Patent Description:
A motion simulator usually controls the movement of a seat so that a passenger on that seat is moved as well. When the movement of the seat is arranged to match particular visual content, the passenger may be tricked and believe that he is experiencing the motions within the visual content. Steward platform is a common motion simulation platform formed by six telescoping actuators. Although the Steward platform is capable of simulating various motions, the movement of one telescoping actuator is dependent on the movements of other telescoping actuators, making it difficult to control the movement of desired motions. Furthermore, the cost of the Steward platform is expensive for requiring six telescoping actuators.

<CIT> describes a flight simulating apparatus capable of directing combinations of elevation, yaw, roll, pitch and three-space accelerations to a cockpit.

<CIT> describes a conventional motion simulator.

In general, existing motion simulators have following disadvantages:.

Therefore, there is a need for a motion simulator with simple structure and able to provide various motions.

This in mind, the present invention aims at providing a motion simulator capable of simulating different motions with a simple structure.

This is achieved by a motion simulator according to claim <NUM>. The dependent claims pertain to corresponding further developments and improvements.

As will be seen more clearly from the detailed description following below, the claimed motion simulator includes a base plate, a motion platform, a first actuator, a base, a second actuator and a carrying platform. The motion platform is arranged on the base plate and movably connected to the base plate. The first actuator is arranged on the motion platform and movably connected to the motion platform. The base has a base body extending in a length direction and a base extension surface extending in a width direction. The first actuator is movably connected to the base extension surface. The second actuator is movably arranged on the base. The carrying platform is movably connected to the second actuator, wherein through a connection relationship between the base and the second actuator arranged on the base, the first actuator performs a left-right movement of the carrying platform relative to the motion platform, and the second actuator performs the forward-backward movement of the carrying platform relative to the motion platform.

<FIG>, <FIG> and <FIG> are schematic diagrams illustrating a motion simulator <NUM> according to an embodiment of the present invention. In <FIG>, <FIG> and <FIG>, an X-direction axis, a Y-direction axis and a Z-direction axis are perpendicular to each other. The motion simulator <NUM> includes a base plate <NUM>, a carrying platform <NUM>, a motion platform <NUM>, a first actuator <NUM>, a base <NUM> and a second actuator <NUM>. A horizontal level of the base plate <NUM> is adjusted by a plurality of horizontal adjustment members, and the base plate <NUM> is arranged on a horizontal plane (the plane formed by the X-direction axis and the Z-direction axis). The motion platform <NUM> is arranged on the base plate <NUM> and is movably connected to the base plate <NUM>. The carrying platform <NUM> is arranged above the motion platform <NUM> and apart from the motion platform <NUM>. The carrying platform <NUM> includes a carrier arranged on the carrying platform <NUM>. In one embodiment, the carrier may include but is not limited to a chair. In one embodiment, the carrying platform <NUM> includes a front end <NUM> and a rear end <NUM>. When a passenger sits on the carrier, the passenger faces toward the direction of the front end <NUM> and the passenger's back is toward the rear end <NUM>. The first actuator <NUM> (such as an electric cylinder) is arranged on the motion platform <NUM>, and is movably connected to (e.g., pivotally connected to) the motion platform <NUM>. The base <NUM> has a base body <NUM> extending in a length direction and a base extension surface <NUM> extending in a width direction. Wherein, the first actuator <NUM> is movably connected to the base extension surface <NUM>. The second actuator <NUM> (such as a screw rod sliding table) is movably arranged on the base <NUM>, and the carrying platform <NUM> is movably connected to the second actuator <NUM>. Wherein, the first actuator <NUM> performs a left-right movement of the carrying platform <NUM> relative to the motion platform <NUM> through the connection relationship with the base <NUM> and the second actuator <NUM> arranged on the base <NUM>, and the second actuator <NUM> performs the forward-backward movement of the carrying platform <NUM> relative to the motion platform <NUM>. In one embodiment, the left-right movement of the carrying platform <NUM> is tilting left, tilting right, moving left and/or moving right, and the frontward-backward movement of the carrying platform <NUM> is tilting forward, tilting back, moving forward and/or moving backward, but it is not limited thereto.

