Detailed Implementation

[0029] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0030] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] Unless otherwise stated, the exemplary implementations / embodiments shown are to be understood as providing exemplary features of various details that provide ways in which the technical concepts of this disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.

[0032] Figure 1 This is a schematic diagram of a locking system according to one embodiment of the present disclosure. Figure 2 This is a schematic diagram of the internal structure of a lock system according to one embodiment of the present disclosure.

[0033] like Figure 1 and Figure 2 As shown, the lock system disclosed herein may include components such as lock body 100, bolt component 200, and main pawl 300.

[0034] The lock body 100 can be formed as the housing part of the lock system of this disclosure. For example, it may include structures such as a back plate and a cover. Accordingly, components such as the bolt member 200 and the main pawl 300 can be rotatably mounted on the back plate and / or the cover.

[0035] In some embodiments of this disclosure, the latch member 200 is rotatably disposed on the lock body 100, and the axis of rotation of the latch member 200 relative to the lock body 100 is a first axis. The latch member 200 may include at least a locked position and an unlocked position, and when the latch member 200 rotates, the latch member 200 may move between the locked position and the unlocked position.

[0036] In one specific embodiment, the locking tongue component 200 of this disclosure includes a locked position, a partially locked position, and an unlocked position. Figure 4 As shown, the latch component 200 is in the locked position, and the locking system is in the locked state. Figure 4 As shown in the diagram, when the latch component 200 rotates counterclockwise, it can move sequentially from the locked position to the half-locked position and then to the unlocked position. When the latch component 200 is in the half-locked position, the lock system is in a half-locked state. When the latch component 200 is in the unlocked position, the lock system is in an unlocked state. When the lock system is in the unlocked state, the latch component 200 can release the latch (lock pin or striker), thereby unlocking the lock system.

[0037] In this disclosure, Figure 4 As shown, the unlocking process of the latch component 200 can be achieved by the restoring force provided by the return spring. Those skilled in the art will understand that when the locking system of this disclosure is installed on a side door of a vehicle and the side door is closed, a striker mounted on the vehicle body will push the latch component 200 to rotate clockwise, thereby enabling the locking system to lock.

[0038] The main pawl 300 of this disclosure is rotatably disposed on the lock body 100. Specifically, the main pawl 300 is configured to rotate about a second axis, with the first axis located on a first side of the second axis. In other words, the first axis and the second axis of this disclosure are arranged parallel to each other and do not coincide. Based on this, it can be considered that the first axis is located on a first side of the second axis. Figure 4 In the indicated direction, the first axis is located to the left of the second axis.

[0039] The main pawl 300 of this disclosure has a first position and a second position. Accordingly, due to the rotation of the main pawl 300, it can also reciprocate between the first position and the second position. When the main pawl 300 is in the first position, it is used to restrict the locking tongue member 200 to the locked position; when the main pawl 300 is in the second position, the main pawl 300 releases the locking tongue member 200, at which time the locking tongue member 200 can move from the locked position to at least the half-locked position under the action of the return force of the return spring.

[0040] The latch member 200 disclosed herein includes a first force-applying surface, which is a portion of the peripheral surface of the latch member 200. In one specific embodiment, the latch member 200 has a stepped portion, the stepped surface of which is the aforementioned first force-applying surface.

[0041] Correspondingly, the main pawl 300 of this disclosure includes a first force-receiving surface. When the main pawl 300 restricts the locking tongue member 200 to the locked position, the first force-applying surface of the locking tongue member 200 applies a first thrust to the first force-receiving surface of the main pawl 300. The direction of the first thrust is toward the second side of the second axis, wherein the first side and the second side of the second axis are opposite sides of the second axis.

[0042] Specifically, such as Figure 4 As shown, the first thrust is directed towards the right side of the second axis, thereby enabling the main pawl 300 to rotate counterclockwise. In other words, the main pawl 300 has a tendency to move from the first position to the second position. Therefore, when unlocking, the lock system of this disclosure requires only a small force to drive the main pawl 300 from the first position to the second position. Moreover, the greater the first thrust applied by the bolt member 200 to the main pawl 300, the smaller the force required to drive the main pawl 300 from the first position to the second position. Accordingly, the lock system of this disclosure can be easily unlocked, effectively solving the problem in the prior art where the lock system is difficult to unlock when the bolt member 200 applies a large force to the main pawl 300.

