[0027] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the invention and to fully convey the scope of the invention to those skilled in the art.

[0028] Charging stations are essential supporting facilities for charging new energy vehicles. With the increasing prevalence of charging stations, people's demands for their use are also rising. Existing charging stations consist of a charging gun assembly and a station body assembly. The charging gun assembly generally includes a charging gun and a cable. The charging gun connects to the vehicle's charging port, and the cable establishes the electrical connection between the charging gun and the station body. To ensure charging range, the cable in the charging gun assembly is generally designed to be relatively long. With advancements in fast charging technology, the cables are also becoming thicker. This means that part of the cable will drag on the ground under its own weight. During use, the part of the cable in contact with the ground is easily damaged due to friction, thus affecting the lifespan of the charging station. Cables dragging on the ground can also trip users or soil their clothing, and the cable's weight further inconveniences users.

[0029] refer to Figure 1 To address the aforementioned issues, this application provides a charging pile, specifically comprising a support pile 1, a suspension assembly 2, and a suspension cable 3.

[0030] refer to Figure 2 The support pile 1 is the main body providing power in the charging pile, and its shape can be configured in various ways. For example, the support pile 1 can be a columnar structure, or it can be cubic or even have an irregular shape; details will not be elaborated here. The suspension assembly 2 is connected to the support pile 1. Specifically, the suspension assembly 2 can be located inside or outside the support pile 1. The suspension assembly 2 and the support pile 1 can be fixedly connected by fasteners, welding, or other methods, and it is used to suspend the suspension cable 3.

[0031] refer to Figure 3The suspension cable 3 is a conductive structure that electrically connects the support pile 1 and the charging gun 4 on the charging pile. With the suspension cable 3 connected, the power provided by the support pile 1 can be transmitted to the vehicle via the charging gun 4. The charging pile can have only one suspension cable 3 and two, three, four, or even more charging guns 4 connected to it; the specific number can be set according to actual needs. For example, two suspension cables 3 can be installed on the charging pile, each end of which is connected to a charging gun 4. The two suspension cables 3 can be located on the same side of the support pile 1 or symmetrically on opposite sides of the support pile 1. The suspension assembly 2 is connected to the suspension cable 3 so that the suspension cable 3 is suspended in the air, and the suspension cable 3 also suspends the charging gun 4 in the air. This prevents any part of the suspension cable 3 from dragging on the ground; that is, the entire suspension cable 3 is suspended in the air. Benefiting from the suspension of the suspension cable 3, it will not be damaged due to friction with the ground, which helps to ensure the service life of the suspension cable 3, and thus ensures the overall service life of the charging pile. The suspension cable 3 will also not get dirty due to friction with the ground. Even if users come into contact with the suspension cable 3 while using the charging station, they are unlikely to get their bodies or clothes dirty, which improves the user experience. The suspension cable 3, suspended in the air, also avoids becoming a road obstacle on the ground, preventing it from obstructing passage or causing tripping hazards. The suspension component 2 in the charging station can also support the weight of the suspension cable 3, so users do not need to overcome its weight when retrieving the charging gun 4, thus providing a more convenient user experience.

[0032] Simultaneously, when the user pulls the suspension cable 3, the connection point between the suspension cable 3 and the suspension component 2 can adaptively move to expand the lateral span and range of motion of the suspension cable 3. The suspension component 2 applies a suspension effect to the suspension cable 3 to counteract the influence of the cable's own weight, providing the user with a zero-gravity experience. The suspension component 2 also helps ensure that the unsuspended portion of the suspension cable 3 remains straight under gravity, preventing the cable from overlapping or tangling, thus ensuring the efficiency and effectiveness of the charging pile's management of the suspension cable 3.

[0033] In some embodiments of this application, the suspension component 2 can be disposed outside the support pile 1 or embedded inside the support pile 1. Preferably, at least a portion of the suspension component 2 is located within the support pile 1, i.e., the support pile 1 and the suspension component 2 adopt an integrated design concept. Based on the integrated arrangement of the support pile 1 and the suspension component 2, the support pile 1 and the suspension component 2 can achieve good coordination in spatial layout. This is beneficial for optimizing the space utilization of the charging pile, allowing the charging pile to be designed to be smaller and significantly reducing the cost of the charging pile. Having at least a portion of the suspension component 2 located within the support pile 1 also simplifies the appearance of the charging pile, reduces design difficulty, and allows the suspension component 2 to be protected within the support pile 1, thereby improving the overall reliability and service life of the charging pile.

[0034] refer to Figure 4 In some embodiments of this application, optionally, the suspension assembly 2 includes a traction mechanism 21, which can move relative to the support pile 1 to drive the suspension cable 3 to move relative to the support pile 1. Specifically, the suspension cable 3 has an initial position and a working position relative to the support pile 1. The initial position is the position where the suspension cable 3 is naturally held by the suspension assembly 2 without being subjected to external force from the user. The working position is the position where the suspension cable 3 is located when the charging gun 4 of the charging pile is connected to the vehicle charging port when the user is using the charging pile. There are usually multiple working positions, which can be determined according to the location of the vehicle charging port. During use, the user moves the suspension cable 3 from the initial position to the working position by manually lifting or other means. After use, the suspension assembly 2 can apply external force to the suspension cable 3 through the traction mechanism 21, so that the suspension cable 3 can be reset from the working position to the initial position. In this process, the traction mechanism 21 can facilitate the reset of the suspension cable 3, so that the suspension cable 3 can be reset according to a preset path or preset method, thereby ensuring the reliability and smoothness of the reset of the suspension cable 3.

[0035] refer to Figure 5 In some embodiments of this application, the suspension assembly 2 optionally includes a connector 22, which connects the traction mechanism 21 and the suspension cable 3. The connector 22 can be a flexible structure such as a metal rope, polymer rope, or metal chain, or it can be a rigid rod or other rigid structure. The traction mechanism 21 can drive the suspension cable 3 by moving the connector 22. During this process, the connector 22 facilitates the connection between the traction mechanism 21 and the suspension cable 3, ensuring a reliable connection between them. Based on this improved connection, the traction mechanism 21 can more easily ensure the reliability and smoothness of the suspension cable 3's repositioning.

[0036] refer to Figure 4In some embodiments of this application, optionally, the traction mechanism 21 includes a first traction structure 211, which can drive the connecting member 22 to move. The first traction mechanism 21 can drive the suspension cable 3 to move by driving the connecting member 22 to ensure the reliability and smoothness of the reset of the suspension cable 3.

[0037] refer to Figure 5 In some embodiments of this application, optionally, the traction mechanism 21 includes a second traction structure 212, and the connecting member 22 is movable relative to the second traction structure 212. Specifically, the second traction structure 212 can guide or constrain the movement direction of the connecting member 22 to ensure that the connecting member 22 has a reliable and definite movement path. This helps to ensure that the connecting member 22 and the suspension cable 3 connected to the connecting member 22 move along a preset path, thereby ensuring the reliability and smoothness of the reset of the suspension cable 3.

[0038] In some embodiments of this application, the first traction structure 211 and the second traction structure 212 may be provided individually or simultaneously. This means that the charging pile can have more flexible and diverse configuration schemes based on the configuration of the first traction structure 211 and the second traction structure 212. This is beneficial for broadening the applicable scenarios of the charging pile and also allows the layout of the charging pile to meet user needs as closely as possible.

