现有技术中存在的问题是，太阳能移动电源包括太阳能电池板、旋转轴、壳体、蓄电池、光伏充电控制器和AC电源插口，其结构复杂，制造成本高，体积大；另外，太阳能电池板实现太阳能转换电能的转换效率较低，且太阳能光伏电池板多为非柔性或柔性较差，不能折叠和卷曲或折叠、卷曲后容易损坏太阳能电池，而且太阳能光伏电池板重量较大，以上原因导致现有技术的太阳能移动电源不方便携带。
实用新型内容
为此，本实用新型所要解决的技术问题在于现有技术太阳能充电器结构复杂、体积大，不能折叠和卷曲或折叠、卷曲后容易损坏太阳能电池，导致不方便随身携带并且太阳能转换电能效率低的问题，从而提出一种结构简单、体积小，可折叠、卷曲并且太阳能转换电能效率高的便携式太阳能充电器。

所述下表层的厚度范围为0.1-0.2mm。
所述电能输出装置为接线盒，所述接线盒内设有集成线路板，用于对太阳能薄膜电池组件转换成的电能进行控制，使输出的电压满足负载的使用要求；所述接线盒上设有用于连接负载的至少一个USB接口。
所述集成线路板上设置至少一个能够显示光照强度的显示灯。
所述导线位于所述第一柔性保护膜层与第三柔性保护膜层之间，并穿过所述粘结层和第一柔性保护膜层的下表层以连接至所述电能输出装置上。
所述太阳能薄膜电池组件包括至少一块CIGS太阳能薄膜电池，所述CIGS太阳能薄膜电池至上而下依次包括阻水膜、CIGS太阳能薄膜电池芯片、阻水膜。
所述充电器本体上设有用于挂接的至少一个通圈。
本实用新型的上述技术方案相比现有技术具有以下优点：
1.本实用新型的便携式太阳能充电器，其通过采用太阳能薄膜电池组件，大大提高了太阳能转换为电能的转换效率，而且太阳能薄膜电池质量轻，有利于用户随身携带；并且，充电器本体由第一柔性保护膜层封装而成，其第二柔性保护膜层以及第三柔性保护膜层也是柔性的，固定设置在充电器本体内侧面上的太阳能薄膜电池组本身也是柔性的，以上设置使得本实用新型的便携式太阳能充电器可折叠、卷曲，用户可以将充电器收纳为较小体积，大大方便了用户随身携带；另外，通过第一柔性保护膜层、第二柔性保护膜层和第三柔性保护膜层的设置，可以阻隔湿气、高温、紫外线等对太阳能薄膜电池组件的损害，以及避免了机械、化学方面损伤，保证了本实用新型的便携式太阳能充电器工作的可靠性和稳定性。
2.本实用新型的便携式太阳能充电器，在集成线路板上设置至少一个能够显示光照强度的显示灯，显示灯起到指示作用，用于指导用户使用。
3.本实用新型的便携式太阳能充电器，通过在充电器本体上设置通圈，使得用户外出时可以方便地将太阳能充电器挂接到背包、挎包上，进一步方便了用户携带。

通过第一、第二、第三柔性保护膜层以及太阳能薄膜电池组件的封装，本实用新型的便携式太阳能充电器可折叠、弯曲，而且质量轻便，方便用户携带。
进一步具体地，本具体实施方式的所述第一柔性保护膜层31至上而下依次包括粘结层311、下表层312。同上，所述粘结层311为热熔胶层，例如EVA层；所述下表层312为不透光、柔性的防水材料，例如防水布。通过第一、第二、第三柔性保护膜层的设置，可以阻隔湿气、高温、紫外线等对太阳能薄膜电池组件2的损害，以及避免了机械、化学方面损伤，保证了本具体实施方式的便携式太阳能充电器工作的可靠性和稳定性。
再进一步地，所述电能输出装置为接线盒4，所述接线盒内设有集成线路板，用于对太阳能薄膜电池组件转换成的电能进行控制，使输出的电压满足负载的使用要求；所述接线盒4上设有用于连接负载的至少一个USB接口41，用于与负载连接。其中，所述负载可以是手机、平板电脑、笔记本电脑、智能手表、充电包等移动设备。

在本具体实施方式中，所述导线5位于所述第三柔性保护膜层与第一柔性保护膜层31之间，并穿过所述粘结层311和下表层312以连接至所述接线盒4上。进一步地，所述导线5优选为镀锡编织铜带。
再者，所述充电器本体1上设有用于挂接的至少一个通圈11，具体地，在本具体实施方式中，所述通圈11设置为四个，分别设置在充电器本体1的四个角上，通过通圈11的设置，用户可以方便地把本具体实施方式提供的便携式太阳能充电器挂接到用户随身携带的包上，例如背包、挎包等。当然，通过通圈11，本具体实施方式的便携式太阳能充电器还可以挂接到户外光照条件较好位置的固定装置上。
显然，上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引伸出的显而易见的变化或变动仍处于本实用新型创造的保护范围之中。
