[0022] This utility model embodiment provides a data cable mechanism that facilitates storage and protection of the data cable connector end, see reference. Figures 1-10 The device includes a protective shell 1, a cable box 2, a take-up reel 3, a spring 4, a connecting circuit board 5, a first data cable 6, a guide pin 7, a contact circuit board 8, and a second data cable 9. The cable box 2 is installed inside the protective shell 1 and has an accommodating cavity. The take-up reel 3 is rotatably installed inside the accommodating cavity. The spring 4 and the connecting circuit board 5 are both installed on the take-up reel 3. The spring 4 is used to drive the take-up reel 3 to rotate clockwise or counterclockwise. The first data cable 6 is wound on the take-up reel 3. The fixed end of the first data cable 6 is connected to the connecting circuit board 5, and the connector end of the first data cable 6 extends outside the accommodating cavity and is detachably installed on the protective shell 1. The guide pin 7 is set on the cable box 2 and is used to lock the first data cable 6. The contact circuit board 8 is installed on the cable box 2 and is connected to the connecting circuit board 5. The fixed end of the second data cable 9 is connected to the contact circuit board 8, and the connector end of the second data cable 9 is detachably installed on the protective shell 1.

[0023] As an example, a data cable mechanism for convenient storage and protection of the data cable connector includes a protective shell 1, a cable box 2, a take-up reel 3, a spring 4, a connecting circuit board 5, a first data cable 6, a guide pin 7, a contact circuit board 8, and a second data cable 9. During installation, the take-up reel 3, spring 4, connecting circuit board 5, first data cable 6, guide pin 7, and contact circuit board 8 are all housed within the cable box 2, which is installed inside the protective shell 1. This allows the protective shell 1 to protect the cable box 2 and its internal components, extending the device's lifespan. Specifically, the cable box 2 has a cavity within it, and the take-up reel 3 is rotatably mounted within this cavity. The spring 4 is then installed on the first reel of the take-up reel 3. On the surface, the retraction property of the spring 4 can drive the take-up reel 3 to rotate clockwise or counterclockwise, so that the take-up reel 3 returns to its original rotation. The connecting circuit board 5 is installed on the second reel surface of the take-up reel 3. The first data cable 6 is wound on the take-up reel 3. The fixed end of the first data cable 6 is connected to the connecting circuit board 5. The connector end of the first data cable 6 extends outside the accommodating cavity and can be detachably installed on the protective shell 1. The contact circuit board 8 is installed on the cable box 2 and is connected to the connecting circuit board 5 through the contact spring 19. In this way, the second data cable 9 and the first data cable 6 are connected through the connecting circuit board 5, the contact spring 19 and the contact circuit board 8, so that the user can use the data cable mechanism.

[0024] The fixed end of the second data cable 9 is mounted on the protective shell 1. The fixed end of the second data cable 9 passes through the protective shell 1 and connects to the contact circuit board 8. The connector end of the second data cable 9 is detachably mounted on the protective shell 1. This allows the connector end of the second data cable 9 to be fixed to the protective shell 1 when not in use, facilitating storage and protection of the connector end and preventing damage from impact or pressure. The first data cable 6 is a retractable data cable. In use, the connector end of the first data cable 6 is detached from the protective shell 1, and the first data cable 6 is pulled out for use. When not in use, pulling out the first data cable 6 causes the spring 4 to tighten, generating a reaction force. Driven by this reaction force, the first data cable 6 is retracted, and finally, the connector end of the first data cable 6 is fixed to the protective shell 1 for storage and protection, preventing damage from impact or pressure. The guide pin 7 is set on the wire box 2. The first data line 6 can be locked by the guide pin 7 so that the length of the first data line 6 pulled out can be adjusted according to the user's needs.

[0025] In one embodiment, reference is made to Figure 2 , Figure 3 and Figure 4 The protective shell 1 is provided with a connector fixing position 10, and the connector end of the first data cable 6 is detachably installed in the connector fixing position 10; the protective shell 1 is also provided with a placement groove 11 and a cable passage 12 communicating with the inside of the protective shell 1; the fixing end of the second data cable 9 is installed in the cable passage 12, and the connector end of the second data cable 9 is detachably installed in the placement groove 11.

