Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of display screens, and particularly relates to a modular frame and a display screen. BACKGROUND

[0002] Leasing a display screen is a common commercial service, which is suitable for various occasions, such as company activities, product release meetings, exhibition displays, weddings, celebrations, etc. The display screen frame, as an important part of the entire display system, needs to meet a series of requirements in design and manufacturing to ensure the stability, safety, aesthetics, and easy installation and maintenance of the display screen.

[0003] The frame of the leased display screen needs to be frequently disassembled and assembled, which puts higher requirements on the durability and reliability of the frame. If the design is unreasonable or the material quality is not good enough, it may cause problems such as deformation of the frame and loosening of the connecting parts. Although modern LED rental screen frames have tended to be light and thin, the weight of the frame is still a problem for large display screens. A heavier frame not only increases transportation costs, but also may affect the installation speed and labor demand. Most of the current LED display screen frames use aluminum die-casting structure. In the aluminum die-casting process, in order to facilitate demolding, a demolding slope needs to be added, which will increase unnecessary structures. In addition, the die-casting process itself is suitable for producing complex shapes, and in actual application, it tends to design more complex structures to integrate more functions, such as heat sinks, mounting holes, etc., which eventually leads to complex structures and difficult weight control.

[0004] In summary, the existing display screen frame has the drawbacks of complex structure and difficult weight control, resulting in a large amount of labor cost and transportation cost. CONTENT OF THE INVENTION

[0005] Therefore, the embodiments of the present application provide a modular frame and a display screen to solve the technical problem of the existing display screen frame structure being complex and difficult to control the weight, resulting in a large amount of labor cost and transportation cost.

[0006] In a first aspect, the embodiments of the present application provide a modular frame, comprising:

[0007] a support column located in the middle of the modular frame;

[0008] a connecting block distributed on both sides of the support column and located in the corner of the modular frame;

[0009] a plurality of connecting strips detachably connecting the support column and the connecting block, and the support column, the connecting block and the connecting strip are spliced to form the modular frame.

[0010] The existing aluminum die-casting structure usually requires one-time forming of a complex integral frame, which not only requires extremely precise and complex mold design, but also can cause problems such as poor filling and porosity in the production process. The modular frame in the embodiments of the present application adopts a split design, which divides the entire frame into independent components such as support columns, connecting blocks and connecting strips. The shapes of these components are relatively simple, and the manufacturing process is greatly reduced in difficulty. The aluminum die-casting structure needs to realize the integrated forming of all functional modules (such as reinforcing ribs, mounting interfaces, etc.) during casting, increasing the complexity of mold design and manufacturing. The modular frame provided by the embodiments of the present application completes the overall structure by splicing the support columns, connecting blocks and connecting strips, and the functions of each component are clearly divided, without the need for complex internal structure design. In this way, the modular frame provided by the embodiments of the present application effectively saves labor costs and transportation costs.

[0011] In application, the design of the frame allows the size and shape of the frame to be adjusted by increasing or decreasing the number of connecting strips, support columns or connecting blocks, thereby adapting to different application scenarios. The connecting strips, support columns and connecting blocks are connected in a detachable manner, facilitating quick installation and disassembly, and reducing maintenance and transportation costs. At the same time, this design also facilitates the reuse of the frame, in line with the concepts of environmental protection and sustainable development.

[0012] In some embodiments, the modular frame further comprises a support block for controlling the flatness of the modular frame, the support block being fixed to the connecting strip.

[0013] By adopting the above technical solution, the support block is fixed to the connecting strip, which can accurately adjust the overall flatness of the modular frame. By reasonably setting the position and height of the support block, the flatness deviation caused by assembly errors or material deformation can be effectively reduced, ensuring the flatness of the frame surface. The addition of the support block provides additional support points for the connecting strip, enhancing the connection strength between the connecting strip and the support column and the connecting block. This helps to prevent the frame from deforming under stress, thereby improving the stability and anti-deformation ability of the overall structure.

