IMU damping device and unmanned aerial vehicle

The IMU damping device comprises a base, a damping assembly and an IMU assembly, the damping assembly comprises a connecting structure and an elastic arm, the elastic arm comprises a first connecting section, a second connecting section and a third connecting section, and the third connecting section is obliquely connected between the first connecting section and the second connecting section. When the IMU damping device is vibrated, the vibration brought to the IMU assembly firstly passes through the damping assembly, and the three-section type elastic arm structure formed by the first connecting section, the second connecting section and the third connecting section in the damping assembly has flexible deformation capacity, so that the buffering effect of the damping assembly can be ensured; the data monitoring accuracy of the IMU assembly is improved. 本实用新型提供了一种IMU减震装置和无人机，IMU减震装置包括底座、减震组件和IMU组件，减震组件包括连接结构和弹性臂，所述弹性臂包括第一连接段、第二连接段和倾斜连接在所述第一连接段和所述第二连接段之间的第三连接段。IMU减震装置在受到震动时，带给IMU组件的震动会首先经过减震组件，而减震组件中由第一连接段、第二