[0026] As an example, the protective housing 1 is provided with a connector fixing position 10, and the connector end of the first data cable 6 is detachably installed in the connector fixing position 10. When using the data cable mechanism, the connector end of the first data cable 6 is removed from the connector fixing position 10 so that the user can pull out the first data cable 6. When the data cable mechanism is not used, the connector end of the first data cable 6 is fixed in the connector fixing position 10 to prevent the connector end of the first data cable 6 from being damaged by collision or squeezing. The protective housing 1 is also provided with a placement groove 11 and a cable passage 12 communicating with the inside of the protective housing 1. During installation, the fixed end of the second data cable 9 is installed in the cable passage 12, and the fixed end of the second data cable 9 passes through the protective housing 1 and connects with the contact circuit board 8. The connector end of the second data cable 9 is detachably installed on the protective housing 1. With this configuration, when using the data cable mechanism, the connector end of the second data cable 9 can be removed from the protective housing 1; when the second data cable 9 is not in use, the connector end can be fixed on the protective housing 1 to prevent the connector end of the second data cable 9 from being damaged by collision or squeezing. The placement groove 11 is a long strip-shaped groove that can be adapted to the connector end of the protective shell 1 and the second data cable 9. It can completely embed the connector end of the first data cable 6 into the placement groove 11 without protruding from the surface of the protective shell 1.

[0028] As an example, a fastening element 13 is provided on the wall of the placement groove 11. When the connector end of the second data cable 9 is placed in the placement groove 11, the fastening element 13 can engage the connector end of the second data cable 9 to ensure that the connector end of the second data cable 9 is securely fixed in the placement groove 11 and prevent it from falling out of the placement groove 11. The fastening element 13 can be configured as an elastic buckle or an elastic post, using elastic deformation to fix the connector end of the second data cable 9; it can also be replaced with a magnetic element, using magnetic principles to fix the connector end of the second data cable 9. There are two fastening elements 13, each set on one of the two walls of the placement groove 11. The two fastening elements 13 can be set correspondingly or not, which can further improve the reliability of fixing the connector end of the second data cable 9.

[0029] The protective casing 1 also includes a constraint member 14, which cooperates with the placement groove 11 to form a constraint space. When the connector end of the second data cable 9 is placed in the placement groove 11, the constraint space constrains the wire segment of the second data cable 9, thereby further improving the secure fixation of the connector end of the second data cable 9. Multiple constraint members 14 are provided, for example, two, arranged in a staggered manner. This allows for constraint of the wire segment of the second data cable 9 from multiple points, increasing the constraint area and ensuring the secure fixation of the connector end of the second data cable 9. Additionally, the wire segment of the second data cable 9 can be bent to form a handle for the user to carry the data cable mechanism.

[0030] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 4 The data cable mechanism for easy storage and protection of the data cable connector also includes a locking member 15, which is disposed on the protective shell 1 and is used to fix the connector end of the first data cable 6.

A first mounting groove 103 is provided on the inner wall of the first housing 101, and a second mounting groove 104 is provided on the inner wall of the second housing 102. During installation, the first housing 101 and the second housing 102 are connected by a connecting structure, so that the first mounting groove 103 and the second mounting groove 104 align to form a mounting cavity for installing the junction box 2, thereby protecting the junction box 2 and the components inside it, and improving the service life of the equipment. The locking member 15 includes a first magnet and a second magnet. The first magnet is installed on the first housing 101, and the second magnet is installed on the second housing 102.

[0035] As an example, the connection structure includes any one of the plug-in assembly 16, the snap-fit ​​assembly, and the screw-fit assembly; For example, refer to Figure 2The plug-in assembly 16 includes plug-in posts 161 and sockets 162. Multiple plug-in posts 161 are provided on the first housing 101, and multiple sockets 162 are provided on the second housing 102. Each plug-in post 161 is plugged into a socket 162. By plugging multiple plug-in posts 161 into multiple sockets 162 respectively, the first housing 101 and the second housing 102 can be connected to form a whole. The plug-in principle facilitates the assembly or separation of the first housing 101 and the second housing 102.

