　上記従来技術のような電動車両では、走行中にバッテリが発熱した場合には、バッテリ保護の観点から走行時の出力を低下させる必要がある。一方、高速道路を走行する場合等は高速走行が連続するためバッテリが発熱しやすい。このような場合に出力低下を起こさないためには、バッテリを持続的に冷却する必要がある。 In an electric vehicle like the above-mentioned conventional technology, when the battery heats up during traveling, it is necessary to reduce the output during traveling from the viewpoint of battery protection. On the other hand, when traveling on a highway, the battery tends to generate heat because high-speed traveling continues. In such a case, it is necessary to continuously cool the battery in order to prevent the output from decreasing.

　モバイルバッテリユニット１２０は、バッテリケース１２００、バッテリ部１２０１、電極部１２０２、把持部１２０３、締結部１２０４、及び孔１２０６を含む。バッテリケース１２００は、モバイルバッテリユニット１２０の外形を画定する略直方体の筐体であり、例えば樹脂材料で形成される。バッテリ部１２０１は、バッテリケース１２００の内部に収容され、電動モータ１２１等を駆動するための電力を蓄積する。例えば、バッテリ部１２０１は、１又は複数のバッテリセルで構成される。電極部１２０２は、バッテリケース１２００底面に設けられ、バッテリ部１２０１の電力を取り出し可能な電気接続部材（バッテリ側電気接続部材）である。電極部１２０２は、１以上の電極ないし端子を含む。前述のワイヤハーネス９１（図１参照）の一端部は、この電極部１２０２に接続される。 The mobile battery unit 120 includes a battery case 1200, a battery part 1201, an electrode part 1202, a grip part 1203, a fastening part 1204, and a hole 1206. The battery case 1200 is a substantially rectangular parallelepiped casing that defines the outer shape of the mobile battery unit 120, and is made of, for example, a resin material. The battery unit 1201 is housed inside the battery case 1200 and stores electric power for driving the electric motor 121 and the like. For example, the battery unit 1201 includes one or a plurality of battery cells. The electrode part 1202 is an electric connection member (battery-side electric connection member) provided on the bottom surface of the battery case 1200 and capable of taking out the electric power of the battery part 1201. The electrode part 1202 includes one or more electrodes or terminals. One end of the above-mentioned wire harness 91 (see FIG. 1) is connected to this electrode portion 1202.

The user removes (carries) the mobile battery unit 120 from the vehicle body 100 by using the grip portion 1203, mounts the mobile battery unit 120 on the vehicle body 100, or replaces it with another mobile battery unit 120. be able to.
　孔１２０６は、電極部１２０２にワイヤハーネス９１ａ，９１ｂの電極部９１１ａ、９１１ｂ（図４参照。以下、特に区別しない場合は単に「電極部９１１」と表現する。）を接続する際に、電極部１２０２に対する電極部９１１ａ、９１１ｂの位置決めを行うためのもの位置決め用の孔である。後述のガイド部材９１２を孔１２０６に挿入することにより、バッテリケース１２００の底面に平行な方向についての位置決めを行うことができる。また、締結部１２０４は、ボルト等の締結部材によりバッテリ部１２０１をバッテリケース１２００の底面に固定する。 The hole 1206 is used for connecting the electrode portions 1202 to the electrode portions 911a and 911b of the wire harnesses 91a and 91b (see FIG. 4; hereinafter, simply referred to as “electrode portion 911” unless otherwise specified). This is a positioning hole for positioning the electrode portions 911a and 911b with respect to 1202. By inserting a guide member 912, which will be described later, into the hole 1206, it is possible to perform positioning in a direction parallel to the bottom surface of the battery case 1200. Further, the fastening portion 1204 fixes the battery portion 1201 to the bottom surface of the battery case 1200 with a fastening member such as a bolt.
　図４は、車両本体１００側に設けられた電極部９１１及びその周辺の構成示す概略図である。本実施形態の場合、支持部材９１４に電極支持部材９１５が、さらに電極支持部材９１５に電極部９１１及びガイド部材９１２が支持されている。 FIG. 4 is a schematic diagram showing the configuration of the electrode unit 911 provided on the vehicle body 100 side and its surroundings. In the case of the present embodiment, the electrode support member 915 is supported by the support member 914, and the electrode portion 911 and the guide member 912 are supported by the electrode support member 915.
