To expand the product's applicability, the requirements for the display cabinet frames are becoming increasingly stringent. Compared to traditional flat cabinet frames, more and more adjustable-curvature cabinet frames are being developed. However, once the cabinet frame is adjusted to a preset angle, it is difficult to maintain its stability, making it susceptible to wobbling under external forces. Excessive wobbling may cause changes in the curvature of the cabinet frame, thus affecting the normal display of the screen. Summary of the Invention

The limiting seat is disposed on the second frame and spaced apart from the adjustment rod. One end of the limiting rod is disposed on the mounting base, and the other end of the limiting rod is movable in the limiting seat, for limiting the first frame to a zero-degree position and a maximum rotation angle position relative to the second frame.

[0006] In the adjustment mechanism of one embodiment of the present invention, the limiting rod is provided with a mating part, and the limiting seat is provided with an abutting part. The abutting part can cooperate with the mating part when the limiting rod is in the zero-degree position to ensure the flatness of the display screen in the zero-degree position.

[0007] In the adjustment mechanism of one embodiment of the present invention, the limiting seat is provided with a movable groove, the abutting part is provided on the side walls on opposite sides of the movable groove, and the limiting rod is provided with a mating part that cooperates with the abutting part on opposite side surfaces.

[0008] In the adjustment mechanism of one embodiment of the present invention, the movable groove is provided with toothed structures symmetrically arranged above and below the opening of the first frame, and the abutting part is provided at the top of the tooth of the toothed structure; and / or, the end of the limiting rod facing the first frame is an arc-shaped structure, and the diameter of the arc-shaped structure is adapted to the closest distance between the two movable grooves.

[0010] In one embodiment of the adjustment mechanism of this utility model, the adjustment mechanism further includes a housing handle, one end of which is connected to the mounting base, and the other end of which is fixed to the first frame.

[0011] In one embodiment of the adjustment mechanism of this utility model, the adjustment structure further includes an unlocking component, which is disposed on the mounting base and is used to lock or unlock the length of the adjustment rod extending out of the mounting base to control the included angle between the first frame and the second frame.

[0012] In an embodiment of the adjustment mechanism of this utility model, the adjustment rod includes a connecting rod and a rack structure. The two ends of the connecting rod are respectively connected to the mounting base and the second frame. The rack structure is disposed on the connecting rod to limit the extension length of the adjustment rod.

[0013] According to a second aspect of the present invention, the present invention also provides a display screen, including a display module, a cabinet frame, and a control box. The cabinet frame includes a first frame, a second frame, and the aforementioned adjustment mechanism. The first frame is mounted on both sides of the second frame via the adjustment mechanism.

[0014] The technical solution provided in this application embodiment can include the following beneficial effects: This application designs an adjustment mechanism and a display screen. The adjustment mechanism includes a holding structure and an adjustment structure for adjusting the curvature of the display screen. The adjustment structure is connected between a first frame and a second frame. The holding structure is used to hold the first frame when it rotates relative to the second frame to a preset angle, effectively preventing frame loosening and rebound caused by external force or its own weight, ensuring the stability and consistency of the displayed image. Not only can the adjustment structure achieve multiple curvature adjustments of the display screen to adapt to different installation scenarios and visual needs, improving the product's versatility, but it also solves the inherent stability problem of adjustable screens, avoiding curvature changes due to shaking during use, thereby ensuring high-quality image display.

The adjustment structure includes an adjustment rod and a mounting base. The mounting base is mounted on the first frame, one end of the adjustment rod is movably mounted on the mounting base, and the other end of the adjustment rod is rotatably connected to the second frame. The holding structure is disposed on at least one of the mounting base and the second frame. When the operator applies force, the adjusting rod rotates around the rotation point of the second frame, and the adjusting rod is movably mounted on one end of the mounting base, allowing it to move in the preset direction of the mounting base. This forces the first and second frames to rotate relative to each other, thereby changing the angle between them and ultimately adjusting the curvature of the entire display screen. Once the curvature is adjusted to the correct position, the operating retaining structure prevents the first and second frames from moving or rotating relative to each other, thus firmly maintaining the preset angle and preventing the display screen from shaking or deforming.

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.

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.

[0021] 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.

[0022] like Figures 1 to 6 As shown, this application provides a display screen, including a display module 20, a cabinet frame 10, and a control box. The display module 20 is mounted on the cabinet frame 10, and the control box 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 realizing the transmission of power and signals, such as power supply or other data transmission.

[0023] In one optional embodiment, the control box includes a housing, a battery assembly, a communication module, and a control card. The housing has a cavity, and the communication module and control card are disposed within the cavity. The battery assembly is connected to the housing and enclosed within the cavity. A mounting groove is formed on the housing frame 10, and the housing is mounted in the mounting groove.

