The widespread application of automatic headlight adjustment systems has not only improved the overall performance of the vehicle, but has also become one of the important considerations for consumers to choose vehicles.

[0038] Example 1 Reference Figure 1 and Figure 2A headlamp rotary actuator comprises a mounting box 1, a control component 2 and an adjustment component 3. The control component 2 and the adjustment component 3 are respectively mounted in the mounting box 1, and the control component 2 is connected to the adjustment component 3, so that the control component 2 is used to control the adjustment component 3 to work, so that the adjustment component 3 is used to accurately adjust the headlamp, thereby enabling the headlamp to be accurately adjusted under various working conditions, especially maintaining high working reliability under extreme weather conditions.

[0039] Reference Figure 3 The installation box 1 includes a shell 11 and a cover plate 12. The shell 11 and the cover plate 12 are detachably connected. In this embodiment, the shell 11 and the cover plate 12 are fixed by bolts, and a clearance groove 111 is provided on a side of the shell 11 away from the cover plate 12.

[0040] Reference Figure 2 and Figure 3 The control assembly 2 includes a PCB board 21, a first detection member 22 and a second detection member 23. The PCB board 21 is installed in the housing 11, and the first detection member 22 and the second detection member 23 are installed on the PCB board 21 respectively. A plug interface 24 is provided on the side of the PCB board 21 away from the first detection member 22, and the plug interface 24 is provided through the clearance groove 111. This design facilitates the access of external signal lines, reduces the complexity of wiring, and is also convenient for subsequent maintenance and replacement.

[0041] The adjustment component 3 includes a driving member 31 and a transmission member 32. The driving member 31 is installed in the housing 11 and is electrically connected to the PCB board 21, and the driving member 31 is arranged corresponding to the first detection member 22. In this embodiment, the first detection member 22 is a Hall element, and the driving member 31 is a BLDC motor, so that the first detection member 22 is used to detect the rotation angle of the driving member 31.

[0042] The transmission member 32 includes a first gear 321, a second gear 322, a third gear 323, a fourth gear 324, a transmission shaft 325 and an output shaft 326. The first gear 321 is coaxially and fixedly connected to the output end of the driving member 31, the transmission shaft 325 and the output shaft 326 are respectively rotatably connected in the housing 11 and are arranged parallel to each other, the second gear 322 and the third gear 323 are respectively coaxially mounted on the transmission shaft 325, the fourth gear 324 is coaxially mounted on the output shaft 326, the first gear 321 and the second gear 322 are meshed with each other, and the third gear 323 and the fourth gear 324 are meshed with each other, so that the driving member 31 can realize accurate transmission of the output shaft 326 through the multi-stage gear set composed of the first gear 321, the second gear 322, the third gear 323 and the fourth gear 324.

[0043] In this embodiment, the module of the first gear 321 is smaller than the module of the second gear 322, and the module of the third gear 323 is smaller than the module of the fourth gear 324, which can provide a larger transmission ratio, thereby more stably controlling the rotation of the output shaft 326.

[0044] Reference Figure 1 and Figure 2 One end of the output shaft 326 extends out of the cover plate 12 and is connected to a connecting plate 33, which is used to connect to the headlight, so that the output shaft 326 can drive the headlight to rotate through the connecting plate 33 to achieve angle adjustment of the headlight.

[0045] One end of the output shaft 326 away from the connecting plate 33 is connected to the second detection member 23. In this embodiment, the second detection member 23 is a potentiometer, so that the second detection member 23 is convenient for detecting the rotation angle of the output shaft 326. The cooperation between the first detection member 22 and the second detection member 23 significantly improves the adjustment accuracy of the rotary actuator, so that the headlamp can be accurately adjusted under various working conditions, especially maintaining high working reliability under extreme weather conditions.

