[0029] In this document, "first", "second", etc. are only used for distinguishing from each other, rather than indicating importance, order, and the prerequisite for mutual existence, etc.

[0030] In this document, "equal", "same", etc. are not strict mathematical and / or geometric limitations, and also include errors that can be understood by those skilled in the art and are allowed in manufacturing or using, etc.

[0031] The present disclosure provides an unmanned aerial vehicle suspension system, including: an unmanned aerial vehicle, a hard connection device, and a soft connection device.

[0032] The drone can select the corresponding drone model that can meet the takeoff conditions of the mounted device according to the actual situation. In an embodiment of the present disclosure, the drone selects the DJI T40 model drone and installs a suspension system on its fuselage.

[0033] The rigid connection device includes: a vertical part and a mounting rod 5. Among them, the vertical part is fixedly connected to the bottom crossbar 1 of the drone, and the vertical part is configured to extend vertically from the bottom crossbar 1 of the drone to the mounting rod 5; the mounting rod 5 is perpendicular to the vertical part and fixedly connected to the vertical part, and the mounting rod 5 is configured to hang the device to be mounted.

[0034] Specifically, the rigid connection device as a whole presents an inverted T-shaped structure. Among them, the vertical part is fixedly connected to the bottom crossbar 1 of the drone, and the demagnetized screws are used for the fixed connection. The purpose is to solve the requirement of the non-magnetic environment for the normal operation of the detection device when the device to be mounted is a detection device. The vertical part extends vertically from the bottom crossbar 1 of the drone to the mounting rod 5. The purpose is to increase the distance between the drone fuselage and the device to be mounted, thereby reducing the center of gravity of the entire drone suspension system and the device to be mounted. Reducing the center of gravity can make the system more stable as a whole. Both the mounting rod 5 and the vertical part are rigid rods. The mounting rod 5 is perpendicular to the vertical part and is used to hang the device to be mounted.

[0035] The flexible connection device is fixedly connected to the bottom crossbar 1 of the drone and is configured to extend along the vertical part of the rigid connection device to the mounting rod 5. The flexible connection device is configured to connect the device to be mounted.

[0036] Specifically, the flexible connection device is installed inside the rigid connection device, one end is fixedly connected to the bottom crossbar 1 of the drone, and the other end extends along the vertical part of the rigid connection device to the mounting rod 5 and is connected to the device to be mounted. When the rigid connection device is damaged during the operation of the drone, in order to prevent the device to be mounted on the rigid connection device from falling from the air and causing danger, a flexible connection device is additionally provided. When the rigid connection device is damaged, the flexible connection device undertakes the function of mounting the device. However, since the length of the flexible connection device is set to be slightly longer than that of the rigid connection device, when the rigid connection device is intact, the flexible connection device only exists as an insurance measure and will not function.

[0037] In an embodiment of the present disclosure, the vertical part of the rigid connection device includes a first connecting rod 2. The first connecting rod 2 is configured to be perpendicular to the bottom crossbar 1 of the drone and is fixedly connected to the bottom crossbar 1 of the drone.

[0038] Specifically, the vertical part of the hard connection device consists of multiple connecting rods. After the UAV suspension system completes the hanging task, the UAV can also be used to perform other tasks. At this time, it is necessary to disassemble the hanging device from the UAV body. For convenient storage, the vertical part is composed of multiple rigid connecting rods. Among them, the first connecting rod 2 is perpendicular to the bottom crossbar 1 of the UAV and is fixedly connected to the bottom crossbar 1 of the UAV. The purpose is to extend the distance between the UAV body and the device to be hung along the vertical direction, thereby reducing the center of gravity of the overall device and increasing the stability of the overall device.

[0039] In an embodiment of the present disclosure, the vertical part of the hard connection device includes a second connecting rod 3, and the second connecting rod 3 is configured to extend along the extending direction of the first connecting rod 2 and is fixedly connected to the first connecting rod 2 through a connecting member 6.

[0040] Specifically, the second connecting rod 3 of the vertical part of the hard connection device has the same length as the first connecting rod 2. The second connecting rod 3 extends along the extending direction of the first connecting rod 2, that is, the vertical direction, and is connected to the first connecting rod 2 through a connecting member 6. The purpose is to extend the distance between the UAV body and the device to be hung along the vertical direction, thereby reducing the center of gravity of the overall device and increasing the stability of the overall device.

[0041] In an embodiment of the present disclosure, the vertical part of the hard connection device includes a third connecting rod 4, and the third connecting rod 4 is configured to extend along the extending direction of the second connecting rod 3. One end is fixedly connected to the second connecting rod 3 through a connecting member 6, and the other end is perpendicular to the hanging rod 5 and is fixedly connected to the hanging rod 5 through a connecting member 6.

[0042] Specifically, the third connecting rod 4 of the vertical part of the hard connection device has the same length as the first connecting rod 2. In this embodiment, the vertical part is composed of three connecting rods of the same length. One end of the third connecting rod 4 is fixedly connected to the second connecting rod 3, and the other end is fixedly connected to the hanging rod 5 through a connecting member 6. The hanging rod 5 is perpendicular to the third connecting rod 4, that is to say, the hanging rod 5 is horizontally arranged. The horizontal arrangement is more convenient for the device to be hung to be fixedly connected to the hanging rod 5. Among them, the length of the hanging rod 5 can be flexibly selected according to the hanging requirements of the device to be hung, and the length of the vertical part can also be adjusted according to actual working needs.

