Description

  The present invention relates to a lock manual release structure of a power supply plug lock device that is provided in a power receiving connector that is connected to a power supply plug that is a power supply source and charges a battery and that locks the power supply plug to prevent it from coming off.

  In recent years, for the purpose of suppressing exhaust gas from vehicles to a small extent, each vehicle manufacturer has become very high in the development of electric vehicles (including hybrid vehicles) driven by motors. In such an electric vehicle, each time the remaining amount of power of the battery, which is a power source of the vehicle, decreases, the battery must be charged at, for example, a home or a desk lamp. However, various charging systems that can be handled easily will be provided (for example, see Patent Document 1). As an example of this case, for example, an inlet part to which a power supply connector (power supply plug) connected to a commercial power supply at home can be connected is provided in the vehicle, and the power supply connector is connected to the inlet part of the parked vehicle when returning home. It is assumed that the battery of the vehicle is charged by sending the battery to the vehicle.

  Even though it is said that rapid charging technology has been developed for battery charging of electric vehicles, there is a current situation that requires a relatively long time compared to gasoline supply of gasoline vehicles. In particular, when a user charges a battery at home, it is rare that a general household is equipped with a device for high-speed charging. Therefore, charging is performed by connecting a power supply connector connected to a household power supply to the inlet of the vehicle. In many cases, the vehicle is left in that state for a long time after the start. In this case, for example, there is a possibility that the power feeding connector is removed from the vehicle being fed and mounted on the inlet portion of another vehicle to be stolen, or the power feeding connector itself may be stolen.

  Therefore, in order to prevent the power supply connector from being illegally removed from the inlet portion, for example, it is assumed that a lock device that locks the connection state between the power supply connector and the inlet portion is mounted on the power supply connector. As an example of this locking device, a lock bar that can reciprocate using a motor as a drive source is provided, and when the locking claw of the power feeding connector is engaged with the engaging portion of the inlet portion, the lock bar is positioned at the locking position. Then, the movement of the locking claw is fixed with this lock bar. As a result, the locking device is locked and the inlet portion cannot be pulled out from the power supply connector. When removing the power feeding connector from the inlet portion, the lock device is unlocked by positioning the lock bar at the unlock position and releasing the movement of the latching claw.

(First embodiment)
Hereinafter, a first embodiment in which the present invention is embodied in a power receiving connector of a plug-in hybrid vehicle will be described with reference to FIGS.

  As shown in FIG. 1, a hybrid vehicle 1 is provided with a hybrid system 3 that outputs a combination of driving forces of an engine and a motor as a driving source for driving wheels 2. The hybrid system 3 has a mode in which only the engine power is mechanically transmitted to the drive wheels 2, a mode in which power is generated by the engine power and a motor is driven, and the drive wheels 2 are directly driven by both the engine and the motor. The vehicle can be driven in various modes, ie, a driving mode and a mode in which only the motor is driven without using the engine.

  The hybrid system 3 is connected to a battery 4 that supplies electric power to the motor. The battery 4 can charge the battery 4 not only with the power generated by the engine power but also with the night power from an external power source 61 of the vehicle 1, for example, a household outlet. For this reason, the plug-in hybrid vehicle 1 can travel a longer distance than a conventional hybrid vehicle using only a motor, and the engine operation amount is reduced because it is not necessary to operate the engine for charging. It is possible.

  The vehicle 1 is equipped with an electronic key system capable of performing vehicle operations such as door locking / unlocking without the driver actually operating the vehicle key. In the electronic key system 70, an electronic key 80 capable of transmitting a key-specific ID code by wireless communication is used as a vehicle key. The electronic key system 70 transmits a request signal Srq from the vehicle 1 as an ID code reply request. When the electronic key 80 receives the request signal Srq, the electronic key 80 includes its own ID code in response to the request signal Srq. In this system, the ID code signal Sid is returned to the vehicle 1 by the narrow-band wireless communication, and when the ID code of the electronic key 80 matches the ID code of the vehicle 1, the door lock is unlocked or executed.

  The electronic key system 70 will be described below. The vehicle 1 is provided with a verification ECU (Electronic Control Unit) 71 as verification means for performing ID verification when performing narrow-area wireless communication with the electronic key 80. Yes. The verification ECU 71 includes an outside LF transmitter 72 embedded in each door of the vehicle 1 and capable of transmitting an LF (Low Frequency) band signal outside the vehicle, and an LF band radio signal embedded under the vehicle floor and the like inside the vehicle.

The verification ECU 71 includes a memory 71a in which an ID code is stored as a unique key code.

  On the other hand, the electronic key 80 is provided with a communication control unit 81 as a control unit for performing wireless communication with the vehicle 1 according to the electronic key system 70. The communication control unit 81 includes a memory 81a in which an ID code is stored as a unique key code. The communication control unit 81 is connected to an LF receiving unit 82 capable of receiving an LF band signal transmitted externally and a UHF transmission unit 83 capable of transmitting a UHF band signal in accordance with a command from the communication control unit 81. Yes.

