Description

  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. 22 is a diagram illustrating a configuration of a locked fuel lid lock device disclosed in Patent Document 1. As illustrated in FIG. 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 in which the output rod 105 slides in the longitudinal direction with respect to the lower case 101, and an inclined surface 105e is formed at the tip, and a damper 106 is attached at substantially the center in the longitudinal direction. . The damper 106 abuts against the inner surface of the lower case 101, thereby restricting the amount of protrusion of the sliding shaft portion 105a from the lower case 101.

  The sector connecting shaft portion 105b is a rectangular bar having a width wider than that of the sliding shaft portion 105a, and a long hole 105f that engages with the engaging shaft 104e of the sector gear 104 is formed along the longitudinal direction substantially at the center in the longitudinal direction. ing. A return spring 107 is disposed between the inner wall of the lower case 101 of the round bar shaft portion 105d and the flange 105c. Thereby, the output rod 105 is always urged so that the tip of the sliding shaft portion 105a protrudes to the outside of the lower case 101.

  As shown in FIG. 22, when the line passing through the rotation center of the sector gear 104 is at the 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. 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.

  Then, in a state where the tip of the sliding shaft portion 105a of the output rod 105 shown in FIG. 22 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. 23 is a diagram illustrating a state after the fuel lid lock device 100 is rotated (unlocked state). In FIG. 23, the line passing through the rotation center of the sector gear 104 rotates to the rotation position L2 indicated by the alternate long and short dash line, so that the tip of the sliding shaft portion 105a of the output rod 105 moves backward to the lock-off position (unlock position) Loff. is doing. 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 tip of the sliding shaft part 105a moves backward to the lock-off position (unlock position) Loff and the power supply to the motor 102 stops, the output rod 105 reverses the sector gear 104 and the worm 103 by the urging force of the return spring 107. However, it returns to the lock-on position (lock position) Lon shown in FIG. As a result, the output rod 105 returns to the locked position with the fuel lid opened. Therefore, when the opened fuel lid is closed, in the fuel lid locking device 100, the lock piece 120 provided on the fuel lid contacts the inclined surface 105e at the tip, and 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. 22, the fuel lid locking device 100 is configured such that the output rod 105 returns to the lock-on position (lock position) Lon and the tip of the sliding shaft portion 105 a is engaged with the locking hole 120 a of the lock piece 120. Together, it switches to the locked state and the fuel lid is locked.

JP 2001-65215 A

  By the way, the fuel lid locking device 100 can close the fuel lid even if the output rod 105 is switched to the lock position in a state where the fuel lid is opened as described above, but the fuel lid is locked. For this reason, when it becomes necessary to open the fuel lid again, the fuel lid locking device 100 has to perform an unlocking operation to energize the motor 102 again and move the output rod 105 to the lock-off position (unlock position) Loff. Therefore, there is a problem that the operation is complicated. Further, the fuel lid lock device 100 has to continue energization of the motor 102 in order to hold the output rod 105 at the lock-off position Loff, and there is a problem that the motor 102 and the battery are consumed. .

  The present invention has been made in view of the above, and an object of the present invention is to provide a fuel lid lock device that can easily open and close the fuel lid without driving the electric actuator even when the fuel lid is opened and switched to the locked state. And

  In order to solve the above-described problems and achieve the object, the fuel lid lock device of the present invention moves with the drive of the electric actuator with respect to the fuel lid that can be opened and closed outside the fuel filler arranged in the vehicle body. A fuel lid locking device that locks or unlocks according to the tip position of the locking rod to be moved and can shift to a locked state regardless of the open / closed state of the fuel lid, wherein the fuel lid is locked or unlocked by the electric actuator.

Move linearly, and move the holding part relative to the driven member along the direction of movement of the driven member. Connecting means for holding the holding portion in a stationary state with respect to the driven member at an operating position or a retracted position along a moving direction of the driven member, and the operating rod is locked by the locking rod. Alternatively, when the fuel lid is closed when the fuel lid is locked and the fuel lid is closed when the fuel lid is in a locked state, the retracting position is a position where the locking rod is unlocked by a force received from the fuel lid. It is a position where it is moved and the locked state is released.

  In the fuel lid lock device according to the present invention, in the above invention, the connecting means is formed at an end portion of the driven member facing the holding portion, and the operating position and the retracted position are provided on both sides of the narrow portion. It has a long hole arranged, and the narrow part is a connecting part elastically deformed with the movement of the locking rod.

