Flexible Busbar Connects Electric Drive Terminals

The patent applies the dynamics principle by introducing a flexible busbar design that can dynamically adapt to thermal expansion and tolerance effects. The flexible busbar replaces the completely rigid structure with one that has controlled flexibility, allowing it to bend and accommodate dimensional changes while maintaining electrical connection, thus resolving the contradiction between manufacturing simplicity and adaptability.

The patent applies parameter changes by modifying the mechanical properties of the busbar from completely rigid to flexibly rigid. This is achieved by changing the geometric parameters of the busbar (such as cross-sectional shape, thickness distribution, or introducing bends) to create a structure with appropriate flexibility, allowing it to adapt to thermal expansion while maintaining structural integrity and electrical conductivity.

The patent applies the local quality principle by making only specific portions of the busbar flexible rather than the entire connection system. The flexible sections are localized at critical points where thermal expansion occurs, while other portions remain rigid for structural stability. This selective flexibility reduces manufacturing cost compared to using completely flexible cables throughout the entire system.

The patent applies composite materials by creating a hybrid busbar structure that combines rigid and flexible characteristics within a single component. This composite design integrates sections with different mechanical properties - rigid sections for structural support and flexible sections for adaptation - thereby achieving the benefits of both rigid and flexible connections while avoiding the cost of complete cable assemblies.

The patent applies dynamics by designing the busbar with controlled flexibility that allows it to dynamically respond to thermal expansion forces. The flexible busbar can bend and deform elastically under expansion stresses, absorbing the mechanical energy that would otherwise cause damage to rigid connections or surrounding components, thus maintaining both structural stability and reliability.

The patent applies beforehand cushioning by designing the flexible busbar to preemptively absorb thermal expansion stresses before they can cause damage to the electrical terminals or surrounding structures. The flexible sections act as mechanical cushions that deform under expansion forces, protecting the rigid electrical connections from stress concentration and potential failure.
