Abstract

<P>PROBLEM TO BE SOLVED: To provide an inverter and an electric motor preventing a power-wire harness from breaking or disconnecting from a connector at the time of a vehicle collision even if the power-wire harness is not long. <P>SOLUTION: When a vehicle collides with an article 20, a suspension member 4 bends downward near a fragile portion B like as an arrow β, and a motor 5 on the member 4 moves in the same direction. Right and left side members 1, 2 absorb collision energy by crush of beads 1a, 2a, and then, front portions 1a, 2a bend downward relatively to high stiffness portions 1b, 2b around a boarder portion A of the both like as an arrow α. A front inverter mounting 11 displaces in the same direction with a front edge portion of the inverter 3. A rear inverter mounting 12 keeps a position on the high stiffness portions 1b, 2b, and rotates the inverter 3 in an arrow γ direction about the mounting 12 while twisted and deformed about an longitudinal axis. Therefore, the inverter 3 and the motor 5 move downward while keeping a relative position before collision, and the breakage of a power-wire harness 6 is prevented. Furthermore, a connecting portion 7a between the connector 3b and a power-wire harness 7 is kept at a generally same portion before and after the collision, and the breakage of the power-wire harness 7 is prevented. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

本発明は、電動モータにより車輪を駆動して走行する電動車両につき、パワーユニット、特に電動モータおよびインバータを、前部衝突時も強電ハーネスが断線したり、これが配電コネクタから外れて、走行不能になることのないようにした、パワーユニット搭載構造に関するものである。   The present invention relates to an electric vehicle that travels by driving wheels with an electric motor, and the power unit, particularly the electric motor and the inverter, is disconnected from the high-voltage harness even during a frontal collision, or is disconnected from the power distribution connector and cannot travel. The present invention relates to a power unit mounting structure that prevents this from happening.

上記のように、車両の前部衝突時も強電ハーネスが断線したり、これが配電コネクタから外れることのないようにする技術としては従来、例えば特許文献1に記載のようなものが知られている。
この技術は、電動車両の強電ハーネスの配索に工夫をこらして上記の要求を満足させようとするもので、パワーユニットを構成する部品間の車両前部衝突時の相対変位(部品の弾性支持による揺動分や、衝突による部品の移動に伴う部品間相対変位)を予め予測しておき、この部品間相対変位があっても強電ハーネスが断線したり、これが配電コネクタから外れることのないよう強電ハーネス長に余裕を持たせて強電ハーネスを配索するものである。

特開昭2000−152470号公報
As described above, conventionally, for example, a technique described in Patent Document 1 is known as a technique for preventing a high-voltage harness from being disconnected or being disconnected from a power distribution connector even at the time of a frontal collision of a vehicle. .
This technology is designed to satisfy the above requirements by devising the wiring of the high-voltage harness of the electric vehicle, and the relative displacement at the time of the vehicle front collision between the components constituting the power unit (by elastic support of the components). Predicting the amount of rocking and the relative displacement between components due to the movement of the component due to a collision) in order to prevent the high-voltage harness from being disconnected or coming off the power distribution connector even if this relative displacement occurs. The high-voltage harness is routed with a margin for the harness length.
According to such a countermeasure, the high-voltage harness is not disconnected even when the frontal collision of the vehicle occurs, and this does not come off from the power distribution connector, and the self-propellable state can be maintained even in the event of a light collision.
JP 2000-152470 A

しかし従来の技術にあっては、パワーユニット構成部品間相対変位を吸収し得るように強電ハーネス長に余裕を持たせて配索する対策であったため、強電ハーネスの配索に際し広いスペースが必要となり、スペース的にも作業上もパワーユニットの搭載性が低下してしまうという問題を生じたり、強電ハーネス同士の接触、摩耗に関する問題も発生し易いといった問題も生ずる。
また、強電ハーネス長を長くすることに起因して、インピーダンスの増加による電気的な効率の低下に関する問題を生じたり、更には、強電ハーネスの固定点増加に伴って、組込み作業工数の増加によるコスト高や、強電ハーネス固定具数の増加による重量増の問題を生ずる。
However, in the conventional technology, it was a measure to route the high-voltage harness with a margin so that the relative displacement between the power unit components can be absorbed, so a large space is required when wiring the high-voltage harness, There arises a problem that the mountability of the power unit is reduced in terms of space and work, and there is a problem that problems relating to contact between the high-voltage harnesses and wear are likely to occur.
In addition, due to the increase in the length of the high-voltage harness, there is a problem with a decrease in electrical efficiency due to an increase in impedance. The problem of an increase in weight due to an increase in the number of high-voltage and high-voltage harness fixtures arises.

