Description

[Technical Field]

[0001] This utility model relates to a winding device, and more particularly to a multi-line synchronous winding device. [Background Technology]

[0002] Currently, wire harness winding devices are widely used in various industries. However, traditional wire harness winding devices often struggle to meet the demands of simultaneous multi-wire winding, primarily due to the following problems:

[0003] 1. Difficulty in achieving synchronous winding of multiple lines: Traditional wire harness winding devices generally only have a single power winding component. When it is necessary to simultaneously wind up traction lines that connect to heavy loads and functional wire harnesses that transmit power and signals, such as power lines and signal lines, it is difficult to ensure that the two are wound and unwound synchronously. Furthermore, wire harnesses are prone to tangling, asynchronous winding and unwound, and excessive stretching of functional wire harnesses, which affects the neatness of the winding of functional wire harnesses and the normal use of devices with electrical connections.

[0004] Second, the lack of a reasonable stress adjustment mechanism means that when the functional harness is taut due to the weight load during winding, the active and passive winding components cannot adjust their speeds differentially. If forced synchronous rotation continues, the functional harness will be subjected to excessive force and stretched, causing the wire core to become thinner and increasing resistance. This will affect the transmission of current and electrical signals, easily leading to fatigue damage and breakage, severely impacting its service life and reliability. If the passive winding component cannot rotate in accordance with the active winding component due to the force, it is prone to winding tangles, knots, and other problems.

[0005] Therefore, this utility model was developed to address the aforementioned problems. [Utility Model Content]

[0006] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a multi-line synchronous winding device. The active winding assembly and the driven winding assembly achieve synchronous and differential switching through the torque transmission function of the clutch assembly. This allows the active winding assembly to drive the driven winding assembly to rotate in tandem with the mounting base, thereby achieving coordinated winding of the traction wire and the functional wire harness. This prevents the functional wire harness from being excessively stretched, effectively improving winding efficiency and ensuring coordinated winding and unwinding of the traction wire and functional wire harness in different application scenarios. It avoids problems such as tangling and knotting caused by uncoordinated winding. Furthermore, when the torque on the driven winding assembly exceeds the preset torque threshold of the clutch assembly due to the winding of the functional wire harness, the active winding assembly rotates differentially relative to the driven winding assembly. This reduces the stress on the functional wire harness, preventing damage due to excessive tension, extending the service life of the functional wire harness, ensuring its reliability and stability during long-term use, and reducing the risk of failure caused by wire harness damage.

[0007] To solve the above-mentioned technical problems, this utility model provides a multi-line synchronous winding device, including a mounting base 1. The mounting base 1 is provided with an active winding assembly 2 and a driven winding assembly 3. The active winding assembly 2 is wound with a traction wire 100 for bearing force, and the driven winding assembly 3 is wound with a non-bearing functional wire harness 200 for electrical connection. A clutch assembly 4 with a preset transmission torque threshold is provided between the driven winding assembly 3 and the active winding assembly 2. The clutch assembly 4 is configured to rotate synchronously relative to the mounting base 1 for transmitting torque from the active winding assembly 2 to the driven winding assembly 3. The clutch assembly 4 is also configured to allow the active winding assembly 2 to rotate differentially relative to the driven winding assembly 3 when the torque on the driven winding assembly 3 is greater than the preset transmission torque threshold of the clutch assembly 4, in order to prevent torque overload of the driven winding assembly 3 and thus reduce the force on the functional wire harness 200.

[0008] As described above, in a multi-line synchronous winding device, the driven winding assembly 3 is configured to rotate synchronously with the active winding assembly 2 at times and at different speeds at times, through cooperation with the clutch assembly 4 and under the action of the torque of the functional wire harness 200, ultimately achieving coordinated winding of the traction line 100 and the functional wire harness 200.

