[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

In order to avoid unnecessary repetition, the various possible combinations of the specific technical features in the utility model will not be described separately.
[0027] In the following description, the terms "first\second\..." are only used to distinguish different objects, and do not mean that the objects have the same or related points. It should be understood that the directions "above", "below", "outside" and "inside" are all directions in normal use, and the directions "left" and "right" refer to the left and right directions shown in the corresponding schematic diagrams, which may or may not be the left and right directions in normal use.
[0028] It should be noted that the terms "comprises", "includes" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element. "Multiple" means greater than or equal to two.
[0029] like Figure 1-3 As shown, a retractable data cable provided by an embodiment of the utility model includes a housing 1, a winding mechanism 2, a cable body 3 and a connector 31. The cable body 3 is used to connect to an external device (not shown) to achieve data transmission and / or charging, and the cable body 3 includes at least two tensile wires 32. The connector 31 is used to connect to the interface of the external device, and the cable body 3 is connected to the connector 31, and the cable body 3 is connected to the external device through the connector 31. The housing 1 is formed with an installation cavity 15 (refer to Figure 6 ), an outlet 14 is provided on the housing 1, and the outlet 14 is communicated with the installation cavity 15, the winding mechanism 2 is provided in the installation cavity 15, the wire body 3 is connected to the winding mechanism 2, and extends out through the outlet 14, so that the connector 31 is located outside the housing 1. It can be understood that the two ends of the wire body 3 can extend out of the housing 1 through the same outlet 14, or each can extend out of the housing 1 through an outlet 14. Specifically, the winding mechanism 2 can be elastically deformed by force to generate a driving force, and the wire body 3 is connected to the winding mechanism 2 to drive the wire body 3 to automatically reel. When it is needed to use, the wire body 3 wound on the winding mechanism 2 can be pulled out of the housing 1 by pulling the connector 31, and the length of the wire body 3 becomes longer to meet the use requirements; when the wire body 3 is used, the winding mechanism 2 itself generates a driving force to pull the wire body 3 into the housing 1, so as to realize the automatic storage of the wire body 3, thereby avoiding the inconvenience caused by the long wire body 3 outside the housing 1 when it is not needed. Furthermore, the wire body 3 includes at least two tensile wires 32 . The tensile wires 32 have strong tensile strength and will not break even after multiple bending or folding, thereby improving the tensile strength of the wire body 3 .
[0030] In some possible implementation schemes, the connector 31 of the utility model embodiment may be a TYPE-C connector or a USB Type-A connector, or other types of connectors. Those skilled in the art may adjust the type of the connector 31 according to the interface type of the external device. It should be noted that both ends of the wire body 3 may be connected to the connector 31, or one of them may be connected to the connector 31. Moreover, the types of the connectors 31 at both ends of the wire body 3 may be the same or different.
[0031] In the embodiment of the utility model, the wire body 3 is rolled up by the winding mechanism 2, so as to improve the utilization rate of the internal space of the shell 1. The wire body 3 is fixedly connected to the winding mechanism 2 and extends out through the outlet 14, so that the connector 31 is located outside the shell 1, and the wire body 3 can be pulled out of the shell 1 by pulling the connector 31, so that the wire body 3 can be easily pulled out of the shell 1. Specifically, the maximum cross-sectional area of at least part of the position of the connector 31 is greater than the cross-sectional area of the outlet 14, so that the connector 31 cannot pass through the outlet 14, thereby preventing the connector 31 from being pulled into the shell 1 by the winding mechanism 2. It should be noted that the above-mentioned maximum cross-sectional area is the maximum area of the cross section of the outer contour of the connector 31 perpendicular to the central axis of the wire body 3.
[0032] The working mode of the winding mechanism 2 of the embodiment of the utility model determines that the retractable data cable will be subjected to tension and frequently pulled out and pulled into the housing 1 when in use. In addition, the wire body 3 is stored in the housing 1 in the storage state and is curled and wound on the winding mechanism 2. The above-mentioned curling and winding storage method will cause deformation of the wire body 3. The wire body 3 is in the storage state for a long time, which greatly increases the probability of damage to the wire body 3. The embodiment of the utility model improves the overall tensile performance of the wire body 3 by providing a tensile wire 32 with high tensile strength, reduces the risk of failure of the wire body 3 in the working mode that requires frequent pulling and curling, thereby improving the working performance and service life of the retractable data cable.
