[0036] like Figure 1 , Figure 12 as well as Figure 15As shown, the LED display device of this embodiment includes: a spherical support frame 10, an outer spherical screen structure 20, and an inner spherical screen structure 30. The spherical support frame 10 has an inner spherical surface located inside the spherical support frame 10 and an outer spherical surface located outside the spherical support frame 10. A plurality of annular maintenance channels 11 are also provided inside the spherical support frame 10, located between the inner and outer spherical surfaces, and the plurality of annular maintenance channels 11 are spaced apart in the height direction of the spherical support frame 10. The outer spherical screen structure 20 is disposed on the spherical support frame 10 and located at the outer spherical surface. The inner spherical screen structure 30 is disposed on the spherical support frame 10 and located at the inner spherical surface.

[0037] The spherical LED display device, using the technical solution of this embodiment, includes a spherical support frame 10, an outer spherical screen structure 20, and an inner spherical screen structure 30. Through the annular maintenance channel 11, the outer spherical screen structure 20 and the inner spherical screen structure 30 can be installed onto the spherical support frame 10, and maintenance of both structures can also be achieved. Therefore, the technical solution of this embodiment effectively solves the problem of limited display function in related technologies for spherical LED display devices.

[0038] It should be noted that the spherical support frame 10 is provided with multiple annular maintenance channels 11. The "inside the spherical support frame 10" refers to the space between the inner and outer spherical surfaces of the spherical support frame 10, and not the space enclosed by the side of the inner spherical surface away from the outer spherical surface.

[0039] like Figure 1 and Figure 2 As shown, in this embodiment, the spherical support frame 10 includes multiple latitude support structures 12 and at least one first longitude support structure 13. The multiple latitude support structures 12 are spaced apart in the height direction of the spherical support frame 10, and the at least one first longitude support structure 13 connects the multiple latitude support structures 12 together. An annular maintenance channel 11 is provided between two adjacent latitude support structures 12. The multiple latitude support structures 12 can be connected through the first longitude support structure 13. The annular maintenance channel 11 provided between two adjacent latitude support structures 12 facilitates the movement of operators between adjacent latitude support structures 12.

[0040] like Figures 3 to 5As shown, in this embodiment, the first meridian support structure 13 includes at least one first meridian support frame 131, and the two adjacent parallel support structures 12 include a first parallel support structure 1201 and a second parallel support structure 1202. The first parallel support structure 1201 is higher than the second parallel support structure 1202. The first meridian support frame 131 cooperates with the first parallel support structure 1201 and the second parallel support structure 1202. The first meridian support frame 131 is provided with an assembly opening 1311, and the first parallel support structure 1201 passes through the assembly opening 1311. The top of the assembly opening 1311 rests on the top of the first parallel support structure 1201, and the bottom of the first meridian support frame 131 is located above the second parallel support structure 1202. The first parallel support structure 1201 and the second parallel support structure 1202 can be connected through the first meridian support frame 131. The top of the assembly port 1311 is placed on top of the first latitude support structure 1201, that is, part of the structure of the first longitude support frame 131 is placed on top of the first latitude support structure 1201, which facilitates the connection between the first longitude support frame 131 and the first latitude support structure 1201.

[0041] It should be noted that the first meridian support frame 131 and the first parallel support structure 1201 are connected by bolts and nuts, or they can be connected by welding.

[0042] like Figures 3 to 5As shown, in this embodiment, two adjacent first warp support frames 131 include a first first warp support frame 13101 and a second first warp support frame 13102. The first first warp support frame 13101 is located above the second first warp support frame 13102, and the bottom of the first first warp support frame 13101 is disposed at the top of the second first warp support frame 13102. The second latitude support structure 1202 passes through the assembly opening 1311 of the second first warp support frame 13102, and the top of the assembly opening 1311 of the second first warp support frame 13102 rests on the top of the second latitude support structure 1202. The second latitude support structure 1202 passes through the assembly opening 1311 of the second first warp support frame 13102, that is, a portion of the structure of the second first warp support frame 13102 rests on the top of the second latitude support structure, which facilitates the connection between the second first warp support frame 13102 and the second latitude support structure. The bottom of the first first meridian support frame 13101 is connected to the top of the second first meridian support frame 13102, which facilitates the connection between the first first meridian support frame 13101 and the second first meridian support frame 13102. That is, by providing the assembly port 1311 and connecting the bottom of the first first meridian support frame 13101 to the top of the second first meridian support frame 13102, the connection between the first first meridian support frame 13101, the second first meridian support frame 13102, the first parallel support structure 1201, and the second parallel support structure 1202 can be achieved.

[0043] It should be noted that the first meridian support frame 13101, the second meridian support frame 13102, and the second parallel support structure 1202 are connected by bolts and nuts, or they can be connected by welding.

[0044] like Figure 3 and Figure 4 As shown, in this embodiment, the weft support structure 12 includes multiple weft support frames 121 connected in sequence, and a first warp support structure 13 is connected to the middle position of the weft support frames 121. The multiple sequentially connected weft support frames 121 facilitate the formation of the weft support structure 12. The first warp support structure 13 is connected to the middle position of the weft support frames 121, facilitating the connection between the first warp support structure 13 and the weft support frames 121.

[0045] It should be noted that there are multiple first meridian support structures 13. These multiple first meridian support structures 13 are spaced apart in the circumferential direction of the spherical support frame 10. Each latitude support frame 121 in a latitude support structure 12 is correspondingly arranged with a first meridian support frame 131. The top of the lowest first meridian support frame 131 in a first meridian support structure 13 is higher than the top of the lowest latitude support structure 12, and the bottom is lower than the bottom of the lowest latitude support structure 12. The multiple latitude support frames 121 are connected sequentially in the circumferential direction of the spherical support frame 10.

[0046] like Figure 1 , Figure 2 , Figure 6 as well as Figure 7 As shown, in this embodiment, the spherical support frame 10 further includes at least one second meridian support structure 14, which connects all the parallel support structures 12 located above the first meridian support structure 13. By setting the second meridian support structure 14, all the parallel support structures 12 located above the first meridian support structure 13 can be connected. This also avoids the situation where, when the first meridian support structure 13 is connected to all the parallel support structures 12, the first meridian support structure 13 divides each annular maintenance channel 11 located above the first meridian support structure 13 into smaller maintenance sub-channels, resulting in less space for operators to move around in the maintenance sub-channels, which is inconvenient for operators.

[0047] It should be noted that each second meridian support structure 14 is provided in correspondence with one first meridian support structure 13. The number of second meridian support structures 14 is less than the number of first meridian support structures 13.

[0048] like Figures 6 to 9As shown, in this embodiment, the three highest latitude support structures 12 among the plurality of latitude support structures 12 include a first top latitude support structure 1203, a second top latitude support structure 1204, and a third top latitude support structure 1205. The second top latitude support structure 1204 is located below the first top latitude support structure 1203, and the third top latitude support structure 1205 is located below the second top latitude support structure 1204. The second longitude support structure 14 is connected to the first top latitude support structure 1203, the second top latitude support structure 1204, and the third top latitude support structure 1205. The spherical support frame also includes at least one third longitude support structure 15, which includes a second longitude support frame 151 connected between the third top latitude support structure 1205 and the second top latitude support structure 1204. The second meridian support structure 14 connects the first top latitude support structure 1203, the second top latitude support structure 1204, and the third top latitude support structure 1205, thereby connecting all latitude support structures 12 under the action of the first meridian support structure 13 and the second meridian support structure 14. The third meridian support structure 15 connects the third top latitude support structure 1205 and the second top latitude support structure 1204, and avoids the situation where multiple third meridian support structures 15 divide each annular maintenance channel above the first meridian support structure 13 into smaller maintenance sub-channels, resulting in less space for operators within the maintenance sub-channels and hindering their movement.

[0049] It should be noted that the third top latitude support structure 1205 passes through the assembly port 1311 of the highest first meridian support frame 131 of the first meridian support structure 13. It should also be noted that if multiple second meridian support structures 14 are provided, especially when the number of second meridian support structures 14 is similar to the number of first meridian support structures 13, the second meridian support structures 14 will divide each annular maintenance channel 11 above the third top latitude support structure 1205 into smaller maintenance sub-channels, resulting in less space for operators to move within the maintenance sub-channels. Similarly, if multiple third meridian support structures 15 are provided, especially when the number of third meridian support structures 15 is similar to the number of first meridian support structures 13, the third meridian support structures 15 will divide the annular maintenance channel 11 between the third top latitude support structure 1205 and the second top latitude support structure 1204 into smaller maintenance sub-channels, further reducing the space for operators to move within the maintenance sub-channels and hindering their movement. It should be noted that the second meridian support frame 151 is provided with a first mounting opening 1511, and the second top weft support structure 1204 passes through the first mounting opening 1511. The top of the first mounting opening 1511 rests on the top of the second top weft support structure 1204, and the bottom of the second meridian support frame 151 is positioned above the third top weft support structure 1205. Specifically, the bottom of the second meridian support frame 151 is positioned on top of the first meridian support structure 13.

[0050] The second meridian support structure 14 includes a third meridian support frame 141 and a fourth meridian support frame 142. The third meridian support frame 141 is provided with a second mounting opening 1411. A second top weft support structure 1204 passes through the second mounting opening 1411, and the top of the second mounting opening 1411 is placed on top of the second top weft support structure 1204. The bottom of the third meridian support frame 141 is placed above the third top weft support structure 1205. The fourth meridian support frame 142 is provided with a third mounting opening 1421. A first top weft support structure 1203 passes through the third mounting opening 1421, and the top of the third mounting opening 1421 is placed on top of the first top weft support structure 1203. The bottom of the fourth meridian support frame 142 is placed above the second top weft support structure 1204. Specifically, the bottom of the third meridian support frame 141 is located on the top of the first meridian support structure 13, and the bottom of the fourth meridian support frame 142 is located on the top of the third meridian support frame 141.

