[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] The various specific technical features described in the specific embodiments may be combined in any suitable manner, unless they are inconsistent. For example, different embodiments and technical solutions may be formed by combining different specific technical features. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this utility model will not be described separately.

[0030] In the following description, the terms "first, second, ..." are used solely to distinguish different objects and do not imply any similarities or connections between the objects. It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to directions during normal use. The directions "left" and "right" refer to the left-right directions shown in the corresponding schematic diagrams, which may or may not be the left-right directions during normal use.

[0031] It should be noted that the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus comprising that element. "A plurality" means greater than or equal to two.

[0032] like Figures 1 to 3 As shown, an embodiment of the present invention provides a retractable data cable, comprising a housing 1, a cable reel assembly 2, a cable body 3, and a friction member 4. The housing 1 has a housing 11 formed therein. The cable reel assembly 2 is disposed within the housing 1 and is connected to the housing 1. The cable body 3 is wound around the cable reel assembly 2, which can be driven by a drive component to retract the cable body 3 into the housing 11. When the cable body 3 is needed, the cable body 3 can be unwound by an external force, overcoming the driving force of the cable reel assembly 2, and extended out of the housing 1 for use, such as connecting to an electronic device such as a computer or mobile phone to charge the device or transfer data between two devices. The cable reel assembly 2 and the housing 1 are typically also provided with a locking structure for locking the extension length of the cable body 3. This ensures that the cable body 3 maintains its current extension length when extended for use and does not retract. When the cable body 3 needs to be stored, the user can unlock the locking structure through a specific operation, allowing the cable body 3 to be retracted into the housing 11 under the drive of the cable reel assembly 2. The implementation of the above-mentioned locking structure will be described in detail in the following embodiments, or it can also be designed with reference to related technologies. In order to control the movement speed of the wire body 3 during the winding or extension process, especially the speed during winding, the embodiment of the utility model adopts a friction member 4 that is at least partially disposed in the accommodating chamber 11 and abuts against the winding assembly 2 and / or the wire body 3 to apply a friction force to slow down the movement speed of the wire body 3.

[0033] Optionally, the friction member 4 can directly abut against the wire body 3, thereby directly applying friction to the wire body 3. In addition, in some embodiments, part of the structure of the winding assembly 2 can move synchronously with the wire body 3, for example, when the wire body 3 is wound or unwound, it rotates relative to the housing 1. At this time, the friction member 4 can also abut against the winding assembly 2, and by applying friction to the winding assembly 2, the rotation speed of the winding assembly 2 is controlled, thereby indirectly controlling the movement speed of the wire body 3. In some embodiments, the friction member 4 can also abut against the winding assembly 2 and the wire body 3 at the same time. Therefore, the positional relationship between the friction member 4 and the winding assembly 2 and the wire body 3 can be flexibly designed, as long as the movement speed of the wire body 3 can be controlled by applying friction.

[0034] Specifically, the friction member 4 can be designed according to the expected speed of the wire body 3 when it is wound. During the design, the driving force of the winding assembly 2 to drive the wire body 3 to wind, the roughness of the material of the wire body 3, etc. can be considered to determine the material of the friction member 4, the roughness of the surface of the friction member 4, the pressure of the friction member 4 against the friction member 4 and other parameters related to the friction force. In some embodiments, the maximum friction force (maximum static friction force) that the friction member 4 can apply when the wire body 3 is stationary is greater than the driving force of the winding assembly 2 to drive the wire body 3 to wind, and the friction force (sliding friction force) applied when the wire body 3 is moving is equal to or slightly less than the driving force of the winding assembly 2 to drive the wire body 3 to wind. It should be noted that the friction force applied by the friction member 4 should not be too small or too large. Too little friction will result in a poor effect of slowing down the speed, while too much friction will cause the wire body 3 to move poorly and cause jamming.

[0035] It is understandable that in the embodiment of the present invention, the friction force applied by the friction member 4 is mainly used to slow down the speed of the wire body 3 when it is wound, and the speed of the wire body 3 being unfolded under the action of an external force has different effects according to different design schemes. For example, in some embodiments, the friction member 4 is always in contact with the winding assembly 2 and / or the wire body 3, and the wire body 3 will also be subject to resistance from the friction member 4 when it is unfolded. Of course, it is understandable that even if the friction member 4 is always in contact with the winding assembly 2 and / or the wire body 3, the wire body 3 can still be unfolded and used normally. In some usage scenarios, the friction force applied by the friction member 4 can also, to a certain extent, prevent the wire body 3 from being damaged due to excessive stretching when it is subjected to a large pulling force.

