Description

Technical Field

[0001] This invention relates to the field of vehicles, and more specifically to a vehicle lock assembly. Background Technology

[0002] Generally, car door locks have a central locking function for locking and unlocking. For example, when the lock is locked, the door cannot be opened by pulling a specific handle (e.g., the inside or outside handle), while when the lock is unlocked, the door can be opened by pulling the same handle. The lock contains a power source, such as a motor, to perform the central locking function.

[0003] Some car locks, in addition to central locking, also have an electric closing function, meaning the lock can move the door from a loose position to a closed position. Car locks with both central locking and electric closing functions usually have at least two power sources, such as two motors, to perform these two functions separately, resulting in higher cost, size, and weight.

[0004] Therefore, it is hoped that a solution can be proposed that can solve the above problems. Summary of the Invention

[0005] To address the above problems, according to a first aspect of the present invention, a vehicle lock assembly is provided, comprising: a first mechanism coupled to a power source, wherein the first mechanism is driveable by the power source to cause the vehicle lock assembly to perform electrical engagement, wherein the first mechanism includes a first portion driven by the power source; and a second mechanism including a second portion, wherein the second portion is configured to move between an unlocked position and a locked position, wherein in the unlocked position the second portion unlocks the vehicle lock assembly, and in the locked position the second portion locks the vehicle lock assembly, wherein the vehicle lock assembly includes a coupling mechanism, wherein the first portion and the second portion are coupled to each other via the coupling mechanism, such that the first portion can drive the second portion to move between the unlocked position and the locked position, wherein the second portion can also be driven independently of the first portion to decouple the first portion and the second portion, and the second portion can move independently of the first portion to a new relative position and remain in that new relative position.

[0006] The vehicle lock assembly according to the present invention can be controlled by a single power source (e.g., a motor) for locking, unlocking, and electric engagement, resulting in lower cost, smaller size, and lighter weight. Due to the aforementioned configuration of the vehicle lock assembly, no external power supply is required, thus reducing the number of wiring harness connectors and also reducing the space occupied inside the vehicle door.

[0007] Meanwhile, in the vehicle lock assembly according to the invention, the second part is configured to enable both unlocking and locking of the vehicle lock assembly. Therefore, the second part can be configured to be manually driven (e.g., driven via other components of the second mechanism). Thus, the vehicle lock assembly according to the invention at least allows the first and second parts to be decoupled from each other by manual operation, thereby enabling the second part to be driven independently to unlock or lock the vehicle lock assembly, and the driving of the second part is not transmitted back to the power source. Therefore, the obstruction to manual unlocking or locking operations caused by the difficulty of passively driving the power source (e.g., the difficulty of passively rotating the motor's output shaft) is avoided. Thus, the vehicle lock assembly according to the invention ensures that manual operation can unlock the vehicle lock assembly to allow the door to be opened, effectively improving vehicle security.

[0008] The vehicle lock assembly according to the invention may have one or more of the following features, individually or in combination.

[0009] According to one embodiment, preferably, after the second part is in the new relative position, the first part can be driven independently of the second part to restore the coupling between the first and second parts. The vehicle lock assembly according to this embodiment can, after the first and second parts are decoupled, restore the coupling between them by driving the first part, thereby returning the vehicle lock assembly to a state where the unlocking and locking of the vehicle lock are controlled by a power source.

[0010] According to one embodiment, preferably, the first mechanism includes a drive member driven by a power source, and the first portion is separate from and configured to be driven by the drive member to move the second portion between an unlocked position and a locked position. For the vehicle lock assembly according to this embodiment, the structure and materials of the drive member and the first portion can be configured more flexibly.

[0011] According to one embodiment, preferably, the first mechanism includes a drive member driven by a power source, and the first portion is the drive member or is formed as part of the drive member. The vehicle lock assembly according to this embodiment can have fewer parts, a more compact size, and a simpler assembly process.

[0012] According to one embodiment, preferably, the drive member is configured to move within a drive member travel, the drive member travel including a locking point, an unlocking point, and a magnetic engagement section, wherein the movement of the drive member in the magnetic engagement section enables the vehicle lock assembly to perform electrical engagement. In the vehicle lock assembly according to this embodiment, locking, unlocking, and electrical engagement of the vehicle lock assembly can be controlled by controlling the position state of the drive member, improving the stability of the vehicle lock assembly's operation.

[0013] According to one embodiment, preferably, a locking point, an unlocking point, and a closing section are sequentially arranged along a first stroke direction during the drive member's stroke. When the first and second parts are coupled to each other, as the drive member moves along the first stroke direction in the closing section, the drive member causes the vehicle lock assembly to electrically close, and the second part is in the unlocked position. The vehicle lock assembly according to this embodiment at least facilitates manual opening of the door when the vehicle lock assembly electrically closes, and makes the structure and arrangement of related components in the vehicle lock assembly more rational.

[0014] According to one embodiment, preferably, the vehicle lock assembly includes a latching actuator configured to move the latch in the vehicle lock assembly to a fully closed door position to perform electric latching. The vehicle lock assembly also includes a clutch, wherein, during the electric latching process, when a pull of the door handle is transmitted to the vehicle lock assembly, the clutch drives the latching actuator to disengage from the latch, thereby stopping the electric latching. The vehicle lock assembly according to this embodiment achieves a latching-disengagement function, which at least allows the door to be manually opened while the vehicle lock assembly is performing electric latching, improving vehicle security. It should be noted that, in this disclosure, the term "door handle" refers to either or both of the inner and outer handles of the door.

[0015] According to one embodiment, preferably, the vehicle lock assembly includes a magnetic drive shaft capable of being driven by a drive member to move along a magnetic path. A magnetic actuator is a rotating arm with one end connected to the magnetic drive shaft. During the electric magnetic engagement of the vehicle lock assembly, the magnetic drive shaft drives the magnetic actuator to move along the magnetic path, causing the arm of the magnetic actuator to push the latch bolt. When the door handle is pulled, a clutch member drives the magnetic actuator to rotate relative to the magnetic drive shaft, causing the arm of the magnetic actuator to move away from the latch bolt and disengage from it. The vehicle lock assembly according to this embodiment can at least effectively and stably achieve the magnetic engagement and disengagement function.

[0016] According to one embodiment, preferably, the drive element is a gear, and the engagement drive shaft is fixed to a subsequent gear meshing with the drive element, wherein the transmission ratio between the drive element and the subsequent gear is greater than 3. The vehicle lock assembly according to this embodiment provides at least increased torque for electric engagement.

[0017] According to one embodiment, preferably, during the travel of the drive member, an electric release section, a locking point, an unlocking point, and a latching section are sequentially arranged along a first travel direction. When the first and second parts are coupled to each other, when the drive member moves in the electric release section along a second travel direction opposite to the first travel direction, the drive member causes the vehicle lock assembly to perform an electric release. The vehicle lock assembly according to this embodiment has at least additionally an electric release function driven by the drive member, and the structure and arrangement of the relevant components in the vehicle lock assembly are relatively reasonable.

[0018] According to one embodiment, preferably, when the first part and the second part are coupled to each other, the second part is in the locked position when the drive member moves from the locking point to the electrically released section and moves within the electrically released section along the second stroke direction. In the vehicle lock assembly according to this embodiment, the structure and arrangement of the relevant components can be relatively simple, facilitating the manufacture of the vehicle lock assembly.

[0019] According to one embodiment, preferably, during the travel of the drive member, an ice-breaking section, an electric release section, a locking point, an unlocking point, and a suction section are sequentially arranged along a first travel direction. When the first and second parts are coupled to each other, when the drive member moves in the ice-breaking section along a second travel direction opposite to the first travel direction, the drive member causes the vehicle lock assembly to perform ice-breaking. The vehicle lock assembly according to this embodiment has at least additional ice-breaking functionality driven by the drive member, and the structure and arrangement of the relevant components in the vehicle lock assembly are relatively reasonable.

[0020] According to one embodiment, preferably, when the first part and the second part are coupled to each other, the second part is in the locked position when the drive member moves from the electrically released section to the ice-breaking section and moves within the ice-breaking section along the second stroke direction. In the vehicle lock assembly according to this embodiment, the structure and arrangement of the relevant components can be relatively simple, facilitating the manufacture of the vehicle lock assembly.

[0021] According to one embodiment, preferably, during the movement of the drive member along the second stroke direction in the electrically released section and / or ice-breaking section, if the pull of the inner door handle is transmitted to the door lock assembly, the second part is driven by the inner door handle to move to the unlocked position. According to this embodiment, when the door lock assembly performs electrically released or ice-breaking, the vehicle occupants can still unlock the door via the inner door handle.

[0022] According to one embodiment, preferably, the vehicle lock assembly includes an engaging member and a latch brake, the latch brake being actuated to prevent the latch from stopping. When a second portion moves from the locked position to the unlocked position, the second portion drives the engaging member to move along the engaging direction to engage with the latch brake in the vehicle lock assembly, such that movement of the engaging member in a direction intersecting the engaging direction can actuate the latch brake. Furthermore, when the second portion moves from the unlocked position to the locked position, the second portion drives the engaging member to move against the engaging direction to disengage from the latch brake, such that movement of the engaging member in a direction intersecting the engaging direction cannot actuate the latch brake. The vehicle lock assembly according to this embodiment at least effectively and stably achieves control of the latch brake.