[0024] In one 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 2020 according to the processing result.

[0025] In one alternative implementation, such as Figures 1 to 11 As 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 retaining structure 132 and an adjustment structure 131 for adjusting the curvature of the display screen. The adjustment structure 131 is connected between the first frame 11 and the second frame 12. The retaining structure 132 is used to hold the first frame 11 relative to the second frame 12 when it rotates to a preset angle, effectively preventing the cabinet frame 10 from loosening and rebounding due to external forces or its own weight, ensuring the stability and consistency of the displayed image. The adjustment structure 131 not only allows for various curvature adjustments of the display screen to adapt to different installation scenarios and visual needs, improving the product's versatility, but also solves the inherent stability problem of adjustable screens, avoiding curvature changes due to shaking during use, thus ensuring high-quality image display. Furthermore, the retaining structure 132 can reduce component wear or connection fatigue caused by the shaking of the cabinet frame 10, thereby extending the service life of the cabinet frame 10.

[0026] It should be noted that the preset angle refers to any unfolding angle between the minimum rotation angle position and the maximum rotation angle position of the first frame 11 relative to the second frame 12, and this application does not impose any limitation on it.

[0027] In one optional embodiment, there are two first frames 11, which are connected to the two sides of the second frame 12 by an adjustment mechanism 13. The control box is located 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 to adapt to the angle adjustment of 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 straight screen. It is easy and quick to operate and can be applied to different application scenarios.

[0028] In one alternative implementation, such as Figures 10 to 17As shown, the adjustment structure 131 includes an adjustment rod 1312 and a mounting base 1311. The mounting base 1311 is mounted on the first frame 11 of the display screen. One end of the adjustment rod 1312 is movably connected to the mounting base 1311, and the other end of the adjustment rod 1312 extends out of the mounting base 1311 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 1312, 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 or 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 or straight screen. The operation is simple and quick, and it can be applied to different application scenarios.

[0029] For example, after 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 by adjusting the structure 131. This allows the display module 20 mounted on the cabinet frame 10 to cooperate with the cabinet frame 10 to form a corresponding curved 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 to cooperate with the cabinet frame 10 to form a corresponding curved or straight screen. When the display screen is adjusted to the preset angle, the retaining structure 132 will lock this state to prevent accidental shape changes due to gravity, vibration or other external forces during use, thereby achieving a firm hold on the preset angle and avoiding shaking and deformation.

[0030] 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 structure 131, the display screen after the cabinet frame 10 and the display module 20 are assembled can form a corresponding curved screen or straight screen, and the shape of the curved screen can be adjusted according to the shape of the display module 20 through the adjustment structure 131, which is simple and quick to operate. At the same time, this application also uses the retaining structure 132 to prevent the first frame 11 from moving or rotating relative to the second frame 12, thereby achieving the firm maintenance of the first frame 11 relative to the second frame 12 at a preset angle position, effectively resisting external impact and vibration, and avoiding shaking and deformation. Since the cabinet frame 10 and the display module 20 can be adjusted to fit the shape of the display module 20 after assembly by the adjustment structure 131, the individual display unit presents a curved structure. Then, multiple curved display units are spliced ​​together to form a large display with a true curved shape. At the same time, the adjustment angle of the adjustment structure 131 is flexible and arbitrary, so that any irregular shape such as S-shape or C-shape can be formed into a large screen display. Then, combined with the holding structure 132, the adjusted display can be firmly locked to avoid the curvature change caused by shaking during use, thereby ensuring high-quality image display and applicable to different application scenarios.

[0031] In an optional embodiment, a first mounting portion 111 is provided on the first frame 11, and a second mounting portion 121 is provided on the second frame 12. A mounting base 1311 and at least a partially retaining structure 132 are mounted on the first mounting portion 111, and an adjusting rod 1312 and at least a partially retaining structure 132 are connected to the second mounting portion 121. The first mounting portion 111 can be a rib structure on the first frame 11, connected to opposite sides of the first frame 11. It not only strengthens the first frame 11 but also secures the first mounting portion 111, allowing the first frame 11 to be connected to the second frame 12. Similarly, the second mounting portion 121 can be a boss structure on the second frame 12, which can be fixed to the first frame 11 by welding or integral molding. In this embodiment, the adjusting rod 1312 is rotatably connected to the shaft hole of the second mounting portion 121 via a connecting pin. At least a portion of the retaining structure 132 is mounted on the side of the second mounting portion 121 near the display module 20, and the other portion of the retaining structure 132 is fixed on the mounting base 1311. The mounting base 1311 is mounted on the first mounting portion 111, and at least a portion of the retaining structure 132 is movably connected to the other portion of the retaining structure 132. The end of the adjusting rod 1312 away from the second mounting portion 121 is telescopically mounted in the mounting base 1311 so that it can be adjusted when the length of the adjusting rod 1312 is extended or shortened. The first frame 11 is rotated 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 cabinet frame 10 structure, so that the dynamic deformation of the cabinet frame 10 can be realized through the mechanical adjustment structure 131. Combined with the two-part holding structure 132, a self-locking mechanical structure is added to the curvature adjustment of the display screen. This solves the problem that the curved screen is easy to shake and deform after adjustment in the prior art, which affects the display effect. It has significant application value in the fields of large LED display screens, deformable billboards and the like.

