Description

TECHNICAL FIELD The present invention relates to a locking device.

Patent Document 1 discloses a locking device for a lid that releasably closes a power supply port of an electric vehicle. This locking device includes a locking member that is movable between a locking position where the lid is locked and an unlocking position where the lid is unlocked, and an electric actuation mechanism that includes a motor that moves the locking member. Further, the locking device includes a manual lock release mechanism that moves the locking member from the locked position to the unlocked position when the locking member cannot be moved by the operating mechanism due to a failure of the motor or the like. The lock release mechanism includes a wire with an operating section disposed inside the vehicle (for example, in the trunk), and a flat section having a long hole for connecting to the locking member is provided at the tip of the wire. The locking member is formed with a claw-like projection that is inserted into the elongated hole. Even if the locking member moves between the locked position and the unlocked position during normal times, the claw-like protrusion only moves inside the elongated hole, so movement of the wire due to movement of the locking member can be suppressed.

Embodiments of the present invention will be described below with reference to the drawings.

Referring to FIG. 1, a lid opening/closing device 10 including a locking device 40 according to an embodiment of the present invention is attached to a side panel (panel) 1 of an automobile. The side panel 1 is provided with a receiving port 2 penetrating in the vehicle width direction Y.

The X direction shown in the drawing is the vehicle length direction of the vehicle, the Y direction is the vehicle width direction, and the Z direction is the vehicle height direction of the vehicle. In each figure, the direction indicated by the arrow in the X direction is the front side, and the direction opposite to the arrow is the rear side. The direction indicated by the Y-direction arrow is the inside (inside) of the vehicle, and the direction opposite to the arrow is the outside (outside) of the vehicle. The direction indicated by the Z-direction arrow is the upper side, and the direction opposite to the arrow is the lower side.

Referring to FIG. 1, the lid opening/closing device 10 includes a power supply connector (receiving section) 15 to which a charging plug (not shown) is connected. However, the receiving section may be for replenishing either liquid fuel such as gasoline and light oil, or gaseous fuel such as hydrogen or LP gas.

Referring to FIGS. 4 and 5, the lid opening/closing device 10 can open the base 20 attached to the inside of the side panel 1 (see FIG. 1) in the vehicle width direction Y and the intake port 2 (see FIG. 1). A movable lid (object) 30 is provided. The lid 30 includes an arm 32 whose pivot portion 36 on one end side is pivotally supported by the base 20, and is rotatable between a closed position shown in FIG. 3 and an open position shown in FIG. 2. The arm 32 includes an arm main body 33 made up of a first arm part 34 and a second arm part 35, and a spindle 37 forming a part of a pivoting part 36.

The locking device 40 locks the arm 32 so that it cannot move when the lid 30 is in the closed position shown in FIG. The lock device 40 includes a lock pin (lock member) 41, a torsion spring 46, a cover (guide member) 28, an electric drive mechanism 50, and a manually operated lock release member 65. The lock release member 65 includes a lever 70 and a transmission member 80. The transmission member 80 includes a wire 81 and a connected member 82 .

Referring to FIGS. 4 and 5, the drive mechanism 50 includes a motor (drive source) 51 and an input cam (cam member) 52 having a cam surface 53a. A cover 28 is arranged between the motor 51 and the input cam 52. Further, a lever 70 and a part of a transmission member 80 are arranged between the motor 51 and the cover 28. The drive mechanism 50 of this embodiment includes a differential mechanism 60 that transmits a driving force to the spindle 37 to open and close the lid 30. The differential mechanism 60 includes a recess 39 provided on the spindle 37 and a protrusion 54 provided on the input cam 52. When rotating the lid 30 from the closed position to the open position, the differential mechanism 60 delays the rotation of the spindle 37 with respect to the start of rotation of the lock pin 41.

Referring to FIGS. 13 to 16, the lock pin 41 is moved from the lock position to the unlock position by the drive mechanism 50 or the lock release member 65, and from the unlock position to the lock position by the torsion spring 46. When the lock pin 41 is in the locked position, the lid 30 is locked so that it cannot be moved. When the lock pin 41 is in the unlocked position, the lid 30 is unlocked and the lid 30 is unlocked to be movable.

When the lock pin 41 is rotated to the unlock position by the opening operation of the drive mechanism 50, the driving force of the motor 51 is transmitted to the spindle 37 via the input cam 52 and the differential mechanism 60 (see FIG. 5), so that the arm 32 rotates to the extended position where it protrudes outside the side panel 1 shown in FIG. Thereby, the lid 30 assumes a posture (open position) in which the intake port 2 is opened, as shown in FIG. Furthermore, the closing operation of the drive mechanism 50 causes the arm 32 to rotate to the retracted position in which it is retracted into the side panel 1 shown in FIG. As a result, the lid 30 assumes a posture (closed position) in which the intake port 2 is closed, as shown in FIG. 3, and the lock pin 41 is rotated to the lock position by the biasing force of the torsion spring 46.

The lock release member 65 is used in an emergency when the drive mechanism 50 cannot operate the lock pin 41 due to a failure of the motor 51 or the like. In other words, the lock release member 65 is not used when the drive mechanism 50 is normal and not in trouble. Referring to FIG. 4, the lock release member 65 is attached to rotate the input cam 52 similarly to the motor 51. Specifically, a lever 70 to which a wire 81 is connected via a connected member 82 is attached to the input cam 52, and by pulling the wire 81, the input cam 52 is rotated. That is, by using the lever 70 and the wire 81, a driving force is generated manually instead of the motor 51, and the lock pin 41 is rotated from the lock position to the unlock position. As a result, manual rotation of the lid 30 from the closed position shown in FIG. 3 to the open position shown in FIG. 2 is possible.

In this manner, the locking device 40 in this embodiment switches between the unlocked state and the locked state using the drive mechanism 50 and the torsion spring 46 during normal operation. Further, in an emergency, the locking device 40 is switched from the locked state to the unlocked state by manually rotating the input cam 52 using the unlocking member 65.

The base 20, cover 28, arm 32, lock pin 41, torsion spring 46, drive mechanism 50, differential mechanism 60, and lock release member 65 will be specifically described below.

Referring to FIGS. 1 and 4, the base 20 includes a base body 21 that closes the intake port 2, and a bearing portion 24 that pivotally supports the arm 32.

The base body 21 is provided with a mounting portion 22 to which the power supply connector 15 is attached. A sealing member 23 is attached to the outer peripheral edge of the base body 21 to provide a watertight seal between the base body 21 and the lid 30. The base body 21 is further provided with an insertion hole 21a through which the arm 32 is inserted so as to be movable back and forth, and an opening 21b in which a switch (not shown) is disposed so as to be located inside the intake port 2 when viewed from the vehicle width direction Y.

A lock pin 41, a torsion spring 46, and an input cam 52 are housed between the cover 28 and the upper surface of the end wall 25. A mounting piece 28a for mounting the motor 51 is provided protruding from the upper surface side of the cover 28. Further, the cover 28 is provided with a through hole 28b for connecting the external motor 51 and the internal input cam 52. Further, the cover 28 is provided with an arrangement structure for the lever 70 and a wiring structure for the wire 81, and the specific structures thereof will be described in detail later.

