Embodiment
Defer to technique scheme, as depicted in figs. 1 and 2, the utility model gives a kind of vehicle seat damping device, comprise the first vibration damper be arranged on automotive seat, described automotive seat comprises base plate 2 and is connected to the backrest plate 18 of base plate 2 side, base plate 2 offers groove, movable in groove cushion 1 is installed, it is inner that the first described vibration damper is positioned at base plate 2, first vibration damper comprises the first elastic axis 3 be supported on bottom cushion 1, the below of the first elastic axis 3 is provided with the first damper cylinder 15, first piston plate 4 is equipped with in first damper cylinder 15, first elastic axis 3 is connected with first piston plate 4, the first damping spring 5 is provided with between bottom first piston plate 4 and the first damper cylinder 15.
Automotive seat in this programme is substantially identical from structure with existing automotive seat, include the headrest 17 on base plate 2, backrest plate 18 and backrest plate 18, fluted on the base plate 2 that difference is the automotive seat of this programme, be equipped with cushion 1 in groove.Cushion 1 can move up and down in a groove, and driver or passenger are sitting on cushion 1.Conveniently install, also make passenger have better impression, cushion 1 comprises seat simultaneously, is provided with the cushion of middle part with depression above seat.
Cushion 1 is arranged to movable structure, is to install the first vibration damper.First vibration damper is made up of the first elastic axis 3, first damper cylinder 15, first piston plate 4 and the first damping spring 5, and the first vibration damper arranges multiple bottom cushion 1, and symmetrical.First piston plate 4 is assemblied in the first damper cylinder 15, can slide up and down in the first damper cylinder 15.The lower end of the first elastic axis 3 to extend in the first damper cylinder 15 and is supported on first piston plate 4.When vehicle generation shakes and is passed to seat, human body, due to inertia, can not be consistent with the motion of seat.The vibrations produced in vehicle traveling process are mainly the vibrations on above-below direction, in the process that vibrations occur, under the effect of acceleration, when cushion 1 moves down, first damping spring 5 is compressed, due to the effect of spring force, the movement velocity of human body on cushion 1 is slowed down, thus the impact that vibration-inhibition brings to people.
In order to make cushioning effect better, be distributed with below cushion 1 air bag 16, first damping spring 5 of multiple sealing uncompressed time, have gap between air bag 16 top and cushion 1; Namely at nominal conditions, air bag 16 with bottom cushion 1 does not contact.When shaking, and shake amplitude enough large time, now cushion 1 is excessive to the mobile range below groove, vibrations can not be offset well in first damping spring 5 short time, contact with air bag 16 when now cushion 1 moves to certain position, the oppressed distortion of air bag 16, plays auxiliary buffer function.Air bag 16 is airtight utricules, has good elasticity.After cushion 1 is separated with air bag 16, air bag 16 can restore to the original state automatically.
In order to reduce the vibrations of whole seat, in this programme, being provided with the second vibration damper further, making seat have double damping structure.
The second vibration damper is provided with below base plate 2, second vibration damper comprises the second elastic axis 14, the below of the second elastic axis 14 is provided with in the second damper cylinder 11, second damper cylinder 11 and is equipped with the second piston plate 12, between the second elastic axis 14 and the second piston plate 12, be provided with the second damping spring 13.
Different from the first vibration damper, in the second vibration damper, be connected with the second damping spring 13 below second elastic axis 14, second damping spring 13 is supported on second piston plate 12 that can slide in the second damper cylinder 11, by the compression process of the second damping spring 13, partial action can be offset in the vibrations of seat.
In order to make vibrations neutralization effect better, the second vibration damper arranges more than a pair below base plate 2, and in every a pair second vibration dampers, the bottom of the second damper cylinder 11 is all connected to same oil cylinder 6 by an oil pipe 10, is all filled with hydraulic oil in oil cylinder 6 and oil pipe 10.
Due to human body be sitting on cushion 1 time, the center of gravity deflection of human body is not fixing, and when therefore vibrations produce, the pressure of cushion 1 each several part is different, and pressure is different, then the movement velocity that cushion 1 each several part is downward is different.Second vibration damper is arranged in pairs, an oil cylinder 6 between every a pair second vibration dampers, when cushion 1 moves downward, first its part vibrations are offset by the second damping spring 13, the partial action of not offsetting is on the second piston plate 12, impel the second piston plate 12 to promote hydraulic oil motion, now section hydraulic oil is pulled to the bottom of another the second vibration damper; Owing to also having the second damping spring 13 in another second vibration damper, and the second elastic axis 14 pairs of piston plates have pressure, therefore the second damping spring 13 in another second vibration damper will be compressed, the vibrations namely can not offset in second vibration damper, will be offset by another the second vibration damper.Multipair second vibration damper is set, effectively can offsets vibrations.
More excellent a kind of set-up mode is, the drag reduction plug 9 that can slide in oil cylinder 6 is equipped with in oil cylinder 6, drag reduction plug 9 is provided with the first pod apertures 7 and the second pod apertures 8 penetrating drag reduction plug 9, in the first pod apertures 7 and the second pod apertures 8, all one-way valve is installed, two one-way valves open to difference, the hydraulic oil of drag reduction plug 9 both sides can only flow to opposite side from one of them pod apertures at one time.The object that arranges of drag reduction plug 9 is, when making hydraulic oil move under the driving at pressure, hydraulic oil is by pod apertures flow process, and form damping force in drag reduction plug 9 process of moving under the effect of the pressure, make vibration energy be converted into the heat energy of fluid, then be dispersed in surrounding environment by after the second absorber.
