Lift-Up Camera Module for Long Zoom in Thin Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increase in zoom distance of camera modules in electronic devices leads to an increase in device thickness, which is unfavorable for thinning designs.
Innovation Solution
A movable lifting component with a first driving assembly that rotates relative to a base, allowing the lens assembly to extend or retract, thereby increasing or reducing the zoom distance without significantly impacting the device's thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the zoom distance of the camera module is increased to meet photographing requirements, then the photographing performance is improved, but the thickness of the electronic device increases
Solution Approach 1:
The camera module employs a movable lifting component that can dynamically adjust its position between extended and retracted states. The first lens assembly moves along the optical axis within a movable space, allowing the zoom distance to be extended when needed while maintaining a thin profile when the lifting component is retracted. This dynamic adjustment mechanism resolves the contradiction between achieving long zoom distance and maintaining thin device thickness.
Solution Approach 2:
The patent introduces a lifting component that adds a vertical dimension of movement to the traditional horizontal lens movement. By moving the lens assembly up and down along the optical axis through the lifting mechanism, the system creates additional movable space without increasing the device's lateral dimensions, thereby achieving extended zoom distance while maintaining thin device thickness.
2Length of moving object
If a movable lifting component is added to enable lens extension, then the zoom distance is increased, but the device complexity increases
Solution Approach 1:
The patent combines the lifting mechanism and lens driving mechanism into an integrated first driving assembly. This assembly includes a base, lifting component, and light transmission component that work together as a unified system. By merging these functions into a single integrated structure, the patent reduces the number of separate components and simplifies the overall assembly process, thereby mitigating the increase in device complexity.
Solution Approach 2:
The first driving assembly serves multiple functions: it provides the lifting motion for the lens assembly, drives the lens movement along the optical axis, and manages the movable space creation. This multi-functional design reduces the need for separate mechanisms for each function, thereby reducing overall device complexity while achieving extended zoom distance.

AI summary
An embodiment of this application provides an electronic device with a movable lifting component, including a base, a lifting component, and a first driving assembly, where the base is fastened to a rear cover of a housing of the electronic device, the first driving assembly rotatably matches the base, and the lifting component is sleeved on an inner side of the first driving assembly. The first driving assembly can rotate relative to the base, the first driving assembly drives the lifting component to move in a direction parallel to an optical axis toward the outside of the housing to form an avoidance space, and a first lens assembly can move in the avoidance space. Formation of the avoidance space expands a movable space of the first lens assembly during zooming, so that the first lens assembly has a long zoom distance, and photographing effect is improved. The first driving assembly can further reversely rotate to drive the lifting component back to an original position, thereby reducing or eliminating impact on a thickness of the electronic device. This facilitates thinning of the electronic device, and ensures thinning effect of the electronic device while meeting a requirement of a long zoom distance of the electronic device.