[0033] It is understandable that one or more wire bodies 3 of the embodiment of the utility model can be provided. When multiple wire bodies 3 are provided, multiple wire bodies 3 are wound on the winding mechanism 2 from the inside to the outside, and multiple wire bodies 3 are fixedly connected to the winding mechanism 2. Among them, the parts of two adjacent wire bodies 3 wound on the winding mechanism 2 are tightly fitted to improve the utilization rate of the internal space of the housing 1. One wire body 3 can only realize the charging of one external device, or realize the data transmission between two external devices with a specific type of interface, so that the use of the telescopic data cable is greatly limited. In some possible embodiments, multiple wire bodies 3 are provided, and by adjusting the type of connector 31 on different wire bodies 3, a telescopic data cable can be realized to realize the charging of external devices with different types of interfaces, or realize the data transmission between two external devices with various types of interfaces. This embodiment can greatly enrich the application scenarios of the telescopic data cable by setting multiple wire bodies 3.
[0034] The retractable data cable provided by the embodiment of the utility model is provided with a winding mechanism 2, the wire body 3 is connected to the winding mechanism 2, and the housing 1 is provided so that the winding mechanism 2 can be located inside the housing 1, and the connector 31 on the wire body 3 is located outside the housing 1. In this way, in the storage state, the wire body 3 is stored in the housing 1 and rolled up on the winding mechanism 2, which not only completes the storage of the wire body 3, but also improves the utilization rate of the internal space of the housing 1. In the use state, the wire body 3 can be pulled out of the housing 1 until the length of the wire body 3 pulled out of the housing 1 meets the use requirements. When the wire body 3 is pulled out, the winding mechanism 2 is elastically deformed, so that when the wire body 3 is used, the winding mechanism 2 generates a driving force to pull the wire body 3 into the housing 1, so that the wire body 3 is automatically rolled up. In addition, the wire body 3 includes at least two tensile wires 32, and the tensile wires 32 have a strong tensile strength, and will not break under frequent bending or bending, thereby improving the tensile strength of the wire body 3.
[0035] In some embodiments, Figure 3 As shown, the tensile conductor 32 includes a twisted pair 322 and a tensile shielding sleeve 321, and the tensile shielding sleeve 321 is sleeved on the twisted pair 322. Among them, the twisted pair 322 has at least two twisted wires arranged in parallel or spirally wound with each other. As the most easily damaged component during the bending process, the shielding layer is easily broken during repeated pulling and curling, thereby causing shielding failure. The material of the tensile shielding sleeve 321 of the embodiment of the utility model is graphene, and the tensile shielding sleeve 321 made of graphene has strong toughness and high tensile strength. Even if the wire body 3 is bent and wound on the winding mechanism 2 for a long time and is frequently pulled, the risk of the tensile shielding sleeve 321 breaking is not high, which can effectively ensure the shielding function. In addition, the tensile strength of the shielding layer of the tensile conductor 32 is improved by setting the tensile shielding sleeve 321, thereby improving the service life of the wire body 3.
[0036] In some embodiments, Figure 3 As shown, the line body 3 also includes a signal line 35, a power line 34 and a sheath 33, and the power line 34, the signal line 35 and the tensile wire 32 are all arranged in the sheath 33. The power line 34 and the signal line 35 are located between the two tensile wires 32, and the two tensile wires 32 with high tensile strength are arranged at the outermost side of the line body 3 where damage is most likely to occur, thereby improving the overall strength of the line body 3. Among them, along the first direction, a tensile wire 32, a power line 34, three signal lines 35, a power line 34 and a tensile wire 32 are arranged in a row in sequence. It should be noted that the first direction is Figure 2 In the direction shown by A1 in FIG, when the wire body 3 is connected to the winding mechanism 2, the first direction is parallel to the rotation axis of the winding mechanism 2.
[0037] In the embodiment of the utility model, on the one hand, by arranging the power line 34, the signal line 35 and the two tensile wires 32 in a row, the cross section of the wire body 3 perpendicular to the central axis of the wire body 3 forms a flat structure with a small thickness and a large width. The flat structure makes the multi-layer structure formed by the wire body 3 being curled on the winding mechanism 2 have strong stability, and prevents the wire bodies 3 of different layers in the above-mentioned multi-layer structure from moving axially along the rotating shaft 111 and thus being misaligned. On the other hand, the side of the sheath 33 facing the winding mechanism 2 is defined as the pressure surface 331, and the side of the sheath 33 opposite to the pressure surface 331 is defined as the tension surface 332. The distances from the center plane on the wire body 3 to the pressure surface 331 and the tension surface 332 are defined to be equal. It can be understood that the farther the position on the wire body 3 is from the center plane, the greater the deformation amount is, and the greater the probability of damage is. The above-mentioned flat structure of this embodiment can not only make the distance from the pressure surface 331 and the tension surface 332 to the center plane smaller, thereby improving the overall strength of the line body 3; it can also make the distance from any part of the power line 34, the signal line 35 and the two tensile wires 32 to the center plane smaller, thereby reducing the probability of damage to the power line 34, the signal line 35 and the two tensile wires 32.
