Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automotive fog light technology, specifically, it relates to a dynamically adjustable fog light. Background Technology
[0002] In severe weather conditions such as heavy fog and heavy rain, car fog lights play a crucial role. They provide effective illumination for the vehicle, helping the driver see the road ahead and making it easier for other vehicles to spot the car, thereby reducing the occurrence of traffic accidents.
[0003] Currently, most fog lights on the market are designed with a fixed angle, and their illumination direction and range cannot be adjusted according to actual road conditions and weather. However, different fog concentrations, road slopes, and vehicle driving conditions significantly affect the illumination requirements of fog lights. For example, in dense fog, fog lights need a more concentrated beam and a shorter illumination distance to avoid light being reflected by the fog and affecting the driver's vision; in light fog, it is necessary to appropriately expand the illumination range and increase the illumination distance. Fixed-angle fog lights obviously cannot meet these dynamically changing needs, posing certain potential hazards to driving safety.
[0004] Therefore, developing a fog lamp that can dynamically adjust the illumination angle according to actual conditions has become an urgent problem to be solved by those skilled in the art. Utility Model Content
[0005] In view of this, the technical problem to be solved by this utility model is to provide a dynamically adjustable fog light, which avoids the problem that the angle of the previous fog lights was fixed and could not be dynamically adjusted according to the actual road conditions and weather conditions, thus affecting driving safety.
[0006] To solve the above-mentioned technical problems, this utility model discloses a dynamically adjustable fog light, comprising: Rear housing; The radiator is fixed to the rear housing by screws and has heat dissipation fins exposed on the rear side of the rear housing. An LED light panel is installed on the front side of the radiator, and the LED light panel has fog light beads; A lens is pivotally mounted on the rear housing and covers the fog light bulb. One side of the lens is provided with an adjustment pin that guides the rear side, and the adjustment pin is provided with a toothed part. The adjusting screw of the meshing rack and tooth section is mounted on the rear housing via a bearing and has a drive end exposed above the rear housing. The drive end is driven by a servo motor. A reflector snapped onto the front end of the rear housing; the reflector is concave, with the lens exposed at its center; and A transparent lampshade is installed at the front of the rear housing.
[0007] Furthermore, the pivot extends to both ends of the lens and is housed within a groove in the rear housing, with limits set by screws and pressure plates. This pivot installation method ensures the stability and accuracy of the lens during rotation, preventing irradiation effects caused by shaking.
[0008] Furthermore, the lens is convex outwards and horizontally aligned vertically. The convex curvature helps diffuse light, while the horizontal alignment ensures a basic direction of illumination, providing a good foundation for dynamic adjustments.
[0009] Furthermore, the lens is made of PC. PC material has good light transmittance, impact resistance, and high temperature resistance, which can meet the usage requirements of fog lights in various harsh environments.
[0010] Furthermore, a waterproof and breathable cap is installed on the rear housing. The waterproof and breathable cap can prevent moisture from entering the interior of the rear housing, while ensuring air circulation between the inside of the housing and the outside, thus preventing the performance of various components from being affected by excessively high internal temperatures.
[0011] Compared with the prior art, the present invention can achieve the following technical effects: 1) A servo motor drives an adjusting screw, which meshes with the rack and pinion on the lens adjustment pin, causing the lens to rotate around a pivot, thus dynamically adjusting the fog light's illumination angle. Drivers can flexibly adjust the fog light's illumination angle according to actual fog density, road gradient, and other conditions, improving driving safety.
[0012] 2) The heat dissipation fins on the heat sink are exposed on the back side of the housing, allowing them to fully contact the outside air and quickly dissipate the heat generated by the LED light board during operation, ensuring the lifespan and operational stability of the LED beads.
[0013] 3) The lens is mounted on the rear housing via a pivot, which ensures the stability of the lens rotation; the connection methods between the components (such as screw fixing, snap-fit connection, etc.) also ensure the robustness of the entire fog light structure.
[0014] 4) The lens is made of PC material, which has good performance; the waterproof and breathable cap installed on the rear shell effectively protects the internal components, improves the durability of the fog light, and enables it to adapt to various harsh environmental conditions.
[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the above-mentioned technical effects at the same time. Attached Figure Description

[0019] The following will describe in detail the implementation of this utility model with reference to the accompanying drawings and embodiments, so that the implementation of this utility model can be fully understood and carried out based on how technical means are used to solve technical problems and achieve technical effects.
[0020] Please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram of a dynamically adjustable fog light according to an embodiment of the present invention; Figure 2 This is a schematic diagram of the internal structure of the dynamically adjustable fog light according to an embodiment of this utility model; Figure 3 This is a rear view of a dynamically adjustable fog light according to an embodiment of the present invention.
[0021] As shown in the figure, a dynamically adjustable fog light includes a rear housing 10. A heat sink 20 is fixed inside the rear housing 10 by screws. The heat dissipation fins 21 of the heat sink 20 are exposed on the rear side of the rear housing 10 to enhance heat dissipation. The heat sink 20 is sealed and fixed around its perimeter by a sealing ring. An LED light panel 30 is installed on the front side of the heat sink 20. The LED light panel 30 is equipped with multiple fog light beads to provide a light source for the fog light.
[0022] The lens 50 is mounted to the rear housing 10 via a pivot 40, and covers the fog light bulb. The pivot 40 extends to both ends of the lens 50 and is accommodated in a groove in the rear housing 10. Screws and a pressure plate 90 are used to limit its movement, ensuring that the lens 50 can rotate stably around the pivot 40. An adjustment pin 60 is provided on one side of the lens 50 to guide its rearward movement; the adjustment pin 60 has a toothed portion 61.
[0023] The adjusting screw 70 is mounted to the rear housing 10 via bearings and engages with the rack and pinion section 61. The adjusting screw 70 has a drive end 71 exposed above the rear housing 10, which is driven by a servo motor. When the servo motor is working, it drives the adjusting screw 70 to rotate. Through engagement with the rack and pinion section 61, the adjusting screw 70 drives the lens 50 to rotate around the pivot 40, thereby adjusting the fog light's illumination angle.
[0024] A reflector 80 is snapped onto the front end of the rear housing 10. The reflector 80 is concave, with the center of the lens 50 exposed. The reflector 80 can reflect the light emitted by the fog light bulb, enhancing the illumination effect of the fog light. A transparent lamp cover is also installed at the front end of the rear housing 10. The transparent lamp cover can protect the internal components without affecting the light emission.
[0025] In addition, a waterproof and breathable cap 91 is installed on the rear housing 10 to ensure that the interior of the rear housing 10 is waterproof and breathable. The lens 50 is made of PC material and has good performance.
[0026] In summary, this utility model fog light can dynamically adjust the illumination angle, has good heat dissipation, a stable structure, and strong durability, thus improving driving safety.
