Description

Technical Field

[0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a unmanned aerial vehicle with take-off and landing protection. Background Art

[0002] Unmanned aerial vehicle is referred to as "UAV" in English. It is an unmanned aircraft controlled by radio remote control equipment and self-contained program control device, or operated completely or intermittently autonomously by an on-board computer. UAVs can be divided into military and civilian use according to their application areas. In the military, UAVs are divided into reconnaissance aircraft and target aircraft. In the civilian field, UAV industry applications are the real rigid demand for UAVs. Their applications in aerial photography, agriculture, plant protection, micro selfies, express delivery and other fields have greatly expanded the use of UAVs themselves. A landing gear buffer device is generally provided at the bottom of the UAV to reduce the impact force during landing.

[0003] When the drone is taking off, the landing gear can be used to assist the drone in taking off and landing. However, the landing gear can only simply assist the drone to stand up and assist the drone to cushion the landing when the drone lands. The take-off and landing protection capabilities are limited, and it cannot increase the protection effect of the drone's body when the drone takes off, causing the drone to easily collide during take-off. It cannot also protect the drone's body after the drone lands, causing the rotor to hinge with weeds or collide with branches. Under the high-speed rotation of the rotor, it will cause greater damage to the rotor, and even cause damage to the drone, and it cannot better protect the drone from taking off and landing.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing drones with take-off and landing protection on the market, and even if they can be solved, they need to be solved with the cooperation of external tools, which cannot achieve the desired effect.

When the machine body 11 needs to descend, if there are weeds and branches on the pre-stop surface, first extend the hollow protection frame 2101 and the four extended retractable hollow plates 2103 through the micro-electric rod 2105, and then directly control the double-outlet air pump 2217 to operate through the control device, and control it directly through the outlet pipe 2218 to the inside of the hollow protection frame 2101, and the air The air inside the heart protection frame 2101 enters the shrinkage hollow plate 2103 through the connecting pipe 2204, and the air enters the first nylon airbag 2205 and the second nylon airbag 2215 through the first air nozzle 2206 and the second air nozzle 2216 respectively. The air continuously enters through the first nylon airbag 2205 and the second nylon airbag 2215, and the first nylon airbag 2205 and the second nylon airbag 2215 directly expand rapidly. The expansion of the first nylon airbag 2205 directly squeezes the two clamping claw frames 2201 outwards, and the clamping claw frames 2201 carry The windbreaker 2202 is flipped upward, and the pressure of the first nylon airbag 2205 directly drives the rare earth magnet plates 2210 on the two windbreakers 2202 to separate, so that the two first nylon airbags 2205 are laid on the left and right sides of the outer periphery of the body 11. Then, as the second nylon airbag 2215 expands, it directly squeezes the protective shell 2203, and the protective shell 2203 can separate the two thin polyester magic tapes 2213. The protective shell 2203 flips outward, so that the second nylon airbag 2215 expands and is laid on the front and rear positions of the body 11, and is separated from the first nylon airbag 2205. Together, the bottom of the fuselage 11 is protected. The volume distance between the first nylon airbag 2205 and the second nylon airbag 2215 after expansion is greater than the wing distance of the fuselage 11. After the fuselage 11 lands, the first nylon airbag 2205 and the second nylon airbag 2215 can contact the ground to protect the fuselage 11, thereby reducing the contact between the wing and the weeds at the bottom to prevent the fuselage from being caught in the weeds. The windbreaker 2202 can increase the connection between the clamp frame 2201, reduce the effect of wind resistance on the clamp frame 2201, and prevent the first nylon airbag 2205 from flying out.

[0052] See also Figure 2 and Fig.10 The bottom surface of each base plate 301 is fixedly connected with an anti-skid pad 302, and the outer surface of each second damper 315 and the upper surface of the contact plate 317 are fixedly connected with a stabilizing ring 314. The anti-skid pad 302 can increase the anti-skid effect of the bottom of the base plate 301, and the stabilizing ring 314 can increase the connection of the second damper 315 to prevent it from falling off.

[0053] The specific implementation of this embodiment is as follows: when the body 11 needs to land, the bottom plate 301 contacts the ground first, and the pressure of the body 11 acts on the primary force-bearing plate 306 through the bottom plate 301 and the external plate 304 first. The primary force-bearing plate 306 drives the double rubber plate 308 upward through the pressure of the body 11, and a part of the pressure can be buffered by the double rubber plate 308. Then, the first clamping plate 309, the rubber buffer column 310 and the second clamping plate 311 are driven upward by the double rubber plate 308 to move upward, and a part of the pressure of the body 11 is reduced by the rubber buffer column 310. Then, the first buffer spring 313 is compressed upward by the second clamping plate 311, and the first buffer spring 313 is compressed upward by the first buffer spring 313. The impact spring 313 buffers the pressure applied to the body 11. If there is still a certain pressure after the primary force plate 306 moves upward for a certain distance, the secondary force plate 307 and the contact plate 317 are released, and the pressure is transmitted to the contact plate 317 through the secondary force plate 307, so that it directly exerts pressure on the second buffer spring 316, and cooperates with the first buffer spring 313 to buffer the pressure of the body 11. After the buffering is completed, the elastic force of the first buffer spring 313 and the second buffer spring 316 reduces the rebound speed through the action of the first damper 312 and the second damper 315, assists in buffering, effectively assists the body 11 to land, and provides landing and grounding protection for the body 11.
