具体实施方式
为更进一步阐述本发明为达成预定发明目的所采取的技术手段及功效,以下结合附图及较佳实施例，对依据本发明提出的一种浮动装置、换电设备和换电站的具体实施方式及其功效，详细说明如后。
一种浮动装置，如图1所示，包括:固定底板1，浮动板2，悬挂立柱3和连接部4，其中，固定底板1和浮动板2面对面设置，浮动板2用于支撑目标物，所述目标物为待对准或定位的对象，例如，当所述浮动装置应用于换电站中的换电设备，如应用于换电小车时，所述目标物为电池包。浮动板2上设置有一对以上的悬挂立柱3，作为示例，每对悬挂立柱3可沿固定底板1的边缘面对面设置在浮动板2上。连接部4一端与悬挂立柱3相连接，另一端与固定底板1相连接；浮动板2可相对于固定底板1浮动。所述浮动装置结构简单，安装高度低，所占空间小，浮动板2可相对于固定底板1在水平面内沿任意方向浮动，且浮动范围大。
当浮动板2上的目标物不受外力作用，或是将目标物撤离浮动板时，浮动板2将通过自重回到初始位置，从而自动复位，下一个目标物置于浮动板2浮动时，所述浮动装置将会保持原有的浮动量。
如图1-图3所示示例，悬挂立柱3的一端设有横杆31，悬挂立柱3呈L型结构，连接部4的一端连接至横杆31。悬挂立柱3的另一端与浮动板2固定连接，具体可采用焊接、铆接、螺栓等方式固定连接。连接部4包括悬挂链条41和分别位于悬挂链条41两端的第一浮动连接结构42和第二浮动连接结构43，其中，第一浮动连接结构42连接横杆31，第二浮动连接 结构43与浮动板2浮动接触；当浮动板2相对于固定底板1浮动时，悬挂链条41随其摆动。由于悬挂链条41两端均采用浮动连接结构进行连接。该连接部3的组成机构可减小连接部2的长度，从而减小所述浮动装置所占空间，此外，还可保证使浮动板2可相对于固定底板1在水平面内沿任意方向浮动，且浮动范围大。
为了防止固定底板1和浮动板2直接接触摩擦力过大，进一步增加浮动板2相对于固定底板1的浮动范围，固定底板1和浮动板2之间设有浮动间隙5，连接部4还可包括连接板44，连接板44固定在所述浮动间隙5中，连接板44与固定底板1和浮动板2面对面设置，且连接板44上表面与固定底板1的上表面相接触，下表面与浮动板2的下表面相接触，需要说明的是，第二浮动连接结构43设于连接板44中，第二浮动结构43穿过连接板44与浮动板2下表面相接触，从而实现连接板4与浮动板2的浮动接触，使浮动板2可相对于连接板2和固定底板1在水平面内的任意方向浮动。需要说明的是，本示例以所述浮动装置以使用时所放置的状态为参考进行进行说明，此时以地面为底面，垂直于地面的方向为竖直方向，距离地面高的部件位于距离地面低的部件的上方，本示例中，浮动板2位于连接板44的上方，连接板44位于固定底板1的上方，本示例中的上、下、上表面、下表面等用于对本示例进行解释说明，并不仅限于此。
第一浮动连接结构42和第二浮动连接结构43均可包括一个或多个万向球结构来实现浮动连接，悬挂链条41两端的万向球结构背对背设置，即悬挂链条41两端的万向球结构的球面所朝部门相背设置。第一浮动连接结构1的万向球结构与横杆31可转动地连接，第二浮动连接结构43的万向球结构与连接板44可转动的连接，第二浮动连接结构43的万向球结构的球面穿过连接板44与浮动板2下表面相接触，浮动板2上表面用于放置目标物。
