Description

Technical Field

[0001] This application relates to the field of telescopic wire technology, and in particular to a damped ultrathin telescopic wire. Background Technology

[0002] In today's society, people often need to charge their mobile devices when they go out, hence the emergence of retractable charging cables.

[0003] The problem with the aforementioned retractable cable is that it is too thick, making it inconvenient to carry and unable to meet the needs of different scenarios, resulting in a poor user experience. Utility Model Content

[0004] To address the aforementioned issues, this application provides a damped ultra-thin telescopic cable that optimizes the internal components and installation structure of the damped telescopic cable, thereby reducing its thickness, making it easier to carry, meeting the needs of different scenarios, and improving the user experience.

[0005] In a first aspect, this application provides a damped ultra-thin telescopic cable, which includes a wire, a coil spring, a winding structure, and a damping structure. The winding structure includes a winding portion, a first positioning portion, a second positioning portion, and a first damping engagement portion. The wire is wound around the winding portion, the coil spring is disposed on the first positioning portion, the second positioning portion is used to position the winding structure and enable the winding structure to rotate, and the first damping engagement portion is located on one side of the winding portion. The damping structure includes a second damping engagement portion and a mounting portion. The second damping engagement portion contacts the first damping engagement portion to provide resistance to the winding structure when it rotates, and the mounting portion is used to fix the damping structure.

[0006] The damped ultra-thin retractable cable provided in this application has a winding structure comprising a winding portion, a first positioning portion, a second positioning portion, and a first damping engagement portion. The cable is wound around the winding portion, a coil spring is disposed on the first positioning portion, and the second positioning portion is used to position the winding structure and enable it to rotate. The second damping engagement portion contacts the first damping engagement portion to provide damping for the winding structure when it rotates. Here, by integrating the winding portion, the first positioning portion, the second positioning portion, and the first damping engagement portion into one unit, there is no installation structure between the various parts. Compared to related technologies where retractable cables are too thick, inconvenient to carry, and cannot meet the needs of different scenarios, resulting in a poor user experience, the damped ultra-thin retractable cable provided in this application optimizes the installation structure between the winding portion, the first positioning portion, the second positioning portion, and the first damping engagement portion, thereby reducing the damping retractable cable's thickness. The reduced thickness of the retractable cable makes it easy to carry, meeting the needs of different scenarios and improving the user experience. Furthermore, the first damping engagement part is located on one side of the winding part. This first damping engagement part can then act as a limiting stop for the wire wound on the winding part. The damped ultra-thin retractable cable does not require additional stopping components, reducing the number of parts in the cable. Compared to related technologies where retractable cables are too thick, inconvenient to carry, and unable to meet the needs of different scenarios, resulting in a poor user experience, the damped ultra-thin retractable cable provided in this application has a first damping engagement part that, in addition to its function of cooperating with the second damping engagement part, also acts as a limiting stop for the wire wound on the winding part. This reduces the number of parts in the damped retractable cable, thereby reducing its thickness, making it easier to carry, meeting the needs of different scenarios, and improving the user experience. In summary, compared to damped retractable cables in related technologies, the damped ultra-thin retractable cable provided in this application has the beneficial effect of optimizing the internal parts and installation structure of the damped retractable cable, thereby reducing its thickness, making it easier to carry, meeting the needs of different scenarios, and improving the user experience.

[0042] Reference Figure 1 and Figure 2 This application provides a damped ultra-thin telescopic cable 1, which includes a wire 11, a coil spring 18, a winding structure 13, and a damping structure 14. The winding structure 13 includes a winding portion 132, a first positioning portion 133, a second positioning portion 134, and a first damping engagement portion 131. The wire 11 is wound around the winding portion 132. The coil spring 18 is disposed on the first positioning portion 133. The second positioning portion 134 is used to position the winding structure 13 and enable the winding structure 13 to rotate. The first damping engagement portion 131 is located on one side of the winding portion 132. The damping structure 14 includes a second damping engagement portion 142 and a mounting portion 141. The second damping engagement portion 142 and the first damping engagement portion 131 are in contact to provide resistance to the winding structure 13 when it rotates. The mounting portion 141 is used to fix the damping structure 14.

[0043] In this embodiment, the cable 11 is used to connect to the charging interface. The charging interface can be a USB Type-C interface; it can also be a Lightning interface; or it can be a MicroUSB interface. This embodiment does not limit the type of charging interface. In one possible implementation provided in this embodiment, the charging interface is a USB Type-C interface.