[0032] In an optional embodiment, the retaining structure includes a limiting rod 1322 and a limiting seat 1321. The limiting seat 1321 is disposed on the second frame 12. One end of the limiting rod 1322 is connected to the adjusting structure 131 located on the first frame 11, and the other end of the limiting rod 1322 is movable in the limiting seat 1321. This is used to restrict the first frame 11 to the zero-degree position and the maximum rotation angle position relative to the second frame 12. When the first frame 11 and the second frame 12 are rotated to the fully flattened or maximum angle, the limiting rod 1322 can prevent the first frame 11 from continuing to rotate forward relative to the second frame 12. It can not only provide friction or locking force at the zero-degree position and the maximum rotation angle position, but also better ensure the flatness or curvature of the first frame 11 and the second frame 12 when rotated to these two angles. It can also prevent damage to the structural components of the display screen due to excessive angle. This ensures both the flexibility of use and the safety and reliability of operation, making this display screen very suitable for application scenarios that require repeated changes in curvature and complex on-site installation environments.

[0033] In an optional embodiment, the limiting rod 1322 is provided with a mating part 13221, and the limiting seat 1321 is provided with an abutment part 13211. The abutment part 13211 can engage with the mating part 13221 when the limiting rod 1322 is in the zero-degree position to ensure the flatness of the display screen in the zero-degree position, so as to meet the professional display requirements. This provides a unique and precise mechanical position for the display screen in the zero-degree position, ensuring that it is in the same position every time it returns to the zero-degree position. At the same time, the engagement of the abutment part 13211 and the mating part 13221 can greatly enhance the rigidity of the connection point of the display screen in the zero-degree position, resist the torsion of the display screen itself or external forces, avoid deformation, and eliminate the play that may exist in the simple limiting method, so that the first frame 11 and the second frame 12 work like a solid integral box frame 10.

[0034] It should be noted that traditional limiting methods may have slight wobble or gaps. For a display screen, even a small gap at the connection between the two cabinet frames 10 can compromise the overall flatness of the screen. Especially when displaying solid color images, shadows or bright lines may be visible at the splicing point, severely affecting the visual experience. Therefore, this application, through the cooperation of the abutment part 13211 and the mating part 13221, not only provides a unique and precise mechanical position when the first frame 11 rotates relative to the second frame 12 to the zero-degree position, ensuring that it is in the same position every time it returns to the zero-degree position, but also greatly enhances the rigidity of the connection point at the zero-degree position, resisting the screen's own torque or external forces and preventing deformation.

[0035] For example, when the operator rotates the first frame 11 relative to the second frame 12 to a nearly fully flattened position, the abutment portion 13211 will precisely embed or fit into the mating portion 13221, thereby effectively eliminating manufacturing tolerances and assembly gaps between all moving parts. The abutment portion 13211 can be a specific structure machined on the limiting rod 1322, such as a groove, a plane, a protrusion, or a precisely machined shaft segment. The abutment portion 13211 can also be a complementary specific structure machined on the limiting seat 1321, which can also be a protrusion, a plane, or a slot, to achieve precise positioning of the first frame 11 relative to the second frame 12 at the zero-degree position through surface contact or interference fit, rather than simple point contact or line contact.

[0036] In an optional embodiment, the limiting seat 1321 is provided with a movable groove 13212, and the abutment part 13211 is provided on the side walls of opposite sides of the movable groove 13212. The limiting rod 1322 is provided with a mating part 13221 on opposite sides that cooperates with the abutment part 13211. Over-positioning is achieved by contacting or constraining each other on both sides at the same time, eliminating the possible small gaps in the freedom of the display screen in the length, width and / or height directions of the limiting rod 1322. This is much more stable and precise than simply providing a mating part 13221 on one side. It also ensures that there is no looseness between the first frame 11 and the second frame 12 at the zero-degree position, and they are as solid as a whole, thus providing the most basic mechanical guarantee for the excellent flatness of the display screen.

