Referring to fig. 5, when the door is locked, the braking member 311 cannot move away from the turning tongue 210 under the limitation of the limiting member 312, and the braking member 311 abuts against the second limiting surface 214, so that under the interference of the braking member 311, a side wall of the locking slot on the door frame cannot push the turning tongue 210 to rotate, and at this time, the first auxiliary surface 211 is always parallel to a side wall of the locking slot. The first elastic member 313 drives the braking member 311 to abut against the second limiting surface 214, so that the turning tongue 210 is reset, and the first auxiliary surface 211 is inclined from one side wall of the opposite lock groove to be parallel to the one side wall of the opposite lock groove.

Wherein, a second elastic member 314 may be disposed between the limiting member 312 and the mounting plate 220, where the second elastic member 314 can drive the limiting member 312 to move close to the braking member 311, so that the limiting member 312 re-locks the braking member 311. It is conceivable that other arrangement manners may be adopted for the first transmission portion, for example, the first transmission portion may be configured as a slot, and at this time, the protruding strip 3211 is clamped in the slot, so, when the output shaft 321 rotates, the limiting member 312 may be driven to move close to or away from the braking member 311 through the cooperation of the protruding strip 3211 and the slot, and at this time, the second elastic member 314 may not be required to be disposed.
It should be noted that, in the implementation process, other arrangements may be adopted for the first transmission portion and the second transmission portion, for example, one of the first transmission portion and the second transmission portion may be configured as a slot, the other one may be configured as a protrusion 3121, at least one slot may be configured as a slot, and at this time, the electric driving module 320 may be configured as the above-mentioned motor with the rotatable output shaft 321, or may be configured as a linear motor or an air cylinder.
