[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0039] It should also be understood that the terminology used in this utility model specification is merely for describing specific aspects of the present application. It is important to understand that terms such as "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0040] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0041] like Figures 1 to 3 As shown, this application provides a display screen, including a display module 20, a cabinet frame 10, and a control box 30. The display module 20 is mounted on the cabinet frame 10, and the control box 30 is disposed on the side of the cabinet frame 10 facing away from the display module 20 and is electrically connected to the display module 20 for transmitting electrical signals, such as power supply or other data.

[0042] In one optional embodiment, the control box 30 includes a box body, a battery assembly, a communication module, and a control card. The box body has a cavity, and the communication module and control card are disposed within the cavity of the box body. The battery assembly is connected to the box body and enclosed within the cavity of the box body. A mounting groove is formed on the housing frame 10, and the box body is mounted in the mounting groove.

[0043] In an optional implementation, the battery assembly, communication module, and control card are electrically connected, and the control card is electrically connected to the display module 20. The battery assembly provides power to the control card, wireless communication module, and display module 20. 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 and process the communication data transmitted by the communication module and control the display operation of the display module 20 based on the processing result.

[0044] In one alternative implementation, such as Figures 2 to 5As shown, the cabinet frame 10 includes a first frame 11, a second frame 12, and an adjustment mechanism 13. The adjustment mechanism 13 includes a first mounting base 132 and an adjustment rod 131. The first mounting base 132 is mounted on the first frame 11 of the display screen. One end of the adjustment rod 131 is movably connected to the first mounting base 132, and the other end of the adjustment rod 131 extends out of the first mounting base 132 and is rotatably connected to the second frame 12 of the display screen. This allows the first frame 11 to adjust its angle relative to the second frame 12 by adjusting the length of the extension of the adjustment rod 131, thereby achieving angle adjustment between the first frame 11 and the second frame 12. This enables the display module 20 mounted on the cabinet frame 10 to cooperate with the cabinet frame 10 to form a corresponding curved screen or a straight screen. In other words, after the display module 20 is mounted on the cabinet frame 10, it can adapt and deform under the control of the cabinet frame 10, thus cooperating with the cabinet frame 10 to form a corresponding curved screen or a straight screen. The operation is simple and quick, and it can be applied to different application scenarios.

[0045] For example, the first frame 11 is connected to both sides of the second frame 12 through the adjustment mechanism 13. The control box 30 is set on the side of the second frame 12 that faces away from the display module 20. The display module 20 is a flexible structure that can bend and adapt to the angle adjustment of the first frame 11 and the second frame 12. Thus, it can work together with the cabinet frame 10 to form a corresponding curved screen or straight screen. It is easy and quick to operate and can be applied to different application scenarios.

[0046] Specifically, after the display module 20 is assembled into the cabinet frame 10, the cabinet frame 10 can adjust the angle between the second frame 12 and the first frame 11 through the adjustment mechanism 13 according to the structure of the display module 20. This allows the display module 20 installed on the cabinet frame 10 to cooperate with the cabinet frame 10 to form a corresponding curved screen or straight screen. In other words, after the display module 20 is installed in the cabinet frame 10, it can undergo adaptive deformation under the control of the cabinet frame 10 so as to cooperate with the cabinet frame 10 to form a corresponding curved screen or straight screen. It has the characteristics of reliable structure, high stability, and more convenient adjustment, and can be applied to different application scenarios.

[0047] After adopting the above technical solution, since the first frame 11 can freely adjust the angle between itself and the second frame 12 through the adjustment mechanism 13, the display screen after the cabinet frame 10 and the display module 20 are assembled can form a corresponding curved screen or straight screen. Moreover, the shape of the curved screen can be adjusted according to the shape of the display module 20 through the adjustment mechanism 13, which is simple and quick to operate. Since the cabinet frame 10 and the display module 20 can be adjusted to a shape that matches the display module 20 after assembly through the adjustment mechanism 13, a single display unit can present a curved structure. Then, multiple curved display units can be spliced ​​together to form a large display with a true curved form. In addition, the adjustment angle of the adjustment mechanism 13 is flexible and arbitrary, so that any irregularly shaped large screen display such as S-shape or C-shape can be formed, which can be applied to different application scenarios.

