[0068] The technical solution of the present application is further elaborated in detail below with reference to the accompanying drawings and specific embodiments.

[0069] In the description of the embodiments of this application, it should be noted that, unless otherwise specified and limited, the term "connection" should be understood in a broad sense. For example, it can be an electrical connection, or it can be the internal connection between two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meaning of the above terms can be understood according to the specific circumstances.

[0070] It should be noted that the terms "first, second, and third" in the embodiments of the present application are merely used to distinguish similar objects and do not represent a specific ordering of the objects. It is understood that the terms "first, second, and third" can be interchanged to represent a specific order or precedence where permitted. It should be understood that the objects distinguished by "first, second, and third" can be interchanged where appropriate, such that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0071] The following combination Figures 1 to 8 The data line device described in the embodiments of the present application is described in detail.

[0072] In an embodiment of the present application, a data cable device includes a housing 100, a winding member 200, a cable 300, a damper 400, a rotating member 500, and a moving member 600. The housing 100 has a receiving cavity 103 and at least one opening communicating with the receiving cavity 103; the winding member 200 is rotatably disposed within the receiving cavity 103; and the cable 300 includes a winding section 310 and at least one end. The winding section 310 is used to be wound around the winding member 200; at least one end is connected to the winding section 310 and is located outside the shell 100 through at least one opening; the damper 400 includes a seat 410 and a working part 420 rotatably connected to the seat 410; the seat 410 is fixed in the accommodating chamber 103; the rotating member 500 is rotatably arranged in the accommodating chamber 103 and is connected to the working part 420; the moving member 600 is axially movably arranged in the accommodating chamber 103, and has a mating position rotatably connected to the rotating member 500 and the winding member 200, and a separation position separated from at least one of the rotating member 500 and the winding member 200; when the cable 300 is stored, the moving member 600 is in the mating position, so that the working part 420 rotates to provide damping force; when the cable 300 is stretched, the moving member 600 is in the separation position.

[0073] In related art, a data cable structure includes a shell structure, a rotating structure, and a cable structure; the rotating structure achieves stretching and storage of the cable structure. However, the cable structure is stored at a high speed, which can easily injure the user. In the data cable device of the present application, when the cable 300 is stored, the movable member 600 is in a mating position, causing the working portion 420 to rotate and provide a damping force. The damping force provided by the working portion 420 of the damper 400 can significantly reduce the speed at which the winding member 200 rotates in the storage direction, thereby preventing the cable 300 from being stored at a high speed and injuring the user.

[0074] In the embodiment of the present application, the structure of the housing 100 is not limited. Figure 1 As shown, the housing 100 may include a first half shell 110 and a second half shell 120. The second half shell 120 may be connected to the first half shell 110 via a snap-fit structure, a threaded structure, an adhesive structure, etc. Here, a first opening 101, a second opening, and a receiving cavity 103 may be defined between the second half shell 120 and the first half shell 110. Of course, only one opening may be defined between the second half shell 120 and the first half shell 110.

[0075] In the embodiment of the present application, the structure of the winding member 200 is not limited. For example, the winding member 200 can be a columnar structure. The implementation method of the winding member 200 being rotatably arranged in the accommodation space is not limited. For example, the winding member 200 can be rotatably arranged in the accommodation space through a rotating shaft structure. As an example, a connecting column 121 is provided in the accommodation space, and the winding member 200 has a second connecting hole 201, and the connecting column 121 is passed through the second connecting hole 201 and can rotate in the second connecting hole 201; thereby, the winding member 200 is rotatably arranged in the accommodation space by passing the connecting column 121 through the second connecting hole 201. Here, as Figure 1 As shown, the connecting column 121 can be fixed to the second half shell 120. Of course, the connecting column 121 and the second half shell 120 can also be a structural member; the connecting column 121 can also be connected to the first half shell 110. Here, the connecting column 121 and the first half shell 110 can be connected by screws.