[0039] refer to Figure 4 In some embodiments of this application, optionally, the first traction structure 211 is rotatable relative to the support pile 1, and the connector 22 is wound around the first traction structure 211. The first traction structure 211 can specifically be a roller structure such as a winding wheel 2111, or a winding shaft or other wound structure. Correspondingly, the connector 22 is a flexible structure, specifically a steel wire rope, chain, or other structure. In idle conditions, the first traction structure 211 does not move; only the connector 22 applies a holding force to the suspended cable 3, allowing the suspended cable 3 to overcome its own weight and remain suspended. During use, the user can move the suspended cable 3 arbitrarily; the connector 22 adapts to the movement of the suspended cable 3, and the first traction structure 211 rotates in response to the movement of the connector 22. After use, the first traction structure 211 rotates to drive the connector 22 to retract and wrap around the first traction structure 211 until the suspended cable 3 can return to its initial position in the idle condition. The rotatable structure of the first traction structure 211 helps ensure reliable movement of the connector 22. When the connector 22 is a flexible structure such as a rope, it is less likely to become knotted, jammed, or interfere with other structures. This helps ensure the synchronization of the movement of the suspension cable 3 and the connector 22 during charging, thereby improving the user's experience with the charging station.

[0040] refer to Figure 5In some embodiments of this application, optionally, the first traction structure 211 is slidable relative to the support pile 1, and the connecting member 22 is connected to the first traction structure 211. In this case, the first traction structure 211 can be a slider, a movable pulley 2115, or other structures, which can be specifically set according to actual needs. The first traction structure 211 is connected to the connecting member 22. In idle scenarios, the first traction structure 211 does not move; it only applies a holding force to the suspended cable 3 through the connecting member 22, so that the suspended cable 3 overcomes its own weight and remains suspended. During use, the user can move the suspended cable 3 arbitrarily, and the connecting member 22 moves to adapt to the movement of the suspended cable 3. The first traction structure 211 moves in accordance with the movement of the connecting member 22. After use, the first traction structure 211 moves to drive the connecting member 22 to move and reset, so that the suspended cable 3 can return to its initial position in the idle scenario.

[0041] When the first traction structure 211 is rotatably mounted on the support pile 1, elastic elements 232 such as coil springs and spring balancers can be used to drive the first traction structure 211 to rotate. When the connecting piece 22 is pulled out, the first traction structure 211 will pull out the spring sheet of the elastic element 232 and wrap it in the opposite direction around its own periphery. This means that when using the charging pile, the spring sheet of the elastic element 232 will repeatedly perform two actions of reverse winding and forward winding during the process of the connecting piece 22 being pulled out and retracted. This can easily lead to fatigue failure of the spring sheet, which in turn leads to premature failure of the elastic element 232 and affects the service life of the charging pile. Sliding the first traction structure 211 onto the support pile 1 can avoid the problem of the spring sheet of the elastic element 232 wrapping in the opposite direction. This helps to ensure the service life of the elastic element 232, and thus ensure the service life of the charging pile.

[0042] refer to Figure 9 In some embodiments of this application, optionally, the first traction structure 211 includes a winding wheel 2111, which is rotatable relative to the support pile 1. Specifically, the winding wheel 2111 may have a rotating shaft, which is inserted into a mounting hole on the support pile 1 to allow the winding wheel 2111 to rotate relative to the support pile 1. Alternatively, the support pile 1 may have a rotating shaft, and the winding wheel 2111 may have a mounting hole. The rotating shaft is inserted into the mounting hole to allow the winding wheel 2111 to rotate relative to the support pile 1. The connecting member 22 may specifically be a flexible structure such as a wire rope or chain. The connecting member 22 is wound around the winding wheel 2111 by a winding method and extends or retracts as the winding wheel 2111 rotates. The first traction structure 211 uses a rotatable winding wheel 2111, which helps to ensure the reliable movement of the connecting member 22. When the connecting member 22 is a flexible structure such as a rope, it is less likely to get knotted, stuck, or interfere with other structures. This helps ensure the synchronization of movement between the suspension cable 3 and the connector 22 during charging, thereby improving the user's experience with the charging station.

[0043] refer to Figure 5 Alternatively, in some embodiments of this application, the first traction structure 211 can also be a first sliding member 2112, which can specifically be a rigid slider, sliding rod, or other structure. The first sliding member 2112 is slidable relative to the support pile 1, and the connecting member 22 is wound around the first sliding member 2112. One end of the connecting member 22 is fixedly connected to the support pile 1, and the other end of the connecting member 22 is connected to the suspension cable 3. In this case, the first sliding member 2112 and the connecting member 22 are actually equivalent to a movable pulley 2115 system. Based on the labor-saving and long-distance characteristics of the movable pulley 2115 system, when the user moves the suspension cable 3, the movement stroke of the connecting member 22 will be much greater than the movement stroke of the first sliding member 2112. When the first traction structure 211 and the connecting member 22 are set inside the support pile 1, this helps to save space inside the support pile 1 and allows the first traction structure 211 and the connecting member 22 to better adapt to the internal space of the support pile 1. At the same time, the force required for the user to move the suspension cable 3 can be significantly reduced based on the aforementioned pulley 2115 system, which can bring convenience to the user and improve the user experience of the charging station.

[0044] Or, refer to Figure 10 In some embodiments of this application, the first traction structure 211 includes a transmission member 2113 and transmission wheels 2114. Two or more transmission wheels 2114 may be provided, and the transmission member 2113 surrounds the periphery of all transmission wheels 2114. The transmission member 2113 may be a transmission chain, in which case the transmission wheels 2114 are specifically sprockets, and the transmission wheels 2114 mesh with the transmission member 2113. The transmission member 2113 may also be a transmission belt, in which case the transmission wheels 2114 are specifically pulleys, and the transmission wheels 2114 are in contact with the transmission member 2113. The transmission wheels 2114 are rotatable relative to the support pile 1 to drive the transmission member 2113 to move relative to the support pile 1. The connecting member 22 is fixedly connected to the transmission member 2113 by welding, fastener connection, or other means, so that the transmission member 2113 can drive the connecting member 22 to move relative to the support pile 1. Based on the belt drive or chain drive structure formed by the transmission component 2113 and the transmission wheel 2114, the first traction structure 211 can achieve smoother movement, which helps to ensure the smoothness and reliability of the suspension cable 3 during resetting. By specifically controlling the size of the transmission wheel 2114, the first traction structure 211 can also meet different transmission ratio requirements. This improves the flexibility of use of the first traction structure 211, enabling it to be applied in traction mechanisms 21 with different transmission ratio requirements.

[0045] By adopting the above-described scheme, the first traction structure 211 can significantly simplify its structure, thereby reducing its structural and material costs. This facilitates the layout of the first traction structure 211, enabling flexible integration and collaborative design between the traction mechanism 21 and the support pile 1, reducing the design difficulty of the charging pile, and improving the overall integration and aesthetics of the charging pile. The specific selection of the first traction structure 211 can be flexibly adjusted according to the size of the charging pile and the coverage requirements of the suspension cable 3, so that the first traction structure 211 can better match the actual structure of the charging pile and the user's needs.