[0048] In one optional embodiment, a first mounting part 111 is provided on the first frame 11, a second mounting part 121 is provided on the second frame 12, a first mounting seat 132 is mounted on the first mounting part 111, and an adjusting rod 131 is rotatably connected to the second mounting part 121 through a connecting pin 1313. The first mounting part 111 can be a rib structure on the first frame 11, which is connected to the opposite sides of the first frame 11. It can not only strengthen the strength of the first frame 11, but also fix the first mounting part 111, so that the first frame 11 can be connected to the second frame 12. Similarly, the second mounting part 121 can be a boss structure on the second frame 12. 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 part 121, so that when the length of the adjusting rod 131 is extended or shortened, it can push the first frame 11 to rotate around the shaft hole of the second mounting part 121 to form a controllable included angle, thereby realizing the angle adjustment between the first frame 11 and the second frame 12. This breaks through the fixed limitation of the traditional box frame 10 structure, so that the dynamic deformation of the box frame 10 can be realized through the mechanical adjustment mechanism 13. It has significant application value in the fields of large LED display screens and deformable billboards.

[0049] In one alternative implementation, such as Figure 2 , Figures 5 to 6As shown, the adjustment mechanism 13 also includes a cabinet handle 135. One end of the cabinet handle 135 is connected to the first mounting base 132, and the other end of the cabinet handle 135 is fixed to the first frame 11. When 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 adjustment rod 131 can be adjusted to the preset length without additional tools. At the same time, the dynamic load during the adjustment process can be distributed to the handle, extending the service life of the mechanism. Alternatively, when the length of the adjustment rod 131 is fixed, the operator can hold the cabinet handle 135 to install or move the display screen to support the weight of the display screen and improve efficiency.

[0050] For example, when the box frame 10 needs to adjust the angle between the first frame 11 and the second frame 12, the length of the extension of the adjusting rod 131 from the box handle 135 is controlled so that the first frame 11 can rotate relative to the second frame 12. After the first frame 11 rotates to the required angle, the extension length of the adjusting rod 131 is fixed to prevent the first frame 11 from rotating freely relative to the second frame 12. The operation is simple and quick and can be applied to different application scenarios.

[0051] In one optional embodiment, the case handle 135 includes a grip portion and a first connecting seat. One end of the grip portion is fixed to the rib structure via the first connecting seat and spaced apart from the first mounting seat 132. The other end of the grip portion is connected to the first mounting seat 132. The first mounting seat 132 includes a base and a second connecting seat fixed to the rib structure. The other end of the grip portion is connected to one of the second connecting seats. Both sides of the base are rotatably connected to the second connecting seats, allowing the adjusting rod 131 to be rotatably connected to the second connecting seats via the base, so that when adjusting the length of the extended case handle 135, the adjusting rod 131 can rotate relative to the second connecting seats via the first mounting seat 132.

[0052] In an alternative embodiment, the housing handle 135 includes a gasket mounted on the pivot of the second connector and located between the second connector and the first mounting base 132.

[0053] In one alternative implementation, such as Figure 2 , Figures 5 to 8As shown, the base includes a first base 1321 and a second base 1322. The first base 1321 and the second base 1322 are interlocked to form a movable groove 1323. An adjusting rod 131 is slidably installed in the movable groove 1323 so that the angle between the first frame 11 and the second frame 12 can be adjusted by adjusting the length of the adjusting rod 131 extending out of the movable groove 1323. This allows the display screen to form a curved screen or a straight screen, which is simple and quick to operate. It solves the problem of the display screen being used in a relatively simple way, meets the splicing requirements of conventional screens and irregular screens, and enables the display screen to be applied to different application scenarios.

[0054] In one alternative implementation, such as Figure 2 , Figure 5 , Figure 6 and Figure 12 As shown, the adjustment mechanism 13 also includes an unlocking component 133, which is mounted on the first mounting base 132 and is used to lock or unlock the length of the adjustment rod 131 extending out of the first mounting base 132 to control the angle between the first frame 11 and the second frame 12. This further improves the convenience and stability of the angle adjustment of the box frame 10. After unlocking, the angle can be changed by pushing and pulling the adjustment rod 131 with one hand, which is suitable for frequent adjustments at exhibitions. In the locked state, it can withstand external impacts and prevent accidental angle deviation, such as outdoor wind vibration.

