Description

A box frame and display device Technical Field

[0001] This utility model belongs to the field of display device technology, and in particular relates to a cabinet frame and a display device. Background Technology

[0002] A display screen is a device used to display information such as text, images, video, and recorded signals. Large display screens are usually composed of multiple unit screens, each of which includes a cabinet frame and display modules mounted on that frame.

[0003] In existing cabinet frames, the structure for connecting display modules and the structure for locking adjacent cabinets are usually separate, resulting in a complex overall frame structure. Summary of the Invention

[0004] The technical problem to be solved by this utility model is that, in the existing cabinet frame, the structure for connecting the display module and the structure for locking adjacent cabinets are usually separated, resulting in a complex overall frame structure. This utility model provides a cabinet frame and a display device.

[0005] To address the aforementioned problems, one embodiment of this utility model provides a box frame, including a frame body;

[0006] The main body of the frame is square, and the main body of the frame is provided with connecting seats at least at the four corners;

[0007] The connecting seat has a first side surface and a second side surface opposite to each other along a first direction;

[0008] The first side of the connector is used to connect the display module, and the first side of the connector is provided with a magnetic hole for mounting a magnetic block on the display module.

[0009] The second side of the connecting seat is provided with a mounting position for installing the locking component, so that one of the box frames and the other box frame can be temporarily locked by the locking component.

[0010] In the two connecting seats located at the four corners of the main frame body and spaced apart along the second direction, the distance between the outer edge of one connecting seat and the outer edge of the other connecting seat is 1000 mm;

[0011] In the two connecting seats located at the four corners of the frame body and spaced apart along a third direction, the distance between the outer edge of one connecting seat and the outer edge of the other connecting seat is 1000 mm; wherein, the first direction, the second direction and the third direction are perpendicular to each other.

[0012] Optionally, the frame body includes a pair of first support rods extending along the second direction and a pair of second support rods extending along the third direction; both the first support rods and the second support rods are carbon fiber tubes.

[0013] Optionally, the box frame further includes a mounting beam, which is a magnesium alloy mounting beam; the connecting seat is a magnesium alloy connecting seat;

[0014] The mounting beam is adapted to mount the central control box, and the mounting beam extends along the second direction and connects between a pair of second support rods.

[0015] Optionally, the box frame further includes multiple support beams, which are magnesium alloy support beams;

[0016] The support beam extends along the second direction and connects between a pair of second support rods; a plurality of the support beams are spaced apart along the third direction, and the mounting beam is located between two adjacent support beams in the third direction.

[0017] Optionally, the connecting seat is provided at both ends of the support beam.

[0018] Optionally, the connecting seat is provided at both ends of the mounting beam.

[0019] Optionally, both ends of the mounting beam are provided with first through holes, and the mounting beam is sleeved on the outside of the second support rod through the first through holes;

[0020] Both ends of the support beam are provided with second through holes, and the support beam is sleeved on the outside of the second support rod through the second through holes.

