Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, and in particular to a device for adjusting the hanging tension of an unmanned aerial vehicle. 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. The function of the suspension equipment is to lift the cargo. Due to the different shapes of the cargo or the uneven distribution of the center, the suspension rope of the suspension equipment needs to be connected to each point of the cargo. At this time, the suspension rope cannot be completely straightened, so it is necessary to use the tension adjustment device to adjust the tension of the suspension rope. The adjustment principle is to tighten the suspension rope to make it tight. However, although the traditional tension adjustment device can tighten the suspension rope, the suspension rope will deform, so it is easy to cause wear between the tension adjustment device and the tension adjustment device, affecting the service life. In addition, most traditional tension adjustment devices cannot be separated from the suspension rope, which makes installation and disassembly inconvenient. Utility Model Content

[0004] The utility model aims to solve the problem that the above-mentioned tension adjustment device is easy to wear the hanging rope during use and is convenient to install and disassemble, and to provide a drone hanging tension adjustment device, which has the advantages of easy installation and disassembly, adaptability to the use of hanging ropes of different thicknesses, and strong adjustment stability.

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

[0006] A drone hanging tension adjustment device comprises a shell, both ends of the shell are provided with wire holes, and the hanging rope of the drone passes through the tension adjustment device through the wire holes, and a limiting mechanism is installed on one side of the shell close to the wire holes, and an adjustment column is installed between two limiting mechanisms, and the adjustment column is controlled by a driving motor to move in a direction perpendicular to the hanging rope;

[0007] The limiting mechanism comprises at least two limiting posts, and the hanging rope is located between the limiting posts when passing through the wire hole.

[0008] Preferably, the adjusting column is mounted on a sliding seat, the sliding seat is threadedly mounted on a threaded screw, and the end of the threaded screw is connected to the motor shaft of the driving motor.

[0009] Preferably, guide rails parallel to the threaded screw are installed on both sides of the threaded screw, and the sliding seat is slidably installed on the guide rails.

[0010] Preferably, the limiting mechanism comprises a support plate, a plurality of limiting columns are provided and evenly distributed on the surface of the support plate, and a telescopic structure is installed at the bottom of the limiting column and can be telescopic on the surface of the support plate.

[0011] Preferably, the surface of the support plate is penetrated with telescopic holes having the same number as the limiting columns, a base is provided at the bottom of the support plate, and one end of the limiting column passes through the support plate and is connected to the base via a reset spring.

[0012] Preferably, a tension sensor module and a power supply module are also installed in the shell, and a power supply interface is also provided on the outer wall of the shell.

[0013] Preferably, the shell includes an upper shell cover and a lower shell cover, one end of the upper shell cover and the lower shell cover are hinged, and the other end is connected by a snap, and the wire hole is composed of two semicircular through holes on the surface of the upper shell cover and the lower shell cover.

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

[0015] 1. The utility model adjusts the tension of the hanging rope by pushing the hanging rope to deform through the movement of the adjusting column, and the hanging rope passes through the limiting column close to the wire hole. The two limiting columns can limit the left and right movement of the hanging rope when the deformation occurs, thereby avoiding friction between the hanging rope and the wire hole and preventing the hanging rope from being damaged.

[0016] 2. The utility model realizes the movement of the adjustment column by rotating the threaded screw, and the threaded screw is controlled by the driving motor to rotate. In this way, after the adjustment column moves to the appropriate position, the driving motor stops working, and the adjustment column will not return or shake, thereby increasing the adjustment stability. In addition, the housing of the tension adjustment device is composed of an upper shell cover and a lower shell cover that can be opened and closed, which is convenient for clamping on the hanging rope and convenient for installation and disassembly.

[0017] 3. The utility model arranges the limiting mechanism into a plurality of retractable limiting columns. When the tension adjusting device clamps the hanging rope, the hanging rope can retract some limiting columns according to the diameter, and the other limiting columns will be located at both ends of the hanging rope for limiting, thereby meeting the use of hanging ropes of different diameters.

DETAILED DESCRIPTION

[0022] 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.

