Description

Technical Field

[0001] The present invention relates to a mobility vehicle, and more specifically, to a technique in which a flap is provided below the rotor to guide outside air into the interior of the wing section of the mobility vehicle to cool the rotor motor, inverter, or motor and inverter, or the battery of the mobility vehicle. Background Technology

[0002] Recently, an airborne mobile vehicle has been developed, which is equipped with rotors and fixed wings to enable the airborne mobile vehicle to take off and land vertically by operating motors and inverters. The motors and inverters are mounted on the rotors that use high-voltage batteries, and the fixed wings are used for cruise after vertical takeoff to reduce the energy consumption of the high-voltage batteries.

[0003] However, in traditional air-mobile vehicles, motors, inverters, or batteries located inside the fixed wing or fuselage of the air-mobile vehicle operate for extended periods, thus generating heat. Therefore, cooling devices are being developed to introduce outside air into the fuselage or fixed wing of the air-mobile vehicle to cool the motors, inverters, or batteries.

[0004] However, the technology used to cool the motors, inverters, or batteries of air-mobile vehicles continues to require cooling time points based on the temperature of the motors, inverters, or batteries, and the air intake equipment is configured to introduce outside air while the air-mobile vehicle is cruising, which may reduce the flight performance of the air-mobile vehicle during cruising.

[0005] The information disclosed in the background section of this invention is intended only to enhance the understanding of the general background of the invention and should not be construed as an admission or any implication that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0006] Various aspects of the present invention aim to provide an air-mobile vehicle that allows outside air to flow into the interior of the air-mobile vehicle through at least one air flap, the air flap being positioned below a fixed wing and rotatably mounted within at least one opening provided in the air-mobile vehicle to cool the rotor motor, inverter, or motor and inverter, or at least one battery of the air-mobile vehicle, and when cooling of the motor, inverter, or motor and inverter, or at least one battery is not required, allows at least one air flap to cover at least one opening to improve the flight performance of the air-mobile vehicle.

[0007] According to various aspects of the invention, the above and other objectives can be achieved by providing an air-mobile vehicle comprising: at least one damper, positioned below the mounting location of each rotor and rotatably mounted into at least one opening in the air-mobile vehicle to guide the flow direction of air flowing into the area below each rotor or the flow direction of air flowing into the interior of the air-mobile vehicle above the at least one opening; an actuator, coupled to the at least one damper and configured to rotate the at least one damper to guide air that has passed through the at least one damper to a motor, inverter, or motor and inverter of each rotor, or at least one battery; and a controller, electrically connected to the actuator and configured to control the actuator based on the driving state of the air-mobile vehicle or the temperature of the motor and inverter of each rotor or the temperature of the at least one battery to control the flow of air that has passed through the at least one damper.

[0010] When at least one damper plate rotates toward the rotor in a first direction, air flowing into the area below each rotor can pass through at least one damper plate and flow into the interior of the boom to cool the motor and inverter. When at least one damper plate rotates in a second direction opposite to the first direction of the rotor, air flowing into the area in front of at least one damper plate can pass through at least one damper plate and flow through the interior of the boom to the interior of the fixed wing to cool at least one battery.

[0012] At least one damper can cover at least one opening in the initial state to prevent air flowing to the area below each rotor from flowing through at least one opening into the interior of the air-mobile vehicle.

[0013] The air-mobile vehicle further includes a first temperature sensor configured to measure the temperature of a motor and an inverter, and a second temperature sensor coupled to a controller and configured to measure the temperature of at least one battery, and the controller may be configured to control the actuator based on the temperature measured by the first temperature sensor or the temperature measured by the second temperature sensor.

[0014] The controller can be configured to control the actuator such that when the temperature measured by the first temperature sensor is equal to or greater than a first temperature, air flowing into the area below each rotor or air flowing into front of at least one damper is directed through at least one damper to the motor and inverter.