[0021] According to the enclosure frame provided in this embodiment of the utility model, a connecting seat is integrated on the frame body, and the display module is directly connected to the first side of the connecting seat. Simultaneously, a mounting position for the locking component is provided on the second side, thus achieving physical integration of the display module mounting structure and the adjacent enclosure locking structure. Specifically, the display module cooperates with the magnetic block on the display module through a magnetic hole on the first side, using magnetic force to achieve rapid and accurate alignment and reliable fixation of the module. During installation, the magnetic attraction can pre-position the display module, allowing it to be attracted to the predetermined position before complete fixation, facilitating subsequent adjustment and locking. The locking component is installed on the second side of the connecting seat, enabling two adjacent enclosure frames to be temporarily locked together. This integrated structural layout allows the same connecting seat to both support the display module and serve as the basic structure for connecting adjacent enclosures, thereby simplifying the overall frame construction. This application significantly optimizes the frame's structural layout by integrating the display module connection structure and the enclosure locking structure onto the same connecting seat, resulting in a simpler structure and fewer components on the enclosure frame. This invention solves the problems of complex frame structures and numerous components caused by the separation of functional modules in traditional designs. The magnetic holes not only provide a convenient installation method for the display modules, but also, due to the flexibility and pre-positioning characteristics of the magnetic connection—the magnetic force allows the modules to automatically adhere and maintain their position during installation—reducing installation difficulty and improving the accuracy and efficiency of module alignment. On the one hand, this highly integrated design improves the internal space utilization of the frame, making the overall structure simpler and more compact; on the other hand, the simplified structure helps reduce the overall weight of the frame, lowering material costs and reducing transportation and installation difficulties. Simultaneously, the reduction of redundant components also improves the assembly efficiency and structural stability of the frame. Furthermore, this embodiment of the invention establishes a standardized connection reference size of 1000 mm × 1000 mm by placing the connecting seats at the four corners of the square frame body and explicitly defining that the distance between the outer edges of two connecting seats spaced apart along the second direction is 1000 mm, and the distance between the outer edges of two connecting seats spaced apart along the third direction is also 1000 mm. This size design is not arbitrary, but rather addresses the practical needs of modular development in large-scale displays. While ensuring structural stability and splicing accuracy, it overcomes the technical bottleneck of traditional cabinet frames, which struggle to achieve reliable large-span connections due to functional structural separation and insufficient rigidity. This application integrates display module installation and adjacent cabinet locking functions into the four corner connectors, effectively controlling deformation and improving overall flatness even at larger sizes. Understandably, this 1000 mm × 1000 mm layout represents one of the largest standard assembly unit sizes currently capable of stable mass production and engineering applications, possessing significant industrial practical value and thus deserving protection as a key technical feature of this utility model.

[0022] This utility model provides a display device, including a display module, a locking component and the aforementioned housing frame. The display module is provided with a magnetic block. There are multiple display modules and housing frames. The magnetic block on each display module is magnetically connected to the corresponding magnetic hole of the housing frame.

[0023] The locking component is located at the mounting position, and one of the housing frames is temporarily locked to another adjacent housing frame by the locking component.

[0024] Optionally, the display module has a fixing structure on one side facing the connector, and the display module is fixedly connected to the connector through the fixing structure.

[0025] Optionally, the fixing structure is a first fixing hole, and the connecting seat is provided with a second fixing hole opposite to the first fixing hole. Fasteners are inserted into the first fixing hole and the second fixing hole to fix the display module to the connecting seat.

[0026] According to the display device provided in this embodiment of the present invention, by adopting the aforementioned integrated cabinet frame, the display module is installed on the first side of the connecting base, and the locking component is located at the mounting position on the second side of the connecting base. This achieves rapid and precise assembly between the display module and the cabinet frame, as well as convenient temporary locking between adjacent cabinets. On the one hand, the magnetic suction holes allow the display module to be pre-positioned by magnetic attraction during installation, completing the initial alignment without additional auxiliary tools, significantly improving the splicing efficiency and assembly accuracy of multiple display modules. On the other hand, the integrated design of the locking component and the connecting base simplifies the connection structure between adjacent cabinets, making the large-screen splicing process smoother and more stable. This makes the display device of this application simple, compact, and space-efficient, not only reducing the overall weight and manufacturing cost, but also greatly improving the convenience of on-site installation and maintenance, making it suitable for the rapid deployment and reliable operation of various large-scale displays.

[0039] As shown in Figures 1 to 5, an embodiment of the present invention provides a box frame 10, including a frame body 1;

[0040] The main frame 1 is square, and the main frame 1 has connecting seats 2 at at least four corners;

[0041] The connecting seat 2 has a first side and a second side opposite to each other along the first direction;

[0042] The first side of the connector 2 is used to connect the display module 20. The first side of the connector 2 is provided with a magnetic hole 21, which is used for mounting the magnetic block 201 on the display module 20.

