Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) technology, and more particularly to a take-off and landing assistance device for a maritime UAV. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and their own program control devices. When they are at sea, they are usually used for search and rescue operations.

[0003] In the prior art, such as Chinese Publication No. CN111924057B, this invention relates to the field of maritime unmanned aerial vehicle (UAV) take-off and landing technology, specifically a take-off and landing assistance device for a maritime UAV. A parking platform is provided above the control box, and a shock-absorbing mechanism connected to a maritime platform is provided at the bottom of the control box. An LED strip electrically connected to a microcomputer controller is embedded at the edge of the upper surface of the parking platform, and the UAV is parked on top of the parking platform. Two clamping mechanisms for fixing the UAV's landing gear are embedded in the upper surface of the parking platform. This invention is novel in design, simple in principle, and easy to operate. The clamping mechanisms can clamp the UAV's landing gear, ensuring its stability and preventing the UAV from being overturned and damaged by strong sea winds, thus improving rescue efficiency and reducing maintenance costs. The shock-absorbing mechanisms can provide shock absorption, ensuring stability during take-off and landing and reducing the difficulty of operation.

[0004] To prevent damage to drones from the forces generated during takeoff and landing, landing aids are used to cushion the impact. However, the cushioning effect is not very good, and damage to the drone is still possible. Securing the drone to the landing aid sometimes requires screws, which is inconvenient. Furthermore, when drones use monitoring devices to observe the sea surface and locate stranded personnel, they need to adjust their angles to adjust the angle of the monitoring devices. Adjusting the drone's angle requires changing its flight direction, making it susceptible to being blown off course by sea winds. Summary of the Invention

This invention provides a buffering effect when the UAV lands, protecting it and providing a good buffering effect. When fixing the UAV to the landing assistance device, the method is simple and convenient to use. There is no need to control the flight angle of the UAV.

[0021] As a further improvement of the present invention: a plurality of first positioning rods are fixedly connected to the top of the base, and a second positioning rod is movably sleeved on the other end of each of the plurality of first positioning rods, and an organic body is provided on the other end of the plurality of second positioning rods.

[0022] As a further improvement of the present invention: a square plate is provided on one side of the body, and two limiting holes are provided on both sides of the square plate.

[0023] As a further improvement of the present invention: a square plate is fixedly connected to one side of the mounting bracket, a guide rod is fixedly connected to one side of the square plate via a bearing, and a transmission frame is fixedly connected to the top of the guide rod.

[0026] As a further improvement of the present invention: the transmission frame is threadedly connected to the outer surfaces of the two clamping members.

[0027] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0028] 1. In this invention, when the drone descends, the two grounding rods first contact the ground. The base, through two first support rods and two second support rods, applies pressure to the two grounding rods respectively. When they reach a certain position, two stops prevent the rotation of the two first support rods. The two grounding rods then push two first elastic elements, which, under the compression of the two grounding rods, generate elastic force, thus producing a counterforce. This counterforce, at the moment the drone contacts the ground, has a buffering effect, protecting the drone. When the two first support rods reach a certain position, the pressure-bearing components will... Upon contact with the ground, the two ends of the two rotating rods rotate about two first horizontal axes and two second horizontal axes respectively. The two sliding cylinders can slide on the outer surface of the long rods. Thus, the pressure-bearing components are subjected to the impact force of the ground. Through the connecting parts, the two rotating rods push the two sliding cylinders respectively, which in turn begin to compress the two second elastic elements. The two second elastic elements generate elastic force under the compression of the two sliding cylinders, and also generate a reverse force, thereby achieving a buffering effect and protecting the drone. In this way, the elastic force generated by the compression of the two first elastic elements and the two second elastic elements provides a buffering effect at the moment of drone landing, protecting the drone, and the buffering effect is good.

[0029] 2. When fixing the drone to the landing assist device, the present invention uses multiple second positioning rods inserted into the outer surfaces of multiple first positioning rods to position the drone on the landing device. At this time, the square plate is on the outer surface of the container. The external power supply of the first motor is turned on, and the two L-shaped rods support the first motor, allowing the first motor to be mounted on the container. The output shaft of the first motor drives the threaded rod to rotate. The threaded rod can rotate through the two bearings. The threads inside the two sleeves are opposite. When the threaded rod rotates in different directions, the two sleeves move relative to or in opposite directions on the outer surface of the threaded rod. This causes the two insert rods on the two sleeves to move through the two sleeves. The two sliding grooves allow multiple moving rods to move, and the multiple insert rods are inserted into the limiting holes on the square plate, thereby fixing the drone. The method is simple and convenient to use.

