Description

The present invention relates to a filler pipe in which a retainer and a fuel gun holding member are attached to an inlet portion of a filler pipe that injects fuel from a fuel filler port to a fuel tank for an automobile.

As shown in FIG. 13, a filler pipe 110 is attached to inject fuel from a vehicle body filler port provided in the vehicle body into an automobile fuel tank.
Fuel is injected into the filler pipe 110 by inserting the tip portion 141 of the fuel gun 140 into the inlet 111.

  At this time, in order to hold the fuel supply gun 140 and stabilize the fuel flow, the retainer 120 is provided inside the inlet 112 of the filler pipe 110, and the tip of the retainer 120 is formed to be elongated in a pipe shape. There are some (for example, refer to Patent Document 1). In this case, the front end portion 141 of the fuel supply gun 140 is held at the front end portion of the retainer 120 so that the front end portion 141 of the fuel supply gun 140 always faces the same direction.

However, in this case, since the retainer 120 is formed as a separate part and the tip portion of the retainer 120 is elongated in a pipe shape, the overall weight of the retainer 120 increases, which is against the request for weight reduction of the vehicle body. Become.
In addition, in order to hold the front end portion 141 of the fuel gun 140, the pipe diameter of the front end portion of the retainer 120 needs to be approximately equal to the nozzle diameter of the front end portion 141 of the fuel gun 140. It took a lot of time to insert and take out.

  When the front end portion of the retainer 120 is not extended long, the refueling gun 140 can insert the front end portion 141 of the refueling gun 140 until it contacts the filler pipe 110. Therefore, the position of the front end portion 141 of the refueling gun 140 is the filler. The fuel flow greatly deteriorated in the pipe 110, and the fuel flow deteriorated, or the fuel flowed back and the auto stop sensor of the fuel gun 140 acted in the middle of the fuel supply.

  Further, when the fueling gun 140 is inserted all the way into the filler pipe 110, the fueling gun 140 may be sandwiched between the filler pipe 110 and the retainer 120 and may be difficult to come off. Further, when the refueling gun 140 is inserted all the way into the filler pipe 110, the body portion of the refueling gun 140 and the vehicle body may interfere with each other.

Therefore, as shown in FIG. 14, there is one in which a position regulating member 230 of the filler pipe 210 is provided at the inlet portion 212 of the filler pipe 210 (see, for example, Patent Document 2). In this case, the position restricting member has a stopper 232 that restricts the entry of the front end 241 of the fuel gun 240 and a fixing member 231 that is attached to the inside of the filler pipe 210.
However, the stopper 232 merely restricts the entry of the tip portion 241 of the fuel gun 240, and the tip portion 241 of the fuel gun 240 cannot be stably held.

Therefore, as shown in FIG. 16, a retainer 320 is attached to the inlet 312 of the filler pipe 310, and an oil supply gun holding member 330 that holds the tip of the oil supply gun is attached to the tip of the retainer 320.

The oil supply gun holding member 330 is in contact with the inner surface of the retainer 320 to hold the oil supply gun holding member 330, the holding member main body 331 extending from the holding member attaching portion 332, and the holding member A holding member distal end portion 333 that extends from the main body portion 331 and holds the distal end portion 341 of the fuel gun 340 is provided.
The holding member tip end portion 333 is formed with a holding member tip end locking piece 334 that locks the tip end portion 341 of the fueling gun 340 and stops entry.

However, since the holding member front end locking piece 334 is provided not on the bottom surface of the holding member front end portion 333 but on the side portion as shown in FIGS. 17 and 18, the front end portion 341 of the fuel gun 340 is refueled. In some cases, the flow of the injected fuel on the side of the fuel hits the holding member front end locking piece 334 and scatters into a droplet, which is blown out from the injection port.

In addition, the oil supply gun holding member 30 can reliably hold the tip 41 of the oil supply gun 40 and has high durability. The retainer 20 may be made of metal, and the oil supply gun holding member 30 may be made of synthetic resin.