Referring to FIGS. 1 to 3, the arm 32 of the lid 30 is disposed extending from the inside to the outside of the base 20 in the vehicle width direction Y through the insertion hole 21a. Referring to FIG. 5, the arm 32 includes a pivot portion 36 that is pivotally supported by the bearing portion 24, and rotates integrally with the pivot portion 36. More specifically, the arm 32 includes an arm main body 33 made up of a first arm part 34 and a second arm part 35, and a spindle 37 forming a pivoting part 36.

The first arm portion 34 has an arc shape extending in the circumferential direction around the rotation axis A of the pivot portion 36, and is inserted into the insertion hole 21a of the base body 21. A tip of the first arm portion 34 located on the outside in the vehicle width direction Y is connected to the lid 30.

Referring to FIGS. 5 and 12, the second arm portion 35 is plate-shaped, inserted into the gap 29 between the end wall portions 25 and 26, and protrudes inward from the bearing portion 24 in the vehicle width direction Y. The first arm portion 34 is mechanically connected to the inner end of the second arm portion 35 in the vehicle width direction Y. A cylindrical portion 35a having an insertion hole 35b having a non-circular cross section is formed at the outer end in the vehicle width direction Y of the second arm portion 35 that is inserted into the gap 29. A spindle 37 is attached to the cylindrical portion 35a through the insertion hole 35b. The cylindrical portion 35a and the spindle 37 constitute a pivot portion 36.

The spindle 37 includes a mounting rod 37a, a flange portion 37b, and a shaft portion 37c. The spindle 37 is inserted into and attached to the first arrangement part 25a, which is a circular through hole, of the bearing part 24 from above in the vehicle height direction Z.

The attachment rod 37a is a rod body with a non-circular cross section corresponding to the shape of the insertion hole 35b, is attached through the insertion hole 35b, and rotates together with the cylindrical portion 35a.

The flange portion 37b is connected to the upper end of the mounting rod 37a, and is located above the cylindrical portion 35a in the vehicle height direction Z. The flange portion 37b has a circular shape with the same diameter as the circular cylindrical portion 35a when viewed from the direction in which the rotation axis A of the pivot portion 36 extends. As shown most clearly in FIG. 12, the flange portion 37b is rotatably supported on the hole wall of the first arrangement portion 25a of the end wall portion 25. As shown most clearly in FIG. Referring to FIGS. 8A, 8B, and 12, a shaft portion 37d that pivotally supports the input cam 52 is protruded from the center of the flange portion 37b. The flange portion 37b is further provided with an engagement groove 38 in which the lock pin 41 engages, and a recess 39 forming the differential mechanism 60. Note that the engagement groove 38 and the recess 39 will be described in detail later.

Continuing to refer to FIGS. 5, 8B, and 12, the shaft portion 37c is provided at the lower end of the mounting rod 37a, and protrudes downward in the vehicle height direction Z from the cylindrical portion 35a. The shaft portion 37c is disposed within a shaft hole 26a formed in the end wall portion 26 facing the first arrangement portion 25a in the vehicle height direction Z, and is rotatably supported by the hole wall of the shaft hole 26a. .

Referring to FIGS. 5 and 13, the lock pin 41 is arranged in the second arrangement part 25b of the bearing part 24. Referring to FIGS. 8A and 8B, the lock pin 41 includes a cylindrical portion 41a and a lock pin body 41b.

The lock pin 41 is rotatable between a locked position shown in FIGS. 13 and 14 and an unlocked position shown in FIGS. 15 and 16.

Referring to FIGS. 5 and 13, the cylindrical portion 41a is fitted into a shaft portion 25d formed in a second arrangement portion 25b consisting of a concave opening at the upper end, and has a rotation axis parallel to the rotation axis A of the pivot portion 36. It can be rotated around B. The rotational axes A and B do not need to be parallel in a strict geometrical sense, as long as rotation of the lock pin 41 and engagement with the engagement groove 38 are not inhibited.

Referring to FIGS. 8A and 8B, the lock pin body 41b protrudes forward in the vehicle length direction X from the cylindrical portion 41a so as to be adjacent to the flange portion 37b of the spindle 37. The thickness of the lock pin main body 41b in the vehicle height direction Z (direction in which the rotating shaft B extends) is thicker than the thickness of the flange portion 37b of the spindle 37.

A lower portion of the lock pin body 41b in the vehicle height direction Z constitutes an engagement convex portion 42 that engages with the engagement groove 38. The upper portion of the lock pin body 41b in the vehicle height direction Z constitutes a cam follower 43 that can come into contact with the cam surface 53a of the input cam 52. That is, the engagement convex portion 42 and the cam follower 43 are integrally provided adjacent to each other in the vehicle height direction Z. The lock pin main body 41b is further provided with an attachment portion 44 to which a torsion spring 46 is attached.

Here, the engagement groove 38 of the spindle 37 and the engagement convex portion 42 of the lock pin 41 will be explained.

Referring to FIGS. 8B and 9, the engagement groove 38 of the spindle 37 is recessed inward from the outer peripheral surface of the flange portion 37b. The engagement groove 38 is defined by a base surface 38a, a contact surface 38b, and a restriction surface 38c. A guide surface 38d is formed at the outer end of the contact surface 38b of the engagement groove 38.

The base surface 38a has a flat fan shape extending along the XY plane. When the spindle 37 is disposed on the bearing portion 24 (see FIG. 5), the base surface 38a is located below the lock pin 41 in the vehicle height direction Z.

The contact surface 38b is a flat surface that protrudes from the base surface 38a in the orthogonal direction and extends in the radial direction of the flange portion 37b. The direction in which the abutting surface 38b extends does not have to be the radial direction of the flange portion 37b in a geometrically strict sense, as long as it does not impede engagement and disengagement of the lock pin 41. Further, the abutment surface 38b does not need to be a flat surface in the strict geometrical sense, as long as it does not impede engagement and disengagement of the lock pin 41.

The regulating surface 38c is a flat surface that protrudes from the base surface 38a in a direction perpendicular to the base surface 38a and extends in a direction intersecting the contact surface 38b. Referring to FIG. 14, the regulating surface 38c extends along the engagement convex portion 42 in the lock position, and regulates the rotation of the lock pin 41 toward the rotation axis A of the pivot portion 36. The angle formed by the regulating surface 38c and the contact surface 38b is set to 90 degrees or more, preferably larger than 90 degrees and close to 90 degrees (for example, 92 degrees).

The guide surface 38d is a flat surface provided at the outer end of the abutting surface 38b in the radial direction of the flange portion 37b, and inclined toward the opposite side from the regulating surface 38c. More specifically, the guide surface 38d is formed when the spindle 37 is closed when rotating the lid 30 from the open position shown in FIG. 2 to the closed position shown in FIG. It is inclined in the rotating direction d2.

