[0052] Next, some embodiments of the present application will be described in detail in conjunction with the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0053] As Figures 1 to 2 shown, the present application provides a display screen, including a display module 200, a box frame 100, and a control box 300. The display module 200 is installed on the box frame 100, and the control box 300 is disposed on the side of the box 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.

[0054] In an optional embodiment, the control box 300 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 is formed on the box frame 100, and the box body is installed in the installation groove.

[0055] In an alternative 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 electrical energy 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. The control card is used to receive the communication data transmitted by the communication module, process it, and control the display operation of the display module 200 according to the processing result.

[0056] In an alternative embodiment, as Figures 1 to 15 shown, the cabinet frame 100 includes a first frame 101, a second frame 102, a third frame 103, a connection structure 105, and an adjustment mechanism 104 having an adjustment rod 10. Both ends of the first frame 101 are respectively rotatably connected to the second frame 102 and the third frame 103 through the connection structure 105. The adjustment mechanism 104 is disposed on the second frame 102 and the third frame 103 and is rotatably connected to the first frame 101 through the adjustment rod 10, so that the second frame 102 and the third frame 103 can control the angle formed between the second frame 102 and the third frame 103 and the first frame 101 by the length of the adjustment rod 10 extending, such that the display module 200 mounted on the cabinet frame 100 can cooperate with the cabinet frame 100 to form a corresponding curved screen or flat screen, that is, the display module 200 can be adaptively deformed under the control of the cabinet frame 100 after being mounted on the cabinet frame 100, so as to be able to cooperate with the cabinet frame 100 to form a corresponding curved screen or flat screen. The operation is simple, fast, and can be applied to different application scenarios.

[0057] Exemplarily, for example, the shape of the display module 200 is an arc structure that can be adjusted to different radian according to its deformation amount. After the display module 200 is assembled to the cabinet frame 100, the cabinet frame 100 can adjust the angle 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 adjustment mechanism 104, such that the display module 200 mounted on the cabinet frame 100 can cooperate with the cabinet frame 100 to form a corresponding curved screen or flat screen, that is, the display module 200 can be adaptively deformed under the control of the cabinet frame 100 after being mounted on the cabinet frame 100, so as to be able to cooperate with the cabinet frame 100 to form a corresponding curved screen or flat screen. It has the characteristics of reliable structure, high stability, more convenient adjustment, etc., and can be applied to different application scenarios.

[0058] Exemplarily, the first frame 101 has opposite first and second ends. One side of the first end is rotatably connected to the second frame 102 through the first connection structure 105, and the other side of the first end is rotatably connected to the third frame 103 through the second connection structure 105. Similarly, one side of the second end is rotatably connected to the other end of the second frame 102 through the third connection structure 105, and the other side of the second end is rotatably connected to the other end of the third frame 103 through the fourth connection structure 105. That is, the first frame 101 is rotatably connected to the second frame 102 and the third frame 103 through four connection structures 105, so that the second frame 102 and the third frame 103 can be rotatably installed on both sides of the first frame 101. Among them, the adjusting mechanism 104 is installed in the middle of the second frame 102 and the third frame 103, and the adjusting rods 10 of the adjusting mechanism 104 are respectively rotatably connected to both sides of the first frame 101. That is, one side of the first frame 101 is connected to the second frame 102 through one of the adjusting mechanisms 104, and the other side of the first frame 101 is connected to the third frame 103 through the other adjusting mechanism 104, so that the two adjusting mechanisms 104 can correspondingly adjust the angle formed by the second frame 102 relative to the first frame 101 and the angle formed by the third frame 103 relative to the first frame 101, so that the display module 200 installed on the box frame 100 can cooperate with the box frame 100 to form a corresponding curved screen or flat screen. That is, after the display module 200 is installed on the box frame 100, it can be adaptively deformed under the control of the box frame 100 so as to be able to cooperate with the box frame 100 to form a corresponding curved screen or flat screen. The operation is simple and fast, and it can be applied to different application scenarios.

[0059] After adopting the above technical solution, since the second frame 102 and the third frame 103 can freely adjust the angle formed between them and the first frame 101 through the adjusting mechanism 104, the display screen after the box 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 by the adjusting mechanism 104 according to the shape of the display module 200. The operation is simple and fast. Since the box frame 100 and the display module 200 can be adjusted into a shape adapted to the display module 200 through the adjusting mechanism 104 after being assembled, so that a single display screen unit presents a curved surface structure, and then a plurality of 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 displays such as S-shaped or C-shaped can be formed, and it can be applied to different application scenarios.

