Description

Technical Field

[0001] This application relates to the field of new energy technology, specifically to a cable retractor and a charging pile. Background Technology

[0002] With increasingly stringent requirements for energy conservation and environmental protection, the popularity of new energy vehicles is also growing. As an important device for replenishing energy for new energy vehicles, charging piles are receiving more and more attention for their service life and ease of maintenance.

[0003] Currently, in order to adapt to the charging port positions of different car models, the charging gun cable is generally designed to be quite long. This makes the cable very easy to be dragged on the ground and subjected to friction, crushing, or trampling, which can easily damage the cable and affect the service life of the charging station.

[0004] In response, some charging stations are equipped with cable retractors to house the cables and prevent them from being damaged. However, most cable retractors are already tightly connected to the cables during production and assembly. If either the cable retractor or the cable is damaged, the entire device needs to be disassembled for maintenance or replacement, making the maintenance process cumbersome, time-consuming, and labor-intensive. Summary of the Invention

[0005] In view of the above problems, this application provides a cable reel and a charging pile, which can improve the service life of the cable and facilitate the disassembly and maintenance of the cable reel and the cable separately.

[0006] According to one aspect of the embodiments of this application, a cable winding device is provided for installation in the cabinet of a charging pile to manage the cables of the charging pile. The charging pile also includes a charging gun. One end of the cable is connected to the cabinet and extends from the mounting surface of the cabinet at a preset angle, and the other end is connected to the charging gun. The cable winding device includes: an elastic support rod and a cable bundler; one end of the elastic support rod is used to connect to the cabinet and forms a preset angle with the mounting surface, and the other end is connected to the cable bundler. The cable bundler is provided with a cable through hole for the cable to pass through, and the elastic support rod is connected to one side of the cable bundler along the radial direction of the cable through hole. The elastic support rod is configured to be detachable from the cable; the elastic support member is used to support the portion of the cable located between the cabinet and the cable bundler when the cable is not under force, so that the portion of the cable located between the cabinet and the cable bundle is in a state substantially parallel to the elastic support rod; the elastic support rod is also used to bend and elastically deform with the cable when the cable is pulled under force, so as to increase the cable insertion distance into the charging gun.

[0007] In one alternative configuration, the flexible support rod is detachably connected to the cable tie.

[0008] In one alternative embodiment, the flexible support rod includes a flexible section and a rigid section. One end of the flexible section is used for fixed connection with the cabinet, and the other end is connected to the rigid section. The end of the rigid section opposite to the flexible section is connected to the cable bundle.

[0009] In one alternative approach, the elastic support rod is a spring that is elastic throughout its entire length.

[0010] In one alternative approach, the cross-sectional area of ​​the spring is configured to gradually decrease from the end connected to the cabinet to the end connected to the cable tie, so that the bending strength of the spring gradually decreases from the end connected to the cabinet to the end connected to the cable tie.

[0011] In one alternative embodiment, the cable take-up device further includes a limiting sleeve for detachably engaging with the elastic support rod and the portion of the cable located between the cabinet and the cable bundle, respectively, to secure the portion of the cable located between the cabinet and the cable bundle to the elastic support rod.

[0012] In one alternative embodiment, the cable tie includes an arc-shaped sleeve with an arc-shaped cable passage hole formed inside the sleeve; the cable tie also includes a first connector and a second connector, the first connector being detachably connected to an elastic support rod, the second connector being detachably connected to the sleeve, and the first connector and the second connector being detachably connected.

[0013] In one alternative embodiment, a notch is provided on one side of the first radial direction of the elastic support rod on the first connector, and first sliding connecting portions are provided on opposite sides of the second radial direction of the elastic support rod on the first connector. The first sliding connecting portions extend axially along the elastic support rod, wherein the first radial direction, the second radial direction, and the axis of the elastic support rod are mutually perpendicular to each other. The second connector is U-shaped, and second sliding connecting portions extending axially along the inner walls of opposite sides of the second radial direction of the elastic support rod are provided. The second sliding connecting portions slide and engage with the first sliding connecting portions axially along the elastic support rod, so that the second connector is engaged with the first connector and covers the notch. A portion of the inner wall of the second connector and the first connector enclose the inner wall of the notch to form a first wire passage hole. A second wire passage hole is formed inside the sleeve. The first wire passage hole and the second wire passage hole together form a wire passage hole, and the first wire passage hole and the second wire passage hole are used for the cable to pass through sequentially.

