Detailed Implementation

[0068] The technical solution of this application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0069] In the embodiments described in this application, it should be noted that, unless otherwise stated and limited, the term "connection" should be interpreted broadly. For example, it can be an electrical connection, or a connection between two internal components. It can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above term according to the specific circumstances.

[0070] It should be noted that the terms "first," "second," and "third" used in the embodiments of this application are merely used to distinguish similar objects and do not represent a specific ordering of objects. It is understood that "first," "second," and "third" can be interchanged in a specific order or sequence where permitted. It should be understood that the objects distinguished by "first," "second," and "third" can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in an order other than those illustrated or described herein.

[0071] The following combination Figures 1 to 10 The present application provides a detailed description of the fully retractable cable reel, its circuitry, and its data cable assembly as described in the embodiments of this application.

[0072] Embodiment 1 describes a fully retractable cable reel, comprising: a housing 100, a winding member 200, and at least two first cables 310. The housing 100 has a receiving cavity 103 and at least one first opening 101 communicating with the receiving cavity 103. The winding member 200 is rotatably disposed within the receiving cavity 103. The at least two first cables 310 are wound side-by-side around the winding member 200; the first ends of the at least two first cables 310 are located outside the housing 100 through the at least one first opening 101.

[0073] In related technologies, data cable structures include a shell structure, a rotating structure, and a cable structure. The rotating structure enables the cable structure to be stretched and retracted. Some cables have multiple sub-cables at their ends, which extend outside the shell structure. This results in a larger volume of the data cable structure outside the shell structure in the retracted state, affecting the retraction efficiency. However, the fully retractable cable reel of this application allows at least two first cables 310 to be wound side-by-side around the winding member 200. This increases the volume of the at least two first cables 310 retracted within the shell 100 and reduces the volume of the at least two first cables 310 outside the shell 100. This reduces the volume of the fully retractable cable reel in the retracted state, thereby reducing its retracted volume and occupied storage space, and improving its retraction efficiency.

[0074] In this embodiment of the application, a fully retractable cable reel means that most of at least two first cables 310 can be retracted into the housing 100, which is more efficient than a data cable structure in which multiple sub-cables are located outside the housing structure. A fully retractable cable reel does not mean that all of the at least two first cables 310 are located inside the housing 100.

[0075] In the embodiments of this application, the structure of the housing 100 is not limited. For example, in some embodiments, the housing 100 can be a cuboid structure. In other embodiments, the housing 100 can be an elliptical structure.

[0076] As an example, such as Figure 8 As shown, the housing 100 may include a first half-shell 110 and a second half-shell 120, which are fixedly connected to the first half-shell 110 by means of a snap-fit ​​structure, a threaded structure, an adhesive structure, etc. Here, a first opening 101, a second opening 102, and a receiving cavity 103 may be defined between the second half-shell 120 and the first half-shell 110. Of course, in other examples, at least two first openings 101 may also be defined between the second half-shell 120 and the first half-shell 110.

[0077] The thickness of the housing 100 is not limited. For example, the thickness of the housing 100 may be less than twice the width of the first cable 310; here, the thickness direction of the housing 100 may be the same as or substantially the same as the axial direction of the winding member 200. The width of the first cable 310 may be the same as or substantially the same as the axial direction of the winding member 200. Of course, in other examples, the thickness of the housing 100 may also be greater than or equal to twice the width of the first cable 310.

[0078] In the embodiments of this application, the structure of the winding member 200 is not limited. For example, in some embodiments, the winding member 200 can be a columnar structure. In other embodiments, the winding member 200 can be a ring-shaped structure.

[0079] The implementation method in which the winding member 200 is rotatably disposed within the receiving cavity 103 is not limited. For example, in some embodiments, the winding member 200 can be rotatably disposed within the receiving cavity 103 via a rotating shaft structure. As an example, a connecting post 121 can be provided within the receiving cavity 103, and the winding member 200 can have a first connecting hole 201, with the connecting post 121 passing through and rotating within the first connecting hole 201; thereby, the winding member 200 is rotatably disposed within the receiving cavity 103 by the connecting post 121 passing through the first connecting hole 201. Here, as... Figure 8 As shown, the connecting post 121 can be fixed to the second half-shell 120. Alternatively, the connecting post 121 and the second half-shell 120 can be a single structural component; here, the connecting post 121 and the second half-shell 120 can be integrally molded by injection molding. The connecting post 121 can also be connected to the first half-shell 110, and the connecting post 121 and the first half-shell 110 can be connected by fasteners. The structure of the fasteners is not limited. For example, the fastener can be a screw. Alternatively, the connecting post 121 can also be fixed to the first half-shell 110, and the connecting post 121 and the first half-shell 110 can be a single structural component; here, the connecting post 121 and the first half-shell 110 can also be integrally molded by injection molding.

[0080] In this embodiment, the number of at least two first cables 310 is not limited. For example, as Figures 1 to 4 As shown, the number of at least two first cables 310 is two. The illustrations in this application mainly use the example of at least two first cables 310 being two. Of course, the number of at least two first cables 310 can be three, four, etc. This application does not limit this.

[0081] At least two first cables 310 are wound side-by-side on the winding member 200, wherein the at least two first cables 310 are wound on the winding member 200 in the same direction, such as... Figure 3As shown; here, at least two first cables 310 are similar to at least two sub-cables of a large cable.

[0082] The number of first openings 101 is not limited. The number of first openings 101 can be one or at least two. When the number of first openings 101 is one, the first ends of at least two first cables 310 can be located outside the housing 100 through the same first opening 101. When the number of first openings 101 is at least two, the first ends of at least two first cables 310 can also be located outside the housing 100 through different first openings 101; here, the number of first openings 101 and the number of first cables 310 can be the same.

[0083] like Figures 1 to 4 As shown, this application primarily illustrates an example where the first ends of at least two first cables 310 are located outside the housing 100 through the same first opening 101. Of course, the first ends of at least two first cables 310 may also be located outside the housing 100 through different first openings 101. Alternatively, portions of the first ends of at least three first cables 310 may be located outside the housing 100 through different first openings 101, while the remaining portions of the first ends of at least three first cables 310 may be located outside the housing 100 through the same first opening 101. This application does not impose any limitations on this.

[0084] When the first ends of at least two first cables 310 are located outside the housing 100 through the same first opening 101, the at least two first cables 310 can be more fully retracted into the housing 100 through the same first opening 101. This reduces the length of the ends of the at least two first cables 310 outside the housing 100 in the retracted state, thereby reducing the storage volume and storage space occupied by the fully retractable cable reel. At the same time, providing only one first opening 101 also simplifies the structure of the fully retractable cable reel.

[0085] In the embodiments of this application, the length of the cable can be increased by stretching one end or by stretching both ends.

