The implementation principle of the embodiment is as follows: when the electronic equipment is crashed, a user only needs to slide the limiting sheet 24 and then presses the button to trigger the microswitch S1, and the connection point of the microswitch S1 and the grounding resistor R1 outputs high level. When a trigger signal, i.e., a high level signal, is input to the base of the first NPN transistor Q1, the first NPN transistor Q1 is turned on, and at this time, the gate of the P-channel fet Q2 is grounded through the first NPN transistor Q1. Since the P-channel fet Q2 has a characteristic of being turned on when the gate thereof is grounded, the drain of the P-channel fet Q2 outputs a high-level signal, i.e., a charge signal.

At this time, the charging signal, i.e. the high level signal, is received at one end of the charging capacitor C2, and the charging capacitor C2 starts to charge. Since the charging capacitor C2 generates current in the circuit during charging, the voltage across the third resistor R5 rises, and the connection point of the charging capacitor C2 and the third resistor R5 outputs a control signal, i.e., a high level signal. When the base of the second NPN transistor Q3 receives the high level signal, the second NPN transistor Q3 is turned on, and at this time, the enable end of the power control module and the GPIO _ EN pin of the processor are both grounded through the second NPN transistor Q3, so that the power control module is powered off, and at this time, the electronic device is powered off.

And in the charging process of the charging capacitor C2, the current flowing through the third resistor R5 gradually decreases, at this time, the potential of the connection point of the third resistor R5 and the charging capacitor C2 gradually decreases, when the base potential of the second NPN type triode Q3 decreases to the on-state voltage, the second NPN type triode Q3 is turned off, at this time, the P-channel field effect transistor Q2 still keeps the on-state, the enable end of the power control module is connected to the VCC end through the P-channel field effect transistor Q2, so that the power control module is turned on again, the power control module supplies power to the processor to turn on the processor, and the GPIO _ EN pin outputs a high level.

When the first NPN transistor Q1 is turned on, the first capacitor C1 is in a discharging state, and the voltage level of the terminal connected to the gate of the P-channel fet Q2 drops to a low level. And the first NPN transistor Q1 turns off when the trigger signal is turned off by the user's finger being removed. At this time, the first capacitor C1 starts to charge, the gate voltage of the P-channel fet Q2 gradually increases, the P-channel fet Q2 is turned off and the charging signal is turned off when the gate voltage reaches the cut-off voltage of the P-channel fet Q2, so that the delay effect of the charging signal is achieved, and the on-time of the P-channel fet Q2 is longer than the on-time of the second NPN type triode Q3.

And when the P-channel field effect transistor Q2 is cut off, the power control module is connected with the GPIO _ EN pin of the processor, so the power control module and the GPIO _ EN pin are still kept in an opening state, and the restarting operation is completed. During the period, the user only needs to slide and press the limiting sheet 24 of the electronic equipment to restart the electronic equipment, so that the operations of disassembling and assembling the battery or plugging and unplugging the power head are reduced, the maintenance time is shortened, and the maintenance efficiency is improved.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