[0046] Or, refer to Figure 4 In some embodiments of this application, the first traction structure 211 includes a first sliding member 2112 and a movable pulley 2115. The first sliding member 2112 is slidable relative to the support pile 1. Specifically, a slide rail can be provided on the support pile 1, and the first sliding member 2112 is slidably connected to the slide rail. The movable pulley 2115 is connected to the first sliding member 2112 through a rotating shaft, rotating pin, or other structures, so that the movable pulley 2115 is rotatable relative to the first sliding member 2112 and the support pile 1. A connecting member 22 is wound around the movable pulley 2115. Specifically, one end of the connecting member 22 is fixedly connected to the support pile 1, and the other end of the connecting member 22 is connected to the suspension cable 3 after passing around the movable pulley 2115. At this time, the movable pulley 2115, the first sliding member 2112, and the connecting member 22 are actually equivalent to a movable pulley 2115 system. Based on the labor-saving and long-distance characteristics of the movable pulley 2115 system, when the user moves the suspended cable 3, the travel distance of the connector 22 is much greater than the sliding distance of the first sliding member 2112 and the movable pulley 2115. This allows the connector 22 to extend its range of motion, covering a larger space. When the first traction structure 211, the movable pulley 2115, and the connector 22 are located inside the support pile 1, this saves space inside the support pile 1, allowing the first traction structure 211 and the connector 22 to better fit the internal space of the support pile 1. At the same time, the force required for the user to move the suspended cable 3 under the same travel distance can also be significantly reduced based on the aforementioned movable pulley 2115 system. This provides convenience for users using the charging pile and improves their user experience. Based on this, the first sliding member 2112 can provide directional assurance for the overall movement of the first traction structure 211, and the movable pulley 2115 can improve the contact between the first traction structure 211 and the connecting member 22, so as to reduce the frictional resistance between the first traction structure 211 and the connecting member 22.

[0047] refer to Figure 5In some embodiments of this application, optionally, the second traction structure 212 is rotatable relative to the support pile 1, and the connecting member 22 is wound around the second traction structure 212. Specifically, the second traction structure 212 can be a fixed pulley 2121 or a shaft-like part, and part of the connecting member 22 is wound around the periphery of the second traction structure 212 so that adjacent parts of the connecting member 22 located on different sides of the second traction structure 212 can have different extension directions. The second traction structure 212 can guide the connecting member 22, giving it a more flexible direction of travel. Based on the arrangement of the second traction structure 212, the connecting member 22 can achieve a more complex extension path while connecting the suspension cable 3 and the traction mechanism 21. This provides more flexible arrangement options for the traction mechanism 21, allowing the arrangement position of the traction mechanism 21 to better adapt to the shape of the support pile 1. In other words, when the connector 22 is adapted to the support pile 1, it can flexibly adjust its bending direction and angle according to the internal structural space arrangement of the support pile 1, so as to achieve efficient matching with the structure of the support pile 1, thereby improving the spatial adaptability and overall integration of the suspension assembly 2. When upgrading an existing charging pile to the charging pile described in this application, the traction mechanism 21 can adapt to the structure of the existing charging pile as much as possible, so as to reduce the change cost when upgrading the existing charging pile to the charging pile described in this application.

[0048] refer to Figure 10 Alternatively, in some embodiments of this application, the second traction structure 212 may be fixedly connected to the support pile 1, and the connecting member 22 may be slidable relative to the second traction structure 212. In this case, the second traction structure 212 may specifically be a guide rail 2122, a guide rod, or other structures. The second traction structure 212 may extend along a straight trajectory, or along a curved or broken line trajectory, depending on actual needs, which will not be elaborated here. This provides more flexible arrangement options for the traction mechanism 21, allowing the arrangement position of the traction mechanism 21 to better match the shape of the support pile 1. Simultaneously, by changing the extension direction of the connecting member 22, the extendable length of the connecting member 22 can also be increased. The extension direction of the second traction structure 212 depends on the sliding direction of the connecting member 22, and the length of the second traction structure 212 depends on the aforementioned stroke of the connecting member 22, which will not be elaborated here. The second traction structure 212 may be an independent structure, or it may be integrated into a single component with the structural beams or other mechanical structures within the support pile 1. The aforementioned connector 22 is slidably connected to the second traction structure 212. Based on the guiding effect of the second traction structure 212 on the connector 22, the connector 22 can more easily maintain its own movement trajectory. This helps to ensure the smooth movement of the connector 22 and the suspension cable 3, thereby improving the smoothness of the user's use of the charging pile. Therefore, this can bring convenience to the user and improve the user experience of the charging pile.

[0049] refer to Figure 6 In some embodiments of this application, optionally, the second traction structure 212 includes a fixed pulley 2121. A connecting member 22 is disposed around the fixed pulley 2121, such that adjacent portions of the connecting member 22 located on different sides of the fixed pulley 2121 can have different extension directions. When the suspension cable 3 moves, the connecting member 22 can move synchronously relative to the fixed pulley 2121. The fixed pulley 2121 rotates with the movement of the connecting member 22 under the action of friction, thereby reducing the frictional resistance experienced by the connecting member 22 during movement. Based on the arrangement of the fixed pulley 2121, the connecting member 22 can achieve a more complex extension path while connecting the suspension cable 3 and the traction mechanism 21. This provides more flexible arrangement options for the traction mechanism 21, allowing its position to better adapt to the shape of the support pile 1. When upgrading an existing charging pile to the charging pile described in this application, the traction mechanism 21 can adapt to the structure of the existing charging pile as much as possible, thereby reducing the change cost when upgrading the existing charging pile to the charging pile described in this application.

[0050] refer to Figure 10 Alternatively, in some embodiments of this application, the second traction structure 212 may optionally include a guide rail 2122, with the connector 22 slidable relative to the guide rail 2122. The extension direction of the guide rail 2122 depends on the sliding direction of the connector 22, and the length of the guide rail 2122 depends on the stroke of the connector 22, which will not be elaborated here. The guide rail 2122 may be an independent structure, or it may be integrated into the same part as the structural beam or other mechanical structure within the support pile 1. The connector 22 is slidably connected to the guide rail 2122. Based on the guiding effect of the guide rail 2122 on the connector 22, the connector 22 can more easily maintain its own movement trajectory. This helps to ensure the smoothness of the movement of the connector 22 and the suspension cable 3, thereby improving the smoothness of the user's use of the charging pile. Therefore, this can bring convenience to the user's use of the charging pile and improve the user's experience of using the charging pile.

[0051] The second traction structure 212, employing the aforementioned fixed pulley 2121 or guide rail 2122, significantly simplifies its structure, thereby reducing structural and material costs. This facilitates the arrangement of the second traction structure 212, enabling flexible integration and collaborative design between the traction mechanism 21 and the support pile 1, reducing the design complexity of the charging pile, and improving its overall integration and aesthetics. The specific selection of the second traction structure 212 can be flexibly adjusted according to the size of the charging pile and the coverage requirements of the suspension cable 3, so that the second traction structure 212 can better match the actual structure of the charging pile and the user's needs.

