Description

Electric vehicles that can be charged by wind energy

[0001] The present invention relates to an electric vehicle that can be charged by wind energy and that can be driven using electricity generated by wind power generation.

[0002] As is well known, electric vehicles are being actively developed as a means to replace fossil fuel-powered vehicles.

[0003] This is because, along with the recent surge in oil prices, concerns about the depletion of fossil fuels and, especially, the problem of environmental pollution such as automobile exhaust fumes when using fossil fuels as a power source are becoming serious issues.

[0004] Due to this, the development of future automobiles such as hybrid automobiles, electric automobiles, fuel cell automobiles, and hydrogen automobiles that can replace gasoline or diesel as fuel has become a major concern in the automobile industry. Conventional electric automobiles are driven on the road after charging a certain amount of electricity, and when the charged battery is used up, it must be recharged and used again. However, since there are not many charging stations that charge the electricity in automobiles, charging is not easy.

[0005] Accordingly, there is a need for the development of electric vehicles that can increase driving distance by generating electricity while driving and supplying it to the battery.

[0027] Hereinafter, an embodiment of the present invention having the above-described features will be described in more detail with reference to the attached drawings.

[0028]

[0029] An electric vehicle capable of being charged by wind energy according to an embodiment of the present invention comprises: an air intake part (110) formed on the front of an electric vehicle (10) that drives a wheel (12) by an electric motor (11) to allow wind to flow in while driving; a turbine (120) formed at the rear end of the air intake part (110) that rotates by wind; a rotor (131) coupled to a rotational shaft (121) extended from the turbine (120); and a stator (132) arranged in a ring shape on the outside of the rotor (131), a power generation part (130) that generates electric power by the rotation of the rotor (131), a power supply part (140) that converts electric power by the power generation part (130) into a chargeable voltage to charge a battery (141) and supplies a driving voltage from the battery (141) to the electric motor (11); and an electrical system that electrically connects the battery (141) and the electric motor (11). The gist of the invention is to enable driving using power generated by wind power generation, including a controller (150) that connects and controls charging from a power generation unit (130) to a battery (141).

[0030]

[0031] Hereinafter, with reference to FIGS. 1 to 6, an electric vehicle capable of being charged by wind energy of the aforementioned configuration will be described in detail as follows.

[0032]

[0033] First, referring to FIGS. 1 and 2, the air inlet (110) is formed on the front of an electric vehicle (10) that drives a wheel (12) by rotating it with an electric motor (11), and is formed so that wind is smoothly introduced when driving at a certain speed or higher to induce a turbine (120).

[0034] Here, the air inlet (110) can be formed as a single configuration at the bottom of the central license plate or inside the radiator or as a pair on both sides adjacent to the fog lamp to communicate with the turbine (120).

[0035] Meanwhile, the electric vehicle (10) further includes a sensor unit (160) composed of a wind speed sensor (161) formed on the front of the vehicle to measure wind speed during driving, and a rain sensor (162) to measure rainfall during the rainy season, and as illustrated in FIG. 4, the air inlet unit (110) is formed by recessing in the center or both sides of the front lower part of the electric vehicle (10) to guide the inflow of wind, and an opening (112) formed in the air inlet (111) to open and close the air inlet (111), and when a measurement value above a certain level is detected by the wind speed sensor (161), the controller (150) operates the opening (112) to open the air inlet (111) to allow wind to flow in, and closes the opening (112) when stopped, washed, or driving at a low speed of 15 km / h or less to prevent external It is possible to block the inflow of foreign substances, and when the inflow of rainwater into the air inlet (111) is detected by the rain sensor (162), the controller (150) can operate the opening (112) to close the air inlet (111).

[0036] In addition, the controller (150) can control the degree of opening and closing of the gate (112) to control the rotation speed of the rotation shaft (121) when the rotation speed of the rotation shaft (121) is greater than a preset constant speed, thereby enabling stable power production.

[0037] Alternatively, a semicircular brake pad (not shown) may be coupled to the rotating shaft (121), so that when the rotating shaft (121) rotates excessively, the controller (150) controls the brake pad to reduce the rotation speed of the rotating shaft (121) to maintain the structural stability of the blade (122) and reduce friction between the rotating shaft (121) and the bearing (123) to minimize deformation due to high temperatures.

[0038]

[0039] In addition, referring to FIG. 4, a filter net (113) formed at the front end of the air inlet (111) to block the inflow of external foreign substances and a barrier formed at the front of the filter net (113) to open and close to protect the filter net (113) are further included, and when driving at a certain speed or higher, the controller (150) can open the barrier and block the inflow of external foreign substances through the filter net (113), thereby minimizing contamination or damage to the turbine (120).

[0040] In addition, referring to FIG. 4, the air inlet passage (111) is formed with a tapered cross-sectional structure whose diameter narrows toward the turbine (120), thereby increasing the flow velocity and increasing the rotational force of the blade (122).

[0041] Meanwhile, an exhaust port (114) communicating with an air inlet passage (111) is formed at the rear of the electric vehicle (10), and the size of the exhaust port (114) is formed to be relatively larger than the size of the air inlet passage (111), so that the introduced air can be discharged smoothly.

[0042] Here, the exhaust port (114) may be formed to extend upward at a certain angle from the ground so that the air discharged from the exhaust port (114) has minimal contact with the ground and is discharged upward (see Fig. 2), thereby supplementing driving stability by allowing the rear wheels to drive in close contact with the ground by air pressure.

[0043] In addition, according to the measurement value by the wind speed sensor (161), the controller (150) can drive the opening / closing port (112) to maintain the flow rate of wind supplied to the turbine (120) within a certain level range, thereby maintaining the rotational amount of the turbine (120) within a certain level range to enable stable power generation by the power generation unit (130), thereby preventing excessive current from flowing to the battery (141) and ensuring electrical stability.