[0023] According to one embodiment, preferably, when the engaging member is engaged with the latch brake, the door handle drives the engaging member to cause the engaging member to drive the latch brake. The vehicle lock assembly according to this embodiment can reliably achieve the function of opening the door via the door handle.

[0024] According to one embodiment, preferably, the second part includes a second part body and a first branch extending from the second part body, and the inner handle of the door drives the second part from a locked position to an unlocked position via the first branch. The door lock assembly according to this embodiment can reliably achieve the function of unlocking via the inner handle.

[0025] According to one embodiment, preferably, the vehicle lock assembly further includes a mechanical lock connector driven by the mechanical lock of the vehicle door. The second part includes a second part body and a second branch extending from the second part body. The mechanical lock connector can act on the second branch to drive the second part from a locked position to an unlocked position or drive the second part from an unlocked position to a locked position. The vehicle lock assembly according to this embodiment can effectively and stably realize the function of locking and unlocking via the mechanical lock, and does not interfere with unlocking via the inner handle.

[0026] According to one embodiment, preferably, the vehicle lock assembly further includes an emergency lock. The second part includes a second part body and a third branch extending from the second part body. The emergency lock can act on the third branch and drive the second part from the unlocked position to the locked position. The vehicle lock assembly according to this embodiment can effectively and stably realize the function of locking via the emergency lock, and does not interfere with locking and unlocking via the mechanical lock.

[0027] According to one embodiment, preferably, the first part and the second part are separate components, but when the first part and the second part are coupled together, they move as a single unit. In the vehicle lock assembly according to this embodiment, the arrangement of the first part and the second part is relatively simple, facilitating the manufacture of the vehicle lock assembly.

[0028] According to one embodiment, preferably, the first part and the second part are coaxially arranged and configured to rotate about a first axis. The vehicle lock assembly according to this embodiment is easy to assemble, and the operation of the first part and the second part is relatively stable.

[0029] According to one embodiment, preferably, the coupling mechanism is a tightly fitted surface area between the first part and the second part, wherein the force that drives the first part independently of the second part and the force that drives the second part independently of the first part are greater than the frictional force that needs to be overcome to generate relative movement between the first and second parts. The vehicle lock assembly according to this embodiment has fewer parts, and the operation of the first and second parts is more stable.

[0030] According to one embodiment, preferably, the coupling mechanism comprises a latching portion provided on a first part and a mating latching portion provided on a second part that latches with the latching portion, wherein the force required to drive the second part independently of the first part is greater than the force required to disengage the latching portion from the mating latching portion, and the force required to drive the first part to re-couple with the second part is greater than the force required to latch the latching portion from the mating latching portion. The vehicle lock assembly according to this embodiment has a smaller number of parts, and the first and second parts are easy to manufacture.

[0031] According to one embodiment, preferably, the first part and the second part are separate components, wherein the first part includes a blocking structure to restrict movement of the second part relative to the first part, so that the first part and the second part are coupled to each other, and wherein, when the second part is driven independently of the first part, the second part moves and / or deforms to pass over the blocking structure to decouple the first part and the second part. In the vehicle lock assembly according to this embodiment, the first part and the second part are easy to manufacture.

[0032] According to one embodiment, preferably, the coupling mechanism is configured such that the second portion is elastically movable and / or deformable relative to the first portion, such that when the second portion is driven independently of the first portion, the second portion slides along the surface of the first portion to pass over the blocking structure.

[0059] The present invention will be described in detail below by way of example embodiments.

[0060] Figure 1A A perspective view of a portion of a vehicle lock assembly 1 according to an embodiment of the present invention is shown. The vehicle lock assembly 1 is configured to be mounted on a vehicle door and is capable of receiving a lock pin mounted at a corresponding position on the vehicle body to close the door. Figure 1A As shown, the vehicle lock assembly 1 includes a latch 51 and a latch brake 52. The latch 51 is configured to rotate about a first axis 81, and the latch 51 is spring-biased to have a certain angle range. Figure 1AThe view shown shows a tendency to rotate counterclockwise. The latch 51 has a latch recess 510 to receive the locking pin (not shown) during door closing, and together with the recess of the locking pin receiver 53, it restricts the locking pin. The latch brake 52 is configured to rotate about a second axis 82, and the latch brake 52 is spring-biased to have a certain angular range... Figure 1A The view shown shows a tendency towards clockwise rotation. It should be noted that, in the preceding and following text, different specific constructions may be used for cases where a particular component is configured to rotate (e.g., restricted rotation) about a corresponding axis, as long as the rotation described in its context can be achieved, and are not limited to the component construction shown in the figures.

[0061] like Figure 1A As shown, the latch 51 has a latch protrusion 511, and the latch brake 52 has a latch stop 521. When the door is closed, the latch stop 521 abuts against the latch protrusion 511 to stop the latch 51 from rotating counterclockwise. When the vehicle lock assembly 1 is in the unlocked state, when the door handle is pulled, the pull of the door handle is transmitted to the vehicle lock assembly 1, causing the latch brake 52 to... Figure 1A In the view shown, rotating counterclockwise, the latch stop 521 no longer stops the latch protrusion 511, allowing the latch 51 to rotate counterclockwise under the spring biasing force. Due to the counterclockwise rotation of the latch 51, the inner wall of the latch recess 510... Figure 1A In the view, the locking cylinder can be pushed to the right and no longer obstructs further movement to the right, thus allowing the locking cylinder to disengage from the vehicle lock assembly 1 and the door to be opened.

[0062] According to an embodiment of the present invention, the locking tongue 51 is a single part. For example... Figure 1A As shown, the latch 51 also has a suction engagement portion 513 and an ice-breaking engagement portion 514. The lock assembly 1 accordingly includes a suction actuator 31 and an ice-breaking actuator 44. The suction actuator 31 is driven by a motor 41 via a gear train, and it engages the latch 51 through the suction engagement portion 513, causing the latch 51 to... Figure 1A Rotating clockwise in the view shown causes the inner wall of the latch recess 510 of the latch 51 to push the locking pin (not shown) already located in the latch recess 510 further to the left. This causes the lock assembly 1 to perform electric engagement. The ice-breaking actuator 44, driven by the motor 41 via a gear train, engages the ice-breaking engagement 514 of the latch 51, causing the latch 51 to... Figure 1A The lock bolt rotates counterclockwise in the view shown. Thus, when the latch brake 52 no longer blocks the latch 51, and the latch 51 cannot rotate counterclockwise by the spring due to freezing, the motor 41 pushes the latch 51 to rotate via the ice-breaking actuator 44, that is, the vehicle lock assembly 1 performs ice breaking.

[0063] Figure 1BAnother perspective view of a portion of the vehicle lock assembly 1 according to an embodiment of the present invention is shown, the view being approximately as follows: Figure 1A The reverse side of the view shown.

[0064] like Figure 1B As shown, the vehicle lock assembly 1 includes a first mechanism 91 and a second mechanism 92. The first mechanism 91 is coupled to a motor 41 and can be driven by the motor 41 to electrically engage the vehicle lock assembly 1. Figure 1A and Figure 1B In the illustrated embodiment, the first mechanism 91 may include the aforementioned engaging actuator 31 and gear transmission system. According to other embodiments of this disclosure (not shown), the first mechanism 91 may include other configured components to enable the vehicle lock assembly 1 to perform electrical engaging. For example... Figure 1B As shown, the first mechanism 91 also includes a first part 21. In Figure 1B In the view shown, the first portion 21 is located in the upper half of the vehicle lock assembly 1 and is formed as a separate component. According to an embodiment of the invention, the first portion 21 is configured to be driven by a motor 41.

[0065] Continue to refer to Figure 1B The second mechanism 92 of the vehicle lock assembly 1 includes a second part 22. Figure 1B In the view shown, the second part 22 is located in the lower half of the vehicle lock assembly 1 and is formed as a separate component. The second part 22 is configured to move between a second part unlock position (hereinafter referred to as the unlock position) and a second part lock position (hereinafter referred to as the lock position). In the unlock position, the second part 22 unlocks the vehicle lock assembly 1, and in the lock position, the second part 22 locks the vehicle lock assembly 1. According to an embodiment of the present invention, the second part 22 is configured such that, in some cases, the second part 22 can be driven by the first part 21, and in some cases, the second part 22 can be driven by manually operated related components.

[0066] According to an embodiment of the present invention, the vehicle lock assembly 1 includes a coupling mechanism 95, through which a first portion 21 and a second portion 22 are coupled to each other, such that the first portion 21 can drive the second portion 22 to move between an unlocked position and a locked position. Furthermore, the second portion 22 can also be driven independently of the first portion 21 (e.g., driven by a manually operated component) to decouple the first portion 21 and the second portion 22, and the second portion 22 can move to a new relative position and remain in that new relative position independently of the first portion 21. In other words, the second portion 22 can be driven independently of the first portion 21 in the locked position to decouple the first portion 21 and the second portion 22, and the second portion 22 can move to a position different from the locked position (e.g., the unlocked position) and remain in that position. Furthermore, the second portion 22 can be driven independently of the first portion 21 in the unlocked position to decouple the first portion 21 and the second portion 22, and the second portion 22 can move to a position different from the unlocked position (e.g., the locked position) and remain in that position.

