Emergent inflation device for tyre burst prevention

Abstract

The invention belongs to the technical field of vehicle passive safety, and concretely relates to an emergent vehicle tyre inflation device for processing a tyre burst situation. The device comprises a pressure sensor, a tyred air bag, a central controller, an explosive gas generator, a flexible glass fiber tube and a tyre burst alarm. When tyre burst occurs, the explosive gas generator receives an instruction of the central controller, and a pulse electronic igniter ignites electric primer and further ignites gunpowder; a large amount of gases which are generated when the gunpowder is combusted are filtered by a filter screen and enter the tyred air bag through going along the flexible glass fiber tube, the air bag is rapidly inflated to support the vehicle as a temporary tyre; and the tyred air bag which has two layers is characterized in that: the inner layer is an annular inner air bag, and the outer layer comprises four isolated independent air bag chambers. The device of the invention has the advantages of fast inflation speed, large gas amount, high safety and reliability, and the like.

Description

technical field [0001] The patent of the present invention belongs to the technical field of passive safety of automobiles, and is precisely an emergency inflation device for automobile tires used to deal with tire blowouts. Background technique [0002] At present, my country has entered a period of rapid growth of family cars. Tire blowout, fatigue driving and speeding are three important factors leading to traffic accidents, among which tire blowout becomes the primary factor due to its unpredictability and uncontrollability. According to statistics, about 30% of domestic traffic accidents are caused by tire blowouts. When the car is running at high speed, tire failure is the most worrying and most difficult to prevent for all drivers. It is an important reason for sudden traffic accidents and a great threat to the driving safety of the car. Preventing tire blowout has become an important topic for safe driving. The currently used anti-explosion tire technologies mainl...

AI Technical Summary

Problems solved by technology

RSC tire adopts technical measures such as thickened tire inner wall and widened rim convex peak to prevent tire blowout, but its high price and short service life of tires limit its application

Expanded foam type run-flat tires are used in racing cars, the cost is too high to achieve popularization

Due to the limited performance of run-flat tires, such technologies as isolating the airtight layer and inflating the run-flat tire have few practical applications
