Description

  The present invention relates to a fuel tank fueling portion structure.

  It is preferable that the fuel adhering to the surface of the fuel gun is not leaked to the outside when the fuel tank of an automobile or the like is supplied, especially when the fuel gun is removed from the fuel supply port. In Patent Document 1, in a state where the tube tip of the nozzle pipe of the liquid supply nozzle is inserted into the liquid supply port, gas is injected into the nozzle pipe and residual oil liquid adhering to the inside is discharged into the liquid supply port. Thus, there is described a liquid supply apparatus that prevents liquid dripping from the tip of the nozzle pipe after completion of the liquid supply operation.

  However, in the structure of Patent Document 1, only the oil liquid in the nozzle pipe is removed, and the fuel adhering to the surface cannot be removed.

JP 2009-292478 A

  In view of the above facts, the present invention has an object to obtain a fuel tank fueling part structure capable of wiping off the fuel on the surface of the fueling gun when the fueling gun is removed from the fueling port.

  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, and the fuel filler member are provided inside the fuel filler member, and the fuel gun is provided from the fuel filler port. And a wiping member that contacts the fuel gun and wipes off the fuel on the surface of the fuel gun when pulled out.

  In this fuel tank fueling part structure, when the fueling gun is pulled out from the fueling port, the wiping member provided inside the fueling port member comes into contact with the surface of the fueling gun and wipes the fuel on the surface of the fueling gun. To remove. Therefore, the amount of fuel adhering to the surface of the fuel gun is reduced as compared with a configuration in which such a wiping member is not provided. So-called dripping of the fuel adhering to the surface of the fuel gun can be suppressed.

  According to a second aspect of the present invention, in the first aspect of the present invention, an on-off valve capable of opening and closing the fuel filler opening is provided, and the wiping member is disposed on the deeper side of the fuel filler opening than the on-off valve. Yes.

  Therefore, the fuel tank can be refueled by opening the on-off valve to open the refueling port and inserting the refueling gun into the refueling port of the refueling port member. Since the wiping member is disposed on the deeper side of the fuel filler opening than the on-off valve, it is possible to suppress the fuel adhering to the surface of the fuel gun from being transferred (reattached) to the on-off valve.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, the fuel is supplied to the wiping member so that the fuel wiped off from the fuel supply gun does not reattach to the fuel supply gun. An escape portion is formed at a position spaced from the surface.

  Since the fuel wiped off from the fuel gun by the wiping member is released by the escape portion to a position separated from the surface of the fuel gun, the fuel can be effectively removed from the surface of the fuel gun.

  In invention of Claim 4, in the invention of any one of Claims 1-3, the said wiping member is being fixed to the said fuel filler member.

  By fixing the wiping member to the fuel filler member in this way, the contact state of the fuel filler member with the fuel gun can be satisfactorily maintained with a simple structure.

  According to a fifth aspect of the present invention, there is provided a fuel gun according to any one of the first to third aspects, wherein the fuel gun is provided on the fuel filler member and the wiping member is inserted into the fuel filler port. A pressing support member that supports the outer peripheral surface in a pressable manner;

  Thus, even when the fuel gun moves in the axial direction by pressing the wiping member against the fuel gun by the pressing support member, the contact state of the wipe member with respect to the fuel gun follows this movement. Can be maintained well.

  Since the present invention is configured as described above, the fuel on the surface of the fuel gun can be wiped off when the fuel gun is removed from the fuel filler port.

It is sectional drawing which shows the fueling part structure of the fuel tank of 3rd Embodiment of this invention in the state by which the fueling gun was inserted.

  1 and 2 show 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.

  The oil supply portion structure 12 is provided on the upper portion of the inlet pipe 14. The lower end of the inlet pipe 14 is connected to a fuel tank (not shown).

  A substantially cylindrical oil filler member 16 is formed at the upper end of the inlet pipe 14. The inside of the fuel filler member 16 is a fuel filler 26 (the center of which is indicated by the center line CL), and a fuel gun 28 is inserted into the fuel filler 26 from the opening 18 at the upper end to supply fuel to the fuel tank. It is possible.

  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 is rotatably attached to the fuel filler member 16 by a hinge 22 provided on the upper portion thereof. Then, the flapper valve 20 rotates between a closing position TP (a position indicated by a two-dot chain line) that closes the fuel inlet 26 and an open position HP (a position indicated by a solid line) that opens the fuel inlet 26. In the open position HP, the lower part of the flapper valve 20, that is, the side opposite to the side where the hinge 22 is arranged has moved greatly to the fuel tank side.

