As shown in FIG. 1, the present invention further provides a display screen 10. Referring to FIG. 2 at the same time, the display screen 10 includes a display module 200 and the angle adjusting device 100 of any one of the above embodiments. The number of the display modules 200 is at least two, and two adjacent display modules 200 abut each other. The base 110 is disposed on one of the display modules 200, and the second base 140 is disposed on the other display module 200. The first gear meshing portion 134 of the angle adjusting device 100 provided on one of the display modules 200 and the second gear of the angle adjusting device 100 provided on the other display module 200 are engaged between two adjacent display modules 200. Portion 164 engages the transmission.

In one embodiment, the number of the display modules 200 is N, and the number of the angle adjusting devices 100 is N-1, where N is greater than or equal to two. Each display module 200 is provided with at least one angle adjusting device 100. There are two angle adjustment devices 100 on any display module 200 in the middle of the display screen 10. The first gear meshing portion 134 of one of the angle adjustment devices 100 and the other of the angle adjustment device 100 are located on the same display module 200. The second gear meshing portion 164 meshes with the transmission.

The N display modules 200 abut against each other in order to form the display screen 10. Since two adjacent display modules 200 are always abutted and linked, two angle adjustment devices 100 are provided on any display module 200 in the middle of the display screen 10. The transmission is performed, that is, the first base 110 of one of the angle adjustment devices 100 and the second base 140 of the other angle adjustment device 100 are set on any display module 200 in the middle at the same time. The first gear meshing portion 134 of the angle adjusting device 100 meshes with the second gear meshing portion 164.

When an included angle between two adjacent display modules 200 needs to be adjusted, one of the display modules 200 of the display screen 10 is rotated, and the rotated display module 200 drives the adjacent display module 200 to rotate through the angle adjustment device 100 The display module 200 spaced apart from the currently rotating display module 200 is driven by two angle adjustment devices 100 located in the intermediate display module 200, so that the intermediate display module 200 rotates while driving the spaced display module 200 to rotate. In this way, all the display modules 200 of the same display screen 10 are linked to complete the angle adjustment of the display screen 10, so that the angle adjustment process of the display screen 10 is convenient and quick.

When a display module 200 is used, one of the display modules 200 drives the first base 110 to rotate so that the first base 110 is rotated relative to the first connection portion 132, and the first base 110 drives the first connection portion 132 relative to the second support link 150 turns, and because the second support link 150 is rotationally connected to the second base 140, the first connecting portion 132 drives the second support link 150 to rotate relative to the second base 140, so that the first base 110 and the second base 140 are rotated. A link linkage mechanism is formed between them for transmission, so that two adjacent display modules 200 can rotate relative to each other and can form any angle therebetween, so as to meet different display plane structure requirements of the display screen 10. For the display screen 10 composed of three or more display modules 200 in abutment, two adjacent display modules 200 can be connected through an angle adjustment device 100 to ensure that two adjacent display modules 200 are always in contact and In a coordinated manner, two angle adjustment devices 100 are arranged on any display module 200 in the middle of the display screen 10 for transmission, that is, the first base 110 and one of the angle adjustment devices 100 are simultaneously provided on any one display module 200 in the middle. The second base 140 of the other angle adjusting device 100 meshes and drives the first gear engaging portions 134 and the second gear engaging portions 164 of the two angle adjusting devices 100 located in the same display module 200.

When an included angle between two adjacent display modules 200 needs to be adjusted, one of the display modules 200 of the display screen 10 is rotated, and the rotated display module 200 drives the adjacent display module 200 to rotate through the angle adjustment device 100 The display module 200 spaced apart from the currently rotating display module 200 is driven by two angle adjustment devices 100 located in the intermediate display module 200, so that the intermediate display module 200 rotates while driving the spaced display module 200 to rotate. In this way, all the display modules 200 of the same display screen 10 are linked to complete the angle adjustment of the display screen 10, and the adjustment process of the display screen 10 is convenient and fast, and the operation flexibility and uniformity of the angle adjustment of the display screen 10 are good. Adjacent two display modules 200 of the above display screen 10 are always in contact with each other, so as to achieve accurate splicing of the display screen 10. In this embodiment, the angle adjusting device 100 has a six-link structure, so that it is driven according to the six-link principle.

The above-mentioned display screen adopts two or more angle adjustment devices, which can realize positive and negative large-angle adjustment. Adopt multiple gear meshing linkages. When adjusting one or more display modules, the radian variable is transmitted by the angle adjustment device. All display modules are simultaneously and evenly linked to achieve an even distribution of the adjustment angles. The modules are always kept on the same arc to achieve the stepless adjustment of the angle between the display modules and the purpose of the same angle between the display modules, and finally achieve the best display effect. The angle adjustment device can play a role of connecting a display module, and in practical applications, it is not limited to this connection method.
