Abstract

PROBLEM TO BE SOLVED: To provide a lock device for electric power supply capable of fixing a charge connector to a main body with high certainty.SOLUTION: In the lock for electric power supply, a lock body 15 is displaced to a latch position by displacing a switch lever 21 from an unlock position to a lock position. In this case, a pole 17 that is provided separately from the switch lever 21 is displaced to a block position and the pole 17 blocks displacement of the lock body 15 from the latch position to an unlatch position. Thus, the lock body 15 keeps the latch position. On the other hand, the pole 17 is displaced to an unblock position by displacing the switch lever 21 from the lock position to the unlock position, and the pole 17 allows the lock body 15 to be displaced from the latch position to the unlatch position. Thus, in the lock for electric power supply, the lock body 15 keeps the latch position as long as the pole 17 is located at the block position.SELECTED DRAWING: Figure 5

Description

  The present invention relates to a power supply locking device.

  In recent years, many electric vehicles and hybrid vehicles that can run with electric power stored in a battery have been put into practical use. In such an electric vehicle or the like, it is necessary for a user or the like to charge the battery by connecting the charger and the vehicle body with a charging cable due to a decrease in the amount of electricity stored in the battery. In general, a port and an engaging portion are formed in a vehicle body that is a main body. On the other hand, the charging cable includes a charging connector in which a connector portion and an engaged portion are formed, and a cable that electrically connects the charger and the charging connector. When charging the battery, the engaging portion of the vehicle body and the engaged portion of the charging connector are engaged while inserting the connector portion of the charging connector into the port of the vehicle body. As a result, the charger and the vehicle body are connected by the charging cable, and the battery is charged by the charger.

  By the way, since it takes a relatively long time to charge the battery, the user or the like may leave the electric vehicle or the like during the charging. At this time, for example, there is a concern that a malicious person intentionally removes the charging connector and steals power, or steals the charging cable. Therefore, a power feeding lock device for fixing the charging connector to the main body, which is a vehicle body or a charger, is required.

  Such a power supply locking device is disclosed in Patent Document 1, for example. This power supply locking device includes a base member, a lock body, and an operating mechanism. In this power supply locking device, the vehicle body is a main body, and a port and an engaging portion are formed in the vehicle body. The base member is fixed to the vehicle body. The lock body is swingably provided on the base member. The lock body is displaceable between a latch position that holds the engagement between the engaging portion and the engaged portion, and an unlatched position that allows the engaged portion to be disengaged from the engaging portion. The operating mechanism is displaced between a lock position and an unlock position when the user or the like performs a lock operation or an unlock operation on the operation unit.

  Specifically, the operating mechanism includes a motor, a worm provided on the output shaft of the motor, a worm wheel that meshes with the worm, and a drive gear that is coaxial with the worm wheel. In this power feeding lock device, when the operation portion is locked while the engaging portion and the engaged portion are engaged while the connector portion is inserted into the port, the drive gear swings in the first direction. The unlocked position is displaced to the locked position swung in the second direction. Thereby, the lock body is switched from the unlatched position to the latched position. Thus, in this power feeding lock device, the engagement between the engaging portion and the engaged portion is maintained, and the charging connector is fixed to the vehicle body. For this reason, even if the user or the like is away from the electric vehicle or the like during charging, theft or the like can be prevented.

  On the other hand, when the charging of the battery is completed and the unlocking operation is performed on the operation unit, the drive gear is displaced from the lock position swinging in the second direction to the unlock position swinging in the first direction. Thereby, the lock body is switched from the latch position to the unlatched position. Thus, in this power supply locking device, the engaging portion and the engaged portion can be detached, and the charging connector can be separated from the vehicle body.

JP 2013-74702 A

  However, in the conventional power supply locking device, the motor, the worm, the worm wheel, and the drive which are the components of the operating mechanism in a state where the engaging portion and the engaged portion are engaged while the connector portion is inserted into the port. The gear is directly connected to the lock body, so that the lock body is maintained in the latched position. For this reason, in the state where the connector part is inserted into the port, a malicious person uses it as a tool, forcibly displaces the lock body from the latched position to the unlatched position against the resistance of the components of the operating mechanism, There is a risk of removing the connector.

