Description
Technical field
The present invention relates to body of a motor car field, more specifically relate to the reinforcing structure on a kind of through automobile dash board and front floor.
Background technology
Safety performance is more and more focused in the exploitation of current new model, and front deck and front floor connecting zone connectivity quality directly affects just to touch and be biased touches performance. Such as CN201220282124.X disclosed " supporting structure of a kind of front panel " and CN200820176323.6 disclosed " vehicle body front panel reinforcing structure always becomes with vehicle body front panel ", in prior art, the reinforcing structure of front panel all lays particular emphasis on front panel local strengthening, its stiffening effect is general, the lifting effect of collision performance is not obvious, in addition it is also necessary to strengthen further.
Summary of the invention
It is an object of the invention to provide a kind of automobile dash board and the reinforcing structure on front floor, transmit path to improve by power, promote vehicle body anticollision performance, solve and just touching and be biased when touching, the distortion of front panel and the excessive problem of intrusion volume.
The reinforcing structure on automobile dash board of the present invention and front floor, comprise and being arranged symmetrically and left reinforcement framework that structure is identical and right reinforcing structure, left reinforcing structure comprises front panel left support plate, the left deep beam of front panel and the left curb girder front part of nacelle, the left deep beam of front panel is welded in front panel, and its right-hand member curb girder front part left with nacelle welds; What the front end of front panel left support plate was overlapped on the left deep beam of front panel curb girder front part left with nacelle welds place, and curb girder front part left with nacelle and the left deep beam of front panel weld respectively; Being welded in front panel in the middle part of front panel left support plate, stiffener leading section left with front floor, its rear end is welded, and with front floor welded in the middle part of the left stiffener in front floor, its rear end and front-row seats install front cross beam welding.
Right reinforcing structure comprises front panel right support plate, the right deep beam of front panel and the right curb girder front part of nacelle, and the right deep beam of front panel is welded in front panel, and its left end curb girder front part right with nacelle welds; What the front end of front panel right support plate was overlapped on the right deep beam of front panel curb girder front part right with nacelle welds place, and curb girder front part right with nacelle and the right deep beam of front panel weld respectively;Front panel right support plate is welded in front panel, and stiffener leading section right with front floor, its rear end is welded, and with front floor welded in the middle part of the right stiffener in front floor, its rear end and front-row seats install front cross beam welding.
Front panel left support plate is semi-enclosed box shape, welds with front panel side in the middle part of front panel left support plate, and the position that this welding position is welded on another side of front panel with section after the beam of the nacelle left side is corresponding; Front panel right support plate is semi-enclosed box shape, welds with front panel side in the middle part of front panel right support plate, and the position that this welding position is welded on another side of front panel with section after beam on the right of nacelle is corresponding, to strengthen the structural strength of this reinforcing structure further.
The reinforcing structure on automobile dash board of the present invention and front floor, front panel back up pad and front floor reinforcement form through front panel and the reinforcing structure on front floor. Front panel deep beam welds with engine nacelle curb girder front part, and what the front end overlapping welding of front panel back up pad was connected on front panel deep beam and engine nacelle curb girder front part welds place, effectively absorbs from front collision and offset collision energy. Front floor reinforcement rear end and front-row seats install front cross beam welding, it is achieved that be connected with vehicle body framework construction, and part overlap joint rationally, transmits path by power good. This structure makes the collision-deformed weak region of front panel and front floor form through reinforcing structure, is connected with vehicle body skeleton well, effectively improves vehicle body anticollision performance.
