Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a nest for parking UAVs. Background Technology

[0002] With the rapid development of drone technology, drones are increasingly widely used in various fields such as aviation, agricultural plant protection, power line inspection, and logistics distribution. To achieve automated operation and management of drones, drone nests have emerged, serving as ground platforms that provide drones with automatic take-off and landing, charging, and maintenance functions. Currently, there are many types of drone nests on the market, with their door opening methods mainly including left-right opening, flip-top, and other complex opening methods. These designs have some shortcomings in practical applications, limiting the widespread application and development of drone nests. First, the left-right opening door design is similar to a traditional cabinet door, with the door divided into two parts in the middle, opening to the left and right sides respectively. This design requires the door to move to both sides when opening, occupying additional space, which can cause inconvenience in installation and use in environments with limited installation space. This is because the movement trajectory of this type of door during opening needs to avoid surrounding obstacles, and the space occupied is proportional to the door size. As the number of drone nests increases, this problem becomes increasingly apparent. Secondly, whether it's a left-right opening or flip-top door, the opening mechanism involves rotation or flipping motion, resulting in a complex mechanical structure and slow opening and closing speeds, impacting the scheduling efficiency of the drone. This is because the rotation or flipping mechanism needs to overcome significant inertia and gravity, requiring a considerable amount of time for the motor or drive unit to complete the opening action. Furthermore, mechanical friction and resistance during the opening process also prolong the opening time. Finally, components such as the hinges of left-right opening doors and the support bars of flip-top doors are prone to wear, deformation, and even failure during frequent opening and closing, affecting the normal use of the doors. This is because the rotation and flipping motion of the doors relies on multiple moving parts. These parts, under repeated mechanical stress and environmental factors (such as wind, rain, and temperature changes), are prone to aging, loosening, or damage, increasing maintenance costs and the risk of failure. Utility Model Content

[0003] In order to address the technical problems existing in the prior art to a certain extent, this utility model provides a nest for parking drones, which uses linear motion to open and close the hatch, simplifying the movement structure of the nest hatch and ensuring that the drone nest hatch can be opened and closed quickly and stably. This solves the problems of large space occupation, slow opening and closing speed, and easy structural damage in the existing nest hatch opening and closing methods.

[0004] This utility model discloses a drone housing, comprising: a cabin assembly having an internal space for accommodating the drone, and a door opening on the top of the cabin assembly; a movable door for closing the door opening, the movable door opening being opened or closed by linear reciprocating motion on the cabin assembly; a drive mechanism connected to the movable door, driving the movable door to linear reciprocating motion; and a guide mechanism disposed on the cabin assembly and slidingly engaging with the movable door to guide the linear motion of the movable door.

[0005] According to the present invention, a nest for parking unmanned aerial vehicles (UAVs) includes a drive mechanism comprising: a motor with a power output shaft; an output gear coaxially sleeved on the power output shaft of the motor; and a rack extending along the linear movement direction of the movable door and fixed to the movable door. The rack and the output gear mesh with each other to drive the rack and the movable door through the motor.

[0006] According to the present invention, a nest for parking unmanned aerial vehicles (UAVs) is provided, wherein the motor is a dual-output-shaft motor; there are two output gears and two racks; the two output gears are coaxially sleeved on the output shafts at both ends of the dual-output-shaft motor; the two racks are fixed on opposite sides of the movable hatch and mesh with each of the output gears.

[0007] According to the present invention, a nest for parking unmanned aerial vehicles (UAVs) includes a guiding mechanism comprising three guide rails. The outer and inner rails of the three guide rails are respectively fixedly mounted on the cabin assembly and the movable hatch. The movable hatch is guided to reciprocate linearly on the cabin assembly by the linear sliding of the middle rail of the three guide rails between the outer and inner rails.

[0008] According to the present invention, a nest for parking unmanned aerial vehicles is provided with a sealing strip at the joint between the movable hatch and the hatch opening.

[0009] According to the present invention, a nest for parking unmanned aerial vehicles (UAVs) is provided in the cabin assembly, wherein a centering platform for parking the UAVs is provided in the centering platform, and a pushing mechanism is movably provided on the centering platform, thereby pushing the UAVs to the center position of the centering platform.

