Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) water landing protection technology, specifically to an electric compound wing UAV water landing protection structure. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and their own program control devices, or operated autonomously, either completely or intermittently, by onboard computers.

[0003] Referring to Chinese Patent (Patent No.: CN202320145464.6, Patent Title: A Drone with Water-Related Self-Protection Function), the drone body includes a protective component fixedly installed at the bottom of the drone body. Support legs are fixedly connected to both sides of the bottom of the protective component. A mounting box is fixedly installed at the bottom of the protective component. A base plate is connected to the bottom of the mounting box. Sealing components are provided on both sides of the inner cavity of the mounting box. The protective component includes a protective shell, which is fixedly connected to the bottom of the drone body. The sealing components extend into the inner cavity of the protective shell. Through grooves are provided on both sides of the inner cavity of the protective shell, and floats are slidably connected in the through grooves.

[0004] When the above-mentioned device is in use, when the drone body falls into the water, the float can use its own buoyancy to make the drone body float on the top of the water. This is helpful for locating the drone's position by deploying the float and for prolonging the floating time of the drone body, making it easier to retrieve. However, in actual use, when the drone falls from a high altitude, it will generate a large impact force. As a result, the impact force of the drone when it falls into the water comes into contact with the water surface and resists it, which can easily lead to the drone being damaged by the impact. Therefore, it is difficult to reduce the impact force of the drone when it falls into the water from a high altitude. Summary of the Invention

[0005] The purpose of this invention is to provide a water-resistant structure for an electric compound wing unmanned aerial vehicle (UAV) that reduces the impact force of the UAV upon landing, thus solving the problems in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a water-fall protection structure for an electric compound wing unmanned aerial vehicle (UAV), comprising a UAV body, wherein a buffer mechanism for reducing the impact force of falling into water is provided at one end of the head of the UAV body;

[0007] The buffer mechanism includes a fixed block fixedly connected to one end of the drone's head, a buffer rod movably connected through the fixed block and the inner wall of the drone's body, and a buffer plate fixedly connected to the end of the buffer rod away from the drone's body to resist the impact force of the water surface. Adjusting rods are symmetrically connected to both sides of the buffer rod near the buffer plate via pins. A rectangular groove is formed at the end of each adjusting rod away from the buffer rod. An airbag is housed in the inner wall of the rectangular groove to prevent the drone's body from sinking in the water. The end of each airbag away from the adjusting rod penetrates into the inner wall of the drone's body and is fixedly connected. The adjusting rod is equipped with an adjustment mechanism that allows the two adjusting rods to pull the airbag outwards, and an inflation mechanism on the drone's body for inflating the airbag.

[0008] Preferably, the adjustment mechanism includes a sleeve block fixedly connected to the outer contour of the adjustment rod near the buffer rod end. The opposing sides of the two sleeve blocks are rotatably connected to a support rod that supports the adjustment rod via a pin. The end of the support rod away from the sleeve block is rotatably connected to the two sides of the fixed block at symmetrical positions via a pin.

[0009] Preferably, the inflation mechanism includes first track plates fixedly connected to symmetrical positions on both sides of the inner wall of the drone body. An L-shaped rod is fixedly connected to the end of each first track plate near the buffer rod. A cylindrical shell is fixedly connected to the end of each L-shaped rod away from the first track plate. An exhaust pipe is fixedly connected to the outer contour of each cylindrical shell near the airbag. The ends of the two exhaust pipes away from the cylindrical shells are respectively connected to the inner walls of the two airbags. A one-way exhaust valve is fixedly connected to the inner wall of each exhaust pipe near the cylindrical shell to discharge the gas inside the cylindrical shell into the airbag.

[0010] Preferably, a second track plate is movably connected to the grooves on both first track plates, and a first toothed plate is fixedly connected to the opposite sides of the two second track plates. A gear that meshes with the first toothed plate is rotatably connected to the opposite sides of the first track plates via a pin. A second toothed plate that meshes with the gear is fixedly connected to symmetrical positions on both sides of the buffer rod away from the buffer plate. An auxiliary mechanism is provided on each of the second track plates to quickly push the gas inside the cylindrical shell into the airbag.

