Abstract

The invention discloses an integrated hub motor of an electric bicycle. The integrated hub motor comprises a horizontally arranged spindle, a hub shell rotatably mounted outside the spindle, a motor core, a controller and batteries providing electric energy. A support arranged outside the motor core in a sleeving mode is fixed inside the hub shell, and the batteries and the controller are both mounted on the support. According to the integrated hub motor, the motor core, the batteries and the motor controller are all arranged in the hub shell, the structure compactness of the hub motor is greatly improved, and work stability and safety of the hub motor are improved.

Description

technical field [0001] The invention relates to an electric bicycle integrated wheel hub motor, which is suitable for electric bicycles, especially electric bicycles. Background technique [0002] An electric bicycle is a special bicycle that uses an electric system to manage and control the drive of the entire vehicle to realize human riding, electric or electric assist functions. It has the advantages of lightness, energy saving, and environmental protection, and has been welcomed by people and has become the main means of transportation with the fastest growth in recent years. Especially in the European market, the main requirements are portability and practicality. [0003] In the prior art, the battery, the motor controller and the motor core of the electric bicycle hub motor have a split structure, wherein the motor core is arranged in the hub shell, while the battery and the motor controller are installed on the frame. There are many external wiring in this structur...
