This international application claims priority based on Japanese Patent Application No. 2014-113114 filed with the Japan Patent Office on May 30, 2014. The entire contents are incorporated by reference into this international application.

The present invention relates to an oil supply retainer.

Conventionally, a fuel inlet for injecting fuel such as gasoline into a fuel tank of a vehicle or the like is known. Generally, a fuel inlet (filler pipe) includes an inlet pipe that guides fuel from a fuel filler port to a fuel tank. An oil supply retainer separate from the inlet pipe is disposed at the oil supply side end of the inlet pipe.

For example, Patent Document 1 discloses an oil supply port structure provided with a cylindrical oil supply retainer (nozzle guide) for guiding insertion of a nozzle of an oil supply gun. This fuel filler structure is configured to restrict the insertion of the nozzle of the fuel gun by a pair of inward protrusions provided in the oil retainer.

Japanese Patent No. 52005866

However, the fuel filler structure of Patent Document 1 has the following problems. That is, since the inner peripheral surface of the cylindrical oil supply retainer (nozzle guide) protrudes inward to form the inner protrusion, the oil supply port structure is complicated. In addition, the insertion position (tip position) of the nozzle of the oil gun in the oil retainer may change depending on the diameter of the nozzle of the oil gun, the shape accuracy of the inward projection formed on the inner peripheral surface of the oil retainer, etc. There was a risk that stable oil supply could not be secured sufficiently.

In one aspect of the present invention, it is desirable to provide an oil supply retainer that can realize the restriction of insertion and position of an oil supply gun, and can improve the oil supply performance, while having a simple structure.

A retainer for refueling according to one aspect of the present invention includes a cylindrical main body portion that is inserted into an oil supply side end portion of an inlet pipe that guides fuel to a fuel tank, and the main body portion includes a distal end portion of the main body portion. And a claw part that is bent inward from the tip of the ellipse part and protrudes inwardly, and the claw part is provided at least in the ellipse part, It is provided at a position facing the ellipse in the minor axis direction.

In the oil supply retainer, the cylindrical main body portion is provided with an oval portion that forms the tip of the main body portion and has an elliptical cross section orthogonal to the axial direction. Therefore, regulation by the diameter of the fuel gun is possible in the elliptical portion. For example, insertion of a large-diameter leaded gasoline refueling gun or the like can be restricted at the ellipse. Further, since a gap can be formed between the ellipse and the fuel gun, air can be vented at the time of fuel supply, and the oil supply performance can be improved.

Also, the main body portion is provided with a claw portion that bends inward from the tip of the elliptical portion and protrudes. Therefore, the tip position of the fuel gun can be easily regulated by the claw portion. As a result, over-insertion of the fuel gun is suppressed, and stable fuel supply is possible. Further, the claw portion can be formed by bending the tip portion of the main body portion. Therefore, the claw part can be easily formed using press molding or the like, and the shape accuracy of the claw part can be increased.

Further, the claw portion is provided in the elliptical portion at a position facing at least the minor axis direction of the elliptical portion. Therefore, it is possible to reliably regulate the tip position of the fuel gun while shortening the length protruding inward from the tip of the elliptical part as much as possible. Thereby, it can suppress that a nail | claw part becomes an obstruction at the time of refueling, for example, a nail | claw part obstructs the flow of the fuel from a fueling gun. In addition, the position of the oil supply gun can be regulated by the oil supply retainer having a simple structure, and the material cost of the oil supply retainer can be reduced and the mass of the oil supply retainer can be reduced.

Thus, according to one aspect of the present invention, it is possible to provide an oil supply retainer capable of realizing the insertion restriction and the position restriction of the oil supply gun and improving the oil supply performance with a simple structure. be able to.

In the oil supply retainer, it is preferable that an inclination angle in a major axis direction of the elliptical portion with respect to a vehicle vertical direction is 75 ° or less. That is, it is preferable that the angle (90 ° or less) between the vehicle vertical direction and the major axis direction of the ellipse is in the range of 0 ° to 75 °. In this case, even if the refueling gun is inserted obliquely with respect to the vehicle vertical direction, the posture of the refueling gun is determined in the major axis direction of the elliptical portion, so that variations in the posture of the refueling gun can be suppressed. Thereby, the attitude | position (direction) of the fueling gun at the time of fueling can be made constant, and the stable fueling by a fueling gun is attained.

The main body includes a first part constituting a base end part thereof, and a second part fixed to the first part and provided with the ellipse part and the claw part, the second part being The winding pipe may be used. In this case, the 2nd component which comprises the front-end | tip part of the main-body part and was provided with the ellipse part and the nail | claw part can be manufactured easily. In addition, even when the total length of the oil supply retainer is long and it is difficult to manufacture by conventional methods such as drawing, the oil supply retainer can be manufactured by using a part of the oil supply retainer (second part) as a wound pipe. Becomes easy. The wound pipe refers to one obtained by winding a plate material into a cylindrical shape, butting one end edge portion and the other end edge portion of the plate material together by welding or the like.