[0037] In an optional embodiment, the movable groove 13212 is symmetrically provided with toothed structures 13213 facing the opening of the first frame 11. An abutment portion 13211 is located at the top of the teeth of the toothed structure 13213. When the user adjusts the screen curvature, the limiting rod 1322 slides within the movable groove 13212. When the mating portion 13221 of the limiting rod 1322 slides to the position of the toothed structure 13213, the abutment portion 13211 engages with the mating portion 13221, allowing the user to feel a clear click or change in resistance, indicating that the first frame 11 has rotated relative to the second frame 12 to a nearly completely flattened position, thus stabilizing at zero degrees. Placing the abutment portion 13211 at the top of the teeth of the toothed structure 13213 ensures the precise position of the abutment portion 13211 within the movable groove 13212 and reduces the frictional force when the limiting rod 1322 slides relative to the limiting seat 1321, allowing the user to smoothly switch between different curvatures.

[0038] In an optional embodiment, the end of the limiting rod 1322 facing the first frame 11 is an arc-shaped structure 13222. The diameter of the arc-shaped structure 13222 is adapted to the closest distance between the two movable slots 13212, that is, the minimum distance between the tops of the two teeth. This allows the limiting rod 1322 to be restricted between the two movable slots 13212, preventing the limiting rod 1322 from having no movement or wobbling in the vertical direction when it is in the zero-degree position. This further eliminates the small gaps in all directions when the first frame 11 is rotated relative to the second frame 12 to a position that is almost completely flattened, ensuring the repeatability and reliability of the positioning.

[0039] In an optional embodiment, the abutment portion 13211 includes a ball-head plunger disposed on the limiting seat 1321, and the mating portion 13221 includes a groove disposed on the limiting rod 1322. The shape of the ball head of the ball-head plunger is adapted to the shape of the groove. When the groove on the limiting rod 1322 moves to a position that is exactly aligned with the ball-head plunger, the ball head of the ball-head plunger clicks into the groove under the action of spring force. At this time, an additional force needs to be applied to push the ball head out of the groove, so that the limiting rod 1322 can continue to move. In this application, a toothed structure 13213 and a ball-head plunger are provided on the limiting seat 1321 to engage with a groove on the arc-shaped structure 13222 to ensure the flatness of the first frame 11 when it is rotated relative to the second frame 12 to a position that is almost completely flattened, while providing positioning and tactile feedback from zero degrees.

[0040] In an optional embodiment, the limiting rod 1322 includes a connecting section 1322a and a limiting section 1322b. The connecting section 1322a is mounted on the mounting base 1311, and the limiting section 1322b extends from one end of the connecting section 1322a toward one side of the limiting base 1321. An arcuate structure 13222 is formed on the side of the limiting section 1322b away from the connecting section 1322a, and grooves are provided on the upper and lower sides of the arcuate structure 13222.

[0041] In an optional embodiment, the adjustment mechanism 13 further includes a housing handle 133, one end of which is connected to the mounting base 1311, and the other end of which is fixed to the first frame 11. When the display screen is being adjusted or installed, the operator can hold the housing handle 133 to adjust the rotation angle of the first frame 11 relative to the second frame 12, so that the adjustment rod 1312 can be adjusted to a 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 1312 is fixed, the operator can hold the housing handle 133 to install or move the display screen to support the weight of the display screen and improve efficiency.

[0042] 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 adjustment rod 1312 extending out of the box handle 133 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 adjustment rod 1312 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.

[0043] In one optional embodiment, the case handle 133 includes a grip portion 1331, both ends of which are fixed to the rib structure. A mounting base 1311 is rotatably mounted on one end of the grip portion 1331. The case handle 133 also includes a connecting base 1332. One end of the mounting base 1311 is rotatably connected to the grip portion 1331, and the other end is rotatably connected to the connecting base 1332. The connecting base 1332 is fixed to the rib structure, allowing the adjusting rod 1312 to be rotatably connected to the mounting base 1311, the connecting base 1332, and the grip portion 1331. This allows the adjusting rod 1312 to rotate relative to the second connecting base 1332 via the mounting base 1311 when adjusting the length of the rod extending out of the case handle 133.

[0044] In an alternative embodiment, the housing handle 133 includes a gasket mounted on the pivot of the connector 1332 and located between the connector 1332 and the mounting base 1311.

