Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a water drainage structure for a front window mounting portion of an automobile, and more particularly to a water drainage structure for a front window panel mounting portion of an adhesive type for adhesively fixing a front window panel to the edge of an opening in a vehicle body.

Figure 1 shows the structure around the front window of a car. A glass front wind panel 1 (hereinafter referred to as the window glass) is fixed to the edge of the opening of the car body with adhesive, and the peripheral edge of the window glass 1 is I am trying to hide and decorate it with Wind Mall 2. (Automotive Engineering Complete Book Vol. 13 "Car Body" P162 Sankaido) By the way, when the window glass 1 is glued to the edge of the car body opening in this way, the window glass 1 will slide down due to its own weight, so it is usually A plurality of spacers (not shown) made of elastic material are arranged on the lower shelf of the edge, and the window glass 1 is positioned using these spacers, but this not only increases the number of parts but also increases the number of parts. However, the number of man-hours required increases.

Therefore, as an alternative to the conventional use of spacers, the present applicant has developed a window glass mounting structure in which the window molding 2A on the lower side of the window glass 1 itself has a spacer function and the window glass 1 is properly adhesively fixed. developed.

As shown in FIG. 2, this window molding 2A has a stepped portion 3 at the upper center thereof, and this stepped portion 3 holds the lower edge of the window glass 1.
A groove 4 and a projection 5 are provided on the rear side following the step 3, and the adhesive 7 is inserted between the groove 4 and the projection 5 and the flange 13 to increase the bonding area as much as possible. Thus, it is possible to securely bond and fix the window glass 1 together with the window glass 1.

Further, a plurality of lips 6 are formed at the bottom of the window molding 2A, and the space between the window molding 2A and the shelf 12 is sealed in multiple stages by these lips.

However, even if the space between the lip 6 and the shelf 12 is sealed in multiple stages with the lip 6, if these seals are incomplete, water may leak into the close contact area between the lip 6 and the shelf 12 during rain. There was a concern that the water could penetrate and accumulate in the gaps between the lips, causing corrosion.

Therefore, due to the shape of the vehicle body, we considered opening drain holes 14 as shown by broken lines in FIG. 2 on both sides of the shelf 12 at the lowest position, and draining water through the drain holes 14. However, in such a means, the shelf portion 12 and the flange portion 13 are not connected to the cowl top 1 constituting the cowl box 10 in front of the window glass 1.
1, the water drain hole 14 opens into the cowl box 10. This cowl box 10 is a frame member in the vehicle width direction of the front part of the vehicle body, and also functions as an outside air introduction section that takes in outside air from a grille 15 formed on the cowl top 11 and sends it to an air conditioning unit (not shown). However, if the drain hole 14 is simply opened as described above, the drain hole 1
4, there is a risk that water may flow backwards due to the wind pressure in the cowl box 10. Therefore, it is necessary to install piping in the drain hole 14, which is commonly used in this type of window, to avoid the influence of wind pressure. We had no choice but to take the measure of leading the water out of the cowl box 10, but we encountered a new problem in that this would complicate the structure.

In view of this situation, the present invention provides the following steps when draining water in the above-mentioned wind panel mounting structure:
The object of the present invention is to provide a water drainage structure that has a simple structure and can quickly and reliably drain water to the outside of the vehicle.

In order to achieve the above object, in the present invention, a lower shelf part of the opening edge of the vehicle body is extended straight in the vehicle width direction together with a flange part connected to the shelf part, and is joined to the front surface of the front pillar. By forming a drainage gutter opening in the front part of the front pillar, and installing a nozzle below the drainage gutter to blow out the outside air introduced into the cowl box from the lower side of the opening, the cowl can be easily cleaned during driving. By effectively utilizing the wind pressure inside the box, the water discharged into the drainage gutter section by the ejector effect is actively drained at the opening of the drainage gutter section.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

In FIG. 3, a dam member 8 made of an elastic material such as rubber or resin is preliminarily attached around the inner surface of the window glass 1 whose peripheral edge is fixed to the edge of the vehicle body opening with an adhesive 7. It is fixed with adhesive so that the adhesive 7 does not protrude inside. As shown in FIG. 2, a wind molding 2A that also serves as a spacer made of an elastic material such as rubber or resin is interposed between the lower edge of the window glass 1 and the lower shelf 12 of the vehicle body opening edge. The window molding 2A is fixed together with the window glass 1 to the flange portion 13 with an adhesive 7. and,
This shelf part 12 and a flange part 13 connected to the shelf part 12 extend straight in the vehicle width direction and are joined to the front surface of the front pillar 17, and have a V-shaped cross section opening in the front part of the front pillar 17. A drainage gutter portion 16 having a shape is formed. Further, along the lower side of this drainage gutter section 16, one side wall of the gutter section 16, that is, an extension wall of the shelf section 12, is communicated with the inside of the cowl box 10, and the drain section 16 is connected to the lower side of the opening of the gutter section 16. Nozzle 18 to open
has been formed. Here, since the drainage gutter part 16 is to be joined to the front surface of the front pillar 17 as described above, in order to match the adhesion surface of the window glass 1, one side joining flange part 1 of the front pillar 17
Remove the 7a setting from one side of the window glass,
It is set outside the front part of the front pillar 17, and the side part of the window glass 1 is fixed to the front surface of the front pillar 17 with an adhesive 7. Further, the side window molding 2B extends from the side edge of the window glass 1 to the front joint flange 1 of the front pillar 17 as shown in the figure.
7a, and its lower side extends to a position hidden under the front fender 19, covering the end of the lower window molding 2A, the drain gutter 16, and each end of the nozzle 18.

According to the structure of the above embodiment, it penetrates into the close contact area between the lower window molding 2A and the lower shelf part 12,
Water that enters the gap between the lips 6 at the lower bottom of the wind molding 2A is concentrated on the front pillar 17 side due to the slope of the shelf 12 in the vehicle width direction. Then, this water is guided to a straight drainage gutter section 16 formed by an extension of the shelf section 12 and the flange section 13.
Water is drained to the front side of the front pillar 17 from the end opening 6. Here, especially when the car is running, the internal pressure inside the cowl box 10 increases due to the wind pressure, and as a result, the outside air introduced into the cowl box 10 flows through the nozzle 1 installed along the lower side of the drainage gutter section 16.
8, the air blows out vigorously from the lower side of the opening of the gutter section 16,
The water discharged to the drain gutter 16 by this blown air is actively drained from the gutter opening due to the ejector effect. Therefore, water that tends to accumulate in the gap between the lips 6 due to poor air circulation can be forcibly sucked into the gutter 16 and drained by this ejector effect, thereby eliminating the accumulation of water. Corrosion caused by accumulation can be prevented.

As described above, according to the present invention, water that permeates through the close contact between the wind molding that also serves as a spacer on the lower side of the front window and the shelf to which the wind molding is attached is prevented due to the shape of the shelf in the vehicle width direction. Due to the head difference, the water flows towards the front pillar between the shelf and the flange connected to it, and is guided to the straight drainage gutter formed by the extension of the shelf and the flange. In particular, when the car is running, a part of the outside air introduced into the cowl box is blown out from a nozzle attached to the bottom of this drainage gutter, creating an ejector effect. Therefore, water can be positively drained from the gutter, and corrosion from the lower side of the opening edge of the vehicle body can be avoided. Furthermore, since there is no need for complicated piping for drainage, there is no adverse effect on the number of man-hours required for assembling the vehicle body, which has many practical effects.
