Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology, specifically relating to a suspension mechanism and a UAV system. Background Technology

[0002] Drones are widely used in power line inspection, disaster relief, construction, and logistics. With the improvement of drone payload capacity and endurance, drone-based hoisting and aerial operations have become an important development direction. In existing drone hoisting mechanisms, the boom is directly fixed to the fuselage. When the drone encounters resistance during flight, the boom's impact resistance is poor, and the connection point between the boom and the drone is prone to breakage. Utility Model Content

[0003] The purpose of this utility model is to disclose a suspension mechanism to solve the technical problem of poor impact resistance when the boom is used for drone mounting in the prior art.

[0004] To achieve the above objectives, the first aspect of this utility model discloses a suspension mechanism for a drone, comprising:

[0005] Mounting device for mounting to the fuselage of a drone;

[0006] A buffer structure, movably mounted on the mounting body, is used to absorb vibration;

[0007] The boom is rotatably connected to the buffer structure at one end;

[0008] A hook, located at the other end of the boom, is used to hang items.

[0009] As an optional implementation, the buffer structure includes a damper and a first elastic element. The damper is slidably disposed relative to the mounting body, with one end rotatably disposed with the boom and the other end connected to the first elastic element. The first elastic element is used to undergo elastic deformation when the damper slides relative to the mounting body.

[0010] As an optional implementation, the buffer structure further includes a connecting frame connected between the other end of the damper and the first elastic member.

[0011] As an optional implementation, the suspension mechanism further includes a limiting structure connected to the buffer structure, which is used to limit the rotation range of the boom relative to the buffer structure.

[0012] As an optional implementation, the limiting structure includes limiting plates and a second elastic member disposed opposite to each other on both sides of the buffer structure. The limiting plates are used to restrict the rotation of the boom relative to the buffer structure in a first direction. The second elastic member is connected between the buffer structure and the boom and is used to restrict the rotation of the boom relative to the buffer structure in a second direction, wherein the first direction and the second direction are opposite.

[0013] As an optional implementation, the limiting plate includes a connecting portion and a limiting portion arranged at an obtuse angle, the connecting portion being connected to the buffer structure, and the limiting portion being inclined in a direction away from the axis of the buffer structure.

[0014] As an optional implementation, the boom is a telescopic boom.

[0015] As an optional implementation, the suspension mechanism further includes rollers, which are located at one end of the boom connected to the hook.

[0016] A second aspect of this utility model discloses an unmanned aerial vehicle (UAV) system, comprising:

[0017] Drones;

[0018] The aforementioned suspension mechanism is mounted on the UAV.

[0019] As an optional implementation, the mounting body and the drone are detachably connected.

[0020] Compared with the prior art, the advantages of the suspension mechanism and the drone of this utility model are as follows:

[0021] When the suspension mechanism of this utility model is applied to suspend items on a drone, it has a buffer structure that can be movably set relative to the mounting body. When an item is hung on the hook and when the drone is in flight, the impact force (vibration caused by air resistance) on the boom is transmitted to the buffer structure, which absorbs the energy of the vibration. The impact force generated by the vibration is gradually consumed, ensuring the stability of the boom in suspending the item, improving the boom's impact resistance, and reducing the interference of the item's load on the drone's flight, thus ensuring flight stability.

[0038] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0039] In existing technologies, the methods for suspending items using drones typically include the following:

[0040] (1) Rigid suspension structures, such as rigid connecting rods or rigid hooks, are directly installed on the fuselage of the UAV. When the rigid suspension structure is fixed with a load, the UAV, the suspension structure and the items suspended on the suspension structure are subjected to resistance. Since the suspension structure and the UAV are rigidly connected, the suspension structure has poor impact resistance and cannot adapt to complex environments.

[0041] (2) Flexible suspension structures, such as rope suspension, are commonly used in logistics and transportation drones. They use ropes to transport goods. Since ropes can bend, they have a certain buffering effect. However, during the flight of the drone, there is a serious swaying and insufficient load stability, which affects the normal flight in strong winds.

