Both the first end and the third movable arm are provided with holes, which are inserted into the second lever arm or the fourth lever arm.
[0022] In some embodiments, the second movable arm includes multiple sub-sections connected end to end in sequence, with each pair of adjacent sub-sections being rotatably connected.
[0023] In some embodiments, the cable management device further includes a third elastic element that connects two adjacent sub-sections;
[0024] When the third elastic member is in its natural state, the sub-parts at each level fold together; when the sub-parts at multiple levels are in their unfolded state, the third elastic member undergoes elastic deformation.
[0025] In some embodiments, the cable management device further includes a rope having a first rope end and a second rope end disposed opposite to each other, the first rope end being connected to the third movable arm and the second rope end being connected to the clamping member.
[0026] In some embodiments, the third movable arm includes a body portion and a receiving portion, the receiving portion being disposed at one end of the body portion, the other end of the body portion being rotatably connected to the second end, and the receiving portion having a first opening communicating with its interior;
[0027] The cable management device further includes a limiting member disposed within the receiving portion. The limiting member includes a rod and a limiting portion.

[0036] The cable management device of this application embodiment can install the first movable arm on the charging pile and keep the first movable arm at a certain height. Then, the cable is clamped by the clamping member and the cable is pulled off the ground. At the same time, when the cable is pulled by the charging gun, the third movable arm and the second movable arm will unfold accordingly to cooperate with the movement of the cable and keep the cable off the ground, reducing the possibility of the cable dragging and friction, and playing a protective role for the cable. When the charging gun is returned to its original position after charging is completed, the cable moves back. At this time, under the elastic force of the first elastic member and the second elastic member, the third movable arm and the second movable arm rotate and fold back together, which is convenient and flexible.

Detailed Implementation
[0050] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0051] In the description of this application, it should be understood that the terms "height," "thickness," "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In the description of this application, "a plurality of" means two or more, and "at least one" can mean one, two, or more, unless otherwise explicitly specified. In the description of this application, "parallel" means completely parallel or nearly completely parallel; for example, parallelism is considered to be within a 10° range of complete parallelism.
[0052] It should also be noted that in the accompanying drawings of the embodiments of this application, the arrow marked with X represents the first direction X, and the arrow marked with Y represents the second direction Y. The introduction of the first direction X and the second direction Y is to more clearly illustrate the structure and relative positional relationship of each component in the cable management device. In practical applications, the first direction X and the second direction Y may change depending on the placement of the cable management device.
[0053] Referring to Figures 1, 2, and 3, the cable management device of this embodiment includes a first movable arm 1, a second movable arm 2, a third movable arm 3, a first elastic member 4, a second elastic member 5, and a clamping member 6. The first movable arm 1 is used to install on a charging pile or a wall near the charging pile. The first movable arm 1 has a first direction X and a second direction Y. The first direction X is the thickness direction of the first movable arm 1, and the second direction Y is the height direction of the first movable arm 1, and the second direction Y is parallel to the height direction of the charging pile.
[0054] The second movable arm 2 includes a first end 21 and a second end 22 disposed opposite to each other, that is, the first end 21 and the second end 22 are the two ends of the second movable arm 2 in the length direction. The first end 21 is rotatably connected to the first movable arm 1, and the rotatable connection point between the two is located at one end of the first movable arm 1 in the length direction. The first elastic member 4 is used to connect the first end 21 and the first movable arm 1. When the first elastic member 4 is in its natural state, the second movable arm 2 is folded over the first movable arm 1. At this time, the second movable arm 2 and the first movable arm 1 overlap or partially overlap in the first direction X, and the second end 22 corresponds to the other end of the first movable arm 1 in the length direction. It can be understood that the elastic member is in its natural state, that is, it is not deformed by external force.
[0055] The third movable arm 3 is rotatably connected to the second end 22. The second elastic element 5 is used to connect the second end 22 and the third movable arm 3. When the second elastic element 5 is in its natural state, the third movable arm 3 is folded over the second movable arm 2. At this time, the third movable arm 3 and the second movable arm 2 overlap or partially overlap in the first direction X.
[0056] A clamping member 6 is disposed on the third movable arm 3. The clamping member 6 is used to clamp the cable 102 to fix the cable 102 to the clamping member 6. When the cable 102 is subjected to tension, the third movable arm 3 and the second movable arm 2 unfold, and the first elastic member 4 and the second elastic member 5 undergo elastic deformation. The tension on the cable 102 is generated when the user pulls the cable 102 when using the charging gun 101. It can be understood that when the tension on the cable 102 is removed, the elastic force of the first elastic member 4 and the second elastic member 5 can drive the second movable arm 2 and the third movable arm 3 to rotate and fold.