[0038] In some possible implementations, the central axes of the power line 34, the signal line 35 and the two tensile wires 32 are all located in the central plane, which can minimize the distance from the pressure surface 331 and the tension surface 332 to the central plane; and can also minimize the distance from any part of the power line 34, the signal line 35 and the two tensile wires 32 to the central plane. Not only the deformation of the power line 34, the signal line 35 and the two tensile wires 32 is minimized, but also the deformation of the sheath 33 is minimized, so that the overall strength of the wire body 3 is higher, thereby increasing the service life of the wire body 3.
[0039] In some embodiments, Figure 4 and Figure 5As shown, the winding mechanism 2 includes a wheel core 21 and a mainspring 22. The wheel core 21 is rotatably connected to the housing 1. The wheel core 21 includes a bottom plate 215 and a protrusion 216. A receiving cavity 217 for receiving the mainspring 22 is provided in the wheel core 21. A plurality of protrusions 216 are circumferentially provided on the bottom plate 215 of the wheel core 21. The inner side walls of the bottom plate 215 and the plurality of protrusions 216 enclose the receiving cavity 217. The mainspring 22 is installed in the receiving cavity 217. One end of the mainspring 22 is fixedly connected to the wheel core 21, and the other end is fixedly connected to the housing 1. Among them, the wire body 3 is fixedly connected to the wheel core 21, so that the wire body 3 can drive the wheel core 21 to rotate, and the wheel core 21 can drive the wire body 3 to be reeled on the wheel core 21. When using a retractable data cable, pull the connector 31 outward to pull out the wire body 3. The wire body 3 drives the wheel core 21 to rotate along a second direction, and the second direction is Figure 4 The spring 22 is tightened in the direction shown by A2 in FIG. When the cable 3 is pulled out to a suitable length, the connector 31 on the cable 3 is connected to an external device. When the retractable data cable is used up and the cable 3 needs to be stored, the spring 22 stretches and drives the wheel core 21 to rotate along the third direction. The third direction is Figure 4 The second direction is opposite to the third direction as shown by A3 in the figure, so that the wheel core 21 drives the wire body 3 to move into the housing 1, and the wire body 3 is curled and wound on the wheel core 21, so that the wire body 3 is rolled up.
[0040] In some embodiments, Figure 2 As shown, a rotating shaft 111 is provided on the housing 1, and when the line body 3 is connected to the wheel core 21, the first direction is parallel to the axial direction of the rotating shaft 111. A mounting hole 218 is provided on the wheel core 21, and the rotating shaft 111 is penetrated in the mounting hole 218, so that the wheel core 21 is rotatably connected to the rotating shaft 111 on the housing 1 through the mounting hole 218.
[0041] In some embodiments, Figure 2 and Figure 4 As shown, a fixing protrusion 211 is provided on the wheel core 21, and a fixing groove 1111 is provided on the side wall of the rotating shaft 111. One end of the mainspring 22 is inserted into the fixing groove 1111 so that the mainspring 22 is fixedly connected to the fixing groove 1111, and the other end is clamped on the fixing protrusion 211.
[0042] In some possible implementations, the rotating shaft 111 includes two semi-cylinders 1112, and the semi-cylinders 1112 include arc surfaces and side planes. The two semi-cylinders 1112 are fixed to the inner wall of the housing 1, and the side planes of the two semi-cylinders 1112 are relatively spaced apart so that a fixing groove 1111 is formed between the two side planes. The arc surfaces of the two semi-cylinders 1112 are located on the same cylindrical surface, so that the two semi-cylinders 1112 are combined to form the rotating shaft 111, which can be rotatably connected in the mounting hole 218.
[0043] In some embodiments, Figure 4 and Figure 5 As shown, a mounting groove 212 matching the wire body 3 is provided on the wheel core 21 along the circumference, and the mounting groove 212 is located outside the accommodating cavity 217. Two passage openings 213 are also provided on the edge of the wheel core 21. The two passage openings 213 are respectively connected to the two ends of the mounting groove 212. The wire body 3 is clamped in the mounting groove 212, and the two ends of the wire body 3 pass through the two passage openings 213 respectively. It can be understood that both ends of the wire body 3 are wound around the wheel core 21 along the second direction. The two passage openings 213 of the embodiment of the utility model are respectively the first passage opening 2131 and the second passage opening 2132. The wire body 3 extends out of the first passage opening 2131 along the second direction, and the wire body 3 extends out of the second passage opening 2132 along the third direction. A limiting protrusion 214 is provided between the mounting groove 212 and the second channel opening 2132. The limiting protrusion 214 is provided on the outside of the accommodating cavity 217. The wire body 3 is provided on the outside of the limiting protrusion 214 to limit the end of the wire body 3 extending out of the second channel opening 2132 from moving toward the accommodating cavity 217, thereby avoiding the end of the wire body 3 extending out of the second channel opening 2132 from interfering with the mainspring 22 in the accommodating cavity 217, thereby avoiding interference with the mainspring 22.
