Description

Technical Field

[0001] This utility model relates to the field of electronic device accessories technology, specifically to a retractable data cable. Background Technology

[0002] Retractable data cables are data cable products that are easy to store and carry. The retractable cable can be pulled out for use and automatically retracts into a cable winder when needed, achieving the purpose of storage. However, in related technologies, retractable data cables typically only allow the cable to be fixed at a limited number of lengths during use, and cannot be adjusted to meet the user's needs, thus affecting the user experience. Utility Model Content

[0003] In view of this, the present invention provides a retractable data cable to solve the problem that the extension length of existing retractable data cables cannot be arbitrarily adjusted.

[0004] To solve the above problems, the technical solution of this utility model is implemented as follows:

[0005] A retractable data cable includes: a housing having an internal mounting cavity; a winding assembly disposed within the mounting cavity and connected to the housing; a cable wound around the winding assembly and capable of extending out of the mounting cavity, the winding assembly being at least used to drive the cable to wind up into the mounting cavity; a damping member movably disposed between the housing and the winding assembly and abutting against the winding assembly to apply resistance to prevent movement of the cable; and an unlocking assembly at least connected to the housing, the unlocking assembly being used to drive the damping member to move away from the winding assembly.

[0006] In some embodiments, the winding assembly includes: a winding spool rotatably connected to the housing, the wire wound on the winding spool; a winding drive for driving the wire to wind into the mounting cavity, the winding drive being at least connected to the housing; wherein the damping member abuts against the winding spool.

[0007] In some embodiments, the housing is provided with a rotating shaft, the damping element is provided with a connecting hole, and the rotating shaft passes through the connecting hole.

[0008] In some embodiments, the housing is provided with a limiting member, and the damping member is provided with a limiting groove, with the limiting member located within the limiting groove to limit the rotation range of the damping member.

[0009] In some embodiments, the retractable data cable further includes a locking member, at least connected to the damping member, the locking member being used to drive the damping member to press against the reel to lock the reel.

[0010] In some embodiments, the damping element has an abutment surface for abutting against the reel; wherein, along the rotational direction in which the damping element presses against the reel, the distance from the abutment surface to the shaft decreases.

[0011] In some embodiments, the contact surface is an arcuate surface, and the center of the arcuate surface is offset from the axis of the rotating shaft.

[0012] In some embodiments, the unlocking component includes: an unlocking button for driving the damping element to move away from the reel; and a reset element for driving the unlocking button to reset, the reset element being disposed between the housing and the unlocking button.

[0013] In some embodiments, the unlock button is provided with an abutment portion for abutting against the damping member; wherein, the housing is provided with a first guide structure, and the abutment portion is provided with a second guide structure movably connected to the first guide structure to guide the movement of the abutment portion.

[0014] In some embodiments, the first guide structure is a guide groove formed on the housing, and the second guide structure is an inclined surface tilted away from the damping member; wherein, the abutment portion is movably inserted into the guide groove, and the inclined surface slides along the inner wall of the guide groove to drive the abutment portion to abut against the damping member.

[0015] The retractable data cable provided in this embodiment includes a housing, a winding assembly, a cable body, a damping element, and an unlocking component. The winding assembly drives the cable body to wind up. The damping element is movably disposed between the housing and the winding assembly and abuts against the winding assembly. The unlocking component is at least connected to the housing and can drive the damping element to move away from the winding assembly. With this design, when the cable body is extended for use, the damping element applies resistance to the winding assembly, preventing the winding assembly from driving the cable body to wind up, thus maintaining the current extended length of the cable. Furthermore, by maintaining stable contact between the damping element and the winding assembly, the extended length of the cable body can be adjusted arbitrarily. When it is necessary to wind up the cable body, simply operate the unlocking component to drive the damping element away from the winding assembly, thereby reducing or eliminating the resistance applied by the damping element to the winding assembly, allowing the cable body to wind up under the drive of the winding assembly. This is convenient to operate. A portion of the resistance can also be retained to slow down the winding speed, effectively preventing collisions or scratches between the cable body and the user or other objects, resulting in high safety and a good user experience.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] The specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction. For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this utility model will not be described separately.

