Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bike equipped with a wind power generation system,

The present invention relates to a wind power generation system, and more particularly, to a wind power generation system capable of obtaining electric energy using wind power and minimizing a resistance acting on a vehicle body, thereby increasing a travel distance and reducing a charging frequency of a battery To a bike equipped with a wind power generation system.

Generally, a bike is a two-wheeled automobile, and its structure is simple, simple and easy to drive, and thus it is widely used as a short-distance transportation vehicle. These bikes have a disadvantage of relatively high operation cost as a means of moving fossil energy such as petroleum as an energy source.

And, fossil energy is depleted as time goes by with limited resources, and the price is continuously rising. In particular, fossil energy is not only exhausting various exhaust gases that pollute the atmospheric environment during its use, but also discharging a large amount of carbon dioxide, which is a major cause of global warming, Various research and development activities have been carried out for reduction, and an electric bike has been developed as an alternative to transfer electricity to an energy source.

The electric bike has a disadvantage in that it can not travel when the electric power of the battery is discharged because the traveling distance is short because the electric bike is driven by using the charged power of the battery mounted on the vehicle body.

Accordingly, in recent years, a bike having a self-power generation system capable of charging electricity to the bike itself has been developed. For example, Korean Utility Model Laid-Open No. 20-2009-0012821 discloses a wind power electric motorcycle capable of generating electricity by wind power.

1, the electric power of the battery 118 is supplied from an electric power supply unit to drive an engine motor 122, and a rotational power output from an engine motor is transmitted from a transmission An air inlet 102 formed in front of the front cowl 100 for collecting outside winds in one direction and concentrating the air in the front cowl during traveling of the motorcycle, A wind turbine (104) having a rotating shaft (106) provided in the cowl and generating a rotating force by a wind force flowing into the cowl; at least one And the above generators 108 and 110.

The above-described conventional wind power electric motorcycle can convert the wind power generated during traveling into electric energy, charge the battery, and drive the engine motor with the charged electric energy to rotate the wheel. However, the following problems are involved.

In the conventional wind power generation electric motorcycle, since the components for power generation such as the wind power fan 104 are disposed inside the air inlet 102 recessed in front of the front cowl 100, the inflow wind can not easily flow out. It causes a problem that the driving speed is decreased and the consumption of electric energy is increased rather than acting as a resistance during driving.

Conventionally, a wind turbine electric motorcycle has a structure in which the wind fan 104 is rotated using only the air flowing into an air inlet, so there is a limit to the electric power generation efficiency because of low air volume and low wind pressure.

In addition, the conventional wind turbine electric motorcycle is disadvantageous in that since the components for power generation such as the wind power fan 104 are disposed in front of the front cowl 100, the aesthetic appearance is poor and the merchantability is deteriorated.

FIG. 4 is a schematic view showing a wind turbine of a bike having a wind power generation system according to an embodiment of the present invention, and schematically shows a shape that appears on a plane. FIG.

2 to 4, a bike having a wind power generation system according to an embodiment of the present invention generates electricity by wind power on a vehicle body provided with a front wheel a, a rear wheel b, and a handle c. A wind turbine 3, a wind turbine 3, a power generator 4 and a generator 5, and an electric power generated by the generator. And a battery (not shown) charged with energy is provided.

The air moving duct 1 is formed as a passage through which a wind to be flowed to the bike is moved as a single body in a body case d installed in a body of the bike or is built into a body case d.

The air inlet member 11 has a wide entrance side, induces a relatively large area of wind, pivots through the helical blades 11b, and then flows into the air moving duct 1 And performs the function of inflow.

The connecting duct 2 is a cylindrical duct to which the outlet portions of the air moving ducts 1 are connected, and the amplifying duct 71 of the wind power amplifying member 7, which will be described later, is connected to the end thereof.

6 is a partially cutaway perspective view showing a wind power amplifying member of a bike having a wind power generation system according to an embodiment of the present invention.

