便携式终端通常包括主机 11和电池 12两部分， 由于在使用过程中， 电池 12需要经常从主机 11上拆卸下来以便充电、 检修或更换， 因此， 电 池 12与主机 11釆取活动式连接。如图 1所示的主机 11的顶端的外侧以及 尾端的内侧均具有槽口朝向侧面的卡槽 111 ,且主机 11上具有容纳电池 12 底部的开口， 安装时， 电池 12自主机 11的尾端沿着开口轴向向前推移， 则电池 12的顶端与主机 11的顶端 4氏触， 同时， 电池 12顶端的两侧具有与 主机 11顶端卡槽 111适配的滑扣 (图 1中未示出）， 电池 12尾端也具有与 主机 11尾端卡槽 111适配的滑扣 121 , 则滑扣 121卡入卡槽 111之后， 电 池 12相对于主机 11无法左右或上下移动； 但电池 12依然可以从主机 11 上沿开口的轴向退出， 因此， 还设有推钮 13结构， 图 1所示主机 11的尾 端具有槽口向上的凹槽， 推钮 13置于凹槽内， 推钮 13的上部具有凸起， 推钮 13与凹槽底部之间设有弹簧， 弹簧不受挤压时， 推钮 13的凸起位于 槽口之上，电池 12尾端在与凸起对应的位置设有槽口向下的凹槽，安装时， 将推钮 13向下按压， 则弹簧受挤压， 凸起进入凹槽内， 不会对电池 12的 滑入造成限制， 电池 12滑入主机 11开口内后， 放开推钮 13 , 推钮 13在 弹簧的弹力作用下向上弹出， 推钮 13的凸起插入电池 12的凹槽内， 从而 可以防止电池 12从轴向上退出。 然而， 现有技术主要釆用推钮 13和弹簧防止电池 12退出， 由于弹簧 的伸缩性能， 电池 12存在松动可能， 从而导致电池 12极片接触不良， 而 且，便携式终端在跌落或撞击时，弹簧在推钮 13的重力或惯性作用下会缩 回， 则推钮 13失效， 电池 12退出； 此外， 现有技术仅仅釆用一小段滑扣 121装入， 稳定性不足。

优选地， 所述主机体的两侧具有沿轴向延伸且槽口朝向两侧的滑槽， 所述电池的两侧具有卡入所述滑槽并沿其轴向滑动的凸棱。
优选地， 所述滑槽位于所述主机体两侧的外侧， 所述凸棱位于所述电 池两侧的内侧。 优选地， 所述电池包括电池本体和装载所述电池本体的壳体， 所述壳 体包括电池面壳和电池底壳， 所述电池底壳位于所述开口部中， 所述凸棱 位于所述电池面壳的侧边， 所述锁定盖的一端抵触所述电池面壳的尾端顶 部。
该发明所提供的便携式终端， 在安装时， 对扭簧施加扭矩， 可以对锁 定盖的一端施力， 则锁定盖相对于推钮翻转， 锁定盖的一端与电池或主机 体之间的纵向距离不再限制推钮的纵向移动， 再推动推钮使其压缩压簧， 则不限制电池底部和主机体底部的贴合， 贴合后， 放开推钮和锁定盖推钮 在压簧的弹力作用下伸出， 与主机体或电池的卡槽卡接， 锁定盖在扭簧的 复位作用下回到初始状态， 则推钮无法从卡槽中退出， 处于顶死状态， 从 而实现电池和主机体在轴向上的双重卡接， 即使便携式设备跌落或受到撞 击， 推钮也不会从卡槽中完全退出， 则推钮依然可以牢靠地锁定电池和主 机体； 拆卸时， 同样翻转锁定盖， 并推动推钮压缩压簧， 使推钮脱离主机 体或电池的卡槽， 则电池可以从主机体的开口部中退出。
在一种具体实施方式中， 推钮的外部可以具有轴向突出部， 锁定盖通 过扭簧与突出部连接， 且在突出部上设置横向转轴， 锁定盖与突出部通过 横向转轴铰接。 由于突出部沿轴向延伸一定距离， 便于锁定盖绕扭簧簧体 的轴线翻转而不受其他结构的限制， 且通过横向转轴铰接可以使双扭簧的 连接更为简单。
在另一种具体实施方式中， 主机体具有位于其两外侧的滑槽， 槽口朝 向外侧， 相应地， 电池的壳体两侧的内侧具有凸棱， 则装配时， 可以将电 池的顶端自主机体的尾端逐渐滑入开口部直至电池的顶端与主机体的顶端 相抵触， 此时， 电池的两侧和主机体的两侧在滑槽的整个轴向长度上均形 成卡接， 能够较为牢靠地在横向和纵向上固定主机体和电池， 而且， 卡槽 位于主机体的外侧， 还可以保护外部灰尘、 水分或其他杂物进入电池与主 机体之间， 从而保证便携式终端设备的使用性能。

具体实施方式
本发明的核心为提供一种便携式终端， 该便携式终端可以牢固固定电 池与主机体， 在便携式终端遇到跌落或撞击等情形时， 电池也不会脱落， 而且电池与主机体的拆装较为方便。
