[0008] In some embodiments, a positioning groove is formed on the positioning gear, and the positioning groove opens toward the direction of rotation of the wheel core; wherein the positioning rod is inserted into the positioning groove to limit the movement of the wheel core.

[0009] In some embodiments, a limiting portion is further provided on the positioning gear teeth. The limiting portion is located on a side of the positioning groove away from the wheel disc and extends along the direction of rotation of the wheel core.

[0010] In some embodiments, the positioning wheel further includes: an arcuate portion, which is arranged on the edge of the positioning wheel teeth away from the wheel disc and is concentric with the wheel disc; wherein the positioning rod and the reset rod are respectively in sliding contact with the arcuate portion to push the positioning member to swing back and forth as a whole.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] like Figure 1 and Figure 2As shown, an embodiment of the present invention provides a retractable data cable 1 that can extend the length of the data cable according to usage requirements and automatically retract the data cable. The retractable data cable 1 includes a housing 10, a wheel core 20, and a positioning member 30. The wheel core 20 is disposed within the housing 10 and can move relative to the housing 10. The wheel core 20 is provided with a positioning wheel 201. The positioning member 30 is movably connected to the housing 10 via a swing structure 40. The positioning member 30 abuts or separates from the positioning wheel 201 to control the movement of the wheel core 20. In other words, the retractable data cable 1 is provided with a positioning member 30 that can control the rotation of the wheel core 20. The positioning wheel 201 is disposed at one end of the wheel core 20, which is adjacent to the positioning member 30, along the axial extension direction. The positioning wheel 201 is fixedly connected to the wheel core 20. The data cable 50 is wound around the wheel core 20. When the data cable 50 is extended or retracted, it drives the wheel core 20 to rotate together. At this time, the positioning wheel 201 disposed on the wheel core 20 rotates with the wheel core 20. Specifically, when the data cable 50 is wound clockwise around the wheel core 20, pulling the data cable 50 outward from the housing 10 will cause the wheel core 20 to rotate clockwise. When the data cable 50 is retracted back into the housing 10, the wheel core 20 rotates counterclockwise. Conversely, when the data cable 50 is wound counterclockwise around the wheel core 20, pulling the data cable 50 outward from the housing 10 will cause the wheel core 20 to rotate counterclockwise. When the data cable 50 is retracted back into the housing 10, the wheel core 20 rotates clockwise.

[0028] Specifically, if Figure 2 As shown, the positioning wheel 201 and the positioning member 30 can cooperate, and during the rotation of the wheel core 20, the positioning member 30 swings along with the positioning wheel 201. Figure 2 When the wheel core 20 is in the non-positioning state, the positioning member 30 is separated from the positioning wheel 201, and the positioning wheel 201 can rotate without restriction, so that the wheel core 20 can rotate smoothly; when the positioning member 30 swings to the position shown in FIG. Figure 3 In the position shown, the wheel core 20 is in a positioning state, and the positioning member 30 is engaged with the positioning wheel 201, which restricts the positioning wheel 201 from rotating, thereby restricting the rotation of the wheel core 20 and fixing the length of the data cable 50 extending out of the housing 10.

[0029] like Figure 1 and Figure 2As shown, the positioning member 30 is provided with a first magnetic member 301, and the housing 10 is provided with a second magnetic member 101 and a third magnetic member 102 spaced apart at corresponding positions. The first magnetic member 301 cooperates with the second magnetic member 101 or the third magnetic member 102 to position the positioning member 30 relative to the swing position of the positioning wheel 201. It can be understood that when the positioning member 30 swings with the positioning wheel 201, the first magnetic member 301 provided on the positioning member 30 moves with the swing of the positioning member 30. The housing 10 is provided with a second magnetic member 101 and a third magnetic member 102. When the positioning member 30 moves to the position shown in FIG. Figure 2 When the first magnetic member 301 is in the position shown, the first magnetic member 301 is close to the second magnetic member 101. At this time, there is a mutual attraction between the first magnetic member 301 and the second magnetic member 101. Even if the positioning member 30 swings, it can only swing in a small range near the second magnetic member 101. That is, the second magnetic member 101 limits the positioning member 30 to the position shown. Figure 2 In the position shown, the positioning member 30 is difficult to abut against the positioning wheel 201, thereby achieving smooth rotation of the wheel core 20; when the positioning member 30 moves to the position shown Figure 3 When the first magnetic member 301 is in the position shown, the first magnetic member 301 is close to the third magnetic member 102. At this time, there is a mutual attraction between the first magnetic member 301 and the third magnetic member 102. The third magnetic member 102 limits the positioning member 30 to the position shown in FIG. Figure 3 In the position shown, the positioning member 30 is kept close to the positioning wheel 201 so that the positioning wheel 201 can abut against the positioning member 30 when rotating, thereby restricting the positioning wheel 201 from further rotating.