[0057] The axes of the rotational connection points between the first end 21 and the first movable arm 1, and the second end 22 and the third movable arm 3, are both parallel to the second direction Y. On one hand, the clamping member 6 pulls the cable 102 off the ground; on the other hand, the unfolding and folding of the second movable arm 2 and the third movable arm 3 coordinate with the movement of the cable 102, ensuring the cable 102's range of motion, reducing the possibility of the cable 102 dragging on the ground and causing friction, and helping to protect the cable 102 from safety hazards.
[0058] Referring to Figures 2 and 4, in some embodiments, the cable management device includes at least two reset elastic elements 106. Each reset elastic element 106 includes a helical portion 40, a first lever arm 41, and a second lever arm 42. The helical portion 40 is formed by spirally winding an elastic material and is cylindrical in shape. It has elasticity and flexibility, can withstand and store torsional force, and has the ability to elastically deform and recover. The helical portion 40 has an axis M, which is parallel to the second direction Y. The first lever arm 41 and the second lever arm 42 are respectively connected to the two ends of the helical portion 40 along the helical direction. The first lever arm 41 and the second lever arm 42 can be integrally formed with the helical portion 40.
[0059] Alternatively, the reset elastic element 106 includes at least two helical portions 40, a third lever arm 43, and two fourth lever arms 44. The helical portions 40 have an axis M, and the two helical portions 40 are arranged at intervals along the axis M. The third lever arms 43 are arc-shaped and are respectively connected to the two helical portions 40 at their close ends. Each helical portion 40 at its end away from the third lever arm 43 is connected to a fourth lever arm 44. The two helical portions 40, the third lever arm 43, and the two fourth lever arms 44 can be integrally formed.
[0060] When the second movable arm 2 is folded over the first movable arm 1, the first elastic member 4 is in its natural state, and the angle between its first lever arm 41 and second lever arm 42 is 0. When the second movable arm 2 gradually rotates and unfolds, the first lever arm 41 and the second lever arm 42 are gradually opened by force, and the spiral part 40 is elastically twisted, thereby generating elastic deformation, and applying an elastic force to the second movable arm 2 in the opposite direction to the tension it receives.
[0061] Alternatively, when the second movable arm 2 is folded over the first movable arm 1, the first elastic element 4 is in its natural state, and the angle between its third force arm 43 and fourth force arm 44 is 0. When the second movable arm 2 gradually rotates and unfolds, the third force arm 43 and fourth force arm 44 are gradually opened by force, and drive the spiral part 40 to undergo elastic torsion, thereby generating elastic deformation and applying an elastic force to the second movable arm 2 in the opposite direction to the tension it receives.
[0062] The specific changes of the second elastic element 5 when the third movable arm 3 is in its natural state and its extended state are the same as those of the first elastic element 4, and will not be repeated here.
[0063] Referring to Figures 2 and 5 together, in some embodiments, when the first elastic member 4 includes a helical portion 40, a first lever arm 41, and a second lever arm 42, the helical portion 40 of the first elastic member 4 is disposed between the first end 21 and the first movable arm 1, the first lever arm 41 of the first elastic member 4 is connected to the first movable arm 1, and the second lever arm 42 of the first elastic member 4 is connected to the first end 21.
[0064] Alternatively, if the first elastic element includes at least two helical portions 40, a third lever arm 43 and two fourth lever arms 44, the third lever arm 43 of the first elastic element 4 is connected to the first movable arm 1, and the fourth lever arm 44 of the first elastic element 4 is connected to the first end 21.
[0065] Alternatively, if the second elastic member 5 includes a spiral portion 40, a first lever arm 41, and a second lever arm 42, the spiral portion 40 of the second elastic member 5 is disposed between the second end 22 and the third movable arm 3, the first lever arm 41 of the second elastic member 5 is connected to the second end 22, and the second lever arm 42 of the second elastic member 5 is connected to the third movable arm 3.
[0066] Alternatively, when the second elastic element 5 includes at least two helical portions 40, a third lever arm 43, and two fourth lever arms 44, the third lever arm 43 of the second elastic element 5 is connected to the second end 22, and the fourth lever arm 44 of the second elastic element 5 is connected to the third movable arm 3. The multiple helical portions 40 increase the elastic performance, thereby increasing the elastic force applied when the first elastic element 4 and the second elastic element 5 undergo elastic deformation, ensuring the smooth reset of the second movable arm 2 and the third movable arm 3.
