技术领域
本发明涉及电动汽车的充电领域，尤其涉及一种弹性极柱、组合件、高压组件、电连接器和电池充电盘。
背景技术
现有电动汽车的电池安装方式一般分为固定式和可换式，其中固定式的电池一般固定在汽车上，充电时直接以汽车作为充电对象。而可换式的电池一般采用活动安装的方式，电池可以随时取下，以进行更换或充电，在更换或充电完毕后，再安装到车体上。
在电池充电时，需要通过相应的电连接器与外部电源进行连接，在充电过程中，电连接器需要始终保持与电池的接触。现有的充电插头都是采用固定结构，本身没有活动调节量，一旦电池移动或晃动，则有可能导致充电接触点离开，从而导致充电中断。另外，由于电池体积较大，其充电接口与电连接器接触时，并不能总是准确对位，或是在对位后电池有可能出现移动现象，这都会影响充电效果。此外，目前的电连接器都是采用固定不动的插头与电池插接，在受到垂直方向的挤压力时，易损坏插头；电连接器中的高低压线为固定出线，在接线端是刚性连接方式，由于环境、温度、车体震动等各种影响，有可能导致接触点断开，电连接不稳定，甚至造成电连接失效或烧毁等异常现象。
此外，对于可更换的电池而言，其充电方式一般是取下后，将其放置在指定的位置，然后由人工进行充电设备的连接。该方式需要人工随时参与，增加了劳动强度，而且不适合快节奏的流水作业。

具体实施方式
下面通过实施例的方式进一步说明本发明，但并不因此将本发明限制在所述的实施例范围之中。
实施例1
如图1所示，本实施例一个实施方式的弹性极柱40一般性地包括柱体41和弹簧42。
该柱体41一端为与电池接触的电接触端411，另一端为与电源供电线连接的接线端412，在柱体41的端部外表面设置有环形凹槽413。其中，接触端411可以设置成平面形状，以提高接触面积。而环形凹槽413可以用于安装限位件，使弹性极柱40限位安装在极柱安装座50上。
该弹簧42套在柱体41的外表面并在安装后被限制在极柱安装座50内，其在柱体41的接触端411被挤压时可以产生一个与挤压方向相反的弹力，以实现柱体在极柱安装座50上的浮动安装，并可实现该极柱与电池的电接触端良好的电连接性能。
在本实施方式中，柱体41活动安装在指定部件上，如为电池充电的电连接器上，并通过卡入环形凹槽413的限位件限制其不能脱离安装位置，同时，弹簧42可以在限位件以及极柱安装座的配合下，始终对柱体41施加一个维持当前状态的弹力。当柱体41与待充电电池的充电插孔接触时，可以在受力时回缩，在减少硬性碰撞的同时，还保持良好的接触效果。
在本实施例的一个实施方式中，为方便安装充电线，可以在柱体41的接线端412设置沿柱体41的轴心线方向凹进的卡线槽414。充电线可以插入卡线槽414而与相应的柱体41连接。
在本实施例的一个实施方式中，卡入环形凹槽413的限位件可以是开口的C形卡环415，卡环415的外直径大于柱体41的直径，而内直径与环形凹槽413的直径相同，当卡环415卡入相应的环形凹槽413内后，弹簧被限位在卡环415内的柱体上，同时卡环415将极柱限位安装在极柱安装座上，使其在被电池充电端挤压的过程中无法从极柱安装座上脱出。
如图2、3所示，在本实施例的一个实施方式中，该柱体41可以包括高压极柱43和低压极柱44，分别通过高压安装孔和低压安装孔安装在极柱安装板上，且高压极柱43电接触端的直径大于低压极柱44电接触端的直径。
在本实施例的一个实施方式中，为充分利用高压极柱自身的结构，高压极柱43电接触端所在的柱体直径大于接线端所在的柱体直径，即高压极柱可以包括直径缩小段432和直径保持段432，当直径缩小段432插入极柱安装座的安装孔后露出端头，环形凹槽413则设置在露出的端头处，即在位于高压安装孔外侧的接线端的端部外表面，卡环卡合 在该凹槽内，避免高压极柱从安装座脱落，而弹簧42套在直径缩小段432上可被直径保持段431和高压安装孔夹持限定在当前位置，同时被压缩的弹簧具有将高压极柱向电接触端所在方向挤压的弹力，而卡环与该安装位置配合将该极柱卡止在该安装座内，即高压极柱43在弹簧42的弹力下由安装位置脱出时，会被位于另一端的卡入环形凹槽413的卡环415挡住。当高压极柱43受到垂直方向的压力时，其直径保持段432可在当前安装位置压缩弹簧42，使高压极柱能够在一定范围内移动。
