Retractable supporting frame for unmanned aerial vehicle

Abstract

The invention discloses a retractable supporting frame for an unmanned aerial vehicle. The retractable supporting frame comprises cross rods, connecting rods, a supporting frame body and a cooling fan; and the two cross rods are arranged in parallel, the two connecting rods are welded between the two cross rods in parallel, the bottoms of the cross rods are connected with a bottom plate through springs, the bottom plate is of an air bag structure, four telescopic rods are arranged on the cross rods, the tops of the telescopic rods are fixed to the supporting frame body, telescopic switches arearranged on the telescopic rods, a groove is formed in the upper portion of the supporting frame body, a buffer layer is arranged at the bottom of the groove, a plurality of buffer springs are fixedin the buffer layer, openings are formed in the supporting frame body and the buffer layer, the cooling fan is arranged at the bottom of the supporting frame body, a fan switch is arranged on one sideof the supporting frame body, a storage battery groove is further formed in the supporting frame body, and a storage battery is embedded in the storage battery groove. According to the retractable supporting frame, impact force generated during landing of the unmanned aerial vehicle can be effectively reduced, the unmanned aerial vehicle can be protected, the supporting frame can be folded conveniently when the unmanned aerial vehicle flies, and the flying resistance of the unmanned aerial vehicle is reduced.

Description

technical field [0001] The invention relates to the technical field of drones, in particular to a retractable support frame for drones. Background technique [0002] According to the application field, UAV can be divided into military and civilian. In terms of military use, UAVs are divided into reconnaissance aircraft and target aircraft. In terms of civilian use, drones + industry applications are the real rigid needs of drones; currently, they are used in aerial photography, agriculture, plant protection, selfies, express delivery, disaster rescue, wildlife observation, infectious disease monitoring, surveying and mapping, news reports, and power inspections. Applications in fields such as disaster relief, film and television shooting, and romance manufacturing have greatly expanded the use of drones themselves. Developed countries are also actively expanding industry applications and developing drone technology. [0003] The support frame of the existing UAV is inconve...

AI Technical Summary

Problems solved by technology

[0003] The support frame of the existing UAV is inconvenient to use, because the support frame is long, it is easy to make the flight of the UAV inconvenient, and it is easy to damage the UAV when flying in a small space, and the larger support frame is easy to increase the airflow resistance during flight , it is not convenient for the UAV to fly stably. In addition, the UAV will have a strong impact when it lands. The traditional UAV support frame has poor shock absorption effect.