[0060] In an optional embodiment, the adjustment mechanism 104 includes a box handle 20 and a pressing piece 30, the box handle 20 is installed on the second frame 102 and the third frame 103, the other end of the adjustment rod 10 is slidably connected to the box handle 20, and the pressing piece 30 is used to lock or unlock the relative position of the adjustment rod 10 and the box handle 20, and is used to control the length of the adjustment rod 10 extending out of the box handle 20, so as to be able to control the angle of the second frame 102 relative to the first frame 101 and the angle of the third frame 103 relative to the first frame 101.

[0061] For example, when the box frame 100 needs to adjust the angle of the second frame 102 relative to the first frame 101, the pressing member 30 is operated to unlock the adjusting rod 10 and the box handle 20, and then the length of the adjusting rod 10 extending out of the box handle 20 is controlled so that the second frame 102 can rotate relative to the first frame 101 through the connecting structure 105. When the second frame 102 rotates to the desired angle, the pressing member 30 is released to lock the adjusting rod 10 and the box handle 20 to prevent the second frame 102 from rotating freely relative to the first frame 101. Similarly, the angle between the third frame 103 and the first frame 101 is also adjusted in the same way, which is simple and quick to operate and can be applied to different application scenarios.

[0062] In an optional embodiment, the box handle 20 includes a gripping portion 21, a connecting seat 22 and a mounting seat 23. The gripping portion 21 is connected to the second frame 102 and the third frame 103 via the connecting seat 22, and the adjusting rod 10 is rotatably connected to the connecting seat 22 via the mounting seat 23, so that when the adjusting rod 10 adjusts the length extending out of the box handle 20, the adjusting rod 10 can rotate relative to the connecting seat 22 via the mounting seat 23.

[0063] Exemplarily, the connecting seat 22 includes a first connecting seat 22a and a second connecting seat 22b, the first connecting seat 22a and the second connecting seat 22b are respectively connected to the second frame 102 at both ends of the holding portion 21, and the first connecting seat 22a and the second connecting seat 22b are respectively connected to the third frame 103 at both ends of the holding portion 21, and the adjusting rod 10 is connected to the first connecting seat 22a or the second connecting seat 22b through the mounting seat 23.

[0064] In an optional embodiment, the connecting seat 22 includes a first connecting block 221 and a second connecting block 222, and both ends of the mounting seat 23 are rotatably connected to the first connecting block 221 and the second connecting block 222 respectively, and the first connecting block 221 and the second connecting block 222 are connected to the second frame 102 and the third frame 103.

[0065] Exemplarily, the first connection seat 22a includes a first connection block 221 and a second connection block 222. The two ends of the mounting seat 23 are provided with mounting seat 23 rotating shafts, and the first connection block 221 and the second connection block 222 are provided with mounting seat 23 shaft holes. The mounting seat 23 rotating shafts are rotatably installed in the mounting seat 23 shaft holes, so that the mounting seat 23 can be rotatably installed between the first connection block 221 and the second connection block 222.

[0066] It should be noted that the structure of the second connection block 222 can be the same as that of the first connection seat 22a and is a split structure; the structure of the second connection block 222 can also be different from that of the first connection seat 22a and is an integral structure.

[0067] In an alternative embodiment, the cabinet handle 20 includes a gasket 70. The gasket 70 is installed on the mounting seat 23 rotating shaft and is located between the mounting seat 23 and the first connection block 221 and the second connection block 222.

[0068] In an alternative embodiment, the mounting seat 23 includes a first mounting seat 231 and a second mounting seat 232. The first mounting seat 231 and the second mounting seat 232 are buckled with each other to form a movable slot 23a. The adjusting rod 10 is slidably installed in the movable slot 23a, so that the length of the adjusting rod 10 extending out of the movable slot 23a can be adjusted to realize the angle adjustment of the second frame 102 and the third frame 103, so that the display screen can form a corresponding curved screen or a straight screen. The operation is simple and fast, solving the problem of relatively single use of the display screen, meeting the splicing requirements of conventional screens and special-shaped screens, and enabling the display screen to be applied to different application scenarios.

[0069] Exemplarily, the adjusting rod 10 has a first connection end 10a and a second connection end 10b. The first connection end 10a is rotatably connected to the first frame 101, and the second connection end 10b is slidably installed in the movable slot 23a.

