[0028] As Figures 1 to 3 shown, a lightweight LED display box body effectively reduces the overall weight while ensuring its own strength, facilitating the production of lightweight LED displays, and at the same time reducing the installation requirements for application scenarios, with a wide range of applications. The LED display box body of this embodiment includes a rectangular frame, where one side of the rectangular frame is a connection surface and the other side is an installation surface, enabling the rectangular frame to carry and install the LED screen module through the installation surface and be fixedly installed at the installation position of the screen through the connection surface. Specifically, at both ends of the load-bearing beam 1 of this embodiment, connection bumps 14 are provided on the side facing the connection surface, and a plurality of connection holes 141 are provided on the connection bumps 14, enabling the rectangular frame to be installed at the display position through the connection bumps 14 and fixed by inserting screws into the connection holes 141, ensuring the stability and safety during the installation and use of the LED display box body.

[0029] Specifically, the rectangular frame of this embodiment includes load-bearing beams 1 symmetrically arranged at the upper and lower ends and side beams 2 arranged on the left and right sides. The ends of the two side beams 2 and the two load-bearing beams 1 are sequentially connected to form a complete rectangular frame. Among them, the load-bearing beam 1 of this embodiment is made of a metal material, having high strength and good load-bearing capacity. By arranging the load-bearing beam 1 made of metal material at the upper and lower ends of the rectangular frame, the pressure received after the rectangular frame is installed can act on the load-bearing beam 1 made of metal material, thus ensuring the stability and durability of the rectangular frame; the side beam 2 of this embodiment is made of a lightweight non-metallic material, specifically a carbon fiber material, which not only retains the necessary strength but also effectively reduces the overall weight of the rectangular frame, thereby reducing the installation requirements of this embodiment in various scenarios and facilitating the production and installation of lightweight LED displays.

[0030] As Figure 3 and Figure 4As shown in the figure, in order to achieve the stable installation of the load-bearing beam 1 and the side beam 2, in this embodiment, vertical connection grooves 11 are provided at the bottoms of both ends of the load-bearing beam 1. The groove structure of the connection groove 11 is adapted to the outer shape structure of the side beam 2, so that the side beam 2 can be inserted into the connection groove 11 to realize the connection with the end of the load-bearing beam 1, and the installation method is convenient. At the same time, the side beam 2 of this embodiment is a tubular structure, and a positioning block 111 adapted to the inner structure of the side beam 2 is provided at the bottom of the connection groove 11. After the end of the side beam 2 is inserted into the connection groove 11, the positioning block 111 at the bottom of the connection groove 11 can be fitted into the tube body of the side beam 2 to lock the side beam 2. At the same time, glue can be filled in the connection groove 11 to bond the side beam 2, which can further enhance the connection strength between the side beam 2 and the load-bearing beam 1, prevent loosening or falling off caused by external forces, and thus ensure the overall stability of the rectangular frame.

[0031] As Figures 1 to 4 shown in the figure, in order to avoid deformation of the rectangular frame due to force and further improve the overall strength and stability of the specific frame, in this embodiment, reinforcing ribs 12 connecting the side beams 2 are symmetrically arranged at the bottoms on both sides of the center of the load-bearing beam 1, so that the load-bearing beam 1 and the side beam 2 can form a triangular structure under the action of the reinforcing ribs 12, thereby ensuring the stability of the connection between the load-bearing beam 1 and the side beam 2. Specifically, the end of the reinforcing rib 12 of this embodiment extends obliquely away from the center of the load-bearing beam 1 and is provided with a connecting portion 13. The bottom surface of the reinforcing rib 12 is connected to the connecting portion 13 to form a triangular stable structure in combination with the reinforcing rib 12 and the load-bearing beam 1.

[0032] Furthermore, fixing holes 131 are formed on the surface of the connecting portion 13 of this embodiment, and screw holes are provided at the positions corresponding to the fixing holes 131 on the back surface of the side beam 2, so that the end of the reinforcing rib 12 can be connected to the side beam 2 by screwing through the fixing holes 131 and the screw holes. The connection method is simple and convenient for production. In addition, a glue groove 132 surrounding the fixing holes 131 is provided on the surface of the connecting portion 13 of this embodiment that fits the back surface of the side beam 2, so that the connecting portion 13 at the end of the reinforcing rib 12 can also be bonded to the surface of the side beam 2 by glue, enriching the connection method, and the two connection methods can be combined to improve the connection strength between the reinforcing rib 12 and the side beam 2.

[0033] As Figures 1 to 4As shown in the figure, in the middle of the load-bearing beam 1 of this embodiment, there is an electrical installation structure 3 protruding towards the inside of the rectangular frame, and an electrical control box 4 is detachably connected between the electrical installation structures 3 of the two load-bearing beams 1. The electrical components used to control the LED display module can be installed between the electrical installation structures 3 of the two load-bearing beams 1 through the electrical control box 4. Thus, the LED display screen box of this embodiment can be equipped with an electrical control system by itself, realizing the integrated setting of the electrical control system and the box body, reducing the complexity of external electrical connections, and improving the convenience of installation and maintenance. At the same time, for an LED display screen that already has a corresponding position for installing electrical components, the electrical control box can be disassembled, thereby further reducing the overall weight of the box body of this embodiment and further realizing lightweight setting.