[0051] It should be noted that each third meridian support structure 15 is correspondingly provided with one first meridian support structure 13, the number of first meridian support structures 13 is less than the number of first meridian support structures 13, and the sum of the number of second meridian support structures 14 and the number of third meridian support structures 15 is less than the number of first meridian support structures 13. It should also be noted that in the circumferential direction of the spherical support frame 10, a third meridian support structure 15 is provided between the second meridian support structure 14 and the first meridian support structure 13. Furthermore, at least a portion of the latitude support structures 12 are provided with a first connecting opening 122 penetrating the thickness direction of the latitude support structure, and the first meridian support structure 13 is provided with a first auxiliary climbing part 132, which is correspondingly provided with the first connecting opening 122. Through the first connecting opening 122 and the first auxiliary climbing part 132, climbing upwards from the lowest latitude support structure 12 is possible. The first connecting opening 122 includes at least one, and the first auxiliary climbing part 132 includes multiple, with each first auxiliary climbing part 132 of a first meridian support structure 13 corresponding to a latitude support structure 12. Each first meridian support frame 131 is provided with one first auxiliary climbing part 132. In this embodiment, each latitude support frame 121 is provided with one first connecting opening 122. The first connecting openings 122 of two adjacent latitude support structures 12 are staggered; specifically, in the circumferential direction of the spherical support frame 10, the first connecting openings 122 of two adjacent latitude support structures 12 are located on both sides of the first meridian support structure 13.

[0052] It should be noted that the first top weft support structure 1203 and the second top weft support structure 1204 do not have the first connecting opening 122, while the remaining weft support structures 12 all have the first connecting opening 122. Because the diameters of the first top weft support structure 1203 and the second top weft support structure 1204 are smaller than the diameters of all the weft support structures 12 below the second top weft support structure 1204, and because the distances between the first top weft support structure 1203 and the outer spherical screen structure 20, as well as the distance between the second top weft support structure 1204 and the outer spherical screen structure 20, it is possible to climb to the second top weft support structure 1204 via the third top weft support structure 1205, and to climb to the first top weft support structure 1203 via the second top weft support structure 1204. When climbing from the third top latitude support structure 1205 to the second top latitude support structure 1204, the second meridian support structure 14 and / or the third meridian support structure 15 can be used. When climbing from the second top latitude support structure 1204 to the first top latitude support structure 1203, the third meridian support structure 15 can be used. The first meridian support frame 131 includes a first vertical bar 1312, a first horizontal bar 1313, a second vertical bar 1314, and a second horizontal bar 1315 connected in sequence, with the second horizontal bar 1315 connecting the second vertical bar 1314 and the first vertical bar 1312. This forms the first meridian support frame 131. The first horizontal bar 1313 is erected on top of the first latitude support structure 1201. This facilitates the arrangement of the positions of the first meridian support frame 131 and the first latitude support structure 1201. The surface of the first vertical bar 1312 away from the second vertical bar 1314 is part of the outer spherical surface. The surface of the second vertical bar 1314 away from the first vertical bar 1312 is part of an inner spherical surface. The first meridian support frame 131 also includes a first reinforcing bar, which connects the intersection of the first vertical bar 1312 and the first horizontal bar 1313 and the intersection of the second vertical bar 1314 and the second horizontal bar 1315. This improves the structural strength of the first meridian support frame 131. The first auxiliary climbing part 132 includes a plurality of climbing poles spaced apart in the height direction of the spherical support frame 10, with both ends of the climbing poles connected to the second vertical bar 1314 and the first reinforcing bar, respectively. The tallest climbing pole in a first auxiliary climbing part 132 forms a mounting opening 1311 with the first horizontal bar 1313.

[0053] The second meridian support frame 151 includes a third vertical rod, a first diagonal rod, a fourth vertical rod, and a third horizontal rod connected in sequence. The third horizontal rod connects the fourth vertical rod and the third vertical rod, and is located at the top of the first meridian support structure 13. The surface of the third vertical rod away from the fourth vertical rod is part of an outer spherical surface. The surface of the fourth vertical rod away from the third vertical rod is part of an inner spherical surface. The second meridian support frame 151 also includes a second reinforcing rod and a third reinforcing rod. The second reinforcing rod connects the intersection of the first diagonal rod and the fourth vertical rod with the first vertical rod, and the third reinforcing rod connects the intersection of the fourth vertical rod and the third horizontal rod with the first vertical rod. The second and third reinforcing rods are arranged intersectingly, forming a first mounting opening 1511 between the second reinforcing rod, the third reinforcing rod, and the fourth vertical rod.

[0054] The third meridian support frame 141 has the same structure as the second meridian support frame 151. The fourth meridian support frame 142 includes a fifth vertical rod, a second diagonal rod, a sixth vertical rod, and a third diagonal rod connected in sequence. The third diagonal rod connects the sixth vertical rod and the fifth vertical rod and is located at the top of the third meridian support frame. Specifically, the third diagonal rod is located on the first diagonal rod of the third meridian support frame 141. The surface of the fifth vertical rod away from the sixth vertical rod is part of the outer spherical surface. The surface of the sixth vertical rod away from the fifth vertical rod is part of the inner spherical surface. The fourth meridian support frame 142 also includes a fourth reinforcing rod and a fifth reinforcing rod. The fourth reinforcing rod connects the intersection of the third diagonal rod and the sixth vertical rod and the fifth vertical rod. The fifth reinforcing rod connects the fourth reinforcing rod and the sixth vertical rod. The fourth reinforcing rod, the fifth reinforcing rod, and the sixth vertical rod form a third mounting opening 1421. The fifth reinforcing rod is mounted on top of the first top weft support structure 1203.

[0055] It should be noted that the vertical rods in the first, second, third, fourth, fifth, and sixth vertical rods extend along the meridian direction, not in a vertical direction. Specifically, the sides of all first meridian support frames 131, all second meridian support frames 151, all third meridian support frames 141, and all fourth meridian support frames 142 closest to the interior of the spherical support frame 10 are located on the same spherical surface, which is the inner spherical surface. The sides of all first meridian support frames 131, all second meridian support frames 151, all third meridian support frames 141, and all fourth meridian support frames 142 closest to the exterior of the spherical support frame 10 are located on the same spherical surface, which is the outer spherical surface.

[0056] like Figure 1 , Figure 2 as well as Figure 14As shown, in this embodiment, the spherical support frame 10 is spherical, with a height greater than its radius. An opening 16 is provided at the bottom of the spherical support frame 10, communicating with its interior. The greater height of the spherical support frame 10 allows for the placement of more inner spherical screen structures 30 and outer spherical screen structures 20, resulting in a larger display area for the spherical LED display device. The opening 16 allows access to the interior of the spherical support frame 10, facilitating viewing of the content displayed on the inner spherical screen structures 30. Access via the bottom avoids the need for an opening 16 on the side of the spherical support frame 10, which could lead to missing display areas.

[0057] It should be noted that the opening 16 is connected to the interior of the spherical support frame 10. The interior of the spherical support frame 10 refers to the space enclosed by the side of the inner spherical surface of the spherical support frame 10 away from the outer spherical surface. The height direction of the spherical support frame 10 is from the ground to the air.

[0058] like Figure 1 and Figure 18 As shown, in this embodiment, the spherical LED display device further includes a base 40, a spherical support frame 10 disposed on the top of the base 40, and an entrance / exit 41 provided on the side of the base 40, which communicates with the opening 16. The base 40 can support the spherical support frame 10, facilitating the assembly of the spherical LED display device. Through the entrance / exit 41, one can enter the opening 16, and then enter the interior of the spherical support frame 10 through the opening 16.

[0059] It should be noted that the multiple annular maintenance channels 11 include a bottom annular maintenance channel, a top annular maintenance channel, and at least one middle annular maintenance channel. The bottom annular maintenance channel is formed between the base 40 and the lowest weft support structure 12. The top annular maintenance channel is formed between the top of the highest weft support structure 12 and the outer spherical screen structure 20. The remaining annular maintenance channels other than the bottom and top annular maintenance channels are middle annular maintenance channels. An annular maintenance channel 11 is provided between two adjacent weft support structures 12; this annular maintenance channel 11 is the middle annular maintenance channel. When there are two weft support structures 12, there is one middle annular maintenance channel. When there are at least three weft support structures 12, there are at least two middle annular maintenance channels.

[0060] like Figure 1 , Figure 18 as well as Figure 19As shown, in this embodiment, a clearance space is provided in the middle of the base 40. The spherical LED display device also includes a central support 50 and a staircase structure 60. Both the central support 50 and the staircase structure 60 are located within the clearance space. The top surface of the central support 50 is the viewing surface. The staircase structure 60 is located between the central support 50 and the side wall of the clearance space, and connects the entrance 41 and the opening 16. The top surface of the central support 50 is the viewing surface, meaning that the top surface of the central support 50 can support the audience, facilitating their viewing of the content displayed on the inner spherical screen structure 30. The audience can walk through the entrance 41 to the staircase structure 60, and then walk through the staircase structure 60 to the top surface of the central support 50, i.e., to the viewing surface. The staircase structure 60 is positioned between the central support 50 and the side wall of the clearance space, which allows the central support 50 to have a larger external size, thus allowing for a larger viewing area and accommodating more viewers. It also facilitates the arrangement of the staircase structure 60, the central support 50, and the base 40.

