JP-A-8-142694

  In view of the above facts, the present invention provides a fuel tank fueling part structure that can facilitate fueling by stably supporting the fueling gun with the fueling gun inserted into the fueling port. Let it be an issue.

  In the first aspect of the present invention, a fuel filler member constituting a fuel filler port into which a fuel gun for fueling a fuel tank is inserted, an on-off valve capable of opening and closing the fuel filler opening, and a lower part of the on-off valve are provided. And is opened and closed so that it can be rotated between an open position where the upper part of the on-off valve moves to the fuel tank side and is opened by the fuel gun, and the closed position which closes the fuel inlet. A rotation member for attaching a valve to the fuel filler member, and the opening / closing valve or the pivot member, and supports the fuel gun inserted into the fuel filler port when the opening / closing valve is in the open position. And a support member.

  In this fuel tank fueling part structure, the on-off valve is pivotally attached to the fuel filler member below by a pivoting member. The fuel filler port is normally closed by an on-off valve at the closed position, but when the fuel gun is inserted into the fuel filler port, the on-off valve is pressed by the fuel gun to the open position. In the open position, the upper part of the on-off valve has moved to the fuel tank side, and the fuel filler opening is opened.

  A support member is provided on the on-off valve or the rotation member. When the on-off valve is in the open position, the fuel gun inserted into the fuel filler port is supported by the support member. Thereby, since the fueling gun is stably supported, it becomes easy to perform fueling.

  According to a second aspect of the present invention, in the first aspect of the present invention, the support member supports the fuel gun outside the fuel filler member.

  Since the support member supports the fuel gun outside the fuel filler member, the fuel supplier can visually recognize the state in which the fuel gun is supported by the support member, thereby facilitating fueling.

  According to a third aspect of the present invention, in the second aspect of the present invention, the rotating member is provided on the support member outside the fuel filler member.

  That is, the support member supports the fuel gun on the outside of the fuel filler member, and the rotating member is also provided on the support member on the outer side of the fuel filler member. Since the position where the support member supports the fuel gun is close to the position of the rotating member, the load of the fuel gun supported by the support member can be applied to the rotating member to stably support the fuel gun. become.

  According to a fourth aspect of the present invention, in the third aspect of the present invention, the support member is provided between the rotating member and the on-off valve, and the fuel gun is disposed on the opposite side of the rotating member. It has a support plate provided with a support portion to support, and the support plate supports the oil supply port by the support portion in a posture along the outer surface where the oil supply port of the oil supply port member is provided.

  That is, the support member is provided between the rotating member and the on-off valve and has a support plate. The support plate supports the fuel gun by the support portion on the opposite side of the rotating member in a posture along the outer surface provided with the fuel filler opening. The load of the lubrication gun acts directly on the rotating member, and an inadvertent rotational moment or bending force does not act on the support plate, so the lubrication gun is supported more stably and the durability of the support plate is increased. Is possible.

  Since the present invention has the above-described configuration, it is possible to facilitate refueling by stably supporting the refueling gun while the refueling gun is inserted into the refueling port.

It is a perspective view which shows the fueling part structure of the fuel tank of 1st Embodiment of this invention from the outer side of a fueling port member. It is sectional drawing which shows the fueling part structure of the fuel tank of 1st Embodiment of this invention in the state by which the fueling gun was inserted. FIG. 3 is an arrow diagram in the direction of arrow A in FIG. 2 showing the fuel supply structure of the fuel tank according to the first embodiment of the present invention with a fuel gun inserted. It is sectional drawing which shows the fueling part structure of the fuel tank of 2nd Embodiment of this invention in the state by which the fueling gun was inserted.

  FIG. 1 shows the external shape of a fuel tank fueling part structure (hereinafter simply referred to as “fueling part structure”) 12 of a fuel tank according to a first embodiment of the present invention. As can be seen from FIG. 1, in the present embodiment, a cap for closing the fuel filler opening is unnecessary, and a so-called capless structure is formed.

  A fuel tank (not shown) is connected to the lower end of an inlet pipe for refueling, and an oil supply section structure 12 is applied to the upper part of the inlet pipe.

  A substantially cylindrical oil filler member 16 is formed at the top of the inlet pipe. The inside of the fuel filler member 16 serves as a fuel filler 26, and a fuel gun 28 can be inserted into the fuel filler 26 from the opening 18 at the upper end to supply fuel to the fuel tank.

