[0031] The following embodiments of the technical solution of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of this application.

[0032] It should be noted that, unless otherwise specified, the technical or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.

[0033] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and 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, and therefore should not be understood as a limitation on the present application.

[0034] In addition, the terms "first," "second," etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. In the description of this application, "plurality" means more than two, unless otherwise specifically defined.

[0035] In this application, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components or interactions between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on specific circumstances.

[0036] In this application, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0037] like Figure 1As shown, the retractable wire device includes a base 10, a rotating assembly 20 and a deceleration assembly 30 arranged in the base 10. The rotating assembly 20 is rotatably connected to the base 10 and rotates relative to the base 10. The data cable 40 is wound around the rotating assembly 20 and one end is fixed to the rotating assembly 20. Through the rotation of the rotating assembly 20 and the relevant winding structure, the data cable 40 is driven to be rolled up or unfolded, which facilitates the use and storage of the data cable 40. The base 10 is used to protect the rotating assembly 20. Specifically, the base 10 can be a shell to protect the rotating assembly 20 and the data cable 40. When in use, the data cable 40 extends from or moves in from one end or both ends of the shell as the rotating assembly 20 rotates.

[0038] Furthermore, considering that the winding power provided by the rotating component 20 may be large, which may cause the data cable 40 to be wound up too fast, and may hit or cut the user, thereby affecting the user's safety and usage experience, therefore, in the embodiment of the present application, the deceleration component 30 provides resistance to the rotating component 20 when the rotating component 20 rotates, thereby slowing down the winding speed of the data cable 40 and ensuring user safety.

[0039] Specifically, the deceleration assembly 30 can provide resistance by adsorption, blocking, increasing the friction of rotation, etc. The deceleration assembly 30 is disposed on the rotating assembly 20 and / or the base 10. For example, if the deceleration assembly 3 is a separate damping member disposed on the rotating assembly 20 or the base 10, such as the brake structure of a bicycle, when the rotating assembly 20 rotates, the damping member interferes with the rotating assembly 20, thereby interfering with the rotation of the rotating assembly 20.

[0040] Alternatively, the deceleration assembly 30 can be separately mounted on the base 10 and the rotating assembly 20. The deceleration assembly 30 can be embedded in the base 10 and the rotating assembly 20, respectively, without requiring a separate component on the base 10 or the rotating assembly 20. This allows for deceleration while avoiding the need for the deceleration assembly to occupy the assembly space of the telescopic wire device, which could affect the volume of the device and the user experience. Specifically, when the deceleration assembly 30 is mounted on the base 10 and the rotating assembly 20, a portion of the deceleration assembly 30 is located at one end of the base 10 near the rotating assembly 20, while another portion of the deceleration assembly 30 is located at the other end of the rotating assembly 20 near the base 10. This allows the portions of the deceleration assembly 30 located on the base 10 and the rotating assembly 20 to be closer to each other, resulting in a better damping effect between the base 10 and the rotating assembly 20. In some embodiments, the deceleration structure 30 is a damping member located between the base 10 and the rotating assembly 20. Both the base 10 and the rotating assembly 20 come into contact with the damping member, generating resistance and thereby reducing the rotational speed of the rotating assembly 20. It should be understood that when the deceleration assembly 3 is a separate damping member, the damping member is arranged between the base 10 and the rotating assembly 20, the deceleration assembly 30 is arranged at the part of the base 10 close to one end of the rotating assembly 20, that is, a part of the damping member, and the deceleration assembly 30 is arranged at the other part of the rotating assembly 20 close to the end of the base 10, that is, another part of the damping member.

[0041] Considering the impact of the size and weight of the retractable wire device on the user experience, in order to achieve rotational deceleration in a more lightweight and effective manner, in this embodiment of the application, magnetic attraction is used to provide resistance to the rotating assembly 20. Specifically, the deceleration assembly 30 includes a first magnetic member 50 disposed on the rotating assembly 20 and a second magnetic member 60 disposed on the base 10. The first magnetic member 50 and the second magnetic member 60 are disposed correspondingly, for example, the first magnetic member 50 and the second magnetic member 60.

[0042] By correspondingly arranging the first magnetic member and the second magnetic member 60, when the first magnetic member 50 passes through the adsorption range of the second magnetic member 60 during the rotation of the rotating component 20, the first magnetic member 50 is affected by the adsorption force of the second magnetic member 60, thereby achieving deceleration of the rotating component 20.