[0042] (3) Electrically controlled hook-type structure, such as installing an electromagnetic hook or electric gripper on the bottom of the drone. This type of hanging structure has high control accuracy, but the mechanism is complex and heavy, which reduces the drone's flight time. Moreover, the manufacturing cost of this type of structure is high, which increases the cost of using the drone.

[0043] To provide a hanging mechanism that can stably support items and has cushioning properties, please refer to [link / reference needed]. Figures 1 to 4 The first embodiment of this application provides a suspension mechanism 100 applied to a drone 70, including a mounting body 10, a buffer structure 20, a boom 30, and a hook 40.

[0044] Please refer to Figure 1 The mounting body 10 is used to install onto the fuselage of the drone 70; the buffer structure 20 is movably mounted on the mounting body 10 to absorb vibration; one end of the boom 30 and the buffer structure 20 are rotatably set; the hook 40 is located at the other end of the boom 30 for hanging items.

[0045] When the aforementioned sling mechanism 100 is used to suspend items on a drone, it is equipped with a buffer structure 20 that is movable relative to the mounting body 10. When items are hung on the hook 40 and when the drone 70 is in flight, the impact force (vibration caused by air resistance) on the boom 30 is transmitted to the buffer structure 20, which absorbs the energy of the vibration. The impact force generated by the vibration is gradually consumed, ensuring the stability of the boom 30 in suspending items, improving the impact resistance of the boom 30, and reducing the interference of the load of the items on the flight of the drone 70, thus ensuring flight stability.

[0046] It should be noted that when the sling mechanism 100 of this embodiment is installed on the bottom wall of the drone 70, it is installed on the bottom wall of the drone body to have sufficient connection area with the drone 70, while avoiding affecting the normal use of the drone 70's landing gear and other structures.

[0047] Please see Figure 1 and Figure 2This is a schematic diagram of the buffer structure 20 according to an embodiment of the present invention. The buffer structure 20 includes a damper 21 and a first elastic member 22. The damper 21 is slidably disposed relative to the mounting body 10, with one end rotatably disposed with the boom 30, and the other end connected to the first elastic member 22. The first elastic member 22 is used to undergo elastic deformation when the damper 21 slides relative to the mounting body 10. Thus, when an object is hung on the boom 30 and subjected to an impact force, the impact force is transmitted to the damper 21, causing the damper 21 to slide relative to the mounting body 10 and compressing the first elastic member 22. The compression or stretching of the first elastic element 22 converts mechanical energy into elastic potential energy for temporary storage, preventing the impact force from being directly transmitted to the fuselage. At the same time, the resistance in the damper 21 converts the mechanical energy of the vibration into heat energy (or other forms of energy) and dissipates it, allowing the vibration amplitude to decrease rapidly. Thus, the damper 21 and the first elastic element 22 jointly absorb the vibration energy, ensuring the impact resistance of the UAV 70 and preventing the impact force from being transmitted to the fuselage, affecting the stability of the UAV flight, and affecting the connection strength of the connection point between the suspension mechanism 100 and the UAV.

[0048] In one embodiment, when setting the connection between the first elastic element 22 and the damper 21, one end of the first elastic element 22 may be held against the mounting body 10 and the other end may be hooked onto the damper 21, or the other end of the first elastic element 22 may also be in contact with the damper 21. When the damper 21 slides relative to the mounting body 10, the extension and retraction of the first elastic element 22 can be achieved.

[0049] The first elastic element 22 can be a spring or a multi-segment elastic structure.

[0050] Specifically, in order to facilitate the connection between the damper 21 and the first elastic member 22, the buffer structure 20 of this embodiment also includes a connecting frame 23. The connecting frame 23 is connected between the other end of the damper 21 and the first elastic member 22, and is slidably disposed with respect to the mounting body 10. In this way, by setting the connecting frame 23, when the damper 21 slides relative to the mounting body 10, it can drive the connecting frame 23 to slide relative to the mounting body 10, and at the same time, it can drive the first elastic member 22 to extend and retract. This facilitates the assembly between the damper 21 and the first elastic member 22.

