The invention belongs to the field of motors, and particularly relates to an epicycloid bicycle centrally-arranged power device. The epicycloid bicycle centrally-arranged power device comprises cranks(10) and an outer rotor structure motor (1), wherein the cranks (10) rotate to drive a chain wheel (9) to rotate; the outer rotor structure motor (1) is arranged between the two cranks (10); when theouter rotor structure motor (1) outputs, the chain wheel can be controlled to move; and when the outer rotor structure motor (1) has no output and the cranks (10) rotate, a second one-way ratchet wheel (12) is driven to compress a spring (13) distributed at the top of a shaft sleeve (8) at the same time, the spring (13) is compressed to intermittently drive the shaft sleeve, and therefore the chain wheel (9) arranged on the shaft sleeve is driven to rotate. Output of three modes of direct pedal crank rotation, outer rotor structure motor rotation and servo motion jointly controlled by a torque sensor output part is achieved, torque sensing can be achieved, a riding strength requirement is reflected more accurately, and riding comfort is improved through synchronous motor servo control output.

    本发明属于电机领域,具体涉及一种外摆线自行车中置动力装置,其特征在于:曲柄(10),曲柄(10)转动能够带动牙盘(9)转动;外转子结构电机(1),外转子结构电机(1)设置在两个曲柄(10)之间;当外转子结构电机(1)输出时能够控制牙盘运动;当外转子结构电机(1)没有输出,曲柄(10)旋转时,第二单向棘轮(12)被带动,同时压缩分布在轴套(8)顶部的弹簧(13),压缩弹簧(13)间歇带动轴套,从而带动设置在轴套的牙盘(9)旋转运动。本发明直接脚踏曲柄旋转、外转子结构电机旋转、扭力传感器输出部共同控制伺服运动三种方式输出,能够扭力传感,更准确反应骑行力度需求,同步的电机伺服控制输出增加骑行舒适度。
