Embodiment Construction

[0017] see figure 1 As shown, the present invention is composed of a bumper beam 1 and a bionic energy-absorbing box 6. The bumper beam 1 is composed of a front arc-shaped panel 2, a rear arc-shaped panel 4 and a cover plate 3. The bionic reinforcing rib 5 is welded, and several bionic reinforcing ribs 5 are distributed on the outline of the bumper beam 1. The existence of the bionic reinforcing rib 5 can ensure a certain rigidity of the bumper beam 1 while improving its bending resistance. Stablize. The crash box 6 is arranged on the rear arc-shaped panel 4 .

[0018] see figure 2 As shown, the bionic energy-absorbing box 6 is composed of a bionic shell 7, a bionic inner tube 8 and a restraint rib 9. The bionic shell 7 is a variable-wall hexagonal tube with the same inner diameter and different wall thickness, and the wall thickness is from top to bottom. Gradually increasing, the bionic shell 7 is composed of a first section shell 71, a second section shell 72, and a thi...

Abstract

The invention discloses a bumper system imitating a bamboo structure. The bumper system is composed of a bumper crossbeam and energy absorption boxes. The bumper crossbeam is composed of a front circular arc face plate, a back circular arc face plate and cover plates. Biomimetic strengthening ribs are welded to the outline of the bumper crossbeam, and the multiple biomimetic strengthening ribs are distributed on the outline of the bumper crossbeam. Each biomimetic energy absorption box is composed of a biomimetic shell, a biomimetic inner tube and constraint rib plates, wherein the biomimetic shell and the biomimetic inner tube are each composed of variable-wall-thickness hexagonal tubes with the same inner diameter and different wall thicknesses, and the wall thicknesses gradually increase from top to bottom; and the six constraint rib plates are distributed uniformly in the circumferential direction and enable the biomimetic shell to be connected with the biomimetic inner tube. The biomimetic strengthening ribs of the bumper crossbeam can strengthen collision properties of vehicles. The energy absorption capacity of the biomimetic energy absorption boxes is increased, and the peak value of collision of the bumper system is reduced while specific energy absorption of the biomimetic energy absorption boxes is improved. Light weight and high efficiency of the bumper system are achieved through the combination of the bumper crossbeam and the biomimetic energy absorption boxes.

Description

technical field [0001] The invention relates to an energy-absorbing structure of a bumper system, in particular to a bionic energy-absorbing structure. Background technique [0002] In the process of road driving in our country, the safety of car collisions has always been a topic of concern, and the lightweight and high energy absorption design of cars has become a hot topic in the automotive field today. Therefore, designing a reasonable energy-absorbing structure at the front and rear of the vehicle is one of the effective measures to reduce injuries to members after a collision. The bumper system is mainly composed of bumper beams, energy-absorbing boxes and mounting brackets. Among them, the crossbeam is a key component of automobile collision safety. Its main function is to evenly transmit the collision energy to the energy-absorbing box, and at the same time prevent excessive intrusion from causing damage to the front parts of the engine, and at the same time cause t...
