The invention belongs to the technical field of aircraft cabin door structures, and relates to a concave undercarriage cabin door structure and an opening method. The concave undercarriage cabin door structure is installed on a cabin body (7) and comprises a left cabin door (6), a right cabin door (9), two upper unfolding mechanisms, two lower unfolding mechanisms, four upper lock initiating explosive devices (5) and two spring pin lower locks (1). The torsion spring is used as driving force for unfolding the cabin door, a traditional cabin door hydraulic driving mode is replaced, the structure is simple, and the installation space is saved. The inward-concave cabin door is unfolded through the translation-rotation type sliding rail, in the unfolding process, downward translation is conducted firstly, then rotation motion is conducted, and the problems that the installation space is small, and interference exists are solved. The device has the advantages that the inwards-concave cabin door is unfolded in a cabin with a narrow space, and it is ensured that the movement process is stable and reliable and interference does not occur.

    本发明属于飞机舱门结构技术领域,涉及一种内凹式起落架舱门结构及开启方法。内凹式起落架舱门结构安装在舱体(7)上,包括左舱门(6)、右舱门(9)、2个上展开机构、2个下展开机构、4个上位锁火工品(5)、2个弹簧销下位锁(1);本发明通过扭簧作为舱门展开的驱动力,替代了传统舱门液压驱动的形式,结构简单,节省安装空间。利用平移‑旋转式滑轨实现内凹式舱门的展开,在展开过程中,先向下平移再旋转运动,解决了安装空间小、存在干涉等问题。本发明的作用是,在狭小空间的舱室内实现内凹式舱门的展开,确保运动过程稳定可靠、不发生干涉。