[0046] Reference Figure 2 and Figure 4 The output shaft 326 is integrally formed with a positioning block 3261 at one end close to the connecting plate 33. The positioning block 3261 is non-circular. In this embodiment, the positioning block 3261 is rectangular. The connecting plate 33 is provided with a positioning groove 331. The positioning block 3261 is inserted into the positioning groove 331 and fits with the inner wall of the positioning groove 331, so that the output shaft 326 and the connecting plate 33 are not easy to rotate relative to each other.

[0047] Reference Figure 1 and Figure 2 , a connecting piece 332 is threadedly connected to the connecting plate 33. In this embodiment, the connecting piece 332 is a bolt, and one end of the connecting piece 332 is threadedly connected to the positioning block 3261, which is conducive to reducing the possibility of the connecting piece 332 and the output shaft 326 being away from each other, thereby ensuring the synchronous rotation of the connecting plate 33 and the output shaft 326, and avoiding angle deviation caused by looseness.

[0048] The implementation principle of the headlamp rotation actuator of the embodiment of the present application is as follows: when the angle of the headlamp needs to be adjusted, the driving member 31 works to drive the first gear 321 to rotate, and the first gear 321 drives the output shaft 326 to rotate through the second gear 322, the third gear 323 and the fourth gear 324 in sequence, and the output shaft 326 drives the headlamp to rotate through the connecting member 332. At the same time, the first detection member 22 detects the rotation angle of the driving member 31, and the second detection member 23 detects the rotation angle of the output shaft 326, and feeds back the detection data to the PCB board 21 for processing, thereby realizing accurate adjustment of the headlamp.

[0049] In this embodiment, the multi-stage gear design ensures the stability and accuracy of the output shaft 326, reduces the error in the transmission process, improves the overall performance of the system, and significantly improves the adjustment accuracy of the rotary actuator. The PCB board 21, the first detection member 22, the second detection member 23, the driving member 31, the first gear 321, the second gear 322, the third gear 323, the fourth gear 324, the transmission shaft 325 and the output shaft 326 are integrated in the installation box 1, which improves the compactness of the overall structure and reduces the space occupied.

[0050] Example 2 Reference Figure 5 and Figure 6 The difference between this embodiment and embodiment 1 is that a clamping assembly 4 is provided between the output shaft 326 and the connecting plate 33 .

[0051] The connecting plate 33 is provided with a plug slot 333 and a through slot 334, respectively. The plug slot 333 is connected with the through slot 334. The clamping assembly 4 includes a central column 41 and a plurality of clamping members 42. One end of the central column 41 is coaxial with the output shaft 326 and is slidably connected. The other end of the central column 41 passes through the plug slot 333 and extends out of the through slot 334. A guide block 411 is integrally formed on the central column 41.

[0052] Reference Figure 6 , a slide groove 3262 is coaxially provided on the output shaft 326. In this embodiment, the slide groove 3262 is a trapezoidal groove, and the smaller end of the slide groove 3262 passes through the end surface of the output shaft 326. One end of the center column 41 is slidably inserted in the slide groove 3262 and adapted to the shape design of the slide groove 3262.

[0053] An elastic member 43 is provided between the central column 41 and the inner wall of the slide groove 3262. In this embodiment, the elastic member 43 is a spring, so that the elastic member 43 can be used to drive the central column 41 close to the output shaft 326. This design allows a certain pre-tightening force to be maintained between the central column 41 and the output shaft 326, so that the central column 41 is not likely to slide on the output shaft 326 spontaneously.

[0054] Reference Figure 6 and Figure 7 , a plurality of clamping members 42 are respectively fixedly connected to the output shaft 326 and arranged around the central column 41, and a tapered groove 421 is formed between the plurality of clamping members 42, and the smaller end of the tapered groove 421 is arranged close to the output shaft 326. The guide block 411 is inserted into the tapered groove 421 and adapted to the shape design of the tapered groove 421. This design can achieve a firm fixation of the connecting plate 33 and the output shaft 326 through a simple insertion action, and is convenient for disassembly and maintenance.

