Abstract: The combination instrument is an important part of the interior of the car, in the process of driving, it provides all kinds of information and data for the driver. With the development of science and technology, drivers have higher and higher requirements for the structural modeling of the combination instrument, and hope to provide high-tech display effect and more comfortable driving experience. This paper studies the structural design of the atmosphere lamp of various automobile combination instruments, through the analysis of the structural design and development of transparent upper cover, front frame, light guide plate, black film, RGB-LED and so on, a hidden atmosphere lamp structure of combination instruments is designed, which solves the problems of single color, uneven backlight and high cost of the atmosphere lamp of automobile combination instruments. The display effect of the atmosphere light and the driving experience of the automobile combination instrument is improved. At the same time, it provides an effective reference for the structural design of automobile combination instrument, so as to achieve a fashionable and high-end automobile interior display effect.
