[0028] Embodiment 1

[0029] As Figures 1-4 shown, an arc-shaped LED display screen installation box for installing an external arc-shaped LED display module includes a load-bearing arc beam 1 for installing at both ends of the arc-shaped LED display module, and a forming connecting beam 2 fixedly connected to both ends of the load-bearing arc beam 1 and located on both sides of the arc-shaped LED display module.

[0030] The load-bearing arc beam 1 includes a first load-bearing arc beam 11 and a second load-bearing arc beam 12, preferably a die-cast aluminum formed part, which is formed by mechanical processing and then surface spraying; the forming connecting beam 2 includes a first forming connecting beam 21 and a second forming connecting beam 22. The first load-bearing arc beam 11, the second load-bearing arc beam 12, the first forming connecting beam 21, and the second forming connecting beam 22 form a square frame. The lengths of the first forming connecting beam 21 and the second forming connecting beam 22 are similar to or the same as the length of the LED display module. The first load-bearing arc beam 11 and the second load-bearing arc beam 12 are respectively located at both ends in the length direction of the LED display module. The load-bearing arc beam 1 is preferably provided with threaded holes for connecting with external installation structure members (structure members for installing the entire installation box, such as walls, large metal brackets). After connecting the entire installation box to the external installation structure members through these threaded holes, the force of the installation box can be transmitted to the external installation structure members.

[0031] The load-bearing arc beam 1 is integrally formed of a metal material. It is preferably an aluminum extrusion part, which is put into use after surface oxidation treatment. One side of it is provided with a U-shaped or V-shaped opening groove 13, and several partition reinforcing ribs 17 are arranged in the opening groove 13. The several partition reinforcing ribs 17 are evenly distributed in the direction parallel to the formed connecting beam and are attached to the inner wall of the opening groove 13.

[0032] At the edge of the opening groove 13, there is a flanging part 14 for fixing the arc-shaped LED display module. The flanging part 14 is arc-shaped and its curvature is the same as that of the installed arc-shaped LED display module. Thus, when the external arc-shaped LED display module is installed at the flanging part 14, the two are closely attached. The flanging part 14 is provided with a connecting structure for fixedly connecting with the arc-shaped display module. The specific connecting structure can be several threaded holes, and the arc-shaped display module is fixedly connected with the outside by bolts passing through the positioning holes, so as to lock and fix the arc-shaped display module on the load-bearing arc beam 1.

[0033] The formed connecting beam 2 includes an installation hollow tube 23 and a wire routing hollow tube 24 integrally formed of a metal material (it should be noted here that the formed connecting beam 2 can also be provided with only one hollow tube for wire routing. Considering factors such as simple forming, production cost, installation stability, and convenient wire routing, it is preferably provided with two parts of hollow tubes), and the installation hollow tube 23 and the wire routing hollow tube 24 form an L-shaped support step 25. The two ends of the formed connecting beam 2 are respectively fixedly connected to the first load-bearing arc beam 11 and the second load-bearing arc beam 12. A control chamber 3 is provided at the middle position of the formed connecting beam 2 and at the L-shaped support step 25. The installation hollow tube 23 is mainly used for fixedly connecting with the load-bearing arc beam 1, so the contact parts at both ends of it with the load-bearing arc beam 1 are preferably flat structures.

[0034] Preferably, connecting members 15 are provided at both ends of the load-bearing arc beam 1. The connecting members 15 are formed with installation parts 151 adapted to the shapes of the corresponding ends of the formed connecting beam 2. The ends of the formed connecting beam 2 are embedded at the installation parts 151 to form a fixed connection. After the formed connecting beam 2 is inserted into the connecting members 15, it is locked by screws, and then the load-bearing arc beam 1 and the formed connecting beam 2 are fixedly connected by welding.

[0035] End openings 16 are also provided at both ends of the load-bearing arc beam 1. The end openings 16, the opening groove 13, and the hollow channels of the wire routing hollow tube 24 are all communicated. The wire harness can pass through the end openings 16, the opening groove 13, and the hollow channels of the wire routing hollow tube 24 to realize the connection of the wire harness and avoid the messy situation of wire harness installation.

[0036] The control bin 3 includes a bottom bin housing 31 and a bin housing 32. The bin housing 32 is preferably an aluminum drawing part and is put into use after surface oxidation treatment. On one side of the bottom bin housing 31 facing the LED display module, there is an arc surface part 311 with the same curvature as the external LED display module. The bottom bin housing 31 and the bin housing 32 together form a receiving space for placing electrical components (especially power supplies and PCB boards). The bottom bin housing 31 is provided with studs for fixing the power supply and the PCB board. On both sides at the two ends of the bottom bin housing 31, there are also wire harness through holes 312. After the wire harness passes through the wire harness through holes 312 and a waterproof ring is fixedly installed, it is electrically connected to the power supply and the PCB board fixed in the bottom bin housing 31 to realize the driving display of the LED display module.

[0037] On both sides of the bottom bin housing 31 corresponding to the load-bearing arc beam 1, the arc surface part 311 is provided with installation bone positions 3111 for fixedly connecting with the external LED display module. The installation bone positions 3111 can be bolt holes or / and positioning column installation holes. Through the installation bone positions 3111, the fixed installation of the control bin 3 and the LED display module is realized. The arc curvatures of the arc surface part 311, the LED display module, and the load-bearing arc beam 1 are the same, and their centers of curvature coincide.

[0038] On one side of the forming connection beam 2 where the installation hollow tube 23 abuts against the control bin 3, there are first screw through holes and positioning holes. On one side of the wiring hollow tube 24 where it abuts against the control bin 3, there are second screw through holes. On the bottom bin housing 31, there are nut holes corresponding to the first screw holes and the second screw hole positions of the forming connection beam 2, and positioning columns corresponding to the positioning holes. When the control bin 3 and the forming connection beam 2 are locked and installed, after the positioning column arranged on the control bin 3 is inserted into the positioning hole of the forming connection beam 2, then the screw passes through the first screw through hole and the second screw through hole to install and lock the control bin 3 on the forming connection beam 2.

[0039] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention belong to the scope of protection required by the present invention.
