Abstract
The invention discloses a well-shaped integrated floor beam for a passenger vehicle, and provides an integrated floor beam structure which can improve the side collision resistance of the passenger vehicle, has few parts, and is simple in assembly techninology. The well-shaped integrated floor beam is formed by splicing and welding an upper steel plate and a lower steel plate to form an annular closed cavity section structure. The well-shaped integrated floor beam has the advantages that the structure is simple; the use is safe and convenient; due to the well-shaped arrangement of floor cross beams and floor longitudinal beams, side collision can be transmitted uniformly to improve the shock resistance of the vehicle body and better ensure safety space of a passenger chamber, and the flexural rigidity and the torsional rigidity of the vehicle body can be improved to ensure the comfort feeling of passengers; moreover, the well-shaped floor beam is integrated, so that the processing procedure is reduced, and convenience is brought for the assembly of other parts.
Description
Technical field
The present invention relates to passenger vehicle body structure member, be specially and a kind ofly can improve manned vehicle crash-worthiness, number of parts is few, and assembly technology is slab and girder simply integrally.
Background technology
In China, because level crossing form be take as main in urban highway traffic crossing, side collision contingency occurrence probability is the highest, and the rate of causing injury occupies first, and fatal rate is only second to head-on crash.Automobile side is the weaker position of intensity in car body, and endergonic structure part and deformable space are less, serious threat occupant's safety.The manned vehicle of most all adopts self-supporting body, but the torsional rigidity of its vehicle body and Impact Resisting Capability are lower.For this situation, present most of car productions commercial city adopts the crossbeam of profile complexity at front-row seats place, and reinforcement or the larger steel plate of used thickness are installed, this will inevitably cause complex process, productive costs increases, be unfavorable for producing, and too the structure of complexity also can cause the difficulty of chair mounted, heavy part also can cause the increase of tare and use cost.In addition, too much the welding of sheet metal parts can easily cause that stress is concentrated together, affects the crash-worthiness of vehicle body.
Summary of the invention
Technical matters solved by the invention is to provide integrally plate-girder of a kind of manned vehicle groined type, to solve the shortcoming in above-mentioned background technology.
Technical matters solved by the invention realizes by the following technical solutions:
Manned vehicle groined type is plate-girder integrally, by upper and lower two block plate weldings, be formed by connecting, be combined the cavity cross-section structure that forms annular closed, described floor bearer comprises two crossbeams and two longerons, being groined type arranges, floor is divided into symmetrical six, between floor and floor bearer by being welded together.
Passage in the spatial placement forming in the middle of described two longerons, middle passage is overlapped on longitudinal floor beam by flange; Described longeron by crossbeam be divided into front in latter three sections, not identical according to the geomery of three sections of load and arrangement requirement, leading portion cross-sectional area is larger, back segment cross-sectional area is less.
Two crossbeams of described floor bearer are positioned at the weakness zone that vehicle body side clashes into, and have improved the crashworthiness ability of vehicle body side collision, and both sides crossbeam connects respectively car body left-side threshold and right side wall threshold.
The center section part sub-headend of two longerons of described floor bearer is fixedly connected with the rear end of longitudinal beam front section, and the part rear end, stage casing of longeron is fixedly connected with the front end of longeron back segment, and back segment and the back seat crossbeam of the back segment part of longeron are fixed together.
Beneficial effect: the present invention is simple in structure, safe ready, by the groined type arrangement of floor crossmember and longeron, on the one hand can Transmit evenly side collision force, improve the crash-worthiness of vehicle body, guarantee better crew module's survival space, the arrangement of groined type can improve bending stiffness and the torsional stiffness of vehicle body on the other hand, guarantees occupant's traveling comfort, simultaneously, groined type floor bearer is made of one to formula, can reduces manufacturing procedure, and be conducive to the assembling of miscellaneous part.
Accompanying drawing explanation
Fig. 1 is the structural representation of preferred embodiment of the present invention.
Fig. 2 is the integral structure figure of preferred embodiment of the present invention.
In figure: middle passage 2, groined type floor bearer 3, left-side threshold 4, right side wall threshold 6, floor 7, back seat crossbeam 8.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
Referring to Fig. 1,2 manned vehicle groined type plate-girder integrally, by upper and lower two block plate weldings, be formed by connecting, be combined the cavity cross-section structure that forms annular closed.Floor totally comprises middle passage 2, groined type floor bearer 3, and left-side threshold 4, right side wall threshold 6, floor 7 and back seat crossbeam 8 form.
Wherein, middle passage 2 is in groined type floor bearer 3 midways location, moves towards to change consistent with longitudinal floor beam, and both fit tightly, by the flange of middle passage 2 both sides and the longitudinal floor beam weld together of groined type floor bearer 3.Groined type beam 3 two sections of crossbeam left and right in floor are connected with left-side threshold 4 right side wall thresholds 6 respectively, are fixed together by welding.3 two longitudinal floor beam rear ends of groined type floor bearer are all connected with back seat crossbeam 8, have increased the rigidity of rear floor panel.
Described groined type floor bearer 3 is divided into six by floor 7, and floor is arranged symmetrically with, and is welded on groined type floor bearer.With upper-part, jointly form crew module's bottom construction.
Integrally the cavity cross-sectional structure of plate-girder employing ring seal alleviates structural weight to groined type, Path of Force Transfer is better simultaneously.In side collision, crew module's floor panel structure has played supporting role to side wall structure, groined type body stiffness but also be not easy the unstability that bends when being subject to axial load when integrally plate-girder has not only improved side collision, guarantees occupant's living space thereby improve car body collision non-deformability.In addition, this structural section is simple, and thin-wall part consistency of thickness is easily realized.
More than show and described groundwork of the present invention, principal character and advantage of the present invention.The technical personnel of the industry should be understood; the present invention is not restricted to the described embodiments; that in above-described embodiment and specification sheets, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
