DETAILED DESCRIPTION

[0040] The technical solution of the present application is further elaborated in detail below with reference to the accompanying drawings and specific embodiments.

[0041] 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.

[0042] 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.

[0043] The following combination Figures 1 to 6 The data line device described in the embodiments of the present application is described in detail.

[0044] In an embodiment of the present application, a data cable device includes a housing 100, a winding member 200, a cable 300, and a damping assembly 400. 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; the winding member 200 includes an axially arranged winding portion 210 and a first mating portion 230; 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 portion 210; at least one end is connected to the winding section 310 and is located outside the shell 100 through at least one opening; the damping assembly 400 includes a seat body 410 and a second matching portion 420 rotatably connected to the seat body 410; the seat body 410 is fixed in the accommodating cavity 103; the second matching portion 420 is matched and connected with the first matching portion 230; in the state of stretching the cable 300, there is a first damping force between the second matching portion 420 and the seat body 410; in the state of storing the cable 300, there is a second damping force between the second matching portion 420 and the seat body 410; the value of the second damping force is greater than the value of the first damping force.

[0045] In the related art, a data cable structure includes a shell structure, a rotating structure, and a cable structure; the rotating structure is used to stretch and retract the cable structure. However, the cable retraction speed is relatively fast, which can easily injure the user. In the data cable device of the present application, when the cable 300 is retracted, a second damping force is generated between the second mating portion 420 and the base 410. Because the second mating portion 420 is mated with the first mating portion 230, the first mating portion 230 provides a second damping force for the winding member 200 to rotate in the direction of retracting the cable 300. This significantly reduces the speed at which the winding member 200 rotates in the retracting direction, thereby preventing the cable 300 from being retracted quickly and injuring the user. Furthermore, because the second damping force is greater than the first damping force, the first damping force is relatively small. Therefore, when the cable 300 is stretched, the damping assembly 400 does not generate too much damping force, making it easier to pull the cable 300 in the stretched state.

[0046] In the embodiments of the present application, the structure of the housing 100 is not limited. For example, in some embodiments, the housing 100 may be a rectangular parallelepiped structure. For another example, in other embodiments, the housing 100 may be an elliptical structure.

[0047] As an example, Figure 2 and Figure 6As shown, the housing 100 may include a first half shell 110 and a second half shell 120. The second half shell 120 may be fixedly 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 102, and a receiving cavity 103 may be defined between the second half shell 120 and the first half shell 110. Of course, in other examples, only one opening may be defined between the second half shell 120 and the first half shell 110.

[0048] In the embodiments of the present application, the structure of the winding member 200 is not limited. For example, in some embodiments, the winding member 200 can be a columnar structure. For example, in other embodiments, the winding member 200 can be a ring structure.

[0049] The implementation method of the winding member 200 being rotatably disposed in the accommodating space is not limited. For example, in some embodiments, the winding member 200 can be rotatably disposed in the accommodating space through a rotating shaft structure. As an example, a connecting column 121 can be provided in the accommodating space, and the winding member 200 can have a first connecting hole 201, and the connecting column 121 is passed through the first connecting hole 201 and can rotate in the first connecting hole 201; thereby, the winding member 200 can be rotatably disposed in the accommodating space by passing the connecting column 121 through the first connecting hole 201. Here, as Figure 3 and Figure 6 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 component; here, the connecting column 121 and the second half shell 120 can be integrally formed by injection molding. Here, 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 a first fastener 710. The structure of the first fastener 710 is not limited. For example, the first fastener 710 can be a screw. Of course, the connecting column 121 can also be fixed to the first half shell 110. The connecting column 121 and the first half shell 110 can also be a structural component; here, the connecting column 121 and the first half shell 110 can also be integrally formed by injection molding.

[0050] Here, the structures of the winding portion 210 and the first matching portion 230 are not limited. For example, in some embodiments, the winding portion 210 and the first matching portion 230 can be different parts on the same columnar structure. As an example, the winding portion 210 and the first matching portion 230 can be columnar structures of different diameters. For another example, in other embodiments, the winding portion 210 and the first matching portion 230 can be different parts on the same annular structure. As an example, Figure 3 and Figure 5 As shown, the winding portion 210 and the first matching portion 230 can be annular structures with different diameters.

[0051] 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 1 As shown, the housing 100 has two openings. Here, a first opening 101, a second opening 102, 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 102. Here, the winding section 310, the first end 320, and the second end 330 can be different parts of the same wire.

[0052] In the embodiment of the present application, when the cable 300 is stored, the damping assembly 400 is used to provide a rotational damping force for the winding member 200. The structure of the damping assembly 400 is similar to that of a one-way damper, and the manner in which the damping assembly 400 generates the damping force is similar to that of a one-way damper, and will not be further described here.

