A rubber spring (6) is sheathed on the outside of the guide post (9). The upper end of the rubber spring (6) is connected with the upper connecting bottom plate (5), and the lower end of the rubber spring (6) is connected with the lower connecting bottom plate (7).

Description

Rubber spring vibration-dampening chair
Technical field
The present invention is a kind of shock attenuation unit that is applicable to automotive seat, belongs to the technical field of automotive parts product design and manufacturing.
Background technology
Existing automobile seat is common seat at present, its seat spring support stiffness is constant, when the passenger of Different Weight takes, the natural frequency of seat-passenger system changes greatly, is difficult to avoid the uncomfortable frequency limit of human body, and the damping coefficient of common spring own is little, the absorption energy difference, effectiveness in vibration suppression is bad, vehicle riding comfort is poor when causing not having additional hydraulic damping shock absorber, takes for a long time and causes work fatigue easily, and industrial accident takes place.
Summary of the invention
Technical matters: the purpose of this invention is to provide the automobile rubber spring damping seat that a kind of automobile can extensively adopt, this seat makes full use of elasticity and the damping force characteristics buffering and the extraneous vibration that is delivered to seat of decay of rubber spring itself under the situation that does not need the composed of external damping device, rubber spring has the characteristic that becomes rigidity, can change along with the variation of different passenger's body weight, make the natural frequency of seat-passenger's system vibration change very little, and away from the least comfortable oscillation frequency of human body sensory, thereby the traveling comfort of raising shock absorbing seat.
Technical scheme: rubber spring vibration-dampening chair seat of the present invention, partly form by damping assembly, supporting component and guidance set etc.
Damping assembly comprises elements such as seat cushion, headrest, adjusting knob, rubber spring.Seat cushion by bolted connection to last connection base plate top, the headrest bolt together is to backrest, backrest is connected to by adjusting knob and connects on the base plate, the rubber spring upper head plate with bolt with on be connected base plate and link to each other, the shock damping action by elastomeric material has absorbed the vibration kinetic energy that passes over from the floor.
Structurally, automobile rubber spring damping seat is by headrest, backrest, adjusting knob, connecting base plate on the seat cushion forms, headrest links to each other with the top of backrest, the bottom of backrest is connected to by adjusting knob and connects on the base plate, seat cushion is positioned at and connects on the base plate, have a guidepost at last connection base plate, the upper end of this guidepost is fixed on back tightening nut and connects under the base plate, pilot sleeve is fixed on down and connects on the base plate, the hypomere of guidepost is positioned at pilot sleeve and can be free to slide, rubber spring is enclosed within outside the guidepost, the upper end of rubber spring with on be connected base plate and link to each other, the lower end is with to be connected base plate down continuous.Under connect base plate by being bolted on the vehicle frame floor, play the effect of fixing whole seat.Rubber spring is by polylith sheet steel and spaced the fusing of the hollow truncated cone-shaped rubber ring of polylith.
Guidance set comprises guidepost and pilot sleeve two parts, guidepost is connected to and connects on the base plate, pilot sleeve directly is fixed on down and connects on the base plate, both realize guidepost moving along pilot sleeve by free-running fit, guarantee that seat vibrates in vertical direction, make rubber spring give full play to its vertical cushioning performance.Relative position between guidepost and the pilot sleeve also plays spacing effect.
Beneficial effect: automobile rubber spring damping seat of the present invention utilizes rubber spring as main damping element, make full use of the nonlinear characteristic and the big damping force characteristics of elastomeric material of rubber spring stiffness variation, can both obtain the favorable damping effect when making the passenger of Different Weight take this seat, this apparatus structure novelty, assembling are made simple, when improving passenger comfort, reduce manufacturing cost, can be widely used in the especially abominable engineering truck of road conditions of automotive seat.
This seat makes full use of elasticity and the damping force characteristics buffering and the extraneous vibration that is delivered to seat of decay of rubber spring itself under the situation that does not need the composed of external damping device, rubber spring has the characteristic that becomes rigidity, can change along with the variation of different passenger's body weight, make the natural frequency of seat-passenger's system vibration change very little, and away from the least comfortable oscillation frequency of human body sensory, thereby the traveling comfort of raising shock absorbing seat.
Description of drawings
Fig. 1 is an automobile rubber spring damping seat overall structure scheme drawing of the present invention.
Fig. 2 is the sectional structure scheme drawing of automobile rubber spring damping seat vibration damping part of the present invention.
Parts among the above figure have: headrest 1, backrest 2, adjusting knob 3, seat cushion 4, on connect base plate 5, rubber spring 6, connect base plate 7, pilot sleeve 8, guidepost 9, back tightening nut 10 down.
The specific embodiment
Rubber spring vibration-dampening chair of the present invention is made up of damping assembly, supporting component and guidance set, and the damping assembly of this device comprises elements such as headrest 1, adjusting knob 3, seat cushion 4, rubber spring 6.To rest the head on and 1 link to each other with backrest 2 by bolt, backrest 2 is connected to by adjusting knob 3 and connects on the base plate 5, the angle that can use knob 3 to regulate backrests, seat cushion 4 by bolted connection to last connection base plate 5, seat cushion 4 should be selected the cushion with effectiveness in vibration suppression for use, must not use firm cushion, rubber spring 6 upper head plates with bolt with on be connected base plate 5 and link to each other, when running car produced vibration, the shock damping action by rubber spring the inside rubber bodies absorbed the effect that the vibration kinetic energy that passes over from the floor reaches vibration damping.
Supporting component mainly comprise connect base plate 5 with under be connected base plate 7, last connection base plate 5 directly links to each other with seat cushion 4, backrest 2, guidepost 9 usefulness back tightening nuts 10 back ofs the body are tightened to and connect on the base plate 5, the upper head plate of rubber spring 6 with on be connected base plate 7 and link to each other, the bottom plate of rubber spring 6 with under be connected base plate 7 and link to each other, rubber spring 6 is linked together whole seat system by polylith sheet steel and spaced the fusing of the hollow truncated cone-shaped rubber ring of polylith.Under connect base plate 7 and link to each other with pilot sleeve 8, following connection base plate 7 is by being bolted on vehicle body (or operator's compartment) floor.
Guidance set comprises guidepost 9 and pilot sleeve 8 two parts, guidepost 9 is connected to and connects on the base plate 5, pilot sleeve 8 directly is fixed on down and connects on the base plate 7, both realize guidepost 9 moving along pilot sleeve 8 by free-running fit, guarantee that seat vibrates in vertical direction, make rubber spring 6 give full play to its vertical cushioning performance, will apply lubricating oil in right amount in use between pilot sleeve 8 and the guidepost 9.
