Detailed Implementation

[0060] The technical solution of this application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0061] In the embodiments described in this application, it should be noted that, unless otherwise stated and limited, the term "connection" should be interpreted broadly. For example, it can be an electrical connection, or a connection between two internal components. It can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above term according to the specific circumstances.

[0062] It should be noted that the terms "first," "second," and "third" used in the embodiments of this application are merely used to distinguish similar objects and do not represent a specific ordering of objects. It is understood that "first," "second," and "third" can be interchanged in a specific order or sequence where permitted. It should be understood that the objects distinguished by "first," "second," and "third" can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in an order other than those illustrated or described herein.

[0063] The following combination Figures 1 to 5 The data cable device described in the embodiments of this application will be described in detail.

[0064] In embodiments of this application, the data cable device includes: a housing 100, a winding member 200, a cable 300, a functional component 600, a positioning component 500, and a damping component 400. The housing 100 has a receiving cavity 101 and at least one opening 102 communicating with the receiving cavity 101; the winding member 200 is rotatably disposed within the receiving cavity 101; the cable 300 includes: a winding section 310 and at least one end. A winding segment 310 is used to wind the winding member 200; at least one end is connected to the winding segment 310 and is located outside the housing 100 through at least one opening 102; a functional member 600 is disposed on the end side of the winding member 200; a positioning assembly 500 is movably disposed on the housing 100; the positioning assembly 500 has a first position relative to the housing 100 that is engaged with the functional member 600 and a second position that is separated from the functional member 600; in the first position, the winding member 200 is fixed by the position of the functional member 600 relative to the housing 100; a damping assembly 400 is disposed on the housing 100; the damping assembly 400 is used to cooperate with the functional member 600 to provide a rotational damping force to the winding member 200.

[0065] In related technologies, data cable structures include a shell structure, a rotating structure, a cable structure, and a damping structure. The rotating structure enables the cable to be stretched and retracted, while the damping structure reduces the rotational speed of the cable. However, the complexity of the damping structure affects the adaptability of the data cable device. In the data cable device of this application, the functional component 600 is used both to connect with the positioning component 500 to position the winding component 200 and to cooperate with the damping component 400 to provide rotational damping force to the winding component 200. The functional component 600 realizes the functions of both structures, thereby greatly simplifying the structure of the data cable device and improving its adaptability.

[0066] In the embodiments of this application, the structure of the housing 100 is not limited. For example, in some embodiments, the housing 100 can be a cuboid structure. In other embodiments, the housing 100 can be an elliptical structure.

[0067] As an example, such as Figure 3 and Figure 4 As shown, the housing 100 may include a first half-shell 110 and a second half-shell 120, which are fixedly connected to the first half-shell 110 by means of a snap-fit ​​structure, a threaded structure, an adhesive structure, etc. Here, an opening 102 and a receiving cavity 101 may be defined between the second half-shell 120 and the first half-shell 110. Of course, in some other examples, two openings may also be defined between the second half-shell 120 and the first half-shell 110.

[0068] In the embodiments of this 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. In other embodiments, the winding member 200 can be a ring-shaped structure.

[0069] The implementation method in which the winding member 200 is rotatably disposed within the receiving cavity 101 is not limited. For example, in some embodiments, the winding member 200 can be rotatably disposed within the receiving cavity 101 via a rotating shaft structure. As an example, a connecting post 121 can be provided within the receiving cavity 101, and the winding member 200 can have a first connecting hole 201, with the connecting post 121 passing through and rotating within the first connecting hole 201; thereby, the winding member 200 is rotatably disposed within the receiving cavity 101 by the connecting post 121 passing through the first connecting hole 201. Here, as... Figure 1 and Figure 5As shown, the connecting post 121 can be fixed to the second half-shell 120. Alternatively, the connecting post 121 and the second half-shell 120 can be a single structural component; here, the connecting post 121 and the second half-shell 120 can be integrally molded by injection molding. The connecting post 121 can also be connected to the first half-shell 110, and the connecting post 121 and the first half-shell 110 can be connected by a fastener 740. The structure of the fastener 740 is not limited. For example, the fastener 740 can be a screw. Alternatively, the connecting post 121 can also be fixed to the first half-shell 110, and the connecting post 121 and the first half-shell 110 can be a single structural component; here, the connecting post 121 and the first half-shell 110 can also be integrally molded by injection molding.

