Description

[Detailed description of the invention] The present invention relates to an improvement in the structure of a fuel injection part for a vehicle.

Generally, in front wheel drive vehicles (hereinafter referred to as FF vehicles), as shown in FIG.
A fuel injection part At arranged at the bottom of the floor and into this fuel tank 1
There is one that can be placed on the front side of the rear fender 3.
There is a structure in which the length of the filler tube 7A is shortened to reduce costs and weight.

In this type of type, the conventional structure of the fuel injection part is as shown in FIGS. 1 and 2. As shown in FIGS. A filler paste 5 is installed by spot welding, and the filler tube 7 is opened approximately in the center of the filler base 5.
The mouth cover 8 attached to the tip of A is fixed to the edge of the mounting hole 6 with screws 9, while a filler lid 10t'' hinge 11 is provided on the front edge of the filler paste 50 to open and close the opening 4.
There are some that are rotatably mounted through the. In addition, 15
is a hook 2-cap attached to the mouth cover 8.

By the way, in such a conventional fuel injection part structure, when injecting fuel, the above-mentioned filler lid 10 is opened and a fuel injection gun (not shown) is inserted into the tip opening of the filler tube 7A. However, the center axis P of the tip of the filler tube 7A extends in the vehicle width direction, and the tip opening of the filler tube 7A is aligned with the rear fender panel 6a.
In order to avoid interference between the fuel injection gun and the filler lid 10,
The opening angle θ of the filler lid 10 is set to a certain degree, for example, 120°.
I had to make it fairly thick. Therefore, in order to increase the opening degree 0 of the filler lid 10 to a certain extent, the rotary shaft side end of the filler lid 10 and the end panel 6
A large gap Jt between the opening 4 edges of the filler tube 7A must be ensured, and the quality of the appearance when the lid 10 is closed is impaired accordingly.
When connecting the filler tube 7A to the side of the fuel tank 1, the fuel tank 1 and the fuel injection part are offset in the longitudinal direction of the vehicle body, and the tip axis P of the filler tube 7A is Since the filler tube 7A extends in the vehicle width direction, it is necessary to bend the filler tube 7A at a substantially right angle at at least two positions. The longitudinal dimension becomes large, and the fuel injection part-A position is separated from the fuel tank 1 position. For this reason, the filler tube 7 becomes long, and there is a limit to the demands for cost reduction and weight reduction.

The present invention has been made based on the above-mentioned viewpoints, and its objects are to narrow the gap between the fuel injector and the opening edge of the outer panel of the vehicle body, thereby improving the appearance quality, and to improve the appearance quality of the filler tube. By reducing the longitudinal dimension of the ψ body, we are developing a vehicle fuel injection part structure that can reduce costs and weight.

The gist of the present invention resides in a vehicle fuel injection part structure in which the tip of the filler tube is arranged such that the center axis of the filler tube is inclined rearward with respect to the vehicle width direction.

Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.

In the embodiment shown in FIG. 3, the basic configuration of the fuel injection part is to attach a filler paste 5 by spot welding to the edge of the opening 4 made in the rear channel 3a, and to insert a filler tube into the deep hole 6 of the filler paste 5. The tip of the filler paste 7 is inserted and locked through the opening cup (-8), and the filler lid 10t is attached to the front edge of the filler paste 5 through the hinge 11.

In this embodiment, the mounting surface of the filler tube 7 of the filler pace 5 is an inclined surface 12 that is inclined inward with respect to the front and rear sections of the vehicle body. ' is tilted backward at an angle f, for example, about 25° to 35° with respect to the vehicle width direction,
It is held in filler paste 5.

Further, as shown in FIG. It is formed in such a shape that it has a substantially right-angled curved portion 13t toward the fuel injection portion, and an obtuse-angled curved portion 14 toward the fuel injection portion, and passes through the rear floor panel, rear inside panel, etc. (none of which are shown). It is arranged as follows.

Therefore, according to the vehicle fuel injection part structure according to this embodiment, at the time of fuel injection, as shown in FIG. (not shown) is recommended.
At this time, since the tip of the filler tube 7 is inclined backward from the direction of the vehicle, the fuel injection gun must also be inserted in the direction along the central axis P' direction of the filler tube 7, and the filler lid 10 Even if the opening angle θ' is reduced to approximately 90°, the filler lid 10 and the fuel injection gun will not interfere with each other, and a sufficient working space for the fuel injection gun can be secured. In this state, since the opening angle 0' of the filler lid 10 can be made small, it is possible to make the gap 1' between the edge of the filler lid 10 on the rotating shaft side and the 4 edges of the opening of the rear 7 ender panel 3a small. C,
When the filler lid 10 is closed, the gap L' becomes almost inconspicuous, and the appearance quality at the periphery of the filler lid 10 is improved accordingly. Further, as shown in FIG. 4 (C1), the filler tube 7 has curved portions 13 and 14 at the two points, and one of the curved portions 14 is bent at an obtuse angle. The radius of curvature of the curved portion 14 is increased, and accordingly, the dimension L' of the filler tube 7 in the longitudinal direction of the vehicle body can be made shorter than L shown in FIG. 4B). Therefore, the position of the fuel injection part A does not have to be closer to the position of the fuel tank 1 than in the past, and the filler tube 7 can be shortened, thereby reducing cost and weight.

In the above embodiment, the present invention is applied to a type in which 1 ton of fuel tank is placed under the floor of the rear seat, but the present invention is not necessarily limited to this, and the fuel tank is placed under the floor of a trunk room or the like or in a trunk room. fuel tank 1
It goes without saying that the present invention can be applied to the 't-arranged type.

Also, the design of the attachment of the filler tube 7 to the filler base 5 may be changed as appropriate.

As explained above, according to the fuel injection part structure for a vehicle according to the present invention, the tip of the filler tube is arranged so that the center axis of the filler tube is tilted rearward with respect to the vehicle width direction. The insertion direction of the fuel injection gun is also tilted backwards relative to the vehicle width direction, and even if the opening angle of the filler lid is made small, there is no interference between the filler lid and the fuel injection gun.
Not only can you secure a larger fuel injection space, but because the opening angle of the filler lid is smaller, the gap between the edge of the filler lint on the rotating shaft side and the opening edge of the vehicle body exterior plate can be narrowed, improving the appearance quality of the filler lid periphery. can be improved. Also, since the Iu axis at the tip of the filler tube is tilted backwards in the vehicle width direction, when arranging the filler tube, the radius of curvature of the curved part of the filler tube near the fuel injection part should be made small. You can do that,
It is possible to make the dimension of the filler tube in the longitudinal direction of the vehicle body shorter than in the past, and it is possible to provide an inexpensive and lightweight fuel injection port structure.
