参阅图2，为符合本发明一优选实施例中智能终端的结构示意图。该实施例中，智能终端包括有互相连接的壳体10及显示单元20，壳体10后盖于显示单元20，可将智能终端的外形构成为无缝的设计。在壳体10与显示单元20间，成形有用于容纳智能终端内部元器件的容置空间。在容置空间内，设有对智能终端及显示单元20控制的各电子器件，并均可布设在一主板30上，在主板30的一侧，设置有智能终端的电源，电源与主板30及显示单元20电连接，向主板30及显示单元20供电，同时，主板30上也设有对电源的充电电路及放电电路，用于向电源补充电能或自电源吸取电能，供给给各电子器件。
可以理解的是，若容置空间设置地较厚或较宽，则整个智能终端也将造型地较厚或较宽。因此，在该实施例中，对于主板30及电源的位置布设采用新型的设计。具体地， 在容置空间内设有一框体40，该框体40分别承接智能终端的壳体10及显示单元20(如显示屏)，上部分与显示单元20互相连接，以固定显示单元20的位置，下部分与壳体10固定连接，将壳体10成型为智能终端的外轮廓。在框体40的固定面(面向显示单元20的端面)上，固定面设计为平面或基本整平的平面，并于固定面上并排设置电源及主板30。且电源设计为分体式，包括位置上互相独立的第一电池51及第二电池52，第一电池51与第二电池52与主板30互相电连接，保证电源对主板30的供电。在布设第一电池51与第二电池52时，由于结构上两者为独立，因此，将第一电池51和第二电池52分别设置在固定面上的两侧边处，使得第一电池51和第二电池52间留有空余处。该空余处放置主板30，从而使得主板30位于第一电池51和第二电池52间。这样设置的好处在于，主板30结构的设计更为多元话，若主板30的形状设计为呈长条状(一侧边较窄，一侧边较宽)，则在框体40的固定面上，留给电源可布设的区域更大，第一电池51和第二电池52在固定面上的占比更多时，由于其可被调整地更宽，则在厚度方向上，若以相同的电池容量为计，第一电池51和第二电池52可设计的更薄，从而压缩容置空间的厚度，进一步减薄智能终端的厚度尺寸。
进一步地，第一电池51与第二电池52间的空余空间内，主板30设置在该空余空间的下方，靠近于固定面的位置，其上方空间仍为冗余。因此在该上方空间处，设置有散热组件60。考虑到主板30上的电子器件在使用时易释放出大量热量，热量在消散时，框体40作为与主板30的接触部分之一，由于框体40常为塑料件，消散能力有限。而在主板30的另一侧，主板30与散热组件60接触，主要依靠散热组件60将热量消散。因此，主板30远离于框体40的一面为热源面，散热组件60面向主板30的端面为散热面，散热面与热源面贴合，使得主板30与散热组件60互相贴合，通过接触传导的方式，将自温较高的主板30上的热量传递至散热组件60上。散热组件60吸收到主板30的热量后，逐渐将热量扩散至散热组件60的各处。在散热组件60上远离于主板30并截止的一端，即散热端，通过热辐射的方式将热量消散。由于第一电池51及第二电池52设置在主板30的旁侧，且第一电池51及第二电池52不用作为热源，因此第一电池51及第二电池52的温度相较于主板30或主板30所在空余空间的温度更低。鉴于此，第一电池51和第二电池52更作为对电源散热路径上的冷区使用，则散热组件60的两散热端便分别向第一电池51及第二电池52延伸，散热组件60的热量热辐射至冷区，从而形成自主板30、散热组件60至冷区的散热路径，降低主板30的温度。
通过上述配置，在电源与主板30的堆叠设置上，电源分隔为位置独立电联统一的设计一方面可灵活调整第一电池51、第二电池52的容量，例如，第一电池51和第二电池52的容量和可达4200-4500mAh，另一方面为对电源的快速充电和稳定放电带来可能，同时主板30的中间位置设计，可降低第一电池51和第二电池52的厚度，相较于现有智能终端，在厚度上可降低0.2mm-0.5mm，最终实现智能终端的超薄设计。且对容置空间的进一步利用，散热组件60无需占用某一宽度，通过与第一电池51和第二电池52的并排设计，更进一步地降低了智能终端的厚度。
