PCIe Card Module Rotating Lock for Tool-Free Server Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for mounting and removing PCIE add-in card modules in servers are inconvenient, requiring tools like screwdrivers, prone to damage, and suffer from unstable fixing and high costs, with stop pieces easily falling off during vibration.
Innovation Solution
A PCIE card module mechanism featuring a frame body, locking member, and rotating handle with a locking structure, allowing tool-less mounting and removal by rotating the handle to align and lock the frame body onto the chassis, utilizing a locking fit between the handle and locking member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a screw fixing structure is used to mount the PCIE add-in card module, then the fixing is firm and stable, but tools like screwdrivers are required making the operation inconvenient and time-consuming
Solution Approach 1:
The patent replaces the traditional screw-based mechanical fastening system with a rotating handle locking mechanism. The rotating handle engages with locking members through a locking structure, eliminating the need for screwdrivers and traditional screw fastening while achieving firm fixation of the PCIE add-in card module.
Solution Approach 2:
The rotating handle mechanism allows users to mount and remove the PCIE add-in card module directly without external tools. The locking structure on the rotating handle automatically engages with the locking members when the handle is rotated to the locking position, enabling tool-free operation.
2Productivity
If a screw fixing structure is used to mount the PCIE add-in card module, then the fixing is firm and stable, but the operation efficiency is low due to tool requirements
Solution Approach 1:
The patent replaces the traditional screw-based mechanical fastening system with a rotating handle locking mechanism. The rotating handle engages with locking members through a locking structure, eliminating the need for screwdrivers and traditional screw fastening while achieving firm fixation of the PCIE add-in card module.
Solution Approach 2:
The rotating handle mechanism allows users to mount and remove the PCIE add-in card module directly without external tools. The locking structure on the rotating handle automatically engages with the locking members when the handle is rotated to the locking position, enabling tool-free operation.
3Ease of operation
If a single-sided fixing and locking method is used, then tool-free operation is achieved, but the other side is prone to warping leading to unfirm fixing
Solution Approach 1:
The patent divides the locking function into multiple independent locking members distributed at different positions (front and rear sides) of the PCIE add-in card module. Each locking member works independently through its own locking structure on the rotating handle, ensuring that fixing on one side does not compromise the other side, preventing warping issues.
Solution Approach 2:
The locking members are asymmetrically distributed at different positions on the frame body, with at least one locking member on the front side and at least one on the rear side. This asymmetric distribution ensures balanced fixation and prevents warping that would occur with single-sided fixing.
4Reliability
If traditional stop pieces are used for empty PCIE card slots, then the slots are blocked, but the stop pieces are not fixed firmly and easily fall off during vibration
Solution Approach 1:
The patent merges the stop piece function with the locking member system. The locking members serve dual purposes: they lock the PCIE add-in card module when components are installed, and they secure the stop pieces in empty slots. This integration eliminates the need for separate fixing mechanisms for stop pieces.
Solution Approach 2:
The patent replaces traditional separate stop piece fixing mechanisms with the rotating handle locking system. The locking structures on the rotating handle engage with locking members that can secure both active PCIE cards and passive stop pieces, providing firm fixation that prevents falling during vibration.

AI summary
The present disclosure provides a PCIE card module mechanism and a server. The PCIE card module mechanism includes: a frame body detachably mounted inside a chassis; a locking member connected to the chassis, the frame body is butted with the locking member when mounted inside the chassis; and a rotating handle. The rotating handle is rotatably connected to the frame body and has a locking position and an unlocking position, the rotating handle further is provided with a locking structure that is in locking fit with the locking member; when the rotating handle is located in the locking position, the locking structure and the locking member are in locking fit and lock the frame body onto the chassis; when the rotating handle is located in the unlocking position, the locking structure and the locking member are separated, and the frame body is able to be removed from the chassis.
