Problems solved by technology

[0004] The purpose of the present invention is to solve the technical problem by providing a technical solution that solves the problems of fatal failure without leakage, long-term contact pressure fatigue of sensitive components and switches, and air pollution inside the tire; it can realize the small size of the tire burst sensor and increase the weight by no more than 3 grams, the sensitive element does not touch the switch under most conditions, and the switch is pressed only when the internal air pressure of the sensitive element is higher than the external air pressure and the tire blowout signal needs to be output, which is in line with tire pressure.

Abstract

The invention designs a tyre burst detection method and a tyre burst sensor and provides a technical scheme aiming at solving the problems of leakage-free catastrophic failures, long-time pressing fatigues of a sensitive element and a switch and inner atmosphere pollution of a tyre. With the adoption of the technical scheme provided by the invention, the tyre burst sensor has a small size, and the increased weight is not more than 3 grams; the switch is not pressed by the sensitive element under most conditions and is pressed only if inner air pressure of the sensitive element is higher than external air pressure and a tyre burst signal needs to be output; and the tyre burst detection method meets actual requirements on detection of tyre burst.

Description

technical field [0001] The invention relates to a tire blowout monitoring technology for pneumatic tires for vehicles, in particular to a tire blowout detection method, a tire blowout sensor structure and a method for using the blowout sensor. Background technique [0002] Existing tire burst sensors all use a compressible elastic sealed cavity filled with a certain gas as a sensitive element; the sensitive element is compressed under air pressure conditions, and when the tire burst air pressure disappears, the sensitive element restores its shape and touches the switch to output a burst tire signal; this method can effectively detect any form of puncture, but any leakage caused by defects will lead to fatal failure of the puncture sensor. Metal materials with high density must be selected to meet the high sealing requirements of sensitive components. Secondly, the adjustment of action parameters Complicated, which is not conducive to large-scale mass production; the sensiti...
