Abstract
An exemplary image stabilizer includes an outer housing, an inner housing, an upper cover and a driving assembly. The inner housing is moveably received in the outer housing. The upper cover is fixedly mounted on the inner housing and moveably supported by the outer housing. The driving assembly includes a first magnetic member and a second magnetic member. The first magnetic member is positioned on the inner housing. The second magnetic member is positioned on the outer housing. The driving assembly is configured for driving the inner housing and the upper cover to move relative to the outer housing in a plane substantially perpendicular to a central axis of the outer housing through interaction between the first magnetic member and the second magnetic member.
Claims17
An image stabilizer, comprising:
- an outer housing comprising a first receiving sleeve having an outer circular bottom wall, an outer cylindrical side wall extending substantially perpendicularly from the outer circular bottom wall, and a plurality of first guiding members extending perpendicularly from an upper end surface of the outer cylindrical side wall along a central axis of the outer housing;
- an inner housing moveably received in the outer housing;
- an upper cover fixedly mounted on the inner housing and moveably supported by the outer housing, the upper cover comprising a cover cylindrical side wall, a cover circular bottom wall and a plurality of second guiding members corresponding to the first guiding members, the cover cylindrical side wall extending perpendicularly from the cover circular bottom wall toward the outer circular bottom wall, the second guiding members extending radially from a circumference of the cover circular bottom wall, each of the second guiding members slidably coupled to a corresponding first guiding member, the first guiding members configured for guiding the movement of the inner housing and the upper cover;
- and
- a driving assembly comprising a first magnetic member and a second magnetic member, the first magnetic member positioned on the inner housing, the second magnetic member positioned on the outer housing, the driving assembly configured for driving the inner housing and the upper cover to move relative to the outer housing in a plane substantially perpendicular to the central axis of the outer housing through interaction between the first magnetic member and the second magnetic member.
A camera module, comprising:
- an image stabilizer comprising:
- an outer housing comprising a first receiving sleeve having an outer circular bottom wall, an outer cylindrical side wall extending substantially perpendicularly from the outer circular bottom wall, and a plurality of first guiding members extending perpendicularly from an upper end surface of the outer cylindrical side wall along a central axis of the outer housing;
- an inner housing moveably received in the outer housing;
- an upper cover fixedly mounted on the inner housing and moveably supported by the outer housing, the upper cover comprising a cover cylindrical side wall, a cover circular bottom wall and a plurality of second guiding members corresponding to the first guiding members, the cover cylindrical side wall extending perpendicularly from the cover circular bottom wall toward the outer circular bottom wall, the second guiding members extending radially from a circumference of the cover circular bottom wall, each of the second guiding members slidably coupled to a corresponding first guiding member, the first guiding members configured for guiding the movement of the inner housing and the upper cover;
- and
- a driving assembly comprising a first magnetic member and a second magnetic member, the first magnetic member positioned on the inner housing, the second magnetic member positioned on the outer housing, the driving assembly configured for driving the inner housing and the upper cover to move relative to the outer housing in a plane substantially perpendicular to the central axis of the outer housing through interaction between the first magnetic member and the second magnetic member;
- a lens module received in the upper cover;
- a fixing board fixedly attached to the outer housing;
- and
- an image sensor positioned on the fixing board and received in the outer housing.
