In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of this application, "a plurality" means two or more, unless otherwise specifically defined.

[0058] The following will describe in detail some embodiments of this application with reference to the drawings. Without conflict, the embodiments described below and the features in the embodiments can be combined with each other.

[0059] As Figures 1 to 3 shown, this application provides a display screen, including a display module 20, a box frame 10, and a control box 30. The display module 20 is installed on the box frame 10, and the control box 30 is disposed on a side of the box frame 10 facing away from the display module 20 and is electrically connected to the display module 20 for realizing the transmission of power and signals, such as power supply or the transmission of other data.

[0060] In an alternative embodiment, the control box 30 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 10, and the box body is installed in the installation groove.

[0061] 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 20, the battery assembly supplies power to the control card, the wireless communication module, and the display module 20, 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 20 according to the processing result.

[0062] In an alternative embodiment, as Figures 2 to 5As shown in the figure, the cabinet frame 10 includes a first frame 11, a second frame 12 and an adjusting mechanism 13. The adjusting mechanism 13 includes a first mounting seat 132 and an adjusting rod 131. The first mounting seat 132 is mounted on the first frame 11 of the display screen. One end of the adjusting rod 131 is movably connected to the first mounting seat 132, and the other end of the adjusting rod 131 extends out of the first mounting seat 132 and is rotatably connected to the second frame 12 of the display screen. So that the first frame 11 can adjust the angle relative to the second frame 12 by the length of the extending adjusting rod 131, realizing the angle adjustment between the first frame 11 and the second frame 12, 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 flat screen, that is, after the display module 20 is mounted on the cabinet frame 10, it can be adaptively deformed under the control of the cabinet frame 10, so as to be able to cooperate with the cabinet frame 10 to form a corresponding curved screen or flat screen. The operation is simple, fast and can be applied to different application scenarios.

[0063] Exemplarily, the first frame 11 is connected to both sides of the second frame 12 through the adjusting mechanism 13. The control box 30 is arranged on the side of the second frame 12 facing away from the display module 20. The display module 20 is a bendable flexible structure and can adapt to the angle adjustment between the first frame 11 and the second frame 12, so that it can cooperate with the cabinet frame 10 to form a corresponding curved screen or flat screen. The operation is simple, fast and can be applied to different application scenarios.

[0064] Specifically, after the display module 20 is assembled to the cabinet frame 10, the cabinet frame 10 can adjust the angle formed between the second frame 12 and the first frame 11 through the adjusting mechanism 13 according to the structure of the display module 20, 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 flat screen, that is, after the display module 20 is mounted on the cabinet frame 10, it can be adaptively deformed under the control of the cabinet frame 10, so as to be able to cooperate with the cabinet frame 10 to form a corresponding curved screen or flat screen. It has the characteristics of reliable structure, high stability and more convenient adjustment, and can be applied to different application scenarios.

[0065] After adopting the above technical solution, since the first frame 11 can freely adjust the angle formed between it and the second frame 12 through the adjusting mechanism 13, the display screen after the cabinet frame 10 and the display module 20 are assembled can form a corresponding curved screen or a flat screen, and the shape of the curved screen can be adjusted by the adjusting mechanism 13 according to the shape of the display module 20, with simple and quick operation. Since the cabinet frame 10 and the display module 20 can be adjusted into a shape adapted to the display module 20 through the adjusting mechanism 13 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 13 has flexibility and randomness, so that arbitrary special-shaped large-screen displays such as S-shaped or C-shaped can be formed, which can be applied to different application scenarios.