Also, a sensor notch for exposing the auto-stop sensor of the fueling gun inserted into the main body, and a notch for the sensor are cut out from the tip of the main body to remove air from the sensor. The air vent cutout portion may be formed. In this case, the auto-stop sensor of the fueling gun can be exposed at the sensor notch. Thereby, the auto-stop sensor of the fuel gun can be surely reacted when refueling is completed, and fuel blowback during fueling can be suppressed. In addition, air can be vented at the time of refueling at the notch portion for air venting, and the oiling property can be improved. Further, it is not necessary to form a through hole for air bleeding in the main body, and the structure can be simplified and the manufacturing can be facilitated.

In the oil supply retainer, the “base end portion” of the main body portion is an end portion on the oil supply side of the main body portion, and the “tip portion” of the main body portion is opposite to the oil supply side of the main body portion ( It is the end of the fuel tank side.

The fuel inlet is a part for an automobile and is used to inject fuel into a fuel tank. The fuel inlet includes an oil supply retainer 1, an inlet pipe 5, a breather tube (not shown), and the like.

The inlet pipe 5 is a cylindrical pipe. The inlet pipe 5 forms a fuel supply path for guiding fuel (gasoline or the like) from the fuel filler opening to the fuel tank. The inlet pipe 5 of the first embodiment is made of metal. An injection portion 51 having an enlarged diameter is formed at an end portion on the oil supply side of the inlet pipe 5, that is, an end portion (upstream end portion) on the upstream side of the fuel supply path. An air filter (not shown) is provided on the outer periphery of the upstream end of the injection part 51.

Breather tube is a cylindrical pipe. The breather tube guides air containing fuel vapor in the fuel tank, so-called vapor, to the upstream side of the inlet pipe 5 and forms an air vent path for reducing the internal pressure of the fuel tank. The breather tube of the first embodiment is made of metal. The breather tube is connected to the inlet pipe 5 in a state where the tip of the breather tube penetrates the inlet pipe 5. The breather tube is fixed to the inlet pipe 5 by brazing, for example.

As shown in FIGS. 1 to 3, the injection part 51 of the inlet pipe 5 is provided with an oil supply retainer 1 which is a separate part from the inlet pipe 5. The oil supply retainer 1 is a cylindrical part into which the nozzle 61 of the oil supply gun 6 is inserted. The oil supply retainer 1 according to the first embodiment is made of metal. The oil supply retainer 1 includes a cylindrical main body portion 2 that is inserted into the injection portion 51 of the inlet pipe 5.

The main body part 2 is fixed to the injection part 51 by welding or the like in a state where a part of the main body part 2 is inserted into the injection part 51 of the inlet pipe 5. The main body 2 includes a first part 21 and a second part 22 that are two separate parts. The first component 21 constitutes a proximal end side portion including the proximal end portion 201 of the main body 2. The second component 22 constitutes a distal end side portion including the distal end portion 202 of the main body portion 2.

The first component 21 is a cylindrical component having openings at both

end portions

211 and 212. The first component 21 is formed by drawing. Since the first component 21 is a component that constitutes a fuel filler port portion that requires a predetermined strength, the material is thicker than the inlet pipe 5 or the like (for example, a stainless steel plate having a thickness of 1.2 mm). It is formed with.

The outer diameter of the first component 21 varies depending on the position of the first component 21 in the axial direction. The central axis of the first component 21 is constant (coaxial) regardless of the position of the first component 21 in the axial direction. Specifically, in the first component 21, a portion where the outer diameter of the upstream end portion 211 is larger than the inner diameter of the injection portion 51 is formed at the upstream end portion (upstream end portion 211) of the fuel supply path. ing. The upstream end portion 211 is disposed in a state exposed to the outside of the injection portion 51, and forms an oil supply port for inserting the nozzle 61 of the oil supply gun 6. On the inner peripheral surface of the upstream end portion 211, a screw portion (spiral engagement portion) 31 that is a detaching mechanism for detaching a fuel cap (not shown) is formed. The screw portion 31 plays a role of latching (locking) the fuel gun 6 (nozzle 61) when the fuel gun 6 is inserted.

On the other hand, in the first component 21, the end portion (downstream end portion 212) on the downstream side of the fuel supply path is formed in a cylindrical shape so that the outer diameter of the downstream end portion 212 is smaller than the inner diameter of the injection portion 51. Has been. The end surface of the downstream end portion 212 is formed flat over the entire circumference (in a shape cut along a plane orthogonal to the axial direction).