[0009] As described above, in a multi-line synchronous winding device, the clutch assembly 4 transmits a torque threshold of T1, and the driven winding assembly 3 experiences a torque of M1 from the functional wire harness 200. When the torque M1 from the functional wire harness 200 acting on the driven winding assembly 3 satisfies the torque threshold T1 of the clutch assembly 4 (M1 ≥ T1), the active winding assembly 2 rotates differentially relative to the driven winding assembly 3 to continue winding the traction line 100, thereby reducing the stress on the functional wire harness 200. When the torque M1 from the functional wire harness 200 acting on the driven winding assembly 3 satisfies the torque threshold T1 of the clutch assembly 4 (M1 < T1), the driven winding assembly 3 rotates synchronously with the active winding assembly 2, and the traction line 100 and the functional wire harness 200 are wound up accordingly.

When the torque sensing device detects that the anti-rotation torque exerted by the active winding assembly 2 on the winding spindle 11 is greater than or equal to the sensing torque threshold, the winding drive motor 1231 can be energized and started to drive the winding spindle 11 to rotate accordingly. When the torque sensing device detects that the anti-rotation torque exerted by the active winding assembly 2 on the winding spindle 11 is less than the sensing torque threshold, the winding drive motor 1231 is turned off and stops working.

The outer surface of the winding spindle 11 is provided with a spindle conductive groove 111 arranged in a ring and used to abut against the electrical guide pin 2301 on the wire harness connection terminal 230. A plug-in terminal block 13 is provided inside the winding spindle 11. One end of the plug-in terminal block 13 is electrically connected to the inner side of the spindle conductive groove 111, and the other end of the plug-in terminal block 13 is electrically connected to a conductive slip ring 14 provided on the mounting base 1. An external terminal 141 is formed at the outer end of the conductive slip ring 14.

[0019] As described above, in a multi-line synchronous winding device, the plug-in terminal block 13 includes a connecting wire 131.

[0020] As described above, in a multi-line synchronous winding device, two driven winding components 3 are symmetrically arranged on both sides of the active winding component 2. The functional wiring harness 200 includes a power line 210 wound on one driven winding component 3 and a signal line 220 wound on the other driven winding component 3.

[0021] As described above, in a multi-line synchronous winding device, the clutch assembly 4 is a friction clutch disposed between the active winding assembly 2 and the driven winding assembly 3, including an active clutch plate 41 disposed at the end of the active winding assembly 2 and a driven clutch plate 42 disposed at the end of the driven winding assembly 3 and used for frictional engagement with the active clutch plate 41.

[0024] As described above, in a multi-line synchronous winding device, the mounting base 1 is further provided with a guide device 5 for guiding the traction line 100 and the functional wire harness 200.

[0025] As described above, in a multi-line synchronous winding device, the guiding device 5 includes a guide shaft 51 rotatably mounted on a mounting base 1 for the traction line 100 and the functional wire harness 200 to pass through. The guide shaft 51 is provided with a guide spacer ring 52 for separating the traction line 100 and the functional wire harness 200.

[0026] Compared with the prior art, the present invention has the following advantages:

[0027] 1. In this invention, the active and driven winding components achieve synchronous and differential switching through the torque transmission function of the clutch component. This allows the active winding component to drive the driven winding component to rotate in tandem with the mounting base, thereby achieving coordinated winding of the traction wire and the functional harness. This prevents the functional harness from being excessively stretched, effectively improving winding efficiency and ensuring coordinated winding and unwinding of the traction wire and the functional harness in different application scenarios. It also avoids problems such as tangling and knotting caused by uncoordinated winding. Furthermore, when the torque on the driven winding component exceeds the preset torque threshold of the clutch component due to the winding of the functional harness, the active winding component rotates differentially with respect to the driven winding component. This reduces the stress on the functional harness, preventing damage due to excessive tension, extending the service life of the functional harness, ensuring its reliability and stability during long-term use, and reducing the risk of failure caused by harness damage.