[0066] In an alternative embodiment, a first mounting portion 111 is provided on the first frame 11, a second mounting portion 121 is provided on the second frame 12, the first mounting seat 132 is mounted on the first mounting portion 111, and the adjusting rod 131 is rotatably connected to the second mounting portion 121 through a connecting pin 1313. Among them, the first mounting portion 111 can be a rib structure on the first frame 11, which is connected to opposite sides of the first frame 11, and can not only be used to strengthen the strength of the first frame 11, but also be used for the fixation of the first mounting portion 111, so that the first frame 11 can be connected to the second frame 12; similarly, the second mounting portion 121 can be a boss structure on the second frame 12, and the boss structure can be fixed to the first frame 11 by welding or integral molding. The connecting pin 1313 passes through the end of the adjusting rod 131 and is rotatably connected to the shaft hole of the second mounting portion 121, so that when the length of the adjusting rod 131 is extended or shortened, the first frame 11 can be pushed to rotate around the shaft hole of the second mounting portion 121 to form a controllable angle, realizing the angle adjustment between the first frame 11 and the second frame 12, breaking through the fixed limitation of the structure of the traditional cabinet frame 10, so that the dynamic deformation of the cabinet frame 10 can be realized through the mechanical adjusting mechanism 13, which has significant application value in the fields of large LED display screens, deformable billboards, etc.

[0067] In an alternative embodiment, as Figure 2 、 Figures 5 to 6As shown, the adjusting mechanism 13 further includes a cabinet handle 135. One end of the cabinet handle 135 is connected to the first mounting seat 132, and the other end of the cabinet handle 135 is fixed on the first frame 11. When the angle of the display screen is adjusted or installed, the operator can hold the cabinet handle 135 to adjust the rotation angle of the first frame 11 relative to the second frame 12, so that the adjusting rod 131 can be adjusted to a preset length without additional tools. At the same time, the dynamic load during the adjustment process can be dispersed to the handle, extending the service life of the mechanism; or when the length of the adjusting rod 131 is fixed, the operator can hold the cabinet handle 135 to install or carry the display screen, which is used to bear the weight of the display screen and improve the efficiency.

[0068] Exemplarily, when the cabinet frame 10 needs to adjust the angle formed by the first frame 11 relative to the second frame 12, control the length of the adjusting rod 131 extending out of the cabinet handle 135, so that the first frame 11 can rotate relative to the second frame 12. When the first frame 11 rotates to the required angle, fix the extending length of the adjusting rod 131 to prevent the first frame 11 from freely rotating relative to the second frame 12. The operation is simple and fast, and it can be applied to different application scenarios.

[0069] In an alternative embodiment, the cabinet handle 135 includes a grip portion and a first connection seat. One end of the grip portion is fixed on the rib structure through the first connection seat and is spaced from the first mounting seat 132, and the other end of the grip portion is connected to the first mounting seat 132. Wherein, the first mounting seat 132 includes a seat body and a second connection seat fixed on the rib structure. The other end of the grip portion is connected to one of the second connection seats, and both sides of the seat body are rotatably connected to the second connection seat, so that the adjusting rod 131 can be rotatably connected to the second connection seat through the seat body, so that when the adjusting rod 131 adjusts the length extending out of the cabinet handle 135, the adjusting rod 131 can rotate relative to the second connection seat through the first mounting seat 132.

[0070] In an alternative embodiment, the cabinet handle 135 includes a gasket, and the gasket is installed on the rotating shaft of the second connection seat and is located between the second connection seat and the first mounting seat 132.

[0071] In an alternative embodiment, as Figure 2 、 Figures 5 to 8As shown in the figure, the seat body includes a first seat body 1321 and a second seat body 1322. The first seat body 1321 and the second seat body 1322 are buckled with each other to form a movable slot 1323. The adjusting rod 131 is slidably installed in the movable slot 1323 so that the length of the adjusting rod 131 extending out of the movable slot 1323 can be adjusted to realize the angle adjustment between the first frame 11 and the second frame 12, enabling the display screen to form a corresponding curved screen or straight screen. The operation is simple and fast, solving the problem of 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.

