The main supporting portion 3442b may be a plurality of supporting bars, and when the supporting bars are the same, the plurality of supporting bars are circumferentially arranged to support the main reel 3442a.

When the winding drum 342 rotates, the main winding drum 3442a rotates along with the winding drum 342, the conductive carbon brush 3442c rotates along with the main slip ring 344, and the conductive carbon brush 3442c is always electrically connected with the conductive ring 3441b and the conductive ring 3441b is electrically connected with the conductive rod 3441d, so that the conductive carbon brush 3442c is always electrically connected with the conductive rod 3441 d.

Specifically, the winding drum 342 includes a winding disc 3421 and a winding portion 3422, the winding disc 3421 is rotatable about its own axis by an external force, and the winding portion 3422 extends axially from the disc surface of the winding disc 3421 to wind the charging gun wire 330. It should be noted that, the winding portion 3422 may have a barrel-like structure or a rod-like structure, and specifically, the winding portion 3422 may have a plurality of winding rods circumferentially arranged.

The number of the winding discs 3421 may be one or two, and in the embodiment of the present utility model, the number of the winding discs 3421 is two, and the two winding discs 3421 are disposed opposite to each other.

Because the power end 342a and the outgoing end 342b are disposed opposite to each other, the signal section 3321 and/or the power section 3322 that are drawn out from the outgoing end 342b do not easily enter between the driving mechanism 347 and the power end 342a, thereby reducing the occurrence of accidents.

In some embodiments of the present utility model, to simplify the structure of the driving connection of the power end 342a and the driving mechanism 347, the power end 342a includes an annular gear; the drive mechanism 347 is in driving engagement with the ring gear by means of a set gear.

Further, the inner gear ring is opposite to one end of the power section 3322 and the signal section 3321, so that the power end of the charging gun wire 330 winding and unwinding device is opposite to the power section 3322 and the signal section 3321.

Thereby enabling the router 348 to adjust following the change in the axial position of the charging gun wire 330.

The first direction X1 and the second direction X2 are opposite directions and are substantially parallel to the axial direction of the winding drum 342. The winding direction S and the paying-off direction F are opposite directions, and when the winding direction S rotates, the winding drum 342 performs winding operation; the winding drum 342 performs a paying-off action while rotating in the paying-off direction F.

The drive connection of the wiring device 348 to the power end 342a may be a gear drive connection, a chain drive connection, a belt drive connection, etc. Taking a chain drive connection as an example, the router 348 includes a router main body 3481 and a driving member 3482, wherein the router main body 3481 is disposed at a moving end of the driving member 3482, the driving member 3482 is provided with a first sprocket, the corresponding power end 342a is provided with a second sprocket, and the chain bypasses the first sprocket and the second sprocket to drive.

In some embodiments of the present utility model, the driving member 3482 may be a screw-nut mechanism, including a screw and a nut rotatably disposed on the screw, where the first sprocket is fixed to the screw. The above is only one implementation way to achieve the conversion of the rotational motion of the power end into the linear motion of the router, as long as the transmission member 3482 capable of achieving the conversion of the rotational motion into the linear motion of the router body 3481 is within the scope of the present utility model.

In addition, the wiring device 348 and the winding drum 342 share one driving mechanism 347, so that the structure of the charging gun wire transceiver 340 can be simplified, the energy loss can be reduced, and the product cost can be reduced. Through adjusting the size and the number of teeth of the first sprocket and the second sprocket, the moving speed of the wiring device 348 can be adjusted, and the charging gun wire receiving and transmitting device 340 can prevent the charging gun wire 330 wound on the winding drum 342 from being too tight or too loose when the charging gun wire is wound on the winding drum 342, so that the service life of the charging gun wire 330 is prolonged.