The holding member mounting portion 32 is inserted into the inner surface of the retainer holding portion 26 and is fixed to the inner surface of the retainer holding portion 26. Since the holding member attaching portion 32 of the oil gun holding member 30 is attached in close contact with the inner surface of the retainer holding portion 26, as shown in FIG. 11, the fuel gun that reliably enters the oil gun holding member 30 from the retainer holding portion 26. Forty tips 41 can be held.
The holding member mounting portion 32 is formed in a cylindrical shape, and a holding member mounting portion seal protrusion 32a is formed on the outer periphery.

As shown in FIG. 1, holding member attachment portion locking pieces 32 b are formed on both sides of the side surface of the holding member attachment portion 32. The holding member mounting portion locking piece 32 b is formed with a holding member mounting portion locking piece protrusion 32 c extending in the radial direction at the center portion, and the holding member mounting portion locking piece protrusion 32 c is the retainer holding portion 26 of the retainer 20. An oil supply gun holding member 30 is attached to the retainer holding portion engaging hole 26a or the engaging concave portion formed in FIG. A holding member attachment portion locking groove 32d is formed on three sides around the holding member attachment portion locking piece 32b so that the holding member attachment portion locking piece 32b can be bent.

Next, the holding member main body 31 of the fuel gun holding member 30 will be described. The holding member main body 31 is formed in a cylindrical shape having a smaller diameter than the holding member mounting portion 32, and the holding member main body 31 and the holding member mounting portion 32 are integrally formed continuously with an inclined surface. A holding member attaching portion rib 32e is formed on the outer surface of the inclined surface. A holding member main body rib 31 a is formed on the upper portion of the holding member main body 31. For this reason, as shown in FIG. 11, the fuel supply gun holding member 30 can be stably attached to the retainer 20 by the holding member main body portion rib 31a and the holding member attachment portion rib 32e.

An open holding portion upper opening 37 is formed on the distal end side of the holding member main body portion 31 of the fuel gun holding member 30 and the upper surface of the holding member distal end portion 33 described later. Since the holding portion upper side opening 37 is formed, the upper surface of the oil supply gun holding member 30 is opened, and the holding member tip locking piece 34 described later locks the tip portion 41 of the fuel gun 40 together with oil supply. It is possible to prevent the tip portion 41 of the gun 40 from being pinched by the fuel gun holding member 30, and the fuel gun 40 can be easily inserted and removed.

A holding member distal end portion 33 is formed on the distal end side of the holding member main body portion 31. The holding member front end portion 33 is formed on a holding portion front end holding piece 33c that holds the lower surface of the front end portion 41 of the fuel gun 40 and an inner surface (upper side surface in FIG. 1) of the holding portion front end holding piece 33c. A holding member tip locking piece 34 for locking the tip 41 is formed. As shown in FIG. 11, the holding member distal end portion 33 is inserted to the vicinity of the main body portion of the filler pipe 10.

  As shown in FIG. 11, the holding portion tip holding piece 33 c is formed below the holding member tip portion 33. The holding portion tip holding piece 33c holds the tip portion 41 of the fuel gun 40 by holding the tip portion 41 of the fuel gun 40 with the holding member tip locking piece 34 while holding the tip portion 41 of the fuel gun 40. The position of the front end portion 41 of the fuel gun 40 can be stopped at a predetermined position so as not to enter the back of the filler pipe 10 (in the fuel tank direction) from the member front end locking piece 34. Therefore, the tip portion 41 of the fuel gun 40 can be stabilized, and fuel can be supplied with a stable fuel flow from the fuel gun 40 into the filler pipe 10.

In the embodiment shown in FIGS. 2 to 4, three holding member tip locking pieces 34 are formed in a strip shape and are formed in parallel to the longitudinal direction of the fuel gun holding member 30.
The holding member tip locking piece 34 has a length in the longitudinal direction (indicated by A in FIG. 3) of about 10 to 15 mm and a height (indicated by B in FIG. 4) of 1.5 to 3 mm. The thickness and thickness (indicated by C in FIG. 3) are about 1 to 2 mm. The distance between the holding member tip locking piece 34 and the holding member tip locking piece 34 (indicated by D in FIG. 3) is about 2 to 4 mm.

