Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles, and in particular to an unmanned aerial vehicle carrying structure and an unmanned aerial vehicle. Background Art

[0002] When using drones to transport supplies, especially in special environments such as disaster areas where road access is relatively inconvenient, the traditional method of hanging supplies with ropes is inconvenient. For supplies such as medicines, first aid kits, and small communication equipment that require extremely high transportation stability, the rope hanging method is unreliable. Due to the characteristics of the rope itself, it is very easy to shake during the flight of the drone, resulting in unstable connection. When the drone faces complex flight conditions, such as frequent acceleration, deceleration or turning, the supplies suspended by the rope cannot be suspended stably, but will shake more and more violently, which will not only easily cause damage to the supplies, but also affect their normal use, and may even cause the supplies to fall off. Therefore, the present application provides a drone carrying structure and a drone to meet the needs. Summary of the invention

The inclined groove on the loading board can guide the materials to slide toward the middle, so that the center of gravity of the materials is closer to the center of the loading board, reducing the shaking caused by the center of gravity offset, making the placement of materials in the box more stable, and reducing the risk of materials being damaged by shaking during the flight of the drone; The gravity of the material itself can be used to trigger a series of mechanical structure actions, thereby achieving automatic clamping of the material, eliminating the need for an additional drive unit to clamp the material; The clamping rod can adaptively squeeze according to the shape of the material. When the clamping rod contacts the surface of the material, the extended end extends out and fits tightly against the outer wall of the material, providing a good clamping effect for materials of different shapes, enhancing the ability to fix the materials and ensuring that the materials will not shift easily during transportation.

DETAILED DESCRIPTION

[0029] The following is a detailed description of a drone carrying structure and a drone provided by the present invention in conjunction with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternative methods to implement some known technologies; and the accompanying drawings are only for a more specific description of the embodiments, and are not intended to specifically limit the present invention.

[0030] It should be noted that the references to "one embodiment", "embodiment", "exemplary embodiments", "some embodiments" and the like in the specification indicate that the embodiments described may include specific features, structures or characteristics, but not every embodiment may include the specific features, structures or characteristics. In addition, when a specific feature, structure or characteristic is described in conjunction with an embodiment, it should be within the knowledge of a person skilled in the art to implement such feature, structure or characteristic in conjunction with other embodiments (whether or not explicitly described).

[0031] In general, a term can be understood, at least in part, from its use in context. For example, depending, at least in part, on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in the singular sense, or can be used to describe a combination of features, structures, or characteristics in the plural sense. Additionally, the term "based on" can be understood as not necessarily intended to convey an exclusive set of factors, but can instead, depending, at least in part, on the context, allow for the presence of other factors that are not necessarily explicitly described.

[0032] like Figure 1-Figure 5 As shown, an embodiment of the present invention provides a UAV carrying structure, including a box 101 and a connecting portion 2 for hanging at the bottom of the UAV body 1, wherein the box 101 is used to store materials, and has a certain space and structural strength, can accommodate different types of materials, and provide preliminary protection for the materials. A box door 6 is rotatably installed on one side of the box 101, and when materials need to be placed or taken out, the box door 6 can be opened. An electronic lock is provided on the box door 6, and the electronic lock is communicated with the control system of the UAV. The operator can remotely control the opening and closing of the box door 6 through the control system, thereby improving the safety of material storage and the convenience of operation. The connecting portion 2 is used to connect to the bottom of the UAV body 1, and is a component for realizing the connection between the box 101 and the UAV body 1.

[0033] like Figure 1-Figure 4 As shown, the connecting part 2 includes a frame 201, which is connected to the bottom of the drone body 1 by bolts. A fixing part 202 is fixedly arranged on the inner wall of the frame 201, and a connecting part 203 is fixedly arranged on the outer side of the box 101. A wedge 204 is fixedly arranged on the side of the connecting part 203 close to the fixing part 202. The wedge 204 is made of elastic material. The wedge 204 made of elastic material can undergo a certain elastic deformation when squeezed, thereby absorbing and buffering a part of the vibration energy. The side where the fixing part 202 and the wedge 204 are close to each other is arranged in an inclined surface 205, and the fixing part 202 and the inclined surface 205 of the wedge 204 are squeezed and contacted with each other. This design of contact between the inclined surfaces 205 can increase the stability of the connection. When the drone is subjected to vibration or external force during flight, the squeezing between the inclined surfaces 205 can make the connection between the wedge 204 and the fixing part 202 tighter, thereby preventing relative displacement between the box 101 and the connecting part 2.