[0036] For example, the snap-fit ​​assembly includes a first snap-fit ​​member and a second snap-fit ​​member. A plurality of first snap-fit ​​members are provided on the first housing 101 and a plurality of second snap-fit ​​members are provided on the second housing 102.

When the slide rod 71 slides from the major axis to the minor axis, the slide rod 71 slides along the outer wall of the take-up track 341 or the pay-off track 342. The take-up track 341 is located inside the unwinding track 342. To allow the slide bar 71 to slide and switch back and forth between the take-up track 341 and the unwinding track 342, a first switching port 343 and a second switching port 344, as well as a first positioning port 345 and a second positioning port 346, are respectively provided at the transition between the major and minor axes of the take-up track 341 and the unwinding track 342. The first switching port 343 and the second switching port 344 are channels for the slide bar 71 to switch between the two tracks. The first positioning port 345 and the second positioning port 346 are used to lock and brake the slide bar 71 and the entire take-up reel 3. When the slide bar 71 slides into either the first positioning port 345 or the second positioning port 346, the take-up reel 3 is locked and stops rotating. The first positioning port 345 and the second positioning port 346 are double-set so that the slide bar 71 can be locked once every half turn. In order to enable the slide bar 71 to switch smoothly from the take-up track 341 and the release track 342, the release track 342 is provided with a first protrusion 347 and a second protrusion 348, which are respectively located inside the first switching port 343 and the second switching port 344.

[0040] In this example, an external force is applied to the connector end of the first data cable 6. When pulled outward, the first data cable 6 drives the take-up reel 3 to rotate counterclockwise around the pivot 17 at the center of the bottom shell 21 (based on the user's viewing angle). During the rotation of the take-up reel 3, the mainspring 4 inside the mainspring chamber 32 moves synchronously: the inner end of the mainspring 4 is connected to the pivot 17 (stationary end), and the outer end is connected to the inner wall of the mainspring chamber 32 (moving end). The rotation of the take-up reel 3 causes the mainspring 4 to be gradually tightened, generating elastic deformation and storing elastic potential energy, providing power for subsequent winding. During this stage, the take-up reel 3 and the pivot 17 adopt a low-friction fit to avoid jamming due to excessive frictional resistance. At the same time, the take-up groove 31 (radial side of the take-up reel 3) rotates with the take-up reel 3, gradually releasing the wound first data cable 6, ensuring a smooth pull-out process. When the winding condition is triggered (such as unlocking the positioning), the spring 4 releases the stored elastic potential energy, pushing the take-up reel 3 to rotate clockwise in the opposite direction. When the take-up reel 3 rotates clockwise, the first data line 6 is rewound into the take-up groove 31 until the first data line 6 is completely retracted or the spring 4 returns to its initial slack state, thus achieving automatic winding without the need for additional external force intervention.

[0041] The take-up reel 3 has two elliptical tracks on its axial top surface: the inner track is the take-up track 341, and the outer track is the unwind track 342. Both tracks have a long axis (corresponding to the maximum extended length of the first data cable 6) and a short axis (corresponding to the retracted state of the first data cable 6). Key functional ports are located at the transition between the long and short axes: switching ports (first switching port 343 and second switching port 344) provide a channel for the guide pin 7's slide rod 71 to switch between tracks, ensuring that the slide rod 71 can flexibly switch between the take-up track 341 and the unwind track 342. Positioning ports (first positioning port 345 and second positioning port 346) mechanically lock the position of the slide rod 71, thereby preventing the take-up reel 3 from rotating and fixing the length of the first data cable 6; convex peaks (first convex peak 347 and second convex peak 348) are located inside the unwind track 342, next to the switching port, assisting the slide rod 71 in smoothly switching tracks and avoiding jamming or accidental triggering.

