Description

Technical Field

[0001] This application relates to the field of winding devices, and in particular to a locking mechanism and a winding device. Background Technology

[0002] Winding reels are used to wind cables to achieve cable winding. Winding equipment automates cable winding by driving the winding reel to rotate, helping users to wind cables quickly and conveniently. Furthermore, the winding reel can be equipped with a locking mechanism to prevent the reel from rotating, thus adapting to corresponding functional requirements.

[0003] However, the common locking method is to set a locking mechanism on the outside of the winding wheel, which locks the winding wheel from the outside. This setting increases the internal space requirement of the winding device and increases the size of the winding device. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0024] Please refer to Figure 1 This application provides a locking mechanism 220 for limiting the rotation of the winding reel 210. The following describes the cooperation between the winding reel 210 and the locking mechanism 220; please refer to [reference needed]. Figure 2 and Figure 3 The winding reel 210 has a hollow cavity 20, which is arranged along the axis P of the winding reel 210. The end of the winding reel 210 has an opening 210C communicating with the hollow cavity 20. The hollow cavity 20 extends along the axis P of the winding reel 210 and has an opening at the end of the winding reel 210, so that the center position of the winding reel 210 is used as a space to cooperate with the locking mechanism 220, which facilitates the assembly with the locking mechanism 220. In addition, this arrangement can also reduce the impact on the dynamic balance of the winding reel 210 after the winding reel 210 and the locking mechanism 220 are assembled, and improve the rotational stability of the winding reel 210.

[0025] Please continue to refer to this. Figure 4 The locking mechanism 220 includes a locking drive assembly 24 and an abutment assembly 25 tractively connected to the locking drive assembly 24. At least a portion of the abutment assembly 25 extends into the hollow cavity 20 through an opening. The locking drive assembly 24 is configured to drive the abutment assembly 25 to abut against the cavity wall of the hollow cavity 20 radially along the winding wheel 210. With this configuration, the locking mechanism 220 can brake the winding wheel 210 from within, which reduces the space occupied by the locking mechanism 220 compared to braking the winding wheel 210 from the outside. This reduces the overall structural size and also protects the abutment assembly 25 of the locking mechanism 220 using the winding wheel 210. For example, using this design in the fitness equipment 10000 can further reduce the internal space requirements of the fitness equipment 10000, making the overall layout of the fitness equipment 10000 more compact.

[0026] Furthermore, with this configuration, the locking drive assembly 24 drives the abutment assembly 25 to move, thereby generating friction by contacting the cavity wall of the hollow cavity 20 radially along the winding wheel 210 within the hollow cavity 20. The locking drive assembly 24 controls the pressure applied radially to the cavity wall of the hollow cavity 20 by the abutment assembly 25, gradually increasing or decreasing the friction, ultimately stopping the winding wheel 210 and locking it in place. This configuration also allows for linear control of the friction force, gradually stopping the winding wheel 210, avoiding the direct, instantaneous halting of its rotation using mechanical structures, thus reducing damage or impact on the reel motor driving the winding wheel 210.

[0027] In some embodiments, the structure of the abutment component 25 is further optimized; please refer to [reference needed]. Figures 5 to 7 The abutment assembly 25 may include an abutment transmission member 251 and multiple moving members 252. The abutment transmission member 251 may be driveably connected to the locking drive assembly 24, and the multiple moving members 252 may be arranged around an axis and may be driveably connected to the abutment transmission member 251 respectively. The abutment transmission member 251 may be configured to move under the drive of the locking drive assembly 24, thereby causing the multiple moving members 252 to synchronously approach and / or move away from the cavity wall of the hollow cavity 20 along their respective corresponding radial directions. In these embodiments, multiple moving members 252 are used and move synchronously under the drive of the abutment transmission member 251 to synchronously and uniformly abut against the cavity wall of the hollow cavity 20 around the axis. This ensures uniform force on the cavity wall of the hollow cavity 20 and increases the contact area between the abutment assembly 25 and the cavity wall of the hollow cavity 20, which is beneficial for increasing friction and improving braking stability.

