Description

  The present invention relates to an opening / closing device for a fuel filler opening and a misfueling prevention structure for putting fuel oil such as gasoline into a vehicle fuel tank.

  The fueling procedure at the fueling facility is, for example, after the outer lid provided at the fueling port of the vehicle is opened by remote control, etc., and then the fueling person removes the lid of the fueling port called the filler cap Hold a fuel gun on the fueling device side and insert it into the fuel filler port to inject a predetermined amount of fuel. After the injection, the fueling gun is returned to the original position of the fueling device, and the lid and the outer lid are tightened. The following is a problem in the above refueling work.

  The fuel refueling facility stores various fuel oils such as gasoline, high-octane oil, and light oil. Therefore, there is a risk of refueling with the wrong oil type or refueling gun. If you make a mistake between gasoline and light oil, the fuel system equipment will be damaged and expensive repair costs will be incurred. For example, as described in Patent Document 1, a detector for detecting a fuel evaporative gas and generating a detection signal is attached to the tip of the fuel gun as described in Patent Document 1, and based on the detection signal, There is a structure in which a fuel pump is operated or a valve provided in a pipe between the fuel gun and a fuel storage part is opened. Further, as described in Patent Document 2, a gasoline refueling mechanism in which a magnet A that is attracted by a magnet attached to a fuel filler port of a gasoline vehicle as a fuel filler and repels a magnet attached to a fuel filler port of a light oil vehicle is attached to a fuel gun. A structure in which a light oil supply mechanism in which a magnet B attached to a fuel gun is attracted to a magnet attached to a fuel supply port of a light oil vehicle and repelled by a magnet attached to a fuel supply port of a gasoline vehicle is incorporated in one housing. is there.

Further, when refueling, the lid is manually opened and closed so that the hand is easily soiled. If the mounting state is loose, there is a risk of fuel leakage. As a countermeasure, for example, as described in Patent Document 3, the lid body (cap with valve) is pushed open against the urging force by inserting the fuel gun into the fuel filler port, and the lid body is removed by removing the fuel gun. There is an opening and closing structure that closes. In this structure, the fuel filler opening is closed by the lid in the fuel pipe, and is also opened and closed by a lid portion provided on the outer lid (fuel filler lid).

  Among the above-described conventional techniques, in the structure of Patent Document 1, for example, a sensor that detects the type of fuel in the fuel tank, a control device that controls opening and closing of the valve of the fueling device according to the output of the sensor, and the like. It is necessary to provide a complicated and expensive system on the fueling device side. In addition, in the structure of Patent Document 2, although the structure is simple, for example, since the shape of the fuel filler port varies depending on the vehicle type or the shape of the fuel gun is not fixed, the magnet on the fuel filler side and the magnet on the fuel gun side May not be brought into contact. In addition, since the force required for inserting the fuel gun is larger than the attractive / repulsive force due to magnetic force, a magnet with extremely high magnetic force must be used, which is doubtful as practicality.

  On the other hand, in the open / close structure of Patent Document 3, the lid (cap with a valve) is kept closed by the urging force in the fuel pipe. (If this happens, the outer lid may be deformed due to a collision, etc., which may be a risk factor.) Also, if the urging force is set large to increase the sealing degree of the lid, the oil gun will be pulled out. If the fuel pipe is suddenly switched to a closed state with an impact sound and the inside of the fuel pipe is in a high pressure state with evaporating gas, it may not be able to be pushed open by the fuel gun.

An object of the present invention is to solve the above-described problems so as to prevent a fuel type from being erroneously refueled with a simple configuration, and to open and close a lid with respect to a fuel filler port more reliably and satisfactorily. the opening and closing equipment of the fuel supply port to one in which provide Hisage.

In order to achieve the above object, the invention of claim 1 comprises a lid for opening and closing a fuel filler port of a vehicle fuel tank, and a lock means for locking the lid in a closed state, A fuel filler opening / closing device that releases the locking means when the fuel is inserted into the fuel filler, the transmitter being attached to the fuel gun side, and the transmitter being provided on the fuel filler side Detecting means for detecting the transmission information of the transmission device, and the detection means and the transmission device are the transmission information of the transmission device only when the refueling gun approaches the refueling port at a normal angle within a preset range. The lock means detects the transmission information of the transmission device by the detection means, and enters the locking or unlocking mode based on the detection signal to control the open / close state of the lid With features To have.
In the above invention, the transmitting device may be a known transmitting means using light, infrared rays, electromagnetic waves, electromagnetic induction, or the like. The detection means, have good if known detection means such as an infrared sensor or an electromagnetic wave sensor which corresponds to the originating device.

