Description

一种超声波无线充电转接头及其充电方法 技术领域
本发明涉及一种电磁场能量交换领域，特别涉及一种超声波无线充电转接头及其充电方法。
背景技术
随着生活中的电子设备越来越多，在不知不觉中各种“理不清”的线缆以及需要事先布置好的插座却给我们带来了与日俱增的困扰。无线充电技术是利用磁共振、电磁感应线圈、无线电波(无线电磁波)等方式，在充电器与设备之间的空气中传输电荷，实现电能高效传输的技术。
它主要包括电磁感应式、无线电波式、磁场共振式，以及其他方式(微波、超声波、激光)。市场上有几个相互竞争的无线充电标准，未来的趋势将致力于整合磁共振和磁感应技术，实现多种模式的充电方式。其中，消费电子产品需求的迅速增长也是无线充电市场飞速发展的主要原因。此外，汽车领域，尤其是电动汽车的发展也将对无线充电市场起到积极的促进作用。

当在手机、音箱或其他需要充电的设备中，当使用转接头，可以同时进行有线高速充电，当进行超声波能量转换的无线充电，还可以改善现有技术中存在的问题。

本发明提供了一种超声波无线充电转接头及其充电方法，为了解本发明的特征、内容与优点及其所能达成的功效，则将本发明结合附图，并以实施例的表达形式详细说明如下，而其中所使用的附图，其主旨仅为示意及辅助说明书用，未必为本发明实施后的真实比例与精准配置，故不应就附图的比例与配置关系解读、局限本发明于实际实施上的权利范围。