本発明は、上記の問題がとりもなおさず、強電ハーネス長を長くすることに起因するとの事実認識に基づき、
パワーユニットを構成するインバータおよび電動モータの搭載構造に工夫を凝らして、強電ハーネス長を長くすることなく、車両の前部衝突時に強電ハーネスが断線したり、これが配電コネクタから外れるのを回避し得るようにしたパワーユニット搭載構造を提案し、もって上記従来対策の問題をことごとく解消することを目的とする。
The present invention is based on the fact that the above-mentioned problems are not solved and the high-voltage harness length is increased.
Innovate the mounting structure of the inverter and electric motor that make up the power unit, so that the high-voltage harness can be prevented from disconnecting or disconnecting from the power distribution connector at the time of a vehicle front collision without lengthening the high-voltage harness The proposed power unit mounting structure is proposed to solve all the problems of the conventional measures.

この目的のため本発明による電動車両のパワーユニット搭載構造は、請求項1に記載のごとくに構成する。
先ず前提となる電動車両は、インバータを介しバッテリからの電力で駆動される電動モータにより車輪を駆動する電動車両とする。
そして本発明は、上記インバータを車両前部のエンジンルーム内において車体の左右サイドメンバ上に搭載し、これらサイドメンバの下方に設けたサスペンションメンバ上に上記電動モータを搭載し、上記左右サイドメンバおよびサスペンションメンバがそれぞれ車両の前部衝突時に折れ曲がることで、インバータおよび電動モータの後方移動を抑制するようにした電動車両のパワーユニット搭載構造を前提とする。
For this purpose, the power unit mounting structure of an electric vehicle according to the present invention is constructed as described in claim 1.
First, the presupposed electric vehicle is an electric vehicle in which wheels are driven by an electric motor driven by electric power from a battery via an inverter.
In the present invention, the inverter is mounted on the left and right side members of the vehicle body in the engine room at the front of the vehicle, the electric motor is mounted on a suspension member provided below the side members, and the left and right side members and It is premised on a power unit mounting structure for an electric vehicle in which the suspension members are bent at the time of a frontal collision of the vehicle so that backward movement of the inverter and the electric motor is suppressed.

本発明は、かかるパワーユニット搭載構造におけるサスペンションメンバおよび左右サイドメンバをそれぞれ、車両の前部衝突時にこれらサスペンションメンバおよび左右サイドメンバが車体下方への折れ曲がるよう構成する。
そして、左右サイドメンバの折れ曲がりに伴ってインバータが、車体後方側取り付け点の位置を不変に保って該車体後方側取り付け点の周りで車体下方へ回動するよう、左右サイドメンバ、および、該左右サイドメンバに対するインバータの車体後方側取り付け部を構成し、これにより、
インバータおよび電動モータ間に延在する強電ハーネス用の、車体前方寄りに配置されたインバータ側配線コネクタおよびモータ側配線コネクタ間の距離が前部衝突前後でほぼ同じに保たれるようにすると共に、インバータおよびバッテリ間に延在する強電ハーネス用の、車体後方寄りに配置されたインバータ側配線コネクタの位置が前部衝突前後でほぼ同じに保たれるようする。
According to the present invention, the suspension member and the left and right side members in such a power unit mounting structure are configured such that the suspension member and the left and right side members bend downward in the vehicle body when the vehicle collides with the front.
Then, the left and right side members and the left and right side members are arranged so that the inverter rotates with the left and right side members bent around the vehicle rear side attachment point while keeping the position of the vehicle body rear side attachment point unchanged. Configure the vehicle body rear side mounting part of the inverter to the side member,
For the high-voltage harness extending between the inverter and the electric motor, the distance between the inverter-side wiring connector and the motor-side wiring connector arranged near the front of the vehicle body is kept substantially the same before and after the front collision, The position of the inverter-side wiring connector arranged near the rear of the vehicle body for the high-voltage harness extending between the inverter and the battery is kept substantially the same before and after the frontal collision.

