DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fuel tank mounting structure for an automobile.

[0002]

2. Description of the Related Art FIG. 7 shows a conventional structure. Reference numeral 1 denotes a rear floor panel. A fuel tank 2 is mounted on a lower surface of the rear floor panel 1 with a pair of clamp belts 3 tightening the fuel tank in the longitudinal direction of the vehicle body. It is. The clamp belt 3 has brackets 4 at both ends thereof, and these brackets 4 are fixed to bolts and nuts 6 on cross members 5 of a floor frame member which are joined and arranged on the lower surface of the rear floor panel 1 in the vehicle width direction. In the figure, 7 indicates a rear seat, and 8 indicates a spare tire. This similar structure is described, for example, in Japanese Utility Model Application Laid-Open No. 61-87728.
And Japanese Utility Model Application Laid-Open No. 61-159218.

[0003]

As shown in FIG. 8, depending on the type of vehicle, a floor functional component, for example, a suspension member 8 extends in the vehicle width direction just below the rear floor panel 1 at a portion where the fuel tank 2 is mounted. , May be arranged.
In this case, in order to avoid interference with the suspension member 8 and to dispose the clamp belt 3 in close contact with the tank bottom, the fuel tank 2 needs to be formed so that the tank bottom is entirely slanted and flat. Therefore, the tank volume is inevitably reduced.

[0004] Therefore, the present invention can minimize the decrease in the tank volume, and can tightly arrange the clamp belt on the bottom surface of the tank, so that the fuel tank can be properly mounted on the lower surface of the rear floor panel. An object of the present invention is to provide a mounting structure for a fuel tank for a vehicle to which the fuel tank can be mounted.

In the fuel tank mounting structure, one side wall of the fuel tank
An insertion hole of the belt member is formed through the other side wall, and mounting the fuel tank on the vehicle by inserting the belt member into the insertion hole. More preferably, on one side wall of the fuel tank
Receives floor functional parts located below the rear floor panel.
Forming a concave portion to accommodate therein and forming the insertion hole in the concave portion.
The belt member pushes the other side wall of the fuel tank to the vehicle body.
A clamp belt for tightening and tightening the fuel tank;
One is inserted into the insertion hole and one is on the other side of the fuel tank
The other is connected to the clamp belt by the fuel tank.
And a belt suspension tool to be pulled toward the concave side of the link.

[0006]

According to the present invention, the fuel tank is mounted on the vehicle by inserting the belt member into the insertion hole of the belt member which penetrates one side wall and the other side wall of the fuel tank. the fuel tank can be a properly mounted to Turkey without reducing the volume. Further, by fixing both ends to the lower surface of the rear floor panel while the clamp belt is supported by the belt suspending device, the intermediate portion of the clamp belt is pulled and suspended by the belt suspending device so that the concave portion at the bottom of the fuel tank is formed. Surface, so that the clamp belt no longer lifts from the bottom of the fuel tank,
The fuel tank can be properly mounted.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings, in which the same reference numerals are given to the same parts as in the above-mentioned conventional construction.

In FIGS. 1 and 2, a fuel tank 2 is disposed on the lower surface of a rear floor panel 1, and the fuel tank 2 is fixed to a cross member 5 by bolts and nuts with a clamp belt 3 having brackets 4 at both ends. 6. The basic structure of fixing and mounting in the front-rear direction of the vehicle body is the same as that of the related art.

Here, the fuel tank 2 is formed of, for example, a resin material, and a floor functional component such as a suspension member 8 extending in the vehicle width direction below the rear floor panel 1 is provided at the bottom thereof. Receiving recess 10
Are formed stepwise, and the corners of the recess 10 (fuel tank) are formed.
Tank 2 ) and the tank upper wall (other side of fuel tank 2 )
), And a belt insertion hole 11 is formed integrally therewith . When a clamp belt is disposed near the side of the fuel tank 2, the belt insertion hole may be a mounting hole 11 ′ as shown in an enlarged view of a main part of FIG. .

Then, the intermediate portion of the clamp belt 3 is inserted into the belt insertion hole 11 by a belt suspender 12.
The intermediate portion of the clamp belt 3 is disposed in close contact with the surface of the concave portion 10 by being pulled and hung on the lower surface of the rear floor panel 1. That is, the belt suspender 12 and the clamp bell
And the fuel tank is inserted through the belt insertion hole 11
2 is mounted on the vehicle.

The belt suspender 12 has a locking ring 1 at both ends.
Includes a 4, 15, belts were engaged with one of the locking ring 14 to the rear floor panel 1 bracket 16 joined to the lower surface
The clamp belt 3 is inserted through the locking ring 15 at the other end, and an intermediate portion of the clamp belt 3 is suspended. The lower locking ring 15 through which the clamp belt 3 is inserted is of a one-side open type so that the clamp belt 3 can be easily inserted, and the open end 15 a is closed by a stopper ring 17.

The belt suspender 12 may be formed of a ring-shaped steel wire 18 having an open end 18a closed by a stopper ring 17 on the lower side as shown in FIG.

As shown in FIG. 5 or FIG. 6, a protruding edge 19 is formed on the inner periphery of the belt insertion hole 11 so that the belt suspending tool 12 can be formed on the peripheral wall of the belt insertion hole 11 by the protruding edge 19. It is preferable to prevent the fuel tank 2 from being damaged due to interference. The protruding edge portion 19 can effectively use burrs generated when the fuel tank 2 is formed.

According to the structure of the above embodiment, the fuel tank 2
Belt insertion hole 11 penetrating through one side wall and the other side wall
The belt insertion hole 11 has a belt suspender for a belt member.
12 and the fuel tank 2 was mounted on the vehicle,
Irrespective of the shape of the fuel tank 2, the volume is unnecessarily reduced.
Mount the fuel tank 2 properly on the vehicle without reducing
Rukoto can. In addition, since the fuel tank 2 is formed with a concave portion 10 for receiving the suspension member 8 at the bottom thereof in a stepped manner so as to avoid interference with the suspension member 8 , the fuel tank 2 is formed as compared with the case where the tank bottom is entirely inclined. Thus, a decrease in volume can be suppressed. Even if the concave portion 10 is present in the tank bottom as described above, the intermediate portion of the clamp belt 3 is inserted into the belt insertion hole 11 formed in the fuel tank 2 at the concave portion 10 so that the belt suspending tool is disposed. 12, the intermediate portion of the clamp belt 3 is recessed 10
As a result, the clamp belt 3 does not rise from the tank bottom surface, and the fuel tank 2 can be properly mounted.

[0015]

According to the present invention as described above, according to the present invention, through the one side wall and the other side wall of the fuel tank to form an insertion hole of the belt member, the fuel and inserting the belt member into the insertion hole Since the tank is mounted on the vehicle, the fuel tank can be properly mounted on the vehicle irrespective of the shape of the fuel tank and without unnecessarily reducing the volume.