Referring to FIGS. 8A and 10, the engagement convex portion 42 of the lock pin 41 protrudes further toward the rotation axis A side of the pivot portion 36 than the cam follower 43. That is, the width of the engagement convex portion 42 in the circumferential direction around the rotation axis B of the lock pin 41 is larger than the width of the cam follower 43. Referring to FIG. 14, a distal end portion 42a of the engagement convex portion 42 on the opposite side from the cylindrical portion 41a is chamfered to have an arcuate cross section. When the arm 32 is rotated to the retracted position shown in FIG. 14, the opening rotation of the spindle 37 in the direction d1 rotates the lid 30 from the closed position shown in FIG. 3 to the open position shown in FIG. The contact surface 38b of the matching groove 38 can be contacted.

The lock pin 41 has a lock position shown in FIGS. 13 and 14 and an unlock position shown in FIGS. 15 and 16. In the locked position shown in FIGS. 13 and 14, the lid 30 in the closed position shown in FIG. 3 is locked immovably via the spindle 37. In the unlocked position shown in FIGS. 15 and 16, the lid 30 is unlocked via the spindle 37, allowing the lid 30 to be opened and closed. The rotation angle position of the lock pin 41 is defined as the direction in which the center line of the width of the engagement convex portion 42 in the circumferential direction around the rotation axis B extends.

As shown in FIG. 14, the locking position of the lock pin 41 is rotated toward the rotation axis A side of the pivot portion 36 from the first rotation angle position where the engagement convex portion 42 extends in a direction orthogonal to the contact surface 38b. The second rotation angle position is set at the second rotation angle position. As shown in FIG. 16, the unlock position of the lock pin 41 is set at a rotational angle position where the engagement convex portion 42 abuts the outer periphery of the flange portion 37b of the spindle 37.

The first rotational angular position where the engagement protrusion 42 extends perpendicularly to the abutment surface 38b is such that when the lid 30 is tampered with, the abutment surface 38b contacts (presses) the engagement protrusion 42. ) is the limit position where rotation of the lock pin 41 toward the unlock position can be prevented. The area closer to the rotation axis A than the first rotation angle position including the second rotation angle position described above is an opening prevention area that can prevent unauthorized opening of the lid 30, and the rotated engagement protrusion 42 is placed in this area on the contact surface. When pressed by 38b, the lock pin 41 rotates toward the lock position. However, the rotation of the lock pin 41 is restricted by contact of the engagement groove 38 with the restriction surface 38c. As a result, the open rotation of the spindle 37 in the direction d1 is prevented by the contact of the contact surface 38b with the engagement convex portion 42. As a result, the lid 30 cannot rotate to the open position shown in FIG. 2 and remains in the closed position shown in FIG. 3. Therefore, the locking pin 41 is locked at a second rotational angular position in which the engagement convex portion 42 is rotated toward the rotational axis A side of the pivot portion 36 from the first rotational angular position in which the engagement convex portion 42 extends in a direction orthogonal to the contact surface 38b. It is set to the position. However, the locking position of the lock pin 41 may be the posture in which the engagement convex portion 42 is located at the first rotation angle position.

On the other hand, the side farther from the rotation axis A than the first rotation angle position where the engagement convex portion 42 extends perpendicularly to the contact surface 38b is an area where unauthorized opening of the lid 30 cannot be prevented. When the contact surface 38b presses the engagement convex portion 42 that has rotated into this area, a force that rotates the lock pin 41 in a direction away from the rotation axis A of the pivot portion 36 acts on the lock pin 41. As a result, the lock pin 41 rotates toward the unlocked position shown in FIG. 16, and the engagement convex portion 42 disengages from the engagement groove 38. As a result, the spindle 37 is rotatable in the direction d1. Therefore, the engagement protrusion 42 is further away from the rotation axis A of the pivot portion 36 than the first rotation angle position extending perpendicularly to the contact surface 38b, and the engagement protrusion 42 is formed on the outer periphery of the flange portion 37b of the spindle 37. The rotation angle position at which the lock pin 42 abuts is set to the unlock position of the lock pin 41.

Referring to FIGS. 8A and 8B, the cam follower 43 is constituted by a portion of the lock pin main body 41b that is above the engagement convex portion 42. The cam follower 43 protrudes further forward in the vehicle length direction X than the engaging convex portion 42 . Of the tip of the cam follower 43 on the opposite side from the cylindrical portion 41a, a corner portion located on the rotation axis A side (outside in the vehicle width direction Y) of the pivot portion 36 is provided with an arc-shaped chamfer that slides into contact with the cam surface 53a. A portion 43a is provided. When the lock pin 41 is in the lock position shown in FIGS. 13 and 14, the gap between the cam follower 43 and the cam surface 53a of the input cam 52 is the gap between the engagement convex portion 42 and the abutting surface 38b of the spindle 37. larger than the gap between. Therefore, when the lid 30 is opened when the lock pin 41 is in the locked position, the contact surface 38b contacts the engagement protrusion 42 due to the rotation of the spindle 37, and the cam surface 53a contacts the cam follower 43. do not. This prevents the lock pin 41 from rotating toward the unlocked position via the input cam 52 due to unauthorized operation of the lid 30.

Referring to FIGS. 8B and 10, the attachment portion 44 is provided on the opposite side of the lock pin body 41b from the chamfered portion 43a of the cam follower 43. The mounting portion 44 is made of a frame body that protrudes inward in the vehicle width direction Y, and a torsion spring 46 is hooked onto the frame body.

Referring to FIGS. 5 and 13, the torsion spring 46 is arranged in the third arrangement part 25c of the bearing part 24, which is a recess with an opening at the upper end. The torsion spring 46 urges the lock pin 41 to rotate toward the rotation axis A of the pivot portion 36.

Referring to FIGS. 4 and 5, the drive mechanism 50 includes one motor 51 and an input cam 52.

The motor 51 is a drive source that can rotate forward and reverse by controlling an electrically connected drive circuit (not shown) by an ECU (Electronic Control Unit). By normal rotation, the motor 51 rotates the input cam 52 and the spindle 37, rotates the lock pin 41 from the lock position to the unlock position, and moves the motor 51 to the retreat position shown in FIG. 3 via the input cam 52 and the differential mechanism 60. The arm 32 is rotated to the extended position shown in FIG. Due to the reverse rotation, the motor 51 rotates the arm 32 from the advanced position shown in FIG. 2 to the retracted position shown in FIG. 3 via the input cam 52 and the differential mechanism 60. This allows the lock pin 41 to rotate from the unlocked position shown in FIG. 15 to the locked position shown in FIG. 13 due to the biasing force of the torsion spring 46.

Referring to FIGS. 5 and 12, the input cam 52 is a cam member that is placed on the flange portion 37b of the spindle 37 placed in the first placement portion 25a and rotates by the driving force received from the motor 51. The input cam 52 includes a cam surface 53a that transmits the driving force received from the motor 51 to the lock pin 41 and moves the lock pin 41 from the locked position toward the unlocked position. In addition, the input cam 52 is integrally provided with a convex portion 54 that constitutes a differential mechanism 60 that transmits the driving force received from the motor 51 to the spindle 37 . Note that the convex portion 54 will be described in detail later.

