Detailed description of the invention
Defer to technique scheme, referring to Fig. 1-2, automobile absorber based on piezoelectric stack energy regenerating of the present utility model, oil storage cylinder barrel 1 oil storage cylinder barrel 1 is provided with work cylinder barrel 2, it is provided with energy recycle device 3 between described oil storage cylinder barrel 1 and work cylinder barrel 2, energy recycle device 3 includes piezoelectric stack 3-1, in described automobile absorber work process, fluid moves back and forth between work cylinder barrel 2 and oil storage cylinder barrel 1, namely fluid is flowed into oil storage cylinder barrel 1 by the cylinder barrel 2 that works or is flowed into work cylinder barrel 2 by oil storage cylinder barrel 1, drives piezoelectric stack 3-1 to shrink or elongation.
Wherein, in work cylinder barrel 2 and oil storage cylinder barrel 1, all it is filled with fluid, is provided with piston 2-1, piston 2-1 in work cylinder barrel 2 and connects piston rod 2-2, piston 2-1 both sides and be separately installed with flowing valve 2-3 and rebound valve 2-4; The bottom surface of work cylinder barrel 2 is provided with recuperation valve 2-5 and compression valve 2-6.
Amortisseur of the present utility model is by the contraction of the dynamic piezoelectric stack of the Sports band of piston or elongation, it is achieved mechanical energy converts electric energy to, reclaims automobile energy in vibration processes, it is to avoid the waste of energy; Apparatus structure is simple, with low cost and easy for installation.
Amortisseur of the present utility model is arranged on automobile, if the chamber between piston 2-1 and work cylinder barrel 2 bottom surface is cavity of resorption, the chamber between piston 2-1 and work cylinder barrel 2 end face is epicoele; When automotive wheel rolls on projection or rolls out pit, wheel shifts near vehicle frame, and amortisseur is compressed, and the piston 2-1 in work cylinder barrel 2 moves to work cylinder barrel 2 bottom surface, and cavity of resorption volume reduces, and its internal oil pressure raises, and fluid flows upper intracavity through flowing valve 2-3; Owing to epicoele is accounted for a part of space by piston rod 2-2, the volume that the volume that upper intracavity increases reduces less than cavity of resorption, therefore a part of fluid pushes compression valve 2-6 open, stream is in oil storage cylinder barrel 1, stream acts on described piezoelectric stack 3-1 to this part fluid of oil storage cylinder barrel 1, piezoelectric stack 3-1 is shunk, and then produces electric charge output, it is achieved mechanical energy converts electric energy to;
When automotive wheel rolls down projection or rolls into pit, wheel is away from vehicle frame, amortisseur is stretched, now, piston 2-1 in work cylinder barrel 2 moves to the top of work cylinder barrel 2, piston 2-1 epicoele oil pressure raises, flowing valve 2-3 closes, the fluid of upper intracavity is pushed rebound valve 2-4 open and is flowed into lower intracavity, also due to the existence of piston rod 2-2, the fluid flowed out from epicoele is not enough to be full of the volume that cavity of resorption increases, lower intracavity produces certain vacuum, fluid in oil storage cylinder barrel 1 is pushed intracavity under recuperation valve 2-5 flows into open and is supplemented, so, piezoelectric stack 3-1 returns to origin-location, whole motor process terminates.
