AI Technical Summary
In existing wire winding devices, the winding speed driven by springs is unstable in the early stages of winding, which can easily cause a whipping effect. Furthermore, after long-term use, the elasticity of the springs decreases, making it impossible to return to its normal position, which affects the product experience.
The system employs a damping structure, including damping coordination between the first and second parts. The first part is driven to rotate via a drive shaft, and the damping force drives the winding reel to rotate synchronously, thereby achieving automatic winding and smooth take-up of the wire.
By leveraging the flexible transmission characteristics of the winding reel through damping force, instantaneous torque fluctuations of the drive shaft are buffered, preventing excessive tension of the wire, improving the smoothness and reliability of winding, preventing wire damage, and extending the service life of the device.

Abstract
Description
Technical Field
[0001] This application relates to the field of data cable winding technology, and in particular to a cable winding device, a data cable device, and a charging device. Background Technology
[0002] In related technologies, cable winding devices are designed using springs as the power source. When the data cable is pulled out, it drives the reel of the winding device to rotate, simultaneously compressing the spring and storing elastic energy. When it's time to rewind, the spring's elastic energy is released, causing the reel to reverse and rewind the data cable. However, in this spring-driven winding method, the spring's elastic energy is at its maximum at the beginning of winding, resulting in a fast and unstable winding speed, which can easily create a whiplash effect, causing the cable to strike the user during winding. Furthermore, after long-term use, the spring's elasticity decreases due to material fatigue from repeated pulling and winding of the data cable, leading to insufficient elasticity or even failure to properly reset the data cable, affecting the user experience.

[0033] Based on the wire winding device of this application embodiment, on the one hand, when the power component is activated and the drive shaft rotates, the first part of the damping structure rotates synchronously with the drive shaft. The damping force generated by the damping cooperation between the first and second parts can drive the second part to drive the winding reel to rotate synchronously, realizing automatic winding of the wire. By driving the second part to drive the winding reel to rotate synchronously through the damping force, the flexible transmission characteristic of the damping force can buffer the instantaneous torque fluctuation of the drive shaft, so that the winding speed of the winding reel is smoothly matched with the rotation speed of the drive shaft. This avoids the problem of excessive tension of the wire caused by sudden changes in the rotation speed of the drive shaft in traditional rigid connections, and improves the stability and reliability of the wire winding device.
[0034] On the other hand, when the user pulls the cable, the reel rotates under the traction force of the cable. At this time, the drive shaft generates resistance due to the power component being shut down, causing the relative speed difference between the first and second parts of the damping structure to exceed the synchronization range that the damping force can maintain. At this point, the second part rotates relative to the first part, indicating that the reel can rotate freely relative to the drive shaft, preventing the reel from jamming during pulling. Simultaneously, the damping structure still applies a certain resistance to the second part through damping force, which prevents damage to the cable due to excessively rapid pulling.

[0052] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0053] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0056] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0057] This application discloses a charging device, including a data cable assembly and a charging head. The data cable assembly includes a data cable and a cable winding device. Both ends of the data cable have connectors, and the charging head has an interface adapted to one of these connectors. Exemplarily, the charging head can be a power adapter or a charger. The charging head is used to connect to a power outlet. When one connector of the data cable is plugged into the interface of the charging head, the other connector of the data cable can be used to connect to electronic devices such as mobile phones, headphones, or computers, thereby charging the electronic devices.
[0058] Please see Figure 1 and Figure 2This application proposes a data cable device 10, including a data cable 11 and a cable winding device 20, with the data cable 11 wound around the cable winding device 20. When a user needs to use the data cable 11, they can pull the data cable 11 to detach part or all of it from the cable winding device 20; after use, the cable winding device 20 can rewind the data cable 11. In other words, by setting up the cable winding device 20, convenient storage of the data cable 11 is achieved without affecting its normal use, avoiding tangling and knotting.
