Emergent entrance hole.
As a kind of preferred version, in the locking-unlocking device of described charging plug, described reducing motor is straight
Stream reducing motor.
The beneficial effects of the utility model are:This utility model passes through to arrange reducing motor and clamping block, in charging plug
Insertion charging socket, after starting to charge up, reducing motor drives clamping block to rotate so that on clamping block near the direction of locking bar
Locking boss is located at the lower section of locking bar, thus cannot press locking bar, thus ensure that in charging process, charging plug and charging
Socket is in the state of being reliably connected all the time, will not interrupt charging process because of accidental unlocking.Further, since having installed locking fine motion additional
Switch, and the pushing guiding face seamlessly transitting from shallow to deep is provided with clamping block, on the one hand, avoid because clamping block is to lock
The damage determined the pushing of microswitch and cause, thus extending the service life of locking microswitch, on the other hand, locking is micro-
Dynamic switch can perceive whether clamping block is rotated in place so that the control of charging control circuit is safe and reliable;In addition, due to
Install detection microswitch additional, whether locking bar is depressed so that the control of charging control circuit is more pacified such that it is able to perceive
Entirely reliable.

Specific embodiment
Below in conjunction with the accompanying drawings, describe a kind of the concrete of locking-unlocking device of charging plug described in the utility model in detail
Embodiment:
As shown in Figure 1, Figure 2 and Figure 3, the locking-unlocking device of charging plug described in the utility model, its structure includes
Have:Shell 1, be arranged in shell 1 be made up of back box 22 and cover box 21 dispose box 2 and being movably articulated on shell 1
Locking bar 3, the front end of locking bar 3 is provided with grab 31, is provided with Lock spring 6 between the rear portion of described locking bar 3 and shell 1, disposes
It is provided with DC speed-reducing 4, the clamping block 5 being arranged on the output shaft of DC speed-reducing 4 is matched with clamping block 5 in box 2
Close locking microswitch 7, can detect whether locking bar 3 is in the detection microswitch 8 of locking state, on described clamping block 5
It is provided with locking boss 51, described disposing offers the pressing peace matching with the pressing lever detecting in microswitch 8 on box 2
Put hole and the locking spacing hole matching with locking boss 51, described locking boss 51 is from the locking spacing hole disposing box 2
In stretch out, the pressing lever in described detection microswitch 8 from dispose box 2 pressing placement hole stretch out, and, detect fine motion
Pressing lever in switch 8 and described locking boss 51 are respectively positioned on the pin joint of locking bar 3 and shell 1 and described Lock spring 6
Between, as shown in figure 4, be provided with described clamping block 5 can be by gentle for the pressing lever in locking microswitch 7 inwardly pushing
Push guiding face 521, a kind of concrete set-up mode of this pushing guiding face 521 is:Offer on clamping block 5 and lock fine motion and open
Close the circular arc guide groove 52 that matches of pressing lever in 7, the surface of this guide groove 52 diapire seamlessly transits from shallow to deep,
Form described pushing guiding face 521;In the present embodiment, a kind of concrete set-up mode of described Lock spring 6 is:Described lock
Locking bar placement seat 32 is provided with the rear portion bottom surface of bar 3, the arrangement box 2 in described shell 1 is provided with placement seat in shell, should
In shell, placement seat is involuted by half placement seat 212 in half mounting seat 222 and cover box 21 in back box 22, described locking bar
Lock spring 6 is faced on placement seat in placement seat 32 and shell and is respectively arranged with arrangement blind hole, Lock spring 6 is strapped in locking bar peace
Put in the arrangement blind hole on this pair of placement seat of placement seat in seat 33 and shell;Offer on the cover box 21 of described arrangement box 2 with
The corresponding emergent solution lockhole 211 of described locking boss 51, described shell 1 offers and this emergent solution lockhole 211 phase
The corresponding emergent entrance hole 11 needing could be inserted with specific purpose tool.
Work process of the present utility model is:After charging plug inserts charging socket and puts in place, the lock on charging plug
Bar 3 lean forward in the presence of Lock spring 6 so that the grab 31 of locking bar 3 front end fall into charging socket bayonet socket in, charge control
Circuit passes through to detect that microswitch 8 can perceive after locking bar 3 locked, by the positive power supply of DC speed-reducing 4 so that
The output shaft of DC speed-reducing 4 rotates, goes to locking boss 51 lower section of locking bar 3 with clamping block 5 towards locking bar 3, this
So that locking bar 3 keeps lock-out state, after locking boss 51 goes to position, pushing guiding face 521 will lock Shi Wufa pressing locking bar 3
The pressing lever of microswitch 7 inwardly also shifts position onto, after charging control circuit obtains the signal that puts in place of locking microswitch 7, starts
Charge;After charging terminates, charging control circuit disconnects charge circuit, then, by DC speed-reducing 4 reverse power supply, making
The output shaft obtaining DC speed-reducing 4 rotates away from the direction of locking bar 3 with clamping block 5, and such locking bar 3 is just departing from lock
Determine the control of boss 51, press locking bar 3 rear portion, so that the front portion of locking bar 3 is lifted, then, charging plug is dialled from charging socket
Go out.
In sum, preferred embodiment only of the present utility model, is not used for limiting this utility model enforcement
Scope, the impartial change that shape described in all right according to this utility model, construction, feature and spirit are made with repair
Decorations, all should be included in right of the present utility model.
