在本发明的一实施例中，上述的阵列式无线能量转换装置还包括多个导磁性材料，其中这些导磁性材料分别配置于这些线圈单元内。
在本发明的一实施例中，上述的各线圈单元具有几何中心及半径，半径是几何中心至边的最短距离，相邻的两线圈单元的两几何中心的距离大于半径的两倍且小于半径的二分之五倍。
在本发明的一实施例中，上述的各线圈单元的几何中心位于其他各线圈单元之外。
本发明的阵列式无线能量转换装置的设计方法包括以下步骤。决定线圈单元的形状。依据线圈单元的形状而决定几何中心不相同的多个线圈单元的排列方式，以使各线圈单元的至少一个边相邻于另一线圈单元的一个边，其中这些线圈单元构成第一图案化导电层。依据这些线圈单元的排列方式而决 定各线圈单元的断口及对应的两第一末端的位置。依据这些第一末端的位置而决定导电结构的分布方式，其中导电结构连接这些第一末端，以使这些线圈单元通过导电结构而构成连续的线路，其中导电结构具有一对输入电极，输入电极适于连接外界的电流，使电流依序通过这些线圈单元而在各线圈单元形成磁场，电流以顺时针方向通过各线圈单元或以逆时针方向通过各线圈单元，以使形成于这些线圈单元的等效垂直于第一图案化导电层的磁场极性方向相同。
在本发明的一实施例中，上述的决定导电结构的分布方式的步骤包括：依据这些第一末端的位置而决定第二图案化导电层及多个第一导电通孔的分布方式，其中这些第一末端分别通过这些第一导电通孔而连接第二图案化导电层。其中第二图案化导电层包括所述输入电极。
在本发明的一实施例中，上述的决定第二图案化导电层的分布方式的步骤包括：依据这些第一末端的位置而决定彼此断开的多个第一导电区段的位置，其中各第一导电区段具有相对的两第二末端，这些第二末端分别对位于这些第一末端且分别通过这些第一导电通孔而连接这些第一末端。
在本发明的一实施例中，上述的决定导电结构的分布方式的步骤包括：依据这些第一末端的位置而决定部分第二图案化导电层、部分第三图案化导电层及多个第一导电通孔的分布方式，其中部分这些第一末端分别通过部分这些第一导电通孔而连接部分第二图案化导电层，部分这些第一末端通过部分这些第一导电通孔而连接部分第三图案化导电层。依据部分第二图案化导电层的分布方式而决定部分第三图案化导电层及多个第二导电通孔的分布方式，其中部分第三图案化导电层通过这些第二导电通孔而连接部分第二图案化导电层，第三图案化导电层包括所述输入电极。

基于上述，在本发明的阵列式无线能量转换装置中，这些线圈单元以几何中心不相同的方式分布于单层结构(第一图案化导电层)中，而非如同传统线圈的多匝线圈单元依序叠设或以单层同心圆的方式分布。因此，这些线圈单元经过适当的排列分布，可使得这些线圈单元所产生的充电磁场在垂直于第一图案化导电层的方向，可充分地相叠加而增加充电磁场的分布高度。进一步而言，依据线圈单元的形状来决定这些线圈单元的排列方式，使各线圈单元的至少一个边相邻且平行于另一线圈单元的一个边，可让这些线圈单元的位置尽可能地集中，以有效提升这些线圈单元所产生的充电磁场的叠加效果，据以增加无线充电装置的有效充电距离。此外，用以串联这些线圈单元的导电结构是配置于第一图案化线路层的下方，而非与这些线圈单元位于同一层，故可避免导电结构过度干扰这些线圈单元所产生的充电磁场。

具体实施方式
图1是本发明一实施例的阵列式无线能量转换装置的侧视示意图。图2 是图1的阵列式无线能量转换装置的部分结构俯视图，用以示出第一图案化导电层的配置方式。请参考图1及图2，本实施例的阵列式无线能量转换装置100包括第一图案化导电层110及导电结构120。第一图案化导电层110包括几何中心不相同的多个线圈单元112，其中这些线圈单元112非为几何中心相同结构，且各线圈单元112位于其他各线圈单元112之外。各线圈单元112为多边形(示出为正六边形)，且这些线圈单元112以尽可能集中的方式排列，使各线圈单元112的至少一个边L(示出为多个边L)相邻于另一线圈单元112的一个边L。这些线圈单元112可依需求而为适当数量，本发明不对此加以限制。