According to a second aspect of the present invention, in the first aspect, the transmitting device is a magnetic force generating device, and the lock means detects the magnetic lines or magnetic poles of the magnetic force generating device with the detecting means and locks based on the detection signal. It is a release mode, and the lid can be switched to an open state.
In contrast, the invention of claim 3, in claim 1, together with the originating device is a magnetic force generating device, wherein the locking means detects the magnetic field lines or poles of the magnetic force generating device by said detecting means of the detection signal On the basis of this, it becomes a locking state, and the lid body cannot be switched to an open state.
In each of the above inventions, the magnetic force generation device may be a magnet, an electromagnet, or a similar one.

According to a fourth aspect of the present invention, in the first aspect of the present invention, in the first aspect, the fuel filler port is an outer space in which a space is defined between the fuel pipe communicating with the fuel tank and the fuel pipe-side end portion of the fuel pipe. The lid body is pivotally supported via a hinge disposed on the space portion side, and is urged to urge the lid body in the closing direction, and the lid body rotation speed. And a lock lever that is at least partially disposed in the space, and a latch lever that is protruded and retracted into the fuel pipe from one end of the case via a mechanism. And a manual push button that is provided in the vicinity of the fuel filler opening for switching the latch lever from the locking mode to the locking mode.

According to a fifth aspect of the present invention, in the opening / closing apparatus according to any one of the first to fourth aspects, the lid is in communication with the fuel tank by pressing the fuel gun while the fuel filler port is closed. It is characterized by a relief valve mechanism that allows the high-pressure gas on the side to be discharged to the outside.

In the first aspect of the invention, for example, the locking means releases the locking based on the detection signal that the detection means detects the transmission information of the other-side transmission device, so that it is optimal for the erroneous oiling prevention structure as exemplified in the embodiment. Therefore, the refueling operation can be performed reliably and easily. Also, the present invention is only when the fuel gun approaches the fuel port at a normal angle that is set in advance as a preferable insertion angle (for example, the fuel gun approaches an angle within 30 degrees with respect to the center line of the fuel port). The detecting means detects the transmission information of the transmission device. This is because, for example, the locking means is not unlocked even when the fueling gun deviates from the normal angle with respect to the fueling port, and the oiling failure caused by the fueling gun being inserted obliquely into the fueling port as in the past. It is possible to prevent the oil (for example, the oil from flowing out from the fuel filler opening) or to function as designed to detect when the fuel tank is full of fuel.

In the invention of claim 2, for example, for unlocking based on the detection signal locking means detects magnetic force lines or poles of the mating force generating device by the detection means, the oil supply preventing structure erroneous as mentioned embodiments It will be optimal, and the refueling work can be done reliably and easily. In contrast, in the invention of claim 3, for example, since the locking aspect of unlocking based on the detection signal locking means detects magnetic force lines or poles of the mating force generating device by the detection means, the embodiment It will be the most suitable for the wrong oiling prevention structure as mentioned .

In the invention of claim 4, the pivotal support portion (hinge) of the lid body for opening and closing the fuel filler opening, the urging means, the damper means, the locking means and the like for urging the lid body in the closing direction are arranged using the outer cylinder. In addition, since the rotation speed of the lid is braked by the damper means, rapid rotation and generation of abnormal noise can be eliminated even if the urging force is set large, and a lock means is provided near the oil filler opening. In addition, since it has a push button for manual unlocking, it is optimal as an opening / closing device for the fuel filler opening.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In this description, it was revealed by FIGS an opening and closing device of the fuel supply port, an example operation of a refueling preventing structure erroneous utilizing Re their details, including FIGS. 6 and 7, further 8 Reference will be made to variations of In each drawing, a part is omitted or simplified for easy understanding.

