The waterproof ring 60 is arranged between the surrounding wall 30 and the cover 50, so that when the cover 50 is in the blocking position, the waterproof ring 60 can seal the gap between the surrounding wall 30 and the cover 50, preventing water vapor in the external environment from entering the surrounding wall 30 through the gap between the surrounding wall 30 and the cover 50 and corroding the plug-in part 11, that is, the service life of the plug-in part 11 is extended. Therefore, the technical solution of the present application effectively solves the problem of poor waterproof effect at the interface of the LED display wire in the related art.
[0029] Preferably, the waterproof ring 60 is a waterproof silicone sleeve.
[0030] Of course, in an embodiment not shown in the figures, the material of the waterproof ring 60 may also be rubber.
[0031] like Figure 1 and Figure 2 As shown, in this embodiment, the LED display unit further includes a hinge structure 70 and a connection structure 80, which are arranged between the surrounding wall 30 and the cover body 50, and the hinge structure 70 and the connection structure 80 are arranged opposite to each other. The hinge structure 70 facilitates the cover body 50 to swing on the surrounding wall 30, and the connection structure 80 makes the connection between the cover body 50 and the surrounding wall 30 more stable when the cover body 50 is in the blocking position, and also enables the waterproof ring 60 to play a waterproof role between the surrounding wall 30 and the cover body 50.
[0032] like Figures 4 to 6 As shown, in this embodiment, the connection structure 80 includes a clamping structure 81, and the clamping structure 81 includes a clamping arm 811 and a clamping slot 812. The clamping arm 811 is provided with a clamping block 8111 that is clamped and matched with the clamping slot 812. The clamping arm 811 is provided on the cover body 50, and the clamping slot 812 is provided on the outer side wall of the surrounding wall 30. The clamping block 8111 is inserted into the clamping slot 812, so that the clamping arm 811 can be clamped and connected with the clamping slot 812, that is, the clamping slot 812 can limit the clamping arm 811, so that the cover body 50 connected with the clamping arm 811 can be stably in the blocking position, and under the action of the cover body 50, the waterproof ring 60 and the surrounding wall 30, the plug-in portion 11 can be protected. The arrangement of the block 8111 and the slot 812 facilitates the block 8111 to enter the slot 812 and also facilitates the block 8111 to leave the slot 812, thereby making it easier for the cover 50 to move between the blocking position and the open position.
[0033] Specifically, the clamping arm 811 is elastic, so that it is convenient for the clamping block 8111 to enter into or leave the clamping slot 812 .
[0034] like Figures 4 to 6 As shown, in this embodiment, the cover body 50 includes a cover plate 51 and a first flange 52, the first flange 52 is arranged around the edge of the cover plate 51, and the waterproof ring 60 is fixed on the cover plate 51 and located on the inner side of the first flange 52. The cover plate 51 can cover a larger area of the surrounding wall 30, so that the cover body 50 can block the surrounding wall 30 more effectively, and the first flange 52 makes the position of the waterproof ring 60 on the cover plate 51 more stable, and also makes it possible for the waterproof ring 60 to block the gap between the first flange 52 and the surrounding wall 30 when the cover body 50 is covered on the surrounding wall 30, so as to prevent moisture from entering the surrounding wall 30 through the gap between the cover body 50 and the surrounding wall 30.
[0035] like Figure 5 and Figure 6 As shown, in this embodiment, the cover body 50 further includes a convex portion 53, and the hinge structure 70 is disposed between the convex portion 53 and the surrounding wall 30. The arrangement of the convex portion 53 facilitates the connection between the hinge structure 70 and the surrounding wall 30, thereby making it easier for the cover body 50 to swing relative to the surrounding wall 30, i.e., making it easier for the cover body 50 to switch between the blocking position and the open position.
[0036] Preferably, the hinge structure 70 includes a first connecting plate, a second connecting plate and a connecting shaft connected between the first connecting plate and the second connecting plate, the first connecting plate is connected to the protrusion 53, and the second connecting plate is connected to the outer side wall of the surrounding wall 30. The connecting shaft can connect the first connecting plate and the second connecting plate, and also enable the first connecting plate and the second connecting plate to swing around the connecting shaft.
