The actuator 100 according to the embodiment of the present application is described below with reference to FIGS. 1-14.

Referring to FIGS. 1-14, the actuator 100 according to the 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 them, the housing 1 having a cable outlet 112; the driver being disposed inside the housing 1; the output rotor 3 being configured to be driven to rotate forward or backward by the driver, the output rotor 3 having a fitting part; a first end of the first cable 41 and a first end of the second cable 42 fitting to the fitting part, 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 is configured to rotate forward to drive the first cable 41 through the fitting part, and the output rotor 3 is configured to rotate backward to drive the second cable 42 through the fitting part.

Therefore, the output rotor 3 can be driven by the driver to rotate forward or backward, so that one of the first cable 41 and the second cable 42 is moved and the other one remain stable, thereby achieving different functions, which is helpful to reduce the number of components, reduce the cost, simplify the structure of the actuator 100, and minimize the size of the actuator 100.

For example, referring to FIGS. 1-3, an installation space can be formed inside the housing 1, and the driver, the output rotor 3, the first cable 41 and the second cable 42 are all installed in the installation space of the housing 1, so that the housing 1 can provide shielding protection for the remaining parts of the actuator 100, to improve the stability of the actuator 100. A first central shaft 113 can be provided in the installation space, and a first rotation hole 36 can be formed on the output rotor 3, and the first central shaft 113 can be inserted into the first rotation hole 36, so that the output rotor 3 is rotatably installed in the installation space of the housing 1, and the output end of the driver is connected to the output rotor 3 in a power transmission manner, so that the driver can drive the output rotor 3 to rotate forward or backward.

It needs to be noted that the forward rotation can be set as clockwise rotation, and the backward rotation can be set as counterclockwise rotation. Or the backward rotation can be set as clockwise rotation, and the forward rotation can be set as counterclockwise rotation. The present application does not limit this. Of course, in the embodiment shown in FIG. 3, the forward rotation is clockwise rotation, and the backward rotation is counterclockwise rotation.

For example, referring to FIGS. 2-4, the output rotor 3 can have a fitting part, the first end of the first cable 41 can be movably installed on the fitting part, and the first end of the second cable 42 can be movably installed on the fitting part. Two guide seats 13 that are spaced apart in the left-right direction in FIG. 1 and protrude outward are provided on the outer peripheral wall of the housing 1. The housing 1 can form cable outlet 112 respectively at the two guide seats 13, the cable outlet 112 are used to connect the installation space with the outside of the housing 1. The second end of the first cable 41 can pass through the cable outlet 112 on the left side in FIG. 1 and extend to the outside of the housing 1, and be connected to the corresponding functional component. The second end of the second cable 42 can pass through the cable outlet 112 on the right side in FIG. 1 and extend to the outside of the housing 1, and be connected to the corresponding functional component.

When the driver drives the output rotor 3 to rotate forward, the fitting part can drive the first end of the first cable 41 to move, to pull the second end of the first cable 41 to move, so as to drive the corresponding functional component to work, and the fitting part can move relative to the second cable 42 to keep the second cable 42 stationary. When the driver drives the output rotor 3 to rotate backward, the fitting part can drive the first end of the second cable 42 to move, to pull the second end of the second cable 42 to move, so as to drive the corresponding functional component to work, and the fitting part can move relative to the first cable 41 to keep the first cable 41 stationary. Thereby, the first cable 41 and the second cable 42 can be selectively driven to achieve different functions.

In an embodiment, a sealing sleeve 14 can be fitted outside the guide seat 13, and has a cable outlet hole corresponding to the cable outlet 112. The first cable 41 and the second cable 42 can be sequentially passed through the cable outlet 112 and the cable outlet hole to extend to the outside of the housing 1. The sealing sleeve 14 is used to seal the cable outlet 112, in order to prevent foreign matter from entering the installation space.

According to the embodiments of the present application, the driver can drive the output rotor 3 to rotate forward, so as to drive the first cable 41 to move while keeping the second cable 42 stationary, and can drive the output rotor 3 to rotate backward, so as to drive the second cable 42 to move while keeping the first cable 41 stationary, thereby achieving different functions, simplifying the structure of the actuator 100 with fewer components, reducing the cost, and minimizing the size of the actuator 100.

