Abstract
The utility model provides a vehicle side impacting reinforcing structure, which is additionally provided with two sheet-element reinforcing plates at the inner side of a space formed by a door sill inner plate assembly and a side wall inner plate assembly to form an approximate box body. Two respective welding flanges of the two reinforcing plates are welded with the two surfaces of a door sill, and the shape of the flanges abuts with the formset surface of the side wall inner plate. Further, a reinforcing rib is arranged on the reinforcing plate and is in the height direction of a vehicle body. The reinforcing structure has obvious reinforcing action on the strength of a middle post and the door sill when the side impacting strength is slightly insufficient. The utility model has the advantages of simple structure and good manufacturability; the structural relation of other parts needs not changing, and only two reinforcing plates are welded on the door sill and then assembled on the vehicle body together with the door sill; the reinforcing plates have simple structure and low manufacture requirement; the influence on the weight of the vehicle body is small; the increased dimension of the reinforcing plate is small; compared with the cost of increasing the strength of door sill material, the cost is substantially reduced.
Description
Technical field
The utility model belongs to the car body structure technical field, is specifically related to floor and threshold strength enhancing structure partly in the car side impact.
Background technology
Car side impact rules all have strict regulation to caving in of central post (being the B post) and threshold.In order to solve the intensity of central post bottom and threshold connecting bridge, the layout that need make the crossbeam on the floor is near improving requirement on central post position and the material selection to threshold itself.This must cause a large amount of raisings of body making cost, has also increased the complexity of body structure simultaneously.
Summary of the invention
The purpose of this utility model is the deficiency at the prior art existence, a kind of automobile side crash additional strengthening is provided, it can solve the problem of central post threshold place undercapacity, and tare and manufacturing cost are controlled to minimum zone, does not make its structure too complicated again.
Technical solution of the present utility model is: add two sheet spare brace panels at threshold inner panel and inboard, the formed space of side-wall inner-plate assembly, form an approximate box body.Two two faces strengthening plates two welding flange separately and threshold weld, other flange shape and side-wall inner-plate shape face near.
Further, done reinforced rib on brace panel, reinforced rib is along the bodywork height direction, and non-face of weld has certain flange to improve its intensity.
In the side impact process,, local intensity is further strengthened because the box body that the existence of brace panel makes threshold inner panel, side-wall inner-plate always be shaped as is almost stressed jointly.And the reinforced rib on the brace panel has the distortion directional tagging, make this advance like box body when side impact, form a process of successively shrinking degeneration, this deformation process has energy absorption, the suffered impact acceleration of threshold has been lowered in this effect.This structure is the absorbing side impact energy to greatest extent, the central post when reducing collision and the size of caving at threshold position.
The effect of invention: this additional strengthening can have the booster action of obvious reinforcement to the intensity at central post and threshold place when the slight deficiency of side collision strength; Simple in structure, need not change the structural relation at other position; Good manufacturability, only need be in the threshold welding two brace panels, is assembled on the vehicle body together with threshold again and get final product, and brace panel is simple in structure, the manufacturing is less demanding; Little to the tare influence, the brace panel size of increase is little, compares cost with raising threshold strength of material and significantly reduces.
Description of drawings
Fig. 1 is the connection structure of threshold and brace panel.
Fig. 2 is the connection structure of side-wall inner-plate and threshold.
The specific embodiment
The automobile side crash additional strengthening that Fig. 1 and Fig. 2 show includes threshold inner panel 3 and side-wall inner-plate assembly 4.The improvement of this structure is to add two sheet spare brace panels 1,2 in threshold inner panel 3 and inboard, side-wall inner-plate assembly 4 formed space, this space is surrounded an approximate box body, two faces that brace panel 1,2 each has two welding flange and threshold inner panels 3 weld, the inboard shape face of other flange shape and side-wall inner-plate 4 near.On brace panel 1,2, also has reinforced rib 5 in addition along the bodywork height direction.
Claims (2)
1, a kind of automobile side crash additional strengthening includes threshold inner panel (3) and side-wall inner-plate assembly (4); It is characterized in that: add two sheet spare brace panels (1,2) in threshold inner panel (3) and inboard, the formed space of side-wall inner-plate assembly (4), this space is surrounded an approximate box body, two faces that brace panel (1,2) each has two welding flange and threshold inner panels (3) weld, the inboard shape face of other flange shape and side-wall inner-plate (4) near.
2, automobile side crash additional strengthening according to claim 1 is characterized in that: the reinforced rib (5) along the bodywork height direction is arranged on the described brace panel (1,2).