[0044]

[0045] In addition, as illustrated in FIG. 4, a discharge hole (115) is formed on the bottom surface of the air inlet (111) at the front or rear end of the blade (122), so that foreign substances such as dust and rainwater that have entered from the outside are discharged to the outside, thereby preventing contamination or corrosion of the turbine (120) and power generation unit (130), thereby increasing durability.

[0046] In addition, although not shown, a heating wire is built into the air intake passage (111), so that ice attached to the inside and outside of the air intake passage (111) in winter is melted and removed, and a separate driving motor (not shown) gear-connected to the ring gear (not shown) of the rotation shaft (121) rotates the blade (122) in reverse to remove moisture, thereby preventing moisture from entering the blade (122) during driving, thereby preventing corrosion, etc., and increasing durability.

[0047]

[0048] Next, the turbine (120), as shown in FIGS. 1 and 3, is formed at the rear end of the air inlet (110) and rotates within a certain speed range by wind power flowing in from the air inlet (110).

[0049] Specifically, referring to FIGS. 4 and 5, the turbine (120) is configured with a blade (122) coupled to a rotation shaft (121) and structured to rotate in only one direction, a bearing (123) guiding the rotation of the rotation shaft (121), and an encoder (not shown) measuring the rotational speed of the rotation shaft (121), and the controller (150) controls whether or not to charge the battery (141) from the power generation unit (130) according to the rotational speed by the encoder, thereby supplying power generated by rotational force greater than a certain rotational speed to the battery (141) to enable stable charging.

[0050] In addition, although not shown, the rotation axis (121) is formed by connecting the front and rear axes by a coupling, and the controller (150) can control the coupling when the battery (141) is fully charged to block the linkage of the front and rear axes, thereby preventing overcharging of the battery (141).

[0051] Alternatively, when the battery (141) is fully charged, the controller (150) may operate the opening (112) or the barrier to close it, thereby blocking the inflow of air and stopping power generation by the turbine (120).

[0052] In addition, the controller (150) may detect the reverse rotation of the blade (122) through a sensor (not shown) other than the preset direction, and switch to cut off the connection with the battery, thereby blocking reverse flow from the battery (141) to the power generation unit (130).

[0053] In addition, although not shown, the coupling may include a transmission gearbox, so that in case of strong winds or high-speed driving exceeding 100 km / h, the controller (150) may control the transmission gearbox to ensure that the rotation shaft (121) rotates stably within a certain range to produce a certain amount of power, thereby suppressing excessive voltage or current peaks and thus suppressing overload of the battery (141).

[0054]

[0055] Meanwhile, referring to FIGS. 5 and 6, an auxiliary blade (124) is formed at the rear end of the blade (122) to form a double blade structure, and the exhaust port (114) is provided with a damper (not shown) and a return induction path (125), so that, optionally, air passing through the turbine (120) can be immediately discharged to the outside of the vehicle (a), or re-induced through a pipe to the upper side or lower side of the auxiliary blade (124) to reinforce the rotational force of the rotational shaft (121), thereby maintaining a rotational force above a certain level even when driving at low speeds, thereby enabling stable power production.

[0056] Here, the return guide (125) may be configured as a single configuration and connected to the upper side or the lower side of the auxiliary blade (124), or may be configured as a pair of opposing return guides, such that one return guide (125) is connected to the upper side of the auxiliary blade (124) and the other return guide (125) is connected to the lower side of the auxiliary blade (124), thereby further increasing the rotational force of the rotation shaft (121).

[0057]

[0058] In addition, the blades (122) are formed in two stages by being respectively arranged at the front and rear ends of the rotation axis (121), thereby expanding the contact area with air and increasing the rotational force. Referring to Fig. 5 (a), a nacelle (122a) is formed protrudingly at the center of the front end of the blade (122), thereby enabling the pressure applied to the blade (122) by the air to be evenly distributed.

[0059]

[0060] Next, the power generation unit (130), referring to FIGS. 1 and 3, is composed of a rotor (131) coupled to a rotating shaft (121) extended from a turbine (120), and a stator (132) arranged in a ring shape on the outside of the rotor (131) and having a coil wound thereon, so as to generate power by induced electromotive force by the rotation of the rotor (131) and supply it to the power supply unit (140).

[0061]

[0062] Next, the power supply unit (140), referring to FIGS. 1 and 3, converts the electric power generated by the power generation unit (130) into a stable voltage that can be charged, charges the battery (141), and supplies a driving voltage from the battery (141) to the electric motor (11).

[0063]

[0064] Next, the controller (150) electrically connects the battery (141) and the electric motor (11) through the electrical system wired to the electric vehicle (10), and controls stable charging from the power generation unit (130) to the battery (141).

[0065] Meanwhile, a contamination sensor (not shown) for detecting the contamination level of the air intake (110) is further provided, and when contamination above a certain level is detected by the contamination sensor, the controller (150) may, when stopped, rotate the turbine (120) in the opposite direction to the rotation direction for power generation, thereby blowing out foreign substances attached to the opening (112) or filter net (113) to forcibly remove them.

[0066]

[0067] In addition, referring to FIG. 2, a solar cell module (13) may be arranged on the upper part of the body of an electric vehicle (10) so that the battery (141) can be charged even when parked or driving.

[0068]

[0069] Accordingly, by configuring an electric vehicle capable of being charged by wind energy as described above, it is possible to drive using electricity generated by wind power generation, thereby reducing air pollution by not using fossil fuels, reducing the cost of charging at electric charging stations, and enabling long-term driving by electric charging even when driving long distances or in areas where electric charging station infrastructure is not established.
