Similarly, if the height of the air bag needs to be reduced, the central valve switch is only needed to be switched off, the left air bag lifting switch and the right air bag lifting switch are still closed, and the air in the left air bag and the air in the right air bag can be exhausted to the air through the central electromagnetic valve, so that the height of the air bag is reduced, the air exhaust can be stopped at any time in the process, and the height of the air bag can be adjusted at will.

In addition, it should be noted that if the left and right airbags need to be controlled independently, the operation can be realized only by closing the height-adjusting side airbag lifting switch and not by opening the height-adjusting side airbag lifting switch, for example, if the left airbag needs to be controlled independently, only by closing the left airbag lifting switch and not by closing the right airbag lifting switch; for another example, if the right airbag needs to be controlled independently, only the closing of the right airbag lifting switch needs to be adjusted, and the closing of the left airbag lifting switch does not need to be adjusted.
