Especially in large outdoor displays, stage backdrops, and stadiums, the application of LED displays is becoming increasingly widespread. LED display devices have advantages such as high brightness, low energy consumption, long lifespan, and wide viewing angles, thus finding widespread use in various scenarios. At the same time, with the continuous improvement of display demands, the market has placed higher requirements on the size, shape, installation methods, and ease of disassembly and maintenance of LED display devices. In particular, some special-shaped and irregularly shaped display devices are increasingly favored in modern commercial and cultural displays, posing more challenges to the design of traditional LED display devices.

[0003] Traditional LED display devices mostly adopt regular rectangular or square designs. While these designs can meet standardized display requirements, they have certain limitations in irregularly shaped display applications. Many existing irregularly shaped LED display device technologies have relatively simple construction methods, typically using a single display module and frame structure. The installation method is fixed, and the overall structure lacks flexibility, making it difficult to adapt to occasions with irregular shapes or complex installation requirements. Disassembly and maintenance are also quite difficult.

[0004] Therefore, there is a need to provide an LED display device to solve the problem of the lack of flexibility in the overall structure of the aforementioned irregularly shaped LED display devices. Utility Model Content

[0005] The main objective of this invention is to provide an LED display device that addresses the technical problems mentioned in the background section.

[0006] The present invention adopts the following technical solution:

[0007] An LED display device includes an LED display module and a main frame, wherein the LED display module is detachably connected to the outer side of the main frame;

[0008] The main frame includes several upper frame units and several lower frame units. The several upper frame units are arranged in a circular arrangement to form a cylindrical upper frame assembly, and the several lower frame units are arranged in a circular arrangement to form a cylindrical lower frame assembly. The upper frame assembly is detachably connected to the upper end face of the lower frame assembly. The number of upper frame units is equal to the number of lower frame units.

[0009] Furthermore, the upper end face of the upper frame assembly is provided with a connecting groove, and a connecting ring is installed in the connecting groove. The connecting ring is used to fix and connect several of the upper frame units.

[0010] Furthermore, the connecting ring has a plurality of tapered countersunk holes, and the connecting groove has threaded holes corresponding to the tapered countersunk holes. Countersunk screws are detachably connected to the tapered countersunk holes and the threaded holes.

[0011] Furthermore, the LED display module includes multiple flexible LED panels, and the upper frame unit and the lower frame unit are provided with mounting holes on the side near the flexible LED panels. The flexible LED panels are provided with fasteners corresponding to the mounting holes.

[0012] Furthermore, a control board is provided on one end face of the flexible LED panel facing the main frame, and both the upper frame unit and the lower frame unit are provided with receiving through holes to accommodate the control board, and the receiving through holes are distributed along the length direction of the upper frame unit and the lower frame unit, respectively.

[0013] Furthermore, it also includes several L-shaped corner connectors. The upper frame unit has an upper connecting beam extending from the side facing away from the LED display module. One side of the upper connecting beam is connected to the corner connector. The upper frame unit is fixedly connected to the adjacent upper frame unit through the corner connector. The lower frame unit has a lower connecting beam extending from the side facing away from the LED display module. One side of the lower connecting beam is connected to the corner connector.

[0027] Reference Figures 1 to 3 The present invention proposes an LED display device, including an LED display module 1 and a main frame 2, wherein the LED display module 1 is detachably connected to the outer side of the main frame 2;

[0028] The main frame 2 includes a plurality of upper frame units 211 and a plurality of lower frame units 221. The plurality of upper frame units 211 are arranged in a circular arrangement to form a cylindrical upper frame assembly 210, and the plurality of lower frame units 221 are arranged in a circular arrangement to form a cylindrical lower frame assembly 220. The upper frame assembly 210 is detachably connected to the upper end face of the lower frame assembly 220. The number of upper frame units 211 is equal to the number of lower frame units 221.

[0029] In the above embodiment, the device includes an LED display module 1 and a main frame 2. The LED display module 1 is disposed on the outer side of the main frame 2 and is detachably installed through a specific connection structure, allowing the LED display module 1 to be quickly disassembled and assembled when needed, thereby facilitating maintenance, replacement, or adjustment of the display content. The main frame 2 is a key component of this device. It adopts a modular design and is composed of several upper frame units 211 and several lower frame units 221. The outer sides of the upper frame units 211 and the lower frame units 221 are all curved, with a fan-shaped cross-section, and are respectively arranged to form a cylindrical upper frame assembly 210 and a lower frame assembly 220. Each frame unit is fixedly connected by connectors. The modular structure between the units not only ensures the stability of the overall frame but also greatly improves the flexibility during production, transportation, and installation.

