Figure 7 is a schematic structural diagram of an unlocking cam of a lock system according to an embodiment of the present disclosure. Figure 8 is a schematic structural diagram of a locking tongue component 200 according to an embodiment of the present disclosure.

[0044] like Figures 1 to 8 As shown, the lock system of the present invention can lock the back door of a motor vehicle (vehicle) to the vehicle body or unlock it from the vehicle body when in use, wherein the back door can also be called a luggage compartment door. In other words, the lock system of the present invention can also be called a back door lock.

[0045] The lock system of the present disclosure may include a lock housing 100, a lock tongue component 200, a pawl component 300, and a driving device 400. The lock housing 100 can be fixed to a vehicle body or a back door, so that the lock system of the present disclosure can be fixed. At this time, the lock buckle will be fixed to the back door or the vehicle body, so that the back door can be locked and unlocked by locking and releasing the lock buckle by the lock system.

[0046] In the present disclosure, the bolt component 200 is rotatably disposed on the lock housing 100 and has a first rotation axis. The bolt component 200 of the present disclosure includes at least an unlocking position and a locking position. In a preferred embodiment, the locking position may include a full locking position and a half locking position. At this time, the rotation direction of the bolt component 200 can be divided into a locking direction and an unlocking direction. Figure 3 In the direction shown, the locking direction is clockwise and the unlocking direction is counterclockwise.

[0047] When the bolt component 200 rotates along the locking direction, it can move to the half-lock position and the fully locked position from the unlocking position in sequence. On the contrary, when the bolt component 200 rotates along the unlocking direction, it can move to the half-lock position and the unlocking position in sequence from the fully locked position.

[0048] The pawl component 300 of the present disclosure is rotatably disposed on the lock housing 100, and the pawl component 300 has a second rotation axis, and the first rotation axis and the second rotation axis can be parallel to each other. The pawl component 300 is used to limit the bolt component 200 to a locked position.

[0049] Specifically, the pawl component 300 has a first pawl position and a second pawl position, wherein when the pawl component 300 is in the first pawl position, the pawl component 300 can cooperate with the lock tongue component 200 and limit the lock tongue component 200 to a fully locked position or a half-locked position, and when the pawl component 300 is in the second pawl position, the pawl component 300 can be away from the lock tongue component 200, at which time the lock tongue component 200 will be able to rotate freely, for example, the lock tongue component 200 can rotate in the unlocking direction under the action of the reset force provided by the reset spring 470.

[0050] The driving device 400 is used to drive the pawl component 300 to rotate so that the lock system is unlocked; specifically, the driving device 400 of the present disclosure can drive the toggle rod component 500 to rotate, and the pawl component 300 is rotated by the rotation of the toggle rod component 500.

[0051] In the present disclosure, the toggle lever component 500 is rotatably disposed on the lock housing 100 and has a fourth rotation axis, which may be parallel or substantially parallel to the first rotation axis. Figure 6 In the direction shown, when the lock system of the present invention is unlocked, the toggle lever component 500 will be driven and rotated counterclockwise, and the toggle lever component 500 will drive the pawl component 300 to rotate clockwise, and accordingly, the pawl component 300 will move from the first pawl position to the second pawl position.

[0052] In a preferred embodiment, one end of the toggle lever component 500 (eg Figure 6The lower end in the direction shown in the figure is formed as a curved surface convex outward, and one end of the toggle rod component 500 is slidably disposed in the groove of the pawl component 300, thereby, the toggle rod component 500 of the present disclosure will not fall out of the pawl component 300.

[0053] The structure of the driving device disclosed in the present invention will be described below with reference to the accompanying drawings.

[0054] like Figure 6 As shown, the driving device of the present disclosure may include: a driving motor 410 , a driving worm 420 , a driving worm wheel 430 , a transmission gear 440 , a driving cam 450 and other structures.