  The present invention has been made in view of the above-described conventional situation, and an object to be solved is to provide a power supply locking device that can fix the charging connector to the main body with high reliability.

The power supply locking device of the present invention is a charger or a vehicle body, and is used between a main body in which a port and an engaging portion are formed and a charging connector in which a connector portion and an engaged portion are formed. A power supply locking device for fixing the charging connector to the main body in a state where the engaging portion and the engaged portion are engaged while inserting the connector portion,
The power supply locking device includes a base member fixed to the main body,
A latch position that is swingably provided on the base member and holds the engagement between the engaging portion and the engaged portion, and an unlatching that allows the engaged portion to be detached from the engaging portion. A locking body that is displaceable between positions;
The lock body is displaced from the unlock position to the lock position by a lock operation to the operation section, and the lock body is switched from the unlock position to the latch position. The unlock operation to the operation section is displaced from the lock position to the unlock position. And an operation mechanism for switching the lock body from the latch position to the unlatch position;
A block position provided on the base member so as to be swingable, and blocking the displacement of the lock body from the latch position to the unlock position when the operating mechanism is displaced from the unlock position to the lock position; A pole that is displaceable between an unlocking position that allows the locking body to be displaced from the latching position to the unlocking position when the actuating mechanism is displaced from the locking position to the unlocking position. It is characterized by having.

  In the power supply locking device according to the present invention, if the locking operation is performed on the operation portion in a state where the engaging portion and the engaged portion are engaged while the connector portion is inserted into the port, the operating mechanism is moved from the unlock position. By displacing to the lock position, the pole is displaced to the block position, and the pole blocks the lock body from displacing from the latch position to the unlatching position. Thus, in this power supply locking device, the engagement between the engaging portion and the engaged portion is maintained, and the charging connector is fixed to the main body. For this reason, even if the user or the like is away from the electric vehicle or the like during charging, theft or the like can be prevented.

  In this state, in this power feeding lock device, a pole different from the operating mechanism is displaced to the block position, and the lock body is maintained at the latch position. For this reason, even if a malicious person attempts to displace the lock body from the latch position to the unlatching position with a tool or the like when the connector portion is inserted into the port, the lock body is latched as long as the pole is in the block position. The charging connector cannot be removed because it can be maintained in position.

  On the other hand, when the charging of the battery is completed and the operation unit is unlocked, the operating mechanism is displaced from the locked position to the unlocked position, so that the pole is displaced to the unblocked position, and the pole is latched by the lock body. Allow displacement from position to unlatched position. Thus, in this power supply locking device, the engaging portion and the engaged portion can be detached, and the charging connector can be separated from the main body.

  Therefore, according to the power supply locking device of the present invention, the charging connector can be fixed to the main body with high reliability.

  In this power supply locking device, the pole displaced to the block position maintains the lock body at the latch position as described above. Therefore, for example, even when the unlocking operation is performed on the operation unit in a state where the lock body is constrained by the engaging portion or the engaged portion, the operating mechanism is moved from the lock position independently of the lock body. It can be displaced to the unlock position. Also, the pole can be displaced to the unlocked position independently of the lock body by the operation mechanism being displaced to the unlocked position.

  In the power supply locking device of the present invention, various configurations can be adopted as the operating mechanism. The operation unit may be a switch or a lever that is locked or unlocked by a user or the like. Further, the operating mechanism may have a manually operated key cylinder in addition to an actuator such as a motor and a solenoid driven by a locking operation or an unlocking operation to the operation unit. In addition, this actuating mechanism switches the lock body from the unlatched position to the latched position, switches the pole from the unblocked position to the block position, switches the pole from the block position to the unblocked position, and locks it. You may have an open lever which can switch a body from a latch position to an unlatching position.

  The lock body is preferably biased from the latch position to the unlatching position. The pole is preferably biased from the unblock position to the block position. The urging means for urging the lock body and the urging means for urging the pole may be separate or one.