[0044] In this embodiment, the wire 11 is wound around the winding portion 132. Here, a portion of the wire 11 may or may not be fixed to the winding portion 132; this embodiment does not impose any limitations on this. If a portion of the wire 11 can be fixed to the winding portion 132, then that portion of the wire 11 can be non-removably fixed to the winding portion 132. For example, a portion of the wire 11 can be bonded to the winding portion 132, or, for example, a portion of the wire 11 can be soldered to the winding portion 132. Alternatively, if a portion of the wire 11 can be fixed to the winding portion 132, then that portion of the wire 11 can also be detachably fixed to the winding portion 132. For example, a portion of the wire 11 can be snapped onto the winding portion 132, or, for example, a portion of the wire 11 can be screwed onto the winding portion 132; this embodiment does not impose any limitations on this.

[0045] In this embodiment, the coil spring 18 is disposed on the first positioning part 133. Here, the coil spring 18 can be disposed on the first positioning part 133 in a non-removable manner, for example, the coil spring 18 is glued to the first positioning part 133, or the coil spring 18 is welded to the first positioning part 133. Of course, the spring can be disposed on the first positioning part 133 in a detachable manner, for example, the coil spring 18 is snapped onto the first positioning part 133, or the coil spring 18 is screwed onto the first positioning part 133. This embodiment does not limit the scope of this embodiment.

[0046] In this embodiment, the coil spring 18 is disposed on the first positioning part 133 to provide the restoring force of the wire 11 when it is elongated or shortened, thereby accelerating the restoring speed of the wire 11 when it is elongated or shortened.

[0047] In this embodiment, the second positioning part 134 is used to position the winding structure 13 and enable the winding structure 13 to rotate. The positioning of the winding structure 13 by the second positioning part 134 can be achieved by a shaft-hole fit; the positioning of the winding structure 13 by the second positioning part 134 can be achieved by a hinge connection. This embodiment does not limit the scope of this embodiment.

[0048] In this embodiment, the first damping engagement portion 131 is located on one side of the winding portion 132. Here, the first damping engagement portion 131 located on one side of the winding portion 132 can form a stop on one side of the wire 11 wound around the winding portion 132; the first damping engagement portion 131 located on one side of the winding portion 132 can also form stops on both sides of the wire 11 wound around the winding portion 132; in this respect, this embodiment does not limit the scope; in one possible implementation provided by this embodiment, the first damping engagement portion 131 located on one side of the winding portion 132 forms a stop on one side of the wire 11 wound around the winding portion 132, and the winding portion 132 forms a stop on the other side of the wire 11 wound around the winding portion 132.

[0049] In this embodiment, the second damping mating part 142 is used to contact the first damping mating part 131. Here, the second damping mating part 142 can contact the first damping mating part 131 in a way that is the meshing of gears; of course, the second damping mating part 142 can contact the first damping mating part 131 in a way that is the adaptation of concave and convex surfaces; this embodiment does not limit this; in one possible implementation provided by this embodiment, the second damping mating part 142 contacts the first damping mating part 131 in a way that is the meshing of gears.

[0050] In this embodiment, when the wire 11 is completely wound around the winding portion 132, the projection of the wire 11 on the projection plane perpendicular to the rotation axis of the winding structure 13 covers the projections of the first damping mating portion 131 and the second damping mating portion 142. When the wire 11 is completely wound around the winding portion 132, the projection of the wire 11 on the projection plane perpendicular to the rotation axis of the winding structure 13 may also partially cover the projections of the first damping mating portion 131 and the second damping mating portion 142. Of course, when the wire 11 is completely wound around the winding portion 132, the wire 11 may not completely cover the projections of the first damping mating portion 131 and the second damping mating portion 142 on the projection plane perpendicular to the rotation axis of the winding structure 13. This embodiment does not impose any limitations on this aspect.

[0051] In this embodiment, the winding structure 13 includes a first damping engagement portion 131 and a second positioning portion 134. Here, the first damping engagement portion 131 and the second positioning portion 134 can share the same pivot; of course, the first damping engagement portion 131 and the second positioning portion 134 can each have their own pivot. This embodiment does not limit this. In one possible implementation provided by this embodiment, the first damping engagement portion 131 and the second positioning portion 134 share a pivot.

[0052] In this embodiment, the damping structure 14 includes a second damping engagement portion 142 and a mounting portion 141. The second damping engagement portion 142 contacts the first damping engagement portion 131 to provide resistance to the winding structure 13 when it rotates. This resistance can prevent the wire 11 from shortening too quickly, thus reducing the risk of injury to the hand or damage to the product's appearance due to rapid shortening. Of course, this resistance can also prevent the wire 11 from elongating too quickly, thus improving the user's damping sensation when stretching the wire 11 and enhancing the user experience. Furthermore, this resistance can prevent both shortening and elongation of the wire 11; however, this embodiment does not limit this aspect. In one possible implementation provided by this embodiment, the resistance can prevent the wire 11 from shortening too quickly.