[0024] In the following description, the terms "first," "second," etc., are used merely to distinguish different objects and do not indicate that the objects have the sameness or relationship. It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the orientation under normal use conditions, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions under normal use conditions.

[0025] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more.

[0026] like Figure 1 and Figure 2 As shown, this embodiment of the utility model provides a retractable data cable 1, including a housing 11, a winding assembly 12, a cable 13, a damping element 14, and an unlocking assembly 15. The housing 11 has an internal mounting cavity 111, and the winding assembly 12 is disposed within the mounting cavity 111 and connected to the housing 11. The cable 13 is wound around the winding assembly 12 and can be extended out of the mounting cavity 111 under external force for use, i.e., to connect to electronic devices such as computers and mobile phones to charge the devices or to transmit data between the two devices. When the cable 13 is pulled out, the applied force also acts on the winding assembly 12, causing the winding assembly 12 to deform, thereby applying a driving force to the cable 13, causing the cable 13 to tend to retract onto the winding assembly 12. Therefore, after the external force is removed, the winding assembly 12 can retract the pulled-out cable 13, allowing the cable 13 to be wound back onto the winding assembly 12, facilitating the carrying or storage of the retractable data cable 1. The damping element 14 is movably disposed between the housing 11 and the winding assembly 12, and abuts against the winding assembly 12, thereby applying resistance to the winding assembly 12 to prevent movement of the cable 13. The unlocking element 15 is connected at least to the housing 11, and the unlocking element 15 can drive the damping element 14 to move away from the winding assembly 12, thereby reducing or eliminating the resistance applied by the damping element 14 to the winding assembly 12.

[0027] Specifically, the damping element 14 abuts against the winding assembly 12 and applies resistance to the winding assembly 12 at the abutment position. This resistance overcomes the driving force of the winding assembly 12 in driving the cable 13 to wind up, thus preventing the cable 13 from winding up. Therefore, when the cable 13 is extended for use, it can maintain its current extended state without retracting, meeting the usage requirements of the cable 13. Furthermore, since the damping element 14 is in contact with the winding assembly 12 but not directly with the cable 13, regardless of the extension length of the cable 13, the damping element 14 maintains a stable and reliable contact with the winding assembly 12, ensuring that the resistance applied by the damping element 14 remains stable. In this way, users can stretch the cable 13 to a specified extension length according to different usage needs. When the user finishes stretching the cable 13 and removes the external force, the resistance applied to the winding assembly 12 by the damping element 14 can keep the cable 13 at that extension length, thereby enabling arbitrary adjustment of the extension length of the cable 13 with high precision, providing users with a good user experience.

[0028] Regarding the number of damping elements 14, optionally, there can be only one damping element 14 or multiple damping elements 14. When multiple damping elements 14 are provided, each damping element 14 can be evenly distributed in the space between the housing 11 and the winding assembly 12, and each damping element 14 abuts against the winding assembly 12. Of course, the damping elements 14 do not have to be evenly distributed; they only need to abut against the winding assembly 12. It is understood that the number and position of the damping elements 14 can be flexibly designed, and are usually designed according to factors such as the force balance of the winding assembly 12 and the magnitude of the applied resistance.

[0029] Specifically, the unlocking component 15 can typically be moved by the user, driving the damping element 14 to move away from the winding assembly 12. This reduces the mutual pressure between the damping element 14 and the winding assembly 12, thereby reducing the resistance applied by the damping element 14, or completely separating the damping element 14 from the winding assembly 12, thus completely releasing the resistance applied by the damping element 14. When the resistance applied by the damping element 14 is less than the driving force of the winding assembly 12 to drive the cable 13 to wind up, or when it is completely released, the winding assembly 12 can drive the cable 13 to wind up into the mounting cavity 111. In this way, the user can complete the storage of the cable 13 by operating the unlocking component 15 to drive the damping element 14, making it convenient to carry or store the retractable data cable 1, and providing easy operation.

