Vehicle Swing Door Mounting Structure for Roof-Side Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle designs face challenges in securing the rigidity and mounting stability of swing doors, particularly in purpose-built vehicles (PBVs) with wide indoor spaces, which can compromise the vehicle's overall structural integrity and performance.
Innovation Solution
A swing door mounting structure for vehicles that includes a roof side reinforcement member, door mounting member, and additional reinforcement elements such as center bulk head and roof rails, which are coupled to form a robust structure to secure the swing door's mounting and enhance the vehicle's rigidity and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a swing door is mounted on a PBV with wide indoor space, then user accessibility is improved, but door mounting rigidity deteriorates
Solution Approach 1:
The door mounting structure is divided into multiple components: roof side upper member, roof side reinforcement member, door mounting member, and fastening members. This segmentation allows each component to be optimized for its specific function while collectively providing the necessary mounting rigidity for swing doors in PBVs
Solution Approach 2:
The roof side reinforcement member extends in the vehicle front-rear direction, adding a longitudinal dimension to the mounting structure. This dimensional extension distributes mounting loads across a larger area of the vehicle body, improving door mounting rigidity without compromising user accessibility
2Strength
If swing door mounting structure is added to enhance mounting stability, then door mounting rigidity is improved, but vehicle body complexity increases
Solution Approach 1:
The roof side reinforcement member serves multiple functions: it reinforces the roof side structure, provides mounting points for swing doors, and enhances overall vehicle body rigidity. This multi-functionality reduces the need for separate components, thereby limiting the increase in vehicle body complexity
Solution Approach 2:
The door mounting member is integrated with the roof side reinforcement member and roof side inner panel, merging multiple structural elements into a unified mounting system. This integration simplifies the overall vehicle body structure while maintaining improved door mounting rigidity
3Strength
If additional reinforcement members are coupled to form robust structure, then vehicle body rigidity is improved, but manufacturing complexity increases
Solution Approach 1:
The roof side reinforcement member is designed with pre-formed coupling positions and attachment structures that align with corresponding components. This preliminary design of coupling interfaces simplifies the assembly process and reduces manufacturing complexity while achieving improved vehicle body rigidity
