Abstract: A magnetic brake system includes a magnetic induction unit, which is fixedly mounted at the chassis of a vehicle and comprising a stack of silicon steel sheets and a coil wound round the stack of silicon steel sheets and electrically connected to a switch at a brake pedal of the vehicle, and a magnetic attraction unit, which is arranged corresponding to the magnetic induction unit for causing a magnetic attractive or repulsive force between the magnetic induction unit and the magnetic attraction unit when the brake pedal is pressed to switch on the switch.

Abstract: A power regulating circuit assembly includes a circuit board electrically connected to the car battery, a capacitor set, a power transistor electrically coupled to the capacitor set for controlling the capacitor set to discharge accumulated electric current automatically, a solenoid switch electrically coupled to the capacitor set for controlling the capacitor set to discharge accumulated electric current manually, and an IC electrically coupled to the power transistor and the solenoid switch for auto/manual control.
