The invention belongs to structural design of helicopters, and relates to an automatic locking structure and an automatic locking device for a helicopter sliding cabin door. The automatic locking structure comprises a shell, an electromagnetic coil, a magnetic conductive iron core sliding block, an elastic component and a locking mechanism; the left side of the shell is open; a clamping point is arranged on the inner wall of the middle section of the shell; a slideway is formed on the inner wall of the shell on the right side of the clamping point; the electromagnetic coil is arranged on the right section of the shell; the magnetic conductive iron core sliding block is arranged in the shell and can move along the slideway; one end of the elastic component is connected with one end of the magnetic conductive iron core sliding block; the other end of the elastic component is fixed to the bottom surface of the shell; and the locking mechanism is arranged at the other end of the magnetic conductive iron core sliding block. The device can be automatically controlled, is high in reliability, simple in structure and light in weight, and meets the requirement of locking the helicopter sliding cabin door by limiting sliding cabin door rollers.

    本发明属于直升机结构设计,涉及一种自动锁定结构及用于直升机滑动舱门的自动锁定装置。自动锁定结构包括:壳体,电磁线圈、导磁铁芯滑块、弹性部件,锁止机构,其中,壳体左侧开放,壳体中段内壁设置有卡点,卡点右侧的壳体内壁形成滑道,电磁线圈设置在壳体右段,导磁铁芯滑块设置在壳体内并且能够沿着滑道运动,弹性部件一端与导磁铁芯滑块一端连接,弹性部件另一端与壳体底面固定,锁止机构设置在导磁铁芯滑块另一端。本发明的装置可自动控制、可靠性高、结构简单、重量轻,满足通过限制滑动舱门滚轮来实现锁定直升机滑动舱门的要求。
