附图说明
图1为本发明便携式充电宝一实施例的结构示意图；
图2为本发明便携式充电宝二实施例的结构示意图；
图3为本发明便携式充电宝一实施例中内部系统架构结构示意图。
本发明目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
具体实施方式
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。
本发明提供一种便携式充电宝，参照图1至图3，在一实施例中，该便携式充电宝包括壳体10、用于直接与待充电设备的充电接口连接的充电输出接口20、设于壳体10内的充电电池30和用于控制所述充电输出接口20输出充电电流的充电控制电路40；所述充电输出接口20凸设于所述壳体10外，且与所述壳体10连接。
本发明实施例提供的额便携式充电宝主要应用于充电系统中，用于为待充电设备进行充电。上述待充电设备可以为手机和pad等智能移动终端，以下以手机为例作出详细说明。在手机中通常采用的充电接口包括安卓系列的充电接口和苹果系列的充电接口，对应的上述充电输出接口20可以包括Micro USB输出接头或者iPhone lightening USB输出接头。
本实施例提供的便携式充电宝主要应用于用户进行应急充电，具体地，上述充电电池30的容量较小，上述壳体的体积较小。在使用时可以将便携式充电宝的充电输出接口插入手机的充电接口中，从而使得便携式充电宝与手机直接连接，以为手机进行充电。为了减小便携式充电宝的重量，优选地，可以采用塑胶材料注塑成型。
本发明实施例通过在壳体10上设置充电输出接口20，通过该充电输出接口20直接插入到待充电设备的充电接口中，从而实现对待充电设备的充电。相对于现有技术采用数据线连接充电宝和待充电设备，由于本发明可以直接实现便携式充电宝和待充电设备之间的连接，因此提高了充电的便利性。
进一步地，基于上述实施例，本实施例中，上述外壳10的一面设有凸块，所述充电输出接口20与所述壳体10连接的一端设于所述凸块远离壳体10的一侧。
本实施例中，上述凸块的形状和大小可以根据实际需要进行设置，优选地，该凸块呈长方体设置，且横向截面面积略大于充电输出接口20。由于在本实施例中，将充电输出接口20设置在凸块，从而增加了充电输出接口20顶端到外壳10之间的距离，使待充电设备和壳体10之间具有容纳壳套的空隙。当用户在使用壳套套设于待充电设备的外部时，可以直接将充电输出接口20插入到待充电设备的充电接口中进行充电，无需去掉壳套，因此可以提高便携式充电宝的应用范围，减小充电的操作难度。
进一步地，基于上述实施例，本实施例中，上述便携式充电宝还包括保护盖50，所述保护盖50与所述壳体10、所述凸块或充电输出接口20卡合固定连接，且所述充电输出接口20位于所述保护盖50内。
本实施例中，上述保护盖50卡合固定的方式可以根据实际需要进行设置，例如，可以在保护盖50的内壁设置卡槽或者凸台；在与之配合的壳体10、所述凸块或充电输出接口20上对应设置凸台或卡槽。通过卡槽和凸台的配合，使得保护盖50卡合固定。本实施例中，由于设置保护盖50可以减小充电输出接口20与外界接触的可能，防止充电输出接口20受损，因此可以延长便携式充电宝的使用寿命。
进一步地，基于上述实施例，本实施例中，上述便携式充电宝还包括伸缩连接组件，所述充电输出接口20通过所述伸缩连接组件与所述壳体10连接，所述伸缩连接组件用于控制所述充电输出接口20收容于所述壳体10内或者凸出所述壳体10设置。
本实施例中，上述壳体10可以设置一容置腔收容该连接组件和充电输出接口20，可以理解的是，伸缩连接组件的结构可以根据实际需要进行设置，只要能够实现充电输出接口20的两种状态即可，该两种状态包括充电输出接口20凸出壳体10的第一状态和充电输出接口20收容于容置腔内的第二状态。具体地，当需要进行充电时，可以通过伸缩连接组件控制充电输出接口20。
进一步地，基于上述实施例，本实施例中，上述充电控制电路40包括控制芯片41、升压电路42和拨动开关43，其中所述充电电池30通过所述拨动开关42分别与所述控制芯片41和所述升压电路42连接；所述升压电路42的输入端通过所述拨动开关43与所述控制芯片41连接，输出端与所述充电输出接口20连接；所述控制芯片41用于对所述充电电池30的放电电压和放电电流进行检测，并根据检测的结果输出控制信号至所述升压电路42的工作状态。
本实施例中，上述控制芯片41可以根据待充电设备的当前充电情况输出控制信号至升压电路42，以实现恒压充电和恒流充电，且可以改变充电的方式，例如刚开始采用恒流充电，当待充电设备的电压上升至预设值时，可以控制升压电路42以恒压充电方式输出充电电流至充电输出接口20以进行恒压充电。
可以理解的是，上述控制芯片41保护电压检测端和电流检测端，用于对于升压电路42输出的电压和电流进行检测，以防止过度充电和放电。当检测到过度充电或放电时，由控制芯片41输出控制信号至升压电路42，以停止放电输出（即停止对待充电设备的充电）。
进一步地，基于上述实施例，本实施例中，上述充电控制电路40还包括LED指示灯44，所述LED指示灯44与所述控制芯片41连接。
本实施例中，控制芯片41可以根据当前的充电状态输出控制信号LED指示灯44的亮和灭，从而提示用户知道当前的充电状态。具体地，LED指示灯44的显示状态可以根据实际需要进行设置，例如充电时LED指示灯44以闪烁或是颜色变换来提示充电进行或充电完毕。
进一步地，基于上述实施例，本实施例中，上述便携式充电宝还包括设于所述壳体10上的充电输入接口60和充电控制电路70，所述充电输入接口60通过所述充电控制电路70与所述充电电池30连接。
本实施例中，上述充电电路70的结构可以根据实际需要进行设置，在此不做进一步地限定。
以上仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