[0070] In this embodiment, the length of the cable 300 can be increased by stretching one end or by stretching both ends. As an example, such as... Figure 3 and Figure 4 As shown, the housing 100 has an opening 102, which defines an opening 102 and a receiving cavity 101 between the second half-shell 120 and the first half-shell 110. The cable 300 may include a first end 320 and a second end 330. The first end 320 is connected to a first end of the winding segment 310 and is located in the receiving cavity 101; the second end 330 is connected to a second end of the winding segment 310 and is located outside the housing 100 through the opening 102. Here, the winding segment 310, the first end 320, and the second end 330 may be different parts of the same wire.

[0071] In this embodiment, the manner in which the positioning component 500 is movably disposed on the housing 100 is not limited. For example, the positioning component 500 may be rotatably disposed on the housing 100 via a pivot structure. Alternatively, the positioning component 500 may be translatably disposed on the housing 100 via a slide rail, slide groove, or the like.

[0072] In this embodiment, the damping component 400 can be movably disposed on the housing 100 or fixed to the housing 100. The damping component 400 is used to cooperate with the functional component 600 to provide rotational damping force to the winding component 200.

[0073] Here, the damping component 400 can provide a bidirectional rotational damping force to the winding member 200, or a unidirectional rotational damping force to the winding member 200.

[0074] In this embodiment, the functional component 600 can be disposed on the end side of the winding component 200 by means of bonding, snap-fitting, welding, etc.

[0075] The structure of the functional component 600 is not limited, as long as the functional component 600 can cooperate with both the positioning component 500 and the damping component 400.

[0076] For example, the functional component 600 may have at least one groove 621; the at least one groove 621 may be used only to mate with the positioning component 500, or only to mate with the damping component 400, or it may be used to mate with both the positioning component 500 and the damping component 400.

[0077] In this example, the number of at least one groove 621 is not limited. For example, the functional component 600 may have at least two grooves 621. The location of the grooves 621 is not limited. For example, the grooves 621 may be located on the periphery of the functional component 600 or on the end face side of the functional component 600.

[0078] As an example, the positioning component 500 has a first position that engages with at least one groove 621 and a second position that is separated from at least one groove 621. When the positioning component 500 is in the first position that engages with at least one groove 621, the winding member 200 cannot rotate relative to the housing 100 because the positioning component 500 is engaged with the functional member 600. This fixes the position of the winding member 200 relative to the housing 100 through the functional member 600, so that when the operator needs to fix the position of the winding member 200 relative to the housing 100, the positioning component 500 can be placed in the first position. When the operator needs to rotate the winding member 200 relative to the housing 100, the positioning component 500 can be placed in the second position. In the second position, the positioning component 500 is separated from at least one groove 621, and the positioning component 500 does not affect the rotation of the winding member 200.

[0079] Here, the positioning component 500 can be a strip-shaped structure. The positioning component 500 can move relative to the housing 100 via a moving mechanism or a rotating mechanism. When the positioning component 500 moves to the first position, a portion of the positioning component 500 can be located within at least one groove 621 to engage with the functional component 600. When the positioning component 500 moves to the second position, a portion of the positioning component 500 is located outside at least one groove 621 to separate from the functional component 600, thus not affecting the rotation of the winding component 200. The positioning component 500 can be driven by the driving force of a drive mechanism such as a motor or telescopic cylinder, or it can be moved under the external force of the operator.

[0080] Of course, the positioning component 500 may not engage with at least one groove 621, or the positioning component 500 may engage directly with the surface of the functional component 600 to fix the position of the winding component 200 relative to the housing 100 by means of the friction between the surfaces of the positioning component 500 and the functional component 600.

