Description

Technical Field

[0001] The utility model belongs to the technical field of charging piles, and particularly relates to a wire-retracting and -releasing mechanism of a charging pile. Background Art

[0002] New energy electric vehicle charging piles mainly include charging pile bodies, charging cables, charging guns, etc. The charging cables connect the charging pile bodies and charging guns. In order to adapt to the size of electric vehicles and the different positions of charging ports, longer charging cables are generally reserved to ensure the range of the charging gun.

[0003] At present, some charging piles are equipped with a wire-retracting device. For example, the Chinese patent with the authorization announcement number CN220764135U discloses a new energy charging pile with a charging cable that can be quickly folded and retracted. The handle rotates the turntable, which drives the winding shaft to rotate, thereby reeling the charging cable. Figure 2 It can be seen that when the portion of the charging cable connected to the charging gun is reeled in by rotating the winding shaft, the portion of the charging cable connected to the charging pile will be released from the winding shaft, causing problems such as failure to retract the charging cable and affecting the retracting effect of the charging cable. Therefore, it is urgent to study a charging pile retracting and releasing mechanism to solve the above problems. Utility Model Content

[0004] The utility model provides a wire-retracting and -releasing mechanism for a charging pile, and its purpose is to solve the technical problems raised in the above-mentioned background technology.

[0007] As a preferred technical solution of the utility model, a convex ring is coaxially fixed to the upper edge of the second through hole; a movable ring for inserting the charging cable is coaxially arranged on the inner side of the convex ring; the movable ring and the convex ring are connected by multiple tension springs.

[0008] As a preferred technical solution of the utility model, the surround drive assembly includes a rotating cylinder rotatably sleeved on the lower part of the load-bearing shaft; the circumferential outer wall of the rotating cylinder is radially fixed with mounting strips for carrying the lifting assembly; the lower fixed sleeve of the rotating cylinder is provided with a worm gear; a worm is meshed on the worm gear; one end of the worm passes through the side wall of the protective barrel and is fixed with a handle; the worm is rotatably connected to the side wall of the protective barrel.

[0009] As a preferred technical solution of the utility model, the lifting assembly includes a screw rod vertically rotatably connected to the mounting strip; the screw rod is arranged on one side of the retracting roller; the screw rod is threadedly matched with a screw sleeve; a lifting block for carrying the wiring harness guide assembly is fixed on the screw sleeve; a sliding sleeve is vertically fixed and inserted on the lifting block; a guide rod is slidably inserted in the sliding sleeve; the lower end of the guide rod is fixed on the mounting strip; the lower end of the screw rod is fixed with a gear; an inner gear ring is meshed on the gear; the inner gear ring is horizontally fixed on the inner side surface of the protective barrel.

[0011] The utility model has the following beneficial effects:

[0012] The utility model fixes the charging cable through the first through hole, the wire threading channel and the wire harness positioning hole, and fixes the charging cable through the wire harness positioning hole, and passes the part of the charging cable connected to the charging gun through the second through hole and the wire harness guide assembly and is wound around the outer periphery of the retracting roller. When the charging cable needs to be wound, the lifting assembly is driven by the surrounding driving assembly to make a positive circular motion around the retracting roller, and the lifting assembly is used to drive the wire harness guide assembly to move upward, so that the wire harness guide assembly winds the charging cable around the retracting roller. When the charging cable needs to be released, the lifting assembly is driven by the surrounding driving assembly to make a reverse circular motion around the retracting roller, and the lifting assembly is used to drive the wire harness guide assembly to move downward, so that the wire harness guide assembly releases the charging cable from the retracting roller, thereby effectively improving the efficiency and effect of retracting and releasing the charging cable.
