Provided is a front frame structure for an electric vehicle, capable of effectively protecting a power control unit, an operation cabin, and a battery compartment from an impact load during a head-on collision. A front side frame is disposed in a remaining space formed between a side wall of a motor chamber and a side surface of a power control unit, the front side frame having a rear wall upper portion and a front arm-shaped portion, a first inclined surface portion having a predetermined elevation angle formed at a lower portion of the wall-shaped portion from the rear portion toward the front, and a second inclined surface portion having a predetermined elevation angle formed at a lower portion of the arm-shaped portion from the rear portion toward the front portion. A second inclined surface portion having a predetermined depression angle is formed forward from an end portion of the first inclined surface portion to join the front side frame and the lower side frame provided on the left and right sides of the lower frame, and the front reinforcement reinforces the combination of the front side frame and the front end portion of the lower side frame. The side surface of the upper valley line portion where the two inclined surface portions are joined and the side surface of the lower frame opposite to the lower portion of the upper valley line portion are connected by a rear reinforcing member.
提供一种电动汽车用前框架构造,能够有效地保护动力控制单元、驾驶舱和蓄电池室免受正面碰撞时的冲击载荷。将前侧框架配设在马达室的侧壁与动力控制单元的侧面之间形成的剩余空间,所述前侧框架具有后部的壁上部和前部的臂状部,在壁状部的下部从后部朝向前方形成有预定仰角的第一斜面部,在臂状部的下部,从第一斜面部的端部朝向前方形成有预定俯角的第二斜面部,将前侧框架和设置于下框架的左右的下侧框架接合,利用前增强件将前侧框架与下侧框架的前端部的结合加强,利用后增强件将两斜面部接合的上侧谷线部的侧面和与上侧谷线部的下方相对的下侧框架的侧面连结。
