Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and more specifically to a protective film for automotive headlights used to prevent glare. Background Technology

[0002] With the rapid development of the automotive industry, vehicle lights, as an important component of automobiles, not only relate to driving safety but also affect driving comfort. Traditional car lights are prone to glare at night or in low-light conditions, especially when oncoming vehicles are approaching. The intense light can cause discomfort to the driver's eyes and even lead to traffic accidents.

[0003] In practical use, most existing automotive headlight protective films are statically designed and cannot automatically adjust their light transmittance according to changes in ambient light. This results in limited anti-glare effects under complex lighting conditions, failing to effectively alleviate glare problems. Furthermore, they are prone to attracting dust, oil, and other contaminants, which affects lighting performance and aesthetics, leading to decreased light transmittance and impacting headlight illumination. In addition, frequent cleaning of the protective film not only increases maintenance costs but may also damage the film due to improper cleaning. Therefore, we propose an anti-glare automotive headlight protective film to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the problem that most automotive headlight protective films are statically designed and cannot automatically adjust their light transmittance according to changes in ambient light. This results in limited anti-glare effects under complex lighting conditions, an inability to effectively alleviate glare, and an susceptibility to dust, oil, and other contaminants, which in turn affects the lighting effect and aesthetics, leading to a decrease in light transmittance and impacting the headlight's illumination. Therefore, this invention provides an anti-glare automotive headlight protective film.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A protective film for automotive headlights to prevent glare includes a protective film body. A micro-groove is formed on the top edge of the protective film body, and a control circuit and a photosensor are embedded within the micro-groove. The control circuit and photosensor are encapsulated using epoxy resin material, and the encapsulated control circuit and photosensor are flush with the surface of the protective film body. The protective film body includes a substrate layer, a smart dimming layer on top of the substrate layer, an anti-glare layer on top of the smart dimming layer, a self-cleaning layer on top of the anti-glare layer, and a protective layer on top of the self-cleaning layer.

[0007] As a further description of the above technical solution, the substrate layer is made of polycarbonate material with a thickness of 0.2-0.6 mm.

[0008] As a further description of the above technical solution, the intelligent dimming layer is an electrochromic polymer coating with a thickness of 0.05-0.1 mm.

[0009] As a further description of the above technical solution, the self-cleaning layer is a siloxane coating with a thickness of 0.01-0.05 mm.

[0010] As a further description of the above technical solution, the protective layer is a polytetrafluoroethylene coating with a thickness of 0.01-0.04 mm.

[0011] As a further description of the above technical solution, an adhesive layer is provided at the bottom of the substrate layer for fixing the protective film to the surface of the vehicle lamp, and the adhesive layer is made of acrylic pressure-sensitive adhesive.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention, through the design of an anti-glare layer and a self-cleaning layer, effectively reduces glare from vehicle lights while minimizing the adhesion of dust and oil, maintaining the light transmittance and illumination effect of the lights. A light sensor detects ambient light intensity in real time, and the control circuit dynamically adjusts the light transmittance of the intelligent dimming layer based on the detection results, achieving a highly efficient anti-glare effect.

Figure 1-2 As shown, the protective film body 1 includes a micro-groove 2 on the top edge of the protective film body 1. A control circuit 3 and a light sensor 4 are embedded in the micro-groove 2. The control circuit 3 and the light sensor 4 are encapsulated with epoxy resin material, and the encapsulated control circuit 3 and the light sensor 4 are flush with the surface of the protective film body 1. The protective film body 1 includes a substrate layer 101. A smart dimming layer 102 is provided on the top of the substrate layer 101. An anti-glare layer 103 is provided on the top of the smart dimming layer 102. A self-cleaning layer 104 is provided on the top of the anti-glare layer 103. A protective layer 105 is provided on the top of the self-cleaning layer 104.

[0019] In this embodiment, the control circuit 3 and the photosensor 4 are encapsulated with waterproof and dustproof materials, such as epoxy resin, to ensure stable operation in harsh environments. The encapsulated photosensor 4 and control circuit 3 are flush with the surface of the protective film, avoiding protrusions that could affect the overall appearance and use of the protective film. Simultaneously, the embedded design avoids protrusions from external components, allowing the protective film to fit more closely to the headlight surface, improving the user experience. The control circuit 3 is powered by the headlight power supply and can be connected to the headlight circuit via flexible wires to ensure power supply stability. The design of the anti-glare layer 103 and the self-cleaning layer 104 effectively reduces glare from the headlights while reducing the adhesion of dust and oil, maintaining the headlight's light transmittance and illumination effect. The photosensor 4 can detect ambient light intensity in real time, and the control circuit 3 dynamically adjusts the light transmittance of the intelligent dimming layer 102 based on the detection results, thereby achieving a highly efficient anti-glare effect. It can automatically adjust the light transmittance according to changes in ambient light, achieving dynamic anti-glare and significantly improving driving safety and driving experience.

[0020] Furthermore, the substrate layer 101 is made of polycarbonate material with a thickness of 0.2-0.6 mm, and has high light transmittance, UV resistance, and impact resistance.

[0021] Furthermore, the intelligent dimming layer 102 is an electrochromic polymer coating with a thickness of 0.05-0.1 mm, which can switch between transparent and semi-transparent states according to external electrical signals to achieve dynamic adjustment of light transmittance.

[0022] Furthermore, the anti-glare layer 103 is composed of nano-indium tin oxide particles and optical resin, with the nano-particles uniformly distributed in the optical resin to form a micron-level uneven structure, which can effectively scatter light and reduce glare.

[0023] Furthermore, the self-cleaning layer 104 is a siloxane coating with a thickness of 0.01-0.05 mm, which has superhydrophobic and photocatalytic self-cleaning functions.

[0024] Furthermore, the protective layer 105 is a polytetrafluoroethylene coating with a thickness of 0.01-0.04 mm, which has excellent hydrophobicity, abrasion resistance and weather resistance.

[0025] Furthermore, an adhesive layer 106 is provided at the bottom of the substrate layer 101 to fix the protective film to the surface of the vehicle headlight. The adhesive layer 106 is made of acrylic pressure-sensitive adhesive, which has good adhesion and removability, making it easy to install and replace.

[0026] The working principle of this utility model is as follows: In use, the design of the anti-glare layer 103 and the self-cleaning layer 104 can effectively reduce the glare generated by the headlights, while reducing the adhesion of dust and oil stains, maintaining the light transmittance and lighting effect of the headlights. The light sensor 4 can detect the ambient light intensity in real time, and the control circuit 3 can dynamically adjust the light transmittance of the intelligent dimming layer 102 according to the detection results, thereby achieving a highly efficient anti-glare effect. It can automatically adjust the light transmittance according to the changes in ambient light, achieve dynamic anti-glare, and significantly improve driving safety and driving experience.
