When locking with a key, the key drives the rocker arm 32 to rotate back to abut against the connecting portion 22, so that the rocker arm 32 is in a natural state position. A waist-shaped hole 324 is further arranged on the rocker arm 32 and away from the second supporting column 1112.
[0057] Specifically, when the electric control fails, a key needs to be used to unlock or lock, the key is inserted into the lock core hole 31 and rotated. The key drives the rocker arm 32 to rotate around the shaft, so that the rocker arm 32 moves to the unlocking state position. The rocker arm 32 is staggered with the connecting part 22, the locking is released, and the cabin door can be manually opened. The waist-shaped hole 324 can allow the overall rocker arm waist to perform a small linear displacement. When the key is inserted into the lock core hole 31 and rotated, the rotation of the key is converted into the rocking or swinging action of the rocker arm through the waist-shaped hole 324, so that the rocker arm 32 can be smoothly switched from the natural state to the unlocking state, and the jam caused by assembly errors or component tolerances is avoided.
[0058] In some embodiments of the present application, the cabin door 1 further comprises a mounting cover 12 fixed on the side close to the mounting surface 111, and an opening 121 is further arranged on the mounting cover 12 for observing the state of the door lock.
