To provide a side sill reinforcement structure for an electric vehicle which enables efficient improvement of battery protection performance.SOLUTION: A side sill reinforcement structure for an electric vehicle includes: a battery unit 10 for driving which is disposed at a lower part of a vehicle cabin R of an electric vehicle; a side sill 20 extending in a vehicle fore and aft direction at the outer side of the battery unit 10 when viewed in a vehicle width direction; and a reinforcement member 40 which connects the battery unit 10 with the side sill 20. The reinforcement member 40 is an extrusion member made of an aluminum alloy and has a closed cross section part group 40A in which closed cross section parts are connected in the vehicle width direction on a cross section perpendicular to the vehicle fore and aft direction. The closed cross section part group 40A includes: a first closed cross section part 41 disposed at the innermost side in the vehicle width direction; and a second closed cross section part 42 located adjacent to the first closed cross section part 41.SELECTED DRAWING: Figure 2
【課題】バッテリー保護性能を効率的に向上させる電動車両用サイドシル補強構造を提供する。【解決手段】電動車両用サイドシル補強構造は、電動車両の車室Rの下部に配置された駆動用のバッテリーユニット10と、バッテリーユニット10の車幅方向の外側において車両前後方向に延びるサイドシル20と、バッテリーユニット10およびサイドシル20を接続する補強部材40とを備える。補強部材40は、アルミニウム合金製の押出材であり、車両前後方向に垂直な断面において車幅方向に複数の閉断面部が連なった閉断面部群40Aを有している。閉断面部群40Aは、車幅方向の最も内側に配置された第1閉断面部41と、第1閉断面部41に隣接して配置された第2閉断面部42とを含む。【選択図】図2
