Abstract

PROBLEM TO BE SOLVED: To cause a charging connector disengagement prevention mechanism to mechanically cooperate with a lock pin in a projecting state to be in a charging connector disengagement prevention state in the course of inserting a charging connector into a charging port.SOLUTION: In the course of inserting a charging connector 2 into a charging port in an arrow direction in battery charging, a lock pin 11 provided projecting inside the charging port is moved through a solid line position inside a tip opening groove 2a of the charging connector 2 and ultimately to a two-dot chain line position. The lock pin 11 at this time rotates a check rotating member 12 by 90° in an arrow direction pushing a piece 12a intersecting the groove 2a. Such rotation of the member 12 causes the tip 13a of a spring plate 13 to engage with a check projection 12f on the adjacent side in the direction of rotation, and thereby disabling the rotation of the check rotating member 12 in the inverse direction from the rotation position. Such check of the rotating member 12 causes a piece 12b to intersect the groove 2a, and the piece 12b holds the lock pin 11 at the two-dot chain line position as it is, and thereby preventing disengagement of the charging connector 2 during battery charge by the cooperation between the piece 12b and the lock pin 11.

Description

  The present invention relates to an external charger connection structure for a vehicle that is used when charging an in-vehicle battery with electric power from an out-of-vehicle charger with the charging connector of the in-vehicle charger inserted into the in-vehicle charging port, and in particular, the charging connector is being charged. The present invention relates to a proposal for improving a charging connector removal preventing mechanism that prevents the charging port from being detached.

It is not preferable that the charging connector is detached from the charging port during charging because the charging power supply path is a strong electric system.
Therefore, it is necessary to prevent the charging connector from coming off from the charging port during charging, and as a charging connector removal preventing mechanism for that purpose, the one described in Patent Document 1, for example, has been conventionally known. .

  This proposed technology is provided with a lock pin that protrudes with a spring in a direction crossing the insertion / removal direction of the charging connector, and when the charging connector is inserted into the charging port during charging, the locking pin is locked by the urging of an electromagnetic solenoid. The pin is retracted from the protruding position against the spring, so that the charging connector can be inserted into the charging port.When charging the battery with the charging connector inserted, the lock pin is retracted by the spring due to the deactivation of the electromagnetic solenoid. Thus, the charging connector in the inserted state is prevented from coming off from the charging port.

However, in the above-described type of charging connector removal prevention mechanism, if the electromagnetic solenoid itself or a control system including its power supply fails, the electromagnetic solenoid cannot be energized, and the lock pin is resisted by the spring. And cannot be retracted from the protruding position.
In this case, the charging connector cannot be inserted into the charging port, the battery cannot be charged, and the vehicle cannot be driven when the battery storage state is low.

  According to the present invention, instead of obtaining the charging connector removal prevention function by moving the lock pin forward and backward, the charging connector side is provided with means for performing the charging connector removal prevention function mechanically in cooperation with the lock pin when the charging connector is inserted. It is an object of the present invention to provide a vehicle external charger connection structure that can solve the above-described problems.

The vehicle external charger connection structure of the present invention is designed to fulfill the function of preventing the charging connector from coming off by devising the following basic arrangements.
That is, first, the charging connector removal restriction member that allows the charging connector to pass through the charging connector removal restriction member so that the charging connector can be inserted into the charging port even by the protruding charging connector removal restriction member. A passage groove is formed to extend from the front end surface of the charging connector in the insertion direction of the charging connector.

Further, during the insertion process of the charging connector, the pushing piece at the position intersecting with the charging connector removal restriction member passage groove is pushed by the charging connector removal restriction member passing through the charging connector removal restriction member passage groove. A non-return rotating member that rotates is provided.
When the rotating member rotates, the charging connector retaining piece adjacent to the rear in the rotation direction crosses the charging connector removal restricting member passage groove so that the charging member in the projecting state is in the projecting state. The present invention is characterized in that it is configured to control the removal of the charging connector in cooperation with the connector removal limiting member.

According to the vehicle external charger connection structure of the present invention described above,
While the charging connector is inserted into the charging port, the protruding charging connector removal restricting member passes through the charging connector removing restriction member passage groove, so that the protruding charging connector removing restriction member also prevents the charging connector from being inserted. I can't.

