Description

Technical Field

[0001] This utility model belongs to the field of new energy vehicle charging pile technology, and in particular relates to a new energy vehicle charging pile with a cable winding device. Background Technology

[0002] New energy vehicle charging stations are infrastructure devices specifically designed to provide power replenishment for electric vehicles. Their core function is to safely and efficiently transmit electrical energy from the power grid or energy storage system to the electric vehicle's power battery. As a key hub connecting the power grid and electric vehicles, modern charging stations have evolved into intelligent power replenishment devices integrating power conversion, safety protection, human-machine interaction, and data communication. The charging station system mainly consists of core components such as a power supply module, control unit, charging interface, metering system, and safety protection devices. Through power electronics technology, it achieves AC / DC conversion and power regulation to meet the charging needs of different types of electric vehicles.

[0003] In practical use, charging stations for new energy vehicles often require long charging cables to meet the needs of various charging scenarios due to differences in the location of charging ports for different vehicle models and variations in parking distances. While this design improves the convenience and adaptability of charging, it also brings a series of practical problems during use.

[0004] When the charging cable is too long, it is inevitable that the cable will droop and drag on the ground during the charging process. Especially in outdoor charging scenarios, the continuous friction between the cable and various ground materials will gradually cause wear and tear on the outer insulation material. This wear and tear not only affects the appearance of the cable, but more importantly, it will reduce its insulation performance and safety level. Long-term accumulation may lead to damage to the cable's protective layer, thereby causing safety hazards.

[0005] Meanwhile, the charging cable on the floor is constantly in contact with the ground, easily accumulating mud and water in rainy weather and dust and sand in dry environments. These impurities not only cause poor contact at the charging interface, affecting charging efficiency, but also accelerate the oxidation and corrosion of the connector's metal components. Even more problematic is that in cold winter regions, the surface of the charging cable is prone to ice and snow accumulation, increasing the difficulty of cable reeling in and out. Furthermore, when used near industrial areas or construction sites, the cable surface may also be contaminated with oil or chemicals, all of which can cause varying degrees of corrosion to the cable material.

[0006] In addition, the phenomenon of cables dragging on the ground will cause users to frequently bend over to tidy up the cables during operation, which will reduce the user experience. Especially at night or in bad weather conditions, the messy cable layout may also become a safety hazard, which may easily cause people to trip and fall. Utility Model Content

[0036] Please see Figures 1 to 7 The present invention provides two embodiments:

[0037] Example 1: A new energy vehicle charging pile with a cable retraction device, comprising:

[0038] The charging pile body 6 is equipped with a charging cable 5. A bracket 3 is fixed at one end of the charging pile body 6. A round box 4 is set on the bracket 3. A turntable 21 is rotatably installed on the side of the round box 4. A motor 8 is also set on the bracket 3, and the drive end of the motor 8 is connected to the turntable 21.

[0039] Brush rollers 25 are provided on both the top and bottom of one end of the turntable 21. The end of the charging cable 5 away from the charging pile body 6 passes through one side of the round box 4 and enters the round box 4. After passing through the two brush rollers 25, it comes out from the other side of the round box 4. The end of the charging cable 5 away from the charging pile body 6 is connected to a charging head.

[0040] The charging cable 5 enters from one side of the round box 4, passes through two brush rollers 25 and exits from the other side, ensuring that dust, rainwater, snow or mud on the surface of the cable are effectively removed, and preventing dirt accumulation from affecting the conductivity of the charging interface or the user's grip experience.

[0041] Motor 8 drives turntable 21 to rotate, so that the charging cable 5 is evenly wound, avoiding the mess, knots or excessive bending caused by traditional manual winding, and improving the service life of the cable.

[0042] The way the round box 4 and the bracket 3 are fixed together allows the entire cable reeling mechanism to be tightly integrated with the charging pile body 6, reducing exposed mechanical parts, improving the overall aesthetics, and reducing the risk of damage to the cable reeling device from the external environment.

[0043] The lower end of the charging pile body 6 is fixed with a base 1, and the upper end of the base 1 has four positioning holes arranged in a rectangular row.

