Wind power generating device of transportation vehicle

A wind power generating device, comprising:

• a power source assembly which includes a rotor component and a brake component, the rotor component including a blade and a drive shaft, the blade being served to receive the wind force from the front side to rotate, the drive shaft being in driven connection with the blade to transfer the rotary motion of the blade, the brake component including a brake disc and a brake actuator, the brake disc being positioned at the back side of the blade and being configured to interlink with the blade so as to rotate together with the blade, the brake actuator being configured to swing around a lever fulcrum, and the brake actuator being configured with a wind collector on one side with respect to the lever fulcrum to receive the wind force from the front side and a brake pad corresponding to the brake disc on the other side with respect to the lever fulcrum such that when the wind collector swings backward with the pushing of the wind force from the front side, the brake pad relatively swings frontward to touch the brake disc by means of the leverage of the brake actuator so as to apply a brake force in such a manner that the rotor component is braked;
• and
• a power generating assembly, which includes a power generating element, a maximum power point tracker (MPPT) and an energy storage element which are electrically connected to each other, the power generating element being in drive connection with the drive shaft such that the power generating element is driven by the drive shaft to generate electric energy, and the generated electric energy is stored to the energy storage element under the control of the maximum power point tracker.