[0044] In some embodiments, Figure 2 As shown, the housing 1 includes a first housing 11 and a second housing 12, the first housing 11 and the second housing 12 are fixedly connected and enclosed to form a mounting cavity 15 (refer to Figure 6 ). The rotating shaft 111 of this embodiment is arranged on the first shell 11. It can be understood that the rotating shaft 111 and the first shell 11 can be manufactured and formed as one piece; the rotating shaft 111 and the first shell 11 can also be two independent components, and the rotating shaft 111 is fixedly connected to the inner wall of the first shell 11. The mainspring 22 is inserted into the end of the rotating shaft 111 close to the first shell 11, and a threaded hole is provided on the end face of the rotating shaft 111 away from the first shell 11. A through hole is provided on the second shell 12, and screws for connecting the first shell 11 with the second shell 12 are inserted in the through hole and the threaded hole. The connection method of connecting the first shell 11 and the second shell 12 by screws is convenient for installation and disassembly, maintenance, installation or replacement of the wire body 3 and the mainspring 22. Based on the above, the rotating shaft 111 of this embodiment can be used to fix the mainspring 22, and can also be used for the rotational connection between the wheel core 21 and the shell 1, and can also be used to realize the connection between the first shell 11 and the second shell 12. In summary, the mainspring 22 , the first housing 11 , the second housing 12 , the wheel core 21 and the rotating shaft 111 of the embodiment of the utility model are a complete technical solution for optimizing the space design inside the housing 1 and improving the utilization rate of the internal space of the entire housing 1 .
[0045] It should be noted that, in addition to the above-mentioned screws, other connecting members may be provided between the first shell 11 and the second shell 12. Furthermore, the connection method between the first shell 11 and the second shell 12 of this embodiment is not limited to threaded connection. In other embodiments, the connection method between the first shell 11 and the second shell 12 may also be a snap connection, or a combination of a snap connection and a threaded connection.
[0046] In some embodiments, Figure 2 As shown, the housing 1 further includes a mounting member 13, which is disposed on the side wall of the second housing 12. The mounting member 13 is provided with a receiving groove 134 that matches the connector 31, so that the connector 31 can be received in the receiving groove 134. The outlet 14 is provided on the mounting member and is located at the bottom of the receiving groove 134. The mounting member 13 and the second housing 12 are detachably connected. It is understandable that the connection between the mounting member 13 and the second housing 12 can be threaded connection, clamping or other connection methods, or a combination of threaded connection and clamping.
[0047] In this embodiment, the receiving groove 134 is provided to receive the connector 31. When those skilled in the art set different types of connectors 31 on the line body 3 according to different external devices, it is also necessary to set receiving grooves 134 and / or outlets 14 of different shapes and sizes. In this embodiment, the receiving groove 134 is provided on the mounting member 13, and the mounting member 13 is detachably provided on the second housing 12. In this embodiment, the receiving groove 134 and / or outlet 14 can be replaced by replacing the mounting member 13.
[0048] In some embodiments, Figure 2 As shown, a first magnetic member 131 is provided on the mounting member 13, and the first magnetic member 131 is located at the bottom of the receiving groove 134. Specifically, a receiving groove 132 matching the first magnetic member 131 is provided on the mounting member 13, and the receiving groove 132 is located at the bottom of the receiving groove 134, and the first magnetic member 131 is installed in the receiving groove 132. A top plate 133 is provided in the mounting member 13, and the top plate 133 encapsulates the first magnetic member 131 in the receiving groove 132. A second magnetic member matching the first magnetic member 131 is provided in the connector 31, so that the connector 31 can be adsorbed in the receiving groove 134. When the telescopic data cable is idle, the connector 31 is adsorbed on the first magnetic member 131 in the receiving groove 134 through the second magnetic member, thereby realizing the storage and fixation of the connector 31 when the telescopic data cable is idle. This prevents the unfixed connector 31 from being accidentally pulled out when the retractable data cable is in the stored state, thereby causing inconvenience to the storage of the cable body 3 .
[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
