具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本申请，而不能理解为对本申请的限制。
下面参考图1-图13描述根据本申请实施例的电池解锁装置100，包括：旋转座1、轴套2、解锁部3以及驱动部4。需要说明的是，如图3所示，在轴套2的内部设置有轴向伸缩的弹性件21和一颗归中滚珠22；如图10所示，在旋转座1内的轴线位置处设置有锥形归中槽11，且使轴套2的轴线与锥形归中槽11的槽心保持在同一轴线上。以及，使锥形归中槽11的开口宽度大于归中滚珠22的直径，可确保归中滚珠22的至少部分能够锥形归中槽11内进行活动。
具体地，在实际安装时，可将旋转座1的一端安装于驱动部4，然后将轴套2的一端与旋转座1的另一端配合安装，且将解锁部3与轴套2的另一端活动安装。其中，轴套2内的归中滚珠22安装于旋转座1中的锥形归中槽11内，使得归中滚珠22可在锥形归中槽11内活动。以及，将轴套2内的弹性件21的底部抵压于归中滚珠22的上方，且将弹性件21的顶部抵压于解锁部3的底部，使得弹性件21可与归中滚珠22在轴套2的轴向上保持正对，且弹性件21还可与解锁部3在轴套2的轴向上保持正对。其中，弹性件21在安装时处于被压缩的状态，使得弹性件21可对顶部的解锁部3以及底部的归中滚珠22提供推力或压力，即处于一种预紧状态。
可以理解的是，电池解锁装置100的工作过程为：当启动电池解锁装置100时，驱动部4向与之连接的旋转座1提供动力，使得旋转座1做周向转动，从而旋转座1可带动轴套2进行周向转动，轴套2可带动解锁部3进行周向转动。由此，解锁部3将拧紧动力电池的螺栓或放松动力电池的螺栓。其中，在旋转座1、轴套2、解锁部3做周向转动的同时，通过将弹性件21预紧于解锁部3和旋转座1之间，使得归中滚珠22和解锁部3均对轴套2施加压力。由此，轴套2在工作时受到压力从而在XY平面上浮动且向轴线靠拢，保证了解锁部3、轴套2及旋转座1可保持在同一轴线上，实现轴套2归中，进而可解决锁体和解锁机构不同轴的问题。
以及，如图2所示，电池解锁装置100在工作时，因弹性件21在轴套2内有预紧力，使得弹性件21产生的弹力可对解锁部3施加推力，可将解锁部3相对于轴套2进行轴向的伸缩运动。由此，通过解锁部3可在轴向上进行伸缩运动，可方便电池解锁装 置100伸至电动汽车内进行拧紧或松开动力电池，且避免电池解锁装置100发生磕碰问题，起到保护作用。
根据本申请实施例的电池解锁装置100，通过归中滚珠22在锥形归中槽11内活动可使得轴套2在XY平面进行浮动，从而保证轴套2归中，解决锁体与电池解锁装置100不同轴的问题。
在一些实施例中，轴套2内形成有安装腔23，安装腔23在轴套2的第一端敞开且在轴套2的第二端设有归中孔24。需要说明的是，安装腔23可构造为端面为正方形且内部为轴向延伸的矩体空腔结构，且轴套2在第二端处设有与归中滚珠22的大小适配的归中孔24。其中，轴套2的第一端用于与解锁部3进行滑动配合，且使第二端的归中滚珠22在旋转座1的锥形归中槽11内进行滚动。具体地，将弹性件21轴向安装于安装腔23内，然后将解锁部3的底部插入安装腔23内且抵压于弹性件21，使得解锁部3可在轴套2的第一端处与弹性件21滑动配合。
其中，如图8所示，归中滚珠22的直径近似归中孔24的直径，且归中孔24的轴向长度小于归中滚珠22的直径，从而当归中滚珠22安装于归中孔24上时，归中滚珠22的底部可与锥形归中槽11的侧壁相抵并发生滚动。