[0061] like Figure 18 and Figure 19 As shown, in this embodiment, the central support base 50 includes a first vertical support frame 51, a second vertical support frame 52, and a first fan-shaped support assembly 53. The first vertical support frame 51, the second vertical support frame 52, and the first fan-shaped support assembly 53 are all disposed within a clearance space. The first vertical support frame 51, the second vertical support frame 52, and the stair structure 60 are sequentially arranged in the direction from the clearance space to the outside of the base 40. The two ends of the first fan-shaped support assembly 53 are respectively disposed on the first vertical support frame 51 and the second vertical support frame 52. The side of the first fan-shaped support assembly 53 closest to the clearance space is flush with the side of the second vertical support frame 52 closest to the clearance space. The stair structure 60 is located between the second vertical support frame 52 and the side wall of the clearance space. The top of the stair structure 60 communicates with the top of the first fan-shaped support assembly 53, and the top of the first fan-shaped support assembly 53 forms at least a partial viewing surface. The first vertical support frame 51 and the second vertical support frame 52 can support the first fan-shaped support assembly 53. The first vertical support frame 51, the second vertical support frame 52, and the staircase structure 60 are arranged sequentially in the direction from the clearance space to the outside of the base 40, which facilitates the installation of the first vertical support frame 51, the second vertical support frame 52, the staircase structure 60, and the base 40. The top of the staircase structure 60 is connected to the top of the first sector-shaped support component 53, which facilitates the audience to walk to the top of the first sector-shaped support component 53 via the staircase structure 60, that is, facilitates the audience to walk to the viewing surface.

[0062] It should be noted that the first sector support component 53 includes a plurality of first sector frames arranged sequentially in the circumferential direction of the spherical support frame 10.

[0063] like Figure 18 and Figure 19 As shown, in this embodiment, the central support base 50 includes a first vertical support frame 51 and a second fan-shaped support assembly 54 disposed within the clearance space. The first end of the second fan-shaped support assembly 54 is disposed on the first vertical support frame 51, and the second end of the second fan-shaped support assembly 54 is connected to the inner wall of the base 40. The top of the second fan-shaped support assembly 54 forms at least a partial viewing surface. This arrangement allows the first vertical support frame 51 and the inner wall of the base 40 to support the second fan-shaped support assembly 54, and also allows the top of the second fan-shaped support assembly 54 to have a larger area, thereby resulting in a larger viewing surface area.

[0064] It should be noted that the second sector-shaped support component 54 includes multiple second sector-shaped frames arranged sequentially in the circumferential direction of the spherical support frame 10. The radius of the second sector-shaped frame is larger than the radius of the first sector-shaped frame. The staircase structure 60 includes two that are spaced apart. Both the first sector-shaped support component 53 and the second sector-shaped support component 54 include two that are spaced apart, and a second sector-shaped support component 54 is arranged between two first sector-shaped support components 53 in the circumferential direction of the spherical support frame 10.

[0065] The base 40 is filled with concrete. The base 40 includes a third vertical support frame 42 and a fourth vertical support frame 43, which are arranged adjacent to each other. The adjacent third vertical support frames 42 and fourth vertical support frames 43 form a support frame group, and multiple support frame groups are spaced apart. An entrance 41 is formed between two support frame groups adjacent to the bottom of a staircase structure 60. The base 40 has a second auxiliary climbing section and a second connecting opening. The second auxiliary climbing section allows access to the second connecting opening, and then through the second connecting opening, to the area between the top of the base 40 and the lowest latitude support structure 12, i.e., access to the bottom annular maintenance passage. The third vertical support frame 42 and / or the fourth vertical support frame 43 are provided with the second connecting opening and the second auxiliary climbing section. The third vertical support frame 42 and / or the fourth vertical support frame 43 are formed by welding multiple steel pipes. The base 40 also includes multiple fan-shaped ring support frames 44 disposed on the third vertical support frame 42 and the fourth vertical support frame 43. These multiple fan-shaped ring support frames 44 are sequentially arranged in the circumferential direction of the spherical support frame 10, forming a ring structure. The bottom of the spherical support frame 10 is located at the top of the multiple fan-shaped ring support frames 44. That is, the fan-shaped ring support frames 44 can support the spherical support frame 10. The third vertical support frame 42 includes a main frame and a reinforcing frame disposed in the middle of the main frame. The reinforcing frame extends along the height direction of the spherical support frame, and its structure is similar to that of the first meridian support frame. The main frame has a fan-shaped ring structure.

[0066] like Figures 12 to 15As shown, in this embodiment, the inner spherical screen structure 30 includes multiple inner spherical LED display boxes 31. Each inner spherical LED display box 31 includes an inner spherical display box frame 311 connected to the spherical support frame 10 and an inner spherical LED display module 312 disposed on the side of the inner spherical display box frame 311 facing away from the spherical support frame 10. The spherical LED display device also includes multiple first adjustable connection components 70 and multiple second adjustable connection components 80. Multiple first adjustable connection components 70 are disposed on each latitude support structure 12. Two inner spherical display box frames 311 adjacent to a first adjustable connection component 70 are connected to the first adjustable connection component 70. Multiple second adjustable connection components 80 are disposed on each first longitude support structure 13. Two inner spherical display box frames 311 adjacent to a second adjustable connection component 80 are connected to the second adjustable connection component 80. The inner spherical display box frame 311 can support the inner spherical LED display module 312. A first adjustable connecting component 70 is provided to facilitate the connection of two adjacent inner spherical display cabinet frames 311 to the latitude support structure 12 via the first adjustable connecting component 70. A second adjustable connecting component 80 is provided to facilitate the connection of two adjacent inner spherical display cabinet frames 311 to the first longitude support structure 13 via the second adjustable connecting component 80. That is, by providing multiple first adjustable connecting components 70 and multiple second adjustable connecting components 80, the connection between the inner spherical screen structure 30 and the spherical support frame 10 can be realized, and the connection between the inner spherical screen structure 30 and the spherical support frame 10 can be made more stable.

[0067] It should be noted that the two inner spherical display cabinet frames 311 adjacent to the first adjustable connecting component 70 refer to the two inner spherical display cabinet frames 311 that are the closest to the first adjustable connecting component 70 among the plurality of inner spherical display cabinet frames 311. The same applies to the second adjustable connecting component 80. Each latitude support frame 121 is provided with one or more first adjustable connecting components 70. Each first longitude support frame 131, second longitude support frame 151, third longitude support frame 141, and fourth longitude support frame 142 is provided with at least one second adjustable connecting component 80. It should be noted that the number of first adjustable connecting components 70 and the number of inner spherical display cabinet frames 311 are not necessarily equal, and the number of second adjustable connecting components 80 and the number of inner spherical display cabinet frames 311 are not necessarily equal.

[0068] The inner spherical LED display cabinet frame 311 includes a hyperbolic panel, a main frame, and a reinforcing rib assembly. The hyperbolic panel has a first mounting surface and a second mounting surface arranged opposite to each other. The first mounting surface is used to mount the inner spherical LED display module 312. The main frame is disposed on the second mounting surface and includes two transverse support structures and multiple longitudinal support structures. The two transverse support structures are spaced apart along the length of the hyperbolic panel; the multiple longitudinal support structures are located between the two transverse support structures and spaced apart along the width of the hyperbolic panel, with each end of each longitudinal support structure connected to one of the two transverse support structures. The reinforcing rib assembly is disposed on the second mounting surface and within the main frame. The reinforcing rib assembly includes transverse reinforcing ribs and longitudinal reinforcing ribs. The transverse reinforcing ribs are located between the two transverse support structures and are connected to at least one longitudinal support structure; the longitudinal reinforcing ribs are located between two adjacent longitudinal support structures. The horizontal and vertical support structures form a stable main frame, effectively supporting the hyperbolic panel and ensuring its structural stability and shape retention during transportation and installation. This also simplifies the main frame structure, enabling a lightweight design. This achieves lightweight design while maintaining structural strength, solving the problems of difficult processing and weight constraints associated with lightweight designs in existing curved frames. Furthermore, the horizontal and vertical reinforcing ribs further enhance the internal structural strength of the main frame. The connection between the reinforcing rib components and the vertical support structure allows for precise control of the hyperbolic shape, preventing deformation caused by the weight of the inner spherical LED display module 312. Compared to traditional processing methods, the inner spherical display cabinet frame 311 in this embodiment not only reduces costs and improves production efficiency but also adapts to the needs of hyperbolic displays with different diameters and curvatures, enabling a wider range of applications.

[0069] The multiple longitudinal support structures include two first longitudinal support structures and at least one second longitudinal support structure located between the two first longitudinal support structures. The inner spherical display cabinet frame 311 also includes a first reinforcing corner plate. The first reinforcing corner plate is disposed at the connection between the transverse support structure and the first longitudinal support structure. By adding a first reinforcing corner plate at the critical connection point between the transverse support structure and the first longitudinal support structure, the stress at the connection point is effectively dispersed, avoiding problems such as loosening of the connection and structural deformation due to stress concentration during transportation, installation, or long-term use. Simultaneously, the above arrangement ensures that the inner spherical display cabinet frame 311 maintains good rigidity and shape stability when the hyperbolic panel bears the weight of the inner spherical LED display module 312, improving the overall performance and service life of the spherical LED display device.

[0070] Optionally, there is one first reinforcing corner plate; or, there are multiple first reinforcing corner plates, which are spaced apart along the length and / or width direction of the inner spherical display cabinet frame 311. In this embodiment, there are four first reinforcing corner plates, which are spaced apart along the length and width direction of the inner spherical display cabinet frame 311. At least one transverse support structure and / or at least one longitudinal support structure has multiple weight-reducing holes. This configuration, while ensuring the basic mechanical properties of the transverse and longitudinal support structures, achieves a lightweight design of the inner spherical display cabinet frame 311 by removing material from non-load-bearing parts to form weight-reducing holes.

