The mounting unit 20 includes a pair of support members 30 and a protection member 40.
　それぞれの支持部材３０は、平面視において電気自動車１の前後方向に延在する角筒の棒状部材であり、例えば、アルミニウム、鉄、ニッケル、又はそれらのうちの少なくとも一つを含む合金等から構成されている。 Each support member 30 is a rectangular tube rod-like member extending in the front-rear direction of the electric vehicle 1 in plan view, and is made of, for example, aluminum, iron, nickel, or an alloy containing at least one of them. Has been.
　この支持部材３０は、第１の固定部３１と、第１の支持部３２と、第１の屈曲部３３と、を有している。この支持部材３０は、第１の固定部３１でボルト締結等によってフロアパネル２に固定されている。 The support member 30 includes a first fixing portion 31, a first support portion 32, and a first bent portion 33. The support member 30 is fixed to the floor panel 2 by bolt fastening or the like at the first fixing portion 31.
　一方、この支持部材３０の第１の支持部３２には、受電ユニット１０がボルト締結等によって固定されている。このように、本実施形態では、支持部材３０を介して受電ユニット１０をフロアパネル２に取り付けるので、電気自動車１の車高に依存することなく、支持部材３０の高さによって、受電コイル１１と給電コイル５１との間の距離を設定することができる。 On the other hand, the power receiving unit 10 is fixed to the first support portion 32 of the support member 30 by bolt fastening or the like. Thus, in this embodiment, since the power receiving unit 10 is attached to the floor panel 2 via the support member 30, the power receiving coil 11 and the power receiving coil 11 depend on the height of the support member 30 without depending on the vehicle height of the electric vehicle 1. The distance to the power feeding coil 51 can be set.
　しかも、本実施形態では、受電ユニット１０とフロアパネル２との間に一つの部材を介在させるだけであるので、簡単且つ低コストで送電効率の向上を図ることができる。また、既存の電気自動車に対しても、非接触充電用の受電ユニット１０を簡単に後付けすることもできる。 Moreover, in this embodiment, since only one member is interposed between the power receiving unit 10 and the floor panel 2, it is possible to improve power transmission efficiency easily and at low cost. Further, the power receiving unit 10 for non-contact charging can be easily retrofitted to an existing electric vehicle.
　この際、本実施形態では、特に図２に示すように、当該受電ユニット１０の背面１２（同図における上面）が第１の支持部３２の下面３２１と接触するように、受電ユニット１０が第１の支持部３２に取り付けられている。 At this time, in the present embodiment, as shown in FIG. 2 in particular, the power receiving unit 10 is connected to the lower surface 321 of the first support portion 32 so that the back surface 12 (the upper surface in FIG. 1 is attached to one support portion 32.
　このため、受電ユニット１０の受電面１３（受電ユニット１０において給電ユニット５０と対向することとなる面。図１Ｂ参照。）が下方に向かって常に露出しており、受電ユニット１０と給電ユニット５０との間に支持部材３０が介在することがない。そのため、本実施形態では、非接触充電時に受電コイル１１と給電コイル５１との間に形成される磁束が、支持部材３０によって妨げてられてしまうことがない。 For this reason, the power receiving surface 13 of the power receiving unit 10 (the surface that faces the power feeding unit 50 in the power receiving unit 10; see FIG. 1B) is always exposed downward, and the power receiving unit 10, the power feeding unit 50, The support member 30 is not interposed between the two. Therefore, in this embodiment, the magnetic flux formed between the power receiving coil 11 and the power feeding coil 51 at the time of non-contact charging is not hindered by the support member 30.
　また、特に図４に示すように、この第１の支持部３２は、電気自動車１の一対の後輪４の間に設けられているので、この第１の支持部３２に固定された受電ユニット１０の受電コイル１１も、後輪４の間に位置している。一般的に、後輪４のホイールは、アルミニウム等の透磁率の低く且つ導電率の高い材料から構成されている。本実施形態では、こうした後輪４のホイールに受電コイル１１が挟まれているので、非接触充電時に受電コイル１１と給電コイル５１との間に形成される磁束が側方に漏洩するのを抑制することができる。 In particular, as shown in FIG. 4, since the first support portion 32 is provided between the pair of rear wheels 4 of the electric vehicle 1, the power receiving unit fixed to the first support portion 32. Ten power receiving coils 11 are also located between the rear wheels 4. Generally, the wheel of the rear wheel 4 is made of a material having a low magnetic permeability and high conductivity such as aluminum. In the present embodiment, since the power receiving coil 11 is sandwiched between the wheels of the rear wheel 4, it is possible to prevent the magnetic flux formed between the power receiving coil 11 and the power feeding coil 51 from leaking to the side during non-contact charging. can do.
