Description

无线充放电装置 技术领域
本发明涉及无线充放电技术，具体涉及一种具备无线充电与无线放电的无线充放电装置。
背景技术
随着智能电子产品的广泛应用，智能电子产品的耗电量随着使用时间或者运行的程序逐渐增大。由此，需要为智能电子产品充电的时间与频率迅速升高。特别当使用者处于室外环境、没有电源输出端的环境或者遗忘充电设备时，而智能电子设备的电量又无法支撑用户完成必须的操作，如此极大地影响使用者的便利性，另外，有线充电设备也较为占用空间，如此也导致使用者不便于携带，进而降低了使用者的使用体验性。
发明内容
为解决目前有线充电设备使用体验性较低的问题，本发明实施例公开了一种具有较高便利性的无线充放电装置。
本发明公开一种无线充放电装置，包括储能单元、处理单元、发射控制单元、接收控制单元、第一线圈、第二线圈以及磁芯。所述储能单元电性连接所述发射控制单元与接收控制单元，所述第一线圈通过所述发射控制单元与所述处理单元电性连接，所述第二线圈通过所述接收控制单元与所述处理单元电性连接，所述第一线圈与所述第二线圈共用所述磁芯且不同时工作，当所述处理单元接收到放电信号时输出第一控制信号至所述发射控制单元与接收控制单元，所述发射控制单元响应所述第一控制信号控制所述第一线圈工作及所述接收控制单元响应所述第一控制信号控制所述第二线圈不工作，所述第一线圈配合所述磁芯将所述储能单元的电能信号向所述无线充放电装置外部发送。
相较于现有技术，无线充电装置不仅仅能够自外部接收电源信号进行存储，还能够对外输出电源信号为其他电子设备进行充电，同时，由于包括第一线圈与第二线圈两个线圈分别执行充电或者放电，从而使得充电或者放电具有相互 独立的电磁线圈，防止第一线圈与第二线圈出现电磁干扰。

为了更清楚地说明本发明实施例中的技术方案，下面将对实施例中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
下面结合附图，具体说明无线充放电装置的具体结构以及工作原理。
请参阅图1，图1为本发明第一实施例中无线充放电装置10的电路框图。本实施例中，无线充放电装置10为移动通信设备，例如手机或者平板电脑等。其中，无线充放电装置10中包括用作图像显示的显示屏以及与显示屏正的背面壳体。
如图1所示，无线充放电装置10包括储能单元11、处理单元12、发射控制单元13、接收控制单元14、第一线圈15、第二线圈16、磁芯17、重力感测单元18以及指令接收模组19。
储能单元11用于将外部提供的电能进行存储，并且将存储的电能输出给其他电子器件。
处理单元12电性连接发射控制单元13、接收控制单元14、重力感测单元18以及指令接收模组19，处理单元12用于接收充电信号或者放电信号，并且依据充电信号或者放电信号输出对应的控制信号至发射控制单元13与接收控制单元14，从而控制发射控制单13配合第一线圈15工作或者控制接收控制单元14配合第二线圈16工作。其中，充电信号与放电信号可以来自在自重力感测单元18，也可以来自指令接收模组19。
发射控制单元13电性连接第一线圈15，即第一线圈15通过发射控制单元13与处理单元12电性连接；接收控制单元14电性连接第二线圈16，第二线圈16通过接收控制单元14与处理单元12电性连接。第一线圈15与第二线圈16公用所述磁芯17且不同时工作，由此，第一线圈15与磁芯17配合产生电磁效应，第二线圈16与所述磁芯17配合产生电磁效应。本实施例中，第一线圈15与第二线圈16为漆包线。
具体地，重力感测单元18用于感测无线充放电装置10当前的位置状态，也即是依据获取的Z轴的数值来判断无线充放电装置10当前是显示屏朝上或者朝下，或者说判断无线充放电装置10当前是显示屏相较于背面壳体靠近使用者或者远离使用者。
重力感测单元18依据感测无线充放电装置10当前的位置状态输出对应的充电信号或者放电信号至处理单元12。
本实施例中，当无线充放电装置10的显示屏朝下，表示无线充放电装置10需要向外部设备输出电信号进行放电，以对外部设备进行充电，处于放电模式；当无线充放电装置10的显示屏朝上，表示无线充放电装置10接收外部设备输出电信号以对本身进行充电，处于充电模式。
