The invention relates to a novel student autonomous mechanism innovative design experiment platform which comprises a rectangular frame body. The rectangular frame body comprises a top beam with scales printed, longitudinal beams and a base. Foldable supporting foot stands used for firmly fixing the experiment platform are arranged on the front sides and the rear sides of the longitudinal beams respectively. A linear guide rail fixed to the longitudinal beams and arranged transversely is arranged below the top beam, and a linear guide rail fixed to the longitudinal beams and arranged transversely is arranged above the base. A plurality of sliding blocks capable of conducting fixing and sliding are evenly distributed on the linear guide rails, and a rod piece is fixedly connected between every two corresponding sliding blocks of the two linear guide rails. The rod pieces are provided with a plurality of U-shaped rod piece sliding blocks which can conduct fixing and sliding, and mechanical part models are fixed to the rod piece sliding blocks. According to the novel student autonomous mechanism innovative design experiment platform, due to the fact that the experiment platform is set up, the plane movement of a mechanism can be simply and vividly demonstrated, students can be helped to conduct mechanism innovation design experiments, and the students can be helped to better master and understand the related knowledge of the mechanism movement.