[0072] In an alternative embodiment, as Figure 2 , Figure 5 , Figure 6 and Figure 12 shown, the adjusting mechanism 13 further includes an unlocking component 133. The unlocking component 133 is arranged on the first mounting seat 132 and is used to lock or unlock the length of the adjusting rod 131 extending out of the first mounting seat 132 to control the included angle between the first frame 11 and the second frame 12, further improving the convenience and stability of the angle adjustment of the box body frame 10. After unlocking, the box body handle 135 can be pushed and pulled with one hand to change the connection length of the adjusting rod 131, which is suitable for frequent adjustment in exhibitions; in the locked state, it can withstand external force impacts to prevent accidental angle deviation, such as wind vibration outdoors.

[0073] Exemplarily, when the box body frame 10 needs to adjust the angle formed by the first frame 11 relative to the second frame 12, the unlocking component 133 is operated to unlock the adjusting rod 131 from the first mounting seat 132, and then the length of the adjusting rod 131 extending out of the first mounting seat 132 is controlled so that the first frame 11 can rotate relative to the second frame 12. When the first frame 11 rotates to the required angle, the adjusting rod 131 is locked with the first mounting seat 132 through the unlocking component 133 to prevent the first frame 11 from rotating freely relative to the second frame 12. The operation is simple and fast and can be applied to different application scenarios.

[0074] In an alternative embodiment, the unlocking component 133 includes a button 1332 and a limit block 1331. The limit block 1331 is provided with adjusting teeth 13311, and the adjusting teeth 13311 are used to engage or disengage with the rack structure 1312 on the adjusting rod 131 to realize precise locking and instant release of the length of the adjusting rod 131.

[0075] In an alternative embodiment, a limiting block 1331 groove is provided on the first mounting seat 132. The limiting block 1331 is movably installed in the limiting block 1331 groove. The button 1332 is connected to the limiting block 1331 and is used to drive the adjusting tooth 13311 to engage with or disengage from the rack structure 1312. Among them, the shapes of the limiting block 1331 groove and the limiting block 1331 are both square structures to limit the rotation of the limiting block 1331 relative to the mounting seat during the pressing process of the button 1332, playing a limiting role.

[0076] In an alternative embodiment, the unlocking assembly 133 further includes an elastic member 1333. The elastic member 1333 always maintains an elastic force in the direction of the limiting block 1331 to drive the adjusting tooth 13311 to abut against the rack structure 1312. While ensuring the locking accuracy of the unlocking assembly 133, it also takes into account the operation convenience, improving the automatic reset ability and operation reliability of the unlocking assembly 133.

[0077] In an alternative embodiment, as Figure 2 、 Figure 6 、 Figure 7 and Figure 11 shown, the adjusting rod 131 includes a connecting rod 1311 and a rack structure 1312. The two ends of the connecting rod 1311 are respectively connected to the first mounting seat 132 and the second frame 12. The rack structure 1312 is arranged on the connecting rod 1311 to limit the extending length of the adjusting rod 131. While ensuring mechanical reliability, it can not only provide a length adjustment accuracy of millimeter level, but also set the connecting rod 1311 and the rack structure 1312 into different materials, realizing a rigid-flexible structure configuration of the adjusting rod 131. For example, the connecting rod 1311 is made of aluminum alloy or plastic material, and the rack structure 1312 is made of stainless steel material.

[0078] Exemplarily, a first groove 131a is provided along the length direction of the connecting rod 1311. The rack structure 1312 is detachably installed in the first groove 131a, improving the maintainability, modularity and environmental adaptability of the adjusting mechanism 13. On the premise of ensuring mechanical performance, the maintenance cost and downtime are greatly reduced.

[0079] In an alternative embodiment, a limiting groove 131b is provided on the connecting rod 1311. A limiting column is installed in the seat body of the first mounting seat 132. The limiting column cooperates with the limiting groove 131b to limit the sliding distance of the connecting rod 1311 relative to the first mounting seat 132, so as to accurately control the sliding stroke of the connecting rod 1311 through the mechanical hard limiting structure, avoid the separation of the connecting rod 1311 from the first mounting seat 132, and also ensure the reliability and safety of the adjusting mechanism 13.

