The rail 52 extends horizontally along the ceiling portion 51. Therefore, the transport unit 59 is provided so as to be movable in the horizontal direction. The transport unit 59 moves together with the charger-side connector 33 and the charger-side guide 41. The support column 53 supports the ceiling portion 51 and is rotatable in the circumferential direction.

The spring 58 is connected to the charger-side connector 33 and the support column 53. The spring 58 expands due to the force due to the movement of the charger side connector 33 and the charger side guide 41, and contracts due to the restoring force when released from the force applied from the charger side connector 33 and the charger side guide 41. When the spring 58 contracts, the charger-side connector 33 and the charger-side guide 41 are located at predetermined positions. The spring 58 positions the charger-side connector 33 and the charger-side guide 41 at predetermined positions when the force from the charger-side connector 33 and the charger-side guide 41 is not applied. The predetermined position is a place where the charger-side connector 33 and the charger-side guide 41 are arranged when the spring 58 contracts due to the restoring force acting on the spring 58, and is a substantially constant position.

The charger 30 includes a wire 43, a reel 44 around which the wire 43 is wound, and a motor 45 that rotates the reel 44. The wire 43, the reel 44, and the motor 45 are built in the charger side guide 41. A part of the wire 43 projects from the tip of the charger-side guide 41 to the outside of the charger-side guide 41. When the wire 43 is pulled, the reel 44 rotates and the wire 43 is pulled out from the reel 44. It can be said that the wire 43 is provided so that it can be pulled out. When the motor 45 is driven, the reel 44 rotates and the reel 44 is wound around the wire 43. The reel 44 and the motor 45 function as a winding unit that winds the wire 43. The drive of the motor 45 is controlled by the control device 31.

As shown in FIG. 3, the wire 43 is provided with a concave portion 47 at the tip portion which is recessed in a direction orthogonal to the axial direction of the wire 43. The wire 43 has a lock mechanism 60 at its tip. The lock mechanism 60 includes a claw portion 61, a hinge 62 that rotatably supports the claw portion 61, a solenoid actuator 63, a wire 65 for driving the solenoid actuator 63, and a biasing spring 66. Prepare

By rotating the claw 61 about the hinge 62, the amount of protrusion from the recess 47 in the direction orthogonal to the axial direction of the wire 43 changes. The claw portion 61 is biased by a biasing spring 66 in a direction of protruding from the recess 47. The plunger 64 of the solenoid actuator 63 is fixed to the claw portion 61. The movement of the plunger 64 due to the energization of the solenoid actuator 63 causes the pawl portion 61 to rotate about the hinge 62 so as to be housed in the recess 47. When the solenoid actuator 63 is de-energized, the urging force of the urging spring 66 causes the claw portion 61 to rotate about the hinge 62 so as to project from the recess 47. That is, the amount of protrusion of the claw portion 61 from the recess 47 can be changed by switching between energization of the solenoid actuator 63 and interruption of energization.

The wiring 65 is a conducting wire for energizing the solenoid actuator 63. The wiring 65 extends through the wire 43 to the solenoid actuator 63. The control device 31 controls energization and interruption of energization of the solenoid actuator 63.

When the wire 43 is inserted into the second recess 24 while the solenoid actuator 63 is not energized, the claw 61 is inserted into the retaining recess 26. When the claw 61 is hooked on the first hooking surface 27, the wire 43 is in a locked state in which the wire 43 is restricted from being pulled out from the second recess 24. Therefore, the first hooking surface 27 functions as a hooking portion on which the claw portion 61 is hooked. When the solenoid actuator 63 is energized, the claw portion 61 enters the recess 47. As a result, the claw portion 61 hooked on the first hooking surface 27 is removed from the first hooking surface 27, and the wire 43 is unlocked. When the wire 43 is unlocked, the wire 43 can be extracted from the second recess 24.

The operation of this embodiment will be described.
As shown in FIG. 4, when charging is performed using the charger 30, the operator of the charger 30 pulls the wire 43 to pull out the wire 43 from the charger side guide 41. Then, the operator inserts the drawn wire 43 into the second recess 24. When the wire 43 is inserted into the second recess 24, the claw 61 enters the hooking recess 26. The wire 43 is locked by the hook portion 61 hooking on the first hooking surface 27.

As shown in FIG. 5, when the wire 43 is locked, the wire 43 is wound around the reel 44 by driving the motor 45. The charger side guide 41 is pulled by the wire 43. When this force acts on the transport unit 59, the charger-side connector 33 and the charger-side guide 41 move together with the transport unit 59 so as to approach the vehicle 10. The first recess 22 of the vehicle-side guide 21 has a larger diameter toward the outside of the vehicle, and the charger-side guide 41 has a smaller diameter toward the tip thereof. Easy to enter. When a part of the charger-side guide 41 enters the first recess 22, the charger-side guide 41 is fitted to the vehicle-side guide 21 by the guidance of the first section screen 23. The fitting of the vehicle side guide 21 and the charger side guide 41 guides the charger side connector 33 to the vehicle side connector 12. Then, the vehicle side connector 12 and the charger side connector 33 are connected.

