Fig. 6 is an A portion enlarged drawing among Fig. 1.

The specific embodiment

Pneumatic dynamic seat support shown in Fig. 1,2,4 comprises base 5, chair mounted frame 6, guiding parts 4 and extensible member 2, wherein:

Base 5 is rectangular box-like members that formed by structural steel connection (as welding with the square tube steel), be used for the connection basis of guiding parts 4, extensible member 2 and bear the weight that comes from its top, as support its top seat link 6, seat 1 and seat on the guest, be connected with ground by foundation bolt.

Chair mounted frame 6 is scalariform members that formed by structural steel connection (as welding with the square tube steel); its upside is used to install seat 1; its downside is used for linking to each other with guiding parts 4, extensible member 2; can when extensible member 2 coordinations, can under the guide effect of guiding parts 4, be with seat 1 lifting, inclination and vibration by chair mounted frame 6 thus; and the limiting plate 3 below position at close two ends is fixed with respectively and stretches on it is as locating part; limiting plate is as Machine guarding, in order to avoid air bag is too high by what too kill or rise.

Guiding parts 4 sees Fig. 6 for details, it comprise a pair of guiding secondary 7 with this universal joint 8 that ways 10 of secondary 7 of leading is linked to each other, concrete, this is cylindrical member to secondary 7 one ways 9 that lead, it is installed in becomes fixing ways on the base 5, another ways 10 is an axis-shaped component, its lower end is positioned at the fixed guide member of tubular, and linear bearing 11 is installed between the two, therefore an axle shape ways can be done up and down expanding-contracting action and become movable ways in the fixed guide member of tubular, thus, fixed guide member and activity-oriented member have promptly constituted the guiding pair of a pair of telescopic slide; And the recess 14 of dome shape is arranged in the upper end of activity-oriented member, be built-in with bulb 15 and by top cover 12 it be limited in the recess 14 of dome shape at this recess 14, the upside of bulb 15 extends rod portion 13 so that be connected with other members, thus, promptly the recess 14 by dome shape has formed a spherical hinge as universal joint 8 with the bulb 15 and the top cover 12 that have bar portion, and this spherical hinge is connected with guiding is secondary; And bar portion 13 is connected on the chair mounted frame 6, can make chair mounted frame 6 around spherical hinge in any angular turn, and can play the function of constraint installing rack translation all around along secondary 7 oscilaltions of guiding.

Extensible member 2 is four air bags that can inflate and lose heart, air bag is the hyperbolic rubber air spring, can control separately by magnetic valve and corresponding pneumatic components and parts (as air pump, quick connector, choke valve, tracheae, gas receiver), rise during inflation, autocondensation during venting then can be arbitrarily angled tilts as unbalance stress.

Under the confined state, base 5 is connected with ground by foundation bolt, the fixed guide member is fixed (as by clamp nut or welding) centre at base 5, extended bar portion 13 is fixed on the centre of chair mounted frame 6 on the bulb 15, the two ends of four air bags are connected to base 5 and chair mounted frame 6 four jiaos, and the upside of chair mounted frame 6 is installed seat 1.Mechanical action can be realized between chair mounted frame 6, air bag, base 5, the guiding parts 4 thus,, the actions (seeing Fig. 3,5) such as lifting, inclination and vibration of seat can be realized by the gas that charges and discharge of pneumatic control component manipulation air bag.

During use, control system mainly is made up of programmable logic controller (PLC) (PLC) and air-operated solenoid valve.

Below be the following technical parameter of implementing this patent scheme:

Amount of seats: 2～6;

Seat adjustable height: 50～200mm;

Angle tilts: 3～12 °;

Tilt forward and back angle: 3～12 °;

Acceleration of motion: 0.5g;

Complete machine weight: 100～150Kg.

This patent product adopts air bag as motive power, can control the gas that charges and discharge of each air bag by PLC flexibly, realizes the exercises of seat platform, and advantage is as follows:

Stable action, safe and reliable.But the Pneumatic seat air bag is each load-bearing 200Kg under the 0.3MPa operating air pressure, because it is big to play lift, no matter be four-player or single, action does not almost have difference on the seat, and for safety, control voltage is direct current 24V.

Control is simple, and response is fast.Install gas receiver in addition additional under the pneumatic chair of every cover, utilize big caliber tracheae and respond magnetic valve fast, the seat support lifting only needs 0.3S.Use the PLC intelligence control system, along with the development of film plot, can be in the action of the prefabricated seat of different time sections, the prefabricated time can be accurate to 0.1S.

Environmental protection at a low price.Use hydraulic oil cylinder driving with respect to the dynamic chair of large-scale 4D movie theatre, Pneumatic seat is cheap, and uses air to be used as power not pollute the environment.

Complete machine is in light weight, easy accessibility.Pneumatic chair is by modularized design, and complete machine is divided into chair mounted frame, air bag, base, guiding parts and switch board five parts.Base and chair mounted frame are formed by the high strength construction steel integral solder, and be light solid, and guiding parts has a style of one's own and connects base and installing rack up and down, and air bag produces family's customization to specialty, and switch board is hidden to be placed between installing rack and the base.