[0059] In related technologies, cable winding devices primarily utilize springs for power. When the data cable is pulled out, it drives the reel of the winding device to rotate, simultaneously compressing the spring and storing elastic energy. When winding is needed, this elastic energy is released, causing the reel to reverse and wind up the data cable. However, in this spring-driven winding method, the spring's elastic energy is at its maximum at the beginning of winding, resulting in a fast and unstable winding speed, which can easily cause a whiplash effect, potentially injuring the user during winding. Furthermore, with prolonged use, the spring's elasticity decreases due to material fatigue from repeated pulling and winding of the data cable, leading to insufficient elasticity or even the inability to properly reset the data cable, impacting the user experience.
[0060] Please see Figure 2 and Figure 3 This application also proposes a wire winding device 20. The wire winding device 20 includes a winding spool 100, a drive assembly 200, and a damping structure 300; the winding spool 100 is used to wind the wire 12, the drive assembly 200 includes a power component with a drive shaft 211; the damping structure 300 includes a first part 310 and a second part 320 that can rotate relative to each other, the first part 310 and the second part 320 forming a damping fit, the first part 310 being connected to the drive shaft 211, and the second part 320 being connected to the winding spool 100; wherein, when the drive shaft 211 drives the first part 310 to rotate, the first part 310 drives the second part 320 to rotate together with the winding spool 100 through damping force; when the winding spool 100 rotates due to pulling the wire 12, the winding spool 100 drives the second part 320 to rotate relative to the first part 310.
[0061] On the one hand, when the power component 210 is activated, causing the drive shaft 211 to rotate, the first part 310 of the damping structure 300 rotates synchronously with the drive shaft 211. The damping force generated by the damping cooperation between the first part 310 and the second part 320 can drive the second part 320 to drive the winding reel 100 to rotate synchronously, realizing the automatic winding and coiling of the wire 12. By driving the second part 320 to rotate synchronously with the winding reel 100 through the damping force, the flexible transmission characteristics of the damping force can buffer the instantaneous torque fluctuations of the drive shaft 211, so that the winding speed of the winding reel 100 and the rotation speed of the drive shaft 211 are smoothly matched. This avoids the problem of excessive tension of the wire 12 caused by sudden changes in the rotation speed of the drive shaft 211 in traditional rigid connections, and improves the stability and reliability of the wire winding device 20 in winding the wire 12.
[0062] On the other hand, when the user pulls the cable 12, the reel 100 rotates under the traction force of the cable 12. At this time, the drive shaft 211 generates resistance due to the power component 210 being closed, causing the relative speed difference between the first part 310 and the second part 320 of the damping structure 300 to exceed the synchronization range that the damping force can maintain. At this time, the second part 320 rotates relative to the first part 310, indicating that the reel 100 can rotate freely relative to the drive shaft 211, avoiding the cable reel 100 from getting stuck during pulling. At the same time, the damping structure 300 still applies a certain resistance to the second part 320 through the damping force, which can prevent the cable 12 from being damaged due to pulling too fast.
[0063] It is understandable that when the wire winding device 20 winds up the wire 12, friction exists between the wire 12 and the reel 100, as well as between the wire 12 itself when it is wound in multiple layers. The sum of these frictional forces can be considered as the resistance to the rotation of the reel 100. The damping force generated by the damping cooperation between the first part 310 and the second part 320 must be greater than this total frictional force in order to drive the second part 320 to rotate together with the reel 100. Furthermore, when the reel 100 is subjected to external resistance, and the damping force between the first part 310 and the second part 320 is less than this external resistance, the damping force cannot drive the second part 320 to rotate. The first part 310 rotates relative to the second part 320 under the drive of the drive shaft 211, that is, the drive shaft 211 drives the first part 310 to idle, avoiding the drive shaft 211 from jamming and causing damage to the power component 210.
[0064] When the cable 12 is pulled, the reel 100 rotates under the influence of the cable 12, simultaneously causing the second part 320 to rotate. The first part 310 experiences a damping force due to the rotation of the second part 320, and under the drive of this damping force, the first part 310 tends to rotate. Because the power component 210 is in the closed state at this time, the drive shaft 211 is hindered from rotating by the resistance of the internal structure of the power component 210, which in turn hinders the rotation of the first part 310. Therefore, the rotation of the second part 320 relative to the first part 310 has two scenarios: when the damping force is greater than the resistance, the first part 310 and the second part 320 rotate in the same direction at a different speed; when the damping force is less than the resistance, the first part 310 remains stationary. Optionally, in some embodiments, when the reel 100 rotates due to the pulling of the cable 12, the damping force on the first part 310 is less than the resistance on the drive shaft 211, to prevent the drive shaft 211 from rotating when the power component 210 is closed, which could damage the internal structure of the power component 210.
