Figure 2 yes Figure 1 Schematic diagram from another angle. Figure 3 It is a schematic structural diagram of a lock system according to an embodiment of the present disclosure (the lock tongue component is located in a semi-locked position). Figure 4 yes Figure 3 A schematic diagram of the structure from another angle. Figure 5 It is a schematic structural diagram of a lock system according to an embodiment of the present disclosure (the lock tongue component is in the unlocking position). Figure 6 yes Figure 5 A schematic diagram of the structure from another angle.

[0130] like Figures 1 to 6 As shown, the lock system of the present disclosure can be applied to the hood or door of a motor vehicle, so as to lock the hood or door of the motor vehicle to the vehicle body. For example, a lock buckle can be provided on the vehicle body, and the lock system can hold the lock buckle to achieve locking of the motor vehicle. In the opposite process, when the lock system releases the lock buckle, the hood or door of the motor vehicle can be unlocked.

[0131] In the present disclosure, the lock system includes a lock body 100 , a lock tongue component 200 , a pawl component 300 and other components.

[0132] The lock body 100 can be formed as the housing part of the lock system of the present disclosure, for example, it can include structures such as a back plate and a cover body, and accordingly, components such as a lock tongue component 200 and a pawl component 300 can be installed on the back plate and / or the cover body. The installation method of these components can be implemented in the prior art, and the present disclosure will not repeat them one by one.

[0133] 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.

[0134] 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, so that Figure 5 In the state shown, the bolt component 200 can be rotated clockwise from Figure 1 Turn to the unlocked position shown Figure 3 Shown in half-locked position.

[0135] In some embodiments of the present disclosure, the lock tongue component 200 may also be connected to a structure such as a pull wire of an electric drive mechanism, so as to be driven by the electric drive mechanism to rotate, thereby, the lock system of the present disclosure can achieve electric locking.

[0136] 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.

[0137] In addition, the locking tongue component 200 of the present disclosure can detect its position through a micro switch.

[0138] The following will be combined Figures 1 to 5 The unlocking process is described in the following order.

[0139] During the unlocking process, the bolt component 200 can be unlocked by the reset force (the reset force can be provided by the bolt component reset spring, such as a coil spring). Figure 1 The fully locked position shown is rotated counterclockwise, 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 lock tongue member 200, the lock tongue member 200 can be from Figure 3 Turn to the half-locked position shown Figure 5 to the unlock position shown to complete the unlocking process.

[0140] Figure 7 It is a schematic structural diagram of a locking tongue component according to an embodiment of the present disclosure. Figure 8 yes Figure 7 A schematic diagram of the structure from another angle.

[0141] like Figures 1 to 8As 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.

[0142] 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 The lower side of the U-shaped groove 210 is located at the lower 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.

[0143] Fig. 9 It is a schematic structural diagram of a pawl component according to an embodiment of the present disclosure. Fig.10 yes Fig. 9 A schematic diagram of the structure from another angle.

[0144] In this disclosure, Figures 1 to 5 as well as Fig. 9 and Fig.10 As shown, the pawl component 300 is rotatably disposed on the lock body 100, and the pawl component 300 can be in a first position, a second position and a third position, wherein when the pawl component 300 is in the first position, the pawl component 300 can cooperate with the first feature 201 of the lock tongue and keep the lock tongue component 200 in a fully locked position; when the pawl component 300 is in the second position, the pawl component 300 can cooperate with the second feature 202 of the lock tongue and keep the lock tongue component 200 in a half-locked position; when the pawl component 300 is in the third position, the lock tongue component 200 can be in an unlocked position. In the present disclosure, the first position and the second position can be the same position or different positions. In a preferred embodiment of the present disclosure, the first position and the second position are the same position. 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 at the second position.

[0145] 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.

[0146] Specifically, when the lock system of the present invention is in a fully locked state (such as Figure 1 The lock tongue component 200 is subjected to a force in a simply supported beam structure, and compared with the cantilever beam structure of the conventional lock tongue component 200 in the fully locked position, the strength of the lock tongue component 200 is greatly improved. Accordingly, the lock tongue component 200 of the present disclosure will not be easily damaged by external forces. Moreover, under the premise of meeting the design requirements, since the lock tongue component 200 of the present disclosure is subjected to a force in a simply supported beam structure, its size can be reduced.

