The utility model discloses a simple structure has practiced thrift preceding floor lower part space, and it provides the space to arrange for the chassis, has optimized carrythrough structure to the NVH spare weight on preceding floor upper portion has been reduced, the cost is reduced.
Description
Technical field
The utility model relates to a kind of automobile front longitudinal beam assembly structure, belongs to car body system parts technical field.
Background technology
Current automobile front longitudinal beam assembly structure main flow is divided into three kinds of forms, a kind of independent front side member assembly, another kind is longeron on the front floor of front side member assembly band, and the third is longeron on the front floor of front side member band, increase front side member floor stringer under front floor, thus form herringbone beam's structure.Wherein, first and second scheme reaches equal performance objective at same money vehicle body, then need larger tangent plane and more material, and weight is large, and design efficiency is low, and fuel economy is bad; And third program reaches equal performance objective at same money vehicle body, take the space of bottom, front floor, it is unfavorable to bring to chassis layout.
Summary of the invention
For above-mentioned weak point of the prior art, the utility model aims to provide a kind of automobile front longitudinal beam assembly structure, its structure is simple, save front floor lower space, arrange for chassis and provide space, optimize force transferring structure, and decrease the NVH part weight on top, front floor, reduce cost.
To achieve these goals, the technical solution of the utility model: a kind of automobile front longitudinal beam assembly structure, it includes front floor and sets firmly longeron on the front floor on top, front floor with this, also be installed with front side member floor stringer on this top, front floor, on this front side member floor stringer one end and described front floor, longeron overlaps and is connected and is integrally formed herringbone beam's structure.
Further, on described front floor, longeron both sides are formed with the first flange downwards, and are connected by this first flange and described front floor welded, and on this front floor, longeron one end is upturned and curved girder construction; Described front side member floor stringer one end is occlusion structure and is snapped in the Curved beam structure of longeron on described front floor, and this front side member floor stringer is connected by longitudinal beam welding on this occlusion structure and described front floor.
Further, described front side member floor stringer both sides are formed with the second flange downwards, described front side member floor stringer has the front side member floor stringer leading portion be connected by described second flange and described front floor welded, and be connected and the front side member floor stringer back segment be connected with longeron on described front floor with this front side member floor stringer leading portion one, arrange in obtuse angle between this front side member floor stringer back segment and described front side member floor stringer leading portion.
Further, on described first flange, the second flange and front floor longeron Curved beam structure on all there is reinforced rib.
Further, on described front side member floor stringer, front floor, longeron all integrally welds punch forming.
Further, described front floor is also connected with front side member back segment assembly, this front side member back segment assembly is relative with longeron on described front floor also linearly to be arranged.
Further, floor cross sill and moment of torsion box before described front floor being also welded to connect.
The beneficial effects of the utility model: structure is simple, by front side member floor stringer being designed plate top form herringbone beam's structure with longeron on front floor previously, save front floor lower space, arrange for chassis and provide space, optimize force transferring structure, and decrease the NVH part weight on top, front floor, reduce cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
The utility model is further described below in conjunction with specific embodiment and accompanying drawing.
One is automobile front longitudinal beam assembly structure as described in Figure 1, it includes front floor 40 and sets firmly longeron 30 on the front floor on top, front floor 40 with this, also be installed with front side member floor stringer 10 on this top, front floor 40, on this front side member floor stringer 10 one end and front floor, longeron 30 overlaps and is connected and is integrally formed herringbone beam's structure.
The utility model structure is simple, by front side member floor stringer 10 being designed plate 40 top form herringbone beam's structure with longeron 30 on front floor previously, save front floor lower space, arrange for chassis and provide space, optimize force transferring structure, and decrease the NVH part weight on top, front floor, reduce cost.
Particularly, on front floor, longeron 30 both sides are formed with the first flange downwards, and to be welded with front floor 40 by this first flange and be connected, and on this front floor, longeron 30 one end is upturned and curved girder construction; Front side member floor stringer 10 one end is occlusion structure and is snapped in the Curved beam structure of longeron 30 on front floor, this front side member floor stringer 10 to be welded with longeron 30 on front floor by this occlusion structure and is connected, and enhances the connection structure intensity between longeron 30 and front side member floor stringer 10 on this front floor.The second flange is formed downwards in front side member floor stringer 10 both sides, front side member floor stringer 10 has and welds by the second flange the front side member floor stringer leading portion be connected with front floor 40, and be connected and the front side member floor stringer back segment be connected with longeron 30 on front floor with this front side member floor stringer leading portion one, arrange in obtuse angle between this front side member floor stringer back segment and front side member floor stringer leading portion.Simultaneously also on the first flange, the second flange and front floor longeron 30 Curved beam structure on all there is reinforced rib.
On front side member floor stringer 10, front floor, longeron 30 all integrally welds punch forming, and manufacture craft is simple, lower cost for material.Plate 40 is also connected with front side member back segment assembly 60 previously, this front side member back segment assembly 60 is relative with longeron 30 on front floor also linearly to be arranged.Plate 40 is also welded to connect front floor cross sill 20 and moment of torsion box 50 previously.
During welding, first will weld longeron 30 weld together on stamping forming front side member floor stringer 10, front floor, then be welded into front floor assembly with front floor 40, last and front side member back segment assembly 60, moment of torsion box 50, front floor cross sill 20 weld together.
Above the technical scheme that the utility model embodiment provides is described in detail, apply specific case herein to set forth the principle of the utility model embodiment and embodiment, the explanation of above embodiment is only applicable to the principle helping to understand the utility model embodiment; Meanwhile, for one of ordinary skill in the art, according to the utility model embodiment, detailed description of the invention and field of application all will change, and in sum, this description should not be construed as restriction of the present utility model.
