[0076] The data line device described in the embodiments of the present disclosure is described in detail below in combination with Figs. 1 to 9.

[0077] In the embodiment of the present disclosure, the data line device comprises a housing 100, which has a receiving cavity 205, a first opening 101 located at the end side of the housing 100, and a second opening 102 located at the circumferential side of the housing 100. Here, the housing 100 has the receiving cavity 205, the first opening 101 located at the end side of the housing 100, and the second opening 102 located at the circumferential side of the housing 100. A rotating member 200 is rotatably arranged in the receiving cavity 205 and has a wire adjusting cavity 201. A cable 300 comprises a first winding section 310, which is arranged in the wire adjusting cavity 201; a second winding section 320, which is connected with the first winding section 310 and arranged outside the wire adjusting cavity 201; a first end portion 340, which is connected with one end of the first winding section 310 away from the second winding section 320 and located outside the housing 100 through the first opening 101; and a second end portion 350, which is connected with one end of the second winding section 320 away from the first winding section 310 and located outside the housing 100 through the second opening 102. In the extended state, the first winding section 310 is located in the wire adjusting cavity 201 in a first state, and the second winding section 320 is located outside the housing 100. In the storage state, the first winding section 310 is located in the wire adjusting cavity 201 in a second state different from the first state, and the second winding section 320 is arranged around the rotating member 200.

[0078] The data line device of the present disclosure can rotate the rotating member 200 relative to the housing 100 when an external force is applied to stretch the second end portion 350 of the cable 300, and the second winding section 320 is extended out of the housing 100 through the second opening 102, and the first winding section 310 is tightened in the wire adjusting cavity 201, and the first winding section 310 cannot be extended out of the housing 100 through the first opening 101. When the rotating member 200 is rotated in the storage direction, the rotating member 200 can drive the second winding section 320 located outside the housing 100 to move into the housing 100 and be arranged around the rotating member 200, and the first winding section 310 is loosened in the wire adjusting cavity 201, and the first winding section 310 cannot be extended out of the housing 100 through the first opening 101. By arranging the first winding section 310 in the wire adjusting cavity 201, the first winding section 310 can be adjusted in the wire adjusting cavity 201 when the second end portion 350 of the cable 300 is stretched or the second winding section 320 is stored, so that the first end portion 340 and the second end portion 350 of the cable 300 are electrically connected through the first winding section 310 and the second winding section 320. Here, the single-side stretching of the cable 300 can be realized by the integrally arranged cable 300, and other complex structural members are not required, which greatly simplifies the structure of the data line device.

The data line device of the present disclosure, by winding the first winding segment 310 in the wire adjusting cavity 201, when the second end 350 of the cable 300 is stretched or the second winding segment 320 is stored, the first winding segment 310 can be adjusted in the wire adjusting cavity 201, so that the first end 340 and the second end 350 of the cable 300 are electrically connected through the first winding segment 310 and the second winding segment 320. Here, one-side stretching of the cable 300 can be realized through one whole cable 300, without the need to set other complex structure, greatly simplifying the structure of the data line device and improving the electrical conductivity reliability of the cable 300.

[0103] As shown in FIG. 1 and FIG. 2, in some implementations of the embodiments of the present disclosure, the data line device can further include a connecting member 400, at least a part of the connecting member 400 is fixed in the accommodating space 103; the connecting member 400 is arranged through the first connecting hole 206 of the rotating member 200, the rotating member 200 can rotate relative to the connecting member 400, and a first part 410 of the connecting member is located in the adjusting line cavity 201 and has a wire passing cavity 401 which is in communication with the adjusting line cavity 201 and the first opening 101 respectively. The first end portion 340 is located outside the shell 100 through the wire passing cavity 401 of the connecting member 400; since the connecting member 400 is fixed relative to the shell 100, here, the first end portion 340 is located outside the shell 100 through the wire passing cavity 401 of the connecting member 400, and when the second winding section 320 is stretched or accommodated, the first end portion 340 can be fixed relative to the shell 100 or only slightly moved.

[0104] In the present implementation, the first winding section 310 and the second winding section 320 can be directly connected; in the first state, the first winding section 310 is wound outside the first part 410 of the connecting member to define the length of the second winding section 320 extending outside the housing 100; when the second end 350 of the cable 300 is pulled, the cable 300 drives the rotating member 200 to rotate in the stretching direction within the accommodating space 103, the second winding section 320 of the cable 300 gradually extends outside the housing 100, and the first end 340 of the cable 300 can be fixed relative to the housing 100 or can slightly move relative to the housing 100; the first winding section 310 of the cable 300 is gradually tightened in the winding adjusting cavity 201 towards the first part 410 of the connecting member as the rotating member 200 rotates, and the outer diameter of the disc structure formed by the first winding section 310 gradually decreases until the disc structure formed by the first winding section 310 is completely attached to the first part 410 of the connecting member; here, the first winding section 310 cannot be further tightened relative to the first part 410 of the connecting member, and the second winding section 320 completely extends outside the housing 100 to make the data line device in the extended state, so that the disc structure formed by the first winding section 310 is completely attached to the first part 410 of the connecting member to realize that the second winding section 320 completely extends outside the housing 100 to be in the extended state.

