1, is there a wireless charging bank? In 2019, the answer is obviously yes, although there are not many wireless charging products in the real sense on the market, but the overall technology has been relatively mature. The principle of wireless charging treasure is also mainly wireless transmission, eliminating the entangling of wires.
2, wireless charging treasure through wireless charging technology for mobile phones and other equipment power. Easy to use, just handThe back of the machine is placed on the rechargeable side of the wireless charging bank and can be automatically charged. If the mobile phone does not have wireless charging function, you can plug the mobile phone charging port through the attached ring charging sticker, hide the module in the mobile phone case, and place it on the wireless charging bank to charge. Can the wireless charging bank charge the phone while charging? Yes, but not recommended.
3, the principle of wireless charging treasure is to use wireless electromagnetic energy transmission technology to charge mobile devices. This technology enables a mobile device by establishing a radio magnetic field between the wireless charger and the mobile device to transmit electrical energy from the wireless charger to the mobile deviceThe standby device can be charged. Wireless charging bank usually consists of two parts: wireless charger and wireless charging module.
4. Open the phone jacket, plug the receiving module into the charging port, connect the patch to the charging port of the phone, and then put it on, remember to face up. Since the energy is transmitted between the charger and the electrical device by a magnetic field, no wires are connected between the two, so the charger and the electrical device can be exposed without conducting contacts. It is important to note that whether it is a mobile phone or a charging bank, it has a wireless function, that is, a wireless coil.
5, first open the connection on the phoneStable charging experience. Non-metal flexible ultra-thin case: In order to protect your phone and receiving card, it is wise to choose a thin and light case.
2, ensure that the mobile phone supports wireless charging: First, you need to confirm whether your mobile phone supports wireless charging function. You can confirm this by checking the phone's manual or searching for your phone model online. Buy a wireless charger: If your phone supports wireless charging, then the next step is to buy a wireless charger. There are many brands and types of wireless chargers available on the market, and you can choose according to your needs and budget.
3, to add the wireless charging function to the ordinary mobile phone, the most critical is to install a wireless charging receiver. This process usually involves opening the case of the phone, finding where the battery or battery is connected, and welding or connecting the receiver to the appropriate circuit. This requires a certain amount of electronic knowledge and fine manual skills, because the components inside the phone are very small and fragile.
4, mobile phone self-made wireless charging method: there are two specific methods, the first is: use the external module installation, the second is: use the built-in module installation, then the following is a detailed introduction to the installation method, interested users canLet's find out. Mobile phone self-made wireless charging specific steps: self-made wireless charger 1: External module installation steps Stick the module away from the MicroUSB interface comparison place. 5, the mobile phone does not have the function of the method is as follows: you can buy a mobile phone case that supports wireless charging, and install it on the mobile phone, the advantage of this method is simple and convenient, there is no need to replace the mobile phone or remove the internal phone, the disadvantage is that it may increase the weight and thickness of the mobile phone, as well as affect the heat dissipation and signal of the mobile phone.
6. First you need these things: an iPhone's wireless charging receptionCard. A compatible charger. A non-metal flexible ultra-thin casing.
The steps are as follows: First cut the end of the USB data cable connected to the mobile phone with scissors or a knife, and then cut a short section of the long end of the data cable into the incision, you will see four green, red, white and black wires, cut the green and black two, and cut a small section of the insulation layer of the red and green two, respectively, to expose the copper wire.
1. The precautions for winding coils with wireless charging coils mainly include the selection of coils with different frequency characteristics, the selection of magnetic cores of different materials, and the consideration of parameters such as inductance and distributed capacitance of coils. In the wireless charging receiving coil, according to its working characteristics in the audio segment, silicon steel sheet or permalloy is usually selected as the core material.
2, ultra-thin multi-strand and winding coil for the receiving end, the use of multiple copper wire side-by-side winding, effectively reduce the skin effect, so that ultra-thinDesign, improve efficiency. As a key component, magnetic plates, including nanocrystalline magnetic plates and ferrite magnetic plates, are made by rapid solidification, heat treatment, lamination, split and die cutting, respectively, to meet different application needs. 3, wireless charger design takes into account the safety factor, the use of overvoltage protection, overcurrent protection, short circuit protection and other multiple protection mechanisms to ensure the safety of equipment and users during the charging process. Although the wireless charger brings convenience and beauty, it is still necessary to pay attention to the following points when using: Charging efficiency is not due to the transmission mode of the wireless chargerSame as wired charging, charging efficiency may be affected.
4, first of all, according to the needs of the circuit, select the winding method: First of all, determine the size of the inner diameter. Then according to the inductance value and resistance and other factors to determine the coil layer number, height, outside diameter and so on. Wireless charging coil is suitable for short wave, medium wave circuit, its Q value can reach 150-250, and has high stability.
The introduction of the picture of how to do the wireless charging coil and the picture of how to do the wireless charging coil is over, do not know that you find the information you need from it?
