电子元件6高度集成后，电子元件6所产生的热量也容易在一定空间内发生集聚，导致电子元件6温度升高，影响电子元件6的工作性能。例如，用户使用电子设备1进行长时间游戏、播放视频或通话的场景下，电子设备1的电子元件6由于长时间连续工作会产生大量的热量而形成热源。用户可以从电子设备1的外部明显感受到电子设备1温度升高。因此，需要将热量及时从电子设备1内部散失到电子设备1外部，才可以使得电子元件6位置的环境温度处于正常工作温度范围内，保证电子元件6工作稳定。
电池组件7用于向电子设备1提供电能，以保证电子设备1正常工作。例如，电池组件7可以向屏幕组件8提供电能，以使屏幕组件8显示图像信息或完成相应的操作指令，或者，电池组件7可以向主板5提供电能，以保证主板5上的电子元件6正常工作。电池组件7包括电池71和电池保护电路板72。电池71可以是锂离子电池， 例如磷酸铁锂电池。电池71是可以将化学能转变为电能的结构件。电池71包括极性相反的正极耳和负极耳。沿电池盖2的高度方向Y，电池保护电路板72设置于电池71的一侧。电池保护电路板72为具有预定厚度的板状结构。电池保护电路板72用于检测电池71的工作状态，降低电池71发生过充电、过放电、短路或超高温充放电的可能性，从而对电池71形成保护。电池保护电路板72包括保护电路。电池71的正极耳和负极耳可以分别与保护电路焊接，从而实现电池71和电池保护电路板72的电连接。
电子设备1作为日常使用频率较高的产品之一，用户对电子设备1轻薄化或小型化的需求越来越大。轻薄化或小型化的电子设备1可以有效降低用户使用电子设备1的疲劳程度和携带难度。同时，用户对电子设备1的功能也有更多的需求，例如，电子设备1可以包括用于拍照、感光或照明等用途的功能器件，以使电子设备1可以实现多种功能。以功能器件为用于拍照的摄像模组为例，为了获得更好的成像品质，摄像模组的尺寸需要设计的较大，以设置性能更好的光学镜片组或光学传感器。但是，尺寸较大的摄像模组会对电子设备1的厚度形成限制。为了实现电子设备1的轻薄化或小型化，同时也获得好的成像品质，需要在电子设备1的电池盖2上设置用于遮挡或掩饰功能器件的装饰件3，从而在使用功能器件实现相应功能的同时也兼顾电子设备1的外观美观度，也可以将功能器件之外的部分的厚度设计的更小，实现电子设备1的轻薄化或小型化。装饰件3设置于电池盖2并可以与电池盖2相连。由于装饰件3的一部分会高出电池盖2的外表面，因此电子设备1上设置装饰件3的区域整体厚度相对较大。电池盖2的外表面指的是朝向外部环境的表面。用户使用电子设备1时可以观察或接触到电池盖2的外表面。
随着对电子设备1的功能需求多样化，使得功能器件的类型和数量越来越多。装饰件3的尺寸大小、各个器件的布局合理性以及电池71的容量大小三者相互限制、相互影响。例如，在保证器件的布局合理性前提下，装饰件3的尺寸增大会导致电池71尺寸缩小，从而会导致电池71的容量下降。电子设备1内部空间较为狭小，因此设置数量较多的功能器件时需要同时考虑电池71的容量大小以及主板5位置和大小等因素。
另外，功能器件自身运行工作中会散发热量。由于功能器件集中设置于与主板5相对应的区域上，因此功能器件会占用更多的主板5和电池盖2之间形成的空间，从而一方面，功能器件占用了更多的空间，会侵占主板5的散热通道，对主板5的散热效率造成不良影响；另一方面，功能器件自身会散发热量，也可以对主板5的散热造成不良影响。这样，如果主板5的热量不能及时地散发出去，热量会在主板5区域发生集聚，导致主板5处于温度较高的工作环境，从而主板5的运行稳定性会下降，进而影响电子设备1的整体运行稳定性。
本申请实施例的电子设备1，对电池保护电路板72和装饰件3之间的空间进行利用，以使功能器件可以设置在主板5以外的区域，从而可以增大装饰件3的尺寸以容纳更多的功能器件，兼顾各个器件的布局合理性，同时又不影响电池71的容量。
