[0022] In order to facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0023] See also Figures 1 to 2 As shown, the utility model is a motor-type tension fitness structure, including a fixed base 1 and a tension fitness component 2 arranged on the fixed base 1. The fixed base 1 is made of metal material, for example, the fixed base 1 is made of stainless steel, aluminum alloy or cast iron, and the fixed base 1 is used to limit the external bearing surface or external support.

[0024] The tension fitness component 2 includes a stator component, a rotor component 3 that rotates with the stator component, a wire drum 4 arranged on the rotor component 3, and a pull rope 5 wound on the wire drum 4. The wire drum 4 is roughly in the shape of a hollow disk. In this embodiment, the wire drum 4 has a hollow column and two disks respectively arranged at both ends of the hollow column. The pull rope 5 is used to be wound around the outside of the hollow column, and the two disks are used to block the pull rope 5 wound around the outside of the hollow column.

[0025] The stator and rotor 3 form a motor unit. During use, the motor unit's driving resistance causes the rotor 3 to rotate the cable drum 4 in the reverse direction, thereby automatically reeling the drawstring 5. The user pulls the drawstring 5, overcoming the motor unit's driving resistance. This causes the drawstring 5 to extend and drives the cable drum 4 to rotate forward, achieving exercise and fitness. When the user releases the drawstring 5, the motor unit's driving resistance automatically drives the cable drum 4 in the reverse direction, automatically reeling the drawstring 5.

[0026] The present invention significantly simplifies the design of the motor-driven tension fitness structure, making the entire structure comprise only a stator, rotor 3, cable drum 4, pull cord 5, and mounting base 1. This reduces space requirements and allows users to easily install and use the fitness equipment indoors, significantly enhancing the user experience. Furthermore, mounting base 1 facilitates assembly and disassembly of the motor-driven tension fitness structure with external load-bearing surfaces or support members, greatly enhancing ease of use.

[0027] The fixing base 1 has a U-shaped support frame with two spaced-apart, parallel support arms 6, each of which is substantially a straight plate. The motor unit and the cable drum 4 are located between the two support arms 6, and the left and right ends of the stator are detachably mounted on the two support arms 6. The two support arms 6 support and fix the two ends of the stator, respectively, so that the two ends of the motor unit are subjected to balanced force. Compared with a fixed connection of the motor unit to the fixing base 1 via one end, this prevents the entire motor unit from rotating when the pull cord 5 is pulled, thereby preventing improper use.

[0028] The stator assembly comprises a fixed shaft 7 and a stator unit mounted on the outside of the fixed shaft 7. The fixed shaft 7 is generally a straight cylinder. The rotor assembly 3 surrounds the stator unit, and both ends of the rotor assembly 3 are rotatably mounted on the outside of the fixed shaft 7 via a first bearing. That is, the inner ring of the first bearing is mounted on the outside of the fixed shaft 7, and the rotor assembly 3 is mounted on the outside of the outer ring of the first bearing.

[0029] One end of the wire drum 4 is fixedly mounted on one end of the rotor 3. The wire drum 4 is rotatably mounted on the outside of the fixed shaft 7 via a second bearing. Specifically, the inner ring of the second bearing is mounted on the outside of the fixed shaft 7, and the wire drum 4 is mounted on the outside of the outer ring of the second bearing. The left and right ends of the fixed shaft 7 extend through the motor unit and are mounted on two support arms 6.

[0030] The motor-type tension fitness structure also includes two nut parts 8, threaded columns are respectively provided at both ends of the fixed shaft 7, and the support arm 6 has a through hole for accommodating the threaded columns. The two nut parts 8 are respectively screwed on the threaded columns at both ends of the fixed shaft 7, and the two support arms 6 are located between the two nut parts 8. The ends of the two nut parts 8 that are close to each other respectively abut against the ends of the two support arms 6 that are away from each other.

