Other AbstractThe invention relates to a foldable structure, in particular to a space unfolding structure which can be unfolded without needing a driving device. The space unfolding structure comprises a cylinder, a heater, memory alloys and films. The heater is installed in the cylinder, a plurality of memory alloys are evenly distributed on the periphery of the cylinder in the circumferential direction, one end of every memory alloy penetrates through the cylinder and is connected with the heater, the other end of every memory alloy is a free end, the memory alloys are sleeved with the films in a stacked mode through the free ends of the memory alloys, the films are in sealed connection with the cylinder, the free ends of the memory alloys sleeved with the films are sequentially bent in the clockwise direction and coiled around the cylindrical surface of the cylinder, and an inflation nozzle capable of inflating the cylinder is installed on the cylinder. The space unfolding structure does not need to be driven by a motor, is simple in structure and easy to install and does not occupy too much space, and reliability of the space unfolding structure is greatly improved.