[0086] For example, such as Figure 1 and Figure 2As shown, the housing 100 may also have a second opening 102 communicating with the receiving cavity 103; the fully retractable cable reel may also include: a second cable 320, which is used to be wound together with at least two first cables 310 on the winding member 200; a first end of the second cable 320 is located outside the housing 100 through the second opening 102; a second end 321 of the second cable 320 is electrically connected to the second ends 311 of at least two first cables 310; thereby, the cable length can be rapidly increased by stretching the second cable 320 and the at least two first cables 310 at both ends.

[0087] Here, as Figure 3 As shown, at least two first cables 310 are wound around the winding member 200 in the same direction; the second cable 320 is wound around the winding member 200 in the opposite direction to the first cables 310. When the second cable 320 is wound around the winding member 200 at least two times, at least two first cables 310 are located between two adjacent turns of the winding member 200.

[0088] For example, the fully retractable cable reel may also include a circuit board 520 and an interface component. The circuit board 520 may be attached to the winding component 200 by means of bonding, snap-fitting, etc., and is electrically connected to the second ends 311 of at least two first cables 310 respectively; the interface component may be attached to the housing 100 by means of bonding, snap-fitting, etc., and is electrically connected to the circuit board 520; the interface portion of the interface component is exposed through a third opening in the housing 100; thereby enabling the cable length to be increased by stretching at one end of at least two first cables 310.

[0089] Here, the interface portion of the interface component is used to connect the first electronic device, and the first ends of at least two first cables 310 are used to connect the second electronic device, thereby achieving an electrical connection between the first electronic device and the second electronic device through a fully retractable cable reel.

[0090] Here, the implementation method of electrically connecting the interface component and the circuit board 520 is not limited. For example, one of the interface component and the circuit board 520 is provided with at least one annular groove, and the other of the interface component and the circuit board 520 is provided with a conductive protrusion inserted into the annular groove, and a conductive part electrically connected to the conductive protrusion is provided in the annular groove. When the winding component 200 rotates relative to the housing 100, the conductive protrusion slides in the annular groove and is electrically connected to the conductive part.

[0091] The interface portion is a conductive structure. In one example, the interface portion can be electrically connected to a power supply device, and the first ends of at least two first cables 310 can be electrically connected to a power user device.

[0092] When the winding member 200 rotates relative to the housing 100, at least two first cables 310 extend outward from the housing 100 or retract into the housing 100 through the first opening 101 to adjust the distance between the first ends and the interface portions of the at least two first cables 310.

[0093] In some optional implementations of the embodiments of this application, the fully retractable cable reel may further include at least two first interface members 410. The at least two first interface members 410 are respectively connected to the first ends of at least two first cables 310, so that the first ends of the at least two first cables 310 are electrically connected to electronic devices through the at least two first interface members 410.

[0094] In this implementation, at least two first interface devices 410 can be of the same type, so that the first ends of at least two first cables 310 can be simultaneously connected to electronic devices with the same interface type. For example, the first interface device 410 can be a Micro-USB connector, a Lightning connector, or a USB Type-C connector.

[0095] Of course, the at least two first interface devices 410 can be of different types, so that the first ends of the at least two first cables 310 can simultaneously connect to electronic devices with different interface types. For example, the first interface device 410 can be at least two or three of the following: Micro USB interface, Lightning interface, and USB Type-C interface.

[0096] In this implementation, the first interface member 410 is used to lock into the first opening 101 in the storage state, thereby preventing the first end of the first cable 310 from entering the housing 100 and allowing most of the first cable 310 to be located inside the housing 100 in the storage state. Here, the first interface member 410 can wrap around the first end of the first cable 310, so that in the storage state, the first interface member 410 is exposed and the first cable 310 is hidden, thereby protecting the first cable 310 in the storage state and preventing the first cable 310 from being damaged by external objects.

[0097] Here, the shape and size of the first interface 410 and the first opening 101 are not limited, as long as the first interface 410 can be snapped into the first opening 101.

[0098] For example, the width of the first interface component 410 can be greater than the width of the first opening 101. Another example is that the height of the first interface component 410 can be greater than the height of the first opening 101. Yet another example is that the cross-sectional dimension of the first interface component 410 can be greater than the cross-sectional dimension of the first opening 101.

[0099] In this implementation, at least two adjacent first interface components 410 can be connected by magnetic attraction, so that the two first interface components 410 are connected and occupy less space, thereby reducing the storage space of the full-capacity cable reel.

[0100] Here, the method by which two adjacent first interface pieces 410 are connected by magnetic attraction is not limited. For example, both adjacent first interface pieces 410 may be provided with magnetic structures, and the polarities of the magnetic structures may be opposite to achieve connection by magnetic attraction. As another example, one of the two adjacent first interface pieces 410 may be provided with a magnetic structure, and the other with an iron structure.

[0101] In some optional implementations of the embodiments of this application, the housing 100 may further have a second opening 102 communicating with the receiving cavity 103; the fully retractable cable reel may further include a second cable 320. The second cable 320 is used to be wound together with at least two first cables 310 on the winding member 200; the first end of the second cable 320 is located outside the housing 100 through the second opening 102; the second end 321 of the second cable 320 is electrically connected to the second ends 311 of at least two first cables 310; thereby, the cable length can be rapidly increased by stretching the second cable 320 and at least two first cables 310 at both ends.

[0102] In this implementation, the second end 321 of the second cable 320 can be directly connected to the second ends 311 of at least two first cables 310, so that one of the first cables 310 can be electrically connected to the second cable 320.

[0103] Here, during use, at least two first cables 310 that are first connected to the electronic device can be electrically connected to the second cable 320. At least two first cables 310 that are subsequently connected to the electronic device cannot be electrically connected to the second cable 320. For example, if the second cable 320 is connected to a power supply device, the first cable 310 that is first connected to the power-consuming device among the at least two first cables 310 can be electrically connected to the second cable 320 to enable the power supply device to supply power to the power-consuming device.

[0104] Here, when the fully retractable cable reel includes at least two first interface pieces 410, the types of the at least two first interface pieces 410 can be different, so that the fully retractable cable reel can provide different types of first interfaces, thereby improving the adaptability of the fully retractable cable reel. Of course, the types of the at least two first interface pieces 410 can also be the same, so that if one first interface piece 410 is damaged, it can still work through the other first interface piece 410, thereby improving the service life of the fully retractable cable reel.

[0105] In this implementation, the fully retractable cable reel may further include a circuit board 520 and a functional component 730. The circuit board 520 may be attached to the winding member 200 by means of adhesive bonding, snap-fitting, etc.; the second end 321 of the second cable 320 is connected to the second ends 311 of at least two first cables 310 respectively through the circuit board 520; the functional component 730 may be disposed on the circuit board, and the functional component 730 is used to enable at least two first cables 310 and the second cable 320 to be electrically connected and work simultaneously; thereby enabling at least two electronic devices to work simultaneously through at least two first cables 310.