かかる本発明の構成によれば、車両の前部衝突時にサスペンションメンバおよび左右サイドメンバが共に車体下方への折れ曲がることから、そして、左右サイドメンバの折れ曲がりに伴ってインバータが、車体後方側取り付け点の位置を不変に保ってこの点の周りで車体下方へ回動することから、
インバータおよび電動モータ間に延在する強電ハーネス用の、車体前方寄りに配置されたインバータ側配線コネクタおよびモータ側配線コネクタ間の距離が前部衝突前後でほぼ同じに保たれると共に、インバータおよびバッテリ間に延在する強電ハーネス用の、車体後方寄りに配置されたインバータ側配線コネクタの位置が前部衝突前後でほぼ同じに保たれることとなり、
車両の前部衝突時に強電ハーネスが断線したり、これが配電コネクタから外れるのを回避し得て、軽度の衝突であれば車両を自走させ得る状態に保つことができる。
According to such a configuration of the present invention, the suspension member and the left and right side members are both bent downward in the vehicle body at the time of a frontal collision of the vehicle, and the inverter is attached to the vehicle body rear side attachment point along with the bending of the left and right side members. Since it keeps its position unchanged and pivots around this point down the car body,
For the high-voltage harness extending between the inverter and the electric motor, the distance between the inverter-side wiring connector and the motor-side wiring connector arranged near the front of the vehicle body is kept substantially the same before and after the front collision, and the inverter and battery The position of the inverter-side wiring connector arranged near the rear of the vehicle body for the high-voltage harness extending in between will be kept substantially the same before and after the front collision,
It is possible to avoid disconnection of the high-voltage harness at the time of the frontal collision of the vehicle or disconnection from the power distribution connector, and it is possible to keep the vehicle in a state where it can be self-propelled if it is a slight collision.

そして、従来のように強電ハーネス長を長くすることなく上記の作用効果を達成し得ることから、強電ハーネスの配索に際して広いスペースが必要になることがなく、スペース的にも作業上もパワーユニットの搭載性が低下するという問題を生ずることがないし、強電ハーネス同士の接触、摩耗に関する懸念も減ずることができる。
また、強電ハーネス長を長くしないことから、インピーダンスの増加による電気的な効率低下の問題を生ずることもないし、強電ハーネスの固定点が増加することもなく、従って、組込み作業工数の増加によるコスト高や、強電ハーネス固定具数の増加による重量増の問題を生ずることもない。
In addition, since the above-described effects can be achieved without increasing the length of the high-voltage harness as in the prior art, a large space is not required for the wiring of the high-voltage harness. There is no problem that the mountability is lowered, and the concern about contact and wear between the high-voltage harnesses can be reduced.
In addition, since the length of the high-voltage harness is not increased, there is no problem of a decrease in electrical efficiency due to an increase in impedance, and there is no increase in the number of fixing points of the high-voltage harness. In addition, there is no problem of weight increase due to an increase in the number of high-voltage harness fixtures.

