Patent number: 9541954Abstract: A portable electronic device includes first and second bodies. The first body includes a guiding rail, a restoring component, a first magnet disposed in the guiding rail, top and bottom surfaces. The guiding rail is connected between the top and bottom surfaces. The restoring component is disposed at one end of the guiding rail close to the top surface. The second body including a second magnet is pivotally connected to the first body for rotating from leaning on the top surface till leaning on the bottom surface. When the second body leans on the top surface, the first magnet is attracted to the second magnet to lean on the restoring component. When the second body leans on the bottom surface, an attraction force between the first and second magnets is greater than a restoring force provided by the restoring component so the second magnet moves toward the bottom surface.Type: GrantFiled: November 12, 2015Date of Patent: January 10, 2017Assignee: Acer IncorporatedInventors: Po-Yi Lee, Yi-Chang Yeh