[0036] The embodiment of the present invention provides a retractable data cable, comprising a housing 1, a winding assembly 2, a cable body 3, and a friction member 4. The winding assembly 2 is disposed within a housing 11 formed by the housing 1, and the cable body 3 is wound around the winding assembly 2. The winding assembly 2 can drive the cable body 3 to reel within the housing 11. The friction member 4 abuts against the winding assembly 2 and / or the cable body 3 to apply a friction force for slowing down the movement of the cable body 3. By applying friction using the friction member 4, the movement speed of the cable body 3 can be effectively controlled, especially the reeling speed driven by the winding assembly 2, thereby effectively preventing the cable body 3 from being reeled in too quickly and causing damage to the user or the housing 1, thereby improving safety during reeling and providing a better user experience.

[0037] In some embodiments, such as Figure 2 and Figure 3As shown, the retractable data cable also includes a control component 5 connected to the friction member 4, and the control component 5 is at least used to control the friction member 4 to abut or separate from the winding assembly 2 and / or the wire body 3. Optionally, the control component 5 can be in the form of a button, a knob, a toggle switch, etc., as long as it can drive the friction member 4 to move by being connected to the friction member 4, thereby achieving control over the contact or separation of the friction member 4 and the winding assembly 2 and / or the wire body 3. In some embodiments, the control component 5 always controls the friction member 4 to be in a separated state when no external force is applied, and controls the friction member 4 to abut against the winding assembly 2 and / or the wire body 3 when the user operates it; other embodiments are the opposite of the above embodiments, that is, the control component 5 always controls the friction member 4 to abut against the winding assembly 2 and / or the wire body 3 when no external force is applied, and controls the friction member 4 to separate when the user operates it. The above two implementation schemes can be flexibly selected according to needs. It is understandable that by setting the control component 5 to be connected to the friction member 4, the user can choose to operate or not operate the control component 5 according to different needs, so that the friction member 4 is separated from the winding component 2 and / or the wire body 3 when the wire body 3 is unfolded, and is in contact with the winding component 2 and / or the wire body 3 when the wire body 3 is reeled. Through such a setting, the friction force applied by the friction member 4 will not affect the normal unfolding and use of the wire body 3, and the unfolding of the wire body 3 will be smoother. When the wire body 3 is reeled, the friction force applied by the friction member 4 can slow down the reeling speed of the wire body 3 and improve safety, thereby better meeting the needs of users in different situations. It should be noted that in addition to controlling the contact and separation of the friction member 4, the control component 5 can also be used to control other components in some designs to achieve more functions, which will be explained in detail in the following embodiments.

[0038] In some embodiments, such as Figures 2 to 4 As shown, the wire winding assembly 2 includes a wire winding seat 21 and a winding drive 22. The wire winding seat 21 is rotatably connected to the housing 1, and the wire body 3 is wound on the wire winding seat 21. The winding drive 22 is used to drive the wire winding seat 21 to rotate to wind up the wire body 3, and the winding drive 22 is at least connected to the wire body 3 and the housing 1. Among them, the friction member 4 abuts against the wire winding seat 21 and / or the wire body 3. For example, in some embodiments, a connecting shaft 12 for rotatably connecting the wire winding seat 21 is provided on the inner side of the housing 1, and the winding drive 22 adopts a torsion spring, the center of the torsion spring is fixed on the connecting shaft 12, and the movable end of the torsion spring is connected to the wire body 3 and the wire winding seat 21. When the wire body 3 is unfolded, the wire winding seat 21 rotates relative to the housing 1, and the torsion spring is deformed, thereby generating an elastic force to drive the wire body 3 to reel, and can drive the wire body 3 to reel automatically. In other embodiments, the winding drive 22 can also be in the form of a drive motor, etc., and the motor can be controlled to start or shut down by electronic control. At this time, the winding drive 22 can only connect the wire body 3 and the shell 1, as long as the winding drive 22 drives the wire body 3 to be wound in the accommodating cavity 11.

