本申请提出一种智能语音磁悬浮台灯。
在本申请一实施例中，参照图1至图9，该智能语音磁悬浮台灯1包括底座10、连接杆组20、灯座30、灯头40以及无线供电装置，连接杆组20的下端与底座10连接，连接杆组20的上端与灯座30相连，灯座30内设有磁性悬浮模块310，灯头40的顶端设有磁性悬浮件420，磁性悬浮件420与磁性悬浮模块310产生磁力，磁力与灯头40的重力相平衡，以将灯头40悬浮于灯座30的下方；无线供电装置包括发射线圈320和接收线圈450，发射线圈320设有灯座30内，接收线圈450设于灯头40内，灯头40内还设有与接收线圈450电性连接的发光灯芯410；底座10包括：底壳110；供电模块120，设于底壳110内，供电模块120与发射线圈320电性连接；以及语音控制装置130，设于底壳110内，语音控制装置130与供电模块120电性连接，语音控制装置130用以根据用户语音控制供电模块120向发射线圈320供电。
具体的，灯座30通过连接杆组20与底座10相连接，连接杆组20具有一定的自由度，从而可以通过调整连接杆组20，实现对灯座30位置的调整。底座10内部可以内置有电池，电池与供电模块120相连接，从而实现供电模块120的供电功能。当然，该电池也可以具有充电功能，在底壳110上设置有充电接口，从而便于对电池进行充电，以保障电池对供电模块120的持续供电。
供电模块120除了可以通过电池供电外，也可以采用外接电源的方式进行供电，底壳110上设置有供电接口，供电接口与供电模块120电性连接，进而通过外部的电源对供电模块120进行供电。供电模块120与发射线圈320采用导线连接，导线可以隐藏设置于连接杆组20的内部，或者导线沿连接杆组20的表面进行走线固定。灯头40的顶端设置有与发射线圈320能够无线配合的接收线圈450，灯座30采用无线供电方式对灯头40进行供电，进而使灯头40无需与灯座30接触，也能实现灯头40内发光灯芯410通电发光。
灯座30内设置有磁性悬浮模块310，灯头40的顶端设置有磁性悬浮件420，磁性悬浮件420受到磁性悬浮模块310的磁力作用，且该磁力与灯头40 自身的重力相平衡，从而将灯头40悬浮于灯座30的下方。由于灯头40与灯座30采用无线供电的方式，进而悬浮于灯座30下方的灯头40也可以实现通电发光效果。
本智能语音磁悬浮台灯1还具有语音声控功能，该底座10包括语音控制装置130，语音控制装置130与供电模块120相连接，语音控制装置130可以拾取用户的语音命令，进而控制供电模块120是否向发射线圈320供电，从而得以声控灯头40的发光装置。
需要说明的是，上述语音控制装置130可以基于本地语音控制方式或者互联网语音控制方式实现对供电模块120的控制。下面对本地语音控制方式和互联网语音控制方式的原理做以阐述：
在本地语音控制方式中，上述语音控制装置130预先录制并储存用户的语音命令，当用户在说出对应的语音命令时，语音控制装置130则发出响应信号来对供电模块120进行控制。在互联网语音控制方式中，语音控制装置130直接拾取用户当前的语音命令，并将该语音命令通过互联网数据库进行语境、语意的解析对比，进而获取用户的控制指令，然后再根据该控制指令对供电模块120进行控制。本申请技术方案通过采用将灯头40采用磁悬浮方式悬浮于灯座30下方，同时灯座30对灯头40采用无线供电方式进行供电，从而使悬浮于灯座30下的灯头40可以正常发光，使得产品富有科技炫酷感，有助于改善产品的装饰观赏效果；底座10上设置有语音控制装置130，可以控制供电模块120向发射线圈320供电，使得用户通过语音来控制灯头40的发光状态，也大幅度改善用户使用体验。
进一步地，继续参照图9，上述语音控制装置130包括麦克风132和与麦克风132电性连接的语音控制PCB板131，语音控制PCB板131与供电模块120电性连接，底壳110上对应麦克风132的位置开设有拾音孔111。其中，该语音控制PCB板131可以采用上述本地语音控制方式或者互联网语音控制方式实现对供电模块120的控制。其中，麦克风132可用于采集拾取用户的语音信息，底壳110上开设有拾音孔111，进而便于用户声音传入麦克风132中。上述拾音孔111优选设有多个，且多个拾音孔111对应麦克风132呈环形排布，进而改善麦克风132的拾音效果。
