Therefore, unless otherwise stated, the features of the various embodiments / examples may be further combined, separated, interchanged, and / or rearranged without departing from the technical concepts of the present disclosure.

[0129] 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 indicated, 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 order described. In addition, the same figure numbers represent the same components.

[0130] When a component is referred to as being “on,” “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 present. For this purpose, the term “connected” may refer to a physical connection, an electrical connection, etc., with or without intervening components.

[0131] For descriptive purposes, the present disclosure may use spatially relative terms such as "below," "beneath," "under," "down," "above," "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.

Figure 4 yes Figure 3 A structural diagram from another angle. Figure 5 Schematic diagram of the structure of a lock system according to one embodiment of the present disclosure (the lock tongue component is in the unlocked position). Figure 6 yes Figure 5 A structural diagram from another angle.

[0134] like Figures 1 to 6As shown, the locking system of the present disclosure can be applied to the hood or door of a motor vehicle, thereby locking the hood or door of the motor vehicle to the vehicle body. For example, the vehicle body may be provided with a lock catch, and the locking system can retain the lock catch, thereby locking the motor vehicle. Conversely, when the locking system releases the lock catch, the hood or door of the motor vehicle can be unlocked.

[0135] In the present disclosure, the lock system includes a lock body 100 , a bolt component 200 , a pawl component 300 and other components.

[0136] The lock body 100 can form the housing portion of the lock system of the present disclosure, for example, it can include a back plate, a cover, and other structures. Accordingly, components such as the lock tongue component 200 and the pawl component 300 can be mounted on the back plate and / or the cover. Regarding the mounting method of these components, methods known in the art can be used, and this disclosure will not elaborate on them one by one.

[0137] 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.

[0138] 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 Figure 5 In the state shown, the bolt component 200 can be rotated clockwise. Figure 1 Turn to the unlocked position shown Figure 3 Shown in the half-locked position.

[0139] 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. Thus, the lock system of the present disclosure can achieve electric locking.

[0140] like Figure 3 As shown, when the lock tongue component 200 located 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.

[0141] In addition, the lock tongue component 200 of the present disclosure can detect its position through a micro switch.

[0142] The following will be combined Figures 1 to 5 The unlocking process is described in the following order.

[0143] During the unlocking process, the lock tongue component 200 can be unlocked by the action of the reset force (the reset force can be provided by the lock tongue component reset spring, such as a coil spring). Figure 1 The fully locked position shown is rotated in a counterclockwise direction, whereby the bolt member 200 can be moved from Figure 1 Turn to the fully locked position shown Figure 3 further, when the pawl member 300 does not limit the position of the tongue member 200, the tongue member 200 can be from Figure 3 Turn to the half-lock position shown Figure 5 to the unlock position shown to complete the unlocking process.

[0144] Figure 7 1 is a schematic structural diagram of a lock tongue component according to an embodiment of the present disclosure. Figure 8 yes Figure 7 A structural diagram from another angle.

[0145] like Figures 1 to 8 As shown, 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.

[0146] 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 ( Figure 7 In the lower side), accordingly, the second feature 202 of the lock tongue is located on the second side of the U-shaped groove 210 ( Figure 7 More preferably, the first lock tongue feature 201 and the second lock tongue feature 202 are both located near the opening of the U-shaped groove 210.

[0147] Figure 9 2 is a schematic structural diagram of a pawl component according to an embodiment of the present disclosure. Figure 10 yes Figure 9 A structural diagram from another angle.

[0148] In this disclosure, Figures 1 to 5 as well as Figure 9 and Figure 10As shown, the pawl component 300 is rotatably provided 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 the 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 the semi-locked position; when the pawl component 300 is in the third position, the lock tongue component 200 can be in the unlocked position. In the present disclosure, the first position and the second position can be the same position or different positions. In the preferred embodiment of the present disclosure, the first position and the second position are the same position. In the process of moving from the first position to the second position, Figure 1 In the direction shown, the pawl component 300 can first rotate counterclockwise to release the bolt component 200, and then rotate clockwise to move to the second position to keep the bolt component 200 in the second position.

[0149] 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.

