Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a molding mounting structure for a back door of an automobile.

[Prior art]

A conventional molding mounting structure for a back door of an automobile will be explained based on FIGS. 1 and 2.

In the figure, D is a door having a window glass installation opening in the center;
1 shows a back door of an automobile whose side frame portion is formed by a side frame 1 having a closed cross section.

The side frame 1 is, for example, roll-formed from a single plate, and has a substantially square-shaped closed cross-section.

This side frame 1 has a window glass 2
The window glass 2 is disposed along the side edge of the window glass 2 with one side facing the inner surface 2a of the window glass 2, and the window glass 2 is bonded to the one side with a structural adhesive 3.

A welding flange 40 of the side frame 1 is formed at a position substantially flush with the adhesive surface 1a of the window glass 2 and close to the end surface 2b of the side edge of the window glass 2.

The window molding 60, as shown in FIG.
It is attached along the end surface 2b of the side edge of the window glass 2 via a retainer R fixed to this welding flange 40 with fasteners such as bolts B and nuts N.

In such a mounting structure of the window molding 60, the nut N of the fastener protrudes from the back side of the side frame 1, which is unsightly.In particular, when the back door D of an automobile is opened, the back side of the back door D is visible to the human eye. Since the rear surface of the side frame 1 is easily visible to the human eye, it was necessary to improve its appearance.

[Purpose of invention]

The present invention has been made in view of the above-mentioned conventional drawbacks, and an object of the present invention is to provide a back door for an automobile that can improve the appearance of the back side of the back door.

[Structure of the invention] In order to achieve such an object, the present invention provides a back door for an automobile as described above, in which the frame is arranged along the side edge of the window glass, and one side thereof is attached to the inner surface of the window glass. The frames are arranged to face each other, one side of which serves as an adhesive surface for bonding the window glass, and a welding flange formed close to the adhesive surface of the frame is attached to the end surface of the side edge of the window glass. A molding locking portion is formed by standing upright along the window, and a window molding that covers the side edge of the window glass is fitted into this molding locking portion to lock the window glass.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

FIG. 3 shows a first embodiment, in which the side frame 1 is roll-formed from a single plate and has a substantially square-shaped closed cross-section.

This side frame 1 has a window glass 2
The window glass 2 is coated with a structural adhesive such as a urethane sealer or a thiol sealer on one side. It is glued by 3.

It is located almost on the same surface as the adhesive surface 1a for bonding this window glass 2, and this adhesive surface 1a
The welding flange 4 of the side frame 1, which is formed close to the end face 2b of the side edge of the window glass 2, has a flange 4a on the side opposite to the window glass 2, which is formed close to the end face 2b of the side edge of the window glass 2. The outer surface 2c of the window glass 2 is erected toward the outside of the vehicle so as to be substantially parallel to the thickness direction of the window glass 2.
A molding locking part 51 is formed by folding back at approximately the same height as the flange 4a, and the end of the flange 4a is overlapped with the window glass side flange 4b and fixed by spot welding.

The window molding 61 has a substantially inverted "U" shape in cross section, and a hook-shaped locking pawl 71 is provided at one free end thereof.

The locking claw 7 of this window molding 61
By pushing one part into the molding locking part 51 formed on the side frame 1, the locking claw 7 of the window molding 61 is inserted into this molding locking part 51.
1 will fit, and this window molding 61 can be attached.

That is, since the window molding 61 can be attached by fitting and engaging, a fastener which is a separate member for attaching the window molding 61 can be made unnecessary.

FIG. 4 shows a second embodiment, in which the side frame 1 is made of two plate materials 11 and 12, and the plate materials 11 and 12 are joined in the middle to form a substantially square-shaped structure. It has a closed cross-sectional shape.

Similar to the first embodiment described above, this side frame 1 extends along the side edge of the window glass 2, and one side faces the inner surface 2 of the window glass 2.
A window glass 2 is bonded to one side of the window glass 2 with a structural adhesive 3.

The welding flange 4 of the side frame 1, which is located almost on the same plane as the adhesive surface 1a of the window glass 2 and is formed close to the end surface 2b of the side edge of the window glass 2, is connected to the window glass side flange 4b. is erected toward the outside of the vehicle so as to be substantially parallel to the end surface 2b of the side edge of the window glass 2, and is folded back at a position substantially at the same height as the outer surface 2c of the window glass 2 to form a molding locking portion 52. ing.

The window molding 62 has a substantially inverted "U" shape in cross section, and an arcuate protrusion 72 provided at one free end allows the window molding 62 to engage the molding locking part 62.
It can be attached and attached by fitting it.

According to these embodiments, fasteners such as bolts B and nuts N and retainers R, which were necessary for attaching the window moldings 61 and 62 of the backdoor D, are no longer required, which is advantageous in terms of cost.

[Effect of idea]

According to the present invention, the nut of the fastener that protrudes from the back side of the side frame is eliminated, so when the back door is opened, the appearance of the back side of the back door becomes much better.
