The invention provides electronic equipment and a wireless charging system. The electronic equipment comprises a support member and an induction coil assembly arranged on the support member, wherein the induction coil assembly comprises an induction coil and a first annular positioning assembly surrounding the periphery of the induction coil, the first annular positioning assembly comprises a first annular soft magnetic bottom plate and a first annular magnetic steel assembly stacked with the first annular soft magnetic bottom plate, the first annular magnetic steel assembly comprises first annular magnetic steel, second annular magnetic steel and third annular magnetic steel, the first annular magnetic steel, the second annular magnetic steel and the third annular magnetic steel are sequentially arranged from inside to outside in the radial direction, the first annular magnetic steel and the third annular magnetic steel are magnetized in the axial direction, the polarity of the side,facing the first annular soft magnetic bottom plate, of the first annular magnetic steel is opposite to the polarity of the side, facing the first annular soft magnetic bottom plate, of the third annular magnetic steel, and the second annular magnetic steel is magnetized in the radial direction. According to the electronic equipment provided by the invention, the magnetic attraction force and theelectromagnetic shielding effect of the first annular positioning assembly can be effectively improved.
Description
【Technical field】 [0001] The invention relates to the field of wireless charging, in particular to electronic equipment and a wireless charging system. 【Background technique】 [0002] In the existing wireless charging system, a first magnetic positioning component is provided on the electronic device, a second magnetic positioning component is provided on the wireless charging device, and the magnetic connection between the first magnetic positioning component and the second magnetic positioning component passes between the electronic device and the wireless charging device. The suction realizes the automatic alignment between the transmitting coil and the induction coil to improve the charging efficiency, and realizes electromagnetic shielding through the magnetic positioning component to avoid electromagnetic influence on the electronic components inside and outside the magnetic positioning component. However, due to structural limitations, the first magnetic positioning c...
