[0040] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0041] like Figures 1-12 As shown, this utility model proposes an LED display module bottom shell structure, including a frame 100, a plurality of first rib beams 200, a plurality of second rib beams 300 and two assembly plates 400. The frame 100 is provided with a main rib beam 101 located at the center line of the frame 100.

[0042] It should be noted that the frame 100 has a rectangular structure and can be a one-piece structure or a structure assembled from multiple side strips. The assembly methods can include welding, screw fixing, riveting, mortise and tenon assembly, etc. The main beam 101 is positioned at the center line of the frame 101, as shown in the attached diagram. Figure 4 As shown, the width of the main beam 101 is wider than the side width of the frame 100. While serving as the main beam to strengthen the frame 100, it also serves as the connection medium for the two assembly plates 400 in the subsequent process.

[0043] An anti-disengagement member 102 is disposed at the edge of the frame 100, two fitting grooves 1011 are disposed on the main bone beam 101, a plurality of first bone beams 200 are longitudinally arranged on the frame 100 and parallel to the main bone beam 101, and a plurality of second bone beams 300 are transversely arranged on the frame 100 and orthogonal to the main bone beam 101;

[0044] It should be noted that the plurality of first bone beams 200 and the plurality of second bone beams 300 are arranged in a grid pattern within the frame 100;

[0045] Two assembly flat plates 400 are respectively embedded on the frame 100 and placed on both sides of the main bone beam 100. One side of the assembly flat plate 400 is provided with a notch 403 that fits with the anti-disengagement member 102, and the other side of the assembly flat plate 400 is provided with a connecting member 404 connected to the assembly groove 1011, wherein the two assembly flat plates 400 are respectively connected to each of the first bone beams 200 and each of the second bone beams 300.

[0046] It should be noted that the number of the assembly flat plates 400 is not limited to two. In this embodiment, an arrangement structure with two assembly flat plates 400 is adopted, and the assembled integrated frame 100 and the assembly flat plates 400 are glued into a whole by engineering plastic through an injection molding process, wherein the frame 100 and the assembly flat plates 400 form an aluminum-plastic rubber position and a sealant position, which improves the strength and weather resistance of the large-size LED display module as well as the conditions for long-term reliable operation of electronic components in terms of waterproofing and heat dissipation, and facilitates high-quality and stable operation of the LED screen;

[0047] Refer to the accompanying Figure 6 , in one embodiment of the present application, the two assembly grooves 1011 penetrate through the main bone beam 101 and are combined with each other to form a a shape of Chinese character "hui", the structural shape of the connecting member 404 corresponds to the shape of the assembly groove 1011, so as to improve the connection strength between the two assembly flat plates 400 and the main bone beam 101. Certainly, this structure can also be used when more than two assembly flat plates 400 are used, but it is only limited to the two assembly flat plates 400 close to the main bone beam 101, and the rest of the assembly flat plates 400 can be connected by using each first bone beam 200 as a connection medium, or by adding other fixing structures such as screws, fasteners and the like.

[0048] In one embodiment of the present application, each first bone beam 200 and the frame 100 are of an integral structure, and the cross section of the first bone beam 200 is of a trapezoidal structure.

[0049] In one embodiment of the present application, the assembly flat plate 400 is provided with a long groove 401 fitted with the first bone beam 200, and the cross section of the long groove 401 is of a trapezoidal notch structure.

[0050] Refer to the accompanying Figure 7It should be noted that when the elongated groove 401 is fitted with the first rib beam 200, the elongated groove 401 only partially covers the two sides of the first rib beam 200. Therefore, in order to achieve full coverage of the two sides of the first rib beam 200 and reduce injection molding costs, wrapping strips 4011 extend from both sides of the opening of the elongated groove 401. The extension direction of the two wrapping strips 4011 corresponds to the trapezoidal groove structure of the elongated groove 401. From the cross-section of the elongated groove 401, the two wrapping strips 4011 are extensions of the two trapezoidal sides of the trapezoidal groove structure. At this time, when the elongated groove 401 is fitted with the first rib beam 200, the two wrapping strips 4011 are completely attached to the two sides of the first rib beam 200, achieving full coverage, thereby strengthening the connection strength between the assembly plate 400 and the first rib beam 200. The trapezoidal structure design is to facilitate assembly while also strengthening the connection strength.