(Opening / Closing Device for Oil Filling Port) This opening / closing device 5 opens and closes the oil filling port arranged at the inner bottom portion 2a of the recess 2 provided at an appropriate position of the vehicle body panel 1 such as an automobile, and opens the nozzle portion 16 of the fuel gun 15. The revolving lid 9 is made to be able to be inserted into the fuel pipe 8 side from the fuel filler opening or made impossible to be inserted, and a lock means 11 for engaging and releasing the lid 9 in the closed state. A manual push button 12 for releasing the lock provided in the vicinity of the fuel filler opening, a winding spring 22 for urging the lid 9 in the closing direction, a damper 24 for braking the rotational speed of the lid 9 and the like It has. Further, a chip 17 incorporating a magnet 18 as a detection target and a magnetic sensor 7 for detecting a magnetic field line or a magnetic pole of the chip 17 (magnet 18) are used as an erroneous oiling prevention structure.

  The magnet 18 (chip 17) includes a permanent magnet or an electromagnet, and is an example of the transmitter of claim 1 or the magnetic force generator of claims 2 and 3. Specifically, for example, in the invention of claim 1, a transmitter using light, infrared rays, electromagnetic waves, electromagnetic induction or the like is used instead of the magnet 18 (chip 17), and the magnetic sensor 7 is used instead. Detection means using an infrared sensor, an electromagnetic wave sensor, or the like is used.

  Here, in the concave portion 2, an outer lid 3 that can be opened and closed by a remote control operation from the inside of the vehicle or an unlocking operation of an ignition key is provided on one side portion of the recess 2 via a hinge 4. Yes. As shown in FIG. 4, the fuel filler opening opens at the center of the inner bottom 2 a that defines the recess 2, and through the opening of the mounting member 2 b joined to the lower surface of the inner bottom 2 a. 8 is connected.

  That is, in this example, the fuel filler port is partitioned by the opening of the inner bottom portion 2a and the opening of the mounting member 2b, and the tip of the fuel pipe 8 connected to a fuel tank (not shown) is the opening (lower side of the mounting member 2b). It is in communication with the fuel filler opening in a state of being attached to the opening having a larger diameter. In addition, a seal member 26 is mounted on the inner end surface of the opening of the attachment member 2b (the opening having a large diameter on the lower side), and a lid 9 described later closely contacts the corresponding member with the seal member 26. It will be in a closed state. However, the structure of the fuel filler port and the connection structure between the fuel filler port and the fuel pipe 8 can be modified as necessary. Further, the seal member 29 may be attached to a corresponding portion of the lid body 9.

  Further, as shown in FIGS. 2 and 3, an outer cylinder 14 is provided on the lower surface side of the inner bottom portion 2a. . The outer cylinder 14 has a space portion that is cut off from outside air in a state where the upper side is integrated with the inner bottom portion 2a or the mounting member 2b by welding and the lower side is integrated with the outer periphery of the fuel pipe 8 by welding or the like. Forming. In this space portion, a flange 13 integrated with the outer periphery on the front end side of the fuel pipe 8 and each mechanism portion supported by the flange 13 and the like are arranged.

  A seat plate 6 is attached to the surface side of the inner bottom portion 2a. The seat plate 6 has a large opening at the center, and the opening for the fuel filler opening provided in the inner bottom portion 2a is exposed from the opening 6a. Further, the seat plate 6 includes a manual push button 12 for releasing the lock provided on a part of the surface, and a magnetic sensor 7 mounted on the periphery of the opening 6a with its detection surface inclined obliquely. Is provided. The magnetic sensor 7 detects the magnetic force of the tip 17 (magnet 18) attached to the outer periphery of the nozzle portion 16 of the fuel gun 15 on the fueling device side, and sends the detection signal to the control unit, as shown in FIG. Thus, the cylindrical magnet 18 fitted to the outer periphery of the tip of the nozzle part 16 and the protective cover 19 for retaining attached so as to cover the outer periphery of the magnet 18 integrally.

