The invention discloses a folding elastic pedal plate and a power conversion system of a new national standard electric bicycle, the three sides of the pedal plate are wrapped with elastic materials, and various folding structures are arranged on a crank, so that the plane of the pedal plate can rotate into the rotating plane of the crank, or is stored in a bicycle body or on the lower surface of the bicycle body; or the folding pedal is provided with a locking mechanism which is used for locking the crank position of the folding pedal. The power conversion system is characterized in that a rear wheel hub is parallel to the direct-drive motor or sleeved outside the direct-drive motor, a one-way clutch is arranged between a chain wheel driven by the pedal and the rear wheel hub, and a one-way clutch is arranged between a rotor output shaft of the direct-drive motor and the rear wheel hub; or a gear shifting mechanism is arranged on the middle axle and the axle of the rear wheel, the gear shifting mechanism is provided with at least two gears, and the folding pedal, the gear shifting mechanism and the one-way clutch have various matched use schemes. The pedals and the cranks of the electric bicycle can be folded, legs are not prone to being impacted, and pedal riding is more convenient.

    本发明公开了新国标电动自行车的折叠弹性脚踏板和动力转换系统,所述脚踏板的三边包裹弹性材料,且曲柄上设有各类折叠结构,使得脚踏板的平面可以转动至曲柄旋转平面内,或收藏在车身内部或车身下表面;所述折叠脚踏板或具有锁定机构,锁定所述折叠脚踏板的曲柄位置。动力转换系统的特征是后轮轮毂与直驱电机平行或套设于其外部,脚踏板驱动的链轮与后轮轮毂之间、直驱电机的转子输出轴与后轮轮毂之间各具有一个单向离合器;或在中轴、后轮轮轴具有换挡机构,换挡机构具有只少二个档位,折叠脚踏板和换挡机构、单向离合器具有多种配合使用的方案。本发明使得电动自行车脚踏板和曲柄可以折叠,不易撞击腿部,脚踏骑行更轻便。