[0080] In an alternative embodiment, as Figure 2 , Figures 6 to 10 shown, the adjusting mechanism 13 includes a damping structure 1324. The damping structure 1324 is disposed on the first mounting seat 132 and is used to cooperate with the rack structure 1312 to achieve precise control of the movement resistance of the adjusting rod 131, so as to add a flexible damping adjustment function on the basis of mechanical limit, which not only meets the precise positioning requirements but also avoids rigid impact damage to the structure.

[0081] In an alternative embodiment, as Figure 2 , Figures 6 to 8 shown, the adjusting mechanism 13 includes a shrapnel structure 13241. One end of the shrapnel structure 13241 is mounted on the first mounting seat 132, and the other end of the shrapnel structure 13241 is clamped with the rack structure 1312, which is used to limit the free movement of the rack structure 1312 and can also increase the feel when the adjusting rod 131 adjusts its length.

[0082] In an alternative embodiment, the first mounting seat 132 includes a friction block 13242. A receiving groove is provided on the seat body of the first mounting seat 132. The friction block 13242 is mounted in the receiving groove and abuts against the end face of the connecting rod 1311, and it will not break due to long-term abutment with the rack structure 1312. At the same time, wear indication lines can be provided on the friction block 13242 to facilitate the replacement of the friction block 13242. Among them, the receiving groove can adopt a pull-out structure design, that is, the connecting rod 1311 does not need to be disassembled during the process of replacing the friction block 13242. In addition, the friction block 13242 of the present application can also be applied with an elastic force through a spring structure to push the friction block 13242 towards the side of the rack structure 1312, so that the friction block 13242 can increase the pressing force applied to the rack structure 1312 through the spring structure as the wear amount increases.

[0083] In an alternative embodiment, the friction block 13242 is provided with a protruding portion having a triangular cross-section, and the angle of the protruding portion is greater than the angle of the meshing teeth of the rack structure 1312, so that the sliding of the connecting rod 1311 is smoother and has movement feedback.

At least part of the cylindrical bar 1314 is received in the groove portions 131c for sliding connection with both sides of the first mounting seat 132, ensuring the stability of the adjusting rod 131 during adjustment without smoothness and jamming. This not only improves the mechanical durability and movement smoothness of the adjusting rod 131 but also greatly enhances the convenience during operation. The overall structure is simple and very convenient to operate.

[0085] In an alternative embodiment, the first mounting seat 132 includes a seat body and a pin shaft 1327 disposed in the seat body. The pin shaft 1327 has an arc-shaped groove matching the cylindrical bar 1314, and a part of the cylindrical bar 1314 is slidably connected in the arc-shaped groove, which can not only assist the movement and guiding of the adjusting rod 131 but also reduce the friction between the cylindrical bar 1314 and the seat body, achieving precise guiding of the movement trajectory of the adjusting rod 131 and optimized load distribution.

[0086] In an alternative embodiment, the first mounting seat 132 further includes a bearing member 1325. The bearing member 1325 is rotatably mounted in the seat body of the first mounting seat 132 and contacts two end faces opposite to the connecting rod 1311, making the sliding of the adjusting rod 131 relative to the first mounting seat 132 smoother when adjusting the radian between the first frame 11 and the second frame 12. While maintaining the adjustment accuracy, it also ensures the service life of the adjusting rod 131, achieving multi-dimensional mechanical optimization of the adjusting mechanism 13.

[0087] In an alternative embodiment, a connecting shaft 1326 is connected between the first seat body 1321 and the second seat body 1322. The bearing member 1325 is rotatably mounted on the connecting shaft 1326, so as to reduce the manufacturing cost of the first mounting seat 132 through the split design of the first mounting seat 132. At the same time, the through-type connecting shaft 1326 can be used to connect the first seat body 1321 and the second seat body 1322 together and install the bearing member 1325 in the connecting shaft 1326 to cooperate with the use of the adjusting rod 131, making the sliding of the adjusting rod 131 relative to the first mounting seat 132 smoother.

