[0034] 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.
[0035] like Figures 1-11 As shown, the technical solution adopted by the present invention is as follows: A cruise heavy-load unmanned aerial vehicle includes a body 1, a long box 7 and a landing support 21.
[0036] The long box 7 is positioned below the main body 1 and is connected to the main body 1 via ropes 6. In this embodiment, two ropes 6 are provided, symmetrically arranged, to ensure a more stable connection between the long box 7 and the main body 1.
[0037] The machine body 1 is equipped with a winding assembly for winding up the rope 6. For example... Figure 4 As shown, the winding assembly includes a winding reel 5. A winding chamber is provided inside the machine body 1, and two fixed plates 2 are fixedly installed inside the winding chamber. A rotating shaft 4 is rotatably connected between the two fixed plates 2. A motor 3 is fixedly installed on one of the fixed plates 2, and the output shaft of the motor 3 is fixedly connected to one end of the rotating shaft 4. Two winding reels 5 are fixedly sleeved on the rotating shaft 4, and each of the two winding reels 5 corresponds to one of the two ropes 6. One end of the rope 6 is fixedly connected to the corresponding winding reel 5, and the other end of the rope 6 slides through the lower part of the machine body 1 and extends outside the machine body 1 to connect with the long box 7. The winding assembly winds or unwinds the rope 6, thereby causing the long box 7 to move closer to or further away from the machine body 1.
[0038] like Figure 8 As shown, two clamping plates 9 are elastically slidably arranged inside the long box 7. The two clamping plates 9 are symmetrically arranged and are arranged along the length direction of the long box 7. A tension spring 11 is fixedly connected to the outer side of the clamping plate 9. A tension spring groove is opened on the inner wall of the long box 7 at a position corresponding to the tension spring 11. The end of the tension spring 11 away from the clamping plate 9 extends into the tension spring groove and is fixedly connected to the long box 7.
[0039] Two first ball-head slide rods 12 are fixedly connected to the outer side of each clamping plate 9. The two first ball-head slide rods 12 on the same clamping plate 9 are spaced apart along the length of the clamping plate 9. The end of the first ball-head slide rod 12 away from the clamping plate 9 slides through the side wall of the long box 7 and extends to the outside of the long box 7. Initially, under the action of the tension spring 11, the clamping plate 9 abuts against the inner wall of the long box 7, and the first ball-head slide rod 12 extends to the outside of the long box 7.
[0040] A rubber layer 10 is fixedly connected to the inner side of the clamping plate 9. When the two clamping plates 9 are close to each other and clamp the goods inside the long box 7, the clamping plates 9 contact the goods through the rubber layer 10, thus protecting the goods.
[0041] like Figure 3 As shown, a lid 8 is rotatably mounted on one side of the long container 7. Opening the lid 8 facilitates loading goods into the long container 7. A latch is provided between the lid 8 and the long container 7 to lock the lid 8 in place.
[0042] A rotating ring 14 is rotatably mounted on the outer circumference of the body 1. Specifically, two arc-shaped grooves 16 are symmetrically formed on the outer circumference of the body 1. A slider 15 is slidably disposed within the arc-shaped grooves 16, and the slider 15 is fixedly connected to the rotating ring 14. The slider 15 slides along the arc-shaped grooves 16, and the slider 15 drives the rotating ring 14 to rotate around the axis of the body 1. The slider 15 slides from one end of the arc-shaped groove 16 to the other end, and the rotating ring 14 rotates 90 degrees around the body 1.
[0043] A torsion spring is provided between the rotating ring 14 and the body 1 to reset the rotating ring 14.
[0044] A ring plate 17 is fixedly connected to the inner side of the rotating ring 14, and two arc-shaped inclined blocks 18 are fixedly installed on the lower end surface of the ring plate 17. For example... Figure 7 As shown, the thickness of the arc-shaped inclined block 18 gradually increases from one end to the other. Two second ball-head slide rods 19 are slidably connected to the bottom of the body 1, each corresponding to one of the two arc-shaped inclined blocks 18. The second ball-head slide rods 19 are fitted into their respective arc-shaped inclined blocks 18. Two symmetrically arranged limiting grooves 20 are formed on the second ball-head slide rods 19. A through hole is formed at the bottom of the body 1 to mate with the second ball-head slide rod 19. A protrusion is fixed to the inner wall of the through hole, slidingly engaging with the limiting groove 20. The protrusion is slidably positioned within the corresponding limiting groove 20, thus limiting the movement of the second ball-head slide rod 19.
