Description

Technical Field

[0001] This invention relates to an LED display installation structure and method, particularly a curved LED display installation structure and a curved structure installation method. Background Technology

[0002] LED display technology is increasingly being adopted in the screen display field, especially in large-size and irregularly shaped display applications, where it demonstrates significant advantages. Large-size (radius from several meters to tens of meters) curved LED displays are widely used in commercial displays, stage performances, and virtual reality scenarios due to their immersive visual experience and high display quality.

[0003] Currently, curved LED displays are mainly installed using a planar cabinet splicing method, which involves dividing the spherical surface into several small planar areas and splicing the planar cabinets to form a spherical structure. However, due to the angular differences between the planar cabinets, problems such as misalignment of the lamp panels and obvious gaps can easily occur after splicing, resulting in discontinuities and black lines in the displayed image, affecting the overall visual effect.

[0004] Meanwhile, the bracket structure used in traditional installation methods is relatively complex, the installation and disassembly process is cumbersome, and the maintenance cost is high, making it difficult to meet the needs of efficient construction and subsequent maintenance, which further limits the promotion and application of curved LED displays.

[0005] Therefore, in order to address the above problems, there is an urgent need to propose a new installation structure and method that is structurally sound, easy to install, and can ensure the flatness of the curved surface and the display effect, so as to meet the growing market demand and the needs of technological progress. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a curved LED display installation structure and installation method that effectively avoids splicing gaps and misalignment and improves the overall display effect.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: This invention first provides a curved LED display screen mounting structure, comprising: The keel layer is a grid structure composed of multiple keel warp lines and multiple keel weft rings; A curved mounting plate layer is fixed to the inner surface of the keel layer; the curved mounting plate layer is composed of curved mounting plates spliced ​​together; the curved mounting plate has a curved surface that is the same as the corresponding position of the curved LED display screen; as well as LED light panel layer, the LED light panel layer is installed on the inner surface of the curved mounting plate layer; the LED light panel layer is spliced ​​together from LED light panels; N*M LED light panels are installed on each curved mounting plate, where N≥2 and M≥2.

[0008] The keel weft ring is composed of alternating steel strips and connecting parts, with the keel warp fixed to the connecting parts. The steel strips and connecting parts are integrally designed and molded, which can precisely ensure the accurate alignment of components such as the keel warp, reinforcing rods, and keel weft ring backing beams at spatial intersections. This avoids installation errors caused by the use of independent mounting flanges in traditional methods, effectively improving assembly efficiency and joint strength, and ensuring the long-term stability of the structural integrity and geometric accuracy.

[0009] A positioning structure for connecting the keel warp is provided on the connecting part.

[0010] The positioning structure is a positioning hole, a positioning line, or a positioning plate.

[0011] The LED light panel is magnetically attached to the curved mounting plate.

[0012] The keel warp is arc-shaped or a near-arc shape formed by connecting several straight segments, and the keel weft ring is arc-shaped or a near-arc shape formed by connecting several straight segments; the keel warp is a rectangular steel pipe; a keel weft ring liner beam, on the same plane as the rectangular steel pipe, is provided below the keel weft ring. The keel weft ring liner beam enhances the strength of the keel weft ring, prevents deformation under stress, and thus further enhances the structural strength of the keel layer, better serving as a stable support.

[0013] The curved mounting plate is a grid plate; one LED light panel is installed on each grid of the grid plate.

[0014] The curved mounting plate is obtained by molding a single sheet material and then cutting it. First, it is molded into an arc shape, then cut to form a grid pattern. This results in a single, strong grid plate. Furthermore, molding before cutting avoids deformation during molding, ensuring high precision in the final grid plate.

[0015] One of the curved mounting plates is installed on each grid of the keel layer.

[0016] Reinforcing rods are provided within the grid structure of the keel layer.

[0017] The primary function of the keel layer is to support the overall structure, ensuring it can bear the load and prevent surface deformation or even collapse. Rectangular steel pipes are used for the keel meridian, providing both high load-bearing capacity and protection against lateral torque deformation. The radius of each layer varies regularly along the latitude direction. The keel latitude rings ensure that the radius and curvature of each layer meet design requirements, thereby guaranteeing the installation stability and curvature accuracy of curved mounting plates, LED light panels, etc. Simultaneously, using steel strips for the keel latitude rings reduces the overall structural weight and facilitates the integration and design of connection structures. A keel latitude ring support beam is installed below the keel latitude rings to enhance their strength and prevent deformation under stress, which would affect accuracy.

