[0043] Example

[0044] Referring to Figures 1-8, this embodiment proposes a retractable data cable device with an automatic connector retraction mechanism. For ease of description, the retractable data cable device with an automatic connector retraction mechanism will be referred to simply as a data cable in the following text.

[0045] The data cable includes a cable body 100, a housing 400, a coil spring 440, a winder 430, and a positioning component 450, wherein the coil spring 440, the winder 430, and the positioning component 450 are all disposed within the housing 400. The cable body 100 is wound around the winder 430; the coil spring 440 provides a driving force to the winder 430, causing the winder 430 to wind the cable body 100; the winder 430 is rotatably connected to the housing 400; the positioning component 450 is used to lock or unlock the winder 430 or the cable body 100. The coil spring 440 and the winder 430 enable automatic winding of the cable body 100, allowing it to be stored inside the housing 400.

[0046] In this application, the data cable also includes a storage section 310 and a guide structure 500. A transmission connector 200 is provided at the end of the cable body 100. The storage section 310 is used to store the transmission connector 200, and the guide structure 500 is used to guide the transmission connector 200 so that the transmission connector 200 is automatically stored in the storage section 310 when the cable body 100 is stored inside the housing 400.

[0047] The transmission connector 200 includes a transmission interface 201, which includes a USB 2.0 interface, a USB 3.0 interface, and a Type-C interface, etc. The cross-section of the cable 100 can be a flat structure, which can avoid twisting and knotting of the cable 100, thereby facilitating the winding of the cable 100.

[0048] Referring to Figure 2, the housing 400 includes a first housing portion 410 and a second housing portion 420 that are detachably connected. A winding device 430 is rotatably connected to the second housing portion 420; a coil spring 440 is mounted on the winding device 430, with its center end fixed to the second housing portion 420 and its outer end fixedly connected to the middle section of the wire body 100. The first housing portion 410 and the second housing portion 420 can be fixedly connected by snap-fit, screw connection, or other methods. After the first housing portion 410 and the second housing portion 420 are assembled, they form an inner cavity of the housing 400, where both the winding device 430 and the coil spring 440 are disposed. The first housing portion 410 and the second housing portion 420 can be connected to the wire guide cover 300 by one or a combination of screw connection, snap-fit, or other connection methods.

[0049] The above provides a brief description of the structure of the housing 400. Specific structures such as the positioning component 450 can be referenced from existing technologies and will not be elaborated upon further. For example, the positioning component 450 may include a ratchet, etc.

[0050] The driving force is provided by the coil spring 440, which automatically drives the winder 430 to rotate after the winder 430 is unlocked, thereby achieving the winding of the yarn 100. During the winding process of the yarn 100, when the transmission connector 200 moves to the guide structure 500, the transmission connector 200 is automatically fixed in the storage part 310 under the action of the guide structure 500, thereby achieving the storage of the transmission connector 200.

[0051] As shown in Figure 1, the housing 400 includes a first end face 401 and a second end face 402, which are respectively located on both sides of the housing 400 in the thickness direction. A side portion 403 is provided between the first end face 401 and the second end face 402, wherein the storage portion 310 is located in the side portion 403.

[0052] Referring to Figures 3 and 4, when the transmission connector 200 is pulled to the guide structure 500 by the wound-up yarn 100, the guide structure 500 guides the transmission connector 200 so that the transmission connector 200 can be automatically stored in the storage section 310. In Figure 3, the transmission connector 200 is in the stored state, and the yarn 100 is in the fully wound state.

[0053] When the transmission connector 200 moves to the guide structure 500 under the traction of the winding yarn 100, the guide structure 500 applies a force to the tail of the transmission connector 200, thereby guiding the transmission connector 200 towards the storage part 310, thus reducing the distance between the transmission connector 200 and the storage part 310. As the distance between the transmission connector 200 and the storage part 310 decreases, the first connector 210 and the second connector 330 interact with each other, fixing the transmission connector 200 inside the storage part 310. This achieves the storage and fixation of the transmission connector 200, thus improving the convenience of storing the transmission connector 200 and also protecting the transmission connector 200.

[0054] Referring to Figure 3, in this embodiment, both ends of the cable 100 are provided with transmission connectors 200. The storage portion 310 corresponds one-to-one with each transmission connector 200.

[0055] Referring to Figures 1 and 2, the housing 400 is positioned corresponding to the storage portion 310, which is located on the cable guide cover 300. Specifically, the cable guide cover 300 is located on the side 403 of the housing 400.

[0056] The storage section 310 has a threading hole 320 for the cable 100 to pass through. The threading hole 320 is connected to the interior of the housing 400.

[0057] As shown in Figure 7, in this embodiment, the storage portion 310 has a groove-shaped structure. The storage portion 310 includes a first groove end 311 and a second groove end 312, which are respectively located at both ends of the length direction of the storage portion 310. A wire hole 320 is provided on the bottom surface of the first groove end 311. In Figure 7, the length direction of the storage portion 310 is parallel to the direction indicated by arrow x.

[0058] As shown in Figures 7-10, in this embodiment, the guide structure 500 includes a guide wall 510, which faces the receiving portion 310 and covers one end of the receiving portion 310 corresponding to the position where the line 100 passes through. Specifically, the guide wall 510 covers the first groove end 311.

[0059] A passageway 520 is formed between the guide wall 510 and the bottom surface of the receiving part 310. The passageway 520 is used for the cable 100 and the transmission connector 200 to pass through, and the passageway 520 is connected to the cable hole 320. The transmission connector 200 can only be partially inserted into the passageway.