[0011] Preferably, the auxiliary mechanism includes sliders movably connected in the grooves on the second track plate, and an inclined block fixedly connected to the end of the second track plate away from the sliders. A limit rod is movably connected through the inclined block, and the end of the limit rod away from the inclined block is fixedly connected to the slider. Springs supporting the slider are fixedly connected to the opposite surfaces of the slider and the inclined block. A moving rod that pushes the gas inside the cylindrical shell into the airbag and a piston plate are fixedly connected to the end of the slider away from the limit rod, and the piston plate penetrates the inner wall of the cylindrical shell and is movably connected.

[0012] Preferably, each of the two first track plates has a fixed rod fixedly connected to its opposite side near the cylindrical housing end. The top of each fixed rod is rotatably connected to an inclined plate that supports and limits the slider via a pin. A torsion spring that supports the inclined plate is fixedly connected to the surface opposite to the fixed rod. A second locking block is fixedly connected to the bottom of the inclined plate near the second track plate end. A first locking block that engages with the second locking block is fixedly connected to the end of the slider near the second locking block.

[0013] Preferably, the adjusting rod is provided with a moving mechanism that drives the drone body to the shore. The moving mechanism includes a fixed plate fixedly connected to the bottom of the adjusting rod near the buffer rod. The fixed plate is rotatably connected to a propeller that drives the drone body to the shore via a pin shaft. The propeller is driven by an electric motor.

[0014] Preferably, a partition plate for placing the control components of the drone body is fixedly connected to the inner wall near the top of the drone body. A push switch is fixedly connected to both sides of the bottom of the partition plate at the corresponding positions of the inclined block. The two push switches are electrically connected to the motors on the two propellers respectively.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. Because the control components of the drone are concentrated in the head, when the drone loses power or control due to a malfunction, it will fall vertically headfirst due to a shift in its center of gravity. The impact force of the fall is significant. When the buffer plate contacts the water surface and resists, it pushes the buffer rod towards the drone body. The buffer rod is supported and limited by the adjusting rod and the sleeve block, and the support rod on the sleeve block and the fixed block. As the buffer plate pushes the buffer rod towards the drone body, the buffer rod, under the action of the support rod, pushes the two adjusting rods to move in opposite directions and unfold. The rectangular groove on the adjusting rod, and the airbag in the rectangular groove, unfolds as the adjusting rod moves in opposite directions. The adjusting rod releases the airbag inside the rectangular groove simultaneously, further increasing the landing area of ​​the drone body and slowing down the sinking speed. The inflation mechanism on the drone body inflates the airbag, so that the airbag can keep the head of the drone body afloat on the water surface.

[0017] 2. As the second track plate moves closer to the cylindrical shell, and the second locking block on the inclined plate is engaged with the first locking block, the second track plate drives the inclined block to move closer to the slider. At this time, the spring is compressed and contracted under the action of the inclined block. When the inclined surface of the inclined block contacts the inclined surface of the inclined plate, the end of the inclined plate away from the fixed rod rotates away from the slider under the action of the inclined block. When the second locking block disengages from the first locking block, the second locking block and the first locking block are released from engagement, and the slider moves quickly under the action of the spring. The piston plate moves rapidly towards the cylindrical shell, while the moving rod, under the action of the slider, quickly pushes the piston plate towards the exhaust pipe. Since the internal air pressure of the cylindrical shell near the exhaust pipe is positive, the one-way exhaust valve is open. This allows the piston plate to quickly fill the inner wall of the airbag with the gas inside the cylindrical shell through the exhaust pipe. The airbag expands as the gas enters, allowing it to lift one end of the drone's head to float on the water surface. This prevents the drone's head from sinking and causing water to enter the drone's internal control components, which could then be damaged.