  The operating mechanism preferably has a switching lever provided on the base member so as to be swingable between a locked position and an unlocked position. The switching lever can be swung from the unlock position to the lock position by a lock operation to switch the lock body from the unlatch position to the latch position and to displace the pole from the unblock position to the block position. Further, the switching lever can swing from the unlock position to the lock position by the unlocking operation, displace the pole from the block position to the unlock position, and switch the lock body from the latch position to the unlock position.

  In this case, by displacing one switching lever between the lock position and the unlock position, the lock body can be switched between the latch position and the unlatch position, and the pole can be switched between the block position and the unblock position. You can switch to Thereby, in this power supply locking device, the configuration can be simplified, and downsizing and cost reduction can be realized.

  The lock body is preferably provided with a torsion coil spring that urges the lock body and the pole coaxially. In this case, the lock body can be urged from the latch position to the unlatch position by one torsion coil spring, and the pole can be urged from the unblock position to the block position. Thereby, in this power supply locking device, the number of parts can be reduced. In addition, since the torsion coil spring is provided on the base member coaxially with the lock body and the switching lever, it is possible to more suitably achieve downsizing.

  The switching lever may be provided on the base member separately from the lock body and the pole. The switching lever is preferably provided coaxially with the lock body. In this case, the base member can be reduced in size, and the power supply locking device can be further reduced in size.

  In the power supply locking device according to the present invention, the main body may be a vehicle body capable of exposing the port to the outside of the passenger compartment. The operating mechanism is connected to the switching lever and extends from the outside of the passenger compartment to the inside of the passenger compartment, a sealing member that inserts the connecting member and seals the outside of the passenger compartment and the passenger compartment, and is provided in the passenger compartment. It is preferable to have an actuator that is connected to the connecting member and swings the switching lever between the lock position and the unlock position.

  In this case, the actuator can be operated to swing the switching lever between the locked position and the unlocked position. Here, the actuator is provided in the vehicle interior, and is connected to the switching lever by a connecting member. The connecting member is provided with a sealing member. Thereby, the exterior of the passenger compartment and the passenger compartment can be sealed, and rainwater and the like can be suitably prevented from entering the passenger compartment.

  As the connecting member, for example, a rod or a cable can be employed. Further, as the sealing member, for example, a rubber boot through which a rod or cable is inserted can be employed. The boot preferably includes a main body portion that is held in an opening that communicates the outside of the vehicle compartment and the vehicle interior, and a bellows portion that is formed integrally with the main body portion and expands and contracts when the switching lever is displaced.

  Moreover, it is preferable that the lock body is provided so as to be able to swing in a plane substantially orthogonal to the insertion direction of the connector portion with respect to the port. In this case, the power supply locking device can be reduced in size in the insertion direction of the connector portion.

  According to the power supply locking device of the present invention, the charging connector can be fixed to the main body with high reliability.

  Here, the swinging direction when the switching lever 21 is displaced between the unlock position and the lock position is the vertical direction of the power supply locking device. On the other hand, the swing direction when the lock body 15 is displaced between the latch position and the unlatch position and the swing direction when the pole 17 is displaced between the block position and the unblock position are: This is the front-rear direction of the power supply locking device. That is, the lock body 15 and the pole 17 swing in a virtual plane substantially orthogonal to the insertion direction of the connector portion 9a with respect to the port 7a.

  When the lock body 15 is displaced to the latch position, the main body portion 15a is positioned at the approximate center in the front-rear direction in the engagement hole 111 as shown in FIG. On the other hand, when the lock body 15 is displaced to the unlatched position, the main body portion 15a moves to the rear side in the engagement hole 111 as shown in FIG. Further, in a state where the switching lever 21 is displaced to the unlock position, the cylindrical portion 21 d comes into contact with the contact portion 17 b of the pole 17. Thereby, the pole 17 is restricted from being displaced from the unblock position to the block position. That is, in a state where the switching lever 21 is displaced to the unlock position, the pole 17 maintains the unlocked position.