In addition, as an erroneous fueling prevention structure, instead of the above configuration, the tip 17 (magnet 18) is provided in the vicinity of the vehicle body side fueling port, and the magnetic sensor 7 is attached to the fueling gun 15 side. Then, the magnetic field lines and magnetic poles of the chip 17 (magnet 18) are detected and the detection signal is transmitted to the control unit, and the opening / closing device 5 of the present invention detects the refueling gun 15 (nozzle unit 16) based on the command signal of the control unit. You may make it accept | permit the insertion to a fuel filler port. By the way, the above-mentioned magnetic sensor 7 and chip 17 (magnet 18) are attached to the vicinity of the fuel filler opening of the vehicle, for example, after an automobile company or the like designates whether or not to attach according to the oil type. leave distributed in advance refueling facility and the other, based on the specification by the fueling facility, for example, if the vehicle is a diesel, and if attaching the tip 17 only light oil fuel gun 15, Conversely, by applying e.g. if the vehicle is diesel, there is a case for mounting the chip 17 to the gasoline fuel gun other than diesel fuel filler gun.

  2, 3, and 5, the lid 9 has an arm 21, and the space of the outer cylinder 14 from the escape portion 8 a that is cut out around the tip of the fuel pipe 8. It is connected to a pivot shaft 20 that is inserted into the space and is rotatably supported in the space via a bracket or the like. Further, the lid body 9 is urged in a closing direction for closing the fuel filler opening by a winding spring 22 which is an urging means assembled in a state of being inserted in the outer periphery of the pivot shaft 20, and in the closed state. The sealing member 26 keeps the sealing of the fuel filler opening.

  The pivot shaft 20 has a fan-shaped gear 23 mounted on one end side, and the gear 23 meshes with a gear 25 of a rotary damper 24 fixed in the outer cylinder 14 via a bracket or the like (not shown). is doing. For this reason, when the lid body 9 is closed by the urging force of the winding spring 22 from the open state of the fuel filler opening, rapid rotation is restricted by braking of the damper 24.

  Further, as shown in the enlarged portion of FIG. 5, the lid 9 described above has a substantially cap-shaped main body 9A in which a vent hole 9a is formed at the center, and a seal member 28 interposed between the main body 9A. The movable body 9B is assembled so as to be movable up and down, and the spring member 27 always biases the movable body 9 in the protruding direction with respect to the main body 9A. The lid body 9 is sealed between the main body 9 </ b> A and the movable body 9 </ b> B via the seal member 28 in the closed state in which the fuel filler opening is closed, but the movable body 9 </ b> B is the nozzle portion of the fuel gun 15. When the pressure of 16 is pushed down in the main body 9A against the urging force of the spring member 27, the high-pressure gas in the fuel pipe 8 is formed between the air holes 9a and the main body 9A and the movable body 9B. It is equipped with a so-called relief valve mechanism that enables discharge from the gap to the outside.

  The lock means 11 comprises a known magnetic lock mechanism, and as shown in FIG. 5, the case 30, the latch lever 10 protruding and retracted from one end of the case 30, and the latch lever 10 are urged in the protruding direction. A compression coil spring 31 provided in the case 30, an unlocking solenoid 32 that moves the latch lever 10 in the sinking direction against the urging force, and an unlocking mechanism for the manual push button 12. is doing.

  Among these, the case 30 is attached so that the front end faces the outer periphery of the fuel pipe 8 and the rear end penetrates the outer cylinder 14. The latch lever 10 is set to a latching claw portion whose tip is inclined on the back side, and is arranged to project into the fuel pipe from an insertion hole provided in the fuel pipe 8. The compression coil spring 31 is set so that its spring pressure is weaker than the spring pressure of the winding spring 22 on the lid 9 side. Even if the latch lever 10 protrudes into the fuel pipe 8 when the lid 9 is in the open state, the front-end locking claw portion of the latch lever 9 (the above-described rear surface) is closed during the closing operation of the lid 9. This is for the purpose of moving the latch lever 10 into the case 30 due to the downward stress and overcoming the tip locking claw portion to close the fuel filler opening. As a result, when the lid body 9 is switched to the closed state, the latch lever 10 protrudes greatly to the back surface of the lid body 9 again and securely latches the lid body 9.

  As schematically shown in FIG. 3, the lead wire 7 a and the like of the magnetic sensor 7 are led out of the outer cylinder 14 through the grommet 33. The case 30 is also led out to the opening provided in the outer cylinder 14 through a grommet 34 or the like.