[0044] The four positioning holes are arranged in a rectangular pattern and can be firmly connected to the ground with anchor bolts or expansion bolts to prevent the charging pile from tilting or shifting in strong winds, accidental collisions by vehicles, or human shaking.

[0045] The rectangular array's hole design conforms to common installation specifications, making it easy for construction workers to quickly position and fix the object, reducing installation time, and adapting to the fixing needs of different ground surfaces.

[0046] The round box 4 has a cavity 24, and a bearing 20 is fixed inside the cavity 24. The bearing 20 is rotatably connected to the turntable 21. The front end of the bracket 3 has a groove 7, and the inner wall of the groove 7 is rotatably connected to the rotating shaft 9. One end of the rotating shaft 9 is fixed to the drive end of the motor 8 through a coupling, and the other end of the rotating shaft 9 is fixed to the center of the turntable 21.

[0047] Bearing 20 supports the rotation of turntable 21, significantly reducing mechanical wear and ensuring smooth cable winding even after long-term use. Motor 8 directly drives turntable 21 via shaft 9, resulting in a short transmission path, low energy loss, rapid response, and precise control over cable winding and unwinding speeds, preventing the cable from becoming too loose or too tight. The combination of cavity 24 and bearing 20 forms a closed structure, effectively preventing external dust, sand, or rainwater from entering the turntable 21, improving the durability of mechanical components, and making it particularly suitable for use in dusty, humid, or cold environments.

[0048] After the charging cable 5 is inserted into the round box 4, it passes under the lower brush roller 25, between the two brush rollers 25 and above the upper brush roller 25 in sequence, so that it is distributed in an S-shape inside the round box 4, and the charging cable 5 is attached to the outside of the upper and lower brush rollers 25.

[0049] By optimizing the routing path of the charging cable 5 within the circular box 4, it sequentially wraps around the lower side of the brush roller 25, between the two brush rollers 25, and above the upper side of the brush roller 25, forming an S-shaped winding layout. This design significantly increases the contact area between the charging cable 5 and the brush rollers 25, ensuring that the brush can thoroughly clean dust, mud, or other deposits from the surface of the charging cable 5. Simultaneously, the charging cable 5 closely adheres to the outer circumference of the upper and lower brush rollers 25, receiving continuous scraping and cleaning action during movement, avoiding cleaning blind spots that may exist with traditional straight-line routing methods. Furthermore, the S-shaped distribution extends the cleaning path within a limited space, improving the cleaning efficiency of a single cable retraction and unwinding operation.

[0050] Motor 2 17 is fixed at the top and bottom of the other end of the turntable 21. The driving end of motor 2 17 moves through the turntable 21 and is connected to the corresponding brush roller 25.

[0051] When cleaning the charging cable 5 on the new energy vehicle charging station is required, the motor 217 is started when the charging cable 5 is being retracted, causing the brush roller 25 to rotate. The brush roller 25 can clean the dust and impurities on the surface of the retracted charging cable 5. At the same time, the cleaned-off dust and impurities enter the collection tank 14 through the through groove 3 23 and the through groove 1 15 for collection. This achieves the effect of cleaning the dust and impurities on the charging cable 5 as needed, and collecting the cleaned-off dust and impurities simultaneously.

[0052] The turntable 21 serves as the mounting base for the brush roller 25, with motors 17 fixed at its upper and lower ends respectively. The output shaft of each motor 17 passes through the turntable 21 and is directly connected to the corresponding brush roller 25. The integrated layout of the motors 17 and the turntable 21 not only saves space but also facilitates overall disassembly and maintenance—simply disconnecting the turntable 21 allows the brush roller 25 and drive components to be removed together, simplifying the replacement or repair process of the cleaning components.

[0053] The front and rear ends of the round box 4 are respectively provided with through slots 2 19, which are connected to the inner cavity of the round box 4. The charging cable 5 passes through the round box 4 through the two through slots 2 19.

[0054] The through slots 19 at both ends of the round box 4 serve as channels for the charging cable 5 to enter and exit the round box 4. The design of the through slots 19 and the inner cavity of the round box 4 ensures that the charging cable 5 is always within the cleaning range of the brush roller 25 during the winding and unwinding process, while the smooth inner wall of the slot prevents wear on the surface of the charging cable 5.