[0150] Specifically, when the lock system of the present disclosure is in a fully locked state (e.g. Figure 1 In the state shown, the lock tongue component 200 is subjected to a force in the form of a simply supported beam structure. Compared to the cantilever beam structure of a conventional lock tongue component 200 in the fully locked position, the strength of the lock tongue component 200 is significantly improved. Accordingly, the lock tongue component 200 of the present disclosure is not easily damaged by external forces. Moreover, while meeting design requirements, the lock tongue component 200 of the present disclosure can be reduced in size because it is subjected to a force in the form of a simply supported beam structure.

[0151] like Figure 1 As shown, in the present disclosure, when the bolt member 200 is in the fully locked position, the first feature 201 of the bolt and the pawl member 300 are both located on the first side (lower side) of the U-shaped groove 210, and components such as the lock catch (not shown) are located between the rotation axis of the pawl member 300 and the rotation axis of the bolt member 200. As a result, the first arm ( Figure 1 The lower portion of the middle U-shaped groove 210 (ie, the right arm) and the pawl component 300 form a simply supported beam structure.

[0152] 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 planar shape (refer to Figure 1), accordingly, the first feature 201 of the lock tongue is also formed into a substantially planar shape (reference Figure 1 Preferably, a stop surface 205 is formed on the first arm of the lock tongue component 200. 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 leaving the first position.

[0153] In the present disclosure, the pawl member 300 can be driven to rotate. Figure 1 In the state shown, the pawl member 300 is in the first position; when the pawl member 300 is disengaged from the first position by the electric actuator or the manual actuator, the pawl member 300 will move along Figure 1 In the counterclockwise rotation shown, in one case, the pawl component 300 can stop directly in the second position; in another case, the pawl component 300 rotates in the counterclockwise direction and then rotates in the clockwise direction to the second position. Accordingly, when the pawl component 300 is in the second position, the bolt component 200 can rotate to the semi-locked position under the action of the reset force.

[0154] When the pawl member 300 is further driven in the second position, the pawl member 300 is disengaged from the second position, that is, it can move along the Figure 3 The latch member 200 rotates counterclockwise to the third position. Accordingly, when the pawl member 300 is in the third position, the bolt member 200 can rotate to the unlocked position under the action of the reset force, and the lock system is in the unlocked state.

[0155] During the locking process of the lock system, the pawl component 300 can be driven out of the third position and move to the second position and the first position by a reset force provided by a pawl component reset spring (e.g., a coil spring). Figure 5 The pawl component 300 can rotate clockwise under the action of the reset force (the lock tongue component 200 must first be out of the unlocked position, which will be described in detail below). During the locking process of the lock system, the lock tongue component 200 starts to move from the unlocked position, moves to the half-locked position, and then to the fully locked position. During the movement of the lock tongue component 200, it can be driven by components such as the lock buckle described above, for example, Figure 5 The pawl member 300 starts to rotate clockwise during the locking process of the lock system. Under the action of the reset force, the pawl member 300 starts to move from the third position, and moves to the second position, the first position (for example, Figure 5 Clockwise rotation at the start).

[0156] In the present disclosure, during the locking process of the locking system, the pawl component 300 can move clockwise under the action of the reset force, and accordingly, it can also move counterclockwise 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.

[0157] When the lock system is in full lock state (refer to Figure 1 ), the stop surface 205 of the lock tongue component 200 can limit the pawl component 300 in the first position from performing further resetting action, and can prevent the pawl component 300 and the lock tongue component 200 from separating.

[0158] In a preferred embodiment of the present disclosure, the lock system further comprises a locking device 400 and an operating member 500. The locking device 400 is rotatably mounted on the lock body 100 and is used to maintain the pawl member 300 in the first position or the second position. The operating member 500 is rotatably mounted on the lock body 100 and is used to drive the locking device 400 to move. Preferably, the operating member 500 and the locking device 400 have the same rotation axis. Alternatively, the operating member 500 and the locking device 400 may have different rotation axes.

[0159] The present disclosure redesigns the matching mode and matching structure of the locking device 400 and the operating component 500, forming an important invention content of the present disclosure. The two are configured to have the same rotation axis, in other words, have the same rotation axis, 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.

[0160] 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.

[0161] Figure 11 2 is a schematic structural diagram of an operating component according to an embodiment of the present disclosure. Figure 12 yes Figure 11 A structural diagram from another angle. Figure 13 It is a structural schematic diagram of a locking device according to one embodiment of the present disclosure. Figure 14 yes Figure 13 A structural diagram from another angle.

