Hereinafter, an embodiment of a locking device embodying the present invention will be described with reference to FIGS.
[Overview of charging system]
As shown in FIG. 1, for example, a vehicle such as a plug-in hybrid vehicle is equipped with a charging system capable of charging a vehicle battery (not shown) by an external power source (a house, a charging stand, etc.). In this case, a lid 3 that opens and closes the power feeding port 2 of the vehicle body 1 is attached to the side wall of the vehicle body 1 so as to be rotatable around a shaft portion 3a extending in the vertical direction. A biasing member 4 such as a torsion spring for biasing the lid 3 to the open side is attached to the shaft portion 3a. An inlet 6 serving as a power receiving connector is provided at the center position of the lid box 5 of the power supply port 2. The inlet 6 is provided with a substantially cylindrical inlet casing 7, and a terminal portion 8 is provided inside the cylinder. The lid 3 corresponds to the lock target.

  As shown in FIG. 2, a charging cable 9 extending from an external power source can be connected to the inlet 6. The charging cable 9 is provided with a power supply plug 11 serving as a power supply side connector at the tip of the cable line 10. A terminal portion 12 that is paired with the terminal portion 8 of the inlet 6 is provided at the tip of the power supply plug 11. A lock arm 13 is attached to the power supply plug 11 so that the lock arm 13 can be rotated when it is connected to the inlet 6. The lock arm 13 has a claw portion 14 at the tip and an arm operation portion 15 at the base exposed to the outside. The lock arm 13 is provided with a biasing member 16 that constantly biases the lock arm 13 toward the closing side at a position near the arm operation unit 15. Note that the charging cable 9 corresponds to an object to be locked, and the lock arm 13 corresponds to an operation portion with a claw.

  When connecting the power supply plug 11 to the inlet 6, the power supply plug 11 is inserted straight toward the inlet 6. At this time, when the claw portion 14 comes into contact with the locking protrusion 17 on the upper surface of the inlet housing 7, the lock arm 13 is guided by the slope of the locking protrusion 17 and rotates against the urging force of the urging member 16. By moving, the locking protrusion 17 is raised. When the power supply plug 11 is completely inserted into the inlet 6, the lock arm 13 is rotated to the closing side by the urging force of the urging member 16. For this reason, the nail | claw part 14 is hooked on the latching protrusion 17, and the electric power feeding plug 11 is prevented from falling to the inlet 6. FIG.

  Inside the power supply plug 11, a plug connection detection unit 18 that detects that the charging cable 9 is connected to the inlet 6 is provided. When the charging cable 9 is connected to the inlet 6 and the claw portion 14 is locked to the locking protrusion 17, the lock arm 13 is closed. Therefore, when the plug connection detection unit 18 detects that the lock arm 13 is in a closed state, the plug connection detection unit 18 sends a plug connection detection signal notifying that the power supply plug 11 is connected to the inlet 6 via the terminal units 8 and 12. Output to the vehicle body 1.

[Configuration of locking device]
As shown in FIG. 1, the power supply port 2 is provided with a lock device 19 that can execute both the lock of the lid 3 and the lock of the charging cable 9 with one device. That is, the lock device 19 of this example is an integrated type in which one actuator serves as both a lid lock and a charging cable lock. On the back surface of the lid 3, a striker 20 that protrudes as a locking portion when the lid 3 is locked by the lock device 19 is projected. A locking groove 21 having a predetermined groove depth is recessed at the tip of the striker 20. For example, a push-operated trigger switch 22 is provided at the power supply port 2. The trigger switch 22 can detect, for example, the opening / closing of the lid 3 and the further pressing of the lid 3 in the closed state.

  As shown in FIG. 3, inside the housing 23 of the locking device 19, a lock bar 24 that can be locked to the lid 3 and the power supply plug 11 reciprocates along its own longitudinal direction (Y-axis direction in FIG. 3). It is assembled in a movable manner. The lock bar 24 is composed of a member in which two parts of an elongated cylindrical lock pin 25 and a lock rod 26 that supports the lock pin 25 at the root are combined. The lock bar 24 (lock pin 25) reciprocates in a direction (Y-axis direction in FIG. 3) intersecting the operation direction of the lock arm 13 (arrow Z ′ direction in FIG. 3). The lock rod 26 is connected to a lock motor 29 via a lock stopper 27 and a gear shaft 28. The motor shaft of the lock motor 29 is connected to the gear shaft 28 via a spur gear 30. The spur gear 30 includes a small-diameter cylindrical gear 31 disposed on the motor shaft and a large-diameter cylindrical gear 32 disposed near the end of the shaft shaft. The gear shaft 28 is rotatable around the shaft axis L1. The gear shaft 28 and the lock motor 29 are arranged so that the motor shaft and the shaft shaft are arranged in parallel to each other. The lock bar 24 corresponds to a lock member, the lock stopper 27 corresponds to a transmission member, and the lock motor 29 corresponds to an actuator.

