Description

Gun line storage device and charging pile

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on February 27, 2024, with application number 202410214384.0 and application name “Gun Wire Storage Device and Charging Pile”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The embodiments of the present application relate to the technical field of charging equipment, and in particular to a gun line storage device and a charging pile. Background Art

[0003] With the rise of new energy vehicles, the application of charging piles is becoming increasingly widespread. Charging piles are used to provide charging services for new energy vehicles. Currently available charging piles usually include a charging cabinet and a charging gun. The charging gun is connected to the charging cabinet, and the charging cable of the charging gun passes through the side wall of the charging cabinet. A fixed structure is generally provided at the passing position to avoid wear of the charging cable caused by the relative movement between the charging cable and the cabinet, thereby reducing the life of the charging cable. In addition, a cavity for storing the charging gun is provided on the charging cabinet. When charging, the charging gun is pulled out of the cavity to charge the new energy vehicle. When not charging, the charging gun is plugged into the cavity to store the charging gun. However, the cavity on the current charging cabinet is an embedded cavity, that is, the cavity needs to occupy the space inside the charging cabinet, affecting the installation of components inside the charging cabinet. In addition, the functions of the various structures of the current charging piles are single, and the degree of integration is low. Summary of the Invention

[0004] The main technical problem solved by the embodiments of the present application is to provide a gun line storage device and a charging pile, which can effectively improve the integration level of the gun line storage device.

[0005] In order to solve the problems existing in the prior art, a technical solution adopted in an embodiment of the present application is: to provide a gun wire storage device, including: a gun plug seat, a charging cable, a spring assembly and a charging gun. The gun plug seat is arranged on the outer wall of the cabinet, and the gun plug seat is provided with a first receiving cavity and a second receiving cavity; the charging cable passes through the wire outlet of the cabinet, the first receiving cavity is connected to the wire outlet, the first end of the charging cable is located in the first receiving cavity, and the first end of the charging cable is connected and fixed to the gun plug seat; the spring assembly is connected to the gun plug seat, and the spring assembly is partially connected to the charging cable to support the charging cable; the charging gun is electrically connected to the second end of the charging cable, and at least a part of the charging gun can be plugged into the second receiving cavity. The gun wire storage device of the present application has at least the functions of protecting the charging cable, providing an installation position for the spring assembly, and providing a storage position for the charging gun, which can improve the degree of integration of the gun wire storage device.

[0006] In one embodiment, the back of the gun socket is in contact with the outer wall of the cabinet, and the first receiving cavity at least partially extends through the back of the gun socket, allowing the charging cable located within the first receiving cavity to connect to the interior of the cabinet. The first end of the charging cable is disposed within the first receiving cavity of the gun socket. This protects the charging cable as it exits the cabinet, significantly reducing the stress on the charging cable at the outlet and the probability of damage there. Furthermore, the first receiving cavity on the gun socket also provides space for the curved portion of the charging cable after exiting.

[0007] In one embodiment, a notch is provided at the top of the gun plug seat, which connects the first receiving chamber to the outside world. The charging cable includes a wire body, a protective layer, and a fixing sleeve. The protective layer is wrapped around the outer periphery of the wire body, and the fixing sleeve is disposed in the notch to connect and secure the protective layer to the gun plug seat. By providing a notch at the top of the gun plug seat, the charging cable can extend directly from the top of the gun plug seat, reducing the number of bends in the charging cable and lowering the difficulty of production. The fixing sleeve in the charging cable is disposed in the notch to securely connect the protective layer wrapped around the wire body to the gun plug seat, while also reducing wear on the protective layer and extending the service life of the charging cable.

[0008] In one embodiment, the second receiving cavity is located on the front of the charging gun holder, with the front and back sides of the holder facing each other. Compared to other locations, by having the second receiving cavity located on the front of the holder, the charging gun can be inserted into the second receiving cavity roughly horizontally. The user can directly observe the cavity opening of the second receiving cavity, making it easier for the user to align the charging gun with the cavity opening, greatly reducing the difficulty of plugging and unplugging the charging gun.

