Description

Technical Field

[0001] This invention relates to the field of display technology, and in particular to an adjustable bending display screen. Background Technology

[0002] To achieve the bending adjustment function of outdoor advertising displays, adjustable bending structures adapted to this field have appeared on the market. Their core is to drive the deformation of the display panel through the cooperation of the bending base and the adjustment component. However, the solution has a uniform and obvious limitation, namely, it can only achieve bending adjustment in a single direction.

[0003] In the field of outdoor advertising, users' needs for the direction of curvature often change dynamically with the installation scenario: outdoor advertising screens may need to bend horizontally to adapt to the curved structure of the building facade, or they may need to bend vertically to fit the curved surface of columnar carriers such as bus stops and street light poles; some temporary outdoor advertising spaces also need to switch the direction of curvature according to the outline of the site space to maximize the display effect.

[0004] While the existing single-direction adjustment structure can meet the switching requirement by splicing individual display screens in different directions, this operation is quite cumbersome. It requires dismantling the previously adjusted display screen splicing structure and then reassembling it along the target direction, making the process complicated, time-consuming, and labor-intensive. Summary of the Invention

[0005] The main objective of this invention is to provide an adjustable bending display screen, which aims to enable the adjustable temperature display screen to bend in different directions.

[0006] To achieve the above objectives, the present invention provides an adjustable bending display screen, comprising:

[0007] The display panel is flexible;

[0008] The bendable display panel is fixed to one side of the bendable base. The bendable base includes multiple sub-bases, at least two of which are arranged laterally and at least two of which are arranged longitudinally. Adjacent sub-bases are rotatably connected. The side of the multiple sub-bases facing away from the display panel is provided with a guide rail section, and the multiple guide rail sections constitute a rotating guide rail.

[0009] An adjustment component is slidably connected to the bending base via the rotating guide rail and is rotatable between the horizontal and vertical directions to adjust the rotation of at least two of the sub-bases arranged along the horizontal or vertical directions, thereby adjusting the curvature of the display panel.

[0010] In one embodiment, each of the sub-bases is provided with a buckle and / or a slot on its periphery, and two adjacent sub-bases are connected and rotatably linked by the buckle and the slot.

[0011] In one embodiment, the bending base includes a longitudinal selection component and a transverse selection component. The longitudinal selection component is used to fix the sub-bases adjacent along the longitudinal direction, and the transverse selection component is used to fix the sub-bases adjacent along the transverse direction. On the same bending base, when the longitudinal selection component is used, the adjustment component rotates on the rotation guide rail to a transverse adjustment position to adjust the rotation angle of the sub-bases arranged along the transverse direction; when the transverse selection component is used, the adjustment component rotates on the rotation guide rail to a longitudinal adjustment position to adjust the rotation angle of the sub-bases arranged along the longitudinal direction.

[0012] In one embodiment, the longitudinal selection component includes a longitudinal connecting hole and a first connecting rod. The longitudinal connecting hole extends through the sub-base along the longitudinal direction. Each sub-base has at least two longitudinal connecting holes, and the first connecting rod passes through at least two longitudinal connecting holes in adjacent sub-bases. The lateral selection component includes a lateral connecting hole and a second connecting rod. The lateral connecting hole extends through the sub-base along the lateral direction. Each sub-base has at least two lateral connecting holes, and the second connecting rod passes through at least two lateral connecting holes in adjacent sub-bases.

[0013] In one embodiment, both the first connecting rod and the second connecting rod include a connecting end and a free end disposed opposite to each other. The connecting end is connected to the outer wall of the bending base. The free end of the first connecting rod passes through the bending base along the coaxial longitudinal connecting hole, and the free end of the second connecting rod passes through the bending base along the coaxial transverse connecting hole.

[0014] In one embodiment, the first connecting rod and the second connecting rod have the same structure.

