Description

Technical Field

[0001] The utility model relates to the technical field of winding structure devices, in particular to a charging stack winding structure. Background Art

[0002] With the development of electric vehicles, the demand for charging is also growing. Charging piles and charging posts are both common charging devices, but charging posts are one post and one gun. A charging post has only one charging gun and poor compatibility. It cannot charge cars with different power requirements. Charging piles are one post and multiple guns. They have multiple charging guns and have certain compatibility. They can charge cars with different power requirements. Therefore, the development prospect of charging piles is much greater than that of charging posts. In order to facilitate charging, the charging cable connecting the charging pile to the charging gun has a certain length. When not in use, the charging cables are all exposed to the outside. There is a lack of a certain charging cable winding protection structure, and the charging cables are easily damaged.

[0003] For example, a charging stack winding structure with announcement number CN221216713U includes a winding assembly, wherein the winding assembly includes a protective cylinder, a winding shaft, a motor and a winding ring, one end of the protective cylinder is provided with a through hole, one end of the winding shaft is fixedly passed through the other end of the protective cylinder, one end of the winding shaft is provided with a through groove, the through groove is connected with the interior of the protective cylinder, the motor is fixedly connected with the interior of the protective cylinder, the winding ring is rotationally connected with the protective cylinder, the winding ring is transmission-connected with the output end of the motor, the winding ring and the winding shaft are correspondingly arranged, a connecting plate is provided at the end of the protective cylinder away from the through hole, a through opening is provided in the center of the connecting plate, and a connecting hole is provided on the plate body of the connecting plate.

[0004] The above-mentioned device mainly drives the winding ring through a motor to loosen and wind up the charging cable, which can protect the charging cable from damage and increase its service life. However, its design is slightly flawed. The winding ring is designed to be longitudinally oriented. This design may cause the charging cable to be torn due to different force transmission directions when loosening or winding, and in severe cases, the outer protective layer of the charging cable may be damaged. In addition, there is no partition on the winding shaft when winding and loosening, which makes it easy for the charging cable to accumulate and entangle. Utility Model Content

[0005] The purpose of the utility model is to provide a charging stack winding structure to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A winding structure for a charging stack, including a bottom plate, an external housing is installed at the upper end of the bottom plate, and a top cover plate is assembled at the upper end of the external housing. There are curved corners at the edge of the top cover plate, and an insertion opening is provided on the surface of the top cover plate. An inner edge block is installed on one side of the insertion opening, and a pressing block is installed beside the inner edge block. There is a recessed layer beside the pressing block, and a connecting plate is assembled inside the recessed layer. An external plate is installed on the upper surface of the connecting plate, and a winding shaft is installed inside the external housing;

[0007] The inner surface of the external housing is provided with an inner concave layer, and there are concave openings at the upper and lower ends of the inner concave layer. Rotating columns are installed on the concave openings;

[0008] The outside of the rotating column is connected to a bearing block, and a transmission shaft is installed at the upper end of the bearing block. A rotating machine is connected to the upper end of the transmission shaft;

[0009] A support plate is assembled beside the rotating machine, and a connecting rod is assembled at the front end of the bearing block. A winding ring is installed at the front end of the connecting rod.

[0010] Preferably, there is a through opening at the front end of the winding ring, and a rotating column is assembled in the middle of the through opening. Rotating clamping arms are assembled on the surface of the rotating column.

[0011] Preferably, fixing bolts are installed at both ends of the rotating clamping arm.

[0012] Preferably, spiral attachment blocks are installed on the outer surface of the winding shaft.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] 1. Compared with other winding structures of charging stacks, this device improves the internal winding ring. The orientation of the winding ring itself is designed as a horizontal orientation opening. This design makes it impossible to tear the charging cable when loosening or winding the charging cable. In addition, most winding rings require the charging cable to be inserted through the winding ring first when in use. This device designs a rotating arm on the outside to facilitate the insertion of the charging cable.

[0015] 2. In addition, the surface of the winding shaft assembled in the middle of the device is provided with spiral attachment blocks. The design of the spiral attachment blocks enables the charging cable to wind along the bottom layer during winding, avoiding the phenomenon of accumulation and entanglement. There is an outward convex edge at the outer end of the spiral attachment block, which allows the charging cable to be smoothly pulled out when loosening. BRIEF DESCRIPTION OF THE DRAWINGS
