Description

充电宝及组合式终端设备 技术领域
本发明涉及移动终端，特别是涉及一种充电宝以及由充电宝和移动终端拼接而成的组合式终端设备。
背景技术
现有技术中，手机显示屏的长宽比一般锁定为16:9或16:10。为了能够在显示屏上尽可能地实现单手触摸操作，此时的显示屏的面积一般都很小，例如显示屏为3.5寸，远远无法满足人们对大显示面积的需求。但是，当显示屏的显示面积设置成足够大时，例如5.5寸的显示屏，此时由于受前述长宽比的限制，显示屏的宽度太大，通常已经无法进行单手操作。
而且，按照前述的长宽比设计的显示屏，其在显示大部分为A4纸张尺寸的出版物文档时，显示屏周边通常会留有黑边，这不但影响影响显示效果而且也没有实现对显示屏的最大化利用。
再者，由于手机的更新换代非常快，手机使用者更换手机的频率也越来越快。旧手机的丢弃会造成严重的资源浪费和环境污染。现在的市场上还没有很好的解决方案，一般采取回收手机的方法，这样不仅废旧手机的再生成本会变高，而且还会造成在回收再生中的二次污染。
此外，由于手机的屏幕越来越大导致用电量增加，另一方面手机的厚度却有变薄的趋势导致手机的电池不能做的很大，从而现在的手机都普遍存在电量不足的问题。

本发明还提供一种组合式终端设备，由一个或多个移动终端和至少一个权上述技术方案中任一项所述的充电宝在所述充电宝的所述显示屏的宽度方向上和/或长度方向上拼接而成，其中，由所述移动终端向所述充电宝提供其显示屏的显示数据，并且由所述充电宝的所述蓄电池为所述移动终端提供电力。
优选地，在所述拼接的方向上，所述充电宝的所述显示屏与所述移动终端的显示屏具有相同的宽度或长度。
首先，根据上述技术方案，本发明涉及的移动终端能够相互拼接来形成一个组合式终端设备，这样移动终端的显示屏可以设置成适合单手操作的宽度，并进而通过拼接形成组合式终端设备来满足人们对大显示面积的需求。并且，由于移动终端能够拼接，所以通过设置合适的移动终端的尺寸以及拼接的个数就能使拼接而成的组合式终端设备的显示屏为A4纸张比例，这样的组合式终端设备的显示屏观在对出版物文档进行显示时就能消除黑边。而且，当由符合本发明技术方案的旧移动终端来进行拼接形成组合式终端设备时，还能解决旧移动终端回收再生中产生的二次污染问题。
其次，根据本发明的技术方案，本发明涉及的移动终端的显示屏相反的两侧，例如左右侧或/上下侧具有相互能够吸引的第一磁性吸附元件和第二磁性吸附元件，这样一个移动终端的第一磁性吸附元件/第二磁性吸附元件能与其它移动终端的第二磁性吸附元件/第一磁性吸附元件进行相互吸引，来形成移动终端间相互拼接的状态。由于第一磁性吸附元件和第二磁性吸附元件，移动终端上不用设置专门的用于进行拼接的插槽，从而能保持移动终端的使用手感。并且，显示屏的第一侧表面和第二侧表面相互平行，从而一个移动终端能与其它移动终端在侧面上进行贴合，并使由多个移动终端组成的组合式终端设备的屏幕在同一水平面上，提高了显示效果及观看感受。
再者，当本发明涉及的移动终端在靠近背面侧设置有左右磁性吸附元件时，不同移动终端的背面能够相互吸引在一起。也就是说，不同移动终端能在显示屏所在方向拼接成一个组合式终端设备，而当将组合式终端设备拆解为多个移动终端时，移动终端之间能够能通过左右磁性吸附元件两两吸附在一起，不但方便了移动终端的携带，而且降低了移动终端丢失的风险。背面侧是指移动终端的背面，或者设置在移动终端内部且靠近移动终端背面一侧。
