  By the way, in the fuel lid locking device proposed in the above-mentioned Patent Document 1, even when the output rod is moved forward with the fuel supply opening being opened as described above, the fuel lid is closed. The output rod moves backward to close the fuel supply opening, that is, the fuel lid can be fully closed, but in order to maintain such a fully closed state, after unlocking the door lock mechanism once There is a problem that it is inconvenient because it is necessary to perform the locking operation again to move the output rod to advance.

  Further, although not explicitly disclosed in the above-described Patent Document 1, a fuel lid lock device having a push lifter is known. The push lifter is one that alternately repeats the protruding state and the retracted state by being pressed by the passage swing after the closing operation of the fuel lid, and allows the fuel lid to be fully closed in the retracted state, In the protruding state, the fuel lid is restricted from being fully closed.

  In a fuel lid locking device provided with such a push lifter, if the fuel lid is closed, but the pressure on the push lifter is insufficient and the fuel lid is fully closed without being pulled in, the door When the lock mechanism is unlocked, the output rod moves backward and the fuel lid opens unexpectedly due to the urging force of the push lifter, which may cause the fuel supply opening to open. There was also the problem of being.

  In view of the above circumstances, the present invention provides a fuel lid lock device capable of preventing a fuel lid from opening unexpectedly and opening a fuel supply opening while improving convenience. With the goal.

  In order to achieve the above object, a fuel lid locking device according to claim 1 of the present invention includes a fuel lid that is swingably disposed so as to open and close a fuel supply opening of a vehicle body, and the fuel lid that performs a closing operation. By pressing by passing through a fully closed position that fully closes the fuel supply opening, the protruding state and the retracted state are alternately repeated, and in the retracted state, the fuel lid is fully closed. On the other hand, the push lifter that restricts the fuel lid from being fully closed in the projecting state and the actuator is driven so as to be able to move forward and backward along its extending direction and moved forward. In this case, the fuel lid can be kept in the fully closed state, whereas when the fuel lid moves backward, the fuel lid In the fuel lid lock device comprising an output rod that allows the lid to open the door, the output rod moves forward and backward along its own central axis direction by driving the actuator, and the rod base of the rod base An adapter that is arranged so as to be capable of moving forward and backward along the central axis direction of the rod base body so as to cover the tip, and is urged to move forward by biasing means interposed between the rod base body and the adapter. The fuel lid, when abutting against the adapter of the output rod that has moved forward by performing a door closing operation, the abutting portion for retreating the adapter against the urging force of the urging means; A load that restricts the movement of the adapter in a locked state with the protrusion formed on the adapter that has been retracted and moved in contact with the contact portion by the closing operation. And a stepped portion that abuts on the tip portion of the adapter that has moved forward again after being unlocked from the overlapped portion by passing rocking after the door closing operation and restricts the adapter moving forward, and When the push lifter is retracted and positioned at the fully closed position by the swinging movement after the closing operation, the overlapped portion and the stepped portion are formed in a continuous manner. An engagement protrusion having an engagement hole portion through which the adapter that moves forward after the contact state is released is provided.

  The fuel lid lock device according to claim 2 of the present invention is the fuel lid lock device according to claim 1, wherein the adapter rotates by a predetermined angle around the central axis of the rod base when the retraction movement is performed. On the other hand, the forward movement rotates in the opposite direction to the retracting movement around the central axis of the rod base, and the engagement hole portion and the overlapping portion have the fuel lid fully closed. When positioned at a position, the output rod is allowed to retract while maintaining the posture of the adapter inserted through the engagement hole.

  According to the fuel lid lock device of the present invention, the output rod is moved in the central axis direction of the rod base body so as to cover the tip of the rod base body that moves forward and backward along its own central axis direction by driving the actuator. And an adapter that is urged to move forward by urging means interposed between the rod base and the engagement protrusion of the fuel lid is moved forward by closing the door. An abutment portion that retracts the adapter against the biasing force of the biasing means when it abuts against the adapter of the moved output rod, and an adapter that is retracted and moved against the abutment portion by the closing operation The protruding portion formed in the engagement portion is in a locked state, the overlapping portion that restricts the advance movement of the adapter, and the locked state with the overlapping portion is released by the passing swing after the door closing operation, and the advanced portion moves again. A step part that contacts the tip part of the adapter and that regulates the movement of the adapter is formed in a continuous manner between the overlapping part and the step part, and the push lifter is retracted by the passing swing after the closing operation. When it is in the fully closed position, it has an engagement hole portion through which the adapter that moves forward is released after the contact state with the stepped portion is released. Even when the output rod is moved forward with the supply opening opened, the adapter constituting the output rod can be caused to enter the engagement hole of the engagement protrusion by closing the fuel lid. The fuel lid can be held in a fully closed state. Moreover, since the push lifter is retracted by the swinging movement after the fuel lid is closed, there is no possibility that the fuel lid opens unexpectedly and the fuel supply opening is opened. Therefore, it is possible to prevent the fuel lid from opening unexpectedly and opening the fuel supply opening while improving convenience.