[0039] In some embodiments, such as Figure 2 and Figure 3 As shown, the retractable data cable also includes a stopper 6, and a plurality of stop positions 211 are provided on the winding seat 21. The stopper 6 is used to abut against any one of the stop positions 211 to lock the winding seat 21. The control component 5 is connected to the stopper 6 to control the abutment or separation of the stopper 6 and the stop position 211. In the above embodiment, when the stopper 6 abuts against the stop position 211, the rotation of the winding seat 21 can be prevented to achieve locking. In this way, when the line body 3 is extended out of the housing 1 for use, when the stopper 6 abuts against different stop positions 211, the line body 3 can be maintained at different extended lengths. The more stop positions 211 are set, the more selectable gears are for maintaining the extended length of the line body 3. At the same time, by adopting the control component 5 to connect with the stopper 6, the user can control the stopper 6 to abut against the stopper 211 when the wire body 3 needs to be used, thereby preventing the wire body 3 from being wound, and control the stopper 6 to separate from the stopper 211 when the wire body 3 needs to be stored, so that the wire body 3 can be wound normally. The configuration is more flexible and can better meet the use requirements. In addition, the above embodiment can also realize the simultaneous control of the friction member 4 and the stopper 6 by the same control component 5. For example, the control component 5 can control the friction member 4 to abut against the winding seat 21 and / or the wire body 3 while controlling the stopper 6 to separate from the stopper 211. In this way, the winding speed can be controlled when the wire body 3 is wound, and the wire body 3 can be smoothly unfolded when it is unfolded, and the extended length of the wire body 3 can be maintained during use, thereby better meeting the use requirements and improving the user experience.

[0040] In some embodiments, such as Figure 2 and Figure 3As shown, the control assembly 5 includes a control button 51 and an elastic member 52. The stopper 6 and the friction member 4 are both connected to the control button 51. The elastic member 52 is used to drive the control button 51 to reset. The elastic member 52 is connected to the housing 1 and the control button 51. In the above embodiment, the user can press the control button 51 to move the stopper 6 and the friction member 4, switching the connection state of the stopper 6 and the friction member 4 with the relevant components between abutment and separation, and compressing the elastic member 52. When the control button 51 is released, the elastic member 52 rebounds to reset the control button 51, and at the same time, drives the stopper 6 and the friction member 4 back to the connection state before the control button 51 was pressed. For example, in some embodiments, when the control assembly 5 is not pressed, the stopper 6 abuts against the stopper 211, and the friction member 4 is in a separated state. At this time, the cable reel 21 cannot rotate, and the extended length of the cable body 3 can be maintained for use. When the control assembly 5 is pressed, the stopper 6 separates from the stopper 211, allowing the cable reel 21 to rotate normally. At the same time, the friction member 4 abuts against the cable reel 21 and / or the cable body 3 to apply friction, which can slowly reel the cable body 3. With this design, the user only needs to press the control button 51 to reel the cable body 3, achieving one-touch reeling and more convenient operation.

[0041] In some embodiments, such as Figure 2 and Figure 3 As shown, the stop member 6 includes a stop rod 61 and a rotating shaft 62. One end of the stop rod 61 is connected to the control assembly 5. For example, if the control assembly 5 includes a control button 51 and an elastic member 52, one end of the stop rod 61 is connected to the control button 51. The other end of the stop rod 61 is movably connected to any one of the stop positions 211. The rotating shaft 62 is movably connected to the stop rod 61 and connected to the housing 1, allowing the ends of the stop rod 61 to swing about the rotating shaft 62. This arrangement forms a lever structure for the stop member 6. When one end of the stop rod 61 connected to the control assembly 5 moves, the other end of the stop rod 61 synchronously swings about the rotating shaft 62, thereby causing the stop rod 61 to engage or disengage with the stop position 211. In some embodiments, the rotating shaft 62 can also be fixedly connected to the stop rod 61, and a connecting sleeve adapted to the rotating shaft 62 can be provided on the housing 1. The rotating shaft 62 and the connecting sleeve are rotatably connected, which can also enable the ends of the stop rod 61 to swing about the axis of the rotating shaft 62. In some embodiments, the positional relationship between the stop rod 61 and the rotating shaft 62 can be designed so that the distance from one end of the stop rod 61 connected to the control component 5 to the rotating shaft 62 is smaller than the distance from the other end to the rotating shaft 62. In this way, only a small movement of one end of the stop rod 61 connected to the control component 5 can drive the other end to swing more widely, enabling the stop rod 61 to fully contact or completely separate from the stop position 211, thereby achieving better control over the stop rod 61.