[0030] Optionally, in some implementations, the unlocking component 15 can drive the damping component 14 to move only a small amplitude, so that the damping component 14 can still apply a certain resistance to the winding assembly 12. This resistance only needs to be slightly less than the driving force of the winding assembly 12 to drive the cable 13 to wind up. With this design, not only can the winding assembly 12 drive the cable 13 to wind up, but the winding speed of the cable 13 can also be effectively controlled, so that the cable 13 winds up more slowly and smoothly. This can better avoid the end of the cable 13 outside the housing 11 from shaking violently when the winding speed of the cable 13 is too fast, which could cause collisions or scratches to the user or other objects, thus improving the safety of the cable 13 when winding up.

[0031] It should be noted that, in order for the cable 13 to be extended and reused after winding, the unlocking component 15 typically needs to return to its initial position so that the damping element 14 can return to its abutting state with the winding assembly 12. To achieve the reset of the unlocking component 15, optionally, in some embodiments, the unlocking component 15 can be manually controlled to return to its initial position; in other embodiments, a flexible component can be used to drive the unlocking component 15 to automatically return to its initial position. Specific implementation methods are described in detail in the following embodiments.

[0032] Regarding the connection between the unlocking component 15 and the damping element 14, optionally, in some embodiments, the unlocking component 15 can always remain connected to the damping element 14, thereby achieving synchronous movement of the damping element 14 and the unlocking component 15; in other embodiments, the unlocking component 15 can only connect to the damping element 14 when it is necessary to drive the damping element 14 to move, and disengage from the damping element 14 when it is not necessary to drive the damping element 14 to move. In some embodiments, when multiple damping elements 14 are provided, the unlocking component 15 can drive each damping element 14 to move simultaneously, so that each damping element 14 moves away from the winding assembly 12 at the same time; of course, the unlocking component 15 can also drive only a portion of the damping elements 14 to move, so that a portion of the damping elements 14 moves away from the winding assembly 12. This can also achieve the effect of reducing resistance, while retaining some resistance to limit the winding speed of the yarn 13. The above solution can be flexibly selected, as long as the unlocking component 15 is at least connected to the housing 11 and can drive the damping component 14 to move away from the winding component 12 when the winding body 13 needs to be wound.

[0033] The retractable data cable 1 provided in this embodiment includes a housing 11, a winding assembly 12, a cable body 13, a damping element 14, and an unlocking assembly 15. The damping element 14 is movably disposed between the housing 11 and the winding assembly 12, and abuts against the winding assembly 12. By applying resistance to the winding assembly 12 through the damping element 14, the cable body 13 is prevented from being wound up by the winding assembly 12, thus keeping the cable body 13 in an extended state without retraction. Furthermore, regardless of the extension length of the cable body 13, the damping element 14 maintains a stable and reliable contact with the winding assembly 12. The damping element 14 can continuously apply stable resistance, fixing the cable body 13 at any extension length, thereby enabling arbitrary adjustment of the extension length of the cable body 13 with high precision. When it is necessary to rewind the cable 13, the unlocking component 15 drives the damping component 14 to move away from the winding assembly 12, thereby reducing or eliminating the resistance exerted by the damping component 14 on the winding assembly 12. This allows the winding assembly 12 to drive the cable 13 to rewind, facilitating the carrying or storage of the retractable data cable 1. When retracting the cable 13, a certain amount of resistance can be retained to slow down the rewinding speed, making the rewinding process slower and smoother. This effectively prevents the cable 13 from causing collisions or scratches to the user or other objects, improving the safety of rewinding the cable 13. Through the above design, the retractable data cable 1 provided by this embodiment can adjust the extended length of the cable 13 or retract it according to the user's needs. It is simple and convenient to use, has high safety, and provides a good user experience.

[0034] In some embodiments, such as Figure 2 As shown, the cable winding assembly 12 includes a cable reel 121 and a winding drive 122. The cable reel 121 is rotatably connected to the housing 11, the cable 13 is wound on the cable reel 121, and the damping member 14 abuts against the cable reel 121. The winding drive 122 is used to drive the cable 13 to wind into the mounting cavity 111, and the winding drive 122 is at least connected to the housing 11.

