可选地，每一个所述滚轮安装座分别对应有一个所述驱动装置，每一个所述驱动装置的一部分都位于所述底座本体的前侧，以供操作人员操作；并且/或者，所述底座还包括至少一个支脚，所述支脚与所述底座本体螺纹连接，所述支脚被拧动时能够朝着远离所述底座本体的方向移动，并能够与所述承载表面抵接，以将所述底座本体顶起，从而使与所述支脚靠近的所述滚轮脱离所述承载表面。
本发明在第二方面提供了一种电器设备，所述电器设备包括第一方面中任一项所述的底座，所述电器设备为冰箱、冰柜、冷柜或衣物处理设备。
基于前文的描述，本领域技术人员能够理解的是，在本发明前述的技术方案中， 通过在底座本体上设置枢转的滚轮安装座，在滚轮安装座上安装滚轮，并通过驱动装置驱动滚轮安装座相对于底座本体摆动，使得滚轮朝着靠近或远离底座本体的方向移动，从而调整底座本体与承载表面(地面)之间的距离。因此，本发明的底座不仅可以通过滚轮来支撑电器设备移动，而且还能够通过驱动装置来调整底座本体与承载表面(地面)之间的距离，从而能够防止电器设备歪斜。
进一步，通过使第一驱动构件和第二驱动构件中的一个具有螺纹孔，使第一驱动构件和第二驱动构件中的另一个具有螺纹柱，使得第一驱动构件和第二驱动构件能够以螺纹的方式啮合到一起。通过使具有操作部的第一驱动构件与底座本体相连接，使第二驱动构件与滚轮安装座连接，使得操作部被操作时，能够驱动第一驱动构件转动，进而使螺纹柱朝着伸入或伸出螺纹孔的方向移动，以改变第一驱动构件和第二驱动构件的长度，从而驱动滚轮安装座相对于底座本体摆动。因此，本发明的底座仅需使用户拧动操作部，就可调整底座的高度，调整更加方便。
进一步，通过使锁紧帽与操作部可拆卸地安装到一起，锁紧帽通过磁体吸附到底座本体上，并因此使防滑结构与防滑配合结构匹配到一起，使得操作部被周向固定，从而防止了操作部在电器设备工作的过程中发生转动，保证了电器设备工作时姿态的稳定性。
进一步，通过在螺纹孔内填充润滑脂，以及在滚轮与承载表面抵接时，使螺纹孔倾斜向下，使得螺纹孔内的润滑脂在自身重力的作用下流动到螺纹柱，从而对螺纹柱与螺纹孔之间的螺纹进行润滑，不仅降低了第一驱动构件和第二驱动构件相对移动时的摩擦力，而且还降低了第一驱动构件和第二驱动构件螺纹部分生锈的几率。
再进一步，通过使每一个驱动装置的一部分都位于底座本体的前侧，方便了操作人员(例如用户)对每一个滚轮安装座的调节，提升了用户的使用体验。
根据下文结合附图对本发明具体实施例的详细描述，本领域技术人员将会更加明了本发明的上述以及其他目的、优点和特征。

下面参照图1至图7，来对本发明第一实施例中可移动的底座进行详细说明。其中，图1是本发明第一实施例中底座的结构分解图，图2是本发明第一实施例中底 座的第一轴测视图，图3是本发明第一实施例中底座的第二轴测视图，图4是本发明第一实施例中滚轮相关部分的轴测视图，图5是本发明第一实施例中滚轮相关部分的结构分解图，图6是本发明第一实施例中滚轮与承载表面分离时的状态示意图，图7是本发明第一实施例中滚轮与承载表面接触时的状态示意图。
如图1至图3所示，在本发明的第一实施例中，可移动的底座100包括底座本体110、滚轮安装座120、滚轮130、驱动装置140和可选的支脚150。滚轮安装座120枢转地安装到底座本体110上。滚轮130可转动地安装到滚轮安装座120上。驱动装置140用于驱动滚轮安装座120相对于底座本体110摆动，以使滚轮130朝着靠近或远离底座本体110的方向移动，从而调整底座本体110与承载表面200(如图6和图7所示)之间的距离。支脚150与底座本体110螺纹连接。支脚150被拧动时能够朝着远离底座本体110的方向移动，并能够与承载表面200(如图6和图7所示)抵接，以将底座本体110顶起，从而使与支脚150靠近的滚轮130脱离承载表面200(如图6和图7所示)。
