Abstract
The utility model discloses a vehicle middle-column main reinforced plate structure, with features of simple structure, firm strength, flat surface, small number and light quality. The middle-column main reinforced plate is made of steel plates of different thicknesses and the thickness of each steel plate is selected according to the strength to lightweight the parts. The steel plates of different thicknesses are welded into one piece of steel plate and then pressed into whole finished-product parts. The welding way is a laser welding way using butt-welding way. The whole surface is ensured to be flattened and the welding seam is ensured to be flattened and the welding is reliable and connection is firm. The number of the parts is small, the weight is light and the processing amount is reduced.
Description
Technical field
The utility model relates to the main brace panel structure of automobile center pillar, and the lightweight that more particularly relates to automobile center pillar master brace panel structure constitutes.
Background technology
In the existing automobile center pillar master brace panel structure, generally select one of following two kinds of forms for use: first kind of form is the integral structure that is formed by a uniform punching of the steel plate of thickness, this structure is relatively good on overall leveling and dimensional accuracy, but its thickness is by the required maximum thickness design-calculated of intensity, therefore is unfavorable for the lightweight of vehicle body; Second kind of form is to be adopted the steel plate of different-thickness respectively by center pillar master brace panel leading portion and center pillar master brace panel back segment, make two parts, the fraction block structure that is formed by connecting by overlapping mode spot welding then, this structure makes moderate progress aspect body lightening, but the quantity and the processing capacity of part have been increased, especially influence the planarization of piece surface, also reduced the dimensional accuracy of part.
The utility model content
Technical problem to be solved in the utility model is, overcome the shortcoming of prior art, provide a kind of lightweight of automobile center pillar master brace panel structure to constitute, this formation promptly can satisfy the requirement of strength that the automobile side is hit test, can obviously alleviate the total quality of automobile center pillar master brace panel structure again, especially can guarantee the overall leveling of piece surface.
The purpose of this utility model is achieved by following technical proposals.
A kind of automobile center pillar master brace panel structure is made by the steel plate of different-thickness, and the utility model is linked to be a block plate with the steel plate of different-thickness, again punching out and whole fabricated part.The described block plate that is linked to be is to connect with welding manner; Described welding manner is with the butt joint form and uses the laser welding mode.Can guarantee that with the butt joint form integral planar is smooth, can guarantee that with the laser welding mode smooth welded seam, through welding are reliable, be connected firmly.
The steel plate of described different-thickness, its thickness is respectively: the thickness of slab is 1.5～2.1mm, gauge of sheet is 1.0～1.4mm.
As preferably, the steel plate of described different-thickness, its thickness preferably: the thickness of slab is 1.8mm, and gauge of sheet is 1.2mm.
Each section sheet thickness of the utility model center pillar master brace panel structure is that design-calculated has therefore reached part weight-saving purpose by intensity is required.
The automobile center pillar master brace panel texture ratio of the utility model and prior art has following beneficial effect:
Can guarantee part intensity, can satisfy the requirement of strength of the automobile side crash test of being undertaken by standard code;
Can guarantee the overall leveling of piece surface;
Reduce number of parts, reduce processing capacity;
Economical with materials, the quality that alleviates;
Cost-cutting.
Description of drawings
Fig. 1 is a kind of scheme drawing of automobile center pillar master brace panel structure;
Fig. 2 is the A-A section-drawing of Fig. 1;
Fig. 3 is the B-B section-drawing of Fig. 1;
Fig. 4 is the C-C section-drawing of Fig. 1.
D among Fig. 1 and Fig. 4 represents the laser welding weld seam.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of automobile center pillar master brace panel structure comprises hypomere and epimere, and hypomere is that thickness is the steel plate of 1.8mm, and epimere is that thickness is 1.2 steel plate, and the D place shown in the figure is that epimere and hypomere dock the junction with laser welding.Part is that disposable stamped forms, and the junction is butt joint form bonded assembly, so surfacing; Can guarantee that with the laser welding mode smooth welded seam, through welding are reliable, be connected firmly.
Middle-column main reinforced plate structure of the present utility model compared with the prior art, has following beneficial effect:
Can guarantee part intensity, can satisfy the requirement of strength of the automobile side crash test of being undertaken by standard code; Can guarantee the overall leveling of piece surface.
Reduce number of spare parts, reduce processing capacity; Economical with materials, alleviate quality 0.53kg; Reduce cost.
