Foldable wing structure

Abstract

The invention discloses a wing folding structure which comprises a wing platform, a rotating assembly, a wing assembly, a driving assembly and a limiting assembly, the rotating assembly comprises a first rotating shaft and a second rotating shaft which are rotationally connected with the wing platform, and the wing assembly comprises a left wing and a right wing; the left wing is fixedly connected with the first rotating shaft, and the right wing is fixedly connected with the second rotating shaft; the wing assembly has a folded state and an unfolded state; the limiting assembly is arranged on the wing platform and movably connected with the rotating assembly, so that the rotating assembly is limited to be fixed when the limiting assembly is effective, and the wing assembly is in the folded state; the driving assembly is in transmission connection with the rotating assembly so as to drive the rotating assembly to rotate when the limiting assembly fails, and then the wing assembly is converted into the unfolded state from the folded state. On the premise that the folding size is small, the functions of eliminating the height difference after the wings are unfolded and having the dihedral angle are achieved, and an aircraft has better aerodynamic performance while being convenient to store and transport.

Description

technical field [0001] The invention relates to the technical field of drones, in particular to a foldable wing structure. Background technique [0002] Unmanned aerial vehicles have developed into an irreplaceable equipment, performing tasks such as long-endurance reconnaissance, area surveillance, search and positioning, and fire guidance. In the storage, transportation and use stages of the UAV, the UAV is required to have a small folding space. [0003] With the development of science and technology, the requirements of fluid mechanics on the aerodynamic shape of aircraft are more and more stringent. In order to maintain a good aerodynamic shape, the folding method of the partially foldable UAV is hindered. The specific deflection angle of the wing surface prevents the wing from being well folded into the wing. The wing with a drop also has a great interference with aerodynamics, which affects the stability and endurance of the aircraft, while the complex mechanism has...

Problems solved by technology

Because there is a height difference when the wings are folded up and down, the wings also have a height difference when they are unfolded. Such a height difference will affect the aerodynamic performance of the aircraft.
