In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise explicitly specified.

[0054] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following examples and features in the examples can be combined with each other without conflict.

[0055] As shown in FIGS. 1-6, the present application provides a display screen, comprising a display module 20, a box frame 10, and a control box. The display module 20 is mounted on the box frame 10, and the control box is arranged on the side of the box frame 10 opposite to the display module 20 and is electrically connected with the display module 20, for realizing the transmission of power supply and signals, such as power supply or other data transmission.

[0056] In an optional embodiment, the control box comprises 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 arranged in the cavity of the box body, and the battery assembly is connected with the box body and enclosed in the cavity of the box body. The box frame 10 is formed with a mounting groove, and the box body is mounted in the mounting groove.

[0057] In an optional embodiment, the battery assembly, the communication module, and the control card are electrically connected, the control card is electrically connected with the display module 20, the battery assembly provides electric energy for the control card, the wireless communication module, and the display module 20, the communication module is used for receiving externally input communication data and transmitting the communication data to the control card, the control card is used for receiving the communication data transmitted by the communication module and processing the communication data, and the display work of the display module 20 is controlled according to the processing result.

[0058] In an optional embodiment, as shown in FIGS. 1-11, the box frame 10 comprises a first frame 11, a second frame 12, and an adjusting mechanism 13, the adjusting mechanism 13 comprises a holding structure 132 and an adjusting structure 131 for adjusting the curvature of the display screen, the adjusting structure 131 is connected between the first frame 11 and the second frame 12, and the holding structure 132 is used for holding when the first frame 11 is rotated to a preset angle relative to the second frame 12, effectively preventing the box frame 10 from loosening and rebounding due to external force or its own gravity, ensuring the stability and consistency of the display screen. Not only can various curvature adjustments of the display screen be achieved through the adjusting structure 131 to adapt to different installation scenarios and visual needs, improving the versatility of the product, but also solving the inherent stability problem of the adjustable screen, avoiding the change of curvature due to shaking during use, thereby ensuring high-quality image display. Even the present application can also reduce the wear and tear of components or the fatigue of connection points caused by the shaking of the box frame 10 through the holding structure 132, thereby prolonging the service life of the box frame 10.

[0059] It should be noted that the preset angle refers to any unfolded angle of the first frame 11 relative to the second frame 12 between the minimum rotation angle position and the maximum rotation angle position, which is not limited by the present application.

[0060] In an optional embodiment, the number of first frames 11 is two, and the two first frames 11 are connected on both sides of the second frame 12 through the adjusting mechanism 13. The control box is arranged on the side of the second frame 12 facing away from the display module 20. The display module 20 is a flexible structure that can be bent, so as to adapt to the angle adjustment of the first frame 11 and the second frame 12, thereby cooperating with the box frame 10 to form a corresponding curved screen or a straight screen, which is simple and quick to operate and can be applied to different application scenarios.

[0061] In an optional embodiment, as shown in FIGS. 10-17, the adjusting structure 131 comprises an adjusting rod 1312 and a mounting seat 1311, the mounting seat 1311 is mounted on the first frame 11 of the display screen, one end of the adjusting rod 1312 is movably connected with the mounting seat 1311, and the other end of the adjusting rod 1312 is rotatably connected with the second frame 12 of the display screen after extending out of the mounting seat 1311, so that the first frame 11 can adjust the angle relative to the second frame 12 by the length of the adjusting rod 1312 extending out, and the angle adjustment between the first frame 11 and the second frame 12 is realized. The display module 20 mounted on the box frame 10 can cooperate with the box frame 10 to form a corresponding curved screen or a straight screen, that is, the display module 20 can be deformed adaptively under the control of the box frame 10 after being mounted on the box frame 10, thereby cooperating with the box frame 10 to form a corresponding curved screen or a straight screen, which is simple and quick to operate and can be applied to different application scenarios.