本发明是通过采用一种转接头3，来对待充电设备2进行充电，且充电模式是无线充电，因为转接头3可以进行超声波能量转换，从而实现无线充电。
图2为本发明的超声波无线充电装置示意图，本发明的转接头3与待充电设备2连接，转接头3还可以通过无线传输，与超声波发生器1进行无线通信，实现对待充电设备2进行无线充电。
图4是本发明的转接头组成示意图；如图4所示，本发明的转接头3主要包含无线接头模块4和接口输出模块5，信号经过转接头3的无线接头模块4处理后，经接口输出模块5输出的电流给待充电设备2进行充电。
图3是本发明的超声波无线充电的流程示意图；如图3所示，通过本发明的超声波无线充电装置，可以实现的超声波无线充电的方法具体为：
a：超声波发生器1开始工作，从而发射出超声波；
b：由超声波发生器1发射的该超声波，通过无线传输方式，使超声波信号被传输至转接头3中的无线接头模块4；
c：无线接头模块4接收超声波，并对超声波进行声电转换处理过程；
d：超声波经过声电转换后最终得到直流电流，经接口输出模块5输出，从而实现给待充电设备2的无线充电。
其中，超声波发生器1可以产生超声波。超声波发生器1是把市电转换成与超声波换能器相匹配的高频交流电信号，驱动超声波换能器工作，该信号可以是正弦信号，也可以是脉冲信号，这个特定频率就是该换能器的频率。
所以超声波发生器1实质上是先将电力转换成音频信号，然后通过介质以超声波的形式进行传输；与之相匹配的信号接收模块6会捕捉到该超声波信号，然后会将其再转换成电信号。
图5本发明的转接头内部结构示意图，如图5所示，本发明转接头3的无线接头模块4包含信号接收模块6、信号处理模块7和整流模块8。
该信号接收模块6与超声波发生器1为无线通信连接，信号接收模块6用于接收由超声波发生器1发射的超声波信号。
信号处理模块7与信号接收模块6通信连接，信号处理模块7用于处理从信号接收模块6中输出的超声波信号，将该超声波信号处理转换成电流信号，其中，此时的电流信号为交流电信号。
信号处理模块7将超声波转换成电信号，实质上将机械振动波转换成电信号，其可以利用压电材料的压电效应来实现的。
压电效应就是电介质沿一定方向上受外力作用而变形时，会在它的两个相对表面上出现正负相反的电荷。当外力去掉，它又会恢复到不带电的状态。
例如，压电陶瓷，其利用其材料在机械应力作用下，引起内部正负电荷中心相对位移而发生极化，导致材料两端表面出现符号相反的束缚电荷即压电效应而制作，具有敏感的特性，从而可应用于本发明中的信号处理模块7。
若要对待充电设备2进行充电，仍需要将交流电转换成直流电，所以还需要整流过程将该交流电转换成直流电，实现对待充电设备2的无线充电。
信号处理模块7与整流模块8通信连接，整流模块8用于对信号处理模块7输出的交流电流进行整流处理，将交流转换成直流，从而对待充电设备2进行充电。
所以本发明的超声波无线充电的信号传输过程为：
启动声波发生器1，超声波发生器1开始进行工作，发射出超声波信号。所发射的超声波信号，通过无线传输将超声波信号传输至无线接头模块4中的信号接收模块6，信号接收模块6接收该超声波信号后，并传输至信号处理模块7。
信号处理模块7接收到了信号接收模块6提供的超声波信号，信号处理模块7再对该超声波信号进行处理，将超声波信转换成电流信号；其中，转 换后的电流信号为交流电信号。
但是要对待充电设备2进行充电，仍需要将交流电转换成直流电，所以需要整流过程。
信号处理模块7将交流电信号传送至整流模块8，整流模块8将其接收到的交流电进行整流处理，转换成直流电，并将直流电输出至本发明公共的接口输出模块5，从而实现了对待充电设备2进行无线充电过程。
本发明的超声波无线充电转接头及其充电方法可应用的待充电设备2可以是手机、音箱、平板、或其他需要充电的设备。
本发明的接口输出模块5可以为USB接口，或Type-C接口，或Lightning接口或者其他类型的接口。
示例地，本发明的转接头3可用于超声波无线充电模式中，还可以设计成多用式转接头，例如两用式转接头，或者三用式转接头，或其他的转接头等。具体如下：
例如，本发明的转接头3可以为两用式转接头；如图6所示，图6为本发明的有线和无线结合的一种两用式转接头组成示意图。
两用式转接头包含有线接头模块9、无线接头模块4和公共的接口输出模块5，经过有线接头模块9和无线接头模块4处理后，输出的电流汇集到一个公共的接口输出模块5，从而实现给待充电设备2进行充电。其具体充电方法为：
有线充电；供电的电源通过有线传输，经过转接头3中的有线接头模块9后，直接给待充电设备2进行直充充电。
超声波无线充电：超声波发生器1发射超声波，超声波经过无线传输至转接头3中的无线接头模块4进行信号接收处理，从而实现给待充电设备2的无线充电。
上述的有线充电和超声波无线充电的两用式转接头的具体实施操作过程为：
通过控制一个智能开关，使得该智能开关可同时开启无线充电模式和有线充电模式；无线充电模式的开启决定超声波发生器1是否进行工作；再设置一个有线元件开关电路模块来启动或关闭有线充电模式。
对于无线充电而言，发射的超声波信号通过无线被传输至无线接头模块4中的信号接收模块6，信号接收模块6接收超声波信号后，再输出至信号处理模块7，信号处理模块7对该超声波信号进行处理，将其转换成电流信号；其中，转换后的电流信号为交流电信号。
若要对待充电设备2顺利进行充电，仍需要将上述交流电转换成直流电，所以还需要整流过程。
信号处理模块7将交流电信号传送至整流模块8，整流模块8将其接收到的交流电进行整流处理，转换成直流电，并将该直流电输出至本发明的公共的接口输出模块5，从而实现了对待充电设备2进行无线充电过程。
对于有线充电而言，电源与有线元件开关电路模块连接，有线接头模块9的控制电路模块通过开启的有线元件开关电路模块，获得了来自于电源的直流电，直流电经过公共的接口输出模块5，从而实现了对待充电设备2进行有线充电过程。
两用式转接头的充电模式可以通过智能开关来控制选择，从而决定待充电设备2的充电模式。
示例地，本发明的转接头3可以为三用式转接头；转接头3设有第一无线接头模块41、第二无线接头模块42和有线接头模块9，如图7所示。
其中，第一无线接头模块41用于超声波声波信号的接收和处理，对待充电设备2进行超声波无线充电。
第二无线接头模块42可用于电磁波信号的接收和处理，对待充电设备2进行电磁波进行无线充电。或者，第二无线接头模块42可用于对待充电设备进行电磁感应无线充电模式。
有线接头模块9用于对待充电设备2进行有线充电，最终该三用式转接 头可实现三种充电模式对待充电设备2进行充电。三用式转接头的充电模式可通过一种智能开关来控制选择，从而决定待充电设备2的充电模式。
图8是本发明的有线、电磁波无线和超声波无线结合的三用式转接头组成示意图；如图8所示，第一无线接头模块41设为超声波接头模块，第二无线接头模块42设为电磁波接头模块，电磁波模式的无线充电的过程具体为：
当无线充电方式为电磁波无线充电时，对于超声波充电而言，需要将超声波发生器变成电磁波发射器。
电磁波接收装置也需要与电磁波发射器进行相匹配，使其发射的电磁波信号，并通过无线电磁波传输方式来传输至对应的转接头中设置的电磁波接头模块(包含电磁波信号接收模块和电磁波信号处理模块)。
第二无线接头模块42还可将电磁波信号转换成电流。电磁波无线充电，适合远距离小功率充电，可随时随地进行充电，但是转换效率较低。
图9是本发明的有线、电磁感应无线和超声波无线结合的三用式转接头组成示意图；如图9所示，第一无线接头模块41为超声波接头模块，第二无线接头模块42为电磁感应接头模块；电磁感应模式的无线充电的过程具体为：
当无线充电方式为电磁感应无线充电时，对于超声波充电而言，需要将超声波发生器变成线圈模块，电流通过线圈，线圈产生磁场，对附近线圈的产生感应电动势，产生电流。在转接头3中的电磁感应接头模块对应设有可产生电流的线圈，所以无线传输方式变成了电磁感应方式。从而实现对待充电设备2进行无线充电。电磁感应无线充电适合短距离充电，转换效率较高，但会限定充电摆放位置。
尽管本发明的内容已经通过上述优选实施例作了详细介绍，但应当认识到上述的描述不应被认为是对本发明的限制。在本领域技术人员阅读了上述内容后，对于本发明的多种修改和替代都将是显而易见的。因此，本发明的保护范围应由所附的权利要求来限定。