[0014] In one alternative embodiment, the first connector is provided with a connection hole for the end of the elastic support rod facing away from the cabinet to be inserted and fixed; the end of the second connector covering the notch extends to form a plug-in wall, which is inserted into the second cable hole and fixedly connected to the sleeve.

[0015] According to another aspect of the embodiments of this application, a charging pile is also provided, including: a cabinet, a cable, a charging gun, and a cable winding device as described above, wherein one end of the cable is connected to the cabinet and the other end is connected to the charging gun, and the cable winding device is connected to the cabinet and the cable respectively.

[0016] The cable winding device provided in this application sets the angle between the mounting surface on the cabinet and the elastic support rod and cable to be the same, and connects the end of the elastic support rod away from the cabinet to the side of the cable tie located at the cable passage hole. This allows the elastic support rod to lift the portion of the cable located between the cabinet and the cable tie in its default state, making it parallel to the elastic support rod, thus suspending the entire cable and preventing wear and tear or crushing caused by the cable dragging on the bottom surface. Furthermore, since the elastic support rod and cable are not directly connected, the cable winding device provided in this application also allows for detachable separation of the elastic support rod and cable, enabling convenient and individual disassembly of either the elastic support rod or the cable. This improves the efficiency of later maintenance of the charging pile and reduces maintenance costs.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0043] Charging stations typically employ either a winding or support-type cable take-up device. The winding type has a winding roller inside or on the cabinet, with the cable wound around it. During charging, pulling the charging gun at the cable end causes the winding roller to rotate clockwise, extending the cable to the required connection length. After charging, the winding roller automatically rotates in the opposite direction, causing the cable to retract and wind back onto the roller, completing the take-up process. The support-type take-up device uses a flexible sleeve on the cabinet, with part of the cable passing through it. During charging, pulling the charging gun at the cable end bends the sleeve, increasing the cable's connection distance to the required length. After charging, releasing the cable allows it to be pulled back by the elastic return of the sleeve, completing the take-up process.

[0044] Both the aforementioned winding-type and support-type cable reel-up devices require a reliable connection to the cable during the charging pile's production and assembly. They cannot be used to add a cable reel-up device to existing charging piles that lack one. Furthermore, neither the winding-type nor the support-type cable reel-up devices allow for separate removal of the device or cable from the cabinet. Removing either requires disassembling both simultaneously and then separating them, making individual cable or cable maintenance cumbersome and inefficient.

[0045] To address the aforementioned issues, this application proposes a support-type cable retraction device. One end of an elastic support rod is connected to a server rack, with the angles between the elastic support rod and the rack's mounting surface, as well as between the cable and the rack's mounting surface, set to be the same. The cable passes through a cable tray connected to the end of the elastic support rod away from the rack via a cable hole. The elastic support rod is then connected to the cable tray on one side radially along the cable hole. Initially, the elastic support rod supports the cable tray, ensuring that the portion of the cable between the rack and the cable tray is approximately parallel to the elastic support rod, thus supporting the cable and achieving cable retraction. During charging, pulling the cable causes stress on the cable tray and the elastic support rod. The elastic support rod deforms and bends, and the cable tray shifts, increasing the cable's connection distance to meet the required insertion gun distance. After charging is complete, the elastic support rod returns to its original position, again supporting the cable and preventing wear, pressure, or other damage that could affect its lifespan. Furthermore, since the flexible support rod is configured to be detachable from the cable, when the flexible support rod needs to be disassembled and maintained separately, it can be detached from the cable and removed from the rack without any cable disassembly or reassembly, ensuring convenient individual maintenance or replacement of the flexible support rod. Similarly, when the cable needs to be disassembled and maintained separately, the support rod and cable are detached, and the cable can then be removed for maintenance, ensuring the same efficiency for individual cable maintenance operations.

