The automotive lighting system includes various lighting devices such as the vehicle's headlights, taillights, and turn signals, and the lighting actuator is responsible for executing corresponding control commands to turn on, turn off, blink, etc. these lighting devices as needed.

[0003] Currently, during the execution process, the actuator generates relatively high noise, which causes the user to hear the noise inside the vehicle, affecting the comfort of the user while driving the car, and also bringing a bad experience when the user experiences the car. There are areas for improvement. For this reason, this application proposes a visual angle actuator to solve the above problems. Utility Model Content

[0004] In view of the deficiencies of the prior art, the present utility model provides a visual angle actuator, which overcomes the deficiencies of the prior art and aims to solve the problems in the background art.

[0005] To achieve the above object, this application adopts the following technical solution: A visual angle actuator includes a housing and a driver. A high-precision stepper motor is fixedly assembled on the inner wall of the housing. The power output shaft of the high-precision stepper motor is fixedly connected to a driving gear. A limiting tube is fixedly assembled on the inner wall of the housing. A lead screw is rotatably connected to the inner wall of the limiting tube. A driven gear is fixedly assembled on the outer edge of the lead screw. A slider is threadedly connected to the outer edge of the driven gear. Two guiding blocks are symmetrically and fixedly assembled on the outer side of the slider. Two guiding rails are symmetrically formed on the inner wall of the housing, and fixing rods are fixedly assembled on the inner walls of the two guiding rails. An actuator body is fixedly assembled on the top of the slider.

[0006] As a preferred embodiment, two mounting rods are symmetrically and fixedly assembled on the outer side of the housing, and positioning holes are formed in the inner walls of the ends of the two mounting rods away from the housing.

[0007] By adopting the above technical solution, bolts can be inserted into the inner walls of the two positioning holes and fixed to the vehicle body, thereby achieving the fixation of the device.

[0008] As a preferred embodiment, a positioning pin is fixedly connected to the side of the driving gear away from the high-precision stepper motor, and the end of the positioning pin away from the driving gear is rotatably connected to the inner wall of the housing.

[0009] By adopting the above technical solution, the driving gear during rotation can be limited, ensuring the stability of the driving gear during rotation and preventing it from wobbling during rotation.

[0010] As a preferred embodiment, one end of the lead screw away from the limit tube is fixedly connected with a limit rod, and the limit rod is rotatably connected to the inner wall of the housing.

[0011] By adopting the above technical solution, the stability of the lead screw during rotation can be ensured, and then the limit tube can be used to limit both ends of the lead screw, ensuring that it can continuously rotate in the initial state.

[0012] As a preferred embodiment, the driving gear and the driven gear are in the same cross-section, and the teeth of the driving gear and the driven gear are meshed with each other.

[0013] By adopting the above technical solution, when the driving gear rotates, it can transmit the rotational force to the driven gear through the teeth, thereby driving the lead screw to rotate to adjust the positions of the slider and the actuator body, execute corresponding control commands, and enable these lighting devices to be turned on, off, flashed, etc. as required.

[0014] As a preferred embodiment, sliding holes are formed in the inner walls of both guiding blocks, and two fixing rods are arranged on the inner walls of the two sliding holes. The shapes of the guiding blocks are adapted to the inner wall shapes of the guide rails and are both arc-shaped. The two guiding blocks are slidably connected to the inner walls of the two guide rails. The guiding blocks and the fixing rods are both made of silica gel.

[0015] By adopting the above technical solution, the slider during movement can be limited, and it is ensured that the slider will not rotate together with the rotational force of the lead screw during the rotation of the lead screw. Moreover, due to the soft nature of the silica gel material of the guiding block, there will be no intense friction when sliding on the inner wall of the shape-fitting guide rail, and the noise can be reduced, achieving a silent effect.

[0016] As a preferred embodiment, the driver and the high-precision stepper motor are electrically connected.

[0017] By adopting the above technical solution, the driver can control the operation of the high-precision stepper motor to drive the driving gear and the driven gear to rotate, thereby driving the lead screw to rotate to adjust the positions of the slider and the actuator body.