  In the fuel lid locking device of the present invention, in the above invention, the driven member has a driven connecting portion at an end of the driven member facing the holding portion, and the connecting means is the holding member. A connecting case formed with a long hole that engages with the portion, the connecting case protruding into the long hole in the middle of the long hole, and elastically moving the holding part to either the operating position or the retracted position. It has the leaf | plate spring to hold | maintain automatically.

  In the fuel lid lock device of the present invention, in the above-described invention, the fuel lid lock device includes a housing in which the electric actuator is accommodated, and the locking rod projects from the coupling means to the housing side at a position adjacent to the holding portion. And the stopper portion is in contact with the housing in the unlocked state of the fuel lid lock device, and the stopper portion is in a state where the holding portion of the locking rod is held in the retracted position. When the locking rod is moved to a position corresponding to the unlocked state by the driven member, the end of the stopper portion comes into contact with the housing, so that the holding portion is moved from the retracted position to the operating position. It is made to move to.

  In the fuel lid lock device of the present invention, in the above invention, the movement distance of the locking rod from the position corresponding to the locked state to the retracted position where the locked state is released is a position corresponding to the locked state. The moving distance of the locking rod from the position to the position corresponding to the unlocked state is smaller.

  According to the present invention, since the driven member and the holding portion of the locking rod are connected and the locking rod is movably held in either the operating position or the retracted position, the fuel lid is opened. Even if the locking rod is switched to the locked position, if the fuel lid is closed, the fuel lid moves the locking rod back to the retracted position, and the fuel lid is not locked by the locking rod. For this reason, there exists an effect that a fuel lid can be opened and closed easily, without driving an electric actuator.

As shown in FIGS. 4 and 5, the fuel lid lock device 1 includes a case 2, a motor 3, a reduction gear 5, a geared slider 6, and a locking rod 9. In the fuel lid lock device 1, the operation of the motor 3 is controlled by a control means (not shown) of the vehicle VH so as to be interlocked with the locking / unlocking operation of the door lock mechanism.

  As shown in FIG. 5, the case 2 accommodates a motor 3, an intermediate portion between the reduction gear 5 and the geared slider 6. The case 2 is provided with a bracket (not shown) for installation on the vehicle body BD and a connector housing (not shown) for connecting a power supply connector.

  The motor 3 as an electric actuator is operated by electric power supplied via a power connector connected to the connector housing, and is interlocked with the locking / unlocking operation of the door lock mechanism under the control of the control means of the vehicle VH. The geared slider 6 is driven to switch the position of the locking rod 9 between a lock position Pl for locking the fuel lid FL and an unlock position Pul for unlocking the fuel lid FL. The motor 3 has a worm 4 attached to a rotating shaft.

  As shown in FIG. 5, the reduction gear 5 is engaged with the gear portion 6 b of the worm 4 and the geared slider 6, and reduces the rotational speed of the motor 3 and transmits it to the gear portion 6 b of the geared slider 6.

  As shown in FIG. 5, the geared slider 6 as the driven member is driven by the motor 3 and slides with respect to the case 2 in the left-right direction indicated by the arrow A2. The geared slider 6 is provided with a gear part 6b on one side via a shaft part 6a and a connecting part 6c as connecting means on the other side. As shown in FIG. 6, the connecting portion 6 c connects the geared slider 6 and the proximal end side of the locking rod 9. Accordingly, the geared slider 6 transmits the driving force of the motor 3 to the locking rod 9 via the connecting portion 6c. The connecting portion 6c has a long hole 6d with which the proximal end side of the locking rod 9 engages, and the middle of the long hole 6d protrudes from both sides in the width direction to the long hole 6d so that the locking rod 9 is in either the operating position Pw or the retracted position Pe. It has the narrow part 6e hold | maintained on one side. In each narrow portion 6e, a cavity 6f is disposed between the narrow portion 6e and the outer wall.

