Multi-stage buffering and damping device suitable for treadmill

The invention discloses a multi-stage buffering and damping device suitable for a treadmill, relates to the technical field of damping of treadmills, and mainly aims to solve the technical problem that for runners with different weights, the treadmill does not have a targeted adjusting function and is difficult to realize an adaptive running buffering and damping effect. According to the invention, a body pressure information value is obtained through comprehensive numerical calculation of a preset pressure sensor and amplitude, a first-level signal instruction, a second-level signal instruction and a third-level signal instruction are obtained through intelligent analysis of the body pressure information value, and accurate damping adjustment is carried out according to the instructions. In the buffering and damping adjusting process, the function of adaptively adjusting the damping strength according to the body weight of the runner is achieved, the impact force of the knees and ankles of the runner can be
