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.

  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.

[Outline 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.

  The lid box 5 is provided with a transmission antenna 23 capable of transmitting radio waves to the electronic key 22 according to an electronic key system that performs key authentication wirelessly. The electronic key system is a key operation free system that performs ID collation with the electronic key 22 and narrow-band radio (communication distance: several meters), for example, triggered by communication from the vehicle. If the verification is established, the door locking / unlocking operation is permitted / executed, and if the in-vehicle electronic key 22 and ID verification (in-vehicle smart verification) are established, the vehicle power supply transition operation is permitted. The transmission antenna 23 is used to confirm whether or not the electronic key 22 is near the power supply port 2. A smart verification start trigger (request signal Srq) is transmitted in the vicinity of the power supply port 2 in the LF (Low Frequency) band. It can be transmitted by radio waves. The establishment result of the smart collation triggered by the radio wave of the transmission antenna 23 is used as one condition for permitting the lid 3 opening operation, for example.

  As shown in FIGS. 3 and 4 (a), 4 (b), a lock pin 25 that can be locked to the lid 3 or the power supply plug 11 is provided inside the housing 24 of the lock device 19 in the longitudinal direction (see FIG. 3 in the Z-axis direction). Between the inner wall of the housing 24 and the lock pin 25, an urging member 26 that constantly urges the lock pin 25 in the lock direction (the arrow Z1 direction in FIG. 3) is provided. That is, the lock device 19 of this example is a lock side constant bias type in which the lock pin 25 is always biased to the lock side by the bias member 26. As the urging member 26, for example, a coil spring is used. The lock pin 25 corresponds to a lock member.

  The lock pin 25 has a substantially pin shape having a large-diameter head portion 27 and a shaft portion 28 having a smaller diameter than the head portion 27. The lock pin 25 is prevented from coming off when the head portion 27 is hooked on the stepped portion 29 in the housing 24. The lock pin 25 normally takes a protruding position where the head 27 is pressed against the stepped portion 29 by the urging force of the urging member 26.

  The lock device 19 is provided with a link member 30 that switches between fixing and non-fixing of the lock pin 25 so as to be able to reciprocate along its own longitudinal direction (Y-axis direction in FIG. 3). It is connected to a lock motor 32 via a piece 31. The motor shaft of the lock motor 32 is connected to the rotating piece 31 via the worm gear 33. The worm gear 33 includes a worm 34 disposed on the motor shaft and a worm wheel 35 disposed in the center of the rotating piece 31. The lock motor 32 corresponds to an actuator.

  A pinion 36 that rotates integrally on the same axis as the rotation piece 31 is provided at the end of the shaft portion 31 a of the rotation piece 31, and the link member 30 is connected to the pinion 36. The link member 30 includes a rack 37 that meshes with the pinion 36, a locking pin 38 that is fitted to the rack 37, and a biasing member 39 that is interposed between the rack 37 and the locking pin 38. As the urging member 39, for example, a coil spring is used. The rack 37 and the locking pin 38 are connected by, for example, the structure of the protrusion 40 and the long hole 41 (see FIGS. 4A and 4B). The rotating piece 31 is rotated around the axis L1 of the substantially cylindrical shaft portion 31a by the driving force of the lock motor 32. As the turning piece 31 rotates, the link member 30 slides in a direction (Y-axis direction in FIG. 3) perpendicular to the moving direction of the lock pin 25 (Z-axis direction in FIG. 3).

  On the side surface of the head portion 27 of the lock pin 25, a groove portion 42 into which the lock pin 38 can be fitted and locked is recessed. When the locking pin 38 is locked in the groove portion 42, the operation of the lock pin 25 in the vertical direction (Z-axis direction in FIG. 3) becomes impossible. Further, a guide slope 43 is formed on the side surface of the head portion 27 to guide the fitting of the locking pin 38 into the groove portion 42. That is, when the locking pin 38 and the groove 42 are not aligned and the locking pin 38 contacts the guide slope 43, the locking pin 38 presses against the guide slope 43 by the biasing force of the biasing member 39. Thus, the fitting of the locking pin 38 into the groove 42 is guided.

  As shown in FIG. 4A, when the link member 30 is slid in the unlocking direction (in the direction of arrow Y2 in FIG. 4A) by one-way rotation of the lock motor 32, the locking pin 38 is locked. It separates from the 25 groove portions 42. Thereby, the lock pin 25 is not fixed, and the reciprocating motion in the vertical direction is possible while receiving the biasing force in the locking direction by the biasing member 26. Therefore, the lock device 19 takes a state in which the movement of the lock pin 25 is permitted, that is, an unlocked state.

