Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, and in particular to a dual-unmanned aerial vehicle hanging device. Background Art

[0002] The full name of UAV is unmanned aerial vehicle, which is a reusable aircraft that is controlled by radio remote control or autonomous program and has no pilot on board. UAVs need to maintain sufficient load capacity and stability to complete their tasks. The application scenarios of UAVs are mostly short-distance transportation or monitoring. During transportation, UAVs are usually equipped with hanging equipment to suspend the transported objects, thereby achieving the purpose of air transportation.

[0003] Suspension equipment usually refers to the device used to hoist or mount various items or equipment on drones. This type of suspension equipment allows drones to perform various tasks, such as material transportation, equipment installation, filming, etc. Sometimes the weight of the cargo is too heavy, which will cause a single drone to be unable to lift the cargo, so two drones will be selected to lift the cargo together. Therefore, the suspension equipment must not only meet the requirements of cargo lifting, but also the stability when connecting two drones. When using two drones, it is difficult to ensure that the weight of the cargo is evenly distributed on the two drones. Therefore, even if the drone's control system can solve the problem of synchronous flight, the drone will shake due to uneven weight. Traditional suspension equipment is easy to transmit the shaking of the drone end to the cargo, causing the cargo to swing, thereby affecting the stability of the suspension. Utility Model Content

[0004] The utility model provides a dual UAV hanging device in order to solve the problem that the shaking of the UAVs is easily transmitted to the cargo itself and affects the hanging stability when the dual UAVs are hung. The device has the advantages of isolating the shaking of the UAV ends, ensuring the stability of the hung objects and having stronger hanging stability.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A dual UAV hanging device, comprising a connecting support mechanism and a hanging mechanism, wherein two connecting support mechanisms are provided and symmetrically distributed, and are used to connect UAVs respectively, and the hanging mechanism is installed between the two connecting support mechanisms;

[0007] The connecting support mechanism includes a first bracket and a second bracket, both of which are U-shaped structures, wherein the first bracket is connected to the second bracket via a first rotating shaft, so that the second bracket can be horizontally flipped, and the second bracket is connected to the hanging mechanism via a second rotating shaft, so that the hanging mechanism can be vertically flipped;

[0008] The hanging mechanism comprises a connecting seat and a plurality of hanging arms installed on the connecting seat, and a hanging hook is installed at the free end of each hanging arm.

[0009] Preferably, at least two traction ropes are connected to the first bracket, one end of the traction rope is connected to two sides of the first bracket, and the other end is connected to a connector, the connector is connected to the drone, and the traction rope and the first bracket form a triangular structure.

[0010] Preferably, a fixing column is arranged on the connection seat, one end of each hanging arm is rotatably connected to the fixing column via a rotating collar, and at least three hanging arms are installed.

[0011] Preferably, the hanging arm includes a first arm and a second arm, the first arm and the second arm are rotatably connected via a third rotating shaft, the second arm is fixed on a rotating collar, the third rotating shaft causes the first arm to swing up and down, and a limiting mechanism is also installed at the connection between the first arm and the second arm.

[0012] Preferably, the limiting mechanism includes a limiting plate arranged below the angle between the first arm and the second arm, and the limiting plate is height-adjustable so that when the limiting plate is away from the connection between the two arms, the angle decreases, and when it is close to the connection between the two arms, the angle increases.

[0013] Preferably, a base is installed at the end of the second arm, a screw rod passes through the base, a limit plate is fixed to the bottom end of the screw rod, and the top end of the screw rod passes through the base and is sleeved with a locking button.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The utility model uses a principle similar to a gyroscope to make the innermost hanging mechanism flip up and down and left and right relative to the outermost first bracket. After the hanging mechanism hangs the goods, even if the first bracket deflects left and right and up and down, the hanging mechanism always remains stable. Therefore, after the first bracket is connected to the drone, the shaking of the drone will not cause the hanging goods to shake, especially when two drones are transporting goods, the stability of the hanging is greatly improved.

[0016] 2. The hanging arm of the hanging mechanism of the utility model is arranged as a first arm and a second arm which are rotatably connected, so that the downward distance of the second arm can be adjusted conveniently, and the hanging arm can also rotate around the fixed column as the center, so as to adapt to the connection of goods of different sizes and shapes. Although the hanging arm adopts the rotation mode of the first arm and the second arm, the angle between the two is fixed by adding a limiting mechanism, so as to effectively avoid the tilting of the second arm due to excessive weight, and thus the connection with the goods is more firm.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1 A dual UAV hanging device includes a connecting support mechanism 1 and a hanging mechanism 2. The connecting support mechanism 1 is provided with two and symmetrically distributed, and is used to connect UAVs respectively. The hanging mechanism 2 is installed between the two connecting support mechanisms 1. The connecting support mechanism 1 is provided with two and can be connected to a UAV respectively. The hanging mechanism 2 is connected through the two connecting support mechanisms 1, and the hanging mechanism 2 is used to lift the target cargo.

