Electric lifting slope adjustment device having vibration damping function and treadmill

An electric lifting slope adjustment device having a vibration damping function applied to a treadmill, wherein the treadmill comprises a frame and a running platform, the frame is a rectangular frame and has a first inner wall, a second inner wall and a third inner wall, the first inner wall and the second inner wall are arranged opposite each other, the third inner wall is parallel to a first direction and is perpendicular to the first inner wall and the second inner wall respectively, and the running platform is provided between the first inner wall and the second inner wall;

• and wherein the electric lifting slope adjustment device having a vibration damping function comprises:
• two lifting supports, each of the lifting supports having a rotating end, the rotating ends of the two lifting supports being rotatably connected to the first inner wall and the second inner wall respectively;
• a rotating shaft extending along the first direction, two ends of the rotating shaft in an extending direction being respectively connected to the two lifting supports;
• a driving component hinged to the third inner wall, the driving component comprising a lifting motor and a lifting rod, wherein the lifting rod extends along a second direction, and a driving end of the lifting motor is connected to the lifting rod, so that the lifting rod can extend and retract back and forth along an extending direction thereof;
• and
• a vibration damping assembly comprising a mounting frame and a vibration damping block, wherein the mounting frame is connected to the rotating shaft and is hinged to an end portion of the lifting rod close to the rotating shaft, the vibration damping block extends along an axial direction perpendicular to the rotating shaft, and two ends of the vibration damping block in the extending direction are respectively connected to the mounting frame and the end portion of the lifting rod close to the rotating shaft.
