Description

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 an automobile, as shown in FIG. 2, a roof side rail 4 is arranged outside the vehicle so that an outer side 5 of the roof side rail is located on a substantially extended side of a roof panel 1. It is known that the upper space of the room is enlarged.

Specifically, as shown in FIG. 3, a roof side rail outer 5 and a roof side rail 4 which form a roof side rail 4 having a closed cross section are formed by bending and bending flanges 2 on both side edges of a roof panel 1. The connection is made by spot welding by superposing on the joint flange portion 7 on the roof side with the inner 6 so that the connecting portion between the roof panel 1 and the roof side rail 4 becomes the groove portion 9 extending in the front-rear direction. By offsetting the connection portion below the general surface of the roof panel 1 and the roof side rail outer 5, and by mounting the roof molding 10 in the groove portion 9,
The roof panel 1 and the roof side rail 4 are configured so that they can be integrated.

As the mounting structure of the roof molding 10, as shown in FIG. 3, a plurality of resin T studs 12 are adhered and fixed to the groove bottom of the groove portion 9 in the front-rear direction at appropriate intervals, and these T studs are attached. A roof molding 10 having a substantially C-shaped cross section is fixedly attached to 12 and lips 11 on both side edges thereof are formed on a vertical wall 3 of a roof panel 1 and a vertical wall 8 of a roof side rail outer 5 which form a side wall of a groove 9. Closely arranged,
As shown in FIG. 4, inverse portions 13 and 14 are formed on the upper portions of the vertical walls 3 and 8 to squeeze the upper portion of the groove portion 9 to form a substantially T-shaped portion.
It is known that the leg portion 16 of the roof molding 15 having a V-shaped cross section is attached to the inverse portions 13 and 14 by engaging them. (See Japanese Utility Model Publication No. 3-77745 and Japanese Utility Model Publication No. 3-45348).

[0005]

According to the former structure,
A plurality of T studs 1 on the flange 2 of the roof panel 1
2 is adhered and fixed, and the roof molding 1 can be attached through the T stud 12 with the roof panel 1 as an attachment reference. Therefore, the dimensional variation in the vehicle width direction between the roof molding 10 and the groove portion 9 can be eliminated from the roof side rail outer 5. It can be aggregated on the vertical wall 8 side.
It can be absorbed by the lip 11 which is in close contact with.

However, since the T-stud 12 is adhesively fixed to the central portion of the flange 2 which is spot-welded,
There is a possibility that the height dimension of the T studs 12 varies due to the influence of welding distortion, the roof molding 10 is bent between the T studs 12, and the roof molding 10 is waved and deformed in the front-rear direction to deteriorate the appearance.

On the other hand, in the latter structure, since the roof molding 15 is attached across the inverse portion 13 of the vertical wall 3 of the roof panel 1 and the inverse portion 14 of the vertical wall 8 of the roof side rail outer 5, the roof molding 15 is engaged. The dimensional variation in the vehicle width direction between the groove 15 and the groove portion 9 appears as a gap between both side edges of the roof molding 15 and the upper side edges of the groove portion 9 and impairs the appearance.

Further, due to molding error, assembly error, etc.,
If the space between the narrowed portions between the inverse parts 13 and 14 is too narrow, it becomes difficult to insert and lock the roof molding 15, and if the space is too wide, the roof molding 15 easily falls off. It causes a problem that ends up.

Further, a paint seal 17 is applied as a sealing material to the parting portion between the end of the flange 2 of the roof panel 1 and the vertical wall 8 of the roof side rail outer 5, so that water can enter from the joint portion of the flange 2. However, since the upper portion of the groove 9 is squeezed by the inverse portions 13 and 14 as described above, it is difficult to apply the paint seal 17 and it is difficult to see the paint seal 17, so that the paint seal is not visible. It is difficult to confirm the coated state of No. 17 and it is easy to induce a defective seal.

Therefore, according to the present invention, the roof molding can be mounted in the groove formed in the connecting portion between the roof panel and the roof side rail without damaging the appearance, and the quality and reliability can be further improved. (EN) Provided is a roof molding mounting structure which can be carried out.

