Description

便携式太阳能发电器
技术领域
本发明涉及一种太阳能发电器，特别涉及一种便携式太阳能发电器。
背景技术
随着能源危机的恶化和环保意识的加强，人们对洁净能源的关注日益增强，而太阳能做为目前较为成熟的洁净能源运用已成为能源领域的研究热点。
太阳能的收集主要是利用太阳能电池板将太阳辐射的光子通过半导体物质转变为电能(请参见“Grown junction GaAs solar cell”，Shen，C.C.；Pearson，G.L.；Proceedings of the IEEE，Volume 64，Issue3，March 1976Page(s)：384-385)。太阳能电池板的光电转换过程是指太阳辐射到太阳能电池板上的一部分光子与半导体的原子及价电子产生电子-空穴对。在所述电子-空穴的作用下，半导体材料在P-N结附近形成光生伏打电动势，只要在半导体材料的P型区和N型区焊上金属导线便可利用所述光生伏打电动势对外供电。将所述具有光生伏打电动势的半导体材料串联、并联起来就形成了能输出一定电压和电流的太阳能电池板。
随着微电子技术的飞速发展，越来越多的便携式电子装置，如手机、PDA、Notebook、PSP等已被广大消费者所使用。实现电子装置的便携功能需要解决的一个重要问题便是电子设备的持续供电能力，而环保、洁净且取用方便的太阳能成为解决这一问题的一大突破口。然而，现有的太阳能发电器多为固定安装的大面积太阳能电池板，因其体积、重量过大而不便于携带外出。
发明内容
有鉴于此，有必要提供一种便于携带的便携式太阳能发电器。
一种便携式太阳能发电器，其包括一空心旋转轴及至少二个结构相似的容置单元。所述容置单元上设置有一开放式空腔，所述开放式空腔内设置有相互连接的太阳能电池板。每个所述容置单元上均开设有一位置相互对应的通孔，所述空心旋转轴穿过所述容置单元上的通孔将所述至少二个容置单元并连，所述容置单元绕所述空心旋转轴旋转展开或层叠。所述空心旋转轴内设置有蓄电装置。所述空心旋转轴对应于每一个容置单元所处的位置均开设有导线通孔，所述容置单元内的太阳能电池板通过传输导线穿过对应的导线通孔进入空心旋转轴内部与所述蓄电装置相连接以将收集到的电能存储至所述蓄电装置内。
相对于现有技术，本发明所提供的便携式太阳能发电器采用旋转展开和层叠的结构以及在空心旋转轴内设置蓄电装置的设计减少了太阳能发电器的体积，提高了太阳能发电器的便携性。
附图说明
图1为本发明实施方式所提供的便携式太阳能发电器第一状态示意图。
图2为图1中的便携式太阳能发电器的容置单元的结构示意图。
图3为沿图1的III-III方向的剖面示意图。
图4为图1所提供的便携式太阳能发电器第二状态示意图。
具体实施方式
如图1、图2所示，本发明所提供的便携式太阳能发电器2包括一空心旋转轴20、至少二个容置单元22及一供电接口24。每个所述容置单元22上均开设有一通孔221，所述通孔221可开设于所述容置单元22的一端或中间位置。在本实施方式中，所述通孔221设于所述容置单元22的其中一端。所述空心旋转轴20穿过所述容置单元22上的通孔221将所述至少二个容置单元22并连，所述容置单元22绕所述空心旋转轴20旋转展开或层叠。所述供电接口24通过供电导线240与所述空心旋转轴20相连接。
所述容置单元22上设置有一开放式空腔222。所述开放式空腔222内设置有多个通过传输导线226相互连接的太阳能电池板223，所述太阳能电池板223的连接方式为串联或并联。在本实施方式中，所述太阳能电池板223为串联连接。所述容置单元22的开放式空腔222上设置有透明的保护面板224，其用于保护设置于所述开放式空腔222内的太阳能电池板223。所述保护面板224上设置有与所述太阳能电池板223相对应的聚焦透镜225。所述聚焦透镜225的面积比对应的太阳能电池板223的面积大，可以将较大范围的太阳光汇聚到较小面积的太阳能电池板223上，减少了太阳能电池板223的需求面积，降低了产品成本。
如图3及图4所示，所述空心旋转轴20两端分别设有挡块202以防止并连在空心旋转轴20上的容置单元22由空心旋转轴20两端脱离。所述空心旋转轴20内设置有蓄电装置200。所述空心旋转轴20对应于每一个容置单元22均开设有导线通孔201，所述每一个容置单元22内用于连接太阳能电池板223的传输导线226通过对应的导线通孔201进入空心旋转轴20内部与所述蓄电装置200相连接。所述传输导线226将太阳能电池板223所转换的电能传输至蓄电装置200内储存。所述供电接口24通过供电导线240由空心旋转轴20位于底部的挡块202处进入空心旋转轴20内部与所述蓄电装置200相连接，所述便携式太阳能发电器2通过供电接口24向外部装置提供电能。
当所述便携式太阳能发电器2需要收集太阳能时，将所述每个容置单元22绕所述空心旋转轴20旋转展开。所述每个容置单元22内的太阳能电池板223接收由保护面板224上的聚焦透镜225所汇聚的太阳光线并将其转化为电能再通过传输导线226将电能储存在设置于空心旋转轴20内的蓄电装置200(见图3)中。
与现有技术相比，本发明提供的便携式太阳能发电器采用空心旋转轴并连多个容置单元以组成旋转展开和层叠的结构，并通过设置于容置单元内的太阳能电池板和传输导线将太阳能转化为电能并储存在空心旋转轴内的蓄电装置中。此种设计减小了太阳能发电器的体积，提高了太阳能发电器的便携性。
最后应说明的是，以上实施方式仅用以说明本发明的技术方案而非限制，尽管参照较佳实施方式对本发明进行了详细说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或等同替换，而不脱离本发明技术方案的精神和范围。
