Description

[0001] This application is a divisional application of Chinese patent application filed on February 21, 2023, with application number 202310180437.7 and invention title "Wire Winding Mechanism and Output Device". Technical Field

[0002] This application relates to the field of power output equipment technology, and in particular to a wire winding mechanism and power output equipment. Background Technology

[0003] Rope-based power output devices are a widely used type of power output device. These devices typically apply resistance or power to the rope, and users exercise by pulling the rope back and forth or being pulled by the rope.

[0004] Some cable-type power output devices use winding wheels as cable storage devices. By applying resistance or power to the rotation of the winding wheel, the cable is controlled. When the cable is pulled and retracted, the winding wheel will rotate in the corresponding direction. However, when the cable is retracted, the winding of the cable on the winding wheel is not regular. Since cable-type power output devices continuously reciprocate the feeding and unloading of the cable during operation, the cable is very easy to get tangled together when winding and unwinding on the winding wheel, resulting in cable jamming and affecting subsequent use. Summary of the Invention

[0005] This application provides a wire winding mechanism and a power output device.

[0006] The cable winding mechanism of this application includes: a base frame with a cable outlet; a winding wheel rotatably mounted on the base frame for winding a cable; and a cable winding mechanism configured to oscillate under the action of a linkage mechanism or a power mechanism. The cable winding mechanism includes a swing seat, a guide arm, and a guide mechanism. The swing seat is rotatably mounted on the base frame around the cable outlet. The guide arm is connected to the swing seat, and the guide mechanism is mounted on the guide arm. The cable passes through the guide mechanism and exits from the cable outlet. The guide mechanism is configured to move synchronously with the cable's release or retraction position on the winding wheel. In some embodiments, the guide arm is connected to the outer periphery of the swing seat and extends radially outward along the swing seat.

[0007] In some embodiments, the guide arm includes a first guide arm and a second guide arm arranged side by side. The guiding mechanism includes a guide wheel disposed between the first guide arm and the second guide arm.

[0008] In some embodiments, the guiding mechanism further includes a restraining frame disposed at one end of the guide arm away from the swing seat. The restraining frame is configured to restrain the cable onto the guide reel.

[0009] In some embodiments, the guide wheel includes a pair of guide wheels, each of which has a groove along its circumference, and the cable passes through the groove at the point where the two guide wheels are tangent.

[0010] In some embodiments, the cable winding mechanism further includes an angle detection device for detecting the swing angle of the cable winding mechanism.

[0011] In some embodiments, the angle detection device includes: a Hall sensor disposed on a base; a magnetic ring concentrically disposed on the swing seat; or a magnetic element disposed on the guide arm.

[0012] In some embodiments, the linkage mechanism includes: a worm gear, which is connected to the winding wheel; and a self-locking worm wheel, which is concentrically disposed on the swing seat and meshes with the worm gear.

[0013] In some embodiments, the linkage mechanism is used to drive the threading port of the cable laying mechanism to swing by one cable diameter when the winding wheel rotates one revolution.

[0014] In some embodiments, when the winding wheel rotates in the same direction, the linkage mechanism is configured to drive the cable laying mechanism to swing from one end of the winding wheel to the other end. Alternatively, when the winding wheel rotates in the same direction, the linkage mechanism is configured to drive the cable laying mechanism to reciprocate between one end of the winding wheel and the other end of the winding wheel.

[0015] In some embodiments, the base frame is further provided with a limiting structure, which is used to limit the extreme positions of the wiring mechanism.

[0016] In some embodiments, a micro switch is provided on the limiting structure, and the micro switch is triggered when the wiring mechanism moves to the limit position.

[0017] In some embodiments, the cable winding mechanism further includes a motion detection device for detecting the current movement position of the cable winding mechanism.

[0018] In some embodiments, the motion detection device includes a magnetic ring concentrically disposed on the swing base. Alternatively, the motion detection device includes a magnetic element disposed on the guide arm.

[0019] The power output device in the embodiments of this application includes: The wire winding mechanism as described in any of the preceding embodiments; A power source, which is used to apply power or resistance to the winding reel; A cable, the cable being wound on the winding reel, the end of the cable passing through the cable laying mechanism and exiting through the outlet.