　電極部９１１は、モバイルバッテリユニット１２０の電極部１２０２と接続可能な電動車両１側の電気接続部材（車両側電気接続部材）である。これらが接続されることにより、ワイヤハーネス９１を介してバッテリ部１２０１に蓄電された電力が電動モータ１２１及び制御装置１２２等に供給される。電極部９１１は、１以上の電極ないし端子を含み、本実施形態の場合、複数の端子ピン９１１１が車幅方向に並んで配列されている。また、本実施形態の場合、電極部９１１は後述の変位ユニット１８０により変位自在に設けられており、モバイルバッテリユニット１２０が車両本体１００に装着された状態において電極部９１１が変位することで電極部１２０２に接続される。 The electrode part 911 is an electric connection member (vehicle-side electric connection member) on the electric vehicle 1 side that can be connected to the electrode part 1202 of the mobile battery unit 120. By connecting these, the electric power stored in the battery unit 1201 is supplied to the electric motor 121, the control device 122, and the like via the wire harness 91. The electrode portion 911 includes one or more electrodes or terminals, and in the case of the present embodiment, a plurality of terminal pins 9111 are arranged side by side in the vehicle width direction. In addition, in the case of the present embodiment, the electrode unit 911 is displaceably provided by the displacement unit 180 described later, and the electrode unit 911 is displaced when the mobile battery unit 120 is mounted on the vehicle body 100, whereby the electrode unit 911 is displaced. It is connected to 1202.
　ガイド部材９１２は、電極部９１１を電極部１２０２に接続する際の位置決めをするための部材である。ガイド部材９１２が孔１２０６に挿入されることにより、電極部９１１を支持する支持部材９１４は、バッテリケース１２００の底面に対して平行な方向への移動が制限される。これにより、電極部１２０２に対する電極部９１１の上記方向への移動が制限されるので、電極部１２０２に対する電極部９１１の位置が合わせられる。 The guide member 912 is a member for positioning when connecting the electrode portion 911 to the electrode portion 1202. By inserting the guide member 912 into the hole 1206, the support member 914 that supports the electrode portion 911 is restricted from moving in a direction parallel to the bottom surface of the battery case 1200. As a result, the movement of the electrode portion 911 with respect to the electrode portion 1202 in the above-described direction is restricted, so that the position of the electrode portion 911 with respect to the electrode portion 1202 is aligned.
　図５は、放熱部材１３０の構成を示す斜視図である。放熱部材１３０は、モバイルバッテリユニット１２０の熱を放熱するための部材であり、例えばアルミニウム、鉄、銅のような伝熱性能の高い金属材料により形成される。本実施形態の場合、放熱部材１３０は、板形状部１３０１と、板形状部１３０１から延びる複数の放熱フィン１３０２とを含む。なお、複数の放熱フィン１３０２については、それぞれ同様の構成を有しているため図面を見やすくする関係から一部の符号を省略している（図６ないし図９についても同様）。 FIG. 5 is a perspective view showing the structure of the heat dissipation member 130. The heat radiating member 130 is a member for radiating the heat of the mobile battery unit 120, and is made of, for example, a metal material having high heat transfer performance such as aluminum, iron, or copper. In the case of the present embodiment, the heat dissipation member 130 includes a plate-shaped portion 1301 and a plurality of heat dissipation fins 1302 extending from the plate-shaped portion 1301. It should be noted that some of the plurality of heat radiation fins 1302 have the same configuration, so some of the reference numerals are omitted for the sake of making the drawings easier to see (the same applies to FIGS. 6 to 9).
　板形状部１３０１は、放熱フィン１３０２が設けられている面と対向する面においてモバイルバッテリユニット１２０に当接し、その当接部分からモバイルバッテリユニット１２０の熱を吸収する。なお、板形状部１３０１の形状は適宜設計可能である。 The plate-shaped portion 1301 abuts the mobile battery unit 120 on the surface opposite to the surface provided with the heat dissipation fins 1302, and absorbs the heat of the mobile battery unit 120 from the abutting portion. The shape of the plate-shaped portion 1301 can be appropriately designed.
