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。
本申请实施例提供了一种无线充电设备。请参照图1至图6,无线充电设备包括电源(图未示)、控制系统(图未示)、驱动机构(图未示)及至少一个天线模组10,所述电源与所述控制系统连接,所述控制系统与所述驱动机构连接,所述驱动机构与所述至少一个天线模组连接,每一个所述天线模组包括天线阵列结构12及与所述天线阵列结构连接的馈电网络11,所述馈电网络11与所述控制系统连接;其中,所述馈电网络11用于对所述天线阵列结构12馈电,以使所述天线阵列结构12发射电磁波,所述驱动机构用于驱动目标天线模组运动,以使所述目标天线模组中的天线阵列结构12产生的电磁波覆盖待充电设备,所述目标天线模组为所述天线阵列结构12产生了电磁波的天线模组。
可选地,无线充电设备可以是设有基座20,所述基座20包覆有金属外壳以形成密闭的收容空间,所述电源及控制系统可以是设于该收容空间内。所述驱动机构也可以是位于基座20的收容空间内,或者也可以是设置在基座20外。控制系统与驱动机构连接,也就能够控制驱动机构运转,驱动机构的运转能够驱动所述至少一个天线模组中的一个或多个天线模组10(也即目标天线模组)运动,以使得一个或多个天线模组10运动至目标位置。其中,被 驱动机构驱动的一个或多个天线模组10,这些天线模组10所包括的天线阵列结构12产生了电磁波,进而这些天线模组10也就能够发射电磁波,驱动机构用于驱动这些天线模组10运动至目标位置,该目标位置下,这些天线模组10中的天线阵列结构12产生的电磁波的发射方向覆盖待充电设备,进而以对待充电设备实现无线充电。需要说明的是,天线发射电磁波以对电子设备实现无线充电的原理可以是参照相关技术,本申请实施例不做赘述。
可选地,驱动机构能够驱动所述至少一个天线模组10中的一个或多个天线模组10运动,所述目标天线模组的数量也就可以是一个或多个。其中,所述驱动机构可以是驱动目标天线模组转动或者是移动。
本申请实施例中,驱动机构与至少一个天线模组连接,进而无线充电设备也就能够根据待充电设备的位置或者数量,通过驱动机构选择性地驱动其中一个或多个天线模组10运动,以使得所述一个或多个天线模组10产生的电磁波能够覆盖待充电设备,这样也就能够更加灵活地选择需要进行电磁波发射的天线模组,进而无论待充电设备位于无线充电设备的哪个方位,都能够使待充电设备位于电磁波的覆盖范围内以实现无线充电,无需将待充电设备放置在特定位置,使得无线充电设备对待充电设备的无线充电方式更加灵活,为用户提供更好的无线充电体验。
需要说明的是,控制系统可以是在有待充电设备需要充电的情况下,才控制馈电网络11对天线阵列结构12馈电,以使天线阵列结构12发射电磁波,而实现对待充电设备充电。若没有待充电设备需要充电,则控制系统控制馈电网络11停止对天线阵列结构12馈电,天线阵列结构12也就不会发射电磁波,以降低电磁波辐射对人体的损害。
可选地,无线充电设备包括用于感应待充电设备方位的感应器(图未示),所述感应器与所述控制系统连接。可以理解地,现有的电子设备大多设有红外发射装置和红外接收装置,所述感应器可以是设置在基座20顶部的红外线接收器;当待充电设备有无线充电需求时,待充电设备可以是调用其内部的红外发射装置,向外发射经调制的脉冲红外编码,无线充电设备上的红外接 收器接收到该脉冲红外编码后进行解调,并基于脉冲红外编码确定待充电设备的第一位置,进而控制系统根据待充电设备的第一位置,控制与该第一位置对应的目标天线模组中的馈电网络11对其连接的天线阵列结构12馈电,以使得天线阵列结构12产生覆盖待充电设备的电磁波,以实现对待充电设备的无线充电。另外,控制系统还用于根据待充电设备所处的第一位置,控制相应的天线模组10转动,以确保待充电设备位于目标天线模组发射的电磁波的覆盖范围内。
