机械部分包括一由不透光材质的制成的编码转盘和一外盖2，该编码转盘5为中心具有转轴4的中空圆环盖5，编码转盘的外环壁开设有至少一个光通孔6光路径开关；
光电部分由光对管3和底板1构成，光对管3为相对而设的由发光元件301和光敏元件302构成，PCB底板1上开设有安装编码转盘的通孔9，发光元件301和光敏元件302采用贴片技术电连接固定在PCB底板1上并覆设防水膜；PCB底板1的底部设有电性排线或电性排针10；
将编码转盘5的转轴4对准PCB底板1的通孔9，使编码转盘5扣合于底板1上且编码转盘5的外环壁位于发光元件301和光敏元件302之间；再将外盖2扣合在编码转盘上固定于PCB底板1上。光电部分与机械部分独立设置，光对管与PCB底板电连接，编码转盘的转轴驱动连接有电机，电机驱动转轴使编码转盘旋转，编码转盘的外环壁旋转，当光对管的光路径遇到光通孔时，形成光通路路径，反之形成开路状态，光敏元件与发光元件之间的光路径形成循环开路、通路 的状态。
机械部分还包括一弹力件8，所述弹力件8为两端具有插脚的横梁结构，弹力件8的横梁中部弯曲为一段圆弧形的凸起端801；所述编码转盘5上设置有一圈段落环7，所述段落环7的表面为均布的圆弧凹凸701；所述PCB底板1上设置有两插孔；将弹力件的插脚插入插孔中固定，弹力件的凸起端801朝向段落环的外表面圆弧凹凸701并使凸起端801与圆弧凹凸701相接触。段落环与编码转盘对齐形成一个整体，节省了整个机械部分的空间，整体厚度变薄，同时弹力件也布置在PCB底板上，结构紧凑，不用增加多余部件。
外盖2的外周底部设置有至少一个卡勾12，PCB底板1外周开设有与卡勾12相对应的底板缺口101，将卡勾12与底板缺口101一一对应卡合在一起，使外盖2扣合在PCB底板1上。这种扣合方式方便定位，组装稳定不容易发生偏位。
编码器的光电部分还包括有发光LED模块11，发光LED模块11采用贴片技术电连接固定在PCB底板1上；其中编码转盘5、弹力件8和光对管3都位于外盖2之内，发光LED模块11位于在外盖2之外。
本申请的工作原理如下：当编码转盘转动时，圆环盖的外环壁上的光通孔跟着发生移动，使光敏元件与发光元件之间的光信号发生变化；同时圆环盖上的段落环随着转动，段落环上的圆弧凹凸与一旁弹力件的凸起端接触发生阻尼振动，当圆弧凹凸的凹陷处与凸起端接触时，阻尼最小，当圆弧凹凸的凸起处与凸起端接触时，阻尼最大。
本申请的编码转盘为中心具有转轴的不透光材质的中空圆环盖，利用中空圆环盖外环壁上的光通孔与圆环盖内外的光对管实现光通路的变化，识别灵敏、快捷，段落环与弹力件振动实现操作时的段落感；圆环盖和段落环采用一体化设计，生产方便，结构紧凑，节省了底板与外盖之间的空间，外盖还能有效防水防尘，外盖与底板之间组装拆卸方便。
以上所述，仅为本发明的较佳实施例，并不用以限制本发明，凡是依据本发明的技术实质对以上实施例所作的任何细微修改、等同替换和改进，均应包含在本发明技术方案的保护范围之内。
