  TECHNICAL FIELD The present invention relates to a fuel lid lock device, and more particularly to a fuel lid lock device that holds a fuel lid arranged to be able to open and close a fuel supply opening of a vehicle body in a locked state and switches between a locked state and an unlocked state. Is.

  Conventionally, as this type of fuel lid locking device, there is known a device that holds the fuel lid in a locked state by engaging the tip of the output rod with the engagement hole of the fuel lid by advancing and retracting the output rod by the sector gear (for example, , See Patent Document 1).

  FIG. 25 is a diagram illustrating the configuration of the fuel lid lock device disclosed in Patent Document 1 in a locked state. In the fuel lid lock device 100, a motor 102, a sector gear 104, and an output rod 105 are arranged in a lower case 101. An upper case (not shown) is attached to the lower case 101.

  The motor 102 has a worm 103 attached to a rotating shaft 102b extending from the main body 102a. The sector gear 104 has a sector part 104a formed on one side and a lever part 104b formed on the other side. The sector gear 104 has an insertion hole 104c between the sector portion 104a and the lever portion 104b. The sector portion 104a has a gear 104d that meshes with the worm 103 on the outer periphery formed in an arc shape. The lever portion 104 b has an engagement shaft 104 e protruding from the upper surface facing the output rod 105 toward the output rod 105. The shaft portion 101a provided in the lower case 101 is inserted through the insertion hole 104c. For this reason, the sector gear 104 rotates around the shaft portion 101a.

  The output rod 105 has a sliding shaft portion 105a and a sector connecting shaft portion 105b each formed of a square bar, and a round rod shaft portion 105d is formed at an end portion via a flange 105c.

  The sliding shaft portion 105a is a portion that slides in the lower case 101 along the longitudinal direction of the output rod 105. An inclined surface 105e is formed at the tip, and a damper 106 is attached substantially in the middle. The damper 106 abuts against the inner surface of the lower case 101, thereby restricting the protruding amount of the output rod 105 from the lower case 101 so that the tip of the sliding shaft portion 105 a protrudes by a predetermined amount to the outside of the lower case 101.

  The sector connecting shaft portion 105b is a square bar having a width wider than that of the sliding shaft portion 105a, and a long hole 105f is formed at the center for engaging the engaging shaft 104e of the sector gear 104 along the longitudinal direction. The round rod shaft portion 105d is provided with an output rod 105 at all times so that the tip of the sliding shaft portion 105a protrudes outside the lower case 101 by disposing the return spring 107 between the inner wall of the lower case 101 and the flange 105c. It is fast.

  As shown in FIG. 25, when the sector gear 104 is at the rotation position L1 indicated by the alternate long and short dash line, the fuel lid lock device 100 has the tip of the sliding shaft portion 105a of the output rod 105 at the lock-on position (lock position) Lon. is there. At this time, if the fuel lid is closed, the sliding shaft portion 105a is locked in the locking hole 120a of the lock piece 120 provided in the fuel lid, so that the fuel lid is locked and cannot be opened.

  In the state where the tip of the sliding shaft portion 105a of the output rod 105 shown in FIG. 25 is at the lock-on position (lock position) Lon, power is supplied to the motor 102 from the power connector inserted into the connector portion 101b of the lower case 101. When supplied, in the fuel lid lock device 100, the sector gear 104 rotates around the shaft portion 101a by the gear 104d engaged with the worm 103. FIG. 26 is a diagram illustrating the state after the rotation, and the sector gear 104 rotates to the rotation position L2 indicated by the alternate long and short dash line. As a result, the tip of the sliding shaft portion 105a of the output rod 105 moves backward to the lock-off position (unlock position) Loff. As a result, the fuel lid lock device 100 is switched to the unlocked state in which the engagement between the sliding shaft portion 105a and the engagement hole 120a of the lock piece 120 is released, and the fuel lid can be opened. At this time, electric power is supplied to the motor 102 for a predetermined time.

  When the fuel lid locking device 100 is unlocked and the power supply to the motor 102 is stopped, the output rod 105 reverses the sector gear 104 and the worm 103 by the urging force of the return spring 107, and the lock-on position shown in FIG. (Lock position) Return to Lon. As a result, when the output lid 105 is disposed at the lock position in a state where the fuel lid is opened, the fuel lid locking device 100 closes the opened fuel lid so that the lock piece 120 provided on the fuel lid has the inclined surface 105e at the tip. The output rod 105 is moved to the left in FIG.

