Abstract
The shutter device includes a base, a post, a coil, a shutter, a first magnetic member, and a second magnetic member. The base defines a first aperture. The post is fixedly mounted on the base. The coil is connected to the post and rotatable around the post. The shutter blade is coupled to the post and jointly rotatable with the coil. The first and second magnetic members are mounted on the base arranged on two sides of the coil. The first and second magnetic members are configured for driving the coil to rotate, thereby moving the shutter blade to selectively expose or cover the first aperture.
Claims18
A shutter device, comprising:
- a support comprising a base, three protrusions, and a buffer, the base being substantially square-shaped and comprising a supporting surface, a first side, a second side, a third side parallel to the first side, and a fourth side parallel to the second side, the base defining a first aperture therein, a recess adjacent to the first side, and a slot communicating the recess and the first aperture, the protrusions extending from the supporting surface and positioned at three corners of the base, the buffer fixed on a bottom surface in the recess and suspended in the slot;
- a rotating member positioned at the remaining corner of the base and comprising a post fixedly mounted on the base;
- a coil connected to the post and rotatable around the post;
- a shutter blade coupled to the post and jointly rotatable with the coil;
- and
- a first magnetic member and a second magnetic member mounted on the base and arranged on two sides of the coil, the first and second magnetic members configured for driving the coil to rotate, thereby moving the shutter blade to selectively expose or cover the first aperture.

A shutter device comprising:
- a support comprising a base, three protrusions, and a buffer, the base being substantially square-shaped and comprising a supporting surface, a first side, a second side, a third side parallel to the first side, and a fourth side parallel to the second side, the base defining a first through hole, a recess adjacent to the first side, and a slot communicating the recess and the first through hole, the protrusions extending from the supporting surface and positioned at three corners of the base, the buffer fixed on a bottom surface in the recess and suspended in the slot;
- a cover defining a second through hole aligned with the first through hole, the first and second through holes cooperatively defining a light passage;
- a rotating member positioned at the remaining corner of the base and comprising a post arranged between the base and the cover;
- a shutter blade rotatably coupled to the post;
- a coil fixedly coupled to the shutter blade;
- a first permanent magnet and a second permanent magnet mounted on the base and arranged on two sides of the coil, the first and second permanent magnets configured for applying a combined magnetic force to the coil to drive the coil to rotate, thereby moving the shutter blade to selectively close or open the light passage;
- and a driving circuit configured for controlling directions and intensity of the electric current flowing in the coil.
