Description

Technical Field

[0001] This invention belongs to the field of automated hangars, and in particular to a side-mounted multi-drone hangar system. Background Technology

[0002] With the rapid development of my country's national economy and the further acceleration of industrialization, drones are appearing more and more frequently in people's lives. Drones can be divided into military and civilian applications. In the military field, drones are divided into reconnaissance drones and target drones. In the civilian field, they are widely used in aerial photography, agriculture, plant protection, miniature selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying, news reporting, power line inspection, disaster relief, and film and television production. However, existing drone hangars have limited sortie capacity and intermittent operation. Their operation requires on-site power supply and loading / unloading facilities, which cannot meet the requirements for independent operation. This functional deficiency is particularly prominent under the current characteristics of clustered, centralized, and integrated operations.

[0003] The main drawbacks of current drone hangars are twofold:

[0004] 1. Continuous operation is difficult, especially due to the long interval between single-flight operations in the hangar. Current drone hangars, within standard container dimensions, cannot accommodate multiple drones and independent power supply units simultaneously, lacking continuous operational capability. Furthermore, the current direct-in / direct-out storage method in drone hangars occupies a significant amount of space, hindering space utilization and limiting the number of drones that can be stored. Additionally, the current use of non-independent drone units prevents them from independently executing entry and exit commands, making continuous collaborative operations difficult.

[0005] 2. Low level of integration and modularity, making it difficult to adapt to complex environments. Current drone hangars mostly require external power supply and cannot operate independently in complex environments; the transfer of drones in current hangars requires the assistance of hoisting equipment, and the transfer is limited by equipment conditions, making it difficult to achieve rapid transfer; current drone hangars adopt a shared structure, with each module restricting each other, resulting in a low level of integration and failing to meet the requirements for rapid modular maintenance. Summary of the Invention

[0006] The purpose of this invention is to provide a side-mounted multi-drone hangar system for drones, which is designed to meet the comprehensive performance requirements of drone clustering, centralization, and integration, including equipment power supply, task allocation, and continuous operation. The drone hangar can operate independently in any area that meets the terrain conditions, and can realize functions such as automatic take-off, operation, landing, recharging, control, and auxiliary loading and unloading.

[0007] The technical solution to achieve the purpose of this invention is as follows:

[0008] A side-deployed, multi-drone unmanned aerial vehicle (UAV) hangar system includes:

[0009] An unmanned aerial vehicle (UAV) system consists of multiple UAVs capable of performing different types of missions.

[0010] The main body of the drone housing is used to install the power unit, electronic control unit, and communication unit, and provides storage space for the drone system.

[0011] The power unit provides energy to the unmanned aerial vehicle system, the main body of the nest, the electronic control unit, and the communication unit.

[0012] The communication unit is capable of receiving flight mission commands and communicating with the unmanned aerial vehicle (UAV) system.

[0013] The electronic control unit is used for energy management of the power unit and task execution of the communication unit, and can control the operation of the main body of the nest according to the task instructions to realize the launch and recovery of the UAV system of the corresponding task type.

[0014] The drone is equipped with multiple legs and is capable of communicating with a communication unit;

[0015] The main body of the nest includes a structural frame and side extension units; the structural frame is provided with multiple side extension units; the side extension units include:

[0016] Side-extended fixed frame fixed to the structural frame;

[0017] The electronic control module is used to control the operation of the side extension lifting mechanism, the side extension folding mechanism, and the UAV lifting mechanism;

[0018] The side extension lifting mechanism is used to drive the side extension folding mechanism to slide up and down along the side extension fixed frame, providing height space for the take-off and landing of the UAV system; when the UAV takes off and lands, it drives the side extension folding mechanism to slide upward, and after the UAV completes take-off and landing, it drives the side extension folding mechanism to slide downward.

[0019] The side-extension folding mechanism is used to drive the self-returning landing pad to complete the horizontal and vertical rotation; when the self-returning landing pad is in a horizontal state, it serves as a platform for the drone to take off and land; when the self-returning landing pad is in a vertical state, there is a storage space for the drone between it and the side-extension fixed frame.

[0020] The self-returning landing pad adopts a concave structure, which can cooperate with the drone's outriggers to achieve self-returning of the drone after landing by gravity sliding; the lower part is equipped with multiple tube sleeves to cooperate with the drone's outriggers and to connect the drone's fastening mechanism.

