Description

Technical Field

[0001] The present invention relates to the technical field of power-assisted bicycles, and in particular to a smart phone interconnection system based on an IOT power-assisted bicycle. Background Art

[0002] Bicycles are a common means of transportation, which are light, cheap, and environmentally friendly, and are therefore popular among the public. However, a major disadvantage of bicycles is that they are very laborious to ride on hills or carry heavy objects, because the torque required to climb a hill is very large, which brings inconvenience to the user. In order to meet the needs of riding on multiple road conditions, power-assisted bicycles with transmissions are designed in the prior art.

[0003] Power-assisted bicycle is a new type of two-wheeled vehicle, a type of bicycle, which uses battery as auxiliary power source, is equipped with a motor, and has a power assistance system. It is a new type of transportation tool that can realize the integration of human riding and motor assistance. With the development of related technologies of power-assisted bicycle power systems, technologies including motors, motor controllers, sensor modules, instruments, batteries, etc. are developing rapidly.

[0004] In the field of power-assisted bicycles, there are two main types of motor installation positions. One is the mid-mounted motor, which is installed in the middle of the vehicle body, that is, the motor at the bottom bracket position. The mid-mounted motor is connected to the frame and connected to the rear wheel through a chain or other transmission mechanism to transmit power. At the same time, pedals are installed on both sides of the motor. When the motor has no power supply, the rider can use the pedals to achieve human riding, and the resistance is not significantly different from that of a normal bicycle.
