1. An opening and closing mechanism, comprising a driving device, a locking device and a support arm; wherein,
the driving device is connected to the locking device to drive the locking device to rotate;
a first end of the locking device is rotatably mounted on a baseplate;
a sliding groove in which a second end of the locking device is slidably located is formed on the support arm;
a first end of the support arm is rotatably mounted on the baseplate; a second end of the support arm is connected to a fairing;
the driving device drives the locking device to rotate, the locking device drives the support arm to rotate by the sliding groove, so that the support arm opens or closes the fairing; and
the locking device is able to realize self-locking of the opening and closing mechanism;
the opening and closing mechanism further comprising a closed-state limit stop and an open-state limit stop, used to limit the closing and opening of the fairing in a limit stop state, respectively; wherein, the sliding groove has two opposite end sides and is arranged so that when the locking device is perpendicular to the sliding groove, the closed-state limit stop or the open-state limit stop is in the limit stop state, and there is an allowance (L) between one of the two opposite end sides that is closer to the second end of the support arm and the second end of the locking device and thus the locking device is able to move in a direction of the allowance in the sliding groove to realize self-locking.