[0030] 3. The two clamping components of this invention can move on both sides of the transmission frame. The two handles facilitate the movement of the two clamping components, thereby allowing the two pressure plates to fix the monitor. When clamping and fixing the monitor, the two protective components can be foam boards or gaskets, which are not limited here. The two protective components have a protective function to prevent the monitor from being deformed due to long-term compression. When it is necessary to adjust the angle of the monitor, turn on the external power supply of the second motor, so that the output shaft of the second motor rotates, which in turn rotates the straight gear through the bevel gear, thereby changing the angle of the transmission frame. Thus, it is not necessary to control the flight angle of the drone; only the rotation of the output shaft of the second motor needs to be controlled, avoiding excessive adjustment of the drone's flight angle, which could cause it to be blown down by the sea breeze.

[0043] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0044] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0045] Please see Figure 1-11This embodiment provides a landing assistance device for a marine unmanned aerial vehicle (UAV), including a base 1, two protrusions 208 fixedly connected to both sides of the base 1, with a third horizontal shaft 215 fixedly connected to the inner wall of each protrusion 208, two stops 209 fixedly connected to one side of each protrusion 208, two first support rods 2 movably sleeved on the outer surface of each of the two third horizontal shafts 215, with a second support rod 203 movably embedded at the other end of each of the two first support rods 2, two grounding rods 204 fixedly connected to the other end of each of the two second support rods 203, and two circular plates 201 respectively disposed on the side of each of the two first support rods 2 near the two grounding rods 204. Each side is provided with a first elastic element 202 and a long rod 210, which are located on the side of the base 1 near the two first support rods 2. The outer surfaces of the two long rods 210 are movably fitted with two sliding cylinders 212. Two second elastic elements 211 are respectively located on the side of the long rods 210 near the two sliding cylinders 212. Two second horizontal shafts 214 are respectively fixedly connected to the side of the two sliding cylinders 212 near the long rods 210. The outer surfaces of the two second horizontal shafts 214 are movably fitted with rotating rods 207. Two first horizontal shafts 213 are respectively fixedly connected to the other end of the two stops 209. The two ends of the two first horizontal shafts 213 are fixedly connected with connecting parts 206. A pressure bearing part 205 is located at the bottom of the connecting part 206.

[0046] As the drone descends, the two grounding rods 204 first contact the ground. The two first support rods 2 can rotate about the two third horizontal axes 215. When the two grounding rods 204 contact the ground, the base 1 applies pressure to the two grounding rods 204 through the two first support rods 2 and the two second support rods 203, causing the two first support rods 2 to rotate. When they reach a certain position, the two stops 209 will block the rotation of the two first support rods 2. The second support rods 203 can slide inside the two first support rods 2. At this time, the two... The grounding rod 204 pushes the two second support rods 203 into the interior of the two first support rods 2. One side of each of the two first elastic elements 202 is located on one side of each of the two circular plates 201. When the two grounding rods 204 reach a certain position, they push the two first elastic elements 202 respectively. The two first elastic elements 202 can be springs or buffer pads; there are no restrictions here. The two first elastic elements 202 are compressed by the two grounding rods 204, generating elastic force, which in turn generates a counterforce. This counterforce is applied to the ground where the drone contacts. The force generated at the moment of impact has a damping effect, thus achieving a buffering effect and protecting the drone. When the two first support rods 2 reach a certain position, the pressure-bearing component 205 will contact the ground after the two grounding rods 204 contact the ground. The two ends of the two rotating rods 207 rotate about the two first horizontal axes 213 and the two second horizontal axes 214 respectively. The two sliding cylinders 212 can slide on the outer surface of the long rod 210. Thus, the pressure-bearing component 205 is subjected to the impact force of the ground. Through the connecting piece 206, the two rotating rods 207 push the two... The slide cylinder 212 then begins to compress the two second elastic elements 211. The two second elastic elements 211 can be springs or metal sheets, which is not limited here. The two second elastic elements 211 generate elastic force under the compression of the two slide cylinders 212, and also generate a reverse force, thereby achieving a buffering effect and protecting the drone. Thus, the elastic force generated by the compression of the two first elastic elements 202 and the two second elastic elements 211 provides a buffering effect at the moment of landing of the drone, protecting the drone, and the buffering effect is good.

[0047] In one embodiment, a slot is provided at the bottom of the base 1, through which the circular plate 201 is installed at the bottom of the base 1, thereby achieving a cushioning effect.

