[0045] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0046] Please refer to Figure 1-Figure 6 The present embodiment provides a cable follow-up retractable device, comprising a housing 1, a fixed cylinder 2, a driving assembly 3, a cable winding wheel 4, a cable reel base wheel 5, and a controller 6. The fixed cylinder 2 is arranged inside the housing 1, a thread is arranged on the outside of the fixed cylinder 2, a mounting cavity 21 is arranged inside the fixed cylinder 2, the driving assembly 2 is arranged in the mounting cavity 21, one end of the cable winding wheel 4 is threadedly connected to the outside of the fixed cylinder 2, the cable reel base wheel 5 is arranged at the other end of the cable winding wheel 4, the cable reel base wheel 5 is transmission-connected to the driving assembly 3, the cable winding wheel 4 and the cable reel base wheel 5 have the degree of freedom of axial linear motion, the controller 6 is arranged in the fixed cylinder 2, and the controller 6 is electrically connected to the driving assembly 3.

[0047] In this embodiment, when it is necessary to reel in or release the cable, the controller 6 controls the drive component 3 to start, and the drive component 3 drives the cable drum base wheel 5 to rotate. The rotation of the cable drum base wheel 5 drives the cable winding wheel 4 to make a spiral motion along the fixed cylinder 2, thereby reeling in or releasing the cable. Moreover, the reeling and releasing device of this embodiment is single-layer winding, which has a smaller diameter than the traditional multi-layer winding, and is conducive to product arrangement under limited space requirements.

[0048] The various structures of the present embodiment can be connected by bolts, and the casing 1, the fixing cylinder 2, the driving assembly 3, the cable winding wheel 4, and the cable reel base wheel 5 can all be modularized. When it is necessary to reel in and out cables of different wire diameters and reeling lengths, different fixing cylinders 2 and cable winding wheels 4 can be replaced to meet the use requirements of different products.

[0049] Specifically, the housing 1 includes a left end plate 11, a right end plate 12, a top plate 13, a bottom plate 14, a front sealing cover 15 and a rear sealing cover 16. The left end plate 11, the right end plate 12, the top plate 13, and the bottom plate 14 are spliced ​​into a rectangular frame. The front sealing cover 15 and the rear sealing cover 16 are arranged on the front and rear sides of the rectangular frame to seal the rectangular frame. Other structures can be completely accommodated in the housing 1, and have the functions of installation positioning and overall protection. The installation position can be adjusted according to the direction of the cable to ensure the orderly collection of the cables. The structure is compact and occupies a small space. In addition, a mounting plate 17 is also provided on the housing 1. The entire device can be installed on the lifting mechanism through the mounting plate 17. One end of the cable is fixedly connected to the product base, and the other end moves with the lifting mechanism. The wire-reeling device can move synchronously with the speed of the lifting mechanism. The cable is subjected to little force, and the cable collection is stable and reliable.

[0050] In this embodiment, the fixing tube 2 is fixed to the right end plate 12 via the end cover 22 .

[0051] Please refer to Figure 2-Figure 4 The driving assembly 3 includes a motor mounting frame 31, a driving motor 32, and a speed reduction mechanism 33. The motor mounting frame 31 is arranged in the housing 1, the driving motor 32 is arranged on the motor mounting frame 31, the speed reduction mechanism 33 is transmission-connected to the output end of the driving motor 32, and one end of the speed reduction mechanism 33 away from the driving motor 32 is transmission-connected to the cable drum base wheel 5.

[0052] For details, please refer to Figure 4 The speed reduction mechanism 33 includes a fixed rigid wheel 331, a flexible wheel 332, a flexible bearing 333, a wave generator 334, an output rigid wheel 335, an output shaft 336 and a housing cover 337. The fixed rigid wheel 331 is arranged on the inner wall of the fixed cylinder 2, one side of which is fixedly connected to the driving motor 32, the flexible wheel 332 is arranged on the inner side of the fixed rigid wheel 331, the flexible bearing 333 is arranged on the inner side of the flexible wheel 332, the wave generator 334 is arranged on the inner side of the flexible bearing 333, one end of the output rigid wheel 335 is transmission-connected to the flexible wheel 332, one end of the output shaft 336 is transmission-connected to the other end of the output rigid wheel 335, and the other end of the output shaft 336 is transmission-connected to the cable drum base wheel 5.