  Next, a mechanism for linking the locking means 11 and the manual push button 12 for releasing the lock will be described with reference to FIG. In this linkage mechanism, a rack 50 that is slidably assembled along the outer surface of the case 30 and is operatively connected to the latch lever 10, and a rotatable first gear that meshes with the lower portion of the rack 50. 51, a second gear 52 rotatable in parallel with the first gear 51 and meshed with each other, a lever 53 integrated with the second gear 52, and above the lever 53, the push button 12 A pressing rod 54 integrated with the lower portion of the lower end of the lower end of the pressing rod 54, a pin 55 which is provided on the lower portion of the pressing rod 54 and in contact with the swinging end of the lever 53, and an upper outer periphery of the pressing rod 54. And a compression coil spring 56 that constantly biases and holds the lower bar 54 in the upper position.

  In this mechanism, when the lid 9 is pushed down while the magnetic sensor 7 is not detected, the push button 12 is pushed down with the fingertip as shown in FIG. Then, the pin 45 pushes down the lever 53, whereby the second gear 52 rotates in the counterclockwise direction, the first gear 51 rotates in the clockwise direction, and the rack 50 holds the latch lever 10 in the case 30. Is slid in the direction of immersion. In addition, although such a manual pushbutton 12 and a cooperation mechanism apply a well-known magnetic latch mechanism, structures other than this may be sufficient. Of course, the push button 12 is covered with an airtight rubber sheet or the like.

(Miscellaneous Oil Prevention Structure) FIG. 6 shows a control configuration of the magnetic sensor 7 and the lock means 11 (solenoid 32) and an example of the control procedure as the opening / closing device 5 and the erroneous oil prevention structure of the present invention. 6A, the magnetic sensor 7 is connected to the input side of the ECU 40 for controlling each part disposed in the vehicle via a lead wire, and the lock means 11 (solenoid 32) is connected via a lead wire (not shown). And connected to the output side of the ECU 40.

  The ECU 40 determines whether or not the magnetic sensor 7 has always detected a magnetic line of force of the chip 17 (magnet 18) (which may be a magnetic pole, the same applies hereinafter) as illustrated in FIG. If it is (Yes in step ST1), the corresponding circuit is switched so that the lock means 11 (solenoid 32) is operated (step ST2). Thereby, the latch lever 10 is immersed in the case 30 against the urging force of the compression coil spring 31, and is switched to the unlocking mode.

  Further, in this structure, an angle sensor 35 that can detect the open state of the lid body 6 by an angle is attached near the rotating shaft portion of the lid body 6, that is, the end of the arm 21, and a lead wire or the like is provided on the input side of the ECU 40 Connected through. Then, in the ECU 40, for example, as shown in FIG. 2 (a), the angle of the lid body 6 from the angle (predetermined opening angle) when the nozzle portion 16 of the oil supply gun 15 is inserted as shown in FIG. 2 (b). When the angle (closing angle) at which the nozzle portion 16 of the gun 15 is removed is detected and it is determined that the set value is satisfied (Yes in step ST3), the lock means 11 (solenoid 32) is again brought into the locking mode. The circuit to be switched is switched (step ST4). Thereafter, the same operation is repeated according to the presence or absence of detection.

  When the above operation is grasped from the refueling operation side, as shown in FIG. 2A, when the tip of the refueling gun 15 (nozzle portion 16) equipped with the tip 17 (magnet 18) is brought close to the refueling port, the lid body The locking of the lock means 11 that locks 9 is released. For this reason, the refueling person applies the tip of the refueling gun 15 (nozzle portion 16) to the lid body 9 as described between ST2 and ST3 in FIG. It is inserted into the fuel pipe 8 while being pushed open against the urging force, and refueling is performed in the inserted state. In this case, the lid body 9 is pushed open without being affected by the pressure in the fuel pipe 8 by the relief valve mechanism described above. Further, in this structure, when the lid body 9 is opened from the closed state by the pulling-out operation of the fuel gun 15, the lock means 11 is again switched to the locking mode through the control of the angle sensor 35 and the ECU 40 as described above.

  By the way, when the lid body 9 is rotated in the closing direction from the open state by the urging force of the winding spring 22, the impact caused by the rapid rotation is avoided by the braking of the damper 24. Disappear.

