  Corresponding to each protrusion 23, a second protrusion 24 is provided on the outer peripheral portion of the lock shaft 10 on the main body 21 side of the protrusion 23 to be engaged with the inner edge of the square hole 11. The dimension of the second protrusion 24 in the radial direction of the lock shaft 10 is set to be larger than the length of the diagonal line of the square hole 11 of the inner panel 4.

  Details will be described later with reference to FIGS. 6 to 10, but the second protrusion 24 is squared by inserting the protrusion 23 into the groove 16 of the retainer 13 from the diagonal portion 22 of the square hole 11. By contacting the inner edge of the hole 11 and then rotating the main body 21, the edge of the square hole 11 is fitted between the protrusion 23 and the second protrusion 24. The edge of the square hole 11 is held between the portion 23 and the second protrusion 24.

  On the other hand, the main body 21 of the locking device 9 is provided with a main body claw portion 26, and the main body claw portion 26 changes the phase by 90 degrees with respect to the protrusion 23 and the second protrusion 24 and corresponds to the pair of retainer claw portions 15.

The main body claw portion 26 is adapted to be fitted into the retainer claw portion 15 by inserting the protrusion 23 into the groove portion 16 of the retainer 13 and rotating the main body 21.

  By rotating the main body 21, the retainer claw portion 15 and the main body claw portion 26 are fitted, and the protrusion 24 is engaged with the outer edge of the square hole 11 inside the groove portion 16 of the retainer 13, The second protrusion 24 abuts on the inner edge of the square hole 11, and the edge of the square hole 11 is sandwiched between the protrusion 23 and the second protrusion 24. As a result, the locking device 9 is engaged with the outside of the square hole 11 of the inner panel 4 via the protrusion 23, and the locking device 9 is engaged with the retainer 13 on the inner side of the square hole 11 of the inner panel 4. The locking device 9 is fixed to the recess 7.

  A fixing procedure of the lock device 9 will be described with reference to FIGS.

  As shown in FIGS. 6 and 7, from the outside of the inner panel 4, the retainer claw 15 is passed through the notch hole 12 of the square hole 11 and the retainer 13 is inserted. The retainer claw portion 15 is arranged on the inner side of the recess 7 (see FIG. 1). The lock device 9 is inserted into the square hole 11 from the inner side of the inner panel 4. That is, the protrusion 23 is inserted into the diagonal corner 22 (mainly see FIG. 4) of the square hole 11 of the inner panel 4, and the protrusion 23 is inserted into the groove 16 of the retainer 13.

  In this state, the second protrusion 24 contacts the inner edge of the square hole 11, and the position of the diagonal part 22 of the square hole 11 is between the protrusion 23 and the second protrusion 24. (See FIG. 7). As indicated by an arrow in FIG. 6, the main body 21 is rotated counterclockwise in the drawing.

  As shown in FIGS. 8 to 10, the retainer claw portion 15 and the main body claw portion 26 are fitted by rotating the main body 21 (see FIG. 9). Then, the protrusion 23 slides on the groove 16 of the retainer 13 to be engaged with the outer edge of the square hole 11 inside, and the second protrusion 24 contacts the inner edge of the square hole 11. The edge of the square hole 11 is clamped by the protrusion 23 and the second protrusion 24 (see FIG. 10).

  As a result, the locking device 9 is moved to the outside of the square hole 11 of the inner panel 4 by clamping the protrusion 23 and the second protrusion 24 to the edge of the square hole 11 (engagement of the protrusion 23 to the inner panel 4). Can be engaged to the side. At the same time, the locking device 9 can be fitted to the retainer 13 on the inner side of the square hole 11 of the inner panel 4 by the engagement of the retainer claw portion 15 and the main body claw portion 26.

  For this reason, the locking device 9 is engaged with the outside of the square hole 11 of the inner panel 4 through the protrusion 23, and the locking device 9 is engaged with the retainer 13 on the inner side of the square hole 11 of the inner panel 4. The locking device 9 can be fixed to the inner panel 4 of the recess 7.

