Intelligent car buffer air bag

The invention relates to an intelligent car buffer air bag. A plurality of buffer air bags are fixed on a buffer air bag rigid frame. A light plastic panel is fastened to the buffer air bag rigid frame and wraps the buffer air bags. A range finder and a speed instrument respectively collects a distance signal and a speed signal which are transmitted to an automatic identification system. The automatic identification system outputs control signal to a buffer air bag ignition circuit. The buffer air bag ignition circuit ignites to allow a solid gas generator to operate so as to open the buffer air bags. The buffer air bags are cylindrical when opened. The cylindrical buffer air bags push away the light plastic panel. A shape-preserving ring is disposed at the top end of each cylindrical air bag. The intelligent car buffer air bag has the advantages that composite materials are fully utilized and easy to obtain; the intelligent car buffer air bag are high in strength, safe to use and capable of effectively prote
