Abstract

The invention provides an adjustable optical assembly. The adjustable optical assembly comprises a bearing base, a driving mechanism, a zoom optical assembly and a compensation optical assembly. The driving mechanism comprises the following components of: a support of which the bottom end of the support is connected with the bearing base, and of which the top end is provided with a top groove with an upward opening; a guide rod which is erected in the top groove, the direction of the optical axis of the guide rod being consistent with that of the optical axis of the zoom optical assembly and that of the optical axis of the compensation optical assembly; a zoom carrier; a compensation carrier; a zoom driving assembly; and a compensation drive assembly. The zoom carrier and the compensation carrier are both installed on the guide rod and can slide along the guide rod. The invention also provides a corresponding periscopic optical zoom module. According to the adjustable optical assembly, the support and the guide rod are arranged on the bearing base, and it can be effectively guaranteed that the moving directions of a zoom group and a compensation group do not deviate from the main optical axis; and meanwhile, the adjustable optical assembly is compact in structure and convenient to assemble, and large-scale mass production is facilitated.

Description

technical field [0001] The invention relates to the technical field of camera modules, in particular, the invention relates to a periscope optical zoom module. Background technique [0002] With the improvement of living standards, consumers have higher and higher requirements for camera functions of terminal devices such as mobile phones and tablets. They not only require effects such as background blur and night shooting, but also demand telephoto. Terminal equipment that captures distant images clearly. [0003] In order to achieve shooting at different distances, the current terminal equipment on the market realizes zoom shooting by using a wide-angle lens + a telephoto lens to form an array module. However, since the lens is usually a fixed-focus lens, its focal length cannot be adjusted. The intercepted images are digitally zoomed by algorithms such as difference, and the imaging quality of the pictures is poor. Even if some terminal devices use lenses with AF (Auto F...
