Abstract
The invention relates to a car member and particularly relates to a car side wall frame. The car side wall frame comprises a side wall frame inner plate and a side wall frame outer plate which are one-step hot stamping formed steel plates, and the outside of the side wall frame inner plate is in butt connection and fix with the corresponding outside of the side wall frame outer plate. According to the car side wall frame, the side wall frame inner plate and the side wall frame outer plate are one-step formed parts, so that the force transmission effect of the formed integral side wall frame assembly is better than that of a traditional side wall assembly formed by spot welding splicing of a plurality of stamping parts. The side wall frame inner plate and the side wall frame outer plate are integrated in a edge-to-edge laser full welding mode, so that welding weaknesses are reduced, and even the material strength at the welding position is higher than the strength of the base materials; the side wall frame inner plate and the side wall frame outer plate are integrated in a edge-to-edge laser full welding mode, so that welding flanges are not required to be designed, usage of materials is reduced, the component mass is reduced, and great help is provided for improvement of the fuel economy.
Description
Technical field
The present invention relates to a kind of automobile component, be specially a kind of car side wall skeleton.
Background technology
Tradition car side wall skeleton be divided into front in latter three sections, the form by welding between each section is fixed into an integral body.The parts of tradition side wall frame assembly all obtain steel component in cold stamping mode, and the formation of traditional side wall frame assembly need to accumulate all part production tolerances, welding tolerance, and existing deficiency is:
1) amount of parts is many, and the attendant equipments such as corresponding mould, cubing, fixture are more, processing and fabricating difficulty, and productive costs is high.
2) structural strength is poor, can affect the crash survivability of car load.
3) can cause the weight of whole gusset heavier, be unfavorable for the raising of fuel economy.
Summary of the invention
The object of the invention is to, for the deficiencies in the prior art, provide a kind of car side wall skeleton, intensity is high, and crash survivability is high, and processing and manufacturing is simple.
Technical scheme of the present invention is, a kind of car side wall skeleton, comprise side wall frame inner panel and side wall frame outside plate, and side wall frame inner panel and side wall frame outside plate be the stamping forming steel plate of disposable thermal, and the outside of side wall frame inner panel is fixing with the corresponding outside docking of side wall frame outside plate.
Side wall frame inner panel docks fixing mode with the corresponding sides of side wall frame outside plate be laser welding, forms the continual welding edge of a whole circle.
Side wall frame of the present invention consists of the stamping forming steel plate of disposable thermal, inner and outer plates all adopts one-piece construction, adopt high strength steel plate material, and in conjunction with advanced heat stamping and shaping technology, can improve the drawing property molding effect of material, recycle advanced laser welding technology and weld, guarantee the intensity of side wall frame assembly, improve the crash survivability of car load.All contact edges are all fixed by laser welding, and to reach the welding effect of laser full weld, although be assembly, integral rigidity and intensity are all very good.
Side wall frame inner panel and side wall frame outside plate in the present invention are one-shot forming part, and the power transmission effect and the bulk strength that form integral type gusset frame assembly are better than the traditional side wall assembly being spliced by a plurality of blanked part spot welding; Side wall frame inner panel and side wall frame outside plate, with edge-to-edge's laser full weld together, reduced and welded weak appearance, and the strength of material of commissure even may be higher than the intensity of mother metal; Side wall frame inner panel and side wall frame outside plate, with edge-to-edge's laser full weld together, without design welding flange, reduced the use of material, alleviated the quality of assembly, and the raising of fuel economy is had very great help; In prismatic situation, the cavity wall thickness of one-piece side closed structure is even, and structural strength and flexion torsion mode are all better than traditional type side wall structure; Integral type gusset skeleton has two parts to form, and has reduced the quantity of part, is conducive to improve allowance control precision, machine automatization rate, reduces the input of the attendant equipments such as production site, mould, cubing, fixture.
Accompanying drawing explanation
Fig. 1 is the structural representation of side wall frame of the present invention;
Fig. 2 is the structural representation of side wall frame outside plate in Fig. 1;
Fig. 3 is A-A welded section figure in Fig. 2.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of car side wall skeleton, comprise side wall frame inner panel 1 and side wall frame outside plate 3, and side wall frame inner panel 1 and side wall frame outside plate 2 are the stamping forming steel plate of disposable thermal, and the outside of side wall frame inner panel 1 is fixing with the corresponding outside docking of side wall frame outside plate 2, and side wall frame inner panel 1 docks fixing mode with the corresponding sides of side wall frame outside plate 2 be laser welding.
Side wall frame inner panel 1 docks fixing mode with the corresponding sides of side wall frame outside plate 2 be laser welding, forms the continual welding edge of a whole circle, and the shape of weld seam 5 as shown in Figure 3.