[0028] 2. This utility model achieves switching between synchronous and differential speeds through a mechanical clutch assembly, eliminating the need for additional complex electrical control. It features timely response and a simple structure. At the same time, the "passive" adaptive adjustment winding mechanism of this utility model can adapt to complex working conditions. It can automatically adjust the traction line and functional harness for coordinated winding without manual intervention, significantly reducing the risk of failure due to human error or external control failure. It improves the reliability of the winding device in harsh environments or long-term use, and reduces maintenance frequency and costs.

[0029] 3. This utility model achieves coordinated winding of the traction wire and functional wire harness through the dynamic cooperation of the driven winding component and the clutch component. It can maintain synchronization under normal working conditions to ensure that the traction wire and functional wire harness are neatly arranged, and can protect the functional wire harness through differential speed buffer under abnormal working conditions, that is, avoid the functional wire harness being subjected to force and being excessively pulled. Therefore, this utility model replaces complex control logic with mechanical structure, taking into account reliability, adaptability, durability and economy, and provides a better solution for multi-wire harness winding scenarios.

[0030] 4. The active take-up reel and the take-up spindle are fixedly connected by a keyway structure, which can provide a stable and reliable torque transmission capability, ensure synchronous rotation between the active take-up reel and the take-up spindle, prevent slippage, and enable the traction line to be stably wound on the active take-up reel during the take-up process, effectively improving the strength of the connection structure.

[0031] 5. This utility model has an electric drive component and a manual drive component, providing a flexible driving method for the winding device; under normal circumstances, the electric drive component can be used for efficient and convenient winding operation; when encountering power failure, damage to the electric drive component, or the need for manual adjustment, the manual drive component can serve as a backup solution to ensure the normal operation of the winding device and improve the reliability, practicality, and adaptability of the winding device.

[0032] 6. The winding drive motor and winding drive gear are mounted on the mounting base and together with the winding gear set and other components, form a relatively compact winding drive mechanism. This helps to save space, making the structure of the entire winding device more compact and reasonable, and facilitating installation and coordination with other components.

[0033] 7. This utility model rotatably mounts the driven take-up wheel onto the take-up spindle, and simultaneously sets up a plug-in terminal block inside the take-up spindle, which is connected to the outside through a conductive slip ring. This makes the entire driven take-up assembly more compact and reasonable in terms of spatial layout. The components cooperate with each other, making full use of the internal space of the take-up spindle, reducing the additional space occupied and the inertia of the take-up spindle, making the entire take-up device lighter and easier to install in different equipment. In addition, the cooperation between the conductive slip groove of the spindle and the electrical guide pin can adapt to the dynamic changes of the driven take-up wheel, maintaining good electrical contact at all times during the rotation of the take-up spindle. It will not cause problems such as loosening or failure of connection due to movement, ensuring the stability and reliability of the take-up device in dynamic working conditions.

[0034] 8. This utility model separates the power lines and signal lines in the functional wire harness and winds them onto two driven winding components symmetrical to the moving winding wheel. This achieves physical isolation management of the power lines and signal lines. This physically isolated winding method avoids the power lines and signal lines from being wound together on the same winding wheel, thus effectively avoiding electromagnetic interference from the power lines to the signal lines, improving the stability of signal transmission, ensuring the normal operation of external devices and reliable signal transmission and reception, and facilitating the separate installation, maintenance and replacement of different types of wire harnesses. It also facilitates the quick location and handling of wire harness-related faults during subsequent use.

[0035] 9. The guiding device ensures that the traction line and functional harness run accurately along the predetermined path, avoiding problems such as deviation, skewing or tangling during winding and unwinding. This allows the traction line and functional harness to be wound neatly, orderly and collaboratively on the corresponding winding reels, improving winding quality and efficiency.

[0036] 10. This utility model enables the winding drive motor to be energized and start when the torque sensing device detects that the anti-rotation torque exerted by the active winding assembly on the winding spindle is greater than or equal to the sensing torque threshold, thereby driving the winding spindle to rotate accordingly; when the torque sensing device detects that the anti-rotation torque exerted by the active winding assembly on the winding spindle is less than the sensing torque threshold, the winding drive motor is shut off and stops working. This effectively prevents the non-stressed functional harness from bearing the pulled object completely after the stressed traction line breaks, avoiding damage due to excessive stress on the functional harness; or, when the motor is not started or stopped, a signal can be issued to prompt the user to check the connection status of the stressed traction line, to prevent damage to the non-stressed functional harness due to the failure of the stressed traction line, ensuring the normal use of the functional harness and the reliability of traction.