[0043] like Figure 2 and Figure 4 As shown, the locking system of this disclosure also includes a secondary pawl 400, which is configured to rotate about a third axis. The secondary pawl 400 is used to restrict the latch component 200 to a semi-locked position. Thus, the locking system of this disclosure has more functions and can be adapted to different vehicle models accordingly.

[0044] In this disclosure, the third axis, the first axis, and the second axis are all arranged in parallel and do not overlap with each other. In other words, the secondary pawl 400 of this disclosure rotates about a separate axis, and the secondary pawl 400 and the primary pawl 300 are located in different planes or at different heights. Accordingly, the primary pawl 300 and the secondary pawl 400 can rotate independently without affecting each other.

[0045] In one specific embodiment, the latch component 200 is provided with a protrusion 210, and the secondary pawl 400 is in pressure contact with the protrusion 210, thereby restricting the latch component 200 to a half-locked position.

[0046] Figure 3 This is a schematic diagram of a locking system in a locked state according to one embodiment of the present disclosure. Figure 4 This is a structural schematic diagram of a locking system in a locked state according to one embodiment of the present disclosure from another angle. Figure 5 This is a schematic diagram of a locking system in a semi-locked state according to one embodiment of the present disclosure. Figure 6This is a schematic diagram of a lock system in an unlocked state according to one embodiment of the present disclosure.

[0047] like Figures 3 to 6 As shown, in use, the lock system of this disclosure can be driven to rotate the secondary pawl 400 once and then reset. The secondary pawl 400 will drive the main pawl 300 to move from the first position to the second position. At this time, the bolt member 200 will rotate from the locked position to the unlocked position. Since the secondary pawl 400 has reset after driving the main pawl 300 to rotate, the protrusion 210 will be stopped by the secondary pawl 400, and the bolt member 200 will be in a half-locked position. Correspondingly, the lock system is also in a half-locked state.

[0048] When the lock system is in a half-locked state, the secondary pawl 400 can be driven to rotate again, so that the secondary pawl 400 releases the protrusion 210, thereby allowing the bolt component 200 to rotate from the half-locked position to the unlocked position, at which point the lock system will be in an unlocked state.

[0049] In another operating mode, the secondary pawl 400 may remain in the same position after driving the primary pawl 300 to move, instead of resetting. In this case, the secondary pawl 400 will not be able to engage with the protrusion 210, thus stopping the latch component 200 in the half-locked position. In this opening mode, the latch component 200 will rotate directly from the locked position to the unlocked position without remaining in the half-locked position.

[0050] When the lock system of this disclosure is locked, the bolt (or latch) or other components can be used to rotate the latch component 200, causing it to rotate from the unlocked position to the locked position. Of course, the latch component 200 may or may not remain in the semi-locked position during the rotation from the unlocked position to the locked position; this disclosure does not limit this.

[0051] In this disclosure, the protrusion 210 includes a second force-applying surface, and the secondary pawl 400 includes a second force-receiving surface. When the secondary pawl 400 restricts the locking tongue member 200 to a semi-locked position, the second force-applying surface applies a second thrust to the second force-receiving surface. The direction of the second thrust is toward the third axis, or the direction of the second thrust is toward the region between the first axis and the third axis.

[0052] In other words, when the lock system of this disclosure is in use, and the latch component 200 is held in the semi-locked position by the secondary pawl 400, the latch component 200 will not apply a force to the secondary pawl 400 to drive the secondary pawl 400 to rotate in the unlocking direction, thereby the latch component 200 of this disclosure can be stably held in the semi-locked position.

[0053] In other words, under normal circumstances, when the latch member 200 is in the fully locked position, the striker applies force to the latch member 200, causing it to tend to rotate towards the unlocked position. In particular, when the door deforms due to a vehicle impact, the force applied by the striker to the latch member 200 may further increase. In this case, the first thrust setting makes the locking system of this disclosure easier to unlock.

