AI Technical Summary

Technical Problem

Foldable electronic devices face operational reliability issues due to the difficulty in securing space for surrounding structures caused by the rotation radius of support plates, leading to malfunctions or jamming during frequent folding operations.

Method used

Incorporating a center plate with a guide damper and protrusions within the hinge device, which moves uniformly through interlocking engagement with rotating members, allowing for efficient assembly and improved operational reliability by reducing the rotation radius and preventing interlocking deviations.

Benefits of technology

Enhances the operational reliability of foldable electronic devices by ensuring smooth and uniform movement of the center plate, reducing the risk of malfunctions and jamming, and improving the assembly and placement of surrounding structures.

Abstract

According to various embodiments, an electronic device may comprise: a first support plate (311) coupled to a hinge device (320, 320-1) in an area corresponding to a first housing (110); a second support plate (312) coupled to the hinge device (320, 320-1) in an area corresponding to a second housing (120); a first rotation member (3217) including a first protrusion (3217a) formed at a position spaced apart from a first rotation axis (X1); a second rotation member (3218) including a second protrusion (3218a) formed at a position spaced apart from a second rotation axis (X2); and a center plate (313) disposed between the first support plate (311) and the second support plate (312) and including a first engagement portion (3132a) interlocked with the first protrusion (3217a) and a second engagement portion (3132b) interlocked with the second protrusion (3217b), wherein the center plate (313) is moved through the engagement and interlocking of the first and second engagement portions (3132a, 3132b) with the first and second protrusions (3217a, 3217b), respectively, when a foldable housing moves from an unfolded position to a folded position.
