The invention discloses a transmitting assembly for wireless charging of an electric automobile. The transmitting assembly comprises a non-metal shell, a transmitting coil, a transmitting magnetic core and a metal shell that are sequentially assembled from top to bottom. The transmitting magnetic core comprises at least two ferrite layers which are stacked in a staggered mode. Each ferrite layer is formed by splicing a plurality of ferrites; the ferrite layer corresponding to the periphery of the transmitting coil is close to the transmitting coil; the rest ferrite layers are sequentially arranged in a retracting manner corresponding to the central position of the transmitting coil and are gradually far away from transmitting coil. The invention further discloses a charging assembly for wireless charging of the electric automobile, wherein the charging assembly comprises the transmitting assembly and the receiving assembly which are arranged in parallel, the problem that a transmittingmagnetic field is uneven in distribution is solved, magnetic saturation is inhibited, and the wireless charging efficiency is improved.
本发明公开了一种电动汽车无线充电的发射组件,包括自上而下依次组装的非金属外壳、发射线圈、发射磁芯和金属壳体,发射磁芯包括至少2层交错堆叠的铁氧体层,每层铁氧体层均由若干铁氧体拼接而成,其中对应发射线圈的外围的铁氧体层靠近发射线圈,其余铁氧体层对应发射线圈的中心位置依次缩进设置,且逐渐远离发射线圈,所有铁氧体层堆叠拼接的形状在平面的投影对应发射线圈的形状,本发明还公开了一种电动汽车无线充电的充电组件,包括平行设置的发射组件和接收组件,解决了发射磁场分布不均匀的问题,抑制磁饱和,提高了无线充电效率。
