Description

[0001] The present invention relates to the technical field related to wire take-up devices, and in particular to a charging data cable take-up device. Background Art

[0002] In the prior art, the structural design of the charging data cable retractable box often fails to fully consider the contact friction between the data cable and the inside of the box. This type of design has significant defects in practical applications, mainly reflected in the friction between the data cable and the box body when the data cable is retracted, resulting in unsmooth product operation, and the wire is prone to wear and damage due to continuous friction, thus affecting the service life and electrical performance.

[0003] Specifically, traditional telescopic boxes usually adopt a design that directly wraps the data cable around an internal reel or spring to achieve the automatic telescopic function of the data cable. However, in this way, the data cable will inevitably come into direct contact with the inner wall, cover or other internal structure of the box during the telescopic process, causing friction. This friction not only increases the resistance to the telescopic expansion of the data cable, making the operation feel poor and reducing the user experience, but also causes severe wear on the outer skin of the data cable due to long-term repeated expansion and contraction, which in turn affects the electrical connection stability of the internal wires and shortens the overall service life of the data cable.

Detailed implementation manners

[0033] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0034] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs.

[0035] In the present invention, unless otherwise stated, the orientation terms such as "upper, lower, top, bottom" are generally in reference to the direction shown in the drawings, or in reference to the vertical, perpendicular or gravitational direction of the component itself; similarly, for the sake of easy understanding and description, "inner, outer" refer to the inner and outer of the contour of each component itself, but the above orientation terms are not used to limit the present invention.

[0036] In order to solve the problem that in the prior art, there is friction between the charging data cable and the housing of the charging data cable winding device, resulting in damage to the charging data cable and affecting the normal use of the product, the present invention provides a charging data cable winding device.

[0037] Among them, the charging data cable 30 is telescopically arranged inside the housing 10 of the charging data cable winding device. When charging a mobile phone, computer, etc., the charging data cable 30 can extend out of the housing 10 to a preset length, and when not in use, the charging data cable 30 can be retracted and accommodated inside the housing 10 of the charging data cable winding device, which is convenient for carrying and reduces the occupation of space.

[0038] As Figures 1 to 9 shown, the charging data cable winding device of the present application includes a housing 10, a turntable 20, a first circuit board 50, a charging data cable 30, a second circuit board 60 and a reset member 40. An outlet 101 is provided on the outer peripheral surface of the housing 10. The turntable 20 is rotatably arranged inside the housing 10. The reset member 40 is arranged between the turntable 20 and the housing 10 and is used to provide a driving force for the turntable 20 to rotate back to its original position. The first circuit board 50 is arranged on one side of the turntable 20 in the axial direction. An annular installation cavity 80 that is connected between the first circuit board 50 and the turntable 20 and communicates with the outlet 101 is formed. Along the axial direction of the turntable 20, the extension distance of the installation cavity 80 is less than the extension distance of the outlet 101. The second circuit board 60 is arranged on the side of the first circuit board 50 facing away from the turntable 20. The second circuit board 60 is fixedly arranged on the housing 10. The first circuit board 50 is electrically connected to the second circuit board 60.

[0039] Among them, the reset member 40 is a torsion spring. The setting of the torsion spring is used to provide a driving force for the turntable 20 to rotate back to its original position. When the external force applied to the charging data cable 30 disappears, the torsion spring drives the turntable 20 to rotate back to its original position, and the turntable 20 drives the charging data cable 30 and the first circuit board 50 to rotate, so as to wind up the charging data cable 30.

[0040] The cable winding device for the charging data cable of the present application adopts the arrangement of the charging data cable 30 inside the installation cavity 80 formed between the turntable 20 and the first circuit board 50. During the telescoping process of the charging data cable 30, the contact friction between the charging data cable 30 and the housing 10 is reduced, avoiding the problems of the unsmooth telescoping process of the charging data cable in the prior art and the damage of the charging data cable caused by the frictional force.

[0041] In this embodiment, the distance of the installation cavity 80 along the axis of the turntable 20 is shown as Figure 4 H2 in, and the extended distance of the wire outlet 101 along the axis of the turntable 20 is shown as Figure 1 H1 in, where H2 is set to be less than H1 to ensure that during the telescoping process of the charging data cable 30, the charging data cable 30 always remains non-contact with the housing 10, avoiding the friction between the charging data cable 30 and the housing 10 at the wire outlet 101, which is beneficial to improving the safety of the charging data cable 30 during use. At the same time, the smoothness of the telescoping movement of the charging data cable 30 is also improved, enhancing the convenience of use.