并且，根据上文对本发明技术方案的描述可知，在本发明的一个技术方案中，相比于现有技术中显示比例为16:9或16:10(即长宽比为1.78或1.6)的显示屏，本发明将显示屏的长宽比设置成至少为2.5。因此，本发明的显示屏在形状上更为细长。这样，在相同的宽度下，本发明的显示屏具有更大的显示面积。或者换句话说，在相同的显示面积下，本发明的显示屏可以具有较小的宽度，以方便人们进行单手操作。
而且，通过将显示屏相比于现有技术显著拉长之后，可以惊奇地发现，这样的显示屏在易于手机使用者单手操作的同时，更容易用多个显示屏以单排拼接的方式来实现A4纸张的对应比例，尽管本发明不限于单排拼接。而且，可以设想，当某个用户由于手机的更新换代而保留有多个具有这种显示屏的手机时，他可以将这些手机进行前述的拼接，而形成一个组 合式终端设备。
可以理解，具有按照本发明的显示屏的手机被使用者淘汰时，通常可能是由于无关显示屏的其它原因，如CPU或存储空间的不足。而本发明的提出的这种具有特定长宽比的显示屏恰好为被淘汰的旧手机提供了对应的利用价值，这是因为当包括旧手机在内的多个手机拼接成组合式终端设备时，其主要利用的就是旧手机的显示屏的显示功能，而该组合式终端设备的其它能力可以由该组合式终端设备中性能更好的新手机来提供。
特别是，显示屏的一个主要功能是向使用者提供文档阅读，当通过拼接合适数量的移动终端使得组合式终端设备的显示屏基本为A4纸张的比例时，可以基本上消除以A4比例为载体的出版物文档显示时出现的黑边问题。这方便用户在拼接的显示屏上阅读A4比例的文档，对于旧手机的利用价值的提升更为显著。
而根据本发明提供的充电宝，由于整体上为扁平板状，蓄电池所占区域的面积不小于前表面的面积的70％，在蓄电池厚度不变的情况下能够增加蓄电池的体积，能够为手机提供更长时间的充电服务；并且，由于显示屏的显示区域的面积不小于前表面的面积的70％，从而本发明的充电宝具有较大的显示屏，在充电宝与手机等移动终端连接时，该显示屏能够与移动终端的显示屏一起显示。当充电宝的显示屏设置成适合单手操作的宽度，并进而通过与移动终端拼接形成组合式终端设备来满足人们对大显示面积的需求。并且，由于充电宝能够拼接，所以通过拼接合适数量与尺寸的移动终端就能使拼接而成的组合式终端设备的显示屏为A4纸张比例，这样的组合式终端设备的显示屏观在对出版物文档进行显示时就能消除黑边。本发明的一个实施例中，充电宝在与移动终端拼接时，一方面为移动终端提供充电，另一方面充电宝的显示屏与移动终端的显示屏一起形成为A4纸张比例来显示内容。
根据下文结合附图对本发明具体实施例的详细描述，本领域技术人员将会更加明了本发明的上述以及其他目的、优点和特征。

具体实施方式
如图1所示，本发明提供一种移动终端20，移动终端20与现有技术的不同之处在于其用于由多个移动终端20拼接成一个图2-图5之一所示的组合式终端设备30。为了便于拼接，如图1所示，移动终端20整体上为不带圆角的矩形。组成组合式终端设备30的移动终端20可以相同也可以不同，但移动终端20均应包括：显示屏10；以及位于显示屏10的相反两侧的第一侧表面SL和第二侧表面SR，其中，第一、第二侧表面SL、SR为相互平行的平面。在图1中，第一侧表面SL和第二侧表面SR分别为左侧面、右侧面，在其它实施例中第一侧表面SL和第二侧表面SR也可以为上侧面和下侧面，在另外实施例中第一侧表面SL和第二侧表面SR也可以为左侧面和右侧面以及上侧面和下侧面。
