[0002] When making a display, a light bar needs to be placed in the back panel to ensure brightness. However, the existing display back panel has a small space for accommodating the light bar, and the heat dissipation space is small, resulting in failure to dissipate heat in time, which easily causes the light bar to burn out and reduces its service life. In addition, as the thickness of the display becomes thinner and thinner, the guide threading holes on the back panel are set at the corners and can no longer meet the needs. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to make the above features and advantages of the present invention more understandable, embodiments are given below with reference to the accompanying drawings for detailed description, but the present invention is not limited thereto.

[0021] refer to Figures 1 to 6

[0022] A display back panel heat dissipation structure includes a back panel body 100, wherein the back panel body is provided with folded edges 101 turned toward the front side on all sides, and a heat dissipation recess 102 concave toward the rear is provided in the horizontal direction at the lower part of the back panel body, and the height 103 of the heat dissipation recess is 30-50 mm, and a threading hole 104 is provided in the middle part of the lower side of the heat dissipation recess and close to the folded edge located at the lower side, so that the wires of the light bar can pass through the threading hole. Limiting protrusions 105 turned toward the upper side are provided in the horizontal direction at intervals on the upper edge of the front part of the folded edge located at the lower side of the back panel body, and a light bar installation area 106 is formed between the inner side surface of the limiting protrusion and the back panel body, so that the light bar is limited in the light bar installation area by the limiting protrusion.

[0023] In this embodiment, in order to better position and install the back panel in the positioning groove of the display housing, each folded edge of the back panel body is provided with positioning protrusions 107 protruding outward at intervals along the outer wall of the length direction thereof.

[0024] In this embodiment, rear convex cavities 109 are arranged at intervals on the top and both sides of the area 108 located on the upper side of the heat dissipation recess on the back panel body, and bolt holes 110 are arranged in the rear convex cavities so that screws can be inserted through the bolt holes to achieve the connection and fixation between the back panel and the display housing.

[0025] In this embodiment, the back side of the rear convex cavity is flush with the back side of the heat dissipation recess, which helps to ensure flatness during installation.

[0026] In this embodiment, since the thickness of the back plate is usually thin, in order to strengthen the strength of the back plate, a rear concave area 111 is provided in the area of ​​the back plate body located on the upper side of the heat dissipation concave portion, and a plurality of forward convex reinforcing ribs 112 are provided in the rear concave area. The front side surface of the reinforcing ribs is flush with the front side surface of the area of ​​the back plate body located on the upper side of the heat dissipation concave portion.

[0027] In this embodiment, a first punching positioning hole 113 for use in preparing the back plate punching is provided in the upper middle part of the reinforcing rib portion located at the uppermost side, and a pair of second punching positioning holes 115 are provided in the lower part of the area of ​​the back plate body located at the upper side of the heat dissipation recess. In order to prevent light leakage from the first punching positioning hole and the second punching positioning hole, a light leakage prevention material patch 114, such as waterproof tape, is attached to the rear side of the first punching positioning hole and the rear side of the second punching positioning hole.

[0028] If the words "first", "second" and the like are used in the above-mentioned utility model to limit components, those skilled in the art should know that the use of "first" and "second" is only for the convenience of description to distinguish the components. Unless otherwise stated, the above-mentioned words have no special meaning.

[0029] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the fixed connection to each other can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except where it is obviously impossible to use an one-piece molding process).

[0030] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the above utility model include states or shapes that are approximate, similar or close thereto.

[0031] Any component provided by the utility model can be assembled from multiple separate components, or can be a separate component manufactured by an integrated molding process.
