Description
Technical field
This utility model relates to wireless charging field, is specifically related to a kind of wireless charging output device.
Background technology
Wireless charger refers to that charge power supply line that need not be traditional is connected to the charger needed on the terminal unit of charging,
Have employed up-to-date wireless charging technology, used the magnetic field produced between coil by Inductive coupling techniques, transmit electric energy.
Implementing of wireless charging output device product, it is generally divided into power module, low-frequency current power transmission line, nothing
Line charging output circuit module, four parts of transmitting coil module, wherein said power module is generally adapter, Large Copacity electricity
Pond or other DC sources, described low-frequency current power transmission line is to be only suitable for conducted power unidirectional current and low frequency signal alternating current
Conventional electric wire, such as USB line.And described wireless charging output circuit module and two parts of described transmitting coil module typically can
Be arranged in same shell, or few in the case of be mounted in be divided into two or more part but close mechanical connects
In an assembly housing together.Is exactly that existing most wireless charging output device produces as disclosed in CN201220552440
The implementation of product, also has some wireless charging output device product by power module and wireless charging output circuit module, sends out
Ray circle module assembled, in a shell, does not use low-frequency current power transmission line, as disclosed in CN201220725129.
Owing to existing power converting circuit is the most inefficient and produce thermal losses, and do not have in the years ahead time
There is the possibility of upgrading, and in wireless charging output circuit module, necessarily include described power converting circuit, the most described wireless
Charging output circuit module turns communication process at direct current and produces many heats, such as exports the wireless charging system generation of 5W
Heat is typically no less than 1W, is equivalent to the heat of 2 little bulbs, and if upgrade to the wireless charging system of 15W or 20W,
The heat produced will reach 3W.This is during actually used wireless charging, and wireless charging output device can be to wireless charging
Electricity reception equipment transmits substantial amounts of heat, causes wireless charging to receive device temperature higher than temperature when directly charging with wire
A lot, affect the life-span of product and reduce the reliability of product, even causing in wireless charging reception equipment lithium battery etc. complete
Total loss is bad or explodes.
In order to solve the problems referred to above, the high-speed radio being not less than 15W especially realizing receiving equipment for wireless charging fills
Electricity, uses the wireless charging output device product of existing structure design, it is necessary to consider the transmission of described heat, distribute, with as far as possible
Reduce and be delivered to wireless charging and receive the heat of equipment, the thinking of design including, but not limited to increase overall length and width size and
Thickness, addition radiator fan even select the heat sink material of high price.Therefore made high-speed radio charging output device is similar to
Multiple writing cases stack, bulky；And adding rotating shaft fan in enclosure interior is wireless charging output circuit mould simultaneously
Block dispels the heat, and its purchase cost about account for the half of high-speed radio charger, but will necessarily be because of entering after a period of time uses
Ash, water inlet cause fan work bad or stop work, it is impossible to dispel the heat for wireless charging output device, and described rotating shaft fan
Can't dispel the heat specially for the launch site of wireless charging reception equipment.
Therefore, use existing structure design high-speed radio charger product, not only bulky and be not acceptable to the market,
And radiating effect is poor, the life-span is short, it it is a kind of jejune product.
Meanwhile, under high-speed radio charge condition, it is also the most considerable that wireless charging receives the heat of equipment self generation
, directly resulting in wireless charging reception device temperature and significantly raise, described wireless charging receives equipment and produces in charging process
Raw heat receives in the loss of chip, wireless charging reception equipment from copper loss, the wireless charging of wireless charging receiving coil
The heat produced when the heat produced during portion's PMU circuitry work and secondary cell charging, the heat that wherein PMU circuitry produces accounts for
Arrive a greater part of, and secondary cell has had and occupies about the half of remainder.Even if being embodied in employing conventional wire cable to enter
Row rapid charge, wireless charging receives equipment and also has significantly temperature rising.
Therefore, while carrying out high-speed radio charging, in addition it is also necessary to solve wireless charging and receive asking of equipment self-heating
Topic, and the problem of the heating of wireless charging output device, is one of the problem of those skilled in the art's primary study always.
On the other hand, traditional wireless charging emitter is in order to carry out high-speed and continuous interactive communication, typically with external device
Select NFC technique, by designing the communication antenna of NFC and the transmission circuit plate of NFC at wireless charging transmitting coil modular peripheral
Realize.But, in reality, the data link of NFC device is customized by each publisher with communications protocol layers, does not have general
Property, therefore behave as and have no idea to realize a universal NFC device and can carry out accessible logical with other all NFC device
Letter, even cannot receive the equipment NFC module that such as mobile phone, intelligent watch are built-in with common wireless charging and carry out accessible logical
Letter.Therefore NFC technique does not have the universal general-purpose capability of society, result also in the problems such as current popularization is very slow, system is incompatible.
And the high-frequency alternating current of conventional wireless charging technique employing wireless charging energy carries out AM/FM modulation as carrier wave and leads to
The technology of letter, is only suitable for extremely low transfer rate, the communication of very short time width, thus be accordingly used in intermittent regulation wireless charging transmission
Power is the most feasible, but if to expand at a high speed, long-time continuous communiction influence whether the stability of wireless charging,
And cause substantial amounts of energy loss to cause serious heating to cause danger.
And wireless charging emitter and external equipment especially wireless charging receives equipment such as mobile phone, intelligent watch and carries out
High-speed and continuous interactive communication, can be that Internet of Things provides effective service, strengthen the application of wireless charging emitter, therefore, need
Design a kind of have versatility again without interference with the high speed interactive communication mode of wireless charging energy transfer, be also this area
One of problem of technical staff's primary study always.

Wherein, ping-pong communication protocol is the vibration stopping blower unit 12 after output modulated signal in a period of time,
Start lasting pickup by pickup conditioning module 1442 simultaneously and monitor the input signal of outside air, when whole communication process terminates
Rear blower unit 12 starts again to start, and dispels the heat；Interval monitoring protocols is during the air blast heat radiation stage, inserts one section
The blower unit 12 out-of-work time period, utilize this time period blower unit 12 to carry out pickup and monitor outside air
Input signal and export modulated signal to external world, and continue to start blower unit 12 after sign off, and carry out air blast
Heat radiation；It is iteratively repeated above-mentioned steps, between blower unit 12 and pickup conditioning module 1442, realizes alternation.
As described above, only this utility model most preferred embodiment, it is not intended to limit scope of the present utility model,
All equivalence changes made according to this utility model claim or modification, be all this utility model and contained.
