Detailed ways

In the following description, numerous details are provided in order to provide a thorough understanding of the invention. It will be appreciated, however, to those skilled in the art that the following description is merely illustrative of preferred embodiments of the invention, and that the invention may be practiced without one or more of these details. In addition, in order to avoid confusion with the present invention, some technical features known in the art are not described in detail.

Embodiments of the present invention provide a rope winding device. The roping device can provide a better source of load resistance for fitness. Of course, the rope winding device can also be applied to other scenarios requiring load resistance sources such as rehabilitation training.

For clarity and simplicity of description, the radial direction X-X and the axial direction Y-Y of the roping device are defined. The radial direction X-X and the axial direction Y-Y may be perpendicular to each other. It can be understood that the radial direction X-X can be any direction in the radial plane of the rope winding device, not just the direction shown in the figure.

The roping device may be generally flat. That is, the dimension of the roping device in the axial direction Y-Y is smaller, and may be smaller than its dimension in the radial direction X-X. The rope winding device may include a main body, a rope winder, a rope body and a permanent magnet synchronous motor. The main body may take any suitable configuration, including but not limited to a housing or a central shaft (described in more detail below). The rope winding device provided by the embodiments of the present invention will be described in detail below in conjunction with specific embodiments.

In a first exemplary embodiment, the main body may include a housing 100 as shown in FIGS. 1-3 . One end of the rope body 400 can be connected to the rope winder 300 by any suitable means such as welding, bonding or clamping. The other end of the rope body 400 can protrude out of the rope wrapping device. In practical applications, the other end of the rope body 400 may be connected to an operating device such as a pull rod. The rope body 400 may adopt various types of rope bodies known in the art or that may appear in the future, including but not limited to steel wire ropes or nylon ropes.

The rope winder 300 can be used to wind the rope body 400 . Exemplarily, the rope winder 300 can rotate in one direction (for example, clockwise) to wind the rope body 400 on the rope winder 300 . In this way, the rope body 400 can be collected on the rope wrapping device. The rope winder 300 can rotate in a direction opposite to one direction (for example, counterclockwise), so as to unwind the rope body 400 from the rope winder 300 , so that the rope body 400 can be released.

The permanent magnet synchronous motor provides excitation with permanent magnets, which makes the motor structure relatively simple, reduces processing and assembly costs, and saves the collector ring and brush that are prone to problems, improving the reliability of the motor operation; and because no excitation is required current, without excitation losses, increasing the efficiency and power density of the motor. The permanent magnet synchronous motor 500 may include a stator 510 and a rotor 520 . The stator 510 may generate a rotating magnetic field. The rotor 520 can be made of permanent magnet material. The rotor 520 can rotate in the axial direction Y-Y within the rotating magnetic field. Exemplarily, the side of the rotor 520 facing the stator 510 may be provided with a magnetic steel 540 . Magnetic steel 540 has many advantages such as stable performance, easy processing and mature technology. By setting the magnetic steel 540, the performance of the permanent magnet synchronous motor 500 is more stable and the service life is longer.

In this embodiment, the stator 510 may surround the rotor 520 . The stator 510 is located on the outer side of the rotor 520 along the radial direction X-X. The rotor 520 can rotate within the stator 510 about the axial direction Y-Y. The stator 510 can be connected to the main body (namely the housing 100 ) by any suitable means such as welding, bonding or clamping. The rotor 520 may be coaxially connected to the roping winder 300 . In this embodiment, the rotor 520 and the rope winder 300 may be distributed along the axial direction Y-Y of the rope winding device. Through the rotation of the rotor 520 , the rope winder 300 can be driven to rotate, so as to realize the retraction and release of the rope body 400 . That is to say, the permanent magnet synchronous motor 500 provides power for retracting and unwinding the rope body 400 . Therefore, by arranging the permanent magnet synchronous motor 500, both retracting and retracting of the rope body 400 can be powered. This power creates load resistance when the user wants to prevent the cord 400 from wrapping around the cord winder 300 .

In this embodiment, the stator 510 , the rotor 520 and the rope winder 300 can all be arranged inside the housing 100 . Thus, the exterior of the housing 100 is the exterior of the roping device. In order to make the other end of the rope body 400 protrude out of the rope winding device, a rope hole 110 may be provided on the casing 100 . The rope hole 110 may communicate the exterior and interior of the housing 100 . The other end of the rope body 400 can extend out of the casing 100 through the rope hole 110 . Exemplarily, the rope holes 110 and the rope winders 300 may be distributed along the radial direction X-X of the rope winder. That is, the rope hole 110 and the rope winder 300 may be located in the same plane. In this way, the rope body 400 can be retracted more smoothly, thereby reducing the energy consumption of the permanent magnet synchronous motor 500, so that the rope winding device can be more energy-saving.

