[0042] Reference Figure 1 The utility model proposes a notebook performance mode switching circuit; the performance mode switching circuit comprises:
[0043] The physical switch circuit 10 is disposed in a notebook; the physical switch circuit 10 is used to output a trigger signal corresponding to a voltage value when triggered in different ways;
[0044] The detection module 20 has an input end connected to the output end of the physical switch circuit 10, and an output end connected to the control module of the notebook; the detection module 20 is used to detect the trigger signal output by the physical switch circuit 10, and convert the voltage value of the trigger signal into a corresponding instruction and output it to the control module to achieve notebook performance mode switching.
[0045] It should be noted that the existing notebook switching performance mode generally uses a specific shortcut key or needs to enter a specific software interface to select and change. This solution uses a physical switch and a detection module 20 set on the notebook to quickly switch the performance mode of the notebook; wherein, the physical switch circuit 10 includes a physical switch, and the physical switch is set on the shell of the notebook; in one embodiment of the utility model, the physical switch includes a single-pole switch, a toggle switch or a plurality of key switches, etc. In addition, the present application also realizes the switching of the notebook in three performance modes through the cooperation of the physical switch circuit 10 and the detection module 20. In particular, the physical switch includes a single-pole triple-throw switch, a four-pin toggle switch FP or three key switches, etc. The physical switch circuit 10 is used to output a first signal when triggered in a first manner, and is used to output a second signal when triggered in a second manner, and is also used to output a third signal when triggered in a third manner.
[0046] It is easy to understand that in one embodiment of the utility model, the user can make the physical switch move to achieve three different postures; when the physical switch is in the first posture, the physical switch circuit 10 is triggered in the first way and outputs the first signal; when the physical switch is in the second posture, the physical switch circuit 10 is triggered in the second way and outputs the second signal; when the physical switch is in the third posture, the physical switch circuit 10 is triggered in the third way and outputs the third signal. In one embodiment of the utility model, the physical switch includes a first key switch, a second key switch and a third key switch. The first key switch, the second key switch and the third key switch are in an interlocked state. When one of the key switches is pressed, the other two key switches are automatically released. When the first key switch is pressed, the physical switch circuit 10 outputs the first signal; when the second key switch is pressed, the physical switch circuit 10 outputs the second signal; when the third key switch is pressed, the physical switch circuit 10 outputs the third signal.
[0047] The input end of the detection module 20 is connected to the output end of the physical switch circuit 10, and the output end is connected to the control module of the notebook. It should be noted that the signal output by the physical switch circuit 10 is a switch signal. However, the change of the relevant performance mode of the notebook requires corresponding instructions to be realized; so the detection module 20 needs to convert the signal output by the physical switch into a corresponding instruction and output it to the control module, so as to realize the performance switching of the notebook computer. In an embodiment of the utility model, the first signal is related to the efficiency module; after detecting the first signal, the detection module 20 converts the first signal into an efficiency mode instruction and outputs it to the control module to realize the switching of the notebook mode to the efficiency mode. The notebook can have three modes, namely, efficiency mode, balance mode and low power consumption mode; wherein, when the notebook is in the efficiency mode, the power consumption is the highest and the operating frequency is the highest; when it is in the low power consumption mode, the power consumption is the lowest and the operating frequency is the lowest; when it is in the balance mode, the power consumption is lower than the power consumption of the efficiency mode, but higher than the power consumption of the low power consumption mode, and the operating frequency is lower than the operating frequency of the efficiency mode, but higher than the operating frequency of the low power consumption mode. The control module of the notebook may include a CPU.
[0048] The utility model proposes a notebook performance mode switching circuit, the performance mode switching circuit comprising: a physical switch circuit 10, arranged in a notebook; the physical switch circuit 10, used to output a trigger signal of a corresponding voltage value when triggered in different ways; a detection module 20, the input end of which is connected to the output end of the physical switch circuit 10, and the output end is connected to the control module of the notebook; the detection module 20 is used to detect the trigger signal output by the physical switch circuit 10, and convert the voltage value of the trigger signal into a corresponding instruction and output it to the control module, so as to realize the notebook performance mode switching. The utility model detects the signal output by the physical switch circuit 10 when it is triggered by the user through the detection module 20, and converts the detected trigger signal into a corresponding instruction and outputs it to the notebook control module, so as to realize the notebook performance module switching.