In addition, the driving of the motor 45 is provided with a detection unit that detects that the wire 43 is inserted into the second recess 24, and is automatically performed by the control device 31 when the detection by the detection unit is performed. Good. Further, the motor 45 may be driven by an operator operating an operation unit such as a switch.

When the vehicle side connector 12 and the charger side connector 33 are connected, charging of the battery B is started. When the vehicle side connector 12 and the charger side connector 33 are connected, the connection between the control device 31 and the ECU 11 is established. The control device 31 may start the charging when the connection with the ECU 11 is established and the charging start command is received from the ECU 11. Charging may be started by an operator operating an operation unit such as a switch.

The control device 31 ends charging when the battery B is fully charged. The ECU 11 grasps the charging rate of the battery B from the detection result of the voltage sensor or the like. When the battery B is fully charged, the ECU 11 transmits a charge stop command to the control device 31. When the control device 31 receives the charge stop command, the control device 31 ends the charge.

When the charging of the battery B is completed, the control device 31 drives the solenoid actuator 63 to remove the claw portion 61 hooked on the first hooking surface 27. As a result, the wire 43 is unlocked. The solenoid actuator 63 and the control device 31 that controls the solenoid actuator 63 function as a hook release portion that removes the claw portion 61 from the first hook surface 27 when the charging of the battery B is completed. When the wire 43 is unlocked and the charger side connector 33 is detached from the vehicle side connector 12, the stretched spring 58 contracts due to the restoring force, so that the charger side connector 33 and the charger side guide. 41 returns to a predetermined position. The spring 58 functions as a moving unit that moves the charger-side connector 33 and the charger-side guide 41 to predetermined positions when the wire 43 is not hooked on the first hooking surface 27.

The effects of this embodiment will be described.
(1) Since the charger side connector 33 is connected to the vehicle side connector 12 by winding the wire 43 hooked on the first hooking surface 27 around the reel 44, the charger side connector 33 and the vehicle side connector 12 are connected. Can be easily connected. The operator can connect the charger side connector 33 to the vehicle side connector 12 by inserting the wire 43 into the second recess 24 without lifting the charger side connector 33. Therefore, as compared with the case where the charger side connector 33 is directly connected to the vehicle side connector 12, the labor of the operator who performs charging is reduced.

(2) The charger 30 is provided with the wire 43, the reel 44, and the motor 45. Compared with the case where the wires 43, the reels 44, and the motors 45 are individually provided for each vehicle 10, the required numbers of the wires 43, the reels 44, and the motors 45 are reduced, and the charging system CS can be configured at low cost.

(3) When the charging of the battery B is completed, the claw portion 61 hooked on the first hooking surface 27 by the solenoid actuator 63 is removed from the first hooking surface 27. Therefore, after the charging of the battery B is completed, the wire 43 hung on the first hooking surface 27 is automatically removed, so that the operator operates to remove the claw portion 61 from the first hooking surface 27. No need to do. Therefore, the burden on the operator can be reduced.

(4) A spring 58 that connects the support column 53 and the charger-side connector 33 is provided. When the claw portion 61 is removed from the first hooking surface 27 after charging the battery B, the charger-side connector 33 and the charger-side guide 41 return to the predetermined positions. Therefore, it is not necessary for the operator to return the charger side connector 33 and the charger side guide 41 to the predetermined positions after the charging of the battery B is completed, and the burden on the operator can be reduced.

The embodiment can be modified and implemented as follows. The embodiment and the following modifications can be implemented in combination with each other within a technically consistent range.
As shown in FIGS. 6 and 7, the charger-side guide 81 may include the first recess 22 and the second recess 24, and the vehicle-side guide 71 may include the insertion portion 42 that is inserted into the first recess 22. Good. That is, the male-female relationship between the charger side guide 41 and the vehicle side guide 21 of the embodiment may be reversed.

Further, the wire 43, the reel 44 and the motor 45 may be provided on the vehicle side guide 71. In this case, the charger side guide 81 is provided with the first hooking surface 27 and the second hooking surface 28 for hooking the wire 43. That is, one of the vehicle 10 and the charger 30 includes the wire 43, the reel 44, and the motor 45, and the other of the vehicle 10 and the charger 30 includes the first hooking surface 27 for hooking the wire 43. It should be.