[0106] As an example, when the second cable 320 is electrically connected to the power supply equipment, at least two first cables 310 can be electrically connected to the power supply equipment at the same time, thereby enabling the simultaneous supply of power to multiple power supply equipment through at least two first cables 310, circuit boards and functional components 730.

[0107] Here, the implementation method in which the second end 321 of the second cable 320 is connected to the second ends 311 of at least two first cables 310 via the circuit board 520 is not limited.

[0108] For example, the second end 321 of the second cable 320 can be directly connected to the circuit board 520 by soldering or bonding. Of course, as... Figure 4 As shown, the second end 321 of the second cable 320 can also be connected to the circuit board 520 through the second wiring group 5421; here, the second wiring group 5421 is connected to the second end 321 of the second cable 320 and the circuit board 520 respectively.

[0109] For example, the second ends 311 of at least two first cables 310 can be directly connected to the circuit board 520 by soldering or bonding. Of course, as... Figure 4As shown, the second ends 311 of at least two first cables 310 can also be connected to the circuit board 520 through at least two first wiring groups 541; here, at least two first wiring groups 541 are respectively connected to the second ends 311 of at least two first cables 310 and the circuit board 520; here, the number of at least two first wiring groups 541 can be the same as the number of at least two first cables 310, so that each first wiring group 541 is respectively connected to the second end 311 of a first cable 310 and the circuit board 520.

[0110] In this implementation, the structure of the functional component 730 is not limited, as long as the functional component 730 can enable at least two first cables 310 and second cables 320 to be electrically connected and work simultaneously.

[0111] For example, functional component 730 may include a distribution circuit and a controller. The distribution circuit is disposed on a circuit board. The distribution circuit is electrically connected to the second cable 320 and at least two first cables 310, respectively. The controller is disposed on the circuit board and is used to control the operation of the distribution circuit so that the second cable 320 can be electrically connected to at least two first cables 310 simultaneously. The distribution circuit and controller enable current at the second cable 320 to flow simultaneously to at least two first cables 310, thereby enabling at least two first cables 310 to operate simultaneously.

[0112] Of course, in this implementation, the fully retractable cable reel may only include the circuit board 520 and not the functional component 730. Here, the circuit board 520 is only used to electrically connect the second ends 311 of at least two first cables 310 and the second ends 321 of the second cable 320.

[0113] The shape of circuit board 520 is not limited. For example, as shown... Figure 4 and Figure 7 As shown, the circuit board 520 can be a ring-shaped structure, and the winding member 200 is rotatably connected to the housing 100 through the through hole 521 defined by the circuit board 520. The ring-shaped structure of the circuit board 520 enables the winding member 200 to be subjected to more balanced forces in the circumferential direction, thereby making the rotation of the winding member 200 smoother. Of course, in other examples, the circuit board 520 can also be a semi-ring-shaped structure or a rectangular structure.

[0114] In this implementation, the fully retractable cable reel may further include a second interface 420, which is connected to the first end of the second cable 320.

[0115] In this implementation, the type of the second interface device 420 is not limited. For example, the second interface device 420 can be one of a Micro USB interface, a Lightning interface, or a USB Type-C interface.

[0116] In this implementation, the second interface member 420 can be used to lock into the second opening 102 in the retracted state, thereby preventing the first end of the second cable 320 from entering the housing 100; and in the retracted state, most of the second cable 320 is located inside the housing 100. Here, the second interface member 420 can wrap around the first end of the second cable 320, so that in the retracted state, the second interface member 420 is exposed and the second cable 320 is hidden, thereby protecting the second cable 320 in the retracted state and preventing the second cable 320 from being damaged by external objects.

[0117] Here, the shape and size of the second interface 420 and the second opening 102 are not limited, as long as the second interface 420 can be snapped into the second opening 102.

[0118] For example, the width of the second interface component 420 can be greater than the width of the second opening 102. As another example, the height of the second interface component 420 can be greater than the height of the second opening 102. Yet another example, the cross-sectional dimension of the second interface component 420 can be greater than the cross-sectional dimension of the second opening 102.

[0119] In this implementation, a storage slot may be provided on the outer side of the housing 100 to accommodate the first interface component 410 and / or the second interface component 420. Here, the storage slot may be used only to accommodate the first interface component 410, or only to accommodate the second interface component 420, or to accommodate both the first interface component 410 and the second interface component 420 simultaneously.

[0120] In some optional implementations of the embodiments of this application, such as Figure 3As shown, the winding member 200 may include: a first cylindrical portion 210 and a second cylindrical portion 220. The first cylindrical portion 210 is circumferentially closed; the second cylindrical portion 220 is radially located outside the first cylindrical portion 210 of the winding member 200 and defines a mounting space 202 with the first cylindrical portion 210; the second cylindrical portion 220 has at least one first through groove 221 communicating with the mounting space 202; at least two first cables 310 are wound around the second cylindrical portion 220; the second ends 311 of the at least two first cables 310 pass through the first through groove 221 and are located within the mounting space 202; an elastic member 530 is disposed within the cavity defined by the first cylindrical portion 210 and is respectively connected to the winding member 200 and the housing 100. The connection; the elastic member 530 is used to provide a restoring force to the winding member 200 to rotate in the storage direction; thereby, the winding member 200 can be automatically rotated in the storage direction by the elastic member 530; at the same time, the elastic member 530 is disposed in the cavity defined by the first cylindrical portion 210, and the first cylindrical portion 210 is closed in the circumferential direction; the first cylindrical portion 210 can completely separate at least one first cable 310 from the elastic member 530, preventing the first cable 310 from contacting the elastic member 530, thereby preventing the elastic member 530 from causing wear to the first cable 310, and thus improving the service life of the first cable 310.

[0121] In this implementation, the structure of the elastic element 530 is not limited. For example, the elastic element 530 may be coiled within the cavity defined by the first cylindrical portion 210; the elastic element 530 may be a coil spring.

[0122] The elastic element 530 and the winding element 200 can be connected by means of bonding, snap-fitting, welding, etc. The elastic element 530 and the housing 100 can be connected by means of bonding, snap-fitting, welding, etc.

[0123] As an example, such as Figure 3 and 5 As shown, the winding member 200 may further include: a retaining wall 250 located within the cavity defined by the first cylindrical portion 210; an elastic member 530 coiled within the cavity defined by the first cylindrical portion 210; the first end of the elastic member 530 being connected to the housing 100 by means of bonding, snapping, welding, etc.; and the second end of the elastic member 530 being connected to the retaining wall 250 by means of bonding, snapping, welding, etc. Here, the first end of the elastic member 530 may be connected to the connecting post 121.