当然，对于灯头40的控制除了可以通过语音控制装置130进行声控之外， 还可以增加传统的开关控制。具体的，在本实施例中，上述底座10还设有第一开关112，第一开关112与供电模块120电性连接，第一开关112用于控制供电模块120向发射线圈320供电。该第一开关112可以是触摸式、按钮式、旋钮式、拨动式等类型的开关，此处不作具体限定。通过设置第一开关112，可以在用户不便于语音控制或者语音控制出现故障的场景下，还能实现对灯头40通电发光的控制。
进一步地，参照图3，并结合10至图13，上述磁性悬浮件420包括永磁体，上述磁性悬浮模块310包括铁芯311、电磁线圈312、霍尔传感器313以及悬浮控制单元；铁芯311沿竖向设于灯座30内；电磁线圈312绕制于铁芯311的外周面，且电磁线圈312的供电端与供电模块120相连；霍尔传感器313设于铁芯311的下端面，用以检测磁性悬浮件420与铁芯311之间的距离；悬浮控制单元分别与霍尔传感器313、供电模块120相电性连接；当磁性悬浮件420与铁芯311之间的距离为预设范围时，霍尔传感器313向悬浮控制单元反馈一位置信号，悬浮控制单元根据位置信号控制供电模块120向电磁线圈312供电，电磁线圈312通电产生排斥永磁体的电磁斥力，电磁斥力和灯头40的重力之和，与永磁体和铁芯311之间的磁吸力相平衡，以使灯头40悬浮于灯座30之下。
可以理解的是，对于上述磁性悬浮模块310而言，铁芯311和电磁线圈312形成一电磁铁结构，而永磁铁本身具有磁性，无论电磁线圈312是否通电，永磁铁均可直接与铁芯311产生相互吸引的磁吸力，且该磁吸力大于灯头40的自身重力。如此一来，在电磁线圈312没有没有通电或者突然断电时，通过永磁铁与铁芯311之间的磁吸力，可以保证灯头40会牢靠地吸附于灯座30的底面处，避免灯头40掉落，使得灯头40具有防跌落的功能。
为了实现灯头40能够悬浮于灯座30之下，灯座30内设置有检测永磁铁位置的霍尔传感器313，当灯头40位于预设位置时，此时永磁铁与铁芯311之间的距离处于预设范围内，霍尔传感器313向悬浮控制单元反馈一位置信号，悬浮控制单元根据位置信号控制供电模块120向电磁线圈312供电，电磁线圈312与铁芯311形成磁性与永磁体的磁性相同的电磁铁，电磁铁与永磁体之间产生电磁斥力，进而灯头40受到灯座30向下的排斥作用，而当电磁斥力、灯头40的自身重力与上述磁吸力达到平衡时，即可将灯头40悬浮 于灯座30下方的预设位置处。而一旦电磁线圈312断电，则电磁铁产生的电磁斥力消失，由于磁吸力大于灯头40自身的重力，灯头40则会从悬浮状态向上运动，直接被吸附于灯座30底面处。通过设置上述磁吸悬浮模块和磁性悬浮件420，可以实现当智能语音磁悬浮台灯1不通电工作或者突然断电时，灯头40能够自动吸附于灯座30底面处，实现了灯头40的防跌落保护功能。
在本实施例中，也可以通过语音控制装置130实现将灯头40从悬浮状态切换至吸附状态。其中，语音控制装置130还用于控制供电模块120向电磁线圈312供电，且当电磁线圈312断电时，永磁体与铁芯311相互吸附，进而使得灯头40磁性吸附于灯座30的底面处。如此一来，用户可以主动操控灯头40从悬浮状态切换到吸附状态，进而扩展了用户语音控制的功能和场景，使本智能语音磁悬浮台灯1具有更多的可操控性。
值得说明的是，受现有的无线供电技术的限制，发射线圈320和接收线圈450进行电能传递的效率较低，存在供电功率小的缺陷，进而当灯座30对灯头40进行无线供电时，发光灯芯410由于供电功率较小而亮度较低。
进一步地，为了克服灯头40发光亮度低的问题，在本实施例中，上述灯座30的底面还设有与供电模块120电性连接的第一供电触点330；灯头40的顶部设有第二供电触点430，第二供电触点430与发光灯芯410电性连接；当灯头40磁性吸附于灯座30的底面处时，第一供电触点330与第二供电触点430相互抵接，以使供电模块120与发光灯芯410电性连接。当用户需要增强灯头40的亮度时，可以通过语音控制装置130或者第一开关112将灯头40由悬浮状态切换至吸附装置，此时除了发光灯芯410除了通过发射线圈320与接收线圈450之间的无线供电之外，还有第一供电触点330和第二供电触点430之间采用有线传导的方式进行供电，此时发光灯芯410的供电功率增大，则发光灯芯410的亮度也会提高。