[0018] Third, with the airbags buoying the drone body on the water surface, the propeller is underwater. By pressing the switch on the partition plate, and with the inclined plate rotating away from the slider under the action of the inclined block, the inclined plate comes into contact with the press switch and is pressed. The press switch is electrically connected to the motor on the propeller, so that the press switch starts the motor, and the propeller rotates to move the drone body towards the shore, so that people can retrieve the drone body from the shore.

[0019] The use of the above structures solves the problem that, in actual use, existing devices generate a large impact force when a drone falls from a high altitude. As a result, the impact force of the drone comes into contact with and resists the water surface, which can easily lead to impact damage to the drone. Therefore, it is difficult to reduce the impact force generated when a drone falls into water from a high altitude. Attached Figure Description

[0031] 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.

[0032] Example 1:

[0033] Please see Figures 1 to 10 The present invention provides a technical solution: a water-fall protection structure for an electric compound wing unmanned aerial vehicle, including a drone body 1, wherein a buffer mechanism for reducing the impact force of falling into water is provided at one end of the head of the drone body 1.

[0034] The buffer mechanism includes a fixed block 2 fixedly connected to one end of the head of the drone body 1, a buffer rod 3 movably connected through the fixed block 2 and the inner wall of the drone body 1, a buffer plate 4 fixedly connected to the end of the buffer rod 3 away from the drone body 1 to resist the impact force of the water surface, and an adjusting rod 5 rotatably connected to both sides of the buffer rod 3 near the buffer plate 4 via a pin shaft, and a rectangular groove 501 opened on the end of the adjusting rod 5 away from the buffer rod 3, the inner wall of the rectangular groove 501 containing an airbag 8 to prevent the drone body 1 from sinking in the water, and the end of the airbag 8 away from the adjusting rod 5 passing through the inner wall of the drone body 1 and fixedly connected, the adjusting rod 5 is provided with an adjusting mechanism that causes the two adjusting rods 5 to pull the airbag 8 outward, and the drone body 1 is provided with an inflation mechanism for inflating the airbag 8.

[0035] The adjustment mechanism includes a sleeve block 6 fixedly connected to the outer contour of the adjustment rod 5 near the buffer rod 3. The opposing sides of the two sleeve blocks 6 are rotatably connected to a support rod 7 that supports the adjustment rod 5 via a pin. The end of the support rod 7 away from the sleeve block 6 is rotatably connected to the two sides of the fixed block 2 via a pin.

[0036] In use, the fixed block 2 on the main body 1 and the buffer rod 3 on the fixed block 2 support and limit the buffer rod 3. The buffer plate 4 on the buffer rod 3 prevents the control components on the main body 1 from falling head-down due to a malfunction and loss of power or control. This impacts the main body 1 with a significant force. When the buffer plate 4 contacts the water surface and resists the impact, it pushes the buffer rod 3 towards the main body 1. The adjusting rod 5 and the sleeve block 6 on the buffer rod 3, along with the support rod 7 on the fixed block 2, allow the support rod 7 to... The adjusting rod 5 provides support and limit. As the buffer plate 4 pushes the buffer rod 3 to move closer to the drone body 1, the buffer rod 3, under the action of the support rod 7, pushes the two adjusting rods 5 to move in opposite directions and unfold. Through the rectangular groove 501 opened on the adjusting rod 5, and the airbag 8 set on the rectangular groove 501, the adjusting rod 5 unfolds as it moves in opposite directions, so that the adjusting rod 5 releases and unfolds the airbag 8 stored inside the rectangular groove 501 simultaneously, further increasing the landing area of ​​the drone body 1 and slowing down the sinking speed of the drone body 1. The inflation mechanism set on the drone body 1 inflates the airbag 8 so that the airbag 8 can float the head of the drone body 1 on the water surface.

