Description
Technical field
The utility model relates to a kind of automotive floor panel structure, and especially a kind of automotive floor panel that improves automobile front floor and rear floor lap position rigidity is strengthened structure.
Background technology
Along with the raising of life of urban resident level, the popularity rate of vehicle is more and more higher, and the Occupation coefficient of vehicle is also more and more higher, and the incidence of thing followed car accident has also increased than before.The possibility that injures and deaths appear in car accident also constantly increases, and for improving driving safety, also improves simultaneously the rate of surviving of colliding, and will accomplish when driving that outside safety precaution, the safety factor of vehicle self also should cause everybody attention.In the accident that occurs, the probability of side collision is higher, and the rate of causing injury is also larger, and this just requires car body that better safeguard construction design is arranged when side impact, in order to better protect the passenger when collision happens.
Existing car floor are divided into two parts usually, and a part is front floor, and another part is rear floor, adopt the mode of overlap joint to connect between front floor and rear floor.The overlap joint zone on the front floor of some vehicles and rear floor the problem of insufficient rigidity can occur in check analysis.Vehicle is for the arranging exhaust air system, generally the clinch office on plate and rear floor arranges middle passage previously, the middle passage of front floor and rear floor lap-joint tends to deform when side impact occurs, and then make the interior exhaust system of middle passage at this place be squeezed, form larger potential safety hazard.In addition, consider front floor and the middle passage of rear floor lap-joint and the coupling gap requirement of exhaust system, be difficult to satisfy rigidity requirement by the structure of optimizing existing crossbeam.
Summary of the invention
The utility model has solved the defective that can't directly strengthen lap-joint's crossbeam on front floor and rear floor in the prior art, provide a kind of automotive floor panel to strengthen structure, by at middle channel setting deep beam, do not affect exhaust system and arrange, can strengthen front floor and rear floor overlapping part simultaneously.
The middle passage that the utility model has also solved prior art is the defective that potential safety hazard appears in the easy distortion of arranging exhaust air system, provide a kind of automotive floor panel to strengthen structure, by at middle channel setting deep beam, do not affect exhaust system and arrange, the centering passage is strengthened simultaneously.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of automotive floor panel is strengthened structure, comprise front floor and rear floor, front floor be connected the relative side in floor and adopt the fixing mode of overlap joint to connect, be provided with the middle passage that bleeder line is installed on rear floor, vertically be fixed with deep beam near the overlapping part place on middle passage, deep beam is fixed with spacing brace panel towards the surface of middle channel bottom, forms the bleeder line passage between the bottom of spacing brace panel and middle passage.Deep beam and middle channel vertical are fixed, middle passage is parallel with vehicle forward direction, during lateral impact, deep beam centering passage plays booster action, deep beam is when satisfying crossbeam assembly integral intensity, the deflection of passage in when having alleviated side impact is protected exhaust system effectively, has improved safety factor; And deep beam need not the overlap joint beam structure on front floor and rear floor is changed, and both guaranteed the coupling gap requirement of front floor and rear floor overlap joint zone and exhaust chest, guaranteed again the problem of the regional insufficient rigidity of front floor and rear floor overlap joint.
As preferably, the two ends of deep beam span to the both sides of middle passage, the brace panel fixed pan of the centre of deep beam for sinking, the surrounding protuberance of brace panel fixed pan, oppositely turnover again after protuberance, the edge of the dual-side of deep beam is outstanding arcuate structure.The two ends of deep beam are across the both sides of middle passage, and the length of deep beam and the width of middle passage coupling are suitable, do not affect structure and the layout at all the other positions, rear floor; The brace panel fixed pan of deep beam and the protuberance of surrounding make deep beam self have enough rigidity.
As preferably, the end positions of brace panel fixed pan is provided with fixed orifice, fixes by fixed orifice and middle passage both sides.
As preferably, the turnover of the two ends of spacing brace panel has bound edge, bound edge to take the shape of the letter U and encases the end of spacing brace panel.Position between bound edge and bound edge forms an arch configuration, and this arch is just in time suitable with the pipeline of exhaust system.
As preferably, the middle part of spacing brace panel is provided with the reinforcement plane of projection, the surrounding of spacing brace panel and brace panel fixed pan contact, strengthen being provided with mounting hole on the plane, be provided with the sinking blind hole on reinforcement plane between mounting hole, the bottom of blind hole and brace panel fixed pan contact.Blind hole is given and is strengthened the plane to support, and improves the rigidity of strengthening the plane.
As preferably, the dual-side of spacing brace panel is provided with chimb and the concave edge of segmentation, and chimb and concave edge interval are separately.
As preferably, the length of spacing brace panel is less than the length of deep beam, and the length of spacing brace panel and the width of middle passage are suitable.
The beneficial effects of the utility model are: deep beam when satisfying crossbeam assembly integral intensity, when having alleviated side impact in the deflection of passage, effectively protect exhaust system, improved safety factor; Need not the overlap joint beam structure on front floor and rear floor is changed.