  The actuator 29 shown in FIG. 4 has a case 29a that houses a motor (not shown), and a swing part 29b that is swingably attached to the case 29a. A connecting portion 29c is provided at the rear end of the case 29a. The connection unit 29c is electrically connected to the control device 101 shown in FIG. As shown in FIG. 4, fixing portions 29d and 29e for fixing the actuator 29 to a body panel (not shown) are formed on the upper end side and the lower end side of the case 29a, respectively.

  The control device 101 illustrated in FIG. 2 is electrically connected to the lock switch 103. When the lock switch 103 is turned on, the user performs a lock operation, and when the lock switch 103 is turned off, the user performs an unlock operation. The control device 101 transmits a lock start signal to the motor of the actuator 29 if the lock switch 103 is in the ON state, and transmits a lock release signal to the motor if the lock switch 103 is in the OFF state. Thereby, in the actuator 29, the rocking | swiveling part 29b moves up and down. The control device 101 and the lock switch 103 may be wirelessly connected.

  As shown in FIG. 4, the rod 31 extends in the vertical direction of the power feeding lock device. The upper end side of the rod 31 is attached to the swing part 29b. On the other hand, a flange 31a is formed on the lower end side of the rod 31, as shown in FIG. A male screw 31 b is formed at the lower end of the rod 31.

  A fixed groove 330 that is annular in the horizontal direction is formed on the outer peripheral surface of the main body 33a. By fitting the body panel 11 a into the fixing groove 330, the main body portion 33 a is held in the opening 110. The boot 33a can be expanded and contracted in the vertical direction by the bellows portion 33b. In addition, a flange fixing groove 331 having an annular shape in the horizontal direction is recessed inside the lower end of the bellows portion 33b.

  The rod 31 is inserted into the insertion hole 33 c of the boot 33. At this time, the flange 31 a of the rod 31 is fitted into the flange fixing groove 331. Thereby, the rod 31 is assembled | attached to the boot 33 in the state which made the male screw 31b protrude from the lower end side of the bellows part 33b.

  The connection block 35 has a main body portion 35a having a substantially rectangular shape, and a fixed claw portion 35b formed integrally with the main body portion 35a. A female screw 35c that can be screwed with the male screw 31b of the rod 31 is formed in the main body portion 35a. When the male screw 31b of the rod 31 is screwed into the female screw 35c, the main body portion 35a and the rod 31 are fixed without performing separate bonding or the like. Thus, the rod 31 and the connection block 35 are connected.

  The connecting block 35 is assembled to the switching lever 21 by fixing the fixing claw portion 35b in the second insertion hole 21b of the connecting lever 21 shown in FIG. Thus, the actuator 29 and the switching lever 21 are connected through the rod 31 and the connecting block 35, and the vertical movement of the swinging portion 29 b can be transmitted to the switching lever 21.

  The power supply locking device configured as described above operates as follows when the battery of the electric vehicle 1 is charged. Here, in the state where the battery is not charged by the charger 3, that is, when the connector portion 9 a is not inserted into the port 7 a shown in FIG. 3, the user locks the power supply locking device shown in FIG. 2. The switch 103 is turned off. Therefore, as shown in FIG. 8, the lock body 15 is displaced to the unlatched position by the first biasing force of the torsion coil spring 19, and the main body portion 15a of the lock body 15 is inserted into the insertion hole as described above. 111 is in a state of moving to the rear side. Further, the pole 17 is displaced to the unlocked position, and the switching lever 21 is displaced to the unlocked position.

  When the battery of the electric vehicle 1 is charged by the charger 3, the user connects the second charging connector portion 90 c of the charging cable 9 to the connecting portion of the charger 3 as shown in FIG. 1. In addition, the user inserts the connector portion 9 a of the first charging connector 90 b into the port 7 a of the female connector 7. At this time, as shown in FIG. 3, the claw portion 901 of the operation lever 9b enters the inside of the vehicle interior through the engagement hole 111. And the convex part 7b and the recessed part 901a of the nail | claw part 901 engage in the engagement hole 111. FIG. Thus, in the port 7a, the contact part 70 and the connector part 9a are electrically connected, and charging of the battery by the charger 3 is started through the charging cable 9.

