Portable telescopic unmanned aerial vehicle

Abstract

The invention discloses a portable telescopic unmanned aerial vehicle. The technical problem that the volume of an existing telescopic unmanned aerial vehicle cannot be sufficiently shrunk is solved. The unmanned aerial vehicle comprises a vehicle body; vehicle arms are arranged on the side edges of the vehicle body, telescopic supports are connected between the vehicle body and the vehicle arms, and power portions are arranged at the two ends of the vehicle arms correspondingly; power portions comprise motors and propellers, wherein the motors and the propellers are assembled together, the orientation of the propellers can be rotatably adjusted through the power portions on the vehicle arms, and the telescopic supports are connected with the power portions through connecting rods; the vehicle arms are pulled outwards, the telescopic supports are expanded and deformed, and the power portions are driven by the connecting rods to rotate to adjust the orientation of the propellers to be upward; and the vehicle arms are pushed inwards, the telescopic supports are shrunk and deformed, and the power portions are driven by the connecting rods to rotate to adjust the orientation of the propellers to be horizontal. According to the portable telescopic unmanned aerial vehicle, the vehicle arms are each arranged to be of a structure capable of integrally moving relative to the vehicle body, and the motors and the propellers are driven to rotate while the vehicle arms are shrunk, so that the volume of the unmanned aerial vehicle is sufficiently reduced.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle, in particular to a portable telescopic unmanned aerial vehicle. Background technique [0002] In recent years, related technologies and applications of multi-axis unmanned aerial vehicles (referred to as unmanned aerial vehicles) have developed vigorously. As disclosed, the fuselage 100 includes a machine body 151, and several machine arms 153 are arranged around the machine body 151, and a power part is arranged at the end of the machine arm 153, and the power part includes a motor and a propeller. The machine arm 153 is non-retractable, and the position of the power unit is non-adjustable, so the volume of this type of drone cannot be reduced and is inconvenient to carry. [0003] For non-retractable arms, the design has been improved in the prior art, such as disclosed in the Chinese utility model patent "A Foldable Rotor-type UAV" (CN103979107U, published on August 13, 2014). Four rotor arms 2 ...

AI Technical Summary

Problems solved by technology

The UAV of this structure realizes the folding function of the machine arm, which can effectively reduce the volume of the UAV, but after folding, the upper end of the rotor arm 2 protrudes from the main body 1, and the length (also can be regarded as the height) of the UAV remains the same. Longer, limited shrinkage volume, less than ideal

The four rotor arms 2 need to be unfolded and retracted one by one, and the operation process