[0052] refer to Figure 6 , Figure 7 In some embodiments of this application, optionally, the second traction structure 212 includes two fixed pulleys 2121, and a connector 22 is wound around the two fixed pulleys 2121. The portion of the connector 22 located between the two fixed pulleys 2121 extends along the line connecting the axes of the two fixed pulleys 2121, so as to realize two reversals of the connector 22 through the two fixed pulleys 2121. Exemplarily, when the extension direction of the support pile 1 is arranged along the direction of gravity, the two fixed pulleys 2121 can be arranged relatively spaced in the horizontal direction, or the two fixed pulleys 2121 can be arranged relatively spaced in a direction that is arranged at an acute angle to the horizontal direction. The portion of the connector 22 connected to the suspension cable 3 extends along the direction of gravity or in a direction inclined to the direction of gravity, the portion of the connector 22 located between the two fixed pulleys 2121 extends horizontally, and the portion of the connector 22 away from the suspension cable 3 can extend along the direction of gravity or in a direction inclined to the direction of gravity.

[0053] Alternatively, the second traction structure 212 includes at least three fixed pulleys 2121, with at least some of the fixed pulleys 2121 arranged along the same straight line. Exemplarily, when three fixed pulleys 2121 are provided, the three fixed pulleys 2121 can be arranged along the same straight line, or two fixed pulleys 2121 can be arranged along the same straight line, and the third fixed pulley 2121 can be located at a position other than that straight line direction. Four, five, six, or even more fixed pulleys 2121 can be provided. The connecting member 22 is wound around all the fixed pulleys 2121. When all the fixed pulleys 2121 are arranged along the same straight line direction, the portion of the connecting member 22 located between any two adjacent fixed pulleys 2121 has the same extension direction. When some of the fixed pulleys 2121 are arranged along the same straight line direction, the extension direction of the portion of the connecting member 22 located between two adjacent fixed pulleys 2121 can be specifically determined according to the direction of the axis connecting the two corresponding fixed pulleys 2121. At this time, the extension directions of each part of the connector 22 can be different, or only some parts can remain the same. This provides more flexible arrangement options for the traction mechanism 21, allowing its position to better match the shape of the support pile 1. When upgrading an existing charging pile to the charging pile described in this application, the traction mechanism 21 can adapt to the structure of the existing charging pile as much as possible, thereby reducing the change cost when upgrading the existing charging pile to the charging pile described in this application.

[0054] refer to Figure 4In some embodiments of this application, optionally, the traction mechanism 21 includes a first traction structure 211 and a second traction structure 212. The first traction structure 211 can specifically be a winding wheel 2111, a winding shaft, or other wound structure. Correspondingly, the connector 22 is a flexible structure, specifically a wire rope, chain, or similar structure. In idle conditions, the first traction structure 211 does not move; only the connector 22 applies a holding force to the suspended cable 3, allowing the suspended cable 3 to overcome its own weight and remain suspended. During use, the user can move the suspended cable 3 arbitrarily; the connector 22 adapts to the movement of the suspended cable 3, and the first traction structure 211 rotates in response to the movement of the connector 22. After use, the first traction structure 211 rotates to drive the connector 22 to retract and wrap around the first traction structure 211 until the suspended cable 3 can return to its initial position in the idle condition. The second traction structure 212 is rotatable relative to the support pile 1, and the connector 22 is simultaneously wound around the second traction structure 212. Specifically, the second traction structure 212 can be a fixed pulley 2121 or a shaft-like part. Part of the connecting member 22 is wrapped around the second traction structure 212, so that adjacent parts of the connecting member 22 located on different sides of the second traction structure 212 can have different extension directions. The first traction structure 211 adopts a rotatable structure, which helps to ensure the reliable movement of the connecting member 22. When the connecting member 22 is a flexible structure such as a rope, it is not easy to get tangled, stuck, or interfere with other structures. This helps to ensure the synchronization of the movement of the suspension cable 3 and the connecting member 22 when the user is charging, thereby improving the user's experience of the charging pile. Based on the setting of the second traction structure 212, the connecting member 22 can realize a more complex extension path while connecting the suspension cable 3 and the traction mechanism 21. This provides more and more flexible setting schemes for the arrangement of the traction mechanism 21, so that the setting position of the traction mechanism 21 can be better adapted to the shape of the support pile 1. When upgrading an existing charging pile to the charging pile described in this application, the traction mechanism 21 can be adapted to the structure of the existing charging pile as much as possible to reduce the change cost when upgrading the existing charging pile to the charging pile described in this application.

In this case, the first traction structure 211 can be a slider, a movable pulley 2115, or a similar structure, which can be specifically configured according to actual needs. The connecting member 22 is wound around the first traction structure 211, with one end fixedly connected to the support pile 1 and the other end connected to the suspension cable 3. In idle conditions, the first traction structure 211 does not move; only the connecting member 22 applies a holding force to the suspension cable 3, allowing the suspension cable 3 to overcome its own weight and remain suspended. During use, the user can move the suspension cable 3 arbitrarily, and the connecting member 22 moves to adapt to the movement of the suspension cable 3. The first traction structure 211 moves in accordance with the movement of the connecting member 22. After use, the first traction structure 211 moves to drive the connecting member 22 to move and reset, so that the suspension cable 3 can return to its initial position in the idle condition. The second traction structure 212 is rotatable relative to the support pile 1, and the connecting member 22 is simultaneously wound around the second traction structure 212. Specifically, the second traction structure 212 can be a fixed pulley 2121 or a shaft-like part, and part of the connecting member 22 is wrapped around the periphery of the second traction structure 212 so that adjacent parts of the connecting member 22 located on different sides of the second traction structure 212 can have different extension directions.

Based on the labor-saving and long-distance characteristics of the movable pulley 2115 system, when the user moves the suspension cable 3, the travel distance of the connecting member 22 will be much greater than the travel distance of the first traction structure 211. When the first traction structure 211 and the connecting member 22 are set inside the support pile 1, this helps to save space inside the support pile 1 and allows the first traction structure 211 and the connecting member 22 to better adapt to the internal space of the support pile 1. Meanwhile, under the same travel distance, the force required for the user to move the suspension cable 3 can be significantly reduced based on the aforementioned pulley 2115 system. This provides convenience for users and improves their experience with the charging station. Based on the second traction structure 212, the connector 22 can achieve a more complex extension path while connecting the suspension cable 3 and the traction mechanism 21. This provides more flexible placement options for the traction mechanism 21, allowing its position to better match the shape of the support pile 1. When upgrading an existing charging station to the charging station described in this application, the traction mechanism 21 can adapt to the existing charging station's structure as much as possible, reducing the cost of upgrading from an existing charging station to the charging station described in this application.

In this case, the first traction structure 211 may be a combination of a slider and a movable pulley 2115. A connecting member 22 is wound around the first traction structure 211, with one end fixedly connected to the support pile 1 and the other end connected to the suspension cable 3. In idle conditions, the first traction structure 211 remains stationary, applying a holding force to the suspension cable 3 only through the connecting member 22, allowing the suspension cable 3 to overcome its own weight and remain suspended. During use, the user can move the suspension cable 3 arbitrarily, and the connecting member 22 moves to adapt to the movement of the suspension cable 3. The first traction structure 211 moves in accordance with the movement of the connecting member 22. After use, the first traction structure 211 moves to drive the connecting member 22 to move and reset, allowing the suspension cable 3 to return to its initial position in the idle condition.

At the same time, the force required for the user to move the suspension cable 3 under the same travel distance can also be significantly reduced based on the aforementioned movable pulley 2115 system, thus providing convenience for users of the charging pile and improving their user experience. Based on the configuration of the second traction structure 212, the connector 22 can achieve a more complex extension path while connecting the suspension cable 3 and the traction mechanism 21. This provides more flexible configuration options for the traction mechanism 21, allowing its position to better match the shape of the support pile 1.

