Connecting structure, rack and aircraft

Abstract

A connection structure includes: an elastic body (100) for connecting to one of an arm (20) and a fuselage (30); the rotating shaft assembly (200) is connected with the elastic body (100) and used forbeing connected with the other one of the vehicle arm (20) and the vehicle body (30), so that the vehicle arm (20) rotates relative to the vehicle body (30) to form at least one stroke interval; wherein the stroke interval is provided with a first position, a second position and a third position located between the first position and the second position, and the rotating shaft assembly (200) is further used for abutting against and compressing the elastic body (100) in the process that the vehicle arm (20) gets close to the third position. The elastic body (100) is also used for enabling thevehicle arm (20) to automatically rotate to the first position or the second position when the vehicle arm (20) exceeds the third position; the invention also relates to a frame and an aircraft.

Description

technical field [0001] The present application relates to the technical field of aircraft vibration-damping connection, in particular, to a connection structure, a frame and an aircraft. Background technique [0002] For aircraft such as drones, the power system is the main source of fuselage vibration, and the vibration of the fuselage will cause many problems, such as IMU overrange, aliasing, structural fatigue, etc. [0003] In the prior art, the vibration impact of the fuselage is reduced by adding a vibration reduction system between the fuselage and the arm. However, in many cases, aircraft such as drones have volume requirements, and the addition of a vibration reduction system will undoubtedly increase the The size of the whole machine, and the need to realize both the rotation function and the self-locking function between the existing fuselage and the arm, which makes it more difficult to set up the vibration reduction system, and the vibration reduction effect is ...
