DETAILED DESCRIPTION

[0048] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making any creative work are within the scope of protection of this application.

[0049] In the description of the present application, it should be understood that the terms "height", "thickness", "up", "down", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present application. In the description of the present application, "multiple" means two or more, and at least one means one, two or more, unless otherwise clearly and specifically defined. In the description of the present application, "parallel" means completely parallel or almost completely parallel. For example, anything within a 10° range of complete parallelism is considered parallel.

[0050] It should also be noted that in the drawings of the embodiments of the present application, the arrow marked X represents the first direction X, and the arrow marked Y represents the second direction Y. The first direction X and the second direction Y are introduced to more clearly illustrate the structure and relative positional relationship of the various components in the cable management device. In actual application, the first direction X and the second direction Y may change according to different placement methods of the cable management device.

[0051] Please combine Figure 1 、 Figure 2 and Figure 3 The cable management device of the embodiment of the present application 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 be installed 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.

[0052] The second movable arm 2 includes a first end 21 and a second end 22 that are oppositely disposed. Specifically, the first end 21 and the second end 22 are different ends of the second movable arm 2 along its length. The first end 21 is pivotally connected to the first movable arm 1, and the pivotal connection point between the first end 21 and the first movable arm 1 is located at one end along its length. 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 relative to the first movable arm 1. At this point, 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 along its length. It will be understood that the elastic member is in its natural state, meaning that it is not deformed by external forces.

[0053] The third movable arm 3 is rotatably connected to the second end 22, and the second elastic member 5 is used to connect the second end 22 and the third movable arm 3. When the second elastic member 5 is in a natural state, the third movable arm 3 is folded onto 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.

[0054] The clamping member 6 is provided on the third movable arm 3 and is used to clamp the cable 102 to secure it to the clamping member 6. When tension is applied to the cable 102, the third movable arm 3 and the second movable arm 2 unfold, causing the first elastic member 4 and the second elastic member 5 to elastically deform. The tension applied to the cable 102 is generated by the user pulling on the cable 102 when the charging connector 101 is engaged. It is 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 drives the second movable arm 2 and the third movable arm 3 to rotate and fold.

[0055] The axis of the rotational connection point between the first end 21 and the first movable arm 1 and the axis of the rotational connection point between the second end 22 and the third movable arm 3 are both parallel to the second direction Y. On the one hand, the cable 102 is pulled off the ground by the clamping member 6 , and on the other hand, the movement of the cable 102 is coordinated by the unfolding and folding of the second movable arm 2 and the third movable arm 3 , thereby ensuring the movable range of the cable 102 , reducing the possibility of friction caused by the cable 102 dragging on the ground, and helping to protect the cable 102 from potential safety hazards.

[0056] Please combine Figure 2 and Figure 4 In some embodiments, the cable management device 102 includes at least two resilient members 106 . Each resilient member 106 includes a spiral portion 40 , a first lever arm 41 , and a second lever arm 42 . The spiral portion 40 is formed by spirally winding an elastic material and is cylindrical. It is elastic and flexible, capable of withstanding and storing torsional forces, and exhibits elastic deformation and recovery capabilities. The spiral portion 40 has an axis M parallel to the second direction Y. The first lever arm 41 and the second lever arm 42 are connected at both ends of the spiral portion 40 along the spiral direction. The first lever arm 41 and the second lever arm 42 may be integrally formed with the spiral portion 40.

[0057] Alternatively, the reset elastic member 106 includes at least two spiral portions 40, a third lever arm 43 and two fourth lever arms 44, the spiral portion 40 has an axis M, the two spiral portions 40 are arranged at intervals along the axis M, the third lever arm 43 is arc-shaped and respectively connects the ends of the two spiral portions 40 that are close to each other, and each end of the spiral portion 40 away from the third lever arm 43 is connected to a fourth lever arm 44, wherein the two spiral portions 40, the third lever arm 43 and the two fourth lever arms 44 can be integrally formed.

[0058] When the second movable arm 2 is folded onto the first movable arm 1, the first elastic member 4 is in a natural state, and the angle between the first force arm 41 and the second force arm 42 is 0. When the second movable arm 2 gradually rotates and unfolds, the first force arm 41 and the second force arm 42 are gradually opened under force, and drive the spiral portion 40 to undergo elastic twisting, thereby generating elastic deformation and applying an elastic force on the second movable arm 2 in the opposite direction of the tension it is subjected to.

