[0025]

[0023] The following describes in detail the embodiments of the present application. Examples of the embodiments are illustrated in the accompanying drawings, in which the same or similar reference numerals indicate the same or similar elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application, and should not be understood as limitations on the present application.

[0026] An actuator 100 according to an embodiment of the present application is described below with reference to FIGS.

[0027] 1-14 , an actuator 100 according to an embodiment of the present application includes a housing 1, a driver, an output rotor 3, a first cable 41, and a second cable 42. Among other components, the housing 1 has a cable outlet 112, a driver disposed inside the housing 1, the output rotor 3 configured to be rotated in a forward or reverse direction by the driver, the output rotor 3 having a fitting, a first end of the first cable 41 and a first end of the second cable 42 fitted in the fitting, and a second end of the first cable 41 and a second end of the second cable 42 extending out of the outer housing 1 through the cable outlet 112, the output rotor 3 configured to rotate in a forward direction to drive the first cable 41 via the fitting, and the output rotor 3 configured to rotate in a reverse direction to drive the second cable 42 via the fitting.

[0028] Therefore, the output rotor 3 can be driven by the driver to rotate in a forward or reverse direction, so that one of the first cable 41 and the second cable 42 is moved and the other cable remains stable, thereby achieving various functions, which helps to reduce the number of components, reduce costs, and simplify the structure of the actuator 100, and realizes a compact design of the actuator 100.

[0029] 1 to 3 , an installation space may be formed inside the housing 1, and the driver, output rotor 3, first cable 41, and second cable 42 may all be installed within the installation space of the housing 1, thereby allowing the housing 1 to provide shielding protection for the remaining components of the actuator 100 and improve the stability of the actuator 100. A first central shaft 113 may be provided within the installation space, and a first rotation hole 36 may be formed on the output rotor 3, and the first central shaft 113 may be inserted into the first rotation hole 36 so that the output rotor 3 is rotatably installed within the installation space of the housing 1, and the output end of the driver is connected to the output rotor 3 in a power-transmitting manner so that the driver can rotate the output rotor 3 in a forward or reverse direction.

[0030] It should be noted that the forward rotation may be set as clockwise rotation and the reverse rotation may be set as counterclockwise rotation, or the reverse rotation may be set as clockwise rotation and the forward rotation may be set as counterclockwise rotation, and the present application is not limited thereto. Of course, in the embodiment shown in Figure 3, the forward rotation is clockwise rotation and the reverse rotation is counterclockwise rotation, and no further details are given.

[0031] 2 to 4, the output rotor 3 may have a fitting portion, and a first end of a first cable 41 may be movably mounted on the fitting portion, and a first end of a second cable 42 may be movably mounted on the fitting portion. Two guide seats 13 spaced apart in the left-right direction and protruding outward in FIG. 1 are provided on the outer peripheral wall of the housing 1. The housing 1 may form cable outlets 112 at the two guide seats 13, respectively. The cable outlets 112 are used to connect the installation space to the outside of the housing 1. The second end of the first cable 41 may pass through the cable outlet 112 on the left side in FIG. 1 to extend outside the housing 1 and be connected to a corresponding functional component. The second end of the second cable 42 may pass through the cable outlet 112 on the right side in FIG. 1 to extend outside the housing 1 and be connected to a corresponding functional component.

[0032] When the driver rotates the output rotor 3 in a forward direction, the mating portion can facilitate movement of the first end of the first cable 41 to cause movement of the second end of the first cable 41 so as to activate a corresponding functional component, and the mating portion can move relative to the second cable 42 to hold the second cable 42 stationary, while when the driver rotates the output rotor 3 in a reverse direction, the mating portion can facilitate movement of the first end of the second cable 42 to cause movement of the second end of the second cable 42 to activate a corresponding functional component, and the mating portion can move relative to the first cable 41 to hold the first cable 41 stationary. Thus, the first cable 41 and the second cable 42 can be selectively driven to achieve various functions.

[0033] Optionally, a sealing sleeve 14 may be fitted to the outside of the guide seat 13, and the sealing sleeve 14 has a cable exit hole corresponding to the cable exit 112, and the first cable 41 and the second cable 42 can be passed through the cable exit 112 and the cable exit hole sequentially to extend to the outside of the housing 1, and the sealing sleeve 14 is used to seal the cable exit 112 to prevent foreign objects from entering the installation space.

