Abstract

The invention provides a bumper based on a lattice unit cell honeycomb structure and an automobile. The bumper based on the lattice unit cell honeycomb structure comprises a front board, the lattice unit cell honeycomb structure and a cross bar. Two end surfaces of the lattice unit cell honeycomb structure are connected with the front board and the cross bar respectively, and comprises at least one honeycomb unit. Each honeycomb unit comprises a honeycomb substructure and two layers of connection boards, and the honeycomb substructure is arranged between the two layers of connection boards. The honeycomb substructure is arranged between the adjacent honeycomb units, and comprises at least two tabulate battens; at least one pair of round tubes is arranged on the battens, the central axes of the round tubes are located on the planes of the battens, and two ends of the round tubes are located at two ends of the battens in the width direction respectively. The battens are clamped with each other to form honeycomb pores. The energy absorption capability of the bumper based on the lattice unit cell honeycomb structure can be improved, so that the safety of the automobile and passengers in the automobile can be guaranteed.

Description

technical field

[0001] The invention relates to the technical field of materials, in particular to an automobile bumper and an automobile based on a lattice unit cell honeycomb structure. Background technique

[0002] With the development of automobile technology, the requirements for anti-collision and energy absorption of automobiles during collisions are getting higher and higher. In order to absorb the energy of the collision during a car collision, a car bumper will be provided on the car.

[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 metal bar; the hollow circular tube buffer structure generally has many It consists of two aluminum tubes side by side.

[0004] However, the metal circular tubes on the bumper of the prior art are simply arranged in parallel, so that the energy abso...
