具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象,而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换,以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施,且“第一”、“第二”等所区分的对象通常为一类,并不限定对象的个数,例如第一对象可以是一个,也可以是多个。此外,说明书以及权利要求中“和/或”表示所连接对象的至少其中之一,字符“/”,一般表示前后关联对象是一种“或”的关系。
下面结合附图,通过具体的实施例及其应用场景对本申请实施例提供的无线充电器进行详细地说明。
请参阅图1,本申请实施例提供的无线充电器包括:基板12、上盖板11、压敏组件3和磁吸件4。
基板12与上盖板11沿第一方向(如图3中的方向X)层叠设置,且上盖板11能够相对基板12沿所述第一方向移动,压敏组件3设于基板12的面向上盖板11的一侧;
压敏组件3与磁吸件4电连接,压敏组件3用于检测上盖板11压设于基板12上的压力值,无线充电器根据所述压力值调节磁吸件4的磁吸方向和磁吸力度中的至少一项。
在实施中,如图1所示,基板12和上盖板11可以扣合在一起,形成壳体1,且压敏组件3和磁吸件4等其他结构可以收容在壳体1内的收容腔内,且基板12和上盖板11能够沿第一方向X进行相对的移动,例如:当本申请实施例提供的无线充电器在给待充电设备充电的过程中,该待充电设备承载 在上盖板11上,从而在该待充电设备的重力作用下,将上盖板11压向基板12,此时压敏组件3所检测到的压力值大于上盖板11未承载待充电设备时的压力值。当本申请实施例提供的无线充电器未给待充电设备充电的过程中,或者用户将待充电设备拿起的过程中,上盖板11可以离开基板12。
其中,压敏组件3可以包括压力检测装置,用于检测上盖板11所承受的压力值,或者,压敏组件3可以包括压敏电阻,例如:该压敏电阻所受到的压力越大,则其电流值越小,这样,通过压敏组件3输出的电流值的大小,便可以确定对应的压力值,在此对压敏组件3的具体类型不作具体限定。
此外,上述磁吸件4可以是任意磁场方向和/或磁场强度可调的结构,例如:磁吸件4包括电磁体,通过调节该电磁体流过的电流大小,便可以调节磁吸件4产生的磁场强度,和/或,通过调节该电磁体流过的电流的方向,便可以调节磁吸件4产生的磁场方向。
在一种可选的实施方式中,可以将压敏组件3设置为所受压力越大,则输出电流越大的压敏电阻,且磁吸件4包括电磁体,这样,通过将该压敏电阻的输出电流输入至电磁体,便可以实现根据上盖板11所承受的压力来调节磁吸件4的磁场强度,以实现上盖板11所承受的压力越小,则磁吸件4所产生的磁吸力也越小,例如:用户拿起吸附在上盖板11上的待充电设备时,磁吸件4所产生的磁吸力减小,从而使待充电设备与无线充电器分离。
当然,在实施中,还可以在无线充电器中设置控制模块2,该控制模块2与压敏组件3和磁吸件4分别连接,这样,控制模块2能够根据压敏组件3的输出信号来判断无线充电器是否处于目标状态,从而据此调节磁吸件4所产生的磁吸力。其中,目标状态可以是:用户将待充电设备从无线充电器上取下的状态,此时,压敏组件3可以通过检测上盖板11所承受的压力值、检测上盖板11上有没有承载待充电设备等方式,以使控制模块2能够在上盖板11所承受的压力值小于或者等于第一预设值时,确定所述无线充电器处于目标状态,或者,控制模块2能够在获取到N次用于表示上盖板11所承受的压力值大于或者等于第一预设值的状态信息,且N为大于0的偶数时,确定所 述无线充电器处于目标状态,或者,控制模块2能够在获取到表示上盖板11上没有承载待充电设备时,确定所述无线充电器处于目标状态。
