Independent suspension vibration damping mechanism of running platform of a treadmill

An independent suspension vibration damping mechanism of running platform of a treadmill comprising:

• a chassis;
• and
• a runway frame,
• wherein a front end of the runway frame is suspended on the chassis through a suspension structure and when the runway frame is subjected to a downward force that forces the front end of the runway frame to descend, the suspension structure assists the front end of the runway frame to rise and reset;
• wherein the suspension structure comprises at least one cantilever, a first end of the cantilever is hinged on the runway frame, a second end of the cantilever is connected with the chassis through an elastic component, and a middle part of the cantilever is hinged on the chassis;
• wherein the runway frame comprises a frame body, a cantilever frame is fixed at a lower side of a front of the frame body, the cantilever is hinged at a front end of the cantilever frame, a damping cylinder is arranged between the chassis and a middle of the runway frame, a first end of the damping cylinder is fixedly connected with the chassis, and a second end of the damping cylinder is fixedly connected with the runway frame;
• wherein two sets of the suspension structure are symmetrically disposed on both sides of the runway frame;
• wherein the elastic component comprises a transmission rod, a first end of the transmission rod is hinged with the cantilever, a second end of the transmission rod passes through the chassis, an elastic blocking body is fixed to the second end of the transmission rod, and the elastic blocking body abuts on the chassis;
• and
• wherein the cantilever is L-shaped and a corner of the cantilever is hinged to the chassis, and a length of the first end of the cantilever connected to the runway frame is longer than a length of the second end of the cantilever connected to the elastic component.