[0076] In the embodiment of the present application, the cable 300 can be stretched at one end to increase its length, or stretched at both ends to increase its length. Figure 7 As shown, the housing 100 has two openings. Here, a first opening 101, a second opening, and a receiving cavity 103 can be defined between the second half shell 120 and the first half shell 110. The cable 300 can include a first end 320 and a second end 330. The first end 320 is connected to the first end of the winding section 310 and is located outside the housing 100 through the first opening 101. The second end 330 is connected to the second end of the winding section 310 and is located outside the housing 100 through the second opening.

[0077] In the embodiment of the present application, the seat 410 of the damper 400 can be fixed to the accommodating cavity 103 by bonding, welding, clamping, etc. The working portion 420 of the damper 400 is rotatably connected to the seat 410. When the working portion 420 rotates relative to the seat 410, a damping force is generated between the working portion 420 and the seat 410. Here, the damping force between the working portion 420 and the seat 410 can be generated by friction, liquid viscosity, gas resistance, and aerodynamic forces.

[0078] In an embodiment of the present application, the rotating member 500 and the working part 420 can be fixedly connected by an adhesive structure and a clamping structure. Here, since the working part 420 is rotatably connected to the seat part 410, the rotating member 500 is rotatably arranged in the accommodating cavity 103 by being connected to the working part 420. As an example, the data line device may also include a connecting structure 900, and the connecting structure 900 may include: a first connecting hole 910 and a connecting part 920. The first connecting hole 910 is arranged axially; the connecting part 920 is inserted into the first connecting hole 910 along the axial direction and is limited to the first connecting hole 910 in the rotation direction; one of the first connecting hole 910 and the connecting part 920 is arranged in the working part 420, and the other of the first connecting hole 910 and the connecting part 920 is arranged in the rotating member 500, so as to facilitate the connection and disassembly of the working part 420 and the rotating member 500. In one application, such as Figure 1 As shown, the first connecting hole 910 is provided on the rotating member 500 , and the connecting portion 920 is provided on the working portion 420 .

[0079] In the embodiment of the present application, the moving member 600 can be movably disposed in the accommodating cavity 103 through structures such as a slideway, a slide rail, a worm gear, etc.

[0080] When the cable 300 is stored, the movable member 600 is in the mating position. At this time, the movable member 600 is rotatably connected to the rotating member 500 and the winding member 200 respectively. When the winding member 200 rotates, since the movable member 600 is mated with the winding member 200, the movable member 600 will rotate as the winding member 200 rotates; since the movable member 600 is also mated with the rotating member 500, the rotating member 500 will rotate as the winding member 200 rotates; since the rotating member 500 is connected to the working part 420, the working part 420 will rotate as the rotating member 500 rotates, and a damping force will be generated between the working part 420 and the seat 410, so that the damping force can be provided by the rotation of the working part 420 to reduce the rotation speed of the winding member 200.

[0081] When the cable 300 is stretched, the movable member 600 is in a separated position. At this time, the movable member 600 is separated from at least one of the rotating member 500 and the winding member 200. Here, the separation of the movable member 600 from at least one of the rotating member 500 and the winding member 200 can be that the movable member 600 is separated from both the rotating member 500 and the winding member 200, or the movable member 600 is separated from the rotating member 500, or the movable member 600 is separated from the winding member 200. When the cable 300 is pulled to rotate the winding member 200, the rotating member 500 will not rotate because the movable member 600 is separated from at least one of the rotating member 500 and the winding member 200; the working portion 420 will not rotate either, and no damping force will be generated between the working portion 420 and the seat 410, thereby allowing the winding member 200 to rotate quickly, so that the cable 300 can quickly extend out of the housing 100 from the at least one opening.