[0046] Please refer to the details. Figure 1 and Figure 2 , Figure 1 The diagram illustrates the structure of a charging pile with a cable retractor according to an embodiment of this application. Figure 2The figure shows a partial structure of a charging pile with a cable winding device. As shown, the cable winding device 100 is installed in the cabinet 510 of the charging pile 500 to manage the cables 520 of the charging pile 500. The charging pile 500 also includes a charging gun 530. One end of the cable 520 is connected to the cabinet 510 and extends from the mounting surface 5111 of the cabinet 510 at a preset angle, and the other end is connected to the charging gun 530. The cable winding device 100 includes a flexible support rod 110 and a cable bundle 120. One end of the flexible support rod 110 is connected to the cabinet 510 and forms the aforementioned preset angle with the mounting surface 5111, and the other end is connected to the cable bundle 120. The cable bundle 120 is provided with a cable through hole 121 for the cable 520 to pass through, and the flexible support rod 110 is connected to one side of the cable bundle 120 along the radial direction of the cable through hole (in the direction shown by the X-axis in the figure). The elastic support rod 110 is configured to be detachable from the cable 520. Specifically, the elastic support rod 110 can be detachably connected to the cable bundle 120 so that the elastic support rod 110 and the cable 520 can be detachably separated. Alternatively, the cable bundle 120 itself can include two detachable parts. By separating these two parts, the cable bundle 120 can be separated from the cable 520, thereby achieving the detachment of the elastic support rod 110 and the cable 520.

[0047] like Figure 3 As shown from a frontal view, the elastic support rod 110 is used to support the portion of the cable 520 located between the cabinet 510 and the cable tie 120 when the cable 520 is not under stress, so that the portion of the cable 520 located between the cabinet 510 and the cable tie 120 is approximately parallel to the elastic support rod 110. When the cable 520 is not under stress: the elastic support rod 110 is only subjected to its own weight and is pulled by the weight of the cable 520 and the charging gun 530. At this time, the elastic support rod 110 extends approximately vertically. Understandably, because the cable 520 itself is easily deformable, the portion of the cable 520 located between the cabinet 510 and the cable tie 120 may, due to assembly, tolerances, etc., cause the cable 520 to extend non-linearly or tilted towards the preset extension direction. At this point, the portion of cable 520 located between cabinet 510 and cable tie 120 is not absolutely parallel to the elastic support rod 110, but the portion of cable 520 located between cabinet 510 and cable tie 120 is approximately parallel to the elastic support rod 110.

[0048] like Figure 4 As shown in the frontal view, the elastic support rod 110 is also used to bend and elastically deform with the cable 520 when the cable 520 is pulled by force, so as to increase the insertion distance of the cable 520.

[0049] In the specific embodiment shown in the figure, the cabinet 510 includes a cabinet body 512 and a gun socket 511. The mounting surface 5111 is disposed on the gun socket 511. The cable 520 and the elastic support rod 110 are both vertically connected to the mounting surface 5111 of the gun socket 511. The gun socket 511 is installed and fixed on the cabinet body 512, so that the cable 520 and the elastic support rod 110 are indirectly fixed to the cabinet body 512. This method allows the cable part to form an independent module. During the assembly process of the charging pile 500, this independent module can be assembled first and then assembled into a whole on the cabinet 510, realizing the modular assembly of the charging pile 500, which is beneficial to improving the assembly efficiency of the charging pile 500.

