Description

Technical Field

[0001] The present invention relates to the technical field of UAV mounting systems, and particularly to a general UAV mounting system and its usage method. Background Art

[0002] In recent years, with the increasing number of high-rise buildings in cities and the increasingly complex urban structure, how to quickly deliver life-saving supplies or provisions during a fire has posed a great challenge to emergency rescue work. At the same time, with the improvement of people's living standards and the continuous improvement of the ecological environment, more people can go out of the city and engage in outdoor hiking and exploration, and the situation of people getting into trouble occurs frequently. The traditional rescue method is that rescue personnel conduct a dragnet search and a large-scale search for the people in trouble. However, there are relatively large risks in quickly locating the people in trouble and providing rescue, and the rescue ability is insufficient. Therefore, with the increasing maturity of UAVs, especially rotor UAVs, more and more market participants have launched special rescue UAVs. By setting a mounting system at the lower end of the UAV fuselage to facilitate the installation of search and positioning equipment and the delivery of supplies, the UAV can be used to replace manual search and rescue and transport rescue supplies, and can meet the requirements of rapid search, rescue supply delivery, and relay communication.

[0003] However, for existing special rescue UAVs, their mounting systems and related interfaces are all specific to their own brands and are not compatible with other UAVs. When the mounting system needs to be repaired or replaced after long-term use, there are disadvantages such as high price, complex installation and disassembly, and lack of universality, resulting in emergency rescue agencies being in a dilemma of "affordable to buy, unaffordable to use, and unaffordable to repair". Moreover, for heavy-load UAVs, these heavy-load rescue items need to be firmly connected to the bottom of the UAV to prevent the rescue items from shaking during flight. When the existing mounting system transports rescue items, the connection is not firm enough and the items cannot be quickly and stably hooked and disassembled, resulting in relatively low rescue transport efficiency. Summary of the Invention

[0004] To solve the technical problems existing in the prior art that the special mounting system is expensive, complex to install and disassemble, not universal, and the connection is not firm enough and the items cannot be quickly and stably hooked and disassembled, resulting in relatively low rescue transport efficiency, the present invention provides the following technical solutions.

[0005] A general UAV hanging rack system of the present invention includes a hanging rack main body mounted on the bottom of the UAV. The bottom of the UAV is connected with a UAV bottom plate with a number of first screw holes on both sides. The hanging rack main body includes two mounting trusses axially provided with a number of second screw holes, which are connected to the UAV bottom plate through a number of first wing bolts. On both sides of each mounting truss, there is a connecting member with legs connected to the lower part through a second wing bolt. Between the two mounting trusses, there is a bearing plate with a comprehensive control unit on the upper part and a battery pack on the lower part. The lower part of the bearing plate is connected with a number of clamp components for clamping materials. On one side of the clamp component, there is a shock-absorbing component fixedly connected to the bearing plate. The shock-absorbing component is connected with a three-axis gimbal with a monitoring component at the bottom.

[0006] As a further technical solution, on both sides of the bearing plate, there are fixed side plates fixedly connected to the mounting trusses and with a length less than that of the bearing plate. A number of second screw holes are evenly arranged in the axial direction of the mounting truss, and the connecting member moves away from or close to the fixed side plate in the axial direction of the mounting truss.

[0007] As a further technical solution, between each mounting truss and the UAV bottom plate, they are connected through at least two of the first wing bolts, and a limiting component for preventing the first wing bolts from loosening is connected between the two first wing bolts.

[0008] As a further technical solution, the limiting component includes two positioning blocks corresponding to the first wing bolts and provided with a number of limiting grooves. On one side of the two positioning blocks facing each other, there are universal ball hinges fixedly provided with adjusting screws connected, and on the side of the two adjusting screws facing each other, there is an adjusting nut sleeve connected.

[0009] As a further technical solution, the clamp component includes a manipulator fixedly connected to the bearing plate and provided with a driving member on the upper part. The driving member is connected with a torque feedback device, and the clamping end of the manipulator is provided with a force feedback device.