　また、複数の放熱フィン１３０２は、モバイルバッテリユニット１２０から吸収した熱を放熱するための部材である。なお、放熱フィン１３０２の形状としては、周知の構成を採用可能である。例えば、蛇腹状又は剣山状の放熱フィンを用いてもよい。 The plurality of heat radiation fins 1302 are members for radiating the heat absorbed from the mobile battery unit 120. As the shape of the radiation fin 1302, a known configuration can be adopted. For example, a bellows-shaped or sword-shaped radiating fin may be used.
　また、本実施形態では、放熱部材１３０の板形状部１３０１は、傾斜部１３０３、回動軸１３０５及び平面部１３０６をさらに含む。これらは、放熱部材１３０を変位させるための構成である。後述の変位ユニット１８０により、放熱部材１３０が回動軸１３０５を回動中心として回動することにより、放熱部材１３０が変位自在に設けられる。なお、その他の構成については、＜変位ユニットの構成及び作動＞の項目において変位ユニット１８０の作動と併せて説明する。 Further, in the present embodiment, the plate-shaped portion 1301 of the heat dissipation member 130 further includes the inclined portion 1303, the rotating shaft 1305, and the flat surface portion 1306. These are configurations for displacing the heat dissipation member 130. By the displacement unit 180 described later, the heat dissipation member 130 rotates about the rotation shaft 1305 as a rotation center, so that the heat dissipation member 130 is displaceably provided. Note that other configurations will be described together with the operation of the displacement unit 180 in the section <Configuration and operation of displacement unit>.
　なお、板形状部１３０１と複数の放熱フィン１３０２とは一体成型されてもよいし、それぞれ別の部材であってもよい。それぞれ別の部材である場合は、溶接、嵌合、締結その他の方法で板形状部１３０１と複数の放熱フィン１３０２とが互いに固定されてもよい。 The plate-shaped portion 1301 and the plurality of heat radiation fins 1302 may be integrally molded, or may be separate members. When they are separate members, the plate-shaped portion 1301 and the plurality of heat radiation fins 1302 may be fixed to each other by welding, fitting, fastening, or any other method.
　図６はモバイルバッテリユニット１２０が車両本体１００に装着された場合のモバイルバッテリユニット１２０およびその周辺の構成を示す概略図であって、図１のＩ－Ｉ線断面図である。本実施形態では、放熱部材１３０及び電極部９１１は変位可能に構成されているが、図６は、放熱部材１３０がモバイルバッテリユニット１２０に当接した作動位置にあり、かつ、電極部９１１が電極部１２０２に接続した接続位置にある状態を示している。なお、図６は概略図であり、見易さを考慮して一部構成を省略している。 FIG. 6 is a schematic diagram showing the configuration of the mobile battery unit 120 and its surroundings when the mobile battery unit 120 is attached to the vehicle body 100, and is a cross-sectional view taken along the line II of FIG. 1. In the present embodiment, the heat dissipation member 130 and the electrode portion 911 are configured to be displaceable, but in FIG. 6, the heat dissipation member 130 is in the operating position where it abuts the mobile battery unit 120, and the electrode portion 911 is the electrode. It shows a state in which it is in a connection position where it is connected to the portion 1202. It should be noted that FIG. 6 is a schematic diagram, and part of the configuration is omitted for the sake of easy viewing.
　本実施形態では、モバイルバッテリユニット１２０は箱状の収納部１２５内において車両本体１００に装着される。収納部１２５には、その上面にモバイルバッテリユニット１２０を着脱するため上面開口１２５１が設けられている。また、収納部１２５には、その底面に電極部９１１との干渉を避けるための底面開口１２５２が設けられ、その側面に放熱部材１３０との干渉を避けるための側面開口１２５３が設けられている。側面開口１２５３により、放熱部材１３０は、作動位置においてその少なくとも一部が収納部１２５の外部に配置されている。 In the present embodiment, the mobile battery unit 120 is attached to the vehicle body 100 inside the box-shaped storage portion 125. An upper surface opening 1251 is provided on the upper surface of the storage portion 125 for attaching and detaching the mobile battery unit 120. Further, the housing portion 125 has a bottom surface opening 1252 on its bottom surface for avoiding interference with the electrode portion 911, and a side surface opening 1253 for avoiding interference with the heat dissipation member 130 on its side surface. Due to the side surface opening 1253, at least a part of the heat dissipation member 130 is disposed outside the storage portion 125 in the operating position.
