Like reference characters in the drawings indicate the same or similar functionality throughout the various aspects.

[0022] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0023] FIG. 1 is a perspective view showing the overall structure of three types of private power generation systems for charging the battery of an electric vehicle in an embodiment of the present invention, and FIG. 2 is a side view showing the overall structure of three types of private power generation systems for charging the battery of an electric vehicle in an embodiment of the present invention.

[0024] The three types of private power generation systems for charging batteries of electric vehicles according to the embodiments of the present invention include a fixed panel 10, a first power generation unit 20, a second power generation unit 30, and a third power generation unit 40, as shown in the attached Figures 1 and 2.

[0025] The fixed panel 10 is formed on the outer ceiling surface of the electric vehicle 100 while being supported by a support base 11 .

[0026] That is, the support base 11 is a four-pillar structure, and when the fixing panel 10 is installed on the outer ceiling surface of the electric vehicle 100 through the support base 11, a space can be created between the outer ceiling surface of the electric vehicle 100 and the fixing panel 10 through which wind can flow in and pass through.

[0027] The first power generating unit 20 is formed in at least one space between the outer ceiling surface of the electric vehicle 100 and the fixed panel 10 as shown in the attached Figs. 3 to 6. The first power generating unit 20 generates electricity using wind power to charge the battery 101 of the electric vehicle 100, and includes a first rotating shaft 21, blades 22, a first rotor 23, and a first stator 24, and may further include a support plate 25, a second bearing 26, and a rubber elastic spring 27.

[0028] The first rotating shaft 21 has both ends rotatably coupled to an outer ceiling surface of the vehicle and an inner surface of the fixed panel 10 .

[0029] That is, one end of the first rotating shaft 21 may be rotatably coupled to a first bearing 24a (described later) included in the first stator 24. The other end of the first rotating shaft 21 may be rotatably coupled to a second bearing 26 connected to a support plate 25 formed on the inner surface side of the fixed panel 10 by a rubber elastic spring 27.

[0030] The rubber elastic spring 27 connects the support plate 25 and the second bearing 26 and prevents the first rotor 23 from slipping out of the first stator 24 .

[0031] The blades 22 are formed on the outer peripheral surface of the first rotating shaft 21 and rotate due to the wind flowing into the space between the external ceiling surface of the electric vehicle 100 and the fixed panel 10, thereby rotating the first rotating shaft 21.

[0032] That is, the blades 22 rotate to rotate the first rotating shaft 21 when the electric vehicle 100 is moving or parked / stopped and an external wind flows in.

[0033] The first rotor 23 is a disk-shaped structure and may be coupled and fixed to an outer circumferential surface of one end of the first rotating shaft 22. A first through hole 23a through which the first rotating shaft 21 passes may be formed in the center, and a plurality of first magnets 23b may be arranged on an adjacent surface around the first through hole 23a.

[0034] Here, the first magnets 23b, which are made up of a plurality of magnets, are permanent magnets arranged so that their north poles and south poles cross.

[0035] The first stator 24 is a disk-shaped structure that is fixed to the outer circumferential ceiling surface of the vehicle and faces the first rotor 23. The first bearing 24a to which one end of the first rotating shaft 21 passing through the first through hole 23a is coupled is formed in the center, and a first stator coil 24b facing the first magnet 23b can be disposed on an adjacent surface around the first bearing 24a. Electricity for charging the battery 101 is produced by the rotation of the first rotor 23.

[0036] The second power generating unit 30 is formed at least one or more on the bottom surface of the electric vehicle 100 as shown in the attached Figs. 7 to 11, and generates electricity by using the rotational force generated when the vehicle is running to charge the battery 101 of the electric vehicle 100, and may include a suspension 31, a second stator 32, a second rotor 33, and tires 34.

[0037] The suspension 31 is a pair of opposing structures connected to each other by a connecting shaft 31a on the bottom surface of the electric vehicle 100.

[0038] The bottom surface of the electric vehicle 100 may be configured to form a board 37 having a suspension hold 35 and a support plate 36 such that the suspension 31 may be supported by the support plate 36 .

[0039] The second stator 32 is a cylindrical structure, and may be fixed to both ends of the connecting shaft 31a that connects a pair of opposing suspensions 31. Second stator coils 32a that generate electricity to charge the battery 101 may be disposed on each of the second stator coils 32a.

[0040] The second rotor 33 is a tire rim-like structure covering the outer surfaces of one ends of the pair of opposing second stators 32, and may have a third bearing 33a to be rotatably coupled to the connecting shaft 31a between the pair of opposing first stators 32. A plurality of second magnets 33b are disposed on both sides adjacent to the third bearing 33a so that electricity is generated by the plurality of second stator coils 32a.

[0041] Here, the second magnets 33b, which are made up of a plurality of magnets, are permanent magnets arranged so that their north poles and south poles cross each other.

[0042] The tire 34 is fastened to the outer periphery of the second rotor 33 and contacts the ground when the vehicle is running to rotate the second rotor 33.

[0043] In addition, in an embodiment of the present invention, a female and male concave / convex portion (not shown) may be formed as a rainwater catcher between the second stator 32 and the second rotor 33. This is to prevent rainwater from accumulating between the second stator 32 and the second rotor 33, which may hinder electricity production, in areas with a lot of rain or snow.

[0044] The third power generation unit 40 is at least one or more solar collector plates formed on the plane of the fixed panel 10 and generating electricity using sunlight to charge the battery 101 of the electric vehicle 100.

[0045] Meanwhile, the electrical charging lines L1, L2, and L3 of the first power generation unit 20, the second power generation unit 30, and the third power generation unit 40 may be connected in parallel to the battery 101 and / or the solar generator 102. In this case, the electrical charging lines (L1 and / or L3) of the first power generation unit 20 and the second power generation unit 40 may be provided with an on or off contact unit 50 for determining whether or not the battery 101 and / or the solar generator 102 are charged. The electrical charging line L2 of the second power generation unit 30 may also be provided with an on or off contact unit 50' for determining whether or not the charging is performed. The on or off of the contact unit (50 and / or 50') may be configured to be controlled through a control switch (60 and / or 60') at the driver's seat of the vehicle to prevent overcharging, which is to turn off the charging of the battery 101.

[0046] As described above, in the three types of private power generation systems for charging the battery of an electric vehicle according to the embodiment of the present invention, as shown in the attached Figs. 1 to 12, when the camper type or passenger type electric vehicle 100 is parked / stopped, the battery 101 can be charged through the third power generation unit 40 that uses solar power and the solar power generation unit 102. When the electric vehicle 100 is parked / stopped and the wind is strong, the battery 101 can be charged through the first power generation unit 20 that uses wind power.

[0047] On the other hand, when the electric vehicle 100 is moving, the battery 101 can be charged not only through the third power generation unit 40 that uses solar power, but also through the first power generation unit 20 that uses wind power, and the second power generation unit 30 that uses the rotational force of the vehicle.

[0048] Meanwhile, even if the charging of the battery 101 using the solar light of the third power generating unit 40 is limited, while the vehicle is running, the battery 101 can be sufficiently charged through the first power generating unit 20 and the second power generating unit 30. Therefore, the driver of the electric vehicle 100 can eliminate the inconvenience of having to visit and wait at a charging facility, and can operate the electric vehicle 100 continuously for a long time while saving the cost of paying electricity fees during charging.

[0049] The technical concepts of the three types of self-power generation systems for charging the battery of an electric vehicle according to the present invention have been described above with reference to the accompanying drawings. However, this is merely an illustrative explanation of the best embodiment of the present invention and is not intended to limit the present invention.
