[0075] 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.

[0076] 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.

[0077] 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.

[0078] The use of crosshairs and / or shading in the accompanying drawings is generally used to clarify the boundaries between adjacent components. Thus, unless otherwise stated, the presence or absence of crosshairs or shading does not convey or indicate any preference or requirement for the specific material, material properties, dimensions, proportions, commonalities between the illustrated components, or any other characteristics, properties, etc., of the components. Furthermore, in the accompanying drawings, the dimensions and relative dimensions of components may be exaggerated for clarity and / or descriptive purposes. When exemplary embodiments can be implemented differently, a specific process sequence may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in the reverse order of their description. Furthermore, the same reference numerals denote the same components.

[0079] When a component is referred to as being "on" or "above" another component, "connected to," or "joined to" another component, the component may be directly on, directly connected to, or directly joined to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to," or "directly joined to" another component, there are no intermediate components. Therefore, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have intermediate components.

[0080] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” another component or feature would subsequently be positioned “above” said other component or feature. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0081] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, parts, components, and / or groups thereof. It should also be noted that, as used herein, the terms “substantially,” “about,” and other similar terms are used as approximate terms rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values ​​that would be recognized by one of ordinary skill in the art.

Figure 5 This is a partial structural schematic diagram of a locking system according to one embodiment of the present disclosure. Figure 6 This is a structural schematic diagram of a portion of the lock system according to one embodiment of the present disclosure from another angle. Figure 7 This is a schematic diagram of the structure of the unlocking cam of a lock system according to one embodiment of the present disclosure. Figure 8 This is a schematic diagram of the structure of a latch component 200 according to one embodiment of the present disclosure.

[0083] like Figures 1 to 8 As shown, the locking system disclosed herein can lock the tailgate of a motor vehicle (vehicle) to or unlock it from the vehicle body during use. This tailgate can also be referred to as a trunk door. In other words, the locking system disclosed herein can also be referred to as a tailgate lock.

[0084] The lock system disclosed herein may include components such as a lock housing 100, a bolt assembly 200, a pawl assembly 300, and a drive mechanism 400. The lock housing 100 can be fixed to the vehicle body or the tailgate, thereby securing the lock system. In this case, the latch will be fixed to the tailgate or the vehicle body, and the tailgate can be locked and unlocked by locking and releasing the latch through the lock system.

[0085] In this disclosure, the latch component 200 is rotatably disposed on the lock housing 100 and has a first axis of rotation. The latch component 200 of this disclosure includes at least an unlocked position and a locked position. In a preferred embodiment, the locked position may include a fully locked position and a partially locked position. In this case, the rotation direction of the latch component 200 can be divided into a locking direction and an unlocking direction. Figure 3 The directions shown indicate that the locking direction is clockwise and the unlocking direction is counterclockwise.

[0086] When the latch component 200 rotates in the locking direction, it can move sequentially from the unlocked position to the half-locked position and then to the fully locked position. Conversely, when the latch component 200 rotates in the unlocking direction, it can move sequentially from the fully locked position to the half-locked position and then to the unlocked position.

[0087] The ratchet component 300 of this disclosure is rotatably disposed on the lock housing 100, and the ratchet component 300 has a second axis of rotation, the first axis of rotation and the second axis of rotation being parallel to each other. The ratchet component 300 is used to restrict the latch component 200 to the locked position.

[0088] Specifically, the pawl component 300 has a first pawl position and a second pawl position. When the pawl component 300 is in the first pawl position, it can cooperate with the locking tongue component 200 and restrict the locking tongue component 200 to a fully locked or half-locked position. When the pawl component 300 is in the second pawl position, it can move away from the locking tongue component 200, at which time the locking tongue component 200 can rotate freely. For example, the locking tongue component 200 can rotate in the unlocking direction under the action of the reset force provided by the reset spring 470.

[0089] The drive device 400 is used to drive the pawl component 300 to rotate so that the lock system can be unlocked; specifically, the drive device 400 of this disclosure can drive the lever component 500 to rotate, and the rotation of the lever component 500 causes the pawl component 300 to rotate.

[0090] In this disclosure, the actuating lever component 500 is rotatably disposed in the lock housing 100 and has a fourth rotation axis, which may be parallel or substantially parallel to the first rotation axis. Figure 6 As shown in the direction, when the lock system of this disclosure is unlocked, the toggle lever component 500 will be driven and rotated counterclockwise. At this time, the toggle lever component 500 will drive the pawl component 300 to rotate clockwise, and correspondingly, the pawl component 300 will move from the first pawl position to the second pawl position.

[0091] In a preferred embodiment, one end of the toggle lever component 500 (e.g.) Figure 6 The lower end of the lever component 500 (in the direction shown) is formed as an outwardly convex curved surface, and one end of the lever component 500 is slidably disposed in the groove of the pawl component 300, so that the lever component 500 of the present disclosure will not disengage from the pawl component 300.

[0092] The structure of the drive device of this disclosure will be described below with reference to the accompanying drawings.

