[0003] According to relevant regulations, the color of car headlights can only be white or yellow. The headlight lenses are colorless and transparent. The color of the headlights is distinguished by using different colored bulbs. White light has a better nighttime illumination effect, but its penetration is poor in foggy weather. Yellow light has a better penetration effect in foggy weather, but its nighttime illumination is not as good as white light. The choice of headlights must be between the two, and it is difficult to find a balance between them. Summary of the Invention

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0029] Example 1: Please refer to Figures 1 to 6 :
[0030] This utility model proposes a color-changing automotive lens, comprising: a main frame 1, a rear transparent lens 2, and an upper electric roller 3. A front transparent lens 101 is fixedly mounted on the inner front side of the main frame 1. The rear surface of the front transparent lens 101 is a transparent flat plate structure. The front part of the front transparent lens 101 has a structure that is thicker in the middle and thinner on both sides, or thinner in the middle and thicker on both sides, to meet the requirements for focusing or scattering the light tube. Rear connecting carriages 102 are fixedly mounted on both sides of the rear of the main frame 1. The rear transparent lens 2 is mounted on the rear of the main frame 1. The front part of the rear transparent lens 2 has a transparent flat plate structure. The rear part of the rear transparent lens 2 has a structure that is thicker in the middle and thinner on both sides, or thinner in the middle and thicker on both sides, to meet the requirements for focusing or scattering the light tube. Side connecting brackets 201 are fixedly mounted on both sides of the rear transparent lens 2. Support springs 202 are fixedly mounted above and below the side connecting brackets 201. The side connecting brackets 201 and the rear connecting carriages 102 are connected through... A sliding connection is used to fix the tail end of the support spring 202 and the rear connecting slide 102. The upper part of the main frame 1 is rotatably equipped with an upper electric roller 3. The upper electric roller 3 is driven by a motor and can be stopped at a fixed angle for a long time. The upper electric roller 3 is fixedly connected to the intermediate color-changing film 301. The first end of the upper electric roller 3 meshes with the side drive gear shaft 303, and the lower end of the side drive gear shaft 303 meshes with the first end of the lower roller 302. The upper electric roller 3 and the lower roller 302 are respectively located above and below the front transparent lens 101. The intermediate color-changing film 301 is located between the front transparent lens 101 and the rear transparent lens 2. The upper electric roller 3 and the lower roller 302 simultaneously mesh with the upper and lower ends of the side drive gear shaft 303. The upper electric roller 3 and the lower roller 302 rotate synchronously to realize the synchronous unfolding and retraction of the two ends of the intermediate color-changing film 301, further reducing the wrinkles that occur in the intermediate color-changing film 301 due to inconsistent unfolding and retraction.
[0031] In this embodiment of the disclosure, such as Figure 1 , 2 As shown in Figures 3 and 6, the tail of the intermediate color-changing film 301 is fixedly connected to the lower roller 302. The lower roller 302 is rotatably set on the lower side of the main frame 1. The intermediate color-changing film 301 is composed of at least two colors. The color of the light passing through the intermediate color-changing film 301 changes, realizing the change of the color of the light passing through the front transparent lens 101. The light can be switched in foggy weather. The yellow light has stronger penetrating power in foggy weather.
[0032] In this embodiment of the disclosure, such as Figure 2 , 3 As shown in Figures 4 and 5, when the support spring 202 moves closer to the rear connecting bracket 201, the rear transparent lens 2 moves toward the front transparent lens 101 and presses down on the intermediate color-changing film 301, ensuring that the intermediate color-changing film 301 is in a flat and unfolded state, and avoiding the intermediate color-changing film 301 from moving, rolling up, or wrinkling during use.
[0033] In Example 2, based on Example 1, a hairspring is provided inside the lower winding shaft 302. The hairspring is used to realize the reset rotation of the lower winding shaft 302. The lower winding shaft 302 winds the intermediate color-changing film 301 on the outside, eliminating the need for the side drive gear shaft 303 and reducing the difficulty of assembly.
[0034] The working principle of this embodiment is as follows: The main frame 1 and the outer frame of the lamp body are connected and fixed. The light source is located behind the rear transparent lens 2. The light from the light source passes through the rear transparent lens 2, the intermediate color-changing film 301, and the front transparent lens 101 to reach the outside. When the main frame 1 is used with the daytime light, in foggy weather, the upper electric roller 3 is driven by a motor to rotate. The upper electric roller 3 drives the intermediate color-changing film 301 to move. The upper electric roller 3 winds the intermediate color-changing film 301 around its outer side, and the lower roller 302 releases the externally wound intermediate color-changing film 301. The intermediate color-changing film 301 moves vertically. The part of the intermediate color-changing film 301 between the front transparent lens 101 and the rear transparent lens 2 moves from a colorless and transparent part to a yellow semi-transparent part. The intermediate color-changing film 301 moves forward... The color change between the transparent lens 101 and the rear transparent lens 2 causes the light to pass through the intermediate color-changing film 301, thus changing the color of the light shining through the front transparent lens 101 to the outside, achieving the process of changing white light to yellow light. In foggy weather, the light switch is achieved, and the white light changes to yellow light. Yellow light has stronger penetration in foggy weather, improving the penetration and warning effect of white cold light bulbs in foggy weather. At night, the transparent part of the intermediate color-changing film 301 moves between the front transparent lens 101 and the rear transparent lens 2. The light shines white light on the road surface. At night, it is white light to meet the nighttime illumination range. After switching to yellow light, it can improve the penetration in foggy weather, thus possessing the advantages of both white light and yellow light.
[0035] The support spring 202 supports the side connecting bracket 201 and the rear transparent lens 2, which move closer to the front transparent lens 101. The rear transparent lens 2 moves and presses down on the intermediate photochromic film 301, which is pressed between the rear transparent lens 2 and the front transparent lens 101. The front and back of the intermediate photochromic film 301 are in close contact with the rear transparent lens 2 and the front transparent lens 101, ensuring that the intermediate photochromic film 301 is in a flat and unfolded state. This avoids wrinkles during the winding and moving of the intermediate photochromic film 301. Keeping the intermediate photochromic film 301 flat facilitates the passage of light and avoids the refraction and deflection of light due to wrinkles. The upper electric roller 3 and the lower roller 302 simultaneously mesh with the upper and lower ends of the side transmission gear shaft 303. The upper electric roller 3 and the lower roller 302 rotate synchronously, realizing the synchronous unfolding and retraction of both ends of the intermediate photochromic film 301, further reducing the wrinkles that may occur due to inconsistent unfolding and retraction of the intermediate photochromic film 301.
