Description
本申请是本发明的共同发明人Adnan Aksoy和Mark S.Bresin于1992年9月14日提交的、本受让人的未授权的美国申请序号07/944，610、名称为电池组件的部分继续。申请人根据35USC部分120要求发明的优先权。
本发明涉及蓄电池单元电池组件，具体涉及电池组件的结构。
便携式设备如双向无线电设备的电池组件典型地包括多个单元电池，这些电池具有都在一个外壳内焊接在一起的接点。各单元电池使用金属薄片互连，这些金属薄片点焊在电池端部。通常，互连的单元电池再点焊到柔性线路，随后插入一个电池外壳中。这个制造方法是以低效的组装过程和不必要的部件及劳动制造的，导致过大的制造费用和可靠性的下降。
用于消费者电子设备如摄影机、无线电设备、CD描放机等的消费者装入的电池典型地在其一端具有弹簧装入接点，和接到电池相对端的金属接点。消费者装入的电池组件不要求一般可在电池组件中找到的额外电路。便携式无线电设备的电池组件通常包括电阻、热敏电阻、二极管和其它能使该电池组件再充电和/或保持安全的部件。因此，消费者装入的电池室仅可能在外壳上压制了金属，蓄电池单元电池和电路之间的电气衰耗在这些应用中不太重要。
其它电池组件可以是消费者装入的或者是由制造商装入和密封的，典型地包括多个单元电池，它们是热装在一起或者包装在一个塑料壳中。而且，这些单元电池中的许多典型地通过焊接薄片电气连接一起到各个电池的不同的端子(正或负)。随后，焊接的电池热装在一起并且插入一个外壳。而且，这个组装过程是低效的，导致过大的劳动和制造成本。
减少电子消费产品的重量的努力与增加电池组件装配的容易程度或可制造性的努力一样影响着电池组件装配。为此，以较少部件和零件特性的能力在减少组装步骤的数量中是关键性的。据此，需要一种电池组件，该电池组件提供了消费者装入电池组件的方便，减轻了重量，有更高的效率和能够在组装及制造中减少成本。

一个电池组件包括具有一整体的闩锁机构的一个第一外壳部件，可拆卸地装在第一外壳部件的一个框架，插入该框架和第一外壳部件的多个电池，在该框架上的电路，用于连接多个电池并提供充电和电源接点，和一个第二外壳部件，它基本上是层状的并且固定地装在所述第一外壳部件上。
参见图1，它示出一个电池组件的透视图，它在由Mark S.Bresin于1992年3月9日提交的、已转让给本受让人莫托罗拉公司的、申请号为07/848465、名称为无焊接电池组件的美国专利申请中讨论了，因此引用供参考。电池组件10包括具有一个顶部2和一个底部4的一个外壳。外壳这两部分最好做成咬合在一起。可替代地，外壳这两部分也可用超声波焊接在一起。外壳顶部2还包括一个闩锁机构3，它与在底部4中的凹口区5啮合，允许可拆卸的连接电池组件10到无线电设备(未示出)。在外壳部分2和4内，放置有一个框架11(用于保持单元电池12)，它可拆卸地安装在至少一个外壳部分。
参见图2，示出了根据本发明的电池组件100的透视图。电池组件100最好包括一个第一外壳部件104，它具有装入或集成入第一外壳部件104中的一个闩锁机构103。接着，框架111装入第一外壳部件104。该框架最好经过该框架中的沟槽150和外壳部件104中的啮合轨道152咬合入第一外壳部件。可替代地，框架111也可以组合为第一外壳部件104的一部分。另一个选择是用超声波焊接框架111到第一外壳部件104。然后分别具有正端和负端114和113的电池112被定向并插入框架111。最好包括电阻(未示出)、多极开关(30)和热敏电阻(40)的电路装置安装在框架111上提供充电和电源接点，和本领域公知的用于安全充电可再充电电池组件的合适的电路。可替代地，电路装置可包括具有一些部件如电阻、多极开关和热敏电阻的柔性电路，该电路进一步互连该电池。最后，第二外壳部件102最好固定接到第一外壳部件。为了最大地减少重量，第二外壳部件102最好是塑料层压片，如在其内表面上具有粘合剂的聚碳酸脂，以便粘附在第一外壳部件104上。可替代地，第二外壳部件102可用超声波焊接到第一外壳部件104。另外，第二外壳部件102可用作电池组件100的标牌。
参见图3，示出根据本发明的另一个电池组件200。电池组件200包括一个第一外壳202，最好具有整体地形成在第一外壳中的咬合机构204。多个单元电池206最好预先包装为电池组放入并保持在咬合机构204。电池组最好也包括提供单元电池之间进一步互连的柔性电路212、接点和其它所需的部件，如电阻和热敏电阻(未示出)。最后第二外壳部件220放在电池组206的顶部并且咬合到第一外壳部件202。第二外壳部件最好有开口214，用于由该咬合机构204固定。另外，开口216成形在第二外壳部件中，当在柔性电路212上所示接点插入开口216时开口接触这些点。同样地，第一外壳部件202有开口205，允许柔性电路212上所示接触点插入。任选地，通过使用在第一外壳的内侧部分与单元电池包装206的底部之间的双侧粘合剂(208)(如胶带)和使用第二外壳220的内侧部分与电池包装210的顶部之间的双侧粘合剂(207)，可进一步使电池组件220具有整体特性。
