Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and more specifically, to a heavy-duty industrial UAV. Background Technology

[0002] Heavy-duty industrial drones are powerful aerial operations with robust payload capabilities, typically ranging from tens to hundreds of kilograms. Equipped with multi-axis power systems, high-efficiency motors, and large-capacity energy devices, they can stably perform long-duration, high-intensity tasks. In logistics transportation, they can quickly deliver heavy packages; in emergency rescue, they can transport supplies to mountainous and flood-stricken areas; and in agricultural operations, their high-capacity pesticide tanks enable large-area plant protection spraying. Their flight is stable, with precise positioning and obstacle avoidance capabilities. They are easy to operate, support intelligent planning and remote control, and can be customized to meet the needs of different industries, greatly improving operational efficiency in various fields and making them invaluable tools in the industrial sector.

[0003] Currently, most heavy-duty industrial drones use a fixed, integrated mounting structure. When handling cargo of varying sizes and weights, this requires replacing mounting components, which is cumbersome, time-consuming, and significantly reduces operational efficiency. Furthermore, repeated disassembly and reassembly can cause wear and tear on the fuselage connections, shortening the equipment's lifespan. Therefore, we propose a new heavy-duty industrial drone. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a heavy-duty industrial drone to solve the technical problem of needing to change the mounting components when transporting goods of different sizes and weights.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a heavy-duty industrial unmanned aerial vehicle (UAV), including a UAV body and a mounting mechanism disposed at the lower end of the UAV body. The mounting mechanism includes a first connecting plate, with a first mounting plate at both ends of the first connecting plate, and a first lead screw between the first mounting plates. The first lead screw is a bidirectional lead screw. A first crank handle connected to the axis of the first lead screw is rotatably mounted on the first mounting plate on the back side. A mounting plate is disposed on the bottom surface of the slider of the first lead screw. A landing rod is symmetrically disposed at the end of the mounting plate. A second connecting plate is disposed at the lower end of the first mounting plate on the back side. A second mounting plate is disposed on both ends of the second connecting plate, and a second lead screw is disposed between the second mounting plates. A second crank handle connected to the axis of the second lead screw is rotatably mounted on the second mounting plate. A fixing rod is disposed on the bottom surface of the slider of the second lead screw. A limit plate is disposed at the end of the fixing rod, and the limit plate is located on the outer side between the mounting plates.

[0006] Preferably, each of the two first mounting plates has a fixing plate at its upper end, the fixing plate being connected to the UAV body, and the front of the first mounting plate located on the front side is arranged in an inwardly curved arc shape.

[0007] Preferably, a limiting opening is provided in the extended axis direction of the first connecting plate, the lower part of the slider of the first lead screw is located in the limiting opening, and the size of the limiting opening is adapted to the size of the slider of the first lead screw.

[0008] Preferably, the mounting plate is curved in an arc shape along its long axis, the upper part of the mounting plate has air holes, and the lower end of the mounting plate has a horizontal support part.

[0009] Preferably, the landing rod includes, along its long axis, a bent portion, a downward-sloping portion, a first curved portion, and a second curved portion. The bent portion is L-shaped, and the downward-sloping portion is bent at ninety degrees at the end of the bent portion. The downward-sloping portion is inclined downwards.

[0010] Preferably, the first and second curved portions are curved in opposite directions to form an arc shape, the first and second curved portions form an S-shape, and damping rods are provided in both the first and second curved portions.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the design of a mounting plate structure, uses a bidirectional screw to adjust the mounting plate. Combined with a limiting plate, it allows for quick adaptation to goods of different sizes and weights without replacing any mounting components, improving operational efficiency. It also avoids wear and tear on the fuselage connections caused by repeated disassembly and assembly, extending the equipment's lifespan. Furthermore, the first mounting plate on the front adopts an inwardly curved arc design, and the mounting plate is also curved along its long axis. Air vents are also provided on the upper part of the mounting plate. These structural designs effectively reduce air resistance during drone flight, lowering the power system's energy consumption. This allows the drone to have longer flight time in heavy-load transportation scenarios, increasing the transportation range and efficiency of a single operation. It is particularly suitable for logistics transportation, emergency rescue, and other missions requiring long-duration flights, solving the current problem of needing to replace mounting components when transporting goods of different sizes and weights.

