Design method of vehicle door glass

Abstract

The invention discloses a design method of vehicle door glass. The method comprises the following steps: S1, supposing a molding glass surface, wherein the molding glass surface is a curved surface and is provided with front and rear boundaries; S2, fitting to form first and second circles according to the front and rear boundaries of the molding glass surface respectively; S3, forming two cylindrical surfaces by taking a first axis as a rotation axis, wherein the first axis is a connecting line of the circle centers of the first circle and the second circle; S4, projecting one point on the front and rear boundaries of the molding glass surface to the two cylindrical surfaces to obtain two projection points respectively, and forming two spiral lines with the first axis as the axis by passing through the two projection points respectively; S5, forming a plane by passing through the first axis, wherein the plane is crossed with the two spiral lines to obtain two cross points, forming an arc passing through the two cross points on the plane, and sweeping with the arc as a contour line and the two spiral lines as guide lines to form a double spiral line glass surface. According to the design method of the vehicle door glass provided by the embodiment of the invention, the limitation of the glass surface to modeling is reduced when the requirement on a vehicle door engineering structure is met.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a method for designing vehicle door glass. Background technique [0002] It is pointed out in related technologies that with the development of diversified styling styles and streamlined trends, it is difficult for traditional car door glass surfaces to meet the design requirements of styling and door engineering structures at the same time, because it often requires a compromise between styling and engineering structures, which limits the flexibility of styling. play. In the past, the common mathematical models of glass surfaces were cylinder type and double ring type. These two types of glass surface models have their own limitations. [0003] Such as figure 1 As shown, the advantage of the cylindrical glass surface is that the front and rear guide rails of the glass are two helical lines on the cylindrical model, so that there is no deviation between the moving glass surface and the ...
