[0039] It should be understood that the various embodiments of the present invention are different from each other, but not mutually exclusive. For example, without departing from the spirit and scope of the present invention, the specific shapes, structures and features described herein for one embodiment may be implemented by other embodiments. In addition, it should be understood that the position or arrangement of individual components in each disclosed embodiment may be changed without departing from the spirit and scope of the present invention. In the accompanying drawings, similar reference numerals represent the same or similar functions at multiple levels.

[0040] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0041] Figure 1 is a perspective view showing the overall structure of a three-type self-generation system for charging a battery of an electric vehicle as an embodiment of the present invention; Figure 2 1 is a side view showing the overall structure of a three-type self-generation system for charging a battery of an electric vehicle as an embodiment of the present invention.

[0042] like Figure 1 and 2 As shown in FIG. 1 , the three-type self-generating system for battery charging of an electric vehicle according to an embodiment of the present invention includes: a fixed panel 10 , a first power generating part 20 , a second power generating part 30 and a third power generating part 40 .

[0043] The fixing panel 10 is formed to be supported on an outer ceiling of the electric vehicle 100 through a support 11 .

[0044] That is, the support members 11 are four columnar components. When the fixed panel 10 is set on the external ceiling of the electric vehicle 100 through the support members 11, a space for wind to flow in and pass through can be formed between the external ceiling of the electric vehicle 100 and the fixed panel 10.

[0045] like Figures 3 to 6 As shown, the first power generation unit 20 is formed at least in the space between the outer ceiling of the electric car 100 and the fixed panel 10. The first power generation unit 20 uses wind power to charge the battery 101 of the electric car 100, and includes: a first rotating shaft 21, blades 22, a first rotor 23 and a first stator 24, and may also include: a support plate 25, a second bearing 26 and a rubber elastic spring 27.

[0046] Both ends of the first rotating shaft 21 are rotatably coupled to an outer ceiling of the vehicle and an inner surface of the fixed panel 10 .

[0047] That is, one end of the first rotating shaft 21 is rotatably coupled to a first bearing 24a, which will be described later, included in the first stator 24. The other end of the first rotating shaft 21 is rotatably coupled to a second bearing 26 connected to a support plate 25 formed on the inner surface side of the fixed panel 10 via a rubber elastic spring 27.

[0048] The rubber elastic spring 27 is used to connect the support plate 25 and the second bearing 26 and prevent the first rotor 23 from being separated from the first stator 24 .

[0049] The blade 22 is formed on an outer circumferential surface of the first rotating shaft 21 and is rotated by wind flowing into a space between an outer ceiling of the electric vehicle 100 and the fixed panel 10 , thereby rotating the first rotating shaft 21 .

[0050] That is, when the electric vehicle 100 is in a running or parked state and external wind flows in, the blades 22 rotate and the first rotating shaft 21 rotates.

[0051] The first rotor 23 is a disc-shaped member and can be fixedly coupled to the outer peripheral surface of one end of the first rotating shaft 21. A first through hole 23a for passing the first rotating shaft 21 can be formed at the center, and a plurality of first magnets 23b can be provided on adjacent surfaces centered on the first through hole 23a.

[0052] The plurality of first magnets 23 b are permanent magnets in which N poles and S poles are arranged crosswise.

[0053] The first stator 24 is a disc-shaped member fixed to the outer circumferential ceiling of the vehicle and facing the first rotor 23. The first bearing 24a is formed at the center to be coupled to one end of the first rotating shaft 21 passing through the first through hole 23a, and a first stator coil 24b facing the first magnet 23b may be provided on an adjacent surface centered on the first bearing 24a. According to the rotation of the first rotor 23, power for charging the battery 101 is generated.

[0054] like Figures 7 to 11 As shown, at least one second power generation unit 30 is formed on the bottom surface of the electric vehicle 100, and generates electricity by using the rotational force of the vehicle when it is running, so as to charge the battery 101 of the electric vehicle 100. The second power generation unit 30 may include: a suspension 31, a second stator 32, a second rotor 33 and a tire 34.