[0028] The method of braking the winding wheel 210 is further described by the abutment transmission member 251 by "driving multiple moving members 252 to move synchronously toward and / or away from the cavity wall of the hollow cavity 20 along their respective corresponding radial directions".

[0029] In some embodiments, the abutment drive member 251 can be configured to, under the drive of the locking drive assembly 24, simultaneously drive multiple moving members 252 to approach the cavity wall of the hollow cavity 20 along their respective corresponding radial directions, so as to uniformly abut against the cavity wall of the hollow cavity 20 and gradually increase the pressure applied to the cavity wall, thereby braking the winding wheel 210. Simultaneously, the abutment drive member 251 can also be configured to, under the drive of the locking drive assembly 24, drive multiple moving members 252 to simultaneously move away from the cavity wall of the hollow cavity 20 along their respective corresponding radial directions, thereby disengaging the braking of the winding wheel 210, at which point the winding wheel 210 can rotate normally. With this configuration, the locking drive assembly 24 can drive the abutment drive member 251 to move the moving members 252 back and forth radially.

[0030] In other embodiments, please refer to Figure 5 The locking mechanism 220 may further include a first elastic element 281. One end of the first elastic element 281 may be connected to the side of the moving member 252 away from the cavity wall, and the other end may be fixed to another moving member 252 or the axis P. Thus, the first elastic element 281 may be configured to use its own elasticity to drive the moving member 252 to press against the cavity wall of the hollow cavity 20 and to uniformly abut against the cavity wall of the hollow cavity 20, so as to maintain the braking of the winding wheel 210. Furthermore, the abutment transmission member 251 may be configured to drive multiple moving members 252 synchronously away from the cavity wall of the hollow cavity 20 along their respective corresponding radial directions under the drive of the locking drive assembly 24, so as to drive the moving members 252 to gradually move away from the cavity wall of the hollow cavity 20, thereby disengaging the braking of the winding wheel 210. With this setting, in the initial state, the locking mechanism 220 is in a locked state on the winding wheel 210. When it is not necessary to lock the winding wheel 210, the locking drive assembly 24 can be activated to drive the moving part 252 to gradually disengage from the brake on the winding wheel 210.

[0031] In some other embodiments, please refer to Figure 6 The locking mechanism 220 may also include a second elastic element 282. One end of the second elastic element 282 may be connected to the side of the moving member 252 away from the cavity wall, and the other end may be fixed to another moving member 252 or the axis P. Thus, the second elastic element 282 may be configured to use its own elasticity to drive the moving member 252 away from the cavity wall of the hollow cavity 20. Furthermore, the abutment transmission member 251 may be configured to drive multiple moving members 252 synchronously along their respective corresponding radial directions to approach the cavity wall of the hollow cavity 20 under the drive of the locking drive assembly 24, so as to drive the moving members 252 to gradually abut against the cavity wall of the hollow cavity 20, thereby achieving braking of the winding wheel 210. With this setting, in the initial state, the winding wheel 210 is in a state where it can rotate normally for easy use. When it is necessary to lock the winding wheel 210, the locking drive assembly 24 can be activated to drive the moving part 252 to gradually abut against the cavity wall of the hollow cavity 20 to achieve braking of the winding wheel 210.

[0032] In some embodiments, the structure of the abutment transmission member 251 is described; please refer to [reference needed]. Figure 7The abutment transmission component 251 may include a threaded shaft 2511 and a slider 2512. The threaded shaft 2511 can be connected to the locking drive assembly 24, and the slider 2512 can be sleeved on the threaded shaft 2511 and threadedly connected to it. In this configuration, the locking drive assembly 24 drives the threaded shaft 2511 to rotate, and the threaded shaft 2511 converts its rotation into axial movement of the slider 2512 through its threaded engagement with the slider 2512. Furthermore, the threaded engagement itself is self-locking, ensuring that the current state is maintained even in unexpected situations.

[0033] In some embodiments, please refer to Figures 5 to 7 The moving part 252 can be disposed between the slider 2512 and the circumferential inner wall of the hollow cavity 20. In this configuration, the moving part 252 can move between the slider 2512 and the circumferential inner wall of the hollow cavity 20, and the moving part 252 can contact or connect with the slider 2512 to convert the axial movement of the slider 2512 into the radial movement of the moving part 252.

