Slow charging is suitable for use when vehicles are parked for extended periods at home or in the office; the charging process is gentle but takes longer. Fast charging, on the other hand, can replenish a large amount of electricity in a short time and is commonly found in places requiring rapid charging, such as highway service areas. Cable management of charging stations is a key aspect affecting user experience. Currently, cables are mostly suspended using independent cable management devices (such as spring coiling mechanisms).

[0008] Optionally, the fixed pulley assembly further includes a second fixed pulley body, which is rotatably mounted on the fixed pulley seat and arranged horizontally at intervals from the first fixed pulley body. The flexible traction component passes downwards around the lower side of the movable pulley body and upwards around the upper side of the first and second fixed pulley bodies, starting from the first end of the flexible traction component. The rotation axis of the first fixed pulley body is parallel to the rotation axis of the second fixed pulley body.

[0009] Optionally, the column body is provided with a first guide groove extending in the vertical direction. The first guide groove is adapted to the movable pulley assembly.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0031] As described in the background section, charging stations are specialized devices that provide electrical replenishment for electric vehicles, mainly divided into two types: slow charging and fast charging. Slow charging is suitable for use when vehicles are parked for extended periods at home or in the office; the charging process is gentle but takes a long time. Fast charging, on the other hand, can replenish a large amount of electricity in a short time and is commonly found in places requiring rapid charging, such as highway service areas. Cable management of charging stations is a key aspect affecting user experience. Currently, cables are mostly suspended by independent cable management devices (such as spring coiling mechanisms). However, existing cable management devices suffer from uneven resistance and integration difficulties, resulting in a poor user experience.

[0032] See Figures 1 to 6As shown, to solve the above problems, according to one aspect of this application, an embodiment of this application provides a cable suspension device. The cable suspension device includes: a column body 10, a cable suspension part 20, and a counterweight part 30. The cable suspension part 20 includes a movable pulley assembly 21, a fixed pulley assembly 22, and a flexible traction assembly 23. The fixed pulley assembly 22 is installed on the top of the column body 10. The movable pulley assembly 21 is movably installed on the column body 10 and located below the fixed pulley assembly 22. The first end of the flexible traction assembly 23 is fixedly connected to the top of the column body 10. At the first end, the flexible traction component 23 passes sequentially around the movable pulley component 21 and the fixed pulley component 22, and the second end of the flexible traction component 23 is connected to the cable; the counterweight 30 is installed on the column body 10 and can move up and down, and is connected to the movable pulley component 21. The gravity of the counterweight 30 is transmitted to the flexible traction component 23 through the movable pulley component 21. When the cable is not subjected to external force, the flexible traction component 23 can pull the cable to the top of the column body 10 through the gravity of the counterweight 30. The counterweight 30 includes multiple counterweights 31, which are arranged sequentially, and two adjacent counterweights 31 can be detachably connected. The cable suspension device provided in this embodiment features a movable pulley assembly 21 and a fixed pulley assembly 22 on the column body 10. A flexible traction component 23, with its first end fixed to the column body 10 and its second end connected to the cable, is configured to sequentially pass through the movable pulley assembly 21 and the fixed pulley assembly 22. This allows the movable pulley assembly 21, the fixed pulley assembly 22, and the flexible traction component 23 to form a labor-saving pulley group on the column body 10. This also allows the second end of the flexible traction component 23 to have a large range of motion, ensuring that the cable connected to the second end of the flexible traction component 23 has sufficient tension. It has a good degree of freedom of movement. At the same time, by connecting the counterweight 30 to the movable pulley assembly 21, the weight of the counterweight 30 can be transmitted to the flexible traction assembly 23 through the movable pulley assembly 21, thereby changing the tension on the flexible traction assembly 23. The cable suspension device can flexibly adjust the number of counterweights 31 according to the weight of different cables. While ensuring that the cable can be automatically pulled to the top of the column body 10 by the flexible traction assembly 23 when it is not subjected to external force, it can also provide the user with appropriate resistance when pulling the cable, thereby effectively improving the user experience.