[0124] In this implementation, such as Figure 5 and Figure 6As shown, the winding member 200 may further include: a first plate portion 230 and a second plate portion 240. The first plate portion 230 may be connected to the first end of the first cylindrical portion 210 and the first end of the second cylindrical portion 220, respectively; the second plate portion 240 may be connected to the second end of the first cylindrical portion 210 and the second end of the second cylindrical portion 220, respectively; the second plate portion 240 has an installation slot 243; the elastic member 530 is installed in the cavity defined by the first cylindrical portion 210 through the installation slot 243; the fully retractable winding device may further include: a positioning member 510, which covers the installation slot 243; the positioning member 510 is used to limit the rotational position of the winding member 200 relative to the housing 100, thereby limiting the rotational position of the winding member 200 relative to the housing 100 and blocking the installation slot 243, greatly simplifying the structure of the fully retractable winding device.

[0125] Here, the structure of the positioning element 510 is not limited. For example, the positioning element 510 can be a plate-like structure.

[0126] Positioning element 510 can be positioned by its surface or by its groove.

[0127] Here, as Figure 6 As shown, the positioning member 510 may have a second connecting hole 516. The second connecting hole 516 and the first connecting hole 201 may be coaxially arranged. The first connecting hole 201 may be located in the first plate portion 230. The connecting post 211 may pass through the first connecting hole 201 and the second connecting hole 516.

[0128] In some optional implementations of the embodiments of this application, the fully retractable cable reel may further include: a positioning member 510, which may be disposed on the winding member 200 by means of adhesive, snap-fit ​​or other means, and is used to limit the rotational position of the winding member 200 relative to the housing 100; thereby, the positioning member 510 can make the winding member 200 no longer rotate relative to the housing 100, so that at least two first cables 310 maintain a suitable length.

[0129] In this implementation, the structure of the positioning member 510 is not limited. The location of the positioning member 510 is also not limited. For example, the positioning member 510 can be located on the periphery of the winding member 200 or on the end side of the winding member 200. Alternatively, the positioning member 510 can prevent the winding member 200 from rotating relative to the housing 100 through surface contact or through a groove engagement.

[0130] For example, when the full-capacity reel includes a circuit board 520, the positioning member 510 and the circuit board 520 can be located on opposite sides of the winding member 200 in the axial direction of the winding member 200, so that the positioning member 510 and the circuit board 520 do not affect each other.

[0131] The circuit board 520 here can be a circuit board that is connected to the second end 321 of the second cable 320 and the second end 311 of at least two first cables 310 respectively, or it can be a circuit board that is electrically connected to the second end 311 of at least two first cables 310 and the interface device respectively.

[0132] As an example, such as Figure 6 As shown, the positioning member 510 may include: an inner annular slide 511, an outer annular slide 512, a sliding in channel 513, a sliding out channel 514, and a slot 515. The inner annular slide 511 is formed on the end face of the positioning member 510; the outer annular slide 512 is formed on the end face of the positioning member 510 and is radially spaced from the inner annular slide 511 on the winding member 200; the sliding in channel 513 is formed on the end face of the positioning member 510 and communicates with both the inner annular slide 511 and the outer annular slide 512; the sliding out channel 514 is formed on the end face of the positioning member 510 and communicates with both the inner annular slide 511 and the outer annular slide 512; the slot 515 is formed at the sliding in channel 513; the fully retractable winding device may also include: a limiting member 550, such as... Figure 8 As shown, the limiting member 550 can be rotatably disposed on the housing 100 via a rotating shaft structure; the limiting member 550 has a limiting protrusion 551 facing the winding member 200, the limiting protrusion 551 is used to cooperate with the slot 515 to limit the rotational position of the winding member 200 relative to the housing 100.

[0133] Here, the limiting protrusion 551 can slide within the inner annular slide 511, the outer annular slide 512, the sliding in channel 513, and the sliding out channel 514. When the limiting protrusion 551 slides to engage with the slot 515, the winding member 200 no longer rotates, thereby enabling the first cable 310 to be at a suitable pull-out length.

[0134] During use, when the first cable 310 is stretched by external force, the limiting protrusion 551 slides in the outer annular slide 512. When the first cable 310 is stretched to a suitable length, the external force is removed, and the winding member 200 rotates in the opposite direction under the action of the elastic member 530. The limiting protrusion 551 enters the slot 515 from the sliding in channel 513, and the winding member 200 stops rotating. When the winding member 200 is gently pulled and released, the limiting protrusion 551 enters the inner annular slide 511 from the sliding in channel 513 and rotates in the opposite direction under the action of the elastic member 530. The limiting protrusion 551 slides in the inner annular slide 511 until the first cable 310 is fully retracted. The ability of the limiting protrusion 551 to slide within the inner annular slide 511, outer annular slide 512, sliding in channel 513, and sliding out channel 514 ensures that there is no loud noise during the stretching or retraction of the first cable 310.

[0135] Example 2: This application also describes a fully retractable cable reel, comprising: a housing 100, a winding member 200, at least two first cables 310, and a circuit board 520. The housing 100 has a receiving cavity 103 and at least one first opening 101 communicating with the receiving cavity 103; the winding member 200 is rotatably disposed within the receiving cavity 103; at least two first cables 310 are used to be wound side-by-side around the winding member 200; the first ends of the at least two first cables 310 are located outside the housing 100 through at least one first opening 101; the circuit board 520 is disposed on the winding member 200 and electrically connected to the second ends 311 of the at least two first cables 310 respectively.

[0136] In related technologies, data cable structures include a shell structure, a rotating structure, and a cable structure. The rotating structure enables the cable structure to be stretched and retracted. Some cables have multiple sub-cables and circuit structures at their ends, located outside the shell structure. This results in a larger volume of the data cable structure outside the shell structure in the retracted state, affecting the retraction efficiency. However, the fully retractable cable reel of this application has a circuit board 520 located within the housing 100 and housed within the winding member 200. This reduces the volume of the fully retractable cable reel in the retracted state, thereby reducing its retracted volume and occupied storage space, and improving its retraction efficiency.

[0137] The above embodiment 1 has already described the housing 100, the winding component 200, at least two first cables 310 and the circuit board 520, and will not be repeated here.

[0138] In some optional implementations of the embodiments of this application, the housing 100 may also have a second opening 102 communicating with the receiving cavity 103; the fully retractable cable reel may also include: a second cable 320, which is used to be wound together with at least two first cables 310 on the winding member 200; the first end of the second cable 320 is located outside the housing 100 through the second opening 102; the second end 321 of the second cable 320 is electrically connected to the circuit board 520; thereby enabling the fully retractable cable reel to quickly adjust the length of the cable.

[0139] In this implementation, such as Figure 4As shown, the fully retractable cable reel may further include at least two first wiring groups 541 and a second wiring group 5421. The at least two first wiring groups 541 can be electrically connected to different areas of the circuit board and the second ends of at least two first cables 310, respectively; the second wiring group 5421 can be electrically connected to the circuit board and the second ends 321 of the second cables 320, respectively. The at least two first wiring groups 541 reduce the space occupied by the connection area between the second ends of the at least two first cables 310 and the circuit board, and the second wiring group 5421 reduces the space occupied by the connection area between the second ends 321 of the second cables 320 and the circuit board.

