Abstract

一种电动自行车的驱动机构包括一脚踏传动装置（4）、至少一前链轮（3）、一马达传动装置（2）、一第一单向传动装置（5）以及一第二单向传动装置（6）。脚踏传动装置（4）包括一脚踏转轴（41）。马达传动装置（2）装设在脚踏传动装置（4），并包括一定子（22）及转子（23），定子（22）或转子（23）具有一中空部（H）。马达传动装置（2）经由第一单向传动装置（5）与前链轮（3）耦接。第二单向传动装置（6）设置在中空部（H），脚踏转轴（41）经由第二单向传动装置（6）与前链轮（3）耦接，并且第二单向传动装置（6）在与脚踏转轴（41）垂直的一方向上不与第一单向传动装置（5）重迭设置。本发明的电动自行車的驱动机构通过两个单向传动装置，使得当马达传动装置（2）经由第一单向传动装置（5）驱动前链轮（3）转动时，脚踏转轴（41）不作动，进而方便使用者骑乘；并且当脚踏转轴（41）经由第二单向传动装置（6）驱动前链轮（3）转动时，马达传动装置（2）的定子（22）与转子（23）不作动，因而使用者不需额外花费力气来克服马达的作用力而达到省力功效。