[0105] Of course, in other examples, the first winding section 310 and the second winding section 320 can also be connected through the fixed section 330.

[0106] In the present implementation, as shown in FIG. 2, the connecting member 400 can include a first part and a second part arranged in the axial direction; the rotating member 200 can include a winding adjusting cavity 201 and an accommodating cavity 205 arranged in the axial direction; here, the rotating member 200 can be provided with the winding adjusting cavity 201 and the accommodating cavity 205 arranged in the axial direction. The winding adjusting cavity 201 and the accommodating cavity 205 are communicated through a first connecting hole 206; the first part 410 of the connecting member is located in the winding adjusting cavity 201, and the second part 420 of the connecting member is located in the accommodating cavity 205; as shown in FIG. 7 and FIG. 8, the data line device can further include: an elastic member 500 arranged in the accommodating cavity 205 and connected with the second part 420 of the connecting member and the rotating member 200 respectively; the elastic member 500 is used to provide a force to the rotating member 200 to rotate in the accommodating direction, so that in the extended state, the second winding section 320 of the cable 300 can be automatically accommodated outside the rotating member 200.

[0107] Here, the structure of the elastic member 500 is not limited. For example, the elastic member 500 can be a torsion spring.

[0108] Here, as shown in FIG. 8, the first end of the elastic member 500 can be clamped in the fixing groove of the second part 420 of the connecting member to achieve the fixed connection between the first end of the elastic member 500 and the second part 420 of the connecting member. Of course, in the example, the first end of the elastic member 500 can also be fixed to the second part 420 of the connecting member through a threaded structure or a buckle structure. Alternatively, in another implementation, the first end of the elastic member 500 can also be fixedly connected to the shell 100 through a threaded structure or a buckle structure.

[0109] Here, as shown in FIG. 8, the rotating member 200 can have a fixed wall 230 in the accommodating cavity 205, and the second end of the elastic member 500 can be clamped in the fixed wall 230 to achieve the fixed connection between the second end of the elastic member 500 and the rotating member 200. Of course, in the example, the second end of the elastic member 500 can also be fixed to the fixed wall 230 through a threaded structure or a buckle structure.

[0110] In the present implementation, the connecting member 400 can be entirely fixed in the accommodating space 103, or only partially fixed in the accommodating space 103.

[0111] As an example, as shown in FIG. 3, the end of the first part 410 of the connecting member can be exposed on the surface of the shell 100, and here the wire cavity 401 can pass through the end of the first part 410 of the connecting member. Of course, in other examples, the end of the first part 410 of the connecting member can not be exposed on the surface of the shell 100, and here the end of the second part 420 of the connecting member can be located inside the shell 100.

[0112] As an example, as shown in FIG. 4, the end of the second part 420 of the connecting member can also be exposed on the surface of the shell 100; here, the end of the second part 420 of the connecting member can be located in the first opening 101, the wire cavity 401 can pass through the end of the second part 420 of the connecting member, and the first end 340 of the cable 300 directly extends out of the shell 100 from the port of the wire cavity 401 located at the first opening 101. Of course, in other examples, the end of the second part 420 of the connecting member can not be located in the first opening 101, and here the end of the second part 420 of the connecting member can be located inside the shell 100, as long as the wire cavity 401 communicates with the first opening 101.

[0113] In the present implementation, as shown in FIG. 4 and FIG. 9, the data line device can further include a fastener 810, and the connecting member 400 can be fixed to the shell 100 through the fastener 810. Here, the fastener 810 can be a screw. Of course, in other implementations, the connecting member 400 can also be fixed to the shell 100 through a buckle structure or an adhesive structure.

[0114] In some implementations of the embodiments of the present disclosure, the thickness of the first winding section 310 is less than the thickness of the second winding section 320. By setting the thickness of the first winding section 310 to be smaller, the setting space of the line adjusting cavity 201 can be reduced, thereby realizing miniaturization of the data line device. By setting the thickness of the second winding section 320 to be larger, the wear resistance of the second winding section 320 can be improved, preventing the second winding section 320 from being damaged due to long-time stretching.

