Wireless thinking (Think for wireless)

Wireless charger Choose car wireless charger or portable wireless charger?

1, convenient: compared with ordinary mobile phone charger, mobile phone wireless charger belongs to one-to-many charging, which solves the connectionThe problem of the mouth is not applicable, but also to avoid the phenomenon of poor contact caused by repeated plugging and removing of the mobile phone interface, which can better protect the mobile phone interface, and the elderly can also easily use it. Safety: Mobile phone wireless charger has a variety of protection functions, such as: overcharge and overdischarge, metal foreign body detection and other functions, always protect the safety of users.

2, if the mobile phone does not support, like Apple, Huawei mobile phone can be. You need to connect a wireless charging patch on your phone. At present, the car charger basically uses the QI protocol wireless charging standard, and the mobile phone and the car charger that meet this protocol can be matched for charging. thereforeAs long as the transmitter and receiver are QI certified, they can basically be charged. The charger that is not suitable for the power of the phone will damage the battery of the phone.

3, this Huawei CP39S wireless charger is a car wireless charger, suitable for driving mobile phone users. Wireless charging supports 27W fast charge, but it only supports Huawei's own mobile phone that supports FCP fast charge.

4, according to Baidu Encyclopedia, wireless charging of mobile phone charging is actually low-power wireless charging, that is, electromagnetic induction charging, and wireless charging in the car is actually electromagnetic induction wireless charging in the carCharge up. The principle of wireless charging is electromagnetic induction, which is usually used in small power situations and does not require electrode contact points. There are induction coils in the small column and electricity, there are induction coils in the electric toothbrush insertion part, and there are plastic insulation outside, there is no electrical contact, and the induction obtains electricity to charge the battery and drive the small motor.

Wireless charging principle - electromagnetic induction wireless charging Electromagnetic induction wireless charging is the most used wireless charging solution, high school physics textbooks have mentioned through the primary coil a certain frequency of alternating current, using electromagneticInduction generates a certain current in the secondary coil, which transfers energy from the transmission end to the receiving end.

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.

Now there are many electric toothbrushes using wireless charging technology, the principle of this technologyIn fact, it is the law of electromagnetic induction, that is, a magnetic field is set around the current, and an electric field is generated by changing the magnetic field to achieve the effect of charging, which is similar to the principle of induction cookers.

The wireless charger contains a copper transmitting coil. When the electric toothbrush is placed on the charger, the transmitter coil generates an electromagnetic field, which the receiver converts into electrical energy from the electric toothbrush battery. This process is called electromagnetic induction. Because the copper receiver and transmitter coils are small, wireless charging can only be charged at close range. Whether electric toothbrush wireless charging can be universal depends on the protocol used by electric toothbrushes.

What are the important characteristics of innovative thinking

1, innovative thinking is different from the general procedural logic thinking, its main characteristics are novelty, flexibility, artistry, exploration. The answer to this question is ABCD.

2. ABCD. Analysis: Innovative thinking is different from the general procedural logic thinking, the characteristics of innovative thinking include: novelty, flexibility, artistry, exploration. The answer to this question is ABCD.

3, the characteristics of innovative thinking are divided into the following points: uniquenessInnovative thinking is a unique way of thinking that emphasizes taking innovation as a starting point in the thinking process and pursuing novelty and uniqueness. Innovative thinking emphasizes breaking the traditional mode of thinking and looking at and solving problems with new perspectives and methods. This way of thinking is irreplaceable and unique.
