Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a hyperspectral imager mounting and operating device for UAVs. Background Technology

[0002] Hyperspectral imagers can simultaneously acquire spatial and spectral information of ground features and are widely used in remote sensing fields such as mineral exploration, vegetation monitoring, and environmental surveys. They are often combined with multi-rotor drones to achieve low-altitude, high-precision mapping. Currently, the industry commonly uses DJI M600 Pro drones equipped with Headwall full-band hyperspectral imagers for operations. However, this drone has limited payload capacity and insufficient battery life. The overall weight increases after mounting the imager, and the actual effective loiter time is only about 10 minutes, resulting in a very small coverage area per sortie. Furthermore, frequent takeoffs and landings to change batteries significantly reduce operational efficiency, making it completely unsuitable for large-area, long-endurance remote sensing missions in the field.

[0003] To overcome the endurance bottleneck, the operations team attempted to use the KOBIT Cloud Dragon II UAV as an alternative platform. This model boasts a higher power system, larger payload, and significantly extended endurance, theoretically capable of supporting long-duration field mapping operations. However, the Cloud Dragon II's fuselage mounting structure and mounting holes differ from the DJI M600 Pro. Its standard mounting components are not designed for the Headwall imager's dimensions and wiring harness, making direct installation incompatible. Temporary modifications or the use of non-dedicated adapters not only result in poor installation reliability and flight safety hazards but also negatively impact spectral imaging quality due to vibration transmission.

[0004] Therefore, a dedicated mounting structure is urgently needed to achieve a stable connection and electrical interconnection of the Headwall full-band hyperspectral imager on the Illumination Dragon II UAV. Summary of the Invention

[0052] The control component, through a linkage structure with gears, racks, and a first connecting rod as the main components, enables rapid operation of unlocking with a single hand press and self-locking upon release, simplifying the loading and unloading process. At the same time, each lock uses a double rack symmetrical drive to ensure that there is no skew or jamming during the locking process and that the force is balanced after locking, thereby enhancing the connection rigidity and vibration resistance reliability of the mount and the UAV connector, providing a stable and safe installation foundation for the hyperspectral imager during long-term flight mapping.

[0053] The use of locking components allows operators to keep all locks in the retracted state with just a single press of the lever. After the mounting head is inserted, it will automatically lock without any additional operation, further simplifying the loading process and avoiding the tediousness of working with both hands or repeated alignment. This effectively improves the efficiency and reliability of loading operations in complex field environments.

[0054] This invention extends the space beneath the drone by using a support frame to accommodate the installation of a hyperspectral imager, and utilizes adjustable components to flexibly adjust the support dimensions. This allows the invention to adjust different support spans and heights according to actual needs. At the same time, the triangular support structure formed by the mounting frame and the tilting fixed axis effectively enhances the drone's anti-tipping ability upon landing, ensuring safe take-off and landing in complex terrain. Therefore, the support frame structure improves the versatility and reliability of this invention in diverse operational scenarios. Attached Figure Description

Detailed Implementation

[0068] The technical solution will be further described below with reference to specific embodiments. It should be noted that the terms "up," "down," "left," and "right" used in this document refer only to the position of the structure shown in the corresponding drawings. The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and have no sequential or technical meaning. Unless otherwise specified, terms such as "connection" and "linkage" in this application include both direct and indirect connections (linkages).