如图3所示，在本实施例的一个实施方式中，该低压极柱44可以为直径一致的圆柱，同时在低压极柱的两端分别设置一圈环形凹槽，该环形凹槽可同时设置在低压极柱位于低压安装孔外侧的接线端的端部表面以及位于低压安装孔内侧的电接触端的端部表面，该环形凹槽内同样用于安装相应的限位件，如卡环415，弹簧套在两道环形凹槽之间的柱身上。在安装时，低压极柱可以利用两个卡环分别卡在极柱安装座的低压安装孔两端的同一侧，而弹簧位于低压安装孔内，以对安装孔的两端同时施加朝向低压极柱两端的弹力。当低压极柱受到安装孔一端的垂直压力时，可以压缩内部的弹簧而向另一端方向移动，从而使低压极柱能够始终与施压一方保持一定的压力，提高电连接效果。
本实施例的一个实施方式的电连接器可以为浮动电连接器，包括用于提供安装基座的底板10，与该底板10通过弹性件30浮动连接的浮动板20，以及通过螺钉15固定在浮动板20上的极柱安装座50，该极柱安装座50上具有用于安装弹性极柱40的安装槽，上述的弹性极柱40通过该安装槽安装在该极柱安装座50上，该底板10、浮动板20具有供弹性极柱40的接线端穿过的安装口。

其中，弹性体可以为复位弹簧，极柱81穿过该复位弹簧。复位弹簧弹性高，性能好，除去外力后易恢复原状。同时，复位弹簧对极柱81的作用力使得极柱81受力均匀，有效防止极柱81产生偏移错位现象。

当电连接器为待充电电池充电时，通过弹性极柱120与待充电电池的充电接口插接，弹性极柱120可以在与待充电电池接触后保持一定的伸缩弹性，提高接触点的接触效果。此外，浮动板100在受到外力作用时，会在弹性件110的控制下相对底板90实现一定量的平面位移，提高弹性极柱的连接效果，同时避免硬性损伤。
弹性件110可以对称地设置在底板90的安装口91四周，以使浮动板100受力均匀。在本实施方式中，弹性极柱120用于承受垂直于底板90的压力，而弹性件110可以使弹性极柱120承受平行于底板90的压力，从而实现弹性极柱在垂直和水平方向的弹性连 接，提高电连接器的适应范围。
如图11所示，在本实施例的一个实施方式中，该弹性件110的安装可以采用如下结构：
在底板90和浮动板100的边缘设置安装弹性件110的夹持座92，该夹持座92包括设置在底板90的安装口91的四周的第一固定块921，和设置在浮动板100上且与第一固定块921位置相对的第二固定块922，而弹性件110的两端分别与第一固定块921和第二固定块922连接且被两者夹持固定；整个浮动板100被对称分布的弹性件110活动夹持在底板90上。
具体的第一固定块921和第二固定块922可以是由底板90和浮动板100本身结构形成，且第一固定块921和第二固定块922之间间隔一定的距离，以容纳弹性件110。本实施方式中的弹性件110可以是弹簧或卷状弹性钢板。在采用弹簧时，其两端可以分别插在第一固定块921和第二固定块922上，其中第一固定块921和第二固定块922的尺寸小于弹簧的内径以将弹簧套在第一、第二固定块上。此外，为使第一固定块921和第二固定块922位置相对，第一固定块921或第二固定块922可以根据对方的位置进行相应弯折，以使两者处于同一平面上。为方便安装弹性件110，还可以在设置第一固定块921和第二固定块922的底板90和浮动板100上设置相应的空槽923。
在本实施例的一个实施方式中，为便于浮动板100相对底板90浮动，可以在浮动板100面对底板90的一侧设有多个凸点，以将浮动板100和底板90隔开一定距离。
进一步地，在本实施例的一个实施方式中，可以在浮动板100和底板90上分别设置第一固定孔94、102，在第一固定孔94、102内安装有将两者限定在一起的导向件95，该导向件95包括导向套和导向螺钉，导向套95安装在底板90上，导向螺钉穿过该浮动板100与导向套95通过螺纹连接，其中位于底板90上的导向套95位于第一固定孔内的直径小于第一固定孔102的孔径，而导向套95位于第一固定孔外另一端的直径大于第一固定孔102的孔径，而导向螺钉利用外螺纹或内螺纹与导向套95位于第一固定孔内的部分连接固定。
