Example Embodiment

[0023] The description will be further elaborated below in conjunction with specific embodiments.

[0024] A kind of highly efficient and stable energy-absorbing automobile collision energy-absorbing box provided by this embodiment, such as figure 1 As shown, it includes a flange 101 , a square thin-walled shell 102 , a lattice structure 103 and a sandwich plate 104 . The flange 101 is arranged on the upper and lower ends of the square thin-walled shell 102, the lattice structure 103 is arranged on the upper and lower ends of the sandwich plate 104, and the lattice structure 103 and the sandwich plate 104 are placed in the square thin-walled shell 102 as a whole .

[0025] Wherein, the square thin-walled shell 102 such as figure 2 As shown, the material is light aluminum alloy, and the wall is provided with triangular defect holes 201 at intervals along the circumferential direction. Since the initial peak force of the square cross-section is small, it can effectively absor...

Abstract

The invention provides an automobile collision energy absorbing box capable of achieving high-efficiency and stable energy absorption. The automobile collision energy absorbing box comprises flanges,a square thin-walled outer shell, lattice structures and a sandwich plate; the flanges are arranged at the upper and lower ends of the square thin-walled outer shell, the lattice structures are arranged on the upper and lower ends of the sandwich plate, and the lattice structures and the sandwich plate are integrally arranged in the square thin-walled outer shell; each lattice structure is formedby distributing aluminum tubes according to the body square diagonal; the sandwich plate comprises two layers of carbon fiber sheets and a honeycomb structure arranged between the two layers of carbonfiber sheets; the honeycomb structure is formed by staggered distribution of regular octagons and regular squares; the lattice structures and the sandwich plate are connected into a whole through spot welding, and the square thin-walled outer shell and the flanges are connected into a whole through spot welding; and the flanges are connected and fixed to a transverse beam and a longitudinal beamof an automobile through bolts. The automobile collision energy absorbing box solves the problems that a traditional energy absorbing box is unstable in energy absorption, poor in multi-angle impact adaptability, discontinuous, low in efficiency and the like.

Description

technical field [0001] The invention relates to the field of automobile passive safety protection, in particular to an efficient and stable energy-absorbing automobile collision energy-absorbing box. Background technique [0002] In today's society, the automobile industry continues to develop and has become one of the important pillar industries for the development of the national economy, and the per capita share has also increased significantly. As an essential tool for citizens to travel, cars have become an indispensable means of transportation. However, due to the rapid increase in the number of cars, environmental and safety issues have also emerged, and frequent traffic accidents have brought huge losses to human beings and threatened the safety of human life and property. Therefore, reducing the losses caused by safety accidents and environmental problems has become a major problem in today's world, and it has attracted more and more attention. When a car collides...