[0045] In an optional embodiment, the mounting base 1311 includes a first base body 13111 and a second base body 13112. The first base body 13111 and the second base body 13112 are interlocked to form a movable groove 13212. An adjusting rod 1312 is slidably installed in the movable groove 13212 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 1312 extending out of the movable groove 13212. This allows the display screen to form a corresponding curved screen or a straight screen, making the operation simple and quick. It solves the problem of the display screen having a relatively limited range of uses, meets the splicing requirements of conventional screens and irregularly shaped screens, and enables the display screen to be applied to different application scenarios.

[0046] In an optional embodiment, the adjustment mechanism 13 further includes an unlocking component 1314, which is disposed on the mounting base 1311 and is used to lock or unlock the length of the adjustment rod 1312 extending out of the mounting base 1311 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 housing frame 10. After unlocking, the connection length of the adjustment rod 1312 can be changed by pushing or pulling the housing handle 133 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.

[0047] 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 1314 is operated to unlock the adjusting rod 1312 from the mounting base 1311. Then, the length of the adjusting rod 1312 extending from the mounting base 1311 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 unlocking component 1314 locks the adjusting rod 1312 from the mounting base 1311 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.

[0048] In an optional embodiment, the unlocking component 1314 includes a button 13141 and a limiting block 13142. The limiting block 13142 is provided with adjusting teeth, which are used to engage or disengage with the rack structure 13122 on the adjusting rod 1312 to achieve precise locking and immediate release of the length of the adjusting rod 1312.

[0049] In an optional embodiment, the mounting base 1311 is provided with a limiting block 13142 groove, the limiting block 13142 being movably installed in the limiting block 13142 groove. A button 13141 is connected to the limiting block 13142 and is used to drive the adjusting gear to engage or disengage from the rack structure 13122. Both the limiting block 13142 groove and the limiting block 13142 are square in shape to restrict the limiting block 13142 from rotating relative to the mounting base 1311 during the pressing process via the button 13141, thus providing a limiting function.

[0050] In an optional embodiment, the unlocking component 1314 further includes an elastic element 13143, which always maintains an elastic force in the direction of the limiting block 13142 to drive the adjusting teeth to abut against the rack structure 13122. This ensures the locking accuracy of the unlocking component 1314 while also taking into account the ease of operation, thereby improving the automatic reset capability and operational reliability of the unlocking component 1314.

[0051] In an optional embodiment, the adjusting rod 1312 includes a connecting rod 13121 and a rack structure 13122. The two ends of the connecting rod 13121 are connected to the mounting base 1311 and the second frame 12, respectively. The rack structure 13122 is disposed on the connecting rod 13121 to limit the extension length of the adjusting rod 1312. While ensuring mechanical reliability, it can not only provide millimeter-level length adjustment accuracy, but also make the connecting rod 13121 and the rack structure 13122 made of different materials, realizing a structural configuration of rigidity and flexibility of the adjusting rod 1312. For example, the connecting rod 13121 is made of aluminum alloy or plastic material, and the rack structure 13122 is made of stainless steel material.

[0052] For example, the connecting rod 13121 is provided with a first groove along its length, and the rack structure 13122 is detachably installed in the first groove, which improves the maintainability, modularity and environmental adaptability of the adjustment mechanism 13, and significantly reduces maintenance costs and downtime while ensuring mechanical performance.

[0053] In an optional embodiment, the connecting rod 13121 is provided with a limiting groove 13124, and a limiting post is installed in the mounting base 1311. The limiting post cooperates with the limiting groove 13124 to limit the sliding distance of the connecting rod 13121 relative to the mounting base 1311. This allows for precise control of the sliding stroke of the connecting rod 13121 through a mechanical hard limiting structure, preventing the connecting rod 13121 from separating from the mounting base 1311 and ensuring the reliability and safety of the adjustment structure 131.

[0054] In an optional embodiment, the adjustment structure 131 includes a damping element disposed on the mounting base 1311 for cooperating with the rack structure 13122 to achieve precise control of the movement resistance of the adjustment rod 1312, so as to add a 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.

[0055] In an optional embodiment, the mounting base 1311 includes a friction block 1315. The mounting base 1311 has a receiving groove, in which the friction block 1315 is installed and abuts against the end face of the connecting rod 13121. This prevents breakage due to prolonged contact with the rack structure 13122. Wear indicators can also be provided on the friction block 1315 for easy replacement. The receiving groove can be a pull-out design, allowing replacement of the friction block 1315 without disassembling the connecting rod 13121. Furthermore, the friction block 1315 can also be spring-loaded to push it towards one side of the rack structure 131221, allowing the spring structure to increase the clamping force applied to the rack structure 13122 as wear increases.

[0056] In an optional embodiment, the friction block 1315 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 13122, so that the sliding of the connecting rod 13121 is smoother and has movement feedback.

