Integrated Lower Vehicle Body Frame Assembly for Collision Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vehicle body frame assemblies, particularly in electric vehicles, suffer from weak structural integrity during collisions due to a split-type design of main longitudinal and cross beams, leading to deformation and compromised safety performance.
Innovation Solution
An integrally formed lower vehicle body frame assembly comprising a frame body, footrest plate, and rear cross beam, which enhances structural stability and resistance to impact forces by distributing load more effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a split-type design of main longitudinal and cross beams is used, then the device complexity is reduced and ease of manufacture is improved, but the strength and structural integrity deteriorate during collisions
Solution Approach 1:
The patent merges the frame body, footrest plate, and rear cross beam into an integrally formed lower vehicle body frame assembly. This combining of previously separate components into a single integrated structure enhances structural integrity and collision resistance while eliminating the need for complex assembly processes, thereby resolving the contradiction between ease of manufacture and structural strength.
2Stability of the object's composition
If an integrally formed structure is used, then the strength and stability are improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The integrally formed lower vehicle body frame assembly performs multiple functions simultaneously: it provides structural support, serves as a mounting platform for the footrest plate, incorporates the rear cross beam for additional stability, and acts as a collision-resistant structure. This multi-functionality reduces the number of separate components needed, thereby simplifying the overall device complexity while maintaining high structural stability.
3Reliability
If an integrally formed structure is used, then the reliability during collisions is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The patent employs parameter changes in the form of integrated molding parameters and material properties to achieve high reliability. By controlling the integration parameters during manufacturing and selecting appropriate materials with suitable mechanical properties, the assembly achieves enhanced collision reliability without requiring excessively tight tolerances on individual features, thus managing manufacturing precision requirements.
