For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0026] Please refer to Figures 1 - 4 , this embodiment provides a retractable roof system, including a domed roof 100 and a retractable roof 200. The center of the domed roof 100 has a circular opening 101. The retractable roof 200 is arranged on the domed roof 100 and consists of several petal-shaped roof sheets 210. The roof sheets 210 can move along the radial direction of the domed roof 100 to switch between an open state and a closed state. In the open state, the circular opening 101 is completely exposed; in the closed state, the retractable roof 200 completely covers the circular opening 101 to form a closed dome structure.

[0027] The retractable roof system provided by the present utility model enables the venue to realize the mutual conversion between indoor and outdoor spaces by driving the roof sheets 210 to move along the radial direction of the domed roof 100 to switch between the open state and the closed state, thereby making full use of natural conditions. It has the advantages of novel opening and closing method, reasonable structural force, convenient drive control, etc., enriches the structural form of the retractable roof 200, and has good application prospects.

[0028] Preferably, a plurality of tracks are distributed circumferentially on the domed roof 100. The tracks extend along the radial direction of the domed roof 100 and correspond to the roof sheets 210 one by one. A moving mechanism 300 is respectively arranged below each roof sheet 210. The moving mechanism 300 is used to drive the roof sheet 210 to move along the corresponding track. In this embodiment, there are 12 roof sheets 210, 12 tracks, and 12 tracks are correspondingly arranged below the 12 roof sheets 210. Of course, the present utility model does not limit the number of roof sheets 210. Preferably, the number of roof sheets 210 is an integer multiple of 3, so as to be divisible by 360°.

[0029] Furthermore, a plurality of tooth grooves are arranged axially on the track. The moving mechanism 300 includes a traveling gear and a driving unit. The traveling gear is rotatably installed below the roof sheet 210, and the traveling gear meshes with the tooth grooves. The driving unit is connected to the traveling gear and is used to drive the traveling gear to move along the track. Driving the traveling gear to move along the track by means of meshing transmission, and then driving the roof sheet 210 to move along the track, has stable transmission, high reliability and transmission efficiency, which is a better choice. Of course, in addition to meshing transmission, other well-known moving methods in the art, such as the cooperation of a slide rail and a slider, can also be used, and the present utility model will not elaborate.

[0030] It should be noted that the track is not a straight line, but a circular arc extending along the radial direction of the domed roof 100. Therefore, the movement trajectory of the roof sheet 210 should also be an arc line. And, the movement of all the roof sheets 210 should be synchronous to enable the retractable roof system to switch between the open state and the closed state.

[0031] As a preferred example in this embodiment, in the open state, the roof sheet 210 moves integrally above the domed roof 100. That is to say, the roof sheet 210 can move integrally along the radial direction of the domed roof 100. In the open state, the roof sheet 210 moves radially outward along the domed roof 100 to above the domed roof 100 so that the circular opening 101 is completely exposed; in the closed state, the roof sheet 210 moves radially inward along the domed roof 100 to completely cover the circular opening 101 to form a closed dome structure.

[0032] As a preferred example in this embodiment, as Figures 3 - 4 shown, the roof sheet 210 is divided into a moving part 211 and a rotating part 212 along the radial direction of the domed roof 100. The rotating part 212 is closer to the center of the domed roof 100 than the moving part 211, and the rotating part 212 can rotate upward / downward relative to the moving part 211. That is to say, when the opening and closing roof system needs to switch to the open state, the moving part 211 and the rotating part 212 move integrally radially outward along the domed roof 100. At the same time, the rotating part 212 can also rotate upward / downward relative to the moving part 211. In this embodiment, when the moving part 211 moves in place, the rotating part 212 is exactly perpendicular downward along the circumference of the circular opening 101.

[0033] The difference between the above two preferred examples is that in the previous preferred example, the roof sheet 210 moves integrally, so the size of the domed roof 100 needs to be made larger to accommodate the entire opening and closing roof 200, while in the latter preferred example, the roof sheet 210 is divided into a moving part 211 and a rotating part 212, and the rotating part 212 can be perpendicular downward along the circumference of the circular opening 101, so the size of the domed roof 100 can be made relatively smaller. Therefore, the above two structural forms can be selected according to actual needs, and the present invention does not limit this.

[0034] Furthermore, an electric push rod is provided on the moving part 211, and the telescopic end of the electric push rod is connected to the rotating part 212. The electric push rod is used to drive the rotating part 212 to rotate relative to the moving part 211. In the closed state, the rotating part 212 folds downward from the circular opening 101. The electric push rod can drive the rotating part 212 to rotate relative to the moving part 211 through telescoping. For example, when the opening and closing roof system needs to switch from the open state to the closed state, the electric push rod extends to drive the rotating part 212 to rotate upward relative to the moving part 211. When the opening and closing roof system needs to switch from the closed state to the open state, the electric push rod retracts to drive the rotating part 212 to rotate downward relative to the moving part 211. Of course, in addition to using the electric push rod to drive the rotating part 212 to rotate, other drive mechanisms well-known to those skilled in the art can also be used, and the present invention does not limit this.

[0035] Preferably, the rotating part 212 is a membrane structure, such as an ETFE membrane structure, and the present utility model does not limit this.

[0036] Preferably, the moving part 211 includes a framework and a roof panel, and the roof panel is fixed on the framework. In this embodiment, the framework is, for example, a metal framework, such as an aluminum alloy framework, and the roof panel is, for example, an aluminum magnesium manganese plate, and the present utility model does not limit this.

[0037] In summary, the embodiment of the present utility model provides an opening and closing roof system. By driving the roof sheet 210 to move radially along the domed roof 100 to switch between the open state and the closed state, the indoor and outdoor spaces of the venue can be mutually converted, thereby making full use of natural conditions. It has the advantages of novel opening and closing method, reasonable structural stress, convenient drive control, etc., enriches the structural form of the opening and closing roof 200, and has good application prospects.

[0038] In addition, it should also be recognized that although the present utility model has been disclosed above with preferred embodiments, the above embodiments are not intended to limit the present utility model. For any person skilled in the art, without departing from the scope of the technical solution of the present utility model, many possible changes and modifications can be made to the technical solution of the present utility model by using the technical content disclosed above, or it can be modified into an equivalent embodiment with equivalent changes. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model without departing from the content of the technical solution of the present utility model still belong to the scope of protection of the technical solution of the present utility model.
