[0022] Example

[0023] like Figure 1-3 As shown, this embodiment provides a lightweight folding screen for highways, including two display screens, which are hinged to each other. In this embodiment, the two display screens are arranged side by side, and the connection is connected by a hinge structure 4, so as to achieve a folding effect. When installed, it can be folded at a certain angle and can also be unfolded into a plane for installation.

[0024] Among them, the display screen body includes a control box and multiple display bar modules 1, the multiple display bar modules 1 are arranged in parallel and fixed by a fixing plate 3, wherein the display bar modules 1 leave a certain gap between each other, and the control box 2 is installed on the back side of the multiple display bar modules 1 by bolts. The control box 2 is connected to the display bar module 1 through a wire to realize power supply and communication, and controls the display light bar 12 module to work.

[0025] Specifically, the display bar module 1 includes an aluminum alloy shell 11 and a display light bar 12. The aluminum alloy material has a low density but relatively high strength and good thermal conductivity. One end of the aluminum alloy box body is opened to facilitate the emission of light from the internal display light bar 12. The display light bar 12 is embedded in the aluminum alloy shell 11 and then fixed by filling soft glue. The soft glue can be made of soft glue with good thermal conductivity, which is convenient for conducting the heat of the display light bar 12 and improving the heat dissipation performance. It is matched with the aluminum alloy shell 11 for heat dissipation without the need to install an additional cooling fan.

[0026] like Figure 3 As shown, the outer side of the aluminum alloy shell 11 and the two sides adjacent to the other aluminum alloy shells 11 are respectively integrally formed with light blocking strips 13, and the light blocking strips 13 between the two adjacent aluminum alloy shells 11 are staggered. Light is blocked by the two staggered light blocking strips 13 without the need to install an additional light blocking plate. Moreover, a certain gap is left between the light blocking strips 13 and the adjacent aluminum alloy shells 11, so that a ventilation channel exists between the two aluminum alloy shells 11, thereby improving the heat dissipation efficiency.

[0027] Specifically, the control box 2 includes a box body detachably connected to the back side of the display bar module 1, a box cover detachably connected to the surface of the box body, a power supply and an asynchronous control card are respectively arranged inside the box body, the power supply is connected to the asynchronous control card through an internal wire, and the asynchronous control card is electrically connected to the display light bar 12. In this embodiment, the power supply adopts a rechargeable lithium battery, and the asynchronous control card is used to control the display light bar 12 and communicate with an external controller. The asynchronous control card is used for more stable communication, and the display content is not lost when the communication is interrupted or the power is off.

[0028] Furthermore, the two ends of the back side of the display screen are detachably connected with fixing brackets 5, and a plurality of mounting holes are provided on the side of the fixing bracket 5. The fixing brackets 5 can be installed on the crossbeam of the door frame by connecting the pipe clamps through the mounting holes of the fixing brackets 5. In this embodiment, the fixing brackets 5 on both sides are an integrated sheet metal structure. At this time, the installed folding screen is unfolded and arranged. If folding installation is required, it can be installed through the foldable fixing brackets 5.

[0029] Furthermore, a flashing light control box 6 is fixedly connected to the bottom of the fixing bracket 5, and at least one group of flashing lights 61 is embedded on the surface of the flashing light control box 6, and each group of flashing lights includes a red flashing light 61 and a blue flashing light 61. In this embodiment, there are two groups of flashing lights 61, and the two groups of flashing lights 61 are used to remind the driver and improve the warning effect.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present disclosure.