そして、インバータ3の車体前方寄りの前縁部は、左右サイドメンバ1,2の前部1a,2a間に橋絡して横架した前インバータマウンティング11を介し左右サイドメンバ1,2の前部1a,2a上に取り付ける。
また、インバータ3の車体後方寄りの後縁部は、左右サイドメンバ1,2の高剛性部1b,2b間に橋絡して横架した後インバータマウンティング12を介し左右サイドメンバ1,2の高剛性部1b,2b上に取り付ける。
When the inverter 3 is mounted on the left and right side members 1 and 2 as described above, the inverter 3 is disposed rearwardly by a predetermined distance L from the collapsed beads 1c and 2c as shown in FIG.
The front edge of the inverter 3 near the front of the vehicle body is connected to the front of the left and right side members 1 and 2 via a front inverter mounting 11 that is bridged between the front portions 1a and 2a of the left and right side members 1 and 2 Install on 1a, 2a.
In addition, the rear edge of the inverter 3 near the rear of the vehicle body is bridged between the high-rigidity portions 1b, 2b of the left and right side members 1, 2 and bridged horizontally, and then the height of the left and right side members 1, 2 via the inverter mounting 12 It is mounted on the rigid parts 1b and 2b.

前インバータマウンティング11は図1〜図3に示すように閉断面長尺ボックス形状としてその長手方向軸線周りの捻れ剛性が比較的高いものとする。
この前インバータマウンティング11の両端をそれぞれ図2および図3に示すように、ボルト&ナット手段13で左右サイドメンバ1,2の前部1a,2aに締結し、前インバータマウンティング11に対するインバータ3の前縁部の取り付けは、図1および図3に示すような2個のブラケット14を介してこれを行う。
As shown in FIGS. 1 to 3, the front inverter mounting 11 has a closed-section long box shape and has a relatively high torsional rigidity around its longitudinal axis.
As shown in FIGS. 2 and 3, both ends of the front inverter mounting 11 are fastened to the front portions 1a and 2a of the left and right side members 1 and 2 with bolts and nut means 13, and the front of the inverter 3 with respect to the front inverter mounting 11 is secured. The edge is attached via two brackets 14 as shown in FIGS.

後インバータマウンティング12は図1、図2および図4に示すように長尺チャンネル形状として、その長手方向軸線周りの捻れ剛性が前インバータマウンティング11のそれよりも低いものとする。
この後インバータマウンティング12の両端をそれぞれ図2および図4に示すように、左右サイドメンバ1,2の高剛性部1b,2bと接するフランジ部においてボルト&ナット手段15により左右サイドメンバ1,2の高剛性部1b,2bに締結し、後インバータマウンティング12に対するインバータ3の後縁部の取り付けは、図1および図4に示すような2個のブラケット16を介してこれを行う。

上記した実施例のパワーユニット搭載構造を持つ電動車両が、図5に示すように衝突対象物20に前部衝突した場合の作用を以下に説明する。
この前突時にサスペンションメンバ4は前端部を押されて脆弱部Bの付近で矢βで示すごとく車体下方へ折れ曲がり、これに伴い電動モータ5が同じ矢βで示すごとく車体後方および車体下方へ移動する。よって電動モータ5が車室に向けて後方移動されるのを抑制することができる。
この時の電動モータの移動量および移動方向は、サスペンションメンバ4に設ける脆弱部Bの設定箇所の調整により加減することができる。
The operation when the electric vehicle having the power unit mounting structure of the above-described embodiment collides front with the collision object 20 as shown in FIG. 5 will be described below.
At the time of this front collision, the suspension member 4 is pushed at the front end and bends downward in the vicinity of the fragile portion B as indicated by the arrow β, and accordingly, the electric motor 5 moves rearward and downward in the vehicle body as indicated by the same arrow β. To do. Therefore, it is possible to suppress the electric motor 5 from being moved backward toward the passenger compartment.
The amount and direction of movement of the electric motor at this time can be adjusted by adjusting the setting location of the weakened portion B provided on the suspension member 4.