[0037] Example 2:

[0038] Building upon Example 1, the following is a further step:

[0039] The inflation mechanism includes a first track plate 9 fixedly connected to both sides of the inner wall of the drone body 1. An L-shaped rod 10 is fixedly connected to the end of the first track plate 9 near the buffer rod 3. A cylindrical shell 11 is fixedly connected to the end of the L-shaped rod 10 away from the first track plate 9. An exhaust pipe 12 is fixedly connected to the outer contour of the cylindrical shell 11 near the airbag 8. The ends of the two exhaust pipes 12 away from the cylindrical shell 11 are respectively connected to the inner walls of the two airbags 8. A one-way exhaust valve 121 is fixedly connected to the inner wall of the exhaust pipe 12 near the cylindrical shell 11 to discharge the gas inside the cylindrical shell 11 into the airbag 8.

[0040] In use, the first track plate 9 is set on the main body 1 of the drone, and the L-shaped rod 10 is set on the first track plate 9. The first track plate 9 supports and fixes the L-shaped rod 10. The cylindrical shell 11 is set on the L-shaped rod 10, and the exhaust pipe 12 is set on the cylindrical shell 11. The exhaust pipe 12 can connect the airbag 8 and the cylindrical shell 11. The one-way exhaust valve 121 set on the exhaust pipe 12 can prevent gas leakage inside the cylindrical shell 11.

[0041] Each of the two first track plates 9 has a second track plate 13 movably connected in its groove. Each of the two second track plates 13 has a first toothed plate 18 fixedly connected to its opposite side. Each of the two first track plates 9 has a gear 19 rotatably connected to its opposite side via a pin, which meshes with the first toothed plate 18. Each of the two sides of the buffer rod 3 away from the buffer plate 4 has a second toothed plate 20 fixedly connected to its opposite side, which meshes with the gear 19. Each of the two track plates 13 is provided with an auxiliary mechanism for quickly pushing the gas inside the cylindrical shell 11 into the airbag 8.

[0042] In use, the first track plate 9 moves and limits the movement of the second track plate 13 via the second track plate 13. The first toothed plate 18 on the second track plate 13 and the gear 19 on the first track plate 9 mesh with the teeth on the first toothed plate 18. The second toothed plate 20 on the buffer rod 3 meshes with the teeth on the gear 19. As the buffer plate 4 pushes the buffer rod 3 to move closer to the drone body 1, the second toothed plate 20 moves closer to the second track plate 13 under the action of the buffer rod 3. The gear 19 rotates on a fixed axis under the action of the second toothed plate 20, which enables the first toothed plate 18 to drive the second track plate 13 to move closer to the cylindrical shell 11 under the action of the gear 19. The auxiliary mechanism on the second track plate 13 can quickly push the gas inside the cylindrical shell 11 to the inner wall of the airbag 8.

[0043] Example 3:

[0044] Building upon Example 2, the following is a further step:

[0045] The auxiliary mechanism includes sliders 14 movably connected in the grooves on the second track plate 13, and an inclined block 15 fixedly connected to the end of the second track plate 13 away from the sliders 14. A limit rod 16 is movably connected through the inclined block 15, and the end of the limit rod 16 away from the inclined block 15 is fixedly connected to the slider 14. Springs 17 supporting the slider 14 are fixedly connected to the opposite surfaces of the slider 14 and the inclined block 15. A moving rod 25 that pushes the gas inside the cylindrical shell 11 into the airbag 8 and a piston plate 26 are fixedly connected to the end of the slider 14 away from the limit rod 16. The piston plate 26 penetrates the inner wall of the cylindrical shell 11 and is movably connected.

[0046] Each of the two first track plates 9 is fixedly connected to a fixed rod 22 on the opposite side near the cylindrical housing 11. The top of each fixed rod 22 is rotatably connected to an inclined plate 23 that supports and limits the slider 14 via a pin. A torsion spring 24 is fixedly connected to the opposite surface of the inclined plate 23 and the fixed rod 22 to support the inclined plate 23. A second locking block 231 is fixedly connected to the bottom of the inclined plate 23 near the second track plate 13. A first locking block 141 that engages with the second locking block 231 is fixedly connected to the end of the slider 14 near the second locking block 231.

