Description

自悬浮体及磁悬浮装置 技术领域
本发明涉及一种磁悬浮装置。
背景技术
现有磁悬浮装置通常包括悬浮器和悬浮体，悬浮器一般采用底座或吊架形式，悬浮体可以采用例如地球仪、蓝牙音箱、月球灯、花盆、摆件等各种合适形式。悬浮体相对于悬浮器的悬浮/落地可以通过手动或自动方式进行。CN112228734A、CN112087163A、CN110748563A、CN102315805A、CN102570927A、CN207202600U等等均公开了在悬浮器底座内设置升降机构来实现悬浮体的自动悬浮/落地。在悬浮器底座内设置升降机构必然要遭受空间和成本的双重制约。
发明内容
本发明的目的是提供一种磁悬浮装置，其能以简单方式实现悬浮体的自动悬浮或落地。
根据本发明的第一方面，提供了一种用于磁悬浮装置的悬浮体，其包括壳体以及磁性件，其中壳体与磁性件设置成是相对可运动的，并且通过悬浮体中设置的直线导向机构来引导磁性件与壳体的相对运动。
根据本发明的悬浮体，直线导向机构可以形成在壳体和/或磁性件上。
根据本发明的悬浮体，壳体优选为封闭或基本封闭壳体，更优选为球体或盒体，例如透明或不透明球体。
根据本发明的悬浮体，其中磁性件优选始终在壳体内运动。当然，磁性件也可以伸出壳体，例如向上和/或向下伸出壳体。在可以向下 伸出壳体的情况下，磁性件可以例如作为隐藏式展示架，悬浮体此时则可以用作收纳盒体。
根据本发明的悬浮体，还可以包括为磁性件与壳体的相对运动提供驱动力的电机。这种情况下，通常还可以包括将电机的驱动力传递给磁性件或壳体的传动机构。
根据本发明的悬浮体，还可以包括限位机构，用于限制磁性件与壳体的相对运动的上和/或下运动极限。
根据本发明的悬浮体，其中壳体的直线导向机构优选为直筒，磁性件位于直筒中。
在直筒导向的情况下，可以进一步优选磁性件与直筒形成活塞式抽真空机构。或者，直筒也可以形成有(上或下)限位件，压缩弹簧位于限位件和磁性件之间。因此，这时也可以省略电机来实现悬浮体的自动升降式悬浮。
当然，也可以采用其它直线导向机构例如丝杠等来与磁性件上设置的螺母配合，或者反之亦然。
根据本发明的悬浮体，壳体还可以设置有定位标记，用于指示直线运动机构的直线运动方向或磁性件的相应位置。
此外，悬浮体也可以设置有发声、发光等电器设备以及无线或有线充电设备等。
根据本发明的第二方面，还提供了一种磁悬浮装置，其包括悬浮器和上述悬浮体，其中悬浮体通过悬浮器是可悬浮的。
根据本发明的磁悬浮装置，其中悬浮器可以采用底座形式，悬浮体能够悬浮在底座上方。这种情况下，底座上表面优选设置有定位中心点，当底座水平放置时，悬浮体的磁性件能够悬浮在定位中心点的正上方。
根据本发明的磁悬浮装置，其中悬浮器也可以采用吊架形式，悬浮体能够悬浮在吊架的最高点的下方。
根据本发明的磁悬浮装置，其中悬浮器底座还可以设计为日历底座，底座设置有至少一个指示滑槽以及可移动操作地定位在所述至少 一个指示滑槽中的指示珠。所述至少一个指示滑槽可以包括两个相互径向隔开的环形指示滑槽，其中一个形成有日期标识，另一个则形成有星期或月份标识，每一个指示滑槽均对应一个相应的指示珠。另外，悬浮体可以为一半可点亮而另一半可保持相对较暗的球形月相灯。
根据本发明的第三方面，又提供了一种利用上述磁悬浮装置来升降悬浮悬浮体的方法，包括：
基本水平放置悬浮器底座；
将悬浮体置于悬浮器底座上，并使悬浮体的磁性件沿直线导向机构方向对准悬浮器底座的定位中心点；
沿直线导向机构方向将磁性件运动至设定悬浮高度以使其相对于悬浮器底座处于稳定悬浮状态；
将悬浮体的壳体相对于磁性件向上运动离开悬浮器底座，直至期望高度。
根据本发明的方法还可以包括：将悬浮体的壳体相对于磁性件向下运动直至期望高度或接触悬浮器底座。
根据本发明的方法，悬浮体的壳体与磁性件的相对运动可以通过电驱动机构执行。例如，可以在悬浮体内设置电机和传动机构来控制二者的相对运动。
根据本发明的方法，悬浮体的壳体与磁性件的相对运动也可以通过弹性自动复位机构或手动复位机构执行。这种方法省略了电机的使用，简化了装置结构并进一步降低了成本。
根据本发明的方法，弹性复位机构可以为活塞式抽真空机构和/或弹簧机构。
根据本发明的方法，还可以包括：在悬浮器底座和悬浮体上分别设置定位配合机构，以在将悬浮体放置于悬浮器底座时通过二者的定位配合机构保证悬浮体的磁性件沿直线导向机构方向对准悬浮器底座的定位中心点。
