现结合图1至图4，对本申请提供的各实施例进行描述，应当理解的是，以下仅是本申请的示意性实施方式，并不对本申请构成任何特别限定。
图1是根据本申请的一个实施例提供的一种换电站的结构示意图；图2是根据本申请的另一实施例提供的一种换电站的结构示意图，请参见图1至图2。该换电站包括：至少一对换电组件100，每一对换电组件100即是两个换电组件100。其中，每一对中的两个换电组件100间隔设置，每一对中的两个换电组件100之间形成换电通道200，以供待换电车辆行驶、停驻和更换电池。
上述的每个换电组件100包括：换电装置120和多个电池仓110。其中，换电装置120用于在电池仓110与待换电车辆之间转移换电电池。上述的换电电池可以为待换电车辆中的亏电电池或电池仓110中的满电电池，并且更换电池的过程可以是：在待换电车辆行驶至换电换电通道200中之后，通过两侧的任意一个换电装置120卸载待换电车辆中的亏电电池，之后仍可以通过两侧的任意一个换电装置120将从电池仓110中获取的满电电池装载到待换电车辆上， 完成换电过程。可见，这种结构的换电站不仅能够配置数量更多的电池，容错能力也好，在一个换电装置120故障的情况下，一对换电组件100中的另一个换电装置120仍能满足使用。
本申请提供的换电站，通过设置至少一对换电组件100，使待换电车辆可以通过两侧的任意一个换电装置120进行换电。换电站不仅能够配置数量更多的电池，也提高了容错能力，在一对换电组件100中的一个换电装置120故障的情况下，另一个换电装置120仍能满足使用。
另外，上述的换电站还满足了一些仅能在一侧换电的车辆的需要，具有较高的实用性。在建设方面，本申请提供的换电站可以分两期建设。第一期先建设包括换电通道和一个换电组件100，若换电需求旺盛，则第二期在换电通道另一侧增加一个换电组件100，双侧换电组件100共用一个换电通道，减小占地面积，有效利用土地。
在上述的实施例中，该换电组件100的数量可以为一对或多对。在换电组件100的数量为一对时，这一对中的两个换电组件100之间形成换电通道200。
在换电组件100的数量为多对时，多对换电组件100之间具一定间隔。该换电站可以同时为与换电组件100的对数相等的车辆进行换电，大大提高了换电效率。这种换电站的结构可以适用于多个待换电车辆集中换电的情况，可以提高换电速度。
在本申请提供的一个实施例中，多个电池仓110以弧形围绕换电装置120布置，且多个电池仓110形成的弧形具有开口130。该开口130用于使换电装置120能够经由开口130在电池仓110与待换电车辆之间转移换电电池。
在这种结构中，换电装置120通过转动即可切换为与不同的电池仓110对应，以便快速从对应的电池仓110中抓取换电电池或在电池仓110中放置换电电池，有利于节省工作时间。而且，这种结构中电池仓110与换电装置120之间的距离相对较小，能够进一步缩减换电装置120与电池仓110之间更换电池的时间。其中，上述的弧形可以是圆形或椭圆形的一部分，本实施例对此不作 限定。
当然了，上述换电组件100中的电池仓110还可以是其他排列形式，例如，各个电池仓110排成一排，换电装置120通过移动至各电池仓110前，实现从电池仓110中抓取换电电池或在电池仓110中放置换电电池，本实施例对此不作限定。
在上述实施例中，每一对换电组件100对称设置，并且每一对中的两个换电组件100的电池仓110的开口130彼此相对。也就是说上述的开口130均开设在具有换电通道200的一侧，以便换电装置120对换电通道200中的待换电车辆进行换电。
在本申请提供的一个实施例中，上述的换电装置120包括：底座121和至少一个抓取单元122。其中，上述的抓取单元122均设置在底座121上。该底座121用于支撑上述的抓取单元122，并且能够带动抓取单元122转动。通过抓取单元122的转动，改变抓取单元122的位置，便于抓取单元122实现抓取动作。例如，在待换电车辆行驶至换电通道200中时，通过转动底座121，使空置的抓取单元122转动至开口130处，以便通过该抓取单元122来卸载亏电电池。继续转动底座121，将设置有满电电池的抓取单元122转动至开口130处，以便抓取单元122将满电电池装载至待换电车辆上。
而且，在一个换电组件100中，多个电池仓110围绕所述换电装置120布置，所述抓取单元122通过转动能够对应于其中任意一个电池仓110，以从所对应的电池仓110中取放电池。
其中，抓取单元122的数量可以为一个、两个或两个以上，下面对此分别进行介绍。
第一种：请参见图1和图3，抓取单元122的数量为两个，两个抓取单元122并排设置，且两个抓取单元122的抓取方向相反。其中，抓取方向是指抓取单元122向外伸出以便抓取换电电池的方向。由于上述的两个抓取单元122是并排设置的，为了保证底座121承重的平衡，两个抓取单元122是中心对称 的，也即是说，底座121的转动中心对应在两个抓取单元122之间。对应的，其中一个抓取单元11转动至与其中任意一个电池仓110对应时，所对应的电池仓110的中心线偏离底座121的转动中心，并且所对应的电池仓110的中心线与转动中心之间的距离S等于抓取单元122的中心线与转动中心之间的距离L(请参见图3)。也就是说，在其中一个抓取单元122转动至与某个电池仓110对应时，该抓取单元122的中心线与该电池仓110的中心线重合，使该抓取单元122与该电池仓110在轴向完全对应，以便抓取单元122可以便捷的抓取换电电池仓110中的电池或在电池仓110中放置电池。