[0065] Correspondingly, if the drive component 200 shuts down midway during the winding process of the wire winding device 20 on the wire 12, the reel 100 stops rotating, and the wire 12 also stops winding, and if the reel 100 is subjected to external force at this time, it needs to overcome the damping force of the second part 320 in order for the reel 100 to rotate. This ensures that, under normal conditions, the wire 12 already wound on the reel 100 will not detach from the reel 100 due to the reverse rotation of the reel 100. Similarly, if the pulling action is suddenly stopped during the process of pulling the wire 12 to rotate the reel 100, the wire 12 that has detached from the reel 100 will not rewrap onto the reel 100 due to the reverse rotation of the reel 100. That is, the reel 100 can stop freely at any position, realizing the control of the winding length or detachment length of the wire 12.
[0066] It should be noted that the wire 12 includes, but is not limited to, linear components such as data cable 11, yarn, cable, and flexible tubing. For example, the wire 12 in the data cable device 10 is the data cable 11, with a connector 13 at its end. The data cable 11 serves as a structural component in the data cable device 10 for power or signal transmission, and is wound on a reel 100. The specific model of the data cable 11 is not limited here; designers can choose appropriately according to actual needs. The connector 13 of the data cable 11 can be used to connect to external devices, including but not limited to mobile phones or chargers. It should be noted that the number of connectors 13 on the data cable 11 can be one or more; when the number of connectors 13 on the data cable 11 is one, the type of the one connector 13 includes, but is not limited to, one of USB connectors, type-C connectors and type-A connectors; when the number of connectors 13 on the data cable 11 is multiple, the types of the multiple connectors 13 can be the same or different, and the types of the multiple connectors 13 include, but are not limited to, one or more of USB connectors, type-C connectors and type-A connectors.
[0067] Specifically, the damping structure 300 can be a friction damper or an electromagnetic damper. It is understood that the friction damper or electromagnetic damper has a separated state and a engaged state. When the drive shaft 211 rotates actively, the friction damper is in the engaged state, and the first part 310 and the second part 320 are tightly fitted together under pressure; or the electromagnetic damper is in the engaged state, and the first part 310 and the second part 320 are attracted by electromagnetic force. At this time, the friction between the first part 310 and the second part 320 is large enough to overcome the resistance of the reel 100 winding the wire 12, ensuring that the torque of the drive shaft 211 can be effectively transmitted to the second part 320, thereby driving the reel 100 to rotate synchronously to complete the winding of the wire 12. When the wound wire 12 is large or the number of winding layers of the wire 12 is large, resulting in a large resistance to winding the wire 12, the friction between the first part 310 and the second part 320 in the mating state can be increased by increasing the contact area between the first part 310 and the second part 320, increasing the clamping force between the first part 310 and the second part 320, or using a material with a high coefficient of friction to make the first part 310 and the second part 320, so as to ensure the stability of the winding function of the wire winding device 20.
[0068] When the user pulls the cable 12, causing the reel 100 to rotate in the opposite direction, the first part 310 and the second part 320 of the friction damper separate due to the release of pressure. The second part 320 rotates with the reel 100, while the first part 310 and the drive shaft 211 remain stationary. Furthermore, when the first part 310 and the second part 320 are separated, the rotational resistance between the reel 100 and the drive shaft 211 is significantly reduced, making the pulling operation easier for the user. Similarly, if an electromagnetic damper is used, the first part 310 and the second part 320 can be separated by power-off control to reduce pulling resistance.
[0069] Please see Figures 3 to 5 In some embodiments, the damping structure 300 is a rotary damper. The second part 320 has a receiving cavity 3211, a through hole 3212 communicating with the receiving cavity 3211, and a damping medium 322 disposed in the receiving cavity 3211; the first part 310 passes through the through hole 3212 to cooperate with the second part 320 to form the damping structure 300.
