Abstract

An object of the present invention is to provide a motion simulator which, despite having a simple structure, can realize various types of simulation motion and is easily installed and moved. The motion simulator of the present invention includes a rotating plate on which a motor is mounted through one side thereof and on which a plurality of casters are mounted through a lower surface thereof, the caster being configured such that, when the motion simulator is used, rotation of the caster is inhibited to allow the wheel to roll in the rotational direction of the rotating plate, and when the motion simulator is moved, the caster can be unlocked to enable the caster to rotate and the motion simulator to be freely pushed and moved; a fixing plate supporting a lower portion of the rotating plate to enable the rotating plate to be rotated and having a driven part fixedly mounted thereon and meshed with a shaft of the motor; an operating frame disposed at and spaced apart from an upper portion of the rotating plate; and a plurality of link units coupled between the rotating plate and the operating frame to support and vertically move the operating frame.

Claims

1. A motion simulator, comprising;

a rotating plate (100) on which a motor (110) is mounted through one side thereof and on which a plurality of casters (120) are mounted through a lower surface thereof;

a fixing plate (200) supporting a lower portion of the rotating plate (100) to enable the rotating plate to be rotated and having a driven part fixedly mounted thereon and meshed with a shaft of the motor (110);

an operating frame (300) disposed at and spaced apart from an upper portion of the rotating plate (100); and

a plurality of link units coupled between the rotating plate (100) and the operating frame (300) to support and vertically move the operating frame (300);

wherein the caster (120) is provided with a locking means (140) restricting yaw of the caster (120) with respect to a vertical line to lock the caster (120) at a location which is parallel to rotation of the rotating plate (100) when the motion simulator is used and to unlock the caster (120) when the motion simulator is moved, and

a rubber plate (240) is provided between a lower end portion of the fixing plate 200 and a floor (B) to allow the caster (120) to be spaced apart from the floor (B) when the motion simulator is used.

2. The motion simulator of claim 1, characterized in that a first sprocket (111) is coupled to the shaft of the motor (100) and the driven part comprises a plurality of second sprockets (210) mounted on the fixing plate (200) and a chain (220) connected to the first sprocket (111) and the plurality of second sprockets (210).

3. The motion simulator of claim 1, characterized in that the rotating plate (100) and the fixing plate (200) are coaxially disposed on one central axial line and configured such that a distance from the central axial line to the border of the rotating plate (100) is greater than a distance from the central axial line to the border of the fixing plate (200) to allow the caster (120) to be located outside the fixing plate (200).

4. The motion simulator of claim 3, characterized in that a rotating support part (230) to which a central shaft (231) is rotatably coupled is provided on an upper surface of a central portion of the fixing plate (200) to support the rotating plate 100, a through hole (101) is formed in a central portion of the rotating plate (100) to allow the central shaft (231) to vertically pass through the through hole, and a hardlock nut is coupled to the central shaft (231) passing through the through hole (101).

5. The motion simulator of claim 2, characterized in that the plurality of second sprockets (210) mounted on the fixing plate (200) are disposed at regular intervals with respect to a central axial line of the fixing plate (200) and the first sprocket (111) is eccentrically disposed outside an imaginary connecting line connecting the plurality of second sprockets (210).

6. The motion simulator of claim 1, further comprising a raising/lowering means (130) provided between the rotating plate (100) and the caster (120) for adjusting a vertical location of the caster (120).

7. The motion simulator of claim 6, characterized in that the raising/lowering means (130) comprises;

a fixing member (131) mounted on a lower surface of the rotating plate (100);

a vertical moving member (132) secured to an upper surface of the caster (120) and disposed so as to be vertically moved in the fixing member (131) along with the caster (120); and

a shaft (133) passing through an upper portion of the fixing member (131), coupled to the vertical moving member (132) through a lower end thereof and connected to a vertical driving means through an upper end thereof.
