to move from the initial position to the intermediate position. At this time, the electric unlocking part 400 is reset to the initial position. Then, during the second pulling operation, the electric unlocking part 400 will move from the initial position to the end position to realize the unlocking of the lock system.

[0084] Similarly, the detailed movement process of operating the manual unlocking part 500 and the electric unlocking part 400 will not be elaborated one by one in this disclosure.

[0085] The following will describe the key part of this disclosure, the emergency unlocking part.

[0086] Figure 5 It is a schematic structural diagram of the emergency unlocking part of the lock system according to an embodiment of this disclosure.

[0087] As Figure 5 shown, the emergency unlocking part 600 is rotatably arranged on the manual unlocking part 500. Among them, the emergency unlocking part 600 is used to drive the pawl 300 from the second position to the third position.

[0088] In other words, in this disclosure, the emergency unlocking part 600 is only used to drive the pawl 300 from the second position to the third position, and cannot drive the pawl 300 from the first position to the second position.

[0089] That is, when the pawl 300 is in the first position, and the electric unlocking part 400 and / or the manual unlocking part 500 rotates, the emergency unlocking part 600 does not interfere with the pawl 300. In a specific embodiment, the second extension part 602 of the emergency unlocking part 600 can contact the surface of the pawl 300 and can slide relatively. At this time, as Figure 7 shown, even if the pawl 300 generates a clockwise movement, the second extension part 602 will not cooperate with the pawl 300. Correspondingly, the second extension part 602 can slide along the upper end surface of the pawl 300.

[0090] In a preferred embodiment, the emergency unlocking part 600 includes a retracted position and an extended position. When the manual unlocking part 500 is in the initial position, the emergency unlocking part 600 is in the retracted position; when the manual unlocking part 500 is driven to rotate and leaves the initial position, the emergency unlocking part 600 moves from the retracted position to the extended position. More specifically, when the manual unlocking part 500 moves to the intermediate position, the emergency unlocking part 600 is in the extended position.

[0091] When the emergency unlocking part 600 is in 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, at this time, when the electric unlocking part 400 is driven, it will move independently. At this time, the manual unlocking part 500 will not generate an action. Correspondingly, the emergency unlocking part 600 will not interfere with the pawl 300 either.

[0092] Figures 6 to 11 Schematic diagram of the movement state of the emergency unlocking part according to an embodiment of the present disclosure.

[0093] As Figure 6 shown, the locking tongue 200 of the lock system is in the fully locked position, and the pawl 300 is in the first position. At this time, when the manual unlocking part 500 is driven, the lock system will be in the Figure 7 state shown.

[0094] As Figure 7 shown, at this time, the manual unlocking part 500 and the electric unlocking part 400 rotate together, and through the interference between the electric unlocking part 400 and the pawl 300, the pawl 300 moves, and then the lock system will be in the Figure 8 state shown.

[0095] As Figure 8 shown, the electric unlocking part 400 can drive the pawl 300 to move from the first position to the second position.

[0096] Those skilled in the art should know that when the electric unlocking part 400 is driven, the manual unlocking part 500 will not rotate. Correspondingly, the electric unlocking part 400 independently drives the pawl 300 from the first position to the second position.

[0097] After Figure 8 the state shown, the electric unlocking part 400 and the manual unlocking part 500 will reset to the Figure 9 state shown.

[0098] As Figure 9 shown, when the manual unlocking part 500 is driven for the second time, since the pawl 300 is in the second position at this time, the emergency unlocking part 600 will be able to interfere with the pawl 300 and drive the pawl 300 to act through the emergency unlocking part 600. Correspondingly, the pawl 300 can be driven from the second position to the third position, and its movement process is as Figure 10 and Figure 11 shown. In Figure 11 , the pawl 300 is in the third position, and at this time the lock system will be unlocked.

[0099] Referring again to Figure 6 the structure shown in, in the present disclosure, a first limiting part 102 is provided on the lock body 100. Through the contact between the emergency unlocking part 600 and the first limiting part 102, the emergency unlocking part 600 is restricted in the retracted position.

[0100] Moreover, the emergency unlocking part 600 is rotatably connected to the manual unlocking part 500 through a pin shaft. A torsion spring is wound around the pin shaft, and the emergency unlocking part 600 is moved from the retracted position to the extended position by the restoring force provided by the torsion spring.

