该铰链装置40包括铰链座410、第一铰链臂420、第二铰链臂430、第一销轴440、第二销轴450、第三销轴460及手柄470。所述铰链座410与所述固定框架20连接，所述第一铰链臂420通过所述第一销轴440与所述铰链座410铰接，所述第二铰链臂430通过所述第二销轴450与所述第一铰链臂420铰接，所述第二铰链臂430通过所述第三销轴460与所述压板30铰接。所述手柄470与所述第一铰链臂420固定连接，该手柄470用于带动所述第一铰链臂420进行转动，从而使所述第一铰链臂420带动所述第二铰链臂430进行转动，进而带动所述压板30靠近或远离所述底板10。该铰链装置40具有一死点位置，该死点位置是所述第一铰链臂420和所述第二铰链臂430转动到使所述第一销轴440、所述第二销轴450及所述第三销轴460处于同一直线时的位置。当所述第一铰链臂420和所述第二铰链臂430在所述手柄470的带动下到达所述死点位置时，放置在所述压板30与所述底板10之间的所述电池单体50被压紧。当该第一铰链臂420和该第二铰链臂430到达所述死点位置时，该加压装置处于锁定状态，当该第一铰链臂420和该第二铰链臂430未到达所述死点位置时，该加压装置处于打开状态。
所述底板10和所述压板30为刚性的板状结构。当该加压装置处于锁定状态时，所述底板10和所述压板30平行间隔设置，所述压板30沿其厚度方向且面向所述底板10的方向X对该电池单体50施加压力，从而使该电池单体50被压紧。所述压板30上可进一步设置有凹槽320，所述压板30可通过该凹槽320卡在所述固定框架20上，使该压板310只能沿所述方向X移动，不能在其他方向上移动。优选地，所述底板10和所述压板30的电阻等于高于500MΩ，以防止漏电、短路等事件发生。优选地，所述底板10和所述压板30均经过阳极氧化绝缘处理，通过该处理不仅能使所述底板10和所述压板30绝缘，还可使所述底板10和所述压板30具有良好的传热性能和抗腐蚀性能。优选地，所述底板10和所述压板30在所述电池单体50放入与取出的一侧的棱边具有倒角，可防止所述电池单体50在放入与取出时被刮伤。所述电池单体50可为方形或片状的软包装电池。
所述固定框架20用于使该铰链装置40及该压板30与该底板10沿所述方向X间隔设置。所述固定框架20与所述底板10的连接关系不限，只要该固定框架20与该底板10的相对位置固定，且能使通过所述铰链装置40与该固定框架20连接的压板30能与该底板10间隔设置并形成所述容置空间即可。优选地，所述固定框架20固定在所述底板10上。该固定框架20可包括固定架220及多个支撑体210。该多个支撑体210用于支撑、固定并间隔所述固定架220与所述底板10。该支撑体210的两端分别与所述底板10与所述固定架220固定连接。该多个支撑体210可设置在所述底板10的边缘处。该支撑体210可通过螺栓与所述底板10固定连接。所述压板30可通过所述凹槽320卡在该多个支撑体210上，以使该压板30只能沿该支撑体在所述方向X上移动，而不能在其他方向上移动，保证该压板30平衡地靠近或远离所述底板10。所述铰链装置40与该固定架220连接。该固定架220可为一固定板，也可为多个固定边框。该固定架220在所述方向X上具有第一通孔222，用于使该固定架220与所述铰链装置40连接。进一步地，该支撑体210与该固定架220为中空结构，以使该固定框架20具有更轻的质量，从而减轻了整个加压装置的重量，使该加压装置的使用更方便。
在本发明实施例中，所述支撑体210为立柱，所述立柱的数量为4个，所述固定架220为所述固定边框，所述固定边框的数量为2个，每个所述固定边框分别与两个所述立柱形成一U形框架，所述立柱在所述底板10的边缘处通过螺栓固定于所述底板10上，该两个U形框架平行间隔设置。优选地，所述U形框架一体成型。
所述铰链装置40通过所述铰链座410与所述固定架220连接。具体地，所述铰链座410的一端与所述固定架220连接，另一端与所述第一铰链臂420铰接。所述铰链座410可与所述固定架220固定连接，也可与所述固定架220可活动地连接。
