CROSS REFERENCE TO RELATED APPLICATION

This application claims priority to Chinese Patent Application No. 2024219742750, filed on Aug. 15, 2024, which is hereby incorporated by reference in its entirety.

TECHNICAL FIELD

The present application relates to the technical field of data cables, and more particularly to a novel retractable data cable.

BACKGROUND

People often carry electronic products such as mobile phones and tablets when going out. In order to charge the electronic products, people usually carry a power bank equipped with data cable. The common data cable has a long strip structure, which makes it difficult to store and even causes knotting and entanglement when not in use. To solve such problems, a retractable data cable has been designed and published on the market, for example, Chinese patent CN 215732537U discloses a unidirectional free-pulling data cable, by winding the data cable onto the wheel core, a clamping assembly is provided on the outer side of the wheel cover at the top of the wheel core, the clamping assembly is used to cooperate with the elastic member to control the forward and backward rotation of the wheel core, thereby achieving automatic extension and retraction of the data cable.

However, during use of the retractable data cable, frequent bending at the connection between the plug and the data cable may cause the protective layer at the data cable joint to crack, resulting in the exposure of internal optical fibers and wires. Moreover, the tensile force of the retractable data cable at the cracking point of the protective layer will exacerbate the severity of data cable damage, affecting the normal and safe use of the data cable. In addition, the winding and extension range of the retractable data cable is constrained by the elastic member, which is not conductive to stretching the data cable for a long distance in special situations far away from the power socket.

Compared with the existing technologies, the novel retractable data cable of the present disclosure has at least the following beneficial effects.

1. By slidably holding the slider at the top of the drive column to allow the middle of the coil spring and the drive column can rotate on the circuit board, at this time the coil spring no longer provides a reverse elastic force to the rotated winding component to rotate its initial position. Then, manually push the two ends of the shaft to slide the wedge block on the outer side of the shaft along the caliper. The second rollers on the outer side of the shaft stretch the data cable towards the interior of the protective cover, allowing the data cable near one end of the fixed sleeve to be stored and moved to a certain distance to the interior of the protective cover. Thus, the frequently bent and damaged areas on the data cable can be moved to the interior of the protective cover for protection, and the intact position on the data cable can be moved to the fixed sleeve near the plug component, effectively preventing the internal optical fibers and wires from being exposed.

2. By rotating the stud with an external screwdriver to move the splint towards a direction of the data cable, causing the splint to press and fix the data cable to the interior of the fixed sleeve. After adjusting the position of the data cable by the positioning group, the fixed sleeve can be fixed at the rear end of the damaged data cable. When pulling the plug component by hand, the tension of the data cable is applied to the rear of the damaged area of the data cable through the fixed sleeve, effectively preventing the tension of the data cable from acting on the crack of the protective layer and aggravating the severity of the data cable damage.

3. By rotating the screw to slide the risen mouldings into the interior of the swing arm, the clamping component is no longer clamped to the winding component in a fixed rotating state. Then, pulling the plug component can pull out all data cables wrapped around the outside of the winding component, achieving the use of long distance data cables.

4. By rotating the stud in the opposite direction, the risen mouldings are engaged with the notches on the outer side of the driving wheel. The slider at the top of the sliding column is slid and inserted into the rectangular slot at the corresponding position on the second circuit board. The middle of the coil spring is fixed to the second circuit board through the drive column, and the outer side of the coil spring is fixed to the inner side of the second turntable through the pillar. During the process of pulling out the data cable, the coil spring will enwind and store energy. At the same time, the clamping component can fix the winding component after releasing the data cable, allowing the data cable to be stretched out for short distance use. Then, pull the data cable again, the clamping component is no longer fixed the winding component. At this time, under the elastic force of the coil spring, the winding component reels the data cable, making it easier to automatically retract the data cable and achieve a switch use between long distance and short distance of the data cable.