When the charging connector is inserted, the charging connector removal restricting member passing through the charging connector removal restriction member passing groove receives the push piece of the non-return rotating member at a position intersecting with the charging connector removal restriction member passing groove. Push to rotate the check rotating member.
When the rotating member rotates, the charging connector retaining piece adjacent to the rear in the rotational direction crosses the charging connector detachment restricting member passage groove, so that the charging connector detachment restriction in the projecting state is restricted. The function to prevent the charging connector from coming off is exhibited in cooperation with the member.

  As described above, according to the present invention, when the charging connector is inserted, the charging connector removal preventing function is mechanically performed in cooperation with the charging connector removal limiting member, and the charging connector removal preventing mechanism is controlled. Since it is not necessary, the charging connector cannot be inserted due to the failure of the operation system, and the problem of the inability to charge due to the failure of the operation system can be avoided.

In this state, by operating the charging stand 1, the power of the charging stand 1 is sequentially directed to the battery 5 through the power cable 3, the charging connector 2, the charging port 7, and the charging cable 9, and charging to this is performed.
After the completion of charging, the above-described power supply is terminated by operating the charging stand 1, and then the charging connector 2 is pulled out from the charging port 7 and removed, and the opening / closing lid 8 is changed from the open position to the closed position in FIG.

<Charging connector removal prevention mechanism>
By the way, in the above external charger connection structure, when the charging connector 2 is inserted into the charging port 7 and the charging connector 2 is disconnected from the charging port 7 during battery charging, the charging power supply path is a strong power. Since it is a system, it is not preferable.

Therefore, it is necessary to prevent the charging connector 2 from being detached from the charging port 7 during charging. In this embodiment, the charging connector removal preventing mechanism for this purpose is shown in FIGS. A lock pin 11 provided in the charging connector 2 so that the charging connector 2 can be inserted into the charging port 7 even by the presence of the lock pin 11, and the lock pin passage groove 2a. 4 and 9 for preventing the charging connector 2 from detaching from the charging port 7 in cooperation with the lock pin 11 inside.
Therefore, the lock pin 11 corresponds to the charging connector removal limiting member in the present invention, and the lock pin passage groove 2a corresponds to the charging connector removal limiting member passage groove in the present invention.

  Note that the lock pin passage groove 2a is for allowing the lock pin 11 to pass during insertion of the charging connector 2 into the charging port 7 so that the charging connector 2 can be inserted. As shown in 2-5, the charging connector 2 is opened at the leading end surface in the insertion direction and extends from here to the charging connector removal direction to form the charging connector 2 at the leading end portion in the insertion direction.

As shown in FIG. 3, the lock pin 11 crosses the direction of insertion / removal of the charging connector 2 with respect to the charging port 7 (indicated by an arrow in FIG. 3) (as shown in FIG. Fix the charging port 7 so that it protrudes downward.
Further, the lock pin passage groove 2a provided in the charging connector 2 is extended so that the deepest portion thereof is substantially aligned with the lock pin 11 at the insertion completion position of the charging connector 2 shown in FIG.

In order to prevent the charging connector 2 from coming out of the charging port 7 by cooperating with the lock pin 11 at the deepest part of the lock pin passage groove 2a at the insertion completion position of the charging connector 2 shown in FIG. 4 to 9 will be described in detail below.
4 shows the entire charging connector 2, and a rotating member 12 is provided in the charging connector 2 as shown in FIGS.
The rotating member 12 is supported in the charging connector 2 so as to be rotatable around the central axis O1, and rotated so that the central axis O1 extends in parallel with the lock pin 11 near one side of the lock pin passage groove 2a. Arrange member 12.

As shown in FIG. 5, the rotating member 12 is configured as a cross-shaped rotating member having four pieces 12a, 12b, 12c, 12d arranged at equal intervals in the rotation direction when viewed in the direction of the rotation axis O1.
Further, the rotating member 12 is in a position where the four pieces 12a to 12d sequentially cross the lock pin passage groove 2a (in FIG. 5, the piece 12a crosses the passage groove 2a) in the direction of the arrow in FIG. A non-return rotating member having the following non-return mechanism is provided to prevent reverse rotation every 90 ° rotation.

This non-return mechanism comprises a rectangular block 12e concentrically fixed to the cross-shaped rotating member 12, and a spring plate 13.
The rectangular block 12e has check projections 12f at four corners, and the spring plate 13 is attached to the charging connector 2 with a screw 14 at the base end as shown in FIG.
The mounting position of the spring plate 13 is such that the tip 13a of the spring plate 13 engages with one of the check protrusions 12f as shown in FIGS. Is able to rotate in the direction of the arrow in FIG. 5, but obtains a non-returning function that makes it impossible to rotate in the opposite direction (the direction of the arrow in FIG. 8).

