Concealed drainage structure.

[Prior Art] Generally, a body of a vehicle is provided with a drainage structure for guiding rainwater to the outside of the vehicle.

For example, FIG. 7 is a rear side perspective view of a roof portion of a vehicle body having a conventional drainage structure in a vehicle having a back door, and as shown in the figure, a side portion 1a and a rear end portion of a roof panel 1 are shown. A drip channel 12 is provided around 1b, and rainwater dropped on the roof panel 1 flows into the drip channel 12, passes through the drip channel 12, and is formed in the corner portion 12a of the drip channel 12 and the drip channel 12. From the bent part not shown,
It is discharged to the outside through the rear surface of the body panel and the surface of the rear door.

In addition, the drip channel 12 is provided on the side portion 1a of the roof panel 1.
There is also one in which the rear end of the drip channel 12 is opened rearward only in this case. In this case, the rainwater dropped on the roof panel 1 is discharged from the rear end open end of the drip channel to the body panel. It is discharged to the outside through the rear surface of.

[Problems to be Solved by the Invention] However, in the above-described conventional vehicle body drainage structure, rainwater that has dripped onto the roof panel 1 is discharged to the outside through the rear surface of the body panel and the surface of the rear door. The rear surface of the body panel and the surface of the rear door easily get dirty due to the circulation of rainwater. Especially, when there is a large amount of rain, the water overflows from the drip channel 12, and the rainwater flows out through a portion other than a predetermined position on the rear surface of the body panel or the rear door. As a result, it becomes easier for the body to get dirty due to rainwater,
It is not preferable because the appearance of the body is deteriorated.

Further, in recent years, the appearance has been improved by making the body a flash surface, but from such a viewpoint, there is a problem that the drip channel 12 impairs the appearance.

The present invention has been devised in view of such problems,
An object of the present invention is to provide a drainage structure for an automobile body, which is capable of preventing the dirt of the body from being damaged by rainwater from impairing its appearance and improving the appearance of the body itself.

[Means for Solving the Problems] Therefore, the drainage structure for an automobile body of the present invention is provided with a back door, and the drainage groove is directed rearward at the joint between the side portion of the roof panel and the inner edge portion of the rear side roof rail. In the automobile body in which the molding is formed and the molding is mounted so as to cover the drainage groove, the inner edge portion of the rear pillar coupled to the rear side roof rail extends downward so as to be continuous with the drainage groove. A groove having a U-shaped cross section is formed, and a drip channel formed along the rear edge of the roof panel is formed so as to communicate with the groove together with the drain groove, and a side edge of the back door is formed. A part is configured to cover the groove when the back door is closed.

[Operation] In the above-described drainage structure for a vehicle body of the present invention, the rainwater dropped on the roof panel, the rainwater dropped on the roof panel, the drain groove formed on the side of the roof panel and the rear edge of the roof panel. Flow into the drip channel formed along the inside of the drip channel, pass through the drain groove and the inside of the drip channel, and then flow into the groove formed on the inner edge of the rear pillar at the rear of the body. It is discharged downward.

[Embodiment] Hereinafter, a drainage structure of an automobile body as an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a main portion thereof, FIG. 2 is an exploded perspective view of the main portion, and FIG. The figure is first

As shown in FIGS. 1 and 3, a drainage groove 2 is formed in a vehicle longitudinal direction at a joint portion between both side portions 1a of a roof panel 1 on both sides of a roof portion of an automobile body and an inner end portion 3a of a rear side roof rail 3. Is formed toward. Here, the drainage groove 2 is formed so as to become gradually deeper toward the rear of the body, and the upper surface thereof is covered with the molding 4.

As shown in FIG. 3, the molding 4 includes a roof panel 1
The rear side roof rail 3 is mounted substantially flush with the surface of the rear side roof rail 3 and extends to the vicinity of the back door 8 at the rear end of the roof panel 1, as shown in FIGS. Also, mall 4
Between the roof panel 1 and the rear side roof rail 3 on both edges of the drainage groove 2 as shown by the arrow in FIG.
Holes 4a into which rainwater can enter are formed intermittently in the longitudinal direction.

Further, as shown in FIG. 1, the rear end portion of the roof panel 1
1b is formed in a flange shape, and the drip channel 5 is joined to the flange-shaped rear end portion 1b.

The drip channel 5 is joined to the flange-shaped rear end portion 1b of the roof panel 1 as shown in FIG.
It is joined to the rear side panel 6 together with the roof panel 1.

The rear side panel 6 is formed by integrally or continuously connecting the rear side roof rail 3 and the rear pillar 7, and a rear roof rail 9 as shown in FIG. A rear deck member (not shown) is connected to the lower portion of 7, and a rear opening 13 is formed by these members. The rear opening 13 is covered by the back door 8.

Then, as shown in FIGS. 2 and 6, the inner edge of the rear pillar 7 has a drain groove 2 at the inner edge 3a of the rear side roof rail 3.
A groove portion 7a extending downward from the body is formed so as to be substantially continuous with. On the other hand, the back door 8 is arranged so as to cover the groove portion 7a with its side edge portion 8a when closed, and is not exposed to the outside due to the groove portion 7a of the rear pillar 7 and the side edge portion 8a of the back door 8. A drainage channel 10 is formed.
A lower end (not shown) of the drainage channel 10 is opened downward.

A seal member 11 is mounted between the back door 8 and the body-side rear pillar 7 and rear roof rail 9.

On the other hand, cutouts 5a and 1c are formed in a portion corresponding to the rear end of the drain groove 3 in the overlapping portion of the drip channel 6 and the flange-shaped rear end 1b of the roof panel 1, and the cutout 5a is formed. The drainage channel 3 and the drainage channel 10 communicate with each other through the channels 1 and 1c.

Since the drainage structure of the vehicle body as one embodiment of the present invention is configured as described above, the rainwater that has fallen on the roof portion of the vehicle body can be discharged from the roof panel 1, the rear side roof rails 3, etc., through the holes 4a.