In the first part 21, the central part 213 sandwiched between the upstream end part 211 and the downstream end part 212 has an outer diameter corresponding to the inner diameter of the injection part 51 (for example, the inner diameter of the injection part 51). And is formed in a cylindrical shape so as to have the same or slightly smaller dimensions. The central part 213 is inserted into the injection part 51. The central part 213 is fixed to the injection part 51 by welding or the like so that there is no gap over the entire circumference at the upstream end of the injection part 51.

The second part 22 is a cylindrical part having both axial ends opened. The second part 22 is constituted by a wound pipe. The second component 22 is formed by winding a stainless steel plate into a cylindrical shape, butting one end edge portion of the plate material with the other end edge portion, and welding the butted portion 41. In the first embodiment, the second component 22 is formed of the same material as the first component 21 with the same thickness and material.

In the second component 22, the end (upstream end 221) on the upstream side of the fuel supply path has an inner diameter corresponding to the outer diameter of the downstream end 212 of the first component 21 (for example, the downstream end). It is formed in a cylindrical shape so as to have a size that is the same as or slightly larger than the outer diameter of the portion 212.

On the other hand, in the second component 22, an end portion (downstream end portion 222) on the downstream side of the fuel supply path is formed with an elliptical portion 42 having an elliptical cross section perpendicular to the axial direction. The oval part 42 constitutes the tip part 202 of the main body part 2.

As shown in FIG. 5, in the cross section orthogonal to the axial direction of the second component 22, the shape of the inner peripheral surface (inner peripheral shape) of the elliptical portion 42 is an elliptical shape. When the major axis of the ellipse formed by the inner peripheral surface of the ellipse portion 42 is D1 and the minor axis is D2, the relationship of major axis D1> minor axis D2 is satisfied. The short diameter D <b> 2 is set to a dimension that is slightly larger than the outer diameter of the nozzle 61 of the fuel gun 6 (so that some margin is generated). The short diameter D2 is set smaller than the outer diameter of the nozzle of the leaded gasoline fuel gun.

The inclination angle α in the major axis direction E1 of the elliptical portion 42 with respect to the vehicle vertical direction X (not shown in FIG. 5; refer to FIG. 7 described later as appropriate) is set to 75 ° or less. In the first embodiment, the inclination angle α is 0 °. That is, the major axis direction E1 of the elliptical portion 42 is the same direction as the vehicle vertical direction X. The minor axis direction E2 of the oval part 42 is a direction orthogonal to the vehicle vertical direction X.

As shown in FIGS. 3 to 5, the inner peripheral surface of the downstream end 222 of the second component 22 (the tip 202 of the main body 2) is the downstream end of the second component 22 (the tip of the main body 2). A tapered portion 43 is provided that is inclined radially inward toward the inner side. The taper portion 43 guides the nozzle 61 of the fuel gun 6 and directs the tip of the nozzle 61 toward the opening of the downstream end portion 222 of the second component 22 (opening of the tip portion 202 of the main body portion 2) to enhance the oil supply performance. Play a role. The tapered portion 43 is not formed over the entire circumference in the downstream end portion 222 of the second component 22, but is formed in a part in the circumferential direction. The tapered portion 43 may be formed over the entire circumference in the downstream end 222 of the second component 22.

A pair of claw portions 44 are provided at the downstream end 222 of the second component 22 (the front end 202 of the main body 2). The pair of claw portions 44 is provided in the elliptical portion 42 at a position facing the minor axis direction E <b> 2 of the elliptical portion 42. The nail | claw part 44 is formed by bending the front-end | tip part of the main-body part 2 by press molding.

As shown in FIGS. 3 and 4, the downstream end 222 of the second component 22 (the distal end 202 of the main body 2) is cut out from the downstream end of the second component 22 (the distal end of the main body 2). A sensor cutout 45 for exposing the autostop sensor 62 disposed in the nozzle 61 of the fuel gun 6 is formed. The auto stop sensor 62 stops the supply of fuel from the nozzle 61 of the fuel gun 6 when the fuel exceeds a certain amount.

In the second part 22, the central part 223 sandwiched between the upstream end part 221 and the downstream end part 222 has an inner diameter of the central part 223 smaller than an inner diameter of the upstream end part 221, and is smaller than an inner diameter of the downstream end part 222. It is formed in a cylindrical shape so as to be large. The central portion 223 is formed with a reduced diameter portion 46 that gradually decreases in diameter (inner diameter and outer diameter) from the upstream end 221 toward the downstream end 222. The reduced diameter portion 46 serves to guide the nozzle 61 of the fuel gun 6 inserted into the main body 2 of the fuel retainer 1.

