Description

Radio receiver

Technical field

This utility model is related to wireless charging technical field, more particularly to a kind of radio receiver.

Background technology

Energy transmission technology just because of using the limitation of wire, in the mode transmitted to closed dielectric to not against medium , the transformation of the wireless transmission method of open space.Being wirelessly transferred for energy can be such that people have broken away from electricity consumption to wire Rely on, facilitate the life of people.

So, wireless energy supply technology is nearest increasingly hotter a special kind of skill risen, and is also occurred in that based on this each The wireless energy supply product of color various kinds, its essence are substantially and utilize electromagnetic induction principle, realize being wirelessly transferred for electric energy.

Wireless charger is generally divided into power coil module and receiving coil module two parts, yet with existing reception The receiving efficiency of coil module is limited so that the finite energy that receiving coil module is received, and this has resulted in most of wireless Charger all have the shortcomings that one it is universal --- charging effect it is not good or do not fill electricity phenomenon.This brings pole to user The earth inconvenience, while also allowing the convenience of wireless charging technology to be greatly limited.

Therefore, a kind of efficient reception device how is designed, is that the technology of the current urgent need to resolve of those skilled in the art is asked Topic.

Utility model content

The purpose of this utility model is to provide a kind of efficient radio receiver.

To reach above-mentioned purpose, what the technical solution of the utility model was realized in：1st, a kind of radio receiver, bag Include：Receiving coil module, the harmony module being connected with the receiving coil module and rectification module, are connected with the rectification module The voltage conversion IC module for connecing, wherein the harmony module is made up of inductive element and capacitive element, and connected mode is Transmitting coil module is in parallel with the inductive element, connects with the capacitive element；Or the transmitting coil module with The capacitive element is in parallel, connects with the inductive element.

Further, the capacitive element is ceramic disc capacitor or tantalum electric capacity.

Further, the receiving coil module is made up of enamel wire coil and lamellar magnetic shield.

Further, the enamel wire coil is generally circular in shape, oval, round rectangle.

Further, the number of plies of the enamel wire coil is 1 layer or 2 layers, a diameter of 0.1-0.3mm of the enamel-covered wire, Sub-thread wire harness is 2-5, and the coiling number of turns is that 15-20 is enclosed.

Further, the lamellar magnetic shield is soft ferrite material.

Further, the rectification module is semi-bridge rectifier module or full-bridge rectification module.

Further, the voltage conversion IC module adopts buck radio receiver, and its output voltage is 3.6V, 5V Or 12V.

This utility model is connected with harmony module by receiving coil module, according to electromagnetic induction principle, receiving coil Module receives magnetic field energy, and is translated into electric energy, and harmony module is made to adjust induction reactance and the capacitive reactance of radio receiver The energy of the magnetic field transmission of the more efficient reception characteristic frequency of coil energy.