[0069] Example: A hyperspectral imager mounting and operating device for a UAV, see reference. Figures 1-3The device includes: a drone 01, and a connector 02 fixedly mounted on the bottom of the drone 01. The connector 02 has a mounting groove 0201 at its bottom for carrying objects in a mounted manner. The device also includes: a mounting frame 03 detachably fixed to the connector 02; the mounting frame 03 consists of a mounting head 0301, an adapter module 0302, and a docking shaft 0303, wherein the mounting head 0301 is plugged into the mounting groove 0201 to facilitate easy assembly and disassembly of the mounting frame 03; the adapter module 0302 has a built-in wiring structure and is electrically connected to the power terminal of the drone 01; a hyperspectral imager 04 detachably fixed to the bottom of the mounting frame 03 with its lens facing downwards; and a gimbal 0401 fixedly mounted on the hyperspectral imager 04; the gimbal 0401 has a built-in wiring structure and is electrically connected to the hyperspectral imager 04, and the power terminal of the gimbal 0401 is electrically connected to the adapter module 0302, so that the hyperspectral imager 04 and the drone 01 can be connected to each other. The device 01 enables power transmission and bidirectional data signal transmission; the connector 0402, fixedly installed at the end of the pan-tilt unit 0401, is matched with the docking shaft 0303 to enable quick assembly and disassembly of the hyperspectral imager 04; the lock 05 is slidably installed in the mounting slot 0201, with the sliding direction of the lock 05 perpendicular to the direction in which the mounting head 0301 is inserted into the mounting slot 0201; there are two sets of locks 05, symmetrically arranged in the mounting slot 0201, four in each set, and evenly arranged along the insertion direction; the mounting head 0301 has a corresponding locking groove 06 for each lock 05; control components are located in the mounting slot 0201 and connected to the two sets of locks 05 respectively. Each set of control components drives the locks 05 to move, so that each lock 05 is engaged with the corresponding locking groove 06 to lock the relative displacement between the mounting head 0301 and the mounting slot 0201, thereby achieving docking and locking and ensuring the stability and reliability of the installation structure.

[0070] In use, first insert the mounting bracket 03 into the mounting slot 0201 via the mounting head 0301, and operate the control component to insert the lock 05 into the corresponding locking slot 06 to securely fix the mounting bracket 03. Then, install the hyperspectral imager 04, which is fixed with the gimbal 0401 and the connector 0402, onto the mounting bracket 03 through the snap-fit ​​engagement of the connector 0402 and the docking shaft 0303. Finally, connect the power terminals of the UAV 01 and the gimbal 0401 to the adapter module 0302 respectively, thus completing the electrical connection of the entire unit. The UAV 01 can then stably power the hyperspectral imager 04, and the data collected by the hyperspectral imager 04 can be stably transmitted back.

[0071] This device, through a mounting bracket 03 adapted to both the UAV 01 and the hyperspectral imager 04, enables a stable docking between the UAV 01 and the hyperspectral imager 04. This effectively suppresses the interference of flight vibration on imaging accuracy, significantly improves installation reliability and flight safety, and extends the effective operating time per flight. It addresses the shortcomings of traditional platforms, such as insufficient battery life and interface incompatibility, and meets the continuous operation requirements for large-area field remote sensing mapping.

[0072] See Figures 4-7 Each control assembly includes: a guide frame 0501 fixedly installed in the mounting slot 0201; two racks 0502 slidably installed on the guide frame 0501, the movement direction of the racks 0502 being perpendicular to the sliding direction of the locks 05; the two racks 0502 are symmetrically arranged with their teeth facing each other; a first connecting rod 0503 rotatably installed between the racks 0502 and each lock 05 to convert the reciprocating linear motion of the racks 0502 into the reciprocating linear motion of the locks 05; for each lock 05, each of the two racks 0502 is connected to a first connecting rod 0503, the two first connecting rods being symmetrically arranged along the axis of the lock 05 to convert the reciprocating linear motion of the racks 0502 into the reciprocating linear motion of the locks 05. The reciprocating linear motion ensures that the lock 05 is subjected to balanced force and moves smoothly; the mounting shaft 0504 is fixedly installed in the mounting groove 0201 corresponding to each lock 05; the gear 0505 mounted on the mounting shaft 0504 rotates, and each gear 0505 meshes with two racks 0502 simultaneously to achieve synchronous reverse movement of the two racks 0502; the first return torsion spring 0506 is sleeved on each mounting shaft 0504, and the first return torsion spring 0506 keeps the lock 05 in the locked position extending out of the mounting groove 0201 in its natural state; the lever 0507 is fixedly installed at the end of one of the racks 0502, and the lever 0507 extends out of the mounting groove 0201 for the operator to press and drive.