As shown in FIG. 3, a plurality of air vents for allowing the vapor supplied from the breather tube to the upstream side of the inlet pipe 5 to pass through the central part 223 of the second part 22 and discharging to the outside. A hole 47 is formed. The vapor from the breather tube is supplied to the downstream side of the fuel supply path in the inlet pipe 5 relative to the fuel supply retainer 1. Therefore, in order for the vapor to be discharged to the outside, the vapor needs to pass (pass through) the oil supply retainer 1. The air vent hole 47 forms a vapor passage path when the vapor passes through the oil supply retainer 1.

1 and 2, the second component 22 is fixed to the first component 21. The second part 22 constitutes the main body 2 together with the first part 21. Specifically, the upstream end 221 of the second component 22 is attached to the downstream end 212 of the first component 21 so as to cover the downstream end 212 of the first component 21 from the outside. The upstream end 221 of the second component 22 is fixed to the downstream end 212 of the first component 21 by welding or the like (for example, spot welding). As a result, when the nozzle 61 of the oil supply gun 6 is inserted into the main body 2 of the oil supply retainer 1, the nozzle 61 is prevented from being caught at the fixed portion between the first component 21 and the second component 22, thereby smoothing the nozzle 61. Can be inserted into.

Next, the effect of the oil supply retainer 1 according to the first embodiment will be described.
In the oil supply retainer 1 according to the first embodiment, the cylindrical main body 2 is provided with an elliptical portion 42 that forms the tip 202 of the main body 2 and has an elliptical cross section orthogonal to the axial direction. Therefore, it is possible to regulate the elliptical portion 42 by the diameter of the fuel gun 6 (nozzle 61). For example, insertion of a large-diameter leaded gasoline refueling gun or the like can be restricted at the elliptical portion 42. Further, since a gap can be formed between the elliptical portion 42 and the fuel gun 6, air can be vented at the time of fuel supply, and the oil supply property can be improved.

Further, the main body 2 is provided with a claw portion 44 that is bent inward from the tip of the elliptical portion 42 and protrudes. Therefore, the tip position of the fueling gun 6 (nozzle 61) can be easily regulated by the claw portion 44. As a result, over-insertion of the fueling gun 6 (nozzle 61) is suppressed, and stable fueling is possible. Further, the claw portion 44 can be formed by bending the tip portion of the main body portion 2. Therefore, the claw part 44 can be easily formed using press molding or the like, and the shape accuracy of the claw part 44 can be increased.

Further, the claw portion 44 is provided in the elliptical portion 42 at a position facing the minor axis direction E2 of the elliptical portion 42. Therefore, the tip position of the oil supply gun 6 (nozzle 61) can be reliably regulated while shortening the length protruding inward from the tip of the elliptical portion 42 as much as possible. Thereby, it can suppress that the nail | claw part 44 becomes an obstruction at the time of refueling, for example, the nail | claw part 44 obstructs the flow of the fuel from the fuel supply gun 6. FIG. Further, the position of the oil supply gun 6 can be regulated by the oil supply retainer having a simple structure, and the material cost of the oil supply retainer 1 can be reduced and the mass of the oil supply retainer 1 can be reduced.

Further, in the oil supply retainer 1 of the first embodiment, the inclination angle α in the major axis direction E1 of the elliptical portion 42 with respect to the vehicle vertical direction X is 75 ° or less. In the first embodiment, the angle is 0 °. That is, the major axis direction E1 of the elliptical part 42 and the vehicle vertical direction X are the same direction. For this reason, even if the fueling gun 6 is inserted obliquely with respect to the vehicle vertical direction X, the posture of the fueling gun 6 is determined in the major axis direction E1 of the elliptical portion 42. Therefore, variations in the posture of the fueling gun 6 can be suppressed. Thereby, the attitude | position (direction) of the oil supply gun 6 at the time of oil supply can be made constant, and the stable oil supply by the oil supply gun 6 becomes possible.

The main body 2 includes a first part 21 constituting the base end part 201, and a second part 22 fixed to the first part 21 and provided with an oval part 42 and a claw part 44. The component 22 is composed of a wound pipe. Therefore, the 2nd component 22 which comprises the front-end | tip part 202 of the main-body part 2, and was provided with the ellipse part 42 and the nail | claw part 44 can be manufactured easily. Further, even when the entire length of the oil supply retainer 1 becomes long and it is difficult to manufacture by a conventional drawing method or the like, a part of the oil supply retainer 1 (second part 22) is used as a winding pipe. The retainer 1 can be easily manufactured.

Further, a sensor notch 45 for exposing the auto-stop sensor 62 of the fuel gun 6 inserted into the main body 2 is formed at the distal end 202 of the main body 2. Therefore, the auto stop sensor 62 of the fuel gun 6 can be exposed at the sensor cutout 45. Thereby, the auto stop sensor 62 of the fuel gun 6 can be made to react reliably when the fuel supply is completed, and the blow-back of the fuel at the time of fuel supply can be suppressed.
