Magnetic absorption of the magnetic shell. The middle of the mobile phone case is embedded with a small ring holding wireless charging magnetic ring, which can improve the wireless charging effect of the mobile phone, and the magnetic force is as high as 10N, which perfectly matches the wireless charging ring of the charging device.
Connect the phone's standard charger and data cable to the wireless charger, and then put the phone directly (vertically) or horizontally at the bottom of the wireless chargerThe center position of the left and right seat can realize wireless charging, the indicator light will have a breathing effect, and it will be extinguished after 5 seconds, plug and play, convenient and quick.
Connect the standard charger and data cable of the mobile phone to the wireless charger, and then put the mobile phone directly (vertically) or horizontally in the center position of the wireless charger base, you can realize wireless charging, the indicator light will have a breathing effect, 5 seconds later, plug and play, convenient and quick. two.
Turning on the vivox80's wireless charging feature is very simple. The first step is to connect the charging pad to a power outlet. Then, place the charging pad on a flat surface and make sureMake sure there's nothing blocking it. Next, pull down the notification bar in your vivox80 phone, and you'll see a charging icon. Click the charging icon, then select the "Wireless Charging" option. At this point, your phone will automatically connect to the charging pad and start charging.
Unlike the conventional way of connecting the power cord to the phone to charge, it only needs to put the phone directly on the charging table to charge. As shown in Figure 1, "The coil of the charger (power output side) is flowingThe magnetic flux is generated by alternating current, and the magnetic flux is connected to the coil of the smartphone (power receiving side) and passes through the induced current. Using this principle of electromagnetic induction to charge.
The answer lies in the Pixel 5's unique design. Although the whole body is made of aluminum, Google has cleverly cut a gap inside the body to house the "ultra-thin bio-resin skin." This bioresin layer, which is actually an extremely thin and strong plastic, cleverly acts as a bridge between the aluminum and the wireless charging coil, ensuring smooth transmission of electrical signals.
The second is the magnetic resonance, whichIt also consists of a transmitting device and a receiving device combined. A frequency between the two devices needs to be tuned to the same stage, because only then can they resonate. But there is no way to commercialize this technology. In May, Qualcomm announced that it had completed a trial of wireless charging for electric vehicles on the road, that is, adding inductive charging devices on the road, so that the car can be charged while driving. Unlike most inductive charging, Qualcomm Halo technology provides high energy transmission across space and is suitable for a variety of vehicle types. It has a multi-coil design, even if the charging pad is not aligned with the vehicleIt can carry out efficient energy transfer.
Convenient: no need to connect with a wire when charging, as long as it is placed near the charger, there is no need to occupy multiple power sockets, there is no trouble of multiple wires winding each other. The disadvantages of wireless charging are slightly lower in efficiency: the general charger also has a transformer, but the wireless charging transformer composed of the transmitting coil and the receiving coil is limited in structure, and the energy transmission efficiency is theoretically slightly lower than that of the general charger. Toyota has announced that it will begin testing its vehicle wireless charging technology in Japan, which can charge pure electric vehicles and plug-in hybrid electric vehicles in the futureThe pool is fully charged in 90 minutes. The principle of this technology is to use the electromagnetic field generated by the charging coil for wireless charging. Toyota's charging coils are arranged in ground-level parking Spaces. When the car is parked in a parking space, the charging receiver located in the chassis of the car receives electrical energy from the charging coil to start charging.
1, mobile phone space charging technology is to install the transmitter coil on the wireless charging base, install the receiving coil on the back of the mobile phone, when the mobile phone is near the charging base to chargeWhen the transmitting coil is connected to an alternating current, an alternating magnetic field is generated. The change in the magnetic field generates an induced current in the receiving coil, which transfers energy from the transmitting end to the receiving end, and finally completes the charging process. 2, in simple terms, the wireless charger is actually a charging mode that relies on the energy of electromagnetic waves to convert electromagnetic waves into electrical energy. 3, there is still a lot of space for the development of wireless charging technology, electromagnetic induction is only one of them, in addition to magnetic resonance and other theoretical technology support of the space charging, interested in you can understand. One last note, if you're using a wireless chargerElectricity, be sure not to put the bus card with the chip, bank card, etc. near the wireless charger, it may be degaussed, bringing unnecessary trouble.
4, the realization of air separation charging technology requires a close cooperation between the mobile phone and the charging device. First, the charging device needs to accurately identify the location and charging needs of the phone to adjust the frequency and strength of the magnetic field. Second, the mobile phone needs a built-in efficient receiving coil and charge management chip to ensure that the magnetic field energy can be quickly received and stably converted into electricity.
5, mobile phone space charging device is a wireless charge that meets the requirements of ROHSThe shooting scheme adopts low-frequency magnetic resonance wireless charging technology, which greatly improves the charging distance, and the furthest charging distance can reach 35mm, easily realizing the convenience brought by wireless. The application of this solution can realize the wireless charging transmitter products placed on the desktop (non-metal or magnetic conductive material) below, mobile phones, laptops and other Qi standard equipment placed on the desktop, can be wireless charging/power supply.
6, complete the mobile phone charging process. The wireless charger connected to the power supply excludes the patented technology to control the size of the current and magnetic flux parameters, which is essentially a pile of wires that are regularly tangled together. In its access 220VDuring the household alternating current, a closed loop will be formed, and the magnetic field will be generated in the closed loop because of the action of alternating current, and the magnetic flux of the magnetic field will change accordingly, which can be understood as the magnetic force will change.