  The verification ECU 71 intermittently transmits an LF band request signal Srq from the outside LF transmitter 72 to form a communication area around the vehicle 1. When the electronic key 80 enters this communication area and receives the request signal Srq by the LF receiver 82, the electronic key 80 responds to the request signal Srq and includes the UHF including the ID code registered in its own memory 81a. A band ID code signal Sid is returned from the UHF transmitter 83. When the UHF receiver 74 receives the ID code signal Sid, the verification ECU 71 compares the ID code registered in its own memory 71a with the ID code of the electronic key 80 and performs ID verification (external vehicle verification). When the verification outside the vehicle is established, the verification ECU 71 permits or executes door locking / unlocking by a door lock device (not shown).

  When the verification ECU 71 recognizes that the driver has boarded by opening the door after the outside verification is established and the door lock is unlocked, the verification ECU 71 transmits a request signal Srq from the in-vehicle LF transmitter 73 in this time. An in-vehicle communication area is formed throughout. When the UHF receiver 74 receives the ID code signal Sid returned by the electronic key 80 entering the in-vehicle communication area, the verification ECU 71 receives the ID code registered in its own memory 71a and the ID code of the electronic key 80. In comparison, ID verification (in-vehicle verification) is performed. The verification ECU 71 permits the start of the hybrid system 3 when the in-vehicle verification is established.

  The plug-in hybrid vehicle 1 can charge the battery 4 by a plug-in vehicle battery charging system 60 shown in FIG. In this case, the charging system 60 is provided with a power supply plug 10 that charges the battery 4 of the vehicle 1 in, for example, a house or a desk lamp. The power supply plug 10 is connected to an AC (commercial power) 200 V as an external power supply 61 via the cable 12. The cable 12 is provided with a charge on / off switch 62 that is operated when charging is started.

The inlet part 20 is a connector part into which the power supply plug 10 is inserted, and is mounted on the front left side of the vehicle body, for example, like a fueling port of a gasoline vehicle. The inlet unit 20 converts the AC voltage sent from the power supply plug 10 into a DC voltage by the converter 5 and sends it to the battery 4 of the vehicle 1 to charge the battery 4 with electric power. The inlet portion 20 can be charged when the power supply plug 10 is fitted to the inlet portion 20 and authentication of a key carried by the user is established. Here, the authentication of the key is performed by collating the ID code with the electronic key. The outside communication area is formed over the entire vehicle periphery, and the key inquiry (transmission of the request signal Srq) from the vehicle 1 is always executed as polling, so the user has a key in front of the inlet unit 20. If it stands, ID collation will be performed without a problem.

  The charging system 60 can be charged on condition that the ID verification is established by the electronic key system 70 and the power plug 10 is connected to the inlet unit 20. In this case, the vehicle 1 is provided with a charging ECU 75 as a control means for performing control related to charging. The charging ECU 75 can communicate with the verification ECU 71 via a not-shown in-vehicle LAN (Local Area Network), and the verification ECU 71 can check the result of ID verification.

  Further, the charging ECU 75 is connected to the detection sensor 40 and the motor 22 as detection means provided in the lock device 30 of the inlet portion 20. The detection sensor 40 monitors whether or not the locking claw 16 is engaged with the engaging portion 21, and when detecting that the locking claw 16 is locked to the engaging portion 21, sends a detection signal to the charging ECU 75. Output. When the charging ECU 75 confirms that ID verification is established and that the locking claw 16 is engaged with the engaging portion 21, the charging ECU 75 switches the lock device 30 to the locked state and executes the charging operation.

  In addition, the charging system 60 can remove the power plug 10 from the inlet portion 20 on the condition that the ID verification is established by the electronic key system 70 and the removal switch 76 provided in the vehicle 1 is operated. To do. In this case, the vehicle 1 is provided with a removal switch 76 that is operated when removing the power supply plug 10, and an operation signal is output to the charging ECU 75 when operated. When the charging ECU 75 confirms that the ID verification is established and that the removal switch 76 is operated, the charging ECU 75 switches the lock device 30 to the unlocked state and permits the removal of the power supply plug 10. The verification ECU 71 permits the hybrid system 3 to start on the condition that the power supply plug 10 is removed from the inlet portion 20 and that the in-vehicle verification is established.

  As shown in FIG. 2, the cable 12 connected to the charging device 62 is connected to the base end 11 a of the main body 11 of the power supply plug 10. The main body 11 of the power supply plug 10 is formed with a grip portion 13 that is held by a user. A cylindrical fitting portion 14 to be fitted to the inlet portion 20 is provided at the tip 11 b of the main body 11 of the power supply plug 10.