[0034] According to the actuator 100 of the present application, the driver can rotate the output rotor 3 in a forward direction to promote movement of the first cable 41 while keeping the second cable 42 stationary, and the driver can rotate the output rotor 3 in a reverse direction to promote movement of the second cable 42 while keeping the first cable 41 stationary, thereby achieving various functions, and the structure of the actuator 100 is simple with fewer components, reducing costs and facilitating a compact design of the actuator 100.

[0035] In some embodiments of the present application, the output rotor 3 is provided with a groove 31 extending along its rotational direction, the mating portion is defined by the groove 31, the first end of the first cable 41 is inserted into the groove 31 and contacts the first end face 311 of the groove 31, and the first end of the second cable 42 is inserted into the groove 31 and contacts the second end face 312 of the groove 31.

[0036] For example, referring to FIG. 4 , the output rotor 3 may be configured as a disk, with a first rotation hole 36 that penetrates vertically at the center of the output rotor 3, and an arc-shaped groove 31 that is provided on the upper side of the output rotor 3 and surrounds the first rotation hole 36. The central axis of the groove 31 is aligned with the central axis of the first rotation hole 36, and the counterclockwise end face of the groove 31 may be set as a first end face 311, and the clockwise end face of the groove 31 may be set as a second end face 312. Referring to FIG. 2 , both the first end of the first cable 41 and the first end of the second cable 42 have a limit column 43, which is cylindrical. The diameter of the limit column 43 is equal to or less than the width of the groove 31, and the limit column 43 is used to be movably inserted into the groove 31.

[0037] Here, the limit column 43 of the first cable 41 can be inserted into the groove 31 so that the outer wall of the limit column 43 of the first cable 41 contacts the first end face 311 of the groove 31, and the limit column 43 of the second cable 42 can be inserted into the groove 31 so that the limit column 43 of the second cable 42 contacts the second end face 312 of the groove 31. In this manner, when the driver rotates the output rotor 3 in the forward direction, the first end face 311 exerts a force on the limit column 43 of the first cable 41, pulling and moving the second end of the first cable 41, and the limit column 43 of the second cable 42 is able to move along the groove 31 relative to the output rotor 3 so that the second end of the second cable 42 remains stationary; when the driver rotates the output rotor 3 in the reverse direction, the second end face 312 exerts a force on the limit column 43 of the second cable 42, pulling and moving the second end of the second cable 42, and the limit column 43 of the first cable 41 is able to move along the groove 31 relative to the output rotor 3 so that the second end of the first cable 41 remains stationary. Thus, the first cable 41 and the second cable 42 can be selectively driven.

[0038] Through the above arrangement, the structure of the output rotor 3 is simplified, which leads to a reduction in the processing costs of the output rotor 3, and the movement of the output rotor 3 is stable and reliable, which leads to an improvement in the reliability of the actuator 100.

[0039] In some embodiments of the present application, the alignment portion may include two alignment grooves, each formed to extend along the rotational direction of the output rotor 3, and the first end of the first cable 41 and the first end of the second cable 42 are inserted into the two alignment grooves in a one-to-one correspondence, respectively, to realize selective driving of the first cable 41 and the second cable 42.

[0040] In some embodiments of the present application, cable spaces 32 are arranged on both sides of the mating portion in the rotational direction of the output rotor 3, through holes 33 are provided in the side walls of the mating portion, the through holes 33 extend along the rotational direction of the output rotor 3, each of the cable spaces 32 is connected to the mating portion through the through holes 33, and the first cable 41 and the second cable 42 extend outside the output rotor 3 through the through holes 33 and the cable spaces 32.

[0041] 3-4, for example, cable spaces 32 may be provided on both sides of the groove 31 in the circumferential direction of the output rotor 3, and the cable spaces 32 are provided on the outer peripheral wall of the output rotor 3 and open outward. A through hole 33 for wiring is provided on the side wall of the groove 31 far from the first rotation hole 36, and the through hole 33 is used to connect the groove 31 to the radially outer side of the output rotor 3. The through hole 33 extends along the circumferential direction of the output rotor 3, and the width dimension of the through hole 33 is equal to or less than the width dimension of the cable space 32. One end of the through hole 33 is used to communicate with the corresponding cable space 32 so that the groove 31 is connected to each of the two cable spaces 32 through the corresponding through hole 33. 3 , after the limit columns 43 of the first cable 41 and the second cable 42 are inserted into the groove 31, the first cable 41 and the second cable 42 can extend through the through hole 33 into the cable space 32, be arranged along the cable space 32, and extend out of the cable space 32 directly toward the cable outlet 112. Therefore, by providing the cable space 32, the first cable 41 and the second cable 42 can avoid other components so as to avoid interference with the movement of the first cable 41 and the second cable 42, and the overall bending of the first cable 41 and the second cable 42 is relatively small, which leads to improved stability of the movement of the first cable 41 and the second cable 42.

