Abstract
The utility model relates to a seat in an operator cabin of an automobile, which belongs to the technical field of an accessory of an automobile body of the automobile. The suspending type seat with air of the utility model is composed of a seat cushion assembly, a backrest assembly, a backrest adjusting mechanism, a front and back adjusting mechanism, a damper assembly and a suspending damping mechanism, wherein, the suspending damping mechanism is mainly composed of an air sac, a height adjusting valve and a shifting fork. The seat is adjusted through the inflation of the air sac and the exhaust of the air sac. The utility model has the advantages of simple manufacturing process, convenient adjustment, good damping effect and good comfort.
Description
(1) technical field
The utility model relates to the indoor seat of vehicle drive, belongs to the technical field of auto body annex.
(2) background technology
The vehicle drive chair is selected mechanical suspension formula seat usually for use, be that the certain spring of employing rigidity is an elastic element, the body weight adjusting is to control by the pretension of adjusting spring, because the difference of factors such as road conditions and driver's body weight makes the damping effect of seat and comfort level often be subjected to certain limitation.
(3) summary of the invention
The purpose of Pneumatic Suspension seat of the present utility model is to provide a kind of seat that utilizes air bag to regulate, and makes seat have damping effect and comfort level preferably.
The purpose of this utility model is achieved in that
Pneumatic Suspension formula seat of the present utility model, form by cushion assembly, backrest assembly, backrest adjusting mechanism, fore-and-aft adjustment mechanism, vibration damper assembly, suspended shock absorbing mechanism, suspended shock absorbing mechanism is made up of upper ledge, lower frame, inner support, outer support, air bag, levelling valve, shift fork, two upper ledges and two lower frames are formed four limits of suspension type damping respectively, and all there is slideway the inboard; Interior outer support adopts the X-shaped structure to connect, and the center is fixed with screw axis, can be around the rotation of axle center, and inside and outside support front end is separately fixed at the front end of upper and lower frame with an axis and two screw axis; The other end of inside and outside support is moving at upper and lower middle slide of frame; Air bag is between upper and lower frame; Height adjusting valve and shift fork be positioned at inner support a side, height adjusting valve has admission port, air bag admission port, air bags mouth.
Pneumatic Suspension formula seat of the present utility model, for prevent that air bag or other damper elements from damaging or when losing efficacy seat can keep relative height, the lower frame front end is provided with inhibiting device.
Pneumatic Suspension formula seat of the present utility model, in order to reduce friction, the normal-running fit place of axis and screw axis all uses nylon jacket.
Pneumatic Suspension formula seat of the present utility model, the shift fork below has a rotary middle spindle, the top of turning cylinder that two set screw are arranged, and be used to regulate the position of shift fork, and shift fork is floating type.
Therefore, it is simple, easy to adjust to the utlity model has manufacturing process, has damping effect and traveling comfort preferably.

Fig. 2 is the structural representation of levelling valve of the present utility model and shift fork
Among the figure, 1. upper ledge, 2. inner support, 3. outer support, 4. lower frame, 5, air bag, 6, inhibiting device, 7 shift forks, 8. height-control valve, 9. shock absorber
(5) specific embodiment
As shown be the specific embodiment of the present utility model, it is made up of cushion assembly, backrest assembly, backrest adjusting mechanism, fore-and-aft adjustment mechanism, vibration damper assembly 9, suspended shock absorbing mechanism, suspended shock absorbing mechanism is made up of upper ledge 1, lower frame 4, inner support 2, outer support 3, air bag 5, levelling valve 8, shift fork 7, two upper ledges 1 and two lower frames 4 are formed four limits of suspension type damping respectively, and all there is slideway the inboard; Interior outer support adopts the X-shaped structure to connect, and the center is fixed with screw axis, can rotate around the axle center.Inside and outside support front end is separately fixed at the front end of upper and lower frame with an axis and two screw axis.The other end of inside and outside support can be moving at upper and lower middle slide of frame, does the vibration action that pumps with in the realization seat working process thereby the drive upper ledge is parallel to lower frame.All use nylon jacket to reduce friction at the normal-running fit place of axis and screw axis.Be provided with inhibiting device at the lower frame front end, to guarantee that seat can keep relative height when air bag or other damper elements damage or lost efficacy, the convenient driving.
The elastic element of this product is made up of air bag, height-control valve and shift fork.Air bag 5 is fixed with the air bag fixed mount between upper and lower frame.Height adjusting valve 8 and shift fork 7 be positioned at inner support 2 a side, height adjusting valve 8 has admission port P, air bag admission port A, air bags mouth E.When shift fork was depressed the valve rod I of levelling valve, mouthful P, A connected, airbag aeration, and the gas intracapsular pressure increases, and holds on the upper ledge, and seat raises.When shift fork was depressed the valve rod II of levelling valve, mouthful A, E connected, air bags, and the gas intracapsular pressure reduces, and holds under the upper ledge, and seat reduces.
Pneumatic Suspension formula seat of the present utility model, there is a rotary middle spindle shift fork below, shift fork can rotate around central screw axle O, there are two set screw the top of turning cylinder, be used to regulate the position of shift fork, the position that shift fork rotates can and be a floating by two screw adjusted, the rising and falling and play time-lag action of may command levelling valve valve rod, increase inflation (exhaust) amount of air bag, seat is highly kept relative stability when work.
Claims (4)