[0067] According to an embodiment of the present invention, when the first part 21, the second part 22 and the coupling mechanism 95 are provided for the vehicle lock assembly 1 as described above, even if only a single power source (such as the single motor 41 described above and illustrated) is provided for the vehicle lock assembly 1, the vehicle lock assembly 1 can perform the locking, unlocking and electric engagement functions of the vehicle door, and ensure that manual locking and manual unlocking can be achieved in various situations, thereby improving security.

[0068] In the following, various aspects of the present invention will be described in detail to illustrate the implementation and multiple advantages of the invention.

[0069] Figure 2 It shows Figure 1A and Figure 1B The perspective view of the vehicle lock assembly 1 of the illustrated embodiment shows some components assembled together, specifically illustrating the gear transmission system in the vehicle lock assembly 1. The gear transmission system may include a worm gear 42, a front gear 43, a drive member 10, and a rear gear 40 (see also...). Figure 1A and Figure 1B According to an embodiment of the present invention, the gear transmission system may be part of the first mechanism 91. In other words, the first mechanism 91 may further include a worm gear 42, a front gear 43, a drive member 10, and a rear gear 40. Figure 2As shown, motor 41 drives worm gear 42. Worm gear 42 drives front gear 43. Specifically, front gear 43 is a double-layer gear, and worm gear 42 meshes with the large gear of front gear 43. Front gear 43 drives drive member 10, which is also a double-layer gear. Specifically, the small gear of front gear 43 meshes with the large gear of drive member 10. Drive member 10 drives rear gear 40. Specifically, rear gear 40 is a double-layer gear, and the small gear of drive member 10 meshes with the large gear of rear gear 40. Rear gear 40 drives ice-breaking actuator 44. Specifically, ice-breaking actuator 44 includes a gear section, and the small gear of rear gear 40 drives this gear section to rotate ice-breaking actuator 44. Figure 2 Also shown is a pull-in actuator 31 that is rotatably connected to the rear gear 40.

[0070] Figure 3 A perspective view showing some components of the vehicle lock assembly 1 according to an embodiment of the present invention assembled together is shown. Figure 4A and Figure 4B It shows Figure 3 The diagram shows the perspective views of each component. Figure 3 , Figure 4A and Figure 4B The diagram shows a drive member 10, a first portion 21, a second portion 22, a coupling member 61, and a coupling member drive member 66. (As shown) Figure 3 , Figure 4A and Figure 4B The first part 21 can be separated from the drive unit 10, and the second part 22 can be separated from the first part 21.

[0071] like Figure 3 , Figure 4A and Figure 4B As shown, the drive component 10 is a double-layer gear, with additional structures on its axial side for driving other components, such as the first drive part 21 and the electrically driven actuator 48 (see also...). Figure 1B and Figure 10 (Figure 11). An arcuate protrusion 12 is provided on the axial side of the drive member 10, with a notch 125 defined between its two ends. This arcuate protrusion 12 is specifically configured to drive the electrically driven actuator 48. A cylindrical protrusion 11 is also provided on the axial side of the drive member 10, which drives the first portion 21. The cylindrical protrusion 11 protrudes, for example, from the arcuate protrusion 12 in the axial direction.

[0072] like Figure 3 , Figure 4A and Figure 4BAs shown, the first part 21 is rotatable about the first axis 81. The first part 21 has a recessed groove 215 on the side facing the drive member 10. When the first part 21 and the drive member 10 are assembled in place, the distance between the first part 21 and the drive member 10 is such that the cylindrical protrusion 11 extends into the first recess 215, while the arcuate protrusion 12 does not extend into the first recess 215.

[0073] like Figure 4B Specifically, the first portion of the groove 215 has an elongated shape, and has a first opening 2151 and a second opening 2152 at both ends of the elongated shape. When the drive member 10 rotates, causing the cylindrical protrusion 11 to move in a specific section of the first portion of the groove 215, the cylindrical protrusion 11 pushes the inner wall of the first portion of the groove 215, causing the first portion 21 to rotate within a specific angular range. According to an embodiment of the invention, the two ends of this specific angular range of the first portion 21 can be referred to as the first portion locked position and the first portion unlocked position, respectively. In other words, according to an embodiment of the invention, the drive member 10 can drive the first portion 21 to swing between the first portion locked position and the first portion unlocked position.

[0074] like Figure 3 , Figure 4A and Figure 4B As shown, the second part 22 is rotatable about the first axis 81. In other words, in this embodiment, the first part 21 and the second part 22 are separate components, coaxially arranged, and configured to rotate about the first axis 81 fixed in the vehicle lock assembly 1. However, according to other embodiments of the invention, the first part 21 and the second part 22 may also rotate about other axes fixed relative to the housing of the vehicle lock assembly 1. As previously described, the second part 22 is configured to move between an unlocked position (i.e., the second part unlocked position) and a locked position (i.e., the second part locked position). Refer to Figure 3 , Figure 4A and Figure 4B The second part 22 is configured to rotate within a specific angular range, the two ends of which can respectively define a locked position and an unlocked position. Thus, the second part 22 can move between the unlocked position and the locked position.

[0075] Also refer to Figure 1B The second part 22 includes a second part body 220 and a first branch 221, a second branch 222, and a third branch 223 extending from the second part body 220. According to an embodiment of the present invention, the first branch 221 can be engaged and driven by the inner handle transmission member 64, the second branch 222 can be engaged and driven by the mechanical lock connector 63, and the third branch 223 can be engaged and driven by the emergency lock 72.

[0076] According to an embodiment of the invention, the first branch 221 can be engaged and driven by the inner handle transmission member 64. For example, when the second part 22 is in the locked position, Figure 1B In the view, when the inner handlebar drive 64 rotates counterclockwise about the fourth axis 84, the inner handlebar drive 64 pushes the first branch 221, for example, the end of the first branch 221. For example, the inner handlebar drive drive portion 641 of the inner handlebar drive 64 pushes a protrusion on the end of the first branch 221, causing the second portion 22 to move from the locked position to the unlocked position. For example, the inner handlebar drive 64 is a sheet-like part having a body disposed around the fourth axis 84, and the inner handlebar drive drive portion 641 is a branch extending from the body of the inner handlebar drive 64.

[0077] According to an embodiment of the present invention, the vehicle lock assembly 1 further includes a mechanical lock connector 63, and the second branch 222 can be engaged and driven by the mechanical lock connector 63. Figure 1B A mechanical lock connector 63, driven by the mechanical lock of the vehicle door, is shown. Specifically, the mechanical lock connector 63 has a rod shape and is rotatable about a third axis 83. Figure 1B In the view, the mechanical lock connector 63 is configured to be mechanically actuated at its upper end, causing the entire mechanical lock connector 63 to swing between its own locked and unlocked positions. The mechanical lock connector 63 can act on the second branch 222, for example, on the end of the second branch 222, to drive the second portion 22 from the locked position to the unlocked position or vice versa. The mechanical lock connector 63 is configured to actuate the second branch 222 at its lower end (e.g., actuate the end of the second branch 222), causing the second portion 22 to switch between the locked and unlocked positions. Figure 1B In the view shown, the mechanical lock connector 63 extends from the upper half to the lower half of the vehicle lock assembly 1 to transmit the state change of the mechanical lock located in the upper half of the vehicle lock assembly 1 to the second part 22. For example, as Figure 1B As shown, see also Figure 3 , Figure 4A and Figure 4B The second branch 222 and the first branch 221 extend in directions away from each other.

[0078] According to an embodiment of the present invention, the vehicle lock assembly further includes an emergency lock 72, and the third branch 223 can be engaged and driven by the emergency lock 72. Figure 1B Emergency lock 72 is shown. Emergency lock 72 is located on the side of the fish-mouth portion of the vehicle lock assembly 1, and one side of it can be accessed from the outside of the vehicle lock assembly 1 at the fish-mouth portion for manual locking by the vehicle user, for example, when the battery for motor 41 is depleted. Figure 1B As shown, according to an embodiment of the present invention, the third branch 223 may extend toward the emergency lock 72. The emergency lock 72 can act on the third branch 223, for example, on the end of the third branch 223. Specifically, the emergency lock drive 721 of the emergency lock 72 can actuate the third branch 223 (e.g., actuate the end of the third branch 223) to move the second part 22 from the unlocked position to the locked position. For example, the emergency lock drive 721 is a tab extending from the body of the emergency lock 72.

[0079] Figure 3 Specifically, a coupling mechanism 95 is shown. As previously described, the first part 21 and the second part 22 can be coupled to each other via the coupling mechanism 95, such that the first part 21 can drive the second part 22 to move. Figure 3 , Figure 4A and Figure 4B In the illustrated embodiment, the first part 21 includes a coupling portion 251, which is an annular side surface facing radially outward relative to the first axis 81. The second part 22 includes a coupling mating portion 252, which is an arc-shaped side surface facing radially inward relative to the first axis 81. The coupling portion 251 and the coupling mating portion 252 contact each other and form a tightly fitted surface area, thereby forming a coupling mechanism 95. In other words, the coupling mechanism 95 is the tightly fitted surface area between the first part 21 and the second part 22, and the relative movement between the first part 21 and the second part 22 needs to overcome the frictional force generated in the tightly fitted surface area. For this purpose, for example, the first part 21 and the second part 22 can be made of materials such as polyoxymethylene (POM) or nylon, thereby having stable frictional performance.

