[0049] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0051] As Figure 1 shown, this embodiment provides a treadmill with a visual perception shock absorption function, including a treadmill main body 1. The lower part of the treadmill main body 1 is rotatably connected with a running belt 2. An upper running board 3 and a lower running board 4 are arranged side by side from top to bottom inside the running belt 2. An acceleration sensor 31 is arranged on the bottom surface of the upper running board 3. A number of filling cushions 5 are regularly arranged between the upper running board 3 and the lower running board 4.

[0052] In this embodiment, the running belt 2 is in contact with the upper running board 3, facilitating the upper running board 3 to directly bear the pressure when the user's foot steps down during running.

[0053] Further, the upper running board 3 and the lower running board 4 together form the running platform part of the treadmill.

[0054] Specifically, the thickness of the upper running board 3 is less than that of the lower running board 4. When the user's foot exerts force on the upper running board 3, the thinner board body sinks more significantly after being stressed. After the upper running board 3 is compressed and deformed and rebounds, it provides a buffering force to the user's foot, avoiding ankle injuries to the user caused by the hard running board, and the elastic running board has a longer service life and is not easily broken.

[0055] In this embodiment, the acceleration sensor 31 is used to calculate the sinking distance of the upper running board 3 to evaluate the amplitude condition of the upper running board 3.

[0056] In this embodiment, one side of the filling buffer pad 5 is flat and the other side is arc-shaped, which can improve the pressure dispersion effect when the filling buffer pad 5 is subjected to an external force, thereby improving the buffering effect of the filling buffer pad 5 and enhancing the running comfort of the user.

[0057] Further, a number of transverse through holes are regularly provided in the middle of the filling buffer pad 5 to improve the buffering effect of the filling buffer pad 5, avoid the damage degree when the filling buffer pad 5 is subjected to external pressure, and extend the service life of the filling buffer pad 5.
