Annular rigid origami unit lattice structure

The invention relates to an annular rigid origami unit lattice structure which comprises a plurality of annular rigid origami units. The annular rigid paper folding unit comprises an upper polygonal annular plate, a lower polygonal annular plate and a plurality of rigid paper folding plates, the inner layer and the outer layer of the upper polygonal annular plate (N side lengths) are connected with the inner layer and the outer layer of the lower polygonal annular plate (N side lengths) through the N rigid paper folding plates respectively, and the upper edges and the lower edges of the rigid paper folding plates are connected with the upper polygonal annular edges and the lower polygonal annular edges respectively. Compared with an existing light space lattice structure, the structure has the advantages of multiple deformation modes, adjustable rigidity and stable bearing capacity. The annular rigid origami unit lattice structure is applied to buffering, vibration isolation, impact resistance and energy abso