[0010] As a further technical solution, on both sides of the manipulator, there are two relatively arranged photoelectric monitors.

[0011] As a further technical solution, the shock-absorbing component includes a shock-absorbing member fixedly connected to the bearing plate, a linkage plate connected to the shock-absorbing member, and a connecting plate connected to the three-axis gimbal.

[0012] As a further technical solution, the shock-absorbing member includes a mounting plate fixedly connected to the bearing plate and provided with a fixed shaft. In the middle of the mounting plate, there is a shock-absorbing body sleeved and in contact with the linkage plate and the connecting plate.

[0013] As a further technical solution, the shock absorber is one of a rubber ball, a silica gel ball, an airbag or a damping metal.

[0014] The present invention also includes a method for using a general unmanned aerial vehicle mounting system, comprising the following steps:

[0015] S1: Wirelessly connect and match the integrated control unit with the unmanned aerial vehicle flight control system and the ground control terminal;

[0016] S2: After the matching is completed, remove the existing support legs at the bottom of the unmanned aerial vehicle, and open a plurality of first screw holes on the bottom plate of the unmanned aerial vehicle corresponding to the second screw holes on the mounting truss;

[0017] S3: According to the different weights of the monitoring equipment under the bearing plate and the materials to be mounted, find the center of gravity of the bearing plate, connect the mounting truss and the bottom plate of the unmanned aerial vehicle through the first wing bolts. After the first wing bolts are connected and fixed, sleeved the limiting components on the outer periphery of the two first wing bolts and tighten them so that the two first wing bolts will not loosen;

[0018] S4: According to the center of gravity of the bearing plate, make the connecting member drive the support legs to approach or move away from the fixed side plate, and adjust the positions of the two support legs under the bearing plate;

[0019] S5: Mount the materials to be mounted on the clamping member, detect the mounting state, and then perform the next flight monitoring and material delivery operations.

[0020] The beneficial effects of the present invention: The general unmanned aerial vehicle mounting system of the present invention uses an existing multi-rotor unmanned aerial vehicle as a vehicle, and designs a relatively independent mounting frame body. The mounting frame body can be quickly installed on the bottom plate of the unmanned aerial vehicle through the first wing bolts, and the limiting components prevent the first wing bolts from loosening, improving the connection stability. The connecting member can drive the support legs to move along the axial direction of the mounting truss and be installed through the second wing bolts, ensuring the center of gravity stability of the mounting truss relative to the unmanned aerial vehicle, preventing the rescue items from shaking during flight, and being compatible with the structures and electrical interfaces of existing mainstream multi-rotor unmanned aerial vehicles. It can be wirelessly connected to the existing flight control system and the ground control terminal, and can independently complete all functions of communication, measurement and control, and execution. The mounting frame body has stronger versatility. The bottom of the bearing plate is connected with a clamping member, which can quickly and stably hang and disassemble items, and the clamping member is provided with a force feedback device, a torque feedback device and a photoelectric monitor, providing support for the manipulator to adapt to different lifting requirements. The photoelectric sensing device is a group of photoelectric pairs, and by detecting the on-off signal, it is judged whether the lifted materials have been normally mounted or delivered, ensuring the rescue efficiency of the unmanned aerial vehicle.

Detailed implementation manners

[0033] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0034] In the description of the present invention, it should be understood that the terms "upper" and "lower" are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. In the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more.

[0035] As Figure 1 、 Figure 2 and Figure 3 shown, a general unmanned aerial vehicle (UAV) mounting rack system of the present invention includes a mounting rack main body 2 mounted on the bottom of the UAV 1. The UAV 1 uses an existing multi-rotor UAV. The mounting rack main body 2 can be detachably connected to most multi-rotor UAVs 1 on the market, ensuring the adaptability and universality of the mounting rack main body 2 and the UAV 1, and eliminating the need for a dedicated rescue UAV and a dedicated mounting rack.

