Description

由多個磁導體組成之磁導體結構Magnetic conductor structure composed of multiple magnetic conductors

本發明係指一種磁導體結構，尤指一種由多個磁導體所組成之磁導體結構。The present invention relates to a magnetic conductor structure, and more particularly to a magnetic conductor structure composed of a plurality of magnetic conductors.

感應式電源供應器係藉由線圈進行振盪來發送電磁能量，以傳送無線電力。一般來說，受電裝置或物體會放置在供電線圈之一感應面，以從供電線圈接收無線電力。然而，當供電線圈振盪時，能量會向四面八方發送，但只有朝向感應面發送之部分能量可傳達至受電裝置，而造成充電效率低落。為解決上述問題，業界普遍採用設置磁導體的方式，將磁導體設置於供電線圈之非感應面，以利用磁性材料反射線圈之能量，使得線圈發送之多數能量能夠傳達至受電裝置，進而提高充電效率。An inductive power supply sends electromagnetic energy by oscillating a coil to transmit wireless power. Generally, a power receiving device or object is placed on one of the induction surfaces of the power supply coil to receive wireless power from the power supply coil. However, when the power supply coil oscillates, energy will be sent in all directions, but only part of the energy sent toward the induction surface can be transmitted to the power receiving device, resulting in low charging efficiency. In order to solve the above problems, the industry generally adopts a magnetic conductor method. The magnetic conductor is provided on the non-inductive surface of the power supply coil, so that the magnetic material reflects the energy of the coil, so that most of the energy sent by the coil can be transmitted to the power receiving device, thereby improving charging. effectiveness.

然而，一般磁導體的製作方式是由磁粉燒結而成，其結構十分脆弱且易碎。當磁導體用於線圈能量反射時，需設計大面積的片狀磁導體，然而，其易碎的特性造成大面積片狀磁導體之生產良率降低。有鑑於此，習知技術實有改進之必要。However, the general magnetic conductor is made by sintering magnetic powder, and its structure is very fragile and fragile. When a magnetic conductor is used for coil energy reflection, a large-area chip magnetic conductor needs to be designed. However, its fragile characteristics cause a reduction in the production yield of a large-area chip magnetic conductor. In view of this, it is necessary to improve the conventional technology.

因此，本發明之主要目的即在於提供一種磁導體結構，其可透過多個磁導體所組成，而不需使用單片大面積磁導體，同時達到良好的線圈包覆性。Therefore, the main object of the present invention is to provide a magnetic conductor structure that can be composed of multiple magnetic conductors without using a single large-area magnetic conductor, and at the same time achieve good coil coverage.

本發明揭露一種磁導體結構，用於一線圈模組，該線圈模組包含有一線圈，該磁導體結構包含有一底層磁導體、一內磁導體及一外磁導體。該底層磁導體設置於該線圈之一面，該底層磁導體係由複數個第一磁導體組合而成。該內磁導體設置於該線圈之內側，該內磁導體係由複數個第二磁導體組合而成。該外磁導體設置於該線圈之外側，該外磁導體係由複數個第三磁導體組合而成。The invention discloses a magnetic conductor structure for a coil module. The coil module includes a coil. The magnetic conductor structure includes a bottom magnetic conductor, an inner magnetic conductor, and an outer magnetic conductor. The bottom magnetic conductor is disposed on one side of the coil, and the bottom magnetic conductor system is composed of a plurality of first magnetic conductors. The inner magnetic conductor is disposed inside the coil, and the inner magnetic conductor system is formed by combining a plurality of second magnetic conductors. The outer magnetic conductor is disposed outside the coil, and the outer magnetic conductor system is composed of a plurality of third magnetic conductors.