Referring to FIGS. 8A and 8B, the input cam 52 includes a main body 52a that is fan-shaped when viewed from the direction in which the rotation axis A of the pivot portion 36 extends, and a mounting portion 52b that protrudes from the center of the main body 52a. Referring to FIG. 4, the attachment portion 52b passes through the through hole 28b, projects out of the cover 28, and is connected to the motor 51. The attachment portion 52b protrudes so as to extend along the rotation axis A, and has a non-circular cross-section including a plurality of radially protruding protrusions on the outer peripheral surface. However, the attachment portion 52b may be provided on the motor 51 side and connected to the input cam 52.

Referring to FIG. 12, a shaft hole 52c is provided at the center of the input cam 52. The input cam 52 is pivotally supported on the flange portion 37b by fitting the shaft hole 52c into the shaft portion 37d of the spindle 37, and rotates around the rotation axis A of the pivot portion 36. That is, the rotation axis A of the pivot portion 36 coincides with the rotation axis of the input cam 52.

Referring to FIGS. 8B and 11, a notch 53 is formed in the main body 52a to allow the engagement protrusion 42 to engage with the engagement groove 38. The notch 53 is recessed inward from the outer peripheral surface of the input cam 52 and penetrates in the vehicle height direction Z. The input cam 52 is arranged adjacent to the spindle 37 along the rotation axis A of the pivot portion 36 such that the notch 53 is located above the engagement groove 38 .

Viewed from the direction in which the rotation axis A of the pivot portion 36 extends, the angular range α of the notch 53 around the rotation axis A of the pivot portion 36 is formed to have a width that allows the engagement groove 38 to be exposed. More specifically, the open rotation moves the arm 32 in the retracted position shown in FIG. 3 to the advanced position shown in FIG. 2, and the closed rotation moves the arm 32 in the advanced position shown in FIG. 2 to the retracted position shown in FIG. The cutout 53 is formed in an angular range α in which the engagement groove 38 of the spindle 37 is exposed at any time of rotation.

One of the wall surfaces defining the notch 53 is a cam surface that transmits the rotational force of the input cam 52 and rotates the lock pin 41 in the locked position shown in FIG. 14 toward the unlocked position shown in FIG. 53a. Specifically, the notch 53 is defined by a cam surface 53a and a facing surface 53b that face each other in the circumferential direction around the rotation axis A of the pivot portion 36, and an inner circumferential surface 53c that extends in the circumferential direction. The cam surface 53a is located on the rear side in the direction d1 in which the input cam 52 rotates open. The cam surface 53a bulges in an arc shape toward the opposing surface 53b.

Referring to FIGS. 5 and 8A, the differential mechanism 60 includes a concave portion 39 of the spindle 37 and a convex portion 54 of the input cam 52. However, the recess 39 may be provided on the input cam 52 and the protrusion 54 may be provided on the spindle 37.

The convex portion 54 is provided on the outer periphery of the lower surface of the input cam 52 that faces the spindle 37 . The convex portion 54 is fan-shaped when viewed from the direction in which the rotation axis A of the pivot portion 36 extends, and protrudes from the input cam 52 toward the spindle 37 .

The recess 39 is provided in the flange portion 37b of the spindle 37. The recess 39 is a fan-shaped groove that is depressed inward from the outer circumferential surface of the flange portion 37b and has an open upper surface facing the input cam 52, and has a convex portion 54 disposed therein (see FIG. 14).

Referring to FIG. 14, in the circumferential direction around the rotation axis A of the pivot portion 36, the angular range β that forms the convex portion 54 is smaller than the angular range γ that forms the recessed portion 39. As a result, a gap 61 corresponding to the difference between the angular ranges β and γ is formed between the convex portion 54 and the concave portion 39 in the circumferential direction around the rotation axis A. The angular range (γ-β) of this gap 61 is a differential angle range in which the pivot portion 36 is rotated with a delay relative to the start of rotation of the input cam 52.

The differential angle range (γ-β) is larger than the rotation angle of the input cam 52 when the lock pin 41 in the lock position is rotated beyond the first rotation angle position toward the unlock position. As a result, after the lock pin 41 in the locked position shown in FIG. 14 rotates beyond the first rotation angle position to the unlocked position, the opposing surfaces of the convex portion 54 and the concave portion 39 abut, and the spindle 37 is rotated. It begins to rotate. As a result, the arm 32 from the retracted position shown in FIG. 3 can be rotated to the extended position shown in FIG. 2 while rotating the lock pin 41 to the unlocked position shown in FIG. 16.

The lock release member 65 will be explained below.

The lock release member 65 includes a lever 70 and a transmission member 80. The transmission member 80 includes a wire 81 and a connected member 82 . The lever 70, a portion of the wire 81, and the connected member 82 are arranged on the upper surface of the cover 28.

Referring to FIG. 6, the cover 28 includes a base portion 28c, a recessed portion 28d, and raised portions 28e and 28f. In FIG. 6, only the outer shape of the lever 70 located at the initial position is shown in dotted lines for explanation.

The base portion 28c extends along the vehicle length direction X and the vehicle width direction Y. On the upper surface of the base 28c, a holding groove 28m and an allowance space 28n are defined by raised parts 28e and 28f. A held portion 81a (see FIG. 7) of the wire 81 is routed in the holding groove 28m, and a movable portion 81b (see FIG. 7) of the wire 81 is routed in the allowable space 28n.

The recessed portion 28d is provided on the outer side of the base portion 28c in the vehicle width direction Y, and is recessed circularly toward the lower side in the vehicle height direction Z with respect to the base portion 28c. A lever 70 is arranged on the upper surface of the recess 28d.

The raised portion 28e is provided on the rear side of the base portion 28c in the vehicle length direction X, and is raised upward in the vehicle height direction Z with respect to the base portion 28c. The raised portion 28e has side wall portions 28g, 28h and a protrusion 28i.

The side wall portion 28g is constituted by a portion of the raised portion 28e located inside in the vehicle width direction Y, and extends along the vehicle length direction X.

The side wall portion 28h is constituted by a portion of the raised portion 28e located on the rear side in the vehicle length direction X, and extends along the vehicle width direction Y.

The protrusion 28i is constituted by a portion of the protrusion 28e located on the outside in the vehicle width direction Y, and protrudes into the allowable space 28n. The protrusion 28i has a connected member 82 (see FIG. 7) and a wire 81 (see FIG. 7) that move when the lever 70 rotates in conjunction with the arm 32 when the drive mechanism 50 rotates the arm 32 to the advanced position. ) can be contacted.

The raised portion 28f is provided on the front side of the base portion 28c in the vehicle length direction X, and is raised upward in the vehicle height direction Z with respect to the base portion 28c. The raised portion 28f has a guide portion 28k and a guide wall 28l.

The side surface 28j of the raised portion 28f extends parallel to the inner surface of the side wall portion 28g so as to face the side wall portion 28g.

The holding groove 28m is defined by the base portion 28c, a portion of the side wall portion 28g, and the side surface 28j of the raised portion 28f.