  As shown in FIGS. 4 and 5, the locking rod 9 includes a stopper portion 9a and a holding portion 9b that are disposed on the proximal end side, and a bent portion 9c, an extension portion 9d, and an inclined portion 9e that are subsequently disposed. And an engaging portion 9f. The stopper portion 9a is disposed on the base end side in the axial direction in parallel with the long hole 6d of the connecting portion 6c, and protrudes from the connecting portion 6c to the case 2 side. The holding portion 9b is disposed adjacent to the stopper portion 9a, is bent at a right angle with respect to the stopper portion 9a, and is held by the connecting portion 6c. The bent portion 9c is bent at a right angle with respect to the holding portion 9b and arranged parallel to the stopper portion 9a. After protruding from the connecting portion 6c to the bracket BK side, the bent portion 9c is further bent 90 degrees and arranged parallel to the holding portion 9b. The The extension portion 9d is further bent at a right angle from the bent portion 9c and disposed on the extension line of the connecting portion 6c. The inclined portion 9e is inclined so as to rise obliquely forward from the extended portion 9d. The engaging portion 9f is horizontally disposed adjacent to the inclined portion 9e and has a tip engaged with an engaging hole H of the bracket BK provided on the back surface of the fuel lid FL. 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, when the fuel lid locking device 1 is attached to the inner panel of the vehicle main body BD, the locking rod 9 supports the middle of the engaging portion 9f 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. Therefore, 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 A1 in FIG.

  The fuel lid lock device 1 is configured as described above. When the locking rod 9 is disposed at the unlock position Pul shown in FIGS. 4 and 5, the fuel lid lock device 1 is engaged with the engagement hole H provided in the bracket BK. Since the tip of the portion 9f is not engaged, the fuel lid FL can be opened.

  FIG. 7 is a front view showing the fuel lid lock device 1 switched from the unlocked state to the locked state with the locking rod 9 as a cross section. FIG. 8 is a plan view of the fuel lid lock device 1 switched from the unlocked state to the locked state.

  In the unlocked state of the fuel lid lock device 1, when the door lock mechanism is locked and the door is locked, the lock rod 9 is moved to the lock position Pl by the drive of the motor 3 in conjunction with the door lock operation, and is brought into 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 by a preset stroke. Thereby, as shown in FIGS. 7 and 8, the fuel lid locking device 1 is switched to the locked state by moving the distal end of the engaging portion 9f to the locking position Pl and engaging with the engaging hole H.

  As a result, the fuel lid locking device 1 is locked with the fuel lid FL. Therefore, if the fuel lid locking device 1 is switched to the locked state with the fuel lid FL closed, 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, in the fuel lid lock device 1, for example, for refueling work to the vehicle VH, the locking rod 9 is moved to the unlock position Pul and switched to the unlocked state, and then the fuel lid FL is opened. 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 holding portion 9b is retracted from the operating position Pw to the retracted position Pe, and the fuel lid FL is opened again. Will be able to. The operation of the fuel lid locking device 1 at this time will be described below with reference to FIGS.

  FIG. 9 is a front view showing the fuel lid lock device 1 in a state where the holding portion 9b of the locking rod 9 is retracted from the connecting portion 6c of the geared slider 6 to an intermediate position between the operating position Pw and the retracted position Pe, with the locking rod 9 as a cross section. FIG. FIG. 10 is a plan view of the fuel lid lock device 1 in a state in which the holding portion 9b of the locking rod 9 has retracted the connecting portion 6c of the geared slider 6 to an intermediate position between the operating position Pw and the retracted position Pe. FIG. 11 is a front view showing the fuel lid locking device 1 with the locking rod 9 in cross section when the holding portion 9b of the locking rod 9 retracts the connecting portion 6c of the geared slider 6 to the retracted position Pe. FIG. 12 is a plan view of the fuel lid lock device 1 when the locking rod 9 retracts the connecting portion 6c of the geared slider 6 to the retracted position Pe.

  When the locking rod 9 is switched to the locked position Pl in a state where the fuel lid FL is open, when the fuel lid FL is closed, as shown in FIGS. 9 and 10, an arc is drawn from the left front of the vehicle main body BD in a substantially horizontal plane. The bracket BK that moves is pressed against the tip of the engaging portion 9 f of the locking rod 9. As a result, the locking rod 9 is guided and moved by the connecting portion 6c of the holder Hd and the slider 6 with gear, and the holding portion 9b of the locking rod 9 retracts the connecting portion 6c to the case 2 side. For this reason, in the connecting portion 6c of the geared slider 6, the holding portion 9b of the locking rod 9 is elastically deformed so as to push and widen the narrowed portion 6e, and the connecting portion of the geared slider 6 is expanded while expanding the central portion of the long hole 6d. The inside of the long hole 6d formed in the part 6c is moved to an intermediate position between the operating position Pw and the retracted position Pe.