  Further, according to the fuel lid lock device of the present invention, when the adapter is retracted, the adapter rotates around a central axis of the rod base by a predetermined angle, whereas when the adapter moves forward, the adapter is centered on the rod base. When the fuel lid is located at the fully closed position, the engaging hole and the overlapping portion maintain the posture of the adapter inserted through the engaging hole. Since the output rod is allowed to retract, the output rod can be easily retracted from the state where the fuel lid is fully closed, thereby avoiding complicated operations. There is an effect that the operation reliability can be improved.

  Exemplary embodiments of a fuel lid lock device according to the present invention will be described below in detail with reference to the accompanying drawings.

  FIG. 1 is a schematic view schematically showing a fuel lid lock device according to an embodiment of the present invention, and a part thereof is shown in cross section. The fuel lid locking device exemplified here includes a fuel lid 10, a push lifter 20, and an output rod 30.

  The fuel lid 10 is for opening and closing the fuel supply opening 2 provided in the left rear region of the vehicle main body 1, and is arranged in such a manner that it can swing around the axis of the hinge shaft 11. When opening the fuel supply opening 2, the fuel lid 10 opens the door to the left around the axis of the hinge shaft 11. On the other hand, when closing the fuel supply opening 2, the fuel lid 10 is hinged. The door is closed to the right around the axis of the shaft 11.

  The push lifter 20 is disposed on the right side of the vehicle with respect to the fuel lid 10. The push lifter 20 is repeatedly pressed between a protruding state and a retracted state by being pressed by a swinging passage after the fuel lid 10 is closed. More specifically, a protrusion that protrudes with respect to the housing (not shown) when its own operating rod (not shown) comes into contact with and presses against the inner surface of the fuel lid 10 by swinging after the fuel lid 10 is closed. The state and the drawn-in state are alternately repeated. The fuel lid 10 is allowed to be fully closed in a state where the operating rod is retracted relative to the housing, that is, in the retracted state. Here, the fully closed state refers to a state in which the fuel lid 10 closes the fuel supply opening 2 and the outer surface of the fuel lid 10 forms substantially the same surface as the outer surface around the fuel supply opening 2. On the other hand, in a state where the operating rod protrudes from the housing, that is, in the protruding state, the fuel lid 10 is restricted from being fully closed. More specifically, the tip end portion of the operating rod presses the inner surface of the fuel lid 10 to bring the fuel lid 10 into a posture in which the door is slightly opened.

  2 and 3 schematically show the output rod 30 shown in FIG. 1, respectively. FIG. 2 is a schematic view showing the case viewed from the right side of the vehicle, and FIG. 3 is a view seen from above the vehicle. It is a schematic diagram which shows. As shown in FIGS. 2 and 3, the output rod 30 is disposed on the right side of the vehicle main body 1 and on the rear side of the fuel supply opening 2, and includes a rod base 31 and an adapter. 32.

  The rod base 31 extends along the front-rear direction of the vehicle body 1, and the base end is curved and connected to the connecting portion 331 of the actuator 33. The actuator 33 is configured by incorporating a motor or the like inside the housing, and is driven in conjunction with a case where a door lock mechanism (not shown) is locked and unlocked. The actuator 33 moves the rod base 31 toward the front of the vehicle when the door lock mechanism is locked, while the rod base 31 is directed toward the rear of the vehicle when the door lock mechanism is unlocked. It is to be moved. As described above, when the rod base 31 moves toward the front of the vehicle, the output rod 30 moves forward toward the front of the vehicle, while when the rod base 31 moves toward the rear of the vehicle, the output rod 30 is moved. Will move backward toward the rear of the vehicle.

  As shown in FIGS. 4A and 4B, the rod base 31 is provided with a plurality of (two in the illustrated example) protrusions 311 at the tip.

