The invention discloses a self-locking type energy absorption structure which comprises a self-locking type multi-cell energy absorption structure formed by a plurality of self-locking type unit cell energy absorption structures in an array mode, each self-locking type unit cell energy absorption structure comprises at least three bending units, each bending unit comprises a connecting section and locking sections arranged on the two sides of the connecting section in a rotational symmetry mode, each locking section comprises at least three bending plates, and the bending plates are arranged on the connecting sections. The bending angles between the bending plates are the same, a hollow cell is formed, and the bending units are evenly nested in the same hollow cell according to angle distribution to form the self-locking type unit cell energy absorption structure. According to the self-locking type unit-cell energy absorption structure, arrays are continuously nested to form a multi-cell energy absorption structure, self-locking is achieved between the adjacent bending units through deformation coupling and mutual friction, the energy absorption characteristic of the multi-cell structure can be kept while structural locking is achieved, the whole energy absorption structure is simple, the manufacturing process is simple, the manufacturing cost is low, and engineering application is easy to achieve.

    本发明公开了一种自锁型吸能结构,包括多个自锁型单胞吸能结构阵列形成的自锁型多胞吸能结构,自锁型单胞吸能结构包括至少三个折弯单元,折弯单元包括连接段和设在连接段两侧旋转对称的锁定段,锁定段包括至少三个折弯板,折弯板之间折弯角度相同且形成一个空胞,折弯单元之间通过在同一空胞内按角度分布均匀嵌套形成自锁型单胞吸能结构,本发明通过将多个折弯单元通过嵌套的方式组成自锁型单胞吸能结构,自锁型单胞吸能结构通过不断嵌套阵列组成多胞吸能结构,相邻折弯单元之间通过变形耦合和互相摩擦实现自锁,结构锁定的同时能够保持多胞结构的吸能特性,整个吸能结构结构简单,制作工艺简单、制备成本低,易实现工程化应用。
