Description

Technical Field

[0001] The utility model relates to the technical field of LED screens, in particular to a waterproof LED screen structure. Background Art

[0002] LED screens are usually used in indoor and outdoor large billboards, stage backgrounds, stadiums and other occasions, so they need to be waterproof to cope with various weather conditions, such as rain, moisture, snow, etc. If the LED screens are not well waterproof, they may be damaged or short-circuited in rainy and humid environments, thus affecting the life of the equipment and the use effect. The waterproof structure can ensure that the LED screen can still work normally in humid or rainy conditions, thereby ensuring the display effect and user experience. Combined with the shell structure of the LED screen in the existing literature (CN219068554U adopts the technical solution of the utility model to improve the structural stability of the LED screen shell and ensure the waterproof performance of the LED screen shell), it can be seen that at least the following defects are exposed during use:

[0003] 1. Today's waterproof LED screen structures are usually very well sealed, and can effectively prevent external rainwater from entering the LED screen. However, the fully sealed waterproof LED screen structure will also reduce the heat dissipation performance accordingly. Opening ventilation holes for heat dissipation will in turn affect the waterproof effect. Therefore, a waterproof LED screen is needed that can ensure waterproof capabilities while improving heat dissipation capabilities.

[0004] 2. LED screens are usually installed outdoors. The outdoor environment is prone to severe weather, strong winds, splashes, etc., which can easily cause damage to the waterproof LED screen structure. Therefore, a waterproof LED screen structure with better impact resistance is needed. Utility Model Content

[0005] The purpose of the utility model is to provide a waterproof LED screen structure to solve the problems of the existing waterproof LED screen structure during use proposed in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A waterproof LED screen structure comprises a frame, a mounting block is fixedly mounted at the rear end thereof; a heat-conducting shell is fixedly mounted on the surface of the mounting block and completely covers the mounting block; a storage box is mounted inside the mounting block and the area of ​​the storage box is the same as the area inside the mounting block; phase change wax is arranged inside the storage box; an anti-collision shell is fixedly mounted on the upper end of the frame and the anti-collision shell is fixedly mounted on the four ends of the frame, namely, the upper, lower, left and right ends; and a transparent anti-collision layer is fixedly mounted on the front end of the frame and the area of ​​the transparent anti-collision layer is the same as the area of ​​the front end of the frame.

[0008] Preferably, a screen is fixedly mounted on the front end of the frame, and the area of ​​the screen is the same as the area of ​​the front end of the mounting block.

[0009] Preferably, the four front corners of the frame are provided with threaded holes, and the four front corners of the transparent anti-collision layer are also provided with threaded holes.

[0010] Preferably, the volume of the phase change wax is the same as the internal volume of the storage box, and the storage box is connected to the heat conductive shell.

[0011] Preferably, the internal space of the mounting block is communicated with the internal space of the frame, and the mounting block and the internal space of the frame are at the same height.

[0012] Preferably, an anti-collision shell is fixedly installed at the rear end of the frame, and the anti-collision shell is connected to the heat-conducting shell.

[0013] Preferably, the four corners of the front end of the transparent anti-collision layer are threadedly connected with bolts, and the bolts match the threaded holes.

[0014] The present invention provides a waterproof LED screen structure, which has the following beneficial effects:

[0015] 1. By setting up a thermal conductive shell, a storage box, and phase change wax, the waterproof LED screen structure can improve the heat dissipation capacity while ensuring waterproof ability. Under normal circumstances, the thermal conductive shell made of polytetrafluoroethylene assists the LED screen in heat dissipation. In hot weather, when heat accumulates inside the LED screen, the phase change wax absorbs the heat through the storage box, undergoes phase change, and reduces the surrounding temperature. Moreover, since it absorbs heat, there is no need to open holes in the waterproof LED screen structure, thus ensuring its waterproof ability.

