The invention provides a pedal type driving mechanism which has four implementation forms, when a bicycle is taken as an example, a center shaft is taken as a circle center, the inner sides of crank arms at the two ends of the center shaft are each provided with an eccentric wheel, and the eccentric wheels are fixedly connected with the crank arms through screws so that the eccentric wheels and the crank arms can rotate around the center shaft together; an outer ring is arranged on the periphery of each eccentric wheel, a rolling part is arranged between each eccentric wheel and each outer ring, each outer ring is connected with an external rack or an external chain, the rack or the chain is meshed with the outer circle of a flywheel, the eccentric wheels enable the rack or the chain to reciprocate through pedal rotation, and reciprocating motion of the rack or the chain drives the flywheel and a wheel to rotate; the eccentric wheels can be provided with inner ring grooves, a small bearing is arranged in each inner ring groove, each small bearing is fixed to one side of the front end of the rack through a shaft, and rotation of the eccentric wheels enables the small bearings to move in the inner ring grooves along the inner ring grooves, enables the rack to do reciprocating motion and drives wheels. When the driving mechanism is used, a user can feel smooth and labor-saving; the bicycle can also be pedaled backwards, and the bicycle can still walk forwards when pedaled backwards. The pedal type driving mechanism is simple in structure and easy to produce and manufacture, and can become an updating product of pedal type driving mechanisms such as bicycles and tricycles.

    本发明脚踏式驱动机构有四种实现形式,以自行车为例时以其中轴为圆心,在中轴两端拐臂的内侧各装一个偏心轮,偏心轮通过螺钉与拐臂连接固定,使之能够与拐臂一同绕中轴旋转,在偏心轮的外围有外圈,在偏心轮与外圈之间有“滚动部件”,外圈外连接齿条或链条,齿条或链条与飞轮外圆啮合,偏心轮通过脚踏旋转使齿条或者链条往复运动,齿条或者链条的往复运动带动飞轮及车轮旋转;偏心轮可以是带内环槽的,在内环槽内设置小轴承,小轴承通过轴固定在齿条前端一侧,该偏心轮的旋转致使小轴承在内环槽内沿内环槽运动并使齿条产生往复运动并驱动车轮;使用该驱动机构会感到“顺滑”和“省力”;它还可以向后蹬,其向后蹬仍然能够向前行走;它结构简单易于生产制造,将成为自行车、三轮车等脚踏式驱动机构的换代产品。
