Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a piping structure for a fuel filler hose for an automobile, and particularly to a structure suitable for an automobile in which a fuel tank is disposed under a rear seat.

Recently, in front engine-equipped front-wheel drive vehicles, as shown in Figs. 1 and 2, a rear seat 1
A structure in which the fuel tank 2 is placed at the bottom of the fuel tank is often adopted. In other words, the fuel tank 2 is placed below the rear floor panel 4 so as to be located at the center of both rear side members 3A, 3B. After the base end 5a of the filler hose 5 connected to the fuel tank 2 arranged in this manner protrudes toward the rear of the vehicle body, it passes under one of the rear side members 3A, is guided in the vehicle width direction, and is guided toward the wheel house. Usually, the tip portion 5c is raised upward from the internal space of the inner panel 6.

However, in such piping of the filler hose 5, the middle part 5b of the filler hose 5 extends for a considerable distance under the rear floor panel 4 in the transverse direction of the vehicle body, so it may be damaged by stones or other road protrusions while driving. There is a possibility that this part may be damaged, and conventionally, in order to prevent such damage, this part is covered with a protector. In addition, in the conventional structure,
In order to avoid interference between the filler hose 5 and the spare tire house 7 due to movement of the spare tire house 7 in the event of a rear-end collision, it is necessary to ensure a sufficient distance between the two, and the overhang of the rear floor panel 4 must be maintained. Problems arise when the amount becomes large.

In order to solve the above-mentioned filler hose piping problems, the present invention proposes shortening the filler hose and protecting it from road surface protrusions such as stones without using a special protector. The base end of the filler hose is pulled out from the outside of the fuel tank and is piped across the rear side member at a position behind the mounting bracket of the rear suspension rear wheel longitudinal positioning link to the vehicle body.

Embodiments of the present invention will now be described in detail with reference to FIGS. 3 to 10.

Figures 3 to 5 show a first embodiment of the present invention applied to a two-door car, with rear wheels 8 at both ends.
The position of both ends of the rear axle 9 in the longitudinal direction with respect to the vehicle body is regulated by positioning links 10 extending forward of the vehicle body. That is, as shown in the fourth and fifth figures, both ends of the positioning link 10 located below the outside of the rear side member 3A are attached to mounting brackets 11 and 12 located at the end of the rear axle 9 and at the front of the rear side member 3A. Each is rotatably connected.

According to the invention, the proximal end 5 of the filler hose 5
a is connected to the outer surface of the fuel tank 2 at a position above the middle part of the positioning link 10 when viewed from the rear of the mounting bracket 12, that is, from the side of the vehicle body, and the middle part 5b of the filler hose 5 is connected to the rear side member. 3A and the positioning link 10, and is guided to cross the rear side member 3A substantially horizontally outward in the vehicle width direction, and the tip portion 5c of the filler hose 5 is located above the side sill 13 located outside the rear floor panel 4. View from the front to the car body fender. Note that reference numeral 14 in FIGS. 3 to 5 is a handbrake wire, and this handbrake wire 14 is guided along the positioning link 10 by a clamp 15.

Since the first embodiment has the above structure,
Since the filler hose 5 is immediately led out from the outside of the fuel tank 2 toward the outside of the vehicle body, there is no interference between the spare tire house and the filler hose in the event of a rear-end collision or the like. And filler hose 5
Since the intermediate portion 5b of the filler hose crosses the rear side member 3A and the positioning link 10 and is pulled out from above the positioning link 10, the mounting bracket 12 and the positioning link 10 prevent protrusions from the road surface such as stones from being removed from the filler hose. Collision with 5 can be prevented.

6 to 8 show a second embodiment of the present invention suitable for a four-door vehicle, and the suspension structure of the rear axle 9 is exactly the same as that of the first embodiment. The middle portion 5b of the filler hose 5 in the second embodiment is positioned above the positioning link 10 and guided toward the rear of the vehicle body almost parallel to the link 10, and is positioned in the inner space of the wheel house inner panel 6. be. The tip end 5c of the filler hose 5 is raised from behind the rear axle 9 toward the outside of the vehicle body. According to such piping of the filler hose 5, it is possible to provide a fuel inlet at the rear of the rear fender of the vehicle body.
The present invention is suitable for use in a four-door vehicle.

9 and 10 show a third embodiment of the present invention for a four-door vehicle, and the arrangement of the filler hose 5 is exactly the same as in the second embodiment. The difference between the third embodiment and the second embodiment lies in the suspension structure of the rear axle 9, and in the third embodiment, the rear side member 3
A lower link 10A extending forward on the outside of the vehicle regulates the position of the rear axle 9 in the longitudinal direction, and an upper link 16 located diagonally on the inside of the rear side member 3A regulates the position of the rear axle 9 in the left-right direction of the vehicle. Regulations will be implemented. Therefore, in such a suspension structure, the rear side member 3
By leading out the filler hose 5 through the space between A and the lower link 10A, in addition to the same effect as in the second embodiment, interference between the filler hose 5 and the upper link 16 can be prevented, and the suspension It has the characteristic of increasing the degree of freedom in structure selection.

As is clear from the above description, according to the present invention, since the filler hose is drawn out from the outside of the fuel tank, there is no interference between the spare tire house and the filler hose, and the amount of overhang of the rear floor panel can be reduced accordingly. In addition, since the middle part of the filler hose in the present invention crosses the rear side member at a position behind the mounting bracket of the positioning link to the vehicle body, the filler hose can be protected from road surface protrusions such as stones by the mounting bracket or the positioning link while driving. be well protected.