The shell 100 can play a protective role, preventing the permanent magnet synchronous motor 500, the rope winder 300 and the rope body 400 wound on the rope winder 300 from being damaged by external force. Moreover, through reasonable arrangement, the outer surface of the housing 100 can be relatively smooth. This reduces the accumulation of dirt such as dust and facilitates cleaning.

In actual use, the permanent magnet synchronous motor 500 can drive the rope winder 300 to rotate forwardly through the rotor 520 . The rope body 400 may be wound to the rope winder 300 . At this time, the user can control (for example, pull) the operating device to overcome the load resistance through the rope body 400, thereby pulling the rope body 400 out. The rope body 400 can drive the rotor 520 to rotate in reverse through the rope winder 300 . When the user cancels the control of the operating device or reduces the force of controlling the operating device, the load resistance enables the rotor 520 to drive the rope winder 300 to resume normal rotation. The rope body 400 can be wound around the rope winder 300 so that the operating device can be moved to its original position. Repeat the above operations repeatedly, you can carry out strength training, so as to achieve the purpose of fitness or rehabilitation.

Since the torque of the permanent magnet synchronous motor 500 can be controlled, the load resistance can be adjusted, so that the strength of the user to control the operating device can be adjusted. In this way, according to different users, the torque of the permanent magnet synchronous motor 500 can be adjusted in a targeted manner. The way of adjusting the torque of the permanent magnet synchronous motor 500 can be arbitrary. For example, the torque can be adjusted to be quantitative. Exemplarily, the torque can be adjusted as a variable, such as a linear increase or decrease, a non-linear increase or decrease, and the like. In short, according to the actual needs of the user, it can be adjusted to a more suitable torque, thereby improving the effect of fitness or rehabilitation.

Exemplarily, the permanent magnet synchronous motor 500 may be powered by a power source outside the rope winding device. Exemplarily, the rope winding device may further include a power interface 700 . The structure of the power interface 700 can be arbitrary. The power interface 700 may be electrically connected to the permanent magnet synchronous motor 500 . The power interface 700 can be used to electrically connect to a power source outside the rope winding device, so as to supply power to the electromagnetic synchronous motor 500 . Exemplarily, the power supply current may be direct current or alternating current. Exemplarily, the power supply voltage may include various types, including but not limited to low voltages such as 20V, 40V, and 80V, and high voltages such as 220V and 230V.

Exemplarily, the rope winding device may further include a controller. The controller can be electrically connected with the permanent magnet synchronous motor 500 . The controller can realize more precise control of parameters of the permanent magnet synchronous motor 500 , such as controlling torque.

The controller can be built with electronic components such as timers, comparators, registers, and digital logic circuits, or it can be built with single-chip microcomputers, microprocessors, programmable logic controllers (PLCs), digital signal processors (DSPs), field programmable Gate array (FPGA), programmable logic array (PLA), application specific integrated circuit (ASIC) and other processor chips and their peripheral circuits.

In a second exemplary embodiment, as shown in Figures 4-5, the body may include a housing 100'. The stator 510' of the permanent magnet synchronous motor 500' may be disposed inside the housing 100'. Along the radial direction X-X, the stator 510' may surround the rotor 520'. Specifically, the rotor 520' may include a rotor body 521' and an end cover 522'. The rotor body 521' may be disposed inside the housing 100'. The rotor body 521' can rotate within the stator 510' around the axial direction Y-Y. End cap 522' may be attached to rotor body 521'. Therefore, the rotor body 521' can drive the end cover 522' to rotate.

The end cap 522' may be located outside the housing 100' along the axial direction Y-Y of the roping device. In the embodiment shown in the figures, the end cap 522' may be located above the housing 100'. The rope winder 300 may be connected to the end cap 522'. In this way, the rotor body 521' can drive the rope winder 300 to rotate through the end cover 522'. Along the radial direction X-X, the rope winder 300 may surround the housing 100'. To prevent the rope winder 300 from interfering with the housing 100', the rope winder 300 may be spaced apart from the housing 100'. In the embodiment shown in the figures, the housing 100' may project downwardly beyond the rope winder 300. In this way, the rope winder 300 can be prevented from being spaced apart from the platform (such as the ground) on which the rope winder is placed, preventing interference.