The guide portion 28k is provided adjacent to the rear side in the vehicle length direction X of the side surface 28j that defines the holding groove 28m, and protrudes in an arc shape toward the allowable space 28n.

The guide wall 28l is provided adjacent to the outside of the guide portion 28k in the vehicle width direction Y, and extends obliquely from the inside in the vehicle width direction Y to the front side in the vehicle length direction X toward the outside. More specifically, the guide wall 28l extends from the guide portion 28k toward a protrusion (connection portion) 70b, which will be described later, when the lever 70 is located at the initial position. That is, as it goes from the guide part 28k to the recessed part 28d, it is inclined away from the recessed part 28d to the front side in the vehicle length direction X.

The allowable space 28n is defined by the base 28c, a portion of the side wall 28g, the side wall 28h, the protrusion 28i, a portion of the guide portion 28k, and the guide wall 28l. The allowable space 28n allows the movable portion 81b (see FIG. 7) of the wire 81 to move as the lever 70 rotates.

A reference line S is set on the cover 28. The reference line S is a straight line that passes through the rotation axis A of the lever 70 and touches the rear side of the guide portion 28k in the vehicle length direction X in a cross section perpendicular to the rotation axis A.

To explain the positional relationship between the guide wall 28l and the protrusion 28i with respect to the reference line S, the guide wall 28l is located on the front side in the vehicle length direction X with respect to the reference line S, and the protrusion 28i is located on the front side with respect to the reference line S. It is located on the rear side in the vehicle length direction X. That is, the protrusion 28i is provided on the opposite side of the reference line S to the guide wall 28l.

4 and 7, the lever 70 disposed on the upper surface of the cover 28 has a lever main body 70a and a protrusion 70b, and is centered around a rotation axis that coincides with the rotation axis A of the pivot portion 36. It rotates together with the input cam 52. The lever 70 rotates at different angles depending on whether it is operated by the drive mechanism 50 or by the transmission member 80. Specifically, the rotation angle of the lever 70 by the drive mechanism 50 is relatively larger than the rotation angle of the lever 70 by the transmission member 80.

In normal operation of the lid opening/closing device 10 by the drive mechanism 50, when the arm 32 rotates from the retracted position to the advanced position, the lever 70 moves from the initial position (first rotation angle position) shown in FIG. 21 to the position shown in FIG. It rotates through the lock release position (second rotation angle position) to the maximum rotation position (third rotation angle position) shown in FIG. Further, when the arm 32 rotates from the advanced position to the retracted position, the lever 70 rotates from the maximum rotation position to the unlocked position to the initial position.

When the lid opening/closing device 10 is operated by the transmission member 80 in an emergency, the lever 70 is rotated from the initial position shown in FIG. 25 to the unlocked position shown in FIG. 26 by operating the wire 81. As will be described in detail later, when the lever 70 rotates from the initial position to the unlocked position, the lock pin 41 rotates from the locked position to the unlocked position, and the lid 30 can be opened and closed manually.

The lever main body 70a has a substantially circular shape when viewed from the vehicle height direction Z, and has a predetermined thickness in the vehicle height direction Z. Furthermore, a mounting hole 70c is provided at the center of the lever body 70a so as to penetrate through the lever body 70a in the vehicle height direction Z. In the present embodiment, the mounting hole 70c is circular with the rotation axis A as the center when viewed from the vehicle height direction Z, and by being press-fitted into the mounting portion 52b, the lever 70 rotates relative to the input cam 52. It is installed in such a way that it does not. However, the mounting hole 70c may be formed to have a non-circular cross-section corresponding to the cross-sectional shape of the mounting portion 52b of the input cam 52.

The protruding portion 70b protrudes radially outward from a portion of the outer periphery of the lever body 70a. That is, the protruding portion 70b protrudes radially outward with respect to the rotation axis A. The protrusion 70b has plate-shaped support plates 70d and 70e. The support plate 70d is provided flush with the upper surface 70f, which is the upper surface of the lever body 70a, and a support hole 70h penetrating in the vehicle height direction Z is provided approximately at the center of the support plate 70d. The support plate 70e is provided flush with a lower surface 70g, which is the lower surface of the lever body 70a, and a support hole 70i penetrating in the vehicle height direction Z is provided approximately in the center of the support plate 70e. . A member to be connected 82 is rotatably connected to the hole walls of the support holes 70h and 70i. A gap is formed between the support plates 70d and 70e, allowing rotational movement about the axes of the support holes 70h and 70i of the connecting portion 82a of the connected member 82.

Hereinafter, with reference to FIGS. 21, 22, and 24, the initial position (first rotation angle position), unlocked position (second rotation angle position), and maximum rotation position (third rotation angle position) of the lever 70 will be explained. ) settings will be explained in detail.

Referring to FIG. 21, in the initial position, the protrusion 70b is located on the d2 side in the direction around the rotation axis A with respect to the reference line S at an angle θ1. When the lever 70 is in the initial position, the arm 32 shown in FIG. 3 is in the retracted position, and the lock pin 41 shown in FIGS. 13 and 14 is in the locked position. At the initial position, the protruding portion 70b is located further forward in the vehicle length direction X than the guide portion 28k.

Referring to FIG. 22, the unlock position is set to the rotation angle position of the lever 70 when the center of the protrusion 70b, more specifically, the support holes 70h, 70i, is located on the reference line S. . Here, the rotation angle of the lever 70 between the initial position and the unlocked position is θ1. The angle θ1 is larger than the rotation angle of the input cam 52 when moving the lock pin 41 from the locked position shown in FIG. 13 to the unlocked position shown in FIG. 15. Furthermore, the angle θ1 is smaller than the rotation angle of the input cam 52 when the lid 30 is moved to the open position shown in FIG. In this embodiment, the angle θ1 is equal to the rotation angle of the input cam 52 when the lid 30 is rotated to the extent that the user's finger can be inserted between the lid 30 and the side panel 1. When the lever 70 in the initial position is rotated to the unlocked position, the lock pin 41 in the locked position can be rotated to the unlocked position via the input cam 52 and spindle 37.

Referring to FIG. 24, the maximum rotational position is set to the rotational angular position of the lever 70 when the input cam 52 rotates by an angle θ2 in the opening rotation direction d1 from the unlocked position. That is, at the maximum rotational position, the protrusion 70b is located at an angle θ2 on the opposite side of the initial position around the rotation axis A with respect to the reference line S, and is located on the outer side in the vehicle width direction Y than the protrusion 28i. It is located in The rotation angle (θ1+θ2) obtained by adding the angle θ1 between the initial position and the unlocked position and the angle θ2 between the unlocked position and the maximum rotational position is equal to the rotational angle of the input cam 52 by the motor 51. Therefore, when the lever 70 is located at the maximum rotation position, the arm 32 shown in FIG. 2 is located at the extended position.