[0057] refer to Figure 10Alternatively, the first traction structure 211 may be slidable and rotatable relative to the support pile 1, and may specifically include a transmission component 2113 and a transmission wheel 2114. Two or more transmission wheels 2114 may be provided, with the transmission component 2113 surrounding and enclosing the circumference of all transmission wheels 2114. The transmission component 2113 may be a transmission chain, in which case the transmission wheels 2114 are specifically sprockets, and the transmission wheels 2114 mesh with the transmission component 2113. The transmission component 2113 may also be a transmission belt, in which case the transmission wheels 2114 are specifically pulleys, and the transmission wheels 2114 are in contact with the transmission component 2113. The transmission wheels 2114 are rotatable relative to the support pile 1 to drive the transmission component 2113 to move relative to the support pile 1. The connecting component 22 is fixedly connected to the transmission component 2113 by welding, fastener connection, or other means, so that the transmission component 2113 can drive the connecting component 22 to move relative to the support pile 1. The second traction structure 212 is fixedly connected to the support pile 1, and the connecting member 22 is slidable relative to the second traction structure 212. Specifically, the second traction structure 212 can be a guide rail 2122, a guide rod, or other structures.

The second traction structure 212 can be an independent structure, or it can be integrated into a single part with the structural beam or other mechanical structure within the support pile 1. Based on the belt drive or chain drive structure formed by the transmission member 2113 and the transmission wheel 2114, the first traction structure 211 can achieve smoother movement, which helps ensure the smoothness and reliability of the suspension cable 3 during resetting. By specifically controlling the size of the transmission wheel 2114, the first traction structure 211 can also meet different transmission ratio requirements. This improves the flexibility of the first traction structure 211, enabling it to be applied in traction mechanisms 21 with different transmission ratio requirements. The aforementioned connector 22 is slidably connected to the second traction structure 212. Based on the guiding effect of the second traction structure 212 on the connector 22, the connector 22 can more easily maintain its own movement trajectory.

Specifically, the winding wheel 2111 may have a rotating shaft, which is inserted into a mounting hole on the support pile 1 to allow the winding wheel 2111 to rotate relative to the support pile 1. Alternatively, the support pile 1 may have a rotating shaft, and the winding wheel 2111 may have a mounting hole. The rotating shaft is inserted into the mounting hole to allow the winding wheel 2111 to rotate relative to the support pile 1. The connecting member 22 may specifically be a flexible structure such as a wire rope or chain. The connecting member 22 is wound around the winding wheel 2111 by a winding method and extends or retracts as the winding wheel 2111 rotates. The second traction structure 212 includes a fixed pulley 2121, which may be spaced apart from the winding wheel 2111. The connector 22 is wound around the fixed pulley 2121 so that adjacent parts of the connector 22 on different sides of the fixed pulley 2121 can have different extension directions. When the suspension cable 3 moves, the connector 22 can move synchronously relative to the fixed pulley 2121. The fixed pulley 2121 rotates with the connector 22 under the action of friction, thereby reducing the frictional resistance experienced by the connector 22 during movement.

The power source 23 is connected to the traction mechanism 21, and the power source 23 can drive the traction mechanism 21 to move, so that the suspension cable 3 can be reset from the working position to the initial position. This can improve the automation level of resetting the suspension cable 3 of the charging pile, thereby improving the ease of use of the charging pile.

[0063] refer to Figure 9In some embodiments of this application, optionally, the power source 23 includes a motor 231, which is connected to the support pile 1, and the output shaft of the motor 231 is connected to the traction mechanism 21. The motor 231 can be directly fixedly connected to the connecting member 22 by welding, fastener connection, or other means, and the second traction structure 212 is used to constrain the movement direction of the connecting member 22. Alternatively, the motor 231 can also be connected to the winding wheel 2111 or the transmission wheel 2114 to drive the winding wheel 2111 or the transmission wheel 2114 to rotate. Exemplarily, the output shaft of the motor 231 is coaxially connected to the winding wheel 2111, and the connecting member 22 is specifically a suspension rope 222, with one end of the connecting member 22 connected to the winding wheel 2111 and the other end connected to the suspension cable 3. In idle conditions, neither motor 231 nor winding wheel 2111 operates. Motor 231 self-locks via its internal structure and applies a holding force to the suspended cable 3 via winding wheel 2111 and connector 22 to overcome the cable 3's own weight and keep it suspended. During use, the suspended cable 3 moves from its initial position to its working position. Connector 22 is pulled out to accommodate the cable 3's movement, and winding wheel 2111 rotates in response to the connector 22's movement, releasing the portion of connector 22 wound on winding wheel 2111. Simultaneously, motor 231 releases its self-lock and idles. After use, motor 231 drives winding wheel 2111 to rotate, which in turn drives connector 22 to retract and wind around winding wheel 2111, allowing the suspended cable 3 and connector 22 to return to their initial idle state.

[0064] refer to Figure 10 Alternatively, exemplarily, the output shaft of motor 231 is coaxially connected to transmission wheels 2114, with two transmission wheels 2114 arranged along the direction of gravity, and transmission component 2113 wound around the two transmission wheels 2114. Connector 22 is specifically a second sliding member 223, with one end fixedly connected to transmission component 2113 and the other end connected to suspension cable 3. In idle conditions, motor 231, transmission wheels 2114, and transmission component 2113 are all inactive. Motor 231 self-locks through its internal structure and applies a holding force to suspension cable 3 through transmission wheels 2114, transmission component 2113, and connector 22 to overcome the weight of suspension cable 3 and keep it suspended. During use, the suspension cable 3 moves from its initial position to its working position. The connector 22 moves to accommodate the movement of the suspension cable 3. The transmission component 2113 moves in accordance with the movement of the connector 22. The winding wheel 2111 rotates in accordance with the movement of the transmission component 2113. The motor 231 releases its self-lock and idles. After use, the motor 231 drives the transmission wheel 2114 to rotate. The transmission wheel 2114 drives the transmission component 2113 to move, which in turn drives the connector 22 to move, thus restoring the suspension cable 3 and the connector 22 to their initial state during idle operation.

[0065] refer to Figure 4 In some embodiments of this application, optionally, the power source 23 includes an elastic element 232, which may specifically be a coil spring (constant force spring) or a spring balancer, or other elastic structures. The first end of the elastic element 232 is connected to the support pile 1, and the second end of the elastic element 232 is connected to the traction mechanism 21. Exemplarily, the elastic element 232 may be a spring balancer, in which case the first end of the spring balancer is fixed to the support pile 1, and the second end of the spring balancer, as a pull-out end, can be directly and fixedly connected to the connecting member 22 by welding, fastener connection, or other means, or it may be connected to the first traction structure 211, such as the winding wheel 2111 or the first sliding member 2112.