  For this reason, when the tip of the sliding shaft portion 105 a coincides with the locking hole 120 a of the lock piece 120, the output rod 105 is pushed out by the urging force of the return spring 107. As a result, as shown in FIG. 25, the fuel lid locking device of Patent Document 1 returns the output rod 105 to the lock-on position (lock position) Lon, and the tip of the sliding shaft portion 105a is the locking hole of the lock piece 120. The state is switched to the locked state engaged with 120a, and the fuel lid is locked.

  Here, the side wall 6i serves as a start positioning portion for determining the movement start position of the slider 7 by contacting the slider 7 placed on the placement portion 6f. The flange 6k serves as a positioning portion that determines the retracted position Pb of the slider 7 that slides by engaging with the pair of guide rails 6g. The bent portion 6e protrudes into the vehicle compartment and is used as an emergency manual operation unit that manually switches the fuel lid lock device 1 from the locked state to the unlocked state.

  Next, the slider 7 placed on the placement portion 6f will be described with reference to FIGS. FIG. 11 is a plan view of the slider. FIG. 12 is a right side view of the slider. FIG. 13 is a bottom view of the slider. 14 is a cross-sectional view taken along the line C3-C3 in FIG. 11 of the slider placed on the placement portion of the slider with gear.

  As shown in FIGS. 11 to 14, the slider 7 as a slide member has a boss portion 7a formed on the upper surface of one side in the longitudinal direction of a plate formed in a substantially rectangular shape, and a rod hole 7b in the center of the boss portion 7a. Is formed. A pair of guide rails 7c that respectively engage with the guide rails 6g of the mounting portion 6f are formed in the width direction on the lower surface facing the boss portion 7a. The guide rail 7c is formed with protrusions that maintain a constant interval between the guide rail 6g and the guide rail 6g. A slit 7d is formed in the longitudinal direction on the other side of the slider 7 facing the boss 7a.

  As shown in FIG. 4, a coil spring 8 is disposed between the slider 7 and the mounting portion 6 f. In the coil spring 8, when the slider 7 moves along the pair of guide rails 6g, the direction of the urging force along the moving direction is reversed during the movement. The coil spring 8 has one end (upper end) 8a locked in the back of the slit 7d (see FIG. 5) and the other end (lower end) 8b locked in a locking hole 6m provided in the mounting portion 6f. (Refer to FIG. 6), it is disposed between the slider 7 and the mounting portion 6f.

  The locking rod 9 is supported by the slider 7 and moves in the front-rear direction of the vehicle VH as the motor 3 is driven. 4 to 6, the locking rod 9 rises diagonally forward from the base 9a supported by the slider 7, the bent portion 9b bent at a right angle to the base 9a, and the bent portion 9b. The inclined portion 9c is bent in this manner, and the extending portion 9d is provided in parallel with the bent portion 9b so as to be continuous with the inclined portion 9c. In the unlocked state of the fuel lid lock device 1, the locking rod 9 is disposed at the unlock position Pul on the rear side of the vehicle with respect to the bracket BK, as shown in FIGS.

  Here, FIG. 15 is a cross-sectional view taken along line C4-C4 when the slider 7 is placed on the placement portion 6f of the slider 6 with gear shown in FIG. As shown in FIG. 15, the base 9 a is supported by the slider 7 with the rod holder 10 and washers 11, 12 interposed between the locking rod 9 and the rod hole 7 b.

  As shown in FIG. 15, the rod holder 10 is inserted into the rod hole 7b of the slider 7 and has an insertion portion 10a whose lower end is locked around the base portion 9a and a flange portion 10b formed at the upper end of the insertion portion 10a. And a gripping portion 10c that is continuous from the flange portion 10b outward in the radial direction of the rod hole 7b and grips the outer periphery of the locking rod 9 from three directions. The washer 11 is disposed above the rod hole 7b, and the washer 12 is disposed below the rod hole 7b.

  Here, when the fuel lid lock device 1 is attached to the inner panel of the vehicle main body BD, the locking rod 9 supports the middle of the extending portion 9d by the holder Hd attached to the vehicle main body BD, as shown in FIGS. As a result, the movement direction is regulated so as to move in the front-rear direction of the vehicle VH, and the positioning is performed with respect to the bracket BK or the engagement hole H of the bracket BK. For this reason, when the opened fuel lid FL is closed, the bracket BK moves from the left front side to the left rear side of the vehicle main body BD in a substantially horizontal plane as indicated by an arrow A in FIG.