[0015] In one embodiment, the adjustment assembly includes an arc-shaped fitting assembly and a rotating adjustment rod. The arc-shaped fitting assembly includes a first connector and a second connector. The first ends of the first connector and the second connector are respectively connected to the guide rail segments on different sub-bases. The second ends of the first connector and the second connector are arranged facing each other, and the second ends of the first connector and the second connector are connected through the rotating adjustment rod. Rotating the rotating adjustment rod causes the first connector and the second connector to rotate relative to each other.

[0016] In one embodiment, the first end of the first connector and the second connector is provided with a slider and a fastener. The rotating guide rail includes a guide protrusion protruding from the bending base. The bottom of the slider is provided with a groove that matches the guide protrusion. The fastener passes through the slider and extends into the groove to lock the slider and the guide protrusion.

[0017] In one embodiment, the rotation angle between two adjacent subbases is between 20° and 40°.

[0018] In one embodiment, the gap between adjacent guide rail segments is 2 to 3 millimeters, and the length of the groove is greater than 5 millimeters.

[0019] In one embodiment, the adjustable bendable display screen further includes an edge connector, on which an assembly mechanism is provided. The assembly mechanism fixes the edge connectors on different adjustable bendable display screens to achieve the assembly of multiple adjustable bendable display screens.

[0020] In the technical solution of this invention, the display panel is fixed to a flexible, adjustable base, forming a panel-base linkage deformation structure. This ensures that the bending adjustment of the base is accurately transmitted to the panel, preventing the panel from detaching from the base or experiencing uneven stress. The adjustable base employs a multi-sub-base combination design, ensuring that at least two sub-bases are arranged horizontally and at least two are arranged vertically. Furthermore, the rotational connection between adjacent sub-bases breaks the rigid limitations of traditional single-direction bending structures, giving the base the potential for multi-directional deformation and providing structural support for both horizontal and vertical bending. This sub-base combination design is not a simple splicing but rather achieves flexible linkage through rotational connection. This ensures synchronous movement of adjacent sub-bases during adjustment and prevents damage to the overall structure from deformation of a single base, adapting to the large-area, high-stability requirements of outdoor advertising screens. The guide rails on the side of the sub-base facing away from the display panel are spliced ​​together to form a rotating guide rail. This design provides a dual basis for the adjustment component. On the one hand, the continuity of the guide rail ensures that the adjustment component can slide smoothly along the guide rail, facilitating the adjustment of the working position according to the bending requirements and achieving precise bending adjustment in different areas. On the other hand, the overall structure of the rotating guide rail supports the adjustment component to freely rotate between the horizontal and vertical directions without disassembling or replacing the adjustment component, thus completing the switching of adjustment direction. The sliding connection and steering function between the adjustment component and the rotating guide rail form the core advantage of seamless switching without disassembly and splicing. When horizontal bending is required, the adjustment component can be directly rotated to the corresponding position on the rotating guide rail, driving the horizontally arranged sub-bases to rotate synchronously, causing the display panel to form a horizontally bent shape. When switching to vertical bending is required, it is only necessary to turn the adjustment component to the vertical adjustment position to drive the vertically arranged sub-bases to rotate. In this process, no parts need to be removed, and the original bending shape can be naturally flattened as the adjustment component changes direction, completely avoiding the cumbersome operation of disassembly and splicing in traditional solutions. Furthermore, this structural design ensures the precision of bending adjustment. By adjusting the components to drive the sub-base in a specific direction, interference from multi-directional adjustments is avoided. This allows the curvature of the display panel to be precisely controlled according to the actual needs of outdoor installation scenarios. It can adapt to the gentle curves of building facades as well as the curved contours of columnar carriers, greatly improving the product's scenario adaptability and practicality. This provides reliable technical support for the flexible installation and optimized display effects of outdoor advertising screens.

[0021] In other words, by constructing an integrated structure with multi-sub-base linkage, rotating guide rail guidance, and adjustable component rotation adaptation, the function of flexibly switching between horizontal and vertical bending can be achieved without disassembling the display screen body, simply by adjusting the component rotation. This greatly simplifies the direction switching operation in outdoor scenarios and adapts to diverse installation needs such as curved building facades, columnar carriers, and temporary exhibition venues. At the same time, it provides a stable and precise structural foundation for adjusting the curvature of the display screen, taking into account both the reliability of bending deformation and the stress safety of the display panel, and is suitable for long-term use in complex outdoor environments.