[0035] Some implementation schemes, such as Figure 2 As shown, the inner side of the housing 11 can be provided with a connecting shaft 112 for rotatably connecting the winding reel 121. The winding drive 122 can be a torsion spring, with the center of the torsion spring fixed to the connecting shaft 112. The movable end of the torsion spring is connected to the yarn body 13. When the yarn body 13 unfolds and extends, the torsion spring deforms, thereby generating an elastic force to drive the yarn body 13 to wind up automatically. In other embodiments, the winding drive 122 can also be in the form of a drive motor, etc. The user can control the motor to start as needed, thereby driving the yarn body 13 to wind up. Regarding the connection method of the winding drive 122,

[0036] Optionally, in some embodiments, the winding drive 122 can be connected to the yarn body 13, thereby directly applying a driving force to the yarn body 13 to wind it up; in some embodiments, the winding drive 122 can be connected to the winding reel 121, driving the winding reel 121 to rotate and causing the winding reel 121 to drive the yarn body 13 to wind up; in some embodiments, the winding drive 122 can also be connected to both the yarn body 13 and the winding reel 121, as long as the winding drive 122 can achieve the function of driving the yarn body 13 to wind up.

[0037] In the above embodiments, since the rotation of the reel 121 relative to the housing 11 is relatively stable and the reel 121 is not easily deformed, the damping element 14 is used to abut against the reel 121, so that the reel 121 can maintain full contact with the damping element 14 at any position, and the contact stability is good, thereby better realizing the arbitrary adjustment of the extension length of the line 13.

[0038] In some embodiments, such as Figure 2 and Figure 3 As shown, a rotating shaft 113 is provided on the housing 11, and a connecting hole 141 is provided on the damping member 14, through which the rotating shaft 113 passes. With this design, the damping member 14 can rotate around the rotating shaft 113 and move closer to or away from the winding reel 121 during rotation.

[0039] Optionally, the axis of the rotating shaft 113 and the axis of rotation of the winding reel 121 relative to the housing 11 can be parallel to each other, perpendicular to each other, or arranged at a certain angle, as long as the damping element 14 can move closer to or away from the winding reel 121 when rotating around the rotating shaft 113. For example, in some embodiments, such as Figure 2 and Figure 3As shown, the axis of the rotating shaft 113 and the axis of rotation of the reel 121 relative to the housing 11 are parallel to each other, and both axes are parallel to direction A in the figure. Assuming that the reel 121 rotates around direction B in the figure when winding the cable 13, then when the damping member 14 approaches the reel 121, it can rotate around the opposite direction to direction B. In this way, when the cable 13 is extended for use, the reel 121 has a tendency to rotate around direction B under the action of the winding drive member 122, which can drive the damping member 14 to rotate around the opposite direction to direction B, causing the damping member 14 to further press the reel 121, increasing the resistance applied by the damping member 14 to the reel 121, thereby preventing the rotation of the reel 121 and keeping the cable 13 at its current extended length. When it is necessary to rewind the cable 13, the user can operate the unlocking component 15 to drive the damping component 14 to rotate around direction B and move away from the reel 121. Then, the reel 121 can rotate around direction B under the driving action of the winding drive component 122 to rewind the cable 13 into the mounting cavity 111. The above solution has an ingenious structural design and high reliability, which can effectively keep the cable 13 at any extended length and also achieve convenient recycling of the cable 13.

[0040] In some embodiments, such as Figure 3 As shown, a limiting member 114 is provided on the housing 11, and a limiting groove 142 is formed on the damping member 14. The limiting member 114 is located within the limiting groove 142 to limit the rotation range of the damping member 14. Specifically, the shape and size of the limiting groove 142 can be designed according to the required rotation range of the damping member 14, so that when the damping member 14 rotates around the axis 113 to the limit position, the inner wall of the limiting groove 142 abuts against the limiting member 114, thereby preventing further rotation of the damping member 14. With this design, the movement of the damping member 14 can be better controlled, preventing problems such as damage to the component or difficulty in resetting due to excessive rotation of the damping member 14. Especially when the user operates the unlocking component 15 to drive the damping member 14 to rotate to the limit position, the abutment between the inner wall of the limiting groove 142 and the limiting member 114 serves as a prompt to the user, effectively avoiding damage to the component due to careless operation.