In one embodiment, the motion simulator <NUM> further includes a support assembly <NUM>, a driving assembly <NUM> and a plurality of rotation wheels <NUM>. The support assembly <NUM> is arranged on the motion platform <NUM> and is connected between the motion platform <NUM> and the base body <NUM>. The support assembly <NUM> includes a first support rod <NUM> and a second support rod <NUM>. The first support rod <NUM> is arranged on the motion platform <NUM>, and has one end pivotally connected to the motion platform <NUM> and another end fixedly connected to the base body <NUM>. The second support rod <NUM> is arranged on the motion platform <NUM>, and has one end pivotally connected to the motion platform <NUM> and another end fixedly connected to the base body <NUM>. The first support rod <NUM> and the second support rod <NUM> are arranged on opposite sides of the base extension surface <NUM>, respectively. The driving assembly <NUM> is arranged on the base plate <NUM> (e.g., a center of the base plate <NUM>), and configured to drive the motion platform <NUM> to rotate relative to the base plate <NUM> (e.g., clockwise rotation or counterclockwise rotation). The plurality of rotation wheels <NUM> are arranged on the motion platform <NUM> for assisting (or performing) the rotation of the motion platform <NUM>. The rotation of the motion platform <NUM> may drive the carrying platform <NUM> arranged above the motion platform <NUM> to rotate, and drive the first actuator <NUM> and the second actuator <NUM> arranged on the motion platform <NUM> to rotate. Therefore, the driving assembly <NUM> and the plurality of rotation wheels <NUM> may provide a yaw motion for a passenger on the carrier. It should be noted that the rotation angle (of yaw motion) of the motion platform <NUM> is not limited by the overall structure. Compared with a general Stewart platform, the motion platform <NUM> may provide a more realistic <NUM>-degree rotating motion.

Referring to <FIG>, the first actuator <NUM> includes a basic portion <NUM> and an extension portion <NUM>. The basic portion <NUM> is arranged on the motion platform <NUM>. A bottom end of the basic portion <NUM> is movably connected (e.g., pivotally connected) to the motion platform <NUM>. A bottom end of the extension portion <NUM> is connected to a top end of the basic portion <NUM>, and a top end of the extension portion <NUM> is movably connected to the base extension surface <NUM>. According to a control event of the basic portion <NUM>, the extension portion <NUM> is extended or retracted to perform the left-right movement of the carrying platform <NUM>. In one embodiment of the present invention, a pivot connection between the first support rod <NUM> and the motion platform <NUM> and a pivot connection between the second support rod <NUM> and the motion platform <NUM> are penetrated by a first rotation axis <NUM>. When the extension portion <NUM> of the first actuator <NUM> is extended or retracted, the base <NUM> and the carrying platform <NUM> perform the left-right movement based on the first rotation axis <NUM>. For example, when the extension portion <NUM> is extended, according to the first rotation axis <NUM>, the second actuator <NUM> and the carrying platform <NUM> are moved along the direction of the X-direction axis and/or the Y-direction axis, such that a passenger sitting on the carrier will be moved to the left (e.g., tilting left and/or moving left). For another example, when the extension portion <NUM> is retracted, according to the first rotation axis <NUM>, the second actuator <NUM> and the carrying platform <NUM> arranged on the base <NUM> moved along the opposite direction of the X-direction axis and/or the Y-direction axis, such that the passenger sitting on the carrier will be moved to the right (e.g., tilting right and/or moving right). Therefore, the left-right movement of the carrying platform <NUM> may provide a roll motion for a passenger on the carrier.

In one embodiment of the present invention, the first actuator <NUM> includes a motor and a link mechanism. The motor is configured to control the left-right movement of the carrying platform <NUM>. The link mechanism is movably connected to the motor and the carrying platform <NUM>. According to the control event of the motor, the link mechanism may perform the left-right movement of the carrying platform <NUM>. In other words, the link mechanism may replace the other first actuator (such as an electric cylinder) in the prior art to control the left-right movement of the carrying platform <NUM>. The link mechanism may reduce the computational complexity between multiple first actuators (such as electric cylinders). Please refer to <FIG> for an embodiment of the link mechanism performing the left-right movement of the carrying platform <NUM>.