請參考第1A圖及第1B圖，第1A圖及第1B圖為本發明實施例一線圈模組10之示意圖。其中，第1A圖繪示線圈模組10之正面，第1B圖繪示線圈模組10之背面。如第1A圖所示，線圈模組10包含有一線圈100、一底層磁導體102、一內磁導體104及一外磁導體106。在此例中，由於線圈100之正面為用來發送能量之感應面，因此底層磁導體102可設置於線圈100之背面。在此情形下，線圈100向背面發射的能量可藉由底層磁導體102的反射，回傳至位於感應面的受電裝置。進一步地，由於線圈振盪時能量會向四面八方發送，因此，亦可在線圈100內側及外側分別設置內磁導體104及外磁導體106；其中，內磁導體104可貼合於線圈100內側，且外磁導體106可貼合於線圈100外側。在此情形下，原先向四周發散的能量也能夠集結而傳送至位於感應面的受電裝置，可大幅提升線圈模組10之供電效率。線圈模組10所採用的底層磁導體102、內磁導體104及外磁導體106可由具有高導磁率特性之磁性材料所構成。磁性材料可為一錳鋅磁芯（Mn-Zn Core）、鎳鋅磁芯（Ni-Zn Core）、鐵粉芯（Iron Powder Core）、鐵鎳鉬磁芯（Molypermalloy Powder （MPP） Core）、鐵矽鋁磁芯（Sendust Core）、鐵氧體磁芯（Ferrite Core）、高磁通磁芯（High Flux Core）或其它等效之磁性材料。此外，不同位置之磁導體可採用相同或不同的磁性材料，端視系統需求而定，且不應以此為限。Please refer to FIG. 1A and FIG. 1B, which are schematic diagrams of a coil module 10 according to an embodiment of the present invention. Among them, FIG. 1A shows the front of the coil module 10, and FIG. 1B shows the back of the coil module 10. As shown in FIG. 1A, the coil module 10 includes a coil 100, a bottom magnetic conductor 102, an inner magnetic conductor 104, and an outer magnetic conductor 106. In this example, since the front surface of the coil 100 is an induction surface for transmitting energy, the bottom magnetic conductor 102 may be disposed on the back surface of the coil 100. In this case, the energy emitted by the coil 100 to the back can be reflected back to the power receiving device on the induction surface by the reflection of the underlying magnetic conductor 102. Further, since the energy is transmitted in all directions when the coil oscillates, the inner magnetic conductor 104 and the outer magnetic conductor 106 may be provided on the inside and outside of the coil 100, respectively, wherein the inner magnetic conductor 104 may be attached to the inside of the coil 100, and The outer magnetic conductor 106 may be attached to the outside of the coil 100. In this case, the energy originally radiated to the surroundings can also be gathered and transmitted to the power receiving device located on the induction surface, which can greatly improve the power supply efficiency of the coil module 10. The bottom magnetic conductor 102, the inner magnetic conductor 104, and the outer magnetic conductor 106 used by the coil module 10 may be formed of a magnetic material having high magnetic permeability characteristics. The magnetic material can be a Mn-Zn Core, a Ni-Zn Core, an Iron Powder Core, a Molypermalloy Powder (MPP) Core, Sendust Core, Ferrite Core, High Flux Core, or other equivalent magnetic materials. In addition, the magnetic conductors at different locations can use the same or different magnetic materials, depending on the system requirements, and should not be limited to this.

一般來說，為有效包覆線圈100，底層磁導體102、內磁導體104及外磁導體106較佳地可設計為片狀磁導體。底層磁導體102需要較大面積，以同時將線圈100、內磁導體104及外磁導體106貼合在底層磁導體102上。此外，內磁導體104及外磁導體106的高度可設計為與線圈100之高度相同，使得線圈100、內磁導體104及外磁導體106可完全對齊，以實現良好的線圈包覆性。Generally, to effectively cover the coil 100, the bottom magnetic conductor 102, the inner magnetic conductor 104, and the outer magnetic conductor 106 are preferably designed as sheet-shaped magnetic conductors. The bottom magnetic conductor 102 needs a large area to attach the coil 100, the inner magnetic conductor 104, and the outer magnetic conductor 106 to the bottom magnetic conductor 102 at the same time. In addition, the height of the inner magnetic conductor 104 and the outer magnetic conductor 106 can be designed to be the same as the height of the coil 100, so that the coil 100, the inner magnetic conductor 104, and the outer magnetic conductor 106 can be completely aligned to achieve good coil coverage.

隨著無線充電功率需求的提升，線圈100之表面面積需對應增加，所需磁導體面積也隨之而提升。換言之，線圈模組10中的底層磁導體102、內磁導體104及外磁導體106之面積大小都應隨著線圈100大小而對應調整。然而，如上所述，片狀磁導體結構之面積大且薄，存在易碎和生產良率低的缺點。為解決上述問題，在本發明之線圈模組10中，底層磁導體102、內磁導體104及外磁導體106皆可由多個磁導體分別組合而成，詳述如下。As the demand for wireless charging power increases, the surface area of the coil 100 needs to increase correspondingly, and the required magnetic conductor area also increases accordingly. In other words, the areas of the bottom magnetic conductor 102, the inner magnetic conductor 104, and the outer magnetic conductor 106 in the coil module 10 should be adjusted corresponding to the size of the coil 100. However, as described above, the area of the sheet-shaped magnetic conductor structure is large and thin, and it has the disadvantages of fragility and low production yield. In order to solve the above problems, in the coil module 10 of the present invention, the bottom magnetic conductor 102, the inner magnetic conductor 104, and the outer magnetic conductor 106 can be respectively composed of a plurality of magnetic conductors, as described in detail below.