  The gear shaft 28 is connected to the lock stopper 27 via the feed screw 33. The feed screw 33 includes a screw shaft 34 disposed on the gear shaft 28 and a nut portion 35 disposed on the lock stopper 27. The feed screw 33 converts the rotational motion of the gear shaft 28 into the linear motion of the lock stopper 27.

  On the back surface of the lock stopper 27, a locking protrusion 36 that protrudes toward the lock rod 26 is provided, and the locking protrusion 36 is inserted into the insertion hole 37 of the lock rod 26. Between the lock rod 26 and the lock stopper 27, an urging member 38 that urges the lock rod 26 in the unlocking direction (direction of arrow Y2 in FIG. 3) with respect to the lock stopper 27 is interposed. The biasing member 38 is made of a coil spring, for example.

  As shown in the enlarged circle of FIG. 3, the back surface of the lid box 5 is formed as a strength receiving surface 39 that holds the lock pin 25 in the lock position at the same position. Even if the strength receiving surface 39 moves so that the lock pin 25 in the lock position is pushed upward (in the direction of arrow Z1 in FIG. 3), the lock pin 25 is supported in a flat surface to support the lock pin 25 in the unlock position. Hold on.

  As shown in FIG. 4, the biasing member 38 has one end attached to the locking hole 40 of the locking protrusion 36 and the other end fixed to the protrusion 41 on the inner surface of the insertion hole 37. A pair of pivot shafts 42 project from the base of the lock pin 25 and are pivotally supported by a pair of engagement holes 43 on the side wall of the lock rod 26. In this way, by allowing the lock pin 25 to rotate a predetermined amount slightly around the axis L2 of the rotation shaft 42, the lock bar 24 rides on the claw portion 14 of the lock arm 13 and the locking groove 21 of the striker 20. This facilitates switching of the lock bar 24 to the locked position.

[Configuration of latch mechanism]
As shown in FIG. 4, the lock device 19 is provided with a latch mechanism 44 that fixes the lock bar 24 moved to the lock position at the lock position. The latch mechanism 44 will be described below. At a position adjacent to the lock rod 26, a rotation locking piece 45 that can be locked with the lock rod 26 moved in the locking direction intersects with the movement direction of the lock bar 24. It is provided so as to be rotatable along a plane. The rotation locking piece 45 is sandwiched from both sides by a pair of rotation shafts 46 protruding from the inner surface of the housing 23, and is pivotally supported around the axis L3. A biasing member 47 that constantly biases the rotation locking piece 45 in the locking direction (the direction of arrow A1 in FIG. 4) is attached to the rotation locking piece 45. As the urging member 47, for example, a coil spring is used. The rotation locking piece 45 corresponds to the movable locking portion.

  On the bottom surface of the lock rod 26, there is provided a stepped portion 48 capable of locking a rotation locking piece 45 that rotates in the locking direction (arrow A1 direction in FIG. 4) when the lock bar 24 reaches the locking position. Yes. A protrusion 49 projecting from the lower portion of the rotation locking piece 45 can be locked to the stepped portion 48 during the locking operation. The stepped portion 48 corresponds to the locked portion.

  Further, on the back surface of the lock stopper 27, a pushing portion 50 that holds the rotation locking piece 45 in a state of rotating in the unlocking direction (the direction of arrow A2 in FIG. 4), and the lock of the rotation locking piece 45 A groove portion 51 that allows rotation in a direction (the direction of arrow A1 in FIG. 4) is provided. The groove 51 is provided with an unlocking slope 52 that can switch the rotation locking piece 45 in the locked state to the unlocked state. An abutting portion 53 protruding from the upper portion of the rotation locking piece 45 can abut against the unlocking slope 52 during the unlocking operation. Note that. The groove part 51 corresponds to an open part, and the unlocking slope 52 corresponds to an unlock switching part.

