[Industrial applications]

 The present invention relates to an automobile synthetic resin fuel lid.

[0002]

[Prior art]

 BACKGROUND ART Electrodeposition coating methods and electrostatic coating methods are known as coating methods for automobile bodies. In this method, the vehicle body is charged to a constant potential, while the paint is charged to the opposite potential so that the paint is adsorbed on the vehicle body surface.

On the other hand, recently, a synthetic resin is often used as the fuel lid, but the synthetic resin fuel lid is not charged as it is, and there is a problem that only the fuel lid portion is not coated at the time of painting the vehicle body. In order to deal with this, it has been proposed to apply a conductive coating on the surface of the fuel lid main body, make it electrically conductive to the vehicle body, charge the vehicle body and the lid main body, and paint at the same time. (See Japanese Utility Model Laid-Open No. 3-69531).

【Example】

 1 and 2, reference numeral 1 is a vehicle body made of metal such as steel plate, and 2 is a fuel lid provided on the side surface of the vehicle body. As shown in FIG. 5, the fuel lid 2 has the same surface as the surface of the vehicle body 1 in the closed state, is opened at the time of refueling, the plug 3 attached inside is opened, and gasoline is injected.

The fuel lid 2 has a substantially disc-shaped lid body 4 made of a synthetic resin such as polybutylene terephthalate (PBT), and a hinge portion 5 in which carbon is mixed in PBT at about 5 to 20% to give conductivity. A metal hinge pin 6 that connects the lid body 4 and the hinge portion 5 and rotatably supports the lid body 4 is formed. The hinge portion 5 is fixed to the vehicle body 1 via the bolts 7, 7. The lid body 4 has an arm portion 8 connected to the hinge portion 5.

On the surface of the lid body 4, first, a conductive coating layer is formed by spraying a conductive primer, and then an intermediate coating layer is formed by electrodeposition coating. A surface layer is formed on the surface by electrostatic coating.

Two protrusions 9 and 9 are formed at the tip of the arm portion 8 of the lid body 4, and holes 10 1 and 10 2 are provided respectively. The hinge portion 5 is provided with other protrusions 11 and 11 having a positional relationship of contacting the insides of the protrusions 9 and 9, and holes 12 and 12 are provided therein. A hinge pin 6 made of a conductive metal such as SUS or iron is fitted into these holes 10, 10, 12, 12. Reference numeral 13 denotes a knurled portion engraved on the left side of the hinge pin 6 in the figure, and the knurled portion 13 supports the hinge pin 6 so as to bite into the arm portion 8. Therefore, the hinge pin 6 rotates as the lid body 4 rotates. Reference numeral 14 denotes a conductive coating layer deposited on the surface of the lid body 4, and the coating layer 14 also covers the lid body 4 including the arm portion 8 and a portion of the hinge pin 6 exposed to the outside from the protruding portion 9. Is formed.

In such a structure, the conductive coating layer 14 that covers the lid body 4 is electrically connected to the vehicle body 1 via the hinge pin 6 and the hinge portion 5. The electrical passage in the hinge pin 6 is ensured by the conductive coating layer 14 at both ends of the hinge pin 6 and the surface where the hinge pin 6 contacts the protrusions 11 and 11 in the holes 12 and 12.

FIG. 3 shows another embodiment, in which the lid body 4 is formed of PBT in which carbon is mixed and conductivity is imparted. The other structure is the same as the above-mentioned embodiment. Also in this structure, the electric passage is formed through the arm portion 8, the hinge pin 6, and the hinge portion 5 of the lid body 4.

FIG. 4 shows still another embodiment. Most of the lid body 4 is made of a synthetic resin such as PBT that does not have conductivity, and only one of the protrusions 9A of the arm 8 is made conductive. It is made of synthetic resin. Therefore, it is necessary to form the conductive coating layer 14 on the surface of the lid body 4 which has no conductivity. Further, in this embodiment, also in the hinge portion 5, the protrusion 11A corresponding to the protrusion 9A formed of the conductive synthetic resin is formed of the conductive synthetic resin. It is extended to the part that touches 1. It is not necessary to form a conductive coating layer on the non-conductive resin portion of the hinge portion 5. The lid body 4 and the hinge portion 5, which are composed of the conductive resin portion and the non-conductive resin portion, can be formed by a double injection molding method.

In this structure as well, the vehicle body 1 is attached to the vehicle body 1 through the protruding portion 9A of the lid body arm portion 8 formed of the conductive resin, the hinge pin 6 and the protruding portion 11A of the hinge portion 5 formed of the conductive resin. An electrical pathway is established for communication.

[0020]

[Effect of device]

 According to the present invention, since the hinge portion supporting the hinge pin is formed of the conductive synthetic resin, the lid body and the hinge portion formed of the conductive coating layer or the conductive synthetic resin adhered to the lid body. The contact area with is expanded and the electrical connection is ensured. Therefore, even if a potential is applied to the vehicle body, the lid body will surely be at the same potential as the vehicle body, and even if the lid body is made of synthetic resin, it will be integrated at the same time when the vehicle body is electrodeposited or electrostatically coated. Can be painted on.

As seen in the conventional hinge made of a metal plate, when the tip of the hinge fitting is bent in a circle to form a hinge pin insertion tube, the diameter of the insertion tube accompanying the lid opening / closing operation, which is expected, is increased. Accidents that cut off the electrical passage between the lid body and the vehicle body are prevented. That is, when such electrical cutoff occurs, static electricity is generated in the lid main body, which is discharged between itself and the vehicle body to generate a spark, which may ignite gasoline. Therefore, the lid body must always be electrically connected to the vehicle body. According to the present invention, even if the lid main body is repeatedly opened and closed, the electrical connection between the lid main body and the hinge portion is surely made, so that no discharge occurs.