[0009] In one embodiment, a charging gun includes a connected gun body and a gun head, the second end of the charging cable is connected to the gun body, and the charging cable is electrically connected to the gun head. The gun body is used for holding by a user, and the gun head is used to be inserted into a second receiving cavity of a gun socket, or the gun head is used to be plugged into and connected to a device to be charged. When the charging gun is plugged into the gun socket, only the gun head is inserted into the second receiving cavity. Compared to accommodating the entire charging gun, the space of the second receiving cavity that only accommodates the gun head can be designed to be smaller, thereby reducing the overall volume of the gun socket.

[0010] In one embodiment, on a projection plane perpendicular to the direction of insertion between the charging gun and the second receiving chamber, the projection of the gun tip lies within the projection of the gun body; when the gun tip is inserted into the second receiving chamber, the gun body blocks the opening of the second receiving chamber. The projection of the gun tip lies within the projection of the gun body, meaning that the radial dimension of the gun tip is smaller than that of the gun body, forming a step at the connection between the gun body and the gun tip. When the gun tip is inserted into the second receiving chamber, the gun body cannot enter the second receiving chamber, and the gun body blocks the opening of the second receiving chamber. This significantly reduces the risk of external debris and dust entering the second receiving chamber and contaminating the gun tip, ensuring the cleanliness of the gun tip.

[0011] In one embodiment, the charging gun holder has opposing top and bottom portions, and the second receiving chamber is enclosed by a cavity wall and a cavity bottom. The cavity bottom of the second receiving chamber is offset relative to the cavity opening toward the bottom of the charging gun holder, and the angle between the cavity wall and the cavity bottom of the second receiving chamber is acute. By configuring the second receiving chamber to have an inclined structure, when the charging gun is inserted into the second receiving chamber, a fulcrum is formed at the cavity opening. Under the action of the gravity of the gun body and the charging cable, the gun tip tends to move upward, thereby tightly contacting the cavity wall of the second receiving chamber, further enhancing the secure connection between the charging gun and the charging gun holder.

[0012] In one embodiment, the charging gun holder has a first anti-slip feature, which is located on the inner wall of the second receiving cavity. The charging gun has a second anti-slip feature. When the charging gun is inserted into the second receiving cavity, the first anti-slip feature connects with the second anti-slip feature. The provision of the first and second anti-slip features further enhances the connection stability between the charging gun and the holder.

[0013] In one embodiment, a spring assembly is positioned at the top of the gun mount. The spring assembly includes a connecting component, a spring, and a cable-securing structure. The first end of the spring is connected to the gun mount via the connecting component, and the cable-securing structure is positioned at the second end of the spring and connected to the charging cable. Because the charging cable extends directly through a notch at the top of the gun mount, positioning the spring assembly supporting the charging cable directly at the top of the gun mount can reduce the extension offset of the charging cable, reduce the lateral pressure exerted by the gun mount on the charging cable at the notch, and extend the service life of the charging cable. Furthermore, compared to other locations on the gun mount, the spring assembly can be installed more quickly and conveniently at the top of the gun mount, improving assembly efficiency.

[0014] In one embodiment, the connecting component includes a mounting column and a fixing piece. The gun seat is provided with a mounting hole. Part of the mounting column is inserted into the mounting hole. The mounting column is provided with a threaded hole. The fixing piece is screwed to the threaded hole. The part of the mounting column protruding from the gun seat is connected and fixed to the first end of the spring.

[0015] In one embodiment, the spring assembly further includes a connecting tube, the first end of which is connected to the second end of the spring, and the second end of which is connected to the cable mounting structure. By adding the connecting tube between the spring and the cable mounting structure, the upward extension of the spring assembly can be further increased, thereby lifting the charging cable further. Furthermore, compared to installing an entire spring between the plug socket and the cable mounting structure, using the connecting tube to replace part of the spring length can reduce costs.

