Description

[Detailed explanation of the idea] The present invention relates to an automobile fuel injection device.

Hitherto, a vehicle body pillar with a filler box is known (see Japanese Utility Model Publication No. 55-44669). In addition, as shown in FIGS. 5 and 6, an opening d is provided in the vehicle body pillar c located between the front door a and the rear door b of the automobile to form a filler box e, and the fuel passing through the vehicle body pillar c is There is a device in which the injection port g of the injection tube f projects into the filler box e and a lid h is attached to the opening d, but there is a problem in that it takes time and effort to form the opening d and the filler box e. Furthermore, if it is desired to reduce the width w of the portion of the vehicle body pillar c exposed to the outside of the vehicle for reasons of design, it is necessary to provide an edge portion i of a predetermined width w ₁ in order to form the opening d. Another problem was that it was difficult to narrow the exposure width w to a desired width.

The present invention, as a means to solve the above problems,
A stepped portion recessed inwardly across the vehicle body pillar in the width direction is formed in the outer member that forms the outer surface of the vehicle body pillar, and a through hole is provided in the bottom surface of the stepped portion, and fuel is injected into the through hole. The inlet portion is attached so as to protrude outward, the lowered step portion has a width substantially equal to the width of the outer surface of the vehicle body pillar, and a lid body covering the fuel inlet portion has an outer surface flush with the outer surface of the vehicle body pillar. An object of the present invention is to provide a fuel injection device for an automobile, which is characterized in that it is attached so as to be openable and closable.

In this fuel injection device, since the outer member of the vehicle body pillar itself constitutes a filler box by its stepped portion, an opening for forming a filler box is provided in this outer member, or a filler is inserted into this opening. There is no need to attach a member for forming a box. Further, the fact that the opening is not required means that there is no need to form an edge for the opening on the outer member, and the width of the vehicle body pillar exposed to the outside of the vehicle can be reduced accordingly. Further, since the width of the lid body is approximately equal to the width of the outer surface of the vehicle body pillar, it is possible to form an appearance without bordering by the vehicle body pillars on both sides of the lid body.

Embodiments of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a fuel injection device for a wagon-type automobile 2, in which a fuel injection pipe 3 is passed upward from the fuel tank into a closed-section vehicle body pillar 6 located between a front door 4 and a rear door 5, and is installed to inject fuel. The inlet part 7 is exposed to the outside of the vehicle from the vehicle body pillar 6, and a lid body 8 covering the fuel inlet part 7 is attached to the vehicle body pillar 6 so as to be openable and closable.

The vehicle body pillar 6 includes a flat inner member 11 and an outer member 12 having a convex cross section with a narrow outer surface 13 joined at respective flange portions 14 and 15, forming the outer surface 13 of the vehicle body pillar 6. A step-down part 16 is formed in the outer member 12 that is recessed one step inward across the vehicle body pillar 6 in the width direction.
A through hole 18 is formed in the bottom surface 17 of the housing.

The fuel injection pipe 3 has a bent upper end so that the fuel injection port 7 protrudes from the through hole 18 into the lowered part 16, and a bracket 21 is fixed to the upper end. It is fixed to the back surface of the lowered part 16 via. Lowering part 16
On the bottom surface 17 of the vehicle, a hinge bracket 23 is fixed to the end on the front door side, and a lock piece 24 is fixed to the end on the rear door side. One end of the lid 8 is pivotally supported by a pin 25 so that the outer surface of the lid when closed is flush with the outer surface 13 of the vehicle pillar. Note that a key cylinder 2 is attached to the other end of the lid 8.
6 is provided, and an engagement piece 27 that engages with the lock piece 24 is attached to the key cylinder 26. In the figure, 28 is a cap of the fuel injection pipe 3.

When injecting fuel, insert the key into the key cylinder 26, disengage the engagement piece 27 and lock piece 24, open the lid 8, remove the cap 28, and insert the fuel injection gun 29 into the fuel injection pipe 3. Inject fuel.

Incidentally, in the above embodiment, the bottom surface 17 of the step-down portion 16
Although the bottom surface is vertical, the bottom surface may be inclined so that the fuel inlet portion 7 projects obliquely upward.

In the above embodiment, the vehicle body pillar between the front door and the rear door has been described, but other vehicle body pillars, such as a rear pillar at the rear of the vehicle body, may be used.

As described above, according to the present invention, by providing the outer member forming the outer surface of the vehicle body pillar with a step-down portion that crosses the vehicle body pillar in the width direction, the formation of the conventional filler box is no longer necessary, and the structure is simplified. This makes it easier to manufacture, lowering production costs, and since there is no need to provide an opening for forming the filler box in the vehicle body pillar, the width of the vehicle body pillar exposed to the outside of the vehicle can be narrowed, and the width of the lid body can be reduced. Since it is made substantially equal to the width of the outer surface of the vehicle body pillar, an excellent effect can be obtained in that it is possible to eliminate the edging by the vehicle body pillars on both sides of the lid body and improve the appearance of the vehicle body.