为了使本领域的技术人员更好地理解本发明的技术方案， 下面结合附 图和具体实施例对本发明作进一步的详细说明。
请参考图 4、 图 5、 图 6、 图 7和图 8, 图 4为本发明所提供便携式终 端一种具体实施方式的装配结构示意图； 图 5为图 4所示便携式终端的横 截面示意图； 图 6为图 4所示便携式终端的右视图的尾端部分； 图 7为图 6的结构原理示意图； 图 8为图 4所示便携式终端的结构示意图。
本发明所提供的便携式终端， 包括主机体 21和电池 22, 主机体 21具 有容纳电池 22底部的开口部， 图 8所示的便携式终端仅电池 22底部处于 开口部中。 主机体 21与电池 22在横向和纵向上卡接， 横向即开口部开口 平面上与开口部轴向垂直的方向， 纵向即与开口部平面垂直的方向， 以图 4为视角， 纵向即便携终端的上下方向， 比如， 在主机体 21顶端和尾端的 两侧加工出槽口朝向侧面的卡槽，电池 22顶端和尾端的两侧可以加工出插 入卡槽的结构， 则电池 22可以自主机体 21的后端推入开口部， 且相对于 主机体 21无法左右上下移动（横向和纵向卡接），电池 22置于开口部中后， 其顶端与主机体 21 的顶端抵触 , 则电池 22仅可以沿开口部从主机体 21 的尾端退出。主机体 21可以设有沿纵向移动的推钮 24且与推钮 24之间设 有压簧 27 , 电池 22可以具有槽口沿纵向延伸的卡槽， 则主机体 21通过推 钮 24和卡槽与电池 22在轴向上卡接， 当然， 也可以如图 5和图 6所示， 电池 21的尾端具有沿纵向移动的推钮 24且与推钮 24之间设有压簧 27, 推钮 24的下端插入主机体 21的卡槽中， 则电池 22由于推钮 24限制而无 法沿开口部的轴向退出；拆卸电池 22时，上推推钮 24,压簧 27受压缩回， 推钮 24下端脱离主机体 21卡槽，则电池 22的轴向移动不受推钮 24限制， 电池 22可以从开口部中退出，安装时，上推推钮 24至电池 22装入开口部 后， 放开推钮 24, 推钮 24由于压簧 27的复位作用下移， 则推钮 24的下 端卡入主机体 21尾端的卡槽中， 电池 22无法退出。
便携式终端进一步包括锁定盖 25 , 锁定盖 25与推钮 24之间设有扭簧
23 , 优选推钮 24的外侧与锁定盖 25之间设置扭簧 23 , 推钮 24的外侧即 装配后推钮 24面向外侧的部分， 则对扭簧 23施加扭矩时，推钮 24相对于 锁定盖 25可以绕扭簧 23簧体轴线转动，且扭簧 23未受力矩作用而处于复 位状态时， 锁定盖 25的一端与置有压簧 27的电池 22或主机体 21之间的 纵向距离小于推钮 24插入卡槽中的距离， 如图 7所示， 压簧 27设置于电 池 22的尾端， 锁定盖 25的上端在扭簧 23的复位时与电池 22尾端抵触， 则与锁定盖 25连接的推钮 24不可以向上移动， 推钮 24的下端与主机体 21卡槽底部 4氏触， 推钮 24也无法向下移动， 则推钮 24处于刚性的顶死状 态， 实际上，锁定盖 25的上端在扭簧 23的复位时并不必须与电池 22的尾 端 4氏触 ,锁定盖 25上端与电池 22尾端的纵向距离小于推钮 24插入主机体 21卡槽中的距离即可， 即推钮 24可以上移一小段距离， 但是推钮 24却不 会从主机体 21卡槽中退出。
安装时， 对扭簧 23施加扭矩， 可以对锁定盖 25的一端施力， 则锁定 盖 25相对于推钮 24翻转，锁定盖 25的一端与电池 22或主机体 21之间的 纵向距离不再限制推钮 24的纵向移动， 再推动推钮 24使其压缩压簧 27, 则不限制电池 22底部和主机体 21底部的贴合，贴合后 ,放开推钮 24和锁 定盖 25 , 推钮 24在压簧 27的弹力作用下伸出， 与主机体 21或电池 22的 卡槽卡接， 锁定盖 25在扭簧 23的复位作用下回到初始状态， 如图 7所示 的锁定盖 25重新抵触电池 22的尾端，则推钮 24无法移动，处于顶死状态， 从而实现电池 22和主机体 21在轴向上的双重卡接， 即使便携式设备跌落 或受到撞击， 推钮 24也不会从卡槽中完全退出， 则推钮 24依然可以牢靠 地锁定电池 22和主机体 21 ; 拆卸时， 同样翻转锁定盖 25 , 并推动推钮 24 压缩压簧 27, 使推钮 24脱离主机体 21或电池 22的卡槽， 则电池 22可以 从主机体 21的开口部中退出。
