Abstract
A power module of an electric assisted bicycle is disclosed and includes a pedal shaft, a housing, a motor, a reducer and a gear-plate output shaft and a sensing component. The housing includes a partition portion extended along a radial direction to divide an inner space of the housing into a motor accommodation portion and a reducer accommodation portion for accommodating the motor and the reducer, respectively. A stator of the motor and a fixed gear are respectively fixed to a first side and a second side, which are two opposite sides of the partition portion. A reducer input shaft includes two ends connected to the motor and the reducer, respectively, and an input-shaft main part disposed therebetween is connected to a third side of the partition portion. With the connection configuration of the three sides of the partition portion, the space utilization of the entire power module is optimized.