  Here, the length of the base portion 9a of the locking rod 9 is set to a length at which the lower end of the base portion 9a is located between the flange 6k and the lower surface of the placement portion 6f. When such a length is set, when the locking rod 9 moves along the pair of guide rails 6g together with the slider 7 on the mounting portion 6f, the locking rod 9 moves until the base portion 9a contacts the flange 6k. At this time, when the movement of the slider 7 along the guide rail 6g is restricted by the contact between the base 9a of the locking rod 9 and the flange 6k, the slider 7 moves backward between the lock position Pl and the unlock position Pul. It arrange | positions in the position Pb.

  The fuel lid lock device 1 is configured as described above. When the locking rod 9 is disposed at the unlock position shown in FIGS. 4 to 6, the engagement hole H provided in the bracket BK and the extending portion are provided. Since the engagement with the tip of 9d is released, the fuel lid FL can be opened.

  Next, switching from the unlocked state to the locked state of the fuel lid lock device 1 will be described with reference to FIGS. FIG. 16 is a front view of the fuel lid lock device in the middle of switching from the unlocked state to the locked state. FIG. 17 is a plan view of the fuel lid lock device in the middle of switching from the unlocked state to the locked state. FIG. 18 is a front view of the fuel lid lock device that is switched from the unlocked state to the locked state. FIG. 19 is a plan view of the fuel lid lock device switched from the unlocked state to the locked state.

  First, when the door is locked by operating the door lock mechanism, the fuel lid lock device 1 is operated in conjunction with the door lock operation, and the lock rod 9 is moved to the lock position Pl by the drive of the motor 3 to enter the locked state. Can be switched. That is, the motor 3 is driven by the control signal output from the control means of the vehicle VH, and the geared slider 6 slides leftward from the case 2 as shown in FIGS. Thereby, the locking rod 9 advances forward of the vehicle, and the tip of the extending portion 9d approaches the bracket BK.

  When the geared slider 6 slides by a predetermined stroke set in advance, the drive of the motor 3 is stopped, and as shown in FIGS. 18 and 19, the tip of the extending portion 9d moves to the lock position Pl, and the engagement of the bracket BK. The fuel lid locking device 1 is switched to the locked state by engaging with the joint hole H. For this reason, the fuel lid locking device 1 locks the fuel lid FL when the tip of the locking rod 9 engages with the engagement hole H of the bracket BK. Accordingly, when the fuel lid lock device 1 is switched to the locked state, the fuel lid FL cannot be opened. In the fuel lid lock device 1, when the door lock mechanism is unlocked and the door is unlocked, the locked state is switched to the unlocked state by the reverse operation.

  By the way, as described above, the fuel lid locking device 1 opens the fuel lid FL after moving the locking rod 9 to the unlocked position and switching to the unlocked state, for example, for refueling work to the vehicle VH. In this state, when the door is locked by operating the door lock mechanism, the lock rod 9 is moved to the lock position Pl.

  In the present embodiment, when the fuel lid FL is closed in such a situation, the bracket BK pushes the locking rod 9 so that the slider 7 is retracted on the mounting portion 6f to the retracted position Pb. As a result, the fuel lid FL can be opened again. The operation of the fuel lid lock device 1 at this time will be described below with reference to FIGS.

  FIG. 20 is a front view of the fuel lid lock device in the middle of the slider 7 moving backward on the mounting portion 6f of the geared slider 6 toward the case 2 side. FIG. 21 is a plan view of the fuel lid lock device 1 in the middle of the slider 7 moving backward on the mounting portion 6f of the slider 6 with gear to the case 2 side. FIG. 22 is a front view of the fuel lid lock device 1 when the slider 7 moves on the placement portion 6f of the geared slider 6 and stops at the retracted position Pb. FIG. 23 is a plan view of the fuel lid lock device 1 when the slider 7 moves on the placement portion 6f of the geared slider 6 and stops at the retracted position Pb. 20 and 21 show the fuel lid lock device 1 at a position where the direction of the urging force of the coil spring 8 is reversed.

  When the locking rod 9 is switched to the locked position Pl with the fuel lid FL open, when the fuel lid FL is closed, the bracket BK that moves in a substantially horizontal plane while drawing an arc from the left front of the vehicle body BD is shown in FIG. As shown in FIGS. 20 and 21, the tip of the locking rod 9 is pressed. As a result, the slider 7 is pressed through the locking rod 9, and the slider 7 moves backward on the mounting portion 6f of the geared slider 6 to the case 2 side. At this time, the slider 7 moves to the case 2 side on the mounting portion 6f of the geared slider 6 while resisting the biasing force of the coil spring 8 and the sliding resistance between the guide rail 6g and the guide rail 7c. Since the resistance force between the geared slider 6 and the motor 3 is set to be larger, the mounting portion 6f does not move.

