[0028] The horizontal rail rod 210 can be installed on the wall or curtain box by means of screws, clips or other connecting structures. The suspension assembly 220 is connected to the top side of the BIPV curtain module 100. The bottom side of the BIPV curtain module 100 hangs down under the action of gravity. Each of the suspension assemblies 220 is arranged along the length direction of the BIPV curtain module 100, so that when each suspension assembly 220 moves along the length direction of the horizontal rail rod 210, it can unfold or retract the BIPV curtain module 100.

[0029] In some embodiments of this utility model, such as Figure 2 , 3 As shown, the suspension assembly 220 includes a hanging ring 221 and a first connecting member 222. The hanging ring 221 is sleeved on the horizontal rail member 210, and the hanging ring 221 and the first connecting member 222 are rotatably connected. The first connecting member 222 is connected to the BIPV curtain module 100. Specifically, the axial direction of the rotation axis of the hanging ring 221 and the first connecting member 222 is vertically downward.

The driving rod 320 passes through the driven component 330. The driven component 330 can be restricted from rotation by the guide structure or the curtain track module 200. So when the driving component 310 drives the driving rod 320 to rotate, the driven component 330 moves along the length direction of the curtain track module 200 to drive the BIPV curtain module 100 to unfold or fold.

[0036] In some embodiments of this utility model, such as Figure 3 As shown, the horizontal rail member 210 is centrally arranged along the length direction, and a strip-shaped through hole 211 is provided on the peripheral wall of the horizontal rail member 210 along the length direction.

[0037] The driven component 330 is partially located inside the horizontal rail 210 and partially extends out of the strip-shaped through hole 211. The portion of the driven component 330 extending out of the strip-shaped through hole 211 is connected to the BIPV curtain module 100. The strip-shaped through hole 211 can restrict the rotation of the driven component 330, and the driven component 330 can move along the length direction of the horizontal rail 210.

[0038] In some embodiments of this utility model, the driven component 330 includes a threaded female 331 and a second connecting member 332. The threaded female 331 is sleeved on the driving rod 320 and engages with the driving rod 320 through a threaded structure.

[0039] A threaded hole is provided in the threaded nut 331, which is sleeved on the drive rod 320. The outer peripheral wall of the threaded nut 331 is provided with a vertically downward rotating shaft. The second connector 332 is rotatably connected to the threaded nut 331 through the rotating shaft. The second connector 332 and the threaded nut 331 rotate relative to each other, making the BIPV curtain module 100 fold or unfold more smoothly.

[0040] In some embodiments of this utility model, along the unfolding direction of the BIPV curtain module 100, the driven component 330 is located at the front end of each suspension component 220. When the driving component 310 is running, it can drive the driven component 330 located at the front end of each suspension component 220 to move, thereby pulling the BIPV curtain module 100 forward or backward, pulling the BIPV curtain module 100 to drive each suspension component 220 forward or to press down each suspension component 220 so that the BIPV curtain module 100 folds.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