  On the other hand, as shown in FIG. 4B, when the link member 30 slides in the locking direction (in the direction of arrow Y1 in FIG. 4B) due to the rotation of the lock motor 32 in the other direction, the locking pin 38 is locked. Locks in the groove 42 of the pin 25. Thereby, since the lock pin 25 is fixed, it cannot move up and down. Therefore, the locking device 19 takes a state where the lock pin 25 is fixed at the locked position, that is, a locked state.

[Switch structure of locking device]
As shown in FIGS. 5A and 5B, a minute stroke W having a predetermined gap is provided between the lock pin 25 and the locking pin 38. The slight stroke W is a slight rotation operation to the opening side of the lock arm 13 while maintaining the locking (holding margin) between the lock arm 13 and the locking protrusion 17 when the lock pin 25 is in the locked state. It is a gap for allowing For the minute stroke W, an existing gap may be used as it is, or it may be newly provided.

  Between the inner wall of the housing 24 of the locking device 19 and the lock pin 25, there is provided a sliding contact 44 for switching the contact state when the lock pin 25 is moved by a minute stroke W. The sliding contact 44 has a fixed contact 45 disposed on the inner wall surface of the housing 24 and a movable contact 46 disposed on the lock pin 25. When the lock pin 25 is in the locked state, if the normal protruding position is taken without being pushed up by the lock arm 13, the sliding contact 44 is turned on (state in FIG. 5A), and the lock arm 13 makes a small stroke W. When pushed up by a minute, the sliding contact 44 is turned off (state shown in FIG. 5B). The sliding contact 44 corresponds to the detection unit and the contacted unit.

[Electrical configuration of the locking device]
As shown in FIG. 7, the lock device 19 is provided with a lock ECU (Electronic Control Unit) 47 that controls the lock / unlock operation of the lock device 19. The lock ECU 47 is connected to the lock motor 32 and the sliding contact 44 and also receives a plug connection detection signal. The lock ECU 47 is connected to a lock state detection unit 48 that detects whether the lock device 19 is locked or unlocked. As the lock state detection unit 48, for example, sensors disposed at the lock position and the unlock position of the locking pin 38, an encoder that detects the rotation direction and the rotation amount of the lock motor 32, and the like are used. The lock ECU 47 corresponds to the control means.

  The lock ECU 47 is connected to a verification ECU 49 that performs authentication in the electronic key system. In the memory (not shown) of the verification ECU 49, the ID code of the electronic key 22 registered in the vehicle is written and stored. The verification ECU 49 is connected to the transmission antenna 23 described above and a vehicle receiver 50 capable of receiving radio waves in the UHF (Ultra High Frequency) band. The verification ECU 49 can perform smart verification periodically or at a predetermined timing, and can output a verification result to the lock ECU 47. The verification ECU 49 corresponds to an authentication unit.

Next, operation | movement of the locking device 19 of this example is demonstrated using FIGS.
[Charging cable unlocking operation]
As shown in FIG. 7, when the charging cable block is in the locked state, the locking pin 38 fits into the groove 42 of the lock pin 25 and contacts the contact surface 51 of the upper surface of the claw portion 14 of the lock arm 13. Is fixed. Therefore, since the lock pin 25 pushes and locks the lock arm 13 from above, it cannot be operated even if the lock arm 13 is opened, and the lock state of the charging cable lock is maintained.

  When the power supply plug 11 is gripped in order to pull out the charging cable 9 from the inlet 6, the arm operation unit 15 is pushed. At this time, the lock arm 13 rotates to the open side, and the lock pin 25 pushes the lock pin 25 upward (in the direction of arrow Z2 in FIG. 7) by a minute stroke W from the protruding position. As a result, the sliding contact 44 is switched from on to off, and the lock ECU 47 inputs an off signal from the sliding contact 44 in place of the on signal. When the lock ECU 47 receives an off signal from the sliding contact 44, the lock ECU 47 outputs a smart verification start request to the verification ECU 49.

  When the verification ECU 49 receives a smart verification start request from the lock ECU 47, the verification ECU 49 starts transmitting the request signal Srq from the transmission antenna 23. At this time, if the electronic key 22 is in the vicinity of the power feeding port 2, communication between the electronic key 22 and the transmission antenna 23 is established. When receiving the request signal Srq, the electronic key 22 returns an ID signal Sid including the ID code registered in the electronic key 22 to the vehicle body 1. When the vehicle receiver 50 receives the ID signal Sid transmitted from the electronic key 22, the verification ECU 49 confirms the validity of the ID code in the ID signal Sid. When the verification ECU 49 confirms that the ID code is correct, the verification ECU 49 recognizes that smart verification is established, and outputs a smart verification establishment notification to the lock ECU 47.