[0053] In this embodiment, the damping structure 14 includes a second damping mating part 142 and a mounting part 141. The mounting part 141 is used to fix the damping structure 14. Here, the mounting part 141 can fix the damping structure 14 in a non-removable manner, for example, by bonding the damping structure 141 together, or by welding the damping structure 14 together. Of course, the mounting part 141 can also fix the damping structure 14 in a detachable manner, for example, by snapping the damping structure 14 together, or by screwing the damping structure 14 together. This embodiment does not limit the scope of this application.

[0054] The damped ultra-thin telescopic cable 1 provided in this embodiment includes a winding structure 13 comprising a winding portion 132, a first positioning portion 133, a second positioning portion 134, and a first damping engagement portion 131. The cable 11 is wound around the winding portion 132. A coil spring 18 is disposed on the first positioning portion 133. The second positioning portion 134 positions the winding structure 13 and enables it to rotate. The first damping engagement portion 131 is located on one side of the winding portion 132, and the second damping engagement portion 142 is in contact with the first damping engagement portion 131. To provide damping for the winding structure 13 when it rotates, the winding part 132, the first positioning part 133, the second positioning part 134, and the first damping mating part 131 are integrated into one unit, with no mounting structure between the various parts. Compared to the technical problems of excessively thick telescopic cables in related technologies, which are inconvenient to carry, cannot meet the needs of different scenarios, and have a poor user experience, the damping ultra-thin telescopic cable 1 provided in this application optimizes the winding part 132, the first positioning part 133, the second positioning part 134, and the first damping mating part 131. The mounting structure between the positioning part 134 and the first damping mating part 131 reduces the thickness of the damping telescopic cable, making it easier to carry and meet the needs of different scenarios, thus improving the user experience. On the other hand, the first damping mating part 131 is located on one side of the winding part 132. At this time, the first damping mating part 131 can form a limiting stop on the wire 11 wound on the winding part 132. The damping ultra-thin telescopic cable 1 does not need to be equipped with additional stopping components, reducing the number of parts in the damping telescopic cable. Compared with the technical problems of telescopic cables being too thick, inconvenient to carry, unable to meet the needs of different scenarios, and having a poor user experience in related technologies, the damping ultra-thin telescopic cable 1 provided in this application, in addition to cooperating with the second damping mating part 142, also has the function of forming a limiting stop on the wire 11 wound on the winding part 132, reducing the number of parts in the damping telescopic cable, thereby reducing the thickness of the damping telescopic cable, making it easier to carry and meet the needs of different scenarios, thus improving the user experience. In summary, compared with telescopic cables in related technologies, the damped ultra-thin telescopic cable 1 provided in this application has the beneficial effect of optimizing the internal parts and installation structure of the damped telescopic cable, thereby reducing the thickness of the damped telescopic cable, making it easy to carry, meeting the needs of different scenarios, and improving the user experience.

When the cable 11 is completely wound around the winding part 132, on the projection plane perpendicular to the rotation axis of the winding structure 13, the projection of the cable 11 covers the projection of the first damping mating part 131 and the second damping mating part 142.

[0056] The damped ultra-thin telescopic cable 1 provided in this application embodiment, when the cable 11 is completely wound around the winding portion 132, on the projection plane perpendicular to the rotation axis of the winding structure 13, the projection of the cable 11 covers the projection of the first damping mating portion 131 and the second damping mating portion 142, thereby reducing the size of the damped ultra-thin telescopic cable 1 on the projection plane perpendicular to the rotation axis of the winding structure 13 caused by the mating of the first damping mating portion 131 and the second damping mating portion 142.

[0057] Reference Figure 4 and Figure 6 This application provides a damped ultra-thin telescopic cable 1, in which the first damping mating part 131 and the second positioning part 134 are coaxial.

[0059] Reference Figure 6 This application provides a damped ultra-thin telescopic cable 1. When the winding structure 13 rotates, the first damping engagement part 131 drives the second damping engagement part 142 to rotate. The rotation axis of the winding structure 13 is parallel to the rotation axis of the second damping engagement part 142.

[0060] The damped ultra-thin telescopic cable 1 provided in this application embodiment, when the winding structure 13 rotates, the first damping engagement part 131 drives the second damping engagement part 142 to rotate. The rotation axis of the winding structure 13 is parallel to the rotation axis of the second damping engagement part 142. In this way, the rotation efficiency of the first damping engagement part 131 driving the second damping engagement part 142 to rotate can be improved.

[0061] Reference Figure 6 This application provides a damped ultra-thin telescopic cable 1. The first damping mating part 131 includes a cable contact surface and a damping contact surface. The cable contact surface is in contact with the cable, the damping contact surface is in contact with the second damping mating part, and the cable contact surface and the damping contact surface are adjacent to each other.