[0034] In some embodiments, the manner in which the abutment transmission member 251 controls the radial movement of the moving member 252 is further optimized; please refer to [reference needed]. Figure 5 and Figure 6 One of the moving component 252 and the slider 2512 may be provided with a first guide surface 25211. The first guide surface 25211 may be set at an angle to the axis. The threaded shaft 2511 may be configured to rotate under the drive of the locking drive assembly 24, thereby causing the slider 2512 to move axially along the winding wheel 210. The contact area between the other of the moving component 252 and the slider 2512 and the first guide surface 25211 may move synchronously with the slider 2512, thereby causing the moving component 252 to move closer to and / or away from the cavity wall of the hollow cavity 20. The first guide surface 25211 is set at an angle to the axis, and the slider 2512 and the moving component 252 are in contact with each other through the first guide surface 25211, so as to convert the axial movement of the slider 2512 into the radial movement of the moving component 252. In conjunction with the description of the preceding embodiments, it can be understood that by adopting a guide surface design, the first guide surface 25211 can be used to drive the moving part 252 away from or towards the cavity wall of the hollow cavity 20, and simultaneously the elastic element (refer to the first elastic element 281 or the second elastic element 282 described in the preceding embodiments) can be used to apply the opposite motion guidance to the first guide surface 25211, thereby realizing the control of the moving part 252 to move back and forth in the radial direction.

[0035] In some embodiments, only one slider 2512 may be used in conjunction with multiple moving parts 252, and the number of first guide surfaces 25211 needs to be set according to the number of moving parts 252. In other embodiments, multiple sliders 2512 may be set one-to-one with the number of moving parts 252, and the number of first guide surfaces 25211 also needs to be set according to the number of moving parts 252.

[0036] In other embodiments, the manner in which the abutment transmission member 251 controls the radial movement of the moving member 252 is further optimized; please refer to [reference needed]. Figure 7 and Figure 8 The first guide surface 25211 can be configured to drive the moving member 252 closer to the cavity wall of the hollow cavity 20 when the slider 2512 moves along the first direction of the axis. A second guide surface 25212 can be provided on one of the moving member 252 and the slider 2512. The second guide surface 25212 can be set at an angle to the axis. The contact area between the other of the moving member 252 and the slider 2512 and the second guide surface 25212 can move synchronously with the slider 2512. The second guide surface 25212 can be configured to drive the moving member 252 away from the cavity wall of the hollow cavity 20 when the slider 2512 moves along the second direction of the axis. The first direction and the second direction can be opposite to each other. In these embodiments, the addition of the second guide surface 25212 allows the moving member 252 to move back and forth radially using two guide surfaces. With this configuration, the elastic element can be eliminated, and the moving member 252 can be guided by two guide surfaces instead. It is understood that the first direction and the second direction are two opposite directions along the axis.

[0037] In some embodiments, the first guide surface 25211 and the second guide surface 25212 may both be disposed on the moving member 252 or both on the slider 2512.

[0038] In some embodiments, the design of the first guide surface 25211 and the second guide surface 25212 is further optimized; please refer to [reference needed]. Figures 9 to 12One of the moving component 252 and the slider 2512 may be provided with a motion groove 2521. The motion groove 2521 may include a main groove body 25213 and an opening 25214 radially communicating with the main groove body 25213. The other of the moving component 252 and the slider 2512 may include a guide portion 25121 and a connecting portion 25122. The guide portion 25121 may be provided in the main groove body 25213, and the connecting portion 25122 may be connected to the guide portion 25121 through the opening 25214. The circumferential width of the main groove body 25213 may be greater than the circumferential width of the opening 25214, so that the two radially opposite groove walls of the main groove body 25213 can respectively serve as the first guide surface 25211 and the second guide surface 25212. In these embodiments, the first guide surface 25211 and the second guide surface 25212 are formed in a motion groove 2521 to facilitate processing and facilitate the compact design of the structure. Specifically, the structure of the motion slide 2521 is optimized, and the circumferential width of the main groove 25213 is set to be greater than the circumferential width of the opening 25214, so that the required first guide surface 25211 and second guide surface 25212 can be formed in the main groove 25213.