[0042] In this embodiment, along the axis of the turntable 20, the projection of the charging data cable 30 wound inside the installation cavity 80 on the turntable 20 is located inside the projection of the first circuit board 50 on the turntable 20. Furthermore, it is ensured that the outer edge of the wound charging data cable 30 is located inside the outer edges of the first circuit board 50 and the turntable 20, so that the charging data cable 30 inside the installation cavity 80 does not protrude radially from the first circuit board 50 and the turntable 20 along the axis of the turntable 20, avoiding the contact friction between the charging data cable 30 and the housing 10. The settings of the turntable 20 and the first circuit board 50 of the present application ensure the safety of the charging data cable 30.

[0043] As shown in Figure 2 、 Figure 4 、 Figure 5 、 Figure 7 shown, the turntable 20 has an annular protrusion 210 extending along the axis of the turntable 20. The first circuit board 50 is arranged at the end of the annular protrusion 210. The installation cavity 80 is formed on the outer peripheral side of the annular protrusion 210, and the charging data cable 30 is wound around the annular protrusion 210.

[0044] Among them, the annular protrusion 210 is rotatably arranged inside the housing 10. The charging data cable 30 is wound around the annular protrusion 210, and the setting of the annular protrusion 210 can realize the formation of the annular installation cavity 80, thereby realizing the synchronous rotation of the charging data cable 30 and the first circuit board 50 when the annular protrusion 210 rotates.

[0045] In this embodiment, the first circuit board 50 is in a disc-shaped structure. The first circuit board 50 is coaxially arranged with the annular protrusion 210. The first circuit board 50 has a mounting plate section 540 that blocks the end opening of the annular protrusion 210, and the mounting plate section 540 is snap-fitted and fixed to the annular protrusion 210.

[0046] Specifically, the mounting plate section 540 has a snap hole 520, and the annular protrusion 210 has an elastic snap 212. The elastic snap 212 is snap-fitted in the snap hole 520 to form a snap-fitting structure, so as to realize the fixed connection between the first circuit board 50 and the annular protrusion 210.

[0047] In order to further improve the installation efficiency and stability of the first circuit board 50 and the annular protrusion 210, positioning posts 211 are provided on the annular protrusion 210, and the mounting plate section 540 of the first circuit board 50 has positioning grooves 530. At least a part of the positioning posts 211 can extend into the interior of the positioning grooves 530 to achieve positioning installation.

[0048] Of course, in this embodiment, the structure between the first circuit board 50 and the annular protrusion 210 is not limited to a snap-fitting structure, and a fastener such as a bolt can also be used to achieve fixed connection.

[0049] As Figure 7 shown, the turntable 20 further includes a disc body portion 200. The annular protrusion 210 is arranged on the end face of the disc body portion 200. The disc body portion 200 and the first circuit board 50 are respectively arranged at both ends of the annular protrusion 210 to form an installation cavity 80.

[0050] Among them, the setting of the disc body portion 200 realizes the effect of limiting the charging data line 30 between the disc body portion 200 and the first circuit board 50. Furthermore, it is ensured that during the telescopic process of the charging data line 30, the part of the charging data line 30 located inside the housing 10 will not be scattered.

[0051] Furthermore, the outer peripheral surface of the disc body portion 200 is spaced from the outer peripheral surface of the housing 10. Furthermore, it is ensured that the turntable 20 can rotate smoothly inside the housing 10 without being affected by the housing 10, which is beneficial to improving the operation stability of the overall structure.

[0052] Specifically, the projection of the charging data line 30 on the disc body portion 200 is located in the inner area of the outer edge of the disc body portion 200, so as to ensure that the charging data line 30 does not protrude beyond the outer edge of the disc body portion 200 along the radial direction of the turntable 20. Furthermore, the charging data line 30 can be protected by the cooperation of the turntable 20 and the first circuit board 50, and the phenomenon of wear of the charging data line 30 caused by contact with the inner surface of the housing 10 can be avoided.

[0053] In this embodiment, the first circuit board 50 is coaxially arranged with the disk body portion 200 and the annular protrusion 210, thereby ensuring the stability of the rotational cooperation between the first circuit board 50 and the turntable 20.

