[0030] As Figure 1 and Figure 2 As shown, the connection structure of this embodiment is used to connect the LED display screen 101 and the installation frame 102. The connection structure includes: a first connection part 10 and a connection body 20. The first end of the connection body 20 is connected to the first connection part 10. The connection body 20 includes a first connecting member 21 and a second connecting member 22. The distance between the first end of the first connecting member 21 and the first end of the second connecting member 22 is less than the distance between the second end of the first connecting member 21 and the second end of the second connecting member 22. Wherein, the first connection part 10 is connected to the LED display screen 101, and the second end of the connection body 20 is connected to the installation frame 102, or the first connection part 10 is connected to the installation frame 102, and the second end of the connection body 20 is connected to the LED display screen 101.

[0031] Applying the technical solution of this embodiment, the connection structure is used to connect the LED display screen 101 and the installation frame 102. The first connection part 10 is connected between the first end of the connection main body 20 and the LED display screen 101, and the second end of the connection main body 20 is connected to the installation frame 102. Or, the first connection part 10 is connected between the first end of the connection main body 20 and the installation frame 102, and the second end of the connection main body 20 is connected to the LED display screen 101. The connection main body 20 includes a first connection member 21 and a second connection member 22, and the distance between the first end of the first connection member 21 and the first end of the second connection member 22 is less than the distance between the second end of the first connection member 21 and the second end of the second connection member 22. Through the above settings, the first connection part 10 can be connected to the LED display screen 101 or to the installation frame 102. When the first connection part 10 is connected to the LED display screen 101, the second end of the connection main body 20 is connected to the installation frame 102. When the first connection part 10 is connected to the installation frame 102, the second end of the connection main body 20 is connected to the LED display screen 101. That is, both of the above two connection methods can enable the connection structure to connect the LED display screen 101 and the installation frame 102. The distance between the first end of the first connection member 21 and the first end of the second connection member 22 is less than the distance between the second end of the first connection member 21 and the second end of the second connection member 22, so that the second end of the connection main body 20 can be connected to the installation frame 102 through the first connection member 21, or the second end of the connection main body 20 can be connected to the installation frame 102 through the second connection member 22, or the second end of the connection main body 20 is connected to the installation frame 102 through the first connection member 21 and the second connection member 22 at the same time. Similarly, the second end of the connection main body 20 can be connected to the LED display screen 101 through the first connection member 21, or the second end of the connection main body 20 can be connected to the LED display screen 101 through the second connection member 22, or the second end of the connection main body 20 is connected to the LED display screen 101 through the first connection member 21 and the second connection member 22 at the same time. That is, the connection main body 20 has multiple connection positions, thereby making the versatility of the connection structure better. Therefore, the technical solution of this embodiment effectively solves the problem of poor versatility of the connection device in the related art.

[0032] It should be noted that the first connection part 10 includes a first mounting plate.

[0033] As Figure 1 shown, in this embodiment, the first connection member 21 includes a first main body part 211 and a second connection part 212. The first end of the first main body part 211 is connected to the first connection part 10, and the second end of the first main body part 211 is connected to the second connection part 212. The first main body part 211 plays a connecting role between the first connection part 10 and the second connection part 212, so that the first connection part 10 can be connected to the first connection part 10.

[0034] It should be noted that the first main body portion 211 includes a first support plate, and the second connection portion 212 includes a second mounting plate.

[0035] As Figure 2 shown, in this embodiment, the connection structure further includes a first reinforcing member 30, and the first reinforcing member 30 is disposed on the first main body portion 211. The first reinforcing member 30 enables the first main body portion 211 to have better structural strength, so that the connection structure can be more stably connected between the LED display screen 101 and the mounting frame 102.

[0036] It should be noted that the first reinforcing member 30 includes a first reinforcing plate and a groove provided in the middle of the first reinforcing plate. The groove has a first side wall, a bottom wall, and a second side wall arranged in sequence, and there is a third preset angle between the first side wall and the second side wall. The third preset angle is between 90° and 150°, specifically, it can be 90°, 100°, 110°, 120°, 130°, 140°, or 150°. The distance between the bottom wall and the first support plate is greater than 0. The notch of the groove is provided on the side of the first reinforcing plate away from the first support plate.

[0037] As Figure 1 shown, in this embodiment, the first connection portion 10 and the second connection portion 212 are located on the same side of the first main body portion 211. The first end of the first reinforcing member 30 is connected to the second connection portion 212, and the second end of the first reinforcing member 30 is connected to the first connection portion 10. The first connection portion 10 and the second connection portion 212 being located on the same side of the first main body portion 211 enables the first connection portion 10, the second connection portion 212, and the first main body portion 211 to occupy less space. The first reinforcing member 30 makes the connection between the first connection portion 10 and the second connection portion 212 more stable.

