[0058] Specifically, the tongue body 51 is adapted to move closer to or farther from the micro switch 54 to open or close the micro switch 54;

[0059] In the above scheme, when the door body is closed, the tongue body 51 will retract under the action of the door frame, and the retracted tongue body 51 will act on the micro switch 54 to give a signal, which can be further understood as a signal that the door is locked; the tongue body 51 in the retracted state will compress the first elastic member 53, and the first elastic member 53 stores elastic potential energy. When the door is opened, the first elastic member 53 releases the elastic potential energy to cause the tongue body 51 to pop out. After the tongue body 51 pops out, it will move away from the micro switch 54, thereby causing the micro switch 54 to generate a new signal, which can be further understood as a signal that the door is not locked; this scheme, on the basis of the mechanical lock body, the tongue body 51 cooperates with the micro switch 54 to realize the door opening and closing detection of the mechanical lock body, has a simple structure, and can be detected accurately and quickly, providing a feasible implementation scheme for the door opening and closing detection of the mechanical lock body.

[0062] Specifically, in the unlocked state, the micro switch 54 is closed; in the locked state, the micro switch 54 is opened;

[0063] In the above scheme, the present application further considers that the door body is in a locked state and a closed state during most of the use time. In the locked state, the micro switch 54 is disconnected; adopting this method can effectively save electric energy.

[0064] For further information, see Figure 7 The tongue body 51 includes a tongue portion 511, a rod portion 512 and a limiting portion 513;

[0065] Furthermore, the rod body 512 is connected to the tongue body 511, and the tongue body 511 is formed with two guiding inclined surfaces.

When the rod portion 512 retracts, the first elastic member 53 is compressed on the limiting portion 513 and the first abutment plate 52. After the external force is lost when the door is opened, the first elastic member 53 releases the elastic potential energy to prompt the tongue portion 511 to reset, drive the rod portion 512 away from the micro switch 54, and realize the disconnection of the micro switch 54.

[0067] For details, see Figure 2 The main lock tongue assembly 30 includes a driving plate 31 and a main lock tongue body 32 connected to the driving plate 31.
