AI Technical Summary

Technical Problem

Conventional metal transmission casings for electric vehicles are heavy, increasing the overall weight and cost of the vehicle, while also being difficult to handle and assemble, due to their rigid construction.

Method used

A modular transmission casing design comprising a first metal member and a second member made of multiple plastic parts, including a first part, a second part, and a third part, assembled using snap fit locking mechanisms, which reduces weight and cost by allowing for easier manufacturing, transportation, and assembly, and incorporates light emitting diodes for aesthetic appeal and safety alerts.

Benefits of technology

The modular design significantly reduces the weight and cost of the transmission casing, enhances aesthetic appeal, simplifies assembly and maintenance, and provides a safer riding experience through speed-indicated lighting, while maintaining structural integrity and vibration resistance.