[0070] Specifically, the second part 320 includes a damping box 321 connected to the reel 100. The damping box 321 has a receiving cavity 3211 and a through hole 3212 communicating with the receiving cavity 3211. A transmission part 3213 is provided on the inner wall of the receiving cavity 3211 opposite to the through hole 3212. A damping medium 322 is disposed in the receiving cavity 3211. The damping medium 322 is used to provide damping force when the first part 310 and / or the second part 320 rotates. The second part 320 includes a rotating shaft 311, which passes through the through hole 3212. One end of the rotating shaft 311 is placed in the receiving cavity 3211 and cooperates with the transmission part 3213. The other end is connected to the drive shaft 211.
[0071] By filling and encapsulating the damping medium 322 within the receiving cavity 3211 of the damping box 321, external dust, moisture, and other impurities can be effectively isolated. When the drive shaft 211 drives the rotating shaft 311 to rotate, the damping medium 322 is agitated or sheared within the receiving cavity 3211 by the rotating shaft 311 and the transmission part 3213, generating a continuous and uniform damping force. Existing open damping structures 300, including exposed friction plates, are prone to damping force attenuation due to contamination of the damping medium 322. This solution, through the sealed design of the receiving cavity 3211, ensures the long-term stability of the performance of the damping medium 322, especially in harsh environments such as dusty and humid conditions, maintaining the reliable damping force provided by the damping structure 300.
[0072] The mating connection between the rotating shaft 311 and the transmission part 3213 is located within the receiving cavity 3211 and is filled and encased by the damping medium 322, which increases the effective area and disturbance intensity of the damping medium 322. When the drive shaft 211 rotates actively, the rotating shaft 311 rotates with the drive shaft 211, forming relative motion with the transmission part 3213 on the inner wall of the damping box 321. This forces the damping medium 322 to be squeezed and sheared, thereby efficiently transmitting the torque of the drive shaft 211 to the damping box 321, ultimately driving the winding reel 100 to synchronously wind up the wire 12. Compared with the traditional damping structure 300 with single-plane friction, the transmission efficiency of the damping force in the damping structure 300 is improved by increasing the effective area and disturbance intensity of the damping medium 322.
[0073] It should be noted that the damping medium 322 includes, but is not limited to, damping oil, damping grease, magnetic fluid, or elastic colloid. For example, the type and filling amount of the damping medium 322 can be adjusted according to actual needs. If a larger damping force is required, high-viscosity silicone oil or magnetic fluid can be used to enhance damping through an external magnetic field; if a smaller damping force is required, low-viscosity silicone oil or elastic colloid can be used. Optionally, the damping medium 322 fills the receiving cavity 3211 to ensure the damping effect provided by the damping medium 322 to the damping box 321 and the second part 320.
[0074] Specifically, in some embodiments, the damping box 321 includes a base 3214 and a top cover 3215. The base 3214 is connected to the top cover 3215 to form a receiving cavity 3211. The top cover 3215 is provided with a through hole 3212. A transmission part 3213 is provided on the inner wall of the base 3214 opposite to the through hole 3212.
[0075] Optionally, the base 3214 is provided with a receiving groove, and the upper cover 3215 is designed as a plate and is placed on the receiving groove to form a receiving cavity 3211. The bottom wall of the receiving groove opposite to the through hole 3212 is provided with a transmission part 3213.
[0076] Specifically, in some embodiments, the transmission part 3111 is a docking groove 3111a, and one end of the rotating shaft 311 is inserted into the docking groove 3111a. The transmission part 3111 can also be a shaft 3213a, with one end of the rotating shaft 311 having a docking groove 3111a, and the shaft 3213a being inserted into the docking groove 3111a.
