Provided is a front frame structure for an electric vehicle, which protects a power control unit, a cab, and a battery compartment from an impact load during a head-on collision. A front frame structure for an electric vehicle is provided with: a pair of left and right front side frames disposed on both sides in the vehicle width direction of a motor chamber provided in the front of a vehicle body and extending in the front-rear direction of the vehicle body; an impact absorbing member disposed at the front end of each of the front side frames; a bumper that couples the left and right impact absorbing members; and a lower frame disposed at the lower portion of the motor chamber, both sides of the lower frame in the vehicle width direction being supported by each of the front side frames, the front side frames being disposed in the remaining space between the side walls of the motor chamber in the vehicle width direction and the side surfaces of the power control unit, and a frame-shaped rigid member being disposed in the remaining space at the front portion of the motor chamber. A front side frame is coupled to a rear surface of a frame-shaped rigid member, and an impact absorbing member is coupled to a front surface of the frame-shaped rigid member.

    本发明提供保护动力控制单元、驾驶室、蓄电池室免受正面冲撞时的冲击载荷的电动汽车用前框架构造。电动汽车用前框架构造具备:左右一对前侧框架,配设于在车体的前部所设置的马达室的车宽方向两侧,并在所述车体的前后方向上延伸;冲击吸收构件,配设于各前侧框架的前端;保险杠,将左右的冲击吸收构件结合;以及下框架,配设于马达室的下部,并且车宽方向两侧被各前侧框架支承,前侧框架配设于马达室的车宽方向侧壁与动力控制单元的侧面之间的剩余空间,在马达室的前部的剩余空间配设有框状刚性构件,前侧框架与框状刚性构件的后表面结合,冲击吸收构件与所述框状刚性构件的前表面结合。