本申请实施例的电子设备1，也可以通过分散设置功能器件，降低功能器件在主板5对应区域的密度，从而有利于降低功能器件对主板5的散热过程造成不良影响的可能性。在适应功能器件数量不断增多的趋势下，也保证主板5具有良好的散热。

参见图4至图6所示，沿电池盖2的厚度方向Z，电池保护电路板72投影形成第一正投影100。示例性地，正投影指的是光线垂直一平整面照射位于平整面前方的物体时，物体在平整面上形成的阴影。沿电池盖2的厚度方向Z，第一装饰部31投影形成第二正投影200。电池保护电路板72形成的第一正投影100和第一装饰部31形成的第二正投影200至少部分重叠。需要说明的是，第一正投影100和第二正投影200至少部分重叠包括第一正投影100和第二正投影200部分重叠，以及，第一正投影100和第二正投影200完全重叠的两种实现方式。参见图5所示，第一正投影100和第二正投影200部分重叠时，第一正投影100和第二正投影200存在相交区域。第一正投影100和第二正投影200完全重叠时，第二正投影200位于第一正投影100内，或者， 第二正投影200的第一正投影100重合。
沿电池盖2的厚度方向Z，第一装饰部31位于电池保护电路板72的一侧。第一装饰部31具有与电池盖2的开孔21相连通的第一通孔3a。第一通孔3a位于电池盖2的开孔21所限定的区域内。第一通孔3a用于透光光线或声音，以使光线或声音可以到达第一功能器件9而被第一功能器件9接收，或者，第一通孔3a用于避让第一功能器件9，以使第一功能器件9的一部分可以插入第一通孔3a。通过第一通孔3a可以观察到第一功能器件9。第二装饰部32位于电池保护电路板72远离电池71的一侧。第二装饰部32沿电池盖2的厚度方向Z的正投影与电池保护电路板72形成的第一正投影100不相交，即第二装饰部32沿电池盖2的厚度方向Z的正投影位于电池保护电路板72形成的第一正投影100的外侧。第二装饰部32具有与电池盖2的开孔21相连通的第二通孔3b。第二通孔3b位于电池盖2的开孔21所限定的区域内。电子设备1还包括第二功能器件10。第二通孔3b用于透光光线或声音，以使光线或声音可以到达第二功能器件10而被第二功能器件10接收，或者，第二通孔3b用于避让第二功能器件10，以使第二功能器件10的一部分可以插入第二通孔3b。通过第二通孔3b可以观察到第二功能器件10。示例性地，第一功能器件9和第二功能器件10两者的功能可以相同，也可以不同。示例性地，第一功能器件9可以为摄像模组、闪光灯、飞行时间(Time of Flight，TOF)传感器、光线传感器、麦克风或显示屏。其中，飞行时间传感器指的是一种可以发出经调制的近红外光，在遇到被拍摄物体后反射，通过计算光线发射和反射时间差或相位差，来换算被拍摄物体的距离，以产生深度信息的传感器。第二功能器件10可以为摄像模组、闪光灯、飞行时间传感器、光线传感器、麦克风或显示屏。
沿电池盖2的厚度方向Z，第一功能器件9位于电池保护电路板72面向第一装饰部31的一侧。第一功能器件9对应于第一通孔3a设置。参见图7所示，沿电池盖2的厚度方向Z，第一功能器件9投影形成第三正投影300。电池保护电路板72形成的第一正投影100和第一功能器件9形成的第三正投影300至少部分重叠。需要说明的是，第一正投影100和第三正投影300至少部分重叠包括第一正投影100和第三正投影300部分重叠，以及，第一正投影100和第三正投影300完全重叠的两种实现方式。参见图7所示，第一正投影100和第三正投影300部分重叠时，第一正投影100和第三正投影300存在相交区域。第一正投影100和第三正投影300完全重叠时，第三正投影300位于第一正投影100内(参见图8所示)，或者，第一正投影100与第三正投影300重合。第一功能器件9可以利用电池保护电路板72和电池盖2之间的空间，有利于提高电子设备1的内部空间利用率。
