[0020] The preferred implementation modes provided by the utility model are described in detail according to the accompanying drawings.

[0021] Figures 4 to 6 , which is a preferred embodiment of a backlight support structure provided by the utility model. Figures 4 to 6As shown, the support structure for backlight includes a plastic frame 10 and a metal frame 20. The plastic frame is provided with a placement groove 11 for inserting the folded edge of the metal frame. The plastic frame 10 is also distributed with a plurality of buckles 12 for positioning the metal frame. The metal frame 20 is provided with a plurality of buckle holes 21 that cooperate with the buckles. In this way, the folded edge of the metal frame 20 is placed in the placement groove on the side wall of the plastic frame, and each buckle 12 on the plastic frame cooperates with each buckle hole 21 of the metal frame. The plastic frame 10 and the metal frame 20 are positioned by using the buckle structure to prevent the plastic frame 10 from deformation and displacement, thereby reducing production costs and improving production efficiency.

[0022] The buckle protrusion of the buckle 12 faces the outside of the plastic frame, which is convenient for matching with the buckle hole 21 on the metal frame 20. The avoidance groove 13 corresponding to the buckle 12 on the outer wall of the plastic frame 10 is convenient for making the plastic frame mold and checking whether the buckle assembly is buckled on the metal frame 20.

[0023] The metal frame 20 includes a bottom plate 201 and a folded edge 202 formed by bending the side wall of the bottom plate. The folded edge 202 is provided with buckle holes 21 at positions corresponding to the buckles 12. The buckle holes 21 extend to the bottom plate 201 of the metal frame 20. The metal frame 20 can be made of metal iron material.

[0024] The plastic frame 10 includes a first frame body 14, and a placement groove 11 is arranged on the side wall of the first frame body 14. The placement groove 11 is formed by a first side wall 111 and a second side wall 112. The height of the second side wall 112 is lower than that of the first side wall, so that a step is formed between the first side wall 111 and the second side wall 112. When the folded edge of the metal frame is placed in the placement groove 11, the first side wall 111 fits the inner wall of the folded edge of the metal frame, and at the same time, the top of the first side wall 111 is pressed against the bottom plate of the metal frame, and the top of the second side wall 112 fits the surface of the folded edge of the metal frame.

[0025] The corner position of the folded edge on the metal frame forms a step folded edge 2021, and the corner position of the placement groove 11 forms a step groove 1101 corresponding to the step folded edge, so as to ensure the positioning of the metal frame 20 and the plastic frame 10; and facilitate the subsequent folded edge on one side of the metal frame to pass through the plastic frame 10 and extend out.

[0026] The first frame body 14 is formed by enclosing a first rubber frame long side 1401, a third rubber frame long side 1403 and two second rubber frame short sides 1402, and the two second rubber frame short sides 1402 are arranged opposite to each other; the buckles 12 are distributed on the first rubber frame long side 1401 and the two second rubber frame short sides 1402, and the mounting grooves 11 are arranged on the side walls of the first rubber frame long side 1401 and the two second rubber frame short sides 1402; an LCD retaining wall 1404 is arranged on the third rubber frame long side 1403, so that the folded edge on one side of the metal frame passes through the third rubber frame long side 1403 of the rubber frame 10, the film material in the LCM module is positioned by the LCD retaining wall 1404, and the folded edges on the other sides of the metal frame 20 are placed in the mounting grooves 11, and the folded edges on four sides of the metal frame 20 are embedded in the mounting grooves 11 of the rubber frame to position the metal frame 20 and the rubber frame 10.

[0027] As a preferred embodiment, Figure 4 and Figure 5 As shown, the third rubber frame long side 1043 is a long connecting side, and the two ends of the long connecting side are respectively connected to the ends of the two second rubber frame short sides, and the LCD retaining wall 1404 is arranged on the long connecting side. As another preferred embodiment, the third rubber frame long side 1043 is two short connecting sides, and the two short connecting sides 1043 are independent of each other. The two short connecting sides 1043 are respectively connected to the ends of the corresponding second rubber frame short sides 1402, and the LCD retaining wall 1444 is arranged on the two short connecting sides.

[0028] The support structure for backlight provided by the utility model places the folded edge of the metal frame 20 into the placement groove 11 on the side wall of the plastic frame 10, and the buckles 12 on the plastic frame 10 cooperate with the buckle holes 21 of the metal frame. The plastic frame and the metal frame are positioned by using the buckle structure to prevent deformation and displacement of the plastic frame, which can reduce the attachment of double-sided tape, reduce production costs, and improve production efficiency.