[0014] In some embodiments, a safety rope is slidably provided on the support block, and the safety rope is arranged in parallel with the support column.

[0015] By adopting the above technical solution, the safety rope can move up and down to flexibly adjust the length of the safety rope. The safety rope is arranged in parallel with the support column, which can form a kind of tension balance for the overall frame. This design helps to disperse external forces received by the frame, reducing local stress concentration, thereby enhancing the impact resistance and stability of the entire frame.

[0016] In some embodiments, the safety rope is provided with a pull ring at both ends, and the pull ring is further provided with a buckle.

[0017] By adopting the above technical solution, the design of the pull ring allows the two ends of the safety rope to be conveniently connected with other components or external structures. Through the pull ring, the safety rope can be quickly fixed to the designated position without the need for direct knotting or binding, thereby improving the operation efficiency. The introduction of the buckle further simplifies the connection process, and the fixing can be completed by simply buckling the buckle without the need for additional tools or complex operations. The pull ring allows the two ends of the safety rope to move freely, and the user can adjust the length or position of the safety rope according to actual needs. This flexibility makes the frame more adaptable in different application scenarios. The presence of the buckle makes the installation and removal of the safety rope more convenient.

[0018] In some embodiments, the safety rope end is also provided with a sleeve, and the end of the safety rope is bent and clamped into the sleeve, and the bent part of the safety rope forms the pull ring. In this way, the end of the safety rope can be effectively prevented from protruding and pricking the hand.

[0019] In some embodiments, the support column is also provided with a fixed column on both sides, the fixed column is arranged in parallel with the support column, and the fixed column is connected with the connecting block and the support column through the connecting strip.

[0020] By adopting the above technical solution, the introduction of the fixed column provides an additional support point for the frame, which can effectively disperse external loads and reduce the stress concentration problem of the support column. This design significantly improves the overall rigidity and anti-deformation capability of the frame. The fixed column is connected with the support column and the connecting block through the connecting strip, forming a more stable geometric structure and enhancing the stability of the frame under complex stress conditions.

[0021] In some embodiments, the modular frame further comprises a folding handle, the folding handle comprising:

[0022] a mounting seat arranged on the connecting strip or the fixed column;

[0023] a handle hinged to the mounting seat;

[0024] When the handle is in the folded state, the handle is in the same plane as the support column, and when the handle is in the unfolded state, the handle is perpendicular to the plane in which the support column is located.

[0025] By adopting the above technical solution, the design of the folding handle provides a convenient operation mode for the user. When the frame needs to be moved or adjusted, the handle can be unfolded to facilitate force application, and when it is not needed, the handle can be folded up to avoid occupying additional space.

[0026] In some embodiments, the modular frame is also detachably provided with an arc lock, and the arc lock is used for splicing with an adjacent modular frame.

[0027] By adopting the above technical solution, the design of the radian lock allows adjacent modular frames to be connected at a specific angle or radian, enabling the construction of larger-scale or more complex structures. This design breaks through the limitations of a single frame, allowing multiple frames to be flexibly combined into a whole. By adjusting the angle of the radian lock, users can customize different connection methods according to actual needs, meeting diverse application scenarios.

[0028] In some embodiments, the support column is further provided with a plug at both ends, and the plug connects the connecting block, the connecting strip, and the support column.

[0029] By adopting the above technical solution, the plug integrates and connects the support column, the connecting block, and the connecting strip at both ends of the support column, forming a closed overall structure. This design effectively reduces the risk of loosening or separation between components, improving the overall integrity of the frame. Through the fixing effect of the plug, the connection between the components of the frame is more secure, avoiding structural looseness caused by long-term use or external impact.

[0030] In some embodiments, the support column, the connecting block, and the connecting strip are one of aluminum alloy profiles or magnesium alloy profiles. Using aluminum alloy profiles or magnesium alloy profiles as the main material has the following advantages: first, lightweight, aluminum alloy and magnesium alloy have low density and light weight, suitable for weight-sensitive application scenarios (such as rental display screens, aerospace, etc.). Second, it has high specific strength, which reduces the overall weight while ensuring structural strength. Third, it has good corrosion resistance, suitable for use in harsh environments. These two materials are easy to shape and process, making it easy to manufacture complex profiles.

