Description

Technical Field

[0001] The present invention relates to the technical field of automobile parts, and in particular to a speaker cover decorative structure, a vehicle door and a vehicle. Background Art

[0002] As consumers' demands for personalized, humanized and intelligent car design continue to increase, car interiors have also become people's independent private spaces, which has also led to people's increasing requirements for interior environment atmosphere and interior comfort. The various forms of realizing ambient lighting effects are also an important means to enhance the sense of interior grade.

[0003] Traditional ambient lights generally have lamp shells that are directly exposed on the interior surface or are displayed through IML and other film-coated parts (In Molding Label, Chinese name: in-mold insert injection molding, the process has the following very notable features: the surface is a hardened transparent film, the middle is a printed pattern layer, and the back is a plastic layer. Because the ink is sandwiched in the middle, the product can prevent the surface from being scratched and resistant to friction, and can maintain bright colors for a long time and not easy to fade). The light-transmitting medium of the light-guiding strip light source is directly exposed on the interior surface, and the color changes of the ambient light are displayed through the dynamic changes of the color of the ambient light guide. This structural form realizes the effect of line light source ambient light, which makes the traditional ambient light single in form, poor in appearance, hard in surface, low in comfort, and poor in grade. Summary of the Invention

[0004] To solve the above problems, the present invention proposes a speaker cover decoration structure, which abandons the traditional surface light source and IML decorative panel structure, hides the atmosphere light behind the electroplating decorative panel, and ensures the beauty of the shape. When the light is turned off, the atmosphere light is perfectly hidden in the electroplating decorative panel, and the door panel surface only presents a landscape effect; when the light is turned on, the atmosphere light appears and blends with the original landscape effect; this form of expression can create a unique atmosphere of technology and luxury, and is an important decoration for the interior of the car, especially at night, to show differences and enhance the texture of the interior; it also has a touch function. When a person touches the surface of the interior part, the capacitance of the touch flexible circuit board will change, and the touch signal will be transmitted to the PCB control circuit board; the PCB control circuit board makes corresponding actuation control according to the program; by touching the surface of the interior part, the atmosphere light can be dimmed and changed in color to create the desired atmosphere and become more technological.
