DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window glass mounting structure for an automobile, which can reduce the number of parts and improve the appearance.

[0002]

2. Description of the Related Art FIG. 2 shows an automobile having a back door 50. An opening hole 52 for a window is formed in a door panel 51 constituting the back door 50.
A window glass 53 is attached to the window opening 52 via an adhesive (not shown).

FIG. 3 shows a conventional window glass 53 mounting structure. The door panel 51 is composed of a door outer panel 54 and a door inner panel 55. At the periphery of the window opening 52, the door panels 51 are brought close to each other and overlap each other, and their front flange portions 54a and 55a are joined. An opening trim 56 is attached to the flange portions 54a and 55a, and forms a peripheral portion of the window opening 52. The window glass 53 is bonded to the flange portion 54a of the door outer panel 54 by applying an adhesive 57. On both sides of the adhesive 57, the dam rubber 5
8, 59 are provided, and a molding 60 is attached around the window glass 53 to prevent the adhesive 57 from protruding.

FIG. 4 shows a door panel 5.
1 and a flange portion 54b of the door outer panel 54
The length H _2, the length H of the flange portion 54a shown in FIG. 3
Longer than ₁ (H ₂ > H ₁ )
7 is formed so as to correspond to the protrusion due to the displacement of 7 (the position indicated by the dotted line).

[0005]

According to the above prior art, the technique shown in FIG. 3 uses the dam rubbers 58, 59 and the molding 60 to increase the cost, and the technique shown in FIG. 4 requires the flange of the door outer panel 52. Part 5
The longer 4b of the length H _2, since the large adhesion surface, there is a problem that the rear visibility deteriorates.

An object of the present invention is to solve the above-mentioned problems, to provide a mounting structure for a window glass for an automobile, in which cost can be reduced by eliminating a dam rubber and a molding, and a rear view can be secured by reducing the width of an adhesive surface. Aim.

[0007]

According to the present invention, in order to solve the above-mentioned problems, an adhesive is applied to a peripheral portion of a window opening, and the window glass is attached to a vehicle body with the adhesive. In the structure, a groove is formed along the periphery of the entire periphery or a part of the periphery of the window opening hole on the outer peripheral side of the adhesive application surface of the periphery of the window opening, and the outer periphery of the groove is formed. And a step is provided inside the periphery of the window glass.

[0008]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a cross-sectional view of the same portion as the cross-sectional view taken along the line AA of FIG. In FIG. 1, reference numeral 1 denotes a door panel mounted as a back door of an automobile,
Reference numeral 2 denotes a window glass mounted on the window opening 3 of the door panel 1.

The door panel 1 is composed of a door outer panel 4 and a door inner panel 5. At the peripheral edge 6 of the window opening hole 3, the door panel 1 is brought close to each other and overlapped, and its front flange portions 4a, 5a are joined. ing.

The peripheral portion 6 of the window opening 3, that is,
An adhesive application surface 8 for applying an adhesive 7 for bonding the window glass 2 is formed on the flange portion 4 a of the door outer panel 4, and an outer peripheral side of the adhesive application surface 8 is provided around the periphery of the window opening hole 3. A groove 9 is formed on the entire area or a part of the portion 6 along the periphery. A step 10 is provided on the outer peripheral side of the concave groove 9 so as to be located inside the peripheral edge of the window glass 2.

The step portion 10 has a predetermined width h higher than the flange portion 4a of the door outer panel 4 to reduce the distance L between the window glass 2 and the outer corner portion 4b of the door outer panel 4 and the window glass 2. And the concave groove 9 is invisible from the gap 11 between them. Flange portion 4a length H ₃ to the tip end door outer panel 4 from the stepped portion 10 of the door outer panel 4 is shown in FIG. 4, it is shorter than the length H ₂ of the conventional flange portion 54b of the door outer panel 52 It is set as follows.

According to the above construction, the adhesive 7 is applied to the adhesive application surface 8 provided on the flange 4a of the door outer panel 4.
Is applied, and the window glass 2 is bonded. At this time,
When the adhesive 7 protrudes from the adhesive application surface 8, it enters the concave groove 9, so that it does not protrude into the window opening hole 3. Since the adhesive 7 that has entered the concave groove 9 is blocked by the step portion 10, it cannot be seen from the gap 11 between the outer corner 4 b of the door outer panel 4 and the window glass 2. Also, a groove 9 is formed in the peripheral edge 6 of the window opening 3.
Is formed, the rigidity of the door outer panel 4 can be improved.

[0013]

As described above, according to the structure for mounting a window glass for an automobile according to the present invention, an adhesive is applied to the periphery of the window opening, and the window glass is bonded to the vehicle body with the adhesive. In the mounting structure of the automotive window glass, on the outer peripheral side of the adhesive applied surface of the peripheral portion of the window opening hole, the entire or a part of the window opening hole peripheral portion, forming a concave groove along the periphery, Since a step is provided on the outer peripheral side of this groove and inside the periphery of the window glass, when the adhesive protrudes from the adhesive application surface, it enters the groove and protrudes into the window opening hole. Never come.
Furthermore, since the adhesive that has entered the concave groove is blocked by the step, it cannot be seen from the gap between the outer corner of the door outer panel and the window glass. Therefore,
The cost can be reduced by eliminating the dam rubber and the molding, and the rear view can be secured by reducing the width of the bonding surface. Further, since the concave groove is formed in the peripheral portion of the window opening hole, the rigidity of the door outer panel can be improved.