[0115] Of course, in other implementations, the thickness of the first winding section 310 can also be greater than or equal to the thickness of the second winding section 320.

[0116] As an example, the thickness of the first winding section 310 can be less than or equal to 0.4 mm, and the thickness of the second winding section 320 can be less than or equal to 0.7 mm.

[0117] In the present implementation, the cable 300 can include a wire layer, a first protective layer, and a second protective layer. The wire layer has a first section and a second section. The first protective layer is arranged outside the first section of the wire layer along the length direction of the wire layer. The second protective layer is arranged outside the second section of the wire layer along the length direction of the wire layer. The thickness of the second protective layer is greater than the thickness of the first protective layer. The first section of the wire layer and the first protective layer form the first winding section 310, and the second section of the wire layer and the second protective layer form the second winding section 320. The thickness of the first winding section 310 is set to be smaller by the thinner first protective layer, and the thickness of the first winding section 310 is set to be larger by the thicker second protective layer.

[0118] Here, the wire layer is a signal transmission layer. By arranging the wire layer in an overall structure, the stability of the cable 300 in transmitting electrical signals can be greatly improved.

[0119] Here, the material of the wire layer is not limited as long as it can transmit electrical signals. As an example, the wire layer is a flexible circuit board (English full name: Flexible Printed Circuit, English abbreviation: FPC) wire. Since the thickness of the FPC wire is relatively thin, the wire layer formed by the FPC wire can further reduce the thickness of the cable 300 in each area. At the same time, the setting space of the line adjusting cavity 201 and the setting space of the line winding space 202 can be further reduced, thereby realizing miniaturization of the data line device.

[0120] Here, as shown in FIG. 1 and FIG. 2, when the cable 300 includes the fixed segment 330, the wire layer can further have a third segment between the first segment and the second segment; the cable 300 can further include: a third protective layer, the third protective layer being disposed outside the third segment of the wire layer; at least part of the third protective layer having a thickness greater than the thickness of the second protective layer to form a fixed protrusion 331; the fixed protrusion 331 being clamped in the fixed groove 204 of the rotating member 200; the third segment and the third protective layer forming the fixed segment 330 of the cable 300; so that the wire layer of the overall structure can greatly improve the stability of the cable 300 in transmitting electrical signals, and the third protective layer can not only protect the third segment of the wire layer, but also form the fixed protrusion 331 of the fixed segment 330; here, it is not necessary to additionally provide a fixed structure for the fixed segment 330, which reduces the structure of the data line device and greatly improves the adaptability of the data line device.

[0121] Here, the materials of the first protective layer, the second protective layer and the third protective layer can all be insulating materials. As an example, the materials of the first protective layer, the second protective layer and the third protective layer can all be rubber.

[0122] In some implementations of the embodiments of the present disclosure, the data line device can further include: a limiting member 600, the limiting member 600 being disposed between the shell 100 and the rotating member 200; the limiting member 600 being used to limit the rotating position of the rotating member 200 relative to the shell 100, so that when the second winding segment 320 is pulled out to a specific length, the current extension length can be maintained by the limiting member 600.

[0123] In the present implementation, the setting position and structure of the limiting member 600 are not limited.

[0124] For example, the rotating member 200 can include a winding portion 210 and a plate-shaped portion 220 disposed adjacent along the axial direction; the plate-shaped portion 220 has oppositely disposed first and second sides; the adjusting wire cavity 201 is located at the first side of the plate-shaped portion 220, and the limiting member 600 is disposed between the second side of the plate-shaped portion 220 and the shell 100.

[0125] In the present example, as shown in FIGS. 7 and 8, the second side of the plate-shaped portion 220 can have an inner annular slide 221 and an outer annular slide 222 arranged radially apart; here, the second side of the plate-shaped portion 220 can be provided with the inner annular slide 221 and the outer annular slide 222 arranged radially apart; the plate-shaped portion 220 further has a slide-in passage 223 and a slide-out passage 224 respectively communicating with the inner annular slide 221 and the outer annular slide 222, here, the plate-shaped portion 220 is further provided with the slide-in passage 223 and the slide-out passage 224 respectively communicating with the inner annular slide 221 and the outer annular slide 222, and the plate-shaped portion 220 is further provided with a clamping groove 225 at the slide-in passage 223; here, the plate-shaped portion 220 is further provided with the clamping groove 225 at the slide-in passage 223; the limiting member 600 is rotatably arranged in the housing 100 and has a protruding column 610 arranged axially, as shown in FIG. 9, the protruding column 610 is used for clamping in the clamping groove 225.

