[0025] Referring to FIGS. 1 to 9, a data line according to an embodiment of the present application will be exemplarily described. The data line includes a case 100, a turntable, a connection line 300, a coil spring 410, and a position limiting assembly.
[0026] Inside the case 100, there is an accommodation space for accommodating the turntable, the coil spring 410, and the position limiting assembly. As shown in FIG. 2, in the embodiment of the present application, the case 100 includes a bottom case 110 that is fixed or removably connected and an upper cover 121, and the accommodation space is formed between the bottom case 110 and the upper cover 121. The upper cover 121 includes an upper cover 121 main body and a first connection plate 122. The upper cover 121 main body and the bottom case 110 are fixedly connected by an adhesive method or removably connected by screws. The first connection plate 122 is located on the side facing the bottom case 110 of the upper cover 121 main body and may be fixed to the upper cover 121 main body by an adhesive or screw connection method. A plurality of elastic conductive members 123 are installed on the side of the first connection plate 122 facing the bottom case 110. In some other embodiments, the first connection plate 122 may not be installed on the case 100, and a plurality of elastic conductive members 123 may be directly installed on the side of the upper cover 121 main body facing the bottom case 110.
[0027] The turntable is rotatably installed in the accommodation space and is configured to be rotatable along a first direction and a second direction opposite to the first direction. The first direction and the second direction may be the clockwise direction and the counterclockwise direction in FIG. 5, respectively. As shown in FIG. 2, in the embodiment of the present application, a rotating shaft 111 is installed at the central portion of the case 100. The turntable includes a turntable body 210 and a second connection plate 220. The second connection plate 220 is fixed to the side facing the upper cover 121 of the turntable body 210 by means of adhesion or screw connection. A shaft hole that fits with the rotating shaft 111 is installed at the central portions of the turntable body 210 and the second connection plate 220. The rotating shaft 111 is inserted through the shaft hole, and the turntable can rotate in the clockwise direction and the counterclockwise direction around the rotating shaft 111.
[0028] As shown in FIG. 2, in the embodiment of the present application, the connection line 300 includes a first wire harness 310, a second wire harness 320, a first connection connector 330, and a second connection connector 340. The first connection connector 330 and the second connection connector 340 are located outside the case 100 and may be a USB connector, a TYPE-C connector, a Lightning connector, etc., and those skilled in the art may arrange them as needed. Both ends of the first wire harness 310 are respectively connected to the first connection connector 330 and the case 100, and both ends of the second wire harness 320 are respectively connected to the second connection connector 340 and the turntable. The case 100 is provided with wire through holes corresponding to the first wire harness 310 and the second wire harness 320. The first wire harness 310 and the second wire harness 320 are respectively passed through the corresponding wire through holes, and the first wire harness 310 and the second wire harness 320 are conductively connected. Specifically, one end of the first wire harness 310 away from the first connection connector 330 is connected to the first connection plate 122 by a method such as welding and is conductively connected to a plurality of elastic conductive members 123. The first wire harness 310 includes a plurality of wire cores, and each wire core is connected to one elastic conductive member 123. The elastic conductive member 123 may be a metal dome, a pogo pin, or other suitable conductive elastic member. The turntable body 210 is provided with a wire through hole 213. One end of the second wire harness 320 away from the second connection connector 340 passes through the wire through hole 213 and is connected to the second connection plate 220 by a method such as welding. The second connection plate 220 is provided with a plurality of coaxial annular conductive parts 221 whose central axis coincides with the central axis of the rotation shaft 111 of the bottom case 110. The second wire harness 320 is conductively connected to the plurality of annular conductive parts 221. The second wire harness 320 includes a plurality of wire cores, and each wire core is connected to one annular conductive part 221. The annular conductive part 221 may be an annular copper sheet or other annular conductive metal sheet.In the process of the rotating disk rotating, the plurality of elastic conductive members 123 are always in contact with the plurality of annular conductive parts 221 respectively. In this way, the first wire harness 310 and the second wire harness 320 always maintain conductive connection through the elastic conductive members 123 and the annular conductive parts 221 in the process of the rotating disk rotating. In some other embodiments, the plurality of annular conductive parts 221 connected to the first wire harness 310 may be installed on the first connection plate 122, and the plurality of elastic conductive members 123 connected to the second wire harness 320 may be installed on the second connection plate 220. In some other embodiments, the rotating disk may only include the rotating disk body 210 and may not include the second connection plate 220. On the side facing the upper cover 121 of the rotating disk body 210, the above-mentioned annular conductive part 221 or elastic conductive member 123 is installed.