[0054] In this embodiment, the first circuit board 50 and the disk body portion 200 are arranged in parallel to facilitate the formation of a regular installation cavity 80, thereby facilitating the uniform winding of the charging data cable 30 inside the installation cavity 80 and facilitating the telescopic movement of the charging data cable 30.

[0055] As Figure 2 、 Figure 7 and Figure 8 shown, the disk body portion 200 has a rotating hole 201, and the housing 10 has a convex column 121 extending into the rotating hole 201. The convex column 121 is rotationally engaged with the rotating hole 201.

[0056] Specifically, the housing 10 includes a detachable first cover body 110 and a second cover body 120. The wire outlet 101 is arranged between the first cover body 110 and the second cover body 120. The first cover body 110 and the second cover body 120 cooperate to form a receiving cavity for receiving the turntable 20 and the charging data cable 30, and form a wire outlet 101 for the charging data cable 30 to extend out.

[0057] Among them, the connection manner between the first cover body 110 and the second cover body 120 can be a snap-fit structure or can be fixedly connected by fasteners such as bolts.

[0058] In this embodiment, the second cover body 120 has a convex column 121 coaxial with the turntable 20. The first cover body 110 has a groove 113 with the notch facing the second cover body 120. The convex column 121 sequentially passes through the rotating holes of the first circuit board 50 and the turntable 20 and is inserted and engaged with the groove 113, thereby realizing the rotation of the turntable 20 and the first circuit board 50 inside the housing 10. Among them, in order to ensure the structural strength of the first cover body 110, the first cover body 110 has a boss 112 coaxial with the convex column 121, and the groove 113 is arranged on the boss 112 and is coaxial with the boss 112.

[0059] In this embodiment, the reset member 40 is a coil spring. The reset member 40 is arranged inside the annular protrusion 210 and one end is fixedly connected to the convex column 121 and the other end is fixedly connected to the annular protrusion 210. Specifically, the convex column 121 has a clamping slot 1211, and one end of the reset member 40 is clamped and fixed inside the clamping slot 1211.

[0060] As Figure 2 、 Figure 8 and Figure 9 shown, the second circuit board 60 is arranged on the second cover body 120.

[0061] The second cover 120 has a card slot 122, and the second circuit board 60 is arranged at the card slot 122 to be fixed on the second cover 120 by card connection. In order to ensure the stability of the installation of the second circuit board 60, the second circuit board 60 can be further fixed by fasteners such as bolts.

[0062] Specifically, one end of the charging data cable 30 extends from the outlet 101 to connect to an external device to be charged; the other end of the charging data cable 30 is welded and fixed to the first circuit board 50 to achieve electrical connection, and the first circuit board 50 always remains electrically connected to the second circuit board 60 during the rotation process.

[0063] The charging data cable take-up device of the present application adopts a split structural setting of the first circuit board 50 and the second circuit board 60. The first circuit board 50 is set on the turntable 20, so that the turntable 20, the charging data cable 30 and the first circuit board 50 form a rotating whole located inside the shell 10. The turntable 20 and the first circuit board 50 provide a bearing space for the installation of the charging data cable 30. At the same time, the turntable 20 and the first circuit board 50 also have the effect of limiting and protecting the charging data cable 30, thereby improving the convenience and safety of use.

[0064] In this embodiment, the first circuit board 50 and the second circuit board 60 are connected by signals. The first circuit board 50 is fixed on the turntable 20, and the second circuit board 60 is fixed on the second cover 120, so that the first circuit board 50 and the second circuit board 60 form two independent parts. Since the first circuit board 50 of the present application rotates with the turntable 20, the conductive coil 510 on the first circuit board 50 of the present application is arranged on the side facing the second circuit board 60. The arrangement of the circular conductive coil 510 is conducive to the conductive coil 510 being able to always maintain contact with the elastic conductive member 610 on the second circuit board 60 to achieve signal connection during the rotation of the first circuit board 50. The elastic conductive member 610 can be an elastic tongue.

[0065] In this embodiment, a conductive coil 510 is provided on the end surface of the first circuit board 50 facing away from the turntable 20, and an elastic conductive member 610 abutting against the conductive coil 510 is provided on the second circuit board 60. Since the elastic conductive member 610 is elastic, it can always abut against the first circuit board 50 during the rotation of the first circuit board 50; and the first circuit board 50 is provided with a ring-shaped conductive coil 510 for electrical connection with the second circuit board 60, thereby ensuring that the first circuit board 50 can maintain a uniform and stable electrical connection with the second circuit board 60 when rotating.

