Abstract

The invention relates to the field of aerial vehicles, and in particular relates to a shock-absorbing device and an unmanned aerial vehicle. The shock-absorbing device comprises a first connecting piece, at least one second connecting piece and at least one shock-absorbing part, wherein each second connecting piece is connected with the first connecting piece through the at least one shock-absorbing part; each shock-absorbing part comprises a shock-absorbing part body and at least one throttling valve; each shock-absorbing part body comprises a flexible cavity provided with at least one opening; each throttling valve is correspondingly arranged at one opening of each flexible cavity and is provided with at least one throttling hole for communicating the inner part of each flexible cavity with an external environment. The shock-absorbing parts in the shock-absorbing device can be used for simultaneously isolating low-frequency vibration and high-frequency vibration, so two shock-absorbing parts for respectively isolating the low-frequency vibration and the high-frequency vibration are not needed to be arranged in the shock-absorbing device, and further the use amount of the shock-absorbing parts in the shock-absorbing device is reduced; the high-frequency vibration and the low-frequency vibration are simultaneously isolated under the condition that the shock-absorbing device is enabled to be smaller in size.

Description

technical field [0001] The invention relates to the field of aircraft, in particular to a shock absorbing device and an unmanned aircraft. Background technique [0002] Unmanned aerial vehicles are currently widely used in military or civilian fields, with functions such as surveillance, reconnaissance, and aerial photography. The shooting function of the unmanned aerial vehicle generally needs to be realized by mounting the gimbal. Since the unmanned aerial vehicle will vibrate during the flight, the vibration will affect the stability of the shooting picture or cause the shooting picture to shake after the vibration is transmitted to the gimbal. In order to reduce the gimbal For vibrations received during shooting, a shock absorbing device is generally provided between the gimbal and the fuselage of the unmanned aerial vehicle. [0003] Figure 1a with Figure 1b Shown is a schematic diagram of the exploded structure of two common pan-tilt damping devices, Figure 1a Sho...
