AI Technical Summary
Technical Problem
Existing automatic fuel tank cap locking solutions suffer from high maintenance costs, difficulty in covering all vehicle models, inaccurate locking torque, and high sensor costs in flammable and explosive environments.
Method used
A torque control mechanism is adopted, which adjusts the locking torque through the multi-ratchet outer ring and the elastic ejector pin. Combined with a dynamic parameter library and a torque-rotation angle regression model, flexible and reliable locking control is achieved.
Benefits of technology
It achieves precise control of locking torque without relying on high-cost sensors, reducing costs, improving reliability and environmental adaptability, and meeting the safety requirements of gas stations.
