The present invention relates to a front impact absorbing frame for an electric vehicle and more particularly, to a front impact absorbing frame for an electric vehicle that effectively distributes and absorbs a front impact force with a deformation-inducing member. The front impact absorbing frame for absorbing a front impact on an electric vehicle comprises: a bumper beam; a first transverse beam connected to a rear end of the bumper beam and arranged in a vehicle width direction; a second transverse beam arranged at a rear end of the first transverse beam; a first vertical beam connecting the bumper beam and the first transverse beam; a second vertical beam connecting the first transverse beam and the second transverse beam; and a first deformation-inducing unit and a second deformation-inducing unit provided on the first vertical beam and the second vertical beam, respectively. The front impact absorbing frame overcomes the structural limitations of small electric vehicles and much better absorbs front impact, thereby protecting occupants in a boarding space against shock from a frontal collision. 본 발명은 전기자동차 전방충격 흡수프레임에 관한 것으로서 보다 상세하게는, 변형유도부재를 마련하여 전방의 충격력을 효과적으로 분산흡수 시키는 전기자동차 전방충격 흡수프레임에 관한 것으로서, 전기자동차의 전방충돌 충격을 흡수하는 전방충격 흡수프레임에 있어서, 범퍼빔; 상기 범퍼빔의 후단에 연결되어 차폭 방향으로 배치된 제1 가로빔; 상기 제1 가로빔의 후단에 배치된 제2 가로빔; 상기 범퍼빔과 상기 제1 가로빔을 연결하는 제1 세로빔; 상기 제1 가로빔과 상기 제2 가로빔을 연결하는 제2 세로빔; 상기 제1 세로빔 및 제2 세로빔에는 각각 제 1변형유도부 및 제2 변형유도부; 가 포함된 것을 특징으로 하는 전기자동차 전방충격 흡수프레임을 제공하여, 소형전기자동차의 구조적 한계를 뛰어 넘어서 전방 충격을 보다 잘 흡수함으로써 탑승공간의 탑승자를 전방충돌의 충격으로부터 보호할 수 있는 강점이 발휘된다.