[0062] For example, when the display module 20 is assembled to the cabinet frame 10, the cabinet frame 10 can adjust the angle between the second frame 12 and the first frame 11 according to the structure of the display module 20 through the adjusting structure 131, so that the display module 20 mounted on the cabinet frame 10 can cooperate with the cabinet frame 10 to form a corresponding curved screen or a straight screen, that is, the display module 20 can be deformed under the control of the cabinet frame 10 after being mounted on the cabinet frame 10, so as to cooperate with the cabinet frame 10 to form a corresponding curved screen or a straight screen. When the display screen is adjusted to a preset angle, the retaining structure 132 locks this state to prevent accidental shape change due to gravity, vibration or other external forces during use, thereby achieving firm retention of the preset angle and avoiding shaking and deformation.

[0063] After the above technical scheme is adopted, the first frame 11 can freely adjust the angle between the first frame 11 and the second frame 12 through the adjusting structure 131, so that the display screen after the cabinet frame 10 and the display module 20 are assembled can form a corresponding curved screen or a straight screen, and the shape of the curved screen can be adjusted according to the shape of the display module 20 through the adjusting structure 131, which is simple and convenient to operate. At the same time, the first frame 11 cannot move or rotate relative to the second frame 12 through the retaining structure 132, so that firm retention of the first frame 11 at a preset angle relative to the second frame 12 can be achieved, external force impact and vibration can be effectively resisted, and shaking and deformation can be avoided. Since the cabinet frame 10 and the display module 20 can be adjusted to a shape suitable for the display module 20 through the adjusting structure 131 after being assembled, the single display screen unit presents a curved surface structure, and multiple curved surface display screen units are spliced to form a large display with a true curved surface. At the same time, the adjusting angle of the adjusting structure 131 has flexibility and randomness, so that an S-shaped or C-shaped large screen display with any special shape can be formed, and then the retaining structure 132 is combined to firmly lock the adjusted display screen, so as to avoid changes in the curvature due to shaking during use, thereby ensuring high-quality image display and being applicable to different application scenarios.

[0064] In an optional embodiment, the first frame 11 is provided with a first mounting portion 111, the second frame 12 is provided with a second mounting portion 121, the mounting seat 1311 and at least part of the retaining structure 132 are mounted on the first mounting portion 111, and the adjusting rod 1312 and at least part of the retaining structure 132 are connected with the second mounting portion 121. The first mounting portion 111 can be a rib structure on the first frame 11, which is connected on the opposite sides of the first frame 11, so as to not only strengthen the strength of the first frame 11, but also fix the first mounting portion 111, so that the first frame 11 can be connected with the second frame 12. Similarly, the second mounting portion 121 can be a boss structure on the second frame 12, which can be fixed on the first frame 11 by welding or one-piece forming.

[0065] In the embodiment, the adjusting rod 1312 is rotationally connected with the shaft hole of the second mounting portion 121 through a connecting pin, at least part of the retaining structure 132 is mounted on the side of the second mounting portion 121 close to the display module 20, another part of the retaining structure 132 is fixed on the mounting seat 1311, the mounting seat 1311 is mounted on the first mounting portion 111, at least part of the retaining structure 132 is movably connected with another part of the retaining structure 132, and the end of the adjusting rod 1312 away from the second mounting portion 121 is telescopically mounted in the mounting seat 1311. In this way, when the length of the adjusting rod 1312 is elongated or shortened, the first frame 11 can be pushed to rotate around the shaft hole of the second mounting portion 121, so as to form a controllable included angle, and then the angle adjustment between the first frame 11 and the second frame 12 is realized. The structure of the traditional box frame 10 is broken through, so that the dynamic deformation of the box frame 10 can be realized through the mechanical adjusting structure 131, and a self-locking mechanical structure is added for the arc adjustment of the display screen by the two-part retaining structure 132, so as to solve the problem that the arc screen is easy to shake and deform after adjustment in the prior art, and the display effect is affected. The present application has significant application value in the fields of large LED display screens and deformable billboards.

