附图说明
下面将结合附图及实施例对本发明作进一步说明,附图中:
图1是本发明电压调节装置的原理框图;
图2是本发明的电压调节装置另一实施方式的原理框图;
图3是图1的电压调节装置一个具体实施例的原理框图;
图4是图1的电压调节装置另一个具体实施例的原理框图;
图5是本发明电压调节装置第一实施例的结构示意图。
具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白,以下结合附图及实施例,对本发明进行进一步详细说明。应当理解,此处所描述的具体实施例仅仅用以解释本发明,并不用于限定本发明。
如图1所示,本发明的电压调节装置包括用于对笔记本电脑供电的笔记本电源适配器4,用于检测实际供电电压信号并根据预设电压计算所需电压,将所需电压发送给控制模块的电压信号处理模块5、用于根据所述所需电压生成控制信号的控制模块3和用于接收控制模块3的控制信号根据所需电压调节笔记本电源适配器4输出的供电电压的电压调节模块6。
笔记本电源适配器4通过OUTPUT+、OUTPUT-两个触点与笔记本电脑连接并对其进行供电,电压信号处理模块5根据预设电压与实际供电电压电流信号进行分析,其得到的所需电压,控制单元3接收到所需电压后,控制电压调节模块6进行调节供电电压,使适配器供电电压符合当前设备的工作电压。此外,图2示出的是一种只用于USB电压调节的电压调节装置。
此外,电压调节装置还包括用于手动控制电压调节模块6的手动调节模块7,手动调节模块7连接电压调节模块6,可以根据用户的经验习惯进行手动调节,使用起来更加方便。
本发明的电压调节装置还可以设置各种传感器8,这些传感器8与控制模块3相连,用于检测环境参数。可以理解的是,控制模块中预存有不同的调节的方案,这些调节方案与不同的环境参数向对应,比如,在区别白天与黑夜时即可将黑夜调节为省电模式,从而可以达到节电的效果。这些传感器可以是声控设备、光控设备、湿控设备,温控设备或任意两种或两种以上的组合,当然传感器也可以是其他可能的形式,并不限于以上提出的几种形式。
如图3所示,本发明的电压调节装置还包括USB适配器1和USB电压检测调节模块2,图5示出了该装置第一实施例的结构示意图,图中示出部分交流电源线,交流电源线与插头相连。其中,USB适配器1用于通过USB端口对电子设备供电,USB电压检测调节模块2用于检测USB端口的数据线正负极两端D+、D-之间的电压信号。由于USB端口一般包括USB电源VCC、数据线正极D+、数据线负极D-和接地GND在内的四个触点,此处的数据线正负极D+、D-两端之间的电压信号实际上是说这两个触点的电压值。控制模块3还用于判断电压信号是否符合电子设备的预设值并在不符合时指示USB电压检测调节模块2调节USB适配器1的供电电压或USB适配器的D+,D-两端的电压。本发明中的电子设备是指除了笔记本电脑外的可通过USB充电的平板电脑、手机等设备。
本装置还可以与具有ID身份的设备实现通讯功能,如图4所示,USB电压检测调节模块2包括设备ID识别单元201和USB电压调节单元202,设备ID识别单元201用于识别电子设备的ID代码并发送给控制模块3,USB电压调节单元202用于根据控制模块3的反馈信息调节USB适配器的供电电压。
可以理解的是,控制模块3应该预存有对应不同电子设备的调节方案,每个调节方案与相应电子设备的ID代码相对应。控制模块3在接收电子设备的ID代码后,优先根据电子设备的ID代码自动生成调节方案并将调节方案作为反馈信息发送给USB电压调节单元202。此外,上述调节方案还可以用于对笔记本电脑供电电压的调节,控制电压指示电压调节模块6根据调节方案对笔记本电源适配器4的供电电压进行调节,使其符合上述的预设电压。
虽然本发明是通过具体实施例进行说明的,本领域技术人员应当明白,在不脱离本发明范围的情况下,还可以对本发明进行各种变换及等同替代。另外,针对特定情形或材料,可以对本发明做各种修改,而不脱离本发明的范围。因此,本发明不局限于所公开的具体实施例,而应当包括落入本发明权利要求范围内的全部实施方式。