[0054] When the latch component 200 rotates to a preset angle, that is, when the latch component 200 rotates from the locked position to the half-locked position, the force applied by the striker to the latch component 200 will decrease or even disappear. At this time, in the half-locked position, the latch component 200 does not need to apply a force to the secondary pawl 400 that can drive the secondary pawl 400 to rotate in the unlocking direction. Accordingly, the key consideration is that the secondary pawl 400 can stably keep the latch component 200 in the half-locked position to improve the security of the lock system.

[0055] Figure 7 This is a schematic diagram of the driving principle of the main pawl according to one embodiment of the present disclosure. Figure 8 yes Figure 7 A schematic diagram from another angle.

[0056] like Figure 7 and Figure 8 As shown, in this disclosure, the locking system also includes an auxiliary pawl 500, which is used to restrain the main pawl 300 in a first position. Therefore, in the locking system of this disclosure, the main pawl 300 can be stably held in the first position, thereby preventing accidental unlocking of the locking system and improving its security.

[0057] In other words, since the latch component 200 of this disclosure can apply a first thrust to the main pawl 300 and cause the main pawl 300 to have a tendency to move from the first position to the second position, it is necessary to limit the position of the main pawl 300 by the auxiliary pawl 500, thereby preventing the main pawl 300 from being driven and rotated by the latch component 200 to open the lock system.

[0058] See again Figure 7 and Figure 8 The auxiliary pawl 500 of this disclosure is configured to rotate about a fourth axis, and the secondary pawl 400 can drive the auxiliary pawl 500 to rotate, and drive the main pawl 300 to move from the first position to the second position through the auxiliary pawl 500.

[0059] Therefore, the lock system of this disclosure can be unlocked by driving the rotation of the secondary pawl 400. Thus, the secondary pawl 400 of this disclosure can not only unlock the locked position of the bolt member 200 but also unlock the half-locked position of the bolt member 200. Accordingly, the lock system of this disclosure can have a relatively simple unlocking mechanism (not shown in the figure), and the lock system also has fewer parts, which reduces the manufacturing cost of the lock system and improves the service life of the lock system.

[0060] In a preferred embodiment, the main pawl 300 includes a notch 310 with a stop surface at the opening of the notch 310, and the auxiliary pawl 500 can engage with the stop surface to restrict the main pawl 300 to a first position.

[0061] Specifically, such as Figure 6 As shown, the notch 310 of the main pawl 300 of this disclosure has a first sidewall close to the latch member 200 and a second sidewall away from the latch member 200. The stop surface is formed on the first sidewall, thereby the auxiliary pawl 500 of this disclosure applies a pushing force to the main pawl 300, that is, it can restrict the main pawl 300 to a first position.

[0062] Furthermore, the fourth axis of this disclosure is also located away from the latch member 200. Specifically, the first sidewall of the latch member 200 of this disclosure is located between the latch member 200 and the fourth axis.

[0063] like Figure 8 As shown, the auxiliary pawl 500 of this disclosure includes a drive arm 510, the end face of which can engage with the stop surface of the main pawl 300 so that the drive arm 510 can apply a thrust to the main pawl 300.

[0064] like Figure 4 In the indicated state, the drive arm 510 can apply a pushing force to the main pawl 300, and correspondingly, the main pawl 300 can apply a reaction force to the drive arm 510. The drive arm 510 is configured such that the reaction force can drive the drive arm 510 to have a tendency to rotate along a first direction, which can be... Figure 4 The direction is counterclockwise. At this position, the drive arm 510 (i.e., the auxiliary pawl 500) can be restricted in position by the secondary pawl 400, and the locking system will not be unlocked accordingly.

[0065] In other words, when the lock system is unlocked, the secondary pawl 400 can directly or indirectly drive the auxiliary pawl 500 to rotate in a second direction, which is opposite to the first direction; that is, the second direction can be... Figure 4 In a clockwise direction, the drive arm 510 will move into the notch of the main pawl 300, so that the main pawl 300 is released.