[0043] The second side of the connecting seat 2 is provided with a mounting position 22 for mounting the locking assembly 30, so that one box frame 10 and another box frame 10 can be temporarily locked by the locking assembly 30.

[0044] In the two connecting seats 2 located at the four corners of the frame body 1 and spaced apart along the second direction, the distance between the outer edge of one connecting seat 2 and the outer edge of the other connecting seat 2 is 1000 mm;

[0045] Two connecting seats 2 are located at the four corners of the frame body 1, spaced apart along a third direction. The distance between the outer edges of one connecting seat 2 and the outer edges of the other connecting seat 2 is 1000 mm. The first direction, the second direction, and the third direction are perpendicular to each other. The first direction refers to the direction perpendicular to the mounting surface of the display module 20, i.e., the direction from the display module 20 towards the inside or outside of the cabinet. In this embodiment, the first direction is the Y direction in Figure 1. The second direction is the Z direction in Figures 1, 2, and 5, and the third direction is the X direction in Figures 1, 2, and 5. The second direction is the length direction of the frame body 1; the third direction is the width direction of the frame body 1. The "outer edge" refers to the outermost boundary (outer end face) of the connecting seat 2 along the second or third direction, i.e., the edge furthest from the central axis on the end face contour of the connecting seat 2 facing the length direction (second direction) or width direction (third direction) of the frame body 1. This "outer edge" is the physical limit position of the connecting seat 2 in the corresponding direction, used to define its spatial occupancy and installation reference in the cabinet frame 10. In the second direction (length direction), the straight-line distance between the outer edges of the two connecting seats 2 located on the upper and lower sides of the frame body 1 in this direction is measured along the second direction. Referring to Figure 5, the distance between the outer edges of one connecting seat 2 and the outer edge of the other connecting seat 2, which are spaced apart along the second direction at the four corners of the frame body 1, is represented by b, where b equals 1000 mm. Similarly, the distance between the outer edges of one connecting seat 2 and the outer edge of the other connecting seat 2, which are spaced apart along the third direction at the four corners of the frame body 1, is represented by a, where a equals 1000 mm. In the existing cabinet frame 10, the structures for connecting the display module 20 (such as screw holes) and the structures for locking adjacent cabinets (such as lock seats, lock holes, etc.) are usually set in different positions or on different components, and the two are separate and independent of each other. This separate structural layout necessitates additional connectors or supports to bear both functions, complicating the overall structure and increasing the number of parts. This not only increases the weight and manufacturing cost of the frame but also occupies valuable internal space, reducing space utilization and causing inconvenience for assembly and maintenance. This application effectively solves the problems of redundant frame structure and low space utilization caused by the separate arrangement of the two components in the prior art by integrating the structure connecting the display module 20 and the structure for mounting the locking assembly 30 onto the same connector 2.Specifically, the connecting base 2 has a first side and a second side along a first direction (i.e., perpendicular to the mounting surface of the display module 20). The first side is used to connect the display module 20 and is provided with a magnetic suction hole 21, while the second side is provided with a mounting position 22 for mounting the locking component 30. This back-to-back layout of "connecting the module on one side and installing the lock on the other" allows the same connecting base 2 to simultaneously bear the dual functions of supporting the display module 20 and connecting adjacent cabinets, avoiding the structural redundancy of having to set up connecting columns and lock seats separately in traditional designs. On the one hand, the