[0038] This invention proposes an adjustable bending display screen.

[0039] Please see Figures 1 to 7 In one embodiment of the present invention, the adjustable bending display screen includes:

[0040] Display panel 100, display panel 100 is flexible;

[0041] The bending base 200 has a bendable display panel 100 fixed to one side. The bending base 200 includes a plurality of sub-bases 210, at least two of which are arranged in a horizontal direction and at least two of which are arranged in a vertical direction. Adjacent sub-bases 210 are rotatably connected. The side of the plurality of sub-bases 210 away from the display panel 100 is provided with a guide rail section 241. The plurality of guide rail sections 241 constitute a rotating guide rail 240.

[0042] The adjustment component 300 is slidably connected to the bending base 200 via a rotating guide rail 240 and is rotatable between the horizontal and vertical directions. It is used to adjust the rotation of at least two sub-bases 210 arranged in the horizontal or vertical direction to adjust the curvature of the display panel 100.

[0043] In the technical solution of this invention, the display panel 100 is fixed to a flexible bending base 200, forming a panel-base linkage deformation structure. This ensures that the bending adjustment of the base is accurately transmitted to the panel, preventing the panel from detaching from the base or experiencing uneven force. The bending base 200 adopts a design combining multiple sub-bases 210, ensuring that at least two sub-bases 210 are arranged horizontally and at least two are arranged vertically. Furthermore, the rotational connection between adjacent sub-bases 210 breaks the rigid limitations of traditional single-direction bending structures, giving the base the potential for multi-directional deformation and providing structural support for both horizontal and vertical bending. This sub-base 210 combination design is not a simple splicing but achieves flexible linkage through rotational connection. It ensures synchronous movement of adjacent sub-bases 210 during adjustment and avoids damage to the overall structure caused by deformation of a single base, adapting to the large-area, high-stability requirements of outdoor advertising screens. The guide rail segment 241 on the side of the sub-base 210 away from the display panel 100 is spliced ​​to form a rotating guide rail 240. This design provides a dual basis for the adjustment component 300. On the one hand, the continuity of the guide rail segment 241 ensures that the adjustment component 300 can slide smoothly along the guide rail, which is convenient to adjust the position of action according to the bending requirements and achieve precise bending adjustment in different areas. On the other hand, the overall structure of the rotating guide rail 240 supports the adjustment component 300 to freely rotate between the horizontal and vertical directions. The adjustment direction can be switched without disassembling or replacing the adjustment component 300. The sliding connection and steering function between the adjustment component 300 and the rotating guide rail 240 form the core advantage of seamless switching without disassembly and assembly. When horizontal bending is required, the adjustment component 300 can be directly rotated to the corresponding position on the rotating guide rail 240, driving the horizontally arranged sub-bases 210 to rotate synchronously, causing the display panel 100 to form a horizontally bent shape. When switching to vertical bending is required, the adjustment component 300 only needs to be turned to the vertical adjustment position to drive the vertically arranged sub-bases 210 to rotate. In this process, no parts need to be removed, and the original bending shape can be naturally flattened as the adjustment component 300 changes direction, completely avoiding the cumbersome operation of disassembly and assembly in traditional solutions. Furthermore, this structural design ensures the precision of bending adjustment. By adjusting the sub-base 210 in a specific direction through the targeted drive of the component 300, interference in multi-directional adjustments is avoided. This allows the curvature of the display panel 100 to be precisely controlled according to the actual needs of outdoor installation scenarios. It can adapt to the gentle curves of building facades as well as the curved contours of columnar carriers, greatly improving the product's scenario adaptability and practicality. This provides reliable technical support for the flexible installation and optimized display effect of outdoor advertising screens.

