Description

Technical Field

[0001] The invention belongs to the technical field of automobile lamps, and in particular relates to an interior mirror with uniform three-dimensional luminescence, a lamp and a manufacturing method of the interior mirror. Background Art

[0002] With the change of national policies and the rise of new car brands, the competition in China's auto market has become increasingly fierce. As the most important selling point of automobile products, the appearance of automobiles has naturally become a key part that attracts much attention. As an important part of the appearance, the car lights have become the research and development focus of various OEMs to expand the market share with various novel car light shapes and novel lighting dynamic effects.

[0003] The three-dimensional and layered headlight shape has always been the goal pursued by styling designers. However, the three-dimensional and layered shape has brought huge challenges to molds, structures, optics, and processes due to a series of problems such as high manufacturing difficulty, difficulty in blocking light, and difficulty in achieving uniformity at all angles. The key issue that major domestic automotive lighting manufacturers need to solve in the process of new product development is how to meet the styling requirements to the greatest extent while ensuring the feasibility of product mass production, thereby improving their own competitiveness.

[0004] As an important part of the headlight, the interior mirror adopts a single-color injection molding combined with a surface treatment solution, which cannot achieve the three-dimensional linear features required by the modeling. The reason is that the step features contained in the three-dimensional linear features 100 cause the problem of uneven wall thickness and shrinkage marks under the single-color injection molding process, which is unavoidable. Figure 1 As shown; limited by the one-sidedness of the surface treatment process, it is impossible to ensure that the inner side of the peripheral assembly structure is opaque, resulting in light leakage around the periphery; in addition, the peripheral assembly structure is easily damaged during the assembly process, causing the surface layer to fall off, further increasing the risk of light leakage; for the modeling requirements, the light-transmitting surface with a single wall thickness has linear characteristics. Due to the limitations of its thickness and width, it is difficult to fill the molten resin, and the injection molding process cannot be used. A short-shot area 200 will be formed at the turning point, such as Figure 2 As shown in the figure; the laser engraving solution after painting is adopted. The painted surface 300 is easily scratched during transportation and assembly, causing light leakage. The painting cannot guarantee the thickness of the paint, causing light leakage. Figure 3 As shown, this solution has low efficiency, high cost and is not easy to meet environmental protection requirements. Summary of the invention

[0005] In order to solve the problems in the prior art of difficulty in designing a three-dimensional and layered headlight, high manufacturing difficulty, difficulty in blocking light, and difficulty in achieving uniformity at all angles, the present invention provides an interior mirror and a headlight with uniform three-dimensional luminescence, and a method for manufacturing the interior mirror.
