Solution Overview
Problem
Elevating-type camera modules in electronic devices suffer from poor buffering smoothness, leading to issues such as stuttering and failure, which can result in damage during scenarios like falling and pressing.
Innovation Solution
An elevating apparatus with an integrally formed rotating member and elevating member, guided by linkage and elastic members, ensures smooth movement and reliable buffering through precise and coarse positioning, enhanced assembly strength, and elastic extension/compression, reducing damage and improving impact resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the camera module is designed as an elevating structure to increase optical available space, then photographing quality is improved, but buffering smoothness deteriorates and reliability worsens in pressing and falling scenarios
Solution Approach 1:
The patent introduces an elastic member (spring) that is pre-installed between the linkage member and the rotating member to provide beforehand cushioning. When pressing or falling occurs, the elastic member compresses to absorb impact energy, preventing direct transmission of shock to the elevating member and camera module, thus improving buffering smoothness and reliability while maintaining the elevating structure's optical space
Solution Approach 2:
The patent introduces a guide member as an intermediary component between the linkage member and the rotating member. The guide member constrains the linkage member's movement trajectory, ensuring it moves along a predetermined path. This intermediary structure prevents abnormal movement and scratching during impact, improving buffering smoothness without affecting the elevating function's optical space
2Ease of manufacture
If multiple separate components are used for the rotating member and elevating member, then assembly and disassembly are facilitated, but device complexity increases and thinness is compromised
Solution Approach 1:
The patent merges the rotating member and elevating member into an integrally formed single component, eliminating the need for separate assembly and disassembly of these two parts. This integration reduces the total component count and simplifies the overall structure, enabling thinner device design while maintaining ease of manufacture through integral forming processes

Function Achieved in This Case
The solution provides highly reliable buffering, preventing damage and stuttering, ensuring smooth operation and thinness by maintaining the camera module's optical space while resisting external forces.
Implementation Method 1
elastic extension and compression of the elastic member can be good for buffering, thereby reducing or avoiding damage to the elevating member, the rotating member, and the like

AI summary
An elevating apparatus, a camera module, and an electronic device are provided. A rotating member of the elevating apparatus cooperates with an elevating member via a linkage member, and the rotating member rotates to drive, via the linkage member, the elevating member to move up and down in a thickness direction. There is an elastic member between the linkage member and the rotating member or the elevating member. The linkage member is sleeved on at least two guide members, the elastic member is also located on the guide member, and the guide member guides movement of the elastic member and the linkage member, so that the linkage member slides only in the thickness direction. The linkage member, the guide members, and the elastic member are assembled in an accommodation space enclosed by a main body portion and a mounting portion that are integrally formed.
