It is as follows respectively that the safety device of electric automobile charging pile charging port of the present utility model, door are opened the workflow of closing with door:
One, door is opened workflow
The first step: the control signal that the central controller of the single-chip microcomputer detection electric automobile charging pile in the single chip machine controlling circuit 13 sends, and judge, if detect start signal, then carry out next step;
Second step: it is the forward rotation signal that single chip machine controlling circuit 13 sends the forward rotation pulse by the Stepping Motor Driver interface end to stepping motor 4;
The 3rd step: after stepping motor 4 received the forward rotation signal, by shaft driven gear 8 forward rotation of stepping motor 4, thereby gear 8 drove tooth bar 9 positive movements that are fixed on the door 2, opens door 2; Single chip machine controlling circuit 13 blocks if meet accident by blocking the signal that the signal read circuits interface end reads Hall element 11 simultaneously, then changes accident over to and blocks program, otherwise carry out next step;

Two, door is closed workflow
The first step: the control signal that the central controller of the single-chip microcomputer detection electric automobile charging pile in the single chip machine controlling circuit 13 sends, and judge, if the shutdown signal of detecting is then carried out next step;
Second step: it is the backward rotation signal that single chip machine controlling circuit 13 sends the backward rotation pulse by the Stepping Motor Driver interface end to stepping motor 4;
The 3rd step: after stepping motor 4 received the backward rotation signal, by shaft driven gear 8 backward rotation of stepping motor 4, thereby gear 8 drove tooth bar 9 counter motions that are fixed on the door 2, closes door 2; Single chip machine controlling circuit 13 blocks if meet accident by blocking the signal that the signal read circuits interface end reads Hall element 11 simultaneously, then changes accident over to and blocks program, otherwise carry out next step;
The 4th step: when door 2 is closed fully, the infrared reflection of correspondence position reads the circuit interface end near switch sensor 7 by switching signal and sends the end signal of closing the door to single chip machine controlling circuit 13, single chip machine controlling circuit 13 sends the pulse that stops operating by the Stepping Motor Driver interface end to stepping motor 4 then, the motor stop motion has realized closing fully of door.
Three, accident is blocked program
The first step: meet accident when blocking, Hall element 11 blocks signal by blocking the signal read circuits interface end to single chip machine controlling circuit 13 transmission accidents;
Second step: single chip machine controlling circuit 13 sends rightabout pulse signal by the Stepping Motor Driver interface end to stepping motor 4, door 2 counter motions, move to that state of opening fully or closing, open or close motion when recovering something unexpected happened after the of short duration time-delay;
The 3rd step: if above-mentioned motion is finished, then EOP (end of program) is waited for subcommand down; Otherwise, changed for second step over to, if triplicate still can not be finished motion, then door 2 can remain on opposite state, namely closes the state of (or unlatching) fully, waits for that the maintenance personal handles.
When the user need give charging electric vehicle, by swiping the card, the door that starts the electric automobile charging pile charging port was opened workflow, treat that door is opened fully after, the user can charge; Also be same reason when door is closed, after the user pulls out plug from charging socket, start door and close workflow, thereby make door close the safety of protection electric automobile charging pile charging port fully.
If door is in closing closed procedure, after the user pulls out plug from charging socket, in time from the charging pile housing, do not take out, door will block charging plug when closing so, can not realize closing fully, at this moment single chip machine controlling circuit is not owing to detect the end signal of closing the door, can continue to send shutdown signal to stepping motor, and door is because block charging plug, do not produce mobile, tooth bar on the door does not have motion yet so, the gear supporting with tooth bar do not rotate yet, if gear does not rotate, the Hall element feedback signal just no longer changes so, because single chip machine controlling circuit constantly sends turn signal to stepping motor, and the Hall element signal of feedback does not change, judge relatively that by this door accident blocks, block program thereby change the door accident over to, realize that the accident of door is blocked processing.
The safety device of the utility model electric automobile charging pile charging port is simple in structure, easily assembling; Driving mechanism is small-sized stepping motor, and energy consumption is little, and has speed-regulating function, can make door switching process medium velocity moderate; By being installed in two infrared reflections on the charging pile inwall near the switch of the switch sensor feedback door signal that puts in place, realize the accurate control of door; The motion state of Hall element and magnet feedback door can be handled door and run into the situation of blocking charging plug or other article at the volley, realizes the automatic control function in the door motion, and is safe and reliable.