  The lock ECU 47 rotates the lock motor 32 in the unlocking direction when a smart collation establishment notification is input from the collation ECU 49 in a situation where it is determined that the lock is based on the detection signal of the lock state detection unit 48. As a result, the locking pin 38 slides in the unlocking direction (in the direction of arrow Y2 in FIG. 7) and retracts from the groove portion 42, so that the locking pin 25 becomes free and the charging cable lock is unlocked. Therefore, the lock arm 13 can be further rotated to the opening side, and the charging cable 9 can be pulled out from the inlet 6.

  When the charging cable 9 is pulled out from the inlet 6, the lock pin 25 slides downward (in the direction of arrow Z <b> 1 in FIG. 7) by the biasing force of the biasing member 26. At this time, the lock pin 25 is lowered until the head portion 27 comes into contact with the stepped portion 29 and returns to the original protruding position. When the lock pin 25 returns to the normal protruding position, the sliding contact 44 also returns to the on state.

[Charging cable lock operation]
As shown in FIG. 8, when the charging cable 9 is inserted into the inlet 6, the lock pin 25 is lifted upward (in the direction of arrow Z <b> 2 in FIG. 8) by the lock arm 13. At this time, the sliding contact 44 is switched from on to off, and the lock ECU 47 inputs an off signal from the sliding contact 44. When the lock ECU 47 receives an OFF signal instead of the ON signal from the sliding contact 44, the lock ECU 47 outputs a smart verification start request to the verification ECU 49.

  When the verification ECU 49 receives a smart verification start request from the lock ECU 47, the verification ECU 49 starts smart verification as in the case of unlocking the charging cable. That is, the request signal Srq is transmitted from the transmission antenna 23, the ID signal Sid is returned to the electronic key 22, and the validity of the electronic key 22 is confirmed by the ID signal Sid. When the collation ECU 49 confirms that smart collation is established, the collation ECU 49 outputs a smart collation establishment notification to the lock ECU 47.

  The lock ECU 47 rotates the lock motor 32 in the lock direction when a smart collation establishment notification is input from the collation ECU 49 in a situation where it is determined that the lock is unlocked based on the detection signal of the lock state detection unit 48. As a result, the locking pin 38 slides in the locking direction (the direction of the arrow Y1 in FIG. 8) and tries to enter the groove 42 of the locking pin 25. At this time, if the lock pin 25 is greatly lifted upward, the locking pin 38 comes into contact with the guide slope 43 and waits for locking to the groove 42. As the claw portion 14 is engaged with the engagement protrusion 17, the lock pin 25 is slid downward (in the direction of arrow Z1 in FIG. 8) by the urging force of the urging member 26, and the engagement pin 38 is moved. It finally fits into the groove part 42 while going up the guide slope 43. Therefore, the lock pin 25 that comes into contact with the abutment surface 51 is fixed by the locking pin 38, so that the lock arm 13 cannot be rotated to the open side. For this reason, the charging cable lock is switched to the locked state, and the charging cable 9 connected to the inlet 6 is not illegally pulled out by a third party or the like.

When the lock pin 25 is in the fixed state, it returns to the original protruding position. When the lock pin 25 returns to the normal protruding position, the sliding contact 44 also returns to the on state.
[Lid unlock operation]
As shown in FIG. 9, the structure of the charging cable unlocking can also be applied to the lid unlocking. In this case, the lid 3 can be pushed one step further from the closed position. In addition, a pressing slope 52 is set on the inner surface of the locking groove 21, and the locking slope 25 can lift the lock pin 25 at the lock position upward (in the direction of arrow Z2 in FIG. 9) by a minute stroke W. Keep it as

  When the lid 3 is opened, when the lid 3 is pushed, the pushing slope 52 of the striker 20 pushes the lock pin 25 upward (in the direction of arrow Z2 in FIG. 9), and the sliding contact 44 is switched from on to off. Change. When the lock ECU 47 inputs an OFF signal instead of the ON signal from the sliding contact 44, the lock ECU 47 outputs a smart verification start request to the verification ECU 49, and causes the verification ECU 49 to execute smart verification. When the lock ECU 47 receives a smart collation establishment notification from the collation ECU 49 in a situation where it is determined that the lock is based on the detection signal of the lock state detection unit 48, the lock ECU 32 rotates the lock motor 32 in the unlocking direction, and the lid lock Is unlocked. Thereby, the lid 3 is unlocked and the opening operation of the lid 3 is permitted.

