第一方面，本申请提供一种用电设备的电池更换方法，其包括：将换电装置移动到用电设备的下侧；换电装置的浮动平台向上移动以靠近用电设备，安装于浮动平台的定位件相对于浮动平台向上移动；当定位件插入用电设备的定位孔并到达第一预定位置时，浮动平台继续向上移动，定位件相对于浮动平台向下移动，并使定位件的至少部分保持在定位孔内；在浮动平台移动到第二预定位置时，浮动平台用于支撑从用电设备拆下的电池或者将电池安装到用电设备。
上述技术方案中，在定位件向上移动以伸入定位孔的过程中，浮动平台的向上移动和定位件相对于浮动平台的向上移动同步进行，这样既可 以增大定位件伸入定位孔的速率，节省定位件插入定位孔的时间，还能够利用这段时间来举升浮动平台，从而提升效率。当定位件插入用电设备的定位孔并到达第一预定位置时，定位件相对于浮动平台向下移动，这样可以降低定位件在浮动平台的带动下的移动幅度，减小定位件在定位孔内的行程，降低对定位孔尺寸的要求，提高换电装置的适用性。
在一些实施方式中，电池更换方法还包括：在浮动平台移动到第二预定位置之后，定位件相对于浮动平台继续向下移动并脱离定位孔。

上述技术方案中，浮动平台可以带动解锁机构靠近用电设备，以便于解锁机构解除电池与用电设备的用电主体之间的锁定；浮动平台可以在解锁电池后支撑电池，从而避免电池摔落，提高安全性。
在一些实施方式中，电池更换方法还包括：在解除电池与用电主体之间的锁定之后，浮动平台向下移动，以使电池与用电主体分离。

上述技术方案的换电装置可采用上述的电池更换方法，以提升电池更换的效率，提高适用性。
在一些实施方式中，换电装置还包括驱动件，安装于浮动平台并与定位件相连，以驱动定位件相对于浮动平台移动。