导向件95用于将浮动板100与底板90连接在一起，且连接后的浮动板100相对底板90只能产生滑动移动，即只能在第一固定孔94、102的直径范围内产生移动。此外，第一固定孔94、102的数量可以有多个且对称分布在浮动板100的四周。此外，在其它的实施方式中，导向件95也可以是铆钉。
如图11、12所示，在本实施例的一个实施方式中，该浮动板100的中部可以设置中空的浮动板安装口103，在安装口103处固定有专门用于安装弹性极柱120的极柱安装 板130。通过独立的设置的极柱安装板130可以方便安装弹性极柱120，同时方便整个电连接器的拆卸和维护。极柱安装板130与浮动板100之间可以采用固定连接。如，在浮动板100和极柱安装板130上分别设置供固定件穿过的第二固定孔104、131，在底板90与第二固定孔104、131对应的位置上设置容纳固定件的容纳孔95。这里的固定件可以是螺杆、螺帽结构。而第二固定孔104、131可以分布在极柱安装板130的四个角处。此外，为避免固定件影响浮动板100相对底板90的滑动，该固定件相对容纳孔的活动量至少与第一固定孔94、102的活动量相同。
如图12、13、14、15所示，进一步地，在本实施例的一个实施方式中，该安装板130的中部可以设置向弹性极柱120一侧凸出的凸台132，在安装板130穿过浮动板的另一侧具有向凸台132方向凹进的凹槽，该凹槽表面安装有封板133，在封板133与凸台132之间形成有用于容纳弹性极柱120的容纳空间134。
本实施方式中凸台132可以采用冲压方式直接在安装板130上形成，而封板133相对凸台132的一面可以设置与容纳空间134形状一致的卡台1331，封板130通过卡台1331插入容纳空间134后卡在安装板130上。凸台132的结构更适于弹性极柱120与待充电电池的充电插孔连接。
如图16所示，在本实施例的一个实施方式中，为方便弹性极柱120与待充电电池的插接，可以在极柱安装板130上设置限制弹性极柱120与待充电电池的充电插孔接触位置的定位柱135，该定位柱135可以设置两个，且分别安装在凸台132的两侧，该定位柱135的高度大于弹性极柱120的高度。在电连接器与待充电电池接触时，定位柱135会首先插入待充电电池上的相应固定孔，然后弹性极柱120才与待充电电池的充电插孔插接。定位柱135还可以保护插接后的弹性极柱受到的水平力影响。
如图17所示，在本实施例的一个实施方式中，该定位柱135可以通过一端固定连接在安装板130上，如具备外螺纹的螺纹端1331，而另一端为方便插接的锥形端1352，在两端之间可以设置凸出于柱身的挡板1353，挡板1353可以限定定位柱135的拧入高度。

该弹簧122套在柱体121的外表面并被限制安装在极柱安装板的安装孔内，其在柱体121的接触端1211被挤压时可以产生一个与挤压方向相反的弹力。在本实施方式中，柱体121活动安装在极柱安装板上，并通过卡入环形凹槽1213的限位件限制其不能脱离安装位置，同时，弹簧122可以在极柱安装座的配合下，始终对柱体121施加一个保持在当前状态的弹力。当柱体121与待充电电池的充电插孔接触时，可以在受力时回缩，在减少硬性碰撞的同时，还保持良好的接触效果。
在本实施例的一个实施方式中，为方便安装充电线，可以在接线端1212设置沿柱体121的轴心线方向凹进的卡线槽1214。充电线可以插入卡线槽1214而与相应的柱体121连接。

如图21所示，具体的安装结构可以如下：高压安装孔136包括第一安装段1361和第二安装段1362，且第二安装段1362的直径小于第一安装段1361的直径，高压极柱123的电接触端所在的柱体的直径大于接线端所在柱体的直径，其中接线端所在柱体为直径缩小段1232，电接触端所在的柱体为直径保持段1231，高压极柱123插入高压安装孔136后，直径保持段1231与第一安装段1361对应，而直径缩小段1232与第二安装段1362对应，且直径缩小段1232插入第二安装段1362后露出端头。环形凹槽1213设置在露出的接线端的端头处，而弹簧122套在位于高压安装孔内的直径缩小段1232上且被第二安装段1362和直径保持段1231限定在第一安装段1361内，且处于被压缩状态，高压极柱123在弹簧122的弹力下向高压安装孔136外部运动，但被卡入环形凹槽1213的卡环1215挡住。当高压极柱123受到垂直方向的压力时，其直径保持段1232在第一安 装段1361内移动以挤压弹簧122。
