Embodiment Construction

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] like figure 1 , figure 2 and image 3 As shown, a gyroscope according to an embodiment of the present invention includes a fixed frame 1 and a vibration unit accommodated in the fixed frame 1. The vibration unit includes a mass block 3 and a connection frame 2 surrounding the mass block 3, so The gyroscope also includes a first connecting member 4 connecting the vibration unit and the fixed frame 1 and a second connecting member 5 connecting the mass block 3 and the connecting frame 2, so that the vibration unit is connected with the first connection. The component 4 rotates with the central axis, and the mass block 3 rotates with the second connecting component 5 as the central axis. The extending direction of the first connecting member 4 is perpendicular to the extending direction of the second connecting member 5 . Preferably, opposite sid...

Abstract

The present invention provides a gyroscope, the gyroscope includes a fixed frame and a vibration unit accommodated in the fixed frame, the vibration unit includes a mass block and a connection frame surrounding the mass block, and the gyroscope also It includes a first connecting piece connecting the vibration unit and the fixed frame and a second connecting piece connecting the mass block and the connecting frame, so that the vibration unit rotates with the first connecting piece as the central axis, and the mass The block rotates with the second connecting piece as the central axis. The structure of the present invention can make the rotation angle of the gyroscope to be large during rotation detection, so that the vibration amplitude is strong, and finally the signal output is strong.

Description

【Technical field】 [0001] The present invention relates to the technical field of a rotation-sensitive device using a vibrating component, such as a Coriolis force-based vibration angular velocity sensor (G01C19 / 56), and relates to a gyroscope. 【Background technique】 [0002] MEMS gyroscope is a micro-electromechanical gyroscope. MEMS (Micro-Electro-Mechanical Systems) refers to a complete micro-electro-mechanical system that integrates mechanical elements, micro-sensors, micro-actuators, signal processing and control circuits, interface circuits, communications and power supplies. . [0003] In addition, the existing gyroscope structure is not high enough in rotation detection accuracy, therefore, it is necessary to provide a gyroscope capable of high-precision rotation measurement. [Content of the invention] [0004] The purpose of the present invention is to provide a gyroscope, which can improve the measurement of the rotation accuracy of the gyroscope. [0005] One o...
