Embodiment Construction

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0018] At present, there are technical problems of high cost, poor light isolation effect and uneven lighting in the use of white backlight reflectors.

[0019] See figure 2 , in order to solve the above technical problems, this embodiment provides a structure of instrument backlight reflector, including cover plate 6, plastic panel 8 and PCBA9 arranged from top to bottom. A cavity for accommodating the display screen 7 is formed on the plastic panel 8 . ...

Abstract

The invention relates to the technical field of instrument reflecting parts, in particular to an instrument backlight reflecting part structure. The structure comprises a cover plate, a plastic panel and a PCBA which are arranged from top to bottom; a cavity for accommodating a display screen is formed in the plastic panel; a character display area is formed on the cover plate; an LED lamp is arranged on the PCBA; and a lampshade is formed on the plastic panel, the bottom of the lampshade is connected with the LED lamp, and an opening of the lampshade faces the character display area. The invention aims to provide the instrument backlight reflecting part structure. By adopting the technical scheme provided by the invention, the technical problems that the cost is high, the light insulation effect is poor and light is not uniform due to the adoption of a white backlight reflecting part at present are solved.

Description

technical field [0001] The invention relates to the technical field of instrument reflectors, in particular to a structure of instrument backlight reflectors. [0002] technical background [0003] Traditional instruments are used to make backlight reflectors are made of white materials. As the plane combination instrument is becoming more and more popular, if the traditional design scheme is still used, it will lead to more parts and higher material costs. Products are not competitive. [0004] like figure 1 As shown, the white backlight reflector 3 and the black plastic panel 4 can be made into one part, but since the backlight reflector is made of white material, the backlight reflector 3 and the black plastic panel 4 have different colors and must be split into two parts. Parts increase unnecessary costs; and the white backlight reflector 3 and the black plastic panel 4 are mostly fixed by buckles, heated, melted, welded, screwed or glued, resulting in high cost of the ...