[0030] The present invention provides a retractable data cable comprising a housing, a wheel core, and a positioning member. The wheel core is disposed within the housing and is movable relative to the housing. A positioning wheel is provided on the wheel core. The positioning member is movably connected to the housing via a swing mechanism. The positioning member engages or disengages from the positioning wheel to control the movement of the wheel core. Among them, a first magnetic member is provided on the positioning member, and a second magnetic member and a third magnetic member are provided at intervals on the corresponding positions of the shell. The first magnetic member cooperates with the second magnetic member or the third magnetic member respectively to position the swing position of the positioning member relative to the positioning wheel. In this way, through the cooperation of the first magnetic member on the positioning member and the second magnetic member or the third magnetic member on the shell, the position of the positioning member can be limited, so that the cooperation between the positioning member and the positioning wheel has two different working states, thereby controlling the rotation and positioning of the wheel core, thereby achieving the fixation of the length of the data cable extending out of the shell, simplifying the positioning member structure, making the positioning function easy to realize, and ensuring the reliability of the positioning function of the telescopic data cable. At the same time, the simplified positioning member structure can reduce the space occupied inside the shell, which is conducive to reducing the overall size of the telescopic data cable, making it easy to carry, and giving users a good sense of use.

[0031] In some embodiments, as Figure 3 and Figure 4 As shown, the positioning member 30 includes a body 302, a positioning rod 303, and a reset rod 304. The body 302 is mounted on the inner wall of the housing 10 via a swing structure 40. The positioning rod 303 is connected to the body 302 and is used to at least abut against the positioning wheel 201 to limit the position. The reset rod 304 is connected to the body 302 and is spaced apart from the positioning rod 303. The reset rod 304 is used to cooperate with the positioning wheel 201 to push the positioning rod 303 into abutment with the positioning wheel 201. The positioning wheel 201 is at least partially located between the positioning rod 303 and the reset rod 304, and the first magnetic member 301 is disposed on the positioning rod 303.

[0032] It can be understood that when the data cable 50 is wound around the wheel core 20 in a clockwise direction, the main body 302 of the positioning member 30 has a positioning rod 303 and a reset rod 304 arranged at intervals, and the positioning wheel 201 is arranged between the positioning rod 303 and the reset rod 304. When the data cable 50 is stretched outward, it drives the wheel core 20 to rotate in the clockwise direction. At this time, the positioning wheel 201 rotates together with the wheel core 20. The positioning wheel 201 can cooperate with the positioning rod 303 and the reset rod 304 respectively. When the positioning rod 303 cooperates with the positioning wheel 201, the positioning wheel 201 is restricted from rotating; Figure 2 and Figure 4 As shown, when the reset rod 304 cooperates with the positioning wheel 201, the positioning wheel 201 pushes the reset rod 304, and the reset rod 304 drives the positioning member 30 to swing, so that the positioning rod 303 approaches the positioning wheel 201 to achieve switching from the non-positioning state to the positioning state.

[0033] When the data cable 50 is wound counterclockwise around the wheel core 20, the functions of the positioning rod 303 and the reset rod 304 are swapped. At this time, the reset rod 304 cooperates with the positioning wheel 201 for positioning during the rotation of the wheel core 20, and pushes the positioning rod 303 during the forward rotation of the wheel core 20, and the positioning member 30 is driven by the positioning rod 303 to swing.

[0034] Specifically, the first magnetic member 301 may be provided on the positioning rod 303 , and the position of the positioning rod 303 may be limited by the magnetic attraction between the first magnetic member 301 and the second magnetic member 101 or the third magnetic member 102 .

[0035] It should be noted that the first magnetic member 301 is arranged on the positioning rod 303 for only an exemplary arrangement. The first magnetic member 301 can also be arranged on the reset rod 304 or the body 302. As long as the positioning member 30 can be positioned, no further restrictions are made here.