[0033] See Figures 3 to 6As shown, in some embodiments, the column body 10 in this embodiment has a receiving cavity. The movable pulley assembly 21 and the fixed pulley assembly 22 in this embodiment are both disposed within the receiving cavity. The top of the column body 10 has a cable outlet hole communicating with the receiving cavity. The first end of the flexible traction assembly 23 is fixedly connected to the top of the receiving cavity, and the second end passes through the movable pulley assembly 21 and the fixed pulley assembly 22 before exiting through the cable outlet hole to the external environment. By embedding the movable pulley assembly 21, the fixed pulley assembly 22, and at least part of the flexible traction assembly 23 within the receiving cavity of the column body 10, the space utilization and environmental protection of the cable suspension device are improved.

[0034] In some embodiments, the flexible traction component 23 in this embodiment includes a flexible traction line, and the two ends of the flexible traction line in this embodiment form the first end and the second end of the flexible traction component 23, respectively.

[0035] See Figure 3 , Figure 4 and Figure 6 As shown, in a specific embodiment, the movable pulley assembly 21 includes a movable pulley seat 211 and a movable pulley body 212. The movable pulley seat 211 is slidably mounted on the column body 10 in the vertical direction, and the movable pulley body 212 is rotatably mounted on the movable pulley seat 211. From the first end of the flexible traction component 23, the flexible traction component 23 sequentially winds downwards around the lower side of the movable pulley body 212 and upwards around the upper side of the fixed pulley assembly 22. By slidably mounting the movable pulley seat 211 on the column body 10 in the vertical direction, it is possible to prevent the movable pulley seat 211 from shifting during cable traction, ensuring the stable transmission of the weight of the counterweight 30. Rotatably mounting the movable pulley body 212 on the movable pulley seat 211 effectively reduces the motion resistance of the flexible traction component 23, ensuring reliable automatic cable pulling while providing a comfortable operating feel and effectively improving the user experience. It should be noted that in this embodiment, the movable pulley seat 211 is fixedly connected to the counterweight part 30.

[0036] In some embodiments, a movable pulley groove is provided on the outer wall of the movable pulley body 212 in this embodiment. The movable pulley body 212 cooperates with the flexible traction component 23 through the movable pulley groove. In this embodiment, the lower side of the movable pulley body 212 refers to the lower side of the movable pulley groove. By providing a movable pulley groove on the outer wall of the movable pulley body 212, precise guidance and stable transmission of the flexible traction component 23 can be achieved. The movable pulley groove ensures that the flexible traction component 23 is always in a good frictional contact position, effectively reducing the operating resistance and wear of the flexible traction component 23 and the movable pulley body 212, which is beneficial to improving the reliability and service life of the cable suspension device.

[0037] See Figure 3 and Figure 4 As shown, in a specific embodiment, the fixed pulley assembly 22 includes a fixed pulley seat 221 and a first fixed pulley body 222. The fixed pulley seat 221 is fixedly installed on the top of the column body 10, and the first fixed pulley body 222 is rotatably installed on the fixed pulley seat 221. The flexible traction component 23 is driven by the first end of the flexible traction component 23. The flexible traction component 23 passes downwards around the lower side of the movable pulley body 212 and upwards around the upper side of the first fixed pulley body 222. The rotation axis of the movable pulley body 212 is parallel to the rotation axis of the first fixed pulley body 222. By fixing the fixed pulley seat 221 to the top of the column body 10, the rigid support of the overall structure of the fixed pulley assembly 22 can be ensured. By rotatably mounting the first fixed pulley body 222 to the fixed pulley seat 221, the motion friction resistance of the flexible traction assembly 23 can be effectively reduced. At the same time, by setting the rotation axis of the movable pulley body 212 to be parallel to the rotation axis of the first fixed pulley body 222, the flexible traction assembly 23 can maintain a good wrap angle when passing around the lower side of the movable pulley body 212 and the upper side of the first fixed pulley body 222, reducing the risk of twisting and wear of the flexible traction assembly 23.

