The invention discloses a rollover-prevention device used when automobile tire burst happens. The device comprises a tire pressure monitoring device, a control device, a gas generator and a rollover-prevention mechanism device. A piston plunger and a piston cylinder surrounding the piston plunger are arranged in the rollover-prevention mechanical device, an upper hanging ring is arranged at the upper end of the piston cylinder, a lower hanging ring is arranged at the lower end of the piston plunger, and a through hole composed of a first round hole and a second round hole is arranged in the two side walls of the piston cylinder. An opening is formed in the bottom of the piston cylinder. A pin and a pin cylinder surrounding the pin are arranged at the opening of the first round hole of the piston cylinder. A pull ring is arranged at one end of the pin. When the tire pressure monitoring device monitors that tire burst happens, the control device sends an ignition instruction to the gas generator, and an upper cavity of the piston cylinder is filled with gas generated by burst. Under the expansion function, the piston plunger quickly moves downwards. By means of cooperation of all the parts, the piston plunger penetrates through the opening in the lower end of the piston cylinder so that the portion, at the tire burst end, of an automobile body can be lifted, automobile rollover is prevented, and running safety of an automobile is improved.