[0015] The controller can be configured to control the actuator such that when the temperature measured by the second temperature sensor is equal to or greater than the second temperature, air flowing into the area in front of at least one damper plate is guided through at least one damper plate to at least one battery.

[0016] The controller can be configured to control the actuator such that when the temperature measured by the first temperature sensor and the temperature measured by the second temperature sensor are equal to or lower than a predetermined third temperature, at least one damper flap covers at least one opening.

[0018] The controller can be configured to control the actuator such that, when the air-mobile vehicle is cruising, air flowing into the area in front of at least one damper plate is guided through at least one damper plate to at least one battery.

[0019] The controller can be configured to control the actuator such that at least one damper flap covers at least one opening when the air-mobile vehicle is cruising.

[0020] At least one damper plate can be configured as multiple damper plates, and an actuator can be connected to at least one damper plate to make at least one damper plate rotate simultaneously.

Figure 2 This is an exemplary perspective view showing how air is directed to a motor 300 and an inverter 400 by a damper 100 of an airborne motor vehicle according to various exemplary embodiments of the present invention to cool the motor 300 and the inverter 400. Figure 3 yes Figure 2 Cross-sectional view, Figure 4 This is an exemplary perspective view showing air being directed to a battery 500 by a damper 100 of an airborne motor vehicle according to various exemplary embodiments of the present invention, and Figure 5 yes Figure 4 Cross-sectional view.

[0041] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The present invention will describe an air-mobile vehicle according to various exemplary embodiments thereof.

[0042] In an airborne mobile vehicle according to various exemplary embodiments of the present invention, a rotor 800 and a fixed wing 700 are provided. The airborne mobile vehicle can take off and land vertically, and can cruise with the fixed wing 700 after taking off vertically.

[0043] According to various exemplary embodiments of the present invention, an airborne motor vehicle can be operated by a battery 500, or by an internal combustion engine other than a battery 500.

[0044] An airborne vehicle according to various exemplary embodiments of the present invention includes: damper flaps 100 positioned below the mounting location of each rotor 800 and rotatably mounted inside an opening 610 provided in the airborne vehicle to guide the flow direction of air flowing into the area below the rotor 800 or the flow direction of air flowing into the interior of the airborne vehicle above the opening 610; an actuator 200 configured to rotate the damper flaps 100 to guide air that has passed through the damper flaps 100 to the motor 300, inverter 400, or motor 300 and inverter 400 of the rotor 800, or battery 500; and a controller 10 configured to control the actuator 200 to control the flow of air that has passed through the damper flaps 100 based on the driving state of the airborne vehicle or the temperature of the motor 300 and inverter 400 of the rotor 800 or the temperature of the battery 500.

[0045] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, each rotor 800 has a vertically arranged rotation axis. These rotors can be mounted on an airborne vehicle. An opening 610 can be formed below each rotor 800, and a damper 100 can be provided to operate to open or close the opening 610.

[0046] When the damper 100 opens the opening 610, the damper 100 can guide outside air into the interior of the airborne motor vehicle, and guide outside air to the motor 300 and inverter 400 or battery 500 of the rotor 800 according to the opening direction of the opening 610, and is configured to cool the heated motor 300 and inverter 400 or the heated battery 500 by outside air.

[0047] The actuator 200 is connected to the damper 100 to rotate the damper 100, and the actuator can be operated so that the damper 100 opens the opening 610 only when needed.

[0048] The controller 10 is connected to the actuator 200 to control the operation of the actuator 200, and can control the actuator 200 to open or close the opening 610 of the damper plate 100 based on the driving status of the airborne motor vehicle or the temperature difference between the outside air temperature and the temperature of the motor 300 and the inverter 400 or the temperature difference between the outside air temperature and the battery 500.

[0049] The damper plate 100 is controlled to open the opening 610 to allow outside air to flow into the airborne vehicle through the operation of the damper plate 100 to cool the motor 300 of the rotor 800, the inverter 400, or the battery 500 of the airborne vehicle. If cooling is not required, the damper plate 100 is controlled to close the opening 610 to facilitate the effective flight of the airborne vehicle.

