Tire pressure monitoring and alarming device

Abstract

The invention discloses a tire pressure monitoring and alarming device, an air inlet is arranged on the side surface of a reference chamber, a liftable reference chamber cover is arranged on the bottom, when a bottom nut is screwed on a valve core, a project part of a valve port of the reference chamber cover can open the valve core at the beginning, gas in the tire enters into the reference chamber through the valve port and an air inlet; the bottom nut is continuously screwed, when the nut is screwed to the set position, the end part of the valve core presses upward on the reference chamber cover, the reference chamber cover carries a sealing ring to move upward, the sealing ring compacts on the reference chamber, the air inlet is sealed and blocked, thereby the reference chamber forms a seal chamber. When the pressure of the tire is excessively low, the diaphragm of the reference chamber ejects downward, and is conducted with a contact disc, the contact disc is conducted with an anode access point of an alarm circuit board through a spring, the reference chamber cover, the bottom nut and a case, thereby the alarm circuit board is electrically alarmed. The alarm device has the advantages of simple structure, reliable operation and low cost.

Description

technical field [0001] The invention relates to a device for real-time monitoring of automobile tire pressure and alarming. Background technique [0002] Car tires usually have a standard pressure. When the tire pressure is low, the handling performance of the car will be affected, the wear of the tire will be increased, and the energy consumption of the car will be increased. Especially when the tire pressure of each tire of the car is unbalanced, it will have a bad influence on the drivability and safety of the car. [0003] In order to avoid the above situation, a tire pressure alarm device came into being, and the existing tire pressure alarm device is mainly in the form of an electronic sensor, which senses the air pressure in the tire through an electronic chip, and the electronic chip needs to be powered 24 hours a day state, its power consumption is large, the battery is easy to run out, and needs to be replaced frequently, which brings inconvenience to the user. ...

AI Technical Summary

Problems solved by technology

[0002] Car tires usually have a standard pressure. When the tire pressure is low, the handling performance of the car will be affected, the wear of the tire will be increased, and the energy consumption of the car will be increased.

Especially when the tire pressure of each tire of the car is unbalanced, it will have a negative impact on the driving performance and safety of the car

[0003] In order to avoid the above situation, a tire pressure alarm device came into being, and the existing tire pressure alarm device is mainly in the form of an electronic sensor, which senses the air pressure in the tire through an electronic chip, and the electronic chip needs to be powered 24 hours a day state, its power consumption is large, the battery is easy to run out, and needs to be replaced frequently, which brings inconvenience to users

Especially once the battery is exhausted and the user fails to replace it in time, the alarm device will not be able to alarm normally, posing a safety hazard

In addition, electronic chips have requirements for the working environment. In harsh environments, they are prone to failure and cannot work normally.

In addition, the cost of electronic chips for sensing air pressure is also relatively high
