Embodiment Construction

[0015] In order to better understand the technical solution of the multi-pole positioning wireless flash charging charger of the present invention, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0016] The transmitter module of the multi-pole positioning wireless flash charging charger is attached image 3 Assembling: the first step: glue the circular transmitting coil (7) on the fixed plate (5-1); the second step is to glue the leak-proof ferrite disc (6) on the circular on the transmitting coil (7); in the third step, one end of the transmitting circuit board (8) is soldered to the transmitting coil (7), and the other end is connected to the input DC5V power line (3) by soldering, and the transmitting circuit board (8) ) is bonded on the top of the leak-proof ferrite disc (6) with glue. The fifth step is to glue the alignment strong magnet piece (9) in the reserved circular hole of the fixing plate (...

Abstract

The invention discloses a multi-magnetic-pole positioning wireless flash charger, and relates to the technical field of wireless charging. The charger is composed of: a transmitting seat upper cover (1); a charger emission seat base (2); an input DC5V power line (3); a USB plug (4); a round pit (5) used for fixing a transmitting module; a transmitting module and receiving module fixing plate (5-1); a magnetic flux leakage prevention ferrite wafer (6); a magnetic flux leakage prevention ferrite wafer (6-1); a circular transmitting coil (7); a circular receiving coil (7-1); a transmitting circuit board (8); an alignment strong magnet sheet (9); a mobile phone rear cover outer plane (10); a round pit (11) used for fixing the receiving module; and a receiving circuit board (12). An even numberof strong magnets with equal radius, equal arc length and different adjacent magnetic poles are arranged around the magnetic flux leakage prevention ferrite wafer; and when a to-be-charged mobile phone is moved to the position above a charging base, the charging base can be attracted to the back face of the mobile phone, the transmitting coil and the receiving coil are accurately aligned, and thecharging efficiency is maximized.

Description

technical field [0001] The invention relates to the technical field of wireless charging, in particular to a multi-magnetic pole positioning wireless flash charging charger. Background technique [0002] A few years ago, Apple shocked the world when it first announced the wireless charger for mobile phones. At that time, sales of Apple mobile phones were booming. When consumers use wireless chargers to charge their mobile phones, a small number of people feel that charging their mobile phones with wireless chargers is as fast as charging them with wired chargers. But for most consumers, charging their mobile phones with a wireless charger has no sense of gain. Think it's too slow to charge with a wireless charger. A wireless charger with a nominal 10 watts is estimated to be only about 2 to 3 watts. The reason is that on the back of the mobile phone, the built-in receiving coil is separated by a mobile phone case with a thickness of several millimeters, and the position ...
