Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, and in particular to a dual-color dual-beam inner lamp cover structure for automotive lighting. Background Technology

[0002] Vehicle headlights need to simultaneously provide illumination and ensure oncoming traffic safety, thus requiring separate low beam and high beam headlights. Existing headlights generally use an inner lamp cover, combined with a functional partition panel and panel bracket to achieve integrated dual-beam functionality. However, this structure suffers from problems such as complex design, large space occupation, difficult assembly, and unstable light efficiency.

[0003] Existing patents use a solution of partial aluminum plating of the structure as a dual-beam baffle to solve technical problems such as space occupation and complicated installation. However, the partial aluminum plating method has the risk of external sunlight reflection and heat focusing, which makes the headlight less reliable and the aluminum plating process is costly. Utility Model Content

[0004] The technical problem to be solved by this utility model is: in order to solve the problem of high cost and low reliability of existing integrated bi-xenon headlights, this utility model provides a bi-color high and low beam inner lamp cover structure for headlights, which uses a heat-resistant partition plate as a bi-xenon baffle, thereby reducing costs while ensuring product consistency and reliability.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a dual-color high and low beam inner lamp cover structure for vehicle lights, including a low beam part and a high beam part:

[0006] The low beam section includes a low beam incident surface for receiving low beam light and a low beam exiting surface for emitting low beam light; the high beam section includes a high beam incident surface for receiving high beam light and a high beam exiting surface for emitting high beam light.

[0007] The high beam section is equipped with a partition plate, the upper surface of which blocks the low beam rays and forms a low beam cutoff line. Thus, the partition plate acts as a dual-beam baffle, replacing the existing aluminum plating process; this reduces costs while also lowering the risk of heat from external sunlight reflection and focusing, reducing the impact of heat on luminous flux, and thereby improving the reliability of the headlights.

[0008] Furthermore, the low beam section, high beam section, and partition plate are manufactured using a two-color integrated injection molding process. The low beam section and high beam section are transparent components, while the partition plate is an opaque component with a thickness of 1.5-2.5mm. The partition plate is made of gray high-temperature resistant PC material, while the low beam section and high beam section are made of PMMA or PC material. Thus, the two-color integrated injection molding process aligns with the concept of green environmental protection, utilizing lower-quality core materials to reduce costs. Simultaneously, the outer layer or core material can be made of high-temperature resistant materials to enhance product performance, avoiding the need for additional processes or structures to address the impact of temperature on luminous flux. This optimizes the overall structure and achieves a compact size.

[0009] Furthermore, the side of the partition away from the high beam section is provided with a dark leather texture of model K29; where K29 is a commonly used model in the industry. The dark leather texture of the K29 partition not only ensures a good appearance, but also helps to improve the uniformity of the lighting effect, ensure uniform lighting of the road ahead, and avoid blind spots.

[0010] Furthermore, the high beam section also includes a high beam beam leveling plate disposed on the high beam incident surface and the high beam exit surface, and the partition plate is disposed on the upper surface of the high beam beam leveling plate and disposed along the propagation direction of the low beam.

[0011] Furthermore, the near beam emission surface is provided with a free-form surface; thus, while achieving a uniform distribution of near beam projection, the required width in the design state is guaranteed, with a width deviation greater than or equal to 40°-50°.

[0012] Furthermore, the near beam emitting surface is provided with striped patterns; thus, while achieving uniform distribution of near beam projection, the required width in the design state is guaranteed, with a width deviation greater than or equal to 40°-50°.

[0013] Furthermore, the high-beam homogenizer is made of a homogenizing material; thus, the incident high-beam light rays achieve uniform diffusion after passing through the high-beam homogenizer made of homogenizing material.

[0014] Furthermore, the high beam emitting surface is provided with a free-form surface or striped pattern; thereby, the high beam emitting surface will scatter the light passing through the high beam uniform sheet a second time, ensuring that the high beam reaches the set effective illumination range, thereby eliminating edge dark areas; its width deviation is ±20°, and its depth deviation is ±5°.

[0015] Furthermore, a concentrator corresponding to the number of near light sources is provided at the near light incident surface; thereby achieving the effect of near light guiding and concentrating.

[0016] Furthermore, a second concentrator corresponding to the number of high beam light sources is provided at the high beam light-incident surface; thereby achieving the effect of high beam light guiding and concentrating.

