Air pressure testing system

Abstract

The invention discloses an air pressure testing system. The system comprises a seal test container, a first air pressure gauge, a tire pressure sensor, a cylinder, a controller and a solenoid valve; the first air pressure gauge is arranged on the seal test container, the cylinder is communicated with the seal test container through a fluid, the solenoid valve is arranged at an air outlet of the cylinder, the solenoid valve is electrically connected with the controller, and the controller controls the solenoid valve to be opened or closed according to operation signals; the tire pressure sensoris arranged in the seal test container and detects air pressure information in the seal test container. Accordingly, the problems that in the prior art, when pressure bearing testing is conducted onthe tire sensor, it is time-consuming for disassembling and assembling the sensor, or due to the fact that an artificial compressed air pipe is unstable, air pressure regulation is not flexible, and batched testing and production are not facilitated and are very inconvenient can be solved.

Description

Technical field [0001] The invention relates to the technical field of tire pressure testing, in particular to an air pressure testing system. Background technique [0002] At present, there are many automobile manufacturers, with different countries and different types. Tire pressure and temperature are very important to the safe driving of a car. Unreasonable tire pressure (especially low pressure) will significantly increase fuel consumption. To monitor the tire pressure of motor vehicles, tire pressure sensors are generally used to measure tire pressure. However, when the tire pressure sensor is produced, the tire pressure sensor needs to be tested under pressure. Usually, an external tire pressure sensor or a built-in tire pressure sensor is used for testing. Among them, the test method of the external tire pressure sensor is : The sensor is installed on the air pipe with the car valve for testing, and the test method with the built-in tire pressure sensor is adopted: the a...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the deficiencies of the prior art, the object of the present invention is to provide an air pressure test system, which can solve the problem of time-consuming disassembly and assembly of the sensor or instability of the manual air pressure tube in the prior art when the tire pressure sensor is subjected to a pressure test. It leads to inflexible air pressure adjustment, which is not conducive to batch testing and production, and is very inconvenient.