　また、収納部１２５の車幅方向の側面の両外側を、ダクト１１５によって形成された導入通路１１５２が通過している。このような構成により、放熱部材１３０は、作動位置において少なくとも一部が導入通路１１５２上に配置されている。本実施形態では、放熱部材の放熱フィン１３０２は、その全体が導入通路１１５２上に配置されている。これにより、より効果的にモバイルバッテリユニット１２０を冷却することができる。 In addition, the introduction passage 1152 formed by the duct 115 passes on both outsides of the side surface of the storage portion 125 in the vehicle width direction. With such a configuration, at least a part of the heat dissipation member 130 is arranged on the introduction passage 1152 in the operating position. In the present embodiment, the radiating fins 1302 of the heat radiating member are entirely arranged on the introduction passage 1152. Thereby, the mobile battery unit 120 can be cooled more effectively.
　なお、本実施形態の場合、モバイルバッテリユニット１２０が箱状の収納部１２５に収納された状態で装着されている。しかし、モバイルバッテリユニット１２０を車両本体１００に装着する態様はこれに限られず、車両本体１００がモバイルバッテリユニット１２０を支持可能な構成を有していればよい。 Note that, in the case of the present embodiment, the mobile battery unit 120 is mounted in a state of being housed in the box-shaped housing portion 125. However, the mode in which the mobile battery unit 120 is attached to the vehicle body 100 is not limited to this, and the vehicle body 100 may have a configuration capable of supporting the mobile battery unit 120.
　また、本実施形態では、放熱部材１３０が車両１の車幅方向からモバイルバッテリユニット１２０を挟むように当接している。これにより、車両の前方から後方へと流れる走行風の導入通路１１５２上に放熱部材１３０を容易に配置することができる。さらに、本実施形態の場合、モバイルバッテリユニット１２０が前後方向に並んで２つ配置されている。したがって、これらをより近接して配置することができる。しかしながら、放熱部材１３０が車両１の前後方向からモバイルバッテリユニット１２０を挟むように当接する構成も採用可能である。これにより、車幅方向にコンパクトに車両本体１００を構成することができる。また、本実施形態では１つのモバイルバッテリユニット１２０に対して２つの放熱部材１３０が設けられているが、１つのモバイルバッテリユニット１２０に対して１つ又は３つ以上の放熱部材１３０を設けてもよい。 Further, in the present embodiment, the heat dissipation member 130 is in contact with the vehicle 1 in the vehicle width direction so as to sandwich the mobile battery unit 120. Thereby, the heat dissipation member 130 can be easily arranged on the introduction passage 1152 for the traveling wind flowing from the front to the rear of the vehicle. Further, in the case of the present embodiment, two mobile battery units 120 are arranged side by side in the front-rear direction. Therefore, they can be arranged closer to each other. However, it is also possible to adopt a configuration in which the heat dissipation member 130 abuts the mobile battery unit 120 from the front-back direction of the vehicle 1 so as to sandwich the mobile battery unit 120. As a result, the vehicle body 100 can be compactly configured in the vehicle width direction. Further, in the present embodiment, two heat dissipation members 130 are provided for one mobile battery unit 120, but one or three or more heat dissipation members 130 may be provided for one mobile battery unit 120. Good.