[0050] The actuator 200 may include: a drive unit 210 that is driven to rotate its rotation axis; and a connecting rod 220 configured such that one end portion of the connecting rod is rotatably connected to the rotation axis 230 of the drive unit 210, and the other end portion of the connecting rod is connected to the damper 100 to rotate the damper 100 based on the rotation of the drive unit 210.

[0051] like Figure 2 As shown, the actuator 200 may include: a drive unit 210, driven to rotate its rotation axis; and a connecting rod 220 configured to connect the rotation axis to the damper plate 100 to rotate the damper plate 100 based on the rotation of the rotation axis.

[0052] Multiple connecting rods 220 are provided, so that the rotational force of the rotating shaft can be transmitted to the damper plate 100.

[0053] In an exemplary embodiment of the present invention, the rotating shaft 230 includes a slot 240, and the end portion of the connecting rod 220 is slidably connected to the slot 240 in the rotating shaft 230 of the drive device 210.

[0054] Therefore, when the controller 10 controls the drive unit 210, the drive unit 210 can rotate the damper plate 100 forward or backward.

[0055] In addition to the structure including the drive unit 210 and the connecting rod 220, as shown in the figure, the actuator 200 can be formed with a linear device or with various other structures.

[0056] The rotor 800 is mounted on the boom 600 of the air mobility vehicle, such that the motor 300 and inverter 400 of each rotor 800 are located inside the boom 600. The battery 500 is installed inside the fixed wing 700 of the air mobility vehicle. The damper 100 is mounted on the boom 600 and rotated by the operation of the actuator 200 to guide airflow to the area below the rotor 800 or to the airflow in front of the damper 100, so that air enters the interior of the boom 600 or enters the interior of the fixed wing 700 through the interior of the boom 600.

[0057] An air-mobile vehicle may include a fixed wing 700 extending from its fuselage and a boom 600 extending from the fixed wing 700, a battery 500 may be installed in the fixed wing 700, and a rotor 800 may be installed on the upper surface of the boom 600.

[0058] The rotorcraft 800 can be used for vertical takeoff and landing of air-mobile vehicles, while the fixed-wing 700 can be used for cruising of air-mobile vehicles.

[0059] Therefore, the motor 300 and inverter 400 of the rotor 800 can be positioned inside the boom 600, and the damper 100 is positioned on the boom 600 below the rotor 800. When the damper 100 opens the opening 610, it can guide outside air into the interior of the boom 600 to cool the motor 300 and inverter 400 of the rotor 800, or guide outside air through the interior of the boom 600 to the interior of the fixed wing 700 to cool the battery 500. Meanwhile, as... Figure 2 and 4 The reference numeral 620 in the figures indicates an outlet provided in the boom 600 to be fluidly connected with the opening 610.

[0060] When the damper plate 100 rotates toward the rotor 800, the air flowing to the area below the rotor 800 can pass through the damper plate 100 and flow into the interior of the boom 600 to cool the motor 300 and the inverter 400. When the damper plate 100 rotates in the opposite direction to the rotor 800, the air flowing into front of the damper plate 100 can pass through the damper plate 100 and flow through the interior of the boom 600 to the interior of the fixed wing 700 to cool the battery 500.

[0061] like Figure 2 and Figure 3 As shown, when the motor 300 and inverter of the rotor 800 are cooled, the damper 100 can rotate toward the rotor 800 and guide the external airflow so that the air flowing to the area below the rotor 800 is guided into the interior of the boom 600 by the rotation of the rotor 800.

[0062] In addition, such as Figure 4 and Figure 5 As shown, when the battery 500 is cooled, the damper plate 100 can rotate in the opposite direction to the rotor 800 and guide the air flowing in front of the damper plate 100 through the inside of the boom 600 into the inside of the fixed wing 700 to cool the battery 500 located inside the fixed wing 700.

