Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted screens, in particular to a backlight source middle frame. Background Art

[0002] With the development of science and technology, electronic products have been widely promoted and applied, and screens are becoming more and more common in cars. The screen needs a backplane to assist in ensuring that the light is emitted from behind the LCD screen. Some indicators such as the brightness and uniformity of the backplane have a direct impact on the relevant performance of the LCD screen. The backplane needs to be fixed with a middle frame when it is assembled into a backlight source. Because the backplane is a metal casting, metal shavings may be generated between the ordinary middle frame and the backplane due to friction, affecting the normal use and service life of the screen, and the ordinary middle frame may cause the light source to diffuse. To this end, we proposed a backlight source middle frame to solve the above problems. Utility Model Content

[0003] The utility model aims to solve the shortcomings of the prior art that metal scraps may be generated due to friction between the common middle frame and the back plate and the common partition frame may cause the diffusion of the light source, and proposes a backlight source middle frame.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A backlight source middle frame is designed, including a middle frame body, a plurality of bent side panels bent backwards are integrally formed on the outer wall of the middle frame body, buckles are integrally formed on the outer wall of the bent side panels away from the middle frame body by stamping, and the outer wall of the buckle is coated with a wear-resistant coating for reducing wear, a matte coating for preventing light source diffusion is coated around the viewing area of ​​the middle frame body, a pair of fixing plates bent forwards are integrally formed on the outer wall of the middle frame body, and the outer wall of the fixing plate close to the middle frame body is coated with a wear-resistant coating, a strip-shaped plug hole is opened on the outer wall of the fixing plate, and the plug hole is used for inserting and connecting with the back panel buckle.

[0006] Preferably, a rectangular groove for reducing the contact area is formed on the front end surface of the middle frame body.

[0007] Preferably, a plurality of bending plates are integrally formed at the rear end of the bending side plate, and each bending plate is arranged between two adjacent buckles.

[0008] Preferably, one end of the bending plate away from the bending side plate is bent outward at a right angle.

[0009] Preferably, the wear-resistant coating is a yellow coating.

[0010] Preferably, one end of the bending plate away from the bending side plate is integrally formed with a clamping plate located at the left and right ends.

[0011] Preferably, the matte coating is a black coating.

[0012] The utility model proposes a backlight source middle frame, which has the beneficial effect that the backlight source middle frame can not only fix the middle frame body on the back plate through the buckles and the clamping plates, but also can avoid the generation of metal chips due to friction between the buckles and the screen, between the middle frame body and the back plate, and between the bending plate and the backlight plate during installation through the wear-resistant coating, thereby avoiding the metal chips from affecting the normal use and life of the screen. In addition, the matte coating can prevent the diffusion of the light source. BRIEF DESCRIPTION OF THE DRAWINGS