[0066] like Figure 8 As shown, the second circuit board 60 has two elastic conductive members 610 symmetrically arranged about the protrusion 121 .

[0067] Specifically, the structural arrangement of the symmetrically arranged elastic conductive members 610 is conducive to improving the contact stability between the first circuit board 50 and the second circuit board 60. Among them, the conductive coil 510 is arranged in a multi-turn structure, and the elastic conductive member 610 contacts the outer conductive coil 510, which can ensure that the first circuit board 50 remains balanced when rotating.

[0068] As Figure 3 and Figure 6 shown, the charging data cable retracting device of the present application further includes a limiting member 70.

[0069] Specifically, on the end face of the turntable 20 facing away from the data cable, there are an annular inner ring track 220, an outer ring track 230, and a stop island structure 240 arranged in the communication area between the inner ring track 220 and the outer ring track 230. The limiting member 70 is arranged between the end faces of the housing 10 and the turntable 20. The housing 10 is locked with the stop island structure 240 through the limiting member 70, or the limiting member 70 switches between the inner ring track 220 and the outer ring track 230 through the stop island structure 240.

[0070] In the present application, by arranging the stop island structure 240 on the turntable 20, the extension and locking of the charging data cable 30 during the telescopic process can be controlled through the stop island structure 240, without the need for an external locking member arranged on the housing 10 for locking, avoiding damage to the charging data cable 30 and the problem that the charging data cable 30 cannot be smoothly pulled out due to friction.

[0071] Specifically, the charging data cable retracting device of the present application adopts the structural arrangement of the inner ring track 220, the outer ring track 230, and the stop island structure 240. By the limiting member 70 being in different positions, the charging data cable 30 can be fully pulled out, fully retracted, or the charging data cable 30 can be stretched to a preset length. The housing 10 of the present application is locked with or moves relative to the turntable 20 through the limiting member 70. Specifically, the stop island structure 240 on the turntable 20 can be locked with the housing 10 through the limiting member 70, thereby precisely controlling the extension length of the charging data cable 30. And the stop island structure 240 of the present application is arranged inside the housing 10 and does not directly contact the charging data cable 30, avoiding the problems of easy jamming in the prior art and damage to the charging data cable 30 due to friction of the charging data cable 30.

[0072] The present application adopts the inner ring track 220 and the outer ring track 230 to provide two different movement tracks for the limiting member 70. When the limiting member 70 moves in different tracks, the corresponding turntable 20 rotates clockwise or counterclockwise, thereby facilitating the extension or retraction movement of the charging data cable 30 and improving the convenience of use.

[0073] In this embodiment, the housing 10 and the turntable 20 cooperate to limit the movement of the limiting member 70. The housing 10 and the turntable 20 have the effect of restricting the movement of the limiting member 70, thereby enabling the limiting member 70 at different positions to move in different tracks.

[0074] As Figure 3 shown, on the end face of the turntable 20, there is an arc-shaped partition 250 structure provided between the inner ring track 220 and the outer ring track 230. A notch is formed between the two ends of the partition 250 structure, and the inner ring track 220 and the outer ring track 230 are connected through the notch.

[0075] Among them, the partition 250, the inner ring track 220, and the outer ring track 230 are all arranged coaxially with the turntable 20. The partition 250 is provided to separate the inner ring track 220 and the outer ring track 230.

[0076] Specifically, a notch is formed by spacing between the first end and the second end of the partition 250, that is, the first and last connecting segments. The inner ring track 220 and the outer ring track 230 are connected through the notch to enable the limiting member 70 to switch between the inner ring track 220 and the outer ring track 230, so as to ensure that the charging data cable 30 can be fully extended or fully retracted into the interior of the housing 10.

[0077] In this embodiment, the stop island structure 240 is provided at the notch. When the limiting member 70 moves to the notch position, the stop island structure 240 can lock with the limiting member 70 to stop the turntable 20 from rotating. Alternatively, the stop island structure 240 is used to guide the limiting member 70 located inside the inner ring track 220 to the outer ring track 230, realizing the transfer of the position of the limiting member 70.