  A stopper protrusion (not shown) is formed on the inner surface of the fuel filler member 16, and the rotation range (open position) of the flapper valve 20 is limited to a predetermined range. Further, a flapper valve spring 44 is wound around the hinge 22. The flapper valve spring 44 urges the flapper valve 20 toward the closing position TP so that the oil supply port 26 is not inadvertently opened. 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 44.

  As shown in detail in FIG. 3, a wiping member 24 is provided on the inner surface of the fuel filler member 16 so as to contact the outer peripheral surface of the fuel gun 28 inserted into the fuel filler 26 from below. In the present embodiment, the fixed base 30 located on the inner peripheral side of the fuel filler member 16 is fixed, and the wiping member 24 is fixed to the fixed base 30. Note that the wiping member 24 may be integrated with the fixed base 30.

  Each of the fixed base 30 and the wiping member 24 has a tapered surface 32 on the flapper valve 20 side (opening 18 side). The tapered surface 32 guides the oil supply gun 28 to the center (center line CL) of the oil supply port 26 when the oil supply gun 28 comes into contact with the taper surface 32 during insertion.

  The upper surface of the wiping member 24 is a contact surface 34 that contacts the outer peripheral surface (surface) of the fuel gun 28. In particular, when the wiping member 24 is viewed in the direction of arrow A1 (the direction in which the fueling gun 28 is pulled out from the fueling port 26), the radius of curvature of the contact surface 34 is equal to the radius of curvature of the outer peripheral surface of the fueling gun 28. The surface 34 is curved so as to make surface contact with the outer peripheral surface of the fuel gun 28. When the fuel gun 28 is pulled out from the fuel filler port 26 in a state where the outer peripheral surface of the fuel gun 28 is in contact with the contact surface 34, the contact surface 34 is in surface contact with the outer peripheral surface of the fuel gun 28. It has an effect of wiping off a part of the attached fuel.

  A plurality of slits 38 are formed in the wiping member 24 from the contact surface 34 side, and portions other than the slits 38 are a plurality of ribs 40. The fuel in which the outer peripheral surface of the fuel gun 28 is wiped off by the contact surface 34 temporarily flows into the slit 38. That is, the slit 38 temporarily stores the fuel wiped off from the outer peripheral surface of the fuel supply gun 28, thereby enabling effective wiping. The slit 38 is an example of an escape portion in the present invention.

  In the present embodiment, the longitudinal direction of the slit 38 is along the direction (arrow A1 direction) in which the fueling gun 28 is pulled out from the fueling port 26, and the slit 38 is open on the back side and the near side of the fueling port 26. For this reason, the fuel accommodated in the slit 38 moves in the slit 38 and flows out from the open portion to the outside of the slit 38 (inside the fuel filler opening 26).

  As shown in FIGS. 1 and 2, a guide convex portion 36 is formed on the inner surface of the fuel filler member 16 at a position facing the wiping member 24 with the inserted fuel gun 28 interposed therebetween. The guide convex portion 36 has a guide portion 36 </ b> S whose central portion on the lower surface is curved in an arc shape with the same curvature as the fuel gun 28.

  The guide convex portion 36 also has a tapered surface on the flapper valve 20 side (opening portion 18 side) that guides the fuel gun 28 to the center (center line CL) of the fuel port 26 when the fuel gun 28 is inserted into the fuel port 26. 42 is formed.

  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. 1, the flapper valve 20 receives the biasing force of the flapper valve spring to maintain the closed position TP, and the fuel supply port 26 is closed.

  When refueling, the refueling gun 28 is inserted into the refueling port 26. The biasing force of the flapper valve spring 44 is set to be smaller than the pressing force applied from the fuel gun 28, and the flapper valve 20 pushed by the fuel gun 28 rotates to the open position HP. It can be inserted further into the back.

  During the insertion of the fuel gun 28, the tip of the fuel gun 28 may come into contact with either the tapered surface 32 or the tapered surface 42. In this state, when the fueling gun 28 is further inserted into the interior of the fueling port 26, the fueling gun 28 is guided toward the center of the fueling port 26 by the tapered surface 32 or the tapered surface 42. Refueling can be performed with the fuel gun 28 inserted to a predetermined position. Further, in a state where the fueling gun 28 is inserted to a predetermined position of the fueling port 26 and fueled, the contact surface 34 is in contact with the fueling gun 28 and the fueling gun 28 is stably supported.

