Abstract: A hinge and a mobile terminal to resolve poor use effect of a foldable electronic device. The hinge includes a main body, and a first folding assembly and a second folding assembly that are symmetrically disposed along the main body. When the first folding assembly and the second folding assembly are rotated toward each other, a length of the hinge can be extended, and an accommodation space for accommodating the flexible display can be formed. When the first folding assembly and the second folding assembly are rotated away from each other, the length of the hinge can be reduced, and a support surface for supporting the flexible display can be formed, so that the flexible display cannot be stretched, compressed, or the like during folding and unfolding, thereby improving the use effect and safety of the mobile terminal.
