[0002] With the rapid development and popularization of new energy vehicles, the construction of charging infrastructure is also constantly improving, especially the number of public charging stations. As the core equipment for charging new energy vehicles, the design and performance of charging piles directly affect the user experience. Traditional charging pile cables are usually made of rubber materials. These cables often experience increased wear due to dragging on the ground during use, especially in some public charging stations where wear is more pronounced due to frequent use. Prolonged friction and pulling can cause surface aging, cracks, and even breakage of the cables, affecting their service life and also making them visually unsightly, impacting the overall image of the charging station.

[0003] Furthermore, with the gradual promotion of ultra-fast charging technology, many charging stations have adopted thicker and heavier charging cables to meet the demands of higher power charging. Due to their larger diameter and weight, these cables are often inconvenient for users to operate, especially during the insertion and removal of the charging gun, which requires considerable force. This not only causes inconvenience for users but also seriously affects the charging efficiency and comfort of operators. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and descriptions of this utility model are used to explain the present utility model, but are not intended to limit the present utility model.

[0028] It should be emphasized that the term "including / comprises" as used herein refers to the presence of a feature, element, step, or component, but does not exclude the presence or addition of one or more other features, elements, steps, or components.

[0029] It should also be noted that, unless otherwise specified, the term "connection" in this article can refer not only to a direct connection, but also to an indirect connection involving an intermediary.

[0030] In the following description, embodiments of the present invention will be illustrated with reference to the accompanying drawings. In the drawings, the same reference numerals represent the same or similar parts, or the same or similar steps.

[0031] This invention provides a charging station cable management device and a charging station, aiming to improve some problems in existing charging station cable management, such as cable wear and tear from dragging on the ground, inconvenience of use, and excessive weight. The charging station cable management device of this invention, through innovative structural design and reasonable component configuration, effectively improves cable management, ensuring a longer service life and a better user experience.

[0032] Firstly, this utility model provides a charging station cable management device, such as... Figures 1-3 As shown, the device includes: a mounting base 1, a central shaft 2 and a coil spring 3 disposed in the mounting base 1, a cantilever 5 and a gun wire connector 6, a damper 4, etc.

[0033] In this embodiment, one end of the coil spring 3 is connected to the central shaft 2, and the other end is connected to the coil spring 3. The central shaft 2 is rotatably connected to the mounting base 1. One of the central shaft 2 and the mounting base 1 serves as a fixing component to secure the charging cable management device to the top or side of the charging pile, while the other serves as a rotating component. In the first embodiment, the design of using the central shaft 2 as a rotating component and the mounting base 1 as a fixing component is relatively simple. The operation of the rotating component can be achieved through a rotating shaft, avoiding complex rotating mechanisms or parts. The fixed mounting base 1 provides higher stability, reducing wear and malfunctions caused by too many rotating parts. Simultaneously, when the central shaft 2 serves as a rotating component, it may be easier to achieve smooth charging cable retrieval. If the mounting base 1 remains fixed, rotating components (such as the central shaft 2) will not experience frequent friction during charging cable retrieval, extending their service life. In the second embodiment, using the mounting base 1 as a rotating component allows for greater flexibility in use, especially when the charging pile needs to be adjusted at different angles or positions; the rotation of the mounting base 1 provides greater freedom. The rotating mounting base 1 can better accommodate the extension range of the cable, avoiding angle limitations or cable tangling that may occur when the central shaft 2 is fixed. In actual use cases, the most suitable design solution can be selected by comprehensively considering factors such as the specific scenario and cost.

[0034] Furthermore, one end of the cantilever 5 is connected to the rotating component, and the other end is connected to the cable connector 6. The cantilever 5 itself serves to support and guide the cable, ensuring that the cable does not drag on the ground and avoids wear during use. The cable connector 6 is used to suspend the cable; through reasonable layout and design, it avoids contact between the cable and the ground, reducing the risk of wear. In addition, the cooperation between the cantilever 5 and the rotating component can also reduce the burden on the user through multiple mechanisms such as leverage, spring assistance, center of gravity balance, and friction control. During use, the user can avoid bearing the full weight of the cable through reasonable torque distribution, assistance mechanisms, and automatic balancing systems, thus achieving a more relaxed and smooth operating experience.

[0035] Furthermore, the output structure of the damper 4 is connected to the rotating component. The coil spring 3 provides driving force during the return of the wire from the pulled-out position to the initial position, and the damper 4 provides viscous resistance during at least part of the return process. The damper 4 regulates the wire retrieval speed, controlling it to prevent damage to the wire or equipment caused by excessively rapid retrieval. By providing appropriate resistance, the damper 4 ensures smooth wire return and improves the overall stability of the device.

