DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, an embodiment of the invention will be described with reference to the drawings.
FIG. 1 shows a vehicle 1 provided with a vehicle filler opening device 10 according to this embodiment. As shown in FIGS. 1 and 2, a fuel tank 3 is provided in the vehicle body 2 in a fuel lid 3 that is rotatably attached to the vehicle body 2 by an attachment portion having a rotation shaft 3 a and that can be opened and closed. An oil supply port 4 for supplying oil (not shown) is provided, and the oil supply port 4 is closed by screwing a filler cap 5. In the fuel lid 3, an oil filler opening is formed which includes a drive motor 11 and an operating mechanism 12 that opens and closes (including lock) the fuel lid 3 and opens and closes (screws and unscrews) the filler cap 5 based on the driving force of the motor 11. An opener device 10 is provided.

  In the operating mechanism 12 of the filler opening device 10, a base member 16 is connected to the inner side surface 3 b of the fuel lid 3 with a coil spring 15 interposed. The base member 16 is connected to the fuel lid 3 via a connecting member 17. That is, one end of the connecting member 17 is fixed to the base member 16 by the fixing pin 18, and the connecting member 17 is formed with an arcuate guide groove 17 a along the rotation locus of the fuel lid 3 in the fixed state. Yes. A connecting pin 19 provided on the fuel lid 3 is inserted into the guide groove 17a. By the connection by the connection member 17, the relative rotation between the fuel lid 3 and the base member 16 is restricted so as to be within a predetermined range.

  A rotor 20 is rotatably attached to the base member 16, and a wire hooking portion 20 a for hooking a loop-shaped wire 21 is integrally provided on the base member 16 side of the rotor 20. . The wire hooking portion 20a is formed in a disk shape having a smaller diameter than the rotor 20 and the base member 16, and is guided by the rotor 20 and the base member 16 on the outer peripheral surface of the wire hooking portion 20a. A wire 21 is hung. The wire 21 is hooked between the wire hooking portion 20 a of the rotor 20 and the rotating body 22 rotated by the drive motor 11.

  The drive motor 11 is one drive source provided in the filler opening device 10, and operates based on power supply from a battery (not shown) mounted on the vehicle 1. A gear 23 is fixed to the motor rotating shaft 11a of the drive motor 11 so as to rotate integrally, and the gear 23 and the rotating body 22 are engaged with each other. Incidentally, for example, a worm gear mechanism is used for meshing between the gear 23 and the rotating body 22. When the drive motor 11 is driven to rotate, it is decelerated by meshing with the gear 23 to rotate the rotating body 22, and the rotation of the rotating body 22 causes the wire 21 to circulate, whereby the wire hooking portion 20a. That is, the rotor 20 rotates.

  A driving shaft 25 as a driving rotating body is fixed to the central portion of the rotor 20 on the side opposite to the wire hooking portion 20a so as to be integrally rotatable. A sector gear 26 as a second sector gear and a sector gear 27 as a first sector gear are fixed to the front end portion of the drive shaft 25 so as to be integrally rotatable. As shown in FIG. 3, the sector gears 26 and 27 are configured with gear portions 26a and 27a in a 180 ° range, respectively. These sector gears 26 and 27 constitute a switching unit for switching the transmission destination of the driving force.

  In the vicinity of the sector gear 27, a lock driving gear 28 that can mesh with the gear portion 27a is disposed. The lock driving gear 28 is fixed to the base end of the rotary shaft 29, and a lock member 30 that locks the fuel lid 3 is fixed to the tip of the rotary shaft 29. The rotating shaft 29 is supported by a support portion (not shown) connected to the base member 16 so as to be rotatable and immovable in the axial direction. The lock driving gear 28, the rotary shaft 29, and the lock member 30 constitute a lock drive unit that locks and releases the fuel lid 3. Then, the lock member 30 operates so as to be selected between a position (lock position) where the lock member 30 can be locked with the vehicle body locking portion 2a provided in the vehicle body 2 and a position (lock release position) where the lock member 30 cannot be locked, The lock member 30 is arranged at the lock position, so that it can be switched to a locked state in which the opening operation of the fuel lid 3 is prohibited.