Detailed Implementation Methods

[0053] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0054] like Figure 1-15 As shown, this utility model discloses a multi-line synchronous winding device, including a mounting base 1. The mounting base 1 is provided with an active winding assembly 2 and a driven winding assembly 3. The active winding assembly 2 is wound with a traction line 100 for bearing force, and the driven winding assembly 3 is wound with a non-bearing functional wire harness 200 for electrical connection. A clutch assembly 4 with a preset transmission torque threshold is provided between the driven winding assembly 3 and the active winding assembly 2. The clutch assembly 4 is configured to rotate synchronously relative to the mounting base 1 for transmitting torque from the active winding assembly 2 to the driven winding assembly 3. The clutch assembly 4 is also configured to allow the active winding assembly 2 to rotate differentially relative to the driven winding assembly 3 when the torque on the driven winding assembly 3 exceeds the preset transmission torque threshold of the clutch assembly 4, in order to prevent torque overload of the driven winding assembly 3 and thus reduce the force on the functional wire harness 200. In this invention, the active and driven winding components achieve synchronous and differential switching via the torque transmission function of the clutch assembly. This allows the active winding component to drive the driven winding component to rotate in tandem with the mounting base, thus achieving coordinated winding of the traction wire and functional harness. This prevents the functional harness from being excessively stretched, effectively improving winding efficiency and ensuring coordinated winding and unwinding of the traction wire and functional harness in different application scenarios. It also avoids problems such as tangling, knotting, and other defects caused by uncoordinated winding. Furthermore, when the torque on the driven winding component exceeds the preset torque threshold of the clutch assembly due to the functional harness being wound by the driven winding component, the active winding component rotates differentially with respect to the driven winding component. This reduces the stress on the functional harness, preventing damage from excessive tension, extending the service life of the functional harness, ensuring its reliability and stability during long-term use, and reducing the risk of failure caused by harness damage.

[0055] This utility model of a multi-line synchronous winding device is applicable to various occasions that require simultaneous winding of traction lines and functional wire harnesses, such as medical equipment, industrial automation equipment, communication equipment, fishing buoyancy platforms, etc. Its synchronous winding and differential protection functions can meet the requirements of different equipment for wire harness winding, and have broad application prospects and versatility.

[0056] In this invention, the load-bearing traction wire can be interpreted as: a wire harness that directly or primarily bears weight loads and traction forces, used for traction or carrying counterweight loads. The non-load-bearing functional wire harness can be interpreted as: a wire harness that does not primarily bear traction forces or loads, and whose main function may be for power transmission, signal transmission, auxiliary traction, or other non-load-bearing functions.

[0057] The clutch assembly 4 in this utility model has a transmission torque threshold, which refers to the maximum torque that the clutch assembly can stably and reliably transmit under normal working conditions. The preset transmission torque threshold is set within a corresponding range according to the needs of the clutch assembly 4. Therefore, the preset transmission torque threshold can be adjusted according to the usage requirements to achieve different torque transmission requirements.

[0058] The driven winding assembly 3, through its cooperation with the clutch assembly 4 and the torque exerted by the functional wire harness 200, is configured to rotate synchronously with the active winding assembly 2 at times and differentially at times, ultimately achieving coordinated winding of the traction line 100 and the functional wire harness 200. This embodiment achieves coordinated winding of the traction line and functional wire harness through the dynamic cooperation of the driven winding assembly and the clutch assembly—maintaining synchronization under normal operating conditions to ensure neat arrangement of the traction line and functional wire harness, while protecting the functional wire harness under abnormal operating conditions through differential buffering, thus preventing excessive pulling on the functional wire harness. Therefore, this invention replaces complex control logic with a mechanical structure, taking into account reliability, adaptability, durability, and economy, providing a superior solution for multi-wire harness winding scenarios.