[0016] In one embodiment, the gun cable storage device further includes a cable clamp having a first end and a second end. The first end of the cable clamp is connected to the cable fixing structure, and at least a portion between the first end and the second end of the cable clamp is curved, and the charging cable is partially inserted into the cable clamp. Disposing the at least partially curved cable clamp above the cable fixing structure can guide and support the charging cable, effectively reducing bending stress in the charging cable near the cable fixing structure.

[0017] In one embodiment, the cable clamp can rotate relative to the cable fixing structure, thereby adjusting the guiding direction of the cable clamp on the charging cable to adapt to different usage and installation environments.

[0018] In order to solve the above technical problems, a technical solution adopted in an embodiment of the present application is: providing a charging pile, including a cabinet, a power supply device and a gun wire storage device, the power supply device is arranged inside the cabinet; the cabinet is provided with a wire outlet, and the gun socket is arranged on the outer wall of the cabinet and covers the wire outlet; the charging cable is electrically connected to the power supply device, and the charging cable is connected to the gun socket after passing through the wire outlet.

[0019] The gun wire storage device of the embodiment of the present application includes a gun plug seat, a charging cable, a spring assembly and a charging gun. The gun plug seat is arranged on the outer wall of the cabinet, and the gun plug seat is provided with a first receiving cavity and a second receiving cavity; the charging cable passes through the cable outlet of the cabinet, the first receiving cavity is connected to the cable outlet, the first end of the charging cable is located in the first receiving cavity, and the first end of the charging cable is connected and fixed to the gun plug seat; the spring assembly is connected to the gun plug seat, and the spring assembly is partially connected to the charging cable to support the charging cable; the charging gun is electrically connected to the second end of the charging cable, and at least a part of the charging gun can be plugged into the second receiving cavity. The gun wire storage device of the present application has at least the functions of protecting the charging cable, providing an installation position for the spring assembly, and providing a storage position for the charging gun, which can improve the degree of integration of the gun wire storage device.

[0031] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0032] Please refer to Figures 1 to 4. An embodiment of the present application provides a gun wire storage device 100, which includes a gun plug seat 10, a charging cable 20, a charging gun 30 and a spring assembly 40. The gun plug seat 10 is arranged on the outer wall of the cabinet 200, and the gun plug seat 10 is provided with a first receiving cavity 11 and a second receiving cavity 12. The first receiving cavity 11 and the second receiving cavity 12 may be connected or not. The charging cable 20 is electrically connected to the internal components of the cabinet 200 and passes through the wire outlet 201 of the cabinet 200. The gun plug seat 10 is arranged at the wire outlet 201 so that the first receiving cavity 11 is connected to the wire outlet 201, the first end 21 of the charging cable 20 is located in the first receiving cavity 11, and the first end 21 of the charging cable 20 is connected and fixed to the gun plug seat 10. This can protect the charging cable 20 passing through the cabinet 200 , greatly reduce the force on the charging cable 20 at the outlet 201 , and reduce the probability of the charging cable 20 being damaged at the outlet 201 .

[0033] The spring assembly 40 is connected to the gun socket 10 and partially connected to the charging cable 20, thereby enabling the spring assembly 40 to support the charging cable 20. The gun socket 10 provides a mounting location for the spring assembly 40. While the spring assembly 40 supports the charging cable 20, it does not need to be installed elsewhere in the cabinet 200, which takes up space and improves the integrity and aesthetics of the gun cable storage device 100.

[0034] The charging gun 30 is electrically connected to the second end 22 of the charging cable 20. The charging gun 30 is used to connect to an external device to be charged, such as a car, to provide power to the external device. When not charging, at least a portion of the charging gun 30 can be accommodated in the second receiving cavity 12 of the gun socket 10. Alternatively, when charging, at least a portion of the charging gun 30 can be removed from the second receiving cavity 12 of the gun socket 10. The first end 21 and second end 22 of the charging cable 20 are arranged opposite each other.