[0055] For example, when the housing frame 10 needs to adjust the angle between the first frame 11 and the second frame 12, the unlocking component 133 is operated to unlock the adjusting rod 131 from the first mounting base 132. Then, the adjusting rod 131 is controlled to extend beyond the length of the first mounting base 132, allowing the first frame 11 to rotate relative to the second frame 12. When the first frame 11 rotates to the required angle, the unlocking component 133 locks the adjusting rod 131 to the first mounting base 132 to prevent the first frame 11 from rotating freely relative to the second frame 12. The operation is simple and quick, and can be applied to different application scenarios.

[0056] In an optional embodiment, the unlocking component 133 includes a button 1332 and a limiting block 1331. The limiting block 1331 is provided with an adjusting tooth 13311, which is used to engage or disengage with the rack structure 1312 on the adjusting rod 131 to achieve precise locking and immediate release of the length of the adjusting rod 131.

[0057] In an optional embodiment, the first mounting base 132 is provided with a limiting block 1331 groove, the limiting block 1331 being movably installed in the limiting block 1331 groove, and the button 1332 being connected to the limiting block 1331 for driving the adjusting gear 13311 to engage or disengage with the rack structure 1312. Both the limiting block 1331 groove and the limiting block 1331 are square in shape to restrict the limiting block 1331 from rotating relative to the mounting base during the pressing process via the button 1332, thus providing a limiting function.

[0058] In an optional embodiment, the unlocking component 133 further includes an elastic element 1333, which 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. This ensures the locking accuracy of the unlocking component 133 while also taking into account the ease of operation, thereby improving the automatic reset capability and operational reliability of the unlocking component 133.

[0059] In one alternative implementation, such as Figure 2 , Figure 6 , Figure 7 and Figure 11 As shown, the adjusting rod 131 includes a connecting rod 1311 and a rack structure 1312. The two ends of the connecting rod 1311 are connected to the first mounting base 132 and the second frame 12, respectively. The rack structure 1312 is disposed on the connecting rod 1311 to limit the extension length of the adjusting rod 131. While ensuring mechanical reliability, it can not only provide millimeter-level length adjustment accuracy, but also make the connecting rod 1311 and the rack structure 1312 made of different materials, realizing a structural configuration of rigidity and flexibility 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.

[0060] For example, the connecting rod 1311 is provided with a first groove 131a along its length, and the rack structure 1312 is detachably installed in the first groove 131a, which improves the maintainability, modularity and environmental adaptability of the adjustment mechanism 13, and significantly reduces maintenance costs and downtime while ensuring mechanical performance.

[0061] In an optional embodiment, the connecting rod 1311 is provided with a limiting groove 131b, and a limiting post is installed in the seat of the first mounting base 132. The limiting post cooperates with the limiting groove 131b to limit the sliding distance of the connecting rod 1311 relative to the first mounting base 132. This allows for precise control of the sliding stroke of the connecting rod 1311 through a mechanical hard limiting structure, preventing the connecting rod 1311 from separating from the first mounting base 132 and ensuring the reliability and safety of the adjusting mechanism 13.

[0062] In one alternative implementation, such as Figure 2 , Figures 6 to 10 As shown, the adjustment mechanism 13 includes a damping structure 1324, which is mounted on the first mounting base 132 and is used to cooperate with the rack structure 1312 to achieve precise control of the movement resistance of the adjustment rod 131. This allows for the addition of flexible damping adjustment function on the basis of mechanical limit, which not only meets the requirements of precision positioning but also avoids rigid impact damage to the structure.

[0063] In one alternative implementation, such as Figure 2 , Figures 6 to 8 As shown, the adjustment mechanism 13 includes a spring structure 13241. One end of the spring structure 13241 is mounted on the first mounting base 132, and the other end of the spring structure 13241 is engaged with the rack structure 1312 to restrict the free movement of the rack structure 1312. At the same time, it can also increase the feel of the adjustment rod 131 when adjusting the length.

[0064] In an optional embodiment, the first mounting base 132 includes a friction block 13242. The base of the first mounting base 132 has a receiving groove. The friction block 13242 is installed in the receiving groove and abuts against the end face of the connecting rod 1311, preventing breakage due to prolonged contact with the rack structure 1312. Wear indicator lines can also be provided on the friction block 13242 for easy replacement. The receiving groove can be a pull-out design, allowing replacement of the friction block 13242 without disassembling the connecting rod 1311. Furthermore, the friction block 13242 can also be spring-loaded to push it towards one side of the rack structure 1312, allowing the spring structure to increase the clamping force applied to the rack structure 1312 as wear increases.