[0055] A threaded groove 22 is provided on the side of the round box 4 away from the turntable 21. The threaded groove 22 is connected to the inner cavity of the round box 4, and a threaded cap 18 is threadedly connected to the inside of the threaded groove 22.

[0056] The threaded groove 22 on the side wall of the circular box 4 and the threaded cover 18 form a detachable sealing structure. By screwing on the threaded cover 18, one side of the circular box 4 can be quickly opened, facilitating manual cleaning of accumulated dirt or inspection of the wear condition of the brush roller 25. The threaded connection ensures a tight seal while avoiding the cumbersome operation of traditional bolt fixing, making it suitable for scenarios requiring frequent maintenance. When the threaded cover 18 is closed, its inner surface is flush with the inner wall of the circular box 4, preventing interference with the operation of the brush roller 25 or the routing of the charging cable 5, ensuring the continuity of the cleaning process.

[0057] The bottom of the round box 4 is provided with a through groove 23, the bottom inner wall of the support 3 is provided with a groove 13, the front and back of the bottom inner wall of the support 3 are fixed with springs 10, the top of the springs 10 is fixed with an arc plate 12, the arc plate 12 is in contact with the bottom of the round box 4, the upper end of the arc plate 12 is provided with a through groove 15, the lower end of the arc plate 12 is fixed with a collection box 2, the upper end of the collection box 2 is provided with a collection groove 14, the collection box 2 is movable through the groove 13, and the through groove 23, the through groove 15, and the collection groove 14 are connected.

[0058] The through-slot 23 at the bottom of the circular box 4 and the through-slot 15 on the arc-shaped plate 12 inside the bracket 3 together form a waste discharge channel. During the cleaning process, impurities that fall off fall through the through-slot 23 under the action of gravity, and after being guided by the through-slot 15, they enter the collection slot 14 of the collection box 2. The arc-shaped plate 12 is elastically supported at the bottom of the bracket 3 by the spring 10, which can not only buffer the impact of the vibration of the circular box 4 on the collection box 2, but also adaptively adjust its position when the charging cable 5 moves, ensuring that the discharge channel is always aligned.

[0059] The width of groove 2 13 is greater than the width of collection box 2, and the vertical centers of through groove 3 23, through groove 1 15 and groove 2 13 are aligned.

[0060] The vertical center alignment of through groove 3 23, through groove 1 15, and groove 2 13 further optimizes the path of waste falling and prevents impurities from accumulating in the gaps. This precise alignment design, combined with the elastic support of the arc plate 12, ensures the long-term reliability of the waste collection system.

[0061] The bottom end of the arc plate 12 is fixed with screws 11 at the front and rear ends respectively. The bottom end of the bracket 3 is provided with through holes at the front and rear ends respectively. The bottom end of the screw 11 passes through the through holes and the bottom end of the screw 11 is connected with a nut 16 and threaded connection.

[0062] The screw 11 at the bottom of the arc-shaped plate 12 passes through the through hole of the bracket 3 and is locked in place by the nut 16, forming a height-adjustable mechanism. Tightening the nut 16 can change the vertical position of the arc-shaped plate 12 and the collection box 2. The threaded engagement between the screw 11 and the nut 16 serves both tightening and adjustment functions, ensuring the stability of the arc-shaped plate 12 while allowing for fine-tuning without additional tools, thus improving the system's adaptability and ease of maintenance.

[0063] In this embodiment, when it is necessary to reel in the charging cable 5 on the new energy vehicle charging pile, motor 8 is started, causing the rotating shaft 9 and turntable 21 to rotate as needed. Simultaneously, the upper and lower brush rollers 25 rotate to reel in the charging cable 5, fixing one end of the cable 5 to the charging pile. Since the charging head is in a movable state, it can be retracted during the rotation of the turntable 21, preventing any pulling force on the charging cable 5 at the charging pile end. Furthermore, an electric slip ring can be installed on the drive end of motor 8 to facilitate power supply to motor 17 via an external power source, preventing the external wiring of motor 17 from tangling during its rotation. This achieves the effect of facilitating the reeling in of the charging cable 5 while allowing for the release of an appropriate cable length as needed, preventing the charging cable 5 from becoming too long and dragging on the ground, causing damage.

[0064] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
