Confirmation method of working curved surface of window lifter guide rail of vehicle door

Abstract

The invention discloses a confirmation method of the working curved surface of a window lifter guide rail of a vehicle door. The method is characterized by comprising the following steps of: confirming the motion curved surface of the vehicle window glass on the basis of the shapes of a whole vehicle door, a guide groove and the vehicle window glass; establishing a motion analysis mechanism of the vehicle window glass through the motion analysis and simulation of a DMU (Dynamic Measuring Unit) module of CATIA (Computer-Aided Three-Dimensional Interactive Application) software to simulate the motion of the vehicle window glass; and scanning the working curved surface of the window lifter guide rail under the conditions of ensuring the minimum friction between a slider and the guide rail and the minimum deformation of the slider. The motion curved surface of the vehicle window glass is confirmed by the following steps of: moving the vehicle window glass from the upper end of the guide groove to the lower end of the guide groove; evenly sampling points on the guide groove; recording the position of the glass curved surface of the position; and then, fitting the motion surface of the vehicle window glass with the curved surfaces. By adopting the CATIA software, the invention accurately solves the confirmation problem of the window lifter guide rail of the vehicle door with high efficiency.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a method for determining a working curved surface of a guide rail of a door and window machine. Background technique [0002] In the car door and window shaker system, the guide rail surface that determines the movement trajectory of the window glass is the load running surface for the glass to move up and down. The guide rail and its curved surface have an important influence on the running stability of the entire window shaker system and the life of the window shaker. Since the door belongs to the body system, the body is given, so the body determines the door, and the shape of the door determines the shape of the guide groove. Due to the influence of wind resistance, there is a requirement for the glass surface, so the glass surface also belongs to the control of the body. Part, so the determination of the shape of the guide rail of the window shaker is based ...
