Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Unless otherwise defined, all technical and scientific terms used in this article have the same meaning as those commonly understood by those skilled in the technical field to which this utility model belongs; the terms used in the specification of this utility model in this article are only for the purpose of describing specific implementations and are not intended to limit this utility model; the term "and / or" used in this article includes any and all combinations of one or more of the related listed items.

[0023] As Figure 1 shown, a module bottom shell includes a bottom shell structure 1, and is characterized in that: the bottom shell structure 1 includes a first bottom shell 11 and a second bottom shell 12 located on one side of the first bottom shell 11 and correspondingly connected to the first bottom shell 11. The first bottom shell 11 is a carbon fiber shell processed by a texturing process, and the second shell 12 is made by an injection molding process. A convex surface 13 protruding away from the second bottom shell 12 is provided on the first bottom shell 11, and a texturing pattern 14 is arranged on the convex surface 13. A connecting structure 2 is fixedly connected to the side of the second bottom shell 12 away from the first bottom shell 11.

[0024] In this embodiment, the present utility model proposes a module bottom shell, including a first bottom shell made of carbon fiber material. The use of carbon fiber material for the LED module bottom shell has the following advantages: Carbon fiber is a lightweight material, and its density is only 1 / 4 of that of steel materials and 1 / 5 of that of aluminum materials. Therefore, using carbon fiber as the material for the LED module bottom shell can effectively reduce the overall weight and facilitate handling and installation; the tensile strength of carbon fiber is 56 times higher than that of steel, and the compressive strength is more than 2 times higher than that of aluminum. This high-strength characteristic enables the carbon fiber bottom shell to withstand a large load and improve the structural stability of the LED module; carbon fiber performs well in high-temperature environments and is not easily oxidized or expanded. At the same time, it also has good heat conduction performance, which helps the LED module dissipate heat and improve the service life; carbon fiber has good chemical stability and is not easily corroded. This enables the carbon fiber bottom shell to work stably for a long time in harsh environments such as outdoors; carbon fiber is a conductive material, which helps the flexibility of the LED module in circuit design and layout; the application of carbon fiber enables the LED module bottom shell to achieve a thin and light design, further expanding the application range of the LED display screen, especially in installation sites with load restrictions.

[0025] Further improved, the first bottom shell adopts a textured pattern. The texturing process can significantly enhance the appearance texture of the LED module bottom shell, presenting a more diverse or brand-new design effect. The texturing process can form various patterns, such as stripes, images, wood grains, leather grains, etc. These patterns can add unique visual effects to the product; through texturing treatment, some defective marks generated during the manufacturing process, such as shrinkage and joint lines, can be covered, thus improving the appearance quality of the product;: After being processed by the texturing and sandblasting procedures, the surface hardness of the LED module bottom shell will increase, which helps prevent scratching and wear and improves the durability of the product; the texturing treatment can be made into a matte or semi-gloss surface, and such a surface has good anti-slip and anti-rotation performance, increasing the safety and stability of the product; the texturing treatment can eliminate or reduce the reflection of light on the surface of the LED module bottom shell, helping to reduce eye fatigue and improve the user experience; the cost of the texturing process is relatively low. After the mold is textured, the yield rate of the injection-molded product can be greatly improved, which helps reduce production costs and improve production efficiency.

[0026] It should be noted that the existing problems mainly solved by the present utility model are as follows:

[0027] 1. Weight problem: Using carbon fiber material, the density is only 1 / 5 of that of aluminum material, greatly reducing the weight of the bottom shell.

[0028] 2. Strength problem: The tensile strength of carbon fiber is 56 times higher than that of steel, and the compressive strength is more than 2 times higher than that of aluminum, improving the structural strength.

[0029] 3. Heat dissipation problem: Carbon fiber has good thermal conductivity, which helps the LED module dissipate heat and extends its service life.

[0030] 4. Corrosion resistance problem: Carbon fiber has good chemical stability and is corrosion-resistant, suitable for long-term use in harsh environments.

[0031] 5. Electromagnetic shielding problem: Carbon fiber has conductivity, which helps with circuit design and electromagnetic shielding.

[0032] 6. Cost problem: Adopting the texturing process can improve the product yield rate and reduce production costs.

[0033] 7. Appearance problem: The texturing process enhances the appearance texture and can cover manufacturing marks.

[0034] 8. Installation problem: Designed an installation method combining magnets and screw holes, improving the convenience and flexibility of installation.

[0035] 9. Positioning accuracy problem: Added positioning posts to ensure accurate alignment during installation.

[0036] 10. Compatibility issue: The bottom case is compatible with pixel pitches of 3.91 mm and 2.604 mm to meet different requirements.

[0037] As Figure 2 shown, magnets 21 are fixedly provided at the four corners of the second bottom case 12. A pair of screw holes 22 that are fixedly connected to the bottom case and are in the same vertical or horizontal direction as the magnets 21 are provided between the magnets 21. Positioning posts 23 are provided on both sides of the second bottom case 12 between the screw holes 22. A handle screw hole 24 that is provided between the graining patterns 14 and penetrates the bottom case structure 1 is provided on the convex surface 13. A through hole 25 that penetrates the bottom case structure 1 is provided on one side of the convex surface 13. A waterproof rubber ring 26 is provided around the opening of the through hole 25. A number of evenly distributed bottom case screw holes 27 are provided inside the second bottom case 12. A number of face mask screw holes 28 are provided on the periphery of the bottom case screw holes 27.

[0038] In this implementation, there are magnets at the four corners of the bottom case, and two screw holes are provided on each side. This design allows customers to choose to use magnetic attraction or screw fixation, or both methods simultaneously when installing the display screen, thus providing higher flexibility and convenience; there are positioning posts on the upper and lower sides of the bottom case. The positioning posts are used to ensure that the LED module can be accurately aligned during assembly or installation, avoiding affecting the overall effect due to position deviation. This is crucial for ensuring the image quality of the LED display and the stability of the module structure; there are holes on the bottom case corresponding to the module installation holes to ensure that the module can be correctly installed. In addition, the bottom case is compatible with pixel pitches of 3.91 mm and 2.604 mm to meet the needs of different customers and provide a wider range of application possibilities. This new type of module bottom case solves the problems of the existing LED module bottom case in terms of weight, strength, chemical stability, heat dissipation, electromagnetic shielding, appearance design, installation convenience, etc. through the mixed use of carbon fiber materials, graining process, and special installation design.