[0057] In an optional embodiment, the adjusting rod 1312 further includes a cylindrical strip 13123 made of wear-resistant material. The connecting rod 13121 has grooves on both sides, and at least a portion of the cylindrical strip 13123 is accommodated in the grooves for sliding connection with both sides of the mounting base 1311. This ensures the stability of the adjusting rod 1312 during adjustment, preventing any unevenness or jamming. This not only improves the mechanical durability and smoothness of the adjusting rod 1312 but also greatly enhances the ease of operation. The overall structure is simple and very convenient to operate.

[0058] In an optional embodiment, a pin is also provided in the mounting base 1311. The pin has an arc groove that matches the cylindrical strip 13123. A portion of the cylindrical strip 13123 is slidably connected in the arc groove. This not only assists in the movement and guidance of the adjusting rod 1312, but also reduces the friction between the cylindrical strip 13123 and the mounting base 1311, thereby achieving precise guidance of the movement trajectory of the adjusting rod 1312 and optimized load distribution.

[0059] In an optional embodiment, the mounting base 1311 further includes a bearing 1313, which is rotatably mounted in the seat of the mounting base 1311 and contacts the two end faces opposite to the connecting rod 13121. This allows the adjusting rod 1312 to slide more smoothly relative to the mounting base 1311 when adjusting the curvature between the first frame 11 and the second frame 12. While maintaining adjustment accuracy, this also ensures the service life of the adjusting rod 1312, achieving multi-dimensional mechanical optimization of the adjustment structure 131.

[0060] In an optional embodiment, a connecting shaft connects the first seat 13111 and the second seat 13112, and the bearing 1313 is rotatably mounted on the connecting shaft. This allows for a reduction in the manufacturing cost of the mounting seat 1311 through its split design. Alternatively, a through-type connecting shaft can be used to connect the first seat 13111 and the second seat 13112 together and install the bearing 1313 in the connecting shaft to facilitate the use of the adjusting rod 1312, making the sliding of the adjusting rod 1312 relative to the mounting seat 1311 smoother.

[0061] In an optional embodiment, the adjustment structure 131 includes a feedback element, the front of the connecting rod 13121 is provided with a scale, and the back of the connecting rod 13121 is provided with a feedback hole corresponding to the scale. The feedback element and the feedback hole cooperate to form a signal indicator so as to provide a positioning reminder function.

[0062] For example, the distance between two adjacent feedback holes corresponds to five scale values ​​on the scale, so that when the length of the adjusting rod 1312 is adjusted, the feedback element can cooperate with each feedback hole on the adjusting rod 1312 to provide a positioning reminder function, preventing the adjusting rod 1312 from being too long or too short when adjusting the length, thereby better controlling the length of the adjusting rod 1312 extending out of the movable slot 13212.

[0063] In an alternative embodiment, the feedback element includes a plunger or a glass ball, and the mounting base 1311 is provided with a plunger groove in which the plunger or glass ball is installed.

[0064] In one alternative implementation, such as Figures 1 to 5 , Figures 18 to 20 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 structure 131.

[0065] For example, the first frame 11 has a first end at both ends, and the second frame 12 has a second end at both ends. The two first ends are rotatably connected to the two second ends via a connecting structure 14. A first mounting part 111 is disposed between the two first ends, and a second mounting part 121 is disposed between the two second ends. A mounting base 1311 and a cabinet handle 133 are installed in the first mounting part 111. An adjusting rod 1312 is rotatably mounted on the second mounting part 121 at one end away from the first mounting part 111. This allows the adjusting structure 131 to adjust the angle 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 curved or straight screen. In other words, 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 to cooperate with the cabinet frame 10 to form a curved or straight screen. This operation is simple and quick, and can be applied to different application scenarios.

[0066] Specifically, when the cabinet frame 10 needs to adjust the angle between the first frame 11 and the second frame 12, the unlocking component 1314 is operated to unlock the adjusting rod 1312 from the mounting base 1311. Then, the length of the adjusting rod 1312 extending from the mounting base 1311 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 adjusting rod 1312 is locked to the mounting base 1311 through the unlocking component 1314 to prevent the first frame 11 from rotating freely relative to the second frame 12. At the same time, this application can also keep the display screen horizontal when it is in a zero-degree position through the holding structure. The operation is simple and quick and can be applied to different application scenarios.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] In an optional embodiment, the housing frame 10 further includes a protective structure 15, which includes a protective plate 152, a reset member 153, and a fixing seat 151 mounted on the first frame 11. The fixing seat 151 is provided with an inclined guide groove 1512. The protective plate 152 has a connecting shaft 154, which is slidably mounted in the guide groove 1512. The two ends of the reset member 153 abut against the fixing seat 151 and the protective plate 152 respectively, and are used to maintain an elastic force in the direction away from the fixing seat 151, so as to drive the protective plate 152 to move away from the fixing seat 151, 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.