  The adapter 32 is formed from a resin material, for example, and is disposed in a manner covering the tip of the rod base 31. As shown in FIGS. 5A and 5B in an enlarged manner, the adapter 32 has an inclined surface 321 formed at the tip portion, and a plurality (two in the illustrated example) of protrusions 322. Projected. The adapter 32 is formed with a long hole 323 on the rear side of the vehicle with respect to the portion where the protrusion 322 is formed. The long hole 323 allows the protrusion 311 of the rod base body 31 to enter, and is inclined from the long hole 3231 extending in the vehicle front-rear direction and the rear end of the long hole 3231. And an inclined hole portion 3232 that extends.

  Such an adapter 32 is formed by passing a projection 311 of the rod base 31 through the elongated hole 3231 and the inclined hole 3232 with a spring member (not shown) as an urging means interposed therebetween. The base 31 is disposed so as to cover the tip. The adapter 32 is disposed so as to be capable of moving forward and backward along the extending direction of the rod base 31, and is always urged so as to move forward toward the front of the vehicle by a spring member. At this time, the protruding portion 311 of the rod base 31 is located at the rear end of the inclined hole portion 3232, and the advance movement of the adapter 32 is restricted. Here, the extending direction and the extending length of the inclined hole portion 3232 will be described in detail later, but the distal end portion of the adapter 32 is pressed and the adapter 32 resists the urging force of the spring member to the rear of the vehicle. The adapter 32 is adjusted so that the adapter 32 can be rotated about 45 ° around the central axis thereof, that is, the central axis of the rod base 31 when retreating toward the center.

  As will be described in detail later, the adapter 32 is in a posture in which the protrusion 322 is rotated about 45 ° around the central axis of the rod base 31 when the adapter 32 is urged by the spring member to move forward. Is. Further, the inclined surface 321 shown in FIG. 5B is configured by a curved surface that does not change the projected shape even when the adapter 32 rotates.

  An engagement protrusion 40 projects from the vehicle rear side end of the fuel lid 10, that is, the inner surface of the swing side end. FIG. 6 shows the main part of the fuel lid 10 shown in FIG. 1, that is, the engaging protrusion 40. FIG. 6A is a cross-sectional view showing the engaging protrusion as viewed from above the vehicle. FIG. 6B is an explanatory diagram showing a case where the state of FIG. 6A is viewed from the rear of the vehicle. The engagement protrusion 40 illustrated here includes a contact portion 41 and an engagement hole 43. 6A, for convenience of explanation, it is assumed that the fuel lid 10 is in a state in which the fuel supply opening 2 is closed, the left side in the figure is the vehicle front side, and the right side in the figure is the right side. Will be described as the vehicle rear side.

  As shown in FIG. 6A, the contact portion 41 has a shape projected from the top of the vehicle, and relates to a portion where the inclined surface 321 of the adapter 32 can be contacted by opening and closing the fuel lid 10. An inclining portion is formed at the projecting end of the mating projection 40 and gradually inclines toward the hinge shaft 11 side (vehicle front side) of the fuel lid 10 toward the projecting end.

  An engagement hole 42 extending from the middle of the contact portion 41 toward the fuel lid 10 side (the vehicle left side) is formed. The engagement hole 42 has a width that allows entry of a portion of the adapter 32 excluding the protrusion 322. Further, a curved portion R is formed at the intersection between the contact portion 41 of the engagement protrusion 40 and the engagement hole 42 so that the adapter 32 does not get caught when the adapter 32 enters.

  The engagement hole 43 is a hole that is provided in a manner continuous with the engagement hole 42 and penetrates the engagement protrusion 40 along the front-rear direction of the vehicle. The engagement hole 43 has a width that allows the adapter 32 constituting the output rod 30 to enter.

  On the projecting end side of the engaging protrusion 40 with respect to the engaging hole 43, an overlapping portion 44 narrower than the engaging hole 43 is provided. The width of the overlapping portion 44 is large enough to allow the portion of the tip portion of the adapter 32 excluding the protruding portion 322 to enter. That is, the width of the overlapping portion 44 will be described in detail later, but the adapter 32 in the state of progressing movement, that is, the projection 32 322 passes through the adapter 32 in a posture rotated about 45 ° around the central axis of the rod base 31. It has an allowable size.

  Further, the wall surface on the fuel lid 10 side (the vehicle left side) constituting the engagement hole 43 protrudes to the vehicle left side in the middle, that is, on the vehicle front side from the portion where the overlapping portion 44 is provided. A step 45 is provided. That is, the engagement hole portion 43 is formed in a manner that is continuous between the overlapping portion 44 and the step portion 45.

  In the fuel lid lock device having the above-described configuration, the fuel lid 10 can be held in the fully closed state as follows.

