Heat sink and terminal device

Abstract

The radiator includes a heat dissipation assembly and a fixing mechanism. The fixing mechanism includes a fixing member, a hinge, a torsion spring, and a movable plate. The fixing member and the heat dissipation assembly are fixed; the hinge is used to switch between an initial position, a first position, and a second position; the torsion spring rotatably connects the fixing member and the hinge; the movable plate and the hinge are rotatably connected. When the hinge is in the initial position, there is an initial gap between the movable plate and the heat dissipation assembly; when the hinge is in the first position, the torsion spring has torsional deformation and abuts against the fixing member and the hinge, and there is a first gap between the movable plate and the heat dissipation assembly; when the hinge is in the second position, the torsion spring has torsional deformation and abuts against the fixing member and the hinge, and there is a second gap between the movable plate and the heat dissipation assembly. The first gap is greater than the second gap, and the second gap is greater than the initial gap. This application also provides a terminal device.