According to the above configuration, the function for preventing the charging connector 2 from coming off can be obtained as follows.
When charging, the charging connector 2 is inserted into the charging port 7 from the position shown in FIG. 3 (a) as shown in FIG. 3 (b).
In this process, even if the lock pin 11 remains in the protruding state, the lock pin passage groove 2a is provided at the tip of the charge connector 2, so that it can pass through the groove 2a. Its insertion is not hindered.
Charging is possible when the charging connector 2 is further inserted into the charging port 7 through the position shown in FIG. 3 (b) to the position shown in FIG. 3 (c). During this time, the lock pin 11 passes through the solid line position shown in FIG. Thus, the position is a two-dot chain line.

The lock pin 11 passing through the lock pin passage groove 2a in the process of inserting the charging connector 2 is a piece crossing the lock pin passage groove 2a during the period from the solid line position in FIG. 5 to the final two-dot chain line position. Press 12a.
At this time, the piece 12a serves as a pushing piece that is pushed by the lock pin 11 passing through the groove 2a and causes the rotation of the non-return rotating member 12.
The direction of the arrow in FIG. 5 is such that when the piece 12a is pushed by the lock pin 11 passing through the groove 2a, the non-return rotating member 12 is in the position of the piece 12a and the piece 12b is in the position of the piece 12a. Rotated 90 ° to.

With the rotation of the check rotating member 12, the tip 13a of the spring plate 13 comes into engagement with the check protrusion 12f adjacent to the rotation direction, and the check rotating member 12 cannot be rotated in the reverse direction from this rotation position. Eggplant.
The piece 12b crossed with the lock pin passage groove 2a due to the reverse rotation of the rotating member 12 keeps the lock pin 11 at the position of the two-dot chain line in FIG. 5 at this position, and the piece 12b and the lock pin 11 Can prevent the charging connector 2 from coming off during charging.
At this time, the piece 12b serves as a charge connector retaining piece that controls the removal of the charge connector 2.

After charging, it is necessary to remove the charging connector 2 in the inserted state shown in FIG. 3 (c) from the charging port 7. Non-return rotating member reverse rotation means for rotating the member 12 in reverse will be described in detail below.
This means is constituted by one release lever 15 (one manual operation member) shown in FIGS. 5, 6, and 9. This release lever 15 has a spring plate 13 with a tip 13a and a check projection 12f. The non-rotating member 12 is elastically deformed so as to be disengaged, and the piece (in FIG. 5, the piece 12a) that is opposite to the piece (the piece 12a in FIG. 5) that intersects the lock pin passage groove 2a. 12c) is rotated 90 ° in the direction opposite to the direction of the arrow in FIG. 5, and the adjacent piece (the piece 12d in FIG. 5) on the advancing side in the reverse direction is locked in the lock pin passage groove 2a. It is assumed that the pin 11 is driven from the two-dot chain line position to the solid line position.

For this reason, the release lever 15 includes a hook portion 15a that can be engaged with the spring plate 13 to elastically deform the spring plate 13 so that the tip portion 13a is disengaged from the check protrusion 12f, and a lock. Engage with the piece (piece 12c in FIG. 5) that is opposite to the piece that intersects the pin passage groove 2a (piece 12c in FIG. 5) and put the non-returning rotary member 12 in the direction opposite to the arrow direction in FIG. A hook portion 15b capable of rotating reversely by 90 ° is integrally provided.
The release lever 15 can be linearly displaced between the locked position shown in FIGS. 5, 6, and 9 and the unlocked position stroked in the unlocking direction indicated by an arrow in FIG. Attach to.

At the time of this attachment, the release lever 15 is normally supported by the spring means (not shown) in the locked position shown in FIGS. 5, 6 and 9, and the operation end 15c far from the hook portions 15a and 15b is as shown in FIG. It is assumed that the attachment is performed so as to be exposed to the outside of the charging connector 2.
In the normal state where the release lever 15 is elastically supported at the locked position shown in FIGS. 5, 6 and 9, the hook portions 15a and 15b are retracted from the spring plate 13 and the check rotating member 12, respectively. When the release lever 15 is pulled to the unlocking position by the same direction stroke by pulling in the unlocking direction indicated by the arrow in the figure, the hook portions 15a and 15b act on the spring plate 13 and the non-return rotating member 12 respectively to It shall function.