[0034] like Figure 1-Figure 7As shown, a slide groove 206 is provided on one side of the frame 201 close to the connecting member 203, and the connecting member 203 can be slidably connected to the inner wall of the frame 201 through the slide groove 206. A replaceable buffer part 4 is also installed on the frame 201 for buffering and shock absorbing the connecting part 2. The buffer part 4 includes a mounting groove 401 provided on the inner wall of the frame 201, and a sliding member 402 is slidably provided on the inner wall of the mounting groove 401. A fifth spring 403 is fixedly connected to the inner wall of the sliding member 402, and a spring piece 404 is fixedly connected to one end of the fifth spring 403. The spring piece 404 is made of a highly elastic and high-strength alloy material, and a buffer pad is provided on the side of the spring piece 404 that contacts the wedge 204. The buffer pad is made of elastic materials such as rubber or silicone to further improve the buffering effect. Part 4 has a buffering and shock-absorbing effect on the connecting part 2. The spring piece 404 is in contact with the wedge piece 204. When the UAV encounters vibration or impact during flight, the wedge piece 204 will transmit the vibration to the spring piece 404. The spring piece 404 will undergo elastic deformation when vibrated, and at the same time drive the fifth spring 403 to compress or extend. The elastic deformation of the fifth spring 403 can absorb and buffer the vibration energy, and reduce the impact of the vibration on the connecting part 2 and the box body 101. In addition, one side of the sliding part 402 is fastened to the surface of the frame 201 by bolts. This connection method makes the buffer part 4 easy to replace and maintain. When the components of the buffer part 4 are damaged or the performance is degraded, the new buffer part 4 components can be easily disassembled and replaced to ensure the buffering and shock-absorbing performance of the UAV carrying structure.

[0035] When it is necessary to transport materials by drone, the materials are placed in the box 101. The weight of the materials will cause the box 101 to drive the wedge 204 on the connecting member 203, so that it is closely pressed and contacted with the inclined surface 205 of the fixing member 202. In this process, the wedge 204 is pressed against the inclined surface 205 of the fixing member 202 along the inner wall of the frame 201, thereby achieving a stable connection between the box 101 and the connecting portion 2. When the drone accelerates, dives or turns during flight, the state of the materials in the box 101 will change accordingly. Due to these flight actions, the materials will slide slightly in the box 101. At this time, because the wedge 204 on the connecting member 203 always maintains a squeeze contact with the fixing member 202, the box 101 will drive the connecting member 203 to slide downward along the inclined surface 205 of the fixing member 202 on the inner wall of the frame 201, thereby causing the wedge 204 to be further squeezed downward along the inner wall of the frame 201 and the inclined surface 205 of the fixing member 202. When the wedge 204 slides downward along the inner wall of the frame 201 and the inclined surface 205 of the fixing member 202, the bottom of the wedge 204 will contact the spring 404, and the spring 404 will compress the fifth spring 403 after being squeezed. When the drone completes actions such as acceleration, diving or turning, the sliding of the materials also ends. At this time, the fifth spring 403 will restore its deformation, pushing the spring sheet 404 to push the wedge 204 away, so that it returns to the connection position when the materials are just put into the box 101. In this way, the spring sheet 404 and the fifth spring 403 cooperate with each other, which can not only effectively reduce the impact of vibration on the box 101 and the materials, play a good buffering role, but also ensure the stability of the connection structure; When it is necessary to replace a new spring 404, it is only necessary to loosen the bolts on one side of the frame 201, pull the sliding part 402 out from the installation position, replace the damaged spring and spring 404, and then install the new spring and spring 404 back into the sliding part 402. After such maintenance operations, the extrusion connection between the wedge 204 and the fixing part 202 can be made more secure. In this way, when the drone accelerates, dives or turns during flight, the connection strength between the box 101 driven by the connecting part 203 and the drone is significantly enhanced, effectively ensuring the safety and stability during the transportation of materials.