可以理解的是，在连接好的情况下，当解锁部3的顶部抵压动力电池时，弹簧受到解锁部3的压力和归中滚珠22的压力，使得轴套2在进行周向转动的过程中不断地在XY平面上浮动，且归中滚珠22在锥形归中槽11内滚动时，根据受力分析可知，归中滚珠22在运动中可向锥形归中槽11的槽心移动。由此，轴套2的轴线在浮动的过程中向解锁部3的轴线和旋转座1的轴线移动，从而保证轴套2的轴线可与解锁部3和旋转座1的轴线保持在同一轴线上，实现轴套2以及解锁部3的归中效果。
在一些实施例中，安装腔23内设有可活动的压片25，且压片25位于弹性件21与归中滚珠22之间。需要说明的是，如图4所示，压片25构造为圆形片，且压片25的直径与安装腔23的直径相同，从而保证弹性件21能够抵压于压片25。也就是说，在实际安装中，将归中滚珠22安装于归中孔24内，将压片25安装于安装腔23的底部且与归中滚珠22的顶部相抵，再将弹性件21安装于安装腔23内并相抵于压片25。由此，弹性件21与归中滚珠22之间施加的作用力与反作用力均可通过压片25传递于彼此，且通过压片25可将力集中于轴套2的轴线上，从而有利于轴套2的归中。
在一些实施例中，弹性件21构造为弹簧，且弹性件21的轴线和轴套2的轴线重合，且归中滚珠22的圆心位于轴套2的轴线所在的直线上，且锥形归中槽11的轴线与旋转座1的轴线重合。也就是说，将弹性件21构造为与安装腔23直径大小相同的弹簧，可使得弹簧质心与轴套2轴线处于同一轴线上，即弹簧轴线可与轴套2轴线重合。以及， 归中孔24和锥形归中槽11均设置于轴套2的轴线位置处。以此，可使得设置于归中孔24中的归中滚珠22的轴线与轴套2的轴线一致，且旋转座1的轴线与轴套2的轴线一致。从而可保证旋转座1、归中滚珠22、轴套2同轴线的进行转动。
在一些实施例中，电池解锁装置100还包括：盖板5，旋转座1设有容纳腔12。需要说明的是，如图9所示，旋转座1靠近轴套2的一侧构造出容纳腔12，且容纳腔12构造为与轴套2外壳相适配的形状。以及，在盖板5上设置有多个第一安装孔51，且在旋转座1外周壁的端面上设置有第二安装孔13。其中，第一安装孔51的直径大小和第二安装孔13的直径大小相同。
具体地，在实际安装中，将轴套2安装于容纳腔12内，且将盖板5套设于轴套2上，并与旋转座1的端面相抵，然后再使用螺栓依次穿设第一安装孔51、第二安装孔13以将盖板5与旋转座1可拆卸地连接。由此，可通过盖板5与旋转座1的稳固连接将轴套2稳定的安装于旋转座1的容纳腔12内，且通过螺栓连接的方式有利于后期维护轴套2或更换轴套2，从而降低维修成本。
其中，在轴套2的外周壁上还设置有支撑盘26，支撑盘26可伸至容纳腔12内并与旋转座1配合安装，且支撑盘26可浮动支撑于旋转座1与盖板5之间，从而可使得轴套2能在XY平面内浮动以提高轴套2的归中效果，使得轴套2与旋转座1共线，有利于提高加解锁的成功率。
在一些实施例中，容纳腔12设有浮动调节环6。需要说明的是，如图4所示，浮动调节环6的直径与支撑盘26相同，且浮动调节环6套设于轴套2内，支撑盘26的下端以与轴套2均安装于容纳腔12内。其中，在浮动调节环6内设置有多个第一配合孔61，并在每个第一配合孔61上设有一个第一浮动滚珠62，且在容纳腔12内同样设置有多个第二配合孔121。
具体地，在本实施例中，浮动调节环6内共设有8个第一浮动滚珠62，且8个第一浮动滚珠62的直径大于浮动调节环6的轴向厚度，使得第一浮动滚珠62能够相抵于容纳腔12内的第二配合孔121。即第一浮动滚珠62可分别支撑于支撑盘26的第一配合孔61和容纳腔12的内底壁的第二配合孔121。由此，在安装好的情况下，通过多个第一浮动滚珠62的滚动可使轴向上的浮动调节环6以及轴套2能够在XY平面上进行浮动。
