Damping hinge mechanism and folding type electronic equipment

The utility model provides a damping hinge mechanism. The mechanism comprises a connecting shaft, a torsion spring and a shell, wherein the shell is of a cylindrical structure, and the position of the shell is fixed; the spiral torsion spring is accommodated in the shell, and the connecting shaft is inserted into the shell and penetrates through the torsion spring; the connecting shaft is fixed at the first end of the torsion spring, and the shell is fixed at the second end of the torsion spring; damping grease is arranged in the internal space of the shell; and the connecting shaft can rotate relative to the shell. The damping hinge mechanism can be automatically bounced off, can be used for controlling the bouncing speed, and is simple in structure and small in floor space, so that equipment can be slowly effectively opened in case of limited space, and relatively good user experience is realized. The utility model further provides folding type electronic equipment adopting the damping hinge mechanism.
