Claim:
A foldable frame structure, comprising: a limit portion which is a bottom pad that can be placed at a plane; a canopy portion, connected with the limit portion; and a frame body, which is positioned inside the canopy portion for lifting the canopy portion from the limit portion; the frame body is made of an elastic material and comprises a plurality of 8-shaped structures, wherein each 8-shaped structure has one first overlapping end, two cambered areas located at the opposite sides of the first overlapping end, and two contacting ends; in which the two contacting ends contact and press against the limit portion respectively so as to make the first overlapping end a substantial apogee and distant from the limit portion with a height; wherein, each cambered area of the 8-shaped structure is connected with another neighboring cambered area of another 8-shaped structure by a second overlapping end; the plurality of first overlapping ends of the 8-shaped structures are aligned along an extended direction; in addition, by making the 8-shaped structures come into close contact with one another successively and making the cambered areas come into close contact with one another successively, the frame can be collapsed for storage; wherein the frame body contains an odd number of 8-shaped structures that are ranked along the extended direction; in addition, the odd number of 8-shaped structures are formed by only one elastic material in an integrated manner.