[0038] As Figure 1As shown, in this embodiment, the second connecting member 22 includes a second main body portion 221 and a third connecting portion 222. The first end of the second main body portion 221 is connected to the first connecting portion 10, and the second end of the second main body portion 221 is connected to the third connecting portion 222. The connecting structure further includes a second reinforcing member 40, and the second reinforcing member 40 is disposed on the second main body portion 221. The first connecting portion 10 and the third connecting portion 222 are located on the same side of the second main body portion 221. The first end of the second reinforcing member 40 is connected to the third connecting portion 222, and the second end of the second reinforcing member 40 is connected to the first connecting portion 10. The second main body portion 221 can connect the first connecting portion 10 and the third connecting portion 222. The second reinforcing member 40 makes the structural strength of the second main body portion 221 better and also makes the connection between the first connecting portion 10 and the third connecting portion 222 more stable. The first connecting portion 10 and the third connecting portion 222 are located on the same side of the second main body portion 221, that is, the first connecting portion 10, the second connecting portion 212, and the third connecting portion 222 are all located on the same side of the first main body portion 211, so that the connecting body 20 can occupy less space.

[0039] It should be noted that the second main body portion 221 includes a second support plate, and the third connecting portion 222 includes a third mounting plate. A V-shaped structure is formed between the first connecting member 21 and the second connecting member 22. The first end of the first support plate is the first end of the first connecting member 21, and the first end of the second support plate is the first end of the second connecting member 22. The distance between the first end of the first connecting member 21 and the first end of the second connecting member 22 is 0. The second mounting plate is the second end of the first connecting member 21, and the third mounting plate is the second end of the second connecting member 22. The second mounting plate and the third mounting plate are spaced apart. There is a fourth preset angle between the extending direction of the first support plate and the extending direction of the second support plate. The fourth preset angle is between 10° and 90°, specifically, it can be 10°, 30°, 45°, 60°, 75°, 80°, or 90°.

[0040] The first connecting member 21 and the second connecting member 22 of this embodiment can be alternatively connected to the mounting frame 102, that is, the connecting body 20 of this embodiment can achieve "one thing for two uses" above and below the equator line.

[0041] Specifically, the structure of the second reinforcing member 40 is the same as the structure of the first reinforcing member 30. The extending direction of the first reinforcing member 30 is the same as the extending direction of the first support plate, and the extending direction of the second reinforcing member 40 is the same as the extending direction of the second support plate. There is an arc transition between the first support plate and the first mounting plate, and there is also an arc transition between the second support plate and the first mounting plate. There is an arc transition between the side where the first support plate and the second support plate are connected and the side where the second support plate and the first support plate are connected.

[0042] In the prior art, the traditional spherical LED display screen is fixed by using flat sheet metal bending parts to fix with the large aluminum plate at the rear. When taking a single part of the sphere, this part will lose the surrounding extrusion pressure of the complete spherical structure. And the center of gravity of this part seriously deviates from the product body, so stronger structural parts are required to fix with the peripheral structure. The original flat sheet metal parts used are relatively long, resulting in insufficient strength and unable to play the role of fixing the screen body. At the same time, the hooks of this sheet metal part face outward and extend about 30 mm beyond the edge of the screen body, seriously affecting the display effect. Moreover, the long iron hooks easily cause the screen body to shake and have poor strength.

[0043] The connecting body 20 of this embodiment uses sheet metal bending with a thickness of 3 mm, and under the action of the first reinforcing member 30 and the second reinforcing member 40, the structural strength can be increased by at least 2 times compared with the sheet metal parts in the prior art.

[0044] As Figure 3 、 Figure 5 and Figure 6 shown, the LED display device of this embodiment includes an LED display module 100. The LED display module 100 includes an LED display screen 101, a mounting frame 102 connected to the LED display screen 101, and a connecting structure disposed between the LED display screen 101 and the mounting frame 102. The connecting structure is the above-mentioned connecting structure. The side of the connecting structure facing the outside of the LED display screen 101 is flush with the edge of the LED display screen 101 or located inside the LED display screen 101. When the above-mentioned connecting structure is in use, the second end of the connecting body 20 can be connected to the mounting frame 102 through the first connecting member 21, or the second end of the connecting body 20 can be connected to the mounting frame 102 through the second connecting member 22, or the second end of the connecting body 20 is connected to the mounting frame 102 through the first connecting member 21 and the second connecting member 22 at the same time. Similarly, the second end of the connecting body 20 can be connected to the LED display screen 101 through the first connecting member 21, or the second end of the connecting body 20 can be connected to the LED display screen 101 through the second connecting member 22, that is, the connecting body 20 has multiple connection positions, which facilitates the connection of the connecting body 20 to the LED display screen 101, or facilitates the connection of the connecting body 20 to the mounting frame 102, that is, makes the connecting structure have better versatility. The LED display device with the above-mentioned connecting structure also has the above-mentioned advantages. The side of the connecting structure facing the outside of the LED display screen 101 is flush with the edge of the LED display screen 101 or located inside the LED display screen 101, so that when the connecting structure is connected between the LED display screen 101 and the mounting frame 102, the connecting structure will not protrude beyond the edge of the LED display screen 101, thereby making the aesthetics of the LED display device better.

[0045] The display device using the connection structure of this embodiment can make the fixing method of the LED display screen 101 more firm and reliable, and the overall appearance more beautiful.