[0051] Furthermore, when installing the damper 21 and the first elastic member 22 through the connecting frame 23, the first elastic member 22 can be positioned in the direction of movement of the damper 21, and the connecting frame 23 can be connected to the other end of the damper 21. One end of the first elastic member 22 is connected to the connecting frame 23, and the other end abuts against the end of the damper 21 that passes through the mounting body 10. That is, at this time, the axial direction of the first elastic member 22 is located in the extension direction of the axial direction of the damper 21. Alternatively, in another embodiment, the first elastic member 22 and the damper 21 can be arranged in parallel, which can also achieve the effect of the first elastic member 22 being driven by the damper 21 to achieve extension and contraction.

[0052] Specifically, please refer to Figure 2 In this embodiment, the first elastic element 22 and the damper 21 are installed in a parallel manner. This shortens the installation length along the axis of the damper 21, thereby reducing the length of the entire hanging mechanism 100 along the axis of the boom 30, thus reducing the degree of freedom of the entire hanging mechanism 100 and ensuring the overall structural strength.

[0053] Furthermore, when the first elastic element 22 and the damper 21 are arranged side by side, in order to ensure the stability of the damper 21 sliding relative to the mounting body 10, this embodiment provides at least two first elastic elements 22, and the spacing between any two adjacent first elastic elements 22 is set to be the same, so as to receive the same amount of driving force applied from the damper 21. For example, when two first elastic elements 22 are provided, the two first elastic elements 22 are located on both sides of the damper 21 in the radial direction. When three, four or more dampers 21 are provided, the multiple first elastic elements 22 are equally spaced around the outer periphery of the damper 21.

[0054] In this embodiment, two first elastic elements 22 are used as an example for explanation. By setting two first elastic elements 22, the stable sliding of the damper 21 is ensured, and the structural simplicity of the entire buffer structure 20 is also ensured. This facilitates the assembly of the entire buffer structure 20, reduces the assembly cost of the components, and also ensures the vibration absorption effect.

[0055] Specifically, in this embodiment, the connecting frame 23 is located at the other end of the damper 21, and the middle part of the connecting frame 23 is connected to the damper 21. For example, the two can be connected by bolts. Each end of the connecting frame 23 is provided with one end of the first elastic member 22 abutting against each other, thus realizing the abutment between the connecting frame 23 and the first elastic member 21. Specifically, each end of the connecting frame 23 is provided with a first guide post 231, and one end of the first elastic member 22 is sleeved on the first guide post 231. Further, the mounting body 10 is provided with a second guide post 11, and the other end of the first elastic member 22 is sleeved on the second guide post 11. Thus, through the cooperation of the two positioning posts, the first elastic member 22 is positioned and installed, so that when the damper 21 slides relative to the mounting body 10, the connecting frame 23 drives the first elastic member 22 to stretch and shorten. In other embodiments, it can also be achieved by hooking the two ends of the first elastic member 22 onto the connecting frame 233 and the mounting body 10 respectively.

[0056] In this embodiment, the connecting frame 23 is slidably disposed relative to the mounting body 10, so as to limit the linear sliding mode of the damper 21 relative to the mounting body 10, and at the same time limit the first elastic member 22 to extend and retract in the linear direction.

[0057] Specifically, to achieve the sliding arrangement of the connecting frame 23 relative to the mounting body 10, a groove 241 can be provided on one of the connecting frame 23 and the mounting body 10, and a slide rail 25 can be provided on the other. Thus, the buffer structure 20 of this embodiment also includes a slider 24 and a slide rail 25. The slider 24 is provided with a groove 241 and is connected to the connecting frame 23. The slide rail 25 is provided on the mounting body 10, so that when the damper 21 slides relative to the mounting body 10, it can drive the connecting frame 23 to slide relative to the slide rail 25.

