Seat Support Member Adhesive Mounting for Composite Battery Packs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional seat support members cannot be welded to vehicle bodies made of composite materials like carbon fiber, posing a challenge in mounting battery packs securely.
Innovation Solution
A seat support member is connected to a battery pack housing using a structural adhesive, eliminating the need for welding and enhancing structural strength, particularly suitable for vehicles with composite material bodies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If welding is used to connect the seat support member to the vehicle body, then the connection strength is improved, but the method becomes inapplicable to composite material vehicle bodies
Solution Approach 1:
The patent replaces the welding (thermal/mechanical) connection system with an adhesive bonding system. The seat support member is connected to the vehicle body through adhesive bonding rather than welding, which eliminates the incompatibility with composite materials while maintaining connection strength. This substitution allows the same mounting structure to work with both metal and composite vehicle bodies.
2Adaptability or versatility
If structural adhesive is used to connect the seat support member to the battery pack housing, then the adaptability to composite materials is improved, but the connection strength may be reduced
Solution Approach 1:
The patent employs structural adhesive as a bonding material that creates a composite connection system. The adhesive layer acts as an intermediate composite material between the seat support member and the battery pack housing, distributing stresses and providing both chemical bonding and mechanical interlocking. This composite approach maintains strength while enabling compatibility with various materials including composites.
Solution Approach 2:
The structural adhesive serves as an intermediary substance between the seat support member and the battery pack housing. It mediates the connection by providing a bonding interface that accommodates different materials (metal and composite), distributes loads, and compensates for dimensional variations, thereby maintaining connection strength across material boundaries.
3Ease of manufacture
If the seat support member is welded to the vehicle body, then the manufacturing process is simple, but the method cannot be used with composite material vehicle bodies
Solution Approach 1:
The patent substitutes the welding manufacturing process with adhesive bonding. This replacement eliminates the complexity of welding operations (positioning, heat control, skill requirements) while maintaining manufacturing simplicity through straightforward adhesive application and curing processes, making the method universally applicable to both metal and composite vehicle bodies.

AI summary
This application discloses a seat support member mounting structure, a battery pack, and a vehicle. The seat support member mounting structure includes a seat support member and a battery pack housing. The seat support member is connected to the battery pack housing by using a structural adhesive. According to the solutions of this application, the seat support member does not need to be welded to a vehicle body, and safety of the battery pack during collision can be improved. Therefore, the seat support member is particularly suitable for the vehicle body manufactured by using a composite material.