继续参阅图1至图3，底座100的四个边角处分别设置有一个滚轮安装座120，每一个滚轮安装座120分别对应有一个滚轮130和一个驱动装置140。此外，本领域技术人员也可以根据需要，将底座100上滚轮安装座120的安装位置和数量进行适当调整，以及将每一个滚轮安装座120对应的滚轮130的数量进行适当调整。例如，为底座100配置三个滚轮安装座120，并使该三个滚轮安装座120分别布置在底座100的正前方、左后方和右后方。进一步，本领域技术人员也可以根据滚轮安装座120的分布情况，对底座100的形状进行相应的调整。示例性地，如果所有的滚轮安装座120分布成三角形，则将底座100的形状设置为三角形。如果所有的滚轮安装座120分布成四角形，则将底座100的形状设置为四角形(四边形)。如果所有的滚轮安装座120分布成五角形，则将底座100的形状设置为五角形。
如图1所示，底座本体110上设置有转轴卡槽111和安装腔112。该转轴卡槽111用于固定滚轮安装座120，安装腔112用于安装驱动装置140。
如图4至图7所示，滚轮安装座120的转轴121安装到转轴卡槽111内，并且转轴121与水平面大致平行，以便滚轮安装座120能够绕该转轴上下摆动。
继续参阅图4至图7，驱动装置140包括驱动连接到一起的第一驱动构件141和第二驱动构件142。该第一驱动构件141与底座本体110相连接，第二驱动构件142与滚轮安装座120连接。第一驱动构件141与第二驱动构件142配置成能够相对移动，以驱动滚轮安装座120相对于底座本体110摆动。
如图5所示，第一驱动构件141包括螺纹孔1411和操作部1412，第二驱动构件142包括螺纹柱1421。该螺纹孔1411与螺纹柱1421相匹配。操作部1412是裸露在底座本体110前侧的柱体。如图5所示地，操作部1412是六边形的柱体。此外，本领域技术人员也可以根据需要，将操作部1412设置为其他任意可行的、横截面为非圆形的结构，例如三角柱、椭圆柱、四边形柱等。优选地，第一驱动构件141是具有螺纹孔1411的螺栓。
此外，本领域技术人员也可以根据需要，将操作部1412设置成裸露在底座本体110前侧的沉槽，并且该沉槽的横截面为非圆形，例如六边形沉槽、三角形沉槽、椭圆沉槽、矩形沉槽等。
继续参阅图5，第二驱动构件142整体上呈L型，为了方便说明，这里将第二驱动构件142上具有螺纹柱1421的一段记作螺纹段，将第二驱动构件142上没有螺纹柱1421的一段记作连接段。第二驱动构件142通过该连接段与滚轮安装座120枢转连接到一起。
如图6和图7所示，操作部1412被操作时，驱动第一驱动构件141转动，进而使螺纹柱1421朝着伸入或伸出螺纹孔1411的方向移动，以改变第一驱动构件141和第二驱动构件142的长度，从而驱动滚轮安装座120相对于底座本体110摆动。
此外，在本发明的其他实施例中，本领域技术人员也可以根据需要，在第一驱动构件141上设置螺纹柱，并在第二驱动构件142上设置与该螺纹柱相匹配的螺纹孔。
下面参照6和图7，来对驱动装置140的使用方法和工作原理进行详细说明。
当底座100的某一个滚轮130如图6所示地与承载表面200分离，被悬空时，操作人员通过拧动(具体可以借助扳手)操作部1412，来使第二驱动构件142的螺纹柱1421拧入第一驱动构件141的螺纹孔1411内，从而使第一驱动构件141和第二驱动构件142的长度变短，进而使图6中所示的滚轮安装座120逆时针转动。转动的滚轮安装座120会使滚轮130逐渐靠近承载表面200，直至与承载表面200抵接。随着操作人员继续拧动操作部1412，该滚轮安装座120会逐渐将其对应底座100上的部分顶起。
当底座100的某一个滚轮130对应底座100上的部分较高时，操作人员反向拧动操作部1412，来使第二驱动构件142的螺纹柱1421旋出第一驱动构件141的螺纹孔1411，从而使第一驱动构件141和第二驱动构件142的长度变长，进而使图6中所示的滚轮安装座120顺时针转动。在此过程中，由于底座100的重力作用，会使 滚轮130始终与承载表面200抵接。当滚轮130与承载表面200之间的压力为零时，随着继续拧动操作部1412，滚轮130可以与承载表面200分离。