According to the above-described configuration, after charging, the prevention of removal of the charging connector 2 can be released as follows, and the charging connector 2 can be taken out from the charging port 7.
After charging, pull the operating end 15c of the release lever 15 exposed from the charging connector 2 as shown in Fig. 4 to the front, and move the release lever 15 from the normal position (lock position) in Figs. Stroke in the direction to the unlock position.

During the stroke of the release lever 15, on the other hand, the hook portion 15a elastically deforms the spring plate 13 so that the tip portion 13a is disengaged from the check protrusion 12f, and the check rotating member 12 rotates in the reverse direction. Possible state and none,
On the other hand, the hook portion 15b engages with a piece (the piece 12c in FIG. 5) that is directly opposite to the piece (the piece 12a in FIG. 5) intersecting with the lock pin passage groove 2a, and the non-return rotating member 12 is illustrated. Reverse 90 ° in the direction opposite to the arrow 5 direction.

Due to the 90 ° reverse rotation of the non-return rotating member 12, the opposite side advance piece (the piece 12d in FIG. 5) of the opposite side piece (the piece 12c in FIG. 5) with which the hook portion 15b is engaged is the lock pin passage groove. The lock pin 11 in 2a is pushed out from the two-dot chain line position in FIG. 5 to the solid line position, and the charging connector 2 is relatively pushed out from the charging port 7 to the removal prevention release position.
Thereafter, the charging station user can pull out the charging connector 2 from the charging port 7 by hand.

By the way, in order to prevent the charging connector 2 from coming off, the charging lever 2 must not be released even if the operating end 15c of the release lever 15 is accidentally pulled forward as long as charging is in progress.
Further, from the viewpoint of preventing theft of the vehicle during charging, the prevention of the removal of the charging connector 2 should not be released without permission by a person other than the charging stand user.
Therefore, in this embodiment, unless the charging stand user permits after the completion of charging, the prevention of the release of the charging connector 2 cannot be released, that is, the release lever 15 is moved to the normal position (lock position) shown in FIGS. Release / lever locking means is provided to prevent the stroke from the direction of the arrow (toward the unlocking position) as follows.

  The release lever lock means includes lock holes 15d and 15e drilled in the intermediate portion between the hook portions 15a and 15b of the release lever 15 and the operation end 15c as shown in FIGS. , 10 includes a solenoid lock 16 which is an electromagnetic lock means attached in the charging connector 2 and a key lock 17 which is a mechanical lock means.

The solenoid lock 16 has a lock pin 16a that enters the lock hole 15d and prohibits the stroke of the release lever 15 when the release lever 15 is in the normal position (lock position) of FIGS.
The lock pin 16a is normally elastically supported by a tension spring 16b at a retracted position indicated by a solid line in FIG. 10 (a) .For example, when the solenoid lock 16 is energized in response to the start of charging, the lock position indicated by a two-dot chain line in FIG. Then, it enters into the lock hole 15d and, for example, when the solenoid lock 16 is de-energized in response to the completion of charging, it is moved to the position indicated by the solid line by the spring 16b and retracted from the lock hole 15d.

The key lock 17 has a lock pin 17a that enters the lock hole 15e and prohibits the stroke of the release lever 15 when the release lever 15 is in the normal position (lock position) of FIGS. The lock pin 17a is usually elastically supported by a tension spring 17b at a retracted position indicated by a solid line in FIG. 10 (a).
As shown in detail in FIG. 11, the key lock 17 is provided so that the lock pin 17a is prevented from rotating by an axial protrusion 17c provided on the outer periphery thereof and is movable in the axial direction.
A plurality of numerical rings 17d are arranged concentrically with the lock pin 17a so as to be individually rotatable, adjacent to each other in the axial direction, and the axial protrusions 17c of the lock pin 17a are inserted into the inner circumference of the numerical ring 17d, respectively. A possible keyway 17e is formed.

  The key lock 17 is configured such that the numerical value of the lock ring 17d is adjusted so that each key groove 17e is in a rotational position aligned with the axial protrusion 17c in the axial direction as shown in FIG. ) From the locked position indicated by the two-dot chain line to the unlocked position indicated by the solid line in the figure, and the axial protrusion 17c at the locked position indicated by the two-dot chain line in FIG. 10 (a) of the lock pin 17a. Are not meshed with any of the key grooves 17e, and the axial protrusions 17c are meshed with all the key grooves 17e at the unlock position shown by the solid line in FIG. 10 (a) of the lock pin 17a.

