[0005] Working process and working principle of the present invention: The horizontal layer lead screw is fixed on the base plate by a horizontal layer fixed support and a horizontal layer support support. The horizontal layer lead screw is driven by a horizontal layer motor through a horizontal layer reducer and a coupling, and the movement of the connection with the horizontal layer nut support is driven to realize the movement adjustment of the horizontal azimuth group. The azimuth group is guided by a linear guide rail.

[0006] The height of the horizontal layer nut support is the same as that of the horizontal layer linear guide, so the horizontal layer partition can be connected with the horizontal layer nut support and the horizontal layer linear guide. In this way, when the slider on the horizontal layer linear guide and the horizontal layer nut support move, the horizontal layer partition can be driven to move, thereby realizing the movement of the horizontal layer. The same applies to the movement in the vertical direction.

[0007] The second bevel gear connected to the vertical layer motor is driven by the vertical layer motor, and the second bevel gear is meshed with the first bevel gear to achieve the conversion of the movement direction, so that the vertical layer lead screw is driven by the first bevel gear to move, and the vertical layer connecting plate connected to the vertical layer nut support is driven to achieve the movement adjustment of the vertical azimuth group. The azimuth group guides the movement of the vertical azimuth group through the vertical layer linear guide rail. In order to reduce the impact force encountered in the vertical direction movement, reduce the direct impact on the mechanical equipment or structure, protect the equipment from damage, smooth the vertical direction movement, reduce vibration and shaking, and improve the stability and safety of the equipment, the present invention achieves the above purpose by installing four spring elements between the vertical connecting plate and the horizontal layer partition plate through the inherent performance of the spring.

[0008] The slewing layer servo motor drives the spur gear through the slewing layer reducer, which then drives the slewing bearing to move, thereby realizing the slewing motion of the training chair. At the same time, the rotation speed output by the slewing layer servo motor can realize clockwise, counterclockwise and multiple adjustable speed slewing motions.

[0009] By moving the second orthogonal rod bracket up and down, the relationship between the upper and lower positions of the neck protector can be adjusted to meet the neck height requirements of different trainees. After adjusting to the required height position, the position of the second orthogonal rod bracket is fixed by screws to ensure that the height position of the U-shaped neck protector remains unchanged to meet the neck height requirements of different trainees. Connect to the seat back through the seat back connecting plate. Use the handle to make the vertical rod drive the neck protector to swing at different angles. After determining the swing angle, use the top screw to fix it. The final swing angle is read by the angle indicated by the pointer on the dial. By setting the position of the neck protector at different angles, more realistic working conditions and the occurrence of some emergency situations can be simulated.

[0010] Beneficial effects of the present invention: The present invention realizes adjustable movement in three directions: horizontal, vertical and rotational, and can simulate most of the flight scenarios that flight personnel need to face, providing a more realistic simulated flight experience and improving the training efficiency of flight personnel. Different flight scenarios that trainees may encounter can be simulated by controlling different rotation speeds at the same time. The addition of spring elements in the vertical movement reduces the direct impact on mechanical equipment or structures, and a dustproof device is added to the outside of the overall design system to prevent other impurities from entering the interior of the mechanical equipment. Overall, the complexity of the training seat design system is reduced, and the cost required to manufacture the training seat is reduced. BRIEF DESCRIPTION OF THE DRAWINGS