  An engaging claw 16 is provided on the upper portion of the fitting portion 14 to hold the inserted state when the power supply plug 10 is inserted into the inlet portion 20. When the locking claw 16 is engaged with the inlet portion 20 (solid line in the figure), the locking claw 16 is in a state of holding the power plug 10 in the inlet portion 20 so that the locking claw 16 opens from the fitting portion 14. When the state of tilting in the direction (two-dot chain line in the figure) is taken, the power supply plug 10 can be removed from the inlet portion 20. The locking claw 16 is in a closed state in a normal state, and can be operated in an open state by pressing the operation portion 17 on the upper side of the grip portion 13 of the main body 11.

  As shown in FIG. 3, a connection terminal 29 is provided inside the inlet portion 20 as a connection destination of the connection terminal 15 provided in the fitting portion 14 of the power supply plug 10. The connection terminal 29 includes a power terminal serving as a power transmission path, a control terminal serving as a communication path for various control commands, and the like. On the outer peripheral surface upper portion 20 a of the inlet portion 20, an engaging portion 21 is formed that engages with the locking claw 16 of the power supply plug 10 and maintains the engagement state between the power supply plug 10 and the inlet portion 20. The engaging portion 21 includes an engaging convex portion 21b that engages the engaging claw 16 with an engaging space 21a in which the engaging claw 16 is inserted.

  As shown in FIGS. 4 to 11, a locking device 30 that switches between a locked state and an unlocked state of the locking claw 16 engaged with the engaging portion 21 is fixed to the upper portion of the inlet portion 20. In the lock device 30 of this example, when the transmission member (shaft with gear) 25 is rotated by the driving force of the motor 22 as the driving means, the rotational motion of the transmission member 25 is converted into the linear motion of the stopper 26 as the stopper portion. As a result of the linear movement of the stopper 26, the lock bar 23 as a restricting member is positioned above the locking claw 16 to bring the locking claw 16 into a locked state. The locked state refers to a state where the locking claw 16 cannot be opened.

The motor 22 is fixed to the motor housing portion 32 a by two screws 36. The drive shaft 22a of the motor 22 is inserted into a through hole 32d formed in the partition wall 32c and protrudes from the member housing portion 32b. A cylindrical transmission member 25 is fixed to the drive shaft 22a of the motor 22 so as to rotate integrally with the drive shaft 22a. One end of the transmission member 25 is pivotally supported by the through hole 32d via the buffer member 24. The other end of the transmission member 25 is pivotally supported by a bearing portion 34 a formed on the second lid portion 34. On the outer periphery of the transmission member 25, a male screw portion 25a having a screw groove cut along the circumferential direction is formed.

  A stopper 26 that contacts the lock bar 23 and displaces the lock bar 23 is screwed to the transmission member 25. A through hole is formed in the central portion of the stopper 26 in the axial direction of the transmission member 25, and a female screw portion 26a into which the male screw portion 25a of the transmission member 25 is screwed is formed in the through hole. That is, the transmission member 25 is integrally assembled by screwing its own male screw portion 25 a with the female screw portion 26 a of the stopper 26. As a result, when the transmission member 25 is rotated by the motor 22, the male screw portion 25 a of the transmission member 25 rotates in the female screw portion 26 a of the stopper 26, and the stopper 26 is linear in the axial direction of the transmission member 25. Moving. The stopper 26 has two positions: a lock position (regulation position) where the lock bar 23 restricts the displacement of the locking claw 16 and an unlock position (non-regulation position) where the lock bar 23 does not restrict the displacement of the locking claw 16. Between them. That is, the male screw portion 25a of the transmission member 25 and the female screw portion 26a of the stopper 26 function as a conversion mechanism.

  On the left side of the stopper 26, a magnet housing portion 26b for housing a magnet 27 for detecting the position of the stopper 26 is formed. The magnet housing portion 26b is formed so as to protrude vertically and horizontally with respect to the displacement direction of the stopper 26. A first Hall element 38 and a second Hall element 39 are installed on the substrate 37 attached to the inner surface of the second lid portion 34 at a position facing the magnet 27.

The manual release held state is maintained. Then, when the push operation portion 54 is pushed in again from this position, the pin lock 56 is detached from the groove portion 55c, is guided to the inner wall of the cam groove 55a, and returns to the original position. The cam groove 55a and the heart cam portion 55b function as a heart cam groove.

  The manual release holding mechanism 53 is connected to the lock bar 23 via the link 52. In the case of this example, a guide member 51 having a U-shaped loose fitting portion 51 a is projected from the side surface of the lock bar 23. One end of the link 52 is attached and fixed to the movable portion 55, and the other end is loosely fitted to the loose fitting portion 51 a of the lock bar 23. When the lock manual release mechanism 50 is not used, the loosely fitting portion 51a is configured such that the link 52 contacts the left inner wall when the lock bar 23 is locked, and the link 52 contacts the right inner wall when the lock bar 23 is unlocked. Is formed. The guide member 51 protrudes outside from a through hole 59 formed in the main body 32. The through hole 59 is formed so as to include a moving range in which the guiding member 51 does not collide even when the guiding member 51 moves.