　また、支持部材３０が棒状の部材で構成されているので、受電ユニット１０の背面１２を露出させることができる。このため、受電ユニット１０を効率的に冷却することができる。 Further, since the support member 30 is composed of a rod-shaped member, the back surface 12 of the power receiving unit 10 can be exposed. For this reason, the power receiving unit 10 can be efficiently cooled.
　さらに、この第１の支持部３２の下面３２１にはノッチ３４が形成されている。このノッチ３４は、電気自動車１の車幅方向に平行に延在しており、特に図４に示すように、平面視において受電コイル１１の略中央に対応するように形成されている。 Further, a notch 34 is formed on the lower surface 321 of the first support portion 32. This notch 34 extends in parallel to the vehicle width direction of the electric vehicle 1 and is formed so as to correspond to the approximate center of the power receiving coil 11 in plan view, as shown in FIG.
　例えば、電気自動車１の後退時に取付ユニット２０に縁石等が接触した場合には、このノッチ３４を起点として、受電ユニット１０自体が折れ曲がるので、電気自動車１の他の部品（例えば、受電ユニット１０に接続されたハーネスやバッテリ等）の損傷を抑制することができる。 For example, when a curb or the like comes into contact with the mounting unit 20 when the electric vehicle 1 moves backward, the power receiving unit 10 itself bends with the notch 34 as a starting point. Therefore, other parts of the electric vehicle 1 (for example, the power receiving unit 10 Damage to the connected harness or battery) can be suppressed.
　この際、ノッチ３４を支持部材３０の下面３２１に形成しておくことで、受電ユニット１０をフロアパネル２側に折り曲げることができ、折れ曲がった受電ユニット１０が地面に接触するのを防止することができる。 At this time, by forming the notch 34 on the lower surface 321 of the support member 30, the power receiving unit 10 can be bent toward the floor panel 2, and the bent power receiving unit 10 can be prevented from contacting the ground. it can.
　また、支持部材３０を棒状部材で構成しているので、板状部材と比較して、受電ユニット１０と共に支持部材３０も折り曲げやすくなっている。 Further, since the support member 30 is composed of a rod-shaped member, the support member 30 is easily bent together with the power receiving unit 10 as compared with the plate-shaped member.
　また、受電コイル１１が放射状に配置されたフェライトを有している場合であっても、ノッチ３４を受電コイル１１の略中央に対応するように形成しているので、当該フェライトに邪魔されることなく受電コイル１１を折り曲げることが可能となっている。 Further, even when the power receiving coil 11 has a radially arranged ferrite, the notch 34 is formed so as to correspond to the substantially center of the power receiving coil 11, so that it is disturbed by the ferrite. Thus, the power receiving coil 11 can be bent.
　支持部材３０において、第１の固定部３１と第１の支持部３２とは第１の屈曲部３３を介して繋がっている。第１の固定部３１及び第１の支持部３２がフロアパネル２の平面方向に対してほぼ平行に延在しているのに対し、この第１の屈曲部３３は、フロアパネル２２の法線方向（すなわち鉛直方向）に延在しており、第１の固定部３１と第１の支持部３２との間に略階段状の段差を形成している。 In the support member 30, the first fixing portion 31 and the first support portion 32 are connected via a first bent portion 33. The first fixed portion 31 and the first support portion 32 extend substantially parallel to the plane direction of the floor panel 2, whereas the first bent portion 33 is a normal line of the floor panel 22. It extends in the direction (that is, the vertical direction), and a substantially stepped step is formed between the first fixed portion 31 and the first support portion 32.
　このため、受電ユニット１０は支持部材３０によってフロアパネル２から離れた状態で保持されており、受電ユニット１０の背面１２とフロアパネル２の下面との間には空間３が形成されている。 For this reason, the power reception unit 10 is held away from the floor panel 2 by the support member 30, and a space 3 is formed between the back surface 12 of the power reception unit 10 and the lower surface of the floor panel 2.
