EV Seat Mounting Structure With Recessed Rail Around Battery Mounts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seat mounting structures in electric vehicles interfere with battery connection parts, leading to installation challenges and potential interference issues.
Innovation Solution
A seat mounting structure that positions the seat support part between battery connection parts, utilizing a first rail that crosses multiple cross members and is received in a recessed groove, with a double-floor structure to ensure wide leg space and avoid interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the seat support part is connected to the side sills and cross members, then the seat mounting structure is stable, but it interferes with the battery connection parts joined to the side sills
Solution Approach 1:
The patent introduces a recessed groove in the floor panel as a new spatial dimension for routing the seat support part. Instead of having the seat support part connect directly to side sills and cross members in the horizontal plane, the recessed groove provides a vertical dimension solution by allowing the seat support part to pass through or be received in the groove, thereby separating the seat mounting path from the battery connection parts in the horizontal plane and eliminating interference while maintaining structural stability
2Ease of operation
If the first rail crosses multiple cross members, then the seat sliding movement is smooth, but the structure complexity increases
Solution Approach 1:
The patent segments the seat support structure into multiple components: the first rail, multiple cross members, and a recessed groove. By dividing the support function across these segmented elements rather than using a single complex structure, the patent achieves smooth seat sliding through the distributed support of multiple cross members while keeping each individual component relatively simple and manageable
3Area of moving object
If the floor is provided with a double-floor structure, then the leg space is wide, but the manufacturing complexity increases
Solution Approach 1:
The recessed groove in the floor panel serves multiple functions simultaneously: it provides structural support for the seat support part, creates the double-floor effect that increases leg space, and acts as a routing channel for the seat support part. By making the groove multi-functional rather than adding separate components for each function, the patent achieves wide leg space while minimizing the increase in manufacturing complexity
