For solveing the technical problem, the technical solution of the utility model: a kind of automotive airbag vibration damper, comprise fuel tank, the inner of piston rod extend in fuel tank, and outer end reaches the outside of fuel tank, between the outer side and fuel tank of piston rod, be provided with air bag, it is characterized in that, the dust-proof cover of metal is socketed in the periphery of piston rod, and an end of dust-proof cover and the outer end of piston rod are connected, and the other end of dust-proof cover extend into fuel tank position; The two end part of air bag are fixed by socket respectively on the outer circumferential face of dust-proof cover and fuel tank; Dust-proof cover is provided with valve, and valve links up outside and the inside of dust-proof cover.During the work of this vibration damper, piston rod does the motion relative to fuel tank vertically, and when piston rod action, air bag produces certain deformation and adapts with the axial motion of piston rod.Dust-proof cover extend into fuel tank position, refer to dust-proof cover no matter be in all to overlap with store oil under which kind of state between have overlapping, dust-proof cover is positioned at the radial outside of fuel tank.
As preferably, the air bag end being connected fixing with fuel tank is folded into bilayer, and this bilayer fits together.This end of air bag is in double layer construction, and be convenient to air bag when doing the deformation adapted, air bag conveniently produces deformation in this end, and the damage of this deformation to air bag is little.
As preferably, the internal layer outer circumferential face of the air bag end being connected fixing with fuel tank binds round and is connected to the first pressure ring, the outer circumferential face of fuel tank is provided with in the first pressure ring position some along fuel tank dentation convex body circumferentially.Realize the periphery of air bag lock ring at fuel tank by the first pressure ring, structure is simple, and the axial stability between air bag and fuel tank is good.
As preferably, the air bag end being connected fixing with dust-proof cover is bound round and is connected to the second pressure ring, the outer circumferential face of dust-proof cover is provided with some along dust-proof cover dentation convex body circumferentially in the second pressure ring position.The axial soundness connected between dust-proof cover with air bag is good, is convenient to realize being connected and fixed between dust-proof cover and air bag.
As preferably, the truncation surface of described second pressure ring is V-shaped.Second pressure ring is described shape, and the second pressure ring inwardly has undergauge deformation at axial medium position place, and this is convenient to the second pressure ring and is pressed on the outer circumferential face of dust-proof cover.
As preferably, be fixed by socket hood-like connection cover in the outer end of piston rod, connect the opening of cover towards dust-proof cover, connect cover grafting and be fixed in dust-proof cover.Connect cover, being connected and fixed between convenient dust-proofing cover and piston rod outer end by arranging, and dust-proof effect also can ensure.When realizing connecting, dust-proof cover is generally realized by the mode of welding between covering with connection.
Therefore, the beneficial effects of the utility model: owing to being provided with dust-proof cover, this dust-proof cover can extend into fuel tank position, dust-proof cover follow piston rod together action time, dust-proof cover and fuel tank realize being socketed and can providing good radial support for air bag, air bag is lateral deviation not easily, both improve the radial stability of piston rod, to reduce the friction between piston rod and fuel tank, the radial stability of air bag itself can be ensured again, air bag is when doing adaptability deformation, the deformation of air bag is dispersed, not easily produce fatigue damage at certain some place of air bag, and fully can ensure the working life of air bag.
Accompanying drawing explanation
Fig. 1 is the longitudinal sectional view of the utility model automotive airbag vibration damper.
