Description

Technical Field

[0001] The invention relates to an automobile rescue auxiliary product, in particular to an automobile tire blowout self-rescue auxiliary device with an overspeed alarm function. Background Art

[0002] During the driving process, a tire blowout may occur due to reasons related to the road surface or the vehicle itself. After a tire blowout, the tire loses air pressure instantly and the sidewall shrinks inward. If the vehicle continues to drive, it will cause the vehicle to lose balance. In serious cases, the vehicle will turn to the side of the blowout, which is very likely to cause a traffic accident. After a car tire blowout, the spare tire is often replaced to drive the car to a repair point to repair or replace the blowout tire. Due to the large weight of the tire, the method of replacing the spare tire is not only very laborious, but also has a certain complexity in the tire replacement operation. At the same time, improper installation of a car tire blowout will bring certain safety hazards. Especially for drivers with less strength, it is particularly inconvenient to replace a vehicle tire blowout, and a more convenient self-rescue auxiliary device after a car tire blowout is urgently needed.

In this way, as the wheel vibrates, the contact surface S changes, thereby changing the pressure. The pressure data detected by the pressure sensing module 621 within the T3 time are F1.F2.F3………Fn respectively, and the pressure sensing module 621 transmits F1.F2.F3………Fn to the third central control module 622.
