Tire burst monitoring sensor

Abstract

The invention discloses a tire burst monitoring sensor, wherein tiny exhaust damping holes are arranged on an elastic conducting plate; when a tire has normal and slow air permeation, although the air pressure of a monitoring cavity arranged above the elastic conducting plate is reduced, the air in a reference cavity can be discharged into the monitoring cavity through the exhaust damping holes on the elastic conducting plate, so that the air pressure in the reference cavity is guaranteed to be consistent with that in the monitoring cavity in time, a negative pole of a battery is not conducted by the upward bulge of the elastic conducting plate, and the long-time slow air permeation of the tire is avoided being identified as tire burst rapid air permeation by the tire burst monitoring sensor; during the tire burst rapid air permeation, the air pressure in the reference cavity can not be discharged outside in time, the air pressure difference between the reference cavity and the monitoring cavity rapidly rises, the elastic conducting plate is driven to protrude upwards, the negative pole of the battery is connected, a radio alarm signal and a flashing light alarm are transmitted by a transmission module, and a tire burst prevention device is started after a mainframe in an automobile receives the radio alarm signal, so that the automobile is guaranteed not to turn on the side.

Description

technical field [0001] The invention relates to a sensor which can monitor in real time whether rapid air leakage occurs in automobile tires. Background technique [0002] It is unpredictable for the car to be scratched or punctured when the car is running on a complex road. Therefore, in order to prevent the car from rolling over due to a flat tire, the prior art installs a flat tire device on the car. When started in time, the car with a flat tire can keep the balance of the body, thereby ensuring driving safety. Whether the run-flat device can be started in time requires the assistance of a sensor that can monitor whether the car tires have rapid air leakage in real time, so as to transmit the monitored rapid air leakage signal and trigger explosion-proof when the car has a rapid tire leak. The tire unit starts. [0003] In the prior art, there are a variety of sensors that can monitor whether there is air leakage in automobile tires in real time. For example, the tire...

[0005] However, in the existing tire pressure monitoring and alarming devices of this type, when working, its reference cavity is completely isolated from the space on its outside, and the internal pressure remains constant. However, during the use of the car, the high-pressure gas of the tire must be released slowly. The ground leaks out, causing the monitoring cavity connected to the tire to slowly generate a pressure difference with the completely isolated reference cavity. When the pressure difference reaches a certain level, the elastic conductive sheet will bulge upward and deform, and the battery will The negative electrode of the tire is turned on, so that the alarm circuit board is energized to alarm and send out a signal. Therefore, when this type of tire pressure monitoring and alarm device is used to assist the process of the anti-flat tire device, it is impossible to distinguish between the slow air leakage of the tire and the rapid tire blowout. Air leakage, the normal slow air seepage is often misjudged as a car blowout and rapid air leakage, and triggers the explosion-proof device to start, causing the blow-out device to start even when the tire is not blown out, causing inconvenience to the driver
