The outer panel flange 4 is formed such that the indoor end of the outer panel 1 is parallel to the outer side surface 2 of the vehicle body, and the window glass 5 is slidably supported inside the outer panel flange 4, and a drain hole 6 is formed therein. An inner adhesive part 10 formed by bonding an outer panel flange 4 to the outer panel flange 4 with an adhesive member 9 to an outer sash frame 7 that fits into the window opening 3, and an inner flange 8 extending toward the indoor side of the outer frame 7. It's getting more familiar.

Note that a space S is opened between the outer panel 1 of the window opening 3 and the sash outer frame 7 over the entire circumference of the sash outer frame 7, and a space 18 is formed between the outer panel 1 and the sash outer frame 7. was formed.

Therefore, according to this conventional window frame mounting structure, when the window frame is mounted, the sash outer frame 7 is pressed from the outside of the vehicle body to the window opening 3 of the outer panel 1 through the adhesive member 9 at the inner adhesive part 10. It is attached.

Further, rainwater, condensed water, etc. (hereinafter referred to as condensed water) accumulated inside the sash outer frame 7 falls from the drain hole 6 to the outer panel 1, and is discharged from the space S to the outside of the vehicle.

(Problems to be Solved by the Invention) However, in the conventional car body window frame mounting structure, the sash outer frame 7 and the outer panel 1
is cantilevered and the support rigidity is weak.
In addition, outside rainwater, car wash water, etc. may enter the space 18 from the space S, and the water in the space 18 may enter the room through the drain hole 6. There were problems in that water could be blown up from the drain hole 6 due to the difference in air pressure between indoors and outdoors, and there was also a problem in that the window glass could not slide smoothly due to the infiltration of dust. .

(Means for solving the problem) Therefore, the present invention was devised for the purpose of solving the above-mentioned problems.In order to achieve this purpose, the present invention has a method of removing the outer panel from the outside of the vehicle body into the interior. a panel extension portion bent inward and extending around the periphery of the window opening; an outer panel flange formed so that the indoor end of the outer panel is parallel to the outer side surface of the vehicle body; The fitted sash outer frame, an inner flange extending to the indoor side of the sash outer frame, an inner adhesive portion formed by bonding the inner flange and the outer panel flange with an adhesive member, and an outer sash outer frame. A space formed between the lower part of the frame and the panel extension,
In the window frame mounting structure for a vehicle body, the outer surface of the vehicle body near the bent portion of the outer panel is an outer panel adhesive portion, an outer flange is extended from the sash outer frame toward the outer panel adhesive portion, and the outer panel A flange and the outer panel side adhesive part are bonded with an adhesive member to form an outer adhesive part, a drain hole is formed in the lower part of the sash outer frame toward the space, and a drain hole is formed in the outer adhesive part of the lower part of the sash outer frame toward the space. A water drain part is formed which communicates the space with the outside of the vehicle, and the water drain hole and the water drain part are arranged to be shifted in the extending direction of the lower part of the sash outer frame.

(Function) Therefore, when attaching the window frame (outer sash frame) to the vehicle body (outer panel), attach adhesive material to the inner and outer flanges of the sash outer frame in advance, or attach the adhesive to the outer panel flange of the outer panel. Attach the adhesive material to the adhesive part on the outer panel side in advance, and press the outer frame of the sash to the window opening of the outer panel from the outside of the car body. Attach the window frame to the car body by gluing the adhesive parts at the same time.

In a window frame installed in this way, water due to condensation, etc. that accumulates at the bottom of the sash outer frame is discharged from the drain hole into the space, and then transmitted through the panel extension facing this space. The water is discharged from a drainage part formed in the outer adhesive part between the outer flange and the outer panel side adhesive part.

In addition, if dust or water tries to enter the inside of the window frame from the outside, it will enter through the opposite route to the above drainage route, but it will enter through the water drainage part provided on the outside adhesive part. With the drain hole provided in the window frame,
Since they are arranged offset in the extending direction of the lower part of the sash outer frame, water, dust, etc. that have entered the space from the drain part are difficult to enter into the drain hole side.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.
In describing this embodiment, we will take as an example a window frame mounting structure for a car body that uses a sash outer frame that has a sliding window glass on the inside that can be slid on a rail. I will explain it with the following.

Reference numeral 9 denotes an adhesive member that adheres the inner flange 8 and the outer panel flange 4 to form an inner adhesive portion 10.