[0046] As Figure 3 and Figure 4 shown, in this embodiment, the LED display module 100 further includes a third connecting member 103. The first end of the third connecting member 103 is connected to the mounting frame 102, and the second end of the third connecting member 103 is connected to the second end of the first connecting member 21, or the second end of the third connecting member 103 is connected to the second end of the second connecting member 22. The third connecting member 103 can be connected between the mounting frame 102 and the first connecting member 21, or the third connecting member 103 can be connected between the mounting frame 102 and the second connecting member 22. The above two connection methods can both realize the connection between the third connecting member 103 and the connection main body 20. Furthermore, the third connecting member 103 can be connected to the first connecting portion 10 through the connection main body 20.

[0047] Of course, in other embodiments, the second end of the third connecting member 103 is connected to the second end of the first connecting member 21, and the second end of the third connecting member 103 is connected to the second end of the second connecting member 22. This makes the connection between the third connecting member 103 and the connection main body 20 more stable, and further makes the connection between the LED display screen 101 and the mounting frame 102 more stable. The second end of the third connecting member 103 is connected to the second end of the first connecting member 21, and the second end of the third connecting member 103 is connected to the second end of the second connecting member 22 means that the third connecting member 103 can include two. One of the two third connecting members 103 is connected to the first connecting member 21, and the other of the two third connecting members 103 is connected to the second connecting member 22, or the third connecting member 103 includes one, and the second end of the third connecting member 103 is simultaneously connected to the first connecting member 21 and the second connecting member 22.

[0048] As Figure 3 、 Figure 7 and Figure 8As shown, in this embodiment, the third connecting member 103 includes a fourth connecting portion 1031, a fifth connecting portion 1032, and a sixth connecting portion 1033 located between the fourth connecting portion 1031 and the fifth connecting portion 1032. There is a first preset angle between the centerlines of the fourth connecting portion 1031 and the fifth connecting portion 1032. The fourth connecting portion 1031 is connected to the connecting structure, and the fifth connecting portion 1032 is connected to the mounting frame 102. The sixth connecting portion 1033 can connect the fourth connecting portion 1031 and the fifth connecting portion 1032. The fourth connecting portion 1031 enables the third connecting member 103 to be connected to the connecting structure, and the fifth connecting portion 1032 enables the third connecting member 103 to be connected to the mounting frame 102. There is a first preset angle between the centerlines of the fourth connecting portion 1031 and the fifth connecting portion 1032, which facilitates the connection of the third connecting member 103 to the connecting structure and the mounting frame 102.

[0049] It should be noted that the first preset angle is between 80° and 135°. Specifically, it can be 80°, 90°, 110°, 120°, or 135°. In this embodiment, the first preset angle is 90°.

[0050] As Figure 3 and Figure 8 As shown, in this embodiment, the sixth connecting portion 1033 includes a first plate body 10331 and a second plate body 10332 connected to the first plate body 10331. There is a second preset angle between the first plate body 10331 and the second plate body 10332. The fourth connecting portion 1031 is connected to the first plate body 10331 and extends away from the second plate body 10332, and the fifth connecting portion 1032 is connected to the second plate body 10332 and extends away from the first plate body 10331. The first plate body 10331 can connect the fourth connecting portion 1031 and the second plate body 10332, and the second plate body 10332 can connect the fifth connecting portion 1032 and the first plate body 10331. There is a second preset angle between the first plate body 10331 and the second plate body 10332, which enables the sixth connecting portion 1033 to avoid the mounting frame 102 and facilitates the connection of the third connecting member 103 to the LED display screen 101 and the mounting frame 102. The fourth connecting portion 1031 is connected to the first plate body 10331 and extends away from the second plate body 10332, which facilitates the connection of the fourth connecting portion 1031 to the connecting structure, and the fifth connecting portion 1032 is connected to the second plate body 10332 and extends away from the first plate body 10331, which facilitates the connection of the fifth connecting portion 1032 to the mounting frame 102.

[0051] It should be noted that the second preset angle is between 80° and 150°. Specifically, it can be 80°, 90°, 110°, 113°, 120°, 135° or 150°. In this embodiment, the second preset angle is 113°.

[0052] As Figure 3 shown, in this embodiment, the fourth connecting portion 1031 includes a third plate body 10311. The third connecting member 103 further includes a third reinforcing member 1034. The third reinforcing member 1034 is disposed between the first plate body 10331 and the third plate body 10311. The LED display module 100 includes a plurality of them, and the plurality of LED display modules 100 enclose a spherical shape. The third reinforcing member 1034 makes the connection between the first plate body 10331 and the third plate body 10311 more stable, and thus makes the structural strength of the third connecting member 103 better.

[0053] A plurality of U-shaped grooves are provided on the third plate body 10311. The openings of the U-shaped grooves are located on the side of the third plate body 10311 away from the first plate body 10331. The U-shaped grooves extend in the direction from the third plate body 10311 to the first plate body 10331. A plurality of first mounting holes are provided on the second mounting plate, and the plurality of U-shaped grooves are arranged in one-to-one correspondence with the plurality of first mounting holes.