[0030] The upper frame assembly 210 and the lower frame assembly 220 are connected in a detachable manner, with the upper frame assembly 210 located on the upper surface of the lower frame assembly 220. They are securely assembled using connectors, latches, or bolts, giving the entire frame structure high flexibility and allowing for easy disassembly and maintenance, while meeting the needs of different scenarios. To ensure the aesthetics and structural symmetry of the device, the design ensures that the number of upper frame units 211 and lower frame units 221 are equal. This consistency makes the overall frame more visually uniform and mechanically stable. The specific number can be adjusted according to the actual application requirements for unit configuration.

[0031] In a specific application embodiment, the disassembly requirement for the main frame 2 is not high. It only requires certain requirements for transportation before installation and for the strength of the main frame 2 after installation. Several upper frame units 211 and several lower frame units 221 still exist as individual units before assembly. During installation, each unit is installed by riveting and fixed with rivets. While ensuring the connection strength, it can also effectively avoid thermal deformation caused by welding and other methods.

[0032] In summary, by dividing the main frame 2 into several upper frame units 211 and lower frame units 221, and combining the upper frame units 211 and lower frame units 221 to form cylindrical upper frame components 210 and lower frame components 220 respectively, the overall flexibility of the device is significantly improved, enabling it to adapt to irregularly shaped LED display requirements. Each frame unit can be independently disassembled and assembled, which not only facilitates modular processing during production and transportation, but also allows for rapid assembly or adjustment of the frame components according to actual needs, effectively solving the problem of the lack of flexibility in the overall structure of existing irregularly shaped LED display devices.

[0033] refer to Figure 1 and Figure 2 In one embodiment, the upper end face of the upper frame assembly 210 is provided with a connecting groove 3, and a connecting ring 4 is installed in the connecting groove 3. The connecting ring 4 is used to fixally connect a plurality of the upper frame units 211.

[0034] In the above embodiment, a connecting ring 4 is installed inside the connecting groove 3 on the upper end face of the upper frame assembly 210 to further fix the combined structure of several upper frame units 211. Specifically, the connecting groove 3 is a recessed part on the upper end face of the upper frame assembly 210, and its position and size are adapted to the installation requirements of the connecting ring 4. As a key fixing component, the connecting ring 4 functions to ensure that the entire upper frame assembly 210 has higher integrity and stability after assembly by surrounding and fixing the upper ends of several upper frame units 211.

[0035] The connecting ring 4 makes the connection between the upper frame units 211 more secure, which not only effectively prevents the upper frame assembly 210 from loosening due to vibration or other external forces during use, but also further enhances the load-bearing capacity and durability of the frame. At the same time, the presence of the connecting groove 3 allows the connecting ring 4 to be embedded in it, avoiding its exposure and affecting the appearance, and keeping the frame assembly neat and beautiful.

[0036] refer to Figure 2 In one example, the connecting ring 4 has a plurality of tapered countersunk holes 41, and the connecting groove 3 has threaded holes corresponding to the tapered countersunk holes 41. Countersunk screws are detachably connected to the tapered countersunk holes 41 and the threaded holes.

[0037] In the above embodiment, the conical countersunk holes 41 on the connecting ring 4 are designed in shape and position to mate with the threaded holes in the connecting groove 3. The conical countersunk holes 41 not only facilitate the smooth installation of countersunk screws but also ensure that the screw head is completely recessed into the hole after installation, avoiding safety hazards and aesthetic impact caused by exposed screw heads. The corresponding threaded holes on the connecting groove 3 are for threaded connection with the countersunk screws in the conical countersunk holes 41, thus achieving a secure fixation between the connecting ring 4 and the upper frame assembly 210. Furthermore, the detachable connection between the conical countersunk holes 41 and the threaded holes makes the connection between the connecting ring 4 and the upper frame assembly 210 more flexible, facilitating subsequent disassembly and maintenance.

[0038] refer to Figure 3 In one embodiment, the LED display module 1 includes a plurality of flexible LED panels 101. The upper frame unit 211 and the lower frame unit 221 are provided with mounting holes 5 on the side near the flexible LED panel 101. The flexible LED panel 101 is provided with fasteners corresponding to the mounting holes 5.