在第一侧表面SL处的第一磁性吸附元件(图中未示出)和设置在第二侧表面处的第二磁性吸附元件(图中未示出)。第一、第二吸附元件可以为铁、钴、镍以及能够吸引铁、钴、镍的磁性材料。第一和第二磁性吸附元件的位置布置成：当将另一移动终端与当前移动终端拼接时，该移动终端的第一侧表面处SL的第一磁性吸附元件与另一移动终端的第二侧表面处的第二磁性吸附元件能够相互吸引，以使得当前移动终端的第一侧表面与另一移动终端的第二侧表面相互对准地贴合。根据该技术方案，一个移动终端的第一磁性吸附元件/第二磁性吸附元件能与其它移动终端的第二磁性吸附元件/第一磁性吸附元件进行相互吸引，来形成移动终端间相互拼接的状态。由于第一磁性吸附元件和第二磁性吸附元件，移动终端20上不用设置专门的用于进行拼接的插槽，从而能保持移动终端的使用手感。并且，显示屏10/移动终端20的第一侧表面SL和第二侧表面SR相互平行，从而一个移动终端能与其它移动终端在侧表面上进行贴合，并使由多个移动终端20组成的组合式终端设备30的屏幕在同一水平面上，提高了显示效果及观看感受。
在本发明的一个实施例中，第一磁性吸附元件不凸出于第一侧表面SL，且第二磁性吸附元件不凸出于第二侧表面SR。这包括两种情况：一种是，第一磁性吸附元件属于第一侧表面SL的一部分(或者说第一磁性吸附元件与第一侧表面SL平齐)，第二磁性吸附元件属于第二侧表面SR的一部分(或者说第二磁性吸附元件与第二侧表面SR平齐)，拼接时 不同移动终端的第一侧表面SL第二侧表面SR直接接触并相互吸引。另一种是，第一磁性吸附元件设置于第一侧表面SL之下，第二磁性吸附元件设置于第二侧表面SR之下，第一磁性吸附元件与第二磁性吸附元件相互吸引，并且第一侧表面SL第二侧表面SR相互接触而第一磁性吸附元件与第二磁性吸附元件并不相互接触。
在本发明的一个实施例中，移动终端20还包括设置在第一侧表面处的第一导电触点和设置在第二侧表面处的第二导电触点。第一和第二导电触点位置布置成：当前移动终端20的第一侧表面与另一移动终端20的第二侧表面相互对准地贴合时，该移动终端20的第一侧表面处的第一导电触点与另一移动终端20的第二侧表面处的第二导电触点能够相互电接触，从而能通过第一导电触点与第二导电触点在不同移动之间进行充放电操作及数据传输操作。就单个移动终端20来说，可以设置与第一导电触点或第二导电触点相配的底座，底座与第一导电触点或第二导电触点相接触来进行充电或者数据传输。需要特别注意的是，当多个移动终端20形成组合式终端设备30时，各个移动终端20之间的拼接处由于第一磁性吸附元件与第二磁性吸附元件而相互吸引，此时不同移动终端20之间的第一、第二导电触点能够紧密的贴合在一起，保证了充电及数据传输的稳定性。
由上所述可知，由于第一导电触点和第二导电触点直接接触，若是硬连接可能会对第一导电触点和第二导电触点产生损伤，所以本发明将第一导电触点和第二导电触点中的至少一个设计为由弹性材料制成或者被弹簧偏压，使其能够在垂直于其所在的侧表面的方向上移动来产生一定的移动量。由于具有一定的移动量，能够在保证第一导电触点和第二导电触点接触时还防止第一导电触点和第二导电触点的损伤。
如图6所示，本发明还提供一种第一导电触点和第二导电触点的设计方案：在图6中，第一导电触点41有多个弓形金属片组成。第二导电触点42为一很薄的金属片，其外边缘可以与第二侧表面SR平齐，但整体上凹入第二侧表面SR内部。当如图6所示的那样将一个移动终端20的第一导电触点41与另一移动终端的第二导电触点42相向运动并最终使第一导电触点41和第二导电触点42抵触时，由弓形金属片制成的第一导电触点41会在垂直于其所在的第一侧表面SL的方向上产生形变来使图6中第二侧表面SR与第一侧表面SL相互对准地贴合。图6中实线部分的第一导电触点41表示形变前的第一导电触点41，虚线部分的第一导电触点41表示产生形变后的第一导电触点41。
