- the part below the axis line 01 is an area where the swing arm 71 escapes when shifting from the restricted state by the lock mechanism to the unrestricted state. Therefore, an area below the axis 01 is defined as an escape area and an area above the axis 01 is defined as a passing area.
- the swing arm 71 is symmetrical in the escape area and the passage area, there are many areas located on the escape area side of the claw portion 23d. In this case, there are the following problems. That is, since the position of the charging port 4 is provided at a relatively low position of the vehicle, it is assumed that when another vehicle travels nearby, sherbet-like snow, muddy water, etc. is wound up and scattered into the charging port 4. Is done. Further, when charging is performed in a cryogenic environment, it is assumed that the scattered sherbet-like snow and muddy water are frozen, and a slab-like obstacle is formed using the arm member 71d of the swing arm 71 as a roof.
- the arm member 71d is largely scraped from the symmetrical virtual line to the vicinity of the claw portion 23d.

- the shape is symmetrical with the axis line 01 as the reference line. That is, when the swing arm 71 is rotated by the operation of the lock actuator 73, assuming that the swing arm 71 does not sufficiently rotate due to a failure or the like, the length of the outermost diameter portion 71f is secured more reliably. This is because the swing arm 71 can be positioned in the separation direction of 23d.

- the outermost diameter portion 71f of the swing arm 71 is exposed. If the gap between the cover member 9 and the outermost diameter portion 71f is large, it is possible to forcibly open the swing arm 71 by inserting a finger or the like into the gap. Therefore, the gap between the swing arm 71 and the cover member 9 is set narrow so as not to contact.
- the rotation direction length of the outermost diameter part 71f is set longer than the opening width (length in the rotation direction) of the opening 91.
- the distance between the inner peripheral surface of the cover member 9 and the locus of the outermost diameter portion 71 f when the swing arm 71 rotates is set to increase as the distance from the opening 91 increases. ing. That is, when the charging connector 2 is connected to the charging port 4 with dust or the like (gum, mud, lump of dust, etc.) attached to the claw portion 23d, the swing arm 71 rotates to It will work while scraping (sweeping) garbage.

- a predetermined gap a1 is provided between the upper surface of the swing arm 71 and the support extending portion 74b, and a predetermined gap b1 is also provided between the lower surface of the swing arm 71 and the claw portion 23d. Therefore, since the swing arm 71 does not come into contact with the support extending portion 74b and the claw portion 23d when the swing arm 71 rotates, the swing arm 71 can be operated smoothly.
- FIG. 10 is a schematic cross-sectional view showing the positional relationship between the engaging member and the swing arm when the engaging member of Example 1 is forcibly operated in the separating direction.
- the support extending portion 74b is provided, further deformation is suppressed by contact with the support extending portion 74b.
- even the resin swing arm 71 can ensure a sufficient strength against the compressive force. That is, the swing axis of the swing arm 71 has a rotation axis that is different from the insertion / removal direction of the charging connector 2 and that is different from the rotation axis direction of the engagement member 23.
- the rotation axis direction of the swing arm 71 and the rotation axis direction of the engaging member 23 are not in a parallel relationship, and the swing arm 71 is interposed and limited in the separating direction of the claw portion 23d, and The support extending portion 74b is provided. Therefore, even if an unreasonable force is input from the claw portion 23d, the swing arm 71 does not act in the turning direction, so that it is not necessary to make the swing arm 71 robust in the turning direction. Sufficient restricted state can be maintained without having to make the structure near the shaft robust.

- a predetermined dead zone is generated in both directions around the center. In other words, if the toggle spring 100 does not rotate to some extent from when it is in the spring center position, it is not possible to generate a rotational torque that overcomes the friction.
- the motor 731 operates the swing arm 71 to the near side that reaches the lock position or the unlock position.
- the range in which the motor torque is output is a range from the unlock position to the predetermined lock region (hereinafter referred to as a first region) for the region acting in the lock direction.
- the region acting in the unlocking direction is a range from the lock position to the predetermined unlocking region beyond the center (hereinafter referred to as a second region).
- a second region since there is a dead zone in the toggle spring 100, if the operation of the motor 731 is stopped within this dead zone, the swing arm 71 cannot move due to the toggle spring force. Therefore, when operating the motor 731, the motor 731 is always driven to exceed the dead zone of the toggle spring 100. In other words, the motor 731 is controlled so that the first region and the second region overlap.