[0082] The implementation mode that moving member 600 and winding member 200 are connected in coordination is not limited.For example, the peripheral side of moving member 600 is provided with the first tooth portion 612, and the peripheral side of winding member 200 is provided with the second tooth portion 231 that is used to mesh with the first tooth portion 612.When the first tooth portion 612 and the second tooth portion 231 mesh, moving member 600 and winding member 200 are connected in coordination.When the first tooth portion 612 and the second tooth portion 231 separate, moving member 600 and winding member 200 separate.For another example, the peripheral side of moving member 600 is provided with the first concavo-convex structure, and the peripheral side of winding member 200 is provided with the second concavo-convex structure that is used to cooperate with the first concavo-convex structure.When the convex portion of the first concavo-convex structure is positioned in the recess of the second concavo-convex structure, moving member 600 and winding member 200 are connected in coordination, and when the first concavo-convex structure and the second concavo-convex structure separate, moving member 600 and winding member 200 separate.

[0083] In some optional implementations of the embodiments of the present application, the data cable device may further include a mating structure 700, which is arranged between the rotating member 500 and the movable member 600; the mating structure 700 is used to make the movable member 600 move axially; in the process of switching from the state of storing the cable 300 to the state of stretching the cable 300, the movable member 600 is used to rotate in a first direction with the winding member 200, and move from the mating position to the separated position through the mating structure 700; in the process of switching from the state of stretching the cable 300 to the state of storing the cable 300, the movable member 600 is used to rotate in a second direction with the winding member 200, and move from the separated position to the mating position through the mating structure 700; the second direction is opposite to the first direction; through the mating structure 700 between the rotating member 500 and the movable member 600, the movable member 600 can automatically switch between the mating position and the separated position, thereby greatly simplifying the structure of the data cable device.

[0084] In this implementation, the first direction and the second direction are not limited. For example, one of the first direction and the second direction is clockwise, and the other of the first direction and the second direction is counterclockwise.

[0085] In this embodiment, the form of the mating structure 700 is not limited. For example, the mating structure 700 may include a spiral groove 710 and a spiral protrusion 720. The spiral groove 710 is arranged axially; the spiral protrusion 720 is arranged coaxially with the spiral groove 710 and is configured to mate with the spiral groove 710; one of the spiral groove 710 and the spiral protrusion 720 is provided on the rotating member 500, and the other of the spiral groove 710 and the spiral protrusion 720 is provided on the moving member 600. When the cable 300 is stored, the movable member 600 and the rotating member 500 are connected by the spiral protrusion 720 and the spiral groove 710. The movable member 600 is also connected with the winding member 200. In the process of switching from the state of storing the cable 300 to the state of stretching the cable 300, the matching structure 700 of the spiral protrusion 720 and the spiral groove 710 can enable the movable member 600 to move axially to the separation position. At this time, at least part of the spiral protrusion 720 is located in the spiral groove 710; when the spiral protrusion 720 is completely outside the spiral groove 710, or when the movable member 600 is separated from the winding member 200, the movable member 600 moves axially to the separation position; at this time, the winding member 200 cannot drive the working part 420 of the damper 400 to rotate through the movable member 600 and the rotating member 500, thereby enabling the cable 300 to be quickly stretched in the state of stretching the cable 300. When the cable 300 is stretched, the entire spiral protrusion 720 is located outside the spiral groove 710, or the movable member 600 is separated from the winding member 200; in the process of switching from the state of stretching the cable 300 to the state of storing the cable 300, part of the spiral protrusion 720 will be located in the spiral groove 710, and the movable member 600 can be moved axially to the mating position through the matching structure 700 of the spiral protrusion 720 and the spiral groove 710. When part of the spiral protrusion 720 is located in the spiral groove 710 and the movable member 600 is also connected to the winding member 200, the movable member 600 moves axially to the mating position; at this time, the winding member 200 can drive the working part 420 of the damper 400 to rotate through the moving part 600 and the rotating member 500, thereby providing a rotational damping force for the winding member 200 through the working part 420 to reduce the rotation speed of the winding member 200.

[0086] In this embodiment, the moving member 600 has a through hole 611 coaxially arranged with the rotating member 500; the rotating member 500 is inserted into the through hole 611; one of the spiral groove 710 and the spiral protrusion 720 is arranged on the inner wall of the through hole 611; and the other of the spiral groove 710 and the spiral protrusion 720 is arranged on the outer side of the rotating member 500. As an example, Figure 3As shown, the spiral groove 710 is provided on the inner wall of the through hole 611 , and the spiral protrusion 720 is provided on the outer side of the rotating member 500 .