那么，当重力感测单元18获取的Z轴的加速度数值的范围为-9.5～-10，则表示所述无线充放电装置10当前的位置状态为显示屏朝下，表征无线充放电装置10需要处于放电模式，由此，处于-9.5～-10的Z轴的加速度数值作为放电信号提供至所述处理单元12，对应地，处理单元12依据放电信号输出第一控制信号至发射单元13与接收控制单元14。较佳地，Z轴的加速度数值为-9.8，则表示所述无线充放电装置10当前的位置状态为显示屏朝下。
当重力感测单元18获取的Z轴的加速度数值的范围不在-9.5～-10内时，则 表示所述无线充放电装置10当前的位置状态为显示屏朝上，表征无线充放电装置10需要处于充电模式，由此，不处于-9.5～-10内的Z轴的加速度数值作为充电信号提供至所述处理单元12，对应地，处理单元12根据充电信号输出第二控制信号至发射单元13与接收控制单元14。
发射控制单元13接收到处理单元12发送的第一控制信号时控制第一线圈15工作，第一线圈15配合磁芯17将储能单元11的电能信号向无线充放电装置10外部进行发送，达到放电的目的，从而外部电子设备进行充电。此时，接收控制单元14接收到处理单元12发送的对应放电信号的第一控制信号时则控制第二线圈16停止工作。
接收控制单元14接收到处理单元12发送的对应充电信号的第二控制信号时控制第二线圈16工作，第二线圈16配合磁芯17接收来自所述无线充放电装置10外部的电信号并将该电信号转换为感应电流并传输至储能单元11进行存储，达到充电的目的。
对于重力感测单元18与处理单元12的具体配合过程如下：
无线充放电装置10预先设定的模式为充电模式，也即是无线充放电装置10默认状态为充电模式，也即是处理单元12默认接收到充电信号，并且对应输出第二控制信号至发射控制单元13与接收控制单元14，并且其中发射控制单元13控制第一线圈15暂停工作，而接收控制单元14控制第二线圈16处于工作状态。此时，若存在外部设备提供电信号时第二线圈16与磁芯17配合接收所述电信号并且通过电磁感应原理产生的感应电流传输至储能单元11。
当重力感测单元18将获得的感应数据发送给处理单元12，处理单元12根据该感应数据判定无线充放电装置10当前位置处于放电模式对应的显示屏朝下后，表明处理单元12接收到放电信号，无线充放电装置10便由充电模式进入放电模式，也即是处理单元12对应放电信号输出第一控制信号至发送控制单元13与接收控制单元14，以启动第一线圈15处于工作状态，而控制第二线圈16暂停工作。
较佳地，无线充放电装置10可输出提示信息以通知使用者当前无线充放电装置10处于放电模式，例如从显示屏输出显示相应的提示信息或者设置充电指示灯如放电指示灯进行显示。同时，充电指示灯与放电指示灯的闪动频率相 同，其中，放电指示灯在无线充放电装置10进入放电模式时开启并且按照预定频率闪烁，放电指示灯的闪动频率可以预先设定。
较佳地，在第一预设时间内，当重力感测单元18判定无线充放电装置10放电状态对应的位置状态均未改变，且无线充放电装置10与待充电的电子设备符合预设条件时，例如二者位于预设距离或者相互发送验证信息验证成功时，也即是握手成功后，无线充放电装置10则保持放电模式不变。
较佳地，无线充放电装置10与待充电的电子设备不符合预设条件时，无线充放电装置10在第二预设时间内保持放电模式，当超过第二预设时间，无线充放电装置10与待充电的电子设备仍然不符合预设条件，则无线充放电装置10切换至充电模式；当在第二预设时间内，无线充放电装置10与待充电的电子设备重新符合预设条件，则无线充放电装置10仍然保持放电模式。
较佳地，当重力感测单元18判定无线充放电装置10放电状态对应的位置状态改变，例如变换为显示屏朝上，但此时并无符合预设条件的待充电电子设备存在，无线充放电装置10在第二预设时间内保持放电模式，并且依据预先设定的放电阈值进行放电。放电阈值可以依据实际需要进行设定，例如30％、50％、80％、100％。若在第一预设时间内，无线充放电装置10与待充电的电子设备符合前述预设条件，则无线充放电装置10仍然保持放电模式。此时充电指示灯与参考指示灯的闪动频率相同。