Referring to FIGS. 7 and 21, one end of the wire 81 is disposed within the cover 28 and connected to the lever 70 via a connected member 82, and the other end of the wire 81 projects outside from the cover 28 and is not shown in the figure. Not connected to the operating lever. The operating lever is disposed inside the hood or trunk of the automobile, and the operating force of the operating lever is transmitted to the lever 70 via the wire 81 and the connected member 82. Specifically, the lever 70 is rotated by pulling the operating lever.

Referring to FIG. 21, in this embodiment, the wire 81 includes a held portion 81a and a movable portion 81b. The held portion 81a is a portion whose movement is suppressed by being held in the holding groove 28m when the input cam 52 is rotated by the motor 51, that is, when the lid 30 is opened and closed during normal operation. The movable portion 81b is a portion that is connected to the held portion 81a and moves in the allowable space 28n as the lever 70 rotates when the lid 30 opens and closes under normal conditions.

Referring to FIGS. 2 and 4, a motor 51 is disposed above the cover 28 in the vehicle height direction Z, and the allowable space 28n (see FIG. 6) is covered by the motor 51. Therefore, movement of the movable portion 81b (see FIG. 21) in the vehicle height direction Z is restricted by the top surface of the base portion 28c (see FIG. 21) and the bottom surface of the motor 51.

Referring to FIG. 7, the wire 81 is made of flexible synthetic resin, such as nylon. The shape of the cross section perpendicular to the extending direction of the wire 81 may be any shape such as a round shape or an H shape.

The connected member 82 has a connecting portion (base end portion) 82a and a connected portion 82b, and is made of a material that is relatively harder than the wire 81.

The connecting portion 82a has a cylindrical shape, and one end 81c of the wire 81 on the lever 70 side is connected to the connecting portion 82a. Referring to FIG. 23, the connecting portion 82a is provided with a length that projects from the protruding portion 70b of the lever 70 and comes into contact with the protruding portion 28i of the cover 28 (see FIG. 6). However, the wire 81 may be directly connected to the connected portion 82b without providing the connecting portion 82a.

The connected portion 82b is provided at the end of the connecting portion 82a so as to be located at the tip of the wire 81. The connected portion 82b extends along a direction perpendicular to the extending direction of the connecting portion 82a. The shape of the cross section perpendicular to the extending direction of the connected portion 82b is circular. By inserting the end 82c of the connected portion 82b into the support hole 70h of the protruding portion 70b, and inserting the end 82d of the connected portion 82b opposite to the end 82c into the support hole 70i, the connected member 82 is rotatably connected to the lever 70. That is, the wire 81 is rotatably connected to the protrusion 70b via the connected member 82. Note that the connected member 82 may not be provided, and the wire 81 may be directly connected to the protrusion 70b.

Here, when referring to FIG. 21, when the lever 70 is located at the initial position, that is, when the lock pin 41 is located at the lock position, a straight line between the guide portion 28k and the protruding portion 70b in a cross section perpendicular to the rotation axis A. The distance is a distance (first distance) L1. More specifically, when the lever 70 is located at the initial position, the linear distance between the guide portion 28k and the center of the support hole 70h in a cross section perpendicular to the rotation axis A is the distance L1.

Referring to FIG. 24, when the lever 70 is located at the maximum rotation position, that is, when the arm 32 is located at the extended position, the linear distance between the guide portion 28k and the protrusion 70b in the cross section perpendicular to the rotation axis A is the distance (Second distance) is L2. More specifically, when the lever 70 is located at the maximum rotation position, the linear distance between the guide portion 28k and the center of the support hole 70h in a cross section perpendicular to the rotation axis A is the distance L2.

The length of the movable portion 81b of the wire 81 is longer than the distance L1 and longer than the distance L2. Further, the distances L1 and L2 are respectively the linear distance L0 (FIG. 22 Reference). In other words, the distances L1 and L2 are respectively the guide portion 28k and the protruding portion 70b in a cross section perpendicular to the rotation axis A when the support holes 70h and 70i of the lever 70 to which the cable 80 is connected are located on the reference line S. is longer than the straight line distance L0.

Next, the normal operation of the lid opening/closing device 10 by the drive mechanism 50 will be described with reference to FIGS. 19 and 20.

19 and 20 are graphs showing the movements of the input cam 52, arm 32, lock pin 41, lever 70, and wire 81 with respect to the rotational angular position of the motor 51. 19 shows a lid opening operation in which the drive mechanism 50 rotates the lid 30 from the closed position to the open position, and FIG. 20 shows a lid closing operation in which the drive mechanism 50 rotates the lid 30 from the open position to the closed position. Show the time.

Referring to FIG. 19, when rotating the lid 30 from the closed position to the open position, the motor 51 rotates normally from the initial rotation angle position (0) to the maximum rotation angle position (max). As a result, the input cam 52 rotates open in the direction d1 from the closed rotation angle position shown in FIGS. 13 and 14 to the open rotation angle position shown in FIGS. 17 and 18. During this time, the arm 32, lock pin 41, lever 70, and wire 81 operate as follows.

Since the cam surface 53a rotates together with the opening rotation of the input cam 52, the lock pin 41 in the locked position begins to move toward the unlocked position after a delay time corresponding to the clearance between the cam surface 53a and the cam follower 43 ( (See Sa1 in FIG. 19). On the other hand, because the rotational force of the input cam 52 is not transmitted to the spindle 37 due to the gap 61 of the differential mechanism 60, the arm 32 is stopped at the retracted position as shown by Sb1 in FIG. As the input cam 52 rotates, the lever 70 begins to move from the initial position toward the unlocked position (see Sd1 in FIG. 19).

When the input cam 52 rotates by the gap 61 of the differential mechanism 60 (differential angle range γ-β), the opposing surfaces of the concave portion 39 and the convex portion 54 come into contact (see Sb2 in FIG. 19). Therefore, after that, the rotational force of the input cam 52 is transmitted to rotate the spindle 37, so that the arm 32 in the retracted position begins to rotate toward the advanced position (see Sb3 in FIG. 19). The lock pin 41 continues to rotate toward the unlocked position due to the sliding contact between the cam surface 53a and the cam follower 43.

As the spindle 37 rotates, the engagement convex portion 42 comes into sliding contact with the guide surface 38d following the sliding contact between the cam surface 53a and the cam follower 43 (see Sa2 in FIG. 19). As a result, the lock pin 41 continues to rotate toward the unlocked position.

Thereafter, when the spindle 37 rotates to a position where the outer end of the guide surface 38d comes into sliding contact with the engagement projection 42, the lock pin 41 rotates to the unlock position (see Sa3 in FIG. 19). As shown in FIGS. 15 and 16, the lock pin 41 is pressed against the outer periphery of the flange portion 37b of the spindle 37 by the biasing force of the torsion spring 46, and is held in the unlocked position (see Sa4 in FIG. 19). Thereafter, as the input cam 52 rotates, the lever 70 rotates to the unlock position (see Sd2 in FIG. 19).

Subsequently, when the input cam 52 rotates to the open rotation angle position, the arm 32 rotates to the extended position via the spindle 37, as shown in FIGS. 17 and 18. As a result, the lid 30 rotates to the open position. In this state, the lock pin 41 is pressed against the outer periphery of the flange portion 37b by the biasing force of the torsion spring 46, and is maintained in the unlocked position. Further, as the input cam 52 rotates, the lever 70 rotates to the maximum rotation position (see Sd3 in FIG. 19).