[0162] Combined with the following Figures 1 to 5 The unlocking process of the lock system of the present disclosure will be described again.

[0163] Lock system in Figure 1 In the fully locked state shown, the first end of the locking device 400 holds the first end of the pawl component 300 in a position engaged with the first feature 201 of the lock tongue. At this time, the pawl component 300 is in the first position and the locking device 400 is in the first locked position.

[0164] refer to Figure 1 and Figure 3 as well as Figures 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 an electric actuator via the first feature 501 of the operating portion), the operating component 500 rotates in the direction of releasing the locking device 400 from the pawl component 300, and drives the locking device 400 to rotate in the direction of releasing the locking of the pawl component 300 (counterclockwise in the figure), and the locking device 400 will leave the first locking position.

[0165] In a preferred embodiment of the present disclosure, the operating part 500 is provided with a second operating feature 502, and the second operating feature 502 is located on the first side ( Figure 1 ), when the operating member 500 rotates counterclockwise (refer to Figure 1 ), the locking device 400 is driven to rotate counterclockwise (via the second end portion of the locking device 400 ) via the second feature 502 of the operating portion, and the locking device 400 releases the pawl component 300 .

[0166] When the pawl member 300 is driven to rotate counterclockwise, it can Figure 1 The first position shown moves to 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.

[0167] 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 go 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.

[0168] Accordingly, when the operating member 500 rotates counterclockwise and then clockwise, the operating member 500 can release the pawl member 300. Accordingly, when the lock tongue member 200 leaves the fully locked position, the pawl member 300 will be pressed against the lock tongue member 200 under the action of the reset force, and then move to the fully locked position. Figure 3 The second position shown, thereby maintaining the bolt member 200 in the semi-locked position.

[0169] Lock system in Figure 3 In the semi-locked state shown, when the operating member 500 is driven again and rotated counterclockwise again, it can drive the pawl member 300 to move from the Figure 3 The second position shown moves to Figure 5 In the third position shown, the bolt member 200 moves to the position shown in FIG. Figure 5 The unlocked position shown in FIG. 1 is used to unlock the lock system, thereby achieving unlocking of the lock system and the lock system reaches the unlocked state.

[0170] 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.

[0171] In a preferred embodiment of the present disclosure, the operating member 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 the semi-locked position and the pawl member 300 is in the second position), the first end of the pawl member 300 is held by the first end of the locking device 400, 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, such as Figure 3 ), thereby stably maintaining the bolt member 200 in the semi-locked position. Accordingly, the bolt third feature 203 (located at the end of the second arm of the bolt member 200, and disposed away from the bolt second feature 202) cooperates with the operating portion fourth feature 504, so that the bolt member 200 is maintained in the semi-locked position by the operating portion fourth feature 504 and the first end of the pawl member 300.

[0172] 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 .

[0173] Lock system in Figure 3In the semi-locked state shown, when the first feature 501 of the operating part is driven, so that 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. 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. Figure 5 shown.

[0174] During the unlocking process of the lock system, when the pawl member 300 is located at 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 return 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 part 300 to keep the lock tongue part 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 part 300 in the second position.

[0175] exist Figure 3 In the state shown (the lock system is in a semi-locked state), when the operating member 500 is applied with an external force and rotated counterclockwise, the second feature 502 of the operating portion drives the locking device 400 (drives the second end of the locking device 400), and the locking device 400 rotates counterclockwise, and the locking device 400 will leave the second locking position ( Figure 3 The pawl component 300 is released and driven by the third feature 503 of the operating portion to rotate counterclockwise 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 locking system is Figure 3 The status shown moves to Figure 5 In the state shown, the locking tongue component 200 is located at the unlocking position, and the lock catch in the U-shaped groove 210 will be released.

[0176] refer to Figure 5 and Figure 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. When the pawl component 300 cooperates with (contacts) the third feature 203 of the lock tongue, the lock tongue component 200 remains in the unlocked position.

[0177] In the preferred embodiment of the present disclosure, refer to the attached drawings of the present disclosure. Figures 1 to 5 , the first feature 501 of the operating portion described above in this disclosure is configured on the third feature 503 of the operating portion described above in this disclosure.

[0178] 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. In light of 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 scope of protection of the present disclosure.