[0087] Of course, in other examples, the movable member 600 may also have an axis portion coaxially arranged with the rotating member 500, the axis portion is passed through the hole portion of the rotating member 500, and one of the spiral groove 710 and the spiral protrusion 720 is arranged on the inner wall of the hole portion; the other of the spiral groove 710 and the spiral protrusion 720 is arranged on the outside of the axis portion.

[0088] In this embodiment, the rotating member 500 may include a limiting flange 510, and a first shaft-shaped portion 520 and a second shaft-shaped portion 530 located at both axial ends of the limiting flange 510; the first shaft-shaped portion 520 is connected to the working portion 420, and the second shaft-shaped portion 530 passes through the through hole 611; the limiting flange 510 defines the limit position of the moving member 600 moving from the separated position to the mating position side; the other of the spiral groove 710 and the spiral protrusion 720 is provided on the outer side of the second shaft-shaped portion 530, as shown in FIG. Figure 3 shown.

[0089] Here, the connection method between the first shaft portion 520 and the working portion 420 is similar to the connection method between the rotating member 500 and the working portion 420 described above, and will not be repeated here.

[0090] In this embodiment, the moving member 600 may include a first annular portion 610; the outer circumference of the first annular portion 610 is rotatably connected to the winding member 200; one of the spiral groove 710 and the spiral protrusion 720 is provided on the inner wall of the through hole 611 of the first annular portion 610; Figure 2 and Figure 4 As shown, the data line device may further include: a first elastic member 810, the first elastic member 810 is sleeved on the outside of the second shaft portion 530 and is located between the first annular portion 610 and the housing 100; the first elastic member 810 is used to provide a force for the moving member 600 to move from the separated position to the mating position; in the state of storing the cable 300, the moving member 600 is in the mating position, when an external force pulls at least one end of the winding section 310, the winding member 200 drives the moving member 600, the rotating member 500 and the working portion 420 to rotate, and the moving member 600 is in the mating position. 00 moves from the mating position to the separated position, the first elastic member 810 is deformed and stores energy. At this time, due to the action of the external force, the moving member 600 is in the separated position; when the external force is removed, the deformation force of the first elastic member 810 pushes the moving member 600 to move from the separated position to the mating position. At this time, if the winding member 200 rotates in the second direction toward the storage direction, since the moving member 600 is in the mating position, the winding member 200 drives the moving member 600, the rotating member 500 and the working part 420 to rotate, so as to provide a damping force for the rotation through the working part 420.

[0091] Here, the manner in which the first annular portion 610 is connected to the winding member 200 is similar to the manner in which the moving member 600 is connected to the winding member 200 , and thus will not be described in detail.

[0092] Here, the structure of the first elastic member 810 is not limited. For example, the first elastic member 810 can be a spring.

[0093] Here, as Figure 1 As shown, the shell 100 may include a first wall 111; a portion of the first wall 111 protrudes outward to form a receiving groove 112 on the inner side of the first wall 111; a portion of the rotating member 500 and the first elastic member 810 are located in the receiving groove 112, so that a space for accommodating a portion of the rotating member 500 and the first elastic member 810 is formed by partially protruding outward from the first wall 111, without making the overall size of the first wall 111 larger; thereby miniaturizing the data line device.

[0094] like Figure 1 As shown, the shell 100 may also include: a first limiting wall 113, the first limiting wall 113 is arranged on the outer peripheral side of the rotating part 500; the first end of the first limiting wall 113 is connected to the bottom of the accommodating groove 112, and the second end of the first limiting wall 113 corresponds to the position of the first annular portion 610, which is used to limit the extreme position of the moving part 600 moving from the mating position to the separation position side. After the moving part 600 moves from the mating position to the separation position, the moving part 600 may continue to move. At this time, when the first annular portion 610 contacts the second end of the first limiting wall 113, the first annular portion 610 will not be able to continue to move, thereby preventing the moving part 600 from moving too far in the axial direction.