  As shown in FIGS. 5A and 5B, the lock motor 29 causes the gear shaft 28 to rotate in the unlocking direction (the direction of the arrow L1-b in FIG. 5B), and the lock stopper 27 and the lock bar 24 are unlocked. When the slider 19 is slid in the locking direction (arrow Y2 direction in FIG. 5B) and positioned at the unlock position, the lock device 19 is unlocked. At this time, the pressing portion 50 on the back surface of the lock stopper 27 presses the contact portion 53 of the rotation locking piece 45 and resists the urging force of the urging member 47 so that the rotation locking piece 45 is unlocked. The state is rotated in the direction of arrow A2 in FIG. Therefore, since the latch mechanism 44 is in the unlocked state, the sliding movement of the lock bar 24 is allowed.

  As shown in FIGS. 6 (a) and 6 (b), the gear shaft 28 is rotated in the locking direction (the direction of the arrow L1-a in FIG. 6 (b)) by the lock motor 29, and the lock stopper 27 and the lock bar 24 are in the locking direction. Move in the direction of arrow Y1 in FIG. At this time, when the lock bar 24 reaches the lock position and the groove 51 of the lock stopper 27 reaches the contact portion 53 of the rotation locking piece 45, the rotation locking piece 45 is biased by the biasing member 47. Accordingly, the projection 49 is locked to the stepped portion 48 in the locking direction (the direction of the arrow A1 in FIG. 6B). Therefore, the latch mechanism 44 is locked, and the sliding movement of the lock bar 24 at the time of locking becomes impossible.

  7A and 7B show a switching point of the lock device 19 from lock to unlock. When the locking device 19 is switched to unlocking, only the lock stopper 27 is slid in the unlocking direction (the direction of arrow Y2 in FIG. 7B). At this time, the unlocking slope 52 pushes the rotation locking piece 45 from above and rotates it in the unlocking direction (the direction of arrow A2 in FIG. 7B). Then, when the abutting portion 53 of the rotation locking piece 45 rides on the pushing portion 50 and the protrusion 49 of the rotation locking piece 45 is separated from the stepped portion 48, the fixing by the rotation locking piece 45 is released, The lock bar 24 catches up with the lock stopper 27 by the urging force of the urging member 38. Thereafter, the lock bar 24 and the lock stopper 27 are integrally moved in the unlocking direction (the arrow Y2 direction in FIG. 7B).

[Lock forced release mechanism]
As shown in FIG. 3, the lock device 19 is provided with a lock forced release mechanism 54 that allows the lock state of the lock device 19 to be manually released. This is because, when the lock device 19 is in a locked state, for example, when the lock motor 29 becomes inoperable due to a failure of the lock motor 29 or a circuit around the motor, unlock switching using the lock motor 29 as a drive source is performed. This is because it is impossible to deal with this.

  In this case, a pull cord 56 made of, for example, a wire or the like is attached to the stopper 55 at the end of the lock stopper 27 and is disposed inside the tip of the pull cord 56 (for example, in the luggage). When the pull cord 56 is pulled, the lock stopper 27 and the lock bar 24 slide and move in the unlocking direction (arrow Y2 direction in FIG. 3) while the lock motor 29 is rotated by manual force. Therefore, the lock bar 24 is pulled to the unlock side, and the lock device 19 is forcibly switched to the unlock state manually.

Next, operation | movement of the locking device 19 of this example is demonstrated using FIGS.
[Lidlock operation]
As shown in FIG. 8, when the lid 3 is opened and closed, if the lock bar 24 is in the unlock position, the lid lock is unlocked (see FIG. 5). When the lid 3 is closed when the lid lock is unlocked, the locking groove 21 of the striker 20 is positioned directly beside the lock pin 25. At this time, when the conditions for starting the lid lock are met, a current in the lock direction flows through the lock motor 29 for a predetermined time, and the lock motor 29 rotates in the lock direction. Therefore, the gear shaft 28 rotates in the locking direction due to the rotation of the motor, and the lock stopper 27 and the lock bar 24 slide together in the locking direction.

  When the lock bar 24 reaches the lock position and the stepped portion 48 of the lock bar 24 faces the protrusion 49 of the rotation locking piece 45, the rotation locking piece 45 is locked by the biasing force of the biasing member 47. The projection 49 of the rotation locking piece 45 is locked to the stepped portion 48. Therefore, the lock bar 24 is fixed at the lock position by the latch mechanism 44, and the locked state (see FIG. 6) is maintained. For this reason, the lid lock is in the locked state and the lid 3 is held in the closed state, so that the lid 3 cannot be opened by a third party or the like.

