Description
Technical field
The present invention relates to a kind of floor beam structure of automobile, especially a kind of self-supporting body floor bearer assembly structure, belongs to automobile technical field.
Background technology
The advantages such as automotive body structure can be divided into bearing-type, Non-carrying type and semi-integral body three types, and wherein self-supporting body can alleviate complete vehicle quality with it, little to interior spacial influence, floor level is low, smooth ride, HOP ON–HOP OFF, economic performance are good become the first-selection of car body structure.Because self-supporting body does not have rigid-frame, it is taken advantage of except it is intrinsic and carries except function, also directly will bear the effect of various load forces.Particularly when collision happens accident, self-supporting body need ensure the safety of occupant by the mode such as energy-absorbing, crumple.
Current self-supporting body floor bearer assembly generally comprises longeron, front anti-collision beam, intermediate transverse girder and back buffer beam, wherein longeron is symmetrically arranged, they are front and back breakthrough status, and front anti-collision beam, back buffer beam are fixed on longeron rear and front end, arrange some crossbeams in longeron middle part.Above-mentioned floor bearer assembly structure is before vehicle occurs during (or rear) collision case, collision impact energy passes to longeron after being partially absorbed by front anti-collision beam (or after cross member), whole bodywork component is passed in (or front) side backward again by longeron, because each component of floor bearer assembly is in mutual vertical confined state, collision energy transmission apart from short, can not be fully absorbed, the grievous injury to occupant and vehicle can be caused.
For solving the problem, application number be 201210497119.5 Chinese patent application file disclose a kind of Automotive floor bearer and there is the automotive floor panel of this Automotive floor bearer, as shown in Figure 1, this patent application technical scheme relates to self-supporting body, wherein Automotive floor bearer comprises symmetrically arranged two longerons 20, described longeron is along the length direction longitudinal extension of automotive floor panel, two root longerons 30 are also symmetrically arranged with between two longerons, described sub-longeron is along the length direction longitudinal extension of automotive floor panel, adjacent longeron is connected by tie-beam 40 in front end with sub-longeron.Although this patent application technical scheme solves existing Automotive floor bearer when crashing to the problem that occupant safety protective capability is poor; but which increase two root longerons 30, bring that vehicle floor beam assembly amount of parts is many, quality is large, be unfavorable for the problems such as chassis layout.
Summary of the invention
The object of the invention is to the drawback for prior art, the Automotive floor bearer assembly that a kind of structure is simple, amount of parts is few, be convenient to entire vehicle layout, can strengthen vehicle resistance collision energy is provided.
Problem of the present invention realizes with following technical proposals:
A kind of Automotive floor bearer assembly, it comprises front anti-collision beam, front guide beam, front side ladder-shaped frame, rear side ladder-shaped frame, rear guide beam and back buffer beam, described front anti-collision beam and front guide beam front end are assembled, described front guide beam rear end is fixedly connected with front side ladder-shaped frame, described front side ladder-shaped frame and rear side ladder-shaped frame are the trapezium structure of integral type, described rear side ladder-shaped frame is fixedly connected with rear guide beam front end, and described rear guide beam rear end and back buffer beam assemble.
Above-mentioned Automotive floor bearer assembly, described front side ladder-shaped frame and rear side ladder-shaped frame are connected as a single entity by intermediate transverse girder.
Above-mentioned Automotive floor bearer assembly, described front guide beam is symmetrically arranged, and is provided with front anti-collision beam crumple endergonic structure in front guide beam and front anti-collision beam rigging position place.
Above-mentioned Automotive floor bearer assembly, described rear guide beam is symmetrically arranged, and is provided with back buffer beam crumple endergonic structure in rear guide beam and back buffer beam rigging position place.
Above-mentioned Automotive floor bearer assembly, it also comprises side threshold beam, and described side threshold beam is symmetrically arranged, and they are fixedly assemblied in the two ends of intermediate transverse girder.
The present invention arranges front and back double trapezoid framed structure in Automotive floor bearer assembly, not only ensure that the stability that vehicle floor beam power is transmitted; And when collision happens accident, by front side ladder-shaped frame and rear side ladder-shaped frame, collision energy is passed to both sides sill strip more, decreases the distortion of crew module, thus alleviate the injury to occupant; Meanwhile, in ladder-shaped frame structure and existing Automotive floor bearer assembly, longitudinal and transverse beam is arranged vertically structure comparison, energy transferring path lengthens, can absorb collision energy more fully.And the parallel force transferring structure of traditional through beam, when collision happens accident, most of collision energy is passed to the middle part of vehicle body, absorbs energy by the deformation of member in the middle part of vehicle body, more weak to passenger protection ability; Although the floor beam structure of automobile adding sub-longeron by sub-longeron to transmit decomposition collision energy, decrease the blastic deformation amount in the middle part of vehicle body, but its sub-girder work can be arranged chassis and bring adverse effect, structure of the present invention is simple as can be seen here, amount of parts is few, it had both been convenient to entire vehicle layout, significantly enhanced again the ability that collision resisted by vehicle.