Reference numeral 13 denotes an outer panel adhesive part, which is used when the outer panel 1 forms the window opening 3.
A step m is formed parallel to the outer side surface 2 of the vehicle body at a portion where the outer panel 1 is bent from the outer side surface 2 of the vehicle body toward the indoor side.

Reference numeral 14 denotes an outer flange, which extends from the sash outer frame 7 toward the outer panel adhesive portion 13.

15 is an adhesive member, which is attached to the outer flange 1
4 and the outer panel side adhesive part 13 are adhered to form an outer adhesive part 16.

Further, the adhesive members 9 and 15 are made of an adhesive material that hardens after adhesion and becomes elastic, and a portion of the adhesive member 15 disposed below the sash outer frame 7 is provided with the adhesive material shown in FIG. As shown, a notch is provided in the drain hole 6 and the sash outer frame 7 so as to be offset in the extending direction, and the notch is used as a water drain portion 17.

Incidentally, the outer side surface 2 of the outer panel 1 and the outer side surface of the outer flange 14 are substantially on the same plane.

Further, the water drain hole 6, the space 18, and the water drain part 17 form a path for drainage from the inside of the sash outer frame 7 to the outside of the vehicle.

Next, the operation of the embodiment will be explained.

When attaching the window frame to the vehicle body, the adhesive member 9 is attached to the inner flange 8 of the sash outer frame 7 and the adhesive member 15 is attached to the outer flange 14 in advance, and the outer sash is attached to the window opening 3 of the outer panel 1.

Now, the inner flange 8 and the outer panel flange 4 are bonded together, and the outer flange 14 and the outer panel side bonding portion 13 are bonded together at the outer bonding portion 16 to bond and attach the window frame to the vehicle body.

In situations where there is strong wind and rain outside the vehicle, dust is flying, or the vehicle is being driven at high speed in the rain, the outer adhesive portion 1 may be
6, and because the positions of the drain part 17 and the drain hole 6 are shifted, rainwater, dust, etc. from the outside enter the interior of the vehicle, and first the outside of the vehicle and the space 18 are separated from each other. Since it is further blocked between the space 18 and the room, there is almost no intrusion of such rainwater or dust.

In addition, condensed water, etc. accumulated inside the sash outer frame 7 passes through the drain hole 6 and falls into the space 18, then flows along the outer panel on the lower surface of the space 18, and is discharged from the water drain 17 to the outside of the vehicle. .

Although the embodiments of the present invention have been described above in detail with reference to the drawings, the specific configuration is not limited to these embodiments, and the present invention may be modified without departing from the gist of the present invention. included.

For example, in this embodiment, an adhesive that hardens after adhesion and becomes elastic is used as the adhesive member, but it may also be one in which the adhesive is applied to the outer surface of a tape-shaped elastic body.

Regarding the water drain portion 17 as well, in this embodiment, the adhesive member 15 is cut out in some places, but as shown in FIG. It's okay.

In this example, a vehicle body window frame mounting structure using a sash outer frame having a sliding window glass on the inside that can be slid on a rail is taken as an example. A sash outer frame that is available may be used, or one side of the window glass may be fixed and the other side may be left open.

(Effects of the invention) As described above, in the car body window frame mounting structure of the invention, an outer adhesive part is provided in addition to the conventional inner adhesive part, and the outer panel and the sash outer frame are connected at two locations in total. By adhering the sash, the supporting rigidity of the outer frame of the sash is increased, and the installation work to the vehicle body is much easier than fixing with screws. Another advantage is that the windows can be used on the car body.

Furthermore, since the space between the sash outer frame and the outer panel is closed by the outer flange of the sash, the lateral gap S in the prior art does not exist.
In addition to improving the appearance, it has the effect of reducing air resistance and wind noise. Moreover, at this time, the problem of draining water inside the sash, which becomes difficult, is covered by the adhesive material on the outer adhesive part except for the water draining part, and the water draining part and the water draining hole are arranged in the extending direction of the lower part of the outer frame of the sash. By staggered placement, the exterior appearance is not degraded, water drains smoothly from the window frame, and rainwater, car wash water, dust, etc. from outside the vehicle can be prevented from entering the interior. In addition, since a sealing member is not provided independently, the number of parts and manufacturing cost can be reduced.

In addition to the above-mentioned effects, in the embodiment,
After the outer panel and the sash outer frame are bonded together, the outer surface of the outer panel and the outer flange of the sash outer frame are made to be approximately on the same plane.
The air resistance of the vehicle body during driving can be reduced, and wind noise can also be reduced.Furthermore, the appearance has the effect of reducing the appearance of protrusions, which is aesthetically pleasing.
