The invention belongs to the technical field of automobile parts, and particularly relates to a multi-stage buffer light-weight bumper. A buffer layer, a first buffer support and a first buffer blockform a first-layer grid structure; a second buffer support, a second buffer block and a third buffer support form a second-layer grid structure; an existing integrated metal structure is replaced withthe grid structure design of the double-layer buffer support, and the overall weight of the bumper is greatly reduced through the grid structure; and meanwhile, the grid structure is beneficial to direction dispersion of impact force, so that the safety is guaranteed.

    本发明属于汽车零部件技术领域,具体涉及一种多级缓冲轻量化保险杠;缓冲层、第一缓冲支架、第一缓冲块形成了第一层网格结构,第二缓冲支架、第二缓冲块、第三缓冲支架形成了第二层网格结构,利用双层缓冲支架的网格结构设计取代了现有的一体化金属结构,网格化结构大量减少了保险杠整体重量,实现了轻量化,同时网格化结构有利于冲击力的方向分散,保障了安全性。
