Multi-functional soft walking board assembly with better shock absorbing and buffering effect

A treadmill comprising:

• two side frames, a walking board assembly mounted between the two side frames, and a walking belt encircling the walking board assembly;
• wherein:
• the walking board assembly includes a support plate, a shock-absorbing layer, a wear-resistant layer, and at least two thermal conducting strips;
• the support plate is made of a composite board;
• the shock-absorbing layer has a soft feature;
• the shock-absorbing layer has a bottom face abutting a top face of the support plate;
• the shock-absorbing layer has a front end with a thickness of 3 mm to 6 mm and a rear end with a thickness of 1 mm to 3 mm;
• the shock-absorbing layer has a top face formed with a downward sloping plane extending longitudinally from the front end to the rear end of the shock-absorbing layer;
• the shock-absorbing layer has a length less than a length of the support plate;
• the shock-absorbing layer has a width less than a width of the support plate;
• the wear-resistant layer has a flexible feature;
• the wear-resistant layer has a thickness of 0.05 mm to 0.5 mm;
• the wear-resistant layer has a length more than the length of the shock-absorbing layer;
• the wear-resistant layer has a width more than the width of the shock-absorbing layer;
• the width of the wear-resistant layer is less than the width of the support plate;
• the wear-resistant layer has a bottom face abutting the top face of the shock-absorbing layer and the top face of the support plate;
• the support plate has two sides located outside of two sides of the wear-resistant layer respectively, with a width defined between each of the two sides of the support plate and each of the two sides of the wear-resistant layer;
• the support plate is affixed to the two side frames by provision of the width remaining at the two sides of the support plate;
• each of the at least two thermal conducting strips is made of metal foil and has a flexible feature;
• each of the at least two thermal conducting strips has a thickness of 0.05 mm to 0.5 mm;
• each of the at least two thermal conducting strips has a longitudinal length less than the length of the wear-resistant layer and more than the length of the shock-absorbing layer;
• the at least two thermal conducting strips are parallel with each other;
• the at least two thermal conducting strips longitudinally abut the shock-absorbing layer and are arranged at a middle position of the support plate;
• each of the at least two thermal conducting strips has a front end and a rear end abutting the top face of the support plate;
• and
• the wear-resistant layer completely covers the at least two thermal conducting strips and the shock-absorbing layer on the support plate.