当然，第一浮动滚珠62的数量并不局限于8个，只要其数量大于等于3个就可以实现该功能。第一浮动滚珠62的数量也可以为4个、5个、6个、7个或更多。
在一些实施例中，浮动调节环6的一侧设有第一限位传动部63，第一限位传动部63与旋转座1周向限位配合。也就是说，如图11所示，背离解锁部3的一侧设置有两个第一限位传动部63，第一限位传动部63构造为凸出浮动调节环6背离解锁部3一侧 的方块状结构，且两个第一限位传动部63在浮动调节环6上相对于轴线对称设置。其中，在容纳腔12的内底壁上设置有两个对称且大小相同的第一卡接槽122。具体地，第一卡接槽122构造为容纳腔12的内底壁上的凹槽结构，且第一卡接槽122的大小与第一限位传动部63的大小适配，可通过第一限位传动部63与第一卡接槽122的配合以将浮动调节环6稳定的安装于旋转座1上，从而当旋转座1进行周向转动时可带动浮动调节环6进行周向转动。
以及，浮动调节环6的另一侧设有第二限位传动部64，第二限位传动部64与支撑盘26周向限位配合。也就是说，如图11所示，在浮动调节环6靠近解锁部3的一侧设置有第二限位传动部64，第二限位传动部64构造为凸出浮动调节环6靠近解锁部3一侧的方块状结构，且两个第二限位传动部64在浮动调节环6上相对于轴线对称设置。其中，在轴套2的支撑盘26上设置有两个轴向对称且大小相同的第二卡接槽261，具体地，第二卡接槽261构造为支撑盘26上的凹槽结构，且第二卡接槽261的大小与第二限位传动部64的大小适配，可通过第二限位传动部64与第二卡接槽261的配合以将轴套2稳定的安装于浮动调节环6上，从而当浮动调节环6进行轴向转动时可带动轴套2进行周向转动。
在一些实施例中，盖板5与支撑盘26之间还设有套设于轴套2的滚环7。需要说明的是，如图12所示，滚环7构造为圆环状结构，滚环7的直径与支撑盘26的直径相同，且在滚环7的端面上设置有12个大小相同的第三配合孔71。以及，每个第三配合孔71内设有1个第二浮动滚珠72，第二浮动滚珠72可安装于第三配合孔71上。其中，第二浮动滚珠72的直径大于滚环7的轴向厚度。由此，将滚环7套设于轴套2上，使得12第二浮动滚珠72可相抵于支撑盘26的顶部，从而可通过多个第二浮动滚珠72的滚动进而保证轴套2在XY平面上浮动的协调性，以便于轴套2传递扭矩。
当然，第二浮动滚珠72的数量并不局限于12个，只要其数量大于等于3个就可以实现该功能。第二浮动滚珠72的数量也可以为4个、5个、6个、7个或更多。
以及，如图7及图12所示，在滚环7上还设置有轴向对称且大小相同的两个第三卡接槽73，在支撑盘26靠近解锁部3的一侧的端面上凸出设置有两个轴向对称且大小相同的第三限位传动部262。第三限位传动部262与第三卡接槽73可卡接适配，从而可将滚环7卡接在支撑盘26上，从而保证滚环7与轴套2能够同时进行转动，避免二者发生相对旋转以影响轴套2的浮动效果。
在一些实施例中，解锁部3包括方轴31和套筒32，方轴31与轴套2可活动地相连，套筒32可拆卸地连接于方轴31背离轴套2的一端。也就是说，解锁部3由方轴31和套筒32连接组成。其中，方轴31可活动的连接于轴套2，使得方轴31能够沿轴向做伸 缩运动。