[0044] In other words, by constructing an integrated structure with multiple sub-bases 210 linked together, rotating guide rails 240 guiding, and adjustment components 300 adapting to the direction, the function of flexibly switching between horizontal and vertical bending can be achieved without removing the display screen body, simply by adjusting the direction of the adjustment components 300. This greatly simplifies the direction switching operation in outdoor scenarios and adapts to diverse installation needs such as curved building facades, columnar carriers, and temporary exhibition venues. At the same time, it provides a stable and precise structural foundation for adjusting the curvature of the display screen, taking into account both the reliability of bending deformation and the stress safety of the display panel 100, and adapting to long-term use in complex outdoor environments.

[0045] In one embodiment, each sub-base 210 has a snap-fit ​​211 and / or a slot 212 on its periphery. Two adjacent sub-bases 210 are connected by snap-fits 211 and slots 212 and are rotatably connected. The snap-fit ​​design, with snap-fits 211 and / or slots 212 on the periphery of the sub-base 210, connects adjacent sub-bases 210. Compared to traditional splicing methods, this snap-fit ​​structure requires no additional tools for initial fixing, meeting the needs of rapid outdoor installation. Furthermore, the "snap-fit ​​and rotatable" design ensures a stable connection without restricting the rotational freedom of the sub-base 210, ensuring smooth and uninterrupted rotation when the adjustment component 300 drives the sub-base 210, and preventing damage to the display panel 100 due to a rigid connection structure. In other embodiments, adjacent sub-bases 210 can also be hinged together using a hinge structure.

[0046] In one embodiment, the sub-base 210 in the middle of the bending base 200 is provided with a clearance hole to allow the conductive wire harness of the display panel 100 to pass through. The control module of the adjustable bending display screen is not located in the bending base 200. The control module can be set to the support frame of the adjustable bending display screen or the control modules of multiple adjustable bending displays in the central control center through a tightening ring or fastener. The conductive wire harness is electrically connected to the control module or the central control center.

[0047] In one embodiment, the bending base 200 includes a longitudinal selection component 220 and a transverse selection component 230. The longitudinal selection component 220 is used to fix the longitudinally adjacent sub-bases 210, and the transverse selection component 230 is used to fix the transversely adjacent sub-bases 210. On the same bending base 200, when the longitudinal selection component 220 is used, the adjustment component 300 rotates on the rotation guide rail 240 to the transverse adjustment position to adjust the rotation angle of the transversely arranged sub-bases 210; when the transverse selection component 230 is used, the adjustment component 300 rotates on the rotation guide rail 240 to the longitudinal adjustment position to adjust the rotation angle of the longitudinally arranged sub-bases 210. By fixing the adjacent sub-bases 210 in the vertical and horizontal directions respectively using the longitudinal selection component 220 and the lateral selection component 230, a clear directional fixing logic is established. The adjustment component 300 can be rotated to the corresponding lateral or longitudinal adjustment position to selectively drive the rotation of the sub-base 210 in the corresponding direction, achieving a closed-loop operation of fixing the selection component, rotating the adjustment component 300, and precise adjustment. This design avoids mutual interference during horizontal and vertical adjustments, ensuring precise and controllable bending shape. In other embodiments, the longitudinal selection component 220 and the lateral selection component 230 may be omitted. In this case, diagonal bending adjustment of the rectangular display screen can be achieved.

