Abstract
The invention discloses an automobile energy absorption box. The automobile energy absorption box comprises an energy absorption box body. The energy absorption box body is made of carbon fiber composite materials and is filled with foam aluminum alloy ingots. According to the automobile energy absorption box, as the energy absorption box body is made of the carbon fiber composite materials, the light weight effect is achieved; compared with a common metal energy absorption box, the weight of the energy absorption box which is filled with the foam aluminum alloy ingots and made of the carbon fiber composite materials is reduced by 25% to 40%, the absorbed energy is 1.5 times to 3 times that of the common metal energy absorption box, the collision energy absorption effect can be accordingly improved, and the light weight effect is achieved.
Description
Technical field
The invention belongs to automotive crash safety technical field, specifically, the present invention relates to a kind of vehicle energy absorption box.
Background technology
For avoiding front side member to be out of shape during automobile generation front slight degree of crash, usually between automobile front protecting crossbeam and front side member, energy-absorption box is installed, when collision impact energy exceedes the energy absorption ability of front bumper, energy-absorption box starts to occur conquassation distortion with absorption portion impact energy, thus avoids impact energy and directly act on front side member and cause it to be out of shape.The energy-absorption box structure generally used at present has predeformation design on its box body, and to improve its energy-absorbing deformation characteristic, but the energy-absorption box adopting sheet metal part to make is higher due to weight, causes lower than energy absorption.
Summary of the invention
The invention provides a kind of vehicle energy absorption box, object improves collision energy-absorbing effect, and have light weight effect.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of vehicle energy absorption box, comprises energy-absorption box box body, and described energy-absorption box box body adopts carbon fiber composite material to make, and is filled with foam aluminium alloy ingot in energy-absorption box box body.
Described energy-absorption box box body is the tubular structure of both ends open, inner hollow.
Described energy-absorption box box body is made up of carbon fiber and thermoplastic base resin.
The cross section of described energy-absorption box box body is polygon, energy-absorption box box body is formed many crest lines.
The inside face of described energy-absorption box box body is equipped with glass layer.
The pore-solids ratio of described foam aluminium alloy ingot is 65% ~ 90%.
One end of described energy-absorption box box body is provided with the front side member butt flange for being connected with automobile front longitudinal beam, and the other end is provided with protects crossbeam butt flange before being connected with front guarantor's crossbeam.
Before described, guarantor's crossbeam butt flange and described front side member butt flange are by carbon fiber and thermoplastic base resin mixed-forming.
Described energy-absorption box box body, the described front wall thickness protecting crossbeam butt flange and described front side member butt flange are 2.8mm ~ 5.0mm.
Vehicle energy absorption box of the present invention, because energy-absorption box box body adopts carbon fiber composite material, achieve light weight effect, the carbon fiber composite material energy-absorption box comparatively plain metal energy-absorption box loss of weight 25% ~ 40% of filled and process aluminium alloy ingots, than 1.5 ~ 3 times that energy absorption is plain metal energy-absorption box, thus collision energy-absorbing effect can be improved, and there is light weight effect.