本申请实施例的电子设备1，将第一功能器件9设置于电池保护电路板72面向电池盖2的一侧，从而对电池保护电路板72和装饰件3之间的空间进行利用。在对应主板5的区域以及对应电池保护电路板72的区域均可以设置功能器件，有利于在功能器件数量增多的情况下，降低对应主板5的区域设置功能器件的密度，也实现电池组件7、功能器件和主板5布局合理性。第一功能器件9利用的是电池保护电路板72所对应的空间，因此第一功能器件9不会与电池71发生干涉，从而不会对电池71的布局造成影响。在电池71的尺寸不需要减小，电池71的容量不需要降低的情况下，可以 增大装饰件3的尺寸，并且在装饰件3增大的区域设置第一功能器件9，从而降低对应主板5的区域设置功能器件的密度，也保证了电池71具有良好的续航能力。
一种可实现的方式，参见图8所示，电池保护电路板72形成的第一正投影100靠近电池71的边缘与第一功能器件9形成的第三正投影300靠近电池71的边缘具有重合区域。示例性地，第一正投影100靠近电池71的边缘呈直线段，而第三正投影300靠近电池71的边缘也呈与第一正投影100靠近电池71的边缘重合的直线段。另一种可实现的方式，参见图9所示，电池保护电路板72形成的第一正投影100靠近电池71的边缘与第一功能器件9形成的第三正投影300靠近电池71的边缘相切，也即电池保护电路板72形成的第一正投影100靠近电池71的边缘与第一功能器件9形成的第三正投影300靠近电池71的边缘具有一个交点。示例性地，参见图9所示，第一正投影100靠近电池71的边缘呈直线段，而第三正投影300靠近电池71的边缘呈与第一正投影100靠近电池71的边缘相切的圆弧段。因此，第一功能器件9不会超出电池保护电路板72而侵占安装电池71的空间，使得在不影响电池71容量的前提下可以增大装饰件3的尺寸，同时也可以有效利用电池保护电路板72所对应的空间，进一步提高电子设备1内的空间利用率。
另一种可实现的方式，参见图10所示，第一功能器件9形成的第三正投影300位于电池保护电路板72形成的第一正投影100内。电池保护电路板72形成的第一正投影100的边缘与第一功能器件9形成的第三正投影300的边缘之间没有交点。因此，沿电池盖2的高度方向Y，第一功能器件9与电池71之间可以形成缓冲间隙，从而降低第一功能器件9接触到电池71并挤压电池71而导致电池71发生变形或结构损坏的可能性，提高电池71的使用过程安全性。
参见图5和图11所示，沿电池盖2的厚度方向Z，电池71面向电池盖2的表面与电池保护电路板72面向电池盖2的表面之间存在高度差Δh，以在电池保护电路板72面向电池盖2的一侧形成容纳空间99。需要说明的是，高度差Δh指的是以电池盖2的内表面为基准面，沿电池盖2的厚度方向Z进行测量，电池71面向电池盖2的表面至电池盖2的内表面的距离为第一间距，而电池保护电路板72面向电池盖2的表面至电池盖2的内表面的距离为第二间距，其中，第二间距与第一间距之间的差值为高度差Δh。示例性地，相对电池保护电路板72面向电池盖2的表面，电池71面向电池盖2的表面更靠近电池盖2。第一功能器件9的至少部分容纳于容纳空间99，从而可以在不增大电子设备1整体厚度的前提下，在电池保护电路板72面向电池盖2的一侧可以设置尺寸更大的第一功能器件9。由于容纳空间99为第一功能器件9提供了较为充足的安装空间，因此在电池盖2的厚度方向Z上，第一功能器件9可以与电池保护电路板72之间设置缓冲间隙。在电子设备1发生跌落或碰撞时，第一功能器件9存在朝靠近电池保护电路板72的方向发生位移而挤压或撞击电池保护电路板72的风险。第一功能器件9与电池保护电路板72之间的缓冲间隙可以吸收第一功能器件9的位移量，从而降低第一功能器件9与电池保护电路板72发生接触而导致第一功能器件9挤压或撞击电池保护电路板72的可能性，进而降低第一功能器件9挤压或撞击电池保护电路板72导致电池保护电路板72自身发生变形或结构损坏的可能性，或者，降低第一功能器件9挤压或撞击电池保护电路板72而导致电池保护电路板72牵拉电池71 的正极耳和负极耳，从而导致极耳被拉断或者与电池保护电路板72上的保护电路发生脱焊的可能性。