[0021] The drone lifting mechanism is used to drive the drone fastening mechanism to move up and down along the sleeve, so as to realize the locking and releasing of the drone fastening mechanism and the drone legs.

[0022] The drone fastening mechanism is used to support the drone's outriggers, and to lock the outriggers in place when the drone descends and release them when it ascends.

[0023] The significant advantages of this invention compared to existing technologies are:

[0024] (1) Modular side-mounted units are used for launching, landing, and storing UAVs. The side-mounted unit consists of a side-mounted fixed frame, an electronic control module, a side-mounted lifting mechanism, a side-mounted folding mechanism, a self-returning landing pad, a UAV lifting mechanism, a UAV fastening mechanism, a side-mounted folding frame, and a battery holder. This allows each UAV to have an independent entry and exit channel, minimizes the impact between UAVs, and enables UAVs to take off and land independently or collaboratively, achieving continuous take-off and landing of UAV clusters and modular maintenance.

[0025] (2) Method for fixing and storing UAV outriggers after self-centering. The self-centering landing pad is fixed on the side-expanding and folding frame, and the lower part is fitted with the UAV fastening mechanism. The self-centering landing pad adopts a concave structure. When the UAV system lands, after the outriggers contact the self-centering landing pad, they slide along the concave surface towards the center of the self-centering landing pad under the action of gravity and fall into the UAV fastening mechanism. As the UAV lifting mechanism drives the bracket of the UAV fastening mechanism to move downward, the mechanical buckle tightens under the action of the sleeve, locking the outriggers. Conversely, as the UAV lifting mechanism drives the bracket of the UAV fastening mechanism to move upward, the mechanical buckle expands under the action of the sleeve, releasing the outriggers. This realizes the self-fixation of the UAV after self-centering and improves the UAV storage efficiency.

[0026] (3) The UAV hangar adopts a highly integrated modular design. The UAV hangar integrates a power unit, an electronic control unit, and a communication unit, and has independent power supply, communication, and maintenance capabilities. It is also equipped with an auxiliary loading and unloading mechanism, which can be used with dump trucks for self-loading, unloading, and transfer. The highly integrated modular design meets the requirements for continuous work and independent operation. At the same time, it expands the application scenarios of UAV hangars and broadens the operating range of UAVs.

[0027] (4) The UAV hangar adopts a cluster storage method. The UAV hangar stores multiple UAVs relatively independently and does not share the same access channels, so that the UAVs can be stored in a cluster, which improves the space utilization of the UAV hangar and reduces the take-off interval of the UAVs.

[0040] Combination Figures 1-11 This invention discloses a side-deployed multi-drone hangar system, comprising a drone system 1, a hangar body 2, a power unit 3, an electronic control unit 4, and a communication unit 5, as shown below. Figure 1 As shown. The unmanned aerial vehicle (UAV) system 1 is housed within the main body 2 of the nest, and the UAV system 1 is launched and retrieved through the main body 2. The main body 2 provides storage space for the UAV system 1, the power unit 3, the electronic control unit 4, and the communication unit 5, and is the main structural unit of this invention. The power unit 3 provides energy to the UAV system 1, the main body 2 of the nest, the electronic control unit 4, and the communication unit 5, and is located at the end of the main body 2. The electronic control unit 4 controls the launch and retrieval of the UAV system 1, the operation of the main body 2, the energy management of the power unit 3, and the task execution of the communication unit 5, and is located at the end of the main body 2. The communication unit 5 provides task allocation and communication for the UAV system 1 and is located at the end of the main body 2.

[0041] Unmanned aerial vehicle (UAV) system 1 consists of multiple UAVs capable of performing different types of missions. Each UAV comprises a main body 101, legs 102, arms 103, propellers 104, a battery 105, and a communicator 106. Figure 2As shown. The main body component 101 of the drone connects to the legs 102, arms 103, battery 105, and communicator 106, serving as the main structure for the drone system 1 to perform its tasks. The four legs 102 are located at the lower part of the main body component 101 and serve as supports and storage fixtures for the drone's launch and recovery in the drone system 1. The four arms 103 are respectively connected to the four propellers 104 and the main body component 101, and can be bent after the drone system 1 is recovered and unfolded before launch. The propellers 104 are connected to the arms 103 and serve as the flight power mechanism for the drone system 1, with a folding function. The battery 105 is inserted into the main body component 101 and provides energy for the drone system 1's flight, communication, and other functions; it is detachable and rechargeable. The communicator 106 is connected to the battery 105 and is located on the main body component 101, enabling communication with the communication unit 5.