[0179] In a preferred embodiment of the present disclosure, the line connecting the third feature 503 of the operating portion and the fourth feature 504 of the operating portion passes through the rotation axis (rotation axis, ie, the third axis) of the operating component 500, or is adjacent to the rotation axis of the operating component 500. Figures 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.

[0180] Combined with the following Figures 1 to 5 To illustrate the locking process of the lock system of the present invention.

[0181] During the locking process of the lock system, the bolt component 200 is driven by components such as the lock catch and moves from the unlocked position to the half-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 bolt component 200, the pawl component 300 can be moved from the third position ( Figure 5 The locking device 400 rotates clockwise under the action of a reset force (such as a reset spring of the locking device, which can be a coil spring), that is, rotates in the direction of locking the pawl member 300. When the locking device 400 moves to the second locking position, the first end of the locking device 400 locks the pawl member 300 in the second position. Figure 3 As shown, 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.

[0182] In some embodiments of the present disclosure, at least a portion of the outer surface of the third arm of the lock tongue component 200 (preferably, the third arm is formed by a transverse extension of the second arm) is formed as a guide surface 204. When the lock tongue component 200 moves from the unlocked position to the semi-locked position, the fourth feature 504 of the operating portion moves in close contact with the guide surface 204 of the lock tongue component 200. More preferably, the guide surface is configured so that when the pawl component 300 is in the second position, the locking device 400 moves to the second position.

[0183] In a preferred embodiment, the locking device 400 is rotatable relative to the operating member 500, and under the action of a reset force provided by a reset spring, the locking device 400 can be brought into close contact with the second feature 502 of the operating portion. During the locking process, the bolt member 200 can drive the pawl member 300 to leave the third position and further rotate clockwise. At this time, the pawl member 300 can push the locking device 400 to rotate counterclockwise and generate relative motion with the operating member 500. At this time, the locking device 400 will not move to the second locked position. Then, when the bolt 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. Correspondingly, 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. At this time, the locking device 400 is in the second locked position.

[0184] In the present disclosure, the locking device 400 can also rotate clockwise together with the operating member 500, and the locking device 400 can keep the pawl member 300 in the second position, and accordingly, the bolt member 200 is kept in the semi-locked position, such as Figure 3 shown.

[0185] Further, Figure 3 The state shown is the starting point. During the locking process of the lock system, the lock tongue component 200 is further driven by 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. 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. The locking device 400 disengages from the second locking position and releases the lock on the pawl component 300. The pawl component 300 is driven by the third feature 503 of the operating part to rotate counterclockwise. 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 towards the fully locked position under the drive of the lock buckle and other components.

[0186] After the end of the first arm of the bolt member 200 is out of contact with the side surface of the first end of the pawl member 300, the pawl member 300 continues to rotate clockwise under the action of the reset force (which can be provided by the pawl member reset spring) and moves to the first position, as shown in FIG. Figure 1 As shown, during this process, the operating component 500 and the locking device 400 rotate clockwise under the action of the reset force they receive, and the locking device 400 moves to the first locking position ( Figure 1The pawl member 300 is locked in the first position. At this time, the fourth feature 504 of the operating portion moves to a position facing the U-shaped groove 210. Preferably, at this time, the fourth feature 504 of the operating portion is located at the opening of the U-shaped groove 210. Figure 1 shown.

[0187] In the present disclosure, during the movement of the lock tongue component 200 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 is locked again in the fully locked position.

[0188] Figure 15 Schematic diagram of the internal structure of a lock system according to one embodiment of the present disclosure.

[0189] like Figure 15 As shown, the operating component 500 of the present disclosure can be driven to rotate by the unlocking motor 101, thereby unlocking the lock system. Specifically, the unlocking motor 101 can be disposed 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 disposed on the lock body 100 and has an A-th axis. Preferably, the A-th axis of the unlocking gear 102 can be perpendicular or approximately perpendicular to the third axis of the operating component 500, thereby enabling the lock system of the present disclosure to be conveniently arranged in components such as the door of a motor vehicle.

[0190] In a preferred embodiment, the output shaft of the unlocking motor 101 is formed as a worm, which is capable of meshing with the teeth on the outer periphery of the unlocking gear 102. In this case, the unlocking gear 102 can also be referred to as an unlocking worm wheel. In the present disclosure, the worm can be a three-start worm, so that the worm and the unlocking gear 102 will not self-lock. That is, in the worm and worm wheel transmission structure of the present disclosure, the rotation of the worm can drive the unlocking gear 102 to rotate, and conversely, when the unlocking gear 102 is driven to rotate, it can also drive the worm to rotate.

