In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0036] like Figure 1 and Figure 2As shown, according to one aspect of the present embodiment, there is provided an LED display unit, comprising: a housing 10, a connecting assembly 20, and a light board 30. The connecting assembly 20 comprises a plurality of connecting members 21, which are arranged on the housing 10 at intervals along a first preset direction, each connecting member 21 comprises a rotating portion 211 and a mounting portion 212, and the rotating portion 211 is rotatably connected to the housing 10. The light board 30 is mounted on the housing 10 through the connecting assembly 20, and the light board 30 is connected to the plurality of mounting portions 212 of the connecting assembly 20.

[0037] By applying the technical solution of this embodiment, the connection assembly 20 includes a plurality of connection members 21 arranged on the box 10, and the plurality of connection members 21 are arranged at intervals along the first preset direction. Each connection member 21 includes a rotating portion 211 and a mounting portion 212, and the rotating portion 211 is rotatably connected to the box 10. The light board 30 is on the box, and the connection assembly 20 is connected between the light board 30 and the box 10. The light board 30 is connected to the plurality of mounting portions 212 of the connection assembly 20. Through the above arrangement, the light board 30 is connected to the plurality of mounting portions 212 of the connection assembly 20, and the rotating portion 211 is connected to the box 10, so that the light board 30 can be connected to the box 10 through the connection assembly 20. The plurality of connection members 21 are arranged at intervals on the box 10 along the first preset direction, so that the connection between the light board 30 and the connection assembly 20 is more stable, that is, the connection between the light board 30 and the box 10 is more stable. The rotating part 211 is rotatably connected to the box 10, so that after the light board 30 is connected to the plurality of mounting parts 212, the plurality of mounting parts 212 can be rotated to be flush with the light board 30, thereby preventing the light board 30 from bending when the LED display unit is in use and causing damage to the light board 30. Therefore, the technical solution of this embodiment effectively solves the problem in the related art that when the light bar is installed to the box through the light bar mounting structure, the light bar mounting structure has poor straightness, which causes the light bar to be damaged.

[0038] It should be noted that, under the action of the rotating part 211, the connecting piece 21 can be adjusted to any direction to achieve the desired position of fixing the light board 30. Specifically, the display surface of the LED display unit is a curved spherical surface, the light board 30 is a curved LED light bar, and the display surface of the LED display unit is composed of a number of curved LED light bars. Due to the curved spherical surface of the LED display unit, the LED light bar is made into a curve, and the curved LED light bar has various angles on the spherical surface, so it is very important to fix the light board 30 with a mechanism that can be fixed in any direction. First, install the connecting piece 21 on the vertical plate 132, and then insert a number of curved LED light bars into the mounting part 212, and then buckle them into the corresponding mounting part 212, so that the display surface of the LED display unit is a curved spherical surface. When the rotating part 211 is installed in the mounting hole 111, the limiting hole 31 is inserted between the first limiting block 21211 and the second limiting block 21221, and the direction of the rotating part 211 in the mounting hole 111 can be adjusted arbitrarily, so that the display surface of the LED display unit is a curved spherical surface.

[0039] like Figure 2 and Figure 3 As shown, in this embodiment, the mounting portion 212 includes a first clamping plate 2121 and a second clamping plate 2122 that are arranged opposite to each other, and there is a gap between the first clamping plate 2121 and the second clamping plate 2122, and the light board 30 is inserted between the first clamping plate 2121 and the second clamping plate 2122. There is a gap between the first clamping plate 2121 and the second clamping plate 2122, so that the light board 30 can be inserted between the first clamping plate 2121 and the second clamping plate 2122, and the first clamping plate 2121 and the second clamping plate 2122 can clamp the light board 30, so that the light board 30 can be connected to the box 10.

The plurality of limiting holes 31 arranged at intervals along the length direction of the light board 30 and the plurality of connecting members 21 are arranged in one-to-one correspondence, so that the plurality of connecting members 21 can fix the light board 30 more effectively. The first limit block 21211 and the second limit block 21221 are inserted into the limit hole 31. The first limit block 21211 and the second limit block 21221 can limit the light bar, so that the connection between the first clamping plate 2121, the second clamping plate 2122 and the light board 30 is more stable, which prevents the light board 30 from detaching from the mounting portion 212 after being installed in the mounting portion 212.

[0041] like Figure 2 , Figure 3 as well as Figure 7 As shown, in this embodiment, the connecting member 21 further includes a connecting block 213 located between the rotating portion 211 and the mounting portion 212. When the light board 30 is connected to the mounting portion 212, the connecting block 213 is limitedly matched with the light board 30. The connecting block 213 can limit the distance between the light board 30 and the box 10, so that after the light board 30 is installed, the LED display unit can present a better display effect.

[0042] It should be noted that the two ends of the connecting block 213 are respectively abutted against the lamp board 30 and the vertical plate 132, that is, the connecting block 213 can prevent the mounting portion 212 from passing through the mounting hole 111 and falling off from the mounting hole 111, and also make the connection between the lamp board 30 and the connecting member 21 more stable, and also allow a gap to exist between the lamp board 30 and the vertical plate 132, thereby ensuring heat dissipation of the lamp board when in use.

[0043] like Figure 5 and Fig. 9 As shown, in this embodiment, a mounting hole group 11 is provided on the housing 10, and the mounting hole group 11 includes a plurality of mounting holes 111.

The mounting hole 111 enables the column 2111 to be connected to the housing 10, and then the connector 21 can be connected to the housing 10, that is, the light board 30 is connected to the housing 10. The plurality of mounting holes 111 and the plurality of connectors 21 are arranged one-to-one, so that the connection between the light board 30 and the housing 10 through the connector 21 is more stable.

[0044] like Figure 2 , Figure 3 , Figure 5 , Figure 7 as well as Fig. 9As shown, in this embodiment, a groove 21111 is provided on the side of the column 2111 away from the mounting portion 212, and the rotating portion 211 also includes a third limit block 2112 and a fourth limit block 2113, the third limit block 2112 and the fourth limit block 2113 are both connected to the outer wall of the column 2111, and the third limit block 2112 and the fourth limit block 2113 are located on both sides of the groove 21111. The groove 21111 allows the column 2111 to be inserted into the mounting hole 111. Under the extrusion of the third limit block 2112 and the fourth limit block 2113 and the inner wall of the mounting hole 111, the third limit block 2112 and the fourth limit block 2113 can approach each other, that is, the outer dimensions of the column 2111 can be changed until the third limit block 2112 and the fourth limit block 2113 pass through the mounting hole 111. The third limit block 2112 and the fourth limit block 2113 can limit the column together with the box body, so that the connection between the connecting piece 21 and the box body 10 is more stable.