Referring to <FIG>, the second actuator <NUM> includes a motor <NUM> and a conversion assembly <NUM>. The motor <NUM> is configured to perform a circular motion to control the forward-backward movement of the carrying platform <NUM>. The conversion assembly <NUM> is arranged on the base <NUM> and is movably connected between the motor <NUM> and the carrying platform <NUM>. The conversion assembly <NUM> includes a linear motion member <NUM> and a pull rod <NUM>. The linear motion member <NUM> is movably connected to the motor <NUM>, and converts the circular motion of the motor <NUM> into a linear motion along the length direction of the base <NUM> to perform the forward-backward movement of the carrying platform <NUM>. The pull rod <NUM> is movably (e.g., slidably) connected to the linear motion member <NUM> and the carrying platform <NUM> for performing the forward-backward movement of the carrying platform <NUM> according to the linear motion.

In one embodiment of the present invention, the linear motion member <NUM> includes a screw rod <NUM> and a sliding block <NUM>. The screw rod <NUM> is arranged on the base <NUM> and connected to the motor <NUM>. The sliding block <NUM> is arranged on the screw rod <NUM>, and configured to perform the linear motion on the screw rod <NUM> according to the circular motion of the motor <NUM>. The pull rod <NUM> is movably connected (e.g., pivotally connected) to the sliding block <NUM> and the carrying platform <NUM>. According to the linear motion of the sliding block <NUM>, the second actuator <NUM> performs the forward-backward movement of the carrying platform <NUM>.

In one embodiment of the present invention, according to a first joint <NUM>, the sliding block <NUM> is movably connected (e.g., pivotally connected) to an end of the pull rod <NUM>. In one embodiment of the present invention, according to a second joint <NUM>, another end of the pull rod <NUM> is movably connected (e.g., pivotally connected) to the carrying platform <NUM>. When the sliding block <NUM> performs the linear motion on the screw rod <NUM>, the carrying platform <NUM> performs the forward-backward movement of the carrying platform <NUM> based on a second rotation axis. For example, when the sliding block <NUM> slides on the screw rod <NUM> along the direction of the Z-direction axis, according to the first joint <NUM> and the second joint <NUM>, the carrying platform <NUM> is moved along a direction of the Z-direction axis and/or the Y-direction axis, such that a passenger sitting on the carrier will be moved forward (e.g., tilting forward and/or moving forward). For another example, when the sliding block <NUM> slides on the screw rod <NUM> along an opposite direction of the Z-direction axis, according to the first joint <NUM> and the second joint <NUM>, the carrying platform <NUM> is moved along an opposite direction of the Z-direction axis and/or the Y-direction, such that a passenger sitting on the carrier will be moved backward (e.g., tilting backward and/or moving backward). Therefore, the forward-backward movement of the carrying platform <NUM> may provide a pitch motion and/or a surge motion for a passenger on the carrier.

In one embodiment of the present invention, the second actuator <NUM> includes the motor <NUM> and a belt drive assembly. The belt drive assembly is movably connected to the motor <NUM> and the carrying platform <NUM>, and converts the circular motion of the motor <NUM> into the linear motion, in order to perform the forward-backward movement of the carrying platform <NUM>. Please refer to <FIG> for an embodiment of the motor <NUM> and the belt drive assembly performing the forward-backward movement of the carrying platform <NUM>.

