Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present application, "a plurality" means two or more, unless otherwise specifically defined.

[0050] The following will describe in detail some embodiments of the present application with reference to the drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0051] As Figures 1 to 7 shown, the present application provides a display screen, including a display module 200, a cabinet frame 100, and a control box. The display module 200 is installed on the cabinet frame 100, and the control box is disposed on a side of the cabinet frame 100 facing away from the display module 200 and is electrically connected to the display module 200 for realizing the transmission of electrical signals, such as power supply or the transmission of other data.

[0052] In an optional embodiment, the control box includes a box body, a battery assembly, a communication module, and a control card. The box body is provided with a cavity, the communication module and the control card are disposed in the cavity of the box body, and the battery assembly is connected to the box body and enclosed in the cavity of the box body. Among them, an installation groove 1012 is formed on the cabinet frame 100, and the box body is installed in the installation groove 1012.

[0053] In an optional embodiment, the battery assembly, the communication module, and the control card are electrically connected, the control card is electrically connected to the display module 200, the battery assembly supplies power to the control card, the wireless communication module, and the display module 200, the communication module is used to receive externally input communication data and transmit it to the control card, and the control card is used to receive the communication data transmitted by the communication module and process it, and control the display operation of the display module 200 according to the processing result.

[0054] In an optional embodiment, as Figures 2 to 7As shown, the cabinet frame 100 includes a first frame 101, a second frame 102, a third frame 103 and an adjusting mechanism 104. The second frame 102 and the third frame 103 are rotatably mounted on both sides of the first frame 101 through the adjusting mechanism 104, so that the angles formed between the second frame 102 and the third frame 103 and the first frame 101 can be adjusted through the adjusting mechanism 104, enabling the cabinet frame 100 to cooperate with the shape of the display module 200 to form a corresponding curved screen or flat screen. The operation is simple and fast, and it can be applied to different application scenarios.

[0055] Exemplarily, for example, the shape of the display module 200 can be adjusted into different shapes according to the deformation amount. After the display module 200 is assembled to the cabinet frame 100, the cabinet frame 100 can adjust the angles formed between the second frame 102 and the third frame 103 and the first frame 101 according to the structure of the display module 200 through the adjusting mechanism 104, so that the display screen after the cabinet frame 100 and the display module 200 are assembled can form a corresponding arc-shaped display screen. It has the characteristics of reliable structure, high stability, and more convenient adjustment, and can be applied to different application scenarios.

[0056] After adopting the above technical solution, since the second frame 102 and the third frame 103 can freely adjust the angles formed between them and the first frame 101 through the adjusting mechanism 104, the display screen after the cabinet frame 100 and the display module 200 are assembled can form a corresponding curved screen or flat screen, and the shape of the curved screen can be adjusted according to the shape of the display module 200 through the adjusting mechanism 104. The operation is simple and fast. Since the cabinet frame 100 can be adjusted into a shape adapted to the display module 200 through the adjusting mechanism 104 after the cabinet frame 100 and the display module 200 are assembled, so that a single display screen unit presents a curved surface structure, and then multiple display screen units with curved surface structures are spliced to form a large display in a true curved surface form. Moreover, the adjustment angle of the adjusting mechanism 104 has flexibility and randomness, so that any special-shaped large-screen display such as an S-shaped or C-shaped can be formed, and it can be applied to different application scenarios.

[0057] In an alternative embodiment, as Figures 2 to 15As shown in the figure, the adjusting mechanism 104 includes an adjusting member 10, a transmission member 30, and a support member 20 having an arc-shaped groove 21. The adjusting member 10 is movably installed on the second frame 102 and the third frame 103 and passes through the arc-shaped groove 21. The support member 20 is fixedly connected to the first frame 101. Among them, a part of the structure of the transmission member 30 is fixedly connected to the adjusting member 10, and another part of the structure of the transmission member 30 is fixedly connected to the first frame 101, so that the adjusting mechanism 104 can adjust the angle formed between the second frame 102 and the third frame 103 and the first frame 101 through the transmission member 30, enabling the box frame 100 to cooperate with the shape of the display module 200 to form a corresponding curved screen or flat screen. The operation is simple and fast, and it can be applied to different application scenarios.

[0058] Exemplarily, the adjusting member 10 includes a rotating shaft 11, and the transmission member 30 includes a gear 31 and a rack 32 that mesh with each other. The rotating shaft 11 is rotatably installed on the second frame 102 and the third frame 103. The gear 31 is fixedly connected to the rotating shaft 11, and the rack 32 is fixedly connected to the first frame 101. When the rotating shaft 11 is rotated, the gear 31 rotates along the direction of the rack 32, enabling the second frame 102 and the third frame 103 to rotate around the axis of the rotating shaft 11, thereby realizing the adjustment of the angle formed between the second frame 102 and the third frame 103 and the first frame 101, enabling the box frame 100 to cooperate with the shape of the display module 200 to form a corresponding curved screen or flat screen. The operation is simple and fast, and it can be applied to different application scenarios. It solves the problem of the relatively single use of the display screen, meets the splicing requirements of conventional screens and special-shaped screens, and enables the display screen to be applied to different application scenarios.

