Light-transmitting structure with special stone skin effect and manufacturing method thereof

Abstract

The invention discloses a light-transmitting structure with special stone skin effect and a manufacturing method thereof. The light-transmitting structure with the special stone skin effect comprises a stone skin layer, a light-transmitting soft rubber layer and a substrate layer which are sequentially fixed and compounded from top to bottom, and further comprises a backlight module installed on the back face of the substrate layer and an MCU main board electrically connected with the backlight module. A planar light source formed by the backlight module can be finally transmitted to the surface of the stone skin layer through a light-transmitting area on the substrate layer and the light-transmitting soft rubber layer to form a light-emitting area. The manufacturing method comprises the steps that the substrate layer with the light-transmitting area is manufactured firstly; then the surface of the substrate layer is coated with a transparent colloidal polymer; cut stone skin is attached to the surface of the transparent colloidal polymer, and standing for drying is conducted; and finally, the backlight module is installed on the other side of the substrate layer, and the backlight module is electrically connected with a control circuit on the MCU mainboard through a circuit. According to the invention, the surface of stone skin is provided with atmosphere lamps with different light-emitting patterns, so automobile stone-skin trim is attractive in appearance and soft and comfortable in hand feeling.

Description

technical field [0001] The invention relates to the field of automobile interior decoration, in particular to a light-transmitting structure with special effect of stone skin. Background technique [0002] At present, ambient lights are widely used in automobile interiors. They are divided into lights that are formed on the interior surface by embedding, and stone skin interiors are more and more commonly used. Embedded atmosphere lights appear on stone skin interiors. The abruptness reduces the overall aesthetics of the interior of the stone skin, and the stone skin is a material with poor light transmission performance. At the same time, its texture is hard and easy to crack, so it is difficult to directly use it to form a light-transmitting shell When the light source is used, it is also prone to cracking and damage at the edge of the embedded hole. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a sto...