  The three holding member tip locking pieces 34 have a central holding member tip locking piece 34 along a holding portion tip holding piece 33c whose cross section is formed in the same arc shape as the inner surface of the holding member main body 31. The holding member tip locking pieces 34 on both sides are formed high, and the tips of the three holding member tip locking pieces 34 are arcuate.

  As shown in FIG. 4, the three holding member tip holding pieces 34 are formed below the holding portion tip holding piece 33c, and are within a range of an arc 90 degrees below the arc of the holding portion tip holding piece 33c ( It is preferable to form it in a range indicated by E in FIG. When formed at the lower part of the holding portion tip holding piece 33c, it becomes easier to lock the tip portion 41 of the fuel gun 40, and the fuel released from the tip portion 41 of the fuel gun 40 hits the holding member tip locking piece 34. Even if the fuel splashes, since the splashes flow into the filler pipe 10 due to the main flow of the fuel released from the tip portion 41 of the fuel gun 40, the fuel can be prevented from scattering to the outside.

  In addition, as shown in FIG. 5, the holding member front-end | tip locking piece 34 can be made into 1 sheet, and as shown in FIG. 6, the holding member front-end | tip locking piece 34 can also be made into 2 sheets. In this case, the flow of the fuel discharged from the tip 41 of the fuel gun 40 is less disturbed and the splashes are less likely to scatter.

Furthermore, the holding member tip locking piece 34 can be formed at right angles to the longitudinal direction of the holding portion tip holding piece 33c. In this case, even if the position of the tip 41 of the fuel gun 40 varies, the tip 41 of the fuel gun 40 can be reliably held by the holding member tip locking piece 34. Similarly to the above, even if the fuel released from the tip 41 of the fuel gun 40 hits the holding member tip locking piece and scatters, the main flow of fuel released from the tip 41 of the fuel gun 40 Since the splashes flow into the filler pipe 10, it is possible to prevent the fuel from being scattered outside.

As shown in FIGS. 1 and 11, the holding member distal end portion 33 of the fuel gun holding member 30 has a holding portion auto stop sensor hole in a portion corresponding to the auto stop sensor 42 attached to the distal end portion 41 of the fuel gun 40. 35 is formed. For this reason, when the fuel tank becomes full during refueling of the refueling gun 40, the auto stop sensor 42 can reliably detect the fuel from the holding portion auto stop sensor hole 35, and the auto stop sensor 42 can work. Can be prevented.

Next, the operation of inserting the tip 41 of the fuel gun 40 from the retainer injection edge 21 of the retainer 20 will be described.
As shown in FIG. 11, when the distal end portion 41 of the fuel gun 40 is inserted from the retainer injection edge 21 of the retainer 20, the distal end portion 41 passes through the retainer mounting portion 22 of the retainer 20 and is attached to the retaining member of the fuel gun holding member 30. It passes through the portion 32 and the holding member main body portion 31 and reaches the holding member tip portion 33 of the fuel gun holding member 30.

Then, when fuel is injected from the tip 41 of the fuel gun 40, the fuel is injected into the fuel tank (not shown) through the filler pipe 1 as shown in FIG. At that time, as shown by the arrow in FIG. 12, the fuel hits the holding member tip locking piece 34 and scatters by rebounding, but was scattered by the main flow of fuel flowing above the holding member tip locking piece 34. Since the fuel is swept away and flows from the filler pipe 10 to the fuel tank, it is not discharged from the fuel filler port.

Moreover, the holding member front end locking piece 34 does not allow the front end 41 of the fuel gun 40 to enter the back of the filler pipe 10, and insertion and extraction are easy. Furthermore, since the upper surface of the fuel gun holding member 30 is opened as the holding portion upper side opening 37, the tip end portion 41 of the fuel gun 40 is not sandwiched between the fuel gun holding members 30.
