Abstract
The invention relates to a damping undercarriage of a quadrotor, and belongs to an unmanned plane undercarriage with damping function. According to the damping undercarriage, a support is utilized for fixing a motor, the motor drives two belts to make transmission along different directions through a group of gears, and further drives the undercarriage to deploy and retract through the belts. The undercarriage is hinged with a fastening connector, and the upper end of the undercarriage is connected with the fastening connector via an extension spring. The undercarriage comprises an upper arm and a lower arm which are in connection via s crossbeam and are respectively inside provided with springs. The advantages comprise that the damping undercarriage is novel in structure, can be deployed and retracted according to flight states, reduces air resistance in the flight process, and substantially improve the stability of an unmanned plane. In landing process, the undercarriage is telescopic, the shock loading coefficient is reduced, and the safety of the unmanned plane is improved.
Description
Technical field
The invention belongs to one and have shock-absorbing function unmanned plane alighting gear, be specifically related to the alighting gear of freedom retractable and Telescopic, be mainly used in reducing in flight course slowing down in resistance and decline process in the face of the impulsive force of fuselage.
Background technology
Four rotor wing unmanned aerial vehicles are a kind of Small and micro-satellite, and because flexibility ratio is high, stability is strong, and simple to operate, the advantages such as cost is lower gain great popularity.But, four current rotor wing unmanned aerial vehicles, aloft during flight because its fixing alighting gear makes resistance increase, in addition, when landing faced by fuselage can cause very strong rigid shock, in this regard, four rotor wing unmanned aerial vehicles still face very large challenge.
Summary of the invention
The invention provides a kind of damping alighting gear of four-axle aircraft, the problem of rigid shock during to solve the flight resistance of current Small and micro-satellite existence and to land.
The technical scheme that the present invention takes is: motor is contained in for connecting in the support of unmanned plane, gear one is connected with the output shaft of motor, gear two is connected with holder pivots by axle, gear one and gear two are connected with a joggle, profile of tooth power wheel one is fixedly connected on the output shaft between gear one and motor, profile of tooth power wheel two is fixedly connected between gear and support, profile of tooth power wheel one is connected with odontoid belt one, profile of tooth power wheel two is connected with odontoid belt two, odontoid belt one, odontoid belt two opposite side is connected with the profile of tooth power wheel of two alighting gear upper arm respectively, wherein alighting gear upper arm and the device chain connection that is connected, alighting gear upper arm is connected extension spring with being connected between device, it is fixing after alighting gear upper arm and alighting gear underarm enter the chute of alighting gear upper arm by crossbeam-rotating, and the built-in spring of difference, the attaching parts be connected with fuselage is connected with the device that is connected.
Alighting gear upper arm one of the present invention is connected extension spring one with being connected between device one.
Advantage of the present invention is novel structure, and alighting gear can carry out folding and unfolding according to state of flight, decreases the resistance of air in flight course, substantially increases the stability of unmanned plane.In descent, alighting gear is scalable, reduces impact load coefficient, improves the safety of unmanned plane.