[0095] Here, the first end of the first limiting wall 113 and the bottom of the accommodating groove 112 can be connected by bonding, welding, screw threads, etc. Of course, the first limiting wall 113 and the bottom of the accommodating groove 112 can also be an integral structure.

[0096] like Figure 1 As shown, the housing 100 may further include: a second limiting wall 114, which is disposed outside the second shaft-shaped portion 530 of the rotating member 500 and is located within the space defined by the first limiting wall 113; a first elastic member 810 is sleeved outside the second limiting wall 114 and is disposed between the bottom of the accommodating groove 112 and the first annular portion 610. By sleeved outside the second limiting wall 114, the first elastic member 810 is prevented from contacting and rubbing with the second shaft-shaped portion 530, thereby allowing the first elastic member 810 to deform more smoothly. At the same time, confining the second shaft-shaped portion 530 of the rotating member 500 within the space defined by the second limiting wall can prevent the rotating member 500 from axial movement.

[0097] Here, the second shaft portion 530 of the rotating member 500 may be in contact with the bottom of the receiving groove 112 or may have a small gap therebetween.

[0098] Here, the second limiting wall 114 and the bottom of the accommodating groove 112 can be connected by bonding, welding, screw threads, etc. Of course, the second limiting wall 114 and the bottom of the accommodating groove 112 can also be an integrated structure.

[0099] Of course, in other implementations, the housing 100 may not be provided with the second limiting wall 114 or the first limiting wall 113, and the first elastic member 810 may be provided between the rotating member 500 and the housing 100; the first elastic member 810 is used to provide a force to move the rotating member 500 from the separated position to the engaged position. Of course, the first wall 111 of the housing 100 may not be protruding outward.

[0100] like Figure 1 and Figure 2 As shown, the movable member 600 may further include a cylindrical portion 620 coaxially arranged with the first annular portion 610; the inner diameter of the cylindrical portion 620 is larger than the diameter of the through hole 611 of the first annular portion 610; one end of the first elastic member 810 is located in the limiting groove 601 defined by the cylindrical portion 620 and the first annular portion 610, thereby preventing the first elastic member 810 from deflecting in the radial direction and ensuring the stability of the position of the first elastic member 810 to provide a more stable deformation force.

[0101] Of course, in other implementations, the data line device may not be provided with the first elastic member 810. In this case, the movable member 600 can be moved from the separated position to the mating position by an external force. For example, the data line device may further include an operating member, a first end of the operating member being connected to the movable member 600, and a second end of the operating member extending outside the housing 100. In this case, the movable member 600 can be switched between the separated position and the mating position by operating the second end of the operating member with an external force. Here, the mating structure 700 is a spiral groove 710 and a spiral protrusion 720. The second end of the operating member operated by an external force causes the movable member 600 to rotate and move axially. Of course, the mating structure 700 may also be a concave-convex mating structure 700 or a gear mating structure 700. The second end of the operating member operated by an external force can cause the movable member 600 to move only axially, thereby achieving both movement in the separated position and switching between the mating position. For another example, the data line device may further include a motor, a worm may be provided on the movable member 600, a turbine may be provided on the drive shaft of the motor, the turbine and the worm are meshed, and the motor can drive the turbine to rotate so that the movable member 600 moves only in the axial direction to achieve switching between the separated position and the mating position. For another example, the data line device may further include a motor, the movable member 600 may be connected to a first gear, the drive shaft of the motor may be connected to a second gear, the first gear and the second gear are meshed, and the motor can drive the movable member 600 to rotate and move in the axial direction through the first gear and the second gear. In this case, the mating structure 700 may be a spiral groove 710 and a spiral protrusion 720.

[0102] In some optional implementations of the embodiments of the present application, such as Figure 5 As shown, the winding member 200 may include a winding portion 210 , a plate portion 220 and a matching portion 230 arranged along the axial direction; the winding section 310 is wound around the winding portion 210 ; and the matching portion 230 is matched and connected with the moving member 600 .

