Description

Technical Field

[0001] This invention relates to the field of drone lifting technology, specifically a drone logistics lifting device. Background Technology

[0002] With the rapid development of drone technology, drones are increasingly widely used in logistics and delivery, playing a crucial role, especially in emergency supplies delivery and remote area distribution. However, existing drone delivery devices still present numerous problems in practical use. For example, during flight, due to airflow disturbances, drone maneuvers, or load inertia, the delivered goods are prone to violent shaking, causing the center of gravity to deviate from the drone's heading axis, severely affecting the drone's dynamic balance and flight stability. This instability not only increases the difficulty of operation but may also lead to safety accidents, especially under complex weather conditions. Furthermore, traditional delivery devices often have simple structures and lack effective buffering and stabilization mechanisms, failing to effectively suppress shaking. This can cause goods to easily shift or rotate during transportation, further increasing the drone's energy consumption and control burden. In the delivery stage, existing devices typically rely on simple release mechanisms, resulting in low delivery accuracy and inability to achieve precise and reliable release, especially when high-altitude or mobile delivery is required, which can easily lead to delivery failures or damage to the goods. At the same time, the disassembly and maintenance of existing devices are usually cumbersome, with low modularity, increasing usage costs and maintenance difficulty, thus limiting their large-scale application.

[0003] For example, the Chinese utility model patent (application number: CN202510871979.8) discloses "An Intelligent Emergency Drone Logistics Lifting and Deployment Device and Method," which states that intelligent emergency drones are playing an increasingly important role in modern emergency rescue. When ground transportation is disrupted, emergency drones can provide an efficient way to deliver supplies and are widely used in emergency transport and deployment of goods. They can carry relief supplies such as food, water, and first-aid medicines, and quickly deliver them to disaster areas to provide much-needed assistance to affected people. However, during the emergency lifting and deployment of goods, as well as during the retraction and deployment of the delivery line, emergency drones are prone to violent shaking of the goods due to airflow or inertia. This causes the center of gravity of the goods to deviate from the drone's heading axis, seriously affecting the dynamic balance of the drone and causing instability in the entire drone system, thus affecting the control of the drone and the delivery of goods.

[0004] Therefore, we have made improvements to this and proposed a drone logistics lifting and launching device. Summary of the Invention

[0011] As a preferred technical solution of this application, the outer side of the mounting bracket extends through the support assembly to its inner side, and the two ends of the mounting bracket are provided with snap-fit ​​grooves. The snap-fit ​​grooves are smaller at the top and larger at the bottom. The snap-fit ​​grooves match the support assembly. The support assembly includes mounting tubes symmetrically sleeved on both sides of the mounting bracket. The mounting tubes are inclined and the outer side of the mounting tubes is provided with side grooves. The mounting tubes are sleeved with the mounting bracket through the side grooves.

[0012] As a preferred technical solution of this application, a pad is fixedly installed on the inner side of the mounting tube. The top of the pad is higher than the bottom of the side groove. A connector is fixedly installed on the top of the pad. A torsion spring is rotatably sleeved on the outer side of the connector. A retaining tube is rotatably sleeved on the outer side of the connector through the torsion spring. The retaining tube is inclined and extends through the retaining groove to the inner side of the mounting frame.

[0013] As a preferred technical solution of this application, a first sleeve plate and a first pad tube are symmetrically arranged on the outer side of the mounting tube.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. By working together with symmetrically distributed support components and hoisting components, combined with buffer units arranged at multiple points on the outer side of the ring plate, consisting of the first telescopic rod, the first spring, and the first ball rod, a multi-directional spatial shock absorption structure is formed. This structure can efficiently absorb and disperse the multi-dimensional impact and vibration energy generated by airflow turbulence and maneuvering during flight, fundamentally suppressing the swaying and rotation of the logistics bag, ensuring the long-term stability of the load center of gravity, thereby greatly improving the flight stability, maneuverability, and safety of the UAV.

[0019] 2. The drive motor drives the connecting shaft via a plum blossom-shaped transmission shaft, which in turn drives the movable arc plate and the cutter to rotate precisely. The cutter is designed to run closely along the inner track of the hook, ensuring that it can quickly and thoroughly cut the loops of the logistics bag and complete the release. This mechanical cutting and release mechanism is decisive and less affected by environmental interference. It solves the problems of jamming, mis-release, or insufficient release accuracy that exist in traditional throwing methods, and is especially suitable for application scenarios with high requirements for release point accuracy.

[0020] 3. The closure of the fixed and movable arc plates during transportation provides an effective physical barrier for the hook area at the top of the ring plate, preventing the intrusion of debris. At the same time, the guide strip design on the outside of the fixed arc plate guides and straightens the airflow passing through the device, effectively reducing aerodynamic resistance and eddies that may induce vibration, thus optimizing aerodynamic performance and providing additional stability for the hoisting system.

