Abstract

PROBLEM TO BE SOLVED: To provide a power feeding plug locking device capable of suppressing early deterioration of components and securing convenience during operation.SOLUTION: When a power feeding plug is connected to an inlet 24, a lock bar 39 linearly moves the depth while being pushed by a lock arm 27. When the lock arm 27 drops in a protruding part 32 during the operation process, the lock bar 39 jumps out by an energizing force of an energizing member 42 and the lock bar 39 and a lever 43 are located above the lock arm 27, then the power feeding plug locking device is put into a locked state. When the lock bar 39 is pulled to the depth and separated from the lever 43 while locking the power feeding plug locking device 33, the lever 43 is rotated downward, and a position of the lock bar 39 is held by a side surface 43a. For that reason, the rocking operation of the lock arm 27 is allowed and the power feeding plug is enabled to be pulled out from the inlet 24.

Description

  The present invention relates to a power plug locking device that locks a power plug connected to an article such as a vehicle, for example, to prevent unauthorized removal of the power plug.

  In recent years, with increasing awareness of environmental issues, for example, hybrid vehicles and electric vehicles have been widely used as vehicles with low carbon dioxide emissions. These vehicles are driven by the driving force of the motor by rotating the motor with the electric power of the battery. Therefore, when the battery runs for a long distance and the remaining amount of the battery decreases, the battery must be charged each time (see Patent Document 1).

  By the way, since battery charging is accompanied by the electrolytic reaction of a compound or ion with the battery cell which is a component of a battery, there exists the present condition that charging time takes comparatively long. Therefore, if the user leaves the vehicle while the battery is being charged, there is a possibility that the power will be stolen by a third party changing the power plug. For this reason, in a vehicle that can be charged by a battery, it has been studied to mount a lock device so that the power plug is not pulled out from the vehicle when the power plug is inserted into the vehicle.

  By the way, in this kind of power supply plug lock device, for example, a technique has been devised in which a lock / unlock operation is interlocked with a door lock / door unlock of a vehicle door (see Patent Document 2). This technique causes the power plug lock device to perform a locking operation when the vehicle door is locked, and causes the power plug lock device to perform an unlock operation when the vehicle door is unlocked. By doing so, since the operation of the power supply plug lock device is completed when the vehicle door is locked and unlocked, no separate operation is required when operating the power supply plug lock device.

  However, in this case, the power plug lock device operates every time the vehicle door is locked and unlocked regardless of whether or not the power plug is connected to the vehicle. There was a concern of causing early deterioration. If the lock / unlock of the power plug lock device is interlocked with the lock / unlock of the vehicle door, the power supply of the power plug lock device is required each time the vehicle door is locked / unlocked. It will also lead to problems that are consumed.

  Therefore, in order to solve such a problem, a structure in which the power supply plug lock device is switched to a locked state by manual operation such as button operation is also assumed. In this way, the locking device can be switched to the locked state according to the user's will, so that the power supply plug locking device can be switched to the locked state only when it is really necessary, preventing early deterioration of parts and the vehicle. The power saving of the power supply can be satisfied. However, since this time a manual operation is imposed on the user, using this technique leads to a problem that impairs convenience.

  An object of the present invention is to provide a power supply plug lock device that can suppress early deterioration of components and can ensure convenience during operation.

  In order to solve the above problem, in the present invention, when a power plug is connected to the inlet, a lock arm provided as a retaining claw on the power plug is fixed to the protrusion of the inlet by a lock mechanism. Thus, in the power plug locking device that prevents unauthorized removal of the power plug, the lock mechanism biases the lock member linearly movable in the insertion / removal direction of the power plug and the lock member toward the power plug. An urging member; and a lever member that approaches and separates from the power plug inserted into the inlet, and when the power plug is inserted into the inlet, the lock member in a state in which the lever member is placed is The lock arm is pushed against the urging force of the urging member, and the lock arm is pushed in the insertion process. The locking member pops out by the urging force of the urging member, the locking member and the lever member lock the locking arm, and the locking member is pulled into the back. The gist of the invention is that when the lever member moves away from the lever member, the lever member moves toward the lock arm side to hold the position of the lock member on the side surface, thereby allowing the lock arm to move.