[0081] As another example, the positioning component 500 has a first position where it engages with the surface of the functional component 600, where the friction between the positioning component 500 and the surface of the functional component 600 is greater than the rotational force of the winding component 200. The positioning component 500 also has a second position where it is separated from the surface of the functional component 600, where there is no friction between the positioning component 500 and the surface of the functional component 600, and the winding component 200 can rotate freely relative to the housing 100.

[0082] Here, the positioning component 500 can switch between the first position and the second position by rotating or translating.

[0083] As yet another example, the damping component 400 is used to engage with at least one groove 621 to provide a damping force for the rotation of the winding member 200.

[0084] Here, the damping assembly 400 is rotatably disposed on the housing 100. The damping assembly 400 may include at least one protrusion that engages with at least one groove 621 to provide a damping force for the rotation of the winding member 200 through the engagement of the at least one protrusion with the at least one groove 621. In one application, the functional member 600 is a gear structure; the damping assembly 400 may include a damping gear 410, thereby providing a damping force for the rotation of the winding member 200 through gear meshing.

[0085] Of course, the damping component 400 may not necessarily mate with at least one groove 621; the damping component 400 may also directly mate with the surface of the functional component 600 to provide rotational damping force to the winding component 200 through the friction between the surfaces of the damping component 400 and the functional component 600. Here, the damping component 400 may be fixed to the housing 100.

[0086] The friction between the surfaces of the damping component 400 and the functional component 600 is less than the rotational force of the winding component 200. The friction between the surfaces of the damping component 400 and the functional component 600 is only used to reduce the rotational speed of the winding component 200 to prevent the winding component 200 from rotating too fast and injuring the operator.

[0087] As another example, the damping assembly 400 is used to mate with the end face of the functional member 600 to provide a rotational damping force to the winding member 200 through the friction between the end faces of the damping assembly 400 and the functional member 600. Alternatively, the damping assembly 400 can also be used to mate with the peripheral surface of the functional member 600 to provide a rotational damping force to the winding member 200 through the friction between the damping assembly 400 and the peripheral surface of the functional member 600.

[0088] In some optional implementations of this application, the functional component 600 has at least one groove 621 on its periphery; the positioning component 500 may include a connector 510. The connector 510 is rotatably disposed on the housing 100; the connector 510 has a first protrusion 511 that engages with at least one groove 621; the first protrusion 511 has a first position that engages with at least one groove 621 and a second position that is separated from at least one groove 621; when the connector 510 rotates to the first position where the first protrusion 511 engages with at least one groove 621, the winding component 200 is fixed relative to the housing 100 by the position of the functional component 600; thus, the connector 510 can prevent the winding component 200 from rotating; when the connector 510 rotates to the second position where the first protrusion 511 is separated from at least one groove 621, the winding component 200 can rotate relative to the housing 100.

[0089] In this implementation, the number of at least one groove 621 is not limited. For example, the number of grooves 621 is at least two, and at least two grooves 621 are spaced apart along the periphery of the functional member 600. Here, the number of grooves 621 can be greater than or equal to 3, 4, 5, 10, or 20. When the number of grooves 621 is set to be larger, the positioning of the winding member 200 relative to the housing 100 can be more accurate and precise. When the number of grooves 621 is greater than or equal to 5, the rotation of the winding member 200 relative to the housing 100 can stop within an accuracy range of less than 90 degrees, thereby greatly improving the positioning accuracy of the winding member 200 relative to the housing 100. As an example, such as Figure 1 and Figure 2 As shown, the number of grooves 621 is equal to 21. Here, the winding member 200 can rotate relative to the housing 100 and stop at each position of approximately 17 degrees, thereby greatly improving the positioning accuracy of the winding member 200 relative to the housing 100.

[0090] In this implementation, the connector 510 is rotatably mounted on the housing 100 via a rotating shaft structure. The manner in which the connector 510 is in the first and second positions is not limited. For example, the connector 510 can be driven to rotate to the first or second position by the driving force of a drive mechanism such as a motor or telescopic cylinder, or it can be rotated to the second position by external force from the operator.

