具体实施方式
下面详细描述本公开的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
下文的公开提供了许多不同的实施例或例子用来实现本公开的不同结构。为了简化本公开的公开，下文中对特定例子的部件和设置进行描述。当然，它们仅仅为示例，并且目的不在于限制本公开。此外，本公开可以在不同例子中重复参考数字和/或字母。这种重复是为了简化和清楚的目的，其本身不指示所讨论各种实施例和/或设置之间的关系。此外，本公开提供了的各种特定的工艺和材料的例子，但是本领域普通技术人员可以意识到其他工艺的可应用于性和/或其他材料的使用。
相关技术中的一些终端设备在充电时，电流从充电接口先到达副板，然后再通过柔性电路板从副板输送至主板，之后再通过另一个柔性电路板从主板输送至充电电池，充电路径较长，当这些终端设备提高充电功率(例如采用加大电流的方式进行快速充电)时，由于电流的流经路径较长，且电流的流量较大，从而则很容易造成电流损耗，致使终端设备在充电时的发热量增大，降低充电效率，同时，电池保护板发热严重易损，还可能烧损终端设备，甚至引发安全事故，例如造成终端设备起火、充电电池爆炸等危险。
为了解决上述技术问题，相关技术中指出，可以尽量减少各个器件通路阻抗，例如，增大充电接口的面积、加宽两个柔性电路板，加宽主板走线、增大充电电池连接器的接口面积等，然而，这些方法只能较小程度地改善充电发热问题。因此，为了更加有效地改善充 电发热问题，本公开提出了一种终端设备100。
下面，参照附图，描述根据本公开实施例的终端设备100。需要说明的是，根据本公开实施例的终端设备100的类型不限，可以是各种内置有充电电池，并能够从外部获取电流对该充电电池进行充电的设备，例如，手机、平板电脑、计算设备或信息显示设备等。
如图1所示，终端设备100可以包括：第一电路板1和充电电池2，第一电路板1上具有充电接口11和电池保护电路12，充电电池2与电池保护电路12相连。也就是说，充电接口11和电池保护电路12都集成在同一块电路板、即第一电路板1上，从而在充电接口11与电源(例如可以固定电源或移动电源)相连时，电流可以直接从第一电路板1到达充电电池2，进而有效地缩短了电流传输路径，降低电流损耗，降低终端设备100在充电时的发热量，提高终端设备100的充电效率，避免烧损终端设备100，降低安全事故隐患，提高终端设备100的充电安全性。
简言之，根据本公开实施例的终端设备100，通过将电池保护电路12集成在设置有充电接口11的第一电路板1上，使得充电电池2不再具有单独的电池保护板，从而可以极大程度地减小从充电接口11到充电电池2的通路阻抗，当高功率大电流快速充电时，能够极大地减少路径发热，改善终端设备100整机的温升表现，提高终端设备100的充电安全性。
此外，需要说明的是，在本公开的实施例中，充电接口11的具体类型不限，例如可以是、但不限于：Mini USB接口、Micro USB接口、Type-C接口、Lighting接口中的一种。此外，可以理解的是，对于终端设备100来说，电池保护电路12的功能和概念为本领域技术人员所熟知，即主要是针对可充电电池(一般指锂电池)起保护作用，避免可充电电池发生被过充、过放、过流、短路及超高温充放电等安全问题。
在本公开的一些实施例中，充电电池2包括一个或者多个电芯20，每个电芯20均具有正极耳201和负极耳202，充电电池2中的至少一个正极耳201和至少一个负极耳202位于充电电池2的靠近第一电路板1的一侧且连接(例如直接焊接)至电池保护电路12，也就是说，充电电池2所包括的全部正极耳201和负极耳202中的至少一个正极耳201和至少一个负极耳202靠近第一电路板1设置。
由此，通过将与电池保护电路12连接(例如直接焊接)的正极耳201和负极耳202设在充电电池2的靠近第一电路板1的一侧，从而可以缩短与电池保护电路12连接(例如直接焊接)的正极耳201和负极耳202的长度，进而可以进一步缩短充电电流的传输路径，降低电流损耗，降低终端设备100在充电时的发热量，提高终端设备100的充电效率，避免烧损终端设备100，降低安全事故隐患，提高终端设备100的充电安全性。此外，通过将 正极耳201和负极耳202连接(例如直接焊接)至电池保护电路12，可以有效地降低连接难度，提高电流传输的可靠性。
需要说明的是，“某极耳设在充电电池2的靠近第一电路板1的一侧”，指的是：充电电池2包括面对第一电路板1设置的预设表面，某极耳由预设表面朝向第一电路板1的方向抽出。例如在图1所述的示例中，当第一电路板1位于充电电池2的下方时，全部正极耳201和负极耳202均由充电电池2的下端向下抽出，从而全部正极耳201和负极耳202均位于充电电池2的靠近第一电路板1的一侧。
