Accompanying drawing explanation
Fig. 1 is circuit block diagram of the present utility model.
Fig. 2 is circuit diagram of the present utility model.
Detailed description of the invention
As it is shown in figure 1, this utility model is a kind of electronic lock drive circuit, drive including capacitance energy storage module 2 and power
Dynamic model block 4.Described capacitance energy storage module 2 is connected with power driver module 4, the external small-power power of capacitance energy storage module 21,
Power driver module 4 external door interlock switch signal 3 and the solenoid 5 of electronic lock.Merit is passed through after capacitance energy storage module 2 energy storage
Rate drives module 4 can be powered solenoid 5.
As in figure 2 it is shown, capacitance energy storage module 2 includes DC+ end and the DC-end phase of electric capacity C1, electric capacity C1 and small-power power 1
Even, the two ends of solenoid 5 are connected to MS+ end and the MS-end of circuit, and described power driver module 4 includes optical coupling
Device U1 and audion Q1, solenoid 5 is in parallel with electric capacity C1 after series connection audion Q1.When audion Q1 disconnects, electric capacity C1
Charging, after electric capacity C1 is full of, MS+ voltage is identical with DC+ voltage, it is achieved that electric capacity C1 stores up electricity.When audion Q1 turns on,
Solenoid 5 is powered by electric capacity C1.Described small-power power 1DC+ end is provided with a resistance R1, solenoid 5 and electric capacity C1
Connect with resistance R1 respectively.Resistance R1 primarily serves metering function, and when need not frequently open the door, the resistance value of resistance R1 is permissible
Take is big, and the biggest then door lock power of resistance value can be the least.When the tank voltage discharge off on electric capacity C1, due to
The existence of current limiting resistance R1, then the voltage on door lock solenoid 5 is the lowest, and solenoid 5 length conduction time also will not burn out.
Being in series with a unilateral diode D1 on described audion Q1, unilateral diode D1 is in parallel with solenoid 5.Audion Q1 disconnects
Time, no-voltage between MS+, MS-, solenoid 5 dead electricity, unilateral diode D1 is used for solenoid 5 afterflow, prevents audion
Q1 damages.
Described photo-coupler U1 includes 1 foot, 2 feet, 3 feet, 4 feet, and wherein 1 foot and 2 feet are input, believes with door interlock switch
The V+ end of numbers 3 is connected with V-end, and 3 feet, 4 feet are outfan, are connected with DC+ end and the DC-end of small-power power 1, and export
End also trigger electrode with audion Q1 is connected.When 1 foot and 2 feet have level signal, 3 feet, 4 feet just can turn on, and give audion
Q1 level signal, enables audion Q1 to turn on.When 1 foot and 2 feet do not have level signal, 3 feet, 4 feet disconnect, audion Q1's
Trigger electrode voltage is 0, and audion Q1 disconnects.The input of described photo-coupler U1 is in series with resistance R2, to reduce optical coupling
The voltage of the input of device U1.The outfan of described photo-coupler U1 is provided with resistance R3 and resistance R4, small-power power 1
Voltage drives audion Q1 conducting through R3, R4 dividing potential drop to suitable level.
This utility model is when solenoid 5 dead electricity, and electronic lock is in closure state, now electric capacity C1 charging, until
When MS+ voltage is identical with DC+ voltage, electric capacity C1 is full of.When needing to open electronic lock, control door interlock switch signal 3 and send electricity
Ordinary mail number, photo-coupler U1 just can send level signal to audion Q1, controls audion Q1 conducting, and electric capacity C1 is to solenoid
5 power supplies.When the tank voltage discharge off on electric capacity C1, due to the existence of current limiting resistance R1, then on door lock solenoid 5
Voltage is the lowest, and solenoid 5 length conduction time also will not burn out.This utility model uses capacitance energy storage mode to power, with the least
Power power-supply 1 replaces large power supply, cost to be substantially reduced, and takes up room little, and it is long for conduction time to avoid solenoid 5
The drawback that can burn out.