[0101] A second limiting part 501 is provided on the manual unlocking part 500, and the emergency unlocking part 600 is limited at the extended position by the second limiting part 501.

[0102] Structurally, as Figure 5 and Figure 6 shown, the emergency unlocking part 600 includes a first extension member 601 and a second extension member 602 that are connected to each other. Among them, the first extension member 601 can interfere with the second limiting part 501, and the second extension member 602 can interfere with the pawl 300. At this time, the connection part of the first extension member 601 and the second extension member 602 is hinged to the manual unlocking part 500.

[0103] More preferably, as Figure 10 and Figure 11 shown, a groove part is provided on the pawl 300, and one end of the second extension member 602 can abut against the side wall of the groove part to drive the pawl 300 to rotate.

[0104] The second extension member 602 includes a guiding surface 603, and the guiding surface 603 can cooperate with the first limiting part 102. Within a preset angle before the manual unlocking part 500 leaves the initial position, the first limiting part 102 is in sliding contact with the guiding surface 603, so that the emergency unlocking part 600 can rotate and has a movement trend from the retracted position to the working position. Thus, through the setting of the guiding surface 603, the movement track of the emergency unlocking part 600 can be accurately controlled, so that the function of the emergency unlocking part 600 meets the design requirements.

[0105] In a preferred embodiment, within a preset angle before the manual unlocking part 500 moves to the middle position, the emergency unlocking part 600 is located at the extended position, so that it is convenient for the emergency unlocking part 600 to cooperate with the pawl 300.

[0106] In the present disclosure, the actuator can drive the locking tongue 200 to move to the half-locked position or the fully-locked position. At this time, the lock system of the present disclosure can further include a lifting member 800 and a spring connecting the lifting member 800 and the lock body 100. The structures such as the lifting member 800 and the spring can be implemented by the solutions in the prior art, and the present disclosure will not elaborate on them one by one.

[0107] Generally speaking, when the lock system of the present disclosure is in use, the unlocking function can be achieved even if the electric unlocking function fails. Specifically, when the electric unlocking function is normal, the actuator can be controlled to pull the electric unlocking part to rotate. When the electric unlocking part rotates for the first time, it can move from the initial position to the intermediate position and be held at this intermediate position (at this time, the pawl will be pushed from the first position to the second position). Then the actuator rotates in the reverse direction and resets the electric unlocking part; then the actuator can be controlled to pull the electric unlocking part to rotate again. When the electric unlocking part rotates for the second time, it can directly move from the initial position to the end position and push the pawl from the second position to the third position to achieve the unlocking of the lock system.

[0108] If a fault occurs during the execution of the electric unlocking function, for example, when the electric unlocking part is held at the intermediate position and a fault occurs in the actuator, at this time, the electric unlocking part will be unable to reset at this intermediate position, and the pawl has also been driven to the second position. At this time, manually drive the manual unlocking part to rotate and leave the initial position. When the manual unlocking part leaves the initial position, the emergency unlocking part will move from the retracted position to the extended position and cooperate with the pawl; when the manual unlocking part moves from the initial position to the intermediate position (since the electric unlocking part is at the intermediate position, the manual unlocking part cannot cross the intermediate position), it will push the pawl from the second position to the third position and achieve the unlocking of the lock system.

[0109] In addition, when the electric unlocking function completely fails, the unlocking can be achieved through the manual unlocking part. Specifically, when the manual unlocking part is driven to rotate for the first time, it can move from the initial position to the intermediate position. Thus, the manual unlocking part can drive the electric unlocking part to rotate, and push the pawl from the first position to the second position through the rotation of the electric unlocking part; then both the manual unlocking part and the electric unlocking part return to the initial position; then drive the manual unlocking part again. When the manual unlocking part leaves the initial position, the emergency unlocking part will move from the retracted position to the extended position and cooperate with the pawl; when the manual unlocking part moves from the initial position to the intermediate position, it will push the pawl from the second position to the third position and achieve the unlocking of the lock system. That is to say, when unlocking through the manual unlocking part at this time, driving the manual unlocking part for the second time does not need to drive the manual unlocking part to the end position, that is, the unlocking of the lock system can be completed.
