In fact, UAVs are a general term for unmanned aerial vehicles, which, from a technical perspective, can be divided into unmanned fixed-wing aircraft, unmanned vertical takeoff and landing aircraft, unmanned airships, unmanned helicopters, unmanned multi-rotor aircraft, and unmanned paragliders, among others.

[0003] The drone nest enables the recovery and sealed storage of medium-sized drones; however, the drone's propellers are designed to be foldable and retractable, which requires operators to manually fold all the propellers one by one, a process that is both tedious and reduces recovery efficiency. Utility Model Content

This device can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic drone nest closing and propeller collection device, comprising a collection box and an internal platform. The collection box is open, a positioning structure is installed on the top of the platform, a propeller collection structure is installed at the corners of the platform, and a lifting drive structure is connected to the center of the bottom of the platform. The propeller collection structure includes a push plate, a lever, and a rotating shaft.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The diagram illustrates an automatic drone nest closing and propeller collection device, comprising a collection box 1 and an internal platform 2. The collection box 1 is open. A positioning structure 4 is installed on the top of the platform 2, and propeller collection structures 3 are installed at the corners of the platform 2. A lifting drive structure 5 is connected to the center of the bottom of the platform 2. The propeller collection structure 3 includes a push plate 301, a lever 302, and a rotating shaft 304. Lever 302 is provided on the side walls of the platform 2 at each of the four corners, and two levers 302 are fixedly connected to each lever 302 on the platform 2. The clamping plate 305 has a rotating shaft 304. One end of the rotating shaft 304 passes through the inner clamping plate 305 and is fixedly connected to the rack plate 303. The other end of the rotating shaft 304 passes through the outer clamping plate 305 and is fixedly connected to the gear 307. A torsion spring 306 is arranged around one end of the rack plate 303. The bottom of the platform 2 has four rectangular push plates 301. Both ends of the push plates 301 are fixedly connected to the rack plates 303. Two levers 302 located at the corners of the platform 2 are stacked vertically.

[0022] It is worth noting that when the lifting drive structure 5 is started, it first pushes the four push plates 301 to move synchronously to the bottom center position of the platform 2, and then pushes the rack plate 303 to move horizontally. After moving a certain distance, this will cause it to mesh with the gear 307, and then push the rotating shaft 304 to rotate to a specific angle, so that the horizontally placed lever 302 moves in the vertical direction. The lever 302 contacts the drone propellers that are resting on the platform 2, thereby realizing the synchronous paddle movement and folding of the propellers. This process does not require manual sequential folding, and the synchronous folding of multiple propellers reduces time loss, saves operation time and reduces labor intensity, and realizes the automated folding and recycling of drone propellers.

[0023] Please see Figure 2 , Figure 4 and Figure 6 The positioning structure 4 includes positioning plates 401. Four rectangular positioning plates 401 are provided on the surface of the platform 2. Two positioning plates 401 on adjacent sides of the platform 2 are stacked vertically. It is worth noting that when the drone is on the surface of the platform 2 and its position is significantly deviated, the lifting drive structure 5 is activated, thereby driving the four positioning plates 401 to move synchronously towards the top center of the platform 2. The positioning plates 401 will contact the bottom of the drone. By squeezing the drone towards the center, the original position deviation is reduced, thereby providing assistance for the subsequent propeller movement process and ensuring that the propeller can be accurately positioned and folded.

[0024] See Figure 1 and Figure 2 The top two sides of the collection box 1 are equipped with cover plates 101, and the two sides of the collection box 1 are provided with several heat dissipation cavities 102, so that the top of the collection box 1 is sealed after recycling to prevent dust from falling in and accumulating. The heat dissipation cavities 102 are to ensure normal ventilation and heat dissipation inside, and to ensure the heat dissipation process of internal components.

[0025] See Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7The lifting drive structure 5 includes a multi-stage telescopic cylinder 501, a swing rod 506, and a slide rod 508. The slide rod 508 is located at the center of the bottom of the platform 2. The multi-stage telescopic cylinder 501 is installed at the center of the bottom inside the folding box 1. A slip ring 505 is slidably sleeved on the slide rod 508. A baffle 504 is fixedly connected to the bottom end of the slide rod 508. The top of the baffle 504 is fixedly connected to the connecting rod 5010, and the bottom is fixedly connected to the output end of the multi-stage telescopic cylinder 501. The platform 2 has four long sliding cavities 40 arranged in a cross shape. 2. The first U-shaped plate 503 is slidably connected inside the long sliding cavity 402. The slider 308 is fixedly connected to one side wall of the first U-shaped plate 503. The bottom of the other end of the slider 308 is fixedly connected to the push plate 301. The top of the first U-shaped plate 503 is fixedly connected to the positioning plate 401. The outer wall of the slip ring 505 is fixedly connected to four annularly arranged second U-shaped plates 509. One end of the rocker arm 506 is rotatably connected to the bottom of the first U-shaped plate 503 through a pin 507, and the other end is rotatably connected to the inside of the second U-shaped plate 509 through a pin 507.