[0070] In an alternative embodiment, the mounting seat 23 further includes a plurality of limiting posts 233. The two ends of the plurality of limiting posts 233 are respectively connected to the first mounting seat 231 and the second mounting seat 232 and are located on both sides of the adjusting rod 10, so that the end faces of the two ends of the adjusting rod 10 can be attached to the cylindrical surfaces of the limiting posts 233, further controlling the accuracy of the adjusting rod 10 when moving in the movable slot 23a and improving the accuracy of the angle adjustment of the cabinet frame 100.

[0071] Exemplarily, the number of the limiting posts 233 is four. Two of the limiting posts 233 are arranged at intervals on one side of the adjusting rod 10, and the other two limiting posts 233 are arranged at intervals on the other side of the adjusting rod 10, and the cylindrical surfaces of the four limiting posts 233 are all attached to the end faces of the adjusting rod 10.

[0072] In an alternative embodiment, the first mounting seat 231 and the second mounting seat 232 are provided with a limit post groove 23d, and the limit post 233 is movably inserted into the limit post groove 23d.

[0074] Exemplarily, the adjusting rod 10 is provided with a tooth groove 12 in the length direction, and the rack structure 40 is fixed in the tooth groove 12, so that the adjusting rod 10 can cooperate with the adjusting tooth 321 on the pressing member 30 through the rack structure 40 to achieve the locking or unlocking function, thereby the length of the adjusting rod 10 extending out of the box handle 20 can be controlled by the pressing member 30, and further the angle formed by the second frame 102 relative to the first frame 101 and the angle formed by the third frame 103 relative to the first frame 101 can be controlled.

[0075] In an alternative embodiment, the pressing member 30 includes a button 31 and a limit block 32 having the adjusting tooth 321. The mounting seat 23 of the box handle 20 is provided with a limit groove 23b, and the limit block 32 is movably mounted in the limit groove 23b. The button 31 is connected to the limit block 32 to drive the adjusting tooth 321 to engage or disengage with the rack structure 40. Wherein, the shapes of the limit groove 23b and the limit block 32 are both square structures to limit the rotation of the limit block 32 relative to the mounting seat 23 during the pressing process by the button 31, playing a limiting role.

One end of the shrapnel structure 60 is mounted on the mounting seat 23, and the other end of the shrapnel structure 60 is clamped with the rack structure 40 to limit the free movement of the rack structure 40, and at the same time, the feel of the adjusting rod 10 during length adjustment can also be increased.

[0077] In an alternative embodiment, the adjusting mechanism 104 includes a feedback member 50. The front surface of the adjusting rod 10 is provided with a scale 11, and the back surface of the adjusting rod 10 is provided with a feedback hole 13 corresponding to the scale 11. The feedback member 50 cooperates with the feedback hole 13 to form a signal indicator, capable of providing an in-place reminder function.

[0078] Exemplarily, the distance between two adjacent feedback holes 13 corresponds to five scale values on the scale 11, so that when the adjusting rod 10 adjusts the length, the feedback member 50 can cooperate with each feedback hole 13 on the adjusting rod 10 to provide an in-place reminder function, preventing the adjusting rod 10 from being too long or too short during length adjustment, and thus the length of the adjusting rod 10 extending out of the movable slot 23a can be better controlled.

When the first box body and the second box body are spliced, the two protective pieces 1061 move in opposite directions and exert external forces on each other, so that the protective pieces 1061 can retract into the first box body and the second box body, enabling the first box body and the second box body to be spliced together well.

[0093] In an alternative embodiment, the box body frame 100 further includes a first positioning post 107 and a second positioning post 108.

[0094] It should be noted that the first positioning post 107 and the second positioning post 108 on the first box body are arranged in a staggered manner with the first positioning post 107 and the second positioning post 108 on the second box body, so that the first positioning post 107 on the first box body can drive the second positioning post 108 on the second box body to release the limiting effect on the protective piece 1061, and the first positioning post 107 on the second box body can drive the second positioning post 108 on the first box body to release the limiting effect on the protective piece 1061.

[0095] Exemplarily, the box body frame 100 is provided with an activity hole communicated with the fixed groove. The second positioning post 108 has an abutting end and a limiting end.

The lamp board 2022 is disposed on the module bottom case 201 so that the display module 200 can form an arc-shaped display screen that cooperates with the box frame 100.

[0097] In an alternative embodiment, the module bottom case 201 has a first end face and a second end face which are oppositely arranged. The lamp board 2022 is mounted on the first end face, and the second end face is used to connect with the box frame 100 so that the box frame 100 can control the display module 200 to undergo adaptive deformation and jointly form a corresponding curved screen or flat screen.

