Description

Technical Field

[0001] This invention belongs to the field of new energy charging pile technology, specifically relating to a new energy charging pile wiring device and method. Background Technology

[0002] Charging piles function similarly to gas pumps at gas stations. They can be fixed to the ground or walls and installed in parking lots or charging stations in public buildings and residential areas. They can charge various models of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. Traditional charging piles often have a distance between the parking location and the charging pile, so the charging cable is designed with an extension to accommodate charging needs at different locations. However, traditional charging cables tend to be messy when extended and inconvenient to reel in.

[0003] To address this, patent specification CN114454752B discloses a new energy charging pile cable routing device, including a fixed shell and a sliding groove. The sliding groove is located on one side of the fixed shell, and a winding mechanism is rotatably connected inside the fixed shell. A drive mechanism is fixedly installed inside the fixed shell outside the winding mechanism, and a cable is wound around the outer surface of the winding mechanism. This new energy charging pile cable routing device allows the cable to move outward by pulling the pull ring. During this movement, the sliding sleeve moves through the contact of the top teeth and locking teeth, and engages with the positioning hole through the top bead. When the cable is pulled parallel to the charging position, pulling the connector causes the inner fixed sleeve to move outward, connecting the charging gun (connected to the battery cell) to the vehicle, initiating charging. The cable is discharged outward along the sliding groove and supported by the sliding sleeve at a certain distance, thus keeping the cable neat.

[0004] However, the aforementioned new energy charging pile cable routing device has shortcomings in use. First, its cables are wound vertically in a flat plane, resulting in a relatively short cable length that can be wound up, which is not conducive to meeting the charging needs of parking spaces on both sides of the charging pile. Second, it cannot automatically clean the cable surface after each use. Therefore, it needs to be optimized and improved. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned problems existing in the prior art and to provide a new energy charging pile wiring device and method.

[0006] To achieve the above-mentioned technical objectives and effects, the present invention is implemented through the following technical solution:

[0007] This invention provides a new energy charging pile cable laying device, which includes a cable laying box and a power box. The cable laying box is equipped with a winding roller, a dust cover, a reciprocating lead screw, a guide rod, a multi-functional cable laying block, and a drive motor. The power box is equipped with a first belt drive and a second belt drive. The winding roller consists of a roller shaft and baffles on both sides. A cable is spirally wound on the outer side of the roller shaft. The inner end of the cable is connected to the new energy charging pile body through a conductive slip ring and an external wire. A charging gun is installed on the outer end of the cable. The reciprocating lead screw and the guide rod are threaded through the multi-functional cable laying block. A dust cover is sleeved on the outer side of the multi-functional cable laying block. A portion of the cable passes through the dust cover and the multi-functional cable laying block. The drive motor is located above the outer periphery of the dust cover. The output shaft of the drive motor is connected to the reciprocating lead screw through the first belt drive, and the reciprocating lead screw is connected to the roller shaft of the winding roller through the second belt drive.

[0008] Furthermore, in the aforementioned new energy charging pile wiring device, the wiring box is an open box. The two side plates of the wiring box are symmetrically provided with a first rotating hole to facilitate the rotation of the roller shaft in the winding roller, a second rotating hole to facilitate the rotation of the reciprocating screw, and a fixing hole to facilitate the fixed installation of the guide rod. One side plate of the wiring box is provided with a through-shaft hole to facilitate the output shaft of the drive motor to pass through. The bottom plate of the wiring box located inside the dust cover is provided with a dust collection hole.

[0009] Furthermore, in the aforementioned new energy charging pile wiring device, the winding roller has a lead groove near one end of the roller shaft to facilitate the lead-out of the inner end of the cable from the first rotating hole.

