Abstract

Disclosed is an air spring seat which obtains optimum effect of vibration damping by adopting the vibration reducing measures of the vibration damping apparatus, an air spring, a seat cushion, a damping block, etc. The utility model has the advantages of convenient adjustment, multiple functions, better performance, etc., improves riding comfort for automobile drivers, lightens fatigue, improves running safety, reduces driving accidents, and is suitable for vehicles with air sources.

Description

Air spring seat

The utility model relates to a kind of chair that is applicable to specific purposes, specifically a kind of seat that is used on the vehicle.

In driver's chair on the existing vehicle and the seat of applying for a patent (CN85204298), be to think simplified structure, cost-cutting simply, these are justifiable certainly.But in the safety problem of vehicle ', the driver plays a decisive role, if the driver when steering vehicle, energy is concentrated inadequately, has then increased possibility of accident occurrence greatly.Personal casualty that causes thus and economic loss then are appreciable.Therefore, can not be the loss that simplified structure, cost-cutting and not considering causes owing to safety misadventure.In the factor that the many driver's of causing energy can not be concentrated, vibration is very important one.Because constantly mechanical vibration make people's brain and nervous centralis constantly be upset, and the frequency that shakes at a certain position matches and resonates in oscillation frequency and the human body, then must make people's brain fag, and mood is fidgety, and energy just can not be concentrated.Therefore effectiveness in vibration suppression is one of seat important index, is also only satisfying the situation of this index, just can relate to the problem of simplified structure, cost-cutting.And the effectiveness in vibration suppression of these above-mentioned seats is unsatisfactory.

The purpose of this utility model just provides the desirable seat of a kind of effectiveness in vibration suppression, makes the driver take advantage of seat more comfortable, the incidence of minimizing accident.

The utility model is achieved in that promptly in the seat of being made up of backrest, seat cushion, mounting, support and hydraulic damper, add the air bellow shock attenuation unit that a cover is made up of control cock, air bag, utilize the good characteristics of gas followability, in seat, add a cover gas vibration insulating system.Rely on multistage vibration damping like this, make the effectiveness in vibration suppression of seat reach best.

Below in conjunction with description of drawings embodiment:

Fig. 1, Fig. 2 are two lateral plans of seat;

Fig. 3 is a control cock structure cutaway view.

As shown in the figure, backrest 1, seat cushion 2, mounting 4,6,

support

10,13 is formed basic seat form, and promptly seat cushion 2 is fixed on the mounting 4, and two mountings and two stands are formed four connecting rod lifting mechanisms, and be parallel to guarantee the seat lifting, invariant position.And the height of seat is adjusted in the rotation that can pass through hand button B.Also a slide rail 3 can be set between seat cushion 2 and mounting 4, by the front and back position of clamp A control seat horizontal direction.Hydraulic damper 5 is fixed between seat left side mounting 4 and the mounting 6, is small-sized hydraulic piston oil-cylinder line, and joins by an oil pump and oil circuit.Can play buffer action to huge strong top ripple, not cause the driver that fierce beating arranged, unlikely too quickly and disseat even knock ceiling when upspringing especially.Its piston rod and sleeve pipe are an integral body, and unlikely piston comes off and lost efficacy.Its seal ring is a serration, to guarantee no leak.Fix a control cock 11 on seat right side mounting 4, have one to adjust support 7 between

support

10,13, air bag 9 is positioned on the gasbag seat of adjusting support 7 centres, and links to each other with an air extractor duct of control cock 11.Form the air bellow shock attenuation unit by control cock 11, air bag 9 like this.The stiffness that the handwheel E that adjusts support 7 front ends can adjust air bellow-air bag is till comfortable.As shown in Figure 3, control cock 11 is by valve body 14, valve rod 15, and set screw 16, finger 17, dial axis 18, valve block 19,20, sliding sleeve 21, filter screen 22 are formed one termination gas circuit.Finger 17 is controlled by the pull bar 12 and the arm-tie 23 that are fixed on the support 13.When itself running the ripple vibration, mounting 6 and support 13 movement therewith, pull bar 12 and arm-tie 23 that drive links to each other with support 13 move up and down, arm-tie 23 is stirred finger 17, drive dial axis 18 and rotate, make valve rod 15 in sliding sleeve 21, move forward and backward, thus the intake and exhaust of control air bag 9, rigidity with the air bellow that guarantees to regulate is constant, reaches seat vibration damping purpose.One cock air valve can be set before the seat admission port, when stopping the seat gas circuit and in a single day leaking gas, influence car load and travel.The air bellow inlet suction port is 90 ° of bent angle joints, prevents from that gas piping is easy to wear to cause gas leakage.Air bag 9 is made by elastomeric material, and mixes glue with cord fabric or chopped fiber and strengthen, and its anti-fatigue performance is improved.Gasbag outer surface has the reticulate pattern reinforced rib, preferably adopts inside face reticulate pattern reinforced rib, to gain in strength.Air bag becomes cucurbit shape outside that several guard rings are arranged, the protection air bag.Be surrounded by a thickness on the valve block 19,20 in the control cock 11 and be 0.2 millimeter glued membrane, to increase the sealing property of valve block.Filter screen 22 available copper silk screens, mode is the employing nylon wire preferably, but saves copper, durable and cost-cutting.

Backrest 1 can adopt straight-bar to link to each other with seat cushion 2 pivotally attached hinges 8, preferably adopts by last slice 8a, sheet 8b down universal joints that baffle plate 8c and axle 8d form page, parallel to solve to both sides, coaxial precision excessive demand in also avoiding using, has distortion then to adjust defective ineffective, that the fuse commentaries on classics is motionless slightly.Handwheel D can adjust the angle of inclination of backrest; Handle C adjusts seat cushion inclination angle in the horizontal direction, thus make take more comfortable.The rubber shock-proof block also can be adorned in lower end at support 13, to play certain damping of vibrations.

The utility model adopts the level Four vibration reducing measures such as hydraulic buffer, air spring, seat cushion and shock-proof block. So that effectiveness in vibration suppression reaches best. Through measuring, be that the amplitude of seat is no more than 1 centimetre under 15 centimetres the Vibration Condition at amplitude. This seat is easy to adjust, and is multiple functional, functional. Can improve comfortableness to the car stand personnel of sailing, lessen fatigue, improve driving safety, reduce driving accident. All can use the vehicle that source of the gas is arranged.