[0058] Please see Figure 2 The above is a schematic diagram of the structure of the mounting body 10 in this embodiment of the present invention. The mounting body 10 is a ring structure, which facilitates the sliding of the damper 21, the installation of the slide rail 25, and the installation onto the body of the drone 70.

[0059] Specifically, the mounting body 10 includes a first mounting plate 12 and a second mounting plate 13 arranged opposite to each other. The two first mounting plates 12 and the two second mounting plates 13 enclose a mounting space 14. The connecting frame 23 and the first elastic element 22 are both arranged in the mounting space 14. One first mounting plate 12 is used for the damper 21 to slide, and the other first mounting plate 12 is connected to the fuselage. The inner walls of the two second mounting plates 13 are respectively used to install a slide rail 25. In this way, a ring-shaped mounting body 10 structure is realized, and the overall structural strength of the mounting body 10 can be guaranteed.

[0060] Please see Figure 3Since the boom 30 is rotatably mounted relative to the damper 21, to prevent the boom 30 from rotating too much relative to the damper 21, the suspension mechanism 100 in this embodiment also includes a limiting structure 50. The limiting structure 50 is connected to the buffer structure 20 and is used to limit the rotation range of the boom 30 relative to the buffer structure 20. Thus, during flight, the limiting structure 50 can limit the amplitude of the swing of the object driven by the boom 30, preventing the swing range from being too large and affecting the stability of the flight. For example, in one embodiment, limiting blocks can be provided along the swing direction of the boom 30. When the boom 30 touches the limiting block, it means that the boom 30 can no longer swing in that direction.

[0061] Specifically, the limiting structure 50 in this embodiment includes limiting plates 51 and a second elastic member 52 disposed opposite to each other on both sides of the buffer structure 20. The limiting plates 51 are connected to one end of the damper 21 connected to the boom 30, and are used to limit the rotation of the boom 30 relative to the buffer structure 20 along the first direction a. For example... Figure 3 The direction indicated by arrow a; the second elastic element 52 is connected between the buffer structure 20 and the boom 30, and is used to limit the rotation of the boom 30 relative to the buffer structure 20 along the second direction b, for example Figure 3 The direction indicated by arrow b is as follows, where the first direction and the second direction b are opposite. Specifically, the two ends of the second elastic element 52 are hooked onto the damper 21 and the boom 30 respectively, so that it can rotate relative to the damper 21 and the boom 30. That is, the limiting structure 50 in this embodiment combines a fixed mechanical limiting method and a movable elastic limiting method. When the boom 30 moves towards the limiting plate 51, touching the limiting plate 51 indicates that the rotation of the boom 30 along the first direction a has stopped. At the same time, since the limiting plate 51 is only connected to the damper 21, when the boom 30 moves towards the second direction a... When rotating towards b, it interferes with the rotation of the boom 30. When rotating along the second direction b, the second elastic element 52 can be compressed, and the compression of the second elastic element 52 has a certain range, so that the boom 30 has a certain amount of movement along the second direction b. When the drone needs to stop or needs to load items, the boom 30 can rotate in the second direction b to be roughly in a parallel state, thereby avoiding interference with the stopping of the drone. At the same time, the setting of the second elastic element 52 can prevent the boom 30 from being in an overly free state of rotation along the second direction b.

[0062] When the second elastic element 52 is installed, the limiting structure 50 includes two mounting brackets 53. One mounting bracket 53 is installed on the damper 21 and the other mounting bracket 53 is installed on the boom 30. The second elastic element 52 is a spring, and the two ends of the spring are hooked onto one mounting bracket 53 respectively.

[0063] Please see Figure 3In this embodiment, the limiting plate 51 is designed to provide a certain buffer range for the boom 30 along the first direction a. The limiting plate 51 includes a connecting part 511 and a limiting part 512 arranged at an obtuse angle. The connecting part 511 is connected to the buffer structure 20, and the limiting part 512 is inclined away from the axis of the buffer structure 20. Specifically, the connecting part 511 is connected to the end of the damper 21 where the boom 30 is mounted, and the limiting part 512 is inclined away from the axis of the buffer structure 20 (i.e., the damper 21) so that the boom 30 can have a range of motion. When subjected to resistance, the boom 30 can swing within a small amplitude, avoiding a rigid connection between the boom 30 and the mounting body 10, achieving the shock absorption effect of the buffer structure 20, and at the same time avoiding the boom 30 swinging within a large amplitude and affecting the stability of the flight.

