Abstract
The invention relates to a vehicle energy absorption box which has better anti-collision effect. The vehicle energy absorption box is provided with an energy absorption box body with two openings at both ends. The vehicle energy absorption box is characterized in that the vehicle energy absorption box body is arranged in a step shape along the longitudinal direction of a vehicle body.
Description
Technical field
The present invention relates to a kind of vehicle energy absorption box.
Background technology
In the prior art, as denomination of invention is " a kind of automobile accessory frame energy-absorbing box " patent (patent No.: 200620075281.8) disclosed technical scheme, most vehicles all adopt the energy-absorbing box of inside and outside plate weld together and both ends open, the energy-absorbing box is connected with automobile longitudinal girder with front bumper, be used to prevent the occupant is damaged when automobile from bumping, existing energy-absorbing box anticollision effect is not ideal enough.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of vehicle energy absorption box, has better anticollision effect.
Realize the technical scheme of objects of the present invention:
A kind of vehicle energy absorption box has the energy-absorbing box body of both ends open, and it is characterized in that: the energy-absorbing box body is vertically stepped along vehicle body.
It is stepped that the energy-absorbing box body vertically is the 1-5 level along vehicle body.
The energy-absorbing box body be connected to be used for the automobile front beam bonded assembly before connecting panel and be used for automobile front side member bonded assembly after connecting panel.
The energy-absorbing box body adopts seamless hollow square steel pipe roller extrusion forming.
The beneficial effect that the present invention has:
Energy-absorbing box body of the present invention adopts step structure, and easier conquassation distortion fully absorbs energy, avoids the occupant is damaged, and can also make vehicle body guarantee certain intensity and rigidity simultaneously.And the present invention adopts integral structure can effectively reduce manufacturing cost.
