The present invention relates to a tire pressure air gun structure for fast and accurate measurement, and in particular to a tire pressure that can be easily and simply measured, and can quickly allow users to inflate with one hand easily, and at the same time, can reach When the target air pressure value, can adjust the air pressure flow in time, and the innovative structure designer who can directly view the air pressure value from the angle of the man-machine interface.

According to the fact, vehicles have become an important means of transportation in modern society, so driving safety has become an urgent issue. The safety issues that most people care about when driving are mostly the number of airbags, the availability of various active and passive safety equipment, or the vehicle. The strength of the body structure is used as an indicator of safety, but the appropriateness of the tire pressure during driving is an important part of driving safety. If the tire pressure is too low during driving, the rolling resistance of the tire will increase, and Affects the handling of the driving, and when cornering at high speed, the tire may also get out of the rim and cause a serious accident. At the same time, too low tire pressure will increase the deformation of the tire and increase fuel consumption. When the tire pressure is too high during driving, the contact area between the tire and the ground will be reduced, which will weaken the grip between the tire and the ground. It may cause slippage during driving, and the high temperature during driving may cause the tire with too high tire pressure to burst. According to the data of the Ministry of Transport, whether the tire pressure is normal or not is often related to the safety of pedestrians, especially when more than 70% of national road accidents are explosive. It is very important to pay attention to the wearability of the tire; when the tire is inflated and deflated, the air pressure flow rate is fixed, so the user cannot adjust the air pressure flow while inflated, so that it is easy to inflate or deflate between the target gas value. If the value exceeds a certain value, the process of filling and deflating back and forth to achieve the precise target air pressure value is tedious and time-consuming. Furthermore, traditional tire pressure gauges often need to be viewed in a poor posture due to design position problems.
