Specifically, referring to fig. 1 to 3, the charging pile 10 with a boom type gun line movement assisting mechanism of the present embodiment includes a chassis 100 for providing a charging power source and a gun line movement assisting mechanism 200 rotatably disposed on a top plate of the chassis 100, wherein an inner cavity of the chassis 100 is provided with a power conversion device and a liquid cooling device electrically connected with an external power source, an output end of the power conversion device is connected with a gun line penetrating through a housing of the chassis 100, a gun head for providing a charging connector of a vehicle is disposed at an end of the gun line, and a gun seat for plugging and fixing the gun head is disposed on an outer surface of the housing of the chassis 100. In addition, in actual use, the casing surface of the case 100 may be provided with a card reader, a touch screen, a charging pile operation indicator light, and other components.

The gun line moving booster mechanism 200 comprises an adapter plate 210 fixed on the top plate of the chassis 100, a sliding base 220 rotatably sleeved on the adapter plate 210, a guide rail 230 fixed at the bottom of the sliding base 220 and extending in the same direction as the sliding base 220, a sliding block 240 slidably mounted on the guide rail 230, and a gun line restraining assembly 250 fixed on the sliding block 240 and used for fixing the tail end of a gun line, wherein the level of the matching part of the sliding base 220 and the adapter plate 210 is lower than that of the free end of the sliding base 220. It can be also understood that the sliding base 220 is obliquely arranged relative to the horizontal direction, when the charging pile is idle, the gun head is inserted into the gun seat, and the gun wire is lifted on the gun wire constraint assembly 250, in this case, due to the oblique arrangement of the sliding base 220, the sliding block 240 slides towards the direction close to the connection part of the sliding base 220 and the adapter plate 210 under the action of gravity, so as to drive the gun wire between the gun wire constraint assembly 250 and the gun head, which is extracted during the charging process, to be pulled towards the case 100, and the gun wire stretches or lifts, thereby changing the center of gravity of the whole gun wire, and avoiding the problem of damage to the sliding base 220 caused by overlarge acting force from the gun wire on the tail end of the sliding base 220; meanwhile, the movement straightening of the gun line can also avoid the gun line from mopping, so that the gun line is protected.
