Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of unmanned aerial vehicles, in particular to a multi-rotor unmanned aerial vehicle capable of quickly switching flight modes. BACKGROUND

[0002] With the continuous development of unmanned aerial vehicle technology, multi-rotor unmanned aerial vehicles have been widely used in many fields due to their flexible operation and wide application. Current multi-rotor unmanned aerial vehicles are mainly divided into free flight mode and tethered flight mode. In free flight mode, multi-rotor unmanned aerial vehicles usually rely on power batteries to provide power. However, due to the limitations of current battery density and stored power, the flight distance and duration of multi-rotor unmanned aerial vehicles are relatively short, which cannot meet the requirements of long-time space operation. In contrast, tethered flight mode provides power and communication for unmanned aerial vehicles through a tether, fundamentally solving the problem of limited battery power and short flight time of multi-rotor unmanned aerial vehicles, and theoretically achieving unlimited endurance and long-time space flight. However, the flight distance and height of tethered unmanned aerial vehicles are limited by the tether, and current tethered unmanned aerial vehicles are mostly hovering after taking off, which has a relatively single operation mode, such as providing lighting or serving as a communication antenna.

[0003] In the prior art, patent number 202221715398.3 discloses a technical solution for switching between free flight and tethered flight of an unmanned aerial vehicle by replacing batteries and related operations. Although this solution achieves the switching of flight modes to some extent, it still has some problems in actual application. In this solution, when switching from tethered mode to non-tethered mode, only a high-performance battery pack is simply installed on the top, and the onboard power supply and backup battery for tethered mode are not removed, which makes the onboard power supply and backup battery inside the cabin become dead weight in non-tethered mode, which is not conducive to fully utilizing the high-performance battery to achieve maximum endurance time, and also increases the weight of the unmanned aerial vehicle, resulting in increased flight energy consumption. In addition, the power module and battery module of the unmanned aerial vehicle are installed inside the unmanned aerial vehicle body. In tethered mode, the onboard power supply generates a large amount of heat, and the layout of the onboard power supply inside the cabin is not conducive to heat dissipation, which can easily cause the onboard power supply to have limited power due to high temperature. Therefore, there is an urgent need for a multi-rotor unmanned aerial vehicle capable of quickly switching flight modes and effectively solving the above problems. SUMMARY

[0021] Please refer to Figures 1 to 8 The present application provides a technical solution: a multi-rotor unmanned aerial vehicle capable of quickly switching flight modes, comprising a tethering component, an unmanned aerial vehicle 5, a tethering airborne power supply 6, the tethering component comprising a tethering box 1 and a tethering cable 2, one end of the tethering cable 2 being electrically connected to the tethering box 1, and the tethering cable 2 being electrically connected to the tethering airborne power supply 6, for providing power and communication signals for the unmanned aerial vehicle 5 in the tethering flight mode.

[0022] The unmanned aerial vehicle 5 comprises a body 501 and a body upper cover 502, the body upper cover 502 being hingedly mounted on the body 501, facilitating opening for installation and disassembly of internal components. The body 501 is provided with a left battery compartment 506, a middle compartment 508 and a right battery compartment 507, for installing different power modules. The body 501 is provided with an unmanned aerial vehicle battery socket 509 on the carbon fiber support frame on both sides of the middle compartment 508, for connecting a power battery 8 or the tethering airborne power supply 6, to provide power for the unmanned aerial vehicle 5.

[0023] The middle compartment 508 of the body 501 is provided with a fixing assembly for fixing the tethering airborne power supply 6, the tethering airborne power supply 6 being placed in the middle compartment 508 of the body 501, and the tethering airborne power supply 6 being detachably connected to the fixing assembly, and the tethering airborne power supply 6 being electrically connected to the unmanned aerial vehicle battery socket 509.

[0024] The body 501 is made of carbon fiber material and is provided with a support frame structure composed of carbon plates inside, having the advantages of light weight and high structural strength. The left battery compartment 506, the middle compartment 508 and the right battery compartment 507 are designed inside the body 501, for installing different power modules to meet the needs of different flight modes. The body upper cover 502 facilitates opening of the body 501 for installation and disassembly of internal parts, improving the convenience of maintenance and switching operation. The tethering airborne power supply 6 is used in the tethering flight mode, obtaining power from the tethering box 1 through the tethering cable 2, ensuring that the unmanned aerial vehicle can be suspended for a long time.

[0025] Specifically, the unmanned aerial vehicle 5 further comprises a landing gear 504 and a plurality of arms 503, each of which is detachably mounted on the periphery of the body 501, and the landing gear 504 is detachably mounted below the body 501.