[0042] The main body 2 of the nest consists of a structural frame 201, a side extension unit 202, and an auxiliary loading and unloading structure 203, as follows: Figure 3 As shown. The structural frame 201 provides support space for the power unit 3, the electronic control unit 4, and the communication unit 5. The side extension unit 202 and the auxiliary loading and unloading structure 203 are fixed on the structural frame 201. The structural frame 201 has symmetrically arranged multi-layer side extension units 202 on both sides. The side extension unit 202 is a modular unit and serves as the working mechanism for launching, recovering, and storing the UAV system 1. The auxiliary loading and unloading structure 203 is fixed to the end of the structural frame 201 and is used to assist the dump truck in loading and unloading. The dump truck's unloading arm hooks onto the auxiliary loading and unloading structure 203 and pushes the entire equipment off the truck.

[0043] Power unit 3 consists of generator set 301 and charging cabinet (302), such as Figure 4 As shown. The generator set 301 is connected to the electronic control unit 4 to provide power to the whole equipment; the charging cabinet (302) is connected to the electronic control unit 4 to charge the battery 105.

[0044] The electronic control unit 4 consists of a control system 401 and an operation display module 402, such as... Figure 5 As shown. The control system 401 is located in the space at the end of the structural frame 201 and is connected to the power unit 3, communication unit 5, side extension unit 202 and operation display module 402. The main body 2 of the control nest provides take-off, landing and storage services for the UAV system 1, and also converts and matches energy for the communication unit 5 and the charging cabinet (302). The operation display module 402 is connected to the control system 401 and displays the overall equipment status information (such as destination, distance, task type, execution time limit, etc.) and completes the input and detection of task instructions (such as destination coordinates, distance, transportation task, execution time limit).

[0045] Communication unit 5 consists of ground station 501 and antenna 502, such as Figure 6As shown. Ground station 501 is connected to electronic control unit 4 to receive power and simultaneously transmits take-off and landing commands to electronic control unit 4. Ground station 501 processes mission information and transmits flight mission commands to UAV system 1 and the outside world through antenna 502; antenna 502 is connected to ground station 501 to transmit information with UAV system 1.

