The invention relates to a single-degree-of-freedom paraboloid type foldable and unfoldable array, which is designed on the basis of a rigid thick plate paper-cut theory. The array comprises a rigid thick plate and a spring driving hinge; the rigid thick plate is provided with a special molded surface, and the spring driving hinge is arranged at the crease of a basic folding and unfolding unit; the surface appearance and the side face of the rigid thick plate are treated in a material adding and cutting mode so as to meet the self-locking and profile requirements. According to the single-degree-of-freedom paraboloid type foldable and unfoldable array, the array is driven to be freely folded and unfolded by means of the elastic force of the spring, is folded into a small size in a non-working state and is unfolded to a preset working position in a working state, and the single-degree-of-freedom paraboloid type foldable and unfoldable array has the advantages of single degree of freedom,stable structure, large