参见图5所示，电子设备1还包括主板5和转接电路板11。主板5上设置有多种类型的电子元件6。主板5设置于电池保护电路板72背向电池71的一侧。沿电池盖2的高度方向Y，第一装饰部31位于主板5面向电池71的一侧。沿电池盖2的厚度方向Z，第二装饰部32对应主板5设置。第二装饰部32位于主板5面向电池盖2的一侧。第二装饰部32具有与电池盖2的开孔21相连通的第二通孔3b。第二通孔3b位于电池盖2的开孔21所限定的区域内。电子设备1还包括第二功能器件10。第二功能器件10对应第二通孔3b设置。第二功能器件10可以直接连接于主板5，从而可以实现第二功能器件10和主板5之间的信息交互。转接电路板11连接第一功能器件9和主板5，从而可以实现第一功能器件9和主板5之间的信息交互。转接电路板11具有延伸部111。延伸部111位于电池保护电路板72和第一装饰部31之间。第一功能器件9与延伸部111相连。相对第一功能器件9直接与主板5连接的方式，采用转接电路板11将主板5外侧的第一功能器件9和主板5通信连接的方式，可以降低主板5的设计复杂度和连接难度，有利于使得电子设备1内部走线合理，提高空间利用率。
示例性地，主板5可以是印制电路板(Printed Circuit Board，PCB)。转接电路板11可以是印制电路板。第一功能器件9的引脚可以与转接电路板11焊接连接，而转接电路板11可以与主板5对应的引脚焊接连接。或者，主板5可以是印制电路板。转接电路板11可以是柔性电路板(Flexible Printed Circuit，FPC)。第一功能器件9的引脚可以与转接电路板11焊接连接，而转接电路板11可以与主板5通过板对板连接器(Board-to-board Connectors，即BTB连接器)实现连接。柔性电路板自身具有良好的变形能力，可以充分利用狭小空间完成走线布局，因此转接电路板11采用柔性电路板的方式，可以降低第一功能器件9和主板5实现连接的难度以及有效利用电子设备1内的狭小空间，以此提高电子设备1内的器件布局合理性和结构紧凑度。
参见图5和图11所示，沿电池盖2的高度方向Y，电池71、电池保护电路板72和主板5排列设置。沿电池盖2的高度方向Y，主板5与电池保护电路板72之间具有第一间隙H1。电池盖2的厚度方向Z与电池盖2的高度方向Y相垂直。主板5连接于中框4。在电子设备1发生跌落或碰撞时，主板5存在朝靠近电池保护电路板72的方向发生位移而挤压电池保护电路板72的风险。主板5与电池保护电路板72之间的第一间隙H1可以吸收主板5的位移量，从而降低主板5与电池保护电路板72发生接触而导致主板5挤压电池保护电路板72的可能性，进而降低主板5挤压电池保护电路板72导致电池保护电路板72自身发生变形或结构损坏的可能性。
电子设备1还包括支架12。支架12位于电池盖2的内侧。电池盖2可以覆盖支架12。主板5与支架12相连，例如，主板5和支架12可以通过紧固件相连。紧固件可以是螺钉或铆钉。支架12可以为主板5提供安装基础。支架12包括承托部121。承托部121位于电池保护电路板72和第一装饰部31之间。
一种可实现的方式，第一功能器件9与承托部121相连，例如，第一功能器件9和承托部121粘接连接。承托部121可以为第一功能器件9提供支撑力，保证第一功能器件9的位置稳定，进一步降低第一功能器件9朝向电池保护电路板72发生位移而 挤压或撞击电池保护电路板72的可能性。
另一种可实现的方式，第一功能器件9和转接电路板11的延伸部111均与承托部121相连。转接电路板11为印制电路板时，转接电路板11的延伸部111和承托部121可以共同为第一功能器件9提供支撑力。示例性地，第一功能器件9和延伸部111各自与承托部121粘接连接。转接电路板11为柔性电路板时，承托部121可以为第一功能器件9和转接电路板11提供支撑力，保证第一功能器件9和转接电路板11的位置稳定，从而有利于降低第一功能器件9发生移动而牵拉柔性电路板导致柔性电路板与第一功能器件9或者主板5发生脱焊、分离的可能性。
