Problems solved by technology

[0004] However, there are still some shortcomings in the above-mentioned sensing mode. In terms of sensing the rotational speed of the driving gear, when the user does not apply any pedal force, the driving gear will still continue to rotate. When stepping on the bicycle, the system will not immediately stop supplying the

Abstract

The invention provides a pedal force sensing system of a motorized bicycle. The pedal force sensing system is arranged in a motorized bicycle. The bicycle comprises a bicycle body, at least one shock absorber, a battery, a drive motor and a pedal drive mechanism. The pedal drive mechanism is provided with a first pedal and a second pedal which bears the pedal force and drive a pedal shaft to turn. The pedal force sensing system comprises a pedal force sensing set with a plurality of sensors which are arranged on the first pedal of the pedal drive mechanism to sense the pedal force borne by the first pedal; a main controller which is electrically connected with the battery, the drive motor and the shock absorber and receives the pedal force sensing signal of the pedal force sensing set so as to further control the operation of the drive motor and the shock absorption travel of the shock absorber according to the pedal force sensing signal. The pedal force sensing system can increase safety of driving the motorized bicycle, and more accurately sense the pedal force.

Description

technical field [0001] The invention relates to an electric assist bicycle, in particular to a pedal force sensing system of the electric assist bicycle. Background technique [0002] Under the influence of rising oil prices, energy-saving vehicles have become the focus of the public. Among them, electric-powered electric bicycles have the advantages of no pollution and low energy consumption. Therefore, in recent years, whether electric bicycles are used Vehicles used for fitness, leisure or short-distance transportation have become more and more popular in the market. [0003] Generally speaking, electric assist bicycles determine the power supply of the motor according to the user's pedaling force and the assist ratio mode set by the system, so electric assist bicycles must be equipped with a pedaling force sensing system to sense the user's pedaling force In the known technology, the industry mainly installs various sensors on the drive gear or the rear wheel axle to se...