Is positioned closer to the lock side than the center line of the claw, in other words, the outermost diameter portion 71f is nail when viewed from the separation direction in the “center position” on the unlock side rather than the “front side position”. It overlaps part 23d by more than half.
- a first region for applying torque electrically using the motor 731 and a region for applying torque mechanically using the toggle spring 100 are formed. To do. As a result, the entire operating range of the swing arm 71 is not operated by the motor. Therefore, the swing arm 71 avoids an excessive load acting on the motor and the like to improve durability and is attached to a predetermined position by the toggle spring 100. A predetermined position is stably maintained by applying a force.
- the swing arm 71 and the claw portion 23d are not engaged at all when reaching the region that operates only by the toggle spring 100, that is, when they do not overlap at all when viewed from the separated direction,
- the achievement of the locked state depends only on the elastic force of the toggle spring 100.
- the swing arm 71 may not be sufficiently operated with a small torque due to contamination (garbage, mud, etc.) or freezing in a cold region. In such a scene, it depends on only the elastic force of the toggle spring 100. There is a possibility that sufficient rotation cannot be obtained, and there is a concern about reliability with respect to the locking operation.

図1は実施例1の電動車両の充電ポート装置を備えた車両の充電時の様子を表す概略図である。車両3の前方であって、ボンネットフード31より更に前方側には、車両3のフロアに搭載された車載バッテリ6とケーブル43により電気的に接続された充電ポート4が設けられている。この充電ポート4は、タイヤホイルアーチ33の上端と略同じ高さであってサイドミラー34よりも低い位置に設けられ、非充電時は充電リッド32により閉塞されている。充電スタンド1には、電力供給用の充電用コネクタ2が設けられており、充電時には、充電リッド32を開き、充電用コネクタ2を充電ポート4に差し込んで接続することで、充電を実施する。尚、実施例1の車両では、急速充電器に接続する場合の急速充電ポートと、家庭用電気等で充電する場合の通常充電ポートとの両方を備えており、実施例1の場合は通常充電ポートを例に説明する。急速充電ポートを使用する場合、比較的短時間の接続であり、長時間放置するような場面は少ないからである。尚、急速充電ポート側にロック機構を備えてもよいことは言うまでもない。
充電ポート4の上方には、係合部材23の回動を制限するロック機構7が設けられている。ロック機構7は、爪部23dが凸部41aから離間する方向に位置することで離間を制限する状態(以下、ロック状態)を達成し、離間する方向に位置しないことで離間を制限しない状態(以下、アンロック状態)を達成するスイングアーム71と、このスイングアーム71を駆動するロックアクチュエータ73と、ロックアクチュエータ73及び充電ポート4の被挿入部材41を固定支持するブラケット74とを有する。
(1)使用者の操作により充電用コネクタ2の係合部と係合する凸部41a(被係合部)を有し、係合状態において外部電源からの電力が供給される充電ポート4と、爪部23d(係合部)と凸部41aとが係合状態にある時に、爪部23dが凸部41aと離間する解除操作を規制することで、係合状態の解除を制限するスイングアーム71(制限部材)と、通電駆動によりスイングアーム71を動作させることで、離間方向から見て爪部23dとオーバーラップして爪部23dの解除操作を規制するロック状態と、爪部23dとオーバーラップせずに解除操作を許容するアンロック状態とを達成するロック機構7(ロック状態制御手段)と、を有し、ロック機構7は、スイングアーム71をロック状態もしくはアンロック状態である所定位置まで移動させるときに、所定位置よりも手前側までモータ731により電気的にトルクを付与することで移動させる電気式駆動機構と、手前側から所定位置までをスイングアーム71と車体側との間に設けたトグルスプリング100(機械的にトルクを付与することで移動させる機械式駆動機構)とを有し、スイングアーム71の一部は、ロック状態へ移動させるときの手前側位置において離間方向から見て爪部23dとオーバーラップすることとした。
よって、スイングアーム71の作動範囲全域をモータにより動作させないため、スイングアーム71はモータ等に過剰な負荷が作用することを回避することができ、耐久性の向上を図ることができる。また、トグルスプリング100により移動させるため、所定位置に付勢力を作用させることができ、安定して所定位置を維持することができる。また、電気的にトルクを付与可能な位置でスイングアーム71と爪部23dとがオーバーラップするため、ロック動作に対する信頼性を確保できる。
よって、不感帯においてスイングアーム71の作動が確保できない場合であってもロック状態を確保できる。
よって、不感帯にあってはモータ731により電気的にトルクを付与させることができるため、スイングアーム71の作動を確保できる。また、不感帯以外ではスイングアーム71をトグルスプリング100のトルクによってロック位置もしくはアンロック位置に移動させることができる。
