A steering column type electric power assisting device comprises a shell, wherein a hollow inner rotor brushless motor is installed in the shell, a coil stator of the hollow inner rotor brushless motor is connected with the inner wall of the shell, a shaft sleeve is arranged at the center of a magnetic steel rotor of the hollow inner rotor brushless motor, and an intermediate shaft is installed in the shaft sleeve and fixedly connected with the shaft sleeve; an upper cover is installed on the shell, located at one end of the intermediate shaft and connected with a steering shaft of a vehicle steering column, a torsion rod and a torque angle sensor are installed between the steering shaft and the intermediate shaft, one end of the torsion rod is fixedly connected with the steering shaft, and the other end of the torsion rod is fixedly connected with the intermediate shaft. The device is small in occupied space, interference with peripheral parts is avoided, dismounting and mounting are easy, and the torque of the motor is amplified through a planetary gear reducer. Compared with existing electric power assisting devices, the electric power assisting device has the advantages that mechanical transmission efficiency is improved greatly, and vehicle steering can be conducted more flexibly and easily with higher stability.