<FIG> is a schematic diagram illustrating a motion simulator <NUM> according to an embodiment of the present invention. Referring to <FIG>, the X-direction axis, the Y-direction axis and the Z-direction axis are perpendicular to each other. The motion simulator <NUM> includes a base plate <NUM>, a carrying platform <NUM>, a motion platform <NUM>, a first actuator <NUM>, a base <NUM>, a second actuator <NUM> and a connecting assembly <NUM>. The motion simulator <NUM> may be applied to the motion simulator <NUM> in <FIG>. The mechanism of the embodiments of the base plate <NUM>, the carrying platform <NUM>, the motion platform <NUM>, the first actuator <NUM>, the base <NUM> and the second actuator <NUM> is similar to the mechanism in <FIG>, <FIG> and <FIG>. For brevity, similar descriptions for this embodiment are not repeated in detail here. The connecting assembly <NUM> is arranged between the base <NUM> and the carrying platform <NUM>. The connecting assembly <NUM> includes an upper platform <NUM>, a lower platform <NUM>, an extension member <NUM>, a rotating assembly <NUM> and a connecting member <NUM>. The upper platform <NUM> is fixedly connected below the base <NUM>. The lower platform <NUM> is arranged relative to the upper platform <NUM>. The extension member <NUM> is fixedly connected between the upper platform <NUM> and the lower platform <NUM>, and the rotating assembly <NUM> is rotatably arranged under the lower platform <NUM> through a bearing structure. The projection of the rotating assembly <NUM> on the plane formed by the X-direction axis and the Z-direction axis is fixed relative to the motion platform. In other words, when the motion platform <NUM> performs the rotation to achieve the yaw motion, the rotating assembly <NUM> is also rotated together. The connecting member <NUM> is (fixedly) arranged between the carrying platform <NUM> and the rotating assembly <NUM>, and performs a rotation based on the second rotation axis <NUM>. In one embodiment of the present invention, the motion platform <NUM> performs a rotation based on a rotation axis perpendicular to the motion platform <NUM>, and a center of the carrying platform <NUM> is aligned with the rotation axis of the motion platform <NUM>.

<FIG> and <FIG> are schematic diagrams illustrating a motion simulator <NUM> according to an embodiment of the present invention. In <FIG> and <FIG>, the X-direction axis, the Y-direction axis, and the Z-direction axis are perpendicular to each other. The motion simulator <NUM> includes a base plate <NUM>, a carrying platform <NUM>, a motion platform <NUM>, a first actuator <NUM>, a base <NUM>, a second actuator <NUM> and a plurality of stoppers <NUM> (such as a failure stop structure), a plurality of first bumpers <NUM> and a plurality of second bumpers <NUM>. The motion simulator <NUM> may be applied to the motion simulator <NUM> in <FIG>. The mechanism of the embodiments of the base plate <NUM>, the carrying platform <NUM>, the motion platform <NUM>, the first actuator <NUM>, the base <NUM> and the second actuator <NUM> is similar to the mechanism in <FIG>, <FIG> and <FIG>. For brevity, similar descriptions for this embodiment are not repeated in detail here.

Referring to <FIG>, the plurality of stoppers <NUM> are arranged on the motion platform <NUM> to control (or to limit) a movement range of the left-right movement of the carrying platform <NUM>. The plurality of first bumpers <NUM> are arranged on both sides of the base <NUM>. When the first actuator <NUM> performs the left-right movement of the carrying platform <NUM>, the plurality of first bumpers <NUM> buffer at least one impact between the base <NUM> and the plurality of stoppers <NUM>. For example, when the base <NUM> and the carrying platform <NUM> are moved along the direction of the X-direction axis, the base <NUM> hits the left stopper in <FIG>. The left first bumper in <FIG> buffers an impact between the base <NUM> and the left stopper, such that the leftward movement range of the carrying platform <NUM> is controlled. For another example, when the base <NUM> and the carrying platform <NUM> are moved in the opposite direction of the X-direction axis, the base <NUM> hits the right stopper in <FIG>. The right first bumper in <FIG> buffers an impact between the base <NUM> and the right stopper, such that the rightward movement range of the carrying platform <NUM> is controlled. Therefore, the plurality of stoppers <NUM> control the movement range of the carrying platform <NUM> to improve the safety of the motion simulator <NUM>. The plurality of first bumpers <NUM> provide the function of buffering, such that a passenger who sits on the carrier may have a comfortable experience.