示例性地，支架12和中框4可拆卸连接。例如，支架12通过紧固件和中框4相连。紧固件可以是螺钉。
第一功能器件9设置于承托部121面向电池盖2的一侧。沿电池盖2的厚度方向Z，承托部121和第一功能器件9堆叠设置。或者，第一功能器件9和延伸部111均设置于承托部121面向电池盖2的一侧。示例性地，沿电池盖2的厚度方向Z，第一功能器件9、延伸部111和承托部121堆叠设置，或者，延伸部111位于第一功能器件9的一侧，并且沿电池盖2的厚度方向Z，承托部121和第一功能器件9堆叠设置，并且承托部121和延伸部111堆叠设置。承托部121可以在第一功能器件9面向电池保护电路板72的一侧为第一功能器件9提供支撑，从而有利于进一步降低第一功能器件9朝电池保护电路板72发生移动的可能性。
参见图11所示，支架12的承托部121与电池保护电路板72之间具有第二间隙H2。承托部121为悬臂结构，不与电池保护电路板72接触。在电子设备1发生跌落或碰撞时，承托部121存在朝靠近电池保护电路板72的方向发生变形而挤压电池保护电路板72的风险。承托部121与电池保护电路板72之间的第二间隙H2可以吸收承托部121的变形量，从而降低承托部121与电池保护电路板72发生接触而导致承托部121挤压电池保护电路板72的可能性，进而降低承托部121挤压电池保护电路板72导致电池保护电路板72自身发生变形或结构损坏的可能性，或者，降低承托部121挤压电池保护电路板72而导致电池保护电路板72牵拉电池71的正极耳和负极耳，从而导致极耳被拉断或者与电池保护电路板72上的保护电路发生脱焊的可能性。
参见图5和图11所示，沿电池盖2的高度方向Y，承托部121与电池71之间具有第三间隙H3。在电子设备1发生跌落或碰撞时，承托部121存在朝靠近电池71的方向发生位移而挤压电池71的风险。电池71受到承托部121挤压时，电池71存在外壳破裂导致电解液发生泄漏的风险，或者，电池71受到承托部121挤压时，电池71的正极耳和负极耳存在发生短路的风险。承托部121和电池71之间的第三间隙H3可以吸收承托部121的位移量，从而降低承托部121和电池71发生接触而导致承托部121挤压电池71的可能性，进而降低承托部121挤压电池71而导致电池71外壳破裂、电解液发生泄漏或者电池71的正极耳和负极耳发生短路的可能性。
第一功能器件9的一部分位于第一通孔3a内并且与第一通孔3a之间间隙配合。第一功能器件9的一部分插入第一通孔3a内，从而第一功能器件9可以有效利用第一通孔3a的空间，有利于在电池盖2的厚度方向Z上提高结构紧凑性，减小电子设备1的厚度。电子设备1使用环境的温度会发生变化，第一功能器件9或者装饰件3存在 热胀冷缩的情况。第一功能器件9与第一通孔3a之间间隙配合的方式，可以吸收第一功能器件9的膨胀量或者装饰件3的收缩量，降低因第一功能器件9和第一通孔3a贴合紧密而导致在出现热胀冷缩情况时，第一功能器件9承受较大挤压应力而发生结构损坏或发生不可恢复性变形的可能性。
第二功能器件10的一部分位于第二通孔3b内并且与第二通孔3b之间间隙配合。第二功能器件10的一部分插入第二通孔3b内，从而第二功能器件10可以有效利用第二通孔3b的空间，有利于在电池盖2的厚度方向Z上提高结构紧凑性，减小电子设备1的厚度。电子设备1使用环境的温度会发生变化，第二功能器件10或者装饰件3存在热胀冷缩的情况。第二功能器件10与第二通孔3b之间间隙配合的方式，可以吸收第二功能器件10的膨胀量或者装饰件3的收缩量，降低因第二功能器件10和第二通孔3b贴合紧密而导致在出现热胀冷缩情况时，第二功能器件10承受较大挤压应力而发生结构损坏或发生不可恢复性变形的可能性。