指令接收模组19接收使用者的操作而生成与该操作相对应的操作指令，并且依据该操作指令输出对应的充电信号或放电信号至处理单元12。本实施例中，指令接收模组19为按键开关或者触摸屏。
请参阅图2，其为如图1所示第一线圈15与第二线圈16的平面结构示意图。
第一线圈15与第二线圈16均设置于磁芯17的一侧，并且均位于同一平面内。其中，第一线圈15与第二线圈16相互绝缘。
同时，第一线圈15包括第一导电端151与第二导电端152。其中，第一导电端151固定于中心参考点O1附近，然后，第一线圈15自第一导电端151开始相对于中心参考点O1呈矩形地环绕设置，然后第二导电端152设置于第一线圈15的最外侧。
第二线圈16在第一线圈15整体的外侧相对于中心参考点O1呈矩形地环绕 设置。其中，第二线圈包括第三导电端161与第四导电端161，第三导电端161自邻近第二导电端152的位置开始相对于中心参考点O1呈矩形地环绕设置，由此，第四导电端161位于第一线圈15以及第二线圈16整体的最外侧。
由此，第一导电端151、第二导电端152以及第三导电端161自第一线圈15以及第二线圈16内部延伸到第二线圈16外侧，以便于与其他单元电性连接，当然，第四导电端162则直接位于第二线圈17外侧。
可变更地，请参阅图3，其为一变更实施例中第一线圈25与第二线圈26的平面结构示意图。
本实施例中，第一线圈15与第二线圈16相对于中心参考点O1交替环绕设置。
具体地，第一线圈15的第一导电端151与第二线圈16的第三导电端161均在邻近中心参考点O1的位置固定，并且同步开始相对于中心参考点O1呈矩形地环绕设置，由此，第一线圈15的第二导电端152与第二线圈16的第四导电端162均相邻地位于第一、第二线圈15、16的最外侧。
相较于现有技术，无线充电装置30不仅仅能够自外部接收电源信号进行存储，还能够对外输出电源信号为其他电子设备进行充电，同时，由于包括第一线圈15与第二线圈16两个线圈分别执行充电或者放电，从而使得充电或者放电具有相互独立的电磁线圈，防止第一线圈15与第二线圈16出现电磁干扰。
请参阅图4，其为本发明第二实施例中无线充电装置30的整体结构示意图。
如图4所示，无线充电装置30为背包，其包括的电路供电源与第一实施例中作为无线充放电装置基本相同，区别仅在于第一线圈35、第二线圈36以及磁芯37的形状结构。其中，第一线圈35、第二线圈36以及磁芯37位于背包30的一侧。
请参阅图5，其为如图4所示第一线圈35、第二线圈36以及磁芯37的侧面结构示意图。
如图5所示，第一线圈35与第二线圈36分别位于磁芯37的相对两侧。具体地，磁芯37包括相邻设置的第一子磁芯371与第二子磁芯372，第一线圈35设置于第一子磁芯371远离第二磁芯372的一侧，第二线圈36设置于第二子磁芯372远离第一子磁芯371的一侧。
较佳地，无线充电装置30还包括散热元件301，散热元件301设置于第一子磁芯371与第二子磁芯372之间，也即是散热元件301位于第一子磁芯371邻近第二子磁芯372的一侧，同时，散热元件301也位于第二子磁芯372邻近第一子磁芯371的一侧。也即是，第一子磁芯371与第二子磁芯372共用一个散热元件301。
如此一来，即可通过背包在外出而没有其他电源时即可通过指令接收模组(图未示)来控制充电或者放电。例如，背包位于室内环境或者具有无线充电设备时即可针对其执行充电，而位于室外环境或者不具有其他充电设备时，即可通过背包给待充电的电子设备进行充电。
本文中应用了具体个例对本发明的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本发明的核心思想；同时，对于本领域的一般技术人员，依据本发明的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本发明的限制。
