The invention discloses an automobile bumper based on a three-dimensional lattice material. The automobile bumper comprises a cross bar and an anti-collision bracket, an elastic buffer block is arranged between the cross bar and the anti-collision bracket, and the automobile bumper is characterized in that the elastic buffer block comprises the three-dimensional lattice material filled between thecross bar and the anti-collision bracket; the three-dimensional lattice material comprises a plurality of cell body units which are arranged in a spatial extending mode in the transverse direction and the longitudinal direction, each cell body unit comprises two sets of node units which are parallel to each other and arranged oppositely and at least two first wire rods connected between the two sets of node units, and each node unit is composed of four quadrangular nodes; and in any cell body unit, the first wire is wound between the two groups of node units to form the nodes, and two ends ofthe first wire are respectively connected to one node on the two groups of node units. The automobile bumper has the advantages of being good in energy absorption effect, capable of effectively guaranteeing safety of automobiles, drivers and passengers and the like.
Description
technical field [0001] The invention relates to the technical field of new material application, in particular to an automobile bumper based on a three-dimensional lattice material. Background technique [0002] With the development of society and the advancement of science and technology, cars are becoming more and more popular among people. The popularization of cars has brought great convenience to people's lives, but it has also brought safety problems. In order to improve the safety of cars, developers have added many protective devices to cars, and car bumpers are one of them. The bumper is a device located at the front of the car body. When a collision occurs, it can absorb and slow down the external impact and protect the car body. [0003] In the prior art, the bumper of an automobile is mainly composed of a metal beam, a metal bar and a hollow circular tube buffer structure, and the hollow circular tube buffer structure is arranged between the metal beam and the m...
