According to the automatic locking and unlocking mechanism for the folding wing rotating shaft, the folding wing rotating shaft is provided with a locking hole used for locking a lock pin, one end of a locking mechanism support is fixedly provided with a ball guide rail, and the other end of the locking mechanism support is fixedly provided with a spring support; a lock pin base capable of moving along the ball guide rail is mounted on the ball guide rail, a guide rod is mounted in the lock pin base, and the guide rod is fixedly connected with a lock pin; the spring is nested on the spring supporting rod, one end of the spring supporting rod is contacted with the rear end of the lock pin, and the other end of the spring supporting rod penetrates through and extends out of the spring support; one end of the locking mechanism pull rod is hinged to the lock pin base, the other end of the locking mechanism pull rod is hinged to the locking mechanism sliding block, and the locking mechanism sliding block is installed on the locking mechanism lead screw. The power source is connected with the locking mechanism through a lead screw. The power source drives the lock pin to retreat from the locking hole, automatic unlocking of the folding wing rotating shaft is achieved, meanwhile, under the action of the spring, the lock pin can be inserted into the locking hole, locking of the folding wing rotating shaft is achieved, the structure is reliable, and the safety performance is stable.

    一种折叠翼转轴自动锁紧解锁机构,其中,折叠翼转轴上设置有用于锁定锁销的锁定孔,锁紧机构支座一端固定安装有滚珠导轨,其另一端固定安装有弹簧支座;滚珠导轨上安装有可沿滚珠导轨移动的锁销基座,锁销基座内安装有导向杆,导向杆与锁销固连;弹簧嵌套在弹簧支撑杆上,弹簧支撑杆一端与锁销后端接触,弹簧支撑杆另一端贯通并伸出弹簧支座;锁紧机构拉杆一端与锁销基座铰接,锁紧机构拉杆另一端与锁紧机构滑块铰接,所述锁紧机构滑块安装在锁紧机构丝杠上;动力源与锁紧机构丝杠连接。本发明由动力源带动锁销从锁定孔中退出,实现折叠翼转轴的自动解锁,同时在弹簧的作用下,锁销可插入锁定孔,实现折叠翼转轴的锁紧,结构可靠,安全性能稳定。
