Server Connecting Rod Assembly for Chassis Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing server devices with handle type latches face interference issues due to the proximity of adjacent servers, making it difficult to effectively secure them in a chassis, as reducing the latch protrusion compromises the server's fixation.
Innovation Solution
A connecting rod assembly is introduced, comprising a first, second, and third connecting rod, where the third connecting rod is pivoted to protrude from the server's back part and fasten to the chassis, allowing for a longer fastening length without interfering with adjacent servers, enhancing assembly reliability by adjusting the fastening position on a partition plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the protrusion of the handle type latch is maintained, then the server can be effectively fixed in the chassis, but the handle type latch and adjacent servers interfere with each other
Solution Approach 1:
The patent transitions from a conventional handle-type latch to a connecting rod assembly that utilizes the depth dimension of the chassis. By pivoting the connecting rods and extending the fastening action toward the rear of the chassis, the solution moves the fastening operation from a front-facing protrusion to a rearward extension, thereby eliminating interference with adjacent servers while maintaining secure fixation.
Solution Approach 2:
The latch mechanism is segmented into multiple connecting rods (first, second, and third connecting rods) that work together in sequence. The first connecting rod pivots on the front part, the second on the back part, and the third connects them, allowing the fastening action to be distributed across multiple segments that cooperate to secure the server without requiring a single long protruding latch.
2Object-affected harmful factors
If the protrusion of the latch is reduced, then interference with adjacent servers is minimized, but the server is difficult to fix effectually in the chassis
Solution Approach 1:
Instead of reducing the protrusion in the front direction, the patent extends the fastening action in the rear direction by pivoting the connecting rods toward the back of the chassis. This dimensional shift allows the latch mechanism to achieve sufficient fastening length without interfering with adjacent servers positioned at the front.
Solution Approach 2:
The latch mechanism employs dynamic pivoting motion where the first, second, and third connecting rods rotate relative to each other and to the server body. This dynamic action allows the mechanism to achieve full extension of the fastening rod in a controlled sequence, providing sufficient reach without requiring a statically long protruding latch.

AI summary
A server device including a chassis having an accommodating space and an opening, a least one server having a front part and a back part, and at least one connecting rod assembly having a first connecting rod, a second connecting rod, and a third connecting rod. The server may be located in the accommodating space and be drawable from the opening. The first connecting rod is pivoted on the front part of the server. The second connecting rod is pivoted on the back part of the at least one server. An end of the third connecting rod is pivoted on the first connecting rod, and another end of the third connecting rod is pivoted on the second connecting rod. The first connecting rod is rotatable relative to the server to move the third connecting rod, so that the second connecting rod is fastened to the chassis.
