Abstract

The invention discloses a reflective surface system which can unfold the space, comprising a foldable ring rod, a foldable rib rod, a connecting joint, a central cylinder, and an air aerated circular ring and a driving rope. The foldable ring rod (1) and the foldable rib rod (3) are respectively connected to the ring rod connecting joint (2) and the rib rod connecting joint (4), forming a ring-rib structure; the ring-rib structure is connected to the central cylinder (7) via a ring rib connecting joint (5) and a rib cylinder connecting joint (6); the air aerated circular ring (8) and the driving rope (9) are provided on the grid skeleton in crossing way to form the reflective surface structure. The air aerated circular ring can be solidified after the molding to enhance the structure precision of the reflective surface; the driving rope can enhance the structure precision of the reflective surface; the metal net or the aluminum plating film structure bound to the driving rope eventually form the expected large foldable reflective surface. The invention is used for forming a large foldable device of the foldable antenna, the reflector or gathers.
