S 5 201214915 藉由此交變磁通，於二次側線圈模組35產生與上述頻率相 同頻率的感應電力。藉由此感應電力，所產生的交流電流 係整流成為直流電流，將其直流電流供給至二次電池3 6， 以對於二次電池36充電《基於二次電池36成為充滿電的 狀態，充電裝置2係停止對行動電話〗的充電。 參照圖2與圖3，說明二次側線圈模組35的構成。 如圖2所示，二次侧線圈模組35係包含平面狀的第一 線圈41，以及配設其的導磁板4〇。導磁板4〇係由軟磁性 的亞鐵鹽粉末燒結而形成。 第一線圈41係將導線環狀捲繞而形成。第一線圈41 的中央設有中空空間之空心部45。 配置第一線圈41的導磁板40係包含俯視時形成圓環 狀的平面部42。如圖2所示，平面部42的内周緣係設有 具圓柱狀外形的内侧突起部43，其係從平面部42向上側， 即向：次侧線圈模組u (參照圖n突出。平面部42的外 周緣係設有圓筒狀的外侧突起部44，其係從平面部42向 上，，即向一次側線圈模組11 (參照圖1)突出。内侧突 P 43與外側突起部44係相對於平面部垂直地突出。 如圖3所示’内侧突起部4 3形成剖面形狀呈上側開口 办側凹^的凹部47。又，平面部42的厚部T1與内側 從复P的厚度T2係相等。另外，外側突起部44係設有 部4、4下端部向外側延伸的圓環狀的延伸部46。此外側突起 ° 4的厚度Τ3與平面部4;3的厚度T1係相等。 第一線圈41安裝於導磁板4〇的狀態下，内側突起部 201214915 =#41^部45。此時，内側突起部43的外周面係與 係盘第始靠近。另外，外側突起部44的内周面 =;:Γ的外周靠近。換言之，外側突起部44的 44的肉闲、第—線圈41的外周緣接觸，或者，外側突起部 44及第=與第一線圈41的外周緣係僅間隔外侧突起部

在此說明一次側線圈模組n與二次側線圈模組％ 間形成的磁路。 一次側線圈模組U與二次侧線圈模組35靠近的狀熊 下，供給交流電流至第二線圈51時，形成以下的磁路。 ^圖3所示’所形成的磁路係從第二線圈51的内周側向第 一線圈41的内周側，經由導磁板40，從第一線圈41的外 周側向第二線圈51的外周側，再經由導磁板50回到第二 線圈51的内周側。又，依據第二線圈Μ的電流的方向7 會形成與上述磁路成為反向的磁通流動的磁路。亦即，一 次側線圈模組11與二次測線圈模組35之間，基於供給至 201214915 一次側線圈模組u的交流電流，交 與此磁路成為反向的磁通流動的磁路細成上述磁路以及 如此，第二線圈51 且朝向内側突起部43。此時側突， 55的磁通係通過内側突起部53 一51的空心部 =並且’從内側突起部53流出的磁通成為 另外，一次侧線圈模組U的磁通到達二次側線圈模电

(1)藉由於導磁板40設置外側突起部44，可減少朝 向較二次側線圈模組35外侧流動的漏磁通的量。 再者，藉由於導磁板40設置内侧突起部43，磁通從 二次側線圈模組35朝向一次側線圈模組U的情況時，朝 向第一線圈41的空心部45流動的磁通係從内側突起部43 朝向一次侧線圈模組u流動。因此，可減少兩線圈模組 11 3 5之間的漏磁通的量。 另外，一次側線圈模組11亦相同地設有内側突起部 53及外側突起部54。因此，兩線圈模組11、35之間的磁 201214915 通分別於内側突起部43、53之間及外側突起部44、54間 流動。因此’可更減少兩線圈模組11、35之間的漏磁通的 量。 (2) 如圖8所示，二次側線圈模組35的構成可舉例 如於平板狀地成形的導磁板300安裝空心線圈31〇，將導 磁板300較空心線圈310外側的外側部32〇曲折後安裝於 殼體34。若依據如此的構成，相較於圖7所示的構成，可 減少漏磁通的量。 但因上述外側部320隨著朝向上側而向徑向外侧傾 斜’因此’來自上述外側部32〇的磁通朝向一次側線圈模 組11 (參照圖3)流動時，磁通係沿著上述外側部32〇流 動而有磁通向外側擴散的可能。其結果，減少向兩線圈模 組11、35的外側流動的漏磁通之效果降低。又，將圖8的 構成適用於一次側線圈模組21亦會產生相同的問題。 關於此點’第-實施型態中，外側突起部44係相對於 平面部42垂直地突出的形狀，因此，相較於圖8所示的構 成，從外側突起部44流動的磁通係朝向垂直下側流動（參 照圖3)。因此’相較於圖8所示的構成，可減少兩線圈模 組Π、35之間的漏磁通的量。 (3) 一次線圈模組35係内藏於電池組％。因此，可 提高充電裝置2對於電池組33 @二次電池36的充電效率。 另外於一久側線圈模組35與一次侧線圈模組n之 間進行電壓信號的送受信的情況時，因兩線圈模組η、35 之間的漏磁通的里少，gj此可更適當地進行電壓信號的送 201214915 受信。 I、 （4)外側突起部44係設有延伸部46。因此，相較於 省略延伸部46的外側突起部，磁通從-次侧線圈模組u 向二次線圈模組35流動時，增大接受從外側突起部54向 外側突起部44流動的磁通的面積。因此，可更減少兩線圈 模組11、35之間的漏磁通的量。另外，磁通從二次側線圈 松組35向-次側線圈模組n流動時，藉由外侧突起部Μ 的延伸部S6即可獲得與外側突起部44的延伸部46所產生 之相同的效果。 (第二實施型態） 參照圖4,說明本發明的第二實施型態。第二實施型 態中，相較於第-實施型態，詳細朗相異的部分，且於 相同構成標記相同符號，省略其說明。 、 第一實施型態中，導磁板40的平面部42的厚度η