[0073] When the mounting head 0301 needs to be inserted, press the lever 0507, causing the corresponding rack 0502 to slide along the guide frame 0501. This, in turn, causes the gear 0505 to rotate and compress the first return torsion spring 0506. Simultaneously, the gear 0505 engages and drives the other rack 0502 to move in the opposite direction at an equal distance, causing the two racks 0502 to move away from each other. At this time, the lower ends of the two first connecting rods 0503 connected to both sides of the same lock 05 move away from each other, retracting the lock 05 downwards into the mounting slot 0201, thus making way for the insertion of the mounting head 0301. Once the mounting head 0301 and mounting groove 0201 are accurately aligned, and each lock 05 is aligned with its corresponding lock groove 06, release the lever 0507. The first reset torsion spring 0506 releases its elastic potential energy, driving the gear 0505 to rotate in the opposite direction. The two racks 0502 move towards each other to reset, and the lower ends of the two first connecting rods 0503 move closer to each other, thereby smoothly pushing the lock 05 upwards and accurately inserting it into the lock groove 06, thus achieving axial locking between the mounting head 0301 and the mounting groove 0201.

[0074] The control component, through a linkage structure with gear 0505, rack 0502, and first connecting rod 0503 as the main components, enables quick operation of unlocking with a single hand press and self-locking upon release, simplifying the loading and unloading process. At the same time, each lock 05 adopts a symmetrical drive with double racks 0502 to ensure that there is no skew or jamming during the lifting and lowering process of the lock 05, and that the force is balanced after locking, thereby enhancing the connection rigidity and vibration resistance reliability between the mounting frame 03 and the connecting seat 02 of the UAV 01, providing a stable and safe installation foundation for the hyperspectral imager 04 during long-term flight mapping.

[0075] See Figure 6 , Figure 8 and Figure 9 The device also includes a locking component disposed in the mounting slot 0201 corresponding to each control component. The locking component is used to cooperate with the control component to keep the lock 05 in the mounting slot 0201 during the insertion of the mounting head 0301, and automatically release the lock 05 after the mounting head 0301 and the mounting slot 0201 are fully engaged to complete the locking, thereby further improving the ease of use of the device.

[0076] Each locking assembly includes: a locking shaft 0701 rotatably mounted in the mounting groove 0201, the locking shaft 0701 consisting of a lower I-beam plate and an upper shaft rod, the outer surface of which has a spiral groove 0702; a locking hook 0703 rotatably mounted on the end of one of the racks 0502, used to engage with the I-beam plate to limit the position of the rack 0502; a second return torsion spring 0704 sleeved on the rotating shaft of the locking hook 0703, one end of which is fixed to the locking hook 0703 and the other end is fixed to the rack 0502, used to return the locking hook 0703; a guide rod 0705 fixedly mounted in the mounting groove 0201; a movable frame 0706 slidably mounted on the guide rod 0705; and a push pin 0707 fixedly mounted on the lower end of the movable frame 0706, the push pin 0707 slidably engaging with the locking shaft. The spiral groove 0702 on 0701 converts the axial displacement of the movable frame 0706 into the rotational movement of the locking shaft 0701; the return spring 0708, sleeved on the guide rod 0705, has one end fixed to the movable frame 0706 and the other end fixed to the guide rod 0705; the top plate 0709, rotatably mounted on the mounting groove 0201, is located at the mating surface between the mounting groove 0201 and the mounting head 0301; the second connecting rod 0710, rotatably connected between the top plate 0709 and the movable frame 0706, converts the rotational movement of the top plate 0709 into the sliding movement of the movable frame 0706; the third return torsion spring 0711, sleeved on the rotating shaft of the top plate 0709, has one end fixed to the top plate 0709 and the other end fixed to the mounting groove 0201.