进一步地,每一个所述天线模组10包括至少一个馈电网络11,每一个所述馈电网络11与所述控制系统连接,所述控制系统用于控制目标馈电网络与所述天线阵列结构12连接,以使所述天线阵列结构12发射电磁波,所述目标馈电网络为至少一个馈电网络11中的任一个;其中,不同的馈电网络11用于使所述天线阵列结构12发射不同扫描角度的电磁波。可以理解地,电磁波的扫描角度也可以理解为电磁波的辐射角度,或者说辐射范围。
本申请实施例中,一个馈电网络11对应一个扫描角度。如图2所示,一个天线模组10包括4个馈电网络11,分别为第一馈电网络111、第二馈电网络112、第三馈电网络113及第四馈电网络114。其中第一馈电网络111对应的扫描角度为0度,第二馈电网络112对应的扫描角度为30度,第三馈电网络113对应的扫描角度为60度,第四馈电网络114为圆极化馈电网络。第一馈电网络111在激励天线阵列产生电磁波时,电磁波的扫描角度为0度,也即电磁波的发射方向直接朝向前方不发生偏移;第二馈电网络112在激励天线阵列产生电磁波时,电磁波的发射方向偏移30度;第三馈电网络113在激励天线阵列产生电磁波时,电磁波的发射方向偏移60度。这样,也就能够通过不同的馈电网络11激励天线阵列结构12产生电磁波,使得天线阵列结构12能够实现0到60度的扫描,也即电扫。当然,馈电网络11对应的扫描角度也可以是其他角度,例如天线模组10包括两个馈电网络11,分别对应的扫描角度为0度和45度;或者天线模组10对应4个馈电网络11,分别对应的扫描角度为0度、25度、50度和75度,等。
可选地,不同的馈电网络11对应不同的电长度,以使所述天线阵列结构12发射不同扫描角度的电磁波。本申请实施例中,所述馈电网络11在对天线阵列结构12馈电时,所述馈电网络11与天线阵列结构12可以是形成偶极子天线,通过调整偶极子天线馈电口大小,优化偶极子天线的长度和宽度,使其在扫描到预设角度时增益仅比不扫描时下降3dB,进而能够有效满足无线充电覆盖广的要求。其中,所述预设角度可以是用户在优化过程中预先设定的扫描角度,例如预设角度可以是馈电网络11对应的扫描角度,或者预设角度也可以是定值,如60度。
需要说明地,在偶极子天线的优化过程中,可以是以偶极子天线在扫描到预设角度时增益比不扫描时下降3dB为优化准则,对偶极子天线的长度和宽度进行调整。本申请实施例中,天线阵列结构12中的天线单元122的长度和宽度是一定的,进而也就是通过调整馈电网络11的电长度来实现对偶极子天线长度的调整。其中,不同的馈电网络11对应不同的电长度,以使得天线阵列结构12能够发射不同扫描角度的电磁波。
请进一步参照图3和图4,天线阵列结构12包括基板121及设于所述基板121上的若干个天线单元122,所述若干个天线单元122阵列排布以形成天线阵列;其中,所述天线单元122包括第一天线元件1221和第二天线元件1222,所述第一天线元件1221的长度方向与所述第二天线元件1222的长度方向垂直。
如图4所示,第一天线元件1221可以是由两个金属贴片组成,这两个金属贴片之间设有间隙;第二天线元件1222也可以是由两个金属贴片组成,这两个金属贴片之间也设有间隙。第一天线元件1221和第二天线元件1222形成类似十字型的结构,也即第一天线元件1221与第二天线元件1222垂直,进而在连接馈电网络11的情况下,第一天线元件1221和第二天线元件1222能够形成垂直极化天线、交叉极化天线或圆极化天线。这样也就能够有效扩展天线模组10的极化形式,以使得天线模组10能够根据需要发射不同角度方向的电磁波,以实现电磁波对待充电设备的覆盖,更好地实现无线充电。
可选地,第一天线元件1221的长度与第二天线元件1222的长度相同,第一天线元件1221的长度可以是基于天线模组10工作的频段来确定。例如,天线模组10的工作频段为20GHz,点频天线的工作由于不受到带宽的制约,第一天线元件1221的长度设定为天线模组10在该频段下不出现栅瓣的最大电长度,也即λ/2=7.5mm,其中,λ为当前口径面天线的工作波长,也就是20GHz频段下天线的工作波长。
