Fig. 2 is the schematic flow sheet of the embodiment step of the method for keeping electric power of equipment of the present invention.
[embodiment]
As shown in Figure 1, keep the embodiment framework of the device 1 of electric power of equipment in order to expression the present invention.Among the figure, the device 1 of keeping electric power of equipment of the present invention be applied to have charhing unit 20 and to should charhing unit the electronic equipment 2 of 20 set charging control unit 21, as PDA(Personal Digital Assistant), notebook computer (NoteBook) and mobile phone (Cell Phone) etc.; And this charging control unit 21 has temperature protection mechanism; and after being used to receive power supply 3; to this charhing unit 20 and this electronic equipment 2 charges respectively and the processing of powering (for clear expression power supply is handled; among the figure electronic equipment 2 main bodys that are powered with system's 2 ' expression); wherein; the better embodiment of this charhing unit 20 is a rechargeable battery, and the better embodiment of this charging control unit 21 is one group of charging control integrated circuit (Charger IC).The state detecting module 11 that this device 1 of keeping electric power of equipment comprises switch element 10 and electrically connects with this charging control unit 21 and this switch element 10.
Below device 1 described above-mentioned each object of promptly keeping electric power of equipment at the present invention respectively elaborates:
This switch element 10 electrically connects with parallel way and this charging control unit 21, its preset state is for opening (OFF), that is, these switch element 10 formed circuits present off state (open), just under normal condition, this power supply 3 is to provide the system 2 ' of electric power to this electronic equipment 2 via these switch element 10 formed circuits.
This state detecting module 11 is in order to detect the state of this charging control unit 21, and when the state of this charging control unit 21 is abnormal condition, make this switch element 10 closures (ON), that is, make these switch element 10 formed circuits present short-circuit condition (short) so that this power supply 3 can be directly by these switch element 10 formed circuits to the processing of powering of the system 2 ' of this electronic equipment 2.
Above-mentioned state detecting module 11 further comprises temperature detecting unit 110 that electrically connects with this charging control unit 21 and the operating state detecting unit 111 that electrically connects with this charging control unit 21, wherein, this temperature detecting unit 110 is in order to detect the temperature of this charging control unit 21, and when the temperature of this charging control unit 21 is higher than preset temperature value, make this switch element 10 closures; And this operating state detecting unit 111 is in order to detecting the operating state of this charging control unit 21, and when being wrong, makes this switch element 10 closures in the operating state of this charging control unit 21.
In other words; the state of the charging control unit 21 that aforesaid state detecting module 11 is detected is meant to be detected (wherein the temperature and the operating state of this charging control unit 21; the temperature of this charging control unit 21 is meant that this charging control unit 21 is for the measured temperature of this charhing unit 20; and the operating state of this charging control unit 21 is meant that whether this charging control unit 21 is because of recording this charhing unit 20 for damaging; and decommission); and after detecting, judge; if the operating state that the temperature of this charging control unit 21 is higher than preset temperature value or this charging control unit 21 when wrong (that is; this charging control unit 21 decommissions); then make this switch element 10 closures; and then make these switch element 10 formed circuits present short-circuit condition; allow power supply 3 be transferred to the system 2 ' of this electronic equipment 2 no longer indirectly via this charging control unit 21; but see through the system 2 ' that these switch element 10 formed circuits are directly given electric power transfer this electronic equipment 2; therefore; even this charging control unit 21 is because of the too high start-up temperature protection mechanism of temperature or because of these charhing unit 20 damages; cause himself to present to decommission (shut down) state, the power supply that does not also influence this electronic equipment 2 is handled.
Above-mentioned preset temperature value is meant that this charging control unit 21 is own at the default temperature value of temperature protection mechanism.
Again as shown in Figure 2, in order to represent the embodiment steps flow chart of keeping the method for electric power of equipment of the present invention.Among the figure, the method of keeping electric power of equipment of the present invention is applied to have charhing unit and to the electronic equipment of should charhing unit set charging control unit, as PDA(Personal Digital Assistant), notebook computer (Note Book) and mobile phone (Cell Phone) etc.; And this charging control unit has temperature protection mechanism; and after being used to receive power supply; this charhing unit and this electronic equipment are charged respectively and power processing; wherein; the better embodiment of this charhing unit is a rechargeable battery, and the better embodiment of this charging control unit is one group of charging control integrated circuit (Charger IC).This method of keeping electric power of equipment is execution in step S10 at first.
This step S10 electrically connects switch element and this charging control unit with parallel way earlier, and this step is opened the circuit of (OFF) state of switch unit in order to be pre-formed a tool.Then proceed to step S11.
This step S11, detect the state of this charging control unit, detailed speech, this step is meant the temperature (as step S110) and the operating state (as step S111) of this charging control unit of detecting, wherein, the temperature of this charging control unit is meant this charging control unit for the measured temperature of this charhing unit, and the operating state of this charging control unit is meant whether this charging control unit is damage because of recording this charhing unit, and decommissions.Then proceed to step S12.
This step S12, whether the state of judging this charging control unit is normal, if not, then proceed to step S13, detailed speech, this step is meant whether the temperature of judging this charging control unit is higher than preset temperature value (as step S120) and judges whether the operating state of this charging control unit is wrong (as step S121), if wherein one for being, then proceed to step S13, then return if not to step S11, continue the state of this charging control unit of detecting, that is, the temperature and the operating state of lasting this charging control unit of detecting.
This step S13 makes this switch element closure (ON), that is, make the formed circuit of this switch element present short-circuit condition, can directly see through the formed circuit of this switch element for this power supply and give this electronic equipment electric power transfer.
In sum, the device and method of keeping electric power of equipment of the present invention, it sees through this switch element and electrically connects with parallel way and this charging control unit, and detect the state of this charging control unit by the state detecting module, and when the state of this charging control unit is abnormal condition, make this switch element closure, so that this power supply can be directly sees through the formed circuit of this switch element to the processing of powering of this electronic equipment, therefore, can avoid the too high or charhing unit (rechargeable battery) of Yin Wendu to damage that institute causes can't be to the power problem of processing of electronic equipment, therefore, no matter whether the residing ambient temperature of electronic equipment is too high or whether charhing unit damages, all can allow this electronic equipment when the input power supply, possess required electric power.