[0126] As shown in FIG. 9, the limiting member 600 can further have a seat portion 620, the seat portion 620 can have a second connecting hole 621, here, the seat portion 620 can be provided with the second connecting hole 621, and the housing 100 can have a connecting column 104 inserted in the second connecting hole 621 to achieve that the limiting member 600 is rotatably arranged in the housing 100. Of course, in other examples, the second connecting hole 621 can be arranged in the housing 100, and the connecting column 104 can be arranged in the seat portion 620. Here, the protruding column 610 can be arranged in the part of the seat portion 620 located on the side of the second connecting hole 621.

[0127] In the present example, as shown in FIGS. 7 and 8, the plate-shaped portion 220 can further have a containing cavity 205 located inside the inner annular slide 221; here, the plate-shaped portion 220 can be further provided with the containing cavity 205 located inside the inner annular slide 221; the data line device can further include an elastic member 500 arranged in the containing cavity 205 and connected with the plate-shaped portion 220 and the housing 100 respectively; the elastic member 500 is used for providing a force for rotating the rotating member 200 in the storage direction.

[0128] Of course, in other examples, the force for rotating the rotating member 200 in the storage direction can also be provided by other structures. For example, the data line device can include an operating member, part of the operating member passes through the housing 100 and is connected with the rotating member 200, and part of the operating member is located outside the housing 100, here, an operator can rotate the operating member by an external force to provide the force for rotating in the storage direction.

[0129] In the storage state, the convex column 610 is located in the inner annular slide channel 221, when the second end 350 of the cable 300 is pulled by an external force, the convex column 610 enters the outer annular slide channel 222 from the slide-out channel 224 and slides in the outer annular slide channel 222; when the second winding section 320 is pulled out to a proper length, the external force is removed, here, the rotating member 200 rotates to the storage direction based on the restoring force of the elastic member 500, the convex column 610 reversely slides in the outer annular slide channel 222 and slides into the clamping groove 225 at the slide-in channel 223, so that the rotating member 200 no longer rotates, thereby ensuring the current pulled-out length of the second winding section 320. When it is needed to store the second winding section 320, the second end 350 of the cable 300 can be slightly pulled to make the convex column 610 come out of the clamping groove 225 and re-enter the outer annular slide channel 222, when the external force is removed, the convex column 610 reversely slides in the outer annular slide channel 222 for a small distance, enters the inner annular slide channel 221 from the slide-out channel 224 and continues to reversely slide in the inner annular slide channel 221 until the second winding section 320 is completely stored in the shell 100.

[0130] Of course, in other examples, the second winding section 320 can also be kept at the current pulled-out length in other ways, for example, by clamping the part of the second winding section 320 located at the second opening 102 through an external clamping structure, so that the part of the second winding section 320 located at the second opening 102 is kept at the current pulled-out length by being clamped at the second opening 102 through the external clamping structure.

[0131] In some implementations of the implementation examples of the present disclosure, the data line device can further include a first fixing structure and a second fixing assembly 700. The first fixing structure is connected with the shell 100 and the first end 340 of the cable 300 respectively, so that the first end 340 of the cable 300 is fixed outside the shell 100 and is prevented from moving; the second fixing assembly 700 can include a first fixing member 710 and a second fixing member 720 which are detachably connected; one of the first fixing member 710 and the second fixing member 720 is fixed to the side of the shell 100, and the other of the first fixing member 710 and the second fixing member 720 is fixed to the second end 350 of the cable 300, when the first fixing member 710 and the second fixing member 720 are separated, the second end 350 of the cable 300 can be pulled to make the data line device be in the extended state; when the data line device is in the storage state, the first fixing member 710 and the second fixing member 720 can be detachably connected, so that the second end 350 of the cable 300 is fixed relative to the shell 100, and the overall data line device is ensured to be more tidy.

[0132] In the present implementation, the form of the first fixing structure is not limited. For example, the first fixing structure can be a buckle structure, a threaded structure or an adhesive structure.

[0133] In the present embodiment, the forms of the first fixing member 710 and the second fixing member 720 are not limited. For example, as shown in FIG. 7 and FIG. 9, the first fixing member 710 and the second fixing member 720 can each be a magnetic structure; here, the first fixing member 710 and the second fixing member 720 can be connected by magnetic force adsorption. For another example, one of the first fixing member 710 and the second fixing member 720 is a magnetic structure, and the other of the first fixing member 710 and the second fixing member 720 is a ferromagnetic structure; here, the first fixing member 710 and the second fixing member 720 can also be connected by magnetic force adsorption.

[0134] Of course, in other embodiments, the data line device can also only include one of the first fixing structure and the second fixing member 700.

[0135] The above merely provides an example of the present disclosure, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present disclosure, which should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
