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 electric power plug lock device, the thing of the structure switched to a locked state by manual operation, for example is 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, and early deterioration of the parts can be prevented. Can do. However, in this case, there is a concern that the structure of the device may be complicated because an operation unit that is operated when the power supply plug lock device is switched to the locked state is required.

  An object of the present invention is to provide a power supply plug lock device capable of simplifying the device structure even if the device is configured to be switched to a locked state by manual operation.

  In order to solve the above problems, in the present invention, when a power supply plug is connected to an inlet, a power supply plug that prevents unauthorized removal of the power supply plug by locking a lock member on the inlet side to the power supply plug. In the plug lock device, a knob portion that is operated when operating the lock member is integrally formed with the lock member, and the lock member is locked by manual operation of the knob portion, and the lock member in the locked state is The gist of the invention is that a lock mechanism that holds the lock state of the lock member by being held by the position holding means is provided.

  According to the configuration of the present invention, when the user wants to lock the power plug to the inlet, since the power plug lock device is switched to the locked state by manually operating the knob portion formed integrally with the lock member. Only the feeding plug lock device can be locked. Accordingly, it is not necessary to cause the power supply plug lock device to perform a useless locking operation, and thus it is possible to suppress early deterioration of the parts of the power supply plug lock device. Further, since the knob portion is integrally formed with the lock member, it is not necessary to prepare the knob portion and the lock member separately. For this reason, since the number of parts is reduced, the structure of the power supply plug lock device can be simplified.

  The gist of the present invention is that the lock member is a rotating member, and the knob portion is a rotary operation type. According to this structure, it becomes possible to make the structure of the power supply plug lock device a simple structure in which the lock member is turned by operating the knob portion.

  The gist of the present invention is that a waterproof means for suppressing the intrusion of fluid into the case of the lock mechanism is provided. According to this configuration, the waterproofness of the case is ensured by the waterproof means. Therefore, if the electrical component is accommodated in the case, water or the like hardly adheres to the electrical component. For this reason, it becomes possible to make it hard to produce the failure of the electrical equipment caused by water adhesion.

  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.

  The gist of the present invention is that the lock member is attached to a body portion fixed to the inlet side of the case of the lock mechanism. According to this configuration, when the power plug locking device is in the locked state, even if a third party applies an external force in the unlocking direction to the locking member in an attempt to illegally release the locked state, the force is received by the body portion. It becomes possible. By the way, since the body portion is fixed to the inlet side, it is in a state of being firmly fixed to the vehicle body with a wide contact area, for example. For this reason, even if an improper external force in the unlocking direction is applied to the lock member, it is possible to receive this force at a place that can withstand the external force, and the lock mechanism is destroyed by the external force applied to the lock bar. Is less likely to occur. Therefore, it is possible to make it difficult for unauthorized unlocking to occur.

  In the present invention, the locking mechanism includes a driving unit serving as a driving source when the unlocking operation is performed, and the locking mechanism drives the driving unit when the vehicle door performs the unlocking operation. The gist is to execute its own unlocking operation in conjunction with the unlocking operation of the door. 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.

  In the present invention, the position holding means is a lever that operates integrally with the lock member, and when the lever is in the unlock position, the position holding means is supported by the wall of the lever to be unlocked, and the lever is the lock member. When it moves in the locking direction, the support by the wall is released and moves in the locking direction, and by restricting the operation of the lever, a lock link that holds the lever in a locked state, and the lock link is attached in the locking direction. A biasing member for biasing, and a driving means for switching the lock member to an unlocked state by operating the lock link in the locked position in the unlocking direction against the biasing force of the biasing member. This is the gist. According to this configuration, the structure of the position holding unit can be a simple configuration.

  In the present invention, the lock mechanism receives the external force in the unlocking direction applied to the lock member from the outside by the support surface by bringing the lock link in the locked state into contact with the support surface on the case side. Thus, the gist is provided with an unauthorized release prevention mechanism that suppresses the unauthorized release of the locked state by suppressing the rotation of the lock member in the unlocking direction. According to this configuration, when the power plug locking device is in the locked state, even if a third party applies an external force in the unlocking direction to the locking member in an attempt to unlock the locked state illegally, this force is prevented from being illegally released. It becomes possible to receive at. For this reason, even if an improper external force in the unlocking direction is applied to the lock member, this force can be received by the improper release prevention mechanism, so that it is possible to prevent unauthorized unlocking.

