Title:
UNMANNED AERIAL VEHICLE FOLDING MECHANISM
Document Type and Number:
WIPO Patent Application WO/2021/196135
Kind Code:
A1
Abstract:
An unmanned aerial vehicle folding mechanism, comprising a fuselage (1), an even number of flying arms (2) evenly distributed at the edge of the fuselage, a camera (3) fixed to the bottom of the fuselage, an even number of folding assemblies evenly installed in the fuselage, and supporting legs (17) in transmission connection with the folding assemblies. The supporting legs (17) correspond to the flying arms (2) in quantity and position; when an unmanned aerial vehicle flies, the supporting legs (17) are controlled by the folding assemblies to contract upwards, so that the bottoms of the folded supporting legs (17) are flush with the bottom of the camera (3); and when the unmanned aerial vehicle needs to stay on a supporting surface, the supporting legs (17) extend downwards under the control of the folding assemblies to achieve the supporting function so as to support the fuselage (1) and the flying arms (2). The supporting legs (17) having the folding function are installed under the fuselage (1), and therefore, control over the height in the flight process is not affected, and the supporting legs can land in advance in the landing process, protecting the fuselage.