[0048] Please see Figure 1-11In one embodiment, a trough box 303 is provided on the side of the base 1 near the long rod 210. Two L-shaped rods 309 are fixedly connected to one side of the trough box 303. A first motor 306 is installed at the other end of the two L-shaped rods 309. A threaded rod 304 is fixedly connected to the output shaft of the first motor 306. The two L-shaped rods 309 support the first motor 306, so that the first motor 306 is mounted on the trough box 303. When the external power supply of the first motor 306 is turned on, the output shaft of the first motor 306 drives the threaded rod 304 to rotate.

[0049] In another embodiment, the two ends of the threaded rod 304 are connected to the inner wall of the hopper 303 via bearings. The outer surface of the threaded rod 304 is threaded with sleeves 308. Movable rods 307 are fixedly connected to both sides of the two sleeves 308. Insert rods 305 are fixedly connected to the other ends of the multiple movable rods 307. The two sides of the hopper 303 are provided with sliding grooves that match the two movable rods 307. The threaded rod 304 can rotate through the two bearings. The threads inside the two sleeves 308 are opposite. When the threaded rod 304 rotates in different directions, the two sleeves 308 move relative to or in opposite directions on the outer surface of the threaded rod 304, thereby causing the two insert rods 305 on the two sleeves 308 to move through the two sleeves 308. The two sliding grooves cause the multiple movable rods 307 to move.

[0050] Please see Figure 1-11 In one embodiment, a plurality of first positioning rods 301 are fixedly connected to the top of the base 1. The other end of each of the plurality of first positioning rods 301 is movably fitted with a second positioning rod 302. The other end of each of the plurality of second positioning rods 302 is provided with an organism 5. When the drone lands, the plurality of second positioning rods 302 are inserted into the outer surface of the plurality of first positioning rods 301 respectively, thereby fixing the organism 5 on the landing device to achieve the fixation of the drone.

[0051] In another embodiment, a mounting bracket 3 is provided on one side of the body 5. Two limiting holes are provided on both sides of the mounting bracket 3. When the UAV is installed on the landing assistance device, the square plate 4 is on the outer surface of the trough box 303, so that multiple insert rods 305 are inserted into the limiting holes on the square plate 4 respectively, thereby fixing the UAV. The method is simple and convenient to use.

[0052] Please see Figure 1-11 In one embodiment, a square plate 4 is fixedly connected to one side of the mounting bracket 3, and a guide rod 401 is fixedly connected to one side of the square plate 4 via a bearing. A transmission frame 403 is fixedly connected to the top of the guide rod 401. The guide rod 401 can rotate on one side of the square plate 4, and the transmission frame 403 can fix the monitoring structure.

[0053] Please see Figure 1-11In one embodiment, clamping members 404 are provided on both sides of the transmission frame 403. A ruler gear 402 is provided on the side of the guide rod 401 near the transmission frame 403. A handle 405 is fixedly connected to one side of each clamping member 404. A pressure plate 411 is fixedly connected to the other side of each clamping member 404. A protective member 410 is provided on one side of each pressure plate 411. A monitor 406 is movably connected to one side of each protective member 410. The two clamping members 404 can move on both sides of the transmission frame 403. The two handles 405 facilitate the movement of the two clamping members 404, thereby allowing the two pressure plates 411 to fix the monitor 406. When clamping and fixing the monitor 406, the two protective members 410 can be foam boards or gaskets, which are not limited here. The two protective members 410 have a protective function to prevent the monitor 406 from being deformed due to long-term compression.

[0054] Please see Figure 1-11 In one embodiment, a second motor 407 is installed on the side of the square plate 4 near the monitor 406. The output shaft of the second motor 407 is fixedly connected to an adjusting rod 408. A bevel gear 409 is provided on the side of the adjusting rod 408 near the ruler gear 402. The outer surface of the bevel gear 409 meshes with the outer surface of the ruler gear 402. When it is necessary to control the monitor 406 to rotate, the external power supply of the second motor 407 is turned on, thereby causing the output shaft of the second motor 407 to rotate. This, in turn, causes the ruler gear 402 to rotate through the bevel gear 409, thereby changing the angle of the transmission frame 403. Thus, when it is necessary to adjust the angle of the monitor 406, it is not necessary to control the flight angle of the drone; simply controlling the rotation of the output shaft of the second motor 407 is sufficient. This avoids excessive adjustment of the drone's flight angle, which could lead to it being blown down by the sea breeze.