  According to the configuration of the present invention, when the power supply plug is connected to the inlet, the power supply plug lock device performs a locking operation in conjunction with the connection operation. Therefore, only when the power supply plug is connected to the inlet, the power supply plug lock device is connected to the power supply plug lock device. It is possible to take a locking action. For this reason, it is not necessary to cause the power supply plug lock device to perform a useless locking operation, so that it is possible to suppress early deterioration of components. When the power plug is connected to the inlet, the power plug lock device is switched to the locked state at that time. Therefore, when switching to the locked state, there is no need to operate a button or the like separately, and convenience can be ensured.

  Further, when the power plug locking device is in the locked state, when the lock member is pulled back and separated from the lever member, the lever member moves to the lock arm side, and the position of the lock member is held on the side surface of the lever member; Become. For this reason, since only the movable lever member is positioned above the lock arm, the operation of the lock arm is allowed, and as a result, the power supply plug can be pulled out from the inlet. Therefore, the power supply plug lock device in the locked state can be switched to the unlocked state without any problem.

  The gist of the present invention is that the lock mechanism includes drive means for moving the lock mechanism to an unlocked state by moving the lock member to the back by moving electrically. According to this configuration, since the lock member is retracted by the driving means during the unlocking operation, the lock member can be automatically retracted. Therefore, since it is not necessary to impose the lock member on the user, it is possible to ensure convenience during the unlocking operation. In this case, electric power is required to drive the driving means. However, since energization is temporary, power saving can be ensured.

  In the present invention, the lever member is rotatable about the insertion / removal direction of the power plug, and when the lock member is separated during the unlocking operation, the lever member is moved toward the lock arm by the urging force of the urging member. The gist of the invention is that it is brought into contact with the lock arm and is in an unlocked state in which the lock member is held in position by the side surface. According to this structure, it becomes possible to make the structure of the power supply plug lock device a simple structure in which the lever member that rotates and the lock member that moves linearly are combined.

  The gist of the present invention is that the lock mechanism includes manual release means capable of switching the lock mechanism in the locked state to the unlocked state by manual operation. According to this configuration, even if the locked state of the power plug locking device cannot be released to the unlocked state for some reason, the power plug locking device can be switched to the unlocked state by the manual release means. Therefore, the power supply plug cannot be removed from the inlet, and the vehicle cannot run.

  In the present invention, when the vehicle door takes an unlocking action, the locking mechanism drives the driving means to perform its own unlocking action in conjunction with the unlocking action of the vehicle door. The gist. According to this configuration, the unlocking operation of the power plug locking device is linked to the unlocking operation of the vehicle door. For this reason, when the power feeding plug lock device is switched to the unlocked state, a special operation is not required separately, and convenience can be improved.

  According to the present invention, early deterioration of parts can be suppressed, and convenience during operation can be ensured.

Hereinafter, an embodiment of a power supply plug lock device embodying the present invention will be described with reference to FIGS.
As shown in FIG. 1, a hybrid vehicle (hereinafter simply referred to as a vehicle 1) is provided with a hybrid system 4 that generates power for turning wheels by an engine 2 or a motor 3. The hybrid system 4 is provided with a battery 5 as a power source for the motor 3. The vehicle 1 travels in various modes such as a mode in which power is generated by the power of the engine 2 and travels by the motor 3, a mode in which both the engine 2 and the motor 3 are traveled as power, and a mode in which the motor 3 travels alone.

  The vehicle 1 is equipped with an electronic key system 7 for operating the vehicle 1 by performing ID verification wirelessly with the electronic key 6. The electronic key system 7 of this example is a wireless key system that performs ID collation triggered by communication from the electronic key 6.