  As shown in FIG. 9, when the push operation portion 54 is pushed, the movable portion 55 moves to the left in the figure, and as the movable portion 55 moves, the pin lock 56 is guided to the cam groove 55a, It moves relative to the heart cam portion 55b from the left side to the right side as indicated by the arrows in the figure. Then, as shown in FIG. 10, when the movable portion 55 moves to the back of the case 57, the pin lock 56 is engaged with the groove portion 55 c of the heart cam portion 55 b, and this position state is changed by the urging force of the urging spring 58. The push state of the push operation unit 54 is held. When the movable portion 55 moves to the back, the movement of the movable portion 55 is transmitted to the lock bar 23 via the link 52, and the loose fitting portion 51a is pushed to the back by the link 52, so that the lock bar 23 is moved from the lock position. The position is manually switched to the unlock position. That is, the lock manual release mechanism 50 takes the manual release holding state.

  When the lock manual release mechanism 50 takes the manual release hold state, when the push operation unit 54 is pushed again, this time, the movable unit 55 returns to the original position pushed up by the urging spring 58. At this time, since the position restriction of the lock bar 23 due to the pushing of the link 52 is released, the lock bar 23 is moved back to the original lock position by the biasing force of the spring 28. That is, the lock manual release mechanism 50 is in an original normal state where manual release is not effective. As a result, when the lock bar 23 is driven normally, the lock bar 23 is moved by driving the motor 22.

  When the push operating portion 54 is pushed when the lock device 30 is in the locked state, even if the lock bar 23 is in the locked position by the stopper 26, the lock position side is not obstructed by the stopper 26 by the buffer hole 23a. And is held at the lock position by the manual release holding mechanism 53. At this time, the spring 28 provided between the lock bar 23 and the second lid portion 34 and the biasing spring 58 provided between the movable portion 55 and the case 57 contract. Then, when the push operation portion 54 is pushed, the lock bar 23 is moved to the unlock position side by the urging force of the contracted springs 28 and 58.

  Here, since the push operation unit 54 is provided in the vehicle, it cannot be operated unless the user unlocks the door with the electronic key 80 and gets into the vehicle. That is, only the user of the vehicle 1 can perform this manual lock release.

  Next, assembly of the locking device 30 will be described with reference to FIG. The lock device 30 is assembled by being assembled in the longitudinal direction of the main body 32 except for the first lid portion 33.

  First, the motor 22 is inserted into the motor housing portion 32a along the longitudinal direction of the main body 32, the drive shaft 22a is inserted into the through hole 32d of the partition wall 32c, and is housed in a state protruding from the member housing portion 32b. The motor 22 is screwed by screws 36, 36 from the member housing portion 32b side, and the motor 22 is fixed to the motor housing portion 32a. Subsequently, the buffer member 24 is mounted between the drive shaft 22a and the through hole 32d from the member housing portion 32b side.

  Subsequently, the magnet 27 is accommodated by being inserted into the magnet accommodating portion 26 b of the stopper 26. The male screw portion 25 a of the transmission member 25 is screwed into the female screw portion 26 a of the stopper 26. Further, the lower rail protrusion 26d of the stopper 26 to which the transmission member 25 is screwed is inserted into the buffer hole 23a of the lock bar 23, and the recess 26e of the lower rail protrusion 26d is brought into contact with the inner wall of the buffer hole 23a. A guide member 51 is fixed to the side of the lock bar 23.

  Then, the assembled transmission member 25, stopper 26, and lock bar 23 are inserted into the member accommodating portion 32b along the longitudinal direction of the main body 32. At this time, the transmission member 25 is fixed to the drive shaft 22a. A buffer member 24 is sandwiched between the end of the transmission member 25 and the partition wall 32c. The lock bar 23 is fitted in the lock bar guide groove 32 g of the main body 32, and the lower rail protrusion 26 d of the stopper 26 is fitted in the stopper lower rail groove 32 f of the main body 32. At this time, the guide member 51 protrudes from the through hole 59 to the outside. Then, the link 52 is loosely fitted to the loosely fitting portion 51 a of the guide member 51.

Then, the second lid 34 is attached to the main body 32. At this time, the other end of the spring 28 is inserted into the recess 34 b of the second lid 34.
Subsequently, the substrate 37 on which the first Hall element 38 and the second Hall element 39 are mounted is fixed to the first lid portion 33. The substrate 37 is electrically connected to the motor 22 and is connected to a connection connector 35. The first lid 33 is attached to the main body 32. Therefore, the locking device 30 is assembled.

Next, an operation performed when the battery 4 is charged by the power supply plug 10 and an operation of the lock device 30 will be described with reference to FIGS.
First, as shown by a two-dot chain line in FIG. 2, by pushing the operation portion 17, the latching claw 16 is opened to be separated from the fitting portion 14. Then, as shown in FIGS. 5 and 6, the locking claw 16 is positioned so as to enter the engagement space 21 a of the engagement portion 21, and the power supply plug 10 is moved along the axial direction in that state. Then, the power supply plug 10 is inserted into the inlet part 20 to the back, and is connected to the connection terminal 15 on the power supply side and the connection terminal 29 of the inlet part 20. At this time, the locking claw 16 is positioned above the engaging convex portion 21b of the engaging portion 21 (two-dot chain line in the figure).

