The invention relates to a quasi-zero stiffness six-degree-of-freedom damping device for an unmanned aerial vehicle holder, which comprises a supporting device and a damping device, and the supporting device comprises a connecting seat, a load seat and a mounting seat; the external equipment is mounted on the mounting seat; a three-axis rotating mechanism is arranged between the load seat and the mounting seat; the vibration damping device comprises an upper vibration damping unit and a lower vibration damping unit; the upper vibration reduction unit and the lower vibration reduction unit are each composed of an upper end face, a lower end face and an elastic bent rod arranged between the upper end face and the lower end face. And the cross section of the elastic bent rod is a crescent cross section. Through the improvement, the quasi-zero-rigidity six-degree-of-freedom vibration reduction device can quickly and adaptively reduce external vibration when the unmanned aerial vehicle is interfered by vibration, has a good vibration reduction effect on movement and rotation in the directions of x, y and z rectangular coordinate axes, can keep the stability of externally-loaded equipment, and can be applied to the unmanned aerial vehicle. The influence of external vibration on the unmanned aerial vehicle is reduced, so that the working performance and flight stability of the unmanned aerial vehicle are improved.

    本发明涉及一种用于无人机云台的准零刚度六自由度减振装置,包括支撑装置和减振装置,所述支撑装置包括连接座、负载座和安装座;外载设备安装在安装座上;负载座与安装座之间设有三轴旋转机构;所述减振装置包括上减振单元和下减振单元;上减振单元和下减振单元均由上端面、下端面以及设置在上端面和下端面之间的弹性弯杆构成;所述弹性弯杆的横截面为月牙形截面。通过上述改进,使得本发明的准零刚度六自由度减振装置可在无人机受振动干扰时迅速自适应地对外部振动进行减振,在沿x、y、z三个直角坐标轴方向的移动和转动均具有良好的减振效果,可保持外载设备的稳定性,减小外部振动对无人机的影响,从而提高无人机的工作性能和飞行稳定性。