[0067] Referring to Figures 2 and 6 together, in some embodiments, both the first movable arm 1 and the second end 22 are provided with a slot 10, which is inserted and engaged with the first lever arm 41 or the third lever arm 43.
[0068] Both the first end 21 and the third movable arm 3 are provided with locking holes 211. Each second lever arm 42 corresponds to one locking hole 211, or each fourth lever arm 44 corresponds to one locking hole 211. The locking holes 211 are inserted into the second lever arm 42 or the fourth lever arm 44. The first lever arm 41 and the second lever arm 42, or the third lever arm 43 and the fourth lever arm 44 are inserted into their respective hole structures. On the one hand, this stabilizes the connection of the spiral part 40, and on the other hand, it also hides the first lever arm 41 and the second lever arm 42, or the third lever arm 43 and the fourth lever arm 44, so as to prevent them from interfering when the second movable arm 2 and the third movable arm 3 are folded.
[0069] Referring to Figure 2, in some embodiments, the cable management device further includes a first rotating shaft 103 and a second rotating shaft 104. The first rotating shaft 103 is connected to the first movable arm 1, and the axis of the first rotating shaft 103 is parallel to the second direction Y. The first end 21 passes through the first rotating shaft 103. The second movable arm 2 is rotatably connected to the first movable arm 1 through the first rotating shaft 103. The spiral part 40 of the first elastic member 4 is sleeved on the first rotating shaft 103. Specifically, the first movable arm 1 has mounting holes 11 on both sides along the second direction Y. The first rotating shaft 103 includes a shaft 1031, a thrust part 1032, and a fixing screw 1033. The shaft 1031 passes through the two mounting holes 11. One end of the shaft 1031 is connected to the thrust part 1032, and the other end is threadedly connected to the fixing screw 1033. The diameter of the thrust part 1032 and the diameter of the head of the fixing screw 1033 are both larger than the diameter of the mounting holes 11, forming a limit on the shaft 1031, thereby restricting the shaft 1031 from disengaging from the mounting holes 11 and realizing the connection between the first rotating shaft 103 and the first movable arm 1. The first end 21 passes through the shaft 1031 and is located between the two mounting holes 11. At this time, the spiral part 40 is sleeved on the shaft 1031. The second movable arm 2 has a clearance space at the position corresponding to the spiral part 40 to allow the spiral part 40 to be inserted. In some other embodiments, a thrust portion 1032 is provided at each end of the shaft 1031. The thrust portion 1032 can be formed by riveting the ends of the shaft 1031. During assembly, one end of the shaft 1031 is riveted first, and the other end passes through the two assembly holes 11 and is then riveted, thus connecting the shaft 1031 to the first movable arm 1. The second rotating shaft 104 is connected to the second end 22, and the third movable arm 3 is rotatably connected to the second movable arm 2 through the second rotating shaft 104. The connection structure of the second rotating shaft 104 to the second end 22 and the third movable arm 3 can be referred to the first rotating shaft 103, and will not be described again here.
[0070] Referring to Figures 7 and 8, in some embodiments, the second movable arm 2 includes multiple sub-sections 20, which are sequentially connected end-to-end, with each adjacent pair of sub-sections 20 rotatably connected. The sequential connection of the multiple sub-sections 20 means that each sub-section 20 is arranged sequentially along a certain direction between the first movable arm 1 and the third movable arm 3, with the tail of each sub-section 20 connected to the head of the next sub-section 20, forming a whole. The head and tail correspond to the two ends of each sub-section 20.
[0071] The cable management device also includes a third elastic element 7, which connects two adjacent sub-sections 20. When the third elastic element 7 is in its natural state, each sub-section 20 folds over the others. The structure and connection method of the third elastic element 7 are the same as those of the first elastic element 4 and the second elastic element 5, and will not be described again here.
[0072] Specifically, the first-level sub-part 20 is provided with a first end 21, and the last-level sub-part 20 is provided with a second end 22. The multi-level sub-parts 20 have a folded state and an unfolded state. In the folded state, the multi-level sub-parts 20 are arranged along the first direction X, and the third elastic member 7 is in a natural state. The first direction X is the thickness direction of the first movable arm 1. In the unfolded state, the third elastic member 7 undergoes elastic deformation. The first-level sub-part 20 and the last-level sub-part 20 refer to the two outermost sub-parts 20 in the arrangement direction of the multi-level sub-parts 20. They can also be understood as the sub-part 20 closest to the first movable arm 1 and the sub-part 20 closest to the third movable arm 3 in the folded or unfolded state.
