The invention discloses a method for overcoming a power generation dead point of a bicycle. A pedal device is mounted on the bicycle; the pedal device comprises a right crank, a left crank, a right pedal, a left pedal, a right half shaft, a left half shaft, a chain wheel, a driving first-order non-circular gear, a driven first-order non-circular gear, a driving circular gear, a driven circular gear and a through shaft; a driving structure of an existing bicycle is improved, a chain wheel is still used for driving a chain, a pair of first-order non-circular gears is installed in the driving structure, and rotating shafts of the first-order non-circular gears are arranged to deviate from the centers of the gears. The pedal plate on the other side is located at the 1 o'clock position in the clockwise direction, the force exerting positions of the pedal plates on the two sides perfectly avoid force exerting dead points of 12-1 o'clock positions, the positions of the force exerting points are located at the 1 o'clock position to the 6 o'clock position all the time, and therefore force exerting is reduced, and driving efficiency is improved.

    一种克服自行车发力死点的方法,是在自行车上安装脚踏装置;所述脚踏装置包括右侧曲柄、左侧曲柄、右踏板、左踏板、右半轴、左半轴、牙盘、主动一阶非圆齿轮、被动一阶非圆齿轮、主动圆齿轮、被动圆齿轮、通轴;本发明是对现有自行车的驱动结构进行改进,依然使用牙盘驱动链条,在驱动结构中安装一副一阶非圆齿轮,所述一阶非圆齿轮的转动轴偏离齿轮的中心设置,骑行时当一侧的脚踏板到达下端6点位时,另一侧的脚踏板位于顺时针方向的1点位,两侧脚踏板的发力位置完美避开了12‑1点位的发力死点,发力点的位置始终在1点位‑6点位,因此减少了无用力,提高了驱动效率。