[0018] The present invention also provides an installation method for a curved LED display screen mounting structure, comprising: Install a keel layer consisting of keel warp and keel weft rings; Fix the curved mounting plate layer to the inner surface of the keel layer; The LED light panel is mounted on the inner surface of the curved mounting plate.

[0019] The method for installing the keel layer, which consists of keel warp and keel weft rings, is as follows: First, assemble the keel weft rings; Position the keel using the connecting part on the keel weft ring, and then attach the keel warp to the connecting part of the keel weft ring.

[0020] The splicing line between two adjacent curved mounting plates of the curved mounting plate layer is located on the center line of the keel meridian.

[0021] The splicing line between two adjacent LED panels in the LED panel layer is located on the center line of the grid strip.

[0022] The curved LED display installation structure provided by this invention includes an LED light panel, an integrated curved mounting plate, and a segmented molded keel. The curved design of the integrated curved mounting plate allows the LED light panel to fit snugly against the curved structure, effectively avoiding splicing gaps and misalignment, thereby improving the overall display effect. Simultaneously, the molded keel possesses high structural strength and good curved surface adaptability, simplifying the complexity of the installation bracket and enabling rapid installation and disassembly, significantly improving construction efficiency and maintenance convenience. Through optimized structural design, this invention not only ensures the flatness and consistency of the curved LED display but also reduces the impact of installation errors on display quality, possessing broad application prospects and promotional value.

[0023] This invention further proposes an efficient installation method. Through standardized modular design, the components can be quickly assembled and disassembled, significantly reducing on-site construction difficulty and time costs. During installation, the integrated curved mounting plate can be pre-adjusted according to the spherical curvature to ensure that the LED light panel fits the curved structure, maintaining a flat and gapless splicing. Simultaneously, the integrally molded keel uses high-strength, lightweight materials, which not only improves structural stability but also facilitates handling and on-site installation. This method is applicable to curved LED displays of different sizes and curvatures, possessing good versatility and scalability, providing reliable support for the widespread application of irregularly shaped LED display structures.

[0024] The curved LED display screen adopts a three-layer curved structure, including an LED light panel layer, a curved mounting plate layer, and a keel layer. The LED light panel layer is fixed to the inner surface of the curved mounting plate layer, while the keel layer serves as the overall support structure, located on the outer surface of the curved mounting plate layer and tightly connected to it. Through the synergistic effect of the three layers, the precise fit of the LED light panel on spherical surfaces with different curvatures is ensured, avoiding visual defects caused by splicing angle deviations.

[0025] The LED light panel is fixed to the inner surface of the curved mounting plate and installed without holes through strong magnetic adsorption. This avoids the stress deformation and splicing errors caused by traditional screw fixing and further improves the overall smoothness and aesthetics of the display surface.

[0026] The curved mounting plates are manufactured using high-precision molds, ensuring that the curvature of each plate meets design requirements, thus achieving seamless splicing and a flat display of the LED light panels. Simultaneously, the integral molding of the curved mounting plates improves the structural strength and stability of the overall mounting bracket, reducing the risk of deformation due to external forces or temperature changes. Furthermore, the integral molding of the curved mounting plates enhances installation accuracy and reliability, improves installation efficiency, facilitates standardized design and production, reduces installation and maintenance difficulty, and lowers production and construction costs.

[0027] The curved mounting plates are formed using precision molds. During the forming process, it is ensured that the curvature of each mounting plate is highly consistent with the design parameters, thereby effectively avoiding splicing misalignment and display distortion problems caused by curvature deviations.

[0028] The curved mounting plate, after being pressed and molded, is cut and shaped using laser cutting technology. This ensures that the connection holes between each component perfectly align with the splicing edges, further improving the assembly accuracy and stability of the overall structure.

[0029] When the keel meridian is curved, a rectangular tube integral bending forming technology is adopted. By controlling the bending radius and curvature, the perfect fit between the keel meridian and the curved mounting plate is ensured, and the stability and load-bearing capacity of the main structure are guaranteed.