左右サイドメンバ1,2は上記の衝突時に、前部1a,2a上の潰れビード1a,2aが図5のごとくに潰れて衝突エネルギーを吸収する。
一方で左右サイドメンバ1,2は、上記の衝突によっても変形しない高剛性部1b,2bを反力受けとして前部1a,2aが高剛性部1b,2bに対し相対的に、これら前部1a,2aおよび高剛性部1b,2b間の境界部Aの周りで矢αで示すごとく車体下方へ回動するよう折れ曲がる。
かように左右サイドメンバ1,2の前部1a,2aが折れ曲がることにより、前インバータマウンティング11がインバータ3の前縁部を伴って矢αで示すように変位する。
The left and right side members 1 and 2 collapse the crush beads 1a and 2a on the front portions 1a and 2a as shown in FIG.
On the other hand, the left and right side members 1 and 2 have the front portions 1a and 2a that are relatively deformed relative to the high-rigidity portions 1b and 2b with the high-rigidity portions 1b and 2b that are not deformed by the above-described collision as a reaction force. , 2a and the high-rigidity portions 1b, 2b are bent so as to rotate downward as shown by an arrow α around the boundary A.
By bending the front portions 1a and 2a of the left and right side members 1 and 2 as described above, the front inverter mounting 11 is displaced along with the front edge portion of the inverter 3 as indicated by an arrow α.

ところで後インバータマウンティング12は、高剛性部1b,2b上にあってインバータ3の後縁部取り付け点位置を不変に保つ。
しかし後インバータマウンティング12が前記した通り、その長手方向軸線周りの捻れ剛性を前インバータマウンティング11のそれよりも小さくされていることから、前インバータマウンティング11(インバータ3の前縁部)の上記した変位αは、後インバータマウンティング12をその長手方向軸線周りに捻れ変形させながら、インバータ3をその後方側取り付け点(後インバータマウンティング12)の周りに矢γで示す方向へ回動させる。
By the way, the rear inverter mounting 12 is on the high-rigidity portions 1b and 2b and keeps the position of the rear edge portion attachment point of the inverter 3 unchanged.
However, as described above, since the rear inverter mounting 12 has a torsional rigidity around its longitudinal axis smaller than that of the front inverter mounting 11, the above-described displacement of the front inverter mounting 11 (the front edge of the inverter 3). α turns the inverter 3 around its rear attachment point (rear inverter mounting 12) in the direction indicated by the arrow γ while twisting and deforming the rear inverter mounting 12 about its longitudinal axis.

以上により、前部衝突時にインバータ3および電動モータ5が衝突前の相対位置を保って車体下方へ移動することとなり、インバータ3および電動モータ5間に延在する強電ハーネス6用の、車体前方寄りに配置されたインバータ側配線コネクタ3aおよびモータ側配線コネクタ5a間の距離を前部衝突前後でほぼ同じに保つことができ、強電ハーネス6が断線したり、配線コネクタ3a, 5aから外れるのを防止することができる。
また上記の衝突時に、インバータ3が後方側取り付け点(後インバータマウンティング12)の位置を不変に保たれたまま、当該取り付け点の周りに矢γで示す方向へ回動されることから、車体後方寄りに配置された配電コネクタ3bと強電ハーネス7との接続点7aが、図6(a)に二点鎖線で示すインバータ3の衝突前位置および実線で示す衝突後位置の比較から明らかなように、衝突の前後でほぼ同じ位置に保たれる。よって、強電ハーネス7が断線したり、配線コネクタ3bから外れるのを防止することができる。
As a result, the inverter 3 and the electric motor 5 move downward in the vehicle body while maintaining the relative positions before the collision at the time of the front collision, and the front side of the vehicle body for the high-voltage harness 6 extending between the inverter 3 and the electric motor 5 The distance between the inverter-side wiring connector 3a and the motor-side wiring connector 5a placed in the front can be kept almost the same before and after the front collision, preventing the high-voltage harness 6 from being disconnected or coming off the wiring connectors 3a, 5a can do.
Further, at the time of the collision, the inverter 3 is rotated around the attachment point in the direction indicated by the arrow γ while the position of the rear attachment point (rear inverter mounting 12) is kept unchanged. As shown in FIG. 6 (a), the connection point 7a between the power distribution connector 3b and the high-voltage harness 7 disposed closer to each other is clear from the comparison between the position before the collision of the inverter 3 indicated by the two-dot chain line and the position after the collision indicated by the solid line. , Kept in almost the same position before and after the collision. Therefore, it is possible to prevent the high-voltage harness 7 from being disconnected or disconnected from the wiring connector 3b.

