Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, and in particular to a charging pile cable anti-drag device. Background Technology

[0002] A charging gun is a connector used to charge electric vehicles, acting as a bridge between the charging station and the vehicle. Depending on the charging type, charging guns can be divided into two types: DC charging guns: also known as fast charging guns, they feature rapid charging, capable of fully charging the battery in approximately 30 minutes. DC charging guns are typically used for long-distance travel or emergency charging situations. Due to their fast charging characteristics, DC charging guns usually require a larger power supply and are typically located at dedicated charging stations. AC charging guns: also known as slow charging guns, they charge relatively slowly, typically taking several hours or even longer to fully charge the battery. AC charging guns are less expensive, suitable for charging needs in homes or commercial settings, and can be charged using ordinary household power.

[0003] Because charging guns are too heavy, many electric vehicle owners simply toss them on the ground after charging, leading to issues such as broken handles, detached rubber casings, and cables being run over by car wheels. These problems affect user electrical safety, cable lifespan, and charging convenience.

[0004] To address the aforementioned issues, some charging piles are equipped with spring balancers to hold the charging pile cable in place. However, these balancers typically only limit the cable at one point, resulting in the cable forming two upward-pulling arcs in the middle during use, requiring a relatively long cable length to be reserved. Utility Model Content

[0005] This utility model provides a charging pile cable anti-drag device, which aims to solve at least one of the above-mentioned technical problems.

[0006] This utility model provides the following technical solution: A charging pile cable anti-drag device includes a spring balancer installed on the upper part of the same side, a folding rod that can be rotatably installed below the spring balancer, the end of the pull rope of the spring balancer is connected to the folding shaft of the folding rod, and a plurality of limiting sleeves are fixed on the folding rod, through which the charging pile cable passes in sequence.

[0007] Optionally, the folding rod includes a first support rod and a second support rod. The first support rod is rotatably connected to the side of the charging pile, and the second support rod is rotatably connected to the first support rod. A folding assembly is installed at the connection between the first support rod and the second support rod. The folding assembly is used to control the folding angle between the first support rod and the second support rod.

[0008] Optionally, the folding assembly includes a hinge seat installed at the end of the first support rod, and a first connecting rod that cooperates with the hinge seat is fixed at the beginning of the second support rod. One end of the first connecting rod is hinged to the hinge seat, and the other end is rotatably connected to the beginning of the second support rod. A second connecting rod is also hinged to the hinge seat. One end of the second connecting rod is connected to the hinge seat, and the other end of the second connecting rod is rotatably connected to the side of the charging pile, forming a four-bar linkage, so that the folding rod can be folded along a predetermined trajectory when dragged by force.

[0009] Optionally, the hinge seat is a triangular structure with hinge holes at its three vertices for connecting the first support rod, the first connecting rod, and the second connecting rod.

[0010] Optionally, the limiting sleeve includes a sleeve with an annular groove on its outer wall. A clamp is embedded in the annular groove, and an mounting plate is fixed between the two ends of the clamp. The mounting plate is fixedly connected to the folding rod.

[0011] Optionally, the through hole of the sleeve is oriented along the length of the folding rod.

[0012] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0013] Compared to using only a spring balancer to pull the cable, this method allows the cable to extend horizontally with multiple limiting points. The structural design, combining a folding rod with the spring balancer, effectively increases the cable's extension stroke. Within the same range, this invention requires a shorter cable length, reducing cable usage costs and minimizing the risk of tangling. It also improves the stability and lifespan of cable retraction and extension. Furthermore, the shorter cable length reduces line losses during power transmission, further enhancing charging efficiency. When the external force is removed, the spring balancer automatically retracts the pull rope, causing the folding rod to return to its original trajectory. The limiting sleeve guides the cable to retract synchronously, preventing tangling.

[0014] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more obvious and understandable, specific embodiments of this utility model are given below.

[0022] To better understand the purpose, function, and specific design of this utility model, the following detailed description is provided in conjunction with the accompanying drawings.

[0023] like Figures 1-5 As shown, this application provides a charging pile cable anti-drag device, including a spring balancer 1 installed on the upper part of the same side, and a folding rod that can be rotatably installed below the spring balancer 1. The end of the pull rope 2 of the spring balancer 1 is connected to the folding shaft of the folding rod. Multiple limiting sleeves 5 are fixed on the folding rod, and the charging pile cable passes through the limiting sleeves 5 in sequence.

[0024] The aforementioned spring balancer 1 provides a constant tension to balance the weight of the folding rod and the cable. When the cable is pulled by an external force, the spring balancer 1 releases through the pull rope 2, cooperating with the folding rod to unfold from a vertical folded state to a horizontal state along the trajectory set by the four-bar linkage. The charging pile cable then extends smoothly. By limiting the charging pile cable at multiple points, the cable can gradually lay flat as the folding rod unfolds. Compared to using only the spring balancer 1 to pull the cable, the cable can extend horizontally under multiple limiting points. Through the structural design of the folding rod and the spring balancer 1, the extension stroke of the cable can be effectively increased. Within the same range, the cable length required by this invention is shorter, reducing the cable usage cost and reducing the risk of tangling. At the same time, it improves the stability and service life of the cable retraction and extension. Moreover, after the cable is shortened, the line loss during power transmission is also reduced, further improving charging efficiency. When the external force is removed, the spring balancer 1 automatically retracts the pull rope 2, driving the folding rod to return to its original trajectory. The limiting sleeve 5 guides the cable to retract synchronously, avoiding tangling.

[0025] The aforementioned limiting sleeve 5 is used to constrain the charging pile cable at multiple points to prevent it from twisting or shifting during the extension and retraction process, and to ensure that the cable extends synchronously along the unfolding direction of the folding rod.

