Description

Technical Field

[0001] This utility model relates to the field of vehicle headlight anti-fog technology, and in particular to a vehicle headlight anti-fog device. Background Technology

[0002] Vehicle headlight defogging devices are functional components used to prevent fogging inside vehicle headlights due to temperature and humidity changes. They are widely used in various motor vehicle lighting systems, including automobiles and motorcycles.

[0003] Traditional vehicle headlight defogging devices mainly consist of ventilation holes and a desiccant pack. During use, the ventilation holes allow air to circulate, attempting to reduce the humidity inside the headlight. The desiccant pack absorbs moisture to reduce fogging. However, this traditional structure has significant drawbacks. While the ventilation holes can reduce humidity to some extent, humid air from the outside can still enter the headlight through them, resulting in poor defogging performance. The desiccant pack has limited moisture absorption capacity and can no longer function once it reaches saturation. Furthermore, if it is not replaced in a timely manner, fog will reappear inside the headlight, affecting the lighting effect.

[0004] Existing technologies address the problems of traditional devices by adding heating wires and temperature control modules. These methods raise the internal temperature of the headlight to prevent condensation and fogging. However, several issues remain. While the heating wires can disperse fog during continuous operation, insufficient precision in the temperature control module can lead to excessively high internal headlight temperatures. These excessively high temperatures accelerate the aging of the headlight housing and internal optical components, reducing the headlight's lifespan. Furthermore, drastic temperature changes can cause thermal stress on the headlight glass surface, potentially leading to cracking. Prolonged operation of the heating wires consumes significant energy, increasing the vehicle's electrical load. In complex and variable ambient temperatures, the temperature control module cannot accurately adjust the heating wires' operation, resulting in incomplete fog removal from the headlight. Additionally, excessively high temperatures can affect the headlight's illumination, causing light scattering and attenuation, further compromising driving safety. Utility Model Content

[0044] Working Principle: The vehicle headlight defogging device uses a mounting plate 1 as its installation base. The front defogging mechanism 2, through the coordinated operation of multiple components, solves the problems of easy fogging inside the headlight, slow fog dissipation, unstable temperature control, and insufficient protection of parts in current technologies. The mounting plate 1 provides installation support for the device. In the front defogging mechanism 2, the outer shell 201 is fixed to the right side of the mounting plate 1, and the internal left side fixing suction cup 202 firmly adsorbs the lamp post 203. The lamp post 203 serves as a carrier to mount the resistance wire 204. The resistance wire 204 heats up to dissipate the fog. The thermistor 205 can automatically adjust the temperature to ensure stable heating and avoid excessively high or low temperatures affecting the defogging effect and the lifespan of the parts. The heat film 206 on its outer wall assists in uniform heat dissipation, enhancing the defogging effect while making the heat distribution more even. The LED headlight 207 provides illumination, while the louvers 209 inside the window slots 208 on the left and right sides of the housing 201 promote air circulation, accelerate fog dissipation, and prevent fog accumulation. The inner pad 211 cushions and protects the internal parts, reducing damage to the parts from vibration. The protective component 210 on the right side protects the right-side components. The rear fixing mechanism 3 facilitates the stable installation of the device on the headlight, ensuring operational stability. The top cooling mechanism 4 reduces the internal temperature of the headlight, further improving the anti-fog effect. By controlling the temperature, fog generation is reduced from the source, resulting in better anti-fog performance. Through the coordinated work of various components, this device achieves efficient anti-fog, stable temperature control, parts protection, and stable installation, effectively solving the problems of headlight fog affecting illumination, poor temperature control, and easily damaged parts.

[0045] Furthermore, the fixing mechanism 3, through the combination of various components, solves the problems of insufficient installation stability, inconvenient disassembly, and easy displacement and detachment due to vibration of the vehicle headlight anti-fog device. The rotating shaft 301 serves as the core of rotation, and its outer wall is rotatably connected to the fixing plate 1, allowing the entire fixing mechanism 3 to rotate flexibly and easily adjust the installation angle to adapt to different vehicle headlight structures. The sliding plate 302 fixed on the left side of the rotating shaft 301 provides a flat bearing platform. The two circular slots 303 on the top can accommodate screws 304, which can rotate within the slots 303. By tightening the screws 304, the component to be installed can be fixed on the sliding plate 302, and by loosening them, disassembly can be achieved. The design makes installation and disassembly operations more convenient and efficient. The L-shaped connecting plate 305 at the bottom of the fixing plate 1, through its unique L-shaped structure, can be firmly connected to the vehicle headlight body or other external structures. The design increases the contact area and enhances connection stability. By rotating shaft 2 301 to adjust the slide plate 302 to a suitable position, screws 304 are passed through the circular groove 303 and the corresponding holes of the headlight mounting part, and screws 304 are tightened to fix the slide plate 302 to the headlight component. Finally, L-shaped connecting plate 305 is used to connect to the fixing point of the headlight to form a double fixing structure. During use, the structural design of L-shaped connecting plate 305 can effectively disperse the impact force generated by vibration and prevent the device from shifting due to vibration during vehicle operation. The cooperation between rotating shaft 2 301 and fixing plate 1 ensures that the rotating parts will not loosen, and the tightness of screws 304 also ensures the stability of the load-bearing parts, realizing the stable installation of the device on the headlight, solving the problems of loose installation and inconvenient disassembly, and improving the practicality and reliability of the headlight anti-fog device.