ちなみに図6(b)に示すごとく、後インバータマウンティング12(インバータ3の後方側取り付け点)が前インバータマウンティング11(インバータ3の前方側取り付け点)と同じく、サイドメンバ1,2の折れ曲がる前部1a,2a上にあって、上記の衝突時に、サイドメンバ前部1a,2aの折れ曲がりに伴ってインバータ3の後方側取り付け点(後インバータマウンティング12)がインバータ3の前方側取り付け点(前インバータマウンティング11)と同方向へ変位する場合、車体後方寄りに配置された配電コネクタ3bと強電ハーネス7との接続点7aは、図6(b)に二点鎖線で示すインバータ3の衝突前位置および実線で示す衝突後位置の比較から明らかなように、衝突の前後で大きく(Dにより示す)位置を変化される。
よって、強電ハーネス7が断線したり、配線コネクタ3bから外れる懸念があるが、本実施例では上記のように、この懸念を払拭することができる。
By the way, as shown in Fig. 6 (b), the rear inverter mounting 12 (the mounting point on the rear side of the inverter 3) is the same as the front inverter mounting 11 (the mounting point on the front side of the inverter 3). , 2a and at the time of the collision, the rear attachment point of the inverter 3 (rear inverter mounting 12) becomes the front attachment point of the inverter 3 (front inverter mounting 11 in accordance with the bending of the front portions 1a, 2a of the side members. )), The connection point 7a between the power distribution connector 3b and the high-voltage harness 7 arranged closer to the rear of the vehicle body is the position before the collision of the inverter 3 indicated by a two-dot chain line in FIG. 6 (b) and a solid line. As is clear from the comparison of the post-collision positions shown, the position is greatly changed (indicated by D) before and after the collision.
Therefore, although there is a concern that the high-voltage harness 7 may be disconnected or disconnected from the wiring connector 3b, this concern can be eliminated as described above in the present embodiment.

以上のように本実施例によれば、車両の軽い前部衝突なら、インバータ3の前後に配索した強電ハーネス6,7が断線したり、これら強電ハーネス6,7が配電コネクタ3a,5aおよび3bから外れるのを回避し得て、車両を自走させ得る状態に保つことができるが、
かかる作用効果を、従来のような強電ハーネス長の延長に頼ることなく達成し得ることから、強電ハーネス6,7の配索に際して広いスペースが必要になることがなく、スペース的にも作業上も電動車両用パワーユニットの搭載性が低下するという問題を生ずることがないし、強電ハーネス同士の接触、摩耗に関する懸念も減ずることができる。
また、強電ハーネス長を長くしないことから、インピーダンスの増加による電気的な効率低下の問題を生ずることもないし、強電ハーネスの固定点が増加することもなく、従って、組込み作業工数の増加によるコスト高や、強電ハーネス固定具数の増加による重量増の問題を生ずることもない。
As described above, according to this embodiment, in the case of a light frontal collision of the vehicle, the high-voltage harnesses 6 and 7 wired before and after the inverter 3 are disconnected, or the high-voltage harnesses 6 and 7 are connected to the distribution connectors 3a and 5a and You can avoid getting out of 3b and keep the vehicle in a self-propelled state,
Since this effect can be achieved without relying on the extension of the length of the high-voltage harness as in the prior art, a large space is not required for the wiring of the high-voltage harnesses 6 and 7, and both space and work are required. There is no problem that the mountability of the power unit for an electric vehicle is lowered, and the concern about contact and wear between the high-voltage harnesses can be reduced.
In addition, since the length of the high-voltage harness is not increased, there is no problem of a decrease in electrical efficiency due to an increase in impedance, and there is no increase in the number of fixing points of the high-voltage harness. In addition, there is no problem of weight increase due to an increase in the number of high-voltage harness fixtures.

