Abstract
A MEMS gyroscope includes an anchor point unit, a sensing unit elastically connected with the anchor point unit, and a driving unit elastically connected with the anchor point unit and the sensing unit. The anchor point unit includes four corner anchor point structures arranged at four corners of the MEMS gyroscope and four central anchor points. The sensing unit includes four first mass blocks elastically connected with the corner anchor point structures and the central anchor points to form avoiding spaces, four second mass blocks arranged within the avoiding spaces, and four decoupling mass blocks. The driving unit includes four driving pieces respectively connected with outer sides of the second mass blocks. The MEMS gyroscope realizes independent detection of angular velocities of three axes and realizes differential detection and balance of vibration moment, which immune to influence of acceleration shock and quadrature error and improves detection accuracy.
