Abstract

The invention provides a vehicle frame central piece of a multi-rotor unmanned aerial vehicle. The vehicle frame central piece comprises an upper piece body and a lower piece body which are each of an integrated structure. The upper piece body comprises an upper half part of a hollow polygonal central disc and a plurality of pipe clamp upper half parts outwards extending from the outer edge of the central disc upper half part. The lower piece body comprises a lower half part, corresponding to the central disc upper half part, of the hollow polygonal central disc and a plurality of pipe clamp lower half parts which are arranged corresponding to the pipe clamp upper half parts and outwards extend from the outer edges of the central disc lower half part. Disc openings of the central disc upper half part and the central disc lower half part are connected to form the central disc. The pipe clamp upper half parts and the corresponding pipe clamp lower half parts are connected to form pipe clamps. The vehicle frame central piece of the multi-rotor unmanned aerial vehicle can be manufactured from continuous fiber reinforced plastic, a mold pressing or RTM process is adopted, and product quality stability is good.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a frame centerpiece of a multi-rotor unmanned aerial vehicle. Background technique [0002] A multi-rotor UAV consists of multiple cantilever-supported motors and propellers, connected by a central plate. There are several modes in the prior art: the overall structure of injection molded parts, the integral molding structure of continuous fiber reinforced plastics, or the combined structure of plates and rods. The structure of injection molded parts is suitable for very large batch production, and small and light-loaded UAVs; the production efficiency of continuous fiber-reinforced plastic integral molding structure is slow, and the product quality is difficult to repeat; the plate-rod combination structure is complex to assemble, difficult to maintain, and low in structural reliability. Contents of the invention [0003] In view of the above-mentioned defects or defici...