各线圈单元112具有断口112a及对应于断口112a的两第一末端E1。导电结构120配置于第一图案化导电层110下方且连接这些第一末端E1，以使这些线圈单元112通过导电结构120而构成连续的线路。导电结构120具有一对输入电极124b(示出于图5)，输入电极124b适于连接外界的电流。从而，可使电流依序通过这些线圈单元112而在各线圈单元112形成充电磁场，其中电流以顺时针方向通过各线圈单元112或以逆时针方向通过各线圈单元112，以使形成于这些线圈单元112的等效垂直于第一图案化导电层110的磁场极性方向相同。使用者可将电子装置50置于阵列式无线能量转换装置100的上方，使电子装置50通过所述充电磁场进行充电。
在上述配置方式之下，这些线圈单元112分布于单层结构(第一图案化导电层110)中，而非如同传统线圈以呈同心圆的多匝线圈单元沿垂直于充电平面方向依序叠设，而是通过调整阵列中基本线圈单元112间的排列方式，来增加无线充电装置100的有效充电距离。进一步而言，依据线圈单元112的形状(示出为六边形)来决定这些线圈单元112的排列方式，使各线圈单元112的至少一个边相邻于另一线圈单元的一个边，可让这些线圈单元112的位置尽可能地集中，以有效提升这些线圈单元112所产生的充电磁场的叠加效果，据以增加无线充电装置100的有效充电距离(以图1所示的垂直方向V而言)。此外，用以串联这些线圈单元112的导电结构120是配置于第一图案化线路层110的下方，而非与这些线圈单元112位于同一层，故可避免导电结构120过度干扰这些线圈单元112所产生的充电磁场。
图3是图2的阵列式无线能量转换装置的局部放大图。请参考图3，具 体而言，各线圈单元112具有几何中心C及半径R，半径R是几何中心C至边L的最短距离。如上述般以尽可能集中的方式来排列这些线圈单元112，以使相邻的两线圈单元112的两几何中心C的距离D大于半径R的两倍且小于半径R的二分之五倍。在其他实施例中，相邻的两线圈单元112的两几何中心C的距离D与半径R可为其他适当关系，本发明不对此加以限制。
在本实施例中，第一图案化导电层110及导电结构120例如是形成于介电材料130中。以下通过图4至图6详细说明本实施例的导电结构120的具体配置方式。图4至图6是图1的阵列式无线能量转换装置的部分结构俯视图，其中图4用以示出导电结构120的第二图案化导电层122的配置方式，图5用以示出导电结构120的第三图案化导电层124的配置方式，图6用以示出第一图案化导电层110、第二图案化导电层122及第三图案化导电层124的相对位置。
如图1、图2及图4至图6所示，本实施例的导电结构120包括第二图案化导电层122、多个第一导电通孔T1、第三图案化导电层124及多个第二导电通孔T2。第二图案化导电层122包括彼此断开的多个第一导电区段122a，各第一导电区段122a具有相对的两第二末端E2，部分这些第二末端E2分别对位于部分这些第一末端E1，部分这些第二末端E2分别对位于部分这些第三末端E3。第三图案化导电层124包括彼此断开的多个第二导电区段124a，各第二导电区段124a具有相对的两第三末端E3。第一图案化导电层110的部分这些第一末端E1分别通过部分这些第一导电通孔T1而连接第二图案化导电层122的部分这些第二末端E2，且部分这些第一末端E1通过部分这些第一导电通孔T1(如图6所标示的邻近中央的输入电极124b的第一导电通孔T1)而连接第三图案化导电层124的部分这些第二末端E2。第三图案化导电层124的部分第三末端E3分别通过这些第二导电通孔T2而连接第二图案化导电层122的部分第二末端E2。第三图案化导电层124还包括所述输入电极124b，用以输入充电电流。
如图6所示，第二图案化导电层122的各第一导电区段122a至少部分地沿第一图案化导电层110的这些线圈单元112的延伸方向延伸，以避免第二图案化导电层122过度干扰这些线圈单元112所产生的充电磁场。此外，第三图案化导电层124配置于第二图案化导电层122下方而远离第一图案化导 电层110，以避免第三图案化导电层124过度干扰这些线圈单元112所产生的充电磁场。
