S10. Control the air vent 51 to be in a closed state, and detect the air pressure adjustment of the air pressure adjustment device 40;

S20. Press trigger 1;

S30 . According to the game scene, control the air pressure adjusting device 40 to adjust the air pressure in the cylinder barrel 5 , so that the gas in the cylinder barrel 5 gives feedback force to the trigger sliding rod 2 , and then transmits the feedback force to the trigger 1 .

Specifically, when the normal feedback force is required, that is, the feedback force provided by the gas in the cylinder barrel 5 to the trigger 1 is not required. At this time, the valve structure is actuated, so that the valve stem 11 moves away from the air outlet 51 and opens the air outlet 51 . After the trigger 1 is pressed, the trigger 1 rotates around the first rotating shaft 4 , so that the torsion spring 17 is compressed, and the torsion spring 17 provides the trigger 1 with a feedback force in a normal state. When the trigger 1 is released, the elastic trigger 1 of the torsion spring 17 returns to the starting position.

When the feedback force provided by the gas in the cylinder barrel 5 to the trigger 1 is required, the valve structure closes the vent 51; when the trigger 1 is pressed, the trigger 1 rotates around the first shaft 4 and compresses the torsion spring 17; at the same time, the trigger 1 passes the trigger The second rotating shaft 3 of the sliding rod 2 drives the trigger sliding rod 2 to slide in the cylinder barrel 5 , compressing the gas in the cylinder barrel 5 , and the gas in the cylinder barrel 5 gives the trigger sliding rod 2 a reverse driving force.

When the trigger 1 is released, the elastic force of the torsion spring 17 and the gas elastic force in the cylinder barrel 5 are transmitted to the trigger 1 through the trigger sliding rod, and the trigger 1 is pushed back to the starting position.

When the feedback force received by the trigger 1 needs to be adjusted, the air pressure in the cylinder barrel 5 is adjusted through the air pressure adjustment structure; the air pressure adjustment structure acts to start the first drive motor 8, and the output shaft of the first drive motor 8 rotates, thereby driving the first screw 7. Rotate in the first threaded hole 62 to realize the movement of the piston rod 6 in the cylinder barrel 5, so that the piston rod 6 compresses the gas in the cylinder barrel 5, causing a change in the air pressure in the cylinder barrel 5, so that the air pressure in the cylinder barrel 5 is changed. The change of the driving force of the gas to the trigger sliding rod 2 makes the feedback force transmitted to the trigger 1 change. When the trigger 1 is pressed, the trigger 1 rotates around the first trigger shaft 4 to compress the trigger torsion spring 17; Air. Since the air pressure in the cylinder barrel 5 increases at this time, the trigger 1 can obtain a larger air elastic force, thereby obtaining a larger feedback force.

When the trigger 1 is rotated to the maximum position, or when the trigger 1 needs to be temporarily relieved of pressure, the air release port 51 is opened to realize the instantaneous release of the air pressure in the cylinder barrel 5. Start the second drive motor 13, the output shaft of the second drive motor 13 rotates, and then drives the second screw 11 to rotate in the second threaded hole 111, so that the valve stem 11 moves in the direction of approaching or away from the cylinder barrel 5, and realizes the air leakage. The closing or opening of the port 51 can relieve the pressure of the cylinder barrel 5, thereby reducing the feedback force of the trigger 1 instantly. After the air release port 51 is opened, the first drive motor 8 is driven to act, and the piston rod 6 is slid to the initial position, that is, the maximum position where the piston rod 6 extends out of the cylinder barrel 5 .
