GYROSCOPE
Document Type and Number:
WIPO Patent Application WO/2020/206712
Kind Code:
A1
Abstract:
Provided is a gyroscope (100), comprising an annular support plate (20) and a vibrating member (30), wherein the vibrating member (30) includes an annular portion (31) and a plurality of elastic connecting portions (32) arranged at intervals along the circumferential direction of the annular portion (31), each elastic connecting portion (32) includes arc-shaped rods (321) arranged at intervals on the outer circumference of the annular portion (31), a first rod (322) connected between the arc-shaped rod (321) and the outer peripheral wall of the annular portion (31), and a second rod (323) extending from the arc-shaped rod (321) and fixed on the annular support plate (20), each arc-shaped rod (321) is distributed at intervals along a circle which is concentric with the annular portion (31). The vibrating member (30) of the gyroscope (100) is erected on the annular support plate (20), when the vibrating member (30) is rotated by external force, the current changes and the angular velocity is detected; providing a plurality of elastic connecting portions (32) not only maintains the elasticity of rotation but also suppresses unnecessary vibration; and the elastic connecting portions (32) are provided with arc-shaped rods (321) concentric with the annular portion (31), such that the structure of the entire vibrating member (30) has no acute angle, and it is easier to manufacture while maintaining elasticity and resistance to unnecessary vibration performance.
