Description
Technical Field
The utility model relates to the technical field of display screens, in particular to an LED display screen.
Background
In the field of large-scale LED display screens, an LED display screen is formed in an assembled mode. First, a few conceptual descriptions are presented to make the technical solution more clear.
The unit box body comprises a box body, a display module, a power supply, a system and the like.
The screen body is formed by assembling a plurality of unit box bodies.
The assembled structure is an integral body formed by a plurality of installation structural members such as a steel structure, a hanging beam, a ground beam and the like outside the screen body.
The LED display screen is formed by a screen body and an assembling structure.
At present, most of unit boxes of LED display screens are designed by using boxes to assemble display modules, power supplies and system cards into a whole machine, and the boxes are used as carriers for assembling the display modules, the power supplies, the system cards and the like, and are also provided with structural designs such as positioning, locking and the like.
Therefore, when the unit box body is used for assembling the LED display screen, the assembling of the box bodies and the assembling of the box body and the assembling structure complement each other. In the process of assembling the LED display screen, the requirement of the display screen modeling is realized by the splicing of the box bodies, and the assembling structure not only meets the installation strength and the stability of the screen body installation, but also needs to be matched with the modeling to be processed and assembled.
Namely, the assembly of the box body is the core of the display screen modeling, and the assembly structure is auxiliary. The assembled structure is a main body in the aspect of integral strength, and a screen body assembled by the box body is also important.
For example, an LED arc display screen needs to be assembled, firstly, according to application occasions, an assembly structure is welded according to modeling, then a box body is connected and fixed according to the modeling and the assembly structure, and meanwhile, the box body and the box body need to be connected and fixed.
After the screen body is formed by assembling the plurality of unit box bodies, the power lines and the signal lines between the box bodies are connected, and the power input, the signal input and the like of the screen body are realized, so that the screen body is assembled when the screen body is assembled, and the screen body is assembled except for the assembly structure.
The assembly structure needs better strength to support the whole screen body, and the box body also needs better strength, so that the box body needs more strength redundancy in design by the screen assembly method. For example, when the seat is installed, the bottom row of boxes needs to bear the extrusion force of the whole screen weight, and when the seat is lifted, the top row of boxes needs to bear the pulling force of the whole screen weight. The design of the tank then requires calculation of the strength according to the limit values used, which is redundant for most tanks.
On the assembly, not only the assembly structure is required to be manufactured and installed, but also the connection structure is required to be designed between the box bodies. Therefore, the assembled structural design of the whole large screen system is complex, and the practical application and operation are complex.