  The fixing structure of the locking device 9 according to the embodiment of the present invention described above is such that the edge portion of the square hole 11 is sandwiched between the protrusion 23 and the second protrusion 24 at two locations, and the body 21 of the locking device 9 is held on the inner panel 4. Is fixed. At the same time, the retainer claw portion 15 and the main body claw portion 26 are engaged at two locations, and the main body 21 of the lock device 9 is fitted to the retainer 13. For this reason, by rotating the main body 21 of the locking device 9, the locking device 9 can be fixed to the inner panel 4 side at four locations, and the fixing is firmly and reliably without having a complicated structure. Is possible.

  Since the main body 21 is fixed to the inner panel 4 by the protrusion 23 and the second protrusion 24, the load from the main body 21 side can be handled by the inner panel 4, and from the main body 21 side. The load is not concentrated on the retainer 13, and the fixed fixation can be maintained without increasing the size of the retainer 13.

  That is, as shown in FIG. 10, a force acts in the direction of the arrow on the lock shaft 10 of the lock device 9 when the lid 8 (see FIG. 1) is locked / unlocked. Receive load in the direction along. The load received by the main body 21 is transmitted from the protrusion 23 and the second protrusion 24 to the inner panel 4 and does not concentrate on the retainer 13.

  For this reason, the load received when the lid 8 (see FIG. 1) is locked / unlocked is distributed to the inner panel 4, and the locking device 9 can be securely fixed to the recess 7 (see FIG. 1). .

  Therefore, the above-described fixing structure of the locking device 9 according to the embodiment of the present invention has a simple structure and good workability, and the locking device 9 can be fixed to the vehicle body without increasing the size of the retainer 13. Become.

  The configuration of the locking device 9 will be specifically described with reference to FIGS.

  11 is an exploded view showing the internal structure of the lock device 9, FIG. 12 is an external view showing the drive mechanism of the lock shaft 10, FIG. 13 is an external view showing the operation mechanism of the detection switch, and FIG. A side view showing the mechanism, FIG. 15 shows an XV-XV arrow view in FIG. FIGS. 16 to 19 show the operating state of the locking device 9, wherein (a) shows the entire cross section of the fuel filler opening, and (b) shows details of the lid end.

  The locking device 9 will be described with reference to FIGS.

  As shown in FIG. 11, the main body 21 includes a casing 31 and a lid casing 32. A support member 33 that supports the end of the lock shaft 10 is provided on the surface of the main body 21 that faces the inner panel 4, and the protrusion 23 and the second protrusion 24 are provided on the support member 33. Reference numeral 34 in the figure denotes a casing seal.

  As shown in FIGS. 11 and 13, inside the main body 21, there is a lock shaft 10 that moves in the axial direction and prevents the lid 8 from opening and closing when the tip is fitted into the lid 8 (hook portion 51 described later). Is provided. A rack gear 35 is attached to the lock shaft 10, and a compression spring 36 is provided as urging means for urging the lock shaft 10 in the axial direction to fit the lid 8.

  As shown in FIGS. 11 and 12, a pinion gear 37 is provided inside the main body 21, and the pinion gear 37 meshes with the rack gear 35. The pinion gear 37 is integrally provided with a large-diameter rotor gear 38 coaxially. The rotor gear 38 meshes with the output gear 42 of the drive motor 41, and the drive motor 41 drives the output gear 42 and the rotor gear 38 via the output gear 42. The pinion gear 37 is driven.

  Although the driving of the pinion gear 37 by the drive motor 41 will be described in detail later, the engagement with the lid 8 is released from the state where the lock shaft 10 is urged by the compression spring 36 and the tip is engaged with the lid 8. This is implemented when the compression spring 36 is moved against the urging force of the compression spring 36. In other cases, the drive motor 41 and the pinion gear 37 are in a state where power transmission is free.

