[0002] With the continuous improvement of living standards, people are paying more and more attention to their health and using different fitness equipment to exercise different parts of the body. This is especially true for office workers, who often spend most of their work sitting in front of a computer and commuting by car, which is extremely detrimental to their health. As a result, a variety of fitness equipment has emerged, allowing people to exercise their upper limbs, lower limbs, waist, abdomen, and other parts of the body. However, going to the gym is both expensive and time-consuming. Exercising at home requires purchasing several pieces of equipment, as existing training equipment mostly focuses on single exercises. This requires a lot of space, making a small house even more crowded, and the cost is also high, which is obviously not ideal. Therefore, how to design a modular fitness equipment has become an urgent problem for those in this field.

DETAILED DESCRIPTION

[0026] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0027] As shown in Figures 1-8, a waist-twisting stepper comprises a base plate 1 and a movable plate 2 rotatably mounted on the base plate 1. An upwardly extending flange 25 is fixedly mounted on the outer periphery of the base plate 1 and the movable plate 2 to prevent damage during transportation. Two pedals 3 capable of reciprocating are movably mounted on the movable plate 2 via an eccentric wheel 4. A driving mechanism 5 for driving the eccentric wheel 4 to rotate is provided on the movable plate 2. The driving mechanism 5 drives the movable plate 2 to reciprocate via a transmission mechanism 6. While the driving mechanism 5 drives the eccentric wheel 4 to rotate and achieve reciprocating swing of the pedals 3, the transmission mechanism 6 mounted on the driving mechanism 5 enables the movable plate 2 to reciprocate in the horizontal direction. The user can achieve stepping by the up-and-down swinging pedals 3 and waist-twisting by the reciprocating swinging movable plate 2 in the horizontal direction. Two actions are achieved by one driving mechanism 5, resulting in a simple structure and a small size.

[0028] A shell 26 is fastened to the base plate 1, and a display panel 27 for displaying the speed is provided on the shell 26. The shell 26 is fastened above the base plate 1 and the driving mechanism 5. The speed of the driving mechanism 5 is adjusted by the controller 28 to adjust the gear position, and the data information is displayed through the display panel 27. The controller 28 can be adjusted by the remote control, which is convenient to operate. The entire machine can be started by the remote control or the physical button 29 on the display panel 27, and the speed can be adjusted by the remote control or the physical button 29 to achieve more exercise methods.

[0029] The driving mechanism 5 includes a motor 7 provided on the movable plate 2 and a drive shaft 8 rotatably provided on the movable plate 2. The two eccentric wheels 4 are eccentrically provided at both ends of the drive shaft 8. The motor 7 drives the drive shaft 8 to rotate via a reduction mechanism 9. A mounting base 10 for mounting the pedal 3 is fixedly provided on the movable plate 2. One end of the pedal 3 is rotatably provided on the mounting base 10. The drive shaft 8 is rotatably provided on the other end of the mounting base 10. A collar 11 is rotatably provided below one end of the pedal 3 facing the eccentric wheel 4. The collar 11 is sleeved on the outer periphery of the eccentric wheel 4. A plurality of clearance grooves 12 are provided on the movable plate 2, which pass through the movable plate 2. The clearance grooves 12 are located directly below the eccentric wheel 4. The motor 7 drives the drive shaft 8 to rotate, so that the eccentric wheels 4 at both ends of the drive shaft 8 rotate around the drive shaft 8. One end of the pedal 3 is rotatably set on the rotating seat 15, and the other end of the pedal 3 is sleeved on the above-mentioned eccentric wheel 4 through the collar 11, and the upper end of the collar 11 is rotatably set on the pedal 3. When the eccentric wheel 4 rotates, it drives the collar 11 to perform circular motion around the drive shaft 8. At the same time, the collar 11 swings back and forth around the upper end of the collar 11, and the pedal 3 is driven by the collar 11 to realize the up and down reciprocating rotation of the pedal 3, thereby realizing the stepping action.

[0030] The movable plate 2 is rotatably mounted on the base plate 1 via a rotating shaft 13. A plurality of guide wheels 14 are rotatably mounted on the lower end of the movable plate 2, which abut against the upper end of the base plate 1. The guide wheels 14 are evenly distributed around the rotating shaft 13 at the lower end of the movable plate 2. Six guide wheels 14 are provided. Each guide wheel 14 is mounted on the lower end surface of the movable plate 2 via a rotating base 15. The transmission mechanism 6 includes an opening 16 opened on the movable plate 2 and passing through the movable plate 2, the opening 16 is located below the above-mentioned drive shaft 8, and a cover plate 17 is fixedly fastened above the opening 16, and a first bevel gear 18 extending in the vertical direction is rotatably provided on the cover plate 17, and a second bevel gear 19 meshing with the above-mentioned first bevel gear 18 is fixedly provided on the drive shaft 8, and the second bevel gear 19 rotates synchronously with the drive shaft 8, and a connecting plate 20 is fixedly provided at the lower end of the above-mentioned first bevel gear 18, and a guide block 21 located directly below the above-mentioned opening 16 is fixedly provided on the base plate 1, and a guide groove 22 extending in the horizontal direction is provided on the guide block 21, and a guide rod 23 extending downward and inserted in the above-mentioned guide groove 22 is fixedly provided on one end of the above-mentioned connecting plate 20 away from the above-mentioned first bevel gear 18. When the connecting plate 20 is driven to rotate by the first bevel gear 18, the guide rod 23 always moves back and forth in the guide groove 22. The lower end of the guide rod 23 is rotatably provided with a roller 24, which abuts against the inner wall of the guide groove 22. During the rotation of the movable plate 2, the guide wheel 14 that always abuts against the bottom plate 1 is used to bear force and guide the movable plate 2, so that the rotation of the movable plate 2 is smoother. The motor 7 drives the drive shaft 8 to rotate after passing through the reduction mechanism 9, and drives the first bevel gear 18 to rotate through the second bevel gear 19 that is always engaged. The first bevel gear 18 drives the guide rod 23 to rotate around the center of the first bevel gear 18 through the connecting plate 20, and the guide groove 22 is opened so that the guide rod 23 can only move along the length direction of the guide groove 22. Through the rotation of the first bevel gear 18, the guide rod 23 is reciprocated in the guide groove 22 to realize the reciprocating rotation of the movable plate 2 in the horizontal direction around the rotating shaft 13, realizing the twisting action.

[0031] A shift fork 30 is provided in the housing 16 for driving the second bevel gear 19 to move along the length direction of the drive shaft 8. After the second bevel gear 19 is driven by the shift fork 30 to move, it engages with the first bevel gear 18 or disengages from the first bevel gear 18, so that the stepper can perform the stepping function alone or twist while stepping.
