Mi Matter wireless charging mouse pad disassemble Use a crowbar to separate the mouse pad. Divided into aluminum base and mouse pad two parts. The mouse pad is hollowed out above the corresponding wireless charging part to reduce thickness and maintain consistency. The wireless charging circuit board and coil are attached to the aluminum base plate. Compare the size of a $1 coin. The back of the magnetic separator is insulated with high-temperature tape, the PCB capacitor position is hollowed out to reduce the thickness, and the back has no components. Wireless charging part, the circuit board is more concise.
Compared with the 10000mAh wireless charging treasure currently on sale, the youth version is in the appearanceThe calculation is basically the same, but the new black and white color choice is more young and fashionable. The shell material is changed from metal to plastic, and the function is slightly reduced, so the price is reduced by 20 yuan.
Xiaomi Wireless charging treasure youth version 10000mAh disassembly Xiaomi wireless charging treasure uses an integrated plastic shell, which can only be violently disassembled. Open the shell of the wireless charging surface, inside is the wireless charging coil and thermistor, and there is a shielding cover on the circuit board above. Remove the wireless charging coil to expose the battery. The battery adopts Lishen 7V battery, 10Ah, 10000mAh capacity, the highest charging voltage 2V. batteryThere is a thermistor on the side to detect the battery temperature in real time.
1, and for the iPhone 12 series, it provides magnetic-assisted positioning, the mouse pad has a circle of magnets. The magnetic force is a bit weaker than the magsafe charger, but it's perfectly sufficient to assist with positioning, and other phone series can use location stickers. 2, from the theory, wireless charging technology is safe and harmless to the human body, the resonance principle used by wireless charging is magnetic field resonance, only at the same frequencyResonance is transmitted between coils, and other devices cannot accept the band, in addition, wireless charging technology uses the magnetic field itself is harmless to the human body. The wireless charger looks like a plastic mouse pad, the "mouse pad" is equipped with a dense array of small coils, so it can generate a magnetic field, and transmit energy to the electronic device equipped with a special receiving coil, so as to charge. The receiver coil is made of magnetic alloy wound around wire and is similar in size and shape to chewing gum, so it can be easily attached to electronic devices.
4I don't know what type, but I think it works the same way. From a macro point of view, I use a dual fly G3100 wireless package, I have taken apart the mouse, it is a pulley, micro switch, optical controls and circuit board, there are no magnets. Of course, from a microscopic point of view, as long as there is electricity, there will be magnetism, but the small is almost negligible.
5, wireless charging technology uses magnetic resonance in the electric field and magnetic field between the charger and the device to transmit electrical energy, coil and capacitor form resonance between the charger and the device. This system could be widely used in the future, for example in charging zones for electric vehiclesAnd power transfer to computer chips.
6, the mouse pad corresponds to the wireless charging part of the upper hollow, reduce the thickness, maintain consistency. The wireless charging circuit board and coil are attached to the aluminum base plate. Compare the size of a $1 coin. The back of the magnetic separator is insulated with high-temperature tape, the PCB capacitor position is hollowed out to reduce the thickness, and the back has no components. Wireless charging part, the circuit board is more concise. Giga Device MCU GD32F350K8U6 64K FLASH 8K SRAM. Microcontroller detailed parameters.
