Power refitting kit for lightweight bicycle and refitting control method of lightweight bicycle

Abstract

The invention discloses a power refitting kit for a lightweight bicycle and a refitting control method of the lightweight bicycle. The power refitting kit for the lightweight bicycle comprises a crossbeam part, a handlebar part and a wheel part; the crossbeam part comprises mounting packages, batteries and a controller which are carried on a bicycle crossbeam; and the controller comprises a single chip microcomputer and a brushless motor driving plate. The handlebar part comprises brake power-off switches and control buttons mounted on bicycle handlebars through silicone straps. The wheel part comprises a brushless motor, a speed-measuring magnet and a speed-measuring Hall sensor. The controller is connected with the batteries, the control buttons, the brushless motor, the brake power-off switches, the speed-measuring magnet and the speed-measuring Hall sensor to form a control system. According to the power refitting kit for the lightweight bicycle and the refitting control method of the lightweight bicycle, improvement is conducted based on an original bicycle to enable the lightweight bicycle to have the power-driven function replacing manpower, control of different modes including the constant-speed mode, the power mode and the power-assisted mode is achieved, and riding and controlling are convenient.

Description

Technical field [0001] The invention relates to the field of bicycle modification, in particular to a lightweight bicycle power modification kit and a modification control method thereof. Background technique [0002] With high oil prices and increased environmental awareness, bicycles are still an important means of transportation in today's society due to their light and flexible characteristics. Due to the gradual expansion of the scale of cities and the gradual increase in the scope of people's activities, traditional bicycles are difficult to meet this change, so electric bicycles have a huge market. However, the traditional lead-acid battery car is very heavy and difficult to charge, so it is not suitable for large-scale cities with high-rise buildings. The price of lithium battery electric vehicles is high, and the appearance type is relatively single, which is difficult to meet people's demand for cost performance and appearance. Some electric vehicle modification kits ...

AI Technical Summary

Problems solved by technology

However, the current bicycle refitting process is complicated, requiring dismantling of the handlebars, center shaft, rear wheel, and transmission system, requiring users to have extremely high hands-on skills, so it is difficult to popularize

In addition, the energy density of the battery is small, and the long-distance battery life inevitably requires a large volume. The large battery seriously affects the appearance of the vehicle and is not easy to carry and replace.
