ROTATING SHAFT MECHANISM AND TERMINAL DEVICE

Embodiments of this application relate to the technical field of terminal devices, and provide a rotating shaft mechanism and a terminal device. The rotating shaft mechanism includes a base, a swing arm, a connection assembly, and a shaft cover. The shaft cover is provided with an accommodating space, at least part of the base is arranged in the accommodating space, and the swing arm is rotatably connected to the base, so that the swing arm is rotatable between an unfolded position and a folded position relative to the base. The connection assembly is connected between the swing arm and the shaft cover, and the swing arm may drive the shaft cover to move toward the base through the connection assembly during rotation of the swing arm from the unfolded position to the folded position. This application may be applied to a terminal device such as a mobile phone.