　＜変位ユニットの構成及び作動＞
　図７Ａないし図７Ｃ、図８Ａないし図８Ｃ及び図９Ａないし図９Ｃは変位ユニット１８０の作動を示す概略図である。図７Ａ，図８Ａ，図９Ａは車両前方からみた図、図７Ｂ，図８Ｂ，図９Ｂは車両右側面からみた図、図７Ｃ，図８Ｃ，図９Ｃは上方からみた図である。また、図７Ａないし図７Ｃは放熱部材１３０が退避位置かつ電極部９１１が退避位置にある場合の図、図８Ａないし図８Ｃは放熱部材１３０が作動位置、かつ、電極部９１１が接続位置と退避位置との間の位置にある場合の図である。さらに、図９Ａないし図９Ｃは放熱部材１３０が作動位置かつ電極部９１１が接続位置にある場合の図である。なお、これらの図では、見易さを考慮して収納部１２５及びその他の構成を一部省略している。 <Structure and operation of displacement unit>
7A to 7C, 8A to 8C, and 9A to 9C are schematic views showing the operation of the displacement unit 180. 7A, 8A and 9A are views seen from the front of the vehicle, FIGS. 7B, 8B and 9B are views seen from the right side of the vehicle, and FIGS. 7C, 8C and 9C are views seen from above. 7A to 7C are diagrams when the heat dissipation member 130 is at the retracted position and the electrode portion 911 is at the retracted position, and FIGS. 8A to 8C are where the heat dissipation member 130 is at the operating position and the electrode portion 911 is retracted to the retracted position. It is a figure in the case of being in a position between positions. Further, FIGS. 9A to 9C are views when the heat dissipation member 130 is in the operating position and the electrode portion 911 is in the connection position. Note that in these drawings, the storage portion 125 and other components are partially omitted for the sake of easy viewing.
　変位ユニット１８０は、放熱部材１３０を作動位置と退避位置との間で変位させるためのものであり、レバー１８０１と、アーム１８０２と、ガイド部材１８０３とを含む。変位ユニット１８０により放熱部材１３０を変位させることにより、放熱部材１３０をモバイルバッテリユニット１２０から離間させた状態でモバイルバッテリユニット１２０の着脱を行うことができる。変位ユニット１８０は、例えば車両本体１００の車体フレームや収納部１２５に、レバー１８０１が回動可能な状態で支持されている。また、本実施形態では、変位ユニット１８０が電極部９１１を接続位置と退避位置との間で変位させる構成も有している。このため、変位ユニット１８０は、放熱部材１３０と電極部９１１とを連動して変位させることができる。 The displacement unit 180 is for displacing the heat dissipation member 130 between the operating position and the retracted position, and includes a lever 1801, an arm 1802, and a guide member 1803. By displacing the heat dissipation member 130 with the displacement unit 180, the mobile battery unit 120 can be attached and detached in a state where the heat dissipation member 130 is separated from the mobile battery unit 120. The displacement unit 180 is supported by, for example, the vehicle body frame of the vehicle body 100 or the storage portion 125, with the lever 1801 being rotatable. Further, in the present embodiment, the displacement unit 180 also has a configuration for displacing the electrode portion 911 between the connection position and the retracted position. Therefore, the displacement unit 180 can displace the heat dissipation member 130 and the electrode portion 911 in association with each other.
　レバー１８０１は、ユーザが把持して回動操作するための把持部１８０１ａと、把持部１８０１ａの両端に接続する回動部１８０１ｂと、回動部１８０１ｂに含まれ放熱部材１３０を変位させる変位部１８０１ｃとを含む。把持部１８０１ａは、モバイルバッテリユニット１２０が車両本体１００に装着された状態で、モバイルバッテリユニット１２０の上方で車幅方向に延びて配置されている。また、把持部１８０１ａの車幅方向の両端に回動部１８０１ｂがそれぞれ接続している。回動部１８０１ｂは、回動軸１８０１ｄに回動可能に支持されている。回動軸１８０１ｄは、例えば収納部１２５に支持される。回動部１８０１ｂに含まれる変位部１８０１ｃは、回動部１８０１ｂの回動に伴って放熱部材１３０の板形状部１３０１を車幅方向内側、すなわち、モバイルバッテリユニット１２０側に押すことで放熱部材１３０を変位させる。これにより、放熱部材１３０はモバイルバッテリユニット１２０に当接する。 The lever 1801 includes a grip portion 1801a for a user to grip and rotate, a rotating portion 1801b connected to both ends of the grip portion 1801a, and a displacement portion 1801c included in the rotating portion 1801b for displacing the heat dissipation member 130. Including and The grip portion 1801a is arranged above the mobile battery unit 120 and extends in the vehicle width direction when the mobile battery unit 120 is mounted on the vehicle body 100. Further, the rotating portions 1801b are connected to both ends of the grip portion 1801a in the vehicle width direction. The rotating portion 1801b is rotatably supported by the rotating shaft 1801d. The rotating shaft 1801d is supported by, for example, the storage unit 125. The displacement portion 1801c included in the rotating portion 1801b pushes the plate-shaped portion 1301 of the heat dissipating member 130 inward in the vehicle width direction, that is, the mobile battery unit 120 side with the rotation of the rotating portion 1801b. To displace. As a result, the heat dissipation member 130 contacts the mobile battery unit 120.