[0042] In some embodiments, such as Figure 2 and Figure 3 As shown, the axis of the rotating shaft 62 is parallel to the axis of rotation of the winding seat 21 relative to the housing 1. In this design, when the stop rod 61 abuts the stop position 211, the direction of rotation of the winding seat 21 relative to the housing 1 is opposite to the direction of swinging of the stop rod 61 around the rotating shaft 62. In some embodiments, such as Figure 3 As shown, it is assumed that when the wire body 3 is wound, the winding seat 21 needs to be Figure 3 When the cable reel 21 is rotated clockwise from the perspective shown, and the stop lever 61 abuts the stop position 211, the stop lever 61 will tend to swing counterclockwise under the influence of the cable reel 21. However, the stop lever 61 is affected by the control assembly 5, for example, the stop lever 61 is connected to the control button 51, and the control button 51 is pulled by the elastic member 52 to prevent the stop lever 61 from swinging further. In this way, the contact between the stop lever 61 and the stop position 211 can be maintained stable, thereby effectively preventing the cable reel 21 from rotating and keeping the cable 3 in the extended state. Conversely, when the cable 3 is extended outward, the cable reel 21 is driven by the cable 3 to rotate counterclockwise. The part of the cable reel 21 that forms the stop position 211 compresses the abutting end of the stop lever 61. Due to the external force applied by a sufficient amount, the cable reel 21 can push the stop lever 61 to swing clockwise and temporarily separate from the stop position 211, so that the user can smoothly pull the cable 3 outward. With this design, when the stop rod 61 is in contact with the stop position 211, the wire 3 can be extended outward and maintained at the extended length without retracting. This achieves a one-way locking effect that only restricts the retraction of the wire 3 without restricting its extension, without operating the control assembly 5. When the wire 3 needs to be retracted, the stop rod 61 can be separated from the stop position 211 by operating the control assembly 5, for example, by pressing the control button 51, to smoothly reel the wire 3. This makes the operation flexible and convenient, and provides a better user experience.

[0043] In some embodiments, such as Figure 3As shown, at least part of the winding seat 21 is a gear, and the teeth of the gear form a stop position 211. Optionally, the winding seat 21 can directly use a standard gear, or it can be processed based on the standard gear, and non-standard gears can also be designed according to needs. The teeth of the gear can form a plurality of evenly distributed stop positions 211. It is only necessary to determine the number of teeth of the gear according to the required number of stop positions 211. In this way, the density of the teeth can be set according to the needs of the positioning length, so that the length adjustment of the wire body 3 is more precise. In order to better cooperate with the stop position 211 to achieve the locking of the winding seat 21, in some embodiments, the end of the stop member 6 that abuts the stop position 211 is provided with a tooth groove corresponding to the teeth of the gear. Through the meshing of the tooth groove and the teeth, full contact is maintained during locking, and stability is better. The above embodiment uses the teeth of the gear to form the stop position 211, and the density of the teeth can also be designed according to needs, so that the length adjustment of the wire body 3 is more precise. Furthermore, the teeth of the gears on the stopper 6 can be meshed with the teeth to enhance locking stability and achieve a better locking effect. In addition, compared to the gear structure of some existing retractable data cable products, the teeth of the gears are less likely to wear out during long-term use, and can maintain reliable locking for a long time, with better durability.

[0044] In some embodiments, such as Figure 3 As shown, the teeth of the gear are inclined toward the winding direction of the wire body 3 wound on the winding seat 21. For example, the wire body 3 is as shown in FIG. Figure 3 When winding the spool 3 clockwise around the spool seat 21 from the perspective shown, the gear teeth are tilted clockwise at a predetermined angle. This design allows the inclined teeth to form a favorable contact angle when the stopper 6 abuts the stopper 211, thereby more stably locking the spool seat 21 and preventing the spool 3 from being wound. Furthermore, as the spool 3 extends further outward, the inclined teeth and the stopper 6 are more easily separated, ensuring smooth extension of the spool 3.

[0045] In some embodiments, such as Figure 4As shown, the retractable data cable also includes a first magnetic member 7 provided on the housing 1, the wire body 3 has a connector 31, and the connector 31 is provided with a second magnetic member 32. The first magnetic member 7 is adsorbed and connected to the second magnetic member 32 to fix the storage position of the connector 31. For example, in some embodiments, the housing 1 is provided with a storage groove 13 for accommodating the connector 31, and the first magnetic member 7 is provided in the storage groove 13. When the wire body 3 is wound, the connector 31 is received in the storage groove 13, and the second magnetic member 32 provided on the connector 31 is adsorbed and connected to the first magnetic member 7, thereby fixing the connector 31 in the storage groove 13. Of course, it is understandable that the housing 1 may not be provided with a storage groove 13, as long as the position of the connector 31 can be fixed by the adsorption connection between the first magnetic member 7 and the second magnetic member 32. By adopting the above design, the connector 31 is adsorbed on the shell 1 through the magnetic part when stored, which can better prevent the connector 31 from swinging during carrying, reduce the possibility of the connector 31 colliding with other structures and being damaged, and provide a better experience when carrying.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