[0048] In one embodiment, the longitudinal selection component 220 includes a longitudinal connecting hole 221 and a first connecting rod. The longitudinal connecting hole 221 extends longitudinally through the sub-base 210. Each sub-base 210 has at least two longitudinal connecting holes 221. The first connecting rod passes through at least two longitudinal connecting holes 221 of adjacent sub-bases 210. The transverse selection component 230 includes a transverse connecting hole 231 and a second connecting rod. The transverse connecting hole 231 extends transversely through the sub-base 210. Each sub-base 210 has at least two transverse connecting holes 231. The second connecting rod passes through at least two transverse connecting holes 231 of adjacent sub-bases 210. The longitudinal selection component 220 and the transverse selection component 230 adopt a structure in which connecting holes and connecting rods cooperate. The first connecting rod passes through the longitudinal connecting hole 221 of the adjacent sub-base 210, and the second connecting rod can pass through the transverse connecting hole 231 of the adjacent sub-base 210, forming a rigid support. This ensures that the sub-base 210 always maintains coaxial rotation during bending adjustment, avoiding offset and swaying, and improving bending accuracy. Compared with traditional complex splicing structures, the design and processing of connecting holes and connecting rods are simpler and more cost-effective. In case of partial damage, the first connecting rod, the second connecting rod, or the sub-base 210 can be replaced individually without disassembling the entire screen, greatly reducing the difficulty of outdoor on-site maintenance. Furthermore, when the first or second connecting rod passes only between the longitudinal connecting holes 221 or the transverse connecting holes 231 of two adjacent sub-bases 210, the side of the bending base 200 away from the display screen is provided with a toggle latch 211 connected to the first and second connecting rods. By toggling the latch 211, the stroke of the first or second connecting rod is adjusted so that the first or second connecting rod can be inserted into or moved away from the longitudinal connecting hole 221 or the transverse connecting hole 231 accordingly. In other embodiments, the longitudinal selection component 220 and the transverse selection component 230 may include electromagnetic adsorption, that is, by setting an electromagnet between adjacent sub-bases 210 and changing the positive and negative poles of the electromagnet, the sub-base 210 can be switched between being fixed laterally or longitudinally.

[0049] In one embodiment, both the first connecting rod and the second connecting rod include a connecting end and a free end disposed opposite to each other. The connecting end is connected to the outer wall of the bending base 200. The free end of the first connecting rod penetrates the bending base 200 along a coaxial longitudinal connecting hole 221, and the free end of the second connecting rod penetrates the bending base 200 along a coaxial transverse connecting hole 231. The connecting ends of the first and second connecting rods are connected to the outer wall of the bending base 200, and the free ends penetrate the bending base 200, forming a structure with both ends fixed. Compared with single-end fixing, this significantly improves the connection strength and can resist interference from outdoor wind, vibration, etc., ensuring long-term stability of the bending shape. Furthermore, the connecting end is provided with a connecting protrusion extending circumferentially along the first and second connecting rods. The connecting protrusion can be bolted to the outer wall of the sub-base 210. In other embodiments, the connecting ends of the first and second connecting rods can also be engaged with the end wall of the longitudinal connecting hole 221 or the transverse connecting hole 231.

[0050] In one embodiment, the first connecting rod and the second connecting rod have identical structures. This enables universal interchangeability of the connecting rods in both horizontal and vertical directions, reducing parts inventory and production costs, simplifying outdoor maintenance procedures, and improving product versatility and practicality. In other embodiments, the first connecting rod and the second connecting rod may have different structures.

[0051] In one embodiment, the adjustment assembly 300 includes an arc-shaped fitting assembly 310 and a rotating adjustment rod 320. The arc-shaped fitting assembly 310 includes a first connector 311 and a second connector 312. The first ends of the first connector 311 and the second connector 312 are respectively connected to guide rail segments 241 on different sub-bases 210. The second ends of the first connector 311 and the second connector 312 are arranged facing each other, and the second ends of the first connector 311 and the second connector 312 are connected by the rotating adjustment rod 320. Rotating the rotating adjustment rod 320 causes the first connector 311 and the second connector 312 to rotate relative to each other. The first connector 311 and the second connector of the adjustment assembly 300 are respectively connected to the guide rail segments 241 of different sub-bases 210. By rotating the adjustment rod 320, the connectors can be rotated relative to each other, which can precisely control the rotation angle of the sub-base 210, thereby realizing the fine adjustment of the curvature of the display panel 100 and meeting the adaptation requirements of different outdoor arc-shaped carriers. The arc-shaped fitting component 310 is designed to fit the rotating guide rail 240, ensuring smooth and uninterrupted operation of the adjustment component 300 during steering, sliding, and rotation of the drive sub-base 210. This prevents damage to the display panel 100 due to excessive localized stress caused by jamming. Furthermore, the operation of the rotating adjustment rod 320 is simple and intuitive, requiring no specialized tools, and is suitable for rapid adjustment in outdoor settings. In other embodiments, the rotating adjustment rod 320 may not be included.