  In this case, the vehicle 1 is provided with a key verification device 8 that performs ID verification with the electronic key 6 and a door lock device 9 that performs door lock locking / unlocking of the vehicle door, which are connected by an in-vehicle bus 10. Has been. The key verification device 8 is provided with a verification ECU (Electronic Control Unit) 11 that performs overall control of the operation of the key verification device 8. The ID code of the electronic key 6 is registered in the memory of the verification ECU 11. The verification ECU 11 is connected to a vehicle receiver 12 that can receive radio waves in the UHF (Ultra High Frequency) band. The door lock device 9 is provided with a door lock ECU 13 that performs overall control of door lock locking and unlocking operations. A door lock motor 14 is connected to the door lock ECU 13 as a drive source for switching between locking and unlocking the door lock.

  The electronic key 6 is provided with a key control unit 15 that manages communication operations on the key side. The ID code of the electronic key 6 is registered in the memory of the key control unit 15. The electronic key 6 is provided with a plurality of operation buttons 16 that are operated when the vehicle 1 is remotely operated. The operation buttons 16 include a lock button that is operated when the door lock is locked, an unlock button that is operated when the door lock is unlocked, and the like.

  When the operation button 16 is operated, a wireless signal Sid is transmitted from the electronic key 6 by radio waves in the UHF band. The wireless signal Sid includes an ID code and a function code corresponding to the operated operation button 16. When the verification signal is received by the vehicle receiver 12, the verification ECU 11 executes ID verification using the ID code in the wireless signal Sid. When the verification ECU 11 confirms the establishment of the ID verification, the verification ECU 11 causes the vehicle 1 to execute an operation according to the function code in the wireless signal Sid.

  For example, when the door lock request signal is received as the wireless signal Sid from the electronic key 6 when the door lock is locked, the door lock motor 14 is rotated forward, for example, on the condition that the ID verification is established, and the door side locking member (illustration is shown). Is omitted). Therefore, the door lock is locked. On the other hand, when the door unlock request signal is received as the wireless signal Sid from the electronic key 6 in the door lock unlocked state, the door lock motor 14 is reversed, for example, on condition that the ID verification is established, and the locking member is removed from the vehicle body. The Therefore, the door lock is unlocked.

  The vehicle 1 is provided with a charging system 17 that charges the battery 5 with an external power source. The charging system 17 connects a power supply plug 19 provided at the tip of a charging cable 18a of the charging facility 18 to the vehicle 1 by using, for example, a charging stand installed in a corner of the city or a commercial commercial power source as a charging facility 18. The battery 5 is charged.

  As shown in FIGS. 1 and 2, a power receiving connector 21 is provided on the left front side wall of the vehicle body 20 as a connection location of the power supply plug 19. In the power receiving connector 21, the storage chamber 23 is opened and closed by a laterally open lid 22. The power receiving connector 21 is provided with an inlet 24 having electrical connection terminals (power terminals, control terminals). The inlet 24 is provided with a plug connection detection sensor 25 that detects that the power supply plug 19 is completely inserted. In addition, a rubber lid 26 that opens and closes an electrical connection terminal of the inlet 24 is attached to the inlet 24 so as to be able to open sideways.

  As shown in FIGS. 2 and 3, the power supply plug 19 is provided on the power supply side of the charging system 17 and provided with an electrical connection terminal connected to the inlet 24. A lock arm 27 is swingably attached to the plug body 19a of the power supply plug 19 as a retaining member at the time of connection. The lock arm 27 swings in the vertical direction with the center in the longitudinal direction as a rotation shaft 28. The lock arm 27 has a claw portion 29 at the tip and a base operation portion 30 exposed to the outside of the plug body 19a. A biasing member 31 that constantly biases the lock arm 27 toward the closing side is provided at a position near the operation unit 30 in the lock arm 27.

  When connecting the power supply plug 19 to the power reception connector 21, the power supply plug 19 is inserted straight into the power reception connector 21 in the insertion direction (the −Y axis direction in FIG. 3). At this time, when the claw portion 29 comes into contact with the protrusion 32 of the inlet 24, the lock arm 27 is guided by the inclined surface 32 a and goes up the protrusion 32. When the power supply plug 19 is completely inserted into the inlet 24, the lock arm 27 swings to the closed side by the urging force of the urging member 31. For this reason, the nail | claw part 29 is hooked on the protrusion 32, and the electric power supply plug 19 is prevented from falling out to the inlet 24.

  When the hybrid system 4 detects that the power plug 19 is completely inserted into the inlet 24 by the plug connection detection sensor 25, the hybrid system 4 outputs a charge start request to the power plug 19. When the power supply plug 19 receives a charge start request from the hybrid system 4, the power supply plug 19 supplies a current to the power receiving connector 21 to charge the battery 5. When the hybrid system 4 confirms that the battery 5 is fully charged, it outputs a charge termination request to the power supply plug 19. When the power plug 19 receives a charge termination request from the hybrid system 4, the power plug 19 stops the current supply to the power receiving connector 21 and terminates the charging.

  When removing the power supply plug 19 from the inlet 24, the operating portion 30 is pushed to swing the lock arm 27 to the open side and away from the protrusion 32. In this state, the power supply plug 19 is removed from the vehicle 1 by pulling it straight out from the inlet 24.

  As shown in FIGS. 4 to 6, the power receiving connector 21 is provided with a power plug locking device 33 that prevents unauthorized removal of the power plug 19 connected to the inlet 24. When the power supply plug 19 is inserted into the inlet 24, the power supply plug lock device 33 of this example mechanically switches itself to the locked state in conjunction with the insertion operation. Further, when the power supply plug lock device 33 is switched from the locked state to the unlocked state, it is electrically executed by an actuator such as a motor.

  The power plug lock device 33 is provided with a case 34 having a substantially rectangular box shape. The case 34 includes a lock body 35 that houses a group of components of the power plug lock device 33 and a lid 36 that closes the opening of the lock body 35. The lock body 35 has a shape with an open front side. The lock body 35 and the lid 36 are assembled together by a plurality of locking pins 37, for example. For example, a screw is used as the locking pin 37. The case 34 is in an attached state in which the lock body 35 is fixed to the inlet 24 by a plurality of locking members (not shown). On the front surface of the lid 36, a recess 36 a is formed through which the lock arm 27 passes when the power supply plug 19 is connected to / removed from the inlet 24.

  Inside the case 34, a lock mechanism 38 is provided as a mechanism part of the power supply plug lock device 33. In this case, a lock bar 39 having a substantially rectangular parallelepiped shape is provided inside the case 34 so as to be linearly reciprocable in the apparatus depth direction (Y-axis direction in FIG. 4). The lock bar 39 is integrally provided with a main body portion 40 of the lock bar 39 and a position restricting portion 41 that is narrower in the apparatus height direction Z than the main body portion 40. The position restricting portion 41 is a member that restricts the position of the lock bar 39 from above, and is formed by a part protruding from the main body portion 40. A biasing member 42 that constantly biases the lock bar 39 in the protruding direction is interposed between the case 34 and the lock bar 39. For this reason, the lock bar 39 is slidable in the protruding direction (in the direction of arrow K1 in FIG. 4) by the urging member 42 of the urging member 42, and is retracted against the urging force of the urging member 42 (see FIG. 4 in the direction of arrow S1). As the urging member 42, for example, a coil spring is used. The lock bar 39 corresponds to the lock member, and the apparatus depth direction Y corresponds to the insertion / removal direction.

  In addition, a lever 43 capable of regulating the swing of the lock arm 27 in cooperation with the lock bar 39 is attached to the inside of the case 34 by a pin member 44 extending in the apparatus depth direction Y. The lever 43 is rotatable about the axis La of the pin member 44 and is rotated in a direction intersecting with the linear movement direction of the lock bar 39 (Y-axis direction in FIG. 4). The lever 43 is attached with a biasing member 45 that constantly biases the lever 43 in the tilting direction. For this reason, the lever 43 is rotated in the tilting direction (the direction of the arrow K2 in FIG. 4) by the urging force of the urging member 45, and is lifted against the urging force of the urging member 45 (the direction of the arrow S2 in FIG. 4). ). As the urging member 45, for example, a torsion spring is used. The lever 43 corresponds to a lever member.