[0036] In this embodiment of the invention, the working process of the charging cable management device is as follows: When the user unplugs the charging gun to charge the vehicle, the charging cable is suspended at the bottom of the cantilever 5 through the charging cable connector 6. The cantilever 5 can rotate at a certain angle (with the axis of the central shaft 2 as the axis), keeping the charging cable suspended in the air to avoid dragging on the ground and wear. After charging is completed, the user plugs the charging gun back into the charging pile. Due to the reset action of the coil spring 3, the charging cable and the cantilever 5 are automatically retracted. During the retraction process, the viscous resistance provided by the damper 4 ensures that the charging cable resets at an appropriate speed, preventing collisions or loosening of the charging cable, cantilever 5, and other structures due to excessively fast reset. At the same time, the design of the cantilever 5 and the rotating component allows it to bear part of the weight of the charging cable, achieving a power assist effect and further improving ease of use.

[0037] In the above embodiments, the charging cable management device of this utility model, through its suspension design, avoids the charging cable from dragging on the ground, thereby reducing wear and damage to the appearance; the design of the cantilever 5 and the rotating component can bear part of the weight of the charging cable, thereby enabling a more relaxed and smooth charging operation; the charging cable retrieval process is stable, avoiding mechanical collisions or structural loosening and damage caused by excessive weight of the charging cable or too fast retrieval; the damper 4 can provide appropriate resistance, avoiding safety hazards caused by excessively fast charging cable retrieval.

[0038] In some embodiments, such as Figures 2-5 As shown, the mounting base 1 has several connection holes 11 for fixing to the top or side of the charging pile by threaded fasteners; this design makes the installation process simple and ensures a stable connection between the mounting base 1 and the charging pile.

[0039] In some embodiments, such as Figure 4 As shown, the damper 4 is disposed within the mounting base 1, its output structure is fixedly connected to the central shaft 2, and its housing structure is fixedly connected to the mounting base 1. The damper 4 directly affects the movement of the central shaft 2, and can be used to reduce vibration or impact in the mechanical system, ensuring smooth movement. Through its connection with the central shaft 2, the damper 4 can limit the shaft's speed, reduce vibration, or adjust rotational inertia. The fixed connection of the damper 4's housing structure to the mounting base 1 further enhances the stability and fixation of the damper 4 during operation, ensuring that the damper 4 can effectively perform its vibration reduction and speed regulation functions. The damper 4 can effectively extend the service life of the gun wire management device.

[0040] In some embodiments, the damper 4 is a rotary damper, including any one of a viscous damper, a magnetorheological damper, a gear-driven damper, and a composite avoidance structure damper. A rotary damper achieves a damping effect through rotational motion to slow the movement of rotating components, thereby controlling vibrations, shocks, or unnecessary accelerations to ensure smooth system operation. A viscous damper achieves a damping effect through the viscosity of a fluid, for example, using a liquid (such as oil) to generate resistance. As rotation proceeds, the liquid flows inside the damper 4, generating viscous resistance, thereby slowing the movement of the rotating components. A magnetorheological damper uses a magnetorheological fluid (a liquid whose viscosity can be changed) as a medium. The viscosity of the magnetorheological fluid is adjusted using an external magnetic field, thereby providing different degrees of damping under different conditions, exhibiting good responsiveness and adjustability. A gear-driven damper achieves a damping effect through gears and a gear transmission system. The gear transmission method reduces rotational speed by increasing friction, thus achieving a damping effect. Composite avoidance structure dampers can achieve damping effects through a variety of mechanisms and structures, including mechanical, spring, friction, and avoidance design. This structure optimizes the damping effect by combining different elements and can provide flexible performance adjustment under more complex conditions.

[0041] As at least one possible approach, the damper 4 and the coil spring 3 can construct a "coil spring-damping" dual-mode drive system, forming a dynamic balance between the viscous resistance of the damper 4 and the elastic potential energy of the coil spring 3; the damper 4 can be adjusted to achieve a nonlinear velocity decay curve, for example, to keep the cantilever 5 at a constant speed in the 0°-90° unfolding stage and gradually decelerate in the 90°-180° stage; optionally, the damper 4 can also introduce a velocity-sensitive damping adjustment mechanism (such as shear thickening fluid technology) to automatically enhance the damping coefficient when a sudden load is applied.

