Abstract
An inertial measurement device includes: a shell, sensor components and vibration damping components installed in the shell. The sensor components include an integrated circuit board, an inertial sensor connected to the integrated circuit board, and a barometric sensor connected to the integrated circuit board. The vibration damping components include a first cushion, a first weighting piece, a second weighting piece and a second cushion which are connected successively. An accommodating cavity for accommodating the integrated circuit board is formed between the first weighting piece and the second weighting piece. The first weighting piece includes a holding cavity for accommodating the inertial sensor and a pressure chamber accommodating the barometric sensor and communicating with the exterior of the inertial measurement device.