[0035] The charging cable holder 10 has a second receiving cavity 12 for accommodating at least part of the charging cable 30, providing a storage location for the charging cable 30. This effectively solves the problem of the prior art requiring an additional storage structure on the cabinet 200 to accommodate the charging cable 30, thereby occupying space within the cabinet 200. The cable storage device 100 of the present application at least functions to protect the charging cable 20, provide a mounting location for the spring assembly 40, and provide a storage location for the charging cable 30, effectively improving the level of integration of the cable storage device 100.

[0036] Regarding the aforementioned gun holder 10, as shown in Figure 4 , the gun holder 10 has a front face 10a and a back face 10b disposed opposite each other. The back face 10b of the gun holder 10 is attached to the outer wall of the cabinet 200. At least a portion of the first receiving cavity 11 of the gun holder 10 extends through the back face 10b, forming an opening at one end of the first receiving cavity 11 facing the back face 10b. This allows the charging cable 20, located within the first receiving cavity 11, to pass through the first receiving cavity 11 and into the interior of the cabinet 200 to establish an electrical connection.

[0037] The portion of the charging cable 20 extending from the cabinet 200 is generally perpendicular to the surface of the cabinet 200, such as the left-right direction in FIG5 . It bends from being perpendicular to the surface of the cabinet 200 to extending in a direction roughly parallel to the spring assembly 40, such as the up-down direction in FIG5 . This causes the charging cable 20 to have a large curvature bend, and the bent portion of the charging cable 20 is relatively fragile. Referring to FIG2 and FIG4 , the gun socket 10 has a first receiving cavity 11, and the bent portion of the charging cable 20 is accommodated in the first receiving cavity 11. The gun socket 10 protects the bent portion of the charging cable 20, effectively reducing the wear of the charging cable 20 caused by friction between the charging cable 20 and the cabinet 200 at the outlet 201, so that the areas of the charging cable 20 that are more easily damaged are protected by the gun socket 10, thereby extending the overall service life of the charging cable 20.

[0038] Continuing with Figures 3 and 7 , the charging gun holder 10 is provided with a second receiving chamber 12. The second receiving chamber 12 comprises a chamber opening 121, chamber walls 122, and a chamber bottom 123. The chamber walls 122 and chamber bottom 123 enclose the second receiving chamber 12. The chamber opening 121 and chamber bottom 123 are disposed opposite each other. The chamber opening 121 is used to allow the charging gun 30 to enter or be withdrawn from the second receiving chamber 12. It is worth noting that in some embodiments, the second receiving chamber 12 is used to partially accommodate the charging gun 30, i.e., the portion of the charging gun 30 is located outside the second receiving chamber 12. In other embodiments, the space in the second receiving chamber 12 is larger than the volume of the charging gun 30, so that the charging gun 30 can be fully accommodated within the second receiving chamber 12.

[0039] In some embodiments, the second receiving cavity 12 can be located on at least one of the front surface 10a, side surface, top surface, or bottom surface of the charging gun holder 10. The second receiving cavity 12 only needs to be able to accommodate at least a portion of the charging gun 30. Referring to Figure 3, in one embodiment, when the opening 121 of the second receiving cavity 12 is located on the front surface 10a of the charging gun holder 10, the charging gun 30 can be inserted into the second receiving cavity 12 generally horizontally. The user can directly observe the opening 121 of the second receiving cavity 12, making it easier for the user to align the charging gun 30 with the opening 121, greatly reducing the difficulty of inserting and removing the charging gun 30.

[0040] Continuing with Figure 3 , the gun socket 10 has opposing top and bottom portions 14 and 15 . When the gun cable storage device 100 is properly installed, the bottom portion 15 is closer to the ground than the top portion 14 . In some embodiments, the charging cable 20 can be routed through any of the top 14 , bottom 15 , or side portions 16 of the gun socket 10 . To ensure user convenience when using the charging gun 30 , the gun socket 10 is typically positioned lower in the cabinet 200 . Because the charging cable 20 is relatively long, raising it above the ground to maintain a certain distance from the ground can prevent wear and tear on the charging cable 20 caused by direct contact with the ground. In one embodiment, referring to Figures 3 and 4 , the top 14 of the gun socket 10 has a notch 13 , which connects the first receiving chamber 11 to the outside world. After exiting the notch 13 , the charging cable 20 at least partially extends along the bottom 15 toward the top 14 , meaning that the charging cable 20 partially extends upward.

