When inputing to the direct impulse of electronic lock certain voltage, when being positive 12V pulses under normal circumstances, electronic lock locking, work as input
When electron locks the reverse impulse of certain voltage, electronic lock unblock.Ought input to LOCKA voltage signal be more than input to
During LOCKB voltage signal, for example when the voltage signal for inputing to LOCKA is+12V, the voltage signal for inputing to LOCKB is 0V
When, or it is 0V to input to LOCKA voltage signal, when the voltage signal for inputing to LOCKB is -12V, is locked equivalent to electron
Input direct impulse；When the voltage signal for inputing to LOCKA is less than the voltage signal for inputing to LOCKB, such as when inputing to
LOCKA voltage signal is 0V, when the voltage signal for inputing to LOCKB is+12V, or inputs to LOCKA voltage signal
For -12V, when the voltage signal for inputing to LOCKB is 0V, input reverse impulse is locked equivalent to electron.
At present charging pipette tips electronic lock control circuit there is a problem in that：1st, it is powered to be based on system for electronic lock control circuit
When to electronic lock control, when the unexpected dead electricity of system power supply, or entire car controller be not related to electronic lock solution lock control all the way
It is active when outputing, electronic lock can not be just controlled, if now charging electric vehicle does not complete, then, electronic lock just can not
Unblock, user can not just disconnect the connection of electric automobile and power network, and then can not be continuing with electric automobile；If the 2nd, system power supply
Normal operation, charging electric vehicle complete when entire car controller terminate it is above-mentioned it is active all the way output, electronic lock unblock, in electronic lock
In releasing process, if now there is External force interference charging pipette tips, electronic lock will unlock failure, and then occur asking with above-mentioned 1st
Inscribe the problem of identical.No matter unblock failure, the pipette tips that charge can not smoothly be extracted from electric automobile, caused caused by which kind of reason
Bad Consumer's Experience.
The content of the invention
It is an object of the invention to provide a kind of charging electric vehicle pipette tips electronic lock control device, to solve system power supply
Dead electricity or entire car controller be not related to electronic lock solution lock control active when outputing all the way, if charging electric vehicle is not complete

Embodiment
Electrical lock apparatus embodiment 1
The present embodiment provides a kind of electrical lock apparatus, including two parts, is electronic lock and control device respectively, control device
For controlling electronic lock, therefore, the electrical lock apparatus is a kind of electronic lock with specific control device.In the present embodiment, electricity
Son lock is by taking charging electric vehicle pipette tips electronic lock as an example.Because electronic lock belongs to routine techniques, and the inventive point of the present invention
Not on electronic lock, therefore, the present embodiment is not just described in detail in itself to electronic lock, is only had to electronic lock control device
Body explanation.
Control device includes control module, first switch module, second switch module and the 3rd switch module, such as Fig. 2 institutes
Show, control module has a detection port, and the detection port is act as：For detecting system power supply whether dead electricity and/or
Whether entire car controller has related to electronic lock solution lock control all the way active output.Control module control connection first switch mould
Block, second switch module and the 3rd switch module, control the conducting of these three switch modules.
System power supply is the power supply of whole electrical lock apparatus, and when system power supply dead electricity, whole electrical lock apparatus is just
Can dead electricity.It is above-mentioned it is active output be entire car controller it is related to electronic lock solution lock control all the way it is active output, the present embodiment
In, the road is active to output referred to as electronic lock control power supply.Certainly, whether You Gai roads are active outputs for entire car controller, i.e. electronic lock
Whether control power supply has electricity to depend on two factors, and first is exactly system power supply, the system power supply power supply total as one, when
During system power supply dead electricity, entire car controller can not just export that the road is active to be outputed；Second other factors, for example, artificial disturbance because
Element.In addition, the power supply VCC being hereinafter related to also is influenceed by system power supply, when system power supply dead electricity, power supply VCC is also
There is no voltage.Therefore, when system power supply dead electricity, entire car controller can not just export that the road is active to be outputed, and work as entire car controller
The road is not active when outputing, and the state of system power supply is but not necessarily.In the present embodiment, system power supply is by taking+12V1 as an example, vehicle
The active of controller is outputed by taking+12V2 as an example.
First switch module includes first port and second port, and second port is used for the positive input for connecting electronic lock
LOCKA；Second switch module includes the 4th port and fifth port, and the 4th port connects one with system power supply or active outputing
Related negative electricity pressure side, because active output of system power supply and entire car controller is 12V, then, the negative electricity pressure side
Voltage be -12V, so, when system power supply dead electricity or entire car controller do not have active output, the negative electricity pressure side is just changed into
Zero potential, voltage 0V.Fifth port is used for the reverse input end LOCKB for connecting electronic lock；3rd switch module includes the 7th
Port, the 8th port and the 9th port, the 7th port connection charging capacitor C positive terminal, in the present embodiment, charging capacitor C with
Exemplified by electrochemical capacitor, charging capacitor C negative pole end connects above-mentioned first port, and the 8th port connects above-mentioned 4th port, the
Nine ports connection system power supply positive terminal or connection it is active output, i.e. the 9th port connection+12V.
The function of first switch module and second switch module is identical with the switch of routine, is realized and switched according to control signal
Conducting or shut-off, the 3rd switch module is functionally similar to single-pole double-throw switch (SPDT), three ports realized according to control signal
Selectivity conducting.
When the system is normal, control module control first port is connected with second port, the 4th port of control and the 5th end
Mouth connection, i.e. the positive input LOCKA connection charging capacitors C of electronic lock negative pole end, the reverse input end LOCKB of electronic lock
Connection -12V, also, control module control the 7th port connected with the 9th port, then, the positive terminal+12V of system power supply or
The active positive terminal for outputing+12V connection charging capacitors C of person's entire car controller, charged for charging capacitor C, then, in charging electricity
In the charging process for holding C, a direct impulse, electronic lock locking are inputted equivalent to for electronic lock.
When system power supply dead electricity or entire car controller do not have active output, first port still connects with second port
Connect, the 4th port is still connected with fifth port, and the positive input LOCKA of electronic lock still connects charging capacitor C negative pole
End, still, due to system power supply dead electricity or entire car controller do not have it is active output, negative electricity pressure side -12V is with regard to vanishing electricity
Position, control module control the 7th port to be connected with the 8th port, then, charging capacitor C is finally put to reverse input end LOCKB
Electricity, lock a reverse impulse, electronic lock unblock equivalent to electron.
From the foregoing, control module realizes the control of whole device, then, control module can be control chip, lead to
