AI Technical Summary

Technical Problem

Existing car seat vibration damping platforms have a single vibration damping dimension when dealing with complex driving conditions, which cannot adapt to the multi-condition movement of the vehicle. This causes passengers to experience tilting or pitching discomfort due to inertia. In addition, the transmission structure is complex, occupies a large space, has complex control logic, high energy consumption, and insufficient robustness.

Method used

The system employs a first drive mechanism, a second drive mechanism, a support arm assembly, and a vibration damping mechanism located between the upper and lower platforms. Through four sets of power output terminals, the upper platform can achieve multi-attitude adjustment. Combined with magnetorheological dampers and sensing components, the damping force can be adjusted in real time, enhancing the attitude adjustment capability and damping dynamic adaptability, simplifying the control logic, and reducing energy consumption.

Benefits of technology

It achieves posture compensation for drivers and passengers under complex driving conditions, improves the structural compactness and smoothness of the vibration damping platform, enhances driving comfort and application range, and reduces energy consumption.