In some embodiments of the present application, the output rotor 3 is provided with a groove 31 extending along its rotation direction, the fitting part is defined by the groove 31, the first end of the first cable 41 is inserted into the groove 31 and in contact with the first end surface 311 of the groove 31, the first end of the second cable 42 is inserted into the groove 31 and in contact with the second end surface 312 of the groove 31.

For example, referring to FIG. 4, the output rotor 3 can be constructed as a disk, a first rotation hole 36 penetrating vertically is provided at the center position of the output rotor 3, and an arc-shaped groove 31 is provided on the upper side of the output rotor 3 surrounding the first rotation hole 36. The central axis of the groove 31 is aligned with the central axis of the first rotation hole 36, the end face of the groove 31 in the counterclockwise direction can be set as the first end surface 311, and the end face of the groove 31 in the clockwise direction can be set as the second end surface 312. Referring to FIG. 2, the first end of the first cable 41 and the first end of the second cable 42 have a limit column 43, and the limit column 43 is a cylindrical body. 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 movably inserted into the groove 31.

The limit column 43 of the first cable 41 can be inserted into the groove 31, so that the outer peripheral wall of the limit column 43 of the first cable 41 is in contact with the first end surface 311 of the groove 31. 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 is in contact with the second end surface 312 of the groove 31. In this way, when the driver drives the output rotor 3 to rotate forward, the first end surface 311 can exert a force on the limit column 43 of the first cable 41 to pull the second end of the first cable 41 to move, and the limit column 43 of the second cable 42 can move relative to the output rotor 3 along the groove 31, so that the second end of the second cable 42 remains stationary. When the driver drives the output rotor 3 to rotate backward, the second end surface 312 can exert a force on the limit column 43 of the second cable 42 to pull the second end of the second cable 42 to move, and the limit column 43 of the first cable 41 can move relative to the output rotor 3 along the groove 31, so that the second end of the first cable 41 remains stationary. Therefore, the first cable 41 and the second cable 42 can be selectively driven.

Through the above configuration, the structure of the output rotor 3 is simplified, which is conducive to reducing the processing cost of the output rotor 3, and the movement of the output rotor 3 is stable and reliable, which is conducive to improving the reliability of the actuator 100.

In some embodiments of the present application, the matching part may include two matching grooves, each matching groove is formed to extend along the rotation direction of the output rotor 3, the first end of the first cable 41 and the first end of the second cable 42 are respectively inserted into the two matching grooves in a one-to-one correspondence, in order to realize the selective driving of the first cable 41 and the second cable 42.

In some embodiments of the present application, in the rotation direction of the output rotor 3, cable spaces 32 are arranged on both sides of the fitting part. A side wall of the fitting part is provided with a through-hole 33, and the through-hole 33 extends along the rotation direction of the output rotor 3. Each of the cable spaces 32 is connected with the fitting part through the through-hole 33, and the first cable 41 and the second cable 42 extend out of the output rotor 3 through the through-hole 33 and the cable spaces 32.

For example, referring to FIGS. 3-4, the cable spaces 32 can be respectively 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 are adapted to open outward. A through-hole 33 for wiring is provided on the side wall of the groove 31 far away from the first rotation hole 36, the through-hole 33 is used to connect the groove 31 with the radial outer side of the output rotor 3, the through-hole 33 extends along the circumferential direction of the output rotor 3, the width dimension of the through-hole 33 is not greater 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 can be connected with the two cable spaces 32 through the corresponding through-holes 33 respectively. In this way, referring to FIG. 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 to the cable space 32 through the through-hole 33 and be arranged along the cable space 32, and extend out of the cable space 32 and directly towards the cable outlet 112. Thus, by providing the cable spaces 32, the first cable 41 and the second cable 42 can avoid other components, so as to avoid interference of other components 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 is conducive to improving the stability of the movement of the first cable 41 and the second cable 42.

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

In some embodiments of the present application, the housing 1 is provided with a cable routing slot 111 inside, the first cable 41 and/or the second cable 42 passes through the cable routing slot 111 and then extend towards 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 being entangled can be reduced.