需要说明地,电磁波在路径传播时,提升工作频率会使得路径衰减增大,但口径面积为S的相控阵天线最大增益为4πS/λ 2,其中,λ为当前口径面天线的工作波长,提升工作频率使得λ减小。本申请实施例中,天线阵列结构12包括若干个天线单元122,进而同一面积下半波长单位大小的天线单元122数量增大时,增益也有所提升,最终增益的相对增大值和路径损耗的相对增大值抵消,解决了高频路径下损耗大的问题。
本申请实施例中,若干个天线单元122阵列排布在基板121上以形成天线阵列。如图3所示,天线单元122的数量为64个,以8×8的阵列形式排布于基板121上。当然,天线单元122的数量还可以是其他的可能形式,本申请实施例不做具体限定。
进一步地,所述控制系统用于控制所述馈电网络11对所述第一天线元件1221及所述第二天线元件1222中的任意一者馈电,以激励所述天线单元122形成单极化天线;或者,所述控制系统用于控制所述馈电网络11对所述第一天线元件1221及所述第二天线元件1222馈电,以激励所述天线单元122形成双极化天线或圆极化天线。
例如,控制系统可以是控制馈电网络11与天线阵列结构12中所有的第一天线元件1221连接,以对第一天线元件1221馈电形成单极化天线,单极化天线能够产生特定辐射方向的电磁波,同样能够实现对待充电设备的无线充电,且单极化天线不易受到干扰。
或者,控制系统也可以是控制馈电网络11对第一天线元件1221和第二天线元件1222馈电以形成双极化天线或圆极化天线。这样,也就使得天线模 组10能够实现对不同角度方向的电磁波辐射,以实现对待充电设备的无线充电。
本申请实施例中,驱动机构能够驱动所述至少一个天线模组10中的一个或多个天线模组10运动,其中所述运动包括转动和移动。
在一种可选的实施方式中,所述驱动机构用于驱动所述目标天线模组转动,进而以使得天线模组10的辐射方向发生改变。例如,所述至少一个天线模组10的数量为一个,若待充电设备位于该天线模组10的后方,则驱动机构可以是驱动该天线模组10转动,以使得该天线模组10朝向待充电设备,进而使得该天线模组10的天线阵列结构12产生的电磁波能够覆盖待充电设备,以实现对待充电设备充电。
或者,若至少一个天线模组10的数量大于一个,驱动机构也可以是驱动其中一个或多个天线模组10转动。例如,待充电设备朝向其中一个天线模组10,但是待充电设备位于该天线模组10的电磁波扫描角度之外,则驱动机构可以是驱动该天线模组10转动,以使得该天线模组10的电磁波扫描角度覆盖待充电设备。或者,若存在多个待充电设备,且不同的待充电设备朝向不同的天线模组10,则驱动机构也可以是控制多个天线模组10转动,以使得每一个待充电设备都能够位于相应天线模组10的电磁波扫描角度的覆盖范围内,以使得无线充电设备能够同时对多个待充电设备实现无线充电。
可选地,天线模组10可以是设有对应的转盘,驱动机构可以是通过控制转盘转动来实现天线模组10的转动,驱动机构可以是设有与转盘啮合的齿轮,通过齿轮的转动来控制转盘的转动。当然,驱动机构控制天线模组10转动,还可以是有其他可能的实现形式,本申请实施例不做过多列举。
在另一种可选的实施方式中,驱动机构还可以是驱动天线模组10移动,以使得天线模组10发生位置变化。可选地,所述无线充电设备包括至少两个天线模组10,所述驱动机构用于驱动所述至少两个天线模组10运动并拼接形成一个所述目标天线模组。
为更好地理解本实施方式中天线模组10的移动,以下将以图1和图2中 所示的无线充电设备包括四个天线模组10为例进行说明,如图1和图2所示,四个天线模组10分别设置在基座20四周的不同方向上。
在一种情景下,当无线充电设备的感应器接仅接收到一台待充电设备的充电请求时,控制系统可以是控制驱动机构运转,以驱动四个天线模组10移动并拼接形成一个大的目标天线模组。如图5所示,四个天线模组10展开合一形成一个更大的天线模组,增大了天线单元122数目,有效降低了波束宽度的同时提高了天线的总增益,使得该情景下的电功率提升。其中,展开拼接形成的目标天线模组的天线增益相较于单个的天线模组10提升了6dB,则无线充电设备的电源可以通过降低6dB发射功率来保证和单个天线模组10输出到达待充电设备的功率相同。相较于单个天线模组10,四合一拼接形成的目标天线模组功耗降低为单个天线模组10的25%,进而为无线充电设备提高增益的同时,还能够有效地降低整体功耗。
