Unmanned aerial vehicle with multi-vehicle-arm synchronous folding mechanism

Abstract

The invention relates to the field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle with a multi-vehicle-arm synchronous folding mechanism. The unmanned aerial vehicle comprises a base, multiple vehicle arms, clamping assemblies and folding assemblies, wherein the base is in a flat board shape and is provided with multiple rotary shafts extending parallel to the base; the multiple vehicle arms are connected with the rotary shafts in the manner that the vehicle arms can rotate around the corresponding rotary shafts, and the vehicle arms can be in the unfolded state to be parallel to the base and the folded state to be perpendicular to the base; the clamping assemblies are used for keeping the multiple vehicle arms in the unfolded state; and the folding assemblies are used for synchronously releasing the clamping state of the clamping assemblies, so that the multiple vehicle arms are converted into the folded state synchronously from the unfolded state. The multi-vehicle-arm synchronous folding mechanism is composed of the clamping assemblies and the folding assemblies. By the adoption of the above technical scheme, the unmanned aerial vehicle capable of achieving synchronous folding of the multiple vehicle arms is provided, so that the size of the unmanned aerial vehicle is easy to change, and in the vehicle arm folding process, operation is easy, and use is convenient.

Description

technical field [0001] The present invention relates to the field of unmanned aerial vehicles; more particularly, the present invention relates to the unmanned aerial vehicle (especially refers to small and medium-sized unmanned aerial vehicle) that has multi-machine arm synchronous folding mechanism. Background technique [0002] At present, the arms of small and medium-sized UAVs usually have two structural forms: fixed type and foldable type. The body size of the UAV with fixed arms is not easy to change, which affects the portability of the UAV. UAVs with foldable arms usually use a single arm folding mechanism. When using this single arm folding mechanism, each arm needs to be folded successively. Like this, under the situation that machine arm is many, have the defective that operation is loaded down with trivial details, inconvenient to use. Contents of the invention [0003] The present invention is made based on the defects of the above-mentioned prior art, and...