magnetic suction hole 21 can use magnetic attraction to achieve quick pre-positioning and precise installation of the display module 20, improving assembly efficiency. On the other hand, the mounting position 22 on the second side allows adjacent cabinets to be temporarily locked by the locking component 30, and the locking operation is not affected by the installation of the display module 20. Overall, the cabinet frame 10 has a compact structure and high space utilization, which not only reduces the weight of the frame and lowers the manufacturing cost, but also simplifies the assembly process and improves the convenience and reliability of on-site splicing. Meanwhile, the main frame 1 adopts a square closed-loop structure, with integrated connectors 2 at each of the four corners. These connectors serve both for the magnetic installation of the display module 20 and for providing mounting positions 22 for the locking components 30 of adjacent cabinets, achieving a high degree of functional integration. Compared to traditional separate designs, this significantly simplifies the structure, reduces weight, improves space utilization, and enhances splicing accuracy and assembly efficiency. Understandably, the locking components 30 located on the connectors 2 on the left and right sides (i.e., opposite each other along a third direction) can cooperate with the corresponding connectors 2 of adjacent cabinets to reliably and temporarily tighten and lock the cabinets in the third direction (width direction), effectively preventing lateral misalignment after splicing and improving the flatness and structural stability of the entire screen. This design highly integrates the installation of the display module 20 and the multi-directional splicing locking function into the four corner nodes, not only simplifying the overall structure, reducing weight, and improving space utilization, but also significantly enhancing the assembly accuracy and reliability of large displays during horizontal expansion. Furthermore, the distance between the outer edges of two connecting seats 2 located at the four corners of the frame body 1 and spaced apart along the second direction (length direction) is 1000 mm; similarly, the distance between the outer edges of two connecting seats 2 spaced apart along the third direction (width direction) is also 1000 mm. This 1000 mm × 1000 mm layout of the connecting seats 2 is not a conventional choice, but a key technical parameter determined based on the trend of modularization, standardization, and lightweight development of large displays. In existing technologies, the cabinet frame 10 suffers from limited overall rigidity due to the separation of the display module 20 mounting structure from the cabinet locking structure, making it difficult to simultaneously ensure splicing flatness, structural stability, and assembly reliability at large sizes (such as 1000 mm on one side). Most products still use smaller module sizes (such as 500 mm) to avoid the risks of deformation and misalignment.This application integrates dual functions into the four-corner connector 2 and successfully achieves an effective connection span of 1000 mm × 1000 mm without relying on additional reinforcements. This represents the current industry's limit of reliable size while balancing lightweight and high-precision splicing. This size setting has the following significant advantages: 1. Strong standardization and compatibility: 1000mm is a metric standard module, facilitating alignment with external systems such as architecture, stage, and transportation, and benefiting large-scale engineering deployment; 2. High splicing efficiency: A larger single-unit coverage area reduces the number of units required for the entire screen, lowering the total number of seams and installation time. Therefore, the specific dimensional combination of "the spacing of the outer edge of the connector 2 along both the second and third directions is 1000 mm" is one of the core technical features of this utility model for achieving high-performance large-size modular displays. It should be included as an important point of protection in the claims system to prevent competitors from circumventing patent protection by simply copying this size layout. It is understood that structures with the same design but slightly different dimensions are also within the scope of protection of this application.

