Embodiment
To make technical staff more fully understand the utility model, embodiment of the present utility model is carried out with reference to the accompanying drawings
Describe in detail, but not as to restriction of the present utility model.
As shown in accompanying drawing 1 to accompanying drawing 6, the present embodiment provides a kind of locking device of charging connector for electric automobile, including
Locking mechanism and state detection mechanism.Locking mechanism includes coil motor 40, the gear drive 50 by motor driving, connection
The locking bar 10 of gear drive；Locking bar includes engaging the groove portion of connection and accessible microswitch with gear train assembly
Lug boss 11.State detection mechanism includes normally closed microswitch S120 and its contact 21 and normally closed microswitch S230 in parallel
And its contact 31；State detection mechanism also includes the resistance R122 to be connected with normally closed microswitch S1 and normally closed microswitch S2
Resistance R232, the detection module of connecting interface PIN3, PIN4 of series connection.Detection module detects circuital current and judges locking device
State.Resistance value R1 is that 1K Ω, R2 are 2K Ω.
The operation principle of locking device described above is as follows：
First, accompanying drawing 1, accompanying drawing 2 show the released state of charging connector for electric automobile locking device.When unblock locks
During device, coil motor 40 and gear train assembly 50 drive locking bar 10 inwardly to bounce back, and locking bar lug boss 11 contacts microswitch
S1 contact 21, normally closed microswitch S120 is opened, it is R2 to make circuit all-in resistance, forms electric current I1, state detection module detection
Circuital current simultaneously judges released state.
Accompanying drawing 3, accompanying drawing 4 show the intermediateness of charging connector for electric automobile locking device.When coil motor 40 and
During the driving locking bar 10 of gear train assembly 50 moves out, locking device does not also reach locking state nor unblock shape
State, this hour locking lever are not contacted with normally closed microswitch S1 contact 21 and S2 contacts 31, and switch S120, S230 are turned off, and make electricity
Road all-in resistance is R1R2/ (R1+R2), forms circuital current I2, the equally detectable circuital current of detection module.
Accompanying drawing 5, accompanying drawing 6 show the locking state of locking device.Coil motor 40 and gear train assembly 50 drive
The dynamic motion of locking bar 10 forms locking state, and the lug boss 11 of this hour locking lever contacts normally closed microswitch S2 contacts 31, and fine motion is opened
Close S230 tops to open, it is R1 to make resistance in circuit, forms circuital current I3, and detection module detection circuital current simultaneously judges shape of locking
State.
In the present embodiment, detection module can connect signal lamp or display screen to show lock status.
Preferred embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model,
