Pipe is slidably connected in body and with inner tube, and the body is provided with one-level relief hole, offers in said inner tube and is let out with one-level
Press the two level relief hole of hole coaxial line.Relief tube is placed vertically, when the gas concentration or gas pressure in shock-absorption air bag
When excessive, inner tube is jacked up along body by gas and moved up so that one-level relief hole and two level relief hole coaxial line, gas
Body will discharge from two relief holes, when gas concentration decline or insufficient pressure, effect of the inner tube in gravity in shock-absorption air bag
Under move down, relief hole one and two not coaxial line of relief hole, stop exhaust.
Further, the inwall of the body is provided with chute vertically, and said inner tube is provided with the cunning being connected with slide
Bar.The setting of draw runner and chute ensure inner tube in body will not left and right displacement, ensure that one-level relief hole and two level are let out with this
Pressure hole can guarantee that coaxial line.
Further, the outer surface of the shock-absorption air bag is provided with corrugated projection.It is corrugated it is raised reduce air bag with
The contact area of battery case can ensure buffering effect again simultaneously.
Further, the battery case also includes nitrogen gas generating device, and the outlet of the nitrogen gas generating device is provided with flow
Regulating valve, the flow control valve connect airway tube.When water electrolytic gas is not enough to the expansion of support air bag, by there is nitrogen hair
Raw device connection, to supplement nitrogen.
Further, sensor, the sensor electrical connection nitrogen gas generating device and flow are also included in the battery case
Regulating valve.When acute collision occurs, sensor detects collision dynamics, controls nitrogen gas generator and flow control valve to subtracting
Nitrogen is filled into shake air bag, and supplement prevents from colliding the damage to battery rapidly.