在一实施例中，该铰链座410与该固定架220固定连接。具体地，所述铰链座410位于所述固定架220面向所述压板30的一侧，且该铰链座410面向所述固定架220的一侧设置有螺孔，一螺栓穿过所述第一通孔222并螺接在所述铰链座410的螺孔上，从而使该铰链座410与该固定架220固定连接。
在另一实施例中，该铰链座410与该固定架220可活动地连接。具体地，所述铰链座410包括沿所述方向X同轴设置且依次连接的第一连接段412及第二连接段414。所述第一连接段410贯穿所述第一通孔222并可在所述第一通孔222中沿所述方向X滑动，所述第一连接段412在所述第一通孔222远离所述压板30的一侧与一垫片490固定连接，当该加压装置处于打开状态时，该铰链座410在该第一通孔222远离该压板30的一侧通过该垫片490卡在该固定架220上，从而使该铰链座410不会脱离该固定架220。所述第二连接段414位于所述第一通孔222靠近所述压板30的一侧，当该加压装置处于锁定状态时，该铰链座410在该第一通孔222面向该压板30的一侧通过该第二连接段414卡在该固定架220上，使该铰链装置40固定，并使该固定架220通过该第二连接段414对该铰链装置40及该压板30施加一沿所述方向X的压力，从而使该电池单体50压紧。该第二连接段414在与所述第一连接段412连接的地方形成一背向所述压板30的台阶面416，当该加压装置处于锁定状态时，该台阶面416与所述固定架220接触，从而使该铰链座410卡在该固定架220上。
所述第一连接段410可通过螺栓480与所述垫片490固定连接。具体地，所述垫片490上具有孔洞，所述第一连接段412背向所述压板30的一侧设置有螺孔，所述螺栓480穿过该垫片490的孔洞与该第一连接段412的螺孔螺接，从而使该第一连接段412与该垫片490固定连接。
所述固定架220在所述方向X上还可具有与所述第一通孔222同轴设置的第二通孔224，该第二通孔224位于该第一通孔222面向所述压板30的一侧，该第二连接段414可穿入该第二通孔224并在该第二通孔224中沿所述方向X滑动。该第二通孔224可进一步限制该第二连接段414在所述方向X以外的方向上运动，从而防止所述第一铰链臂420和所述第二铰链臂430越过死点位置而产生失稳的情况。该第二通孔224的半径大于所述第一通孔222的半径。当该固定架220为实心结构时，该第一通孔222与该第二通孔224共同形成一阶梯孔。当该固定架220为空心结构时，该第一通孔222与该第二通孔224分别位于该空心的固定架220背离所述压板30的一侧和面向所述压板30的一侧。
所述铰链座410可通过该第二连接段414与所述第一铰链臂420铰接。进一步地，所述铰链座410还可包括第三连接段418，该第三连接段418位于所述第二连接段414远离所述第一连接段412的一侧并与所述第二连接段414同轴设置，该铰链座410可通过该第三连接段418与所述第一铰链臂420铰接。优选地，所述所述第一连接段412、所述第二连接段414及所述第三连接段418一体成型，从而使该铰链装置40与该固定框架20的连接更牢固。优选地，该第一连接段412与该第一通孔222、该第二连接段414与该第二通孔224均采用小间隙孔轴的方式进行配合，以使该第一连接段412与该第二连接段414能分别在该第一通孔222和第二通孔224中延所述方向X自由滑动，而又不会使该铰链座410产生太大的径向晃动而使所述第一铰链臂420和所述第二铰链臂430越过死点位置而产生失稳。
