[0046] Reference Figure 1-Figure 3 A spherical cap display screen provided in an embodiment of the present application includes a spherical cap body, a display screen (not shown in the figure) disposed on the spherical cap body, and a control system (not shown in the figure) located in the spherical cap body. The spherical cap body includes a spherical cap bracket 10 and a spherical cap box 20 disposed on the spherical cap bracket 10. The spherical cap bracket 10 includes a plurality of sub-brackets 14 enclosed and spliced, and each sub-bracket 14 is spliced ​​from the inside to the outside by a first structure frame 11, a second structure frame 12, and a third structure frame 13; and the spherical cap box 20 includes a plurality of first boxes 21, a plurality of second boxes 22, and a plurality of third boxes 23. The plurality of first boxes 21 enclose a first curved surface 30 located in the inner circle, the plurality of second boxes 22 enclose a second curved surface 40 located in the middle circle, and the plurality of third boxes 23 enclose a third curved surface 50 located in the outer circle. The second curved surface 40 is disposed outside the first curved surface 30, and the third curved surface 50 is disposed outside the second curved surface 40.

[0047] In the embodiment of the present application, the spherical cap bracket 10 is modularized and formed by enclosing and splicing a plurality of sub-brackets 14, and each sub-bracket 14 is formed by splicing three structural frames. At the same time, the spherical cap box 20 is also formed by splicing a plurality of modular first boxes 21, second boxes 22 and third boxes 23. The spherical cap bracket 10 and the spherical cap box 20 are then assembled to form a spherical cap main body. This splicing assembly structure is simple, low-cost, easy to install, and greatly improves efficiency.

[0048] Reference Figure 4 , Figure 5 In the embodiment of the present application, the first structural frame 11 includes a plurality of first arc blocks 111 which are concentrically arranged from the inside to the outside and spaced apart, and first side plates 112 which are respectively connected to both ends of the plurality of first arc blocks 111. When the first structural frame 11 is assembled, it is located at the center of the spherical cap. Therefore, after the plurality of first arc blocks 111 and the first side plates 112 are assembled, the shape is closer to a fan shape. On the two first side plates 112, upright first support plates 113 are respectively provided.

[0049] Reference Figures 7 to 10 , the second structural frame 12 and the third structural frame 13 are closer to the outside of the spherical cap when assembled with the first structural frame 11, so the appearance of the second structural frame 12 and the third structural frame 13 is closer to the fan ring. Specifically, the second structural frame 12 includes a plurality of second arc blocks 121 that are concentrically and spaced from the inside to the outside, and second side plates 122 that are respectively connected to the two ends of the plurality of second arc blocks 121, and upright second support plates 123 are respectively provided on the two second side plates 122; the third structural frame 13 includes a plurality of third arc blocks 131 that are concentrically and spaced from the inside to the outside, and third side plates 132 that are respectively connected to the two ends of the plurality of third arc blocks 131, and upright third support plates 133 are respectively provided on the two third side plates 132.

[0050] When the first structural frame 11, the second structural frame 12 and the third structural frame 13 are spliced ​​to form a sub-bracket 14, they can be spliced ​​sequentially from the inside to the outside, or from the outside to the inside. When the first structural frame 11 is spliced ​​with the second structural frame 12, the first arc block 111 on the outer layer of the first structural frame 11 is fixedly connected with the second arc block 121 on the inner layer of the second structural frame 12, and when spliced ​​with the third structural frame 13, the second arc block 121 on the outer layer of the second structural frame 12 is fixedly connected with the third arc block 131 on the inner layer of the third structural frame 13. When fixedly connected, two adjacent arc blocks are locked and fixed by fasteners such as screws, so that the assembly of a sub-bracket 14 is completed.

[0051] In this embodiment, there are eight sub-brackets 14. Of course, there may be six or ten sub-brackets 14. Eight sub-brackets 14 are enclosed and spliced ​​to form a spherical crown bracket 10. The fixed connection between two adjacent sub-brackets 14 is achieved by fixing the adjacent first side plates 112 to the first side plates 112, the second side plates 122 to the second side plates 122, and the third side plates 132 to the third side plates 132.

