[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the following is a summary of the technical problems, technical solutions and beneficial effects to be solved by the present invention. Figure 1-4 It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] Reference Figure 1 , Figure 2 and Figure 3, an LED display screen with a protective function, comprising a screen 1, a protective plate 2 and a driving device 3, wherein the protective plate 2 comprises a cover plate 21, a baffle plate 22 and two side plates 23, one side of the protective plate 2 is rotatably connected to the top of the screen 1, the baffle plate 22 is located on the side of the cover plate 21 away from the screen 1 and is perpendicular to the cover plate 21; the two side plates 23 are located on both sides of the cover plate 21 and are perpendicular to the cover plate 21, and the two sides of the baffle plate 22 are respectively connected to the two side plates 23. The driving device 3 is set as a driving cylinder, the driving cylinder is movably connected to one side of the screen 1, and one end of the telescopic rod of the driving cylinder is movably connected to one side of the cover plate 21, the length dimension of the cover plate 21 is set to "L", and the length dimension of the screen 1 is set to "D", and the relationship between the length dimension of the cover plate 21 and the length dimension of the screen 1 satisfies L>D, so that the cover plate 21 can completely cover the surface of the screen 1.

[0021] When the telescopic rod of the driving cylinder is extended, the driving cover plate 21 is turned to be perpendicular to the screen 1. At this time, the baffle 22 is located below the cover plate 21 and is perpendicular to the screen 1. At this time, the cover plate 21 and the baffle 22 can protect the screen 1 from wind and rain and prevent the screen 1 from being directly exposed to the sun. In order to avoid interference between the side plate 23 and the driving cylinder, a clearance groove 232 is formed at the side plate 23 near the baffle 22. When the telescopic rod of the driving cylinder is retracted, the driving cover plate 21 is covered on the surface of the screen 1. At this time, the baffle 22 abuts against the bottom end of the screen 1, and the side plates 23 on both sides of the cover plate 21 enclose the side of the screen 1. The connection between the driving cylinder and the screen 1 is embedded in the clearance groove 232, so that the cover plate 21 and the baffle 22 protect the screen 1. In order to avoid direct contact between the cover plate 21 and the surface of the screen 1, a protective pad 211 is provided on the surface of the cover plate 21 facing the screen 1, so that the surface of the screen 1 is further protected by the protective pad 211.

[0022] When the cover plate 21 is placed on the surface of the screen 1, in order to prevent rainwater from penetrating through the gap between the side plate 23 and the two side surfaces of the screen 1 when it rains, a sealing gasket 231 is provided on the side of the side plate 23 facing the side surface of the screen 1. The sealing gasket 231 is made of rubber material to ensure that the surface of the sealing gasket 231 fits the side surface of the screen 1. In addition, the protective plate 2 is made of polystyrene material. The protective plate 2 made of polystyrene material is impermeable but has good air permeability. Under the premise of satisfying the heat dissipation of the screen 1, the protective plate 2 has a good rainproof and waterproof effect on the screen 1.

[0023] Reference Figure 2 , Figure 3 and Figure 4In order to realize the rotational connection between the cover plate 21 and the top of the screen 1, a rotating seat 24 is provided on the side of the cover plate 21 away from the baffle 22, and a rotating hole 241 is formed through the side surface of the rotating seat 24, and correspondingly, an axle rod 11 is fixedly provided transversely through the top of the screen 1, and the axle rod 11 is passed through the rotating hole 241 of the rotating seat 24, so as to realize the rotational connection between one side of the cover plate 21 and the screen 1.

[0024] The specific implementation principle of the embodiment of the present application is as follows: when the screen 1 of the LED display needs to be played, the telescopic rod of the driving cylinder is extended to drive the cover plate 21 to flip until the cover plate 21 flips to a state perpendicular to the screen 1, and at the same time, the baffle 22 remains parallel to the screen 1. When it is rainy, the cover plate 21 and the baffle 22 can protect the screen 1 from rain; when it is sunny, the cover plate 21 and the baffle 22 can cover the screen 1 and prevent the sun from directly shining on the surface of the screen 1, thereby protecting the screen 1.

[0025] When the screen 1 of the LED display screen finishes playing, the telescopic rod of the driving cylinder is retracted, thereby driving the cover plate 21 to cover the surface of the screen 1. The surface protection pad 211 of the cover plate 21 is set to avoid direct contact between the cover plate 21 and the screen 1, thereby causing damage to the surface of the screen 1. At this time, the baffle 22 on one side of the cover plate 21 abuts against the bottom of the screen 1, and the side panels 23 on both sides of the cover plate 21 enclose the side surface of the screen 1, and the sealing pad 231 on the side panel 23 fits with the two side surfaces of the screen 1, thereby blocking the gap between the side panel 23 and the side surface of the screen 1, so as to prevent rainwater from penetrating from the gap between the side panel 23 and the side surface of the screen 1 in rainy weather. In this way, the screen 1 of the LED display screen can be protected no matter what state it is in.

[0026] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all protected by the utility model.