While the lever 70 rotates from the initial position to the maximum rotation position, the movable part 81b moves within the allowable space 28n. Specifically, as shown in FIG. 21 to FIG. 23, the movable portion 81b moves toward the side wall portion 28h so as to bulge, and then, as shown in FIG. It is pulled outward in direction Y. Note that while the lever 70 rotates from the initial position to the maximum rotation position, only the movable portion 81b of the wire 81 moves, and the held portion 81a does not move. That is, the wire 81 is held at the maximum retracted position without being pulled in the extending direction (see Se1 in FIG. 19).

Referring to FIG. 20, when rotating the lid 30 from the open position to the closed position, the motor 51 reverses from the maximum rotation angle position (max) to the initial rotation angle position (0). As a result, the input cam 52 is rotated in the closed direction d2 from the open rotation angle position shown in FIGS. 17 and 18 to the closed rotation angle position shown in FIGS. 13 and 14. During this time, the arm 32, lock pin 41, lever 70, and wire 81 operate as follows.

As the input cam 52 closes, the lever 70 begins to rotate from the maximum rotation position toward the initial position.

Further, the cam surface 53a rotates together with the closing rotation of the input cam 52, but since the cam surface 53a rotates to a rotation angle position away from the cam follower 43, the lock pin 41 does not rotate and returns to the unlock position. It is held (see Sa5 in FIG. 20). Furthermore, because the rotational force of the input cam 52 is not transmitted to the spindle 37 due to the gap 61 of the differential mechanism 60, the arm 32 also does not rotate, as shown by Sb4 in FIG. 20.

When the input cam 52 rotates by the gap 61 of the differential mechanism 60 (differential angle range γ-β), the opposing surfaces of the concave portion 39 and the convex portion 54 come into contact (see Sb5 in FIG. 20). Therefore, after that, the rotational force of the input cam 52 is transmitted and the spindle 37 is rotated, so that the arm 32 in the advanced position begins to rotate toward the retreated position (see Sb6 in FIG. 20). At this time, the lock pin 41 does not move.

After the arm 32 begins to rotate toward the retracted position due to the closing rotation of the input cam 52, the lever 70 passes through the unlocked position (see Sd4 in FIG. 20).

When the engagement convex portion 42 is positioned on the guide surface 38d by the rotation of the spindle 37 (see Sa6 in FIG. 20), the lock pin 41 from the unlock position is moved toward the lock position by the urging force of the torsion spring 46. It begins to rotate (see Sa7 in FIG. 20).

Subsequently, when the spindle 37 is rotated to an angular position where the engagement protrusion 42 contacts the outer end of the contact surface 38b (see Sb7 in FIG. 20), the torsion spring 46 is rotated as shown in FIGS. 13 and 14. Due to the urging force, the lock pin 41 rotates to the lock position, comes into contact with a stopper 25i formed on the bearing portion 24, and stops (see Sa8 in FIG. 20).

Finally, the input cam 52, lever 70, and spindle 37 rotate by the clearance between the engagement groove 38 of the spindle 37 and the engagement convex portion 42 of the lock pin 41. As a result, the input cam 52 rotates to the closed rotation angle position, and the lever 70 rotates to the initial position. Further, the arm 32 is rotated to the retracted position via the spindle 37, and the lid 30 is rotated to the closed position.

While the lever 70 rotates from the maximum rotation position to the initial position, the movable portion 81b of the wire 81 moves within the allowable space 28n. Specifically, as shown in FIG. 24 to FIG. 22, the movable portion 81b moves inward in the vehicle width direction Y, and then moves toward the guide wall 28l. Thereafter, the movable part 81b moves until it extends along the guide part 28k and the guide wall 28l, as shown in FIG. Note that while the lever 70 rotates from the maximum rotation position to the initial position, only the movable portion 81b of the wire 81 moves, and the held portion 81a does not move. That is, the wire 81 is held at the maximum retracted position without being pulled in the extending direction (see Se2 in FIG. 20).

As described above, in the locking device 40 of this embodiment, the single motor 51 allows the lock pin to be rotated between the advanced position shown in FIG. 2 and the retracted position shown in FIG. 3 without inhibiting the rotation of the arm 32. 41, the lid 30 can be switched between a locked state and an unlocked state. Further, since only the movable portion 81b of the wire 81 moves in the allowable space 28n, movement of the entire wire 81 can be suppressed.

Next, the unlocking operation of the lid opening/closing device 10 by the lock releasing member 65 will be explained with reference to FIGS. 25 to 27.

25 and 26 are diagrams showing the positions of the lever 70, the wire 81, and the connected member 82 with respect to the operation stroke when the user operates the lock release member 65. FIG. 25 is a diagram when the operating stroke is at the initial position (0). FIG. 26 is a diagram when the operating stroke is at the maximum operating position (max).

When the operating lever (not shown) is operated from the initial position (0) to the maximum operating position (max), the wire 81 is pulled from the maximum retracted position to the advanced position (see Se1 in FIG. 27). As a result, the lever 70 is rotated from the initial position shown in FIG. 25 to the unlocked position shown in FIG. 26 by the wire 81 pulled using the guide portion 28k as a fulcrum (see Sd1 in FIG. 27).

The input cam 52 rotates together with the lever 70 (see Sc1 in FIG. 27), and the lock pin 41 in the locked position begins to rotate toward the unlocked position by the cam surface 53a (see Sa1 in FIG. 27). Further, the spindle 37 starts to rotate (see Sb2 in FIG. 27) when the input cam 52 rotates by the gap 61 (differential angle range γ-β) of the differential mechanism 60 (see Sb1 in FIG. 27).

When the lock pin 41 moves to the unlock position due to the rotation of the input cam 52 and the spindle 37, the lock pin 41 is moved to the flange portion 37b of the spindle 37 by the biasing force of the torsion spring 46, as shown in FIGS. 15 and 16. It is pressed against the outer periphery and held in the unlocked position (see Sa2 in FIG. 27). Further, when the lever 70 rotates to the unlocked position, the arm 32 rotates to the position shown by Sb3 in FIG. 27. At this time, in this embodiment, the lid 30 is opened from the side panel 1 to an extent that the user can grasp the lid 30.

When the user who has finished operating the operating lever (not shown) grasps the lid 30 from outside the vehicle and manually rotates it toward the open position shown in FIG. 2, the arm 32 further rotates toward the extended position. (See Sb4 in FIG. 27). At this time, the rotational force of the spindle 37 is not transmitted to the input cam 52 due to the gap 61 of the differential mechanism 60, so the input cam 52 does not rotate as shown in Sc2 in FIG. 27, and the lever 70 also moves as shown in Sd2 in FIG. It does not rotate as shown. During this time, the wire 81 is held at the advanced position (see Se2 in FIG. 27).