  When the fueling gun 28 is pulled out from the fueling port 26, the fueling gun 28 is pulled out while maintaining the state where the contact surface 34 is in contact with the outer peripheral surface of the fueling gun 28. For this reason, even if fuel adheres to the outer peripheral surface of the fuel gun 28, at least a part of the fuel is wiped off by the contact surface 34 and removed from the outer peripheral surface of the fuel gun 28. For this reason, it is possible to suppress the fuel adhering to the fuel supply gun 28 from flowing down outside the fuel supply port 26 (for example, a panel of the vehicle body) (so-called liquid dripping). In particular, in the first embodiment, since the wiping member 24 is fixed to the fuel filler port member 16, the contact state of the contact surface 34 with the outer peripheral surface of the fuel gun 28 can be stably maintained.

  Moreover, in the first embodiment, the wiping member 24 is located below the fuel filler 26, and the contact surface 34 is in contact with the fuel gun 28 inserted into the fuel filler 26 from below. On the outer peripheral surface of the fuel gun 28, the fuel tends to adhere downward due to gravity. However, since the contact surface 34 contacts the outer peripheral surface of the fuel gun 28 from below, the fuel can be effectively wiped off.

  In addition, in the first embodiment, a slit 38 is formed on the contact surface 34 of the wiping member 24, and a part of the wiped fuel is dropped into the slit 38 and accommodated. Therefore, in the operation of pulling out the fuel gun 28 from the fuel filler port, the fuel can be effectively wiped from the outer peripheral surface of the fuel gun 28. The fuel contained in the slit 38 (the wiped fuel) flows out into the fuel filler opening 26 from the open part on the back side or the near side of the slit 38.

  When the fueling gun 28 is completely pulled out from the fueling port 26, the flapper valve 20 is rotated to the closed position TP as shown by a two-dot chain line in FIG. Occlude.

  FIG. 4 shows an enlarged view of the wiping member 54 applied to the oil supply portion structure of the first modification of the first embodiment. The wiping member 54 of the first modification is integrated with the fixed base 30. Further, in the wiping member 54 of the first modified example, the shape of the slit 58 formed on the contact surface 34 is different from that of the first embodiment, but the other configuration is the same.

  That is, as shown in detail in FIG. 5, the slit 58 of the first modification is entirely or partially in the longitudinal direction (in the example shown in FIG. 5, an intermediate portion in the longitudinal direction). It is inclined with respect to the direction of arrow A1. Then, when viewed in the direction of the arrow A1, a gap due to the slit 58 is not generated. For example, assuming an arbitrary auxiliary line A2 parallel to the arrow A1 in the slit 58, the auxiliary line A2 does not penetrate from the one end side of the slit 58 to the other end side (the right side to the left side in FIG. 5). In other words, when the outer peripheral surface of the fuel gun 28 is in contact with the contact surface 34 and moves in the direction of the arrow A1, the contact surface 34 is wide in the circumferential direction of the outer peripheral surface of the fuel gun 28 (range without a gap). The fuel can be wiped off by reliably contacting the outer peripheral surface of the fuel supply gun 28.

  FIG. 6 shows an enlarged view of the wiping member 64 applied to the oil supply portion structure of the second modification of the first embodiment. Also in the wiping member 64 of the second modified example, the wiping member 64 is integrated with the fixed base 30. The slits 68 formed on the contact surface 34 are wider than the slits 38 of the first embodiment, and the number of slits 68 is smaller than that of the first embodiment. is there.

  Therefore, also in the second modification, the fuel can be accommodated in the slit 68 in the slit 68 wiped from the outer peripheral surface of the fuel gun 28. In the second modification, the rib 70 is thicker than the rib 40 of the first embodiment, so that the rib 40 is inadvertently deformed when the outer peripheral surface of the fuel gun 28 is in contact with the contact surface 34. Can be suppressed.

  In contrast, in the first embodiment, the slit 38 is narrower than the second modification, and by setting this width appropriately, surface tension is applied to the fuel, and the slit 38 with respect to the fuel Absorbability can be increased.

  FIG. 7 shows a partially enlarged view of the oil supply portion structure 112 according to the second embodiment of the present invention. In the second embodiment, the same components and members as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. Moreover, since the whole structure of the oil supply part structure 112 is substantially the same as the oil supply part structure 12 of 1st Embodiment, illustration is abbreviate | omitted.

  In the fuel filler structure 112 of the second embodiment, the contact surface 134 of the wiping member 124 can be in surface contact with the outer peripheral surface of the fuel gun 28 inserted into the fuel filler port 26 in the same manner as the contact surface 34 of the first embodiment. However, the slit 38 (see FIG. 3) according to the first embodiment is not formed.