[0147] like Figure 1 As shown, in the present disclosure, when the bolt member 200 is in the fully locked position, the bolt first feature 201 and the pawl member 300 are both located on the first side (lower side) of the U-shaped groove 210, and components such as a lock catch (not shown) are located between the rotation axis of the pawl member 300 and the rotation axis of the bolt member 200, thereby, 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.

[0148] In some embodiments of the present disclosure, the contact surface between the pawl component 300 and the first feature 201 of the lock tongue (located on the first arm of the lock tongue component) is formed into a substantially flat surface (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 to prevent the pawl component 300 from leaving the first position.

[0149] 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 operated by the electric actuator or the manual actuator to leave the first position, the pawl member 300 will move along Figure 1In the counterclockwise rotation shown in FIG. 1 , in one case, the pawl component 300 can stop directly at 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.

[0150] 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 Figure 3 The latch member 200 rotates counterclockwise to the third position. Accordingly, when the pawl member 300 is located at the third position, the bolt member 200 can rotate to the unlocking position under the action of the reset force, and the lock system is in an unlocking state.

[0151] 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), as shown in FIG. Figure 5 The pawl component 300 can rotate clockwise under the action of the reset force (the bolt component 200 must first be out of the unlocked position, as described below). During the locking process of the lock system, the bolt component 200 starts to move from the unlocked position, and moves to the half-locked position and the fully locked position in sequence. During the movement of the bolt 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, from Figure 5 Start with clockwise rotation).

[0152] In the present disclosure, during the locking process of the lock system, the pawl component 300 can realize clockwise movement under the action of the reset force, and correspondingly, it can also realize counterclockwise movement under the drive of the lock tongue component 200, so that the pawl component 300 can move to one of the third position, the second position and the first position.

[0153] 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.

[0154] In a preferred embodiment of the present disclosure, the lock system of the present disclosure further includes a locking device 400 and an operating component 500, wherein the locking device 400 is rotatably disposed on the lock body 100 and is used to keep the pawl component 300 at the first position or the second position; the operating component 500 is rotatably disposed on the lock body 100 and is used to drive the locking device 400 to move. Preferably, the operating component 500 and the locking device 400 have the same rotation axis, and on the other hand, the rotation axes of the operating component 500 and the locking device 400 may also be different.

[0155] The present disclosure has redesigned the matching method and matching structure of the locking device 400 and the operating component 500, forming an important inventive content of the present disclosure, and configured the two to have the same rotation axis, in other words, to have the same rotation 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.

[0156] 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.

[0157] Fig.11 is a schematic structural diagram of an operating component according to an embodiment of the present disclosure. Fig.12 yes Fig.11 A schematic diagram of the structure from another angle. Fig.13 It is a schematic structural diagram of a locking device according to one embodiment of the present disclosure. Fig.14 yes Fig.13 A schematic diagram of the structure from another angle.

[0158] Combined with the following Figures 1 to 5 The unlocking process of the lock system of the present disclosure is described again.

[0159] 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 member 300 in a position engaged with the first feature 201 of the locking tongue. At this time, the pawl member 300 is in the first position and the locking device 400 is in the first locked position.

[0160] refer to Figure 1 and Figure 3 as well as Figures 11 to 14When 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 part), the operating component 500 rotates in the direction of releasing the lock of the pawl component 300 by the locking device 400, and drives the locking device 400 to rotate in the direction of releasing the lock of the pawl component 300 (counterclockwise in the figure), and the locking device 400 will leave the first locking position.

[0161] 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 is rotated counterclockwise (refer to Figure 1 ), the locking device 400 is driven to rotate counterclockwise (via the second end of the locking device 400 ) via the second feature 502 of the operating portion, and the locking device 400 releases the pawl component 300 .

[0162] 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.

[0163] In one embodiment, when the first position and the second position of the pawl component 300 are the same position, the unlocking process of the locking device may not pass through the second position, that is, the operating component 500 can directly drive the pawl component 300 to the third position, and accordingly, the locking device can also be directly rotated from the fully locked position to the open position.

