[0032] The technical solution of this application will be described in detail below with reference to the embodiments and accompanying drawings.

[0034] with reference to Figures 1 to 7 as shown, some embodiments of the present application provide a charging pile gun cable management device 100, comprising a mounting base 110, the mounting base 110 includes a top plate 111, a side plate 112 and a bottom plate 113, the top plate 111, the side plate 112 and the bottom plate 113 are connected in sequence so that the mounting base 110 is in a "C" shape with a groove.

[0035] In some embodiments of the present application, the bottom plate 113 is provided with a mounting hole 114, which is used for mounting the mounting base 110 on the charging pile body.

[0036] The main body of the mounting base 110 of the present application is only composed of three plates, the top plate 111, the side plate 112 and the bottom plate 113, and the structure is extremely simple.

[0037] In some embodiments of the present application, the mounting holes provided on the top plate 111 and the bottom plate 113 correspond to each other. In some embodiments of the present application, when viewed from a direction perpendicular to the top plate 111 or the bottom plate 113, the mounting holes are distributed on both sides of the side plate 112. That is to say, the mounting base 110 can be used by being vertically flipped, and is universal for leftward swing arms and rightward swing arms.

[0038] with further reference to Figure 1 and Figure 5 as shown, the charging pile gun cable management device 100 further comprises a rotating shaft 130, at least one end of the rotating shaft 130 is fixedly connected to the mounting base.

[0039] In some embodiments of the present application, the top plate 111 and the bottom plate 113 are perpendicular to the rotating shaft 130.

[0040] with further reference to Figures 1 to 7As shown, the charging pile gun line management device 100 further includes a first swing arm 170, which includes a first joint 120. The first swing arm 170 is configured to rotate about the pivot 130 via the first joint 120. Specifically, the swing arm 170 drives the first joint 120 to rotate when it swings. The swing of the first swing arm 170 is also limited by the side plate 112. A buffer pad 115 may be provided on the side plate 112 to provide elastic buffering when the first swing arm 170 swings to its limit position. The first joint 120 is disposed in the groove of the mounting base 110 and does not contact the top plate 111, side plate 112, and bottom plate 113. The first joint 120 needs to rotate as a joint, and to reduce friction, the first joint 120 does not contact the top plate 111, side plate 112, and bottom plate 113. The first joint 120 has a cylindrical structure with an internal cavity to accommodate various internal parts.

[0041] Continue to refer to Figure 1 and Figure 5 As shown, in some embodiments of this application, sealing cover plates 121 are provided at both the top and bottom of the first joint 120, and the sealing cover plates 121 are fixedly connected to the first joint 120 by sealing connectors 122 (e.g., screws). It should be noted that some particularly common parts and structures have been omitted in the specification and drawings of this application, such as gaskets commonly used in connectors and connecting holes adapted to connectors. Those skilled in the art should be able to understand the configuration of these common parts based on common knowledge.

[0042] Continue to refer to Figures 1 to 7 As shown, in some embodiments of this application, the charging pile gun line management device 100 further includes: an upper fixing cover 140, which is fixedly connected to the top plate 111 via an upper connector 141 (e.g., a screw), and the rotating shaft 130 is fixedly connected to the upper fixing cover 140 and thus to the top plate 111. For aesthetic and simple appearance, and to reduce unnecessary protrusions, the top plate 111 may be provided with through holes and grooves matching the upper fixing cover 140, with the upper fixing cover 140 fitting precisely into these through holes and grooves, ensuring that the surface of the top plate 111 is approximately flat.

[0043] Continue to refer to Figure 1 As shown, in some embodiments of this application, the upper fixing cover 140 has an upper mounting hole, and the inner wall of the upper mounting hole and the outer wall of the rotating shaft 130 are respectively provided with mating threaded structures. The rotating shaft 130 and the upper fixing cover 140 are fixedly connected by threads. Specifically, refer to Figure 1As shown, the upper fixing cover 140 has a downward protrusion, which is cylindrical and has mounting holes. It should be noted that this application only demonstrates the fixed connection of the rotating shaft 130 and the top plate 111 via the upper fixing cover 140. The rotating shaft 130 and the top plate 111 can also be fixedly connected by any other suitable method.

[0044] Continue to refer to Figure 1 and Figure 5 As shown in some embodiments of this application, the charging pile gun management device 100 further includes: a lower fixing cover 150, which is fixedly positioned on the base plate 113 by a bottom fixing plate 151 and a lower connecting member 152. The rotating shaft 130 is fixedly connected to the lower fixing cover 150 and thus to the base plate 113. The base plate 113 is provided with a through hole adapted to the lower fixing cover 150, and the lower fixing cover 150 is embedded in the through hole.