由于有线传导的供电方式的供电功率明显可以大于无线供电的供电功率，因此，通过设置上述第一供电触点330和第二供电触点430，可以使得本智能语音磁悬浮台灯1的灯头40具有两种亮度、且亮度差异较大的发光模式，进而可以满足用户的多种使用需求。例如，当用户在看书时，需要灯头40产生较高的亮度，此时灯头40通过第一供电触点330和第二供电触点430接触供电、以及发射线圈320和接收线圈450的无线供电方式相结合的方式进行 供电，此时发光灯芯410的发亮亮度较高；当用户需要夜灯功能时，此时对灯头40的亮度要求降低，进而在灯头40处于悬浮状态时，灯头40仅通过发射线圈320和接收线圈450进行无线供电即可满足要求。
需要说明的是，在一些其他实施方案中，当灯头40吸附于灯座30的底面处时，供电模块120也可停止对发射线圈320进行供电，即供电模块120仅向第一供电触点330供电，灯头40仅通过第一供电触点330和第二供电触点430相互接触的有线供电方式来通电工作。
进一步地，灯座30的底面设有第一定位件340，灯头40的顶部设有第二定位件440，当灯头40磁性吸附于灯座30的底面处时，第一定位件340和第一定位件340相互配合。如此一来，可以保障在灯头40与灯座30吸附接触时，第一供电触点330和第二供电触点430能够可靠地抵接，避免了第一供电触点330和第二供电触点430发生偏移错位而导致灯头40无法供电的缺陷。
作为优选方式的是，上述第一定位件340朝下呈凸面状设置，第二定位件440朝上呈凹面状设置；或者，上述第一定位件340朝下呈凹面状设置，第二定位件440朝上呈凸面状设置。如此一来，第一定位件340和第二定位件440通过凹凸的曲面进行配合，第一定位件340和第二定位件440会沿曲面轮廓滑动至配合位置，进而更利于灯头40能相对稳定、且定位吸附于灯座30的底面处。在一些具体的实施过程中，上述第一定位件340的结构可以与第一供电触点330相结合，上述第二定位件440的结构可以与第二供电触点430相结合，进而可以减少额外设置第一定位件340和第二定位件440，从而到达简化灯头40、灯座30的结构，降低了产品的生产成本。
进一步地，除了可以通过语音控制装置130对上述电磁线圈312是否通电进行语音控制外，还可以增加传统的开关控制。具体的，在本实施例中，上述底座10还设有第二开关113，第二开关113与供电模块120电性连接，第二开关113用于控制供电模块120向电磁线圈312供电，且当电磁线圈312断电时，永磁体与铁芯311相互吸附，以使灯头40磁性吸附于灯座30的底面处。该第二开关113可以是触摸式、按钮式、旋钮式、拨动式等类型的开关，此处不作具体限定。通过设置第二开关113，可以在用户不便于语音控制或者语音控制出现故障的场景下，还能实现对电磁线圈312的通电控制。如此一来，通过第二开关113，也可以实现将灯头40从悬浮状态切换为吸附状 态。
本申请提出一种磁悬浮无线充电台灯，为上面实施例中所提出的智能语音磁悬浮台灯中的一种。
在本申请一实施例中，参照图14至图17，并结合图18和图19，该磁悬浮无线充电台灯1包括底座10、连接杆20、灯座30以及灯头40，连接杆20的下端与底座10连接，连接杆20的上端与灯座30相连，灯座30内设有磁性悬浮模块310，灯头40的顶端设有磁性悬浮件410，磁性悬浮件410与磁性悬浮模块310产生磁力，磁力与灯头40的重力相平衡，以将灯头40悬浮于灯座30的下方；灯座30内设有第一发射线圈320，灯头40内具有第一接收线圈420以及与第一接收线圈420电性连接的发光灯芯；底座10包括：底壳110；供电模块120，设于底壳110内，供电模块120通过内置于连接杆20内的导线与第一发射线圈320电性连接；无线充电模块130，设于底壳110内，无线充电模块130包括无线充电PCB板131以及与无线充电PCB板131电性连接的第二发射线圈132，第二发射线圈132临近底壳110的上侧面设置。