[0026] The arm 503 is used to mount a rotor or other flight components to ensure the flight stability of the unmanned aerial vehicle. The detachable design facilitates transportation and storage. The landing gear 504 is used to support the stability of the unmanned aerial vehicle during parking and taking off on the ground, and to protect the unmanned aerial vehicle from ground impact.

[0027] Specifically, the fixing assembly comprises two limiters, which are respectively located on both sides of the middle cabin 508. The limiter comprises a fixed plate 510 and two index pins 511, the fixed plate 510 is fixedly installed with the body 501, and the two index pins 511 are respectively threadedly connected to the two end ears of the fixed plate 510. A plurality of lock ears 608 are fixedly connected on the side wall of the tethered airborne power supply 6, and the index pins 511 are limitingly inserted with the lock ears 608 after being rotated on the fixed plate 510.

[0028] The fixing assembly is used to fix the tethered airborne power supply 6. The lock ear 608 cooperates with the index pin 511 on the fixed plate 510 to realize the quick installation and disassembly of the tethered airborne power supply 6. A locking hole is formed in the center of the lock ear 608, and the index pin 511 is limitingly inserted with the locking hole of the lock ear 608, so as to realize the fixation of the tethered airborne power supply 6 and facilitate the disassembly.

[0029] Specifically, the bottom of the middle cabin 508 of the body 501 is provided with a square hole for ventilation and heat dissipation, and the tethered buckle mounting member 505 is fixedly installed below the body 501, which is used to connect with the tethering rope mounting buckle 3 in the tethering flight mode.

[0030] The square hole at the bottom of the middle cabin 508 ensures that the heat dissipation air duct of the tethered airborne power supply 6 is isolated from the internal space of the body, prevents dust from entering the internal space of the body, and provides sufficient space for heat dissipation, ensuring good heat dissipation effect.

[0031] Further specifically, the tethering component further comprises a tethering rope mounting buckle 3 and a tethering power supply plug 4, one end of the tethering cable 2 away from the tethering box 1 is electrically connected with the tethering power supply plug 4, and the tethering rope mounting buckle 3 is installed at one end of the tethering cable 2 close to the tethering power supply plug 4. The tethering rope mounting buckle 3 is detachably connected with the tethering buckle mounting member 505.

[0032] Wherein, the tether cable 2 is pulled out from the tether box 1, the tether rope hanging buckle 3 is installed at one end of the tether cable 2 close to the tether power plug 4, which is used to connect with the tether buckle hanging member 505 below the unmanned aerial vehicle 5, to ensure the stability of tether flight. The tether power plug 4 is plugged with the tether airborne power supply 6 (specifically with the airborne power socket 601 in the tether airborne power supply 6), to realize the electrical connection and ensure the stable power supply during tether flight.

[0033] Further specifically, the tether airborne power supply 6 is fixedly installed with the airborne power socket 601 below the body, and the bottom wall of the body of the tether airborne power supply 6 is respectively provided with a left side air inlet channel 605 and a right side air inlet channel 606, and the middle position of the bottom wall of the body of the tether airborne power supply 6 is provided with an air outlet, and the body of the tether airborne power supply 6 is fixedly installed with a heat dissipation fin 607 close to the air outlet. The airborne power socket 601, the left side air inlet channel 605, the air outlet and the right side air inlet channel 606 are all located at the square hole of the middle cabin 508, which ensures that the heat dissipation of the tether airborne power supply 6 is completely isolated from the machine body 501, and can prevent sand and dust from entering the machine body 501. The tether power plug 4 is plugged with the airborne power socket 601, and the two are electrically connected after plugging.

[0034] Wherein, when the tether airborne power supply 6 is installed into the middle cabin 508 of the multi-rotor unmanned aerial vehicle 5, the airborne power socket 601, the left side air inlet channel 605 and the right side air inlet channel 606 of the tether airborne power supply 6 are located at the square hole of the middle cabin 508, which facilitates the connection of the airborne power socket 601 and the tether power plug 4. The heat dissipation fin 607 realizes good heat dissipation effect through the left side air inlet channel 605 and the right side air inlet channel 606, avoids power drop caused by heating, and prolongs the service life of the unmanned aerial vehicle.

[0035] Specifically, the tether airborne power supply 6 is respectively electrically connected with a power supply plug I 602, a power supply plug II 603 and a backup battery docking plug 604, the unmanned aerial vehicle battery socket 509 is plugged with the power supply plug I 602 or the power supply plug II 603, and the unmanned aerial vehicle battery socket 509 is electrically connected with the power supply plug I 602 or the power supply plug II 603 after plugging, to provide power for the multi-rotor unmanned aerial vehicle 5.

[0036] Wherein, the tether airborne power supply 6 is used in tether flight mode, and obtains power from the tether box 1 through the tether cable 2, to ensure that the unmanned aerial vehicle can hover for a long time. The backup battery docking plug 604 is used to connect the backup battery 7, to provide emergency power supply for the unmanned aerial vehicle, and to ensure safe landing when the tether power supply fails.

