Abstract
The utility model provides a connection structure of automobile longitudinal beam root and preceding bounding wall belongs to car technical field. It has solved the problem that how to improve passenger cabin structure steadiness. This connection structure of automobile longitudinal beam root and preceding bounding wall includes A post inner panel, preceding bounding wall and longeron root, and preceding bounding wall overlap joint has on the longeron root to the bending section that A post inner panel is crooked on A post inner panel, the upper portion and the preceding bounding wall overlap joint of bending section, and the tip overlap joint of bending section is on A post inner panel, and longeron root, preceding bounding wall and A post inner panel overlap joint are as an organic whole, are formed with the cavity between bending section and the A post inner panel. This overlap joint mode forms a complete energy at the vehicle front end and passes the power route to the ability of bearing collision steadiness and here of passenger cabin structure has been improved.
Description
Technical field
The utility model belongs to automobile technical field, relates to the connection structure of a kind of automobile longitudinal girder root and front panel.
Background technology
Along with customer's improving constantly the pay attention to day by day of automotive safety and collision safety laws and regulations requirement, the safety Design of auto vendor to automobile proposes more and more higher requirement.Vehicle body, as the primary load bearing structure of auto against, should possess by being rationally out of shape the function absorbing collision energy and Dissipative Collisions power, reaches the object alleviating occupant injury.Therefore whether body structure design is reasonable, becomes the key factor affecting automotive crash safety.
In body structure common at present, the overlapping mode of longeron root and front panel is that the border of longeron root is overlapped in front panel, the profile of front panel extends to A post two ends from centre, front panel is an integral structure, brace panel is welded with inside and outside front panel, front wall brace panel in crew module and A post are overlapped with framing member, increase the intensity of this structure.
But, the shortcoming that this structure exists; Namely structure is the structure of overlap joint mutually, the structure of side rail back segment is close not with coordinating of its periphery pieces, there is a large amount of weak links, and overlap joint border is less, adds the error that there is field fabrication, causes the remitted its fury of this structure, in the experiment of car load 40% offset collision, longeron root is comparatively large to the intrusion of front wall, and the distortion of A post is serious, and the structural soundness of crew module is poor.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes the connection structure of a kind of automobile longitudinal girder root and front panel, and the technical matters that the utility model solves how to improve the steadiness of crew module's structure.
The purpose of this utility model realizes by following technical proposal: the connection structure of a kind of automobile longitudinal girder root and front panel, comprise A post inner panel, front panel and longeron root, described front panel is overlapped on A post inner panel, it is characterized in that, described longeron root has the bending section of plate benging in A post, the top of described bending section and front panel overlap, the lapping ends of described bending section is on A post inner panel, described longeron root, front panel and A post inner panel overlap joint is integrated, and is formed with cavity between described bending section and A post inner panel.
Be different from prior art, this connection structure is by changing the structure of longeron root, bending section to A post inner panel direction is set, realize longeron root, front panel, A post inner panel three overlap joint be integrated, make to be formed between longeron root and A post a closed cavity body structure, improve the ability of bearing collision herein; When vehicle occupant compartment is collided, this overlapping mode forms a complete energy Path of Force Transfer at vehicle front, thus improves the steadiness of crew module's structure.
In the connection structure of above-mentioned automobile longitudinal girder root and front panel, described longeron root has flange, and described flange is overlapped on front panel and A post inner panel.Increased the area of contact of longeron root and front panel and A post inner panel by design flange, make to overlap the integrative-structure formed more firm.
In the connection structure of above-mentioned automobile longitudinal girder root and front panel, described longeron root comprises side rail and girder plate, and described side rail and girder plate are spliced to form cavity by welding.Longeron root is spliced to form by side rail and girder plate split, easily manufactured.
In the connection structure of above-mentioned automobile longitudinal girder root and front panel, described side rail adopts tailor welded punch forming, and described side rail leading portion is different with the intensity of back segment.The different structure requirement of strength of side rail leading portion and back segment can be met by the stamping forming mode of tailor welded, make side rail structure can optimization, be conducive to the steadiness that improve crew module's structure.
In the connection structure of above-mentioned automobile longitudinal girder root and front panel, between the knee of described longeron root and the edge of front panel, be overlapped with brace panel.By overlap joint brace panel, strengthen the connection structure of longeron root and front panel further.
Compared with prior art, the connection structure of this automobile longitudinal girder root and front panel has the following advantages: this connection structure is by designing the longeron root with bending section, make longeron root, front panel, A post inner panel three can overlap and be integrated, and make to be formed between longeron root and A post a closed cavity body structure, this overlapping mode forms a complete energy Path of Force Transfer at vehicle front, thus improves steadiness and the ability of bearing collision herein of crew module's structure.
