Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to an anti-sway hanging device for unmanned aerial vehicles. 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] However, when traditional UAV's hanging equipment is flying at high altitudes, it is easily affected by crosswinds, resulting in poor stability and thus accidents. If the hanging equipment is rigidly connected to the UAV, then when affected by crosswinds, the heavy object will swing due to the crosswind, thereby transmitting the swinging force to the UAV body, causing the UAV to fly unstably. If a flexible connection is used, the effect of resisting crosswinds will be far less than that of a rigidly connected hanging equipment. Therefore, traditional UAV's hanging equipment still has certain defects when used. Utility Model Content

[0004] The utility model aims to provide a UAV anti-sway hanging device in order to solve the problem that the UAV is easily swayed by crosswind when transporting goods. The device has the advantages of good stability when hanging heavy objects and is not easy to affect the flight of the UAV.

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

[0006] A drone anti-sway hanging device comprises a mounting bracket connected to the drone, a connecting foot is arranged at the edge of the mounting bracket, a hanging rope is installed on the connecting foot, and the hanging rope is flexibly connected to the connecting foot, and a hanging hook is installed at the free end of the hanging rope, and an anti-sway mechanism is also installed on the hanging rope, and the anti-sway mechanism comprises a plurality of auxiliary counterweight blocks, and the auxiliary counterweight blocks are sequentially arranged with intervals from top to bottom, the intervals are connected by connecting ropes, and the center lines of all the auxiliary counterweight blocks coincide with the center line of the hanging rope.

[0007] Preferably, the auxiliary counterweight block is a spherical structure.

[0008] Preferably, a mounting screw hole is provided on the auxiliary counterweight block, and a mounting screw head is provided on the connecting rope, and the mounting screw head matches the mounting screw hole.

[0009] Preferably, at least three connecting legs are provided, evenly distributed on the edge of the mounting bracket, and the number of hanging ropes corresponds to the number of connecting legs.

[0010] Preferably, a fixed pulley is installed on the connecting foot, and the end of the hanging rope away from the hanging hook passes through the fixed pulley and is connected to the main counterweight block. A supporting foot is arranged at the bottom of the mounting bracket, and the main counterweight block is located at the center of the supporting foot.

[0011] Preferably, a connecting hole is provided on one side of the main counterweight block, and one end of the hanging rope passes through the connecting hole to install a buckle, and the length of the hanging rope is adjusted by the buckle.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The utility model has a flexibly connected hanging rope and a mounting bracket. Even if the hanging object swings, it will not affect the flight stability of the UAV. In addition, an anti-sway mechanism is arranged on the hanging rope to reduce the force of the swing by using independent and serially connected auxiliary counterweights. The principle of reducing the swing is that the centers of the auxiliary counterweights are consistent and independent of each other. Even if the hanging hook below swings, the swing force will first be transmitted to the auxiliary counterweight at the bottom. The auxiliary counterweight is pulled by the auxiliary counterweight on the upper layer to maintain the center in a straight line. The pulling force between the two auxiliary counterweights is used to offset the swing force, thereby achieving an anti-sway effect. Without considering the load-bearing capacity of the UAV, the more auxiliary counterweights are set, the better the anti-sway effect.

[0014] 2. The utility model connects the top end of the hanging rope through the fixed pulley to the main counterweight block, so that when there is no hanging weight, the main counterweight block can pull down the hanging rope to lift the hanging hook off the ground, which is convenient for parking the UAV, and the fixed pulley and the main counterweight block are used to realize a flexible connection between the hanging rope and the mounting bracket.

DETAILED DESCRIPTION

[0019] 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.

[0020] like Figure 1 and Figure 2 As shown, an anti-sway hanging device for a drone comprises a mounting bracket 1 connected to a drone, a connecting foot 2 is arranged at the edge of the mounting bracket 1, a hanging rope 4 is installed on the connecting foot 2, and the hanging rope 4 is flexibly connected to the connecting foot 2, a hanging hook 7 is installed at the free end of the hanging rope 4, and an anti-sway mechanism 5 is also installed on the hanging rope 4, and the anti-sway mechanism 5 comprises a plurality of auxiliary counterweight blocks 11, and the auxiliary counterweight blocks 11 are arranged with intervals from top to bottom in sequence, and the intervals are connected by a connecting rope 14, and the center lines of all the auxiliary counterweight blocks 11 coincide with the center line of the hanging rope 4. A plurality of screw holes are arranged on the mounting bracket 1 to fix the mounting bracket 1 to the bottom of the drone, and the hanging rope 4 on the mounting bracket 1 is used to suspend heavy objects, and the hanging rope 4 is fixed to the heavy object through the hanging hook 7, and the fixing method is various. In this application, only the hanging hook 7 is taken as an example, and other fixing methods are not repeated.