[0071] Optionally, each lateral support structure is a first plate, the side of which is connected to the second mounting surface and its shape is adapted to the second mounting surface; and / or, each longitudinal support structure is a second plate, the side of which is connected to the second mounting surface and its shape is adapted to the second mounting surface. In this way, the first and second plates form a seamless connection through the precise adaptation of their sides to the second mounting surface of the hyperbolic panel. This not only significantly enhances the bonding strength between the support structure and the hyperbolic panel and reduces installation errors of the inner spherical LED display module 312 caused by connection gaps, but also effectively avoids local deformation of the inner spherical display cabinet frame 311 when subjected to external pressure or the weight of the inner spherical LED display module 312, improving the stability and reliability of the overall structure.

[0072] In this embodiment, each lateral support structure is a first plate, the side of which is connected to the second mounting surface and its shape is adapted to the second mounting surface. Each longitudinal support structure is a second plate, the side of which is connected to the second mounting surface and its shape is adapted to the second mounting surface. This achieves the purpose of improving the fit between the frame and the hyperbolic panel, enhancing the structural stability of the connection points, thereby realizing a tighter and more stable frame connection effect, ensuring the hyperbolic display screen maintains its shape and visual effect under various conditions.

[0073] The inner spherical display cabinet frame 311 also includes a traction structure. The first end of the traction structure is connected to at least one auxiliary transverse reinforcing rib, and the second end is used to connect to the inner spherical LED display module 312. By providing a traction structure in the inner spherical display cabinet frame 311, with its first end connected to at least one auxiliary transverse reinforcing rib and its second end directly connected to the inner spherical LED display module 312, the mechanical connection stability between the display module and the inner spherical display cabinet frame 311 is enhanced, improving the overall structural reliability. Even in the event of accidental impact or vibration, the inner spherical LED display module can still be firmly fixed to the inner spherical display cabinet frame 311, preventing it from falling off. In this embodiment, the auxiliary transverse reinforcing rib has a connecting hole, and the first end of the traction structure connects to the connecting hole, effectively reducing the risk of the inner spherical LED display module 312 falling due to magnetic failure during installation, thus ensuring construction safety.

[0074] Optionally, the direction from the first mounting surface to the second mounting surface is a preset direction, and the middle part of the first mounting surface protrudes along the preset direction; and / or, the hyperbolic panel is formed by stamping. In this way, by making the middle part of the first mounting surface of the hyperbolic panel protrude along the direction from the first mounting surface to the second mounting surface (i.e., the preset direction), and by using stamping to manufacture the hyperbolic panel, the purpose of enhancing the structural strength of the panel, optimizing the display effect, simplifying the inner spherical display cabinet frame 311, and controlling costs are achieved. This results in a lightweight, high-strength, and high-precision hyperbolic panel, providing a more stable and aesthetically pleasing display surface for the inner spherical LED display module 312.

[0075] In this embodiment, the direction from the first mounting surface to the second mounting surface is a preset direction, and the center of the first mounting surface protrudes along this preset direction. The hyperbolic panel is formed by stamping. This central protrusion design along the preset direction increases the rigidity of the hyperbolic panel in that direction, effectively preventing the panel from denting or deforming under stress, ensuring that the display maintains good display effects and structural safety even after long-term operation or external impact. Simultaneously, the stamping process enables efficient mass production of hyperbolic panels and ensures consistency in the geometric dimensions and shape of each panel component, improving manufacturing precision. Furthermore, the stamping process utilizes molds to shape the sheet material, precisely controlling the curvature and protrusion degree of the panel, avoiding errors that may occur during manual welding or cutting, reducing installation problems of the inner spherical LED display module 312 due to manufacturing inconsistencies, and ensuring the aesthetics and visual consistency of the spherical screen. Optionally, the inner spherical LED display module 312 is magnetically connected to the first mounting surface.

[0076] like Figure 2 as well as Figures 12 to 15As shown, in this embodiment, the first meridian support structure 13 includes multiple structures. In the circumferential direction of the spherical support frame 10, the plane containing each of two adjacent first meridian support structures 13 and the axis of the spherical support frame 10 enclose an installation area. Each inner spherical display cabinet frame 311 located within the installation area is an elevated cabinet frame 31101. The inner spherical display cabinet frame 311 adjacent to the elevated cabinet frame 31101 is an auxiliary connecting frame 31102. Multiple auxiliary connecting frames 31102 are included, and each elevated cabinet frame 31101 is connected to at least one of the multiple auxiliary connecting frames 31102 via fasteners. The elevated cabinet frame 31101 can be connected to the auxiliary connecting frame 31102 via fasteners, thus making the position of the elevated cabinet frame 31101 more stable. The elevated box frame 31101 is indirectly connected to the spherical support frame 10 through the auxiliary connecting frame 31102, which makes the position of the elevated box frame 31101 relative to the spherical support frame 10 more stable.

[0077] It should be noted that the two adjacent inner ball display box frames 311 are connected by bolts and nuts.

[0078] like Figure 1 , Figure 10 , Figure 11 , Figure 16 as well as Figure 17As shown, in this embodiment, the outer spherical screen structure 20 includes multiple outer spherical LED display boxes 21. Each outer spherical LED display box 21 includes an outer spherical display box frame 211 connected to the spherical support frame 10 and an outer spherical LED display module 212 disposed on the side of the outer spherical display box frame 211 facing away from the spherical support frame 10. The spherical LED display device also includes multiple third adjustable connection components 90 and multiple fourth adjustable connection components 100. Multiple third adjustable connection components 90 are disposed on each latitude support structure 12. Two outer spherical display box frames 211 adjacent to a third adjustable connection component 90 are connected to that third adjustable connection component 90. Multiple fourth adjustable connection components 100 are disposed on each first longitude support structure 13. Two outer spherical display box frames 211 adjacent to a fourth adjustable connection component 100 are connected to that fourth adjustable connection component 100. The outer spherical display box frame 211 can support the outer spherical LED display module 212. A third adjustable connecting component 90 is provided to facilitate the connection of two adjacent outer spherical display cabinet frames 211 to the latitude support structure 12 via the third adjustable connecting component 90. A fourth adjustable connecting component 100 is provided to facilitate the connection of two adjacent outer spherical display cabinet frames 211 to the first longitude support structure 13 via the fourth adjustable connecting component 100. That is, by providing multiple third adjustable connecting components 90 and multiple fourth adjustable connecting components 100, the connection between the outer spherical screen structure 20 and the spherical support frame 10 can be realized, and the connection between the outer spherical screen structure 20 and the spherical support frame 10 can be made more stable.

[0079] It should be noted that the two outer spherical display cabinet frames 211 adjacent to a third adjustable connecting component 90 refer to the two outer spherical display cabinet frames 211 that are the closest to the third adjustable connecting component 90 among the plurality of outer spherical display cabinet frames 211. The same applies to the fourth adjustable connecting component 100. Multiple fourth adjustable connecting components 100 are provided on each first meridian support frame 131. Multiple third adjustable connecting components 90 are provided on each parallel support frame 121.

[0080] It should be noted that the number of the third adjustable connecting components 90 is not necessarily equal to the number of the outer spherical display cabinet frames 211, and the number of the fourth adjustable connecting components 100 is not necessarily equal to the number of the outer spherical display cabinet frames 211. It should also be noted that adjacent outer spherical display cabinet frames 211 are connected by bolts and nuts.

[0081] The outer spherical display cabinet frame 211 of this embodiment includes: an outer frame, a display screen mounting bracket, and a first reinforcing structure. The display screen mounting bracket is disposed on the outer frame and has a third mounting surface. The first reinforcing structure includes a plurality of reinforcing components spaced apart, each reinforcing component including a plurality of first reinforcing plates spaced apart, both ends of each first reinforcing plate being connected to the inner wall of the outer frame. The distance between two adjacent reinforcing components is a first distance, and the distance between two adjacent first reinforcing plates is a second distance, the first distance being greater than the second distance. The outer frame can support the display screen mounting bracket, and the outer spherical LED display module 212 is disposed at the third mounting surface. The use of reinforcing components with multiple first reinforcing plates improves the structural strength of the outer spherical display cabinet frame 211. Limiting the relationship between the first and second distances improves the structural strength of the portion of the outer spherical display cabinet frame 211 located at the reinforcing components, further increasing the structural strength of the outer spherical display cabinet frame 211 and preventing plastic deformation of the outer spherical display cabinet frame 211 during transportation and use.

[0082] It should be noted that, in the height direction of the outer frame, the minimum distance between two adjacent reinforcing components is the first distance, and the minimum distance between two adjacent first reinforcing plates is the second distance. Specifically, the outer frame includes a first mounting plate, a second mounting plate, a third mounting plate, and a fourth mounting plate connected in sequence, with both ends of the fourth mounting plate connected to the first and third mounting plates, respectively. The direction from the first mounting plate to the third mounting plate is the height direction of the outer frame. Both ends of the first reinforcing plate are connected to the second and fourth mounting plates, respectively. The first, second, third, and fourth mounting plates can be laser-cut and then welded. The outer frame also includes second reinforcing corner plates, which are provided at the connection points of the first and second mounting plates, the second and third mounting plates, the third and fourth mounting plates, and the first and fourth mounting plates. Each reinforcing component is connected to the surface of the display mounting bracket facing away from the third mounting surface. Through the above arrangement, the display mounting bracket has stronger resistance to deformation, thereby improving the overall structural strength of the outer spherical display cabinet frame 211. Multiple reinforcing components are spaced apart in the height direction of the outer frame. The above configuration improves the overall structural strength of the outer spherical display box frame 211 in the height direction of the outer frame. It should be noted that multiple reinforcing components are arranged in parallel.

[0083] Multiple first reinforcing plates of a reinforcing component are spaced apart along the height of the outer frame. Through this arrangement, each first reinforcing plate connects different positions of the outer frame, thereby strengthening the structure at different locations of the outer frame, resulting in better structural strength of the outer frame and consequently, better structural strength of the outer spherical display housing frame 211. It should be noted that in this embodiment, the multiple first reinforcing plates are arranged in parallel. In other embodiments, adjacent first reinforcing plates within a reinforcing component may be arranged at an angle. It should also be noted that the first reinforcing plate can be a flat plate or a curved plate.