[0046] As shown in Figures 2 and 3, in one embodiment, the frame body 1 includes a pair of first support rods 11 extending along a second direction and a pair of second support rods 12 extending along a third direction.

[0047] Both the first support rod 11 and the second support rod 12 are carbon fiber tubes. In this embodiment, the strength of carbon fiber tubes is far higher than that of aluminum alloy or steel for the same weight, effectively resisting bending and torsional deformation caused by large dimensions (such as 1000 mm × 1000 mm), ensuring the flatness of the splicing. At the same time, compared with metal materials, carbon fiber has a low density, which greatly reduces the overall weight of the cabinet, making it easier to transport, hoist, and work at height. Using carbon fiber tubes as the main load-bearing support rods not only meets the requirements of large size, lightweight, and high reliability of display cabinets.

[0048] In one embodiment, the box frame 10 further includes a mounting beam 13, which is a magnesium alloy mounting beam; the connecting seat 2 is a magnesium alloy connecting seat;

[0049] Mounting beam 13 is suitable for mounting the central control box 40. Mounting beam 13 extends along the second direction and connects between a pair of second support rods 12. By adding mounting beam 13 extending along the second direction, a reliable mounting position 22 for the central control box 40 is provided, and the structural strength of the frame body 1 is strengthened. The central control box 40 can be formed by a rear cover fitting onto the mounting beam 13. The central control box 40 is equipped with power connectors and signal connectors. It is understood that by setting locking components 30 at both ends, the hoisting or locking of adjacent cabinets in the second direction (i.e., the length direction) is achieved, ensuring reliable fixation of the large display screen in the second direction as well. This layout further distributes the stress, improves the overall stability and flatness when multiple cabinets are spliced, and the one-piece molding design simplifies the manufacturing process and reduces assembly costs. Meanwhile, the box frame 10 employs a hybrid approach, combining carbon fiber tubes (for the first support rod 11 and the second support rod 12) with magnesium alloy (for the mounting beam 13 and the connecting seat 2). Through coordinated design of materials and processes, this approach differs from the conventional approach of using a single material throughout the structure. It ensures overall lightweight and high structural strength while balancing material cost and processing performance, achieving a balance between structural strength, lightweight, and cost. Specifically, the carbon fiber tubes, serving as the main load-bearing frame, provide extremely high specific stiffness and bending resistance, effectively supporting a large span of 1000 mm × 1000 mm without easily deforming. Magnesium alloy is used for local functional components (such as the connecting seat and mounting beam), achieving lightweight while maintaining strength. This combination avoids the excessive weight of an all-metal structure and overcomes the limitations of integrating complex installation structures (such as threads and plug-in joints) with all-carbon fiber. Using all-carbon fiber would require adding metal inserts or post-processing in areas such as the connecting seat, resulting in high costs and significant reliability risks. Using all-magnesium alloy would make it difficult to meet the overall weight and rigidity requirements for large dimensions. The hybrid approach uses high-performance carbon fiber in critical stress paths and easily machinable magnesium alloy in functional integration areas, achieving engineering optimization that is "strong where it needs to be strong, light where it needs to be light, and economical where it needs to be economical."

[0050] In one embodiment, the box frame 10 further includes a plurality of support beams 14, which are magnesium alloy support beams;

[0051] Support beams 14 extend along a second direction and connect between a pair of second support rods 12; multiple support beams 14 are spaced apart along a third direction, and mounting beams 13 are located between two adjacent support beams 14 in the third direction. The spaced arrangement of multiple support beams 14 extending along the second direction effectively enhances the structural strength and rigidity of the frame body 1 and reduces deformation; the mounting beams 13 are arranged between the support beams 14, resulting in a compact and reasonable layout and higher space utilization. Similar to the above embodiment, the box frame 10 uses a hybrid approach of carbon fiber tubes (for the first support rod 11 and the second support rod 12) and magnesium alloy (for the mounting beams 13, support beams 14, and connecting seats 2). Through the synergistic design of materials and processes, unlike the conventional setup of using a single material throughout the existing technology, this approach ensures the overall lightweight and high structural strength of the frame while also considering material cost and processing performance, achieving a balance between structural strength, lightweight, and cost. This embodiment achieves a large-pitch design of 1000 mm by limiting the distance between the outer edges of the connecting seats 2 located at the four corners of the frame body 1 along the second and third directions to a standardized size of 1000 mm. This size is difficult to achieve in existing technologies due to insufficient structural rigidity and difficulty in ensuring splicing accuracy. This application relies on a composite structure of carbon fiber supports and magnesium alloy beams to maintain high rigidity and flatness while ensuring overall lightweighting. This successfully supports large-size module layouts, not only improving the display area and splicing efficiency of a single cabinet, but also providing a reliable and mass-producible standardized foundation for the modular expansion of large displays, demonstrating significant engineering practical value and market competitiveness.