For example, referring to FIGS. 3 and 6, a baffle can be provided in the installation space of the housing 1. The baffle is used to separate the cable outlet 112 from the output rotor 3, and a cable routing slot 111 is provided on the baffle, the cable routing slot 111 is used to connect the output rotor 3 with 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 to the outside of the housing 1 from the cable outlet 112.

Through the above configuration, the external foreign matter can be prevented from entering through the cable outlet 112 and directly flowing to the output rotor 3, which reduces the accumulation of dust on the output rotor 3, reduces the maintenance frequency, and improves the practicality of the output rotor 3.

In some embodiments of the present application, the housing 1 includes a first housing 11 and a second housing 12, the first housing 11 and the second housing 12 are configured to define an installation space, and the driver and the output rotor 3 are installed in the installation space.

In this way, the housing 1 can protect the driver and the output rotor 3, thereby improving the stability of the actuator 100. When the driver and the output rotor 3 fail, the second housing 12 can be detached from the first housing 11 to expose the driver and the output rotor 3 outward, which is conducive to maintenance and helps reduce the difficulty of maintenance.

In some embodiments of the present application, the first housing 11 is provided with the cable routing slot 111, one side (e.g., a first side) of the cable routing slot 111 is open towards the second housing 12, the second housing 12 is provided with a stop rib 121, and the stop rib 121 is located on the open side (e.g., the first side) of the cable routing slot 111.

For example, referring to FIGS. 5-6, a baffle can be provided on the upper side of the first housing 11. The baffle is arranged to extend upward, and two upward-extending limiting plates 116 are spaced apart on the upper side of the baffle. The cable routing slot 111 that is open upward is defined between the two limiting plates 116, a downward protruding stop rib 121 is provided on the lower side of the second housing 12 corresponding to the cable routing slot 111, the two sides of the stop rib 121 are used to support the upper ends of the two limiting plates 116, and the stop rib 121 is used to close the open side of the cable routing slot 111. In this way, the first cable 41 and the second cable 42 can be prevented from disengaging from the cable routing slot 111 during the movement, which improves the reliability of the first cable 41 and the second cable 42, and improves the stability of the actuator 100.

In some embodiments of the present application, referring to FIG. 2, the actuator 100 includes a match gear set 5. The match gear set 5 includes an input gear 51 and an output gear 52, the driver drives the input gear 51 to rotate, and the output gear 52 is configured to engage with the output rotor 3 to drive the output rotor 3 to rotate.

The match 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, the driver can drive the input gear 51 to rotate. The output gear 52 is meshed with the output rotor 3, so that the output gear 52 can drive the output rotor 3 to rotate, so as to realize the forward or backward rotation of the output rotor 3, thereby driving the first cable 41 or the second cable 42 to move.

For example, referring to FIGS. 2-3 and FIG. 5, a second central shaft 114 and a third central shaft 115 can be spaced apart on the first housing 11. The second central shaft 114 and the third central shaft 115 extend vertically, and the input gear 51 is rotatably fitted on the second central shaft 114. The input gear 51 has a first gear segment 511 and a second gear segment 512, the first gear segment 511 is used to mesh with the output end of the driver, and the second gear segment 512 is located below the first gear segment 511. The output gear 52 is rotatably fitted on the third central shaft 115. The output gear 52 has a third gear segment 521 and a fourth gear segment 522. The third gear segment 521 is located below the fourth gear segment 522, the third gear segment 521 is 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 are spaced apart in the horizontal direction, so that the input gear 51 can drive the output gear 52 to rotate around the third central shaft 115. Referring to FIG. 4, the lower part of the outer side of the output rotor 3 has an outer gear part 35. The outer gear part 35 is used to mesh with the fourth gear segment 522, so that the output gear 52 can drive the output rotor 3 to rotate.

Through the above configuration, the driver can drive the output rotor 3 to rotate at the required speed, and the rotation process is smooth and reliable.

The motor 2 has a motor shaft 21, the center axis line of the input gear 51 is arranged to extend vertically, so that the rotation axis of the motor shaft 21 has a 90-degree angle with respect to the center axis line of the input gear 51. The motor shaft 21 has an external thread on the outside. The external threads are used to mesh with the first gear segment 511 of the input gear 51, so that the motor shaft 21 can drive the input gear 51 to rotate, and then through the output gear 52 to drive the output rotor 3 to rotate.