[0042] Furthermore, the "coil spring-damping" dual-mode drive system constructed by damper 4 and coil spring 3 can achieve a three-stage return state during the reset process of the gun line and cantilever 5, such as: the initial stage for easy start with low damping (0°-30°); the working stage for smooth movement with constant damping (30°-150°); and the return stage for gradual damping and buffer braking (150°-180°). The functions of damper 4 include, but are not limited to: slowing down the reset speed and reducing impact; improving stability and preventing accidental movement; reducing noise; and improving the operating feel.

[0043] In the above embodiments, rotary dampers provide different damping effects through different types (viscous, magnetorheological, geared, and composite avoidance structures). Each of these types has its unique working principle and advantages, and the appropriate damper type can be selected according to specific application requirements. For example, magnetorheological dampers are suitable for applications requiring adjustable damping strength, while geared dampers are suitable for systems with high stability requirements.

[0044] In some embodiments, such as Figures 2-5 As shown, the mounting base 1 includes a base 12, a column 13, and a top 14. The base 12 and the top 14 are connected by the column 13 on the side. The column 13 provides support, maintaining a fixed position between the base 12 and the top 14 and providing a stable structural foundation. The two ends of the central shaft 2 are respectively mounted in the base 12 and the top 14 via bearings 15 or bushings. The coil spring 3 and the damper 4 are also mounted in the base 12. The bearings 15 or bushings reduce friction, improve rotational efficiency, and ensure that the central shaft 2 maintains a stable axial position during movement. The structural design in this embodiment provides a robust and stable frame by combining the base 12, column 13, and top 14. The central shaft 2 is fixed in the base 12 and top 14 via bearings 15 or bushings, ensuring its free rotation, and the coil spring 3 and damper 4 regulate the dynamic response of the system. The coil spring 3 provides elastic support, while the damper 4 controls vibration and impact, ensuring smooth operation of the entire system.

[0045] In some embodiments, such as Figure 4 As shown, the bottom chamber 12 of the mounting base 1 also includes a sealing cover 16, which seals the interior of the bottom chamber 12 to prevent external contaminants from entering. The sealing cover 16 has a through hole in the center for the central shaft 2 to pass through. A sealing ring 17 is provided between the sealing cover 16 and the shell of the bottom chamber 12 and / or between the sealing cover 16 and the central shaft 2. Lubricating oil or grease can be provided inside the bottom chamber 12 to reduce wear on the coil spring 3, reduce friction and noise, extend its service life, and improve its working efficiency. The sealing ring 17 prevents external substances such as air, moisture, and dust from entering the bottom chamber 12 and prevents leakage of internal lubricating oil or grease. The sealing ring 17 effectively prevents external environmental contamination of the bottom chamber 12, while also ensuring the flow and stability of lubricating oil or grease inside the bottom chamber 12, avoiding lubricating oil leakage, and ensuring the normal operation of the system.

[0046] In some embodiments, such as Figure 5As shown, the central shaft 2 also includes a slotted bushing 21 fitted thereon. The slot of the slotted bushing 21 is used to connect the end of the coil spring 3. The slotted bushing 21 is fixed to the central shaft 2 by a set screw or by adhesive bonding. The slotted design provides a convenient way to fix the end of the coil spring 3 to the bushing, thereby ensuring that the coil spring 3 can work stably during operation. The connection between the slotted bushing 21 and the end of the coil spring 3 effectively ensures the mechanical linkage between the coil spring 3 and the central shaft 2. In actual use, the end of the coil spring 3 is fixed by the slot, avoiding the risk of the coil spring 3 falling off or loosening during operation. The set screw fastens the slotted bushing 21 to the central shaft 2, ensuring the bushing's firmness and stability, and enabling it to withstand large working loads.

[0047] In the above embodiments, compared to using an integrated stepped shaft structure, this utility model embodiment uses an assembly design of a central shaft 2 plus an external bushing. Its manufacturing process is simpler, as it does not require machining complex stepped shapes on the shaft. The external bushing can be completed through simple machining or assembly, eliminating the need for additional precision machining of the shaft and reducing the complexity of the production process. The external bushing design can be replaced or adjusted as needed, offering high flexibility. If the bushing needs to be replaced or the component size adjusted, only the external bushing needs to be replaced, without remanufacturing the entire shaft. In contrast, stepped shaft designs are typically machined as a single unit, making modifications difficult once completed. Stepped shafts have multiple dimensional changes, and such transitions may cause stress concentration in the stepped sections, affecting the shaft's strength and durability. The external bushing, through proper design, can avoid this problem because it can evenly distribute the load, reducing localized stress concentration. In practical applications, the external bushing can be inspected, maintained, and replaced independently without disassembling the entire central shaft 2. This is highly advantageous for long-term maintenance and repair. In contrast, if a stepped shaft wears out or is damaged, the entire shaft often needs to be replaced, which is costly and time-consuming.