[0026] It is worth noting that when the multi-stage telescopic cylinder 501 is activated, the slip ring 505 is first pulled to move vertically downwards, which in turn moves one end of the swing arm 506 downwards. The other end of the swing arm 506 pushes the first U-shaped plate 503 to move horizontally, thereby causing the positioning plate 401 to move first and position the drone. Simultaneously, the slider 308 moves horizontally, which in turn moves the push plate 301 horizontally. When the rack plate 303 meshes with the gear 307, the rotating shaft 304 rotates, causing the lever 302 to rotate. The torsion spring 306 then acts. When the rack plate 303 and gear 307 no longer mesh, the rotating shaft 304 returns to its original position. The slip ring 505 moves the baffle 504 area, thereby pushing the baffle 504 downwards. The entire platform 2 and the drone are moved into the folding box 1 for placement without manual operation. This makes operation convenient. Furthermore, the folding process, positioning process, and propeller folding process are all driven by a single multi-stage telescopic cylinder 501, eliminating the need for multiple drive components and reducing costs.

[0027] See Figure 4 The platform 2 has four rectangular telescopic rods 502 fixedly connected to its bottom. The bottom of the telescopic rods 502 is fixedly connected to the bottom of the retraction box 1. It is worth noting that the telescopic rods 502 have high stability during several vertical movements and are not prone to horizontal swaying, thus ensuring the stable retraction process of the UAV.

[0028] Please see Figure 5 and Figure 6The two adjacent push plates 301 have a difference in height in the vertical direction. The rack plate 303 located at the higher position engages with the gear 307 first. It is worth noting that the difference in height allows the coarse process to be stacked and stored without forming staggered collisions. The rack plate 303 located at the higher position engages with the gear 307 first, which allows the lever 302 located at the higher position to rotate first, preventing the levers 302 at the two corners from colliding during rotation and preventing interference.

[0029] Working principle: When the drone needs to be automatically closed and the propeller is collected, it is first placed on platform 2. At this time, if the position of the drone deviates significantly, the multi-stage telescopic cylinder 501 in the lifting drive structure 5 is activated. The output end of the multi-stage telescopic cylinder 501 will pull the baffle 504 and the slip ring 505 fixedly connected to it to move downward. The movement of the slip ring 505 is transmitted through the swing rod 506, which pushes the first U-shaped plate 503 to move horizontally in the long sliding cavity 402 on platform 2. The movement of the first U-shaped plate 503 not only drives the positioning plate 401 fixedly connected to it to move and position the drone, but also drives the push plate 301 to move horizontally synchronously through the slider 308.

[0030] As the push plate 301 moves, the rack plates 303 on both sides of it also move horizontally. When the rack plate 303 moves to the position of meshing with the gear 307, it will push the gear 307 to rotate, which in turn drives the rotating shaft 304 fixedly connected to it to rotate. The rotation of the rotating shaft 304 causes the lever 302, which was originally placed horizontally, to move vertically through the action of the torsion spring 306 and contact the propeller of the UAV, so as to realize the synchronous paddle movement and folding of the propeller. Since the four corners of the platform 2 are equipped with such propeller retraction structures 3, the synchronous folding of multiple propellers can be realized, reducing time loss and labor intensity.

[0031] During the process of the push plate 301 moving and pushing the rack plate 303 to mesh with the gear 307, since the push plates 301 at different positions have different heights in the vertical direction, the rack plate 303 at the higher position will mesh with the gear 307 first, causing the lever 302 at the higher position to rotate first. This can prevent the levers 302 at the two corner positions from colliding and interfering during rotation.

[0032] Once the drone is correctly positioned and the propellers are fully folded, the multi-stage telescopic cylinder 501 continues to pull the slip ring 505 downwards until the entire platform 2 and the drone placed on it are completely moved into the folding box 1.