[0036] like Figure 1-Figure 13 As shown, a clamping portion 3 for clamping materials is installed on the inner wall of the box 101, and the clamping portion 3 includes a support plate 301, which is fixed to the inner wall of the box 101 to provide a stable support foundation for the entire clamping portion 3. A sliding groove 302 is provided on the surface of the support plate 301, and a loading plate 303 can slide on the inner wall of the sliding groove 302. The surface of the loading plate 303 is equidistantly provided with anti-slip grooves to increase the friction between the materials and the loading plate 303. An inclined groove 5 is provided on the surface of the loading plate 303, and the inclined groove 5 is inclined from both sides of the loading plate 303 to the middle, and the inclination direction shows a trend of gradually converging from both sides to the middle of the loading plate 303. The design of this inclined groove 5 plays an important role. When materials are placed on the loading plate 303, the inclined groove 5 can guide the materials to concentrate in the middle of the loading plate 303, so that the center of gravity of the materials is more stable and the sliding of materials caused by changes in flight posture is reduced.

[0037] like Figure 1-Figure 13 As shown, a first spring 304 is fixedly connected to the bottom of the loading plate 303, and one end of the first spring 304 is fixed to the inner wall of the sliding groove 302. When materials are placed on the loading plate 303, the loading plate 303 will press down the first spring 304 due to the weight of the materials. The first spring 304 is compressed to generate an elastic force. This elastic force can not only buffer the impact force on the loading plate 303 when the materials are placed, but also can adaptively adjust the position of the loading plate 303 according to the weight and shaking of the materials during the flight of the UAV to keep the materials relatively stable.

[0038] like Figure 1-Figure 13As shown, a rotating bar 305 is rotatably provided on the inner wall of the box body 101, and a side of the rotating bar 305 close to the loading plate 303 contacts the bottom of the loading plate 303. When the loading plate 303 moves up and down under the action of the material, the rotating bar 305 is driven to rotate around its rotation axis. A fixed sleeve 306 is also fixedly provided on the inner wall of the box body 101, and two sliding bars 307 are slidably provided on the inner wall of the fixed sleeve 306, wherein the length of one sliding bar 307 is longer than the other sliding bar 307, and the two sliding bars 307 are 7 are slidably connected to the inner wall of the box body 101, and an arc groove 308 is opened on the side of the sliding bar 307 close to the rotating bar 305. A push rod 309 is fixed on the rotating bar 305. The push rod 309 and the inner wall of the arc groove 308 are squeezed and contacted with each other. When the rotating bar 305 rotates, the push rod 309 will slide in the arc groove 308, thereby pushing the sliding bar 307 to slide in the fixed sleeve 306, and the up and down movement of the loading plate 303 can be converted into the horizontal sliding of the sliding bar 307, realizing the transmission and conversion of force.

[0039] like Figure 1-Figure 13 As shown, the inner wall of the fixed sleeve 306 is slidably provided with a first sliding plate 310, and a second spring 311 is fixed to the side of the first sliding plate 310 close to the sliding bar 307, and one end of the second spring 311 is fixedly connected to the sliding bar 307. When the sliding bar 307 slides under the push of the push rod 309, the second spring 311 is compressed or stretched. The elastic action of the second spring 311 can buffer the movement of the sliding bar 307 and prevent the sliding bar 307 from sliding violently due to sudden force. At the same time, after the movement of the sliding bar 307 is completed, it can also restore it to its initial position.

[0040] like Figure 1-Figure 13 As shown, a clamping box 312 is slidably provided on the surface of the carrier plate 303, a third spring 313 is fixedly connected to the bottom of the clamping box 312, a slider 314 is fixedly connected to the bottom end of the third spring 313, the slider 314 slides on the surface of the carrier plate 303, when the clamping box 312 is subjected to external force, it will slide on the surface of the carrier plate 303 through the slider 314 and compress or stretch the third spring 313, the function of the third spring 313 is to provide a certain buffer and elastic support for the clamping box 312, so that it can better adapt to the shape and size changes of materials.