[0066] In an optional embodiment, the retaining mechanism comprises a limiting rod 1322 and a limiting seat 1321, the limiting seat 1321 is arranged on the second frame 12, one end of the limiting rod 1322 is connected with the adjusting structure 131 arranged on the first frame 11, and the other end of the limiting rod 1322 is movably arranged in the limiting seat 1321, for limiting the first frame 11 at the zero-degree position and the maximum rotation angle position relative to the second frame 12, so that when the first frame 11 and the second frame 12 are rotated to the fully flat or maximum angle position, the limiting rod 1322 can prevent the first frame 11 from continuing to rotate forward relative to the second frame 12, not only can the friction or locking force be provided at the zero-degree position and the maximum rotation angle position, but also the planarity or camber of the display screen when rotated to the two angles can be better guaranteed, and the structure of the display screen can be prevented from being damaged due to the excessively large angle, so that the flexibility of use is guaranteed, the safety and reliability of operation are ensured, and the display screen is very suitable for application scenarios that need to repeatedly change the camber and the installation environment is complex.

[0067] In an optional embodiment, the limiting rod 1322 is provided with a matching part 13221, and the limiting seat 1321 is provided with an abutting part 13211, the abutting part 13211 can cooperate with the matching part 13221 when the limiting rod 1322 is at the zero-degree position, so as to ensure the planarity of the display screen at the zero-degree position, to meet the professional display requirements, to provide a unique and accurate mechanical position for the display screen at the zero-degree position, and to ensure that the display screen is restored to the absolute same position at the zero-degree position each time; meanwhile, the rigidity of the connecting point of the display screen at the zero-degree position is greatly enhanced through the cooperation of the abutting part 13211 and the matching part 13221, the torsion or external force of the display screen is resisted, deformation is avoided, and the gap that may exist in the simple limiting mode is eliminated, so that the first frame 11 and the second frame 12 work like a solid overall box frame 10.

[0068] It should be noted that the traditional limiting mode may have a small wobble or gap, and for the display screen, this little gap is reflected at the connecting position of the two box frames 10, which may damage the absolute flatness of the screen as a whole, especially when displaying a pure color picture, a shadow or bright line may be seen at the joint, which seriously affects the visual experience. Therefore, through the cooperation of the abutting part 13211 and the matching part 13221, not only a unique and accurate mechanical position is provided when the first frame 11 is rotated to the zero-degree position relative to the second frame 12, so as to ensure that the display screen is restored to the absolute same position at the zero-degree position each time, but also the rigidity of the connecting point at the zero-degree position is greatly enhanced, the torsion or external force of the screen is resisted, and deformation is avoided.

[0069] For example, when the operator rotates the first frame 11 relative to the second frame 12 to a position close to full flattening, the abutting portion 13211 will be precisely embedded or fitted into the matching portion 13221, so as to effectively eliminate the manufacturing tolerances and assembly gaps between all moving parts. Among them, the abutting portion 13211 can be a specific structure processed on the limiting rod 1322, such as a groove, a plane, a protrusion or a precisely processed shaft segment. The abutting portion 13211 can be a specific complementary structure processed on the limiting seat 1321, which can also be a protrusion, a plane or a clamping groove, to achieve precise positioning of the first frame 11 relative to the second frame 12 at the zero-degree position through face contact or interference fit, rather than simple point contact or line contact.

[0070] In an optional embodiment, the limiting seat 1321 is provided with a movable slot 13212, the abutting portion 13211 is arranged on the side walls on the opposite sides of the movable slot 13212, and the limiting rod 1322 is provided with a matching portion 13221 on the opposite sides, so as to realize over-positioning through the simultaneous contact or mutual constraint of the two sides, eliminate the possible small gap of the freedom degree of the display screen in the length, width and / or height direction of the limiting rod 1322, and be much more stable and accurate than simply arranging a matching portion 13221 on one side, and also ensure that there is no looseness between the first frame 11 and the second frame 12 at the zero-degree position, like a whole solid, thereby providing the most basic mechanical guarantee for the excellent flatness of the display screen.

Among them, arranging the abutting portion 13211 at the tooth top of the tooth structure 13213 can ensure the precise position of the abutting portion 13211 in the movable slot 13212, and also can reduce the friction force when the limiting rod 1322 slides relative to the limiting seat 1321, so that the user can smoothly switch between different curvatures.

