Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to an air bag pressure monitoring sensor. Background Art

[0002] The airbag pressure monitoring sensor is a sensor used to monitor the internal pressure of the airbag tray used in the production and manufacturing process of automotive power batteries. Its function is to monitor the internal pressure of the airbag tray in real time during the entire battery production and manufacturing process, and give air pressure alarm information when the pressure is too low or too high, inform the relevant workstations of abnormalities, ensure the consistency of the battery in the production and manufacturing process, improve the battery capacity, and ensure the battery life. Its working principle is as follows:

[0003] (1) Pressure detection: When the sensor is in operating mode, it will detect the pressure value and change value of the airbag in real time, and execute an alarm according to the set alarm threshold.

[0004] (2) Signal output: Once the sensor detects that the pressure value and change value exceed the threshold value, it will send data to the signal receiving device wirelessly. The receiving device will notify the actuator to inflate or deflate the airbag according to the alarm content.

[0005] (3) Consistent performance: By timely and accurately monitoring the airbag pressure value and change value, this sensor helps to ensure the stability of the airbag tray pressure and ensure that the battery production manufacturing process parameters are constant.
