The working process of the utility model comprises the following steps:

1. Door opening instruction of the door lock:

Referring to fig. 7 and 8, in the initial state, the door lock is in the open state. At this time, the locking projection 23 always maintains an elastic tendency of counterclockwise rotation by the locking torsion spring 22; the push-spring driving plate 41 always maintains a leftward elastic tendency under the action of the push-spring driving plate spring 42 (since the elastic force of the locking torsion spring 22 is greater than that of the push-spring driving plate spring 42, the locking projection 23 and the push-spring driving plate 41 can always maintain a connection relationship); the door opening drive plate 31 always maintains an upward elastic tendency by the door opening drive plate spring 32.

2. Push-spring function description:

the movement trace of the positioning needle 33 is shown in fig. 9 and 10.

When the door lock is in the door-open state, the positioning pin 33 is at the door-open position a.

When the user closes the door for the first time, the locking body 2 rotates clockwise under the action of the door hook to drive the push-spring driving plate 41 to move leftwards, and the positioning needle 33 moves rightwards relative to the push-spring driving plate 41. When the positioning pin 33 passes over the door closing trigger limit step surface 412, the positioning pin 33 is impacted against the door closing trigger sound step surface 413 by the upward elastic force of the door opening driving plate spring 32 and emits a door closing trigger sound to prompt the user that the door lock has been closed. At this time, the positioning needle 33 is at the door closing triggering position b.

After the user hears the door closing trigger sound and releases his hand, the locking body 2 rotates counterclockwise under the action of the locking torsion spring 22 to drive the push-and-play driving plate 41 to move rightward, and the positioning needle 33 moves leftward relative to the push-and-play driving plate 41. The positioning pin 33 stays in the door-closing holding position c when it is affected by the door-closing holding limiting step surface 414. At this time, the door lock is in a stable door-closed state.

When the user closes the door for the second time, the locking body 2 rotates clockwise under the action of the door hook to drive the push-spring driving plate 41 to move leftwards, and the positioning needle 33 moves rightwards relative to the push-spring driving plate 41. When the positioning pin 33 passes over the door opening trigger limit step surface 415, the positioning pin 33 impacts the door opening trigger sound step surface 416 due to the upward elastic force of the door opening drive plate spring 32 and emits a door opening trigger sound to prompt the user that the door lock has been opened.

After the user hears the door opening trigger sound and releases his hand, the locking body 2 rotates counterclockwise under the action of the locking torsion spring 22 to drive the push-and-play driving plate 41 to move rightward, and the positioning needle 33 moves leftward relative to the push-and-play driving plate 41. When the positioning pin 33 moves from the door opening trigger position d to the door opening position a, the door lock completes pushing and flicking the door.

3. Switching instruction of door closing signal and door locking signal of the locking module:

Referring to fig. 11, 12 and 13, in an initial stage, since the door hook does not extend into the housing 1, the connection plate 64 is limited by the door switch connection assembly 7 to lift the door closing signal movable piece 65 so that the locking module 6 outputs the door closing signal OFF. In addition, in the initial stage, the positioning pin 33 is positioned at the operation panel unlock position e, and the lock slider 62 can lift the lock signal movable piece 63 to cause the lock module 6 to output the lock signal OFF.

Referring to fig. 14, 15 and 16, after the door is closed, the first door closing switch connecting plate 71 and the second door closing switch connecting plate 72 may be pushed by the inserted door hook to release the limit of the connecting plate 64, and the door closing signal movable plate 65 may close the contact by its restoring force to make the locking module 6 output the door closing signal ON. After the power is applied, the positioning pin 33 is located at the operation plate locking position f, and the operation plate 61 pushes the lock slider 62 open and makes the door lock signal movable piece 63 close the contact by its own restoring force to make the lock module 6 output the door lock signal ON. If the power is applied again, the positioning pin 33 returns to the operation panel unlock position e, and the lock module 6 outputs a lock signal OFF.

4. Locking and unlocking instructions of the door lock:

Referring to fig. 9 and 20, when the door lock is in the closed state and is not locked, the positioning pin 33 is located at the closed holding position c, the locking module 6 is not energized, the locking slider 62 is still located above the push-latch driving plate 41, the locking slider 62 does not lock the push-latch driving plate 41, and the door lock is in the unlocked state.

Referring to fig. 9 and 21, when the door lock is in the closed state and has been locked, the positioning pin 33 is in the closed holding position c, the locking module 6 is energized, the locking slider 62 is inserted downward into the groove of the push-latch driving plate 41, the push-latch driving plate 41 is locked by the locking slider 62 so as not to move left and right, and the door lock is in the locked state.

5. Description of electric door opening function:

Referring to fig. 9, 10 and 22, when the electric opening module 5 is energized, the electric opening operation plate 51 can move leftwards and drive the door opening driving plate 31 to rotate anticlockwise, so that the positioning pin 33 passes over the door opening limiting inclined plane 411 and reaches the door opening position a, and the electric opening action of the door lock is completed.

6. Strong door opening function description:

Referring to fig. 9, 10 and 23, when the user pushes the door when the positioning needle 33 is located at the door closing maintaining position c, the locking body 2 rotates counterclockwise, and the push spring driving plate 41 moves rightward. At this time, the positioning pin 33 is located at the door closing holding limit step surface 414 and thus the door opening driving plate 31 is also moved rightward, and since the door opening driving plate 31 is connected to the strong door opening operation plate 81, the strong door opening operation plate 81 is also moved rightward and compresses the main spring 82 (force is large) to generate a strong door opening force. When the door opening driving plate 31 is limited by the strong door opening limiting protruding points 11, the door opening driving plate 31 rotates anticlockwise, so that the positioning needle 33 passes over the door opening limiting inclined plane 411 and reaches the door opening position a, and the strong door opening action of the door lock is completed.
