Based on the feedback from the position sensing component 3, the transmission component 2 can controllably drive the dimming component 1 to rotate to the set light pattern position.
[0032] Specifically, the utility model provides a headlight light type adjustment structure for adjusting different light types of vehicle headlights to meet the needs of different scenarios. The dimming component 1 is driven to rotate by the transmission component 2, thereby realizing the function of switching between multiple light types, meeting the lighting needs of the vehicle under different road conditions, and ensuring driving safety.
[0033] In a preferred embodiment, referring to Figure 2 , the dimming component 1 includes,
[0034] Dimming axis 11;
[0035] Bearings 12 are respectively provided at both ends of the dimming shaft 11, and the dimming shaft 11 rotates based on the rotation of the bearings 12;
[0036] The first gear 13 is disposed on the inner side of the bearing 12 at the first end of the dimming shaft 11 .
[0037] Specifically, the first gear 13 is assembled with the dimming shaft 11 by interference pressing, and a bearing 12 is installed on both sides of the dimming shaft 11 to ensure that the dimming shaft 11 can rotate arbitrarily. The bearings 12 are fixed with the dimming shaft 11 by interference pressing.
[0038] In a preferred embodiment, referring to Figure 3 , transmission component 2 includes,
[0039] Motor 21;
[0040] Motor gear 22, connected to motor 21;
[0041] The second gear 23 is located between the first gear 13 and the motor gear 22 , and the second gear 23 is meshed with the first gear 13 and the motor gear 22 .
[0042] Specifically, the motor gear 22 is pressed onto the motor 21, and the motor 21, the second gear 23, and the dimming component 1 are installed in the bracket 4. Through the rotation of the motor 21, the motor gear 22 drives the second gear 23 to rotate, and then drives the first gear 13 to rotate. Under the action of the bearing 12, the dimming shaft 11 rotates to the desired position with the motor 21.
[0043] In a preferred embodiment, referring to Figure 2 , the position sensing component 3 includes a magnet 31, which is located outside the bearing 12 at the second end of the dimming shaft 11;
[0044] The position sensing assembly 3 further includes a magnet housing 32 located outside the bearing 12 at the second end of the dimming shaft 11 , and a magnet 31 is disposed in the magnet housing 32 .
[0045] Specifically, the magnet 31 is installed in the magnet housing 32 and fixed by riveting, and the magnet housing 32 and the dimming shaft 11 are assembled by interference press fit.
[0046] In a preferred embodiment, referring to Figure 4 , a circuit board cover 6 is further provided on the bracket 4, and the circuit board cover 6 is close to the second end of the dimming component 1;
[0047] A circuit board 7 is provided on one side of the circuit board cover 6 close to the dimming component 1;
[0048] A chip 8 for identifying the angular position of the position sensing component 3 is provided on the circuit board 7 .
[0049] Specifically, the switching of different scenes and different light types is achieved by generating Hall induction between the magnet 31 on the dimming axis 11 and the chip 8, and controlling the rotation of the motor 21 in combination with the module instruction to realize the control of the specific light type.
[0050] Magnet 31 and chip 8 use Hall effect sensing to provide feedback on the position of dimming axis 11. Chip 8 is attached to circuit board 7, which is fixed to circuit board cover 6, which is fixed to bracket 4, thus ensuring that chip 8 is fixed to bracket 4. The relative position of magnet 31 and chip 8 is ensured, and the module program connects to circuit board 7 and motor 21 to control the rotation of motor 21. The angular position of magnet 31 is then fed back through Hall effect sensing, thereby achieving the effect of controlling the rotation angle of dimming axis 11. By controlling the different structural features and angular positions of dimming axis 11, different light patterns can be achieved to meet the needs of different scenarios.
[0051] In a preferred embodiment, it further includes a motor cover 5, which is located above the dimming component 1;
[0052] A transmission rod 9 is installed at the front end of the bracket 4.
[0053] Specifically, a motor cover 5 is installed above the dimming assembly 1 to protect the motor 21, and a transmission rod 9 is fixed to the front end of the bracket 4 with screws. The dimming assembly 1, motor 21, and second gear 23 are installed on the bracket 4 and fixed with the motor cover 5. The present invention has a simple structure and is easy to assemble. Moreover, the control of the motor 21 ensures a variety of light patterns, which can better meet the lighting requirements of different driving scenarios.
[0054] In the present invention, one side of the dimming shaft 11 is fixed to the first gear 13 and is equipped with a bearing 12, and the other side of the dimming shaft 11 is fixed to the magnet 31 and is equipped with a bearing 12. The second gear 23 is located between the first gear 13 and the motor gear 22. Driven by the motor 21 to rotate, under the action of the bearings 12 on both sides, the dimming shaft 11 rotates with the motor 21, and can present different light pattern structures. The magnet 31 on the other side of the dimming shaft 11 and the chip 8 generate Hall induction, and the specific position of the dimming shaft 11 under different light patterns is controlled by the module program, thereby realizing a variety of light pattern effects of the car light.
[0055] In summary, this application provides a headlight pattern adjustment structure located inside a vehicle headlight. The angular position of magnet 31 is identified by Hall effect sensing between magnet 31 and chip 8. Since the positions of magnet 31 and dimming axis 11 are relatively fixed, the position of dimming axis 11 can also be identified. The module program controls the rotation of motor 21, and chip 8 identifies the angular position of magnet 31, thereby rotating dimming axis 11 to the corresponding light pattern angle position to present different light pattern effects. This ensures that the headlight has different corresponding light patterns under different road conditions to ensure vehicle driving safety while meeting the diverse needs of drivers.