　本実施形態では、受電ユニット１０とフロアパネル２との間に形成されたこの空間３に風が通ることで、受電ユニット１０が効率的に冷却される。 In the present embodiment, when the wind passes through the space 3 formed between the power receiving unit 10 and the floor panel 2, the power receiving unit 10 is efficiently cooled.
　また、空間３を受電ユニット１０とフロアパネル２との間に形成することによって、例えば、電気自動車１の後退時に取付ユニット２０に縁石等が接触した場合や脱輪時にフロアパネル２の破損を防止することもできる。 Further, by forming the space 3 between the power receiving unit 10 and the floor panel 2, for example, when the electric vehicle 1 moves backward, a curb or the like comes into contact with the mounting unit 20 or the floor panel 2 is prevented from being damaged when the wheel is removed. You can also
　一方、取付ユニット２０の保護部材４０は、平面視において電気自動車１の車幅方向に延在する角筒の棒状部材であり、例えば、アルミニウム、又はアルミニウムを含む合金等から構成されている。 On the other hand, the protective member 40 of the mounting unit 20 is a rod-like member having a rectangular tube extending in the vehicle width direction of the electric vehicle 1 in plan view, and is made of, for example, aluminum or an alloy containing aluminum.
　保護部材４０をこうした透磁率が低く且つ導電率の高い材料で構成することで、非接触充電時に受電コイル１１と給電コイル５１との間に形成される磁束が後方に漏洩するのを抑制することができる。 By configuring the protection member 40 with a material having such a low magnetic permeability and high conductivity, it is possible to suppress the magnetic flux formed between the power receiving coil 11 and the power feeding coil 51 from leaking backward during non-contact charging. Can do.
　この保護部材４０は、図３及び図５に示すように、第２の支持部４１と、第２の固定部４２と、第２の屈曲部４３と、を有している。 The protective member 40 has a second support portion 41, a second fixing portion 42, and a second bent portion 43, as shown in FIGS.
　第２の支持部４１の上面４１１には、支持部材３０の第１の支持部３２の後端がボルト締結等によって固定されており（すなわち、保護部材４０は支持部材３０の下面３２１に固定されており）、保護部材４０は、支持部材３０の後端を支持している。この第２の支持部４１の両端には、第２の屈曲部４３を介して第２の固定部４２が繋がっており、保護部材４０は第２の固定部４２でフロアパネル２にボルト締結等によって固定されている。 The rear end of the first support portion 32 of the support member 30 is fixed to the upper surface 411 of the second support portion 41 by bolt fastening or the like (that is, the protection member 40 is fixed to the lower surface 321 of the support member 30). The protection member 40 supports the rear end of the support member 30. A second fixing portion 42 is connected to both ends of the second support portion 41 via a second bent portion 43, and the protection member 40 is bolted to the floor panel 2 by the second fixing portion 42. It is fixed by.
　本実施形態では、図２～図４に示すように、保護部材４０が受電ユニット１０の後方に設けられている。このため、電気自動車１の後退時に保護部材４０によって縁石等から受電ユニット１０を保護することができる。 In this embodiment, as shown in FIGS. 2 to 4, the protection member 40 is provided behind the power receiving unit 10. For this reason, the power receiving unit 10 can be protected from the curb or the like by the protective member 40 when the electric vehicle 1 is moved backward.
　また、本実施形態では、保護部材４０が、受電ユニット１０を支持している支持部材３０より下方に位置している。このため、電気自動車１の後退時や脱輪時に保護部材４０によって縁石等から受電ユニット１０を保護することができる。 In this embodiment, the protection member 40 is positioned below the support member 30 that supports the power reception unit 10. For this reason, the power receiving unit 10 can be protected from the curb or the like by the protective member 40 when the electric vehicle 1 is moved backward or removed.
　また、図２に示すように、保護部材４０の第２の支持部４１の下面４１２は、受電ユニット１０の下面１３（すなわち受電面１３）よりも下方に位置している。このため、電気自動車１の後退時や脱輪時に保護部材４０によって縁石等から受電ユニット１０を保護することができる。 Further, as shown in FIG. 2, the lower surface 412 of the second support portion 41 of the protection member 40 is located below the lower surface 13 (that is, the power receiving surface 13) of the power receiving unit 10. For this reason, the power receiving unit 10 can be protected from the curb or the like by the protective member 40 when the electric vehicle 1 is moved backward or removed.