[0084] The display mounting frame includes multiple spaced vertical plates and multiple spaced horizontal plates. The surface of each vertical plate facing away from the first reinforcing structure, and the surface of each horizontal plate facing away from the first reinforcing structure, form a third mounting surface, which is a partially spherical structure. The horizontal and vertical plates not only allow the outer spherical LED display module 212 to connect to the display mounting frame, but also make the display mounting frame lighter compared to a curved plate. It should be noted that the display mounting frame can be formed by laser cutting followed by stamping. The third mounting surface being a partially spherical structure means that the third mounting surface is a portion of a sphere. It should be noted that both ends of the vertical plates can be connected to the first and third mounting plates, or one end can be connected to the first mounting plate and the other end to the horizontal plate closest to the second mounting plate among the multiple horizontal plates. The two ends of the horizontal plates are connected to the second and fourth mounting plates, respectively. Specifically, the multiple horizontal plates are spaced apart along the height direction of the outer frame. The multiple vertical plates are spaced apart along the circumferential direction of the third mounting surface. Each horizontal plate corresponds to one of the multiple first reinforcing plates. The above-described arrangement enhances the deformation resistance of the horizontal plates, thereby strengthening the structural strength of the outer spherical display housing frame 211. It should be noted that the number of horizontal plates is not necessarily equal to the number of the first reinforcing plates; in other embodiments, the number of horizontal plates is greater than the number of the first reinforcing plates.

[0085] The first reinforcing structure also includes at least one second reinforcing plate, each second reinforcing plate corresponding to one of the multiple vertical plates. The inclusion of second reinforcing plates enhances the deformation resistance of the outer frame, thereby increasing the structural strength of the outer spherical display cabinet frame 211. The corresponding arrangement of each second reinforcing plate with one of the multiple vertical plates further enhances the deformation resistance of the vertical plate, thus increasing the overall structural strength of the outer spherical display cabinet frame 211.

[0086] The two ends of the second reinforcing plate can be connected to the first mounting plate and the third mounting plate respectively, or one end can be connected to the first mounting plate and the other end can be left unconnected. One of the multiple second reinforcing plates has a larger overall size than all the others, thus improving the structural strength of the outer spherical display cabinet frame 211. Simultaneously, the HUB board of the LED display unit can be mounted to the adjacent location of this second reinforcing plate on the outer spherical display cabinet frame 211 via the bracket structure 22. The number of second reinforcing plates can differ from the number of vertical plates, with the number of vertical plates exceeding the number of second reinforcing plates. Each vertical plate and each horizontal plate has multiple mounting holes for mounting the outer spherical LED display module 212. The outer spherical LED display module 212 can be mounted to the horizontal and vertical plates through these mounting holes, thus connecting the outer spherical LED display module 212 to the outer spherical display cabinet frame 211.

[0087] It should be noted that there can be one or more outer spherical LED display modules 212, arranged in a fan-shaped structure, with adjacent modules fitted together. Each outer spherical LED display module 212 includes a circuit board and multiple LED light-emitting elements mounted on the board. The module also includes a waterproof structure to prevent moisture from contacting the circuit board and LED light-emitting elements, thus protecting their functionality. The LED light-emitting elements can be LED beads, specifically LED beads containing red, green, and blue light-emitting chips. Alternatively, the light-emitting elements can consist only of red, green, and blue light-emitting chips, all directly mounted on the circuit board without encapsulation.

[0088] The outer spherical LED display cabinet 21 also includes a flexible component 213 and a positioning component 214. The flexible component 213 is disposed on the side of the circuit board of the outer spherical LED display module 212 near the outer frame, and the outer spherical LED display module 212 is connected to the outer frame through the positioning component 214. The flexible component 213 is disposed between the outer spherical LED display module 212 and the outer frame. Multiple light-transmitting holes are formed on the circuit board of the outer spherical LED display module 212, all of which are arranged through the thickness direction of the circuit board, allowing light to pass through the holes from one side of the outer spherical LED display module 212 to the other side. By forming multiple light-transmitting holes through the thickness direction on the outer spherical LED display module 212, the outer spherical LED display cabinet 21 effectively solves the problem of inconvenient internal lighting of outdoor spherical displays in the prior art, allowing natural light to enter the display, improving the installation and maintenance environment, eliminating the need for additional lighting equipment, and saving power resources. Meanwhile, the design of the light-transmitting holes reduces the weight of the outer spherical LED display module 212. The placement of these holes also facilitates the deformation of the outer spherical LED display module 212, resulting in a smoother splicing effect for subsequent display modules, thus improving the display quality and preventing corrugations at the splicing points, thereby enhancing the viewing experience. Specifically, multiple light-transmitting holes are located on the circuit board. In particular, the light-transmitting holes located on the sides of the circuit board are semi-circular holes, not full-circular holes. This allows the two corresponding semi-circular holes on adjacent circuit boards to form a full-circular hole after splicing. This prevents the appearance of a black area at the splicing point of two outer spherical LED display modules, which would occur without semi-circular holes, thus avoiding a deterioration in the display quality of the outer spherical screen structure. In short, without sacrificing display performance, the light transmittance, weight reduction, and splicing effect of the outdoor spherical display screen are significantly improved. The flexible component is disposed between the circuit board and the outer frame of the outer spherical LED display module 212. Since the side of the outer frame away from the spherical support frame in this embodiment is curved, the flexible component is disposed thereto. The flexible component can deform, which makes it easy for the gap between the circuit board and the outer frame to be filled by the flexible component. This avoids the gap between the circuit board and the outer frame, which would cause moisture to enter the outer frame from the gap between the circuit board and the outer frame.

[0089] The outer spherical LED display module 212 has a waterproof layer on the side away from the outer frame. This waterproof layer is made of a transparent material and covers the side of the circuit board away from the outer frame and the LED light-emitting elements. Preferably, the waterproof layer is formed by the curing of adhesive. In this embodiment, the outer spherical LED display module 212 adopts a unique structural design, in which waterproof layers are provided on the upper and lower surfaces and inside the light-transmitting holes. This waterproof layer is made of a transparent material, ensuring the waterproof performance of the outer spherical LED display module 212 without hindering light transmission. This design achieves the waterproof function of the outdoor display screen while maintaining its light transmittance, especially under sunlight, illuminating the internal space of the screen, improving the working environment, and reducing the need for additional lighting. The addition of the transparent waterproof layer not only enhances the overall waterproof effect of the display module but also optimizes the module's manufacturing process. During GOB potting waterproofing treatment of the module, the adhesive adheres tightly to the outer spherical LED display module 212, ensuring the durability and reliability of the outer spherical LED display module 212 in outdoor environments. In addition, the waterproof layer can effectively reduce the impact of external factors such as rain and dust on the internal circuitry of the module.

[0090] like Figures 21 to 23 As shown, the flexible component 213 includes a support component 2131 and a flexible pad 2132. The flexible pad is disposed on the side of the support component away from the outer spherical LED display module 212. Both the flexible pad and the support component have first clearance through holes, through which the positioning component passes and connects to the outer frame. The hardness of the support component is greater than that of the flexible pad. It should be noted that the support component includes a support strip, which is made of stainless steel. The support strip has a hollow rectangular structure. The difference between the flexible pad and the support strip is that the hollow portion of the flexible pad has two connecting pads extending along the width direction of the flexible pad at intervals.

[0091] A waterproof layer may also be provided between the support member and the outer spherical LED display module 212. At least part of the positioning member is located between the support member and the outer spherical LED display module 212. The waterproof layer is formed by curing adhesive and can prevent moisture from entering the outer frame through the gap between the support member and the circuit board of the outer spherical LED display module 212.

[0092] In this embodiment, one end of the positioning member is connected to the side of the circuit board near the flexible component. The other end of the positioning member passes through the first clearance through-hole on the support member, the first clearance through-hole on the flexible pad, and the mounting hole on the outer frame in sequence, and is then connected to the outer frame via the locking member 215. The locking member is a screw. Under the action of the positioning member and the locking member, the outer spherical LED display module 212 can be installed onto the outer frame. Furthermore, due to the support member, the support member and the positioning member can share the pulling force of the locking member, avoiding the problem that the positioning member is easily pulled off the circuit board by the locking member when the support member is not provided. Specifically, the positioning member is made of copper and is welded to a copper ring on the surface of the circuit board near the outer frame. The side of the circuit board near the outer frame is the IC surface. In this embodiment, the positioning member has a locking hole inside, which faces the outer frame; the outer frame has a mounting hole, and the locking member passes through the mounting hole and locks into the locking hole. The flexible pad is made of silicone material. Furthermore, in this embodiment, the thickness of the outer spherical LED display module 212 is less than 10 mm. This design reduces the overall thickness of the display module, thereby reducing its weight.

[0093] It should be noted that the inner spherical LED display module 312 differs from the outer spherical LED display module 212 in that the inner spherical LED display module 312 does not have a copper ring on its circuit board, nor is it connected to the outer spherical display cabinet frame via positioning or locking components. Instead, the inner spherical LED display module 312 is magnetically connected to the outer spherical display cabinet frame.