如图22所示，在本实施例的一个实施方式中，在极柱安装板130的凸台132和封板133上的对应位置处分别设置有直径一致的低压安装孔137，该低压极柱124的电接触端和接线端分别穿过凸台132和封板133，弹簧122安装在位于低压安装孔137内的低压极柱124的柱身上，低压极柱124上的环形凹槽1213有两个，且分别设置在低压极柱124穿过封板133的一端和位于低压安装孔137内的柱身上。
本实施方式中，低压极柱124为直径一致的圆柱。位于凸台132和封板133上的低压安装孔137直径一致，当低压极柱124插入凸台132和封板133上的低压安装孔137内后，露出封板133的一端的环形凹槽1213上卡入相应的卡环1215，以限制低压极柱124不同由凸台132方向脱离，而另一道位于安装孔137内的极柱上的环形凹槽1213卡入卡环1215后，可以对位于封板133和该卡环1215之间的弹簧122形成夹持，弹簧122利用封板133施加的压力可以使低压极柱124承受一定的垂直压力且保持露出凸台132的状态。
在本实施例的一个实施方式中，该高压极柱123可以设置两个且分别位于凸台132的两端，而低压极柱124可以设置多个且分布在两个高压极柱123之间。如，本实施方式中低压极柱124设置有上、中、下三排且按7、6、7的数量分布。
实施例4
如图23、25、26所示，本实施例公开的电动汽车的电池充电盘140一般性地包括上框组件141、下框组件142和浮动充电板143。
该上框组件141用于放置待充电的电池，包括作为支撑电池的上框架1411。该下框组件142用于弹性支撑上框架1411，包括下框架1421和设置在下框架1421上表面的弹性装置145，通过弹性装置145可以使上框架141在放置电池后，在电池的重力作用下促使上框架浮动下移指定的距离。该浮动充电板143用于为电池充电，安装在上框架1411上表面的一端，包括同时与上框架1411和下框架1421活动连接的安装座1432，以及安装在安装座1432上以与电池形成插接接触的浮动电连接器1431。安装座1432能够在上框架1411下移时随其同步移动，以使浮动电连接器1431自动与下移到位后的电池实现插接。
本实施方式利用互连的上框组件、下框组件和浮动充电板实现放置后电池的自动移动充电，通过互动的三方在移动过程中的配合，自动使浮动充电板与待充电电池实现插接，进而实现待充电电池的自动充电。本实施方式可以完全实现电动汽车的电池的自动充电，不需要人工干涉，可以提高整个充电过程的自动化处理过程，提高充电效率。
在本实施例的一个实施方式中，具体的弹性装置145可以是液压、气压或电动控制装置，其能够使上框架1411在放置电池后移动到指定的位置即可。在本发明的另一个实施方式中，该弹性装置145还可以采用压缩弹簧1451，通过选择弹簧1451的弹力与电池重量之间的关系，即可达到控制电池下移至指定位置处的效果。
进一步地，在本实施例的一个实施方式中，该弹性装置145在采用弹簧时，可以在上框架1411的下表面和下框架1421的上表面分别设置安装并限制弹簧1451的固定筒1452，压缩弹簧1451的两端分别安装在两个固定筒1452内，固定筒1452可以使上框架1411在下移时不会脱离与弹簧1451的连接。
如图24所示，在本实施例的一个实施方式中，为方便电池的放置，可以在上框组件141的上方安装限制电池移动的支撑板149，该支撑板149活动放置在上框架1411的上表面，支撑板149可以带有中空通孔。的具体的放置方式可以是：在支撑板149的下表面设置两道相互平行的L型的直角安装条1491，在上框组件141的上表面设置台阶形的卡合板1412，直角安装条1491通过一条直角边与支撑板149的下表面固定，另一直角边与支撑板149平行，两条直角安装条1491的方向相反。