[0041] In some embodiments, referring to Figures 2 and 4 , the charging cable 20 includes a cable 23, a protective layer 24, and a fixing sleeve 25. The protective layer 24 wraps around the outer periphery of the cable 23 to protect and insulate it. The fixing sleeve 25 is disposed around the outer periphery of the protective layer 24 and positioned within the notch 13 of the gun holder 10 to securely connect the protective layer 24 to the gun holder 10. The fixing sleeve 25 seals the protective layer 24 to the cable 23 within it and prevents the protective layer 24 from being damaged by friction at the notch 13 of the gun holder 10, thereby increasing the service life of the charging cable 20. It is worth noting that the cable 23 may include a conductive cable threaded within the protective layer 24 to provide power for the charging cable 20. In some embodiments, in addition to the conductive cable, the cable 23 may also include a liquid cooling tube. A liquid cooling medium is introduced into the cooling tube to promptly dissipate heat generated by the conductive cable when energized, thereby minimizing the temperature of the conductive cable and reducing the impact on current transmission.

[0042] In a partial embodiment of the second receiving cavity 12 housing a charging gun 30, see Figure 3 . The charging gun 30 includes a connected gun body 31 and a gun head 32. The second end 22 of the charging cable 20 is connected to the gun body 31, and the charging cable 20 is electrically connected to the gun head 32. The gun head 32 can be inserted into the second receiving cavity 12, while the gun body 31 is located outside the gun socket 10. In some examples, the shape of the second receiving cavity 12 can be configured to be substantially the same as that of the gun head 32, and the connection between the gun head 32 and the second receiving cavity 12 can be achieved through a clearance fit or transition fit. This can increase the secure connection between the charging gun 30 and the gun socket 10 and prevent the charging gun 30 from falling off the gun socket 10.

[0043] The charging gun 30 is inserted into the second receiving cavity 12 along the insertion direction. On a projection plane perpendicular to the insertion direction, the projection of the gun tip 32 lies within the projection of the gun body 31, meaning the cross-sectional area of ​​the gun tip 32 is smaller than that of the gun body 31. Once the gun tip 32 is inserted into the second receiving cavity 12, the gun body 31 shields the cavity opening 121 of the second receiving cavity 12, thereby protecting the gun tip 32 within the second receiving cavity 12 and preventing dust and other contamination that could affect charging performance.

[0044] In a partial embodiment of the second receiving chamber 12 housing the charging gun 30, see Figures 5 and 8 . The gun holder 10 has opposing tops 14 and bottoms 15. The bottom 123 of the second receiving chamber 12 is offset relative to the opening 121 toward the bottom 15 of the gun holder 10, resulting in an acute angle between the wall 122 and the bottom 123 of the second receiving chamber 12. When the charging gun 30 is tilted and inserted into the second receiving chamber 12, the opening 121 of the second receiving chamber 12 forms a fulcrum. Under the weight of the gun body 31 and the charging cable 20, the gun tip 32 moves upward and abuts against the upper wall 122 of the second receiving chamber 12, preventing the gun tip 32 from falling out of the second receiving chamber 12. Since the bottom 123 of the second receiving chamber 12 is inclined toward the bottom 15 of the gun holder 10, the gravity of the charging gun 30 is supported by the chamber wall 122 and the chamber bottom 123 respectively. Under the action of gravity, the charging gun 30 is guided to move toward the chamber bottom 123, and the chamber bottom 123 stops this movement, so that the gun head 32 of the charging gun 30 is stably accommodated in the second receiving chamber 12, and the charging gun 30 is not easily detached from the second receiving chamber 12.