It can be understood that, setting the rotation axis of the motor shaft 21 is at an angle with respect to the center axis line of the input gear 51, reduces the occupation of the installation space, improves the compactness and rationality of the layout, and reduces the overall volume of the actuator 100.

In some embodiments of the present application, the driver can be a motor, and the motor shaft is directly coupled with the output rotor 3 to drive the output rotor 3 to rotate forward or backward, so that the coupling manner is simple.

The structure of the door lock assembly 200 is simple with fewer parts, which reduces the cost, and the working process is stable and reliable.

For example, referring to FIGS. 7-8, multiple spaced-apart connection rotation holes can be provided on the mounting plate 201, and the locking arm assembly 202 has matching holes. The rotation pin is suitable for passing through the matching holes of the locking arm assembly 202 and the connection rotation holes of the mounting plate 201, to rotatably install the locking arm assembly 202 on the left side area of the mounting plate 201. The lock hook 203 has corresponding matching holes, and the rotation pin is suitable for passing through the matching holes of the lock hook 203 and the connection rotation holes of the mounting plate 201, to rotatably install the lock hook 203 in the central area of the mounting plate 201. The lock hook 203 has an unlocked position and a locked position, and the lock hook 203 can rotate clockwise to switch from the unlocked position to the locked position. When the lock hook 203 is in the unlocked position, the vehicle door is unlocked, and when the lock hook 203 is in the locked position, the vehicle door is locked. The left side of the lock hook 203 is used to engage with the locking arm assembly 202, and the locking arm assembly 202 is used to block the counterclockwise rotation of the lock hook 203, so that the lock hook 203 is in the locked position.

The actuator 100 is disposed on the right side of the mounting plate 201 (the right side here indicates the approximate position of the actuator 100, and is not limited to this configuration). The first cable 41 and the second cable 42 of the actuator 100 are constructed as a flexible structure, and the first cable 41 and the second cable 42 extend leftward to the mounting plate 201. An ice-breaking rocker arm 204 is provided on the lock hook 203, and is connected to the lower side area of the lock hook 203. The second end of the second cable 42 is connected to the end of the ice-breaking rocker arm 204 that is away from the lock hook 203, and the second cable 42 can drive the lock hook 203 to rotate counterclockwise through the ice-breaking rocker arm 204, to drive the lock hook 203 to move to the unlocked position.

At the same time, the suction assembly 205 comprises a first suction structure 205a and a second suction structure 205b. The first suction structure 205a has matching holes, and the rotation pin is suitable for passing through the matching holes of the first suction structure 205a and the connection rotation holes of the mounting plate 201, to rotatably install the first suction structure 205a on the upper right side of the mounting plate 201. The left side of the first suction structure 205a is rotatably connected to the second suction structure 205b, the second suction structure 205b is used to press downward on the right side of the lock hook 203, and the lower side of the first suction structure 205a is connected to the second end of the first cable 41. The first cable 41 can drive the first suction structure 205a to rotate counterclockwise, so that the second suction structure 205b can drive the lock hook 203 to rotate clockwise, so that the lock hook 203 can rotate to the locked position.

In the working process, referring to FIGS. 12-13, when the vehicle door is locked and the external temperature is too low, the lock hook 203 may be iced. When the user controls the vehicle door to be unlocked, the backward force of the unlocking process is insufficient, and the lock hook 203 will remain in the locked position, causing the vehicle door to be unable to open. At this time, the driver can drive the output rotor 3 to backward, the engaging part can pull the second cable 42, the second end of the second cable 42 can pull the ice-breaking rocker arm 204 to rotate counterclockwise around the rotation pin, the ice-breaking rocker arm 204 can drive the lock hook 203 to rotate counterclockwise to move away from the locking arm assembly 202 and switch to the unlocked position, to achieve the ice-breaking unlocking of the vehicle door. Referring to FIGS. 9-11, when the lock hook 203 is not in the closed position, the driver can drive the output rotor 3 to rotate in the forward direction, the engaging part can pull the first cable 41, the second end of the first cable 41 can pull the suction assembly 205 to rotate counterclockwise around the rotation pin, the second suction structure 205b can apply a downward force on the right side of the lock hook 203, so that the lock hook 203 can rotate clockwise to the locked position, to achieve the locking of the vehicle door.