[0050] Regarding the connection structure between the elastic support rod 110 and the gun holder 511, this application proposes an embodiment, please refer to [link / reference needed]. Figure 5 As shown in the figure, the gun holder 511 is provided with a mounting hole 5112, and a mounting screw 5113 is fixedly installed in the mounting hole 5112. One end of the elastic support rod 110 is provided with a spring mounting post 1101. One end of the spring mounting post 1101 can be fixedly connected to the elastic support rod 110 by means of riveting, snap-fitting, threaded connection, etc., and the other end is threadedly connected to the mounting screw 5113, so that the elastic support rod 110 can be detachably fixed to the gun holder 511. This installation method can facilitate the disassembly, assembly and maintenance of the elastic support rod 110.

[0051] Of course, in some other embodiments, the mounting surface 5111 can also be the surface of the cabinet 512, and the cable 520 and the elastic support rod 110 can directly form a preset angle with the surface of the cabinet 512, or the cable 520 and the elastic support rod 110 can also be indirectly fixed to the cabinet 512 through the mounting surface connected to other bases that are not gun sockets.

[0052] In addition, the aforementioned preset angle can be used for Figures 1 to 4 In addition to the 90° provided in the illustrated embodiment, it can also be any angle within 0-360°. That is, the cable 520 and the elastic support rod 110 can be arranged parallel to the mounting surface 5111, or they can be arranged at an acute angle, a right angle, or an obtuse angle.

[0053] In its default state, the elastic support rod 110 can be as follows: Figure 2 and Figure 3The cable 520 is shown extending vertically (in the direction indicated by the Z-axis in the figure). This allows the cable 520 to be suspended. When the cable 520 is long, this helps to minimize the contact area between the cable 520 and the ground. When the cable 520 is short, it can completely avoid contact with the ground, ensuring the stability of the cable 520 and extending its service life. It is understood that in some other embodiments, the elastic support rod 110 can also extend at an angle in its default state; this is not limited here.

[0054] like Figure 3 In the state shown, when the charging pile 500 is not in operation, the charging gun 530 is inserted into the charging gun socket 511, the elastic support rod 110 is in a default straight state, and the part of the cable 520 located between the charging gun socket 511 and the cable tie 120 is in a straight state parallel to the elastic support rod 110, so that the cable 520 is suspended and does not drag on the ground.

[0055] like Figure 4 As shown, when charging is required, the user unplugs the charging gun 530 from the charging gun socket 511. If the charging gun distance is insufficient, the user can pull the charging gun 530 to press the cable 520 down onto the elastic support rod 110. The elastic support rod 110 will then undergo elastic deformation and bend, increasing the horizontal length of the cable 520 to meet the charging gun distance required for new energy vehicles.

[0056] For the detachable connection between the elastic support rod 110 and the cable bundle 120, the elastic support rod 110 and the cable bundle 120 can be detachably connected by riveting, threaded fasteners, snap-fit, etc., without limitation. However, considering that the elastic support rod 110 needs frequent bending and deformation, it is prone to damage after prolonged use. Therefore, when the elastic support rod 110 needs to be disassembled separately for maintenance or replacement, one end of the elastic support rod 110 can be first detached from the cable bundle 120, and then the other end of the elastic support rod 110 can be detached from the cabinet 510. The elastic support rod 110 can then be removed individually without any operation on the cable 520, making disassembly easy and convenient. Furthermore, considering that the cable 520 is the main component for current transmission in the charging circuit, regular disassembly and maintenance of the cable 520 is essential to ensure the safety and reliability of charging. When it is necessary to disassemble cable 520 separately, first separate cable bundle 120 from elastic support rod 110, and then disconnect the end of cable 520 that is connected to cabinet 510. Cable 520 can then be removed separately for maintenance or replacement. Although cable bundle 120 is still attached to cable 520 after removal, cable bundle 120 can be easily removed from the end of cable 520 that was originally connected to cabinet 510, so as not to cause any difficulty in the disassembly operation of cable 520.