第二种：请参见图2，在本申请提供的一个实施例中，抓取单元122的数量为一个，该抓取单元122的中心线穿过底座121的转动中心，对应的，各个电池仓110的中心线也穿过底座121的转动中心。也即是说，在抓取单元122转动至与某个电池仓110对应时，该抓取单元122的中心线与该电池仓110的中心线重合，使抓取单元122与该电池仓110在轴向完全对应，以便抓取单元122可以便捷的抓取换电电池仓110中的电池或在电池仓110中放置电池。
第三种：抓取单元122的数量为两个以上，这些抓取单元122是均匀布置的，而且抓取方向各不相同。并且电池仓110的中心线与转动中心之间的距离等于抓取单元122的中心线与转动中心之间的距离。也就是说，在抓取单元122转动至与某个电池仓110对应时，该抓取单元122的中心线与该电池仓110的中心线重合，使抓取单元122与该电池仓110在轴向完全对应，以便抓取单元122可以便捷的抓取换电电池仓110中的电池或在电池仓110中放置电池。
在一个实施例中，任意一个换电组件100中，多个电池仓110中至少有一个空仓位，用于承托从待换电车辆中卸载下来的换电电池。该抓取单元122可以独立使用，在使用时，先将待换电车辆上的亏电电池卸载至空仓位中，再从电池仓110中抓取满电电池，更换到待换电车辆上。一对换电组件100中的抓取单元122也可以配合使用，例如，一个换电装置120用来卸载待换电车辆上的亏电电池，另一个换电装置120用来装载满电电池，可以提高换电效率。
图4是本申请的一个实施例提供的一种换电站中换电装置的结构示意图。请参见图4，在该实施例中，抓取单元122包括：悬臂座1221、挠性件1222、浮动吊架1223、动力件以及连接组件。其中，悬臂座1221的第一端设置在底座121上，悬臂座1221用于对抓取单元122中的其他组件起到支撑作用。浮动吊架1223通过挠性件1222连接在悬臂座1221的第二端，挠性件1222是指可弯曲的连接件，在运动中可承受拉力，例如，钢丝绳、钢丝带等。上述动力件的输出端连接挠性件1222，用于驱动挠性件1222收放，从而带动浮动吊架1223的移动。另外，挠性件1222的运用也使得浮动吊架1223在水平面内可以移动，从而便于浮动吊架1223与换电电池的连接。具体的，上述的连接组件设置在浮动吊架1223的底部，用于连接换电电池。
在本申请提供的一个实施例中，挠性件1222的数量为4个，4个挠性件1222分别设置在浮动吊架1223的四角，以便使浮动吊架1223受力均匀，提高吊装换电电池过程中的换电装置120的平稳性。
在本申请提供的一个实施例中，上述的底座121上设置有至少一组第一导轨123，每组第一导轨123上设置有一个抓取单元122，且该抓取单元122可沿第一导轨123移动，因此，第一导轨123的延伸方向与抓取方向重合。通过抓取单元122沿第一导轨123移动，使得抓取单元122靠近电池或远离换电电池。
上述的换电装置120还包括：第二导轨124，该底座121可移动的设置在第二导轨124上，以便底座121可以沿第二导轨124移动，并带动对应的抓取单元122移动。
其中，第二导轨124和第一导轨123垂直设置，抓取单元122相对于第二导轨124可沿两个互相垂直的方向移动。又由于抓取单元122与底座121之间是可相对转动的，因此抓取单元122在水平面内可自由移动，具有较高的自由度，便于定位和抓取换电电池。
在本申请提供的一个实施例中，该换电站还包括限位结构210，该限位结构210位于换电通道200中，用于对待换电车辆进行限位，以使待换电车辆的 换电电池与换电装置120对应。
具体的，在待换电车辆行驶进入换电通道200中时，通过限位结构210的限位，使待换电车辆可以停在与换电装置120对应的位置，以便换电。该限位结构210的具体结构可以根据需要设置，例如，可以为凸起或凹槽等，本实施例对此不作限定。
本申请提供的换电站，通过设置至少一对换电组件100，使待换电车辆可以通过两侧的任意一个换电装置120进行换电。换电站不仅能够配置数量更多的换电电池，也提高了容错能力，在一个换电装置120故障的情况下，一对换电组件100中的另一个换电装置120仍能满足使用。
进一步的，上述的多个电池仓110以弧形围绕在换电装置120外，且多个电池仓110形成的弧形具有开口130。该开口130用于使换电装置120能够经由开口130在电池仓110与待换电车辆之间转移换电电池。在这种结构中，换电装置120通过转动即可在不同的电池仓110之间切换，以便快速从电池仓110中抓取换电电池或在电池仓110中放置换电电池，有利于节省工作时间。而且，这种结构中电池仓110与换电装置120之间的距离相对较小，能够进一步缩减换电装置120与电池仓110之间更换电池的时间。
在上述实施例中，待换电车辆可以是车辆，比如电动重卡；也可以是工程机械，比如电动挖掘机、电动起重机、电动自卸车、电动装载机、电动压实机等，本实施例对此不作限定。
最后应说明的是：以上实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的精神和范围。
