Inverse conical honeycomb type automobile bumper support structure

Abstract

The invention discloses an inverse conical honeycomb type automobile bumper support structure. The support structure comprises a cross bar, a honeycomb force bearing structure and a front board which are assembled and connected together sequentially, wherein the honeycomb force bearing structure comprises a plurality of conical tube units arranged in array, the array-shaped conical tube units constituting the force bearing structure are tightly distributed from the bumper to the front board, the front board is assembled and connected together with an automobile housing, and the cross bar is assembled and connected together with an energy absorption box of an automobile; each conical tube unit comprises an outer cone frustum tube and an inner cone frustum tube which are integrally connected, and the larger end surface of the outer cone frustum tube faces the cross bar. The inverse conical honeycomb type automobile bumper support structure has good shock resistance, is good in overall energy absorption effect, high in bending resistance, safe, reliable and high in stability and has better light weight effect.

Description

technical field [0001] The invention relates to a buffer support structure, in particular to an inverse tapered honeycomb automobile bumper support structure. Background technique [0002] With the progress of society, the number of automobiles has increased, and the anti-collision and energy absorption requirements for collision safety accidents during the driving process of automobiles are also getting higher and higher. In order to absorb the energy of the collision during a car collision, most cars will be equipped with bumpers. In the prior art, the bumper of an automobile is mainly composed of a beam, a horizontal bar and a hollow thin-walled tube buffer structure. The hollow thin-walled tube buffer structure is arranged between the metal beam and the metal bar. The hollow thin-walled tube buffer structure generally consists of Simple structure of aluminum round tube or square tube. The hollow thin-walled tube is used as the main energy-absorbing device in the bumper...

AI Technical Summary

Problems solved by technology

The hollow thin-walled tube is used as the main energy-absorbing device in the bumper, but the hollow thin-walled tube on the bumper in the prior art is simply installed in parallel, so that the bumper can play a better role in the process of frontal collision. However, it does not perform well in oblique collisions under multiple impact conditions, which makes the energy absorption effect of the hollow thin-walled tube buffer structure of the automobile bumper limited, which in turn causes the overall energy absorption effect of the automobile bumper to be poor. Or indirectly affect the safety of the car and its members