[0045] In some embodiments, as shown in Figure 3, the charging gun holder 10 is provided with a first anti-detachment feature 17, which is disposed on the inner wall of the second receiving cavity 12. The charging gun 30 is provided with a second anti-detachment feature 33. When the charging gun 30 is inserted into the second receiving cavity 12, the second anti-detachment feature 33 connects with the first anti-detachment feature 17, thereby preventing the charging gun 30 from falling out of the second receiving cavity 12 and effectively improving the connection stability between the charging gun 30 and the charging gun holder 10. It is worth noting that when the charging gun 30 is charging an external device to be charged, such as a car, the second anti-detachment feature 33 on the charging gun 30 can also connect with the anti-detachment structure on the external device to be charged, thereby securing the charging gun 30 relative to the device to be charged. In one embodiment, the first anti-detachment feature 17 is a buckle, and the second anti-detachment feature 33 is a slot. Alternatively, the first anti-detachment feature 17 is a slot, and the second anti-detachment feature 33 is a buckle.

[0046] Regarding the aforementioned spring assembly 40, please refer to Figures 2 and 5 . The spring assembly 40 is connected to the gun mount 10 and is also connected to a portion of the charging cable 20, thereby supporting the charging cable 20 and pulling it away from the ground. In one embodiment, the spring assembly 40 can be located on the top 14 or side 16 of the gun mount 10, as long as the spring assembly 40 can support the portion of the charging cable 20 upward.

[0047] As an example, the spring assembly 40 is disposed at the top 14 of the gun plug seat 10, and the partial extension direction of the charging cable 20 is the same as the extension direction of the spring assembly 40. By arranging the spring assembly 40 at the top 14 of the gun plug seat 10, the charging cable 20 can be directly bent upward after extending from the cabinet 200 and connected to the spring assembly 40, thereby reducing the offset of the charging cable 20. In one embodiment, referring to FIG3 , the installation position of the spring assembly 40 at the top 14 of the gun plug seat 10 and the position of the notch 13 of the gun plug seat 10 are arranged sequentially from the back 10b of the gun plug seat 10 toward the front 10a thereof. This can further reduce the offset of the extended portion of the charging cable 20 relative to the notch 13, reduce the wear of the charging cable 20 by the sidewalls of the notch 13, and extend the service life of the charging cable 20.

[0048] In some embodiments, referring to FIG2 , the spring assembly 40 includes a connecting member 41, a spring 42, and a cable securing structure 43. The spring 42 has opposing first and second ends 421 and 422. The first end 421 of the spring 42 is connected to the charging cable holder 10 via the connecting member 41. The cable securing structure 43 is disposed at the second end 422 of the spring 42 and is connected to the charging cable 20, so that the spring assembly 40 moves with the charging cable 20, and vice versa. When the spring 42 is in its initial position, it extends generally vertically and supports the charging cable 20 extending generally vertically upward from the charging cable holder 10. When subjected to an external force, the spring 42 elastically deforms and returns to its initial position upon removal of the external force. Generally, when the spring 42 is in its initial position, the charging cable 30 is positioned above the charging port of the device to be charged. The user needs to pull the charging cable 30 to align it with the charging port of the device to be charged. Specifically, when the user needs to use the charging gun 30 to charge, they drag the charging cable 20 to move. Since the charging cable 20 is fixedly connected to the cable fixing structure 43, the spring 42 is elastically deformed, and the spring assembly 40 moves with the charging cable 20. When the user completes charging and inserts the charging gun 30 into the second receiving cavity 12, the external force on the charging cable 20 is released. Under the action of the spring 42, the charging cable 20 follows the spring assembly 40 and returns to its initial state of upward extension. The spring 42 and the cable fixing structure 43 provide support for the charging cable 20.

[0049] The initial state of spring 42 refers to the state of spring 42 when it is only subjected to its own weight and the weight of the charging cable 20 and charging gun 30. At this time, spring 42 extends generally in the vertical direction. The external force acting on spring 42 refers to any force other than the weight of spring 42 and the pulling force from the weight of the charging cable 20 and charging gun 30, such as the user's pulling force.

