Cushioned landing gear for rotorcraft UAVs

Abstract

The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a buffer landing gear for a rotor-type unmanned aerial vehicle, which includes a housing with long space-limiting slots on both sides, a driving device arranged in the housing, and a driving device arranged in the housing. For the lifting and folding frame below, buffer devices are provided on both sides of the drive device, and the buffer device includes a spring tube, a spring frame slidingly sleeved on the spring tube, a lead screw connected to the drive device and a lead screw connected to the drive device. A matching moving nut, one end of the spring tube is provided with a spring stop ring, the other end is fixedly connected with the moving nut, the spring tube is covered with a buffer spring, and the buffer spring is located between the spring stop ring and the spring frame, Both the moving nut and the spring blocking ring are outwardly extended with a limiting block matched with the limiting long groove, and the lifting and folding frame includes a folding unit, and the folding unit includes two connecting rods hinged to each other, and the two The top ends of the connecting rods are respectively hinged with the bottom ends of the corresponding spring holders.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a buffer landing gear for a rotary-wing unmanned aerial vehicle. Background technique [0002] At present, UAVs are used more and more widely, including fixed-wing UAVs and rotary-wing UAVs. The former has strong endurance, fast flight speed, good concealment, and can work at high altitudes. It has been widely used in reconnaissance. Aerial photography, agriculture, weather monitoring and many other military or civilian fields; the latter is a relatively small, stable flight, small UAV that can hover in the air or track slowly, due to its excellent flight performance and good reliability The controllability is deeply loved by civilian amateurs, and it occupies a huge market in many public safety fields such as aerial photography and real-time monitoring, as well as in the field of civilian entertainment. [0003] At present, the landing gear designed...
