Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to an ultra-thin door sill light. Background Technology

[0002] In recent years, more and more car interior lights have appeared in the public eye, enhancing the aesthetics of the car interior while being practical and improving the driving experience. However, existing car door sill lights take up a lot of space, causing wear and tear on the bottom of the door due to frequent opening and closing. Utility Model Content

[0003] To address the technical problem of wear and tear on the bottom of car doors when opening and closing them, this invention provides an ultra-thin door sill light that reduces space usage.

[0004] An ultra-thin door sill light includes a housing with a groove formed on the inner side, which is close to the vehicle body. The inner side of the housing is directly installed on the vehicle body. A light assembly is embedded in the groove. The light assembly includes an inner baffle and an outer guard plate. After the light assembly is embedded, the outer guard plate and the outer side of the housing are on the same plane. An optical component and a circuit board are disposed between the inner baffle and the outer guard plate. The optical component is used to uniformly illuminate the light emitted by the light source on the circuit board. A light groove is formed on the outer guard plate to allow the emitted light to leak out.

[0005] Technical effects:

[0006] The new overall structure allows the door sill light assembly to reach a thickness of 6mm, with the inner baffle being 0.5mm thick. Installed at the door sill below the car door, it not only reduces the space occupied, but the outer protective plate is made of sturdy and durable materials such as aluminum, further preventing wear and tear on the bottom of the door caused by frequent opening and closing. When the door is opened, the door sill light automatically turns on, providing illumination for passengers getting in and out of the car. Attached Figure Description

[0011] To make the objectives, technical solutions, and technical effects of this utility model clearer, the specific embodiments of this application will be described in further detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely for explaining this application and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

[0012] like Figures 1-3 As shown, this embodiment provides an ultra-thin door sill light, including a housing 4 with a groove formed on its inner side, with the inner side close to the vehicle body. The inner side of the housing 4 is directly installed with the vehicle body. A light assembly is embedded in the groove. The light assembly includes an inner baffle 1 and an outer protective plate 2. After the light assembly is embedded, the outer protective plate 2 and the outer side of the housing 4 are on the same plane. An optical component and a circuit board 3 are disposed between the inner baffle and the outer protective plate. The optical component is used to uniformly illuminate the light emitted by the light source on the circuit board 3. A light groove 201 is formed on the outer protective plate 2 to allow the emitted light to leak out.

[0013] Furthermore, the optical component is ultrasonically welded to the inner baffle 1. The optical component is provided with a reflective film 5, a light guide plate 6, and a light distribution lens 7 in sequence away from the vehicle body. The circuit board 3 is installed at one end of the light guide plate 6. The light emitted by the light source enters the edge of the light guide plate 6. The light guide plate 6 can guide the light to overflow evenly. At the same time, the reflective film 5 can recover the light leaking from the back and reflect it back to the light guide plate 6. The light distribution lens 7 can diffuse and soften the emitted light to achieve uniform illumination.

[0014] Furthermore, the circuit board is connected to the input harness 8, which enables the sill light to be connected to the power supply.

[0015] Furthermore, the housing 4 is inverted L-shaped, horizontally fixed to the vehicle body via at least two integrally formed limiting posts 9, and vertically fixed to the vehicle body with 3M double-sided tape, making installation more convenient. The housing 4 provides shelter for the light assembly and other components inside the recess, preventing exposure of the internal components of the door sill light, protecting them from external impacts, avoiding safety issues caused by exposed internal components, and improving aesthetics. The material is, for example, one or a combination of polycarbonate, polypropylene, or acrylic.

[0016] In one possible implementation, the internal reflective film 5, light guide plate 6, and light distribution lens 7 of the optical component are bonded together in pairs. The light distribution lens 7 is fixed to the outer protective plate 2 with light-shielding double-sided adhesive, and the inner protective plate 1 is fixed to the housing 4 with double-sided adhesive primer. Some gaps are further fixed with sealant. Since most components of the threshold light are fixed by adhesive bonding, large-scale modifications and damage to the installation location are not required. This not only simplifies the installation process but also improves the stability and durability of the overall structure. Furthermore, the adhesive bonding method effectively reduces maintenance costs, allowing the threshold light to maintain good lighting performance in various environments.

[0017] The embodiments of this utility model disclosed above are merely illustrative of the present utility model. The embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Obviously, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