  Then, when the hand is released from the operation unit 17 in this state, the locking claw 16 takes a closing motion, and the locking claw 16 engages with the engaging convex portion 21b (solid line in the figure). As a result, the power supply plug 10 is engaged with the inlet portion 20. And if the detection sensor 40 detects that the latching claw 16 engaged with the engagement convex part 21b, it will output a detection signal to charge ECU75. When the detection signal is input from the detection sensor 40, the charging ECU 75 sets a locking claw detection flag in the memory 75a. When the charging ECU 75 confirms that the ID verification establishment flag is set in the memory 75a and the locking claw detection flag is set, the charging ECU 75 outputs a drive signal to the motor 22 and starts the locking operation of the locking claw 16. To do.

  At this time, when the motor 22 is driven, the transmission member 25 is rotated by this driving force. The rotational movement of the transmission member 25 is converted into a rectilinear movement in the longitudinal direction of the main body case 31 of the stopper 26 by screwing between the male screw part 25a of the transmission member 25 and the female screw part 26a of the stopper 26. Therefore, the stopper 26 starts a straight movement toward the motor 22 side of the main body case 31, that is, the lock side. At this time, the lock bar 23 moves linearly toward the lock position while the stopper hole 26 abuts against the stopper 26 as the stopper 26 moves toward the lock side based on the biasing force of the spring 28.

  When the lock bar 23 is positioned at the lock position and the magnet 27 of the stopper 26 moves to a position facing the second Hall element 39, the second Hall element 39 detects that the lock bar 23 has reached the lock position. Is done. At this time, the drive of the motor 22 is stopped and the lock bar 23 is stopped at the lock position. Accordingly, as shown in FIGS. 7 and 8, the locking claw 16 is pressed from above by the lock bar 23 and is in a state where it cannot be displaced from the engaged state, that is, a locked state. When the charging on / off switch 62 is turned on in this locked state, a current is supplied from the power supply plug 10 to the inlet portion 20 and charging of the battery 4 is started.

  Here, when the locking claw 16 is in the locked state, for example, it is assumed that a third party or the like performs a forcible pulling operation in order to forcibly remove the power supply plug 10 from the inlet portion 20. At this time, a forceful pulling load accompanying the pulling operation is generated in the locking claw 16, and the locking claw 16 moves upward. However, since the lock bar 23 is positioned above the locking claw 16, even if the locking claw 16 tries to lift upward, this movement is restricted by the lock bar 23, and the locking claw 16 is engaged. The state of being caught by the joint portion 21 is maintained. As a result, even if the power plug 10 is forcibly taken over, the connection of the power plug 10 is maintained, and unauthorized removal of the power plug 10 is prevented.

  By the way, the locking claw 16 of the power supply plug 10 is not securely engaged with the engaging portion 21 of the inlet portion 20 for some reason, and is hooked on the top of the engaging convex portion 21b. It is also assumed that a half-fitted state that does not completely fit into the convex portion 21b is assumed. In this half-fitted state, the linear movement of the lock bar 23 to the lock position is obstructed by the locking claw 16 of the power supply plug 10, and the lock bar 23 cannot be linearly moved to the lock position.

  However, since the lock device 30 of the present embodiment has a structure in which the motor 22 and the lock bar 23 are mechanically separated by the stopper 26, when the motor 22 falls into such a semi-fitted state, the motor 22 The lock bar 23 is maintained in a state where it is stopped by an obstacle even if it takes an action of rotating to the end. Therefore, for example, it is not necessary to take the operation of forcibly moving the lock bar 23 that cannot be moved by an obstacle with the driving force of the motor 22, so that an excessive load is applied to the motor 22, the transmission member 25, the stopper 26 and the like. Therefore, it is possible to prevent the motor 22, the transmission member 25, the stopper 26, and the like from being damaged.

  Further, when the half-fitted state is reached, if the power supply plug 10 is moved by a small amount up and down and left and right in the manner of alignment, the half-fitted state is released, and the locking claw 16 moves relative to the engaging portion 21. It switches to the mating state that has been engaged properly. At this time, due to the biasing force of the spring 28, the lock bar 23 moves by itself to the lock position side and finally is located at the lock position. Therefore, even if the semi-fitted state occurs, the lock bar 23 can be positioned at the locked position, so that the power supply plug 10 is not left in the unlocked state.

  On the other hand, when the charging of the battery 4 is completed, the process moves to the operation of removing the power supply plug 10 from the inlet portion 20 and the user operates the removal switch 76. When the removal switch 76 detects that it has been pushed, it outputs an operation signal to the charging ECU 75. When the operation signal is input from the removal switch 76, the charging ECU 75 sets a removal operation flag in the memory 75a. When the ID verification establishment flag and the removal operation flag are set, the charging ECU 75 outputs a reverse rotation driving signal to the motor 22 and starts the unlocking operation of the locking claw 16.