[0046] The side deployment unit 202 consists of a side deployment fixed frame 20201, an electronic control module 20202, a side deployment lifting mechanism 20203, a side deployment folding mechanism 20204, a self-returning landing pad 20205, a UAV lifting mechanism 20206, a UAV fastening mechanism 20207, a side deployment folding frame 20208, and a battery holder 20209. Figure 7 As shown. The side-extension fixed frame 20201 is fixed inside the structural frame 201 and connected to the electronic control module 20202 and the side-extension lifting mechanism 20203. It serves as the installation interface for the side-extension unit 202 as a modular component. The electronic control module 20202 connects to the control system 401, the side-extension lifting mechanism 20203, the side-extension folding mechanism 20204, and the UAV lifting mechanism 20206. Its communication function matches the connecting components, serving as the communication interface for the side-extension unit 202 as a modular component. The side-extension lifting mechanism 20202... 0203 is fixed to the side extension fixed frame 20201 and connected to the side extension folding mechanism 20204. It adopts a motor-driven screw mechanism, which can drive the side extension folding mechanism 20204 to slide up and down along the side extension fixed frame 20201 to provide altitude space for the take-off and landing of the UAV system 1. One end of each of the two side extension folding mechanisms 20204 is fixed to the side extension lifting mechanism 20203 and can rise and fall together with the side extension lifting mechanism 20203. The other end is respectively hinged to the left and right sides of the side extension folding frame 20208. The system employs an electric lifting mechanism or an electric telescopic rod consisting of a motor, reducer, and lead screw. The left and right ends of the side-expanding and folding frame 20208 are rotatably connected to the lower end of the side-expanding and fixed frame 20201. The side-expanding and folding mechanism 20204 drives the side-expanding and folding frame 20208 to unfold and retract relative to the side-expanding and fixed frame 20201. When unfolded, it is in a horizontal position, providing a platform for drone launch or landing. When retracted, it is in a vertical position. A storage space for the drone is provided between the vertical position and the side-expanding and fixed frame 20201. The self-returning landing pad 20205 utilizes gravity sliding to allow the UAV system 1 to return to its original position after landing. The self-returning landing pad 20205 is fixed to the side-expanding and folding frame 20208. The lower part is equipped with a sleeve 2020501 for connecting the UAV fastening mechanism 20207. It consists of the sleeve 2020501, a fixed sealing skirt 2020502, and a concave self-returning landing pad surface 2020503. The surface of the landing pad surface 2020503 is coated with polytetrafluoroethylene (self-lubricating) material, such as... Figure 8The diagram shows the takeoff, landing, and storage components of the UAV system 1. The self-centering landing pad 20205 has a concave structure. The self-centering landing pad surface 2020503 has four concave surfaces, each with a landing hole for the UAV legs at its center. The sleeve 2020501 is installed inside the landing holes. When the UAV system 1 lands, the four legs 102 contact the self-centering landing pad 20205 and, under the influence of gravity, return to the center of the four concave surfaces, falling into the sleeve 2020501 and the UAV fastening mechanism 20207. The lifting mechanism 20206 is fixed on the side-expanding and folding frame 20208 and located inside the self-returning helipad 20205. It is connected to the drone fastening mechanism 20207, which can lift the drone system 1 during take-off and landing to meet the take-off, landing and storage conditions. It can adopt a motor + screw mechanism. The drone fastening mechanism 20207 consists of a bracket 2020702 and a mechanical buckle 2020701. One end of the drone fastening mechanism 20207 is connected to the drone lifting mechanism 20206, and the other end is in contact with the outrigger 102 of the drone system 1. One end of the bracket 2020702 is connected to the drone lifting mechanism 20206, and the other end is connected to four mechanical buckles 2020701. The sleeve 2020501 has a cross notch. The other end of the bracket 2020702 is an inner cylinder plus an outer ring structure. The outer ring is fitted on the outside of the sleeve 2020501, and the inner cylinder is located inside the sleeve 2020501 to support the drone legs. The inner cylinder and the outer ring are connected by a cross and nested with the sleeve with the cross notch. Four mechanical latches 2020701 are hinged to the bracket 2020702 and located inside the sleeve 2020501. When the drone descends, the drone legs 102 fall into the space between the four mechanical latches 2020701. The inner wall of the sleeve 2020501 has a structure with a larger upper opening and a smaller lower opening. During the descent of the bracket 2020702, the mechanical latches 2020701 are squeezed by the inner wall of the sleeve 2020501 and lock the drone legs 102. During the ascent, the inner wall of the sleeve releases the restriction on the mechanical latches 2020701 and releases the drone legs 102. The outer wall of the sleeve has a uniform diameter and can slide up and down along the bracket 2020702.

[0047] like Figure 9As shown, this is the mounting and securing component for the unmanned aerial vehicle (UAV) system 1. After landing, the outriggers 102 fall into the UAV fastening mechanism 20207. As the UAV lifting mechanism 20206 moves the bracket 2020702 downward, the mechanical latch 2020701 tightens under the action of the sleeve 2020501, locking the outriggers 102. Conversely, as the UAV lifting mechanism 20206 moves the bracket 2020702 upward, the mechanical latch 2020701 tightens under the action of the sleeve 2020501. 020701 expands and releases the outrigger 102; the side-expanding and folding frame 20208 is hinged on both sides at different positions on the side-expanding and folding mechanism 20204, which can realize the overall folding and unfolding and folding. At the same time, the upper end is equipped with a self-returning landing pad 20205, a drone lifting mechanism 20206 and a battery holder 20209; the battery holder 20209 is fixed on the side-expanding and folding frame 20208 and serves as a storage position for the battery 105. The battery holder 20209 has a battery position for installing a spare battery.

[0048] This invention has functions such as drone launch, continuous launch, landing, continuous landing, storage, and auxiliary transfer.