  When the lock bar 24 is locked, the strength receiving surface 39 on the back surface of the lid box 5 supports the lock bar 24 from above. Therefore, when the lock bar 24 is in the locked state, even if an external force that is pushed upward is applied to the lock pin 25, the lock force of the lock bar 24 is maintained by supporting the external force with the strength receiving surface 39. Is done.

  The start condition of the lid lock includes, for example, a simple vehicle door locking operation (door lock interlocking), a door lock interlocking on the assumption that the lid 3 is closed. In addition, the lid lock start condition may include establishment of ID verification by the electronic key system. An electronic key system is a type of wireless authentication in which ID verification (key verification) is performed wirelessly between a vehicle and an electronic key. For example, ID verification is performed in two-way narrowband radio (communication distance) triggered by communication from the vehicle. : Key operation free system etc. performed by several m).

[Lid unlock operation]
As shown in FIG. 9, when the lid 3 is in the closed state, if the lock bar 24 is in the locked position, the lock pin 25 is locked in the locking groove 21 of the striker 20, and the lid lock is locked ( (See FIG. 6). Incidentally, the lid 3 in the closed state can be pushed to the back against the urging force of the urging member 4 by the gap between the lock pin 25 and the locking groove 21.

  When the lid unlocking conditions are met, the unlocking direction current flows through the lock motor 29 for a predetermined time, and the lock motor 29 rotates in the unlocking direction. At this time, the gear shaft 28 is rotated in the unlocking direction by the rotation of the motor, and the lock stopper 27 and the lock bar 24 are integrated to start sliding movement in the unlocking direction. During the sliding movement in the unlocking direction, only the lock stopper 27 first moves in the unlocking direction. Along with this movement, the unlocking slope 52 of the lock stopper 27 gradually pushes the contact portion 53 of the rotation locking piece 45 downward, and the rotation engagement member 47 resists the urging force of the urging member 47. The stop piece 45 is rotated in the unlocking direction. Then, when the lock stopper 27 reaches the switching point, the contact portion 53 is detached from the groove portion 51 and rides on the pushing portion 50, and the protrusion 49 is detached from the stepped portion 48 (see FIG. 7).

  When the protruding portion 49 of the rotation locking piece 45 is detached from the stepped portion 48, the lock bar 24 catches up with the lock stopper 27 by the urging force of the urging member 38, and thereafter, the lock bar 24 and the lock stopper 27 are integrated. To slide in the unlocking direction. When the lock pin 25 is detached from the locking groove 21 of the striker 20, the lid lock is unlocked (see FIG. 5). Thereby, the opening operation of the lid 3 is permitted, and the lid 3 is opened by, for example, a hand.

  The conditions for starting the lid unlocking are, for example, a closed state when an operation of a predetermined button (switch) disposed in the vehicle, an unlocking operation of the vehicle door (door unlocking interlock), or ID verification of the electronic key system is established. There are operations such as pushing the lid 3 further into the back.

[Charging cable lock operation]
As shown in FIG. 10, when the lid 3 is in the open state, the lock bar 24 is in the unlocked position, so that the charging cable lock before connecting the charging cable 9 to the inlet 6 is in the unlocked state (see FIG. 5). Take. Therefore, the charging cable 9 can be connected to the inlet 6 by inserting the power supply plug 11 into the inlet 6. When the power supply plug 11 is inserted into the inlet 6 as far as it will go, the claw portion 14 of the lock arm 13 is caught by the locking protrusion 17 of the inlet 6.

  When the charging cable lock is in the unlocked state, after the charging cable 9 is connected to the inlet 6 and the charging cable lock start conditions are met, the lock motor 29 flows in the lock direction for a predetermined time, and the lock motor 29 moves in the lock direction. Rotate to. At this time, the lock bar 24, the lock stopper 27, and the gear shaft 28 move in the same manner as in the lid lock, the lock pin 25 comes into contact with the contact surface 57 on the upper surface of the claw portion 14, and the charging cable lock is locked (see FIG. 6). Therefore, the claw portion 14 of the lock arm 13 is pressed from above by the lock pin 25 and cannot be rotated to the open side, and the power supply plug 11 connected to the inlet 6 is pulled out of the inlet 6 by a third party or the like. Absent.