  Then, when the fuel lid FL is fully closed, the pressing of the tip of the locking rod 9 by the bracket BK is stopped, and the slider 7 is at the retracted position Pb closest to the case 2 side, as shown in FIGS. Stop. At this time, the locking rod 9 receives the urging force of the coil spring 8 reversed by the slide of the slider 7, but as shown in FIG. 15, the base 9a abuts against the side surface of the flange 6k to stop the slider 7. ing. In this case, the position of the tip of the locking rod 9 at the retracted position Pb of the slider 7 is the retracted position Pe between the lock position Pl and the unlock position Pul. The fuel lid locking device 1 is set such that the moving distance between the locking position Pl and the unlocking position Pul of the locking rod 9 is longer than the moving distance between the lock position Pl and the retracted position Pe. Yes.

  As a result, the retracted position Pe is located closer to the lock position Pl than the unlock position Pul. Therefore, during the normal unlocking operation by the motor 3, the locking rod 9 is placed between the unlock position Pul and the lock position Pl. By moving the fuel lid FL, the fuel lid FL can be surely locked and unlocked. When the fuel rod FL is opened and the locking rod 9 is switched to the lock position Pl, when the fuel lid FL is closed, the tip of the locking rod 9 and the bracket BK is surely disengaged.

  At this time, in the fuel lid lock device 1, no urging force is applied to the locking rod 9. For this reason, the locking rod 9 merely retracts the slider 7 by the pressing force acting from the bracket BK by closing the fuel lid FL. And even if the front-end | tip of the locking rod 9 moves to the retracted position Pe, the locking rod 9 does not engage with the engagement hole H of the bracket BK. For this reason, when it becomes necessary to open the fuel lid FL again, the fuel lid FL can be opened without being obstructed by the locking rod 9 by operating the fuel lid FL in the opening direction. It can also be closed.

  In this way, the fuel lid locking device 1 can easily open and close the fuel lid FL without driving the motor 3 even when the fuel lid is switched to the locked state despite the fuel lid being opened.

  Further, when the front end of the locking rod 9 is moved to the retracted position Pe and the fuel lid FL is opened and closed, a passenger who has finished refueling releases the door lock mechanism to unlock the door, and then enters the vehicle VH. The control means outputs a control signal to switch the fuel lid lock device 1 with the locking rod 9 in the retracted position Pe to the unlocked state. At this time, in the fuel lid locking device 1, when the motor 3 is driven by the control signal input from the control means and the geared slider 6 starts moving rightward in FIG. After the right side comes into contact with the left side of the case 2, sliding is started to the left against the biasing force of the coil spring 8 while being guided by the pair of guide rails 6 g.

  However, the fuel lid lock device 1 is set so that the movement distance between the lock position Pl and the unlock position Pul of the locking rod 9 is longer than the movement distance between the lock position Pl and the retreat position Pe. Yes. A coil spring 8 is disposed between the slider 7 and the mounting portion 6f so that when the slider 7 moves along the pair of guide rails 6g, the direction of the urging force along the moving direction is reversed during the movement. Has been. For this reason, in the fuel lid lock device 1, the direction of the urging force acting on the slider 7 from the coil spring 8 is reversed from right to left at the position shown in FIG.

  As a result, the position of the locking rod 9 can be reliably switched from the retracted position Pe to the unlocked position Pul, and a gap is formed between the bracket BK and the tip of the extending portion 9d of the locking rod 9 as shown in FIG. Is formed. Accordingly, when the position of the locking rod 9 is switched from the retracted position Pe to the unlocked position Pul, the fuel lid locking device 1 smoothly moves the fuel lid FL without contacting the bracket BK and the tip of the extending portion 9d of the locking rod 9. Can be opened and closed. At this time, the door lock mechanism is unlocked and the fuel lid device 1 is in the unlocked state. Thus, if the door lock mechanism is locked, the fuel lid lock device 1 is also switched to the locked state, so that the door lock mechanism can be used in the same manner as usual, and the door lock mechanism is easy to use.

  The locking rod is not limited to the shape of the locking rod 9 of the embodiment as long as the locking rod moves forward and backward along the axial direction by the driving force transmitted from the motor 3. For example, in the locking rod 9, the length of the bent portion 9b may be shorter than that of the embodiment, and the angle of the inclined portion 9c may be smaller than that of the embodiment.

  As described above, the fuel lid lock device of the present invention is suitable for easily opening and closing the fuel lid without driving the electric actuator when the locking rod is switched to the lock position with the fuel lid opened.
