electric booster

Abstract

The invention discloses an electric power assisting device. The electric power assisting device comprises a flywheel, a wireless intelligent torque sensor module, a shell A, a shell B, a hollow middle shaft, a center supporting frame and an assisting-power module, wherein the assisting-power module comprises an assisting-power generation component, an assisting-power delivery component, a torque sensor and an intelligent controller, the shell A is connected with the hollow middle shaft through a bearing, the shell B is configured in a rotatable mode, the flywheel penetrates through the shell A to be connected with the wireless intelligent torque sensor module through a bolt, the wireless intelligent torque sensor module is installed on the inner surface of the shell A, torque is transmitted to the intelligent controller through the torque sensor, the assisting-power generation component is controlled by the intelligent controller to generate the needed assisting-power, and the needed assisting-power is delivered to the shell B through the assisting-power delivery component. According to the electric power assisting device, the feeling of a rider is optimized, the rider can adjust according to self physical power to ride farther freely, and not only is the destination reached quickly, but also proper exercise can be conducted according to self conditions.

Description

technical field [0001] The present invention relates to an integrated integrated electric power booster, in particular to an integrated lithium battery, motor, motor reducer, motor driver, intelligent controller, torque sensor, etc. applied to the rear wheel of a bicycle to detect The riding torque is the input, and the motor assist torque is the output. It can observe the data and control it through the Bluetooth device. It is an integrated all-in-one electric power assist device. Background technique [0002] In 2014, the total sales volume of bicycles and electric bicycles in China was close to 40 million, and the market is huge. With the development of society, large and medium-sized cities are facing more and more serious traffic congestion problems, and the convenience and flexibility brought by bicycles and electric bicycles have once again become the focus of attention. [0003] There are many problems in current electric bicycles. For example, the vast majority of ...

AI Technical Summary

Problems solved by technology

[0003] There are many problems in current electric bicycles. For example, most electric bicycles use lead-acid batteries, which have low energy density. In order to achieve a certain mileage, dozens of kilograms of lead-acid batteries are often needed.

Not only does it cause problems such as heavy weight of electric bicycles, difficulty in handling, and difficulty in charging, but also the cycle life of lead-acid batteries is low, and needs to be replaced in about 1 to 2 years, which wastes resources and easily pollutes the environment

In addition, in the current electric bicycles, the motor, motor driver, battery and other components are separated and scattered in various parts of the electric bicycle. The parts are connected by wires exposed to the environment, which is not conducive to the safety and durability of the whole vehicle sex, and the exposed wires spoil the aesthetics of the vehicle