[0052] In one embodiment, the first ends of the first connector 311 and the second connector 312 are provided with sliders and fasteners. The rotating guide rail 240 includes a guide protrusion 242 protruding from the bending base 200. The bottom of the slider is provided with a groove 313 that matches the guide protrusion 242. The fastener passes through the slider and extends into the groove 313 to lock the slider and the guide protrusion. The groove 313 at the bottom of the slider matches the guide protrusion 242 of the guide rail, providing guidance for the sliding of the adjustment component 300, ensuring accurate sliding trajectory and avoiding deviation. The fastener passes through the slider and extends into the groove 313 to lock the slider and the guide protrusion 242. It can lock the position after adjustment to prevent the adjustment component 300 from shifting due to wind, vibration and other factors, and ensure long-term stability of the bending shape. At the same time, the cooperation structure between the slider and the guide protrusion 242 can reduce sliding friction, improve adjustment smoothness, and further protect the display panel 100 from damage. In other embodiments, the guide protrusion 242 may be provided with a toothed structure, and the groove 313 may be provided with an elastic retaining bead corresponding to the toothed structure.

[0053] Furthermore, the gap between adjacent guide rail sections 241 is 2 to 3 millimeters, which can prevent the sub-base 210 from colliding and interfering with each other when rotating, and at the same time reduce the impact of dust accumulation on rotation; the length of the slide 313 is greater than 5 millimeters, providing sufficient travel for the adjustment component 300, ensuring that the sub-base 210 in different positions can be driven to rotate, and improving the flexibility and adaptability of bending adjustment.

[0054] In one embodiment, the rotation angle between two adjacent sub-bases 210 is between 20° and 40°. This range is suitable for the bending requirements of common scenarios such as curved exterior facades of outdoor buildings and curved surfaces of street lamp poles, which avoids stress damage to the display panel 100 due to excessive rotation angle, while ensuring bending adaptability.

[0055] In one embodiment, the adjustable bending display screen further includes edge connectors 250, on which an assembly mechanism 251 is provided. The assembly mechanism 251 fixes the edge connectors 250 on different adjustable bending display screens, thereby enabling the assembly of multiple adjustable bending display screens. Specifically, when the overall shape of the bending base 200 is rectangular, the number of edge connectors 250 is six. Four edge connectors 250 are respectively matched and connected to the four corners of the bending base 200, and two edge connectors 250 are located on opposite side edges of the bending base 200 and connected to the central sub-base 210 located on the side edges. The edge connectors 250 and the assembly mechanism 251 on the edge connectors 250 simplify the installation process of large outdoor advertising screens, while facilitating independent transportation and on-site assembly of individual screens, solving the problems of cumbersome installation and difficult transportation of existing large advertising screens. Based on this, the layout of six edge connectors 250 designed for the rectangular bending base 200 forms a three-dimensional fixing system with four-corner positioning and central reinforcement. After splicing, rectangular bases are prone to weak stress, dents, or warping in the middle of the side edges. The central connector directly connects to the sub-base 210, transferring splicing stress to the core structure of the base, rather than concentrating it at the edges. This avoids morphological distortion caused by uneven stress after multi-screen splicing, and is especially suitable for curved splicing scenarios, ensuring overall surface smoothness. The six edge connectors 250 can be independently disassembled. When a single screen malfunctions, there is no need to disassemble the entire splicing structure; only the corresponding edge connector 250 needs to be removed for replacement or repair, significantly reducing maintenance costs and downtime for large outdoor advertising screens. In summary, this edge connector 250 layout retains the core advantages of rapid multi-screen splicing while specifically addressing the accuracy, stress, and stability issues of rectangular adjustable base 200 splicing, perfectly meeting the installation and long-term use needs of large outdoor adjustable advertising screens. In other embodiments, the edge connectors 250 may have eight pieces, with four edge connectors 250 respectively matched and connected to the four corners of the bending base 200, and the four edge connectors 250 are respectively disposed on the four sides of the bending base 200 and connected to the middle sub-base 210 located on the side edge.