[0039] For example, please refer to Figure 11 The motion groove 2521 is disposed on the moving part 252, and the slider 2512 includes a guide portion 25121 and a connecting portion 25122. The connecting portion 25122 can be sleeved on the threaded shaft 2511 and connected to the guide portion 25121. At least a portion of the guide portion 25121 can be disposed within the motion groove 2521 and has a structure that contacts and engages with the first guide surface 25211 and the second guide surface 25212. Specifically, the contact engagement between the guide portion 25121 and the first guide surface 25211 and the second guide surface 25212 can be either point contact or surface contact. Of course, the shape of the guide portion 25121 can be adapted to the shape of the motion groove 2521 to ensure that the contact area between the guide portion 25121 and the first guide surface 25211 and the second guide surface 25212 can move synchronously with the slider 2512. Furthermore, the guide portion 25121 and the connecting portion 25122 can be integrally formed or assembled and fixed.

[0040] For another example, please refer to Figure 12The motion groove 2521 is disposed on the slider 2512, and the moving member 252 includes a guide portion 25121 and a connecting portion 25122. The guide portion 25121 may be at least partially disposed within the motion groove 2521 to achieve the engagement as described in the previous example, while the connecting portion 25122 serves as a structure in the moving member 252 for abutting against the cavity wall of the hollow cavity 20. In this configuration, through the engagement of the guide portion 25121 of the moving member 252 with the two guide surfaces in the motion groove 2521, the connecting portion 25122 can abut against or move away from the cavity wall of the hollow cavity 20.

[0041] In some embodiments, please refer to Figure 7 and Figure 8 The locking mechanism 220 may also include a motion limiting member 26, which may be located at the end of the threaded shaft 2511 away from the locking drive assembly 24. Alternatively, the motion limiting member 26 may be sleeved on the end of the threaded shaft 2511 away from the locking drive assembly 24, while the other end of the threaded shaft 2511 may be used to connect to the locking drive assembly 24.

[0042] In some embodiments, please refer to Figure 7 and Figure 8 The projection of the moving part 252 along the axis of the winding wheel 210 can at least partially coincide with the motion limiter 26 and the locking drive assembly 24, respectively. In this configuration, it is ensured that both ends of the moving part 252 can abut against the motion limiter 26 and the locking drive assembly 24, respectively, to achieve limiting.

[0043] In some embodiments, please refer to Figure 7 and Figure 8 The locking drive assembly 24 and the motion limiting member 26 can cooperate to limit the axial travel of the moving member 252 along the winding reel 210. Specifically, the motion limiting member 26, which cooperates with the locking drive assembly 24, restricts the axial movement of the moving member 252 at both ends. In particular, as the slider 2512 moves axially and the moving member 252 moves radially via a guide surface angled to the axis, the guide surface can bear the radial component of the force exerted by the slider 2512, guiding the moving member 252 to move radially. The axial component is borne by the motion limiting member 26 and the locking drive assembly 24, further ensuring that the moving member 252 can move stably radially during contact with the slider 2512. Furthermore, the motion limiting member 26 and the locking drive assembly 24 can also define the axial travel of the slider 2512 to prevent the slider 2512 from disengaging from the threaded connection of the threaded shaft 2511 as it rotates.

[0044] In some embodiments, the structure of the abutment component 25 is further described; please refer to [reference needed]. Figure 1 The abutment component 25 may also include an elastic layer 253. The abutment component 25 can abut against the cavity wall of the hollow cavity 20 by utilizing the elastic layer 253, thereby increasing the friction between the abutment component 25 and the cavity wall, improving the braking effect, and this arrangement helps to buffer the rotating winding wheel 210 during braking, reducing the impact and noise between the abutment component 25 and the winding wheel 210.

[0045] In some embodiments, please refer to Figure 13 and Figure 14 The elastic layer 253 can be disposed to cover the side of the moving part 252 facing the cavity wall of the hollow cavity 20. With this arrangement, the elastic layer 253 can be firmly attached to the contact surface between the moving part 252 and the cavity wall of the hollow cavity 20 by covering, and it can also reduce the impact of the rotation of the winding wheel 210 on the stability of the elastic layer 253 on the moving part 252.