[0047] In use, the slider 14 on the second track plate 13 moves and limits the movement of the second track plate 13. The inclined block 15 on the second track plate 13 and the limiting rod 16 on the inclined block 15 support and limit the limiting rod 16. The spring 17 on the limiting rod 16 supports and limits the slider 14. The moving rod 25 and the piston plate 26 on the slider 14 support the piston plate 26. As the second track plate 13 moves toward the cylindrical housing 11, the second track plate 13 can drive the above mechanism to move synchronously.

[0048] The fixed rod 22 on the first track plate 9, and the inclined plate 23 and torsion spring 24 on the fixed rod 22, can support and fix the position of the inclined plate 23. The inclined plate 23 and the slider 14 are then in a horizontal state. The second locking block 231 on the inclined plate 23 and the first locking block 141 on the slider 14 engage with each other. As the second track plate 13 moves towards the cylindrical housing 11, and the second locking block 231 and the first locking block 141 on the inclined plate 23 are engaged, the second track plate 13 drives the inclined block 15 towards the slider 14. At this time, the spring 17 is compressed and contracted under the action of the inclined block 15. When the inclined surface of the inclined block 15 contacts the inclined surface of the inclined plate 23, the end of the inclined plate 23 away from the fixed rod 22 is tilted towards the inclined plate 23 under the action of the inclined block 15. Rotating away from slider 14, when the second locking block 231 disengages from the first locking block 141, the second locking block 231 and the first locking block 141 are released from their engagement state. Then, under the action of spring 17, slider 14 moves rapidly towards the cylindrical housing 11. At the same time, under the action of slider 14, moving rod 25 pushes piston plate 26 towards the exhaust pipe 12. Since the internal air pressure of the cylindrical housing 11 near the exhaust pipe 12 is positive, the one-way exhaust valve 121 is open. This allows piston plate 26 to quickly fill the inner wall of airbag 8 with gas from inside the cylindrical housing 11 through exhaust pipe 12. Airbag 8 expands as gas enters, allowing airbag 8 to lift one end of the drone body 1's head to float on the water surface. This prevents the drone body 1's head from sinking and causing water to enter the drone body 1, which could damage the control components inside the drone body 1.

[0049] Example 4:

[0050] Building upon Example 3, the following is a further step:

[0051] The adjusting rod 5 is equipped with a moving mechanism that drives the drone body 1 to the shore. The moving mechanism includes a fixed plate 27 fixedly connected to the bottom of the adjusting rod 5 near the buffer rod 3. The fixed plate 27 is rotatably connected to a propeller 28 that drives the drone body 1 to the shore via a pin shaft. The propeller 28 is driven by a motor after being powered on.

[0052] The inner wall of the drone body 1 near the top is fixedly connected to a partition plate 30 for placing the control components of the drone body 1. On both sides of the bottom of the partition plate 30, corresponding to the inclined block 15, a push switch 29 is fixedly connected. The two push switches 29 are electrically connected to the motors on the two propellers 28 respectively.

[0053] In use, the control components inside the drone body 1 can be placed on the partition plate 30 provided on the drone body 1. The drone body 1 is floated on the water surface by the fixed plate 27 provided on the adjusting rod 5 and the propeller 28 provided on the fixed plate 27, along with the airbag 8. At this time, the propeller 28 is located underwater. The push switch 29 provided on the partition plate 30, along with the inclined plate 23 rotating away from the slider 14 under the action of the inclined block 15, makes the inclined plate 23 contact the push switch 29 and press it. The push switch 29 is electrically connected to the motor on the propeller 28, so that the push switch 29 starts the motor. Thus, the propeller 28 rotates and can move the drone body 1 towards the shore, so that personnel can retrieve the drone body 1 from the shore.

[0054] Furthermore, the existing device can reduce the impact force generated by a fall, is easy to use, and is better than traditional products.

[0055] The standard parts used in this embodiment can be purchased directly from the market, while the non-standard structural parts described in the specification and drawings can be processed directly based on existing technical knowledge without any doubt. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0056] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