[0012] 2. This utility model also features a landing pole structure designed as an integrated unit with the mounting plate, allowing the drone to land without the need for a landing gear. The first and second curved sections of the landing pole are curved in opposite directions to form an S-shape and are made of highly elastic spring steel. During landing, the deformation absorbs the impact force from the ground. At the same time, the damping rod inside the curved section suppresses vibration and prevents the drone from swaying continuously after landing. The inclined design of the lower section guides the landing pole to make a smooth contact with the ground first, further improving landing stability and reducing the impact on the fuselage and cargo during landing, thus protecting the equipment and cargo.

Detailed Implementation

[0015] like Figures 1 to 5As shown, this utility model relates to a heavy-duty industrial unmanned aerial vehicle (UAV), including a UAV body 101 and a mounting mechanism 200 disposed at the lower end of the UAV body 101. The mounting mechanism 200 includes a first connecting plate 201, with a first mounting plate 202 disposed at both ends of the first connecting plate 201. A first lead screw 204 is disposed between the first mounting plates 202. The first lead screw 204 is a bidirectional lead screw. A first crank 205, which is rotatably mounted on the first mounting plate 202 on the back and is axially connected to the first lead screw 204, is mounted on the bottom surface of the slider of the first lead screw 204. A landing rod 212 is symmetrically arranged at the end of the plate 206. A second connecting plate 207 is arranged at the lower end of the first mounting plate 202 on the back. A second mounting plate 208 is arranged at both ends of the second connecting plate 207. A second lead screw 209 is arranged between the second mounting plates 208. A second crank 213, which is rotatably mounted on the second mounting plate 208 and is axially connected to the second lead screw 209, is mounted on the second mounting plate 208. A fixing rod 210 is arranged on the bottom surface of the slider of the second lead screw 209. A limit plate 211 is arranged at the end of the fixing rod 210. The limit plate 211 is located on the outer side between the mounting plates 206. This utility model adjusts the mounting plate 206 and the limit plate 211 by the lead screw to adapt to different cargoes, improve efficiency and reduce body wear. The arc-shaped mounting plate and the arc-shaped mounting plate 206 with air holes reduce wind resistance and save energy. The S-shaped elastic landing rod 212 with damping rod 2124 ensures a smooth landing and protects the equipment and cargo.

[0016] Specifically, each of the two first mounting plates 202 has a fixing plate 203 at its upper end. The fixing plate 203 is connected to the UAV body 101. The front of the first mounting plate 202 is curved inward. The fixing plate 203 is connected to the UAV body 101 by bolts or other connectors, achieving a stable assembly between the mounting mechanism 200 and the UAV body 101, preventing the mounting mechanism 200 from falling off during flight. The curved design of the front of the first mounting plate 202 reduces air resistance during flight, lowers the UAV's energy consumption, and enhances the overall aesthetics of the structure.

[0017] Furthermore, a limiting opening is provided on the first connecting plate 201 along its extended axis. The lower part of the slider of the first lead screw 204 is located within the limiting opening, and the size of the limiting opening is adapted to the size of the slider of the first lead screw 204. The limiting opening can restrict the movement trajectory of the slider of the first lead screw 204, prevent the slider from rotating, and ensure that it moves only along the axial direction.

[0018] It is worth noting that the mounting plate 206 is curved along its long axis, with air vents at the top and a horizontal support section 2061 at the bottom. The air vents reduce the force of airflow on the mounting plate 206 during flight, thus reducing wind resistance. Furthermore, the curved shape at the bottom of the mounting plate 206 reduces air resistance during flight, lowering the drone's energy consumption. After the cargo is secured, the support section 2061 supports the bottom of the cargo, preventing it from falling during transport.