[0140] Here, the first wiring group 541 may include at least two first single wires, which are electrically connected to different areas of the circuit board and the second end of the first cable 310, respectively. The cross-sectional size of each first single wire is small, and the at least two first single wires are not connected to each other, thereby reducing the installation space of the at least two first single wires and ensuring that the at least two first single wires do not affect each other, making the connection of the single first single wires more flexible.

[0141] Here, the second wiring group 5421 may include at least two second single wires, which are electrically connected to the second end of the circuit board and the second cable 320, respectively. The cross-sectional size of each second single wire is small, and the at least two second single wires are not connected to each other, thereby reducing the installation space of the at least two second single wires and ensuring that the at least two second single wires do not affect each other, making the connection of the single second single wires more flexible.

[0142] In some optional implementations of the embodiments of this application, the fully retractable cable reel may further include an interface component, which may be disposed on the housing 100 by means of bonding, snap-fitting, welding, etc., and electrically connected to the circuit board 520; the interface portion of the interface component is exposed through the third opening of the housing 100; thereby realizing the adjustment of the cable length by at least two first cables 310.

[0143] The above embodiments have described the implementation of the electrical connection between the interface device and the circuit board 520, and will not be repeated here.

[0144] In some optional implementations of the embodiments of this application, such as Figure 9As shown, the fully retractable cable reel may further include: at least two first interface portions 710 and a second interface portion 720. The at least two first interface portions 710 may be disposed in different areas of the circuit board by means of bonding, soldering, etc., and are respectively electrically connected to the second ends 311 of at least two first cables 310; the second interface portions 720 may be disposed on the circuit board by means of bonding, soldering, etc.; a functional component 730 is disposed on the circuit board; the functional component 730 is used to enable the at least two first cables 310 to be electrically connected to the second interface portion 720 simultaneously. Thus, the functional component 730 and the circuit board enable the at least two first cables 310 to work simultaneously.

[0145] Of course, in other implementations, the fully retractable cable reel may also exclude the functional component 730, where the circuit board is used for conductive connections.

[0146] In this implementation, at least two first interface portions 710 can be directly electrically connected to the second ends 311 of at least two first cables 310, or they can be electrically connected to the second ends 311 of at least two first wiring groups 541.

[0147] In this implementation, the second interface 720 can be directly electrically connected to the second end 311 of the second cable 320, or it can be electrically connected to the second end 311 of the second cable 320 through the second wiring group 5421, or it can be electrically connected to the interface component.

[0148] In some optional implementations of the embodiments of this application, the fully retractable cable reel may further include: a positioning member 510, which can be disposed on the winding member 200 by means of adhesive, snap-fit, etc., and is used to limit the rotational position of the winding member 200 relative to the housing 100; the positioning member 510 and the circuit board 520 can be located on opposite sides of the winding member 200 in the axial direction of the winding member 200. Thus, the positioning member 510 can prevent the winding member 200 from rotating relative to the housing 100, and the positioning member 510 and the circuit board 520 can be prevented from interfering with each other.

[0149] The positioning element 510 has been described in the above embodiments and will not be repeated here.

[0150] In some optional implementations of the embodiments of this application, such as Figure 3As shown, the winding member 200 may include: a first cylindrical portion 210 and a second cylindrical portion 220. The first cylindrical portion 210 is circumferentially closed; the second cylindrical portion 220 is radially located outside the first cylindrical portion 210 of the winding member 200 and defines an installation space 202 with the first cylindrical portion 210; the second cylindrical portion 220 has at least one first through groove 221 communicating with the installation space 202; at least two first cables 310 are used to be wound around the second cylindrical portion 220; the second ends 311 of the at least two first cables 310 pass through the first through groove 221 and are located within the installation space 202; the fully retractable winding member may further include: an elastic member 530, the elastic member 530 being disposed within the cavity defined by the first cylindrical portion 210 and respectively connected to the winding member. The member 200 is connected to the housing 100; the elastic member 530 is used to provide a restoring force to the winding member 200 to rotate in the storage direction; thereby, the winding member 200 can be automatically rotated in the storage direction by the elastic member 530; at the same time, the elastic member 530 is disposed in the cavity defined by the first cylindrical portion 210, and the first cylindrical portion 210 is closed in the circumferential direction; the first cylindrical portion 210 can completely separate at least one first cable 310 from the elastic member 530, preventing the first cable 310 from contacting the elastic member 530, thereby preventing the elastic member 530 from causing wear to the first cable 310, and thus improving the service life of the first cable 310.

[0151] The elastic element 530 has been described in the above embodiments and will not be repeated here.

[0152] In some optional implementations of the embodiments of this application, the fully retractable cable reel may further include at least two first interface pieces 410, and the at least two first interface pieces 410 are respectively connected to the first ends of at least two first cables 310.

[0153] In this implementation, the first interface component 410 can be used to be locked at the first opening 101 in the storage state.

[0154] In this implementation, at least two first interface components 410 can be of the same type or different types.

[0155] The first interface 410 has been described in the above embodiments and will not be repeated here.

[0156] Example 3, as Figure 9As shown in the embodiments of this application, a circuit device for a fully retractable cable reel is also described, including: a circuit board, at least two first interface portions 710, a second interface portion 720, and a functional component 730. The circuit board may have a positioning structure that cooperates with the winding member 200 of the fully retractable cable reel; the at least two first interface portions 710 may be disposed in different areas of the circuit board by means of bonding, welding, etc.; the second interface portion 720 may be disposed on the circuit board by means of bonding, welding, etc.; the functional component 730 is disposed on the circuit board; the functional component 730 is used to enable the at least two first interface portions 710 and the second interface portion 720 to be electrically connected and work simultaneously; thereby enabling the at least two first interface portions to work simultaneously.

[0157] This application also describes a fully retractable cable reel, comprising: a circuit device according to this application embodiment, a housing 100, a winding member 200, and at least two first cables 310. The housing 100 has a receiving cavity 103 and at least one first opening 101 communicating with the receiving cavity 103; the winding member 200 is rotatably disposed within the receiving cavity 103; a circuit board 520 is disposed on the winding member 200 by means of adhesive bonding, snap-fitting, etc.; at least two first cables 310 are used to be wound side by side on the winding member 200; the first ends of the at least two first cables 310 are located outside the housing 100 through at least one first opening 101; the second ends 311 of the at least two first cables 310 are respectively electrically connected to at least two first interface portions 710.

[0158] In related technologies, data cable structures include a shell structure, a rotating structure, and a cable structure. The rotating structure enables the cable structure to be stretched and retracted. Some cables have multiple sub-cables and circuit structures at their ends, located outside the shell structure. This results in a larger volume of the data cable structure outside the shell structure in the retracted state, affecting the retraction efficiency. However, the circuit board 520 of the fully retractable cable reel in this application, through a positioning structure, can be positioned within the shell 100 and mounted on the winding member 200. This reduces the volume of the fully retractable cable reel in the retracted state, thereby reducing its retracted volume and the space it occupies, and improving its retraction efficiency.