[0052] In one embodiment, the mounting beam 13 has a first through hole at both ends, and the mounting beam 13 is sleeved on the outside of the second support rod 12 through the first through hole;

[0053] Both ends of the support beam 14 are provided with second through holes, through which the support beam 14 is fitted onto the outside of the second support rod 12. The mounting beam 13 and the support beam 14 are fitted onto the outside of the second support rod 12 through the first and second through holes respectively, achieving rapid positioning and preliminary assembly. This through-sleeve structure simplifies the connection method, and the alignment and installation of the beam and support rod can be completed without additional fasteners. After installation, it can be fixed by applying adhesive to the contact area between the beam and the support rod, which not only enhances the overall rigidity and seismic resistance of the structure, but also avoids stress concentration and process complexity caused by drilling or welding, taking into account both assembly convenience and long-term reliability.

[0054] In one embodiment, both ends of the support beam 14 are provided with connecting seats 2.

[0055] The distance between the outer edges of the two connecting seats 2 located at both ends of the support beam 14 is 1000 mm. Connecting seats 2 are provided at both ends of the support beam 14, further increasing the connection points between the display module 20 and adjacent cabinets, improving assembly accuracy and splicing stability. The connecting seats 2 at both ends of the support beam 14 can be integrally formed with the support beam 14. It is understood that the locking components 30 installed on the connecting seats 2 at both ends of the support beam 14 can cooperate with the corresponding structures of adjacent cabinets to achieve tensioning and locking in a second direction, effectively eliminating splicing gaps, suppressing displacement caused by thermal expansion and contraction or vibration, and ensuring the flatness and long-term stability of the entire screen. Furthermore, the connecting seats 2 of the support beam 14 can be integrally formed with the beam body, simplifying manufacturing; the overall structure is compact, with high functional integration, balancing strength, precision, and space utilization. The dimensions between the outer edges of the two connecting seats 2 at both ends of the support beam 14 are not arbitrarily chosen, but are strictly aligned with the 1000 mm × 1000 mm reference module dimensions formed by the four corner connecting seats 2 of the frame body 1, forming a standardized connection grid that fully covers the transverse (third direction) and longitudinal (second direction). By adding connecting seats 2 arranged at 1000 mm intervals on the support beam and the mounting beam, a "multi-point cooperative force-bearing" structure is formed, significantly improving the bending stiffness and flatness control capability of the large-size box.

[0056] In one embodiment, both ends of the mounting beam 13 are provided with connecting seats 2.

[0057] The distance between the outer edges of the two connecting seats 2 located at both ends of the mounting beam 13 is 1000 mm. Connecting seats 2 are provided at both ends of the mounting beam 13, further increasing the connection points of the display module 20 and the locking points of the housing, improving assembly stability and splicing reliability. The connecting seats 2 at both ends of the mounting beam 13 can be integrally formed with the mounting beam 13. The locking components 30 installed on the mounting positions 22 of the connecting seats 2 at the four corners of the frame body 1 are defined as left and right locking components 301; the locking components 30 installed on the mounting positions 22 of the connecting seats 2 on the support beam 14 are defined as upper and lower locking components 302; and the locking components 30 installed on the mounting positions 22 of the mounting beam 13 are positioned as lifting locking components 303. It is understood that the left and right locking components 301, upper and lower locking components 302, and lifting locking components 303 can be selected according to need, and the three can have the same structure or different structures. As described in the above embodiment, the dimensions between the outer edges of the two connecting seats 2 at both ends of the mounting beam 13 are not arbitrarily chosen, but are strictly aligned with the 1000 mm × 1000 mm reference module dimensions formed by the four corner connecting seats of the frame body 1, forming a standardized connection grid that fully covers the transverse (third direction) and longitudinal (second direction). By adding connecting seats 2 arranged at 1000 mm intervals on the mounting beam 13, a "multi-point collaborative force-bearing" structure is formed, significantly improving the bending stiffness and flatness control capability of the large-size box body.