[0057] For the cable tie 120, which comprises two detachable parts, one part is connected to the elastic support rod 110, and the other part is detachably connected to the first part. This connection can be achieved through riveting, threaded fasteners, or snap-fitting. When it is necessary to disassemble the elastic support rod 110 or the cable 520 separately, the two parts of the cable tie 120 are first disassembled from each other. Then, the end of the elastic support rod 110 connected to the cabinet 510 or the end of the cable 520 connected to the cabinet 510 is disconnected, thus allowing for the individual disassembly of the elastic support rod 110 or the cable 520.

[0058] In summary, the cable reeling device 100 provided in this application sets the angle between the mounting surface 5111 on the cabinet 510, the elastic support rod 110, and the cable 520 to be the same, and connects the end of the elastic support rod 110 away from the cabinet 510 to the side of the cable bundle 120 located at the cable passage hole 121. This allows the elastic support rod 110 to, in its default state, support the portion of the cable 520 located between the cabinet 510 and the cable bundle 120, making it parallel to the elastic support rod 110. This suspends the cable 520 as a whole, preventing wear and tear or crushing caused by dragging on the bottom surface. Furthermore, since the elastic support rod 110 and the cable 520 are not directly connected, the cable reeling device 100 provided in this application also allows for detachable separation of the elastic support rod 110 and the cable 520, enabling convenient individual disassembly of either the elastic support rod 110 or the cable 520. This improves the efficiency of later maintenance of the charging pile and reduces maintenance costs.

[0059] For long cables, considering that if the elastic support rod has a strong elastic deformation capacity, it will bend to some extent under the influence of the weight of the cable and cable tie in its default state, which may prevent the cable from being fully retracted. To address this, this application further proposes an implementation method, which can be found again in the following description. Figure 2 As shown in the figure, the elastic support rod 110 includes an elastic section 111 and a rigid section 112. One end of the elastic section 111 is fixedly connected to the cabinet 510, and the other end is connected to the rigid section 112. The end of the rigid section 112 facing away from the elastic section 111 is connected to the cable tie 120.

[0060] As the name suggests, the bending strength of the elastic segment 111 is less than that of the rigid segment 112. The bending strength refers to the maximum stress that a material can withstand when it breaks under bending load or reaches a specified bending moment, which is the material's ability to resist bending. The greater the bending strength, the less likely the material is to bend, and the smaller the bending strength, the easier the material is to bend.

[0061] By configuring the elastic support rod 110 to include an elastic section 111 and a rigid section 112, for cases where the cable 520 is long, the elastic section 111 provides bending deformation to allow the cable 520 to reach the required insertion distance when charging is required. When not charging, the elastic section 111 retracts the cable 520 and the rigid section 112 provides reliable support for the cable 520, ensuring that the cable 520 does not drag on the ground.

[0062] For cases where the cable is short, in order to easily pull the cable to achieve the required insertion distance, this application also proposes an implementation method in which the elastic support rod 110 is a spring with elasticity throughout its entire length. Using a spring with elasticity throughout its entire length allows the elastic support rod 110 to bend and deform more easily, providing a retraction effect for the shorter cable 520 while allowing the user to easily pull the cable 520 to move the elastic support rod 110 to achieve the required insertion distance.

[0063] Regarding the embodiment where the elastic support rod 110 is entirely made of springs, in order to improve its support strength for cables, this application further proposes an implementation method. Specifically, the cross-sectional area of ​​the spring is configured to gradually decrease from the end connected to the cabinet 510 to the end connected to the cable tie 120, so that the bending strength of the spring gradually decreases from the end connected to the cabinet 510 to the end connected to the cable tie 120. That is, the end of the spring connected to the cable tie 120 is easier to bend, while the end connected to the cabinet 510 is less likely to bend.

[0064] This configuration provides reliable support to the cable 520 via the portion of the spring near the cabinet 510, preventing excessive bending and ensuring reliable cable winding. Simultaneously, the gradually decreasing bending strength from the end connected to the cabinet 510 to the end connected to the cable tie 120 allows the bending strength of the spring to better match the deformation trend of the cable 520. Specifically, it prioritizes bending at the cable tie 120, and the cable 520 becomes increasingly less prone to bending from the cable tie 120 to the cabinet 510. Therefore, when the charging distance only requires bending at the cable tie 120, the remaining portion of the cable 520 between the cable tie 120 and the cabinet 510 will not bend significantly, ensuring effective cable winding during charging.