本申请实施例中，在电池保护电路板72的一侧设置第一功能器件9，而装饰件3的第一装饰部31对应第一功能器件9设置。为了避免第一装饰部31与电池71发生位置干涉，一种可实现的方式是，装饰件3设置于电池盖2背向电池组件7的外侧，从而第一装饰部31和电池71不存在位置干涉的问题，因此不需要缩小电池71的尺寸来避让第一装饰部31，避免降低电池71的容量而缩短电子设备1的续航时间，同时在不影响电池71容量的情况下，沿电池盖2的高度方向Y，装饰件3的一部分可以延伸到电池71的上方，从而可以增大装饰件3的尺寸。由于第一装饰部31和电池71不存在位置干涉的问题，因此可以在电子设备1内设置尺寸更大的电池71，以此提高电池71的容量，延长电子设备1的续航时间。
参见图11所示，本申请的装饰件3的尺寸大于电池盖2的开孔21尺寸，从而装饰件3的边缘搭接于电池盖2。电池盖2面向装饰件3的表面具有凹槽22。凹槽22沿开孔21的周向延伸。示例性地，凹槽22沿开孔21的周向连续延伸，使得自身呈圆环形或矩形。凹槽22的形状可以与开孔21的形状相同。开孔21位于凹槽22限定的区域内。电子设备1还包括设置于凹槽22内的密封件13。装饰件3和电池盖2连接后，装饰件3覆盖凹槽22，而密封件13处于装饰件3和电池盖2相互搭接的区域。密封件13用于密封电池盖2和装饰件3，从而降低外部水汽或粉尘经过装饰件3和电池盖2的配合区域进入开孔21，再通过开孔21进入电子设备1的内部的可能性。示例性地，密封件13可以为橡胶密封圈或硅胶密封圈。或者，在凹槽22内点胶，装饰件3和电池盖2粘接后，胶水固化形成密封件13。
在一些可实现的方式中，装饰件3面向电池盖2的表面可以设置凹槽22。或者，电池盖2面向装饰件3的表面以及装饰件3面向电池盖2的表面均可以设置凹槽22，并且电池盖2上的凹槽22与装饰件3上的凹槽22相连通。
电子设备1还包括热熔连接件14。装饰件3和电池盖2通过热熔连接件14相连。热熔连接件14的一端与装饰件3连接后，将热熔连接件14的另一端插入电池盖2的连接孔23。在电池盖2的内侧加热热熔连接件14，以使热熔连接件14的端部熔化。待端部重新固化后，完成装饰件3和电池盖2的连接工作。采用热熔连接件14将装饰件3和电池盖2连接后，可以进一步提高装饰件3和电池盖2之间的连接强度，有利 于保证装饰件3和电池盖2之间的连接稳定性，也有利于装饰件3和电池盖2对密封件13保持于稳定地挤压状态。电子设备1工作于温度变化幅度较大的环境中，装饰件3和电池盖2出现热胀冷缩的情况时，热熔连接件14自身的微小变形可以缓冲装饰件3和电池盖2的拉伸应力或压缩应力，从而降低热熔连接件14承受拉伸应力或压缩应力容易断裂而导致装饰件3和电池盖2脱离连接的可能性。示例性地，热熔连接件14的材料可以是塑料。
电池71连接于电池盖2面向电池71的表面。示例性地，电池71可以粘接于电池盖2。例如，可以使用导热胶将电池71粘接于电池盖2，有利于提高电池71的散热效率。沿电池盖2的高度方向Y，电池71位于开孔21所限定的区域之外。电池71可以不越过电池盖2形成开孔21的表面而延伸至开孔21的下方，从而沿电池盖2的厚度方向Z，从电池盖2的外侧进行观察时，通过开孔21观察不到电池71。沿电池盖2的厚度方向Z，电池71投影形成第四正投影400。参见图6所示，沿电池盖2的高度方向Y，装饰件3的第一装饰部31超出电池保护电路板72靠近电池71的边缘，使得第一装饰部31形成的第二正投影200和电池71形成的第四正投影400部分重叠，即第一装饰部31形成的第二正投影200和电池71形成的第四正投影400存在相交区域。
在一些可实现的方式中，电池71设置于中框4并且与电池盖2之间具有间隙。该间隙内可以用于设置柔性电路板等器件。
本申请实施例的装饰件3示例性地显示为矩形并且位于电子设备1的上半部分的中间位置。在其他可实现的方式中，装饰件3的形状可以是圆形或边数大于4的多边形。装饰件3的位置可以位于电子设备1的上半部分的左边区域或者右边区域，或者，装饰件3占用上半部分的70％至90％的区域。
本申请实施例的电池保护电路板72面向电池盖2的一侧设置的第一功能器件9的数量可以是一个，也可以是两个以上，这里不做限定。