  In the vicinity of the sector gear 26, a cap driving gear 31 that can mesh with the gear portion 26a is disposed. The cap driving gear 31 is fixed to an intermediate portion of the rotating shaft 32, and the tip of the rotating shaft 32 is connected to the filler cap 5. The rotary shaft 32 is supported by a support portion (not shown) connected to the base member 16 so as to be rotatable and immovable in the axial direction. The cap driving gear 31 and the rotating shaft 32 constitute a cap driving unit that performs screwing and screwing of the filler cap 5. Then, when the rotating shaft 32 rotates, the filler cap 5 is screwed and screwed into the fuel filler opening 4.

  In the present embodiment, the radius L1 to the gear portion 26a of the sector gear 26 is set larger than the radius L2 to the gear portion 27a of the sector gear 27, while the radius L3 of the cap driving gear 31 is the radius of the lock driving gear 28. It is set smaller than L4. That is, the amount of operation for screwing and screwing of the filler cap 5 is greater than the amount of operation for locking and unlocking the lock member 30, so that for the same amount of rotation of the sector gears 26 and 27 (drive shaft 25), The rotation amount of the cap driving gear 31 is set to be relatively larger than the rotation amount of the lock driving gear 28.

  A screw shaft 33 whose outer peripheral surface is engraved with a screw thread is provided at the base end (fuel lid 3 side) of the rotary shaft 32 so as to be integrally rotatable. It is screwed with a slide member 34 in which a mountain is engraved. The slide member 34 is supported by a support portion (not shown) connected to the base member 16 so as not to rotate and to be movable in the axial direction. The screw shaft 33 and the slide member 34 constitute a lid driving unit that operates the fuel lid 3. When the rotation shaft 32 (screw shaft 33) rotates, a reciprocating linear motion is performed in which the slide member 34 protrudes and retracts toward the fuel lid 3 with respect to the rotation shaft 32, and the slide member 34 protrudes and retracts. The fuel lid 3 is opened and closed.

  Such opening / closing of the fuel lid 3 and screwing / screwing of the filler cap 5 are carried out under the control of the drive motor 11 by the controller 40. More specifically, the controller 40 first performs lid lock and lid lock release in conjunction with the door lock based on the input of a door lock signal indicating door lock and door lock release of the vehicle 1.

  Here, FIG. 2 and FIG. 3A show the locked state of the fuel lid 3, and in this state, the lock member 30 is disposed at a lock position where the lock member 30 can be locked with the vehicle body locking portion 2a. In this case, the rotating shaft 29 to which the lock member 30 is fixed is held so as not to move in the axial direction with respect to the support portion connected to the base member 16, and is thus connected to the base member 16 via the coil spring 15. The fuel lid 3 is in a lid lock state in which the opening operation is prohibited.

  At this time, one end of the gear portion 27a of the sector gear 27 (clockwise direction end portion in FIG. 3A) and the lock driving gear 28 mesh with each other, and the other end of the gear portion 26a of the sector gear 26 (FIG. 3). The end of the counterclockwise direction in (a) and the cap driving gear 31 are engaged with each other. Further, since the drive shaft 25 to which the sector gears 26 and 27 are fixed is drivingly connected to the drive motor 11 via the rotor 20 and the wire 21 or the like, the rotation of the rotary shaft 29 is restricted and the lock member 30 is locked. Maintained in position.

  When the door lock signal is switched to a signal indicating that the door lock is released, the controller 40 drives the drive motor 11 to rotate forward, rotates the rotor 20 via the wire 21, and rotates the drive shaft 25 by 180 °. As a result, the sector gears 26 and 27 rotate 180 ° clockwise to FIGS. 3 (a), 3 (b) and 3 (c). In the rotation range (first rotation range) of the drive shaft 25, the sector gear 27 and the lock driving gear 28 are engaged with each other, and the lock member 30 is disposed at a lock release position where the lock member 30 is not locked with the vehicle body locking portion 2a shown in FIG. Then, the fuel lid 3 is unlocked. In the same rotation range, the meshing between the sector gear 26 and the cap driving gear 31 is released, so that the driving force from the driving shaft 25 is not transmitted to the cap driving gear 31 side, and the filler cap 5 is not screwed off. .