[0010] According to the present invention, a drone nest for parking drones includes a pushing mechanism comprising: movable push plates, wherein the number of movable push plates is at least four, and each movable push plate can be translatably arranged around the centering platform; the drone is driven to move to the center position of the centering platform by the movable push plates moving towards the center of the centering platform.

[0011] According to the present invention, a drone nest is provided with at least one of the movable push plates, which is equipped with a first sensor for detecting drones; the first sensor is located in the middle of the movable push plate, and feeds back the detection signal of the drone to the control system of the nest through the first sensor.

[0012] According to the present invention, a drone nest for parking drones includes a pushing mechanism that further comprises a first annular conveyor belt and a second annular conveyor belt. The first and second annular conveyor belts are distributed on adjacent sides of the centering platform. The upper and lower conveyor sections of the first annular conveyor belt are respectively provided with a first upper transmission block and a first lower transmission block. Two parallel movable push plates are respectively driven to the first upper transmission block and the first lower transmission block, and the forward and reverse rotation of the first annular conveyor belt causes the first upper transmission block and the first lower transmission block to move closer to each other and further away from each other. The upper and lower conveyor sections of the second annular conveyor belt are respectively provided with a second upper transmission block and a second lower transmission block. Two parallel movable push plates are respectively driven to the second upper transmission block and the second lower transmission block, and the forward and reverse rotation of the second annular conveyor belt causes the second upper transmission block and the second lower transmission block to move closer to each other and further away from each other.

[0013] According to the present invention, a nest for parking unmanned aerial vehicles (UAVs) includes a second sensor on the cabin assembly. When the movable door closes the door opening, the movable door approaches or contacts the second sensor to provide a detection signal indicating that the movable door is closed to the nest's control system via the second sensor. When the movable door opens the door opening, the movable door moves away from the second sensor to provide a detection signal indicating that the movable door is open to the nest's control system via the second sensor.

[0014] This utility model discloses a drone nest for parking unmanned aerial vehicles (UAVs). Its structure includes a cabin assembly, a movable door, a drive mechanism, and a guide mechanism. The cabin assembly is the main body of the UAV nest, forming an internal space to accommodate the UAV and featuring a door opening at its top. It forms the foundation of the entire nest structure, providing parking space for the UAV and serving as a carrier for the installation and operation of other components. The movable door is used to close the door opening; its movement involves linear reciprocating motion on the cabin assembly to open or close the door, protecting the UAV inside. The drive mechanism is connected to the movable door and drives it in linear reciprocating motion. The drive mechanism is the power source for the movable door's movement, working closely with the door to convert power into linear motion. The guide mechanism is mounted on the cabin assembly and slides with the movable door, guiding its linear movement. The guide mechanism ensures that the movable door follows a predetermined linear trajectory during movement, guaranteeing the accuracy and stability of the door's movement. During operation, when the hatch needs to be opened, the drive mechanism activates, generating power. Since the drive mechanism is connected to the movable hatch via a transmission, the power is transmitted to the hatch. Simultaneously, the guide mechanism slides against the hatch on the nacelle assembly, ensuring that the hatch smoothly opens along a straight trajectory under the power of the drive mechanism. When the hatch needs to be closed, the drive mechanism reverses its operation, again driving the hatch to move in a straight line towards the closing direction via the transmission connection. Guided by the guide mechanism, the hatch accurately closes the opening. Because the hatch uses linear reciprocating motion, compared to traditional left-right opening or flip-top hatches, it does not require additional space on the sides or top. In environments with limited space for hatch installation, this linear motion hatch utilizes space more effectively, facilitating the installation and use of the nacelle. Furthermore, the linear motion hatch structure is relatively simple; the drive mechanism can directly drive the hatch in a linear motion without complex rotation or flipping actions. Compared to rotating or flipping mechanisms that require overcoming significant inertia and gravity, linear motion hatches can open and close much faster, improving the efficiency of UAVs entering and exiting the nest and facilitating rapid UAV scheduling. Furthermore, the guiding mechanism ensures the stability of the hatch during linear motion, reducing wear and deformation caused by uneven force or deviation from the track. Simultaneously, linear motion hatches reduce reliance on vulnerable components such as hinges, lowering the risk of component damage from frequent opening and closing, thereby improving the overall structural stability of the nest and reducing maintenance costs and failure risks.

[0035] like Figures 1 to 9 As shown, a drone housing according to this embodiment includes a cabin assembly 100, a movable door 200, a drive mechanism 300, and a guide mechanism 400. The cabin assembly 100 forms a space for accommodating the drone. A door opening 101 is provided on the top of the cabin assembly 100. The movable door 200 is used to close the door opening 101. The movable door 200 opens or closes the door opening 101 by linear reciprocating motion on the cabin assembly 100. The drive mechanism 300 is connected to the movable door 200 and drives the movable door 200 to reciprocate linearly. The guide mechanism 400 is installed on the cabin assembly 100 and slides with the movable door 200 to guide the linear motion of the movable door 200.

[0036] It is understood that the nest structure of this embodiment includes a cabin assembly 100, a movable hatch 200, a drive mechanism 300, and a guide mechanism 400. The cabin assembly 100 is the main body of the UAV nest, forming a space to accommodate the UAV, and has a hatch opening 101 on its top. It is the foundation of the entire nest structure, providing space for the UAV to park, and also serves as a carrier for the installation and operation of other components. The movable hatch 200 is used to close the hatch opening 101. Its movement is achieved by linear reciprocating motion on the cabin assembly 100 to open or close the hatch, and its function is to protect the UAV inside the cabin. The drive mechanism 300 is connected to the movable hatch 200 through transmission, and drives the movable hatch 200 to perform linear reciprocating motion through its own operation. The drive mechanism is the power source for the movement of the movable hatch. It works closely with the hatch to convert power into linear motion of the hatch. The guide mechanism 400 is mounted on the cabin assembly 100 and slides with the movable hatch 200 to guide its linear movement. The guide mechanism ensures that the hatch moves along a predetermined straight trajectory, guaranteeing the accuracy and stability of the hatch movement. During operation, when the hatch needs to be opened, the drive mechanism 300 is activated, generating power. Since the drive mechanism 300 is connected to the movable hatch 200, the power is transmitted to the hatch. Simultaneously, the guide mechanism 400 slides with the hatch 200 on the cabin assembly 100, ensuring that the hatch 200 smoothly opens the hatch opening 101 along a straight trajectory under the power of the drive mechanism 300. When the hatch needs to be closed, the drive mechanism 300 reverses its operation, again driving the movable hatch 200 to move in a straight line towards the closing direction via the transmission connection. Guided by the guide mechanism 400, the movable hatch 200 accurately closes the hatch opening 101. Because the hatch uses linear reciprocating motion, compared to traditional left-right opening or flip-top hatches, it does not require additional space on the sides or top. In environments with limited space for drone installation, this linear motion hatch can utilize space more effectively, facilitating the installation and use of the drone nest. Furthermore, the linear motion hatch structure is relatively simple; the drive mechanism can directly drive the hatch in a linear motion without complex rotation or flipping actions. Compared to rotation or flipping mechanisms that need to overcome significant inertia and gravity, the linear motion hatch can complete opening and closing actions more quickly, improving the efficiency of drones entering and exiting the nest and facilitating rapid drone scheduling. Moreover, the guide mechanism ensures the stability of the hatch during linear motion, reducing wear and deformation caused by uneven force or deviation from the track during movement. Meanwhile, the linear motion of the hatch reduces reliance on vulnerable components such as hinges, lowering the risk of component damage due to frequent opening and closing, thereby improving the overall structural stability of the nest and reducing maintenance costs and failure risks.

[0037] In one embodiment, the drive mechanism 300 comprises a motor 301, an output gear 302, and a rack 303. The motor 301 is equipped with a power output shaft, which serves as the starting point for power transmission. The output gear 302 is coaxially mounted on the power output shaft of the motor 301, ensuring that the motor 301 can effectively transmit power to the output gear 302. The rack 303 extends along the linear direction of movement of the movable door 200 and is securely fixed to the movable door 200. During the operation of the drive mechanism 300, the rack 303 and the output gear 302 engage with each other. When the movable door 200 of the hive needs to be opened or closed, the motor 301 starts, and the power output shaft of the motor 301 begins to rotate, driving the connected output gear 302 to rotate synchronously. Due to the meshing relationship between the rack 303 and the output gear 302, the rotation of the output gear 302 is converted into the linear motion of the rack 303, which in turn drives the movable hatch 200, on which the rack 303 is fixed, to move along a predetermined linear trajectory, thus realizing the linear reciprocating opening and closing operation of the hatch door. It can be understood that in the above structure, the motor 301 acts as a power source, driving the output gear 302 to rotate via a power output shaft. The output gear 302 meshes with the rack 303 fixed on the movable hatch 200. When the output gear rotates, the rack is subjected to the pushing and pulling force of the meshing gear, realizing the movement of the movable hatch 200 along the linear direction defined by the guide mechanism. Changes in motor speed and direction can be directly transmitted to the movable hatch 200 through the gear-rack transmission mechanism to realize the opening or closing of the hatch. The gear and rack meshing transmission scheme can achieve high transmission efficiency and linear accuracy, thereby realizing smooth, linear, and controllable opening and closing of the hatch. Due to the clear and simple transmission path, intermediate links are reduced, resulting in a compact structure, lower maintenance costs, and improved reliability. High-precision linear motion control is beneficial to improving the efficiency and safety of UAVs entering and exiting the hive. Specifically, in this embodiment, motor 301 is a dual-output-shaft motor. In this hive, there are two output gears 302 and two racks 303. The two output gears 302 are coaxially connected to the output shafts at both ends of the dual-output-shaft motor, while the two racks 303 are fixed on opposite sides of the movable hatch 200 and mesh with their respective output gears 302. By simultaneously outputting power from both ends of the dual-output-shaft motor, and through the meshing transmission of the two output gears 302 and two racks 303, the movable hatch 200 can be subjected to more even force during linear motion, ensuring the smoothness and accuracy of the hatch opening and closing action, and improving the overall reliability and practicality of the hive.It is understandable that the dual-output shaft motor simultaneously outputs power to two symmetrically arranged gear-rack sets. The two racks are symmetrically distributed on the left and right sides or front and rear sides of the movable hatch 200. When the motor operates, the two output shafts drive the output gears on both sides to rotate synchronously, and the spur racks 303 on both sides are subjected to synchronous force, thus ensuring that the movable hatch maintains a stable posture in the track and preventing hatch jamming or tilting caused by uneven force on one side. Through the dual-output shaft motor and the symmetrically distributed gear-rack transmission, the opening and closing force of the hatch is evenly transmitted from both sides, ensuring hatch stability and operational accuracy. On the one hand, the synchronous transmission on both sides effectively prevents the movable hatch from tilting during movement, improving the straightness and positioning accuracy of the hatch movement. On the other hand, it reduces wear and failure rate caused by force on one side, extending the service life of components. Furthermore, it improves the reliability and efficiency of hatch opening and closing, which is particularly effective in large-size hatch scenarios.

[0038] In one embodiment, the guide mechanism 400 includes a three-section guide rail 401. Specifically, the outer and inner rails of the three-section guide rail 401 are fixedly mounted on the cabin assembly 100 and the movable door 200, respectively. The middle rail of the three-section guide rail 401 slides linearly between the outer and inner rails, thereby guiding the movable door 200 to achieve linear reciprocating motion on the cabin assembly 100. The structure of the three-section guide rail is similar to a high-precision telescopic linear guide rail. It achieves a longer linear telescopic stroke within a limited installation space through a combination of three nested rails (outer rail-middle rail-inner rail). When the movable door opens or closes, the middle rail slides within the outer rail, and the inner rail slides within the middle rail, thereby providing smooth and high-precision linear guidance for the movable door (200). This reduces the swaying and instability of the door in the horizontal or vertical direction, ensuring that the door moves smoothly back and forth along a fixed path. In other words, the three-section guide rail structure ensures a large and precise guiding stroke in a limited space, making the movable hatch more stable and smooth in linear movement. On the one hand, the multiple support of the three-section guide rail improves the stability and controllability of the hatch movement; on the other hand, it can achieve a longer stroke with a shorter installation length, improving space utilization; and furthermore, it can reduce vibration and noise during movement and extend the service life of the guide components.

[0039] In one embodiment, a sealing strip 102 is provided at the mating point between the movable hatch 200 and the hatch opening 101. It is understood that the sealing strip 102 effectively fills the gap between the movable hatch 200 and the hatch opening 101. When the movable hatch 200 is closed, the sealing strip 102 fits tightly against the edge of the opening of the cabin assembly 100, providing a seal and preventing dust, moisture, and other impurities from entering the cabin. This helps protect the drone and other equipment inside the cabin from external environmental factors, ensuring a clean and dry internal environment, thereby guaranteeing the normal operation and lifespan of the cabin and its internal equipment. In other words, improving the protective performance of the internal environment of the cabin when the hatch is closed ensures the safe and reliable operation of the drone and its internal electronic devices. On the one hand, it improves the sealing performance of the cabin environment, reducing the impact of the external environment on the internal electronic equipment; on the other hand, it extends the lifespan of the internal equipment, reduces maintenance costs; and thirdly, it ensures the environmental stability of the drone during storage, standby, and maintenance.

[0040] In one embodiment, a centering platform 500 for parking drones is provided within the cabin assembly 100. A pushing mechanism is movably mounted on the centering platform 500. When a drone lands in the nest, the pushing mechanism can move the drone to the center position of the centering platform 500. It is understood that in actual use, the drone may land on the surface of the centering platform 500, but its position may not be exactly in the center. The pushing mechanism, through active movement, moves the drone from the off-center position to the center, improving the drone's positioning accuracy and facilitating subsequent charging, maintenance operations, or stability during re-takeoff. This structure achieves drone positioning through mechanical action, significantly reducing the accuracy requirements for landing and improving the fault tolerance of the nest system. In other words, this structure enables automatic positioning and centering of the drone within the nest, improving the accuracy and efficiency of the drone-nest docking process. This allows the drone to be accurately positioned in a designated location within the cabin, reducing the workload and time required for manual adjustments. This helps improve the reliability and safety of the drone during parking, charging, data transmission, and re-takeoff, and also enhances the automation and adaptability of the nest.

[0041] Regarding the specific structure of the pushing mechanism, it includes four movable push plates 600, each capable of translating and surrounding the centering platform 500. By moving these movable push plates 600 towards the center of the centering platform 500, the drone is propelled from all four sides to the center position. Multiple push plates push the drone from different directions, facilitating its centering on the platform. During operation, as the drone lands on the platform, the push plates 600 simultaneously or sequentially retract, bringing the drone closer to the center. The combined thrust from four directions ensures precise positioning of the drone within the plane, preventing deviations that might occur with unidirectional or bidirectional pushing. The push plates are controlled synchronously or sequentially, combined with sensor feedback, to achieve precise centering of the drone. This structure enables simultaneous multi-directional positioning correction, improving centering efficiency, and allows for drone positioning without additional auxiliary structures or manual intervention, enhancing the automation of the drone nest. Specifically, at least one movable push plate 600 is equipped with a first sensor 601 for detecting the UAV. The first sensor 601 is located in the middle of the movable push plate 600, and its function is to feed back the detection signal of the UAV to the control system of the nest. It can be understood that during the operation of the nest, when the movable push plate 600 performs a centering operation on the UAV, the first sensor 601 can sense the positional relationship between the UAV and the push plate (e.g., infrared, proximity sensing, pressure sensing), and transmit the detection signal to the control system. The control system can then determine whether the UAV has been centered or whether further fine-tuning is needed, realizing dynamic closed-loop control of the centering process (i.e., "detection-feedback-adjustment"). Specifically, when the UAV lands in the cabin and needs to perform a centering operation, the movable push plate 600 used for centering and positioning moves towards the UAV, contacting and pushing the UAV along the direction of the centering platform 500. Since the first sensor 601 is located in the middle of the movable pusher 600, when the drone is continuously pushed by the movable pusher and gradually moves towards the center of the centering platform, once the drone reaches the center of the platform, the first sensor 601 can detect its presence. After detecting that the drone is in the center of the platform, the first sensor 601 feeds a signal back to the control system of the drone nest. Based on this signal, the control system determines that the drone has been successfully pushed to the center of the centering platform, achieving precise centering and positioning of the drone. At the same time, the control system can instruct the movable pusher to stop pushing, avoiding excessive pushing or damage to the drone.

[0042] In one embodiment, the pushing mechanism further includes a first annular conveyor belt 501 and a second annular conveyor belt 502. The first annular conveyor belt 501 and the second annular conveyor belt 502 are distributed on adjacent sides of the centering platform 500. The upper and lower conveying sections of the first annular conveyor belt 501 are respectively provided with a first upper drive block 503 and a first lower drive block 504. Two parallel movable push plates 600 are respectively driven to the first upper drive block 503 and the first lower drive block 504. By rotating the first annular conveyor belt 501 forward and backward, the first upper drive block 503 and the first lower drive block 504 can be moved closer together and further apart. The upper and lower conveying sections of the second annular conveyor belt 502 are respectively provided with a second upper drive block 505 and a second lower drive block 506. Two more parallel movable push plates 600 are respectively driven to the second upper drive block 505 and the second lower drive block 506. By rotating the second annular conveyor belt 502 forward and backward, the second upper drive block 505 and the second lower drive block 506 can be moved closer together and further apart. During operation, when the annular conveyor belt rotates clockwise, each transmission block moves accordingly, causing the connected movable push plates to move towards or away from the center. Taking the first annular conveyor belt 501 as an example, both its upper and lower transmission sections move clockwise. Since the first upper transmission block 503 is connected to the upper transmission section and the first lower transmission block 504 is connected to the lower transmission section, during clockwise rotation, the first upper transmission block 503 and the first lower transmission block 504 will move in the same direction along with their respective connected transmission sections, causing them to move away from each other. Similarly, when the second annular conveyor belt 502 rotates clockwise, the second upper transmission block 505 and the second lower transmission block 506 will also move away from each other. When the first annular conveyor belt 501 rotates counterclockwise, both its upper and lower transmission sections move counterclockwise. The first upper transmission block 503 and the first lower transmission block 504 will move in the same direction along with their respective connected transmission sections, causing them to move closer together. Similarly, when the second annular conveyor belt 502 rotates counterclockwise, the second upper transmission block 505 and the second lower transmission block 506 will also move closer to each other. Since the ends of the four movable push plates 600 are respectively connected to the first upper transmission block 503, the first lower transmission block (504), the second upper transmission block 505, and the second lower transmission block 506, in actual use, in the initial state, the four movable push plates 600 are located around the centering platform 500, waiting for the drone to land. When the drone lands on the centering platform 500, it needs to be moved to the center of the platform, and the rotation direction of the annular conveyor belts (501, 502) is controlled according to the position of the drone on the platform.For example, if the drone deviates to one side of the centering platform 500, the corresponding circular conveyor belt will activate. Taking the first circular conveyor belt 501 as an example, if it rotates counterclockwise, the first upper transmission block 503 and the first lower transmission block 504 will move closer together, driving the connected movable push plate 600 to move towards the center, thereby pushing the drone towards the center of the centering platform 500. Similarly, if the drone deviates in another direction, the second circular conveyor belt 502 will rotate clockwise or counterclockwise as needed, causing the second upper transmission block 505 and the second lower transmission block 506 to drive the corresponding movable push plate 600 to move, pushing the drone towards the center from another direction. In actual operation, by precisely controlling the clockwise and counterclockwise rotation of the first circular conveyor belt 501 and the second circular conveyor belt 502, the movable push plates 600 in all four directions can work together. Regardless of the initial position of the drone on the centering platform 500, the four movable push plates 600 can apply thrust to the drone from different directions, gradually moving it to the center position of the centering platform 500, ultimately achieving the centering operation of the drone. In summary, the above structure enables the reversible and controllable movement of the movable push plate on the centering platform through the ring conveyor belt structure, which facilitates precise adjustment of the push plate position, simplifies the complexity brought about by traditional mechanical multi-link linkage, improves the consistency and synchronization of the push plate movement, and further ensures the speed of UAV positioning.