[0042] For example, referring to FIG. 4, a notch 34 may be provided on the upper side of the output rotor 3 at a position corresponding to the through hole 33 for wiring, and the notch 34 is used to connect the through hole 33 with the outside, and the first cable 41 and the second cable 42 can be inserted into or removed from the through hole 33 through the notch 34, thereby making the assembly and disassembly process of the first cable 41 and the second cable 42 simple, which leads to reducing the difficulty of maintenance.

[0043] In some embodiments of the present application, the housing 1 is provided with a cable routing slot 111 on the inside, and the first cable 41 and / or the second cable 42 pass through the cable routing slot 111 and then extend toward the cable outlet 112. In this way, by providing the cable routing slot 111, the routing direction of the first cable 41 and / or the second cable 42 can be guided, and the risk of the first cable 41 and / or the second cable 42 getting tangled can be reduced.

[0044] 3 and 6 , for example, a baffle may be provided in the installation space of the housing 1, the baffle being used to separate the cable outlet 112 from the output rotor 3, and a cable routing slot 111 being provided on the baffle, the cable routing slot 111 being used to connect the output rotor 3 and the cable outlet 112. In this way, after the first cable 41 and the second cable 42 extend out of the output rotor 3, they can pass through the cable routing slot 111 and extend from the cable outlet 112 to the outside of the housing 1.

[0045] Through the above arrangement, external foreign matter coming in from the cable outlet 112 can be prevented from flowing directly to the output rotor 3, which reduces the accumulation of dust on the output rotor 3, helps reduce the maintenance frequency, and improves the utility of the output rotor 3.

[0046] In some embodiments of the present application, the housing 1 includes a first housing 11 and a second housing 12, which cooperate to define an installation space, and the driver and output rotor 3 are installed within the installation space.

[0047] 2-3, the first housing 11 may be configured as an upward-facing box-like structure, the second housing 12 may be designed with a corresponding shape with respect to the open end of the first housing 11, the second housing 12 may be detachably installed on the upper side of the first housing 11 to seal the open end of the first housing 11, an installation space may be defined between the first housing 11 and the second housing 12, and the driver and output rotor 3 may be installed on the first housing 11, both of which may be disposed within the installation space. In this manner, the housing 11 may improve the stability of the actuator 100 by protecting the driver and output rotor 3, and when the driver and output rotor 3 fail, the second housing 12 may be separated from the first housing 11 to expose the driver and output rotor 3 to the outside, which may facilitate maintenance and reduce the difficulty of maintenance.

[0048] In some embodiments of the present application, the first housing 11 is provided with a cable routing guide slot 111, one side of which is open toward the second housing 12, and the second housing 12 is provided with a stop rib 121, which is arranged on the open side of the cable routing guide slot 111.

[0049] 5-6 , a baffle may be provided on the underside of the first housing 11, the baffle being arranged to extend upward, and two upwardly extending limit plates 116 being spaced apart above the baffle, an upwardly opening cable routing slot 111 being defined between the two limit plates 116, and a downwardly protruding stop rib 121 being provided on the underside of the second housing 12 corresponding to the cable routing slot 111, with two side surfaces of the stop rib 121 being used to support the upper ends of the two limit plates 116 and the stop rib 121 being used to close the open end of the cable routing slot 111. In this way, the first cable 41 and the second cable 42 can be prevented from being disengaged from the cable routing slot 111 during movement, which helps improve the reliability of the first cable 41 and the second cable 42 and improves the stability of the actuator 100.

[0050] In some embodiments of the present application, referring to FIG. 2 , the actuator 100 according to an embodiment of the present application further includes a matching gear set 5, which includes an input gear 51 and an output gear 52, and the driver rotates the input gear 51, and the output gear 52 is configured to engage with the output rotor 3 to rotate the output rotor 3.