在本公开的一些实施例中，如图1所示，充电电池2包括第一电芯21，第一电芯21的正极耳201和负极耳202均位于充电电池2的靠近第一电路板1的一侧且连接(例如直接焊接)至电池保护电路12。由此，第一电芯21可以独立连接于电池保护电路12，从而简化结构。
需要说明的是，当充电电池2包括第一电芯21时，充电电池2可以仅包括一个第一电芯21(例如图1所示示例)，充电电池2还可以包括多个第一电芯21，例如在图2所示的示例中，充电电池2可以包括并联设置的多个第一电芯21，其中每个第一电芯21的正极耳201和负极耳202均位于充电电池2的靠近第一电路板1的一侧且连接(例如直接焊接)至电池保护电路12，从而可以提升终端设备100的蓄电量，且方便连接。
此外，需要说明的是，充电电池2可以仅包括若干个第一电芯21，而不包括其他电芯20(例如图1和图2所示)，充电电池2还可以在包括若干个第一电芯21的同时，还包括其他类型的电芯20(图未示出该示例)。
在本公开的一些实施例中，如图3所示，充电电池2包括第二电芯22和第三电芯23，第二电芯22的正极耳201和第三电芯23的负极耳202均位于充电电池2的靠近第一电路板1的一侧且连接(例如直接焊接)至电池保护电路12，第二电芯22的负极耳202和第三电芯23的正极耳201均位于充电电池2的远离第一电路板1的一侧且相连。由此，可以提升终端设备100的蓄电量，且方便连接。需要说明的是，第二电芯22的负极耳202和第三电芯23的正极耳201可以通过导电金属24直接相连(例如图3所示)、也可以通过电芯20间接相连(图未示出该示例)。
此外，由于第二电芯22的正极耳201和负极耳202分别位于充电电池2的两侧，从而可以避免由于正极耳201和负极耳202均位于第二电芯22的同侧需要一定安全距离，导致第二电芯22的尺寸较大的问题，例如当第二电芯22的正极耳201和负极耳202分别位于第二电芯22的上下两侧时，可以减小第二电芯22在左右方向上的宽度。同样，由于第三 电芯23的正极耳201和负极耳202分别位于充电电池2的两侧，从而可以避免由于正极耳201和负极耳202均位于第三电芯23的同侧需要一定安全距离，导致第三电芯23的尺寸较大的问题，例如当第三电芯23的正极耳201和负极耳202分别位于第三电芯23的上下两侧时，可以减小第三电芯23在左右方向上的宽度。
由此，使得充电电池2可以包括更多数量的电芯20，提高终端设备100的续航能力，或者在不设置更多电芯20的情况下，可以节约终端设备100内更多的空间，从而使得终端设备100内可以有空间设置更多的功能元件，从而在保证终端设备100结构紧凑性的前提下具备更多的功能。
例如在图3所示的示例中，第二电芯22和第三电芯23沿第一方向F1依次排列，第二电芯22的正极耳201和负极耳202分别位于第二电芯22在第二方向F2上的两侧，且第二电芯22的正极耳201和负极耳202在第一方向F1上的间距小于等于3mm(例如0mm、或1mm、或2mm、或3mm)，第三电芯23的正极耳201和负极耳202分别位于第三电芯23在第二方向F2上的两侧，且第三电芯23的正极耳201和负极耳202在第一方向F1上的间距小于等于3mm(例如0mm、或1mm、或2mm、或3mm)。
由此，可以缩小第二电芯22和第三电芯23在第一方向F1上的宽度，从而增大充电电池2在电芯20宽度方向上所排列的电芯20数量，进而可以有效地提高充电电池2的总蓄电量。需要说明的是，第一方向F1可以为终端设备100的宽度方向，第一方向F1还可以为终端设备100的长度方向等等。需要说明的是，第二方向F2可以为垂直于第一方向F1的方向，例如当第一方向F1为终端设备100的宽度方向时，第二方向F2可以为终端设备100的长度方向。但是不限于此，例如在其他实施例中，第二方向F2还可以与第一方向F1相交或平行等。另外，在一些实施例中，第一方向F1和第二方向F2还可以均垂直于充电电池2的厚度方向，充电电池2的厚度方向可以为终端设备100的厚度方向。
需要说明的是，多个电芯20中的每个电芯20的结构形状、结构尺寸均相同，从而方便统一化成产和装配，提高了生产效率。当然，本公开不限于此，多个电芯20中的每个电芯20的结构形状、结构尺寸还可以均不相同，从而可以满足不同的生产要求。
