(2) The first main body support frame 220 of the treadmill main body 200 is designed to be elastic, and the second level of shock absorption is achieved through the elastic deformation of the first main body support frame 220;

(3) Between the bottom surface of the treadmill main body 200 and the top surface of the bracket main body 100, a plurality of symmetrically distributed suspension shock absorbers 300 are arranged, and the third level of shock absorption is achieved through the elastic deformation of the suspension shock absorbers 300;

(4) At least one pair of limit buffers 400 symmetrically distributed on the bottom of the treadmill body 200 or the top of the bracket body 100 is arranged, and the fourth level of shock absorption is achieved through the elastic deformation of the limit buffers 400;

Since the treadmill main body 200 and the support main body 100 belong to a separate connection mode, that is, the treadmill main body 200 is bridged with the support main body 100 through the suspension shock-absorbing rubber columns 300, the fixed positions of the four suspension shock-absorbing rubber columns 300 are vertically distributed in Above the supporting base 500, when the user moves, the main body 200 of the treadmill deforms along with the footsteps of the user, and the vibration force generated by the deformation of the main body 200 of the treadmill is absorbed by the elasticity of the material itself of the running board 210 and the first main body support frame 220, and then reduced by the suspension. The vibration rubber column 300, the limit buffer rubber block 400, and the support shock-absorbing rubber pad 600 are digested and absorbed layer by layer, and finally directly transmitted to the ground, while the main body of the bracket 100 is hardly affected by vibration, avoiding vibration, so as to achieve an ultimate comfort Excellent running experience, when the user is exercising, only the main body of the treadmill 200 is deformed for shock absorption, and the main body of the bracket 100 has a suspension shock absorption effect that does not move at all, and at the same time creates an ultimate visual experience effect for the user to watch the screen.
