下面将结合附图以及具体实施例来详细说明本发明， 在此本发明的示意 性实施例以及说明用来解释本发明， 但并不作为对本发明的限定。 实施例 1:
参见图 1-7所示。本实施例提供的一种易于安装的锂离子电池组，主要包 括： 电芯体 101、 以及封装在电芯体 101外的壳体 601。
其中该电芯体 101为由多个锂离子电池单体 1011通过串联或并联或串联 以及并联的组合连接组成。 壳体 601设置在电芯体 101外部， 用于将组合在一起的多个单体 1011封 装在一起形成电芯体 101。 具体地， 壳体 601包括： 位于电芯体 101底部的底板 102、 侧壳 602、 顶 部塑料件 103、 以及塑料件后盖板 104。
其中， 底板 102封装在侧壳 602的底部， 侧壳 602封装在电芯体 101的 四个侧面外周， 侧壳 602将各单体 1011从外周封装在一起。 顶部塑料件 103封装在电芯体 101的顶部。 塑料件后盖板 104封装在顶部塑料件 103的侧面开口部 1031。 底板 102、 侧壳 602、 顶部塑料件 103、 以及塑料件后盖板 104共同组合 将电芯体 101牢牢地密封在内， 得到一个整体的电池组。 在顶部塑料件 103上， 在与顶部塑料件 103的侧面开口部 1031正对的侧 面板的内壁上安装固定有用于供输出接口件 104、以及输入接口件 105贯穿的 输出孔 1041、 1042、 1051 , 输出接口件 104、 以及输入接口件 105分别贯穿 在输出孔 1041、 1042、 1051上， 以便用户从外部通过插入或者旋入外部的输 出引线端子或者外部的电源输入端子实现电源的输出、 以及对本电池组的充 电。
输出接口件 104、输入接口件 105分别固定在电路转接板 106上， 并且与 电路转接板 106上的输出电路、 输入电路分别电路连接。 电路转接板 106与 电芯体 101的输入电路、 输出电路分别电路连接。
另外， 在该电路转接板 106上除了上述的部件以及线路外， 还可以但不 限于进一步根据实际需要设置有电池保护电路以及控制电路等。
在安装时， 可以但不限于采用以下的案件流程： 首先， 将电芯体 101放置于侧壳 602内， 然后在侧壳 602的底部开口处 封堵安装底板 102, 使该底板 102封堵固定在侧壳 602的底部开口处。 然后， 将顶部塑料件 103安装到侧壳 602的顶面开口处。 由于本实施例顶部塑料件 103上一水平侧面设置为开口 （将该开口记为： 侧面开口部 1031 ), 在装配顶 部塑料件 103后， 可以从该侧面开口部 1031处方便地进行电芯体 101的电路 连接安装操作， 譬如包括但不限于： 将输出接口件 104以及输入接口件 105 , 该输出接口件 104、输入接口件 105分别与电路转接板 106上各电路线路分别 焊接连接。
在完成电路连接后， 将塑料件后盖板 104固定封堵顶部塑料件 103的侧 面开口部 1031即可。
在本实施侧壳 602的顶部还设置有一个或者多个垂直的孔位 1071 , 相应 地， 在位于侧壳 602顶部的顶部塑料件 103的底部设置一个或者多个垂直的 顶柱 1032, 各垂直的顶柱 1032分别与垂直的孔位 1071相互正对适配。 当连 接时， 使位于顶部塑料件 103的底部的顶柱 1032分别插入侧壳 602上相应垂 直的孔位 1071内， 直到顶部塑料件 103的底部边缘与侧壳 602的顶部边缘相 互紧密接合为止， 实现侧壳 602与顶部塑料件 103的密封连接。
另夕卜，在塑料件后盖板 104上，在朝向顶部塑料件 103的侧面开口部 1031 的一侧设置有至少两个伸出的顶柱 1041 , 相应地在顶部塑料件 103内分别设 置有至少两个水平的孔部 1033 ,当塑料件后盖板 104的各水平顶柱 1041分别 插在顶部塑料件 103内的各水平孔部 1033内时， 塑料件后盖板 104封装在顶 部塑料件 103的侧面开口部 1031 ,从将顶部塑料件 103的侧面开口部 1031紧 密封住。
由上可见， 应用本实施例技术方案， 该电池组的外壳 601由底板 102、 侧 壳 602以及顶部塑料件 103以及塑料件后盖板 104组成， 其相对于现有技术 中的方形腔体加上面板组成的结构， 采用本实施例技术方案更加便于电池组 的装配， 有利于在生产时提高装配工艺效率。
另外，在本实施例的侧壳 602与顶部塑料件 103的底部之间通过孔位 1071 与顶柱 1032相互卡插连接， 并且顶部塑料件 103与塑料件后盖板 104之间通 过孔位 1033以及顶柱 1041相互卡插连接， 使得壳体 601各个部件的组装连 接更为方便， 并且易于定位安装， 有利于提高安装效率， 并且避免采用螺釘 连接时由于打螺釘导致的刮花或者不良品的产生。