[0065] In an optional embodiment, the friction block 13242 is provided with a protrusion with a triangular cross-section. The angle of the protrusion 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.

[0066] In one alternative implementation, such as Figure 2 , Figures 9 to 11As shown, the adjusting rod 131 also includes a cylindrical strip 1314 made of wear-resistant material. The connecting rod 1311 has grooves 131c on both sides. At least a portion of the cylindrical strip 1314 is accommodated in the grooves 131c for sliding connection with both sides of the first mounting base 132. This ensures the stability of the adjusting rod 131 during adjustment and prevents any unevenness or jamming. This not only improves the mechanical durability and smoothness of the adjusting rod 131 but also greatly enhances the ease of operation. The overall structure is simple and very convenient to operate.

[0067] In an optional embodiment, the first mounting base 132 includes a base body and a pin 1327 disposed within the base body. The pin 1327 has an arcuate groove that matches the cylindrical bar 1314. A portion of the cylindrical bar 1314 is slidably connected in the arcuate groove, which not only assists in the movement and guidance of the adjusting rod 131, but also reduces the friction between the cylindrical bar 1314 and the base body, thereby achieving precise guidance of the movement trajectory of the adjusting rod 131 and optimized load distribution.

[0068] In an optional embodiment, the first mounting base 132 further includes a bearing 1325, which is rotatably mounted in the seat of the first mounting base 132 and contacts the upper and lower end faces of the connecting rod 1311. This allows the adjusting rod 131 to slide more smoothly relative to the first mounting base 132 when adjusting the curvature between the first frame 11 and the second frame 12. While maintaining the adjustment accuracy, this also ensures the service life of the adjusting rod 131, achieving multi-dimensional mechanical optimization of the adjusting mechanism 13.

[0069] In an optional embodiment, a connecting shaft 1326 connects the first base 1321 and the second base 1322, and a bearing 1325 is rotatably mounted on the connecting shaft 1326. This allows for a reduction in the manufacturing cost of the first mounting base 132 through its split design. Alternatively, a through-type connecting shaft 1326 can be used to connect the first base 1321 and the second base 1322 together and mount the bearing 1325 in the connecting shaft 1326. This facilitates the use of the adjusting rod 131, making the sliding of the adjusting rod 131 relative to the first mounting base 132 smoother.

[0070] In one alternative implementation, such as Figure 2 , Figures 5 to 7 As shown, the adjustment mechanism 13 includes a feedback element. The front of the connecting rod 1311 is provided with a scale, and the back of the connecting rod 1311 is provided with a feedback hole 13111 corresponding to the scale. The feedback element and the feedback hole 13111 cooperate to form a signal indicator so as to provide a positioning reminder function.

[0071] For example, the distance between two adjacent feedback holes 13111 corresponds to five scale values ​​on the scale, so that when the length of the adjusting rod 131 is adjusted, the feedback element can cooperate with each feedback hole 13111 on the adjusting rod 131 to provide a positioning reminder function, preventing the adjusting rod 131 from being too long or too short when adjusting the length, thereby better controlling the length of the adjusting rod 131 extending out of the movable slot 1323.

[0072] In an alternative embodiment, the feedback element includes a plunger or a glass ball, and the first mounting base 132 is provided with a plunger groove in which the plunger or glass ball is installed.

[0073] In one alternative implementation, such as Figure 2 , Figure 5 , Figure 13 and Figure 14 As shown, the adjustment mechanism 13 also includes a limiting component 134. The limiting component 134 is installed at the end of the adjustment rod 131 away from the first mounting base 132 and connected to the second frame 12. It is used to limit the relative position between the adjustment rod 131 and the second frame 12, forming a sliding lever structure. This allows the position between the adjustment rod 131 and the second frame 12 to remain unchanged, realize the force transmission during the arc adjustment, improve the stability of the display screen during adjustment, prevent the support from shifting or shaking during the adjustment process, achieve precise constraint of the motion terminal, avoid mechanical damage caused by over-adjustment, and ensure the adjustment effect of the display screen.

