Title: CUSHIONING LEG SUPPORT FOR SMALL UNMANNED AERIAL VEHICLE
Abstract:
A cushioning leg support for a small unmanned aerial vehicle, comprising a mounting base (1) and two supporting rods (2) which are arranged in parallel; arc connecting rods (3) are vertically and fixedly arranged on the supporting rods (2); also comprised is a sleeve (4) sheathed on ends of the two connecting rods (3); The ends of the two connecting rods (3) are connected by means of a spring (30); a surface of the connecting rods (3) is provided with a stop ring (31); an inner wall of the sleeve (4) is provided with a plurality of elastic ribs (40) matching the stop ring (31); a lower surface of the mounting base (1) is provided with a cavity (10) matching an outline of the sleeve (4) and a cover plate. When the unmanned aerial vehicle lands, the supporting rods (2) make contact with the ground, the vibration generated is transmitted by means of the arc connecting rods (3), and the vibration is cushioned and damped by means of the spring (30) and the elastic ribs (40), thereby largely reducing the vibration effect during landing and preventing the vehicle from rolling over. The overall structure of the invention is simple, and the cost thereof is low.