随着新能源技术发展，使用电池的设备增多，用电设备电能告罄时，常通过连接充电装置的方式补充电能，例如电动车辆可以连接充电桩充电。 相比连接充电桩等充电装置来补充电能的方式，充电会耗费较长的时间，影响用户体验。
发明人注意到，相较于充电，更换电池能够更快实现补充电能。为此，发明人设计了一种换电装置，其能够支撑电池并完成电池的更换。示例性地，换电装置包括浮动平台，浮动平台能够在拆装电池的过程中支撑电池。浮动平台上通常设置有定位件，定位件通过与用电设备的定位孔配合实现浮动平台以及浮动平台上的其它结构与用电设备的定位。
发明人注意到，定位件通常固定于浮动平台。定位件限定出换电装置在高度方向上的最高位置，导致换电装置的高度尺寸较大，在高度方向上占用较大的空间。由于定位件固定于定位平台，需要用电设备适应定位件的高度，一般用电设备的体积较大，通过用电设备适应定位件的高度操作不方便，电池更换效率低。
发明人尝试将定位件设置为相对于浮动平台可移动，以调节定位件相对于浮动平台的高度。在换电装置运输电池或者换电装置不工作的情况下，定位件相对于浮动平台向下移动以降低定位件的高度，从而减小换电装置的高度尺寸。在需要更换用电设备的电池时，驱动定位件相对于浮动平台向上移动，以调高定位件的高度，以使定位件与用电设备定位配合。通过定位件的移动实现与用电设备的定位配合，操作简单，效率高，且将定位件调整至不同的高度位置，定位件能够适应不同高度的用电设备。
在换电装置移动到用电设备的下侧后，定位件向上移动以与用电设备定位孔配合，然后，浮动平台向上移动以更换电池。发明人发现，在浮动平台上升的过程中，定位件会随着浮动平台继续上升，用电设备的定位孔需要具有较大的尺寸，以满足定位件的行程要求，避免用电设备干涉定位件。但是，增大定位孔的尺寸会增加对用电设备的限制，影响换电装置的适用性。另外，定位件伸入导向孔的过程与浮动平台向上移动的过程分开进行，造成耗时偏长，电池更换效率较低。
鉴于此，本申请实施例提供了一种用电设备的电池更换方法，其包括：将换电装置移动到用电设备的下侧；换电装置的浮动平台向上移动以靠近用电设备，安装于浮动平台的定位件相对于浮动平台向上移动；当定 位件插入用电设备的定位孔并到达第一预定位置时，浮动平台继续向上移动，定位件相对于浮动平台向下移动，并使定位件的至少部分保持在定位孔内；在浮动平台移动到第二预定位置时，浮动平台用于支撑从用电设备拆下的电池或者将电池安装到用电设备。
在本实施例中，在定位件向上移动以伸入定位孔的过程中，浮动平台的向上移动和定位件相对于浮动平台的向上移动同步进行，这样可以增大定位件伸入定位孔的速率，节省时间。当定位件插入用电设备的定位孔并到达第一预定位置时，定位件相对于浮动平台向下移动，这样可以降低定位件在浮动平台的带动下的移动幅度，减小定位件在定位孔内行程，降低对定位孔尺寸的要求，提高换电装置的适用性。
本申请实施例公开用电设备的电池更换方法以及用于实现该电池更换方法的换电装置、换电系统可用于车辆。车辆可以是燃油汽车、燃气汽车或新能源汽车，新能源汽车可以是纯电动汽车、混合动力汽车或增程式汽车等。
图1为本申请一些实施例提供的用电设备的电池更换方法的流程示意图；图2至图6为本申请一些实施例提供的换电装置在更换电池的过程中的示意图。
如图1至图6所示，本申请实施例的用电设备的电池更换方法包括：
S100、将换电装置1移动到用电设备2的下侧；
S200、换电装置1的浮动平台11向上移动以靠近用电设备2，安装于浮动平台11的定位件12相对于浮动平台11向上移动；
S300、当定位件12插入用电设备2的定位孔21并到达第一预定位置时，浮动平台11继续向上移动，定位件12相对于浮动平台11向下移动，并使定位件12的至少部分保持在定位孔21内；
S400、在浮动平台11移动到第二预定位置时，浮动平台11用于支撑从用电设备2拆下的电池22或者将电池22安装到用电设备2。
本实施例的电池更换方法可用于将用电设备2上的电能告罄的待充电的电池22拆下，也可以用于将满充电池22安装到用电设备2上。在一些示例中，在步骤S100中，换电装置1的浮动平台11未设置电池22，对 应地，在步骤S400中，浮动平台11用于支撑从用电设备2拆下的电池22。在另一些示例中，步骤S100中，浮动平台11上支撑有电池22，浮动平台11用于将电池22举升并安装到用电设备2。
在步骤S200中，定位件12的朝向定位孔21的端部相对于浮动平台11向上移动。
示例性地，在步骤S200中，浮动平台11向上移动的速率为V1，定位件12相对于浮动平台11向上移动的速率为V2，此时，浮动平台11向上移动的速率为V1+V2。浮动平台11的向上移动和定位件12相对于浮动平台11的向上移动同步进行，这样既可以增大定位件12伸入定位孔21的速率，节省定位件12插入定位孔21的时间，还能够利用这段时间来举升浮动平台11，从而提升效率。
在步骤S300中，当定位件12插入用电设备2的定位孔21并到达第一预定位置后，定位件12与定位孔21插接配合；在浮动平台11继续向上移动的过程中，定位件12与定位孔21的配合能够引导浮动平台11的移动，保证浮动平台11与用电设备2之间的对位精度，从而提高电池22拆装的效率。
示例性地，在步骤S300中，浮动平台11向上移动的速率为V1，定位件12相对于浮动平台11向下移动的速率为V3，这样，定位件12在定位孔21中的移动速率V4＝V1-V3。V4可以大于0、等于0或小于0。V4大于0时，定位件12在定位孔21中向上运动；V4小于0时，定位件12在定位孔21中向下运动；V4等于0时，定位件12在定位孔21中保持静止。换言之，在步骤S300中，当定位件12达到第一预定位置后，定位件12可以在定位孔21内上升、下降或静止，只要在浮动平台11移动到第二预定位置之前，保持定位件12与定位孔21的配合即可。本实施例可以降低定位件12在定位孔21中的移动速率，减小定位件12在定位孔21中的行程。
在浮动平台11移动到第二预定位置时，浮动平台11停止移动，换电装置1对电池22进行拆装操作。示例性地，当换电装置1将用电设备2的待充电的电池22拆下后，浮动平台11可以支撑电池22，降低电池22摔落的风险。
在步骤S400中，当浮动平台11移动到第二预定位置之后，定位件12可以继续相对于浮动平台11向下移动，也可以相对于浮动平台11停止移动。
在本实施例中，在定位件12向上移动以伸入定位孔21的过程中，浮动平台11的向上移动和定位件12相对于浮动平台11的向上移动同步进行，这样既可以增大定位件12伸入定位孔21的速率，节省定位件12插入定位孔21的时间，还能够利用这段时间来举升浮动平台11，从而提升效率。当定位件12插入用电设备2的定位孔21并到达第一预定位置时，定位件12相对于浮动平台11向下移动，这样可以降低定位件12在浮动平台11的带动下的移动幅度，减小定位件12在定位孔21内的行程，降低对定位孔21尺寸的要求，提高换电装置1的适用性。
在一些实施例中，电池更换方法还包括：S500、在浮动平台11移动到第二预定位置之后，定位件12相对于浮动平台11继续向下移动并脱离定位孔21。
在本实施例中，定位件12可以利用浮动平台11拆装电池22的时间向下移动，以降低定位件12凸出于浮动平台11的高度，减小换电装置1的高度尺寸，提升换电装置1的效率。
在一些实施例中，在步骤S300中，在定位孔21的轴向上，定位件12的保持在定位孔21内的部分的尺寸与定位孔21的尺寸之比k为0.2-0.95。
k的值越小，定位件12与定位孔21之间的配合尺寸越小，定位件12与定位孔21的孔壁之间的压强越大，定位件12受损的风险越高。k的值越大，定位孔21为定位件12预留的移动空间越小，定位件12因速率误差而碰撞定位孔21的底壁的风险越高。发明人经过计算和试验，将k的值限定在0.2-0.95，这样可以保证定位件12与定位孔21之间的配合尺寸，并使定位孔21为定位件12预留一定的移动空间，从而保证定位精度，并降低定位件12受损的风险。
在一些实施例中，在步骤S300中，定位件12保持在第一预定位置。
示例性地，在步骤S300中，V4的值等于0，定位件12在定位孔21 内保持静止。在浮动平台11到达第二预定位置之后，定位件12可以脱离第一预定位置。
在本实施例中，定位件12与定位孔21相对静止，以在引导浮动平台11朝向第二预定位置的移动的过程中，改善定位件12与定位孔21之间配合的稳定性，提高浮动平台11与用电设备2的对位精度。
在一些实施例中，步骤S400包括：S410、在浮动平台11移动到第二预定位置时，浮动平台11停止移动并支撑用电设备2的电池22；S420、安装于浮动平台11的解锁机构13解除电池22与用电设备2的用电主体23之间的锁定。
在本实施例中，浮动平台11可以带动解锁机构13靠近用电设备2，以便于解锁机构13解除电池22与用电设备2的用电主体23之间的锁定；浮动平台11可以在解锁电池22后支撑电池22，从而避免电池22摔落，提高安全性。
在一些实施例中，电池更换方法还包括：S600、在解除电池22与用电主体23之间的锁定之后，浮动平台11向下移动，以使电池22与用电主体23分离。
在本实施例中，浮动平台11可以在拆下电池22后下降，以降低换电装置1和电池22的高度，便于换电装置1向外运输电池22。
下面结合图2至图6简要描述本申请一具体实施例的电池更换方法的流程。
如图2所示，当用电设备2的电池22需要充电时，换电装置1移动到用电设备2的下侧。
如图3所示，换电装置1的浮动平台11向上移动以靠近用电设备2，同时，定位件12从初始位置相对于浮动平台11向上移动，直至定位件12到达第一预定位置。初始位置指的是定位件12在浮动平台11上的初始位置。
如图4所示，当定位件12插入用电设备2的定位孔21并到达第一预定位置后，浮动平台11继续向上移动，定位件12相对于浮动平台11向下移动，并使定位件12保持在第一预定位置。浮动平台11向上移动到第 二预定位置时停止，并支撑电池22。
如图5所示，解锁机构13运动并解除电池22与用电设备2的用电主体23之间的锁定。在解锁机构13运动的过程中，定位件12继续向下移动并逐渐脱离定位孔21。
如图6所示，在解锁机构13完成电池22的解锁后，浮动平台11向下移动。定位件12可以在解锁的过程中运动到初始位置，也可以在浮动平台11向下移动的过程中运动到初始位置。
在一些实施例中，在步骤S100中，浮动平台11上支撑有电池22。在浮动平台11移动到第二预定位置时，电池22卡接到用电设备2的用电主体23。
在本实施例中，浮动平台11可以举升电池22，以将电池22卡接到用电设备2的用电主体23，实现电池22的更换。