[0036] In a preferred embodiment, the bottom of the UAV 1 is provided with a UAV bottom plate 101. A plurality of first screw holes 102 are provided on both sides of the UAV bottom plate 101. The first screw holes 102 can be existing ones on the UAV bottom plate 101, or the first screw holes 102 can be opened on site according to the following mounting truss 3. The opening of the first screw holes 102 is relatively simple, as long as the first screw holes 102 match the second screw holes 301 of the mounting truss 3.

[0037] As Figure 4 、 Figure 6 、 Figure 7 and Figure 8 shown, in a preferred embodiment, the mounting rack main body 2 includes two mounting trusses 3 connected to the UAV bottom plate 101. A plurality of second screw holes 301 are axially provided on the mounting trusses 3. Each mounting truss 3 has at least two second screw holes 301. Each second screw hole 301 matches the first screw hole 102. The first screw hole 102 and the second screw hole 301 are fixedly connected by a first wing bolt 10. Of course, a plurality of second screw holes 301 are axially provided on each mounting truss 3, and the second screw holes 301 cover the axis of the mounting truss 3 to facilitate the adjustment of the center of gravity of the mounting truss 3 relative to the UAV 1.

[0038] Specifically, the mounting truss 3 is made of an aluminum square tube with a size of 50mm * 50mm. Second screw holes 301 are designed on the surface of the mounting truss 3 at certain intervals, which facilitates tool - free disassembly and assembly using the first wing bolt 10 and can adjust the installation distance according to different models of the unmanned aerial vehicle 1. The aluminum alloy square tube is light in weight, and its relatively large cross - sectional area improves the torsional stiffness and strength of the mounting truss 3, providing good supporting ability for the bearing plate 6 to carry rescue supplies and monitoring equipment.

[0039] In a preferred embodiment, a bearing plate 6 is fixedly connected between the two mounting trusses 3. Supplies for rescue and monitoring equipment can be mounted below the bearing plate 6. Fixed side plates 601 that are fixedly connected to the mounting trusses 3 and have a length less than that of the bearing plate 6 are provided on both sides of the bearing plate 6. The fixed side plates 601 can be welded or bolt - connected to the mounting trusses 3. Connecting members 4 with legs 5 connected to the lower part are respectively connected to both sides of each mounting truss 3 through second wing bolts 11. The legs 5 are made of 30mm carbon fiber bent pipes, which have the advantages of light weight, large structural strength, and good rigidity. The connecting members 4 are provided with screw holes both above and below. Its lower part is bolt - connected and fixed to the legs 5, and the screw hole in its upper part matches the second screw hole 301 and is connected and fixed by the second wing bolt 11.

[0040] According to the different weights of the supplies and monitoring equipment mounted below the bearing plate 6, a plurality of second screw holes 301 are evenly arranged in the axial direction of the mounting truss 3. The connecting member 4 moves away from or close to the fixed side plate 601 in the axial direction of the mounting truss 3, and the second wing bolt 11 connects and fixes the connecting member 4 to the mounting truss 3. Thus, the connecting member 4 can drive the leg 5 to move along the axial direction of the mounting truss 3 and be installed by the second wing bolt 11, ensuring the center of gravity stability of the mounting truss 3 relative to the unmanned aerial vehicle 1. It can be seen that the fixed side plate 601 is in the middle position of the bearing plate 6 so as not to affect the axial adjustment of the connecting member 4 on the mounting truss 3.

[0041] In a preferred embodiment, each mounting truss 3 is connected to the bottom plate 101 of the unmanned aerial vehicle through at least two first wing bolts 10. The first wing bolts 10 pass through the first screw holes 102 and the second screw holes 301 to connect and fix the mounting truss 3 to the bottom plate 101 of the unmanned aerial vehicle. A limiting component 7 for preventing the first wing bolts 10 from loosening is connected between the two first wing bolts 10 at the upper part of each mounting truss 3.