[0023] like Figure 2 As shown, a drone hanging tension adjustment device includes a shell, both ends of the shell are provided with wire holes 3, and the hanging rope of the drone passes through the tension adjustment device through the wire holes 3. A limiting mechanism 6 is also installed on one side of the shell close to the wire holes 3, and an adjustment column 7 is installed between two limiting mechanisms 6. The adjustment column 7 is controlled by a driving motor 10 to move in a direction perpendicular to the hanging rope. The wire holes 3 are used to facilitate the hanging rope to pass through the entire tension adjustment device, and when the hanging rope passes through, the two limiting mechanisms 6 and the adjustment column 7 form an adjustment mechanism, for example Figure 2 In the embodiment, the adjusting column 7 can move left and right, and the hanging rope passes through up and down, so that when the adjusting column 7 moves, the hanging rope between the limiting mechanism 6 will be bent, so that the loose hanging rope can be tightened, and the adjusting column 7 is controlled by the driving motor 10 to facilitate control.

[0024] The limiting mechanism 6 includes at least two limiting columns 17, and the hanging rope is located between the limiting columns 17 when passing through the Susou wire hole 3. Since the limiting mechanism 6 is close to the wire hole 3 and the adjusting column 7, when the hanging rope between the limiting mechanism 6 is bent, the part of the hanging rope located in the wire hole 3 is limited by the two limiting columns 17 and does not contact the wire hole 3, thereby achieving the effect of reducing the wear of the hanging rope.

[0025] In order to facilitate the control and adjustment stability, the adjustment column 7 is installed on the sliding seat 8, and the sliding seat 8 is threadedly installed on the threaded screw 11. The end of the threaded screw 11 is connected to the motor shaft of the driving motor 10. The adjustment column 7 drives the threaded screw 11 to rotate through the driving motor 10 to realize the movement of the sliding seat 8, thereby bending the hanging rope. The purpose of using the threaded screw 11 to achieve transmission here is that when the driving motor 10 stops working, the position of the sliding seat 8 will not change, which is convenient for fixing the adjusted tension. It only needs the threaded screw 11 to have denser teeth, so that the sliding seat 8 can be more accurately controlled in displacement. Guide rails 9 parallel to the threaded screw 11 are also installed on both sides of the threaded screw 11, and the sliding seat 8 is slidably installed on the guide rails 9. The guide rails 9 are for the sliding seat 8 to move more stably.

[0026] like Figure 3 As shown, the limiting mechanism 6 includes a support plate 14, and a plurality of limiting columns 17 are evenly distributed on the surface of the support plate 14. A telescopic structure is installed at the bottom of the limiting column 17, which can be telescopic on the surface of the support plate 14. A plurality of limiting columns 17 are provided and can be telescopic. In this way, when the diameter of the hanging rope is large, more limiting columns 17 can be pressed down to retract the support plate 14. When the diameter is small, fewer limiting columns 17 can be pressed down to retract the support plate 14. Regardless of whether the diameter is large or small, the remaining limiting columns 17 can still play a limiting role. Therefore, the limiting mechanism 6 is not affected by the thickness of the hanging rope. The surface of the supporting plate 14 is penetrated with telescopic holes 16 with the same number as the limiting columns 17. A base 15 is set at the bottom of the supporting plate 14. One end of the limiting column 17 passing through the supporting plate 14 is connected to the base 15 through a reset spring 18. The telescopic movement of the limiting column 17 is achieved by the reset spring 18.

[0027] like Figure 2 As shown, a tension sensor module 13 and a power supply module 12 are also installed in the shell, and a power supply interface 4 is also provided on the outer wall of the shell. The tension sensor module 13 can detect the tension of the hanging rope, and the power supply module 12 provides power for the entire device. The power supply interface 4 is convenient for connecting an external power supply or an external controller.

[0028] like Figure 1 As shown, the shell includes an upper shell cover 1 and a lower shell cover 2. One end of the upper shell cover 1 and the lower shell cover 2 are hinged, and the other end is connected by a buckle 5. The wire hole 3 is composed of two semicircular through holes on the surfaces of the upper shell cover 1 and the lower shell cover 2. The shell adopts a hinged manner of the upper shell cover 1 and the lower shell cover 2, which is convenient for opening the shell, thereby facilitating the clamping of the hanging rope, which can facilitate the installation and disassembly of the entire tension adjustment device.

[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.

[0030] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
