Brief description of the drawings
Fig. 1 is a kind of structural representation for automobile B-pillar reinforcing plate with variable cross section that the utility model embodiment provides；
In reference：1- first intervals；2- second intervals；3- 3rd intervals；The sections of 4- the 4th；5- First Transitions area；
The transition regions of 6- second；The transition regions of 7- the 3rd.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The all other embodiment obtained, belong to the scope of the utility model protection.
Referring to Fig. 1, the utility model embodiment provides a kind of automobile B-pillar reinforcing plate with variable cross section, including first interval, the
Two sections, 3rd interval and the 4th section, this four sections are to be that this B column reinforcement plates divide from top to bottom, first interval
Close to the position of head part on corresponding B posts, second interval is corresponded to and corresponded on B posts close to the position of people's chest, 3rd interval on B posts
Close to the position of people belly, the 4th section correspond to the position of close people's basin bone on B posts, the section in this four sections flaring successively.
So design, see it is that the width in section from top to bottom increases successively on the whole, in the event of accident, the invasion of head and chest
The invasion amount given compared with prismatic B posts is measured to be much smaller, and the cross-sectional length of belly is small compared with other sections, easily occurs
Deformation, but seat is had at belly and basin bone to bear the impulsive force of a part, then this B column reinforcement plates reabsorb part energy
Amount, will mitigate impulsive force significantly.Such design causes the rigidity of whole B posts and intensity to obtain rational distribution, can be with
It is light-weighted simultaneously, simplify complexity technique, reduce cost, save resource, and the peace of occupant can be better ensured that
Entirely.
It is specific embodiment below：
Optimize such scheme, referring to Fig. 1, by above-mentioned first interval, second interval, 3rd interval and the 4th section
Section make hat-shaped structure, upper edge lengths are small, and lower edge lengths are big, and can of so getting off successively forms the B posts of flaring successively
Reinforcing plate.Other shapes can certainly be made, as long as the small lower edge lengths of upper edge lengths are big.
Further optimize such scheme, referring to Fig. 1, the length range of the top in the section of first interval is located at 60-
Between 80mm, the length range of the top in the section of second interval is located between 90-110mm, the top in the section of 3rd interval
Length range be located between 90-105mm, the length range of the top in the section of first interval is located between 110-130mm, its
It is real it can be seen that the top in the section of second interval length range with the top in the section of 3rd interval length range difference not
It is more, and the maximum of the length range of the top in the section of 3rd interval also than second interval section top length
The small 5mm of maximum of scope, but on the whole from top to bottom, four sections are in the change gradually increased.These numbers
Value scope is all the best number range obtained in testing several times.Lightweight, and safer requirement can be met.
Further optimize such scheme, Fig. 1, first interval, second interval, 3rd interval and four-range please be participate in
The upper edge lengths in section and the ratio of width are 0.6, thus ratio, then coordinate above-mentioned numerical value to can be obtained by the reinforcement of this B posts
The size of plate.
Further optimize such scheme, Fig. 1 please be participate in, we term it First Transition between first interval and second interval
Area, we term it the second transition region between second interval and 3rd interval, we are referred to as between 3rd interval and the 4th section
For the 3rd transition region, in design, we will make between these three transition regions and seamlessly transit, and not allow the size of their transition poor
It is different too big, it can so avoid reinforcing plate stress concentration.
Further optimize such scheme, Fig. 1 please be participate in, between First Transition area and the second transition region and the second transition
Furniture assembly is equipped between area and the 3rd transition region, these furniture assemblies can facilitate this B column reinforcement plate later stages to apply to vapour
On car B posts.
Further optimize such scheme, Fig. 1 please be participate in, furniture assembly is related to the mounting process in later stage, furniture assembly bag
Some mounting holes and some reinforcements are included, these mounting holes and these reinforcements are all located at the place of three transition region transition, can
To facilitate the mounting process in adaptation later stage.Mounting process also includes the changeover portion of several transition regions being arranged to chamfering.
The utility model embodiment provides a kind of automobile, including vehicle body, and variable cross-section vapour mentioned above is provided with vehicle body
Car B column reinforcement plates, this new automobile B-pillar reinforcing plate with variable cross section mentioned is applied on body of a motor car, improves automobile B-column
Anti-bending strength, vehicle collision resistant energy is improved, ensure that the safety of occupant.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from principle of the present utility model and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
