Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile roof molding mounting structure.

[0002]

2. Description of the Related Art In a vehicle, as shown in FIG. 2, a roof side rail 3 is provided so that an outer panel 4 of a roof side rail 3 which is a roof side constituent member is substantially above a side portion of the roof panel 1. It is known that it is arranged on the outside of the vehicle to enlarge the upper space of the vehicle compartment.

Specifically, as shown in FIG. 6, the upper edge portion of the outer panel 4 of the roof side rail 3 is step-formed to form a substantially horizontal flange 5A, while the side edge portion of the roof panel 1 is formed. Is formed into a stepped shape downwards to form a substantially horizontal flange 2
A is formed, and these flanges 5A and 2A are superposed on the upper edge of the inner panel 6 of the roof side rail 3 and joined by spot welding, and the connecting portion between the roof panel 1 and the roof side rail 3 extends in the front-rear direction. The connecting portion is offset below the general surface of the outer panel 4 of the roof panel 1 and the roof side rail 3 so that the groove portion 7A has an existing U-shaped cross section, and the roof molding 8 is attached to the groove portion 7A. By doing so, the roof panel 1 and the roof side 3 are configured so as to have a sense of unity.

In addition, as shown in FIGS. 5 and 7 and 8, the front pillar 9 and the connecting portion between the roof panel 1 and the roof side rail 3 are hidden by the door sash 10 to be exposed to the outside of the vehicle. The connecting portion between the upper edge portion of the outer panel 12 of the rear pillar 11 which is a rear roof side constituent member and the flange 2A of the roof panel 1 is similar to the connecting portion between the roof panel 1 and the rear pillar 11 of the vehicle shown in FIG. There is also one in which the roof panel 1 and the rear pillar 11 have a sense of unity by mounting the roof molding 8 in the groove 7A having a U-shaped cross section.

In any of these, as a mounting structure of the roof molding 8, as shown in FIGS. 6 and 7, a plurality of clips 16 are provided on the groove bottom of the groove portion 7A at an appropriate interval in the front-rear direction and the double-sided adhesive tape 17 is provided. Adhesively fixed with, etc., these clips 16
The roof molding 8 having a C-shaped cross section is fixedly attached to and fixed so that the lips 8a on both side edges of the roof molding 8 are closely arranged to the open groove edge of the groove portion 7.

[0006] This similar structure is, for example, the actual Kaihei 2-343.
63, Japanese Utility Model Laid-Open No. 3-77745, and the like.

[0007]

In the structure shown in FIG. 6, since the clip 16 is adhesively fixed on the flange 2A to be spot-welded, not only the adhesion becomes unstable due to the influence of welding distortion, but also the adhesiveness becomes unstable. Due to the influence of the welding distortion, the roof molding 8 may be bent between the clips 16 and may be undulated in the front-rear direction to deteriorate the appearance.

It is necessary to apply a paint seal 18 to the end portion of the flange 2A as a sealing material. The end portion of the flange 2A is located at the corner of the groove bottom of the groove portion 7A on the roof side rail 3 side for work. There is also a problem that it is difficult to perform the sealing material filling work because it becomes a blind spot for the person.

Further, since the groove 7A has a U-shaped cross section and the flange 2A and the flange 5A are superposed substantially horizontally and spot-welded, should water intrude from the end portion of the flange 2A, the intruding water May penetrate the overlapping portion of the flange 2A and the flange 5A and enter the interior of the vehicle.

On the other hand, in the structure shown in FIGS. 7 and 8, the same applies to the connecting portion between the rear pillar 11 and the roof panel 1 shown in FIG. Since the inner panel 14 of the rear pillar 11 is inclined and arranged toward the rear roof rail (not shown) on the lower side, the flange 2A and the flange 13A at the upper edge portion of the outer panel 12 of the rear pillar 11 are arranged in the direction perpendicular to the surface. Since the spot gun 20 is abutted and welded, it is necessary to form a large working hole 19A in the inclined portion of the inner panel 14 so as not to interfere with the spot gun 20.
The rigidity of the connecting portion between the rear pillar 11 and the roof panel 1 is reduced.

Further, the outer panel 12 of the rear pillar 11
Since the upper edge of the step is formed substantially vertically in a stepped manner, an acute-angled inverse portion is generated and the formability deteriorates.
If the angle of the corner portion C where the inverse portion and the front edge portion of the outer panel 12 join together become acute, the formability is further deteriorated. Therefore, the inclination of the front edge of the corner portion C is loosened. Since it is necessary to open and adjust the angle of the portion C, there is a problem that the degree of freedom in modeling is narrowed.

Therefore, the present invention neatly arranges the roof molding,
Further, the present invention provides a roof molding mounting structure that can be securely mounted, the sealing property can be improved, and the strength around the roof side can be improved and the flexibility of molding can be increased. .

[0013]

According to the first aspect of the present invention, the flanges on both side edges of the roof panel are joined to the outer panel of the roof side constituent member so that the front and rear portions are connected to the connecting portion between the roof panel and the roof side constituent member. In a structure in which a groove portion extending in the direction is formed and a roof molding is attached to the groove portion,
The outer panel upper edge portion of the roof side constituent member is concavely formed into a V-shaped cross section, and the flange of the roof panel side edge portion is joined to the upwardly inclined flange to form the groove portion with a V-shaped cross section. Roof moldings are bonded and fixed to the inclined wall surfaces on both sides of the groove.

According to a second aspect of the present invention, the ends of the flange on the side edge of the roof panel are aligned with the top of the V-shaped cross section of the groove, and the ends are filled with the sealing material.

According to a third aspect of the present invention, the inclined wall on the roof center side of the groove portion is formed substantially parallel to the inner panel of the roof side constituent member disposed below the groove portion, and the groove portion of the inner panel is formed. A working hole is provided in a portion corresponding to the inclined wall on the center side of the roof.

[0016]

According to the first aspect of the present invention, the roof molding has two surfaces, that is, the inclined wall surface on the roof center side of the groove portion having a V-shaped cross section, which is joined to the flange on the side edge of the roof panel, and the smooth inclined wall surface on the roof side component member side. Since the adhesive is fixed, the adhesive is not stably lifted up, and therefore, wavy deformation can be eliminated and the device can be mounted in an orderly manner, and the appearance can be further improved.

Further, since both sides of the roof molding are slidably adhered to the inclined wall surfaces on both sides of the groove having the V-shaped cross section, there is no displacement of the roof molding in the vehicle width direction. The appearance and quality can be improved without generating a gap between the groove and the edge of the groove.

Further, since the joint between the flange on the side edge of the roof panel and the flange of the roof side constituent member is inclined upward, invading water never penetrates through this joint and enters the passenger compartment. The sealability can be further improved.

According to the second aspect of the present invention, the flange end on the side edge of the roof panel is located at the center top of the V-shaped groove that is visible to the operator, and the top is used as a work guide for filling the sealing material. Therefore, the work of filling the sealing material can be easily performed, and the work can be reliably performed without causing defective filling or protruding of the sealing material.

According to the third aspect, the inclined wall on the roof center side of the groove formed by joining the flanges is formed substantially parallel to the inner panel of the roof side constituent member, and the inclined wall is formed on the inner panel. Since the working hole is formed in the portion corresponding to, the spot gun that comes into contact with the inclined wall in the direction perpendicular to the surface can be inserted into the working hole of the inner panel in the direction perpendicular to the inner panel, and therefore, The working hole can be formed to have a diameter as small as possible, and a decrease in strength and rigidity of the roof side portion can be suppressed to be small.