  Further, a gap is formed between the fixed base 30 and the wiping member 124, and a substantially horizontal U-shaped leaf spring 138 is disposed in this gap when viewed in the direction of the arrow B1. The leaf spring 138 holds the wiping member 124 at a predetermined position, and the contact surface 134 is slightly closer to the center line CL than the contact surface 34 in the first embodiment.

  Therefore, when the fueling gun 28 is inserted into the fueling port 26, the contact surface 34 is pushed by the outer peripheral surface of the fueling gun 28 and slightly moves away from the center line CL. And the urging | biasing force of the direction which goes to the centerline CL is made to act on the wiping member 124 because the leaf | plate spring 138 elastically deforms. In the second embodiment, the fixed pedestal 30 and the leaf spring 138 constitute a pressing support member according to the present invention.

  The leaf spring 138 also has a tapered surface 32 on the flapper valve 20 side (opening 18 side).

  Also in the oil supply part structure 112 of 2nd Embodiment set as such a structure, there exists an effect similar to the oil supply part structure 12 of 1st Embodiment.

  In particular, in the oil supply portion structure 112 of the second embodiment, when the oil supply gun 28 is pulled out from the oil supply port 26, even if the oil supply gun 28 moves in the vertical direction (arrow C1 direction), the urging force of the leaf spring 138 is a wiping member. By acting on 24, the contact surface 34 can be kept in contact with the outer peripheral surface of the fuel gun 28.

  Further, even when the fuel gun 28 does not move in the direction of the arrow A1, the contact surface 34 can be pressed against the outer peripheral surface of the fuel gun 28 by the urging force of the leaf spring 138, so that the fuel can be wiped more reliably from the outer peripheral surface of the fuel gun 28. It becomes possible to take.

  FIG. 8 shows an oil supply portion structure 212 according to the third embodiment of the present invention. In the third embodiment, the same components and members as those in the first embodiment or the second embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  In the oil supply portion structure 212 of the third embodiment, the fixed base 30 (see FIGS. 1 to 3) of the first embodiment is not provided, and a second flapper valve 220 is provided instead. The second flapper valve 220 is rotatably attached to the fuel filler member 16 by a hinge 222 provided at a lower portion thereof. And by rotation, it rotates between standing position SP shown with a dashed-two dotted line, and recumbent position DP shown with a continuous line. Note that the rotation locus of the flapper valve 20 and the rotation locus of the second flapper valve 220 do not overlap.

  A second flapper valve spring 244 is attached to the hinge 222 and urges the second flapper valve 220 to rotate toward the standing position SP. The rotation of the second flapper valve 220 is limited by hitting the stopper 238 in the recumbent position, and similarly, the rotation of the second flapper valve 220 is also limited by hitting a stopper (not shown) in the standing position SP. Further, a closing member (not shown) is formed in the fuel filler member 16 so as to contact the second flapper valve 20 in the standing position SP and close the fuel filler port 26.

  The second flapper valve 220 is provided with a wiping member 224 on the rotation tip side (opposite side of the hinge 222) and on the center line CL side in the recumbent position DP. Similar to the wiping member 24 of the first embodiment and the wiping member 124 of the second embodiment, the wiping member 224 has a contact surface 34 that makes surface contact with the outer peripheral surface of the fuel gun 28 inserted into the fuel filler port 26. Is formed. The wiping member 224 faces the guide convex portion 36 with the fuel gun 28 interposed therebetween when the second flapper valve 220 is in the recumbent position DP. In the third embodiment, the second flapper valve 220 and the second flapper valve spring 244 constitute a pressing support member according to the present invention.

  In the oil supply portion structure 212 of the third embodiment having such a configuration, the oil supply port 26 is normally double-closed by the second flapper valve 220 in addition to the flapper valve 20.

  When the fueling gun 28 is inserted into the fueling port 26, first, the flapper valve 20 is pushed by the fueling gun 28 to the open position HP, and then the second flapper valve 220 is pushed by the fueling gun 28 to reach the recumbent position DP. Become. As a result, the fuel filler port 26 is opened and fuel can be supplied. In the middle of insertion of the fuel gun 28, when the tip of the fuel gun 28 contacts the tapered surface 32 or the tapered surface 42, the fuel gun 28 is guided to the center of the fuel inlet 26.