  Here, in this power supply locking device, since the lock body 15 is displaced to the unlatched position as described above, when the connector portion 9a is inserted into the port 7a, the claw portion 901 and the lock portion 901 are locked. The main body 15a of the body 15 does not come into contact. For this reason, it is prevented suitably that the nail | claw part 901 and the main-body part 15a are damaged.

  Thus, after inserting the connector portion 9a into the port 7a, the user performs a locking operation by turning on the lock switch 103 shown in FIG. As a result, the control device 101 transmits a lock start signal. For this reason, in the actuator 29, the motor operates and the swinging portion 29b swings downward. For this reason, the rear end side of the switching lever 21 is pushed downward through the rod 31 and the connecting block 35. As a result, the switching lever 21 swings around the first pin 25 and starts to be displaced from the unlock position shown in FIG. 8 toward the lock position as indicated by the broken line arrow in FIG. At this time, the boot 33 extends downward. 8 to 11, the rod 31 and the connection block 35 are not shown for ease of explanation.

  When the switching lever 21 starts to be displaced toward the lock position, the pressing surface 21 c of the switching lever 21 presses the pressed surface 15 d of the lock body 15. As a result, the lock body 15 swings against the first urging force of the torsion coil spring 19 and starts to be displaced from the unlatched position to the latched position, as indicated by the broken line arrow in FIG.

  Further, in the pole 17, the contact portion 17 b and the cylindrical portion 21 d of the switching lever 21 do not contact each other because the switching lever 21 starts to be displaced toward the lock position. For this reason, the restriction by the switching lever 21 is released, and the pole 17 starts to be displaced from the unblock position to the block position by the second urging force of the torsion coil spring 19 as indicated by the broken line arrow in FIG.

  Then, as shown in FIG. 10, when the switching lever 21 is displaced to the lock position, the lock body 15 is switched to the latch position. Further, when the pole 17 is displaced to the block position, the latch surface 15c of the lock body 15 and the stopper surface 17c of the pole 17 are engaged. Thereby, the pole 17 displaced to the block position blocks the lock body 15 from being displaced from the latch position to the unlatched position. For this reason, the lock body 15 maintains the latch position.

  When the lock body 15 is displaced to the latch position, the main body portion 15 a is positioned almost immediately above the claw portion 901 in the engagement hole 111. For this reason, when the lock body 15 is displaced to the latch position, the main body portion 15a restricts the upward swing of the claw portion. For this reason, even if the user or a third party presses the button portion 902 of the operation lever 9b shown in FIG. 3, the claw portion 901 can only slightly swing upward in the insertion hole 111. The engagement between the convex portion 7b and the concave portion 901a cannot be released.

  Thus, the state where the convex portion 7b and the concave portion 901a are engaged with each other is held by the power supply lock device while the battery is being charged, and the first charging connector 90b is fixed to the female connector 7 and eventually the vehicle body 1a.

  On the other hand, after the charging of the battery is completed, the user performs an unlocking operation by turning off the lock switch 103 shown in FIG. As a result, the control device 101 transmits a lock release signal. Thereby, in the actuator 29, the motor operates, and the swing part 29b swings upward. For this reason, the rear end side of the switching lever 21 is pushed upward through the rod 31 and the connecting block 35. As a result, the switching lever 21 swings around the first pin 25 and starts to be displaced from the locked position shown in FIG. 10 to the unlocked position as indicated by the dashed arrow in FIG. At this time, the boot 33 is compressed upward.

When the switching lever 21 starts to be displaced toward the unlock position, the pressing surface 21c and the pressed surface 15d of the lock body 15 do not come into contact with each other, and the pressing surface 21c is pressed 15d.
Will not press. Further, the cylindrical portion 21d of the switching lever 21 contacts the contact portion 17b of the pole 17, and pushes the contact portion 17b upward. As a result, the pole 17 starts to be displaced from the block position to the unblock position against the second urging force of the torsion coil spring 19 as indicated by the broken line arrow in FIG. For this reason, the engagement between the stopper surface 17c and the latch surface 15c is released, and the lock body 15 starts to be displaced from the latch position to the unlatched position by the first biasing force of the torsion coil spring 19. That is, when the pole 17 is displaced to the unblock position, the lock body 15 is allowed to be displaced from the latch position to the unlatch position.