なお上記実施例では、衝突時にサイドメンバ前部1a,2aの折れ曲がりに伴いインバータ3が後方側取り付け点(後インバータマウンティング12)の周りに矢γ(図5および図6参照)で示す方向へ回動するようになすに際し、後インバータマウンティング12の長手方向軸線周りにおける捻れ変形により当該インバータ3の回動を生起させるようにしたが、この代わりに、後インバータマウンティング12を用いない図7および図8に示すようなインバータ3の車体後方側枢支取り付け構造とするのがよい。   In the above embodiment, the inverter 3 rotates in the direction indicated by the arrow γ (see FIGS. 5 and 6) around the rear attachment point (rear inverter mounting 12) as the side member front portions 1a and 2a are bent at the time of collision. In order to make it move, the rotation of the inverter 3 is caused by torsional deformation around the longitudinal axis of the rear inverter mounting 12, but instead, the rear inverter mounting 12 is not used. It is preferable to adopt a pivot mounting structure for the rear side of the inverter 3 as shown in FIG.

つまり、サイドメンバ1,2の高剛性部1b,2b上にそれぞれ図7および図8(a),(b)に示すごとく筒状インシュレータ21をボルト&ナット手段22により取着して設ける。
これら筒状インシュレータ21は、内筒21aと、これを包套する外筒21bと、これら内外筒21a,21b間に加硫接着した弾性ブッシュ21cとで構成し、その中心位置が前記した後インバータマウンティング12(図1、図2および図4参照)の長手方向軸線に一致するよう配置する。
そして、インバータ3に図7および図8(a),(c)に示すごとくブラケット23をボルト&ナット手段24により取着して設ける。
筒状インシュレータ21の内筒21a内に枢支軸25を貫通して設け、内筒21aから吐出する枢支軸25の端部をブラケット23に回転自在に挿通する。
That is, the cylindrical insulator 21 is attached to the high rigidity portions 1b and 2b of the side members 1 and 2 by bolts and nuts 22 as shown in FIGS. 7 and 8 (a) and 8 (b).
These cylindrical insulators 21 are composed of an inner cylinder 21a, an outer cylinder 21b surrounding the inner cylinder 21a, and an elastic bush 21c vulcanized and bonded between the inner and outer cylinders 21a, 21b. Arranged to coincide with the longitudinal axis of the mounting 12 (see FIGS. 1, 2 and 4).
Then, as shown in FIGS. 7 and 8 (a) and 8 (c), the inverter 23 is provided with the bracket 23 attached by the bolt and nut means 24.
A pivot shaft 25 is provided through the inner cylinder 21a of the cylindrical insulator 21, and an end portion of the pivot shaft 25 discharged from the inner cylinder 21a is rotatably inserted into the bracket 23.

本実施例では、衝突時にサイドメンバ前部1a,2aの前記折れ曲がりに伴いインバータ3が、位置を不変に保たれている枢支軸25の周りに矢γ(図5および図6参照)で示す方向へ回動して前記した実施例と同様の作用効果を奏し得るが、インバータ3の車体後方側取り付け構造が枢支取り付け構造であるため、インバータ3の上記回動を一層確実に行わせることができて前記の作用効果を一層顕著なものにし得る。
なお、この作用効果だけのためなら筒状インシュレータ21は必ずしも必要ではないが、本実施例のように筒状インシュレータ21を用いる場合、その弾性ブッシュ21cがインバータ3の振動に弱い内蔵部品を防振する機能を果たして、耐久性を向上させることができるし、弾性ブッシュ21cは更に漏電防止作用をも果たして大いに有用である。
In this embodiment, the inverter 3 is indicated by an arrow γ (see FIGS. 5 and 6) around the pivot shaft 25 whose position is kept unchanged as the side member front portions 1a and 2a are bent at the time of collision. Although it can be rotated in the direction to achieve the same effect as the above-described embodiment, the vehicle body rear side mounting structure of the inverter 3 is a pivotal mounting structure, so that the rotation of the inverter 3 can be more reliably performed. And the above-mentioned effects can be made more remarkable.
Note that the cylindrical insulator 21 is not necessarily required only for this function and effect. However, when the cylindrical insulator 21 is used as in this embodiment, the elastic bush 21c dampens a built-in component that is weak against the vibration of the inverter 3. The durability of the elastic bushing 21c can be improved by fulfilling the function to achieve this, and the elastic bushing 21c is further useful for preventing leakage.
