VCM sensor provided with lightweight base and used for preventing foreign matter from flowing in equipment

Abstract

The invention discloses a VCM sensor provided with a lightweight base and used for preventing a foreign matter from flowing in equipment. The VCM sensor comprises a base unit, a driving part, a fixedpart and a first elastic structure, wherein the top end of the base unit is connected with the bottom end of the driving part; the top end of the driving part is connected with the bottom end of the first elastic structure; and the top end of the first elastic structure is connected with the fixed part. The VCM sensor is simple in structure and reasonable in design, and can effectively prevent theforeign matter from entering the equipment to cause equipment damage.

Description

technical field [0001] The invention relates to the technical field of VCM sensor equipment, in particular to a VCM sensor with a lightweight base to prevent the inflow of foreign matter. Background technique [0002] In recent years, camera modules have been used in mobile communication devices, such as mobile phones, tablet PCs, in applications ranging from laptops to automobiles, medical endoscope capsules and household, cleaning robots, and the demand for these products is also growing steadily, forming the largest The camera module of mobile communication equipment in the market is composed of lens, image sensor and auto focus function embodied as VCM sensor and other components, among which VCM sensor is the basic component necessary to achieve high-quality images, because the pixel is obtained by obtaining the precise focus of the camera , a conventional camera module has difficulty focusing on an object due to difficulty in adjusting a distance between an image senso...

AI Technical Summary

Problems solved by technology

[0004] 1. The structure of the existing VCM sensor is complex, and it is easy to cause foreign matter from the outside to flow into the device, resulting in damage to the VCM sensor inside the device;

[0005] 2. The existing VCM sensor cannot meet the requirements of miniaturization and weight reduction while preventing autofocus errors to improve the quality of captured images and videos
