Description

一种识别不同厚度电池的装置、 方法及电子设备
技术领域
—明 ¾i"T¾ 领域， 尤其涉及一种识 别不同厚度电池的装置、 方法及电子设备。 背景技术
目前， 釆用可循环充电电池作为电源的便携式电子设备， 如移动终端， 笔记本电脑， 平板电脑等的市场需求迅猛发展， 而这些电子设备的功能和应 用越来越多， 这就造成耗电量越来越大， 设备对电池容量的需求越来越大。 但由于现有电池技术的限制， 电池的容量往往与电池的体积成正比。 在设备 的电量持续力和便携性上很难两全， 这就造成很多电子设备配有两套甚至多 套可选电池， 在同一设备电池卡槽中对应不同需求时换用不同容量和体积的 电池。 这样的应用同时带来了一些问题， 如对不同容量电池的识别和电量计 算以及电量显示等问题。
锂电池具有高存储能量、 寿命长、 重量轻和无记忆效应等优点， 已经在 现行便携式设备中得到了广泛的使用。 mAh是电池容量的计量单位， 具体是 电池中可以释放为外部使用的电子的总数， 折合为物理上的标准单位就是库 仑。库仑的国际标准单位为电流乘于时间的安培秒，即 lmAh=0.001安培 *3600 秒 =3.6安培秒 =3.6库仑。
现有的电子设备， 主要有如下三种方法实现电量的计算：
1.直接电池电压监控方法： 直接电池电压监控方法简单易行； 但是该方 法精度较低（20% ) , 且缺乏对电池的有效保护；
2.电池建模方法： 电池建模方法有效地提高电量的测量精度（5% ) , 简 单易用， 无需做电池的初次预估； 但是数据表的建立是一个复杂的过程， 并 且对不同容量或类型的电池的兼容也不好；
3.库仑计检测法： 库仑计可以精确跟踪电池的电量变化， 精度可达 1%; 但是， 库仑计存在电池初次预估的问题， 需要知道额定容量、 当前容量和当 前的电流损耗， 且电流电阻的精度直接影响了电量的精度。
目前， 以库仑计检测法最为准确和有效， 主流的智能手机终端以及平板 电脑等电子设备大多都釆用库仑计检测法， 但是库仑计检测法只能解决固定 容量电池的电量计算和电量显示问题， 对应不同容量的电池， 库仑计检测法 则无法准确计算显示电量。 因此， 如何实现简单、 快捷、 准确的识别不同容 量的电池成为当前需要解决的一个技术难题。

本实施方式提供一种识别不同厚度电池的装置及方法， 具体釆用如下方 案：
所述装置包括卡扣开关， 和控制电路；
当所述电子设备中安装薄电池时， 所述卡扣开关的状态为通； 当所述电 子设备中安装厚电池时， 所述卡扣开关的状态为断；
所述控制电路根据所述卡扣开关的状态， 识别所述电子设备中所安装的 是薄电池还是厚电池。
其中， 所述卡扣开关包括卡扣、 弹簧件和开关器件， 所述卡扣的一侧设 有与电池本体的侧面相接触的弧形接触面， 另一侧设有弹簧件卡槽； 所述弹 簧件分别与所述卡槽及所述开关器件相连接。
较佳的， 卡扣开关的机械部分由一个或多个上表面为弧面下表面为平面 的卡扣 （该卡扣侧面有弹簧部件卡槽） 、 弹簧件、 连接在主板上的开关器件 组成， 该开关器件可以是机械开关或 FPC (柔性电路板）开关。
较佳的， 卡扣开关在电路连接中是作为一个单刀双掷开关， 具有通、 断 两个状态， 状态通是由高电平拉高的状态， 状态断是接地的状态。 卡扣开关 的开关状态是由电池与卡扣开关的相对位置决定的， 卡扣开关的状态信息通 过 GPIO总线反馈给基带芯片， 基带芯片得到状态信息后将不同状态调用对 应的电池信息管理电源管理模块并对电池进行管理。 当终端设备安装薄电池 时， 安装完毕后卡扣弹起， 卡扣开关状态为通， 当终端设备安装厚电池时， 安装完毕后卡扣被压下， 卡扣开关状态为断。
当电池从主板上方放入电池仓时， 电池的一端接触卡扣的上表面， 压迫 弧面受力向侧面缩进电池仓的侧面槽中， 当电池厚度较薄时， 经过厚度的行 程侧面卡扣不再受力而弹出， 开关状态为断； 当电池厚度较厚时， 经过厚度 的行程侧面卡扣仍在较厚电池的行程中进行受力， 而且不会弹出， 开关状态 为通。
较佳的， 连接主板上的开关器件可以釆用多种形式， 可以是机械压触式 开关、 FPC式开关， 触针式开关等等， 根据不同开关形式的选取， 连接方式 也不同， 可以是开关直接焊接在主板上； 主板上设置金属接触点， 开关上的 弹脚压触在接触点上； 或者主板上设置弹脚， 弹脚压触到开关的金属接触点 上等。
下文中将结合附图对本发明的实施例进行详细说明。 需要说明的是， 在 不冲突的情况下， 本申请中的实施例及实施例中的特征可以相互任意组合。
在下述实施例中， 以手机终端为例对本发明的具体实施进行说明， 但本 发明方案并不局限于应用于手机终端， 同样可以应用于笔记本电脑、 平板电 脑等其他电子设备。
如图 la和图 lb所示， 以手机终端为例，描述了同一种电子设备的后壳 3 中分别装配厚度不同的电池： 薄电池 11和厚电池 12的示意图。