  Then, as shown in FIG. 8, when the switching lever 21 is displaced to the unlock position, the lock body 15 is switched to the unlock position. At this time, in the lock body 15, the stopper member 23 comes into contact with the contact piece 13 f of the base plate 13. This prevents the lock body 15 from further swinging beyond the unlatched position. Further, since the stopper member 23 abuts against the abutting piece 13f, the impact and impact sound at the abutment are reduced as compared with the case where the lock body 15 abuts directly on the abutting piece 13f.

  In this way, the lock body 15 is switched to the unlatched position, so that the main body portion 15a moves backward in the engagement hole 111. For this reason, when the user presses the button part 902 shown in FIG. 3, the claw part 901 can swing upward. Thereby, the engagement between the convex portion 7b and the concave portion 901 is released, and the concave portion 901a is allowed to be detached from the convex portion 7b.

  In this way, the user pulls out the first charging connector 90b to the outside of the passenger compartment while pressing the button portion 902, thereby causing the connector portion 9a to escape from the port 7a, so that the first charging connector 90b and the female connector 7 are connected. The connection can be released. The user also releases the connection between the charger 3 and the charging cable 9 by pulling out the second charging connector 90 c from the connecting portion of the charger 3.

  Further, when the switching lever 21 is displaced to the unlock position, the pole 17 is displaced to the unlock position. And since the state which the cylindrical part 21 of the switching lever 21 and the contact part 17b of the pole 17 contact | abutted is maintained, the pole 17 displaced to the unblock position will be displaced to a block position as mentioned above. Is regulated.

  As described above, in this power feeding locking device, when the locking operation is performed with the lock switch 103 in the ON state in a state where the convex portion 7b and the concave portion 901a are engaged while the connector portion 9a is inserted into the port 7a, The switching lever 21 is displaced from the unlock position to the lock position. Thereby, the pole 17 is displaced to the block position, and the pole 17 blocks the displacement of the lock body 15 from the latch position to the unlatched position. Thus, in this power supply locking device, the engagement between the convex portion 7b and the concave portion 901a is maintained, and the first charging connector 90b is fixed to the vehicle body 1a. For this reason, even if the user or the like is away from the electric vehicle 1 during charging, theft or the like can be prevented.

  In this state, in this power supply locking device, a pole 17 different from the switching lever 21 is displaced to the block position and maintains the lock body 15 at the latch position. The actuator 29, the rod 31 and the switching lever 21 are not directly connected to the lock body 15. Therefore, in the state where the connector portion 9a is inserted into the port 7a, even if a malicious person tries to displace the lock body 15 from the latched position to the unlatched position with a tool or the like, as long as the pole 17 is in the block position, Since the lock body 15 can be maintained in the latched position, the first charging connector 90b cannot be removed.

  On the other hand, when the charging of the battery is completed and the unlocking operation is performed with the lock switch 103 turned off, the switching lever 21 is displaced from the locked position to the unlocked position. Thereby, the pole 17 is displaced to the unblocked position, and the pole 17 allows the lock body 15 to be displaced from the latched position to the unlatched position. Thus, in this power supply locking device, the convex portion 7b and the concave portion 901a can be detached, and the first charging connector 90b can be separated from the vehicle body 1a.

  Therefore, according to the power supply locking device of the embodiment, the first charging connector 90b can be fixed to the vehicle body 1a with high reliability.

  Here, in this power supply locking device, for example, when the user presses the button part 902 before performing the unlocking operation, as shown by the solid line arrow in FIG. The swinging claw portion 901 can come into contact with the main body portion 15a of the lock body 15, and the lock body 15 can be restrained by the claw portion 901. Thereby, the lock body 15 is restricted from being displaced from the latch position to the unlatch position.