　アーム１８０２は、その一端において回動軸１８０１ｅを介してレバー１８０１と接続している。また、アーム１８０２は、上記一端と異なる端部において回動軸１８０２ａを介して支持部材９１４と接続している。これにより、回動部１８０１ｂが回動すると、アーム１８０２が上方に引き上げられ、それに伴い支持部材９１４及びそれに支持された電極部９１１が上方に変位する。すなわち、レバー操作により、電極部９１１が上方に変位する。 The arm 1802 is connected to the lever 1801 at one end thereof via a rotating shaft 1801e. Further, the arm 1802 is connected to the support member 914 via a rotation shaft 1802a at an end portion different from the one end. As a result, when the rotating portion 1801b rotates, the arm 1802 is pulled upward, and accordingly, the supporting member 914 and the electrode portion 911 supported by the supporting member 914 are displaced upward. That is, the electrode portion 911 is displaced upward by the lever operation.
　また、ガイド部材１８０３は、回動部１８０２ａの移動を規制する部材である。ガイド部材１８０３は、モバイルバッテリユニット１２０の底面に対して垂直な方向に延びるガイド溝１８０３ａを有している。回動部１８０２ａがガイド溝１８０３ａに沿って変位することで、電極部９１１がモバイルバッテリユニット１２０の底面に対して垂直な方向に変位する。これにより、電極部１２０２に対して電極部９１１を接続しやすくなる。 The guide member 1803 is a member that restricts the movement of the rotating portion 1802a. The guide member 1803 has a guide groove 1803a extending in a direction perpendicular to the bottom surface of the mobile battery unit 120. When the rotating portion 1802a is displaced along the guide groove 1803a, the electrode portion 911 is displaced in a direction perpendicular to the bottom surface of the mobile battery unit 120. This facilitates connection of the electrode portion 911 to the electrode portion 1202.
　本実施形態の場合、支持部材９１４は、支持部材９１４はフローティング機構１８４を介して支持されている。フローティング機構１８４は、支持部材９１４の位置をモバイルバッテリユニット１２０の底面に平行な方向に調整可能に支持されている。例えば、フローティング機構１８４は、バネ等の弾性部材の弾性力により、支持部材９１４に外力が働いた際にバッテリケース１２００の底面に平行な方向への移動を許容しながら支持部材９１４を支持している。これにより、モバイルバッテリユニット１２０に対する支持部材９１４の位置の微調整が可能となる。例えば、孔１２０６に対するガイド部材９１２の位置が若干量ずれている場合、ガイド部材９１２は孔１２０６の位置に合わせて移動してから挿入される。これにより、その後接続される端子ピン９１１１が正確な位置に合わされる。 In the case of this embodiment, the support member 914 is supported via the floating mechanism 184. The floating mechanism 184 is supported so that the position of the support member 914 can be adjusted in a direction parallel to the bottom surface of the mobile battery unit 120. For example, the floating mechanism 184 supports the support member 914 while allowing the movement in a direction parallel to the bottom surface of the battery case 1200 when an external force acts on the support member 914 by the elastic force of an elastic member such as a spring. There is. This allows fine adjustment of the position of the support member 914 with respect to the mobile battery unit 120. For example, when the position of the guide member 912 is slightly displaced from the hole 1206, the guide member 912 is moved according to the position of the hole 1206 and then inserted. As a result, the terminal pin 9111 to be connected thereafter is aligned with the correct position.
