Fig. 1 is a schematic structural view of an embodiment of a dynamic simulation apparatus according to the present invention, and fig. 2 is an exploded structural view of the dynamic simulation apparatus in fig. 1.
Referring to fig. 1 and 2, the dynamic simulation apparatus of the present invention comprises a seat 1, an upper platform support 2, a guide 9, a yaw driving member 4 outputting a linear motion, a rotating mechanism 8, and three driving shafts 5 arranged in parallel, each driving shaft 5 being configured to output a linear motion.
The seat 1 is rotatably connected with the upper platform support 2 through a rotating mechanism 8, and the rotating shaft direction of the rotating mechanism 8 is perpendicular to the seat surface of the seat 1, wherein the upper platform support 2 is located below the seat 1 in the vertical direction.
In the initial state of the dynamic simulation device, the seat surface of the seat 1 is arranged in the horizontal direction, and the rotating shaft of the rotating mechanism 8 is in the vertical direction.
The rotating mechanism 8 may include a bearing housing, a bearing installed in the bearing housing, and a flange shaft fixed with respect to an inner ring of the bearing, wherein the bearing housing is fixedly installed in the installation hole of the upper platform bracket 2, and the seat 1 is fixed with respect to the flange shaft. Thus, the seat 1 can be rotated relative to the upper platform support 2 by the guide 9 and the yaw drive 4 to effect yaw movement.
The guide 9 is fixed relative to the seat 1 to limit movement of the seat 1 relative to the guide 9. The guide 9 has a linear slide groove 901 arranged parallel to the seating surface of the seat 1.
The yaw drive 4 is mounted on the upper platform support 2, and the mover 401 of the yaw drive 4 is arranged to output a linear motion parallel to the seat surface of the seat 1.
The mover 401 is connected with the linear sliding chute 901 in a sliding fit manner, and the direction of the linear sliding chute 901 is different from the moving direction of the mover 401. When the mover 401 controlling the yaw driving unit 4 outputs the linear motion, the mover 401 slides in the linear sliding groove 901, and further, the guide 9 and the seat 1 fixed to the guide 9 are pushed by the linear sliding groove 901 and are deflected by the rotating mechanism 8, so that the seat 1 is yawed.
The yaw driving part 4 may be configured to output a linear motion by a linear motor, an electric cylinder, an air cylinder, and the mover 401 may be, for example, a pulley mounted on a linear motion output portion of the linear motor, the electric cylinder, the air cylinder, or the like through a connecting shaft to reduce a frictional force between the mover 401 and the linear chute 901.
With reference to the absolute coordinate system setup shown in fig. 3, the Y-axis is in the vertical direction, the X-axis is in the left-right direction, and the Z-axis is in the front-back direction, wherein the rotation around the Y-axis is called yaw movement yaw, the rotation around the X-axis is called pitch movement, and the rotation around the Z-axis is called roll movement roll.
The initial state of the motion simulator may be set such that the front-rear direction of the seat 1 coincides with the Z-axis direction of the absolute coordinate system.
In the absolute coordinate system, the yaw drive 4 may be configured to enable the mover 401 to output a linear motion along the X-axis direction in the initial state of the motion simulator, and the guide 9 may be configured to enable the linear chute 901 to extend along the Z-axis direction in the initial state of the motion simulator, that is, in the initial state, the motion direction of the mover 401 of the yaw drive 4 is perpendicular to the direction of the linear chute 901.
This upper platform support 2 can include the support body and with support body fixed connection's suspension bracket 201, this suspension bracket 201 is located the below of support body on vertical direction. In this way, it is possible to mount the swivel mechanism on the bracket body to carry the seat 1 and mount the yaw drive 4 on the suspension bracket 201 to avoid the occurrence of the interference of the movement between the seat 1 and the yaw drive 4 by the compact structure.