[0059] Alternatively, when the second movable arm 2 is folded onto the first movable arm 1, the first elastic member 4 is in a natural state, and the angle between the third force arm 43 and the fourth force arm 44 is 0. When the second movable arm 2 gradually rotates and unfolds, the third force arm 43 and the fourth force arm 44 are gradually opened by force, and drive the spiral portion 40 to undergo elastic twisting, thereby generating elastic deformation and applying an elastic force to the second movable arm 2 in the opposite direction of the tension it is subjected to.

[0060] The specific changes of the second elastic member 5 when the third movable arm 3 is in the natural state and the unfolded state refer to the first elastic member 4 and will not be described in detail here.

[0061] Please combine Figure 2 and Figure 5 In some embodiments, when the first elastic member 4 includes a spiral portion 40, a first force arm 41 and a second force arm 42, the spiral portion 40 of the first elastic member 4 is arranged between the first end 21 and the first movable arm 1, the first force arm 41 of the first elastic member 4 is connected to the first movable arm 1, and the second force arm 42 of the first elastic member 4 is connected to the first end 21.

[0062] Alternatively, when the first elastic member includes at least two spiral portions 40 , a third lever arm 43 and two fourth lever arms 44 , the third lever arm 43 of the first elastic member 4 is connected to the first movable arm 1 , and the fourth lever arm 44 of the first elastic member 4 is connected to the first end 21 .

[0063] Alternatively, when the second elastic member 5 includes a spiral portion 40, a first force arm 41 and a second force arm 42, the spiral portion 40 of the second elastic member 5 is arranged between the second end 22 and the third movable arm 3, the first force arm 41 of the second elastic member 5 is connected to the second end 22, and the second force arm 42 of the second elastic member 5 is connected to the third movable arm 3.

[0064] Alternatively, when the second elastic member 5 includes at least two spiral portions 40, a third lever arm 43, and two fourth lever arms 44, the third lever arm 43 of the second elastic member 5 is connected to the second end 22, and the fourth lever arm 44 of the second elastic member 5 is connected to the third movable arm 3. The multiple spiral portions 40 increase the elastic performance, thereby increasing the elastic force exerted when the first elastic member 4 and the second elastic member 5 are elastically deformed, thereby ensuring that the second movable arm 2 and the third movable arm 3 are smoothly reset.

[0065] Please combine Figure 2 and Figure 6 In some embodiments, the first movable arm 1 and the second end 22 are both provided with a card slot 10 , and the card slot 10 is plugged into and matched with the first force arm 41 or the third force arm 43 .

[0066] The first end 21 and the third movable arm 3 are both provided with a latching hole 211. Each second lever arm 42 corresponds to a latching hole 211, or each fourth lever arm 44 corresponds to a latching hole 211. The latching holes 211 are plugged into and mated with 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 plugged into their respective hole structures. This not only stabilizes the connection of the spiral portion 40, but also conceals the first lever arm 41 and the second lever arm 42, or the third lever arm 43 and the fourth lever arm 44, to prevent them from interfering when the second movable arm 2 and the third movable arm 3 are folded.

[0067] Please refer 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 is passed 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 portion 40 of the first elastic member 4 is sleeved on the first rotating shaft 103. Specifically, the first movable arm 1 is provided with assembly holes 11 on both sides along the second direction Y, and the first rotating shaft 103 includes a shaft rod 1031, a thrust portion 1032 and a fixing screw 1033. The shaft rod 1031 passes through the two assembly holes 11, one end of the shaft rod 1031 is connected to the thrust portion 1032, and the other end is threadedly connected to the fixing screw 1033. The diameter of the thrust portion 1032 and the diameter of the head of the fixing screw 1033 are both larger than the diameter of the assembly hole 11, forming a limit for the shaft rod 1031, thereby limiting the shaft rod 1031 from disengaging from the assembly hole 11, thereby realizing the connection between the first rotating shaft 103 and the first movable arm 1; the first end 21 is passed through the shaft rod 1031 and is located between the two assembly holes 11. At this time, the spiral portion 40 is sleeved on the shaft rod 1031, and the second movable arm 2 is provided with an avoidance space at the position corresponding to the spiral portion 40 for the spiral portion 40 to be placed in. In some other embodiments, a thrust portion 1032 is provided at each end of the shaft 1031. The thrust portions 1032 can be formed by riveting the ends of the shaft 1031. During assembly, one end of the shaft 1031 is first riveted, and the other end is then riveted after passing through the two assembly holes 11. In this way, the shaft 1031 is connected 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 via 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 as the first rotating shaft 103, and will not be repeated here.

[0068] Please combine Figure 7 and Figure 8 In some embodiments, the second movable arm 2 includes multiple sub-sections 20, which are sequentially connected end to end, with each adjacent sub-section 20 being rotationally connected. The multiple sub-sections 20 being sequentially connected end to end means that the sub-sections 20 are arranged sequentially along a 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 to form a whole, with the head and tail corresponding to the two ends of the sub-section 20, respectively.

