请参阅图1至图3,本申请还提供一种三轴陀螺仪,包括隔离减振装置、数据处理单元和连接器1,第一测量单元4和第二测量单元7分别靠近并平行壳体3相邻的两个侧壁所述第三测量单元8与壳体3的底板平行;数据处理单元平行设置于壳体3的底板上,且在第一测量单元4和第三测量单元8之间,底板上设有用于限位数据处理单元的限位结构;连接器1贯穿设置于壳体3与第二测量单元7相对的一个侧壁上;第一测量单元4、第二测量单元7和第三测量单元8分别借助连接线与数据处理单元相连,数据处理单元借助连接线与连接器1相连。其中第一测量单元4、第二测量单元7和第三测量单元8分别对应设有六种颜色的连接触点14,按颜色及编号与数据处理单元对应的连接,连接器1与数据处理单元对应连接。
本申请提供的三轴陀螺仪的有益效果在于:由于三个方向的测量单元分别借助减振结构安装在壳体3内,因此能够减少在同一个壳体3内的三个轴向的测量单元相互干扰,消除共振,保证器件的精度和灵敏性,提高测量的准确性。
其中,具体的,三个陀螺测量单元通过减振垫及相应的胶固定在图1中壳体3的三个位置上,其中的两个与底板垂直,一个与底板平行,通过连接线与中间的数字处理单元10相连接,数字处理单元10为图1中L形状的平板,数字处理单元10通过连接线与连接器1,连接器1为陀螺仪的输出口,然后通过密封胶封上盖板2,并用螺钉紧固。
以上所述仅为本申请的较佳实施例而已,并不用以限制本申请,凡在本申请的精神和原则之内所作的任何修改、等同替换和改进等,均应包含在本申请的保护范围之内。