Further, the wire 43, the reel 44, and the motor 45 may be provided in a guide including the first concave portion 22 and the second concave portion 24 of the vehicle side guide 21 and the charger side guide 41. In this case, the hooking portion to which the wire 43 is hooked is provided on the guide including the insertion portion 42 of the vehicle side guide 21 and the charger side guide 41.

As shown in FIG. 8, the vehicle 10 may include an intermediate connector 91. The intermediate connector 91 includes a vehicle side guide 21 and a relay portion 92 integrated with the vehicle side guide 21. When the relay section 92 is inserted into the vehicle-side connector 12, the relay terminals 93 and 94 connected to the vehicle positive electrode terminal 13 and the vehicle negative electrode terminal 14, and the charging positive electrode terminal 34 and the charging negative electrode terminal 35 are respectively inserted. And terminal insertion portions 95 and 96. The intermediate connector 91 is used by inserting the relay portion 92 into the vehicle-side connector 12. By using the intermediate connector 91, the vehicle side guide 21 can be provided in the vehicle 10 that does not include the vehicle side guide 21. In this case, when the charger side guide 41 is fitted to the vehicle side guide 21, the vehicle side connector 12 and the charger side connector 33 are connected via the relay portion 92.

The vehicle-side connector 12 and the intermediate connector 91 themselves may be used as the vehicle-side guide by changing the shapes of the vehicle-side connector 12 and the intermediate connector 91. For example, the vehicle-side connector 12 or the intermediate connector 91 may be provided with a guide portion whose diameter increases toward the outside of the vehicle. In this case, the charger side connector 33 itself serves as a charger side guide.

A member other than the reel 44 and the motor 45 may be used as the winding unit, for example, a mainspring may be used. The mainspring is a member in which a spring material is spirally wound, and is wound, for example, around a shaft member. A wire 43 is connected to the end of the mainspring. When the wire 43 is pulled out, the mainspring spring extends so that the wire 43 is pulled out. Since the spiral spring has a force returning to the spiral shape, when the wire 43 is removed from the first hooking surface 27, the wire 43 is wound up.

The charger 30 may include a notification unit that can notify by light, sound, or the like when the charger-side connector 33 and the charger-side guide 41 return to predetermined positions.
At least one of the vehicle 10 and the charger 30 may be provided with a notification unit that can notify by light, sound, or the like when the claw portion 61 is hooked on the first hooking surface 27. As a result, the person who charges the battery can be notified that the wire 43 is locked.

A pin may be used as the hooking portion. In this case, the wire 43 can be hooked on the pin by providing an annular member that can be hooked on the pin at the tip of the wire 43 or by making the wire 43 itself ring-shaped. Since the pin is provided so as to be movable in the axial direction, the pin can be configured to project from the accommodating portion in which the pin is accommodated and to be accommodated in the accommodating portion. The lock state and the unlock state of the wire 43 can be switched by projecting the pin when hanging the wire 43 and retracting the pin when removing the wire 43.

The member that releases the locked state of the wire 43 may be a member other than the solenoid actuator 63. For example, a moving mechanism that can manually move the claw portion 61 may be provided. In this case, when the charger side connector 33 is detached from the vehicle side connector 12, the operator releases the locked state of the wire 43.

As the moving portion, a spring other than the spring 58 may be used. For example, the weight 57 may be slightly heavier than the weight that balances the charger-side connector 33 and the charger-side guide 41. In this case, when the wire 43 changes from the locked state to the unlocked state, the weight of the weight 57 causes the charger-side connector 33 and the charger-side guide 41 to return to the predetermined positions. An actuator such as a pneumatic cylinder or a hydraulic cylinder may be used as the moving unit.

The solenoid actuator 63 may be provided in the vehicle 10. In this case, energization and interruption of the solenoid actuator 63 are controlled by the ECU 11.
The support mechanism 50 is not limited to the configuration of the embodiment as long as it can support the charger-side connector 33 and the charger-side guide 41 in a movable state. In the embodiment, the charger side connector 33 and the charger side guide 41 are supported from above by the wire 43, but the charger side connector 33 and the charger side guide 41 may be supported from below.

The wire 43 may protrude from the charger side connector 33. That is, the wire 43 may protrude from a member that moves integrally with the charger-side guide 41 when wound on the reel 44.

The insertion of the wire 43 into the second recess 24 may be performed by a robot such as a drone. Since the robot conveys the wire 43 that is smaller and lighter than the charger-side connector 33, a robot having a low transportable mass or a robot having a low positioning accuracy is used as compared with the case where the charger-side connector 33 is conveyed. be able to. Therefore, the battery B can be charged using an inexpensive robot.

The reel 44 and the motor 45 may be provided at any position of the charger 30.
A plurality of wires 43 may be provided.
The charger side guide 41 and the charger side connector 33 may be covered with a flexible material.

A fence may be provided around the charger 30.
The spring 58 may be attached to the charger side guide 41.
