AI Technical Summary
Currently, the hatches of amphibious armored vehicles tend to extend beyond the vehicle body after being opened, affecting vehicle movement. Furthermore, vibrations from weapon firing can cause the hatches to swing, resulting in poor safety.
The system employs a limit mechanism, including a guide rail, a slider, a limit switch, and a limit actuator. Through the cooperation of the flip-top actuator and the limit actuator, the door is reliably limited, ensuring that the door remains stable during opening and closing.
This achieves stability and safety during the opening and closing of the hatch, preventing the hatch from extending beyond the vehicle body and swinging, thus improving the safety of vehicle movement and operation.