[0026] Furthermore, the self-locking and self-stopping function of the spring balancer 1 and the pull rope 2 is an inherent function of the spring balancer 1.

[0027] In some embodiments, the folding rod includes a first support rod 4 and a second support rod 9. The first end of the first support rod 4 is rotatably connected to the side of the charging pile, and the end of the first support rod 4 is rotatably connected to the first end of the second support rod 9. A folding assembly is installed at the connection between the first support rod 4 and the second support rod 9. The folding assembly is used to control the folding angle between the first support rod 4 and the second support rod 9.

[0028] The charging pile is equipped with a fixing plate 6 on its side. A rotating shaft perpendicular to the fixing plate 6 is fixed on the fixing plate 6. The first end of the first support rod 4 is sleeved on the rotating shaft and rotatably connected to it. The end of the first support rod 4 has an ear seat 10. The ear seat 10 is hinged to the ear seat 10 at the beginning of the second support rod 9 by a pin, so that the first support rod 4 can rotate around the rotating shaft and the second support rod 9 can rotate around the pin at the end of the first support rod 4. A folding component is installed at the connection between the first support rod 4 and the second support rod 9, so as to realize the stable folding of the first support rod 4 and the second support rod 9.

[0029] Furthermore, by setting a folding component to control the position change of the end of the first support rod 4, the second support rod 9 is driven to adjust its posture synchronously. Specifically, when the first support rod 4 rotates from a vertical state to a horizontal state, the folding component guides the second support rod 9 to unfold at the same angular velocity, ensuring that the two supports rods always maintain coplanar movement and avoiding damage to the cable due to torsional force.

[0030] The folding assembly includes a meshing gear mechanism or a linkage structure to ensure that the angle changes of the first support rod 4 and the second support rod 9 are coordinated during movement, thereby achieving synchronous unfolding and folding. When the spring balancer 1 releases its tension, the folding assembly forces the two support rods to remain coplanar through mechanical transmission, effectively preventing torsional stress from occurring in the cable during dynamic extension.

[0031] In some embodiments, the folding assembly includes a hinge seat 7 installed at the end of the first support rod 4, and a first connecting rod 8 that cooperates with the hinge seat 7 is fixed at the beginning of the second support rod 9. One end of the first connecting rod 8 is hinged to the hinge seat 7, and the other end is rotatably connected to the beginning of the second support rod 9. A second connecting rod 3 is also hinged to the hinge seat 7. One end of the second connecting rod 3 is connected to the hinge seat 7, and the other end of the second connecting rod 3 is rotatably connected to the side of the charging pile, forming a four-bar linkage mechanism, so that the folding rod can be folded along a predetermined trajectory when dragged by force.

[0032] The first support rod 4, the first connecting rod 8, the hinge seat 7, and the side of the charging pile form a four-bar linkage mechanism, so that when the first support rod 4 rotates from the vertical to the horizontal direction, the second connecting rod 3 swings around its connection point with the side of the charging pile. During the swing, the hinge seat 7 rotates around the connection point between the hinge seat 7 and the first support rod 4, thereby driving the first connecting rod 8 to drive the second support rod 9 to unfold synchronously.

[0033] In some embodiments, the hinge seat 7 is a triangular structure with hinge holes at its three vertices for connecting the first support rod 4, the first connecting rod 8, and the second connecting rod 3.

[0034] When the first support rod 4 is in a vertical state, the second support rod 9 is tightly attached to the first support rod 4 under the constraint of the folding assembly, and the whole is in a folded state. At this time, the hinge seat 7 of the above-mentioned triangular structure is in a roughly horizontal state with the hinge point of the first connecting rod 8 and the second connecting rod 3. The first connecting rod 8 and the second connecting rod 3 are in a vertical state. When the first support rod 4 rotates in the horizontal direction, the second connecting rod 3 drives the hinge seat 7 to rotate around its connection point with the first support rod 4 towards the charging pile. At this time, the rotation of the hinge seat 7 drives the first connecting rod 8 to pull the second support rod 9 to unfold from the vertical to the horizontal direction around its connection point with the first connecting rod 8 until the second support rod 9 is fully extended and collinear with the first support rod 4.

[0035] Furthermore, the hinge seat 7 and the first connecting rod 8 are symmetrically installed on both sides of the first support rod 4 and the second support rod 9 to enhance structural stability and balance the force distribution.

[0036] In some embodiments, the limiting sleeve 5 includes a sleeve 502, the outer wall of the sleeve 502 has an annular groove, a clamp 503 is embedded in the annular groove, an installation plate is fixed between the two ends of the clamp 503, and the installation plate is fixedly connected to the folding rod.

[0037] The aforementioned limiting sleeve 5 is located on the side or bottom of the first support rod 4 and the second support rod 9, and is used to limit the horizontal displacement of the cable during the extension and retraction process. A through hole 501 adapted to the outer diameter of the cable is provided at the center of the sleeve 502, so that the cable can pass through. The outer middle of the sleeve 502 has an annular groove coaxial with the sleeve 502. The clamp 503 is fixed to the outer wall of the sleeve 502 through the annular groove. The mounting plate is connected to the folding rod to realize the overall fixation of the limiting sleeve 5. When the cable is unfolded or retracted with the folding assembly, the limiting sleeve 5 restricts its lateral displacement, ensuring that the cable can be smoothly retracted or unfolded in the vertical direction.

[0038] In some embodiments, the through hole of the sleeve 502 is oriented along the length of the folding rod.

[0039] The axis of the through hole of sleeve 502 is consistent with the extension and retraction direction of the folding rod, ensuring that the cable does not move laterally during movement, but only retracts or unfolds in the vertical plane.

[0040] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. In the absence of conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
