The present invention discloses a wireless charging receiving end structure which comprises a chassis, a coil winding, a tiled magnetic core and a shell which are sequentially arranged from bottom to top, and further comprises an annular magnetic core with the inner wall attached to the peripheral side of the tiled magnetic core, and the annular magnetic core is used for reducing magnetic resistance between a wireless charging receiving end and a wireless charging transmitting end. Compared with the prior art, a circle of annular magnetic core is additionally arranged on the peripheral side of the tiled magnetic core, so that the coverage area of the magnetic core relative to the coil winding is increased, the magnetic resistance between the transmitting end and the receiving end is reduced, and the transmission capacity is improved.
本发明公开了一种无线充电接收端结构,包括从下至上依次设置的底盘、线圈绕组、平铺磁芯、外壳,还包括内壁与所述平铺磁芯的周侧相互贴合的环状磁芯,所述环状磁芯用于降低无线充电接收端与无线充电发射端之间的磁阻。与现有技术相比,本发明通过在平铺磁芯的周侧增加一圈环状磁芯,增大了磁芯相对于线圈绕组的覆盖面积,使发射端与接收端之间的磁阻减小,提高了传输能力。
