Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a window panel mounting structure for mounting a window panel to a pillar, and more particularly to a window panel mounting structure having folded portions on both sides.

A flat front window glass has traditionally been installed as a front window panel at the front of an automobile's cabin.
In recent years, in order to improve the aerodynamic characteristics on both sides of the front window glass, as shown in Figure 1, the outside of the front pillar 1 has been It has been considered to use a front window glass W in which folded portions 2 extending all the way to the sides are bent on both sides.

The front window glass W has a resin film 5 between two bent glasses 3 and 4 as shown in FIG.
The bent portion 2, which is bent and formed so as to go around the outer surface of the front pillar 1, is colored with a colored resin film 6. To attach the front window glass W to the front pillar 1, apply adhesives 7 and 8 to the front and side surfaces of the front pillar 1, and attach the front window glass W to the front (second
(upper part in the figure) and apply adhesives 7 and 8 to the front window glass W and front pillar 1.
A possible structure is one in which the adhesive is hardened by inserting it between the two. In the figure, reference numeral 9 indicates a dam rubber that prevents the adhesive 7 from leaking, reference numeral 10 indicates a side window glass, and reference numeral 11 indicates a weather strip that makes the side window glass 10 watertight.

However, in the above-mentioned mounting structure of the front window glass W, due to variations in the width length l caused by manufacturing errors of the front window glass W, manufacturing errors of the vehicle body, and assembly errors of the front window glass W, , when the distance between the front window glass W and the outer surface of the front pillar 1 is different on the left and right sides, different deviations d and d' may occur between the surface of the front window glass W and the surface of the side window glass 10 on the left and right sides of the vehicle body. Yes, extreme care must be taken when assembling the front window glass W. Furthermore, if the front window glass W that has been assembled in one step is moved to eliminate the difference between the deviations d and d', there may be a problem in that the adhesion performance will deteriorate.

This invention was made in view of the above-mentioned problems, and it is possible to easily maintain a constant distance between the inner surface of the folded portion 2 of the window glass W and the outer surface of the pillar 1 when assembling the window glass W. The purpose is to provide a window panel mounting structure that is possible.

The purpose of this is to provide a window panel mounting structure in which bent portions are formed on both sides of the window panel, and the bent portions are rotated to the outside of the pillar to attach the window panel. This is achieved by a window panel mounting structure in which an engaging part is provided on the outer surface of the pillar corresponding to this convex part, and the convex part is locked to the engaging part with the original restoring force due to the panel elasticity of the window panel. .

Next, a front window panel mounting structure according to an embodiment of the present invention will be described in detail based on the drawings.

FIG. 3 shows a front window panel mounting structure according to a first embodiment of the present invention. In this embodiment, the front window glass W is
It is substantially the same as the front window glass W described above, and a resin film 5 is sandwiched between two folded glasses 3 and 4, and the folded portion 2 is colored with a colored resin film 6.

The bending angle of the bent portion 2 is smaller than the angle θ that the bent portion 2 makes with respect to the traveling direction when attached to the front pillar 13. That is, the bent portion 2 is bent inward from the bending angle in this state, and the length L of the window glass W in the vehicle width direction is smaller than that in the attached state. Further, at the rear of the inner surface of the bent portion 2, a convex portion 12 having a substantially right triangular cross section and extending in the vertical direction of the front window glass W is provided. This convex portion 12 is made of resin and has a side surface 12 that forms an oblique side in the cross-sectional shape.
It is adhesively fixed to the front window glass W so that a is directed toward the rear of the vehicle body (downward in FIG. 3), and the joint surface 12b forming the other side is directed toward the front.

On the other hand, the front pillar 13 is composed of a front pillar outer panel 13a and a front pillar inner panel 13b, and the outer side of the front pillar outer panel 13a is engaged with a portion corresponding to the convex portion 12 of the window glass W along the top and bottom. A protrusion 14 as a portion is provided. In this embodiment, the protruding strip 14 is formed by bending the front pillar outer panel 13a outwards into a chevron shape lower than the protrusion 12, and the slope of the front inclined surface 14a is gentle and the rear slope 14
b stands up substantially perpendicularly to the general surface of the front pillar outer panel 13a. The front window glass W is bonded with an adhesive 15 disposed between the front surface of the front pillar outer panel 13a and the front window glass W, and the convex portion 12 of the front window glass W and the convex strip 14 of the front pillar 13 are bonded together. It is attached to the front pillar 13 by engagement.

Note that reference numeral 16 in the figure is a dam rubber attached to the front window glass W, which prevents the adhesive 15 from leaking to the general surface of the front window glass W.

Therefore, in order to attach the front window glass W to the front pillar 13, the adhesive 15 is applied to a predetermined portion of the front pillar 13, and the front window glass W is inserted from the front. Then, the side surface 12a of the protrusion 12 and the inclined surface 14a of the protrusion 14
As they come into contact with each other and the front window glass W is pushed in, the folded portion 2 elastically expands outward. Then, after passing the top, the protrusion 12 moves inward with the original restoring force due to the elasticity of the front window glass W, and the joint surface 12b of the protrusion 12 and the inclined surface 14b of the protrusion 14 come into contact with each other, causing the protrusion to 12 is locked to the protrusion 14, and the front window glass W is attached to the front pillar 13. At this time, since the front window glass W is formed into a widthwise shape, the tip of the protrusion 12 contacts the outer surface of the front pillar outer 13a, and the height of the protrusion 12 contacts the inner surface of the front window glass W. The distance from the outer surface of the front pillar 13 is fixed. Further, the position of the front window glass W in the front and rear direction is also adjusted between the convex portion 12 and the engaging portion 1.