  The charging cable lock start condition may be, for example, that an operation switch dedicated to the charge cable lock is locked. The operation switch may be disposed in the power supply port 2 or in the vehicle. The other charging cable lock starting conditions are, for example, that a plug connection detection signal output from the plug connection detection unit 18 of the power supply plug 11 is input from the vehicle body 1 and the vehicle door is locked ( (Door lock interlock).

[Charging cable unlocking operation]
As shown in FIG. 11, when the charging cable lock is in the locked state (see FIG. 6), when the charging cable unlocking start condition is met, the unlocking direction current flows through the lock motor 29 for a predetermined time. It rotates in the unlocking direction. At this time, the lock bar 24, the lock stopper 27, and the gear shaft 28 move in the same manner as when the lid is unlocked, the lock pin 25 is retracted from the contact surface 57 on the upper surface of the claw portion 14, and the charging cable lock is unlocked. (See FIG. 5). Therefore, the lock arm 13 can be turned to the opening side, and the charging cable 9 can be pulled out from the inlet 6.

  The charging cable unlocking start condition may be, for example, that an operation switch dedicated to charging cable locking is unlocked. The other charging cable unlocking start conditions are, for example, that a plug connection detection signal output from the plug connection detection unit 18 of the power plug 11 is input from the vehicle body 1 and the vehicle door is unlocked (door (Unlocked).

According to the configuration of the present embodiment, the following effects can be obtained.
(1) When the lock pin 25 reaches the lock position, the rotation locking piece 45 rotates in the lock direction and engages with the stepped portion 48 of the lock rod 26, thereby fixing the lock pin 25 at the lock position. A latch mechanism 44 is provided. Therefore, the lock pin 25 that has reached the lock position can be held in the lock position with a strong structure in which the rotation locking piece 45 that is rotatably attached to the housing 23 is locked to the stepped portion 48. it can. For this reason, even when an external force in the unlocking direction is applied to the lock pin 25 at the time of locking, the lock pin 25 can be made difficult to move from the lock position. .

  (2) The lock pin 25 slides and reciprocates in a direction intersecting the operation direction of the lock arm 13 (arrow Z ′ direction in FIG. 3). Therefore, the configuration of the lock device 19 can be a simple structure in which the lock pin 25 is linearly reciprocated in a direction intersecting the rotational operation direction of the lock arm 13. Moreover, since the lock pin 25 is fitted and detached from the lock arm 13 and the striker 20 from the side, for example, even if there is no part arrangement space above the inlet 6, the lock device 19 is arranged on the side of the inlet 6. The mounting of the lock device 19 can be realized.

  (3) On the back surface of the lock stopper 27, an unlocking slope 52 for guiding the rotation locking piece 45 at the lock position to the unlock position is provided. Therefore, as the lock stopper 27 moves in the unlocking direction, it is possible to push the locked rotation engagement piece 45 in the unlocking direction on the unlocking slope 52, so that the latch mechanism 44 in the locked state is The original unlocked state can be restored.

  (4) Since the structure of the latch mechanism 44 is composed of the rotation locking piece 45, the urging member 47, the stepped portion 48, the pushing portion 50, the groove portion 51, the unlocking slope 52, etc., the latch mechanism 44 is A simple configuration consisting of protrusions, holes (holes) and the like is sufficient.

  (5) The lock device 19 is electrically driven by a lock motor 29. Therefore, since switching between lock and unlock can be performed automatically, convenience can be ensured.

  (6) One lock pin 25 that can be switched between the lock position and the unlock position by the lock motor 29 is a common part for both the charging cable lock and the lid lock. Therefore, since it is not necessary to provide the lock pin 25 and the lock motor 29 for each of the charging cable lock and the lid lock, the structure of the lock device 19 can be simplified.

  (7) When locking, the surface of the lid box 5 with which the lock pin 25 abuts is used as the strength receiving surface 39. For this reason, even when an external force in the unlocking direction is applied to the lock pin 25 at the time of locking, this force can be supported by the strength receiving surface 39, so that the lock pin 25 is improperly moved in the unlocking direction. It is difficult for the situation to occur. For this reason, the effect of preventing unauthorized unlocking of the lock device 19 is enhanced.

  (8) A pull cord 56 is attached to the lock stopper 27, and a lock forcibly releasing mechanism 54 that allows the lock state of the lock device 19 to be manually forcibly released is provided. Therefore, at the time of locking, for example, even if the lock motor 29 or its peripheral circuit breaks down, the lock can be forcibly released by pulling the pull cord 56 and manually pulling the lock stopper 27 in the unlocking direction.