[0038] In some embodiments, a first fixed pulley groove is provided on the outer side wall of the first fixed pulley body 222 in this embodiment. The first fixed pulley body 222 cooperates with the flexible traction component 23 through the first fixed pulley groove. In this embodiment, the upper side of the first fixed pulley body 222 refers to the upper side of the first fixed pulley groove. By providing the first fixed pulley groove on the outer side wall of the first fixed pulley body 222, precise guidance and stable transmission of the flexible traction component 23 can be achieved. The first fixed pulley groove ensures that the flexible traction component 23 is always in a good frictional contact position, effectively reducing the running resistance and wear of the flexible traction component 23 and the first fixed pulley body 222, which is beneficial to improving the reliability and service life of the cable suspension device.

[0039] See Figure 3 and Figure 4As shown, in a specific embodiment, the fixed pulley assembly 22 further includes a second fixed pulley body 223. The second fixed pulley body 223 is rotatably mounted on the fixed pulley seat 221 and is arranged horizontally at a distance from the first fixed pulley body 222. From the first end of the flexible traction component 23, the flexible traction component 23 sequentially winds downward around the lower side of the movable pulley body 212 and upward around the upper side of the first fixed pulley body 222 and the second fixed pulley body 223, wherein the rotation axis of the first fixed pulley body 222 is parallel to the rotation axis of the second fixed pulley body 223. By rotatably mounting the second fixed pulley body 223 onto the fixed pulley seat 221 and arranging the second fixed pulley body 223 and the first fixed pulley body 222 horizontally spaced apart, the flexible traction component 23 can maintain a good contact state with the first fixed pulley body 222 and the second fixed pulley body 223, reducing the frictional loss of the flexible traction component 23. Furthermore, the second fixed pulley body 223 can form a relay-type guide with the first fixed pulley body 222, ensuring the accuracy of the movement trajectory of the flexible traction component 23.

[0040] It is understood that in this embodiment, the flexible traction component 23 moves upward around the upper side of the first fixed pulley body 222 and the upper side of the second fixed pulley body 223, which means that after the flexible traction component 23 moves upward around the upper side of the first fixed pulley body 222, it moves horizontally around the upper side of the second fixed pulley body 223.

[0041] In some embodiments, a second fixed pulley groove is provided on the outer side wall of the second fixed pulley body 223 in this embodiment. The second fixed pulley body 223 cooperates with the flexible traction component 23 through the second fixed pulley groove. In this embodiment, the upper side of the second fixed pulley body 223 refers to the upper side of the second fixed pulley groove. By providing a second fixed pulley groove on the outer side wall of the second fixed pulley body 223, precise guidance and stable transmission of the flexible traction component 23 can be achieved. The second fixed pulley groove ensures that the flexible traction component 23 is always in a good frictional contact position, effectively reducing the operating resistance and wear of the flexible traction component 23 and the second fixed pulley body 223, which is beneficial to improving the reliability and service life of the cable suspension device.

[0042] See Figure 6As shown, in a specific embodiment, the column body 10 in this embodiment is provided with a first guide groove 11 extending in the vertical direction. The first guide groove 11 is adapted to the movable pulley assembly 21. The movable pulley assembly 21 can be slidably installed on the column body 10 in the vertical direction through sliding cooperation with the first guide groove 11. By providing a first guide groove 11 extending vertically on the column body 10, the cable suspension device can stably guide the movement of the movable pulley assembly 21 through the sliding engagement of the first guide groove 11 with the movable pulley assembly 21. Specifically, in this embodiment, the first guide groove 11 can provide rigid guiding constraints for the movable pulley assembly 21, ensuring that it always moves along a predetermined trajectory and avoiding deviation or jamming of the movable pulley assembly 21 during operation. Furthermore, the sliding engagement of the movable pulley assembly 21 with the first guide groove 11 can also enable the gravity of the counterweight 30 to be accurately transmitted in the vertical direction, so that the force applied by the counterweight 30 to the flexible traction assembly 23 through the movable pulley assembly 21 has good directional consistency.

