Abstract
The utility model discloses a kind of magnetic-type charge and discharge device, including the magnetic-type interface for connecting external power source or device to be charged, charging circuit, booster circuit, module I C and rechargeable battery, the magnetic-type interface connects rechargeable battery by charging circuit with booster circuit, module I C controls connection charging circuit and booster circuit, the beneficial effects of the utility model are：When magnetic-type interface accesses external device (ED), detection is now that internal charging battery is charged or external device (ED) is discharged, and then control the connection of charging circuit or booster circuit and rechargeable battery, a magnetic-type interface, which can be achieved, can realize that charge function can also realize discharging function, so that carrying the equipment volume miniaturization of this magnetic-type charge and discharge device, can be widely used in the apparatus for storing electrical energy such as flashlight, portable power source.
Description
Technical field
A kind of charge and discharge device is the utility model is related to, specifically a kind of magnetic-type charge and discharge device.
Background technology
The flashlight or portable power source of the existing magnetic-type charge function of band, typically an only magnetic interface is to mobile phone
Internal cell is charged.If to utilize battery electric quantity to set mobile phone such as to charge to outside, mobile phone is needed to connect another
USB interface.Because with two interfaces, it is also desirable to which designer does flashlight or portable power source bigger, can just put down
Two interfaces, are highly detrimental to the Miniaturization Design of product, also have impact on Consumer's Experience in use.
Utility model content
The purpose of this utility model is to provide a kind of magnetic-type charge and discharge device, to solve to propose in above-mentioned background technology
The problem of.
To achieve the above object, the utility model provides following technical scheme：
A kind of magnetic-type charge and discharge device, including for connecting the magnetic-type interface of external power source or device to be charged, filling
Circuit, booster circuit, module I C and rechargeable battery, the magnetic-type interface connect charging with booster circuit by charging circuit
Battery, module I C controls connection charging circuit and booster circuit.
As further program of the utility model：The magnetic-type interface connects for the D/C power of more sizes and more profiles
Mouthful.
As the utility model further scheme：The module I C is provided with the power threshold of rechargeable battery.
As the utility model further scheme：The output voltage of the booster circuit is 5V.
Compared with prior art, the beneficial effects of the utility model are：When magnetic-type interface accesses external device (ED), detection
It is now that internal charging battery is charged or external device (ED) is discharged, and then controls charging circuit or booster circuit
With the connection of rechargeable battery, you can realize that a magnetic-type interface can realize that charge function can also realize discharging function so that
The equipment volume miniaturization of this magnetic-type charge and discharge device is carried, the electricity such as flashlight, portable power source can be widely used in
In energy storage device.
Brief description of the drawings
Fig. 1 is a kind of schematic diagram of magnetic-type charge and discharge device.
Fig. 2 is the structural representation for the flashlight for being equipped with this magnetic-type charge and discharge device.
Embodiment
The technical scheme of this patent is described in more detail with reference to embodiment.
Referring to Fig. 1, a kind of magnetic-type charge and discharge device, including for connecting the magnetic of external power source or device to be charged
Formula interface, charging circuit, booster circuit, module I C and rechargeable battery, the magnetic-type interface pass through charging circuit and boosting electricity
Connection rechargeable battery in road is rechargeable battery powered or is exported the internal electric energy of rechargeable battery to device to be charged, module I C
Charging circuit and booster circuit are connected simultaneously, when magnetic-type interface accesses external device (ED), detection is now to charge inside electricity
Pond charge or external device (ED) is discharged, and then controls the connection of charging circuit or booster circuit and rechargeable battery,
A magnetic-type interface, which can be achieved, can realize that charge function can also realize discharging function so that carry this magnetic-type charge and discharge
The equipment volume miniaturization of electric installation, strengthens Consumer's Experience；The magnetic-type interface connects for the D/C power of more sizes and more profiles
Mouthful；The module I C is provided with the power threshold of rechargeable battery, automatic to disconnect when the electricity in rechargeable battery reaches given threshold
Charging circuit or booster circuit, protected with being formed to rechargeable battery, prevent low battery or too high rechargeable battery is caused damage；
The output voltage of the booster circuit is 5V.
Exemplified by being equipped with the flashlight of this magnetic-type charge and discharge device, as shown in Fig. 2 flashlight is by placket 2, rear cylinder 3
Formed with tail pipe 5, rechargeable battery 4 is fixed on inside flashlight by tail pipe 5 with rear cylinder 3 by threaded engagement, and placket 2 is provided with magnetic
Suction interface 1, magnetic-type interface 1 connect rechargeable battery 4 with booster circuit by charging circuit, and module I C connects charging electricity simultaneously
Road and booster circuit, when flashlight is charged, external power source is connected by magnetic-type interface 1 with flashlight, now mould
Block IC is determined as charged state, then controls magnetic-type interface 1 to be realized by charging circuit and the UNICOM of rechargeable battery 4 to charging electricity
The charging in pond 4, when the electricity in rechargeable battery 4 reaches the threshold value of setting, module I C control charging circuits disconnect automatically；When need
When being charged to external device (ED), such as when mobile phone is linked on flashlight, module I C judges that now state is charging, then
Magnetic-type interface 1 is controlled to realize the charging to mobile phone, the electricity in rechargeable battery 4 by booster circuit and the UNICOM of rechargeable battery 4
Measure it is too low, when reaching the threshold value of setting, module I C control booster circuit disconnect automatically.
The better embodiment of this patent is explained in detail above, but this patent is not limited to above-mentioned embodiment party
Formula, can also be on the premise of this patent objective not be departed from one skilled in the relevant art's possessed knowledge
Make a variety of changes.