[0017] The beneficial effects of this utility model are that the dual-color high and low beam inner lamp cover structure of the vehicle lamp of this utility model is provided with an opaque partition plate. The gray high temperature resistant PC material partition plate serves as a dual beam baffle, replacing the existing aluminum plating process. While reducing costs, it also reduces the heat risk of external sunlight reflection and focusing, reduces the impact of heat on luminous flux, and thus improves the reliability of the vehicle lamp.

[0018] This utility model's dual-color dual-beam inner lamp cover structure for automotive lights utilizes a dual-color integrated injection molding process for the low beam section, high beam section, and dividing plate. This optimizes the structural composition of the original dual-beam module solution, providing a smaller dual-beam concentrator structure. It improves assembly convenience while adapting to the space constraints of modern automotive light designs. Furthermore, the dual-color integrated injection molding conforms to the concept of green environmental protection, using lower-quality core materials to reduce costs. At the same time, the skin or core materials use high-temperature resistant materials to increase product performance and improve the reliability of the device.

[0019] The dual-color high and low beam inner lamp cover structure for vehicle lights of this utility model solves the problem that the use of a concentrator will reflect a bowl shape on the surface of the lamp cover by using a high beam light-diffusing sheet made of light-diffusing material and a partition plate with K29 dark leather texture. This optimizes the lighting effect and improves the lighting performance and illumination uniformity of the dual beam module. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0026] like Figures 1-3The image shown is the preferred embodiment of this utility model, a dual-color high / low beam inner lamp cover structure for automotive lights, as described in the reference. Figure 1 , Figure 2 The light fixture includes an inner lampshade, which comprises a low beam section 11, a high beam section 12, and a partition plate 13. The low beam section 11 and the high beam section 12 are made of PMMA or PC material, and the partition plate 13 is made of gray high-temperature resistant PC material. The low beam section 11 includes a low beam incident surface and a low beam emitting surface 112. The high beam section 12 includes a high beam incident surface, a high beam diffuser 123, and a high beam emitting surface 122. The high beam diffuser 123 is disposed between the high beam incident surface and the high beam emitting surface 122. The length of the high beam diffuser 123 is greater than the distance between the light surface and the low beam emitting surface 112. A condenser 111 corresponding to the number of low beam light sources is disposed at the end of the low beam incident surface away from the low beam emitting surface 112. A condenser 2 121 corresponding to the number of high beam light sources is disposed at the end of the high beam incident surface away from the high beam diffuser 123.

[0027] The partition plate 13 is disposed on the upper surface of the high beam diffuser 123 and is disposed along the propagation direction of the low beam light; thus, the partition plate 13 acts as a dual beam baffle, replacing the existing aluminum plating process; while reducing costs, it reduces the heat risk of external sunlight reflection and focusing, reduces the impact of heat on luminous flux, and thus improves the reliability of the vehicle lights.

[0028] Among them, the low beam section 11, the high beam section 12 and the partition plate 13 are made of two-color one-piece injection molding. The partition plate 13 is an opaque component and the thickness of the partition plate 13 is 1.5-2.5mm. Therefore, the two-color injection molded partition plate 13 conforms to the concept of green environmental protection, uses a lower quality core material to reduce costs, and uses high temperature resistant materials for the skin material or core material to increase product performance.

[0029] Reference Figure 2 The partition plate 13 is provided with a dark leather texture 131 of model K29 on the side away from the high beam part 12; K29 is a commonly used model in the industry. The partition plate 13 with dark leather texture 131 of K29 not only ensures a good appearance, but also helps to improve the uniformity of the lighting effect, ensure uniform lighting of the road ahead, and avoid blind spots.

[0030] Reference Figure 3 The low beam output surface 112 is provided with a free-form surface 21 or a striped pattern 22; thus, while achieving a uniform distribution of low beam projection, the required width of the design state is guaranteed, and the width deviation is greater than or equal to 40°-50°.

[0031] The high-beam homogenizer 123 is made of homogenizing material, and the high-beam emitting surface 122 is provided with a free-form surface 21 or striped pattern 22. Thus, the incident high-beam light is uniformly diffused after passing through the homogenizing material in the high-beam homogenizer 123. The high-beam emitting surface 122 performs secondary scattering of the light passing through the high-beam homogenizer 123, ensuring that the high beam reaches the set effective illumination range, thereby eliminating edge dark areas. Its width deviation is ±20°, and its depth deviation is ±5°. Simultaneously, it solves the problem of a concentrator reflecting a bowl shape on the lampshade surface, optimizing the lighting effect and improving the lighting performance and illumination uniformity of the dual-beam module.

[0032] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