[0042] When the first data cable 6 is pulled, the take-up reel 3 rotates counterclockwise, and the slide rod 71 of the guide pin 7 is limited by the track and slides along the wire release track 342 from the short axis end to the long axis end (clockwise). During this stage, the slide rod 71 always fits against the inner wall of the wire release track 342 to ensure that the first data cable 6 is pulled out stably. When the first data cable 6 is pulled out to the target length and the user releases it, the take-up reel 3 begins to rotate clockwise under the reaction force of the spring 4. The slider 71 changes direction with the rotation of the take-up reel 3 and slides along the unwinding track 342 from the long axis end to the short axis end (counterclockwise). Since the first positioning port 345 and the second positioning port 346 are distributed at intervals, the slider 71 will encounter a positioning port every half turn. Under the action of inertia and track limit, the slider 71 will engage with the nearest positioning port (first positioning port 345 or second positioning port 346), and prevent the take-up reel 3 from continuing to rotate through mechanical engagement, so that the first data cable 6 maintains the current pulled-out length. In addition, when the slider 71 slides to the first positioning port 345 or the second positioning port 346, it will make a sound to prompt the user and enhance the user's interest and precise control. Compared to the traditional single-positioning design, the dual-positioning port allows the take-up reel 3 to lock once every half turn, significantly shortening the rotation distance from release to locking, reducing the amount of retraction of the first data cable 6 caused by additional rotation, and achieving a precise match between the pulled-out length and the used length. The number of positioning ports can be set to multiple, preferably two.

[0043] The user gently pulls the first data cable 6 outwards again, causing the take-up reel 3 to rotate briefly counterclockwise. The slider 71, following the change in force on the track, disengages from the positioning port and continues to slide along the pay-off track 342 towards the longer axis (clockwise). When the slider 71 reaches the switching port (first switching port 343 or second switching port 344), it smoothly switches from the pay-off track 342 to the inner take-up track 341 under the guidance of the track convex peaks. After the slider 71 enters the take-up track 341, the take-up reel 3 continues to rotate clockwise under the driving force of the spring 4. The slider 71 slides along the take-up track 341 from the longer axis to the shorter axis (counterclockwise). During this stage, the slider 71 adheres to the outer wall of the take-up track 341 without any locking intervention from the positioning port. The take-up reel 3 stops rotating when the slider 71 reaches the shorter axis of the take-up track 341, and the first data cable 6 is completely wound into the take-up groove 31, completing the winding process.

[0044] In one embodiment, reference is made to Figure 1 , Figure 5 and Figure 6The bottom shell 21 is a basin-shaped shell, which includes a rotating shaft 17 located in the center, a snap-fit ​​part 211 located around the basin edge, and a data cable inlet / outlet 212 located at the right front of the basin edge; the rear end of the top shell 22 is provided with a device interface 221, the bottom surface of the top shell 22 is provided with a contact plate mounting position 222 in the middle, and a guide pin position 223 is provided on the right side of the contact plate mounting position 222; the contact circuit board 8 is installed in the contact plate mounting position 222, the fixed end of the second data cable 9 is connected to the part of the contact circuit board 8 exposed from the device interface 221, and a guide pin 7 is installed in the guide pin position 223; the top shell 22 includes a snap-fit ​​part 224 located around its four perimeter, a screw hole 225 located at the center of its top, and a guide pin position 223 located at its bottom edge, a guide pin fixing shaft 20 located in the guide pin position 223, and a guide pin 7 installed on the guide pin fixing shaft 20. The contact spring 19 includes a first contact spring 191 and a second contact spring 192; the connecting circuit board 5 is provided with a first contact spring position 51 and a second contact spring position 52; the first contact spring 191 and the second contact spring 192 are respectively mounted on the first contact spring position 51 and the second contact spring position 52. The connector end of the first data line 6 extends from the data line inlet / outlet 212, and the fixed end of the first data line 6 is electrically connected to the second contact spring 192; the first contact spring 191 is electrically connected to the contact circuit board 8 through the connecting circuit board 5. The bottom surface of the contact circuit board 8 is provided with a circular printed circuit connected to the device interface 221, and the first contact spring 191 and the second contact spring 192 are rotatably in contact with the circular printed circuit, thereby realizing the electrical connection between the fixed end of the first data line 6 and the device interface 221.

