Detailed description of the invention
Fig. 2 to Fig. 5 below in conjunction with accompanying drawing is described in further detail one of the present utility model front floor centre gangway.
One of the present utility model front floor centre gangway, please refer to Fig. 2 to Fig. 5, comprise front floor body 1 and brace panel 6, described front floor body 1 comprises front floor level plate body 5 and is positioned at the front floor protrusion plate body 7 protruding upward of described front floor level plate body 5 central authorities, described brace panel 6 is fixed on described front floor and protrudes below plate body 7, the region of arching upward that described front floor level plate body 5 and described front floor are protruded between plate body 7 forms centre gangway 2, and described brace panel 6 and described front floor are protruded on plate body 7 and formed netted reinforced region.Like this, brace panel 6 and the front floor that front floor body 1 protrudes are protruded plate body 7 and are combined and form netted reinforced region, improve the intensity at overall centre gangway 2 place, therefore no longer need cost high and the reinforcement structure of the high strength steel plate that manufacture process requirement is high, under the prerequisite realizing equality strength, common cold-rolling steel can be adopted to replace original high strength steel plate by netted reinforced region, effectively reduce costs, and centre gangway 2 material is consistent with front floor body 1 material, all adopt common cold-rolled steel, be applicable to integral type and split type front floor centre gangway, usage range expands, and manufacturing process is simple, and effectively can improve the bulk strength of the safety zonees such as gearshift.
One of the present utility model front floor centre gangway, please refer to Fig. 2 to Fig. 5, the basis of previously described technical scheme can also be: described netted reinforced region comprises at least one and longitudinally strengthens cavity 8 and at least one laterally strengthens cavity 9 that the described end laterally strengthening chamber is longitudinally strengthened end, chamber with described and is communicated with or intersects.Longitudinally strengthen cavity 8 and add cavity for what formed in X direction, its effect is the intensity for strengthening this region, and laterally strengthening cavity 9 is then formed along Y-direction to strengthen cavity, strengthens the intensity in this region.And both ends are communicated with or intersection could form netted reinforced region, and then ensure that centre gangway 2 all has the bulk strength strengthening the overall front floor centre gangway 2 of structure guarantee on X, Y and Z tri-directions.Further preferred technical scheme be described front floor protrude both sides of the edge, plate body 7 top and both sides of the edge, described brace panel 6 top protrudes along described front floor plate body 7 longitudinal respectively extended have longitudinally strengthen cavity 8.Like this, be at least two and longitudinally strengthen cavity 8, strengthening cavity 8 due to this longitudinal direction is formed in Y-direction and the combination of Z-direction direction by front floor protrusion plate body 7 and brace panel 6, therefore this longitudinal direction reinforcement chamber ensures be subject in external force situation, plate body 7 is protruded on front floor and brace panel 6 has booster action in Y-direction and Z-direction, the longitudinal direction formed is simultaneously strengthened cavity 8 and is absorbed energy, avoids stress to concentrate further, strengthens the intensity in this region.Further preferred technical scheme is protrusion both sides of the edge, plate body 7 top, described front floor is circular arc, both sides of the edge, described brace panel 6 top are linear, described brace panel 6 top surface and described front floor are protruded plate body 7 top surface and are fixed, bottom described brace panel 6 sidewall and described front floor protrude plate body 7 bottom sidewall fix.Plate body 7 is protruded on front floor like this and brace panel 6 structure is simple, and fixes in Y-direction and Z-direction, forms double-decker, improves intensity further, and effectively can improve the intensity in this region of overall front floor centre gangway 2.
One of the present utility model front floor centre gangway, please refer to Fig. 2 to Fig. 5, the basis of previously described technical scheme can also be specifically: the extended protruding bar 10 having at least one to raise up of plate body 7 top cross is protruded on described front floor, the extended recessed rib 11 having at least one recessed down of described brace panel 6 top cross, the quantity of described protruding bar 10 is consistent with the quantity of described recessed rib 11, the position of described protruding bar 10 is corresponding with the position of described recessed rib 11, formed between described protruding bar 10 and described recessed rib 11 and laterally strengthen cavity 9.Like this, form transversely arranged formation multiple laterally reinforcement cavity 9, in the space namely formed between protruding bar 10 and recessed rib 11, have air to exist, when this region, place is subject to external force, cavity structure in this region absorbs external force deformation, avoids stress to concentrate, strengthens Z-direction and Y-direction intensity simultaneously.Arrange protruding bar 10 and recessed rib 11 itself can improve front floor and protrude the intensity of plate body 7 and the intensity of brace panel 6 simultaneously.Preferred technical scheme is that described recessed rib 11 is corresponding with the shape of described protruding bar 10 further.Advantage corresponding to shape is upper and lower symmetry, and when Z-direction is stressed, this structure has stronger intensity, and during torsion, non-deformability is stronger.Further preferred technical scheme is described recessed rib 11 is inverted trapezium structure, and described protruding bar 10 is the trapezium structure just put, and the shape that the transverse direction that described protruding bar 10 and described recessed rib 11 are formed strengthens cavity 9 is hexagon.Hexagonal advantage is that base is wide, and stressed energy dispersion, structural strength is high.Can also be the recessed downwards degree of depth of described recessed rib 11 be 10mm, the height that described protruding bar 10 raises up be 15mm.If both are 10mm, stress is comparatively large, if both are 150mm, then stress can be better, but manufacturability is poor.Preferably protruding 15mm, below recessed 10mm, such stress value is up to standard, and manufacturability is better.
One of the present utility model front floor centre gangway, please refer to Fig. 2 to Fig. 5, and the basis of previously described technical scheme can also be specifically: described front floor is protruded between plate body 7 and brace panel 6 for being welded and fixed.The advantage be welded and fixed is that fixed form is relatively firm, and connection mode is fairly simple, and cost is low, it is little to take up room, and substantially can not additionally take up room.Certainly other modes can also be adopted to fix, fix as used screw bolt and nut or use the modes such as clamping to fix.Can also be that described front floor level plate body 5 protrudes plate body 7 with described front floor and fixes for split type or be formed in one.Namely both can be split type fixing, also can be one-body molded, because centre gangway 2 has the booster action of brace panel 6 and netted reinforced region, it can adopt common cold-rolled steel, both materials can be unified, and split type to be connected and fixed Method compare many also than being easier to, easily manufactured, cost is low.
Above-mentionedly only several specific embodiments in the utility model to be illustrated; but can not as protection domain of the present utility model; every according to the change of the equivalence done by design spirit in the utility model or to modify or equal proportion zooms in or out, all should think and fall into protection domain of the present utility model.