[0043] In an embodiment of the present disclosure, the connecting member 6 is arranged between the first connecting rod 2 and the second connecting rod 3, and between the second connecting rod 3 and the third connecting rod 4, and is configured such that the first connecting rod 2 and the second connecting rod 3, and the second connecting rod 3 and the third connecting rod 4 are detachably connected through the connecting member 6.

[0044] Specifically, the first connecting rod 2 and the second connecting rod 3 are detachably connected by a connecting member 6. The demagnetizing screw is used for the detachable connection, aiming to solve the requirement of non-magnetism for the normal operation of the detection device when the device to be mounted is a detection device. When using the connecting member 6 for connection, the first connecting rod 2 and the second connecting rod 3 are respectively fixed at both ends of the connecting member 6 by the demagnetizing screw. The second connecting rod 3 and the third connecting rod 4 are detachably connected by the connecting member 6. When using the connecting member 6 for connection, the second connecting rod 3 and the third connecting rod 4 are respectively fixed at both ends of the connecting member 6 by the demagnetizing screw. During the disassembly process, only the demagnetizing screw needs to be removed to disassemble the vertical part.

[0045] In an embodiment of the present disclosure, the first connecting rod 2, the second connecting rod 3, the third connecting rod 4, and the mounting rod 5 are all configured as hollow rods.

[0046] Specifically, the first connecting rod 2, the second connecting rod 3, the third connecting rod 4, and the mounting rod 5 are all configured as hollow rods, which can greatly reduce the self-weight of the UAV suspension system. When mounting equipment, it can reduce the load on the UAV body, making the selection of equipment that the UAV can mount more abundant and the tasks that can be executed more diverse.

[0047] In an embodiment of the present disclosure, the hard connection device is constructed to be made of carbon fiber or aviation aluminum.

[0048] Specifically, in order to reduce the self-weight of the UAV suspension system, the first connecting rod 2, the second connecting rod 3, the third connecting rod 4, and the mounting rod 5 in the hard connection device of the UAV suspension system are all made of carbon fiber or aviation aluminum. Aviation-grade aluminum is more than 3 times lighter than steel and more than 1.6 times lighter than titanium alloy under the same volume. Therefore, using connecting rods and mounting rods 5 made of aviation aluminum or carbon fiber materials can effectively reduce the self-weight of the UAV suspension system, thereby reducing the load on the UAV, making the selection of equipment that the UAV can mount more abundant and the tasks that can be executed more diverse.

[0049] In an embodiment of the present disclosure, the soft connection device is a rope, and the rope is constructed to extend downward from the bottom crossbar 1 of the UAV to connect with the device to be mounted.

[0050] Specifically, the flexible connection device in the UAV suspension system is a rope. One end of the flexible connection device is fixedly connected to the bottom crossbar 1 of the UAV, and the other end extends along the vertical part of the rigid connection device to the mounting rod 5 and is connected to the device to be suspended. When the rigid connection device is damaged during the operation of the UAV, in order to prevent the device to be suspended mounted on the rigid connection device from falling from the air and causing danger, a flexible connection device rope is additionally provided. When the rigid connection device is damaged, the flexible connection device rope undertakes the function of suspending the device. However, when the rigid connection device is intact, the flexible connection device rope only connects the UAV body and the device to be suspended and does not play a role.

[0051] In an embodiment of the present disclosure, the rope is configured to pass through the hollow cavities of the first connecting rod 2, the second connecting rod 3, and the third connecting rod 4, and then one end is connected to the bottom crossbar 1 of the UAV and the other end is connected to the device to be suspended.

[0052] Specifically, since the first connecting rod 2, the second connecting rod 3, the third connecting rod 4, and the mounting rod 5 are all configured as hollow rods, the flexible connection device rope of the UAV suspension system can be arranged inside the hollow cavities of the first connecting rod 2, the second connecting rod 3, the third connecting rod 4, and the mounting rod 5. This arrangement can save space, facilitate connection with the device to be suspended, and prevent the rope of the flexible connection device from getting entangled when not connected to the device to be suspended, thus affecting the working efficiency.

[0053] In an embodiment of the present disclosure, the third connecting rod 4 is configured to be connected to the middle of the mounting rod 5. There are two ropes. One rope is configured to pass through one end of the mounting rod 5 and then be connected to the device to be suspended, and the other rope is configured to pass through the other end of the mounting rod 5 and then be connected to the device to be suspended.

[0054] Specifically, the third connecting rod 4 is perpendicular to the mounting rod 5 and fixedly connected to the middle of the mounting rod 5. The flexible connection device rope is provided with two ropes. Both ropes are fixedly connected to the bottom crossbar 1 of the UAV and reach the mounting rod 5 along the hollow cavities of the first connecting rod 2, the second connecting rod 3, and the third connecting rod 4. One rope passes through one end of the mounting rod 5 and is connected to the device to be suspended, and the other rope passes through the other end of the mounting rod 5 and is connected to the device to be suspended. This arrangement enables the device to be suspended to be not only fixedly connected to the rigid connection device to ensure the stability of the suspended device during the flight of the UAV, but also connected to the two ropes of the flexible connection device to prevent the suspended device from detaching from the rigid connection device and falling during the flight of the UAV, thus ensuring the safety of the suspended device.

[0055] An unmanned aerial vehicle (UAV) suspension system provided by the present disclosure. Since this UAV suspension system adopts a mounting method combining hard connection and soft connection, the hard connection device can effectively prevent the UAV from shaking when braking or encountering other resistances during movement, thereby affecting the normal operation of the device to be mounted. When the hard connection device is damaged during UAV flight, the soft connection device mounts the device to be mounted at this time to prevent the device to be mounted from falling due to the damage of the hard connection device.