　さらに、図５に示すように、第２の支持部４１及び第２の固定部４２は、フロアパネル２の平面方向にほぼ平行となっているのに対し、第２の屈曲部４３は、フロアパネル２の法線方向に対して傾斜している。このように第２の屈曲部４３を傾斜させることで保護部材４０の剛性が低くなるので、例えば、縁石との接触時や脱輪時に取付ユニット２０に加わる荷重を保護部材４０によって効率的に吸収することができる。 Further, as shown in FIG. 5, the second support portion 41 and the second fixing portion 42 are substantially parallel to the plane direction of the floor panel 2, whereas the second bent portion 43 is a floor. The panel 2 is inclined with respect to the normal direction. Since the rigidity of the protection member 40 is lowered by inclining the second bent portion 43 in this way, for example, the load applied to the mounting unit 20 at the time of contact with the curb or at the time of wheel removal is efficiently absorbed by the protection member 40. can do.
　以上のように、本実施形態では、支持部材３０を介して受電ユニット１０をフロアパネル２に取り付ける。これにより、電気自動車１の車高に依存することなく、支持部材３０の高さによって、受電コイル１１と給電コイル５１との間の距離を設定することができるので、非接触充電の送電効率の向上を図ることができる。 As described above, in the present embodiment, the power receiving unit 10 is attached to the floor panel 2 via the support member 30. Accordingly, the distance between the power receiving coil 11 and the power feeding coil 51 can be set depending on the height of the support member 30 without depending on the vehicle height of the electric vehicle 1, so that the power transmission efficiency of non-contact charging can be improved. Improvements can be made.
　しかも、本実施形態では、受電ユニット１０とフロアパネル２との間に一つの部材を介在させるだけであるので、簡単且つ低コストで送電効率の向上を図ることができる。 Moreover, in this embodiment, since only one member is interposed between the power receiving unit 10 and the floor panel 2, it is possible to improve power transmission efficiency easily and at low cost.
　また、受電ユニット１０とフロアパネル２との間に一つの部材を介在させるだけであるので、既存の電気自動車に対しても、非接触充電用の受電ユニット１０を簡単に後付けすることもできる。 Further, since only one member is interposed between the power receiving unit 10 and the floor panel 2, the power receiving unit 10 for non-contact charging can be easily retrofitted to an existing electric vehicle.
　さらに、本実施形態では、受電ユニット１０の背面１２と支持部材３０の下面３２１とが接触するように、受電ユニット１０が支持部材３０に固定されているので、受電ユニット１０の受電面１３は、支持部材３０で遮られることなく、下方に向かって露出している。このため、非接触充電時に受電コイル１１と給電コイル５１との間に形成される磁束が、支持部材３０によって妨げられてしまうことがない。 Furthermore, in this embodiment, since the power receiving unit 10 is fixed to the support member 30 so that the back surface 12 of the power receiving unit 10 and the lower surface 321 of the support member 30 are in contact, the power receiving surface 13 of the power receiving unit 10 is It is exposed downward without being blocked by the support member 30. For this reason, the magnetic flux formed between the power receiving coil 11 and the power feeding coil 51 during non-contact charging is not hindered by the support member 30.

　なお、以上説明した実施形態は、本発明の理解を容易にするために記載されたものであって、本発明を限定するために記載されたものではない。したがって、上記の実施形態に開示された各要素は、本発明の技術的範囲に属する全ての設計変更や均等物をも含む趣旨である。 The embodiment described above is described for easy understanding of the present invention, and is not described for limiting the present invention. Therefore, each element disclosed in the above embodiment is intended to include all design changes and equivalents belonging to the technical scope of the present invention.
　例えば、受電ユニット１０とフロアパネル２との間に空間３を形成しなくてもよい。この場合にも、受電ユニット１０とフロアパネル２との間に介在する支持部材の高さによって、受電コイル１１と給電コイル５１との間の距離を設定することができるので、非接触充電の送電効率の向上を図ることができる。 For example, the space 3 may not be formed between the power receiving unit 10 and the floor panel 2. Also in this case, since the distance between the power receiving coil 11 and the power feeding coil 51 can be set by the height of the support member interposed between the power receiving unit 10 and the floor panel 2, power transmission for non-contact charging is possible. Efficiency can be improved.
