The second control terminal coupling of module 140.When main control module 130 judge the matching voltage of external loading 11 for first voltage when, it is main
Control module 130 and generate control signal to the first control terminal for exporting handover module 140 according to pre-set control programs, so that outputting cutting
The first voltage got by battery pack 110 is directly output to protection module 150 by mold changing block 140, to pass through protection module 150
First voltage is exported to external loading 11.When main control module 130 judge external loading 11 matching voltage for second voltage when,
Main control module 130 is then also according to pre-set control programs generation control signal respectively to the first control terminal for exporting handover module 140
With the second control terminal, the first voltage got by battery pack 110 is reduced to by second voltage with control output handover module 140,
And second voltage is exported to external loading 11 by protection module 150.Wherein, the control signal of the generation of main control module 130 is
High level signal.
In the present embodiment, main control module 130 is respectively coupled to the cathode and anode of external loading 11 by protection module 150
Afterwards, main control module 130 can also monitor whether external loading 11 has got first voltage or second voltage.Specifically, master control
Module 130 judges that in preset duration monitoring is by protection module 150 with whether being obtained at the coupling of the cathode of external loading 11
To first voltage or second voltage.Wherein, preset duration can be 3 minutes.If getting first voltage in preset duration,
Main control module 130 judges current external loading 11 also in couple state, so continue to output control signal to export switching
First control terminal of module 140, continues to export first voltage, so that battery pack 110 continues with control output handover module 140
Power to external loading 11.If getting second voltage in preset duration, main control module 130 also judges that current outside is born
Carry 11 also in couple state, and then continue to output control signal respectively to the first control terminal of output handover module 140 and the
Two control terminals, with control output handover module 140 continue by after decompression second voltage export so that battery pack 110 continue to
External loading 11 is powered.If not getting first voltage in preset duration, main control module 130 judges current external loading
11 is already off, and then stops outputing control signals to the first control terminal of output handover module 140, so that output handover module
140 interrupt output first voltages, and then battery pack 110 then stops powering to external loading 11.If do not obtained in preset duration
To second voltage, then main control module 130 judges that current external loading 11 is also already off, and then stops distinguishing control signal
Output is to the first control terminal and the second control terminal for exporting handover module 140, so that output handover module 140 is interrupted to the first electricity
The decompression of pressure, and the output to second voltage is interrupted, and then battery pack 110 just stops powering to external loading 11.
As shown in figure 4, export handover module 140 cathode with battery pack 110, protection module 150 and main control module respectively
130 couplings.In the present embodiment, output handover module 140 can be the input terminal of DC decompression device 141, i.e. DC decompression device 141
Coupled with the cathode of battery pack 110, the output terminal of DC decompression device 141 is coupled with protection module 150, DC decompression device 141
First control terminal is coupled with the CL1 ports of main control module 130, the second control terminal and the main control module 130 of DC decompression device 141
CL2 ports couple.
DC decompression device 141 is disabled state in original state, although that is, the input terminal of DC decompression device 141 can obtain
To first voltage, but DC decompression device 141 does not carry out first voltage decompression processing, and the home loop of DC decompression device 141
Disconnect, and then DC decompression device 141 does not export first voltage or second voltage in original state.In the present embodiment, DC decompression
Whether device 141 gets control signal to determine whether output voltage according to the first control terminal, and the root of DC decompression device 141
Whether control signal is got according to the second control terminal to determine whether boost in voltage is exported.When the first of DC decompression device 141
When control terminal gets the control signal of the output of main control module 130, DC decompression device 141 is somebody's turn to do according to what the first control terminal was got
Control signal, direct output state is changed into by the state of itself by original state.Therefore DC decompression device 141 is getting battery
After the first voltage of the input of group 110, which can be directly output to protection module 150 by DC decompression device 141, with logical
The protection module 150 is crossed to export first voltage to external loading 11.When the first control terminal of DC decompression device 141 and second are controlled
When end processed gets the control signal of the output of main control module 130, DC decompression device 141 is controlled according to the first control terminal and second
The control signal got is held, the state of itself is changed into reduced output voltage state by original state.Therefore DC decompression device
141 after the first voltage of the input of battery pack 110 is got, and DC decompression device 141 can should by internal reduction voltage circuit
First voltage is depressurized to second voltage, and is exported the second voltage after decompression to outside by the coupling with protection module 150
Load 11.In addition, after the first control terminal of DC decompression device 141 does not get control signal, DC decompression device 141 is by direct
Output state or reduced output voltage state return to original state.
Protection module 150 is IC chip, and is coupling in the circuit of voltage switching output device 100.Specifically,
One end of protection module 150 is respectively with exporting handover module 140, main control module 130 and the negative couplings of battery pack 110, protection
The other end of module 150 then respectively with the cathode of external loading 11 and the negative couplings of external loading 11.When protection module 150 is supervised
When measuring over-pressed, under-voltage, short-circuit or excess temperature, protection module 150 then cuts off the circuit for being coupled to external loading 11, to realize to electricity
Crush-cutting changes the protection of each module in output device 100.
