Abstract
A camera module includes a base, a plurality of guide bars coupled to the base, a first mover disposed in the base, the first mover including at least one lens disposed therein, and a second mover disposed in the base, the second mover including at least one lens disposed therein, wherein each of the first mover and the second mover includes a plurality of guide grooves formed therein to allow the guide bars to be disposed therein, and wherein each of the plurality of guide grooves includes a protruding portion formed to be in contact with a respective one of the guide bars.
Claims20
A camera module, comprising:
- a base;
- four guide bars coupled to the base, each of the guide bars being configured to be stationary;
- a first mover disposed in the base, the first mover comprising at least one lens disposed therein;
- and
- a second mover disposed in the base, the second mover comprising at least one lens disposed therein,
- wherein each of the first mover and the second mover comprises four guide grooves formed therein to allow respective guide bars to be disposed therein, each of the guide grooves being arranged symmetrically with respect to another of the guide grooves that is located on a respective opposite side of the first or second mover in a direction orthogonal to an optical axis,
- wherein each of the guide grooves comprises a protruding portion formed in each of the guide grooves to be in contact with a respective one of the guide bars,
- wherein a plurality of mounting grooves, in each of which a respective one of the guide bars is mounted, are formed in the base in a longitudinal direction of the guide bars, and
- wherein the first mover and the second mover are guided by the guide grooves to move in an optical-axis direction while maintaining sliding contact with the guide bars, and
- wherein each protruding portion is protruded outward in a direction perpendicular to the optical-axis direction from a bottom surface of each of the guide grooves to reduce a contact area between the respective guide groove and the respective guide bar to reduce a contact area between the guide bars and each of the first mover and the second mover.

A camera module, comprising:
- a prism configured to change an optical path;
- and
- a moving unit disposed opposite the prism,
- wherein the moving unit comprises:
- a first lens group disposed adjacent to the prism;
- a second lens group disposed so as to be spaced apart from the first lens group in an optical-axis direction;
- a third lens group disposed between the first lens group and the second lens group and configured to move in the optical-axis direction;
- four guide bars disposed such that a longitudinal direction of respective guide bars is oriented in the optical-axis direction and configured to be in sliding contact with the third lens group to guide movement of the third lens group, each of the guide bars being configured to be stationary;
- and
- a base to which the guide bars are mounted,
- wherein the third lens group comprises a mover, the mover comprising a plurality of guide grooves, each of the guide bars being disposed so as to be in sliding contact with a respective guide groove of the plurality of guide grooves,
- wherein each of the plurality of guide grooves comprises a protruding portion formed in each of the guide grooves to be in contact with a respective one of the guide bars,
- wherein a plurality of mounting grooves in which a respective guide bar of the guide bars is mounted, is formed in the base in a longitudinal direction of the guide bars, and
- wherein the mover is guided by the plurality of guide grooves to move in an optical-axis direction while maintaining sliding contact with the guide bars, and
- wherein the protruding portion is protruded outward in a direction perpendicular to the optical-axis direction from a bottom surface of each of the plurality of guide grooves to reduce a contact area between the guide grooves and the guide bars to reduce a contact area between the guide bars and the mover.
