[0003] Chinese utility model patent CN217950058U discloses a locking device, which greatly improves the reliability of the locking device by adding a locking device. At the same time, the meshing surface of the lock tongue component and the pawl component can be offset in the unlocking direction, and the electric release device can still achieve electric unlocking even in the case of a large sealing reaction force.

[0004] However, this locking device arranges the two locking positions on one side of the U-shaped groove of the lock tongue component, which makes the lock tongue component larger in size and challenges its strength. In addition, the first operating component of the locking device is separately arranged from the locking component and has different rotation centers, requiring a larger accommodating space.

[0005] Meanwhile, the locking device and the operating component in the prior art have different rotation axes. When the operating component drives the locking device and the pawl component at the same time, the arrangement is difficult, so that the size of the lock body cannot be further reduced.

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.

[0058] 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.

[0059] In the present disclosure, the lock system includes a lock body, a lock tongue component 200 and a pawl component 300 and other components.

[0060] The lock body can be formed as the housing part of the lock system of the present disclosure, for example, it can include a back plate (or bottom plate), a cover body and other structures, for example, the bottom plate in Chinese utility model patent CN217950058U can be used as the lock body of the present disclosure. Accordingly, the bolt component 200 and the pawl component 300 and other components can be installed on the bottom plate and / or the cover body, and the installation method of these components can be implemented in the existing technology, and the present disclosure will not repeat them one by one.

[0061] In some embodiments of the present disclosure, the lock tongue component 200 is rotatably disposed on the lock body, 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.

[0062] 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 (not shown), so that Figure 5 In the state shown, the bolt component 200 can be rotated clockwise from Figure 5 Turn to the unlocked position shown Figure 3 Shown in half-locked position.

[0063] 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.

[0064] 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.

[0065] The following will be combined Figures 1 to 5 To describe the unlocking process of the lock system of the present disclosure.

[0066] 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.

[0067] Figure 7 is a schematic structural diagram of a locking tongue component 200 according to an embodiment of the present disclosure. Figure 8 yes Figure 7 Another angle ( Figure 7 Schematic diagram of the structure (back side perspective).

[0068] 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 located in the U-shaped groove 210; when the lock tongue component 200 is in the unlocked position (such as Figure 5 As shown in FIG. 2 , the lock catch can be released by the lock tongue component 200 , and the lock catch can be disengaged from the U-shaped groove 210 of the lock tongue component 200 .

[0069] 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.

[0070] Fig. 9 is a schematic structural diagram of a pawl component 300 according to an embodiment of the present disclosure. Fig.10 yes Fig. 9 A schematic diagram of the structure from another angle (back side perspective).

[0071] 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, 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 half-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 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 (moving to the second position), Figure 1 In the direction shown, the pawl member 300 can first rotate counterclockwise and release the bolt member 200, and then rotate clockwise and move to the second position to keep the bolt member 200 in the semi-locked position (such as Figure 3shown).

[0072] 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.

[0073] 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 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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 Initially rotating clockwise, during the locking process of the lock system, the pawl component 300 moves from the third position under the action of the reset force, and moves to the second position and the first position in sequence.

[0079] 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.

[0080] 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.

[0081] 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 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 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.

[0082] 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, which is beneficial to the arrangement of the locking device 400 and the operating component 500 of the present disclosure, and reduces the volume of the lock system of the present disclosure, so that the lock system of the present disclosure can be easily applied to different types of vehicles, thereby improving the scope of use of the lock system of the present disclosure.

[0083] 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.

[0084] 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 (back side perspective). 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 (back side perspective).

[0085] Combined with the following Figures 1 to 5 The unlocking process of the lock system of the present disclosure is described again.

[0086] 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.

[0087] refer to Figure 1 and Figure 3 as well as Figures 11 to 14When the operating member 500 is subjected to an external force and rotated counterclockwise (for example, the operating member 500 is subjected to an external force such as an electric actuator via the first feature 501 of the operating portion), the operating member 500 rotates in a direction to release the locking device 400 from locking the pawl member 300, and drives the locking device 400 to rotate in a direction to release the locking of the pawl member 300 ( Figure 1 ), the locking device 400 will leave the first locking position.

[0088] 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 counterclockwise via the second feature 502 of the operating portion (the locking device 400 is driven via the second end portion of the locking device 400 ), and the locking device 400 releases the pawl component 300 .

[0089] 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. In other words, 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.

[0090] 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 lock system 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 lock tongue component 200 (or the lock system) can also be directly rotated from the fully locked position to the open position.

[0091] 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 moves closely to the bolt member 200 under the action of the reset force. Figure 3 The second position shown, thereby maintaining the locking tongue member 200 in the semi-locked position.

[0092] 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.

[0093] 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 or the second position.

[0094] 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.

[0095] 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 .

[0096] 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.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] Combined with the following Figures 1 to 5 To illustrate the locking process of the lock system of the present invention.

[0104] 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.

[0105] In some embodiments of the present disclosure, at least a portion 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 locked position.

[0106] In a preferred embodiment, the locking device 400 can rotate relative to the operating part 500, and the locking device 400 can be closely attached to 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, and 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 closely attached to the second feature 502 of the operating part, and the locking device 400 is located at the second locking position.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] 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.