[0074] In an optional embodiment, the limiting component 134 includes a second mounting base 1342 and a limiting rod 1341 with a steep slope surface 134a. The limiting rod 1341 is rotatably mounted on the second frame 12 via the second mounting base 1342, so that the steep slope surface 134a can abut against the adjusting rod 131 during the rotation of the limiting rod 1341, thereby achieving the locking function of the adjusting rod 131 and making it less prone to sliding or shaking when the adjusting rod 131 is in the locked state. During the rotation of the limiting rod 1341, a slope sliding occurs between the steep slope surface 134a and the adjusting rod 131, meaning that the limiting rod 1341 can slowly press against the adjusting rod 131 and achieve the locking function. This not only allows the adjusting rod 131 to stop at any position but also prevents damage to the limiting component 134 during adjustment.

[0075] In an optional embodiment, the limiting rod 1341 includes a limiting protrusion having a flat surface 134c, a gentle slope surface 134b, and a steep slope surface 134a. The flat surface 134c is smoothly connected to the steep slope surface 134a via the gentle slope surface 134b, so that the limiting protrusion can switch between the flat surface 134c and the steep slope surface 134a via the gentle slope surface 134b, in order to limit or release the movement of the adjusting rod 131.

[0076] In an optional 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 being arranged adjacent to each other to limit the position of the flat surface 134c and the steep slope surface 134a, and to prevent misoperation.

[0077] In an optional embodiment, an arc-shaped structure connects the first limiting surface 134e and the second limiting surface 134f, allowing the retaining member disposed on the second mounting base 1342 to switch from the first limiting surface 134e to the second limiting surface 134f. The retaining member cooperates with the first limiting surface 134e and the second limiting surface 134f to limit the positions of the straight surface 134c and the steep slope surface 134a.

[0078] In one alternative implementation, such as Figures 1 to 4 , Figure 15 and Figure 16 As shown, the box frame 10 also includes a connecting structure 14. The two ends of the first frame 11 are rotatably connected to the second frame 12 through the connecting structure 14. The adjusting mechanism 13 is connected to the middle of the first frame 11 and the second frame 12 to realize the rotatable connection between the first frame 11 and the second frame 12 and to make corresponding arc adjustment through the adjusting mechanism 13.

[0079] For example, the first frame 11 has a first end 112 at both ends, and the second frame 12 has a second end 122 at both ends. The two first ends 112 are rotatably connected to the two second ends 122 through the connecting structure 14. The first mounting part 111 is disposed between the two first ends 112, and the second mounting part 121 is disposed between the two second ends 122. The first mounting base 132 and the cabinet handle 135 are installed in the first mounting part 111, and the second mounting base 1342 is installed on the second mounting part 121. The adjusting rod 131 is rotatably connected to the second mounting part 121 through the connecting pin 1313, so that the adjusting mechanism 13 can adjust the angle between the first frame 11 and the second frame 12, so that the display module 20 installed on the cabinet frame 10 can cooperate with the cabinet frame 10 to form a corresponding curved screen or straight screen. That is, after the display module 20 is installed on the cabinet frame 10, it can adapt and deform under the control of the cabinet frame 10 so that it can cooperate with the cabinet frame 10 to form a corresponding curved screen or straight screen. The operation is simple and quick, and it can be applied to different application scenarios.

[0080] Specifically, when the box frame 10 needs to adjust the angle between the first frame 11 and the second frame 12, the unlocking component 133 is operated to unlock the adjusting rod 131 from the first mounting base 132. Then, the length of the adjusting rod 131 extending from the first mounting base 132 is controlled 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, the unlocking component 133 locks the adjusting rod 131 to the first mounting base 132 to prevent the first frame 11 from rotating freely relative to the second frame 12. At the same time, the limiting component 134 is controlled to make the steep slope surface 134a abut against the adjusting rod 131, thereby realizing the locking function of the adjusting rod 131. This makes the adjusting rod 131 less prone to sliding or shaking when locked, and the operation is simple and quick, which can be applied to different application scenarios.

[0081] In an optional embodiment, the connection structure 14 includes a first connecting block 141 and a second connecting block 142, the second connecting block 142 being slidably connected to the first connecting block 141, the first connecting block 141 being rotatably connected to the first frame 11, and the second connecting block 142 being rotatably connected to the second frame 12.

