Specific embodiment
It is new to this practicality below in conjunction with accompanying drawing to make the purpose of this utility model, technical scheme and advantage clearer Each implementation method of type is explained in detail.However, it will be understood by those skilled in the art that each in the utility model In implementation method, in order that reader more fully understands the application and proposes many ins and outs.But, even if without these skills Art details and many variations based on following implementation method and modification, it is also possible to realize the application technical side required for protection Case.
First embodiment of the present utility model is related to a kind of electronic equipment.The electronic equipment can be mobile phone, flat board electricity The smart machines such as brain.
The electronic equipment, including mainboard, USB connector, processor, charging circuit and the temperature for detecting USB connector The temperature detector of degree.Wherein, USB connector, processor and charging circuit are installed on mainboard;Temperature detector is installed In the region of temperature that can reflect USB connector on mainboard;And USB connector, temperature detector and charging circuit difference Electrically connected with processor (as shown in Figure 1).
The processor can be CPU (central processing unit), DSP (Digital Signal Processor, at data signal Reason device), or MCU (Microcontroller Unit, micro-control unit).The temperature detector can be TEMP Device, temperature detection chip, or one include the temperature sensing circuit of thermistor.
Specifically, in present embodiment, the temperature detector can be used to detect the temperature of USB connector.Processor can use In the temperature of the USB connector for obtaining the detection, and the temperature is compared with default first threshold.The first threshold can The factors such as the temperature of actual conditions, local environment according to equipment flexibly set, and present embodiment is without limitation.
If the temperature of current USB connectors is less than the first threshold, processor also needs to continue to obtain USB connector Temperature.In present embodiment, the frequency that the temperature that processor obtains USB connector can be set is 1/2Hz, i.e., double acquisition The time interval of the temperature of USB connector is 2s.
If the temperature of current USB connectors is more than or equal to the first threshold, processor can then disconnect the charging of battery Circuit, in case USB connector temperature is further up.
Present embodiment, the temperature of USB connector is detected by temperature detector, and in the temperature of the USB connector During more than or equal to default first threshold, voluntarily disconnect battery charging circuit, so as to avoid USB connector temperature after It is continuous to rise, the potential safety hazard that too high temperature is brought is reduced, be conducive to the safety of preferably protection equipment and user.
Second embodiment of the present invention is related to a kind of charge protector.Second embodiment is in first embodiment On the basis of the further improvement done, mainly the improvement is that:In second embodiment, processor disconnects the charging of battery After circuit, when the temperature of USB connector is less than or equal to Second Threshold, can also turn-on battery again charging circuit.
Specifically, in present embodiment, processor also may proceed to obtain and be somebody's turn to do after the charging circuit for disconnecting battery The temperature of USB connector, and judge the temperature whether less than or equal to default Second Threshold.The Second Threshold should be that equipment is each The normal temperature that subelement can bear, and the Second Threshold should be less than first threshold.
If it is determined that the temperature of USB connector is more than the Second Threshold, processor can then continue to obtain the USB connector Temperature.
If it is determined that the temperature of USB connector is less than or equal to the Second Threshold, processor can turn-on battery again Charging circuit, makes equipment recover charged state.
Further optionally, in present embodiment, processor can also be less than or wait in the temperature for judging current USB connectors Whether it is more than Second Threshold in the temperature of the USB connector for after the Second Threshold, determining whether last time acquisition.If last time obtains USB connector temperature be more than Second Threshold, then illustrate USB connector temperature decline, now, processor can weight The charging circuit of new turn-on battery, makes equipment recover charged state.That is, the charging circuit of turn-on battery needs to meet again Two conditions, one be this obtain USB connector temperature be less than or equal to Second Threshold;Two is that the USB for obtaining last time connects The temperature for connecing device is more than Second Threshold.This mode is conducive to accurately determining USB connector temperature the fact declining, and reduces False Rate, so that the preferably personal safety of protection equipment and user.
Similarly, during charging, processor is more than or equal to the first threshold in the temperature for judging current USB connector After value, can also determine whether the temperature of USB connector of last time acquisition whether less than first threshold.If the USB that last time obtains The temperature of connector is less than first threshold, then illustrate that the temperature of USB connector rises, and now, processor can disconnect electricity The charging circuit in pond.That is, the charging circuit for disconnecting battery is also required to meet two conditions, one is the USB that this is obtained The temperature of connector is more than or equal to first threshold;Two be last time obtain USB connector temperature be less than first threshold.
So that first threshold is 60 DEG C, Second Threshold is 45 DEG C as an example:
In charging process, if temperature >=60 DEG C of this USB connector for obtaining, the USB connector that last time obtains Temperature<60 DEG C, then disconnect charging circuit;
After charging circuit is disconnected, if temperature≤45 DEG C of this USB connector for obtaining, the USB connections that last time obtains The temperature of device>45 DEG C, then restart charging circuit.
Additionally, it is noted that when temperature detector is the temperature sensing circuit that includes thermistor, will can be somebody's turn to do Thermistor is arranged on can be reflected in the region of temperature of USB connector.Processor can be current by obtaining the thermistor Resistance, and the temperature of USB connector is obtained according to the corresponding relation of thermistor resistance and temperature.
Specifically, a groove 24 can be opened up at the position of the correspondence USB connector of mainboard 21, and thermistor 23 is placed in In the groove 24, and make thermistor that (as shown in Figure 2 A) is contacted with mainboard and USB connector respectively.Also can be opened up on mainboard One groove, USB connector is placed in the groove, while thermistor is located between USB connector and the cell wall of groove, and (as shown in Figure 2 B) is contacted with cell wall and USB connector respectively.Also only USB connector can be placed in the groove of mainboard, and incite somebody to action Thermistor is placed on the edge of groove, i.e., against the position of groove, (Fig. 2 C show that thermistor is placed on groove edge Top view).
Present embodiment, after the temperature of USB connector is fallen, it is not necessary to which user interferes, processor can again Start charging circuit, be conducive to further improving the intellectuality of equipment and the experience of user.
It will be understood by those skilled in the art that the respective embodiments described above are to realize specific implementation of the present utility model Example, and in actual applications, can to it, various changes can be made in the form and details, without departing from spirit of the present utility model And scope.