[0043] Specifically, in order to ensure sufficient attraction between the second magnetic member 60 and the first magnetic member 50, thereby ensuring the deceleration effect of the deceleration assembly 30, the magnetic poles of the ends of the first magnetic member 50 and the second magnetic member 60 that are close to each other are opposite. For example, the end of the first magnetic member 50 close to the second magnetic member 60 is the N pole, and the end of the second magnetic member 60 close to the first magnetic member 50 is the S pole. The N pole and the S pole attract each other, so that the second magnetic member 60 and the first magnetic member 50 attract each other, causing resistance to the rotation of the rotating assembly 20. In other embodiments, the first magnetic member 50 can be an attracting magnet and the second magnetic member 60 can be a permanent magnet; or the second magnetic member 60 can be an attracting magnet and the first magnetic member 50 can be a permanent magnet. The magnetic member is a metal material or alloy material that can be attracted by a permanent magnet. The attracting magnet is made of metal materials or alloy materials such as iron, cobalt, and nickel that can be attracted by permanent magnets. Permanent magnets, such as magnets, can generate magnetic fields and have the characteristics of attracting metal magnetic materials such as iron, nickel, and cobalt.

[0044] Furthermore, considering that a pair of correspondingly arranged first magnetic members 50 and second magnetic members 60 can only cooperate with each other to be adsorbed when the rotating component 20 rotates to a single specific position, thereby achieving a deceleration effect on the rotating component 20, in order to ensure that there is a relatively continuous and stable deceleration effect throughout the rotation of the rotating component 20, and to avoid the problem that when the rotating component 20 rotates to certain deceleration blind spots, the winding speed is still too fast or the winding speed is fast or slow, the embodiment of the present application is provided with multiple first magnetic members 50 or multiple second magnetic members 60, wherein the multiple first magnetic members 50 are circumferentially spaced on the rotating component 20, or the multiple second magnetic members 60 are circumferentially spaced on the base 10, so that when the rotating component 20 rotates to various angles, there are second magnetic members 60 or first magnetic members 50 arranged at corresponding angular positions to provide resistance to it, thereby achieving comprehensive and effective deceleration of the rotating component 20. Preferably, multiple pairs of first magnetic members 50 and second magnetic members 60 corresponding in position may be provided simultaneously, thereby achieving strong deceleration at various angles of the rotating assembly 20 .

[0045] Specifically, regarding the relative position relationship between the first magnetic component 50 and the second magnetic component 60, the rotating assembly 20 in the embodiment of the present application includes a rotating frame body 210, and the base 10 includes an upper base 110 and a lower base 120; the rotating frame body 210 and the data line 40 are arranged between the upper base 110 and the lower base 120; the second magnetic component 60 is arranged on the lower base 120, and correspondingly, in order to improve the adsorption efficiency between the first magnetic component 50 and the second magnetic component 60, the first magnetic component 50 is arranged on the side of the rotating frame body 210 close to the lower base 120.

[0046] Specifically, the first magnetic member 50 and the second magnetic member 60 may be spaced apart from each other along the rotation axis direction of the rotating frame. Figure 2aSchematic diagram of the relative positions of the retractable wire device and the section line AB provided in the embodiment of the present application. Figure 2b The sectional view of the retractable wire device provided in the embodiment of the present application is taken along the section line AB. The axis direction refers to the direction parallel to the axis of the rotating frame, i.e., the length direction of the axis. Figure 2a as well as Figure 2b As shown, the direction of the rotation axis is perpendicular to Figure 2a The direction of the section line AB in . Figure 3 2 is an exploded view of the retractable wire device provided in an embodiment of the present application.

[0047] To maximize the area of attraction between the first and second magnetic members 50, 60 and improve their efficiency, the first and second magnetic members 50, 60 are positioned relative to each other along the axis of the rotating assembly 20. As a result, when winding the line, the first magnetic member 50 on the rotating assembly 20 rotates with it. When the first magnetic member 50 passes under the second magnetic member 60, the two members attract each other, causing magnetic resistance to the rotating assembly 20 and slowing the winding speed.

