Description

Technical Field

[0001] The invention relates to the field of mechanical equipment, and in particular to a stable backlight structure. Background Art

[0002] like Figure 1 As shown, the outer edges and window edges of the iron frame are designed to be straight edges ( Figure 1 Solid line), during the actual stamping process, the iron frame raw material within the window range is cut off, the raw material releases internal stress, and pulls the edge of the iron frame window to produce a concave deformation (such as Figure 1 dotted line); the backlight is emitted through the iron frame window. When the iron frame window is concave, the light at the edge of the window is blocked. After the client assembles the LCD glass, the pixels at the edge of the LCD glass are blocked by the backlight, resulting in the risk of incomplete edge display. Summary of the invention

[0017] The structure of the present invention is further described below in conjunction with the accompanying drawings.

[0018] Reference Figures 1 to 6The stable backlight structure of the present invention comprises a shell 1, a middle iron frame 2 arranged in the shell, and a backlight body 3 arranged in the middle iron frame. A backlight body mounting groove 11 is arranged in the shell, and a middle iron frame mounting platform 12 is arranged on the side wall of the backlight body mounting groove. The middle iron frame 2 comprises a hollow horizontal frame 21, and the edge of the horizontal frame is bent upward by 90 degrees to form an upper vertical frame 22. The top three surfaces of the upper vertical frame are bent outward by 90 degrees to form a T-shaped buckle 23. The T-shaped buckle is located on the top surface of the shell, and the shell 1 is provided with a T-shaped slot 13 that cooperates with the T-shaped buckle. The fourth surface of the upper vertical frame 22 is provided with a notch 221, and the edge of the horizontal frame corresponding to the notch is bent downward 90 degrees to form a lower vertical frame 24. The shell 1 is provided with a lower vertical frame slot 14 corresponding to the lower vertical frame, and the lower vertical frame is clamped on the wall of the lower vertical frame slot. The horizontal frame is located on the middle iron frame mounting platform, and the horizontal frame protrudes inward from the middle iron frame mounting platform. The backlight structure also includes a first pressing plate 4 provided on the horizontal frame and a second pressing plate 5 provided on the T-shaped buckle. In this embodiment, the first pressing plate is bonded to the horizontal frame by glue. The second pressing plate is bonded to the shell by glue. Thereby, the middle iron frame is firmly fixed. The horizontal frame of the stable backlight structure of the present invention protrudes inward from the middle iron frame mounting platform, thereby pressing the backlight body into the backlight body mounting groove, and the top three surfaces of the upper vertical frame are bent outward 90 degrees to form a T-shaped buckle, and the T-shaped buckle is clamped with the T-shaped slot on the shell, and the lower vertical frame is clamped on the lower vertical frame slot wall, the first pressing plate presses the horizontal frame, and the second pressing plate presses the T-shaped buckle, and the surrounding of the middle iron frame is subjected to the lower vertical frame slot on the shell and the outward pulling force of the T-shaped slot on the middle iron frame, which offsets the internal stress of the inward deformation of the middle iron frame, thereby improving the concave deformation of the middle iron frame monomer, the first pressing plate presses the horizontal frame, and the second pressing plate presses the T-shaped buckle to make the overall structure stable and not easy to deform.

[0019] In this embodiment, a shell buckle 15 is protruding outwardly on the lower vertical frame slot wall of the shell 1, and a shell buckle engaging hole 241 cooperating with the shell buckle is provided on the lower vertical frame 24. When the lower vertical frame is engaged with the lower vertical frame slot wall, the shell buckle is engaged with the shell buckle engaging hole, so that the middle iron frame is fixed more stably.

[0020] In this embodiment, frame buckles 221 are punched outwardly around the upper vertical frame 22, and frame buckle slots 15 cooperating with the frame buckles are provided on the shell 1. The upper vertical frame and the shell are connected by the frame buckles, so that the upper vertical frame and the shell are firmly connected.

[0021] In this embodiment, the outer surface of the upper vertical frame 22 is provided with anti-skid protrusions 222. The anti-skid protrusions prevent the upper vertical frame from sliding with the housing, thereby making the connection between the upper vertical frame and the housing more stable.