[0031] In some embodiments, the connecting block is an L-shaped connecting profile, and the two ends of the connecting block are connected to the support column through the connecting strip.

[0032] By adopting the above technical solution, the design of the L-shaped connecting profile allows the connecting block to connect components in two directions (such as support columns and connecting strips) at the same time, forming a stable triangular or rectangular structure. This geometric shape has high anti-deformation ability, significantly improving the overall stability of the frame. The two ends of the connecting block are connected to the support column through the connecting strip, further enhancing the connection strength between the components of the frame and reducing the risk of loosening or separation.

[0033] In some embodiments, the connecting block includes a first connecting part, a second connecting part, and a fixing rib, one end of the first connecting part is vertically arranged at one end of the second connecting part, and the fixing rib connects the first connecting part and the second connecting part.

[0034] By adopting the technical scheme, the first connecting part and the second connecting part are arranged vertically and connected through the fixing rib to form a stable triangular or rectangular geometric structure, so that the rigidity and deformation resistance of the connecting block itself are improved. In addition, the presence of the fixing rib strengthens the connection strength between the first connecting part and the second connecting part, avoiding loosening or separation caused by external force.

[0035] In a second aspect, the embodiment of the present application provides a display screen, comprising:

[0036] The modular frame according to the first aspect;

[0037] The display module, the modular frame is detachably fixed on the display module.

[0038] By adopting the technical scheme, since the display screen has the first aspect, it has all the beneficial effects of the first aspect. In addition, the display screen provided by the present application is easy to assemble and disassemble. Since the modular frame is detachably fixed on the display module, the user can quickly install or replace the modular frame according to the needs without complex tools or steps. The modular frame itself has high expansibility and flexibility, and can be adjusted in size and shape to adapt to different installation environments, thereby meeting diversified needs.

[0062] The first aspect of the embodiments of the present application provides a modular frame, which comprises a support column 10, a connecting block 20 and a plurality of connecting strips 30, as shown in Figures 1 to 3 ,

[0063] The support column 10 is located in the middle of the modular frame;

[0064] The connecting block 20 is distributed on both sides of the support column 10 and located at the corners of the modular frame; the support column 10 is located in the middle, the connecting block 20 is distributed on both sides of the support column 10 and located at the corners of the frame, and they are spliced together by the connecting strips 30 to form a stable geometric structure. This design can effectively disperse external load and enhance the strength and rigidity of the overall frame.

[0065] The plurality of connecting strips 30 detachably connect the support column 10 and the connecting block 20, and the support column 10, the connecting block 20 and the connecting strip 30 are spliced to form a modular frame; the frame adopts modular design, and each component (the support column 10, the connecting block 20 and the connecting strip 30) can be produced and maintained separately, facilitating assembly and disassembly. This design reduces production cost, improves assembly efficiency, and is more convenient when maintenance or replacement is needed.

[0066] The existing aluminum die-casting structure usually needs to be one-time molded into a complex overall frame, which not only requires extremely precise and complex mold design, but also can cause problems such as poor filling and porosity in the production process. The modular frame in the embodiments of the present application adopts a split design, which divides the entire frame into independent components such as support columns, connecting blocks and connecting strips. The shapes of these components are relatively simple, and the manufacturing process is greatly reduced in difficulty. The aluminum die-casting structure needs to realize the integrated molding of all functional modules (such as reinforcing ribs, mounting interfaces, etc.) during casting, increasing the complexity of mold design and manufacturing. The modular frame provided in the embodiments of the present application completes the overall structure by splicing the support columns, connecting blocks and connecting strips, and the functions of each component are clearly divided, without the need for complex internal structure design.

