Method for establishing three-dimensional flexible deformable bump and deformable bump

The invention discloses a method for establishing a three-dimensional flexible deformable bump and the deformable bump. The method comprises the following steps: setting an initial molded surface and a target molded surface of a deformable bump, and determining the maximum deformation, the thickness and the material of a skin and the size of a base; the base is covered with the skin and sealed, and a cavity is formed in the base; a plurality of supporting columns are arranged in the cavity based on an equivalent stiffness method, one end of each supporting column is fixed to the base, the other end of each supporting column is fixed to the inner surface of the skin, the deformable bulge is established, the size of the cavity is changed, and the curved surface where the skin is located is driven to deform to a target molded surface. The cavity is filled with gas with a certain pressure intensity, the flexible layer is driven to deform to a certain degree, the air inlet channel can deform to a better pneumatic
