Abstract
The utility model relates to a high-efficiency wireless charging mobile phone comprising a coil (1), a mobile phone (2), a coil (3) and a power supply (4). The high-efficiency wireless charging mobile phone is characterized in that the coil (1) is connected on the power supply (4); and the coil (3) is arranged in the mobile phone (2). The charging device with energy exchange mode of electromagnetic field has simple manufacture, low cost and high energy utilization ratio and can realize wireless charging of various low-power electronic products of mobile phones and the like.
Description
Technical field
The utility model relates to the wireless charging field, relates in particular to wireless charging mobile phone, charging device and charging method.
Background technology
Present most of wireless charging technology only rests on experimental stage, does not enter practical application as yet.Existing wireless charging technology has following some deficiency: 1) general wireless charging device volume is all bigger, can only illustrative be some low power electronics instrument power supplies, as miniature bulb, small fan etc.; 2) energy transformation ratio of power supply process is very low, mainly is to change by electromagnetic field to transmit energy, and finishes the conversion of energy, and in conversion process, most of energy loss has been fallen.
Summary of the invention
The purpose of this utility model then is at above-mentioned the deficiencies in the prior art, provides a kind of volume small and exquisite, and the higher efficient wireless charging mobile phone of charge efficiency.
The purpose of this utility model can realize by following measure:
A kind of efficient wireless charging mobile phone and supporting wireless charger thereof comprise two coils, mobile phone, power supply, it is characterized in that a coil is connected on the power supply, and the another coil is built in the mobile phone.
Two above-mentioned coils can be circular, and a coil is external, and another coil is built-in.
The beneficial effects of the utility model have:
The charging device of the energy of electromagnetic field exchanged form that the utility model proposes is compared with existing all kinds of wireless charging devices, and making is simple, cost is low, capacity usage ratio is high, can be multiple low power electronics product realization wireless chargings such as mobile phone.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is further described below in conjunction with accompanying drawing:
As shown in Figure 1, the utility model is to be a built-in coil 3 in the mobile phone 2 at existing mobile phone, external coil 3 on power supply 4.With two copper coils as vibrotron.One of them coil 1 is connected that transmission of power is as reflector on the power supply 4, and another coil 3 is built in the mobile phone 2, as energy receiver, and the rechargeable battery in the mobile phone of ining succession.
After power supply 4 energising, coil 1 can be with certain frequency vibration as reflector, but its outside launching electromagnetic wave, and around it, form a powerful non-radiative magnetic field.This non-radiative magnetic field can coordinate to carry out power transfer with another coil 3 (being receiver).In this charging device, charging principle is just the same with electromagnetic viscosimeter as the electromagnetic induction phenomenon of using in transformer and the antenna, the operation that is 1 li electric current of transmitting coil equally makes 3 li inductions of receiving coil produce electric current, and this induced current of generation just is the rechargeable cellphone battery charging.
Charging process is as follows:
Step 1: coil 3 parts of mobile phone 2 are placed the charging zone of coil 1 formation, the vibrotron A of the wireless charging device that actuating coil 1 and power supply 4 are formed and the vibrotron B in the mobile phone 2;
Step 2: regulate the vibration frequency of vibrotron A, B, make them have identical vibration frequency; The principle of this method is: two objects of resonance, under the situation of common vibration frequency, can exchange energy each other, thereby reach the function of long-range charging, under the situation of fixing frequency, positive energy exchange in fixing electromagnetic field, wherein one section is fixed on place, power supply source, and another section then is fixed on the object place of needs chargings such as mobile phone;
Step 3: continue charging for vibrotron A, electric current is exported has electric current to produce on it, for rechargeable battery charges.
The electromagnetic viscosimeter that the utility model is taked can use energy to greatest extent, improves charge efficiency.
Optimization to technique scheme:
One, a pressurizer is installed on coil 3, the electric current that coil 3 produces through after the voltage stabilizing for rechargeable battery charges, as to be adjusted into magnitude of voltage be 4 to 5 volts, current value is 500 to 800 milliamperes a electric current of voltage regulation, is cell-phone charging.
Two, an electromagnetic field intensity change detecting device is installed in charging device, with on the external power source 4 that coil 1 links to each other the principal current switch being arranged is little current switch, this checkout gear divides test side A and test side B, lays respectively at mobile phone 2 both sides, wherein test side A be and coil 1 between mobile phone 2, test side B is positioned at the mobile phone other end, when not charging, close the principal current switch, only connect little current switch, make charging device be in power down mode, electromagnetic field intensity drops to minimum.If detect the electromagnetic field intensity of test side A and test side B tangible sudden change is arranged, then open the principal current switch automatically, make the charging device charged state.As the mobile phone 2 that will hang down electric weight during near coil 1, the electromagnetic field intensity that checkout gear detects test side A, B has obvious variation, because after the electromagnetic field of coil 1 emission passes mobile phone 2, portion of energy is attracted to become induced current by coil 3, electromagnetic field intensity has just died down, and checkout gear makes charging device be in charged state with regard to the principal current switch of self-opening power supply 4, and principal current switch, complete charge state are closed in charging when finishing.Thereby improve the automaticity of charging device, user-friendly, save energy simultaneously, neither charging does not generate an electromagnetic field.
The undeclared part that relates in the utility model is same as the prior art or adopt prior art to be realized.
