技术领域
本发明涉及一种太阳眼镜，特别是一种低功耗自动感光太阳眼镜。
背景技术
为防止外界强光刺激造成人眼伤害，配戴太阳眼镜是人们常采用的保护措施之一。目前市场上的太阳眼镜，通常是全黑的墨镜或者是带有手动翻盖功能的墨镜，佩戴这种太阳眼镜，从有太阳或光线较强的地方到无太阳或光线不强的地方时，都需要将太阳眼镜移开或将翻盖掀起才有较好视野，如果环境频繁交替，频繁操作眼镜会增加不必要的麻烦。
现有技术中的自动感光太阳眼镜，可以针对光照环境变化自动调节镜片，其使用液晶做镜片，通过改变加在液晶镜片上的电压改变镜片的光透过率。目前的自动感光太阳眼镜耗电量大，输出电压频率较高，一般采用USB充电模式，需要在镜架上加装USB接口，影响美观，每次使用前都需要充满电，且续航时间较短，使用不方便，无法满足随时使用的要求。
发明内容
为解决上述问题，本发明的目的在于提供一种低功耗的自动感光太阳眼镜。
本发明解决其问题所采用的技术方案是：
一种低功耗自动感光太阳眼镜，包括眼镜架以及设在眼镜架上的两个液晶镜片、供电模块、用于感应环境光度的光敏器、用于调节液晶镜片光暗状态的微处理器和用于提高输出电压的高频充放电升压电路，所述光敏器与所述微处理器的控制输入端连接，所述供电模块与所述微处理器的电源端相连，所述微处理器包括升压控制端，所述升压控制端与高频充放电升压电路输入端连接，还包括用于切换液晶镜片驱动高低电压的低频切换驱动电路，所述高频充放电升压电路的输出端与低频切换驱动电路连接，所述低频切换驱动电路的输出端分别与两个液晶镜片连接。
进一步，所述低频切换驱动电路内置于微处理器中，微处理器还包括振荡电源电路和降频电路，所述振荡电源电路通过升压控制端为高频充放电升压电路提供高频充电信号，所述振荡电源电路通过降频电路向低频切换驱动电路提供低频切换信号。依靠振荡电源电路，可以提高充电频率，从而大幅提升供电电压；降频电路可以大幅降低供电电压的频率，减少驱动电压高低电平的翻转频率，减少眼镜的耗电量。
进一步，所述微处理器还包括用于为微处理器内部供电的电源驱动电路，所述供电模块通过电源端与供电模块连接并提供直流供电，所述电源驱动电路包括脉冲电源电路，所述脉冲电源电路包括脉冲电源输出端，所述脉冲电源电路将来自供电模块的直流电转换为脉冲供电信号从脉冲电源输出端输出，所述脉冲电源输出端与振荡电源电路连接。所述脉冲电源产生用于驱动微处理器内部器件工作的脉冲供电信号，所述脉冲供电信号与振荡电源电路连接提供用于起振的脉冲供电信号，所述振荡电源电路利用该脉冲供电信号产生高频充电信号供高频充放电升压电路工作。

进一步，所述微处理器还包括用于检测光敏器电压值的电压检测电路，所述电压检测电路的输入端与光敏器连接，电压检测电路的输出端与低频切换驱动电路连接。所述电压检测电路检测光敏器输出的电压值，当该电压值大于设定的阀值时，认为当前眼镜处于光线较强的状态，这时电压检测电路向低频切换驱动电路发送开关信号，使低频切换驱动电路工作，若电压值小于设定的阀值时，电压检测电路不输出信号，低频切换驱动电路停止输出，液晶镜片恢复正常状态。
进一步，所述电压检测电路通过一延时电路与低频切换驱动电路连接，还包括外置于微处理器的延时控制电容，所述延时控制电容与延时电路连接。通过设置延时电路和用于控制延时时间的延时控制电容，使低频切换驱动电路延时输出，避免瞬间的强光导致液晶镜片频繁降低透光率，让使用者体验感更好。