具体地，套筒32连接于方轴31背离轴套2的一端，且使得套筒32可与方轴31进行可拆卸地连接，从而满足不同尺寸的套筒32与方轴31的连接。也就是说，不同尺寸的套筒32的底部均可与方轴31卡接，即不同尺寸的套筒32，其底部大小均相同，即不同尺寸的套筒32均可与方轴31的一端连接，以满足套筒32底部与方轴31背离轴套2的一端卡接适配，从而可满足解锁装置可作用于不同尺寸大小的螺栓，提高实用性。其中，弹性件21弹性抵压于方轴31，可推动方轴31在轴向移动，提高电池解锁装置100的轴向长度，从而利于电池解锁装置100与动力电池的连接。
在一些实施例中，方轴31设有长条孔311，轴套2设有沿径向贯通的第一限位孔27，轴套2内设有限位穿设于长条孔311和第一限位孔27的限位销29。需要说明的是，如图6所示，长条孔311设置于解锁部3插入安装腔23内的方轴31之中。其中，长条孔311的孔径大小略大于轴套2内的限位销29的直径或将二者配合设计，保证限位销29可穿设长条孔311即可。也就是说，轴套2设有两个第一限位孔27，且两个第一限位孔27轴向对称的设置在轴套2靠近解锁部3一端的外周壁上，且两个第一限位孔27的孔径大小均相同，并与限位销29的直径大小保持一致。在实际安装时，可先将解锁部3的一部分插入安装腔23内，使解锁部3中的长条孔311对准两个第一限位孔27。
可以理解的是，当弹性件21推动方轴31在安装腔23内运动时，方轴31的运动距离将通过长条孔311与限位销29的配合决定，即方轴31的最大运动距离不超过长条孔311的长度，当限位销29与长条孔311的端部相抵时，方轴31停止轴向运动。由此，当方轴31在轴向上运动至长条孔311与限位销29相抵时，方轴31停止轴向运动。如此，可保证方轴31能够稳定的在轴套2内活动且实现了解锁部3与轴套2的连接。
在一些实施例中，方轴31背离轴套2的一端设有连接段312，套筒32设有沿轴向敞开的连接腔321，连接段312伸至连接腔321内且与穿设于套筒32的连接销324限位配合。需要说明的是，如图5所示，连接段312上设置有第一销孔3121，在套筒32的底部外周壁上设置有轴向对称的两个第二限位孔322。也就是说，当连接段312伸至连接腔321时，使连接段312中的第一销孔3121对准两个第二限位孔322，再通过连接销324依次穿过第二限位孔322、第一销孔3121和另一个第二限位孔322，从而将连接段312与套筒32固定连接。进而提高套筒32与方轴31的连接稳定性和解锁过程的操作可靠性。
在一些实施例中，驱动部4与旋转座1通过连接件可拆卸地相连。需要说明的是，如图13所示，在驱动部4与旋转座1相连的一面设置有第三安装孔41，且在驱动部4中心处还构造有第二安装腔42。
具体地，在实际安装中，将旋转座1安装于第二安装腔42内，使得旋转座1的底部可相抵于驱动部4端面的第三安装孔41，然后再通过螺栓依次穿设第三安装孔41以将旋转座1与驱动部4可拆卸地连接。由此，可通过旋转座1与驱动部4的稳固连接可将驱动部4产生的驱动力稳定传递至旋转座1，且利用螺栓连接有利于后期维护或更换旋转座1，可降低维修成本。
本申请还提出一种换电平台。
根据本申请实施例的换电平台，设置有上述中任一项的电池解锁装置100。通过在轴套2内设置与弹性件21相抵的归中滚珠22，并将归中滚珠22与旋转座1中的锥形归中槽11配合抵压，从而实现轴套2与旋转座1的共轴线。以及，轴套2与解锁部3通过卡接和连接销324的方式稳定连接，从而实现解锁部3与轴套2的共轴线。由此，当电池解锁装置100与动力电池连接时，可解决电池包加工公差引起的锁体部与电池解锁装置100的不同轴的问题。其中，电池解锁装置100还可通过设置弹性件21使得解锁部3可沿轴向进行伸缩运动，从而可使得电池解锁装置100易于工作且保护装置不被破坏。