  Incidentally, here, when the door lock signal is switched to a signal indicating the door lock, the controller 40 rotates the drive motor 11 in the reverse direction and rotates the drive shaft 25 by 180 ° in the reverse direction. As a result, the sector gears 26 and 27 are rotated 180 ° counterclockwise until FIGS. 3C, 3B and 3A, and the locking member 30 is moved to FIG. It arrange | positions in the lock position locked with the vehicle body latching | locking part 2a to show, and the fuel lid 3 will be in a locked state again.

  On the other hand, when the fuel lid 3 is in the unlocked state as shown in FIG. 4 and the fuel lid 3 is pressed by the user or the like and slightly closed as shown in FIG. 5, the lid 3 also functions as a command switch. The switch is turned on. Then, a signal indicating that the fuel lid 3 is opened and the filler cap 5 is unscrewed is input to the controller 40 as a command signal (see FIG. 1).

  Then, based on the input of the command signal, the controller 40 drives the drive motor 11 to rotate forward, and further rotates the drive shaft 25 by 180 °. As a result, the sector gears 26 and 27 rotate 180 ° clockwise until FIGS. 3C, 3D, and 3A. In the rotation range (second rotation range) of the drive shaft 25, the sector gear 26 and the cap drive gear 31 are engaged with each other, and the rotation drive force from the drive shaft 25 is transmitted to the rotation shaft 32 as shown in FIG. Then, the screwing of the filler opening 5 of the filler cap 5 is started. In the same rotation range, the meshing between the sector gear 27 and the lock driving gear 28 is released, so that the driving force from the drive shaft 25 is not transmitted to the lock driving gear 28 side, and the lock member 30 is engaged with the vehicle body. It remains retracted to the unlocking position where it does not engage with the portion 2a.

  At the same time, the rotation from the drive shaft 25 is transmitted to the rotation shaft 32, so that the screw shaft 33 rotates together with the rotation shaft 32. Then, the slide member 34 protrudes toward the fuel lid 3 side and presses the inner side surface 3b thereof, and the lid 3 is opened together with the screwing of the filler cap 5 described above. Then, the opening operation of the fuel lid 3 is accompanied by the movement of the base member 16 connected by the connecting member 17, that is, the side of the operating mechanism 12 detaching from the fuel filler 4, and the filler cap 5 is completely screwed off. It is like that. As for the attachment of the drive motor 11, either a configuration in which the drive motor 11 similarly moves with the movement of the operating mechanism 12 or a configuration in which the drive motor 11 is fixed and the wire 21 portion is bent is employed. Then, the fuel lid 3 is opened and the filler cap 5 is unscrewed in this manner, so that fuel can be supplied from the fuel supply port 4 into the fuel tank.

  When refueling is completed, the fuel lid 3 is closed so that the filler cap 5 can be screwed into the refueling port 4, and when the lid 3 is pressed by a user or the like, the command switch of the lid 3 is turned on. Then, the controller 40 drives the drive motor 11 in the reverse direction to rotate the drive shaft 25 by 180 ° in the reverse direction. As a result, the sector gears 26 and 27 rotate 180 ° counterclockwise until FIGS. 3 (a), 3 (d) and 3 (c). By reversing in the rotation range of the drive shaft 25, the rotation shaft 32 is reversed by the meshing of the sector gear 26 and the cap drive gear 31, and the filler cap 5 is screwed into the oil supply port 4 as shown in FIG. . At the same time, the slide member 34 is retracted with the reverse rotation of the rotary shaft 32, and the movement of the operating mechanism 12 toward the fuel filler opening 4 side and the urging force of the coil spring 15 in the closing direction accompanying the screwing of the filler cap 5. The fuel lid 3 is closed.

  When the door lock signal is switched to the signal indicating the door lock, as described above, the controller 40 drives the drive motor 11 in the reverse direction to move the sector gears 26 and 27 to FIGS. 3C, 3B and 3A. Further, the fuel lid 3 is locked by rotating 180 ° counterclockwise and placing the lock member 30 at the lock position shown in FIG. As described above, in this embodiment, the opening / closing including the lock of the fuel lid 3 and the screwing and screwing of the filler cap 5 are performed by driving the single drive motor 11.