[0094] The first adjustable connecting component 70, the second adjustable connecting component 80, the third adjustable connecting component 90, and the fourth adjustable connecting component 100 are all connecting structures. Each connecting structure includes: a first adapter, which is mounted on the outer spherical display cabinet frame; a second adapter, one end of which is connected to the first adapter; and a third adapter, which is mounted on the warp support structure or maintenance support structure of the spherical support frame, and the other end of which is connected to the second adapter. The connecting structure has a pre-assembly state and an assembled state. When the connecting structure is in the pre-assembly state, the second adapter is rotatably connected to both the first and third adapters. When the connecting structure is in the assembled state, the second adapter is securely connected to both the first and third adapters. The connecting structure of the spherical LED display device includes the first adapter, the second adapter, and the third adapter. In the pre-assembled state, the second adapter is rotatably connected to the first and third adapters, allowing for free angle adjustments during installation. This effectively accommodates the large area and high curvature of the outer spherical display cabinet frame, avoiding display screen height discrepancies caused by insufficient steel structure installation precision. Once the second adapter is positioned optimally according to installation requirements, its rotational freedom is restricted by a fastening connection, entering the assembly state and ensuring the stability of the outer spherical display cabinet frame and the consistency of display effects. This connection structure not only reduces reliance on steel structure precision but also minimizes display errors caused by improper installation.

[0095] Specifically, the first adapter has a first pre-installation hole and at least one first positioning hole. The first pre-installation hole is located at the end of the first adapter near the second adapter and is a strip-shaped hole. When the connecting structure is in a pre-assembled state, the first adapter is connected to the second adapter through the first pre-installation hole, and at least one first positioning hole is located around the first pre-installation hole. When the connecting structure is in an assembled state, the first adapter is connected to the second adapter through the first pre-installation hole and at least one first positioning hole. The third adapter has a second pre-installation hole and at least one second positioning hole. The second pre-installation hole is located at the end of the third adapter near the second adapter. When the connecting structure is in a pre-assembled state, the third adapter is connected to the second adapter through the second pre-installation hole, and at least one second positioning hole is located around the second pre-installation hole. When the connecting structure is in an assembled state, the third adapter is connected to the second adapter through the second pre-installation hole and at least one second positioning hole.

[0096] In the above embodiment, the first adapter is also provided with a second connecting hole, which is located on the side of the first adapter near the outer spherical display cabinet frame, and is used to pass through the adapter that connects to the outer spherical display cabinet frame.

[0097] In this embodiment, the first adapter is equipped with a first pre-installation hole and at least one first positioning hole. The first pre-installation hole is located near the end of the second adapter and is designed as a strip hole. During pre-assembly, the first adapter is initially connected to the second adapter through the first pre-installation hole, while the first positioning hole surrounds the first pre-installation hole. When entering the final assembly state, the first adapter forms a stable connection with the second adapter through the first pre-installation hole and at least one first positioning hole. Simultaneously, the third adapter is provided with a second pre-installation hole and at least one second positioning hole. The second pre-installation hole is also located near the end of the second adapter. During pre-assembly, the third adapter connects to the second adapter through the second pre-installation hole, and the second positioning hole is arranged around the second pre-installation hole. In the assembled state, the second pre-installation hole and at least one second positioning hole work together to ensure a firm connection between the third adapter and the second adapter. This design allows for quick alignment and initial fixation using the strip holes during the initial installation phase, followed by fixation via positioning holes and self-tapping screws. This restricts the rotational freedom of the adapters, reducing installation errors, minimizing the installation drop of the spherical display device, and improving assembly accuracy and display consistency. Furthermore, the combination of the first pre-installation hole and the first positioning hole, as well as the coordination of the second pre-installation hole and the second positioning hole, ensures stable assembly of the spherical screen without relying on the precision of the steel structure. This reduces the need for multiple adapters during installation, simplifies the installation process, and enhances assembly flexibility and efficiency.

[0098] Specifically, a first mounting surface is formed on the first adapter for connecting with the second adapter, a second mounting surface is formed on the second adapter for connecting with the first adapter and the third adapter, and a third mounting surface is formed on the third adapter for connecting with the second adapter. The planes containing the first, second, and third mounting surfaces are all arranged in parallel so that the second adapter can be rotatably connected with both the first and third adapters.

[0099] In this embodiment, a unique connection mechanism is formed between the first adapter, the second adapter, and the third adapter. Specifically, the first adapter has a first mounting surface, which is parallel to and opposite to the second mounting surface of the second adapter, allowing them to rotate freely within a certain range through an initial connection via an elongated hole. Similarly, the third mounting surface of the third adapter is also parallel to the second mounting surface of the second adapter, ensuring similar degrees of rotational freedom. The key to this parallel design is that it not only defines the relative positions between the adapters but also ensures that the contact points on the connecting surfaces can change during the adjustment of the display screen, thereby achieving precise positioning and installation. After the display screen is debugged, it is fixed with self-tapping screws in the reserved holes, effectively restricting the rotational freedom of the connecting components, reducing installation errors, and thus reducing the installation drop of the spherical display device. This achieves a smooth fit of the display screen, does not rely on the high precision of the steel structure, and simplifies the installation process and component requirements of the spherical screen.

[0100] Specifically, the third adapter includes a first connecting part and a second connecting part, which are set at a preset angle. The first connecting part is used to connect with the second adapter, and the second connecting part is used to connect with the spherical support frame. The first connecting part is located at the end of the second connecting part near the second adapter, and the first connecting part forms a third mounting surface.

[0101] An embodiment of a third adapter is provided, which is designed to include a first connecting portion and a second connecting portion, both set at a preset angle. The first connecting portion, near one end of the second adapter, forms a third mounting surface for connection with the second adapter, while the second connecting portion is connected to a spherical support frame. This structural design allows the adapter to form an adjustable connection between the spherical support frame and the display screen, thereby enabling fine-tuning of the display screen position during installation and ensuring the continuity and consistency of the spherical screen surface. The preset angle between the first and second connecting portions ensures that the connecting assembly can adapt to changes in the curvature of the spherical structure in different directions, improving installation flexibility and accuracy. By implementing rotational adjustment of the adapter on the first connecting portion, the display screen drop caused by steel structure installation errors can be effectively reduced, thereby optimizing the display effect. This eliminates reliance on high-precision steel structure installation, reduces the drop problem of the spherical screen, and also reduces the number of different types of adapters required for spherical screen installation, simplifying the installation process and improving efficiency.

[0102] In the above embodiment, the third adapter is used to connect with the first meridian support structure of the spherical support frame of the spherical display device, and the second connecting part is connected to the side of the first meridian support structure near the adapter. Specifically, at least part of the second connecting part is arranged perpendicular to the plane of the first connecting part, and the second connecting part is provided with a plurality of first connecting holes, through which the second connecting part is connected to the spherical support frame.

[0103] In this embodiment, at least a portion of the second connecting part is perpendicular to the plane of the first connecting part. This structural layout allows the adapter three to be securely fixed to the spherical support frame, enhancing the overall structural stability. The second connecting part is equipped with multiple first connecting holes, through which the second connecting part can form a multi-point fixation with the spherical support frame. This not only improves the reliability of the connection but also allows the adapter three to have a certain degree of freedom of position adjustment during initial installation, facilitating precise alignment. After adjustment, the tight connection between the first connecting holes and the spherical support frame restricts the movement freedom of the adapter three, ensuring accurate fixation of the display screen on the spherical steel frame. This reduces the display screen drop caused by steel structure installation errors, thereby improving the overall visual effect and installation adaptability of the spherical display device. Of course, in other embodiments not shown in the figures, the position and angle of the second connecting part can be flexibly adjusted according to actual application needs to adapt to different spherical steel frame structures. This design increases the versatility and adjustability of the connection structure, reducing the need for dedicated adapters when installing spherical displays.

[0104] Specifically, the second connecting portion includes a first connecting plate and at least one second connecting plate. The first connecting plate is arranged perpendicularly to the plane where the first connecting portion is located. At least one second connecting plate is arranged on the side of the first connecting plate away from the first connecting portion. Each second connecting plate extends in a direction away from the first connecting plate. At least one of a plurality of first connecting holes is provided on both the first and second connecting plates.

[0105] This embodiment provides another embodiment of the third adapter. The second connecting portion includes a first connecting plate and at least one second connecting plate. The first connecting plate is disposed perpendicular to the plane of the first connecting portion and located on the side away from the first connecting portion. At least one second connecting plate is distributed at the distal end of the first connecting plate, extending in a direction away from the first connecting plate, and both the first connecting plate and each second connecting plate are provided with at least one of a plurality of first connecting holes. This design provides multiple connection points through the multi-directional structure of the first and second connecting plates, enhancing the stability of the connection between the adapter and the spherical steel frame. At the same time, the provision of the first connecting holes allows the adapter to be flexibly adjusted according to the installation requirements of the spherical screen, ensuring precise alignment of the display screen during installation, thereby reducing the drop error caused by insufficient precision of the steel structure and improving the overall display effect of the spherical screen.

[0106] In the above embodiments, the third adapter is used to connect with the weft support structure of the spherical support frame of the spherical display device, and the first connecting plate and at least one second connecting plate are connected to the side of the wire mounting frame near the adapter.

[0107] Specifically, the third adapter also includes a reinforcing rib, which is connected to both the first connecting plate and the first connecting part. The plane of the reinforcing rib is perpendicular to both the plane of the first connecting plate and the plane of the first connecting part.

[0108] Specifically, the second adapter is provided with a plurality of first mounting holes, which are spaced apart along the extension direction of the second adapter. Each first mounting hole is a strip-shaped hole, and each strip-shaped hole extends along the extension direction of the second adapter.

[0109] In this embodiment, the second adapter has multiple first mounting holes. These holes are spaced apart along the extension direction of the second adapter and are designed as strip holes, with their extension direction consistent with the length direction of the second adapter. This structure allows the positions of adapter one and adapter three on the second adapter to be freely adjusted within a certain angle range, thereby enabling flexible assembly of the spherical screen in different installation environments. During the initial installation of the display screen, adapter one and adapter three only need to be initially connected to the second adapter through the elongated holes at both ends, without the need for precise alignment, which improves installation efficiency and reduces dependence on the precision of the steel structure. After the display screen is installed and adjusted to the ideal state, it is fixed to the second adapter by self-tapping screws reserved in the holes of adapter one and adapter three, thereby restricting the rotational freedom of the adapter and ensuring the stability and positional accuracy of the display screen.