[0073] For example, the first frame 11 is provided with a fixing groove and a clearance groove, and the fixing seat 151 is fixed in the fixing column in the fixing groove. The protective plate 152 is provided with a connecting boss 1522 and a guide boss 1521, and the outer wall of the second frame 12 is provided with a clearance groove. The connecting shaft 154 passes through the connecting boss 1522 and connects to the guide groove 1512. The guide boss 1521 is used to cooperate with the clearance groove so that the protective plate 152 can move away from the display module 20 when subjected to compressive force, so that the two frame structures can be well spliced ​​together.

[0074] In an optional embodiment, the mounting base 151 is provided with a guide ramp 1513 and a ramp groove 1511. One end of the reset member 153 is installed in the ramp 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 plate 152 to move away from the mounting base 151. The inclination angle of the guide ramp 1513 is the same as the inclination angle of the ramp groove 1511 and the guide groove 1512, so that the mounting base 151 can be installed obliquely in the mounting groove along the guide ramp 1513 to ensure the parallelism between the protective plate 152 and the outer wall of the first frame 11. At the same time, it also allows the protective plate 152 to move along the guide direction of the guide groove 1512 via the guide boss 1521 and retract into the clearance groove.

[0075] For example, the first frame has opposite first and second corners, and the protective structure 15 is installed on it. When the two box frames are spliced, the protective plate 152 moves toward the opposite direction of the two box frames and applies external force to each other, so that the protective plate 152 can retract into the first frame, so that the two box frames can be spliced ​​together well.

[0076] In an alternative embodiment, the housing frame 10 further includes a first positioning post disposed on one side of the protective structure 15 to restrict the movement of the protective plate 152.

[0077] For example, the housing frame 10 is provided with a movable hole communicating with the fixing groove. The first positioning post has an abutting end and a limiting end. The limiting end is used to cooperate with the protective sheet 152 to restrict the protective sheet 152 from moving away from the display module 20 and prevent the protective sheet 152 from retracting. The abutting end is used to drive the limiting end to release the limiting of the protective sheet 152 when the two housing frames 10 are spliced.

[0078] In an optional embodiment, the display module 20 includes a module base shell 21 and a lamp plate 22 with LED beads. Both the module base shell 21 and the lamp plate 22 are flexible structures that can be bent. The lamp plate 22 is disposed on the module base shell 21 so that the display module 20 can form an arc-shaped display screen that cooperates with the cabinet frame 10.

[0079] In an optional embodiment, the module base shell 21 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 plate 22 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.

[0080] In an optional embodiment, the module base shell 21 includes a plurality of shells arranged sequentially along a first direction, and at least one limiting component 23 is connected between two adjacent shells. The limiting component 23 is used to limit the deformation of the module base shell 21 when it undergoes bending deformation, so as to prevent the display module 20 from being damaged due to excessive deformation of the module base shell 21 and ensure that the display module 20 can be used normally.

[0081] For example, the housing includes a first housing 21a and a second housing 21b. One part of the structure of the limiting component 23 is formed on the first housing 21a, and the other part of the structure of the limiting component 23 is formed on the second housing 21b. 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 23 can form a limit to restrict the relative displacement between the first housing 21a and the second housing 21b, so that the bottom shell 21 of the module will no longer undergo more deformation, avoid damage to the display module 20 due to excessive deformation of the bottom shell 21 of the module, and ensure that the display module 20 can be used normally.

[0082] 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 23 can form a limit to restrict the relative displacement between the first housing 21a and the second housing 21b, so that the bottom shell 21 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 21 of the module, and ensuring that the display module 20 can be used normally.

[0083] After adopting the above technical solution, due to the high flexibility of the module base shell 21, 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 21 during bending deformation by limiting component 23, thereby avoiding the risk of damage to the display module 20 due to excessive bending deformation of the module base shell 21 during transportation or assembly, and ensuring that the display module 20 can be used normally.

[0084] In an optional embodiment, the limiting component 23 includes a first limiting part 231 and a second limiting part 232. The first limiting part 231 is formed on one of the two adjacent housings, and the second limiting part 232 is formed on the other of the two adjacent housings. The first limiting part 231 and the second limiting part 232 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 housing 21, and to ensure that the display module 20 can be used normally.

[0085] In an optional embodiment, the first limiting part 231 has a first abutting part 13211, and the second limiting part 232 has a second abutting part 13211. When the module bottom shell 21 undergoes bending deformation, the first abutting part 13211 abuts against the second abutting part 13211 or the end opposite to the second abutting part 13211, so that the module bottom shell 21 no longer undergoes further deformation. This can prevent the display module 20 from being damaged due to excessive deformation of the module bottom shell 21, and ensure that the display module 20 can be used normally.