[0080] Specifically, in Figure 3 , Figure 4A and Figure 4B In the illustrated embodiment, when one of the first part 21 and the second part 22 is fixed, if the force applied to the other of the first part 21 and the second part 22 cannot overcome the friction between the coupling part 251 and the coupling mating part 252 (i.e., the torque of the applied force relative to the first axis 81 is less than the torque of the friction generated by the tightly fitted surface area relative to the first axis 81), the one to which the force is applied will not rotate relative to the first axis 81. However, if the applied force can overcome the friction between the coupling part 251 and the coupling mating part 252 (i.e., the torque of the applied force relative to the first axis 81 is greater than or equal to the torque of the friction generated by the tightly fitted surface area relative to the first axis 81), the one to which the force is applied can rotate independently of the fixed one.

[0081] On the other hand, when one of the first part 21 and the second part 22 is not fixed, due to the arrangement of the coupling mechanism 95 shown in the figure, regardless of the magnitude of the force applied to the other part of the first part 21 and the second part 22, the part to which the force is applied can drive the other part to move, that is, rotate around the first axis 81 in this embodiment. In other words, the first part 21 and the second part 22 are separate components, but when the first part 21 and the second part 22 are coupled to each other, the first part 21 and the second part 22 can be coupled to each other as one through the coupling mechanism 95, so that the first part 21 and the second part 22 move as one.

[0082] It should be pointed out that, Figure 3 , Figure 4A and Figure 4B The illustrated embodiment is merely an exemplary embodiment of the present invention. Other configurations may be provided between the first portion 21 and the second portion 22 to impede relative movement between them through friction. For example, for a device with… Figure 3 , Figure 4A and Figure 4B The regions of the first part 21 and the second part 22 of the structure shown, which are configured to be tightly fitted to generate friction, may differ from the radially outer surface of the first part 21 and the radially inner surface of the second part 22, and may be other regions. Furthermore, according to the present invention, the embodiments of the coupling mechanism 95 are not limited to a tight fit, as will be detailed below.

[0083] Figure 5A and Figure 5B A perspective view of some components of the vehicle lock assembly 1 according to an embodiment of the present invention is shown, specifically showing the latch brake 52, the engaging member 61, the engaging member drive member 66, the inner handle connector 62, the inner handle transmission member 64, the outer handle connector 65, and the clutch 33.

[0084] See Figure 5A and Figure 5B As previously described, the latch brake 52 is configured to rotate about the second axis 82. The latch brake 52 is spring-biased, thereby... Figure 5A In the view, the latch brake 52 has a tendency to rotate counterclockwise within a certain angle range to keep the latch 51 in place. A brake drive portion 522 is fixedly provided on the latch brake 52, which is, for example, a protrusion extending from the side of the latch brake 52, such as a cylindrical protrusion. The engaging member 61 can engage the brake drive portion 522 to drive the latch brake 52 in place. Figure 5A Rotate clockwise in the view shown so that it no longer obstructs the latch 51.

[0085] See also Figure 4A and Figure 4B The coupling member 61 is rotatably connected to the coupling drive member 66 at its first end 613, for example, via a coupling shaft 616. The coupling member 61 has a coupling protrusion 612 and a coupling groove 611 at its second end 614 opposite to the first end 613. The coupling member 61 is configured to be driven by the second portion 22 via the coupling protrusion 612 to rotate about the coupling shaft 616. The coupling member 61 is configured to drive the latch brake 52 via the coupling groove 611. For example, the coupling protrusion 612 and the coupling groove 611 are located on opposite sides of the coupling member 61.

[0086] Specifically, in Figure 5A In the view, the coupling 61 is spring-biased at the coupling pivot 616 to have a tendency to rotate counterclockwise within a certain angular range. See also... Figure 4B The second part 22 has a stop wall 225 at a position corresponding to the engaging member protrusion 612. Under the action of spring bias, the engaging member 61 abuts against the stop wall 225 via the engaging member protrusion 612 (see also...). Figures 6A to 6D Therefore, the movement of the second part 22 between the unlocked and locked positions drives the rotational oscillation of the engaging member 61 relative to the engaging member pivot 616. Figure 5A In the view, when the second part 22 moves from the locked position to the unlocked position, the second end 614 of the coupling 61 moves in a direction generally toward the second axis 82 (i.e., moves in the engagement direction), and when the second part 22 moves from the unlocked position to the locked position, the second end 614 of the coupling 61 moves in a direction generally away from the second axis 82 (i.e., moves against the engagement direction).

[0087] See also Figures 4A to 5B The engagement groove 611 is provided on the side of the engagement member 61 facing the latch brake member 52, and is recessed into the surface of that side. The engagement groove 611 has an elongated shape and is open at one end to receive the brake drive portion 522 of the latch brake member 52 through the opening.

[0088] In other words, in Figure 5A In the view, when the second end 614 of the coupling 61 moves in a direction generally toward the second axis 82, the brake member driven part 522 of the latch brake 52 enters the coupling groove 611 from the aforementioned opening (as shown in the image). Figure 5B As shown), the engaging member 61 engages the latch brake member 52, and the vehicle lock assembly 1 accordingly enters the unlocked state. With the brake driven portion 522 in the engaging member groove 611, by moving the engaging member 61 in a direction intersecting the aforementioned engagement direction (e.g., in...), Figure 5AIn the process, the engaging member drive member 66 pulls the engaging member 61 in a generally downward direction, pushing the brake member driven part 522 against the inner wall of the engaging member groove 611, thereby driving the locking tongue brake member 52 in... Figure 5A Rotate clockwise in the view shown.

[0089] On the other hand, Figure 5A In the view, when the second end 614 of the engagement member 61 moves in a direction substantially away from the second axis 82, the engagement member 61 moves against the engagement direction to disengage from the latch brake 52, and the brake driven part 522 exits the engagement groove 611 from the opening of the engagement member groove 611. Thereafter, movement of the engagement member 61 in a direction intersecting the engagement direction cannot drive the latch brake 52, and the vehicle lock assembly 1 accordingly enters the locked state.

[0090] See also Figure 5A and Figure 5B The vehicle lock assembly 1 also includes an inner handle connector 62 driven by the inner handle of the door. The inner handle connector 62 is configured to rotate about an inner handle connector pivot 620. The inner handle connector 62 includes an inner handle connector driven portion 622, which is driven to rotate by the inner handle of the door, for example, via a cable drive. The inner handle connector 62 includes a door opening drive portion 623, which is configured to push a first driven portion 662 of the engagement member drive portion 66 (see [link]). Figure 5B The engagement drive 66 is configured to rotate about a fourth axis 84. The first driven part 662 and the engagement shaft 616 are located on opposite sides of the fourth axis 84. The inner handle connector 62 pushes the engagement drive 66, causing the engagement shaft 616 to rotate... Figure 5A The view shown moves approximately downwards. Therefore, when the brake member driven portion 522 is in the engagement member groove 611, i.e., when the vehicle lock assembly 1 is in the unlocked state, the inner handle connector 62 drives the engagement member 61 via the engagement member drive member 66, which in turn drives the latch brake member 52, causing the latch brake member 52 to no longer block the latch 51, thus opening the vehicle door. Alternatively, according to an embodiment not shown in this disclosure, other configured components or assemblies may be provided such that when the engagement member 61 engages with the latch brake member 52, the inner handle of the vehicle door drives the engagement member 61 to cause the engagement member 61 to drive the latch brake member 52.

[0091] See also Figure 5A and Figure 5B The vehicle lock assembly 1 also includes an outer handle connector 65 driven by the outer handle of the vehicle door. The outer handle connector 65 is configured to rotate about a fourth axis 84. The outer handle connector 65 includes an outer handle connector driven portion 652, which is driven by the outer handle of the vehicle door, for example, via a cable drive. Figure 5ARotating clockwise in the view shown. The outer handle connector 65 includes an outer handle connector drive portion 651, which is configured to push a second driven portion 664 of the engagement drive portion 66. Figure 5A As shown, both the driven portion 652 and the driving portion 651 of the outer handle connector are located at the distal end of the outer handle connector 65 relative to the fourth axis 84. According to an embodiment of the invention, when the inner handle connector 62 drives the engaging member 66... Figure 5A When rotated clockwise in the view shown, the outer handle connector 65 does not move with the engagement drive 66, thus preventing the outer handle of the door from performing the corresponding door opening action.