[0023] like Figure 1 and Figure 2 As shown, the connecting support mechanism 1 includes a first bracket 3 and a second bracket 4, both of which are U-shaped structures, wherein the first bracket 3 is connected to the second bracket 4 through a first rotating shaft 7, so that the second bracket 4 can be flipped horizontally, and the second bracket 4 is connected to the hanging mechanism 2 through a second rotating shaft 8, so that the hanging mechanism 2 can be flipped vertically.

[0024] Since the connecting support mechanisms 1 are all connected to drones, and the drones cannot ensure completely consistent movements, the connecting support mechanisms 1 may shake during flight due to the lack of synchronization of the drones. In order to prevent the shaking force from being transmitted to the hanging mechanism 2, the first bracket 3, the second bracket 4 and the hanging mechanism 2 are formed into a structure similar to a gyroscope. The first rotating axis 7 allows the first bracket 3 and the second bracket 4 to flip horizontally, and the second rotating axis 8 allows the second bracket 4 and the hanging mechanism 2 to flip vertically. Therefore, the hanging mechanism 2 can flip vertically and horizontally relative to the first bracket 3, that is, flip up and down and left and right. After the hanging mechanism 2 hangs the cargo, the gravity is always vertically downward. Therefore, even if the first bracket 3 shakes up and down or left and right, it will not affect the vertical downward gravity of the hanging cargo, thereby ensuring that the hanging cargo is always stable, effectively solving the problem of the shaking of the two drones during flight affecting the hanging cargo.

[0025] The hanging mechanism 2 includes a connecting seat 11 and a plurality of hanging arms 9 installed on the connecting seat 11. A hanging hook 10 is installed at the free end of each hanging arm 9. The hanging mechanism 2 is fixed to the cargo through the hanging hook 10 on the hanging arm 9. A plurality of hanging arms 9 are used in order to connect to each side of the cargo to ensure the stability of the cargo connection.

[0026] like Figure 1 As shown, at least two traction ropes 6 are connected to the first bracket 3, one end of the traction rope 6 is connected to both sides of the first bracket 3, and the other end is connected to the connector 5, the connector 5 is connected to the UAV, the traction rope 6 and the first bracket 3 form a triangular structure, and the connecting support mechanism 1 is connected to the UAV using the traction rope 6, so that the connection with the UAV is in a flexible connection, so the shaking of the UAV will not damage the connecting support mechanism 1, providing a certain shaking redundancy, and using at least two traction ropes 6 to connect is more secure.

[0027] like Figure 2 As shown, a fixed column 12 is provided on the connecting seat 11, and one end of the hanging arm 9 is rotatably connected to the fixed column 12 through a rotating ring 13. At least three hanging arms 9 are installed. Four hanging arms 9 are selected here, and the connection effect is better. Moreover, the hanging arms 9 can be rotated through the rotating ring 13, and each hanging arm 9 can be adjusted to a suitable position. Moreover, the hanging arms 9 rotate independently without affecting each other.

[0028] like Figure 2 and Figure 3As shown, the hanging arm 9 includes a first arm 14 and a second arm 15, the first arm 14 and the second arm 15 are rotatably connected through a third rotating shaft 16, the second arm 15 is fixed on the rotating collar 13, the third rotating shaft 16 makes the first arm 14 swing up and down, and a limiting mechanism is also installed at the connection between the first arm 14 and the second arm 15, the inclination angle of the two arms of the hanging arm 9 can be adjusted, and the hanging arm 9 can be connected to the cargo of special structure by adjusting the inclination angle, because the first arm 14 and the second arm 15 are rotated up and down, the limiting mechanism is used It plays a load-bearing role, so that the downward force of the first arm 14 is supported by the limiting mechanism, and the limiting mechanism includes a limiting plate 18 arranged below the angle between the first arm 14 and the second arm 15. The limiting plate 18 is height-adjustable, and is used to reduce the angle when the limiting plate 18 is away from the connection between the two arms, and increase the angle when it is close to the connection between the two arms. The limiting mechanism fixes the angle between the first arm 14 and the second arm 15 through the limiting plate 18, and the height of the limiting plate 18 is adjustable so as not to affect the angle adjustment between the first arm 14 and the second arm 15.

[0029] It was mentioned above that the limit plate 18 is used to fix the angle, so the following is a detailed description of how to set the limit plate 18 so that its height is adjustable. A base 20 is installed at the end of the second arm 15, and a screw rod 17 passes through the base 20. The limit plate 18 is fixed to the bottom end of the screw rod 17. The top end of the screw rod 17 passes through the base 20 and is sleeved with a locking button 19. The limit plate 18 is raised and lowered by the mutual rotation of the locking button 19 and the screw rod 17.
