【発明の属する技術分野】
この発明は車両の電力線の配設構造に係り、特に、走行用モータとバテッリとの間を連絡する太い電力線を、小さい曲率で湾曲させることなくサイドメンバに沿って配設し得て、ステアリングギヤケースとの干渉を回避しつつ容易に配設し得る車両の電力線の配設構造に関する。
【0002】
【従来の技術】
車両には、推進装置の動力源として走行用モータを有するパワーユニットを搭載し、走行用モータにバッテリから電力を供給して走行するものがある。この車両は、走行用モータとバッテリとを接続する電力線を車体に配設している。
【0003】
従来の車両の電力線の配設構造には、電気自動車の車幅方向略中央に車両前後方向に指向してフロア本体に一体的に成型されるトンネル部と、このトンネル部に車両前後方向に指向して装着されるカバー部材とを備え、トンネル部内にはブレーキワイヤ等のワイヤ類を収容する第1室が形成され、トンネル部とカバー部材との間には第1室から分離されて電力ケーブルをフロア本体上に支持させた状態で収容可能な第2室を形成して設けたものがある(例えば、特許文献1参照。)。
また、従来の車両の電力線の配設構造には、前後車軸間の床下に配したバッテリの正極給電線及び負極給電線のうちの一方を、バッテリケースの車幅方向の一方の側面から、他方を他方の側面から引き出し、引き出した両給電線を夫々左右のフェンダ外板とフェンダ内板とで囲まれる空間を経由してモータルーム内に導入したものである(例えば、特許文献2参照。)。
さらに、従来の車両の電力線の配設構造には、車両前後方向中央下部又は後部に搭載したバッテリと、車両前方のフロントルーム内に配設した電気機器と、ダッシュパネル外側に沿ってバッテリから電気機器へ延びる電力線とを有する配線構造において、ダッシュパネル下部に車幅方向に沿って配設され、このダッシュパネル下部とで車幅方向へ延びる閉じ断面を形成する補強メンバを有し、閉じ断面を車両前後方向に貫通する貫通孔を通して電力線を配設したものがある(例えば、特許文献3参照。)。

【発明が解決しようとする課題】
ところで、従来の車両の電力線の配設構造には、推進装置の動力源として少なくとも走行用モータを有するパワーユニットを車体前部のエンジンルームに搭載し、エンジンルームを仕切るダッシュパネルの後側の車体後部にバッテリを搭載し、走行用モータとバッテリとを接続する電力線を車体に配設したものがある。走行用モータから引き出された電力線は、下側に延びてダッシュパネルの下側に沿って車体後部のバッテリまで導かれる。
【0006】
ところが、車両には、ダッシュパネルの下部に車両幅方向に延びる筒状に形成されたステアリングギヤケースを装着して設けているものがある。この車両においては、走行用モータから引き出された電力線をダッシュパネルに沿い下側に向かって配設すると、ダッシュパネルの下部においてステアリングギヤケースと干渉することになる。
【0007】
このため、電力線をダッシュパネルに沿い下側に向かって配設する場合には、ステアリングギヤケースとの干渉により配設することが困難な問題があり、ステアリングギヤケースとの干渉を回避すべく電力線を湾曲させると、ダッシュパネルから電力線が離間して固定することが困難となり、振動等により電力線が振れて周辺部品との干渉を招くおそれがある。
【0008】
また、電力線をダッシュパネルに沿い下側に向かって配設する場合には、周辺部品との干渉を回避するために、太い動力線をステアリングギヤケースに沿って小さい曲率半径で湾曲させる必要が生じ、電力線の配設が困難になる不都合があった。
【0009】
【課題を解決するための手段】
そこで、この発明は、上述の不都合を除去するために、車両前後方向に延びる左右一対の左・右サイドメンバを設け、車両幅方向に延設されて前記左・右サイドメンバの後端部を連絡するダッシュパネルを設け、このダッシュパネルの前側であって前記左・右サイドメンバ間の車体前部に搭載されて少なくとも走行用モータを有するパワーユニットを設け、車両幅方向に延びる筒状に形成されて前記ダッシュパネルの下部に装着されるステアリングギヤケースを設け、前記ダッシュパネルよりも後側の車体後部に搭載されるバッテリを設け、前記走行用モータと前記バッテリとの間を接続する電力線を車体に配設した車両の電力線の配設構造において、前記電力線を前記走行用モータから前記左・右サイドメンバのいずれか一方に沿って下側に延出して設け、前記ステアリングギヤケースよりも下側の位置で前記左・右サイドメンバのいずれか一方と前記ダッシュパネルとを連絡する支持部材を設け、この支持部材に沿って前記電力線を前記左・右サイドメンバのいずれか一方の側から前記ダッシュパネル側に向かい延設したことを特徴とする。
【0010】
【発明の実施の形態】
この発明の車両の電力線の配設構造は、電力線を走行用モータから左・右サイドメンバのいずれか一方に沿って下側に延出して設け、ステアリングギヤケースよりも下側の位置で左・右サイドメンバのいずれか一方とダッシュパネルとを連絡する支持部材を設け、この支持部材に沿って電力線を左・右サイドメンバのいずれか一方の側からダッシュパネル側に向かい延設したことにより、電力線を小さい曲率半径で湾曲させることなく、ステアリングギヤケースとの干渉を回避しながら、ダッシュパネルの下側に沿うように支持部材によって支持することができる。