[0093] like Figure 6 As shown, the drive device disclosed herein may include structures such as a drive motor 410, a drive worm 420, a drive worm wheel 430, a transmission gear 440, and a drive cam 450.

[0094] Specifically, the drive motor 410 disclosed herein can be a DC motor. A drive worm 420 is provided on the output shaft of the drive motor 410, and the drive worm 420 cooperates with the drive worm wheel 430. At this time, the rotation axis of the drive motor 410 is perpendicular or approximately perpendicular to the rotation axis (third rotation axis) of the drive worm wheel 430.

[0095] The transmission gear 440 disclosed herein is rotatably disposed on the lock housing 100, and the transmission gear 440 has a fifth axis of rotation. In a specific embodiment, the transmission gear 440 has a driving gear and a driven gear, a driving worm gear 430 for driving the driving gear to rotate, and the driven gear for driving 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.

[0096] Specifically, the drive device disclosed herein also includes a pinion coaxially arranged with the drive worm gear 430, wherein the pinion rotates synchronously with the drive worm gear 430, and at this time, the pinion can mesh with the drive gear; moreover, the driven gear meshes with the drive cam 450, so that the driven gear can drive the drive cam 450 to rotate.

[0097] The drive device 400 of this disclosure further includes a shaft component 460, the central axis of which is the third rotation axis. Correspondingly, the drive worm gear 430 and the drive cam 450 can be coaxially arranged. That is, the drive cam 450 is rotatably and slidably arranged on the shaft component 460; the drive worm gear 430 is rotatably and slidably arranged on the shaft component 460; and a spring 470 is arranged between the drive worm gear 430 and the drive cam 450, the spring 470 being in a pre-compressed state. In other words, the spring 470 of this disclosure can always apply a thrust to the drive worm gear 430 and the drive cam 450, thereby causing the drive worm gear 430 and the drive cam 450 to have a tendency to move away from each other.

[0098] See again Figure 6 The drive device 400 of this disclosure is also used to drive the bolt member 200 to rotate so that the lock system is locked; that is, the lock system of this disclosure can realize electric locking and electric unlocking. Of course, the lock system of this disclosure can also be manually locked. In this case, by applying a driving force to the back door, the latch will drive the bolt member 200 to rotate in the locking direction and realize the locking of the lock system.

[0099] Specifically, with Figure 6 As shown, when the drive cam 450 rotates clockwise, it pushes the latch component 200 to rotate counterclockwise, thus achieving electric locking of the lock system. Conversely, when the drive cam 450 rotates counterclockwise, it pushes the actuating lever component 500 to rotate counterclockwise, and the counterclockwise rotation of the actuating lever component 500 drives the pawl component 300 to rotate clockwise, thereby unlocking the lock system.

[0100] In this disclosure, such as Figure 7 and Figure 8 As shown, the drive cam 450 includes a first drive surface 451 and a second drive surface 452. Under normal operating conditions, the first drive surface 451 can contact the actuating lever component 500 and apply a thrust to the actuating lever component 500 to rotate it. Similarly, the second drive surface 452 can cooperate with the latch force-receiving surface 201 of the latch component 200 to rotate the latch component 200 and lock the lock system.

[0101] In other words, when the lock system is in normal working condition, the driving component of the drive cam 450 (i.e., the first driving surface and the second driving surface) will be between the force-bearing component of the latch component 200 (i.e., the latch force-bearing surface and the latch force-applying surface) and the actuating lever component 500. At this time, the first driving surface 451 and the latch force-applying surface 202 will be opposite to each other. However, when the lock system is in the wrong position, the force-bearing component of the latch component 200 will be located between the driving component of the drive cam 450 and the actuating lever component 500. At this time, the drive cam 450 not only cannot drive the latch component 200 to lock, but it also hinders the latch component 200 from rotating in the locking direction, causing the lock system to fail to lock.

[0102] To address this, the first driving surface 451 of the drive cam 450 of this disclosure includes a first inclined surface. When the latching force-applying surface 202 of the latching tongue member 200 contacts the first driving surface 451, the latching force-applying surface 202 of the latching tongue member 200 can apply a positive pressure to the first inclined surface, causing the drive cam 450 to move along the direction of the third rotation axis. Thus, the latching tongue member 200 of this disclosure can drive the drive cam 450 to a position where the latching tongue member 200 is not in the same plane. At this time, the drive cam 450 will not affect the rotation of the latching tongue member 200 in the locking direction, and correspondingly, the latching tongue member 200 can lock smoothly.

[0103] Specifically, the first inclined surface is configured such that when the latch member 200 rotates in the locking direction, the latch member 200 drives the drive cam 450 to move in a direction close to the drive worm gear 430. That is to say, the first inclined surface of the drive cam 450 of this 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.

[0104] The drive cam 450 disclosed herein may have a toothed structure formed on its outer peripheral surface, which can mesh with a driven gear, thereby driving the drive cam 450 to rotate. Alternatively, the drive cam 450 may be separately disposed from the gear component with the toothed structure, and the gear component may drive the drive cam 450 to rotate.