[0077] The separate structures of the base 3214 and the top cover 3215 can be processed independently. The receiving groove of the base 3214 can be quickly formed by processes such as stamping, injection molding, or CNC milling. The mating groove 3111a or the protruding shaft 3213a at the bottom of the groove can be processed simultaneously when the base 3214 is formed. For example, the corresponding structure can be directly designed in the injection mold, realizing the integral forming of the base 3214 and the transmission part 3213. The through hole 3212 of the top cover 3215 can be achieved by drilling or pre-reserving holes in the mold, ensuring a more precise fit between the rotating shaft 311 and the transmission part 3213 after it passes through, and improving the disturbance efficiency of the damping medium 322. Correspondingly, the top cover 3215 can also be provided with a receiving groove, the base 3214 can be designed as a plate and cover the receiving groove to form a receiving cavity 3211, and the transmission part 3213 is provided on the side of the base 3214 opposite to the through hole 3212. The base 3214 and the top cover 3215 may also be provided with receiving slots, and the base 3214 and the top cover 3215 are connected to make the two receiving slots communicate.
[0078] The base 3214 and the top cover 3215 are designed to be detachably connected. When the damping force of the damping medium 322 decreases due to aging, contamination, or evaporation, only the top cover 3215 needs to be removed to directly access the damping medium 322 in the receiving groove, and to clean, replace, or replenish the damping medium 322. If the transmission part 3213 or the rotating shaft 311 needs to be repaired due to long-term wear, the base 3214 or the rotating shaft 311 can be replaced separately, without the need to scrap the entire damping structure 300. For example, the top cover 3215 and the base 3214 can be connected by bolts or by clips.
[0079] Furthermore, the outer peripheral edge of the base 3214 facing the upper cover 3215 is provided with a flange, and the upper cover 3215 is provided with a corresponding groove, which can enhance the structural strength of the connection between the base 3214 and the upper cover 3215 and the sealing performance at the connection interface. A sealing ring can be provided at the connection between the base 3214 and the upper cover 3215, for example, a sealing groove is opened on the contact surface between the base 3214 and the upper cover 3215, and the sealing ring is placed in the sealing groove. At the same time, a seal can be provided at the through hole 3212, which allows the rotating shaft 311 to rotate freely in the through hole 3212, while preventing the damping medium 322 from leaking. This further improves the sealing performance of the receiving cavity 3211, prevents external dust and moisture from entering and contaminating the damping medium 322, and ensures the long-term stability of the performance of the damping medium 322.
[0080] Please see Figure 2 , Figure 7 , Figure 8 and Figure 9In some embodiments, the reel 100 includes a winding frame 110 and two supports 120. The winding frame 110 is connected to the damping structure 300; the two supports 120 are connected to the winding frame 110 and are spaced apart axially on the winding frame 110. The two supports 120 and the winding frame 110 constitute an annular receiving groove 130 for receiving the wire 12. The winding frame 110 includes a central portion 111 and an extension portion 112. The extension portion 112 is disposed on the outer peripheral wall of the central portion 111 and extends circumferentially along the central portion 111. The extension portion 112 and the central portion 111 constitute a clamping groove 113 for receiving the end of the wire 12. The clamping groove 113 communicates with the annular receiving groove 130.
[0081] The winding frame 110 and the two supports 120 are axially spaced to form an annular receiving groove 130. Exemplarily, the winding frame 110 is cylindrical, and the two supports 120 are disc-shaped with a diameter larger than the winding frame 110. The spacing between the two supports 120 matches the diameter of the wire 12, providing a clear winding path for the wire 12. When the wire 12 is spirally wound along the outer periphery of the winding frame 110, the limiting effect of the supports 120 on both sides prevents the wire 12 from deviating from the predetermined track due to radial offset during pulling or winding. The constraint of the annular receiving groove 130 allows the wire 12 to be arranged tightly layer by layer, reducing crossover and significantly lowering the probability of tangling and knotting.
[0082] The clamping groove 113 formed by the central portion 111 and the extension portion 112 of the winding frame 110 is, exemplarily, a cylindrical central portion 111 and a circumferentially extending rib. The rib and the outer wall of the central portion 111 form a gap slightly smaller than the diameter of the wire 12. This gap can serve as a clamp to effectively hold and fix the beginning or end of the wire 12. The wire 12 can be completely detached from the wire winding device 20. When winding begins, the user can insert the end of the wire 12 into the clamping groove 113. The narrow slit design of the clamping groove 113 fixes the end of the wire 12, preventing the end from loosening due to changes in the tension of the wire 12 during winding. The communication design between the clamping groove 113 and the annular storage groove 130 ensures that after the end of the wire 12 is fixed, the main body of the wire 12 can smoothly transition into the annular storage groove 130.
