Abstract

The invention provides a rearview mirror knob track data modeling method, including obtaining the torque curve of the rearview mirror knob track; determining the structural parameters according to the design requirements of the torque or load, and constructing the structure parameters through the relationship between geometry and force The climbing torque formula and the downhill torque formula are obtained, and the torque curve is further divided into multiple climbing straight lines and / or downhill straight lines connected in sequence, so that the slopes of the climbing straight line and the downhill straight line can be converted by polar coordinates Finally, the corresponding relationship between the track radius and the angle increment is formed; the starting point and its corresponding return angle, correction angle and track radius are determined, and according to the preset angle increment, using the climbing and downhill torque formulas, sequentially Calculate the orbital radius of each climbing straight line and / or downhill straight line; fit the orbital radii obtained in sequence to draw the target orbital curve. The invention is implemented to solve the problem of low efficiency of rearview mirror knob track modeling in the prior art.

Description

technical field [0001] The invention relates to the technical field of the automobile industry, in particular to a rearview mirror knob track data modeling method. Background technique [0002] During the design process, each part of the car needs to be solidly modeled for strength analysis and structural optimization design. In addition, it can also be used for assembly analysis and CNC machining. [0003] In the prior art, the design of the rearview mirror knob track has the following disadvantages: (1) There is a problem with the distribution of the radius. Since the spring load changes throughout the process, the torque is not proportional to the slope of the radius change. The greater the difference in the spring load (2) The track surface curve is too simplified, it is only a spline fitting of edge points, and the torque change in the process cannot be guaranteed. This method is also difficult to control the transition area and the magnitude of the torque. Control the...