需要说明的是，根据本公开实施例的充电电池2所包括的电芯20的数量不限。可以根据需要具体设置，例如可以为下述三个示例、但不限于下述三个示例。例如在图1所示的示例中，充电电池2包括一个电芯20(即单电芯充电电池)，且该电芯20为第一电芯21；又例如在图2所示的示例中，充电电池2包括两个电芯20(即双电芯充电电池)，两个电芯20均为第一电芯21(此时两个第一电芯21可以分别倒置，以使四个极耳均朝下且连接(例 如直接焊接)至下方的电池保护电路12)；再例如在图3所示的示例中，充电电池2包括两个电芯20(即双电芯充电电池)，两个电芯20分别为第二电芯22和第三电芯23(此时每个电芯20的上下两端可以分别抽出一个极耳，上方的两个极耳通过导电金属24相连，下方的两个极耳连接(例如直接焊接)至下方的电池保护电路12)。
在本公开的一些实施例中，如图3所示，终端设备100还包括：第二电路板3，第二电路板3上具有射频处理电路31、基带处理电路32和应用处理器电路33中的至少一个，第二电路板3与第一电路板1电连接。由此，当充电电池2供电时，充电电池2可以通过第一电路板1与第二电路板3的电连接向第二电路板3供电。
需要说明的是，第一电路板1和第二电路板3可以分别与充电电池2具有不同的相对位置关系，但是，第二电路板3和第一电路板1可以分别为两块电路板(例如图1-图4所示)，也可以为同一块电路板的不同部分(例如图5所示)，当第一电路板1和第二电路板3的相对位置关系确定后，可以具体选择第一电路板1和第二电路板3的电连接方式。
例如在图3所示的示例中，第二电路板3和第一电路板1为分别两块电路板，且第二电路板3和第一电路板1沿第二方向F2间隔开，充电电池2在第二方向F2上位于第一电路板1和第二电路板3之间。由此，可以优化终端设备100内部的空间排布。此时，如图3所示，第二电路板3和第一电路板1可以通过柔性电路板4相连(即对第二电路板3的供电可以通过柔性电路板4连接第一电路板1和第二电路板3实现)，例如在一些示例中，可以将柔性电路板4设置在充电电池2的厚度一侧，也就是说，将柔性电路板4与充电电池2沿充电电池2的厚度方向叠置，从而可以加大充电电池2的容纳空间，进而加大充电电池2的体积和能量密度，提升终端设备100的待机时长。
当然，本公开不限于此，例如图4所示，当第二电路板3和第一电路板1沿第二方向F2间隔开，充电电池2在第二方向F2上位于第一电路板1和第二电路板3之间时，第二电路板3和第一电路板1还可以通过位于充电电池2在第一方向F1上的一侧的硬质电路板5相连，从而满足不同的实际要求。
此外，在本公开的一些实施例中，第一电路板1和第二电路板3也可以均为硬质电路板5。其中硬质电路板5的基材可以为但不限于FR4，柔性电路板4的集采可以为但不限于PI。
另外，在本公开的一些实施例中，第一电路板1除了具有充电接口11、电池保护电路12之外，还可以具有充电控制电路13，其中充电控制电路13的概念为本领域技术人员所熟知，例如充电控制电路13可以至少包括转换电路或直充MOS管等，从而在充电时，电源(固定电源或移动电源)的电流可以从充电接口11经转换电路或直充MOS流入充电电 池2，从而可以进一步缩短充电路径，降低终端设备100整体的设计难度。
当然，本公开不限于此，在本公开的其他实施例中，充电控制电路13还可以包括其他元器件等，且充电控制电路13除了设置在第一电路板1上之外，还可以设在第二电路板3上，或者一部分设置在第一电路板1上、其余部分设置在第二电路板3上等等。
此外，根据本公开实施例的终端设备100的其他构成以及使用方法，在终端设备100的类型具体确定后，本领域技术人员可以知晓，例如，当终端设备100为手机时，终端设备100还可以包括存储器、输入单元、无线保真模块、显示单元、传感器、音频电路、投影单元、拍摄单元等部件，这里不作赘述。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本公开的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不必须针对的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任一个或多个实施例或示例中以合适的方式结合。此外，在不相互矛盾的情况下，本领域的技术人员可以将本说明书中描述的不同实施例或示例以及不同实施例或示例的特征进行结合和组合。
尽管已经示出和描述了本公开的实施例，本领域的普通技术人员可以理解：在不脱离本公开的原理和宗旨的情况下可以对这些实施例进行多种变化、修改、替换和变型，本公开的范围由权利要求及其等同物限定。