  Further, in this structure, since the lock means 11 has the manual push button 12 provided in the vicinity of the fuel filler port, the non-detected state of the magnetic sensor 7, that is, the fuel gun 15 has the tip 17 (magnet 18). Even if not, the refueling person can switch the latch lever 10 to the unlocking mode simply by pressing the push button 12 against the spring pressure, and then the nozzle portion 16 of the refueling gun 15 is attached to the lid 9. If pressed, the lid 9 can be pushed open into the fuel pipe 8 and refueled. After the refueling gun 15 is pulled out, the lid body 9 is closed without pressing the push button 12 due to the difference in spring pressure as described above, and in that state, the lid body 9 is locked in the closed state. .

  In the embodiment described above, the tip 17 (magnet 18) as the detected object is provided on the fuel gun 15 side, and the magnetic sensor 7 is provided as the detecting means on the vehicle fuel filler side. The magnetic sensor 7 as the detecting means may be provided on the fuel gun 15 side, and the chip 17 (magnet 18) may be attached to the vehicle fuel filler side. In the latter case, the detection is confirmed by the magnetic sensor 7 on the fueling device side, and the detection is transmitted to the ECU 40 side by a weak radio wave to drive the solenoid 32 to release the lock. Further, in the case of claim 1, various transmitters are used in place of the magnet 18 (chip 17), and detection means corresponding to the transmitter is used in place of the magnetic sensor 7.

  FIG. 7 shows a control example different from FIG. This control feature assumes a mode in which when the oil gun of the different oil type is detected, the lock means 11 is locked to make the oil supply impossible. In this structure, when the lock means 11 opens the outer lid 3, it becomes a lock release mode (steps ST1 and ST2). Further, the magnetic sensor 7 always determines whether or not the magnetic force lines of the chip 17 (magnet 18) are detected. When the magnetic force lines are detected (Yes in step ST3), the lock unit 11 (solenoid 32) is locked. Is switched over to make refueling impossible (step ST5). Conversely, while the outer lid 3 is opened and the magnetic lines of force are not detected, the unlocking mode is maintained (No in step ST3). For this reason, as indicated between ST3 and ST4 in FIG. 7, the refueling person applies the tip of the refueling gun 15 (nozzle portion 16) to the lid 9 and applies the lid 9 to the urging force of the winding spring 22. The oil pipe is inserted into the fuel pipe 8 while being pushed open, and refueling is performed in the inserted state. Further, in this structure, the lid body 9 is changed from the open state to the closed state by the pulling-out operation of the fuel gun 15, and when the lock means 11 closes the outer lid 3, it is switched again to the locking mode (Yes, ST5 in step ST4). )

(Modification) FIG. 8 is a modification of the switchgear described above, FIG. 8 (a) corresponds to FIG. 1, and FIG. 8 (b) is a cross-sectional view taken along line BB in FIG. And the detection range of a magnetic sensor is typically shown using this sectional drawing. That is, the opening / closing apparatus of FIG. 8 is refueled only when the magnetic sensor 7A and the magnet 18A in the chip 17A approach the refueling gun 15 at a normal angle within a preset range with respect to the refueling port as compared with FIG. This is an example configured to detect the lines of magnetic force or magnetic poles of the gun-side magnet 18A. That is, in this example, the magnetic sensor 7A on the fuel filler side (or other detection means) may be mounted on the upper side of the fuel gun side nozzle part 16, that is, on the upper part of the circumference of the nozzle part 16 in use. The normal angle (this angle is determined in advance) that the refueling gun 15 is preferably used as the insertion angle with respect to the refueling port is applied to the magnetic field line or magnetic pole (may be other information) of the magnet 18A (which may be another transmitting device). For example, the magnetic sensor 7A is configured to detect only when the fuel gun 15 approaches at an angle within 30 degrees with respect to the center line N of the fuel filler port. Such a configuration, for example, prevents the locking means 11 from being unlocked even when the fuel gun 15 approaches and deviates from the normal angle with respect to the fuel filler port. Prevents poor lubrication (for example, oil to flow out of the filler port) caused by being inserted, or works as designed to detect when oil is fully filled in the fuel gun. Is possible. As described above, the present invention can be variously modified and developed except for the requirements specified in each claim.
