Description

高精度可变度数电子眼镜 技术领域
本发明涉及一款可供使用者用电子方式自主调节度数的高精度眼镜。
背景技术
申请号为CN201380078659.2的专利提出了一种屈光不正治疗眼镜。这种眼镜由可以用电子方式控制度数的变化，其主要特征是利用电子时钟，周期性地自动改变眼镜的度数。
美国3305294号专利描述了两块构造特殊的透镜做垂直轴向的平行移动时，会造成轴向的屈光度变化。
美国7980690号专利根据3305294号专利设计出了一款眼镜，可以用一种机械方式让眼镜度数发生变化。在此基础上可以联想到使用步进电机控制镜片进行移动，从而实现度数变化，但是并不能直接得出步进电机与镜片的具体连接方式。
以上发明也没有提出让使用者用电子方式自主调节度数的功能。
技术问题
本发明要解决的技术问题是怎样将眼镜度数的变化以高精度方式具体实现，并让使用者用电子方式自主调节度数。
问题的解决方案
技术解决方案
本发明针对现有技术不足，提出一种可以精确变化度数的电子眼镜。
本发明的提供技术方案包括9个主要组成部分：(1)眼镜架(2)镜片(3)鼻托(4)眼镜腿(5)镜片与步进电机的连接辅助件(6)步进电机(7)步进电机控制电路(8)太阳能充电模块(9)使用者终端
为精确控制度数的变化，本方案中设计了步进电机与镜片的连接方式。步进电机与镜片通过一个内部含有螺纹孔的辅助部件(简称为“内嵌螺纹套”)进行连接。
内嵌螺纹套与镜片采取紧密连接方式，步进电机的输出转轴与内螺纹套采取螺纹传动方式，步进电机的转轴旋转时，利用机械原理推动内螺纹套和镜片一起移动。
由于步进电机可以精确控制转轴旋转的角度，从而推动螺纹套和镜片以极高的精度移动，眼镜的度数精确度可以达到0.01D，D为屈光度的单位。附图1是3个单独的零件，附图2是组合后的装配体。
使用者可以通过使用者终端(如智能手机等)通过无线或有线方式与步进电机控制电路相连，发出度数变化指令，从而完成度数变化。
鼻托可以上下移动，以适应不同人的需要，装配方式见附图3。
发明的有益效果
有益效果
1、眼镜的度数可以高精确度变化。
2、使用者可以自主控制度数。
3、鼻托可以适应不同人需要。