[0036] In the embodiment of the present utility model, a positioning rod and a reset rod are arranged at intervals on the main body of the positioning member, and the positioning state switching of the wheel core is realized through the cooperation between the positioning rod and the positioning wheel. Under the action of the reset rod, the positioning rod can smoothly approach the positioning wheel to realize positioning. Under the coordinated movement of the positioning rod and the reset rod, the non-positioning state and the positioning state of the wheel core are switched with each other, thereby ensuring the normal operation of the wheel core, enabling the length positioning function of the data cable to be smoothly realized, improving the reliability of the realization of the retractable data cable function, and improving the user experience.

[0037] In some embodiments, as Figure 5 As shown, the positioning wheel 201 includes a wheel disc 2010 and positioning gear teeth 2011. The wheel disc 2010 is coaxially arranged with the wheel core 20 and rotates with the wheel core 20. It can be understood that the outer edge of the wheel disc 2010 of the positioning wheel 201 is provided with positioning gear teeth 2011. The wheel disc 2010 is fixed to the wheel core 20 and is coaxial with the wheel core 20. The wheel disc 2010 rotates with the rotation of the wheel core 20, thereby driving the positioning wheel 2011 to rotate.

[0038] like Figure 3 As shown, the positioning gear teeth 2011 are used to abut against the positioning rod 303 to limit the position. At least two positioning gear teeth 2011 are provided, and each positioning gear tooth 2011 is spaced apart along the circumference of the wheel disc 2010. In other words, the wheel disc 2010 of the positioning wheel 201 is provided with at least two positioning gear teeth 2011, and the positioning gear teeth 2011 are spaced apart along the circumference of the wheel disc 2010. During one rotation of the wheel core 20, the positioning rod 303 can abut against the positioning gear teeth 2011 at least twice. That is, during one rotation of the wheel core 20, the wheel core 20 can be positioned at least twice, thereby improving the accuracy of the length adjustment of the data cable 50.

[0039] The embodiment of the utility model limits the rotation of the wheel core through the cooperation of the positioning gear teeth and the positioning rod, reduces the complexity of the cooperation structure of the positioning part and the positioning wheel, and facilitates production and assembly. At the same time, at least two positioning gear teeth are provided, so that the wheel core can be positioned at least twice during one rotation, thereby improving the accuracy of the data cable length adjustment and improving the user experience.

[0040] In some embodiments, as Figure 3 and 5As shown, the positioning gear 2011 is provided with a positioning groove 2012, which opens in the direction of rotation of the wheel core 20. A positioning rod 303 is inserted into the positioning groove 2012 to limit the movement of the wheel core 20. It is understood that the positioning gear 2011 is provided with a positioning groove 2012 that opens in the direction of rotation of the wheel core 20. During rotation, the positioning groove 2012 approaches the positioning rod 303, causing the positioning rod 303 to gradually abut against the bottom of the positioning groove 2012, thereby locking the wheel core 20 in rotation. Alternatively, by matching the contours of the abutting portions of the positioning rod 303 and the positioning groove 2012, the positioning rod 303 can be aligned with the positioning groove 2012, forming a stable abutment state, thereby limiting the wheel core 20 from continuing to rotate.

[0041] The embodiment of the utility model provides a positioning groove, so that the positioning rod can be inserted into the bottom of the positioning groove in the positioning state, forming a stable fit state, ensuring the stability of the wheel core positioning state, avoiding failure of the positioning function, and improving the user experience.

[0042] In some embodiments, as Figure 5 As shown, the positioning gear 2011 is further provided with a limiting portion 2013, which is located on the side of the positioning groove 2012 away from the wheel disc 2010 and extends along the direction of rotation of the wheel core 20. It can be understood that the limiting portion 2013 is provided at the opening of the positioning groove 2012, on the side of the positioning groove 2012 away from the wheel disc 2010, and extends along the edge of the positioning gear 2011 in the direction of rotation of the positioning gear 2011, thereby increasing the depth of the positioning groove 2012. Figure 3 As shown, when the positioning rod 303 is inserted into the positioning groove 2012, the limiting portion 2013 is located on the outside of the positioning rod 303, preventing the positioning rod 303 from detaching from the positioning groove 2012, so that the positioning groove 2012 and the positioning rod 303 can be stably matched, thereby improving the reliability when limiting the rotation of the wheel core 20.