[Lidlock operation]
As shown in FIG. 10, the structure of the charging cable lock can be applied to a lid lock. When closing the lid, the pushing slope 53 at the tip of the striker 20 pushes the lock pin 25 upward (in the direction of arrow Z2 in FIG. 10), and the sliding contact 44 is switched from on to off. Therefore, similarly to the charging cable lock, smart verification is executed, and if smart verification is established, the lock motor 32 is rotated in the locking direction, and the lid lock is switched to the locked state. Therefore, the lid 3 is locked in the closed state, and unauthorized opening operation is prevented.

According to the configuration of the present embodiment, the following effects can be obtained.
(1) When pulling out the charging cable 9 from the inlet 6, when the lock arm 13 is turned to remove the claw fitting, the lock pin 25 is lifted by the lock arm 13 by a minute stroke W, and the sliding contact 44 is Turned off. When the sliding contact 44 is turned from on to off, the smart collation is triggered by this, and when the smart collation is established, the charging cable lock is switched to unlock and the charging cable 9 is pulled out from the inlet 6. Therefore, when removing the charging cable 9, the charging cable 11 is switched to unlocking in the process of a series of operations of holding the power supply plug 11 and rotating the lock arm 13 to the open side and pulling out the charging cable 9 from the inlet 6. Therefore, the convenience of pulling out the charging cable 9 can be improved.

  (2) Since the lock / unlock switching using the minute stroke W is also applied to the charge cable lock and the lid lock / unlock, the convenience of the lid 3 opening and closing and the charge cable lock can be secured.

(3) Since the minute stroke W is detected by the sliding contact 44, if such a contact portion is used, the component cost can be reduced.
(4) Since the smart verification is included in the lock / unlock switching start condition, only the authorized user can be permitted to switch the lock / unlock.

  (5) One lock pin 25 that is switched between the lock position and the unlock position by the lock motor 32 is a shared part of the charging cable lock and the lid lock. Therefore, since it is not necessary to provide the lock pin 25 and the lock motor 32 for each of the charging cable lock and the lid lock, the structure of the lock device 19 can be simplified.

Note that the embodiment is not limited to the configuration described so far, and may be modified as follows.
-The lock / unlock start condition is not limited to the smart verification that is triggered by the detection of OFF at the sliding contact 44, and various patterns are adopted, for example, the door lock state of the vehicle door is one condition. Is possible.

The electronic key system may be, for example, a wireless key system or a short-range wireless communication system. The wireless key system is a system that performs key authentication by narrowband radio in response to communication from the electronic key 22. The short-range wireless communication system is a system that performs two-way authentication using short-range wireless (communication distance: several centimeters to several tens of centimeters), such as an immobilizer system or an NFC (Near Field Communication) system.

-You may make it identify whether the charging cable 9 is connected to the inlet 6 using the detection signal of the plug connection detection part 18. FIG.
The lid 3 may be opened and closed by manually opening the lid in the closed position with a finger or the like after unlocking the lid.

The lid 3 may be configured to be opened and closed by a push lifter instead of a torsion spring.

The plug connection detection unit 18 may be a switch or sensor disposed on the inlet 6 side. Further, the plug connection detection unit 18 may be either a contact point or a non-contact point.
The locking point of the lock pin 25 when the lid is locked may be a place other than the striker 20.

-The attachment position of the locking device 19 is not limited to the upper part of the lid box 5, For example, it can change to other positions, such as a side part.
The locking device 19 may be attached to the lid box 5 by being fastened together with the inlet 6, or may be individually attached to the lid box 5 regardless of the inlet 6.

The locking device 19 may be, for example, one of locking / unlocking being manual and the other being electric.
The locking device 19 may be dedicated to the charging cable lock or dedicated to the lid lock. Moreover, the locking device 19 should just be arrange | positioned in the electric power feeding port 2 in a broad sense.

The lock device 19 can be appropriately changed to another structure as long as the lock pin 25 can be moved in each direction of locking / unlocking. For example, the lock member is not limited to a pin that slides and may be, for example, a notch formed in a rotating columnar member. In this case, the lock arm 13 is fixed at a position where there is no notch, and the operation of the lock arm 13 is allowed at the notch. Further, the lock member may be a fan-shaped plate that rotates to each of the lock / unlock positions.

The lock device 19 may have a structure in which the lock pin 25 is locked by, for example, directly locking the lock pin 25 to the casing (main body portion) of the power supply plug 11.
-Various contact switches and contactless sensors can be used for the detection unit.

As the attachment position of the detection unit, various positions can be adopted as long as the lifting of the lock pin 25 can be detected.
