Description
Technical Field
[0001] This utility model relates to the field of automotive lighting technology, specifically to a lens-type automotive lighting focusing structure. Background Technology
[0002] Automotive lighting systems are crucial for nighttime driving safety, and their technological iterations keep pace with the development of the automotive industry. Lens-type headlights, with their excellent light focusing and precise light control capabilities, have become an important technological direction for modern automotive lighting. Early car headlights used a simple reflector bowl design, which focused the light through reflection. However, the light distribution was uneven and the edges of the light spot were blurry, resulting in blind spots and glare. Later, a single lens focusing solution was used, which improved the light concentration but could not effectively solve the lighting needs under different road conditions. With the advancement of technology, halogen lamps, xenon lamps and LED lamps have gradually become the mainstream headlight sources. Although they have significantly improved in terms of luminous efficiency and lifespan, they still have limitations in terms of light focusing and lighting effect optimization. Traditional vehicle headlights typically use a single parabolic reflector or a simple lens combination for focusing light. This results in low light collection efficiency and a large amount of light being scattered into the surrounding environment. This not only wastes light energy but also easily causes glare interference to other road users, reducing the safety of driving at night. Therefore, a lens-type automotive headlight focusing structure is proposed to address the above problems. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0016] Please see Figures 1-6 This utility model provides a technical solution: A lens-type automotive headlight focusing structure includes a mounting plate 1, a lamp source body 2 disposed on the outer side of the mounting plate 1, and a focusing mechanism 3 mounted on the outer side of the lamp source body 2. The focusing mechanism 3 includes a light tube 31, a connecting plate 32 is fixedly connected to the outside of the light tube 31, a conical reflector 33 is fixedly connected to the outside of the connecting plate 32, and a light outlet hole 34 is opened inside the conical reflector 33.
[0017] It should be noted that: the light tube 31 is fixedly connected to the outside of the light source body 2, and the conical reflector 33 is fixedly connected to the end of the light tube 31 away from the light source body 2 through the connecting plate 32. The conical reflector 33 and the light tube 31 are in a connected state, and the center positions of the two are on the same plane.
[0018] Furthermore, the combination of the conical reflector 33 and the lamp tube 31 is based on the parabolic reflection optical principle. After the light enters the conical reflector 33 from the lamp tube 31, its inner wall follows the law of light reflection, reflecting and converging the diverging light towards the central axis.
[0019] Specifically: Compared to the traditional single reflector design of car lights, this structure can convert more scattered light into parallel or near-parallel beams, which are emitted through the light outlet 34. Actual test data shows that the light concentration is increased by about 30%-40%, the effective lighting distance is extended by 15%-20%, and the nighttime driving lighting effect is significantly enhanced.
[0020] As a further implementation of this solution, a range adjustment mechanism 4 is provided on the outside of the light output hole 34. The range adjustment mechanism 4 includes a connecting plate 41. An electric telescopic rod 42 is fixedly connected to the top of the connecting plate 41. A lifting rod 43 is fixedly connected to the output end of the electric telescopic rod 42. A shielding plate 44 is fixedly connected to the bottom of the lifting rod 43. A limiting rod 45 is fixedly connected to the outside of the lifting rod 43. A slider 46 is fixedly connected to the end of the limiting rod 45 away from the lifting rod 43. A moving groove 47 is provided in the side wall of the connecting plate 32.
[0021] It should be noted that: the connecting plate 41 is fixedly connected to the outside of the connecting plate 32, the bottom of the lifting rod 43 is movably connected to the bottom of the connecting plate 41, the shielding plate 44 is slidably connected to the outside of the light outlet hole 34 through the lifting rod 43, and the area of the shielding plate 44 is the same as the area of the light outlet hole 34. The slider 46 is slidably connected to the inside of the moving groove 47, and the shielding plate 44 is tightly attached to the outside of the light outlet hole 34.
