Detailed Description

Further description is provided below with reference to the accompanying drawings.

Fig. 1 shows: a directly-driven front-rear separated sunshade curtain comprises a front curtain structure and a rear curtain structure, and is applied to a skylight frame consisting of two side frames 1 and front and rear frames 2 and 3.

The front curtain structure and the rear curtain structure comprise a curtain cloth roll 4, a scroll 5, a curtain cloth 6, a rope wheel 7, an unreeling motor 8, an unreeling rope 9, a wire arranging wheel 10, an unreeling reversing pulley 11, an unreeling scroll 12, an unreeling spring 13, an unreeling guide pulley 14 and a curtain cloth 15. In this embodiment, taking the previous curtain structure as an example, the curtain fabric roll 4 is supported between the two side frames 1 through the rotatable unwinding curtain fabric 15 of the winding shaft 5, two ends of the winding shaft 5 are connected with the rope wheels 7 in a penetrating manner, and any end of the winding shaft is driven by the unwinding motor 8, the rope wheels 7 wind the unwinding ropes 9, the unwinding ropes 9 wind the unwinding reversing pulleys 11 in the middle part of the side frames through the winding wheels 10 on the side frames 1, the unwinding ropes 9 wind the unwinding guiding pulleys 14 at the end parts of the unwinding shafts 12 after passing through the unwinding reversing pulleys 11, and are connected to the outer ends of the unwinding springs 13 in the unwinding shafts 12, and the inner ends of the unwinding springs 13 are fixedly connected with the unwinding shafts 12.
