Description

Starlight dot-matrix type luminous decoration panel structure

Technical Field

The utility model belongs to automotive interior subassembly field relates to a luminous decorative panel structure of starlight dot matrix.

Background

In order to improve the competitiveness of automobiles and meet the increasing demands of consumers on luxury, comfort and science of interior decorations, the design of interior light has been more and more emphasized by various manufacturers. In recent years, various forms of atmosphere lamps such as a rainy spring bamboo shoot have become more common, and the use of atmosphere lamps has also become more common. Most atmosphere lamps in the market realize the luminous effects of different colors and different shapes through LED luminous dot matrixes or light guide pipes. The same type of panel luminous type atmosphere lamps in the market are realized by an INS in-mold film coating process, the core of the process is that a required modeling pattern is printed on a light-transmitting membrane, and then the membrane and a transparent framework are molded into a whole by an in-mold film embedding process. The printing ink can also be realized by a silk-screen printing process, namely, the uneven modeling characteristics are engraved on the copper plate, the printing ink is attached to the concave pits, and the printing ink remained on the copper plate is adhered by a special rubber head and then is transferred to the surface of the part. The existing process has the defects that the surface of a model is required to be smooth, the radian cannot be too large, in addition, the circular characteristic with a small diameter similar to a starlight lattice cannot be printed, in addition, a transparent base material and a transparent membrane are required to be selected in the existing process, the cost is higher, the membrane development period is long, the process limitation conditions are more, and the modeling effect cannot be flexibly changed after the membrane is developed.

Disclosure of Invention

The utility model discloses an overcome the above-mentioned problem that prior art exists, provide a luminous decorative panel structure of starlight dot matrix.

The utility model discloses an adopt following technical scheme to realize:

a starlight dot-matrix type luminous decoration panel structure comprises a panel and a luminous assembly positioned below the panel, and is characterized in that the panel is made of a high-light-transmittance light-transmitting material, the lower surface of the panel is sprayed with black paint, the black paint is carved into a multi-point light-transmitting starlight dot matrix shape through a laser process, namely the black paint is etched and removed through the laser process at the position of a starlight point needing to be transmitted, the luminous assembly comprises a wiring harness, a light guide plate, a first LED lamp set, a second LED lamp set, a reflecting plate and a framework, the first LED lamp set is fixed at one end of the light guide plate, the second LED lamp set is fixed at the other end of the light guide plate, the reflecting plate is fixed below the light guide plate, the framework is positioned below the reflecting plate, the wiring harness is connected with the first LED lamp set and the second LED lamp set, the framework is welded with the panel, and further fixes the light guide plate, the first LED lamp set, the, the wire harness extends out of the through hole formed in the framework.

The further technical scheme comprises the following steps:

the thickness of the panel is not less than 3mm, and the edge of the panel is provided with a flanging which is turned downwards so as to ensure the strength of the panel.

The lower surface outward flange of panel is provided with a plurality of welding muscle that are used for with the skeleton welded, is provided with the bellied soldering lug with the welding muscle welded of panel on the skeleton.

The panel is made of a high light transmittance PC material.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses a back at the printing opacity material of high luminousness (like the PC material of high luminousness) sprays paint, then the surface laser radium carving that sprays paint goes out the starlight dot matrix pattern that wants, and then realize nimble changeable printing opacity pattern effect, in addition, the light that spare part lower surface sees through is through the refraction that is not less than 3mm printing opacity panel, and then produces profound, dim luminous effect, its advantage is low cost, the technology degree of difficulty is little, the rejection rate is low, the molding scheme can change easily through switching radium carving procedure.