[0058] According to the enclosure frame 10 provided in this embodiment of the utility model, by integrating a connecting seat 2 on the frame body 1 and directly connecting the display module 20 to the first side of the connecting seat 2, and providing an installation position 22 for installing the locking component 30 on its second side, the physical integration of the display module 20 installation structure and the adjacent enclosure locking structure is achieved. Specifically, the display module 20 cooperates with the magnetic block 201 on the display module 20 through the magnetic suction hole 21 opened on the first side, using magnetic attraction to achieve quick and accurate alignment and reliable fixation of the module. During installation, the magnetic attraction can pre-position the display module 20, allowing it to be attracted to the predetermined position before being fully fixed, facilitating subsequent adjustment and locking. The locking component 30 is installed on the second side of the connecting seat 2, allowing two adjacent enclosure frames 10 to be temporarily locked together. This integrated structural layout allows the same connecting seat 2 to both bear the function of the display module 20 and serve as the basic structure for connecting adjacent enclosures, thereby simplifying the overall structure of the frame. This application significantly optimizes the structural layout of the frame by integrating the connection structure of the display module 20 and the locking structure between the cabinets onto the same connector 2. This solves the problems of complex frame structures and numerous components caused by the separation of functional modules in traditional designs. The magnetic holes 21 not only provide a convenient installation method for the display module 20, but also, due to the flexibility and pre-positioning characteristics of the magnetic connection—the magnetic force allows the module to automatically adhere and maintain its position during installation—reducing installation difficulty and improving the accuracy and efficiency of module alignment. On the one hand, this highly integrated design improves the internal space utilization of the frame, making the overall structure simpler and more compact; on the other hand, the simplified structure helps reduce the overall weight of the frame, lowering material costs and reducing transportation and installation difficulties. Furthermore, the reduction of redundant components also improves the assembly efficiency and structural stability of the frame. Furthermore, this embodiment of the invention establishes a standardized connection reference size of 1000 mm × 1000 mm by placing the connecting seats 2 at the four corners of the square frame body 1 and explicitly defining that the distance between the outer edges of two connecting seats 2 spaced apart along the second direction is 1000 mm, and the distance between the outer edges of two connecting seats 2 spaced apart along the third direction is also 1000 mm. This size design is not arbitrary but is tailored to the actual needs of the modular development of large display screens. While ensuring structural stability and splicing accuracy, it overcomes the technical bottleneck of traditional cabinet frames, which are difficult to achieve reliable large-span connections due to functional structural separation and insufficient rigidity. This application integrates the installation function of the display module 20 and the locking function of adjacent cabinets into the four corner connecting seats 2, which can effectively control deformation and improve overall flatness even at larger sizes.Understandably, the 1000 mm × 1000 mm layout size represents one of the largest standard unit sizes currently available for stable mass production and engineering applications, and has significant industrial practical value. It can be protected as a key technical feature of this utility model.

[0059] In addition, this utility model embodiment provides a display device, including a display module 20, a locking component 30 and a housing frame 10 as described in the above embodiment. The display module 20 is provided with a magnetic block 201. There are multiple display modules 20 and housing frames 10. The magnetic block 201 on each display module 20 is magnetically connected to the corresponding magnetic hole 21 of the housing frame 10.