[0051] In one embodiment of this application, the second rib beam 300 traverses the entire frame 100 and is positioned below each assembly plate 400.

[0052] In one embodiment of this application, a plurality of positioning grooves 301 are provided on the second bone beam 300, and a protrusion 402 that engages with the positioning groove 301 is provided on the side of each mounting plate 400 facing the second bone beam 300.

[0053] See appendix Figure 7 as well as Figure 8 It should be noted that the positioning groove 301 is a trapezoidal groove, the protrusion 402 is a trapezoidal block, and the protrusion 402 is the protrusion at the bottom of the elongated groove 401. That is, the position of the positioning groove 301 corresponds to the position of the elongated groove 401. Each positioning groove 301 corresponds to one elongated groove 401. After assembly, the second rib beam 300 is connected to the corresponding multiple first rib beams 200, reducing the shrinkage deformation of each first rib beam 200 and the assembly plate 400, and improving the strength of the entire bottom shell.

[0054] In one embodiment of this application, the first bone beam 200 is provided with a plurality of fixed wings 302 and a plurality of fasteners 303, each fastener 303 corresponding to a fixed wing 302, the fasteners 303 respectively passing through the corresponding second bone beam 300 and the mounting plate 400, and being fixedly connected to the corresponding fixed wing 302, so as to fix the first bone beam 200, the second bone beam 300 and the mounting plate 400 together.

[0055] In one embodiment of this application, the second rib 300 has an "I" shaped structure.

[0056] It should be noted that the second bone beam 300 is fixed to the frame 100 by screws and runs across the width of the frame 100. Each positioning groove 301 on it is engaged with the protrusion 402 of each mounting plate 400. The first bone beam 200, the second bone beam 300 and the mounting plate 400 are fixed together by multiple fasteners 303. The fasteners 303 are screw structures, and the fixing wings 302 have holes for connecting to the fasteners 303.

[0057] This invention can be achieved by setting up a stretching mold for the "I"-shaped second rib beam 300 and the assembly plate 400, preferably a stretching aluminum mold and stretching aluminum material, and setting up an injection mold for bonding the assembly plate 400 and the "I"-shaped second rib beam 300, preferably a hot runner injection molding machine, and the material is nylon engineering material. The stretched aluminum assembly plate 400 and the "I"-shaped aluminum second rib beam 300 are cut, milled and riveted, and then treated with an oxidation process to become injection-molded assembly semi-finished parts. The processed and assembled semi-finished parts are placed into the injection mold to form an assembly display light panel mold bottom shell structure. For the sake of convenience, this invention only assembles two aluminum assembly plates 400. If necessary, more than two plates can be assembled to form a larger display bottom shell structure.

[0058] In one embodiment of this application, the bottom shell structure of the LED display module further includes a plurality of through slots 500, which are arranged on two mounting plates 400 and are used to penetrate the two sides of the mounting plates 400.

[0059] It should be noted that the multiple through slots 500 are connected to the frame 100, either by screws or by an integrated structure. The through slots 500 pass through both sides of the mounting plate 400, that is, the upper and lower surfaces, to serve as through holes for the electrical connection sockets of the LED display board and through holes for glue injection.

[0060] In one embodiment of this application, the LED display module bottom shell structure further includes two handle bases 600 and a U-shaped handle 700. The two handle bases 600 are respectively mounted on two assembly plates 400 and are positioned on the center line of the frame 100. The two ends of the U-shaped handle 700 are respectively fixedly connected to the two handle bases 600.

[0061] It should be noted that the hollow U-shaped handle 700 spans two assembly plates 400 horizontally and perpendicularly to the center line, and is located at the center of the frame 100. The end face of the U-shaped handle 700 has through holes for locking the nut holes of the assembly plates. The hollow part of the U-shaped handle 700 allows wire harnesses to pass through the hollow space and connect the wire harnesses to the circuit boards inside the assembly plates 400 on both sides.

[0062] It should be noted that the above descriptions are one or more embodiments provided in conjunction with specific content, and do not imply that the specific implementation of this utility model is limited to these descriptions. Any methods or structures that are similar to or identical to those of this utility model, or any technical deductions or substitutions made based on the concept of this utility model, should be considered within the scope of protection of this utility model.