如图7所示，本发明还提供另外一种第一导电触点和第二导电触点的设计方案：在图7中，第一侧表面SL具有第一凹槽43，第一导电触点41可旋转地连接于第一凹槽43内，例如通过转轴与第一凹槽43的两个壁面可旋转的连接。如图7实线部分所示，第一导电触点41能旋出第一凹槽43外以与另一移动终端的第二导电触点42接触，而第二导电触点42为由金属片簧组成的结构。如图7虚线部分所示，第一导电触点41能向第一凹槽43内旋转以断开与另一移动终端的第二导电触点42的接触。
可以看出，在上述两种第一导电触点41和第二导电触点42的设计中，第一导电触点41形成为可在伸出位置和缩回位置之间移动的活动触点；其中，当活动触点处于伸出位置时凸出于其所在的侧表面。在其它实施例中，第二导电触点42也可以设置为活动触点，如 在图6和图7中的第二导电触点42可以设置为向内凹陷的弓形金属片。当第一导电触点41和第二导电触点42均为活动触点时，能进一步增加两者的抗损伤性能。
在上述两种第一导电触点41和第二导电触点42的设计中，活动触点所在的侧表面具有用于容纳活动触点的凹入部即第一凹槽43。在其它实施例中，当为活动触点的第一导电触点41或第二导电触点42通过手动拨动来相对于其所在的侧表面伸出与缩回时，此时凹入部为孔洞形状，第一导电触点41或第二导电触点42通过该孔洞形状的凹入部伸出或缩回。凹入部上还设置有触点盖，触点盖可拆卸的连接于凹入部，用来封闭凹入部，并且当将触点盖封闭凹入部时，触点盖与其所在的侧表面平齐，这样触点盖的设计能起到对凹入部内部件的防尘作用，并且由于其能与所在的侧表面平齐，从而也不影响移动终端20的使用手感。
如上文所述，第一侧表面SL或第二侧表面SR用于拼接贴合，从而尽量不在第一侧表面SL或第二侧表面SR设置手机的按键。但若移动终端20的四个侧面均要与其它移动终端20拼接时，可以在第一侧表面SL或第二侧表面SR上设置第二凹槽，手动操作按键设置在第二凹槽内，并使得手动操作按键的轮廓不超过其所在侧表面。当然，在一个实施例中，第二凹槽可以与第一凹槽相同。
图8是根据本发明一个实施例的设置左右磁性吸附元件的移动终端的结构示意图，具体地是背面示意图。图8中，在移动终端20的背面50的一侧设置有沿显示屏的宽度方向布置的左磁性吸附元件和右磁性吸附元件，在图8中左右磁性吸附元件为一个磁铁60。在其它实施例中，左右磁性吸附元件也可以为不同的部件，例如左磁性吸附元件为磁铁，而右磁性吸附元件为铁质元件。这样，参见图9和图10，当将另一移动终端与该移动终端20背靠背相抵触时，该移动终端的磁铁60的N极和S极能够分别与另一移动终端磁铁的S极和N极相互吸引，从而使得两个移动终端的背面具有相互对准且贴合的趋势。这样，不同移动终端能在显示屏10所在方向拼接成一个组合式终端设备30，而当将组合式终端设备30拆解为多个移动终端时，移动终端之间能够能通过磁铁两两吸附在一起，不但方便了移动终端的携带，而且降低了移动终端丢失的风险。