[0034] Specifically, on the side of the electrical installation structure 3 facing the connection surface, there is a wire-passing opening 31, and on both sides of the wire-passing opening 31, there are installation blocks 32 extending towards the inside of the rectangular frame. The projection surface of the installation block 32 is an "L"-shaped structure. One end of the installation block 32 is parallel to the connection surface, and the other end is perpendicular to the connection surface, so that the installation block 32 can form an "L"-shaped installation position on one side of the connection surface. The installation positions of the two installation blocks 32 are combined to form an installation groove 33 on one side of the connection surface of the rectangular frame. The two ends of the electrical control box 4 can be respectively fitted into the installation grooves 33 on the upper and lower sides of the rectangular frame to realize the connection with the rectangular frame, which not only realizes the stable installation of the electrical control box 4 but also facilitates the maintenance and replacement of the electrical control system.

[0035] As Figure 2 、 Figure 3 and Figure 4 shown, in order to facilitate the electrical connection between the LED display screen boxes and realize the unified control of the screen modules on each rectangular frame, a wire-passing channel 15 running through both ends of the load-bearing beam 1 is provided inside the load-bearing beam 1 of this embodiment. The wire-passing opening 31 on the electrical installation structure 3 is communicated with the wire-passing channel 15 and is also communicated with the inside of the electrical control box 4. Thus, the wire harness inside the electrical control box 4 can pass through the wire-passing opening 31 into the wire-passing channel 15 and be connected to external devices or adjacent LED display screen boxes through both ends of the load-bearing beam 1, facilitating the layout of electrical lines and protecting the electrical lines at the same time.

[0036] As Figure 2 and Figure 3 shown, on the electrical installation structure 3 of this embodiment, there is also a cover plate 5 that covers the wire-passing opening 31 and is connected to the end of the electrical control box 4, so that the wire harness passing through the wire-passing opening 31 from the electrical control box 4 into the wire-passing channel 15 can be protected by the cover plate 5.

[0037] As Figure 4 and Figure 5As shown in the figure, the electrical control box 4 of this embodiment includes a bottom plate 41 and a box cover 42 covering the bottom plate 41. The PCB board of the control component can be fixedly installed on the bottom plate 41 and locked in a closed space by the box cover 42, so as to protect the PCB board. On the surface of the bottom plate 41 of this embodiment, there are plug through holes for electrical connection with the screen module, so that the connecting wire harness of the screen module can be connected to the PCB board through the plug through holes, and the connection method is convenient.

[0038] The bottom plate 41 and the box cover 42 of this embodiment are fixedly connected by screws. In order to install the electrical control box 4, extended installation parts 421 are provided on both sides of the end of the box cover 42 of this embodiment. When the electrical control box 4 is installed, the installation parts 421 on both sides of the box cover 42 can be fitted at the installation positions of the installation blocks 32 and locked by screws, so as to realize the stable installation of the electrical control box 4. Moreover, a horizontally arranged rib 321 is connected between the two installation blocks 32 of the electrical installation structure 3 of this embodiment. The two ends of the bottom plate 41 can respectively abut against the upper and lower ribs 321 of the rectangular frame, so that the bottom plate 41 is fitted and installed between the two ribs 321, thus realizing the double fixation of the bottom plate 41 and the box cover 42, enabling the electrical control box 4 to be stably installed and facilitating disassembly and maintenance, ensuring the reliability and operability of the electrical control box 4.

[0039] As Figure 5 shown in the figure, end caps 43 are also provided at both ends of the box cover 42 of this embodiment, which can enclose the internal space of the electrical control box 4 to prevent dust, sundries, etc. from entering the electrical control box 4 and affecting the normal operation of the internal electrical components. A wire passing port 431 is provided on the end cap 43 of this embodiment, so that the wire harness can pass through the wire passing port 431 and be laid into the wire passing channel 15.

[0040] In summary, the working principle of this embodiment is as follows: In this embodiment, a rectangular frame is formed by combining the load-bearing beam 1 made of metal material and the side beam 2 made of lightweight non-metallic material, reducing the metal amount of the rectangular frame, thus effectively reducing the overall weight of the display screen box body, facilitating the production of lightweight LED display screens, and reducing the installation requirements of the application scenario. Moreover, the load-bearing beam 1 made of metal material is arranged at the upper and lower ends to ensure the overall strength of the rectangular frame. At the same time, through the electrical installation structure 3 provided in the middle of the load-bearing beam 1, the electrical control box 4 can be connected between the two load-bearing beams 1 through the electrical installation structure 3, so that the display screen box body can be equipped with an electrical control system by itself, realizing the integrated setting of the electrical control system and the box body, reducing the complexity of external electrical connections, and facilitating the installation and maintenance of the LED display screen.
