Description

Background art:
the tire pressure detector is a device for detecting the tire pressure of an automobile tire, and no matter how excellent the performance of an engine or a chassis of the automobile is, the tire pressure detector can be expressed only by the contact of the tire and a bottom surface, and the improper tire pressure often causes the incomplete performance of the automobile. When the tire pressure is too high, the contact area between the tire and the ground can be reduced, the pressure born by the tire is relatively increased, and the grip of the tire can be influenced. In addition, when a vehicle passes through a sill or a bumpy road surface, the shock is absorbed in the tire because of insufficient space, so that the driving stability and the riding comfort are affected, the impact force on a suspension system is increased, and the damage is caused. Therefore, the proper air pressure in the tire is not only beneficial to the driving comfort of people, but also greatly guarantees safe driving.

The tire pressure of a common small axle vehicle is between 2.3pa and 3pa, and the tire pressure of a small truck, a bus or a large truck is higher, so the highest values which can be borne by the tire pressure detectors of different types of vehicles are different, but if the tire pressure detectors can not bear the pressure, if the tire pressure detectors can not accept the pressure, then the external tire pressure detectors are installed on the tires, the air pressure of the tires can not be accurately monitored, the condition of air leakage can be caused, and the driving is damaged.
