The invention discloses an electric power steering device, and the device comprises a motor, a controller and a shell. The controller comprises a control circuit board assembly and a driving circuit board assembly. The device further comprises a PCB, wherein the PCB is a flexible PCB or a semi-flexible PCB; the PCB is arranged in a laminated manner after being bent, and the PCB comprises an upper PCB, a middle PCB and a lower PCB. The device also comprises a first device unit which is mounted on the upper PCB to form the control circuit board assembly; and a second device unit which is mounted on the lower PCB to form the driving circuit board assembly. The control circuit board assembly and the driving circuit board assembly are arranged in a stacked mode, the circumferential size of the electric power assisting device can be effectively reduced, the structure is compact, and whole vehicle installation is convenient.

    本发明公开了一种电动助力转向装置,包括电机、控制器、壳体,所述控制器包括控制电路板组件、驱动电路板组件;该装置还包括:一个PCB板,该PCB板为柔性PCB板或半柔性PCB板;其中,所述PCB板折弯后层叠布置,所述PCB板包括上PCB板、中间PCB板及下PCB板;第一器件单元,安装在所述上PCB板上形成所述控制电路板组件;第二器件单元,安装在所述下PCB板上形成所述驱动电路板组件。本发明通过让控制电路板组件、驱动电路板组件层叠布置,能够有效降低电动助力装置的周向尺寸,且结构紧凑,方便整车安装。
