Abstract
The utility model provides an unmanned aerial vehicle undercarriage, the main part is the unmanned aerial vehicle bottom plate, the rotation axis is installed respectively on four summits of unmanned aerial vehicle bottom plate, rotation axis centre of a circle position is opened there is the round hole, the rotation axis winds round hole axial rotation, the great one end of rotation axis side one end joint support frame cross sectional area, the telescopic structure of support frame for can change length, two sections butt joint positions internally mounted of support frame have the cushion ball, the less one end fixed mounting of support frame cross sectional area has titanium alloy hemisphere supporting legs. Compared with the prior art, compare with the correlation technique, the utility model provides a pair of unmanned aerial vehicle undercarriage has following advantage: the buffer ball is adopted for buffering, so that mechanical fatigue is not easy to generate, the buffer force is stable, and the replacement is convenient; adopt titanium alloy hemisphere support frame, when guaranteeing sufficient structural strength, have lighter weight, reduce unmanned aerial vehicle's heavy burden.
Description
[ technical field ] A method for producing a semiconductor device
The utility model relates to an unmanned air vehicle technique field especially relates to an unmanned aerial vehicle undercarriage.
[ background of the invention ]
Unmanned aerial vehicle indicates to have power device, does not carry operating personnel's aircraft, and unmanned aerial vehicle is the aircraft that can VTOL, hover, fly backward and fly to the side, and the less flight performance of its volume is better, can replace the people to go to accomplish the task of relative danger, and unmanned aerial vehicle's the landing form of taking off mainly has: launch, boosting, run, VTOL, hit net recovery, parachute descending etc. unmanned aerial vehicle on the existing market, in order to solve the buffering problem when descending, often sets up the spring in the support frame, but, the spring produces fatigue easily and influences the elastic force, in addition, the spring length is too long can influence the stability of structure, if influence the elastic force again for too short.
[ Utility model ] content
The utility model aims to solve the technical problem related to in the background art.
The technical scheme of the utility model as follows: the utility model provides an unmanned aerial vehicle undercarriage, the main part is the unmanned aerial vehicle chassis, the rotation axis is installed respectively on four summits of unmanned aerial vehicle chassis, rotation axis centre of a circle position is opened there is the round hole, the rotation axis winds round hole axial rotation, the great one end of rotation axis side one end joint support frame cross sectional area, the telescopic structure of support frame for can changing length, two sections butt joint positions internally mounted of support frame have the cushion ball, the less one end fixed mounting of support frame cross sectional area has titanium alloy hemisphere supporting legs.
As an improvement of the utility model, the buffer ball is a hollow inflatable rubber ball.
As an improvement of the utility model, the holding tank has been seted up to two sections junctions of support frame inside, the cushion ball accept in the holding tank.
As an improvement of the utility model, each it is at least three to hold in the holding tank buffering ball.
As an improvement of the utility model, the rubber ball is made of butadiene rubber.
Compared with the prior art, the utility model provides a pair of unmanned aerial vehicle undercarriage has following advantage: the buffer ball is adopted for buffering, so that mechanical fatigue is not easy to generate, the buffer force is stable, and the replacement is convenient; adopt titanium alloy hemisphere support frame, when guaranteeing sufficient structural strength, have lighter weight, reduce unmanned aerial vehicle's heavy burden.
