Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) technology, and more particularly to a hoisted multi-target precision detection UAV. Background Technology

[0002] Multi-target precision detection drones are professional drone systems that integrate multi-sensor fusion technology and AI intelligent algorithms. They can simultaneously identify, locate, track, and analyze multiple targets in complex environments and provide high-precision data support as an aerial operation platform. The hoisting design provides core advantages such as all-around field of view, modular adaptability, high precision and stability, safety and convenience, making it the optimal technical solution for achieving multi-target precision detection. It is widely used in security, emergency response, industry, military and other fields, greatly improving detection efficiency and accuracy, and reducing operational risks and costs.

[0003] Currently, conventional multi-target reconnaissance UAVs mostly use integrated fixing or simple binding methods for their detection cabins and material pods, lacking dedicated mechanized positioning and locking structures. The process of disassembling and replacing pods is cumbersome and time-consuming, making it difficult to quickly switch between detection and material transport modes, and thus unable to adapt to complex and ever-changing on-site operational needs, resulting in low overall hoisting efficiency. Furthermore, traditional UAV hoisting structures have poor reliability, mostly relying on ordinary buckles and ropes for fixation. During UAV flight, airflow disturbances and fuselage vibrations can easily cause the pods to sway, shift, or even loosen, which not only causes… The shift in the field of view of cameras and detectors significantly reduces the accuracy of multi-target detection and terrain surveying, and can also disrupt the flight balance of drones, posing safety hazards such as pod falls and loss of flight control. Existing detection drones have relatively simple functional divisions, with most devices only equipped with image acquisition and environmental detection modules. The hoisting structure is only used to fix the detection equipment and does not have the capacity to carry materials. In scenarios such as emergency rescue, field disaster relief, and outdoor operations, it is necessary to use detection drones and material transport drones separately, resulting in large equipment investment, complex on-site scheduling processes, and insufficient emergency response and comprehensive operation capabilities.

[0004] To address the aforementioned issues, a hoisted multi-target precision detection UAV is proposed. Summary of the Invention

[0005] To overcome the above shortcomings, this invention provides a hoisted multi-target precision detection UAV, which aims to improve the problems of conventional multi-target precision detection UAVs, such as rudimentary pod installation, cumbersome disassembly and assembly, low operational efficiency, and fixed structures that are easily affected by airflow and vibration, resulting in shaking and loosening, which reduces detection accuracy and poses safety hazards. At the same time, the equipment has a single function and cannot take into account both detection and material transportation, resulting in poor scene adaptability.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a suspended multi-target precision detection UAV, comprising a body, with arms fixedly connected to each of the four corners of the body, a driver fixedly connected to the top of each arm, a propeller rotatably connected to the top of the outer side of the inner wall of each arm, landing gear fixedly connected to each of the four corners of the bottom of the body, a fixing component provided at the bottom of the body, a magnetic lock component provided at the bottom of the fixing component, a pod body provided inside the magnetic lock component, and support rods fixedly connected to the front and rear sides of the pod body; The fixing assembly includes a mounting plate, which is fixedly connected to the bottom of the machine body.

[0007] As a further description of the above technical solution: A camera is installed on the front side of the bottom of the inner wall of the machine body, a detector is installed on the rear side of the bottom of the inner wall of the machine body, signal devices are fixedly connected to the rear ends of the left and right sides of the top of the machine body, and an electronic controller is fixedly connected to the middle of the rear end of the top of the machine body.

[0008] As a further description of the above technical solution: The magnetic lock assembly includes two connecting plates, both of which are fixedly connected to the inner wall of the connecting frame. An electromagnetic lock is fixedly connected to the bottom outer side of each of the two connecting plates, and a connecting rod is snapped into the bottom of the electromagnetic lock. A connecting plate is fixedly connected to the bottom of each connecting plate, and a connecting plate is fixedly connected to the front and rear sides of each connecting plate.

[0009] As a further description of the above technical solution: The gear is rotatably mounted on the center of the bottom surface of the mounting plate via a rotating shaft. Both racks are meshed with the gear, and the gear is driven by the racks to generate rotational motion.

[0010] As a further description of the above technical solution: The two connecting frames move along the direction of the slide rail, and the slider moves in a straight line along the slide rail.

[0011] As a further description of the above technical solution: Both electric push rods are rotatably connected to the inner side of the connecting frame, and both limiting blocks are symmetrical about the center of the gear.

[0012] As a further description of the above technical solution: Both connecting rods are rotatably connected to the inner wall of connecting plate two.

