Description
Technical field
The present invention relates to a kind of radio induction charging device, especially relate to a kind of radio induction charging receiving system of portable communication apparatus.
Background technology
At present the wireless technology that conducts electricity is mainly divided three kinds of electromagnetic induction, radio wave, electromagentic resonance.And which kind of technology no matter, the foundation stone that is achieved all comes from the electromagnetic coupling theory that michael faraday was found in 1831, and the wireless transmission of electricity conception established of Ni Gula tesla in 1890.The wireless charging technology is mainly utilized electromagnetic technique, at reflector electric current is converted into electromagnetism, and by specific built-in chip receiver electromagnetism being converted into specified electric current and voltage is that electronic product charges.
The before this professional domains that are applied in of wireless charging technology need to guarantee the place of product seal more, as medical treatment device in underwater installation, the body etc.But in the face of huge consumer level Equipment Market, this piece market still is in the starting stage, and at present because technology and standard uneven, various countries' voltage is disunity again, and each tame product remains at present at compatibility issue.
Along with increasing of household electronic equipment, the comprehensive application of electronic product allows the constraint of breaking away from cable become the public's demand, the growth of taking advantage of a situation of wireless charging technology, beginning in 2010, wireless charging, wireless energy transfer product will no longer be that what old name for the Arabian countries in the Middle East is talked night, fairy tale.Various wireless chargers, use wireless charging electronic product will be shown up prominently gradually in every field.The wireless charging technology not only can be the charging of portable set product, and it also will be used fast and develop at PMP/MP3 player, digital camera and notebook computer lamp product scope.According to the investigation of market survey mechanism, by 2013, global radio charging potential market capacity was near 14,000,000,000 dollars, and by 2014, the shipment amount of wireless charging device will reach 200,000,000 5 thousand ten thousand.
At present a lot of people for radio induction charging understand comprehensive inadequately, using this principle in fact, will to derive minimum altogether be two product designs, one is the radio induction charging emitter, one is the radio induction charging receiving system.At present a lot of based on the Chevron Research Company (CRC) of radio induction charging receiving system, though principle is the same, the circuit difference of design is inferior uneven, and a lot of technical indicators such as emission effciency, tranmitting frequency, transmitting power, transmitting range, quiescent dissipation also are not quite similar.
Existing wireless induction receiving system mainly contains following several at present:
(1) use leather sheath and plastics back splint, the copper coil of wireless induction is equipped with in the inside, and power-switching circuit; Because it uses plastic casing or cortex overcoat, products such as portable set will customize, otherwise interface do not go up, and volume is excessive and thick.
(2) use the copper coil of wireless induction, power-switching circuit is contained in portable set back cover the inside, but it is applied in and needs to customize the die sinking tool on the mobile portable product, and the construction cycle is long, and mould takes expensive non-general user and bears, and success rate is low and authenticate and bother.
(3) with the copper coil of wireless induction, be contained in the box of a circle or shape such as square with power-switching circuit, export with lead again after the reception, still the electric energy of wireless induction need be injected portable set afterbody charging inlet by the usb data line, that is not as good as the electricity that directly will the export portable set afterbody charging inlet of directly plugging into.
(4) with the copper coil of wireless induction; be contained in the battery with power-switching circuit; the soft bag of the plastics that use macromolecule electricity core does not have the protection of metallic hard material shell; and electric core space availability ratio is the highest can only to be reached this way of 70% existing market and exists and reduce the effective usage space of battery significantly, causes the portable set effective storage life to shorten greatly.Simultaneously because of directly causing portable set correctly to show charged state and utilizing portable set to manage battery charging management and protection and shutoff to battery charge.Also have simultaneously because of not having metal shell to protect electric core to cause long-term unsaturated charging or overcharging the rise danger of tripe even blast of the portable set battery that causes.
To sum up, various radio energy induction receiving systems are multifarious, can solve that receiving system separates with machine but can't resolve cost and the volume problem, unseparatedly exist product customization, construction cycle to check and balance again, the product cost expense increases, replaceability easy consumption product is made of one, can causes product such as whole portable set normally to use because the radio induction charging receiving system damages; Prior art (4) has made things convenient for products in circulation though the surface has overcome the problems referred to above, separates with the product body.But, caused battery to wait the danger of rise tripe and easier blast because of heating owing to used the shell of nonmetal electric core.Simultaneously because adopt a large amount of copper coils to cause the battery product confined space can only reach about 70% of original volume.
Therefore, press for develop have versatility, safe wireless charging receiver, to satisfy the demand in technical development and market.