[0043] In some embodiments, the first guide groove 11 in this embodiment is disposed within the receiving cavity. By embedding the first guide groove 11 within the receiving cavity, concealed and precise guidance of the movement trajectory of the movable pulley assembly 21 can be achieved, while the first guide groove 11 can be protected from external environmental corrosion.

[0044] See Figure 6 As shown, in some embodiments, the column body 10 in this embodiment is provided with a second guide groove 12 extending in the vertical direction. The second guide groove 12 is adapted to the counterweight 30, and the counterweight 30 can be slidably installed on the column body 10 in the vertical direction through the sliding engagement with the second guide groove 12. By providing the second guide groove 12 extending in the vertical direction on the column body 10, the cable suspension device can stably guide the movement of the counterweight 30 through the sliding engagement between the second guide groove 12 and the counterweight 30. Specifically, in this embodiment, the second guide groove 12 can provide rigid guiding constraints for the counterweight 30, ensuring that it always moves along a predetermined trajectory and avoiding the offset or jamming of the counterweight 30 during operation. Furthermore, the sliding engagement between the counterweight 30 and the second guide groove 12 can also enable the gravity of the counterweight 30 to be accurately transmitted in the vertical direction, so that the force applied by the counterweight 30 to the flexible traction component 23 through the movable pulley assembly 21 has good directional consistency.

[0045] In some embodiments, the second guide groove 12 in this embodiment is disposed within the receiving cavity. By embedding the second guide groove 12 within the receiving cavity, concealed and precise guidance of the movement trajectory of the counterweight 30 can be achieved, while also protecting the second guide groove 12 from external environmental corrosion.

[0046] See Figure 3 and Figure 4 As shown, in a specific embodiment, one of the two adjacent counterweights 31 is provided with a first connecting structure, and the other of the two adjacent counterweights 31 is provided with a second connecting structure. The two adjacent counterweights 31 are detachably connected through the cooperation of the first connecting structure and the second connecting structure. By providing a first connecting structure on one of the two adjacent counterweights 31 and a second connecting structure on the other, the two adjacent counterweights 31 can be detachably connected through the cooperation of the first connecting structure and the second connecting structure. This allows the counterweights 31 to be flexibly combined according to actual needs, facilitating the cable suspension device to control the traction force of the flexible traction component 23 on the cable.

[0047] See Figure 3 and Figure 4 As shown, in a specific embodiment, the first connecting structure includes a threaded hole, and the second connecting structure includes a stud. The stud is adapted to the threaded hole, and two adjacent counterweights 31 are detachably connected through the engagement of the threaded hole and the stud. By setting the first connecting structure as a threaded hole and the second connecting structure as a stud adapted to the threaded hole, the two adjacent counterweights 31 are detachably connected through the engagement of the threaded hole and the stud. The threaded connection provides reliable mechanical fastening force, ensuring that the counterweights 31 remain stably connected under vibration conditions. Furthermore, the addition, removal, or replacement of the counterweights 31 can be completed simply by tightening, effectively improving the ease of disassembly and maintenance of the cable suspension device.

[0048] In other embodiments, the first connecting structure in this embodiment includes a first hook, and the second connecting structure includes a second hook. The second hook is adapted to the first hook, and two adjacent counterweights 31 are detachably connected through the cooperation of the first hook and the second hook. By setting the first connecting structure as the first hook and the second connecting structure as the second hook adapted to the first hook, the two adjacent counterweights 31 are detachably connected through the cooperation of the first hook and the second hook. The hook connection facilitates the addition, removal, or replacement of the counterweights 31, effectively improving the ease of disassembly, assembly, and maintenance of the cable suspension device.