[0046] In other embodiments, please refer to Figure 13 and Figure 14 The moving part 252 has a mounting groove 2522 on the side facing the cavity wall of the hollow cavity 20. The elastic layer 253 can be embedded in the mounting groove 2522, and the thickness of the elastic layer 253 along the radial direction of the winding wheel 210 can be greater than the depth of the mounting groove 2522. With this configuration, the elastic layer 253 can be fixed to the moving part 252 in an embedded manner. Furthermore, by setting the thickness of the elastic layer 253 to be greater than the depth of the mounting groove 2522, it can be ensured that as the moving part 252 approaches the cavity wall of the hollow cavity 20, the elastic layer 253 can contact the cavity wall before the moving part 252 body, thereby increasing friction in a timely manner.

[0047] In some embodiments, the structure of the abutment transmission member 251 is described; please refer to [reference needed]. Figure 13 and Figure 14 One of the radially opposite sides of the moving member 252 and the elastic layer 253 may be provided with multiple protrusions 2523, and the other side may be provided with a groove 2531 corresponding to the protrusions 2523. The groove 2531 can cooperate with the protrusions 2523 to restrict the circumferential sliding between the elastic layer 253 and the moving member 252. Since the rotation of the winding wheel 210 will exert a circumferential sliding force on the elastic layer 253, when the elastic layer 253 is set by embedding, the cooperation between the protrusions 2523 and the groove 2531 can be added to prevent the elastic layer 253 from sliding axially relative to the moving member 252, thereby improving the stability of the elastic layer 253 on the moving member 252.

[0048] In some embodiments, the structure of the abutment transmission member 251 is described; please refer to [reference needed]. Figure 13 and Figure 14 The mounting groove 2522 may include a mounting groove body 25221 and a groove opening 25222 that connects to the mounting groove body 25221 in a radial direction. The circumferential width of the mounting groove body 25221 may be greater than the circumferential width of the groove opening 25222. A portion of the elastic layer 253 may be sandwiched between the two radially opposite groove walls of the mounting groove body 25221, and another portion of the elastic layer 253 may be exposed through the groove opening 25222. Because of the rotation of the winding wheel 210, the embedded elastic layer 253 is easily detached from the mounting groove 2522 under the frictional rotation. Therefore, the structure of the mounting groove 2522 is optimized. By designing the circumferential width of the mounting groove body 25221 to be greater than the circumferential width of the groove opening 25222, a portion of the elastic layer 253 along both sides along the circumferential direction can be clamped between the radially opposite side walls of the mounting groove body 25221, preventing the elastic layer 253 from being detached from the mounting groove 2522 by being driven by the winding wheel 210. This arrangement also further improves the stability of the elastic layer 253 on the moving part 252, enhancing the stability of contact with the cavity wall and frictional performance.

[0049] In some embodiments, the elastic layer 253 may be made of a material such as silicone.

[0050] In some embodiments, the structure of the lock-up drive component 24 is described; please refer to [reference needed]. Figure 8 , Figure 15 and Figure 16 The locking drive assembly 24 may include a drive seat 241, which can abut against the moving member 252, thereby cooperating with the motion limiter 26 to restrict the movement of the moving member 252 in the axial direction.

[0051] In some embodiments, the drive housing 241 may be provided with a component mounting cavity 2411, and the locking drive assembly 24 may further include a shaft drive motor 242. The shaft drive motor 242 may be disposed within the component mounting cavity 2411, and one end of the shaft drive motor 242 may be connected to a threaded shaft 2511 to drive the threaded shaft 2511 to rotate. Based on this, the drive housing 241 can not only be used to limit the axial movement of the moving part 252, but also to accommodate the shaft drive motor 242.