The wind power amplifying member 7 is for increasing the wind speed of the wind supplied to the wind turbine 3 or performing the function of swirling the wind to improve power generation efficiency. In this embodiment, as shown in FIG. 6, An amplifying duct 71 formed in a cylindrical shape connected to the connecting duct 2 and a screw 72 provided inside the amplifying duct 71 so that the wind can be turned. Since the wind supplied to the blade 31b of the wind turbine 3 is in the form of a whirl, the wind power amplifying member 7 has an advantage in that the rotational force is increased and the wind power can be further increased.

In addition, since the wind pressure amplifying member 7 flows out at a high speed while the incoming wind forms a whirl-like shape, the inside pressure becomes low and the outside becomes high pressure. Therefore, a separate air inlet (not shown) is connected to the connection portion with the wind turbine In addition, external air can be further introduced through the air inlet to supply a larger amount of wind to the wind turbine while forming a rising airflow of a whirling type, thereby improving power generation efficiency.

The wind turbine (3) is configured to rotate by wind power applied from a wind power amplifying member (7) connected to the connecting duct (2) as a component for converting wind power into rotational motion.

As shown in FIG. 4, in the present embodiment, the rotating body 31 having the turbine shaft 31c at the center is installed in the wind turbine 3, And a turbine cover (32) installed so as to cover the outside of the rotating body (31). A plurality of blades 32b are arranged in a circumferential direction between a pair of circular plates 31a spaced apart from each other at regular intervals and the turbine cover 32 is formed as shown in Fig. The air intake hole 32a which is the air to which the end of the wind power amplifying member 7 is connected to the circular body formed so as to receive the rotating body 31 therein as shown in FIG. (32b) are formed. At this time, the air outlet hole 32b is formed at a position close to the inlet hole 32a, which is air, to be discharged after the inflowed wind is turned. The turbine cover 32 is preferably formed such that the wind turbine 3 as well as the speed reducer 4 and the generator 5 can be received as shown in Fig.

The speed reducer 4 is configured to increase the rotational force of the wind turbine 3 so as to have a revolution number capable of generating electricity. In this case, the input shaft 4 is coupled to the turbine shaft 31c of the wind turbine 3, A gear 41, a multi-stage speed increasing gear, and an output side gear 44. The speed increasing gear includes a first speed increasing gear 42 engaged with the input side gear 41 and a second speed increasing gear 43 coupled to the output side gear 44 on the shaft of the first speed increasing gear 42, .

The generator 5 is constituted by installing a normal generator determined and calculated according to the size, capacity and the like of the wind turbine so that the generator shaft is coupled to the output gear 44 of the speed reducer 3 and is rotated to generate electricity .

3, the bike having the wind power generation system according to the present invention is formed with a water discharge port 12 for preventing water from flowing into the wind turbine 3. The water outlet 12 is formed of a hose having one end connected to the air moving duct 1 and one end connected to the lower end of the vehicle body to be introduced into the air moving duct 1, As a component for discharging the moisture, corrosion and contamination of the wind turbine and the like can be prevented, and durability can be improved.

Hereinafter, the operation of a bike having a wind power generation system according to an embodiment of the present invention will be briefly described.

As described above, when the wind power generation system including the air moving duct 1, the connecting duct 2, the wind turbine 3, the wind turbine 4, and the generator 5 is mounted on the body of the bike, The air flows in through the air inflow member 11 and moves along the air moving duct 1. [ At this time, the moisture contained in the air is discharged through the water outlet 12 connected to the air moving duct 1.

The wind traveling through the air moving duct 1 installed at various places is concentrated in the connecting duct 2 and is moved to the wind power amplifying member 7 and then flows into the wind turbine 3. At this time, since the wind power amplifying member 7 rotates the wind supplied to the wind turbine 3 to form a whirlwind wind, the rotational force is increased and a relatively large wind force can be applied.

When the wind is introduced into the interior of the wind turbine 3 and the rotation operation is performed as described above, the input side gear 41 coupled to the turbine shaft 31c is rotated and the first speed increasing gear 42 and the second speed increasing gear 43 and then transmitted to the output side gear 44. The power generator shaft coupled to the output side gear 44 is rotated to generate electric power by the generator. The electric energy generated from the generator is used as an energy source of a traveling motor (not shown) for traveling the bike after being charged in the battery.
