Rocker UAV can quickly remove the landing gear

Abstract

The invention relates to a rocker-arm type unmanned aerial vehicle with quick-release landing gear. The pillar of the landing gear is composed of an upper pillar and a lower pillar that are spirally connected. The connecting end of the pillar is connected with a direction adjusting disc and a positioning pin for rotating and positioning, and an undercarriage anti-rebound mechanism is provided at the junction of the wheel fork fork groove and the lower pillar. The invention adjusts the height of the pillar through thread rotation, and realizes the adjustment of the direction of the front wheel through fine adjustment of the thread. The problem of height adjustment is solved by the screw connection of the upper and lower pillars. The rotation positioning of the direction adjusting disc and the positioning pin solves the problem of fine-tuning the direction. The anti-rebound mechanism avoids the rebound of the tension spring and prevents the rebound of the landing gear. It ensures the attitude of the UAV's taxiing and take-off under different take-off weights, and overcomes the effects of the aircraft's ground taxiing and yaw caused by the manufacturing and installation errors of the nose landing gear. It has the characteristics of easy maintenance and inspection, good reliability, quick and convenient disassembly, shock absorption and buffering, and anti-rebound.

Description

The technical field of quick-release landing gear of rocker-arm unmanned aerial vehicles The present invention relates to a kind of ultralight aircraft landing gear, more specifically, the present invention relates to a kind of The rocker landing gear of the aircraft. technical background Conventional undercarriage is the oil-pneumatic undercarriage with turning function, but for ultra-small aircraft, especially unmanned As far as aircraft is concerned, conventional landing gear with oil-air cushioning far exceeds the heavy weight and high cost requirements of ultra-small aircraft. Small unmanned aerial vehicle landing gear in the prior art adopts skid type or rocker type / leaf spring type front landing gear usually structure. Rocker arm type and leaf spring type nose landing gear are common structural forms of wheeled buffer devices for small UAVs. skid type, air The capsule landing gear can only be recovered by a single parachute, and it does not have height, dire...

AI Technical Summary

Problems solved by technology

The leaf spring front landing gear is fixed outside the front fuselage, and it cannot overcome the constraints in the absence of a turning system.

The ground roll and yaw of the aircraft caused by manufacturing and assembly errors, and