  According to the present invention, the structure of the apparatus can be simplified even if the structure is switched to the locked state by manual operation.

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 is unlocked and the door lock request signal is received as the wireless signal Sid from the electronic key 6, the door lock motor 14 is rotated forward, for example, on condition that the ID verification is established, and the door side locking member ( (Not shown) is locked to the vehicle body. Therefore, the door lock is locked. On the other hand, when the door unlock request signal is received from the electronic key 6 as the wireless signal Sid when the door lock is unlocked, the door lock motor 14 is reversed, for example, on condition that ID verification is established, and the locking member is removed from the vehicle body. Is done. 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. The power supply plug lock device 33 of this example is switched from the unlocked state to the locked state by a manual operation, and the locked state is held by a mechanical structure. In addition, the power supply plug lock device 33 in the locked state is switched to the unlocked state in conjunction with the unlocking operation of the door lock, for example.

A D-shaped groove (not shown) is formed on the back surface of the lever 47, and the lock bar 41 and the lever 47 are assembled together by engaging the engaging portion 42a of the shaft portion 42 in this groove. . When the lock bar 41 is rotated to the back side, the lever 47 rotates in the locking direction (the direction of the arrow K1 in FIG. 4) together with the lock bar 41, and when the lock bar 41 rotates to the near side, the lever 47 is It rotates together with the lock bar 41 in the unlocking direction (the direction of arrow S1 in FIG. 4). The lever 47 constitutes position holding means.

  A biasing member 48 that constantly biases the lever 47 in the unlocking direction is interposed between the case 34 and the lever 47. As the urging member 48, for example, a torsion spring is used. A columnar stopper 47a is provided at the upper portion of the lever 47 as a mounting destination of the urging member 48, and a substantially arc-shaped standing piece 47b extending in the apparatus height direction Z protrudes from the side of the stopper 47a. It is installed. The biasing member 48 has one end locked to the case 34 and the other end locked to the standing piece 47b.

  A lock link 49 that holds the lock bar 41 in the locked position in cooperation with the lever 47 is rotatably mounted inside the case 34 by a pin member 50 that extends in the apparatus depth direction (Y-axis direction in FIG. 4). ing. The lock link 49 is rotatable about the axis Lb of the pin member 50 and is rotated in a direction intersecting the rotation direction of the lever 47. The lock link 49 is provided with a biasing member 51 that constantly biases the lock link 49 in the locking direction. For this reason, the lock link 49 rotates in the locking direction (the direction of the arrow K2 in FIG. 4) by the urging force of the urging member 51, and the unlocking direction (the arrow S2 in FIG. 4) against the urging force of the urging member 51. Direction). As the urging member 51, for example, a torsion spring is used. The lock link 49 and the urging member 51 constitute position holding means.

  In the lock link 49, a restricting portion 52 protrudes at a position shifted from the axis Lb in the plane direction of the lock link 49 (XZ plane direction in FIG. 4). On the other hand, a side portion of the lever 47 is provided with a seat portion 53 on which the restricting portion 52 of the lock link 49 can be placed when the lever 47 is in the unlock position. Further, the seat portion 53 is formed with a locking groove 54 for locking the restriction portion 52 when the lever 47 reaches the lock position. When the restricting portion 52 is caught in the locking groove 54, the locked state of the power plug locking device 33 is maintained. Note that the seat 53 corresponds to a wall.

  A gear portion 55 in which teeth are arranged along the rotation direction of the lock link 49 is provided on a part of the outer periphery of the lock link 49. A power supply plug lock motor 56 is connected to the gear portion 55 as a drive source when the lock bar 41 in the locked state is returned to the unlocked state. The power plug lock motor 56 has a gear portion 57 at the tip of the motor shaft, which meshes with the gear portion 55 of the lock link 49. The power supply plug lock motor 56 is arranged such that the motor shaft is oriented along the apparatus depth direction Y. The power supply plug lock motor 56 is, for example, a DC motor, and is connected to the power source + B of the vehicle 1 via a harness (not shown). When the power supply plug lock motor 56 rotates, the lock link 49 rotates in the direction opposite to that of the power supply plug lock motor 56. The power plug lock motor 56 constitutes a position holding unit.