另外,四合一拼接形成的目标天线模组增益为单个天线模组10的4倍,而波束宽度降低10~17度,相应会在天线外围减少一定的辐射面积,这样也就增加了指向方位辐射增益,更有益于做到为待充电设备的精准充电,同时在非充电空间可以降低辐射量,确保用户使用安全。
或者,在无线充电设备包括至少两个天线模组10的情况下,驱动机构用于驱动所述至少两个天线模组10运动以形成至少两个所述目标天线模组,每个所述目标天线模组中的天线阵列结构产生的电磁波分别覆盖不同的区域。可选地,所述至少两个目标天线模组间隔设置;或者,所述至少两个目标天线模组相连接。
例如在另一种情景下,当无线充电设备的感应器接接收到多台待充电设备的充电请求时,控制系统根据充电请求确定各待充电设备的方位,若方位较少,则控制系统可以是控制驱动机构运动,以驱动天线模组10移动至使得每两个天线模组10拼接形成一个新的目标天线模组,如图6所示,两个目标天线模组相对设置。或者,二合一拼接形成的两个目标天线模组也可以是相连接,如两个目标天线模组成V型设置。
这种情景下,二合一拼接形成的目标天线模组相较于单个天线模组10的天线增益增大了3dB,则无线充电设备的电源可以通过降低3dB发射功率来保证和单个天线模组10输出到达待充电设备的功率相同,进而二合一拼接形成的目标天线模组功耗降低为单个天线模组10的50%,提高了无线充电设备的增益,还能够有效地降低无线充电设备的整体功耗。
在另一种场景下,根据多个待充电设备的方位,控制系统也可以是控制天线模组10移动,以使得其中三个天线模组10移动至拼接形成一个目标天线模组,另一个天线模组10移动至相应位置以朝向待充电设备。相应地,三合一拼接形成的目标天线模组同样能够提供无线充电设备的增益,并有效降低无线充电设备的整体功耗。
可选地,请参照图1,在一种场景下,无线充电设备的四个天线模组10也可以是单独工作,四个天线模组10也可以是运动至拼接形成如图1所示的四方体结构,每一个天线模组10分别负责90度范围内的设备充电,如此可以兼顾对四周的待充电设备充电需求,进而实现360度的充电全覆盖,使得无线充电设备的具有更大的无线充电范围,使得无线充电更加便捷,为用户提供更好的无线充电体验。
这样,无线充电设备能够根据待充电设备的充电请求,来确定待充电设备的方位或者说位置,通过控制系统控制驱动机构运转,进而驱动机构能够控制一个或多个天线模组10移动并拼接形成更大的天线模组,这样的设计使得无线充电设备的电磁波辐射方向及辐射角度不再是固定不变的,无线充电设备能够根据待充电设备的方位和位置来灵活调整天线模组10的位置和方向,实现高效充电,使得无线充电更为灵活,为用户提供更好的无线充电体验。并且,拼接形成的天线模组能够具有更大的天线增益,同时无线充电设备的功耗更低。
可选地,各天线模组10与驱动机构可以为可拆卸连接,进而更加方便无线充电设备的携带和组装。
本申请实施例中,所述无线充电设备还包括菲涅耳透镜(图未示),所述 菲涅耳透镜与所述控制系统连接。所述菲涅耳透镜用于检测人体发出的固有长波段红外,当菲涅耳透镜检测到人体的长波段红外后,向控制系统发送反馈信号,控制系统可以是断开馈电网络11对天线阵列结构12馈电,进而以停止产生电磁波,确保用户安全。可以理解地,当菲涅耳透镜未检测到人体发出的固有长波段红外,说明此时附近不存在用户,则无线充电设备可以是正常启用。
本申请实施例还提供了一种充电方法,该充电方法应用如如上所述的无线充电设备。如图7所示,所述充电方法包括以下步骤:
步骤701、接收待充电设备发送的充电请求。
可选地,所述充电请求可以是无线信号,如蓝牙信号、红外信号等。
本申请实施例中,无线充电设备可以是设有红外线接收器,当待充电设备有无线充电需求时,待充电设备可以是调用其内部的红外发射装置,向外发射经调制的脉冲红外编码,也即充电请求,进而无线充电设备通过红外接收器接收到该脉冲红外编码,并进行解调。
