DETAILED DESCRIPTION

[0064] The technical solution of the present application is further elaborated in detail below with reference to the accompanying drawings and specific embodiments.

[0065] 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.

[0066] 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.

[0067] The following combination Figures 1 to 8 The data line device described in the embodiments of the present application is described in detail.

[0068] In an embodiment of the present application, a data line device includes: a housing 100, a winding member 200, a cable 300, a damper 400, a rotating member 600, and a moving member 500. The housing 100 has a receiving cavity 102 and at least one opening communicating with the receiving cavity 102; the winding member 200 is rotatably disposed in the receiving cavity 102; 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 housing 100 through at least one opening; the damper 400 includes a seat 410 and a working portion 420 rotatably connected to the seat 410; the seat 410 is fixed in the receiving cavity 102; the rotating member 420 is fixed to ... The component 600 is rotatably connected with the winding component 200 in the accommodating cavity 102; the movable component 500 is axially movably arranged in the accommodating cavity 102, and has a matching position respectively connected with the rotating component 600 and the working part 420, and a separated position separated from at least one of the rotating component 600 and the working part 420; in the state of storing the cable 300, the movable component 500 is in the matching position to rotate the working part 420 to provide a damping force; in the state of stretching the cable 300, the movable component 500 is in the separated position.

[0069] In the related art, the data cable structure includes a shell structure, a rotating structure, and a cable structure; the rotating structure is used to stretch and store the cable structure. However, the cable structure stores 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 500 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.

[0070] 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 102 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.

[0071] 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.

[0072] 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 102 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.

[0073] In the embodiment of the present application, the seat 410 of the damper 400 can be fixed to the accommodating cavity 102 by bonding, welding, clamping, or the like. 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. The damping force between the working portion 420 and the seat 410 can be generated by friction, liquid viscosity, gas resistance, and aerodynamic forces.

[0074] In the embodiment of the present application, the implementation method of the cooperative connection between the rotating member 600 and the winding member 200 is not limited. For example, the outer peripheral side of the rotating member 600 is provided with a first tooth portion 612, and the outer peripheral side of the winding member 200 is provided with a second tooth portion 231 for engaging with the first tooth portion 612. The first tooth portion 612 and the second tooth portion 231 are engaged with each other to achieve the cooperative connection between the rotating member 600 and the winding member 200. For another example, the outer peripheral side of the rotating member 600 is provided with a first concave-convex structure, and the outer peripheral side of the winding member 200 is provided with a second concave-convex structure for cooperating with the first concave-convex structure. The convex portion of the first concave-convex structure is located in the concave portion of the second concave-convex structure to achieve the cooperative connection between the rotating member 600 and the winding member 200.

[0075] In the embodiment of the present application, the moving member 500 can be movably disposed in the accommodating cavity 102 through structures such as a slideway, a slide rail, a worm gear, etc.

[0076] When the cable 300 is stored, the movable member 500 is in the mating position. At this time, the movable member 500 is respectively connected with the rotating member 600 and the working part 420. When the winding member 200 rotates, since the rotating member 600 is rotatably connected with the winding member 200, the rotating member 600 will rotate as the winding member 200 rotates; since the movable member 500 is also connected with the rotating member 600, the movable member 500 will rotate as the rotating member 600 rotates; since the movable member 500 is connected with the working part 420, the working part 420 will rotate as the movable 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.

[0077] When the cable 300 is stretched, the moving member 500 is in a separated position. At this time, the moving member 500 is separated from at least one of the rotating member 600 and the working portion 420. Here, the separation of the moving member 500 from at least one of the rotating member 600 and the working portion 420 can mean that the moving member 500 is separated from both the rotating member 600 and the working portion 420, the moving member 500 is separated from the rotating member 600, or the moving member 500 is separated from the working portion 420. When the cable 300 is pulled to rotate the winding member 200, since the moving member 500 is separated from at least one of the rotating member 600 and the working portion 420, the working portion 420 does not rotate, and no damping force is generated between the working portion 420 and the seat 410, thereby enabling the working portion 420 to rotate rapidly, so that the cable 300 can be quickly extended out of the housing 100 from the at least one opening.