  The power supply plug lock device 33 is provided with a lock release portion 58 that is used when the power supply plug lock device 33 in the locked state is forcibly released by manual operation (pull operation). The lock release portion 58 has a substantially plate shape and is attached to the case 34 so as to be linearly reciprocable in the apparatus depth direction Y. At the base of the lock release portion 58, for example, a knob portion 59 exposed in the trunk is provided. The lock release part 58 can be operated only from within the trunk by opening the trunk. The lock release part 58 constitutes manual release means.

  The lock release portion 58 is forcibly rotated in the unlocking direction (the direction of arrow S2 in FIG. 4) against the urging force of the urging member 51 when the knob portion 59 is pulled. A slope-shaped link push-up portion 60 to be moved and a lever pushing portion 61 for forcibly turning the lever 47 in the unlocking direction are provided. When the lock release portion 58 is pulled, the link push-up portion 60 rotates the lock link 49 in the unlocking direction by pushing the pushed-in portion 62 of the lock link 49 from above. The pushed-in portion 62 is a protruding portion located on the opposite side of the restricting portion 52 around the pin member 50 in the lock link 49. The lever pushing portion 61 rotates the lever 47 in the unlocking direction by pushing the locking projection 63 on the side wall of the lever 47 when the lock release portion 58 is pulled. The pushed-in portion 62 and the locking protrusion 63 constitute manual release means.

  Between the inner surface of the case 34 and the lock release portion 58, an urging member 64 for returning the retracted lock release portion 58 to its original initial position is interposed. As the urging member 64, for example, a coil spring is used.

  As shown in FIGS. 5 and 6, an unauthorized release prevention mechanism 65 is provided between the case 34 and the lock link 49 to prevent the power plug lock device 33 from being unlocked illegally by an external force. Yes. This is because when the power plug lock device 33 is in a locked state, for example, a third party or the like forcibly pushes the lock bar 41 toward the unlock side with a screwdriver or the like, and forcibly rotates the lock bar 41 in the unlock direction. This is also assumed. If this happens, the power plug locking device 33 is unlocked illegally, and therefore, an unauthorized release prevention mechanism 65 of this example is provided to deal with it.

  The unauthorized release prevention mechanism 65 of this example has a structure in which the outer surface 66 of the lock link 49 having a plate shape is brought into contact with the support surface 67 of the inner wall of the lock body 35 in a wide range. In the case of this example, the direction F of the force generated in the lock link 49 when the lock bar 41 is illegally rotated from the outside in the unlocking direction, and the surface direction of the contact surface of the outer surface 66 and the support surface 67 (see FIG. 5). (XZ plane direction) are orthogonal to each other. Thereby, the tolerance with respect to the unauthorized unlocking of the power supply plug locking device 33 is ensured.

  As shown in FIG. 7, the door lock ECU 13 is connected to an unlock side relay 68 that is turned on when the door is unlocked and a lock relay 69 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 68 and turns on the lock side relay 69 to rotate the door lock motor 14 in the normal 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 68 and turns off the lock side relay 69 to reversely rotate the door lock motor 14.

  The power supply plug lock motor 56 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 power supply plug lock motor 56, a plug lock detection unit 70 for detecting that the power supply plug lock device 33 is in a locked state is connected. The plug lock detection unit 70 is composed of, for example, a micro switch, and is mechanically turned on when the lock mechanism 40 is locked by the turning operation of the lock bar 41. A reverse current prevention diode 71 is connected between the power supply plug lock motor 56 and the plug lock detector 70.

  When the door lock is locked, a current (current Ia in FIG. 7) flows from the lock-side relay 69 to the unlock-side relay 68 in the door lock motor 14. For this reason, since the voltage of the unlocking side terminal 14a of the door lock motor 14 becomes a low potential, no current flows through the power supply plug lock motor 56 regardless of whether the plug lock detector 70 is on or off. The power supply plug lock motor 56 does not operate. 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 68 to the lock side relay 69 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 detector 70 is on, a current flows to the power plug lock motor 56, and the power plug lock device 33 performs the unlock operation. Take.

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, as shown in the figure, the knob part 43 of the lock bar 41 takes the initial position where it is rotated in the direction of the arrow S1 in the figure. Further, the arm contact portion 44 of the lock bar 41 is in an unlock position separated from the lock arm 27. That is, the power plug locking device 33 is unlocked. Therefore, the lock arm 27 can be swung, and the power supply plug 19 can be freely connected to / removed from the inlet 24.