并且， 在本实施例中， 将孔部 1071设置在棱边边缘较长的侧壳 602的长 度方向而不是设置在相对边缘较短的顶部塑料件 103上， 并且将孔部 1033设 置在棱边边缘较长的顶部塑料件 103 上而不是设置在相对边缘较短的塑料件 后盖板 104上， 一方便有利于孔部 1071、 孔部 1033设置的开设， 另一方便有 利于将孔部 1071、 孔部 1033设置的较深而提高其与对应的顶柱 1032以及顶 柱 1041的插入适配深度， 使得连接更加牢固， 不易于移位或者脱落。
另外， 在本实施例中， 在安装时， 在将电芯体 101置于侧壳 602的内腔 后， 可以从侧壳 602的顶部开口对电芯体 101的顶部连接组成电芯体 101的 各单体 1011与电路板的电路连接， 实现各单体 1011 的串并联电路连接， 实 现输出电路、 输入电路的引线连接； 然后在电芯体 101 的顶部安装顶部塑料 件 103 , 从顶部塑料件 103的侧面开口部 1031执行电路板与顶部塑料件 103 上的各输出接口件 104、 输入接口件 105的连接， 使操作方便易于执行， 进一 步提高工艺操作的效率。
在本实施例中，优选但不限于采用金属侧壳 602, 以使与电芯体 101接触 面积最大的侧壳 602有效地将电芯体 101工作过程中散发的热量散发到外部， 有利于提高电芯体 101的散热效率， 特别适合于高倍率电池组。
在本实施例中，优选但不限于采用金属底板 102,使与电芯体 101底部接 触的底板 102可更有效地将电芯体 101工作过程中散发的热量散发到外部， 提高电芯体 101的散热效率， 本实施例结构特别适合于高倍率电池组。 需要说明的是， 本实施例的底板 102与侧壳 601的连接可以采用图 1所 示的螺釘固定连接的方式， 也可以参照侧壳 602与顶部塑料件 103之间的顶 柱与孔部相互插入而固定的方式。 本实施例中， 由于顶部塑料件 103以及塑料件后盖板 104为绝缘， 故可 以选用横截面较大并且中间设置有通孔或者开孔的金属管体作为输出接口件 104、 输入接口件 105 , 将输出接口件 104、 输入接口件 105直接贯穿顶部塑 料件 103 一侧面的壁体。 采用该连接， 一方面方便安装连接， 另一方面有利 于确保电性安全。
作为本实施例的一种应用举例， 设置在侧壳 602顶部的孔部 1071可以为 4个， 相应地， 设置在顶部塑料件 103底部的顶柱 1032为 4个， 使侧壳 602 与顶部塑料件 103的连接在 4个角度均被定位固定， 连接更为紧密、 牢固。
作为本实施例的一种应用举例， 设置在顶部塑料件 103上的孔位 1033可 以但不限于为 5个。 该孔部 1033的设置具体是， 在顶部塑料件 103内腔侧分 别设置与侧面开口部 1031垂直的 5个直棱 1034, 其中四个直棱 1034分别设 置在顶部塑料件 103的四个转角的内侧， 另一个设置在顶部塑料件 103的顶 板的中部， 而在 5个直棱 1034上分别设置有上述的孔部 1033。 相应地， 设置 在塑料件后盖板 104上的顶柱 1041为 5个， 分别插入在顶部塑料件 103的各 孔部 1033。 使顶部塑料件 103与塑料件后盖板 104的连接在四个转角以及一 侧面内侧的中部被定位固定， 使连接更为紧密、 牢固。 在本实施例中， 还可以在顶部塑料件 103 上与侧面开口部相对的侧面面 板的内侧设置一个沿内侧水平突出或者延伸出的水平承载板 1035 , 从而将固 定在顶部塑料件 103 的第一侧面面板上的输出接口件 104、 以及输入接口件 105固定在该水平承载板 1035的上表面，使水平承载板 1035位于输出接口件 104、 以及输入接口件 105的底部对其重力^载的作用。 这样， 一方面可以方 便输出接口件 104、 以及输入接口件 105的安装定位， 另一方面有利于避免在 使用过程中输出接口件 104、 以及输入接口件 105由于输入端子、输出端子的 插拔而移位， 进一步确保结构的稳固、 耐用性。 其中输出接口件 104、 以及输 入接口件 105可以通过螺釘连接或者胶水粘结或者其他连接方式固定在顶部 塑料件 103的水平承载板 1035上表面。
