Description
Technical field
The utility model belongs to technical field of electronic products, relates in particular to a kind of contact Mobile phone wireless charging device.
Background technology
Current vehicle carried mobile phone support, does not provide power supply mostly.If mobile phone will soon cause mobile phone electric weight not enough in the long-time use of navigation mode when driving.
For this situation, also there are some producers to have different solutions, the most a kind ofly below support, are accompanied with exactly a charge power supply line, after mobile phone is fixed on support, again charging wire is inserted to mobile phone.This method charging is reliable, but in use shows slightly inconvenience.
Another kind of solution is exactly to use the wireless charging technology in current forward position, wireless charging technology (Wireless charging technology; Wireless charge technology).Wireless charging technology, comes from wireless power conveying technology.Wireless charging, is called again induction charging, non-contact inductive charging, is to utilize near field induction, inductance coupling high namely, by power supply unit (charger), transmitted its energy to the device of electricity consumption, this device is used the energy receiving to charge to battery, and simultaneously for itself running.
Wireless charging technology has the following advantages:
1, safety: without wet contact design, can avoid the danger of getting an electric shock.
2, durable: electric power conveying element, therefore can be by erosions such as airborne moisture content, oxygen without exposing; Contactless existence, also so not has the loss of making connecting mechanical wear when separated and arcing etc.
Make medical implant apparatus safer: implanting on embedded medical treatment device, can under not damage systemic situation, to the medical treatment device being implanted in human body, charge and pass skin and other autologous tissues, the risk of removing infection from without the need for electric wire.
3, convenient: during charging without connecting with electric wire, as long as be put near charger.Technical, a charger can enter electricity to a plurality of power devices, the trouble that can save a plurality of chargers in the situation that having a plurality of power device, need not take a plurality of supply sockets, not have many electric wires to be wound around mutually.
Certainly, wireless charging technology also has following shortcoming:
1, efficiency is low: energy is deposited and sent efficiency not as good as true contact.
2, charging rate is slow: because efficiency is low, under same input power, charging rate is slower.
3, cost is high: at charger, need to there is the electronic circuit that promotes wireless coil, and the electronic installation that need to have electric power to change at power device, both also need to have wireless coil, so cost is than directly contacting as high.
Can not when mobile, charge: this problem only occurs on mobile device, for example electric shaver just can not move apart charger when charging, if the battery in electric shaver is just used up completely, at this moment electric shaver just can not be used, and the design that tradition connects with electric wire on the contrary can continue to use under the situation with the upper charger of electric wire connection on the contrary.
4, compatible low: the wireless charging device of different brands, because without unified standard, therefore can not lead to and change use.At present, industry has PMA.WPC.A4WP tri-Major Leagues, carries out separately different standards, has before the QI standard mesh that the maximum WPC of member's number carries out the whole world and has had numerous products and follow, and hope can reach to standard unified.
For the resident who lives in big city, rhythm of life is very fast, and almost everyone will use at least one cell phone apparatus.But intelligent machine large area is universal, and the standby of battery and cruising time are very short, and electric weight declines very fast, need charging at least one times in a day.And the bottleneck of this respect is insurmountable in nearly 5-10.Under rhythm of life faster, people's object is to use mobile phone, and the frequent charge of mobile phone has been become to an extra burden, and forgets that to be once in a while full of electric words can situation cumbersome.In a word, the use of existing charger has seemed extremely inconvenient.Thereby use the wireless charger of electromagnetic induction just to arise at the historic moment, but technical bottleneck causes this type of wireless charger reliability, and the aspects such as efficiency of transmission and cost are all weak spots.