具体的，灯座30通过连接杆20与底座10相连接，连接杆20具有一定的自由度，从而可以通过调整连接杆20，实现对灯座30位置的调整。底座10内部可以内置有电池，电池与供电模块120相连接，从而实现供电模块120的供电功能。当然，该电池也可以具有充电功能，在底壳110上设置有供电接口，从而便于对电池进行充电，以保障电池对供电模块120的持续供电。可以理解的是，供电模块120除了可以通过电池供电外，也可以采用外接电源的方式进行供电，底壳110上设置有供电接口，供电接口与供电模块120电性连接，进而通过外部的电源对供电模块120进行供电。供电模块120与第一发射线圈320采用导线连接，导线可以隐藏设置于连接杆20的内部，或者导线沿连接杆20的表面进行走线固定。灯头40的顶端设置有与第一发射线圈320能够无线配合的第一接收线圈420，灯座30采用无线供电方式对灯头40进行供电，进而使灯头40无需与灯座30接触，也能实现灯头40内发光灯芯通电发光。灯座30内设置有磁性悬浮模块310，灯头40的顶端设置有磁性悬浮件410，磁性悬浮件410受到磁性悬浮模块310的磁力作用，且该磁力与灯头40自身的重力相平衡，从而将灯头40悬浮于灯座30的下方。由于灯头40与灯座30采用无线供电的方式，进而悬浮于灯座30下方的灯头40 可以实现通电发光效果。如此，悬浮的发光灯头40，富有科技美感，引人注目，进而可以产生较佳的装饰观赏效果。
同时，对于本磁悬浮无线充电台灯1而言，其还具备有无线充电功能，可以对目前流行的具有无线充电功能的手机、智能手表等设备进行无线充电。当然，对于一些常规不具备无线充电功能的手机，也可通过安装无线充电接收器(线圈贴片)的方式，实现对常规手机的无线充电。其中，本磁悬浮无线充电台灯1的无线充电功能主要通过内置于底座10底壳110内的无线充电模块130来实现，无线充电模块130包括无线充电PCB板131、第二发射线圈132，无线充电PCB板131与底壳110内的供电模块120电性连接，无线充电PCB板131具有无线充电电路，该无线充电电路的输入端与供电模块120相连接，该无线充电电路的输出端与第二发射线圈132相连接，第二发射线圈132临近底壳110的上侧面设置，进而以便更好地贴近待充电设备(例如具有无线充电功能的手机、智能手机等)。如此一来，用户将待充电设备放置于底座10上表面时，第二发射线圈132通电工作，进而可以对待充电设备进行无线充电。
本申请技术方案通过采用将灯头40采用磁悬浮方式悬浮于灯座30下方，同时灯座30对灯头40采用无线供电方式进行供电，从而使悬浮于灯座30下的灯头40可以正常发光，使得产品富有科技炫酷感，有助于改善产品的装饰观赏效果；底座10内置有无线充电模块130来实现，无线充电模块130的第二发射线圈132可以向待充电设备(例如具有无线充电功能的手机、智能手机等)进行无线充电，扩展了台灯的无线充电功能，可满足用户的多重使用需求。
进一步地，对于上述底座10而言，该底座10还包括固定于底壳110内的配重块140，供电模块120与无线充电模块130分别安装固定于配重块140。设置配重块140，一方面可增大底座10的重量，避免磁悬浮无线充电台灯1因重心不稳而发生倾斜翻到现象；另一方面，配重块140提供了一个安装支架结构，可便于将供电模块120与无线充电模块130等安装固定在底壳110内，进而简化底壳110的结构。在本实施例中，上述配重块140的上侧面设有供容置无线充电PCB板131的容置槽141，无线充电PCB板131可拆卸地固定于容置槽141内，第二发射线圈132位于无线充电PCB板131背对容置 槽141槽底的一侧。其中无线充电PCB板131通过螺钉锁附固定于容置槽141的槽底，或者无线充电PCB板131采用卡扣固定于容置槽141内。当然，于一些其他实施例中，该无线充电PCB板131也可采用胶粘方式直接固定于容置槽141内。为了保障待充电设备的充电效果，对于本磁悬浮无线充电台灯1而言，其底壳110包括外壳罩111和底板112，外壳罩111上侧的外壁面对应第二发射线圈132的位置优选设置有待充电设备放置标示113。如此一来，通过设置待充电设备放置标示113，进而可引导用户将待充电设备放置在充电最佳位置，进而使无线充电的效果达到最佳。