  A flapper valve 20 is arranged at the upper portion of the fuel filler member 16, that is, at the opening 18 of the fuel filler port 26. The flapper valve 20 has a valve main body 24 having a shape capable of closing the opening 18 (in the present embodiment, a disc shape). Below the valve body 24, a hinge 22 constituting a rotating member of the present invention is provided.

  As shown in FIG. 2, at the lower part of the inner surface of the fuel filler member 16, the valve body 24 supports the valve body 24 from below with the opening 18 open, and limits the rotation range of the valve body 24. A stopper projection 32 is formed. As a result, the valve body 24 is brought into contact with the peripheral portion of the opening 18 of the fuel filler member 16 at a predetermined rotation angle, more specifically, as shown by a two-dot chain line in FIG. As shown by the solid line, the hinge position is such that the valve main body 24 opens the opening 18 and can rotate between the opening position HP that contacts the stopper projection 32 as shown by the solid line. 22 is attached to the fuel filler member 16.

  Around the valve body 24, a seal member 24S formed in an annular shape by an elastic member is provided. When the valve main body 24 is in the closed position TP, the seal member 24S comes into contact with the mouth edge of the opening 18 so that the closed state of the opening 18 by the valve main body 24 can be reliably maintained. .

  From the lower part of the valve body 24, a connecting piece 34 that extends toward the outside of the opening 18 and curves downward is extended with the valve body 24 closing the opening 18. The curved shape of the connecting piece 34 is an arc shape centered on the hinge 22. A support plate 36 is provided between the tip of the connecting piece 34 and the hinge 22. That is, as can be seen from FIG. 3, the hinge 22 is provided below the support plate 36. The position of the hinge 22 is always located outside the fuel filler member 16 regardless of the posture of the valve body 24. The upper part of the support plate 36 protrudes further upward than the connecting piece 34, and the upper end is a support part 36 </ b> S for supporting the fuel gun 28. The support plate 36 (support portion 36 </ b> S) is also always outside the fuel filler member 16 regardless of the posture of the valve body 24. In the first embodiment, the connecting piece 34 and the support plate 36 constitute the support member of the present invention.

  The angle formed by the valve main body 24 and the support plate 36 coincides with the rotation angle of the valve main body 24 from the open position HP to the closed position TP. When the valve body 24 is in the open position HP, the support plate 36 is parallel to the outer surface 16S (the surface in which the fuel filler port 26 is opened) of the fuel filler member 16.

  A flapper valve spring 38 is attached to the hinge 22. The flap valve spring 38 urges the valve body 24 toward the closing position TP via the support plate 36 and the connecting piece 34, so that the oil supply port 26 is not inadvertently opened. The biasing force of the flapper valve spring 38 is set smaller than the pressing force acting from the fuel gun 28. Therefore, when the flapper valve 20 is pushed by the fuel gun 28 inserted from the opening 18, the flapper valve 20 moves (rotates) to the open position HP against the urging force of the flapper valve spring 38.

  A guide projection 40 is formed at the upper portion of the inner surface of the filler port member 16, at a position facing the stopper projection 32 in FIG. The guide protrusion 40 comes into contact with the fuel gun 28 from above while the fuel gun 28 is being inserted into the fuel inlet 26 and guides the insertion of the fuel gun 28. Thereby, the careless movement of the fuel gun 28 upward is restricted.

  A rib 30 that faces the guide protrusion 40 protrudes from the upper portion of the valve body 24 when the valve body 24 is in the open position. The rib 30 comes into contact with the fuel gun 28 from below during the insertion of the fuel gun 28 into the fuel filler 26 and guides the insertion of the fuel gun 28. As a result, the inadvertent downward movement of the fuel gun 28 is restricted.

  Next, the effect | action of the oil supply part structure 12 of this embodiment is demonstrated.

  Normally, as indicated by a two-dot chain line in FIG. 2, the flapper valve 20 is maintained at the closed position TP under the biasing force of the flapper valve spring, and the fuel filler 26 (opening 18) is closed. Yes.

  When refueling, the refueling gun 28 is inserted into the refueling port 26. The biasing force of the flapper valve spring is set to be smaller than the pressing force acting from the fuel gun 28, and the flapper valve 20 pushed by the fuel gun 28 rotates to the open position HP. Thereby, the fueling gun 28 can be further inserted into the interior to perform fueling.

  Thus, from the middle of inserting the fueling gun 28 into the fueling port 26, the fueling gun 28 is inadvertently moved downward and upward by the rib 30 of the valve body 24 and the guide protrusion 40 of the fueling port member 16. It is regulated and the insertability of the fuel gun 28 is improved.