  When the fueling gun 28 is pulled out from the fueling port 26, the contact surface 34 is maintained in contact with the outer peripheral surface of the fueling gun 28, so that part of the fuel adhering to the outer peripheral surface of the fueling gun 28 is also contacted by the contact surface 34. It is wiped off and removed from the outer peripheral surface of the fuel gun 28, so-called dripping can be suppressed.

  Moreover, in the third embodiment, the second flapper valve 220 is urged from the recumbent position DP toward the standing position SP by the rotational urging force of the coil spring, so that the contact surface 34 is also applied to the outer peripheral surface of the fuel gun 28. A pressing force acts. For this reason, even when the oil supply gun 28 moves in the vertical direction (arrow C1 direction) when the oil supply gun 28 is pulled out from the oil supply port 26, the contact surface 34 can be kept in contact with the outer peripheral surface of the oil supply gun 28. . Further, even when the fuel gun 28 does not move in the direction of the arrow C 1, the contact surface 34 is pressed against the outer peripheral surface of the fuel gun 28 by the urging force of the leaf spring 138, and the fuel is more reliably wiped off from the outer peripheral surface of the fuel gun 28. It becomes possible.

  In the third embodiment, it is possible to close the fuel filler port 26 only by the flapper valve 20, and in this case, the second flapper valve 220 acts to close the fuel filler port 20 at the standing position SP. It may not have.

  In the second embodiment and the third embodiment, slits 38, 58, 68 and the like may be formed on the contact surface 34 as in the first embodiment. However, in the second and third embodiments, the urging force of the leaf spring 138 or the coil spring 238 acts on the wiping members 124, 224, so that the ribs 40 are formed too much by forming the slits 38, 58, 68, etc. When it becomes thin, the rib 40 is pressed against the outer peripheral surface of the fuel gun 28 and easily falls down. Therefore, it is preferable that the rib has a sufficient width so that such a fall can be suppressed. Of course, on the contrary, the slit 38 does not need to be formed in the wiping member 24 of the first embodiment.

  The escape portion of the present invention is not limited to these slits 38, 58, 68, etc. In short, the fuel that has been wiped off from the outer peripheral surface of the fuel gun 28 is allowed to escape to a position away from this outer peripheral surface. What is necessary is just to be able to suppress the reattachment of the fuel to 28. For example, a structure including one or a plurality of depressions (recesses) formed in the contact surface 34 and a discharge flow path or an outflow hole for discharging the fuel accumulated in the depressions from each of the depressions may be used.

  Moreover, in each said embodiment, although the thing of the structure which provided the wiping member in the back | inner side of the fuel filler opening 26 rather than the flapper valve 20 is mentioned as an example, the wiping member 24 is located in front of the flapper valve 20. It may be provided. If the wiping member 24 is provided on the back side of the flapper valve 20 as in each embodiment, the adhesion of fuel to the flapper valve 20 (transfer from the fuel gun 28) can be suppressed.

  The wiping members 24, 124, and 224 are not limited to those having a structure that comes into contact with the outer peripheral surface of the fuel gun 28 pulled out from the fuel filler port 26 from the lower side, and, for example, contact over the entire circumference of the surface of the fuel gun 28. It may be a structure. Furthermore, even if it contacts the outer peripheral surface of the fuel gun 28 from above, the fuel can be wiped off at the contacted portion.

  The material of the wiping members 24, 124, and 224 is not particularly limited as long as the fuel can be wiped off while maintaining good contact with the outer peripheral surface of the fuel gun 28, but the wiping that does not form the slit 38 is possible. In the case of a take-off member, for example, resin, rubber or elastomer can be applied. Even with the wiping member in which the slit 38 is formed, these resins, rubbers, or elastomers can be applied as long as the rib 40 can have a predetermined rigidity. In particular, with rubber and elastomer, the contact angle when the fuel comes into contact generally increases, and the wiping member does not get wet by the fuel (the fuel is repelled by the wiping member), so that the wiping member runs out of fuel well. Become.

  The opening / closing valve of the present invention is not limited to the flapper valve 20 described above, and may be any valve that can reliably open and close the fuel filler opening. In the structure using the flapper valve 20, the position of the hinge 22 is not limited. For example, the hinge 22 may be provided in the lower part of the flapper valve 20 to form a so-called downwardly opened flapper valve. In such an open flapper valve, it is preferable to provide wiping members 24, 124, and 224 on the back side of the flapper valve to suppress the transfer (attachment) of fuel from the fuel supply gun 28 to the flapper valve.

  Furthermore, the present invention can be applied to an oil supply portion (for example, a structure that is opened and closed by a cap or the like) that does not have an opening / closing valve such as the flapper valve 20.
