Abstract

The invention provides an operation method of an electric aided-bicycle. The method includes the following steps that pedaling force applied by a driver is received, and torque is transmitted to a flywheel through a chain wheel of the bicycle by means of a force transmission mechanism; a supporting mechanism bears the force applied on the supporting mechanism by the force transmission mechanism in the torque transmission process; a recovery mechanism stores force and is deformed when the supporting mechanism is stressed, and the recovery mechanism enables the supporting mechanism to recover to the initial state after the pedaling force is relieved; an assisted motor makes a response when the force borne by the supporting mechanism reaches the preset condition and outputs electric force assisting the pedaling force based on the force and / or changes of force, and the electric force is not output when the force does not reach the preset condition.

Description

technical field [0001] The present invention relates to an electric assist bicycle provided with an electric motor for assisting a driving force based on a pedaling force generated by a person pedaling a bicycle pedal, thereby reducing the burden on the rider, especially when going uphill. Background technique [0002] There are known electric assisted bicycles, that is, a power storage device such as a battery and a motor powered by the power storage device are used to detect the pedaling force provided by the driver to the sprocket through the pedals. Assisting the provision of electric driving force makes it possible to travel easily even when going uphill or the like. The detection of pedal force is the key point of this type of electric moped. [0003] The existing method in the prior art is to use a torque sensor, which is assembled on the bearing between the two cranks to sense the torque of the crankshaft, and the motor outputs the assist torque according to the inf...