　図７Ａないし図７Ｃで示す放熱部材１３０が退避位置かつ電極部９１１が退避位置の状態からレバー１８０１を回動させると、図８Ａないし図８Ｃで示す放熱部材１３０が作動位置、かつ、電極部９１１が接続位置と退避位置との間の位置にある状態に推移する。変位部１８０１ｃは、回動部１８０１の回動に伴って放熱部材１３０の傾斜部１３０３を押すことにより、放熱部材１３０を退避位置から作動位置に向かって変位させる。そして、さらに回動部１８０１が回動して変位部１８０１ｃが傾斜部１３０３と連続する平面部１３０６まで到達すると、放熱部材１３０は作動位置に到達してモバイルバッテリユニット１２０に当接する。なお、このとき、電極部９１１も退避位置から接続位置に向かって変位しているが、図８Ａないし図８Ｃの時点では接続位置には到達せず両位置の間に位置している。また、図８Ａないし図８Ｃで示す状態においては、ガイド部材９１２も孔１２０６に対して挿入されていない。 When the lever 1801 is rotated from the state where the heat dissipation member 130 shown in FIGS. 7A to 7C is in the retracted position and the electrode portion 911 is in the retracted position, the heat dissipation member 130 shown in FIGS. 8A to 8C is in the operating position and the electrode portion 911. Shifts to a state between the connection position and the retracted position. The displacement part 1801c displaces the heat dissipation member 130 from the retracted position toward the operating position by pushing the inclined part 1303 of the heat dissipation member 130 as the rotating part 1801 rotates. Then, when the rotating portion 1801 further rotates and the displacement portion 1801c reaches the flat surface portion 1306 which is continuous with the inclined portion 1303, the heat dissipation member 130 reaches the operating position and contacts the mobile battery unit 120. At this time, the electrode part 911 is also displaced from the retracted position toward the connection position, but at the time point of FIGS. 8A to 8C, it does not reach the connection position and is located between both positions. Further, in the state shown in FIGS. 8A to 8C, the guide member 912 is not inserted into the hole 1206 either.
　また、図８Ａないし図８Ｃで示す状態からレバー１８０１をさらに回動させると、図９Ａないし図９Ｃで示す放熱部材１３０が作動位置かつ電極部９１１が接続位置の状態に推移する。変位部１８０１ｃは、図８Ａないし図８Ｃの状態からさらにレバー１８０１が回動しても平面部１３０６を押し続けるので、放熱部材１３０の位置は作動位置で維持される。一方、回動部１８０１の回動に伴って放熱部材１３０の傾斜部１３０３を押すことにより、放熱部材１３０が作動位置に向かって変位する。そして、ガイド部材９１２が孔１２０６に挿入されることにより電極部１２０２に対する電極部９１１の位置決めがなされた後に、電極部９１１は接続位置に到達して電極部１２０２と接続する。 Further, when the lever 1801 is further rotated from the state shown in FIGS. 8A to 8C, the heat dissipation member 130 shown in FIGS. 9A to 9C moves to the operating position and the electrode portion 911 to the connecting position. The displacement portion 1801c continues to push the flat portion 1306 even when the lever 1801 further rotates from the state of FIGS. 8A to 8C, and thus the position of the heat dissipation member 130 is maintained at the operating position. On the other hand, by pushing the inclined portion 1303 of the heat radiating member 130 in accordance with the rotation of the rotating portion 1801, the heat radiating member 130 is displaced toward the operating position. After the guide member 912 is inserted into the hole 1206 to position the electrode portion 911 with respect to the electrode portion 1202, the electrode portion 911 reaches the connection position and connects with the electrode portion 1202.
