Description

本発明は、コイルユニットに関し、詳しくは、コイルと、電気機器と、前記コイルと前記電気機器とを接続する第1配線および第2配線と、が収容ケース内に収容されてなるコイルユニットに関する。   The present invention relates to a coil unit, and more particularly, to a coil unit in which a coil, an electrical device, and a first wiring and a second wiring that connect the coil and the electrical device are accommodated in a housing case.

従来、この種のコイルユニットとしては、所定周波数に変換された交流電力が入力される一次コイルを収容ケースに収容し、一次コイルと車両に設けられた二次コイルとの間の共振により非接触で車両に電力を送電するものが提案されている(例えば、特許文献1参照)。このコイルユニットでは、収容ケース内の一次コイルの周囲に異物を検知するための検知コイルを設け、検知コイルに接続された共振回路からの出力に基づいて異物の存在の有無を判定している。   Conventionally, as this type of coil unit, a primary coil to which AC power converted to a predetermined frequency is input is housed in a housing case, and contactless due to resonance between the primary coil and a secondary coil provided in the vehicle. A device for transmitting electric power to a vehicle is proposed (for example, see Patent Document 1). In this coil unit, a detection coil for detecting foreign matter is provided around the primary coil in the housing case, and the presence or absence of foreign matter is determined based on the output from the resonance circuit connected to the detection coil.

ところで、近年、システム全体の小型化のために、コイルユニットとしてコイルと共にコイルに電力を供給するための電気機器を収容ケース内に収容することが提案されている。こうしたコイルユニットでは、コイルに形成される磁界によって電気機器が影響を受ける場合がある。こうした影響を低減する手法として、収容ケース内の空間を仕切り壁で2つに分割して、一方にコイルを収容し、他方に電気機器を収容し、コイルと電気機器とを接続する配線を貫通させるための貫通孔を仕切り壁に形成する手法がある。しかしながら、この手法では、仕切り壁に貫通孔を形成する際に、収容ケースの側壁に工具を挿入するための作業用の貫通孔を形成する必要がある。こうして形成された側壁部の貫通孔は、仕切り壁の貫通孔の形成後はグロメットなどで塞がれて活用されていない。   Incidentally, in recent years, in order to reduce the size of the entire system, it has been proposed to house an electric device for supplying power to the coil as a coil unit in the housing case. In such a coil unit, an electric device may be affected by a magnetic field formed in the coil. To reduce this effect, the space inside the housing case is divided into two by a partition wall, the coil is housed in one side, the electrical device is housed in the other, and the wiring connecting the coil and the electrical device is passed through. There is a method of forming a through hole in the partition wall for the purpose. However, in this method, when the through hole is formed in the partition wall, it is necessary to form a work through hole for inserting a tool into the side wall of the housing case. The through hole in the side wall portion formed in this way is not used because it is closed with a grommet after the through hole in the partition wall is formed.

FIG. 5 is an external view showing an outline of the external appearance of the housing 42, and FIG. 6 is a plan view showing the storage case 40 viewed from the direction B in FIG. .

収容ケース40は、図2〜図4に示すように、アルミニウムなどの金属材料により形成されて図中上面が開口した筐体42と、筐体42の蓋を構成するコイルカバー52および電源部カバー54とを備える。   As shown in FIGS. 2 to 4, the housing case 40 includes a housing 42 formed of a metal material such as aluminum and having an upper surface opened in the drawing, a coil cover 52 that constitutes a lid of the housing 42, and a power source cover. 54.

筐体42は、底面を構成する矩形形状の底部44と、底部44の各端辺から立設する側壁部46a〜46dと、側壁部46bと側壁部46dとに亘るよう底部44から立設する仕切り壁部48とを備える。   The casing 42 is erected from the bottom part 44 so as to cover the rectangular bottom part 44 constituting the bottom surface, the side wall parts 46 a to 46 d erected from each end of the bottom part 44, and the side wall part 46 b and the side wall part 46 d. A partition wall 48.

仕切り壁部48は、図3〜図5に示すように、収容ケース40内の空間をコイル収容空間50aと電源回路収容空間50bとに仕切るよう形成されている。コイル収容空間50aには、図示はしないが、送電用コイル32aなど送電用共振回路32を構成する電気部品が収容されている。電源回路収容空間50bには、図示はしないが、高周波電源回路34を構成する各種電子部品が収容されている。このように送電用共振回路32を構成する電子部品と高周波電源回路34を構成する電子部品とを1つの収容ケース40内に収容することにより、システム全体の小型化を図っている。   As shown in FIGS. 3 to 5, the partition wall 48 is formed so as to partition the space in the housing case 40 into a coil housing space 50 a and a power circuit housing space 50 b. Although not shown, the coil housing space 50a houses electrical components that constitute the power transmission resonance circuit 32 such as the power transmission coil 32a. Although not shown, the power circuit housing space 50b houses various electronic components constituting the high frequency power circuit 34. As described above, the electronic components constituting the power transmission resonance circuit 32 and the electronic components constituting the high-frequency power supply circuit 34 are accommodated in one accommodation case 40, thereby reducing the size of the entire system.