[0063] The air-mobile vehicle may also include: an airflow path 710 configured to guide air that has passed through damper 100 to battery 500; and multiple outlets 620 and 720 configured to exhaust air flowing into the air-mobile vehicle through damper 100 to the outside after cooling motor 300, inverter 400, or motor 300 and inverter 400 or battery 500.

[0064] When the damper plate 100 cools the battery 500, external air can flow into the interior of the boom 600 and the interior of the fixed wing 700, and an airflow path 710 can be formed inside the boom 600, which is configured to guide the flow of external air to allow air to flow into the interior of the boom 600 and into the interior of the fixed wing 700.

[0065] In addition, outlets 620 and 720 can be formed such that the air flowing into the interior of the airborne vehicle through the damper 100 is exhausted to the outside after cooling the motor 300, inverter 400, or motor 300 and inverter 400 or battery 500, to prevent the airborne vehicle from shaking due to the inflow of outside air into the airborne vehicle's fuselage.

[0066] Figure 6 This is a perspective view showing the closed opening 610 of the damper 100 of an airborne motor vehicle according to various exemplary embodiments of the present invention, and Figure 7 yes Figure 6 Cross-sectional view.

[0067] like Figure 6 and Figure 7 As shown, the damper 100 can cover the opening 610 in the initial state to prevent air flowing to the area below the rotor 800 from flowing into the interior of the air-mobile vehicle.

[0068] When the motor 300, inverter 400, or motor 300 and inverter 400, or battery 500 do not require cooling, the damper 100 remains in its initial state to cover the opening 610, so that outside air does not flow into the interior of the airborne motor vehicle.

[0069] Therefore, when in flight, air-mobile vehicles can fly effectively without external air flowing into their interior.

[0070] The air-mobile vehicle may also include a first temperature sensor 20 configured to measure the temperature of the motor 300 and the inverter 400, and a second temperature sensor 30 configured to measure the temperature of the battery 500, and the controller 10 may control the actuator 200 based on the temperature measured by the first temperature sensor 20 or the second temperature sensor 30.

[0071] The first temperature sensor 20 can measure the temperature of the motor 300 and inverter 400 of the rotor 800, the second temperature sensor 30 can measure the temperature of the battery 500, and the controller 10 can rotate the damper plate 100 based on the temperature of the motor 300 and inverter 400 or the temperature of the battery 500.

[0072] Therefore, by comparing the temperatures of the motor 300 and inverter 400 or the battery 500 with the corresponding reference temperatures, the damper plate 100 can be rotated effectively.

[0073] The controller 10 can control the actuator 200 such that when the temperature measured by the first temperature sensor 20 is equal to or greater than a first temperature, the air flowing to the area below the rotor 800 is guided through the damper plate 100 to the motor 300 and the inverter 400.

[0074] When the temperature measured by the first temperature sensor 20 is equal to or greater than the first temperature, the controller 10 can determine that the motor 300 and inverter 400 need to be cooled, and can control the actuator 200 to rotate the damper 100 toward the rotor 800.

[0075] Therefore, outside air can flow toward the motor 300 and the inverter 400 to cool them.

[0076] Therefore, the temperature rise of the motor 300 and the inverter 400 can be detected, and the damper plate 100 can be controlled in response to the temperature rise.

[0077] The controller 10 can control the actuator 200 so that when the temperature measured by the second temperature sensor 30 is equal to or greater than the second temperature, the air flowing to the area in front of the damper plate 100 is guided through the damper plate 100 to the battery 500.

[0078] When the temperature measured by the second temperature sensor 30 is equal to or greater than the second temperature, the controller 10 can determine that the battery 500 needs to be cooled and can control the actuator 200 to rotate the damper 100 in the opposite direction to the rotor 800.

[0079] Therefore, outside air can flow toward battery 500 to cool battery 500.

[0080] Because the temperatures required for cooling the motor 300 and inverter 400 and the temperatures required for cooling the battery 500 can be set to different temperatures, the first temperature and the second temperature can be set to different temperatures.