[0043] In this embodiment of the utility model, a limiting portion is provided on the positioning gear. The limiting portion further limits the cooperation between the positioning groove and the positioning rod, thereby improving the stability of the abutment between the positioning groove and the positioning rod and optimizing the performance of the product. At the same time, the limiting portion is provided on the positioning gear, which can achieve stable abutment between the positioning rod and the positioning groove without the need for additional parts, simplifying the structure of the positioning gear and facilitating production and assembly.

[0044] In some embodiments, as Figure 5 As shown, the positioning wheel 201 further includes an arcuate portion 2014. The arcuate portion 2014 is arranged on the edge of the positioning gear 2011 away from the wheel disc 2010 and is coaxial with the wheel disc 2010. Figure 2As shown, the positioning rod 303 and the reset rod 304 are respectively in sliding contact with the arcuate portion 2014 to push the positioning member 30 to swing back and forth as a whole. It can be understood that the outer side of the positioning gear 2011 is the arcuate portion 2014, and the edge shape of the arcuate portion 2014 is concentric with the wheel disc 2010. During the rotation of the wheel core 20, the arcuate portion 2014 rotates with the wheel disc 2010. At this time, the edges of the positioning rod 303 and the reset rod 304 on one side are tangent to the arcuate portion 2014, and they rotate smoothly along the arcuate portion 2014, allowing the wheel core 20 to rotate smoothly in the non-positioned state without being affected by the protruding positioning gear teeth 2011. During the rotation, the positioning member 30 is pushed to swing back and forth to achieve the switching of the working state of the retractable data cable.

[0045] The embodiment of the utility model provides an arc portion on the positioning gear teeth, so that when the wheel core is in a non-positioning state, the positioning member can rotate normally along the arc portion without jamming. The user has a good feel when stretching the data cable, thereby improving the user's usage experience.

[0046] In some embodiments, as Figure 5 As shown, a protrusion 2015 is provided on the end of the positioning gear 2011 opposite to the positioning groove 2012. Figure 2 As shown, a step is formed between the protrusion 2015 and the wheel disc 2010 for pushing the positioning rod 303 or the reset rod 304 to move, and the protrusion 2015 is smoothly connected to the outer edge of the arc-shaped portion 2014. It can be understood that the positioning gear 2011 is provided with a protrusion 2015, which is located between the arc-shaped portion 2014 and the wheel disc 2010. The edge of the protrusion 2015 is a smooth arc and smoothly connected to the arc-shaped portion 2014. The protrusion 2015 forms a step between the arc-shaped portion 2014 and the wheel disc 2010. When the positioning rod 303 or the reset rod 304 abuts the arc-shaped portion 2014, the positioning rod 303 or the reset rod 304 can be pushed away from the wheel disc 2010 by the step and slide along the protrusion 2015 to the arc-shaped portion 2014, thereby promoting the swing of the positioning member, thereby achieving the switching between the positioning and non-positioning states of the wheel core.

[0047] Specifically, when the data cable 50 continues to stretch outward, the wheel core 20 rotates forward. During the forward rotation of the wheel core 20, the reset rod 304 first abuts against the raised portion 2015, then slides along the raised portion 2015 to the arc portion 2014 and continues to slide. The positioning gear 2011 pushes the reset rod 2015 away from the wheel disc 2010, driving the positioning rod 303 to abut against the wheel disc 2010. When the positioning gear 2011 rotates to the positioning rod 303, the positioning rod 303 slides along the arc portion 2014, and the positioning gear 2011 pushes the positioning rod 303 away from the wheel disc 2010. The reset rod 304 swings back to the position abutting against the wheel disc 2010 until the wheel core 20 rotates to the next positioning gear tooth 2011 abuts against the reset rod 304, and the above movement is repeated. During the stretching process of the data cable 50, the positioning member 30 swings back and forth on both sides of the positioning wheel 201 without interfering with the forward rotation of the wheel core 20, ensuring smooth stretching of the data cable 50. After the data cable 50 is stretched to the desired length, the tension applied to the data cable 50 disappears, and the wheel core 20 reverses, pushing the reset rod 304 via the positioning gear 2011, allowing the positioning rod 303 to return to the position close to the wheel disc 2010, thereby causing the positioning rod 303 to abut against the positioning groove 2012, thus locking the wheel core 20 in rotation and fixing the length of the data cable 50.

[0048] The embodiment of the utility model provides a raised portion smoothly connected to the arc portion to prevent the occurrence of jamming during rotation, which affects the normal extension and retraction of the data cable. At the same time, a step is formed between the arc portion and the positioning gear teeth, so that the positioning gear teeth can push the positioning member to swing. The positioning member can be driven to swing by the rotation of the wheel core itself, without the need for an additional driving device, simplifying the structure, and helping to reduce the size of the retractable data cable, making it easy to carry and providing a good user experience.