　上記のように、本実施形態では、変位ユニット１８０をユーザが操作すると、放熱部材１３０及び電極部９１１がそれぞれの退避位置から変位する。そして、まず放熱部材１３０が作動位置に到達し、その後、放熱部材１３０が作動位置にある状態で電極部９１１が接続位置に到達する。すなわち、放熱部材１３０がモバイルバッテリユニット１２０に当接された状態で電極部９１１が電極部１２０２に接続する。したがって、モバイルバッテリユニット１２０が２枚の放熱部材１３０に保持されることによりその位置が固定された状態で電極部９１１を電極部１２０２に接続できるので、より正確に電極部９１１の接続を行うことができる。特に、本実施形態では、放熱部材１３０がモバイルバッテリユニット１２０に当接され、モバイルバッテリユニット１２０の位置が固定されてからガイド部材９１２が孔１２０６に挿入されるので、より精度よく位置決めを行うことができる。 As described above, in the present embodiment, when the displacement unit 180 is operated by the user, the heat dissipation member 130 and the electrode portion 911 are displaced from their retracted positions. Then, the heat dissipation member 130 first reaches the operating position, and then the electrode portion 911 reaches the connection position with the heat dissipation member 130 in the operating position. That is, the electrode portion 911 is connected to the electrode portion 1202 in a state where the heat dissipation member 130 is in contact with the mobile battery unit 120. Therefore, since the mobile battery unit 120 is held by the two heat dissipation members 130, the electrode part 911 can be connected to the electrode part 1202 in a state where the position is fixed, so that the electrode part 911 can be connected more accurately. You can Particularly, in the present embodiment, since the heat dissipation member 130 is brought into contact with the mobile battery unit 120 and the position of the mobile battery unit 120 is fixed, the guide member 912 is inserted into the hole 1206, so that the positioning can be performed more accurately. You can
　また、本実施形態の場合、モバイルバッテリユニット１２０を冷却するための放熱部材１３０等の構成が車両本体１００側に設けられている。したがって、持ち運びする必要のあるモバイルバッテリユニット１２０側に冷却するための構成を設ける必要がないので、モバイルバッテリユニット１２０側の重量の増加を抑制しつつモバイルバッテリユニット１２０を冷却することができる。さらに、モバイルバッテリユニット１２０側に冷却するための構成を設ける必要がないので、その分バッテリ容量を大きくすることができる。 Further, in the case of the present embodiment, a structure such as a heat dissipation member 130 for cooling the mobile battery unit 120 is provided on the vehicle body 100 side. Therefore, it is not necessary to provide a structure for cooling on the side of the mobile battery unit 120 that needs to be carried, so that it is possible to cool the mobile battery unit 120 while suppressing an increase in weight on the side of the mobile battery unit 120. Further, since it is not necessary to provide a structure for cooling the mobile battery unit 120 side, the battery capacity can be increased accordingly.
　本実施形態では、変位ユニット１８０は、放熱部材１３０と電極部９１１とを連動して変位させている。しかしながら、上記構成は例示であり他の構成も採用可能である。例えば、放熱部材１３０及び電極部９１１に対してそれぞれを独立に変位可能な構成を設けてもよい。また、本実施形態では機械的な構成で放熱部材１３０及び電極部９１１を変位させているが、電動又は油圧アクチュエータ等により変位させてもよいし、機械的な構成とこれらを組み合わせてもよい。例えば、電極部９１１を変位ユニット１８０により機械的に変位させ、放熱部材１３０を油圧アクチュエータで変位させてもよい。このとき、変位ユニット１８０のレバー１８０１回動を契機に油圧アクチュエータを作動せることで電極部９１１の変位と放熱部材１３０の変位とを連動させてもよい。 In this embodiment, the displacement unit 180 displaces the heat dissipation member 130 and the electrode portion 911 in conjunction with each other. However, the above configuration is an example, and other configurations can be adopted. For example, a configuration may be provided in which the heat dissipating member 130 and the electrode portion 911 can be independently displaced. Further, in the present embodiment, the heat dissipation member 130 and the electrode portion 911 are displaced by a mechanical structure, but they may be displaced by an electric or hydraulic actuator or the like, or a mechanical structure and a combination thereof may be used. For example, the electrode unit 911 may be mechanically displaced by the displacement unit 180, and the heat dissipation member 130 may be displaced by a hydraulic actuator. At this time, the displacement of the electrode unit 911 and the displacement of the heat dissipation member 130 may be interlocked by operating the hydraulic actuator triggered by the rotation of the lever 1801 of the displacement unit 180.