[0067] In application, in the aluminum die-casting structure, in order to ensure strength and rigidity, it is usually necessary to increase the wall thickness or set reinforcing ribs, which will cause material waste and weight increase. The modular frame provided in the embodiments of the present application can be individually optimized according to the specific stress condition, avoiding unnecessary material use. The modular frame allows each component to choose the most suitable material. For example, the support column can choose high-strength aluminum alloy, and the connecting strip can choose lighter magnesium alloy or composite material, thereby reducing the overall weight of the frame. In the aluminum die-casting structure, due to the need for one-time molding, only a single material can usually be used, limiting the lightweight potential. The modular frame allows flexible adjustment of the number and length of the connecting strips according to actual needs, thereby further optimizing the weight distribution on the premise of ensuring strength. In contrast, once the aluminum die-casting structure is formed, it is difficult to modify or optimize it. In summary, the modular frame provided in the embodiments of the present application has a simple structure, is more lightweight and has higher flexibility than the existing aluminum die-casting structure, which is beneficial to enrich the application scenarios.

[0068] Among them, the support column 10, the connecting block 20 and the connecting strip 30 are one of aluminum alloy profiles or magnesium alloy profiles. Using aluminum alloy profiles or magnesium alloy profiles as the main material has the following advantages. First, lightweight, aluminum alloy and magnesium alloy have low density and light weight, which is suitable for weight-sensitive application scenarios (such as rental display screens, aerospace, etc.). Second, high specific strength, which reduces the overall weight while ensuring structural strength. Third, good corrosion resistance, suitable for use in harsh environments. These two materials are easy to form and process, making it easy to manufacture complex profiles.

[0069] In applications, the design of the modular framework allows adjusting the size and shape of the framework by increasing or decreasing the number of connecting strips 30, support columns 10, or connecting blocks 20, thereby adapting to different application scenarios. The detachable connection between the connecting strips 30 and the support columns 10 and connecting blocks 20 facilitates quick installation and disassembly, reducing maintenance and transportation costs. At the same time, this design also facilitates the reuse of the framework, in line with the concepts of environmental protection and sustainable development.

[0070] In some embodiments, a plurality of connecting strips 30 detachably connect the support columns 10 and the connecting blocks 20, and the support columns 10, the connecting blocks 20, and the connecting strips 30 are spliced to form a modular framework. The connection methods include but are not limited to direct connection of the connecting strips 30 to the support columns 10 and the connecting blocks 20, connection of the connecting strips 30 to another connecting strip 30 and the connecting block 20, direct connection of the connecting strip 30 to two connecting blocks 20, and connection of the connecting strip 30 to another connecting strip 30 and the support column 10. The detachable connection methods include but are not limited to clamping, riveting, buckling, magnetic attraction, and screw fixing, etc. This facilitates daily installation and disassembly.

[0071] In applications, the modular framework is in the shape of a grid, rectangle, triangle, etc. The above-shaped framework is beneficial to maintaining the overall stability of the framework and is not prone to deformation.

[0072] In some embodiments, the modular framework further includes a support block 50 for controlling the flatness of the modular framework, and the support block 50 is fixed to the connecting strip 30. The support block 50 is fixed to the connecting strip 30, which can accurately adjust the overall flatness of the modular framework.

[0073] In applications, by reasonably setting the position and height of the support block 50, the flatness deviation caused by assembly errors or material deformation can be effectively reduced, ensuring the flatness of the framework surface. The addition of the support block 50 provides additional support points for the connecting strip 30, enhancing the connection strength between the connecting strip 30 and the support column 10 and the connecting block 20. This helps to prevent the framework from deforming under stress, thereby improving the stability and anti-deformation ability of the overall structure.

[0074] In some embodiments, as shown in Figure 4 The safety rope 60 is slidably provided on the support block 50 and is arranged in parallel with the support column 10. The safety rope 60 can move up and down to flexibly adjust the length of the safety rope 60. The safety rope 60 is arranged in parallel with the support column 10, which can form a kind of tension balance for the overall framework. This design helps to disperse external forces on the framework and reduce local stress concentration, thereby enhancing the impact resistance and stability of the entire framework.