图7A示出传统多匝线圈单元所共同产生的磁场。图7B示出图1的这些线圈单元所共同产生的磁场。图7C示出图1的这些线圈单元的间距增加后所共同产生的磁场。若在真空中有存在稳态电流的细导线，其中的电流为常数I，此细导线在空间中形如单连封闭曲线C，则依据必欧-沙伐定律(Biot-Savart Law)，整个细导线上的电流对导线外位置P所造成的磁场为
Figure PCTCN2017085994-appb-000001
其中rrel为dl'与P的距离，
Figure PCTCN2017085994-appb-000002
为dl'向P的单位向量。依据必欧-沙伐定律进行数值模拟可获得图7A所示传统多匝线圈单元所共同产生的磁场，图7B所示的图1的这些线圈单元112所共同产生的磁场，及图7C所示图1的这些线圈单元112的间距增加后所共同产生的磁场。相较于单一线圈单元所产生的磁场(对应于图7A)及间距较大的多个线圈单元所共同产生的磁场(对应于图7C)，图1的这些线圈单元112所共同产生的磁场(对应于图7B)，其磁力线在垂直方向V上较为多且集中，可达到在垂直方向上增加有效充电距离的显著效果。
图8是本发明另一实施例的阵列式无线能量转换装置的侧视示意图。图9是图8的阵列式无线能量转换装置的部分结构俯视图，用以示出第二图案化导电层的配置方式。在图8及图9的阵列式无线能量转换装置200中，第一图案化导电层210及介电材料230的配置方式类似前述实施例的第一图案化导电层110及介电材料130的配置方式，于此不再赘述。阵列式无线能量转换装置200与阵列式无线能量转换装置100的不同处在于，阵列式无线能量转换装置200将图1及图5所示的第三图案化导电层124整合图4所示的第二图案化导电层122而形成图9所示的第二图案化导电层222，导电结构220包括第二图案化导电层222及第一导电通孔T1，第一图案化导电层210的这些第一末端E1分别对位于第二图案化导电层222的这些第二末端E2，第一图案化导电层210的这些第一末端E1分别通过这些第一导电通孔T1而连接第二图案化导电层222的这些第二末端E2，且第二图案化导电层222包括一对输入电极224b。藉此，可简化阵列式无线能量转换装置200的制程。
图10是本发明另一实施例的阵列式无线能量转换装置的部分结构俯视图，用以示出第一图案化导电层的配置方式。在图10所示实施例中，第一图案化导电层310及介电材料330的配置方式类似图2所示实施例的第一图案化导电层110及介电材料130的配置方式，于此不再赘述。图10所示实施例 与图2所示实施例的不同处在于，阵列式无线能量转换装置还包括多个导磁性材料M，这些导磁性材料M分别配置于这些线圈单元312内，以增强各导磁性材料M产生的磁场。
以下通过附图说明本发明一实施例的阵列式无线能量转换装置的设计方法。图11是本发明一实施例的阵列式无线能量转换装置的设计方法流程图。请参考图1、图2及图11，首先，决定线圈单元112的形状(步骤S602)。接着，依据线圈单元112的形状而决定几何中心不相同的多个线圈单元112的排列方式，以使各线圈单元112的至少一个边L相邻于另一线圈单元112的一个边L，其中这些线圈单元112构成第一图案化导电层110(步骤S604)。依据这些线圈单元112的排列方式而决定各线圈单元112的断口112a及对应的两第一末端E1的位置(步骤S606)。依据这些第一末端E1的位置而决定导电结构120的分布方式，其中导电结构120连接这些第一末端E1，以使这些线圈单元112通过导电结构120而构成连续的线路，其中导电结构120具有一对输入电极124b，输入电极124b适于连接外界的电流，使电流依序通过这些线圈单元112而在各线圈单元112形成磁场，电流以顺时针方向通过各线圈单元112或以逆时针方向通过各线圈单元112，以使形成于这些线圈单元112的等效垂直于第一图案化导电层110的磁场极性方向相同(步骤S608)。
在上述步骤S602中，除了可将线圈单元112的形状决定为图2所示的六边形，也可将其决定为其他形状，举例说明如下。图12A至图12E示出本发明其他实施例的线圈单元的形状，其将线圈单元示出为尚未形成断口。在图12A至图12E所示实施例中，线圈单元412、512、612、712、812的形状分别被决定成三边形、四边形、五边形、八边形、九边形，并以尽可能集中的方式排列。
