Description
Technical field
The invention belongs to vehicle body field, refer to vehicle window guide rail field, specifically refer to the preparation method of the single-curvature face of cylinder formula guide rail of helix for a kind of automobile side window glass lifting.
Background technology
The form of the side window glass of car, due to the demand of moulding, adopts the hyperbolicity shape faces such as anchor ring or circle drum surface mostly at present.But hyperboloid, because of its essential feature, cannot be made the helix on the face of cylinder in single-curvature shape face and for side window glass, realize the lifting of glass.Therefore, when design side window glass guide rail, often to rely on the hyperbolicity glass surface that moulding provides according to moulding constraint, to simulate again the face of cylinder of a single-curvature again, thus required helix while trying to achieve side window glass lifting, i.e. side window glass guide rail.
As shown in Figure 1 to Figure 3, existing technology is the side window glass guide rail according to moulding, fromer rail 21 and rear rail 22 are projected in a plane, then adjust the position of plane, fromer rail projection 23 and rear rail projection 24 are coincided together as much as possible, then according to the track fitting overlapping, become a circle
Again by the normal direction of the plane face of cylinder that stretches, thereby in the face of cylinder 26, draw the helix 25 fitting with fromer rail and rear rail.The main points of making are, take fitting circle the end of as, and the normal of plane of take is the high face of cylinder.
The shortcoming of existing technology is:
1. after the projection of front and back guide rail, can not well overlap, tend to intersect, cause the face of cylinder of matching inaccurate.
2. the adjustment of plane does not have adjustment guiding that can reference, not only consuming time, and optimal case is difficult to obtain.
3. the fromer rail in moulding stage and rear rail, can not the actual jacking condition of actual response glass, and resulting scheme also will be revised repeatedly.For example two guide rails are not parallel, and its shape will be similar trapezoidal, be not up-narrow and down-wide be exactly wide at the top and narrow at the bottom, glass can, at loose place getaway, lose efficacy guide rail.

The shortcoming of this technical scheme is:
Only guaranteed that glass fits with guide rail on one side, glass another side cannot guarantee, glass groove excessive wear in lifting process that can cause another side glass to match, affect glass lifting motion, reduce glass speed, even glass is toppled over or clamping stagnation, shortens the glass lifter motor life-span, and increases the other problem of glass lifting system.
The third situation is: adjust glass in lifting process with the position of original hyperbolicity face, as shown in Figure 4, in this process, make glass fit with hyperbolicity face as far as possible as far as possible, then draw up the track of glass two borders in motion process, this track is glass guide-rail.The main points of this technical scheme are, 1, first have the movement position of glass, and hyperbolicity face guarantees to fit in glass motion process as far as possible; 2, according to motion fitting, go out the movement locus of Glazed fence.
The shortcoming of this technical scheme is:
Because the guiderail track simulating is not helix, can make lifting irregularity, cause Glazed fence and groove to cross quick-wearing.