[0164] Accordingly, when the operating member 500 rotates counterclockwise and then clockwise, the operating member 500 can release the pawl member 300. Accordingly, when the bolt member 200 leaves the fully locked position, the pawl member 300 will be pressed against the bolt 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 locking tongue member 200 in the semi-locked position.

[0165] Lock system in Figure 3 In the semi-locked state shown in FIG. 1 , when the operating member 500 is driven again and rotated counterclockwise again, it can drive the pawl member 300 to rotate from Figure 3 The second position shown moves to Figure 5In the third position shown, the bolt member 200 moves to the position as shown in FIG. Figure 5 The unlocked position shown in the figure realizes the unlocking of the lock system, and the lock system reaches the unlocked state.

[0166] 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.

[0167] In a preferred embodiment of the present disclosure, the operating part 500 is provided with a fourth operating feature 504. When the lock system is in a semi-locked state (the lock tongue part 200 is in a semi-locked position, and the pawl part 300 is in the second position), the first end of the pawl part 300 is held by the first end of the locking device 400, so that the pawl part 300 is stably held in the second position, and the fourth operating feature 504 holds the second arm of the lock tongue part 200 (blocking the lock tongue part 200 from continuing to rotate clockwise, such as Figure 3 As shown in FIG. 1 ), the bolt member 200 is stably held 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 arranged away from the bolt second feature 202) cooperates with the operating portion fourth feature 504, so that the bolt member 200 is held in the semi-locked position by the operating portion fourth feature 504 and the first end of the pawl member 300.

[0168] 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 .

[0169] Lock system in Figure 3 In the semi-locked state shown, when the first feature 501 of the operating part is driven, the operating part 500 rotates counterclockwise, and 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 component 300. The pawl component 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 component 200. The lock tongue component 200 moves to the unlocked position under the action of the reset force, thereby realizing the unlocking of the lock system, and the lock system reaches the unlocked state, as shown in FIG. Figure 5 shown.

[0170] 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 reset spring (not shown, such as a coil spring), and the fourth feature 504 of the operating part will abut against the third feature 203 of the lock tongue, thereby jointly with the first end of the pawl 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.

[0171] 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 the pawl component 300 is driven by the third feature 503 of the operating part and rotates 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 lock 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.

[0172] 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.

[0173] In the preferred embodiment of the present disclosure, refer to the attached Figures 1 to 5 , the first feature 501 of the operating part described above in the present disclosure is configured on the third feature 503 of the operating part described above in the present disclosure.

[0174] In some embodiments of the present disclosure, the third feature 503 of the operating part is in the form of an operating handle, and the first feature 501 of the operating part is in the form of a through hole. Inspired by the technical solution of the present disclosure, adjustments made by those skilled in the art to the structure or shape of the third feature 503 of the operating part and the first feature 501 of the operating part all fall within the protection scope of the present disclosure.

[0175] In a preferred embodiment of the present disclosure, the line between the third operating portion feature 503 and the fourth operating portion feature 504 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.

[0176] In the present disclosure, when the pawl component 300 leaves the first position or the second position, it can leave the movement path range of the lock tongue component, so that the lock tongue component can rotate in the unlocking direction.

[0177] Combined with the following Figures 1 to 5 To illustrate the locking process of the lock system of the present invention.

[0178] During the locking process of the lock system, the bolt component 200 is driven by components such as a lock catch to move 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 may 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, when the lock system moves 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.

[0179] In some embodiments of the present disclosure, at least part of the outer surface of the third arm (preferably, the third arm is formed by the transverse extension of the second arm) of the bolt member 200 is formed as a guide surface 204. When the bolt member 200 moves from the unlocked position to the semi-locked position, the fourth feature 504 of the operating portion moves in a manner of being close to the guide surface 204 of the bolt member 200. More preferably, the guide surface is configured so that when the pawl member 300 is located at the second position, the locking device 400 moves to the second position.

[0180] In a preferred embodiment, the locking device 400 can rotate relative to the operating part 500, and the locking device 400 can be in close contact with the second feature 502 of the operating part under the action of the reset force provided by the reset spring, etc.; during the locking process, the lock tongue part 200 can drive the pawl part 300 to leave the third position and further rotate clockwise, at which time, the pawl part 300 can push the locking device 400 to rotate counterclockwise and generate relative movement with the operating part 500, at which time the locking device 400 will not move to the second locking position. Then, when the lock tongue part 200 moves to the semi-locked position, the pawl part 300 rotates counterclockwise under the action of the reset force and moves to the second position, and accordingly, the locking device 400 can rotate clockwise under the action of the reset force and move to a position in close contact with the second feature 502 of the operating part, at which time the locking device 400 is in the second locking position.