  As shown in FIGS. 11, 13, and 14, a cam 44 is fixed to the surface of the rotor gear 38, and the cam 44 rotates as the rotor gear 38 rotates. A detection switch 45 is attached to the inside of the main body 21, and the rotation of the rotor gear 38 causes the cam 44 to contact the detection switch 45 to detect the movement state of the lock shaft 10 (open / close state of the lid 8).

  That is, the detection switch 45 outputs an open / close signal for the lid 8. For example, while the detection switch 45 is being pushed by the cam 44, the open / close signal is turned off and the lid 8 is not opened (closed and locked and closed). While the detection switch 45 is not pushed by the cam 44, the open / close signal is turned on and the lid 8 is opened.

  A stopper 46 as a stopper member is attached to a portion corresponding to the upper portion of the rotor gear 38 inside the casing 31. When the lock shaft 10 moves forward by the urging force of the compression spring 36 (when the pinion gear 37 rotates in the first direction), the one end surface 44a of the cam 44 at the rotational position of the rotor gear 38 at the forward end is the stopper 46. The rotation of the rotor gear 38 (the forward movement of the lock shaft 10) is restricted. Further, when the lock shaft 10 is retracted against the urging force of the compression spring 36 (when the pinion gear 37 rotates in the second direction opposite to the first direction), the reverse limit position (limit movement position) ), The other end surface 44b of the cam 44 at the rotational position of the rotor gear 38 comes into contact with the stopper 46, and the rotation of the rotor gear 38 (retraction movement of the lock shaft 10) is restricted.

  The opening / closing state of the lid 8 and the state of the lock shaft 10 (the operating state of the detection switch 45) will be described with reference to FIGS.

  The lid 8 is provided with a hook portion 51 that moves the lock shaft 10 as the door is opened and closed and that engages the tip of the lock shaft 10. That is, the hook portion 51 is provided with an inclined surface portion 52, which is a portion that moves the lock shaft 10 against the urging force of the compression spring 36 by operating the lid 8 to the closed side, and is continuous with the inclined surface portion 52. Thus, a locking step 53 is formed.

  When the lid 8 is operated in the closing direction in a state where the lock shaft 10 is urged by the compression spring 36 and is positioned at the most advanced portion (end position in the axial direction: first position), the inclined surface portion 52 of the hook portion 51 is moved. The tip of the lock shaft 10 comes into contact, and the lock shaft 10 moves backward against the urging force of the compression spring 36. Thereafter, the lock shaft 10 is retracted to the last retracted position at the position of the connecting portion 54 between the inclined surface portion 52 and the locking step portion 53. Further, when the lid 8 is operated in the closing direction, the lock shaft 10 moves forward by the urging force of the compression spring 36 at the position of the locking step portion 53 and is locked before the end position in the axial direction (second position). Engage with the portion 53.

  In a state where the lid 8 is opened, the lock shaft 10 is urged by the compression spring 36 and positioned at the most distal portion as shown by a one-dot chain line in FIG. In this state, as shown in FIG. 14, the rotor gear 38 rotates while the one end surface 44 a of the cam 44 is in contact with the stopper 46, and the detection switch 45 is not pushed by the cam 44. At this time, the open / close signal of the detection switch 45 is turned on, it is detected that the lid 8 is opened, and a signal indicating that the lid 8 is open is output.

  By closing the lid 8, the lock shaft 10 is pushed against the urging force against the compression spring 36 by the inclined surface portion 52 of the hook portion 51, and the rotor gear 38 rotates and the detection switch 45 is pushed by the cam 44. . Further, by closing the lid 8, the state in which the detection switch 45 is pushed by the cam 44 continues, and the lock shaft 10 retreats to the last retracted position at the position of the connecting portion 54 (indicated by a dotted line in FIG. 15).

