The safe and reliable electric automobile DC charging rifle of the present invention, concrete operating principle are as follows：
During original state, main auxiliary catch 5 is in horizontality in charging gun, and main auxiliary catch fastens gib head 11 and thumb-button push rod
Gib head 12 is in buckling state, and the first spring 19 is in nature compressive state；Because auxiliary detection arm 24 position is compared with thumb-button push rod
Rearward, then it is not at buckling state to gib head 12, and the 3rd spring 29 is in nature compressive state, and second spring 22 is in compression shape
State.
When charging gun inserts charging socket, the top of socket can push up upwards first holds main auxiliary catch gib head 8, and now first
Spring 19 is in compressive state, and main auxiliary catch fastens gib head 11 and moved downward, after reaching certain distance, with thumb-button push rod gib head 12
Separation, the elastic force of the second spring 22 of compressive state rearward push thumb-button push rod 16 open, until reaching nature retracted position.By
Position is plugged together in the presence of a groove coordinated with main auxiliary catch gib head 8 in charging socket, when insertion continues to reach concave part
During position, the main auxiliary catch gib head 8 lifted can be in the case where the first spring 19 compress caused elastic force effect around main 9 turns of auxiliary catch bearing pin
It is dynamic, the trend moved downward is produced, is pressed into socket recess.Now, the first bullet 19 is changed into nature compressive state, main auxiliary catch 5
In horizontality, thumb-button push rod rebounds backward.It can be charged under such a state, that is, charge SBR, when starting to fill
When electric, because for controlling actuating unit 13 and circuit that block body brake axle 31 acts while being connected, block body brake axle 31 is powered
Work, extending action is carried out, keeps off before button beats push rod block body 30, prevents it from travelling forward.Due to button when now charging
14 are integrated with thumb-button push rod 16, thumb-button push rod block body 30, can not move, then prevent the action of charging gun, main insurance
The buckle status of hook gib head 8, charging gun can not be extracted, and now charging gun is safe condition, when ensure that charging charging gun not by with
Meaning is extracted.
When charging, which finishes, to be needed to extract charging gun, power operation is carried out first, is now used to control block body brake axle
The stopping of actuating unit 13 action of 31 actions, block body brake axle 31 are retracted, and thumb-button push rod block body 30 can be acted freely forwards.
Press button 14 with hand, button 14 advances, and thumb-button push rod jacking block 15 can push up the pushing tow bearing pin 10 of main auxiliary catch, if continue by
Under, then pushing tow bearing pin 10 can with produce downward motion under the ramp effect of thumb-button push rod jacking block 15, compress the first spring 19,
Now it can be seen from aforesaid operating principle, main auxiliary catch gib head 8 can produce the trend moved upwards, when button 14 continues to promote,
Main auxiliary catch gib head continues to lift, until button is advanced to when can not move forward, main auxiliary catch gib head 8 can be from filling
Extracted in electrical socket groove, at this point it is possible to which charging gun handle is gone out.Due to being in artificial before the first spring 19 when extracting charging gun
Compressive state, nature compressive state can be now returned to, then main auxiliary catch 5 is changed into keep level, release button 14, thumb-button push rod
16 can rebound backward in the presence of second spring.Detained again until thumb-button push rod gib head 12 fastens gib head 11 with main auxiliary catch
Close, revert to the original state of charging.

When row extracts operation, if because operational error causes main auxiliary catch gib head 8 in being left from charging socket groove, but water is not kept
Button unclamps during state usually, and now main auxiliary catch fastens gib head 11 and is in downward position, can not be with thumb-button push rod gib head
12 buttons are complete, and button 14 may directly rebound rearmost position, and can not be returned to original state, influence operation next time.Root
Understood according to aforesaid operating principle, main auxiliary catch detection gib head 26 produces downward pressure to auxiliary detection arm gib head 25 during this state
Power, and then compression is produced to the 3rd spring so that when button 14 rebounds backward, main auxiliary catch detection gib head 26 detects with auxiliary
Arm gib head 25 keeps fastening, it is therefore prevented that button 14 rebounds completely.Now, then carry out again button 14 is pressed into operation, you can
Return to normal condition.
Another effect that the main auxiliary catch of the present invention fastens gib head 11 is to detect the state of wear of main auxiliary catch gib head 8,
When the abrasion of main auxiliary catch gib head 8 reaches to a certain degree, after charging insertion socket, main auxiliary catch fastens gib head 11 and thumb-button push rod
Gib head 12 can not be completely disengaged, and now, button 14 is unable to resilience, and the state of resilience is unable to by button 14 and can detect main guarantor
