After cylinder is compressed in traditional damping stored energy mechanism, the spatial volume rate of change of piston both sides is because living in cylinder
The presence of stopper rod is that different, traditional solution method is increase compensation space, and the use of this method can cause mechanism to answer
Miscellaneous degree lifting.In order that being solved the above problems with simple mechanism, the piston that the present invention designs can be according to the mobile tune of piston rod
The thickness of piston in itself is saved to adapt to the spatial variations of piston both sides.
Cylinder in the present invention is fixed by chassis support plate, and air motor is fixed by motor fixed plate；Generator passes through generating

Interior bottom；To sum up piston mechanism moves up and down repeatedly successively, until the energy absorption of impulsive force is finished.
The design for the length that the Cavity surface length for putting tooth cavity is less than cylinder inner casing face is to ensure that lower spring is compressed to pole
Lower piston plate prevents mechanical damage without impinging on cylinder lower inner casing face in limited time.The design of upper spring and lower spring is for piston machine
Under the limiting case moved up and down, piston mechanism does not touch structure with cylinder lower inner casing face or cylinder cover plate rigid phase, while can also
Play a part of cushion impact forces.The design of thread gap and breach sliding block is to ensure that piston bottom plate and piston head plate will not
Rotated with fluted disc, while the high-pressure helium between sealing piston bottom plate and lower piston plate can also be played a part of.
When damper moment is by smaller impulsive force, piston mechanism can produce smaller moving displacement；Now
Put gear mechanism and triggering gear can be by smaller interaction force, then the flexible centrifugation being subject to of getting stuck in pendulum gear mechanism
Power can not be such that flexible get stuck snaps into the space between two limiting plates, so as to which flexible get stuck will not be by limiting plate with regard to very little
Position-limiting action, triggering gear will be unable to swing tooth produce meshing relation, so as to can not drive retractable cone tooth, Transmission gear and
The rotation of fluted disc, the space for ultimately resulting in piston bottom plate and piston head plate do not produce change, promote damping spring, upper spring and under
Spring withstands shocks power.When damper moment is by big impulsive force, piston mechanism can produce big moving displacement；Now put
Gear mechanism and triggering gear can be by big interaction forces, then the flexible centrifugal force being subject to that gets stuck in pendulum gear mechanism just compares
It is larger, it is sufficient to flexible get stuck is snapped into the space between two limiting plates, get stuck so as to flexible, oscillating rod and swing tooth and fix
Firmly, in this case, swinging the fixation of tooth will make swing tooth produce normal meshing relation with triggering gear, and then drives and stretch
The rotation of contracting cone tooth, Transmission gear and fluted disc, so that space the moving up and down with fluted disc of piston bottom plate and lower piston plate
And change.The change space of piston bottom plate and lower piston plate compensate for because when cylinder is compressed piston rod enter cylinder in increase
Space, and then piston mechanism can adapt to piston both sides according to the thickness of the mobile regulating piston mechanism of piston rod in itself
Spatial variations.In damper by the whole work process of large impact, by putting gear mechanism with triggering the engaging come band of gear
Active toothed disk moves up and down, so that the space of piston bottom plate and lower piston plate changes with moving up and down for fluted disc, reduces
The large impact power that damping spring, upper spring and lower spring are born, it is therefore prevented that large impact power produces to damper internal structure
Mechanical damage.
Can be by the energy of impact through air motor and generating relative to traditional cushion technique, during normal work of the present invention
Machine conversion energy storage is got up, and realizes the purpose of quick apparatus with shock absorbing and rapid decay vibrations；Also solved in the present invention simultaneously
The problem of damper produces mechanical damage when by large impact power to damper internal structure, serve protection damper
Effect, extend the service life of damper.Its is simple and compact for structure, and energy saving is high, has preferable practical effect.

（b）Shown, when damper moment is by smaller impulsive force, piston mechanism can produce smaller moving displacement；Now
Put gear mechanism 45 and triggering gear 17 can by smaller interaction force, then flexible in pendulum gear mechanism 45 get stuck 51 by
The centrifugal force arrived can not be such that flexible get stuck 51 snaps into the space between two limiting plates 48 with regard to very little, get stuck 51 so as to flexible
It will not be triggered gear 17 by the position-limiting action of limiting plate 48 and will be unable to produce meshing relation with swinging tooth 54, so that can not band
The rotation of dynamic retractable cone tooth 28, Transmission gear 37 and fluted disc 26, ultimately result in the space of piston bottom plate 27 and piston head plate 20 not
Change is produced, promotes damping spring 2, upper spring 18 and lower spring 22 to withstand shocks power.In Figure 21（c）It is shown, work as damper
When moment is by big impulsive force, piston mechanism can produce big moving displacement；Now put gear mechanism 45 and the triggering meeting of gear 17
By big interaction force, then flexible 51 centrifugal force being subject to that get stuck in pendulum gear mechanism 45 are with regard to bigger, it is sufficient to make to stretch
Contracting, which is got stuck, 51 to be snapped into the space between two limiting plates 48, so as to which flexible get stuck and swings tooth 54 and fixed 51, oscillating rod 52,
In this case, swinging the fixation of tooth 54 will make swing tooth 54 produce normal meshing relation, and then band with triggering gear 17
The rotation of dynamic retractable cone tooth 28, Transmission gear 37 and fluted disc 26 so that the space of piston bottom plate 27 and lower piston plate 21 with
Fluted disc 26 is moved up and down and changed.The change space of piston bottom plate 27 and lower piston plate 21 compensate for because cylinder 6 compressed when
Piston rod 3 enters the increased space of institute in cylinder 6, and then piston mechanism can be according to the mobile regulating piston mechanism of piston rod 3
The thickness of itself is to adapt to the spatial variations of piston both sides.In damper by the whole work process of large impact, passing through pendulum
Gear mechanism 45 is engaged come moving up and down with active toothed disk 26 with triggering gear 17, so that piston bottom plate 27 and lower piston plate 21
Space moving up and down and change with fluted disc 26, reduce damping spring 2, upper spring 18 and lower spring 22 born it is big
Impulsive force, it is therefore prevented that large impact power produces mechanical damage to damper internal structure.
Can be by the energy of impact through air motor 12 and hair relative to traditional cushion technique, during normal work of the present invention
Motor 9 is changed energy storage and got up, and realizes the purpose of quick apparatus with shock absorbing and rapid decay vibrations；Also solved in the present invention simultaneously
The problem of damper of having determined produces mechanical damage when by large impact power to damper internal structure, serves protection damper
Effect, extend the service life of damper.Its is simple and compact for structure, and energy saving is high, has preferable practical effect.
