附图说明
以下将结合附图和具体实施方式，对本发明的技术方案作进一步的详细描述，其中：
图1是本发明的电控磁性连接装置的第一具体实施方式在开启状态下的结构示意图；
图2是图1的电控磁性连接装置在关闭状态下的结构示意图；

具体实施方式
以下结合附图对本发明的具体实施方式进行详细说明。首先，需要说明 的是，在本说明书中提到或可能提到的上、下、左、右、前、后、内侧、外侧、顶部、底部等方位用语是相对于各附图中所示的构造进行定义的，它们是相对的概念，因此有可能会根据其所处不同位置、不同使用状态而进行相应地变化。所以，也不应当将这些或者其他的方位用语解释为限制性用语。
图1中示出了本发明的电控磁性连接装置的一个具体实施方式。从图1可见，该电控磁性连接装置由电机10、第一磁体20、第二磁体30等部件组成，其中，第一磁体20布置在所述电控磁性连接装置的外壳上，而第二磁体30布置在所述第一磁体20附近并且通过电机10驱动而能相对于所述第一磁体20转动，使得所述第一磁体20和所述第二磁体30的磁极的相对位置发生变化。优选地，所述第一磁体20和所述第二磁体30是永磁体。
在图1所示的实施例中，所述电控磁性连接装置包括由蜗轮40和蜗杆50构成的传动装置，其中，所述第二磁体30安装在所述蜗轮40上，而所述蜗杆50由所述电机10驱动而转动。在所述电控磁性连接装置工作时，先由所述电机10驱动所述蜗杆50，再由所述蜗杆50驱动所述蜗轮40带动所述第二磁体30旋转，从而使第二磁体30和第一磁体20的磁极相对位置发生变化。
接下来将重点介绍上述实施例中的电控磁性连接装置的工作原理。所述电控磁性连接装置包括开启状态和关闭状态，在所述开启状态中，所述第一磁体20与所述第二磁体30的同侧磁极相同，用于对铁磁性物件产生吸力，使得整个机构对外产生强大磁力，特别是对铁磁性物件60产生吸引力，如图1所示；而在所述关闭状态中，所述第一磁体20和所述第二磁体30的同侧磁极相反，使得整个机构对外呈弱磁性，即不对铁磁性物件60产生吸引力，如图2所示。优选地，在所述开启状态和所述关闭状态中，所述第一磁体20和所述第二磁体30布置在同一直线上。当然，本领域技术人员可以理解的是，所述电控磁性连接装置还包括中间状态，在所述中间状态中，所述第一磁体20与所述第二磁体30的同侧磁极的呈某一夹角布置，如图3所示。简而言之，所述开启状态与所述关闭状态之间的切换通过电机10驱动蜗杆50，然后蜗杆50再驱动蜗轮40，使得第二磁体30相对于第一磁体20旋转180度，从而达到所述开启状态与所述关闭状态两种状态的切换。
图4示出了本发明的电控磁性连接装置的另外一个具体实施方式。从图4 可见，该电控磁性连接装置由电机110、第一磁体120、第二磁体130等部件组成，其中，第一磁体120布置在所述电控磁性连接装置的外壳上，而第二磁体130布置在所述第一磁体120附近并且通过电机110驱动而能相对于所述第一磁体120转动，使得所述第一磁体120和所述第二磁体130的磁极的相对位置发生变化。需要指出的是，在图4中示出的实施例中，所述电机110是带有自锁功能的步进电机。可选地，所述第二磁体130可以直接安装在所述步进电机上。
以下将具体描述如图4所示的实施例的电控磁性连接装置的工作原理。所述电控磁性连接装置包括开启状态和关闭状态，在所述开启状态中，所述第一磁体120与所述第二磁体130的同侧磁极相同，用于对铁磁性物件160产生吸力，使得整个机构对外产生强大磁力，特别是对铁磁性物件160产生吸引力，如图4所示；而在所述关闭状态中，所述第一磁体120和所述第二磁体130的同侧磁极相反，使得整个机构对外呈弱磁性，即不对铁磁性物件160产生吸引力，如图5所示。优选地，在所述开启状态和所述关闭状态中，所述第一磁体120和所述第二磁体130布置在同一直线上。当然，本领域技术人员可以理解的是，所述电控磁性连接装置还包括中间状态，在所述中间状态中，所述第一磁体120与所述第二磁体130的同侧磁极的呈某一夹角布置，如图6所示。简而言之，所述开启状态与所述关闭状态之间的切换通过固定在电机110上的第二磁体130相对于第一磁体120旋转180度，从而达到所述开启状态与所述关闭状态两种状态的切换。
此外，本发明还提供了一种电动汽车电池更换设备，所述电动汽车电池更换设备包括上述的电控磁性连接装置。进一步地，所述铁磁性物件固定在待被更换的电池上。
综上所述，本发明的电控磁性连接装置不仅结构简单、操作易行，而且能够根据需求进行自动化控制和远程控制。因此十分推荐将这种电控磁性连接装置应用于电动汽车电池更换设备中。
以上列举了若干具体实施方式来详细阐明本发明的电控磁性连接装置，以及设置有该电控磁性连接装置的电动汽车电池更换设备，这些个例仅供说明本发明的原理及其实施方式之用，而非对本发明的限制，在不脱离本发明的精神和范围的情况下，本领域的普通技术人员还可以做出各种变形和改进。例如，所述第一磁体和所述第二磁体的大小形状相同。因此，所有等同的技术方案均应属于 本发明的范畴并为本发明的各项权利要求所限定。