In this way, the rope winder 300 can be located outside the rope winding device, and the rope body 400 can be retracted more smoothly, thereby reducing the energy consumption of the permanent magnet synchronous motor 500', so that the rope winding device can be more energy-efficient.

In the first embodiment and the second embodiment, the bottom of the casing 100, 100' may be provided with a mounting hole 120. The roping device may also include a cover 130 . The cover 130 may be detachably connected to the housing 100, 100' through a connector connection or the like. The cover 130 can block the installation hole 120 . Such arrangement facilitates the installation of stators 510, 510' and rotors 520, 520'. Moreover, setting the mounting hole 120 and the cover 130 at the bottom of the casing 100, 100' can also prevent dirt such as dust from entering the inside of the casing 100, 100' through this place, thereby polluting the stator 510, 510' and the rotor 520, 520'.

In a third exemplary embodiment, as shown in FIGS. 6-8 , the body may include a central shaft 600 . Along the radial direction X-X, the stator 510 ″ of the permanent magnet synchronous motor 500 ″ can be sleeved on the central shaft 600 . Along the radial direction X-X, the rotor 520" may surround the stator 510". Along the radial direction X-X, the rope winder 300 can surround the rotor 520". In this way, the rope winder 300 can be located outside the rope winding device, and the rope body 400 can be retracted more smoothly, thereby reducing the number of permanent magnet synchronous motors 500". energy consumption to make the rope winding device more energy-efficient.

Further, the rotor 520" may include a rotor body 521" and an end cover 530". Along the axial direction Y-Y of the rope winding device, the end cover 530" may clamp the rotor body 521". Specifically, the end cover 530" may include Upper end cap 531" and lower end cap 532". The upper end cover 531" and the lower end cover 532" can clamp the rotor body 521". The upper end cover 531" and the lower end cover 532" can be the same or different. Exemplarily, the upper end cover 531" and the lower end cover 532" can clamp the rope winder 300. The end cover 530" can play a protective role to prevent the permanent magnet synchronous motor 500" from being damaged by external force. Moreover, through reasonable arrangement, the outer surface of the end cover 530" can be relatively smooth. This reduces the accumulation of dirt such as dust and facilitates cleaning.

Furthermore, the central shaft 600 may protrude downward from the end cover 530" along the axial direction Y-Y of the roping device. In this way, the end cover 530" can be prevented from being separated from the platform (such as the ground) on which the roping device is placed, prevent interference. Moreover, the protruding central axis 600 can also play a role of positioning, ensuring that the rope winding device remains in the expected position. Exemplarily, the central shaft 600 can also protrude upward from the end cover 530" along the axial direction Y-Y of the rope winding device. In this way, the rope winding device is set upside down without interference.

It should be noted that since the working principle of the second embodiment and the third embodiment is substantially the same as that of the first embodiment, for the sake of brevity, this paper will not describe the working principle of the second embodiment and the third embodiment in detail. .

Exemplarily, as shown in FIGS. 1-8 , the rope winding device may further include a bearing 800 . The bearing 800 can be connected between the

rotors

520, 520', 520" and the main body. The bearing 800 can adopt various types of bearings known in the art or that may appear in the future, including but not limited to rolling bearings or deep groove ball bearings. By providing the bearing 800, the

rotors

520, 520', 520" can be supported, thereby improving the supporting strength. Moreover, the friction force between the

rotor

520, 520', 520" and the main body can be reduced, thereby reducing the energy consumption of the permanent

magnet synchronous motor

500, 500', 500", so that the rope winding device can be more energy-saving.

Further, the bearing 800 may include a first bearing 810 and a second bearing 820 . The first bearing 810 and the second bearing 820 may be distributed along the axial direction Y-Y of the rope winding device. The first bearing 810 and the second bearing 820 may be the same or different. In the embodiment shown in the figures, the first bearing 810 may be located above the second bearing 820 . Compared with the first bearing 810, the second bearing 820 needs to bear more gravity. Therefore, the second bearing 820 can use a bearing with a larger specification than the first bearing 810 .

D-d can be, for example, 0.5 mm, 0.75 mm or 1 mm. Such arrangement can prevent the rope body 400 from overlapping and winding, and ensure smooth retraction and deployment of the rope body 400 .

Furthermore, as shown in FIGS. 6-8 , the groove body 310 may be in a shape that gradually diverges from the bottom of the groove to the opening of the groove. The involute angle a can be between 1-5°. The angle a can be, for example, 1°, 3° or 5°. In this way, the groove body 310 can play a guiding role, so that the rope body 400 can be wound into the groove body 310 more smoothly.