[0037] like Figure 1 and Figure 2As shown, in this embodiment, the surrounding wall 30 includes a body portion 31 and a second convex edge 32. The second convex edge 32 is arranged at the end of the body portion 31 away from the LED display module 10. When the cover body 50 is in the blocking position, the waterproof ring 60 abuts against the second convex edge 32. The body portion 31 allows a gap between the cover body 50 and the rear shell 20, so that the structure connected to the plug-in portion 11 can enter the surrounding wall 30 through the wire groove 40 and connect with the plug-in portion 11. The waterproof ring 60 cooperates with the second convex edge 32, so that when the cover body 50 moves from the open position to the blocking position, under the action of the first convex edge 52, the second convex edge 32 and the waterproof ring 60 arranged between the first convex edge 52 and the second convex edge 32, the gap between the surrounding wall 30 and the cover body 50 can be blocked, so as to prevent moisture in the external environment from entering the surrounding wall 30 and corroding the plug-in portion 11.
[0038] like Figure 5 As shown, in this embodiment, the first flange 52 is arranged around the outer periphery of the second flange 32. The first flange 52 is arranged around the outer periphery of the second flange 32, so that the waterproof ring 60 can effectively seal between the first flange 52 and the second flange 32, preventing water vapor in the external environment from entering the surrounding wall 30 through the gap between the surrounding wall 30 and the cover body 50.
[0039] Preferably, the waterproof ring 60 can be squeezed between the first convex edge 52 and the second convex edge 32, so that the waterproof ring 60 can completely fill the gap between the first convex edge 52 and the second convex edge 32, and then the waterproof ring 60 can effectively play a waterproof role. Figure 5 As shown, in the direction from the cover plate 51 to the LED display module 10, the distance between the inner wall of the first flange 52 and the axis of the surrounding wall 30 gradually increases, so that the cover body 50 can be more easily covered to the surrounding wall 30, and the waterproof ring 60 can be fully deformed between the first flange 52 and the second flange 32 to fill the gap between the first flange 52 and the second flange 32.
[0040] like Figure 1 and Figure 2 As shown, in this embodiment, the surrounding wall 30 and the LED display module 10 are an integrally formed structure. The above arrangement facilitates the molding and manufacturing of the surrounding wall 30 and the LED display module 10, and the production cost is low.
[0041] like Figures 1 to 6As shown, according to another aspect of the utility model, there is provided an LED display device, comprising a housing and a plurality of LED display units connected to the housing, wherein the LED display units are the above-mentioned LED display units. The housing can support the plurality of LED display units, thereby ensuring the normal use of the LED display device. The waterproof ring 60 of the above-mentioned LED display unit can block the gap between the surrounding wall 30 and the cover body 50, so that the moisture in the external environment can be isolated by the waterproof ring 60, thereby preventing the water vapor in the external environment from entering the surrounding wall 30 and corroding the plug-in portion 11. The LED display device having the above-mentioned LED display unit also has the above-mentioned advantages.
[0042] like Figure 1 and Figure 2 As shown, in this embodiment, the LED display device further includes a connecting wire 100 and a waterproof block 110. The waterproof block 110 is sleeved on the connecting wire 100. One end of the connecting wire 100 extends into the surrounding wall 30 through the wire groove 40 and is plugged with the plug-in portion 11. When the connecting wire 100 is inserted into the surrounding wall 30, the waterproof block 110 is located at the wire groove 40. The wire groove 40 allows the connecting wire 100 to enter the surrounding wall 30 more easily, and then the connecting wire 100 can be plugged with the plug-in portion 11, so that the LED display unit can be used normally. The waterproof block 110 can block the wire groove 40 to prevent water vapor in the external environment from entering the surrounding wall 30 through the wire groove 40. The wire groove 40 also allows the connecting wire 100 to be easily taken out of the surrounding wall 30 when it is separated from the plug-in portion 11.
[0043] Specifically, the waterproof ring 60 and the wire groove 40 can isolate the space of the surrounding wall 30 from the external environment, thereby preventing water vapor in the external environment from entering the surrounding wall 30 and corroding the connecting wire 100 and the plug-in part 11 .
[0044] Preferably, the waterproof block 110 includes a main body and a first recess and a second recess arranged on both sides of the main body, the first recess and the second recess abut against the groove wall of the wire groove, and can isolate the water vapor in the external environment.