[0030] The keel weft rings are made of high-strength iron plates, bent into a single piece, forming a spatial force-bearing system with the keel warp lines, enhancing the rigidity and stability of the overall structure. The keel weft rings are processed using high-precision molding equipment to ensure that each arc node is completely consistent with the design model, thereby achieving precise positioning and efficient assembly of the keel system in three-dimensional space.

[0031] The keel layer and the curved mounting plate layer are fixed together using riveting, ensuring a firm and reliable connection while avoiding the deformation and stress concentration problems that may occur with welding. Riveting not only improves the overall stability of the structure but also enhances the collaborative load-bearing capacity between components, thereby effectively improving the safety and durability of the entire installation system. Furthermore, riveting facilitates disassembly and replacement, which is beneficial for later maintenance and repair, further reducing maintenance costs and time.

[0032] Advantages of the present invention 1. This invention provides a curved LED display installation structure and a curved installation method. By connecting three layers—LED lamp board layer, curved mounting plate layer, and keel layer—the installation accuracy and structural stability of the curved LED display can be effectively improved, the overall mounting bracket structure can be simplified, installation efficiency can be increased, and construction difficulty can be reduced.

[0033] 2. This invention provides a curved mounting plate structure. Through the application of precision mold pressing and laser cutting technologies, the curvature and hole accuracy of the mounting plate are greatly improved, ensuring the flatness of the overall splicing and the stability of the display effect.

[0034] 3. This invention provides a one-piece molded curved surface mounting plate structure, which not only simplifies the structural design of the mounting bracket and avoids the complex structure of conventional cabinet methods, as well as the cumbersome installation steps and high on-site debugging requirements, but also significantly improves installation efficiency and structural stability. The one-piece molded curved surface mounting plate undergoes high-precision pre-assembly verification during manufacturing, ensuring seamless connection and high degree of matching between components during on-site installation, further reducing the impact of accumulated installation errors on display effects.

[0035] 5. This invention provides an integrally molded curved surface mounting plate structure, which can better adapt to the installation requirements of spherical surfaces with different radii of curvature, and has stronger versatility and flexibility.

[0036] 6. This invention provides a strong magnetic adsorption method for installing LED light panels, which causes the LED light panels to undergo slight elastic deformation, making them more tightly attached to the surface of the curved mounting plate, thereby improving the overall flatness and visual consistency of the display surface.

[0037] 7. This invention provides a strong magnetic adsorption method to fix the LED light board to a curved mounting plate, making the installation and removal of the light board more convenient and improving maintenance efficiency. It also allows for easy adjustment of the LED light board's installation angle and position to adapt to different curved surface shapes, avoiding problems such as image breaks and black lines, further enhancing the flexibility and adjustability of the display screen installation. This method effectively avoids the stress concentration problems that may arise from traditional screw fixing, thereby further improving the overall safety and reliability of the display screen.

[0038] 8. This invention provides a high-strength, high-stability keel layer structure. Through integral molding process and rectangular tube bending forming technology, and through the spatial force system formed by the keel weft rings and keel warp lines, the load-bearing capacity and structural rigidity of the keel system are effectively improved, ensuring the stable operation of the display screen in complex environments.

[0039] 9. This invention provides a keel weft ring structure formed by integral bending, which can better adapt to changes in surface curvature and avoid structural gaps and deformation problems caused by segmented splicing. Through an integrated molding process, the keel weft ring completes high-precision surface matching during the design and manufacturing stage, ensuring the accurate positioning of each connection node in space, and greatly enhancing the stability and deformation resistance of the overall structure.

[0040] 10. This invention provides an integrally bent keel ring structure, simplifying the cumbersome process and precision control problems of traditional splicing structures. For example, it eliminates the need for independent flange structures required for traditional keel installation, and the connection structure is integrally designed and formed on the keel ring, significantly improving on-site installation accuracy and production efficiency. By adopting one-time molding technology, not only are processing steps and material waste reduced, but manufacturing costs are also effectively lowered.

[0041] 11. This invention provides a rectangular tube integrally bent keel warp structure. Through high-precision molds and bending processes, the keel warp more closely conforms to the curvature of a spherical surface, ensuring the coordination and stability of the keel structure in spatial distribution. This structure exhibits more uniform stress distribution, avoiding structural fatigue and deformation problems caused by localized stress concentration, thereby significantly improving the durability and safety of the overall support system. Through high-precision processing and optimized material design, the keel warp maintains stable mechanical properties and geometric accuracy in complex environments, further ensuring the smoothness and consistency of the display screen surface.

