AI Technical Summary
Traditional air suspension airbags are exposed under the chassis and are easily damaged, leading to malfunction, affecting vehicle driving stability and shortening service life.
A structure consisting of a first protective plate and a second protective plate surrounding a closed air spring is designed. Combined with the sliding connection between the sealing ring and the protrusion, it achieves physical isolation and sealing functions, and provides overpressure protection through air pressure monitoring and an automatic exhaust mechanism.
It effectively prevents the airbag from being punctured or penetrated, maintains functional integrity, ensures driving safety, and automatically releases gas in case of overpressure to prevent structural damage, thereby improving service life and stability.