[0091] As an example, such as Figure 1 and Figure 2As shown, the positioning assembly 500 may further include a limiting gear 520 and a resetting member 530. The end of the connector 510 facing the winding member 200 also has two spaced-apart second protrusions 512 and third protrusions 513; the limiting gear 520 is rotatably connected to the housing 100 and located between the second protrusions 512 and the third protrusions 513; the limiting gear 520 is used to engage with either the second protrusion 512 or the third protrusion 513 to limit the swing position of the connector 510; the resetting member 530 is connected to the housing 100; the resetting member 530 is used to provide a restoring force to the connector 510 during swing.

[0092] Here, the limiting gear 520 may include: a first side surface, a first tooth groove, and a second tooth groove. The first tooth groove and the second tooth groove are used to engage with the third protrusion 513; the first side surface is used to engage with the second side surface of the second protrusion 512; wherein, the depth of the first tooth groove is greater than the depth of the second tooth groove, and the distance between the first tooth groove and the axis of the limiting gear 520 is less than the distance between the second tooth groove and the axis of the limiting gear 520; in the stretched state, the first side surface and the second side surface are arranged adjacent to each other, and the connecting member 510 is in the second position; in the positioned state, the third protrusion 513 is located in the second tooth groove, and the connecting member 510 is in the first position; in the retracted state, the third protrusion 513 is located in the first tooth groove, and the connecting member 510 is in the second position.

[0093] Here, the structure of the reset member 530 is not fixed. For example, the reset member 530 can be a spring-loaded structure, so that the connecting member 510 can be in a position that engages with the limit gear 520.

[0094] During use, in the stretched state, an external force overcomes the deformation force of the elastic element 710 to pull the cable 300. The cable 300 drives the winding element 200 to rotate in the stretching direction, and the length of the cable 300 increases. At this time, the first protrusion 511 is outside the groove 621. When the cable 300 is pulled to a suitable length, the external force is removed, and the winding element 200 rotates in the retracting direction under the deformation force of the elastic element 710. When the winding element 200 rotates to the side where the groove 621 faces the connector 510, the reset element 530 provides a force to the connector 510 to rotate in the first direction, causing... The first protrusion 511 is located within the groove 621. Simultaneously, in the stretched state, due to the adjacent arrangement of the first and second sides, the connector 510 also pushes the limiting gear 520 to rotate. When the connector 510 rotates until the third protrusion 513 is located within the second tooth groove, the limiting gear 520 prevents the connector 510 from rotating. Since the first protrusion 511 is located within the groove 621, the resistance of the first protrusion 511 to the winding member 200 is greater than the force provided by the elastic member 710 for the winding member 200 to rotate in the receiving direction, thus causing the connector 510 to be in a position where the first protrusion 511 is located within the groove 621. The positioning state within the groove 621 ensures that the cable 300 is stably at the appropriate length. When it is necessary to store the cable 300 inside the housing 100, the cable 300 can be pulled again by external force. The cable 300 drives the winding member 200 to rotate in the stretching direction, thereby causing the first protrusion 511 to disengage from the groove 621. At the same time, since the third protrusion 513 is located in the second tooth groove, the connector 510 will push the limiting gear 520 to rotate until the third protrusion 513 corresponds to the first tooth groove. When the external force is removed, the first protrusion 511 will be located in the groove 621 again, and the winding member 200 will be pulled out. The wire component 200 will drive the connector 510 to rotate a certain angle in the first direction through the first protrusion 511. When the connector 510 rotates to the point where the third protrusion 513 is located in the first tooth groove, since the depth of the first tooth groove is greater than the depth of the second tooth groove, the first protrusion 511 is located outside the groove 621. At this time, the connector 510 cannot prevent the winding component 200 from rotating through the first protrusion 511. Under the action of the elastic member 710, the winding component 200 rotates continuously in the storage direction until the part of the cable 300 that can be coiled outside the winding component 200 is completely coiled outside the winding component 200.When the length of cable 300 needs to be adjusted, the cable 300 can be pulled by external force to overcome the deformation force of elastic element 710. Cable 300 drives winding element 200 to rotate in the stretching direction. When winding element 200 rotates to the point where groove 621 faces connector 510, first protrusion 511 enters groove 621. Winding element 200 can drive connector 510 to rotate in the second direction through first protrusion 511. At the same time, since third protrusion 513 is located in first tooth groove, connector 510 can push limit gear 520 to rotate at a certain angle. When winding element 200 drives connector 510 to rotate in the second direction through first protrusion 511 until first protrusion 511 is outside groove 621, data cable storage device is in the stretched state again. At this time, first side and second side are arranged adjacent to each other. The data cable storage device can repeat the above process during use, switching between stretched state, positioning state and storage state in sequence to facilitate use of data cable storage device. Here, the first direction and the second direction are opposite, and the storage direction and the stretching direction are opposite.

