    • Laser scanning module employing a scan mirror and magnet rotor subassembly supported by a stationary stator structure. The scan mirror and magnet rotor subassembly includes: a silicone frame having a pair of silicone torsional hinges (i.e. posts) aligned along a scan axis and a supported by a pair of support elements associated with the stator structure, to support the scan mirror and magnet rotor subassembly. When the scan mirror and magnet rotor subassembly is rotated about its scan axis, by forces generated by an electromagnetic coil structure acting on the permanent magnet mounted on silicone frame, the silicone torsional hinges are elastically distorted and generate linear restoring forces which return the rotor subassembly back to its home position about the scan axis.
    • 激光扫描模块采用由固定定子结构支撑的扫描镜和磁体转子子组件。 扫描镜和磁体转子子组件包括:硅胶框架,其具有沿着扫描轴对准的一对硅胶扭转铰链(即柱),并且由与定子结构相关联的一对支撑元件支撑,以支撑扫描镜和磁体 转子组件。 当扫描镜和磁体转子子组件围绕其扫描轴旋转时,通过作用在安装在硅胶框架上的永磁体上的电磁线圈结构产生的力,硅胶扭转铰链弹性变形并产生线性恢复力,使回转子组件 回到其关于扫描轴的原始位置。