[0021] 4. The device adopts a locking tube based on torsion spring reset and a locking groove with a smaller upper part and a larger lower part, which realizes automatic locking and self-strengthening of load during installation, as well as manual quick release during maintenance. This makes the disassembly, replacement and maintenance of the entire hoisting device extremely convenient. It not only realizes the non-destructive landing and quick replacement of logistics bags, but also significantly reduces the life cycle maintenance cost of the equipment.

[0022] 5. The support assembly integrates elastic elements such as a second telescopic rod and a second spring, and is combined with a ball joint structure. It can adaptively deform and buffer according to the load state and external excitation. This design effectively mitigates instantaneous impact loads under conditions such as take-off and landing and sudden winds, protects the structural integrity of the UAV body and the hoisting device, and thus improves the reliability and durability of the entire system.

[0036] 4. Logistics bags. Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] This invention provides a technical solution: such as Figure 1 - Figure 9 The drone logistics hoisting device shown includes a drone body 1, logistics bags 4 for holding materials are arranged at intervals below the drone body 1, a hoisting component 3 for suspending the logistics bags 4 is arranged on the top of the logistics bags 4, and support components 2 for connecting the drone body 1 and the hoisting component 3 are symmetrically arranged on the outside of the hoisting component 3.

[0039] like Figure 7 , Figure 8 and Figure 9As shown, the hoisting assembly 3 includes a ring plate 301 located below the UAV body 1. Hooks 302 are arrayed on the inner side of the ring plate 301 and match the logistics bag 4. The hooks 302 are tilted downwards. A fixed arc plate 303 is symmetrically installed on the inner side of the ring plate 301, and a guide strip 304 is fixedly installed on the outer side of the fixed arc plate 303. The fixed arc plate 303 is located above the hooks 302. The hooks 302 facilitate the hanging of the logistics bag 4. The bottom of the fixed arc plate 303 is combined with the hooks 302 to limit the logistics bag 4 when it is engaged, thereby preventing the logistics bag 4 from falling off due to shaking during movement.

[0040] Furthermore, the hoisting assembly 3 also includes a mounting cover 308 disposed below the UAV body 1, and the mounting cover 308 is located on top of the ring plate 301. A mounting bracket 306 is fixedly mounted on the outside of the mounting cover 308, and radial chains 305 are mounted in an array on the bottom of the outside of the mounting cover 308, with the other end of the chains 305 connected to the top of the ring plate 301.

[0041] Furthermore, a drive motor 309 is fixedly installed inside the mounting cover 308. A transmission shaft 310 is fixedly installed at the output end of the drive motor 309. The lower middle part of the transmission shaft 310 is shaped like a plum blossom. A connecting shaft 311 is snapped onto the outer side of the transmission shaft 310. A curved movable arc plate 312 is symmetrically installed at the bottom of the connecting shaft 311. A cutter 313 is fixedly installed on the bottom inner side of the movable arc plate 312. The movable arc plate 312 and the fixed arc plate 303 facilitate the protection of the top of the ring plate 301 during transportation, preventing impurities from entering the inner side of the ring plate 301 and affecting the logistics bag 4. The airflow guide strip 304 on the outer side of the fixed arc plate 303 can guide the airflow during transportation. The cutter 313 is inclined, with both ends of the movable arc plate 312 located inside the fixed arc plate 303. The inner side of the cutter 313 is close to the hook 302. Inside the device, the size of the cutter 313 is smaller than the distance between two adjacent sets of hooks 302. In the initial state, the cutter 313 is located between two sets of adjacent hooks 302 and engages with the hooks 302 through symmetrically arranged movable arc plates 312, thereby limiting and engaging the logistics bag 4 to prevent it from falling off during transportation. When in use, the drive motor 309 is started, and the transmission shaft 310 fixedly installed at its output end drives the connecting shaft 311 engaged on its outer side to rotate. Then, the movable arc plates 312 symmetrically installed at the bottom of the connecting shaft 311 rotate, thereby driving the cutter 313 to rotate. During the rotation, the inner side of the cutter 313 is in close contact with the inner side of the hook 302. When the cutter 313 rotates, it cuts the hanging ears of the logistics bag 4 hanging inside the hook 302 by being in close contact with the inner side of the hook 302, thereby enabling high-altitude logistics delivery.

[0042] Furthermore, the outer side of the mounting bracket 306 extends through the support assembly 2 to its inner side. The two ends of the mounting bracket 306 are provided with snap-fit ​​grooves 307, which are smaller at the top and larger at the bottom. The snap-fit ​​grooves 307 match the support assembly 2. The support assembly 2 includes mounting tubes 201 symmetrically sleeved on both sides of the mounting bracket 306. The mounting tubes 201 are inclined. The outer side of the mounting tubes 201 is provided with side grooves 217, and the mounting tubes 201 are sleeved with the mounting bracket 306 through the side grooves 217.