[0073] When folded, each sub-section 20 overlaps with the others and is stacked on the first movable arm 1. The third movable arm 3 overlaps on the sub-section 20. The multi-level sub-section 20 increases the length of the device when unfolded, enabling the device to accommodate the wide range of movement of the cable 102 and improving the device's adaptability to different usage scenarios.
[0074] In some embodiments, the cable management device further includes a rope 8, which includes a first rope end 81 and a second rope end 82 disposed opposite to each other. The first rope end 81 is connected to the third movable arm 3, and the second rope end 82 is connected to the clamping member 6. The rope 8 is made of soft metal rope. When the cable 102 moves, the clamping member 6 can have a large range of motion to avoid interference with the third movable arm 3. At the same time, it can also play a buffering role, reducing the impact of the cable 102 tension on the connection between the clamping member 6 and the third movable arm 3.
[0075] Referring to Figures 2 and 9, in some embodiments, the third movable arm 3 includes a body portion 31 and a receiving portion 32. The receiving portion 32 is disposed at one end of the body portion 31 away from the second elastic member 5, and the other end of the body portion 31 is rotatably connected to the second end 22. The receiving portion 32 is provided with a first opening 321 communicating with its interior. The cable management device also includes a limiting member 9, which is disposed within the receiving portion 32. The limiting member 9 includes a lifting rod 91 and a limiting portion 92. The lifting rod 91 is connected to the inner wall of the receiving portion 32. The rope 8 passes through the first opening 321 and is connected to the lifting rod 91 through a first rope end 81, so that the rope 8 is connected to the third movable arm 3 through the lifting rod 91. The width of the first opening 321 is greater than the diameter of the rope 8.
[0076] The first rope end 81 is clamped in the limiting part 92 to restrict the displacement of the first rope end 81 in the length direction of the boom 91. Specifically, the boom 91 is arranged along the thickness direction of the third movable arm 3, and two limiting parts 92 are provided, distributed on both sides of the first rope end 81. The orthographic projection of the boom 91 along the thickness direction of the third movable arm 3 onto the limiting part 92 is located inside the outer peripheral edge of the limiting part 92, so that the limiting part 92 can clamp the rope 8. At this time, the first opening 321 is located between the clamping member 6 and the boom 91. In addition to allowing the rope 8 to pass through and enter the receiving part 32, the first opening 321 also restricts the left and right swaying of the rope 8 within a certain range, which helps to improve the stability of the clamping member 6.
[0077] Referring to Figures 2 and 9, in some embodiments, the third movable arm on the side surface of the receiving portion 32 is provided with a second opening 322 that communicates internally. That is, the second opening 322 is located on the end face of the third movable arm of the receiving portion 32 away from the second elastic member 5. The second opening 322 communicates with the first opening 321. The surface where the second opening 322 is located is at an angle to the surface where the first opening 321 is located, so that the second opening 322 and the first opening 321 form an L-shape. When the cable 102 is pulled, the clamping member 6 is subjected to the tension of the cable 102 and pulls the third movable arm 3 to rotate through the rope 8. When the third movable arm 3 rotates to the direction of the tension it receives, the rope 8 slides from the first opening 321 to the second opening 322, keeping it as straight as possible with the tension, reducing the angle between the rope 8 and the direction of the tension, which helps the rope 8 avoid repeated large-angle bending with the edge of the first opening 321, thus protecting the rope 8.
[0078] Referring to Figures 2 and 9, in some embodiments, there are two limiting members 9, and the two limiting members 9 are spaced apart along the second direction Y. The third movable arm of the receiving part 32 is provided with two first openings 321 and two second openings 322. The two first openings 321 are respectively provided on both sides of the third movable arm of the receiving part 32 along the second direction Y. That is, one first opening 321 is provided on the upper side of the receiving part 32, and the other first opening 321 is provided on the lower side of the receiving part 32.
[0079] Both second openings 322 are located on the side surface of the third movable arm of the receiving part 32. Each first opening 321 connects to one second opening 322 and is correspondingly provided with a limiting member 9. When installing cable management devices on a charging pile, they are usually installed symmetrically on both sides, so the clamping members 6 of the two cable management devices are located on the same side. By providing two sets of interconnected first openings 321 and second openings 322, the ropes 8 on both sides of the charging pile can pass downward through the first openings 321 and can also move within the range of the second openings 322 according to the change of tension angle.
[0080] Referring to Figures 2 and 9, in some embodiments, the clamping member 6 includes, but is not limited to, a clamp, a snap clamp, or a hose clamp. For example, the clamping member 6 adopts a snap clamp structure, comprising two clamping plates 61, two sleeves 62, and fasteners. The clamping plates 61 are arc-shaped and hinged together.