[0029] As shown in FIG. 2, in the embodiment of the present application, the second wire harness 320 is wound around the rotating disk body 210 from the inside to the outside along the first direction with the rotating shaft 111 as the center. Since one end of the second wire harness 320 away from the second connection connector 340 is fixed to the second connection plate 220 of the rotating disk, when pulling out the wound second wire harness 320 from the accommodation space, the second wire harness 320 can drive the rotating disk to rotate along the first direction. In the embodiment of the present application, the data line further includes a decorative member 350. The second wire harness 320 is perforated in the decorative member 350. The decorative member 350 is removably fixed to the case 100 and is located at the wire passing hole of the case 100 corresponding to the second wire harness 320.
[0030] As shown in FIG. 3, in the embodiment of the present application, the coil spring 410 is located within the accommodation space, and both ends of the coil spring 410 are connected to the case 100 and the turntable, respectively. Specifically, the coil spring 410 is telescopically fixed to the bottom case 110 by a coil spring cover plate 420. The first end of the coil spring 410 (i.e., the end located inside the coil spring 410) is fixed to the rotation axis 111 of the bottom case 110 by a method such as fastening. The second end of the coil spring 410 (i.e., the end located inside the coil spring 410) may be fixed to the turntable body 210 by a method such as fastening. When the second wire harness 320 is drawn out from the accommodation space and the turntable is driven so that the second wire harness 320 rotates along the first direction, the turntable body 210 drives the second end of the coil spring 410 to move, so that the coil spring 410 is in a tension state. When the drawn second wire harness 320 is released, the coil spring 410 drives the turntable body 210 to rotate along the second direction opposite to the first direction by its own elastic force, so that the drawn second wire harness 320 can be wound around the turntable again. After the drawn second wire harness 320 is wound around the turntable again, the second wire harness 320 returns to the initial state of being completely wound around the turntable. In some other embodiments, the coil spring 410 may be replaced by an elastic belt or other suitable elastic member that can drive the turntable to rotate along the second direction by its own elastic force.
[0031] The position-limiting assembly is located within the accommodation space and restricts the rotation of the turntable along the second direction when the second wire harness 320 is first pulled out and released, thereby maintaining the second wire harness 320 in the pulled-out state. When the second wire harness 320 is pulled out and released again, the restriction on the rotation of the turntable is released, and the turntable rotates along the second direction by the drive of the coil spring 410, so that the pulled-out second wire harness 320 can be rewound around the turntable again. Here, the first pull refers to the pulling out of the second wire harness 320 when the second wire harness 320 is completely wound around the turntable. When the pulled-out second wire harness 320 is rewound around the turntable again, the second wire harness 320 also returns to the initial state where it is completely wound around the turntable. In this case, the fact that the second wire harness 320 is pulled out again is regarded as the first pull. That is, when the second wire harness 320 is completely wound around the turntable, when the second wire harness 320 is continuously pulled out and released, the first pull and release are the first pull and release. At this time, the second wire harness 320 holds the pulled-out state. The second pull and release are the pull and release again. At this time, the pulled-out second wire harness 320 is rewound around the turntable again. The third pull and release are the first pull and release. At this time, the second wire harness 320 holds the pulled-out state. The fourth pull and release are the pull and release again. At this time, the pulled-out second wire harness 320 is rewound around the turntable again, and so on.Regarding the data line of the embodiment of the present application, when the user needs to use the data line, the user only needs to first pull out the second wire harness 320 that is completely wound around the turntable to the required length and then release it. The second wire harness 320 can be maintained in the pulled-out state. The user can easily use the pulled-out data line to charge or perform data transmission. When the user does not need to use the data line, if the user pulls out and releases it again, the pulled-out second wire harness 320 will automatically wind around the turntable and return to the initial state where it is completely wound around the turntable, and can be accommodated in the case 100. In this way, the accommodation of the second wire harness 320 is easily realized, the space occupied by the second wire harness 320 is reduced, it is not easy to get tangled, and it is easy to carry. The data line of the embodiment of the present application is not only easy for the user to use, but also can extend the service life of the data line and reduce the damage of the data line.