[0052] A four-pin toggle switch FP has a first end connected to the first input end of the detection module 20, a second end and a third end connected to the ground, and a fourth end connected to the second input end of the detection module 20; the four-pin toggle switch FP is used to connect its two adjacent ports when triggered.
[0053] In this embodiment, the user toggles the four-pin toggle switch FP so that the physical switch circuit 10 outputs the first signal, the second signal or the third signal. As can be seen from the structure of the four-pin toggle switch FP, the paddle of the four-pin toggle switch FP can slide between the four ports of the four-pin toggle switch FP, connecting two of the four ports at a time. Therefore, the four-pin toggle switch FP has three gears. When the paddle connects the first end and the second end, the first input end of the detection module 20 is grounded and a low level is detected; the second input end of the detection module 20 is connected to the first voltage signal through the second resistor R2 and a high level is detected. When the paddle connects the second end and the third end, the first input end of the detection module 20 is connected to the first voltage signal through the first resistor R1 and a high level is detected; the second input end of the detection module 20 is connected to the first voltage signal through the second resistor R2 and a high level is detected. When the paddle connects the third end and the fourth end, the first input end of the detection module 20 is connected to the first voltage signal through the first resistor R1 and a high level is detected; the second input end of the detection module 20 is grounded and a low level is detected.
[0054] In one embodiment of the utility model, when the first input end of the detection module 20 detects a low level and the second input end detects a high level, the detection module 20 outputs an efficiency mode instruction to the control module; when the first input end of the detection mode detects a high level and the second input end detects a high level, the detection module 20 outputs a balance mode instruction to the control module; when the first input end of the detection module 20 detects a high level and the second input end detects a low level, the detection module 20 outputs a low power consumption mode instruction to the control module.
[0055] The first voltage may be output by a power supply circuit in the notebook.
[0056] In an embodiment of the present utility model, the physical switch circuit 10 further includes:
[0057] A voltage protection circuit, wherein the first input end is connected to the first end of the four-pin toggle switch, and the second input end is connected to the fourth end of the four-pin toggle switch; the voltage protection circuit is used to be turned on and grounded when the value of the first voltage is greater than a first predetermined value, so as to avoid high voltage damage to the detection module 20;
[0058] The debouncing circuit is arranged in the circuit between the four-pin toggle switch FP and the detection module 20, and is used to filter out the high-frequency signal component of the output signal of the four-pin toggle switch FP when the four-pin toggle switch FP is triggered in the first mode or in the third mode, so as to avoid jitter of the signal received by the detection module 20.
[0059] In this embodiment, the voltage protection circuit may include a TVS diode, which is turned on and grounded when the value of the first voltage is greater than the first predetermined value.

Correspondingly, the drain and source of the second MOS transistor are arranged in an electrical loop between the second end of the second resistor R2 and the second input end of the detection module 20, the first input end of the second operational amplifier is connected to the voltage access end 110, the second input end is connected to the first predetermined value voltage, and the output end is connected to the gate of the second MOS transistor; thereby, when the value of the first voltage is greater than the first predetermined value, the path between the second end of the detection module 20 and the second end of the second resistor R2 is cut off, so as to avoid the value of the first voltage being too high and damaging the detection module 20. The first predetermined value can be determined by R&D personnel.
[0060] Considering that the switch shakes when being pressed, it is not conducive to the detection of the detection module 20 and may lead to an erroneous detection result; therefore, an anti-jitter circuit is provided in the circuit between the four-pin toggle switch FP and the detection module 20 to filter out the high-frequency signal component of the output signal of the four-pin toggle switch FP, thereby avoiding the jitter of the signal received by the detection module 20.