The present invention relates to an arrangement structure of a power line of a vehicle, and in particular, a thick power line communicating between a driving motor and a battery can be arranged along a side member without bending with a small curvature, and a steering gear case The present invention relates to a power line arrangement structure of a vehicle that can be easily arranged while avoiding interference with the vehicle.
[0002]
[Prior art]
Some vehicles have a power unit having a traveling motor as a power source of the propulsion device, and travel by supplying electric power from a battery to the traveling motor. In this vehicle, a power line that connects a traveling motor and a battery is disposed on the vehicle body.
[0003]
In a conventional vehicle power line arrangement structure, there is a tunnel portion that is integrally molded with the floor body in the vehicle longitudinal direction substantially at the center in the vehicle width direction of the electric vehicle, and the vehicle portion is oriented in the vehicle longitudinal direction. And a cover member to be mounted, and a first chamber for accommodating wires such as a brake wire is formed in the tunnel portion, and the power cable is separated from the first chamber between the tunnel portion and the cover member. Is formed and provided with a second chamber that can be accommodated while being supported on the floor body (see, for example, Patent Document 1).
In addition, in the conventional vehicle power line arrangement structure, one of the positive and negative electrode feeders of the battery disposed under the floor between the front and rear axles is connected to the other side of the battery case from one side in the vehicle width direction. Is pulled out from the other side surface, and both the drawn feeder lines are introduced into the motor room via spaces surrounded by the left and right fender outer plates and the fender inner plates (see, for example, Patent Document 2). .
Furthermore, the conventional power line arrangement structure of the vehicle includes a battery mounted at the center lower part or rear part in the vehicle front-rear direction, an electric device provided in the front room in front of the vehicle, and an electric power from the battery along the outside of the dash panel. In a wiring structure having a power line extending to a device, the wiring structure is disposed along the vehicle width direction at the lower portion of the dash panel, and has a reinforcing member that forms a closed cross section extending in the vehicle width direction with the lower portion of the dash panel.

JP-A-8-67273 (second page, FIGS. 1 and 2)
[0005]
[Problems to be solved by the invention]
By the way, in the conventional vehicle power line arrangement structure, a power unit having at least a traveling motor as a power source of the propulsion device is mounted in the engine room in the front part of the vehicle body, and the vehicle body rear part on the rear side of the dash panel that partitions the engine room A battery is mounted on the vehicle body, and a power line for connecting the traveling motor and the battery is provided on the vehicle body. The power line drawn from the traveling motor extends downward and is guided to the battery at the rear of the vehicle body along the lower side of the dash panel.
[0006]
However, some vehicles are provided with a steering gear case formed in a cylindrical shape extending in the vehicle width direction at the lower portion of the dash panel. In this vehicle, if the power line drawn from the traveling motor is disposed downward along the dash panel, it interferes with the steering gear case at the lower part of the dash panel.

For this reason, when the power line is arranged downward along the dash panel, there is a problem that it is difficult to arrange the power line due to interference with the steering gear case, and the power line is bent to avoid interference with the steering gear case. If it does, it will become difficult to isolate | separate and fix a power line from a dash panel, and there exists a possibility of causing a power line to shake by vibration etc. and causing interference with peripheral components.
[0008]
In addition, when the power line is arranged downward along the dash panel, it is necessary to bend the thick power line with a small radius of curvature along the steering gear case in order to avoid interference with peripheral parts, There is a disadvantage that it is difficult to arrange the power line.
[0009]
[Means for Solving the Problems]
Therefore, in order to eliminate the above-described inconvenience, the present invention provides a pair of left and right side members extending in the vehicle front-rear direction, and extends in the vehicle width direction so that the rear end portions of the left and right side members are disposed. A dash panel for contact is provided, and a power unit mounted at the front of the vehicle body between the left and right side members on the front side of the dash panel and having at least a traveling motor is provided, and is formed in a cylindrical shape extending in the vehicle width direction. A steering gear case mounted on the lower portion of the dash panel, a battery mounted on the rear of the vehicle body behind the dash panel, and a power line connecting the driving motor and the battery to the vehicle body. In the arrangement structure of the electric power line of the arranged vehicle, the electric power line is lowered from the traveling motor along one of the left and right side members. A support member is provided to extend and provide a support member that communicates either the left or right side member with the dash panel at a position below the steering gear case, and the power line is connected to the left and right along the support member. It is characterized by extending from either one side of the right side member toward the dash panel side.
[0010]