[0065] When the elastic support rod 110 is extending vertically, if the cable 520 is heavy, the portion of the cable 520 located between the cabinet 510 and the cable tie 120 may slide downwards under its own weight, causing more of the cable 520 to slide between the cabinet 510 and the cable tie 120 and bend, which may easily cause the cable 520 to bend excessively and be damaged.

[0066] To address the aforementioned issues and ensure the reliability of the elastic support rod's support for the cable, this application proposes an implementation method, which can be found in the following description. Figure 2 As shown in the figure, the cable take-up device 100 also includes a limiting sleeve 130, which is used to detachably connect to the elastic support rod 110 and the portion of the cable 520 located between the cabinet 510 and the cable bundle 120, respectively, so as to fix the portion of the cable 520 located between the cabinet 510 and the cable bundle 120 to the elastic support rod 110.

[0067] Specifically, the limit sleeve 130 can be set with only one, or as follows: Figure 2 Multiple limiting sleeves are provided to adequately limit the cable 520. Regarding the method by which the limiting sleeve 130 is detachably connected to the elastic support rod 110 and the cable 520, this application provides an embodiment; please refer to the following for details. Figure 6 The figure shows the structure of the limiting sleeve 130. As shown, the limiting sleeve 130 includes a first sleeve body 131 and a second sleeve body 132. Both the first sleeve body 131 and the second sleeve body 132 have two socket notches. The first sleeve body 131 and the second sleeve body 132 are used to fasten to the elastic support rod 110 and the cable 520 from both sides, so that the two socket notches on the first sleeve body 131 and the two socket notches on the second sleeve body 132 correspond one-to-one to form two socket holes 133. One socket hole 133 is fitted onto the outer periphery of the elastic support rod 110, and the other socket hole 133 is fitted onto the outer periphery of the cable 520. The first sleeve body 131 and the second sleeve body 132 have fixing holes 1321 facing each other. The second sleeve body 132 and the first sleeve body 131 are fixedly connected by fasteners (such as rivets, screws, etc.) passing through the fixing holes 1321 on the second sleeve body 132 and the first sleeve body 131 in sequence. Of course, the first set 131 and the second set 132 can also be fastened together by a snap-fit ​​or other structure.

[0068] It should be noted that the above is only one embodiment of the limiting sleeve 130 provided in this application. In other embodiments, the limiting sleeve 130 may also be a rope or the like that which loops the cable 520 and the elastic support rod 110 together, as long as it can achieve mutual limiting of the cable 520 and the elastic support rod 110. No limitation is made here.

[0069] By using a limiting sleeve 130 to reliably limit the portion of the cable 520 located between the cabinet 510 and the cable tie 120 and the elastic support rod 110, the damage to the cable 520 caused by more of it sliding between the cabinet 510 and the cable tie 120 and bending, as mentioned above, can be avoided. At the same time, since the limiting sleeve 130 is detachably fitted onto the cable 520 and the elastic support rod 110, when it is necessary to disassemble the cable 520 or the elastic support rod 110 separately, the limiting sleeve 130 can be removed first without affecting the individual disassembly of the cable 520 or the elastic support rod 110.

[0070] To avoid cable breakage due to excessive bending, this application also proposes an implementation method, which can be found again in detail. Figure 2 As shown in the figure, the cable tie 120 includes an arc-shaped sleeve 122, and an arc-shaped cable passage hole 121 is formed inside the sleeve 122.

[0071] The arc-shaped cable hole 121 can guide the cable 520 passing through it, so that the portion of the cable 520 at the sleeve 122 extends outward in a shape greater than the minimum bending curvature of the cable 520, thereby effectively protecting the cable 520 and preventing damage such as excessive bending of the cable 520.

