Battery Restraint Protrusion Recess Adhesive Connection

The connection structure is segmented into protrusion and recess portions that engage with each other, creating mechanical interlocking. This segmentation allows the adhesive agent to be applied only at specific engagement interfaces rather than across entire surfaces, reducing the total adhesive volume exposed to heat and moisture while maintaining connection strength.

The connection system uses a composite approach combining mechanical features (protrusion and recess portions made of structural materials) with adhesive bonding. This composite structure provides both immediate mechanical engagement and supplemental adhesive bonding, where the mechanical features bear the primary load while the adhesive seals and reinforces the connection, reducing reliance on adhesive alone.

The connection interface is segmented into discrete protrusion and recess portions that provide localized mechanical engagement points. This segmentation adds minimal complexity while significantly improving proof stress by creating load-bearing mechanical interlocks that supplement the adhesive bonding, distributing stresses away from the adhesive layers.

The protrusion and recess portions act as intermediary mechanical features between the connected members. These intermediaries provide direct structural engagement that mediates the load transfer between members, reducing the burden on the adhesive agent and preventing adhesive deterioration from becoming the weak point in the connection.
