Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention.
As shown in fig. 1 and 2, in a bicycle brake assist device, comprising a controller 1, a connecting wire 4, a permanent magnet motor 2 and a resistor 3, wherein the permanent magnet motor and the resistor are arranged on a wheel, and the permanent magnet motor is connected with the resistor through the connecting wire; the controller is a multi-gear switch, is arranged on the handle bar of the bicycle 5, and is connected with the joint of the resistor through a lead; the controller can be a multi-gear switch with various models, and does not have specific model requirements; the resistor can adopt any suitable resistor element with any structure; the permanent magnet motor can be a direct current permanent magnet motor with a commutator, and is also suitable for an alternating current permanent magnet motor without a commutator; the connecting lead is a common wire.
When the bicycle is braked, the resistance value of the resistor connected with the permanent magnet motor is changed by controlling the multi-gear switch, so that the load of the permanent magnet motor is changed, the braking force generated by the permanent magnet motor is controlled, and the strength of the braking force of the bicycle is selectively controlled.
When braking, the permanent magnet motor on the wheel is utilized, according to the energy consumption braking principle, the wheel rotates to drive the permanent magnet generator to rotate, so that electric energy is generated, and the process is to convert the mechanical energy of the vehicle into the electric energy. Since the permanent magnet generator and the resistor are connected by wires, this electrical energy consumption is converted into thermal energy at the braking resistor. The method consumes the energy of the kinetic energy of the vehicle, generates braking force and completes the braking operation of the bicycle.