[0098] In an alternative embodiment, the module bottom case 201 includes a plurality of cases arranged in sequence along a first direction, and at least a limiting component is connected between adjacent two cases. The limiting component is used to limit the amount of deformation when the module bottom case 201 undergoes bending deformation, so as to prevent the display module 200 from being damaged due to excessive deformation amount of the module bottom case 201 and ensure that the display module 200 can be used normally.

[0099] Exemplarily, the case includes a first case 201a and a second case 201b. A part of the structure of the limiting component is formed on the first case 201a, and another part of the structure of the limiting component is formed on the second case 201b. When the display surface of the display module 200 is concave and the deformation amount reaches the maximum, that is, when the display module 200 is bent into a U-shaped structure, at this time, the limiting component can form a limit to limit the relative displacement amount between the first case 201a and the second case 201b, so that the module bottom case 201 no longer undergoes more deformation, preventing the display module 200 from being damaged due to excessive deformation amount of the module bottom case 201 and ensuring that the display module 200 can be used normally.

[0100] Or, when the display surface of the display module 200 is convex and the deformation amount reaches the maximum, that is, when the display module 200 is bent into an N-shaped structure, at this time, the limiting component can form a limit to limit the relative displacement amount between the first case 201a and the second case 201b, so that the module bottom case 201 no longer undergoes more deformation, preventing the display module 200 from being damaged due to excessive deformation amount of the module bottom case 201 and ensuring that the display module 200 can be used normally.

[0101] After adopting the above technical solution, since the flexible module bottom case 201 is prone to damage the display module 200 due to excessive deformation during transportation or assembly. Therefore, in this application, the limiting component is used to limit the deformation amount of the module bottom case 201 during bending deformation, so as to avoid the risk of damage to the display module 200 caused by excessive bending deformation of the module bottom case 201 during transportation or assembly, and ensure that the display module 200 can be used normally.

[0103] In an alternative embodiment, the first limiting portion 2011 has a first abutting portion, and the second limiting portion 2012 has a second abutting portion. The first abutting portion abuts against the second abutting portion or the end opposite to the second abutting portion when the module bottom case 201 undergoes bending deformation, so that the module bottom case 201 no longer undergoes more deformation, thereby avoiding damage to the display module 200 caused by excessive deformation of the module bottom case 201 and ensuring that the display module 200 can be used normally.

[0104] Exemplarily, when the display surface of the display module 200 is concave and the deformation amount reaches the maximum, the first abutting portion abuts against the second abutting portion to form a limit, which is used to limit the relative displacement amount between the first case 201a and the second case 201b, so that the module bottom case 201 no longer undergoes more deformation, avoiding damage to the display module 200 caused by excessive deformation of the module bottom case 201 and ensuring that the display module 200 can be used normally.

[0105] Or, when the display surface of the display module 200 is convex and the deformation amount reaches the maximum, the first abutting portion abuts against the end opposite to the second abutting portion, that is, the first abutting portion abuts against the side wall of the second case 201b; the second abutting portion abuts against the end opposite to the first abutting portion, that is, the second abutting portion abuts against the side wall of the first case 201a, which is used to limit the relative displacement amount between the first case 201a and the second case 201b, so that the module bottom case 201 no longer undergoes more deformation, avoiding damage to the display module 200 caused by excessive deformation of the module bottom case 201 and ensuring that the display module 200 can be used normally.

[0106] In an alternative embodiment, the first limiting portion 2011 has a first connecting portion, and the second limiting portion 2012 has a second connecting portion.

The first abutting portion moves in the second limiting groove, and the second abutting portion moves in the first limiting groove. When the deformation amount of the display module 200 reaches the maximum, the first abutting portion can form a limit with two opposite end faces of the first limiting groove, and the second abutting portion can form a limit with two opposite end faces of the second limiting groove, so that the module bottom case 201 no longer deforms more, avoiding damage to the display module 200 caused by excessive deformation amount of the module bottom case 201, and ensuring that the display module 200 can be used normally.

[0107] In an alternative embodiment, the first abutting portion is perpendicularly connected to the first connecting portion, that is, the first abutting portion and the first connecting portion form an L-shaped structure.

[0108] In an alternative embodiment, the second abutting portion is perpendicularly connected to the second connecting portion, that is, the second abutting portion and the second connecting portion form an L-shaped structure.