Referring to <FIG>, the plurality of second bumpers <NUM> are arranged on the base extension surface <NUM>. When the second actuator <NUM> performs the forward-backward movement of the carrying platform <NUM>, at least one impact between the base extension surface <NUM> and the carrying platform <NUM> is buffered. In one embodiment in the present invention, when the carrying platform <NUM> is moved along the direction of the Z-direction axis, the carrying platform <NUM> hits the second actuator <NUM>. The right second bumper in <FIG> buffers an impact between the second actuator <NUM> and the carrying platform <NUM>, such that the forward movement range of the carrying platform <NUM> is controlled. In one embodiment of the present invention, when the carrying platform <NUM> is moved along the opposite direction of the Z-direction axis, the carrying platform <NUM> hits the second actuator <NUM>. The two left second bumpers in <FIG> buffer the impact between the second actuator <NUM> and the carrying platform <NUM>, such that the backward movement range of the carrying platform <NUM> is controlled. Therefore, the plurality of second bumpers <NUM> provide a buffering function, such that a passenger sitting on the carrier may have a comfortable experience.

<FIG> is a schematic diagram illustrating a link mechanism <NUM> of the motion simulator driving the carrying platform <NUM> to perform a left-right movement according to an embodiment of the present invention. Through extending or retracting the link mechanism <NUM>, the carrying platform <NUM> may be tilted left or right correspondingly. For example, when the link mechanism <NUM> maintains a length (e.g., the original length), a first angle A is formed between a first link rod <NUM> and a second link rod <NUM>. At this time, the carrying platform <NUM> does not be tilted left or right (as shown in the intermediate portion of <FIG>). When the carrying platform <NUM> is tilted to the right, a second angle B that is smaller than the first angle A is formed between the first link rod <NUM> and the second link rod <NUM>. At this time, the link mechanism <NUM> is retracted, and the carrying platform <NUM> may be driven by the link mechanism <NUM> to tilt right (as shown in the left portion of <FIG>). When the carrying platform <NUM> is tilted left, a third angle C that is greater than the first angle A is formed between the first link <NUM> and the second link <NUM>. At this time, the link mechanism <NUM> is extended, and the carrying platform <NUM> may be driven by the link mechanism <NUM> to tilt left (as shown in the left portion of <FIG>). Therefore, the link mechanism <NUM> provides a left-right movement to drive the carrying platform <NUM>, instead of the left-right movement of the carrying platform <NUM> through the other first actuator (such as an electric cylinder) in the prior art. The link mechanism <NUM> may reduce the computational complexity among the plurality of first actuators (such as electric cylinders).

<FIG> is a schematic diagram illustrating a motion simulator <NUM> according to an embodiment of the present invention. The motion simulator <NUM> includes a carrying platform <NUM>, a first actuator <NUM>, a motor <NUM> and a belt drive assembly <NUM>. In the motion simulator <NUM>, the belt drive assembly <NUM> is movably connected to the motor <NUM> and the carrying platform <NUM> (e.g., a rotation axis <NUM> of the carrying platform <NUM>), to convert the circular motion of the motor <NUM> into the linear motion, to perform the forward-backward movement of the carrying platform <NUM>. In other words, the motor <NUM> and the belt drive assembly <NUM> provide the forward-backward movement to drive the carrying platform <NUM>, which may replace the screw rod <NUM> and the sliding block <NUM> of the motion simulator <NUM> in <FIG> to provide a pitch motion for a passenger on the carrier.