图4是根据本发明一个实施例的组合式终端设备的示意图，在图4中的组合式终端设备30由四个移动终端20拼接而成，图4中移动终端20的两个长边为无边框设计。如图5所示，本发明提供的组合式终端设备30由五个移动终端20沿着显示屏10的宽度方向拼接而成，并且拼接时各移动终端20均对齐，这样显示屏10的长度L充当组合式终端设备的宽度W’。在图5中，移动终端20为手机，在其它实施例中，移动终端20还可以为平板电脑。在图4和图5中，组合式终端设备的长度L’、宽度W’均为297mm、210mm。也就是说，在图4中的移动终端20的宽度W为59.4mm，长度L为210mm，L:W＝3.5；在图5中的移动终端20的宽度W为74.25mm，长度L为210mm，L:W＝2.8。由图4-图5中的组合式终端设备来显示出版物文档，不但能全屏无黑边的进行显示，而且此时字体与出版物纸质的字体大小完全相同。
上述图4-图5中的组合式终端设备还可以使用窄边框的移动终端并沿着显示屏10的宽度方向拼接而成，例如此处可以定义或限定边框的宽度小于1mm将为窄边框，当然边框的 宽度还可以根据需要来进行限定。根据本发明的构思，本发明优先使用如图4和图5所示的在显示屏10的宽度方向的两个侧边设计为无边框的移动终端20，此时能使各移动终端20的拼接处对阅读基本无影响，而随着显示屏10的宽度方向的两个侧边的宽度增加，会逐渐对阅读产生不利影响。
回到图1，图1所示的移动终端20具有显示屏10，在显示屏10的宽度方向上，移动终端20的相对设置的两个侧边设置为无边框的形式。图1中，x方向为显示屏的长度方向，y方向为显示屏的宽度方向。从图1-图5可以看出，显示屏10基本上为矩形。显示屏10可以设置为L:W≥2.5，其中L为显示屏的长度，W为显示屏的宽度。因此，在本发明的一些实施例中，显示屏10在形状上为细长状。这样，在相同的宽度下显示屏10具有更大的显示面积。或者换句话说，在相同的显示面积下，该种显示屏10可以具有较小的宽度，以方便人们进行单手操作。并且在易于手机使用者单手操作的同时，更容易用多个显示屏以单排拼接的方式来实现A4纸张的对应比例。
根据本发明的一个实施例，该矩形显示屏的长宽比可以限制为：
L:W＝(205～215):[(290～304)/n]，              (1)
其中n为正整数且n≥2。通过该种设置，当由n个移动终端20拼接而成组合式终端设备30时，组合式终端设备30的长宽比为(290～304)/(205～215)，也就是说由移动终端20拼接的组合式终端设备30的显示面积的长宽比基本等于297:210，从而无论字体大小如何显示屏10均能全屏无黑边的显示出版物文档。
在本发明的一个优选实施例中，将n设置为小于等于6。并且当n取值4或5时，不但能使显示屏10具有较大的显示面积而且又不至于使显示屏10过于细长而影响到移动终端20的使用。在本发明的一个优选实施例中，W为58～61mm，L为205～215mm，尤其是当W为60mm，L为210mm时，五个移动终端20可以组成长宽比基本为297:210的组合式终端设备30。当W为72～76mm，L为205～215mm，尤其是W为74mm，L为210mm时，四个移动终端20可以组成长宽比基本为297:210的组合式终端设备30。根据本发明的显示屏10和移动终端20，在具有较大显示面积的同时还特别适合于单手操作。而由多个移动终端20拼接而成的组合式终端设备30，其长宽比基本等于297:210，从而能够全屏无黑边的显示出版物文档。
需要理解的是，前文用公式(1)描述的对移动终端显示屏的长宽比的限制条件可以并不局限于较为细长的显示屏(如长宽比不小于2.5的显示屏)，而是可以作为一个独立的限制条件。例如，对于公式(1)，其中的n可以取值为2或3。此时，该长宽比的大致为1.41和2.12。尽管此时的单个显示屏并不显得那么细长，但是依然有利于拼接成A4纸张比例的显示屏。特别是，当用两或三个这样的显示屏来拼接与A4纸张实际尺寸基本相同的显示屏时，该显示屏的长度L可以为205～215mm。