[0086] For example, when the display surface of the display module 20 is concave and the deformation reaches its maximum, the first abutting part 13211 abuts against the second abutting part 13211 to form a limit, which is used to limit the relative displacement between the first housing 21a and the second housing 21b, so that the bottom shell 21 of the module will no longer undergo more deformation, avoid damage to the display module 20 due to excessive deformation of the bottom shell 21 of the module, and ensure that the display module 20 can be used normally.

[0087] Alternatively, when the display surface of the display module 20 bulges outward and the deformation reaches its maximum, the opposite ends of the first abutting part 13211 and the second abutting part 13211 abut against each other, that is, the first abutting part 13211 abuts against the side wall of the second housing 21b; the opposite ends of the second abutting part 13211 and the first abutting part 13211 abut against each other, that is, the second abutting part 13211 abuts against the side wall of the first housing 21a, which is used to limit the relative displacement between the first housing 21a and the second housing 21b, so that the bottom shell 21 of the module will no longer undergo more deformation, avoid damage to the display module 20 due to excessive deformation of the bottom shell 21 of the module, and ensure that the display module 20 can be used normally.

[0088] In an optional embodiment, the first limiting part 231 has a first connecting part, and the second limiting part 232 has a second connecting part. The first abutting part 13211 is connected to the housing through the first connecting part and forms a first limiting groove 13124. The second abutting part 13211 is connected to the housing through the second connecting part and forms a second limiting groove 13124. The first abutting part 13211 moves in the second limiting groove 13124, and the second abutting part 13211 moves in the first limiting groove 13124. When the deformation of the display module 20 reaches its maximum, the first abutting part 13211 can form a limit with the two opposite end faces of the first limiting groove 13124, and the second abutting part 13211 can form a limit with the two opposite end faces of the second limiting groove 13124, so that the bottom shell 21 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 21 and ensuring that the display module 20 can be used normally.

[0089] In one optional embodiment, the first abutting portion 13211 is perpendicularly connected to the first connecting portion, that is, the first abutting portion 13211 and the first connecting portion form an L-shaped structure.

[0090] In one optional embodiment, the second abutting portion 13211 is perpendicularly connected to the second connecting portion, that is, the second abutting portion 13211 and the second connecting portion form an L-shaped structure.

[0091] It should be noted that the first limiting part 231 and the second limiting part 232 can also be constructed in other ways. Their main purpose is to limit the relative displacement between the first housing 21a and the second housing 21b. This application does not impose any restrictions on them.

[0092] In an optional embodiment, the display module 20 further includes a first connector and a second connector. The lamp board 22 is connected to the module bottom shell 21 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 21 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 screen.

[0093] 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.

[0094] 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 2020, so as to achieve seamless splicing of the two adjacent display modules 2020. This solves the long-standing problem of bright and dark lines at the splicing point of the two adjacent display modules 2020 while ensuring high-definition display of the picture.

[0095] In an optional embodiment, the second connector includes a positioning copper post with a protruding surface connected to the back side of the lamp panel 22, and the end of the positioning copper post away from the protruding surface connected to the module bottom shell 21. The back side of the lamp panel 22 refers to the side of the lamp panel 22 facing the module bottom shell 21.

[0096] In an alternative embodiment, the side of the module base 21 is provided with an opening structure for the connector to pass through and to mate with a second connector on another module base 21.

[0097] In one optional embodiment, the first connector is provided with a first limiting member, and the module bottom shell 21 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 21.

[0098] In one optional embodiment, the first limiting member is a first groove provided on the side of the first connector, and the second limiting member is a protrusion provided on the module bottom shell 21. The first groove and the protrusion cooperate to limit the movement of the first connector relative to the module bottom shell 21. The module bottom shell 21 and the first connector have left and right cooperation positions with limiting strips, and the protrusion is provided on the limiting strips.

[0099] 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 21 and the position of the first connector extending out of the module bottom shell 21 and connecting with another module bottom shell 21.

[0100] In an optional embodiment, the first limiting member is an elastic protrusion provided on the first connector, and the second limiting member is a second groove provided on the module bottom shell 21. The elastic protrusion cooperates with the second groove to limit the movement of the first connector relative to the module bottom shell 21. Specifically, 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 21 in the second groove to form a limiting position, preventing the first connector from moving arbitrarily.

[0101] 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 21 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 21 and the position of the first connector extending out of the module bottom shell 21 and connecting with another module bottom shell 21.