与之相对应的,控制模块2能够在上盖板11所承受的压力值大于或者等于第一预设值时,确定所述无线充电器处于非目标状态(例如:无线充电器正常给待充电设备充电的状态),或者,控制模块2能够在获取到M次用于表示上盖板11所承受的压力值大于或者等于第一预设值的状态信息,且M为大于0的奇数时,确定所述无线充电器处于非目标状态,或者,控制模块2能够在获取到表示上盖板11上有承载待充电设备时,确定所述无线充电器处于非目标状态。其中,非目标状态可以是无线充电器对上盖板11上承载的待充电设备进行无线充电的状态。
其中,压敏组件3输出的状态信息可以是数字信号,也可以是模拟信号,控制模块2可以是任意能够根据接收信号产生对应的输出信号的装置、逻辑单元、控制电路、开关电路、控制芯片等,在此不作具体限定。例如:假设压敏组件3在检测到上盖板11上承载有待充电设备时,可以输出第一取值的电信号,压敏组件3在检测到上盖板11上未承载有待充电设备时,可以输出第二取值的电信号,这样,控制模块2能够在从压敏组件3接收到第二取值的电信号时,确定上盖板11上未承载有待充电设备,从而确定无线充电器处于目标状态。
在一种可能的实现方式中,压敏组件3为压力检测装置,用于检测上盖板11受到的压力,其中,在正常充电状态下,上盖板11承载整个待充电设备的重量,因此,会受到的压力较大;在用户需要取下待充电设备时,用户将待充电设备抬起,上盖板11此时的重量明显小于整个待充电设备的重量,因此,会受到的压力较小。基于此,在压敏组件3检测到上盖板11接收到的压力小于或者等于第一预设压力值(可以根据与本申请实施例提供的无线充电器适配的待充电设备的重量设置,或者将第一预设压力值设为0)时,控制模块2可以确定无线充电器处于目标状态,进而可以控制无线充电器退出充电模式。与之相对应的,在压敏组件3检测到上盖板11接收到的压力大于 或者等于第一预设压力值(可以根据与本申请实施例提供的无线充电器适配的待充电设备的重量设置,或者将第一预设压力值设为0)时,控制模块2可以确定无线充电器处于非目标状态,进而可以控制无线充电器进入充电模式。
在一种可能的实现方式中,压敏组件3为压力检测装置,用于检测上盖板11受到的压力,其中,在压敏组件3检测到上盖板11接收到的压力大于或者等于第二预设压力值(可以是0或者略大于0的压力值)时,可以是用户按压上盖板11,控制模块2可以在用户按压上盖板11的次数为奇数时,开启磁吸件4,以进入充电模式。与之相对应的,控制模块2可以在用户按压上盖板11的次数为偶数时,关闭磁吸件4,以退出充电模式。
需要说明的是,本申请实施例中,控制模块2控制无线充电器进入充电模式,可以是控制磁吸件4将待充电设备吸附在上盖板11上,并控制无线充电器内的充电模块5开始向待充电设备充电;与之相对应的,控制模块2控制无线充电器退出充电模式,可以是控制磁吸件4关闭,以使用户能够轻易地取下上盖板11上的待充电设备,并控制无线充电器内的充电模块5停止向待充电设备充电。
可选的,控制模块2还用于在根据所述状态信息确定所述无线充电器处于非目标状态的情况下,控制磁吸件4产生与所述非目标状态对应的磁力。
在实施中,上述与所述非目标状态对应的磁力可以是能够维持将待充电设备吸附在上盖板11上所需的最小的磁力,这样,可以减少磁吸件4的能耗。
可选的,磁吸件4可以是磁力大小和/或方向可控的任一装置,例如:如图2所示实施例中,磁吸件4包括:导磁体41和绕设于导磁体41周沿的第一线圈42,导磁体41的径向与所述第一方向同向。
在实施中,在所述压力值增大的情况下,第一线圈42的电流增大和/或第一线圈42的电流朝向第二方向,其中,在第一线圈42通过所述第二方向的电流时,导磁体41产生第三方向的磁吸力,第三方向由上盖板11朝向基板12。
在应用中,当待充电设备放置在本申请实施例提供的无线充电器的上盖板11上时,若导磁体41产生第三方向的磁吸力,则通过该磁吸力能够将待充电设备吸附在无线充电器的上盖板11上,从而实现磁吸对位功能。