[0110] In addition, the second adapter can be made into a longer structure, which can be cut to the required length as needed during actual use, making it easy to adapt to various working conditions and connection structures.

[0111] Specifically, the second adapter is provided with at least one set of second reinforcing structures, each set of second reinforcing structures includes two reinforcing members, the two reinforcing members are respectively provided on both sides of the second adapter along the width direction, each reinforcing member extends along the extension direction of the second adapter, and at least a portion of each reinforcing member extends in a direction away from the second adapter.

[0112] In this embodiment, the second adapter is provided with at least one set of second reinforcing structures, each set including two reinforcing members. These two reinforcing members are distributed on both sides of the second adapter in the width direction, arranged along its extension direction, and at least partially extending outward. This enhances the structural stability and load-bearing capacity of the second adapter, ensuring the safety and reliability of the adapter when bearing the weight of the display screen and external loads such as wind force.

[0113] In the installation process of the connection structure of the spherical LED display device in this embodiment, firstly, the first adapter is initially connected to one end of the second adapter through its first pre-installed hole. At this time, this is achieved only through an elongated hole, allowing the first adapter to rotate freely relative to the second adapter within a certain range. This adapts to the large area and high curvature characteristics of the outer spherical display cabinet frame and solves the problem caused by insufficient installation accuracy of the steel structure. Subsequently, the third adapter is similarly initially connected to the other end of the second adapter through the second pre-installed hole, also providing rotational freedom to fine-tune the position between the display screen and the spherical support frame. After determining the optimal position, the connection structure is adjusted from the pre-assembled state to the assembled state. Through the first and second positioning holes and self-tapping screws, the first and third adapters are firmly fixed to the second adapter, thereby restricting the rotational freedom of the second adapter, ensuring the stable installation of the outer spherical display cabinet frame on the spherical support frame, and reducing the drop error of the display screen.

[0114] Furthermore, the multiple first mounting holes on the second adapter provide initial connection freedom for the first and third adapters during the pre-assembly stage, allowing adjustment of the display screen's angle and position according to site conditions, ensuring ideal visual effects in any installation environment. Once the connection structure enters the assembly state, it is precisely fixed using the first and second positioning holes, restricting the second adapter's movement freedom, reducing installation errors, and minimizing the display screen's installation drop. Simultaneously, the first and second connecting parts of the third adapter are set at a preset angle. The second connecting part includes a first connecting plate and at least one second connecting plate. The multiple first connecting holes ensure multi-point connection with the spherical support frame, improving connection stability and precision.

[0115] like Figure 20 and Figure 21As shown, the outer spherical screen structure 20 also includes a support structure 22, which is mounted on the outer spherical display cabinet frame 211 and includes a base and a second base. The inner spherical screen structure 30 also includes the support structure 22. The base includes a first base and a second connecting structure connected to each other. The first base has a fourth mounting surface for mounting the power module 23, and the second connecting structure is used to connect to the outer spherical display cabinet frame. The second base has a fifth mounting surface for mounting the HUB board 24, and the first base is connected to the second base via the second connecting structure. The second connecting structure is located between the fourth and fifth mounting surfaces. The first mounting bracket is used to install the power module, and the second mounting bracket is used to install the HUB board. The two are connected by a second connecting structure, which not only achieves integrated installation of the power module and HUB board, optimizing space layout and simplifying the installation process, but also shortens the distance between the power module and HUB board, reducing cable length and making the wiring neater and more aesthetically pleasing. This solves the problem in existing technologies where the fixing method of the power module and HUB board increases the difficulty of disassembly and assembly and results in excessively long cable distances, thus improving the assembly efficiency of the outer spherical LED display cabinet. Simultaneously, by sharing the bracket structure, the types and number of parts are reduced, making the overall structure more compact and lightweight, improving the assembly efficiency of the outer spherical display cabinet frame and overall heat dissipation performance.

[0116] Optionally, the first base is a first flat plate, and the second connecting structure is a second flat plate, with the first and second flat plates forming an angle. The surface of the first flat plate facing the second base forms a fourth mounting surface, and the second base and the side of the second flat plate away from the first flat plate are welded or riveted together. This angle design between the first and second flat plates allows the fourth mounting surface to face the second base, facilitating the installation and fixation of the power module. Simultaneously, this angle effectively utilizes the three-dimensional space within the outer spherical display cabinet frame, avoiding the spatial limitations imposed by a planar layout. Furthermore, welding or riveting the side of the second base and the second flat plate away from the first flat plate not only ensures the overall robustness of the support structure but also reduces production costs and improves manufacturing efficiency by decreasing the number of independent structural components.

[0117] In this embodiment, the second base body and the second flat plate body are welded to the side away from the first flat plate body. This arrangement optimizes the wiring path between the power module and the HUB board, reducing wiring length and improving the reliability and stability of signal transmission. Simultaneously, the angled design between the first and second flat plates promotes airflow, facilitating heat dissipation for both the power module and the HUB board, further ensuring the long-term stable operation of the outer spherical LED display cabinet.

[0118] In this embodiment, the second base is a third flat plate, and the third flat plate forms a fifth mounting surface opposite to the first base. The third flat plate and the second flat plate are set at an angle; the side of the second flat plate connects to the center of the third flat plate facing the first base. This specific angle between the third and second flat plates not only saves internal space within the cabinet but also improves the overall stability of the support structure, ensuring that the fifth mounting surface can effectively support the HUB board. Simultaneously, the connection between the side of the second flat plate and the center of the third flat plate facing the first base achieves an optimal distance between the power module and the HUB board, reducing signal transmission loss and ensuring high-quality signal transmission. This connection method also helps to create a good airflow path, enhancing heat dissipation and ensuring the normal operating temperature of the electronic components inside the outer spherical LED display cabinet frame, thus extending the lifespan of the outer spherical LED display cabinet.

[0119] Optionally, at least one of the first, second, and third flat plates has a weight-reducing hole; and / or, at least one of the first, second, and third flat plates has a ventilation hole; and / or, at least one of the first, second, and third flat plates is made of carbon steel plate with a thickness greater than or equal to 1.0 mm and less than or equal to 2.0 mm. In this way, the weight-reducing hole can lower the self-weight of the support structure, reduce the additional burden on the outer spherical display cabinet frame, and improve the portability and ease of operation during installation. The ventilation hole enhances air convection inside the outer spherical display cabinet frame, effectively improving the heat dissipation efficiency of the power module and HUB board, ensuring the stability of electronic components under high-load operating conditions and extending their service life. At the same time, using a carbon steel plate of appropriate thickness as the plate material ensures that the structural components have sufficient strength and rigidity, maintaining good load-bearing capacity and structural stability while reducing weight, avoiding structural deformation due to excessively thin material or increased weight due to excessively thick material.

[0120] In this embodiment, the first, second, and third flat plates all have weight-reducing holes. All three plates are made of carbon steel and are 1.5 mm thick. This design achieves multiple objectives: reducing the overall weight of the support structure, enhancing internal airflow, and improving structural strength and stability.

[0121] Optionally, a mounting post is provided on the fifth mounting surface. The mounting post has an internally threaded hole to connect the HUB board and the second base by passing a first fastener through the HUB board and the internally threaded hole. There may be one mounting post; or multiple mounting posts, spaced apart along the length and / or width of the fifth mounting surface. This way, by providing mounting posts on the fifth mounting surface and designing internally threaded holes within them, a secure connection between the HUB board and the second base is achieved through the first fastener. Furthermore, a single mounting post is suitable for fixing small or medium-sized HUB boards; multiple mounting posts, spaced apart along the length and / or width of the fifth mounting surface, allow for flexible adjustment based on the size and weight of the HUB board, making it suitable for fixing HUB boards of various sizes and enhancing the versatility and adaptability of the support structure.

[0122] Multiple mounting posts are spaced apart along the length and width of the fifth mounting surface. This design, with its internal threaded holes, allows the HUB board to be tightly connected to the support structure using bolts or other primary fasteners. This avoids displacement and poor contact issues that can occur with traditional adhesive or snap-fit ​​methods, ensuring the stability of the HUB board and the continuity of signal transmission. Simultaneously, the distribution of these multiple mounting posts also distributes the pressure exerted by the HUB board on the support structure, further improving the stability of the connection and the load-bearing capacity of the structure.

[0123] Optionally, the fourth mounting surface has a first mounting hole to connect the power module and the first base by passing a second fastener through the power module and the first mounting hole; wherein, there is one first mounting hole; or, there are multiple first mounting holes, which are spaced apart along the length and / or width direction of the fourth mounting surface; or, there are multiple sets of first mounting holes, which are spaced apart along the length direction of the fourth mounting surface, and each set of first mounting holes includes multiple sub-mounting holes spaced apart along the width direction of the fourth mounting surface. In this way, by providing a first mounting hole on the fourth mounting surface, a secure connection between the power module and the first base is achieved by passing the second fastener through the power module and the first mounting hole. At the same time, a single first mounting hole, multiple spaced first mounting holes, or multiple sets of sub-mounting holes distributed in different directions provide high installation flexibility and structural reliability. Specifically, the single first mounting hole design is suitable for fixing lightweight, small power modules, simplifying the connection process and reducing costs; multiple first mounting holes are spaced apart along the length and / or width of the fourth mounting surface, allowing for flexible adjustment of the fixing position according to the size and weight of the power module, ensuring optimal layout of the power module within the enclosure, while also dispersing the pressure of the power module on the mounting surface and enhancing connection stability; the first mounting holes are arranged in multiple groups, each group containing multiple sub-mounting holes spaced apart along the width direction, further enhancing design flexibility and the reliability of power module fixing, suitable for power modules of different types and sizes, and providing multiple installation options along the length of the fourth mounting surface, facilitating rapid positioning and fixing of the power module.