[0078] As Figure 3 shown, along the circumferential direction of the turntable 20, one end of the stop island structure 240 has a stop groove 241 and the other end has a guiding portion. The stop groove 241 is connected to the inner ring track 220 and the outer ring track 230. The guiding portion is used to guide the limiting member 70 from the inner ring track 220 to the outer ring track 230. On one side of the end face of the housing 10 facing the turntable 20, there is a limiting groove 111 extending along the radial direction of the turntable 20. A part of the limiting member 70 is movably arranged inside the limiting groove 111, and another part of the limiting member 70 is arranged in the inner ring track 220 or the outer ring track 230 or the stop groove 241.

[0079] Among them, the first cover 110 is an upper cover. The first cover 110 has a limiting groove 111, and the limiting groove 111 is used to limit the moving direction and moving distance of the limiting member 70. The linearly arranged limiting groove 111 enables the limiting member 70 to only move reciprocally along the extending direction of the limiting groove 111, that is, the radial direction of the turntable 20.

[0080] In this embodiment, along the direction of the notch orientation of the stop groove 241, the distance between the two groove side surfaces of the stop groove 241 gradually increases to form a flared structure. The bottom of the stop groove 241 can be used to accommodate the limiting member 70. When the limiting member 70 is located inside the stop groove 241 and the stop groove 241 drives the limiting member 70 to move along the direction of the notch orientation of the stop groove 241, the notch of the stop groove 241 is arranged along the circumferential direction of the turntable 20. At this time, under the limiting action of the limiting groove 111, the limiting member 70 abuts and is fixed inside the stop groove 241.

[0081] In this embodiment, the extension length of the groove side surface of the stop groove 241 close to the inner ring track 220 is less than the extension length of the groove side surface of the stop groove 241 close to the outer ring track 230. The groove side surface on the side close to the outer ring track 230 has a guiding function, so that the limiting member 70 can enter the inside of the stop groove 241 along the groove side surface from the outer ring track 230; the groove side surface on the side close to the inner ring track 220 is used to stop the limiting member 70, so there is no need to set a too long wall surface to affect the movement of the limiting member 70 inside the inner ring track 220.

[0082] In this embodiment, at least a part of the groove side surface of the stop groove 241 close to the inner ring track 220 is arranged opposite to the first guiding surface 251. To ensure that the first guiding surface 251 can contact the limiting member 70 during the rotation of the turntable 20, and is used to guide the limiting member 70 to the inner ring track 220.

[0083] Specifically, the first end of the partition plate 250 is arranged opposite to the stop groove 241, that is, the notch of the stop groove 241 is arranged towards the first end of the partition plate 250 structure. The extension length of the side surface of the first end of the partition plate 250 towards the inner ring track 220 is less than the extension length of the side surface of the first end of the partition plate 250 towards the inner ring track 220. The end of the first end of the partition plate 250 structure is formed into an angular structure with the first guiding surface 251. The limiting member 70 is locked between the stop groove 241 and the limiting groove 111, or the limiting member 70 moves from the stop groove 241 to the inner ring track 220 through the first guiding surface 251.

[0084] In this embodiment, the guiding portion is formed into a sharp corner structure. The radian of the side surface of the guiding portion facing the outer ring track 230 is greater than the radian of the side surface of the guiding portion facing the inner ring track 220. The side surface of the guiding portion facing the outer ring track 230 forms a second guiding surface 242. The limiting member 70 is guided from the inner ring track 220 to the outer ring track 230 through the second guiding surface 242. The second guiding surface 242 is an arc surface structure, so that the limiting member 70 can move along the guiding surface after contacting the second guiding surface 242.

[0085] In this embodiment, in the direction of the line connecting the pointed corner structure and the center of the turntable 20, the pointed corner structure and the partition 250 at least partially overlap, so that when the limiting member 70 moves to the position of the pointed corner structure, the second guiding surface 242 can contact the limiting member 70 to achieve the guiding effect.

[0086] The first guiding surface 251 is used to guide the limiting member 70 to move from the stop groove 241 to the inner ring track 220, and the second guiding surface 242 is used to guide the limiting member 70 inside the inner ring track 220 to the inside of the outer ring track 230. Furthermore, the setting of the stop island structure 240 has the effect of realizing the switching of the limiting member 70 between the inner ring track 220 and the outer ring track 230, so as to ensure that the charging data cable 30 can be fully stretched.

