Portable electronic device and movable lens-shutting module thereof

A movable lens-shutting module, comprising:

• a magnetic field generator;
• a rotatable driving assembly including a rotatable magnetic element adjacent to the magnetic field generator and a rotatable driving element fixed on the rotatable magnetic element, wherein the rotatable driving element includes at least one driving rod;
• and
• a movable shutter assembly including at least one shutter element, wherein the at least one shutter element includes a lens opening corresponding to a lens and a receiving groove for receiving the at least one driving rod;
• wherein when the rotatable magnetic element and the rotatable driving element are concurrently moved by a magnetic force generated by the magnetic field generator, the at least one shutter element is moved in a linear direction by moving the at least one driving rod, so that the lens is exposed by the lens opening or is blocked by the at least one shutter element;
• wherein the rotatable driving element includes a position-limiting portion, and the position-limiting portion has a curved guiding groove for movably receiving an elastic stopper, so that a rotating angle of the rotatable driving element is restricted by the elastic stopper.

A portable electronic device comprising an image-capturing assembly that includes an image-capturing module and a movable lens-shutting module, the image-capturing module including a lens mated with the movable lens-shutting module, and the movable lens-shutting module comprising:

• a magnetic field generator;
• a rotatable driving assembly including a rotatable magnetic element adjacent to the magnetic field generator and a rotatable driving element fixed on the rotatable magnetic element, wherein the rotatable driving element includes a first driving rod and a second driving rod;
• and
• a movable shutter assembly including a first shutter element and a second shutter element overlapping with each other, wherein the first shutter element includes a first lens opening corresponding to the lens and a first receiving groove for receiving the first driving rod, and the second shutter element includes a second lens opening corresponding to the first lens opening and a second receiving groove for receiving the second driving rod;
• wherein when the rotatable magnetic element and the rotatable driving element are concurrently moved by a magnetic force generated by the magnetic field generator, the first shutter element and the second shutter element are respectively moved in two different directions by respectively moving the first driving rod and the second driving rod, so that the first lens opening and the second lens opening are in a strictly overlapping relationship with each other so as to expose the lens by the first lens opening and the second lens opening, or the first lens opening and the second lens opening are not in a strictly overlapping relationship with each other so as to cover the lens by the movable shutter assembly;
• wherein the rotatable driving element includes a position-limiting portion, and the position-limiting portion has a curved guiding groove for movably receiving an elastic stopper, so that a rotating angle of the rotatable driving element is restricted by the elastic stopper.
