When self-propelled vehicle generation head-on crash, promptly this moment, first crash bar 1 was positioned at the front portion of self-propelled vehicle, impact is with first crash bar 1, first piston push rod 2 moves backward with the first piston 3 that has first piston injection hole 4, under the extruding of first piston 3, impact passes to the bottom of second piston 11 immediately, second piston 11 directly passes to impact on the second piston cylinder end cap 14 again, because the second piston cylinder end cap 14, second piston cylinder 15, connecting pipe 8, high-pressure buffer chamber 1601 on the energy consumer pedestal 1600 is connected successively, so connecting pipe 8, second piston cylinder 15, energy consumer pedestal 1600 will be subjected to tensile force backward, it is connecting pipe 8, second piston cylinder 15, the energy consumer pedestal is in extended state, thereby can guarantee effectively that occupant space forwardly is not extruded distortion in the collision process.
Because the pressure of anti-freezer rises rapidly, highly pressurised liquid will be by two approach injection consumed energies: first approach is that highly pressurised liquid will be by the piston injection hole 4 on the first piston 3 high speed jet and consumed energy forward; The anti-freezer that ejects from piston injection hole 4 enters in the annular space that end face, first piston cylinder end cap 6, first piston cylinder 7, the first piston push rod 2 of first piston 3 form; Because the liquid of high speed jet injects directly on the first piston cylinder end cap 6, thereby first piston cylinder 7 will be subjected to tensile force forward, promptly first piston cylinder 7 also is in extended state; First piston cylinder 7, novel switched formula are sprayed energy consumer 16, connecting pipe 8 and second piston cylinder 15 and all are in extended state in sum, this means that not only occupant space forwardly is not extruded distortion in the collision process, and can guarantee that driving engine squeeze and destroy can not take place.Second approach is that highly pressurised liquid will spray the energy consumer high speed jet and consumed energy by novel switched formula.
2) how the novel switched formula injection of surface analysis energy consumer works down.
Before first piston 3 arrives the first screw joint 17, all top shuttle valve 1609,1618,1627, the pressure that 1636 end face is subjected to and all bottoms shuttle valve 1605,1614,1623,1632 pressure that are subjected to are suitable, but because of all top shuttle valve 1609,1618,1627,1636 diameter is respectively greater than all bottoms shuttle valve 1605,1614,1623,1632 diameter, so top shuttle valve 1609,1618,1627,1636 will be seated in all top valve barrel 1610,1619,1628,1637 bottom, the i.e. first shuttle valve assembly, the second shuttle valve assembly, the 3rd shuttle valve assembly, the 4th shuttle valve assembly is in extreme lower position, and this moment, highly pressurised liquid will be through bottom valve barrel (1606,1615,1624,1633) with bottom shuttle valve (1605,1614,1623,1632) fluid passage between, middle part valve barrel (1608,1617,1626,1635) with middle part shuttle valve (1607,1616,1625,1634) fluid passage between, pedestal injection hole (1604,1613,1622,1631) high speed jet is to low pressure buffer chamber 1602 and consumed energy.The liquid that enters low pressure buffer chamber 1602 enters anti-freezer box 26 by low pressure communicating pipe 25.
As shown in figure 10, when first piston 3 has just passed through the first screw joint 17, because the pressure of the annular space that the end face of first piston cylinder 7, first piston push rod 2, first piston 3, first piston cylinder end cap 6 constitute is for very low, the pressure of the first top shuttle valve, 1609 end faces will reduce rapidly, the first shuttle valve assembly will rise rapidly, promptly the first bottom shuttle valve will be pressed on the first bottom valve barrel tightly, fluid passage between the first bottom valve barrel 1606 and the first bottom shuttle valve 1605 is closed at this moment, and the first pedestal injection hole 1604 will stop to spray.The minimizing of spraying hole count will help colliding the hardness of later stage raising self-propelled vehicle.
The rest may be inferred, and along with the further propelling of first piston, the second pedestal injection hole 1613, the 3rd pedestal injection hole 1622, the 4th pedestal injection hole 1631 will stop to spray gradually.