[0103] In this implementation, the matching portion 230 is connected to the movable member 600 in a manner similar to the above-mentioned winding member 200 and movable member 600, and will not be described in detail herein. As an example, the outer peripheral side of the matching portion 230 is connected to the movable member 600. In one application, the outer peripheral side of the matching portion 230 is provided with a second tooth portion 231.

[0104] In this implementation, if Figure 6As shown, the winding portion 210 can be ring-shaped, and the data cable device can also include: a second elastic member 830, at least part of which is arranged in the cavity of the winding portion 210 and is respectively connected to the winding portion 210 and the shell 100; the second elastic member 830 is used to provide a force for the winding member 200 to rotate in the storage direction, so that when the external force for stretching the cable 300 is removed, the winding member 200 is automatically rotated in the storage direction based on the force for rotation in the storage direction provided by the second elastic member 830, thereby realizing automatic storage of the cable 300 by the data cable device.

[0105] Here, the structure of the second elastic member 830 is not limited. For example, the second elastic member 830 can be a coil spring.

[0106] The manner in which the second elastic member 830 is connected to the winding portion 210 and the housing 100 is not limited. For example, the first end of the second elastic member 830 can be fixed to the winding portion 210 by snapping, bonding, welding, etc., and the second end of the second elastic member 830 can be fixed to the housing 100 by snapping, bonding, welding, etc. As an example, the second end of the second elastic member 830 is fixed to the housing 100 by snapping onto the connecting post 121.

[0107] Here, as Figure 8 As shown, the data cable device may further include a baffle 840 disposed between the second elastic member 830 and the housing, so that the second elastic member 830 is stably located in the cavity of the winding portion 210 .

[0108] In this implementation, the data cable device may further include: a limit member 820, which is arranged between the shell 100 and the end side of the mating portion 230; the limit member 820 is used to limit the rotation position of the winding member 200 relative to the shell 100, so that when the cable 300 is pulled out of the shell 100 to a suitable length, the limit member 820 can be used to prevent the winding member 200 from rotating relative to the shell 100, thereby keeping the cable 300 at a suitable length.

[0109] The structure of the limiting member 820 is not limited. Figure 5 and Figure 8As shown, the end face side of the matching portion 230 is further provided with an inner annular slideway 232 and an outer annular slideway 233 arranged at intervals along the radial direction, as well as a slide-in channel 234 and a slide-out channel 235 respectively connected to the inner annular slideway 232 and the outer annular slideway 233. The end face side of the matching portion 230 is further provided with a card slot 236 at the slide-in channel 234; the limiting member 820 is rotatably provided on the housing 100 and has a boss 821 arranged along the axial direction, and the boss 821 is used to be clamped in the card slot 236; when the cable 300 is stretched by an external force, the boss 821 is used to be clamped in the card slot 236. The column 821 slides in the inner annular slide 232, and when the cable 300 is stretched to an appropriate length; the external force is removed, the winding member 200 rotates in the opposite direction under the action of the second elastic member 830, and the boss 821 enters the card slot 236 from the sliding channel 234, and the winding member 200 no longer rotates; when the winding member 200 is lightly pulled and released, the boss 821 enters the outer annular slide 233 from the sliding channel 234, and rotates in the opposite direction under the action of the second elastic member 830, and the boss 821 slides in the outer annular slide 233 until the cable 300 is completely stored.

[0110] Here, the limiting member 820 may be rotatably disposed on the housing 100 via a rotating shaft structure. As an example, the limiting member 820 may be rotatably connected to the housing 100 via a shaft hole structure.

[0111] Of course, in other implementations, the limiting member 820 may also have other structures. For example, the limiting member 820 may be movably disposed on the housing 100, and a limiting groove that cooperates with the limiting member 820 may be disposed on the end side of the mating portion 230. When the end of the limiting member 820 moves into the limiting groove, the winding member 200 cannot rotate. When the end of the limiting member 820 moves out of the limiting groove, the winding member 200 can rotate.

[0112] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
