Abstract
The invention discloses a three degree of freedom electric dynamic chair which is applied to entertainment venues such as a 4D (four-dimensional) cinema and a commercial game machine. The three degree of freedom electric dynamic chair comprises a base, a chair connecting plate and three sets of electric lifting mechanisms, wherein the electric lifting mechanisms are arranged between the base and the chair connecting plate, one set of electric lifting mechanism is arranged on the middle of the front end of the base, each of the left side and the right side of the rear end of the base is provided with one set of electric lifting mechanism, the three sets of electric lifting mechanisms are arranged into a regular triangle, each electric lifting mechanism comprises a spherical hinge, a servo electric cylinder and a revolute pair assembly, the upper end of each electric lifting mechanism is connected with the chair connecting plate through the spherical hinge, and the lower end of electric lifting mechanism is connected with the base through the revolute pair assembly. The two sets of electric lifting mechanisms do rotating movement in a horizontal plane and one set of electric lifting mechanism does translation movement in a vertical direction, thus the actions of front-back swinging, left-right swinging, up-ascending and down-descending, bumping and the like of the dynamic chair can be completed; and by combining with other external facilities such as a networking control system, a 3D film and television system, blowing and smoke, the three degree of freedom electric dynamic chair can bring the immersive feeling for audiences, and has the characteristics of flexibility in movement, controllable speed and acceleration, strong bearing capacity, low noise and the like.
Description
Technical field
The present invention relates to a kind of 3-degree-of-freedom electrical multidimensional seat, this multidimensional seat under the excitation of control signal can along with the 3D tv screen make synchronously rock back and forth, vacillate now to the left, now to the right, rise and fall and the action such as jolt.
Background technology
Multidimensional seat is applied in the show businesses such as 4D movie theatre and commercial game machine, can spectators be brought in the fantasy sport scene in conjunction with 3D tv screen and special-effect, gives spectators' actual experience on the spot in person.The dynamic seat of Three Degree Of Freedom is to develop on the basis of two degrees of freedom multidimensional seat, compares the translational motion that the two degrees of freedom multidimensional seat has increased vertical direction.The dynamic seat of Three Degree Of Freedom commonly used mainly drives with hydraulic pressure or air pressure in the market, on the one hand, oil, air-capacitor are easily revealed, pollute, and need the external connection power source, it is larger to take up room, on the other hand, hydraulic pressure or air pressure actuating speed and acceleration responsive are sluggish, and chair motions rule and tv screen difficulty of matching are large.
Summary of the invention
Easily pollute for above hydraulic pressure or air pressure driving, the large problems such as speed, acceleration responsive sluggishness that reach take up room, the present invention proposes a kind of 3-degree-of-freedom electrical multidimensional seat, can realize flexibly that seat rocks back and forth, vacillates now to the left, now to the right, rise and fall and the action such as jolt.
The present invention is achieved through the following technical solutions:
A kind of 3-degree-of-freedom electrical multidimensional seat comprises base, seat connecting plate and three cover electric lifting mechanisms.
Three cover electric lifting mechanisms lay respectively in the middle of the base front end, the rear end is left, the rear end is right, are positive three shapes and arrange; Every cover electric lifting mechanism all comprises ball pivot, servo electric jar and revolute pair assembly.Three angular bisectors with this positive triangle are vertical respectively for the axis of the revolute pair assembly of three cover electric lifting mechanisms.The electric lifting mechanism upper end is connected with the seat connecting plate by ball pivot, and the lower end is connected with base by the revolute pair assembly, by the mutual coordination of three cover electric lifting mechanisms, can finish the predetermined action of multidimensional seat.The upper end of ball pivot and seat connecting plate are fixed, and the lower end is connected with servo electric jar by bulb, then lock by hex nut; The two ends of revolute pair assembly are fixed with servo electric jar, base respectively.
The ball pivot of 3-degree-of-freedom electrical multidimensional seat is comprised of episphere, lower semisphere and bulb, and bulb can freely rotate in the certain space scope between episphere and lower semisphere, and upper and lower hemisphere is fixed by screw.
The revolute pair assembly of 3-degree-of-freedom electrical multidimensional seat is comprised of bearing block, bearing pin, latch, two deep groove ball bearings and contiguous block, and bearing pin is fixed by latch and contiguous block, and the bearing pin axis direction is electric lifting mechanism revolute pair direction.
The invention has the beneficial effects as follows:
(1) adopt servo electric jar as driver part, not only overcome oil, the visibly moved easy pollution of gas drive, the defective such as it is large to take up room, and make multidimensional seat movement velocity and acceleration responsive fast, can control in real time as required.
(2) three cover elevating mechanisms are positive triangle to be arranged, without space singular position and stressed even, has improved integral rigidity.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described:
As shown in Figure 1, a kind of 3-degree-of-freedom electrical multidimensional seat, it comprises base 1, seat connecting plate 2, electric lifting mechanism 3, wherein:
Shown in seeing figures.1.and.2, three cover electric lifting mechanisms 3 are installed in respectively about base 1 front end centre and rear end, it mainly comprises ball pivot 4, servo electric jar 5 and revolute pair assembly 6, wherein ball pivot 4 upper ends and seat connecting plate 2 are fixing, connection is connected in the lower end with servo electric jar, then by hex nut 7 lockings; Revolute pair assembly 6 upper ends and servo electric jar 5 are fixed by screw, and lower end and base 1 are fixed by screw.
Revolute pair assembly 6 is shown in accompanying drawing 5,6, mainly formed by bearing block 11, bearing pin 12, latch 13, deep groove ball bearing 14 and contiguous block 15, bearing pin 12 is fixing with contiguous block 15 by latch 13, contiguous block 15 and base 1 are fixed by screw, bearing block 11 and servo electric jar 5 are fixed by screw, in the seat motion process, servo electric jar 5 can freely swing along bearing pin 12 axis directions.
Can be understood by above-mentioned embodiment, servo electric jar 5 is under the excitation of control signal in the chair motions process, with different strokes, speed and the acceleration push rod that stretches, make three cover elevating mechanisms carry out the parallel coupled motion, realize that with this two rotatablely move and translational motion of vertical direction in horizontal plane, thereby finish rocking back and forth of seat, vacillate now to the left, now to the right, the action such as move up and down and jolt, in conjunction with network control system, 3D video system and outside other special efficacy facilities, such as blowing, smog and sweep leg etc., spectators can be brought in the virtual scene, give its sensation on the spot in person.