Grooves 9 are superposed on the flange portion 7 and joined by spot welding to form a groove portion 9 extending in the front-rear direction at a connecting portion between the roof panel 1 and the roof side rail 4.

The end of the flange 2 is bent upward to form a positioning edge 20 which engages with a bottom side edge of a roof molding 24, which will be described later. The positioning edge 20 and the roof side rail outer 5 are formed. A sealing material filling groove 21 is formed between the vertical wall 8 and the paint seal 17 with a sealing gun (not shown).

A fastener 22 made of a resin material is adhesively fixed to the vertical wall 3 of the roof panel 1 with an adhesive material, for example, a double-sided adhesive tape 23.

The fastener 22 is formed in a substantially U-shaped cross section, and its lower edge is positioned on the flange 2 in the vicinity of the vertical wall 3 so as to be in contact therewith.

A roof molding 24 is fixedly attached to the fastener 22, and the groove 9 is hidden by the roof molding 24.

The roof molding 24 is made of an elastic material such as rubber or resin, and one side of the roof molding 24 has a leg piece 2 which is engaged with the fastener 22.
5 is formed so that a groove 25a is formed between the half molding 24 and the base body 24a of the half molding 24, and lips 26 and 27 that project in a substantially horizontal direction are formed on both side edges of the upper portion.

Further, a hollow portion 28 opening to the leg piece 25 side is formed near the bottom surface of the roof molding 24, and the roof molding 2 is formed.
4 is formed so as to be connected to the base body 24a of the roof molding 24 on the side opposite to the leg piece 25 side, and the bottom surface of the roof molding 24 is bonded with an adhesive material, for example, the double-sided adhesive tape 23 in the same manner as the flange 2 It is fixed on the top by adhesive.

In the roof molding 24, the leg pieces 25 are inserted into the substantially U-shaped portion of the fastener 22 and pushed, so that the ends of the fastener 22 are grooved between the leg pieces 25 and the base 24a of the roof molding 24. Entering 25a, the leg piece 2
5 is attached to the fastener 22, the bottom surface of the roof molding is adhesively fixed on the flange 2 by the double-sided adhesive tape 23, and the bottom side edge engages with the positioning edge 20 to fix the mounting position in the vehicle width direction. , The lip 26 is in close contact with the upper edge of the vertical wall 3 of the roof panel 1, while the lip 27 longer than the lip 26 is the vertical wall 8 of the roof side rail outer 5.
The groove 9 is concealed in close contact with a lower position than the upper edge thereof.

According to the structure of the above embodiment, the roof molding 24 is attached by the fastener 22 and the double-sided adhesive tape 23 with the roof panel 1 as a reference.
The variation in the vehicle width direction dimension between the roof molding 24 and the groove portion 9 can be concentrated on the vertical wall 8 side of the roof side rail outer 5, and the variation in this dimension is caused by the elastic deformation of the lip 27 that is in close contact with the vertical wall 8. Since there is no gap between the lips 26, 27 and the upper edge of the groove portion 9, and since the lip 27 is closer to the lower position than the upper edge of the vertical wall 8, Even if the lip 27 bends and deforms, it is hardly noticeable and the appearance can be significantly improved.

The lower edge of the fastener 22 has a vertical wall 3

Since it is possible to reliably prevent the formation of a gap and is located at the base of the positioning edge 20 having high rigidity, there is no influence of distortion due to spot welding of the flange 2.

On the other hand, the seal material filling groove 21 formed between the positioning edge 20 and the vertical wall 8 of the roof side rail outer 5 is filled with the paint seal 17 as a sealing material. It can be effectively used as a guide for an outer sealing gun, and the sealing gun can be slidably contacted with the positioning edge 20 to fill the paint seal 17 into the sealing material filling groove 21. Therefore, the filling work of the paint seal 17 is facilitated. It can be carried out.

Also. Since the seal material filling groove 21 is formed to fill the paint seal 17 in this manner, a sufficient amount of the paint seal 17 can be secured and reliable sealing can be performed, and the paint seal 17 does not protrude. It also has a good appearance.
