Description
Technical field
The present invention relates to electronic technology.
Background technology
Chinese patent 200710053730 discloses a kind of wireless power transmission, charging method and device thereof, form charging system by separate less radio-frequency emission of magnetic field circuit and less radio-frequency magnetic field induction charging circuit, less radio-frequency emission of magnetic field circuit adopts fixing frequency of oscillation launching electromagnetic wave, and the electromagnetic wave that less radio-frequency magnetic field induction power supply circuits adopt the frequency identical or close with the emission of magnetic field circuit to carry out self-oscillation and the emission of induction wireless radio-frequency (RF) magnetic field radiating circuit produces electric current and electrical equipment powered or rechargeable battery is powered.
Above-mentioned technology discloses the basic principle of less radio-frequency charging.In the prior art, a kind of charging equipment for mobile phone based on this principle is arranged, receive charger and the mobile phone charging plug constitutes, during use, charging plug is inserted the charging inlet of mobile phone, realize cell-phone charging with this by the user by an external radio frequency.Its weak point is a complex operation, compares with traditional wired charging modes, and only be to have saved one section electric wire, be not easy to use.
Summary of the invention
Technical problem to be solved by this invention is, a kind of new less radio-frequency charging device is provided, and is easy to use, and is easy to carry.
The technical scheme that the present invention solve the technical problem employing is, the less radio-frequency charging device is included as film coil, rectification unit and battery interface, and film coil is connected to battery interface by rectification unit.
Described rectification unit is a diode, and first end of film coil is connected to an end of battery interface by diode,, second end of another termination film coil of battery interface.Described film coil is provided with a stickup face.Described battery interface is provided with the conduction stickers.
Perhaps, described film coil is arranged on the paster, and the bottom surface of paster is provided with stickup face.
Further, described film coil is arranged between paster and the protective layer, and the bottom surface of paster is provided with stickup face.
The present invention also provides mobile phone and the computer, particularly panel computer that has aforementioned less radio-frequency charging device.
The invention has the beneficial effects as follows, can stick on the battery and use, particularly for the battery of mobile phone, film coil of the present invention and chip diode volume are little, can be attached on the battery, neither influence the normal mounting and the use of battery, phone complete machine also have no effect in appearance (being built in body).Especially, the present invention need not battery itself is done any change, has also saved the operation of plug charging plug on phone during use, and is extremely convenient.The present invention is simple in structure, and cost and failure rate are low, is widely used, and not only is applicable to the battery of mobile phone, also is applicable to the battery charge of panel computer and digital camera.
