Retractable landing gear of unmanned aircraft

Abstract

The invention discloses a retractable landing gear of an unmanned aircraft. The retractable landing gear comprises a base, a steering engine, a first rod member, a supporting frame and a fixed seat, wherein the steering engine is fixed in the hollow base, a steering engine output shaft penetrating through the side of the base is fixedly connected to a drive end of the first rod member, a linking end of the first rod member is hinged to the supporting frame, the supporting frame is hinged to the middle part of the fixed seat, and the upper part of the fixed seat is hinged to the base. The retractable landing gear of the unmanned aircraft has two stable states: supporting of the fixed seat and retraction of the fixed seat. In the aerial photo process, the fixed seat of a landing rack can be retracted, the retracted fixed seat does not hinder a photograph camera, and the 360-degree all-around smooth photographing of the camera can be guaranteed; meanwhile, the retracted fixed seat can alleviate the affection of lateral wind for the landing rack, and the stable photographing of the unmanned aircraft can be facilitated.

Description

technical field [0001] The invention relates to the technical field of control of unmanned aerial vehicles, in particular to retractable landing gear for unmanned aerial vehicles. Background technique [0002] Existing unmanned aerial vehicles have a wide range of applications, not only for aerial photography, but also for monitoring fires, earthquakes, floods, etc. in professional fields. In order to realize aerial shooting, imaging devices such as cameras and video cameras can be installed on the multi-axis unmanned aerial vehicle, and other equipment can also be installed. The aircraft is often unstable during flight. In order to provide a stable shooting platform for the imaging device, more and more gimbals with stabilization functions are applied to multi-axis aircraft. However, this cannot completely prevent the unmanned aerial vehicle from being affected by other factors, resulting in unstable shooting of the aerial vehicle. [0003] Because the existing unmanned a...

However, this cannot completely prevent the unmanned aerial vehicle from being affected by other factors, resulting in the unsteady shooting of the aerial vehicle

[0003] Because the existing unmanned aerial vehicle uses fixed landing gear, and the fixed landing gear is easily affected by the crosswind when the wind is strong or at high altitude, which will seriously affect the stability of the unmanned aerial vehicle and cause great damage to the shooting. big trouble

[0004] In addition, when the stabilized gimbal rotates 360 degrees in the horizontal plane, the fixed landing gear often blocks the camera's line of sight, thus affecting aerial shooting