[0060] A locking component 30 is located at the mounting position 22, temporarily locking one cabinet frame 10 to another adjacent cabinet frame 10. Using the integrated cabinet frame 10 described in the above embodiment, multiple display modules 20 are respectively installed on the connecting seats 2 of their corresponding frames, and temporary locking between adjacent cabinets is achieved through the locking component 30 located at the mounting position 22. Both the display module 20 and the locking component 30 utilize existing mature technologies, requiring no additional development, resulting in controllable manufacturing costs and a simple assembly process. The magnetic blocks 201 on the display module 20 achieve rapid pre-positioning and reliable fixation through magnetic holes 21, while the locking component 30 ensures a stable connection when multiple cabinets are spliced—the synergistic effect of both makes on-site installation, disassembly, and maintenance of large displays more efficient and convenient. Overall, this display device, while maintaining a compact and lightweight structure, significantly improves splicing accuracy, assembly efficiency, and reliability, making it suitable for various large-scale and standardized display application scenarios. Understandably, in the display device of this utility model, the magnetic blocks 201 can be set at the four corners or other corresponding positions of the back plate of the display module 20, precisely aligned with the magnetic holes 21 on the connecting seat 2 of the cabinet frame 10. This magnetic connection method is a mature existing technology, with advantages such as tool-free operation, rapid adsorption, automatic centering (pre-positioning), and reliable fixation. By integrating the magnetic blocks 201 into the structural components of the display module 20 (such as the back shell, bracket, or PCB back plate), and cooperating with the magnetic holes 21 of the cabinet frame 10, a "one-click" installation experience can be achieved, greatly simplifying on-site operations. Combined with the equally mature locking component 30, the whole machine ensures high splicing accuracy and structural stability while taking into account efficient assembly and convenient maintenance, making it suitable for large-scale indoor and outdoor large display screen systems.

[0061] In one embodiment, a fixing structure 202 is provided on the side of the display module 20 facing the connecting seat 2, and the display module 20 is fixedly connected to the connecting seat 2 through the fixing structure 202. The fixing structure 202 on the side of the display module 20 facing the connecting seat 2, and the fixed connection between the display module 20 and the housing frame 10 through this fixing structure 202, further enhances the reliability of the connection between the display module 20 and the housing frame 10. This fixing structure 202 can work in conjunction with the magnetic block 201—the magnetic block 201 enables quick pre-positioning and initial fixing, while the fixing structure 202 provides secondary reinforcement, ensuring that the display module 20 will not shift or fall off due to vibration or external force during use. This dual fixing method of "magnetic pre-positioning + fixing structure 202 locking" retains the efficiency and convenience of magnetic installation while improving the stability and safety of long-term use through mechanical fixing. The fixing structure 202 can be designed in various forms such as buckles and screw holes according to actual needs, flexibly adapting to different assembly process requirements.

[0062] In one embodiment, the fixing structure 202 is a first fixing hole, and the connecting seat 2 has a second fixing hole opposite to the first fixing hole. Fasteners are inserted into the first fixing hole and the second fixing hole to fix the display module 20 to the connecting seat 2. In this embodiment, the fixing structure 202 is specifically the first fixing hole, and the connecting seat 2 has a corresponding second fixing hole. By inserting fasteners (such as screws, bolts, etc.) into the first fixing hole and the second fixing hole, a reliable fixed connection between the display module 20 and the connecting seat 2 is achieved. This fixing method of hole and fastener is simple in structure, has high connection strength, and can effectively resist external loads such as vibration and impact, ensuring that the display module 20 remains stable and does not loosen under long-term use or complex working conditions.

[0063] According to the display device provided in this embodiment of the present invention, by adopting the aforementioned integrated cabinet frame 10, the display module 20 is installed on the first side of the connecting base 2, and the locking component 30 is located at the mounting position 22 on the second side of the connecting base 2. This achieves rapid and precise assembly between the display module 20 and the cabinet frame 10, as well as convenient temporary locking between adjacent cabinets. On the one hand, the magnetic suction hole 21 allows the display module 20 to be pre-positioned by magnetic attraction during installation, completing the initial alignment without additional auxiliary tools, significantly improving the splicing efficiency and assembly accuracy of multiple display modules 20. On the other hand, the integrated design of the locking component 30 and the connecting base 2 simplifies the connection structure between adjacent cabinets, making the large-screen splicing process smoother and more stable. This makes the display device of this application simple, compact, and space-efficient, not only reducing the overall weight and manufacturing cost, but also significantly improving the convenience of on-site installation and maintenance, making it suitable for the rapid deployment and reliable operation of various large-scale displays.