In order to facilitate the relative fixation between the seat 1 and the guide 9, in this embodiment, the motion simulator of the present invention further includes a seat support 7, the seat 1 is connected to the rotating mechanism 8 through the seat support 7, specifically, the seat support 7 may be fixedly connected to a flange shaft of the rotating mechanism 8, the seat 1 is fixedly connected to the seat support 7, and the guide 9 is fixedly connected to the seat support 7.
Each driving shaft 5 is fixedly supported on the lower platform 3 along the vertical direction, and a linear motion output part of each driving shaft 5 is connected with the upper platform support 2 through a hinge part, wherein the hinge part can be a hooke hinge, a universal joint, a spherical hinge and the like. In this way, by controlling the stroke amount of each drive shaft 5, the vertical lifting movement of the seat 1, the pitching movement of the seat 1, and the turning movement of the seat 1 can be achieved.
According to the dynamic simulation device, each driving shaft 5 is parallelly arranged in parallel, and the overall size of the device can be obviously reduced by the structure that the driving shafts are arranged at an angle with the vertical direction; on the other hand, each driving shaft 5 is fixedly supported on the lower platform 3 without being connected to the lower platform 3 through a hinge component, which can effectively improve the rigidity of the structure below the seat 1, and improve the impact resistance and the load bearing capacity, so as to further facilitate the miniaturization design of the dynamic simulation device, and the reduction of the use of the hinge component can also reduce the cost of the dynamic simulation device and improve the market competitiveness.
Therefore, the dynamic simulation device can realize the design of four degrees of freedom through miniaturization design, and the four degrees of freedom are respectively the lifting motion of the seat 1 along the vertical direction, the pitching motion of the seat 1, the rolling motion of the seat 1 and the deflecting motion of the seat 1, so that the control on the motion posture of the seat 1 is met to a greater extent through a simple and compact structure, the dynamic simulation device can enter private places such as families, and the user experience is improved.
Each driving shaft 5 may be configured to output a linear motion by a linear motor, an electric cylinder, or an air cylinder to reduce the number of components of each driving shaft 5, reduce mechanical friction, improve service life, and implement a silent design.
Each of the driving shafts 5 may also be configured to output linear motion by a transmission structure of a motor-driven screw nut pair, a transmission structure of a motor-driven timing belt, or the like.
The above three drive shafts 5 may be arranged evenly around the turning mechanism 8, i.e. the three drive shafts 5 are arranged 120 degrees apart from each other.
The arrangement positions of the above three driving shafts 5 may be further: in the initial state of the dynamic simulation device, the central line of the first driving shaft 5 is coplanar with the rotating shaft of the rotating mechanism 8, the plane of the first driving shaft 5 and the rotating shaft of the rotating mechanism 8 is parallel to the Y axis and the Z axis and is vertical to the X axis, and the second driving shaft 5 and the third driving shaft 5 and the first driving shaft 5 form an equilateral triangle supporting structure. The structure is not only stable and reliable, but also can simplify the control algorithm of the movement posture of the seat 1.
For example, by controlling the three driving shafts 5 to generate the same stroke amount, the seat 1 can be controlled to perform the up-and-down movement. By controlling the stroke amount of the first driving shaft 5 to generate H1 and controlling the stroke amounts of the second driving shaft 5 and the third driving shaft 5 to generate H2, wherein H1 is not equal to H2, the seat 1 can be controlled to perform the pitching motion. By controlling the stroke amount of the second driving shaft 5 to generate H3 and controlling the stroke amount of the third driving shaft 5 to generate H4, wherein H3 is not equal to H4, the rolling motion of the seat 1 can be controlled.
In order to reduce the impact force and load borne by each driving shaft 5, in this embodiment, the dynamic simulation apparatus of the present invention further includes a buffer column 6, each driving shaft 5 is fixedly supported on the lower platform 3 through the buffer column 6, for example, each driving shaft 5 is fixedly supported on the lower platform 3 through four buffer columns 6, wherein four buffer columns 6 corresponding to the same driving shaft 5 form a square arrangement structure.