参看图4，示出根据本发明的电池组件的第三实施例。该电池组件一般地包括适用于保持单元电池304的蓄电池的基底部分或外壳302。应懂得单元电池304将包括在前面实施例中叙述的任何柔性金属片或电路。为了在外壳302中保持单元电池304，可使用一层或几层粘合剂材料306。例如，粘合剂306可以是胶水或某种形式的双面胶带。粘合层306可用于将单元电池304固定在外壳302中。而且，在该电池顶部可采用另一个粘合层306固定内壳308以便在外壳302内保持单元电池304。
一般地，外壳308适于套在壁310上，壁310一般绕外壳302的周围延伸。壁310、支撑面311和任何粘合剂306可用于防止单元电池304在外壳302内移位。内壳308由模压的热成形塑料材料或某种其它合适的材料构成。最好是，内壳308包括在热成形塑料中整体形成的一个标牌。壁310最好包括一个能量导向体312(在图4的线A—A得到的图5横截面详细地表示)。能量导向体312在超声波焊接技术中采用。特别地，外壳308的肩形部分314可用超声波焊接到能量导向体312。超声焊接可沿整个壁310或在选择的部分根据需要提供。本领域公知的任何超声焊接机构都可使用。
而且，一个固定机构包括放置在壁310基底的周围的多个接片部分316，将内壳308固定到外壳302。沿着脚320的相应容纳部分318包括在外壳308中。闩锁316/容纳部分320的各种实施例参照图6—8详细地叙述。最后，粘附材料可在脚320周围放置。将内壳308固定到外壳302。可以使用粘附剂粘接、超声波焊接和闩锁的任一种或任何组合。
参见图6，它示出固定机构第一实施例的分解图。该固定机构包括一个接头322，一般地它插入凹座324中。例如可使用图6的固定机构在超声波焊接时保持内壳308相对于外壳302的位置。
参见图7，它示出了固定机构第二实施例的分解图。该固定机构包括一个接头部分326，适于卡住外壳308的凹槽328。图6的固定机构也可用于在超声波焊接时保持内壳308相对于外壳302的位置。
最后，参见图8，它示出了固定机构第三实施例的分解图。该固定机构包括一个闩锁330，适于确实地啮合位于外壳308的底脚318内的孔332。特别是，闩锁330包括两部分，它们可被压紧以啮合孔332。但是，应懂得本领域公知的其它类型的闩锁机构可用于确定地啮合上壳。
现在翻到图9，示出了根据电池组件第四实施例的电池组件的透视图。该电池组件通常包括适用于保持单元电池404的蓄电池的一个外壳402。为了在外壳402中保持单元电池404，可在该电池的任一侧上使用粘合材料406。例如，粘合材料406可以是胶水或某种形式的双面胶带。最后，包括一个内壳408，以便在外壳402内保持电池404。
与图4的实施例不同，图9的实施例并不包括壁310来卡住电池而使其不在外壳内位移及提供能量导向器使能超声焊接到外壳的肩形部分。相反地，沿着外壳402的表面提供一个能量导向体以便提供超声波焊接到外壳408的底脚412。超声波焊接可沿整个能量导向体410或在选择的部分提供。
外壳402可任选地包括一个定位片414，以便在超声波焊接期间能适当地定位内壳408相对于外壳402的位置。定位机构详细地示于图10中。底脚412包括适用于空纳定位片414的一个凹槽415。最后，定位导柱416也可选择地被定位以帮助电池的制作。图11和12以在图9的线B—B剖开的横截面详细地示出了定位机构416。
现在翻到图11，图9的线B—B的剖面图表示了内壳408与外壳402的定位和在能量导向体410的超声波焊接。特别是，定位导柱416提供内壳408的基准点。另外，可包括一个坝体418，在超声波焊接期间防止内壳408的底脚412移动。即，因为能量导向体是沿着外壳402的倾斜部分放置的，在超声波焊接期间通常是水平的底脚412被迫处于倾斜位置。因此，坝体418防止底脚412离开定位导柱416的移动。虽然示出的底脚412放置在沿外壳402的一个特定位置，但是应懂得，能量导向体410可放置在沿壁310的任何位置。
翻到图12，一个可替代的实施例装入了包括能量导向体410的一个校平表面420。校平表面420防止底脚412在超声波焊接期间被迫处于倾斜位置。
总之，本发明减少了制造的复杂性和整个电池的重量。特别是，超声波焊接与粘合连接的组合可减少设备的重量和复杂性。一个壁可卡住该蓄电池。放置在该壁顶部、含有多个单元电池的蓄电池的能量导向体可提供超声波焊接区域。内壳可放置在该壁上以密封该蓄电池。内壳的肩形部分可用超声波焊接到在该壁顶部的能量导向体上。另一方案，该壁可用放置在外壳的一个能量导向体代替，其中内壳的底脚以超声波焊接到该能量定向器。因此，本发明与现有技术的设备相比减少了复杂性和成本。
