Unmanned aerial vehicle undercarriage folding and unfolding system

Abstract

The invention discloses an unmanned aerial vehicle undercarriage folding and unfolding system which comprises a fixed frame, the inner side wall of the fixed frame is fixedly connected with a first-stage electric telescopic rod, the end face of the movable end of the first-stage electric telescopic rod is fixedly connected with a rack, and the outer side face of the rack is slidably connected with the inner wall of the fixed frame; one side of the lower surface of the fixed frame is provided with a first-stage round hole and a second-stage round hole. According to the unmanned aerial vehicle undercarriage folding and unfolding system, through the arrangement of the buffer structure, the unmanned aerial vehicle undercarriage folding and unfolding system has the effect of prolonging the service life, so that the situation of damage during landing is avoided, and the purpose of improving the damping effect is achieved; through the cooperated arrangement of the transmission structure, the rack and the first-stage gear, in the using process, the lifting rod can be indirectly driven to move up and down through the first-stage electric telescopic rod, so that the effects of convenience and rapidness are achieved, and the purpose of conveniently folding and unfolding the undercarriage is achieved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle landing gear retractable system. Background technique [0002] Unmanned aerial vehicle, referred to as unmanned aerial vehicle (UAV); UAV is a new concept weapon equipment in rapid development. Its advantages have emerged in many local wars since the Vietnam War. UAVs have been used in tasks such as battlefield reconnaissance, surveillance, precise target positioning / indication, electronic countermeasures, communication relay, and combating ground "time-sensitive" targets. Very good performance. However, with the expansion of UAV applications, UAV flight platforms are developing in the direction of high altitude, high speed, long endurance, and stealth. [0003] At present, the development of domestic drones is also particularly rapid, and the specifications cover various levels from large to micro drones. However, for micro and small...