[0075] In applications, the safety rope 60 is usually made of high-strength lightweight materials such as nylon, steel wire rope, etc., which is light in weight and low in cost. Integrating it into the frame design can effectively improve the safety and functionality of the frame without significantly increasing the overall weight, and has a high cost performance.

[0076] In some embodiments, as shown in Figure 5 and Figure 1 , the two ends of the safety rope 60 are provided with pull rings 61, and the pull rings 61 are further provided with buckles 62. This further enhances the functionality, safety and operational convenience of the frame. The design of the pull ring 61 allows the two ends of the safety rope 60 to be easily connected to other components or external structures. Through the pull ring 61, the safety rope 60 can be quickly fixed to the designated position without the need for direct knotting or binding, thereby improving operational efficiency. The introduction of the buckle 62 further simplifies the connection process, and the buckle 62 can be fixed by simply buckling, without the need for additional tools or complex operations. The pull ring 61 allows the two ends of the safety rope 60 to move freely, and the user can adjust the length or position of the safety rope 60 according to actual needs. This flexibility makes the frame more adaptable in different application scenarios. The presence of the buckle 62 makes the installation and removal of the safety rope 60 more convenient.

[0077] In some embodiments, as shown in Figure 4 , Figure 5 and Figures 1 to 3 , the end of the safety rope 60 is also provided with a sleeve 63, and the end of the safety rope 60 is bent and inserted into the sleeve 63, and the bent part of the safety rope 60 forms a pull ring 61. In this way, the end of the safety rope 60 can be effectively prevented from protruding and scratching the hand.

[0078] In applications, the combination of the pull ring 61 and the buckle 62 provides a reliable connection point for the safety rope 60, ensuring that it will not easily fall off during use. The design of the buckle 62 can also prevent the safety rope 60 from loosening or slipping due to external forces, thereby improving the safety performance of the entire frame.

[0079] In some embodiments, as shown in FIG. 6, the two sides of the support column 10 are also provided with fixed columns 40, which are arranged in parallel with the support column 10, and the fixed columns 40 are connected to the connecting block 20 and the support column 10 through the connecting strip 30.

[0080] By adopting the above technical solutions, the introduction of the fixed column 40 provides an additional support point for the frame, which can effectively disperse external loads and reduce the stress concentration problem of the support column 10. This design significantly improves the overall rigidity and anti-deformation ability of the frame. The fixed column 40 is connected to the support column 10 and the connecting block 20 through the connecting strip 30, forming a more stable geometric structure and enhancing the stability of the frame under complex stress conditions.

[0081] In applications, the fixed column 40 is one of a carbon fiber tube or a magnesium alloy profile, an aluminum alloy profile, and in a preferred embodiment, the fixed column 40 is made of a carbon fiber tube. Carbon fiber material has very high specific strength and specific stiffness, and its density is only about one fifth of that of steel, but its strength is much higher than that of steel. Therefore, using a carbon fiber tube as a fixed column 40 can greatly reduce the overall weight of the frame. The carbon fiber tube has excellent tensile strength and bending stiffness and can withstand large external loads without deformation or damage. This makes the frame still maintain stability and reliability under complex stress conditions.

[0082] In some embodiments, as Figure 3 , the modular frame further comprises a folding handle 7270, which is designed to provide users with a convenient operation mode. When the frame needs to be moved or adjusted, the handle 72 can be unfolded for easy force application; and when it is not needed, the handle 72 can be folded up to avoid occupying additional space. The folding design of the handle 72 is not only practical, but also maintains the overall aesthetics of the frame. When the handle 72 is folded, the frame appearance is more concise, which is suitable for application scenarios that require aesthetics.