Referring to FIG. 7, in some embodiments of the present disclosure, the positioning group 600 includes a base fixed on the inner bottom of the protective cover 520, two first rollers 611 and two second rollers 612 are rotatably provided on a top surface of the base 610, and the data cable 400 is wound between the first rollers 611 and the second rollers 612 for transmission. A shaft 620 is rotatably inserted into a middle of a corresponding second roller 612, and a wedge block 621 is fixedly sleeved on an outer side of the shaft 620. The interior of the protective cover 520 is provided with a latch 630 that slides and engages with the wedge block 621, and two telescopic rods 640 is fixed between the latch 630 and the protective cover 520.

In some embodiments of the present disclosure, by manually pulling the pull blocks 622 at both ends of the shaft 620, the data cable 400 is pulled towards the interior of the protective cover 520 through the second rollers 612. This allows the damaged area of the data cable 400 that near the fixed sleeve 510 to be moved to the interior of the protective cover 520 for protection. During the movement of the shaft 620, the wedge block 621 on the outer side of the shaft 620 slides along the latch 630, and the teeth on the latch 630 are also wedge-shaped. The latch 630 uses the telescopic rod 640 (existing member, that is a spring telescopic rod) to flexibly contact with the wedge block 621, so the latch 630 can fix the wedge block 621 in its moved position, thereby keeping the shaft 620 be fixed in position after movement, allowing the data cable 400 to be stably stored in the interior of the protective cover 520.

Referring to FIG. 1 and FIG. 2, in some embodiments of the present disclosure, a magnet 121 is fixed on an outer side of the housing base 120, and an iron sheet is fixedly embedded on an outer side of the plug 530. When the data cable is in storage and not in use, the plug component 500 can be magnetically fixed to the magnet 121 for convenient storage of the plug component 500.

Referring to FIG. 3 and FIG. 8, in some embodiments of the present disclosure, a connecting shaft 211 is rotatably connected to a top of the conductive shaft 210, an inner side of the second turntable 320 is fixed with a pillar 322, and two ends of the coil spring 330 are fixedly connected to the connecting shaft 211 and the pillar 33, respectively. In this way, one end of the coil spring 330 is fixed to the connecting shaft 211, and the other end of the coil spring 330 is fixed to the second turntable 320. The connecting shaft 211 is fixed to the second circuit board 130 through the drive column 340. When the second turntable 320 rotates to release the data cable, the second turntable 320 will rotate with the coil spring 330 to collect and store energy. The elastic potential of the coil spring 330 can facilitate the reverse automatic rotation of the second turntable 320 in the later stage to collect the released data cable.

Referring to FIG. 1 and FIG. 8, in some embodiments of the present disclosure, the winding component 300 further includes a drive column 340 fixedly fastened with the connecting shaft 211, and the drive column 340 passes through one end of the second circuit board 130 to slidably connect with a slider 341. The slider 341 is slid to make it inserted into the rectangular slot 131 of the second circuit boar 130, at this time, the connecting shaft 211 cannot rotate on the housing 100, which is beneficial for fixing the middle of the coil spring 330, allowing the coil spring 330 to rotate in the opposite direction after the winding component 300 rotates.

In some embodiments of the present disclosure, a wristband is fixed on the surface of the slider 341 for easy sliding the slider 341. After sliding the slider 341 away from the rectangular slot 131, the drive column 340 can rotate on the second circuit board 130, causing the connecting shaft 211 to no longer be in a fixed state, and the middle of the coil spring 330 to be in an active rotating state. At this time, the winding component 300 rotates to wind up or release the data cable without being affected by the coil spring 330. And the damaged area on the data cable is moved to the interior of the protective cover 520, which will not cause the coil spring 330 to wind up and store energy, and also convenient to release the data cable for long distances. Further, by rotating the drive column 340, longer data cable can also be wound up.

In some embodiments of the present disclosure, the top of the connecting shaft 211 is provided with a notch for easy clamping the coil spring 330, and the bottom of the drive column 340 is fixed with an insert block 342 for clamping with the notch, allowing the drive column 340 to control whether the connecting shaft 211 rotates or not.

