What can stipulate to be made up of high strength material is also soldered to the enhancement Layer on plate, as strengthening mechanism or reinforcing mechanisms.But, utilize thickness distribution flexibly sheet billet (continuous variable cross section rolled sheet " TailorRolled Blanks ") be also very suitable, wherein this thickness curve and perhaps also have strength curve by change roll gap obtain.
Or, also can arrange be pressed or ply rolling to the enhancement Layer being formed by high strength material on plate, as structure thicker.
In another embodiment, the reinforcing portion being shaped in plate is set, as strengthening mechanism or reinforcing mechanisms with regard to shape.
The strengthening mechanism of described plate also can be by for example obtaining by hot-cured local hardening.This technique also can be by purpose for adapting to the requirement of different vehicle modification.
Described reinforcing area can be with the processed shaping of form of the U-lag in the horizontal of plate and/or longitudinally and/or rib in this plate.
In order to obtain best rigidity, described U-lag and/or rib can have closure plate.
There is the closure plate of different-thickness and/or intensity by use, can realize the load requirement that is adapted to different vehicle modification.This is very favorable, because allow to produce for the unified base plate of different vehicle modification and realize and adapt to different loads requirement in the course of processing subsequently.
In order to obtain best rigidity, described U-lag is also strengthened with structural foam and/or Plastic Parts.This reinforcement also can be used to adapt to the load requirement of different vehicle modification.
By this reinforced plate of corresponding layout, the structure of this tabular component is very diversified.As long as need, very easily curved part also can be set in member.
Can in vehicle structure, be used to the zones of different of vehicle according to integral type tabular component of the present invention.Base plate can be regarded as main application region, thereby has realized the integration of particularly advantageous load path.But also feasible, this member is used in the sidewall of motorcar body and roof or in end wall regions.
In the time that member of the present invention is used as to base plate, can so select strengthening mechanism and/or the reinforcing mechanisms structure thicker in other words of this plate, that is, can be shouldered by it function of longeron and/or crossbeam.
In the time using this member in car bottom, this plate can longitudinally and/or transversely at least be divided into two parts, for example, after noseplate and one base plate.Obviously alleviated weight compared with conventional solution.
In the accompanying drawings, floor piece is for having exemplified the present invention, wherein:
