[0002] This disclosure claims priority to Chinese Patent Application No. 2024107759685, entitled "A Type of Unmanned Aerial Vehicle Nest," filed on June 17, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of unmanned aerial vehicle (UAV) technology, and more particularly to a UAV nest. Background Technology

[0004] When drones perform outdoor flight missions, they inevitably encounter situations where their batteries run out. Currently, to reduce the need for human intervention and labor, drone battery swapping is usually done through drone nests.

[0005] In existing technologies, after a drone lands, its landing position is not uniform, and the propeller angles of the drones are different. If the drone is not adjusted to the center of the drone nest and the propellers are left to scatter, the entire drone will occupy a large amount of storage space in the drone nest, resulting in wasted space and making the drone nest quite bulky.

[0006] Public content

[0007] The purpose of this disclosure is to provide a drone nest that allows adjustment of the drone's position and propeller orientation to ensure efficient space utilization.

[0008] To achieve this objective, the present disclosure adopts the following technical solution:

[0044] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the drawings, not the entire structure.

[0045] In the description of this disclosure, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0046] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0047] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0048] Referring to Figures 1 to 3, this embodiment provides a drone nest, which is applied to drone 10.

[0049] Optionally, the drone 10 includes four propellers 11 spaced around its body.

[0050] Optionally, the drone nest includes a deck 100, a centering device 200, and a propeller lever 300. The deck 100 is configured to hold the drone 10. The centering device 200 is located on the deck 100 and includes two first levers 210 arranged side-by-side along a first direction and two second levers 220 arranged side-by-side along a second direction. In the figure, direction a represents the first direction, and direction b represents the second direction. Both directions can be horizontal. For example, the first and second directions can be perpendicular to each other.

[0051] The two first levers 210 are movable relative to each other along a first direction and have a first initial position and a first centering position. When the first lever 210 moves from the first initial position to the first centering position, it can push the drone 10 to a preset position on the deck 100 along the first direction. The two second levers 220 are movable relative to each other along a second direction and have a second initial position and a second centering position. When the second lever 220 moves from the second initial position to the second centering position, it can push the drone 10 to a preset position on the deck 100 along the second direction.

[0052] Optionally, each of the first levers 210 has a propeller lever 300 rotatably mounted at both ends. The propeller lever 300 can rotate between a horizontal and a vertical position. In the vertical position, the propeller lever 300 can move the propeller blades 11 of the UAV 10 to a preset orientation as the first lever 210 moves. The propeller lever 300 and the propeller blade 11 are configured in a one-to-one correspondence, meaning the propeller lever 300 can move the propeller blades 11 in a corresponding manner. In the horizontal position, the propeller lever 300 can be approximately parallel to the deck 100; in the vertical position, the propeller lever 300 can be approximately perpendicular to the deck 100. The preset orientation angle can be a range value.

[0053] Initially, the first lever 210 is in the first initial position, the second lever 220 is in the second initial position, and the propeller lever 300 is in the horizontal position to create clearance and avoid interference with the incoming UAV 10. After the UAV 10 is placed on the deck 100, the propeller lever 300 is rotated to the vertical position. The first lever 210 moves from the first initial position to the first centering position to push the UAV 10 to a preset position on the deck 100 along the first direction. The second lever 220 moves from the second initial position to the second centering position to push the UAV 10 to a preset position on the deck 100 along the second direction, thereby achieving the centering adjustment of the UAV 10. In addition, during the movement of the first lever 210, the propeller lever 300 can push the propeller blades 11 and move the corresponding propeller blades 11 to a preset orientation, effectively improving the space utilization of the UAV nest and ensuring the structural compactness of the UAV nest.

[0054] In this embodiment, referring to Figures 1 to 4, the propeller lever 300 is connected to an elastic element 400. The elastic element 400 ensures that the propeller lever 300 always has a tendency to rotate from a horizontal position to a vertical position. The second lever 220 can abut against the propeller lever 300 in a second initial position, keeping the propeller lever 300 in a horizontal position. In this embodiment, initially, the second lever 220 is engaged with the propeller lever 300 in the second initial position, and the propeller lever 300 remains in a horizontal position. During the movement of the second lever 220 from the second initial position to the second centering position, the second lever 220 disengages from the propeller lever 300. Under the action of the elastic element 400, the propeller lever 300 rotates from a horizontal position to a vertical position, which is convenient and reliable. Furthermore, as the first lever 210 moves, the corresponding propeller blade 11 is turned to a preset orientation.

[0055] In one feasible implementation, the paddle lever 300 is provided with a positioning groove 310, and the second lever 220 can be placed in the positioning groove 310 and press the groove wall of the positioning groove 310 to make the paddle lever 300 rotate from the vertical position to the horizontal position. Through the design of the positioning groove 310, the force between the second lever 220 and the paddle lever 300 can be improved, making the second lever 220 more suitable for pushing the paddle lever 300 to rotate to the horizontal position.

[0056] For example, the positioning groove 310 may be U-shaped, and its opening is positioned along the second direction toward the center of the deck 100.

[0057] For example, the end of the positioning groove 310 is provided with a chamfered surface and / or an arc surface to facilitate the movement of the second lever 220 into the positioning groove 310, thereby reducing the fitting accuracy and avoiding interference. The width of the positioning groove 310 may be greater than the diameter of the second lever 220.

[0058] In one feasible implementation, the paddle lever 300 is arranged perpendicular to the second lever 220 to better suit the second lever 220 to push the paddle lever 300 to rotate, and to make the structure on the deck 100 more compact.

[0059] In one feasible implementation, the rotation axis of the propeller lever 300 is further away from the deck 100 along a third direction than the positioning slot 310. When the second lever 220 is in the second initial position, the second lever 220 is located on the side of the rotation axis of the propeller lever 300 away from the center of the deck 100 along a second direction. This can make the structure on the deck 100 more compact, further improve the space utilization of the UAV nest, and ensure the structural compactness of the UAV nest. In the figure, direction c is the third direction, which can be a vertical direction.

[0060] In one feasible implementation, the first lever 210 is connected to a support 211, the support 211 is provided with an elastic element 400, and the lever 300 is hinged to the support 211 for easy assembly.

[0061] It is worth mentioning that the propeller lever 300 can also be driven to rotate by a drive unit (not shown), which includes, but is not limited to, a servo motor.

[0062] In this embodiment, referring to Figures 1, 3, and 5, the centering device 200 further includes a first transmission assembly 230, a second transmission assembly 240, a first bevel gear 251, a second bevel gear 252, and a motor 260. Two first transmission assemblies 230 are provided, respectively located on both sides of the deck 100 along a second direction. Each first transmission assembly 230 includes two first lead screws 231 arranged along a first direction and coaxially aligned, and two first threaded sleeves 232 corresponding to each lead screw 231. The threads of the two lead screws 231 in the same group are connected at opposite ends, and the two first threaded sleeves 232 in the same group are correspondingly connected to the first lever 210. The two lead screws 231 and the two first threaded sleeves 232 in the same group belong to the same first transmission assembly 230. Two second transmission assemblies 240 are provided, respectively located on both sides of the deck 100 along a first direction. Each second transmission assembly 240 includes two first bevel gears 251, two bevel gears 252, and a motor 260. The system comprises two coaxial second lead screws 241 arranged in the same direction and two corresponding second threaded sleeves 242 connected to each other. The two second lead screws 241 in the same group have opposite thread directions and are connected at opposite ends. The two second threaded sleeves 242 in the same group are connected to the second lever 220. Both the two second lead screws 241 and the two second threaded sleeves 242 belong to the same second transmission assembly 240. The opposite ends of the first lead screws 231 in the same group are respectively provided with first bevel gears 251, and the opposite ends of the second lead screws 241 in the same group are respectively provided with second bevel gears 252. Adjacent first bevel gears 251 and second bevel gears 252 are meshed together. A motor 260 is connected to either the first lead screw 231 or the second lead screw 241. A support 211 is mounted on the first threaded sleeve 232. In this embodiment, taking the connection between motor 260 and the first transmission component 230 as an example, the two motors 260 start and stop simultaneously. When the motor 260 is working, due to the meshing transmission of the first bevel gear 251 and the second bevel gear 252, the first lead screw 231 and the second lead screw 241 rotate synchronously, thereby driving the first threaded sleeve 232 and the second threaded sleeve 242 to move synchronously. Since the threads of the first lead screw 231 and the second lead screw 241 of the same group have opposite directions, the two first levers 210 move closer to each other while the two second levers 220 move closer to each other; and the two first levers 210 move further away from each other while the two second levers 220 move further away from each other, realizing the automated control of the synchronous movement of the first levers 210 and the second levers 220, which is convenient and reliable.

[0063] Optionally, at least one motor 260 is provided. Exemplarily, two motors 260 are provided, and each motor 260 is connected to one of the two first transmission components 230 or to one of the two second transmission components 240. Optionally, the motors 260 and the first lead screw 231 can be driven by a synchronous belt to increase the buffering effect, effectively preventing damage to the centering device 200 caused by asynchronous start-stop between the two motors 260, and effectively preventing the first lever 210 from damaging the drone 10. Exemplarily, the opposite ends of the two first lead screws 231 can be connected to the same pulley.

[0064] For example, the ends of the two first lead screws 231 facing each other and the ends of the two second lead screws 241 facing each other in the same group can be connected by a coupling.

[0065] For example, the centering device 200 also includes two first guide components 271 corresponding one-to-one with the first transmission component 230, the first guide components 271 being configured to guide the movement of the opposing first threaded sleeves 232 along a first direction.

[0066] For example, the first guide assembly 271 includes a first slide rail (not shown) disposed on the deck 100 and a first slider (not shown) slidably connected to the first slide rail. The first screw sleeve 232 is connected to at least one first slider, which facilitates assembly and provides stable and reliable guidance.

[0067] For example, the centering device 200 also includes two second guide components 272 corresponding one-to-one with the second transmission component 240, the second guide components 272 being configured to guide the movement of the opposing second threaded sleeves 242 in a second direction.

[0068] For example, the second guide assembly 272 includes a second slide rail (not shown) disposed on the deck 100 and a second slider (not shown) slidably connected to the second slide rail. The second screw sleeve 242 is connected to at least one second slider, which facilitates assembly and provides stable and reliable guidance.

[0069] In one feasible implementation, the centering device 200 further includes a position sensor 261, which detects the position of the first lever 210 and / or the second lever 220. For example, the position sensor 261 can be a slotted photoelectric switch. Optionally, multiple slotted photoelectric switches are arranged side-by-side along a second direction and located on one side of one of the second lead screws 241. A sensing element (not shown) is provided on a second threaded sleeve 242 connected to the second lead screw 241. The slotted photoelectric switch can sense the sensing element placed in its sensing slot, thereby obtaining the position information of the second threaded sleeve 242, and thus determining the position information of the first lever 210 and the second lever 220.

[0070] In one feasible implementation, the centering device 200 further includes a limiting member 262, which limits the movable extreme positions of the first lever 210 and the second lever 220. Exemplarily, the limiting member 262 includes, but is not limited to, a bolt, a mechanical limit switch, and a photoelectric limit switch. Exemplarily, a set of limiting members 262 may be provided, corresponding to one of the second lead screws 241, i.e., a mechanical limit switch may be provided at the second initial position and the second centering position, and a bolt may be provided at the second centering position, which can limit the movement of the second threaded sleeve 242 to prevent excessive movement of the second threaded sleeve 242.

[0071] In this embodiment, referring to Figures 1, 3, 6 and 7, the drone nest also includes a battery swapping device 500 located on one side of the deck 100. The battery swapping device 500 is configured to install and remove the battery of the drone 10, effectively reducing the amount of manpower and labor required.

[0072] Optionally, a rack 600 is provided at the bottom of the deck 100, and the power swapping device 500 can be mounted on the rack 600. For example, the rack 600 can be formed by overlapping or welding pipe fittings. The pipe fittings can be rectangular tubes.

[0073] Optionally, the battery swapping device 500 may include a robotic arm 510 mounted on a frame 600 and a robotic hand 520 at the end of the robotic arm 510. The robotic hand 520 is used to remove the depleted battery from the drone 10 and insert a fully charged battery into the drone 10. The robotic hand 520 is prior art and will not be described in detail in this disclosure.

[0074] Optionally, the robotic arm 510 can be composed of multiple linear modules connected sequentially. These linear modules can be driven by lead screws; the specific structure is existing technology and will not be described in detail here.

[0075] It is worth mentioning that the drone nest can also directly charge the battery on the drone 10. For example, the drone nest also includes a charger (not shown) located on the deck 100, which charges the battery on the drone 10. The charger includes, but is not limited to, a wireless charger, a USB charger, and a solar charger.

[0076] In this embodiment, continuing to refer to Figures 1, 3, 6 and 7, the drone nest also includes a battery compartment 700 located at the bottom of the deck 100. The battery compartment 700 is configured to hold batteries, and the batteries in the battery compartment 700 are easily accessible by the battery swapping device 500 and can be swapped onto the drone 10.

[0077] For example, the drone nest can charge the battery inside the battery compartment 700.

[0078] For example, the battery compartment 700 can lock the battery in place using a cross-shaped latch (not shown) to secure the battery within the battery compartment 700 and prevent the battery from accidentally slipping out of the battery compartment 700.

[0079] For example, the battery compartment 700 has multiple compartments 710 for accommodating batteries, allowing the drone nest to sequentially replace the batteries of multiple drones 10. For instance, the battery compartment 700 may have 4-16 compartments 710 to ensure the compact structure of the drone nest. Preferably, the battery compartment 700 may have 8 compartments 710. Optionally, the compartments 710 of the battery compartment 700 may be arranged in pairs to improve the compactness of the battery compartment 700. Optionally, the compartments 710 of the battery compartment 700 may be arranged in one row or multiple rows; this disclosure does not limit the arrangement.

[0080] In this embodiment, referring to Figures 1, 3, 6 and 7, the robotic arm 510 includes a first linear module 511, a second linear module 512 and a third linear module 513 connected in sequence. The first linear module 511 is mounted on the frame 600 and configured to drive the robotic arm 520 to move along a second direction. The second linear module 512 is configured to drive the robotic arm 520 to move along a third direction. The third linear module 513 is configured to drive the robotic arm 520 to move along a first direction.

[0081] In one feasible implementation, the deck 100 is a split design, wherein the deck 100 includes a fixed plate 110 and a movable plate 120. The fixed plate 110 is fixed to the frame 600, and the movable plate 120 is covered on the robot arm 520 and can move with the robot arm 520 to further improve the space utilization of the UAV nest and ensure the structural compactness of the UAV nest.

[0082] For example, the process of removing the battery from the drone 10 is as follows: After the drone 10 completes its centering adjustment, the second linear module 512 can be controlled to move the robotic arm 520 along a third direction to correspond with the drone 10 along a second direction. Then, the third linear module 513 can be controlled to move the robotic arm 520 towards the drone 10 along a first direction. After the robotic arm 520 grabs the battery from the drone 10, the third linear module 513 and the second linear module 512 are reset in sequence. Finally, the first linear module 511 is controlled to move the battery along the second direction to correspond with the empty compartment 710. The third linear module 513 can then move the robotic arm 520 towards the drone 10 along the first direction. The robotic arm 520 places the battery into the compartment 710, and the first linear module 511 is reset.

[0083] For example, the process of installing the battery into the drone 10 is as follows: After the battery of the drone 10 is removed, the first linear module 511 can be controlled to move the robotic arm 520 along the second direction to the compartment 710 where the fully charged battery is located. The third linear module 513 drives the robotic arm 520 to move towards the drone 10 along the first direction. The robotic arm 520 grabs the battery, and the third linear module 513 and the first linear module 511 are reset in sequence. Then, the second linear module 512 is controlled to move the robotic arm 520 along the third direction to correspond to the drone 10 along the second direction. The third linear module 513 drives the robotic arm 520 to move towards the drone 10 along the first direction. The robotic arm 520 installs the battery onto the drone 10, and the third linear module 513 and the second linear module 512 are reset in sequence.

[0084] In this embodiment, referring to Figures 7 and 8, the UAV nest further includes a hatch 810 and a drive device 820. A receiving cavity can be formed between the hatch 810 and the deck 100. The drive device 820 is connected to the hatch 810 and configured to drive the hatch 810 to rotate or move, thereby opening and closing the hatch 810. The drive device 820 is mounted on the frame 600. In this embodiment, the hatch 810 allows the UAV 10 to be placed inside the receiving cavity, providing protection and making the UAV nest suitable for extreme operating environments.

Optionally, there are two second motors 291, each corresponding to one of the two second transmission assemblies 240, or there is one second motor 291 connected to both second transmission assemblies 240. In this embodiment, the second motor 291 drives the second lead screw 241 to rotate. Under the guidance of the second guide assembly 272, because the two second lead screws 241 rotate in opposite directions, the two second threaded sleeves 242 move away from or closer to each other, thereby realizing the reciprocating movement of the second lever 220 between the second initial position and the second centering position, ensuring safe and reliable transmission.

[0096] Optionally, the first motor 281 and the first lead screw 231, as well as the second motor 291 and the second lead screw 241, can be driven by synchronous belts.
