Problems solved by technology

However, after the CAS surface is given in the shape, the lens position of the rearview mirror is then designed. The lens position is likely to be unable to match the CAS of the exterior rearview mirror given in the shape due to regulations and man-machine restrictions, which will affect the shape plan and style, resulting in engineering problems. Repeated matching and modification of the design and styling schemes lead to prolongation of the development progress of the vehicle

Embodiment Construction

[0036] The present invention will be described in more detail below with reference to schematic diagrams, wherein preferred embodiments of the present invention are shown, and it should be understood that those skilled in the art can modify the present invention described herein while still achieving the advantageous effects of the present invention. Therefore, the following description should be understood as the broad knowledge of those skilled in the art, but not as a limitation of the present invention.

[0037] like Figure 1-7 As shown, a method for quickly setting the position of an exterior rearview mirror includes the following steps:

[0038] Step S1: According to the R point (x 0 ,y 0 ,z 0 ), the unloaded ground line and the width of the vehicle, make the driver's left eye point E1 and right eye point E2, such as figure 1 shown. Specifically, the coordinates of the left eye point E1 relative to the R point are (0, -32.5, 635), and the coordinates of the right e...

Abstract

The invention provides a method for quickly setting the position of a lens of an outside rear-view mirror. The method comprises the following steps: firstly, making a left eye point E1 and a right eyepoint E2; then establishing two limiting surfaces and a left visual field area Z1; wherein the left visual field area Z1 comprises four boundary points; then selecting a point P1 (x1, y1, z1) on theleft front side of the R point (x0, y0, z0); establishing a spherical surface S by taking the P1 point as a sphere center; then establishing a visual field point area A1 formed by the left visual field area Z1 on the spherical surface S, importing the modeling model of the left outside rear-view mirror, adjusting the coordinate of the point P1 to enable A1 to cover the modeling model of the outside rear-view mirror, and finally cutting the spherical surface S by taking A1 as a boundary to obtain a design model S1 of the lens of the left outside rear-view mirror. The position of the outside rear-view mirror is rapidly set through parameterization design of the lens position of the outside rear-view mirror, and the efficiency of modeling and engineering development is improved.

Description

technical field [0001] The invention belongs to the technical field of automobiles, in particular to a method for quickly setting the position of an exterior rearview mirror lens. Background technique [0002] At present, most of the automobile design companies and manufacturers set the position of the exterior rearview mirror lens according to the CAS outline, regulations and human-machine requirements after the appearance of the CAS surface in the automobile design stage. However, after the CAS surface is given in the shape, the lens position of the rearview mirror is then designed. The lens position is likely to be unable to match the CAS of the exterior rearview mirror given in the shape due to regulations and man-machine restrictions, which will affect the shape plan and style, resulting in engineering problems. Repeated matching and modification of the styling scheme resulted in prolonging the development progress of the vehicle. Contents of the invention [0003] T...
