An exemplary electronic device includes a main body, a cover, a first magnet, and a second magnet. The cover is rotatably connected to the main body. The first magnet is positioned in the main body. The second magnet is positioned in the cover. A polarity of the first magnet and a polarity of the second magnet are the same, such that a repelling magnetic force is produced when the cover is rotated towards the main body to prevent the cover from striking the main body.