[0064] The damped ultra-thin telescopic cable 1 provided in this application embodiment has a first damping mating part 131 that includes a wire contact surface and a damping contact surface, and the wire contact surface and the damping contact surface are adjacent. In this way, the distance between the wire contact surface and the damping contact surface can be shortened, thereby reducing the thickness of the damped ultra-thin telescopic cable 1.

Similarly, the outer contour of the housing 12 can be regular, for example, a cube or a cylinder; of course, the outer contour of the housing 12 can also be irregular. This embodiment also does not impose any limitations on this.

[0067] In this embodiment, a receiving cavity is formed within the housing 12. The housing 12 can be integrally formed to create the receiving cavity; alternatively, the housing 12 can be separately formed to create the receiving cavity. This embodiment does not limit the specific form of the receiving cavity. In one possible implementation provided by this embodiment, the housing 12 includes an upper cover 121 and a lower cover 122, which are fastened together to form the receiving cavity.

[0068] In this embodiment of the application, the wire 11 can extend outside the housing 12. Here, it should be explained that the wire 11 can extend outside the housing 12 through the through hole on the housing 12.

On this basis, the mounting part 141 is located outside the receiving cavity and fixed to the outer contour of the housing 12. In this way, the difficulty of arranging the components located in the receiving cavity can be reduced.

Here, the fixing structure 15 can be a snap-fit ​​type; it can also be a threaded type. This embodiment does not limit the specific type of fixing structure. In one possible implementation provided by this embodiment, the fixing structure 15 is a threaded type.

[0072] The damped ultra-thin telescopic cable 1 provided in this application embodiment has a mounting part 141 that is detachably connected to the outer contour of the housing 12 via a fixing structure 15.

[0076] Reference Figure 1 , Figure 2 , Figure 9 and Figure 10This application provides a damped ultra-thin telescopic cable 1, wherein the first damping mating part 131 is a first meshing gear tooth, and the second damping mating part 142 is a second meshing gear tooth, and the first meshing gear tooth and the second meshing gear tooth mesh.

[0077] In this embodiment, the radius of the first meshing tooth can be greater than the radius of the second meshing tooth; the radius of the first meshing tooth can be less than the radius of the second meshing tooth; the radius of the first meshing tooth can be equal to the radius of the second meshing tooth; this embodiment does not impose any limitations on this. In one possible implementation provided by this embodiment, the radius of the first meshing tooth is greater than the radius of the second meshing tooth.

[0078] The damped ultra-thin telescopic cable 1 provided in this application embodiment improves the reliability of the engagement between the first damping engagement part 131 and the second damping engagement part 142 by making the first damping engagement part 131 a first meshing tooth and the second damping engagement part 142 a second meshing tooth, with the first meshing tooth and the second meshing tooth meshing together.

[0079] Reference Figure 1 , Figure 2 , Figure 9 and Figure 10 This application provides a damped ultra-thin telescopic line 1, wherein the radius of the first meshing gear tooth is greater than the radius of the second meshing gear tooth.

[0080] The damped ultra-thin telescopic cable 1 provided in this application embodiment has a first meshing gear tooth radius larger than the second meshing gear tooth radius. The radius setting constitutes the physical requirement of a reduction gear, so that when the cable 11 is extended, the damping structure 14 does not generate resistance and does not obstruct the cable 11. When the cable 11 is shortened, the damping structure 14 generates resistance, so that the cable 11 decelerates when shortening.

[0081] This application provides a damped ultra-thin telescopic cable 1, which also includes a locking structure. The locking structure includes a first locking part 123 disposed on the housing 12 and a second locking part 1351 disposed on the winding structure 13. When the winding structure 13 rotates, the first locking part 123 and the second locking part 1351 cooperate to lock the cable 11.

[0082] In this embodiment of the application, when the winding structure 13 rotates, the first locking part 123 and the second locking part 1351 cooperate to lock the wire 11. Here, the wire 11 can be locked to a target length; for example, the wire 11 can be locked to 10 centimeters. At this time, when it is necessary to unlock the wire 11, the user can continue to stretch the wire 11 so that the first locking part 123 and the second locking part 1351 separate, and thus the wire 11 can be unlocked.

[0083] In this embodiment, the first locking part 123 can be a locking protrusion disposed within the receiving cavity, and the second locking part 1351 can be a locking groove disposed on the locking track 135 on the winding structure 13. When the winding structure 13 rotates, the locking protrusion engages with the locking groove to lock the wire 11. Alternatively, the first locking part 123 can be a locking groove disposed on the locking track 135 within the receiving cavity, and the second locking part 1351 can be a locking protrusion disposed on the winding structure 13. When the winding structure 13 rotates, the locking protrusion engages with the locking groove to lock the wire 11.

[0084] The damped ultra-thin telescopic cable 1 provided in this application embodiment has a first locking part 123 and a second locking part 1351 that cooperate to lock the cable 11 when the winding structure 13 rotates, so as to facilitate user use.