[0066] refer to Figure 6 For example, the second end of the elastic element 232 can be directly connected to the connector 22121. In this case, the elastic element 232 is preferably used in combination with the aforementioned fixed pulley 2121. Two fixed pulleys 2121 are provided, spaced apart relative to each other in a horizontal direction or a direction inclined relative to the horizontal. The arrangement direction of the two fixed pulleys 232 can be specifically arranged according to the internal structural space of the support pile 1. By flexibly adjusting the arrangement direction of the two fixed pulleys 232, the traction mechanism 21 can be more spatially compatible with the support pile 1, thereby improving the overall space utilization and integration of the charging pile. One of the fixed pulleys 2121 and the elastic element 232 are spaced apart relative to each other along the direction of gravity. The spring in the elastic element 232 can be pulled out and automatically reset under its own elastic force, realizing the automatic release and retraction of the suspension cable 3. The connector 22 bypasses the two fixed pulleys 2121 and connects the elastic element 232 to the suspension cable 3. In idle conditions, the elastic element 232 remains stationary and applies a holding force to the suspended cable 3 via the connector 22, overcoming the cable's own weight and keeping it suspended. During use, the suspended cable 3 moves, and the connector 22 is pulled out to accommodate this movement, partially removing the elastic element 232. After use, the removed portion of the elastic element 232 automatically resets under internal elastic force, driving the connector 22 to retract, allowing the suspended cable 3 and connector 22 to return to their initial positions as in idle conditions. By adjusting the specifications and tension of the elastic element 232, or by using multiple elastic elements 232 in combination, the elastic element 232 can be adapted to different weight parameters of the suspended cable 3 and charging gun 4. This effectively counteracts the impact of the cable's and charging gun's weight on user operation, providing a near-zero-gravity charging experience.

[0067] refer to Figure 4For example, the second end of the elastic element 232 can be connected to the winding wheel 2111, and one end of the connector 22 is connected to the winding wheel 2111, while the other end is connected to the suspension cable 3. In idle conditions, neither the elastic element 232 nor the winding wheel 2111 moves. The elastic element 232 applies a holding force to the suspension cable 3 through the winding wheel 2111 and the connector 22 to overcome the weight of the suspension cable 3 and keep it suspended. In use, when the suspension cable 3 moves, the connector 22 is pulled out to accommodate the movement of the suspension cable 3, and the winding wheel 2111 rotates to accommodate the movement of the connector 22, causing a portion of the connector 22 wound on the winding wheel 2111 to be released. Simultaneously, a portion of the elastic element 232 is wound in the opposite direction onto the winding wheel 2111. After use, the elastic element 232 can retract the pulled-out portion and drive the winding wheel 2111 to rotate. The winding wheel 2111 can then drive the connector 22 to retract and wind around itself, allowing the suspension cable 3 and connector 22 to return to their idle state. This allows the elastic element 232 to adapt to different weight parameters of the suspension cable 3 and charging gun 4. This effectively counteracts the impact of the suspension cable 3 and charging gun 4's own weight on user operation, thus providing users with a near-zero-gravity charging experience.

[0068] refer to Figure 5 For example, the second end of the elastic element 232 can be connected to the first sliding element 2112. One end of the connecting element 22 bypasses the first sliding element 2112 and is fixedly connected to the support pile 1, while the other end is connected to the suspension cable 3. In an idle scenario, neither the elastic element 232 nor the first sliding element 2112 moves. The elastic element 232 applies a holding force to the suspension cable 3 through the first sliding element 2112 and the connecting element 22 to overcome the weight of the suspension cable 3 and keep it suspended. In use, the suspension cable 3 moves, and the connecting element 22 is pulled out to accommodate the movement of the suspension cable 3. The first sliding element 2112 moves in accordance with the movement of the connecting element 22, and simultaneously, a portion of the elastic element 232 is pulled out along with the movement of the first sliding element 2112. After use, the elastic element 232 can retract the pulled-out part and drive the first sliding element 2112 to reset. The first sliding element 2112 can drive the connector 22 to retract so that the suspension cable 3 and the connector 22 can return to the state of being idle.

[0069] The first sliding member 211 can slide along the slide rail, causing the spring of the elastic member 232 to be pulled out and extend along the sliding guide rail. After charging is completed, the elastic member 232 automatically rebounds, driving the spring to retract, realizing the automatic release and retraction of the suspended cable 3. Through the coordinated application of the fixed pulley 2121 and the movable pulley 2115 on the first sliding member 211, the direction of the pulling force and the length of the cable can be flexibly adjusted. By reasonably adjusting the specifications and pulling force of the elastic member 232, or by using multiple elastic members 232 in combination, it can be adapted to different weights of the suspended cables 3. This can effectively avoid the reverse curling phenomenon of the elastic member 232 and improve the service life of the spring of the elastic member 232. In addition, in the specific implementation process, this structure can reduce space occupation and be efficiently integrated with the charging pile structure by arranging the slide rail laterally or longitudinally.

[0070] refer to Figure 7 In some embodiments of this application, optionally, the power source 23 includes a counterweight 233, which is movable relative to the support pile 1 along the direction of gravity. The counterweight 233 is preferably used in combination with the aforementioned fixed pulley 2121. Specifically, two fixed pulleys 2121 are provided, spaced apart horizontally, and one of the fixed pulleys 2121 is spaced apart from the counterweight 233 along the direction of gravity. The counterweight 233 can move along the direction of gravity under the action of gravity, and the connector 22 passes around the two fixed pulleys 2121 and connects the counterweight 233 to the suspension cable 3. In idle situations, the counterweight 233 does not move and applies a holding force to the suspension cable 3 through the connector 22 to overcome the weight of the suspension cable 3 and keep it suspended. During use, the suspension cable 3 moves, and the connector 22 is pulled out to accommodate the movement of the suspension cable 3. The counterweight 233 rises as the connector 22 moves. After use, the counterweight 233 falls back under its own weight and drives the connector 22 to retract, allowing the suspension cable 3 and connector 22 to return to their idle state. During the retraction and extension of the suspension cable 3, the elastic element 232 will experience metal fatigue due to reciprocating motion, thus affecting its service life. By using the counterweight 233 as the power source 23, when the user uses the charging station, the suspension cable 3 drives the counterweight 233 to slide along the direction of gravity through the connector 22. During this process, the connector 22 can be guided by the fixed pulley 2121 to achieve flexible reversal of the pulling force. After charging is completed, the weight of the counterweight 233 drives the suspension cable 3 to reset, thereby achieving automatic retraction of the suspension cable 3.

[0071] In the aforementioned power source 23, the elastic element 232 and the counterweight 233 have simple and reliable structures, which helps ensure the reliability and service life of the charging pile. The elastic element 232 and the counterweight 233 do not generate additional energy consumption, and also help simplify the overall structure of the charging pile, reducing its structural and operational costs. The motor 231 is easier to control, better ensuring the movement accuracy and smoothness of the connecting part 22. Using any of the aforementioned power sources 23 can ensure the reliable movement of the traction mechanism 21, thereby ensuring the reliable movement of the suspension cable 3. The counterweight 233 can be made of common materials such as metal, brick, or sand to reduce its material cost, thus reducing the overall cost of the charging pile. The weight of the counterweight 233 can be flexibly set according to the self-weight of the suspension cable 3 on the charging pile. Since the counterweight 233 uses gravitational potential energy as its power source, there is no energy attenuation problem; therefore, using the counterweight 233 as a power source can also ensure the charging pile has excellent long-term stability.