[0159] The above embodiments have already described the housing 100, the winding member 200, and at least two first cables 310, which will not be repeated here.

[0160] In the embodiments of this application, the structure of the circuit board is not limited. For example, as shown... Figure 9 and Figure 10As shown, the circuit board 520 can be a ring-shaped structure so that the winding member 200 can be rotatably connected to the housing 100 through the through hole 521 defined by the circuit board 520. At the same time, the ring-shaped structure of the circuit board 520 can also increase the space available for the functional components 730. Alternatively, the circuit board 520 can also be a rectangular structure, a semi-ring-shaped structure, etc.

[0161] The form of the positioning structure is not limited, as long as the circuit board is fixed relative to the winding component 200 by the positioning structure. For example, Figure 9 As shown, the positioning structure may include a through hole 521 defined by the circuit board 520, thereby enabling the circuit board 520 to be positioned on the winding member 200 through the through hole 521; here, as Figure 7 As shown, part of the winding component 200 can be inserted into the through hole 521 to achieve the positioning of the circuit board.

[0162] For example, such as Figure 9 As shown, the positioning structure may include positioning holes 522 formed in the circuit board, through which the circuit board 520 can be positioned on the winding member 200; here, as Figure 7 As shown, the positioning protrusions 203 of the winding member 200 can be inserted into the positioning holes 522. The number of positioning holes 522 is not limited. For example, there can be four positioning holes 522, and the arrangement of the four positioning holes 522 is not limited. As an example, the four positioning holes 522 can be spaced apart circumferentially along the circuit board; similarly, the positioning protrusions 203 can also be spaced apart circumferentially along the winding member 200.

[0163] Of course, the positioning structure may include both the through hole 521 defined by the circuit board 520 and the positioning hole 522 opened on the circuit board.

[0164] In this embodiment, the first interface portion 710 is a conductive structure. For example, the material of the first interface portion 710 can be copper, aluminum, etc. The first interface portion 710 can be a block structure or a columnar structure, etc. The first interface portion 710 is electrically connected to the conductive layer in the circuit board.

[0165] The number of at least two first interface sections 710 is not limited. For example, such as Figure 9 As shown, there are at least two first interface portions 710, which are electrically connected to the second ends of the two first cables 310 respectively.

[0166] In this embodiment, the second interface portion 720 is a conductive structure. For example, the material of the second interface portion 720 can be copper, aluminum, etc. The second interface portion 720 can be a block structure or a columnar structure, etc. The second interface portion 720 is electrically connected to the conductive layer in the circuit board.

[0167] At least two first interface portions 710 and second interface portions 720 can be disposed on the same side of the circuit board, such as... Figure 9 As shown, this makes the circuit arrangement neater. Of course, at least two first interface portions 710 and a second interface portion 720 can also be provided on different sides of the circuit board.

[0168] In the embodiments of this application, the functional component 730 may include conductive circuits disposed in a circuit board, or electronic components disposed on the circuit board.

[0169] The location of functional component 730 is not limited. For example... Figure 9 As shown, at least two first interface portions 710, second interface portions 720, and functional components 730 protruding from the circuit board surface can be disposed on the same side of the circuit board, such as... Figure 9 As shown, this is to make the circuit arrangement neater; here, the portion of the functional component 730 protruding from the circuit board surface can be an electronic component on the circuit board. Of course, at least two first interface portions 710, second interface portions 720, and the portion of the functional component 730 protruding from the circuit board surface can also be located on different sides of the circuit board. As an example, at least two first interface portions 710 and second interface portions 720 can be located on one side of the circuit board, and the portion of the functional component 730 protruding from the circuit board surface can be located on the other side of the circuit board. As yet another example, at least two first interface portions 710 and the portion of the functional component 730 protruding from the circuit board surface can be located on one side of the circuit board, and the second interface portion 720 can be located on the other side of the circuit board.

For example, the functional component 730 may include a MOS MOSFET and a DC-DC converter, and the second interface section 720 can be electrically connected to at least two first interface sections 710 through the MOS transistor and the DC-DC converter, so that at least two first interface sections 710 can operate simultaneously.

[0171] In some optional implementations of the embodiments of this application, the circuit device may further include: at least two first wiring groups 541 and a connection group 542.

[0172] Of course, in other implementations, the circuit arrangement may not include at least one of the two first wiring groups 541 and connection groups 542.

[0173] The first wiring group 541 has been described in the above embodiments and will not be repeated here.

[0174] In this implementation, the structure of the connection group 542 is not limited. For example, the connection group 542 may include a second wiring group 5421, through which the second interface portion 720 can be more flexibly electrically connected to other structures. The second wiring group 5421 has been described in the above embodiments and will not be repeated here.

[0175] For example, the connection group 542 can protrude from the surface of the circuit board. Here, the connection group 542 can be an elastic conductive structure or a rigid conductive structure. As another example, the connection group 542 can be disposed within the first annular groove of the circuit board. Here, the connection group 542 can be an elastic conductive structure or a rigid conductive structure.

[0176] In some optional implementations of the embodiments of this application, the functional component 730 may include: a distribution circuit and a controller. The distribution circuit may be disposed on a circuit board; the distribution circuit is electrically connected to the second interface portion 720 and at least two first interface portions 710 respectively; the controller may be disposed on the circuit board, and the controller is used to control the operation of the distribution circuit so that the second interface portion 720 can be electrically connected to at least two first interface portions 710 simultaneously, thereby enabling at least two first interface portions 710 to operate simultaneously.

[0177] In this implementation, the distribution circuit can be disposed within the conductive layer of the circuit board. The distribution circuit may include a main circuit and at least two branches; the first end of the main circuit may be electrically connected to the second interface portion 720; the at least two branches may be arranged in parallel; the first ends of the at least two branches are electrically connected to the second end of the main circuit; the second ends of the at least two branches are respectively electrically connected to at least two first interface portions 710; the number of at least two branches may be the same as the number of at least two first interface portions 710, so that the second interface portion 720 can be electrically connected to the at least two first interface portions 710 through the at least two branches; here, each branch is electrically connected to the second interface portion 720 and one first interface portion 710 respectively.

[0178] In this implementation, the controller can be electrically connected to at least two first interface sections 710. The controller can obtain the state that at least two first interface sections 710 are connected to electronic devices. When at least two first interface sections 710 are connected to electronic devices, the controller can control the current through at least two branches, thereby enabling at least two first interface sections 710 to operate simultaneously.

[0179] In this implementation, the functional component 730 may further include: at least two switches, which may be respectively disposed on at least two branches, wherein each branch may have one switch; and a controller that can be used to control the at least two switches to be turned on or off. Thus, the controller can flexibly control the at least two branches to be turned on or off, thereby controlling the connection and disconnection between the second interface section 720 and at least two first interface sections 710.