[0053] Specifically, one end of the motor mounting frame 31 is connected to the end cover 22, and the other end is connected to the fixed rigid wheel 331. The fixed rigid wheel 331, the flexible wheel 332, the flexible bearing 333, and the wave generator 334 form a harmonic reducer. The internal teeth of the fixed rigid wheel 331 and the external teeth of the flexible wheel 332 have a difference in the number of teeth. The wave generator 334 is a rod-shaped component, on which the flexible bearing 333 is mounted to form a roller, and is pressed against the inner wall of the flexible wheel 332. The flexible wheel 332 is a thin-walled gear that can produce a large elastic deformation, and its inner hole diameter is slightly smaller than the total length of the wave generator 334. The wave generator 334 is a component that enables the flexible wheel 332 to produce controllable elastic deformation. When the wave generator 334 is installed in the flexible wheel 332, the cross-section of the flexible wheel 332 is forced to change from the original circular shape to an ellipse, and the teeth near the two ends of its long axis are fully meshed with the teeth of the fixed rigid wheel 331, while the teeth near the two ends of the short axis are completely disengaged from the fixed rigid wheel 331. The teeth of other sections on the circumference are in a transitional state of engagement and disengagement. When the wave generator 334 rotates continuously, the deformation of the flexible wheel 332 is constantly changing, so that the meshing state of the flexible wheel 332 and the fixed rigid wheel 331 is also constantly changing, from engagement, engagement, disengagement, disengagement, and engagement again..., repeating over and over again, thereby realizing the slow rotation of the flexible wheel 332 relative to the fixed rigid wheel 331 in the opposite direction of the wave generator, thereby realizing the deceleration rotation function. In this embodiment, the flexible wheel 332 has the same number of teeth as the output rigid wheel 335, and moves synchronously.

[0054] Of course, the speed reduction mechanism 33 is not limited to the use of a harmonic speed reducer, and a mechanism such as a planetary speed reducer that can achieve motor speed reduction can also be used.

[0055] Preferably, the outer shell cover 337 is disposed on the other side of the fixed rigid wheel 331 , and the output shaft 336 passes through the outer shell cover 337 and can rotate relative to the outer shell cover 337 to provide support for the output shaft 336 .

[0056] Please refer to Figure 5 and Figure 6 The outer side of the cable drum base wheel 5 is provided with a plurality of sliding blocks 51 along its circumferential direction, the inner side of the cable winding wheel 4 is provided with a plurality of guide grooves 41 along its axial direction, the plurality of guide grooves 41 correspond to the plurality of sliding blocks 51 one by one, the inner side of the cable winding wheel 4 away from the end of the cable drum base wheel 5 is provided with a fixing ring 42, the inner side of the fixing ring 42 is threadedly connected with the outer side of the fixing cylinder 2. The radial movement of the cable winding wheel 4 is guided by the mutual cooperation between the guide groove 41 and the sliding block 51.

[0057] Baffles 43 are provided on both sides of the cable winding wheel 4 to ensure that the cable is wound on the cable winding wheel 4 and prevent the cable from coming out. The pitch of the thread on the fixed cylinder 2 is equal to the diameter of the cable, and the axial displacement of the cable winding wheel 4 per rotation is equal to the diameter of the wound cable, ensuring that the cable entering the cable winding wheel 4 from the fixed position is wound in a single layer in an orderly manner.

[0058] The follow-up wire-retracting and -releasing device of this embodiment also includes a slip ring 7, one end of which is connected to the cable drum base wheel 5 by transmission, and the other end is fixedly connected to the side wall of the housing 1. The slip ring 7 is connected to the rotating body and transmits energy and signals; specifically, the slip ring 7 is mainly composed of two major parts, a rotating part and a stationary part. The rotating part is connected to the cable drum base wheel 5 by transmission, and the cable drum base wheel 5 drives the rotating part of the slip ring 7 to rotate, and the stationary part is fixedly connected to the side wall of the housing 1; at the same time, the slip ring 7 ensures that when the cable winding wheel 4 makes a spiral motion along the fixed cylinder 2 (that is, the cable is in the winding process), the cable winding wheel 4 has enough space to complete the single-layer winding; the slip ring 7 is directly obtained from the prior art, and its structure is not specifically described in this application, but it does not mean that it cannot be realized.

[0059] Preferably, it also includes a cable guide wheel 8, which is fixed to the outside of the housing 1 through a fixing seat 81, and a through hole for the cable to pass through is provided on the housing 1. The cable guide wheel 8 assists in completing the cable retracting action, ensuring that the position of the cable entering the cable winding wheel 4 is stable at the designed position.

[0060] To sum up, in this embodiment, the driving component 3 and the cable reel base wheel 5 cooperate with each other to drive the cable winding wheel 4 to make a spiral motion around the fixed tube 2, and then reel up the cable, ensuring a single-layer spiral winding of the cable to avoid cable jamming, and can be modularly assembled according to different wire diameters and retracted lengths to meet usage requirements.