[0069] The cable management device 102 further includes a third elastic member 7, which connects two adjacent sub-sections 20. When the third elastic member 7 is in its natural position, the sub-sections 20 at each level are folded relative to each other. The structure and connection method of the third elastic member 7 are similar to those of the first elastic member 4 and the second elastic member 5, and will not be further described here.

[0070] Specifically, the first-stage sub-section 20 has a first end 21, and the last-stage sub-section 20 has a second end 22. The multi-stage sub-sections 20 have folded and unfolded states. In the folded state, the multi-stage sub-sections 20 are arranged along a 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. When the multi-stage sub-sections 20 are unfolded, the third elastic member 7 undergoes elastic deformation. The first-stage sub-section 20 and the last-stage sub-section 20 refer to the two outermost sub-sections 20 in the arrangement direction of the multi-stage sub-sections 20. They can also be understood as the sub-section 20 closest to the first movable arm 1 and the sub-section 20 closest to the third movable arm 3 in either the folded or unfolded state.

[0071] When in the folded state, the sub-sections 20 at each level overlap with each other and are overlapped as a whole on the first movable arm 1, and the third movable arm 3 overlaps on the sub-section 20. The multi-level sub-sections 20 increase the length of the device when unfolded, so that the device can meet the large range of movement of the cable 102, which is conducive to improving the adaptability of the device to different usage scenarios.

[0072] 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 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 clamp 6. The rope 8 is made of a soft metal rope. When the cable 102 moves, the clamp 6 has a large range of movement to avoid interference with the third movable arm 3. The rope 8 also acts as a buffer, reducing the impact of the cable 102 tension on the connection between the clamp 6 and the third movable arm 3.

[0073] Please combine Figure 2 and Figure 9 In some embodiments, the third movable arm 3 includes a main body 31 and a receiving portion 32. The receiving portion 32 is disposed at one end of the main body 31 away from the second elastic member 5. The other end of the main body 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 further includes a stopper 9 disposed within the receiving portion 32. The stopper 9 includes a suspension rod 91 and a stopper 92. The suspension 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 suspension rod 91 via the first rope end 81, thereby connecting the rope 8 to the third movable arm 3 via the suspension rod 91. The width of the first opening 321 is greater than the diameter of the rope 8.

[0074] The first rope end 81 is clamped in the limiting portion 92 to limit the displacement of the first rope end 81 in the longitudinal direction of the suspension rod 91. Specifically, the suspension rod 91 is arranged along the thickness direction of the third movable arm 3, and there are two limiting portions 92, which are arranged on both sides of the first rope end 81. The orthographic projection of the suspension rod 91 along the thickness direction of the third movable arm 3 on the limiting portion 92 is located inside the outer peripheral edge of the limiting portion 92, so that the limiting portion 92 can clamp the rope 8. At this time, the first opening 321 is located between the clamping member 6 and the suspension rod 91. In addition to allowing the rope 8 to pass through to enter the accommodating portion 32, the first opening 321 also limits the left and right swing of the rope 8 within a certain range, which helps to improve the stability of the clamping member 6.

[0075] Please combine Figure 2 and Figure 9 In some embodiments, the third movable arm on the side surface of the accommodating portion 32 is provided with a second opening 322 that communicates with the interior thereof. Specifically, the second opening 322 is provided on the end surface of the third movable arm of the accommodating 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 angled with the surface where the first opening 321 is located, such 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 rotates the third movable arm 3 through the rope 8. When the third movable arm 3 rotates in the direction of the tension it is subjected to, the rope 8 slides from the first opening 321 to the second opening 322, maintaining a straight line with the tension as much as possible. This reduces the angle between the rope 8 and the direction of the tension, helps the rope 8 avoid repeated bending at large angles with the edge of the first opening 321, and protects the rope 8.

[0076] Please combine Figure 2 and Figure 9 In some embodiments, there are two limit members 9, and the two limit members 9 are spaced apart along the second direction Y. The third movable arm of the accommodating portion 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 accommodating portion 32 along the second direction Y, that is, one first opening 321 is provided on the upper side surface of the accommodating portion 32, and the other first opening 321 is provided on the lower side surface of the accommodating portion 32.

[0077] Two second openings 322 are located on the side surface of the third movable arm of the accommodating portion 32. Each first opening 321 communicates with a second opening 322 and is positioned in correspondence with a stopper 9. When installing a cable management device on a charging pile, it is typically installed symmetrically on both sides, so the clamping members 6 of the two cable management devices are located on the same side.