  Further, when the lock bar 41 takes the unlock position, the lever 47 takes the unlock position that has been rotated to the maximum in the direction of the arrow S1 in FIG. At this time, the restriction portion 52 of the lock link 49 is restricted from riding on the seat portion 53 of the lever 47 and rotating in the locking direction. Thereby, the unlocking state of the power plug locking device 33 is maintained.

  As shown in FIG. 9, in order to lock the power feeding plug lock device 33 in the unlocked state, the lock bar 41 in the initial position is held in the locking direction by gripping the knob portion 43 (in the direction of arrow K1 in FIG. 9). To rotate. At this time, the lock bar 41 is rotated until the standing piece 47b abuts against the inner wall surface 34a of the case 34 shown in FIG. 6 against the urging force of the urging member 48. When the lock bar 41 is rotated, the lock bar 41 and the lever 47 are integrally rotated in the direction of the arrow K1 in FIG.

  As shown in FIG. 10, when the lock bar 41 is rotated to the back, the lever 47 is rotated about 30 degrees in the lock direction around the axis La. At this time, the arm contact portion 44 of the lock bar 41 is positioned above the lock arm 27. Therefore, the lock arm 27 locked to the protrusion 32 is pressed from above by the arm contact portion 44 (lock bar 41), and cannot swing. 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.

  Further, when the lever 47 is fully rotated to the lock position, the locking groove 54 of the lever 47 takes a position facing the restriction portion 52 of the lock link 49. For this reason, the restricting portion 52 is released from a state where the position is restricted by the seat portion 53 of the lever 47. Therefore, the lock link 49 rotates in the locking direction (the direction of the arrow K2 in the figure) by the urging force of the urging member 51. Therefore, the restriction portion 52 of the lock link 49 falls into the locking groove 54, and the restriction portion 52 and the locking groove 54 are locked. Thereby, since the rotation of the lever 47 becomes impossible, the locked state of the power plug lock device 33 is maintained. When the lock bar 41 is in the locked position, the plug lock detection unit 70 is mechanically turned on.

  Subsequently, when the unlocking operation of the door lock is executed when the power supply plug locking device 33 is in the locked state, the power supply plug locking device 33 also performs the unlocking operation in conjunction with the door unlocking operation. At this time, as shown in FIG. 11, when the current Ib (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 70 is turned on. Therefore, a part of the current Ib also flows into the power supply plug lock motor 56, and the power supply plug lock motor 56 rotates.

  As shown in FIG. 12, when the power feeding plug lock motor 56 rotates, the motor rotational force is transmitted to the lock link 49 by the gear portions 55 and 57, and the lock link 49 resists the biasing force of the biasing member 51. Rotation starts in the unlocking direction (arrow S2 direction in the figure). At this time, the lock link 49 rotates until it abuts against the inner wall surface (inner bottom surface) 34 b of the case 34.

  When the lock link 49 is fully rotated in the unlocking direction, the lever 47 is released from the state in which the rotation is restricted by the restricting portion 52 of the lock link 49. Therefore, the lever 47 starts to rotate in the unlocking direction (the direction of arrow S1 in FIG. 12) by the urging force of the urging member 48, and the standing piece 47b is placed on the inner surface of the inner wall surface 34c of the case 34 shown in FIG. Rotates until it touches. As the lever 47 rotates in the unlocking direction, the lock bar 41 also rotates in the unlocking direction, the arm contact portion 44 moves away from the lock arm 27, and the knob portion 43 returns to the initial position. As a result, the power plug lock device 33 returns to the unlocked state.

  Here, when the lock state of the power plug lock device 33 cannot be released for some reason, the lock state of the power plug lock device 33 is manually released by operating the lock release portion 58. In addition, since the knob part 59 of the lock release part 58 is arrange | positioned in the trunk of the vehicle 1, the lock | rock manual release of the electric power plug lock apparatus 33 can carry out the electronic key 6, and the authorized user who can unlock a door lock Is only feasible.

  As shown in FIG. 13A, when manually releasing the lock state of the power plug lock device 33, the knob portion 59 of the lock release portion 58 is pulled. As shown in FIG. 13B, in the process of pulling the lock release portion 58, the link push-up portion 60 of the lock release portion 58 moves to push the pushed portion 62 of the lock link 49 downward. When the pushed-in portion 62 is pushed in by the link push-up portion 60, a force in the unlocking direction is applied to the lock link 49, and the lock link 49 starts to rotate in the unlocking direction against the biasing force of the biasing member 51. .

