Title
(EN) Gyroscope
(ZH) 陀螺仪
Abstract
(EN) The utility model discloses a gyroscope which comprises a base, a first annular piece, a fixing piece, a second annular piece, a first connecting piece, a second connecting piece and an electrode assembly. The outer contour of the first annular piece is a positive 8N-angle star, and N is a positive integer; the fixing piece is arranged on the inner side of the first annular piece and is spaced from the first annular piece; the second annular piece is arranged on the outer side of the first annular piece, the second annular piece and the first annular piece are arranged at intervals, the outer contour of the second annular piece is a positive 8N-angle star, and N is an integer; the first connecting piece is connected with the first annular piece and the fixing piece; the second connecting piece is connected with the first annular piece and the second annular piece; the electrode assembly is used for forming a capacitor with at least one of the first annular piece and the second annular piece so as to drive the first annular piece and the second annular piece to vibrate in a first direction and a second direction which are perpendicular to each other, and detecting the vibration displacement of the first annular piece and the second annular piece along the direction that the included angle between the first annular piece and the first direction is 45 degrees or the included angle between the first annular piece and the second annular piece is 135 degrees.
(ZH) 本实用新型公开了陀螺仪,陀螺仪包括基底、第一环形件、固定件、第二环形件、第一连接件、第二连接件、电极组件;第一环形件的外轮廓为正8N角星,N为正整数;固定件设于第一环形件的内侧并与第一环形件间隔设置;第二环形件设于第一环形件的外侧并与第一环形件间隔设置,第二环形件的外轮廓为正8N角星,N为整数;第一连接件连接第一环形件和固定件;第二连接件连接第一环形件和第二环形件;电极组件,用于与第一环形件及第二环形件中的至少一个形成电容,以驱动第一环形件及第二环形件沿相互垂直的第一方向和第二方向振动,并检测第一环形件及所述第二环形件沿与所述第一方向的夹角呈45度方向或与所述第一方向的夹角呈135度方向的振动位移。