如第1B圖所示，底層磁導體102為近似正方形之結構，其包含有9個正方形或近似正方形之片狀磁導體，以3×3的排列方式組合成底層磁導體102。在上述結構中，每一單片磁導體之長度及寬度縮減為底層磁導體102之三分之一，可解決習知技術中大面積磁導體生產良率低的缺點。其中，每一片狀磁導體之間可透過任何方式相連，例如透過膠帶黏貼而形成完整的底層磁導體102。在其它實施例中，亦可採用其它連接方式來形成底層磁導體102，磁導體的結合方式不應為本發明之限制。As shown in FIG. 1B, the bottom magnetic conductor 102 has a structure that is approximately square, and includes nine square or nearly square sheet-shaped magnetic conductors, and the bottom magnetic conductor 102 is assembled in a 3 × 3 arrangement. In the above structure, the length and width of each monolithic magnetic conductor is reduced to one third of the bottom magnetic conductor 102, which can solve the shortcoming of the low yield of large-area magnetic conductors in the conventional technology. Among them, each piece of magnetic conductor can be connected by any means, for example, by sticking with an adhesive tape to form a complete bottom magnetic conductor 102. In other embodiments, other connection methods can also be used to form the bottom magnetic conductor 102, and the combination of the magnetic conductors should not be a limitation of the present invention.

值得注意的是，底層磁導體102的形狀可搭配系統需求任意設計，而不限於此。在此例中，底層磁導體102設計為具有小缺角的正方形，以方便設置於正方形的底座或支架上。但在其它實施例中，亦可不設計缺角而形成正方形，或依據線圈形狀而設計為圓形，而不限於此。除此之外，第1B圖所示之3×3排列的片狀磁導體設計方式僅為本發明眾多實施方式當中的一種。實際上，每一底層磁導體可由任意數目的片狀磁導體所組成，較佳地，一底層磁導體可包含N2 個正方形或近似正方形之片狀磁導體，以N×N的排列方式組合而成，其中，N為2以上的正整數。It is worth noting that the shape of the underlying magnetic conductor 102 can be arbitrarily designed with the system requirements, and is not limited to this. In this example, the bottom magnetic conductor 102 is designed as a square with a small notch, so as to be conveniently arranged on a square base or bracket. However, in other embodiments, it is also possible to form a square without designing a notch, or to design a circle according to the shape of the coil, without being limited thereto. In addition, the design method of the 3 × 3 array of sheet-shaped magnetic conductors shown in FIG. 1B is only one of many embodiments of the present invention. In fact, each bottom magnetic conductor can be composed of any number of sheet magnetic conductors. Preferably, a bottom magnetic conductor can include N 2 square or nearly square sheet magnetic conductors, which are combined in an N × N arrangement. , Where N is a positive integer of 2 or more.

同樣地，內磁導體104及外磁導體106亦可由多個較小的磁導體組合而成，以方便生產並提高良率。如第1A圖所示，為使內磁導體104貼合於線圈100之內側，內磁導體104可設計為圓形，其可包含4個扇形之片狀磁導體，其中每一片狀磁導體之圓心角為90度，所有片狀磁導體的頂點相連而組合成內磁導體104。而每一扇形片狀磁導體可透過黏膠貼合而形成內磁導體104，或各別黏貼於底層磁導體102上。另一方面，為使外磁導體106貼合於線圈100之外側，外磁導體106可設計為空心圓形，其可包含12個近似半月形之片狀磁導體，其中每一片狀磁導體之一側邊與另一半月形片狀磁導體之一側邊依序相連而組合成外磁導體106。而每一半月形片狀磁導體可透過黏膠貼合而形成外磁導體106，或各別黏貼於底層磁導體102上。在其它實施例中，亦可採用其它連接方式來形成內磁導體104或外磁導體106，磁導體的結合方式不應為本發明之限制。Similarly, the inner magnetic conductor 104 and the outer magnetic conductor 106 can also be composed of a plurality of smaller magnetic conductors to facilitate production and improve yield. As shown in FIG. 1A, in order to make the inner magnetic conductor 104 fit inside the coil 100, the inner magnetic conductor 104 may be designed to be circular, which may include 4 fan-shaped sheet-shaped magnetic conductors, each of which is a sheet-shaped magnetic conductor. The center angle is 90 degrees, and the apexes of all the sheet-shaped magnetic conductors are connected to form the inner magnetic conductor 104. Each fan-shaped sheet-shaped magnetic conductor can be bonded to form the inner magnetic conductor 104 or adhered to the bottom magnetic conductor 102 respectively. On the other hand, in order to attach the outer magnetic conductor 106 to the outer side of the coil 100, the outer magnetic conductor 106 may be designed as a hollow circle, which may include 12 approximately half-moon shaped magnetic conductors, each of which One side is sequentially connected to one side of the other half-moon-shaped sheet-shaped magnetic conductor to form an outer magnetic conductor 106. Each half-moon-shaped sheet-shaped magnetic conductor can be adhered to form the outer magnetic conductor 106 or adhered to the bottom magnetic conductor 102 respectively. In other embodiments, other connection methods may also be used to form the inner magnetic conductor 104 or the outer magnetic conductor 106, and the combination of the magnetic conductors should not be a limitation of the present invention.