[0013] As a further description of the above technical solution: The inner sides of connecting plate one, connecting plate two, and connecting plate three are all attached to the outer wall of the hoisting pod, and the support rods on the front and rear sides of the hoisting pod are arranged between the two sets of connecting plates three.

[0014] As a further description of the above technical solution: Assembly and locking process steps: S1: Two sets of electric push rods extend outward synchronously, the electric push rods push the connecting frame, the connecting frame drives the slider to move linearly outward along the slide rail, the connecting frame synchronously drives the rack to move, the rack drives the gear to rotate, and the two connecting frames separate symmetrically along the center of the gear. S2: Place the gondola between the two sets of connecting frames, so that the inner surfaces of connecting plate one, connecting plate two, and connecting plate three are in contact with the outer wall of the gondola; S3: The two sets of electric push rods retract inward synchronously, the electric push rods pull the connecting frame, the connecting frame drives the slider to move in a straight line along the slide rail, the rack moves in the opposite direction with the connecting frame and drives the gear to rotate in the opposite direction, the two connecting frames move in opposite directions synchronously and clamp the pod body; S4: Rotate the connecting rod on the inner wall of the connecting plate. The end of the connecting rod is embedded in the electromagnetic lock. The electromagnetic lock and the connecting rod are engaged, and the hoist body is locked and fixed.

[0015] Disassembly and separation process steps: S1: Release the jamming between the electromagnetic lock and the connecting rod, rotate the connecting rod, and the end of the connecting rod will rotate out from inside the electromagnetic lock; S2: Two sets of electric push rods extend outwards synchronously, the electric push rods push the connecting frame, the connecting frame drives the slider to move outwards in a straight line along the slide rail, the rack drives the gear to rotate, the two connecting frames separate symmetrically along the center of the gear, and release the clamping of the pod body; S3: Remove the pod from the space enclosed by connecting plate one, connecting plate two, and connecting plate three, and the pod will be disassembled and separated.

[0016] The present invention has the following beneficial effects: 1. In this invention, the UAV is equipped with a dedicated fixing component and a magnetic lock component. It relies on slide rails, sliders, gear racks and electric push rods to achieve synchronous clamping and positioning, and then uses an electromagnetic lock to complete the locking and fixing. The entire process can be completed without the need for additional tools to install and disassemble the pod. It can quickly replace the detection pod or the material pod, realize the rapid switching between detection operation and material delivery modes, effectively shorten the mission preparation time, significantly improve the overall hoisting operation efficiency of the UAV, and greatly improve the efficiency of operation by quickly assembling and disassembling.

[0017] 2. In this invention, the gear and rack transmission structure enables the clamping mechanisms on both sides to operate synchronously, achieving uniform force positioning of the pod. The electromagnetic lock, combined with multiple connecting plates, wraps around and limits the pod from multiple directions, forming a double locking structure. During flight, it can effectively counteract the effects of airflow and fuselage vibration, avoiding pod swaying and displacement. On the one hand, it stabilizes the UAV's flight attitude and avoids the risk of falling objects; on the other hand, it ensures that the cameras and detectors on the bottom of the fuselage maintain a stable working angle, making terrain, environmental, and multi-target detection data accurate and reliable, and ensuring secure locking, thus guaranteeing detection accuracy and flight safety.

[0018] 3. In this invention, the drone integrates a complete set of detection components such as cameras, detectors, signalers, and electronic controllers, and can independently complete terrain scanning, environmental monitoring, and multi-target identification and detection. The bottom-mounted pod can also carry conventional supplies, medical supplies, and other materials, combining precise detection with material transportation and emergency supply functions into one. It eliminates the need for multiple drones with different functions to work together, reducing equipment investment and scheduling costs. It can be widely used in various scenarios such as emergency rescue, field inspection, and disaster relief, with stronger comprehensive practicality, multiple uses, and enhanced scenario adaptability.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Reference Figure 1-9 An embodiment of the present invention provides a suspended multi-target precision detection UAV, comprising a body 1, with arms 2 fixedly connected to each of the four corners of the body 1, a driver 3 fixedly connected to the top of the arms 2, a propeller 4 rotatably connected to the top of the outer side of the inner wall of the arms 2, landing gear 5 fixedly connected to each of the four corners of the bottom of the body 1, a fixing component 8 provided at the bottom of the body 1, a magnetic lock component 9 provided at the bottom of the fixing component 8, a pod body 6 provided inside the magnetic lock component 9, and support rods 7 fixedly connected to the front and rear sides of the pod body 6.