[0052] In some embodiments, please refer to Figure 7 and Figure 8A gap region 2413 can be formed along the axis between the drive seat 241 and the moving member 252. The locking drive assembly 24 may also include a detection element 244, which can be disposed on the drive seat 241 and located within the gap region 2413. The detection element 244 is configured to generate a detection signal for the radial movement of the moving member 252. The required gap region 2413 can be formed by utilizing the design of the contact position between the drive seat 241 and the moving member 252. The gap region 2413 can accommodate the detection element 244 to ensure that the detection element 244 can detect the radial movement of the moving member 252.

[0053] In some embodiments, the moving member 252 has a first position and a second position relative to the cavity wall of the hollow cavity 20. In the first position, the moving member 252 abuts against the cavity wall of the hollow cavity 20, and the winding wheel 210 is in a locked state. In the second position, the moving member 252 is spaced from the cavity wall of the hollow cavity 20, and the winding wheel 210 is in a rotatable state. Based on this, the detection member 244 can be configured to generate a detection signal when the moving member 252 reaches the first position, or it can be configured to generate a detection signal when the moving member 252 reaches the second position.

[0054] In some embodiments, the detection element 244 can generate a detection signal by contacting the moving element 252; for example, the detection element 244 can be a limit switch or a travel switch. In other embodiments, the detection element 244 can utilize the principle of a Hall sensor, employing an inductive sensor, and using the moving element 252 (with a metal structure) for detection. In still other embodiments, the detection element 244 can also employ a photoelectric sensor or a laser displacement sensor for detection.

[0055] In some embodiments, please refer to Figure 7 and Figure 8 The locking drive assembly 24 may include a detection circuit board 243 and a transmission circuit board 245. The detection circuit board 243 may be located at one end of the drive housing 241 away from the abutment assembly 25. One end of the transmission circuit board 245 may be electrically connected to the detection element 244, and the other end of the transmission circuit board 245 may pass through the mounting cavity and be electrically connected to the detection circuit board 243. In this configuration, the signal generated by the detection element 244 can be transmitted through the transmission circuit board 245, via the interior of the drive housing 241, to the detection circuit board 243 outside the drive housing 241. The transmission circuit board 245 is housed within the mounting cavity of the drive housing 241, and the wiring path is structurally protected and not exposed to the outside, thereby improving the reliability of signal transmission.

[0056] In some embodiments, the design of the mounting cavity is described; please refer to [reference needed]. Figure 8 and Figure 16The mounting cavity 2411 may include a first cavity 24111 and a second cavity 24112 that are interconnected. The motor body of the shaft drive motor 242 may be located in the first cavity 24111, and the output shaft of the shaft drive motor 242 may be located in the second cavity 24112. The first cavity 24111 is farther away from the hollow cavity 20 than the second cavity 24112. The mounting cavity inside the lock-up drive assembly 24 is divided into two functional areas, placing the motor body (which does not require mechanical movement) and the output shaft (which requires mechanical movement) in different areas. The first cavity 24111 is farther away from the hollow cavity 20 than the second cavity 24112 to facilitate direct connection between the output shaft and the threaded shaft 2511.

[0057] In some embodiments, please refer to Figure 8 and Figure 16 The drive housing 241 may also be provided with a connecting channel 24113. The connecting channel 24113 can be isolated from the second cavity 24112 and can connect the interval area 2413 and the first cavity 24111. The transmission circuit board 245 can extend to the first cavity 24111 via the connecting channel 24113. In this configuration, the connecting channel 24113, which is independent of the second cavity 24112, is added to physically isolate the transmission circuit board 245 from the output shaft of the shaft drive motor 242, thereby reducing the impact of the operation of the shaft drive motor 242 on the stability of the transmission circuit board 245.

[0058] In some embodiments, the connection between the detection circuit board 243 and the transmission circuit board 245 is described; please refer to [reference needed]. Figure 8 , Figure 15 and Figure 16 A support portion 2412 may protrude from the side end face of the drive base 241 opposite to the hollow cavity 20. A detection circuit board 243 may be disposed on the support portion 2412 and may be spaced apart from the end face along the axis. The detection circuit board 243 can be mounted on one side end face of the drive base 241 by assembling and fixing it with the support portion 2412. The support portion 2412 allows the detection circuit board 243 to be spaced apart from the end face of the drive base 241, creating a usable gap between the detection circuit board 243 and the end face. This gap provides space for the routing of the transmission circuit board 245. With this configuration, the transmission circuit board 245 can pass through this gap without requiring additional routing grooves or through holes in the drive base 241.

