Description

Technical Field

[0001] This utility model belongs to the field of drone cargo technology, specifically relating to a drone cargo transportation device. Background Technology

[0002] As an emerging logistics tool, drones used for cargo transportation have seen rapid development in both military and civilian fields in recent years. Most cargo drones in use are small in size and mostly electrically powered, making them well-suited for frontline emergency transport missions and easy to use. When transporting goods, drones typically use clamping mechanisms to secure the cargo and prevent it from shaking or even falling off. For example, a drone for logistics distribution disclosed in the utility model patent with authorization announcement number CN112937860B uses a clamping mechanism to hold the items, which can effectively prevent the items from shaking when the drone is moving.

[0003] The existing technology has the following problems when in use: the clamping mechanism of the device creates a sliding groove in the transverse support plate. This sliding groove undermines the integrity of the transverse support plate, easily reduces its structural strength, and affects the stability of some goods on the transverse support plate. Utility Model Content

[0004] The purpose of this invention is to provide an unmanned aerial vehicle (UAV) cargo transportation device to solve the technical problems mentioned in the background above.

[0005] The specific technical solution adopted in this utility model is as follows:

[0031] Please see the appendix Figures 1 to 2 As shown, this utility model provides a drone cargo transportation device, including: a drone body 100, a limiting mechanism 300, and a leveling mechanism 400. A cargo transportation mechanism 200 is installed at the bottom of the drone body 100. The cargo transportation mechanism 200 includes a mounting plate 201, a connecting plate 202, and a support plate 203. The mounting plate 201 is fixedly installed at the bottom of the drone body 100. Symmetrical connecting plates 202 are fixedly installed on the bottom surface of the mounting plate 201. The support plate 203 is fixedly installed on the bottom surface of the connecting plate 202. When cargo is placed in the center of the top surface of the support plate 203 inside the cargo transportation mechanism 200, the drone body 100 can transport cargo by flying and driving the cargo transportation mechanism 200 to move.

[0032] In a preferred embodiment, please refer to Figures 1 to 3 A limit mechanism 300 is installed inside and at the bottom of the freight mechanism 200. The limit mechanism 300 consists of a first knob 301, a first threaded rod 302, a lifting block 303, a connecting rod 304, a first U-shaped plate 305, a second U-shaped plate 306, a first clamping plate 307, a second clamping plate 308, a rubber anti-slip pad 309, and a guide rod 310. The first knob 301 is located below the support plate 203. The first threaded rod 302 is fixedly installed on the top surface of the first knob 301. The lifting block 303 is installed through the outside of the first threaded rod 302. Four connecting rods 304 are hinged to the side of the lifting block 303. The other end of the connecting rod 304 is hinged with a symmetrical first U-shaped plate 305 and a symmetrical second U-shaped plate 306. A first clamping plate 307 is fixedly installed on the side of the first U-shaped plate 305 that is close to each other, and a second clamping plate 308 is fixedly installed on the side of the second U-shaped plate 306 that is close to each other. Rubber anti-slip pads 309 are fixedly installed on the side of the first clamping plate 307 and the second clamping plate 308 that are close to each other. A symmetrical guide rod 310 is fixedly installed on the bottom surface of the support plate 203. A through groove adapted to the guide rod 310 is provided through the top surface of the lifting block 303. The guide rod 310 passes through the through groove and slides through the lifting block 303.

[0033] In this embodiment, the guide rod 310 is used to guide the movement of the lifting block 303. The top of the first threaded rod 302 is rotatably connected to the support plate 203 through a bearing. The lifting block 303 is threadedly connected to the first threaded rod 302. The support plate 203 extends into the interior of the first U-shaped plate 305 and the second U-shaped plate 306. The upper and lower sides of the support plate 203 are slidably connected to the first U-shaped plate 305 and the upper and lower sides of the support plate 203 are slidably connected to the second U-shaped plate 306. The bottom surfaces of the first clamping plate 307 and the second clamping plate 308 are slidably connected to the top surface of the support plate 203.

[0034] In this embodiment, rotating the first knob 301 drives the first threaded rod 302 to rotate. The rotation of the first threaded rod 302 drives the lifting block 303 to move upward. The movement of the lifting block 303 drives the connecting rod 304 to rotate simultaneously. The rotation of the connecting rod 304 can drive the first clamping plate 307 and the second clamping plate 308 to move away from each other until the distance between the two first clamping plates 307 reaches its maximum. At this time, the distance between the two second clamping plates 308 also reaches its maximum. After placing the goods in the middle of the top surface of the support plate 203, rotating the first knob 301 in the opposite direction can drive the first clamping plate 307 and the second clamping plate 308 to move closer to each other until the first clamping plate 307 and the rubber anti-slip pad 309 clamp the goods, or the second clamping plate 308 and the rubber anti-slip pad 309 clamp the goods. At this time, the first knob 301 is stopped, and the goods are clamped and fixed. The limiting mechanism 300 has strong adaptability to different types and sizes of goods, avoids the goods from shaking relative to the support plate 203, and maintains the integrity of the support plate 203.

[0035] In a preferred embodiment, please refer to Figures 1 to 4 The drone body 100 has a leveling mechanism 400 at its bottom. The leveling mechanism 400 consists of a second knob 401 and a second threaded rod 402. Symmetrical second knobs 401 are provided below the two connecting plates 202. A second threaded rod 402 is fixedly provided on the top surface of the second knob 401. The second threaded rod 402 passes through the support plate 203 and is threadedly connected to the support plate 203. The second threaded rod 402 extends into the interior of the connecting plate 202 and is threadedly connected to the connecting plate 202.

[0036] In this embodiment, for goods with irregular shapes or uneven density, after the goods enter the cargo handling mechanism 200 and are fixed by the limiting mechanism 300, rotating the second knob 401 on the same side can drive the second knob 401 and the second threaded rod 402 on that side to move up and down, which can level the whole device, avoid one side being too heavy or too light, and improve the stability of the UAV body 100 during flight.

[0037] The working principle of this utility is as follows:

[0038] When using the device, rotating the first knob 301 drives the first threaded rod 302 to rotate. The rotation of the first threaded rod 302 causes the lifting block 303 to move upward. The movement of the lifting block 303 causes the connecting rod 304 to rotate simultaneously. The rotation of the connecting rod 304 can cause the first clamping plate 307 and the second clamping plate 308 to move away from each other until the distance between the two first clamping plates 307 reaches its maximum. At this time, the distance between the two second clamping plates 308 also reaches its maximum. The goods are placed in the center of the top surface of the support plate 203 inside the freight mechanism 200. Rotating the first knob 301 in the opposite direction can drive the first clamping plate 307 and the second clamping plate 308 to move away from each other. The clamping plates 308 are all close to each other until the first clamping plate 307 and the rubber anti-slip pad 309 clamp the goods, or the second clamping plate 308 and the rubber anti-slip pad 309 clamp the goods. Then the first knob 301 is stopped to clamp and fix the goods. The limiting mechanism 300 is highly adaptable to different types and sizes of goods, and prevents the goods from swaying relative to the support plate 203. Rotating the second knob 401 on the same side can move the second knob 401 and the second threaded rod 402 on that side up and down, which can level the whole device, avoid one side being too heavy or too light, and improve the flight stability of the UAV body 100.

[0039] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
