PROBLEM TO BE SOLVED: To reduce a cost for manufacturing an electric assist device.SOLUTION: A drive device has (A) a drive portion which drives an electric motor for assisting man power, (B) a power storage device, (C) a control portion which controls the drive of the electric motor by the drive portion and KAISEI from the electric motor, and charging/discharging to/from the power storage device, and (D) a sheath for storing the drive portion, the power storage device, and the control portion together. The drive portion may include a switch performing voltage conversion of electric power supplied from the power storage device to the electric motor. (E) The drive device may further have a second connecting portion which is used for charging to the power storage device and is different from a first connecting portion for connecting to the electric motor, and (F) a circuit which is connected to the second connecting portion and the switch, and converts voltage applied on the second connecting portion into voltage for charging to the power storage device.SELECTED DRAWING: Figure 3
【課題】電動アシスト装置製造のコストを削減する。【解決手段】本駆動装置は、(A)人力を補助するための電動機を駆動する駆動部と、(B)蓄電デバイスと、(C)駆動部による電動機の駆動及び電動機からの回生と蓄電デバイスに対する充放電とを制御する制御部と、(D)駆動部と蓄電デバイスと制御部とを1つに収める外装とを有する。上で述べた駆動部は、蓄電デバイスから供給される電力の電圧変換を電動機に対して行うためのスイッチを含むようにしても良い。そして、(E)上で述べた駆動装置は、蓄電デバイスに対する充電に用いられ且つ電動機との接続用の第1の接続部とは異なる第2の接続部と、(F)第2の接続部とスイッチとに接続されており、第2の接続部に印加された電圧を蓄電デバイスに対する充電のための電圧に変換するための回路とをさらに有するようにしても良い。【選択図】図3