[0092] Figure 5A The inner handlebar drive 64 is shown again. The inner handlebar drive 64 is configured to drive the second part 22 via the inner handlebar connector 62. (See attached image.) Figure 5A As shown, the inner handle connector 62 also includes an unlocking drive portion 621, which may include, for example, a ball. The inner handle transmission 64 also includes an inner handle transmission driven portion 642, which is another branch extending from the main body of the inner handle transmission 64. This other branch extends along a branch defined away from the inner handle transmission drive portion 641, for example, generally along the axis of the fourth axis 84. When the inner handle of the door is pulled, the inner handle connector 62 rotates about the inner handle connector pivot 620, and the unlocking drive portion 621 moves in a direction generally out of the paper. The unlocking drive portion 621, thus moving, presses the inner handle transmission driven portion 642, causing the inner handle transmission 64 to move about the fourth axis 84. Figure 5A In the view shown, counterclockwise rotation pushes the first branch 221 (e.g., the end of the first branch 221). Consequently, the inner handle connector 62 acts on the first branch 221 via the inner handle transmission 64 to drive the second portion 22 from a locked position to an unlocked position. According to the invention, the inner handle connector 62 is spring-biased to rotate only when driven by the inner handle of the door to drive the inner handle transmission 64. Furthermore, the inner handle transmission 64 is spring-biased to rotate only when driven by the inner handle connector 62 to drive the second portion 22. Alternatively, according to an embodiment not shown in this disclosure, other configured components or parts may be provided such that the inner handle of the door drives the second portion 22 from a locked position to an unlocked position via the first branch 221.

[0093] Figures 6A to 6D A side view of a portion of a vehicle lock assembly 1 according to an embodiment of the present invention is shown, illustrating the first portion 21 and the second portion 22 in different positions, to explain the unlocking and locking methods of the vehicle lock assembly 1 according to the present invention. It should be noted that... Figures 6A to 6DSubsequent Figures 7 to 10 In the side view shown, some parts are set to be semi-transparent to show the structure on their back and the parts behind them.

[0094] According to an embodiment of the present invention, the rotational position of the first portion 21 can be defined by the rotational position of the driving member 10. As previously described, by rotating the driving member 10, the cylindrical protrusion 11 moves within a specific section of the first portion groove 215 to drive the first portion 21 to move between a first portion locked position and a first portion unlocked position. In the embodiment illustrated in the present invention, the rotational position of the driving member 10 defines the driving member stroke, which includes a locking point and an unlocking point, each corresponding to a specific rotational position of the driving member 10. When the driving member 10 rotates from the locking point to the unlocking point, the driving member 10 drives the first portion 21 from the first portion locked position to the first portion unlocked position. When the driving member 10 rotates from the unlocking point to the locking point, the driving member 10 drives the first portion 21 from the first portion unlocked position to the first portion locked position.

[0095] exist Figure 6A In the first part 21, the first part is in the locked position, and the second part 22 is in the locked position (i.e., the second part is in the locked position). As mentioned earlier, in Figure 6A In the middle, the engaging member 61 is not engaged with the locking tongue brake member 52. If in Figure 6A In the event of pulling the outer or inner handle of the door to drive the engagement piece 61 Figure 6A Moving downwards in the view shown, the engaging member 61 cannot drive the locking tongue brake member 52. Figure 6A In the view shown, rotating clockwise prevents the door from opening. In other words, the second part 22, in the locked position, locks the door lock assembly 1.

[0096] exist Figure 6B In the middle, the first part 21 is in the first part unlocked position, and the second part 22 is in the unlocked position (i.e., the second part unlocked position). From Figures 6A to 6B The state transition can be accomplished by rotating the drive element 10 from the locking point to the unlocking point. Figure 6A and Figure 6B In the view, the drive member 10 rotates clockwise from the locking point to the unlocking point. Specifically, by rotating the drive member 10, the cylindrical protrusion 11 of the drive member 10 pushes the inner wall of the first portion groove 215 of the first portion 21, causing the first portion 21 to rotate to the first portion unlock position. On the other hand, in Figure 6A In this process, the clockwise rotation of the second part 22 is unimpeded. Therefore, the rotation of the first part 21 causes the second part 22 to move from the locked position to the unlocked position. Figure 6B In the view, if the outer or inner handle of the door is pulled to drive the engagement 61, Figure 6BMoving downwards in the view shown, the engaging member 61 can drive the locking tongue brake member 52 in... Figure 6B The door opens by rotating it clockwise in the view shown (see also...). Figure 7 In other words, the second part 22, in the unlocked position, unlocks the vehicle lock assembly 1.

[0097] from Figures 6B to 6A The state transition can be accomplished by rotating the drive member 10 from the unlock point to the lock point. During the rotation of the drive member 10 from the unlock point to the lock point, the first part 21 rotates from the first part unlock position to the first part lock position. On the other hand, in Figure 6B In this configuration, the counterclockwise rotation of the second part 22 is unimpeded. Therefore, the rotation of the first part 21 causes the second part 22 to move from the unlocked position to the locked position. In other words, the drive unit 10 can drive the second part 22 to move between the unlocked and locked positions by driving the first part 21.

[0098] exist Figure 6C In the middle, the first part 21 is in the locked position, and the second part 22 is in the unlocked position (i.e., the unlocked position of the second part). From Figures 6A to 6C The state transition can be accomplished by manually driving the second part 22 independently. For example, by pulling the inner handle of the door or unlocking the mechanical lock of the door, the corresponding connecting piece pushes the corresponding branch of the second part 22 to decouple the first part 21 and the second part 22, thereby driving the second part 22 independently of the first part 21, allowing the second part 22 to move independently relative to the first part 21. In other words, in the illustrated embodiment, the force required to independently drive the second part 22 is greater than the frictional force that needs to be overcome to generate relative motion between the first part 21 and the second part 22. After moving independently relative to the first part 21, the second part 22 can maintain its new relative position with respect to the first part 21.

[0099] The applicant discovered that, in cases where a single motor 41 is needed to control the locking, unlocking, and electric engagement of the vehicle lock assembly 1, a high reduction ratio is required from the motor 41 to the drive component 10 to output high force (e.g., for electric engagement) while miniaturizing the vehicle lock assembly 1. In this situation, if a conventional method is used, establishing a continuous and uninterrupted transmission relationship between the motor 41 and the locking and unlocking components (such as the engagement component 61 in this disclosure), it becomes practically difficult to manually drive the locking and unlocking components, making manual locking or unlocking difficult. This is because the aforementioned high reduction ratio gives the transmission system a certain self-locking characteristic. When the motor is not working, the driving force for manually operating the locking and unlocking components is simultaneously transmitted to the motor's output shaft via the aforementioned transmission relationship; however, passively rotating the motor requires considerable force. Furthermore, in cases of motor failure or vehicle power failure, the motor is even more difficult to passively rotate, making it impossible to manually release the locked state of the vehicle lock assembly 1, posing a significant safety hazard.

[0100] Therefore, in the vehicle lock assembly 1 according to the present invention, due to the aforementioned first part 21, second part 22, and coupling mechanism 95, when the first part 21 is in the first part locked position, the second part 22 can be moved from the locked position to the unlocked position only by overcoming the relatively small resistance encountered in decoupling the first part 21 and the second part 22, without having to overcome the larger resistance that ultimately causes the motor 41 to rotate passively. Furthermore, even if the motor fails or the vehicle loses power, the locked state of the vehicle lock assembly 1 can be manually released, effectively improving vehicle security.

[0101] According to an embodiment of the present invention, after the second part 22 moves to the unlocked position, it cannot continue to move away from the locked position. Therefore, from... Figure 6C Starting from the condition, by moving the drive member 10 from the locking point to the unlocking point, the drive member 10 can overcome the force between the first part 21 and the second part 22 to drive the first part 21 to move independently of the second part 22, so that the first part 21 moves from the first part's locked position to the first part's unlocked position, thereby restoring coupling between the first part 21 and the second part 22, returning to the starting point. Figure 6BThe displayed state. In other words, according to an embodiment of the present invention, the force by which the driving member 10 drives the first part 21 is greater than the frictional force that needs to be overcome to generate relative movement between the first part 21 and the second part 22, even if the force by which the first part 21 is driven independently of the second part 22 is greater than the frictional force that needs to be overcome to generate relative movement between the first part 21 and the second part 22. Therefore, when the second part 22 is in a new relative position (here, the new relative position is the unlocked position of the second part 22), the first part 21 can be driven independently of the second part 22 to restore the coupling between the first part 21 and the second part 22. Thereafter, the driving member 10 can continue to drive the second part 22 to move via the first part 21 to control the unlocking and locking of the vehicle lock assembly 1, that is, the first part 21 and the second part 21 are coupled together.

[0102] exist Figure 6D In the middle, the first part 21 is in the first part unlocked position, and the second part 22 is in the locked position (i.e., the second part locked position). Figure 6D The situation shown can be achieved through Figure 6B The situation shown is achieved through manual operation, for example, by locking the mechanical lock on the door or locking the emergency lock 72 on the door. The principle is the same as described in the vehicle lock assembly 1. Figures 6A to 6C The process of change will not be elaborated here. Furthermore, according to an embodiment of the present invention, in the second part 22 from... Figure 6B Move to Figure 6D Once locked, it cannot move further away from the unlocked position. Therefore, from... Figure 6D Starting from the condition, by moving the drive member 10 from the unlocking point to the locking point, the drive member 10 can overcome the force between the first part 21 and the second part 22 to drive the first part 21 to move independently of the second part 22, so that the first part 21 moves from the first part unlocking position to the first part locking position, thereby restoring coupling between the first part 21 and the second part 22, returning to the previous state. Figure 6A The displayed state. Therefore, when the second part 22 is in a new relative position (here, the new relative position is the locked position of the second part 22), the first part 21 can be driven independently of the second part 22 to restore the coupling between the first part 21 and the second part 22. Thereafter, the drive member 10 can continue to drive the second part 22 to move via the first part 21 to control the unlocking and locking of the vehicle lock assembly 1, that is, the first part 21 and the second part 22 are coupled together.

