Description

Electronic devices with rotatable feet

The disclosure below relates to an electronic device having a rotatable foot.

As hardware components of an electronic device, for example, a note PC (personal computer) are miniaturized and battery efficiency is increased, a technology for reducing the thickness of the electronic device is being developed. When the thickness is reduced, the rigidity may be weakened. For example, even when the electronic device is made of a metal material, the rigidity of the thin plate-shaped structure may be weakened. For example, in a notebook PC, a display that is relatively thin compared to the main body requires a more rigid structure.

When the display of the note PC has an approximately 'L' shape, the display may have sufficient rigidity while the note PC may have a thin overall structure. However, in order for the 'L'-shaped display to rotate and open, it is necessary to separate the bottom surface of the note PC from the ground at regular intervals. The note PC may have a foot for blocking direct contact with the display. Even when the display is closed, if the foot has an excessively protruding shape, the overall thickness of the note PC may be increased. On the other hand, when the display is open and the foot does not have a sufficiently protruding shape, there is a possibility that the display may directly contact the ground.

In a state in which the display is closed, a structure in which the foot is kept in close contact with the main body and the foot sufficiently protrudes from the main body in a state in which the display is open is required.