[0077] In the initial state where the mounting slot 0201 is not connected to the mounting head 0301, the elastic force of the third reset torsion spring 0711 causes the top plate 0709 to tilt and protrude from the mating surface of the mounting slot 0201. At the same time, the reset spring 0708 is in a naturally extended state and keeps the axial position of the locking shaft 0701 fixed by the moving frame 0706 and the ejector pin 0707. When the operator moves all racks 0502 by pressing the lever 0507, the locking hook 0703 moves synchronously toward the locking shaft 0701 along with the racks 0502. When the pointed hook of the locking hook 0703 contacts the I-beam, it deflects against the elastic force of the second return torsion spring 0704. After the pointed hook passes the edge of the I-beam, the second return torsion spring 0704 drives the locking hook 0703 to rotate, so that the pointed hook engages and locks with the I-beam, fixing the position of the racks 0502 and keeping all locks 05 in the mounting slot 0201, so that the mounting head 0301 can be inserted without obstruction.

[0078] When the mounting bracket 03 is installed onto the connecting seat 02, the mounting head 0301 is gradually inserted along the mounting groove 0201. When the mating surfaces of the two are nearly fully aligned, the end of the mounting head 0301 moves to contact the top plate 0709. As the insertion continues, the mounting head 0301 presses the top plate 0709, causing it to rotate toward the inside of the mounting groove 0201. The third return torsion spring 0711 is compressed. At the same time, the top plate 0709 pushes the moving frame 0706 to slide downward along the guide rod 0705 through the second connecting rod 0710. The return spring 0708 is compressed, and the ejector pin 0707 at the lower end of the moving frame 0706 then slides along the spiral groove 0702, driving the locking shaft 0701 to rotate in the opposite direction, causing the I-beam plate to disengage from the pointed hook of the locking hook 0703. At this time, the first reset torsion spring 0506 releases its elastic potential energy, drives the rack 0502 to move in the reverse reset direction, and then pushes the lock 05 to extend upward out of the mounting groove 0201 and automatically insert into the corresponding lock groove 06, thus completing the locking of the mounting head 0301 and the mounting groove 0201.

[0079] The use of locking components allows operators to keep all locks 05 in the retracted state by pressing the lever 0507 once. After inserting the mounting head 0301, it will automatically lock without any additional operation, further simplifying the loading process and avoiding the tediousness of two-handed operation or repeated alignment, effectively improving the efficiency and reliability of loading operations in complex field environments.

[0080] See Figures 10-12 The device also includes: a support frame 08 fixedly installed on the lower part of the UAV 01, which is used to expand the space below the UAV 01 to accommodate the hyperspectral imager 04 when the UAV 01 is parked; and legs 10 symmetrically arranged at the bottom of the support frame 08, which are used to increase the span of the support frame 08 from the ground and achieve stable support.

[0081] See Figures 10-12The support frame 08 includes: a rectangular mounting frame 0801 fixedly installed at the bottom of the UAV 01, the mounting frame 0801 avoiding the connecting seat 02 and the mounting bracket 03 structure below the UAV 01; fixed shafts 0802 symmetrically fixedly installed on the left and right sides of the mounting frame 0801, the fixed shafts 0802 being inclined to form a triangular structure with the mounting frame 0801 to improve support stability; an extension shaft 0803 slidably installed along the axial direction at the lower part of the fixed shaft 0802, the support legs 10 being fixed to the end of the extension shaft 0803 and arranged on both sides of the hyperspectral imager 04; the entire support structure composed of the support frame 08 and the support legs 10 bypasses the hyperspectral imager 04 to avoid obstructing its lens; and screws 0901 rotatably installed in each extension shaft 0803, each screw 0901 being threadedly engaged with the corresponding fixed shaft 0802.

[0082] See Figures 11-12 The device also includes an adjustment component located in the support frame 08, which is used to control the size adjustment of the support frame 08 to simplify the operation steps and realize convenient adjustment of the size of the support frame 08.