[0045] Continue to refer to Figure 1 As shown, in some embodiments of this application, the lower fixing cover 150 has a lower mounting hole, and the inner wall of the lower mounting hole and the outer wall of the rotating shaft 130 are respectively provided with mating threaded structures. The rotating shaft 130 and the lower fixing cover 150 are fixedly connected by threads. The lower fixing cover 150 is structurally different from the upper fixing cover 140. The lower fixing cover 150 is a hollow cylinder. The upper fixing cover 140 is a connecting body of a flat plate and a hollow cylinder.

[0046] Continue to refer to Figure 1 and Figure 5As shown in some embodiments of this application, the charging pile gun management device 100 further includes a restoring torque generating device 160, which generates a restoring torque to cause the first swing arm 170 to tend to remain in its initial position relative to the mounting base 110 and the rotating shaft 130. The restoring torque generating device 160 is disposed in the first joint 120, connecting the first joint 120 and the rotating shaft 130. The restoring torque generating device 160 includes a coil spring, the first joint 120 includes a coil spring receiving cavity, the coil spring is disposed in the coil spring receiving cavity, the inner ring of the coil spring is connected to the rotating shaft 130, and the outer ring of the coil spring is connected to the first joint 120. The end of the inner ring of the coil spring engages with a locking groove of the rotating shaft, and the end of the outer ring of the coil spring engages with a locking groove on the inner wall of the coil spring receiving cavity of the first joint. Specifically, the inner wall of the cavity of the first joint 120 is provided with a groove to limit and fix the outer ring of the coil spring; the rotating shaft 130 has a notch that fits against the inner ring of the coil spring, thus fixing the rotating shaft 130 to the inner ring of the coil spring. When the first joint 120 rotates, it causes the coil spring to tighten or loosen. The preload of the coil spring can be adjusted by rotating the rotating shaft 130 through the lower fixing cover 150 before the rotating shaft 130 is fully fixed, for example, before the upper fixing cover 140 is fully fixed.

[0047] In some embodiments of this application, when the first swing arm 170 swings in the first direction, it causes the first joint 120 to rotate, thereby tightening the coil spring; or when the restoring force of the coil spring drives the first joint 120 to rotate in the second direction, it causes the first swing arm 170 to swing in the second direction.

[0048] Continue to refer to Figure 1 and Figure 5 As shown, in some embodiments of this application, the two ends of the rotating shaft 130 are respectively provided with a first bearing 131 and a second bearing 132, and the first joint 120 rotates around the rotating shaft 130 based on the first bearing 131 and the second bearing 132.

[0049] refer to Figure 1As shown, the upper fixing cover 140 abuts against the top surface of the inner ring of the first bearing 131, and the sealing cover plate 121 abuts against the top surface of the outer ring of the first bearing 131. The upper fixing cover 140 and the sealing cover plate 121 together limit the top surface of the first bearing 131. The side wall of the rotating shaft 130 has a first stepped structure, which abuts against the bottom surface of the inner ring of the first bearing 131. The bottom surface of the outer ring of the first bearing 131 is supported by the first bearing support ring 133, and the side wall of the first bearing 131 is limited by the first bearing support ring 133. The top surface of the first bearing support ring 133 abuts against the sealing cover plate 121, and the bottom surface of the first bearing support ring 133 abuts against the restoring torque generating device 160, limiting the restoring torque generating device 160.

[0050] Continue to refer to Figure 1 As shown, the lower fixing cover 150 abuts against the bottom surface of the inner ring of the second bearing 132, and the sealing cover plate 121 abuts against the bottom surface of the outer ring of the second bearing 132. The lower fixing cover 150 and the sealing cover plate 121 together limit the bottom surface of the second bearing 132. The side wall of the rotating shaft 130 has a second stepped structure, which abuts against the top surface of the inner ring of the second bearing 132. The bottom surface of the outer ring of the second bearing 132 is supported by the second bearing support ring 134, and the side wall of the second bearing 132 is limited by the second bearing support ring 134. The bottom surface of the second bearing support ring 134 abuts against the sealing cover plate 121, and the top surface of the second bearing support ring 134 abuts against the restoring torque generating device 160, limiting the restoring torque generating device 160.

[0051] The charging station gun management device 100 operates as follows: When the charging gun is not in use, the restoring torque generating device 160 is set with an initial preload. Specifically, the first joint 120 and the first swing arm 170 are constrained by this initial preload at the initial position defined by the side plate 112. When the user uses the charging gun, the charging gun cable causes the first swing arm 170 to swing, thereby causing the first joint 120 to rotate and thus causing the restoring torque generating device 160 to tighten. After the charging gun is used, the restoring torque generating device 160 relaxes under the action of the retracting force, causing the first joint 120 and the first swing arm 170 to swing, thereby achieving the automatic reset of the first swing arm 170.