[0083] Please see Figure 4 and Figure 7 In some embodiments, the outer periphery of the second part 320 is provided with a plurality of lugs 3216, one of the lugs 3216 and the winding reel 100 is provided with a fixing post 1111, and the other is provided with a fixing hole 3216a, with the fixing post 1111 inserted into the fixing hole 3216a.
[0084] The lug 3216 engages with the center portion 111 of the winding frame 110 via a fixing post 1111 and a fixing hole 3216a, enabling rapid radial and circumferential positioning during assembly. After the fixing post 1111 is inserted into the fixing hole 3216a, it restricts the radial offset of the second portion 320 relative to the winding frame 110, ensuring that their central axes are highly aligned. Furthermore, the number of lugs 3216 is multiple, and correspondingly, the number of fixing posts 1111 and fixing holes 3216a is also multiple. The multiple engaging fixing posts 1111 and fixing holes 3216a provide circumferential restraint, preventing rotational offset of the second portion 320 and achieving synchronous rotation between the second portion 320 and the winding frame 110. For example, the number of lugs 3216 can be two or four, and the multiple lugs 3216 are arranged symmetrically with respect to the center of the second portion 320.
[0085] Furthermore, a mounting groove 1112 is provided on the side of the winding reel 100 connected to the second part 320. The inner peripheral wall of the mounting groove 1112 is recessed in the direction away from the center of the winding reel 100, and the second part 320 is installed in the mounting groove 1112. The end of the lug 3216 away from the first part 310 is embedded in the clearance groove 1113.
[0086] A mounting groove 1112 is provided on the connection side between the center portion 111 of the reel 100 and the second part 320. Exemplarily, the center portion 111 is cylindrical, and the mounting groove 1112 is a coaxial circular recess. The depth of the mounting groove 1112 matches the height of the second part 320, allowing the second part 320 to be completely embedded inside the center portion 111, avoiding the volume increase problem caused by the exposed damping structure 300. A relief groove 1113 is recessed on the inner peripheral wall of the mounting groove 1112. The end of the lug 3216 away from the first part 310 is embedded in the relief groove 1113. The inner peripheral wall of the mounting groove 1112 restricts the rotational offset of the second part 320. The relief groove 1113 also has a guiding function, providing clear positioning guidance for the assembly of the second part 320. The user only needs to align the lug 3216 of the second part 320 with the relief groove 1113 and push it in axially to achieve the positioning and installation of the second part 320.
[0087] Please see Figure 13 and Figure 14 In some embodiments, the outer periphery of the second part 320 is provided with a plurality of lugs 3216, and the reel 100 is provided with a mounting hole 1114 and a plurality of snap-fit grooves 1115. The snap-fit grooves 1115 are located on the outer periphery of the mounting hole 1114 and communicate with the mounting hole 1114. The second part 320 passes through the mounting hole 1114, and the plurality of lugs 3216 are inserted into the plurality of snap-fit grooves 1115 one by one.
[0088] After the second part 320 passes through the mounting hole 1114, it restricts the radial offset of the second part 320 relative to the winding frame 110, ensuring that the central axes of the two are highly coincident. Simultaneously, there are multiple lugs 3216 and corresponding multiple snap-fit grooves 1115. The multiple mating lugs 3216 and snap-fit grooves 1115 achieve circumferential positioning of the second part 320, preventing rotational offset and achieving synchronous rotation of the second part 320 and the winding frame 110. For example, the number of lugs 3216 can be two or four, and the multiple lugs 3216 are symmetrically arranged relative to the center of the second part 320.
[0089] Please see Figures 12 to 14 In some embodiments, the first portion 310 has a plug hole 312 on the side opposite to the second portion 320, and the drive shaft 211 is plugged into the plug hole 312.
