[0015] The seat is located inside the simulation cockpit shell 2 .

[0016] The electric shaft controller is used to control the up and down, left and right tilt angles of the seat to simulate the driving state of the vehicle. The electric shaft controller is connected to the host server in communication to interact with the actions of the electric shaft controller. The electric shaft controller adopts an IMAX controller. The electric shaft controller includes a control module and a trigger module. The control module has three control shafts 4 that can be extended and retracted up and down. The trigger module has an integrated circuit system that receives and transmits instructions through electronic signals. The integrated circuit system is connected to the host server in communication and is used to control the up and down extension and retraction of the three control shafts 4 to simulate the bumpy tilt of the vehicle body. The control module includes a support seat 1. The bottom end of the control shaft 4 is hinged with an articulated seat 3, and the articulated seat 3 is set on the support seat 1. The top end of the control shaft 4 is connected with a connecting seat a5, and the connecting seat a5 is hinged with a connecting seat b6. The connecting seat b6 is rotatably set at the bottom of the simulated cockpit shell 2. By adjusting the extension and retraction degree of the three control shafts 4, the adjustment of the inclination angle of the simulated cockpit shell 2 can be achieved, thereby achieving the simulated adjustment of the seat.

[0017] The simulation training device also includes a swing adjustment mechanism, which includes a mounting cover 7, a motor 8, a gear a9, a gear b10, a rotating shaft 11 and a support frame 12. The support seat 1 is rotatably arranged on the top of the mounting cover 7, the motor 8 is arranged inside the mounting cover 7, the motor 8 is drivingly connected to the gear a9, the gear a9 is meshingly connected to the gear b10, the gear b10 is arranged on the rotating shaft 11, the rotating shaft 11 is vertically distributed, the rotating shaft 11 is rotatably arranged in the mounting cover 7, the top of the rotating shaft 11 is connected to the support seat 1, and the support frame 12 is evenly connected to multiple at the bottom of the outer periphery of the mounting cover 7, which can play an effective supporting role, so that the entire simulation training device can be used in a determined position and is not easy to tip over. The motor 8 can drive the gear a9 to rotate, the gear a9 drives the gear b10 to rotate, and the gear b10 drives the support seat 1 to rotate through the rotating shaft 11, thereby realizing the rotation of the simulated cockpit shell 2 and the internal seat, expanding the range of the seat rotation, and further improving the authenticity of the driving control simulation.

[0018] The host server controls the vehicle posture data through the vehicle control data transmitted by the electric axle controller and the vehicle driving control system.
