Description
本發明係屬於無線充電設備之技術領域，特別是關於一種可撓式無線充電板，以便於使用者捲折後收納而利於隨身攜帶。 The invention belongs to the technical field of wireless charging devices, in particular to a flexible wireless charging board, which is convenient for the user to carry around after being folded and stored.
自無線充電技術襲起一陣熱潮後，具有無線充電功能的電子裝置及可供電子裝置進行無線充電的充電裝置等應用亦隨之常見於市場販售上，而該充電裝置1之組成架構可如圖1所示由一第一基板10、一第一磁導體11、一第二基板12、一第一絕緣膜13、一感應線圈14、一第二絕緣膜15、一第二磁導體16及一電源器(圖未示)所構成。該感應線圈14、該第一絕緣膜13、該第二基板12及該第一磁導體11係由上而下依序疊置於該第一基板10上，且該感應線圈14由銅線反覆纏繞而略呈楕圓狀之框體設置，以供該第二絕緣膜15置於該感應線圈14中央框圈內後承置該第二磁導體16。又，該感應線圈14電性連接該電源器，以透過該電源器取得工作電流後電磁感應該第一磁導體11及該第二磁導體16而透過磁耦共振原理提供該電子裝置充電電流。如此，使用者無需使用連接線即可進行電子裝置的充電作業，著實方便操作，促使相關應用產品具有可觀的銷售市場。也因此，各廠商為爭取更具優勢的銷售競爭力，無不紛紛提出各式改良原始無線充電設備的創作概念，如台灣新型專利M453229及M455965係藉具有黏性的包覆層或基板中混合導磁材料而簡化該充電裝置1之製程步驟及提升整體感應線圈的耦合效率與導磁效率，或台灣新型專利M454618為改善裝置於製造、搬運或使用過程中因受外力彎折而破裂的情況發生，係使該等基板10、12及該等絕緣膜13、15利用可撓性材料製成， 以些微增加裝置整體的彈性度而降低產品損耗率。 Since the wireless charging technology has caused a wave of enthusiasm, applications such as electronic devices with wireless charging function and charging devices for wireless charging of electronic devices are also commonly sold in the market, and the composition of the charging device 1 can be as 1 shows a first substrate 10, a first magnetic conductor 11, a second substrate 12, a first insulating film 13, an inductive coil 14, a second insulating film 15, a second magnetic conductor 16 and A power supply (not shown) is formed. The induction coil 14, the first insulating film 13, the second substrate 12, and the first magnetic conductor 11 are sequentially stacked on the first substrate 10 from top to bottom, and the induction coil 14 is repeatedly covered by copper wires. The winding and slightly rounded frame is disposed for the second insulating film 15 to be placed in the central frame of the induction coil 14 to receive the second magnetic conductor 16. Moreover, the induction coil 14 is electrically connected to the power source to obtain an operating current through the power source, and then electromagnetically senses the first magnetic conductor 11 and the second magnetic conductor 16 to provide the charging current of the electronic device through a magnetic coupling resonance principle. In this way, the user can perform the charging operation of the electronic device without using the connection line, which is convenient and convenient for operation, and promotes a considerable sales market for related application products. Therefore, in order to strive for more advantageous sales competitiveness, all manufacturers have proposed various innovative original wireless charging devices. For example, Taiwan's new patents M453229 and M455965 are mixed with a viscous coating or substrate. The magnetic material simplifies the manufacturing process of the charging device 1 and improves the coupling efficiency and magnetic permeability of the overall induction coil, or the new Taiwan patent M454618 is used to improve the device to be broken due to bending by external force during manufacturing, handling or use. The occurrence of the substrates 10, 12 and the insulating films 13, 15 is made of a flexible material. The product loss rate is reduced by slightly increasing the overall elasticity of the device.
由前述可知，該充電裝置1係具一定程度的感應面積而不利 於使用者收納或攜帶使用，即使如M454618專利提出利用可撓性基板取代習知硬式印刷電路板的方式，該充電裝置1仍因受該等磁導體11、16的結構及材料特性限制而無法進行大幅度的彎折。為此，習知提出台灣發明專利201143251 A1，供允許無線充電技術應用窄型感應面傳送能量，以改善裝置因體積過大而不易收納的問題。但，此種透過縮小感應面而實現易於收納或攜帶功能的改良方式雖仍可磁感應生成充電電流，但受磁感面積的限制，故明顯地具有充電效能低落的缺失，而不甚實用且不利於產品滿意度。 It can be seen from the foregoing that the charging device 1 has a certain degree of sensing area and is disadvantageous. The user can store or carry it in, even if the M454618 patent proposes to replace the conventional rigid printed circuit board with a flexible substrate, the charging device 1 cannot be limited by the structure and material properties of the magnetic conductors 11, 16. Make a big bend. To this end, Xizhi proposed the Taiwan invention patent 201143251 A1, which allows the wireless charging technology to apply a narrow sensing surface to transmit energy, so as to improve the problem that the device is too large to be easily stored. However, such an improved method of reducing the sensing surface to achieve an easy storage or carrying function can magnetically generate a charging current, but is limited by the magnetic sensing area, so that there is a clear lack of charging performance, which is not practical and disadvantageous. Product satisfaction.
有感於此，如何使該充電裝置1具有最大感應面積的條件 下，改良裝置結構而使其具有捲折功能，以允許使用者透過多次層疊的方式收捲無線充電板而縮小整體體積，達便於收納及隨身攜加之功效，即為本發明所亟欲解決之問題。 In view of this, how to make the charging device 1 have the maximum sensing area Next, the structure of the device is modified to have a crimping function, so as to allow the user to wind up the wireless charging board by multiple stacking to reduce the overall volume, so as to facilitate the storage and carry-on effect, which is intended to solve the problem of the present invention. The problem.
