Energy absorption standard part, front longitudinal beam and manufacturing method of energy absorption standard part

Abstract

The invention provides an energy absorption standard part. The energy absorption standard part comprises a lower plate and an upper plate, wherein the lower plate is made of one-way non-woven carbon fiber cloth and used for achieving one-way energy transmission, and the upper plate is made of one-way non-woven carbon fiber cloth and used for achieving one-way energy transmission; middle structureswhich are formed by winding and curing orthogonal carbon fiber woven cloth and achieve energy transmission in the three-dimensional direction, wherein the number of the middle structures is at leastone, and each middle structure is in a hollow pipe shape; the radial direction of each intermediate structure is consistent with the length directions of the lower plate and the upper plate, and eachintermediate structure is fixed between the lower plate and the upper plate, so the lower plate, the upper plate and the intermediate structures form a common energy transfer channel for dispersing external energy. By means of the energy absorption standard part, the problems that in the prior art, an energy absorption standard part is unstable in crumple process, insufficient in crumple and insufficient in energy absorption can be solved, and the requirements of front longitudinal beams, front cross beams, B columns and the like of most vehicle types can be met.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an energy-absorbing standard part, a front longitudinal beam and a manufacturing method of the energy-absorbing standard part. Background technique [0002] The front longitudinal beam is an energy-absorbing structure located on both sides under the engine, which is equivalent to the body frame. When a car collides, the front side beam absorbs the impact energy to a certain extent through its own crushing and deformation, and then transmits the remaining impact energy to the passenger compartment of the body. Therefore, in the process of a car collision, if the structure of the front longitudinal beam changes suddenly, it will cause a large change in the instantaneous acceleration, which will endanger the life safety of the car occupants. [0003] Among all body parts, the front side beam absorbs the most collision energy, and its energy absorption characteristics and deform...