[0043] In one embodiment, a second sensor 103 is installed on the nacelle assembly 100. When the movable door 200 closes the door opening 101, the movable door 200 approaches or contacts the second sensor 103. At this time, the second sensor 103 will send a detection signal to the nacelle control system indicating that the movable door 200 is closed. Conversely, when the movable door 200 opens the door opening 101, the movable door 200 moves away from the second sensor 103, and the second sensor 103 sends a detection signal to the nacelle control system indicating that the movable door 200 is open. It can be understood that when the door 200 moves in the closing direction and reaches a fully closed position, the second sensor 103 senses that the door has reached a predetermined reference position, sends a closing completion signal to the control system, and the motor stops rotating to ensure sealing and safety. Conversely, when the door moves in the opening direction and moves away from the position of the second sensor 103, the sensor signal changes, indicating to the control system that the door has been opened to a specified extent. By using position detection sensors to ensure precise control and monitoring of the hatch opening and closing positions, this solution prevents mechanical overload or poor sealing caused by improper hatch travel. It provides accurate information on the hatch opening and closing status, which is beneficial for the control system to perform closed-loop control of the hatch movement, avoid damage to components due to excessive opening and closing, ensure the sealing and safety of the hatch when closed, and ensure positioning and operational safety when opening. In combination with the control logic of the main control box, it can help to achieve automated hatch management and improve the intelligence level of the entire nest operation.

[0044] Optionally, the second sensor 103 can be of various types, such as a contact limit switch that can provide a door-closing signal when the movable door 200 touches it; a micro switch can also be used, which changes the circuit on / off state by touching the door to transmit the door status. Non-contact sensors include Hall effect sensors, which use the change in magnetic field generated by the magnetic material of the door to detect voltage changes; photoelectric sensors, which determine the door status by whether a light beam is blocked; and ultrasonic sensors, which rely on the ultrasonic wave reflection time to determine the door position and then provide a signal indicating whether the door is open or closed.

[0045] In addition, rack fixing plates 201 are fixedly connected to the left and right sides of the movable hatch, and the straight racks 303 on the left and right sides are fixed on the rack fixing plates 201 respectively.

[0046] The cabin assembly 100 also includes a bottom shell 104, within which the centering platform 500 is installed. Guide rail fixing plates 105 are fixed to the left and right sides of the bottom shell 104, respectively. The outer rails of two three-section guide rails 401 are fixedly connected to the guide rail fixing plates 105 on the left and right sides. A front baffle 106 and a rear baffle 107 are installed on the front and rear sides of the bottom shell 104, respectively. The front baffle 106 and rear baffle 107 are also located on the front and rear sides of the centering platform 500, thus obstructing the front and rear sides of the UAV. A cooling assembly 110 is installed inside the bottom shell 104 of the cabin assembly 100 to facilitate heat dissipation from the interior of the cabin. Two antennas 111 are also installed on the front of the cabin assembly 100. The antennas 111 are used to receive and transmit wireless signals, ensuring normal communication between the cabin and external equipment. For example, it receives control signals from the remote controller, enabling operators to remotely control some functions of the nest; simultaneously, it sends relevant information about the nest and the drone, such as status information and data acquisition results, to the ground control station, ensuring smooth information exchange between the nest and external devices. This facilitates remote control and data transmission of the nest, improving the efficiency and safety of drone operations. The cabin assembly 100 also houses an RTK antenna 112, which is primarily used in the drone nest system to acquire high-precision positioning signals. The cabin assembly 100 also contains a battery 108 that powers the various electrical components inside the nest. The cabin assembly 100 also houses a main control box assembly 109, which houses the nest's control system. The main control box assembly 109 is responsible for signal reception and processing, continuously receiving sensor signals, processing them, and sending control commands to actuators such as motors and cooling components. It flexibly controls the operation of each component based on the actual operating conditions of the nest, achieving automated nest operation and intelligent management of the drone. For example, it adjusts the cooling components based on temperature and controls the hatch and centering platform based on the drone's position.
