Description
Technical field
The utility model relates to a kind of protection equipment more particularly to a kind of pairing to protect charge power supply.
Background technique
The charge power supply of electronic equipment is corollary equipment, if using other similar charge power supply due to Current Voltage
It is different, it is easy to cause electronic equipment to burn out, but since existing charge power supply structure is closely similar, a charging plug also mould
Equally, and charge power supply relevant parameter index belongs to professional knowledge, therefore user in use can be due to misapplying it
His similar charge power supply and cause electronic equipment to damage.Ancillary equipment currently used for the mating charge power supply identification of electronic equipment
It not yet, therefore for the user is a bigger trouble.
Summary of the invention
The purpose of this utility model: provide it is a kind of for electronic equipment effectively identify pairing charge power supply pairing protection fill
Power supply.
To achieve the goals above, the technical solution of the utility model is:
A kind of pairing protection charge power supply, including equipment end tag and charge power supply connector circle, the equipment end tag
Identify that control chip, pairing code identifier, button vibration prompt piece and matching indicator light, the pairing identify control including pairing
It is logical that coremaking piece is connected respectively to pairing code identifier, button vibration prompt piece and matching indicator light, the pairing code identifier
Cross the electronic label code inside non-contact radio-frequency signal-obtaining charge power supply connector circle.
Charge power supply is protected in above-mentioned pairing, wherein the pairing identification control chip uses microcontroller core
Piece W78E051D.
Charge power supply is protected in above-mentioned pairing, wherein the pairing code identifier uses contactless nearly radiofrequency field
Read-write chip CV631.
Charge power supply is protected in above-mentioned pairing, wherein the button vibration prompt piece uses the flat button vibration of 3V
Motor.
The utility model can be inserted by being mounted in electronic equipment and its charge power supply in charge power supply charging head
The prompting whether matched is issued after electronic equipment charge port, so as to avoid using charging header structure being identical and Current Voltage not phase
With non-matching charge power supply and caused by electronic equipment burn.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model pairing protection charge power supply.
Fig. 2 is the schematic diagram of the utility model pairing protection charge power supply.
Specific embodiment
The embodiments of the present invention that the following is further explained with reference to the attached drawings.
Referring to Figure 1 and shown in Fig. 2, a kind of pairing protection charge power supply, including equipment end tag 1 and charge power supply connector
Circle 2, the equipment end tag 1 include pairing identification control chip 3, pairing code identifier 4, button vibration prompt piece 5 and
With indicator light 6, the described pairing identification control chip 3 be connected respectively to pairing code identifier 4, button vibration prompt piece 5 and
With indicator light 6, the pairing code identifier 4 passes through the electricity inside non-contact radio-frequency signal-obtaining charge power supply connector circle 2
Subtab code.
The pairing identification control chip 3 uses microcontroller chips W 78E051D.
The pairing code identifier 4 uses contactless nearly radiofrequency field read-write chip CV631.
The button vibration prompt piece 5 uses the flat button vibrating motor of 3V.The pairing identification control chip 3
By external triode, the on and off of the driving voltage of button vibration prompt piece 5 is controlled using I/O switch amount signal,
To control the vibration of button vibration prompt piece 5 and stop vibration operation.
The equipment end tag 1 is mounted on electronic equipment internal, and charge power supply connector circle 2 is mounted on electronic equipment charging
Inside power source charges head, after the charging head for the charge power supply arbitrarily taken out is inserted into the charge port of electronic equipment by user,
If it is the charge power supply of electronic equipment pairing, the pairing code identifier 4 on that equipment end tag 1 can be by contactless
Radiofrequency signal reads the electronic label code on the charge power supply connector circle 2 inside the charging head of charge power supply, and by the electricity
Subtab code is transferred to inside pairing identification control chip 3 by I2C interface, and due to the equipment end tag 1 and charge power supply
Connector circle 2 belongs to paired device, therefore the electronic label code inside charge power supply connector circle 2 has stored in pairing identification in advance
The inside for controlling chip 3, when pairing identifies that control chip 3 is read in the charge power supply connector circle 2 by matching code identifier 4
The electronic label code in portion, and by comparing the electronic label code for determining and reading, then generation consistent with the electronic label code of storage
The current charge power supply of table belongs to the mating charging equipment of the electronic equipment, and then pairing identification control chip 3 can control button
Vibration prompt piece 5 vibrates three times, represents equipment successful match, while lighting by the green light that I/O port controls matching indicator light 6, with
User of service's equipment successful match is prompted, then charge power supply can be linked into 220V AC power source to equipment by user of service
Effectively charged.
If after the charging head for the charge power supply arbitrarily taken out were inserted into the charge port of electronic equipment by user, pairing
Identification control chip 3 is read by pairing code identifier 4 less than any electronic label code, or the electronic label code that reads and
When the electronic label code of interior storage is inconsistent, represents current charge power supply and electronic equipment mismatches, then pairing identification control
The red light that chip 3 can control matching indicator light 6 by I/O port is lighted, and to prompt user of service's charge power supply to mismatch, is needed
It carries out with changing, is burnt to effectively prevent electronic equipment caused by mismatching power supply.
The utility model can be inserted by being mounted in electronic equipment and its charge power supply in charge power supply charging head
The prompting whether matched is issued after electronic equipment charge port, so as to avoid using charging header structure being identical and Current Voltage not phase
With non-matching charge power supply and caused by electronic equipment burn.
