Description

[Detailed Description of the Invention] This invention relates to an improvement in the structure for attaching the end of a drain hose in a sliding sunroof vehicle or the like.

For vehicles with a sliding sunroof, see Figure 1A.

At each corner of the sunroof frame 1 as shown in B,
Drain hose 2, 2 through the drain pipe to drain water. ... are connected, and the front side drain hose 2 passes through the front pillar 3 to the inside of the front fender 4, and the rear side drain hose 2 passes from inside the rear pillar 5 to the rear fender as shown in Fig. 2. 6
rainwater is drained outside the vehicle through the inside of the vehicle.

The end of the rear drain hose 2 is secured to, for example, a hanging portion 8a of the rear floor 8 by a grommet 1-7 as shown in FIG.

However, in the conventional mounting structure using a grommet as described above, the positioning of the end of the drain hose is uncertain, the amount of the drain hose protruding outside the vehicle is large, and it is likely to interfere with other parts such as the exhaust pipe 9, etc. In addition, since the grommet L-7 only held the end of the drain hose by friction, there was a risk that the drain hose would be pulled and come off when loading and unloading cargo into the 1st rank. .

In order to solve this problem, it is conceivable to connect a bulge-shaped pipe 1 to the end of the drain hose 2 as shown in Fig. 5, but this increases the number of parts and is not suitable for practical use. It's hard to say.

This idea was created by focusing on the above problems, and the end of the drain hose has a stepped part with a large outer diameter, which can be engaged with a mounting hole provided in a panel of the vehicle body. A grommet is provided with a lip that can come into contact with the outer periphery of the hose on one side of the ring-shaped attachment part, and a stopper part that projects inward is formed on the inner periphery of the end opposite to the lip. By inserting and fixing the end of the hose from the lip forming side, the end of the drain hose can be positioned securely, the amount of protrusion of the end of the hose to the outside of the vehicle is small, and the hose tends to be inserted into the grommet. To provide a structure for attaching the end of a drain hose, which can be securely locked so that it does not easily come off.

Embodiments of this invention will be described below based on the drawings.

FIG. 3 shows an embodiment of the present invention, where 8 is a rear floor panel, 7 is a rubber grommet attached to this rear floor panel 8, and this grommet 7 is inserted into a mounting hole 10 provided in the rear floor panel 8. It consists of a ring-shaped attachment part 7b having an engaging groove 7a that can be fitted, and a nozzle-shaped lip 7C formed on the inside (left side in the figure) of this attachment part 7b, and an end opposite to the lip 7C. A plurality of protruding stopper portions 7d projecting inward are formed on the inner peripheral edge of the portion.

Further, 2 is a drain hose, and this drain hose 2 has an annular stepped portion 2a having a larger diameter than other parts formed on the outer periphery of the end portion, and the end portion of this drain hose 2 is attached to the grommet 7 with a lip 7C. It can be attached to the rear floor panel 8 by inserting it from the side.

That is, as shown in FIG. 4, the end of the drain hose 2 is first engaged with the grommet 7, and then the mounting portion 7b of the grommet 7 is engaged with the mounting hole 10 of the floor panel 8 for installation.

At this time, the grommet 7 is engaged with the drain hose 2 by bending the lip 7C inward as shown in the figure, and then by sliding the hose a little back and forth, the grommet 7 can be connected as shown in Figure 3A. The lip 7C is restored outward.

The drain hose inserted into the grommet 7 in this way has its end abutted against the collar 7d on the inner periphery of the grommet 7, making it possible to securely place the drain hose in an upright position.
Since the drain hose 2 is located inside the floor panel 8, the amount of protrusion of the drain hose 2 to the outside of the panel is small, and since the stepped portion 2a is located at the end of the hose, friction with the lip 7C becomes large, making it difficult for the drain hose to come off.

Note that the lip 7C may be formed in advance so as to face the inside of the grommet 7, as shown in FIG.

In this way, the stepped portion 2a of the drain hose 2 is locked to the tip of the lip 7C, making it more difficult for the horn to come off.

As explained above, this invention forms a stepped part with a large outer diameter at the end of the drain hose, and also has a ring-shaped mounting part that can be engaged with a mounting hole provided in the panel on which the drain hose is attached. , the end of the drain hose is attached to a grommet consisting of a lip that can come into contact with the outer periphery of the hose, which is provided on one side of the attachment part, and a stopper part that is formed on the inner periphery of the end opposite to this lip. Since it is configured to be inserted and fixed from the lip forming area, the end of the drain hose can be securely positioned by the stopper, and since the lip is located inside the panel, the amount of protrusion of the end of the drain hose is also reduced. There is no interference with other parts, and the step at the end of the drain hose prevents the hose from coming off.
