Problems solved by technology

[0003] When the zoom lens zooms, it usually realizes the change of the focal length of the zoom lens through its internal moving group; currently, the moving group in the zoom lens needs to be fixed because the lens needs to be fixed, and the outer diameter of the lens will be set with longer edges before and after, and then reduce The range that the mobile group can move is reduced, the distance that the mobile group can move is small, and the zoom range of the zoom lens is reduced

Abstract

The invention discloses a mobile group, an optical system and a camera device, and relates to the technical field of optics. The device comprises a moving frame, the moving frame is made of a hot melting material, and a lens is arranged in the moving frame; wherein a mounting groove for mounting the lens is formed in the movable frame, and a mounting opening for allowing the lens to enter the mounting groove is formed in at least one end of the movable frame; the end, provided with the installation opening, of the movable frame is used for being bent inwards and is arranged on the lens in a hot melting mode. According to the invention, the thickness of the moving frame at the outer end of the lens is reduced, the moving distance of the moving group is increased, and the focusing range of the moving group is increased.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to a mobile group, an optical system and an imaging device. Background technique [0002] A zoom lens is a camera lens that can change the focal length within a certain range to obtain different wide and narrow field of view angles, images of different sizes and different scene ranges. The zoom lens can change the shooting range by changing the focal length without changing the shooting distance, so it is very beneficial to the composition of the picture. [0003] When the zoom lens zooms, it usually realizes the change of the focal length of the zoom lens through its internal moving group; currently, the moving group in the zoom lens needs to be fixed because the lens needs to be fixed, and the outer diameter of the lens will be set with longer edges before and after, and then reduce The moving range of the moving group is reduced, the moving distance of the moving group is small...
