Abstract
A hinge assembly (20) including a first magnetic member (21) and a second magnetic member (22) is described. The polarities of opposing end surfaces of the first magnetic member and the second member are different. The second magnetic member is configured for rotating relative to the first magnetic member to generate a magnetic moment. In addition, an exemplary portable electronic device (100) equipped with the hinge assembly is also described.
Claims12
A portable electronic device, comprising:
- a body comprising a first hinge receiving portion having a first receiving slot;
- a cover coupled with the body by a hinge assembly, the cover comprising a second hinge receiving portion having a second receiving slot;
- the hinge assembly includes a first magnetic member having a first end surface, and a separate second magnetic member aligned with the first magnetic member and having a second end surface opposite to the first end surface, wherein the polarity of the first end surface is opposite to the polarity of the second end surface;
- and
- the first magnetic member is totally embedded in the first receiving slot, the second magnetic member is totally embedded in the second receiving slot, and when the second magnetic member rotates relative to the first magnetic member until the first end surface and the second end surface are askew, a magnetic moment is generated between the first end surface and the second end surface to further rotate the second magnetic member relative to the first magnetic member.