[0032] As shown in FIGS. 2 to 8, in the embodiment of the present application, an annular wall 211 is installed on the turntable body 210 along the circumferential direction, and a plurality of engaging grooves 212 are uniformly installed along the circumferential direction inside the annular wall 211 (i.e., on the side facing the rotation axis 111 of the annular wall 211). The position-limiting assembly is rotatably installed in the case 100 and includes an engaging member 510 that fits into the engaging groove 212. The engaging member 510 is rotatably connected to the bottom case 110 by a screw 520. A through hole 511 is installed in the engaging member, and the screw 520 passes through the through hole 511 and meshes with the screw groove of the bottom case 110, so that the engaging member 510 is position-limited in the bottom case 110 and can rotate around the screw 520 to engage with or disengage from the engaging groove 212. When the wire harness is first pulled out and released, the engaging member 510 is engaged with the engaging groove 212 to limit the rotation of the turntable along the second direction. When the wire harness is pulled out and released again, the engaging member 510 disengages from the engaging groove 212, and the rotation of the turntable along the second direction is no longer limited. Here, when the turntable rotates along the first direction, by driving the engaging member 510 to rotate along the first direction, the engaged engaging member 510 and the engaging groove 212 can be disengaged from each other. Thereby, by controlling the rotation of the engaging member 510, the rotation of the turntable can be controlled to maintain the state where the second wire harness 320 is pulled out or to wind it around the turntable.
[0033] In the embodiment of the present application, the position limiting assembly further includes a self-locking switch configured to be in an unlocked state when pressed and released for the first time and in a self-locked state when pressed and released again. When the self-locking switch is in the unlocked state, the engaging member 510 is pushed to engage with the engaging groove 212, and by restricting the rotation of the rotating disk along the second direction, the pulled-out second wire harness 320 can be maintained in the pulled-out state. When the engaging member 510 is in the self-locked state, the pushing of the engaging member 510 to engage with the engaging groove 212 stops. At this time, the coil spring 410 can rewind the pulled-out second wire harness 320 around the rotating disk by driving the rotating disk to rotate along the second direction by its own elastic force. The engaging member 510 is configured to press the self-locking switch when the wire harness is pulled out for the first time and when it is pulled out again. The engaging member 510 may be configured to rotate along the first direction by the drive of the rotating disk (when the wire harness is pulled out for the first time and when it is pulled out again) when the rotating disk rotates along the first direction, and contact the self-locking switch to press the self-locking switch.