[0055] The suspension 31 is a pair of members facing each other and connected by a connection shaft 31 a on the bottom surface of the vehicle of the electric vehicle 100 .

[0056] A plate 37 having a suspension support portion 35 and a support plate 36 is formed on the bottom surface of the electric vehicle 100 so that the suspension 31 can be supported by the support plate 36 .

[0057] The second stator 32 may be a cylindrical member and may be fixed to both ends of the connection shaft 31a for connecting the pair of opposing suspensions 31. Second stator coils 32a for generating power for charging the battery 101 may be provided.

[0058] The second rotor 33 is a rim-shaped member that covers the outer surface of one end of the pair of second stators 32 formed to face each other, and may include a third bearing 33a rotatably coupled to the connecting shaft 31a between the pair of second stators 32. A plurality of second magnets 33b are provided on two adjacent surfaces centered on the third bearing 33a to generate electricity in the plurality of second stator coils 32a.

[0059] The second magnets 33b formed in plurality are permanent magnets in which N poles and S poles are arranged crosswise.

[0060] The tire 34 is fastened to an outer circumference of the second rotor 33 and contacts the ground when the vehicle travels to rotate the second rotor 33 .

[0061] In addition, as an embodiment of the present invention, a male and female concave and convex portion (not shown) may be formed between the second stator 32 and the second rotor 33 for collecting rainwater. This is to prevent rainwater from accumulating between the second stator 32 and the second rotor 33 in areas with heavy rain and snow, which would hinder power generation.

[0062] At least one third power generation unit 40 is formed on the plane of the fixed panel 10 , and is at least one solar thermal collector panel that generates electricity using sunlight to charge the battery 101 of the electric car 100 .

[0063] On the other hand, 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 with the battery 101 and / or the solar generator 102. In this case, a contact portion 50 for connecting or disconnecting may be formed in the electrical charging lines (L1 and / or L3) of the first power generation unit 20 and the second power generation unit 30, respectively, which is used to determine whether the battery 101 and / or the solar generator 102 are charged or not. A contact portion 50' for connecting or disconnecting to determine whether the battery 101 and / or the solar generator 102 are charged or not may also be formed in the electrical charging line L2 of the second power generation unit 30. The connection or disconnection of the contact portion (50 and / or 50') may be controlled by a control switch (60 and / or 60') on the driver's seat of the vehicle to prevent overcharging, which is to shut down the charging of the battery 101.

[0064] As mentioned above, Figures 1 to 12 As shown, according to the three-type self-generating system for battery charging of an electric vehicle according to an embodiment of the present invention, when the camping type or sedan type electric vehicle 100 is in a parking / stopping state, the battery 101 can be charged by the third power generation unit 40 using solar energy and the solar generator 102. When the electric vehicle 100 is in a parking / stopping state, if the wind is strong, the battery 101 can be charged by the first power generation unit 20 using wind power.

[0065] On the contrary, when the electric car 100 is running, the battery 101 can be charged not only by the third power generation unit 40 utilizing solar energy, but also by the first power generation unit 20 utilizing wind power and the second power generation unit 30 utilizing running rotational force.

[0066] On the other hand, even if the charging of the battery 101 by the third power generation unit 40 using solar energy is limited, when the vehicle is in a driving state, the battery 101 can be fully charged by the first power generation unit 20 and the second power generation unit 30. Therefore, the inconvenience caused by the driver of the electric vehicle 100 going to the charging facility and waiting can be improved, and the electric vehicle 100 can be operated continuously for a long time while reducing the cost of paying electricity bills during charging.

[0067] The technical concept of the three types of self-generating systems for charging the battery of the electric vehicle of the present invention has been described above in conjunction with the accompanying drawings, but this is only an example of the best embodiment of the present invention and does not constitute a limitation to the present invention.

[0068] Therefore, the present invention is not limited to the above-mentioned specific preferred embodiments. Without departing from the gist of the present invention as claimed in the claims, any person skilled in the art in the technical field to which the present invention belongs can implement various modifications, and such changes are also within the scope described in the claims.
