Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1-3, the integrated structure of a rubber frame and an iron frame of a backlight source comprises an iron frame 10 and a rubber frame 20 injection-molded on the inner side of the iron frame 10, wherein the iron frame 10 has a bottom plate 11 and a frame edge 12 surrounding the edge of the bottom plate 11, a plurality of rubber fixing holes 13 are formed in the edges of the frame edge 12 and the bottom plate 11, and 180 parts are arranged at the upper end of the frame edge 12 0 The folded edge 14 is folded inwards, a glue fixing space is formed between the lower end face of the folded edge 14 and the upper surface of the bottom plate 11, and part of the glue frame 20 is embedded in the glue fixing hole 13 and the glue fixing space.
Specifically, in the present invention, the upper end of the rubber frame 20 covers the upper end surface of the frame edge 12 of the iron frame 10. The cross section of the rubber frame 20 is L-shaped. The rubber frame 20 has a vertical extension 21 and a horizontal extension 22 integrally connected, the horizontal extension 22 is connected to the lower end of the vertical extension 21, and the horizontal extension 22 protrudes toward the center of the bottom plate 11.