[0048] Optionally, the first magnetic member 50 and the second magnetic member 60 may be spaced apart along the radial direction of the rotating assembly, wherein the radial direction refers to a direction perpendicular to the rotation axis of the rotating frame, that is, the width direction of the rotation axis. Figure 4a Schematic diagram of the relative positions of the retractable wire device and the section line CD provided in an embodiment of the present application; Figure 4b : is a cross-sectional view of the retractable wire device provided in the embodiment of the present application under the section line CD. Figure 4a as well as Figure 4b As shown, the direction of the rotation axis is perpendicular to Figure 4a The direction of the cross section line CD in . Figure 5 is an exploded view of the retractable wire device provided in this embodiment.

[0049] In order to improve the structural compactness of the telescopic line device, the first magnetic member 50 and the second magnetic member 60 can also be arranged relative to each other along the radial direction of the rotating component 20, so that the first magnetic member 50 and the second magnetic member 60 are adsorbed on the sides without the need to be stacked up and down, thereby reducing the overall height of the telescopic line device.

[0050] Specifically, if Figure 4a 、 Figure 4b as well as Figure 5 As shown, a protrusion 230 is provided on the rotating frame body 210, and a first magnetic member 50 is provided on the peripheral side of the protrusion 230; a groove 240 is provided on the lower base 120, and the protrusion 230 is accommodated in the groove 240, and the groove wall of the groove 240 is provided with the second magnetic member 60.

[0051] The protrusion 230 lifts the first magnetic member 50 toward the lower base 120, thereby reducing the distance between the first magnetic member 50 and the second magnetic member 60. Figure 4a 、 Figure 4b It can be seen that the protrusion 230 is accommodated in the groove 240 to facilitate the mutual adsorption between the second magnetic body and the first magnetic member 50 .

[0052] Specifically, the plurality of first magnetic members 50 may be arranged on the rotating assembly 20 at an annular circumferential interval, and correspondingly, the plurality of second magnetic members 60 may be arranged on the base 10 at an annular circumferential interval. Furthermore, in order to achieve uniform deceleration during the rotation of the rotating assembly 20 and avoid the winding speed being fast or slow, thereby affecting the user experience, the plurality of first magnetic members 50 may be arranged on the rotating assembly 20 at equal intervals, and correspondingly, the plurality of second magnetic members 60 may be arranged on the base 10 at equal intervals. Specifically, the first magnetic members 50 and the second magnetic members 60 may be cylindrical, rectangular, etc., and the base 10 and the rotating assembly 20 may be respectively provided with grooves. The first magnetic members 50 and the second magnetic members 60 may be fixed in the corresponding grooves by gluing, snapping, riveting, etc., which is not limited in the embodiment of the present application. The fixing method of the first magnetic member 50 and the second magnetic member 60 can ensure the stability of the installation of the first magnetic member 50 and the second magnetic member 60 without affecting the adsorption between them.

[0053] like Figure 5 as well as Figure 6 As shown, the rotating assembly 20 includes a rotating frame 210 and an elastic structure 70. The base 10 includes a connecting post 220, at least one end of which is fixedly connected to the base, or the connecting post 220 and the base are integrally formed. The connecting post 220 extends through the rotating frame 210. By fitting the rotating frame 210 over the connecting post 220, the rotating frame 210 is prevented from detaching from the base 10 during rotation, ensuring the usability of the retractable wire device.

[0054] The rotating frame 210 is rotatably connected to the outer periphery of the connecting column through the elastic structure 70. The data line 40 is wound around the outer side of the rotating frame 210 and one end is fixed to the rotating frame 210; the elastic structure 70 is used to reset the rotating frame 210. Figure 5 As shown, the elastic structure 70 may be a coil spring, etc. In combination with the rotational characteristics of the rotating assembly, in order to provide stronger take-up power and improve the take-up efficiency of the data cable 40, the elastic structure 70 is connected between the rotating frame 210 and the connecting post 220. The elastic force provided by the elastic structure 70 is used to reset the rotating frame 210, thereby increasing the take-up speed.

[0055] The retractable cable device provided in the embodiment of the present application includes a base 10 and a rotating assembly 20 disposed on the base 10. A data cable 40 is wound around the rotating assembly 20 and fixed at one end to the rotating assembly 20. The rotating assembly 20 drives the data cable 40 in and out of the base 10, thereby facilitating the storage and use of the data cable 40. Furthermore, a deceleration assembly 30 is provided on the rotating assembly 20 to provide resistance to the rotating assembly 20 during rotation, thereby preventing the data cable 40 from being retracted too quickly and affecting the user experience, thereby ensuring user safety. The embodiment of the present application can achieve a safe and convenient data cable 40 retractable experience.