参照图1至图4，本发明的一种低功耗自动感光太阳眼镜, 包括眼镜架10以及设在眼镜架上的两个液晶镜片50、供电模块20、用于感应环境光度的光敏器30、用于调节液晶镜片光暗状态的微处理器40和用于提高输出电压的高频充放电升压电路1，所述光敏器30与所述微处理器40的控制输入端SEI连接，所述供电模块20与所述微处理器40的电源端VDD相连，所述微处理器40包括升压控制端DC+/DC-，所述升压控制端DC+/DC-与高频充放电升压电路1输入端连接，还包括用于切换液晶镜片驱动高低电压的低频切换驱动电路2，所述高频充放电升压电路1的输出端与低频切换驱动电路2的输入端VLCD连接，所述低频切换驱动电路2的输出端LCDA+/LCDA-分别与两个液晶镜片50连接。通过设置在眼镜上的光敏器30智能感应光线的变化来自动触发开关，使镜片发生明暗变化，免去用户手动操作，方便使用。感光电路通过高频充放电升压电路1，大幅提高输入的供电电压，只需连接小型低压电池即可实现工作，同时依靠低频切换驱动电路2，大幅降低液晶镜片50驱动电压的频率，从而有效降低眼镜功耗，实现省电功能，延长电池及眼镜的使用寿命。
参照图1、图5所示，所述低频切换驱动电路2内置于微处理器40中，微处理器40内还设置有振荡电源电路3和降频电路4，所述振荡电源电路3通过升压控制端为高频充放电升压电路1提供高频充电信号，所述振荡电源电路3通过降频电路4向低频切换驱动电路2提供低频切换信号。依靠振荡电源电路3，可以提高充电频率，从而大幅提升供电电压；降频电路4可以大幅降低供电电压的频率，减少驱动电压高低电平的翻转频率，减少眼镜的耗电量。
由于本发明功耗十分低，所述供电模块20只需使用一节1.55伏纽扣电池供电，所述高频充放电升压电路1输出电压VLCD为电池电压的4倍即6.2伏。纽扣电池电压小，成本低，通过升压电路可以大幅提高驱动电压，实现节省电池寿命的效果。
所述振荡电源电路3为高频充放电升压电路1提供的高频充电信号频率为185赫兹。所述降频电路4向低频切换驱动电路2提供的低频切换信号是频率为1/90赫兹的方波信号。1/90赫兹的频率使电平每90秒翻转一次，耗电量少。
具体地，参照图1、图6所示，所述微处理器40还包括用于为微处理器40内部各器件提供供电的电源驱动电路5，所述电源驱动电路5包括一脉冲电源电路，所脉冲电源电路用于产生脉冲供电信号，所述脉冲电源电路通过电源端VDD与纽扣电池连接获取1.55V的直流电压并转换为脉冲供电信号输出，脉冲电源电路提供两路脉冲供电信号：脉冲电压信号PP和脉冲电压信号Pn，所述脉冲电压信号PP和脉冲电压信号Pn输出至振荡电源电路3中为振荡电源电路3提供起振脉冲供电信号，另外脉冲电压信号PP还作为电压检测电路6和延时电路7的电流源。
参照图1、图5和图7所示，所述微处理器40还包括用于检测光敏器30电压值的电压检测电路6，所述电压检测电路6的输入端与光敏器30连接，电压检测电路6的输出端与低频切换驱动电路连接。所述光敏器30包括两个光敏二极管和一个固定电阻，所述光敏二极管与固定电阻并联连接。采用两个光敏二极管可以提高感光灵敏度，与电阻连接后可以直接将光信号转换成电压信号通过微处理器40的SEI引脚输出到电压检测电路6中， 参照图7所示，脉冲电压信号PP为电压检测电路6提供脉冲驱动电源，当光敏器30的电压值大于420mV时,导通门电路，所述电压检测电路6的输出端sens输出控制信号，当光敏器30的电压值小于375mV时，电压检测电路6的输出端sens停止控制信号的输出，所述电压检测电路6还设置有用于检测是否有控制信号输出的TSENS端口。
本发明中，光敏器30无需额外进行供电即可产生足够的检测电压。而对于一些光敏器30需要额外进行供电才能正常工作，参照图6所示，所述脉冲电源电路还包括用于为光敏器提供供电电压的偏置电流输出端IBIAS，所述偏置电流输出端IBIAS与光敏器的供电端口连接，这样无需再配置另外的供电电路，即可通过微处理器40进行供电，有助于简化电路。若所采用的光敏器30无需额外供电，则悬空所述偏置电流输出端IBIAS即可。
