Abstract
The utility model relates to a floor longitudinal beam structure for solving the problems that the structure design of existing longitudinal beam is unreasonable, the section height of the beam-type structure is low and the strength and bending performance thereof are bad, and life safety of the driver is greatly threatened due to the serious deformation of door and deformation and bending of the floor and seat beam when the whole car is crashed from side. The utility model comprises a floor longitudinal beam, a reinforcing plate is fixedly connected to the floor longitudinal beam; multiple reinforced bars are arranged on the floor longitudinal beam; multiple mounting holes are arranged on two sides of the reinforced bars. The floor longitudinal beam structure not only can improve the structure strength and the bending performance but also can satisfy the requirements of side crash safety performance of vehicle via the way of adding the reinforcing plate and the reinforced bars in the floor longitudinal beam, without adding the welding clamp and largely changing the punching die.
Description
Technical field
The utility model relates to a kind of automobile longitudinal girder structure, particularly a kind of longitudinal floor beam structure.
Background technology
The longitudinal floor beam structure is the important component part of vehicle structure, and designing complete longitudinal floor beam structure needs to bear huge impact, guarantees the safety performance of automobile with this.The girder work design of existing part is unreasonable, and the depth of section of girder structure is lower, and intensity and buckling performance are relatively poor, car load is when side collision, threshold can be out of shape seriously, and floor and seat crossbeam exist distortion and bending phenomenon, serious threat driver's life security.
Chinese patent notification number CN 201165252, December 17 2008 day for announcing, but announced a kind of automobile longitudinal girder structure of energy-absorbing, comprise the anterior body of longeron, the blanked part of connecting panel and stringer sides cover board body formation one is affixed before the longeron of anterior body of described longeron and setting, protect the crossbeam adapter plate before the end of the anterior body of connecting panel and longeron is connected with before the longeron, protect the crossbeam adapter plate before described, connecting panel and stringer sides cover board body form the cavity that an osed top runs through along its length before the anterior body of longeron, the longeron.It is too thin that but such structure still seems for side collision, is easy to occur threshold and can be out of shape seriously, and left front floor and seat crossbeam exist distortion and bending phenomenon.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art; provide a kind of girder work reasonable in design; the depth of section of girder structure is higher; intensity and buckling performance are better; when side collision; threshold can not be out of shape seriously, and floor and seat crossbeam do not exist distortion and bending phenomenon, can protect the longitudinal floor beam structure of driver's life security.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of longitudinal floor beam structure, comprise longitudinal floor beam, be fixedly connected with brace panel on the described longitudinal floor beam, described longitudinal floor beam is provided with some reinforced ribs, and the both sides of described reinforced rib are respectively arranged with some mounting holes.Be fixedly connected with brace panel on the longitudinal floor beam, the longitudinal floor beam middle part is provided with some reinforced ribs, by such setting, has improved the structural strength of longitudinal floor beam, has reduced the personal property damage that may cause when collision case takes place; The both sides of reinforced rib are respectively arranged with some mounting holes, and such setting meets the installation situation of existing vehicle, and diel is changed less, has reduced the change cost.
As preferably, the both sides of described longitudinal floor beam are provided with flange, and described longitudinal floor beam integral body is " U " font.The both sides of longitudinal floor beam are provided with flange, and longitudinal floor beam integral body is " U " font, and such structure can make that longitudinal floor beam structural strength and buckling performance are better so that the depth of section of longitudinal floor beam is higher.
As preferably, the flange height of described longitudinal floor beam is greater than half of longitudinal floor beam width.The flange height of longitudinal floor beam has guaranteed that greater than half of longitudinal floor beam width the buckling performance of longitudinal floor beam is better, and in side collision, the situation that bending occurs reduces greatly.
As preferably, the reinforced rib that is provided with on the described longitudinal floor beam amounts to three, and described reinforced rib is parallel to each other, and described reinforced rib is parallel with the flange of longitudinal floor beam.The reinforced rib that is provided with on the longitudinal floor beam amounts to three, and reinforced rib is parallel to each other, and the parallel such setting with the flange of longitudinal floor beam of reinforced rib has strengthened the structural strength of longitudinal floor beam greatly, in side collision, has reduced the possibility that longitudinal floor beam is out of shape.
As preferably, the width of described brace panel equals the width of longitudinal floor beam.The width of brace panel equals the width on longitudinal floor beam base, and brace panel can be fixed together with longitudinal floor beam easily, has kept the unanimity of shape, and the structural strength of longitudinal floor beam everywhere has all obtained generally strengthening.
The beneficial effects of the utility model are: the utility model is by increasing structural development measures such as longeron depth of section, newly-increased longeron brace panel, change under the less prerequisite not increasing welding jig, diel, by adding brace panel and the mode of reinforced rib being set at longitudinal floor beam middle part, improve structural strength and buckling performance, satisfied the side face collision safety performance demands of vehicle.

The specific embodiment
Below by specific embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment:
A kind of longitudinal floor beam structure (referring to accompanying drawing 1), comprise longitudinal floor beam 5, the bilateral symmetry of longitudinal floor beam 5 is provided with flange 1, the height of flange 1 is 49.5mm, longitudinal floor beam integral body is " U " font, be welded with brace panel 4(on the longitudinal floor beam 5 referring to accompanying drawing 2 and accompanying drawing 3), the width of brace panel 4 equates with the width of longitudinal floor beam 5, the front and rear of longitudinal floor beam 5 is provided with mounting hole 3, and the middle part of longitudinal floor beam 5 is vertically arranged with reinforced rib 2, and reinforced rib 2 has three altogether, reinforced rib 2 be parallel to each other and adjacent reinforced rib 2 between distance equate, reinforced rib 2 is parallel with flange 1, and the cross-sectional plane semicircular in shape of reinforced rib 2, the degree of depth of reinforced rib 2 are 7mm.
The longitudinal floor beam two ends were connected with floor frame assembly respectively when the utility model used, the utility model brace panel and reinforced rib play the effect of additional strengthening and buckling performance when collision, danger coefficient when greatly reducing side collision, contrast is not established brace panel and the longitudinal floor beam that groove is induced in crumple is set, when side collision is tested, not establishing brace panel and crumple is set induces the longitudinal floor beam threshold distortion of groove serious, left front floor and seat crossbeam exist distortion and bending phenomenon, and being installed, the utility model advanced simulated crash, brace panel, reinforced rib, the cancellation crumple induces such being provided with of groove to strengthen structural strength of the present utility model, gross distortion does not appear in the flange threshold, increase being provided with of flange and strengthened buckling performance of the present utility model, left front floor and seat crossbeam are for serious deformation and bending phenomenon occurring.