请参考图 9, 图 9为本发明所提供便携式终端另一种具体实施方式中 推钮与锁定盖配合的结构示意图。
推钮 24的外部可以具有轴向突出部 241 , 锁定盖 25通过扭簧 23与突 出部 241连接。 由于突出部 241沿轴向延伸一定距离，便于锁定盖 25绕扭 簧 23 簧体的轴线翻转而不受其他结构的限制。 进一步可以在突出部 241 上设置横向转轴 26, 锁定盖 25与突出部 241通过横向转轴 26铰接， 则双 扭簧 23的连接更为简单。
如图 9所示，锁定盖 25可以具有两个分别位于突出部 241两侧的夹臂 , 转轴 26贯穿两个夹臂以及突出部 241 ; 扭簧 23为双扭簧， 位于双扭簧一 侧的两个簧臂分别抵触两个夹臂， 双扭簧另一侧的簧臂连接推钮 24, 如图 4所示， 可以在推钮 24中间部位加工出横向并列设置的两个轴向通孔， 则 双扭簧 23的横向簧臂可以位于推钮 24的内侧， 与之相对的两个簧臂位于 推钮 24的外侧， 从而抵触位于推钮 24外侧锁定盖 25的两个夹臂， 此外， 轴向通孔便于锁定盖 25的翻转， 使锁定盖 25逆时针旋转 90°, 锁定盖 25 的两个簧臂（在本实施例中， 该两个簧臂与电池 22尾端抵触）可以转入推 钮 24的轴向通孔内， 再将锁定盖 25向上推， 带动推钮 24压缩压簧 27, 从主机体 21尾端的卡槽脱离， 此时， 电池 22可以沿开口部轴向退出； 安 装时， 同样使锁定盖 25逆时针旋转 90。并向上推， 电池 22装入开口部后， 松开锁定盖 25 , 推钮 24卡入卡槽内。 当然， 锁定盖 25并不必要旋转 90。， 旋转的弧度仅需满足锁定盖 25不与电池 22或主机体 21抵触且可以使推钮 24缩回即可。 此实施方式中， 锁定盖 25可旋转的幅度较大， 且锁定盖 25 同时充当推压推钮 24的部件， 使双重锁死以及解锁的过程可以连续完成， 操作较为简便， 此外， 该种结构加工简单， 不影响便携式终端的外观。
主机体 21的两侧可以具有沿轴向延伸且槽口朝向两侧的滑槽 211 , 电 池 22的两侧则具有与滑槽 211适配的凸棱 2211 , 即凸棱 2211可以卡入滑 槽 211并沿其轴向滑动， 则安装电池 22时， 可以将电池 22的顶端自主机 体 21的尾端逐渐滑入开口部直至电池 22的顶端与主机体 21的顶端相抵 触， 此时， 电池 22的两侧和主机体 21的两侧在滑槽 211的整个轴向长度 上均形成卡接， 能够较为牢靠地在横向和纵向上固定主机体 21和电池 22。
请参考图 10和图 11 , 图 10为本实用新型所提供便携式终端又一种具 体实施方式中电池与主机体的配合示意图； 图 11为图 10的 C向示意图。
滑槽 211可以位于主机体 21两侧的外侧， 槽口朝向外侧， 相应地， 凸 棱 2211位于电池 22壳体两侧的内侧， 则装配后， 电池 22的上部卡盖于主 机体 21上， 该种结构可以保护外部灰尘、 水分或其他杂物进入电池 22与 主机体 21之间， 从而保证便携式终端设备的使用性能。 当然， 也可以在主 机体 21两侧的内侧设置槽口朝内的滑槽 211 , 相应地， 凸棱 2211位于电 池 22两侧的外侧， 同样可以实现本发明的目的。
电池 22可以包括电池本体和装载电池本体的壳体， 电池本体即电源， 壳体可以包括电池面壳 221和电池底壳 222, 如图 4所示， 装配时， 将电 池底壳 222和电池面壳 221卡合连接在一起形成整体， 再沿滑槽 211滑入 主机体 21的开口部， 装配后， 电池底壳 222位于开口部中， 凸棱 2211位 于电池面壳 221的侧边， 锁定盖 25的一端 4氏触电池面壳 221的尾端。
以上对本发明所提供的一种便携式终端进行了详细介绍。 本文中应用 了具体个例对本发明的原理及实施方式进行了阐述， 以上实施例的说明只 是用于帮助理解本发明的方法及其核心思想。 应当指出， 对于本技术领域 的普通技术人员来说， 在不脱离本发明原理的前提下， 还可以对本发明进 行若干改进和修饰，这些改进和修饰也落入本发明权利要求的保护范围内。
