Abstract

A foldable electronic device includes a first housing part having first magnetic members disposed toward a first inner wall thereof, a second housing part having a second magnetic members disposed toward a second inner wall thereof, at least one hinge connected between the housing parts, and an accessory having third magnetic members disposed toward an attractive wall. In an unfolded state and a transition folded state, the first and third magnetic members are attractive toward each other to hold the accessory on the first housing part. In a fully folded state, the first and second inner walls are close to each other with magnetic attraction of the first and second magnetic members.

Claims (10)

1 . A foldable electronic device, comprising:

a first housing part having a first inner wall and a first outer wall opposite to each other, and a plurality of first magnetic members which are disposed toward said first inner wall;

a second housing part having a second inner wall and a second outer wall opposite to each other, and a plurality of second magnetic members which are disposed toward said second inner wall and respectively correspond with said first magnetic members;

at least one hinge connected between said first housing part and said second housing part to shift said first housing part and said second housing part among an unfolded state, a transition folded state and a fully folded state; and

an accessory having an attractive wall and a non-attractive wall opposite to each other, and a plurality of third magnetic members which are disposed toward said attractive wall and respectively correspond with said first magnetic members;

wherein, in the unfolded state, said first inner wall and said second inner wall face in the same direction, said attractive wall is attached to and faces said first inner wall and said first magnetic members are respectively attractive to said third magnetic members;

wherein, in the transition folded state, said first inner wall and said second inner wall extend parallel to each other, face each other and are spaced apart from each other to accommodate said accessory therebetween, and said first magnetic members are respectively attractive to said third magnetic members to have said attractive wall be positioned on said first housing part toward said first inner wall; and

wherein, in the fully folded state, said first inner wall and said second inner wall are closer to each other and extend parallel to and face each other, and said first magnetic members are respectively attractive to said second magnetic members.

2 . The foldable electronic device of claim 1 , wherein said first magnetic members are disposed adjacent to a peripheral edge of said first inner wall, said second magnetic members are disposed adjacent to a peripheral edge of said second inner wall, and said third magnetic members are disposed adjacent to a peripheral edge of said attractive wall.

3 . The foldable electronic device of claim 2 , wherein, in the transition folded state, a distance between said second magnetic members and said third magnetic members is larger than a distance between said first magnetic members and said third magnetic members.
