Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicle tools, and more particularly, to a multifunctional carrying device for a quadcopter unmanned aerial vehicle. Background Art

[0002] With the rapid development of technology, unmanned aerial vehicle (UAV) technology has become increasingly mature and demonstrated great application potential in many industries. In the field of surveying and mapping, UAVs can quickly obtain topographic data over large areas, improving the efficiency of surveying and mapping; in the agricultural field, UAVs are used for pesticide spraying and crop monitoring to achieve precision agriculture; in the logistics industry, UAV delivery provides an innovative solution to the "last mile" delivery problem; even in film shooting, UAVs equipped with professional camera equipment can capture unique perspective images with strong visual impact. Due to their flexibility, efficiency and other advantages, UAVs have gradually become an indispensable tool in various industries.

[0003] However, during the widespread application of UAVs, a series of problems have gradually emerged. On the one hand, portability is crucial for expanding the application scenarios of UAVs. In scenarios such as field operations and emergency rescue, staff need to frequently move the operation location, which requires UAVs and their related equipment to be easy to carry. Traditional UAV carrying methods are not only inconvenient but also may cause loss or damage due to scattered equipment, greatly restricting the rapid response ability and operation efficiency of UAVs.

[0004] On the other hand, the charging problem of UAVs troubles users in actual use. In the wild or in scenarios without fixed charging facilities, how to conveniently charge UAVs has become a major problem. Although some UAV backpacks have simple storage functions, they generally lack charging functions and cannot meet the user's need to charge at any time during movement, affecting the continuous operation ability of UAVs.

[0005] Particularly prominent is that in outdoor low-temperature environments, the performance of UAV lithium batteries is severely limited. The discharge capacity of lithium batteries decreases significantly as the temperature drops. When the ambient temperature is below a certain threshold, the internal resistance of the battery increases, the chemical reaction rate slows down, resulting in a reduction in the amount of electricity that the battery can release and unstable output voltage. This directly causes a significant reduction in the flight time of UAVs, making it impossible to complete the established tasks, and may even lead to UAV out-of-control crashes due to insufficient power, causing equipment losses and safety hazards.

[0006] Currently, the solutions to these problems have many deficiencies. Most existing heating devices are independent of UAV backpacks, are bulky and inconvenient to carry, and cannot be effectively combined with the charging process of UAVs; some heating methods are simple and crude, unable to precisely control the temperature, and may damage the battery. In terms of charging, there is a lack of an integrated and intelligent charging management system, which cannot simultaneously meet the fast charging needs of multiple UAVs and is also difficult to monitor the battery status in real time.

[0007] In summary, in the context of the continuous development of drone technology, how to achieve in - backpack charging of drones while ensuring portability and effectively solve the performance problems of lithium - ion batteries in low - temperature environments has become a key technical problem that urgently needs to be overcome in the drone field.

[0040] The multifunctional carrier for a quadrotor UAV provided by the technical solution of this application includes a canvas bag 1, an EVA inner lining, a metal lining plate 8, a heating system, a control box 10, a UAV charging cable, a carrier charging cable, and a spare parts box 4. Among them, the outside of the canvas bag is provided with double shoulder straps, a handle, and a zipper pocket. The EVA inner lining consists of an upper cover 2 and a lower cover 3 that open and close up and down. The lower cover 3 is provided with a plurality of countersinks for fixing the UAV. The shape and size of the countersinks are closely adapted to the UAV 7 in the folded state, which can effectively limit the shaking of the UAV 7 during transportation and protect the fuselage and rotors of the UAV 7 from damage. At the same time, the lower cover 3 is also provided with a wire routing groove for regularizing various cables, avoiding cable entanglement, and ensuring the safety and stability of the lines. The upper cover 2 is provided with independent countersinks for accommodating the spare parts box 4, the handheld ground station 5, and the spare battery 6 respectively. These countersinks can be designed according to the shape of the corresponding items, so as to provide a tight wrap and good buffer protection for the items, and thus prevent the items from being damaged by mutual collision during carrying. The metal lining plate 8 is fixed to the bottom of the EVA inner lining and is provided with mounting holes for installing the heating system and the control box 10. The surface of the metal lining plate 8 can be distributed with hollow areas to reduce weight and fix cables. The heating system includes a PTC fan heater array installed on the metal lining plate 8, an air duct 9 communicating with the inside of the carrier, and a temperature sensor. The air duct and the PTC fan heater cooperate to form a forced circulation air flow path. The control box 10 is fixed to one side of the metal lining plate 8 and is internally provided with a PCB control board 102. The outside can be provided with a charging socket, a power switch, a power indicator, and a communication interface. The PCB control board is connected to the heating system and the UAV charging cable through cables. The UAV charging cable is led out from the control box and branched to the tail interfaces of each UAV battery. The carrier charging cable can be a 24V power adapter, which can be stored in the outer zipper pocket of the canvas bag. The spare parts box 4 can be embedded in the countersink of the upper cover of the EVA inner lining and is used to store spare UAV propellers, fasteners required for installing the propellers, and screwdrivers.