Therefore, when any one of the numerical rings 17d is out of the above-described numerical alignment state while the lock pin 17a is in the locked position indicated by the two-dot chain line in FIG. Forbid the stroke of
The key lock 17 prevents the lock pin 17a from being displaced from the locked position indicated by the two-dot chain line in FIG. 10 (a) to the unlocked position indicated by the solid line in FIG.
As shown in FIG. 10 (a), the solenoid lock 16 and the key lock 17 are integrally coupled to each other by the connecting rod 18 at the rear ends of the lock pins 16a and 17a.

The operation of the release lever lock means having the above-described configuration will be described below.
When charging connector 2 is inserted into charging port 7 to start charging, solenoid lock 16 is energized in response to the start of charging.
Due to the urging of the solenoid lock 16, the lock pin 16a enters the lock hole 15d from the unlock position shown by the solid line in FIG. 10A to the lock position shown by the two-dot chain line.

In conjunction with this, the lock pin 17a of the key lock 17 also enters the lock hole 15e from the unlock position indicated by the solid line in FIG.
Therefore, the solenoid lock 16 and the key lock 17 can prevent the release lever 15 from moving to the charging connector removal prevention release position in cooperation with the lock pins 16a and 17a and the lock holes 15d and 15e. Even if the operation end 15c of the release lever 15 is accidentally pulled forward during charging, the prevention of the removal of the charging connector 2 is not released.

When the lock pin 17a of the key lock 17 advances from the unlock position to the lock position in conjunction with the lock pin 16a of the solenoid lock 16, the axial protrusion 17c of the lock pin 17a is connected to all the key grooves 17e. From the meshed state, the key groove 17e is not meshed as shown in FIG.
For this reason, all the numerical wheels 17d can be rotated individually, and the key lock 17 is unlocked from the lock position of the lock pin 17a by setting the numerical wheel 17d to a rotational position deviated from the above-described numerical value alignment state by this rotation. It is kept in a state that prohibits retreating to the position.

  Therefore, even if a person other than the charging station user tries to move the vehicle being charged, even if the lock pin 16a is moved backward from the locked position to the unlocked position due to the deactivation of the solenoid lock 16, this is linked. Thus, the lock pin 17a of the key lock 17 does not retract from the lock position to the unlock position, and the vehicle can be prevented from being stolen during charging.

When charging is completed, the solenoid lock 16 is de-energized in response to this, and the lock pin 16a is displaced from the lock position to the unlock position by the spring 16b, and tries to retreat from the lock hole 15d.
When the charging is completed, the charging stand user individually rotates the numerical wheels 17d to return to the rotation position corresponding to the above-described numerical value adjustment state, so that the key lock 17 moves backward from the lock position of the lock pin 17a to the unlock position. Is allowed.

Therefore, when the solenoid lock 16 corresponding to the completion of charging is deenergized, the lock pin 16a is displaced from the lock position to the unlock position by the spring 16b, retreats from the lock hole 15d, and interlocked with this, the key lock 17 The lock pin 17a is also displaced from the lock position to the unlock position, and retracts from the lock hole 15e.
Therefore, pull the operating end 15c of the release lever 15 exposed from the charging connector 2 as shown in Fig. 4 to the front, and move the release lever 15 from the normal position (lock position) of Figs. Stroke to unlock position.

During the stroke of the release lever 15, on the other hand, the hook portion 15a elastically deforms the spring plate 13 so that the tip portion 13a is disengaged from the check protrusion 12f, and the check rotating member 12 rotates in the reverse direction. Possible state and none,
On the other hand, the hook portion 15b engages with a piece (the piece 12c in FIG. 5) that is directly opposite to the piece (the piece 12a in FIG. 5) intersecting with the lock pin passage groove 2a, and the non-return rotating member 12 is illustrated. Reverse 90 ° in the direction opposite to the arrow 5 direction.

Due to the 90 ° reverse rotation of the non-return rotating member 12, the opposite side advance piece (the piece 12d in FIG. 5) of the opposite side piece (the piece 12c in FIG. 5) with which the hook portion 15b is engaged is the lock pin passage groove. The lock pin 11 in 2a is pushed out from the two-dot chain line position in FIG. 5 to the solid line position, and the charging connector 2 is relatively pushed out from the charging port 7 to the removal prevention release position.
Thereafter, the charging station user can pull out the charging connector 2 from the charging port 7 by hand.