[0055] Specifically, the drive motor 410 of the present disclosure may be a DC motor. A drive worm 420 is disposed on the output shaft of the drive motor 410, and the drive worm 420 cooperates with the drive worm wheel 430, and at this time, the rotation axis of the drive motor 410 is perpendicular or substantially perpendicular to the rotation axis (third rotation axis) of the drive worm wheel 430.

[0056] The transmission gear 440 of the present disclosure is rotatably disposed on the lock housing 100, and the transmission gear 440 has a fifth rotation axis. In a specific embodiment, the transmission gear 440 has a driving gear and a driven gear, the driving worm gear 430 is used to drive the driving gear to rotate, and the driven gear is used to drive the driving cam 450 to rotate; wherein the driving gear and the driven gear rotate synchronously. For example, the driving gear and the driven gear can be integrally formed.

[0057] Specifically, the driving device of the present invention also includes a pinion gear coaxially arranged with the driving worm gear 430, wherein the pinion gear rotates synchronously with the driving worm gear 430, and at this time, the pinion gear can engage with the driving gear; and the driven gear engages with the driving cam 450, so that the driven gear can drive the driving cam 450 to rotate.

[0058] The driving device 400 of the present disclosure further includes a shaft component 460, the central axis of which is the third rotation axis, and accordingly, the driving worm wheel 430 and the driving cam 450 can be coaxially arranged. That is, the driving cam 450 is rotatably and slidably arranged on the shaft component 460; the driving worm wheel 430 is rotatably and slidably arranged on the shaft component 460, and a spring 470 is arranged between the driving worm wheel 430 and the driving cam 450, and the spring 470 is in a pre-compressed state. That is, the spring 470 of the present disclosure can always apply thrust to the driving worm wheel 430 and the driving cam 450, so that the driving worm wheel 430 and the driving cam 450 have a tendency to move away from each other.

[0059] Refer to Figure 6The driving device 400 of the present invention is also used to drive the lock tongue component 200 to rotate so that the lock system is locked; that is, the lock system of the present invention can realize electric locking and electric unlocking. Of course, the lock system of the present invention can also be locked manually. In this case, by applying a driving force to the back door, the lock buckle will drive the lock tongue component 200 to rotate in the locking direction and realize the locking of the lock system.

[0060] Specifically, Figure 6 In the direction shown, when the driving cam 450 rotates clockwise, it can push the bolt component 200 to rotate counterclockwise, and the electric locking of the lock system can be achieved. In the opposite direction of movement, when the driving cam 450 rotates counterclockwise, it can push the toggle lever component 500 to rotate counterclockwise, and the counterclockwise rotation of the toggle lever component 500 drives the pawl component 300 to rotate clockwise, thereby unlocking the lock system.

[0061] In this disclosure, Figure 7 and Figure 8 As shown, the driving cam 450 includes a first driving surface 451 and a second driving surface 452. Under normal working conditions, the first driving surface 451 will be able to contact the toggle lever component 500 and apply a thrust to the toggle lever component 500 to push the toggle lever component 500 to rotate. Similarly, the second driving surface 452 will be able to cooperate with the bolt force-bearing surface 201 of the bolt component 200 to push the bolt component 200 to rotate and lock the lock system.

[0062] That is to say, when the lock system is in a normal working state, the driving part (i.e., the first driving surface and the second driving surface) of the driving cam 450 will be between the force-bearing part (i.e., the force-bearing surface and the force-applying surface) of the lock tongue part 200 and the toggle rod part 500, and at this time, the first driving surface 451 and the force-applying surface 202 of the lock tongue part will be separated. However, when the lock system is in a wrong position, the force-bearing part of the lock tongue part 200 will be located between the driving part of the driving cam 450 and the toggle rod part 500, and at this time, the driving cam 450 not only cannot drive the lock tongue part 200 to lock, but also hinders the lock tongue part 200 from rotating in the locking direction, resulting in the lock system being unable to lock.