  At this time, when the motor 22 is driven in reverse rotation, this driving force causes the transmission member 25 to rotate in the opposite direction to that in the locked state, and the stopper 26 moves linearly toward the unlock side. At this time, the lock bar 23 has its own buffer hole 23a pushed to the unlock side by the stopper 26, and moves toward the unlock position against the urging force of the spring 28 as the stopper 26 moves to the unlock side. And go straight ahead.

  When the lock bar 23 is located at the unlock position and the magnet 27 of the stopper 26 moves to a position facing the first hall element 38, the fact that the lock bar 23 has reached the unlock position is indicated by the first hall element 38. Is detected. At this time, the drive of the motor 22 is stopped and the lock bar 23 is stopped at the unlock position. As a result, as shown in FIGS. 5 and 6, the state where the upper portion of the locking claw 16 is pressed by the lock bar 23 is released. As a result, the latching claw 16 can be opened and operated by pushing the operation unit 17, and therefore the latching claw 16 can be opened and the power supply plug 10 can be removed from the inlet portion 20.

  Incidentally, for example, in the locked state shown in FIG. 10, when the lock bar 23 is displaced to the unlock position, it is assumed that the motor 22, the charging ECU 75, etc. cannot drive the lock bar 23 from the lock position due to some abnormality. . In such an abnormality, the locking device 30 is not released regardless of how many times the removal switch 76 is pressed, and the locking claw 16 cannot be removed from the engaging portion 21, so that the power supply plug 10 cannot be pulled out from the inlet portion 20.

  However, the lock device 30 of the present embodiment has a structure in which the motor 22 and the lock bar 23 are mechanically separated by the stopper 26, and the push operation unit 54 that can manually operate the lock bar 23 is manually operated. It is connected to the guide member 51 of the lock bar 23 via the release holding mechanism 53. Therefore, when the locking device 30 is abnormal, the user establishes collation with the electronic key 80 to unlock the door lock, and after getting on, the user pushes the push operation unit 54. As a result, the lock bar 23 moves from the lock position to the unlock position against the urging force of the spring 28, and the lock device 30 changes from the lock state to the unlock state.

  At this time, the stopper 26 does not move and remains in the locked position, but the lower rail protrusion 26d of the stopper 26 moves relatively in the buffer hole 23a of the lock bar 23, so that the lock bar 23 is allowed to move to the unlock position. And as FIG. 11 shows, the lock bar 23 is located in an unlock position, and a locked state changes to cancellation | release. Here, since the movable portion 55 is held at the unlock position by the manual release holding mechanism 53, the lock manual release mechanism 50 takes the manual release holding state, and the lock bar 23 can be maintained in the unlocked state. When the push operation unit 54 is pushed again, the movable unit 55 returns to the original position and the lock manual release mechanism 50 returns to the normal state.

  Therefore, even if the lock device 30 is in a locked state and fails, the lock device 30 can be unlocked by a manual operation, so that the power supply plug 10 can be removed from the inlet portion 20. For this reason, since the engine start is permitted, if the key verification is completed in the vehicle, the hybrid system 3 is started by pressing the start switch, and the vehicle 1 can be carried to a dealer or the like for repair of the lock device 30. It becomes possible.

  In the present embodiment, when the power supply plug 10 is inserted into the inlet portion 20 and the engaging claw 16 is engaged with the engaging convex portion 21b, the lock bar 23 is positioned at the locked position by driving the motor 22, The locking claw 16 can be brought into a locked state where it cannot be removed. For this reason, the third party cannot arbitrarily remove the power plug 10 from the inlet portion 20, and the power plug 10 can be prevented from being stolen.

  Further, when the lock bar 23 cannot be driven from the locked position to the unlocked position due to some abnormality such as the motor 22 or the charging ECU 75, the user manually pushes the push operation unit 54 by the lock manual release mechanism 50. Thus, the lock bar 23 can be moved to the unlock position. Therefore, even if the lock bar 23 cannot be driven from the locked position to the unlocked position due to some abnormality such as the motor 22 or the charging ECU 75, the lock bar 23 can be manually moved, and the locking claw 16 is unlocked. can do.

  Furthermore, since the release state is automatically held by the manual release holding mechanism 53, there is no need to continue the push operation in order to maintain the release state, and the power plug 10 is released from the push operation unit 54 and the inlet plug 20 is removed. Can be removed from. Therefore, no special operation is required to maintain the release state, and convenience can be enhanced.

