The rocking device 100 is provided, for example, below the seat, which is a rocking frame, and swings the seat to give the user sitting in the seat a realistic experience. The rocking device 100 may be used, for example, in a vehicle simulator used for training a driver. Further, the rocking device 100 is not limited to the vehicle simulator, and may be used, for example, in a flight simulator, a race game machine, or the like.

The rocking device 100 adopts a configuration that realizes left-right tilt and right-tilt in addition to left-right movement and front-back movement. By adopting such a configuration, for example, the seat can be shaken in small steps in the left-right direction or the front-back direction, so that the user can experience a situation in which the vehicle body is vibrating. Further, for example, by tilting the seat to the left or to the right for a predetermined time, the user can experience a situation in which centrifugal force is applied when turning a curve.

In the first embodiment, the movement of the left-right tilting sway frame 30 to the left and the left portion of the left-right tilting frame 30 to move upward is called "left-leaning", and the left-right tilting sway frame 30 moves to the right. At the same time, the movement of the right part upward is called "right tilt".

In each figure, the directions indicated by X1 and X2 are to the right and left, the directions indicated by Y1 and Y2 are forward and backward, and the directions indicated by Z1 and Z2 are upward and downward. These directions indicate the directions seen from the user sitting in the seat provided above the rocking device 100.

The sway device 100 has a left-right sway frame 10, a front-back sway frame 20, a left-right tilt sway frame 30, and a base 40. The base 40 is a base placed on the floor or the like. In the illustrated example, a base 40 made of a rectangular flat plate is shown.

In the first embodiment, the left-right sway frame 10 is provided above the base 40, the front-back sway frame 20 is provided above the left-right sway frame 10, and the left-right tilt is above the front-back sway frame 20. An upset frame 30 is provided. Further, although not shown, in the first embodiment, the seat, which is a swaying body, is directly mounted on the left-right tilted swaying frame 30 so as to sway according to the movement of each swaying frame included in the swaying device 100.

The base 40 should be installed on the floor or the like. In the sway device 100, the left-right tilt sway frame 30 moves relative to the base 40 to provide a seat that is a sway body that is directly or indirectly placed on the left-right tilt sway frame 30. You can be upset.

[Sway in the left-right direction]
The sway device 100 includes a drive device 12 that reciprocates the left-right sway frame 10, and a pair of

guide rails

11F and 11B that guide the reciprocating movement of the left-right sway frame 10. The arrow S1 in FIG. 1 indicates the moving direction of the left-right swing frame 10.

The pair of

guide rails

11F and 11B extend linearly in the left-right direction. Further, the pair of

guide rails

11F and 11B are separated from each other in the front-rear direction and are fixed to the base 40.

In the first embodiment, the left-right sway frame 10 is a rectangular flat plate.

A pair of moving

blocks

13F and 13B that move on the pair of

guide rails

11F and 11B, respectively, are fixed to the lower surface of the left-right sway frame 10. The moving

blocks

13F and 13B are assembled to the

guide rails

11F and 11B so as to be movable along the grooves extending in the left-right direction formed on the front side surface and the rear side surface of the

guide rails

11F and 11B, respectively. In the first embodiment, an example in which two moving blocks 13F are provided apart from each other in the front-rear direction will be shown. However, the number and position of the moving blocks 13F are not limited to the illustrated example. The same applies to the moving block 13B. The same applies to the moving blocks 23F and 23B described later.

The drive device 12 has a motor 12a, a screw shaft 12b that is rotated by the driving force of the motor 12a, and a nut portion 12c through which the screw shaft 12b is inserted. The nut portion 12c is fixed to the lower surface of the left-right swing frame 10.

The screw shaft 12b extends in the left-right direction, and a spiral groove is formed on the outer peripheral surface thereof. The nut portion 12c has a structure that moves linearly with the rotation of the screw shaft 12b. For example, the screw shaft 12b and the nut portion 12c may constitute a so-called ball screw. That is, it is preferable that the nut portion 12c contains a spherical ball that rolls in the spiral groove formed in the screw shaft 12b. Similarly, a so-called ball screw may be adopted in the

drive devices

22 and 32 described later.

For example, when the screw shaft 12b rotates in either clockwise or counterclockwise direction, the nut portion 12c moves to the left and the screw shaft 12b rotates in either clockwise or counterclockwise direction. If it moves, the nut portion 12c should move to the right.

When the screw shaft 12b is rotated by the driving force of the motor 12a, the nut portion 12c moves straight along the direction in which the screw shaft 12b extends. Along with this, the left-right sway frame 10 to which the nut portion 12c is fixed moves in the left-right direction.

With the movement of the left-right sway frame 10 in the left-right direction, the movement blocks 13F and 13B move in the left-right direction on the

guide rails

11F and 11B. With such a configuration, the movement of the left-right sway frame 10 is guided by the

guide rails

11F and 11B. Therefore, the operation of the left-right sway frame 10 is stable.