[0082] In an optional embodiment, one of the first connecting block 141 and the second connecting block 142 is provided with a groove 1412, and the other of the first connecting block 141 and the second connecting block 142 is provided with a sliding rod 1422, so that the first connecting block 141 can be slidably connected to the second connecting block 142 by the cooperation of the sliding rod 1422 and the groove 1412.

[0083] For example, the slide bar 1422 is a T-shaped platform structure, and the slide groove 1412 is a T-shaped groove structure. The T-shaped platform structure is slidably installed in the T-shaped groove structure.

[0084] In an optional embodiment, the connecting structure 14 includes a blocking member disposed at the open end 1413 of the slide groove 1412 to prevent the slide rod 1422 from separating from the slide groove 1412.

[0085] In one optional embodiment, the second connecting block 142 has a Z-shaped structure. The first connecting block 141 and the slide groove 1412 are provided with a first rotating shaft 1411 on the same side. The slide rod 1422 is disposed on the second connecting block 142. The second connecting block 142 is provided with a second rotating shaft 1421 on the side opposite to the slide rod 1422. The first rotating shaft 1411 is rotatably connected to the first frame 11, and the second rotating shaft 1421 is rotatably connected to the second frame 12.

[0086] In one alternative implementation, such as Figures 1 to 4As shown, the housing frame 10 also includes a protective structure 15, which includes a protective sheet, an elastic element 1333, and a fixed seat mounted on the first frame 11. The fixed seat is inclinedly provided with a guide groove, and the protective sheet has a connecting shaft 1326. The connecting shaft 1326 is slidably mounted in the guide groove. The two ends of the elastic element 1333 abut against the fixed seat and the protective sheet respectively, so as to always maintain an elastic force in the direction away from the fixed seat, so as to drive the protective sheet to move away from the fixed seat, thereby protecting the display module 20 mounted on the housing frame 10 and preventing the display module 20 from being damaged during disassembly or transportation.

[0087] For example, the first frame 11 is provided with a fixing groove and a clearance groove, and the fixing seat is fixed in the fixing column in the fixing groove. The protective sheet is provided with a connecting boss and a guide boss, and the outer walls of the second frame 12 and the third frame are provided with clearance grooves. The connecting shaft 1326 passes through the connecting boss and connects to the guide groove. The guide boss is used to cooperate with the clearance groove so that the protective sheet can move away from the display module 20 when subjected to compressive force, so that the two frame structures can be well spliced ​​together.

[0088] In an optional embodiment, the mounting base is provided with a guide ramp and a ramp groove. One end of the elastic element 1333 is installed in the ramp groove, and the other end of the elastic element 1333 abuts against the connecting shaft 1326, so that the connecting shaft 1326 can drive the protective plate to move away from the mounting base. The inclination angle of the guide ramp is the same as the inclination angle of the ramp groove and the guide slot, so that the mounting base can be installed at an angle in the mounting slot, ensuring the parallelism of the protective plate with the outer walls of the second frame 12 and the third frame. It also allows the protective plate to move along the guide direction of the guide slot via the guide boss and retract into the clearance slot.

[0089] For example, the first frame has a first side and a second side, and the protective structure 15 is installed on it. When the two box frames are spliced, the protective plate moves toward the relative direction of the two box frames and applies external force to each other, so that the protective plate can retract into the first frame, so that the two box frames can be spliced ​​together well.

[0090] In an optional embodiment, the housing frame 10 further includes a first positioning post 16 disposed on one side of the protective structure 15 for restricting the movement of the protective sheet.

[0091] For example, the housing frame 10 is provided with a movable hole communicating with the fixing groove, and the first positioning post 16 has an abutting end and a limiting end. The limiting end is used to cooperate with the protective sheet to restrict the protective sheet from moving away from the display module 20 and prevent the protective sheet from retracting. The abutting end is used to drive the limiting end to release the limiting of the protective sheet when the two housing frames 10 are spliced.

[0092] In an optional embodiment, the display module 20 includes a module base and a lamp plate with LEDs. Both the module base and the lamp plate are flexible, bendable structures. The lamp plate is disposed on the module base so that the display module 20 can form an arc-shaped display screen that cooperates with the housing frame 10.

[0093] In one optional embodiment, the module bottom shell has a first end face and a second end face, the first end face and the second end face are arranged opposite to each other, the lamp panel is mounted on the first end face, and the second end face is used to connect with the cabinet frame 10 so that the cabinet frame 10 can control the display module 20 to undergo adaptive deformation and jointly form a corresponding curved screen or straight screen.