  When the power plug 19 is connected to the inlet 24, when the lock bar 39 moves linearly in the protruding direction and the lock bar 39 and the lever 43 overlap with each other and get on the lock arm 27, the power plug lock device 33 is The lock arm 27 is in a locked state in which the swing operation is restricted. In addition, when the lock bar 39 is pulled into the retracted position from this locked state and only the lever 43 is on the lock arm 27, the power plug lock device 33 is in an unlocked state in which the swing operation of the lock arm 27 is allowed. Become.

  The power plug lock device 33 is provided with an actuator 46 that can retract the lock bar 39 to the back. The actuator 46 brings the lock mechanism 38 into the unlocked state by pulling the lock bar 39 in the protruding position into the retracted position. For example, a suction solenoid is used as the actuator 46 and is connected to the power source + B of the vehicle 1 via a harness (not shown). Normally, the actuator 46 is not energized, and when the lock bar 39 is positioned at the protruding position and is energized, the lock bar 39 is pulled into the back retracted position during the energization period. The actuator 46 corresponds to a driving unit.

  As shown in FIG. 7, the door lock ECU 13 is connected to an unlock side relay 47 that is turned on when the door is unlocked and a lock relay 48 that is turned on when the door is locked. A door lock motor 14 is connected to the door. When the vehicle 1 receives a door lock request signal from the electronic key 6, the door lock ECU 13 turns off the unlock side relay 47 and turns on the lock side relay 48 to rotate the door lock motor 14 in one direction. On the other hand, when the vehicle 1 receives a door unlock request signal from the electronic key 6, the door lock ECU 13 turns on the unlock side relay 47 and turns on the lock side relay 48 to rotate the door lock motor 14 in the other direction. Let

  The actuator 46 is connected in parallel to the door lock motor 14 by extending a harness from the motor circuit of the door lock motor 14. On the harness of the actuator 46, a plug lock detector 49 that detects that the power plug lock device 33 is in a locked state is connected. The plug lock detection unit 49 is composed of, for example, a micro switch, and is mechanically turned on when the lock mechanism 38 is locked by the lock bar 39 and the lever 43. A reverse current preventing diode 50 is connected between the actuator 46 and the plug lock detector 49.

  When the door lock is locked, a current (current Ia in FIG. 7) flows from the lock-side relay 48 to the unlock-side relay 47 in the door lock motor 14. For this reason, since the voltage of the unlock side terminal 14a of the door lock motor 14 becomes a low potential, no current flows through the actuator 46 regardless of whether the plug lock detection unit 49 is on or off, and the actuator 46 Does not work. Note that the unlock side terminal 14a is a terminal on the side of the positive terminal and the negative terminal of the door lock motor 14 that is at a high potential when the door lock motor 14 performs an unlock operation.

  On the other hand, when the door lock is unlocked, a current (current Ib in FIG. 7) flows from the unlock side relay 47 to the lock side relay 48 in the door lock motor 14. For this reason, since the voltage of the unlock side terminal 14a becomes a high potential, if the plug lock detection unit 49 is on, a current flows through the actuator 46, and the power supply plug lock device 33 performs the unlock operation. The actuator (suction solenoid) 46 performs the pull-in operation of the lock bar 39 only when a current flows through the actuator (suction solenoid) 46 itself.

Next, operation | movement of the electric power feeding plug lock apparatus 33 of this example is demonstrated using FIGS. 8-13.
First, FIG. 8 shows the power supply plug lock device 33 in the unlocked state. At this time, since the actuator 46 is in a non-energized state as shown in the figure, the lock bar 39 takes a protruding position by the urging force of the urging member 42 to support the lever 43. For this reason, the lever 43 does not take a state in which the tip falls down, so that the power supply plug 19 can be freely connected to the inlet 24. At this time, the lock bar 39 is prevented from coming off when the stepped portion 40 a of the main body 40 contacts the side surface 43 a of the lever 43.