[0103] Figure 7 A side view of a portion of a vehicle lock assembly 1 according to an embodiment of the present invention is shown, illustrating the state in which the pulling of the door handle is transmitted to the vehicle lock assembly 1 when the second portion 22 is in the unlocked position. Figure 7 Specifically, the outer door handle is pulled, thereby pushing the engagement drive 66 in the outer handle connector 65. Figure 7 In the view shown, rotating clockwise around the fourth axis 84, the coupling drive 66 drives the coupling 61 in... Figure 7 In the view shown, it moves approximately downwards. The engaging member 61 then actuates the latch brake 52, preventing it from obstructing the latch 51. The latch 51 is... Figure 7 The view shown allows for clockwise rotation to push out the locking pin and open the door.

[0104] Figures 8A to 8B A side view of a portion of a vehicle lock assembly 1 according to an embodiment of the present invention is shown, illustrating the electric engagement function of the vehicle lock assembly 1.

[0105] Figure 8A This shows a state where the vehicle lock assembly 1 is performing electric engagement. For example... Figure 8A As shown, the driving component 10 is in a different position from Figure 6A and Figure 6B The rotational position shown (e.g., referring to the position of cylindrical protrusion 11). Relative to Figure 6B The drive member 10 rotates further clockwise, and the cylindrical protrusion 11 of the drive member 10 moves towards the first opening 2151 in the first portion of the groove 215. Then, the drive member 10 continues to rotate, and the cylindrical protrusion 11 moves out of the first opening 2151 from the first portion of the groove 215, as... Figure 8B As shown.

[0106] During the electric engagement process of the vehicle lock assembly 1, the drive component 10 moves from... Figure 6B Rotate to the state shown Figure 8A The state shown is then rotated further to... Figure 8B The state shown. During this process, the drive unit 10 drives the subsequent gear 40 in... Figure 8A The rotation is counterclockwise in the view shown. A pull-in drive shaft 32 is provided on the stage gear 40, and the pull-in drive shaft 32 is driven by the drive member 10 to move along the pull-in path. For example, in... Figure 8A and Figure 8B In the middle, the attraction path extends roughly to the upper left. An attraction actuator 31 is rotatably connected to the attraction drive shaft 32. The attraction actuator 31 is a rotating arm, one end of which is rotatably connected to the attraction drive shaft 32. The attraction actuator 31 is spring-biased at the attraction drive shaft 32 to have a certain angular range. Figure 8A The view shown shows a clockwise rotation tendency. As the pull-in drive shaft 32 moves along the pull-in path, it causes the pull-in actuator 31 to move as a whole along the pull-in path. Consequently, the arm 310 of the pull-in actuator 31 approaches the latch 51, and then pushes the latch 51 to rotate. Specifically, the protrusion 311 on the arm 310 of the pull-in actuator 31... Figure 8A The engaging part 513 is close to the locking tongue 51 and in Figure 8BThe locking tongue 51 is pushed at the protruding engaging joint 513 so that the locking tongue 51 is in Figure 8B In the view shown, rotating counterclockwise to the fully closed position completes the electric closing (see also...). Figure 8C ).

[0107] According to an embodiment of the present invention, as described above, both the drive member 10 and the rear gear 40 are gears that mesh with each other, and the transmission ratio between the drive member 10 and the rear gear 40 is greater than 3, so as to increase the output torque of the rear gear 40 in driving the electric engagement and the ice-breaking process described later. On the other hand, by configuring the vehicle lock assembly 1 to be driven by the drive member 10 for locking and unlocking, and driven by the rear gear 40 of the drive member 10 for electric engagement, high time efficiency in the transition between locking and unlocking is ensured.

[0108] According to an embodiment of the present invention, the rotational section of the aforementioned drive member 10 that causes the vehicle lock assembly 1 to perform electric engagement can be called the engagement section. In other words, the movement of the drive member 10 in the engagement section enables the vehicle lock assembly 1 to perform electric engagement. According to an embodiment of the present invention, the direction in which the drive member 10 moves from the locking point to the unlocking point can be called the first stroke direction. During the drive member's stroke, the locking point, unlocking point, and engagement section can be sequentially arranged along the first stroke direction. When the drive member 10 moves along the first stroke direction in the engagement section, the drive member 10 causes the vehicle lock assembly 1 to perform electric engagement. Thus, when the first part 21 and the second part 22 are coupled together, the drive member 10, on the one hand, positions the first part 21 in the first unlocked position so that the second part 22 is in the unlocked position, and on the other hand, begins to drive the electric engagement-related components to perform electric engagement. Thus, during the electric engagement of the vehicle lock assembly 1, it is ensured that manual operation can drive the bolt brake 52 to rotate without obstructing the bolt 51, providing convenience for manual intervention to prevent the door from closing during the electric engagement process.

[0109] As previously mentioned, the vehicle lock assembly 1 also includes a clutch element 33. See also Figure 5A and Figure 5B The clutch 33 is rotatable about a fifth axis 85 and includes a first arm 333 and a second arm 334 extending in substantially opposite directions from the position of the fifth axis 85. The clutch 33 is spring-biased to have a certain angular range. Figure 8C The view shown shows a tendency to rotate clockwise. The engagement drive 66 also includes a clutch drive 663, which abuts against the second arm 334 of the clutch 33 to resist the tendency of the clutch 33 to rotate further clockwise.

[0110] Compare Figure 8C and Figure 8DDuring the electric engagement of the door assembly 1, when the pull of the door handle is transmitted to the lock assembly 1, the clutch drive part 663 of the engagement drive part 66... Figure 8D In the view shown, the clutch moves approximately downwards to slide relative to the second arm 334 of the clutch 33, while simultaneously driving the clutch 33 to rotate counterclockwise. Thus, the end of the first arm 333 of the clutch 33, acting as the clutch drive unit 331, pushes the arm 310 of the engagement actuator, driving the engagement actuator 31 to rotate relative to the engagement drive shaft 32, causing the arm 310 of the engagement actuator to move away from the latch 51 to disengage from the latch 51. Figure 8D As can be seen, the protrusion 311 of the arm portion 310 of the engaging actuator disengages from the engaging engagement portion 513 of the latch 51. According to an embodiment of the present invention, the arm portion 310 of the engaging actuator is provided with a track portion 315, and the clutch drive portion 331 slides along the track portion 315 while pushing the arm portion 310 of the engaging actuator.

[0111] like Figure 8C and Figure 8D As shown, according to an embodiment of the present invention, during the electric closing process of the door assembly 1, pulling the door handle simultaneously drives the latch brake 52 to prevent it from obstructing the latch 51 and drives the closing actuator 31 to disengage from the latch 51, ensuring the door opens and effectively improving the safety of the electric closing process. See also... Figure 4B The first opening 2151 of the first component groove 215 of the first component 21 has an enlarged opening shape. Therefore, when the drive member 10 returns from the engaging section to the unlocking point, no matter what position the first component 21 is in, the cylindrical protrusion 11 of the drive member 10 can enter the first component groove 215 from the first opening 2151, so that the vehicle lock assembly 1 can continue to work normally.

[0112] Figure 9 A side view of a portion of a vehicle lock assembly 1 according to an embodiment of the present invention is shown, illustrating the vehicle lock assembly 1 in a state of electrical release, i.e., the door is opened solely by the motor 41. For clarity, Figure 9 Some components have been omitted. For example... Figure 9As shown, the electric release is performed by the drive member 10 driving the electric drive actuator 48. Accordingly, the drive member 10 has an electric release section within its stroke, such that the electric release section, locking point, unlocking point, and engaging section are sequentially arranged along the first stroke direction. When the first part 21 and the second part 22 are coupled together, when the drive member 10 moves along the second stroke direction opposite to the first stroke direction in the electric release section, the drive member 10 causes the vehicle lock assembly 1 to perform an electric release. This arrangement effectively separates the strokes of the drive member 10 for each function, while making the structure and arrangement of related components in the vehicle lock assembly 1 more rational and simplified. Furthermore, when the first part 21 and the second part 22 are coupled together, when the drive member 10 moves from the locking point to the electric release section and moves within the electric release section along the second stroke direction, the second part 22 is in the locked position. This arrangement effectively simplifies the structure and arrangement of the drive member 10 and other related components, facilitating the manufacture of the vehicle lock assembly.