  First, the case where the fuel lid 10 is held in the fully closed state in a state where the fuel lid 10 performs the door closing operation and is located at the fully closed position to close the fuel supply opening 2 will be described.

  In such a state, when the actuator 33 is driven by the locking operation of the door lock, the rod base 31 constituting the output rod 30 moves toward the front of the vehicle. As the rod base 31 moves, the adapter 32 arranged to cover the tip of the rod base 31 also moves toward the front of the vehicle integrally with the rod base 31. That is, the output rod 30 moves forward.

  When the output rod 30 advances and moves in this manner, the adapter 32 that is the tip portion of the output rod 30 is inserted through the engagement hole 43 in the engagement protrusion 40 of the fuel lid 10, whereby the entire fuel lid 10 is moved. The closed state can be maintained.

  Next, in a state where the fuel lid 10 is opened and the fuel supply opening 2 is opened, and the actuator 33 is driven and the output rod 30 is moved forward by the locking operation of the door lock, the fuel lid is moved. A case where 10 is held in a fully closed state will be described.

  When the fuel lid 10 is closed in such a state, the contact portion 41 of the engaging projection 40 provided on the fuel lid 10 is output as shown in FIGS. 7 and 8A and 8B. The rod 30 abuts on the tip portion of the adapter 32. Here, since the abutting portion 41 is formed with an inclined portion, and the inclined surface 321 is also formed at the tip portion of the adapter 32, the adapter 32 is retracted to the vehicle rear side against the urging force of the spring member. Moving. Thus, when the adapter 32 performs the retreating movement, the protrusion 311 provided on the rod base 31 relatively moves along the inclined hole portion 3232 in the elongated hole 323 of the adapter 32. As shown in (b), the adapter 32 rotates about 45 ° (forward rotation) around the central axis of the rod base 31 with respect to the rod base 31.

  The adapter 32 rotated by a predetermined angle (about 45 °) while being retracted by the closing operation of the fuel lid 10 enters the engaging hole 42 of the engaging protrusion 40, and according to the closing operation, the engaging hole 40 42 is moved relatively. At this time, the protruding portion 322 of the adapter 32 moves while abutting against the abutting portion 41 of the engaging projection 40, so that the tip portion of the adapter 32 is separated from the engaging hole 42.

  As shown in FIG. 9, the push lifter 20 contacts the inner surface of the fuel lid 10 that performs the door closing operation. In this case, as shown in FIGS. 10A and 10B, the protrusion 322 formed at the tip of the adapter 32 comes into contact with the overlapping portion 44 of the engagement protrusion 40 to be in a locked state. . That is, the overlapping portion 44 of the engaging protrusion 40 is engaged with the protruding portion 322 formed on the adapter 32 that has been retracted by being brought into contact with the abutting portion 41 by the door closing operation, and the progression of the adapter 32 is increased. Restricts movement.

  As shown in FIG. 11, when the fuel lid 10 abutting against the push lifter 20 passes and swings through the fully closed position that closes the fuel supply opening 2, the push abutted against the inner surface of the fuel lid 10. The lifter 20 is pressed into a retracted state. Further, the passing state swings the engagement state between the overlapping portion 44 and the adapter 32, and the adapter 32 is urged by the spring member as shown in FIGS. 12A and 12B. Then, the vehicle moves forward toward the front of the vehicle, and a part thereof enters the engagement hole 43.

  The adapter 32 that has partially entered the engagement hole 43 advances with the tip portion contacting the step 45 of the engagement protrusion 40 as shown in FIGS. 13 and 14A and 14B. Movement is restricted. That is, the step 45 of the engaging protrusion 40 abuts on the tip end portion of the adapter 32 which is released from the locked state with the overlapping portion 44 by the passing swing after the door closing operation and moves forward again. Restricts progressive movement.

  As shown in FIG. 15, when the fuel lid 10 that has passed and swayed is slightly swayed to the left side of the vehicle and then located at the fully closed position where the fuel supply opening 2 is closed, As shown in FIGS. 16A and 16B, the contact state between the adapter 32 and the stepped portion 45 is released. Then, the adapter 32 is urged by the spring member and moves forward. During such advancement and movement, the protrusion 311 of the rod base 31 moves relative to the inclined hole 3232 of the long hole 323, so that the adapter 32 rotates about 45 ° around the central axis of the rod base 31 (reverse rotation). To do. As the adapter 32 moves forward in this manner, the engagement hole 43 of the engagement protrusion 40 is inserted, whereby the fully closed state of the fuel lid 10 can be maintained.