本发明通过在悬浮体内设置可直线移动或可沿竖向移动的磁性件，从而实现了无需在悬浮器底座内设置升降机构即可简单实现悬浮 体相对于悬浮器底座的自升降式悬浮或落地。这不但具有极其强烈的视觉特效和神奇感，还使得悬浮器底座仍然可保持原有紧凑或小型化的扁平结构。

图1示出了根据本发明第一实施例的悬浮体LO的剖面结构示意图。悬浮体LO包括球形壳体10，壳体底部任选设置有定位凹口11。壳体10内部固定设置有竖向导向筒12。导向筒12的中心对称轴与定位凹口11竖向对齐。导向筒12的上部和下部还任选设有通气孔13和14。
圆柱形磁性件20设置于导向筒12内，并任选通过位于其外圆周壁上的密封环21与导向筒12的内壁形成紧密配合关系。压缩弹簧15任选设置在磁性件20与导向筒12的顶盖15之间。
图2以剖视图方式示出了悬浮体LO放置在作为悬浮器的底座LB上时的示意图。如图所示，底座LB的上表面任选设置有定位突起P，其插入悬浮体LO的定位凹口11，从而起到初始定位作用。
如图2所示，当悬浮体LO放置在底座LB上时，由于底座LB中的磁组件例如环形磁铁(未示出)对悬浮体LO中的磁性件20所产生的斥力作用，磁性件20从图1所示的导向筒12的底部自动上升至图2所示的设定悬浮高度(该设定悬浮高度由取决于装置本身的具体设置)并稳定悬浮在该平衡位置。这时，例如在取消下部通气孔14，甚至还包括取消导向筒12的顶盖15以及弹簧15的情况下，由于带有密封环21的磁性件20作为活塞的抽真空作用，导向筒12中位于磁性件20下方的空间形成近似真空状态。接下来，悬浮体LO的壳体10由于真空作用会自动上升，直至导向筒12的底部基本接触磁性件20，如图3所示。另外，由于真空阻尼作用，悬浮体LO会自底座LB冉冉升起，从而极具视觉特效。
图2中，也可以同时保留顶盖15、弹簧16、上部和下部通气孔 13和14，并任选保留密封环21，这时由于弹簧16对顶盖15施加的压力作用，悬浮体LO的壳体10仍然会自动上升至如图3所示位置。
当然，本领域技术人员可以理解，作为壳体10与磁性件20的相对复位机构，上述活塞抽真空作用和弹簧压力作用也可以同时组合使用。另外，也可以使用其它合适的弹性复位机构。此外，复位机构也可以不采用弹性自动复位机构而手动进行，例如在作为直线导向机构的导向筒上和磁性件20上分别设置弹性卡接对配机构，通过施加外力(例如向下按压壳体10)实现二者的接合和脱离。此外，还可以使用不同于导向筒形式的其它合适的直线导向机构例如导杆等。
图4示出了根据本发明第二实施例的悬浮体LO的剖面结构示意图。悬浮体LO包括球形壳体10，壳体底部任选设置有定位凹口11。壳体10内部固定设置有筒状支架17，支架17上固定安装有带有中空螺纹旋转轴的电机18。电机18通过外壳固定在支架17上，其中空螺纹旋转轴沿竖向布置，与定位凹口11沿竖向对齐。
圆柱形磁性件20’上设置在支架17内部，其上固定安装有螺纹柱22。螺纹柱22向上伸出支架17并以螺纹配合方式穿过电机18的中空螺纹旋转轴。
图5以剖视图方式示出了悬浮体LO放置在作为悬浮器的底座LB上时的示意图。如图所示，底座LB的上表面任选设置有定位突起P，其插入悬浮体LO的定位凹口11，从而起到初始定位作用。
如图6所示，当悬浮体LO放置在底座LB上时，通过初始设定或电机18的驱动使磁性件20’位于设定悬浮高度，这时由于底座LB中的磁组件例如环形磁铁(未示出)对悬浮体LO中的磁性件20’所产生的斥力作用，磁性件20’将稳定悬浮在该平衡位置。接下来，例如通过底座LB上设置的远程开关(未示出)或遥控器驱动电机18的中空螺纹旋转轴转动，从而使电机18带动悬浮体LO的壳体10沿磁性件20’上的螺纹柱22向上旋转式上升并离开底座LB，直至壳体10的底部接近磁性件20’，如图6所示。此后，可以控制电机18翻转来使壳体10下降至期望高度或图5所示的初始落地位置。另外，由于壳体10的旋转式升降运动，悬浮体LO从底座升起时即可沿水平 方向旋转，从而别具视觉特效。
图7为根据本发明第二实施例的悬浮体的一个变型的示意图，其中的传动装置不同于图4所示实施例，其它不变。
如图7所示，固定在支架17上的电机18’为普通电机，具有竖向向下伸出的旋转轴19’。电机18’的外壳仍然固定在支架17上，但与磁性件20’的螺纹柱22平行错开。旋转轴19’与齿轮101固定在一起，齿轮101与传动齿轮102啮合，传动齿轮102又与自其穿过的磁性件20’的螺纹柱22形成螺纹配合连接。这种情况下，电机18’同样可以驱动悬浮体LO的壳体10自动升降，如图8所示。