  Then, with the detection switch 45 being pressed by the cam 44, the lock shaft 10 moves forward by the urging force of the compression spring 36 at the position of the locking step 53 and the locking step just before the axial end. Engage with the portion 53 (shown in solid line in FIG. 15). The lid 8 is locked when the lock shaft 10 is engaged with the engaging step portion 53.

  While the detection switch 45 is pressed by the cam 44, the open / close signal is turned off, and the state where the lid 8 is not opened (closed state) is detected. That is, the rotational phase of the rotor gear 38 (pinion gear 37) in a state where the lock shaft 10 moves against the urging force of the compression spring 36, and the rotor gear 38 in a state where the lock shaft 10 is fitted to the lid 8. In the rotational phase of (pinion gear 37), the cam 44 contacts the detection switch 45, and a signal indicating that the lid 8 is in the closed state is output.

  The locking device 9 described above converts the movement of the lock shaft 10 in the axial direction for locking the lid 8 into the rotation of the cam 44, and detects the open / closed state of the lid 8 by the operation signal of the detection switch 45 by the cam 44. Therefore, it is possible to detect the open / closed state of the lid 8 using a mechanism for locking the lid 8.

  For this reason, even if there is variation in the open / close state of the open / close mechanism due to the assembly tolerance of the lid 8, it is possible to suppress the influence of the variation on the operation range of the detection switch 45, and the open / close state of the lid 8. Can be reliably detected regardless of assembly tolerances.

  Further, when the lock shaft 10 is moved by the urging force of the compression spring 36, the cam 44 and the detection switch 45 are brought into non-contact so that the open signal of the lid 8 is turned on. The cam 44 and the detection switch 45 are brought into contact with each other in the range in which the lock shaft 10 moves against the urging force to turn off the open signal of the lid 8, so that the assembly tolerance of the lid 8 and the operation range of the detection switch 45 can be reduced. Even if there is some variation, the open signal of the lid 8 can be accurately set to the on state.

  That is, by setting the shape of the cam 44 so as to widen the contact range between the cam 44 and the detection switch 45, it is possible to absorb the assembly tolerance and the variation in the operation range in a wide contact range, and the lid 8 is opened. It is possible to accurately detect the signal in the current state.

  Further, since the stopper 46 with which the one end surface 44a of the cam 44 abuts is provided, the rotation of the rotor gear 38 is restricted, and the moving end of the lock shaft 10 on the forward side can be restricted. Then, when the other end surface 44 b of the cam 44 contacts the stopper 46, the rotation of the rotor gear 38 in the reverse direction is restricted, and the moving end of the lock shaft 10 on the backward side can be restricted by one stopper 46. For this reason, even when the lock shaft 10 is moved backward in an emergency or the like, the lock shaft 10 can be prevented from coming off.

  The open / close state of the lid 8 and the operating state of the lock device 9 will be described with reference to FIGS.

  16 shows a state in which the lid 8 is open, FIG. 17 shows a state in which the lid 8 is closed, FIG. 18 shows a state in the middle of the lid 8 closing operation, and FIG. 19 shows a state in which the lid 8 is locked. (A) is a cross section showing the entire structure of the oil filler opening, and (b) shows the details of the end of the lid in (a).

  As shown in FIGS. 16 to 19A, a bracket 61 is fixed to the side edge of the recess 7 of the inner panel 4, and a pivot shaft 62 extending in the vertical direction is rotatably provided on the bracket 61. ing. A hinge arm 63 is rotatably supported on the rotation shaft 62, and the lid 8 is attached to the hinge arm 63. A hook portion 51 is attached to the end portion of the lid 8 on the opposite side of the rotation shaft 62.

  A spring 64 is provided between the bracket 61 and the hinge arm 63, and the hinge arm 63 (lid 8) is biased to the opening side by the spring 64. A square hole 11 is provided in the recess 7 of the inner panel 4, a retainer 13 is provided outside the square hole 11, and the lock device 9 is fixed from the inside of the square hole 11. The distal end portion of the lock shaft 10 of the lock device 9 faces the concave portion 7 from the square hole 11, and when the lid 8 is closed, the distal end of the lock shaft 10 is engaged with the engagement step portion 53 of the hook portion 51.