[0043] like Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a pad 218 is fixedly installed on the inner side of the mounting tube 201. The top of the pad 218 is higher than the bottom of the side groove 217. A connector 220 is fixedly installed on the top of the pad 218. A torsion spring 221 is rotatably sleeved on the outer side of the connector 220. A retaining tube 219 is rotatably sleeved on the outer side of the connector 220 through the torsion spring 221. The retaining tube 219 is inclined and extends through the retaining groove 307 to the inner side of the mounting frame 306. During use, the mounting frame 306 is retained by the side groove 217, and the retaining tube 219, in conjunction with the retaining groove 307, limits the mounting frame 306. When the drone body 1 lifts the support assembly 2, the hoisting assembly 3, and the logistics bag 4, the logistics bag 4 falls under its own weight, pulling the entire hoisting assembly 3 downward. At this time, the mounting frame 306 is... The side groove 217 slides downwards to limit the movement of the mounting bracket 306, and the snap-fit ​​grooves 307 at both ends of the mounting bracket 306 slide along the snap-fit ​​tube 219. At this time, the snap-fit ​​tube 219 is limited by the torsion spring 221 and the snap-fit ​​block 222, so that the mounting bracket 306 and the snap-fit ​​tube 219 are fully engaged, thereby reinforcing the entire hoisting assembly 3 and preventing the hoisting assembly 3 from falling off during transportation. During the deployment process, the UAV body 1 places the logistics bag 4 on the ground. At this time, the mounting bracket 306 is in the initial state. Then, the snap-fit ​​tube 219 is manually rotated outwards to disengage it from the snap-fit ​​groove 307 and rotate through the side groove 217 to the outside of the mounting tube 201. Then, the mounting bracket 306 is manually removed, and the hoisting assembly 3 is modularly replaced and repaired to reduce the cost of use. At the same time, the logistics bag 4 is removed without damage, thus realizing the landing and hoisting.

[0044] Furthermore, a first sleeve plate 202 and a first pad tube 203 are symmetrically arranged on the outer side of the mounting tube 201. The first sleeve plate 202 and the first pad tube 203 are connected by bolts 208. A second telescopic rod 215 is spherically sleeved on the inner side of the first pad tube 203. A second sleeve 214 is rotatably sleeved on the outer side of the second telescopic rod 215. A second spring 216 is fixedly installed at the end of the second telescopic rod 215 away from the first pad tube 203, and the other end of the second spring 216 is fixedly connected to the inner side of the second sleeve 214. The bottom of the second sleeve 214... The ring plate 301 is spherically connected to the top of the ring plate 301. During use, when the hoisting assembly 3 moves down under the action of gravity, the ring plate 301 will pull the second spring 216 along the second telescopic rod 215 through the second sleeve 214 connected to the top of the ring plate 301, thereby providing a sliding stroke for the mounting frame 306. It can also buffer the ring plate 301 during transportation, thereby reducing the impact of wind and impact on the entire hoisting assembly 3 during movement. Furthermore, the first sleeve 202 and the first pad tube 203 facilitate modular installation.

[0045] Furthermore, a sleeve groove 204 is provided through the end of the mounting tube 201 away from the UAV body 1. A support rod 205 is sleeved on the mounting tube 201 through the sleeve groove 204. The support rod 205 is perpendicular to the mounting tube 201. A second pad tube 206 is symmetrically arranged on the bottom of the outer side of the support rod 205 about the mounting tube 201. A second sleeve plate 207 is provided on the top of the second pad tube 206. The second pad tube 206 and the second sleeve plate 207 are fixedly connected by bolts 208. The second pad tube 206 and the second sleeve plate 207 facilitate modular connection, thereby facilitating replacement and maintenance and reducing costs.

[0046] Furthermore, a second cue stick 213 is fixedly installed on the top of the second sleeve plate 207. The top of the second cue stick 213 is spherically sleeved with a first sleeve 209. A first telescopic rod 210 is sleeved through the inside of the first sleeve 209. A first spring 212 is fixedly installed at one end of the first telescopic rod 210 located inside the first sleeve 209, and the other end of the first spring 212 is fixedly connected to the inside of the first sleeve 209.

[0047] Furthermore, the first telescopic rod 210 is spherically sleeved with the first ball rod 211 at one end outside the first sleeve 209, and the other end of the first ball rod 211 is fixedly connected to the outside of the ring plate 301. In use, the first telescopic rod 210, the first sleeve 209 and the first spring 212 installed in an array on the outside of the ring plate 301 provide all-round buffering for the ring plate 301 during transportation, thereby reducing the impact of airflow and impact on the hoisting assembly 3.

