The invention provides an anti-collision structure of a spacecraft and the spacecraft, relates to the technical field of spaceflight, and solves the technical problem that the spacecraft is difficult to effectively cope with collision. The anti-collision structure comprises a beam piece and a metamaterial structure, the whole beam piece is in an arc shape and is provided with a convex side and a concave side, and the metamaterial structure is connected to the concave side of the beam piece; the metamaterial structure comprises a plurality of first wall plates parallel to a first direction and a plurality of second wall plates parallel to a second direction, and the plurality of first wall plates and the plurality of second wall plates are mutually crossed to form a plurality of first cell element structures arranged in an array; wherein the first direction is perpendicular to the second direction, and the first wall plate and the second wall plate intersect to form a plurality of intersecting wall sections arranged in an array mode; the first cell structure is a square cylindrical structure; the metamaterial structure further comprises a plurality of second cell element structures, and the central axes of the second cell element structures coincide with the central axis of the intersecting wall section. According to the anti-collision structure, on the basis that the rigidity is ensured, energy absorption is improved, and collision can be effectively coped with.

    本发明提供了一种航天器的防撞结构、航天器,涉及航天技术领域,解决了航天器难以有效应对撞击的技术问题。该防撞结构包括梁件和超材料结构,梁件的整体呈弧状且具有凸侧和凹侧,超材料结构连接在梁件的凹侧;超材料结构包括多个平行于第一方向的第一壁板和多个平行于第二方向的第二壁板,多个第一壁板和多个第二壁板相互交叉形成阵列排布的多个第一胞元结构;其中,第一方向垂直于第二方向,第一壁板和第二壁板相交形成多个阵列排布的相交壁段;第一胞元结构为方形的筒状结构;超材料结构还包括多个第二胞元结构,第二胞元结构的中心轴线与相交壁段的中心轴线重合。该防撞结构在确保刚度的基础上,提高能量吸收,能够有效应对撞击。
