[0026] The lower limb movement parts include a first pedal 11, a second pedal 13, a rack and pinion transmission mechanism, a motor 29, a first electromagnetic clutch 28, a synchronous belt transmission mechanism and a box 12. The rack and pinion transmission mechanism includes a first rack 15, a second rack 20, a first gear 16, a second gear 19, a third gear 17, a first shaft 30, a second shaft 22, a third shaft 25, a first guide rail 31 and a second guide rail 21. The first pedal 11 and the second pedal 13 are respectively fixed on the first rack 15 and the second rack 20. The surfaces of the first pedal 11 and the second pedal 13 are both provided with irregular protrusions made of rubber material. The outer side of the bottom of the box 12 is supported by four adjustable leveling supports 14.

[0027] The rack and pinion transmission mechanism is bilaterally symmetrical, the first rack 15 and the second rack 20 cooperate with the first guide rail 31 and the second guide rail 21 respectively, the first guide rail 31 and the second guide rail 21 are both fixed to the inner side of the bottom of the box body 12, the first rack 15 and the second rack 20 are respectively meshed with the first gear 16 and the second gear 19 for transmission, the first gear 16 and the second gear 19 are respectively installed on the inner side of the bottom of the box body 12 through the first shaft 30 and the second shaft 22, the lower ends of the first shaft 30 and the second shaft 22 are both installed on the bottom of the box body 12 through rolling bearings, the other ends of the first shaft 30 and the second shaft 22 are both limited by gaskets and nuts to limit the axial movement of the first gear 16 and the second gear 19, the third gear 17 is meshed with the first gear 16 and the second gear 19 for transmission at the same time, the third gear 17 is fixed in the box body 12 through the third shaft 25, and both ends of the third shaft 25 are supported by rolling bearings.

[0028] A motor support 26 is installed on the inner side of the bottom of the box body 12, and the motor 29 is connected to the motor support 26. The output shaft of the motor 29 is connected to the first synchronous pulley 27 through the first electromagnetic clutch 28. The synchronous belt 23 and the second synchronous pulley 24 are transmission-connected, and the second synchronous pulley 24 and the third shaft 25 are fixedly connected.

[0029] By adopting the above technical solution, it is convenient to drive the first synchronous pulley 27 to rotate, thereby realizing the rotation of the second synchronous pulley 24 and the third shaft 25.

[0030] The upper limb motion component and the lower limb motion component are connected through a connecting component, which includes a second electromagnetic clutch 18, a rotating support shaft 9 and a three-way T-shaped support 6.

[0031] By adopting the above technical solution, the upper limb movement parts and the lower limb movement parts work in conjunction, which can maximize the coordinated training of more parts of the body.

[0032] Side lock buffer limit blocks 32 are disposed at both ends of the first guide rail 31 and the second guide rail 21 .

[0033] By adopting the above technical solution, the forward and backward sliding stroke of the pedal is adjusted by adjusting the position of the side lock buffer limit block 32 at the end of the first guide rail 31 and the second guide rail 21, and the adjustment of the size relationship between the pedal stroke and the maximum rotation angle of the upper limb is achieved by changing the transmission ratio of the rack and pinion transmission mechanism.

[0034] One or more springs 33 are provided between the ends of the first rack 15 and the second rack 20 in the sliding direction and the side lock buffer limit block 32 .

[0035] By adopting the above technical solution, the damping feeling and stability of the movement are enhanced.

[0036] Working principle: when the first electromagnetic clutch 28 is energized, the output shaft of the motor 29 is connected to the first synchronous pulley 27 through the first electromagnetic clutch 28, and the second synchronous pulley 24 installed on the third shaft 25 is driven to rotate through the synchronous belt 23, and the third shaft 25 and the third gear 17 rotate accordingly and drive the first gear 16 and the second gear 19 to rotate at the same time, so that the first rack 15 and the second rack 20 slide back and forth, realizing the passive training of the lower limbs driven by the motor 29 for independent movement; at the same time, if the second electromagnetic clutch 18 is energized, the third shaft 25 drives the rotating support shaft 9 to rotate, and the first bracket 5 and the second bracket 7 rotate accordingly, realizing the passive linkage training of the lower limbs and upper limbs; when the first electromagnetic clutch 28 loses power, the motor 29 and the first synchronous pulley 27 are disconnected, realizing the active movement mode driven by human power;

[0037] When the palms are pressed on the first rotating disk 1 and the second rotating disk 2 or the horizontal non-slip handle sleeve 8 on the first bracket 5 and the second bracket 7 is rotated in the same direction around the rotating support shaft 9, the first bracket 5 and the second bracket 7 drive the rotating support shaft 9, the third shaft 25 and the third gear 17 to rotate in the same direction, and the first gear 16 and the second gear 19 rotate in the opposite direction, then the first rack 15 and the second rack 20 slide forward or backward respectively, so that the linkage training of the lower limbs is achieved by the upper limbs; on the contrary, when the soles drive the first pedal 11 and the second pedal 13 to slide back and forth in the opposite direction, the first rack 15 and the second rack 20 drive the first gear 16, the second gear 19 and the third gear 17 to rotate, and then the motion is transmitted to the upper limb motion components through the rotation of the third shaft 25 and the rotating support shaft 9, so that the linkage training of the lower limbs driving the upper limbs is achieved;

[0038] When the second electromagnetic clutch 18 is energized or de-energized, the upper limb motion component and the lower limb motion component are connected or disconnected, realizing the switching between the linkage working mode and the independent working mode of the upper limb motion component and the lower limb motion component. By operating the upper limb motion component and the lower limb motion component, the user's head, neck, upper limbs and waist and back can be twisted and stretched, so that the user's knee joint flexibility and leg muscles can be trained; when the palms and soles of the hands and feet directly contact the first rotating disk 1, the second rotating disk 2 and the first foot pedal 11, the second foot pedal 13 respectively to operate the fitness machine, the protrusions on the surface can massage the palms and soles of the feet; the upper limb motion component and the lower limb motion component work in a linkage manner, which can coordinate the training of more parts of the body to the greatest extent;

[0039] When the first rotating disk 1 or the second rotating disk 2 is emptied on the corresponding first bracket 5 or the second bracket 7, an upper limb independent movement mode is realized in which the upper limb operates the rotating disk to rotate around its own axis.

[0040] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
