Abstract:
1. A wind generator system for electric vehicles, comprising: an electric car provided with an oblique concave-convex windshield-roof complex, with its front end down and its rear end upward; one or more retractable wind generators, supported by a frame, located in the high rear end of said concave-convex oblique windshield-roof complex; a guide element of the air, to guide the wind toward the wind generators, having its longitudinal profile U-shaped, with two ascending surfaces: one front and one rear, its upper surface concave, its lower surface convex and its lower end jointed on the top of said wind generators, being said guide element of the air retractable with said wind generators; one or more holes cut through the ascending surfaces of the said guide element of the air; one or more valves, having the same profile of the ascending surfaces of the guide element of the air, plug, in their rest position, said holes and are opened by the strong wind pressure that pushes from the front or the rear direction of the car, horizontally, on the ascending surfaces of the guide element of the air, where the valves are located; said guide element of the air split transversely in its lower end in two portions, both with their lower end hinged on the top of the frame of said wind generators and both held up by spring elements and able to rotate downward if pressed from their upper surface by a gust of wind that crosses the said valves opened in the opposite portion; said guide element of the air being its longitudinal profile U-shaped, has its upper surface concave and its lower surface convex while its upper ends bent in opposite way with their lower surface concave and their upper surface convex; two vertical deflectors located on the sides of said wind generators.