[0049] In some embodiments, as Figure 2 and Figure 3As shown, the swing structure 40 includes a through-hole 401 and a fixed post 402. The through-hole 401 is provided in one of the housing 10 and the body 302; the fixed post 402 is provided in the other of the housing 10 and the body 302. The fixed post 402 is movably disposed within the through-hole 401. It is understood that the positioning member 30 is mounted on the inner wall of the housing 10 via the swing structure 40. The swing structure 40 includes a through-hole 401 and a fixed post 402, which is disposed within the through-hole 401. The body 302 of the positioning member 30 can swing about the fixed post 402, thereby achieving the swinging of the positioning rod 303 or the reset rod 304. Specifically, the through-hole 401 can be provided in the body 302, in which case the fixed post 402 is disposed on the inner wall of the housing 10; or the through-hole 401 can be provided in the inner wall of the housing 10, in which case the fixed post 402 is disposed on the body 302. Any method is suitable as long as the positioning member 30 can be swingably mounted on the inner wall of the housing 10.

[0050] The embodiment of the utility model sets the swing structure as a combination of a through hole and a fixed column, so that the positioning member can swing around the fixed column, thereby achieving abutment or separation between the positioning member and the positioning wheel. The structure is simple and easy to disassemble and repair.

[0051] In some embodiments, as Figure 3 and Figure 4 As shown, the through hole 401 is a long waist hole. The fixing post 402 reciprocates in the through hole 401 to make the positioning member 30 swing and switch the positioning and non-positioning states of the retractable data cable 1. It can be understood that the through hole 401 is set as a long waist hole. When the positioning member 30 swings, the fixing post 402 can reciprocate along the length direction of the through hole 401. Figure 2 As shown, when the positioning member 30 is separated from the positioning wheel 201, the fixing column 402 is located at one end of the through hole 401. At this time, the positioning rod 303 swings to a position away from the positioning gear 201 and also maintains a certain distance in the diameter direction of the positioning wheel 201 to avoid the positioning rod 303 from abutting against the positioning wheel 201; Figure 3 As shown, when the positioning rod 303 abuts against the positioning groove 2012, the fixing column 402 moves to the other end of the through hole 401, and the positioning rod 303 swings to a position close to the positioning wheel 201, and is also close to the positioning wheel 201 in the diameter direction of the positioning wheel 201, so as to facilitate the abutment of the positioning rod 303 against the positioning wheel 201.

[0052] The embodiment of the utility model sets the through hole as a long waist hole, so that the swing range of the positioning member is larger, ensuring the abutment and separation of the positioning member and the positioning wheel, improving the reliability of the positioning and non-positioning functions of the telescopic data cable, and optimizing the performance of the product.

[0053] In some embodiments, as Figure 1 and Figure 2As shown, the retractable data cable 1 further includes a data cable 50 and an opening 60. The data cable 50 is wound on the wheel core 20 and can be unfolded and extended out of the housing 10; the opening 60 is opened on the housing 10 for the data cable 50 to extend out. It can be understood that the data cable 50 is wound on the wheel core 20 and stored inside the shell 10. One end of the data cable 50 extends out of the opening 60 on the shell 10. The user can pull the data cable 50 out of the shell 10 by stretching the end of the data cable 50 extending out of the opening 60. At this time, the wheel core 20 can rotate smoothly in the positive direction, and the positioning rod 303 is separated from the positioning wheel 201; when the user stretches out the data cable 50 of the required length, release the data cable 50, and the wheel core 50 rotates driven by the spring. At this time, the positioning rod 303 approaches the positioning wheel 201 and abuts against the positioning wheel 201, thereby limiting the wheel core 20 from continuing to rotate, thereby fixing the length of the data cable 50 stretched out of the shell 10, and the switching of the retractable data cable between the positioning state and the non-positioning state can be achieved through the cooperation of a simple positioning member and a positioning wheel.

[0054] The retractable data cable in the embodiment of the present invention can be positioned by simply cooperating with a positioning member and a positioning wheel, which simplifies the positioning structure and reduces the size of the positioning member in the thickness direction, which is conducive to reducing the size of the product, making it easier for users to carry it when going out and providing users with a good user experience.

[0055] 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.