需要说明的是,在实施中,也可以使第一线圈42的电流始终朝向第二方向,并通过调节第一线圈42的电流大小,来调节导磁体41产生的第三方向的磁吸力的大小,这样,当待充电设备放置在本申请实施例提供的无线充电器的上盖板11上时,通过增大第一线圈42的电流,可以使导磁体41产生第三方向的磁吸力足够将待充电设备吸附在无线充电器的上盖板11上,从而实现磁吸对位功能。反之,当用户将待充电设备从上盖板11上取下的过程中,压敏组件3所检测到的压力值减小,使得第一线圈42的电流也减小,可以使导磁体41产生的磁吸力不足以将待充电设备牢固地吸附在无线充电器的上盖板11上,此时,用户在拿起待充电设备时,该待充电设备与无线充电器能够轻易地分离。
在实施中,导磁体41由导磁材质构成,其具体可以是容易被磁化,同时磁性又容易消磁的软铁或硅钢,这样,在第一线圈42通电时,导磁体41在电磁感应作用下产生磁力。
其中,导磁体41产生的第三方向的磁力可以是将待充电设备吸附在上盖板11上的方向,此外,在压力值小于某一预设值时,可以调节第一线圈42的电流方向,以使导磁体41产生的磁力方向用于将待充电设备推离上盖板11甚至悬浮在上盖板11上。
本实施方式中,采用第一线圈42绕设导磁体41,以通过电磁感应原理实现调节导磁体41产生的磁力的大小和方向。
当然,在实施中,控制模块2也可以基于压敏组件3所检测到的上盖板11的角度,来调节第一线圈42的电流方向和/或电流大小。
在一种可能的实现方式中,本申请实施例提供的无线充电器还包括基座(未图示),基板12与所述基座铰接;
基板12与所述基座之间形成有第一夹角,所述磁吸件4与待充电设备之 间的磁力大小与所述第一夹角正相关。
在实施中,基座可以放置在桌面上,基于基板12与所述基座的铰接结构,基板12与基座之间的第一夹角可调。
例如:假设磁吸件4用于将待充电设备吸附在上盖板11上,基板12与上盖板11层叠设置,且基座与水平面保持平行。则在基板12与水平面平行时,导磁体41只需要提供较小的吸附力便可以实现将待充电设备吸附在上盖板11上的对位效果;在上盖板11与水平面之间的夹角大于0时,导磁体41需要提供较大的吸附力才可以实现将待充电设备吸附在上盖板11上的对位效果,这样,控制模块2可以根据基板12与水平面之间的夹角来调节第一线圈42的电流大小。
本实施方式中,能够根据基板12与基座之间的夹角来调节第一线圈42的电流大小,在确保磁吸件4能够提供对待充电设备的磁吸对位效果的前提下,以尽可能地降低第一线圈42的电流大小,从而节约能耗。
可选的,如图1所示,导磁体41固定于基板12的朝向上盖板11的一侧,上盖板11上开设有通孔10,导磁体41的一端通过通孔10外露于上盖板11。
本实施方式中,通过在上盖板11上开设通孔10,使得导磁体41的远离基板12的一端通过通孔10外露于上盖板11,可以减少上盖板11对导磁体41的磁力线的屏蔽作用。
可选的,如图1、图3和图4所示,上盖板11的朝向基板12的一侧设置有突出部111,突出部111与压敏组件3正对设置;
其中,在上盖板11朝向基板12移动的情况下,突出部111压设在压敏组件3上。
在实施中,上盖板11和基板12可以通过卡扣结构滑动连接,以使上盖板11可以在一定范围内靠近或者远离基板12。
本实施方式中,上盖板11包括滑动连接的上盖板11和基板12,这样,在上盖板11承载有物体或者接收到用户的按压操作时,上盖板11会向靠近基板12的方向滑动,从而使突出部111压设在压敏组件3上,使压敏组件3 检测到上盖板11接收到的压力值。
在实施中,控制模块2、压敏组件3和磁吸件4以及充电模块5等,可以收容在上盖板11和基板12之间,以使无线充电器的外观完整。
在上盖板11朝向基板12移动的情况下,突出部111压设在压敏组件3上,并使压敏组件3发生形变。
