Anti-fatigue vehicle frame structure

By installing diagonal braces and a central brace at both ends of the frame body, and setting up a buffer anti-fatigue cavity and filling buffer components inside, the vibration and deformation problems caused by the frame due to bumps are solved by using multi-layer composite materials to absorb shocks, thus achieving anti-fatigue and shock absorption effects.

AI Technical Summary

Technical Problem

Existing chassis structures are prone to deformation due to significant body vibration caused by bumps during use, necessitating a fatigue-resistant chassis structure to reduce fatigue and vibration.

Method used

Diagonal braces are installed at both ends of the main frame, and intermediate braces are distributed on the inner side. The intermediate braces have a buffer fatigue-resistant cavity, and a filling buffer is installed inside the filling buffer. The filling buffer has a compression damping cavity, which is fixed by screw connection. Multi-layer composite materials and honeycomb structure are used to absorb vibration.

Benefits of technology

It effectively reduces frame fatigue, lowers structural costs, increases frame strength, absorbs shocks, has a simple structure, and is easy to replace.