仕切り壁部48は、図3〜図5に示すように、貫通孔48a,48bを備えている。貫通孔48aには、図4に示すように、コイル収容空間50a内に収容された電子部品と電源回路収容空間50b内に収容された高周波電源回路34とを接続するワイヤハーネスWH1が貫通している。貫通孔48bには、貫通孔48aと同様に、コイル収容空間50a内に収容された電子部品と電源回路収容空間50b内に収容された高周波電源回路34とを接続するワイヤハーネスWH2が貫通している。   As shown in FIGS. 3 to 5, the partition wall 48 includes through holes 48 a and 48 b. As shown in FIG. 4, a wire harness WH1 that connects the electronic component housed in the coil housing space 50a and the high-frequency power circuit 34 housed in the power circuit housing space 50b passes through the through hole 48a. Yes. Similar to the through hole 48a, the wire harness WH2 connecting the electronic component housed in the coil housing space 50a and the high frequency power circuit 34 housed in the power circuit housing space 50b penetrates through the through hole 48b. Yes.

側壁部46a〜46dのうち仕切り壁部48の電源回路収容空間50b側において仕切り壁部48に対向する側壁部46aは、図3,図5,図6に示すように、貫通孔46e,46fを備えている。貫通孔46eは、貫通孔48aに対向する位置に、貫通孔48aを側壁部46aに投影した投影図形より外形が大きくなるよう形成されている。貫通孔46eには、交流電源90と高周波電源回路34とを接続するワイヤハーネスWH3が貫通している。貫通孔46fは、貫通孔48bに対向する位置に、貫通孔48bを側壁部46aに投影した投影図形より外形が大きくなるよう形成されている。貫通孔46fには、収容ケース40内の圧力を調整する圧力調整弁50が取り付けられている。貫通孔46e,46fは、貫通孔46e,46fに対向する位置に、貫通孔48a,48bを側壁部46aに投影した投影図形より外形が大きくなるよう形成されているから、仕切り壁部48に工具で貫通孔48a,48bを形成する際に、貫通孔46e,46fを収容ケース40の外側から工具を挿入するための作業用の貫通孔として用いることができる。また、貫通孔46e,46fは、貫通孔48a,48bを形成した後は、ワイヤハーネスWH3を貫通させたり圧力調整弁50を取り付けたりするための孔として用いることができる。したがって、貫通孔46e,46fにグロメットなどを取り付けて貫通孔46e,46fを塞ぐものと比較すると、貫通孔46e,46fの活用を図ることができる。   Of the side wall portions 46a to 46d, the side wall portion 46a facing the partition wall portion 48 on the power circuit housing space 50b side of the partition wall portion 48 has through holes 46e and 46f as shown in FIGS. I have. The through hole 46e is formed at a position facing the through hole 48a so as to have an outer shape larger than the projected figure obtained by projecting the through hole 48a onto the side wall portion 46a. A wire harness WH3 that connects the AC power supply 90 and the high frequency power supply circuit 34 passes through the through hole 46e. The through hole 46f is formed at a position facing the through hole 48b so that the outer shape is larger than the projected figure obtained by projecting the through hole 48b onto the side wall portion 46a. A pressure regulating valve 50 that regulates the pressure in the housing case 40 is attached to the through hole 46f. The through holes 46e and 46f are formed at the positions facing the through holes 46e and 46f so that the outer shape is larger than the projected figure obtained by projecting the through holes 48a and 48b onto the side wall part 46a. When the through holes 48 a and 48 b are formed, the through holes 46 e and 46 f can be used as work through holes for inserting a tool from the outside of the housing case 40. Moreover, after forming the through holes 48a and 48b, the through holes 46e and 46f can be used as holes for penetrating the wire harness WH3 or attaching the pressure regulating valve 50. Therefore, the through holes 46e and 46f can be used more effectively than a case where a grommet or the like is attached to the through holes 46e and 46f to close the through holes 46e and 46f.

コイルカバー52は、樹脂などの非金属材料により形成されており、コイル収容空間50aの上面を覆っている。コイルカバー52は、樹脂などの非金属により形成されているから、送電用コイル32aと受電用コイルとの間の電磁場を介した共鳴を良好に行なわせることができる。   The coil cover 52 is formed of a non-metallic material such as resin and covers the upper surface of the coil housing space 50a. Since the coil cover 52 is formed of a non-metal such as resin, the resonance through the electromagnetic field between the power transmission coil 32a and the power reception coil can be favorably performed.
