a cable spiral winding path constraint roller 16 at the uppermost end of the roller spiral array along the spiral path is recorded as a head end constraint roller 16.1; a cable spiral winding path constraint roller 16 at the lowest end of the spiral path of the roller spiral array is marked as a tail end constraint roller 16.2, and the tail end constraint roller 16.2 is positioned right above the cable falling hole 8; one side of the head end constraint roller 16.1 is rotatably provided with an upper auxiliary wheel 25 through an upper roller wheel bracket 01, one side of the tail end constraint roller 16.2 is rotatably provided with a lower auxiliary wheel 26 through a lower roller wheel bracket 02, and the structures of the upper auxiliary wheel 25 and the lower auxiliary wheel 26 are the same as the structure of the cable spiral winding path constraint roller 16; the junction of the fourth section 9.4 of the charging cable and the fifth section 9.5 of the charging cable is clamped between the head end constraint roller 16.1 and the upper auxiliary wheel 25, and the junction of the third section 9.3 of the charging cable and the fourth section 9.4 of the charging cable is clamped between the tail end constraint roller 16.2 and the lower auxiliary wheel 26;

the upper roller bracket 01 and the lower roller bracket 02 are both fixed on the roller shaft spiral bracket 14.

The clutch 39 includes a locked state in which the output shaft 38 is coaxially synchronized with the annular inner edge 37, and a released state in which the output shaft 38 and the annular inner edge 37 are free to rotate relative to each other when the clutch 39 is in the locked state.

The central motor 13 is a brake type stepping motor.

The cylinder outer wall 1.1 of the rotary cylinder 1 is a rubber coating for increasing friction.

The working principle and the working method of the invention are as follows:

the working method of the charging cable hiding system of the new energy automobile charging pile is as follows:

state of the device in non-use state:

the second section 9.2 of the charging cable in the cable storage bin 10 is in a zigzag and bent loose state, and at this time, the sixth section 9.6 of the charging cable is in a shortest state, at this time, any part of the sixth section 9.6 of the charging cable is not exposed outside the machine body shell 20, so that the charging gun 3 at this time can stably abut against the cable hider shell 17 at the position of the cable through hole 18 without depending on a conventional charger seat, at this time, the clutch 39 is in a locked state, and the central motor 13 is in a braking state, so that the revolving cylinder 1 at this time is in a locked state, and further, all the cable spiral winding path restricting rollers 16 are in a locked state under the effect of static friction force, so that the fourth section 9.4 of the charging cable which is wound on the roller spiral array formed by the plurality of cable spiral winding path restricting rollers 16 along the spiral path is completely locked under the main effect of static friction, therefore, the user immediately pulls the charging gun 3 hard, the length of the sixth section 9.6 of the charging cable cannot be changed, and the locking effect on the charging gun 3 is realized; particularly, when the charging pile is in a maintenance state, a user can be prevented from taking the charging gun 3 with a fault forcibly, so that safety risk is caused;

user access charging gun 3 method:

after a user obtains authorization of using the charging pile, the clutch 39 is controlled to be in a disengaged state, the output shaft 38 and the annular inner edge 37 can freely rotate relatively, so that the rotary cylinder body 1 is in a free state, the user holds the charging gun 3 to pull outwards to prepare for charging on an automobile, at the moment, the fourth section 9.4 of the charging cable can drive all the cables on the roller spiral array to synchronously and passively rotate along the spiral winding path constraint rollers 16 under the action of the pulling force of the user, meanwhile, the reaction force of the plurality of cable spiral winding path constraint rollers 16 on the fourth section 9.4 of the charging cable can form a certain damping effect on the pulling force of the user, and if the user is loose, the rotary cylinder body 1 can adaptively rotate, the sixth section 9.6 of the charging cable can be gradually lengthened in the process, the second section 9.2 of the charging cable which is bent and loosened can be gradually shortened, when the second segment 9.2 of the charging cable in the winding, bending and relaxing state is gradually shortened to be straightened, the sixth segment 9.6 of the charging cable is in the longest state, and the length of the sixth segment 9.6 of the charging cable exposed outside the machine body shell 20 is the longest length;

method of re-hiding the sixth section 9.6 of the charging cable exposed outside the body casing 20:

after the user has finished charging, the sixth section 9.6 of the charging cable exposed outside the machine body shell 20 needs to be concealed again, at this time, the clutch 39 is controlled to be locked, at this time, the output shaft 38 and the annular inner edge 37 are coaxially synchronous, the central motor 13 is controlled to make the rotary cylinder 1 actively rotate anticlockwise along the axis in the top view, further, all cable spiral winding paths on the roller spiral array restrict the roller 16 to actively rotate clockwise along the axis in the top view, the fourth section 9.4 of the charging cable is gradually fed downwards along the spiral path of the fourth section 9.4 under the driving of clockwise rotation of the plurality of cable spiral winding path restricting rollers 16, so that the sixth section 9.6 of the cable is gradually pulled inwards from the cable through hole 18, and the second section 9.2 of the charging cable in the stretched state is gradually restored to the bent relaxed state, and the fourth section 9.4 of the charging cable is gradually fed downwards along the spiral path of the fourth section 9.4 of the charging cable, until now, no part of the sixth section 9.6 of the charging cable is exposed outside the machine body shell 20, and the sixth section 9.6 of the charging cable is in the shortest state, and because the plurality of cable spiral winding paths restrict the idler wheel 16 to have certain damping, the charging gun 3 can stably abut against the cable hiding device shell 17 at the position of the cable through hole 18 without depending on a traditional charger seat.

The above is only a preferred embodiment of the present invention, and it should be noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the invention, and are intended to be within the scope of the invention.