[0051] For example, the matching gear set 5 may be installed in the installation space, and the matching gear set 5 includes an input gear 51 and an output gear 52, the input gear 51 is used to mesh with the output end of the driver, and the driver can rotate the input gear 51 to rotate the output gear 52, and the output gear 52 is power-meshed with the output rotor 3 so that the output gear 52 can rotate the output rotor 3 to move the first cable 41 or the second cable 42 by realizing forward or reverse rotation of the output rotor 3.

[0052] For example, referring to Figures 2-3 and 5, a second central shaft 114 and a third central shaft 115 may be spaced apart on the first housing 11, with the second central shaft 114 and the third central shaft 115 both extending vertically, and an input gear 51 rotatably fitted on the second central shaft 114, the input gear 51 having a first gear segment 511 and a second gear segment 512, with the first gear segment 511 being used to mesh with the output end of the driver and the second gear segment 512 being positioned below the first gear segment 511. The output gear 52 is rotatably fitted on the third central shaft 115, and has a third gear segment 521 and a fourth gear segment 522, the third gear segment 521 being disposed below the fourth gear segment 522 and used to mesh with the second gear segment 512 of the input gear 51, and the first gear segment 511 and the fourth gear segment 522 being horizontally spaced apart so that the input gear 51 can rotate the output gear 52 around the third central shaft 115. Now, referring to FIG. 4 , an outer lower portion of the output rotor 3 has an outer gear portion 35, which is used to mesh with the fourth gear segment 522 so that the output gear 52 can rotate the output rotor 3.

[0053] Through the above arrangement, the driver can rotate the output rotor 3 at the required speed, the rotation process is smooth and reliable, and the matching gear set 5 has a small vertical occupied space, which helps improve the rationality of the installation space layout and reduce the vertical size of the actuator 100.

[0054] In some embodiments of the present application, the driver is a motor 2, the rotation axis of the motor shaft 21 of the motor 2 is at an angle with the central axis of the input gear 51, and the motor shaft 21 has an external thread that engages with the input gear 51.

[0055] 2-3, the driver may be configured as a motor 2, which is generally arranged to extend horizontally and has a motor shaft 21, with the central axis of an input gear 51 extending vertically such that the rotation axis of the motor shaft 21 forms a 90-degree angle with the central axis of the input gear 51. The motor shaft 21 has an external thread on the outside, which is used to mesh with a first gear segment 511 of the input gear 51 so that the motor shaft 21 can rotate the input gear 51, which in turn rotates the output rotor 3 through the output gear 52.

[0056] It can be seen that by setting the rotation axis of the motor shaft 21 at a certain angle with the central axis of the input gear 51, it helps to reduce the occupation of installation space, improves the compactness and rationality of the layout, and helps to reduce the overall volume of the actuator 100.

[0057] In some other embodiments of the present application, the driver may be a motor, and the motor shaft is directly coupled to the output rotor 3 to rotate the output rotor 3 in a forward or reverse direction, so that the coupling method is simple.

[0058] The present application also proposes a door lock assembly 200.

[0059] As shown in FIGS. 7 and 8 , a door lock assembly 200 according to an embodiment of the present application includes a mounting plate 201, a locking arm assembly 202 that is rotatable and mounted on the mounting plate 201, a locking hook 203 that is rotatable and mounted on the mounting plate 201 and is locked or unlocked by the locking arm assembly 202, a locking hook 203, an ice-breaking rocker arm 204 that is mounted on the locking hook 203 and rotates the locking hook 203, and a retraction assembly 205 that is rotatable and mounted on the mounting plate 201. a retraction assembly (205); and an actuator (100) according to any one of the above embodiments, wherein the second end of the second cable (42) is connected to the icebreaker rocker arm (204) and the second end of the first cable (41) is connected to the retraction assembly (205), wherein when the output rotor (3) rotates in a forward direction, the first cable (41) rotates the retraction assembly (205) and pushes and rotates the locking hook (203) to be locked by the locking arm assembly (202), and when the output rotor (3) rotates in a reverse direction, the second cable (42) rotates and rotates the icebreaker rocker arm (204) to rotate the locking hook (203) away from the locking arm assembly (202).

[0060] Therefore, locking of the vehicle door may be achieved by using a driver to rotate the output rotor 3 in a forward direction so that the first cable 41 causes the lock hook 203 to lock with the locking arm assembly 202, and unlocking of the vehicle door may be achieved by using a driver to rotate the output rotor 3 in a reverse direction so that the second cable 42 causes the ice breaking rocker arm 204 to drive the lock hook 203 to disengage from the locking arm assembly 202. The structure of the door lock assembly 200 is simple with fewer parts, which helps reduce costs and the working process is stable and reliable.

