DETAILED DESCRIPTION

[0019] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0020] An LED module structure includes a housing 1 with an open top, wherein a rectangular frame 2, a display panel 3, a scattering light guide plate 4, a main control board 5 and a heat dissipation plate 6 are sequentially arranged in the housing 1 from top to bottom:

[0021] The four groups of top corners in the housing 1 are all provided with L-shaped plates 7 located below the rectangular frame 2, wherein the L-shaped plates 7 are connected to the inner wall of the housing 1 through a connecting plate 8, and the display panel 3, the scattering light guide plate 4, the main control board 5 and the heat dissipation plate 6 are arranged in the opening formed between the four groups of L-shaped plates 7, and an elastic plate 9 with a wavy structure is arranged on the inner wall of the housing 1, wherein a bolt 10 for locking one end of the elastic plate 9 to the side walls of the display panel 3, the scattering light guide plate 4, the main control board 5 and the heat dissipation plate 6 is screwed on the housing 1;

[0022] The cavity formed between the recessed portion of the elastic plate 9 and the inner wall of the shell 1 is filled with a protrusion 11, wherein the protrusion 11 is fixedly connected to the bottom of the rectangular frame 2, and a screw hole 12 is arranged in the side wall of the protrusion 11, wherein a through hole 14 corresponding to the screw hole 12 is arranged on the side wall of the shell 1, and a stud 13 is screwed in the screw hole 12, and a cross groove is arranged at the end of the stud 13.

[0023] In this embodiment, an extension portion 15 extending to the top of the side wall of the housing 1 is provided on the top of the outer side wall of the rectangular frame 2, wherein a protrusion 16 is provided on the bottom end surface of the extension portion 15, and a clamping groove 17 for accommodating the protrusion 16 is provided on the top wall of the housing 1. The connection stability of the rectangular frame 2 on the housing 1 is enhanced by fixing the protrusion 16 through the clamping groove 17.

[0024] In this embodiment, the inner diameter of the through hole 14 matches the diameter of the stud 13, wherein a ring 18 is arranged in the opening of the through hole 14 outside the housing 1, and the length of the stud 13 is greater than the depth of the through hole 14. The ring 18 prevents the stud 13 from slipping out of the through hole 14.

[0025] In this embodiment, part of the cavity formed between the recessed portion of the elastic plate 9 and the inner wall of the housing 1 is filled with elastic filler, and part of the cavity is provided with a protrusion 11 and a bolt 10 .

[0026] like Figure 3 As shown, both ends of the connecting plate 8 are fixedly connected to the L-shaped plate 7 and the top corners of the housing 1, respectively, wherein the connecting plate 8, the L-shaped plate 7 and the top end of the elastic plate 9 are in the same horizontal plane.

[0027] like Figure 2 As shown, the depth of the screw hole 12 is not less than the length of the stud 13 , wherein the number of screw holes 12 on each group of protrusions 11 is not less than two groups, and the multiple groups of screw holes 12 are arranged in parallel on the side wall of the protrusion 11 .

[0028] The working principle of the present invention is as follows: the display panel 3, the scattering light guide plate 4, the main control board 5 and the heat dissipation plate 6 are stacked in sequence in the shell 1, wherein the top corners of the above components are wrapped by four groups of L-shaped plates 7 to protect them, prevent the top corners from being bumped and broken, and prevent them from horizontal displacement. In the above process, the four groups of elastic plates 9 clamp and limit the edges of the above components, and by rotating the bolts 10, the elastic plates 9 can be tightly attached to the outer wall of the above components, and further the elastic plates 9 can fix the side walls of the above components, and the wavy elastic plates 9 can reduce the contact area between them and the side walls of the above components, reducing the probability of them causing damage to the side walls of the above components.

[0029] Then, the protrusion 11 is inserted into the cavity formed by the recessed portion of the elastic plate 9 and the inner wall of the shell 1 through the rectangular frame 2, and the rectangular frame 2 presses the display panel 3 and other components into the shell 1. At this time, the stud 13 is aligned with the corresponding through hole 14, and then the screwdriver can be inserted into the through hole 14 through the inner diameter of the ring 18 and embedded in the cross groove to rotate the stud 13, so that one end thereof slides out of the screw hole 12 and slides into the through hole 14, so as to prevent the protrusion 11 and the rectangular frame 2 from sliding out of the shell 1 by pressing the stud 13 through the through hole 14, thereby fixing the display panel 3, the scattering light guide plate 4, the main control board 5 and the heat sink 6 in the shell 1, wherein when the rectangular frame 2 needs to be disassembled, it is only necessary to rotate the stud 13 in sequence to make it slide into the screw hole 12, and then the rectangular frame 2 and the protrusion 11 can be conveniently pulled out of the shell 1.

[0030] The present invention wraps the top corners of the display panel 3, the scattering light guide plate 4, the main control board 5 and the heat dissipation plate 6 through four groups of L-shaped plates 7 to protect them, prevent their top corners from being bumped and broken, and prevent them from horizontal displacement. The multiple groups of wavy elastic plates 9 can not only clamp and fix the side walls of the above-mentioned components over a large range, but also reduce the contact area between them to improve the safety of the side walls of the above-mentioned components. When disassembling the rectangular frame 2, it is only necessary to rotate the studs 13 in sequence to make them slide into the screw holes 12, and then the rectangular frame 2 and the protrusions 11 can be conveniently pulled out of the shell 1.

[0031] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