[0181] 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.

[0182] 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, for example, a lock buckle. During the movement of the lock tongue component 200 from the semi-locked position to the fully locked position, the lock tongue component 200 first directly drives the operating component 500 (the lock tongue component 200 drives the operating component 500 via the fourth feature 504 of the operating part) to rotate counterclockwise, and the second feature 502 of the operating part drives the second end of the locking device 400, so that the locking device 400 and the operating component 500 rotate counterclockwise synchronously, and the locking device 400 disengages from the second locking position, releasing the lock on the pawl component 300, and the pawl component 300 is driven by the third feature 503 of the operating part to rotate counterclockwise, and the first end of the pawl component 300 disengages from the second feature 202 of the lock tongue, so that the lock tongue component 200 can continue to move toward the fully locked position under the drive of the lock buckle and other components.

[0183] After the end of the first arm of the bolt member 200 is out of contact with the side 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. 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 directly opposite to 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, such as Figure 1 shown.

[0184] In the present disclosure, when the lock tongue component 200 moves from the semi-locked position to the fully locked position, the pawl component 300 first moves in the direction away from the first position (rotates counterclockwise), and then moves in the direction close to the first position (rotates clockwise), so that the lock tongue component 200 is first released from the semi-locked position and then locked again in the fully locked position.

[0185] Fig.15 It is a schematic diagram of the internal structure of a lock system according to one embodiment of the present disclosure.

[0186] like Fig.15 As shown, the operating component 500 of the present disclosure can be driven to rotate by the unlocking motor 101, thereby realizing the unlocking of the lock system. Specifically, the unlocking motor 101 can be arranged on the lock body 100, and can be connected to the unlocking gear 102 in a transmission manner. In a specific embodiment, the unlocking gear 102 is rotatably arranged on the lock body 100, and has an A-th axis. Preferably, the A-th axis of the unlocking gear 102 can be perpendicular or substantially perpendicular to the third axis of the operating component 500, thereby enabling the lock system of the present disclosure to be conveniently arranged in the door and other components of a motor vehicle.

[0187] In a preferred embodiment, the output shaft of the unlocking motor 101 is formed as a worm, and the worm can mesh with the teeth on the outer periphery of the unlocking gear 102. In this case, the unlocking gear 102 can also be called an unlocking worm wheel. In the present disclosure, the worm can be a three-head worm, so that the worm and the unlocking gear 102 will not be self-locking. That is to say, in the worm and worm gear transmission structure of the present disclosure, the unlocking gear 102 can be driven to rotate by the rotation of the worm, and conversely, when the unlocking gear 102 is driven to rotate, the worm can also be driven to rotate.

[0188] A cam 102A is formed at one end face of the unlocking gear 102 in the axial direction, and the cam surface of the cam 102A is the outer peripheral surface of the cam 102A. When the unlocking gear 102 is driven to rotate, the outer peripheral surface of the cam 102A can drive the unlocking rod 103 to rotate, and the unlocking rod 103 is in contact with the operating component 500 to unlock the lock system.

[0189] In a specific embodiment, the unlocking lever 103 is rotatably disposed on the lock body 100, and the unlocking lever 103 has a B-th axis, and the A-th axis is disposed parallel to the B-th axis and spaced a certain distance apart.

[0190] In the present disclosure, the unlocking rod portion 103 may include an unlocking rod first feature 103A, wherein the unlocking rod first feature 103A may be formed as an arm portion of the unlocking rod portion 103, so that when the unlocking rod first feature 103A contacts the surface of the cam 102A and is driven by the cam 102A, the unlocking rod portion 103 can be applied an unlocking torque by the cam 102A.

[0191] 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.

[0192] The lock system of the present invention can also be manually unlocked. Specifically, the lock system of the present invention also includes an inner opening rod portion 104, which is rotatably arranged on the lock body 100, and correspondingly, the inner opening rod portion 104 has a C-th axis, wherein the C-th axis, the A-th axis and the B-th axis are all arranged in parallel and spaced apart by a preset distance.