[0045] When the long box 7 approaches the body 1, the long box 7 presses against the second ball head slide rod 19, and the second ball head slide rod 19 acts on the arc-shaped inclined block 18, causing the rotating ring 14 to rotate around the axis of the body 1.
[0046] Two landing supports 21 are rotatably mounted on the outer circumference of the rotating ring 14. The landing supports 21 are located on both sides of the rotating ring 14. Specifically, the landing supports 21 are rotatably connected to the rotating ring 14 via shafts, and the axis of the shafts is perpendicular to the axis of the rotating shaft 4.
[0047] The landing support 21 includes a long vertical rod 211, a horizontal rod 212, and a short vertical rod 213. One end of the long vertical rod 211 is rotatably connected to the swivel ring 14 via a shaft. The other end of the long vertical rod 211 is fixedly connected to one end of the horizontal rod 212, and the other end of the horizontal rod 212 is fixedly connected to one end of the short vertical rod 213. The width of the landing support 21, i.e., the distance between the long vertical rod 211 and the short vertical rod 213, is adapted to the width of the long box 7.
[0048] A drive mechanism is mounted on the rotating ring 14 to drive the landing support 21 to rotate around the shaft. The drive mechanism includes an electrically operated telescopic rod 22, which is hinged to the rotating ring 14 via a first hinge axis, and the telescopic end of the electrically operated telescopic rod 22 is hinged to the long vertical rod 211 via a second hinge axis. Both the first and second hinge axes are parallel to the shaft.
[0049] The electric telescopic rod 22 and the torsion spring both adopt existing technologies, and those skilled in the art can make conventional selections or make customizations according to actual needs.
[0050] Initially, the landing support 21 is positioned on one side of the long container 7, with the crossbar 212 parallel to the length of the long container 7. This causes the rotating ring 14 to rotate 90 degrees around the body 1, and the landing support 21 to rotate 90 degrees around the body 1, so that the crossbar 212 rotates to the bottom of the long container 7 and is parallel to its width. At this time, the long vertical bar 211 and the short vertical bar 213 on the same landing support 21 are positioned on opposite sides of the long container 7. Then, the driving component drives the landing support 21 to rotate around the axis, and the crossbar 212 gradually approaches the long container 7 and moves outwards. This continues until the crossbar 212 abuts against the long container 7, providing support. At this point, the long vertical bar 211 and the short vertical bar 213 press against the corresponding first ball-head slide bar 12, causing the first ball-head slide bar 12 to retract into the long container 7, thus clamping and securing the cargo inside the long container 7 with the two clamping plates 9.
[0051] like Figure 10 As shown, two sets of support legs 13 are fixedly installed at the bottom of the long box 7, with the two sets of support legs 13 located on the left and right sides of the long box 7 respectively. The two sets of support legs 13 correspond one-to-one with the two crossbars 212. Each set includes two support legs 13. When the crossbar 212 abuts against the bottom of the long box 7, the crossbar 212 abuts against the inner side of the corresponding support leg 13, thereby limiting the movement of the long box 7 and preventing it from moving left or right.
[0052] Working principle: Initially, the landing support 21 contacts the ground, supporting the fuselage 1. Under the action of the tension spring 11, the clamping plate 9 abuts against the inner wall of the long box 7. The first ball joint slide rod 12 extends to the outside of the long box 7. The torsion spring is in its natural state, and the slider 15 is at one end of the arc-shaped slide groove 16. The second ball joint slide rod 19 extends to the outside of the fuselage 1. The crossbar 212 is parallel to the length direction of the long box 7, and the two landing supports 21 are located on both sides of the long box 7. The long vertical bar 211, the crossbar 212, and the short vertical bar 213 in the same landing support 21 are located on the same side of the long box 7.
[0053] When in use, open the lid 8, load the goods into the long box 7, then close the lid 8 and lock it.
[0054] Then, control the machine body 1 to rise to a certain height and hover, at which point the two crossbars 212 are not in contact with the ground. Start the motor 3, which drives the rotating shaft 4 to rotate, and the winding wheel 5 rotates to wind the rope 6. The rope 6 drives the long box 7 to move upward, so that the long box 7 gradually approaches the bottom of the machine body 1.
[0055] As the winding assembly winds up, the long box 7 moves upward, contacting the second ball-head slide rod 19 and pushing it into the body 1. The second ball-head slide rod 19 presses against the arc-shaped inclined block 18, forcing it to move, thus causing the rotating ring 14 to rotate around the axis of the body 1, and the slider 15 to slide towards the other end of the arc-shaped groove 16. The torsion spring elastically deforms. The rotating ring 14 simultaneously drives the landing bracket 21 to rotate.