[0020] In some embodiments, by setting a linkage mechanism and a wire laying mechanism, the orderly laying and releasing of the cable on the winding wheel can be automatically achieved by utilizing the rotation of the winding wheel when the winding wheel is unwinding. At the same time, the wire outlet set at the fixed position of the base frame can ensure that the wire leaving the winding wheel is not affected by the wire laying mechanism.

[0021] In some embodiments, by setting a power mechanism and a wire laying mechanism, the power mechanism can drive the wire laying mechanism to move when the winding wheel is opening and laying the wire, thereby realizing the orderly laying and unlaying of the rope on the winding wheel. At the same time, the wire outlet set at the fixed position of the base frame can ensure that the wire leaving the winding wheel is not affected by the wire laying mechanism, or can make irregular ropes orderly wound up at the fixed position and neatly arranged on the winding wheel.

[0022] In some embodiments, during operation, the user pulls the cable back and forth through the cable outlet or is pulled by the cable. When the cable is pulled out of the winding reel, the cable laying mechanism moves synchronously with the position of the cable on the winding reel, achieving orderly cable opening and ensuring smooth, jam-free opening. When the motor drives the winding reel to retract the cable, the cable retracts from the cable outlet, and the cable laying mechanism moves synchronously to achieve orderly cable laying. By setting a linkage mechanism and a cable laying mechanism, or setting a power mechanism and a cable laying mechanism, the orderly laying and unlaying of the cable on the winding reel can be automatically achieved by utilizing the rotation of the winding reel when the cable is being laid. At the same time, the cable outlet located at a fixed position on the base frame ensures that the cable leaving the winding reel is not affected by the cable laying mechanism.

[0030] The following disclosure provides many different implementations or examples for carrying out different structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or reference letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various implementations and / or arrangements discussed.

[0031] Please refer to Figure 1-10 This application discloses a cable winding mechanism, including a base frame 100, a winding wheel 200, a cable winding mechanism 300, and a linkage mechanism 500. The winding wheel 200 is rotatably mounted on the base frame 100, and the cable winding mechanism 300 is movably mounted on the base frame 100. The linkage mechanism 500 connects the winding wheel 200 and the cable winding mechanism 300 and links them together. In use, the cable 800 is wound on the winding wheel 200, with one end fixed to the winding wheel 200 and the other end passing through the cable winding mechanism 300 and exiting the base frame 100 through the cable outlet 700.

[0032] During operation, taking the unwinding of the rope as an example, pulling the rope 800 simultaneously causes the winding wheel 200 to rotate and unwind the rope. The rotation of the winding wheel 200 drives the wire laying mechanism 300 via the linkage mechanism 500. The wire laying mechanism 300 moves synchronously with the unwinding position of the rope 800 on the winding wheel 200. For example, if the rope 800 on the winding wheel 200 is wound from left to right, the unwinding position of the rope 800 is from right to left, and the wire laying mechanism 300 moves synchronously from right to left. That is, the movement direction of the wire laying mechanism 300 is consistent with the unwinding direction of the rope 800 on the winding wheel 200, so that the rope 800 on the winding wheel 200 can be guided by the wire laying mechanism 300, thereby achieving orderly unwinding. After unwinding, the rope 800 passes through the outlet 700 and exits the base frame 100, maintaining a stable outlet position. The winding mechanism then retracts the rope. For example, the rotation of the winding wheel 200 drives the cable 800 to retract. At the same time, the winding wheel 200 drives the cable laying mechanism 300 to move through the linkage mechanism 500. At this time, the cable laying mechanism 300 and the cable 800 move synchronously on the winding wheel 200. For example, if the cable 800 on the winding wheel 200 is wound from the left to the right, the cable laying position of the cable 800 is from left to right. The cable laying mechanism 300 moves synchronously from left to right. That is, the movement direction of the cable laying mechanism 300 is consistent with the cable laying direction of the cable 800 on the winding wheel 200, so that the cable 800 retracted from the outlet 700 can be guided by the cable laying mechanism 300, thereby achieving orderly cable laying. After cable laying, the cable 800 is stably laid on the winding wheel 200, and the cable 800 that has not been laid is retracted sequentially at the fixed position outlet 700.

