Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a mounting structure of a roof molding provided on a roof of an automobile.

2. Description of the Related Art A mounting structure of a roof molding provided on a roof in order to improve the aesthetics of a sheet metal structure terminal or a seam of an automobile is disclosed in, for example, Japanese Utility Model Laid-Open No. 63-112154, and as shown in FIG. A groove 14 is formed by recessing the joint 13 between the outer end 11a of the roof panel 11 and the upper end 12a of the quarter panel 12 from the general surfaces of the panels 11, 12, and a bottom surface 14a and a side surface in the groove 14. 14b and a clip 16 glued with adhesives 15, 15, respectively
In some cases, the molding 17 is locked to close the opening of the groove 14.

In this molding mounting structure, since the clip for attaching the molding is adhered to the bottom and side surfaces in the groove,
The mall can be held firmly. However, since the clips are adhered to the bottom and side surfaces in the groove, there is a problem that the work of attaching the molding is troublesome.

Therefore, as shown in FIG.
21a and the inner end 22a of the side rail outer panel 22 are overlapped and connected, and a clip for mounting a molding is provided in a connection recess 24 formed by recessing the connection portion 23 from the general surface of both panels 21 and 22.
It has been proposed to use a thermosetting adhesive tape 26 to heat-melt the tape 26 by heating at the time of painting and to harden the tape 26 by curing.

(Problems to be Solved by the Invention) According to the above conventional technique, a clip is adhered by a thermosetting adhesive tape, and further, the tape is melted and softened by heating at the time of painting and hardened by hardening. Can be. However, when the tape is melted and softened by heating, the clip tilts down due to its own weight as shown by a dashed line 25 'in FIG. 6, and when the molding is fixed, the molding is twisted and deformed into a waving shape. There is a problem such as being unable to fully perform the decoration function when mounted.

Accordingly, an object of the present invention is to provide a roof molding mounting structure capable of sufficiently performing a decorative function by preventing deformation of a molding such as twisting and waving without the clip being tilted even by heating. is there.

(Means for Solving the Problems) The roof molding mounting structure according to the present invention that achieves the above object includes an outer end of a roof panel and an inner end of a side rail outer panel which are overlapped and connected to each other. In a roof molding mounting structure in which a molding is attached via a clip along a coupling recess in a coupling recess formed by being recessed from a general surface, along a joint between an outer end of a roof panel and an inner end of a side rail outer panel. A clip having a thermosetting sealing material applied thereto, and a clip extending from a clip body having a locking portion for attaching the molding and a leg portion adhered to the inner surface of the coupling recess, and having a support portion having a top portion reaching the sealing material; And a thermosetting adhesive tape for fixing the leg portion of the clip to the inner surface of the coupling recess.

(Function) When the tape is heated and cured by the thermosetting adhesive tape and the leg of the clip is adhered to the joint concave portion, the top of the leg is supported against the sealing material even if the tape is melted and softened by heating. Because the clip is prevented from tilting beforehand, the clip is provided in a normal state, and even if the mall is fastened, the mall will not be twisted or deformed in a waving manner, and the decoration function of the mall will be sufficient. It can be used and the mall can be firmly attached.

(Embodiment) An embodiment of a roof molding mounting structure according to the present invention will be described below with reference to FIGS.

FIG. 4 is a perspective view of an automobile showing an application portion of the present invention. FIG. 1 is an enlarged sectional view taken along line II of FIG.
The figure is an exploded perspective view.

In the drawing, reference numeral 1 denotes a molding provided from the front to the rear so as to cover a joint between an outer end of a roof panel 2 and an inner end of a side rail outer panel (hereinafter referred to as an outer panel) 3 on the side of the roof of the automobile.

Outer end 2a of roof panel 2 and inner end of outer panel 3
3a are overlapped, the overlapped portions are joined by spot welding or the like, and the joined portions are recessed from the general surfaces of the roof panel 2 and the outer panel 3 along the longitudinal direction of the vehicle body to form a joint recess 4.

Outer end of roof panel 2 forming the bottom of coupling recess 4
The tip 2b of 2a is bent upward and the outer edge of the roof panel 2
A thermosetting sealing material 5 is applied along a joint between the outer panel 3 and the inner end 3a of the outer panel 3. As shown by a solid line a in FIG. 3, the thermosetting sealing material 5 is made of, for example, a vinyl chloride resin material which is cured by heating.

Outer end of roof panel 2 forming the bottom of coupling recess 4
An appropriate number of clips 6 are adhered to their legs 6b by a thermosetting adhesive tape 7 on 2a. Thermosetting tape 7
Is a tape using, for example, an oligomer-type pressure-sensitive adhesive which gradually softens as it is heated, melts and softens, then hardens again and adheres firmly as shown by the dashed line b in FIG.

In addition to the legs 6b adhered to the bottom of the coupling recess 4 by the thermosetting tape 7, the clips 6 are provided with locking portions 6c, 6c for attaching the molding 1 and the projections 6d abutting on the sides of the coupling recess 4. , 6d
And a support leg 6e projecting downward from the clip body 6a. The length 1 of the supporting legs 6e, 6e projecting downward from the clip body 6a is such that the leg 6 of the clip 6 is attached to the bottom of the coupling recess 4 by a thermosetting tape 7
When bonded, the top portions 6e 'and 6e' are inserted into the thermosetting sealing material 5 by 2 to 3 mm.

The protrusions 6d, 6d of the clip 6 configured as described above are positioned by contacting the side portions of the coupling recess 4 and
e, 6e are inserted into the thermosetting sealing material 5, and the leg 6b is inserted.
Is adhered and fixed to the outer end 2a of the roof panel 2 forming the bottom of the coupling recess 4 by a thermosetting tape 7.

After attaching the clip 6 in the coupling recess 4 formed by the roof panel 2 and the outer panel 3 in this manner,
In the paint baking process, the thermosetting sealing material 5 and the thermosetting adhesive tape 7 are heated at about 140 ° C. for a predetermined time or more.
Is hardened, and the clip 6 is firmly fixed in the coupling recess 4 formed by the roof panel 2 and the outer panel 3.

At this time, the temporary thermosetting adhesive tape 7 melts and softens as the temperature increases, and the adhesive strength of the clip 6 decreases. However, since the thermosetting sealing material 5 that has been cured to some extent supports the legs 6e, 6e, The clip 6 is mounted in the coupling recess 4 in a normal state without tilting and falling.

Therefore, by engaging the engaging portions 1a, 1a of the molding 1 with the engaging portions 6c, 6c formed on the upper portion of the clip 6,
The molding 1 is firmly attached to the joint concave portion 4 along the joint concave portion 4 in the front-rear direction of the vehicle body without being deformed in a waving manner.

Note that the tops 6e 'of the legs 6e, 6e formed on the clip 6,
6e 'is retained in the sealing material 5 without penetrating to the bottom of the thermosetting sealing material 5, so that the same sealing performance as in the related art is ensured.

(Effect) According to the roof molding mounting structure of the present invention, when the thermosetting adhesive tape is heated and cured to attach the legs of the clip to the coupling recesses, the legs are heated and melted even if the tape is melted and softened. The top of the abutment is supported against the thermosetting sealing material to prevent the clip from tilting, the clip is provided in a normal state, and the mall can be fastened without inducing twisting and banging deformation, and decoration. The function is sufficiently exhibited, and the appearance quality of the automobile can be expected to be improved. Further, in combination with the simple structure in which the support portion is provided on the clip, the practical effect is increased.
