Tyre pressure monitoring based blow-out emergency inflation system

Abstract

The invention discloses a tyre pressure monitoring based blow-out emergency inflation system which comprises a sensor, a controller, a gas generator, a gas generation chamber, an airflow channel and a vacuum tube tyre, wherein the sensor is used for monitoring the pressure state of a tyre and transmitting a blow-out signal to the controller; the controller transmits an instrument to ensure that the gas generator generates a great quantity of gas, and the gas is conveyed into the vacuum tube tyre for inflating through the airflow channel. Under the normal state, the vacuum tube tyre can be used as a vacuum tyre or a tube tyre; after the tyre blows out, the gas generator ignites to release gas, and the gas enters a space between a steel ring and the half side in the vacuum tube tyre through the airflow channel; and the inner half side can be jacked upwards due to the gas pressure difference and the centrifugal force so as to be closely clung to the outer half side to form a double-layer vacuum tyre, therefore, the tyre can be ensured not to leak air and a vehicle can be ensured to run normally.

Description

technical field [0001] The invention belongs to the field of automobile components, and relates to the treatment of tire blowouts of automobile tires, in particular to an emergency inflation system for tire blowouts based on tire pressure monitoring. Background technique [0002] According to a 2002 survey conducted by the Society of Automotive Engineers, an average of 260,000 traffic accidents in the United States are caused by low tire pressure or leakage; 70% of traffic accidents on highways are caused by burst tires; in addition, 75% of tire failures each year are due to leaking or underinflated tires. Statistics show that: the main cause of traffic accident increase is the blowout caused by tire failure in high-speed driving. In China, statistics show that 46% of traffic accidents on expressways are caused by tire failures, and tire blowouts account for more than 70% of the total accidents, most of which are caused by car owners. Caused by improper maintenance of tire...

Secondly, due to the high cost, BMBS has not been popularized in family cars, but only in a very small number of luxury models.

In addition, the solid tires that exist now, or tires filled with foam fillers, although they can avoid air leakage, they are less comfortable

There is another method, which is to increase the radius of the rim to reduce the drop after a tire blowout without causing too much impact. Improve the overall shock absorption of the vehicle under the premise