[0042] The limiting member 7 includes two positioning blocks 701 corresponding to the first wing bolt 10. The positioning blocks 701 are provided with a plurality of limiting grooves 702. The shape of the limiting grooves 702 matches the shape of the first wing bolt 10. The limiting grooves 702 can be engaged with the upper part of the first wing bolt 10, and the first wing bolt 10 is clamped by the positioning blocks 701. Universal ball hinges 703 are fixedly provided on one side of the two positioning blocks 701 facing each other. The universal ball hinges 703 are connected with adjusting screws 704. The thread directions of the two adjusting screws 704 are opposite. One side of the two adjusting screws 704 facing each other is connected with an adjusting nut 705. The number of the limiting grooves 702 can be one or more. In this embodiment, the number of the limiting grooves 702 is three. In this way, no matter the positions of the two ears on the upper part of the first wing bolt 10 are, with the cooperation of the rotation of the universal ball hinge 703, the limiting grooves 702 can always be engaged with the first wing bolt 10.

[0043] During use, first tighten the first wing bolt 10 to connect and fix the hanging truss 3 to the drone bottom plate 101. Then, according to the distance between the two first wing bolts 10, turn the adjusting nut 705. The two adjusting screws 704 drive the two universal ball hinges 703 and the two positioning blocks 701 to move relatively closer or farther away from each other. When the two positioning blocks 701 are directly above the two first wing bolts 10, swing the two positioning blocks 701 to engage the limiting grooves 702 with the upper part of the first wing bolt 10. Then, turn the adjusting nut 705 to tighten the two first wing bolts 10 by the two adjusting screws 704, preventing the first wing bolt 10 from loosening, improving the connection stability, and preventing the rescue supplies from shaking during flight.

[0044] Such as Figure 4 and Figure 5As shown, in a preferred embodiment, the bearing plate 6 fixedly connected between the two mounting trusses 3 is used to mount various materials and monitoring devices. The upper part of the bearing plate 5 is provided with a comprehensive control unit 12 and the lower part is provided with a battery pack 15. Among them, the battery pack 15 adopts a combined bin design, with an aluminum shell on the outer surface, an internal cooling fan, and a heat-conducting insulating pad inside. On the one hand, it can effectively dissipate heat from the battery and avoid battery failures caused by overheating; on the other hand, it can also buffer and damp the battery during takeoff and landing, playing a good protective role. The comprehensive control unit 12 mainly realizes functions such as DC-DC conversion, communication with the flight control system of the unmanned aerial vehicle 1, communication with the ground control terminal, monitoring the clamp state, controlling the clamp action, and observing the ground image. Among them, the communication with the flight control system of the unmanned aerial vehicle 1 is carried out through the wireless communication of the data transmission frequency point of the unmanned aerial vehicle 1, avoiding the electrical connection between the two, simplifying the usage process, and improving the convenience of use. The comprehensive control unit 12 is also provided with a communication antenna. The communication antenna adopts a multi-frequency and multi-channel design, which can be compatible with 2.4Ghz, 5Ghz, and emergency dedicated frequency points, and establish continuous and reliable communication support between the ground control terminal, the unmanned aerial vehicle 1, and the hanger main body 2.

[0045] As Figure 5 and Figure 9 shown, in a preferred embodiment, several clamp components 8 for clamping materials are connected to the lower part of the bearing plate 6. The clamp component 8 includes a manipulator 802 with a driving member 801 provided on the upper part fixedly connected to the bearing plate 6. The driving member 801 adopts a low-speed high-torque motor and a micro-miniature high-efficiency reducer for driving the manipulator 802. A force feedback device 803 is provided at the clamping end of the manipulator 802, and a torque feedback device 804 is connected to the driving member 801. The torque feedback accurately measures the motor state of the driving member 801 through an encoder and real-time feeds it back to the driver, thereby optimizing the driving current, ensuring a motion accuracy of up to 0.001 degrees, and significantly improving the speed response, providing support for the clamp to adapt to different lifting requirements. Two photoelectric monitors 805 are provided on both sides of the manipulator 802. The photoelectric monitors 805 are a group of photoelectric opposed tubes distributed on both sides of the bearing plate 6. By detecting the on-off signal, it is determined whether the lifted item has been normally mounted or delivered, ensuring the rescue efficiency of the unmanned aerial vehicle.

