Abstract

The invention discloses an intelligent power assisting device of an electric bicycle, which comprises a moment center shaft, a controller and a brushless DC motor controlled by the controller. The moment center shaft comprises a moment shaft, a moment box body, a first optoelectronic switch, a second optoelectronic switch, a fixed anti-dazzling screen, a movable anti-dazzling screen, a chain support, a pressure spring support and a pressure spring, wherein the moment shaft is installed in the moment box body; the pressure spring support and the fixed anti-dazzling screen are fixedly installed on the moment shaft; the chain support is connected with the movable anti-dazzling screen; the pressure spring for driving the chain support is installed on the pressure spring support; the first optoelectronic switch and the second optoelectronic switch are fixed on the moment box body; the fixed anti-dazzling screen is embedded in a slot of the second optoelectronic switch, and the movable anti-dazzling screen is embedded in a slot of the first optoelectronic switch; and output ends of the first optoelectronic switch and the second optoelectronic switch are connected with a single-chip microcomputer input end of the controller.

Description

technical field [0001] The invention relates to an electric bicycle component, in particular to an electric bicycle intelligent booster. Background technique [0002] The DC brushless motor is used as the power device of the electric vehicle, and its ordinary pedal assist device is a magnetic ring Hall assist device. When pedaling, the central shaft drives the magnetic ring to rotate, and the Hall sensor senses the change of the magnetic field and outputs a square wave signal. The single-chip microcomputer detects the change of the signal and outputs PMW, and the controller power tube outputs voltage V and current I to provide to the brushless motor to make the motor run at full speed. [0003] The disadvantage of this power booster is that as long as the Hall senses a change in the magnetic field, the controller will turn the motor at full speed. The PMW output of the single chip microcomputer will not be changed according to the magnitude of the external force and the cha...
