The utility model discloses a theory of operation is:

the driving device can act on the curtain bottom sheet 6 to drive the curtain bottom sheet to slide along the guide rail 1. The curtain piece structure formed by hinging the upper sunshade piece 4 and the lower sunshade piece 5 is similar to an organ shape, and the sliding of the curtain bottom piece 6 drives the curtain bottom piece to extend, shade or contract and fold. Meanwhile, the tails of the upper sunshade pieces 4 and the lower sunshade pieces 5 of the adjacent group are meshed and driven through the transmission gear 3, so that the whole sunshade is in linkage relation, and as long as the curtain bottom piece 6 is driven to slide, the rotation amplitudes of all the upper sunshade pieces 4 and the lower sunshade pieces 5 are corresponding, and the problem that the local upper sunshade pieces 4 or the local lower sunshade pieces 5 are different in extension or contraction amplitude can not occur.

Meanwhile, the shading parts 7 of the upper shading sheet 4 and the lower shading sheet 5 on the front side edges are matched with the light-transmitting gap 8, and when the upper shading sheet 4 and the lower shading sheet 5 are completely extended and shaded, the shading parts 7 are covered on the light-transmitting gap 8 for complete shading. When the upper sunshade plate 4 and the lower sunshade plate 5 slightly contract, fold and swing, the shading part 7 can swing and open, so that light rays and fresh air can realize semi-transparent ventilation through the light-transmitting gap 8.

It should be noted that the gear ratio of the transmission gear 3 between the upper sunshade 4 and the lower sunshade 5 of adjacent groups is not necessarily one to one. If the height of the upper sunshade plate 4 is equal to the height of the lower sunshade plate 5, the upper sunshade plate 4 and the lower sunshade plate 5 form an isosceles triangle structure, the rotation directions of the upper sunshade plate 4 and the lower sunshade plate 5 are opposite, the amplitudes of the upper sunshade plate and the lower sunshade plate are equal, and the transmission ratio of one to one is also adopted in the connection transmission parts of adjacent groups. However, if the height of the upper sunshade 4 is not equal to the height of the lower sunshade 5, the triangular structure formed by the upper sunshade and the lower sunshade is not a simple isosceles triangle, the rotation amplitudes of the upper sunshade 4 and the lower sunshade 5 are not equal, and the connection transmission parts of adjacent groups can also adopt corresponding transmission ratios to realize special linkage effect.

If half-open ventilation and light transmission of the upper sunshade plate 4 and the lower sunshade plate 5 are needed, the curtain bottom plate 6 can be controlled to slide for a short stroke, the upper sunshade plate 4 and the lower sunshade plate 5 are driven to be folded in a small range, and therefore half-ventilation and light transmission are achieved.

However, the solution of this embodiment will result in the bottom panel 6 being at a certain height from the bottom in the half-open air-permeable and light-permeable state, and the partial space is in the full-open state. The height stroke is about 10% -30% of the whole sunshade stroke, and is determined by the half-open amplitude.