若依據第二實施型態，除了第一實施型態的效果（1) 〜（3)以外，可產生以下的效果。 (5)内側突起部63係藉由局部增大導磁板6〇的厚度 ，形成。因此，相較於第一實施型態的内側突起部43，可 藉由内側突起部63使從空心線圈61向空心部65流動的磁 通量增加。因此，可更減少兩線圈模組u、35間的漏磁通 的量。 (6)外侧突起部64係藉由局部增大導磁板60的厚度 而形成。因此，相較於如同内側突起部43 一般的設有凹部 的構成，可使k過外側突起部64的磁通量增加。因此，可 201214915 更減少兩線圈模組11、35間的漏磁通的量。 (其他的實施型態） 本發明的非接觸傳送電力線圈模組以及具備其的電池 組的具體構成並未限定於上述各實施型態的内容，例如， 可為以下的變化。另外，以下的變化例並非僅適用於上述 各實施型態，而亦可互相組合相異的變化例來實施。 第一實施型態中，如圖5

Therefore, the number of the corresponding portion is marked with a number of five heads, and the description thereof is omitted. The outer dimension of the inner protrusion M3 of the magnetic conductive plate 4 () is larger than the outer dimension of the inner protrusion portion μ of the magnetic conductive plate %. Here, the magnetic field formed between the primary side coil module n and the secondary side coil module % is described. When the primary side coil module U and the secondary side coil module 35 are close to each other and supply an alternating current to the second coil 51, the following magnetic circuit is formed. ^ The magnetic circuit system formed in Fig. 3 From the inner peripheral side of the second coil 51 toward the inner peripheral side of the first coil 41, from the outer side of the first coil 41 via the magnetic conductive plate 40 The circumferential side faces the outer peripheral side of the second coil 51 and returns to the inner peripheral side of the second coil 51 via the magnetic conductive plate 50. Further, the direction 7 of the current according to the second coil turns is reversed from the magnetic path described above. The magnetic circuit through which the magnetic flux flows, that is, between the primary side coil module 11 and the secondary measuring coil module 35, based on the alternating current supplied to the primary winding module u of 201214915, the magnetic circuit is reversed. The magnetic path through which the magnetic flux flows is made into the magnetic circuit and thus, the second coil 51 and toward the inner protrusion 43. At this time, the magnetic flux of the side protrusion 55 passes through the hollow portion of the inner protrusion 53-51 and is 'from the inside The magnetic flux flowing out of the protruding portion 53 is different, and the magnetic flux of the primary side coil module U reaches the secondary side coil mode. When the magnetic flux passes through the flat portion via the inner protruding portion 43, the outer protruding portion 44 The first coil 5 is oriented toward the first line ll * 1 (four). At this time, the outer protruding portion 44 ′′ is reduced to the amount of leakage magnetic flux outside the second measuring coil module 35 . Further, the magnetic flux from the outer protruding portion 44 toward the second coil 51 is directed toward the outer protruding portion 54' of the magnetic conductive member 5', so that the magnetic flux leakage toward the outer side of the two coil modules u, % > The amount is reduced. According to the first embodiment, the following effects can be produced. (1) By providing the outer protrusion portion 44 to the magnetic conductive plate 40, the amount of leakage magnetic flux flowing toward the outer side of the secondary side coil module 35 can be reduced. Further, when the magnetic flux is provided from the secondary side coil module 35 toward the primary side coil module U by the inner side protrusion portion 43 of the magnetic conductive plate 40, the magnetic flux flowing toward the hollow portion 45 of the first coil 41 The inner protruding portion 43 flows toward the primary side coil module u. Therefore, the amount of leakage flux between the two coil modules 11 3 5 can be reduced. Further, the primary side coil module 11 is also provided with the inner protruding portion 53 and the outer protruding portion 54 in the same manner. Therefore, the magnetic current 201214915 between the two coil modules 11 and 35 flows between the inner protrusions 43, 53 and between the outer protrusions 44 and 54, respectively. Therefore, the amount of leakage flux between the two coil modules 11, 35 can be further reduced. (2) As shown in FIG. 8, the secondary side coil module 35 is configured such that the core coil 31 is formed in a flat plate shape, and the core coil 31 is attached, and the outer side of the outer side of the hollow coil 310 is provided. The 32 turns are attached to the casing 34 after being bent. According to such a configuration, the amount