[0041] The working principle of the carrying equipment in the present invention will be described below. First, the working principle of the heating system of the carrying equipment will be described. When in a low-temperature environment, the temperature sensor monitors the internal temperature of the carrying equipment in real time and transmits the temperature signal to the PCB control board in the control box. If the temperature is lower than the set threshold, the PCB control board issues an instruction to start the PTC fan heater array. The PTC fan heater array generates heat, and at the same time, the fan blows out hot air. The hot air passes through the air duct aligned with the air outlet of the PTC fan heater and, under the guidance of the air duct, flows inside the carrying equipment along the forced circulation air flow path. The hot air exchanges heat with the air and equipment inside the carrying equipment during the flow process to increase the internal temperature. The temperature sensor continuously monitors the temperature and feeds it back to the PCB control board. When the temperature reaches the set upper limit value, the PCB control board controls the PTC fan heater array to reduce power or stop working, thereby realizing the precise closed-loop control of the internal temperature of the carrying equipment and keeping equipment such as the UAV battery in a suitable working temperature range.

[0042] Next, the working principle of the charging system will be described. When in use, take out the charging cable (24V power adapter) of the carrying equipment from the outer zipper pocket of the canvas bag, connect it to an external power socket, and insert the other end into the charging socket of the control box. The PCB control board in the control box processes and distributes the input power. The UAV charging cable is led out from the control box, and its branched end is plugged and fixed to the tail interface of each UAV battery. The PCB control board controls the charging current and voltage through the charging management module according to the battery status (such as battery power, voltage, etc., obtained through the communication interface) to charge multiple UAV batteries simultaneously. The battery charge indicator shows the battery charging status in real time. During the charging process, the communication interface maintains data transmission with the battery and feeds back the battery status information in real time so that the PCB control board can adjust the charging strategy.

[0043] Through the PTC fan heater and the temperature control sensor, the technical solution of the present invention can realize the heating inside the carrying equipment, enable the temperature of the UAV battery itself to reach the ideal range in a low-temperature environment, effectively avoid problems such as the decline in battery performance and the abnormal startup of equipment caused by low temperature, ensure that the UAV can still operate normally under low-temperature conditions, and broaden the use environment range of the UAV. At the same time, the charging cables of multiple UAV batteries inside the carrying equipment are connected to the control board, which can charge multiple UAVs simultaneously, reduce the charging waiting time, and improve the charging efficiency. At the same time, it can realize the transmission of battery status information, facilitate the real-time grasp of battery status, such as parameters such as battery power, temperature, and voltage, and provide strong support for reasonably arranging the UAV use plan and ensuring flight safety.

[0044] Based on the above technical solutions, some more specific technical solutions are provided below and will be described separately.

[0045] In an alternative embodiment of the technical solution, the width of the double shoulder straps of the canvas bag is adapted to the curve of the human shoulder, and the handle is integrally and reinforcedly connected to the main body of the canvas bag.

[0046] Considering that in actual use, the carrying equipment often needs to be carried for a long time or moved frequently, the design of the canvas bag in this embodiment of the technical solution takes into account human comfort and structural firmness. The width of the double shoulder straps is adapted to the curve of the human shoulder, aiming to evenly distribute the weight on the shoulders during the carrying process of the user, reduce the local pressure on the shoulders, relieve shoulder fatigue, and improve the comfort of long-term carrying. The handle is integrally and reinforcedly connected to the main body of the canvas bag to ensure that when the carrying equipment is carried by hand, the connection between the handle and the bag body is strong enough to bear the weight of the equipment in the bag and prevent the handle from falling off during use, thus ensuring the safety of use.

[0047] In an alternative embodiment of the technical solution, the sink grooves of the EVA inner lining lower cover can be multiple rows of parallel grooves for fixing the fuselage and rotors of multiple drones in the folded state.

[0048] In actual use scenarios, such as field operations and emergency rescue, it is often necessary to carry multiple small quadrotor drones to meet different mission requirements. The purpose of the technical solution of this embodiment is to achieve stable storage of multiple drones in the folded state through the special sink groove structure of the EVA inner lining lower cover, avoid damage to the drones due to shaking and collision during transportation, and at the same time facilitate quick access and improve the operation efficiency.

[0049] Specifically, the sink grooves of the EVA inner lining lower cover can be a structure of multiple rows of parallel grooves. The number of grooves can be designed according to actual needs, such as 4 - 6 rows, to adapt to different carrying quantities. The width of the grooves matches the width of the fuselage of the drone in the folded state to ensure that the fuselage can be tightly embedded in the grooves. The depth of the grooves can be determined according to the height of the folded drone, and a margin of 1 - 2 cm can be reserved, so as to not only ensure the stable placement of the drone but also facilitate its removal. The length of the grooves needs to cover the overall length of the fuselage and rotors of the drone after folding, and extend appropriately by 1 - 3 cm at both ends to prevent the edges of the rotors from exceeding the grooves and being damaged. In summary, the structure of multiple rows of parallel grooves designed in this embodiment of the technical solution can provide a stable support and limiting structure for the drone. When the folded drone is placed in the grooves, the two sides of the fuselage are closely attached to the side walls of the grooves, and the width of the grooves restricts the lateral movement of the drone; the depth of the grooves positions the drone in the vertical direction to avoid up and down shaking; and the length of the grooves restricts the front and back movement of the drone.