In addition, the friction block 1315 of the present application can also be subjected to elastic force by a spring structure, which is used to push the friction block 1315 to one side of the rack structure 131221, so that the friction block 1315 can increase the pressing force applied to the rack structure 13122 by the spring structure as the wear increases.

[0090] In an optional embodiment, the friction block 1315 is provided with a protruding part in a triangular cross section, and the angle of the protruding part is greater than the angle of the meshing teeth of the rack structure 13122, so that the sliding of the connecting rod 13121 is more smooth and has a movement feedback.

[0106] In an alternative embodiment, the box frame 10 further comprises a protection structure 15, the protection structure 15 comprises a protective sheet 152, a reset piece 153, and a fixing seat 151 mounted on the first frame 11, the fixing seat 151 is provided with a guide groove 1512 obliquely, the protective sheet 152 is provided with a connecting shaft 154, the connecting shaft 154 is slidingly mounted in the guide groove 1512, and the two ends of the reset piece 153 are respectively abutted with the fixing seat 151 and the protective sheet 152, so as to always have an elastic force in the direction away from the fixing seat 151 to drive the protective sheet 152 to move away from the fixing seat 151, thereby protecting the display module 20 mounted on the box frame 10 from being damaged during disassembly or transportation.

[0107] For example, the first frame 11 is provided with a fixing groove and a avoiding groove, and the fixing seat 151 is fixed in the fixing column in the fixing groove. The protective sheet 152 is provided with a connecting boss 1522 and a guide boss 1521, the outer side wall of the second frame 12 is provided with an avoiding groove, the connecting shaft 154 is connected with the guide groove 1512 after passing through the connecting boss 1522, and the guide boss 1521 is used to cooperate with the avoiding groove, so that the protective sheet 152 can move to the side away from the display module 20 when being pressed, so that the two frame structures can be well spliced together.

[0108] In an optional embodiment, the fixing seat 151 is provided with a guide inclined surface 1513 and an inclined surface groove 1511, one end of the reset member 153 is installed in the inclined surface groove 1511, and the other end of the reset member 153 abuts against the connecting shaft 154, so that the connecting shaft 154 can drive the protective sheet 152 to move away from the fixing seat 151. Wherein, the inclination angle of the guide inclined surface 1513 is the same as the inclination angle of the inclined surface groove 1511 and the guide groove 1512, so that the fixing seat 151 can be inclinedly installed in the fixing groove along the guide inclined surface 1513, so as to ensure the parallelism of the protective sheet 152 and the outer side wall of the first frame 11, and also make the protective sheet 152 move along the guide direction of the guide groove 1512 through the guide boss 1521 and retract into the avoiding groove.

[0109] For example, the first frame body has opposite first and second corners, and the protection structure 15 is installed thereon. When the two cabinet frame bodies are spliced, the protective sheet 152 moves towards the opposite direction of the two cabinet frame bodies and applies external force to each other, so that the protective sheet 152 can retract into the first frame body, and the two cabinet frame bodies can be spliced together well.

[0110] In an optional embodiment, the cabinet frame 10 further comprises a first positioning column arranged on one side of the protection structure 15 for limiting the movement of the protective sheet 152.

[0111] For example, the cabinet frame 10 is provided with a movable hole communicating with the fixing groove, and the first positioning column has an abutting end and a limiting end. The limiting end is used for cooperating with the protective sheet 152 to limit the movement of the protective sheet 152 away from the display module 20, so as to prevent the protective sheet 152 from retracting.

[0113] In an optional embodiment, the module bottom shell 21 has a first end face and a second end face. The first end face is arranged opposite to the second end face. The lamp plate 22 is installed on the first end face. The second end face is used for connecting with the cabinet frame 10, so that the cabinet frame 10 can control the display module 20 to deform adaptively and form a corresponding curved screen or a straight screen together.