[0056] When the long box 7 contacts the bottom of the body 1, the motor 3 shuts off, the slider 15 slides to the other end of the arc-shaped groove 16, and the rotating ring 14 and the landing bracket 21 stop rotating. At this time, the crossbar 212 is directly below the long box 7 and parallel to the width direction of the long box 7. The long vertical bar 211 and the short vertical bar 213 in the same landing bracket 21 are respectively located on both sides of the long box 7. At this time, the long vertical bar 211 and the short vertical bar 213 are not in contact with the long box 7.
[0057] It should be noted that when the long box 7 contacts the lower end of the second ball-head slide bar 19, the upper end of the short vertical bar 213 is lower than the ground of the long box 7. Therefore, as the long box 7 moves upward and causes the rotating ring 14 to rotate, causing the horizontal bar 212 and the short vertical bar 213 to move, the short vertical bar 213 and the long box 7 will not interfere with each other.
[0058] Then, the electric telescopic rod 22 is activated, causing it to extend. The electric telescopic rod 22 pushes the landing bracket 21 to rotate around its axis. The horizontal bar 212 gradually approaches the long box 7, while the two horizontal bars 212 gradually move away from each other. The long vertical bar 211 and the short vertical bar 213 gradually approach their respective first ball-head slide bars 12, pushing the first ball-head slide bars 12 into the long box 7. The first ball-head slide bars 12 push the clamping plate 9, causing the clamping plate 9 to clamp the goods inside the long box 7, thus securing the goods.
[0059] The electric telescopic rod 22 closes when the crossbar 212 abuts against the long box 7.
[0060] At this time, as Figure 9 , Figure 10 as well as Figure 11 As shown, the long vertical rod 211 and the short vertical rod 213 abut against the corresponding first ball-head slide rod 12, so that the clamping plate 9 keeps holding the goods.
[0061] The crossbar 212 abuts against the lower end face of the long box 7, providing support for it. Simultaneously, the upper end face of the long box 7 abuts against the bottom of the fuselage 1, preventing it from moving vertically. The long vertical bar 211 and short vertical bar 213 on the same landing support 21 abut against both sides of the long box 7, making it difficult for it to move forward or backward. At this time, the crossbar 212 abuts against the inside of the support leg 13, making it difficult for the long box 7 to move left or right. In this way, the long box 7 is limited in multiple directions, preventing it from moving and ensuring it is more securely fixed to the fuselage 1.
[0062] At this point, the two crossbars 212 are positioned on the left and right sides of the lower end face of the long box 7, respectively, increasing the support area for the long box 7 and making it more stable. Furthermore, the middle of the upper end face of the long box 7 abuts against the fuselage 1, thus the three clamping points of the long box 7 are distributed in an isosceles triangle, further stabilizing the long box 7. This helps ensure the stability of the long box 7 during flight transport.
[0063] Once the aircraft 1 reaches the desired position, if that position does not support a stable landing (e.g., due to steep terrain, uneven terrain, ground space occupied by other objects, or on water), the aircraft 1 will hover at a certain altitude. Then, the electric telescopic boom 22 will be shortened, causing the landing support 21 to rotate around its axis. The crossbar 212 will gradually move away from the lower end face of the long container 7 until the electric telescopic boom 22 returns to its initial state. At this point, both the crossbar 212 and the short vertical bar 213 will disengage from the long container 7. At this time, the first ball joint slide bar 12 loses its restraint from the long vertical bar 211 or the short vertical bar 213, and under the action of the tension spring 11, the clamping plate 9 moves away from the cargo, releasing its grip.
[0064] Next, motor 3 is started, causing the winding reel 5 to unload the rope 6, and the long box 7 moves downward under its own weight. The long box 7 gradually releases pressure on the second ball-head slide rod 19, and the rotating ring 14, under the action of the torsion spring, resets and rotates, causing the landing bracket 21 to reset. This continues until the long box 7 disengages from the second ball-head slide rod 19, and both the rotating ring 14 and the landing bracket 21 return to their initial states.
[0065] Afterwards, the winding reel 5 continues to release the line until the long box 7 falls to the ground, after which the staff opens the box lid 8 and takes out the goods.
[0066] Then, the winding reel 5 is wound up, causing the long box 7 to move upwards. The long box 7 pushes the second ball-head slide bar 19 upwards, which in turn rotates the swivel ring 14, causing the crossbar 212 to rotate directly below the long box 7 and parallel to its width. Afterwards, the landing support 21 rotates around its axis, causing the crossbar 212 to abut against the long box 7, supporting it and securing the long box 7 back stably to the fuselage 1. The fuselage 1 can then be flown away.
[0067] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