[0010] Furthermore, in the aforementioned new energy charging pile cable routing device, the dust cover includes an irregularly shaped plate portion and a vertical plate portion. The inner cavity surface of the irregularly shaped plate portion is in contact with the upper part of the multi-functional cable routing block. The lower ends of the irregularly shaped plate portion are respectively provided with vertical plate portions perpendicular to the bottom plate of the cable box. A first cable through hole is opened on one side of the irregularly shaped plate portion, and a first cable box brush is installed at the first cable through hole. A second cable through hole is opened on the other side of the irregularly shaped plate portion, and a second cable box brush is installed at the second cable through hole.

[0011] Furthermore, in the aforementioned new energy charging pile cable routing device, the multifunctional cable routing block includes a cable routing block body. Near the center of the cable routing block body is a lead screw hole that mates with a reciprocating lead screw and a guide hole that mates with a guide rod. Near the periphery of the cable routing block body is an annular cable-passing groove. Around the periphery of the annular cable-passing groove, the cable routing block body has a dust collection groove. Near the first cable through-hole, the cable routing block body has a first cable inlet / outlet. Near the second cable through-hole, the cable routing block body has a second cable inlet / outlet. A first support ring and a second support ring are fixed to the portion of the cable routing block body near the second cable inlet / outlet in the annular cable-passing groove. A cleaning ring is movably supported between the first and second support rings. A cleaning motor is installed in the center of the cable routing block body, and a drive gear for rotating the cleaning ring is installed at the output end of the cleaning motor.

[0012] Furthermore, in the above-mentioned new energy charging pile wiring device, the cross-sectional shape of the annular wire-threading groove matches the cross-sectional shape of the cable, the width of the ash-collecting groove is less than the diameter of the cable, and the diameters of the first cable inlet and outlet and the second cable inlet and outlet are greater than or equal to the diameter of the cable.

[0013] Furthermore, in the aforementioned new energy charging pile cable routing device, the cleaning ring includes a cleaning ring body, with positioning protrusions at both ends of the cleaning ring body. The first support ring and the second support ring are respectively provided with positioning ring grooves that cooperate with the positioning protrusions. The outer side of the cleaning ring body is evenly distributed with driven protrusions that cooperate with the drive gear. The inner surface of the cleaning ring body is evenly distributed with cleaning protrusions for cleaning the cable surface. The cleaning ring body is provided with several radial ash discharge channels, and the positions of the radial ash discharge channels are staggered from the positions of the cleaning protrusions.

[0014] This invention also provides a method for wiring new energy charging piles, based on the aforementioned new energy charging pile wiring device, comprising the following steps:

[0015] 1) When the cable needs to be pulled out, the drive motor rotates in the forward direction, the winding roller rotates accordingly and releases the cable. At the same time, the multi-functional cable laying block moves back to the starting position under the drive of the reciprocating screw. The position of the multi-functional cable laying block and the position of the cable being pulled out are matched to achieve anti-pull.

[0016] 2) When the cable needs to be retracted, the drive motor rotates in the opposite direction, and the winding roller rotates accordingly to retract the cable. At the same time, the multi-functional cable laying block moves back and forth under the drive of the reciprocating screw. The position of the multi-functional cable laying block and the winding position of the cable are matched to achieve spiral winding of the cable. During the cable retraction process, the cleaning motor in the multi-functional cable laying block is activated, and the cleaning ring is driven to rotate by the drive gear. The cleaning ring removes dust from the surface of the cable inside.

[0017] The beneficial effects of this invention are:

[0018] This invention provides a new energy charging pile cable laying device, which mainly consists of a cable laying box, a power box, a winding roller, a dust cover, a reciprocating lead screw, a guide rod, a multi-functional cable laying block, a drive motor, a first belt drive component, and a second belt drive component. These components work together to utilize the axially arranged cable laying box for multi-layer spiral winding of cables, allowing for the winding of shorter cable lengths to meet the charging needs of parking spaces on both sides of the charging pile. Simultaneously, the multi-functional cable laying block provides anti-pull protection during cable laying, spiral winding traction during cable winding, and dust removal from the internal cable surface during winding.

[0019] Of course, any product implementing this invention does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description
