Abstract
The utility model provides a biasing crashworthiness's crashproof roof beam structure is improved, includes the front longitudinal of a pair of parallel of preceding floor assembly, the fixed bottom of floor assembly in the front, the front bumper assembly who sets up at the front longitudinal tip, front beam I and the front beam II of setting between the front longitudinal, its technical essential is: lie in the triangle beam who is fixed with isosceles triangle between front bumper assembly and the front beam I on the front longitudinal, triangle beam's apex angle points to front bumper assembly, and the triangle beam base is parallel with front beam I. It has simple structure, crashproof effect and the advantage such as is showing.
Description
Technical field
This utility model relates to automobile manufacturing field, specifically a kind of collision prevention girders structure improving offset collision performance。
Background technology
Along with updating of automotive body structure, the development of vehicle passive safety technology is day by day ripe。After automotive SBC can refer to collision scenario or clash into largely, automobile itself can alleviate visitor to be taken advantage of personnel to injure and loads the ability of cargo damage。In vehicle passive safety technical research, have developed multiple different types of collision prevention girders, for instance aluminium alloy collision prevention girders, steel alloy collision prevention girders etc.。Collision prevention girders is deformed as buffering in collision scenario process, can take advantage of personnel for visitor and load goods offer passive security guarantee。In prior art, at least there are the following problems: for this kind of by producing the deformation collision prevention girders as buffering collision in prior art, will fracture when limit belonging to its deformation quantity reaches attribute own, namely the absorption of the collision prevention girders energy impact for producing in collision process is very limited, energy-absorbing effect is poor, it is impossible to enough meet the requirement of passive security performance during automobile high-speed collision。
Utility model content
The purpose of this utility model is to provide a kind of collision prevention girders structure improving offset collision performance, fundamentally solves the problems referred to above, and it has the advantages such as simple in construction, anti-collision effect be notable。
For achieving the above object, this utility model provides following technical scheme: the collision prevention girders structure of this improvement offset collision performance includes front floor assembly, be fixed on the pair of parallel front longitudinal bottom front floor assembly, the front bumper assembly that is arranged on front longitudinal end, the front beam I being arranged between front longitudinal and front beam II, it is characterized in that: described front longitudinal is fixed with the triangular beam of isosceles triangle between front bumper assembly and front beam I, the drift angle of triangular beam points to front bumper assembly, and triangular beam base is parallel with front beam I。
The beneficial effects of the utility model: increase triangular beam in the middle of front longitudinal, can make right-hand stringer that the deformation of left-hand stringer is played a supporting role, avoid the independent stress deformation of left-hand stringer in collision, from cae analysis and experimental result, triangular beam plays a significant role in offset collision, thus improving the performance of anti-offset collision, after increasing triangular beam, the force structure of longeron is controlled effectively, A post reduces with threshold junction bending deformation, the deformation of longeron is greatly reduced, the amount of being aggressively back into of tire reduces, the rear shifting amount of A post diminishes, the deformation on front floor improves, the upper shifting amount of steering column reduces。
