Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] The present invention will be further described below with reference to the embodiments.

[0032] A heavy-load, long-endurance tilt-rotor UAV of this embodiment, such as Figures 1 to 5 As shown, it includes a drone body 1, a buffer mechanism is provided on the top of the drone body 1, and a storage component is provided above the buffer mechanism;

[0033] The buffer mechanism includes a mounting box 21 and a rotating shaft 22. The buffer mechanism is used to reduce the resistance of the drone body 1 when it rises and to increase the contact area with the air when the drone body 1 descends.

[0034] The storage component includes a storage compartment 31 , which is used to disperse the resistance encountered by the drone body 1 when it rises, and to change the shape of the storage component according to the items carried by the drone body 1 .

[0035] As a preferred implementation in this embodiment, Figure 3 、 Figure 4 and Figure 5As shown, the mounting box 21 is fixedly connected to the top of the drone body 1, the rotating shaft 22 is rotatably connected to the inside of the mounting box 21, the end of the rotating shaft 22 away from the inner wall of the mounting box 21 is fixedly connected to the bevel gear 1 23, the interior of the mounting box 21 is rotatably connected to the transmission shaft 25, the outer surface of the transmission shaft 25 is fixedly connected to the bevel gear 2 24, the bevel gear 1 23 and the bevel gear 2 24 are meshed for transmission, the two ends of the transmission shaft 25 are fixedly connected to the driving block 26, the end of the driving block 26 away from the transmission shaft 25 is fixedly connected to the buffer plate 27, the outer surface of the buffer plate 27 is fixedly connected to the boss 28, the boss 28 The end away from the buffer plate 27 is hemispherical. The bottom of the storage bin 31 is fixedly connected to the top of the mounting box 21. Doors 32 are provided on either side of the storage bin 31. Positioning seats 36 are symmetrically fixedly connected to the outer surface of the storage bin 31. Positioning blocks 33 are symmetrically fixedly connected to the outer surface of the door 32. The positioning blocks 33 are inserted into the interior of the positioning seats 36. Receiving slots are defined on either side of the positioning blocks 33. Elastic columns 34 are fixedly connected to the inner walls of the slots. An arcuate block 35 is fixedly connected to the end of the elastic column 34 away from the inner wall of the slot. The interior of the positioning seat 36 defines an arcuate slot that mates with the arcuate block 35. As the drone body 1 descends, the buffer plate 27 increases the contact area between the drone body 1 and the air, thereby reducing the drone body 1's descent speed.

[0036] Working principle:

[0037] Initial limit:

[0038] Before using the present invention, the user needs to install the micro motor inside the installation box 21, connect the output shaft of the micro motor to the end of the rotating shaft 22 away from the bevel gear 1 23, and electrically connect the micro motor to the remote control switch of the drone body 1;

[0039] like Figures 1 to 5 As shown, when the drone body 1 is ascending, the buffer plate 27 drives the protrusion 28 upward. At this time, the drone body 1 reduces the overall upward resistance through the buffer plate 27 and the protrusion 28 during the ascending process and disperses the resistance, thereby reducing the energy consumed by the drone body 1 when carrying objects and extending the flight time of the drone body 1. In addition, the buffer plate 27 cooperates with the storage bin 31 to disperse the air resistance before it comes into contact with the air resistance, thereby allowing the drone body 1 to ascend more stably.

[0040] When the unmanned aerial vehicle body 1 fails, the user turns on the power supply of the micro motor when operating the remote control switch of the unmanned aerial vehicle body 1, the output shaft of the micro motor drives the rotating shaft 22 to rotate, and the rotating angle is 90 degrees; when the rotating shaft 22 rotates, the bevel gear one 23 rotates, and since the bevel gear one 23 is in meshing transmission with the bevel gear two 24, the bevel gear one 23 drives the bevel gear two 24 to rotate when rotating; the bevel gear two 24 drives the transmission shaft 25 to rotate when rotating; the transmission shaft 25 drives the driving block 26 to rotate when rotating; the driving block 26 drives the buffer plate 27 to rotate when rotating; the buffer plate 27 drives the convex column 28 to rotate when rotating, so that the buffer plate 27 originally in the vertical state is changed to the horizontal state; the buffer plate 27 enlarges the contact area of the unmanned aerial vehicle body 1 and the air, thereby reducing the descending speed of the unmanned aerial vehicle body 1, so that the unmanned aerial vehicle body 1 can stably and safely land on the ground, thereby ensuring the safety of the unmanned aerial vehicle body 1 during descending, thereby prolonging the service life of the unmanned aerial vehicle body 1; and the bottom end of the storage bin 31 can also enlarge the contact area of the unmanned aerial vehicle body 1 when the unmanned aerial vehicle body 1 descends, thereby improving the buffering effect of the buffering mechanism.

[0041] When the user needs to disassemble the bin door 32 and the storage bin 31, the user only needs to manually pull the bin door 32 away from the storage bin 31, so that the bin door 32 moves away from the storage bin 31 and drives the positioning block 33 to move out of the inside of the positioning seat 36; when the positioning block 33 moves out of the inside of the positioning seat 36, the arc-shaped block 35 moves out of the arc-shaped groove in the inside of the positioning seat 36; at this time, the arc-shaped block 35 is extruded from the inside of the positioning seat 36, so that the arc-shaped block 35 is extruded into the receiving groove in the arc-shaped block 35; when the arc-shaped block 35 enters the receiving groove, the elastic column 34 is pressed, so that the elastic column 34 is deformed, so that the arc-shaped block 35 is popped out by the elastic force of the elastic column 34 in the subsequent process, so that the arc-shaped block 35 moves out of the inside of the positioning seat 36, thereby disassembling the bin door 32 and the storage bin 31.

[0042] Conversely, when the user needs to install the bin door 32 at both ends of the storage bin 31, the user only needs to operate according to the above steps, and the operation direction is opposite to the above.

[0043] The storage bin 31 and the bin door 32 are inserted and clamped between the positioning block 33 and the positioning seat 36, so that the user can freely disassemble the bin door 32, so that the unmanned aerial vehicle body 1 can change the form of the storage bin 31 according to the types of carried objects, thereby expanding the application range of the storage bin 31, so that the user can select different storage spaces for different objects when using the unmanned aerial vehicle body 1, which is helpful to maintain the stability of the objects carried on the top end of the unmanned aerial vehicle body 1.

[0044] The above examples are only used to illustrate the technical solutions of the present application, and are not intended to limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
