Embodiment 1

[0019] This embodiment is suitable for batteries of mobile phones.

[0020] This embodiment includes a thin film coil 1, a diode 2 and a battery interface 3. The thin film coil 1 has two terminals, the first end is connected to one end of the battery interface 3 through the diode 2, and the second end of the thin film coil 1 is connected to the other end of the battery interface 3. one end. The thin film coil 1 can be set on one patch, or in the interlayer between two patches. For fixing to the battery, an adhesive layer is provided on one side of the film coil 1 . The battery interface can use a metal sheet coated with a conductive adhesive, so as to be fixed on the electrode of the battery.

[0021] The thin-film coil of this embodiment is used to receive electric energy transmitted in the form of radio frequency, and charge the battery after rectifying it into direct current through a diode. The circuit diagram is shown in figure 2 .

[0022] The rectification circuit ...

Embodiment 2

[0024] see image 3 . The difference between this embodiment and Embodiment 1 is that the thin film coil of this embodiment is arranged on the patch 4, and the bottom surface of the patch 4 has an adhesive surface for fixing the coil on the battery.

Embodiment 3

[0026] The difference between this embodiment and Embodiment 1 is that the thin film coil of this embodiment is arranged between the patch 4 and the protective layer 5 to form an interlayer. The bottom surface of the patch 4 has an adhesive surface for fixing the coil on the battery.

[0027] The thin film coil and wires of the present invention can be made of flexible materials to adapt to certain curved batteries.

Abstract

The invention discloses a wireless radio frequency charging device and a mobile phone and a computer having the same, which relate to an electronic technique. The wireless radio frequency charging device comprises a thin film coil, a rectifying unit and a battery interface, wherein a chip radio frequency receiver is connected to the battery interface through the rectifying unit. The wireless radio frequency charging device is convenient to use, simple in structure, low in cost and fault rate and wide in application range.

Description

technical field [0001] The present invention relates to electronic technology. Background technique [0002] Chinese patent 200710053730 discloses a wireless energy transmission, charging method and its device. The charging system is composed of a wireless radio frequency magnetic field transmitting circuit and a wireless radio frequency magnetic field induction charging circuit that are independent of each other. The wireless radio frequency magnetic field transmitting circuit uses a fixed oscillation frequency to emit electromagnetic waves. The wireless radio frequency magnetic field induction power supply circuit uses the same or similar frequency as the magnetic field transmitting circuit to perform self-oscillation and induces the electromagnetic waves emitted by the wireless radio frequency magnetic field transmitting circuit to generate current to supply power to electrical appliances or rechargeable batteries. [0003] The above technology discloses the basic princip...