所述铰链座410还可进一步包括弹性元件60，该弹性元件60沿所述方向X设置于所述第二连接段414与所述固定架220之间。在所述加压装置处于锁定状态时，该弹性元件60处于压缩状态，并向所述铰链座410提供一压向所述压板30的压力，保证所述压板30对电池单体50的有效压紧；然而，该弹性元件60并非处于弹性压缩极限，即还可进一步弹性压缩，从而使所述压板30与所述底板10之间的距离可调节，来适应不同电池单体50因制造误差而产生的厚度变化及同一电池单体50在化成时极板膨胀引起的厚度变化，同时保证该压板30对电池单体50的有效压紧。该弹性元件60可设置于所述台阶面416与所述固定架220之间。该弹性元件可为弹簧、弹性柱或弹片。优选地，该弹性元件为蝶形弹簧，该蝶形弹簧可套在所述第一连接段412上，该蝶形弹簧在其形变方向上具有相对的第一端和第二端，该蝶形弹簧的第一端与所述台阶面416接触，该蝶形弹簧的第二端与所述固定架220接触。
所述第一铰链臂420、所述第二铰链臂430、所述第一销轴440、所述第二销轴450、所述第三销轴460及所述手柄470组成一死点机构，其中该第一铰链臂420通过所述铰链座410与所述固定框架20连接，该第二铰链臂430与所述压板30连接，当该第一铰链臂420和第二铰链臂430在该手柄470的带动下达到所述死点位置时，放置在该压板30及该底板10之间的电池单体50被压紧。所述第一铰链臂420和所述第二铰链臂430在其长度方向上分别具有相对的第一端和第二端，所述第一铰链臂420的第一端通过所述第一销轴440与所述铰链座420铰接，所述第一铰链臂420的第二端通过所述第二销轴450与所述第二铰链臂430的第一端铰接，所述第二铰链臂430的第二端通过所述第三销轴460与所述压板30铰接。所述第一销轴440、所述第二销轴450及所述第三销轴460互相平行间隔设置，以保证所述第一铰链臂420和所述第二铰链臂的转动轴向平行。
所述加压装置可进一步包括限位挡板70。该限位挡板70设置于所述第二铰链臂430的转动轨迹上，当所述第二铰链臂430到达所述死点位置时，该限位挡板70用于阻止所述第二铰链臂430继续转动，从而可防止所述第一铰链臂420和所述第二铰链臂430越过所述死点位置而产生失稳的情况，保证所述锂离子电池加压装置的可靠性。
所述加压装置还可进一步包括角铁80。所述压板30可以通过该角铁80与所述第二铰链臂430铰接。所述角铁80包括两个一体成型且相互垂直的侧板，其中一个侧板与所述压板30叠加设置且与所述压板30固定连接，另一个侧板垂直于所述压板30设置且通过所述第三销轴460与所述第二铰链臂430铰接。与所述压板30叠加设置的侧板可与所述压板30通过所述螺栓480固定连接。所述限位挡板70可设置在该角铁80与所述压板30垂直设置的侧板上。优选地，所述限位挡板70可焊接在所述角铁80与所述压板30垂直设置的侧板上。
该铰链装置40的数量和设置位置不限，只要能使该压板30与该底板10间隔设置，并能带动该压板30靠近或远离该底板10即可。当该铰链装置40的数量为1个时，该铰链装置40可设置在所述压板30的重心位置。当该铰链装置40的数量为多个时，该多个铰链装置40可形成一个对称结构，以带动所述压板30对称地靠近或远离所述底板10。在本实施例中，该铰链装置40的数量为四个，该四个铰链装置40与该压板30进行铰接的四个铰接点形成一个平行四边形，该四个铰链装置可带动该压板30对称地靠近或远离所述底板10，并且该四个铰链装置可均匀地对所述压板30施力，从而对该电池单体50均匀地受力压紧。该四个铰链装置40分为两组，每组包括两个同轴设置的铰链装置40，组与组之间的铰链装置40不同轴设置。所述同轴设置是指两个所述铰链装置40的转动轴相同。该四个铰链装置40共用两个手柄470，每一手柄470同时与两个同轴设置的铰链装置40的第一铰链臂420固定连接，用于同时带动该两个铰链装置40进行转动。具体地，该手柄470包括一连接梁472和一控制柄474，该连接梁472长度方向的两端分别与一个铰链装置40的第一铰链臂420固定连接，该控制柄474与该连接梁472的中部固定连接。该控制柄474可与该连接梁472一体成型，该连接梁472可通过螺栓与第一铰链臂420固定连接。在实际应用时，人的两手可同时操作该两个控制柄474，使该两个连接梁472同时转动，从而同时带动该四个铰链装置40转动，使该压板30对称地远离或靠近所述底板10。