[0063] In view of this, the first driving surface 451 of the driving cam 450 of the present disclosure includes a first inclined surface. When the locking tongue force-applying surface 202 of the locking tongue component 200 contacts the first driving surface 451, the locking tongue force-applying surface 202 of the locking tongue component 200 can apply positive pressure to the first inclined surface and make the driving cam 450 move along the direction of the third rotation axis. Thus, the locking tongue component 200 of the present disclosure can drive the driving cam 450 to a position where the locking tongue component 200 is not in the same plane. At this time, the driving cam 450 will not affect the rotation of the locking tongue component 200 in the locking direction. Accordingly, the locking tongue component 200 can be locked smoothly.

[0064] Specifically, the first inclined surface is configured such that when the locking tongue component 200 rotates in the locking direction, the locking tongue component 200 drives the driving cam 450 to move in a direction close to the driving worm gear 430. In other words, the first inclined surface of the driving cam 450 of the present disclosure is no longer parallel to the third rotation axis, but has a preset angle with the third rotation axis, and the first inclined surface cannot be perpendicular to the third rotation axis.

[0065] The driving cam 450 of the present disclosure may be formed with a tooth structure on its outer circumference, and the tooth structure may mesh with a driven gear, so that the driving cam 450 may be driven to rotate by the driven gear. In addition, the driving cam 450 may also be provided separately from a gear component having a tooth structure, and the gear component may drive the driving cam 450 to rotate.

[0066] In a preferred embodiment, the number of teeth of the driving gear is greater than the number of teeth of the driven gear. Accordingly, through the setting of the transmission gear disclosed in the present invention, the rotation speed of the driving worm gear 430 will be greater than the rotation of the driving cam 450, thereby realizing the speed reduction transmission from the driving worm gear 430 to the driving cam 450.

[0067] In the present disclosure, the bolt force-applying surface 202 includes a second inclined surface, and the second inclined surface cooperates with the first inclined surface. In other words, the second inclined surface of the present disclosure can have substantially the same inclined direction and inclined angle as the first inclined surface.

[0068] In the present disclosure, when the driving worm wheel 430 moves along the third rotation axis, the driving worm wheel 430 can be separated from the driving worm 420. Specifically, when the driving worm wheel 430 moves along the third movement axis in a direction close to the driving cam 450, the driving worm wheel 430 can be separated from the driving worm 420.

[0069] In one embodiment, the lock system further includes: an emergency unlocking knob 600, which is used to drive the driving worm wheel 430 to move along the third rotation axis so that the driving worm wheel 430 is disengaged from the driving worm 420. That is to say, in an emergency state, for example, when the lock system is locked and the power is cut off, the emergency unlocking knob 600 can be turned to disengage the driving worm wheel 430 from the driving worm 420, and the transmission system will not be self-locking at this time, and then the pawl component 300 (or the unlocking rod component 350 described below) is moved, and the pawl component 300 is driven to the second pawl position, and the lock tongue component 200 will rotate and unlock, thereby realizing the emergency unlocking function of the lock system.

[0070] Fig. 9 It is a schematic structural diagram of an unlocking lever component and a pawl component according to an embodiment of the present disclosure. Fig.10 It is a schematic structural diagram of an unlocking lever component according to an embodiment of the present disclosure. Fig.11 It is a schematic structural diagram of a pawl component according to an embodiment of the present disclosure.

[0071] In a preferred embodiment, Figures 9 to 11 As shown, the lock system of the present disclosure may further include an unlocking lever component 350, which is rotatably disposed on the lock housing 100, and the unlocking lever component 350 and the pawl component 300 have the same rotation axis. At this time, when the driving cam 450 drives the pawl component 300 to move from the first pawl position to the second pawl position, the pawl component 300 will not drive the unlocking lever component 350 to rotate. At the same time, when the unlocking lever component 350 is driven and rotates in a direction away from the bolt component 200, the unlocking lever component 350 will drive the pawl component 300 to move from the first pawl position to the second pawl position, and the lock system can be unlocked at this time.

