Then, as shown in fig. 6B, when the eccentric shafts 320 continue to rotate, the driving plates 410 of the driving mechanisms 400 drive the linking shafts 420 to descend to the lowest point along the first direction D1, and sequentially link to the housing 500 from the fixed linking plates 432 and the fixed seats 433, and sequentially link to the housing 500 from the movable linking plate 443, the two second connecting plates 444 and the fixed seats 445, so that the housing 500 ascends to the highest point along the second direction D2.

In detail, the main axis of the eccentric shaft 320 may be different from the eccentric axis by 2 millimeters (mm). In fig. 6A, when the housing 500 is at the lowest point, the height between the housing 500 and the foot 600 is L1, and the height L1 may be 117.83mm. In fig. 6B, when the housing 500 is at the highest point, the height between the housing 500 and the foot rest 600 is L2, and the height L2 may be 119.45mm. Therefore, the difference between the height L1 and the height L2 can be 1.62mm, which is the actuating stroke of the housing 500, but the present invention is not limited thereto. In other embodiments, the present invention can be realized by changing the pivot position between the supporting base 431 and the fixed linking plate 432; alternatively, the pivot position between the first connecting plate 442 and the movable linking plate 443 is changed to adjust the operation stroke of the housing 500 according to the user's requirement. In addition, the pivot point between the movable linking plate 443 and the two first connecting plates 442 can be a movable fulcrum a. When the other ends of the two first connecting plates 442 are pushed by the movable linking plate 443 to swing back and forth, the movable pivot a reciprocates along a third direction D3, and the first direction D1, the second direction D2 and the third direction D3 are different from each other.

To sum up, the utility model has the advantages of it is following: firstly, when the user steps or stands on the upper and lower movement device, the whole body of the user can generate circulatory rhythm, so that all parts of the body can move back and forth periodically. And secondly, the auxiliary shell of the buffer unit supports pressure, so that the driving mechanism is facilitated to reduce torsion, and the somatosensory impact degree of a user when the upper and lower rhythm motors are reset is improved through the buffer unit. Thirdly, the linkage shaft is used for linking the first transmission component and the second transmission component and simultaneously connecting and driving the shell, so that the upper and lower rhythm machines not only have simple integral structures, but also reduce unnecessary components and parts, thereby greatly reducing the manufacturing cost. And fourthly, the transmission mechanisms are synchronized by utilizing the connecting piece or the integrally formed linkage shaft, so that the transmission mechanisms can still maintain synchronous action when uneven stress is applied to the surface of the shell, and further, the parts are prevented from being broken or loosened due to irregular shaking.

Although the present invention has been described with reference to the above embodiments, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