[0113] Figure 9 Specifically, an electrically driven actuator 48 is shown. The electrically driven actuator 48 is rotatable about a sixth axis 86 and is spring-biased to move within a certain angular range. Figure 9 The view shown exhibits a tendency to rotate counterclockwise. The electrically driven actuator 48 is a single rigid body component having a generally upwardly extending first arm 483 and a generally downwardly extending second arm 484, wherein the end of the first arm 483 defines a driven portion 482 of the electrically driven actuator, and the end of the second arm 484 defines a driven portion 481 of the electrically driven actuator. See also Figure 6A and Figure 6B When the drive member 10 is at the locking or unlocking point, the rotational position of the electric drive actuator 48 causes the driven portion 482 of the electric drive actuator to extend into the notch 125 formed by the arcuate protrusion 12 of the drive member 10. When the drive member 10 rotates counterclockwise from the locking point, the drive member 10 moves towards the electrically released section along the second stroke direction and moves within the electrically released section. During this process, the drive portion 121 of the drive member 10, defined by the arcuate protrusion 12 and the notch 125, pushes the driven portion 482 of the electric drive actuator, causing the electric drive actuator 48 to... Figure 9 Rotating clockwise in the view shown. Correspondingly, the electric drive actuator drive unit 481 located at the lower end of the electric drive actuator 48 pushes the brake driven unit 522 of the latch brake member 52, causing the latch to... Figure 9 In the view shown, the door is opened by rotating clockwise. During this process, the surface of the electric drive actuator drive unit 481 slides relative to the side of the cylindrical brake driven unit 522. Figure 9 In the embodiment shown, the electric drive actuator 48 is driven by the drive member 10, which improves the time efficiency of the door electric release.

[0114] Figure 10 A side view of a portion of a vehicle lock assembly 1 according to an embodiment of the present invention is shown, illustrating the vehicle lock assembly 1 in the process of ice breaking. For clarity, Figure 10 Some parts have been omitted. (Compared to...) Figure 9 As shown, in Figure 10 In this configuration, the drive member 10 rotates further counterclockwise to move along the second stroke direction in the ice-breaking section, causing the vehicle lock assembly 1 to perform ice breaking. In other words, during the drive member's stroke, an ice-breaking section, an electric release section, a locking point, an unlocking point, and a latching section are sequentially arranged along the first stroke direction. When the first part 21 and the second part 22 are coupled together, the drive member 10 causes the vehicle lock assembly 1 to perform ice breaking when it moves along the second stroke direction in the ice-breaking section. This configuration effectively separates the strokes of the drive member 10 in performing each function, while making the structure and arrangement of related components in the vehicle lock assembly 1 more rational and simplified. Furthermore, the drive member 10 and the first part 21 are configured such that, when the first part 21 and the second part 22 are coupled together, the second part 22 is in the locked position when the drive member 10 moves along the second stroke direction from the electric release section to the ice-breaking section and moves within the ice-breaking section. This configuration effectively simplifies the structure and arrangement of the drive member 10 and other related components, facilitating the manufacturing of the vehicle lock assembly.

[0115] It should be noted that, according to an embodiment of the present invention, during the movement of the drive member 10 along the second stroke direction in the electrically released section and / or ice-breaking section, the second part 22 is in the locked position by default. However, during the movement of the drive member 10 along the second stroke direction in the electrically released section and / or ice-breaking section, if the pull of the inner handle of the door is transmitted to the door lock assembly 1, the second part 22 is driven by the inner handle of the door to move to the unlocked position.

[0116] As mentioned above, see also Figure 1A and Figure 2 The ice-breaking actuator 44 is driven by a motor 41 via a gear transmission system. The power output from the motor 41 is transmitted sequentially to the ice-breaking actuator 44 through a worm gear 42, a front gear 43, a drive member 10, and a rear gear 40. When the drive member 10 moves along the second stroke direction in the ice-breaking section, the ice-breaking actuator 44... Figure 10 When rotated counterclockwise in the view shown, its hook-shaped ice-breaking actuator 441 engages with and pushes the protruding ice-breaking engagement 514 of the locking tongue 51, causing the locking tongue 51 to... Figure 10 Rotate clockwise in the view shown to perform ice breaking.

[0117] It should be noted that, regarding the ice-breaking mechanism of the vehicle lock assembly 1, the rear gear 40 meshes with the ice-breaking actuator 44, and the gear ratio is greater than 1, for example, greater than 3, to further increase the torque output by the ice-breaking actuator 44 during ice breaking. Furthermore, it should be noted that, if... Figure 10 As shown, due to the structure of the arc-shaped protrusion 12 on the drive member 10, when the drive member 10 moves in the ice-breaking section, the electrically driven actuator 48 remains in contact with the radial outer surface of the arc-shaped protrusion 12, thereby holding the latch brake 52 in the position of not stopping the latch 51, ensuring smooth ice breaking. According to an embodiment of the present invention, the arc-shaped protrusion 12 extends along an arc segment centered on the center of the drive member 10.

[0118] The foregoing description only describes some embodiments according to the present invention. According to other embodiments of the present invention, the components in the vehicle lock assembly 1 may have other specific configurations. Furthermore, according to other embodiments of the present invention, the coupling mechanism 95 may be implemented in different ways.

[0119] For example, according to some embodiments of the invention, the first part 21 and the second part 22 are still separate components, coaxially arranged and configured to rotate about a first axis 81 fixed in the vehicle lock assembly 1. However, the coupling mechanism 95 consists of a latching portion provided on the first part 21 and a mating latching portion provided on the second part 22 that latches with the latching portion. In the vehicle lock assembly 1, the force that drives the second part 22 independently of the first part 21 is greater than the force that disengages the latching portion from the mating latching portion. Furthermore, the force that drives the first part 21 with the driving member 10 is greater than the force that latches the latching portion from the mating latching portion; that is, the force that drives the first part 21 to recouple from the second part 22 is greater than the force that latches the latching portion from the mating latching portion.

[0120] According to the above embodiment, the first part 21 and the second part 22 can be coupled together by the coupling mechanism 95, that is, they can move as a whole, so that the drive member 10 can drive the second part 22 to move between the unlocked position and the locked position by driving the first part 21. Furthermore, the second part 22 can be driven independently to decouple the first part 21 and the second part 22, and the second part 22 can move independently relative to the first part 21 and maintain a new relative position. In other words, the second part 22 can be manually disengaged from the first part 21, and the second part 22 can be driven to move independently of the first part 21 to manually unlock or lock the vehicle lock assembly 1. Subsequently, the drive member 10 can move the first part 21 to engage with the second part 22. Afterwards, the drive member 10 still drives the second part 22 to move between the unlocked position and the locked position by driving the first part 21.

[0121] According to some embodiments of the invention, the first part 21 and the second part 22 are still separate components; however, the first part 21 and the second part 22 are configured to move individually or jointly along other specific trajectories.

[0122] According to some embodiments of the present invention, the first part 21 and the second part 22 may each be part of a single deformable component, and the vehicle lock assembly 1 includes a coupling mechanism 95.

[0123] Figure 11A A schematic diagram of the coupling mechanism 95 of the vehicle lock assembly 1 according to another embodiment of the present invention is shown. Figures 11B to 11F Side views of the coupling mechanism 95 in different states are shown. It should be noted that... Figures 11A to 11F The coupling mechanism 95 shown can be coupled with Figures 1A to 10 Other parts or components of the illustrated vehicle lock assembly 1 may be combined or modified without exceeding the scope of the invention.

[0124] Figure 11A The drive member 10 of the vehicle lock assembly 1 is shown in a simplified manner. The drive member 10 is configured to rotate about a third axis 83. For example, the vehicle lock assembly 1 includes a fixed base 23 on which a first base shaft 231 is provided, and the drive member 10 is rotatably mounted on the first base shaft 231. However, the drive member 10 may also be configured to rotate about other axes fixed relative to the vehicle lock assembly 1. Figure 11A A first portion 21 of the first mechanism is also shown, which is the drive member 10. Furthermore, depending on the definition and specific construction of the drive member 10, the first portion 21 may also be formed as part of the drive member 10. In the above case, the first portion 21 can be configured to move integrally with the drive member 10. Figure 11A Specifically, the first portion 21 may include a cylindrical protrusion 13 that protrudes from the surface of the drive member 10.

[0125] Figure 11AA second part 22 of the second mechanism is also shown, which is a separate component from the first part 21. The second part 22 has an elongated hole 227 that fits onto a second base shaft 232 disposed on the base 23. The second part 22 is capable of rotating about the second base shaft 232 within a certain range, which is defined, for example, by a structure (not shown) of the lock assembly 1. The second part 22 is also capable of moving relative to the second base shaft 232 within a certain range, which is defined by the positional relationship between the elongated hole 227 and the second base shaft 232. Furthermore, the second part 22 is configured to be subjected to a spring force 24 (indicated by a bold arrow in the drawing) generally along the path from the second base shaft 232 to the first base shaft 231, which is applied, for example, by a spring (not shown) disposed in the lock assembly 1. One end of the second part 22 is close to and spaced apart from the first base shaft 231. This end of the second part 22 is a tapered end 226, which has a decreasing cross-sectional area in the direction near the end. In various operating states of the vehicle lock assembly 1, the tapered end 226 of the second part 22 can approach the cylindrical protrusion 13 of the first part 21 in various relative positional relationships and can elastically abut against the cylindrical protrusion 13.