[0031] During the installation or removal process of the fixing base 1 and the motor unit, the fixing shaft 7 can be quickly installed on the support arm 6 by means of the forward rotation of the nut member 8, and the fixing shaft 7 can be quickly removed from the support arm 6 by means of the reverse rotation of the nut member 8. Preferably, a plurality of friction ribs are provided on the outer side of the nut member 8, and the friction ribs extend along the central axis of the nut member 8, and the plurality of friction ribs are arranged in a ring array around the central axis of the nut member 8. The provision of the friction ribs greatly increases the friction between the nut member 8 and the user's hand when the user grasps the nut member 8, making it easier for the user to manually rotate the nut member 8 to achieve manual installation or removal of the fixing base 1 and the motor unit.

[0032] The support frame includes a crossbeam 9 connected to one end of each of the two support arms 6. Crossbeam 9 is a generally straight slat. The left and right ends of the stator are respectively located on the ends of the two support arms 6 away from crossbeam 9. Crossbeam 9 is equipped with suction cups 11 for adsorbing onto an external support surface. This feature allows the mounting base 1 to quickly adhere to a support surface (e.g., a floor) through suction, enabling quick and convenient installation of the motor-driven tension fitness structure, enhancing installation convenience.

[0033] Mounting base 1 includes a support rod 10, which is generally a straight cylindrical rod, disposed in the middle of crossbeam 9. Support rod 10 and support arm 6 are located on the upper and lower sides of crossbeam 9, respectively. A suction cup 11 is located at the end of support rod 10 away from crossbeam 9. Suction cup 11 is equipped with a valve that facilitates separation of suction cup 11 from the support surface. When the motor-driven tension fitness structure needs to be disassembled, the valve is triggered, allowing air to enter the space between suction cup 11 and the support surface, allowing suction cup 11 to be easily separated from the support surface, thus improving the ease of disassembly of mounting base 1.

[0034] The motorized tension fitness structure also includes a guide frame mounted on the fixed base 1. The guide frame has a receiving hole 12 for accommodating the guide rope 5. The guide frame automatically guides the rope 5 in the direction of pulling out or reeling, preventing excessive deflection of the rope 5 that could prevent it from properly winding around the reel 4, thereby improving the yield rate of the rope 5 during reeling and unwinding.

[0035] The guide frame passes through a clearance hole 13 connected to the accommodating hole 12, and the pull rope 5 enters and exits the accommodating hole 12 through the clearance hole 13; when the pull rope 5 is damaged during actual use, the user can replace it with a new pull rope 5, and use the clearance hole 13 to enable the pull rope 5 to enter the accommodating hole 12 of the guide frame or move the pull rope 5 in the accommodating hole 12 out through the clearance hole 13.

[0036] The drawstring 5 comprises an inelastic core and an elastic sheath covering the core. The outer diameter of the core is less than or equal to the width of the clearance hole 13, while the outer diameter of the elastic sheath is greater than the width of the clearance hole 13. The diameter of the receiving hole 12 is also greater than the outer diameter of the elastic sheath. Due to the structural characteristics of the drawstring 5, while ensuring that the drawstring 5 can enter the receiving hole 12 through the clearance hole 13, the probability of the drawstring 5 in the receiving hole 12 being dislodged through the clearance hole 13 is reduced, ensuring that the drawstring 5 is stably retained within the receiving hole 12.

[0037] The guide frame comprises a first plate 14 fixedly connected to the fixing base 1, and a second plate 15 rotatably engaged with the first plate 14. The receiving hole 12 is provided in the second plate 15 and extends through the second plate 15 along its thickness. Due to the relative rotation between the first and second plates 14, when the user pulls the drawstring 5 and it contacts the second plate 15, the second plate 15 can rotate relative to the first plate 14. Compared to a case where the second plate 15 cannot rotate relative to the first plate 14, this reduces the chance of the inner wall of the receiving hole 12 in the second plate 15 cutting the drawstring 5, thereby extending the service life of the drawstring 5.

[0038] One end of the drawstring 5 is attached to the reel 4, and the other end is provided with a loop 16. A hollow tube 17 is rotatably mounted on the outer side of the loop 16 for easy gripping. The length of the hollow tube 17 is less than one-third of the length of the loop 16. During actual use, the user grasps the hollow tube 17 and rotates it relative to the loop 16, preventing the drawstring 5 from rubbing against the user's palm and improving the user experience.

For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scope. The content of this specification should not be understood as limiting the present invention.
