Description

Technical Field

[0001] The present invention relates to a display module in the technical field of LED display screens. Background Art

[0002] Traditional LED display module chassis are made of a one-piece plastic shell, a die-cast aluminum shell, or a die-cast magnesium alloy chassis. Die-cast chassis require secondary machining and painting, which is costly, and the PCB IC surface cannot be removed, making maintenance inconvenient. The module chassis of the present invention is an industry first, featuring a split-body design. The module has a removable back cover, which is made of aluminum or aluminum alloy through a stretching process. This back cover provides excellent strength and heat dissipation, while being less expensive and lighter than die-cast chassis. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to improve the heat dissipation efficiency of the LED display module, facilitate the maintenance of the IC surface of the PCB, increase the module strength, improve the stability of the module, and extend the service life.

[0004] Based on the above purpose, the present invention provides an LED display module device with an aluminum stretched back cover, including: a display light board, a module hollow bottom shell, a detachable aluminum heat dissipation back cover, a back cover waterproof ring, and a back cover fastening screw. It is characterized in that: a detachable aluminum heat dissipation back cover is provided on the back of the module hollow bottom shell, the detachable aluminum heat dissipation back cover is detachably connected to the back of the module bottom shell, and the back cover waterproof ring is placed between the module hollow bottom shell and the detachable aluminum heat dissipation back cover to play a waterproof role.

[0005] The detachable aluminum heat dissipation back cover is produced by a stamping and stretching process, and a stretching bulge and a groove can be added in the middle of the back cover to increase the strength of the back cover and the surface area for heat dissipation. BRIEF DESCRIPTION OF THE DRAWINGS

[0006] FIG1 is a schematic structural diagram of an LED display screen module device with an aluminum stretched rear cover according to the present invention; FIG2 is an exploded view of an LED display screen module device with an aluminum stretched rear cover according to the present invention; FIG3 is a schematic structural diagram of the stretched rear cover of the LED display screen module device with an aluminum stretched rear cover after assembly according to the present invention; Among them, A: display light board B: module hollow bottom shell C: back cover waterproof ring D: detachable aluminum heat dissipation back cover E: back cover fastening screw D_1: back cover stretch groove feature D_2 back cover stretch convex feature. DETAILED DESCRIPTION

[0007] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0008] See also Figure 1 2 is a schematic structural diagram of an LED display module device with an aluminum stretched back cover according to the present invention, comprising: a display light board A, a module hollow bottom shell B, a detachable aluminum heat dissipation back cover D, a back cover waterproof ring C, and a back cover fastening screw E. The back of the module hollow bottom shell B is provided with a detachable aluminum heat dissipation back cover D, the detachable aluminum heat dissipation back cover D is detachably connected to the back of the module bottom shell B and is locked and fixed with the back cover fastening screws E. The back cover waterproof ring C is placed between the module hollow bottom shell B and the detachable aluminum heat dissipation back cover D to play a waterproof role.

[0009] See also Figure 3 This is a schematic diagram of the structure of the stretched back cover of the LED display module device with an aluminum stretched back cover after assembly. The detachable aluminum heat dissipation back cover D is produced by a stamping and stretching process, and a stretched convex bulge D_2 and a groove D_1 are added in the middle of the back, which greatly increases the strength of the back cover and increases the surface area for heat dissipation.

[0010] As described above, the LED display screen module device with an aluminum stretched rear cover of the present invention increases module strength, improves module stability, and prolongs service life in the LED field.

[0011] Those skilled in the art should understand that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