<FIG> is a schematic diagram illustrating a motion simulator <NUM> according to an embodiment of the present invention. In <FIG>, the X-direction axis, the Y-direction axis and the Z-direction axis are perpendicular to each other, and the X-direction axis is a direction entering the diagram, such that the X-direction is omitted here for simplicity. The motion simulator <NUM> includes a base plate <NUM>, a carrying platform <NUM>, a motion platform <NUM>, a first actuator <NUM>, a second actuator <NUM>, a motor <NUM>, a set of gear and belt <NUM>, a cross bar <NUM>, a plurality of stoppers <NUM> and a plurality of bumpers <NUM>. A line connecting a center (e.g., a structural center) of the carrying platform <NUM> and a center (e.g., a rotation center) of the motion platform <NUM> is perpendicular to the motion platform <NUM>. In other words, the center of the carrying platform <NUM> is aligned with the center of the motion platform <NUM>, such that the probability of the carrying platform <NUM> is overturned when performing a pitch motion is reduced. The motor <NUM> is arranged under the carrying platform <NUM>. Compared with the motor <NUM> of the motion simulator <NUM>, the projection of the motor <NUM> on the X-Z plane does not exceed a maximum circle of the motion platform <NUM>. The set of gear and belt <NUM> is configured to drive the operation of the motor <NUM>. In accordance with the load requirement of the carrying platform <NUM>, the set of gear and belt <NUM> may amplify the torque under the same specification and condition of the motor <NUM>. The cross bar <NUM> is arranged under the carrying platform <NUM>.

Referring to <FIG>, the plurality of stoppers <NUM> and the plurality of bumpers <NUM> of the motion simulator <NUM> are configured to control (e.g., to limit) a movement range of the forward-backward movement of the carrying platform <NUM>. The plurality of stoppers <NUM> are arranged on the base body <NUM> and extend upward on both sides of the base extension surface <NUM> to control (e.g., to limit) a movement range of the forward-backward movement of the carrying platform <NUM>. The plurality of bumpers <NUM> are arranged on the plurality of stoppers <NUM> for buffering the impact force. The plurality of bumpers <NUM> may be a set of buffer foams, but the present invention is not limited thereto. When the first actuator <NUM> performs the forward-backward movement of the carrying platform <NUM> and a forward tilting angle or a backward tilting angle is too large, the cross bar <NUM> under the carrying platform <NUM> hits the plurality of stoppers <NUM>, and the plurality of bumpers <NUM> buffer at least one impact between the cross bar <NUM> and the plurality of stoppers <NUM>. For example, when the carrying platform <NUM> is moved along the direction of the Z-direction axis (e.g., a forward tilting of the carrying platform <NUM>), the cross bar <NUM> under the carrying platform <NUM> hits the right bumper of the plurality of bumpers <NUM> on the right stopper of the plurality of stoppers <NUM> in <FIG>, and the right bumper of the plurality of bumpers <NUM> in <FIG> buffers an impact between the cross bar <NUM> and the right stopper, such that the movement range of the forward movement of the carrying platform <NUM> is controlled and the impact force is buffered. When the carrying platform <NUM> is moved in the opposite direction of the Z-direction axis (e.g., a backward tilting of the carrying platform <NUM>), the cross bar <NUM> under the carrying platform <NUM> hits the left bumper of the plurality of bumpers <NUM> on the left stopper of the plurality of stoppers <NUM> in <FIG>, and the left bumper of the plurality of bumpers <NUM> in <FIG> buffers an impact between the cross bar <NUM> and the left stopper, such that the movement range of the backward movement of the carrying platform <NUM> is controlled and the impact force is buffered. Therefore, the plurality of stoppers <NUM> and the plurality of bumpers <NUM> control a movement range of the forward tilting and the backward tilting of the carrying platform <NUM>, and may also be used as a safety mechanism when the first actuator <NUM> (such as an electric cylinder) is broke down, in order to prevent the carrying platform <NUM> from unlimited forward-backward movement causing danger, so as to improve the safety of the motion simulator <NUM>. The plurality of stoppers <NUM> and the plurality of bumpers <NUM> provide a buffering function, such that a passenger who sits on the carrier may have a comfortable experience.

