Meanwhile, the electronic product can save energy consumption on the basis of meeting the user requirements.
The technical solutions proposed by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of a power on/off control device of an electronic device according to an embodiment of the present application. As shown in fig. 1, the switch control apparatus 100 is connected to a power supply 200 and a main control module 301 of an electronic device 300. The startup and shutdown control device 100 includes: the device comprises a first switch module 101, a second switch module 102, a power control module 103 and a signal detection module 104.
The power supply 200 is connected to the first switch module 101, an output terminal of the first switch module 101 is connected to an input terminal of the power control module 103, and the first switch module 101 can provide an enable signal for the power control module 103. The power supply 200 is connected to the power supply input end of the power control module 103, and the output end of the power control module 103 is connected to the main control module 301 for supplying power to the main control module 301. The input end of the power control module 103 is connected to the main control module 301, and the power control module 103 can obtain a stable and continuous enable signal through the main control module 301.
The output end of the first switch module 101 is connected to the input end of the signal detection module 104, the output end of the signal detection module 104 is connected to the main control module 301, the detection signal generated by the signal detection module 104 can be transmitted to the main control module 301, and the main control module 301 can control the corresponding sub-device of the electronic device 300 according to the detection signal. The power supply 200 is connected to the second switch module 102, and the second switch module 102 is connected to the input end of the power control module 103, and is configured to provide an enable signal for the power control module 103.
After the detection signal generated by the signal detection module 104 is transmitted to the main control module 301, the main control module 301 may control the corresponding sub-device to operate according to the detection signal and a preset instruction. The preset instructions, the control instructions, the number of the sub-devices, and the like of the main control module 301 are not limited in the present application.
In this embodiment, the main control module 301 of the electronic device 300 is a single chip microcomputer, and the model of the single chip microcomputer may be STM32F030K6T 6.

The second zener diode D2, the third zener diode D3, the fourth zener diode D4 and the seventh zener diode D7 are used for avoiding the mutual influence of different enable signals.
Specifically, the pin 3 of the power management chip U4 is connected to the cathode of the second zener diode D2, the cathode of the third zener diode D3, the cathode of the fourth zener diode D4, and the cathode of the seventh zener diode D7, respectively. An anode of the seventh zener diode D7 is connected to one end of the sixteenth resistor R16 and one end of the seventeenth resistor. After the direct current power supply of the third switch module is connected, the direct current power supply needs to be divided by the sixteenth resistor R16 and the seventeenth resistor R17, and then external direct current power is input to the third pin of the power management chip U4, so that the situation that the voltage of the direct current power supply is too high and the power management chip U4 is damaged is avoided.

The tenth resistor R10 may have a resistance of 100K Ω, the eighteenth resistor R18 may have a resistance of 200K Ω, and the tact switch SW1 may have a model number of K2-1806 SA.
In practical use, after the key of the tact switch SW1 is pressed, the pin 5 of the tact switch SW1 is short-circuited with the pin 6, and the current of the power supply flows through the second zener diode D2 after being divided by the tenth resistor R10 and the eighteenth resistor R18, so as to provide a high level for the pin 3 of the power management chip U4.
In some embodiments of the present application, a circuit diagram of the signal detection module, as shown in fig. 5:
the signal detection module comprises a third field effect transistor N3, a fifth resistor R5 and a seventh resistor R7. The resistance of the fifth resistor R5 may be 10K Ω, and the resistance of the seventh resistor R7 may be 100K Ω. The drain D of the third field effect transistor N3 is connected to one end of the fifth resistor R5, and serves as the output end of the signal detection module, and is connected to the second end of the main control module. The other end of the fifth resistor R5 is connected to the first end of the main control module, one end of the seventh resistor R7 is connected to the gate G of the third field effect transistor, and is used as the input end of the signal detection module, and is also connected to the output end BUTN _ BUCK _ IN of the first switch module, and the other end of the seventh resistor R7 is connected to the source of the third field effect transistor N3.
When the output terminal BUTN _ BUCK _ IN of the first switch module is at a high level, the input terminal of the signal detection module is at a high level, the third field effect transistor N3 is turned on, the drain G of the third field effect transistor N3 is at a low level and sends a first low level detection signal to the main control module, and the main control module receives a detection signal of the output terminal BUTN _ DECT of the third field effect transistor N3 at a low level, so that the main control module controls the corresponding sub-device according to the detection signal and a preset instruction.
In some embodiments of the present application, the second switch module may be a mechanical key module, a circuit of the mechanical key module is shown in fig. 6, and the mechanical key module includes: a time delay unit 900, a mechanical key switch SW2, and a fourth resistor R4. Wherein, the resistance of the fourth resistor is 10K omega.
One end of the fourth resistor R4 is connected to the power supply, and the other end of the fourth resistor R4 is connected to the fourth pin of the mechanical key switch SW 2. A third pin of the mechanical key SWITCH SW2 is connected to a first end of the delay unit 900, and a second end of the delay unit 900 is used as an output terminal SWITCH _ BUCK _ EN of the second SWITCH module and is connected to an anode of a fourth zener diode D4 in the power control module.
Further, the delay unit 900 includes a fifth zener diode D5, a tenth capacitor C10, a fourteenth resistor R14, and a fifteenth resistor R15. The tenth capacitor C10 may be of a type C0402, the fourteenth resistor R14 may have a resistance of 10K Ω, and the fifteenth resistor R15 may have a resistance of 200K Ω.