由此可见，滚轮安装座120主要是通过驱动装置140的拉力和底座100的重力来迫使其摆动。
进一步，虽然图中并未示出，但是为了方便第一驱动构件141与第二驱动构件142之间的相对移动，本领域技术人员也可以根据需要，在螺纹孔1411内填充有润滑脂。并在滚轮130与承载表面200抵接时，使螺纹孔1411倾斜向下，以使螺纹孔1411内的润滑脂在自身重力的作用下流动到螺纹柱1421，从而对螺纹柱1421与螺纹孔1411之间的螺纹进行润滑。本领域技术人员能够理解的是，由于油脂具有粘性，所以在第一驱动构件141与第二驱动构件142相对移动的过程中，彼此啮合的螺纹都会粘附油脂。
进一步，从图6和图7中可以看出，在滚轮安装座120和滚轮130将底座本体110顶起的过程中，滚轮130与滚轮安装座120之间的扭矩逐渐变小，这就使得底座100在其上物体(例如冰箱、洗衣机)较重时，也能够使操作人员轻松地拧动操作部1412。尤其是，逐渐减小的扭矩能够抵消掉底座100上物体上升时的加速度。
其中，滚轮130与滚轮安装座120之间的扭矩指的是，“底座100及其上的物体作用到滚轮130的转轴上的力”与“转轴121与滚轮130的转轴之间在水平方向上的距离”的乘积。
同时，第一驱动构件141和第二驱动构件142之间啮合的螺纹能起到杠杆的作用，使操作人员仅需要很小的力气就能够拧动操作部1412，从而将底座本体110顶起。因此，本发明的底座100实现了二次省力，提升了用户的使用体验。
返回去继续参阅图1至图3，底座100包括两个支脚150，该两个支脚150设置在底座100的前侧，并且分别对应一个滚轮安装座120。此外，本领域技术人员也可以根据需要，将支脚150设置成其他任意可行的数量。例如一个、三个、四个等。
在本发明的第一实施例中，当底座100需要移动时，正向拧动支脚150，以使支脚150与承载表面200分离，以便使与支脚150靠近的滚轮130与承载表面200抵接。当底座100不需要移动时，反向拧动支脚150，以使支脚150与承载表面200抵接，将底座本体110顶起，从而使与支脚150靠近的滚轮130脱离承载表面200。
下面参照图1、图5至图7，来底座100的组装过程进行简单说明。
底座100在组装时，先将滚轮安装座120和滚轮130安装到一起，然后将滚轮安装座120从底座本体110的下方安装，以使滚轮安装座120嵌入到开口朝下的转 轴卡槽111中。然后，从安装腔112将第二驱动构件142插入到滚轮安装座120上，再使第一驱动构件141穿过设置在底座本体110前侧上的孔，并使第一驱动构件141和第二驱动构件142螺纹连接到一起。最后，再将支脚150拧到底座本体110上的螺纹孔(图中未示出)中。
需要说明的是，底座100前述的组装顺序并非固定不变，本领域技术人员可以根据实际情形，对底座100各部件之间的组装顺序进行调整。
基于前文的描述，本领域技术人员能够理解的是，在本发明的第一实施例中，通过驱动装置140来驱动滚轮安装座120摆动，使得相应的滚轮130能够靠近或远离底座本体110，从而实现了对每个滚轮130高度的调节。因此，本发明的底座100不仅可以通过滚轮130来移动，而且还能够通过驱动装置140来调整底座本体110与承载表面200之间的距离，从而能够防止底座100歪斜。
进一步，在本发明的第一实施例中，支脚150的设置，还能够防止底座100移动，对底座100进行固定。
再进一步，通过将所有的驱动装置140的操作部1412都设置在底座100的前侧，方便了操作人员对驱动装置140的调节，优化了用户的使用体验。
下面参照图8来对本发明的第二实施例中的底座100进行说明。
