Abstract
Description
特に電気自動車においては、走行距離を大きくするために、二次電池の搭載重量が大きくなる。
しかし、電池モジュールの搭載量が大きくなれば車両に搭載した際の重量バランスが問題になるために電池モジュールの車両搭載フレームの軽量化が要求される。
特許文献1には、トランクルーム内のサイドメンバー間に配置したフロアパネルに電池を載置する技術を開示するが電池モジュールを車両に搭載するためのフレーム構造体に関するものではない。
ここで、車両サイドメンバーとは車体の骨組材をいう。
本明細書においては、車両の前側をフロント側と称し、車両の幅方向を左右方向と表現する。
また、フロントフレーム及びリアフレームはアルミ押出材で製作してあり、ベースフレームの両端部を架設する架設ブラケットを一体的に形成してもよい。
電池モジュールをフロント取付フレームとリア取付フレームとの間に橋渡しするように載置固定すると、電池モジュールの荷重は当該フロント取付フレームとリア取付フレームを支持するベースフレームに伝達される。
次にベースフレームに伝達された電池モジュールの荷重はこのベースフレームを支持するフロントフレームとリアフレームに伝達される。
さらにフロントフレームとリアフレームとは左右のサイドフレームに支持されているので電池モジュールの荷重は構成する各フレームに分散伝達されつつ、全重量を車両のサイドメンバーで支えることになる。
これにより、数百kgにも及ぶ電池モジュールの荷重が各フレームに分散伝達しつつ車両のサイドメンバーに伝達されるのでフレーム構造全体の軽量化を図りつつ、高剛性のフレーム構造が得られる。

図1,図2は車両の後部付近(トランクルーム)に本発明に係るフレーム構造体を取り付け例を示す。
車両の幅方向両側であって、車両の前後方向に延在する車両サイドメンバー1,1にフレーム構造体10を取り付ける。
図1は、車両にフレーム構造体10を取り付けた際の車両リア側から見た斜視図で図2は逆にフロント側から見た斜視図を示す。
図3は、フレーム構造体10のみを示した図である。
図4及び図5は説明のために、本発明に係るフレーム構造体10の上枠部分を取り外した図を示す。
サイドフレーム11は、車両前後方向のサイドメンバー1に沿って、前後方向に取り付けるための固定ブラケット11aを有し、この固定ブラケットに設けた取付孔11b等を介してサイドメンバー1に固定できるようになっている。
サイドフレーム11のフロント側端部には、左右のサイドフレーム間に橋渡しされるようにフロントフレーム13が架設されている。
一方、サイドフレーム11のリア側端部には、左右のサイドフレーム間に橋渡しされるようにリアフレーム12が架設されている。
まず、サイドフレーム11とリアフレーム12との架設連結構造について説明する。
図4(b)A部拡大図に示すように、サイドフレーム11の内側には押出加工にて一体的に成形した載置ブラケット11cを有し、この載置ブラケット11cにリアフレーム12に一体的に形成した連結ブラケット12bを重ねるように載置して連結ブラケット12bを載置ブラケット11cに溶接する。
なお、サイドフレーム11とリアフレーム12とのコーナー部にはリアコーナー縦フレーム14に一体的に設けた溶接ブラケット14b,14cにて側面溶接してある。
サイドフレーム11とフロントフレーム13とのコーナー部も図6のフレーム構造体10の底部側から見た斜視図に示すようにサイドフレーム11の載置ブラケット11cにフロントフレーム13の内側に張り出したフロント架設ブラケット13cを載置し、ブラケット間を溶接連結してある。
なお、フロント取付フレーム32及びリア取付フレーム31の両端部はスペーサーを介してサイドフレーム11の載置ブラケット11cに固定してもよい。
図4(a)にはスペーサー31bを用いている。
リアフレーム12には必要に応じて補強縦フレーム15を立設してある。
図4に示した状態で図示を省略した電池モジュールを固定ピン31a,32aにて載置固定する。
その上に上枠を取り付けて、電池モジュールを車両に搭載する。
上枠は、左右の上枠サイドフレーム21のフロント側を上枠フロントフレーム23で連結し、リア側を上枠リアフレーム22で連結した枠体にしてあり、必要に応じて補強フレーム24,25を前後方向,車幅方向に連結し、その上に冷却ユニット等を配置する。
上枠フロントフレーム21には予め、フロントコーナー縦フレーム16,補強縦フレーム17を連結してあり、上枠リアフレーム22をリアコーナー縦フレーム14,補強フレーム15の上部にボルト締結し、上枠フロントフレーム23から下方向に連結したフロントコーナー縦フレーム16,補強縦フレーム17の下端をフロントフレーム13の連結ブラケット13aに取付孔13bを用いてボルト等で固定する。
上枠フロントフレーム23は、アルミ押出材で製作してあり、上枠フロントフレーム23に一体的に形成した上下の溶接ブラケット23bの間に上枠サイドフレーム21の端部を呑み込ませるようして溶接してある。
同様に上枠フロントフレーム23とフロントコーナー縦フレーム16との連結も上枠フロントフレーム23に設けた左右の溶接ブラケット23aの間にフロントコーナー縦フレーム16の端部を呑み込ませるようにして溶接連結してある。
これにより、コーナー連結部の連結強度が向上する。
また、図6(a)に示すように上枠リアフレーム22にも溶接ブラケット22aを上下に設け、この間に上枠サイドフレーム21の端部を呑み込ませて溶接連結してある。