[0064] When setting the included angle between the connecting part 511 and the limiting part 512, it can be set to an included angle of 140°, 150°, 155° or 160°.

[0065] Please see Figure 4 The diagram below shows the structure of the hook 40 in this embodiment. The hook 40 adopts a rigid structure, which enables quick hanging of items and prevents items from falling off.

[0066] Understandably, in order to ensure the stability of the hanging of the item, the hook 40 may include multiple hooks, each hook forming a hooking point 41. The item is hung on multiple hooking points 41 at the same time, which ensures the stability of the hanging of the item, prevents the item from falling, and at the same time distributes the weight of the item on multiple hooking points 41, increases the service life of the hook 40 and reduces the risk of breakage.

[0067] In this embodiment, the boom 30 is designed to be telescopic, allowing for length adjustment to ensure sufficient hanging distance while also being able to be folded up for storage. Specifically, the length of the boom 30 can be adjusted by hand before hanging items to suit different height positions of the items.

[0068] Please see Figure 1 and Figure 4 To prevent the drone 70 from taking off and landing, the hoisting mechanism 100 also includes a roller 60. The roller 60 is located at one end of the boom 30 connected to the hook 40. With the setting of the roller 60, when the drone 70 takes off and lands, the roller 60 can contact the ground and roll with the ground, resulting in a small friction force. This avoids the end of the hook 40 from directly contacting the ground, which would cause a large friction force and affect the normal take-off and landing of the drone 70.

[0069] Furthermore, in this embodiment, the mounting body 10, hook 40, mounting frame 53, and connecting frame 23 in the sling mechanism 100 are made of aluminum alloy, and the boom 30 is made of lightweight carbon fiber. This not only ensures the structural strength of the entire sling mechanism 100, but also makes the entire sling mechanism 100 lightweight, thus avoiding affecting the flight path of the UAV.

[0070] The aforementioned hoisting mechanism 100, by configuring the buffer structure 20 to include a damper 21 and a first elastic element 22, combines damping and elastic shock absorption to absorb the impact force of the UAV 70 during hoisting and flight, reducing the impact of the load on the flight stability of the UAV 70. By setting a limiting structure 50 on the damper 21 in the buffer structure 20, the boom 30 can swing with a certain amplitude, while avoiding excessive swing range. By setting a roller 60 at the end of the boom 30, the contact between the roller 60 and the ground reduces the friction between the entire hoisting mechanism 100 and the ground, facilitating the take-off and landing of the UAV 70.

[0071] Please see Figures 5 to 8 In the second embodiment, this embodiment also provides an unmanned aerial vehicle (UAV) system 200, including a UAV 70 and the aforementioned sling mechanism 100.

[0072] The sling mechanism 100 and the drone 70 are detachably connected. For example, the mounting body 10 and the drone body can be connected by bolts. The sling mechanism 100 can be disassembled or installed relative to the drone body depending on whether there is a slinging need. Alternatively, the sling mechanism 100 can be installed on the drone body of different models to adapt to different slinging platforms.

[0073] The aforementioned unmanned aerial vehicle (UAV) system 200 has a detachable sling mechanism 100 on the fuselage of the UAV 70. The sling mechanism 100 can be disassembled or installed depending on whether slinging is required. At the same time, the sling mechanism 100 can be installed on different UAV 70 platforms and is compatible with different models, thus having practicality.

[0074] Among them, the different usage states of the suspension mechanism 100 on the UAV 70 are as follows: Figures 5 to 8 As shown, where, Figure 5 This is a schematic diagram showing the drone 70 and the sling mechanism 100 positioned on the ground.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