[0124] In this embodiment, there are two sets of first mounting holes. Each set of first mounting holes includes multiple sub-mounting hole groups spaced apart along the length direction of the fourth mounting surface, with at least two adjacent sub-mounting hole groups having different distances between them. Each sub-mounting hole group includes two sub-mounting holes spaced apart along the width direction of the fourth mounting surface. Thus, by employing multiple sets of sub-mounting hole groups with different spacings, not only is the adaptability of the outer spherical LED display cabinet to power modules of different sizes improved and the installation process simplified, but the installation stability and heat dissipation efficiency of the power module are also enhanced.

[0125] Specifically, the aforementioned arrangement of the two sets of first mounting holes can accommodate power modules of different sizes. By selecting appropriate sub-assembly hole groups, the power modules can be precisely and stably fixed in the optimal position, optimizing the utilization efficiency of space within the enclosure and reducing additional design and manufacturing costs caused by changes in power module size. Simultaneously, the layout of sub-assembly hole groups with varying spacing allows the fixing point positions to be adjusted according to actual installation requirements and the specific specifications of the power modules. This ensures the shortest signal transmission distance between the power modules and other electrical components within the enclosure, reducing signal attenuation, improving signal transmission quality, and enhancing the compactness of the enclosure's internal structure.

[0126] In this embodiment, the dual mounting holes along the width direction, reinforced at multiple points by the second fastener, effectively improve the connection stability between the power module and the first base. Even when the cabinet moves or vibrates, it ensures that the power module will not shift, thus avoiding problems such as poor wiring contact or signal interruption caused by equipment vibration. This design optimizes the wiring layout inside the outer spherical display cabinet frame, reduces the wiring length between the power module and the HUB board, improves signal transmission quality, and helps enhance the overall performance of the outer spherical LED display cabinet.

[0127] The second connecting structure has a second mounting hole for connecting the outer spherical display cabinet frame and the second connecting structure by passing a third fastener through the second mounting hole. The second mounting hole can be a single hole or multiple holes spaced apart along the length and / or width of the second connecting structure. This allows for a stable connection between the outer spherical display cabinet frame and the support structure by passing the third fastener through the second mounting hole. When the second mounting hole is a single hole, it is suitable for fixing small or lightweight outer spherical display cabinet frames, simplifying the second connecting structure and reducing material costs and assembly complexity. When there are multiple second mounting holes, they can be flexibly adjusted according to the size and weight of the outer spherical display cabinet frame, achieving a multi-point support fixing method, distributing the pressure of the outer spherical display cabinet frame on the second connecting structure, and improving the stability of the connection and the overall strength of the structure.

[0128] In this embodiment, there are multiple second mounting holes, which are spaced apart along the length of the second connecting structure. This arrangement not only ensures a secure connection between the outer spherical display cabinet frame and the support structure, but also adapts to different outer spherical display cabinet frame layouts, enhancing the design's versatility and adaptability, and reducing the need to redesign the second connecting structure. The spherical LED display device also includes a top outer screen support 110, with the second meridian support structure 14 connected to the top outer screen support 110. The top outer screen support 110 is connected to a portion of the multiple outer spherical LED display cabinets 21. The spherical LED display device also includes an inner spherical top support 120, with the second meridian support structure 14 connected to the inner spherical top support 120. The inner spherical top support 120 is connected to a portion of the multiple inner spherical display cabinet frames 311.

[0129] like Figures 24 to 26As shown, the spherical LED display device also includes a first top outer screen structure 130. The first top outer screen structure 130 includes a first top LED display cabinet 1301. The first top LED display cabinet 1301 includes a first top display cabinet frame 13011 and a first top LED display module 13012 disposed on the first top display cabinet frame 13011. The first top display cabinet frame 13011 is disposed on the top outer screen support 110. The first top LED display module is disposed on the top of the first top display cabinet frame.

[0130] The first top outer screen structure is higher than the outer spherical screen structure 20. The tallest of the outer spherical LED display boxes in the outer spherical screen structure 20 form the second top outer screen structure 201. The second top outer screen structures 201 form a first clearance area. The connecting structure passes through the first clearance area, and the top of the connecting structure is higher than the second top outer screen structure. The first top outer screen structure 130 is set so that, when viewed vertically from a position higher than the spherical LED display device, the part of the first top LED display box 1301 that obscures the second top outer screen structure 201 is transparent. This allows a complete display area to be seen from an aerial view, without the spherical support frame 10 appearing in the center of the display area.

[0131] The tallest of the inner spherical LED display cabinets in the inner spherical screen structure 30 form a first top inner screen structure 301. A second clearance area is formed between the multiple inner spherical display cabinet frames 311 of the first top inner screen structure 301. The spherical LED display device also includes a second top inner screen structure 140, which is disposed within the second clearance area. The inner spherical top support 120 is connected to a portion of the multiple inner spherical display cabinet frames 311, wherein the portion of the inner spherical display cabinet frames 311 are the multiple inner spherical display cabinet frames 311 of the first top inner screen structure.

[0132] The second top inner screen structure 140 includes a second top display cabinet frame 1401 and a second top LED display module disposed on the second top display cabinet frame 1401. Both the second top display cabinet frame 1401 and the second top LED display module are circular structures. The second top display cabinet frame is connected to at least one of the multiple inner spherical display cabinet frames 311 of the first top inner screen structure by bolts and nuts.

[0133] The spherical LED display device also includes a waterproof baffle 150 surrounding the sidewall of the first clearance area. The waterproof baffle 150 is connected to at least one of the multiple outer spherical display cabinet frames of the second top outer screen structure. The top of the waterproof baffle 150 is higher than the highest point of the second top outer screen structure. This prevents moisture from entering the top annular maintenance channel from the first clearance area.

[0134] The top outer screen support 110 includes a first support connected to the spherical support frame 10. The first support includes a base frame and a connecting frame mounted on the base frame, with the first top display cabinet frame mounted on the connecting frame. The spherical LED display device also includes a second support 160 located below the first support, connected to the second meridian support structure 14. The second support is located above the inner spherical top support 120.

[0135] The first top display cabinet frame 13011 includes a heat dissipation cylinder and a baffle plate disposed on the top of the heat dissipation cylinder. A first top LED display module 13012 is disposed on the top of the baffle plate, and multiple first top LED display modules 13012 are arranged in a circle. The heat dissipation cylinder includes a first plate and a second plate. The first plate is a circular plate connected to the baffle plate, and has multiple heat dissipation holes; the multiple heat dissipation holes include multiple first heat dissipation channels disposed on the first plate. The second plate is an annular plate connected to a first support, extending circumferentially around and connected to the first plate; the multiple heat dissipation holes include multiple second heat dissipation channels disposed on the second plate. The second plate is connected to a connecting frame.

[0136] By setting first and second heat dissipation channels on the first and second plates respectively, a heat dissipation path from the inside to the outside is formed. This structural design facilitates the direct conduction of heat from the first top outer screen structure to the heat dissipation cylinder, and then dissipates it into the surrounding environment through the heat dissipation channels, thereby significantly improving heat dissipation efficiency and reducing the risk of heat accumulation. Furthermore, the circular plate on the first plate and the annular plate on the second plate cooperate to form a centrally symmetrical heat dissipation channel. This design optimizes airflow distribution, ensuring that air flows evenly from both sides of the first top outer screen structure through the first and second heat dissipation channels, avoiding problems of excessively strong or weak local airflow, thus improving the uniformity and overall effectiveness of heat dissipation. Setting the first and second heat dissipation channels also helps reduce weight. The baffle can be a transparent structure; since the diameter of the baffle is larger than the diameter of the first clearance area, the baffle will not obstruct the LED light-emitting elements of the second top outer screen structure.

[0137] The spherical LED display device also includes a lightning rod, which extends out of the water baffle after passing through the heat sink and the water baffle. The water baffle has an opening slot for the lightning rod to avoid it. A fixed baffle is installed at the opening slot to seal it, forming a second clearance through-hole for the lightning rod to pass through. A support base is also included, with both the heat sink and the second support mounted on it. Preferably, the lightning rod effectively reduces the risk of lightning strikes to the first top outer screen structure, ensuring its safe operation during thunderstorms. The lightning rod's passage through the heat sink and the water baffle ensures smooth guidance of the lightning current, preventing direct lightning strikes to the first top outer screen structure and protecting electronic equipment and personnel. Preferably, the opening slot on the water baffle is specifically designed to provide space for the lightning rod, while the installation of the fixed baffle blocks the opening of the opening slot, forming a second clearance through hole together with the water baffle. This ensures the normal installation and use of the lightning rod, while not compromising the overall waterproof performance. It prevents rainwater from seeping into the spherical support frame through the lightning rod installation point, thus preventing rainwater from contacting the outer spherical LED display box and / or the inner spherical LED display box and causing damage to them.

[0138] The spherical LED display device also includes a cooling system, which comprises a first air conditioning component mounted on the first meridian support structure 13 and / or the latitude support structure 12. This first air conditioning component effectively dissipates heat generated by the inner spherical screen structure 30 and the outer spherical screen structure 20. The cooling system also includes a second air conditioning component, which outputs cooler air to the viewing surface to ensure viewer comfort. Both the first and second air conditioning components include multiple air conditioners.

[0139] This embodiment sets up an inner spherical screen structure 30 and an outer spherical screen structure 20, so that the display can be viewed both inside and outside the spherical support frame 10. That is, the spherical LED display device in this embodiment is a dual-spherical screen display device.

[0140] "Multiple" means that the quantity is two or more.