[0021] In order to prevent the UAV from shaking due to the influence of crosswind when transporting goods at high altitude, the hanging rope 4 is first set up. The hanging rope 4 is connected to the connecting foot 2 in a flexible connection manner. In this way, even if the heavy object at the bottom of the hanging rope 4 swings due to crosswind, the swing force is not easily transmitted to the UAV body. This step first ensures the stability of the UAV flight. Secondly, the hanging rope 4 is designed to prevent swing, and the anti-swing effect is achieved through the anti-swing mechanism 5. The specific principle is as follows: the anti-swing mechanism 5 adopts multiple auxiliary counterweight blocks 11, and the auxiliary counterweights The blocks 11 are arranged at intervals and independently connected by connecting ropes 14, so that when the lowest auxiliary counterweight block 11 is swung, it will not affect the upper auxiliary counterweight block 11. After the hanging rope 4 suspends the heavy object, all the connecting ropes 14 are straightened by gravity. At this time, the center lines of the auxiliary counterweight blocks 11 are consistent with the center lines of the hanging ropes 4. In this case, when the auxiliary counterweight blocks 11 of the lower layer swing left and right, the swinging force will also be offset by the tension of the connecting ropes 14 of the upper auxiliary counterweight blocks 11, thereby achieving the effect of preventing the entire anti-sway mechanism 5 from swinging.

[0022] In order to reduce wind resistance, Figure 2As shown, the auxiliary counterweight block 11 is a spherical structure. The auxiliary counterweight block 11 with a spherical structure can reduce resistance regardless of whether the drone is flying up and down or flying horizontally, and also indirectly reduces the swing caused by crosswind. The auxiliary counterweight block 11 is provided with a mounting screw hole 12, and a mounting screw head 13 is provided on the connecting rope 14. The mounting screw head 13 matches the mounting screw hole 12. Without considering the load of the drone, the more auxiliary counterweight blocks 11 there are, the less likely the upper layer will be affected by the swing. However, in actual application, the auxiliary counterweight block 11 has a certain weight and will occupy a part of the load capacity of the drone. Therefore, the auxiliary counterweight block 11 is designed to be a structure that is easy to disassemble, and is easy to install by means of threaded connection. In this way, the appropriate number of auxiliary counterweight blocks 11 can be customized to be used as the anti-sway mechanism 5.

[0023] In order to ensure the stability of the hanging rope 4 suspending the heavy object, the connecting feet 2 are provided with at least three, evenly distributed on the edge of the mounting bracket 1, and the number of the hanging rope 4 corresponds to the number of the connecting feet 2, preferably four connecting feet 2, such as Figure 3 As shown, the four hanging ropes 4 are subjected to balanced forces in the four directions of front, back, left, and right. A fixed pulley 3 is installed on the connecting foot 2, and the end of the hanging rope 4 away from the hanging hook 7 passes through the fixed pulley 3 and is connected to the main counterweight 6. A supporting foot 8 is arranged at the bottom of the mounting bracket 1, and the main counterweight 6 is located at the center of the supporting foot 8. The fixed pulley 3 is used to change the direction of the hanging rope 4. The hanging rope 4 is essentially connected to the main counterweight 6. The main counterweight 6 is not directly installed on the mounting bracket 1, so the hanging rope 4 is flexibly connected to the mounting bracket 1, and the main counterweight 6 is used to provide downward gravity. When a heavy object is suspended at the bottom of the hanging rope 4, the up and down shaking will be offset by the main counterweight 6. When the hanging rope 4 does not suspend a heavy object, the counterweight 6 can pull down the hanging rope 4, lift the hanging hook 7, leave the ground, and support the drone by the supporting foot 8, so that the drone can be stored when it is idle.

[0024] A connection hole 9 is provided on one side of the main counterweight block 6, and one end of the hanging rope 4 passes through the connection hole 9 to install a buckle 10, and the length of the hanging rope 4 is adjusted by the buckle 10. The hanging ropes 4 are independent of each other. When hanging a special-shaped heavy object, the length of the hanging rope 4 can be adjusted by the buckle 1 to avoid the situation that the hanging rope 4 cannot be straightened after the hanging hook 7 is fixed on the special-shaped heavy object.