[0023] In this embodiment, the body 1 is the core load-bearing base of the whole machine. The top of the four fixed arms 2 of the body 1 is equipped with a driver 3. The propeller 4 is rotated on the top of the outer side of the arm 2. The driver 3 drives the propeller 4 to rotate, providing flight power for the UAV. The four corners of the bottom of the body 1 are equipped with landing gear 5 to realize landing and parking support. The bottom of the body 1 is sequentially equipped with a fixing component 8 and a magnetic lock component 9. The pod body 6 is suspended inside the magnetic lock component 9. The front and rear sides of the pod body 6 are fixed with support rods 7. This layout integrates aerial detection and material carrying functions, realizes multiple uses of one machine, reduces the equipment investment at the work site, and can be adapted to various operation scenarios such as emergency rescue, field inspection, and environmental monitoring.

[0024] The fixing component 8 includes a mounting plate 801, which is fixedly connected to the bottom of the body 1. A mounting bracket 802 is fixedly connected to the bottom of the mounting plate 801. Slide rails 803 are fixedly connected to the front and rear sides of the bottom of the mounting bracket 802.

A rack 808 is symmetrically arranged on the top of the two connecting brackets 806 along the center of the gear 807. A limit block 809 is slidably connected through the outer wall of the rack 808.

[0025] In this embodiment, the fixing component 8 is fixed to the bottom of the body 1 by the mounting plate 801. The mounting bracket 802 is connected to the bottom of the mounting plate 801. The mounting bracket 802 has slide rails 803 arranged on the front and rear sides of the bottom of the bottom. Multiple sliders 804 are assembled on the outer wall of the slide rails 803. Two connecting brackets 806 are connected to the bottom of the sliders 804. A gear 807 is rotatably installed at the bottom center of the mounting plate 801. Electric push rods 805 are symmetrically arranged on the inner side of the connecting brackets 806. A rack 808 is symmetrically arranged on the top. The rack 808 passes through the limiting block 809. The entire set of gears 807, rack 808 and electric push rods 805 form a linkage transmission structure. The actions are synchronized and unified, which can quickly complete the clamping and release of the hoisting body 6, simplify the disassembly and assembly process, and improve the overall efficiency of hoisting operations.

[0026] A camera 13 is installed on the front side of the bottom of the inner wall of the body 1, a detector 12 is installed on the rear side of the bottom of the inner wall of the body 1, a signal device 10 is fixedly connected to the rear ends of the left and right sides of the top of the body 1, and an electronic controller 11 is fixedly connected to the middle of the rear end of the top of the body 1.

[0027] In this embodiment, a camera 13 is installed on the front side of the bottom of the inner wall of the body 1, and a detector 12 is installed on the rear side. The two types of detection components work together to complete image acquisition, environmental parameter detection and multi-target recognition. Signal devices 10 are fixed on the left and right sides of the top rear end of the body 1, and an electronic controller 11 is fixed in the middle. The electronic controller 11 coordinates the overall action logic of the machine, and the signal devices 10 realize remote command and detection data transmission. The entire set of detection and electronic control components operates stably, ensuring the accuracy of terrain and environmental detection data and meeting the needs of precise detection in complex scenarios.

[0028] The magnetic lock assembly 9 includes two connecting plates 901, both of which are fixedly connected to the inner wall of the connecting frame 806. An electromagnetic lock 904 is fixedly connected to the bottom outer side of the two connecting plates 901. A connecting rod 905 is snapped into the bottom of the electromagnetic lock 904. A connecting plate 902 is fixedly connected to the bottom of each connecting plate 901. A connecting plate 903 is fixedly connected to both the front and rear sides of the connecting plate 902.

[0029] In this embodiment, the connecting plate 901 of the magnetic lock assembly 9 is fixed to the inner wall of the connecting frame 806. An electromagnetic lock 904 is installed on the bottom outer side of the connecting plate 901. The bottom of the electromagnetic lock 904 is engaged with the connecting rod 905. The bottom of the connecting plate 901 is fixed with the connecting plate 902. The front and rear sides of the connecting plate 902 are fixed with the connecting plate 903. The connecting plates are combined to form a ring-shaped limiting structure. Together with the electromagnetic lock, they form a double locking system to resist the airflow and fuselage vibration, prevent the gondola 6 from loosening, and improve the flight safety factor.

[0030] Gear 807 is rotatably mounted on the center of the bottom surface of mounting plate 801 via a rotating shaft. Both racks 808 are meshed with gear 807, and gear 807 is driven by racks 808 to generate rotational motion.

