Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the present invention, and can not limitation of the present invention be interpreted as.
The glass surface on the driver door of design vehicle 200 is may be used for according to the vehicle 200 automobile door glass method of designing of the embodiment of the present invention.In description below the application, be described for the glass surface of vehicle 200 automobile door glass method of designing on the driver door of vehicle 200 such as automobile.Certainly, the present invention is not limited thereto, those skilled in the art understand, and this vehicle 200 automobile door glass method of designing can also glass surface on the tail gate of design vehicle 200.
As shown in Figure 3, according to the vehicle 200 automobile door glass method of designing of the embodiment of the present invention, comprise the following steps:
S1, suppose a moulding glass face 1, moulding glass face 1 is curved surface, and moulding glass face 1 has front border and rear border;
S2, according to the front border in moulding glass face 1 in step S1 and rear border respectively matching form the first circle 2 and the second circle 3;
S3, with the first axle 4 for S. A. makes the line in the center of circle of the center of circle that two faces of cylinder 21, first axle 4 is the first circle 2 in step S2 and the second circle 3;
S4, respectively by the front border in moulding glass face 1 with borderlinely wherein project to obtain two subpoints on two faces of cylinder 21 afterwards, be axis with the first axle 4 in step S3, cross two subpoints respectively and make two helix lines 22; And
S5, the first axle 4 crossed in step S3 make plane 5, plane 5 is crossing with the helix line of two in step S4 22 obtains two intersection points, plane 5 is done the camber line by two intersection points, take camber line as outline line, two helix lines 22 scan for clearance line and form bifilar helix glass surface.
Particularly, such as according to position and the window frame of mounting glass corresponding on front door of automobile, the moulding glass face 1 that hypothesis one is suitable with the border of window frame in advance, moulding glass face 1 has front border and rear border, front border is corresponding with the rear border (i.e. the side in contiguous moulding glass face 1) of the outside rear-view mirror trim board 201 of automobile, and rear border is corresponding with the front border (i.e. the side in contiguous moulding glass face 1) of B post trim board 202.Here, it should be noted that, the fore-and-aft direction in moulding glass face 1 is consistent with the fore-and-aft direction of automobile.
Extract the front border in above-mentioned moulding glass face 1 and rear border, because moulding glass face 1 is curved surface, thus two curves can be obtained, preferably, first circle 2 is by two end points of the front border in moulding glass face 1, the mid point matching of front border forms, second circle 3 is by two end points on the rear border in moulding glass face 1, the mid point matching on rear border forms, namely the first circle 2 can be formed by two end points of curve corresponding to front border and the mid point matching of curve, two end points of curve that second circle 3 is answered by back bound pair and the mid point matching of curve are formed, fitting effect is good, and choose conveniently, save design time.
Then the center of circle of the first circle 2 and the second circle 3 is found out respectively, and connect two centers of circle and make straight line (i.e. the first axle 4), with this straight line for S. A. does two faces of cylinder 21, here, the initial value of the radius on two faces of cylinder 21 is respectively the radius of the first circle 2 and the second circle 3, and namely the radius on two faces of cylinder 21 can first set with reference to the radius of the first circle 2 and the second circle 3.Wherein, the center of circle can be adjusted to coordinate to represent.
Then any point (namely wherein) in the front border (i.e. the rear border of outside rear-view mirror trim board 201) in moulding glass face 1 and rear border (i.e. the front border of B post trim board 202) is projected on two faces of cylinder 21 respectively, alternatively, front border be wherein one of them in two end points of front border, rear border be wherein one of them in two end points on rear border, preferably, two upper extreme points can be projected on two faces of cylinder 21 respectively and obtain two subpoints, with the line in the center of circle of the first round 2 and second circle 3 for axis, setting pitch, cross above-mentioned two subpoints respectively and make two helix lines 22, the length of helix line 22 can be arranged according to actual requirement, the pitch of two helix lines 22 now generated is equal, radius is not etc., here, the size of pitch can be arranged according to actual requirement, to meet styling design requirement.It should be noted that, " subpoint " here can be understood as that the shortest point of distance between selected point to its projection on the corresponding face of cylinder 21.
The line crossed between the first circle 2 and the center of circle of the second circle 3 does a plane 5, this plane 5 has an intersection point respectively with above-mentioned two helix lines 22, in above-mentioned plane 5, camber line is made by these two intersection points, the radius of camber line is formed by the intersection matching of moulding glass face 1 with plane 5, that is, the radius of circular arc can set with reference to the radius of moulding glass face 1 with above-mentioned plane 5 intersection, such as, can take up an official post with the intersection of plane 5 in moulding glass face 1 and get three points, cross these three points and simulate a circle, this radius of a circle is the radius of circular arc.Finally be outline line with this circular arc, scan for clearance line with above-mentioned two helix lines 22, just obtain the bifilar helix glass surface that engineering is feasible.
Now can the bifilar helix glass surface obtained repeatedly be revised, to make the border of the bifilar helix glass surface in step S4 consistent with the border in the moulding glass face 1 in step S1, compare traditional column type glass surface 100 ' and reduce restriction requirement to the moulding of automobile door glass periphery, compare traditional two circular ring type glass surfaces 100 " to achieve in lifting process theory state zero-deviation between moving glass phase face and two annulus glass surface.
Advantage during glass surface traditional according to the bifilar helix glass surface set that the vehicle 200 automobile door glass method of designing of the embodiment of the present invention obtains is each, and meet the requirement of moulding and engineering structure simultaneously.
According to the vehicle 200 automobile door glass method of designing of the embodiment of the present invention, under the requirement meeting car door engineering structure, reduce the restriction of glass surface to moulding.
