The embodiment of the invention provides an electric mortise lock, as shown in fig. 1, which comprises a shell assembly 1, a driving assembly 2, an electronic assembly 3, a transmission assembly 4 and a lock cylinder 5, wherein the driving assembly 2, the electronic assembly 3, the transmission assembly 4 and the lock cylinder 5 are all arranged in the shell assembly 1, and the lock cylinder 5 moves up and down under the action of the transmission assembly 4;

thus, by adopting the structure, the electronic component 3 controls the driving component 2, and the driving component 2 controls the lock column 5 to move up or down through the transmission component 4, so that locking and unlocking are realized;

specifically, the driving component 2 rotates to enable the transmission component 4 to move rightwards, and the transmission component 4 pulls the lock cylinder 5 to move downwards to realize unlocking;

the driving component 2 rotates reversely, so that the transmission component 4 moves leftwards, and the transmission component 4 pulls the lock column 5 to move upwards, thereby realizing locking.

The transmission assembly 4 comprises a push rod 41, a positioning pin 42, a connecting rod 43 and a sliding pull rod column 44, and the sliding pull rod column 44 moves left and right under the action of the driving assembly 2 to drive the connecting rod 43, the positioning pin 42 and the push rod 41 to move left and right;

the driving component 2 comprises a magnetic coil motor;

specifically, when the lock needs to be unlocked, the magnetic coil motor is powered on in the forward direction to generate a magnetic field, so that the sliding pull rod column 44 is stressed in the forward direction to move rightwards, the sliding pull rod column 44 moves rightwards to pull the connecting rod 43, the positioning pin 42 and the push rod 41 to move rightwards, and finally the sliding pull rod column 44 and the lock column 5 move downwards to realize unlocking;

when the lock needs to be closed, the magnetic coil motor is reversely electrified to generate a reverse magnetic field, so that the sliding pull rod column 44 reversely stressed to move leftwards, the sliding pull rod column 44 pulls the connecting rod 43, the positioning pin 42 and the push rod 41 leftwards to move, and finally the sliding pull rod column 44 and the lock column 5 move upwards to close the lock.

when the lock needs to be unlocked, the microprocessor 31 outputs an unlocking signal to control the forward energization of the magnetic coil motor;

when the locking is required to be closed, the microprocessor 31 monitors the state of the Hall switch module 33 in real time, and when the Hall switch module 33 generates a high level signal, the microprocessor 31 outputs a locking signal to control the magnetic coil motor to be electrified reversely.

Specifically, when the electric mortise lock is installed, a small magnet is installed right above the electric mortise lock, and when the electric mortise lock moves to the position below the magnet, the hall switch module 33 detects the magnetic force of the magnet, and generates a high-level signal at the moment to prepare for locking;

when the electric mortise lock is far away from the magnet, the hall switch module 33 does not detect the magnetic force of the magnet, and at this time, a high level signal is not generated, so that the microprocessor 31 does not output a lock-off signal.

The indicator light module 34 is used for displaying the state of the electric mortise lock, and the current working state of the electric mortise lock is represented by different colors; for example, red indicates the locked state, and green indicates the unlocked state; of course, the color is not limited thereto.

As shown in fig. 3, the housing assembly 1 is provided with a wire hole 13.

The front, the back and the side of the shell component 1 are provided with manual unlocking holes 14;

thus, when the electric lock fails to be unlocked due to sudden failure (such as power failure), manual unlocking can be performed through the manual unlocking hole 14.

The working process is as follows:

when the lock is unlocked, the microprocessor 31 outputs an unlocking signal to control the magnetic coil motor to be powered on in the positive direction to generate a magnetic field, so that the sliding pull rod column 44 is stressed in the positive direction to move rightwards, the sliding pull rod column 44 moves rightwards to pull the connecting rod 43, the positioning pin 42 and the push rod 41 to move rightwards, and finally the sliding pull rod column 44 and the lock column 5 move downwards to realize unlocking;

when the lock is closed, the microprocessor 31 monitors the state of the hall switch module 33 in real time, when the hall switch module 33 generates a high-level signal, the microprocessor 31 outputs a lock closing signal, controls the magnetic coil motor to be electrified reversely to generate a reverse magnetic field, so that the sliding pull rod column 44 is stressed reversely to move leftwards, the sliding pull rod column 44 pulls the connecting rod 43, the positioning pin 42 and the push rod 41 leftwards to move, and finally the sliding pull rod column 44 and the lock column 5 move upwards to realize lock closing.