进一步地，参照图20至图22，上述底座10还设置有无线充电指示灯150，无线充电指示灯150与无线充电PCB板131相连接，无线充电指示灯150具有至少两种发光色，以使无线充电指示灯150在无线充电模块130的工作状态和待机状态的指示颜色不同。例如，该无线充电指示灯150具有红色和绿色两种发光颜色，当底座10上未放置待充电设备时，无线充电模块130未工作，此时无线充电指示灯150显示为红色；当待充电设备放置于底座10上时，无线充电模块130开始进行无线充电，此时无线充电指示灯150显示为绿色。
此外，为了进一步扩展本磁悬浮无线充电台灯1的实用性，其底座10还设有用以向待充电设备供电的电源输出接口170，且该电源输出接口170为USB接口或Type-C接口。如此，也可通过连接线对待充电设备进行有线充电或者供电，进而满足用户更多的充电需求。其中，作为优选方案的是，上述电源输出接口170的数量具有多个，且至少其中一个的电源输出接口170为USB接口。
参照图14和图15，并结合图16和图17，对于本磁悬浮无线充电台灯1，其磁性悬浮件410包括永磁体，上述磁性悬浮模块310包括铁芯311、电磁线圈312、霍尔传感器313以及悬浮控制单元314；铁芯311沿竖向设于灯座30内；电磁线圈312绕制于铁芯311的外周面，且电磁线圈312的供电端与供电模块120相连；霍尔传感器313设于铁芯311的下端面，用以检测磁性悬浮件410与铁芯311之间的距离；悬浮控制单元314分别与霍尔传感器313、供电模块120相电性连接；当磁性悬浮件410与铁芯311之间的距离为预设范围时，霍尔传感器313向悬浮控制单元314反馈一位置信号，悬浮控制单元314根据位置信号控制供电模块120向电磁线圈312供电，电磁线圈312 通电产生排斥永磁体的电磁斥力，电磁斥力和灯头40的重力之和，与永磁体和铁芯311之间的磁吸力相平衡，以使灯头40悬浮于灯座30之下。
可以理解的是，对于上述磁性悬浮模块310而言，铁芯311和电磁线圈312形成一电磁铁结构，而永磁铁本身具有磁性，无论电磁线圈312是否通电，永磁铁均可直接与铁芯311产生相互吸引的磁吸力，且该磁吸力大于灯头40的自身重力。如此一来，在电磁线圈312没有通电或者突然断电时，通过永磁铁与铁芯311之间的磁吸力，可以保证灯头40会牢靠地吸附于灯座30的底面处，避免灯头40掉落，使得灯头40具有防跌落的功能。
为了实现灯头40能够悬浮于灯座30之下，灯座30设置有检测永磁铁位置的霍尔传感器313，当灯头40位于预设位置时，此时永磁铁与铁芯311之间的距离处于预设范围内，霍尔传感器313向悬浮控制单元314反馈一位置信号，悬浮控制单元314根据位置信号控制供电模块120向电磁线圈312供电，电磁线圈312与铁芯311形成磁性与永磁体的磁性相同的电磁铁，电磁铁与永磁体之间产生电磁斥力，进而灯头40受到灯座30向下的排斥作用，而当电磁斥力、灯头40的自身重力与上述磁吸力达到平衡时，即可将灯头40悬浮于灯座30下方的预设位置处。而一旦电磁线圈312断电，则电磁铁产生的电磁斥力消失，由于磁吸力大于灯头40自身的重力，灯头40则会从悬浮状态向上运动，直接被吸附于灯座30底面处。通过设置上述磁性悬浮模块310和磁性悬浮件410，可以实现当磁悬浮无线充电台灯1不通电工作或者突然断电时，灯头40能够自动吸附于灯座30底面处，实现了灯头40的防跌落保护功能。
上述底座10还设有第二开关180，第二开关180与供电模块120电性连接，第二开关180用于控制供电模块120向电磁线圈312供电，且当电磁线圈312断电时，永磁体与铁芯311相互吸附，以使灯头40磁性吸附于灯座30的底面处。该第二开关180可以是触摸式、按钮式、旋钮式、拨动式等类型的开关，此处不作具体限定。通过设置第二开关180，实现对电磁线圈312的通电控制，也将灯头40从悬浮状态切换为吸附状态。
以上仅为本申请的优选实施例，并非因此限制本申请的专利范围，凡是在本申请的发明构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