[0055] When the connection plate 33 needs to be connected and fixed to the output shaft 326, the center column 41 is first inserted into the insertion groove 333 and passed through the through groove 334, and then the center column 41 is pulled, so that the center column 41 drives the guide block 411 to move away from the clamping member 42, and the elastic member 43 is compressed. Next, the connection plate 33 is moved toward the direction close to the output shaft 326, so that the clamping member 42 is inserted into the insertion groove 333, and then the center column 41 is released, and the elastic member 43 drives the guide block 411 to move toward the direction close to the output shaft 326 through the center column 41, so that the guide block 411 opens the multiple clamping members 42, and the multiple clamping members 42 are respectively tightly fitted on the inner wall of the insertion groove 333, thereby fixing the connection plate 33.

[0056] When it is necessary to separate the connecting plate 33 from the output shaft 326, the center column 41 is first pulled so that the clamping member 42 no longer abuts against the inner wall of the insertion slot 333, thereby facilitating the separation of the connecting plate 33 from the clamping member 42, and further facilitating the separation of the connecting plate 33 from the output shaft 326. At this time, if a headlamp is installed on the connecting plate 33, the headlamp can be removed together with the connecting plate 33, thereby simplifying the assembly process of the headlamp and the output shaft 326, and further improving the reliability and maintenance convenience of the overall device.

[0057] Reference Figure 6 The clamping member 42 is fixedly connected with an elastic clamping block 422, and the inner wall of the plug-in slot 333 is provided with a clamping slot 335. When the clamping member 42 is inserted into the plug-in slot 333, one elastic clamping block 422 is inserted into one clamping slot 335. This can increase the friction between the clamping member 42 and the plug-in slot 333 to prevent loosening due to vibration or the like.

[0058] Reference Figure 6 and Figure 8 The inner wall of the insertion slot 333 is fixedly connected with a limiting block 336. When the clamping member 42 is inserted into the insertion slot 333, a limiting block 336 is inserted between the two clamping members 42 and respectively contacts the two clamping members 42, so that the clamping member 42 is easily limited by the limiting block 336, so that the clamping member 42 is not easy to rotate in the insertion slot 333. This can further enhance the fixing effect of the clamping member 42 and ensure the stable connection between the connecting plate 33 and the output shaft 326.

[0059] The implementation principle of the second embodiment of the present application is as follows: when the connection plate 33 needs to be connected and fixed with the output shaft 326, the center column 41 is first inserted into the plug-in slot 333 and passed through the through slot 334, and then the center column 41 is pulled, so that the center column 41 drives the guide block 411 to move away from the clamping member 42, and the elastic member 43 is compressed at this time. Next, the connection plate 33 is moved in the direction close to the output shaft 326, so that the clamping member 42 is inserted into the plug-in slot 333, and the limit block 336 is inserted between the two clamping members 42. Then the center column 41 is released, and the elastic member 43 drives the guide block 411 to move in the direction close to the output shaft 326 through the center column 41, so that the guide block 411 opens a plurality of clamping members 42, and the plurality of clamping members 42 are respectively tightly fitted on the inner wall of the plug-in slot 333, and the elastic clamp block 422 is inserted into the clamping slot 335, thereby achieving the fixing of the connection plate 33.

[0060] Example 3 Reference Figure 1 and Figure 2 The difference between this embodiment and embodiment 1 is that the output shaft 326 and the transmission shaft 325 are rotatably connected to the cover plate 12, so that when the cover plate 12 is separated from the shell 11, the cover plate 12 can drive the first gear 321, the second gear 322, the third gear 323 and the fourth gear 324 to separate from the shell 11 through the output shaft 326 and the transmission shaft 325, so as to facilitate the inspection and replacement of the components in the shell 11, thereby facilitating the maintenance convenience of the equipment.

[0061] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