[0033] By setting up the linkage mechanism 500 and the cable laying mechanism 300, the orderly laying and unlaying of the cable 800 on the winding wheel 200 can be automatically achieved by the rotation of the winding wheel 200 when the winding wheel 200 is unwound. At the same time, the cable outlet 700 set at the fixed position of the base frame 100 can ensure that the line leaving the winding wheel 200, i.e. the cable 800, is not affected by the cable laying mechanism 300.

[0034] In some implementations, such as Figure 10As shown, this application also discloses a cable winding mechanism, including a base frame 100, a winding wheel 200, a cable winding mechanism 300, and a power mechanism 600. The winding wheel 200 is rotatably mounted on the base frame 100, the cable winding mechanism 300 is movably mounted on the base frame 100, and the power mechanism 600 is used to drive the cable winding mechanism 300 to move. In use, the cable 800 is wound on the winding wheel 200, one end is fixed on the winding wheel 200, and the other end passes through the cable winding mechanism 300 and exits the base frame 100 from the cable outlet 700.

[0035] During operation, when the winding wheel 200 unwinds or rewinds the cable, the power mechanism 600 drives the cable laying mechanism 300 to move in the same direction. For example, when the cable 800 is unwinding from the left to the right, the unwinding direction of the winding wheel 200 is from right to left. At this time, the power mechanism 600 drives the cable laying mechanism 300 to move from right to left, thereby guiding the cable 800 at the unwinding point so that the cable 800 can smoothly pass through the outlet 700. For example, when the cable 800 is unwinding from the left to the right, the cable laying direction of the winding wheel 200 is from left to right. At this time, the power mechanism 600 drives the cable laying mechanism 300 to move from left to right, ensuring that the cable 800 can be laid without overlapping and preventing the cable 800 from getting tangled and knotted on the winding wheel 200.

[0036] By setting up a power mechanism 600 and a cable laying mechanism 300, the power mechanism 600 can drive the cable laying mechanism 300 to move when the winding wheel 200 is opening and laying the cable, thereby realizing the orderly laying and unlaying of the cable 800 on the winding wheel 200. At the same time, the cable outlet 700 set at a fixed position on the base frame 100 can ensure that the cable leaving the winding wheel 200 is not affected by the cable laying mechanism 300, or can make the irregular cable 800 be orderly wound up at a fixed position and neatly arranged on the winding wheel 200.

[0037] In this application, the concept of base frame 100 simply refers to providing installation and positioning for winding wheel 200, cable laying mechanism 300, linkage mechanism 500, power mechanism 600, and cable outlet 700. Base frame 100 can be a single component or a combination of multiple mutually fixed components. The movement of cable laying mechanism 300 in this application can be translation or oscillation, and this application does not impose any restrictions. Linkage mechanism 500 can be a gear transmission via a gear set, a belt drive or chain drive, a worm gear 530 drive, a crank-slider mechanism, or a crank-rocker mechanism. The transmission mechanism 600 can be a motor, an electric actuator, or another hydraulic or pneumatic mechanical motion power source 900, etc. It can also include a transmission mechanism that can transmit the power source 900 to the wiring mechanism 300. Any power source 900 or a combination of power source 900 and transmission mechanism that can transmit power to the wiring mechanism 300 is included.

[0038] In some implementations, such as Figure 1-5 As shown, the cable laying mechanism 300 is oscillatingly mounted on the base frame 100, and the oscillation center of the cable laying mechanism 300 is the outlet 700. Since the cable laying mechanism 300 oscillates around the outlet 700, the distance between the cable 800 at the exit position of the cable laying mechanism 300 and the outlet 700 remains constant. That is, the cable laying mechanism 300 oscillates to any position without affecting the transmission of this section of cable 800, thus improving the stability of the cable laying mechanism 300.

