[0033] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. The description of the at least one exemplary embodiment is merely illustrative, and by no means constitutes any limitation to the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0034] As shown in Figures 1 to 3 , Figure 5 and Figure 6 , the present application provides an LED display box, and the embodiments of the LED display box of the present application include: a frame 10, an LED display module 20, a power box 30, a first sealing ring 40 and a water baffle 50. Wherein, the LED display module 20 is connected to the front side of the frame 10, and the LED display module 20 has a first plug-in part 21; the power box 30 is connected to the rear side of the frame 10, and the power box 30 has a second plug-in part 31 which is plug-in matched with the first plug-in part 21; the first sealing ring 40 is clamped between the LED display module 20 and the power box 30 and is arranged around the outer periphery of the first plug-in part 21 and the second plug-in part 31; the water baffle 50 is arranged on the front surface of the power box 30 and is located above the first sealing ring 40, and the water baffle 50 is abutting matched with the LED display module 20.
[0035] By applying the technical scheme of the present embodiment, the first plug-in part 21 is arranged on the LED display module 20, the second plug-in part 31 which is plug-in matched with the first plug-in part 21 is arranged on the power box 30, and the plug-in matching between the first plug-in part 21 and the second plug-in part 31 can realize the transmission of electric energy and control signals to the LED display module 20. The first sealing ring 40 is arranged around the outer periphery of the first plug-in part 21 and the second plug-in part 31, which realizes the protection of the first plug-in part 21 and the second plug-in part 31. The LED display box further includes the water baffle 50 arranged on the power box 30, and the water baffle 50 is located above the first sealing ring 40 and is abutting matched with the LED display module 20. When the rainfall is large, even if the rainwater flows into the LED display module 20 and the power box 30, the rainwater flowing to the first sealing ring 40 will be blocked by the water baffle 50 first. Most of the rainwater will flow away along the two sides of the water baffle 50, and a small part of the rainwater will seep between the water baffle 50 and the LED display module 20. The amount of this part of rainwater is small, and the flow rate after passing through the water baffle 50 is very low, which will not have a scouring effect on the first sealing ring 40, thereby ensuring the sealing performance of the first sealing ring 40. Therefore, the technical scheme of the present embodiment can effectively solve the problem that the rainwater will scoure the sealing ring structure and affect the sealing effect in the related art.
[0036] It should be noted that the above-mentioned "water baffle 50 is located above the first sealing ring 40" refers to the upper side of the LED display box in the display state, that is Figure 1 and Figure 2 the upper side.
[0037] As shown in Figure 5 and Figure 6 , the water baffle 50 has a top surface 51, and the flatness of the top surface 51 is less than or equal to 0.1mm. The flatness of the top surface 51 is less than or equal to 0.1mm, which can ensure the abutting effect between the top surface 51 and the LED display module 20, thereby ensuring the blocking effect of rainwater, so that most of the rainwater flows away along the two sides of the water baffle 50, and only a small part of the rainwater will penetrate between the water baffle 50 and the LED display module 20 and continue to flow to the first sealing ring 40. Preferably, the flatness of the top surface 51 can be 0.1mm, 0.08mm or 0.05mm.
[0038] In this embodiment, the roughness of the top surface 51 is less than or equal to 10μm. This setting can ensure the abutting effect between the top surface 51 and the LED display module 20, thereby ensuring the blocking effect of rainwater, so that most of the rainwater flows away along the two sides of the water baffle 50, and only a small part of the rainwater will penetrate between the water baffle 50 and the LED display module 20 and continue to flow to the first sealing ring 40. Preferably, the roughness of the top surface 51 can be 10μm, 8μm or 5μm.
[0039] Specifically, in this embodiment, the box body of the power box 30 (i.e. the front box body 32 and the rear box body 33 mentioned below) is formed by injection molding, and after injection molding, the front surface of the water baffle 50 is machined to make the top surface 51 meet the requirements of flatness and roughness. The forming method of the first support rib 61, the second support rib 62 and the third support rib 63 mentioned below is similar to that of the water baffle 50, which will not be described again.
[0040] As shown in Figure 5 and Figure 6 , the LED display box further comprises a first support rib 61 arranged on the side of the first sealing ring 40, which extends in the up-down direction and abuts with the LED display module 20. During the insertion of the first plug-in part 21 and the second plug-in part 31, due to the insertion force, the LED display module 20 will have a tendency to deform, and during the processing and transportation of the LED display module 20, the bottom shell of the LED display module 20 will also deform. The first support rib 61 can provide support for the LED display module 20, and can flatten the bottom shell of the LED display module 20, thereby ensuring the display effect.
