[0002] In the field of electric control fitness equipment, motor is often used as the power source of resistance output, and the pull rope is used as the carrier of resistance transmission and cooperates with the motor. However, in actual application, the pull rope is prone to accumulation and disorder during winding. For example, the Chinese patent document with publication number CN118634472A discloses a multi-motor pull fitness machine, which includes an external motor, a winding disc, and a pull rope. The rotor of the external motor is coaxially connected to the winding disc, and one end of the pull rope is connected to the winding disc, and the other end is used for the user's pulling action.

For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0027] Figures 1 to 5 An embodiment of the utility model for the rope arranging device of the electrically controlled fitness equipment is shown, the rope arranging device for the electrically controlled fitness equipment of the embodiment, including mounting base 4, tension rope 1, winding wheel 2 and the driving motor 3 of driving winding wheel 2 rotation, one end of tension rope 1 is wound on winding wheel 2, winding wheel 2 and driving motor 3 are arranged on mounting base 4, winding wheel 2 is provided with the rope arranging groove 21 for embedding tension rope 1, the rope arranging groove 21 is arranged along the axial spiral of winding wheel 2, the rope arranging device for the electrically controlled fitness equipment further includes the rope guiding mechanism 5 arranged on mounting base 4, one end of tension rope 1 away from winding wheel 2 passes through rope guiding mechanism 5, and the rope guiding mechanism 5 is used to guide tension rope 1 to embed in the rope arranging groove 21 when winding tension rope 1 on winding wheel 2.

[0028] This rope-laying device for electronically controlled fitness equipment uses a drive motor 3 to rotate a rope-winding wheel 2, causing the tension rope 1 to wind around. A rope-guiding mechanism 5 simultaneously guides the tension rope 1 to smoothly embed into the rope-laying groove 21 and arrange it neatly. By creating spirally arranged rope-laying grooves 21 on the rope-winding wheel 2, and coordinating with the rope-guiding mechanism 5 to guide the tension rope 1 into the grooves, the neatness of the winding of the tension rope 1 is improved, reducing friction and compression during winding, extending the service life of the tension rope 1, and avoiding jamming or abnormal resistance during exercise caused by winding problems. This makes the exercise process smoother, enhances the comfort and reliability of the electronically controlled fitness equipment, reduces potential safety hazards caused by winding problems of the tension rope 1, and improves the safety of using the electronically controlled fitness equipment.

[0029] Further, see Figures 1 to 3 In this embodiment, the rope guiding mechanism 5 includes a rope guiding seat 53 and a rotary transmission unit 51, a twisted shaft 52, and a guide shaft 6 disposed on the mounting base 4. The rotary transmission unit 51 is connected to the winding wheel 2 and the twisted shaft 52 respectively, so as to drive the twisted shaft 52 to rotate around the axis of the twisted shaft 52 when the winding wheel 2 rotates. The rope guiding seat 53 is threadedly connected to the twisted shaft 52, so as to drive the rope guiding seat 53 to move along the axial direction of the twisted shaft 52 when the twisted shaft 52 rotates. The guide shaft 6 is parallel to the twisted shaft 52, and the guide shaft 6 passes through the rope guiding seat 53 and slides with the rope guiding seat 53. The end of the tension rope 1 away from the winding wheel 2 passes through the rope guiding seat 53. When the drive motor 3 drives the winding wheel 2 to rotate, it will cause the winding wheel 2 to rotate. The winding wheel 2 drives the twisted shaft 52 to rotate through the rotation transmission unit 51. Since the guide shaft 6 passes through the guide seat 53 and slides with the guide seat 53, the guide shaft 6 will prevent the guide seat 53, which is threadedly connected to the twisted shaft 52, from rotating with the twisted shaft 52. Thus, the guide seat 53 moves along the axial direction of the twisted shaft 52 when the twisted shaft 52 rotates.