[0114] In an optional embodiment, the module bottom shell 21 comprises a plurality of shells arranged in sequence along the first direction, and at least a limiting assembly 23 is connected between two adjacent shells, the limiting assembly 23 being used to limit the deformation amount of the module bottom shell 21 when the module bottom shell 21 is bent and deformed, so as to avoid the display module 20 from being damaged due to the excessive deformation amount of the module bottom shell 21, and ensure that the display module 20 can be normally used.

[0115] For example, the shells comprise a first shell 21a and a second shell 21b, one part of the limiting assembly 23 is formed on the first shell 21a, and the other part of the limiting assembly 23 is formed on the second shell 21b. When the display surface of the display module 20 is concave and the deformation amount reaches the maximum, that is, the display module 20 is bent into a U-shaped structure, at this time, the limiting assembly 23 can form a limit for limiting the relative displacement amount between the first shell 21a and the second shell 21b, so that the module bottom shell 21 no longer deforms more, avoiding the display module 20 from being damaged due to the excessive deformation amount of the module bottom shell 21, and ensuring that the display module 20 can be normally used.

[0116] Alternatively, when the display surface of the display module 20 is convex and the deformation amount reaches the maximum, that is, the display module 20 is bent into an n-shaped structure, at this time, the limiting assembly 23 can form a limit for limiting the relative displacement amount between the first shell 21a and the second shell 21b, so that the module bottom shell 21 no longer deforms more, avoiding the display module 20 from being damaged due to the excessive deformation amount of the module bottom shell 21, and ensuring that the display module 20 can be normally used.

[0117] After the above technical scheme is adopted, since the module bottom shell 21 is relatively flexible, it is easy to be damaged due to the excessive deformation amount during the transportation or assembly process. Therefore, the limiting assembly 23 is used to limit the deformation amount of the module bottom shell 21 when it is bent and deformed, so as to avoid the risk that the display module 20 is damaged due to the excessive bending and deformation of the module bottom shell 21 during the transportation or assembly process, and ensure that the display module 20 can be normally used.

[0118] In an optional embodiment, the limiting assembly 23 comprises a first limiting part 231 and a second limiting part 232, the first limiting part 231 being formed on one of the two adjacent shells, the second limiting part 232 being formed on the other of the two adjacent shells, and the first limiting part 231 and the second limiting part 232 being matched to limit the relative displacement amount between the two adjacent shells, so as to avoid the display module 20 from being damaged due to the excessive deformation amount of the module bottom shell 21, and ensure that the display module 20 can be normally used.

[0119] In an optional embodiment, the first limiting portion 231 has a first abutting portion 13211, and the second limiting portion 232 has a second abutting portion 13211. When the bottom shell 21 of the display module 20 is bent, the first abutting portion 13211 abuts against the second abutting portion 13211 or the end opposite to the second abutting portion 13211, so that the bottom shell 21 of the display module 20 is no longer bent, thereby avoiding damage to the display module 20 due to excessive bending, and ensuring that the display module 20 can be normally used.

[0120] For example, when the display surface of the display module 20 is concave and the bending amount reaches the maximum, the first abutting portion 13211 abuts against the second abutting portion 13211 to form a limit, so as to limit the relative displacement amount between the first shell 21a and the second shell 21b, so that the bottom shell 21 of the display module 20 is no longer bent, thereby avoiding damage to the display module 20 due to excessive bending, and ensuring that the display module 20 can be normally used.

[0121] Alternatively, when the display surface of the display module 20 is convex and the bending amount reaches the maximum, the end opposite to the first abutting portion 13211 abuts against the second abutting portion 13211, that is, the first abutting portion 13211 abuts against the side wall of the second shell 21b, and the end opposite to the second abutting portion 13211 abuts against the first abutting portion 13211, that is, the second abutting portion 13211 abuts against the side wall of the first shell 21a, so as to limit the relative displacement amount between the first shell 21a and the second shell 21b, so that the bottom shell 21 of the display module 20 is no longer bent, thereby avoiding damage to the display module 20 due to excessive bending, and ensuring that the display module 20 can be normally used.