[0191] A cam 102A is formed at one axial end face of the unlocking gear 102. The cam surface of the cam 102A is the outer circumference of the cam 102A. When the unlocking gear 102 is driven to rotate, the outer circumference of the cam 102A can drive the unlocking lever 103 to rotate, and the unlocking lever 103 contacts the operating member 500 to unlock the lock system.

[0192] 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. Moreover, the A-th axis is disposed parallel to the B-th axis and spaced a certain distance apart.

[0193] In the present disclosure, the unlocking lever portion 103 may include an unlocking lever first feature 103A, wherein the unlocking lever first feature 103A may be formed as an arm portion of the unlocking lever portion 103, so that when the unlocking lever first feature 103A contacts the surface of the cam 102A and is driven by the cam 102A, the unlocking lever portion 103 can be applied with an unlocking torque by the cam 102A.

[0194] 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.

[0195] 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. Accordingly, the inner opening rod portion 104 has a C-axis, wherein the C-axis, the A-axis and the B-axis are all arranged in parallel and spaced apart by a preset distance.

[0196] 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. Figure 4 In addition, when the external force applied by the inner opening cable lock is withdrawn, the inner opening rod portion 104 can rotate counterclockwise under the effect of the restoring force of a reset element such as a coil spring and be maintained at a preset initial position.

[0197] The inner opening lever portion 104 further includes a second inner opening lever feature 104B, which is also formed as an arm portion of the inner opening lever portion 104. Thus, through the cooperation of the second inner opening lever feature 104B and the unlocking lever portion 103, the inner opening lever portion 104 can drive the unlocking lever portion 103 to rotate. More preferably, the unlocking lever portion 103 includes a third unlocking lever feature 103C, and accordingly, the second inner opening lever feature 104B can cooperate with the third unlocking lever feature 103C.

[0198] In one embodiment, Figure 15 As shown, 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.

[0199] Figure 16 is another schematic diagram of the internal structure of a lock system according to one embodiment of the present disclosure.

[0200] like Figure 15 and Figure 16 As shown, 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.

[0201] Specifically, Figure 15 In the direction shown, the super lock push rod portion 105 can be driven and moved to the left, and can be in Figure 16 The super lock push rod portion 105 is in the position shown, 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 separated 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.

[0202] 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.

[0203] On the other hand, when the super lock push rod portion 105 is rotated after pushing the unlocking rod portion 103, the super lock push rod portion 105 can be restricted in position, so that the unlocking rod portion 103 cannot be driven to rotate, that is, at this moment, even if the unlocking motor 101 is powered, the unlocking motor 101 cannot push the unlocking rod portion 103 to rotate, and accordingly, unlocking cannot be achieved. In other words, at this moment, only by first removing the restriction of the unlocking rod portion 103 by the super lock push rod portion 105 can the lock system be opened. On the other hand, when the unlocking motor 101 is energized and drives the unlocking rod portion 103 to rotate, the unlocking rod portion 103 can push the super lock push rod portion 105 to move, and now the super lock push rod portion 105 can move to the right, and accordingly, the super lock push rod portion 105 can only achieve the function of preventing manual unlocking, and it cannot prevent electric unlocking. In other words, no matter which position the super lock push rod portion 105 is in, the electric unlocking function of the lock system is always effective.

[0204] Figure 17 2 is another schematic diagram of the internal structure of a lock system according to one embodiment of the present disclosure.

[0205] like Figure 17 As shown, 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 energized 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 be engaged 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 here one by one.

[0206] Figure 18 It is a structural schematic diagram of a super lock push rod gear according to an embodiment of the present disclosure.

[0207] like Figure 18 As shown, 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.

[0208] 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.

[0209] At this time, when the super lock push rod motor 121 rotates in the forward or reverse direction, it can drive the super lock push rod portion 105 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, it can drive the super lock push rod gear 122 to rotate. 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.

[0210] 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 the limiting structure set 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.

[0211] Refer again Figure 16 The lock system disclosed in the present invention also includes a lock core rod portion 123, which has a D-th axis, wherein the D-th axis can be set parallel to the first axis, so that when the user unlocks the lock by using a key or other components, the lock core rod portion 123 can be rotated.

