背景技术
鼠标，是计算机的一种外接输入设备，也是计算机显示系统纵横坐标定位的指示器，因形似老鼠而得名。其标准的称呼应该是“鼠标器”，鼠标的使用是为了使计算机的操作更加简便快捷，来代替键盘那繁琐的指令，采用光轮的鼠标具有红外光光源，具有极高的分辨率以及刷新频率，操作时具有灵活和精准的优点。

在本发明的描述中，需要理解的是，术语“开孔”、“上”、“下”、“厚度”、“顶”、“中”、“长度”、“内”、“四周”等指示方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的组件或元件必须具有特定的方位，以特定的方位构造和操作，因此不能理解为对本发明的限制。
请参阅图1-图10，本发明实施例提供一种技术方案：磁阻尼极速光学轮，包括PCBA板1和设置在PCBA板1上的中键2，PCBA板1的表面通过PCB板3安装有支架4，支架4的内部设置有与PCBA板1电连接的光传感部件；
支架4的内部通过金属轴5设置有磁性内轴6，磁性内轴6的表面均匀阵列设置有第一磁齿7，磁性内轴6的表面套接有磁性外轴8，金属轴5的表面与磁性内轴6的内侧壁活动连接，磁性外轴8的内部对应第一磁齿7设置有第二磁齿9，磁性外轴8的表面设置有轴套10。
磁性内轴6和磁性外轴8均具有磁场，磁性内轴6上的第一磁齿7向着磁性外轴8的方向凸起，磁性外轴8内侧壁上的第二磁齿9向着磁性内轴6的方向凸起，第一磁齿7和第二磁齿9均均匀阵列设置，自然状态的一一对应，在轴套10带动磁性外轴8转动的过程中，当第一磁齿7与第二磁齿9对应时，两者之间的吸力最强，随着第一磁齿7与第二磁齿9错开，吸力逐渐减弱，之后吸力再次增强，从而可以在使用时，产生段落感，由于 第一磁齿7和第二磁齿9之间没有机械接触，完全依靠之间的吸力来实现段落感，从而具有机械编码器没有的顺滑，不会过于机械。
具体的，金属轴5的一端与支架4的内侧壁插接，金属轴5与磁性内轴6为注塑一体，磁性内轴6的一侧一体成形设置有卡块11，支架4的表面开设有卡槽12，卡块11的表面与卡槽12的内侧壁活动连接。
本实施方案中，金属轴5与磁性内轴6为注塑一体，金属轴5可以与支架4内侧壁上的圆槽对接，磁性内轴6上的卡块11设置有斜面，在安装时，只需要使卡块11的斜面与支架4的表面挤压，在斜面的作用，支架4发生弹性形变，之后卡块11进入到卡槽12的内部，从而可以实现对磁性内轴6的固定，防止其转动。
具体的，轴套10的内侧壁对称固定连接有限位块13，磁性外轴8的表面对称设置有两组限位部，限位部包括两个限位片14，每组限位部的两个限位片14分别与两个限位块13活动连接，磁性外轴8与轴套10之间设置有限位胶圈15，轴套10的表面套接有皮圈16。
本实施方案中，在安装轴套10与磁性外轴8时，金属轴5与磁性内轴6为注塑一体，金属轴5与磁性外轴8之间活动连接，可以转动，之后将磁性外轴8插入到轴套10的内部，使相邻的两个限位片14之间的间隙与限位块13的位置对应，可以将磁性外轴8插入到轴套10的内部，并通过限位块13和限位片14对磁性外轴8进行限位，之后将限位胶圈15安装在磁性外轴8与轴套10之间，从而可以对磁性外轴8进行限位，防止脱落。
具体的，限位胶圈15的表面内侧壁与磁性外轴8的表面连接，限位胶圈15的外侧壁与轴套10的内侧壁连接，限位胶圈15的表面开设有槽口17，槽口17的内侧壁与限位块13的表面活动连接；
轴套10的表面开设有限位槽18，限位胶圈15的表面一体成形设置有固定部19，固定部19的表面与限位槽18的内侧壁活动连接。
