The invention discloses an external energy absorption and shock absorption anti-collision structure suitable for a pilotless automobile, which comprises an anti-collision strip, the anti-collision strip is provided with a plurality of groups of basic units forming a pentagonal frame type structure, and the plurality of groups of basic units are spliced and assembled with one another; a frame type structure formed among the multiple sets of anti-collision strips comprises multiple sets of damping grooves. The light-weight materials and the 3D printing technology are adopted, production of the basic unit modules can be completed, the basic combination modules can be freely assembled, an anti-collision structure is achieved, and the production and manufacturing cost and difficulty are reduced; for the collapsing mode of the whole bumper after impact, impact force is transmitted to each unit, and each unit collapses and absorbs energy according to fixed nodes; after different impact forces are applied, the energy absorption points of each unit are collapsed one by one according to the force, unabsorbed energy is transmitted to the next unit, and then the next unit continues to perform the collapsing energy absorption process.
本发明公开了一种适用于无人驾驶汽车的外部吸能减震防撞结构,包括:防撞条,所述防撞条设置有若干组形成五边形框架式结构的基础单元,若干组所述基础单元之间相互拼接组装,若干组所述防撞条之间形成的框架式结构中包括若干组减震槽。本发明采用轻量化材料,3D打印技术,可完成基础单元模块生产,基础组合模块可自由拼装,实现防撞结构,降低了生产制造成本及难度;为撞击后整个保险杠的溃散方式,撞击力传导置每个单元,每单元按固定节点溃散吸能;受到不同的撞击力后,每单元的吸能点会根据力度逐一溃散,并将未吸收的能量传递置下一个单元,然后下一单元继续进行溃散吸能过程。