[0095] In this implementation, the structure of functional component 600 is not limited.

[0096] For example, such as Figure 1 and Figure 2 As shown, the peripheral side of the functional component 600 is a first toothed portion, and the functional component 600 is a gear structure; the damping assembly 400 may include: a damping gear 410, which is rotatably disposed in the housing 100 and meshes with the first toothed portion.

[0097] In this example, the first protrusion 511 has a first position that engages with at least one groove 621 of the first tooth, and a second position that is separated from at least one groove 621 of the first tooth. Here, at least one groove 621 is a tooth groove of the first tooth.

[0098] Here, the positions of the damping gear 410 and the connecting member 510 are not limited, as long as the damping gear 410 and the connecting member 510 respectively mate with different tooth grooves of the first tooth. For example, as Figure 1 and Figure 2 As shown, the damping gear 410 and the connecting piece 510 can be located on opposite sides of the functional component 600 so that the functional component 600 is subjected to more uniform force in the circumferential direction, thereby making the rotation of the functional component 600 smoother.

[0099] In this example, the damping assembly 400 may further include: a base 420, which can be fixed to the housing 100 by means of bonding, snap-fitting, etc.; a damping gear 410 is rotatably disposed on the base 420 by means of a rotating shaft structure, etc., and there is a damping force between the damping gear 410 and the base 420; when the damping gear 410 rotates relative to the base 420, the damping force between the damping gear 410 and the base 420 can reduce the rotation speed of the damping gear 410, thereby reducing the rotation speed of the winding member 200 through the damping gear 410.

[0100] Here, the friction between the damping gear 410 and the base 420 provides the damping force for the rotation of the damping gear 410. Of course, other damping structural components can also be installed inside the base 420, which can provide damping force for the damping gear 410.

[0101] In this example, the damping gear 410 and the base 420 can provide a unidirectional damping force to the winding member 200 in the direction of cable reception 300 rotation, thereby reducing the rotation speed of the winding member 200 in the direction of cable reception 300 and preventing the winding member 200 from rotating too fast and injuring the operator. At the same time, the damping gear 410 does not affect the rotation speed of the winding member 200 in the direction of cable unfolding 300, thereby increasing the unfolding speed of the winding member 200 of the data cable device.

[0102] Here, the method by which the damping gear 410 and the base 420 provide unidirectional damping force is not limited. The method by which the damping gear 410 and the base 420 provide unidirectional damping force is similar to the working principle of a unidirectional damping gear, and will not be described in detail here.

[0103] Of course, the damping gear 410 and the base 420 can also provide bidirectional rotational damping force to the winding member 200.

[0104] In some optional implementations of the embodiments of this application, such as Figure 1 and Figure 2 As shown, the winding member 200 has a mounting groove 202 on its first end side; the functional member 600 may include a mounting portion 610 and a functional portion 620. The mounting portion 610 is disposed within the mounting groove 202; the functional portion 620 protrudes axially from the mounting groove 202; the positioning component 500 has a first position that engages with the functional portion 620 and a second position that is separate from the functional portion 620; the damping component 400 is used to engage with the functional portion 620. By separating the functional member 600 from the winding member 200, the functional member 600 can be manufactured separately, thereby reducing the manufacturing difficulty of the data cable device.