[0061] For example, referring to FIGS. 7-8 , a plurality of spaced apart connecting rotation holes may be provided on the mounting plate 201, and the locking arm assembly 202 may have matching holes, where a rotation pin is adapted to pass through the matching holes of the locking arm assembly 202 and the connecting rotation hole of the mounting plate 201 to rotatably mount the locking arm assembly 202 on the left region of the mounting plate 201. The locking hook 203 may have corresponding matching holes, where a rotation pin is adapted to pass through the matching holes of the locking hook 203 and the connecting rotation hole of the mounting plate 201 to rotatably mount the locking hook 203 in the central region of the mounting plate 201. The locking hook 203 has an unlocked position and a locked position, and the locking hook 203 may be rotated clockwise to switch from the unlocked position to the locked position. When the locking hook 203 is in the unlocked position, the vehicle door is unlocked, and when the locking hook 203 is in the locked position, the vehicle door is locked. The left side of the locking hook 203 is used to cooperate with the locking arm assembly 202, and the locking arm assembly 202 is used to prevent the locking hook 203 from rotating counterclockwise so that the locking hook 203 is in the locked position.

[0062] Here, the actuator 100 is spaced to the right of the mounting plate 201 (the right here merely indicates the approximate location of the actuator 100 and is not limited to this arrangement), and both the first cable 41 and the second cable 42 of the actuator 100 are configured with a flexible structure, and the first cable 41 and the second cable 42 extend leftward toward the mounting plate 201. An icebreaker rocker arm 204 is provided on the lock hook 203, and the icebreaker rocker arm 204 is connected to a lower region of the lock hook 203, and the second end of the second cable 42 is connected to the end of the icebreaker rocker arm 204 farther from the lock hook 203, and the second cable 42 can rotate the lock hook 203 counterclockwise through the icebreaker rocker arm 204 to move the lock hook 203 to the unlocked position.

[0063] At the same time, the retraction assembly 205 includes a first retraction structure 205a and a second retraction structure 205b, the first retraction structure 205a has an alignment hole, and a rotation pin is adapted to pass through the alignment hole of the first retraction structure 205a and the connecting rotation hole of the mounting plate 201 to rotatably install the first retraction structure 205a on the upper right side of the mounting plate 201. The left side of the first retraction structure 205a is rotatably connected to the second retraction structure 205b, which is used to press down the right side of the locking hook 203, and the underside of the first retraction structure 205a is connected to the second end of the first cable 41. The first cable 41 can rotate the first retraction structure 205a counterclockwise so that the second retraction structure 205b can rotate the locking hook 203 clockwise, thereby rotating the locking hook 203 to the locked position.

[0064] 12-13, in a specific operation process, when the vehicle door is locked and the external temperature is too low and the lock hook 203 is frozen, when the user controls the vehicle door to be unlocked, the reverse force of the unlocking process is insufficient, and the lock hook 203 will remain in the locked position, preventing the vehicle door from being opened. At this point, the driver can drive the output rotor 3 in the reverse direction, and the cooperating parts can pull the second cable 42, and the second end of the second cable 42 can pull the ice breaker rocker arm 204 and rotate it counterclockwise around the rotating pin. The ice breaker rocker arm 204 rotates the lock hook 203 counterclockwise and away from the locking arm assembly 202, switching it to the unlocked position, thereby achieving the ice breaker lock release of the vehicle door. 9 to 11, when the locking hook 203 is not in the closed position, the driver can rotate the output rotor 3 in a forward direction, and the cooperating parts can pull the first cable 41, and the second end of the first cable 41 can pull the retraction assembly 205 to rotate it counterclockwise around the rotation pin, and the second retraction structure 205b can apply a downward force to the right side of the locking hook 203 so that the locking hook 203 can rotate clockwise to the locked position, thereby achieving locking of the vehicle door.