  By the way, the adapter 32 that has moved forward is in a posture in which the protruding portion 322 disposed on the adapter 32 is rotated about 45 ° around the central axis of the rod base 31 and can pass through the width of the overlapping portion 44. Yes. Therefore, when the actuator 33 is driven by the unlocking operation of the door lock from the state where the fuel lid 10 is kept in the fully closed state, the output rod 30 can move backward while maintaining the posture of the adapter 32. That is, the engagement hole 43 and the overlapping portion 44 have a shape that allows the adapter 32 inserted through the engagement hole 43 to retreat.

  As described above, according to the fuel lid lock device of the present embodiment, the output rod 30 includes the rod base 31 that moves forward and backward along the direction of its own central axis by driving the actuator 33, and the tip of the rod base 31. An adapter 32 that is arranged so as to be able to move forward and backward along the central axis direction of the rod base 31 and is biased to move forward by a spring member interposed between the rod base 31 and When the engaging protrusion 40 of the fuel lid 10 contacts the adapter 32 of the output rod 30 that has moved forward by performing a door closing operation, the engaging protrusion 40 retracts against the biasing force of the spring member. When the adapter 32 is in a locked state with the protrusion 322 formed on the adapter 32 that has been retracted and moved in contact with the contact portion 41 by the door closing operation, the adapter 32 advances. The movement of the adapter 32 is restricted by abutting against the distal end portion of the adapter 32 that has been moved forward again after the locked state of the overlapping section 44 that restricts movement and the passing movement after the closing operation is released. An engaging hole 43 through which the adapter 32 that moves forward when the push-lifter 20 is in the retracted state and is located at the fully closed position is released from the contact state with the step 45. Therefore, even when the fuel lid 10 is opened and the fuel supply opening 2 is opened, the door lock is locked and the output rod 30 is moved forward. By closing the door, the adapter 32 constituting the output rod 30 can enter the engagement hole 43 of the engagement protrusion 40, and the door lock is unlocked again without locking the door. Can hold Eruriddo 10 is fully closed. Moreover, since the push lifter 20 is retracted by the swinging movement of the fuel lid 10 after the closing operation, there is no possibility that the fuel lid 10 opens unexpectedly and the fuel supply opening 2 is opened. Accordingly, it is possible to prevent the fuel lid 10 from opening unexpectedly and opening the fuel supply opening 2 while improving convenience.

  According to the fuel lid locking device described above, after the fuel lid 10 is moved from the swinging position after the closing operation to the fully closed position, the overlapping portion 44 is engaged with the protruding portion 322 of the adapter 32, and then the step is stopped. Since the portion 45 is brought into contact with the tip portion of the adapter 32, the adapter 32 is not inserted into the engagement hole 43. Therefore, the engagement hole 43 does not need to be large enough to allow the fuel lid 10 to pass through and swing after the adapter is inserted through the adapter 32, whereby the adapter 32 is inserted into the engagement hole 43. It is possible to make the size necessary and sufficient for the adapter 32 and to reduce the amount of play with the adapter 32. Further, according to the fuel lid locking device, the axis of the adapter 32 before the adapter 32 is inserted through the engaging hole 43, that is, before the outer surface of the fuel lid 10 forms substantially the same surface as the outer surface around the fuel supply opening 2. When the direction and the longitudinal direction of the engagement hole 43 are inclined, the tip end portion of the adapter 32 is formed by the overlapping portion 44 of the engagement hole 43 wider than the engagement hole 43 by the width of the step 45. The inclination can be absorbed by being located in the vicinity. Therefore, the width of the engagement hole 43 can be made large enough to allow the adapter 32 to be inserted, and the backlash with the adapter 32 can be made small.

  Further, according to the fuel lid lock device, the above-described effects are achieved by the structural contrivance between the output rod 30 and the engaging protrusion 40, and an expensive electronic device or the like is not used, so that the cost can be increased. It can be suppressed, and can be applied to conventional vehicles, and has excellent versatility.

  Further, according to the fuel lid lock device, when the adapter 32 is retracted, the adapter 32 is rotated forward by a predetermined angle (about 45 °) around the central axis of the rod base 31, while when the adapter 32 is advanced, The engagement hole portion 43 and the overlapping portion 44 are inserted into the engagement hole portion 43 when the fuel lid 10 is located at the fully closed position. Since the output rod 30 has a shape that allows the adapter rod 32 to be retracted while maintaining the posture of the adapter 32, the output rod 30 can be easily retracted from the state where the fuel lid 10 is fully closed, Thereby, a complicated operation can be avoided and the operation reliability can be improved.
