Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fuel flap stopper structure that is openably and closably attached to a fuel inlet of a vehicle body.

[0002]

[Prior art]

 As shown in FIG. 2, generally, a fuel inlet of a vehicle is a fuel saucer c mounted inside an opening b provided in a vehicle body outer plate a, and a fuel for opening and closing the opening of the vehicle body outer plate. The fuel pipe e consists of a flap d and the fuel pipe e penetrates through the central portion of the fuel saucer c and its tip projects into the fuel saucer c. The fuel flap d is opened and the cap of the tip of the fuel pipe e is opened. Remove the fuel pipe by inserting a fuel injection gun into the fuel pipe to inject the fuel, and when the fuel injection is completed, screw the cap into the fuel pipe e and close the fuel flap d to inject fuel into the fuel tank. Is designed to do.

The fuel flap d is rotatably attached to the fuel saucer c by a hinge arm, and holds the fuel flap d in a closed state flush with the vehicle body outer plate a without rattling. In addition, it is necessary to provide a stopper made of an elastic material that elastically contacts the back surface of the fuel flap d in the closed state (see, for example, Japanese Utility Model Laid-Open No. 62-167730).

[0004]

[Problems to be solved by the device]

 The fuel flap stopper is conventionally configured as an independent dedicated component, and the stopper, which is the dedicated component, is assembled and fixed to the fuel saucer, which is disadvantageous in terms of the number of components and cost. Not only that, if there is a problem with the stopper assembly accuracy, there is a risk of rattling of the fuel flaps and leakage of water in the closed state, so the task of assembling the stopper is difficult. There is.

The present invention aims to solve the above conventional problems.

[0006]

[Means for Solving the Problems]

 The present invention is a fuel saucer in which a packing part made of, for example, vinyl chloride is integrally formed in a fuel pipe through hole of a synthetic resin soda body by double molding, and the projecting part is protruded from a surface of a flange part of the sosa body by a predetermined height. In a fully closed state of the fuel flap, the stopper portion elastically contacting the back surface of the fuel flap is made of the same synthetic resin as the packing portion by double molding together with the packing portion. Is.

[0007]

[Action]

 As described above, the stopper part is formed by double molding together with the packing part and is integrated with the fuel saucer, compared to the conventional structure in which the stopper, which is an independent dedicated part, is assembled and fixed to the fuel saucer. The cost can be reduced and the man-hours for assembly can be reduced, and the accuracy of the stopper is improved so that there is no risk of rattling of the fuel flap or water leakage, and the quality of the fuel injection port can be improved. You can

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

In FIG. 1, reference numeral 1 is a fuel saucer, and the fuel saucer 1 comprises a saucer body 2, a packing portion 3, and a stopper portion 4.

The saucer body 2 is a dish-shaped relatively hard synthetic resin material composed of a bottom surface portion 21, a rising surface 22 rising from the outer periphery of the bottom surface portion 21 and a flange portion 23 at the edge of the rising surface 22. For example, it is integrally formed of polypropylene containing glass fiber.

A through hole 21 a through which the tip of the fuel pipe 7 penetrates is provided in the bottom surface portion 21 of the sorcer body 2, and the peripheral edge of the through hole 21 a and the outer peripheral surface of the fuel pipe 7. A packing part 3 made of a relatively soft synthetic resin material, for example, vinyl chloride, which fills the gap between the two, is integrally formed by double-molding the saucer body 2.

The flange portion 23 of the saucer body 2 is provided with packing mounting holes 23a at a plurality of places (usually two places), and a synthetic resin material (for example, vinyl chloride) of the same quality as the packing portion 3 is provided. The stopper portion 4 that is connected from the packing portion 3 through the back side of the saucer body 2 and penetrates the hole 23a from the back surface side of the flange portion 23 and projects to the front surface side of the flange portion 23 by a predetermined height. At the same time as the double molding of 3 is formed integrally with the packing part 3. Reference numeral 5 is a continuous portion which is joined to the back surface side of the saucer body 2 to integrally connect the packing portion 3 and the stopper portion 4.

As described above, the fuel saucer 1, which is configured by integrally forming the packing portion 3 and the plurality of stopper portions 4 on the saucer main body 2 by double molding, includes the flange portion 23 of the saucer main body 2. By being joined to the peripheral bracket 6 fixed to the peripheral edge flange 9a of the opening of the vehicle body outer plate 9 and fixed by means such as screwing, it is mounted inside the opening of the vehicle body outer plate 9 and A recessed portion serving as a fuel inlet is formed in the plate portion. Then, in a state in which the fuel flap 8 which is rotatably attached to the fuel sorcer 1 via a hinge arm (not shown) and which opens and closes the opening of the vehicle body skin 9 is closed and locked, the fuel is removed. The back surface of the flap 8 is elastically contacted with the stopper portion 4 formed integrally with the fuel sorcer 1 and is kept in the fully closed state where it is flush with the outer panel 9 of the vehicle body without rattling.

In the above, the one in which the packing part made of, for example, vinyl chloride is double-molded on the saucer main body made of polypropylene containing glass fiber to form an integrated fuel saucer has been conventionally used. Since the stopper part is formed at the same time when the parts are double-molded, the cost is almost the same as the conventional one in which only the packing part is double-molded, and the stopper, which is an independent dedicated part, is attached to the fuel saucer. Compared to the conventional fixed structure, the cost and the number of assembling steps can be reduced, and the accuracy of the stopper is improved, and there is no risk of rattling of the fuel flap or water leakage, and quality is improved. Can be measured.

[Effect of device]

 As described above, according to the present invention, it is possible to reduce the cost of the fuel saucer assembly and the assembly man-hours with an extremely simple structure, and also to improve the quality of the fuel inlet portion. However, it can bring great effects in practical use.