Further, in response to the reciprocating movement of the left-right sway frame 10 in the left-right direction, the front-rear sway frame 20 and the left-right tilt sway frame 30 provided above the left-right sway frame 10 also reciprocate in the left-right direction.

[Sway in the front-back direction]
The sway device 100 includes a drive device 22 that reciprocates the front-rear sway frame 20, and a pair of guide rails 21L and 12R that guide the reciprocating movement of the front-rear sway frame 20. The arrow S2 in FIG. 1 indicates the moving direction of the front-back sway frame 20.

The pair of

guide rails

21L and 21R extend linearly in the front-rear direction. The pair of

guide rails

21L and 21R are separated from each other in the left-right direction and are fixed to the left-right sway frame 10.

A pair of moving

blocks

23L and 23R that move on the pair of

guide rails

21L and 21R, respectively, are fixed to the lower surface of the front-back sway frame 20. The moving

blocks

23L and 23R are assembled to the

guide rails

21L and 21R so as to be movable along the grooves extending in the front-rear direction formed on the left side surface and the right side surface of the

guide rails

21L and 21R, respectively.

The drive device 22 has a motor 22a, a screw shaft 22b that is rotated by the driving force of the motor 22a, and a nut portion 22c through which the screw shaft 22b is inserted. The nut portion 22c is fixed to the lower surface of the front-back rocking frame 20.

The screw shaft 22b extends in the front-rear direction, and a spiral groove is formed on the outer peripheral surface thereof. The nut portion 22c has a structure that moves linearly with the rotation of the screw shaft 22b. For example, when the screw shaft 22b rotates in either clockwise or counterclockwise direction, the nut portion 22c moves forward, and the screw shaft 22b rotates in either clockwise or counterclockwise direction. If so, the nut portion 22c may be moved backward.

When the screw shaft 22b is rotated by the driving force of the motor 22a, the nut portion 22c moves straight along the direction in which the screw shaft 22b extends. Along with this, the front-rear sway frame 20 to which the nut portion 22c is fixed moves in the front-rear direction.

With the movement of the front-back sway frame 20 in the front-back direction, the movement blocks 23F and 23B move in the front-back direction on the guide rails 21F and 21B. With such a configuration, the movement of the front-back sway frame 20 is guided by the

guide rails

21L and 21R. Therefore, the operation of the front-back sway frame 20 is stable.

Further, in response to the reciprocating movement of the front-back sway frame 20 in the front-rear direction, the left-right tilt sway frame 30 provided above the front-back sway frame 20 also reciprocates in the front-back direction.

[Sway in the left-right tilt direction]

The mounting portion 30a is a flat plate having a rectangular planar shape. The front support portion 30F is a flat plate extending downward from the front end of the mounting portion 30a. The rear support portion 30B is a flat plate extending downward from the rear end of the mounting portion 30a.

The moving block 33F is fixed to the inner surface (rear surface) of the front support portion 30F. Further, the moving block 33B is fixed to the inner surface (front surface) of the rear support portion 30B. The moving

blocks

33F and 33B are assembled to the

guide rails

31F and 31B so as to be movable along the grooves extending in the left-right direction formed on the upper side surface and the lower side surface of the

guide rails

31F and 31B, respectively.

Although not shown, it is preferable that the moving

blocks

33F and 33B have a built-in spherical ball that rolls in the groove formed in the

guide rails

31F and 31B. By adopting such a configuration, the moving

blocks

33F and 33B can smoothly move on the

guide rails

31F and 31B. This is a particularly effective structure for smoothing the movement of the moving block that moves along the guide rail having a curved shape such as the

guide rails

31F and 31B. It should be noted that other moving blocks such as the moving

blocks

13F and 13B may also adopt a structure in which a spherical ball that rolls on the guide rail is built-in.

The drive device 32 has a motor 32a, a screw shaft 32b that is rotated by the driving force of the motor 32a, and a nut portion 32c through which the screw shaft 32b is inserted.

The screw shaft 32b extends in the left-right direction, and a spiral groove is formed on the outer peripheral surface thereof. The nut portion 32c has a structure that moves linearly with the rotation of the screw shaft 32b.

For example, when the screw shaft 32b is rotated either clockwise or counterclockwise, the nut portion 32c is moved to the left and the screw shaft 32b is rotated either clockwise or counterclockwise. In this case, the nut portion 32c may be moved to the right.

When the screw shaft 32b is rotated by the driving force of the motor 32a, the nut portion 32c moves straight along the direction in which the screw shaft 32b extends.