  As shown in FIG. 9, when the power supply plug 19 is inserted into the inlet 24, the lock arm 27 pushes the lock bar 39 inward in the insertion process. At this time, the lock bar 39 is linearly moved in the retracting direction (arrow S1 direction in FIG. 9) against the urging force of the urging member 42 by being pushed by the lock arm 27. At this time, the lock bar 39 moves to the back with the lever 43 on top.

  Then, as shown in FIG. 10, when the lock arm 27 gets over the protrusion 32, the lock arm 27 falls down by the urging force of the urging member 31, and the claw portion 29 is locked to the protrusion 32. At this time, the lock arm 27 moves downward with respect to the lock bar 39, so that the state of pressing the lock bar 39 from the side is stopped. For this reason, the lock bar 39 linearly moves in the protruding direction (the direction of the arrow K1 in FIG. 10) by the urging force of the urging member 42 and enters between the lock arm 27 and the lever 43. Therefore, both the lock bar 39 and the lever 43 are positioned above the lock arm 27. At this time, the lock bar 39 is positioned by a stepped portion 29 a formed on the upper surface of the claw portion 29.

  As a result, the position of the lock arm 27 is restricted by the lock bar 39 and the lever 43, and the lock arm 27 cannot swing to the open side. That is, the power supply plug lock device 33 is in a locked state in which the power supply plug 19 is fixed to the inlet 24. When the lock bar 39 is in the locked position, the plug lock detection unit 49 is mechanically turned on.

  Subsequently, when the unlocking operation of the door lock is executed while the power feeding plug locking device 33 is in the locked state, the power feeding plug locking device 33 is unlocked in conjunction with the door unlocking operation. At this time, as shown in FIG. 11, since the unlock current flows through the door lock motor 14, the voltage of the unlock side terminal 14a takes a high potential and the plug lock detector 49 is turned on. Part of Ib also flows to the actuator 46, and the actuator 46 operates.

  As shown in FIG. 12, the actuator 46 moves the lock bar 39 linearly in the retracting direction (in the direction of arrow S1 in the figure) against the biasing force of the biasing member 42 during energization, and is positioned at the retracted position. Let The lock bar 39 is completely separated from the lever 43 when it is in the retracted position. The energization time of the actuator 46 is only a few seconds during which the door lock motor 14 is energized.

  When the lock bar 39 is located at the retracted position, the lever 43 is not supported by the lock bar 39, so that the lever 43 is rotated in the tilting direction (in the direction of arrow K2 in FIG. 12) by the urging force of the urging member 45 and the tip is lowered. Falls to the side. For this reason, after the energization of the actuator 46 is stopped, the lock bar 39 tries to pop out in the protruding direction by the urging force of the urging member 42, but the position is restricted by the side surface 43 a of the lever 43 and the position is maintained at the substantially retracted position. Is done. Therefore, only the lever 43 that is allowed to rotate is positioned above the lock arm 27. That is, the power plug lock device 33 is unlocked.

  As shown in FIG. 13, when the power plug 19 is pulled out from the inlet 24, the operating portion 30 of the lock arm 27 of the power plug 19 is pushed, and the lock arm 27 is swung to the open side. At this time, since only the lever 43 that can be rotated exists above the claw portion 29 of the lock arm 27, the lock arm 27 can be lifted without any problem. That is, the lever 43 is rotated in the lifting direction (the direction of arrow S2 in FIG. 13) by the opening operation of the lock arm 27, and the power supply plug 19 can be pulled out.

  Then, as shown in FIG. 13, when the lever 43 is positioned higher than the position restricting portion 41, the lock bar 39 is released from the position restriction by the lever 43, and the protruding direction (in FIG. It moves linearly in the direction of the arrow K1 and enters the lower side of the lever 43. Subsequently, when the power supply plug 19 is pulled out, the lock bar 39 linearly moves in the protruding direction along with the operation, and finally the lock bar 39 is positioned at the protruding position. Therefore, after the power plug 19 is pulled out from the inlet 24, the power plug lock device 33 returns to the original state shown in FIG.