[0022] Furthermore, the limiting rod 45 fixedly connected to the outside of the lifting rod 43 has a slider 46 at the end away from the lifting rod 43 that is slidably connected to the inside of the moving groove 47 opened on the side wall of the connecting plate 32. This structure plays a limiting and guiding role. During the process of the lifting rod 43 driving the blocking plate 44 to move, the slider 46 slides along the moving groove 47 to ensure that the lifting rod 43 can only move stably in the vertical direction, preventing the lifting rod 43 from deviating or shaking during the movement, and ensuring that the blocking plate 44 can accurately block or release the light outlet 34, thereby achieving precise adjustment of the lighting range.
[0023] Specifically, the range adjustment mechanism 4 precisely controls the raising and lowering of the shielding plate 44 through the electric telescopic rod 42, realizing stepless adjustment of the lighting range. Compared with the traditional mechanical knob adjustment, this design improves the response speed by more than 60%, and can be linked with the vehicle's intelligent driving assistance system. For example, when the vehicle enters the tunnel, the sensor triggers a signal to shorten the electric telescopic rod 42, and the shielding plate 44 covers the light-emitting hole 34, reducing the lighting range and avoiding glare caused by light reflection on the tunnel wall. After exiting the tunnel, the system automatically adjusts to increase the lighting range, improving driving safety and comfort.
[0024] Workflow: Mounting plate 1 serves as a basic component, providing stable mounting support for lamp source body 2. After lamp source body 2 is powered on, it generates light, which enters focusing mechanism 3. The lamp tube 31 in focusing mechanism 3 is fixed to the outside of lamp source body 2, becoming a channel for light transmission, allowing light to be smoothly introduced from lamp source body 2 into subsequent structures. Conical reflector cup 33 is fixed to the end of lamp tube 31 away from lamp source body 2 via connecting plate 32, and the conical reflector cup 33 and lamp tube 31 are in a connected state, with their centers on the same plane. This precise structural design creates favorable conditions for light convergence. When light enters conical reflector cup 33 from lamp tube 31, due to the special shape of conical reflector cup 33, its inner wall reflects the light towards the center. The light is continuously reflected inside conical reflector cup 33, gradually converging at light outlet hole 34, and finally emitted through light outlet hole 34 in a relatively concentrated beam form, achieving initial convergence of light, improving the concentration and brightness of light, and enhancing the lighting effect of vehicle lights; A range adjustment mechanism 4 is installed outside the light-emitting hole 34, mainly used to adjust the illumination range of the vehicle headlight. A connecting plate 41 is fixedly connected to the outside of the connecting plate 32, providing an installation base for the electric telescopic rod 42. The electric telescopic rod 42 serves as a power source, and its output end is connected to the lifting rod 43. When the illumination range needs to be adjusted, the electric telescopic rod 42 is activated, and the lifting rod 43 moves up and down through the telescopic movement. A shielding plate 44 is fixedly connected to the bottom of the lifting rod 43. Its area is the same as that of the light-emitting hole 34, and it is slidably connected to the outside of the light-emitting hole 34 through the lifting rod 43. When the electric telescopic rod 42 extends, the lifting rod 43 drives the shielding plate 44 to move downward. The shielding plate 44 gradually moves away from the light-emitting hole 34, and at this time, the light from the light-emitting hole 34 shines... With an increased range, the headlights illuminate a wider area, making them suitable for use in scenarios with complex road conditions and high visibility requirements, such as when driving at night on rural roads or mountain roads. This allows the driver to see the road conditions in a wider area. When the electric telescopic pole 42 is shortened, the lifting pole 43 moves the shielding plate 44 upward. The shielding plate 44 gradually approaches and covers the light-emitting hole 34, blocking the light emitted from the light-emitting hole 34. This reduces the range of light emission, narrows the illumination range of the headlights, and makes the light more concentrated. This is suitable for use in scenarios with high requirements for light concentration, such as urban roads. When driving on roads with streetlights in the city, the concentrated light can avoid glare interference to other vehicles and pedestrians, while also illuminating the road conditions at close range more clearly.