[0037] Further specifically, the backup battery 7 is detachably installed in the left battery cabin 506 of the machine body 501. The plug of the backup battery 7 is plugged with the backup battery docking plug 604, and the two are electrically connected after plugging.

[0038] The backup battery 7 is used to provide backup power for the multi-rotor unmanned aerial vehicle 5 when the tethered box 1 fails to provide normal power supply for the multi-rotor unmanned aerial vehicle 5, so as to ensure that the multi-rotor unmanned aerial vehicle 5 can land smoothly. The backup battery 7 only needs to provide enough power for the multi-rotor unmanned aerial vehicle 5 to land in an emergency when the power supply is suddenly interrupted in the air, and therefore, the volume of the backup battery 7 is much smaller than that of the power battery 8. The backup battery 7 provides emergency power supply for the unmanned aerial vehicle, ensuring that the unmanned aerial vehicle can land safely when the tethered power supply fails.

[0039] Specifically, the power battery 8 is detachably installed in the left battery compartment 506 and the right battery compartment 507 of the body 501. The plug of the power battery 8 is plugged into and electrically connected with the unmanned aerial vehicle battery socket 509.

[0040] The power battery 8 provides power supply for the multi-rotor unmanned aerial vehicle 5 after the plug of the power battery 8 is connected with the unmanned aerial vehicle battery socket 509. The power battery 8 is used in the free flight mode to provide power supply for the unmanned aerial vehicle, and the plug of the power battery 8 is connected with the unmanned aerial vehicle battery socket 509 to ensure stable power supply.

[0041] In use: when the multi-rotor unmanned aerial vehicle 5 is in the free flight mode, only two power batteries 8 need to be installed, and the power battery 8 is connected with the unmanned aerial vehicle battery socket 509, so as to realize free flight. In the free flight mode, the unmanned aerial vehicle is powered by the power battery 8 carried by the unmanned aerial vehicle itself, and is not limited by external power supply, so that the unmanned aerial vehicle can flexibly perform various flight tasks, and is suitable for short-distance and short-time flight operation scenarios, such as aerial photography and inspection.

[0042] When it is necessary to switch to the tethered flight mode, the unmanned aerial vehicle 5 is first parked on the ground, and the two power batteries 8 are detached. Then, the tethered on-board power supply 6 is installed into the middle compartment 508 of the unmanned aerial vehicle 5. When the locking hole of the locking lug 608 and the central axis of the indexing pin 511 installed on the fixing plate 510 coincide, the indexing pin 511 is released to lock the tethered on-board power supply 6. Then, the power supply power plug I 602, the power supply power plug II 603 of the tethered on-board power supply 6 are connected with the unmanned aerial vehicle battery socket 509 to ensure stable power supply connection. The backup battery 7 is installed into the left battery compartment 506 of the unmanned aerial vehicle 5, and the plug of the backup battery 7 is connected with the backup battery docking plug 604 of the tethered on-board power supply 6 to provide additional safety protection for the unmanned aerial vehicle. Finally, the tethered cable 2 is pulled out of the tethered box 1, the tethered rope mounting buckle 3 is mounted into the tethered buckle mounting member 505 below the unmanned aerial vehicle 5, the tethered power supply plug 4 is connected with the on-board power supply socket 601 of the tethered on-board power supply 6, and the switching of the tethered flight mode is completed, so that the unmanned aerial vehicle can take off.

[0043] In the tethered flight mode, the UAV obtains stable power supply from the tethering box 1 through the tethering cable 2, which can theoretically achieve unlimited endurance and long-time empty flight, and is suitable for scenarios requiring long-time hovering, such as lighting and communication relay. Meanwhile, the heat dissipation design of the tethered airborne power supply 6 ensures stable operation of the power supply module during long-time work, avoiding power reduction caused by heating.

[0044] When it is necessary to switch back from the tethered flight mode to the free flight mode, first, disconnect the airborne power supply socket 601 and the tethering power supply plug 4, disconnect the tethering rope mounting buckle 3 and the tethering buckle mounting member 505, and disconnect the UAV 5 from the tethering box 1. Then, disconnect the power supply plug I 602, the power supply plug II 603 and the UAV battery socket 509, disconnect the backup battery docking plug 604 and the backup battery 7. After the indexing pin 511 is retracted, the tethered airborne power supply 6 can be dismounted. Take out the backup battery 7, install a power battery 8 in each of the left battery compartment 506 and the right battery compartment 507, connect the power battery 8 and the UAV battery socket 509, and complete the switching from the tethered flight mode to the free flight mode. The UAV can take off again.
