AI Technical Summary
The existing frame design requires many connected parts and welding connections, resulting in low assembly efficiency. It is also prone to damage in rear-end collisions, and the structural strength and safety are reduced after repair, affecting vehicle safety and resale value.
The design employs a split connection between front and rear aluminum alloy castings, reducing the number of connecting parts, improving assembly efficiency, and allowing for direct replacement of vulnerable parts in the event of an accident, thus maintaining vehicle safety.
It improves vehicle structural strength and assembly efficiency, avoids structural damage caused by accidents that could affect safety and depreciation of used vehicles, and reduces maintenance and economic losses.