步骤702、基于所述充电请求确定所述待充电设备的第一位置。
可选地,无线充电设备基于接收到的充电请求,例如基于上述脉冲红外编码,根据其发送方向也就能够确定待充电设备所处的方位,也即第一位置。
步骤703、基于所述第一位置确定目标天线模组,控制所述目标天线模组中的馈电网络对连接的天线阵列机构馈电,并控制目标天线模组运动至第二位置,以使所述目标天线模组中的天线阵列结构产生的电磁波覆盖所述第一位置,以对所述待充电设备充电;
其中,所述目标天线模组为所述至少一个天线模组中的至少一个。
本申请实施例中,无线充电设备确定出待充电设备的第一位置后,基于第一位置确定与其对应的目标天线模组,例如待充电设备位于无线充电设备的左侧,则将无线充电设备左侧的天线模组确定为目标天线模组。进一步地,控制目标天线模组中的馈电网络对该天线模组中的天线阵列结构馈电,并控制目标天线模组运动至第二位置,例如控制目标天线模组转动至其中心正对 待充电设备,进而以使得目标天线模组产生的电磁波覆盖待充电设备所处的第一位置,以对所述待充电设备充电。其中,无线充电设备控制目标天线模组运动的具体实现方式可以参照上述实施例中的描述,此处不再赘述。
这样,无线充电设备能够根据待充电设备所处的第一位置,来确定目标天线模组,并能够控制目标天线模组运动至与第一位置相应的第二位置,目标天线模组的运动及拼接方式可以是参照上述无线充电设备实施例中的具体描述,如图1、图5和图6所示的可选拼接方式。进而,无论待充电设备位于无线充电设备的哪个方位,都能够使待充电设备位于电磁波的覆盖范围内以实现无线充电,无需将待充电设备放置在特定位置,使得无线充电设备对待充电设备的无线充电方式更加灵活,为用户提供更好的无线充电体验。
可选地,在每一个所述天线模组包括至少一个馈电网络的情况下,所述,控制所述目标天线模组中的馈电网络对连接的天线阵列机构馈电包括:
基于所述第一位置确定目标馈电网络,控制所述目标天线模组中的目标馈电网络对连接的天线阵列结构馈电;
其中,所述目标馈电网络为至少一个馈电网络中的任一个。
需要说明地,不同的馈电网络用于使所述天线阵列结构发射不同扫描角度的电磁波,也就是说,一个馈电网络对应一个扫描角度。无线充电设备在确定出待充电设备的第一位置后,确定出与第一位置最匹配的目标馈电网络,进而控制目标天线模组中的目标馈电网络对其连接的天线阵列结构馈电,以产生该目标馈电网络对应的扫描角度的电磁波,以使得电磁波覆盖第一位置。
例如,一个天线模组包括4个馈电网络,其中3个馈电网络对应的扫描角度分别为0度、30度和60度,若检测到第一位置处于目标天线模组的80度扫描范围内,则可以是将对应的扫描角度为60度的馈电网络确定为目标馈电网络,进而控制该馈电网络对天线阵列结构馈电,天线模组产生60度扫描角度的电磁波;此时电磁波仍然没有覆盖第一位置,则进一步控制驱动机构运转,以驱动目标天线模组转动一定角度,使得电磁波覆盖第一位置,进而实现对待充电设备的无线充电。
这样,无线充电设备也就能够基于待充电设备所处的位置,选择与第一位置匹配的目标馈电网络来对天线阵列结构馈电,进而使得无线充电设备能够更加灵活地选择馈电方式。
可选地,所述控制目标天线模组运动至第二位置包括:

可选地,在所述无线充电设备包括菲涅耳透镜的情况下,所述方法还包括:
在基于所述菲涅耳透镜检测到预设范围内存在目标红外波长的情况下,控制所述目标天线模组中的馈电网络停止对天线阵列结构的馈电。
其中,所述菲涅耳透镜用于检测人体发出的固有长波段红外,当基于菲涅耳透镜检测到人体的长波段红外(以及目标红外波长)后,则无线充电设备可以是断开目标天线模组中馈电网络对天线阵列结构馈电,进而以目标天线模组停止产生电磁波,这样以避免电磁波对人体的辐射伤害,确保用户安全。可以理解地,当菲涅耳透镜未检测到人体发出的目标红外波长,说明此时附近不存在用户,则无线充电设备可以是正常启用。
本申请实施例还提供了一种充电装置,所述充电装置可以是无线充电设备中的一个功能模块或者说装置,或者也可以是所述无线充电设备,可以是 包括如上所述无线充电设备实施例中的全部技术特征。
