Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a structure for arranging a drain hose for draining water from the sunroof of a vehicle with a sunroof.

(Prior art) Conventionally, in a vehicle with a sunroof, the
As shown in the figure, a water collection pan (not shown) is installed in the sunroof frame 2 around the sunroof 1 in order to drain water that enters from the seal surface around the sunroof 1 installed on the roof panel 0 to the outside of the vehicle. ) is connected to a flexible drain hose 3 such as a vinyl hose, and the drain hose 3 is extended through the inside of the pillar 4 to a drainage area such as a side sill or cowl side at the bottom of the vehicle body, and water is drained from there. However, in this case, the flexible drain hose 3 is inserted into the pillar 4 from the insertion opening 4a at the upper part of the pillar 4, which is assembled in advance with the pillar outer 5 and the pillar inner 6, so that the flexible drain hose 3 is disposed inside the pillar 4. The tip of the drain hose 3 may get caught on protrusions (not shown) such as the rigidity reinforcing member of the door hinge attachment part or the hinge attachment bolt that protrudes from the end of the reinforcing reinforcement 7 or inside the pillar 4. It is difficult to insert the parts smoothly, and in particular, since such work is carried out on an assembly line as an assembly line, the work efficiency is poor.

Therefore, as described in Japanese Utility Model Application Publication No. 58-136875, the protrusion inside the pillar is covered with a guide cover, and the tip of the drain hose is guided along the guide cover when the drain hose is inserted, thereby making the insertion process easier. However, in recent years, the cross-sectional shape of the pillar has become narrower and narrower due to the expansion of interior space, miniaturization of vehicles, and the use of flat surface surfaces to improve aerodynamic characteristics. Another problem has arisen in that there is no room to install the guide cover etc. inside the pillar (particularly in the narrowed part above the waist part U near the joint with the cowl side panel).

(Purpose of the invention) This invention was made by paying attention to these conventional problems, and its purpose is to construct the part of the drain hose that is installed inside the pillar with a rigid tube, and to A tube is previously assembled into the pillar and fixed to the inner surface thereof, while a working hole is formed at a position below the waist of the pillar inner, and the lower end of the rigid tube is extended to a position near the corresponding position of the working hole,
By connecting a flexible tube from the lower end to the drainage part, it is possible to omit the work of inserting the drain hose into the pillar, improving work efficiency on the assembly line, and also to improve work efficiency in narrow pillars. The object of the present invention is to provide a drain hose arrangement structure that can be fully applied.

(Structure of the device) In order to achieve the above object, in this device, at least the portion of the drain hose disposed in the narrowed portion above the waist portion inside the pillar is formed by a rigid tube, and While the rigid tube is fixed to one inner surface of the pillar outer, a working hole is formed below the waist of the pillar inner, and the lower end of the rigid tube is extended to the vicinity of the corresponding position of the working hole, and the drain is drained from the lower end. A pillar was constructed by connecting flexible tubes up to the end.

(Example) This invention will be explained below based on the drawings.

5 to 7 show a drain hose arrangement structure for a vehicle with a sunroof according to this invention. To explain its structure, Fig. 5 shows the disassembled state of the front pillar 4 of a vehicle with a sunroof, and similarly to Fig. 1, the drain hose runs from around the sunroof through the inside of the front pillar 4 to the side sill. 3 is extended.

The part of the drain hose 3 located in the narrowed part above the waist part U is constituted by a rigid pipe 3a made of a highly rigid material such as a steel pipe or a metal pipe.
This rigid tube 3a is assembled into the front pillar 4 before it is assembled.