[0083] See Figures 11-12 The adjustment assembly includes: a connecting frame 0902 fixedly installed at the middle of the front part of the mounting frame 0801; a first transmission rod 0903 rotatably installed inside the front part of the mounting frame 0801 and inside the connecting frame 0902; a worm gear 0904 fixedly installed on the shaft of the first transmission rod 0903, the worm gear 0904 being located inside the connecting frame 0902; a worm 0905 rotatably installed on the connecting frame 0902, the worm 0905 meshing with the worm gear 0904, its rod end being located outside the connecting frame 0902 and having a knob fixedly installed thereon; second transmission rods 0906 rotatably installed on the left and right sides of the connecting frame 0902; and first bevel gears 0907 respectively fixedly installed on the left and right shaft ends of the first transmission rod 0903 and the front shaft ends of the second transmission rods 0906 on both sides. The first bevel gear 0907 at the left shaft end of the first transmission rod 0903 meshes with the first bevel gear 0907 at the front shaft end of the second transmission rod 0906 on the left side, and the first bevel gear 0907 at the right shaft end of the first transmission rod 0903 meshes with the first bevel gear 0907 at the front shaft end of the second transmission rod 0906 on the right side; the second bevel gears 0908 are fixedly installed at the rear shaft end of the second transmission rod 0906 and the upper shaft ends of the screws 0901 on both sides, wherein the second bevel gear 0908 at the rear shaft end of the second transmission rod 0906 on the left side meshes with the second bevel gear 0908 at the upper shaft end of the screw 0901 on the left side, and the second bevel gear 0908 at the rear shaft end of the second transmission rod 0906 on the right side meshes with the second bevel gear 0908 at the upper shaft end of the screw 0901 on the right side.

[0084] The operator turns the knob to drive the worm gear 0905 to rotate, and the rotational driving force is transmitted to the first transmission rod 0903 through the worm wheel 0904 and worm gear 0905 transmission pair. The first transmission rod 0903 then changes the transmission direction through the first bevel gears 0907 at both ends, synchronously driving the second transmission rods 0906 on both sides to rotate. The second transmission rods 0906 on both sides further change the transmission direction again through the second bevel gears 0908 at their respective rear shaft ends, synchronously driving the screws 0901 on both sides to rotate. Since each screw 0901 is threadedly engaged with the corresponding fixed shaft 0802, and the extension shaft 0803 is axially slidingly engaged with the fixed shaft 0802, the rotation of the screw 0901 drives the extension shaft 0803 to move axially relative to the fixed shaft 0802, thereby realizing the synchronous extension and retraction adjustment of the length of the support arms on both sides, and completing the adjustment of the overall size of the support frame 08.

[0085] The adjustable components allow operators to simultaneously control the extension shafts 0803 on both sides via a single knob for telescopic adjustment, significantly improving operational convenience. Simultaneously, the self-locking characteristics of the worm gear 0904 and worm 0905 pair ensure that the support frame 08 remains dimensionally stable after adjustment, preventing accidental extension or retraction due to gravity or vibration. This guarantees the reliability and stability of the support structure during the UAV 01's landing, effectively preventing damage to the hyperspectral imager 04 due to impact.

[0086] This device extends the space below the UAV 01 via the support frame 08 to accommodate the installation of the hyperspectral imager 04, and utilizes adjustment components to flexibly adjust the support dimensions, allowing the invention to adjust different support spans and heights according to actual needs. At the same time, the triangular support structure formed by the mounting frame 0801 and the inclined fixed shaft 0802 can effectively enhance the anti-tipping ability of the UAV 01 when landing, ensuring safe take-off and landing in complex terrain in the field. Therefore, the support frame 08 structure can improve the versatility and reliability of the invention in diverse operating scenarios.

[0087] See Figure 1 and Figure 10 The device also includes: a bracket 1101 fixedly mounted on the top of the UAV 01; and a GPS module 11 fixedly mounted on the bracket 1101, the terminals of which are electrically connected to the hyperspectral imager 04. The GPS module 11, located on the unobstructed top of the UAV 01, can stably receive satellite signals, thereby providing accurate GPS coordinate information for the hyperspectral imager 04, facilitating subsequent spatial positioning and geographic correction of remote sensing data.