[0072] Regarding the connection structure between the cable tie and the elastic support rod, this application proposes one embodiment; please refer to the details below. Figure 7 The figure shows the structure of the cable tie 120 connected to the elastic support rod. As shown in the figure, the cable tie 120 also includes a first connector 123 and a second connector 124. The first connector 123 is detachably connected to the elastic support rod 110, the second connector 124 is detachably connected to the sleeve 122, and the first connector 123 and the second connector 124 are detachably connected.

[0073] Specifically, the first connector 123 and the elastic support rod 110, the second connector 124 and the sleeve 122, and the first connector 123 and the second connector 124 can all be detachably connected to each other by means of riveting, snap-fitting, threaded fastener connection, etc., without being limited here.

[0074] The first connector 123 and the second connector 124 serve as intermediate connecting components to detachably fix the elastic support rod 110 and the sleeve 122 together. Thus, when it is necessary to disassemble the elastic support rod 110 or the cable 520 separately, no operation needs to be performed on the elastic support rod 110 or the sleeve 122. Only the first connector 123 and the second connector 124 need to be disassembled and separated. This can avoid damage to the elastic support rod 110 or the sleeve 122 due to improper operation during disassembly. Since the first connector 123 and the second connector 124 are low cost, when they are damaged due to frequent disassembly and assembly, the first connector 123 and the second connector 124 can be directly replaced.

[0075] Regarding the specific connection method between the first connector and the second connector, this application further proposes an embodiment, please refer to the following for details. Figure 7 and further combine Figure 8 and Figure 9 , Figure 8 The diagram shows the structure after the first and second connectors are fitted together. Figure 9 The figure shows the structure after the first and second connectors are separated. As shown, the first connector 123 has a notch 1231 on one side along the first radial direction of the elastic support rod (shown by the X-axis in the figure), and first sliding connecting portions 1232 are provided on opposite sides along the second radial direction of the elastic support rod (shown by the Y-axis in the figure). The first sliding connecting portions 1232 extend along the axial direction of the elastic support rod (shown by the Z-axis in the figure). The second connector 124 is U-shaped, and its inner walls on both sides along the Y-axis in the figure have second sliding connecting portions 1241 extending along the Z-axis in the figure. The second sliding connecting portions 1241 and the first sliding connecting portions 1232 slide in cooperation along the Z-axis in the figure, so that the second connector 124 engages with the first connector 123 and covers the notch 1231. Part of the inner wall of the second connector 124 and the inner wall of the first connector 123 at the notch 1231 form a first wire passage hole 1211. The inside of the sleeve 122 forms a second wire passage hole 1212. The first wire passage hole 1211 and the second wire passage hole 1212 together form a wire passage hole 121, and the first wire passage hole 1211 and the second wire passage hole 1212 are used for the cable 520 to pass through in sequence.

[0076] Specifically, the sliding fit between the first sliding connection part 1232 and the second sliding connection part 1241 can be achieved by mechanisms such as the fit between the slide groove and the slider, the fit between the slide rail and the slider, or the fit between the slide rail and the pulley.

[0077] exist Figure 8 and Figure 9In the illustrated embodiment, the side wall of the second connector 124 is further provided with a limiting fixing hole 1242, and the outer wall of the first connector 123 is correspondingly provided with a threaded hole 1233. After the first sliding connection portion 1232 and the second sliding connection portion 1241 slide into place, the first connector 123 and the second connector 124 can be fixed to each other by means of a threaded fastener passing through the limiting fixing hole 1242 and threadedly connecting to the threaded hole 1233. In addition, in other embodiments, the first connector 123 and the second connector 124 can also be fixed to each other by means of a pin engagement or other similar methods.

