The invention discloses a cabin door opening and closing mechanism of an underwater vehicle. The opening and closing mechanism comprises a frame main body, wherein a skin is arranged on the periphery of the frame main body; the number of the cabin doors is two; when the cabin door is in a closed state, the cabin door and the skin define an arc-shaped structural body with the top face and the bottom face opened and the side faces closed. The first shaft is arranged at the junction of the cabin door and the skin and is fixed on the frame main body through a connecting piece; the second shaft is fixed on the cabin door through a connecting piece; the second shaft is connected with the first shaft through a connecting frame; the motor is fixed on the frame main body and is used for driving the first shaft to rotate; when the cabin door is closed and the first shaft rotates, the second shaft is driven by the connecting frame to rotate around the first shaft, and the cabin door is opened in the direction of the skin. The cabin door is opened by adopting a mode that the two doors rotate reversely outwards, so that the cabin door is slightly disturbed by water flow in an opening state, and the stability of the aircraft is ensured.
本发明公开一种水下航行器舱门开合机构。该开合机构包括:框架主体,框架主体的外围设置有蒙皮;舱门,舱门为两扇门;当舱门处于闭合状态时,舱门与蒙皮围成顶面和底面开口、侧面封闭的弧形结构体;第一轴,第一轴设置于舱门和蒙皮交界处,且通过连接件固定于框架主体上;第二轴,第二轴通过连接件固定于所述舱门上;第二轴通过连接架与第一轴连接;电机,电机固定于所述框架主体上,用于驱动所述第一轴自转;当舱门闭合、所述第一轴自转时,通过所述连接架带动所述第二轴绕所述第一轴转动,所述舱门沿所述蒙皮方向打开。本发明采用两扇门向外反转模式开舱门,能够使得舱门在开启状态下受到水流的扰动较小,保证航行器的平稳性。