[0039] In some embodiments, the cable laying mechanism 300 includes an interconnected swing seat 311 and a guide arm 312. The swing seat 311 is rotatably mounted on the base frame 100 around the cable outlet 700, and the guide arm 312 is used for the cable 800 to pass through. An angle detection device is also provided to detect the swing angle of the cable laying mechanism 300. The swing angle of the cable laying mechanism 300 can be calculated by the angle detection device 313. Since the transmission ratio of the linkage mechanism 500 is known in advance and the diameter of the winding wheel 200 is also known, the number of rotations of the winding wheel 200 can be known by calculating the swing angle, thereby knowing the working status of opening and retracting the cable, such as the working progress of opening or retracting the cable, or the length of the cable 800 that has been retracted or released.

[0040] In some implementations, such as Figure 4 As shown, the angle detection device 313 may include a magnetic ring 314 disposed on the swing seat 311. That is, when the swing seat 311 rotates, the Hall sensor 316 fixed on the base frame 100 can detect the change in magnetic field strength, and the swing angle of the swing seat 311 can be determined based on the magnitude of the magnetic field strength; as shown Figure 5As shown, the angle detection device 313 can also be a magnetic component 315 mounted on the guide arm 312 and a Hall sensor 316 mounted on the base frame 100. When the guide arm 312 rotates with the swing seat 311, the Hall sensor 316 fixed on the base frame 100 can also sense the change in magnetic field strength. The swing angle of the swing seat 311 and the guide arm 312 can be known based on the magnitude of the magnetic field strength.

[0041] In some implementations, such as Figure 2-3 As shown, the linkage mechanism 500 includes a self-locking worm gear 510 and a worm 530. The winding wheel 200 drives the worm 530 on the swing seat 311 to rotate through the worm 530. By utilizing the self-locking effect of the self-locking worm gear 510 and the worm 530, unidirectional transmission of the worm 530 to the worm gear can be achieved, while the worm gear self-locks the worm 530. This can prevent the swing seat 311 from rotating erroneously due to gravity, impact or other reasons, which would cause the winding wheel 200 to rotate and thus break the wire.

[0042] The self-locking worm gear 510 can be a complete full-circumference worm gear or an incomplete partial worm gear, as long as the tooth arrangement of the worm gear meets the oscillation stroke.

[0043] In some implementations, such as Figure 6-8 As shown, the wire laying mechanism 300 is slidably mounted on the base frame 100 and its sliding direction is parallel to the axis of the winding wheel 200. When the winding wheel 200 opens or retracts the wire, the movement of the opening position and the laying position is parallel to the axis of the winding wheel 200. By using the wire laying mechanism 300, which is also arranged in the same direction, the opening position, the laying position and the wire laying mechanism 300 can remain relatively stationary when opening or retracting the wire, which further improves stability.

[0044] In some implementations, such as Figure 7 As shown, the cable laying mechanism 300 includes a sliding seat 321 slidably mounted on the base frame 100, and a wire guide mechanism 324 mounted on the sliding seat 321 for the cable 800 to pass through. An optical axis 322 is provided on the base frame 100 in a direction parallel to the axial direction of the winding wheel 200. Figure 7 As shown, in some embodiments, the wiring mechanism 300 further includes a linear bearing 323 disposed on the sliding seat 321. The linear bearing 323 can be sleeved on the optical shaft 322 and can slide on the optical shaft 322. The sliding seat 321 slides on the optical shaft 322 via the linear bearing 323. The arrangement of the optical shaft 322 and the linear bearing 323 reduces the sliding resistance of the sliding seat 321 and improves the sliding accuracy of the sliding seat 321. Simultaneously, the optical shaft 322 and the linear bearing 323 also provide stable support for the sliding seat 321. In some embodiments, there are at least two optical shafts 322 and at least two sliding seats 321, and the two sets of optical shafts 322 can fully provide stable support for the base frame 100. Accordingly, as... Figure 7 As shown, the number of linear bearings 323 can also be at least two.

[0045] In some embodiments, the linkage mechanism 500 includes a worm 530 and a self-locking worm nut 520. The worm 530 is connected to the winding wheel 200 for transmission. The self-locking worm nut 520 is disposed on the sliding seat 321. The rotation of the winding wheel 200 drives the worm 530 to rotate, thereby driving the self-locking worm nut 520 and the sliding seat 321 to translate along the worm 530. The self-locking worm nut 520 can also realize unidirectional transmission from the worm 530 to the self-locking worm nut 520, and at the same time realize the self-locking of the worm nut 520 to the worm 530. This can prevent the sliding seat 321 from rotating erroneously due to gravity, impact or other reasons, thereby causing the winding wheel 200 to rotate and the wire to come apart.

