By a News Reporter-Staff News Editor at Politics & Government Week -- According to news reporting originating from Washington, D.C., by VerticalNews journalists, a patent application by the inventors LEE, Shou-Hsun (Tainan, TW); LI, Chun-I (Tainan, TW), filed on May 16, 2018, was made available online on November 22, 2018.

No assignee for this patent application has been made.

Reporters obtained the following quote from the background information supplied by the inventors: "For the demand of electricity, some vehicles are equipped with conventional power generating devices, such as solar panels or wind power generating devices thereon. The solar panels on the vehicles are unable to generate electricity during cloudy or rainy days. Similarly, when a vehicle equipped with the conventional wind power generating device is stopped, a fan blade of the wind power generating device is stopped accordingly and unable to generate electricity due to the lack of wind force.

"However, there is still a need for electricity even when vehicles are stopped for a moment such as waiting for the red light. In other words, the conventional wind power generating device is not suitable for the condition in practice of the vehicle. Thereby, it is necessary to propose a wind power generating device suitable for the transportation vehicles."

In addition to obtaining background information on this patent application, VerticalNews editors also obtained the inventors' summary information for this patent application: "Therefore, an objective of the present invention is to provide a wind power generating device installed in a vehicle capable of maintaining a time period of electricity generation even when wind speed is low or none due to vehicle stop

"In order to solve the abovementioned problem, the present invention provides a wind power generating device installed in a vehicle, comprising: a fan blade being rotated when receiving a wind force; a rotating device including a rotating disk, a plurality of magnetic elements, a plurality of ball chambers, and a plurality of balls, the rotating disk having a shaft connecting portion, the shaft connecting portion being coaxial with the rotating disk, the rotating disk kinetically connected to the fan blade through the shaft connecting portion to enable the rotating disk to rotate with the fan blade coaxially, the plurality of magnetic elements being annularly arranged at a periphery area of the rotating disk respectively, each magnetic element being allocated in a magnetic moment direction that shifts with a deviating angle from a radial direction of the rotating disk, the plurality of ball chambers being annularly arranged by surrounding the shaft connecting portion, each ball chamber extending outward from an outer wall of the shaft connecting portion, each ball chamber being formed with two side walls, each side wall being allocated as being shifted with a wall shifting angle from the radial direction of the rotating disk, and each ball chamber being provided with at least one ball; a securing ring neighbored and surrounding the rotating disk, the securing ring including a plurality of corresponding magnetic elements, each corresponding magnetic element being configured as annularly arranging in inner peripheral of the securing ring and facing the rotating disk in such a manner that the corresponding magnetic element is with magnetic repulsion to the magnetic element such that a magnetic repelling force between the magnetic elements and the corresponding magnetic elements is generated; and a power generating device having a power input shaft, the power input shaft being kinetically connected to the shaft connecting portion so as to rotate with the rotating disk.

"In one embodiment of the present invention, each ball chamber is provided with one ball.

"In one embodiment of the present invention, the deviating angle is 45 degree.

"In one embodiment of the present invention, the wall shifting angle is 45 degree.

"In one embodiment of the present invention, each magnetic element and each corresponding magnetic element face each other with the same magnetic polarity.

"In one embodiment of the present invention, the fan blade includes a center shaft and a plurality of blades. The center shaft includes a shaft body and a cone portion projecting forward and tapering from the shaft body. The plurality of blades are allocated as surrounding the shaft body, and an apex angle of the cone portion is less than 30 degree.

"In one embodiment of the present invention, each blade includes a front edge, a rear edge and an inner edge. The inner edge is connected between the front edge and the rear edge. A front end of the inner edge is connected to a front portion of the shaft body while a rear end of the inner edge is connected to the rear portion of the shaft body. A middle end is a middle portion of the inner edge located between the front end and the rear end. The middle end is in a U-shape and extends outward along the radial direction of the shaft body such that a wind-guiding hole is formed between the inner edge and the shaft body in such a manner that the blade is formed as a three-dimensional U-shape bending from front side to rear side.

"In one embodiment of the present invention, each blade includes a front edge and a rear edge. Further, an outer edge portion of the front edge and an outer edge portion of the rear edge are in curve shape.

"In one embodiment of the present invention, a curving degree of each curve-shaped rear edge is larger than a curving degree of each curve-shaped front edge.

"By the technical means adopted by the wind power generating device of the present invention, the power generator is driven by a combination of the fan blade and the rotating disk providing with the magnets and the balls. When a vehicle is moving forward, the rotating disk is rotated by the driving force of the fan blade to enable the power generating device to generate electricity. A kinetic assisting device formed by a rotating device and a securing ring achieves an object of a smoother rotating movement for the power input shaft of the power generating device such that the wind power generating device is capable of maintaining a time period of electricity generation even when wind speed is low or none due to vehicle stop, and further enhances the practical requirement of wind power generating device as being installed in a vehicle."