  As shown in FIGS. 16A and 16B, when the lid 8 is open, the lock shaft 10 is moved to the forward end (first position) by the urging force of the compression spring 36. In this state, as described above, the cam 44 and the detection switch 45 are brought into a non-contact state, and the lid 8 open signal is turned on. That is, it is detected that the lid 8 is in an open state.

  Based on the information that the open signal of the lid 8 is turned on, for example, disabling the opening / closing of the sliding door, disabling the operation of the engine or motor, turning on the indicator or the lighting device inside the recess 7 Controls such as controlling lighting are performed.

  As shown in FIGS. 17A and 17B, when the lid 8 is rotated to the closed side against the urging force of the spring 64, the lock shaft 10 is compressed along the inclined surface portion 52 of the hook portion 51. Retreats against the urging force of. Further, as shown in FIGS. 18A and 18B, when the lid 8 is rotated to the closed side, the lock shaft 10 resists the urging force of the compression spring 36 at the position of the connecting portion 54 of the hook portion 51. Move backward to the last retracted position.

  When the lock shaft 10 moves backward against the biasing force of the compression spring 36, the cam 44 is rotated by the rotation of the rotor gear 38, the cam 44 contacts the detection switch 45, and the opening signal of the lid 8 is turned off. Is done. That is, it is detected that the lid 8 is in a closed state.

  As shown in FIGS. 19A and 19B, when the lid 8 is closed, the lock shaft 10 moves from the connecting portion 54 of the hook portion 51 to the locking step portion 53, and the position of the locking step portion 53 is reached. Thus, the lock shaft 10 moves forward by the urging force of the compression spring 36 and engages with the locking step portion 53 in front of the axial end position (first position) (second position). The lid 8 is locked when the lock shaft 10 is engaged with the engaging step portion 53. In this state, as described above, the contact state between the cam 44 and the detection switch 45 is maintained, and the open signal of the lid 8 is turned off. That is, it is detected that the lid 8 is in a closed state (locked state).

  When the lid 8 is opened by refueling or the like, the drive motor 41 is driven, and the lock shaft 10 is moved backward against the biasing force of the compression spring 36 via the output gear 42, the rotor gear 38, the pinion gear 37 and the rack gear 35. When the lock shaft 10 moves backward to the position where the engagement with the locking step portion 53 is released, the hinge arm 63 (lid 8) is biased to the open side by the biasing force of the spring 64. As a result, the lid 8 is opened, the lock shaft 10 is moved to the forward end by the urging force of the compression spring 36, the cam 44 and the detection switch 45 are brought into a non-contact state, and the opening signal of the lid 8 is turned on.

  Therefore, it is possible to detect the open / closed state of the lid 8 using a mechanism for locking the lid 8 of the fuel filler opening 6, and there is a variation in the open / closed state of the open / close mechanism due to the assembly tolerance of the lid 8. However, it is possible to suppress the influence of the variation on the operation range of the detection switch 45, and the open / closed state of the lid 8 can be reliably detected regardless of the assembly tolerance.

  In the above-described embodiment, the lid 8 of the fuel supply port 6 is described as an example. However, when the supply port having the charging port is applied, the position of the charging port is an arbitrary place of the vehicle. The position to be provided is not limited to the rear side, but may be various positions depending on the position of the charging port, such as the front side, the rear end, and the front end.

  Further, the configuration of the lock device 9 is not limited to the configuration of the above-described embodiment. For example, the lock device 9 is manually locked via a push-pull wire or the like by a configuration in which the detection switch 45 is not provided or an operation from the driver's seat. It is possible to apply a lock device configured to be released.

  The present invention can be used in the industrial field of a locking device for locking a lid for an energy supply port of a vehicle.
