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.