[0090] The outer contour of the drive shaft 211 is adapted to the shape of the insertion hole 312, allowing the drive shaft 211 and the first part 310 to be directly connected through the insertion hole 312. During assembly, simply align the drive shaft 211 of the power component 210 with the insertion hole 312 and push it axially to complete the connection. This eliminates the need for intermediate transmission components such as couplings, reducing the number of parts, lowering production costs, and improving assembly efficiency. The elimination of intermediate transmission components also shortens the overall axial dimension of the device, reducing the volume of the wire 12 winding device.
[0091] Meanwhile, the rigid fit between the drive shaft 211 and the insertion hole 312 enables zero-backlash torque transmission, resulting in high transmission efficiency. To avoid shaft slippage due to insufficient contact in short-shaft connections, the depth to which the drive shaft 211 is inserted into the insertion hole 312 may optionally be greater than 50% of the overall axial length of the drive shaft 211, thus ensuring transmission stability.
[0092] Please see Figure 1 , Figure 2 and Figure 6 In some embodiments, the drive assembly 200 includes a power component 210 and a transmission joint 220. The power component 210 has a drive shaft 211; one end of the transmission joint 220 is provided with an input hole 221 that matches the outer contour of the drive shaft 211, and the other end is provided with an output hole 222 that matches the outer contour of the first part 310; the drive shaft 211 is inserted into the input hole 221, and the end of the first part 310 away from the second part 320 is inserted into the output hole 222, and the drive shaft 211 and the first part 310 are connected through the transmission joint 220.
[0093] like Figure 3 , Figure 4 , Figure 6 a and Figure 6As shown in Figure b, the input hole 221 of the transmission connector 220 is adapted to the outer contour of the drive shaft 211 of the drive assembly 200, and the output hole 222 is adapted to the outer contour of the first part 310. This allows for easy assembly by simply inserting the drive shaft 211 into the input hole 221 and the first part 310 into the output hole 222, thus completing the transmission connection between the drive shaft 211 and the first part 310. This simplifies assembly and significantly improves production efficiency. Specifically, the outer contours of the drive shaft 211 and the first part 310 can be D-shaped or polygonal with multiple facets.
[0094] The input port 221 and output port 222 of the transmission joint 220 can be customized according to the type of the power component 210 and the damping structure 300. Users can quickly expand the function of the device by replacing the transmission joint 220 with different specifications, and adapt the type of the power component 210 and the damping structure 300 without having to reselect the power component 210 or the damping structure 300.
[0095] Please see Figure 10 and Figure 11 In some embodiments, the drive assembly 200 includes a power element 210 and a gear set 230. The power element 210 has a drive shaft 211; the gear set 230 includes a first gear 231 and a second gear 232, the first gear 231 being connected to the drive shaft 211, and the second gear 232 being connected to the end of the first portion 310 away from the second portion 320 and meshing with the first gear 231 to cause the drive shaft 211 and the first portion 310 to rotate synchronously.
[0096] The meshing transmission between the first gear 231 and the second gear 232 achieves a rigid connection through tooth surface contact. By changing the tooth ratio between the first gear 231 and the second gear 232, the transmission ratio between the drive shaft 211 and the first part 310 can be limited, thereby adjusting the rotational speed of the first part 310.
[0097] Specifically, the power component 210 includes, but is not limited to, stepper motors, servo motors, or pneumatic motors.
[0098] In some embodiments, the wire winding device 20 further includes a voice module and a control module. The voice module is electrically connected to the control module and is used to recognize voice commands. The control module is electrically connected to the drive component 200 and is configured to control the drive component 200 to turn on and off according to the voice commands.
[0099] The voice module can collect user voice commands in real time, and after being parsed by the control module, it directly outputs electrical signals to control the start and stop of the drive component 200. Compared with traditional manual button control, voice control is more convenient and faster, greatly improving the ease of use of the wire winding device 20.
[0100] Specifically, the voice module can be a microphone, and the control module can be a circuit board. Users can record voice samples of "rewind" and "stop" into the voice module, which correspond to the control module's commands to turn the drive component 200 on and off. When the voice module recognizes the voice of "rewind" during subsequent use, the control module can automatically control the drive component 200 to turn on, so that the cable winding device 20 can perform the winding action.