[0031] In this embodiment, the gear 807 is rotatably mounted on the center of the bottom surface of the mounting plate 801 via a rotating shaft. Both racks 808 are meshed with the gear 807. When the racks 808 produce linear displacement, they can drive the gear 807 to rotate in the forward or reverse direction. Relying on the transmission characteristics of the gear and rack, the racks 808 on both sides and the connecting frame 806 keep moving synchronously. The mechanisms on both sides open and close synchronously, so as to achieve uniform force clamping on the pod body 6, avoid the offset problem caused by unilateral force, and ensure the continuous stability of the clamping state.

[0032] The two connecting brackets 806 move along the direction of the slide rail 803, and the slider 804 moves in a straight line along the slide rail 803.

[0033] In this embodiment, multiple sliders 804 are movably assembled on the outer wall of the slide rail 803. The connecting frame 806 follows the sliders 804 and moves linearly along the slide rail 803. The slide rail 803 and the sliders 804 form a low-resistance linear motion pair. The operation is smooth and without jamming. It can accurately cooperate with the electric push rod 805 to complete the opening and closing of the connecting frame 806, ensuring smooth and continuous disassembly and assembly of the pod body 6, effectively shortening the preparation time for operation, and further improving the efficiency of UAV hoisting operation.

[0034] Both electric push rods 805 are rotatably connected to the inside of the connecting frame 806, and both limit blocks 809 are symmetrical about the center of the gear 807.

[0035] In this embodiment, the electric push rod 805 is rotatably connected to the inner side of the connecting frame 806, which can adapt to the angle change when the connecting frame 806 is displaced. The two limit blocks 809 are arranged symmetrically with the center of the gear 807, which rigidly constrains the movement stroke of the rack 808, preventing the rack 808 from overtravel and causing structural damage. The symmetrical layout makes the transmission mechanism on both sides bear force evenly, and the whole machine still maintains synchronous operation during long-term operation, improving structural durability and operational reliability.

[0036] Both connecting rods 905 are rotatably connected to the inner wall of connecting plate 902.

[0037] In this embodiment, both connecting rods 905 are rotatably mounted on the inner wall of the connecting plate 902. The connecting rods 905 can rotate freely to complete the engagement and disengagement switching with the electromagnetic lock 904. The rotating connection structure is easy to operate, and the operator can switch the locking state without the need for external tools such as wrenches or ropes. Combined with the overall clamping structure, the hoist body 6 can be quickly disassembled, adapting to the diverse on-site operation switching needs.

[0038] The inner sides of connecting plate 1 (901), connecting plate 2 (902), and connecting plate 3 (903) are all attached to the outer wall of the hoisting body 6, and the support rods 7 on the front and rear sides of the hoisting body 6 are arranged between the two sets of connecting plates 3 (903).

[0039] In this embodiment, the inner surfaces of connecting plate 1 901, connecting plate 2 902, and connecting plate 3 903 are completely attached to the outer wall of the gondola body 6, forming a multi-faceted wrapping and limiting structure. The support rods 7 on the front and rear sides of the gondola body 6 are arranged between the two sets of connecting plates 3 903 to achieve auxiliary positioning. The multi-directional limiting structure greatly reduces the shaking caused by flight vibration, allowing the camera 13 and detector 12 to always maintain a stable viewing angle and ensuring the data accuracy of multi-target precise detection.

[0040] The assembly and locking process and the disassembly and separation process of the hoist body are performed sequentially as follows: Assembly and locking process steps: Two sets of electric push rods 805 extend outwards simultaneously, the electric push rods 805 push the connecting frame 806, the connecting frame 806 drives the slider 804 to move linearly outwards along the slide rail 803, the connecting frame 806 simultaneously drives the rack 808 to move, the rack 808 drives the gear 807 to rotate, and the two connecting frames 806 separate symmetrically along the center of the gear; the hoist body 6 is placed between the two sets of connecting frames 806, so that connecting plate one 901, connecting plate two 902, and connecting plate three 903 are connected. The inner surface is in contact with the outer wall of the hoisting body 6; two sets of electric push rods 805 retract inward synchronously, the electric push rods 805 pull the connecting frame 806, the connecting frame 806 drives the slider 804 to move linearly inward along the slide rail 803, the rack 808 moves in the opposite direction with the connecting frame 806 and drives the gear 807 to rotate in the opposite direction, the two connecting frames 806 move in opposite directions synchronously and clamp the hoisting body 6; the connecting rod 905 on the inner wall of the rotating connecting plate 2 902 is inserted into the electromagnetic lock 904, the electromagnetic lock 904 and the connecting rod 905 are engaged, and the hoisting body 6 is locked and fixed.

