具体实施方式
下面结合附图，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下述的实施例范围之中。
如图1-5所示，换电设备10包括：底盘11、固定盘12、移动盘13和多个弹性托件14。
固定盘12在上下方向上设于底盘11和移动盘13之间，固定盘12相对于底盘11固定，移动盘13滑设于固定盘12。如图5所示，固定盘12上设置有四个导轨122，导轨122上设有滑块123，该滑块123固定于移动盘13，从而移动盘13滑设于固定盘12。
换电设备10还包括驱动件15，驱动件15用于驱动移动盘13在水平方向上移动即使得移动盘13沿着导轨122滑动。
固定盘12设有一缺口121，驱动件15设于底盘11上并穿过缺口121连接移动盘13。缺口121的大小设置为驱动件15可以在缺口121中移动一定距离，以使得移动盘13可以在导轨122的长度范围内移动。驱动件15优选为直线电机。
移动盘13设于底盘11上方并相对于底盘11在水平方向上可移动，移动盘13用于托举电池。多个弹性托件14分布于移动盘13的上表面上。并且弹性托件14分布于移动盘13的边缘部分，特别是分布于移动盘13的四个角。弹性托件14分布于移动盘13的边缘部分有利于更好地支撑电池。
当然，可选择地，弹性托件14也可以不设置在边缘部分而是设置在移动盘13的中心部分。
弹性托件14包括弹性件141和抵接片142，弹性件141连接于抵接片142与移动盘13的上表面之间。设置有抵接片142，从而避免弹性件141直接接触电池而损坏电池。在本实施例中，抵接片142为圆片。可选择地，抵 接片142的形状也可以是方形、菱形、矩形、椭圆形、六边形等等。抵接片142的材料可以是刚性或柔性材料，例如塑料片或橡胶片等等。弹性件141一般为弹簧。可选择地，弹性件141也可以是盘簧、弹力足够的橡胶垫等等。抵接片142和弹性件141之间可以通过粘接、焊接、机械连接等等方式进行连接。
移动盘13为一片式结构。一片式结构避免了上下层之间的力矩传递。
换电设备10还包括用于卡住车体的第一卡件16和用于卡住电池的第二卡件17，第一卡件16和第二卡件17分别设于固定盘12和移动盘13上。移动盘13和固定盘12的形状和大小大致相同，但是移动盘13的一端向内缩进一凹部131，从而在移动盘13与固定盘12几乎完全重叠时(如图2所示)，不会干涉设于固定盘12上的第一卡件16。
在换电设备10工作时，第一卡件16卡住车体，第二卡件17卡住电池，然后移动盘13水平移动以将电池卸下或装上。
换电设备10还包括解锁机构18，解锁机构18设于移动盘13上。解锁机构18用于将电池从车体上解锁。
换电设备10还包括基座19和顶升机构(未示意)，顶升机构连接基座19和底盘11并能够相对于基座19顶升底盘11。
该换电设备10可以应用于各类换电站，例如集装箱换电站等。
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作出多种变更或修改，但这些变更和修改均落入本发明的保护范围。
