Automotive interior trim atmosphere lamp assembly and manufacturing method thereof

Abstract

The invention discloses an automotive interior trim atmosphere lamp assembly and a manufacturing method thereof, and relates to the technical field of automotive interior trims. The atmosphere lamp assembly comprises: a light-transmitting surface layer, wherein one side of the light-transmitting surface layer is carved off to form a light-transmitting pattern; a foaming layer arranged on one side,provided with the light-transmitting pattern, of the light-transmitting surface layer; a light scattering framework flatly bonded with one side, far away from the light-transmitting surface layer, ofthe foaming layer through a hot melt adhesive layer and used for uniformly scattering received light rays; a lamp shell provided with a containing cavity, wherein the lamp shell is buckled to the side, away from the foaming layer, of the light scattering framework, and a light reflecting layer used for reflecting light is arranged on the inner wall of the containing cavity; and a lamp body arranged in the containing cavity. According to the automotive interior trim atmosphere lamp assembly and the manufacturing method thereof, the texture effect of soft touch of the automotive interior trim atmosphere lamp assembly can be achieved, and when the atmosphere lamp is lightened, the light-emitting effect of the atmosphere lamp can be guaranteed, and customer requirements are met; and the overall brightness of the atmosphere lamp and the light transmittance uniformity of the atmosphere lamp assembly can be further improved.

Description

technical field [0001] The present application relates to the technical field of automobile interior decoration, in particular to an automobile interior atmosphere lamp assembly and a manufacturing method thereof. Background technique [0002] With the continuous improvement of performance requirements in all aspects of automobile products and the promotion of automobile smart cockpit functions, user technology experience has been significantly improved. Major OEMs and parts suppliers are also paying more and more attention to smart cockpits. Smart atmosphere lights in automobile interiors The scope of application of technology is getting wider and wider. [0003] With the development and application of light-transmitting skin, a new material for smart surface interiors, new requirements are put forward for ambient lights, that is, the effect of ambient lights can be achieved at night, and the surface of ambient lights can achieve a soft-touch texture effect during the day o...

AI Technical Summary

Problems solved by technology

One is that the ambient light transmits light through the gaps formed between the various components of the interior, but due to the limitations of the multi-layer overlapping of parts and the light transmittance of the material itself, the light transmittance of the ambient light assembly is poor, and the pattern display is not good. Clear; the other is to transmit light through a light-transmitting single-layer hard plastic product, but it cannot meet the current requirements for ambient lights

[0005] In the prior art, there are ambient lights that use a method different from the above, that is, by adding a pattern layer to the skin of the ambient light to achieve a soft surface touch, although the appearance of the ambient light when it is not lit can be achieved, but due to the skin The pattern layer is generally glued on the outside of the ambient light. When glue is used for pasting, the uneven thickness of the glue will lead to inconsistent light transmittance of the light source, and even glue seepage will cause the light transmittance of the ambient light shell to change, resulting in the failure of the lighting state. The light transmission effect of the ambient light is still poor

In order to improve the light transmittance, generally only by increasing the brightness of the light source, but under high power conditions, the heat generated by the light source will easily lead to an increase in temperature, exceeding the normal operating conditions
