Embodiment
The embodiment of the disclosure is described in detail below in conjunction with attached drawing.It should be appreciated that this place is retouched
The embodiment stated is only used for describing and explaining the disclosure, is not limited to the disclosure.
Please refer to Fig.1, Fig. 1 is a kind of schematic diagram for electronic lock control device that the embodiment of the present disclosure provides.Such as Fig. 1 institutes
Show, electronic lock control device 100 includes：Electronic lock power supply 101, low side driving switch 102, relay 103.Low side driving switch
102 are connected with relay 103, and relay 103 is connected with electronic lock power supply 101.
In the low control signal when driving switch 102 receives low, relay 103 is attracted so that electronic lock power supply 101
The electric current of first flow direction is provided for electronic lock or the electric current of the second flow direction, the electric current in the first flow direction flow through electricity
During son lock, electronic lock unlock, when the electric current in the second flow direction flows through electronic lock, electronic lock locking.
Alternatively, electronic lock control device further includes：Controller, is laid in BMS (Battery Management
System, battery management system) on mainboard.
Controller is connected with low side driving switch 102, coil of the low side driving switch 102 through relay 103 and power supply electricity
Pressure side 104 is connected, and one of ground terminal 105 and supply voltage end 104 are connected with electronic lock power cathode, and through relay
103 normally-closed contact is connected with electronic lock positive pole.
Specifically, A is please referred to Fig.2, Fig. 2A is the schematic diagram for the electronic lock control device that the embodiment of the present disclosure provides.Such as figure
Shown in 2A, ground terminal 105 is connected with electronic lock power cathode, and the normally-closed contact through relay 103 and electronic lock positive pole
It is connected.
B is please referred to Fig.2, Fig. 2 B are the schematic diagrames for the electronic lock control device that the embodiment of the present disclosure provides.As shown in Figure 2 B,
Supply voltage end 104 is connected with electronic lock power cathode, and the normally-closed contact through relay 103 and electronic lock positive pole phase
Even.
Whether it is powered according in the coil of relay 103, relay 103 there are two kinds of working statuses：Attracting state and non-suction
Conjunction state.Under non-pull state, no power in the coil of relay 103, the normally-closed contact of relay 103 remains stationary as, and
The normally opened contact of relay 103 is off.Under attracting state, it is powered in the coil of relay 103, produced by coil
Suction normally opened contact is attracted, and the normally-closed contact of relay 103 is off.
For the electronic lock control device shown in Fig. 2A, during relay 103 is operated in non-pull state, electronic lock electricity
Source cathode and electronic lock power cathode are connected with ground terminal, are not present between electronic lock positive pole and electronic lock power cathode
Pressure difference, does not have electric current in electronic lock by the way that the working status before electronic lock is in off working state or keeps is constant.If control
Device processed to the low control signal when driving switch 102 applies low, such as：Low side driving switch 102 is set to connect 0V, low side driving switch
Pressure difference is formed between 102 and supply voltage end 104, has in the coil of relay 103 from the driving of supply voltage end 104 to low side and opens
The electric current in 102 directions is closed by the way that suction caused by coil is attracted the normally opened contact of relay 103 so that electronic lock power supply
Cathode is connected with supply voltage end 104, and since electronic lock power cathode is originally connected with ground terminal 105, so electronic lock is electric
There are pressure difference between source cathode and electronic lock power cathode, have in electronic lock from electronic lock positive pole to electronic lock power cathode
The electric current in direction is by the way that namely the electric current of the first flow direction flows through electronic lock so that electronic lock unlocks.
Similarly, for Fig. 2 B shown in electronic lock control device, during relay 103 is operated in non-pull state, electricity
Son lock positive pole and electronic lock power cathode are connected with supply voltage end 104, electronic lock positive pole and electronic lock power supply
Pressure difference is not present between anode, does not have electric current in electronic lock by the way that electronic lock is in the work before off working state or holding
State is constant.If controller to the low control signal when driving switch 102 applies low, such as：Connect low side driving switch 102
0V, forms pressure difference between low side driving switch 102 and supply voltage end 104, have in the coil of relay 103 from supply voltage end
104 to low 102 direction of side driving switch electric current by, suction caused by coil is attracted the normally opened contact of relay 103,
So that electronic lock positive pole is connected with ground terminal 105, and due to electronic lock power cathode originally with 104 phase of supply voltage end
Even, so there are pressure difference between electronic lock positive pole and electronic lock power cathode, have in electronic lock from electronic lock power cathode
To electronic lock positive pole direction electric current by the way that namely the electric current of the second flow direction flows through electronic lock so that electronic lock is locked
Only.
As it can be seen that the electronic lock control device provided using the embodiment of the present disclosure, can be in controller to low side driving switch
102 apply low side control signal so that the normally opened contact of relay 103 is attracted, and then realizes the control to electronic lock working status
System.Due to relay 103 itself inexpensively, so the cost for the electronic lock control device that the disclosure provides is relatively low, it is adapted to big
Batch production.
Alternatively, low side driving switch 102 switchs for metal-oxide-semiconductor.Since metal-oxide-semiconductor switch itself is relatively cheap, it is possible to
Further reduce the cost for the electronic lock control device that the embodiment of the present disclosure provides.
Alternatively, according to the flow direction of the electric current flowed through in electronic lock, the working status of electronic lock can be divided into lock
Determine state and released state.Such as：If there is the electricity from electronic lock positive pole to electronic lock power cathode direction in electronic lock
Stream passes through, namely the electric current of the first flow direction flows through electronic lock, then electronic lock is operated in released state；If have in electronic lock
From electronic lock power cathode to the electric current in electronic lock positive pole direction by the way that namely the electric current of the second flow direction flows through electronics
Lock, then electronic lock is operated in lockup state.
