BEST MODE

[0052] Hereinafter, preferred embodiments of the present invention configured to achieve the above objects will be described in detail with reference to the accompanying drawings.

[0053] FIG. 1 is a plan view of an electric vehicle equipped with the wind power generator to which the technique of the present invention is applied.

[0054] FIG. 2 is a side view of an electric vehicle equipped with the wind power generator to which the technique of the present invention is applied.

[0055] FIG. 3 is a side view of the wind power generator to which the technique of the present invention is applied.

[0056] FIGS. 4 to 13 are detailed cross-sectional views of respective parts of the wind power generator.

[0057] As shown in FIG. 3, the funnel-shaped cylindrical protective cover 101 of the wind power generator of the present invention is made of aluminum or high-strength plastics.

[0058] The funnel-shaped cylindrical protective cover 101 employs the Venturi principle of converting wind from outside into a wind speed by increasing the wind force.

[0059] A honeycomb protection net 102 is installed at a front portion of the funnel-shaped cylindrical protective cover 101 to remove foreign substances (paper, plastics, straw, stones, etc.) contained in the wind sucked from the outside such that an electric fan-type spiral suction fan 103 and a spiral suction fan 104 with blades having the same height can rotate at a high speed to generate as much electricity as possible.

[0060] The electric fan-type spiral suction fan 103 is installed on an inner front surface of the funnel-shaped cylindrical protective cover 101, and the spiral suction fan 104 with blades having the same height is installed on an inner rear space of the cover spaced apart from the electric fan-type spiral suction fan 103 by a distance (20 cm to 30 cm) to generate a larger amount of electricity using the sucked wind again and to ensure that the wind can safely move to a destination even if any one of the electric fan-type spiral suction fan 103 and the spiral suction fan 104 with blades having the same height breaks down.

[0061] The electric fan-type spiral suction fan 103 includes electric fan-type spiral suction blades in order to smoothly suction wind from the outside using the funnel-shaped cylindrical protective cover 101. The electric fan-type spiral suction blades have a height gradually lowered from the suction side to the discharge side, and the part for suctioning the wind is configured by blades which are slightly concave and bent in a spiral shape, which is intended to suction a large amount of wind without resistance and rotate at a high speed to generate a large amount of electricity in connection with the generator 107.

[0062] The spiral suction fan 104 with blades having the same height is horizontally installed to allow the wind passing through the electric fan-type spiral suction fan 103 to pass by the side thereof. The part for suctioning the wind is configured by blades which are slightly concave and bent in a spiral shape, which is intended to allow the spiral suction fans with blades having the same height to rotate in opposite directions at a high speed to generate a large amount of electricity in connection with the generator 107.

[0063] The bevel bobbin 108 of the electric fan-type spiral suction fan 103 is connected to the generator 107 using a bevel belt 109 to reduce frictional force during rotation thereof.

[0064] The spiral suction fans 104 with blades having the same height are connected to the generator 107 using bevel gears 112 to reduce frictional force during rotation thereof.

[0065] The electricity generated by the generator 107 is first stored in the storage battery 200 and is then used to drive the vehicle in connection with the electric drive motor 300.