本实施方案中，限位胶圈15上开设有与限位块13相适配的槽口17，限位胶圈15橡胶材质，可以填充在磁性外轴8与轴套10之间，具有较大的摩擦力，可以使轴套10与磁性外轴8之间的连接更加紧密，防止滑动，并且限位胶圈15上一体成形设置有固定部19，固定部19向外部隆起，可以伸入到轴套10上的限位槽18的内部，可以进一步增加限位胶圈15与轴套10之间的连接强度，从而可以防止脱落。
具体的，PCBA板1的上部电连接有左摆键20和右摆键21，支架4的表面一体成形设置有按压部22，按压部22设置在左摆键20和右摆键21之间。
本实施方案中，支架4上设置有环形槽，在鼠标外壳上设置有与环形槽对应的支撑件，图中未示出，通过外力使轴套10绕支撑件与环形槽的连接处转动可以实现支架4的摆动，从而可以通过支架4表面一体成形的按压部22挤压左摆键20或是右摆键21，使支架4向下运动，可以实现对中键2的挤压，从而可以实现多功能，使鼠标的功能更多，便于应用于不用的场。
具体的，光传感部件包括光学接收器23和光学发射器24，光学接收器23和光学发射器24均设置在支架4的内部，磁性外轴8的表面均匀阵列开设有通光孔25。
本实施方案中，光学发射器24发射光信号，可以被光学接收器23接收，光信号只有穿过磁性外轴8上的通光孔25时，才能被光学接收器23接收信号，通过检测到间隔的光信号可以判断轴套10转动，从而可以实现翻阅网页的效果。
使用时，手指触碰轴套10上的皮圈16，通过手指与皮圈16之间的摩擦力使轴套10转动，由于轴套10通过限位胶圈15与磁性外轴8连接，并且所述金属轴5与磁性内轴6为注塑一体，所以轴套10将会带动磁性外轴8同步转动，其上的通光孔25随着磁性外轴8转动，光传感部件中的光学发射器24发射光信号，穿过通光孔25可以传输到光学接收器23，从而可以根据间断判断轴套10的转动，第一磁齿7和第二磁齿9均设置为24个，转动一圈为24格，每格一个段落感，每转动一格对应一次光学信号，转动一圈发送24个信号，实现翻阅网页，通光孔25设置为12个，通过磁性外轴8的转动，可以使通光孔25转动，从而可以实现对光学接收器23与光学发射器24之间的光信号的通断，进而实现脉冲电压的输出，每滚动一格输出一个半波周期的脉冲，旋转一圈360°有24个半波脉冲，输出信号的列表如图9所示，滚动相位差t1、t2、t3、t4大于10ms，如图9所示；
磁性内轴6和磁性外轴8均具有磁性，磁性内轴6上的第一磁齿7向着磁性外轴8的方向凸起，磁性外轴8内侧壁上的第二磁齿9向着磁性内轴6的方向凸起，第一磁齿7和第二磁齿9均均匀阵列设置，自然状态的一一对应，在轴套10带动磁性外轴8转动的过程中，当第一磁齿7与第二磁齿9对应时，两者之间的吸力最强，随着第一磁齿7与第二磁齿9错开，吸力逐渐减弱，之后吸力再次增强，从而可以在使用时，产生段落感，第一磁齿7和第二磁齿9均设置为24个，转动一圈为24格，每格一个段落感，每转动一格对应一次光学信号，转动一圈发送24个信号，反应到电脑上即鼠标滚轮的翻页功能；
用力使轴套10快速转动时，外力将克服第一磁齿7与第二磁齿9之间的吸力，并且在惯性的作用下，轴套10会继续转动，并且第一磁齿7与第二磁齿9之间的吸力会辅助轴套10在失去外力后继续转动，使轴套10带动磁性外轴8持续转动，可以实现极速功能， 便于快速翻阅网页，最后在阻力的作用下以及第一磁齿7与第二磁齿9的吸力作用下，磁性外轴8停止转动，并且第一磁齿7与第二磁齿9一一对应；
支架4上设置有环形槽，在鼠标外壳上设置有与环形槽对应的支撑件图中未示出，通过外力使轴套10绕支撑件与环形槽的连接处转动可以实现支架4的摆动，从而可以通过支架4上的按压部22挤压左摆键20或是右摆键21，使支架4向下运动，可以实现对中键2的挤压，从而可以实现多功能，使鼠标的功能更多，便于应用于不用的场景。
综上，该磁阻尼极速光学轮，通过设置按压部22，轴套10，解决了机械编码器使用起来过于机械，不够顺滑，影响手感的问题。