[0059] In this embodiment, the driven winding assembly rotates synchronously with the active winding assembly and at different speeds depending on the stress on the functional harness. This balancing mechanism ensures that, in most cases, the traction wire and the functional harness can be wound at similar speeds, maintaining coordination between them. In special cases where the functional harness is under tension, the differential rotation can promptly reduce the stress on the functional harness and prevent damage, thus achieving good adaptability to different working conditions.

[0060] The clutch assembly 4 transmits a torque threshold of T1, and the driven winding assembly 3 experiences a torque of M1 from the functional harness 200. When the torque M1 from the functional harness 200 acting on the driven winding assembly 3 and the torque threshold T1 of the clutch assembly 4 satisfy the condition that M1 ≥ T1, the active winding assembly 2 rotates differentially relative to the driven winding assembly 3 to continue winding the traction line 100, thereby reducing the stress on the functional harness 200. When the torque M1 from the functional harness 200 acting on the driven winding assembly 3 and the torque threshold T1 of the clutch assembly 4 satisfy the condition that M1 < T1, the driven winding assembly 3 rotates synchronously with the active winding assembly 2, and the traction line 100 and the functional harness 200 are wound up accordingly. This design in this embodiment enables the winding device to automatically adjust the winding mode according to actual conditions, enhancing the adaptive capability of the winding device, reducing the risk of failure due to torque mismatch, and improving the reliability and stability of the entire winding device.

[0061] The mounting base 1 is provided with a winding drive motor 1231 for driving the winding spindle 11 to rotate accordingly. The winding drive motor 1231 is preferably a servo motor to ensure precise control of the winding of the functional harness and the traction wire. The winding spindle 11 is equipped with a torque sensing device. When the torque sensing device detects that the anti-rotation torque exerted by the active winding assembly 2 on the winding spindle 11 is greater than or equal to the sensing torque threshold, the winding drive motor 1231 can be energized and started to drive the winding spindle 11 to rotate accordingly. When the torque sensing device detects that the anti-rotation torque exerted by the active winding assembly 2 on the winding spindle 11 is less than the sensing torque threshold, the winding drive motor 1231 is turned off and stops working. This effectively prevents the non-stressed functional harness from bearing the pulled object completely after the stressed traction line breaks, avoiding damage due to excessive stress on the functional harness. Alternatively, when the motor is not started or stopped, a signal can be issued to prompt the user to check the connection status of the stressed traction line to prevent damage to the non-stressed functional harness due to the failure of the stressed traction line, ensuring the normal use of the functional harness and the reliability of pulling. The torque sensing device is a torque sensor, which can be a commercially available torque sensor, such as the HBMT22 torque sensor. In this embodiment, the anti-rotation torque can be understood as the torque generated on the winding main shaft 11 by the traction line wound on the active winding assembly 2 when the winding main shaft 11 rotates, which is opposite to the direction of rotation.

[0062] like Figure 1-7As shown, a winding spindle 11 is rotatably mounted on the mounting base 1, and a winding drive mechanism 12 is provided on the mounting base 1 to drive the winding spindle 11 to rotate accordingly. The active winding assembly 2 is relatively fixedly mounted on the winding spindle 11 and rotates accordingly with the winding spindle 11, while the driven winding assembly 3 is rotatably mounted on the winding spindle 11. This winding spindle not only supports the active winding assembly but also provides a mounting base for the driven winding assembly, making the layout of the entire winding device compact, reducing the space occupied, facilitating the implementation of multi-line winding functions in a limited space, and simplifying the overall structure of the winding device. It eliminates the need for complex transmission mechanisms to achieve the independent movement of the active and driven winding assemblies, reducing manufacturing costs and maintenance difficulty.