Through the above-mentioned configuration, the output rotor 3 can be driven to rotate forward by the driver, so that the first cable 41 drives the lock hook 203 and the locking arm assembly 202 to lock, thereby realizing the locking of the car door. Additionally, the output rotor 3 can be driven to rotate backward by the driver, so that the second cable 42 can drive the ice-breaking rocker arm 204 to drive the lock hook 203 away from the locking arm assembly 202, thereby realizing the de-icing unlocking of the car 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 for reducing costs.

In some embodiments of the present application, the lock hook 203 includes a first fitting part 203a and a second fitting part 203b, the locking arm assembly 202 includes a first locking part 202a and a second locking part 202b, and the door lock assembly 200 includes a half-locked state and a fully-locked state. In the half-locked state, the first fitting part 203a engages with the first locking part 202a and the second fitting part 203b does not engage with the second locking part 202b, and in the fully-locked state, the second fitting part 203b engages with the second locking part 202b and the first fitting part 203a does not engage with the first locking part 202a.

For example, referring to FIGS. 8-11, the lock hook 203 can have the first fitting part 203a and the second fitting part 203b arranged sequentially in a counterclockwise direction on the outer side of the lock hook 203, and the first fitting part 203a is located on the side of the second fitting part 203b away from the mounting plate 201. The locking arm assembly 202 has a first locking part 202a and a second locking part 202b, where the first locking part 202a is located on the side of the second locking part 202b away from the mounting plate 201 and faces the first fitting part 203a.

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 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 fitting part 203a and the second fitting part 203b are spaced apart from the locking arm assembly 202, so the car door can move freely relative to the body. As shown in FIG. 10, when the door lock assembly 200 is in the half-locked state, the lock hook 203 is in the half-locked position, and the first fitting part 203a engages with the first locking part 202a, and the second fitting part 203b does not engage with the second locking part 202b, so the locking arm assembly 202 can prevent the lock hook 203 from rotation clockwise to the unlocked position to realize self-unlocking, and the user can drive the lock hook 203 to move to the unlocked position through the inner or outer handle of the car door to unlock the door. As shown in FIG. 11, when the door lock assembly 200 is in the fully-locked state, the lock hook 203 is in the locked position, and the second fitting part 203b of the lock hook 203 engages with the first locking part 202a of the locking arm assembly 202, and the first fitting part 203a does not engage with the first locking part 202a, so the locking arm assembly 202 can prevent the lock hook 203 from rotation clockwise to the unlocked position to realize self-unlocking, and the user cannot drive the lock hook 203 to rotate through the inner or outer handle of the car door, so the car door is fully locked.

It is understandable that by configuring the door lock assembly 200 to have multiple different states, the car door can have various states to meet the actual needs of the user, which is beneficial for improving user satisfaction.

In some embodiments of this application, the suction assembly 205 rotates to drive the lock hook 203 to rotate, so that the door lock assembly 200 switches from the half-locked state to the fully-locked state. For example, referring to FIGS. 10-11, when the door lock assembly 200 is in the half-locked state, the lock hook 203 is in the half-locked position. At this time, the output rotor 3 can be driven to rotate forward, the fitting part pulls the first cable 41, and the second end of the first cable 41 can pull the first suction structure 205a to rotate counterclockwise around the pivot pin. The second suction structure 205b can apply a downward force on the right side of the lock hook 203, causing the lock hook 203 to rotate clockwise to the locked position. The second fitting part 203b of the lock hook 203 engages with the second locking part 202b of the locking arm assembly 202, so as to switch the door lock assembly 200 to the fully-locked state. In this way, the locking process of the car door is simplified, which is beneficial for improving the reliability of the car door locking and enhancing the safety of the passengers.

Additionally, the driver can drive the output rotor 3 to rotate backward, so that the second cable 42 can drive the ice-breaking rocker arm 204 to drive the lock hook 203 away from the locking arm assembly 202, thereby realizing the ice-breaking unlocking of the car 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 thus improving the overall performance of the vehicle 300.