[0016] 2. By setting an anti-collision shell around the frame and a transparent anti-collision layer at the front end of the frame, the waterproof LED screen structure has a stronger impact resistance. The anti-collision shell can protect the periphery of the frame to prevent objects falling from above from damaging the frame. The transparent anti-collision layer protects the screen and can be disassembled and assembled through bolts and threaded holes. The transparent anti-collision layer can prevent the screen from being damaged. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0024] Example: Figure 1-3 As shown, a waterproof LED screen structure includes a frame 1, a mounting block 2 is fixedly installed at the rear end of the frame 1, a heat-conducting shell 5 for assisting heat conduction is fixedly installed on the surface of the mounting block 2, a storage box 6 is installed inside the mounting block 2, and a phase change wax 7 for absorbing heat for cooling is arranged inside the storage box 6, and the storage box 6 is connected to the heat-conducting shell 5. In normal weather, the heat-conducting shell 5 assists the LED screen in dissipating heat. In hot weather, the external temperature is high, so that the heat accumulates inside the LED screen, and the phase change wax 7 quickly absorbs a large amount of heat through the storage box 6 and undergoes a phase change from solid to liquid to reduce the temperature. The internal temperature of the mounting block 2 is connected with the interior of the frame 1, so that the internal temperature of the frame 1 is reduced, and the phase change wax 7 absorbs heat. There is no need to open holes on the surface of the mounting block 2, which will not affect the waterproof effect. The thermal conductive shell 5 is polytetrafluoroethylene: polytetrafluoroethylene is a material with excellent high temperature resistance, corrosion resistance and waterproof properties. It can effectively prevent rainwater from penetrating while dissipating heat. The phase change wax 7 is capric acid: capric acid is a common melting phase change wax 7, and its phase change temperature is usually between 50-70 degrees Celsius. It has a high heat capacity and good thermal conductivity, and can effectively absorb and release heat.

[0025] like Figure 2 , 4As shown, a screen 3 is fixedly installed at the front end of the frame 1, a transparent anti-collision layer 9 for protecting the screen is fixedly installed at the front end of the frame 1, an anti-collision shell 8 is fixedly installed at the four ends of the frame 1, threaded holes 10 are arranged at the four corners of the front end of the frame 1 and the transparent anti-collision layer 9, and the threaded holes 10 match the bolts 4. When the waterproof LED screen structure is used, the anti-collision shell 8 prevents objects falling from above from damaging the frame 1, and the transparent anti-collision layer 9 protects the screen 3 to prevent the screen 3 from being damaged by splashes and the like. The transparent anti-collision layer 9 is installed with the frame 1 by bolts 4. When the transparent anti-collision layer 9 needs to be replaced, the bolts 4 can be unscrewed, and the operation is simple. The anti-collision shell 8 is a carbon fiber composite material: the carbon fiber composite material is composed of carbon fiber and a resin matrix, has excellent impact resistance and strength, and also has good waterproof performance; the transparent anti-collision layer 9 is polycarbonate: polycarbonate is a high-strength, impact-resistant transparent plastic material, and also has good waterproof performance.

[0026] Working principle: In normal weather, the heat-conducting shell 5 assists the LED screen in dissipating heat. In hot weather, the external temperature is high, causing heat to accumulate inside the LED screen. The phase change wax 7 quickly absorbs a large amount of heat through the storage box 6 and undergoes a phase change from solid to liquid to reduce the internal temperature of the mounting block 2. The interior of the mounting block 2 is connected to the interior of the frame 1, so that the internal temperature of the frame 1 is reduced. In order for the phase change wax 7 to absorb heat, no holes need to be opened on the surface of the mounting block 2, and the waterproof effect will not be affected. When using the waterproof LED screen structure, the anti-collision shell 8 prevents objects falling from above from damaging the frame 1, and the transparent anti-collision layer 9 protects the screen 3 to prevent the screen 3 from being damaged by splashes and the like. The transparent anti-collision layer 9 is installed with the frame 1 by bolts 4. When the transparent anti-collision layer 9 needs to be replaced, just unscrew the bolts 4, which is simple to operate.
