Aircraft foot frame driving mechanism

Abstract

The invention discloses an aircraft foot frame driving mechanism. The foot frame driving mechanism comprises a steering engine and a gear set, wherein the steering engine is fixed to a bone frame of an aircraft through a foot frame mounting seat, and the gear set is mounted between a crankshaft of the steering engine and a rotary shaft of an aircraft foot frame, so as to control the extension and recovery of the foot frame under the action of the steering engine. According to the aircraft foot frame driving mechanism, since the position of the rotary shaft is kept unchanged when the steering engine stops rotating, and the extension angle and the recovery angle of the foot frame are determined. According to the aircraft foot frame driving mechanism, the accurate control over the extension and the recovery of the foot frame are achieved through the transmission of the steering engine and the gear set, and when the steering engine stops rotating, the aircraft foot frame is ensured to be affected by the steering engine under the action of certain external force without being forced to extend or recover.

Description

Technical field [0001] The invention relates to aircraft manufacturing technology, in particular to a tripod drive mechanism of an aircraft. Background technique [0002] At present, aircraft or unmanned aerial vehicles have been more and more widely used in social life, for close observation of places that are difficult for people to reach, or high-altitude aerial photography, thereby providing convenience for observation and shooting. [0003] Existing aircraft are often composed of the aircraft fuselage and the arms extending from the aircraft fuselage to the outside. Motors and propellers are installed at the outer ends of the arms to drive the aircraft to fly. The lower part of the aircraft is also provided with a tripod. To facilitate the landing of the aircraft. [0004] However, in the existing aircraft, the extended arms and tripods are all fixedly connected to the fuselage. After use, the larger arm span makes the aircraft require higher storage space, and at the same time...

Problems solved by technology

[0004] However, in the existing aircraft, the stretched arms and tripods are all fixedly connected to the fuselage. After use, the large arm span makes the aircraft have higher requirements for storage space. The weight of the aircraft itself needs to be considered, and the structure of each part of the aircraft is relatively simple. Therefore, the large arm span also leads to the danger of easy damage caused by improper storage
