Spherical mechanical interface and head-mounted device using same

The invention relates to a spherical mechanical interface and a head-mounted device using the same. The spherical mechanical interface is configured for coupling the eyewear arm with the frame. The spherical mechanical interface includes a surface having a generally spherical bend and at least two apertures extending through the surface. The surface is configured to be secured to a portion of the eyeglass arm by a fastener received along a first axis through a first of the at least two apertures. The surface is configured to be secured to the portion of the eyeglass arm by another fastener received along a second axis through a second one of the at least two apertures, the second axis being different from the first axis. 本发明涉及球形机械接口以及使用该球形机械接口的头戴式设备。该球形机械接口被配置成用于将眼镜臂与框架耦接。该球形机械接口包括表面，该表面具有大体上球形的弯曲部和延伸穿过该表面的至少两个孔。该表面被配置成通过紧固件固定到该眼镜臂的部分，该紧固件沿第一轴线穿过该至少两个孔中的第一孔被接纳。该表面被配置成通过另一紧固件固定到该眼镜臂的该部分，该另一紧固件沿第二轴线穿过该至少两个孔中的第二孔被接纳，该第二轴线与该第一轴线不同。