[0072] refer to Figure 9 In some embodiments of this application, the connector 22 optionally includes a lifting ring 221. The lifting ring 221 is connected to the suspension cable 3. Specifically, the lifting ring 221 may include a flexible pad fitted around the suspension cable 3 and a clamp surrounding the flexible pad. The flexible pad protects the suspension cable 3 and increases the friction between the lifting ring 221 and the suspension cable 3, thereby hindering the movement of the lifting ring 221 on the suspension cable 3. The clamp clamps and secures the flexible pad and facilitates the connection of the lifting ring 221. The main body of the connector 22 can be connected to the clamp by welding, fastener connection, or bundling to ensure the reliability of the connection between the lifting ring 221 and the main body of the connector 22.

[0073] refer to Figure 9 The main body of the connector 22 may specifically include a lifting rope 222, which connects the lifting ring 221 to the first traction structure 211. Alternatively, the lifting rope 222 is wound around the second traction structure 212. Or, the lifting rope 222 connects the lifting ring 221 to the first traction structure 211, while also being wound around the second traction structure 212. The lifting rope 222 has a simple structure, good adaptability to complex trajectories, and can be better adapted to the traction mechanism 21.

[0074] refer to Figure 10 The main body of the connector 22 may also include a second sliding member 223, with the lifting ring 221 connected to the second sliding member 223. The second sliding member 223 is connected to the first traction structure 211, or slidably connected to the second traction structure 212, or simultaneously connected to both the first and second traction structures. The second sliding member 223 has a reliable movement trajectory and strong load-bearing capacity, effectively ensuring the stability and accuracy of the suspension cable 3's movement.

[0075] refer to Figure 11 , Figure 12 In some embodiments of this application, optionally, the suspension assembly 2 includes a swing arm structure 24, which is rotatably connected to the support pile 1. The swing arm structure 24 can suspend the suspension cable 3. The shape of the swing arm can be set according to actual needs, see reference. Figure 13 For example, the swing arm can be composed of one, two, or even more rigid rods rotatably connected. The swing arm has a certain degree of rigidity, which provides better load-bearing capacity for the suspended cable 3. Since the swing arm structure 24 can rotate relative to the support pile 1, it can adapt to the rotation caused by the movement of the connector 22 and the suspended cable 3, thus supporting the connector 22 and the suspended cable 3 while avoiding excessive constraint on them. In other words, this improves the suspension effect of the suspended cable 3 when it moves, while also ensuring the flexibility and smoothness of movement for both the suspended cable 3 and the connector 22.

[0076] In some embodiments of this application, optionally, the swing arm structure 24 can be connected to the suspension cable 3, or the swing arm structure 24 can also be connected to the connector 22, or the swing arm structure 24 can be connected to both the suspension cable 3 and the connector 22 simultaneously. Specifically, the rotation axis of the swing arm structure 24 extends along the direction of gravity, and at least one of the connector 22 and the suspension cable 3 is connected to the swing arm structure 24. The swing arm structure 24 can provide good support for the connector 22. Since the swing arm structure 24 can rotate relative to the support pile 1, it can adapt to the movement of the connector 22 and the suspension cable 3, thereby supporting the connector 22 and the suspension cable 3 while avoiding excessive constraint on them. In other words, this can improve the suspension effect of the suspension cable 3 when it moves, while also ensuring the flexibility and smoothness of movement of the suspension cable 3 and the connector 22.

[0077] In some embodiments of this application, optionally, at least a portion of the connecting member 22 passes through the swing arm structure 24, and the connecting member 22 can extend or retract relative to the swing arm structure 24. A reversing structure 241 is provided at the rotation axis of the swing arm structure 24. The reversing structure 241 can be a rotating shaft or a rotating wheel, and the connecting member 22 is wound around the reversing structure 241. (See reference...) Figure 13In some embodiments of this application, the swing arm structure 24 can be a single rod, in which case the swing arm structure 24 is rotatably connected to the support pile 1. Alternatively, the swing arm structure 24 can also be a joint structure formed by the rotatable connection of two or more rods. In this case, the part of the swing arm structure 24 closest to the support pile 1 can be fixedly or rotatably connected to the support pile 1, and the connecting member 22 protrudes from the part of the swing arm structure 24 furthest from the support pile 1. The swing arm structure 24 can provide good support for the connecting member 22. Since the swing arm structure 24 can extend or retract relative to the support pile 1, it can adapt to the deformation caused by the movement of the connecting member 22, so as to support the connecting member 22 while avoiding excessive constraint on the connecting member 22. The reversing structure 241 can prevent the connecting member 22 from jamming, so as to ensure the support effect on the connecting member 22, while also taking into account the flexibility and smoothness of the movement of the connecting member 22.

[0078] refer to Figure 1 , Figure 2 , Figure 3 In some embodiments of this application, optionally, the charging pile includes a charging gun 4, which is connected to a suspension cable 3 so that the suspension cable 3 can suspend the charging gun 4. The support pile 1 includes a cantilever portion 1a and a column portion 1b, which are arranged opposite to each other along a first direction Z. The suspension cable 3 passes through the charging gun 4 along the first direction Z towards the cantilever portion 1a. The column portion 1b is the part of the support pile 1 used to connect with the mounting base, which can be the ground or a mounting platform, mounting seat, or other structure corresponding to the support pile 1. The cantilever portion 1a is the part of the support pile 1 that extends away from the mounting base along its own extension direction. For ease of reference, the direction in which the cantilever portion 1a and the column portion 1b are arranged opposite each other is referred to as the first direction Z. In actual use, the first direction Z is in the same direction as the direction of gravity. The suspension cable 3 extends from the charging gun 4 along the first direction Z toward the cantilever 1a. In actual use, the suspension cable 3 extends from the charging gun 4 toward the upper part of the cantilever 1a of the support pile 1, thus preventing the end of the suspension cable 3 from drooping downwards near the charging gun 4. This avoids the possibility of the suspension cable 3 dragging on the ground from the side of the charging gun 4, further improving the suspension effect of the suspension cable 3. Based on the suspension of the suspension cable 3, wear and tear due to dragging on the ground can be minimized, while also providing convenience for the user. The improved floating effect of the suspension cable 3, due to it extending from the upper side of the charging gun 4, allows for better adaptation to the height of the vehicle charging port. This helps reduce the length of the suspension cable 3 and ensures the charging range covered by the suspension cable 3 and the charging gun 4. This improves the efficiency of the charging pile's management of the suspension cable 3 and the charging gun 4, while also enhancing the user experience of the charging pile.

[0079] The suspension cable 3 adopts a structure where the cable exits from the upper side of the charging gun 4 and the upper side of the connector 1c. This allows the suspension cable 3 to be guided upwards by gravity when the connector 22 connects to it. At this point, the suspension cable 3 forms an arch, with the connection between it and the connector 22 being the highest point, and the rest hanging straight downwards. This fully utilizes the advantages of the suspension assembly 2 and optimizes the path of the suspension cable 3. While meeting functional requirements, this effectively shortens the overall length of the suspension cable 3. Furthermore, because the suspension cable 3 exits from the upper side of the charging gun 4, the charging gun 4 can naturally fall to the car's charging port for connection under the suspension effect of the cable 3. This eliminates the need to pull the charging gun upwards from the ground, significantly improving the ease of use of the charging station.