[0046] In some embodiments, such as Figure 8 As shown, the conductor mechanism 324 includes a cable tray 325 disposed on a sliding seat 321, a rotating seat 326 located behind the cable tray 325 and rotatably disposed on the sliding seat 321 about the cable outlet direction of the cable tray 325, wherein the rotating seat 326 has a cable passage along the axis of rotation, and a reversing port 327 disposed on the rotating seat 326 and communicating with the cable passage, the reversing port 327 being tangent to the axis of rotation of the rotating seat 326, the cable 800 passing through the cable tray 325, the cable passage and the reversing port 327 in sequence, and finally exiting from the outlet 700.

[0047] The cable tray 325 is set on the sliding seat 321 relative to the winding wheel 200. The cable tray 325 includes the inlet direction from the winding wheel 200 and the outlet direction from the cable tray 325 into the cable passage of the rotating seat 326.

[0048] During operation, as the sliding seat 321 slides along the optical axis 322, the positions of the wire guide mechanism 324 and the outlet 700 will inevitably change, resulting in changes in their relative distance and relative angle. In this embodiment, a rotating seat 326 is provided, and the tension on the cable 800 is used to enable the rotating seat 326 to adaptively adjust its angle as the relative positions of the wire guide mechanism 324 and the outlet 700 change, so that the reversing port 327 of the rotating seat 326 is always aligned with the outlet 700, thereby preventing wire skipping caused by excessive changes in the relative positions of the wire guide mechanism 324 and the outlet 700.

[0049] In some embodiments, the wire guide mechanism 324 may also have a first deflector wheel 328 provided at the cable outlet 325, the first deflector wheel 328 being tangent to the rotation axis of the rotating seat 326; in some embodiments, the wire guide mechanism 324 may also have a second deflector wheel 329 provided at the deflector outlet 327, the second deflector wheel 329 being tangent to the rotation axis of the rotating seat 326, that is, by providing the first deflector wheel 328 and the second deflector wheel 329, the sliding of the cable 800 relative to the wire guide mechanism 324 is converted into rolling, reducing frictional resistance and wear.

[0050] In some embodiments, such as Figures 1-3 as well as Figures 7-8 As shown, a cable exit wheel 710 is provided at the cable exit 700, which can reduce the wear of the cable 800 as it passes through the cable exit 700. In some embodiments, the cable exit wheels 710 are a pair of wheels, and at least one of the cable exit wheels 710 is provided with rotational damping. By providing rotational damping, the cable 800 can have a certain tension when opening or retracting the cable, so that the cable 800 is taut. The rotational damping provided in the cable exit wheel 710 can be a direct setting of rotational damping for the rotation of the cable exit wheel 710.

[0051] In some embodiments, the transmission ratio of the linkage mechanism 500 can be reasonably set so that when the winding wheel 200 rotates once, the linkage mechanism 500 drives the threading opening of the wire laying mechanism 300 to translate or swing by a cable diameter of 800, which further improves the accuracy of wire laying and opening.

[0052] In some embodiments, when the winding wheel 200 rotates in the same direction, the linkage mechanism 500 drives the cable laying mechanism 300 to swing or slide from one end of the winding wheel 200 to the other end, thereby realizing the orderly opening or winding of the cable 800 from one end of the winding wheel 200 to the other end. In some embodiments, as the length of the cable 800 increases, it is necessary to make full use of the winding wheel 200 to lay multiple layers of cable. At this time, when the winding wheel 200 rotates in the same direction, the linkage mechanism 500 drives the cable laying mechanism 300 to swing or slide back and forth between the two ends of the winding wheel 200, thereby realizing that in each layer of cable laying, the cable laying mechanism 300 can be used to open or wind up the cable from one end of the winding wheel 200 to the other end in a limited manner. The linkage mechanism 500 can be any transmission mechanism in the prior art that can realize reciprocating motion (e.g., cylindrical cam, end face cam, crank-slider mechanism).