[0193] More specifically, the inner opening tie rod portion 104 has an inner opening tie rod first feature 104A, and the inner opening tie rod first feature 104A can be formed as an arm portion of the inner opening tie rod portion 104, so that an inner opening tie wire can be set on the inner opening tie rod first feature 104A, and when an external force is applied to the inner opening tie rod portion through the inner opening tie wire, the inner opening tie rod portion 104 can be rotated. For example, when the lock system is opened, the inner opening tie rod portion 104 can be rotated. Figure 4 In addition, when the external force applied by the inner opening draw wire lock is removed, the inner opening draw rod portion 104 can rotate counterclockwise under the effect of the restoring force of a resetting element such as a coil spring, and be maintained at a preset initial position.

[0194] The inner opening tie rod portion 104 further includes an inner opening tie rod second feature 104B, and the inner opening tie rod second feature 104B is also formed as an arm portion of the inner opening tie rod portion 104, so that the inner opening tie rod portion 104 can drive the unlocking lever portion 103 to rotate through the cooperation of the inner opening tie rod second feature 104B and the unlocking lever portion 103. More preferably, the unlocking lever portion 103 includes an unlocking lever third feature 103C, and accordingly, the inner opening tie rod second feature 104B can cooperate with the unlocking lever third feature 103C.

[0195] In one embodiment, Fig.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.

[0196] Fig.16 is another schematic diagram of the internal structure of a lock system according to an embodiment of the present disclosure.

[0197] like Fig.15 and Fig.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.

[0198] Specifically, Fig.15 In the direction shown, the super lock push rod portion 105 can be driven and moved to the left, and can be in Fig.16 The position shown in the figure, 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.

[0199] 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.

[0200] On the other hand, when the super lock push rod 105 pushes the unlocking rod 103 to rotate, the super lock push rod 105 can be limited to a position, so that the unlocking rod 103 cannot be driven to rotate, that is, at this time, even if the unlocking motor 101 is powered, the unlocking motor 101 cannot push the unlocking rod 103 to rotate, and correspondingly, unlocking cannot be achieved. In other words, at this time, only by first removing the restriction of the super lock push rod 105 to the unlocking rod 103, the lock system can be opened. On the other hand, when the unlocking motor 101 is powered on and drives the unlocking rod 103 to rotate, the unlocking rod 103 can push the super lock push rod 105 to move, and at this time, the super lock push rod 105 can move to the right, and correspondingly, the super lock push rod 105 can only realize the function of preventing manual unlocking, and it cannot prevent electric unlocking. In other words, no matter where the super lock push rod 105 is, the electric unlocking function of the lock system is always effective.

[0201] Fig.17 is another schematic diagram of the internal structure of a lock system according to an embodiment of the present disclosure.

[0202] like Fig.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 powered on and rotated, and a worm is provided on the output shaft of the super lock push rod motor 121, or in other words, the output shaft of the super lock push rod motor 121 is formed as a worm, and the worm can mesh with the teeth of the outer periphery of the super lock push rod gear 122, and the super lock push rod gear 122 can also be referred to as a super lock push rod worm gear. In the present disclosure, the worm can adopt a single-head worm or a multi-head worm, which will not be repeated one by one here.

[0203] Fig.18 It is a schematic structural diagram of a super lock push rod gear according to an embodiment of the present disclosure.

[0204] like Fig.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.

[0205] 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.

[0206] At this time, when the super lock push rod motor 121 rotates in the forward or reverse direction, the super lock push rod portion 105 can be driven to move left or right. On the other hand, the worm of the present disclosure and the super lock push rod gear 122 will not self-lock, that is, in the present disclosure, when the super lock push rod motor 121 rotates, the super lock push rod gear 122 can be driven to rotate, and in the opposite working process, when the super lock push rod gear 122 is driven to rotate, it can also drive the worm to rotate.

[0207] In the present disclosure, a limiting portion 122B is also formed on an axial surface of the first end of the super lock push rod gear 122. The limiting portion 122B can cooperate with a limiting structure 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 gear.

