[0002] For treadmills in the prior art, when users of different weights or users walk or run at different speeds on the treadmill platform (referred to as the treadmill), the bending deformation amplitude (referred to as the amplitude) of the running board on the treadmill is different. If the amplitude is too small (insufficient shock absorption), the buffering effect is not obvious, and the treadmill does not absorb the user's impact force enough, resulting in poor comfort of the treadmill; if the amplitude is too large (too much shock absorption), the rebound of the treadmill's running board will produce excessive reaction force, which will cause a large counter-impact on the user's lower limbs and knee joints, and easily cause sports injuries. It can be seen that the shock absorption hardness of the running board greatly affects the user's running experience. Different shock absorption hardness is required according to different usage scenarios to have a better user experience; some existing treadmills are not convenient for adjusting the shock absorption of the treadmill according to usage requirements, and the user experience is not good; or the shock absorption adjustment structure is complex and the production cost is high.