请参考图2、图8及图9，在上述步骤S608中，决定导电结构220的分布方式的步骤包括：依据这些第一末端E1的位置而决定第二图案化导电层222及多个第一导电通孔T1的分布方式，其中这些第一末端E1分别通过这些第一导电通孔T1而连接第二图案化导电层222。其中这些第二图案化导电层222包括所述输入电极224b。
承上，决定第二图案化导电层222的分布方式的步骤包括：依据这些第一末端E1的位置而决定彼此断开的多个第一导电区段222a的位置，其中各 第一导电区段222a具有相对的两第二末端E2，这些第二末端E2分别对位于这些第一末端E1且分别通过这些第一导电通孔T1而连接这些第一末端E1。
请参考图1、图2、图4、图5及图6，在上述步骤S608中，决定导电结构120的分布方式的步骤包括：依据这些第一末端E1的位置而决定部分第二图案化导电层122、部分第三图案化导电层124及多个第一导电通孔T1的分布方式，其中部分这些第一末端E1分别通过部分这些第一导电通孔T1而连接部分第二图案化导电层122，且部分这些第一末端E1通过部分这些第一导电通孔T1(如图6所标示的邻近中央的输入电极124b的第一导电通孔T1)而连接部分第三图案化导电层124。此外，在上述步骤S608中，决定导电结构120的分布方式的步骤还包括：依据部分第二图案化导电层122的分布方式而决定部分第三图案化导电层124及多个第二导电通孔T2的分布方式，其中部分第三图案化导电层124通过这些第二导电通孔T2而连接部分第二图案化导电层122。其中这些第三图案化导电层124包括所述输入电极124b。
承上，决定第二图案化导电层122的分布方式的步骤包括：依据部分这些第一末端E1的位置和这些第二导电通孔T2的位置而决定彼此断开的多个第一导电区段122a的位置，其中各第一导电区段122a具有相对的两第二末端E2，部分这些第二末端E2分别对位于部分这些第一末端E1且分别通过部分这些第一导电通孔T1而连接部分这些第一末端E1。部分这些第二末端E2分别对位于这些第二导电通孔T2而连接部分第三图案化导电层124。
承上，决定这些第一导电区段122a的位置的步骤包括：依据这些线圈单元112的延伸方向而决定各第一导电区段122a的延伸方向，其中各第一导电区段122a至少部分地沿这些线圈单元112的延伸方向延伸。
承上，决定第三图案化导电层124的分布方式的步骤包括：依据部分第二图案化导电层122的分布方式和部分第一图案化导电层110的分布方式而决定彼此断开的多个第二导电区段124a的位置，其中各第二导电区段124a具有相对的两第三末端E3，部分这些第三末端E3分别通过这些第二导电通孔T2而连接部分第二图案化导电层122，且部分这些第三末端E3通过部分这些第一导电通孔T1(如图6所标示的邻近中央的输入电极124b的第一导电通孔T1)而连接第一图案化导电层110。
请参考图10，上述的阵列式无线能量转换装置的设计方法还可包括以下 步骤：依据这些线圈单元312的位置而决定多个导磁性材料M的位置，其中这些导磁性材料M分别配置于这些线圈单元312内。
综上所述，在本发明的阵列式无线能量转换装置中，这些线圈单元以几何中心不相同的方式分布于单层结构(第一图案化导电层)中，而非如同传统线圈以呈同心圆的的多匝线圈单元依序叠设。因此，这些线圈单元经过适当的排列分布，可使得这些线圈单元所产生的充电磁场在垂直于第一图案化导电层的方向，可充分地相叠加而增加充电磁场的分布高度。进一步而言，依据线圈单元的形状来决定这些线圈单元的排列方式，使各线圈单元的至少一个边相邻于另一线圈单元的一个边，可让这些线圈单元的位置尽可能地集中，以有效提升这些线圈单元所产生的充电磁场的叠加效果，据以增加无线充电装置的有效充电距离。此外，用以串联这些线圈单元的导电结构是配置于第一图案化线路层的下方，而非与这些线圈单元位于同一层，故可避免导电结构过度干扰这些线圈单元所产生的充电磁场。
虽然本发明已以实施例揭示如上，然其并非用以限定本发明，任何所属技术领域中技术人员，在不脱离本发明的精神和范围内，当可作些许的更动与润饰，故本发明的保护范围当视权利要求所界定者为准。