  As shown in FIG. 13C, when the lock release portion 58 is further pulled, the lever pushing portion 61 of the lock release portion 58 pushes the locking protrusion 63 of the lever 47 later. When the lock release portion 58 is further pulled in, the lock release portion 58 moves linearly while pushing the lever 47 later.

  At this time, as shown in FIG. 13 (d), the lever 47 rotates in the unlocking direction while being pushed by the lock release portion 58. When the lever 47 rotates in the unlocking direction, the lock bar 41 also rotates in the unlocking direction, the arm contact portion 44 is separated from the lock arm 27, and the knob portion 43 also returns to the initial position. Therefore, it becomes possible to manually switch the power plug locking device 33 from the locked state to the unlocked state.

  As described above, in this example, since the locking operation of the power supply plug lock device 33 is a manually operated type in which the knob portion 43 is turned, the power supply plug lock device 33 is locked only when it is really necessary. It becomes possible to make it. By the way, if the lock operation of the power supply plug lock device 33 is interlocked with the door lock of the vehicle door, even if the power supply plug 19 is not connected to the inlet 24, every time the door lock operation is performed, the power supply plug The locking device 33 executes the locking operation, leading to early deterioration of the parts. However, in this example, since the power supply plug locking device 33 performs the locking operation only when the knob portion 43 is operated, it is not necessary to cause the power supply plug locking device 33 to perform an unauthorized locking operation, thereby suppressing early deterioration of parts. It becomes possible to do.

  Further, since the power plug locking device 33 of this example integrally forms the knob portion 43 with the lock bar 41, it is not necessary to provide the lock bar 41 (arm contact portion 44) and the knob portion 43 separately. Therefore, even if the power plug lock device 33 is locked by manual operation, the number of parts does not increase, and the structure of the power plug lock device 33 can be simplified.

According to the configuration of the present embodiment, the following effects can be obtained.
(1) The power plug lock device 33 is locked manually by turning the knob 43 of the rotary lock bar 41, and the knob 43 is integrally formed with the lock bar 41.

  (4) The power supply plug lock device 33 is provided with a lock release portion 58 capable of releasing the locked state by manual operation. Therefore, even when the power plug lock device 33 is in the locked state, even if the power plug lock motor 56 does not move for some reason and the lock cannot be released, the lock state can be released by operating the lock release portion 58. Can do. Moreover, since the knob part 59 of the lock release part 58 is arrange | positioned in a trunk, only the authorized user who has the electronic key 6 can operate the lock release part 58 by opening a rank by door lock cancellation | release. Therefore, an illegal manual release operation can also be prevented.

  (5) The lock bar 41 is attached to the lock body 35 attached and fixed to the inlet 24. Therefore, even if a third party applies an external force in the unlocking direction to the knob portion 43 in an attempt to illegally release the locked state of the power plug lock device 33, this force (external release external force) is applied to the inlet 24. The lock body 35 can be received firmly. Therefore, even when an external force for unauthorized release is applied to the knob portion 43, the case 34 can be prevented from being broken from the lock bar 41 by this external force, so that unauthorized unlocking can be prevented.

  (6) The unlocking operation of the power supply plug locking device 33 is interlocked with the unlocking operation of the vehicle door. For this reason, when the power feeding plug lock device 33 is switched to the unlocked state, a special operation is not required separately, so that convenience can be improved.

  (7) The power plug lock device 33 is provided with the unauthorized release prevention mechanism 65 by bringing the outer surface 66 of the lock link 49 into contact with the support surface 67 of the case 34 over a wide range. For this reason, even if a third party applies an external force in the unlocking direction to the knob portion 43 in an attempt to illegally release the locked state of the power plug lock device 33, this force (external release external force) is applied to the support surface 67. Since it can be received, unauthorized unlocking can be made difficult to occur.

  (8) When the lock bar 41 (knob portion 43), the lever 47, and the lock link 49 are operated, they are in contact with the inner wall of the case 34 so that the movement stops (positions). Therefore, since the sensor etc. which monitor the position of each member are unnecessary, an apparatus structure can be simplified.