[0050] In some embodiments, as shown in Figures 5 and 6 , the connecting component 41 includes a mounting post 411 and a fixing member 412. The gun mount 10 is provided with a mounting hole 18. The lower portion of the mounting post 411 is inserted into the mounting hole 18, while the upper portion of the mounting post 411 protrudes from the gun mount 10. The lower portion of the mounting post 411 is provided with a threaded hole. The fixing member 412 passes through the gun mount 10 and is screwed into the threaded hole, thereby securing the mounting post 411 to the gun mount 10. The portion of the mounting post 411 protruding from the gun mount 10 is connected and fixed to the first end of the spring 42, thereby securing the first end of the spring 42 relative to the gun mount 10, completing the installation of the spring 42.

[0051] In some embodiments, referring to FIG. 2 , a cable securing structure 43 is disposed at the second end 422 of the spring 42. The cable securing structure 43 includes a first portion 431 and a second portion 432. The first portion 431 and the second portion 432 are respectively configured to clamp onto a portion of the outer surface of the charging cable 20, thereby securing the charging cable 20 to the spring 42. It is worth noting that the first portion 431 and the second portion 432 can be directly fastened together or connected via fasteners such as screws.

[0052] In some embodiments, referring to FIG. 2 , the spring assembly 40 further includes a connecting tube 44 having opposing first and second ends 441 and 442. The first end 441 of the connecting tube 44 is connected to the second end 422 of the spring 42, while the second end 442 of the connecting tube 44 is connected to the cable securing structure 43. By adding the connecting tube 44 between the spring 42 and the cable securing structure 43, the upward extension of the spring assembly 40 can be further increased, thereby lifting the charging cable 20 further. Furthermore, compared to installing an entire spring 42 between the charging cable holder 10 and the cable securing structure 43, replacing a portion of the spring 42 with the connecting tube 44 can reduce costs. It is understood that in some embodiments, the spring assembly 40 can be configured without the connecting tube 44, with the spring 42 connecting the cable securing structure 43 and the charging cable holder 10.

[0053] In some embodiments, as shown in FIG2 , the cable storage device 100 further includes a cable clamp 50. The cable clamp 50 is used to clamp a portion of the charging cable 20 to guide the charging cable 20 and prevent it from breaking. As an example, the cable clamp 50 has a first end 51 and a second end 52. The first end 51 of the cable clamp 50 is connected to the cable securing structure 43. At least a portion between the first end 51 and the second end 52 of the cable clamp 50 is curved, and the charging cable 20 is threaded through the cable clamp 50. After passing through the cable securing structure 43, the charging cable 20 sags under its own weight. This means that the portion of the charging cable 20 near the cable securing structure 43 experiences greater bending stress than the rest of the charging cable 20, making this portion more susceptible to damage and failure. Disposing the cable clamp 50, which is at least partially curved, above the cable securing structure 43 can guide and support the charging cable 20, effectively reducing the bending stress in the portion of the charging cable 20 near the cable securing structure 43.

[0054] In some embodiments, the wire clamp 50 can be rotated relative to the cable fixing structure 43 to adjust the guiding direction of the wire clamp 50 on the charging cable 20 to adapt to different usage and installation environments. In some examples, the wire clamp 50 can be assembled with the cable fixing structure 43 at different deflection angles so that the second end of the wire clamp 50 is closer to the cabinet 200 or further away from the cabinet 200. After assembly, the wire clamp 50 is fixed relative to the cable fixing structure 43. In other examples, after assembly, the wire clamp 50 and the cable fixing structure 43 are still able to rotate relative to each other, so that during use, the wire clamp 50 can adjust the deflection angle between the wire clamp 50 and the cable fixing structure 43 at any time.

[0055] In some embodiments, the cable storage device 100 further includes an indicator light assembly, which is disposed on the charging gun socket 10 and is used to display the operating status of the charging gun 30. In other embodiments, the surface of the charging gun socket 10 is further provided with a number for the charging gun 30 to facilitate labeling and information display of the charging gun 30.