[0019] It is worth noting that the landing stick 212 includes, along its long axis, a bent portion 2120, a downward-sloping portion 2121, a first curved portion 2122, and a second curved portion 2123. The bent portion 2120 is L-shaped, and the downward-sloping portion 2121 is bent at a 90-degree angle at the end of the bent portion 2120. The downward-sloping portion 2121 is inclined downwards, and this downward-sloping angle guides the landing stick 212 to contact the ground first, ensuring a smooth landing.

[0020] It is worth noting that the first curved portion 2122 and the second curved portion 2123 are curved in opposite directions to form an arc shape, thus forming an S-shape. Both the first curved portion 2122 and the second curved portion 2123 are equipped with damping rods 2124, and both are made of spring steel. The arc-shaped structure has good elasticity and can deform to absorb impact force during landing. The S-shaped design further enhances the buffering effect and extends the impact force transmission path. The damping rods 2124 in both the first curved portion 2122 and the second curved portion 2123 suppress vibration of the curved portion, preventing continuous swaying after landing and improving the landing stability of the UAV.

[0021] Working Principle: This embodiment provides a heavy-duty industrial drone. In use, the first step is to adjust the load according to the volume and weight of the cargo to be transported, ensuring the cargo is positioned between the mounting plates 206 and above the support section 2061. The operator can rotate the first crank 205 on the first mounting plate 202 on the back. Since the first lead screw 204 is a bidirectional lead screw, it will rotate synchronously with the rotation of the first crank 205. At this time, the two sliders on the first lead screw 204 will move in opposite directions along the axial direction of the first lead screw 204 under the constraint of the limiting opening in the first connecting plate 201 (preventing slider rotation and ensuring stable movement only along the axial direction). This, in turn, drives the two mounting plates 206 connected to the bottom surface of the sliders to move synchronously. Once the two mounting plates 206 contact the cargo, they can limit the cargo's movement forward and backward. Next, to fix the cargo longitudinally, the operator rotates the second crank 213 on the second mounting plate 208. The second lead screw 209 rotates with the second crank 213, and its slider moves axially, causing the limiting plate 211 at the end of the bottom fixing rod 210 of the slider to move. This allows the two limiting plates 211 to respectively adhere to the outer walls of both sides of the cargo (because the limiting plates 211 are located on the outer side between the mounting plates 206, they can accurately clamp and limit the cargo laterally), thus completing the cargo fixation. The entire adjustment process does not require replacing any mounting components, adapting to cargo of different volumes and solving the problems of cumbersome and time-consuming operation of traditional mounting structures. Once the cargo is secured, the drone body 101 is activated. During flight, the inwardly curved arc design of the first mounting plate 202, the arc-shaped structure along the long axis of the mounting plate 206, and the vents on the upper part of the mounting plate 206 all effectively reduce air resistance and lower the drone's flight energy consumption. Simultaneously, the first connecting plate 201 and the first mounting plate 202 are securely connected to the drone body 101 via a fixing plate 203 (e.g., bolted), ensuring a reliable connection between the mounting mechanism 200 and the drone body 101 and preventing the mounting mechanism 200 from detaching or swaying during flight, thus affecting the stability of cargo transport. When the drone reaches its destination and prepares to land, the landing stick 212 contacts the ground first, and its lower... The downward-sloping section 2121 guides the landing stick 212 to make a smooth landing. The impact force is then transmitted to the bending section 2120, and then sequentially to the first bending section 2122 and the second bending section 2123. Since the first bending section 2122 and the second bending section 2123 are bent in opposite directions to form an S-shape and are made of spring steel, they have good elasticity and will deform under the impact force to absorb part of the impact force. At the same time, the damping rods 2124 in the first bending section 2122 and the second bending section 2123 will suppress the vibration of the bending section, prevent the drone from shaking continuously after landing, and further improve the landing stability. After the drone has landed completely and smoothly, the cargo can be retrieved, and a transportation mission is completed.
