Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) manufacturing technology, and more specifically, to a UAV cargo-carrying device. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and their own program control devices. They have no cockpit, but are equipped with autopilots, program control devices, and other equipment. Ground, shipboard, or mothership remote control station personnel track, locate, remotely control, telemetry, and transmit data to them through radar and other equipment. Traditional UAVs have the ability to remotely control the airframe for flight, but with the addition of UAV power for takeoff and landing, UAVs can also carry goods.

[0003] Currently, drones are prone to shaking when carrying cargo, causing the cargo to sway from side to side and shift, making the drone's center of gravity unstable during flight, thus posing a risk of crash and potentially causing economic losses. Utility Model Content

[0004] The purpose of this invention is to provide a drone-borne cargo device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, a drone-borne cargo carrier is provided, comprising a drone connected to and carrying the drone in flight. The cargo carrier includes a track disk mounted on the bottom of the drone. A retractable hydraulic cylinder is disposed at the center of the bottom of the track disk. The movable end of the hydraulic cylinder is movably connected to several clamping arms via a connecting rod. A track groove is formed at the bottom of the track disk. As the hydraulic cylinder extends and retracts, the connecting rod can retract or extend the clamping arms along the direction of the track groove. When the clamping arms gradually retract towards the center of the track disk along the direction of the track groove, the clamping arms will clamp the object to be transported; conversely, when the clamping arms gradually extend outward along the direction of the track groove, the clamping arms will release the object to be transported, completing the unloading.

[0006] The top of the track disk is equipped with bolts, and the bottom of the drone is provided with threaded holes that match the bolts. The side wall of the track disk is provided with tightening straps, which bind the drone and the track disk together.

[0007] Furthermore, the movable end of the hydraulic cylinder is fixedly connected to an adapter, which has a rectangular structure. Both ends of the connecting rod are provided with pins. One end of the connecting rod is movably mounted on the side wall of the adapter via the pin, and the other end of the connecting rod is movably mounted with a sliding arm via the pin. The top end of the sliding arm is slidably mounted in the track groove, and the bottom end of the sliding arm is fixedly connected to the clamping arm. A rubber gasket is provided on the inner side of the clamping arm.

[0008] Furthermore, at least two connecting rods are installed on the side wall of the adapter, and a bottom support plate for supporting the transported object is fixedly connected to the bottom of the clamping arm. The bottom support plate can play a supporting role at the bottom of the object to be transported.

[0009] Furthermore, the track grooves are divided into four groups, with two grooves in each group, and each group of track grooves is set along the diameter of the track disk.

[0010] Furthermore, several of the clamping arms are arranged in a ring around the location of the hydraulic cylinder.

[0011] Furthermore, a T-shaped groove is provided at the bottom of the track plate, which is connected to the track groove. A locking block corresponding to the T-shaped groove is provided at the top of the sliding arm. The sliding arm is suspended on the T-shaped groove through the locking block. In this way, the weight of the transported object can be transferred to the track plate through the sliding arm, which reduces the load on the extension end of the hydraulic cylinder.

[0012] Furthermore, the tightening band is provided with Velcro, and the tightening band includes at least two bands.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] Under the action of the hydraulic cylinder, the connecting rod will bring all the clamping arms together along the direction of the track groove towards the center of the track disk and clamp the object in the center. During this process, the bottom support plate set at the bottom of the clamping arm can play a supporting role at the bottom of the object to be transported. Its purpose is to prevent the object from shaking during transportation, thereby ensuring better stability of the drone during flight.

[0015] By using an adapter to set up multiple linkages, multiple gripping arms can be controlled from multiple directions to clamp the cargo, which can increase the clamping force and make the cargo more stable, thereby improving the stability of the drone during flight transportation.