[0041] Disassembly and separation process steps: Release the jamming state between the electromagnetic lock 904 and the connecting rod 905, rotate the connecting rod 905, and the end of the connecting rod 905 rotates out from inside the electromagnetic lock 904; the two sets of electric push rods 805 extend outwards simultaneously, and the electric push rods 805 push the connecting frame 806. The connecting frame 806 drives the slider 804 to move linearly outwards along the slide rail 803. The rack 808 drives the gear 807 to rotate, and the two connecting frames 806 separate symmetrically along the center of the gear 807, releasing the clamp on the hoisting body 6; move the hoisting body 6 out of the space enclosed by the first connecting plate 901, the second connecting plate 902, and the third connecting plate 903, and the disassembly and separation of the hoisting body 6 is completed.

[0042] In this embodiment, the entire process of standardized assembly, locking, disassembly, and separation of the pod body 6 is achieved through the linkage of airborne components such as electric push rod 805, gear 807, and electromagnetic lock 904. The process steps are coherent and the action logic is clear. No external auxiliary tools are required throughout the process. It can quickly switch between two modes: detection operation and material delivery, which greatly improves the comprehensive operation capability of UAVs in complex scenarios such as disaster relief and field operations.

[0043] Working Principle: During routine flight and reconnaissance operations, the UAV body 1 serves as the main load-bearing structure. The actuator 3 at the top of the arm 2 drives the propeller 4 to rotate, providing lift and flight power for the entire aircraft. The landing gear 5 at the bottom of the body 1 provides support during landing. Inside the body 1, the camera 13 and detector 12 simultaneously collect images, environmental and target data. The electronic controller 11 coordinates the operation of all electrical components, and the signal transmitter 10 transmits the detection data and flight commands back to the ground terminal in real time, completing basic tasks such as multi-target identification, terrain surveying, and environmental monitoring. The fixing component 8 and magnetic lock component 9 remain in a retracted and locked state, and the pod 6 is firmly fixed to the bottom of the body. Connecting plates 901, 902, and 903 fully conform to the outer wall of the pod 6, which can offset flight vibration and airflow interference, prevent the pod 6 from swaying and shifting, and stabilize the detection perspective, thereby ensuring detection accuracy and flight safety.

[0044] When assembling the gondola body 6, the assembly and locking process is initiated: First, two sets of electric push rods 805 extend outwards simultaneously, pushing the connecting frame 806. The connecting frame 806 drives the slider 804 to move outwards along the slide rail 803. The rack 808 follows the displacement and drives the gear 807 to rotate, causing the two connecting frames 806 to separate symmetrically. Second, the gondola body 6 is placed between the two sets of connecting frames 806, so that the inner sides of each connecting plate are in contact with the outer wall of the gondola body 6. The support rod 7 is inserted between the connecting plates 903 to complete the initial positioning. Third, the electric push rods 805 retract inwards simultaneously, pulling the connecting frames 806 closer together to clamp the gondola body 6. The gear 807 rotates in the opposite direction to make the movements on both sides completely synchronized, achieving uniform force clamping. Fourth, the connecting rod 905 on the inner wall of the connecting plate 902 is rotated, causing the connecting rod 905 to engage inside the electromagnetic lock 904, completing the electromagnetic locking. The entire system features a dual structure of mechanical transmission and electromagnetic locking, providing high locking strength and capable of handling complex flight conditions.

[0045] When it is necessary to disassemble the pod body 6, the disassembly and separation procedure is performed: First, rotate the connecting rod 905 to release its engagement with the electromagnetic lock 904; then, the electric push rod 805 extends outward again, driving the connecting frame 806 to separate to both sides, releasing the clamp on the pod body 6; finally, the pod body 6 can be directly removed from the area enclosed by the connecting plate. The entire disassembly and assembly process is completed autonomously by the airborne structure, without the need for additional tools, and the disassembly and assembly speed is fast, allowing for quick switching between detection and material transportation operation modes.

[0046] The pod 6 can be loaded with supplies, medical supplies and other materials. While the drone completes precise surveying, it can simultaneously carry out emergency resupply and material delivery operations. There is no need to equip multiple single-function drones, which reduces equipment scheduling costs and significantly improves scene adaptability. All structures of the whole machine cooperate with each other, the transmission logic is coherent and the locking is safe and reliable, which comprehensively solves the problems of cumbersome disassembly and assembly, unstable fixation and single function of traditional drones.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