作为一种示例，固定底板1上设有与每一连接板44一一对应的，供连接部3穿过的卡槽11，卡槽11可以为U型槽、方形槽等，只需满足连接部3位于卡槽11中的部分能够随着浮动板2的浮动而摆动即可。如图5所示，悬挂链条41一端穿过卡槽11与第二浮动连接结构43相连接，连接板44卡接在固定底板1上。
浮动板2的结构并不仅限于传统的实体板状结构，还可设置为为框架结构，如图1和图5所实施例，这样既能满足支撑目标物的需求，也可以减轻所述浮动装置的重量，减少制造所述浮动装置所需材料，降低生产成本。
悬挂立柱设置3可设置在浮动板2的中间位置，如图1和图5所示示例，浮动板2上设置有两对悬挂立柱3，且两对悬挂立柱3分别设置在浮动 板2边缘的三等分点处，这样既可以减小固定底板的面积，节约生产成本，又可以防止所述浮动装置所在换电设备的其他部件与所述悬挂立柱3发生干涉，例如，浮动板2为矩形结构，悬挂立柱3分布在浮动板2的四个顶点处，而通常换电设备会在该位置或该位置附近设置定位结构等部件，此时可能会对定位结构等部件发生干涉等现象。因此，悬挂立柱设置3设置在浮动板2的中间位置，会使换电设备和换电站的设计及布局更加灵活。
在一些示例中，所述浮动装置还包括锁紧部(图中未示出)，锁紧部可设置一个或多个，用于当目标物调整到目标位置时，锁紧浮动板2，使浮动板2相对于固定底板1不可移动，以便对目标物进行相应的操作，例如所述浮动装置设置在换电设备上，当将电池包的位置对准换电位置以后，通过锁紧部锁紧浮动板2，从而电池包位置也固定，进而可以进行换电操作，通过所述装置提高了换电设备的换电精度和准确性。作为一种示例，所述浮动装置可包括4个锁紧部，沿周向均匀分布在固定底板1的周围，从而使锁紧过程中，浮动板2保持平稳状态，避免目标物的位置出现微小移动，提高对目标位定位和对准的准确性，进一步提高换电过程的准确性。
所述锁紧部可以为电磁刹车吸盘，设置在浮动板2上方，刹车吸盘朝向固定底板1，固定底板1作为刹车吸盘的吸合面。浮动板2上设有与刹车吸盘相对应的通孔，锁紧过程中，刹车吸盘穿过所述通孔吸附所述固定底板1，从而锁紧浮动板2。可通过对电磁刹车吸盘通电或断电，控制电磁刹车吸盘吸附或松开固定底板1。在松开状态下，锁紧部可跟随浮动板2的浮动进行浮动。所述电磁刹车吸盘也可以直接选用现有的成品，因此具体结构组成在此不再赘述。需要说明的是，锁紧部采用电磁刹车吸盘仅为一种实施例，在其他实施例中也可采用其他锁紧部，在目标物达到预设位置时，锁紧浮动板2即可。
本发明实施例还提供了一种换电设备M，换电设备M为换电站中的一个组成部分，用于运送和更换电池包，例如可以为换电小车。如图6所示，换电设备M可包括本发明实施例所述定位装置N。换电过程中，电池包置于浮动装置M上，在换电位置不准确的情况下，推动电池包，进而带动浮动盘浮动，从而调整电池包的位置。
本发明实施例还提供了一种换电站，包括一个或多个本发明实施例所述换电设备M。
本发明实施例所述浮动装置结构简单，安装高度低，所占空间小；连接部4两端采用浮动连接结构，使浮动板2可相对于固定底板1在水平面内沿任意方向浮动，且浮动范围大。
以上所述，仅是本发明的较佳实施例而已，并非对本发明作任何形式上的限制，虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发 明,任何熟悉本专业的技术人员，在不脱离本发明技术方案范围内,当可利用上述揭示的技术内容作出些许更动或修饰为等同变化的等效实施例,但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本发明技术方案的范围内。