[0212] Specifically, the lock core pull rod portion 123 disclosed herein includes a lock core pull rod first feature 123A, which is formed as an arm portion of the lock core pull rod portion 123. Accordingly, the lock core pull rod first feature 123A can be connected to components such as pull wires and driven to rotate by components such as pull wires.

[0213] 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.

[0214] Specifically, Figure 16 In the direction shown, when the lock core rod portion 123 is operated to rotate counterclockwise, the lock core 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 following external opening rod portion 133; of course, at this time, the system can also be unlocked by the above-mentioned internal opening rod portion 104.

[0215] Figure 19 yes Figure 16 A structural diagram from another angle. Figure 20 Schematic diagram of a lock system according to an embodiment of the present disclosure.

[0216] like Figure 16 and Figure 19 As shown, the lock system of the present disclosure further 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.

[0217] 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 component.

[0218] In a specific embodiment, the emergency unlocking portion 131 is formed as a substantially fan-shaped component, and an arc-shaped groove 131A is formed on the emergency unlocking portion 131 , and the center of the arc-shaped groove 131A is located on the E-axis.

[0219] Figure 21 It is a structural schematic diagram of an outward-opening transition rod according to an embodiment of the present disclosure.

[0220] like Figure 21As shown, 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. The cylindrical portion 132A can be slidably and rotatably disposed in the arc-shaped groove 131A. Moreover, 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 closer to the other end of the outward-opening transition rod 132. In other words, compared to 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.

[0221] A spring accommodating portion 132B is provided on the cylindrical portion 132A, and a groove can be formed on the spring accommodating portion 132B. In this case, one end of a spring (such as a coil spring) can be accommodated in the groove, and the other end of the spring can be set on the emergency unlocking portion 131, so that the cylindrical portion 132A can be maintained at the first end of the arc-shaped groove 131A through the reset force provided by the spring.

[0222] 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 the outward-opening pull rod portion 133 unable to drive the operating component 500 to rotate through the outward-opening transition rod portion 132.

[0223] Figure 23 2 is another schematic diagram of the internal structure of a lock system according to one embodiment of the present disclosure.

[0224] In one embodiment of the present disclosure, Figure 23 As shown, 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 .

[0225] In addition, if Figure 23 As shown, the lock system of the present disclosure further includes an outward opening rod portion 133, wherein the outward opening rod portion 133 has an Fth axis, 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 to rotate by the vehicle's outer door handle. In a preferred embodiment, the Fth axis is the same as (coincides with) the third axis.

[0226] At the same time, the outward-opening pull rod portion 133 is formed with a notch. At least a portion of the other end of the outward-opening transition rod portion 132 is located within the notch of the outward-opening pull rod portion 133, and the other end of the outward-opening transition rod portion 132 is able to slide within the notch. In other words, the operating range of the outward-opening transition rod portion 132 is within the depth range of the notch. Regardless of the position of the outward-opening transition rod portion 132, its other end will not disengage from the notch.

[0227] exist Figure 16 In the state shown, the other end of the outward-opening transition rod portion 132 is located in the slot 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.

[0228] 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.

[0229] In the present disclosure, the lock system further includes an intermediate transition rod 134 having 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.

[0230] 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. 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. 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. 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. Therefore, when the intermediate transition rod portion 134 is driven to rotate, it can drive the emergency unlocking portion 131 to rotate.

[0231] In the present disclosure, the intermediate transition rod portion 134 includes an intermediate slot 134C, which 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, which 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 slot 134C, and 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.

[0232] Specifically, Figure 16 Taking the direction shown 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.

[0233] In the present disclosure, the lock cylinder pull rod portion 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.

[0234] Figure 24 2 is a schematic structural diagram of an emergency unlocking portion of a lock system according to an embodiment of the present disclosure. Figure 25 2 is a schematic structural diagram of a safety link portion of a lock system according to an embodiment of the present disclosure.

[0235] like Figure 24 and Figure 25 As shown, 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 in a predetermined direction. When the safety link portion 141 moves, it can drive the emergency unlocking portion 131 to rotate.

[0236] Specifically, if Figure 24As shown, the emergency unlocking portion 131 includes a sliding block 131C that can protrude upward from the plane where the emergency unlocking portion 131 is located. The lower portion of the sliding block 131C is cylindrical and the upper portion is hemispherical, so that 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 flat.