[0052] Most swing arms currently on the market lack a reset function, preventing the cable from retracting after being extended, leading to cable dragging and wear on the ground. The technical solution presented in this application achieves automatic reset of the swing arm and cable through the cooperation of a restoring torque generator and a rotating shaft, offering greater flexibility in space utilization and cable arrangement. Furthermore, the structure allows for pre-tensioning by rotating the shaft before use, enabling the reset force to be pre-adjusted for cables of different lengths and weights, ensuring the cable automatically returns to its starting point after use and guaranteeing orderly cable suspension on site.

[0053] In some embodiments of this application, the end of the first swing arm 170 is provided with a connector for connecting to the gun wire.

[0054] refer to Figure 5 As shown in some embodiments of this application, the charging pile gun line management device 100 further includes: a second swing arm 180, which is connected to the first swing arm 170 and configured to rotate around the first swing arm 170. One end of the second swing arm 180 is hinged to the first swing arm 170, and the other end of the second swing arm 180 is provided with a connector for connecting to the gun line.

[0055] In some embodiments of this application, the second swing arm 180 is connected to the first swing arm 170 via a second joint 190. In some embodiments of this application, the structure of the second joint 190 may be the same as or similar to that of the first joint 120, that is, the second joint 190 may also be provided with a corresponding rotating shaft and a restoring torque generating device, etc., to realize the automatic reset of the second swing arm 180.

[0056] It should be noted that this application only illustrates an embodiment of the technical solution of this application with a two-stage swing arm. However, those skilled in the art should understand that the technical solution of this application is not limited to this, and the swing arm of this application can have more stages.

[0057] In some embodiments of this application, the charging pile gun line management device further includes: a third swing arm, the third swing arm being connected to the second swing arm and configured such that one end of the third swing arm is hinged to the second swing arm, and the other end of the third swing arm is provided with a connector for connecting to the gun line.

[0058] In some embodiments of this application, the charging pile gun cable management device further includes: a balancer mounting compartment, integrally connected to the first swing arm and extending to one side of the first swing arm; a coil spring balancer, installed in the balancer mounting compartment, for the cable connecting the charging gun cable passing through the first swing arm and wound around the coil spring balancer; and a mounting compartment cover, located on top of the balancer mounting compartment, to close the balancer mounting compartment. The cable-pulling mechanism (coil spring balancer) for connecting the cable is directly mounted on the swing arm, which further simplifies the structure, reduces the overall space occupied by the swing arm device, and achieves miniaturization of the mechanism.

[0059] Figure 8 This is a structural schematic diagram of a charging pile gun line management device according to other embodiments of this application.

[0060] refer to Figure 8 As shown, in some other embodiments of this application, the charging station cable management device 100 further includes a damper 143, installed on the first joint 120. The damper 143 is a unidirectional damper. When the first joint 120 rotates in the first direction (the direction of cable release), the damper 143 does not work. When the first joint 120 rotates in the second direction (the direction of cable retraction), the damper 143 works to provide damping to the first joint 120, slowing down the rotation speed of the first joint 120, thereby slowing down the cable retraction speed and preventing the charging station cable from moving too fast and hitting the charging station or nearby personnel. The damper 143 can be installed on the bottom or top surface of the first joint 120. This application uses the installation of the damper 143 on the top surface of the first joint 120 as an example. Specifically, the upper fixed cover 140 has a cylindrical shaft portion, and the damper 143 is sleeved on the shaft portion between the first joint 120 and the top plate 111.

[0061] In the charging pile gun line management device of this application, the restoring torque generating device is built into the cavity of the swing arm joint, and the installation, limiting and protection functions are integrated by relying on the swing arm body. The layout is simple and compact, and the structural integration is greatly improved.

[0062] The charging pile gun line management device of this application has no external protruding structure, which greatly reduces the overall space occupied by the swing arm device, realizes the miniaturization of the mechanism, and can easily adapt to various new energy charging piles.

[0063] The charging pile gun line management device of this application reduces the types and quantities of parts, which effectively reduces material procurement, mold making, warehousing and management costs, shortens assembly time, significantly reduces labor production costs, and greatly improves the economy of mass production.

[0064] The technical solution of this application designs a swing arm device with a built-in coaxial restoring torque generating device, which has the following features: the restoring torque generating device used to provide the restoring force of the swing arm is coaxially housed and installed in the hollow cavity inside the swing arm joint, so that the restoring torque generating device is completely hidden inside the swing arm, realizing the integrated layout of the restoring torque generating device and the swing arm, eliminating all external redundant structures from the root; simplifying the overall device configuration, and achieving the lightweight and miniaturization upgrade of the swing arm device without reducing the structural strength and restoring performance.

[0065] The charging pile gun management device provided in this application embodiment integrates the restoring torque generating device inside the swing arm, simplifying the overall device configuration and achieving lightweight and miniaturized upgrades of the swing arm device without reducing structural strength and reset performance.