[0072] Moreover, when the unlocking lever component 350 rotates, it can cooperate with the emergency unlocking knob 600 to drive the emergency unlocking knob 600 to rotate. Specifically, when the lock system of the present disclosure is emergency unlocked, the unlocking lever component 350 can be directly moved to make the pawl component 300 move from the first pawl position to the second pawl position. At the same time, the unlocking lever component 350 will drive the emergency unlocking knob 600 to rotate, so that the lock system of the present disclosure is emergency unlocked.

[0073] In a preferred embodiment, the unlocking lever component 350 has an unlocking lever protrusion 351, and correspondingly, the pawl component 300 has a pawl groove 310, and the unlocking lever protrusion 351 can slide in the pawl groove 310 and can be limited by a side wall of the pawl groove 310, thereby, the unlocking lever component 350 can drive the pawl component 300 to rotate. In the opposite direction, when the pawl component 300 moves from the second pawl position to the first pawl position, it can drive the unlocking lever component 350 to move to a position close to the lock tongue component 200.

[0074] In one embodiment, the lock system further includes: a lock tongue position detection switch 700. When the lock tongue component 200 is in the unlocked position, the lock tongue position detection switch 700 is triggered. At this time, the lock tongue can be detected to be in the unlocked state through the lock tongue position detection switch 700.

[0075] The lock system of the present disclosure further includes a pawl position detection switch 800. When the lock system is in a fully locked state, the pawl position detection switch 800 is not triggered; when the lock system is in a half-locked state or an unlocked state, the pawl position detection switch 800 is triggered.

[0076] In addition, the lock system of the present disclosure may further include: a first cam position detection switch 900 and a second cam position detection switch 910; wherein, when the driving cam 450 is in the position of driving the pawl component 300 to release the lock tongue component 200, the first cam position detection switch 900 is triggered; when the driving cam 450 is in the position of driving the lock tongue component 200 to lock, the first cam position detection switch 900 is triggered. In other words, the first cam position detection switch 900 can be considered as a neutral switch, that is, when the driving cam 450 is in the neutral position, the first cam position detection switch 900 will not be triggered.

[0077] That is to say, the outer peripheral surface of the driving cam 450 of the present disclosure is provided with a driving feature, which is formed as a protrusion or a groove on the outer peripheral surface of the driving cam 450. The first cam position detection switch 900 and the second cam position detection switch 910 will cooperate with the driving feature of the driving cam 450 so that when the driving cam 450 rotates, the first cam position detection switch 900 or the second cam position detection switch 910 can be triggered.

[0078] In addition, when the driving cam 450 is located near the toggle lever member 500 , the second cam position detection switch 910 is not triggered. In other words, whether the driving cam 450 is located near the toggle lever member 500 can be obtained through the second cam position detection switch 910 .

[0079] In one embodiment, the lock housing 100 of the present disclosure may include an actuator housing and a lock body housing, wherein the actuator housing may be integrally formed with the lock body housing.

[0080] In a preferred embodiment, the lock tongue component 200 includes a first lock tongue feature 203 and a second lock tongue feature 204, wherein when the pawl component 300 cooperates with the first lock tongue feature 203, the pawl component 300 is used to limit the lock tongue component 200 to the fully locked position, and when the pawl component 300 cooperates with the second lock tongue feature 204, the pawl component 300 is used to limit the lock tongue component 200 to the semi-locked position, wherein the engagement amount of the pawl component 300 with the first lock tongue feature 203 is greater than the engagement amount of the pawl component 300 with the second lock tongue feature 204. In other words, compared with the semi-locked position, when the lock system is in the fully locked position, the pawl component 300 is closer to the lock tongue component 200.

[0081] Therefore, when the lock system is in the fully locked state, the pawl position detection switch 800 will not be triggered. When the pawl component 300 leaves this position, the pawl position detection switch 800 will be triggered. Therefore, through the signal change of the pawl position detection switch 800, it can be obtained whether the lock system is in the fully locked state.

[0082] According to another aspect of the present disclosure, a motor vehicle is provided, comprising the above locking system.