A scale is provided on the front surface of the connecting rod 1311, and a feedback hole 13111 corresponding to the scale is provided on the back surface of the connecting rod 1311. The feedback member cooperates with the feedback hole 13111 to form a signal indicator for the in-place reminder function.

[0089] Exemplarily, the distance between two adjacent feedback holes 13111 corresponds to five scale values on the scale, so that when the adjusting rod 131 adjusts its length, the feedback member can cooperate with each feedback hole 13111 on the adjusting rod 131 to perform a position - in - place reminder function, preventing the adjusting rod 131 from being too long or too short during length adjustment, and thus better controlling the length of the adjusting rod 131 extending out of the movable slot 1323.

[0092] In an alternative embodiment, the limiting assembly 134 includes a second mounting seat 1342 and a limiting rod 1341 with a steep slope surface 134a. The limiting rod 1341 is rotatably installed on the second frame 12 through the second mounting seat 1342, so that the steep slope surface 134a can abut against the adjusting rod 131 during the rotation of the limiting rod 1341, realizing the locking function of the adjusting rod 131, and making the adjusting rod 131 not easy to slide or shake when in the locked state. Among them, during the rotation of the limiting rod 1341, a slope - surface sliding is formed between the steep slope surface 134a and the adjusting rod 131, that is, the limiting rod 1341 can slowly hold against the adjusting rod 131 and realize the locking function, which can not only make the adjusting rod 131 stay at any position, but also avoid damage to the limiting assembly 134 during the adjustment process.

[0093] In an alternative embodiment, the limiting rod 1341 includes a limiting protrusion. The limiting protrusion has a flat surface 134c, a gentle slope surface 134b and a steep slope surface 134a. The flat surface 134c is smoothly and transitionally connected to the steep slope surface 134a through the gentle slope surface 134b, so that the limiting protrusion can switch between the flat surface 134c and the steep slope surface 134a through the gentle slope surface 134b to limit or release the movement of the adjusting rod 131.

[0094] In an alternative embodiment, the limiting rod 1341 further has a first limiting surface 134e and a second limiting surface 134f. The first limiting surface 134e and the second limiting surface 134f are arranged adjacent to each other and are used to limit the positions of the flat surface 134c and the steep slope surface 134a to prevent misoperation.

[0095] In an alternative embodiment, an arc surface structure is connected between the first limiting surface 134e and the second limiting surface 134f, so that the retaining member arranged on the second mounting seat 1342 can be switched from the first limiting surface 134e to the second limiting surface 134f. Wherein, the retaining member cooperates with the first limiting surface 134e and the second limiting surface 134f to limit the positions of the flat surface 134c and the steep slope surface 134a.

[0096] In an alternative embodiment, as Figures 1 to 4 、 Figure 15 and Figure 16 shown, the box frame 10 further includes a connecting structure 14. Both ends of the first frame 11 are respectively rotatably connected to the second frame 12 through the connecting structure 14, and the adjusting mechanism 13 is connected to the middle parts of the first frame 11 and the second frame 12 to realize the rotational connection between the first frame 11 and the second frame 12 and enable corresponding radian adjustment through the adjusting mechanism 13.

The operation is simple and fast, and it can be applied to different application scenarios.

[0098] Specifically, when the box body frame 10 needs to adjust the angle formed by the first frame 11 relative to the second frame 12, operate the unlocking component 133 to unlock the adjusting rod 131 from the first mounting seat 132, and then control the length of the adjusting rod 131 extending out of the first mounting seat 132, so that the first frame 11 can rotate relative to the second frame 12 through the connecting structure 14. When the first frame 11 rotates to the required angle, use the unlocking component 133 to lock the adjusting rod 131 with the first mounting seat 132 to prevent the first frame 11 from freely rotating relative to the second frame 12. At the same time, control the limiting component 134 to make the steep slope surface 134a abut against the adjusting rod 131, realizing the locking function of the adjusting rod 131, so that the adjusting rod 131 is not easy to slide or shake when in the locked state. The operation is simple and fast, and it can be applied to different application scenarios.

