Description
Technical field
The utility model relates to the auto body field, more particularly relates to a kind of automobile longitudinal girder structure.
Background technology
In today that people more and more pay attention to the safety of car load, the performance of automobile longitudinal girder has crucial effects for the safety that improves car load, when automobile bumped, the rigidity of automobile longitudinal girder and the height of intensity directly affected the deformation extent of car body and to driver and crew's extent of injury.At present, in known art technology, have the technical scheme of the additional strengthening at a kind of vehicle front side member rear portion to be: it goes up horizontal stripe after mainly comprising behind the front side member, one bottom crossband and one, its upper and lower horizontal bar all is U type structure, constitute a closed cross-section together, it is welded on the effect of longeron rear additional strengthening; The technical scheme of another kind of automobile rear longitudinal girder rear portion additional strengthening is: its keystone configuration is to add a U type spare in floor side member inside, does an ellipse around boss in its bottom, welds with the floor side member bottom surface on boss.These two kinds of structures are similar in fact, really can strengthen the longeron rear strength to a certain extent, but it is the same with general structure, all be to improve its rigidity and intensity by the free area that increases longeron, but since structure and material etc. the restriction of aspect, existing automobile longitudinal girder structure still can not reach the target call to rigidity and intensity, makes vehicle easy bending of one-sided longeron when offset collision takes place, thereby cause the car body distortion serious, and driver and crew are damaged.
The utility model content
A kind of automobile longitudinal girder structure of the utility model, its objective is: the automobile longitudinal girder structure that provides a kind of rigidity and intensity obviously to increase, make vehicle when offset collision takes place, the one-sided longeron of vehicle is not easy bending, thereby avoids car body distortion problem serious and that driver and crew are damaged.
In order to address the above problem, the technical scheme that the utility model is taked is:
A kind of automobile longitudinal girder structure comprises: the longeron outer cover plate, the longeron inner cover plate is provided with the ups and downs brace panel that is connected with the longeron outer cover plate in described automobile longitudinal girder inside configuration.
Described ups and downs brace panel is made up of upper strata brace panel and lower floor's brace panel, the recessed place of upper strata brace panel is connected with the high spot of lower floor's brace panel, one side of the close longeron outer cover plate of described upper strata brace panel and lower floor brace panel is connected with the automobile longitudinal girder outer cover plate, and the high spot of described upper strata brace panel is connected with two other face of longeron outer cover plate respectively with the recessed place of lower floor's brace panel.
Described upper strata brace panel and lower floor's brace panel constitute net structure in the automobile longitudinal girder inside configuration, and it is divided into a plurality of triangles and quadrilateral structure with automobile longitudinal girder.
Described brace panel is arranged on the longeron corner, also can be provided with in whole automobile longitudinal girder inside configuration as required.
Between described upper strata brace panel high spot and the recessed place of lower floor's brace panel and the longeron outside plate lid, between the recessed place of upper strata brace panel and the high spot of lower floor's brace panel all by connecting by weld nugget.
The purpose of this utility model is to lay out a kind of simple girder work in limited space, thereby improves the rigidity and the intensity of automobile longitudinal girder.After the utility model adopts technique scheme, the rigidity and the intensity of automobile longitudinal girder are greatly enhanced, thereby make vehicle one-sided longeron when offset collision takes place to bear bigger load and be difficult for bending, thereby alleviate the degree of car body distortion and the degree that driver and crew are injured.