[0046] As Figure 10 and Figure 11 shown, in a preferred embodiment, a shock-absorbing component 9 fixedly connected to the bearing plate 6 is provided on one side of the clamp component 8. The shock-absorbing component 9 is connected to a three-axis gimbal 13 with a monitoring component 14 provided at the bottom. The monitoring component 14 adopts an existing camera device or infrared monitoring device for monitoring and judging the rescue environment. The three-axis gimbal 13 also adopts existing technology and can cooperate with the monitoring component 14 to monitor the rescue environment in multiple directions.

[0047] In a preferred embodiment, the shock-absorbing member 9 includes a shock-absorbing piece 901 fixedly connected to the bearing plate 6, a linkage plate 902 connected to the shock-absorbing piece 901, and a connecting plate 903 connected to the three-axis gimbal 13. The three-axis gimbal 13 and the monitoring component 14 are fixedly installed at the lower part of the connecting plate 903. When the three-axis gimbal 13 vibrates, the vibration passes through the connecting plate 903 and the shock-absorbing piece 901, and the linkage plate 902 transmits the vibration to each shock-absorbing piece 901, further reducing the adverse effect of the vibration on the three-axis gimbal 13.

[0048] In a preferred embodiment, the shock-absorbing piece 901 includes a mounting plate 904 fixedly connected to the bearing plate 6. The mounting plate 904 is fixedly provided with a fixed shaft 905. A shock-absorbing body 906 that abuts against the linkage plate 902 and the connecting plate 903 is sleeved in the middle of the mounting plate 904. The shock-absorbing body 906 is one of a rubber ball, a silicone ball, an airbag or a damping metal. When the three-axis gimbal 13 vibrates, the vibration is transmitted to the shock-absorbing body 906 through the connecting plate 903. The attenuated vibration is then transmitted to the linkage plate 902 by the shock-absorbing body 906. After that, the linkage plate 902 transmits the vibration to each shock-absorbing body 906, further reducing the adverse effect of the vibration on the three-axis gimbal 13.

[0049] The present invention also includes a method for using a general unmanned aerial vehicle hanging rack system, which includes the following steps:

[0050] S1: Wirelessly connect and match the integrated control unit 12 with the flight control system of the unmanned aerial vehicle 1 and the ground control terminal;

[0051] S2: After the matching is completed, remove the existing support legs at the bottom of the unmanned aerial vehicle 1, and open a plurality of first screw holes 102 on the unmanned aerial vehicle bottom plate 101 corresponding to the second screw holes 301 on the hanging truss 3;

[0052] S3: According to the different weights of the monitoring equipment and the materials to be hung under the bearing plate 6, find the center of gravity of the bearing plate 6, and connect the hanging truss 3 to the unmanned aerial vehicle bottom plate 1 through the first wing bolts 10. After the first wing bolts 10 are connected and fixed, sleeved the limiting member 7 on the outer periphery of the two first wing bolts 10 and tighten and lock it so that the two first wing bolts 10 will not loosen;

[0053] S4: According to the center of gravity of the bearing plate 6, make the connecting member 4 drive the legs 5 to approach or move away from the direction of the fixed side plate 601, and adjust the positions of the two legs 5 under the bearing plate 6;

[0054] S5: Hang the materials to be hung on the clamp member 8, detect the hanging state, and then perform the next flight monitoring and material delivery operations.

[0055] The preferred specific embodiments and examples of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments and examples. Within the scope of knowledge possessed by those skilled in the art, various changes or equivalent substitutions can be made without departing from the concept of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application belong to the scope protected by the present invention.