As described above, according to the embodiment described above, the following effects can be obtained.
(1) Since the locking device 30 is provided in the inlet portion 20, it is possible to prevent the power supply plug 10 connected to the inlet portion 20 from being unintentionally removed from the inlet portion 20 by a third party. Further, the lock bar 23 and the stopper 26 have a mechanically separated structure with a spring 28 interposed therebetween, and a push operation unit 54 that can be manually operated on the lock bar 23 has a manual release holding mechanism. 53 is connected. For this reason, even if the motor 22 or the like becomes abnormal and the lock bar 23 cannot be driven, the user can manually move the lock bar 23 to the unlock position by pushing the push operation unit 54. And can be held in the unlocked position. Further, when the lock device 30 is manually released by the push operation unit 54, the manual release state is held by the manual release holding mechanism 53. Therefore, even if the hand is released from the push operation unit 54, the manual release state is maintained, so that convenience can be improved.

  (2) The lock bar 23 can be changed from the locked state to the unlocked state by the push operation to the push operation unit 54, and the lock bar 23 can be changed to the transition state by the motor 22 by performing the push operation again. For this reason, the user can manually change the lock bar 23 to the unlocked state or the normal transition state by repeating an easy operation called a push operation.

  (3) The stopper 26 is locked in the buffer hole 23a of the lock bar 23, and the motor 22 and the lock bar 23 are mechanically separated by the stopper 26 reciprocating in the buffer hole 23a. For this reason, when the push operation unit 54 is manually operated, only the lock bar 23 is moved to the lock position, so that the locked state can be forcibly released without imposing a large operation load on the user. .

(4) Since the manual release holding mechanism 53 is provided, the operation of the push operation unit 54 can be easily held.
(5) Since the guide member 51 and the link 52 are transmitted only when the loose fitting portion 51a formed on the guide member 51 is moved to the unlock position by the operation of the push operation portion 54, the manual release is not normally performed. Sometimes the lock bar 23 can be left free. Therefore, during normal times, there is no load due to the link 52 and the movable portion 55, so that an increase in load applied to the motor 22 and the like can be suppressed.

  (6) Since the push operation unit 54 of the lock manual release mechanism 50 is provided in the vehicle, even if a third party attempts to manually release the lock device 30 illegally, the third party cannot get into the vehicle. It is unlikely that the lock device 30 is manually released by the three parties. Therefore, it is possible to make it difficult for unauthorized manual release of the lock device 30 to occur.

  (7) Since the lock bar 23 and the motor 22 can be attached to the main body case 31 so as to be housed in order, the lock device 30 can be assembled by a simple operation that is easy to assemble.

(Second Embodiment)
Hereinafter, a second embodiment in which the present invention is embodied in a power receiving connector of a plug-in hybrid vehicle will be described with reference to FIGS. This embodiment is different from the first embodiment in the structure of the locking device 30. Hereinafter, a description will be given focusing on differences from the first embodiment. In addition, the lock manual release mechanism of the connector lock structure of the power receiving connector of this embodiment has substantially the same configuration as the lock manual release mechanism of the connector lock structure of the power receiver connector of the first embodiment.

First, the structure of the locking device 30 of this embodiment will be described.
The lock bar 43 as a regulating member is formed in a rod shape. The lock bar 43 is provided with a lock portion 43a that restricts the displacement of the locking claw 16 and a shaft portion 43b that is connected to the lock portion 43a and is inserted inside the spring 48 as an urging means. The outer diameter of the shaft portion 43b of the lock bar 43 is smaller than the outer diameter of the lock portion 43a. The stopper 46 is formed with a hole 46e as a recess into which the shaft 43b of the lock bar 43 is inserted. That is, the lock bar 43 is assembled to the hole 46e of the stopper 46 so as to be relatively movable.

  The spring 48 is fitted on the outer periphery of the shaft portion 43 b of the lock bar 43, and is positioned between the step portion between the lock portion 43 a and the shaft portion 43 b of the lock bar 43 and the lower rail protrusion 46 d of the stopper 46. . A catch 43 c as a retaining member is attached to the end of the shaft portion 43 b of the lock bar 43 so that the lock bar 43 does not come off from the stopper 46. A catch groove 43d into which the catch 43c is fitted is formed in the attachment portion of the catch 43c of the shaft portion 43b. Thereby, the catch 43c is difficult to come off from the lock bar 43 in the axial direction.

  The lock bar 43 is always urged by the spring 48 toward the side where the lock portion 43 a is separated from the stopper 46, and the catch 43 c is maintained in contact with the stopper 46. When the stopper 46 is displaced from the lock position to the unlock position while the stopper 46 is in contact with the catch 43c, the lock bar 43 can be displaced from the lock position to the unlock position. A lower rail protrusion 46 d that guides the linear reciprocation of the stopper 46 in the axial direction is provided below the stopper 46. The lower rail protrusion 46d is fitted in a stopper lower rail groove 32f formed in the lower part of the inner surface of the main body 32.

  As in the first embodiment, the lock device 30 is provided with a lock manual release mechanism 50 that can manually release the lock bar 43 from the locked state. One end of the link 52 is loosely fitted in a loosely fitting portion 51 a of the guide member 51 formed on the side portion of the lock portion 43 a of the lock bar 43.

