Description

Technical Field

[0001] The present invention relates to the technical field of tire pressure gauges, and in particular to a tire pressure gauge specially designed for high-altitude cold regions with extreme temperature adaptability. Background Art

[0002] As we all know, the tire pressure should not be too high or too low during driving. Too high pressure can lead to tire blowout and traffic accidents, while too low pressure can accelerate tire wear and reduce driving speed and increase fuel consumption. Therefore, it can be seen that tire pressure detection is extremely important. Especially when inflating tires, tire pressure detection is of utmost importance.

[0003] Traditional tire pressure gauges have some shortcomings. In actual use, tire pressure gauges usually need to rely on built-in batteries for power supply to maintain normal operation. However, when such devices are used in high-altitude and cold areas, due to the extremely low outdoor ambient temperature, the chemical reaction rate inside the battery will be significantly reduced, resulting in a sharp decline in battery discharge performance, which is specifically manifested as insufficient battery output voltage, a significant reduction in effective capacity, and even instantaneous power outages under extreme low temperature conditions. This attenuation of battery power supply capacity caused by low temperature will directly cause the tire pressure gauge to have abnormal data, display failure, or be completely unable to start when measuring outdoors, seriously affecting work efficiency and increasing operational difficulty, bringing obvious usage obstacles to vehicle safety monitoring work. Therefore, there is an urgent need for a solution that can alleviate the above problems. Summary of the Invention