进一步地，需要理解的是，对于单纯地为了方便于拼接与A4纸张实际尺寸基本相同的显示屏时，其中移动终端的显示屏可以为矩形，且其长度或宽度为205～215mm。当由多个移动终端成单排拼接成一个组合式终端设备30时，这些移动终端的长度或宽度具有相同的 尺寸且205～215mm之间取值。这样，当这些移动终端沿着该相同尺寸的长度或宽度对齐拼接好后，所形成的单个矩形屏幕在整体上则具有205～215mm的宽度。所拼接的单个矩形屏幕的长度则可以为290～304mm，这可以通过选择参与拼接的移动终端的数量来实现，或者通过选择移动终端的另一不同尺寸侧的长度来实现。典型地，该组合式终端设备30可以由一个手机和一个平板电脑组合而成，或者由一个手机和两个平板电脑组合而成。
发明人注意到，当如上描述的由多个移动终端20拼接成一个图2-图5之一所示的组合式终端设备30时，在仅用于显示时或CPU运算能力已经足够时，并不需要拼接的均为具有运算能力的移动终端20，也就是说此时可以将图2-图5之一所示的组合式终端设备30中的一个移动终端20替换为本发明提供的带显示屏的充电宝70，充电宝70仅具有接收外部电力向蓄电池73充电、向显示屏71以及外部设备例如移动终端20供电、以及接收来自外部设备例如移动终端20的显示数据在显示屏71处进行显示的功能，而不具有运算等其它电话功能。由移动终端20向充电宝70提供其显示屏71的显示数据，并且由充电宝70的蓄电池73为移动终端20提供电力。
作为示意性示例，如图11和图13所示的带显示屏的充电宝70，包括显示屏71、位于显示屏71下方的蓄电池73和用于保持显示屏71和蓄电池73的壳体(图中未示出)。充电宝70整体上成形为扁平板状并具有前表面74和背表面75，在拼接的方向上，充电宝70的显示屏71与移动终端20的显示屏10具有相同的宽度或长度。一般地，充电宝70的显示屏71位于前表面74处，在图11中，显示屏71完全提供该前表面74，而在如图13所示实施例中，只有一部分的前表面74由显示屏71提供，但是显示屏71的显示区域的面积和蓄电池73所占区域的面积均不小于前表面74的面积的70％。例如，显示屏71的显示区域的面积不小于前表面74的面积的75％、80％、85％、90％或95％。在本发明的示意性实施例中，显示屏71的显示区域的面积为前表面74的面积的76％、77％、78％、79％、80％、81％、82％、83％、84％、85％、86％、87％、88％、89％、90％、91％、92％、93％、94％、95％、96％、97％或98％。在本发明的一个实施例中，蓄电池73所占区域的面积不小于前表面74的面积的75％、80％、85％、90％或95％。在本发明的示意性实施例中，蓄电池73所占区域的面积为前表面74的面积的76％、77％、78％、79％、80％、81％、82％、83％、84％、85％、86％、87％、88％、89％、90％、91％、92％、93％、94％、95％、96％、97％或98％。该种设置能够在蓄电池73厚度不变的情况下增加蓄电池73的体积，为移动终端20提供更长时间的充电服务，而在充电宝70与手机等移动终端20连接时，该充电宝70的显示屏71能够与移动终端20的显示屏10一起显示。
本充电宝70的一个实施例中，充电宝70在与移动终端20拼接时，一方面为移动终端20提供充电，另一方面充电宝70的显示屏71与移动终端20的显示屏10一起形成为A4纸张比例来显示内容。
