Title:
FOLDABLE FRAME AND UNMANNED AERIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/041876
Kind Code:
A1
Abstract:
Provided are a foldable frame and an unmanned aerial vehicle. The frame comprises: a body; a connection arm (1) connected to the body and capable of rotating between an unfolded position and a folded position; and a rotating member (3) and a fixing member (4), wherein the rotating member is mounted on the connection arm (1), and the fixing member (4) is mounted on the body; one of the rotary member (3) and the fixing member (4) is a magnet capable of generating a magnetic field, and the other is a magnet or a ferromagnetic material capable of being attracted by a magnet; and when the connection arm is rotated, under the interaction of the rotating member (3) and the fixing member (4), the connection arm (1) can rotate to the unfolded or folded position and be kept in the position. The frame can be applied to the technical field of unmanned aerial vehicles. The connection arm can rotate and drive a rotor or a pan-tilt platform to be unfolded or folded, and after the rotor is folded, the transportation of the unmanned aerial vehicle is convenient, and the rotor can be prevented from colliding and being damaged. After the pan-tilt platform is unfolded, the interference of a landing gear for a camera device can be avoided, thereby realizing the implementation of a panoramic camera without interference. Under the action of a magnetic field force of the rotating member and the fixing member, the connection arm enables the rotor or the pan-tilt platform to be kept in the unfolded or folded position.