[0042] 12. This invention provides an application of a riveting connection method for curved LED displays. By adopting a riveting connection structure, the connection between each connecting component is more stable and reliable, avoiding deformation problems caused by welding, greatly improving the reliability and maintainability of the installation system, and extending the service life of the overall structure.

Detailed Implementation Example

[0044] The embodiments of the present invention will be further described in detail below through implementation and in conjunction with the accompanying drawings.

[0045] This invention provides a curved LED display installation structure for mounting curved LED displays, wherein the curved LED displays include spherical, elliptical, and other curved surface forms. A schematic diagram of the overall structure of the curved LED display installation structure is shown below. Figure 1 As shown, the structure includes a keel layer 1, a curved mounting plate layer 2, and an LED light panel layer 3. The keel layer 1 is a grid structure composed of multiple keel meridians 4 and multiple keel weft loops 6. The keel meridians 4 and keel weft loops 6 all have the same curvature as the curved surface. The grid shape of the keel layer 1 is approximately an isosceles trapezoid. (See [reference needed]). Figure 3 The grid size is L*H, where L is the length of the grid keel along the meridian direction, and H is the length of the grid keel along the weft direction corresponding to the base of the trapezoid. The grid size varies depending on its location; the size at the top is smaller, with a minimum of L*H = 800*200mm; the size at the bottom is larger, with a maximum of L*H = 3000*1500mm. The grid size is not limited to 800*200mm and 3000*1500mm and can be adjusted arbitrarily according to actual needs.

[0046] The curved mounting plate layer 2 is assembled from curved mounting plates 21. The curved mounting plate 21 is molded and cut from a single piece of iron plate. The thickness of the steel plate is 3-5mm, and the size of the overall steel plate is generally 1000*2000mm or 1500*3000mm. However, it is not limited to these two sizes.

[0047] The curved mounting plate layer 2 is fixed to the inner surface of the keel layer 1, and one curved mounting plate 21 is installed on each grid of the keel layer 1. The curved mounting plate layer 2 is stressed synchronously with the keel structure, thereby effectively improving the rigidity and stability of the overall structure.

[0048] LED light panel layer 3 is composed of LED light panels 31 spliced ​​together. LED light panel layer 3 is installed on the inner surface of curved mounting plate layer 2, and N*M LED light panels 31 are installed on each curved mounting plate layer 2, where N≥2 and M≥2.

[0049] This invention relates to a curved LED display installation structure. By installing a curved mounting plate 21 on each grid of the keel layer 1, the flat surface of the grid of the keel layer 1 is transformed into a curved surface. This makes the LED light panel layer 3 installed on the curved mounting plate layer 2 more closely resemble the required curved surface, such as a sphere. This solves the problem of misalignment and obvious gaps that easily occur after splicing the LED light panels 31, avoiding discontinuities and black lines in the displayed image, and greatly improving the overall visual effect. At the same time, the bracket structure used in traditional installation methods is relatively complex, the installation and disassembly process is cumbersome, and the maintenance cost is high, making it difficult to meet the needs of efficient construction and subsequent maintenance.

[0050] LED light panels are typically 320*160mm, but the size can be adjusted as needed. Figure 1 In one embodiment, 3*4 LED light boards 31 are installed on each curved mounting plate layer 2, i.e., N=3, M=4.

[0051] The keel weft ring 6 is an integrated structure consisting of a steel strip 61 and a connecting part 62. The keel weft ring 6 is used to connect the keel warp threads 4. The integrated structure can be formed by stamping or cutting.

[0052] The keel warp wire 4 is fixed to the connecting part 62, either by riveting, bolting, or welding. The connecting parts 62 connect the keel warp wires 4 to form a stable spatial grid structure, such as... Figure 2 As shown. A keel weft ring liner beam 7 is installed below the keel weft ring 6 to increase the strength of the keel weft ring 6. Additionally, reinforcing rods 5 can be added if necessary to further enhance the structural strength and stability.

[0053] A positioning structure for connecting the keel warp line 4 is provided on the connecting part 62. The positioning structure may include positioning holes, positioning lines, or positioning plates. The connecting part 62 also includes a positioning structure for connecting the reinforcing rod 5 and the keel weft ring liner 7. In one embodiment, the positioning structure uses positioning mounting holes, including a keel warp line mounting hole 621, a reinforcing rod mounting hole 622, and a keel weft ring liner mounting hole 623. See [reference needed]. Figure 4 .