[0063] like Figure 3 , 4 As shown in Figures 7 and 11, the active winding assembly 2 includes an active winding wheel 21 sleeved on the winding spindle 11. The active winding wheel 21 is fixedly connected to the winding spindle 11 via a keyway structure 22. A blocking and fixing ring 23 is provided on the side of the active winding wheel 21 to prevent it from sliding along the axial direction of the winding spindle 11. The traction line 100 is wound around the active winding wheel 21. In this embodiment, the active winding wheel is fixedly connected to the winding spindle via the keyway structure, ensuring stable rotation of the active winding wheel with the winding spindle, avoiding relative sliding, and ensuring smooth and continuous winding action. Simultaneously, the blocking and fixing rings on both sides of the active winding wheel, in conjunction with the corresponding ends of the keyway structure, effectively prevent the active winding wheel from sliding along the axial direction of the winding spindle, ensuring its precise position and the stability of the winding process. Furthermore, when installing the active winding wheel, the blocking and fixing rings can serve as a positioning reference to quickly determine its accurate position, facilitating installation.

[0064] like Figure 5-7 As shown in Figure 10, the driven winding assembly 3 includes a driven winding wheel 31 rotatably sleeved on the winding spindle 11. The winding spindle 11 is provided with a blocking end cap 32 for preventing the driven winding wheel 31 from sliding along the axial direction of the winding spindle 11. In this embodiment, one end of the driven winding wheel 31 is in frictional engagement with the driving winding wheel through a clutch assembly, and the other end is correspondingly blocked and limited by the blocking end cap 32. This effectively prevents the driven winding wheel from moving in the axial direction of the winding spindle, ensuring the stability of the driven winding wheel's position during the winding process, avoiding problems such as uneven winding and wire tangling caused by axial displacement, and improving the winding quality.

[0065] like Figure 5-7 As shown, the driven take-up roller 31 is sleeved on the take-up spindle 11 through the self-sliding bushing 310, which can significantly reduce the frictional resistance between the driven take-up roller and the take-up spindle, making the driven take-up roller rotate more smoothly on the take-up spindle, reducing energy loss caused by friction, and improving the transmission efficiency of the take-up device.

[0066] like Figure 1 , 2 As shown in Figures 7 and 8, the winding drive mechanism 12 includes a winding gear set 121 rotatably mounted on the mounting base 1. The winding gear set 121 is movably connected to the winding spindle 11 via a winding transmission component 122. The winding drive mechanism 12 also includes an electric drive assembly 123 and / or a manual drive assembly 124 mounted on the mounting base 1 for driving the winding gear set 121 to rotate accordingly. This embodiment provides both an electric drive assembly and a manual drive assembly, offering a flexible driving method for the winding device. Under normal circumstances, the electric drive assembly can be used for efficient and convenient winding operations. When encountering power failures, damage to the electric drive assembly, or the need for manual adjustment, the manual drive assembly can serve as a backup solution, ensuring the normal operation of the winding device and improving its reliability, practicality, and adaptability.

[0067] like Figure 3-8 As shown, a winding elastic element 125 is provided between the winding drive component 122 and the winding gear set 121 to ensure that the winding drive component 122 and the winding main shaft 11 maintain a synchronous connection, which can effectively buffer the impact force between the winding drive component and the winding main shaft. During the winding process, especially when the winding drive mechanism starts or stops, a large impact torque may be generated. The winding elastic element can absorb this impact force, making the rotation of the winding main shaft smoother and reducing the risk of component wear and damage caused by impact. In addition, during actual installation and operation, there may be a certain axial deviation or angular deviation. The winding elastic element can compensate for these deviations to a certain extent, ensuring that the winding drive component and the winding main shaft always maintain a reliable synchronous connection. Even in the case of small displacement or deviation, the elastic deformation of the winding elastic element can ensure that the connection is not broken and maintain the continuity of power transmission.

