Embodiment Construction

[0030] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0031] In this disclosure, unless stated to the contrary, the orientation words used such as "front and rear" are defined based on the camera module. It is considered that the orientation facing the lens during use is the front, and the opposite direction is the rear. It is located in the axial direction, and in addition, in the drawings provided in this disclosure, the "front, rear" orientation corresponds to Figure 1 to Figure 4 The upper and lower positions in the drawing. In addition, "inner and outer" are "inner and outer" with respect to the outline of the corresponding component itself. In addition, the terms "first, second, third" and the like used...

Abstract

The invention relates to a filtering zoom assembly, a camera module and a terminal. The filtering and zooming assembly comprises a zooming unit (10), a filtering element (20) and an annular installation support (30). The mounting bracket (30) is provided with a first end (301) and a second end (302) which are opposite to each other along the axial direction. The zoom unit (10) and the filter element (20) are sequentially arranged in the axial direction from the first end (301) to the second end (302) and are kept in the mounting bracket (30), and the second end (302) is provided with a fixingpart suitable for being connected with the front end of a lens (40). According to the technical scheme, the filtering and zooming assembly provided by the invention has zooming and cut-off filtering functions, so that dust particles and other dirt are effectively prevented from being introduced in the process that the filtering element is independently assembled to the camera module, and the rateof finished products of the camera module is improved.

Description

technical field [0001] The present disclosure relates to the technical field of camera modules, and in particular, to a filter zoom assembly, a camera module and a terminal. Background technique [0002] Existing camera modules usually have a built-in cut-off filter, and the cut-off filter is placed close to the imaging sensor to filter out wave bands that are likely to cause signal crosstalk to the image sensor. However, during the assembly process of the cut-off filter and the imaging sensor, it is often easy to introduce dirt such as dust particles, resulting in a decrease in the yield of the camera module. Contents of the invention [0003] The purpose of the present disclosure is to provide a filter zoom assembly, which can have both zoom and cut-off filter functions, and effectively prevent dust particles and other dirt from being introduced into the process of independently assembling the filter element into the camera module. pollution, thereby improving the yield...
