The three contacts on the side of the X907 body are wireless charging connection points, which can be realized through a specific charging protective case; There is a receiving circuit in the charging protective case, which is connected with the three contacts of the mobile phone for charging. Wireless charging principle is completed by electromagnetic induction, X907 mobile phone hardware itself is no induction circuit, is through the charging protective cover (receive) and charging base (emission) cooperationTo finish.
Wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, etc. Wireless charging of mobile phones mostly uses the principle of electromagnetic induction. Electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger's power supply coil) will generate a magnetic field, other unenergized coil (mobile phone side of the electric coil) close to the magnetic field will generate current, charging the mobile phone.
Mobile phone wireless charging is achieved through the use of wireless charging technology, mainly in the following ways: Qi wireless charging: Qi is a wireless charging standard, veryMultiple phones and chargers support the standard. Wireless charging can be achieved simply by placing the phone on a charger or wireless charging dock that supports the Qi standard.
The fourth: electric field coupling wireless charging, this charging method is a vertical way through the two asymmetric dipoles to generate current transmission, this charging method conversion rate is very high, the position of the two can also not be fixed, but there is a big disadvantage, that is, the need for equipment larger volume, power is particularly small.
Electromagnetic induction The most common way of wireless charging is to use the principle of electromagnetic induction,The basic principle of wireless charging is to convert the current into a magnetic field, which is transmitted through the air and then converted into a current to be transmitted to the intelligent terminal. When the system works, the input end converts the AC mains into direct current through the full bridge rectifier circuit, or uses the 24V direct current end to supply power to the system directly. After passing through the power management module, the output direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding.
Radio energy transmission for wireless power transmission, non-contact power transmission, through the transmitter to convert electrical energy into other forms of relay energy (such as electromagnetic field energy, laser, microwave and mechanical waves, etc.), air transmissionAfter a certain distance, the relay energy is converted into electrical energy through the receiver to achieve radio energy transmission.
1, the steps are as follows: first, cut the end of the USB data cable connected to the phone with scissors or a knife, and then cut a short section of the long end of the data cable into the incision, at this time you will see four green, red, white and black lines, cut the green and black two, and cut the red and green two respectivelySmall sections of insulation exposed copper wire.
2, open the back cover of the smartphone, and then take out the wireless charging receiver ready; Or the protective layer of double-sided tape peel; The next task is to connect the receiver's metal shock to the smartphone battery, which is the most difficult part of the process. However, as long as you are careful to ensure that each metal shock is connected together, it can be done.
3, there are two coils on the wireless charger and the mobile phone, when the wireless charger coil is connected to the power supply, the coil plus alternating current will produce a changing magnetic field, put the mobile phone in chargeWhen on the board, the coil on the back cover of the mobile phone will sense the change of the magnetic field, and the coil on the back cover of the mobile phone will sense the current, and then the current is converted into direct current to charge our mobile phone battery, so as to achieve wireless charging.
4, one of the self-wound coil connected in the charging circuit, 555 output foot (third foot) with an output tube (at your own will, but to high frequency power tube) output tube link self-wound coil, will be connected to the two coils close (about 1 cm or so there is a very sufficient charging current) power can be wireless charged! This circuit is very inefficient because it onlyThere are half peaks and high frequencies, so the loss is relatively large, but the principle is quite simple and easy to produce.
5, question 1: How to make wireless charger? There are many ways to use wireless chargers, mainly to see how the reception is installed. But no matter what the product is close, the operation method is placed on the launch plate. Take the mobile phone for example, the current mobile phone is generally added a mobile phone jacket, in this jacket there is a wireless receiver module. The phone can be charged wirelessly with this jacket.
6, is the use of the principle of electromagnetic induction, if you can do it yourselfA vibration circuit, the vibration signal is added to a coil, the other coil string an LED, the two coils close to the light. If you want to produce your own, you can go to Xincotec, there are very cheap modules. You can also buy IC processing. It's cheap to make.

Mobile phone wireless charging refers to the meaning that the charger and the electrical device can be connected to the phone without wires.
Wireless charging is also known as inductive charging, non-contact inductive charging to create wireless charging , from wireless power transmission technology, is the use of near-field induction,That is, inductive coupling, in which the power supply device (charger) transmits energy to the electrical device, which uses the received energy to charge the battery and at the same time for its own operation.Wireless charging, also known as inductive charging, non-contact inductive charging, is the use of near-field induction, that is, inductive coupling, by the power supply device (charger) to transmit energy to the device that uses electricity. If the distance between the charger and the electrical device is far, it is necessary to use resonant inductive coupling design.
Wireless charger refers to the charger that is not connected to the terminal device that needs to be charged without the traditional charging power cord.Using to create wireless charging The latest wireless charging technology, by using the magnetic field generated between the coils, the magic transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment.
To answer this question, we need to start from the development of wireless charging and its principlesSpeak of it. In the 1830s, Michael Faraday discovered that changes in the surrounding magnetic field would create an electric current in the wire. In the 1890s, Nikola Tesla, an assistant to Edison's spectral radiation research project, proposed the idea of wireless power transmission.
Solar charging At present, solar charging is a common way of charging. Many car dolls rely on solar energy to charge their heads. Therefore, this technology is expected to be applied to car driving in the future to ensure that the car can be charged when driving under a certain amount of light. But if there's bad weather, maybeCan hinder vehicle charging and driving problems.
When the car is driving on the road equipped with wireless charging coils, through the principle of electromagnetic induction, electrical energy can be transmitted wirelessly to the car battery, so as to achieve the effect of charging while driving. However, this scheme faces problems such as high construction costs and difficult maintenance. Solar charging technology Solar charging technology is an environmentally friendly and renewable way to use energy.
