Title:
ELECTRONIC DEVICE AND WIRELESS CHARGING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/104915
Kind Code:
A1
Abstract:
An electronic device (10), comprising a support (12) and an induction coil assembly (11) provided on the support (12), wherein the induction coil assembly (11) comprises an induction coil (111) and a first annular positioning assembly (112) surrounding the periphery of the induction coil (111), the first annular positioning assembly (112) comprises first annular magnetic steel (1121), second annular magnetic steel (1122), an annular soft magnet (1123), third annular magnetic steel (1124) and fourth annular magnetic steel (1125); the first annular magnetic steel (1121), the second annular magnetic steel (1122), the annular soft magnet (1123), the third annular magnetic steel (1124) and the fourth annular magnetic steel (1125) are sequentially arranged from inside to outside in the radial direction. The first annular magnetic steel (1121) and the fourth annular magnetic steel (1125) are magnetized in the axial direction, and the polarity of the side of the first annular magnetic steel (1121) facing towards the support (12) is opposite to the polarity of the side of the fourth annular magnetic steel (1125) facing towards the support (12), and the second annular magnetic steel (1122) and the third annular magnetic steel (1124) are magnetized in the radial direction, and the polarities of the opposite sides of the second annular magnetic steel (1122) and the third annular magnetic steel (1124) are opposite to each other. The electronic device (10) can effectively improve the magnetic attraction and electromagnetic shielding effect of the first annular positioning assembly (112). The present invention also relates to a wireless charging system (100).