[0094] In an optional embodiment, the module bottom shell includes a plurality of shells arranged sequentially along a first direction, and at least one limiting component 134 is connected between two adjacent shells. The limiting component 134 is used to limit the deformation of the module bottom shell when it undergoes bending deformation, so as to prevent the display module 20 from being damaged due to excessive deformation of the module bottom shell and to ensure that the display module 20 can be used normally.

[0095] For example, the housing includes a first housing and a second housing. One part of the structure of the limiting component 134 is formed on the first housing, and the other part of the structure of the limiting component 134 is formed on the second housing. When the display surface of the display module 20 is concave and the deformation reaches its maximum, that is, when the display module 20 is bent into a U-shaped structure, the limiting component 134 can form a limit to restrict the relative displacement between the first housing and the second housing, so that the bottom shell of the module will no longer undergo more deformation, and the display module 20 will not be damaged due to excessive deformation of the bottom shell of the module, thus ensuring that the display module 20 can be used normally.

[0096] Alternatively, when the display surface of the display module 20 bulges outward and the deformation reaches its maximum, that is, when the display module 20 is bent into an n-shaped structure, the limiting component 134 can form a limit to restrict the relative displacement between the first shell and the second shell, so that the bottom shell of the module will no longer undergo more deformation, thus preventing the display module 20 from being damaged due to excessive deformation of the bottom shell of the module, and ensuring that the display module 20 can be used normally.

[0097] After adopting the above technical solution, due to the high flexibility of the module base shell, the display module 20 is easily damaged due to excessive deformation during transportation or assembly. Therefore, this application limits the deformation of the module base shell during bending deformation through the limiting component 134, thereby avoiding the risk of damage to the display module 20 due to excessive bending deformation of the module base shell during transportation or assembly, and ensuring that the display module 20 can be used normally.

[0098] In an optional embodiment, the limiting component 134 includes a first limiting part and a second limiting part. The first limiting part is formed on one of the two adjacent housings, and the second limiting part is formed on the other of the two adjacent housings. The first limiting part and the second limiting part cooperate to limit the relative displacement between the two adjacent housings, so as to prevent the display module 20 from being damaged due to excessive deformation of the module bottom shell and ensure that the display module 20 can be used normally.

[0099] In an optional embodiment, the first limiting part has a first abutting part, and the second limiting part has a second abutting part. When the bottom shell of the module undergoes bending deformation, the first abutting part abuts against the second abutting part or the end opposite to the second abutting part, so that the bottom shell of the module does not undergo further deformation. This can prevent the display module 20 from being damaged due to excessive deformation of the bottom shell of the module, and ensure that the display module 20 can be used normally.

[0100] For example, when the display surface of the display module 20 is concave and the deformation reaches its maximum, the first abutting part and the second abutting part abut together to form a limit, which is used to limit the relative displacement between the first housing and the second housing, so that the bottom shell of the module will no longer undergo more deformation, avoid damage to the display module 20 due to excessive deformation of the bottom shell of the module, and ensure that the display module 20 can be used normally.

[0101] Alternatively, when the display surface of the display module 20 bulges outward and the deformation reaches its maximum, the ends of the first abutting part and the second abutting part that are opposite to each other abut against each other, that is, the first abutting part abuts against the side wall of the second housing; the ends of the second abutting part and the first abutting part that are opposite to each other abut against each other, that is, the second abutting part abuts against the side wall of the first housing, are used to limit the relative displacement between the first housing and the second housing, so that the bottom shell of the module will no longer undergo more deformation, avoid damage to the display module 20 due to excessive deformation of the bottom shell of the module, and ensure that the display module 20 can be used normally.

[0102] In an optional embodiment, the first limiting part has a first connecting part, and the second limiting part has a second connecting part. The first abutting part is connected to the housing through the first connecting part and forms a first limiting groove 131b. The second abutting part is connected to the housing through the second connecting part and forms a second limiting groove 131b. The first abutting part moves in the second limiting groove 131b, and the second abutting part moves in the first limiting groove 131b. When the deformation of the display module 20 reaches its maximum, the first abutting part can form a limit with the two opposite end faces of the first limiting groove 131b, and the second abutting part can form a limit with the two opposite end faces of the second limiting groove 131b, so that the bottom shell of the module will no longer undergo more deformation, thereby preventing the display module 20 from being damaged due to excessive deformation of the bottom shell of the module, and ensuring that the display module 20 can be used normally.