[0053] In some embodiments, such as Figure 3As shown, a limit structure 101 is also provided on the base frame 100. The limit structure 101 is used to limit the extreme position of the cable laying mechanism 300. By limiting the extreme position of the cable laying mechanism 300 through the limit structure 101, it is prevented that the cable laying mechanism 300 will cause the cable 800 to be incorrectly laid after exceeding the extreme position. In some embodiments, a micro switch 102 is also provided on the limit structure 101. When the cable laying mechanism 300 moves to the extreme position, the micro switch 102 is triggered. The micro switch 102 can emit an electrical signal. The electrical signal indicates that the cable laying mechanism 300 has moved to the limit structure 101. The electrical signal can be used to give an early warning of the extreme position of the cable laying mechanism 300 or to take corresponding actions, such as stopping the cable laying.

[0054] In some embodiments, such as Figure 1-5 As shown, the cable laying mechanism 300 includes a guiding mechanism 400 for the cable 800 to pass through. The guiding mechanism 400 guides the cable 800. A guide wheel 410 can be used in the guiding mechanism 400 to reduce friction and wear of the cable 800 as it passes through. In some embodiments, the guiding mechanism 400, in addition to the guide wheel 410, also includes a limiting frame 420. The limiting frame 420 can be a larger frame or a smaller frame conforming to the shape of the cable 800. The limiting frame 420 is used to restrain the cable 800 on the guide wheel 410, preventing the cable 800 from contacting other structures besides the guide wheel 410. In some embodiments, such as... Figure 5 As shown, the guide mechanism 400 includes a pair of guide wheels 430, and each pair of guide wheels 430 is provided with a groove. At this time, the cable 800 passes through the groove at the tangent point of the two guide wheels 430. The position of the cable 800 can be restricted by the space formed by the two grooves at the tangent point, so as to prevent the cable 800 from rubbing against other structures.

[0055] In some embodiments, the wire winding mechanism further includes a motion detection device, which is used to detect the current movement position of the wire winding mechanism 300. By detecting the current movement position of the wire winding mechanism 300 and combining it with parameters such as the transmission ratio of the linkage mechanism 500, the diameter of the winding wheel 200, and the diameter of the cable 800, the number of turns of the winding wheel 200 during wire unwinding or wire winding, the length of the cable 800 during wire unwinding, the length of the cable 800 during wire winding, and the position of the cable 800 on the winding wheel 200 can be deduced.

[0056] For example, when the wiring mechanism 300 swings, the motion detection device may be the magnetic ring 314 or the magnetic element 315 in the aforementioned embodiments; when the wiring mechanism 300 slides, the motion detection device may include the magnetic element 315 disposed on the sliding seat 321 and the Hall sensor 316 disposed on the base frame 100. The Hall sensor 316 detects the magnetic field strength of the magnetic element 315, thereby knowing the motion state of the sliding seat 321 and the wiring mechanism 300.

[0057] Please refer to Figure 9 and Figure 10 This application discloses a power output device 1000, which includes any of the wire winding mechanisms in the foregoing embodiments, and also includes a power source 900 for applying power or resistance to the winding wheel 200, and a cable 800 wound on the winding wheel 200 with its end passing through the wire winding mechanism 300 and through the outlet 700.

[0058] During operation, the user pulls the cable 800 back and forth through the outlet 700 or is pulled by the cable 800. When the cable 800 is pulled out from the winding wheel 200, the cable laying mechanism 300 can move synchronously with the position of the cable 800 on the winding wheel 200 to achieve orderly cable opening and ensure smooth and uninterrupted cable opening. When the motor drives the winding wheel 200 to retract the cable 800, the cable 800 is retracted from the outlet 700, and the cable laying mechanism 300 moves synchronously to achieve orderly cable laying. By setting a linkage mechanism 500 and a cable laying mechanism 300 or setting a power mechanism 600 and a cable laying mechanism 300, the orderly laying and unlaying of the cable 800 on the winding wheel 200 can be automatically achieved by the rotation of the winding wheel 200 when the winding wheel 200 is opening. At the same time, the outlet 700 set at a fixed position on the base frame 100 can ensure that the cable leaving the winding wheel 200 is not affected by the cable laying mechanism 300.