請參考第2圖，第2圖為外磁導體106之一種實現方式之示意圖。由於外磁導體106係由12個近似半月形之片狀磁導體組合而成，每一半月形片狀磁導體的弧度相對應之圓周角為30度，使得12個半月形片狀磁導體恰好可組合成空心圓狀之外磁導體106。在一實施例中，外磁導體106上可包含一開口，用來通過線圈100之導線，如第1A圖所示。舉例來說，可縮短其中一或多個半月形片狀磁導體的長度，以在線圈100之一側形成開口。Please refer to FIG. 2, which is a schematic diagram of an implementation manner of the outer magnetic conductor 106. Since the outer magnetic conductor 106 is composed of 12 pieces of approximately half-moon shaped magnetic conductors, the arc angle corresponding to the arc of each half-moon shaped magnetic conductor is 30 degrees, making the 12 half-moon shaped magnetic conductors exactly It can be combined into a hollow circular outer magnetic conductor 106. In an embodiment, the outer magnetic conductor 106 may include an opening for passing the wire of the coil 100, as shown in FIG. 1A. For example, the length of one or more half-moon-shaped sheet-shaped magnetic conductors can be shortened to form an opening on one side of the coil 100.

值得注意的是，本發明之目的在於提供一種由多個磁導體組合而成的磁導體結構，而不需使用單片大面積磁導體。本領域具通常知識者當可據以進行修飾或變化，而不限於此。舉例來說，在上述實施例中，內磁導體104包含有4個扇形磁導體。但本領域具通常知識者應了解，亦可採用不同數量的扇形磁導體來組成內磁導體104，例如對於面積較大的內磁導體而言，可採用數量更多的扇形磁導體來組成，以避免單片磁導體之面積過大。此外，採用多個扇形磁導體來組成圓形之內磁導體104的方式僅為本發明眾多實施方式當中的一種，在其它實施例中，亦可採用類似底層磁導體102的N×N排列方式來組成內磁導體，或採用2個半圓形磁導體來組成內磁導體。此外，外磁導體106包含有12個半月形磁導體。但在其它實施例中，亦可採用不同數量的半月形磁導體來組成外磁導體106。It is worth noting that the object of the present invention is to provide a magnetic conductor structure composed of a plurality of magnetic conductors, without using a single-piece large-area magnetic conductor. Those skilled in the art can make modifications or changes based on this, without being limited thereto. For example, in the above embodiment, the inner magnetic conductor 104 includes four fan-shaped magnetic conductors. However, those skilled in the art should understand that different numbers of sector magnetic conductors can also be used to form the inner magnetic conductor 104. For example, for inner magnetic conductors with a large area, a larger number of sector magnetic conductors can be used to form, To avoid the area of the monolithic magnetic conductor being too large. In addition, the method of using multiple fan-shaped magnetic conductors to form the circular inner magnetic conductor 104 is only one of many embodiments of the present invention. In other embodiments, an N × N arrangement similar to the underlying magnetic conductor 102 may also be used. To form the inner magnetic conductor, or use 2 semi-circular magnetic conductors to form the inner magnetic conductor. In addition, the outer magnetic conductor 106 includes twelve half-moon-shaped magnetic conductors. However, in other embodiments, different numbers of half-moon magnetic conductors may be used to form the outer magnetic conductor 106.