图 2示出了本发明实施例的卡扣开关的控制电路示意图。 如图 2所示， 机械开关的基本工作原理为：机械开关内部包含 Sl、 S2、 S3三个工作 pin脚， 一般情况下 pin脚 S3直接作为接地使用， pin脚 S1与 S2根据实际使用情况 确定定义。
本发明实施例中的开关状态主要有两种状态：
状态 1 : S1处于短路接地状态， S2处于悬空状态， 通过一个上拉电阻网 络后， 连接到 GPIO口， S3为机械开关触点， 在 S3未受到触动时， 开关处于 S1与 S2断开状态中；
状态 2: S1处于短路接地状态， S3在受到触动时，将开关 pin脚 S2与 S1 连接， 受到 S3触发后， S2由悬空状态变更到与 S1连接， 处于接地状态， 开 关处于 S1与 S2接触状态中。 该控制电路上只需要一种状态 （高或者低状态） ， 即可实现基带处理芯 片对外围设备的状态控制， 实现相应的功能。 一般情况下 GPIO ( General Purpose Input Output,通用 10口）口处釆用手机中一个常用的模拟电压 AVDD (数值为 2.8V ) , 在 GPIO口上串联一个电阻 Rserial进行上拉处理方式， 同 时预留一个并联电容 Cparallel, 用于滤除一些干扰信号。
当机械开关处于状态 1时， 由于 S2处于悬空状态， 电路上等效为一个无 穷大的电阻， 等效的无穷大电阻与 Rserial构成电阻分压网络， GPIO 口处的 电压与 AVDD电压相同， 此时 GPIO为一个高电平。
当机械开关处于状态 2时， 由于 S2处于接地状态， 电路上等效为一个零 欧姆电阻， 零欧姆电阻与 Rserial构成电阻分压网络时， GPIO 口处的电压为 零， 此时 GPIO为一个低电平。
GPIO口的高低电平两种状态，分别对应厚薄两种电池类型， 因此基带处 理芯片上通过判断此 GPIO 口处的高低电平， 即可判断出电池厚薄类型， 从 而实现不同电量控制。
如图 3所示为以手机终端为例的一种带有卡扣开关识别装置的爆炸图， 手机终端包括主板 4、 前壳 5和后壳 3 , 其中主板 4上设有卡扣开关组件， 后 壳 3设置两个开槽， 卡扣开关组件的卡扣 7通过开槽嵌在后壳 3内， 部分露 出在表面， 卡扣 7的上弧面向上， 卡扣的侧面留有一柱体， 可以插入弹簧 6, 弹簧 6与连接在主板上的开关器件 8相连 (开关器件 8与主板连接方式可以是 焊接、 螺丝固定等方式或多种方式结合)。
当卡扣 7受力时， 侧面压迫弹簧 6, 卡扣的柱体压迫开关器件 8受力按 下； 当卡扣 7不再受力时， 弹簧 6反弹卡扣 7向外， 开关器件 8不再受力， 弹起。 厚薄电池装配时， 均会压到卡扣 7上弧面使其受力向内缩入。
如图 4所示为本发明实施例的卡扣开关的示意图。图中以两个卡扣为例， 其中一个卡扣和主板上的开关器件连接作为检测开关以及固定电池作用， 另 外一个和结构件相连仅作固定电池作用。 卡扣侧面有一柱体， 当卡扣上弧面 收到压力时， 柱体向内压迫弹簧并按压开关器件， 开关器件状态 1改变为状 态 2。 当装好电池开机时， 基带处理芯片检测开关器件状态， 如果为状态 1 , 则基带处理芯片调用薄电池状态信息并对电池进行管理， 如果为状态 2, 基 带处理芯片调用厚电池状态信息并对电池进行管理。
如图 5所示为厚薄电池装配到带有卡扣开关识别装置的装配图， 薄电池 12高度较低， 当开关器件 8经过薄电池的高度行程后不再受力， 卡扣 7卡住 薄电池 12使其不会掉出， 弹簧 6反弹卡扣 7向外弹出， 开关器件 8不受力未 被按下； 厚电池 11高度较高， 当卡扣 7在厚电池 11卡入后一直受力； 卡扣 7 压迫弹簧 6并压下开关器件 8, 开关器件 8受力被按下， 状态改变。 另外， 图 5中以两个卡扣为例， 其中一个和主板上的开关器件连接作为检测开关以 及固定电池作用， 另外一个和结构件相连仅作固定电池作用。
如图 6所示为带有卡扣开关识别装置的手机终端电池的装配示意图。 以 两个卡扣为例的手机终端为例，可以看出，当薄电池 12装配时卡扣 7先缩入， 装配好以后卡扣 7弹出并卡住薄电池 12, 此时开关状态为状态 1 ; 当厚电池 11装配时卡扣 7缩入， 装配好以后， 卡扣 7不会弹出， 此时开关状态为状态
2。
综上所述， 本发明实施例利用简单的控制电路和卡扣开关结合， 提供了 一种准确判断厚薄电池的结构， 开关在担负识别功能的同时可以作为卡扣结 构固定薄电池， 对于不同厚度电池可以使用一套结构件； 同时还可调用相应 的电池信息对其进行管理。 本发明实施例优点在于结构简单， 成本低， 且能 够准确判断出电子设备中的厚薄电池。
以上仅为本发明的优选实施案例而已， 并不用于限制本发明， 本发明还 可有其他多种实施例， 在不背离本发明精神及其实质的情况下， 熟悉本领域 改变和变形都应属于本发明所附的权利要求的保护范围。