[0068] like Figure 7 , 8 As shown, the electric drive assembly 123 includes a take-up drive motor 1231 mounted on the mounting base 1. The motor shaft of the take-up drive motor 1231 is movably connected to a take-up drive gear 1232 for meshing and transmission with the take-up gear set 121. This effectively transmits the power of the drive motor to the take-up spindle, enabling the take-up of the traction line. Simultaneously, the gear transmission has the characteristic of high transmission efficiency, reducing power loss during transmission and ensuring that the take-up spindle receives sufficient torque to drive the drive take-up wheel to stably take up the traction line.

[0069] like Figure 1-8As shown, for ease of use, the manual drive assembly 124 includes a manual shaft 1241 rotatably mounted on the mounting base 1. One end of the manual shaft 1241 is formed with a drive connection end 1242 for connecting and driving a manual handle, and the other end of the manual shaft 1241 is provided with a manual drive gear 1243 for meshing and transmitting with the winding gear set 121.

[0070] like Figure 8 As shown, the winding gear set 121 includes, but is not limited to, a main drive gear 1211 mounted on the mounting base 1 and meshing with both the winding drive gear 1232 and the manual drive gear 1243. The main drive gear 1211 is movably connected to a secondary drive gear 1212. The mounting base 1 is provided with a shaft drive gear 1213 meshing with the secondary drive gear 1212, and the outer diameter of the shaft drive gear 1213 is larger than the outer diameter of the secondary drive gear 1212. The corresponding end of the winding transmission component 122 is movably connected to the shaft drive gear 1213. The larger outer diameter of the shaft drive gear allows for greater torque output during transmission through speed reduction, enabling easier winding of the traction cable, especially in situations requiring greater winding force, such as winding heavy traction cables or when the traction cable is subjected to a large weight load.

[0071] like Figure 8 As shown, the winding drive gear 1232, the manual drive gear 1243, and the main drive gear 1211 are all bevel gears. The special shape of the bevel gears allows for flexible arrangement within a limited space, providing more space optimization possibilities for the design of the winding device, making the overall structure more compact and reasonable, and is especially suitable for miniaturized winding devices.

[0072] like Figure 1 , 2 As shown, the two driven reel assemblies 3 are symmetrically arranged on both sides of the active reel 2. The functional harness 200 includes a power line 210 wound on one driven reel 3 and a signal line 220 wound on the other driven reel 3. By winding the power line and signal line of the functional harness on two driven reel assemblies symmetrical to the active reel, physical isolation management of the power line and signal line is achieved. This physically isolated winding method avoids the power line and signal line from being wound together on the same reel, thus effectively avoiding electromagnetic interference from the power line to the signal line, improving the stability of signal transmission, ensuring the normal operation of external devices and reliable signal transmission and reception, and facilitating the individual installation, maintenance, and replacement of different types of harnesses. It also facilitates the quick location and handling of harness-related faults during subsequent use.

[0073] like Figure 3 , 4As shown in Figures 7, 10, 12, and 13, the driven take-up assembly 3 includes a driven take-up wheel 31 rotatably mounted on the take-up spindle 11. The driven take-up wheel 31 has a terminal connection portion 311 for inserting and fixing the wire harness connection terminal 230 of the functional wire harness 200. The outer surface of the take-up spindle 11 has a ring-shaped conductive groove 111 for engaging with the electrical guide pin 2301 on the wire harness connection terminal 230. A connector 13 is provided inside the take-up spindle 11. One end of the connector 13 is electrically connected to the inner side of the conductive groove 111, and the other end is electrically connected to a conductive slip ring 14 provided on the mounting base 1. An external terminal 141 is formed at the outer end of the conductive slip ring 14. The conductive slip ring 14 can be a Senruipu JSR-RAH030 series conductive slip ring, etc. The plug-in terminal block 13 includes a connecting wire 131. One end of the connecting wire 131 is provided with a wire connecting terminal 132 for plugging into the wire connecting part 112 inside the winding spindle 11. The wire connecting terminal 132 is provided with a wire connecting guide pin 133 for electrically connecting to the inside of the conductive slide groove 111 of the spindle. The other end of the connecting wire 131 is provided with a wire connecting part 134 for electrically connecting to the rotating connecting end 142 of the conductive slip ring 14. By rotatably mounting the driven take-up reel onto the take-up spindle, and simultaneously installing a plug-in terminal block inside the take-up spindle and connecting it to the outside via a conductive slip ring, the entire driven take-up assembly can be made more compact and rational in terms of spatial layout. The components cooperate with each other, making full use of the internal space of the take-up spindle, reducing additional space occupation and take-up spindle inertia, making the entire take-up device lighter and easier to install in different equipment. In addition, the cooperation between the main shaft conductive groove and the electrical guide pin can adapt to the dynamic changes of the driven take-up reel, maintaining good electrical contact at all times during the rotation of the take-up spindle, and preventing problems such as loosening or failure of connection due to movement, thus ensuring the stability and reliability of the take-up device under dynamic working conditions.