[0083] In some embodiments, as Figures 1 to 3 , the folding handle 7270 comprises a mounting seat 71 and a handle 72;

[0084] The mounting seat 71 is arranged on the connecting strip 30 or the fixed column 40;

[0085] The handle 72 is hinged to the mounting seat 71;

[0086] When the handle 72 is in the folded state, the handle 72 is in the same plane as the support column 10, and when the handle 72 is in the folded state, the handle 72 is in the same plane as the support column 10, and does not protrude outside the frame. This design effectively reduces the overall volume of the frame, facilitating storage and transportation. When used in a narrow space, the folding handle 7270 will not interfere with other operations, improving the adaptability of the frame. When the handle 72 is in the unfolded state, the handle 72 is perpendicular to the plane in which the support column 10 is located. The folding design of the handle 72 avoids accidental collisions or scratches caused by the protrusion of the handle 72, thereby improving the safety of the frame. In the unfolded state, the handle 72 is perpendicular to the plane in which the support column 10 is located, providing a stable force application point for the user and reducing safety hazards caused by unstable gripping.

[0087] In some embodiments, as Figure 1As shown, the modular frame is also detachably provided with an arc lock 80 for splicing with adjacent modular frames. The design of the arc lock 80 allows adjacent modular frames (two or more) to be spliced at a specific angle or arc, enabling the construction of larger-scale or more complex structures. By splicing multiple modular frames through the arc lock 80, larger-scale or more complex structures can be constructed without the need for additional components. This design effectively improves space utilization and reduces material waste. At the same time, the detachable nature of the arc lock 80 also makes the frame more convenient during storage and transportation, saving space. The arc lock 80 allows users to freely adjust the splicing angle according to actual needs, enabling highly flexible design. Whether it is straight splicing, curved splicing, or multi-angle splicing, it can be easily achieved through the arc lock 80. Detachable arrangements include but are not limited to: using clamping, magnetic attraction, or screw fixation.

[0088] In application, this design breaks through the limitations of a single frame, allowing multiple frames to be flexibly combined into a whole. By adjusting the angle of the arc lock 80, users can customize different splicing methods according to actual needs to meet diverse application scenarios. The modular frame provided in this application adopts a separate arc lock 80 design, which can meet straight screen splicing and arc splicing. Removing the arc lock 80 can achieve 90-degree splicing of the modular frame.

[0089] In some embodiments, as shown, Figure 2 The two ends of the support column 10 are also provided with plugs 90 connected to the connecting blocks 20, connecting strips 30, and support columns 10. The plugs 90 integrate and connect the support columns 10, connecting blocks 20, and connecting strips 30 at both ends of the support column 10, forming a closed overall structure. In a specific embodiment, the plugs 90 connect the support column 10 and the connecting blocks 20 on both sides. In another embodiment, the plugs 90 connect the support column 10 and the connecting strips 30, and the connecting strips 30 are connected to the connecting blocks 20.

[0090] In application, this design effectively reduces the risk of loosening or separation between components, improving the overall integrity of the modular frame. Through the fixing action of the plug 90, the connection between the components of the frame is more secure, avoiding structural looseness caused by long-term use or external impact. The presence of the plug 90 provides additional support points at both ends of the support column 10, effectively dispersing external loads and reducing the stress concentration problem of the support column 10. This significantly improves the overall rigidity and anti-deformation ability of the frame. The plug 90 seals the openings at both ends of the support column 10, effectively preventing dust, moisture, or other foreign matter from entering the inside of the support column 10.

[0091] In some embodiments, the connecting block 20 is an L-shaped connecting profile, and the two ends of the connecting block 20 are connected to the support column 10 through the connecting strip 30. The design of the L-shaped connecting profile enables the connecting block 20 to connect components in two directions (such as the support column 10 and the connecting strip 30) at the same time, forming a stable triangular or rectangular structure.

[0092] In application, this geometry has high deformation resistance, significantly improving the overall stability of the frame. The two ends of the connecting block 20 are connected to the support column 10 through the connecting strip 30, further enhancing the connection strength between the components of the frame and reducing the risk of loosening or separation.