[0055] In one embodiment, the transmission frame 403 is threadedly connected to the outer surfaces of the two clamping members 404. By rotating the two clamping members 404 through the two handles 405, the two pressure plates 411 are moved, thereby clamping and fixing the monitor 406. Furthermore, the two protective members 410 fix the monitor 406 inside the transmission frame 403. When it is necessary to remove the monitor 406, the two clamping members 404 are rotated in the opposite direction through the two handles 405, thereby removing the monitor 406.

[0056] In another embodiment, the transmission frame 403 is telescopically connected to the outer surfaces of the two clamping members 404. By using two handles 405, the two clamping members 404 are pushed respectively, causing the two pressure plates 411 to move. Thus, the two pressure plates 411 clamp and fix the monitor 406, and further, the two protective members 410 fix the monitor 406 inside the transmission frame 403. When it is necessary to remove the monitor 406, the two clamping members 404 are pushed in the opposite direction by the two handles 405, thereby removing the monitor 406.

[0057] Working principle: When the drone descends, the two grounding rods 204 first contact the ground. The two first support rods 2 can rotate around the two third horizontal axes 215. When the two grounding rods 204 contact the ground, the base 1 applies pressure to the two grounding rods 204 through the two first support rods 2 and the two second support rods 203, thereby causing the two first support rods 2 to rotate. When they reach a certain position, the two stops 209 will block the rotation of the two first support rods 2. The second support rods 203 can slide inside the two first support rods 2. At this time, the two grounding rods 204 will push the two second support rods 203 into the interior of the two first support rods 2. One side of the two first elastic elements 202 is respectively located on the two circular plates. On one side of 201, when the two grounding rods 204 reach a certain position, they push the two first elastic elements 202 respectively. The two first elastic elements 202 are squeezed by the two grounding rods 204, generating elastic force, which in turn generates a reverse force. This reverse force has a damping effect on the force generated when the drone touches the ground, thus achieving a buffering effect and protecting the drone. When the two first support rods 2 reach a certain position, the pressure-bearing member 205 will contact the ground after the two grounding rods 204 contact the ground. The two ends of the two rotating rods 207 rotate about the two first horizontal axes 213 and the two second horizontal axes 214 respectively. The two sliding cylinders 212 can slide on the outer surface of the long rod 210. The impact force on the bearing component 205 caused by the ground impact is transmitted through the connecting component 206, causing the two rotating rods 207 to push the two sliding cylinders 212 respectively. This, in turn, compresses the two second elastic elements 211. The two second elastic elements 211 generate elastic force under the compression of the two sliding cylinders 212, and also generate a counterforce, thus achieving a buffering effect and protecting the drone. The elastic force generated by the compression of the two first elastic elements 202 and the two second elastic elements 211 provides a buffering effect at the moment of landing, protecting the drone effectively. To secure the drone to the landing aid device, multiple second positioning rods 302 are inserted into the outer surfaces of multiple first positioning rods 301, thereby... The body 5 is positioned on the landing gear. At this time, the square plate 4 is on the outer surface of the cargo box 303. The external power supply of the first motor 306 is turned on. The two L-shaped rods 309 support the first motor 306, allowing it to be mounted on the cargo box 303. This causes the output shaft of the first motor 306 to drive the threaded rod 304 to rotate. The threaded rod 304 can rotate through the two bearings. The threads inside the two sleeves 308 are opposite. When the threaded rod 304 rotates in different directions, the two sleeves 308 move relative to or in opposite directions on the outer surface of the threaded rod 304. This causes the two insert rods 305 on the two sleeves 308 to move through the two sleeves 308. The two sliding grooves allow multiple moving rods 307 to move.Then, multiple insertion rods 305 are inserted into the limiting holes on the square plate 4 to fix the drone. This method is simple and convenient to use. The two clamping parts 404 can move on both sides of the transmission frame 403. The two handles 405 facilitate the movement of the two clamping parts 404, thereby allowing the two pressure plates 411 to fix the monitor 406. When clamping and fixing the monitor 406, the two protective parts 410 can be foam boards or gaskets, which are not limited here. The two protective parts 410 have a protective function to prevent the monitor 406 from being deformed due to long-term compression. When it is necessary to adjust the angle of the monitor 406, the external power supply of the second motor 407 is turned on, thereby causing the output shaft of the second motor 407 to rotate. This, in turn, causes the straight gear 402 to rotate through the bevel gear 409, thereby changing the angle of the transmission frame 403. Thus, it is not necessary to control the flight angle of the drone; only the rotation of the output shaft of the second motor 407 needs to be controlled, avoiding excessive adjustment of the drone's flight angle, which could lead to it being blown away by the sea breeze.

[0058] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way.