[0078] First, the first connector 123 and the second connector 124 are slidably coupled along the axial direction of the elastic support rod. This ensures that when the elastic support rod 110 and the sleeve 122 are disassembled, the corresponding components move along the axial direction of the elastic support rod. Since the portion of the cable 520 located between the sleeve 122 and the cabinet 510 is parallel to the elastic support rod, the corresponding components also move along the cable axial direction. This prevents the cable or elastic support rod from becoming difficult to operate or even damaged due to radial pulling. Second, the slidable coupling along the axial direction of the elastic support rod also restricts the radial movement of the first connector 123 and the second connector 124, ensuring the stability of the connection between the elastic support rod 110 and the sleeve 122. Finally, after the second connector 124 slides and is fixed to the first connector 123, the inner wall of the second connector 124 and the inner wall of the first connector 123 at the notch 1231 form a first wire hole 1211 to guide and limit the cable 520, which can further improve the support stability of the cable 520.

[0079] Regarding the connection structure between the first connector and the elastic support rod, and the connection structure between the second connector and the sleeve, this application further proposes an embodiment, please refer to the following for details. Figures 7 to 9 and further combine Figure 10 , Figure 10 The figure shows the connection structure between the sleeve and the elastic support rod from another perspective. As shown, the first connector 123 is provided with a connection hole 1234, which is used for the end of the elastic support rod 110 facing away from the cabinet 510 to pass through and be fixed. The end of the second connector 124 covering the notch 1231 extends to form a plug-in wall 1243, which is inserted into the second cable hole 1212 and fixedly connected to the sleeve 122.

[0080] Specifically, after the elastic support rod 110 is inserted into the connecting hole 1234, it can be fixed by riveting, snap-fitting, threaded fastener connection, etc. Similarly, after the insertion wall 1243 is inserted into the second wire passage hole 1212, it can also be fixed by one or more of these methods. Figure 7 and Figure 10 In the specific embodiment shown, after the insertion wall 1243 is inserted into the second wire hole 1212, the sleeve 122 is clamped and fixed to the insertion wall 1243 by fitting a clamp 1244 around the outer periphery of the sleeve 122 and tightening it, thereby realizing the assembly and fixation of the second connector 124 and the sleeve 122.

[0081] In this embodiment, by inserting and fixing the elastic support rod 110 into the connecting hole 1234, the inner wall of the connecting hole 1234 can reliably limit the elastic support rod 110 radially. This facilitates bending deformation of the elastic support rod 110 and ensures the stability of the connection. Similarly, by inserting and fixing the insertion wall 1243 into the second cable passage hole 1212, the inner wall of the second cable passage hole 1212 can reliably limit the second connector 124 radially along the cable, thereby ensuring the stability of the cable support.

[0082] According to another aspect of the embodiments of this application, a charging pile is also provided; please refer again for details. Figure 1 As shown in the figure, the charging pile 500 includes a cabinet 510, a cable 520, a charging gun 530, and a cable winding device 100 provided in any of the above embodiments. One end of the cable 520 is connected to the cabinet 510, and the other end is connected to the charging gun 530. The cable winding device 100 is connected to the cabinet 510 and the cable 520 respectively.

[0083] In the specific embodiment shown in the figure, the cabinet 510 includes a cabinet body 512 and a charging gun socket 511. One end of the cable 520 and the elastic support rod 110 are both connected to the charging gun socket 511, and the charging gun socket 511 is fixed to the cabinet body 512. This allows the cable 520 and the elastic support rod 110 to be indirectly fixed to the cabinet body 512. This method allows the cable section to form an independent module. During the assembly of the charging pile 500, this independent module can be assembled first and then assembled onto the cabinet 510 as a whole, realizing the modular assembly of the charging pile 500 and improving the assembly efficiency of the charging pile 500. Of course, in other embodiments, the cable 520 and the elastic support rod 110 can also be directly fixed to the cabinet body 512; this is not limited here.

[0084] The charging pile 500 provided in this application embodiment uses the cable winding device 100 in any of the above embodiments to wind up the cable 520. This not only avoids the cable 520 from being worn or crushed due to dragging on the bottom surface, but also allows for easy disassembly of the elastic support rod 110 or the cable 520, thereby improving the maintenance efficiency of the charging pile 500 and reducing maintenance costs.

[0085] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