[0080] When the connector 22 uses the suspension rope 222, the outlet point 51 extends upwards to the suspension point. When the user pulls the charging gun, the charging gun management structure releases the rope, resulting in two key effects: Firstly, the charging gun hanging point moves downwards, expanding the lateral span of the charging gun and thus extending the coverage of the charging operation; secondly, the charging gun management structure applies an upward pulling force, forming a dynamic balance with the weight of the charging gun, providing the user with a near-zero-gravity operating experience. During the retraction phase, the charging gun is pulled back into place and inserted back into the charging gun holder 52, maintaining its straightness and effectively preventing overlap or tangling during charging, achieving orderly and standardized management of the charging gun throughout the entire process without dragging on the ground. The charging gun remains suspended throughout the charging process, achieving structural neatness and order. The retractable top suspension device effectively expands the coverage of the charging interface, while the charging gun hanging vertically from the charging pile body significantly reduces the user's operational burden, providing a relaxed, efficient, and convenient charging experience.

[0081] refer to Figure 1 , Figure 2 , Figure 3 In some embodiments of this application, optionally, the support pile 1 includes the aforementioned cantilever portion 1a and column portion 1b. The cantilever portion 1a and column portion 1b are arranged opposite each other along the first direction Z, the suspension cable 3 passes through the column portion 1b at the first position 1d, and the connector 22 passes through the cantilever portion 1a at the second position 1e; the support pile 1 also has a second direction X and a third direction Y, the first direction Z, the second direction X, and the third direction Y intersect but are not coplanar.

[0082] The column portion 1b is provided with a connecting portion 1c, and a first position 1d is located on the side of the connecting portion 1c facing the cantilever portion 1a along the first direction Z. In other words, the suspension cable 3 passes through the connecting portion 1c along the first direction Z towards the cantilever portion 1a. When the first direction Z is the direction of gravity, since the suspension cable 3 passes through the upper position of the connecting portion 1c, the end of the suspension cable 3 near the connecting portion 1c will not tend to extend downward, thus avoiding the end of the suspension cable 3 near the connecting portion 1c from touching the ground. This can further improve the suspension effect of the suspension cable 3, so as to minimize the occurrence of the suspension cable 3 dragging on the ground. Based on the improvement of the levitation effect of the suspension cable 3 by passing through the upper side of the connecting portion 1c, the suspension cable 3 can be better adapted to the height of the vehicle charging port. This is beneficial to reducing the length of the suspension cable 3 and also to ensuring the charging range that the suspension cable 3 and the charging gun 4 can cover. This ensures the management efficiency of the charging pile for the suspension cable 3 and the charging gun 4, and also improves the user experience of the charging pile.

[0083] refer to Figure 3 In some embodiments of this application, optionally, along the first direction Z, the height of the support pile 1 is H1, the distance from the first position 1d to the end of the column portion 1b away from the cantilever portion 1a is H2, and the distance H2 from the first position 1d to the end of the column portion 1b away from the cantilever portion 1a is greater than or equal to 0.5H1, while H2 is less than or equal to H1, specifically it can be 0.5H1, 0.6H1, 0.7H1, 0.8H1, 0.9H1, 0.9H1, etc. This allows the suspension cable 3 to pass through the first position 1d of the column portion 1b at a height higher than or at the middle of the support pile 1 in the first direction Z, thereby avoiding the suspension cable 3 passing through the first position 1d of the column portion 1b at a height that is too low in the first direction Z, and further reducing the possibility of the suspension cable 3 dragging on the ground.

[0084] refer to Figure 2 In some embodiments of this application, optionally, the length of the overhang 1a along the second direction X is L1, where L1 specifically refers to the maximum external dimension of the overhang 1a in the second direction. The length of the column portion 1b is L2, where L2 specifically refers to the maximum external dimension of the column portion 1b in the second direction X. The length L1 of the overhang 1a is greater than or equal to 1.5L2 and less than or equal to 3L2, specifically it can be 1.5L2, 1.8L2, 2.1L2, 2.4L2, 2.7L2, 3L2, etc. This prevents the length of the overhang 1a from being too long, thereby improving the structural compactness of the charging pile and reducing the space occupied by the charging pile. This frees up more charging space for vehicles, allowing the charging pile to meet the charging needs of large vehicles.

[0085] refer to Figure 3In some embodiments of this application, optionally, along the first direction Z, the height of the support pile 1 is H1, and the distance from the second position 1e to the side of the column portion 1b away from the cantilever portion 1a is H3. The distance H3 from the second position 1e to the side of the column portion 1b away from the cantilever portion 1a is greater than or equal to 0.8H1 and less than or equal to H1, specifically it can be 0.8H1, 0.9H1, H1, etc. This allows the connector 22 to have sufficient height in the first direction Z at the second position 1e of the cantilever portion 1a, so that the connection between the connector 22 and the suspension cable 3 has sufficient height, thereby further improving the suspension effect of the connector 22 on the suspension cable 3.

[0086] refer to Figure 2 In some embodiments of this application, optionally, the length of the cantilever 1a along the second direction X is L1, where L1 specifically refers to the maximum external dimension of the cantilever 1a in the second direction X. The distance from the second position 1e to the side of the column portion 1b away from the suspension cable 3 is L3, and the distance L3 from the second position 1e to the side of the column portion 1b away from the suspension cable 3 is greater than or equal to 0.8L1 and less than or equal to 0.95L1, specifically it can be 0.8L1, 0.85L1, 0.9L1, 0.95L1, etc. This allows the connector 22 to pass through the second position 1e of the cantilever 1a away from the column portion 1b in the second direction X, so that the connector 22 can be connected to the middle or end of the suspension cable 3 as much as possible, thereby further improving the suspension effect of the suspension cable 3.

[0087] refer to Figure 2 In some embodiments of this application, optionally, the outer diameter of the suspension cable 3 is D, and the distance from the second position 1e to the side of the column portion 1b through which the suspension cable 3 passes along the second direction X is L4. The distance L4 from the second position 1e to the side of the column portion 1b through which the suspension cable 3 passes is greater than or equal to 5D and less than or equal to 10D, specifically 5D, 6D, 7D, 8D, 9D, 10D, etc. The bending radius of the existing suspension cable 3 at its initial position is generally 5D. Using the above-mentioned range for L4 allows the second position 1e to be compatible with the bending degree of the suspension cable 3. The connector 22 can be connected to the middle or end of the suspension cable 3 as much as possible, thereby further improving the suspension effect of the suspension cable 3.

[0088] refer to Figure 1In some embodiments of this application, optionally, the width of the cantilever 1a along the third direction Y is M1, where M1 specifically refers to the maximum external dimension of the cantilever 1a in the third direction Y. The width of the column part 1b is M2, where M2 specifically refers to the maximum external dimension of the column part 1b in the third direction Y. The width M1 of the cantilever 1a is greater than or equal to 0.8 times the width M2 of the column part 1b, and simultaneously the width M1 of the cantilever 1a is greater than or equal to 10 times the width M2 of the column part 1b, specifically it can be 0.8M2, M2, M2, 3M2, 4M2, 5M2, 6M2, 7M2, 8M2, 9M2, 10M2, etc. In existing charging piles, the width of the cantilever 1a can reach 11 times the width of the column part 1b. However, the charging pile described in this application, based on the flexible arrangement of the suspension component 2, can be arranged relatively smaller. This can save the space occupied by the charging pile and improve the layout flexibility of the charging pile.

[0089] Secondly, embodiments of this application provide a charging system, which includes any of the aforementioned charging piles.

[0090] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