Referring to FIG. 9, in some embodiments of the present disclosure, the inner top of the housing base 120 is fixed with a first locating shaft 122 for rotatable installing the swing arm 710, the inner top of the housing base 120 is fixed with a second locating shaft 123 for rotatable installing the rotating wheel 730, and the inner top of the housing base 120 is provided with a mounting groove 124 for receiving a flexure piece 720.

In some other embodiments of the present disclosure, in order to clamp and fix the winding component 300 after releasing the data cable, the following structures are also provided.

Referring to FIG. 3, FIG. 4, and FIG. 6, in some other embodiments of the present disclosure, the clamping component 700 includes a swing arm 710 that is rotatably connected to the inner top of the housing base 120. The outer side of the swing arm 710 is slidably clamped with risen mouldings 710, the outer side of the second turntable 320 is provided with multiple notches 321 that are movable engaged with the rising mouldings 711. The top surface of the swing arm 710 is fixed with the first lug 712 and the second lug 713, the top of the swing arm 710 is fixed with a flexure piece 720, both ends of the flexure piece 720 are in contact with the inner side of the house base 120. The rotating wheel 730 is provided between the first lug 712 and the second lug 713, to rotatably connect with the housing base 120. The outer side of the rotating wheel 730 is provided with the first slots 731 and the second slots 732, with the first slots 731 having a depth greater than the second slots 732.

Specifically, during the process of using the clamping component 700 to retract and release the data cable, when releasing the data cable, the plug component 500 is used to pull the data cable. The data cable rotates with the second turntable 320, causing the risen mouldings 711 on the swing arm 710 to detach from the notches 321 on the second turntable 320. The swing arm 710 deviates from its initial position, and the flexure piece 720 undergoes deformation, providing a reset elastic force to the swing arm 710. After releasing the plug component 500, the elastic force of the coil spring 330 rotates the winding component 300 in the opposite direction to wind up the data cable. However, at this time, the swing arm 710 resets, and the second lug 713 on the swing arm 710 is engaged with the second slots 732 on the rotating wheel 730. Thus the swing arm 710 is limited and fixed, causing the winding component 300 to stop rotating.

When winding up the data cable, one end of the plug component 500 is pulled again, to allow the second turntable 320 rotate again, and the risen mouldings 711 on the swing arm 710 disengages from the notches 321, causing the swing arm 710 to deviate from its initial position. The flexure piece 720 provides the swing arm 710 a restoring force. After the user lets go, the second turntable 320 is reset under the action of the coil spring 330, and at the same time, the flexure piece 720 is reset with the swing arm 710. On the swing arm 710, the first lug 712 is engaged with the first slots 731, and the swing arm 710 is fixed again. Due to the depth of the first slots 731 is greater than that of the second slots 732, when the swing arm 710 is fixed, the angle at which the risen mouldings 711 on the swing arm 710 swings is greater than the angle at which the risen mouldings 711 swings during the data cable being loosen. Additionally, when the risen mouldings 711 stays outside of the notches 321 on the second turntable 320, it cannot prevent the second turntable 320 from rotating, and all data cable are retracted under the action of the coil spring 330.

Referring to FIG. 5, in some other embodiments of the present disclosure, the interior of the swing arm 710 is threadable connected with a screw 714 that being rotatably connecting with the risen mouldings 711. By rotating the screw 714 to make the risen mouldings 711 move away from the second turntable 320, so that the clamping component 700 will no longer control the rotation of the second turntable 320. This makes it convenient for the winding component 300 to release the data cable for long distances, meeting the requirement of pulling out the data cable for long distances in special situations that away from power sockets.

In the present disclosure, the clamping component 700 is the clamping structure disclosed in the Chinese patent CN215732537U titled “unidirectional free-pulling data cable”, and its detailed operating principle shall not be repeated herein.
