New method of automotive tire pressure detection and safe identification

Abstract

The invention provides a method for correspondingly marking the most protuberant part of the deformed rubber corresponding to the outer side of an automobile tire with a white fluorescent paint line and coating a red fluorescent paint line in the position which is one second distance below from the white line as a safety mark according to the allowable normal inflation pressure standard range calibrated when the tires of sedans and miniature vehicles leave the factory (for example, the allowable normal inflation pressure standard ranges of a 1.5t FIAT sedan, a 0.6t CHANG'AN STAR miniature minibus and a 1.0t LINGYANG sedan are respectively 2.3 to 2.8 Kg / cm<2>, 2.2 to 2.5Kg / cm<2> and 2.2 to 2.6Kg / cm<2>). When the red fluorescent paint line disappears and the most protuberant part of the deformed rubber on the outer side of the tire is above the white fluorescent paint line, the tire pressure is indicated to be too low, and measures, such as inflation, tire repair, etc., should be carried out. When the most protuberant part is below the white fluorescent paint line and above the red fluorescent paint line, the tire pressure is indicated to be too high, and the measure of deflation should be carried out. The method has the advantages of visibility, rapidness, convenience, safety, practicality and low cost, and is easily accepted by drivers and tire manufacturers, completed at one time in the tire manufacturer and easily generalized and applied.

Description

technical field [0001] The invention relates to the field of automobile and safety engineering, in particular to a method for automobile tire pressure detection and safety identification. Background technique [0002] With the development of my country's economy and society and the improvement of people's living standards, more and more families have the ability to buy cars, especially cars. While cars bring convenience to people's life and travel, the safety performance of cars has also become the focus of consumers' attention. According to statistics from safety traffic management departments across the country in 2007, 46% of traffic accidents on expressways were caused by tire failures, among which tire blowouts accounted for 70% of the total accidents. Abnormal tire pressure is the cause of traffic accidents. One of the main causes of accidents. The risk of tire blowout accidents is high, and the probability of car crash is high, which has caused huge losses to famili...

AI Technical Summary

Problems solved by technology

[0006] 1) The direct detection has large errors and poor stability, and requires multiple high-frequency calibrations to overcome this problem, and each electronic detector is expensive, and is only limited to high-end cars;

[0007] 2) Indirect detection requires quite complicated and high-performance computer calculations, and the detection error is large. At the same time, each monitor is expensive, and it is only limited to high-end cars;

[0008] 3) The electronic pressure sensor is easily affected by changes in the driving environment and has poor stability;

[0009] 4) High cost, short service life, inconvenient installation, difficult to be accepted by consumers, difficulty in application and promotion, etc.