[0041] In some embodiments, such as Figure 2 and Figure 3As shown, the retractable data cable 1 also includes at least a locking member 16 connected to the damping member 14. The locking member 16 drives the damping member 14 to press against the reel 121, thereby locking the reel 121. It is understood that the direction in which the locking member 16 drives the damping member 14 is opposite to the direction in which the unlocking component 15 drives the damping member 14, and the function of the locking member 16 is also opposite to that of the unlocking component 15. The number and position of the locking members 16 can be designed according to the number and position of the damping members 14. For example, when there are multiple damping members 14, there can also be multiple locking members 16, so that each locking member 16 corresponds one-to-one with a damping member 14 and drives the corresponding damping member 14 to move. Of course, the number of locking members 16 can be less than the number of damping members 14, that is, the locking member 16 can only drive a portion of the damping members 14 to press against the reel 121. This design can also increase the resistance applied by the damping members 14, achieving the effect of locking the reel 121.

[0042] Optionally, in some embodiments, the locking member 16 can adopt a design similar to the unlocking component 15, that is, the movement of the locking member 16 is controlled by manual operation, which drives the damping member 14 to press the reel 121; in other embodiments, the locking member 16 can be a resilient component, which automatically presses the reel 121 by applying an elastic force to the damping member 14. When the locking member 16 adopts a resilient component, optionally, in some embodiments, such as Figure 3 As shown, the locking element 16 can be a spring, with one end connected to the housing 11 and the other end abutting against the damping element 14, thereby pushing the damping element 14 to press the reel 121. In other embodiments, the locking element 16 can also be a torsion spring sleeved on the rotating shaft 113, which drives the damping element 14 to rotate around the rotating shaft 113 to press the reel 121. It is understood that the design of the locking element 16 is relatively flexible, as long as it can drive the damping element 14 to press the reel 121.

[0043] In some embodiments, the damping member 14 has an abutment surface 143 for abutting against the reel 121, and the distance from the abutment surface 143 to the shaft 113 decreases along the rotational direction in which the damping member 14 presses against the reel 121. For example, as Figure 4 As shown, assuming that direction C in the figure is the direction of rotation when the damping element 14 presses against the winding reel 121, and the opposite direction to direction C is the direction of the winding body 13 of the winding reel 121 (refer to...) Figure 2As shown in the diagram, when the rotation direction is changed, the distance from the contact surface 143 to the rotating shaft 113 decreases along direction C. In other words, the distances from the two opposite ends of the contact surface 143 along direction C to the rotating shaft 113 satisfy d1 < d2. With this design, when the damping element 14 rotates in the direction of pressing the winding reel 121, the compressive force between the contact surface 143 and the winding reel 121 gradually increases with the rotation of the damping element 14, thereby better pressing and locking the winding reel 121. The structural design is ingenious.

[0044] Optionally, the shape of the contact surface 143 can be a plane, a curved surface, a combination of a plane and a curved surface, or a prism formed by combining multiple planes, as long as the distance relationship between the contact surface 143 and the rotation axis 113 is satisfied. For example, in some embodiments, such as Figure 4 As shown, the contact surface 143 can be configured as an arc-shaped surface, with the center of the arc-shaped surface offset from the axis of the rotating shaft 113. This reduces the distance between the arc-shaped surface and the rotating shaft 113 along the rotation direction in which the damper 14 presses against the winding reel 121. Specifically, the arc-shaped surface can be a circular surface, an elliptical surface, or other types of surfaces, or it can be a composite surface, such as a surface formed by combining multiple circular surfaces of different radii. When the contact surface 143 is configured as an arc-shaped surface, the smooth transitions at various points on the contact surface 143 reduce collisions and wear between the contact surface 143 and the winding reel 121, thus improving the smoothness of the movement of the damper 14 and the winding reel 121.