[0053] The structure of the seat 410 is not limited. For example, in some embodiments, the seat 410 may be a block structure. For another example, in other embodiments, the seat 410 may be a plate structure. The seat 410 may be fixed in the accommodating cavity 103 by bonding, welding, clamping, etc. As an example, Figure 1 and Figure 6 As shown, the base 410 can be fixed to the second housing 100 by two second fasteners 720. The structure of the second fasteners 720 is not limited. For example, the second fasteners 720 can be screws.

[0054] The second matching portion 420 can be rotatably connected to the base body 410 via a rotating shaft structure. Figure 1 and Figure 6As shown, the damping assembly 400 may further include: a rotating shaft 430 rotatably connected to the base 410; and a second mating portion 420 circumferentially fixed to the rotating shaft 430. The second mating portion 420 is rotatably connected to the base 410 via the rotating shaft 430. When the cable 300 is stretched, a first damping force is generated between the rotating shaft 430 and the base 410; when the cable 300 is stored, a second damping force is generated between the rotating shaft 430 and the base 410. When the cable 300 is stored, a relatively large damping force is generated between the rotating shaft 430 and the base 410 during rotation of the rotating shaft 430 relative to the base 410. The damping force between the rotating shaft 430 and the base 410 can be generated by friction, liquid viscosity, gas resistance, and aerodynamic forces. The rotating shaft 430 is rotatably connected to the base 410 via a second connection hole inserted into the base 410. The second mating portion 420 can be circumferentially secured to the rotating shaft 430 by means of snapping, welding, or bonding. In one application, the second mating portion 420 has a slot 422. The first end of the rotating shaft 430 is rotatably disposed in the base 410, and the second end of the rotating shaft 430 is inserted into the slot 422. This allows the second mating portion 420 to be circumferentially secured to the rotating shaft 430 and facilitates quick connection between the second end of the rotating shaft 430 and the second mating portion 420. Here, the cross-section of the slot 422 is non-circular, and the cross-section of the second end of the rotating shaft 430 is also non-circular. Of course, in other examples, the rotating shaft 430 and the second mating portion 420 may also be different parts of a single structural component.

[0055] The value of the first damping force is not limited. For example, the value of the first damping force is zero, and here, the damping assembly 400 is similar to a one-way damper. For another example, the value of the first damping force is greater than zero, so that the first damping force can provide the user with the feel of stretching the cable 300. As an example, when the cable 300 is stretched, the first damping force between the rotating shaft 430 and the base 410 is small due to low friction, low liquid viscosity, and low gas resistance; when the cable 300 is stored, the second damping force between the rotating shaft 430 and the base 410 is large due to high friction, high liquid viscosity, and high gas resistance.

[0056] Here, the manner in which the second matching portion 420 is connected to the first matching portion 230 is not limited. Figure 1As shown, the outer periphery of the first mating portion 230 has at least two first teeth 231, and the outer periphery of the second mating portion 420 has at least two second teeth 421; the first teeth 231 and the second teeth 421 engage to achieve a mating connection between the second mating portion 420 and the first mating portion 230. For example, in other embodiments, the outer periphery of the first mating portion 230 has a first concave-convex structure, and the outer periphery of the second mating portion 420 has a second concave-convex structure; the convex portion of the first concave-convex structure is located within the concave portion of the second concave-convex structure, to achieve a mating connection between the second mating portion 420 and the first mating portion 230.

[0057] In some optional implementations of the embodiments of the present application, such as Figure 3 and Figure 5 As shown, the winding portion 210 can be annular, and the winding section 310 is used to be wound around the outer periphery of the winding portion 210. The data cable device can also include: an elastic member 500, at least a portion of which is disposed within the cavity defined by the winding portion 210 and is connected to the winding portion 210 and the housing 100 respectively; the elastic member 500 is used to provide a force to the winding member 200 to rotate in the storage direction; so that the elastic member 500 can automatically rotate the winding member 200 in the storage direction to automatically store the cable 300. At the same time, because the winding section 310 can be wound around the outer periphery of the winding portion 210 and at least a portion of the elastic member 500 is disposed within the cavity defined by the winding portion 210, the axial installation space of the elastic member 500 can be reduced, thereby reducing the axial installation size of the data cable device.

[0058] In this implementation, the structure of the elastic member 500 is not limited. For example, in some embodiments, the elastic member 500 can be a coil spring.

