[0012] Working principle of the present invention:

[0013] When running, when the treadmill detects that the user's weight is less than the weight set for the treadmill, the electronic control program will control the motor to pull the movable platform to the left. At this time, the running board will arch upward, increasing the force strength of the running board. The downward deformation of the running board will be reduced, and people will feel that the treadmill is a little harder when running.

[0014] When running, when the treadmill detects that the user's weight is less than the weight set for the treadmill, the electronic control program will control the motor to push the movable platform to the right. At this time, the upward arch of the running board will decrease, reducing the force strength of the running board, and the downward deformation of the running board will increase. People will feel that the treadmill is soft when running.

[0015] Compared with the prior art, the present invention has the following advantages: the present invention utilizes the translation of the movable platform to cause the running board to arch upward and lower, thereby realizing the function of intelligently adjusting the softness and hardness of the running platform.
