China Mobile affiliated companies have applied for the appearance design of wireless charging wireless charging shell design points , according to the text of its description, the purpose of this design product is mainly used for charging electronic devices. According to the description on the document Wireless charge shell designWe can see that its design points are mainly different from the traditional charger in shape, and secondly, it can show that the design concept is to use a wireless way to charge the phone, out of the physical charging.
Electromagnetic induction charging: A certain frequency of alternating current in the primary coil generates a certain current in the secondary coil clock through electromagnetic induction, thereby transferring energy from the transmission end to the receiving end.
According to Apple's patent filing, these connectors, including the iPhone's charging port, could be embedded in the body of the iPhoneThere's no visible opening from the outside. The fewer openings, the less likely it is that your iPhone will be damaged, because without an opening, dust, water, or anything else that might damage the device won't get inside. And it might allow Apple to make the iPhone even thinner.
Jinsheng Precision (300083) : The company has a wireless charging structure related patents, and is developing wireless charging ceramic battery cover technology. Crec (002782) : represented on the interactive platformThere are already wireless charging technology reserves, will actively carry out strategic layout, seize the opportunity to enter the market.
2, advantages: simple to use, the design of the magnetic charging treasure makes the user only need to put the charging treasure close to the mobile phone, you can automatically start charging, without complicated plugging process, which greatly improves the convenience of use. Lightweight and easy to carry, the magnetic charging bank is small in size and light in weight, which is easy for users to carry around, whether it is traveling or daily commuting, it can be easily dealt with.
3, high charging efficiency: magnetic charging technology can achieve fast charging and shorten charging time. Charging method is flexible: users can according to their needsChoose between different charging methods, such as wired or wireless charging. However, the magnetic charging treasure also has some shortcomings: security risks: if the quality of the charging treasure is poor or improper use, there may be overcharge, short circuit and other safety problems.
1, Millet 55W vertical air-cooled wireless charging using PC flame retardant material plastic shell, fuselage edge clear end corner arc transition, support board is black, base sandblasting treatment is gold. From the front, the front end of the base is equipped with LED indicators, and the support board is layered above and below, using different designs. Indicator light is green when working.
2, compared with the common 10W wireless charging technology on the market, Xiaomi's 30W wirelessFlash charge can charge half of the 4000mAh battery in 25 minutes, achieving "wireless beyond wired" efficiency. Xiaomi's vertical air-cooled wireless charge 30W is cleverly designed with an ergonomic tilt, which is convenient for users to operate while charging, and the built-in ultra-quiet fan can effectively actively dissipate heat, improving the comfort of the charging process.
3, millet vertical air-cooled wireless charger (55W black) 199 yuan at present millet maximum power (charging speed is the fastest) wireless charger, if the phone is 30W or 33W wireless charging power, then recommend you"Redundant" buy this high-power wireless charger, because mobile phones upgrade faster, and wireless chargers this product can be used for several years, and a new mobile phone can also achieve power coverage.
2, because of the propagation of energy in the processThe loss is small and the transmission efficiency is high, so as to ensure the normal endurance of the load.
3, but the design of the glass shell rear screen can effectively reduce the loss of energy transmission and reduce the generation of heat, energy can be better transmitted through the communication of the two coils, to ensure that the electronic device will not produce too high heat energy when charging the mobile phone and mobile phone battery damage; And the electrical conductivity of the glass is almost zero, which means that too much heat will not be generated in the process of wireless charging. Signal transmission.
4, Apple is the rear glass is to improve the signal of the device, the metal shell will have a certain signal of the deviceThe impact of... Today's mobile phones have a common appearance, that is, the back cover of the mobile phone is all made of glass design, and from high-end to low-end, many models have adopted this design. Glass has a better signal than other materials, and metal can reflect the signal, causing problems with signal reception.
5, in addition to the glass body has a lot of advantages, such as not easy to occur paint, corrosion and other problems, and tempered glass will not occur after the shell scratch problem, with the development and growth of the glass body, now can be converted into a variety of beautiful colors, to promote the mobile phone shell more and more beautiful.