[0081] Furthermore, the controller 10 can control the operation of the actuator 200 by comparing a first difference and a second difference. The first difference is the difference between the temperature measured by the first temperature sensor 20 and a first temperature in a state where the temperature measured by the first temperature sensor 20 is equal to or greater than the first temperature. The second difference is the difference between the temperature measured by the second temperature sensor 30 and a second temperature in a state where the temperature measured by the second temperature sensor 30 is equal to or greater than the second temperature.

[0082] Therefore, the damper plate 100 can be controlled in an organized manner by detecting the temperature difference between the outside air temperature and the temperature of the motor 300 and the inverter 400, or the temperature difference between the outside air temperature and the temperature of the battery 500.

[0083] The controller 10 can control the actuator 200 such that when the temperature measured by the first temperature sensor 20 and the temperature measured by the second temperature sensor 30 are equal to or lower than a predetermined third temperature, the damper 100 covers the opening 610.

[0084] When the temperatures of the motor 300 and inverter 400 measured by the first temperature sensor 20 and the temperature measured by the second temperature sensor 30 are equal to or lower than a predetermined third temperature, it is not necessary to cool the motor 300, inverter 400, or motor 300 and inverter 400, or battery 500.

[0085] The predetermined third temperature can be set to a temperature lower than the first and second temperatures.

[0086] Therefore, the controller 10 can control the actuator 200 to make the damper 100 cover the opening 610 without rotating.

[0087] Therefore, when an airborne vehicle is in flight, external air flows along the outer surface of the boom 600, which can improve the energy efficiency of the airborne vehicle.

[0088] The controller 10 can control the actuator 200 so that when the air-mobile vehicle takes off or lands vertically, the air flowing to the area below the rotor 800 is guided by the damper 100 to the motor 300 and the inverter 400.

[0089] When an airborne vehicle takes off or lands vertically, the rotation speed of the rotor 800 increases, thus requiring cooling for the motor 300 and inverter 400 of each rotor 800.

[0090] In this configuration, the damper 100 can rotate toward the rotor 800, thereby guiding the flow of external air so that the air flowing into the area below the rotor 800 when the rotor 800 rotates flows into the interior of the air-mobile vehicle.

[0091] External air flowing into the cantilever 600 of the airborne vehicle through the damper 100 can cool the motor 300 and inverter 400 of the rotor 800, and is then discharged to the outside through the outlet 620.

[0092] Therefore, airborne mobile vehicles can take off and land vertically effectively.

[0093] The controller 10 can control the actuator 200 so that when the air-mobile vehicle is cruising, the air flowing in the area in front of the damper 100 is guided through the damper 100 to the battery 500.

[0094] When the air-mobile vehicle is cruising, the rotor speed of the rotor 800 decreases or the rotor 800 stops rotating, so there is no need to cool the motor 300 and inverter 400 of each rotor 800, but the battery 500 needs to be cooled.

[0095] In this configuration, the damper 100 can rotate in the opposite direction to the rotor 800, thereby guiding the flow of external air. This allows the air flowing into the area in front of the damper 100 to enter the interior of the airborne vehicle and be guided to the fixed wing 700 through the airflow path 710 to cool the battery 500. After cooling the battery 500, the external air can be discharged to the outside through the outlet 720.

[0096] The controller 10 can control the actuator 200 so that the damper 100 covers the opening 610 when the air-mobile vehicle is cruising.

[0097] When the battery 500 is adequately cooled or when cooling of the battery 500 is not required during the cruise of the airborne vehicle, the controller 10 can control the actuator 200 to cause the damper 100 to cover the opening 610 to maximize the aerodynamic performance of the airborne vehicle.

[0098] Therefore, air-mobile vehicles can fly effectively.

[0099] Multiple damper plates 100 can be configured, and actuators 200 can be connected to multiple damper plates 100 to rotate the damper plates 100 simultaneously.

[0100] like Figures 1 to 7 As shown, multiple damper plates 100 can be configured and can be applied to airborne motorized vehicles of various sizes.