Below, the front pillar 4 incorporating the rigid tube 3a
The configuration of is explained below. As shown in Figure 5,
The front pillar 4 includes a pillar outer 5 having a narrow side surface shape, and a pillar inner 6 formed by joining the upper end edge of the pillar inner lower 6a, which is integrally formed with the dash side 8, and the lower end edge of the pillar inner upper 6b. A rigid tube 3a extending from the upper end to the lower end is disposed on the inner surface of the pillar inner upper 6b in the narrowed part above the waist part U where the cross-sectional shape becomes narrow.
As shown in FIG.
It is fixed to the inner surface by welding etc. Rigid tube 3
The upper end of a protrudes outward from the insertion opening 4a formed at the upper end of the pillar inner upper 6b,
Also, the lower end of the rigid tube 3a is a pillar inner top 6b.
It extends to a working hole 9 formed at the lower end of the hole.

On the inner surface of the lower end of the pillar inner lower 6a, the front end of a side sill 10 extending in the longitudinal direction of the vehicle is fixed by spot welding at the lower end edge, and a drain port 11 bored in the upper surface 10a of the side sill 10 is connected to the front end of the side sill 10 extending in the longitudinal direction of the vehicle. The lower end of the vinyl hose 3b whose upper end is connected to the lower end of the rigid tube 3a is inserted.

As described above, the flanges on both sides of the pillar outer 5 are brought into close contact with the flanges on both sides of the pillar inner 6 to which the rigid tube 3a is fixed in advance on the inner surface, and are welded. is assembled. At this time, the rigid tube 3a incorporated inside the front pillar 4 also functions as a reinforcing material to strengthen the rigidity of the front pillar 4.

As shown in FIG. 6, the upper end of the rigid tube 3a extending from the insertion opening 4a at the upper end of the front pillar 4 is connected to a water collecting plate (not shown) provided around the sunroof via a vinyl hose 3c. ) is connected to the drain pipe 12.

Water that has entered the inside of the sunroof from around the sunroof is collected in a water collecting tray (not shown), flows from the drain pipe 12 into the side sill via the vinyl hose 3c, the rigid tube 3a, and the vinyl hose 3b, and then flows into the side sill. It is discharged to the outside through the hollow interior of.

In the above embodiment, the rigid tube 3a is connected to the pillar inner 6
Although the case where the rigid tube 3a is fixed to the inner surface of the pillar outer 5 has been described, the rigid tube 3a may be fixed to the inner surface of the pillar outer 5, and its length does not end at a position near the waist portion but extends to a position near the side sill. Good too.

In addition, the drain hose 3 is attached to the front pillar 4
It may be passed through not only the interior but also the center pillar, rear pillar, etc.

(Effects of the invention) As explained above, according to this invention,
The portion of the drain hose that is disposed inside the pillar is formed of a rigid tube, and the rigid tube is fixed to the inner surface of one of the pillar inner and pillar outer, while a working hole is formed at a position below the waist of the pillar inner, and the rigid tube is fixed to the inner surface of one of the pillar inner and pillar outer. The lower end of the pillar is extended to the vicinity of the corresponding position of the working hole, and the pillar is assembled by connecting the pillar inner and pillar outer together by connecting a flexible tube from the lower end to the drainage part. The pillar is manufactured as a single unit with a rigid pipe that forms part of the drain hose installed in advance, and on the assembly line, it is only necessary to assemble the pre-assembled pillar as a single unit to other structural members.
Since there is no need to insert a flexible drain hose into the assembled pillars as in the past, work efficiency on the assembly line is improved.

In addition, a working hole is provided at an appropriate position, and a drain hose (rigid tube) is extended to the position corresponding to the working hole, so that the lower end of the rigid tube is Flexible tubes such as vinyl hoses can be easily connected, making it easier to assemble and minimizing cost.

Furthermore, since the rigid tube itself is used as the drain pipe, it is sufficient to secure the necessary diameter for the drain, so the width of the pillar can be made as narrow as possible, making it suitable for various types of narrowed pillars. can.

Furthermore, since only the narrowed portion of the pillar is effectively reinforced with a drain pipe made of a rigid tube, it has a great practical effect of minimizing costs.
