[0067] In order to drive the pedal 17 to swing up and down through the drive motor 23, an electric drive member is further provided. The electric drive member includes: a mounting bracket 22, a drive shaft 26, a worm gear 25, a worm 24, a first swing plate 27, a second swing plate 31, a first hinge shaft 28, a second hinge shaft 30, a first assembly block 37, a second assembly block 38, and a connecting plate 29.

[0068] The mounting bracket 22 is fixedly connected to the base 11, the drive shaft 26 is rotatably connected to the mounting bracket 22, the worm gear 25 is fixedly connected to the drive shaft 26, and the worm 24 is fixedly connected to the drive motor 23.

[0069] Working or installation process:

[0070] The user steps on the two pedals 17; and controls the driving motor 23 to start. The output rotating shaft of the driving motor 23 drives the worm 24 to rotate. The worm 24 drives the worm wheel 25 to rotate by meshing with the worm wheel 25. The worm wheel 25 drives the driving shaft 26 to rotate. The driving shaft 26 drives the first swing plate 27 to perform a circular rotation around the central axis of the driving shaft 26. Since the first swing plate 27 is rotationally connected to the first hinge shaft 28, the first swing plate 27 drives the first hinge shaft 28 to rotate around the central axis of the driving shaft 26 while the first hinge shaft 28 can rotate around its own central axis. The first hinge shaft 28 rotates circularly following the first swing plate 27 and pushes the first assembly block 37. The first assembly block 37 drives the connecting plate 29 to move. While the connecting plate 29 follows the movement of the first assembly block 37, it drives the second hinge shaft 30 to rotate around the axis of the first ejector rod 32 through the second assembly block 38. The second hinge shaft 30 synchronously drives the second swing plate 31 to perform a circular rotation around the axis of the first ejector rod 32. Since the distance from the central axis of the first ejector rod 32 to the central axis of the second hinge shaft 30 is greater than the distance from the central axis of the driving shaft 26 to the central axis of the first hinge shaft 28, and the height from the central axis of the first ejector rod 32 to the top wall of the base 11 is greater than the height from the central axis of the driving shaft 26 to the top wall of the base 11, the second swing plate 31 pulls the first ejector rod 32 while performing a circular rotation around the central axis of the first ejector rod 32. The lever plate 20 is pulled by the first ejector rod 32 and causes the lever plate 20 to deflect around the central axis of the lever shaft 21. The lever plate 20 drives the first bearing 33 and the second bearing 35 to perform a circular deflection around the central axis of the lever shaft 21 through the first ejector rod 32 and the second ejector rod 34 respectively. As a result, the first bearing 33 presses against and contacts one of the rubber pads 36 and pushes the pedal 17 on the rubber pad 36 to deflect upward around the central axis of the socket shaft 14. At this time, the second bearing 35 no longer presses against and contacts the rubber pad 36 and the other pedal 17 deflects downward around the central axis of the socket shaft 14; or the second bearing 35 presses against and contacts the other rubber pad 36 and pushes the other pedal 17 to deflect upward around the central axis of the socket shaft 14. The first bearing 33 no longer presses against and contacts the rubber pad 36 and the other pedal 17 deflects downward around the central axis of the socket shaft 14.

[0071] Through the driving motor 23, one pedal 17 is rotated downward and the other pedal 17 is rotated upward, and the up-and-down movement frequency of the two pedals 17 is controlled by controlling the rotation speed of the driving motor 23, so as to reduce the negative impact of the stepping movement on the leg joints.

[0072] The above description is only some preferred embodiments of the present disclosure and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept. For example, the technical solutions formed by mutually replacing the above features with the technical features (but not limited to) disclosed in the embodiments of the present disclosure that have similar functions.
