[0022] The present invention is described in detail below in conjunction with specific implementation cases. The following implementation cases will help those skilled in the art to further understand the present invention, but will not limit the present invention in any form.

[0023] like Figure 1 — Figure 6As shown, the present invention relates to a light source assembly with a screen lighting structure, including a light source assembly, wherein the light source assembly is a lens light source assembly, wherein the lens light source assembly includes a high and low beam assembly 1 and a lens assembly 2, and a screen 3 is arranged in front of the high and low beam assembly 1, and the screen 3 and the high and low beam assembly 1 are driven by a switching mechanism to switch and light up each other. In this scheme, the screen 3 is arranged in front of the high and low beam assembly 1, that is, the screen 3 blocks the front of the high and low beam assembly 1, when the car starts, the screen is lit up, and pictures or videos are displayed on the screen. In actual products, the screen is used as a daytime running light, and a chip is arranged in the screen, and preset pictures or videos can be controlled by a mobile phone application. The screen 3 is arranged in front of the high and low beam assembly 1. After lighting, through the lens assembly, the pictures or videos displayed on the screen 3 in the car headlights can be clearly and eye-catchingly seen. According to personal preferences, the pictures or videos can be various, showing personal colors, making the car headlight modification more personalized and attracting more attention. However, when the high and low beam assembly 1 is turned on, the switching mechanism moves the screen 3 from its original position, that is, the screen 3 no longer blocks the high and low beam assembly 1. After the high and low beam assembly 1 is lit, the screen 3 goes out and the car headlights can be used normally.

[0024] In the first embodiment, the switching mechanism includes two vertical plates 20, which are respectively fixedly connected to the front sides of the light source bracket 5, and a lifting seat 21 is arranged between the two vertical plates 20. The screen 3 is fixed on the lifting seat 21, and the lifting seat is driven up and down by the lifting structure. When in use, the lifting structure drives the screen 3 to rise or fall, and the screen 3 is shifted so as not to block the high and low beam assembly 1, so as to achieve the purpose of switching and lighting with the high and low beam assembly 1.

[0025] There are many technical solutions for the lifting structure, for example, racks 22 are arranged on each of the two vertical plates 20, a dual-output shaft motor 23 is arranged on the lifting seat 21, two output shafts of the dual-output shaft motor 23 are respectively connected to a connecting rod 24, a gear 25 is arranged on the connecting rod 24, and the gear 25 is meshed with the rack 22. When working, the two output shafts of the dual-output shaft motor 23 rotate, thereby driving the gear 25 on the connecting rod 24 to move on the rack 22, so as to achieve the purpose of lifting or lowering.

[0026] Furthermore, the high and low beam assembly 1 includes a light source bracket 5, a high and low beam lamp bead 6 is arranged on the light source bracket 5, a reflective bowl 7 corresponding to the high and low beam lamp bead is arranged under the light source bracket 5, and a high and low beam adjustment mechanism is arranged at the front of the light source bracket 5. In an actual product, the high and low beam lamp bead 6 is fixed on the lamp bead circuit board 31, and there can be two groups of high and low beam lamp bead 6, lamp bead circuit board 31 and reflective bowl 7, and the high and low beam of the automobile headlight is adjusted by the high and low beam adjustment mechanism.

[0027] Furthermore, the high and low beam adjustment mechanism includes a high and low beam adjustment plate 8, which corresponds to the high and low beam lamp beads 6. A solenoid valve 9 is arranged on the light source bracket 5, and the solenoid valve 9 is connected to the adjustment rod 10, and the adjustment rod 10 is connected to the adjustment frame 11, and the adjustment frame 11 is connected to the high and low beam adjustment plate 8. When in use, the solenoid valve 9 drives the high and low beam adjustment plate 8 to rise and fall, so as to achieve the purpose of adjusting the high and low beam of the automobile headlight. That is, the initial state is low beam, and the high and low beam adjustment plate 8 blocks part of the high and low beam lamp beads 6 and the reflective bowl 7; when in high beam, the solenoid valve 9 drives the high and low beam adjustment plate 8 to rise, and the high and low beam adjustment plate 8 does not block the high and low beam lamp beads 6 and the reflective bowl 7.

[0028] Furthermore, a return spring 12 is sleeved on the adjustment rod 10, the upper end of the return spring 12 contacts the valve body of the electromagnetic valve 9, and the lower end of the return spring 12 contacts the adjustment frame 11. With the return spring 12, when the electromagnetic valve 9 is powered off, the high and low beam adjustment plate 8 is automatically reset under the action of the return spring 12, saving electricity.

[0029] Furthermore, the high and low beam adjustment plate 8 may be a curved plate, which has a better adjustment effect.

[0030] Furthermore, a heat dissipation device is arranged on the light source bracket 5, and the heat dissipation device includes a heat dissipation bracket 30, a heat dissipation fan 32 is arranged on the heat dissipation bracket 30, and a corresponding heat dissipation mesh cover 33 is arranged on the light source bracket 5. When the heat dissipation fan works, the heat emitted by the high and low beam lamp beads 6 is dissipated out of the light source assembly through the heat dissipation mesh cover, thereby reducing the internal temperature of the light source assembly and extending the service life of the high and low beam lamp beads 6.

[0031] Furthermore, the lens assembly includes a lens barrel 15 , which is fixed on the light source bracket 5 , and a lens 16 is arranged on the lens barrel 15 .

[0032] Furthermore, a limiting gap 26 is provided on each of the two vertical plates 20, a limiting rod 27 is connected to each side of the lifting seat 21, a limiting block 28 is provided on the limiting rod 27, and the limiting block 28 cooperates with the limiting gap 26. With the cooperation between the limiting block 28 and the limiting gap 26, the screen 3 can be shifted accurately.

[0033] The above specific implementation modes are used to explain the present invention rather than to limit the present invention. Any modification and change made to the present invention within the spirit of the present invention and the protection scope of the claims shall fall within the protection scope of the present invention.