参照图1、图8所示，微处理器40还包括一延时电路7，所述电压检测电路6的输出端sens与延时电路7的输入端连接，另外脉冲电压信号PP作为延时电路7的电流源，所述延时电路7的输出端on与低频切换驱动电路2的输入端连接，向低频切换驱动电路2输出液晶眼镜开关的信号。所述延时电路7的延时时间可以控制，延时电路7包括用于控制延时时间的CDO端口，所述CDO端口连接有延时控制电容60，所述延时控制电容60延迟为每纳法拉18毫秒的模拟延迟。为了测试延时电路7输出是否正常，所述延时电路7还包括用于进行测试的TON测试端口，所述TON测试端口与延时电路7的输出端on并联。
参照图9所示，为本发明的振荡电源电路，为一振荡器，所述脉冲电压信号PP和脉冲电压信号Pn输入至振荡电源电路的输入端为其提供起振脉冲供电信号，通过振荡电源电路将脉冲电压信号PP和脉冲电压信号Pn转换为高频充电信号，所述高频充电信号分别从升压控制端DC+和DC-输出，其输出的高频充电信号为185赫兹。另外，所述振荡电源电路还并联输出185赫兹的脉冲电压信号到降频电路4。所述振荡电源电路还包括用于属于测试信号的TST测试端。
参照图10所示，所述降频电路4由多路锁存器串联组成，具体本实施例中采用了14个锁存器组成链式分频器，通过该链式分频器，将185赫兹的脉冲电压信号降频到1/90赫兹的方波信号输出到低频切换驱动电路2。
参照图5所示，所述高频充放电升压电路1包括由两个二极管对管单元D2A和D2B组成的整流电路和与二极管对管单元D2A和D2B连接的充放电电容C4、C5和C8，其中电容C4分别连接升压控制端DC+和D2A公共端，电容C5分别连接升压控制端DC+和D2B公共端，所述D2A的一端连接VDD，另一端D2B连接及与通过电容C8与升压控制端DC-连接，D2B的另一端连接VSS，这样，当升压控制端DC+和DC-输出185赫兹的高频充电信号时，通过整流电路和充放电电容输出6.2V的输出电压VLCD，由于该高频充放电升压电路1的存在，只需采用电压及体积较小的纽扣电池即可满足整个电路的供电需求。
参照图11所示，所述低频切换驱动电路2包括两个对称的模拟开关电路和一个逻辑开关电路21，所述高频充放电升压电路1的输出端通过微处理器40的VLCD端连接到低频切换驱动电路2，并分别通过第一模拟开关电路22和第二模拟开关电路23连接至低频切换驱动电路2的输出端LCD1和LCD2，其中LCD1通过微处理器40的LCDA+连接液晶眼镜，LCD2通过微处理器40的LCDA-连接液晶眼镜。所述第一模拟开关电路22和第二模拟开关电路23受逻辑开关电路21控制，所述逻辑开关电路21控制包括两个控制输出端，一个用于控制第一模拟开关电路22，另一个用于控制第二模拟开关电路23，其中两个控制端的控制信号相反，因此LCDA+和LCDA-能交替输出的电压控制信号。
所述逻辑开关电路的控制端包括来自延时电路7的输出端on和来自降频电路的1/90赫兹的方波信号，受到该两个信号的控制，逻辑开关电路在接收到来自输出端on的开启信号后，受到1/90赫兹的方波信号控制，使LCDA+和LCDA-以1/90赫兹的频率翻转输出，进而使液晶镜片50在90秒翻转一次，大幅降低液晶镜片驱动电压的频率，从而有效降低眼镜功耗，实现省电功能，同时延长电池及眼镜的使用寿命。
参照图2、3所示，所述光敏器30和微处理器40设置在眼镜架10的鼻托上，所述供电模块20设置在眼镜架10的鼻托或眼镜架10的两根支腿上。这一设置最大化减少了电路元件对眼镜外观的影响，提高太阳眼镜的美观程度。
参照图4所示，所述液晶镜片包括上玻璃基板6和下玻璃基板7，上玻璃基板6、下玻璃基板7的电极分别连接至所述微处理器的低频切换驱动电路2的输出端。
以上所述，只是本发明的较佳实施例而已，本发明并不局限于上述实施方式，只要其以相同的手段达到本发明的技术效果，都应属于本发明的保护范围。