[0045] In some embodiments, such as Figure 2 and Figure 3 As shown, the unlocking assembly 15 includes an unlocking button 151 and a reset member 152. The unlocking button 151 drives the damping member 14 to move away from the winding reel 121, and the reset member 152 drives the unlocking button 151 to reset. The reset member 152 is disposed between the housing 11 and the unlocking button 151. Optionally, the reset member 152 can be a spring, a sheet, or other elastic component, which drives the unlocking button 151 to automatically reset by applying an elastic force to the unlocking button 151. In the above embodiment, the user can press the unlock button 151 to move the damping member 14 away from the reel 121, thereby reducing or eliminating the resistance of the damping member 14 to the reel 121, thus achieving the winding of the cable 13. After the cable 13 is wound up, the user can release the unlock button 151, causing the reset member 152 to drive the unlock button 151 back to its initial position. At the same time, the damping member 14 can re-engage with the reel 121 under the action of the locking member 16, so as to prevent the cable 13 from being wound up when it is extended for use in the future, and maintain the extended length of the cable 13. The design structure of the above embodiment is simple, and the user only needs to press the unlock button 151 to complete the winding of the cable 13, which is convenient and quick to operate.

[0046] In some embodiments, such as Figure 2 and Figure 3 As shown, the unlock button 151 is provided with an abutment portion 1511 for abutting against the damping member 14. The housing 11 is provided with a first guide structure 115, and the abutment portion 1511 is provided with a second guide structure 1512 that is movably connected to the first guide structure 115 to guide the movement of the abutment portion 1511. Specifically, the first guide structure 115 and the second guide structure 1512 have mutually adapted shapes, so that when the second guide structure 1512 moves relative to the first guide structure 115, it can move along a specific trajectory, thereby guiding the movement of the abutment portion 1511. Thus, when the unlock button 151 is pressed, the abutment portion 1511 on the unlock button 151 moves synchronously, causing the second guide structure 1512 on the abutment portion 1511 to move relative to the first guide structure 115, thereby guiding the abutment portion 1511 to move to abut against the damping member 14, and then driving the damping member 14 to move away from the winding reel 121, reducing the resistance on the winding reel 121, and causing the winding reel 121 to drive the cable 13 to wind up.

[0047] Regarding the specific form of the first guide structure 115 and the second guide structure 1512, optionally, in some embodiments, such as Figure 2 As shown, the first guide structure 115 is a guide groove formed on the housing 11, and the second guide structure 1512 is an inclined surface oriented away from the damping member 14. The abutment portion 1511 is movably inserted into the guide groove. Optionally, the inner wall of the guide groove can be inclined to correspond to the inclined surface on the abutment portion 1511, which increases the contact area between the abutment portion 1511 and the inner wall of the guide groove, improving the stability of the guide. Of course, the inner wall of the guide groove may not be inclined; only an inclined surface needs to be provided on the abutment portion 1511. With the above design, when the unlock button 151 is pressed, as... Figure 2 As shown, the inclined surface on the abutment portion 1511 slides along the inner wall of the guide groove, causing the abutment portion 1511 to press down in the direction opposite to direction A while rotating in the direction opposite to direction B towards the damping member 14. This, in turn, drives the damping member 14 to rotate in the direction opposite to direction B away from the winding reel 121. The above solution has a simple structure, achieving the guiding effect through the cooperation of the inclined surface and the guide groove. It is ingeniously designed and easy to operate. In other embodiments, the first guide structure 115 can be a guide rail disposed inside the housing 11, and the second guide structure 1512 can be a roller rotatably connected to the abutment portion 1511. In this way, the roller can also guide the abutment portion 1511 by rolling along the guide rail.

[0048] In addition to the above scheme, the first guide structure 115 and the second guide structure 1512 can also adopt other forms. Specifically, they can be designed according to the required motion relationship, motion path, etc., as long as the required guiding function can be achieved. In other words, it is only necessary to drive the damping element 14 to move away from the winding reel 121 when pressing to unlock. The design is more flexible.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