[0078] There is no limitation on the way in which the moving part 500 is connected to the working part 420. As long as the moving part 500 and the working part 420 can be in a state of being connected in a coordinated manner, and can also be in a state of being separated. For example, the data line device may further 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 used to be inserted into the first connecting hole 910 along the axial direction, and is used to be limited in 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 moving part 500, so as to facilitate the coordinated connection and separation of the working part 420 and the moving part 500. In one application, such as Figure 1 As shown, the first connecting hole 910 is arranged on the working part 420, and the connecting part 920 is arranged on the moving part 500. Here, the cross section of the working part 420 can be non-circular, and the cross section of the first connecting hole 910 can be non-circular. For another example, the moving part 500 has a third matching portion, and the working part 420 has a fourth matching portion. The third matching portion and the fourth matching portion can be connected in conjunction with each other, or can be separated. The third matching portion and the fourth matching portion can be a gear structure that can be matched, or can be a concave-convex structure that can be matched.

[0079] In some optional implementations of the embodiments of the present application, the data cable device may further include: a matching structure 700, the matching structure 700 being arranged between the rotating member 600 and the movable member 500; the matching structure 700 being used to move the movable member 500 in the axial direction; in the process of switching from the state of storing the cable 300 to the state of stretching the cable 300, the rotating member 600 is used to rotate in a first direction along with the winding member 200, and the movable member 500 is used to move from the matching position to the separated position through the matching structure 700; in the process of switching from the state of stretching the cable 300 to the state of storing the cable 300, the rotating member 600 is used to rotate in a second direction along with the winding member 200, and the movable member 500 is used to move from the separated position to the matching position through the matching structure 700; the second direction is opposite to the first direction. Through the matching structure 700 between the rotating member 600 and the movable member 500, the movable member 500 can automatically switch between the matching position and the separated position, thereby greatly simplifying the structure of the data cable device.

[0080] 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.

[0081] 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 600, and the other of the spiral groove 710 and the spiral protrusion 720 is provided on the moving member 500. When the cable 300 is stored, the movable member 500 and the rotating member 600 are connected by the spiral protrusion 720 and the spiral groove 710, and the rotating member 600 is also connected by 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 500 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 500 is separated from the working part 420, the movable member 500 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 500 and the rotating member 600, 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 part 500 is separated from the working part 420; 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 part 500 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 part 500 is also connected to the working part 420, the movable part 500 moves axially to the mating position; at this time, the winding part 200 can drive the working part 420 of the damper 400 to rotate through the moving part 500 and the rotating part 600, thereby providing a rotational damping force for the winding part 200 through the working part 420 to reduce the rotation speed of the winding part 200.

[0082] In this embodiment, the rotating member 600 has a through hole 611 coaxially arranged with the moving member 500; one end of the moving member 500 passes through the through hole 611 and corresponds to the position of the working portion 420; one of the spiral groove 710 and the spiral protrusion 720 is arranged on the inner wall of the through hole 611; the other of the spiral groove 710 and the spiral protrusion 720 is arranged on the outer side of the moving member 500. As an example, Figure 3 As 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 600 .

[0083] Of course, in other examples, the rotating member 600 may also have an axis portion coaxially arranged with the moving member 500, the axis portion is passed through the hole portion of the moving 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.

[0084] In this implementation, if Figure 1 As shown, the seat 410 has a mounting groove 411. Figure 2 As shown, the rotating member 600 includes a first matching portion 610, and a first cylindrical portion 630 and a second cylindrical portion 620 located at both axial ends of the first matching portion 610, and the first matching portion 610 is rotatably matched with the winding member 200; the through hole 611 is at least provided in the first matching portion 610, and the first cylindrical portion 630 is rotatably inserted in the mounting groove 411 to realize that the rotating member 600 is rotatably provided in the accommodating cavity 102.

[0085] Here, the rotatable matching connection between the first matching portion 610 and the winding member 200 is similar to the rotatable matching connection between the rotating member 600 and the winding member 200, and is not repeated here.

[0086] In the implementation, Figure 3 As shown, the movable member 500 includes a limiting flange 510, and a first shaft-like portion 520 and a second shaft-like portion 530 located at both axial ends of the limiting flange 510, and the other of the spiral groove 710 and the spiral protrusion 720 is arranged on the outside of the first shaft-like portion 520, and the first shaft-like portion 520 passes through the through hole 611 and corresponds to the position of the working portion 420; the first shaft-like portion 520 and the working portion 420 can be connected in cooperation or separated, and the implementation method of the cooperation connection between the first shaft-like portion 520 and the working portion 420 is similar to the cooperation connection method between the above-mentioned movable member 500 and the working portion 420, which will not be repeated here.