参阅图3，在一进一步优选实施例中，散热组件60包括第一散热片61及第二散热片62，第一散热片61和第二散热片62均贴设在热源面上，且可优选地完全覆盖热源面，即在热源面的射影方向上，被第一散热片61和第二散热片62完全遮挡。第一散热片61和第二散热片62在靠近部分接触或不接触均可，而在远离于主板30的端面上，第一散热片61向第一电池51延伸直至与第二电池52靠近但不接触，第二散热片62向第二电池52延伸直至与第二电池52靠近但不接触。可以理解的是，第一散热片61和第二散热片62的延伸方向也可参照沿第一电池51、第二电池52和主板30的布设方向。例如，第一电池51及第二电池52沿智能终端的长度方向或宽度方向布设时(第一电池51及第二电池52在长度方向更长或在宽度方向更长)，第一散热片61和第二散热片62的侧边沿 贴近于第一电池51及第二电池52平行设置，同时散热端沿智能终端的长度方向或宽度方向延伸，延伸长度可最高达整个智能终端的长度或宽度。可以理解的是，散热片的长度越长，对外辐射的面积越大，散热效果也将越好。
如图3所示的实施例中，第一散热片61和第二散热片62均设计为一端截止于主板30的侧边，另一端(即散热端)尽可能地延伸，一方面保证散热面积足够，另一方面也保证空余空间内的空气层足够，同时保证了热传递及热辐射的散热效率。
一优选或可选实施例中，第一散热片61及第二散热片62与主板30间夹设有导热元件63，导热元件63作为第三方元件使得第一散热片61、第二散热片62与主板30间接接触。导热元件63的设置，可加速对主板30热量的吸取，降低主板30温度；同时导热元件63又与第一散热片61和第二散热片62接触，加快将热量传递至第一散热片61和第二散热片62的速度。对第一散热片61及第二散热片62成型时，第一散热片61及第二散热片62包括但不限于热板、热管、石墨片等中的任意一种，导热元件63也包括但不限于导热垫、导热膏等中的任意一种。
又一优选或可选实施例中，第一电池51或第二电池52包括有至少一个电芯，且当电芯数量大于或等于2个时，每个电芯均为串联设置。由于电源已成型为第一电池51和第二电池52的分隔设计，则在容量和电流上，可均分至第一电池51和第二电池52。再通过多电芯的设计，进一步将充电时的电流要求分配至各电芯处，从而实现电流可略高的低压充电，降低充电时的发热温度。
参阅图4-图7，针对第一电池和第二电池的分隔设计，在主板对应设计有一套新型的充放电电路，以实现对第一电池和第二电池充电时串联加快充电速度，放电时并联防止大电流冲击的效果。具体地，在主板上设有充电管理电路，该充电管理电路包括：充电管理芯片、电源管理芯片、第一开关S1、单刀双掷开关和第二开关S4，其中单刀双掷开关包括第一动端S2和第二动端S3，单刀双掷开关可在第一动端S2闭合、第二动端S3断开和第一动端S2断开、第二动端S3闭合的状态间切换。
充电管理芯片在外部电源通过电源输入端Vchg连接后用于对第一电池和第二电池的电压和电流进行控制，其一端与电源输入端Vchg连接，另一端分别与电源管理芯片和第二电池连接。电源管理芯片的一端与充电管理芯片及第二电池连接，另一端与系统输出端Vsys连接，用于产生1/2降压电源。第一开关S1的一端与系统输出端Vsys连接，另一端与第一电池连接，且经第一电池的另一端接地。单刀双掷开关的第一动端S2的一端分别与第一开关S1和第一电池的一端连接，另一端与第二电池连接；单刀双掷开关的第二动端S3分别与第二电池和第二开关S4连接。第二开关S4的两端分别与第一电池和第二电池连接，且与第一电池连接的该节点接地。