When the facing surfaces of the concave portion 39 and the convex portion 54 come into contact, the rotational force of the spindle 37 is transmitted, and the input cam 52 rotates to the vicinity of the open rotation angle position as shown in Sc3 in FIG. 27, and the lever 70 rotates to the vicinity of the maximum rotation position as shown in Sd3 in FIG. When the arm 32 is in the extended position, the input cam 52 is located with a gap of 61 minutes in the direction d2 from the open rotation angle position, and the lever 70 is in the position with a gap of 61 minutes in the direction d2 from the maximum rotation angle position. are doing. Further, the wire 81 is pulled by the lever 70 from the advanced position toward the maximum retracted position, but is not pulled to the maximum retracted position (see Se3 in FIG. 27).

Next, with reference to FIG. 28, the operation of the lid opening/closing device 10 when manually closing the manually opened lid 30 will be described.

When the lid 30 in the open state is operated to close, the lid 30 rotates from the open position (max) to the closed position (0). As a result, the arm 32 rotates from the advanced position to the retracted position (see Sb5 in FIG. 28). When the arm 32 starts rotating, the rotational force of the spindle 37 is not transmitted to the input cam 52 due to the gap 61 of the differential mechanism 60, so the input cam 52 does not rotate as shown in Sc4 in FIG. It does not rotate as shown in Sd4 of 28. When the opposing surfaces of the concave portion 39 and the convex portion 54 come into contact, the rotational force of the spindle 37 is transmitted, and the input cam 52 rotates toward the closed rotation angle position as shown in Sc5 in FIG. 28, and the lever 70 rotates toward the initial position as shown at Sd5 in FIG.

When the spindle 37 is rotated by operating the lid 30 to a position where the guide surface 38d comes into sliding contact with the engagement protrusion 42 (see Sb6 in FIG. 28), the biasing force of the torsion spring 46 moves the lock pin 41 to the unlocked position. begins to rotate toward the lock position (see Sa3 in FIG. 28).

Subsequently, when the spindle 37 rotates to an angular position where the engagement protrusion 42 contacts the outer end of the contact surface 38b (see Sb7 in FIG. 28), the lock pin 41 is moved to the lock position by the biasing force of the torsion spring 46. It rotates (see Sa4 in FIG. 28) and stops when it comes into contact with the stopper 25i. The input cam 52 rotates toward the closed rotation angle position due to the sliding contact between the cam surface 53a and the cam follower 43 (see Sc6 in FIG. 28). The lever 70 rotates together with the input cam 52 toward the initial position (see Sd6 in FIG. 28). Then, the input cam 52 and the lever 70 stop at a position separated by a clearance between the cam surface 53a and the cam follower 43 in the direction d1 from the initial position (see Sc7 and Sd7 in FIG. 28).

While the arm 32 rotates from the advanced position to the retracted position, the movable part 81b of the wire 81 moves in the allowable space 28n so as to approach the guide wall 28l, with a portion remaining in the holding groove 28m (Fig. 28 (See Se4). When the lock pin 41 rotates to the lock position due to the biasing force of the torsion spring 46, the movable part 81b is pulled outward in the vehicle width direction Y by the lever 70 and moves toward the maximum retracted position (FIG. 28 (See Se5). Thereafter, the wire 81 stops without being pulled to the maximum retracted position (see Se6 in FIG. 28).

As described above, in the lock device 40 of this embodiment, even if the lock pin 41 cannot be rotated by the drive mechanism 50, the lid 30 can be opened by operating the lock release member 65 and operating the lid 30. Can be opened and closed.

According to the lid opening/closing device 10 according to the present embodiment, when the operating lever (not shown) is operated and the wire 81 is operated, the lever 70 is rotated from the initial position to the unlocked position, and the input cam 52 is also rotated. It is rotated together with the lever 70. Here, the lock pin 41 is in the lock position at the initial position, and the lock pin 41 is in the unlock position at the unlock position. Therefore, the lid 30 can be manually rotated by operating a control lever (not shown). Further, in the present embodiment, the lock release mechanism can be configured by simply attaching the lever 70 connected to the wire 81 via the connected member 82 to the input cam 52, and the lid 30 can be manually unlocked. Therefore, the configuration can be simplified.

When the input cam 52 is rotated by the motor 51, the length of the portion of the wire 81 that extends from the point in contact with the guide portion 28k to the protruding portion 70b, that is, the length of the movable portion 81b, is equal to or greater than the distance L1 and greater than the distance L2. It is. Further, the lever 70 rotates between the initial position and the maximum rotation position through the unlock position. Therefore, movement of the held portion 81a during the opening/closing operation of the lid 30 by the motor 51 can be suppressed. Therefore, the range in which the wire 81 moves during normal opening and closing of the lid 30 can be restricted, and operational noise and malfunction can be prevented.

The protrusion 70b protrudes radially outward from the lever main body 70a. Therefore, the moment required when manually opening the lid 30 can be easily obtained.

Since the lever 70 is assembled by fitting into the attachment portion 52b of the input cam 52, the assembly work efficiency can be improved.

The wire 81 is rotatably attached to the lever 70 via a connected member 82. Therefore, the lever 70 can rotate smoothly, and the lid 30 can be easily opened and closed automatically or manually.

The connected member 82 is provided with a connecting portion 82a, and by adjusting the length of the connecting portion 82a, bending of the wire 81 when the input cam 52 rotates can be restricted. In other words, the wire 81 can be prevented from taking an unintended shape. Therefore, it is possible to prevent malfunctions from occurring during the opening/closing operation of the lid 30.

Since the cover 28 includes the guide wall 28l, the position of the wire 81 can be regulated when the lid 30 is closed. Therefore, if it is necessary to manually unlock the lid 30, the wire 81 can be easily pulled.

When the arm 32 moves to the advanced position, the wire 81 and the connected member 82 come into contact with the protrusion 28i, so that the bending of the wire 81 can be restricted. In other words, the shape of the wire 81 can be prevented from becoming an unintended shape. Therefore, it is possible to prevent malfunctions from occurring during the opening/closing operation of the lid 30.

The distances L1 and L2 are each longer than the straight-line distance L0 between the protruding portion 70b and the guide portion 28k when the lever 70 is located at the second rotation angle position (unlocked position). Therefore, movement of the held portion 81a during the opening/closing operation of the lid 30 by the motor 51 can be suppressed. Therefore, the range in which the wire 81 moves during normal opening and closing of the lid 30 can be restricted, and operational noise and malfunction can be further prevented.

Note that the present invention is not limited to the configuration of the embodiment described above, and various changes are possible.

The drive mechanism 50 may be a dedicated mechanism that can move only the lock pin 41. That is, the lock pin 41 and the lid 30 may be operated by different drive mechanisms. Further, a gear may be used as the cam member of the drive mechanism 50. The cam may be provided on a separate member from the input cam 52 as long as it is movable in conjunction with the input cam 52. That is, the cam member may be composed of the input cam 52 that does not have the cam surface 53a and a separate member that has the cam surface 53a that interlocks with the input cam 52.

The object to be locked by the locking device 40 may be other than the lid 30 included in the lid opening/closing device 10.