[0126] Figures 11B to 11E The relationship between the first part 21 and the second part 22 coupled to each other is illustrated, which exemplarily shows the first part 21 driving the second part 22 from the unlocked position (see reference). Figure 11B Move to the locked position (refer to) Figure 11E The process of ). In Figure 11B In the view shown, the tapered end 226 is located approximately to the left of the cylindrical protrusion 13. (Refer to...) Figure 11C Drive component 10 relative to Figure 11B As shown, rotating clockwise, the cylindrical protrusion 13 pushes the tapered end 226. Because the rotation angle of the second part 22 is limited, and the second part 22 elastically abuts against the cylindrical protrusion 13 via the tapered end 226, in... Figure 11C In the view shown, the second part 22 is offset in a generally downward direction by the cylindrical protrusion 13. (Refer to...) Figure 11D The drive component 10 continues to rotate clockwise, and the tapered end 226 passes over the cylindrical protrusion 13. Figure 11D In the view shown, the second part 22 moves in a generally upward direction due to the force of the elasticity 24. From Figures 11D to 11E The drive component 10 rotates counterclockwise, pushing the second part 22 to rotate clockwise, thereby moving the second part 22 from the unlocked position to the locked position. In a similar manner, the first part 21 can also drive the second part 22 from the locked position to the unlocked position. Thus, the first part 21 and the second part 22 are coupled to each other as shown in the diagram.

[0127] Refer to in sequence Figure 11E , Figure 11F and Figure 11B This describes how the second part 22 is driven independently of the first part 21 to decouple the aforementioned relationship between the first part 21 and the second part 22. Figures 11E to 11F The position of the driving component 10 remains unchanged, that is, the position of the first part 21 remains unchanged. On the other hand, from Figures 11E to 11F The second part 22 is independently driven (e.g., from a door handle, mechanical lock, emergency lock, etc., as described above). Since the first part 21 is configured to be driven by a power source, the second part 22 has difficulty pushing the first part 21 to move accordingly (i.e., the drive member 10 is difficult to rotate by the second part 22). Therefore, in the illustrated configuration, the second part 22 rotates counterclockwise on one hand and moves downwards in the illustrated view on the other due to the positional constraint of the cylindrical protrusion 13. Specifically, the tapered end 226 slides along the surface of the cylindrical protrusion 13 to pass over it. Figures 11F to 11B If the second part 22 continues to be driven independently, then the second part 22 will rotate counterclockwise on the one hand, and move upward in the illustrated view on the other hand due to the push of the elastic force 24. Thus, the second part 22 moves independently of the first part 21 from Figure 11E The locked position shown is moved to Figure 11B The first part 21 is moved to the unlocked position and remains in the unlocked position. Similarly, the second part 22 can also be driven independently of the first part 21, moving from the unlocked position to the locked position and remaining there. Once the second part 22 has moved to and remained in the new position, if the first part 21 is moved by a power source, the first part 21 and the second part 22 will recouple to each other.

[0128] It should be pointed out that, Figure 11A and Figure 11F The examples shown are merely illustrative embodiments. Figures 11A to 11F As shown, the first portion 21 includes a blocking structure (e.g., a cylindrical protrusion 13) to restrict movement of the second portion 22 relative to the first portion 21, such that the first portion 21 and the second portion 22 are coupled to each other, while when the second portion 22 is driven independently of the first portion 21, the second portion 22 moves to pass over the blocking structure to decouple the first portion 21 and the second portion 22. For example, as Figures 11A to 11F Specifically, the second portion 22 is capable of elastic movement relative to the first portion 21 (e.g., by applying a spring 24, not shown) such that when the second portion 22 is driven independently of the first portion 21, the second portion 22 slides along the surface of the first portion 21 to pass over the blocking structure.

[0129] Figure 12A A schematic diagram of the coupling mechanism 95 of the vehicle lock assembly 1 according to another embodiment of the present invention is shown. Figures 12B to 12FSide views of the coupling mechanism 95 in different states are shown. It should be noted that... Figures 12A to 12F The coupling mechanism 95 shown can be coupled with Figures 1A to 10 Other parts or components of the illustrated vehicle lock assembly 1 may be combined or modified without exceeding the scope of the invention.

[0130] Figure 12A The drive member 10 of the vehicle lock assembly 1 is shown in a simplified manner. The drive member 10 is configured to rotate about a third axis 83. For example, the vehicle lock assembly 1 includes a fixed base 23 on which a first base shaft 231 is provided, and the drive member 10 is rotatably mounted on the first base shaft 231. However, the drive member 10 may also be configured to rotate about other axes fixed relative to the vehicle lock assembly 1. Figure 12A A first portion 21 of the first mechanism is also shown, which is the drive member 10. Furthermore, depending on the definition and specific construction of the drive member 10, the first portion 21 may also be formed as part of the drive member 10. In the above case, the first portion 21 can be configured to move integrally with the drive member 10. Figure 12A Specifically, the first portion 21 may include a sloping protrusion 14 that protrudes from the surface of the drive member 10 and has two sloping sides and a protruding top 141 located between the two sides. Figure 12A As shown, the protruding top 141 may have an elongated profile; however, the protruding top 141 may also have other shapes.

[0131] Figure 12A A second part 22 of the second mechanism is also shown, which is a separate component from the first part 21. The second part 22 is, for example, fitted onto a second base shaft 232 disposed on the base 23, and is rotatable about the second base shaft 232 within a certain range, defined, for example, by a structure (not shown) of the lock assembly 1. The second part 22 may include a second part body and a sheet-like spring portion 228 deflected relative to the second part body. Specifically, the spring portion 228 extends near the surface of the drive member 10 and extends obliquely away from the drive member 10 relative to the second part body. Therefore, the spring portion 228 is prone to elastic deformation, i.e., warping deformation, in a direction away from the drive member 10. (Reference) Figure 12A The first part 21 and the second part 22 are configured such that when the second part 22 rotates, causing the spring portion 228 to approach the sloped protrusion 14 from one side, the continued rotation of the second part 22 causes the spring portion 228 to contact the sloped side of the sloped protrusion 14. In this embodiment, if the second part 22 continues to rotate when the drive member 10 is not rotating, the spring portion 228 slides relative to the surface of the sloped protrusion 14 and moves to elastically press against the top 141 of the protrusion.

[0132] Figures 12B to 12E The relationship between the first part 21 and the second part 22 coupled to each other is illustrated, which exemplarily shows the first part 21 driving the second part 22 from the unlocked position (see reference). Figure 12B Move to the locked position (refer to) Figure 12E The process of ). In Figure 12B In the view shown, the spring piece 228 is located approximately to the left of the protruding top 141. (Refer to...) Figure 12C Drive component 10 relative to Figure 12B As shown, rotating clockwise, the side of the sloping protrusion 14 pushes the spring piece 228. Because the rotation angle of the second part 22 is limited, and the spring piece 228 can elastically deform in a direction away from the drive member 10, in... Figure 12C In the view shown, the protruding top 141 moves to at least partially contact and press against the spring piece 228. (Refer to...) Figure 12D The drive member 10 can continue to rotate clockwise, and the spring piece 228 passes over the protruding top 141, at least partially restoring the elastic deformation of the spring piece 228. Figures 12D to 12E The drive member 10 rotates counterclockwise, and the sloping side of the sloping protrusion 14 pushes the spring portion 28, causing the second part 22 to rotate clockwise, thereby moving the second part 22 from the unlocked position to the locked position. In a similar manner, the first part 21 can also drive the second part 22 from the locked position to the unlocked position. Thus, the first part 21 and the second part 22 are coupled to each other as shown in the figure.

[0133] Refer to in sequence Figure 12E , Figure 12F and Figure 12B This describes how the second part 22 is driven independently of the first part 21 to decouple the aforementioned relationship between the first part 21 and the second part 22. Figures 12E to 12F The position of the driving component 10 remains unchanged, that is, the position of the first part 21 remains unchanged. On the other hand, from Figures 12E to 12F The second part 22 is independently driven (e.g., from a door handle, mechanical lock, emergency lock, etc., as described above). Since the first part 21 is configured to be driven by a power source, the second part 22 has difficulty pushing the first part 21 to move accordingly (i.e., the drive member 10 is difficult to be driven to rotate by the second part 22). Therefore, in the illustrated configuration, the second part 22 rotates counterclockwise on one hand due to the positional constraint of the sloping protrusion 14, and on the other hand slides along the surface of the sloping protrusion 14 via the spring portion 228 to pass over the top 141 of the protrusion. Figures 12F to 12B If the second part 22 continues to be driven independently, then the second part 22 will rotate counterclockwise on the one hand, and its elastic deformation will at least partially recover on the other hand. Thus, the second part 22 moves independently of the first part 21 from... Figure 12E The locked position shown is moved to Figure 12BThe first part 21 is moved to the unlocked position and remains in the unlocked position. Similarly, the second part 22 can also be driven independently of the first part 21, moving from the unlocked position to the locked position and remaining there. Once the second part 22 has moved to and remained in the new position, if the first part 21 is moved by a power source, the first part 21 and the second part 22 will recouple to each other.

[0134] It should be pointed out that, Figure 12A and Figure 12F The examples shown are merely illustrative embodiments. Figures 12A to 12F As shown, the first portion 21 includes a blocking structure (e.g., a ramp 14) to restrict movement of the second portion 22 relative to the first portion 21, such that the first portion 21 and the second portion 22 are coupled to each other, while when the second portion 22 is driven independently of the first portion 21, the second portion 22 moves to pass over the blocking structure to decouple the first portion 21 and the second portion 22. For example, as Figures 12A to 12F Specifically, the second part 22 is elastically deformable relative to the first part 21, such that when the second part 22 is driven independently of the first part 21, the second part 22 slides along the surface of the first part 21 to pass over the blocking structure.
