[0003] However, the current unmanned aerial vehicle that can carry objects places the materials on the bracket at the bottom of the drone when carrying the materials. The current material placement rack is directly welded to the bottom of the drone. Folding, when the drone is not in use, it will take up a large space, which is not conducive to the retraction of the drone

The invention discloses an adjustable folding and unfolding mechanism for an unmanned aerial vehicle. The adjustable folding and unfolding mechanism comprises an unmanned aerial vehicle body, a folding and unfolding mechanism body, a bottom plate, fixing bases, first supports, second support, rotating shafts, a fixing mechanism, a limiting mechanism, clamping columns, clamping rings, tension springs, limiting pieces and containing mechanisms. The adjustable folding and unfolding mechanism has the beneficial effects that the two limiting pieces are wrenched towards the interiors of the clampingrings, the two limiting pieces of arc-shaped structures are stored in the clamping rings, the tension springs contract, then notches in the side faces of the two clamping rings are opened, then the clamping columns at the ends of the two second supports are moved out of the clamping rings, at the moment, the two second supports and the two first supports can rotate around the rotating shafts, thelimiting pieces are loosened to seal the clamping rings, then the two first supports and the two second supports are further pushed in the bottom face direction of the bottom plate, and therefore, the opening range of the first supports and the second supports is reduced, the first supports and the second supports are stored, and the space occupied area of the whole structure is reduced.
Description
technical field [0001] The invention relates to a retractable mechanism, in particular to an adjustable retractable mechanism for unmanned aerial vehicles, belonging to the technical field of unmanned aerial vehicles. Background technique [0002] Unmanned aircraft is referred to as "unmanned aerial vehicle", and the English abbreviation is "UAV". It is an unmanned aircraft operated by radio remote control equipment and its own program control device. UAV is actually a general term for unmanned aerial vehicles. From a technical point of view, it can be divided into: unmanned fixed-wing aircraft, unmanned vertical take-off and landing aircraft, unmanned airship, unmanned helicopter, unmanned multi-rotor aircraft, unmanned Paraplane etc. [0003] However, the current unmanned aerial vehicle that can carry objects places the materials on the bracket at the bottom of the drone when carrying the materials. The current material placement rack is directly welded to the bottom of ...