[0045] When in use, pull the first data cable 6 outward, the take-up reel 3 rotates counterclockwise, and the slide bar 71 always rotates clockwise along the take-up track 341. When the pull stops, under the action of the spring 4, the take-up reel 3 starts to rotate clockwise, and the slide bar 71 rotates counterclockwise. Since there are two of each of the first switching port 343 and the second switching port 344, as well as two of the first positioning port 345 and the second positioning port 346, the slide bar 71 will encounter a switching port and a positioning port every half turn. The slide bar 71 slides into the last positioning port it encounters and is locked. The actual data cable pulled out is half a turn less than the actual data cable used.

[0046] After use, pull the first data cable 6 outwards again. The slider 71 moves clockwise out of the first positioning port 345 or the second positioning port 346 and into the take-up track 341. Then it slides counterclockwise within the take-up track 341. The take-up reel 3 rotates clockwise under the action of the spring 4. When the slider 71 passes the first protrusion 347 or the second protrusion 348, it reaches the second positioning port 346 or the first positioning port 345. At this time, the slider 71 slides from the short axis to the long axis. The slider 71 will slide counterclockwise along the inside of the take-up track 341. Therefore, the slider 71 can smoothly pass through the second positioning port 346 or the first positioning port 345 and continue to slide. The take-up reel 3 rotates clockwise, and the first data cable 6 is retracted.

[0047] In one embodiment, the bottom shell 21 is integrated with the first shell 101 as a single unit; the top shell 22 is integrated with the second shell 102 as a single unit.

[0048] As an example, the bottom shell 21 is integrated with the first shell 101 into a single structure; the top shell 22 is integrated with the second shell 102 into a single structure. This arrangement reduces the connection gaps and potential loosening points of the product, and improves the overall impact and vibration resistance. The single-piece design may reduce redundant materials, and the overall structure saves two shell structures, simplifies the assembly process, and improves production efficiency. While ensuring the structural strength and stability of the product, the overall thickness of the product is reduced, thus lowering costs. The single-piece structure can achieve smoother lines and seamless surfaces, improving the product's aesthetics.

[0049] In one embodiment, reference is made to Figure 8 and Figure 9 The axial bottom surface of the take-up reel 3 is also provided with a limiting member 35; the limiting member 35 is located in the take-up groove 31 and forms a limiting gap with the outer wall of the spring chamber 32; the limiting gap is used to limit the fixed end of the first data line 6.

[0050] As an example, a limiting member 35 is also provided on the axial bottom surface of the take-up reel 3 (i.e., the first reel surface of the take-up reel 3); the limiting member 35 is located inside the take-up groove 31, forming a limiting gap with the outer wall of the spring chamber 32; this arrangement allows the fixed end of the first data cable 6 to be limited through the limiting gap to prevent product failure. After the fixed end of the first data cable 6 is assembled, it needs to be fixed with adhesive to prevent it from sliding during use and thus avoiding product failure.

[0051] In one embodiment, both the connecting circuit board 5 and the contact circuit board 8 are provided with a plating protective surface.

[0052] As an example, both the connecting circuit board 5 and the contact circuit board 8 are provided with a plating protective surface to prevent damage to the product caused by electric arcs or sparks due to current or voltage during use. In addition, lubricating oil is applied to the plating protective surface during production to reduce the wear rate of the circuit board caused by friction and increase the product's service life.

[0053] In one embodiment, both the fixed end of the first data line 6 and the fixed end of the second data line 9 are provided with bare wire structures; the bare wire structure includes a main wire and a fireproof material covered on the main wire; or, the bare wire structure includes a main wire, a fireproof material covered on the main wire, and an anti-interference layer covered on the fireproof material.

[0054] As an example, both the fixed ends of the first data cable 6 and the second data cable 9 are equipped with bare wire structures. To meet usage requirements and improve safety, the bare wire structures have two structural forms. The first type includes a main wire and a fire-retardant material (such as TPU fire-retardant material) covering the main wire, giving the bare wire structure fire resistance while also providing the flexibility and elasticity required for a stretchable cable. The second type includes a main wire, a fire-retardant material covering the main wire, and an anti-interference layer covering the fire-retardant material. This gives the bare wire structure all the characteristics of the first type while also providing anti-interference performance. Additionally, both the first data cable 6 and the second data cable 9 can be wrapped with a braided layer, which improves the durability and feel of the data cables. The braided layer can undergo a special process to prevent pilling after use.