  As shown by a solid line in FIG. 2, the support plate 36 is substantially parallel to the outer surface 16 </ b> S of the fuel filler member 16 in a state where the valve body 24 has moved to the open position HP. And the support part 36S of the state of the support plate 36 is contacting and supporting the fuel supply gun 28 from the downward direction. As a result, the oil supply gun 28 can be stably supported from below by the support plate 36 during and after the oil supply gun 28 is inserted into the oil supply port 26, thereby facilitating refueling. In addition, since the fuel supply gun 28 is supported by the support plate 36, the fuel supply gun 28 does not come into contact with the lip of the opening 18 or the seal member 24S of the valve body 24, so that damage to these members can be suppressed. .

  Particularly in the present embodiment, the support plate 36 (support portion 36 </ b> S) supports the fuel gun 28 outside the fuel filler member 16. For this reason, compared with the structure in which the support portion 36S supports the fuel gun 28 inside the fuel filler member 16, the oiler can visually check the support state of the fuel gun 28 by the support portion 36S. It becomes easier to refuel.

  As can be seen from FIG. 2, in the present embodiment, when the valve body 24 is in the open position HP, the support plate 36 is along the outer surface 16S of the fuel filler member 16, and the support portion 36S to the hinge 22 are illustrated. The cross section shown in FIG. 2 is linearly connected, and the position of the support portion 36 </ b> S is close to the hinge 22. For this reason, it is possible to stably support the oil supply gun 28 by causing the load of the oil supply gun 28 to act directly on the hinge 22.

  FIG. 4 shows a cross section similar to FIG. 2 of an oil supply portion structure 112 according to the second embodiment of the present invention. In the oil supply part structure 112 of 2nd Embodiment, the same code | symbol is attached | subjected about the component, member, etc. which are the same as the oil supply part structure 12 of 1st Embodiment, and detailed description is abbreviate | omitted.

  In the fuel filler structure 112 of the second embodiment, the hinge 114 is provided in the lower part of the valve body 24, that is, inside the fuel filler member 16. Further, a curved support piece 116 extends from the valve main body 24. When the valve main body 24 is in the open position, the support piece 116S has an end support portion 116S on the outside of the fuel filler member 16. The fuel gun 28 is supported. In the second embodiment, the support member 116 constitutes the support member of the present invention.

  In the oil supply portion structure 112 of the second embodiment configured as described above, the distance from the support portion 116S to the hinge 114 is longer than that of the oil supply portion structure 12 of the first embodiment. That is, in the oil supply portion structure 12 of the first embodiment of the present invention, the distance from the support portion 36S to the hinge 22 is shorter than the oil supply portion structure 12 of the second embodiment, so the oil supply gun 28 is held more stably. can do.

  Further, in the oil supply portion structure 112 of the second embodiment, the support portion 116S to the hinge 114 are connected by the curved support piece 116 and a part of the valve body 24, and the load from the support portion 116S to the hinge 114 is connected. The transmission path is not linear.

  In the oil supply portion structure 12 of the first embodiment, the load transmission path from the support portion 36S to the hinge 22 is linear, and the load of the oil supply gun 28 received by the support portion 36S directly acts on the hinge 22. For this reason, an inadvertent rotational moment or bending force does not act on the support plate 36. Thereby, the fuel supply gun 28 can be supported more stably.

  In particular, in the first embodiment, the support plate 36 extends along the outer surface 16S of the fuel filler member 16 in a state where the fuel gun 28 is supported by the support portion 36S. Thereby, rotation and bending of the support plate 36 can be suppressed more effectively.

  On the other hand, in the oil filler structure 112 of the second embodiment, the protruding length from the fuel filler member 16 (outer surface 16S) when the valve body 24 is in the closed position TP is the length of the support plate 36 in the first embodiment. It becomes shorter than the protruding length.

  In the above description, the fuel gun 28 inserted into the fuel filler port 26 is supported by the support plate 36 having the hinge 22 at the lower portion. In other words, the fuel supply gun 28 is supported by the support plate 36 provided on the hinge 22 (rotating member). For example, the valve main body 24 (open / close valve) supports the fuel supply gun 28. A member may be provided. More specifically, the fuel gun 28 is supported by a part of the connecting piece 34, and the support plate 36 is a member that transmits the load of the fuel gun 28 received by the connecting piece 34 to the hinge 22 (rotating member). The structure which acts as may be sufficient.