Further, the moving block 33C is fixed to the lower surface of the nut portion 32c. The moving block 33C is assembled to the guide rail 31C so as to be movable along a groove extending in the left-right direction formed on the front side surface and the rear side surface of the guide rail 31C.

The arrow S31 shown in FIG. 3 indicates the moving direction of each part when the left-right tilting sway frame 30 is tilted to the right. As will be described later, the movements of the respective parts are interlocked, and the movement to the arrow S31 is performed at the same time. Similarly, the arrow S32 shown in FIG. 4 indicates the moving direction of each part when the left-right tilting sway frame 30 is tilted to the left. The movement to the arrow S32 is also performed at the same time.

FIG. 2 shows a state in which the mounting portion 30a of the left-right tilting shaking frame 30 is parallel to the base 40 in the shaking device 100. That is, it shows a state in which the left-right tilting sway frame 30 is not tilted. FIG. 3 shows a state in which the mounting portion 30a of the left-right tilting rocking frame 30 is tilted with respect to the base 40 by moving the nut portion 32c to the right from the state shown in FIG. 2 in the rocking device 100.

FIG. 4 shows a state in which the mounting portion 30a of the left-right tilting rocking frame 30 is tilted with respect to the base 40 by moving the nut portion 32c to the left from the state shown in FIG. 2 in the rocking device 100. Shows. That is, it shows a state in which the left-right tilting sway frame 30 is tilted to the left.

When the screw shaft 32b is rotated by the driving force of the motor 32a, the nut portion 32c moves along the direction in which the screw shaft 32b extends. That is, the nut portion 32c moves in the left-right direction. As the nut portion 32c moves in the left-right direction, the front support shaft 323cF and the rear support shaft 323cB move in the left-right direction. Further, the left-right tilting sway frame 30 supported by the front support shaft 323cF and the rear support shaft 323cB moves in the left-right direction.

In this case, a seat, which is a swaying body, is mounted on the mounting portion 30a of the left-right tilting sway frame 30 via the left-right sway frame 10 or the front-rear sway frame 20. As described above, the seat may be indirectly mounted on the mounting portion 30a via a member constituting a part of the rocking device 100.

However, it is preferable to provide the left-right tilting sway frame 30 at the top. This is because the torque for driving the left-right tilting swing frame 30 can be minimized by providing the left-right tilting swing frame 30 at the top.

It is preferable that the rocking device 100 has at least a left-right tilting rocking frame 30. That is, the left-right sway frame 10 and the front-back sway frame 20 are not essential. For example, the sway device 100 may not have the left-right sway frame 10, but may have the front-back sway frame 20 and the left-right tilt sway frame 30.

In the first embodiment, the configuration in which the moving

blocks

33F and 33B are attached to the

guide rails

31F and 31B is shown, but the present invention is not limited to this. For example, wheels and the like that are arranged above and below the

guide rails

31F and 31B and rotate on the

guide rails

31F and 31B as the left-right tilting sway frame 30 moves may be provided.

In the first embodiment, the

arcuate guide rails

31F and 31B curved so as to go upward from the center toward both ends in the left-right direction are shown, but the present invention is not limited to this. For example, the

guide rails

31F and 31B may have an arc shape that is curved downward from the center toward both ends in the left-right direction.

Further, in the first embodiment, since the curvatures of the

curved guide rails

31F and 31B are constant, the movement of the moving

blocks

33F and 33B moving on the

guide rails

31F and 31B is smooth and stable. However, the curvatures of the

curved guide rails

31F and 31B do not have to be constant.

In the first embodiment, an example in which a pair (two) of guide rails such as

guide rails

11F and 11B are provided has been shown, but the present invention is not limited to this, and the number of guide rails may be one. There may be three or more.

In the first embodiment, a configuration that enables movement in the left-right direction, the front-back direction, and the left-right tilt direction is adopted, but by changing the direction in which the rocking device 100 is installed by 90 degrees, the front-back direction and the left-right direction can be changed. It may allow movement in the direction and in the anteroposterior tilt direction. That is, the rocking device 100 may be arranged so that the direction in which the screw shaft 32b of the drive device 32 extends is the front-rear direction. In that case, the left-right tilting sway frame 30 operates so as to tilt back and forth. This makes it possible for the user to experience a situation in which the vehicle travels on a road that slopes forward or backward.

In the first embodiment, an example in which the left-right sway frame 10 and the front-back sway frame 20 move in directions orthogonal to each other is shown, but the present invention is not limited to this, and at least the left-right sway frame 10 and the front-back sway frame 20 are used. It suffices if they can be moved so as to intersect each other. The same applies to the left-right tilting sway frame 30. That is, the direction in which the screw shaft 32b that reciprocates the left-right tilted sway frame 30 extends is not limited to those that are orthogonal or parallel to the direction in which the left-right sway frame 10 and the front-back sway frame 20 move.

[Second Embodiment]
