为了使发明的目的、 技术方案和优点更加清楚， 下面将结合本发明实施 例中的附图， 对本发明实施例中的技术方案进行清楚、 完整地描述， 显然， 所描述的实施例是发明一部分实施例， 而不是全部的实施例。 基于本发明中 的实施例， 本领域普通技术人员在没有做出创造性劳动的前提下所获得的所 有其他实施例， 都属于本发明保护的范围。
如图 1至图 6所示， 本发明提出一种智能手机滑轨分离式背夹电源实施 例。
该智能手机滑轨分离式背夹电源包括： 与智能手机配合的保护套 1 和与 该保护套 1配合的电池包 2，该电池包包括上盖 21和与上盖 21卡合固定的下 盖 24， 在该上盖 21与下盖 24之间设有电池 23和与电池 23连接的充放电控 制电路板 26，该充放电控制电路板 26上还固定有与移动终端充电接口配合的 端子部件 25， 在半合围状的下盖 24长度方向两侧壁相对设有导向条 242， 即 在两侧壁 244上分别设有导向条 242，在该保护套 1长度方向两侧分别设有至 少一与导向条 242配合的固定槽 11。
使用时， 将所述保护套与智能手机配合， 电池包通过导向条与保护套上 的固定槽配合进行固定， 该电池包上连接电池和充放电控制电路板的端子部 件与移动终端充电接口配合连接， 实现对智能手机进行充电； 用户不使用时， 可以将电池包从保护套上分离。 由于在供电时， 电池包通过保护套与智能手 机形成一体结构， 当不需要供电时可以方便将其与智能手机分离， 结构紧凑， 体积小巧， 方便使用和携带。 具体地说， 所述上盖 21设有固定卡扣 211， 在 该固定卡扣 211与下盖边缘的卡合部件 241卡合固定， 通过固定卡扣 211与 卡合部件 241配合， 其装配部件少， 提高装配效率。
所述上盖 21与下盖 24固定后， 由下盖 24的两侧壁和设于两侧壁之间的 收纳部 245形成半合围状态， 在两下盖侧壁上分别设有导向条 242。
所述保护套 1为合围结构， 在其长度方向两端分别设有开口 12， 该开口 12的两边分别沿宽度方向向内设有与合围壁 14平滑连接的延伸部 13， 该延 伸部 13上设有与固定槽 11平滑连接的导向槽 15。所述导向槽 15可以更好使 导向条 242进入固定槽 11内。 该开口 12和延伸部 13可以节约材料， 用尽可 能少的材料最大限度地对智能手机四周进行保护， 同时还方便用户从开口 12 处将固定在其内的智能手机取出。 所述收纳部 245用于收纳充放电控制电路 板 26上的控制按键， 同时也用于在与带智能手机的保护套 1配合时收纳其端 部， 使保护套 1和智能手机固定更牢靠。
在所述下盖 2长度方向靠近保护套 1入口端的两侧壁 244设有第一台阶 结构 243 , 在智能手机通过保护套 1与电池包 2进行配合固定时，所述保护套 1的周围被侧壁 244和收纳部 245部分包覆，此时保护套 1位于第一台阶结构 243裸露在外部， 当用户需要将保护套 1与电池包 2分离时， 方便从第一台阶 结构 243处夹持保护套 1， 使其与电池包 2分开。
在所述保护套 1的两侧壁可以根据需要设有多个与固定槽 11平行的防滑 槽， 为了结构的美观， 可以将防滑槽的结构设为与固定槽 11—致， 每侧壁的 防滑槽数量可以根据需要进行设置， 优选地， 每侧的防滑槽和固定槽 11总的 数量超过三个。
在所述下盖 24长度方向两侧壁靠近端子部件 25位置设有第二台阶结构 246。 当保护套 1与电池包 2固定时， 保护套 1的两合围壁可以通过第二台阶 结构 246露在外部， 使用时用户的手可以更好地接触到保护套 1上的防滑槽， 避免滑落。 该第二台阶结构 246与第一台阶结构 243配合， 可以以最少的材 料保证与保护套 1 配合固定时的强度， 同时也方便使用时脱落及方便从电池 包上分离。
在本实施例中， 所述固定槽设置在保护套上， 所述导向条设置在电池包 下盖上， 根据需要也可将固定槽设置在电池包下盖上， 而与该固定槽配合的 导向条设于保护套上， 其工作原理及达到的技术效果相同， 不再赘述。 以上实施例仅用以说明本发明的技术方案， 而非对其限制； 尽管参照前 述实施例对本发明进行了详细的说明， 本领域的普通技术人员应当理解： 其 依然可以对前述各实施例所记载的技术方案进行修改， 或者对其中部分技术 特征进行等同替换， 而这些修改或替换， 并不使相应技术方案的本质脱离本 发明各实施例技术方案的精神和范围。