如图10所示，在电池22卡接于用电主体23后，浮动平台11向下移动，同时定位件12相对于浮动平台11向下移动，以运动到初始位置。

示例性地，本申请实施例的换电系统1000可按照下述步骤更换电池22：Ⅰ)当用电设备2进入换电平台3后，换电装置1可以移动到用电设备2的下侧，并将电能告罄的待充电的电池22从用电设备2上拆下；Ⅱ)换电装置1将拆下的待充电的电池22转运到电池仓4中，并接收电池仓4中的存储的满充电池22；Ⅲ)换电装置1带着满充电池22移动到用 电设备2的下侧，并将满充电池22安装到用电设备2上；Ⅳ)用电设备2离开换电平台3。
在一些实施例中，换电系统1000还包括轨道(未示出)，换电装置1可移动地设置于轨道。轨道用于引导换电装置1的移动，以使换电装置1能够在换电平台3和电池仓4之间移动。示例性地，轨道的一端延伸到电池仓4内，另一端延伸到换电平台3。
在一些实施例中，电池仓4中设置有堆垛机41，堆垛机41用于将换电装置1拆下的待充电的电池22转移到电池仓4的充电位进行充电，并将电池仓4存储的满充电池22放置在换电装置1上。
在一些实施例中，换电平台3包括举升机构，举升机构用于举升用电设备2，以便于换电装置1移动到用电设备2的下侧。
虽然已经参考优选实施例对本申请进行了描述，但在不脱离本申请的范围的情况下，可以对其进行各种改进并且可以用等效物替换其中的部件，尤其是，只要不存在结构冲突，各个实施例中所提到的各项技术特征均可以任意方式组合起来。本申请并不局限于文中公开的特定实施例，而是包括落入权利要求的范围内的所有技术方案。