<FIG> is a schematic diagram illustrating a motion simulator <NUM> according to an embodiment of the present invention. In <FIG>, the X-direction axis, the Y-direction axis and the Z-direction axis are perpendicular to each other, and the Z-direction axis is a direction entering the diagram, such that the Z-direction is omitted here for simplicity. The motion simulator <NUM> includes a base plate <NUM>, a carrying platform <NUM>, a motion platform <NUM>, a first actuator <NUM>, a second actuator <NUM>, a reducer motor <NUM>, a plurality of stoppers <NUM> and a plurality of wheels <NUM>. The reducer motor <NUM> is arranged on the base plate <NUM> and configured to drive the motion platform <NUM> to rotate relative to the base plate <NUM>. The plurality of stoppers <NUM> are used to control (e.g., to limit) a movement range of the left-right movement of the carrying platform <NUM>. The method of controlling the left-right movement of the carrying platform <NUM> is similar to the plurality of stoppers <NUM> of the above-mentioned motion simulator <NUM>. For brevity, similar descriptions for this embodiment are not repeated in detail here. The shape of the plurality of stoppers <NUM> of the motion simulator <NUM> is different from the shape of the plurality of stoppers <NUM> of the motion simulator <NUM>. The shape of the plurality of stoppers <NUM> is designed as a triangle, which may reduce the possibility of deformation during the impact of the carrying platform <NUM>. The plurality of wheels <NUM> are arranged between the base plate <NUM> and the motion platform <NUM>. The plurality of wheels <NUM> may be rollers. Compared with the plurality of wheels <NUM> in the motion simulator <NUM>, the rollers may achieve a same supporting force with a smaller volume. Therefore, the distance between the motion platform <NUM> and the base plate <NUM> may be reduced, and the overall stability of the motion simulator <NUM> may be improved. When the motion simulator <NUM> uses the reducer motor <NUM> to drive the motion platform <NUM> to rotate, the plurality of wheels <NUM> just need assisting the motion platform <NUM> in supporting without driving the motion platform <NUM> to rotate.

In one embodiment, the motion platform <NUM> is detachably arranged on the base plate <NUM>. Both of the base plate <NUM> and the motion platform <NUM> have a combination interface, respectively. The two combination interfaces are aligned with each other, and the combination interfaces may be configured to be detachably connected to the first actuator <NUM> and the support assembly <NUM>. In other words, since the base plate <NUM> and the motion platform <NUM> have the two combination interfaces, respectively and aligned with each other, the motion platform <NUM> and the plurality of wheels <NUM> may be removed from the motion simulator, and the base plate <NUM> may still be connected to the first actuator <NUM> and the support assembly <NUM>, in order to provide various usages according to requirements.

<FIG> is a schematic diagram illustrating a motion simulator <NUM> according to an embodiment of the present invention. In <FIG>, the X-direction axis, the Y-direction axis and the Z-direction axis are perpendicular to each other, and the X-direction axis is a direction entering the diagram, such that the X-direction is omitted here for simplicity. The motion simulator <NUM> includes a base plate <NUM>, a carrying platform <NUM>, a first actuator <NUM>, a second actuator <NUM> and a support assembly <NUM>. For the base plate <NUM> and the motion platform <NUM> having the two combination interfaces, respectively and aligned with each other, even the motion platform <NUM> and the plurality of wheels <NUM> are removed from the motion simulator <NUM>, the first actuator <NUM> and the supporting assembly <NUM> may still be directly arranged on the base plate <NUM> of the motion simulator <NUM>.

<FIG> is a schematic diagram illustrating a base plate <NUM> and a motion platform <NUM> of a motion simulator according to an embodiment of the present invention. An outer diameter of the base plate <NUM> (e.g., <NUM>) is greater than an outer diameter of the motion platform <NUM> (e.g., <NUM>). The base plate <NUM> has a plurality of wheel interfaces <NUM> for arranging the plurality of wheels, and the motion platform <NUM> has no wheel interface. The base plate <NUM> has a plurality of caster interfaces <NUM> for arranging the plurality of casters, and the motion platform <NUM> has no caster interface. The base plate has a reducer combination interface <NUM> for arranging the reducer motor, and the motion platform <NUM> has no reducer combination interface <NUM>. The base plate <NUM> and the motion platform <NUM> have a first actuator interface <NUM> and a support assembly interface <NUM>, respectively. The first actuator interface <NUM> and the support assembly interface <NUM> are aligned with each other. The first actuator interface <NUM> is configured to arrange the first actuator <NUM>, and the support assembly interface <NUM> is configured to arrange the support assembly <NUM>.
