Simulator dynamic seat

Abstract

The invention relates to a simulator dynamic seat in film videos and games, wherein a plurality of universal lifting cylinders capable of rotating according to the seat requirement are supported between a bottom frame and a seat fixation frame, the load is reduced through a gravity canceling device, and a balance frame reinforced by a metal beam or metal plate matches with a deep cross shaft coupling with an extension pipe so as to make the dynamic seat achieve the safe and large inclination angle. According to the present invention, the simulator dynamic seat has characteristics of low cost, energy saving, and high film and action synchronization, and can safely achieve the anteversion, hypsokinesis, left wing or right wing rotation inclination angle of 100 DEG C, such that the head of the people sitting on the seat inclines toward the bottom so as to increase the somatosensory authenticity and increase the stimulation degree.

Description

technical field [0001] The invention relates to a video and game dynamic seat, in particular to a simulated dynamic seat. Background technique [0002] With the application of head-mounted displays in virtual reality game machines and simulators, new requirements are put forward for the matching dynamic seats. [0003] In order to increase the authenticity of the somatosensory and improve the degree of stimulation, the person on the dynamic seat is required to be perpendicular to the ground from the upper body, and can safely lean forward, backward, swing to the left or swing to the right with an inclination angle of 100 degrees. , with the head tilted downward.

[0004] In the prior art, Chinese patents CN203710708U, CN202496756U, CN203378786U, CN102987771A, CN201643743U, and CN202891182U record that three lifting cylinders are supported between the seat mount and the chassis. When rising, the seat starts to tilt; when the inclination angle is so large that the plane of the seat fixing frame is parallel to the axis of the lifting cylinder that has not been raised, the seat cannot be controlled, and a major safety accident will occur. At this time, the seat inclination angle will not reach 90 degrees. Can not meet the requirement of 100 degrees of seat inclination; Chinese patents CN203378772U, CN202820378U, CN202105445U, CN101034503A record six lifting cylinders, adjacent to a group, there are three support points on the seat fixed frame, when the seat fixed frame One of the support points above does not rise, and when the other two support points rise under the action of the lifting cylinder, the seat starts to tilt. When the frame planes are parallel, the seat cannot be controlled, and a major safety accident will occur. At this time, the inclination angle of the seat will not reach 90 degrees, which cannot meet the requirement of a seat inclination angle of 100 degrees.

[0005] Chinese patent CN201899871U records that a multifunctional electric dynamic motion device includes an upper platform, a lower platform, and an electric cylinder. The electric cylinder is fixed on the lower platform and connected to the upper platform through a universal joint; if the electric cylinder is fixed On the lower platform, there is no freedom of rotation with the lower platform, and when the expansion and contraction of the electric cylinder is inconsistent, it will inevitably cause the bending of the electric cylinder or the lower platform. It will also twist the connecting part of the electric cylinder, or twist the electric cylinder; theoretically speaking, the dynamic motion device with this structure cannot have a swing angle, and can only move up and down, so the angle cannot reach 100 degrees

[0006] Chinese patent CN201899871U records that an auxiliary supporting mechanism is arranged between the upper platform and the lower platform, and the auxiliary supporting mechanism is fixed on the lower platform and connected with the upper platform through a universal joint; the auxiliary supporting mechanism includes a sliding sleeve, and the sliding A sliding column is installed in the sleeve, the sliding sleeve and the sliding column are cylinders, and the sliding sleeve and the sliding column are vertically slid up and down on the lower platform through the spline or key and keyway; or the sliding sleeve and the sliding column are regular polygonal cylinders, and the matching Sliding connection up and down; one connection method is that the sliding sleeve is fixedly connected with the lower platform, the universal joint is connected with the sliding column, and the other is the sliding column is fixedly connected with the lower platform, and the sliding sleeve is connected with the universal joint; this structure is used in vehicles There have been mature applications in the transmission telescopic combined universal joint device. The telescopic combined universal joint device is composed of two cross-shaft universal joints connected in the middle by a telescopic sliding sleeve and sliding column combination. , the sliding sleeve and the sliding column slide through the combination of splines or keys and keyways, or through the combination of regular square prisms and regular hexagonal prisms; this kind of telescopic combined universal joint device has many types in the aftermarket, and the sliding sleeve and sliding column can be matched. It is relatively strict, and it is also described in the drawings of this patent, and one of the connection methods is that the sliding sleeve is fixedly connected with the lower platform. If the sliding sleeve is to stabilize the seat safety, the lower end of the sliding sleeve is welded to the lower platform. At this time, the sliding sleeve The bottom end has been blocked or partially blocked, and the sliding column will be resisted up and down, which will affect the seat lift

[0007] Chinese patent CN102934914A records that an auxiliary support is provided between the seat platform and the base platform. The auxiliary support includes a base sliding sleeve and a piston type support shaft that moves vertically up and down in the base sliding sleeve. On the platform, the upper fulcrum of the piston-type support shaft is connected to the seat platform through a cross-shaft universal coupling, and the piston-type support shaft and the sliding sleeve of the base are radially positioned by splines, so that the support shaft can only Sliding up and down without rotation; the piston-type support shaft and the base sliding sleeve are radially positioned by splines, and the matching precision of this structure will be higher. If the lower end of the base sliding sleeve and the base platform are fixed tightly, the piston-type support shaft Pulling it out or inserting it will be subject to great resistance; only the base sliding sleeve is fixed on the base platform, and the weight of the seat and the audience is hundreds of kilograms. When the seat is tilted at a certain speed and at a large angle, there will be a A very large force in the horizontal direction, only relying on the bottom of the base sliding sleeve to fix the base platform, without mentioning the support device on the side of the sliding sleeve, this sliding sleeve is difficult to ensure the safety of the seat; if it is on the side of the base sliding sleeve, Welding and strengthening the diagonal brace will also cause the deformation of the sliding sleeve and the sliding of the piston rod will be blocked; if the cross-sectional size of the sliding sleeve of the base is large enough to meet the large inclination swing requirements of the seat, this will greatly increase the cost of the seat; piston support The fulcrum on the shaft is connected to the seat platform through a cross-shaft universal coupling. The bending angle of the two joints of the cross-shaft universal coupling sold in the market generally does not reach 100 degrees, so the seat platform does not It can be tilted at 100 degrees, and the seat above cannot be tilted at 100 degrees.

[0008] The common deficiency of the above several patents is that the gravity of the seat plus the audience is the resistance when the seat rises, and the gravity of the seat plus the audience is the power when the seat is lowered, so that the response speed of the rise and fall of the seat is very different. During the chair movement program, the timing cannot be accurate, which affects the synchronization of the movie and the seat movement; a large amount of gravitational potential energy is wasted, so that the use of a large motor increases power consumption and equipment costs, and generates loud noise