[0059] In an alternative embodiment, the transmission member 30 includes a gear 31 and a rack 32. The gear 31 is connected to the adjusting member 10, and the rack 32 is connected to the first frame 101. The gear 31 is in transmission connection with the rack 32, so that the adjusting member 10 can drive the gear 31 to rotate along the direction of the rack 32, and then drive the second frame 102 and the third frame 103 to rotate relative to the first frame 101 around the axis of the gear 31 to realize the angle adjustment of the second frame 102 and the third frame 103.

[0060] In an alternative embodiment, first fixing ends 22 are respectively provided at both ends of the support member 20, a first connection hole is provided in the middle of the support member 20, a second connection hole is provided on the rack 32, and the position of the second connection hole corresponds to the position of the first connection hole, so that the rack 32 can be fixedly connected to the support member 20 through a locking member such as a pin or a screw. The support member 20 is fixed to the first frame 101 through the first fixing ends 22.

[0061] In an optional embodiment, the adjusting member 10 includes a rotating shaft 11 and a connecting block 12, and the rotating shaft 11 is rotatably connected to the second frame 102 and the third frame 103 through the connecting block 12. The connecting block 12 can play a supporting role when holding the rotating shaft 11 to adjust the arc, so as to prevent the box frame 100 from sliding down.

[0062] For example, when the angle of the box frame 100 needs to be adjusted, the operator holds the rotating shaft 11, and the connecting block 12 contacts the operator's hand to support the operator's hand, thereby preventing the box frame 100 from sliding down.

[0063] In an optional embodiment, there are two adjusting members 10, one of which is disposed between the second frame 102 and the first frame 101, and the other is disposed between the third frame 103 and the first frame 101, so that the second frame 102 and the third frame 103 can both adjust the angle between themselves and the first frame 101 through their respective connected adjusting members 10.

[0064] In an optional embodiment, the first frame 101 includes a first body and an arc-shaped arm 1011 arranged on both sides of the first body, the rack 32 of the transmission member 30 and the support member 20 are fixed on the arc-shaped arm 1011, and the gear 31 of the transmission member 30 is rotatably installed on the second frame 102 and the third frame 103 through the rotating shaft 11, so that when the rotating shaft 11 is rotated, the second frame 102 and the third frame 103 can rotate around the axis of the gear 31 to achieve angle adjustment of the second frame 102 and the third frame 103.

[0065] In an optional embodiment, a scale mark 10111 is provided on the arc arm 1011, and the scale mark 10111 is used to cooperate with the connecting block 12 of the adjusting member 10, so that the connecting block 12 can point to different scales on the scale mark 10111 when the adjusting member 10 adjusts the angle, so as to display the angle between the second frame 102 and the third frame 103 and the first frame 101.

[0066] In an optional embodiment, an indicator block 122 is provided on the connecting block 12, and the indicator block 122 is used to indicate the specific scale of the scale mark 10111 to display the angle between the second frame 102 and the third frame 103 and the first frame 101 in the current adjustment state.

[0067] In an optional embodiment, extension portions are provided at intervals on the second frame 102 and the third frame 103 , both ends of the adjusting member 10 are rotatably mounted on the extension portions, and one end of the rotating shaft 11 is transmission-connected to the rack 32 of the transmission member 30 through the gear 31 of the transmission member 30 .

At the same time, both rotating shafts 11 pass through the corresponding support members 20 and can move within the arc-shaped grooves 21. The gears 31 are located at both ends of the two rotating shafts 11 and are respectively engaged with the racks 32 provided at both ends of the two rotating shafts 11.

[0069] In an alternative embodiment, a first rotating groove 121 adapted to the rotating shaft 11 is formed on the connecting block 12, and second rotating grooves adapted to the rotating shaft 11 are formed on the first extension portion 1021 and the second extension portion. The first rotating groove 121 and the second rotating grooves cooperate to form a rotating hole capable of accommodating the rotation of the rotating shaft 11.

[0070] In an alternative embodiment, the adjusting member 10 includes a bearing member 13, and the bearing member 13 is installed at both ends of the two rotating shafts 11 to ensure the smooth rotation of the rotating shafts 11 relative to the second frame 102 and the third frame 103.

[0071] In an alternative embodiment, the rotating shaft 11 includes a shaft body member 111 and a jacket member 112.

[0072] In an alternative embodiment, as Figure 4 , Figure 12 , Figure 15 , Figures 16 to 18 shown, the adjusting mechanism 104 further includes a locking structure 40. The locking structure 40 is provided on the second frame 102 and the third frame 103 and is used to cooperate with at least part of the structure of the transmission member 30 to limit the movement of the adjusting member 10 within the arc-shaped groove 21, such that after the second frame 102 and the third frame 103 adjust the angle formed with the first frame 101 through the adjusting member 10, they are limited by the locking structure 40, avoiding the rotation of the second frame 102 and the third frame 103 relative to the first frame 101 when the angle is not adjusted, which may affect the splicing effect of the display screen and even cause damage to the display module 200.

[0073] In an optional embodiment, the locking structure 40 includes a locking shell 41, a locking rod 42 and a locking block 43. The locking shell 41 is arranged on the second frame 102 and the third frame 103.
