Problems solved by technology

[0004] For UAVs used in material rescue and material transportation, when using UAVs for material transportation, the weight of the materials increases the total weight of the UAV, which increases the inertia of the UAV when it lands. , so that the unmanned aerial vehicle transporting materials is subject to a greater impact when it lands, which is easy to cause damage to the unmanned aerial vehicle and reduce its service life. However, the landing gear in the prior art cannot effectively target the unmanned transportation of materials The machine is well protected, but the functionality is poor

Embodiment 1

[0059] see Figure 1-13 , a pneumatic reverse thrust landing gear for unmanned aerial vehicles, including a load-bearing base plate 101 fixedly installed on the lower end of the unmanned aerial vehicle body 1, a plurality of driving structures 102 are installed on the upper end of the load-bearing base plate 101, and a visual structure 103 is installed on the front end of the load-bearing base plate 101 An empennage structure 104 is installed at the rear end of the load-bearing base plate 101, and a set of reverse thrust landing gear assemblies 2 are connected to the left and right ends of the load-bearing base plate 101. Between the two sets of reverse thrust landing gear assemblies 2, the lower end of the reverse thrust landing gear assemblies 2 is connected with a pneumatic reverse thrust buffer assembly 4, and the air-inflated reverse thrust assembly 3 communicates with the pneumatic reverse thrust cushion assembly 4 through the reverse thrust landing gear assembly 2. conn...

Embodiment 2

[0067] see Figure 1-13 , where the same or corresponding components as those in Embodiment 1 use the corresponding reference numerals as in Embodiment 1, and for the sake of simplicity, only the differences from Embodiment 1 will be described below. The difference between this embodiment 2 and embodiment 1 is: please refer to figure 1 and Figure 10-12 , the air pressure expander 6 is fixedly installed in the anti-thrust air hole, the air pressure expander 6 includes a conical air intake pipe 601, the upper end of the conical air intake pipe 601 is connected with the rubber buffer post 403, and the lower end of the conical air intake pipe 601 is fixedly connected with a peach The lower end of the peach-shaped pressurizing tube 602 is fixedly connected with a pressurized air outlet pipe 603, and the lower end of the pressurized air outlet pipe 603 extends to the outside of the rubber buffer post 403. By installing the air pressure expander 6 in the reverse thrust air hole, t...

Embodiment 3

[0071] see Figure 1-13 , where the same or corresponding components as those in Embodiment 1 use the corresponding reference numerals as in Embodiment 1, and for the sake of simplicity, only the differences from Embodiment 1 will be described below. The difference between this embodiment 3 and embodiment 1 is: please refer to figure 1 and Figure 10 The lower end of the rubber buffer column 403 is connected with a plurality of horizontal balance assemblies 5, and the horizontal balance assembly 5 includes a balance ball head 501. The lower end of the rubber buffer column 403 is provided with a plurality of ball grooves, and the ball grooves are rotationally connected with balance ball heads 501. The lower end of the ball head 501 is fixedly connected with an arc balance plate 502 through a connecting rod, and the inner arc diameter of the arc balance plate 502 is at least 3 times of the outer diameter of the rubber buffer column 403 . By setting the horizontal balance compo...

Abstract

The invention discloses a pneumatic reverse thrust type undercarriage for an unmanned aerial vehicle and a using method of the pneumatic reverse thrust type undercarriage, and belongs to the field of unmanned aerial vehicles. The pneumatic reverse thrust type undercarriage for the unmanned aerial vehicle comprises a bearing bottom plate fixedly mounted at the lower end of an unmanned aerial vehicle body, and a plurality of driving structures are mounted at the upper end of the bearing bottom plate; a visual structure is installed at the front end of the bearing bottom plate, an air-blowing reverse thrust assembly can be arranged at the lower end of the bearing bottom plate, and a pneumatic reverse thrust type buffer assembly is arranged at the lower end of a reverse thrust undercarriage assembly, so that the air-blowing reverse thrust assembly and the pneumatic reverse thrust type buffer assembly are matched; when the unmanned aerial vehicle body with supplies lands, the pneumatic reverse thrust type buffer assembly blows air to the ground, reverse thrust is effectively achieved, the inertia of the unmanned aerial vehicle body is buffered, the impact force of landing of the unmanned aerial vehicle body is reduced, the landing stability of the unmanned aerial vehicle body is improved, the unmanned aerial vehicle body with materials is effectively protected, and the functionality of the reverse thrust undercarriage assembly is improved.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, and more specifically, relates to a pneumatic reverse thrust landing gear for an unmanned aerial vehicle and a use method thereof. Background technique [0002] Unmanned aircraft, referred to as "unmanned aerial vehicle" ("UAV"), is an unmanned aircraft controlled by radio remote control equipment and its own program control device. UAV is actually a general term for unmanned aerial vehicles. From a technical point of view, it can be divided into: unmanned fixed-wing aircraft, unmanned vertical take-off and landing aircraft, unmanned airship, unmanned helicopter, unmanned multi-rotor aircraft, unmanned Paraplane etc. UAVs are also widely used in civilian use. At present, they are widely used in aerial photography, agriculture, plant protection, micro selfie, express delivery, disaster relief, observation of wild animals, monitoring of infectious diseases, surveying and mapping, news repor...