<Operation / Effect of Example>
According to the vehicle external charger connection structure of the above-described embodiment,
During insertion of the charging connector 2 into the charging port 7, the protruding lock pin 11 can pass through the lock pin passage groove 2a provided in the charging connector 2, so that the charging connector 2 is also present due to the presence of the protruding locking pin 11. Insertion of is not hindered.

In the process of inserting the charging connector 2, as shown in FIG. 5, the non-return rotating member in which the lock pin 11 passing through the lock pin passage groove 2a from the solid line position to the two-dot chain line position intersects the lock pin passage groove 2a. The pushing member 12a of 12 is pushed to rotate the non-rotating rotating member 12 in the direction of the arrow in FIG. 5. At this time, the charging connector retaining piece 12b adjacent to the back of the non-rotating rotating member 12 in the rotation direction newly passes through the lock pin. The non-return rotating member 12 (charging connector retaining piece 12b) that is prevented from reverse rotation by the engagement between the spring plate 13 (tip portion 13a) and the non-return protrusion 12f by being in a position intersecting with the groove 2a. In order to prevent the charging connector 2 from coming off by cooperating with the lock pin 11 at the two-dot chain line position in the protruding state,
When the charging connector 2 is inserted, the function of preventing the detachment of the charging connector 2 is performed mechanically in cooperation with the lock pin 11, and the mechanism for preventing the detaching of the charging connector 2 does not need to be controlled. Thus, the charging connector cannot be inserted due to the failure, and the problem of the charging failure due to the failure of the operation system can be avoided.

After charging, when pulling out the charging connector 2 from the charging port 7 and removing it, pull the operating end 15c of the release lever 15 forward, and move the release lever 15 from the normal position (locked position) in FIGS. Stroke in the direction of the arrow to the unlock position.
During the stroke, the release lever 15 is non-returned by elastically deforming the spring plate 13 in the corresponding direction by the hook portion 15a so that the tip end portion 13a of the spring plate 13 is not engaged with the check protrusion 12f. The rotating member 12 is in a state in which it can be rotated in reverse,
On the other hand, the hook member 15b engages with a piece (the piece 12c in FIG. 5) that is directly opposite to the piece (the piece 12a in FIG. 5) that intersects the lock pin passage groove 2a, and the non-return rotating member 12 is illustrated. By rotating 90 ° in the direction opposite to the direction of the arrow 5 in the opposite direction (the piece 12c in FIG. 5) in the reverse rotation direction, the adjacent piece (the piece 12d in FIG. 5) adjoins the lock pin passage groove 2a. Since the lock pin 11 is driven out from the two-dot chain line position in FIG. 5 to the solid line position, the charging connector 2 can be pulled out from the charging port 7 by hand.

In this embodiment, the unlocking operation for releasing the release lever 15 from the locked position shown in FIGS. 5, 6 and 9 in the direction of the arrow is performed by using the solenoid lock 16 which is unlocked in response to the end of charging, and the charging stand. If the solenoid lock 16 and the key lock 17 are configured to be prohibited by the key lock 17 that can be unlocked by adjusting the numerical value of the numerical wheel 17d by the user, and the key lock 17 is in the unlockable state, Since they are configured to work together,
Unless the charging station user permits it after charging is complete, the release lever 15 cannot be released from the locking position shown in FIGS. Become.

  For this reason, even if the operating end 15c of the release lever 15 is accidentally pulled forward during charging, the prevention of removal of the charging connector 2 will not be released, and a person other than the charging stand user may be charging in the middle. Thus, even if the operation end 15c of the release lever 15 is pulled forward, the prevention of removal of the charging connector 2 is not released, and the vehicle can be prevented from being stolen during charging.

In this embodiment, the hook portions 15a and 16b are operated by a common release lever 15,
The spring plate 13 is elastically deformed in the corresponding direction by the hook portion 15a, and the manual operation to disengage the tip portion 13a of the spring plate 13 from the check protrusion 12f, and the check rotary member 12 by 90 ° by the hook portion 15b The manual operation of rotating the lock pin 11 from the deepest part of the lock pin passage groove 2a by rotating it in reverse can be generated by operating one common release lever 15, and by the solenoid lock 16 and the key lock 17. Lock control and unlock control of the hook portions 15a and 16b need only be performed on the common release lever 15, and operability and controllability can be improved.