[0066] In this disclosure, when the auxiliary pawl 500 is driven and rotated by the auxiliary pawl 400, the auxiliary pawl 500 can drive the main pawl 300 to rotate. In other words, the auxiliary pawl 500 of this disclosure can not only restrict the position of the main pawl 300, but also serve as a power element to drive the main pawl 300 to move. Thus, in the lock system of this disclosure, the number of parts is reduced and the stability of the lock system is improved through optimized structural design.

[0067] To be specific, such as Figure 5 As shown, the side surface of the drive arm 510 of this disclosure can engage with the recess 310 of the main pawl 300, thereby driving the main pawl 300 to move from a first position to a second position. In other words, when the drive arm 510 moves into the recess 310, it can apply a pushing force to the second sidewall of the recess 310 (i.e., the sidewall away from the latch member 200), thereby causing the main pawl 300 to move along... Figure 5 The main pawl 300 is rotated counterclockwise as shown, so that it moves from the first position to the second position.

[0068] Furthermore, when the main pawl 300 is in the second position, at least a portion of the end of the drive arm 510 is located within the recess 310 of the main pawl 300. That is, the recess 310 of the drive arm 510 of this disclosure also forms a clearance space for the movement of the drive arm 510, thereby enabling the auxiliary pawl 500 to be driven and rotated.

[0069] like Figure 7 and Figure 8 As shown, the locking system of this disclosure also includes an intermediate transmission member 600, through which the secondary pawl 400 drives the auxiliary pawl 500 to rotate. In other words, the secondary pawl 400 of this disclosure can be indirectly connected to and indirectly drive the auxiliary pawl 500. Thus, the locking system of this disclosure solves the problem of driving force transmission between the secondary pawl 400 and the main pawl 300 at different levels.

[0070] Specifically, along the axial direction of the first axis (or other axis), the secondary pawl 400 and the intermediate transmission member 600 are at the same height, and the main pawl 300 and the auxiliary pawl 500 are at the same height. At this time, the intermediate transmission member 600 and the auxiliary pawl 500 have the same axis of rotation and are connected to each other by force transmission. Thus, the intermediate transmission member 600 and the auxiliary pawl 500 of this disclosure can rotate synchronously.

[0071] The lock system disclosed herein also includes a pawl signal drive rod 700, which is configured to rotate about a fifth axis. An intermediate transmission member 600 is used to drive the pawl signal drive rod 700 to rotate so that the pawl signal drive rod 700 can trigger or release the pawl signal switch 800.

[0072] Specifically, with Figure 7 As shown, when the secondary pawl 400 rotates counterclockwise, it drives the intermediate transmission component 600 to rotate clockwise. When the intermediate transmission component 600 rotates clockwise, it releases the position restriction on the pawl signal drive rod 700. At this time, the pawl signal drive rod 700 can rotate counterclockwise under the reset force provided by the return spring, triggering the pawl signal switch 800. Therefore, when the pawl signal switch 800 is triggered, the locking system is not in the locked state, that is, it can be in a half-locked state or an unlocked state.

[0073] When the locking tongue component 200 is in the fully locked position and the main pawl 300 is in the second position, the main pawl 300 can move from the second position to the first position under the action of the reset force provided by the reset spring. At this time, the auxiliary pawl 500 and the intermediate transmission component 600 can rotate counterclockwise under the action of the reset force provided by the reset spring.

[0074] The counterclockwise rotation of the auxiliary pawl 500 will drive the pawl signal drive rod 700 to rotate clockwise. At this time, the pawl signal drive rod 700 will release the pawl signal switch 800. Thus, the state of the pawl signal switch 800 can indicate that the locking system is in the locked state (i.e., locked state).

[0075] See again Figure 8 The pawl signal drive lever 700 disclosed herein includes a force-receiving arm 710, and the intermediate transmission member 600 includes a cylindrical portion 610, which can apply a thrust to the force-receiving arm 710, thereby driving the pawl signal drive lever 700 to rotate.

[0076] In addition, the lock system disclosed herein can also detect the position of the bolt component 200 through the bolt signal switch 900. The setting position and working principle of the bolt signal switch 900 can be implemented using existing technologies, and will not be described in detail here.

[0077] According to another aspect of this disclosure, a motor vehicle is provided that includes the aforementioned locking system.