It should be further understood that the word “comprising” as used in this specification means the presence of the described features, integers, steps, operations, elements, and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0025] Please see Figure 1-5 As shown, a drone-borne cargo carrier is provided, including a drone 1 connected to and carrying the cargo carrier during flight. The cargo carrier includes a track disk 2 mounted on the bottom of the drone 1. A retractable hydraulic cylinder 3 is provided at the center of the bottom of the track disk 2. The movable end of the hydraulic cylinder 3 is movably connected to several clamping arms 5 via a connecting rod 4. A track groove 6 is provided at the bottom of the track disk 2. As the hydraulic cylinder 3 extends and retracts, the connecting rod 4 can bring the clamping arms 5 together or apart along the direction of the track groove 6. When the clamping arms 5 gradually retract towards the center of the track disk 2 along the direction of the track groove 6, the clamping arms 5 will clamp the object to be transported; conversely, when the clamping arms 5 gradually extend outward along the direction of the track groove 6, the clamping arms 5 will release the object to be transported, completing the unloading.

[0026] The top of the track disk 2 is provided with a bolt 7, and the bottom of the drone 1 is provided with a threaded hole that matches the bolt 7. The side wall of the track disk 2 is provided with a tightening strap 8, which binds the drone 1 and the track disk 2 together. The tightening strap 8 is provided with Velcro, and the tightening strap 8 includes at least two straps.

[0027] like Figure 2 and Figure 4As shown, the movable end of the hydraulic cylinder 3 is fixedly connected to an adapter 9, which has a rectangular structure. Both ends of the connecting rod 4 are provided with pins. One end of the connecting rod 4 is movably mounted on the side wall of the adapter 9 via the pins, and the other end of the connecting rod 4 is movably mounted with a sliding arm 10 via the pins. The top end of the sliding arm 10 is slidably mounted in the track groove 6, and the bottom end of the sliding arm 10 is fixedly connected to the clamping arm 5. A rubber gasket is provided on the inner side of the clamping arm 5. The rubber gasket can prevent the clamping arm 5 from applying excessive force during the clamping process and damaging the transported object.

[0028] At least two connecting rods 4 are installed on the side wall of the adapter 9, and a bottom support plate 11 for supporting the transported object is fixedly connected to the bottom of the clamping arm 5. The bottom support plate 11 can play the role of supporting the bottom of the object to be transported.

[0029] By using the adapter 9 to set up multiple links, multiple clamping arms 5 can be controlled from multiple directions to clamp the cargo, which can improve the clamping force and make the cargo more stable, thereby improving the stability of the UAV during flight transportation.

[0030] Among them, such as Figure 4 As shown, the track groove 6 is divided into four groups, with two in each group. Each group of track grooves 6 is set along the diameter of the track disk 2; several clamping arms 5 are arranged in a ring with the position of the hydraulic cylinder 3 as the center.

[0031] like Figure 5 As shown:

[0032] The bottom of the track plate 2 is also provided with a T-shaped groove 13, which is connected to the track groove 6. The top of the sliding arm 10 is provided with a locking block 12 corresponding to the T-shaped groove 13. The sliding arm 10 is suspended on the T-shaped groove 13 through the locking block 12. In this way, the weight of the transported object can be transferred to the track plate 2 through the sliding arm 10, which reduces the load on the extension end of the hydraulic cylinder 3.

[0033] Work process:

[0034] The device is fixedly installed on the bottom of the drone 1 by the bolts 7 on the top of the track disk 2. On this basis, the tightening straps 8 on the side wall of the track disk 2 are wrapped around the drone 1 to achieve a more stable and secure connection.

[0035] The object to be transported is then placed between the clamping arms 5. Then, under the action of the hydraulic cylinder 3, the connecting rod 4 will bring all the clamping arms 5 together along the direction of the track groove 6 toward the center of the track disk 2 and clamp the object in the center. During this process, the bottom support plate 11 set at the bottom of the clamping arm 5 can play a supporting role at the bottom of the object to be transported. Its purpose is to prevent the object from shaking during transport, thereby ensuring better stability of the drone during flight.

[0036] After the transported object reaches its destination, the hydraulic cylinder 3 returns to its initial position. Driven by the connecting rod 4, all the clamping arms 5 are released simultaneously, and the bottom support plate 11 at the bottom of the clamping arms 5 is also pulled out from the bottom of the goods, thus realizing the unloading of the goods.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
