Headlight switching knob track data modeling method

Abstract

The invention provides a headlight switching knob track data modeling method. The headlight switching knob track data modeling method comprises the steps that a torque curve of a headlight switching knob track is obtained; structural parameters are determined according to the design requirements of torque or load, a climbing torque formula or a downhill torque formula are established according to the structural parameters and the geometry and stress relation, the torque curve is divided into multiple sequentially connected climbing straight lines and / or downhill straight lines so that the slopes of the climbing straight lines and the downhill straight lines can be converted into the corresponding relation that height changes with angle increment through column coordinates; a starting point and the return angle, correction angle and height corresponding to the starting point are determined, the heights of the climbing straight lines and / or the downhill straight lines are calculated in sequence by utilizing the climbing torque formula and the downhill torque formula according to preset angle increment; the sequentially calculated heights are fit, a three-dimensional target track curve is drawn, and the curve is drawn. By implementing the headlight switching knob track data modeling method, the problem of low headlight switching knob track data modeling efficiency in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of machinery industry, in particular to a method for modeling track data of a headlight switch knob. Background technique [0002] During the design process, mechanical parts need to be solidly modeled for strength analysis and structural optimization design. In addition, they can also be used for assembly analysis and CNC machining. [0003] In the prior art, the design of the headlight switch knob track has the following disadvantages: (1) The design of the track surface is too simplified, and the spring design process is only related to two points of load, resulting in only two points of the entire track being close to the target value, which cannot be guaranteed The torque changes during the process, and the torque growth slope cannot be controlled to ensure the return; (2) There is a problem with the height distribution. The premise of determining the ratio according to the area is that the height growt...
