Title:
ANTI-VIBRATION DEVICE FOR UNMANNED AIRCRAFT
Document Type and Number:
WIPO Patent Application WO/2019/198393
Kind Code:
A1
Abstract:
This anti-vibration device for an unmanned aircraft is configured by an anti-vibration rubber being interposed between the airframe body and legs of the unmanned aircraft which are connected to each other, the anti-vibration rubber being fixed to the airframe body and the legs by means of fixing members. As one example of the anti-vibration rubber, an anti-vibration mount having a rubber elastic body interposed between a plate provided on the airframe body and plates provided on legs may be used. As another example, an anti-vibration bushing having a cylindrical rubber elastic body interposed between an outer cylinder and an inner cylinder may be used. As yet another example, an anti-vibration grommet having an annular mounting groove provided in the outer peripheral surface of a cylindrical rubber elastic body may be used. The fixing members position the anti-vibration rubber in, for example, a direction which receives a vertical load component by shear deformation and a horizontal load component by compression/tensile deformation.