[0208] Refer to Fig.16 The lock system of the present invention also includes a lock core rod portion 123, which has a Dth axis, wherein the Dth axis can be arranged 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.

[0209] Specifically, the lock core rod portion 123 of the present disclosure includes a lock core rod first feature 123A, which is formed as an arm portion of the lock core rod portion 123. Accordingly, the lock core rod first feature 123A can be connected to components such as pull wires and driven to rotate by components such as pull wires.

[0210] 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.

[0211] Specifically, Fig.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 rightward, thereby releasing the unlocking rod portion 103, whereby the lock system is in a state that can be opened, and accordingly, the lock system can be unlocked by the external opening rod portion 133 described below; of course, at this time, the system can also be unlocked by the above-mentioned internal opening rod portion 104.

[0212] Fig.19 yes Fig.16 A schematic diagram of the structure from another angle. Fig. 20 It is a structural schematic diagram of a lock system according to one embodiment of the present disclosure.

[0213] like Fig.16 and Fig.19 As shown, the lock system of the present invention 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 configured to rotate relative to the lock body 100. In a preferred embodiment, the E-th axis can be parallel to the first axis.

[0214] At least a portion of the emergency unlocking portion 131 can pass through the through hole of the lock body 100 , and the emergency unlocking portion 131 can be driven to rotate by a screwdriver or other components.

[0215] 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.

[0216] Fig.21 It is a schematic structural diagram of an outwardly opening transition rod portion according to an embodiment of the present disclosure.

[0217] like Fig.21As shown, the lock system of the present disclosure also includes an outward-opening transition rod 132, one end of which is provided with a cylindrical portion 132A, and the cylindrical portion 132A can be slidably and rotatably arranged in the arc-shaped groove 131A, and the arc-shaped groove 131A includes a first end and a second end, wherein the first end of the arc-shaped groove 131A is an end away from the other end of the outward-opening transition rod 132, and correspondingly, the second end of the arc-shaped groove 131A is an end close to the other end of the outward-opening transition rod 132. In other words, compared with the first end of the arc-shaped groove 131A, the second end of the arc-shaped groove 131A is closer to the other end of the outward-opening transition rod 132.

[0218] The cylindrical portion 132A is provided with a spring accommodating portion 132B, and a groove may be formed on the spring accommodating portion 132B. In this case, one end of a spring (e.g., a coil spring) may be accommodated in the groove, and the other end of the spring may be arranged on the emergency unlocking portion 131, so that the cylindrical portion 132A may be maintained at the first end of the arc-shaped groove 131A through the reset force provided by the spring.

[0219] In addition, the outward-opening transition rod portion 132 also includes an outward-opening transition rod first feature 132C, and the outward-opening transition rod first feature 132C can be formed as a limiting structure. Accordingly, the super lock push rod portion 105 includes a protruding feature. When the super lock push rod portion 105 is in the working position, it can limit the position of the outward-opening transition rod portion 132 and make it impossible for the outward-opening pull rod portion 133 to drive the operating component 500 to rotate through the outward-opening transition rod portion 132.

[0220] Fig.23 is another schematic diagram of the internal structure of a lock system according to an embodiment of the present disclosure.

[0221] In one embodiment of the present disclosure, Fig.23 As shown, the operating component 500 has an end portion along the circumferential direction, and the other end of the outward transition rod portion 132 can selectively cooperate with the operating component 500 through the rotation of the emergency unlocking portion 131 .

[0222] In addition, if Fig.23 As shown, the lock system of the present disclosure further includes an outward opening pull rod 133, wherein the outward opening pull rod 133 has a third axis, that is, the outward opening pull rod 133 can be driven to rotate. In a specific embodiment, the outward opening pull rod 133 can be driven by an outer door handle of the vehicle to achieve rotation. In a preferred embodiment, the third axis is the same as (coincides with) the third axis.

[0223] At the same time, the outer opening tie rod portion 133 is formed with a notch, and at least part of the other end of the outer opening transition rod portion 132 is located in the notch of the outer opening tie rod portion 133, and the other end of the outer opening transition rod portion 132 can slide in the notch. In other words, the running stroke of the outer opening transition rod portion 132 is within the depth range of the notch, and no matter where the outer opening transition rod portion 132 is located, its other end will not be separated from the notch.