[0099] In an alternative embodiment, the connecting structure 14 includes a first connecting block 141 and a second connecting block 142.

The two ends of the reset member 153 are respectively abutted against the fixing base 151 and the protection piece 152, and are used to always maintain an elastic force in the direction away from the fixing base 151, so as to drive the protection piece 152 to move away from the fixing base, and further protect the display module 20 mounted on the box frame 10, and avoid damage to the display module 20 during disassembly or transportation.

[0105] Exemplarily, fixing grooves and avoiding grooves are provided on the first frame 11, and the fixing base 151 is fixed in the fixing posts in the fixing grooves. Among them, a connecting boss 1522 and a guiding boss 1521 are provided on the protection piece 152, and avoiding grooves are provided on the outer side walls of the second frame 12. The connecting shaft 154 passes through the connecting boss 1522 and is connected to the guiding groove 1512.

[0106] In an alternative embodiment, a guiding inclined surface 1513 and an inclined surface groove 1511 are provided on the fixing base 151. One end of the reset member 153 is mounted 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 protection piece 152 to move away from the fixing base 151. Among them, the inclination angle of the guiding inclined surface 1513 is the same as the inclination angles of the inclined surface groove 1511 and the guiding groove 1512, so that the fixing base 151 can be obliquely mounted in the fixing groove along the guiding inclined surface 1513, to ensure the parallelism between the protection piece and the outer side walls of the second frame 12 and the third frame, and at the same time, the protection piece can also move along the guiding direction of the guiding groove through the guiding boss and retract into the avoiding groove.

[0107] Exemplarily, the first frame has opposite first and second corners, and the protection structure 15 is mounted thereon. When two box frames are spliced, the protection pieces move toward the opposite directions of the two box frames and exert external forces on each other, so that the protection pieces can retract into the first frame, and the two box frames can be well spliced together.

[0112] In an alternative embodiment, the module bottom shell 21 includes a plurality of shells arranged in sequence along a first direction, and at least a limiting component 23 is connected between adjacent two shells. The limiting component 23 is used to limit the amount of deformation when the module bottom shell 21 undergoes a bending deformation, avoid damage to the display module 20 caused by excessive deformation of the module bottom shell 21, and ensure the normal use of the display module 20.

[0113] Exemplarily, the shell includes a first shell 21a and a second shell 21b. A part of the structure of the limiting component 23 is formed on the first shell 21a, and another part of the structure of the limiting component 23 is formed on the second shell 21b. When the display surface of the display module 20 is concave and the amount of deformation reaches the maximum, that is, the display module 20 is bent into a U-shaped structure, at this time the limiting component 23 can form a limit to limit the relative displacement amount between the first shell 21a and the second shell 21b, so that the module bottom shell 21 no longer undergoes more deformation, avoid damage to the display module 20 caused by excessive deformation of the module bottom shell 21, and ensure the normal use of the display module 20.

[0114] Or, when the display surface of the display module 20 is convex and the amount of deformation reaches the maximum, that is, the display module 20 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 shell 21a and the second shell 21b, so that the module bottom shell 21 no longer undergoes more deformation, avoid damage to the display module 20 caused by excessive deformation of the module bottom shell 21, and ensure the normal use of the display module 20.

[0115] After adopting the above technical solution, since the flexible module bottom shell 21 is prone to damage the display module 20 due to excessive deformation during transportation or assembly.

[0118] Exemplarily, when the display surface of the display module 20 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 restrict the relative displacement amount between the first shell and the second shell, so that the module bottom shell no longer undergoes more deformation, avoid damage to the display module 20 due to excessive deformation of the module bottom shell, and ensure that the display module 20 can be used normally.

[0119] Or, when the display surface of the display module 20 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 shell; 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 shell, which is used to restrict the relative displacement amount between the first shell and the second shell, so that the module bottom shell no longer undergoes more deformation, avoid damage to the display module 20 due to excessive deformation of the module bottom shell, and ensure that the display module 20 can be used normally.