[0087] In this embodiment, the structure of the limiting member 70 can be a ball or a convex shaft; when the limiting member 70 is a ball, the ball is rollingly arranged inside the limiting groove 111 of the housing 10 and the inner ring track 220 or the outer ring track 230 of the turntable 20; when the limiting member 70 is a convex shaft, the convex shaft is slidably arranged inside the limiting groove 111 of the housing 10 and the inner ring track 220 or the outer ring track 230 of the turntable 20.

[0088] In this embodiment, as Figure 1 and Figure 3 shown in the views, when the charging data cable 30 is stretched, the turntable 20 rotates counterclockwise, and when the charging data cable 30 retracts under the action of the reset member 40, the turntable 20 rotates clockwise; when the charging data cable 30 is pulled, since the housing 10 is fixed, the limiting member 70 can only be used to move along the limiting groove 111.

[0089] When the limiting member 70 is in the inner ring track 220 of the turntable 20, if the charging data cable 30 is continuously pulled, the turntable 20 will rotate counterclockwise. When it rotates to the stop island structure 240 on the turntable 20, the guiding portion will cause the limiting member 70 to move into the outer ring track 230 on the turntable 20; at this time, if the charging data cable 30 is released, under the action of the restoring force of the reset member 40, the turntable 20 rotates clockwise. When it rotates to the stop island structure 240, it will enter the inside of the stop groove 241, and at this time the turntable 20 stops rotating to reach the length desired by the user. If the charging data cable 30 is pulled continuously, at this time the limiting member 70 moves to the inner ring track 220 under the guidance of the first guiding surface 251 of the partition 250. When the limiting member 70 reaches the inner ring track 220 and the charging data cable 30 is released, under the action of the reset member 40, the turntable 20 rotates clockwise, and under the guidance of the inner ring track 220, the charging data cable 30 will be fully retracted and accommodated inside the housing 10.

[0090] When the limiting member 70 is on the outer ring track 230 of the turntable 20, if the charging data cable 30 is continuously pulled, the turntable 20 rotates counterclockwise and can be pulled to the end. When the charging data cable 30 is released, under the action of the reset member 40, the turntable 20 rotates clockwise. When it rotates to the stop island structure 240, the limiting member 70 enters the inside of the stop groove 241 and the turntable 20 stops. If the charging data cable 30 is pulled again, the limiting member 70 moves to the inner ring track 220 under the guidance of the first guiding surface 251 of the partition plate 250, entering the situation when the limiting member 70 is on the inner ring track 220 of the turntable 20, and the movement is repeated.

[0091] It can be understood that when the inner ring track 220 on the turntable 20 rotates clockwise, the limiting member 70 cannot move into the outer groove track.

[0092] It should be noted that the clockwise and counterclockwise directions in this embodiment are based on the illustrated situation.

[0093] In this embodiment, after the limiting member 70 enters the inside of the clamping groove, without applying artificial external force, the housing 10 locks the turntable 20 through the cooperation of the limiting groove 111 and the clamping groove; after applying external force, the limiting member 70 moves along the first guiding surface 251 to the inside of the inner ring track 220 under the drive of the external force.

[0094] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0095] The charging data cable retracting device of the present application is configured by arranging the charging data cable 30 inside the installation cavity 80 formed between the turntable 20 and the first circuit board 50. During the telescoping process of the charging data cable 30, the contact friction between the charging data cable 30 and the housing 10 is reduced, avoiding the problems of unsmooth telescoping of the charging data cable in the prior art and damage to the charging data cable due to frictional force.

[0096] The charging data cable retracting device of the present application adopts the structural settings of the inner ring track 220, the outer ring track 230, and the stop island structure 240. By the limiting member 70 being in different positions, the charging data cable 30 can be fully pulled out, fully retracted, or stretched to a preset length. The housing 10 of the present application locks or moves relative to the turntable 20 through the limiting member 70. Specifically, the stop island structure 240 on the turntable 20 can be locked with the housing 10 through the limiting member 70, thereby accurately controlling the extended length of the charging data cable 30. Moreover, the stop island structure 240 of the present application is arranged inside the housing 10 and does not directly contact the charging data cable 30, avoiding the problems of easy jamming and damage to the charging data cable 30 due to frictional force in the prior art.

[0097] This application uses the inner ring track 220 and the outer ring track 230 to provide two different movement tracks for the limiting member 70. When the limiting member 70 moves in different tracks, the corresponding turntable 20 rotates clockwise or counterclockwise, thereby facilitating the extension or retraction movement of the charging data cable 30 and improving the convenience of use.
