New description: 丨 101 years [New technical field] [0001] This creation is about a dual harmonic precision drive mechanism assembly, especially an efficient power kit for electric bicycles. [Prior Art] [0002] With the changes in the economy and society, the number of mass transit vehicles such as airplanes and steam locomotives has grown rapidly, and the demand for petroleum energy has also been relatively increased, resulting in an increase in international oil prices. Nowadays, crude oil has been over-quantified by mining. In addition, the carbon emissions are soaring, causing the global warming effect and thus seriously affecting the ecology. Therefore, the international community has issued warnings. In addition, the trend of Chinese people’s sports and fitness in recent years. The rise of bicycles that can save energy and reduce carbon and exercise has been a whirlwind in the past. It is not only a popular fashion leisure activity, but also a healthy and active lifestyle.

Therefore, once the user steps on the pedal on the electric bicycle, it will not be able to follow the rotation speed of the pedal. And there is a danger of causing accidental injury. Moreover, the gearbox used in the general industry can only convert the torque (torque) into a power of 6 Newtons per unit distance (meters). At this time, once the slope exceeds 15 degrees, it is used by the electric bicycle itself. The power of the output is not enough to climb. The user must exert a large amount of pedaling force to provide a large torque to climb the electric bicycle. In practice, there are deficiencies. Therefore, the author of this creation thinks about it. Designed a dual harmonic precision drive® mechanism assembly to improve the lack of existing technology and enhance the implementation of the industry. [New content] [0005] In view of the above shortcomings of the prior art, this creative department Design a dual harmonic precision drive mechanism assembly with patent elements such as novelty, advancement and industrial utilization, in order to overcome the difficulties of the prior art.