[0034] Specifically, in the embodiments of the present application, the self-locking switch includes a chute 540, a slider 550, a position-limiting rod 560, a spring 570, and a chute cover plate 580. The chute 540 is installed on the bottom case 110, houses the slider 550, is open on the side facing the engaging member 510 of the chute 540, and the slider 550 can extend outside the chute 540 through the opening. The slider 550 can be switched between an extended position extending outside the chute 540 and a housed position housed in the chute 540. When the slider 550 is in the extended position, the engaging member 510 can be pushed and moved so as to engage with the engaging groove 212. On the side of the slider 550 facing the upper cover 121, a one-way runner 551 having a first position A, a second position B, a third position C, and a fourth position D is installed. Between the first position A and the second position B, between the second position B and the third position C, between the third position C and the fourth position D, and between the fourth position D and the first position A, there are a first sliding section, a second sliding section, a third sliding section, and a fourth sliding section respectively. The first sliding section and the fourth sliding section are V-shaped as a whole, and the opening of the V shape faces the opening of the chute 540 (i.e., the engaging member 510). The second sliding section and the third sliding section are also V-shaped as a whole, and the opening of the V shape also faces the opening of the chute 540. The included angle between the second sliding section and the third sliding section is smaller than the included angle between the first sliding section and the fourth sliding section. The position-limiting rod 560 is in a right-angled U shape, and the cross-section along its extending direction is circular. The first end of the position-limiting rod 560 is inserted into the insertion hole at the bottom of the chute 540 and is rotatably connected to the bottom case 110. The insertion hole is located on the side away from the engaging member 510 of the slider 550. The second end of the position-limiting rod 560 is inserted into the one-way runner 551 and is slidable along the one-way runner 551, and is sequentially switched between the first position A, the second position B, the third position C, the fourth position D, and the first position A in the runner 551. The width of the runner 551 is slightly larger than the diameter of the second end of the position-limiting rod 560.At the first position A, the second position B, the third position C, and the fourth position D, steps may be provided to prevent the second end of the position limiting rod 560 from moving in the reverse direction. The spring 570 is located within the chute 540, with one end abutting against the end away from the opening of the chute 540, the other end abutting against the slider 550, and pushing the slider 550 to move to the extended position. The spring 570 may be replaced with an elastic member, such as a metal dome, that can push the slider 550 to move to the extended position. The chute cover plate 250 holds the slider 550, the position limiting rod 560, and the spring 570 between the chute cover plate 580 and the bottom case 110, and may be connected in an adhesive manner to the side away from the bottom case 110 of the chute 540 so that the position limiting rod 560 does not disengage from the runner 551. When the second end of the position limiting rod 560 is at the first position A, the position limiting rod 560 is engaged with the runner 551 (i.e., abuts against the joint of the first sliding section and the fourth sliding section that is V-shaped), thereby holding the slider 550 in the accommodation position. When the second end of the position limiting rod 560 is at the second position B and the fourth position D, the slider 550 is in the accommodation position. When the second end of the position limiting rod 560 is at the third position C, the spring 570 pushes the slider 550 to hold the slider 550 in the extended position, and the opening of the chute 540 contacts the stopper portion provided at the edge of the slider 550, further restricting the slider 550 from moving away from the chute 540.
[0035] As shown in FIG. 4, in the embodiment of the present application, the engaging member 510 includes a first engaging portion 512, a second engaging portion 513, and a contact portion 514 installed along the circumferential direction. The first engaging portion 512, the second engaging portion 513, and the contact portion 514 are all protruding portions of the engaging member 510. The first engaging portion 512 and the second engaging portion 513 are respectively engaged with the engaging groove 212 and the slider 550, and the contact portion 514 contacts the slider 550.
[0036] Referring to FIGS. 6 to 9, the operating principle of the position limiting assembly in the present application will be described.
[0037] As shown in FIG. 6, when the second wire harness 320 is completely wound around the turntable and not pulled out, the second end of the position limiting rod 560 is at the first position A, engaged with the runner 551, and by restricting the slider 550 from moving out of the chute 540, the slider 550 is held at the receiving position.
[0038] As shown in FIG. 7, when the second wire harness 320 is first pulled out, the annular wall 211 rotates along the first direction (i.e., the clockwise direction in FIGS. 6 to 9), the engaging groove 212 of the annular wall 211 contacts the first engaging portion 512, and by pushing the engaging member 510 to rotate along the first direction by the first engaging portion 512, the contact portion 514 presses the slider 550 into the chute 540, moving the slider 550 into the chute 540. In this process, the second end of the position limiting rod 560 moves from the first position A to the second position B. In the embodiment of the present application, a guide slope is provided on the side of the slider 550 facing the engaging member 510, and by contacting the contact portion 514, the guide slope can better push the slider 550 to move into the chute 540.
