用于无线充电装置的感应线圈结构
摘要：
本发明公开了一种感应线圈结构，用于一无线充电装置，所述感应线圈结构包括至少一第一线圈，设置在一感应线圈的第一层；至少一第二线圈，设置在所述感应线圈的第二层；一第一磁导体，位于所述至少一第一线圈与所述至少一第二线圈之间，其中，所述第一磁导体的第一面叠合所述至少一第一线圈，第二面叠合所述至少一第二线圈；以及一第二磁导体，叠合在所述至少一第二线圈中的一第二线圈上未叠合所述第一磁导体的一面。所述第一磁导体包括一开孔，而用来绕制所述至少一第一线圈中的一第一线圈的一导线从第一层通过所述开孔而延伸至第二层，以绕制所述至少一第二线圈中的一第二线圈。通过上述感应线圈结构，可提升无线充电装置的效率。
摘要（英）：

An induction coil structure for a wireless charging device includes at least one first coil, disposed in a first layer of an induction coil; at least one second coil, disposed in a second layer of the induction coil; a first magnetic conductor, located between the first coil and the second coil, wherein a first surface of the first magnetic conductor is superposed on the first coil and a second surface of the first magnetic conductor is superposed on the second coil; and a second magnetic conductor, superposed on a surface that is not superposed on the first magnetic conductor of one of the second coil. The first magnetic conductor includes a hole, and a wire for winding one of the at least one first coil extends from the first layer to the second layer via the hole, to wind one of the at least one second coil. In this way, efficiency of wireless charging device can be increased.