如图8所示，与第一实施例相比，本发明第二实施例中的底座100还包括锁紧帽160。该锁紧帽160用于对驱动装置140进行锁定，以防止驱动装置140因振动而松动，从而导致滚轮安装座120摆动。具体地，锁紧帽160上设置有磁体161和防滑结构162。该防滑结构162设置在锁紧帽160面向底座本体110的一侧。并且锁紧帽160能够与驱动装置140的操作部1412嵌合到一起。例如，锁紧帽160通过图8中所示的六边形孔结构与图5和图6所示六边形柱形式的操作部1412嵌合到一起。
继续参阅图8，与锁紧帽160相应地，底座本体110上设置有防滑配合结构113，该防滑配合结构113与防滑结构162相匹配。可选地，防滑结构162和防滑配合结构113都是防滑纹。底座本体110与锁紧帽160相对应的部分设置为能够被磁体161吸引的形式。例如，在底座本体110与锁紧帽160相对应的位置处设置一个铁片。
在装配好的状态下，锁紧帽160与操作部1412以可拆卸的形式安装到一起，锁紧帽160通过磁体161吸附到底座本体110上，并因此使防滑结构162与防滑配合结构113匹配到一起，以防止第一驱动构件141松动。
在需要调整驱动装置140时，操作人员仅需要将锁紧帽160从操作部1412上拔下即可。
基于前文的描述，本领域技术人员能够理解的是，在本发明的第二实施例中，底座100能够通过锁紧帽160对驱动装置140进行锁定，防止驱动装置140使滚轮安装座120发生异常的摆动，从而保证了底座100在长久使用时的稳定性。
下面参照图9来对本发明的第三实施例中的底座100进行说明。
如图9所示，与第一、第二实施例相比，在本发明第三实施例中，底座本体110的结构做了相应改变。具体地，底座本体110通过避让结构114替代了安装腔112。
在底座100组装的过程中，滚轮安装座120同样地从底座本体110的底侧，使转轴121嵌入到转轴卡槽111中。然后，操作人员从避让结构114将第一驱动构件141插入到滚轮安装座120内。
从图9和图1中可以看出，在本发明的第三实施例中，避让结构114能够使第一驱动构件141的安装过程可视化，提升了操作人员的组装效率。
下面参照图10来对本发明的第四实施例中的底座100进行说明。
如图10所示，与第一、第二、第三实施例相比，在本发明第四实施例中，驱动装置140包括啮合的丝杠143和丝杠螺母144，丝杠143与底座本体110周向可转动并且轴向固定地连接到一起，丝杠螺母144与滚轮安装座120枢转连接。进一步，丝杠143包括与丝杠螺母144啮合的丝杠段1431和裸露在底座本体110外侧的操作结构1432。
操作结构1432被操作时，丝杠143驱动丝杠螺母144移动，以使滚轮安装座120相对于底座本体110摆动。
此外，在本发明的第五实施例中，本发明还提供了一种电器设备。下面参照图11来对本发明的电器设备进行说明。
如图11所示，在本发明的第五实施例中，电器设备300包括设备本体310和底座100，该底座100可以是前文任一实施例中所描述的底座。
进一步，设备本体310和底座100可以固定连接为一个整体，也可以通过可拆卸的方式固定到一起。
可选地，电器设备300可以是冰箱、冰柜、冷柜或衣物处理设备。该衣物处理设备可以是洗衣机洗衣机、干衣机或洗干一体机。
基于前文的描述，本领域技术人员能够理解的是，在本发明的第五实施例中，电器设备300不仅可以借助滚轮130的支撑来移动，而且还能够通过驱动装置140来调整其与承载表面200之间的距离，从而能够防止电器设备300歪斜。
至此，已经结合前文的多个实施例描述了本发明的技术方案，但是，本领域技 术人员容易理解的是，本发明的保护范围并不仅限于这些具体实施例。在不偏离本发明技术原理的前提下，本领域技术人员可以对上述各个实施例中的技术方案进行拆分和组合，也可以对相关技术特征作出等同地更改或替换，凡在本发明的技术构思和/或技术原理之内所做的任何更改、等同替换、改进等都将落入本发明的保护范围之内。