[0105] 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 arrangement of the transmission gears of this disclosure, the rotational speed of the driving worm gear 430 is greater than the rotational speed of the driving cam 450, thus realizing the speed reduction transmission from the driving worm gear 430 to the driving cam 450.

[0106] In this disclosure, the locking tongue force-applying surface 202 includes a second inclined surface, which cooperates with the first inclined surface. In other words, the second inclined surface of this disclosure may have approximately the same inclined direction and inclined angle as the first inclined surface.

[0107] In this disclosure, when the drive worm wheel 430 moves along the third rotation axis, the drive worm wheel 430 can disengage from the drive worm 420. Specifically, when the drive worm wheel 430 moves along the third motion axis in a direction close to the drive cam 450, the drive worm wheel 430 can disengage from the drive worm 420.

[0108] In one embodiment, the locking system further includes an emergency unlocking knob 600, which drives the drive worm gear 430 to move along a third rotation axis, thereby disengaging the drive worm gear 430 from the drive worm 420. That is, in an emergency, such as when the locking system is locked and power is cut off, the emergency unlocking knob 600 can be rotated to disengage the drive worm gear 430 from the drive worm 420. At this time, the transmission system will not self-lock. Then, the pawl component 300 (or the unlocking lever component 350 described below) can be actuated and driven to the second pawl position. At this time, the latch component 200 will rotate and unlock, thus realizing the emergency unlocking function of the locking system.

[0109] Figure 9 This is a structural schematic diagram of an unlocking lever component and a pawl component according to one embodiment of the present disclosure. Figure 10 This is a structural schematic diagram of an unlocking lever component according to one embodiment of the present disclosure. Figure 11 This is a schematic diagram of the structure of a pawl component according to one embodiment of the present disclosure.

[0110] In a preferred embodiment, such as Figures 9 to 11 As shown, the lock system of this 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 axis of rotation. In this case, when the drive 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. Simultaneously, 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, at which point the lock system can be unlocked.

[0111] Furthermore, 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, in the event of an emergency unlocking, the lock system of this disclosure can directly move the unlocking lever component 350, causing the pawl component 300 to 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, thereby enabling the lock system of this disclosure to be unlocked in an emergency.

[0112] 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. The unlocking lever protrusion 351 can slide within the pawl groove 310 and can be positioned by a side wall of the pawl groove 310, thereby enabling the unlocking lever component 350 to drive the pawl component 300 to rotate. Conversely, as 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 towards a position close to the latch component 200.

[0113] In one embodiment, the lock system further includes a bolt position detection switch 700, which is triggered when the bolt component 200 is in the unlocked position, so that the bolt can be detected as being in the unlocked state.

[0114] The lock system disclosed herein also includes a pawl position detection switch 800, which is not triggered when the lock system is in a fully locked state; and is triggered when the lock system is in a partially locked state or an unlocked state.

[0115] Furthermore, the locking system disclosed herein may also include: a first cam position detection switch 900 and a second cam position detection switch 910; wherein, when the drive cam 450 is in the position where the drive pawl component 300 is in the position where the release bolt component 200 is located, the first cam position detection switch 900 is triggered; when the drive cam 450 is in the position where the drive bolt component 200 is in the locked position, the first cam position detection switch 900 is triggered. That is to say, the first cam position detection switch 900 can be considered as a neutral position switch, that is, when the drive cam 450 is in the neutral position, the first cam position detection switch 900 will not be triggered.

[0116] In other words, the outer peripheral surface of the drive cam 450 disclosed herein is provided with a drive feature, which is formed as a protrusion or groove on the outer peripheral surface of the drive cam 450. The first cam position detection switch 900 and the second cam position detection switch 910 will cooperate with the drive feature of the drive cam 450 so that the first cam position detection switch 900 or the second cam position detection switch 910 can be triggered when the drive cam 450 rotates.

[0117] Furthermore, when the drive cam 450 is in a position close to the toggle lever component 500, the second cam position detection switch 910 is not triggered. That is, the second cam position detection switch 910 can be used to determine whether the drive cam 450 is near the toggle lever component 500.

[0118] In one embodiment, the lock housing 100 of this disclosure may include an actuator housing and a lock body housing, wherein the actuator housing may be integrally formed with the lock body housing.

[0119] In a preferred embodiment, the latch component 200 includes a first latch feature 203 and a second latch feature 204. When the pawl component 300 engages with the first latch feature 203, it restricts the latch component 200 to a fully locked position. When the pawl component 300 engages with the second latch feature 204, it restricts the latch component 200 to a partially locked position. The engagement amount between the pawl component 300 and the first latch feature 203 is greater than the engagement amount between the pawl component 300 and the second latch feature 204. In other words, when the lock system is in the fully locked position, the pawl component 300 is closer to the latch component 200 than in the partially locked position.

[0120] 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 the position, the pawl position detection switch 800 will be triggered. Thus, by the signal change of the pawl position detection switch 800, it is possible to determine whether the lock system is in the fully locked state.

[0121] According to another aspect of this disclosure, a motor vehicle is provided that includes the aforementioned locking system.
