For a further understanding of the structural features of the present invention, the application of the technical means, and the intended effect, the manner of use of the present invention will be described. It is believed that the invention can be more deeply and specifically understood as follows: Referring to the first to the tenth, when the user turns off the assisting and resistance control device 100, the controller 31 controls the motor unit 20 to enter the clutch state, and the control mode is as shown in the second figure. The electromagnet 24 is reversely energized, so that the battery iron 24 is reversely excited to push away from the inner wheel 211, and the second magnet 25 is magnetically attracted by the fixed magnet 26, and the inner wheel 211 is linked to the inner magnet 211. The fixed magnet 26 moves in the direction, so that the inner wheel 211 is separated from the outer wheel 212, and the rotor 28 is offset from the stator 27, and the rim 203 can be disengaged from the motor unit 20 to lower the rim 203. Resistance to rotation.

When the user activates the assisting and resistance control device 100, the controller 31 at this time When the motor unit 20 is driven to bring the inner wheel 211 and the outer wheel 212 to a rotational speed, the electromagnet 24 is energized as shown in the third figure, and the electromagnet 24 is energized to attract the first magnet 23, and The magnetic attraction between the electromagnet 24 and the first magnet 23 is greater than the magnetic attraction between the fixed magnet 26 and the second magnet 25, and the inner wheel 211 is moved away from the stator 27 to allow the inner wheel 211 to The outer wheel 212 is coupled, and the rotor 28 is located at the position corresponding to the stator 27, and the rim 203 is engaged with the motor unit 20. Thereafter, the controller 31 automatically determines to enter the power generation mode according to the values of the sensors. Or the power generation mode is controlled as follows: when the controller 31 detects that one of the conditions of low power, fast speed or falling slope occurs or occurs simultaneously, the controller 31 enters the power generation mode. The rim 203 can drive the outer wheel 212 to rotate the inner wheel 211, so that the rotor 28 can rotate around the stator 27, and the stator 27 generates induction power and charges the battery unit 10, so that the motor unit 20 Enter the power generation state .

When the controller 31 detects that one of the conditions of sufficient power, slow vehicle speed, rising slope, and the speed of the pedal 204 is greater than the predetermined value occurs or occurs simultaneously, the controller 31 converts the power generation mode into The assist generating mode, and controlling the battery unit 10 to provide power to the stator 27, causing the stator 27 to generate a magnetic force to drive the rotor 28, thereby interlocking the inner wheel 211 to drive the outer wheel 212 to rotate, and the rim 203 can be driven to rotate.

The displacement value of 356 further causes the resistance adjuster 12 to adjust the charging current for charging the battery unit 10 by the motor unit 20, so that the running resistance of the motor unit 20 is changed, so as to interlock the rim 203 to generate a magnetic braking effect, and enter Deceleration state.
