Multi-group lens, camera module and electronic equipment

Abstract

The present application relates to a multi-group lens, a camera module and an electronic device, the multi-group lens comprising: a plurality of group units, the group unit, close to the object side, of two adjacent group units being an upper group unit, and the group unit, close to the image side, of two adjacent group units being a lower group unit; the upper group unit comprises an upper lens group and an upper bearing part, and the upper lens group is arranged on the upper bearing part; the lower group unit comprises a lower lens group and a lower bearing part; the lower bearing part comprises a lower bearing main body, and the lower lens group is arranged on the lower bearing main body; the lower inner extending part extends inwards from the lower bearing main body; the lower lap joint part is arranged on the lower bearing main body; the lower lap joint part is connected with the upper bearing part, and the lower inner extension part is restrained by the upper group unit. The device is simple and convenient to assemble and adjust, and has the excellent performance of high imaging pixel, small TTL and the like with high user experience.

Description

[0001] This application is a divisional application. The invention name of the original application is "a multi-group lens, camera module and its assembly method, and electronic equipment", the application number is 201880027359.4, and the application date is June 14, 2018. technical field [0002] The present application relates to the technical field of optical equipment, in particular to a multi-group lens, a camera module and electronic equipment. Background technique [0003] The lens is an important part of the camera module, which directly affects the imaging quality of the camera module. [0004] In traditional optical lenses, multiple lenses are assembled in the same lens barrel, and the relative positions of the lenses are basically fixed and cannot be adjusted. Once the lens is assembled in the lens barrel, the quality of the lens is determined, which also requires higher processing accuracy for the lens barrel and lens. The optical lens is an independently assem...

Problems solved by technology

The application for the invention improves the precision of the glass from the manufacturing technology, but when it is subsequently assembled and used on the lens, such as when it is used in combination with resin glass or glass-resin composite glass, the precision of each lens itself and the precision of each lens, as well as the packaging The precision issue remains unresolved