进一步的,压敏组件3包括应变电阻或微机电系统(Microelectromechanical Systems,MEMS)电阻式压力传感器;
其中,所述应变电阻或MEMS电阻式压力传感器的目标电信号值与所述应变电阻或MEMS电阻式压力传感器发生的形变量相关,所述状态信息包括所述目标电信号值,控制模块2基于所述目标电信号值,确定所述无线充电器处于所述目标状态或非目标状态。
本实施方式中,通过设置变电阻或MEMS电阻式压力传感器,以使突出部111压设在压敏组件3上,使得所述应变电阻或MEMS电阻式压力传感器发生形变时,能够改变应变电阻或MEMS电阻式压力传感器输出的电信号值(例如:电压),这样,控制模块2可以预先存储应变电阻或MEMS电阻式压力传感器输出的电信号值与目标状态或非目标状态之间的对应关系,从而在获取到应变电阻或MEMS电阻式压力传感器输出的目标电信号值时,能够确定该目标电信号值对应的是目标状态还是非目标状态,从而得出无线充电器处于该对应的状态。这样,可以简化压敏组件3的结构。
可选的,压敏组件3设置于柔性电路板上,所述柔性电路板设置于所述基板12,在所述上盖板11接收到的朝向基板12的压力小于或等于第一预设压力值的情况下,压敏组件3在所述柔性电路板的弹性力作用下复位。
在实施中,上述第一预设压力值可以等于0或者可以大于0,在此不作具体限定。
本实施方式中,基于柔性电路板具备的弹性力,驱使变电阻或MEMS电阻式压力传感器在所述柔性电路板复位,以在变电阻或MEMS电阻式压力传感器在所述柔性电路板复位时,使控制模块2接收到表示本申请实施例提供 的无线充电器处于目标状态的状态信息。
当然,在实施中,还可以在上盖板11和基板12之间设置弹性结构,以在上盖板11上没有受到压力时,在该弹性结构提供的弹力作用下,将突出部111推离应变电阻或MEMS电阻式压力传感器,从而使应变电阻或MEMS电阻式压力传感器复位,在此不作具体限定。
在实施中,压敏组件3可以分布在基板12的不同位置,例如:如图2所示,分别在基板12的朝向上盖板11的一面上间隔设置两个压敏组件3,这样,可以在上盖板11受力不平衡时,使至少部分压敏组件3与上盖板11上的突出部111抵接,从而实现压力检测功能。
可选的,如图2所示,所述无线充电器还包括充电线圈51和充电接口52,充电接口52和充电线圈51分别与压敏组件3电连接;
其中,在压敏组件3检测到的压力值大于或等于第二预设压力值的情况下,所述无线充电器启动充电线圈51;
在压敏组件3检测到的压力值小于所述第二预设压力值的情况下,所述无线充电器关闭充电线圈51。
其中,第二预设压力值可以等于以上实施例中的第一预设压力值。
在实施中,上述充电线圈51和充电接口52可以是无线充电器内的充电模块5,上述充电线圈51可以是无线充电过程中的初级线圈,用于与待充电设备内的次级线圈进行电磁感应,从而实现无线充电。
在实施中,充电线圈51可以比第一线圈42粗,例如:充电线圈51是直径较粗的充电线圈,第一线圈42是漆包线绕制成的较细线圈。
在实施中,压敏组件3可以通过控制模块2与充电接口52和充电线圈51分别连接,控制模块2还可以根据压敏组件3的检测结果来控制充电模块5的开关,从而能够在中断对待充电设备的磁力作用的同时,停止向待充电设备充电,以及在开始对待充电设备进行磁力对位的同时,开始向待充电设备充电。当然,充电模块5也可能直接根据压敏组件3的输出信号来开启或关闭
在实施中,充电接口52可以是任意充电结构,例如:Type-C供电口,该Type-C供电口可以作为无线充电器的电源输入接口和调试接口,在实际应用中,也可通过调试接口调节磁吸件4的磁力大小和方向。
本申请实施例还提供一种充电方法,能够应用于如图1至图4所示实施例提供的无线充电器,如图5所示,该充电方法包括:
