AI Technical Summary

Technical Problem

Existing camera modules are prone to deviation during the long-distance expansion and contraction of the lens, resulting in unstable motion and affecting imaging quality. Electromagnetic drive will cause magnetic interference to other components, making the assembly complex.

Method used

The imaging module design includes a base, an ejector and an elastic member. The ejector is cooperated with the guide groove through a slider, and the elastic force of the elastic member drives the ejector to move in the axial direction to ensure that the expansion and contraction direction is consistent with the optical axis direction and avoid deviation.

Benefits of technology

It realizes that the camera module does not cause deviation after popping up, has reliable power, is simple to assemble, and does not interfere with other components, improving imaging quality and user experience.

Abstract

The present disclosure relates to a camera module and an electronic device, wherein the camera module includes a base, a pop-up portion that can move relative to the base and pop up the housing of the electronic device, and an elastic member arranged between the base and the pop-up portion, wherein the base surrounds the pop-up portion, and the inner circumference of the base is provided with a guide groove extending in the axial direction; the pop-up portion includes a main body and a sliding member radially protruding from the outer circumference of the main body, and the sliding member slides into the guide groove; the pop-up portion has a retracted position and a pop-up position, and the elastic member has an elastic force for driving the pop-up portion to move from the retracted position to the pop-up position. Through the above technical solution, the camera module is easy to assemble and has reliable power, and can ensure that the pop-up portion will not be offset after being ejected, and will not interfere with other components.