[0105] Of course, in other implementations, the winding component 200 and the functional component 600 can also be different parts of a single structural component.

[0106] In this implementation, the functional part 620 and the winding member 200 can be coaxially arranged; the outer peripheral side of the functional part 620 has at least one groove 621; the positioning component 500 has a first position that engages with at least one groove 621 and a second position that is separated from at least one groove 621.

[0107] Of course, the functional part 620 may not have the groove 621 provided, and the positioning component 500 and the functional part 620 may have direct surface contact.

[0108] Here, the functional part 620 is similar to the functional component 600 mentioned above, and will not be described again here.

[0109] In this implementation, such as Figure 5 As shown, the winding member 200 may include: a cylindrical portion 210, an annular plate portion 220, and a plate portion 230. The annular plate portion 220 is connected to the first end of the cylindrical portion 210; the cylindrical portion 210 and the annular plate portion 220 define a mounting groove 202; the plate portion 230 is connected to the second end of the cylindrical portion 210; the winding section 310 is used to wind around the cylindrical portion 210 and is located within the space defined by the annular plate portion 220 and the plate portion 230; the data cable device may further include: an elastic member 710, which is disposed in the cavity defined by the cylindrical portion 210 through the mounting groove 202; the elastic member 710 is connected to the housing 100 and the winding member 200 respectively to provide the winding member 200 with a restoring force for rotation in the direction of receiving the cable 300; by disposing of the functional member 600 at the mounting groove 202, the elastic member 710 can be shielded to prevent it from coming out of the cavity defined by the cylindrical portion 210; and the placement space of the functional member 600 can be reduced, thereby achieving miniaturization of the data cable device.

[0110] The structure of the elastic element is not limited. For example, in some embodiments, the elastic element 710 may be a coil spring.

[0111] The method by which the elastic element 710 is connected to the winding member 200 and the housing 100 is not limited. For example, in some embodiments, the first end of the elastic element 710 can be fixed to the winding member 200 by snap-fitting, bonding, welding, etc., and the second end of the elastic element 710 can be fixed to the housing 100 by snap-fitting, bonding, welding, etc. As an example, the second end of the elastic element 710 is fixed to the housing 100 by snapping it onto the connecting post 121.

[0112] In this implementation, such as Figure 5As shown, the data cable device may further include: a circuit board 720 and an interface component 730. The circuit board 720 is disposed at the end of the plate-shaped portion 230 away from the cylindrical portion 210 by means of adhesive bonding, snap-fit, etc., and is electrically connected to the first end 320 of the cable 300; the second end 330 of the cable 300 is located outside the housing 100 through the opening 102; the interface component 730 is electrically connected to the circuit board 720; the interface portion 731 of the interface component 730 is exposed through the slot 103 of the housing 100, such as... Figure 4 As shown.

[0113] The method of electrically connecting the interface component 730 and the circuit board 720 is not limited. For example, one of the interface component 730 and the circuit board 720 is provided with at least one annular groove, and the other of the interface component 730 and the circuit board 720 is provided with a conductive protrusion inserted into the annular groove, and a conductive part electrically connected to the conductive protrusion is provided in the annular groove. When the winding component 200 rotates relative to the housing 100, the conductive protrusion slides in the annular groove and is electrically connected to the conductive part.

[0114] The interface portion 731 is a conductive structure. The interface portion 731 can be electrically connected to either a power supply device or a user device. The second end 330 of the cable 300 can also be electrically connected to either a power supply device or a user device.

[0115] When the winding member 200 rotates relative to the housing 100, the cable 300 extends out of the housing 100 or retracts into the housing 100 through the opening 102 to adjust the distance between the second end 330 of the cable 300 and the interface portion 731.

For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this utility model will not be described separately.

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