  At this time, the holding portion 9b moves between the operating position Pw and the retracted position Pe while elastically deforming so as to push the narrow portion 6e, but the geared slider 6 and the motor 3 are more than the force required for this movement. It is set so that the resistance force between is larger. As a result, in the fuel lid lock device 1, the connecting portion 6c of the slider 6 with gear does not move.

  When the fuel lid FL reaches the fully closed position, the pressing of the distal end of the locking rod 9 by the bracket BK is released, and the locking rod 9 has a holding portion 9b in the long hole 6d as shown in FIGS. It is held at the retracted position Pe. At this time, since the shape of the elastically deformed narrow portion 6e is restored by the movement of the holding portion 9b, the holding portion 9b is held at the retracted position Pe. However, since the bracket BK only pushes the tip and retracts the locking rod 9, the tip of the engaging portion 9f of 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.

  As described above, 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 FL is switched to the locked state with the fuel lid FL open.

  FIG. 13 is a diagram illustrating the position of the stopper portion of the locking rod 9 in the unlocked state, the locked state, and the retracted position in the fuel lid lock device 1. In FIG. 13, P1 is the position of the stopper portion 9a in the unlocked state, P2 is the position of the stopper portion 9a in the locked state, and P3 is the position of the stopper portion 9a in the retracted position Pe. Therefore, in the figure, the distance between the position P1 and the position P2 is equal to the moving distance of the locking rod 9 between the lock position Pl and the unlock position Pul, and the distance between the position P2 and the position P3 is the lock position Pl. And the moving distance of the tip of the locking rod 9 between the retracted position Pe. Accordingly, the fuel lid locking device 1 is set so 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 positioned closer to the lock position Pl than to the unlock position Pul. Therefore, during the unlocking operation by the normal 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.

  Also, when the locking rod 9 is moved to the retracted position Pe and the fuel lid FL is opened and closed, or when the occupant who has finished refueling operates the door lock mechanism to unlock the door and then enters the vehicle VH, etc. 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. The operation of the connecting portion 6c of the geared slider 6 of the fuel lid lock device 1 in this case will be described below with reference to FIGS.

  FIG. 14 is a plan view of the fuel lid lock device 1 showing a state where the stopper portion 9 a of the locking rod 9 is in contact with the case 2. FIG. 15 is a plan view of the fuel lid lock device 1 showing a state in which the holding portion 9b of the locking rod 9 has moved to the center of the connecting portion 6c. FIG. 16 is a plan view of the fuel lid lock device 1 showing a state in which the holding portion 9b of the locking rod 9 has moved to the operating position Pw of the connecting portion 6c.

  First, the control means of the vehicle VH outputs a control signal to drive the motor 3. Then, the fuel lid lock device 1 starts moving the geared slider 6 together with the locking rod 9 from the position shown in FIG. 12 to the right. As shown in FIG. Contact the left side. At this time, the holding portion 9b of the locking rod 9 is held at the retracted position Pe of the connecting portion 6c.

  When the stopper portion 9a comes into contact with the case 2, the movement of the locking rod 9 is restricted. For this reason, with the movement of the slider 6 with gear, the locking rod 9 is elastically deformed so that the holding portion 9b spreads the narrow portion 6e, and moves in the long hole 6d of the connecting portion 6c. As a result, the holding portion 9b of the locking rod 9 moves to an intermediate position between the retracted position Pe and the operating position Pw in the long hole 6d of the connecting portion 6c, as shown in FIG.

  When the movement of the slider 6 with gear is completed, as shown in FIG. 16, it moves to the operating position Pw of the connecting portion 6c, and the fuel lid lock device 1 is switched to the unlocked state.

  At this time, the door lock mechanism is unlocked, and the fuel lid lock 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 connecting portion 6c of the slider 6 with gear is provided with narrow portions 6e on both sides in the width direction in the middle of the long hole 6d in the first embodiment. However, if the narrowed portion 6e can elastically hold the locking rod 9 in either the operating position Pw or the retracted position Pe, as shown in FIG. It may be provided only.
