【附图说明】
图1为本发明的实施例提供的陀螺仪的结构分解图;
图2为本发明的实施例提供的陀螺仪的整体结构示意图;
图3为图2中A-A的剖视图;
图4为本发明的实施例提供的陀螺仪的俯视图。
【具体实施方式】
下面结合附图和实施方式对本发明作进一步说明。
参考图1和图2,本发明一较佳实施例提供一种陀螺仪100,包括基板10、环状支撑板20及架设于环状支撑板20一侧的振动件30,振动件30包括环状部31和多个沿环状部31周向间隔环绕设置于环状部31外周的弹性连接部32,每个弹性连接部32的一端都与环状部31的外周壁连接、另 一端都延伸固定于环状支撑板20上,弹性连接部32设有偶数个,且任意相邻两个弹性连接部32都相互对称设置。弹性连接部32与环状支撑板20连接处设置有用于电性连接的引脚324,环状支撑板20由二氧化硅制成,振动件30由金属制成。引脚324处于持续通电的状态,从而振动件30也处于导电状态。振动件30架设于环状支撑板20上,在正常状态下,电流正常,无波动;若环状部31受到外界的压力作用,弹性连接部32会发生转动,从而会导致电流发生变化,通过电流的变化,陀螺仪100就能检测到相应的角速度变化。本发明实施例提供的陀螺仪100,结构简易,设置多个弹性连接部32既保持了转动的弹性又可以抑制不必要的振动;且任意相邻两个弹性连接部32都相互对称设置,使得抗非必要振动性更强。
参考图1和图3,优选地,环状支撑板20的外部轮廓形状为矩形,环状支撑板20具有中空内孔21,中空内孔21的中心轴与环状部31的中心轴重合。振动件30架设于环状支撑板20上,将环状支撑板20正对振动件30的部位设置成通孔,可避免振动件30发生振动时,弹性连接部32与环状支撑板20发生碰撞,以至于影响检测结果。
优选地,中空内孔21为正多边形孔,偶数个弹性连接部32的数量为正多边形孔边数的两倍,正多边形孔的每一条边都对应设有两个对称设置的弹性连接部32。将弹性连接部32对称设置,可以使得抗非必要振动性更强。
优选地,在本发明提供的实施例中,正多边形孔的边数为偶数。作为本实施例的一较佳实施方案,正多边形孔的边数为八,弹性连接部32的数量为十六。当然了,正多边形孔的边数可以为其他任意的偶数,确保相邻弹性连接部32是对称设置的,使得弹性连接部32排布均匀且连接稳定,从而使得抗非必要振动性更强即可。
参考图1和图4,优选地,每个弹性连接部32都包括一端与环状部31外周壁连接的第一杆体321、一端与环状支撑板20连接的第二杆体322和弯折连接于第一杆体321与第二杆体322之间的第三杆体323,各相邻的两个弹性连接部32以两第一杆体321间隔平行的方式相邻设置或者以两第 二杆体322间隔平行的方式相邻设置。第一杆体321、第二杆体322及第三杆体323连接形成的整体大致呈Z字型。正多边形孔的每一个内角都对应设有两个间隔平行设置的第一杆体321。相邻的两个弹性连接部32之间保持有距离,可以避免弹性连接部32在振动时相互间发生碰撞,从而提高检测结果的准确可靠性。
优选地,环状部31呈圆环状。其结构简单、便于制造成型,且便于偶数个弹性连接部32的对称连接。当然了,环状部31也可以为其他正多边形状。
优选地,陀螺仪100包括基板10,环状支撑板20之背对振动件30的一侧层叠固定于基板10上。优选地,基板10为矩形板。此处,增设基板10,可增加陀螺仪100整体的强度。
本发明实施例中,振动件30架设于环状支撑板20上,当受到外界的作用力使得振动件30发生转动时,电流发生变化,进而检测到角速度;本发明实施例提供的陀螺仪100结构简易,设置多个弹性连接部32既保持了转动的弹性又可以抑制不必要的振动;且任意相邻两个弹性连接部32都相互对称设置,使得抗非必要振动性更强。
以上所述的仅是本发明的实施方式,在此应当指出,对于本领域的普通技术人员来说,在不脱离本发明创造构思的前提下,还可以做出改进,但这些均属于本发明的保护范围。
