AI Technical Summary

Technical Problem

Existing hinge devices in electronic devices, such as notebook PCs, require a stopper mechanism to prevent housings from rotating beyond a predetermined angle, which complicates the design and increases the size of the hinge device.

Method used

A hinge device with a metal plate-shaped member and a resin vertical wall member that includes a stopper projection to limit rotation, allowing the housings to rotate relative to each other while preventing excessive rotation without the need for a separate stopper mechanism, thereby miniaturizing the hinge device.

Benefits of technology

The solution enables the hinge device to be miniaturized while effectively preventing excessive rotation, improving manufacturing efficiency and reducing the risk of damage to the housings, while maintaining structural integrity and enhancing ventilation efficiency.

Abstract

The present invention provides an electronic device that can miniaturize the hinge mechanism while preventing the housing from rotating beyond a predetermined number of rotations. [Solution] The electronic device comprises a first housing, a second housing adjacent to the first housing, and a hinge device that connects the first housing and the second housing so that they can rotate relative to each other. The first housing has a metal plate-shaped member and a resin vertical wall member that rises from the edge of the plate-shaped member and whose outer surface forms the side surface of the first housing. The outer surface of the vertical wall member is provided with a stopper projection that, when the first housing and the second housing are rotated to a predetermined angle, contacts the outer surface of the second housing and stops the relative rotation between the first housing and the second housing.