[0048] In some embodiments, such as Figure 2 As shown, the column 13 has several pads 18 on its side facing the cantilever 5. The main function of these pads 18 is to absorb the hard impact between the cantilever 5 and the column 13 caused by inertia when the cantilever 5 returns to its original position. During movement, the cantilever 5 may over-return due to inertia, directly colliding with the column 13. To reduce the impact force, vibration, and wear caused by the impact, the pads 18 are designed to effectively buffer these forces and reduce damage to the column 13 and the cantilever 5. The pads 18 can be made of elastic and shock-absorbing materials (such as rubber, polyurethane, etc.), which can absorb some of the impact energy through deformation when the cantilever 5 returns to its original position, thereby reducing damage to the equipment and vibration of the system; this not only improves the durability of the device but also enhances its stability and service life.

[0049] In some embodiments, the cantilever 5 is a straight or broken-line structure (or L-shaped); such as Figures 2-4 As shown, when the cantilever 5 has a polygonal structure, the two cantilever segments 5 are either fixedly connected or rotatably connected at the inflection point. In the design of the polygonal cantilever 5, the rotatable connection is particularly crucial, allowing for a certain degree of relative movement between the two cantilever segments 5, thereby achieving greater flexibility and a wider range of motion. Furthermore, a torsion spring is provided at the rotatable connection to increase its swing range and improve the flexibility of the cantilever 5. The torsion spring provides elastic restoring force, allowing the two cantilever segments 5 to swing freely within a certain range during relative movement, increasing the system's flexibility and adaptability. Optionally, when the cantilever 5 has a linear structure, the cantilever 5 can be a single continuous structure or two rotatably connected segments.

[0050] In some embodiments, such as Figure 4 As shown, the cantilever 5 includes a cantilever sleeve 51, which is connected to the central shaft 2 via a key. The key connection provides strong torsional resistance, effectively transmitting torque and preventing relative rotation or slippage between the cantilever sleeve 51 and the central shaft 2. This design ensures a tight fit between the cantilever sleeve 51 and the central shaft 2 during use, preventing loosening or detachment due to force. The cantilever sleeve 51 is inserted into the main body of the cantilever 5 and fixed by connectors 53. This connection method ensures a tight fit between the cantilever sleeve 51 and the main body of the cantilever 5, maintaining a stable structure. The insertion design facilitates quick assembly and disassembly while ensuring a strong and stable connection. These connectors 53 may be screws, nuts, retaining pins, or other types of fasteners, used to ensure the stability of the insertion points and prevent loosening or displacement due to external forces or vibrations during use.

[0051] Secondly, such as Figure 1 As shown, this utility model provides a charging pile, which includes the aforementioned gun wire management device.

[0052] In this embodiment, the synergistic effect of the coil spring 3 and the damper 4 forms a closed-loop mechanical adjustment mechanism. When the charging cable is pulled out, the coil spring 3 provides uniform energy storage and release, combined with the dynamic resistance characteristics of the damper 4, ensuring a smooth and effortless operation. During the reset phase, the damper 4 effectively buffers mechanical impact through gradual resistance changes, preventing collision wear caused by rapid cable retraction. The lever structure of the cantilever 5, combined with the phase adjustment function of the damper 4, allows the charging cable to move along an optimized path during pulling out and retraction, significantly reducing frictional contact with the external environment and reducing stress concentration in the mechanical structure. This invention significantly reduces surface wear and internal core fatigue of the charging cable by eliminating dragging friction and impact damage, reducing resource waste caused by frequent replacements. Elderly users, women, and other user groups can easily perform charging cable insertion and removal operations. In cold environments, the charging cable maintains its flexibility without additional force, improving user experience consistency. The compact design of this device supports flexible installation on the top or side, avoiding the encroachment of traditional cable management devices on the charging pile's operating space and maintaining a clean appearance.

[0053] This invention achieves breakthroughs in core indicators such as automatic charging cable reset accuracy, environmental adaptability, and operational comfort through mechanical structural innovation, while also considering manufacturing costs and maintenance economy, providing a reliable technical path for the intelligent upgrading of charging piles. Furthermore, this charging cable management device can also be applied to scenarios such as charging cable management in gas stations.

[0054] In this invention, features described and / or illustrated for one embodiment may be used in the same or similar manner in one or more other embodiments, and / or combined with or in place of features of other embodiments.

[0055] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. For those skilled in the art, various modifications and variations can be made to the embodiments of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