另外， 作为本实施例的进一步应用举例， 可以但不限于在塑料件后盖板 104上设置有 6个顶柱 1041 , 使其中 4个顶柱 1041位于塑料件后盖板 104的 边缘转角处， 另外 2个顶柱 1041位于后盖板的两长度方向的中部， 相应地， 可以在顶部塑料件 103的相应位置设置 6个相应的孔部 1033 , 其中 4个位于 顶部塑料件 103的四个转交位置的内侧， 另 2个位于顶部塑料件 103的两长 度方向的内侧中部， 在 6个顶柱 1041 以及孔部 1033相互匹配后， 该 6个顶 柱 1041 以及孔部 1033被隐藏在内， 顶部塑料件 103与塑料件后盖板 104的 边缘密切的贴合在一起， 使得装配结构更加稳固。
另夕卜， 在本实施例中还可以将本电池组的侧壳 602设置成互相扣合连接 结构,具体是，该侧壳 602由第一扣合侧壳 6021以及第二扣合侧壳 6022组成。 第一扣合侧壳 6021、第二扣合侧壳 6022的一侧面以及两相对端部分别呈槽状， 第一扣合侧壳 6021、第二扣合侧壳 6022的槽状开口分别正对扣合连接在一起 组成一个顶部以及底部开口的侧壳 602。
第一扣合侧壳 6021的顶面覆盖在电芯体 101的第一侧面的外表面， 第一 扣合侧壳 6021 的两侧面分别覆盖在电芯体 101上， 并且第一扣合侧壳 6021 与第一侧面相邻的第三侧面以及第四侧面的上部外表面； 第二扣合侧壳 6022 的顶面覆盖在电芯体 101上与第一侧面相对的第二侧面外，第二扣合侧壳 6022 的两侧面分别覆盖在电芯体 101 上、 与第一侧面相邻的第三侧面以及第四侧 面的下部外表面， 第一扣合侧壳 6021、 第二扣合侧壳 6022在电芯体 101的第 三侧面以及第四侧面的边缘上下相互扣合连接， 从而两类似于槽体形的第一 扣合侧壳 6021、第二扣合侧壳 6022相互在槽体开口上下正对相互扣合组成一 筒状的侧壳 602, 该电芯体 101被固定安装在第一扣合侧壳 6021、 第二扣合 侧壳 6022形成的空间内。 采用上述结构， 在进行电芯体 101的安装时， 可以 方便的将电芯体 101 从槽体开口放置于第一扣合侧壳 6021、 第二扣合侧壳 6022的其中之一内， 然后将另一扣合侧壳安装在该已放置有电芯体 101的扣 合侧壳上， 槽状开口位置上下正对接合即可， 使电芯体 101被方便地封装安 装在由第一扣合侧壳 6021与第二扣合侧壳 6022之间。 第一扣合侧壳 6021与第二扣合侧壳 6022之间的连接具体可以为： 在第一扣合侧壳 6021的槽状开口的两侧的边缘上分别设置有一第一扣合 部； 在第二扣合侧壳 6022的槽状开口的两边的槽状开口的两侧的开口边缘上 分别设置有一第二扣合部； 第一扣合侧壳 6021上的两第一扣合部分别与第二 扣合侧壳 6022 的两第二扣合部分别正对相互扣合连接， 而将第一扣合侧壳 6021、 第一扣合侧壳 6021对接组合在一起形成上述的侧壳 602。

同理， 第二扣合侧壳 6022开口两侧的两边缘上的两第二扣合部优选但不 限于设置为沿各第二扣合部所在的边缘连续并且同长。
如图 1所示， 在第一扣合侧壳 6021的开口的两侧面的外表面上分别设置 有一个与第一扣合侧壳 6021同长的第一凹槽 201以及第一凸棱 202 (该第一 凹槽 201与第一凸棱 202共同组成第一扣合部 ), 其中第一凸棱 202位于第一 凹槽 201外。
同理， 在第二扣合侧壳 6022的开口的两侧面的内侧面分别设置有一个与 第二扣合侧壳 6022同长的第二凹槽 301以及第二凸棱 302 (该第二凹槽 301 与第二凸棱 302共同组成第二扣合部 ), 其中第二凸棱 302位于第二凹槽 301 外。 在进行安装时， 使第一扣合侧壳 6021开口的两侧面的两第一凸棱 202分 别从第二扣合侧壳 6022上的端部分别滑进第二扣合侧壳 6022的两第二凹槽 301内， 直到第一扣合侧壳 6021与第二扣合侧壳 6022相互正对为止。 采用该 连接结构安装方便建议， 且定位准确、 快速。 在本实施例中， 第一扣合侧壳 6021、 第二扣合侧壳 6022的各外表面还可 以设置有散热凸棱， 该散热凸棱可以仅设置在第一扣合侧壳 6021、 第二扣合 侧壳 6022 上开口两侧的两侧面的外表面； 或者还可以设置在第一扣合侧壳 6021、 第二扣合侧壳 6022上与开口相对的顶面的外表面； 或者还可以设置在 第一扣合侧壳 6021、 第二扣合侧壳 6022上的所有侧面的外表面。 采用该散热 凸棱设计可以进一步提高与电芯体 101接触面积较大的侧壳 602的散热效果， 提高电池组的散热效果， 有利于提高锂离子电池组的使用寿命。 以上对本发明实施例所提供的技术方案进行了详细介绍， 本文中应用了 明只适用于帮助理解本发明实施例的原理； 同时， 对于本领域的一般技术人 员， 依据本发明实施例， 在具体实施方式以及应用范围上均会有改变之处， 综上所述， 本说明书内容不应理解为对本发明的限制。
