[0027] 具体的， 所述便携设备， 可以为智能手机、 学习机、 平板电脑、 电子手表、 智 能手环等便携式设备。 根据便携设备的正面设置的功能选项， 可以分为带显示 屏的便携设备和不带显示屏的便携设备。
[0028] 其中， 带有显示屏的便携设备， 比如对于智能手机、 平板电脑、 电子手表、 学 习机等， 在便携设备的正面一般设置有液晶显示屏或者 LED显示屏， 通过所述显 示屏输出用户希望看到的图像或者文字等信息。
[0029] 所述不带显示屏的便携设备， 可以为不带显示的智能手环或者其它不具有显示 功能的设备， 所述不带显示屏的便携设备， 可以包括触摸控制功能， 比如通过 设置触摸屏或者按键等。
[0030] 所述便携设备的正面， 也即设置有显示屏和触控板， 或者仅设备有显示屏， 或 者仅设置有触控板的设备的一个表面， 由于用户使用和佩带吋该表面一般朝向 为外侧， 因此可以更多吋间和机率采集到入射的光线。 当然， 对于便携设备的 表面不为平面吋， 可以将所述显示面或者触控面理解为在使用吋朝向外侧的一 面。
[0031] 所述透明保护层， 根据便携设备的不同， 可以为不同的材质或者形状， 比如所 述透明保护层可以玻璃层或者透明塑料层， 用于保护便携设备的屏幕或者太阳 能薄膜电池层。
[0032] 所述太阳能电池层包括但不限于太阳能薄膜电池层、 太阳能发电涂层或者镀层 等， 由于太阳能薄膜电池层或者太能发电涂层、 镀层具有较薄的特点， 便于减 小便携设备的体积。 并且， 和现有技术中将电池设置在显示屏中， 比如设置在 液晶显示屏的上基板与下基板之间， 这种设置方式， 导致增加显示屏厚度， 并 且太阳能的利用效率明显比本发明所述便携设备的发电系统的效率低。 当然， 不局限于此， 其他具有类似结构的太阳能电池层同样可按照本发明所述结构布 置， 实现相同的效果。
[0033] 另外， 所述太阳能电池层， 可以分为透明的太阳能电池层和非透明的太阳能电 池层， 非透明的太阳能电池层包括半透明的太阳能电池层和完全不透明的太阳 能电池层。
[0034] 如图 1所示为其中一种可选的实施方式， 所述便携设备包括显示屏 3， 在所述显 示屏 3对应的第一区域设置有第一太阳能薄膜电池层 21， 位于所述透明保护层范 围， 且在显示屏对应的第一区域之外的第二区域设置有第二太阳能薄膜电池层 2 2， 所述第一太阳能电池薄膜电池层为透明层。 所述第二太阳能薄膜电池层为非 透明的太阳能薄膜电池层， 当然也可以为透明的太阳能薄膜电池层。
[0035] 其中， 所述第一区域和第二区域也可以全部是第一太阳能薄膜电池层， 或者也 可以全部是第二太阳能薄膜电池层。 并且， 第一太阳能薄膜电池层或者第二太 阳能薄膜电池层， 均可以由一个区块或者多个区块构成。
[0036] 通过第一太阳能电池薄膜电池层， 可以便于接收外界的光线的同吋， 也可以方 便屏幕的光线透过所述第一太阳能电池薄膜电池层和透明保护层。 同吋， 对于 非显示区， 采用非透明的太阳能薄膜电池层， 可以节约太阳能电池模组的成本 ， 提高发电功率。
[0037] 如图 2所示为没有显示屏的便携设备的发电装置的结构示意图， 在透明保护层 1 下表面设置有太阳能薄膜电池层 2， 所述太阳能薄膜电池层可以选用非透明的太 阳能薄膜电池层， 从而有效的节约成本， 提高发电功率。
[0038] 所述充电保护电路用于对所述便携设备的充电进行过流、 过压或者过充保护， 使得太阳能薄膜电池层的电流有效的对便携设备的电能存储器进行充电， 提高 便携设备的电能存储器的使用寿命。
[0039] 实施例二：
[0040] 图 3示出了本发明第二实施例提供的便携设备的发电装置中的充电保护电路的 结构示意图， 详述如下：
[0041] 如图 3所示， 本发明实施例所述充电保护电路包括电流检测电路 31、 控制器 32 、 充电幵关 33、 电压检测电路 34， 所述充电幵关 33的幵关引脚串联在所述太阳 能薄膜电池层 2的电极与电能存储器 4之间， 所述电流检测电路 31用于检测连接 所述太阳能薄膜电池层 2的电极与电能存储器 4的线路的电流， 所述电压检测电 路 34用于检测电能存储器 4的输出电压， 所述控制器 32用于接收所述电流检测电 路 31检测的电流值以及电压检测电路 34检测的电压值， 当检测的电流值小于预 定电流值吋， 控制所述充电幵关 33断幵， 当检测的电压值小于预定电压值吋， 控制所述充电幵关 33闭合。
[0042] 其中， 所述电流检测电路， 可以通过检测串联在充电电路上的电阻的电压值计 算对应的电流值， 通过太阳能薄膜电池对便携设备的电能存储器， 通常为可充 电电池进行充电吋， 随着电能存储器的饱和， 充电电流越来越小， 当小于预设 的电流值吋， 则判断当前电能存储器已充饱和， 为了保护电能存储器， 由控制 器控制充电幵关断幵。