[0018] Advantages of this application:

[0019] 1. The visual angle actuator controls the operation of a high-precision stepper motor through a driver to drive the rotation of the driving gear. Then, when the driving gear rotates, it can transmit the rotational force to the driven gear through the teeth, thereby driving the rotation of the lead screw to adjust the positions of the slider and the actuator body, execute corresponding control commands, and enable these lighting devices to perform operations such as turning on, turning off, and flashing as required. At the same time, the guide block can limit the position of the slider during movement, ensure that the slider does not rotate together with the rotational force of the lead screw when the lead screw rotates, and utilize the soft characteristic of the guide block made of silicone material so that there will be no intense friction when sliding on the inner wall of the guide rail with a suitable shape, and it can reduce noise and achieve a silent effect. Furthermore, it can improve the comfort of the user when operating the lights while driving a car and the good experience of the user when experiencing the car. Description of the Drawings

A slider 11 is threadedly connected to the outer edge of the driven gear 10. Two guiding blocks 12 are symmetrically and fixedly assembled on the outer side of the slider 11. Two guiding rails 14 are symmetrically formed on the inner wall of the housing 1, and fixing rods 13 are fixedly assembled on the inner walls of the two guiding rails 14. An actuator body 15 is fixedly assembled on the top of the slider 11.

[0027] Refer to Figure 1 , Two mounting rods 2 are symmetrically and fixedly assembled on the outer side of the housing 1, and positioning holes 3 are formed in the inner walls of the ends of the two mounting rods 2 away from the housing 1, so that bolts can be inserted into the inner walls of the two positioning holes 3 and the vehicle body for fixed installation, thereby realizing the fixation of the device.

[0028] Refer to Figure 2 , A positioning pin 6 is fixedly connected to the side of the driving gear 5 away from the high-precision stepper motor 4. The end of the positioning pin 6 away from the driving gear 5 is rotatably connected to the inner wall of the housing 1, so that the driving gear 5 during rotation can be limited, ensuring the stability of the driving gear 5 during rotation and ensuring that it will not swing during rotation.

[0029] Refer to Figure 2 and Figure 3 , A limiting rod 9 is fixedly connected to the end of the lead screw 8 away from the limiting tube 7. The limiting rod 9 is rotatably connected to the inner wall of the housing 1, so that the stability of the lead screw 8 during rotation can be ensured. Furthermore, the two ends of the lead screw 8 can be limited in cooperation with the limiting tube 7, ensuring that it can continuously rotate in the initial state.

[0030] Refer to Figure 2 and Figure 3 , The driving gear 5 and the driven gear 10 are in the same cross-section, and the teeth of the driving gear 5 and the driven gear 10 are meshed with each other, so that when the driving gear 5 rotates, it can transmit the rotational force to the driven gear 10 through the teeth, thereby driving the lead screw 8 to rotate to adjust the positions of the slider 11 and the actuator body 15, execute corresponding control commands, and enable these lighting devices to perform operations such as turning on, turning off, and flashing as required.

[0031] Refer to Figure 3 and Figure 4, sliding holes are formed in the inner walls of both guiding blocks 12, and two fixing rods 13 are arranged on the inner walls of the two sliding holes.

Moreover, due to the soft nature of the guiding blocks 12 made of silica gel material, there will be no intense friction when sliding on the inner walls of the guiding rails 14 with adapted shapes, and the noise can be reduced, achieving a silent effect.

[0032] Refer to Figure 1 , the driver 16 and the high-precision stepper motor 4 are electrically connected, so that the driver 16 can control the operation of the high-precision stepper motor 4 to drive the driving gear 5 and the driven gear 10 to rotate, and then drive the lead screw 8 to rotate to adjust the positions of the slider 11 and the actuator body 15.

[0033] Working principle: When using this device, first, bolts can be inserted into the inner walls of the two positioning holes 3 and fixed to the vehicle body to fix the housing 1. Then, the driver 16 can control the operation of the high-precision stepper motor 4 to drive the driving gear 5 to rotate. Then, when the driving gear 5 rotates, it can transmit the rotating force to the driven gear 10 by means of the teeth, and then drive the lead screw 8 to rotate to adjust the positions of the slider 11 and the actuator body 15, execute corresponding control commands, and make these lighting devices turn on, turn off, flash, etc. as required. At the same time, the guiding block 12 can limit the slider 11 during movement, and it is ensured that the slider 11 will not rotate together with the rotating force of the lead screw 8 when the lead screw 8 rotates. Moreover, due to the soft nature of the guiding block 12 made of silica gel material, there will be no intense friction when sliding on the inner walls of the guiding rails 14 with adapted shapes, and the noise can be reduced, achieving a silent effect.
