AI Technical Summary

Technical Problem

Currently, the opening and closing of the tank cover and pipe cover of the vehicle-mounted LNG cylinders before and after refueling operations requires manual step-by-step operation, which is cumbersome and inefficient, affecting refueling efficiency.

Method used

An easy-to-refill vehicle-mounted LNG cylinder was designed, employing a double-crank slider mechanism and an anti-theft box. The synchronous operation of the plug plate and pipe cover is driven by a rotary shaft, enabling one-time manual opening and closing of the plug plate and pipe cover. Combined with the locking design, it avoids the inconvenience of unlocking and the risk of loss.

Benefits of technology

It improves the efficiency of gas refueling operations, avoids dust accumulation caused by exposed gas pipes, enhances anti-theft security, simplifies the operation process, and reduces the risk of lock loss.