[0039] As shown in FIG. 8, when the second wire harness 320 is first released, the coil spring 410 drives the turntable to rotate along the second direction (i.e., the counterclockwise direction in FIGS. 6 to 9) by its elastic force, the spring 570 pushes the slider 550 to move out of the chute 540, the second end of the position limiting rod 560 moves from the second position B to the third position C, and the slider 550 is in the extended state. During the movement process of the slider 550, the engaging member 510 is pushed to rotate along the second direction by the contact portion 514, so that the first engaging portion 512 is engaged with the engaging groove 212, and the second engaging portion 513 is engaged with the slider 550. After the first engaging portion 512 is engaged with the engaging groove 212, the rotation of the turntable along the second direction is restricted. After the second engaging portion 513 is engaged with the slider 550, the slider 550 restricts the rotation of the second engaging portion 513 along the second direction. After the first engaging portion 512 is engaged with the engaging groove 212, the coil spring 410 and the turntable are not driven to rotate along the second direction. Further, by continuously engaging the first engaging portion 512 with the engaging groove 212 and continuously restricting the rotation of the turntable along the second direction, the pulled-out second wire harness 320 can be maintained in the pulled-out state. In the embodiment of the present application, the position limiting assembly further includes a torsion spring 530. The torsion spring 530 is fitted on the engaging member 510, one end abuts against the bottom case 110, the other end abuts against the engaging member 510, and due to the elastic force of the torsion spring 530 itself, the engaging member 510 tends to be held at the position when the first engaging portion 512 is engaged with the engaging groove 212. In this way, when the slider 550 is in the extended position, the engaging member 510 can be pushed to engage with the engaging groove 212 more effectively. It should be noted that when the slider 550 is in the retracted position, the torsion spring 530 does not restrict the rotation of the turntable whether it rotates along the first direction or the second direction.
[0040] As shown in FIG. 9, when the second wire harness 320 is pulled out again, the annular wall 211 rotates along the first direction, and by pushing the engaging member 510 to rotate along the first direction by the first engaging portion 512, the contact portion 514 presses the slider 550 into the chute 540, moving the slider 550 into the chute 540. In this process, the second end of the position limiting rod 560 moves from the third position C to the fourth position D.
[0041] As shown in FIG. 6, when the second wire harness 320 is released again, the spring 570 pushes the slider 550 to move out of the chute 540. The second end of the position limiting rod 560 moves from the fourth position D to the first position A, engages with the runner 551, and restricts the slider 550 from moving out of the chute 540, thereby holding the slider 550 at the accommodation position and ceasing to restrict the rotation of the engaging member 510. At this time, the coil spring 410 can drive the rotating disk to rotate along the second direction by its own elastic force. The engaging member 510 rotates along the second direction under the action of the torsion spring 530 and the rotating disk, separates from the slider 550, and the engaging member 510 ceases to restrict the rotation of the rotating disk. The pulled-out second wire harness 320 can be automatically wound around the rotating disk by the action of the coil spring 410 for the next pull-out, be accommodated in the case 100, and return to the initial state of being completely wound around the rotating disk.
[0042] In some other embodiments, the self-locking switch composed of the chute 540, the slider 550, etc. may be replaced with a self-locking switch of another structural form. For example, it corresponds to a key that is first pressed and then pops up (i.e., in the unlocked state) after being released in a ballpoint pen, and is maintained in the pressed state (i.e., in the self-locked state) after being pressed and released again.
[0043] In some other embodiments, the first connection plate 122 and the second connection plate 220 may not be installed on the case 100. Correspondingly, the connection line 300 may include a single wire harness and two connection connectors located at both ends of the wire harness. Both of the two connection connectors are located outside the case 100. When the connection line 300 is wound around the turntable body 210 and fixedly connected to the turntable body 210, when one connection connector is pulled, it drives the rotation of the turntable body 210, and when the other connection connector is pulled, it does not drive the rotation of the turntable body 210.
[0044] In some other embodiments, the first wire harness 310 may not be connected to the first connection connector 330 and may be configured to be directly connected to a power supply device, such as a battery or a charging control chip in a portable power source.
[0045] In addition, the electronic device according to the present application includes a data line as described above. The electronic device may be, for example, a portable power source or other electronic device. The first connection connector 330 of the data line is removably connected to the charging interface of the electronic device, and the second connection connector 340 of the data line is connected to the device to be charged. In some embodiments, the first wire harness 310 of the data line is not connected to the first connection connector 330 and may be directly connected to a battery or a charging control chip in the electronic device, and may be connected, for example, by welding or other means.