参阅图4，在智能终端未连接有外部电源，如充电器、移动电源等时，电源输入端Vchg断开，智能终端的处理器将控制第一开关S1和第二开关S4闭合，且单刀双掷开关的第一动端S2闭合，第二动端S3断开，且电源管理芯片关断。此时第一电池和第二电池并联在接地端及单刀双掷开罐的第二动端S2，从而以并联的方式通过系统输出端Vsys向主板供电。由于智能终端正常使用下，第一电池和第二电池呈并联状态，则在遇到大电流冲击时，可由第一电池和第二电池分流，降低瞬间大电流时对系统冲击。
参阅图5，在智能终端通过电源输入端Vchg与外部电源连接时，智能终端判断为用户将使用外部电源对智能终端进行充电，为加快充电速度，将把第一电池和第二电池自并联状态切换至串联状态。具体地，智能终端控制第二开关S4断开，此时第二电池与接地端断开，具有第二电池的充电电路断开，由第一电池单独向主板供电。继而智能终端控制单刀双掷开关断开第一动端S2，转而闭合第二动端S3，激活自电源输入端Vchg、充电管理芯片、第二电池、第二动端S3、第一电池至接地端的充电电路，同时仍保有第一电池经第一开关S1向主板供电的供电电路。可以理解的是，当第一电池和第二电池呈串 联时，外部电源的输入电流可更大，且第一电池和第二电池同时得电，将缩小充电时间。进一步地，智能终端控制电源管理芯片打开，由供电电路除依然保有的第一电池外，还将形成自外部电源、充电管理芯片、电源管理芯片至系统输出端的Vsys另一路供电电路。更进一步地，将断开第一开关S1，即断开具有第一电池的供电电路，启动对第一电池和第二电池的完全充电，对主板的供电，则有电源管理芯片的供电电路实现。上述过程中，在确立电源管理芯片的供电电路前，始终保有第一电池的供电电路，防止系统掉电。
参阅图6在外部电源对第一电池和第二电池持续充电时，仍保持了自接地端、第一电池、第二电池至电源管理芯片的供电电路，即供电也可由串联的第一电池和第二电池经电源管理芯片的1/2降压后实现。
参阅图7，当外部电源，如充电器突然拔出，即电源输入端Vchg与外部电源断开时，在该瞬间下，第一电池和第二电池组成的串联电路仍与电源管理芯片连接，经经电源管理芯片的1/2降压后对主板供电。后智能终端将闭合第一开关S1，实现自接地端、第一电池至系统输出端Vsys的供电电路，即同时第一电池和电源管理芯片同时供电。进一步地，智能终端控制关断电源管理芯片，改由第一电池单一地对主板供电。继而智能终端控制单刀双掷开关的第一动端S2闭合，第二动端S3断开，使得第一电池和第二电池呈并联状态(此时第二电池的供电电路尚未被激活)。最后智能终端控制第二开关S4闭合，使得第一电池和第二电池并联后的供电电路完全激活，同时对主板供电。通过放电时对第一电池和第二电池的同时取电，可实现两个电池在使用时电压和容量不会出现偏差。
上述充放电电路的设计，可实现第一电池和第二电池充电时串联，放电时并联，同时保证快速充电与大负载供电。且在第一电池和第二电池的串并联切换过程中，始终有某一电源向主板供电，不会出现系统掉电的情况。相较于现有单电池或伪双电池的设计，本实施例中的电池管理电路在充电时，可实现对第一电池和第二电池约50～60W的充电功率。同时在第一电池和第二电池并联放电时，不会损失放电效率，相当于提升电池容量，提高智能终端的续航能力。
智能终端可以以各种形式来实施。例如，本发明中描述的终端可以包括诸如移动电话、智能电话、笔记本电脑、PDA(个人数字助理)、PAD(平板电脑)、PMP(便携式多媒体播放器)、导航装置等等的智能终端以及诸如数字TV、台式计算机等等的固定终端。下面，假设终端是智能终端。然而，本领域技术人员将理解的是，除了特别用于移动目的的元件之外，根据本发明的实施方式的构造也能够应用于固定类型的终端。
应当注意的是，本发明的实施例有较佳的实施性，且并非对本发明作任何形式的限制，任何熟悉该领域的技术人员可能利用上述揭示的技术内容变更或修饰为等同的有效实施例，但凡未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何修改或等同变化及修饰，均仍属于本发明技术方案的范围内。
