[0029] In this embodiment, the appearance of the display screen body 1 is designed to be different shapes, which are designed according to the installation point. The special-shaped appearance is convenient for installation at different positions of the car shell. The mounting frame 2 is fixed to the outer surface of the display screen body 1. The mounting frame 2 is used to install the display screen body 1. The carbon fiber mounting frame A201 and the carbon fiber mounting frame B202 of the mounting frame 2 are attached to the two sides of the installation point of the car shell, and are fixed by fixing screws 203 to ensure the stability of the installation and prevent it from falling off.

[0030] In this embodiment, the wiring port 104 is internally designed with a wiring terminal, which uses a wire to transmit electrical signals to the light-emitting module 102. The LED display board 302 is electrically connected to the light-emitting module 102, and text, pictures and video information are displayed on the LED display board 302 through the light-emitting module 102.

[0031] In this embodiment, the tempered film protection screen 304 is adhered to the LED display board 302 by high-strength adhesive to protect the LED display board 302 , and the outer side of the tempered film protection screen 304 is fixed to the anti-cracking outer frame 303 .

[0032] In this embodiment, the earthquake-resistant installation frame 301 and the anti-cracking outer frame 303 are both carbon fiber composite material frames, and the anti-cracking outer frame 303 and the earthquake-resistant installation frame 301 are fixed with waterproof sealant.

[0033] Specifically, carbon fiber is a special fiber mainly composed of carbon elements, and its carbon content varies with different types, generally more than 90%. Carbon fiber has the characteristics of general carbon materials, such as high temperature resistance, friction resistance, electrical conductivity, thermal conductivity and corrosion resistance, etc. Its specific gravity is less than 1 / 4 of steel. The tensile strength of carbon fiber resin composite materials is generally above 3500Mpa, which is 7-9 times that of steel, and the tensile elastic modulus is 23000-43000Mpa, which is also higher than steel. Therefore, the specific strength of CFRP, that is, the ratio of the strength of the material to its density, can reach more than 2000Mpa / (g / cm3), while the specific strength of A3 steel is only about 59Mpa / (g / cm3), and its specific modulus is also higher than that of steel, which ensures that the display screen can display information on the outer surface of the car, and can also adapt to the harsh ring formation, so that the display screen has the advantages of high strength, high adaptability and high stability.

[0034] In this embodiment, the display screen used to cover the vehicle body shell is intelligently controlled by a multi-display screen control system, wherein the control system includes a processor module, a display adapter module, an operation module and a network building module;

[0035] The processor module is used to store the text, picture and video information to be displayed. The control interface is written through the web front-end software. The control interface is displayed in the operation module through the display adapter module. The processor module is connected to multiple display screens through the network through the network assembly module. The processor module, the display adapter module and the network assembly module are embedded in the operation module. The operation module is specifically a flat panel display. A network transmission module is installed inside the display screen body 1. Different display screen bodies 1 are set with different network addresses, and different display screen bodies 1 are distinguished by the network addresses.

[0036] In this embodiment, the processor module is data-connected with the display adapter module, the operation module and the network assembly module respectively through pin wires. The operation module and the multiple display screens are connected to the 4G / 5G network through the network assembly module. By setting different network addresses for different display screens, the network addresses of different display screens are obtained during intelligent control, and the data to be displayed is sent to the display screen with the corresponding network address for display. The operation is simple, and multiple display screens can be controlled at the same time, allowing multiple display screens to display the same or different content at the same time, which is more convenient and quick when controlling a large range of display screens.

[0037] Specifically, the processor module is the final execution unit for information processing and program running. Since its creation, the CPU has made great progress in logical structure, operating efficiency and functional extension. The network assembly module is assembled using the network address, which is the logical address of the node on the Internet in the network, which can address the node. The IP address is the way to address the host on the Internet, assigning a logical address to each computer, which can not only identify the computer, but also share information.

[0038] In summary, the present invention as a whole will be adapted to the main body 1 designed to be special-shaped, can be installed in different positions of the car shell, the shape design is carried out according to the installation area, and a carbon fiber installation frame, an anti-seismic installation frame 301 and an anti-cracking outer frame 303 are used, which are hard and wear-resistant to ensure that the car can withstand the impact of road gravel and no scratches or cracks are generated when the car body is scrubbed during driving. The display screen needs to have good weather resistance and will not lose gloss or discolor or crack after long-term exposure to the sun. The protective screen 3 adopts a fully sealed structure, which does not change color or gloss in a humid environment, does not change color or lose gloss when exposed to air with high relative humidity, and has strong corrosion resistance. The tempered film protective screen 304 can be broken into pieces but not scattered when impacted, thereby minimizing damage to passengers. The outer frame is multi-layered. It uses carbon fiber material, which is resistant to high and low temperatures and can work normally within the temperature range of -20 degrees and 55 degrees. Through the operating system, multiple display screens are connected together through network data for control. The specified text, picture and video information can be displayed on the specified display screen on the operation module. Multiple display screens can be intelligently controlled at the same time to ensure that the display screens can be controlled over a large range to improve the convenience of operation. It solves the problem that the current on-board LED display screens on the market do not have the effect of interoperability. One operating system can only control one corresponding display screen. When different screens are projected on different screens, the information needs to be transmitted to different display operating systems for projection. The process is complicated and is not convenient for large-scale projection of text, pictures and video information.