[0059] In some embodiments, please refer to Figure 16The transmission circuit board 245 can extend to the side of the transmission circuit board 245 opposite to the drive housing 241 via the gap between the detection circuit board 243 and the end face. In this configuration, it is convenient to electrically connect the transmission circuit board 245 to the side of the detection circuit board 243 opposite to the drive housing 241, so that the detection circuit board 243 can integrate components and wiring on that side.

[0060] In some embodiments, the structure of the abutment transmission member 251 is described; please refer to [reference needed]. Figure 4 The locking mechanism 220 may also include a plurality of motion guides 27, which may be spaced apart axially. In this configuration, a space for accommodating and restricting the axial movement of the moving member 252 can be formed between adjacent motion guides 27, thereby avoiding interference between adjacent moving members 252.

[0061] In some embodiments, please refer to Figure 4 , Figures 9 to 13 Multiple motion guides 27 can be used to radially limit the slider 2512 and guide its axial movement. With this configuration, the motion guides 27 can reduce radial offset or wobbling of the slider 2512 and guide its axial movement, thereby improving the stability of the engagement between the threaded shaft 2511 and the slider 2512, and enhancing the stability of the slider 2512's axial movement.

[0062] In some embodiments, please refer to Figures 9 to 13 Each moving part 252 can be embedded between two adjacent moving guides 27 along its corresponding radial direction. In this configuration, during radial movement, the circumferential position of the moving part 252 is constrained by the guides to prevent the moving part 252 from rotating or swaying around the axis, ensuring that the moving part 252 always moves in the predetermined radial direction and ensuring the accuracy of its position when abutting the cavity wall.

[0063] In some embodiments, the motion guide 27 may be an independently provided structural component, the end of which can be assembled and fixed with the motion limiting member 26 and / or the drive seat 241.

[0064] In some embodiments, the motion guide 27 may also be integrally formed with the motion limiter 26 or the drive seat 241.

[0065] In some embodiments, please refer to Figure 4The motion guide 27 may include a first sub-guide 271 and a second sub-guide 272 arranged along the axial direction. The first sub-guide 271 may be integrally formed with one of the motion limiting member 26 or the drive seat 241, and the second sub-guide 272 may be integrally formed with the other of the motion limiting member 26 or the drive seat 241. The first sub-guide 271 and the second sub-guide 272 may be assembled and fixed by means of plugging or other methods.

The spool motor is connected to the winding wheel 210 to drive the winding wheel 210 to rotate. The winding wheel 210 is provided with a hollow cavity 20, and the locking mechanism 220 is partially disposed in the hollow cavity 20. The locking mechanism 220 is used to restrict the rotation of the winding wheel 210 inside the winding wheel 210.

[0067] For further information on the applications of the winding device 2000, please refer to [link / reference needed]. Figure 17 and Figure 18 This application also provides a fitness device 10000 for winding a cable 4000. The fitness device 10000 includes a cable box body 1000 and a winding reel 210. The cable box body 1000 serves as the outer shell of the fitness device 10000, housing components such as the winding reel 210, and can also house a winding motor. The winding reel 210 is used to wind the cable 4000. The winding reel 210 can be driven by the winding motor to rotate, thereby winding the cable 4000, providing convenience for the user to wind the cable 4000 during operation. Furthermore, the winding reel 210 is also used in its natural state to assist the user in pulling out the cable 4000. Additionally, the winding reel 210 can also be driven to rotate to assist the user in pulling out the cable 4000.

[0068] Please refer to Figures 17 to 18 The fitness equipment 10000 also includes a cable routing device 3000, which is located inside the cable box body 1000 and winds the cable 4000. The cable routing device 3000 is fixed to the cable outlet side 1100 of the cable box body 1000 by assembly. The cable routing device 3000 can influence the winding of the cable 4000 on the winding reel 210, so that the cable 4000 is wound regularly from one end of the winding reel 210 to the other end, improving the tightness and uniformity of the cable 4000 winding.