卡合板1412的台阶高度与直角安装条1491的高度相同，放置后的支撑板149利用直角安装条1491卡在卡合板1412上，两条直角安装条1491分别通过一条直角边搭在对应卡合板1412的台阶上，可以防止支撑板149横向移动，该限向移动方向与浮动充电板143的移动方向对应，可以防止电池在下移时与浮动电连接器1431之间插接失误。
在本实施例的一个实施方式中，为防止电池在充电过程中出现移动，可以在上框架1411与下框架1421之间设置限制上框架1411在放置电池后相对下框架移动的限位装置147。
在本实施例的一个实施方式中，该限位装置147可以包括设置在上框架1411下表面上的锥形定位杆1471，和设置在下框架1421上表面与锥形定位杆1471位置对应处的锥形定位座1472。当电池将上框架1411下压时，上框架1411底部的锥形定位杆1471可以插入下框架1421顶部的锥形定位座1472内，从而防止上框架1411在充电过程中移动，可在上框架的下表面设置多个锥形定位杆1471，并在下框架的上表面设置有多个锥形定位座1472。
在本实施例的一个实施方式中，为防止上框架1411脱离弹性装置145的控制，同时限制上框架1411的移动方向，可以在下框组件142上设置限制上框组件141下沉时移动轨道的限位装置144，同时还可以限制上框架1411上下移动的幅度。该限位装置144包括安装在下框架1421上带有纵向滑动槽1442的限位板1441，和设置在上框架1411上 插入纵向滑动槽1442的限位杆1443。
限位板1441设置在下框架1421的四周，其上的纵向滑动槽1442与下框架1421垂直，上框架1411的限位杆1443设置在与限位板1441对位的位置且分别插入纵向滑动槽1442内，在上框架1411上未放置电池时，上框架1411被弹性装置145顶起，限位杆1443位于纵向滑动槽1442的顶端，当上框架1411上放置电池后，通过纵向滑动槽1442对限位杆1443的限定，使得上框架1411只能沿纵向滑动槽1442移动，从而限定了上框架1411的移动方向，可以在上框架的边缘设置多个限位板以提高限位效果，此外，本实施方式也可以提高限位装置147的限位效果和浮动充电板143的插接效果。
在本实施例的一个实施方式中，为使安装座1432能够与上框架1411同步动作且到达指定位置，该安装座1432可以通过滑轨装置146与上框架1411连接，通过定向装置148与下框架1421连接。其中，滑轨装置146用于限定安装座1432在上框架1411被电池压下时向沿上框架向电池方向移动，该移动可以使安装座1432上的浮动电连接器1431自动与下降的电池形成电接触。而定位装置148用于引导浮动充电板跟随电池的移动并与电池表面的电连接机构对位。
在本实施例的一个实施方式中提供一种具体的滑轨装置146，该滑轨装置146可以包括安装在安装座1432下表面上带有卡槽的滑块1462，和安装在上框架1411端头处的滑轨1461。安装座1432通过滑块1462上的卡槽卡入滑轨1461而与上框架1411滑动连接，当上框架1411下降时，滑轨1461会对滑块1462产生一个下压的拉力，从而使安装座1432在定向装置148的限制下沿滑轨1461移动，当安装座1432移动至滑轨1461的另一端时，其上的浮动电连接器1431即与上框架1411上的电池形成插接。
本实施例的一个实施方式提供一种定向装置148，该定向装置148包括设置在安装座1432下表面上带有滑轮1484的滑轮座1483，和安装在下框架1421上表面上带有斜槽1482的限向座1481，斜槽1482的倾斜方向与滑轨1461的方向相同。滑轮座1483可以是两块平行的夹板，而滑轮1484则垂直连接在两块夹板之间。当安装座1432随上框架1411同步移动且下降时，滑轮1484即沿限向座1481的斜槽1482行进，斜槽1482的倾斜角度与安装座1432滑动下移时的运动轨迹相同，且可以使安装座1432的移动不偏离与电池的插接轨道。
虽然以上描述了本发明的具体实施方式，但是本领域的技术人员应当理解，这仅是举例说明，本发明的保护范围是由所附权利要求书限定的。本领域的技术人员在不背离本发明的原理和实质的前提下，可以对这些实施方式做出多种变更或修改，但这些变更和修改均落入本发明的保护范围。