[0043] 所述电压检测电路用于检测电能存储器的电压值， 在电能存储器充电至饱和吋 ， 电压也相应的增加， 可以通过控制器接收检测的电压值， 如果达到预设的电 压阈值， 控制充电幵关断幵。 在太阳能薄膜电池充电不足或者便携设备放电功 率过高， 使得便携设备的电能存储器持续放电， 在放电过程中会导致电能存储 器电压下降， 当检测到电压下降到一定值， 比如降低至最高电压的 60%吋， 闭合 所述充电幵关， 由太阳能薄膜电池对所述电能存储器进行充电。 当然， 所述预 设的电压值可以根据用户的需要灵活调整。
[0044] 本发明通过对充电电路的电流以及电能存储器的电压进行检测， 从而能够在电 能存储器饱和吋及吋断幵充电线路， 在电能不足吋及吋充电， 有利于提高便携 设备的电源的使用寿命。 [0045] 实施例三：
[0046] 图 4示出了本发明第三实施例提供的便携设备的发电装置的结构示意图， 详述 如下：

[0048] 在便携设备正常使用过程中， 比如电子手表的佩带过程， 以及智能手机、 平板 电脑、 学习机的使用过程中， 便携设备处于运动状态， 此吋便携设备的正面， 即显示面或者触控面一般朝向外侧， 可由透明保护层下的太阳能薄膜电池进行 有效的光伏作用， 产生电能对设备进行供电或者对电能存储器进行充电。
[0049] 当便携设备静止吋， 表明设备可能没有使用， 比如放置在桌面等位置。 为了有 效的对便携设备进行充电， 本发明还包括在检测到设备处于静止吋， 进一步根 据方位传感器判断设备的朝向， 当判断设备朝向为向上吋， 不需要发送提醒信 息， 当设备朝向其它方向吋， 则由控制器向提醒装置发送提醒信息， 提醒用户 修正摆放位置。 所述提醒信息可以为扬声器响声、 马达振动、 显示灯中的一种 或者多种， 提醒的频率可以设置为较长间隔， 或者在检测到符合条件的预定吋 间段内以第一频率发送提醒， 然后以第二频率发送提醒， 其中， 第一频率大于 第二频率。
[0050] 本发明实施例通过对便携设备的运动状态进行检测， 并结合便携设备的朝向信 息， 使得设备在闲置吋能有效的提醒用户进行充电， 提高用户使用的便利性。
[0051] 实施例四：
[0052] 图 5示出了本发明第四实施例提供的便携设备的发电装置的结构示意图， 详述 如下：
[0053] 在实施例一的基础上， 所述发电装置还包括运动传感器 51、 距离传感器 52、 控 制器 53和提醒装置 54， 所述运动传感器 51用于检测便携设备的运动状态信息， 所述距离传感器 52用于检测所述显示面或者触控面是否有遮挡物， 当所述控制 器 53接收所述运动传感器 51检测到所述便携设备为静止状态吋， 并且所述距离 传感器 52检测便携设备的正面有遮挡物吋， 控制器 53向所述提醒装置 54发送提 醒指令。
[0054] 与实施例三类似的， 所述运动传感器用于检测用户是否在使用便携设备， 当用 户没有使用便携设备吋， 通过距离传感器检测所述便携设备的正面是否有遮挡 特征， 所述距离传感器可以红外传感器、 电容式距离传感器等， 在检测到预设 的距离范围内没有遮挡物吋， 表明设备当前摆放的位置没有被其它物品遮挡， 有利于便携设备进行充电， 当检测到预设的距离范围内有遮挡物吋， 则发送提 醒信息， 提醒用户改变摆放位置。
[0055] 其中， 所述提醒信息可以为扬声器响声、 马达振动、 显示灯中的一种或者多种 ， 提醒的频率可以设置为较长间隔， 或者在检测到符合条件的预定吋间段内以 第一频率发送提醒， 然后以第二频率发送提醒， 其中， 第一频率大于第二频率
[0056] 本发明实施例通过对便携设备的运动状态进行检测， 并结合便携设备的正面是 否有遮挡物， 使得设备在闲置吋能有效的提醒用户进行充电， 提高用户使用的 便利性。
[0057] 实施例五：
[0058] 图 6为本发明第五实施例提供的便携设备的发电装置的结构示意图， 详述如下

[0060] 所述便携装置在使用电阳能薄膜电池层进行充电吋， 为了提高充电效率， 常会 将便携装置旋转在光线较为充足的场景下进行充电， 由于光线较强的场景下， 往往容易会产生温度的上升， 因此， 为了保护电能存储器， 比如可充电电池， 对所述电能存储器的温度进行监控， 当温度大于预设的温度值吋， 则发送提醒 信息， 或者控制充电幵关断幵， 停止进一步充电， 以免发生危险事故。 [0061] 所述提醒信息可以为扬声器响声、 马达振动、 显示灯中的一种或者多种， 提醒 的频率可以根据温度的变化而提高， 比如设定多个温度值与频率的对应关系， 当温度越高吋， 提醒的频率越快， 或者提醒的方式也越多。
[0062] 本发明实施例通过检测电能存储中的可充电电池的温度， 使得便携设备在充电 过程中， 当出现温度过高吋， 及吋有效的提醒用户， 提高便携设备的发电装置 的使用安全性。
[0063] 以上所述仅为本发明的较佳实施例而已， 并不用以限制本发明， 凡在本发明的 精神和原则之内所作的任何修改、 等同替换和改进等， 均应包含在本发明的保 护范围之内。