of leakage magnetic flux can be reduced as compared with the configuration shown in Fig. 7 . However, since the outer side portion 320 is inclined outward in the radial direction as it goes toward the upper side, the magnetic flux from the outer side portion 32〇 flows toward the primary side coil module 11 (see FIG. 3), and the magnetic flux is along the outer side. The portion 32 〇 flows and there is a possibility that the magnetic flux diffuses to the outside. As a result, the effect of reducing the leakage magnetic flux flowing to the outside of the two coil modules 11 and 35 is reduced. Further, the same problem arises when the configuration of Fig. 8 is applied to the primary side coil module 21. In this point, in the first embodiment, the outer protruding portion 44 has a shape that protrudes perpendicularly to the flat portion 42. Therefore, the magnetic flux flowing from the outer protruding portion 44 is oriented as compared with the configuration shown in FIG. Flows vertically downward (see Figure 3). Therefore, the amount of leakage magnetic flux between the two coil modules Π, 35 can be reduced as compared with the configuration shown in Fig. 8. (3) The primary coil module 35 is housed in the battery pack %. Therefore, the charging efficiency of the charging device 2 with respect to the battery pack 33 @ secondary battery 36 can be improved. When the voltage signal is transmitted and received between the one-side coil module 35 and the primary coil module n, the leakage flux between the two coil modules η and 35 is small, and gj can be more appropriately Send the voltage signal 201214915 Trusted. I. (4) The outer protruding portion 44 is provided with an extending portion 46. Therefore, when the magnetic flux flows from the secondary-side coil module u to the secondary coil module 35, the magnetic flux that receives the flow from the outer projection 54 to the outer projection 44 is increased as compared with the outer projection of the extension 46. The area of the passage. Therefore, the amount of leakage magnetic flux between the two coil modules 11, 35 can be further reduced. Further, when the magnetic flux flows from the secondary side coil loose group 35 to the secondary side coil module n, the same as that of the extending portion 46 of the outer protruding portion 44 can be obtained by the extending portion S6 of the outer protruding portion 的. effect.

In other words, the portion of the hollow portion 65 of the two coils 61 is formed toward the (four) and the innermost portion 62 is increased. Therefore, the thickness H1 of the inner protrusion 3 is thicker than the thick part τ1 of the flat portion 62. Further, the thickness H3 of the inner protrusion 63 is thicker than the thick portion n of the flat portion 62. The outer protrusion portion 64 has a cross-sectional shape that is a protrusion shape that protrudes from the bottom surface (four) of the magnetic conductive plate (9). In other words, the outer protruding portion 64 is formed such that the outer peripheral edge of the flat portion 62 is thicker than the portion where the air-core coil 61 is disposed in the same plane portion 62. Therefore, the thickness m of the outer protrusion portion 64 is thicker than the thickness portion τι of the plane portion. Further, the thickness H4 of the outer protruding portion 64 is thicker than the thick portion T1 of the flat portion 62. According to the second embodiment, in addition to the effects (1) to (3) of the first embodiment, the following effects can be produced. (5) The inner protrusion portion 63 is formed by locally increasing the thickness of the magnetic conductive plate 6A. Therefore, the amount of magnetic flux flowing from the air-core coil 61 to the hollow portion 65 can be increased by the inner protruding portion 63 as compared with the inner protruding portion 43 of the first embodiment. Therefore, the amount of leakage magnetic flux between the two coil modules u and 35 can be further reduced. (6) The outer protrusion portion 64 is formed by locally increasing the thickness of the magnetic conductive plate 60. Therefore, the magnetic flux of the k-outer protrusion portion 64 can be increased as compared with the configuration in which the recess portion is provided as the inner protrusion portion 43. Therefore, the amount of leakage flux between the two coil modules 11 and 35 can be further reduced by 201214915.
