Description

Automobile door glass

Technical field

The utility model relates to the automobile field, particularly the automobile door glass field.

Background technology

In daily vehicle, the shape face of automobile door glass must satisfy the motion requirement of glass lifting, can not produce excessive application force in the process that glass moves under the constraint of guide rail and guide groove, otherwise will cause the glass lifting difficulty.The profile of past vehicle is generally comparatively single stiff, takes the regular face of cylinder as glass shape face more, thereby can easily satisfy the requirement of glass lifting.But in current vehicle design, pursuit is with Qu Weimei, curve, curved surface are widely adopted in the design of new model, and automobile door glass is as an important ring that influences car load profile style, inevitable requirement is consistent with vehicle body single-piece surface modeling, therefore, automobile door glass of the prior art mostly is bicurvature glass greatly.

The dipping and heaving of bicurvature glass is the synthetic of oscilaltion and lateral sliding, and glass is curve in lifting direction and sidesway direction, and glass path of motion is similar to an oblique circular arc.The compound motion of this complexity has proposed very high requirement to glass curve.Usually in the prior art, in vehicle body outside surface fairing process during the match glass curve, only guaranteeing that by constantly adjusting the glass curve fairing is distortionless, is that circular arc and the section line largest chord higher primary school that is parallel to vehicle body XY coordinate plane are in 10mm at sense of motion upper section line.Such approximating method and the glass curve that obtains thus can't be accomplished standardization, unitized, make troubles also for follow-up window regulator design, and design need carry out repeatedly correction of motion after finishing, and do not get rid of and can occur revising the possibility of doing over again in the subsequent design on a large scale.

Therefore, the design of existing automobile door glass can not be accomplished unified and standard, can't guarantee the smooth realization of glass lifting motion, influences other designs of car door assembly simultaneously, and design efficiency is low.

The purpose of this utility model is to have overcome above-mentioned shortcoming of the prior art, and a kind of design cycle standard, production efficiency height, automobile door glass that design process is complete are provided.

In order to realize above-mentioned purpose, automobile door glass of the present utility model has following formation:

This automobile door glass, its principal feature are that the face of described automobile door glass is the part curved surface on the anchor ring.

(1) it is enough big to lead radius of circle R;

(2) bus radius of circle r is much smaller than leading radius of circle R.

In the bus radius of circle r of the anchor ring of this automobile door glass condition satisfied with leading radius of circle R, bus radius of circle r is less than leading 1/10 of radius of circle R.

The theoretical boundary, front and back of this automobile door glass and the helix line on the described anchor ring coincide, and the scope of the helical angle of this helix line is positive and negative 30 degree.

The specific embodiment

In order more to be expressly understood technology contents of the present utility model, describe in detail especially exemplified by following examples.

See also shown in Figure 1ly, for seeking a kind of standardization approximating method of bicurvature glass curve, we adopt the deformation surface of cylinder---anchor ring, are bent into an annulus as the face of cylinder with rule with certain radius R.Like this at R enough big and cylindrical radius r ((glass curve that intercepts from anchor ring during R still is approximately cylinder.The motion of glass can be thought a kind of screw motion, and its path of motion is the part of anchor ring helix line.

See also shown in Figure 2ly again, the math modeling of anchor ring glass is as follows:

1, anchor ring

Radius is that the circle of r is an anchor ring along the normal direction of circle with the radius R curved surface that obtains that rotates, and circle r is a bus, and circle R is for leading moving-wire.The geometric parameter equation of anchor ring is:

x＝(R+rcosθ)cosα，

y＝(R+rcosθ)sinα，

Z=rsin θ, 0≤α≤2 π wherein, 0≤θ≤2 π

Anchor ring need to determine four elements, comprise two form elements and two position key elements:

(1). bus radius of a circle r;

(2). lead radius of a circle R;

(3). lead the central coordinate of circle of circle;

(4). lead the normal vector of circle.

Wherein key element (1), (2) are the base quantity of anchor ring, have determined the basic configuration of anchor ring; And key element (3), (4) can be determined the coordinate position of anchor ring.

2, annulus helix line

Being located at has 1 A when the center of circle O1 of circle K does the constant angular velocity rotation on the round K, circle K does the constant angular velocity rotation around the axle OZ with its coplane, and the track of then putting A is the annulus helix line.

The annulus helix line is as the curve on the anchor ring, except that four fundamentals that need anchor ring, also the another one key element should be arranged, the helical pitch S of helix line (S is an arc length), promptly put the A arc length that circle K turns over around OZ when the center of circle O1 of circle K rotates a circle, S=π R α/180.The helical pitch of helix line is counted n or helixangle (being defined as any point place tangent line and the angle of cut of leading the last corresponding point position normal of circle on the helix line) on the also available whole anchor ring of helical pitch S.The annulus helix line θ=n α that satisfies condition as shown in Figure 2, promptly the equation of annulus helix line is:

x＝[R+rcos(nα)]cosα，

y＝[R+rcos(nα)]sinα，

Z=rsin (n α), wherein 0≤α≤2 π

The condition of using on engineering is as follows:

In theory, the glass face is the local curved surface on the anchor ring, and the path of motion of glass is that helical angle is a section of annulus helix line of β.Because section circumference difference at p place, different poles footpath on the anchor ring, can not overlap fully on anchor ring as the glass on the go of local curved surface on the anchor ring, certain skew can appear.As long as but satisfy condition:

(1) R is enough big;

(2) r＜＜R (common r＜R/10);

(3) path of motion is in the outside of anchor ring all the time.

Then offset delta is minimum in the lifting process, can be similar to think and overlap with anchor ring.Simultaneously under the situation that above-mentioned condition is set up; we can be reduced to a ring cross-section line that is projected as straight line on vehicle body coordinate plane XOZ with the theory locus toroidal helical line segment of glass motion in the practical engineering application, and parallel and this section line can be made the front and rear side boundary line of glass.Can make things convenient for the design of window regulator guide rail, guide groove in the subsequent design so greatly.

Scheme in actual engineering is as follows:

Above-mentioned principle can be applied to the vehicle body outside surface fairing, carry out the design of bicurvature automobile door glass, window regulator fast.

When in body drawing, the clay model points cloud being carried out surface smoothing,, these cross hatchs are fitted to circle and analyze two base quantity r and the R that its change in radius can be determined anchor ring substantially at many grid section dotted lines of vehicle window point cloud place intercepting.Anchor ring of mode match by constantly approaching makes it near vehicle body outside surface point cloud.Determine glass shape according to window frame structure, projection line and the Z axle angled β of the border, front and back of glass on coordinate plane XOZ.β is the helical angle of the theory movement track annulus helix line of glass.As the scheme that the utility model can be implemented, the scope of this helical angle spends-30 usually+30 degree between, the helix line that promptly has the interior helical angle of this scope on the theoretical boundary, front and back of automobile door glass and the garden anchor ring coincides.As preferred embodiment of the present utility model, the best angle of the helical angle of this helix line is 14 degree, 15 degree, 16 degree.After determining the position of guide rail, just can on anchor ring, cut the clearance line that guide rail, guide groove, thereby design guide rail and guide groove fast, finish the design arrangement of whole window regulator then.

In this specification sheets, the utility model is described with reference to its certain embodiments.But, still can make various modifications and conversion obviously and not deviate from spirit and scope of the present utility model.Therefore, specification sheets and accompanying drawing are regarded in an illustrative, rather than a restrictive.