請參考第3A圖及第3B圖，第3A圖及第3B圖為本發明實施例另一線圈模組30之示意圖。其中，第3A圖繪示線圈模組30之正面，第3B圖繪示線圈模組30之背面。如第3A及3B圖所示，線圈模組30包含有一線圈300、一底層磁導體302、一內磁導體304及一外磁導體306。其中，底層磁導體302、內磁導體304及外磁導體306分別採用與第1A及1B圖中底層磁導體102、內磁導體104及外磁導體106不同之設計方式。Please refer to FIG. 3A and FIG. 3B. FIG. 3A and FIG. 3B are schematic diagrams of another coil module 30 according to an embodiment of the present invention. Among them, FIG. 3A shows the front of the coil module 30, and FIG. 3B shows the back of the coil module 30. As shown in FIGS. 3A and 3B, the coil module 30 includes a coil 300, a bottom magnetic conductor 302, an inner magnetic conductor 304, and an outer magnetic conductor 306. Among them, the bottom magnetic conductor 302, the inner magnetic conductor 304, and the outer magnetic conductor 306 adopt different designs from the bottom magnetic conductor 102, the inner magnetic conductor 104, and the outer magnetic conductor 106 in Figs. 1A and 1B, respectively.

詳細來說，如第3B圖所示，底層磁導體302包含有4個近似正方形之片狀磁導體，以2×2的排列方式組合成底層磁導體302。如第3A圖所示，內磁導體304包含有3個扇形之片狀磁導體，其頂點相連而組合成內磁導體304。在此例中，由於扇形磁導體之數量為3個，每一扇形磁導體之圓心角為120度。外磁導體306則包含有8個近似半月形之片狀磁導體，每一半月形片狀磁導體之一側邊與另一半月形片狀磁導體之一側邊依序相連而組合成外磁導體306。在此例中，由於半月形片狀磁導體之數量為8個，每一半月形片狀磁導體的弧度對應之圓周角為45度。根據第3A及3B圖所示的結構可知，線圈模組之底層磁導體、內磁導體及外磁導體皆可採用多個片狀磁導體組合而成，且片狀磁導體的數量可依實際需求而定，例如可在磁導體面積較大時採用數量更多的片狀磁導體進行組合，以避免單片磁導體之面積過大造成良率降低的缺點。In detail, as shown in FIG. 3B, the bottom magnetic conductor 302 includes four approximately square sheet-shaped magnetic conductors, and the bottom magnetic conductor 302 is assembled in a 2 × 2 arrangement. As shown in FIG. 3A, the inner magnetic conductor 304 includes three fan-shaped sheet-shaped magnetic conductors whose vertices are connected to form the inner magnetic conductor 304. In this example, since the number of sector magnetic conductors is three, the center angle of each sector magnetic conductor is 120 degrees. The outer magnetic conductor 306 includes eight approximately half-moon-shaped sheet-shaped magnetic conductors. One side of each half-moon-shaped sheet magnetic conductor is sequentially connected with one side of the other half-moon-shaped sheet magnetic conductor to form an outer. Magnetic conductor 306. In this example, since the number of half-moon-shaped sheet-shaped magnetic conductors is eight, the arc angle corresponding to the arc of each half-moon-shaped sheet-shaped magnetic conductor is 45 degrees. According to the structure shown in Figs. 3A and 3B, it can be known that the bottom magnetic conductor, the inner magnetic conductor, and the outer magnetic conductor of the coil module can be formed by combining a plurality of sheet-shaped magnetic conductors, and the number of sheet-shaped magnetic conductors can be based on actual conditions. Depending on the requirements, for example, when the area of the magnetic conductor is large, a larger number of chip-shaped magnetic conductors can be combined to avoid the disadvantage that the yield of the single-chip magnetic conductor is too large due to the large area.

綜上所述，本發明提供了用於一線圈模組之磁導體結構，其中，該線圈模組可包含底層磁導體、內磁導體及外磁導體，具有良好的線圈包覆性。同時，在本發明之磁導體結構中，底層磁導體、內磁導體及外磁導體皆可透過任意數量的多個片狀磁導體組成，而不需使用單片大面積磁導體。換言之，本發明之磁導體結構可根據底層磁導體、內磁導體及外磁導體之面積來決定其組成方式，以避免單一片狀磁導體之面積過大，進而提高磁導體之生產良率。 以上所述僅為本發明之較佳實施例，凡依本發明申請專利範圍所做之均等變化與修飾，皆應屬本發明之涵蓋範圍。In summary, the present invention provides a magnetic conductor structure for a coil module.
