The invention provides an integrated electric power assist device for bicycles, which can solve the requirement that the separate electric power assist device of the existing electric power assist bicycle has a bulky structure and is not suitable for adding or refitting the electric power assist system of ordinary bicycles. The in-wheel motor assembly, the main control circuit board and the battery assembly are electrically controlled. The side cover is sealed, and the outer peripheral surface of the shell is connected to the rear wheel of the bicycle through spokes. The hub motor assembly is integrally assembled in the inner ring cavity of the circular battery assembly. The left and right axial ends of the hub motor assembly are respectively The left support shaft and the right support shaft are connected to the rear wheel bracket of the bicycle. A flywheel is installed on the axially extending end of the right support shaft. Two Hall sensors are mounted on the flywheel. control connection, and the flywheel is connected with the bicycle chain through transmission.
Description
technical field [0001] The invention relates to the field of electric assist bicycles, in particular to an integrated electric assist device for bicycles. Background technique [0002] With the growing economy, the travel demand of urban residents continues to increase. At the same time, cars have been criticized for occupying a lot of road resources and causing pollution. People began to look for travel tools that are more suitable for cities. In Germany, the Netherlands, Japan and other countries, electric bicycles have become a new trend in urban travel due to their fast, convenient and labor-saving experience. The intelligent power system equipped with electric bicycles can read the riding intention, automatically judge the road conditions, and provide users with auxiliary power in real time. More and more consumers are beginning to consider new travel tools. They value travel efficiency, pay attention to aesthetic taste, and pursue green environmental protection. At p...
