The invention provides a multi-spiral rigid foldable tubular structure which comprises a plurality of truncated cone units which are connected in the axial direction, and the lengths of adjacent side edges of the truncated cone units in the axial direction are unequal, so that the tubular structure formed by connecting the truncated cone units in the axial direction is spiral. The truncated cone units are provided with adjacent side edges with the same length in the circumferential direction so that the tubular structures of the truncated cone units can be folded in the circumferential direction. The head end of the tubular structure can be closed according to needs, the foldable characteristic of the tubular structure is not affected, the tubular structure can be connected through the side edges in the circumferential direction, the foldable tubular structure with the multiple channels is formed, the foldable tubular structure can be applied to the fields of aerospace, robots, building structures and the like, and the problem that in the foldable tubular structure with the bent axis, the foldable tubular structure cannot be folded easily is solved. The problems that the bent section folding tubular structure is complex in shape and limited in application field exist.

    本发明提供一种多重螺旋形刚性可折叠管状结构,包括若干个沿轴向相连接的截锥体单元,截锥体单元在轴向上的邻侧棱边长度不等,以使轴向上若干个截锥体单元连接形成的管状结构呈螺旋形,截锥体单元在周向上具有长度相等的邻侧棱边,以使截锥体单元的管状结构在周向上具备可折叠性。本发明通过使管状结构的头端可根据需要封闭且不影响其可折叠的特性,且管状结构可在周向上通过侧边相连接,形成具有多个通道的可折叠管状结构,可以应用于航空航天、机器人、建筑结构等领域,以解决在弯曲轴线的折叠管状结构中,存在弯曲段折叠管状结构形状复杂可应用领域有限的问题。