[0050] In an alternative embodiment of the technical solution, the mounting holes of the metal lining plate can be circular through holes for fixing the PTC fan heater and the control box.

[0051] As a component for carrying the PTC heater and the control box, the purpose of the mounting holes on the metal lining is to provide a stable mounting foundation for these two components. In the technical solution of this embodiment, by using a specific type of mounting hole, namely circular through holes, to fix the PTC fan heater and the control box, it can ensure that during the operation of the carrying device, especially in the face of complex environments such as vibration and bumpiness, the PTC heater and the control box can maintain an accurate position and a stable state, avoiding affecting their normal operation due to displacement or loosening, and thus ensuring the reliable operation of the entire heating and charging system.

[0052] In an alternative embodiment of the technical solution, the air duct is in a long strip shape, arranged on the surface of the metal lining, and the air duct is opposite to the air outlet of the PTC fan heater, for guiding the airflow generated by the heating system to circulate inside the carrying device.

[0053] In a low-temperature environment, to ensure the normal operation of the lithium battery and other devices of a small quadcopter drone, it is necessary to heat them. The design purpose of the air duct in the technical solution of this embodiment is to cooperate with the PTC fan heater 12 to evenly and efficiently deliver the generated heat to all corners inside the carrying device, especially the area where the drone battery is placed, and at the same time form a closed circulation path, so that the hot air circulates continuously, maintaining a stable heating environment, avoiding local overheating or overcooling, and ensuring the stable performance of the device. Specifically, when the PTC fan heater 12 operates, the hot air blown out from the air outlet directly enters the diversion groove due to the alignment of the air duct with the air outlet. Under the guidance of the diversion groove, the hot air flows inside the carrying device along a preset path to form a circulation. During the circulation process, the hot air continuously exchanges heat with the surrounding air and devices, gradually increasing and maintaining the temperature evenly inside the carrying device. The temperature sensor monitors the internal temperature in real time and feeds the signal back to the PCB control board 102 in the control box 10. When the temperature reaches the set upper limit, the PCB control board 102 controls the PTC fan heater 12 to reduce the power or stop working; when the temperature is lower than the set lower limit, the PTC fan heater 12 increases the power to work, thereby achieving precise temperature control.

[0054] In an alternative embodiment of the technical solution, the control box is fixed to the metal lining by bolts, and its outer shell is provided with openings corresponding to the PCB control board, for exposing the charging socket, power switch, battery level indicator, and communication interface.

[0055] In this embodiment, the control box is bolted to the metal liner, ensuring that it remains securely in place even in complex environments, such as during bumpy and vibrating transportation. This prevents displacement or shaking from affecting the connection stability between the internal PCB control board and other components, thereby ensuring the normal operation of the entire charging and heating system. Furthermore, the housing is provided with openings corresponding to the PCB control board to expose the charging socket, power switch, battery indicator, and communication interface. The exposed charging socket facilitates user access to an external power source, providing a power input channel for charging the drone. The exposed power switch allows users to easily turn the control box on and off, thereby flexibly managing the operating status of the entire system. The exposed battery indicator intuitively displays the charging status of the drone battery, such as whether it is charging and the charging progress, allowing users to keep track of the battery level. The exposed communication interface facilitates data exchange between the control box and external devices, such as the drone battery and other monitoring equipment, enabling real-time transmission of battery status information.

[0056] In an optional embodiment, the spare parts box is provided with a special slot for drone blades, and a storage compartment for fasteners and screwdrivers.

[0057] In this embodiment, the spare parts box 4 can be equipped with dedicated slots for propellers and storage compartments for fasteners and screwdrivers. The slots can be designed based on the shape and size of the drone's propellers to fit snugly and securely, preventing damage from shaking or collisions during transport. The screwdriver storage compartment should be designed based on the length and thickness of the screwdriver, typically forming a groove to ensure a snug fit.

[0058] In an optional embodiment and technical solution, the upper cover and the lower cover of the EVA lining are fixed by Velcro at corresponding positions of the outer edge of the EVA lining and the inner wall of the canvas bag.

[0059] In the technical solution of this embodiment, the rough surface (or hook surface) of the Velcro can be sewn or pasted evenly along the edge contour on the outer edges of the upper cover and the lower cover of the EVA inner lining; the hook surface (or rough surface) of the Velcro is also accurately set at the corresponding positions on the inner wall of the canvas bag. In this way, when the EVA inner lining is placed in the canvas bag, the Velcro of the two can be accurately aligned and closely attached to form a stable fixing effect. This setting can not only ensure the stability of the inner lining in the canvas bag, but also effectively prevent the inner lining from shaking and shifting in the bag, thereby protecting the internal items such as drones and spare parts. At the same time, a zipper can be set at the circumferential edge position on the inner side of the upper cover of the EVA inner lining, so as to facilitate the use of mesh fabric to play a certain fixing role on the items placed in the upper cover of the EVA inner lining.

[0060] Obviously, the above-mentioned embodiments of the present invention are only examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