图9为根据本发明第二实施例的悬浮体的一个变型的示意图，其中的传动装置不同于图4和图7所示实施例，其它不变。
如图9所示，筒状支架17上套设有可沿其上下滑动的外筒103，外筒103上还设置有引导肋104以使外筒103相对于筒状支架17只能上下移动而不可相对转动。固定在外筒103上的电机18’也为普通电机，具有竖向向下伸出的旋转轴19’。旋转轴19’与磁性件20’的螺纹柱22沿竖向对齐并固定在一起。螺母105在固定在筒状支架17顶部，与自其穿过的磁性件20’的螺纹柱22形成螺纹配合连接。这种情况下，电机18’同样可以驱动悬浮体LO的壳体10自动升降，如图10所示。
图11示出了构造为日历底座形式的底座LB。所示圆盘形底座LB具有外壳30，外壳30形成有中央圆形接收凹区33，两个同心环形槽形式的第一指示滑槽31和第二指示滑槽32围绕接收凹区33相互径向隔开地设置在外壳30的上表面。第一指示珠311可移动操作地定位在第一指示滑槽311中的多个设定位置310之一，第二指示珠321可移动操作地定位在第二指示滑槽32中的多个设定位置320之一。所示第一指示珠311和第二指示珠321可以为铁球，由于如后所述外壳30中还包括位于第一指示滑槽31和第二指示滑槽32下面的环形磁铁35，因此沿指示滑槽移动或拨动相应的铁球时能够将其快速便捷地定位在指示滑槽的所需设定位置。
在图11所示日历底座中，除了接收凹区以及环形槽所在区域之外，所示底座LB的圆盘本体的高度沿径向向外逐渐减小。
图12所示实施例与图2所示类似，不同之处在于采用了图11所示日历底座LB。如图12所示，底座LB的外壳30内还设置有磁悬浮系统，磁悬浮系统包含控制电路板34、环形磁铁35、电磁线圈26、以及铁芯37等。悬浮体LO同样可以如上所述从图12所示位置上升至图13所示位置。
图14为悬浮体LO悬浮在图11所示日历底座LB上方的透视图，其中悬浮体LO采用了球形月相灯形式。这种球形月相灯能够在其球形外表面上形成亮度不一致区域例如图示一半黑暗区和一半点亮区。这种球形月相灯可以具有一半透明且另一半不透明或半透明的球形外壳及位于球形外壳内部的光源。
可替代地，这种球形月相灯可以具有3D打印形成的球形外壳和光源，球形月相灯内部由隔光板分为两部分，光源则位于其中一部分内。进一步地，球形月相灯内部由隔光板隔开的两部分可以均具有可独立受控的光源以根据需要实现半亮或全亮状态。
图15所示实施例类似于图14所示，不同之处在于采用了总体呈扁平形状的日历底座。
图16为图15所示日历底座的俯视图，其中所示弧形指示滑槽31的设定位置处还设置有相应的星期标识，弧形指示滑槽32的设定位置处还设置有相应的日期标识。图17为图16所示日历底座LB的正视图，其上还设置有充电口38。在图17所示实施例中，虽然没有具体示出，底座LB内还设置有无线充电发射装置，球形月相灯内还设置有与底座的无线充电发射装置对应的无线充电接收装置以为球形月相灯进行无线供电或充电。这种磁悬浮日历装置可以逼真地模拟月相变化，并且日历指示醒目清楚。
本领域技术人员可以理解，在采用电机的情况下，还可以有其它传动装置的变型。直线导向机构也不局限于上述螺纹或螺母形式，例如也可以采用气动驱动方式所使用的气缸来作为直线导向机构。
另外，虽然没有具体示出，悬浮体也可以设置有声音或灯光等电器设备。此外，悬浮体还可以设置无线或有线充电设备等来为其中的耗电设备供电。例如，在采用无线供电的情况下，悬浮体内可以设置无线供电接收线圈来与底座内设置的无线供电发射线圈相配合。
此外，虽然没有具体示出，本发明的悬浮体还可以包括限位机构，用于限制磁性件与壳体的相对运动的上和/或下运动极限。例如，可以为电机设置行程开关，使其在预定位置自动停止工作。
本领域技术人员应当理解，以上图示实施例仅用于更好地理解本发明而非用于任何限制目的。例如，上述方向术语仅针对附图而言。另外，本发明的悬浮体LO的壳体10也不局限于这种封闭球壳结构，还可以使用其它形状例如方形盒体或任何其它合适的封闭或半封闭或开放式造型。此外，壳体10可以由透明、不透明或不透明材料制成。此外，本发明的磁性件20或20’也不局限于总是位于壳体10中，其也可以在运动过程中向上或向下露出壳体10。
