Detailed description of the invention
Defer to technique scheme, as shown in Figures 1 to 4, this programme gives a kind of car seat damping device, comprise the reaction plate 7 that is connected with automotive interior base plate and with the supporting disk 9 be connected bottom the seat 13 of automotive seat, piston device 8 is provided with between reaction plate 7 and supporting disk 9, the lower end of piston device 8 is movable to be assemblied in a damping chamber 5, and the bottom of piston device 8 is provided with relief spring 8-5; Described supporting disk 9 is connected with piston device 8 is movable, and reaction plate 7 is cemented in bottom damping chamber 5.
The bumper of this programme is arranged on the bottom of automotive seat, to replace the original component with ground car internal backplane connecting bridge of automotive seat.Bumper arranges multiple bottom automobile seat 13, is uniformly distributed, and each bumper is a vibration absorption unit, separate between bumper.
For the ease of assembling, in this programme, be provided with reaction plate 7 and supporting disk 9.Wherein, reaction plate 7 offers lower assembly opening 6, be fixed on car floor by bolt; Supporting disk 9 offers assembly opening 2, by bolts assemblies bottom automobile seat 13, thus complete installation process easily.
Be piston device 8 for the keystone configuration of damping in this programme, piston device 8 is assemblied in a damping chamber 5, is connected between piston device 8 with damping chamber 5 for movable; Leave a part of space between bottom piston device 8 and bottom damping chamber 5, and in the bottom of piston device 8, relief spring 8-5 is installed.Concrete action principle is, when passenger sits on the seat, pressure passes to piston device 8 by supporting disk 9, and bottom piston device 8, spring supporting is bottom damping chamber 5, and is to a certain degree compressed; And when there is the situations such as vibrations, relief spring 8-5 shrinking, and offsets a part of vibration energy, simultaneously due to the pressure of human body, making relief spring 8-5 slowly return to quiescence, playing the effect of damping thus.
Particularly, as shown in Figure 1, damping chamber 5 is the hollow cylindrical structure without end face, and the lower slide formula of described piston device 8 is assemblied in the inside in damping chamber 5; The outer wall 8-2 of piston device 8 lower end is along the circumferential direction provided with piston plate 8-3, and piston plate 8-3 edge is provided with seal ring 8-4.Adopt sliding type assembling can ensure that the vibrations in no matter any direction all can only be converted by the vertical direction, thus offset the vibrations that other directions of a part produce; Can to ensure that piston device 8 moves steady in damping chamber 5 in addition.A kind of mode that it is also conceivable to is, can seal high-purity nitrogen in damping chamber 5, to make effect of easing stress better.
As shown in Figure 3, piston device 8 comprises cylindric outer wall 8-2 and is coaxially assemblied in the inwall 8-1 of the cylindrical shape in outer wall 8-2, there is gap 8-6 between outer wall 8-2 and inwall 8-1.The bottom part of supporting disk 9 is furnished with pole 3, and the bottom of pole 3 is cemented on a pressure ring 10 be arranged in parallel with supporting disk 9 jointly, and pressure ring 10 can extend in described gap 8-6, is furnished with damper spring 11 in pressure ring 10 bottom part.
Piston device 8 carries the weight of human body, and when taking on the seat, the bottom of piston device 8 utilizes relief spring 8-5 to reduce pressure.This is first order damping.
Second stage damping is also provided with, even if be assemblied in piston device 8 by pole 3 bottom supporting disk 9 in this programme.Like this, between supporting disk 9 with piston device 8 be also movable connection.Have multiple pole 3 bottom supporting disk 9, pole 3 is fixed on same pressure ring 10.The width of pressure ring 10 is less than the gap 8-6 width of piston device 8 outer wall 8-2, inwall 8-1, and such pressure ring 10 can directly be put among the 8-6 of gap.Damper spring 11 bottom pressure ring 10, can play good cushioning effect.When car body does not produce vibrations, damper spring 11 keeps state of equilibrium under the effect of the pressure, geo-stationary; And when having vibrations to produce, damper spring 11 offsets part vibrations, and slowly recover after deformation, then get back to state of equilibrium.
This programme further discloses third stage damping:
The inwall 8-1 inside of piston device 8 is provided with air bag post 4, and the end face of air bag post 4 stretches out the upper end of piston device 8.Be hollow among piston device 8 inwall 8-1, this programme is wherein assembled with the air bag post 4 that an inside is filled with air.The material of air bag post 4 requires stretch-proof, good springiness.Under normal circumstances, above, two-stage damping can meet damping requirement.If but in vehicle travel process, run into the hollow on road surface; cause car body produce instantaneously shake by a relatively large margin time; relief spring 8-5 in first order damping, second stage damping, damper spring 11 moment is compressed largely; in order to prevent excessive displacement; be provided with air bag post 4; namely when damper spring 11 is compressed to a certain degree; the bottom of supporting disk 9 will contact with air bag post 4; under the elastic reaction of air bag post 4; offset remaining vibration energy, play a safety guard-safeguard effect.
As shown in Figure 1, be the structural representation of automotive seat, seat 13 edge tilt of automotive seat is provided with backrest plate 14, and the top of backrest plate 14 is provided with headrest 1; Seat 13 is provided with air cushion 12, and air cushion 12 also can play certain cushioning effect.This programme integral installation bottom automotive seat, convenience quick for installation, good damping effect.
Although be below described embodiment of the present utility model by reference to the accompanying drawings, but the utility model is not limited to above-mentioned specific embodiments and applications field, above-mentioned specific embodiments is only schematic, guiding, instead of restrictive.Those of ordinary skill in the art is under the enlightenment of specification sheets, and when not departing from the scope that the utility model claim is protected, can also make a variety of forms, these all belong to the row of protection of the present utility model.