[0224] exist Fig.16 In the state shown, the other end of the outward-opening transition rod portion 132 is located in the groove of the outward-opening pull rod portion 133 and does not cooperate with the end of the operating component 500. At this time, when the outward-opening pull rod portion 133 is driven to rotate clockwise, it will not drive the operating component 500 to rotate, and accordingly, the locking system will not be unlocked.

[0225] 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.

[0226] In the present disclosure, the lock system further includes an intermediate transition rod 134, and the intermediate transition rod 134 has a Gth axis, that is, the intermediate transition rod 134 can rotate relative to the lock body 100, wherein the Gth axis can be parallel to the first axis.

[0227] The intermediate transition rod portion 134 is used to drive the emergency unlocking portion 131 to rotate. Specifically, the intermediate transition rod portion 134 includes an intermediate transition rod first feature 134A, and the intermediate transition rod first feature 134A can be formed as a wall portion of the intermediate transition rod portion 134, and a slide groove 134B with an opening is formed on the intermediate transition rod first feature 134A, and the extension direction of the slide groove 134B is toward the Gth axis of the intermediate transition rod portion 134, that is, the slide groove 134B extends along the radial direction of the intermediate transition rod portion 134, and the outer peripheral surface of the emergency unlocking portion 131 is provided with a slide column 131B, and the slide column 131B can be slidably arranged in the slide groove 134B, thereby, when the intermediate transition rod portion 134 is driven to rotate, it can drive the emergency unlocking portion 131 to rotate.

[0228] In the present disclosure, the intermediate transition rod portion 134 includes an intermediate groove 134C, and the intermediate groove 134C includes a first side wall and a second side wall along the circumference of the intermediate transition rod portion 134, wherein the lock core pull rod portion 123 includes a lock core pull rod third feature 123C, and the lock core pull rod third feature 123C is formed as a wall portion of the lock core pull rod portion 123, and the lock core pull rod third feature 123C is located in the intermediate groove 134C, when the lock core pull rod portion 123 rotates, it can contact the above-mentioned first side wall or the second side wall, thereby pushing the intermediate transition rod portion 134 to rotate in different directions.

[0229] Specifically, Fig.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.

[0230] In the present disclosure, the lock core pull rod 123 can rotate clockwise under the action of a reset element such as a torsion spring, and accordingly, it can drive the emergency unlocking portion 131 to rotate clockwise. Moreover, the emergency unlocking portion 131 can also rotate counterclockwise under the action of a reset element such as a torsion spring.

[0231] Fig.24 is a schematic structural diagram of an emergency unlocking portion of a lock system according to an embodiment of the present disclosure. Fig.25 It is a schematic structural diagram of a safety link portion of a lock system according to an embodiment of the present disclosure.

[0232] like Fig.24 and Fig.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 along a preset direction, and when the safety link portion 141 moves, it can push the emergency unlocking portion 131 to rotate.

[0233] Specifically, if Fig.24As shown, the emergency unlocking portion 131 includes a sliding block 131C, which can protrude upward from the plane where the emergency unlocking portion 131 is located, and the lower part of the sliding block 131C is cylindrical, and the upper part is a hemispherical body, and the axis of the sliding block 131C can be parallel to the rotation axis of the emergency unlocking portion 131. In a preferred embodiment, the surface of the sliding block 131C close to the safety link portion 141 can be a plane.

[0234] One end of the safety link portion 141 is formed with a receiving groove 141A, and the sliding block 131C can slide in the receiving groove 141A, so that when the safety link portion 141 moves in a direction perpendicular to the rotation axis of the emergency unlocking portion 131, it can apply a thrust to the sliding block 131C, thereby causing the emergency unlocking portion 131 to rotate.

[0235] Furthermore, by providing the accommodating groove 141A, when the emergency unlocking portion 131 rotates, the sliding block 131C can be located at different positions of the accommodating groove 141A, so that the sliding block 131C will not interfere with the safety link portion 141 .

[0236] In one embodiment, the safety link portion 141 can be driven to rotate by the driving claw portion 142. Specifically, a driving block 102B is formed on the unlocking gear 102, and the driving block 102B is located at the other end of the unlocking gear 102 and is spaced apart from the rotation axis of the unlocking gear 102. In other words, the driving block 102B and the cam 102A are respectively located at two ends of the unlocking gear 102 in the axial direction.