在图11和图13所示的本发明实施例中，充电宝70整体上成形为基本上为矩形的扁平板状，以方便与图1所示的基本上为矩形的移动终端20拼接。当然，充电宝70的形状还可以根据与移动终端20拼接的需要来做具体的设计。
本发明的充电宝70具有用于在背表面75处保持移动终端20的设置于壳体上的保持结构。在如图11所示实施例中，保持结构包括邻近于背表面75设置的背侧磁性吸附元件72，背侧磁性吸附元件72用于吸附在移动终端20上设置的对应的背侧磁性吸附元件(例如图8和图9中的磁铁60)，以将移动终端20如图12那样保持在充电宝70的背表面75处。在图13所示实施例中，保持结构包括用于卡持移动终端20的卡扣76，该卡扣76的设置使得充电宝70整体基本为手机壳的形式。如图14所示，当将图13所示充电宝70与移动终端20组合成一个组合式终端设备30时，卡扣76将移动终端20卡接住。此时，充电宝70的背表面75与移动终端20的背表面相抵触，而充电宝70与移动终端20均的前表面的显示屏朝外。将充电宝70与移动终端20数据连接，即可在充电宝70与移动终端20的前表面的显示屏处进行双屏显示。
如上所述，由于本发明的充电宝70能够替换图2-图5之一所示的组合式终端设备30中的一个移动终端20，故充电宝70可以与移动终端20那样设置位于充电宝70两侧的相互平行的第一侧表面和第二侧表面。充电宝70还可以设置在第一侧表面处的第一磁性吸附元件和设置在第二侧表面处的第二磁性吸附元件，用于吸附在移动终端20的侧表面处设置的对应的侧向磁性吸附元件，以便充电宝70的任一侧能够通过吸附来保持移动终端20。第一侧表面和第二侧表面、第一磁性吸附元件和第二磁性吸附元件的设置与上文描述的移动终端20的第一、第二侧表面SL、SR、第一磁性吸附元件和第二磁性吸附元件的设置基本相同，例如第一磁性吸附元件不凸出于第一侧表面，且第二磁性吸附元件不凸出于第二侧表面，详细设置此处不再赘述。
在本发明充电宝70的一个实施例中，第一侧表面处设置第一导电触点，第二侧表面处设置第二导电触点。第一导电触点和第二导电触点用于与由充电宝70保持的移动终端20的侧表面处对应设置的导电触点相互电接触，以提供由移动终端20向充电宝70的数据传输和由充电宝70向移动终端20的放电。在一个优选实施例中，充电宝70的第一导电触点和第二导电触点中的至少一个由弹性材料制成或者被弹簧偏压，使其能够在垂直于其所在的侧表面的方向上移动。例如，第一导电触点有多个弓形金属片组成，第二导电触点凹入第二侧表面，当第一导电触点和第二导电触点与由充电宝70保持的移动终端20的侧表面处对应设置的导电触点相互电接触时，第一导电触点垂直于其所在的侧表面的方向上产生形变来使移动终端20的第二侧表面与移动终端20的侧表面相互对准地贴合。第一导电触点和第二导电触点中的至少一个形成为可在伸出位置和缩回位置之间移动的活动触点：当活动触点处于伸出位置时凸出于其所在的侧表面，活动触点所在的侧表面具有：用于容纳活动触点的凹入部和用于封闭凹入部的可拆卸的触点盖。例如，第一侧表面具有第一凹槽，第一导电触点可旋转地连接于第一凹槽内，第一导电触点能旋出第一凹槽外以与移动终端20的侧表面处对应设置的导电触点相互电接触，以及第一导电触点能向第一凹槽内旋转以断开与移动终端20的侧表面处对应设置的导电触点的电接触。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或 推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
