Abstract
A kind of device reducing head-on crash B column acceleration, problem to be solved in the utility model is how to reduce B column acceleration.The technical solution of the utility model is that the side of lower beam is welded with lower stringer, rectangle energy-absorption box is provided with above lower stringer, the end of rectangle energy-absorption box is provided with the crossbeam with compression box structure, and one end of rectangle energy-absorption box is fixed on A column, and A column top is provided with firewall；A circle DC01 seam weld material is provided on crossbeam with compression box structure.The utility model has the advantages that: it is based on CAE collision simulation technology, on the basis of head-on crash baseline results, optimize the crossbeam of a newly-increased length 900mm connection energy-absorption box, its two sides is the compression box structure with cross section, increase the energy absorption ability under same special case with this, promotes the score of head-on crash.Added parts structure is simple, and craftsmanship is easily achieved, and mounting means is simple, tries out the advantages that range is wide.
Description
Technical field
The utility model belongs to collision of motor vehicle simulation technical field, specifically a kind of reduction head-on crash B column
The device of acceleration.
Background technique
Automotive safety problem is national governments, society and major automobile always along with the development of auto industry
One of manufactory's focus of attention.For the passive security performance for ensureing the personnel safety in traffic accident, improving automobile, each international politics
Mansion and industry organization have formulated stringent automotive safety regulation and appraisement system.These regulations and appraisement system be not only examine,
The important evidence of automotive SBC energy is evaluated, and provides research direction for vehicle passive safety design.Head-on crash
As the main forms of collision in motor traffic accidents and regulation evaluation, have become the important mesh of car passive safety design
One of mark.
During 50kph head-on crash, since biggish collision energy can only absorb a part by automotive front end structure,
Another part energy acts on remaining and deforms at lesser vehicle body, while in driver and being multiplied with certain acceleration percussion
With member, and in order to allow driver and occupant to experience lesser impact, be less damaging, in vehicle body design it is necessary to
Reasonable Arrangement endergonic structure guarantees that most of collision energy can be absorbed in preliminary stage.
Problem to be solved in the utility model is how to reduce B column acceleration.
Summary of the invention
The purpose of the utility model is to provide a kind of devices for reducing head-on crash B column acceleration.
The purpose of this utility model is achieved in that the side of lower beam is welded with lower stringer, sets above lower stringer
It is equipped with rectangle energy-absorption box, the end of rectangle energy-absorption box is provided with the crossbeam with compression box structure, and one end of rectangle energy-absorption box is fixed
On A column, A column top is provided with firewall；A circle DC01 seam weld material is provided on crossbeam with compression box structure.
The utility model has the advantages that: it is based on CAE collision simulation technology, on the basis of head-on crash baseline results, optimization
The crossbeam of a newly-increased length 900mm connection energy-absorption box, two sides are the compression box structures with cross section, same to increase with this
Energy absorption ability under equal special cases, promotes the score of head-on crash.Added parts structure is simple, and craftsmanship is easily achieved, peace
Dress mode is simple, tries out the advantages that range is wide.
Detailed description of the invention
Fig. 1 is side structure isometric view；
Fig. 2 is the crossbeam schematic diagram with compression box structure；
The utility model is described in further detail by example below in conjunction with attached drawing, but following examples is only
The utility model example therein, does not represent rights protection scope defined by the utility model, the utility model
Rights protection scope is subject to claims.
Specific embodiment
Example 1
The side of lower beam 1 is welded with lower stringer 6, and rectangle energy-absorption box 5 is provided with above lower stringer, rectangle energy-absorption box
End is provided with the crossbeam 2 with compression box structure, and one end of rectangle energy-absorption box is fixed on A column 4, and A column top is provided with fire prevention
Wall 3；A circle DC01 seam weld material 7 is provided on crossbeam with compression box structure.It has properly increased Chinese herbaceous peony end endergonic structure
Intensity, it is therefore an objective to which in limited compression space, more collision energies are can be absorbed in structure, reduce the energy for being transmitted to crew module
Amount, and then left and right sides B column acceleration is reduced, the score of head-on crash is promoted, thus C-NCAP the or E-NCAP star got well.
Based on original 50kph head-on crash B column acceleration larger base, in the left and right sides, the front end of energy-absorption box 5 increases
One length 900mm connection energy-absorption box and crossbeam with compression box structure increase energy absorption ability, such as Fig. 2, which can protect
Card is in collision initial stage energy-absorbing more energy.
Connection type uses seam weld, and such as Fig. 2 makes a call to a circle seam weld in 7 outer boundary position respectively, this part material is DC01,
With a thickness of 1CM, process is relatively simple.In conclusion realizing the purpose of this utility model.