[0060] In this embodiment, the guide wall 510 is an arc-shaped surface, and the guide wall 510 includes a first wall end 511 and a second wall end 512 located at its two ends. The first wall end 511 is located outside the storage part 310, and the second wall end 512 is located inside the storage part 310.

[0061] The first wall end 511 faces the side of the storage portion 310 away from the position where the line 100 passes through. Along the length of the storage portion 310, there is a gap between the first wall end 511 and the corresponding storage portion 312. It can be understood that the guide structure 500 is not covered by the second groove end 312. Specifically, the first wall end 511 faces the side where the second groove end 312 is located; there is a gap between the first wall end 511 and the second groove end 312.

[0062] The first wall end 511 guides the cable 100 and the transmission connector 200, allowing the cable 100 and the transmission connector 200 to pass smoothly through the passageway 520.

[0063] Compared to the cable 100, the transmission connector 200 has a larger cross-sectional area and less elasticity. Because of the gap between the first wall end 511 and the second groove end 312, the transmission connector 200 is more easily stored in the storage section 310; furthermore, due to the gap, the transmission connector 200 in its stored state is at least partially exposed outside the passageway 520, thereby facilitating the user's gripping and pulling of the transmission connector 200.

[0064] The second wall end 512 extends toward the thread hole 320. The second wall end 512 guides the wire 100, allowing the wire 100 to pass smoothly through the thread hole 320.

[0065] As shown in Figure 10, the guide structure 500 includes an insertion part 530, which is inserted into the receiving part 310. The insertion part 530 and the receiving part 310 are detachably connected, wherein a second wall end 512 is provided on the insertion part 530.

[0066] As shown in Figures 7 and 10, the insertion part 530 is provided with a first mounting structure 531, and the storage part 310 is provided with a second mounting structure 313. The first mounting structure 531 and the second mounting structure 313 are detachably connected. Through the cooperation of the first mounting structure 531 and the second mounting structure 313, the connection between the guide structure 500 and the storage part 310 is realized.

[0067] In the first mounting structure 531 and the second mounting structure 313, one is a snap-fit ​​and the other is a slot, wherein the snap-fit ​​and the slot are engaged; or / and,

[0068] In the first mounting structure 531 and the second mounting structure 313, one is a plug-in post and the other is a plug-in hole, wherein the plug-in post is inserted into the plug-in hole.

[0069] The cooperation between the first mounting structure 531 and the second mounting structure 313 can not only connect the guide structure 500 and the storage part 310, but also position the assembly between the guide structure 500 and the storage part 310.

[0070] As shown in Figures 7 and 10, in this embodiment, the first mounting structure 531 includes a snap fastener 5311 and a plug-in post 5312, and the second mounting structure 313 includes a slot 3131 and a plug-in hole 3132. The snap fastener 5311 corresponds one-to-one with the slot 3131, and the plug-in post 5312 corresponds one-to-one with the plug-in hole 3132. The cross-sectional shape of the plug-in post 5312 can be rectangular, circular, etc. Referring to Figure 10, the guide structure 500 is provided with two snap fasteners 5311, which are placed on both sides of the guide structure 500; there are two plug-in posts 5312 with rectangular cross-sections, which are placed on both sides of the guide structure 500; and there is one plug-in post 5312 with circular cross-sections, which is located near the second wall end 512.

[0071] In other embodiments, the type, quantity, and installation position of the first mounting structure 531 and the second mounting structure 313 can be configured as needed. For example, the first mounting structure 531 may include only two snaps, and the second mounting structure 313 may include only two slots; or, for another example, the first mounting structure 531 may include only one insertion hole, and the second mounting structure 313 may include only one insertion post.

[0072] In this embodiment, the data cable also includes a first connector 210 and a second connector 330. During the winding process of the cable body 100, when the transmission connector 200 moves to the guide structure 500, the transmission connector 200 is automatically housed in the housing portion 310 under the action of the guide structure 500. At the same time, under the interaction of the first connector 210 and the second connector 330, the transmission connector 200 is automatically fixed in the housing portion 310, thereby achieving the fixation of the transmission connector 200.

[0073] Specifically, the first connector 210 is disposed on the transmission connector 200, and the second connector 330 is disposed on the storage part 310. The first connector 210 and the second connector 330 are detachably connected so that the transmission connector 200 is detachably fixed to the storage part 310.

[0074] The first connector 210 and the second connector 330 are magnetically connected. Thus, when the transmission connector 200 approaches the storage part 310, the first connector 210 and the second connector 330 will attract each other under the action of the magnetic field, thereby enabling the transmission connector 200 to be automatically fixed in the storage part 310.

[0075] In the first connector 210 and the second connector 330, one is a magnet and the other is a magnetic conductor; or, both the first connector 210 and the second connector 330 are magnets.

[0076] Magnetic components can be magnetized. Specifically, they can be made of magnetically conductive materials such as iron.

[0077] In this embodiment, both the first connector 210 and the second connector 330 are magnets.

[0078] In other embodiments, the first connector 210 and the second connector 330 may be configured as needed. For example, the first connector 210 may be a magnet and the second connector 330 may be a magnetic conductor; or, for another example, the first connector 210 may be a magnetic conductor and the second connector 330 may be a magnet.

[0079] Both the first connector 210 and the second connector 330 can adopt a block structure, which facilitates processing and installation.

[0080] As shown in Figures 5 and 6, the transmission connector 200 has a mounting groove 220, and the first connector 210 is embedded inside the mounting groove 220. A protective shell 230 is fitted onto the transmission connector 200, and the first connector 210 is located inside the protective shell 230. The protective shell 230 is fitted onto the transmission connector 200 after the first connector 210 is installed.