In an actual use process, when the mechanical key switch SW2 is closed, that is, the third pin and the fourth pin in the mechanical key switch SW2 are short-circuited, after the power voltage is divided by the fourth resistor R4 and the fourteenth resistor R14, two ends of the tenth capacitor C10 are half of the power voltage, and two ends of the tenth capacitor C10 are connected through the fifth voltage stabilizing diode D5 to form a discharge loop. Under the slow discharge of the fifteenth resistor R15 with a larger resistance, the other end of the tenth capacitor C10 will slowly become low level, so that the delay unit YS outputs an electrical signal of a pulse waveform. When the main control module is powered on, and does not receive the detection signal, and also determines that the third switch module is not triggered, the main control module may determine that the second switch module is triggered.
In some embodiments of the present application, the third switching module may be a dc power module, and a circuit of the dc power module is as shown in fig. 7, and the dc power module includes a charging management chip U6, a second resistor R2, a third resistor R3, a seventh capacitor C7, and a thirtieth resistor R30.

A pin 6 of the charging management chip U6 is connected to one end of the third resistor R3 and the third end of the main control module respectively; a seventh pin of the charging management chip U6 is connected to one end of the second resistor R2 and the fourth end of the main control module, respectively; the other end of the second resistor R2 is connected to the other end of the third resistor R3 and to the first end of the main control module.
Specifically, after the dc power is powered on, the first terminal PWR _ IN of the third switching module provides an enable signal for the power control module, and the pin 5 of the charging management chip U6 can output a charging current to charge the power supply, so as to ensure a continuous power-on state of the power supply, thereby supporting the normal operation of the switching control device. The charge management chip U6 may generate and send two status signals to the master control module via pins 6 and 7 of the charge management chip U6.
When the dc power supply is not energized, the pin 6 of the charging management chip U6 goes low and the pin 7 goes high, and after the dc power supply is energized, the pin 6 of the charging management chip U6 goes high and the pin 7 goes low. The main control module judges whether the direct current power supply is connected according to the states of the pin 6 and the pin 7 of the charging management chip U6, so that the corresponding sub-equipment is controlled.
It should be further noted that the second switch module may use the same tact switch module as the first switch module. The second switch module can also adopt a direct current power supply module which is the same as the third switch module, and the second switch module is matched with the first switch module to realize on-off control. For the combination of a plurality of switches, the main control module can judge which switch is triggered, and the number of the set switches is not limited.
Based on this, in the above scheme, the signal of the signal detection module and the signal sent to the main control module by the charging management chip can enable the main control module to distinguish two switch modules, and further can distinguish a third switch module. Through the startup and shutdown control device, the control of different working states of the electronic equipment is realized, and then the requirements of users are met and the energy is saved.