[0049] See Figures 1 to 4As shown, in a specific embodiment, the cable suspension part 20 further includes a cable connection component 24. The cable connection component 24 is disposed at the second end of the flexible traction component 23, and the second end of the flexible traction component 23 is connected to the cable via the cable connection component 24. By providing the cable connection component 24 at the second end of the flexible traction component 23, the second end of the flexible traction component 23 can be connected to the cable via the cable connection component 24. The provision of the cable connection component 24 can ensure a firm and reliable connection between the flexible traction component 23 and the cable. It should be noted that the cable connection component 24 in this embodiment refers to any device or component capable of realizing a mechanical connection between the flexible traction component 23 and the cable, such as a quick-connect connector, threaded fastener, spring clip, magnetic connector, cable clamp, etc. It is understood that the connection method between the flexible traction component 23 and the cable in this embodiment includes, but is not limited to, mechanical interlocking, friction fixing, or electromagnetic adsorption connection methods. The specific implementation can be adjusted according to the needs of the actual application scenario, as long as reliable force transmission between the flexible traction component 23 and the cable can be satisfied.

[0050] See Figure 1 and Figure 2 As shown, in a specific embodiment, the cable suspension device includes multiple cable suspension parts 20 and multiple counterweight parts 30. The multiple cable suspension parts 20 are arranged at intervals along the circumference of the column body 10, and the multiple counterweight parts 30 correspond one-to-one with the multiple cable suspension parts 20. By arranging the multiple cable suspension parts 20 at intervals along the circumference of the column body 10, and simultaneously making the multiple counterweight parts 30 correspond one-to-one with the multiple cable suspension parts 20, the risk of tilting of the column body 10 caused by unilateral load can be reduced to a certain extent. Furthermore, the arrangement of multiple sets of cable suspension parts 20 and counterweight parts 30 enables the cable suspension parts 20 to support the synchronous independent operation of multiple cables, that is, to allow each cable to extend and retract freely without interference, effectively improving the ease of use of the cable suspension device in high-density cable scenarios.

[0051] According to another aspect of this application, a charging pile is provided, the charging pile including a cable suspension device, the cable suspension device being the aforementioned cable suspension device.

[0052] In some embodiments, the charging pile in this embodiment further includes a charging pile body, which is disposed on the column body 10. By integrating the charging pile body into the column body 10, a compact layout of the charging pile can be achieved, optimizing the space utilization of the charging pile while ensuring good overall structural stability.

[0053] In some embodiments, the charging pile in this embodiment further includes a charging gun and a cable, and the charging gun and the charging pile body are electrically connected by the cable.

[0054] In summary, implementing the cable suspension device and charging pile provided in this embodiment has at least the following beneficial technical effects: The cable suspension device provided in this embodiment, by setting a movable pulley assembly 21 and a fixed pulley assembly 22 on the column body 10, and simultaneously fixing the first end to the column body 10 and the flexible traction component 23 connected to the cable at the second end, is configured to sequentially pass through the movable pulley assembly 21 and the fixed pulley assembly 22, so that the movable pulley assembly 21, the fixed pulley assembly 22, and the flexible traction component 23 can form a labor-saving pulley group on the column body 10, allowing the second end of the flexible traction component 23 to have a large range of motion, ensuring a smooth connection with the cable. The cable connected to the second end of the flexible traction component 23 has good freedom of movement. At the same time, by connecting the counterweight 30 to the movable pulley assembly 21, the weight of the counterweight 30 can be transmitted to the flexible traction component 23 through the movable pulley assembly 21, thereby changing the tension on the flexible traction component 23. The cable suspension device can flexibly adjust the number of counterweights 31 according to the weight of different cables. While ensuring that the cable can be automatically pulled to the top of the column body 10 by the flexible traction component 23 when it is not subjected to external force, the user can experience appropriate resistance when pulling the cable, thereby effectively improving the user experience.

[0055] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