[0052] Reference Figure 1 and Fig.11 The ball crown bracket 10 also includes a support frame 15, which includes a plurality of cross bars 151, a plurality of longitudinal bars 152, and a vertical bar 153 arranged at the intersection of the cross bars 151 and the longitudinal bars 152. Specifically, there are five cross bars 151 and five longitudinal bars 152. The two cross bars 151 located on the outside are shorter than the three cross bars 151 in the middle, and the two longitudinal bars 152 located on the outside are shorter than the three longitudinal bars 152 in the middle. The cross bars 151 and the longitudinal bars 152 are arranged crosswise to form a mounting plane, and the vertical bar 153 is arranged at the intersection of the cross bars 151 and the longitudinal bars 152. After the ball crown bracket 10 is assembled, its interior is concave, which is not convenient for its installation and fixing. A support frame 15 is arranged inside the ball crown bracket 10 to facilitate the installation of the ball crown bracket 10. The fixing of the ball crown bracket 10 and the support frame 15 is achieved by the vertical bar 153. During assembly, the plurality of vertical rods 153 are fixedly connected to the upright first support plates 113 , the second support plates 123 and the third support plates 133 on the spherical crown bracket 10 .

[0053] Further, refer to Figure 4 and Fig.12 In this embodiment, there are six first boxes 21, twelve second boxes 22, and twelve third boxes 23.

[0054] Reference Fig.13 , Fig.14 The cross section of the first box body 21 is roughly fan-shaped, including a plurality of evenly arranged first warp plates 211 and a plurality of first weft plates 212 for fixing the plurality of first warp plates 211. The space formed by the plurality of first warp plates 211 and the plurality of first weft plates 212 can be used to place the power supply in the control system, the display module of the display screen, etc. When two adjacent first boxes 21 are enclosed and connected, the two adjacent first warp plates 211 are fixedly connected by fasteners such as screws. In this way, in this embodiment, the six first boxes 21 enclose to form a first curved surface 30 located in the inner circle.

[0055] Reference Figures 15 to 18, the second box 22 and the third box 23 are spliced ​​on the outside of the first box 21, so the cross-sections of the second box 22 and the third box 23 are fan-shaped. The second box 22 includes a plurality of uniformly arranged second warp plates 221 and a plurality of second weft plates 222 for fixing the plurality of second warp plates 221. Similarly, when two adjacent second boxes 22 are connected, the two adjacent second warp plates 221 are fixed by screws. In this embodiment, there are twelve second boxes 22, and the twelve second boxes 22 enclose a second curved surface 40 located in the middle circle. The third box 23 includes a plurality of uniformly arranged third warp plates 231 and a plurality of third weft plates 232 for fixing the plurality of third warp plates 231. Similarly, when two adjacent third boxes 23 are connected, the two adjacent third warp plates 231 are also fixed by screws. In this embodiment, there are twelve third boxes 23, and the twelve third boxes 23 enclose a third curved surface 50 located in the outer circle. When the first curved surface 30 is spliced ​​with the second curved surface 40, the first box body 21 and the second box body 22 are fixedly connected by the adjacent first weft plate 212 and the second weft plate 222. When the second curved surface 40 and the third curved surface 50 are spliced ​​with the adjacent second box body 22 and the third box body 23 are fixedly connected by the adjacent second weft plate 222 and the third weft plate 232.

[0056] In this embodiment, since there are six first boxes 21, and twelve second boxes 22 and third boxes 23, two second boxes 22 and two third boxes 23 can be installed on the outside of one first box 21, that is, the two first warp plates 211 on the outside of one first box 21 are aligned with the two second warp plates 221 on the outside of two second boxes 22, and are also aligned with the two third warp plates 231 on the outside of two third boxes 23. In this way, during assembly, one first box 21 can be assembled with two second boxes 22 and two third boxes 23 first, and then assembled. It is also possible to first splice multiple first boxes 21 and then splice multiple second boxes 22 and multiple third boxes 23.

[0057] After the spherical cap bracket 10 and the spherical cap box 20 are respectively spliced, the two are assembled. Specifically, the first weft plate 212 of the first box 21, the second weft plate 222 of the second box 22, and the third weft plate 232 of the third box 23 are respectively provided with a first connection hole 60, the first arc block 111 of the first structural frame 11, the second arc block 121 of the second structural frame 12, and the third arc block 131 of the third structural frame 13 are respectively provided with a second connection hole 70, and the first connection hole 50 and the second connection hole 60 are locked by fasteners, so that the spherical cap bracket 10 and the spherical cap box 20 are assembled.

[0058] After the main body of the ball crown is installed, the display screen and the control system are installed. Due to the adoption of the above modular structure, the main body of the ball crown is easy to install and disassemble with low cost.

[0059] The above description is only a specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