[0059] The manner in which the elastic member 500 is connected to the winding portion 210 and the housing 100 is not limited. For example, in some embodiments, the first end of the elastic member 500 can be fixed to the winding portion 210 by snapping, bonding, welding, etc., and the second end of the elastic member 500 can be fixed to the housing 100 by snapping, bonding, welding, etc. As an example, the second end of the elastic member 500 is fixed to the housing 100 by snapping onto the connecting post 121.

[0060] 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 first matching portion 230 arranged along the axial direction; the winding portion 210 and the first matching portion 230 are located on opposite sides of the plate-shaped portion 220, so that the winding portion 210 and the first matching portion 230 are separated by the plate-shaped portion 220 to prevent the winding segment 310 of the cable 300 from rubbing against the first matching portion 230 and damaging the winding segment 310 of the cable 300 when the cable 300 is stretched or when the cable 300 is stored.

[0061] like Figure 3 As shown, in this embodiment, the shape of the first mating portion 230 is not limited. For example, the first mating portion 230 can be annular, with the outer periphery of the first mating portion 230 mating with the outer periphery of the second mating portion 420. The housing 100 can include a first wall 111. A first portion of the first wall 111 is recessed inward to form a raised portion 112 on the inner side of the first wall 111. The raised portion 112 is partially located within the cavity defined by the first mating portion 230, thereby reducing the installation space of the housing 100. At the same time, the annular shape of the first mating portion 230 can also reduce the installation area of ​​the first mating portion 230, thereby reducing the volume and weight of the winding member 200, thereby achieving a lightweight data cable device.

[0062] Here, as Figure 3 As shown, the first wall 111 may be located in the first shell 100 .

[0063] In this implementation, the data cable device may further include: a limit member 600, which is arranged between the end side of the protrusion 112 and the plate-shaped portion 220; the limit member 600 is used to limit the rotation position of the winding member 200 relative to the shell 100. Since the limit member 600 is arranged between the end side of the protrusion 112 and the plate-shaped portion 220, the limit member 600 and the first matching portion 230 can be axially located in substantially the same plane space. Here, at least part of the limit member 600 is located in the space defined by the first matching portion 230, thereby reducing the axial setting space of the limit member 600, thereby reducing the axial setting size of the data cable device, and reducing the setting volume and weight of the limit member 600.

[0064] Of course, in other examples, the limiting member 600 may also be disposed between the first shell 100 and the first matching portion 230 . Here, the first matching portion 230 may be a columnar structure, and the first portion of the first wall 111 may not be recessed inward.

[0065] Here, when the cable 300 is pulled out of the housing 100 to a suitable length, the limiting member 600 can prevent the winding member 200 from rotating relative to the housing 100, thereby keeping the cable 300 at a suitable length.

[0066] The structure of the limiting member 600 is not limited. Figure 1 and Figure 4 As shown, the end surface side of the plate-like portion 220 is further provided with an inner annular slideway 221 and an outer annular slideway 222 spaced apart in the radial direction, as well as a slide-in channel 223 and a slide-out channel 224 respectively connected to the inner annular slideway 221 and the outer annular slideway 222. The end surface side of the plate-like portion 220 is further provided with a slot 225 at the slide-in channel 223.

[0067] The limiting member 600 is rotatably disposed on the raised portion 112 and has an axially disposed boss 610, which is used to be locked in the slot 225. When an external force is applied to stretch the cable 300, the boss 610 slides in the inner annular slideway 221. When the cable 300 is stretched to a suitable length, the external force is removed and the winding member 200 rotates in the opposite direction under the action of the elastic member 500. The boss 610 enters the slot 225 from the sliding channel, and the winding member 200 stops rotating. When the winding member 200 is gently pulled and released, the boss 610 enters the outer annular slideway 222 from the sliding channel and rotates in the opposite direction under the action of the elastic member 500. The boss 610 slides in the outer annular slideway 222 until the cable 300 is completely stored.

[0068] Here, the limiting member 600 can be rotatably disposed on the protruding portion 112 via a rotating shaft structure. As an example, the limiting member 600 can be rotatably connected to the housing 100 via a shaft hole structure.

[0069] Of course, in other implementations, the limiting member 600 may also have other structures. For example, the limiting member 600 may be movably disposed on the housing 100, and a limiting groove that cooperates with the limiting member 600 may be disposed on the end surface of the plate-shaped portion 220 or the end surface of the first matching portion 230. When the end of the limiting member 600 moves into the limiting groove, the winding member 200 cannot rotate. When the end of the limiting member 600 moves out of the limiting groove, the winding member 200 can rotate.

[0070] The various specific technical features described in the specific embodiments may be combined in any suitable manner, unless they are inconsistent. For example, different embodiments and technical solutions may be formed by combining different specific technical features. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this utility model will not be described separately.

[0071] 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.