Next, the function of the locking device 30 will be described with reference to FIGS.
As shown in FIG. 13, when the motor 22 is driven in the unlocked state where the locking claw 16 is not regulated, the transmission member 25 is rotated by this driving force, and the male screw portion 25 a of the transmission member 25 and the stopper 46. The stopper 46 is converted into a rectilinear movement in the longitudinal direction of the main body case 31 by screwing with the female screw portion 46a. The stopper 46 starts a straight movement toward the motor 22 side of the main body case 31, that is, the lock position side. At this time, the lock bar 43 moves straight toward the lock position while the catch 43c abuts against the stopper 46 as the stopper 46 moves to the lock position side based on the biasing force of the spring 28. Then, as shown in FIG. 14, a locked state in which the movement of the locking claw 16 is restricted is taken.

  On the other hand, when the charging of the battery 4 is completed, the operation shifts to the operation of removing the power supply plug 10 from the inlet portion 20 this time, and when the motor 22 is driven in reverse rotation, this driving force causes the transmission member 25 to rotate in the reverse direction. Then, the stopper 46 moves so as to move straight toward the unlock position. At this time, the lock bar 43 is pushed to the unlock position side when the lower rail protrusion 46d of the stopper 46 comes into contact with the catch 43c, and moves straight toward the unlock position as the stopper 46 moves to the unlock position side. Moving.

  As shown in FIG. 13, when the lock bar 43 is located at the unlock position, the lock bar 43 is stopped at the unlock position. As a result, the state in which the upper portion of the locking claw 16 is pressed by the lock bar 43 is released.

  Incidentally, for example, in the locked state shown in FIG. 15, when the lock bar 43 is displaced to the unlock position, it is assumed that the motor 22, the charging ECU 75, etc. cannot drive the lock bar 43 from the lock position due to some abnormality. . When such an abnormality occurs, the lock device 30 of the present embodiment can move the lock bar 43 to the unlock position side when the user manually pushes the push operation unit 54 as in the first embodiment. it can. At this time, the stopper 46 does not move and remains in the locked position, but the shaft portion 43b of the lock bar 43 relatively moves in the hole 46e of the stopper 46. Can move.

  As shown in FIG. 16, when the user manually pushes the push operation unit 54, the lock bar 43 can be positioned at the unlock position. Here, since the movable portion 55 is held at the unlock position by the manual release holding mechanism 53, the lock bar 43 can be maintained in the unlocked state.

  Incidentally, in the conversion mechanism composed of the male screw portion 25a of the transmission member 25 and the female screw portion 46a of the stopper 46, when the transmission member 25 continues to rotate and the stopper 46 is driven beyond the lock position or the unlock position. Further, an idling mechanism for separating the driving force from the transmission member 25 to the stopper 46 is provided. That is, the driving force from the transmission member 25 to the stopper 46 is such that the male screw portion 25a of the transmission member 25 is formed with a screw only in a range corresponding to between the lock position and the unlock position. It is transmitted only at the portion where is formed, and is not transmitted except the male screw portion 25a, and the stopper 46 is not displaced even when the transmitting member 25 rotates.

  On the surface facing the stopper 46 of the second lid portion 34, when the stopper 46 exceeds the unlock position and the idling mechanism functions, the stopper 46 is urged toward the lock position to return to the unlock position. A spring 49 is fixed. When the stopper 46 exceeds the unlock position, the return spring 49 comes into contact with the stopper 46 and is compressed to urge the stopper 46 to the unlock position. Further, when the stopper 46 exceeds the lock position and the idling mechanism functions, the stopper 46 is urged toward the unlock position by the spring 48 fitted to the lock bar 43 to return to the lock position. When the stopper 46 exceeds the lock position, the spring 48 is compressed by moving the stopper 46 toward the lock portion 43a and urges the spring 48 to the lock position.

  When the lock bar 43 cannot be driven from the lock position to the unlock position due to some abnormality such as the motor 22 or the charge ECU 75, the user manually pushes the push operation unit 54 to unlock the lock bar 43. It can be moved to the locked position. Therefore, even if the lock bar 43 cannot be driven from the locked position to the unlocked position due to some abnormality such as the motor 22 or the charging ECU 75, the lock bar 43 can be manually moved.

As described above, according to the embodiment described above, the following functions and effects can be achieved in addition to the functions and effects of (1), (2) and (4) to (7) of the first embodiment.
(8) The lock bar 43 is fitted and inserted into the hole 46e formed in the stopper 46, and the lock bar 43 moves in the hole 46e. For this reason, the positional relationship between the lock bar 43 and the stopper 46 is fixed and the moving direction is restricted, and the motor 22 and the lock bar 43 are mechanically separated. Therefore, the lock bar 43 is biased to the lock position by the spring 48 so as to surely reach the lock position. However, only the lock bar 43 can be moved to the unlock position without any problem during manual operation. it can.

In addition, the said embodiment can be implemented with the following forms which changed this suitably.
In the above embodiment, the lock bars 23 and 43 are manually moved to the unlock position by a push operation. However, the lock bars 23 and 43 may be manually moved to an unlock position by another operation. Good.