[0180] Here, the number of at least two switches can be the same as the number of at least two first interface sections 710.

[0181] In some optional implementations of the embodiments of this application, the functional component 730 may further include: an adapter circuit, which may be disposed between at least two first interface portions 710 and a second interface portion 720; when one of the first interface portions 710 is connected to an electrical device, the controller is used to control the second interface portion 720 to be electrically connected to the first interface portion 710 through the adapter circuit; thereby adapting the performance of the electrical device through the adapter circuit.

[0182] In this implementation, the adapter circuit can be located inside the circuit board.

[0183] In this implementation, the adapter circuit differs from the distribution circuit; the adapter circuit can adapt to the performance of the power-consuming device. As an example, when at least two first interface sections 710 operate simultaneously, the controller can control at least two first interface sections 710 to use the same charging PD protocol. When only one first interface section 710 is operating, that first interface section 710 can use the power-consuming device's proprietary charging protocol through the adapter circuit, thereby improving the charging efficiency of the power-consuming device.

[0184] The controller is not limited in the manner in which the second interface section 720 is electrically connected to the first interface section 710 via the adapter circuit. For example, the functional component 730 may further include: a switch disposed in the adapter circuit; when at least two first interface sections 710 are connected to a power device, the controller controls the switch to be in the position that disconnects the adapter circuit, where at least two first interface sections 710 are electrically connected to the second interface section 720 via a distribution circuit; when one of the at least two first interface sections 710 is connected to a power device, the controller controls the switch to be in the position that the second interface section 720 is electrically connected to the first interface section 710 via the adapter circuit, thereby adapting the power device of the first interface section 710.

[0185] The specific form of the switch is not limited here. For example, the switch can be an analog switch.

[0186] In some optional implementations of the embodiments of this application, the functional component 730 may further include: a voltage regulator component, which may be disposed between the second interface section 720 and the controller; the voltage regulator component is used to adjust the power supply voltage provided by the second interface section 720 to the controller, so that the second interface section 720 and the voltage regulator component can provide a stable and suitable voltage to the controller.

[0187] In this implementation, the structure of the voltage regulator is not limited. For example, the voltage regulator may include a low-dropout regulator (LDO).

[0188] In this implementation, the operating voltage of the controller is not limited. For example, the operating voltage of the controller can be 5 volts. The supply voltage of the second interface section 720 is also not limited. For example, the supply voltage of the second interface section 720 can be 20 volts. Here, the voltage regulator can adjust the 20 volts provided by the second interface section 720 to 5 volts for the controller to use, thereby ensuring the power supply safety of the controller; at the same time, the voltage regulator can also keep the voltage provided by the second interface section 720 to the controller at 5 volts to ensure the stability of the controller's power supply.

[0189] In some optional implementations of the embodiments of this application, the housing 100 may also have a second opening 102 communicating with the receiving cavity 103; the fully retractable cable reel may also include: a second cable 320, the second cable 320 being wound together with at least two first cables 310 on the winding member 200; the first end of the second cable 320 being located outside the housing 100 through the second opening 102; the second end 321 of the second cable 320 being electrically connected to the second interface portion 720, thereby enabling the fully retractable cable reel to quickly adjust the length of the cable by double-end stretching.

[0190] The second cable 320 has been described in the above embodiments and will not be repeated here.

[0191] In some optional implementations of the embodiments of this application, the fully retractable cable reel may further include an interface component. The interface component may be disposed on the housing 100 by means of adhesive bonding, snap-fitting, etc., and electrically connected to the second interface portion 720. The interface portion of the interface component is exposed through the third opening of the housing 100, thereby enabling the fully retractable cable reel to adjust the length of the cable by single-end stretching.

[0192] In this implementation, the manner in which the interface component is electrically connected to the second interface section 720 is not limited. For example, the interface component and the second interface section 720 are electrically connected via a connection assembly 542.

[0193] As an example, the connection group 542 can be disposed in the first annular groove of the circuit board, and the interface component has a conductive protrusion that is inserted into the first annular groove and electrically connected to the interface portion of the connection group 542 and the interface component, respectively.

[0194] As another example, the connection group 542 may protrude from the surface of the circuit board, and the interface component may have a second annular groove; the connection group 542 is inserted into the second annular groove and is electrically connected to the interface portion of the interface component.

[0195] Embodiment 4 further describes a data cable device, including: a housing 100, a winding member 200, at least one first cable 310, and an elastic member 530. The housing 100 has a receiving cavity 103 and a first opening 101 communicating with the receiving cavity 103; the winding member 200 is rotatably disposed within the receiving cavity 103; the winding member 200 may include: a first cylindrical portion 210 and a second cylindrical portion 220. The first cylindrical portion 210 is circumferentially closed; the second cylindrical portion 220 is located radially outside the first cylindrical portion 210 of the winding member 200 and defines an installation space 202 with the first cylindrical portion 210; the second cylindrical portion 220 has at least one first through groove 221 communicating with the installation space 202; at least one first cable 310 is wound around the second cylindrical portion 220; the first end of at least one first cable 310 passes through the first opening 101 and is located outside the housing 100, and the second end 311 of at least one first cable 310 passes through the first through groove 221 and is located inside the installation space 202; the elastic member 530 is disposed in the cavity defined by the first cylindrical portion 210 and is connected to the winding member 200 and the housing 100 respectively; the elastic member 530 is used to provide a restoring force to the winding member 200 for rotation in the storage direction.

[0196] In related technologies, data cable structures include a shell structure, a rotating structure, and a cable structure. The rotating structure enables the stretching and retraction of the cable structure, but its relatively weak strength results in weak stability of the data cable structure. In this application's data cable device, the winding member 200 may include a first cylindrical portion 210 and a second cylindrical portion 220. The first cylindrical portion 210 is circumferentially closed, and the two cylindrical portions significantly improve the structural rigidity of the winding member 200, thereby enhancing the structural stability of the data cable device. Simultaneously, an elastic member 530 is disposed within the cavity defined by the first cylindrical portion 210, which is also circumferentially closed. The first cylindrical portion 210 completely separates at least one first cable 310 from the elastic member 530, preventing contact between the first cable 310 and the elastic member 530. This prevents the elastic member 530 from causing wear on the first cable 310, thereby improving the service life of the first cable 310.

[0197] The housing 100, winding member 200, and elastic member 530 have been described in the above embodiments and will not be repeated here. The winding member 200 in the fully retractable cable reel of the above embodiments may include a first cylindrical portion 210 and a second cylindrical portion 220. Of course, the winding member 200 in the fully retractable cable reel of the above embodiments may also include only one cylindrical portion.