[0087] In an implementation, the data line device may further include: a first elastic member 810, the first elastic member 810 being sleeved on the outside of the second shaft-shaped portion 530 and being located between the limiting flange 510 and the housing 100; the first elastic member 810 being used to provide a force for the moving member 500 to move from the separated position to the engaged position, in the state of storing the cable 300, as shown in FIG. Figure 1 and Figure 4As shown, the movable member 500 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 rotating member 600, the movable member 500 and the working part 420 to rotate, and the movable member 500 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 movable member 500 is in the separated position; when the external force is removed, the deformation force of the first elastic member 810 pushes the movable member 500 from the separated position to the mating position. At this time, if the winding member 200 rotates in the second direction to the storage direction, since the movable member 500 is in the mating position, the winding member 200 drives the rotating member 600, the movable member 500 and the working part 420 to rotate, so as to provide a damping force for the rotation through the working part 420.

[0088] Here, the structure of the first elastic member 810 is not limited. For example, the first elastic member 810 can be a spring.

[0089] In this implementation, if Figure 1 and Figure 7 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 movable 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 movable 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.

[0090] 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 movable part 500; the first end of the first limiting wall 113 is connected to the bottom of the accommodating groove 112, and the second cylindrical portion 620 of the rotating part 600 is inserted in the space defined by the second end of the first limiting wall 113, and the first matching portion 610 of the rotating part 600 is axially limited between the first limiting wall 113 and the seat portion 410, so as to prevent the rotating part 600 from moving in the axial direction by the first limiting wall 113 and the seat portion 410.

[0091] 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.

[0092] like Figure 1As shown, the housing 100 may further include: a second limiting wall 114, the second limiting wall 114 being arranged outside the second shaft-shaped portion 530 of the moving member 500 and being located in the space defined by the first limiting wall 113; the first elastic member 810 being sleeved outside the second limiting wall 114 and being arranged between the bottom of the accommodating groove 112 and the limiting flange 510 of the moving member 500. By sleeved the first elastic member 810 outside the second limiting wall 114, it is possible to prevent the first elastic member 810 from contacting and rubbing with the second shaft-shaped portion 530, thereby making the first elastic member 810 deform more smoothly. At the same time, by limiting the second shaft-shaped portion 530 of the moving member 500 in the space defined by the second limiting wall 114, it is possible to provide a guiding effect for the movement of the moving member 500 through the second limiting wall 114.

[0093] 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.

[0094] 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 600 and the housing 100; the first elastic member 810 is used to provide a force to move the movable 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.

[0095] In some optional implementations of the embodiments of the present application, the winding member 200 may include a winding portion 210, a plate-shaped portion 220 and a second matching portion 230 arranged along the axial direction; the winding section 310 is wound around the winding portion 210; the second matching portion 230 is matched and connected with the first matching portion 610 of the rotating member 600.

[0096] In this embodiment, the second mating portion 230 is mated with the first mating portion 610 of the rotating member 600 in a manner similar to the mating connection between the winding member 200 and the rotating member 600 described above, and will not be further described here. As an example, the outer periphery of the second mating portion 230 is mated with the first mating portion 610 of the rotating member 600. In one application, the outer periphery of the second mating portion 230 is provided with a first tooth portion 612, and the outer periphery of the first mating portion 610 of the rotating member 600 is provided with a second tooth portion 231 that meshes with the first tooth portion 612.

[0097] In this implementation, if Figure 6As shown, the winding portion 210 is annular, and the data cable device may further 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 rotating the winding member 200 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 rotating in the storage direction provided by the second elastic member 830, thereby realizing automatic storage of the cable 300 by the data cable device.

[0098] Here, the structure of the second elastic member 830 is not limited. For example, the second elastic member 830 can be a coil spring.

[0099] 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.

[0100] 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 100 , so that the second elastic member 830 is stably located in the cavity of the winding portion 210 .

[0101] 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 second 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.

[0102] The structure of the limiting member 820 is not limited. Figure 5 and Figure 8As shown, the end face side of the second fitting part 230 is also provided with an inner annular slide 232 and an outer annular slide 233 arranged along the radial interval, and a slide-in channel 234 and a slide-out channel 235 respectively connected to the inner annular slide 232 and the outer annular slide 233, and the end face side of the second fitting part 230 is also provided with a card slot 236 at the slide-in channel 234; the limit member 820 is rotatably arranged on the shell 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 external force, the boss 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.

[0103] 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.

[0104] 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 surface of the second 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.

[0105] 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.