  In this respect, in this power supply locking device, the pole 17 displaced to the block position maintains the lock body 15 at the latch position as described above. For this reason, even if the unlocking operation is performed in a state where the lock body 15 is restrained by the claw portion 901, the switching lever 21 is displaced from the lock position to the unlock position independently of the lock body 15. Therefore, an unnecessary load does not act on the motor or the like of the actuator 29. The pole 17 can also be displaced from the block position to the unlocked position independently of the lock body 15 by the displacement of the switching lever 21 to the unlocked position. The lock body 15 can be displaced from the latched position to the unlatched position by the first urging force of the torsion coil spring 19 when the restriction by the claw portion 901 is released.

  In this power supply locking device, the lock body 15 can be switched between the latch position and the unlock position by displacing one switching lever 21 between the lock position and the unlock position. It is possible to switch between a block position and an unblock position. Further, in this power supply locking device, the lock body 15 can be biased toward the unlatched position and the pole 17 can be biased toward the block position by one torsion coil spring 19. As a result, in this power supply locking device, the number of parts can be reduced and the cost can be reduced.

  In this power supply locking device, the switching lever 21, the lock body 15, and the torsion coil spring 19 are coaxially provided on the base plate 13. For this reason, in this power supply lock, the pace plate 13 can be reduced in size.

  Further, in this power supply locking device, the lock body 15 and the pole 17 are provided so as to be swingable in a virtual plane substantially orthogonal to the insertion direction of the connector portion 9a with respect to the port 7a. For this reason, this power supply lock can be downsized in the insertion direction of the connector portion 9a, that is, in the depth direction of the power supply lock device. For these reasons, the power supply locking device can increase the degree of freedom in designing the vehicle body 1a to be attached.

  Further, in this power feeding lock device, the switching lever 21 can be swung between the lock position and the unlock position by the operation of the actuator 29. Therefore, in this power supply locking device, if the user turns the lock switch 103 ON or OFF, thereafter, the switching lever 21 is automatically displaced from the unlock position to the lock position or unlocked from the lock position. It can be displaced to the lock position.

  Here, the actuator 29 is provided in the vehicle interior, that is, inside the body panel 11a, and the switching lever 21 provided on the base plate 13 is located outside the body panel 11a. The actuator 29 and the switching lever 21 are connected by a rod 31 and a connecting block 35. Since this rod 31 is provided with a boot 33, it is possible to seal the outside of the passenger compartment and the passenger compartment. Thereby, it is possible to suitably prevent rainwater or the like from entering the vehicle interior through the opening 110 of the body panel 11a. Moreover, since the bellows part 33b is formed in the boot 33, it can deform | transform suitably according to the vertical motion of the rod 31. FIG.

  Further, in the lock body 15 in the power supply locking device, the main body portion 15a has a substantially rectangular shape, and the outside of the passenger compartment is formed in a step shape extending vertically in the vertical direction. For this reason, when the lock body 15 is displaced to the latch position, the main body portion 15 a is in a state of closing the inside of the insertion hole 111. For this reason, even if the user tries to insert the connector portion 9a into the port 7a while the lock switch 103 is in the ON state, the user recognizes that the main body portion 15a cannot be moved depending on the claw portion 901. Easy to do. Also in this respect, in this power supply locking device, the claw portion 901 and the main body portion 15a are preferably prevented from being damaged.

  While the present invention has been described with reference to the embodiments, it is needless to say that the present invention is not limited to the above-described embodiments and can be appropriately modified and applied without departing from the spirit thereof.

  For example, the power supply lock device may be provided in the charger 3, and the second charge connector 90c inserted into the connection portion of the charger 3 and the charger 3 may be fixed by the power supply lock device.

  In addition, instead of the actuator 29, a key cylinder that operates by locking and unlocking is connected to the switching lever 21, and the user locks the key cylinder as a locking operation or unlocks the key cylinder as an unlocking operation. The switching lever 21 may be displaced between the unlock position and the lock position.

  The present invention can be used for an electric vehicle, a hybrid vehicle, and a charging facility.
