Electronic device including hinge module

Abstract

According to various embodiments of the disclosure, an electronic device may includes: a first housing in which a display module is disposed; a second housing in which a circuit board and a cooling fan connected to the circuit board are accommodated, where a first opening is defined in the second housing to introduce air into the cooling fan; and a hinge module rotatably connected to the first housing and the second housing, and disposed adjacent to the first opening. The hinge module may includes: a hinge housing in which a first hinge opening is defined to be connected to the first opening; a first main gear disposed in the hinge housing and operably connected to the first housing; a second main gear operably connected to the second housing and configured to rotate in correspondence with the first main gear; a driving gear disposed adjacent to at least one of the first main gear or the second main gear and rotatable in correspondence with at least one of the first main gear or the second main gear; and a first cover plate disposed in the hinge housing and including a first rack gear area which meshes with the driving gear. The electronic device may be switchable between a closed state in which an angle formed by the first housing and the second housing is less than a predetermined angle and an open state in which the angle formed by the first housing and the second housing is equal to or greater than the predetermined angle. When the electronic device is in the closed state, the first cover plate is disposed to overlap with at least part of the first hinge opening. When the electronic device is in the open state, the first cover plate may be spaced apart from the first hinge opening, and the first hinge opening may be opened.