[0198] In this embodiment, the number of at least one first cable 310 can be one or at least two. When the number of at least one first cable 310 is at least two, the at least two first cables 310 are wound side-by-side around the second cylindrical portion 220, and the at least two first cables 310 can be mostly housed within the housing 100. Here, the data cable device forms a fully retractable cable reel similar to the one described in the above embodiment. This embodiment is mainly described using the example of at least two first cables 310. Of course, the number of at least one first cable 310 can also be one. This application does not limit this.

[0199] In this embodiment, the elastic element 530 can be connected to the winding element 200 by means of bonding, snapping, etc.

[0201] In some optional implementations of the embodiments of this application, the number of first cables 310 can be at least two. At least two first cables 310 can be wound in parallel around the second cylindrical portion 220 so that at least two first cables 310 can be mostly stored inside the housing 100, thereby achieving full storage of at least two first cables 310. Compared with data cables with multiple sub-cables located outside the housing 100, the space occupied by the data cable device in the stored state can be greatly reduced.

[0202] In this implementation, the number of first through slots 221 is not limited. For example, the number of first through slots 221 can be one, and the second ends 311 of at least two first cables 310 can be located within the mounting space 202 through the same first through slot, such as... Figure 3As shown, the structure of the data cable device is simplified. Of course, the number of first through slots 221 can also be at least two, and the second ends 311 of at least two first cables 310 can be located in the mounting space 202 through different first through slots 221; here, the number of first through slots 221 can be the same as the number of first cables 310, so that the second end 311 of each first cable 310 can be located in the mounting space 202 through one first through slot 221.

[0203] In this implementation, the number of first openings 101 is not limited. For example, the number of first openings 101 can be one, and the first ends of at least two first cables 310 can be located outside the housing 100 through the same first opening 101, thereby simplifying the structure of the data cable device. Of course, the number of first openings 101 can also be at least two, and the first ends of at least two first cables 310 can be located outside the housing 100 through different first openings 101. Here, the number of first openings 101 and the number of first cables 310 can be the same.

[0205] In this implementation, the housing 100 may also have a second opening 102 communicating with the receiving cavity 103; the second cylindrical portion 220 may also have a second through groove 222 communicating with the mounting space 202; the data cable device may also include: a second cable 320, which is used to be wound together with at least two first cables 310 on the winding member 200 and electrically connected to the first cables 310; the first end of the second cable 320 passes through the second opening 102 and is located outside the housing 100; the second end 321 of the second cable 320 passes through the second through groove 222 and is located in the mounting space 202; thereby enabling the data cable device to quickly adjust the length of the cable by stretching both ends.

[0206] Here, the second end 321 of the second cable 320 can be directly connected to the second ends 311 of at least two first cables 310, so that one of the first cables 310 can be electrically connected to the second cable 320.

[0207] Of course, the data cable device may also include: a circuit board 520 and a functional component 730. The circuit board 520 may be disposed on the winding member 200 by means of adhesive bonding, snap-fitting, etc.; the second end 321 of the second cable 320 may be connected to the second end 311 of at least two first cables 310 respectively through the circuit board 520; the functional component 730 is disposed on the circuit board, and the functional component 730 is used to enable at least two first cables 310 to be electrically connected to the second cable 320 at the same time; thereby enabling two first cables 310 to work simultaneously through the circuit board 520 and the functional component 730.

[0208] The circuit board 520 and functional component 730 have been described in the above embodiments and will not be repeated here. Of course, the data cable device may also include only the circuit board 520, where at least one of the two first cables 310 is electrically connected to the second cable 320.

[0209] In this implementation, the data cable device may further include a circuit board 520, an interface component, and a functional component 730. The circuit board 520 is disposed on the winding member 200; the circuit board 520 is electrically connected to the second ends 311 of at least two first cables 310 respectively; the interface component may be disposed on the housing 100 and electrically connected to the circuit board 520; the interface portion of the interface component is exposed through a third opening in the housing 100; the functional component 730 is disposed on the circuit board, and the functional component 730 is used to enable at least two first cables 310 to be electrically connected to the interface component simultaneously. The circuit board 520 and the functional component 730 enable at least two first cables 310 to be electrically connected to the interface component simultaneously, and the interface component and at least two first cables 310 enable the data cable device to be stretched at one end to adjust the cable length.

[0210] The circuit board 520, interface components, and functional components 730 have been described in the above embodiments, and will not be repeated here.

[0212] In this implementation, the shape of the first plate portion 230 is limited. For example, the first plate portion 230 can be a circular plate structure to reduce the installation space of the winding member 200. Of course, the first plate portion 230 can also be a square plate structure.

[0213] The first plate portion 230 may have at least one third through slot; the data cable device may further include: a circuit board 520, which may be disposed on the side of the first plate portion 230 away from the first cylindrical portion 210 by means of adhesive bonding, snap-fitting, etc., and electrically connected to the second ends 311 of at least two first cables 310 and the second ends 321 of the second cable 320 respectively through at least one third through slot; the first plate portion 230 can separate the circuit board 520 and the elastic member 530, thereby preventing the circuit board 520 and the elastic member 530 from affecting each other.

[0214] Here, as Figure 4 As shown, at least one third through slot may include: a first sub-third through slot 231 and a second sub-third through slot 232 spaced apart; the second ends 311 of at least two first cables 310 can be connected to different areas of the circuit board 520 through the first sub-third through slot 231; the second ends 321 of the second cables 320 can be connected to the circuit board 520 through the second sub-third through slot 232; wherein, the cross-sectional area of ​​the first sub-third through slot 231 is larger than that of the first sub-third through slot 232. By providing multiple third through slots, it is possible to ensure that the second ends 321 of the second cables 320 and the second ends 311 of at least two first cables 310 do not interfere with each other, and to prevent a single large-sized third through slot from affecting the strength of the first board portion 230. Of course, in other examples, the number of at least one third through slot may also be one.

[0217] The shape of the second plate portion 240 is defined. For example, the second plate portion 240 can be a circular plate structure to reduce the installation space of the winding member 200. Of course, the second plate portion 240 can also be a square plate structure.

[0218] Here, as Figure 5 As shown, the second plate portion 240 may have a fourth through slot 241 and a fifth through slot 242; the fourth through slot 241 may communicate with the first through slot 221; the fifth through slot 242 may communicate with the second through slot 222, so that the second end 311 of the first cable 310 and the second end 321 of the second cable 320 can be installed. Of course, in other examples, the second plate portion 240 may not have the fourth through slot 241 and the fifth through slot 242.

[0219] Of course, in other examples, the positioning element 510 can also be set at other positions of the winding element 200. The positioning element 510 has been described in the above embodiments and will not be repeated here.

When the number of at least one first cable 310 is one, the first cable 310 and the second cable 320 can be directly connected by means of adhesive bonding, snap-fitting, or other methods. Of course, the first cable 310 and the second cable 320 can also be different parts of a single cable.

[0223] In some optional implementations of the embodiments of this application, such as Figure 2 and Figure 8 As shown, the fully retractable cable winder and data cable device may also include a first decorative element 610 and a second decorative element 620.