[0048] Working principle: First, the logistics bag 4, which is used to hold the logistics, is suspended from the top of the bag by the ear or similar structure on the hooks 302 arrayed on the inner side of the ring plate 301 in the lifting assembly 3. The downward tilt of the hooks 302 facilitates hanging and provides initial constraint. At this time, the fixed arc plate 303, which is symmetrically installed on the inner side of the ring plate 301, is located above the hooks 302. Its bottom and the hooks 302 together form a limiting space to lock the top of the logistics bag 4, effectively preventing accidental fall due to shaking during subsequent movement.

[0049] The hoisting assembly 3, with the logistics bag 4 suspended, is connected to the support assembly 2 via the mounting bracket 306 on the outside of its mounting cover 308. During connection, both ends of the mounting bracket 306 are inserted into the side grooves 217 on the outside of the mounting tube 201. During this process, the retaining tube 219, which is provided with a reset torque by the torsion spring 221, is squeezed and temporarily rotated by the mounting bracket 306. When the retaining groove 307 on the mounting bracket 306 moves to the position corresponding to the retaining tube 219, the retaining tube 219 quickly springs back under the action of the torsion spring 221 and passes through. The snap-fit ​​groove 307 extends to the inner side of the mounting bracket 306. Since the snap-fit ​​groove 307 is smaller at the top and larger at the bottom, and the snap-fit ​​tube 219 is inclined, this structure allows the mounting bracket 306 to slide slightly in the side groove 217 when the drone body 1 lifts the entire device and the weight of the logistics bag 4 pulls the hoisting component 3 downward relative to the support component 2. This causes the inclined surface of the snap-fit ​​groove 307 to wedge more tightly with the snap-fit ​​tube 219, thereby achieving automatic locking and reinforcement, greatly enhancing the reliability of the connection during transportation and preventing the hoisting component 3 from falling off.

[0050] Radial buffer: The combination of multiple first telescopic rods 210 and first sleeves 209 connected between the outer side of the ring plate 301 and the top of the support rod 205 is equipped with a first spring 212 and a spherical sleeve achieved by the first ball rod 211 and the second ball rod 213, which constitutes the main radial buffer and constraint structure; it can allow the ring plate 301 to make multi-directional elastic displacement within a certain range, and absorb energy through the first spring 212, effectively suppressing the swing of the logistics bag 4 in the horizontal plane;

[0051] Axial and multi-directional buffering: The second telescopic rod 215 and the second sleeve 214, which are connected between the top of the ring plate 301 and the mounting tube 201, are equipped with a second spring 216 inside, and are connected to the first pad tube 203 through a spherical sleeve. This mainly deals with vertical impacts and vibrations. When the ring plate 301 is subjected to downward pulling force or upward impact, the second spring 216 is compressed or stretched to provide buffering. At the same time, its spherical sleeve structure also allows the component to adapt to changes in a certain angle during the buffering process, achieving a multi-dimensional stabilizing effect.

[0052] Protection: During transportation, the movable arc plate 312 and the fixed arc plate 303 together shield the top area of ​​the ring plate 301 to prevent external impurities from entering and affecting the connection between the hook 302 and the logistics bag 4.

[0053] Deployment: When the drone arrives at the delivery point and needs to release the logistics bag 4, the drive motor 309 inside the mounting cover 308 is activated. The output end of the drive motor 309 drives the transmission shaft 310 to rotate. The transmission shaft 310 is engaged with the connecting shaft 311 through its lower part in a plum blossom shape, thereby driving the two movable arc plates 312 symmetrically mounted at the bottom of the connecting shaft 311 to rotate. The cutter 313 fixed to the bottom inner side of the movable arc plate 312 rotates synchronously. The inner side of the cutter 313 moves along the inner trajectory of the hook 302. Since the size of the cutter 313 is smaller than the distance between two adjacent sets of hooks 302, and it is initially located between the two sets of hooks 302, its rotational movement is not interfered with. During the rotation, the sharp cutter 313 cuts the lugs of the logistics bag 4 hanging on the hook 302, thereby realizing the detachment and deployment of the logistics bag 4. This mechanical cutting method is accurate and reliable, ensuring the success rate of high-altitude deployment.

[0054] After the logistics delivery is completed, or when maintenance is required, the hoisting component 3 can be removed from the support component 2. The specific operation is as follows: manually rotate the clamping pipe 219 outward to overcome the torque of the torsion spring 221 and completely rotate it out of the clamping groove 307 and the side groove 217, thus detaching it from the mounting frame 306. Then, the mounting frame 306 can be pulled out from the mounting pipe 201 along the side groove 217 to achieve quick separation of the hoisting component 3. Similarly, the various parts of the support component 2, such as the first sleeve plate 202 and the first pad pipe 203, and the second pad pipe 206 and the second sleeve plate 207, are all connected by bolts 208, which also facilitates partial replacement or maintenance.