[0065] Through the above-mentioned setup, the output rotor 3 may be rotated in a forward direction by a driver so that the first cable 41 locks the lock hook 203 and the locking arm assembly 202, thereby realizing the locking of the vehicle door. Furthermore, the output rotor 3 may be rotated in a reverse direction by a driver so that the second cable 42 drives the ice-breaking rocker arm 204 to move the lock hook 203 away from the locking arm assembly 202, thereby realizing the de-icing unlocking of the vehicle door. The working process of the door lock assembly 200 is stable and reliable, and the structure of the door lock assembly 200 is simple with fewer parts, which is beneficial to reducing costs.

[0066] In some embodiments of the present application, the locking hook 203 includes a first mating portion 203a and a second mating portion 203b, the locking arm assembly 202 includes a first locking portion 202a and a second locking portion 202b, and the door lock assembly 200 includes a half-locked state and a fully-locked state. In the half-locked state, the first mating portion 203a engages with the first locking portion 202a, and in the fully-locked state, the second mating portion 203b engages with the second locking portion 202b.

[0067] 8-11, the locking hook 203 may have a first mating portion 203a and a second mating portion 203b arranged sequentially in a counterclockwise direction on the outside of the locking hook 203, with the first mating portion 203a arranged on the side of the second mating portion 203b that is farther from the mounting plate 201. The locking arm assembly 202 has a first locking portion 202a and a second locking portion 202b, where the first locking portion 202a is arranged on the side of the second locking portion 202b that is farther from the mounting plate 201 and faces the first mating portion 203a.

[0068] The door lock assembly 200 has an unlocked state, a half-locked state, and a fully locked state, that is, the door lock can be set to have an unlocked position, a half-locked position, and a locked position. As shown in Fig. 9, when the door lock assembly 200 is in the unlocked state, the lock hook 203 is in the unlocked position, and the first mating portion 203a and the second mating portion 203b are spaced apart from the locking arm assembly 202, so that the automobile door can move freely relative to the body. As shown in FIG. 10 , when the door lock assembly 200 is in a half-locked state, the lock hook 203 is in a half-locked position, and the first fitting portion 203a is engaged with the first locking portion 202a, so that the locking arm assembly 202 can prevent the lock hook 203 from rotating clockwise to the unlocked position to achieve self-unlocking, and the user can move the lock hook 203 to the unlocked position through the inside or outside handle of the automobile door to unlock the door. As shown in FIG. 11 , when the door lock assembly 200 is in a fully locked state, the lock hook 203 is in a locked position, and the second fitting portion 203b of the lock hook 203 engages with the first locking portion 202a of the locking arm assembly 202, so that the locking arm assembly 202 can prevent the lock hook 203 from rotating clockwise to the unlocked position to achieve self-unlocking, and the user cannot rotate the lock hook 203 through the handle inside or outside the automobile door, so that the automobile door is fully locked.

[0069] It can be appreciated that by configuring the door lock assembly 200 to have multiple different states, the automobile door can have a variety of states that meet the actual needs of the user, which is beneficial to increasing user satisfaction.

[0070] In some embodiments of the present application, the retraction assembly 205 rotates to rotate the lock hook 203, thereby switching the door lock assembly 200 from a half-locked state to a fully-locked state. For example, referring to FIGS. 10-11 , when the door lock assembly 200 is in a half-locked state, the lock hook 203 is in a half-locked position. At this time, the output rotor 3 may be rotated forward, the mating portion pulls the first cable 41, and the second end of the first cable 41 can pull the first retraction structure 205a and rotate it counterclockwise around the pivot pin. The second retraction structure 205b applies a downward force to the right side of the lock hook 203, causing it to rotate clockwise to the locked position. The second fitting portion 203b of the lock hook 203 engages with the second locking portion 202b of the locking arm assembly 202 to switch the door lock assembly 200 to a fully locked state. In this way, the locking process of the automobile door is simplified, which is beneficial to improving the reliability of the automobile door lock and enhancing the safety of passengers.

[0071] The present application also discloses a vehicle 300 .

In the vehicle 300, the driver can rotate the output rotor 3 in a forward direction so that the first cable 41 engages the lock hook 203 with the locking arm assembly 202, thereby locking the vehicle door. Furthermore, the driver can rotate the output rotor 3 in a reverse direction so that the second cable 42 drives the ice-breaking rocker arm 204 to move the lock hook 203 away from the locking arm assembly 202, thereby unlocking the ice-breaking lock of the vehicle door. The working process of the door lock assembly 200 is stable and reliable, and the structure of the door lock assembly 200 is simple with fewer components, which is beneficial for reducing costs and therefore improving the overall performance of the vehicle 300.
