To protect a power control unit, a cabin, and a battery chamber from an impact load caused during a front collision.SOLUTION: A front frame structure for an electric vehicle includes: a pair of left and right front side frames disposed on both sides in a vehicle width direction of a motor room provided in a front part of a vehicle body and extending in a front-rear direction of the vehicle body; impact absorbing members disposed at front ends of the respective front side frames; a bumper beam coupling the left and right impact absorbing members; and a lower frame disposed in a lower part of the motor room and supported on both sides in the vehicle width direction by the front side frames. Each front side frame is disposed in an extra space defined between a side wall in the vehicle width direction of the motor room and a side surface of a power control unit. A frame-shaped rigid member is disposed in an extra space in a front part of the motor room. The front side frames are coupled to a rear surface of the frame-shaped rigid member and the impact absorbing members are coupled to a front surface of the frame-shaped rigid member.SELECTED DRAWING: Figure 2

    【課題】前面衝突時の衝撃荷重からパワーコントロールユニット、キャビン、バッテリ室を保護する。【解決手段】電気自動車用フロントフレーム構造は、車体の前部に設けたモータルームの車幅方向両側に配設されて該車体の前後方向へ延在する左右一対のフロントサイドフレームと、各フロントサイドフレームの前端に配設した衝撃吸収部材と、左右の衝撃吸収部材を結合するバンパビームと、モータルームの下部に配設されて車幅方向両側が各フロントサイドフレームに支持されているロアフレームとを備え、モータルームの車幅方向側壁とパワーコントロールユニットの側面との間の余剰空間にフロントサイドフレームが配設され、モータルームの前部の余剰空間に枠状剛性部材が配設され、枠状剛性部材の後面にフロントサイドフレームが結合され、該枠状剛性部材の前面に衝撃吸収部材が結合されている。【選択図】図2
