Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art are not making under creative work prerequisite, and the every other embodiment obtained, all belongs to scope.
Core of the present invention is to provide a kind of protective device for preventing overheat and electronic equipment of electronic equipment.
In order to make those skilled in the art person understand the present invention program better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Embodiment one
Fig. 1 is the structural drawing of the protective device for preventing overheat of a kind of electronic equipment provided by the invention.As shown in Figure 1, the protective device for preventing overheat of electronic equipment comprises:
Correspondence is arranged at the temperature-detecting device 11 at target detection parts 10 place in electronic equipment, for detecting the temperature value of target detection parts 10, and exports power-off signal when temperature value exceedes preset temperature value;
The power control circuit 12 be connected with temperature-detecting device 11, for when receiving power-off signal, disconnecting the electric power supply of electronic equipment, being in off-mode to make electronic equipment;
Wherein, the quantity of temperature-detecting device 11 and the quantity one_to_one corresponding of target detection parts 10.
In Fig. 1, show 3 target detection parts 10 and temperature-detecting device 11.In concrete enforcement, according to occurring in electronic equipment that the parts of the too high phenomenon of temperature are as target detection parts, therefore, the quantity of target detection parts is also different in different electronic equipments.Temperature-detecting device 11 is separately positioned on target detection parts 10 annex, has several target detection parts 10 just to need to arrange several temperature-detecting device 11.The effect of temperature-detecting device 11 is the temperature signals detecting the target detection parts 10 corresponding with it, and temperature value corresponding for this temperature signal and preset temperature value are compared, when this temperature value exceedes preset temperature value, temperature-detecting device 11 can send power-off signal to connected power control circuit 12.After power control circuit 12 receives power-off signal, disconnect the electric power supply of electronic equipment, be in off-mode to make electronic equipment.
Be understandable that, as long as because power control circuit 12 receives the electric power supply that power-off signal will disconnect electronic equipment, off-mode is in make electronic equipment, therefore, no matter temperature-detecting device 11 has several, as long as the temperature value of the target detection parts 10 corresponding with it exceedes preset temperature value to have one of them temperature-detecting device 11 to detect, then electronic equipment will shut down.
The protective device for preventing overheat of the electronic equipment that the present embodiment provides; by arranging a temperature-detecting device for each target detection parts; temperature-detecting device detects the temperature signal of target detection parts; when detecting that the temperature value of target detection parts exceedes preset temperature value, send power-off signal to connected power control circuit.After Energy control power supply receives power-off signal, the electric power supply of electronic equipment is disconnected, be in off-mode to make electronic equipment.This protective device for preventing overheat can play a protective role when any one target detection part temperatures is too high in the electronic device.
Wherein, power control circuit 12 for disconnecting the connection of electronic equipment and extraneous power supply, or disconnects the battery of electronic equipment.
The battery that has had due to electronic equipment can be its power supply by battery, the battery that do not have had then needs directly to be connected with extraneous power supply to think that it is powered, therefore, power control circuit 12 can be shut down to make electronic equipment by the connection disconnecting electronic equipment and extraneous power supply; Also can be shut down to make electronic equipment by the battery disconnecting electronic equipment.
Wherein, temperature-detecting device 11 is temperature sensor.
The type of temperature sensor has multiple, can select according to actual conditions.
Fig. 2 is the structural drawing of the protective device for preventing overheat of another kind of electronic equipment provided by the invention.As shown in Figure 2, as one preferred embodiment, the protective device for preventing overheat of electronic equipment, also comprises: be arranged at the AND circuit 13 between temperature detection part 11 and power control circuit 12;
Wherein, temperature-detecting device 11 exports high level signal when temperature value does not exceed preset temperature value, and power-off signal is low level signal; Power control circuit 12 disconnects the electric power supply of electronic equipment after receiving low level signal, is in off-mode to make electronic equipment.
In concrete enforcement, can AND circuit 13 between temperature-detecting device 11 and power control circuit 12.Due to the characteristic of AND circuit 13, therefore, in the present embodiment, when temperature value does not exceed preset temperature value, temperature-detecting device 11 exports high level signal, the temperature-detecting device 11 output low level signal when temperature value exceedes preset temperature value.All temperature-detecting devices 11 are all connected with AND circuit 13, and therefore, when one of them temperature-detecting device 11 output low level signal, then AND circuit 13 will output low level signal.Therefore, when power control circuit 12 after AND circuit 13 output low level signal just disconnects the electric power supply of electronic equipment.
Wherein, on the basis of above-described embodiment, target detection parts 10 comprise central processing unit, graphic process unit and/or mainboard.
Be understandable that, all parts on electronic equipment can become target detection parts 10, but if all parts all carry out overheating protection, then electronic equipment volume can be caused excessive, also there is no need.Therefore, the present embodiment can using central processing unit, graphic process unit and/or mainboard as target detection parts 10.Such as, target detection parts 10 have three, are respectively central processing unit, graphic process unit, mainboard.
Because the anti-overheating protection temperature value of different parts is different, therefore, the preset temperature value of each temperature-detecting device 11 needs to set according to the actual conditions of target detection parts 10.
1) when target detection parts 10 are central processing unit, the preset temperature value of temperature-detecting device 11 correspondence is 90 degrees Celsius.
2) when target detection parts 10 are graphic process unit, the preset temperature value of temperature-detecting device 11 correspondence is 85 degrees Celsius.
3) when target detection parts 10 are mainboard, the preset temperature value of temperature-detecting device 11 correspondence is 75 degrees Celsius.
It should be noted that, the temperature characterisitic that different target detection parts are corresponding is different, and therefore, the preset temperature value in temperature-detecting device needs the temperature characterisitic according to the target detection parts corresponding with it and arranges.