[0039] In the above embodiment, the LED display module 1 is composed of multiple flexible LED panels 101, which have high flexibility and splicability, and can be freely combined according to display needs to achieve diverse display effects. Both the upper frame unit 211 and the lower frame unit 221 have mounting holes 5 on the side near the flexible LED panel 101 to ensure that each flexible LED panel 101 can be installed in place. Simultaneously, the flexible LED panel 101 is provided with fasteners corresponding to the mounting holes 5. These fasteners can be screws, clips, or other types of connectors, which can firmly fix the flexible LED panel 101 to the frame, preventing displacement or detachment during use. This not only improves the stability and reliability of the LED display device but also makes the installation and disassembly process simpler and faster, reducing maintenance costs.

[0040] In one embodiment, a control board is provided on one end face of the flexible LED panel 101 facing the main frame 2. Both the upper frame unit 211 and the lower frame unit 221 are provided with receiving through holes 6 for accommodating the control board. The receiving through holes 6 are distributed along the length direction of the upper frame unit 211 and the lower frame unit 221, respectively.

[0041] In the above embodiment, the flexible LED panel 101 not only has a display function but also integrates a control board, making the entire device more compact. The control board is responsible for receiving and processing signals from external sources or preset signals, controlling the brightness and color changes of the flexible LED panel 101 to display images. The upper frame unit 211 and the lower frame unit 221 have corresponding receiving holes 6, distributed along the length of the frame (top to bottom), which can accommodate the control board and ensure that it is not squeezed or damaged during installation. Simultaneously, the receiving holes 6 also facilitate heat dissipation for the control board, extending the lifespan of the LED display device. This embodiment not only optimizes the internal structure of the LED display device but also improves its stability and performance.

[0042] refer to Figure 1 In one embodiment, the device further includes several L-shaped corner connectors 7. An upper connecting beam 212 extends from the side of the upper frame unit 211 facing away from the LED display module 1. The corner connector 7 is connected to one side of the upper connecting beam 212. The upper frame unit 211 is fixedly connected to the adjacent upper frame unit 211 through the corner connector 7. A lower connecting beam 222 extends from the side of the lower frame unit 221 facing away from the LED display module 1. The corner connector 7 is connected to one side of the lower connecting beam 222. The lower frame unit 221 is fixedly connected to the adjacent lower frame unit 221 through the corner connector 7.

[0043] In the above embodiment, the L-shaped corner connector 7 further enhances the stability and robustness of the frame structure. Upper frame unit 211 and lower frame unit 221 extend upper connecting beam 212 and lower connecting beam 222 respectively on the side facing away from the LED display module 1. These connecting beams not only provide a mounting base for the corner connector 7 but also enhance the frame's load-bearing capacity and resistance to deformation. The design of the corner connector 7 allows adjacent upper frame units 211 and lower frame units 221 to be tightly fixed together, forming a complete frame system. This connection method not only simplifies the installation process but also improves the stability and durability of the entire device. Furthermore, the L-shaped design of the corner connector 7 makes the connection more robust, effectively resisting external impacts and vibrations, ensuring that the LED display device maintains good display performance and stability during long-term use.

[0044] In one embodiment, a base 8 is fixedly connected to the lower end face of the lower frame assembly 220, and a plurality of lamp holes 9 are provided on the side of the base 8, each of which is equipped with an indicator light.

[0045] In the above embodiment, a base 8 is fixedly mounted on the lower end face of the lower frame assembly 220. The base 8 has multiple lamp holes 9 on its side, which are evenly distributed, satisfying both aesthetic requirements and ensuring the rationality of the installation position and number of indicator lights. Each lamp hole 9 houses an indicator light, which provides status indications such as power status and operating mode when the LED display device is working, allowing users to intuitively understand the device's operation. Furthermore, the design of the base 8 not only enhances the stability of the entire device but also makes the installation and fixing of the LED display device more convenient.

[0046] In one embodiment, the bottom end of the base 8 is provided with a receiving groove, and a plurality of universal wheels 10 are provided at equal angles in the receiving groove, with the bottom end of the universal wheels 10 protruding from the lower end surface of the base 8.

[0047] In the above embodiment, the receiving groove at the bottom of the base 8 utilizes the space of the base 8 and also makes the installation of the casters 10 more stable. The casters 10 are evenly distributed, ensuring the stability and balance of the LED display device during movement. The omnidirectional rotation allows the device to be easily moved and adjusted in different directions, greatly improving the ease of use.
