AI Technical Summary

⚠Technical Problem

Existing automotive seatbelt testing devices are prone to ejection when the seatbelt breaks during high-load tensile testing, posing a safety hazard. Furthermore, the testing environment cannot simulate different climatic conditions, affecting the accuracy of the test.

⚗Method used

A car seat belt testing device with a protective mechanism was designed, including a protective frame, a buffer detection layer, a micro switch, a heating device, and a humidification device. The protective frame prevents the seat belt from breaking and popping out, buffers the impact force, and uses a temperature and humidity detector and a simulation mechanism to simulate different climatic conditions, thereby improving the safety and accuracy of the test.

🎯Benefits of technology

It effectively prevents injury to workers from broken seat belts, improves testing safety, and can simulate testing environments under different climatic conditions, thereby improving testing accuracy.