[0041] like Figure 1-Figure 13As shown, the inner wall of the clamping box 312 is slidably provided with a second sliding plate 315, one side of the second sliding plate 315 is fixedly connected to a fourth spring 316, one end of the fourth spring 316 is fixed to the inner wall of the clamping box 312, and a plurality of clamping rods 317 are slidably provided on the side of the inner wall of the clamping box 312 away from the fourth spring 316, and a plurality of balls 318 are slidably placed on the inner wall of the clamping box 312 between the clamping rod 317 and the second sliding plate 315, and the side of the clamping rod 317 close to the ball 318 is in contact with the ball 318, and the end of the clamping rod 317 close to the material is wrapped with a flexible anti-skid layer, and the flexible anti-skid layer is made of sponge or soft rubber material The design of the ball bearing 318 can reduce the friction between the clamping rod 317 and the second sliding plate 315, making the sliding of the clamping rod 317 smoother. The side of the clamping box 312 close to the first sliding plate 310 is rotatably connected by the first connecting rod 319, and the two clamping boxes 312 are rotatably connected by the second connecting rod 320.

[0042] When materials are put into the box 101, the materials are placed on the loading plate 303 on the support plate 301. Since the loading plate 303 is provided with inclined grooves 5 on its surface and the inclined grooves 5 are inclined from both sides to the middle of the loading plate 303, the materials will slide along the inclined grooves 5 to the middle of the loading plate 303. On the one hand, the center of gravity of the materials is closer to the center of the loading plate 303, thereby improving the stability of material placement and reducing the shaking caused by the center of gravity offset; on the other hand, it is conducive to the subsequent clamping box 312 to accurately clamp the materials, making the clamping process more efficient and stable. At the same time, when the materials are placed on the loading plate 303, the weight of the materials will press the loading plate 303 to slide downward along the inner wall of the sliding groove 302. During the sliding process of the loading plate 303, the first spring 304 is compressed to provide a buffering effect for the loading plate 303. As the loading plate 303 descends, its bottom will contact the rotating bar 305 and push the rotating bar 305 to rotate in the counterclockwise direction. When the rotating bar 305 rotates, the push rod 309 fixed thereon will slide along the inner wall of the arc groove 308 on the sliding bar 307. In this process, the push rod 309 continuously squeezes the inner wall of the arc groove 308, thereby pushing the two sliding bars 307 to slide toward the side where the materials are located. The longer sliding bar 307 will continuously push the first sliding plate 310 to slide along the inner wall of the fixed sleeve 306 during the sliding process. When the first sliding plate 310 slides, the second spring 311 will be compressed, thereby driving the first sliding plate 310 to move forward. When the clamping box 312 on the first sliding plate 310 contacts the outer side of the material, the rotation of the rotating bar 305 continues to push the sliding bar 307 to slide, so that the clamping rod 317 on the clamping box 312 can contact the material. The clamping rod 317 will perform adaptive extrusion according to the shape of the material. When the clamping rod 317 contacts the surface of the material, its protruding end will extend out and fit tightly with the outer wall of the material to achieve preliminary clamping of the material. Since one sliding bar 307 is longer than the other sliding bar 307, after the longer sliding bar 307 pushes the clamping box 312 to contact the outer wall of the material, the shorter sliding bar 307 continues to slide forward, and the longer sliding bar 307 continues to push the first sliding plate 310, so that the second spring 311 continuously applies thrust, prompting the clamping box 312 to further clamp the material. When one of the clamping boxes 312 contacts and squeezes the outer wall of the material, the other clamping box 312 will squeeze and clamp the outer edge of the material through the rotation of the first connecting rod 319 and the second connecting rod 320. In this way, no matter what the shape of the material is, the clamping structure can achieve effective clamping of different materials through the synergistic effect of the two clamping boxes 312, greatly improving the versatility and practicality of the clamping part 3.

[0043] like Figure 1-Figure 4 As shown, the present invention also discloses a drone, which uses the above-mentioned drone carrying structure, including a drone body 1, and the drone body 1 is equidistantly installed with blades 7 on the outside to provide power for flight. A camera 8 for environmental observation is installed on one side of the drone body 1, which can provide real-time feedback of the surrounding situation. The bottom of the drone body 1 is symmetrically fixed with landing gears 9 to ensure smooth take-off and landing. The bottom of the drone body 1 is provided with a plurality of connecting bases 10 between the landing gears 9, and the top of the frame 201 is fixed thereto by bolts.

In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details.

These improvements and modifications should also be regarded as the scope of protection of the present invention.