[0103] In one optional embodiment, the first abutting portion and the first connecting portion are vertically connected, that is, the first abutting portion and the first connecting portion form an L-shaped structure.

[0104] In one optional 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.

[0105] It should be noted that the first limiting part and the second limiting part can also be constructed in other ways. Their main purpose is to limit the relative displacement between the first shell and the second shell. This application does not impose any restrictions on them.

[0106] In an optional embodiment, the display module 20 further includes a first connector and a second connector. The lamp board is connected to the module bottom shell on the side facing away from the lamp beads through the second connector. The first connector is used to cooperate with the second connector to realize the splicing of the module bottom shell in the second direction. This effectively solves the splicing problem between display modules 20 when splicing, improves the gap between display modules 20, and optimizes the display effect of the display screen.

[0107] In one optional embodiment, there are two second connectors. The first connector has a first connecting groove and a second connecting groove. The first connecting groove is connected to one of the second connectors of the display module 20, and the second connecting groove is connected to the second connector of the other display module 20. This allows the two display modules 20 to be spliced ​​together through the connection of the first connector and the second connector, solving the problem of seams between the display modules 20 when splicing them. This ensures that the displayed image maintains continuity and integrity, achieving seamless splicing of the display modules 20. Thus, while ensuring high-definition display, it solves the long-standing problem of bright and dark lines that may appear at the splicing points of the display modules 20.

[0108] It should be noted that the number of second connectors can be greater than two. The number of first and second connecting slots on the first connectors corresponds to the number of second connectors. At least one of the first and second connecting slots is used to connect with the connector of one of the two adjacent display modules 20. The remaining part of the first and second connecting slots is used to connect with the connector of the other of the two adjacent display modules 20, so as to achieve seamless splicing of the two adjacent display modules 20. This solves the long-standing problem of bright and dark lines at the splicing point of the two adjacent display modules 20 while ensuring high-definition display of the picture.

[0109] In one optional embodiment, the second connector includes a positioning copper post with a protruding surface connected to the back side of the lamp panel, and the end of the positioning copper post away from the protruding surface connected to the module bottom shell. Here, the back side of the lamp panel refers to the side of the lamp panel facing the module bottom shell.

[0110] In an alternative embodiment, the side of the module bottom shell is provided with an opening structure for the connector to pass through and to mate with a second connector on another module bottom shell.

[0111] In one optional embodiment, the first connector is provided with a first limiting member, and the module bottom shell is provided with a second limiting member. The first limiting member and the second limiting member cooperate to restrict the movement of the first connector relative to the module bottom shell.

[0112] In one optional embodiment, the first limiting member is a first groove disposed on the side of the first connector, and the second limiting member is a protrusion disposed on the bottom shell of the module. The first groove and the protrusion cooperate to limit the movement of the first connector relative to the bottom shell of the module. The bottom shell of the module and the first connector are provided with limiting strips at their left and right mating positions, and the protrusions are disposed on the limiting strips.

[0113] In one optional embodiment, the number of first grooves is at least two, and the two first grooves are spaced apart on the side of the first connector to limit the position of the first connector in the connected state and the non-connected state, that is, the position of the first connector inside the module bottom shell and the position of the first connector extending out of the module bottom shell and connecting with another module bottom shell.

[0114] In one optional embodiment, the first limiting member is an elastic protrusion disposed on the first connector, and the second limiting member is a second groove disposed on the module bottom shell. The elastic protrusion cooperates with the second groove to limit the movement of the first connector relative to the module bottom shell. The elastic protrusion is a V-shaped spring piece on the first connector, and the highest point of the spring piece abuts against or engages with the module bottom shell in the second groove to form a limiting effect, preventing the first connector from moving arbitrarily.

[0115] In one optional embodiment, the number of second grooves is at least two, and the two second grooves are spaced apart at the bottom of the module bottom shell to limit the position of the first connector in the connected state and the non-connected state, that is, the position of the first connector inside the module bottom shell and the position of the first connector extending out of the module bottom shell and connecting with another module bottom shell.