  As described above, in this example, when the power supply plug 19 is connected to the inlet 24, the lock bar 39 moves linearly while being pushed by the lock arm 27 in conjunction with the connection operation. When the lock arm 27 falls into the protrusion 32 in the operation process, the lock bar 39 pops out by the urging force of the urging member 42, and the lock bar 39 and the lever 43 are positioned above the lock arm 27 and locked. It becomes. That is, the power supply plug locking device 33 performs a locking operation in conjunction with the connection operation of the power supply plug 19.

  For this reason, only when the power supply plug 19 is connected to the inlet 24, the power supply plug lock device 33 can be locked. Therefore, the power supply plug lock device 33 can be prevented from performing a useless lock operation. It becomes possible to suppress early deterioration of parts. In addition, since the power supply plug lock device 33 has a structure in which the power supply plug 19 is mechanically locked in conjunction with the connection operation of the power supply plug 19, there is no need to operate a button or the like for the lock operation. It becomes possible. Furthermore, since no electric power is required for the locking operation, it is possible to save power of the vehicle 1.

  Further, when the power plug locking device 33 is in the locked state, when the lock bar 39 is pulled back by the actuator 46 and separated from the lever 43, the lever 43 rotates to the lock arm 27 side, and the lock bar 39 is moved to the lever 43. It will be in the state hold | maintained by the side surface 43a. For this reason, since only the lever 43 is positioned above the lock arm 27, the rocking operation of the lock arm 27 is allowed, and the power supply plug 19 can be pulled out from the inlet 24. Therefore, the power supply plug lock device 33 in the locked state can be switched to the unlocked state without any problem.

  In the case of this example, the pulling of the lock bar 39 during the unlocking operation is electrically executed by the actuator (suction solenoid) 46. By the way, the pull-in of the lock bar 39 need only be temporarily performed until the lever 43 rotates in the lifting direction and holds the position of the lock bar 39 on the side surface 43a. Therefore, even if the actuator 46 is energized when the lock bar 39 is retracted, the energization time is short, and thus the power saving of the vehicle 1 can be achieved. Further, since the unlocking operation of the power supply plug locking device 33 is interlocked with the door unlocking of the vehicle door, no special operation is separately required for the unlocking operation.

  An IC is provided in the power plug lock device 33, and when this IC confirms that the power plug lock device 33 is locked and the vehicle door is unlocked, the actuator 46 is unlocked. You may make it send an electric current.

The actuator (driving means) 46 is not limited to a solenoid, and for example, a motor or the like may be used.
-You may stop charge of the battery 5 by turning off the switch in a vehicle.

The unlocking operation of the power supply plug lock device 33 is not limited to interlocking with the door lock, and may be manually operated, for example.
The electronic key system 7 is not limited to a wireless key system. For example, it is good also as a short-distance wireless authentication system which uses near field communication, such as NFC (Near Field Communication), for the key operation free system which performs ID collation with communication from the vehicle 1 as a trigger.

-The wireless key system may be a power slide door opening / closing system.
A system in which the door lock is alternately locked and released every time one operation button 16 is operated may be used.

A waterproof mechanism that ensures the airtightness (waterproofness) of the case 34 may be provided. An example of the waterproof mechanism is a seal member provided between the lock body 35 and the lid 36.
The lock bar 39 is not limited to a structure that is positioned directly above the lock arm 27 and restricts the swing of the lock arm 27. For example, the lock bar 39 restricts the swing operation of the lock arm 27 through a predetermined member. Good.

The lock mechanism 38 may adopt any structure as long as it satisfies the technical idea of this example.
The lever member is not limited to a rotating member that rotates around the axis La, and may be a linear moving member that is slidable in the apparatus height direction Z, for example.
