Damping device and unmanned aerial vehicle

Abstract

This invention proposes a vibration damping device. The device includes a first fixed plate, a plurality of first columns, a second fixed plate, a plurality of first damping elements, and a plurality of second damping elements. The plurality of first columns are fixed to the first fixed plate. The second fixed plate has a plurality of through holes and a plurality of extensions, wherein the extensions are disposed on the second fixed plate and correspond to at least a portion of the through holes. The first columns pass through the extensions and at least a portion of the through holes. The plurality of first damping elements are disposed between the first and second fixed plates. The plurality of second damping elements are disposed between the extensions and the first columns. This invention also provides a drone equipped with this vibration damping device. The vibration damping device and drone proposed in this invention can eliminate lateral vibrations.