[0237] That is, the driving claw portion 142 can be driven and rotated by the unlocking gear 102 , and accordingly, the driving claw portion 142 has an Hth axis, which can be arranged in parallel with the rotation axis (ie, the Ath axis) of the unlocking gear 102 .

[0238] 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. Fig.15 As shown in the direction, 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.

[0239] Accordingly, Fig.15 In the direction shown, when the unlocking gear 102 rotates in the second direction, the unlocking gear 102 rotates counterclockwise. Fig. 27In the direction shown, the unlocking gear 102 rotates clockwise.

[0240] 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.

[0241] Specifically, if Fig. 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. Fig. 27 When the driving block 102B rotates counterclockwise as shown, that is, rotates 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, so that the driving claw portion rotates clockwise.

[0242] like Fig.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, and the cylindrical protrusion 142C can slide in the guide groove 141B of the safety link portion 141, so that when the driving claw portion 142 rotates, the safety link portion 141 can be driven to translate.

[0243] Specifically, Fig. 27 In the direction shown, when the driving claw 142 rotates counterclockwise, it can drive the safety link 141 to move to the left; on the other hand, when the driving claw 142 rotates clockwise, it can drive the safety link 141 to move to the right. Further, when the safety link 141 moves, it can drive the emergency unlocking part 131 to rotate. The driving process of the safety link 141 on the emergency unlocking part 131 has been described in detail above, and will not be repeated here.

[0244] In a preferred embodiment, the first driving member 142A and the second driving member 142B can have substantially the same structure, and hooks are formed at the ends of the first driving member 142A and the second driving member 142B, thereby making the size of the opening of the working space smaller than the internal size of the working space, so that when the unlocking gear 102 drives the driving claw portion 142 to move, the driving claw portion 142 can have a larger movement stroke.

[0245] In this disclosure, Fig.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 unlocking.

[0246] Refer to Fig.26 and Fig. 27 The lock system of the present disclosure further includes a limiter 143, which can be guided by the lock body 100 and move along a preset direction. In a preferred embodiment, the limiter 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 limiter 143 and push the limiter 143 to a position where at least part of the limiter 143 interferes with the unlocking gear 102, and thus can be used to limit the rotation of the unlocking gear 102. For example, the limiter 143 can cooperate with the cam 102A of the unlocking gear 102, thereby blocking the excessive movement of the unlocking gear in the second rotation direction through the limiter 143, that is, through the limiter 143, the unlocking gear 102 cannot rotate one circle in the second rotation direction.

[0247] In the lock system disclosed in the present invention, the half-locking pawl is not required to limit the lock tongue component, which simplifies the structure of the lock system and reduces the cost of the lock system. In addition, the lock system of the present invention has better reliability.

[0248] The lock system of the present invention also includes a child safety link 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 151 is located in the working position, it can prevent the unlocking rod 131 from rotating in the unlocking direction, and correspondingly, when the child safety link 151 is located in the non-working position, it can allow the unlocking rod 131 to rotate in the unlocking direction, at which time the system can be unlocked.

[0249] More specifically, if Fig.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 a fourth feature 103D of the unlocking rod; when the child safety connecting rod portion 151 is in the working position, the limiting component 151A can block the fourth feature 103D of the unlocking rod, thereby preventing the unlocking rod portion 103 from rotating in the unlocking direction.

[0250] In one embodiment of the present disclosure, the parts can be maintained in a preset position or reset to a preset position by structures such as a return spring or a damper. These structures can be implemented using structures in the prior art and will not be described in detail in the present disclosure.

[0251] In the present disclosure, the lock body 100 may include a mounting base plate. In actual use, the lock system may be installed on a vehicle by mounting the mounting base plate on the vehicle. Preferably, the unlocking motor 101 is arranged on a wall perpendicular to the mounting base plate, and the super lock push rod motor 121 is arranged on the mounting base plate or on a surface parallel to the mounting base plate. Accordingly, the connector 600 is arranged at a position above the lock tongue component 200 and is arranged perpendicular to the mounting base plate, so that the distance between the connector 600 and the two motors can be minimized, saving the size of the circuit.
