Description
Technical field
The invention belongs to automotive body structure field, be specifically related to the connection structure of plate behind a kind of automotive rear upright column assembly and rear skirtboard inner panel and rear floor.
Background technology
For micro-car, behind column assembly (being mainly rear column bottom section) and rear skirtboard inner panel and rear floor, the connection structure of plate is larger on the impact of car load twisting property thereafter.
As shown in Figure 1, the connection structure of plate behind the rear column assembly of existing vehicle and rear skirtboard inner panel and rear floor, comprise plate 1 behind rear floor, rear column bottom exterior skin 2, rear skirtboard inner panel 3 and rear column bottom outer skin reinforcement 4, rear column bottom outer skin reinforcement 4 is step, its top has the left flange 41 of bending left, rear skirtboard inner panel 3 is " ┛ " shape, its top has the right flange 31 of bending to the right, behind this right flange 31 and rear floor, plate 1 welds, the bottom end of rear skirtboard inner panel 3 has the lower flange 32 of downward bending, this lower flange 32 welds with the bottom of rear column bottom outer skin reinforcement 4, rear column bottom exterior skin 2 is approximate " 7 " font, behind the upper side of its top flange and rear floor, plate 1 welds, downside and left flange 41 weld, left flange, behind rear floor, the connecting portion of the top flange of plate and rear column bottom exterior skin forms three layers of welding structure, the sidewall of rear column bottom exterior skin 2 and the welding of the sidewall of rear skirtboard inner panel 3, rear column bottom exterior skin 2, rear column bottom outer skin reinforcement 4 and rear skirtboard inner panel 3 form larger fitfull cavity, rear column bottom exterior skin 2, behind rear skirtboard inner panel 3 and rear floor, plate 1 forms minimum fitfull cavity.This connection structure makes car load twisting property not high, in order to promote the intensity of this connection structure, to improve car load twisting property, need to increase skirtboard position die cavity after the material thickness of the single-piece (such as rear column bottom exterior skin, rear column bottom outer skin reinforcement) in rear column assembly or single increase, these two kinds of hoisting way not only can increase bodywork parts weight, and can make the single part moulding degree of depth increase, producting process difficulty is increased.
Summary of the invention
The connection structure that the object of this invention is to provide plate behind a kind of automotive rear upright column assembly and rear skirtboard inner panel and rear floor, not increase from one piece thickness, even alleviates in the situation of from one piece thickness, improves car load twisting property.
The connection structure of plate behind automotive rear upright column assembly of the present invention and rear skirtboard inner panel and rear floor, comprise plate behind rear floor, rear column bottom exterior skin, rear skirtboard inner panel and rear column bottom outer skin reinforcement, described rear column bottom outer skin reinforcement is step, its top has the left flange of bending left, described rear skirtboard inner panel is " ┛ " shape, its top has the right flange of bending to the right, plate welding behind this right flange and rear floor, the bottom end of rear skirtboard inner panel has the lower flange of downward bending, the bottom welding of this lower flange and rear column bottom outer skin reinforcement, described rear column bottom exterior skin is "] " shape, plate welding behind the upper side of its top flange and rear floor, downside and described left flanging welded, left flange, behind rear floor, the connecting portion of the top flange of plate and rear column bottom exterior skin forms three layers of welding structure, the upper portion side wall welding of the upper portion side wall of rear column bottom exterior skin and rear column bottom outer skin reinforcement, the bottom flange of rear column bottom exterior skin and the welding of the bottom surface of rear skirtboard inner panel, rear column bottom exterior skin, rear column bottom outer skin reinforcement and rear skirtboard inner panel form quadrangle die cavity, rear column bottom exterior skin, behind rear skirtboard inner panel and rear floor, plate forms quadrangle die cavity.
Further, in order to optimize power transmission passage, improve the ability that torsion is born in rear column assembly bottom under reverse load, promote fatigue resistance, and while preventing from assembling, there is the interference causing because of part error, the upper portion side wall of described rear column bottom outer skin reinforcement (corresponding to the back side of the face of weld of the upper portion side wall welding of rear column bottom exterior skin) be provided with reinforced rib, this reinforced rib is that the face of weld of described rear column bottom outer skin reinforcement and described lower flanging welded is cambered surface along power transmission direction wide and high gradual change muscle gradually gradually from top to bottom.
The present invention has following effect:
(1) in the present invention, adopt and be "] " the rear column bottom exterior skin of shape, make rear column bottom exterior skin, rear column bottom outer skin reinforcement and rear skirtboard inner panel form quadrangle die cavity, rear column bottom exterior skin, behind rear skirtboard inner panel and rear floor, plate forms quadrangle die cavity, by rear column bottom exterior skin in prior art, the cavity that rear column bottom outer skin reinforcement and rear skirtboard inner panel form is divided into two, form the quadrangle die cavity of two series connection, contrast through cae analysis, connection structure of the present invention has promoted about 30000Nm/rad to car load torsional stiffness, and the material thickness of rear column bottom outer skin reinforcement and rear column bottom exterior skin all can attenuate 0.1～0.2mm, the about 0.3kg of loss of weight.
(2) because the upper portion side wall of rear column bottom outer skin reinforcement is provided with along power transmission direction wide and high gradual change muscle gradually gradually from top to bottom, the upper portion side wall laminating welding of the back side at position, gradual change muscle place and rear column bottom exterior skin, the face of weld of rear column bottom outer skin reinforcement and lower flanging welded is designed to cambered surface; Therefore, divide applied pressure to spread from gradual change muscle from side round part, be delivered to crossbeam position, car rear portion by rear column bottom exterior skin reinforced rib, rear column bottom exterior skin, rear skirtboard inner panel, improve the ability that torsion is born in rear column assembly bottom under reverse load, having promoted the intensity of antifatigue, there is the interference causing because of part error in the cambered surface of the face of weld of rear column bottom outer skin reinforcement and lower flanging welded design simultaneously while also having prevented assembling.