[0237] An accommodating groove 141A is formed at one end of the safety link portion 141, and the sliding block 131C can slide in the accommodating 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.

[0238] Furthermore, by providing the accommodating groove 141A, the sliding block 131C can be located at different positions of the accommodating groove 141A when the emergency unlocking portion 131 rotates, thereby preventing the sliding block 131C from interfering with the safety link portion 141 .

[0239] In one embodiment, the safety link portion 141 can be driven to rotate by the driving claw portion 142. Specifically, the unlocking gear 102 is formed with a driving block 102B, which is located at the other end of the unlocking gear 102 and 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 the two ends of the unlocking gear 102 in the axial direction.

[0240] That is, the driving pawl portion 142 can be driven and rotated by the unlocking gear 102 , and accordingly, the driving pawl portion 142 has an Hth axis, which can be arranged parallel to the rotation axis (ie, the Ath axis) of the unlocking gear 102 .

[0241] 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. Figure 15 As shown, the first rotation direction is clockwise. 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.

[0242] Accordingly, Figure 15 In the direction shown, when the unlocking gear 102 rotates in the second direction, the unlocking gear 102 rotates counterclockwise. Figure 27In the direction shown, the unlocking gear 102 rotates clockwise.

[0243] 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.

[0244] Specifically, if Figure 27 As shown, 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. Figure 27 When the direction shown is counterclockwise, that is, when rotating along the first rotation direction, the driving block 102B can cooperate with the second driving member 142B and apply force to the second driving member 142B, thereby causing the driving claw to rotate clockwise.

[0245] like Figure 28 As shown, 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. The cylindrical protrusion 142C can be slidable in the guide groove 141B of the safety link portion 141, so that when the driving claw portion 142 rotates, it can drive the safety link portion 141 to translate.

[0246] Specifically, Figure 27 In the direction shown, when the driving claw portion 142 rotates counterclockwise, it can drive the safety link portion 141 to the left. On the other hand, when the driving claw portion 142 rotates clockwise, it can drive the safety link portion 141 to the right. Furthermore, when the safety link portion 141 is actuated, it can drive the emergency release portion 131 to rotate. The process of the safety link portion 141 driving the emergency release portion 131 has been described in detail above and will not be repeated here.

[0247] 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 size of the interior 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.

[0248] In this disclosure, Figure 28 As shown, 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 unlocked.

[0249] Refer again Figure 26 and Figure 27 The lock system of the present disclosure further includes a limit member 143, which can be guided by the lock body 100 and moved along a preset direction. In a preferred embodiment, the limit member 143 can be driven by the driving claw portion 142 and move along a preset direction. Specifically, the driving claw portion 142 includes a shift fork 142D, which can cooperate with the limit member 143 and push the limit member 143 to a position where at least a portion of the limit member 143 interferes with the unlocking gear 102, thereby being used to limit the rotation of the unlocking gear 102. For example, the limit member 143 can cooperate with the cam 102A of the unlocking gear 102, thereby preventing the unlocking gear from excessively moving in the second rotation direction through the limit member 143, that is, the unlocking gear 102 cannot rotate one circle in the second rotation direction through the limit member 143.

[0250] In the lock system disclosed herein, a half-locked pawl is not required to limit the position of the lock tongue component, which simplifies the structure of the lock system and reduces the cost of the lock system. Furthermore, the lock system of the present invention has better reliability.

[0251] The lock system disclosed herein 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 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 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.

[0252] More specifically, if Figure 25 As shown, the child safety connecting rod 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 an unlocking rod fourth feature 103D; when the child safety connecting rod portion 151 is in the working position, the limiting component 151A can block the unlocking rod fourth feature 103D, thereby preventing the unlocking rod portion 103 from rotating in the unlocking direction.

[0253] In one embodiment of the present disclosure, a part can be maintained in 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 this disclosure.

[0254] In the present disclosure, the lock body 100 may include a mounting base. In actual use, the lock system can be installed on a vehicle by mounting the mounting base on the vehicle. Preferably, the unlocking motor 101 is arranged on a wall perpendicular to the mounting base, and the super lock push rod motor 121 is arranged on the mounting base or on a surface parallel to the mounting base. Accordingly, the connector 600 is arranged above the lock tongue component 200 and is arranged perpendicular to the mounting base. In this way, the distance between the connector 600 and the two motors can be minimized, saving circuit size.