[0074] like Figure 3 , 4 As shown in Figure 7, the clutch assembly 4 is a friction clutch disposed between the active winding assembly 2 and the driven winding assembly 3, including an active clutch plate 41 disposed at the end of the active winding assembly 2 and a driven clutch plate 42 disposed at the end of the driven winding assembly 3 for frictional engagement with the active clutch plate 41. In some embodiments, the driven clutch plate 42 is configured to be adjustable. By adjusting the clamping force between the active clutch plate and the driven clutch plate, the maximum torque transmitted by the friction clutch can be easily changed, enabling the winding device to flexibly adjust the torque according to different winding requirements and working conditions, thereby achieving precise control of the winding force and meeting diverse working needs.

[0075] like Figure 5 , 8As shown, the driven clutch plate 42 is slidably mounted on the driven retractor assembly 3. A clutch elastic element 43 is provided between the driven clutch plate 42 and the driven retractor assembly 3 to maintain frictional engagement between the driven clutch plate 42 and the driving clutch plate 41. This element automatically compensates for wear of the driven clutch plate during use. As the driven clutch plate wears, the clutch elastic element continuously provides pressure, ensuring good contact between the driven and driving clutch plates, maintaining stable friction, and thus maintaining the clutch's torque transmission capability and extending its service life. Furthermore, the pressure of the clutch elastic element can be adjusted according to actual needs. For example, by adjusting the preload of the elastic element or replacing it with an elastic element of different stiffness, the pressure between the driven and driving clutch plates can be changed to adapt to different torque transmission requirements or operating conditions, enhancing the clutch's flexibility and adjustability.

[0076] like Figure 5 , 8 As shown, for ease of adjustment, the driven winding assembly 3 is provided with a compression adjustment assembly 44 for compressing the clutch elastic element 43. The compression adjustment assembly 44 includes a compression adjustment rod that is movably and adjustablely connected to the driven winding assembly 3. The free end of the compression adjustment rod abuts against the corresponding end of the clutch elastic element 43.

[0077] like Figure 1 , 2 As shown, the mounting base 1 is also provided with a guide device 5 for guiding the traction line 100 and the functional wire harness 200, which can ensure that the traction line and the functional wire harness run accurately along the predetermined path, avoid problems such as deviation, skewness or entanglement during winding and unwinding, and enable the wire harness to be neatly and orderly wound on the winding wheel, thereby improving winding efficiency and quality.

[0078] like Figure 1 , 2 As shown, the guiding device 5 includes a guide shaft 51 rotatably mounted on the mounting base 1 for the traction wire 100 and the functional wire harness 200 to pass through. The guide shaft 51 has a guide spacer 52 for separating the traction wire 100 and the functional wire harness 200. The rotatable mounting of the guide shaft on the mounting base allows the traction wire and functional wire harness to slide smoothly as they pass through the guide shaft, reducing frictional resistance between the wire harness and the guiding device. This helps reduce energy loss, improve the transmission efficiency of the winding device, extend the service life of the wire harness and the guiding device, and reduce maintenance costs.