[0054] The curved mounting plate layer 2 and the keel layer 1 are fixed by riveting, but can also be connected by screws, clips, etc.

[0055] The LED light panel layer 3 is detachably mounted on the inner surface of the curved mounting plate layer 2 via magnetic adsorption, ensuring quick installation and precise positioning. Magnetic adsorption not only improves installation efficiency but also facilitates later maintenance and replacement. The LED light panel layer 3 can also be mounted on the inner surface of the curved mounting plate layer 2 using other methods, such as snap-fit ​​installation.

[0056] The installation method of the present invention includes the following steps: First, process the keel layer 1 according to the design requirements of the curved LED display (such as the radius of the sphere) to ensure that the dimensional accuracy of the keel meridian 4 and the keel weft ring 6 matches the curvature; Secondly, the curved mounting plate layer 2 is fixed to the inner surface of the keel layer 1 to ensure that it is stressed synchronously with the keel structure; Then, the LED light panel layer 3 is mounted on the inner surface of the curved mounting plate layer 2.

[0057] Throughout the installation process, the combination of high-precision molds and bending technology ensures a tight fit between each layer of the structure, meeting the spherical curvature requirements, thereby achieving stable operation and excellent display effects of the display screen in various environments.

[0058] The curved mounting plate layer 2 is made of a single sheet material (available in various sizes such as 1000×2000mm and 1500×3000mm) pressed into shape using precision molds, and then precisely cut according to design requirements using laser cutting technology. It has good structural strength and curved surface adaptability. Its design fully considers the combination of structural mechanics and material properties, enabling it to evenly distribute stress when subjected to external loads and avoid local deformation affecting the overall shape.

[0059] The curved mounting plate layer 2 is formed by molding a whole plate. The LED light plate layer 3 can be easily adjusted and positioned during installation on the curved mounting plate layer 2 by means of strong magnetic adsorption, thereby ensuring that the splicing gap between each LED light plate is uniform and consistent, and improving the overall display effect.

[0060] The structural design of keel layer 1 fully considers the balance between mechanical support and installation adaptability. Keel warp 4 is formed by integral bending of rectangular tubing, ensuring its curvature matches the overall spherical structure while also guaranteeing its mechanical support performance. Keel weft rings 6 are formed by integral bending of high-strength iron plates, possessing excellent load-bearing capacity and deformation resistance. They effectively support the weight of curved mounting plate layer 2 and LED light plate layer 3, and evenly distribute the load throughout the entire keel space frame structure. Keel weft ring support beams 7 are installed below keel weft rings 6 to further enhance their strength and prevent deformation under stress, thus ensuring structural accuracy.

[0061] The keel warp 4 is connected to the keel weft ring 6 via the connecting part 62 on the keel weft ring 6. Since the connecting part 62 is an integrated structural design on the keel weft ring 6, it can accurately ensure the precise docking of the spatial intersection points of components such as the keel warp 4, the reinforcing rod 5, and the keel weft ring liner beam 7, greatly improving the installation and connection accuracy.

[0062] The intersection of the keel weft ring 6 and the keel warp line 4 is fixed by riveting, ensuring a firm connection without affecting the overall structural integrity. Under wind loads or other external forces, it effectively disperses stress and prevents concentrated deformation. Simultaneously, this structure facilitates on-site assembly and adjustment, improving construction efficiency. Furthermore, the riveting method not only enhances the stability of the connection nodes but also reduces the risk of thermal stress deformation caused by welding, further guaranteeing structural accuracy and service life.

[0063] The installation structure and method for curved LED displays provided by this invention can be used to meet the installation needs of curved LED screens of various sizes, and is also suitable for the installation needs of irregularly shaped curved display structures with different curvatures and application scenarios. Through the combination of modular design and standardized processes, rapid and efficient construction is achieved, while ensuring structural stability and consistency in display effects.

[0064] Through the above design, the present invention not only achieves lightweight structure, but also takes into account the installation requirements of high strength and high precision, providing a reliable support foundation and implementation path for the widespread application of various curvature arc display screens.

[0065] It should be understood that this embodiment is for illustrative purposes only and is not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention. These equivalent forms also fall within the scope defined by the appended claims.
